CONVEYING DEVICE AND METHOD FOR MOUNTING A CABLE CONDUIT
ON A CONVEYING DEVICE
Description
The present invention relates to a conveying device for conveying containers
and / or container
closures and a method for mounting a cable conduit on a conveying device,
which in particular
conveys containers and / or container closures in a container treatment plant.
In a container treatment plant, container goods, such as trading units or
container closures or
containers, in particular bottles, cans, etc., are conveyed by a conveying
device between
various container treatment machines or to or away from container treatment
machines, such
as a labeling machine, a filling machine, a capper, a packaging machine and
the like.
Depending on the application, a plurality of containers can be conveyed in a
row next to one
another on a conveyor belt, in the so-called mass convey, or else conveyed
individually in a
row one after the other in a conveying direction.
For electrical connections between the individual machines in the container
treatment plant
electrical lines are guided in particular by at least one cable conduit. It is
possible to guide such
a cable conduit along the conveying device. For this purpose, the cable
conduit or the cable
conduits can be attached, for example, to a carrier plate on the wall.
However, if there is no
wall, it is also conceivable to attach the cable conduit to the conveying
device. For this
purpose, it is currently necessary to provide separate holding elements for
special cable
conduit holders. For mounting the cable conduit holders to the holding
elements, two screws
are to be untightened completely on the conveying device so that a cable
conduit holder can
be installed between a holding element and a washer. This type of mounting or
assembly is
time consuming and therefore expensive and consequently disadvantageous.
A further disadvantage is that cable conduit holders in very different shapes
are needed to
cover the possibilities for different guide heights of the lines on the
conveying device, the
1
CA 03043357 2019-05-09
different cable conduits in terms of their shape and the different spaces to
the conveying
device, such as occur on curves, for example. As a result, more cable conduit
holders than
actually needed are to be hold available for mounting the cable conduit at the
installation site.
Because of this, more cable conduit holders than actually necessary are to be
send to the
installation site, so that the correct cable conduit holders are available in
the required quantity.
This causes high conveying and storage costs.
Therefore, it is an object of the present invention to provide a conveying
device and a method
for mounting a cable conduit on a conveying device with which the
aforementioned problems
can be solved. In particular, a conveying device and a method for mounting a
cable conduit to
a conveying device are provided in which the cable conduit holder with
different cable conduits
is compatible and configured so that the installation of a cable conduit in a
container treatment
plant for different cable conduits is simple, flexible and inexpensive to
carry out.
This object is achieved by a conveying device according to claim 1. The
conveying device has
a conveying element for making contact with at least one part of the
containers or container
closures, at least in some sections or temporarily, while they are conveyed in
a predefined
conveying direction, the conveying element being supported on a frame, and at
least one cable
conduit holder for holding a cable conduit, wherein the at least one cable
conduit holder is
configured to mount the cable conduit holder on the conveying device without
tools and to
accommodate the cable conduit without tools.
In the conveying device, the cable conduit holder is compatible for various
cable conduits. In
practice, about 80% of all mounting situations occurring in a container
treatment plant can be
covered with the described cable conduit holder. Therefore, the variety of
variants of cable
conduit holders to be hold available can be reduced significantly.
Another advantage is that no tool is needed for mounting or for the assembly
of the described
cable conduit holder. Therefore, for the mount of the described cable conduit
holder a
considerable part of the required mounting time can be saved per cable conduit
holder with
2
CA 03043357 2019-05-09
respect to a mount in which, for example screws are to be untightened with a
tool, then the
cable conduit holder is to be threaded and then the screws are to be tightened
again with the
help of tools. This results in a reduction of mounting costs.
Due to the various recesses, all cable conduits themselves or supports for the
at least one
cable conduit can be locked to the cable conduit holder very easily, quickly
and safely and can
be fixed additionally with a lug if necessary.
"Is supported on a frame" means, in particular, that the conveying element is
movably or
fixedly positioned on the frame and / or is supported by the frame.
Advantageous further embodiments of the conveying device are specified in the
dependent
claims.
Preferably, the cable conduit holder is configured for mounting without tools
of at least two
different cable conduit geometries and / or for mounting without tools of at
least one cable
conduit geometry at different heights on the cable conduit holder and to the
conveying
element.
Preferably, the cable conduit holder is configured for mounting without tools
to provide a form-
closed accommodation of a part of the frame in at least one axis of the frame.
Herein, the
cable conduit holder can be configured such that the form-closed accommodation
is effected
by fastening on the conveying device so that a movement of the cable conduit
holder and / or
the cable conduit is possible only in one axis of the conveying device.
Possibly, the cable conduit holder comprises a mounting unit for accommodating
a
correspondingly shaped part of the conveying device, and at least one holding
unit for
accommodating the cable conduit.
3
CA 03043357 2019-05-09
In this case, the mounting unit has substantially a counter part of the shaped
part of the
conveying device on which the mounting unit is to be suspended for forming a
form closure for
form-closed accommodation.
It is also conceivable that the mounting unit comprises a recess for the form-
closed
accommodation of a washer or a screw or nut of a screw fastener for a railing
post on the
frame, and / or the mounting unit is positioned on a first side of the cable
conduit holder, which
is averted from a second side of the cable conduit holder, on which the at
least two holding
units are positioned, and / or the cable conduit holder is bent from a piece
of sheet metal, and /
or the cable conduit holder has a U-shape, at the bottom of which at least two
holding units
are positioned and on whose two legs the mounting unit is positioned.
Preferably, the mounting unit is positioned at one end of the cable conduit
bracket, wherein the
at least two support units are positioned at the other end of the cable
conduit holder.
It can also be that the mounting unit comprises a first pair of hooks which
are positioned side
by side in a first direction and are configured for a form-closed
accommodation of a part of the
frame, and at least one further hook which is positioned in a second
direction, which differs
from the first direction, adjacent to the first pair of hooks and is
configured for a form-closed
accommodation of a part of the frame, wherein the hooks are positioned spaced
from one
another at the one end of the cable conduit holder.
There may be differently shaped holding units are provided, which are
positioned spaced apart
from one another in a row next to each other on the cable conduit holder, and
/ or wherein a
holding unit comprises a recess in at least two sides of the cable conduit
holder, and / or
wherein a holding unit comprises a slot-shaped recess which comprises a lug
and / or which
comprises a recess at its both ends, and / or wherein a holding unit comprises
an oval or round
opening which is positioned adjacent to a slot-shaped recess on the cable
conduit holder for
attaching further elements to the cable conduit holder.

CA 03043357 2019-05-09
In one implementation, the conveying device also has a cable conduit held by
the at least one
cable conduit holder and configured to accommodate an electrical cable or
line, and at least
one clip configured to accommodate a pipe for guiding a liquid or gaseous
medium on the
cable conduit, wherein the at least one clip is configured to be mounted
without tools to the
cable conduit. Additionally or alternatively, the at least one clip is adapted
to the cable conduit
such that the clip is displaceable or is not displaceable along the cable
conduit on the cable
conduit. Additionally or alternatively, the at least one clip comprises two
clip hooks which are
configured for mounting the clip on the cable conduit without tools.
The object is also achieved by a method for mounting a cable conduit on a
conveying device
according to claim 12. The conveying device is configured to convey containers
or container
closures and comprises a conveying element for making contact with at least
one part of the
containers or container closures, at least in some sections or temporarily,
while they are
conveyed in a predefined conveying direction, the conveying element being
supported on a
frame, wherein the conveying element is supported on a frame. The method
comprises the
steps: mounting, without tools, a cable conduit holder on the conveying
device, wherein the
cable conduit holder is configured for tool-less mounting of the cable conduit
holder on the
conveying device, and mounting, without tools, the cable conduit on the cable
conduit holder,
which is configured for accommodating the cable conduit without tools.
The method achieves the same advantages as previously mentioned with respect
to the
conveying device.
Further possible implementations of the invention also include not explicitly
mentioned
combinations of features or implementations described above or below with
regard to the
embodiments. The skilled person will also add individual aspects as
improvements or additions
to the respective basic form of the invention.
The invention is described below with reference to the accompanying drawings

numerals, unless stated otherwise.
In the figures, identical or functionally identical elements, unless otherwise
indicated, are
provided with the same reference numerals.
Fig. 1 shows a conveying device 1, which is configured for conveying
containers 5 and / or
container closures 6. The containers 5 and / or container closures 6 can be
conveyed
individually or packaged in packaging units, such as trading units, cartons,
etc. The conveying
device 1 can be part of a container treatment plant in which the containers 5
are treated, like
labeled and / or printed, filled with a product, closed with the container
closure 6, packaged,
inspected, etc., or conveyed by the conveying device 1. The containers 5 are
in particular
transparent or non-transparent containers, plastic bottles, glass bottles,
metal cans, empty, full,
7
1
CA 03043357 2019-05-09
closed, unlocked, labeled, not labeled, printed, etc. However, the containers
5 may also be, for
example, boxes, cartons, packages, etc.
The conveying device 1 has a frame 10, on which, in the view of Fig. 1, two
cable conduit
holders 20 are mounted spaced from each other and hold or accommodate a cable
conduit 30.
The frame 10 has a first railing 11 and a second railing 12, which are
positioned substantially
parallel to each other, so that the container 5 can be guided between the
first and second
railings 11, 12. The first and second railings 11, 12 are secured respectively
with holding rods
13 to railing posts 14 which are accommodated in railing holders 15. The
railing holders 15 are
fastened to supports 16, 17, even if the railing holders 15 are not visible on
the support 16 in
Fig. 1.
The containers 5 are conveyed by means of a conveyor belt 19 (Fig. 8), not
visible in Fig. 1,
along the first and second railing 11, 12 on the supports 16, 17 in a
predetermined conveying
direction TR, which is illustrated in Fig. 1 by a white block arrow. Thus, the
first and second
railings 11, 12, the conveyor belt 19 (Fig. 8) and optionally the supports 16,
17 are each a
conveying element which contacts the containers 5 when they are conveyed in
the predefined
conveying direction TR. Herein, the frame 10 is configured with the supports
16, 17, the
holding rods 13 and the railing posts 14 for storing the first and second
railings 11, 12 as
conveying elements.
Thus, for example, the conveying element can be a guide railing that contacts
the containers 5
and / or container closures 6, for example, on their side when they are
conveyed through a
curve or pressed against the railing 11, 12 by stagnation pressure. However,
the conveying
element can also be a conveyor belt 19 (Fig. 8) on which the containers 5 are
conveyed
standing upright. In both cases, if necessary, only a portion of the container
5 and / or the
container closure 6, such as the container bottom or a portion of the
container side wall in the
vertical or horizontal direction of the container 5, etc., is contacted. In a
mass convey of the
containers 5 and / or container closures 6, in which more than one container 5
can be
accommodated between two spaced handrails 11, 12, the railings 11, 12 as a
conveying
8
CA 03043357 2019-05-09
element can contact the container 5 and / or container closures 6 also only
temporarily, since
the container 5 can be guided in this case only on the conveyor belt and not
on the railings 11,
12.
Fig. 2 illustrates the railing holder 15 in more detail. The railing holder 15
has a C-shaped base
body 150, whose ends are each bent lug-shaped. In the ends of the base body
150 openings
151 are provided through which a non-illustrated fastening element can be
inserted to mount
and thereby secure the railing holder 15 to one of the supports 16, 17 of the
conveying device
1 of Fig. 1.
In addition, the railing holder 15 has according to Fig. 2 two post receiving
or post-
accommodating openings 152, which are positioned in slot-shaped recesses 153.
In Fig. 2,
only one of the two post-accommodating openings 152 is visible. The slot-
shaped recesses
153 extend at one end thereof to a first screw fastening 15A or a second screw
fastening 15B,
with which the slot-shaped recesses 153 can be narrowed in order to fix a
railing post 14
shown in Fig. 1 in the post-accommodating openings 152 of Fig. 2. For this
purpose, the first
screw fastener 15A has a screw 154, two washers 155 and a nut 156. The screw
154 is
inserted through a washer 155 and then from one side through a first hollow
cylindrical part of
the base body 150. The hollow cylindrical part of the base body 150 is a
hollow cylinder which
is not completely closed inwards. Therefore, the respective washer 155 abuts
to the railing
holder 15 with only a portion of its surface. On the other side of the hollow
cylindrical part of
the base body 150, the second washer 155 abuts. The screw 154 and the two
washers 155
are secured with the nut 156, which is screwed onto a non-visible screw thread
of the screw
154. Alternatively, the screw 154 and the nut 156 may be configured as two
separate screws
.. that are screwed into the railing holder 15.
The second screw fastener 15B has a screw 157, two washers 158 and a nut 159.
The second
screw fastener 15B is mounted on a second hollow cylindrical part of the base
body 150 in the
same manner as the first screw fastener 15A, as illustrated in Fig. 2.
Alternatively, the screw
9
CA 03043357 2019-05-09
157 and the nut 159 may be implemented as two separate screws which are
screwed into the
railing holder 15.
The railing holder 15 thus serves to fix the railing post 14 introduced from
above into the railing
holder 15 in two points in a force-locking manner by clamping the railing post
14 into the railing
holder 15 via the screws 154, 157. These screws 154, 157 and / or the screw
head washers
155, 158 which are inserted between the railing holder 15 serve as a point for
attaching the
cable conduit holder 20. Thus, the cable conduit holder 20 is fixed by a form-
lock with the
railing holder 15 and mounted vertically to the conveying plane. If the
conveying device 1 of
Fig. 1 is straight, the cable conduit holder 20 preferably points downwards at
an angle of 900
,
as described in more detail below.
Fig. 3 shows in more detail the cable conduit holder 20, on which a mounting
unit 21 and a
plurality of holding units 25 are provided. The mounting unit 21 is positioned
at one end of the
cable conduit holder 20. The plurality of holding units 25 is positioned at
the other end of the
cable conduit holder 20. In addition, the mounting unit 21 is positioned on a
first side of the
cable conduit holder 20, which is averted from a second side of the cable
conduit holder 20, on
which the holding units 25 are positioned.
The cable conduit holder 20 is preferably formed in one piece. For example,
the cable conduit
holder 20 is formed of a sheet metal or sheet metal bent part which is bent
into a U-shape after
punching out the desired shapes for the mounting unit 21 and the holding units
25 from the
planar sheet, as shown in Fig. 3. At the bottom and / or the two legs of the U-
shape, the
holding units 25 are positioned. The mounting unit 21 is positioned in the two
legs of the U-
shape.
The mounting unit 21 has a first hook 211, which forms a first semicircular
recess 212, a
second hook 213, which forms a second semicircular recess 214, a third hook
215, which
forms a third semicircular recess 216, and one in Fig. 3 invisible fourth hook
forming a fourth
semicircular recess. Depending on the application, however, the fourth hook
can be omitted.
CA 03043357 2019-05-09
The mounting unit 21, more specifically its three or four recesses 212, 214,
216, is adapted to
the shape of the first and second screw fasteners 15A, 15B of Fig. 4. More
specifically, the
three or four recesses 212, 214, 216 are each adapted to the outer shape or
geometry of a
washer 155, 158 or a screw 154, 157 or nut 156, 159. Therefore, the mounting
unit 21 can be
fastened form-locking to the first and second screw fasteners 15A, 15B as
shown in Fig. 4. The
attachment can be done without tools by setting the mounting unit 21 with its
first and second
hook 211, 213 on the washers 155 or the screw 154 or the nut 156 and with its
third hook 215
and the fourth hook not shown on the washer 158 or the screw 157 or the nut
159. Depending
on the configuration of the hook 211, 213, 214 and recesses 212, 214, 216, a
slight press fit
may be advantageous. For this purpose, the respective inner diameter of the
recesses 212,
214, 216 has a slightly smaller value than the outer diameter of the washers
155, 158 or
screws 154, 157 or nuts 156, 159. It is also conceivable that the hooks 211,
213, 215 or
recesses 212, 214, 216 are adapted to any other form not described here and
thus each
formed as a counterpart to the shape.
According to Fig. 3, each of the holding units 25 has a slot-shaped recess 251
or a slot-shaped
recess 258, each having a cavity 252 at its two ends. The cavities 252 are
each provided on
sides of the cable conduit holder 20 which are positioned transversely to the
side of the cable
conduit holder 20, which faces the cable conduit 30 when the cable conduit 30
is mounted on
the cable conduit holder 20. In a part of the slot-shaped recesses 251, 258 at
its one edge,
namely in the middle between the two cavities 252, two cuts or dividing lines
are provided
transversely to the edge of the recess 251, 258, so that a lug 253 is formed.
In Fig. 3, the lugs
253 are each bent in the direction of the associated cavities 252, wherein the
bending line of
the lugs 253 is positioned approximately parallel to the slot-shaped recesses
251, 258. The
lugs 253 are thereby also each bent in the direction of the mounting unit 21.
In the lugs 253 is
provided in each case a perforation or opening 254, which is configured in the
illustrated
example as a round opening. At each of the openings 254, further parts can be
fastened,
which otherwise would have to be circumvented laboriously due to the
installation of the cable
conduit 30.
11
CA 03043357 2019-05-09
The slot-shaped recesses 251, 258 are each positioned approximately parallel
to each other.
However, in the example of Fig. 3, the slit-shaped recesses 251, 258 have a
different width. In
addition, the space between the slot-shaped recesses 251, 258 is different.
The width and the
space depend on which cable conduit 30 is to be held with the cable conduit
holder 20.
Preferably, the number, width and the space between the recesses 251, 258 are
selected so
that the largest possible number of different cable conduits 30 can be held
with the cable
conduit holder 20. It is possible that the same recess 251, 258 is used to
hold a plurality of
cable conduits 30 of different geometry in order to minimize the number of
necessary recesses
251, 258 despite high variability of the cable conduit holder. At least one
recess, in particular a
recess having a higher slot height, such as the recesses 258, may be provided
for
accommodating a cable conduit cover, not shown. The holding units 25 are thus
spaced from
one another in a row next to each other on the cable conduit holder 20.
Of course, other implementations of the cable conduit holder 20 are possible,
which are
configured for a tool-free mount of at least two different cable conduit
geometries and / or for a
tool-free mount of at least one cable conduit geometry at different heights on
the cable conduit
holder 20 and to the railing 11, 12 or to the conveyor belt 19 (Fig. 8), as
also described later.
Fig. 4 shows an example of a grid-shaped cable conduit 30, which comprises
bars 31, which
are transversely positioned to the railing post 14, and U-shaped bars 32. The
bars 31 are also
positioned transversely to the U-shaped bars 32. The bars 31 are each
positioned
approximately parallel to each other. The U-shaped bars 32 of the grid are
each positioned
approximately parallel to each other. The illustrated cable conduit 30 has the
same dimensions
on its side grid walls and on its grid bottom, respectively. However, the
dimensions on its side
grid walls and on its grid bottom may also be at least partially different. In
the cable conduit 30,
electrical cables or line(s) 34 can be accommodated, as shown very
schematically in Fig. 4.
If the cable conduit 30 is inserted with one of its side walls without tools
into the cable conduit
holder 20 until the bars 31 are positioned in the cavities 252, the cable
conduit 30 can be
securely received or accommodated on the cable conduit holder 20. In this way,
the cable
12
CA 03043357 2019-05-09
conduit 30 cannot easily slip out of the cable conduit holder 20. This is also
better apparent
from Fig. 5. By preferably tool-less, bending the lugs 253 in the direction of
the cavities 252
and thus the bars 31, the cable conduit 30 can be fixed even more firmly to
the cable conduit
holder 20. The lugs 253 thus provide a further lock of the cable conduit 30 to
the cable conduit
holder 20.
Fig. 6 shows an alternative cable conduit 300, which can be accommodated on
the conveying
device 1. Also, the cable conduit 300 is U-shaped. However, the side grid
walls of the cable
conduit 300 have a lower height than the grid bottom of the cable conduit 300
is wide. In
addition, the cable conduit 300 is inserted with its bottom into the holding
units 25 of the cable
conduit holder 20 and thus fixed at its bottom to the cable conduit holders
20.
Fig. 7 and Fig. 8 show the cable conduit 30, which is additionally equipped
with a cut-off bridge
35. The cut-off bridge 35 is preferably also formed in one piece. The cut-off
bridge 35 is
.. longitudinally inserted into the cable conduit 30, as shown in Fig. 7 and
Fig. 8, for example, to
separate signal lines from power lines or power cables from low power lines.
For example, the
power cables may conduct currents as regards voltages between 110 and 400V.
For example,
the low power lines may conduct currents as regards voltages up to 48V. Both
the power
cables and the low power lines may have at least one wire. However, other
separations of
.. cables or lines 34 (Fig. 4) are possible, such as electrical cables or
lines for a labeling machine
separated by the cut-off bridge from electrical cables or lines 34 (Fig. 4)
for an inspection
machine, etc.
The cut-off bridge 35 may be L-shaped and be provided in the bottom area with
a lug.
Preferably, the cut-off bridge 35 is formed so that the vertically extending
leg is aligned at right
angles to the bottom of the cable conduit 30 after installation. As shown in
Fig. 8, the lug
provided in the bottom prevents the cable conduit 30 from tipping to the right
in the direction of
the cable conduit holder 20 by application of a force. The leg of the L-shaped
cut-off bridge 35,
which extend parallel to the bottom of the cable conduit 30, prevents
analogously in
conjunction with the lug tilting to the left.
13
CA 03043357 2019-05-09
The cut-off bridge 35 can be fastened to the cable conduit 30 by a lug in the
bottom region.
The actual attachment is done by a "snap-in movement" in the longitudinal
direction or
alternatively in the transverse direction, depending on how the lug is
implemented.
In Fig. 8 is shown also a clip 37, which is mounted without tools below the
cable conduit 30,
that is, outside of the cable conduit 30, on one of the bars 31 of the grid.
The clip 37 may
receive or accommodate, for example, a pipe 37A for guiding a liquid or
gaseous medium, in
particular a belt lubrication hose, in which belt lubricant is guided. The
belt lubricant is needed
to reduce the coefficient of friction between the containers 5 as conveying
goods and the
conveying surface. The conveying surface can be realized as a conveyor belt
19, so that the
containers 5 move with the conveyor belt 19 in the conveying direction TR, as
previously
described with reference to Fig. 1.
As illustrated in Fig. 9, the clip 37 has first and second clip hooks 371,
372, each configured to
partially encompass one of the bars 31. Therefore, the clip hooks 371, 372 are
each open on
one side of their length. The clip hooks 371, 372 each form a hollow cylinder
segment. The clip
hooks 371, 372 are spaced from each other on the outer wall of another hollow
cylinder
segment, which forms a line accommodation or line receptacle 373. The pipe 37A
can also be
inserted without tools into the line receptacle 373. For this purpose, the
line receptacle 373 is
laterally open lengthwise.
In this way it is ensured that the liquid medium in the pipe 37A is kept
separate from current-
carrying lines, which is prescribed according to local regulations. In
addition, this type of
mounting allows better accessibility during initial mounting and / or later
access by an operator.
If several clips 37 are provided spaced apart along the bars 31 on the conduit
30 or 300, a pipe
37A can be very easily mounted to the conduit 30 or 300 and guided safely and
thus
advantageously on the cable conduit 30 or 300 along in particular the entire
conveying device

1. Compared to a fixed piping of the pipe 37A, the clips 37 significantly
simplify and speed up
the installation of the pipe 37A.
Since the clip 37 is formed in two parts in the region in which it is clipped
onto the cable
.. conduit 30 without tools, the clip 37 can be mounted so that it cannot slip
along the cable
conduit 30 or can be displaced. For this purpose, the clip hooks 371, 372 can
be mounted on
two sides of a bar 32 on a grid 31. As a result, defined spaces between the
mounting points of
the clip 37 can be realized, so that sagging of the pipe 37A is prevented.
This allows a fast,
clean and unambiguous installation of the pipe 37A. As required, however, the
clip 37 can also
be mounted between two bars 32 on a bar 31, if it is to be possible to move
the clip along the
bar 31.
Instead of a pipe 37A, the clip 37 may at least indirectly receive or
accommodate a cable or
another part which is to be guided on the cable conduit 30 or the cable
conduit 300.
Fig. 10 shows a clip 370 which, except for the dimensions of the clip hooks
371, 372 and the
line receptacle 373, is configured or designed in the same way as the clip 37
of Fig. 9. The clip
370 of Fig. 10 is longer in the longitudinal direction than the clip 37 of
Fig. 9. As a result, the
clip 370 has a greater stability and thus better function than the clip 37 of
Fig. 9.
Fig. 11 shows a variant of a clip 38 which can be mounted without tools at an
intersection of
two bars 31, 32 of the cable conduit 30 or 300. For this purpose, the clip 38
has a box-shaped
base body 380, on which on one side four projections 381, 382, 383, 384
protrude, between
which recesses 385, 386 are provided. The recesses 385, 386 are adapted in
shape to the
round bars 31, 32. In addition, the recesses 385, 386 are positioned crosswise
to one another.
Here, the recess 385 is provided between the four projections 381, 382, 383,
384, wherein the
recess 386 is positioned deeper in the base body 380 than the recess 385. As a
result, the clip
38 can advantageously be used at an "intersection area" of two bars 31, 32 of
the grid cable
conduit 30, 300. At a line receptacle 387, the pipe 37A can be accommodated
without tools.

Thus, a conveying device 1 for conveying containers 5 is shown, on which a C-
shaped railing
holder 15 is positioned, which can fix a railing 11, 12 in a force-locked
manner in two points.
On the railing holder 15, a cable conduit holder 20 is pluggable without
tools, wherein the cable
conduit holder 20 is fixed in form-lock by its form adapted to the geometry or
shape of the
.. railing holder 15. As a result, an orientation of the cable conduit holder
20 is performed at an
angle of 900 to the conveying device 1, in particular its conveyor belt. The
cable conduit holder
20 comprises due to the holding units 25 recesses or clearances for various
cable conduits 30,
300, so that each of the cable conduits 30, 300 is attachable without tools to
the respective
cable conduit holder 20. Moreover, at least one tool-free attachable clip in
the form of clips 37,
38, 380 can be mounted, if required, on the cable conduit 30, 300, as
described above.
The great advantage of the described cable conduit holder 20 and / or the clip
37, 38, 380 and
the conveying device 1 is that fitters during mounting of the conveying device
1 need only a
fraction of the time for the installation of the cable conduits 30, 300 and /
or the clip 37, 38, 380
.. than in a conventional mounting. This is clearly perceptible due to falling
costs for the putting
into service of the conveying device 1.
In a method for mounting the cable conduit 30 or 300 on the conveying device
1, accordingly,
at least one cable conduit holder 20 is mounted with its mounting unit first,
as described above.
Preferably, then the cable conduit 30 or 300 is mounted without tools in at
least two holding
units 25 of the cable conduit holder 20, as described above. However, it is
also possible that at
least one cable conduit holder 20 is already mounted on the cable conduit 30
or 300 before the
cable conduit holder 20 is mounted with its mounting unit 21 on the frame 10
of the conveying
device 1.
Fig. 12 shows a cable conduit holder 200 according to a second embodiment. The
cable
conduit holder 200 is largely carried out in the same manner as the cable
conduit holder 20
according to the preceding embodiment.
16
CA 03043357 2019-05-09
In contrast to the cable conduit holder 20 according to the preceding
embodiment, however,
the cable conduit holder 200 according to the present embodiment has lugs 255,
which are
positioned approximately parallel to the slot-shaped recesses 251, 258. The
lugs 255 are
positioned approximately in the middle of the slot-shaped recesses 251, 258.
The lugs 255
may be bent toward the cavities 252 along a bend line that is approximately
vertical to the slot-
shaped recesses 251, 258. As a result, the lugs 255 can also be bent
respectively in the
direction of the mounting unit 21 on the cable conduit holder 200.
Between a slot-shaped recess 251, 258 and a lug 255 perforations or openings
256 are
provided in the form of an oval opening. At the openings 256, more parts may
be fastened
such as cantilever arms, which otherwise would have to be circumvented
laboriously due to
the installation of the cable conduit 30. It is also conceivable to attach cut-
off bridge(s) 35 for a
cable conduit 30 to the openings 256, as shown in Fig. 6, instead of attaching
them to the
cable conduit 30 itself.
According to Fig. 13, a cable conduit 30 can also be mounted on the cable
conduit holder 200.
Likewise, mounting of a cable conduit 300 is possible on the cable conduit
holder 200, even if
this is not shown in the figures.
Thus, also in the second embodiment, the conveying device 1 is executed in the
same manner
as described above with respect to the first embodiment.
Fig. 14 to Fig. 16 show a cable conduit holder 2000 according to a third
embodiment. The
cable conduit holder 2000 is largely implemented in the same manner as the
cable conduit
holder 200 according to the previous embodiment.
However, unlike the cable conduit holder 200 according to the foregoing
embodiment, the
cable conduit holder 2000 according to the present embodiment has no cavities
252 at the end
of the slit-shaped recesses 251, 258. Instead, the slot-shaped recesses 251,
258 are
17
CA 03043357 2019-05-09
configured or designed as a straight running slot. In addition, no openings
254, 256 are
provided.
The cable conduit holder 2000 according to the present embodiment, however,
has lugs 257
which are positioned approximately parallel to the slot-shaped recesses 251,
258. The lugs
257 are positioned on the edge of the side of the cable conduit holder 2000,
which faces the
cable conduit 30 or 300 when the cable conduit 30 or 300 is mounted on the
cable conduit
holder 2000. Thus, the lugs 257 are positioned off-center of the slot-shaped
recesses 251,
258. The lugs 257 can be bent toward the cavities 252 along a bend line that
is positioned
approximately vertically to the slot-shaped recesses 251, 258. As a result,
the lugs 257 can
also be bent respectively in the direction of the mounting unit 21 on the
cable conduit holder
200.
According to Fig. 15 and Fig. 16, a cable conduit 30 can also be mounted on
the cable conduit
holder 2000. Likewise, it is possible to mount a cable conduit 300 on the
cable conduit holder
2000, even if this is not shown in the figures.
Thus, also in the third embodiment, the conveying device 1 is executed in the
same manner as
described above with respect to the first and second embodiments.
All off the previously described embodiments of the conveying device 1, the
cable conduit
holders 20, 200, 2000 and the method can be used individually or in all
possible combinations.
In particular, features may also be omitted unless they are described as
essential to the
invention. In addition, the features of all described embodiments can be
combined arbitrarily.
Moreover, in particular, the following modifications are conceivable.
The elements shown in the figures are depicted schematically and may differ in
the specific
implementation from the forms shown in the figures provided that the above-
described
functions are ensured.
18

The conveying device 1 does not necessarily have a conveyor belt.
Alternatively or
additionally, the conveying device 1 may comprise a carousel with which the
containers 5 can
be conveyed on a circular path. Also on the carousel the cable conduit holders
20, 200, 2000
are easy to install, since the different distances to the conveying device 1
can be covered, as
they occur for example on curves.
The conveying plane of the conveying device 1 does not have to be positioned
horizontally.
The conveying plane can therefore also be positioned inclined to the
horizontal.
Depending on the availability, various cable conduit holders 20, 200, 2000 can
be used in the
conveying device 1 for mounting one of the cable conduits 30, 3000.
It is very easy to adapt the position of the slot-shaped recesses 251, 258 or
lugs 253, 255, 257
as needed to the cable conduits 30, 300 which are to be mounted. Thus, it can
be reacted
flexibly to the existing local conditions for mounting the conveying device 1.
It is also possible to provide at least one of the slot-shaped recesses 251,
258 with a cavity
252 in the cable conduit holders 20, 200, 2000 as needed, as shown and
described for the
cable conduit holders 20, 200. In addition, at least one of the slot-shaped
recesses 251, 258
without cavity 252 may also be provided on the same cable conduit holder 20,
200, 2000, as
shown and described for the cable conduit holders 20, 200.
In addition, it is conceivable to combine as desired at least two different
forms of the shapes
shown for the lugs 253, 255, 257 on the cable conduit holders 20, 200, 2000.
