The invention relates to an insertion device for booking machines,
comprising insertion funnels for manually insertab:Le record carriers, the
said funnels being laterally displaceable on guide rails over the printing
width after the release of a lock.
The insertion device for booking machines are known to be formed
from two separate slidable funnel halves, so that :record carriers of
different width can be inserted. The two funnel halves are journal]ed on
guide rails above the printing roller of a series printing device whereon
they can be locked after adjustment of the form wid~h. The insertion device
then projects above the booking machine, thus disturbing the overall
appearance. This also hampers the insertion of a record carrier by the
operator.
The invention has for its object to construct the insertion device
such that the insertion funnel projects only slightly from the booking
machine and that the insertion of the record carrier is substantially
facilitated, accurately straight insertion and ejection being possible
without special devices being required.
According to the present invention, then, there is provided an
insertion device for booking machines, comprising two upper input funnels
for manually insertable record carriers) the said funnels being mounted to
be adjacent above a printing platen and being laterally displaceable on
guide rails over the full printing width, and two further adjacently arranged
lower funnels which are mounted underneath the printing platen and are also
laterally adjustable, characterized in that locking devices are provided

whereby the upper funnels can be coupled to the associated lower funnels for
lateral adjustment together and whereby the funnels can be locked in the
positions to which they are adjusted.
Because the intake and ejection devices of ~his insertion device,
consisting of various parts, are situated below the printing plane of the
printing device, it may occur that, after the ejection of the record carrier,
the record carrier becomes stuck above the ejection device within the reach
of the printing device, if the record carrier is not immediately removed
from the insertion device.
In accordance with a further embodiment according to the invention,
therefore, an additional ejection device is provided in one of the funnel
halves situated above the printing roller, this additional device serving
to maintain the ejected record carrier in a position above the printing area,
so that vertical ejection of the record carrier is ensured.
~le invention will be described in detail hereina-fter with
reference to the drawings.
Fig. 1 is a front view of the complete insertion device according
to the invention.
Fig. 2 is a side elevation of the device shown in Fig. 1.
Fig. 3 is a side elevation of the additional ejec~ion device.
The complete insertion device consists of two funnel halves 1 and
2 which are provided above the printing roller 5, and lower funnel halves
3 and 4 which are situated underneath the printing roller 5. The two lower
funnel halves 3 and 4 are accommodated in a common housing 9 wherein they
are laterally displaceable. Each of the two upper funnel halves 1 and 2
is slidable on a guide rail 6 by way of the rollers 7 and 8. The housing 9

and 4 is sliclable on a rail 10. The two lower fllnnel halves 3
and ~I can t`ur-~hermore be la-terally displaced over gulde ralls
11 and 12. The hollsing ~ of` the lower funnel halves 3 and 4
accommodates the transport rollers 13 and 14 for the insertion
and the ejection of the record carrier, and also the printing
- and reading devices. The upper guide rail 6 and the lower rail
10 are secured to the housing of the booking machine in a
manner not shown. On -the upper guide rail 6 -there is provided
a plate 15 which extends over the entire ~orm wid-th and which
is provided with teeth on the fron side for locking the funnel
- halves 1 and 2~ The lower funnel halves 3 and 4 can be arrested
on a shaft 26 which is secured ln the housing 9.
In each of the upper fllnnel halves 1 and 2 a
loclcing pawl 17 is provided which is ~journalled on a shaft 18
1~ and which is also provided with -teeth on the end 1~ for loclcing
purposes. The spring 20 keeps the pawl 17 in the locking posi~
tion. Via a lever 21 and a connecting rod 22, the relevant
funnel half 1 or 2 can be manually slid in the lateral direc-
-tion. As a result, the upper funnel halves 1 and 2 can be
aligned with respect to the associated lower funnel halves 3
and 4; this is necessary, for example, during assembly.
On the outer edge of each lower funnel half 3
and 4 a locklng pawl 23 is provided, one end 24 of which is
situated below the opening of a coupling element 27, the other
end 25 thereof being provided with teeth which engage the
teeth of the shaft 26. ~ike for the upper funnelhalves 1 and
2 this locking position is maintained by a spring 2~.
On each upper funnel half 1 and 2 there is
provided a locking button 30 and 31 which can be moved down-
wards on both sides. A coupling pin 32, 33 is connected to the
upper portion of these but-tons. The lower end of the coupling
pin 32 as well as 33 is accornmodated in a bush 34. The reset
Pl{~.71~ _ l 6~ c
105'~3~2 3-7--l975
sprlng 35 bears against the busll 34, and kee~ps the button 30
in tlle starting position.
The adjustment of the form width is effec-ted by
means of the locking buttons 30 and 31. If one of these buttons
is pressed downwards, the end of the coupling pin 32 engages,
viathe associated coupling element 27, 28, the snd 24 of the
pawl 23, thus un~ocking -this pawl against -the force of the
spring 29. Before the end of the coupling pin 32 ~ 33 engages
the pawl 23, but after this pin has been guided into -the ele-
ments 27, 28, the obligue side 36 of the button 30, 31 slides
over the end 37 of the pawl 17, thlls turning this pawl against
the force of the spring 20. As a result, first the locking of
the upper funnel half 1, 2 and subsequently the locking of the
lower ~unnel half 3, 4 is effected. In this operating position
f the 'loclcing buttons 30, 31, the upper funnel half 1, 2 and
the associate'd lower funnel half 3, 4 can be adjusted in the
lateral direction on the guide rails 6, 11 and 12 in dependence
of the~form. When the locking buttons are allowed to snap
upwards again, the two pawls 17 and 23 engage each other again
by way of their teeth.
In one of the two upper f`unnel halves, in the
left-hand'funnel hal~ q in the relevant example, moreover, an
ejection device is provided which is'slightly wider for this
reason. In a housing 38 there is provided an electric rnotor
' 39 which drives a shaft 41 via a drive 40. On this shaft 41
two bearing houses 42 and 43 are journalled to be rotatable;
therebetween gearwheels 44, 45 are provided which are rigidly
connected to the drive shaft 41. These gearwheels 44 and 45
are linked to the two transport rollers 46 and 1~7 which are
journalled in the bearing housings and-which can rotate about
the shaft 41 together with these housings. In the centre
between the two bearing housings 1l~ and 1l3 on the shaft 41
-~ PI~ 163 C
10~3~Z ` 3~7~.l975
there is provided a brake ll8, on the prolongation ~l~ of which
a trip 50 is pivotably journalled. This trip 50 is also pivo-
tably cormected to the two bearing housings 42 and 1~3,
1~hen the shaf-t 4l is driven in the direction of
the arrow (Fig. 3) 9 the bralce 48 is talcen along so ~ar in the
direction of the guide slot 51 for the record carrier,and hence
also the trip 50 and the bearing housings ~l2 and 43, that the
two transport rollers 46 and 47 contact the record carrier
and eject the record carrier in the upwards direction in co-
operation with the counter roller 52. The pivotable journalling
of the housings-42 and 43 ensures that the two transport
rollers 46 and l~7 always contact -the record carrier at the
same pressure. Moreover, it is achieved that the two rollers
~6 and 1~7 0xert a wedging effect on the counter roller 52
which each time acts against the ejection direction, and hence
agains-t the direction of rotation of the transport rollers 46
and 47. ~ue to this wedging ef~ect it is achieved that the
record carrier present between the transport rollers 46 and
47 and the counter roller 52 can follow the direction of the
rotation of the transport rollers and is ultimately e~ected.
. The contact lever 53 of a microswitch 54 pro-
jects into the guide s:Lot 51. This microswitch is operated by
the record carrier present in the slot 51. Because of the
presence of this contact lever 53 and by utilizing a corres-
25~ ponding programming, it is achieved that the electric motor
39 of the ejection device is switches on only when the record
carrier is moved in the ejection direction by the transport
rollers 13 and 14. A~-ter depar-ture from the transport rollers
. 13 and 14, the record carrier is moved .further only by the
transport roller 46 anc1 47, until -the lower edge of the record
carrier is above these transport rollers 46 and 47. In this
case the elect:ric motor remains switched on for as long as the

for as lon~ as the record carrler has not been removed Irom
the :Lnser-tion device or1 if this record carrler need not be
reinserted (if so programmed), i-t is maintained in the position
above the printing roller 5 by the continuously rotating
rollers 46 and 47.
The fact that the transport rollers 46 and 47
are arranged to be pivotable enables the record carrier -to be
accurately vertically ejec-ted. Irregularities of the record
carrier have no effect because, due to the wedging ef~ect, the
two transport rollers 46 and 47 adapt themsel~es independent
of eachother -to the circumstances at the contact area with the
record carrier. ~ue to the trip-like jo1lrnalling of the trans-
port rollers 46 and 47, not only irregularlties in the record
carrler but also differences and tolerances in the insertion
fu~nel and differences in the parallelity o~ the counter roller
52 with respect to the bearings on the shaft are compensated
for. The e~jection of the record carrier is thus smoothly ef~ected.
~ After the switching off of t~e electric motor
39, the brake 48 is returned to the rest position shown in
~ig. 3 by the spring 55.
