The invention concerns a device for conveyiny and
delivering fish in controllable amounts and distribution.
In a conveying device which can be used as a feeding
conveyor for fish processing machines (see ~erman Patent
27 03 061) the ~ish are guided to the processing machine by
means of a bucket band from an inclined reservoir via a
lifting arrangement~ In this device the working run faces
the processing machine and is so guided at the end of the
lifting arrangement over the same that at the deflecting
position the buckets are charged with a rotating acceleration
which ejects their contents. This conveying ~evice cannot
be used universally because the space between the lifting
run and the delivery station is very limited since the latter
is determined by the reversing station. Consequently an
interim conveyor must be added to the pxocessing machines
which need more space preferably upstream thereof in order
to achieve a bridging between the delivery station of the
conveying device and the feeding position of the processing
machine. Furthermore it has proved to be desadvantageous
that the conveying sequence produced by this device occurs
discontinuously corresponding to each sudden release of the
bucket contents. The consequence of this is that impediments
occur in the takeover of the fish by the following processing
machine.
It is an essential object of the invention to
suggest a conveying device which can be used as a universal
component part in fish processing machines. A further object
is to provide for a conveying device capable of supplying the
fish to a processing machine in a continuous conveying
current in single layers as well as adjustably with regard
to the amount and distribution of fish per time unit.
According to the present invention there is provided
a device for conveying and delivering fish in control-
lable amounts and distribution, the device comprising liftiny
conveyor means provided with chamber means guided endlessly
about de~lecting elements and including an essentially

horizontally pxojecting upper section in the area of
delivery station means, and the device fuxther comprising
fish supplying container means in th~ region of supplying
stati.on means and provided with an inclined bottom, wherein
the chamber means are formed essentially by entraining webs
moving along a path of the conveyor means, wherein the
delivery station means are arranged in the returning run of
the projecting upper section, and wherein in the region of
the deflecting elements positioned in the projecting upper
section cover means are provided equidistant to the path
of the outer edges of the entraining webs, which cover means
are led up until the delivery station means, said cover
means having an edge facing the delivery station means,said
edge being slanted with respect to the conveying direction
of the conveyor means.
The advantages thus achieved lie especially in
that an adjustment and adaptation of the delivery station
to various circumstances and requirements can be achieved
merely by the form and configuration of the cover which is
positioned in the -
`$ /
region of the reve.rsing ~tation oi. the conveying belt in the pro-
jecting upper section of the conveying device resp. of the edge
of the covax faclng the delivery station. Furthermore a con-
tinuo~s single release of the ~ish is .safeguarded by the fact that
the 1sh, dependellt on ~he e~fec~ o~ gravi~y come to xest on the
inner surface of the cover in ~he region o~ the mentioned de~lect~
ing re~p. rever~ing station and t~lereby ~o foxm a single layer
distribution which is ~hen ~aintained during the following pushing
transport.
Apart from the possibility o~ control.~ing the sp~ed for the
movem~n~ of the conveying belt. carrying ~he entraining webs and
in order to achieve a further adjus~ability of the device the
ent.raining webs may have a firs~ web por~ion ex~ending upwardly
essentially vertically to the conv~ying direc~ion of ~he con-
veyor, which first web portion in the region of the outer part
of the chambers carrie~ a second web portion bevelled in the
conveying direction, this second web portion being provided on
its conveying s~de with a rail extendlng along the web and able
to be fixed adjustably transverse to the web. Thereby the conveying
volume of the single conveying chambers defined by the entraining
w~bs is adjustable without the height of the entraining w~-bs
measur~d Eor a narrow gap with respect t~ the cover havlng to
be cha~ged.
In order to influence the la~eral distribution o~ the f ish
the edge of the cover facing the delivery station can be arranged
to be adjus~able in its gradient.

DESCRIPTION OF THE P~EFERRED EMBODIMENTS
An upwaxdly extending machine frame essentially co~prises
two side ele~ents 1 and 2 with a gallow~-like projecting upper
section, which side parts are arranged parallel to each other
on a sultable base frame 3. In this machine frame there are
arranged xeversi~g resp. delecting stations 5 and 6 as well
as 7~8 and 9/10 for the guiding of an endlessly running link
conveyor belt 11 driven in a controllable mannerl which
stations are merely shown rather generally. The link conveyQr
belt 11 is provided with entraining webs 12 which are mounted
on angle projection~ 13 of the belt 11 and each comprise a
flrst vertically extending web portion 14 and a second web
portion 15 e~tending therefrom and bevelled in the conveying
direction. ~ small rail 16 extending in the longitudinal
~,?~
~z~
direction of ~he web 12 is attached to the bevelled web
portion 15 on thP conveying side and can ~e adjusted with resard
to its distance above the conveying belt 11 by means of not-
shown elonga~ed holes. ~ fish supply.~ng con~alner 17
S connecting bokh side parts 1 and 2 ln the manner of a bridge
is positioned near the base frame 3 on ~he side turn~d away
from the pro~ec~ing upper section ~ and has a bot~om 18. The
latter can be m~de to oscillate by means of a vlbrator 20, is
arranged inclined in the direction of a path 19 of the
~0 entraini~g webs 12 and ends ~lmost at the path 19. A cover 21
is po~ltioned in the region of the reversing station G in
the projecting upper section 4 equldistant at a small distance
from the path 19 of the entraining webs 12 which cover 21 is
guided around to a returning run 22 of the projecting upper
section 4 and ends in front of the de~lection stations 7/8,
leaving free a delivery station 23. ~n edge 24 pointing
towards the latter is formed by a sliding plake 26 which can
be swivelled around a coupling 25 near the side element 1
and is adjustable by means o~ an elongated hole, which plate
can be firmly set by means of a clamping device 27 so that the
gradient of the edge 24 is variable in respect of the
conveying direction.
The mode of operation of the appara~us ls ~he following:
With the support of the vibration of the bottom 18 the
~ish supplied to the store tank 17 reach the path l9 of the
entraining web~ 12 and are entrained resp. conveyed by these.
The number of fish conveyed by each entraining web 12 adjusts
itself acGording to the arrangement of the rail 16, i~e. its
~`i 5
distance fxom the conveyor bel~ 11. The ish are thus pushed
on to the level of the projecting upper section 4 and run
under the covex 21. Xn the region of ~he reversing station
6 the fish are released from the link con~eying belt 11 and
the entraining web 12 by the effe~t of gr~vity and slide by
movin~ ln fron~ of the web 12 on the inner surface of the
cover 21, spreading th~mselves in a slngle layer. In the
further course this layer of the fish is enyaged in a pushing
manner by the entraining web 12 which has in the meantime
arrived above and it is led to the delivery station 23~ The
distribution of the fish is effec~ed by~means of the adjust-
able sliding plate 26. The edge 24 of the sliding plate ~6
whlch faces the delivery s~ation 23 can be adjusted with
respect to its direction in accordance with the speed of
the entraining webs 12 such that a delivery of the fish
essentially uniform over the width of the delivery station
23 can be achieYed.
The coupling 25 of the sliding plate 26 is not limited
-to the described positionO It can also be arranged in the
region between the side el~nents 1 and 2, preferably in the
middle thereof, a uniform influence on the marginal areas of
the delivery station 23 beiny obtainable when i~ is adjusted.
