Description
36~
The presPnt invention concerns a device for conveying fish head end first through a fish-processing machine.
Such a device can be taken from German Letters Patent 1 154 913. This known construction comprises a belt with grippers, the belt being arranged above the fish path of a fish processing machine and having the task of conveying the fish through this machine for the purpose of being processed. The grippers are so formed ~hat the conveying engagement or grip takes place in the region of the back so that the flanks of the fish remain accessible for the guiding elements and the processing operations which, e.g. enables an optimal separation of the ribs in respect of the yield by precise guiding of each fish.
The task upon which that construction was based in view of the constructions known at that time is also directed to improving the conveying engagement in order to guarantee a safe entrainment of the fish during the __ operation of the tools. This goal is reached due to the flexibility of the conveyor effecting an improved adapt~tion to the back contour of the fish and thus enabling a better transmission of the conveying forces. It becomes apparent, how~ver, that, especially wi~h spindle-shaped fish, e.g.
S mackerel or tuna, the course of the filleting cuts in the tail region can not be contro].led definitely. The reason for this is that the flexibility of the conveyor achieved is not sufficient to guide the thin tail part of the fish as well, so that there is not sufficient support against the efficient cutting forces of the filleting tools in this part. The consequence of this is the observed extreme dependence of the cuttin~ result on the condition of the cutting tools.
In txying to remedy this deficiency the solution upon which German Patent 28 04 232 is based was found. The back part of the fish 1s made accessible by the arrangement of two wedge profile belts lying adjacent to each other and each carrying one half of the grippers with no change in the conveying efect occurring, so that additional guide elements could be provided to cope with ~he mentioned problems.
This functionally satisfactory concept is, however, very costly and therefore uneconomical. Furthermore, although it i5 possible to use tools which are effective from above, it does not serve to facilitate the necessary cutting sequence slnce e.g. the separation of the back part may be performed quite easily from the abdominal side of the flsho :~8~L3~i It is therefore an object of the invention to suggest an improved device of the type described above in respect of *he outlined disadvantages inherent in ~he con-veying device shown in the first-mentioned prior art. It is another object of the invention to reduce the expenditure for such a device to a tolerable extent.
It is a further essential object of the invention to enable a safe supporting of the back part of the fish and thus the guiding of the same over the whole length.
According to the present invention, there is provided a device for conveying fish defining a head end, a tail end, a back region and a plane or symmetry, with said head end leading through a fish processing machine, said device comprising endless conveying means, driving pulley means and deflection pulley means, said conveying means running in a running plane about said driving pulley means and said deflection pulley means in said plane of symmetry of the fish to be processed, carrying prism-shaped entraining means adapted to engage said fish in said back region, and defining a working run which is resiliently supported by presser means distributed over the length of said working run, wherein said conveying means are formed by a conveying organ means being positively driven and arranged highly flexible in said running plane.
The advantages thus obtained lie particularly in that due to the positive driving of the conveying organ its longitudinal stress can be adjusted taking exclusively the desired flexibility into account, iOe. it can be minimised so that an ideal adjustment of the entraining elements to the back contour of the fish takes ~lace.
_ _ _ _ i, =
3~5i In order to avoid an ~Ipalrment of the flexibility by the driving torque resulting rom the frictional and cut ting forces the working run or strand of the conveying organ may be driven in a pushiny manner which may be effected by the driving wheel which provides the driving being arranged on the intake side of the working run or strand of the conveying organ.
In an especially advan-tageous embodiment of the device according to the invention the conveying organ is formed as a link chain composed of chain members endlessly con~
nected to each other which can also be made of highly wear-resistant and tough synthetic material ~s can the link pins which join them.
The prism-shaped entraining elements which conveyin~ly engage the fish may advantageously either be connected detachably to the chain links or manufactured integrally with these~
In order to obtain an extreme capacity of resistance to we2r a toothed belt may expediently be used as the convey~ng orc3an, which belt may be provided with prismatic entraining elements on its outer sur~ace.
BRIEF DESCRIPTION OF THE DRAWINGS
Other and further objects of the present invention will be apparent from the following description and claims and are illustrated in the accompanyiny drawings which by way of illustration schematically show preferred embodiments o~ the present invention and the principles thereo~ and what now are considered to be the best modes contemplated or applying these principles. Other embodiments o~ -the invention embodying the same or equivalent principles may he used and structural changes may be made as desired by those skilled in the ar without departing from the present invention and the scope of the appended claims.
In the drawings;-Fig. 1 shows an axonometrical representation ofa total view of the conveyor according to the present .invention, Fig. 2 shows a partial view of the conveying organ formed as a link chain, and Fig. 3 shows a partial view of the conveying organ formed as a toothed-belt.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
In a not-shown frame of a fish-processing machine, e.g.
a filleting machine, a conveyor 4 is arranged above a fish path 1 and rotating about a deflection pulley, roller or wheel 2 and a dxive pulley, roller or wheel 3 in a vertical plane. The drive pulley 3 is driven by means of a suitable driving mechanism 5 in the direction of the arrow 6~ and with the conveyor according to Fig. 1, positively transmits the driving torque via pins 7 arranged on the periphery of the drive pulley 3 to the conveying organ formed by a plate link chain 8. This conveying organ is built up from single chain members 9 connected to each other by means of link pins 10, each of the chain members 9 carrying on its outer 3~
surface an entra~ning element 11 wi-th a prisma-tic recess 12 on th~ side coming into contact wlth the fish. A working run or slack 13 of the conveying organ is held down resili-ently against the fish path 1 by spring-biassed presser rollers 14. For the sake of clear representation only one of these presser rollers forming a compact chain is repro-duced schemat~cally. The conveying organ is guided laterally by guide elements 15 in the region of the working run 13 and supported in height above the fish path 1 in such a way that there will always be a minimum distance to the latter.
~ ccording to Fig. 3 a toothed belt 16 is used as a conveying organ, which belt serves as a carrier band for the entraining elements 11. In this case the deflection pulley 2 and the drive pulley 3 are provided with corres-ponding proiles on their periphery.
The working function of the device according ~o the invention i9 as follows:
Fish 17 su:itably fed to the fish path 1 head first come into contact in the region o their back with the entrain-ing elements 11 of the working run 13 of the conveyor 4 and are led past processing tools (not shawn) arranged along the fish path 1. The fish 17 i~ guided in the fish path 1 in such a way that its backbone runs almost parallel to it. The guiding o the conveying organ which may be performed to change in height enables the accordingly necessary adjustmen-'_ to the back contour of the ~ish, the resiliently downward urging presser rollers 14 guaranteeing 3~i a defined conveying pressure. Due to ~he high flexibility o:E -the conveying organ which is a result oE its construc tion and which, due to the thrusting or pushing effect of the drive, is also maintained independent of its charge, each fish is conveyingly engaged along its whole length and thus guided simultaneously. The disclosed characteristics make such a delicate adjustment possible so that an extremely careful manipulation of the fish and safe transport is made possible.
