Description

fig 1

The invention relates to the fishing industry, and in particular to methods of oriented feeding of fish, mainly flounder, to cutting tools in a fish processing machine, and also to devices for their implementation, and can be used in the processing of flounder for carcass, of all types and sizes without prior sorting .

Known methods and devices for processing flat fish are based on feeding and orienting them to the processing tools strictly in a horizontal plane according to the principle of a flow line or a circular process.

Their common disadvantage is the need for large work areas. The use of known fish processing machines for flounder is limited on board.

There is a method of orienting fish in a longitudinal position for decapitation, according to which the laid-down fish moves until the outer part of the body of the fish reaches the stop, and the abdominal fin rotates 90 ° from the bottom of the fish in the cutting direction and in this position it is used to limit the longitudinal movement of fish.

The device for carrying out the method includes a device for orienting fish in contact with the cutting plane and a guiding edge extending in the cutting direction, the inlet end of the edge has an arcuate shape, and the output end is lagged at an angle from the cutting plane.

However, this method and device cannot be used directly for flat fish having the shape of the dorsal and ventral fins, other than fish having a circle or oval in cross section.

Also, this method is not intended to accurately feed the fish under the oblique cut to simultaneously remove the head and abdomen with the viscera, since the orienting device provides the cut directly behind the pectoral fin.

The closest analogue is a device for feeding and orienting fish in fish processing machines having a transport unit, with which the fish is transported head-down down along the orienting element to which the fish is adjacent with its snout and from the initial position relative to the snout is oriented depending on the length of the head to transporting it piece by piece past the head-cutting knives, the orienting element includes a head support with a pivotally connected to it and serving to determine the size of the fish the plate is connected to the sliding guides for the fish, the conveyor includes loading tapes, and behind the head cutters there is a means for turning the fish from a vertical position to a floating one.

The disadvantages of this device is the need to use additional actuators for

5 transferring fish to a floating state.

The aim of the invention is to provide a more accurate orientation of fish on an economical cut while cutting off the head and abdomen with the insides, and

0 is also a compact device.

The goal is achieved in that in a method of oriented feeding of fish to the cutting tools, mainly flat, by fixing the fish and

5, by moving it head downward with the possibility of deflection using a guide interacting with the head part, the fish is fixed in the tail part in a freely suspended position with the abdomen forward in the direction of movement, and the fish are deflected before crossing its cutting line under its own weight.

Goal Also Achieved

5 in that in a device for implementing the method, comprising a transporting body with elements for fixing the fish and moving its head down and orienting the device, the latter consists of a set of V-shaped gutters arranged in series along the transporting body and the base of the gutter placed in front of the cutting tool for cutting the head, is installed relative to the working branch of the transporting body with elements for fixing at a distance that ensures the inclination of the fish when cutting off the head

0 and abdomen

Also, the transporting body is made in the form of an endless carrier chain, and the fixing elements are in the form of pointed L-shaped pointed rods attached to the chain.

Also, the chute located behind the cutting tool for cutting the head is set at an acute angle to the base of the previous chute.

On Fig, 1 schematically shows a device, General view, side view; in FIG. 2 is a cross-sectional view of fish feed channels

The device for oriented feeding fish mainly flat to the cutting tools consists of a transporting body 1 with elements 2 for fixing the fish and moving it head down, an orienting device, a circular knife 3 for removing the head, along with the abdomen and entrails, and a cutter 4 for removing the side fins.

The transporting body 1 is made in the form of an endless carrier chain with elements 2 evenly spaced on it for fixing - in the form of pointed rods of a L-shaped form fixed on it, simultaneously playing the role of a chain axis.

The transporting body 1 is mounted on a frame 5 made of a channel and located horizontally, on a drive 6 carrier 6 and a tensioning 7 sprockets.

The orienting element is made in the form of a set of grooves 8, 9, 10 of a V-shape, sequentially located along the transporting body 1. The sides of the grooves 8. 9, 10 are located at an acute angle equal to the natural bevel of the largest abdominal and dorsal portions of the processed fish.

The base of the chute 8, which is placed in front of the circular knife 3, is installed relative to the working branch of the transporting body 1 with elements 2 for fixing the fish at a distance that allows the fish to tilt when cutting off the head and abdomen with the insides and corresponds to the minimum size of the fish being processed.

The groove 9 is mounted directly behind the circular knife 3 at an acute angle to the base of the previous groove 8. At its base 9, a slot is made for the cutter 4, which allows the side fin to be removed.

The groove 10 is installed at an acute angle to the horizons and has a slot for cutter 4.

A circular knife 3 for removing the head with the abdomen and viscera is mounted on the output end of the groove 8 and to a height from its base equal to the length of the head of the minimally processed fish. Disk knife 3 is mounted on an electric motor 11.

The mounting height of the circular knife 3 depends on the raw material and is readjusted by turning the lever 12.

The drive 13 of the device consists of an electric motor 14 and a gearbox 15, which simultaneously performs the role of a bearing

node for the drive sprocket 6 In the area of the tension sprocket 7 there is a tie table 16 with a device 17 for holding the tail of the fish when 5 piercing it with a pointed rod 2

The device is equipped with a set of gutters 18 for removing waste and processed flounder from it. All device nodes are closed

10 casing 19.

The device operates as follows.

Fish, preferably flounder, is delivered individually to the loading barrel 16 in

5, the lying position of the abdominal side-th down and tail to the side of the device 17 dp holding the tail of the fish

The pointed rod of the L-shaped form approaches the fish from the bottom with the tip up and

0 imposes it in the tail region. The transporting body 1 raises the fish from the loading table 16 and moves it in a suspended position, head down on the rod 2 to the groove 8 for orientation of the fish

5 for simultaneous cutting off of her head and abdominal part with viscera. Once in the chute 8, the fish head slides along the base along its lateral sides and deviates from its original

0 vertical position at an angle corresponding to the most economical cut of it. Since the distance between the working branch of the transporting organ 1 and the base of the trough 8 is constant for each type of fish 5, fish of different sizes when moving along the trough 8 to its end have a different angle of inclination to the cut plane. The fish is pulled to the intersection of the cutting line with its circular knife

0 3. The severed head and abdominal part with entrails are diverted along the trench 18. The headless fish moves behind the tail along the inclined trench 9 by the ventral fin at its base and at the exit

At its 5th end, the spine bends naturally in a vertical plane, the fin straightens and is directed to the milling cutter 4. As the ps milling cutter moves 4, the fish can move

5 carcasses up and down, is copied by its abdominal fin and thereby ensures its complete removal with a milling cutter 4. After the fish leaves the chute 9, it receives a suspended position on the rod 2 and bends around an asterisk 7, moves with the opposite fin along the base of the inclined chute 10, where the second fin is separated by the lower cutter 4. The side fin is separated in the same way as described above.

Further, the fish takes up a suspended position on the rod 2 and moves along the lower branch of the transporting organ 1 to the circular knife 3 from the opposite side. A circular knife 3 cuts the carcass from the tail below rod 2. The carcass enters the receiving chute and is removed from the device.

The rod 2 with the tail of the fish approaches the fork-shaped puller, where the tail is removed from it and disposed of via the chute 19. Then, the rod 2 is brought to the loading table 16 to capture a new fish specimen.

The proposed method of oriented feeding flat fish to cutting tools and a device for its implementation provide accurate orientation and feeding due to:

providing the possibility of fixing flat fish in a suspended state and the possibility of its deflection at different necessary angles of the vertical plane when moving along the gutters using its structure and the degree of bending of its spinal bone;

using a set of V-shaped gutters with a bevel angle equal to the natural bevel of the fish
