(54) DEVICE FOR DOWNLOADING SMOKED FISH INTO MACHINE

one

The invention relates to the fish processing industry, and more specifically to equipment for placing fish in cans and can be used in machines for a series of laying in the production of canned sprats in oil.

A known machine for cutting and laying smoked fish in cans, containing, and a transporting body, mechanisms for cutting heads and tail fins in fish, a device for forming portions of fish in single-layer rows, pushers for filling fish carcasses into a device and device for crimping and laying p Dov carcasses in banks 1.

However, these machines are loaded manually, so productivity is low.

The closest to the invention to the technical essence and the achieved result is a device for loading smoked fish into a fish former forcing a fish for a machine for cutting and placing smoked fish in cans containing chain feed conveyors for feeding fish rods, a mechanism for cutting heads, a collecting cassette with cells and a pusher for issuing carcasses

fish from the cassette. In this machine, the fish, strung on rods, is fed to the receiving conveyor to cut the heads, then, by the action of its own weight, it is loaded onto the feeding conveyor, which feeds the fish carcass to the former of the machine 2.

However, due to the fact that there is an incomplete amount of fish on the rods, as it acquires a brittle consistency during the heat treatment process and individual carcasses are cut off from the rod, and the remaining ones. Fish take different positions, not all cassette cells are filled with carcasses. However, it is possible to report the carcass to the empty cells of the cassettes only at the maximum speed of the machine, which leads to a decrease in the productivity of the machine to a value less than with manual packing. All this leads to a decrease in the efficiency of using the machine for placing smoked fish in cans. To free the female workers from manually placing the fish in the cans is a real need, because the labor of female fish workers is inefficient.

monotonous and debilitating, leading to finger disease.

The purpose of the invention is to ensure that fish are loaded into the cassette cells without gaps and to increase productivity by eliminating fish.

The goal is achieved by the fact that the device for loading smoked fish into a laying machine, including a chain conveyor for feeding bars with fish, a mechanism for cutting heads, an accumulator cassette with cells and a pusher for discharging fish carcasses from the cartridge, has an additional chain conveyor for feeding bars with fish , an elastic belt conveyor located underneath and a closed drive chain with a lead ma, the upper branch of which is located above the elastic belt conveyor, and at the same level as the last one under the main chain link When mounted, the platforms are mounted side-mounted on horizontal axes and can be rotated by means of solenoids, while the accumulator cassette is pivotally fixed under the platforms at an angle to the horizontal plane with the possibility of lifting and lowering movement by means of a cam drive with leads, and in each cell of the cassette are mounted contacts connected to the solenoid, and a spring-loaded plate for closing the contacts.

FIG. 1 shows a device for loading smoked fish into a laying machine, side view in section; in fig. 2 - the same, top view; in fig. 3 - the same, front view.

The device contains a loading chain conveyor 1, a reporting chain conveyor 2, made in the form of chains carrying rods 3c of smoked strung together, a mechanism for cutting heads 4 installed on the loading and reporting chain conveyors 1 and 2, a conveyor 5 with elastic tape, leashes 6 mounted on a closed drive circuit 7. In the same plane with the upper branch of the conveyor 5 are located in a row of pad 8, made in the form of rectangles and with a large side attached to an axis 9, rigidly connected at one end to the curvature 10, which is hingedly connected to the rod 11 of the solenoid 12 containing the winding 13 and the core 14.

Under the pads 8, a cumulative cassette 15 with cells in an amount equal to the number of sites 8 is installed pivotally and at an angle to the horizontal plane, and their number is equal to the maximum number of fish stacked in cans (for example, 22). In each cell of the accumulation cassette 15, a plate spring 16 is fixed at one end, and contacts 17 connected to the winding of the solenoid 12 are mounted inside the cell. For a clear hit of fish in the cell of the accumulation cassette, 18 partitions are mounted between adjacent solenoids 12. For pushing the accumulation cassette 15 carcasses of fish in the shaper-laying machine device, the device has a pusher 19.

The drive to the chain 7 with the drivers 6 and the cam 20 for raising and lowering the accumulation cassette 15 is made according to the following kinematic chain: from the electric motor 21 through the gearbox 22, the electromagnetic clutch 23, a pair of bevel gears 24, one of which is fixed to the shaft having on the upper end chain sprocket 7, and at the other end a tapered pinch 25 which engages with a similar gear mounted on a shaft with an integrated electromagnetic clutch 26. At the end of this shaft there is a bevel gear 27 fixed, kinematically connected with another pinion mounted on the cam 20. The electrical circuit (FIG. 1) includes a switch 28, contacts 29, contact strips 30 and contacts (a, b, c, d ... e, rf) and a, b, c , d ... e, p) respectively, mounted on the ends of the rods 11.

The device works as follows.

The boot chain conveyor 1 delivers smoked fish strung on rods 3 to the mechanism 4 for cutting heads made, for example, in the form of scissors. Cut off by the mechanism 4 fish whistlers from a chain conveyor 1 fall between partitions 18

0 which guide it into the cells of the accumulation cassette 15. The fish carcass at the bottom of the cell presses the plate spring 16, which closes the contacts 17. The current flows into the winding 13 of the solenoid 12, the core 14 rises up and through the rod 11 the crank 10 rotates the axis 9 with the platform 8 fixed on it, which is placed in a horizontal position, thus overlapping the space above this cell.

However, during the process of cooking and smoking from the rods, part of the fish is cut off due to the weakening of the strength of the fish carcass. Therefore, it is necessary to fill the empty cells of the accumulation cassette 15. For this, a reporting chain conveyor 2 is turned on, which feeds one bar 3 with smoked fish to the feed bars of the loading conveyor 1. This ratio of the supply of rods 3 with smoked fish corresponds to the optimal filling of the cells in the accumulation cassette 15 and at the same time the remainder of the fish carcasses supplied by the reporting conveyor 2 will be minimal. The trimmed fish whistlers q of the reporting conveyor 2 fall on the elastic belt of the conveyor 5 between the leads 6. The speeds of the conveyor belt 5 and the leads 6 attached to the chain 7 are synchronized so that there is no relative movement of the fish carcasses on the belt, since such movement gives rise to friction between the fish and the conveyor belt, which can damage the skin of the fish. Upon further transportation of the carcass, the fish arrive at the platforms 8, which form the continuation of the elastic belt of the conveyor 5. Movement of fish ducks through platforms 8 takes place due to pushing of fish by leads 6 along the surface of platforms 8 until the haul reaches the vertical station 8, which forms the slit, into which it falls through with its further pushing by the leads 6. The fish, having fallen into the slit, continues their further way under the action of the forces of its own weight between the barriers 18 and at the end of the fall falls onto the leaf spring 16. Under the The action of the mass of fish thrusters on the plate spring 16 closes the contacts 17 and a current flows into the coil of the solenoid 12, while the core 14 rises up along with the rod 11, which turns the curvature 10 fixed on the axis 9 with the platform 8, and the latter closes the space above the accumulator cell cartridge 15. When triggered solenoid 12, fixed on pin 11 pin 30, closes the contacts a and a. The following fish dropping into the free cell of the accumulator cassette 15 causes the solenoid 12 of this cell to operate, and contacts, for example, g and g, etc., are closed. When all the solenoids 12 are operated, then fish thrusters will be placed in all of their cells in the accumulation cassette 15 and, accordingly, contacts a, b, c, d ... n) will be connected to contacts a, b, c in 30 using the contact bars 30. .. and the switch 28 will turn on the electromagnetic clutch 26, the latter will work and connect the cams 20 through two pairs of gears (bevel) 25 and 27. When the cams turn, the storage cassette 15 will gradually lower and, when it takes a horizontal position, the contacts 29 are open and de-energized electromagnetic clutch 23, due to then the feed conveyor 1, dokladochny conveyor 2 and the chain 7 are shutdown. At this time, the pushers 19 {FIG. 1, the dotted line) the whistlers will be overloaded into the shaper of the laying machine. As soon as the carcasses are released, the accumulator cassette 15 and the pushers 19 return to their original position, the spring plates 16 rise, the contacts 17 open, the solenoids 12 are de-energized and the cores 14 under the action of the total mass of the cores 14 with the rods 11, the curvatures 10, the contact strips 30 and The pads 8 are empty, the pads 8 will take their original vertical positions. Kinematically, at this time, the accumulation cassette 15 will once again occupy an inclined position and the contacts 29 will close, thus activating the electromagnetic clutch 23, which will result in the movement of the loading conveyor 1 and the circuit 7, which will resume the supply of drains for filling the accumulation cassette. Then the cycles will be repeated. The number of chucks provided by the conveyor belt 2 from one rod 3 will be greater than is required to fill empty cells in the accumulation cassette 15 in two cycles. In order to dump excess carcasses from the conveyor 5, a reset device is provided in the device. The proposed device for loading smoked fish into a stacking machine eliminates the work of stackers in laying fish ducts in the cells of a fish-laying machine, increases the production of rfocTb by eliminating stops in the cans to report fish to banks, improve product quality due to the lack of hands touching fish ducts during laying in the cells of the conveyor cassettes, thereby significantly reducing the bacterial contamination of products. The use of the proposed device in a single laying machine according to h A smoked carcass of fish in cans, which tentatively provides an annual economic effect of 15 thousand rubles.
