SU113150A1 - The device for packaging in the boxes of fish and crushed ice - Google Patents

Description

Equipment for packaging fish and crushed ice boxes is known, including a feeding tank for fish, a crusher for crushed ice, a rotary ice dispenser, a weight mechanism for fish and a belt conveyor for moving the boxes.

The proposed device is more advanced than the known devices of the same type and has a higher performance.

The peculiarity of the device is that the weight mechanism for fish is made in the form of two successively working weight bins, over which a sleeve is placed hingedly attached under the feed bin to the fish flow, equipped with an electromagnetic drive, an electrical circuit connected to the contacts located under the weight bins and closed by them when reaching a given weight.

Under the weight bunkers there is a system of unbalanced and pivotally connected levers, having the form of a beveled parallelogram supporting an empty box above the conveyor and lowering it onto the conveyor after being filled with fish.

FIG. 1 shows the described device; figure 2 - its front view; in fig. 3 is a section along AA in FIG. I; in fig. 4 - weight bunker; in fig. 5 - kinematic diagram of the device.

Above the continuous conveyor belt conveyor / there is a feeding bin 2 for fish and a bunker 3 for crushed ice. Under the hopper 2, the transfer sleeve 4 is hinged to prevent the flow of fish into one of the weight hoppers 5 located under it.

 In order to prevent the scattering of fish beyond the bunkers when the sleeves roll over the weight hoppers, the fixed nozzle 6 is placed.

N ° 113150-2. The weight bins are mounted on the weighing device 7, on the lever 8 of which there are two loads, of which one load 9 is stationary. By peremegtseniem but the lever of the second load 10, you can adjust the weight of fish dosed in the crate from 20 to 40 kg.

Each weight bin 5 has an inclined bottom I, but which the fish crawls to a folding wall 12, which is located at an angle of 10 ° to the vertical. The flap wall is locked in the closed position by the locking lever 13.

As the fish enters the weight bin, it is lowered. At that moment, when the weight of the fish arriving in the bunker 5 corresponds to a predetermined value, the contacts 14 located under the bins close, an electrical circuit 15 connected to the electromagnets 16, which throw the sleeve 4 with the fish flow to another weight bin. When the weight bin 5 is subsequently lowered, its locking lever 13 abuts against the stop 17, which opens the locking latch of the locking lever.

Under the influence of the weight of the fish, the folding wall 12 of the bunker moves to a vertical position and the fish is poured out into the box 17a located under the bunker 5, fed by conveyor 1.

To bring the flap wall 12 back to its initial position, a spring 18 is mounted in the hopper, having adjustable tension.

The final closing of the bunker to the latch is made by the lever 19, one end of which is located on the path of movement of the box. Box 17a, with fish moving along the conveyor /, rests against the end of lever 19 and lifts it upwards. The opposite end of the lever closes the folding wall of the 12 bunker.

The empty box is placed on the receiving device of the box holder 20, the corners of which are located on both sides of the conveyor belt. The corners are mounted on a system of unbalanced and pivotally connected levers 21, having the form of a beveled parallelogram. Due to the weight of the long arms of the levers, the corners are raised above the conveyor belt. The weight of this shoulder is adjusted so that the empty crate cannot fall onto the conveyor belt. When the fish enters the box from the weighing bin 5, under the influence of the weight of the box and the fish, the corners of the box are lowered, the box becomes on the conveyor belt, which carries it under the rotor ice pack 22. On the way, the weight bin cleared from the fish is closed.

The rotary ice dozer 22 is located under the receiving bin 3 for crushed ice and is divided by a partition into two halves. The rotor rotates periodically 180 ° from the shaft 23 of the conveyor drive station / through the chain drive 24, the bevel gear 25 and the friction clutch 26.

There are two projections on one of the clutch plates. When one of them rests against the stop on the locking lever 27, the ice-rotor rotor remains stationary. At this time, the clutch slips.

The dosage of ice is by volume. Removable inserts 28 can be placed in both chambers of the rotor to adjust the volume and adjust the dosage of ice from 50 to 100% of the weight of the fish in the drawer.

A hopper 29 for dosed ice is located under the metering device. The bottom of the bunker consists of two halves 30, mounted on the bows. Each half has a counterweight with a load of 31, which supports it in the closed position in the absence of ice.

The bottom of the hopper 29 is opened by the weight of the ice. After the ice has poured out, the counterweights bring the halves of the bunker bottom to the starting position.
