SU480610A1 - Overhead conveyor for transporting animal carcasses - Google Patents

Description

The invention relates to devices for transporting animal carcasses in the process of their slaughter processing and can be used in mills for mechanizing the transport of animal carcasses in all parts of their slaughter processing.

Suspended conveyors for transporting animal carcasses are known, containing brackets, guides attached to them for trolleys with animal carcasses suspended from them, located between the beam guides, drive chain with vertical pusher fingers for TpOileas and an additional mechanism for supplying paired trolls to the beam. scales, set in motion with a speed exceeding it, value the speed with vertical pushing fingers, and equipped with horizontal stops.

However, on these conveyors, the pairing of two half-carcasses of the same carcass when feeding them to the beam of the balance is done manually.

For the automatic picking of two half carcasses of one ink when feeding them to the beam of the weights in the proposed conveyor, an additional mechanism for supplying paired trolleys is made in the form of a rod fixed on the stem of the power cylinder, controlled by spool valves. In addition, the spool valves of a power cylinder can be kinematically connected with a contact device made in the form of a Maltese cross installed on the track, interacting with trolls.

FIG. 1 depicts the described conveyor, general view; in fig. 2 - spool valve control system.

The overhead conveyor includes brackets, guides 2 and 3 attached thereto for trolls 4 with animal carcasses suspended thereto, located between the beam guides 5 weights, the driving chain 6

with vertical pushing fingers 7 for trolleys and an additional feeder for snagged trolleys to the beam of the balance, consisting of a pneumatic cylinder 8 with a piston 9, a rod 10, a rod 11 with horizontal stops 12-14, rollers 15 mixing along the guides 16, a Maltese cross 17 with solenoid 18, rod 19 with pivotally connected with it by the levers of 20 spool valves 21, pipeline 22 n limit switch 23.

The conveyor works as follows. Animal carcasses are suspended from trolls 4, which, when the chain 6 is moving, engage with a vertical pushing finger 7 and move along guide 2 of the conveyor.

To the weighing site (after cutting the carcass into two symmetrical halves), the first vertical pushing finger moves only one half-carcass, and the subsequent fingers move two half-carcasses from different carcasses.

The pushing finger 7 of the trolls, carrying the first half, is fed by the horizontal stop 12, hinged on the rod 11, reciprocating at a speed exceeding the speed of the zepra with the vertical pushing fingers.

At the same time, the trolls turn the Maltese cross 17 by 45 °. The next pushing finger feeds the trolls, carrying the second half-drag, behind the horizontal stop 12 and when the Maltese cross rotates by 45 °, the solenoid 18 turns on, which sets the rod 19 and the joint levers of 20 spool valves 21. Through pipe 22 into the pneumatic cylinder 8, air is supplied with a pressure of 2-2.5 atm and piston 9 through rod 10 is moved by a rod 11 with a horizontal stop 12, thereby supplying the troll carrying the second Half carcass, to the trolley carrying the first carcass, and their joint movement to the beam 5 weights.

With the next stroke of the rod, the horizontal stops 14, 13 and 12 remove the first pair of half-holes from the beam (after lifting), the second pair is placed on the scales, and the third pair is completed in front of the beam. Thus, the process occurs continuously in the presence of trolls on each finger of the conveyor.

To feed the last half carcass pair to the beam at the end of the shift, as well as when the conveyor is not fully loaded, the pushing mechanism is equipped with a limit switch

23, which closes the circuit of the solenoid when passing the plate with the pushing finger of the conveyor in case this finger does not push the trolls with a half-emitting light. At the same time, by the stroke of the rod, the last two coupled half-carts are placed on the beam of the balance.

From the end switch, the rod can be set in motion only once before the next turn of the Maltese cross by a trolley carrying a half carcass.
