Description

1

The invention relates to machines for the mechanization and automation of loading and unloading X works and is intended for the layer-by-layer disassembly of packages of piece goods, such as paper bags.

The purpose of the invention is to improve performance by eliminating congestion on the discharge conveyor.

Fig, 1 - a common device; in fig. 2 - gravity transporting platform with orienting elements.

The device consists of a frame 1 with inclined guides 2 fixedly fixed on it, made with a bend at the level of the upper layer of the package, the angle of which is equal to or greater than the friction angle of the transported material, but does not exceed 45 °. In the guides 2, a lifting and lowering platform 3 is mounted, moving on rollers 4 by means of a chain conveyor 5, which is connected to platform 3. The metal peg-ecladins of the chain conveyor 5 simultaneously serve as an abutment wall b for the front side of the package. The upper edge 7 of the stop wall 6 of the chain conveyor is inclined to a horizontal surface, the height of which is equal to the thickness of the bag.

On the frame 1 from the anti-propelling side of the guides 2, in the zone of the upper edge 7 of the stop wall 6, an inclined gravitational-transporting platform 8 is mounted with an inclination angle equal to or greater than the friction angle of the material being transported. For the individual separation of the layer of the package into separate bags, the separation platform is provided with orienting elements 9, made in the form of conical segments, installed flat in such a way that their vertices are facing the abutment wall 6, and the semi-bases to the discharge conveyor 10. The orienting elements 9 are divided by gravity -transport area into several equal parts, and in the lower part the width of the passage between the orienting elements 9 is equal to the width of the bag, and the height of the segments is equal to the thickness of the bag.

The discharge conveyor 10 is installed along the bottom edge of the gravity transporting platform ;.

For better orientation and reversal of the bags that are lowered across the outfeed conveyor, the tank wall 11 of the discharge conveyor 10 is pushed halfway from the belt edge.

The device works as follows.

A bag of bags laid, for example, with an electric forklift on a pallet platform, is installed on a lifting and lowering platform 3. The drive of the chain conveyor 5 and the drive of the discharge conveyor 10 are activated. Lift up

guide 2, platform 3 tilts. The bags of the upper layer of the package, the protrusion above the inclined upper edge 7 of the supporting wall 6, slide down onto the gravity transporting platform 8. At the same time

First, the bags located in the lower part of the slope fall, then as the platform 3 rises, the bags located in the upper suit of the slope fall.

The bags, moving along the gravitational-transporting platform 8, slide along the lateral surface of the orienting elements 9, they are spread out in different directions and individually lowered onto the discharge conveyor 10, the belt of which moves at a speed 3-5 times higher than the speed of movement of the bag along the gravity transporting platform 8. Such a ratio of speeds allows the piece to pick up the bags

high-speed lateral conveyor 10 and at the same time orient them along the axis of the latter. When the lowered bag is turned across the outlet conveyor 10, the first half of the bag, abutting against the side wall 11, is located on a fixed horizontal platform, while the second half of the bag, moving together with the tape of the outlet conveyor 10, unfolds the bag along the latter, thus avoiding way congestion and blockages bags. Similarly, the subsequent layers of the package are disbanded with uniform movement of the platform 3 along the inclined section of the guides 2.

After the last layer of bags has come off, the upper roller 4 of the pad 3 rests on a limit switch (not shown) and the platform lowers. When installing the platform 3 to its original position is triggered

a limit switch (not shown) and stops the motor of the conveyor 5 and the discharge conveyor 10. The empty pallet is manually removed.
