Description

i1

This invention relates to mechanization for disassembling packages of articles with an inner lip.

The goal of igobregeni is to enhance operational capabilities by providing disassembly of products with an internal protrusion.

On flash 1 shows a package machine, general cd from the side; ka figure 2 - the section in figure 1; on fig.Z - section bb in figure 1; figure 4 - lifting and lowering the table when the contact separators with the protrusion of the product, side view.

Batching machine consists of a frame 1, a lifting and lowering table 2, dividers 3 with levers 4 pivotally mounted on a lifting and lowering table 2, t g 5 with grooves j pivotally connected with levers L, forks 6 with rollers that are placed in the grooves of t g 5, hinged on the frame 1, and the second end through the spring 7 and the stand 8 connected to the centering of the frame 1, the brackets 9 fixed to the side surfaces of the lifting and lowering table 2, the supports 10 with the cams hinged on the inner walls of the frame 1, rack 11, rigidly fixed on frame 1, racks 12 with drives 13, conveyors 14 and 15, springs 16 installed between levers 4 and table 2, return springs 17, racks 18 receiving, spring-loaded tappets 19 with rollers pivotally connected with brackets 9, adjustable stops 20 rotation of the forks 6, the actuator 21, made in the form of a cylinder, on the rod of which is mounted a lifting table 2, adjustable limiters 22 of rotation of the pushers 19.

The product package with the open stand ™ 12 conveyor 14, which is at the top level, is transported to the batching machine and installed on the supports 10. When the working body of the conveyor 14 leaves the loading zone, the drive 13 rotates the stands 12 and the bag is between the stands 11 and 12, are guides.

When the table 2 moves upward with the separators mounted on it, 3 tons of gi 5 also rise, the dividers 3 are in a vertical position, as they are held by the return springs 16. On contact

the rollers of the forks 6 (rollers not shown) with the end of the grooves of the t 5, the levers 4 are turned and the separators 3 connected to them via the axes of the dividers 3, since at this moment the movement of the t g 5 is delayed by the forces of the springs 7 and the dividers 3 along with the table 2 continue to rise. This occurs when the upper parts of the dividers 3 have reached the level located between the protrusions of the lower and the next products. Upon further movement of the table 2 upwards, the dividers 3 enter, into the space between the projections

products. Upon reaching the lower parts of the separators of the stops, their rotation stops (Fig. 4) and when the table 2 moves further, the separation of the foot begins with the formation of a gap

between the lower and upper products (the moment of insertion of dogs of dividers 4 into the space between the protrusions of the products is regulated by the limiters 20 of rotation of the forks 6). When moving the table 2

even higher, the lower product rests on the supporting surface and, lifting together with the table, gradually releases the supports 10, since the pushers 19 with rollers act on their shaped cams. When a certain product lift is achieved, the support cams of the supports 10 exit from under the bottom product and take a vertical position under the action of the pusher 19.

When the table 2 moves down, the rollers of the pusher roll along the linear Φ {sections of the shaped cams of the supports 10, while maintaining the vertical position of the latter. When running rollers with shaped

the cams of the support 10 under the action of the forces of the return springs 17 rotate (this occurs at the moment when the gap formed earlier between the products reaches the zone opposite

the upper parts of the supports 10) and, bypassing the lower product, cut off the rest of the package (the moment of running away of the rollers of the pushers 19 from the shaped cams of the supports 10 is controlled by the limiters 22). The separated product, having passed through the supports 10, is placed on the receiving posts 18, and the table 2 is lowered to its lowest position.

With the same movement of the table 2 down, the legs 5 and the forks 6 also lower. When the plugs 6 touch the stops 20, then the return springs 17 deflect the dividers 3 into a vertical position. Passing past the product racks 18, the separators 3 do not touch it. After table 2 has reached its lowest position, the working body of the conveyor 15, located in

lower level, removes the product from the palletizer.

In the following reciprocating movements of the lifting and lowering table, the package disassembly operations are repeated.
