Abstract

The invention relates to a device for gripping filled bags and can be used during loading and unloading operations. The aim of the invention is to simplify the design and reduce the metal consumption. A device for gripping the filled bags 1 comprises a housing with two parallel plates in which grooves are made, a pair of clamping rollers — movable 7 and fixed 8, direction and dampers. On the movable roller, the retainer 12 and the additional roller I are rotatably mounted around the latter. The movable roller is installed in the slots of the plates with the possibility of mixing and spring-loaded. The neck of the filled bag 1 is bent through the movable clamping roller 7 and is pulled over the additional roller 11, turning the lock 12 at a certain angle. When the device is lifted by the weight of bag 1, the movable roller 7 presses against roller 8 and captures bag 1. When bag 1 is installed on the supporting surface, the clamp 12 will again take up a vertical position, resting on roller 8, and with subsequent lifting of the device, the neck will release . 4 il. € (L

The invention relates to lifting devices used in loading and unloading operations.

The aim of the invention is to simplify the design and reduce the metal consumption.

FIG. 1 shows a device for capturing filled bags, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 - position of the filled MeuJKa before capture; in fig. 4 — bag in trapped condition.

The device for gripping the filled discs 1 includes a housing 2 with two parallel-arranged plates 3 and 4, in which grooves 5 and 6 are made, a pair of clamping rollers — movable 7 and fixed 8, guides 9, shock absorbers 10, an additional roller 11 placed between the clamping 7 and 8, and the latch 12 with the handle 13, and the additional roller 11 and the latch 12 is fixed on the axis

at the same time, they will be in a compressed state until plate 1 is placed on the supporting surface.

When installing the meter 1 on the supporting surface, its weight on the roller 7 stops and under the action of the shock absorbers 10 the roller 7 moves along the grooves 5 and 6 to the upper extreme position, and the latch 12 takes up the initial vertical position, preventing the roller 7 from moving downwards. When the device is lifted again by the yoke 14, the neck of the bag 1 is freed from being gripped.

Thus, the use of a device for gripping the filled meshes allows to simplify the design and reduce the metal consumption, since the mesh and the clamping of the neck are made by clamping rollers under the weight of the latter, and when the weight of the load is removed, the mesh spacer is released from the roller - 20 kami, which are returned to the original convolution around the axis of the latter, and the movable roller 7 can move along the slots 5 and 6 of the plates 3 and 4 and is spring loaded.

The device works as follows.

The neck of the filled mech room 1 is bent through the movable clamping roller 7 and is pulled over the additional roller 11, turning the retainer 12 at a certain angle, which in the initial vertical position abuts the axis of the fixed roller 8. When the device is lifted, the yoke 14 together with the bag 1 roller 7 It begins to descend along the grooves 5 and 6 under the action of the weight of the mecchal 1 and, approaching the roller 8, at the same time turns the additional roller 11 at an increasing angle. The movable roller 7 is pressed against the fixed roller 8 with a force equal to the weight of loaded bag 1. Dampers 10
