Description

The invention relates to equipment for the mechanization of loading and unloading operations in warehouses, elevators, and can be used for unpacking bags with grain, sugar, seeds, flour, cement, etc. The invention provides for unpacking bags, shaking them and placing them on a cart.

Devices for unloading bags with bulk materials are known, comprising a conveyor with grippers fixed at intervals, knives for cutting bags, a bag shaking unit, a hopper for bulk material. However, these devices are complex in design and unreliable in operation.

The prototype of the proposed device is a device containing a conveyor with rotary grippers fixed at a certain interval, the upper and lower guides, the last of which is made with notches to ensure

shake empty bags, and bulk material hopper.

The aim of the invention is the creation of a simple in design and reliable in operation of the device, ensuring the unloading of bags, shaking them and laying on the cart.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view; in fig. 3 - an exciting mechanism.

The device for unpacking the bags contains a conveyor 1, on the tape of which, at certain intervals, clamps 2 are installed, consisting of hooks 3 mounted on a rotary axis 4 placed in a cylindrical tube 5, having transverse slots 6 for hooks. At both ends of the axis are sliders 7 and spring 8, connected at one end with the axis, and the other with a pipe. The tubes are rigidly connected to the plates 9, with which the gripping mechanism is attached to the tape. The device is also equipped with a lock.

with about

bags 10, consisting of spring-loaded plates 11 of a certain configuration, placed on a vertical axis 12 on both sides of the conveyor, and guides 13 located on both sides of the conveyor, and in the lower part, the guides are zigzag-shaped. A pallet 14 and a hopper 15 for bulk material are installed under the conveyor.

The device works as follows.

The pre-embroidered bag 16 lays down (or comes from the conveyor) onto the conveyor belt 1 of the device and moves to the latch of the bags 10, where it stops, aligns and slides along the moving belt until the grip 2, which pushes the bag, opens the latch, and, together with the bag, moves to the guides 13. The slides 7, touching the guides, rotate the spring-loaded axis 4, the hooks 3 enter the bottom of the bag and together move to the conveyor drum, where the bag is turned upside down, the contents are emptied and held Seizure bag passes to zone shaking. When the sliders 7 pass through the zigzag guides 13, the bag is repeatedly shaken, released from the remnants of the contents into the tray 14, and then the sliders slide off the sliders, the hook axis 4 returns to its original position, the bag drops from the hooks and falls onto the cart 17:

Claims (3)

Claim 1. Device for unloading bags with bulk material, comprising a conveyor for moving bags with pivot hooks fixed at a certain interval, upper and lower guides, the last of which is made with notches, to provide shaking of empty bags and bunker for bulk material characterized in that, in order to increase reliability of operation, the grippers consist of hooks mounted on a rotary axis placed in a cylindrical tube having transverse slots for hooks , wherein the axes are spring-loaded with respect to the pipe and have slides at the ends for interacting with the guides. 2. The device according to claim 1, characterized in that above the conveyor is placed a clamp of the position of the bags, consisting of two spring-loaded plates fixed at one end on the vertical axis on both sides of the conveyor. 3. Device pop, 1, characterized in that a tray is installed under the conveyor to collect the residual contents of the bags when they are shaken. ft ABOUT cvi ve II II II AI & "S it oi Јr Yu
