Description

 ,

The invention relates to devices for unpacking materials and can be used for unloading predominantly paper bags with bulk materials.

The purpose of the invention is more complete emptying of the bags.

Fig. 1 shows a device for unpacking bulk bags with a general view; Figure 2 iTo, top view; figure 3 - section aa in Fig, 2; figure 4 - section bb in figure 2; figure 5 - the position of the bag at the end of the conveyor.

The device for unloading bags with bulk cargo consists of a chain conveyor encased with a conveyor with branches 2 and 3 diverging in the direction of movement of conveyor 1. Branches 2 and 3 have spikes A for gripping and holding the bag 5.i Between branches 2. And 3 a disk knife 6 is placed, installed so that the top point of the knife forming is above the center of the bag 5. Along the branches 2 and 3, guides 7 and 8 with slits are curved along the counter-helical lines. In the slots of the guides 7 and 8, disks 9 having a wave-like profile are mounted agitated. The angle of inclination of the profile of the guide to the horizontal plane varies uniformly from 0 to angle oi, which is determined from the ratio

where U is the half increment value of the conveyor width; 6 - the length of the bottom wall

in the corner of the bag. At the beginning of the chain conveyor, a spring-loaded roller 10 is installed, ensuring a secure grip of the bag with 5 spikes A. The insertion discs 9 are mounted on the frame 11, while the diameter value ensures that the profile of the disc 9 constantly protrudes over the guides 7 and B.

At the end of the conveyor 1 on the drive shaft mounted ejector 12 dl

Remove empty bags 5 from spikes 4 conveyors I.

A device for unloading bulk bags works as follows.

The bag 5 from the feeding conveyor 13 is fed to the conveyor I. The spring-loaded roller 10, pressing the bag 5 to the branch m 2 and 3 of the conveyor 1, contributes

0 insertion of spikes 4 into the bag 5. During the subsequent transportation, the bag 5 goes to the disk knife 6, which cuts the bag 5. At the same time, the bag 5 finds on the guides 7 and B.

15 The cut-out lower part of the bag 5, which is located between branches 2 and 3, bends under the action of the weight of the load and the emptying of the bag 5 begins. Embed the discs 9 and shake the sections

20 of the bottom wall of the bag 5. The consumption, in the direction of movement of the conveyor 1, of the branch 2 and 3 increases the gap, reducing the portions of the bottom wall that, bending, moving into the upper

25 wall. At the same time, the weight remaining in the folds of the bag 5 is released and poured into the receiving bin 14. As the lower wall sections are diluted, the corners of the bag 5 rise relative to the initial position, which contributes to emptying as the angle of inclination of the bottom wall sections in the area of the bag corners increases. Guides 7 and 8, in shape

from the screw surface, and the shaking disks 9 allow the entire path of the bag 5 to be shaken its bottom wall after being cut. At the end of the conveyor after emptying, the bag 5 is removed by the bodies 12 from the spikes 4 and is taken to a press (not shown).

The use of the proposed device as compared with the device-proto5 type reduces the loss of cargo during unloading of bags with bulk cargo and bags with packed cargo by ensuring more complete emptying of the material from the corners

0 bag, as well as improving the conditions for dumping cargo.
