Description

The invention relates to packaging equipment and can be used in any branch of the national economy.

The purpose of the invention is to reduce the dustiness of the environment.

The vertical arrangement of the rigid chambers and the provision of them with a flexible chamber isolates the unstitched zone from the environment.

FIG. Figure 1 shows schematically a device for unpacking bags, bulk cells with bulk material, a general view; in fig. 2 - the same, top view; in fig. 3 - loading chamber, general view in axonometry; FIG. 4 - the same, with the bag feeder raised to the middle; in fig. 5 - the same, with the bag feeder in the extreme upper position; in fig. 6 - screw conveyor, general view; in fig. 7 - the same, top view; in fig. 8 is a section A-A in FIG. 7

Dispenser. packages of bulk materials with a bulk material contains a cutting mechanism consisting of a screw conveyor 1, a lifting platform 2 with a drive 3, a loading chamber 4, a separator 5, a device for withdrawing bulk material and a mechkotary including cheek 6, a small chip 7 for resetting the bag and a node 8 air cleaning device.

The loading chamber consists of a movable rigid chamber 9 and a fixed rigid chamber 10 located under it, interconnected by a flexible chamber 11. In this case, the rigid cameras 9 and 10 have a rectangular parallelepiped shape in cross section.

The rigid chamber 9 is bounded on three sides by walls, two of which have grooves 12, the height of which allows the drive mechanism 3 to move inside the rigid chamber 9 to half of it.

Tight chamber 10 is bounded by walls on four sides. The cross-sectional dimensions of the chamber 10 are larger than the cross-sectional dimensions of the rigid chamber 9.

The bending chamber 11 is made in the form of a regular truncated quadrangular pyramid bounded on all four sides, the dimensions of the lower and upper parts of which coincide with the dimensions of the cross-section of rigid chambers 9 and 10.

At the junction of rigid 9 and flexible 11 chambers, there is a frame 13, the internal dimensions of which are smaller than the edges of the lifting platform 2, but larger than the dimensions of the grooves 14. On the surface of the frame there is a flexible bezel 15, the internal dimensions of which are smaller than the dimensions of the edges of the grooves 4.

In the upper part of the rigid chamber 10 there is a screw conveyor 1, the screws 16 of which are self-cleaning and are kinematically connected in pairs by a chain 17.

In this case, each pair relative to the other has opposite winding and rotation.

Knives 19 are located on feathers 18 18 of the screws with a certain pitch for contacting through the grooves 20 located at the same pitch on the shaft 21 of the adjacent screw. At one screw, the shaft 21 of the other is constantly touched, adjacent to the shneek of the pair. Between the two pairs there is a gap that does not allow the knives and feathers of adjacent screws of different pairs to touch each other.

On each groove 14 there are grooves 22 located at the same pitch as the knives 19 on the respective feathers x 18 of the screws 16.

A device for unpacking bags of bulk material works as follows.

Platform lift 2 lowered. At the same time, the rigid chamber 9 is open only on one side. With the help of a loader, the bag is introduced into the rigid chamber 9 and installed on platform 2. Then the drive 3 is turned on and the platform 2 together with the bag starts to rise. At the same time, the rigid chamber 9 remains stationary, since the drive mechanism 3 moves inside the grooves 12. Next, the edges of the grooves 14 pass through the frame 13, bend the edges of the flexible lining 15 and, together with the package, are completely inside the flexible 11 and rigid 10 chambers. At the same time, the lining on all four sides without a gap covers the contour of the grooves 14. At the moment of contact of the drive mechanism 3 with the transverse edge of the grooves 12 and the edges of the platform 2 with the frame 13, the internal volume of the loading chamber is completely isolated from the external environment, i.e. Full sealing of the loading chamber occurs. At this time, together with platform 2, the mobile rigid chamber 9 starts moving upwards. Then the bag comes in contact with (the legs 16 of the screw conveyor 1, since the height H of the bag is less than the height of the rigid chamber 9.

When the bag comes in contact with the screws 16, the bag is simultaneously disbanded and the bulk materials are emptied out of the bags as the knives 19 cut the bags and the screws 16 of the screw conveyor 1 begin to transport and discard the mixture consisting of pieces of broom and bulk material into the separator 5. Under the influence rotating blades 23, the bulk material is sifted through the sieve 24 and removed from the device by the screw 6. The pieces of the mesh are further cleaned from the bulk product by blades 25 and dumped into the shaft 7, from where they lead with the apparatus. The air cleaning unit 8 prevents dust formation.

The shaft 21 of the screws 16 is continuously cleaned from the wrapping pieces of paper.

bags, since the feather of one auger 16 constantly touches the shaft 21 of another, near each other, of the auger of this pair. In this case, the knives pass through the nazi 20, thereby not preventing the self-cleaning of the screws 16.

When the platform 2 with the rigid chamber 9 begins to move together, the lower part of the flexible chamber 11 bends inward and also begins to move upwards. At the same time, the lifting platform 2 gradually, the movable rigid chamber 9 and the flexible movable chamber 11 begin to move inside the rigid chamber 10.

In the upper extreme position, the flexible chamber 11 is completely reversed and the lower part rises above the upper part to the height of the flexible chamber 11. At the same time, the grooves 14 occupy the extreme upper position, the knives 19 pass through the grooves 22, thereby preventing the feathers 18 m screws 16 from being removed from the surface of the grooves 14 of the form
