Description

1 The invention relates to packaging and packing equipment and can be used in any branch of the national economy. A device for unpacking bags with detachable material is known, comprising a platform bag feeding mechanism, a loading chamber with a cutting tool for cutting bags, and a separator l. I A device for unpacking bags made of bags with a conductive material is known, which contains a bag feeder with a lifting platform, a loading chamber equipped with a screw conveyor with cutting tools for cutting bags, and a separator (2j) However, a known device has limited technological capabilities. since it does not provide for the unpacking of bags from bags which are fastened together. The purpose of the invention is to expand the technological capabilities by allowing the bags to be unpacked from The goal is achieved by the fact that in the device for unpacking bags of bulk materials containing a bag feeding mechanism with a lifting platform, a loading chamber equipped with a screw conveyor with a cutting tool for cutting bags, and a separator, the bag feeding mechanism is placed in the loading chamber under the screw conveyor, made in the form of a series of parallel screws, and the screw conveyor troughs are made on the surface of the lifting platform, with at least three side walls one of which separates it from the sepa. The sleeves are flexible shutters that are installed with the possibility of joint movement with a lifting platform. In addition, flexible curtains are made in the form of tensioned on rollers tape, the ends of which are fastened to each other by means of a cable. Moreover, in the upper part of the loading chamber there is a window with flaps, which in the open position form a feed funnel for single bags. 672 FIG. Figure 1 shows a device for unloading bags from bags of bulk material; a general view; in FIG. 2 - the same, top view} in FIG. 3 is a view A of FIG. 5 (with a loaded lifting platform); in fig. 4 - the same, the platform in the extreme upper position, in FIG. 5 a device for unpacking bags of plastic bags with open doors, general view; in fig. 6 - side walls of the loading chamber, in a perspective view. A device for unpacking bags from bulk bags contains a screw conveyor 1, a lifting platform 2 with a drive 3, a separator 4, a screw 5, a shaft 6 for dumping bag pieces and an air cleaning unit 7 in the device. The edges of the screw conveyor screws 1 are sharpened to cut bags, and the screws are parallel to each other. Flexible curtains 8 forming the walls of the loading chamber 9 are fastened to the edges of the lifting platform. The curtains are made in the form of a tape, the ends of which are fastened to each other by means of a cable 10. The belt is tensioned on the rollers 11. In the upper part of the loading chamber there is a window with flaps 12, forming in the open position the hopper for single bags. Gutters screw conveyors are made on the upper surface of the lifting platform. The separator 4 consists of a fixed two-section sieve 13, a shaft 14 on which the blades 15 and 16 are fixed. A device for unpacking bags of bags with bulk material works as follows. The flaps 12 are in the closed position and the lifting platform is lowered. In this case, the loading chamber is hermetically closed on three sides by shutters 8. With the help of a loader, the bag is introduced into the load chamber and installed on platform 2. Then drive 3 is turned on and platform 2 together with the bag is lifted. In this case, the rollers 11 are scrolled, and the curtains constantly keep the loading chamber in a sealed state at the moment the bag comes in contact with the screws of the conveyors 1, the bag is simultaneously deformed and the bulk materials from the bags are emptied, as the sharpened edges of the screws of the conveyors 1 cut the bags and screw conveyors 1 the mixture consisting of pieces of the bag and bulk material is transported and dumped into the separator 4. Under the action of the rotating blades 15, the bulk material is sifted through the sieve 13 and removed from the devices and with the screw 5. The bag pieces are additionally cleaned from the bulk product by the blades 16 and discharged into the shaft 6, from where they are derived from 674 devices. Node 7 air purification prevents dust formation. The execution of the grooves on the surface of the lifting platform allows the height of the bag to be adjusted, while the bulk material is completely generated from the loading chamber. If it is necessary to unload single bags, the platform 2 is left in the upper position, and the chamber is loaded through the hopper formed by the flaps 12. The use of the invention significantly expands the technological capabilities of the device for unpacking bags of interconnected bags.
