Description

one

The invention relates to equipment for the unloading of bags with various bulk materials and can be used, for example, in the chemical industry for unloading bags of powdered chemicals.

A device for unpacking bags of bulk materials is known, containing its accumulator of accumulated bags, conveyor, needles and devices for opening, shaking and removing them from needles located in its housing.

The purpose of the invention is to completely release the bags from the material and prevent damage to them.

The proposed device is equipped with a mechanism for pushing bags into a working chamber consisting of a lever, a roller bearing, guides and a hydraulic cylinder, while the lever is connected to the hydraulic cylinder and cantilever mounted on a roller support for movement along the guides, and the bag opening device includes a spring-loaded a lever hinged on the inner wall of the body, a spring-loaded plate hinged to the lever, and a disk knife with a drive. The device for removing the bags from the needles should be made in the form of longitudinal grooves formed along the length of the guides for the passage of the needles.

FIG. 1 shows the described device, top view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. 2; in fig. 4 shows a section along BB in FIG. 2; in fig. 5 is a section along G ‑ Y in FIG. four; in fig. 6 is a section along d-d in FIG. one; in fig. 7 is a section along E-E in FIG. 2; on

FIG. 8 is a section along LF in FIG. 7

The device consists of a body 1 with a loading opening 2 for filled bags and discharge openings 3, 4 for material and for empty bags; disk drive

the knife 5, the conveyor 6, the accumulator 7 filled bags, the accumulator 8 empty bags, the mandrel 9 connected to the knives 5 and the sleeve 10 with the possibility of axial movement in it and with the bearing support on

axis 11; drive 12, transmitting the rotation of the knife 5 through a pair of cylindrical gears 13 and the front key 14; wall 15, pivotally mounted on the lever 16, spring-loaded springs 17 and 18 and pivotally

mounted on housing 1 and on the plug 19, fitted with two fingers 20 with rollers, the entrance is into the grooves of the axis I; a rack 21, a movable removable stop 22 mounted on a carriage 23 moving along box guides 24 and 25 by means of a winch 26, the drum 27 of which is mounted on the support of the guides and provided with an actuator 28, and the cable 29 passes through the internal cavities of the guides and closes through the two deflecting units 30 and the tensioning unit 31 mounted on the second support post of the guides; a cantilever 32 provided with a roller bearing 33 moving along the guides 34 by means of a pneumatic cylinder 35; spring wall 36 interacting with limit switches; a pivot flap 37 holding the bag from tilting before the loading opening 2; the drive 38 of the winch drum of the conveyor 6, the cross member 39, the strip 40, the pneumatic cylinder 41 mounted to oscillate around the axis 42 between two rubber shock-absorbing tiles 43 and connected to the rod 44 and the needles 45, while the fifth 46 is rigidly connected with the needles 45; vibrator 47; fencing 48 needles 45; an apron 49, guides 50, pneumatic chambers 51, a pneumatic cylinder 52 for pressing in empty spacers attached to the stem of the cross 53 and a pipe 54 for suctioning air.

The device works as follows.

The bags are stacked on the rack 21 and the stop 22 moves up to the stop of the first mechelka in the spring-loaded wall 36. Then the device for pushing the memesh with its cantilever 32 feeds it into the loading opening 2, while the bag takes the position indicated in FIG. 7, and the wall 15, shifting to the left, through the lever 16 will expose the knife 5 in the middle of the height I am a mechelka.

After that, the pneumatic cylinder 41 punctures the needles onto the needles 45, and the conveyor carriage 6, moving along the housing 1, pulls the bag through the knife 5, which rips the bottom of the bag.

Moving further along the guides, the carriage of the conveyor 6 stops along the axis of the vibrator 47, where the remaining material is wrung out of the bag into the discharge opening 3, and in the rightmost position (see Fig. 1) of the needle 45, exit from the housing 1, emptying the bag into the accumulator 8, after which the carriage of the conveyor 6 returns to its original position and pushes the next bag onto the needles 45.

The pneumatic cylinder 52 with the help of the crosspiece 53 seals the empty small cells in the accumulator 8, which is periodically replaced. At the same time, when the stop 22 moves (see Fig. 3), a new batch of bags is installed on the rack 21, and after pushing the last bag from the first batch into the loading opening of the body, the stop 22 is removed from the carriage 23, which returns to its original position (leftmost, see Fig. 3), and a stop 22 is placed on it, which begins to deliver a new batch of bags to the loading opening of the body.

The operation of the device is controlled through limit switches.
