The bag-forming machine contains a loading conveyor consisting of two conveyors 1 and 2, installed one above the other and having individual drives 3 and 4.

The layer shaper contains a roller conveyor 5, an orienting mechanism 6, mechanisms 7 for turning the bags with a curtain 8, a curtain 9, a mechanism 10 for laying the layer with a folding shutter 11 and a movable roller shutter 12 with a hoisting platform 13 placed under it.

Horizontally movable conveyor 14, receiving roller conveyor 15 and tapping conveyor 16, chain conveyor 17 with lever 18, palletizing shop, the body of which is made with Z-shaped vertical walls, empty pallets lifting mechanism 20 or (fixed elements), lift 21 with grippers 22 and embedded elements, guided, 23, fastened at one end on a lift 21, and at another on a roller table 5, rollers 24 of which are placed above the rails, are made with grooves, installed in the guides of the carriage 25 seconds Rotary in the vertical plane stops 26 and the lifting and lowering traverse -. soy 27 with hinged L on it spring-loaded levers 28, installed with the possibility of interaction with the rotary stops 26 and the limit switch 29, interacting with the spring-loaded plate 30 and with the HbiMH fixed on the rails with the possibility of vertical movement and entering the grooves of the rollers 24 of the roller table using pneumatic cylinders 31 and 32 by the frames 33 and 34, the control of the course of which is carried out with the help of one of the guides interacting with the limit switches 35 and 36, and installed on one of the frames 33. a roller curtain 37 from a pneumatic cylinder 38, the stroke of which is controlled by means of a plate 39 and a limit switch 40. The package contains a mortgage element 41.

The machine works as follows. A stack of empty pallets or mortgage elements 41 is loaded onto the chain conveyor in the store 19 between the Z-shaped walls by means of a loader (Fig. 6). In this case, the Z-shaped vertical walls of the magazine are fixed so that between them a stack of pallets or mortgage elements can be laid, and as the loader moves toward the magazine, it presses the lever 18, which interacts with the limit switch that blocks the conveyor drive.

The conveyor is turned on after the release of the lever ohm. When laying a stack of pallets, the forks of the mechanism 20 for lifting empty pallets are not above the chain conveyor, but rather under the layer of forming the layer. The work cycle is carried out as follows. Pallets for lifting empty pallets or mortgages

elements are pulled out, grab a stack of pallets or mortgage elements 41 and lift it, except for the bottom one. Thereafter, the chain conveyor 17 is turned on and the pallet is fed to the movable conveyor 14. Under the action of the pneumatic cylinder, the conveyor moves and feeds the pallet to the receiving roller 15 and by means of the lifting and lowering platform 13 the layer laying mechanism 10 is fed. After transfer of the pallet to the movable chain conveyor

the conveyor stops and the stack of pallets is lowered onto it and the stack is intercepted, except for the bottom one.

At this time, the bags, the passage between the two conveyors 1 and 2, are shaped and

get on the layer former consisting of a roller table 5, an orienting mechanism 6, a turntable mechanism 7, and a layer laying mechanism 10. Passing over the orienting mechanism 6 bags are stacked in two rows according to a given program, and the third bag passes without transfer to the curtain 8 of the mechanism 7 bag reversal, where it is rotated 90 °. For the first two bags, the income is up to the curtain 9 and wait for the third one, unrolled 90 °

Thus, a layer of three bags is created. Then the shutter 9 is lowered and passes the bags onto the layer laying mechanism 10, onto the roller shutter 12 passes under the shutter 11, deflecting it. By passing r yes under the folding shutter 11 rollers

movable shutter 12 begins to move in the opposite direction and out of the assembled row, stopped by the shutter 11 when it is reversed, and the row of bags is placed on a pallet or another row, and in case of a bottomless assembly directly onto the lifting and lowering platform 13. In the last In this case, the upper row is assembled from two bags, which are turned 90 and the curtain 11 under the action of the pneumatic cylinder occupies the extreme right position. With the packaging scheme with the mortgage element 41, the package forming machine operates in the following manner. The embedment element with the aid of the grippers 22 is removed from the conveyor 14 and passes to its highest position. The carriage 25 is mounted above the inset member lying on the grippers 22. The cross member 27 is lowered under the action of the pneumatic cylinder, the levers 28 are gripping the element, and the roller, resting on the inset element, moves the plate 30 to the limit switch 29, which fixes the element's capture and gives the command to remove element from the grip 22, the element is raised by the return stroke of the pneumatic cylinder. The levers 28 during the return stroke deflect the stops 26 while holding the element. The end of the stroke is controlled by the interaction of the element 41 with the limit switch 42. At this time, the two unfolded bags must lie on the frames 33 and 34, in a high position above the rollers. When forming the third layer, the following occurs. The first bag, reaching the shutter 8, is turned 90 ° by the mechanism 7 of bag reversal and is passed to the shutter 9, where with the aid of the frame 34 under the action of the pneumatic cylinder it rises above the rollers of the roller table by the required amount. The second bag is unfolded, like the previous one by 90 °, arrives at the downy curtain 37, then using the pneumatic cylinder 31 rises on the frame 33 above the rollers by the required amount, and the curtain 37 occupies the upper position controlled by the limit switch 40. After lifting the two bags, the carriage 25 moves and places the Z-shaped element between the raised bags with the entry of the paws of the Z-shaped element under them. Then, the traverse 27 begins to move downwards, while the upper rollers of the levers 23 begin to follow the profile of the folding stops 26, in connection with which the mortgage element 41 is released and it is placed on the rollers of the roller table, while the edge of the element abuts against the bent lever 43 until until the bags are placed on the rollers and bent paws of the insertion element and take up the crosshead 27 of the upper position. After that, a command is given to return the carriage to its original position in order to receive the mortgage element and to further pass the assembled layer for its laying into the bag.
