Description

The block of bandages in wrapping paper is mounted on frame 18 (see Fig. 4), having main rollers 19 and 20 and spring-loaded pressing rollers 21 and 22. E cassette 16 has grooves for entry into them of plugs 23 (see Fig. 2 ). Gears 24, rail 25, lever system 26, and cam 27 mounted on camshaft 2 are provided for rolling the pins 23 into the swinging motion. On the spring-loaded clamp 10, a hinged door 28 is mounted to prevent wrapping paper from breaking when pins 23 are raised. Frame 1 is equipped with crimping pads 29, 30 for securing the gluing of the sides of the block and conveyor 31 (see Fig. 1). The conveyor 31 has two W, EKI - 32 and 33, rigidly interconnected, a chain 34 (see Fig. 3), a leading sprocket 35 and a slave 36. On a cecium 34, plates 37 are fixed with a certain pitch, on which they are alternately mounted on The front pins 38 and rear 39 pins. One end of pins 38 and 39, protruding above the bandage transfer plane, is designed to form with the side cheeks 32, 33 cells that serve to put the bandages into the block. At the second ends of the plugs 38, 39, the rollers 40, 41 are rotatably supported, interacting with horsemen 42-47 fixed on the cheeks 32, 33 and giving the position 38, 39 to the pin 38, 39. For tensioning, an eccentric 48 located on the cheek 33 is provided. On the plates 37, the cams 49 are fixed with axial adjustment, giving a command to stop the conveyor 31. The mechanism 15 of synchronous movement of the cassette 16 and the pusher 14 (see Fig. 2) installed in the frame 1, it has chains 50 and 51. On the chain 50, a cracker 52 mounted in the slot of the frame 17 is displaceably mounted relative to the latter, and on the chain 51 is a cracker 53 mounted in the slot of the frame 54 with the possibility of movement relative to it. For the opposite movement of chains 50 and 51, a pair of teeth 55, 56 is installed inside the bed. A bed raiser 57 (see Fig. 5) is mounted on the bed 1, made in the form of a rotary lever with protrusions and located above the transnorter 31. The ram wire is driven in a swinging pull 58 connected to the cam shaft 2 through a lever system. A folding stop 59 (see Fig. 7) is also mounted on the frame 1, on which adjustable stops 60, 61 are fixed. To fix the two positions of the folding stop 59 when it is rotated around the axis 62, a spring 63 serves. On the frame 54, a bracket 64 is attached, which interacts with an emphasis 59, and an emphasis 65 interacting with a plate 66 fixed on frame 17. A stop 67 is mounted on frame 18 (see Fig. 6) with an adjustable screw 68 interacting with plate 69 fixed on cracker 53. Frame 18 is moved by rollers 19 and 20 (see Fig. 4) but the rails 70 and 71, mounted on the frame 1. Device works as follows. Bandages wrapped in plastic wrap (or unpacked) are manually stacked between pins 38 and 39, forming a 6X5 block of 30 bandages. The distance between the pins 38 and 39 is larger than the actual block size, as a result of which the installation of the bandages is accelerated and facilitated. By pressing the "Start" button, the conveyor 31 is set in motion, and the blocks of bandages located between the pins 38 and 39 are moved one step. The bandage unit, located at the position in front of the cassette 16, enters it, while at the moment of entry, the pin 38 into the cassette 16, the roller 40, meeting the copier 42, turns the pin 38, which goes out of the zone of the cassette 16. With the pin 39, the block of bandages is inserted into the cassette 16 and the block is compressed to a certain size. As the chain 34 of the conveyor 31 rotates, the next bumper 38, meeting on the path of the copier 43 and 44, becomes in the approximate position and, falling into the horizontal copier 46, occupies the vertical position in which it moves. The pin 39, meeting on the side of the two-sided copier 45, is also oriented and, falling into the horizontal copier 47, also occupies the vertical position in which it moves. Nris stopping the chain 34 of the conveyor 31 worker dials the next block of bandages. When the bandage unit is inserted into the cassette 16, a command is given and the packaging part of the machine is turned on, a rammer 57 is triggered, and the bandage unit is compressed to the inner size of the cassette 16. At the same time, mechanism 3 feeds the paper for wrapping bandages, the necessary quantities of which cut off mechanism 4. applies glue to paper. At a certain moment during these operations, the pusher 14 of the nodes by the action of the frame 17 and the chain 50 moves forward, seizes the block of bandages located in the rear part of the cartridge 16, and moves it inside the latter. While moving the inta block inside the cassette 16, the cassette does not move, due to the occurrence of the tray force between it and the bandage unit and because of that the bracket 64 abuts against the abutment 59, and which the spring 63 acts. When the end of the bandage unit reaches the end of the cassette, the plate 66, mounted on the cracker 2, it encounters the stop 65 and, gripping the cassette 16, moves it forward. In this, under the action of the spring 63, the stop 59 leans back in the second position. The cassette 16, moving forward with the block of bandages, stretches the cut and prepared paper for the wrapper along the way, seizes it and, with the paper, enters the shaping area where the side embedment is applied.

longitudinal sides of the block. When the termination is completed, the pusher 14 and the cassette 16 stop as the cracker 52 enters the vertical section by moving it to the chain 50. The frame 17 remains in place, the cracker 52, moving together with the chain 50, goes down and the plate 66 leaves the stop zone 65.

Under the action of the cam 27, the lever system 26 and the slats 25, the gear 24 rotates and the pins 23 rotate, which go under the paper and lift it together with the spring-loaded door 28, preventing, and thereby transferring the glue from the paper to the cassette 16, when the latter is returned to the original position. A rusk 53, moving along the chain 51 in the direction opposite to the displacement of the chain 50, exits the forward straight section and moves the frame 54 backwards. The plate 69, attached to the cracker 53, encountering the screw 68 of the stop 67 along the way, moves the cartridge 16 back to its original position, in which it is held by the stop 59 and the spring 63.

When the cassette 16 is moved backward, the pusher 14 and the bandage assembly remain stationary in the wrapping paper area. Rusk 52, the exit from the zop of the vertical section of the chain 50, returns the pusher 14 to its original position.

The pins 23 are returned to their original position from the action of the cam 27, the lever system 26, the slats 25 and the gears 24. From the camshaft 2, the side, top and bottom edges of the wrapping paper are alternately folded through the corresponding lever systems 11-13. Block

packed, and mechanisms 11-13 return to their original position. In so doing, mechanism 12 returns to its initial position before the next block enters this position. Pressing the Start Machine Cycle button is repeated.

The main components of the proposed device (cassette, pressure mechanism, conveyor) were tested in operation and gave positive results.

The invention will make it possible to create flow-line mechanized production lines for dressing means.
