The guide sleeve 32 is fixed on the plate 26 by means of an L-shaped shaft 34, one end of which is freely mounted by means of the sleeve 35 on the plate 26, and the other 36 is mounted on the sleeve 36 and an annular groove d is made, which includes a screw 37 screwed into the sleeve 36, the guide bushing 32 is fastened to the sleeve 37. The gate gripper body 6 moves in the groove of the plate 5 and the plate 38 is not fixed on it, carrying a wall 39 in which axis 40 is installed. On axis 40 it is installed at one end of a ha 41 ( lever), the other end of which is pivotally connected with one and all the other rod (arm). On base 1, a sleeve 45 is fastened with the help of a cap 44 bracket, in which a rack 47 is spring-loaded with a spring 46 and a shaft 48 is mounted with splines 49, the spline sleeve 50 is moved, driven by an electromagnet 51 through a hinge on two bases spring-loaded lever 52 A gear 54 is mounted on shaft 48 and engages gear rack 47 and splined hub 50. T ha 43 is spring-loaded to bracket 44 by spring 55 and secured with a free end on shaft 48. On base 1 it is hinged the arm 56, pivotally connected to the rack 47. Sheets 57 are loaded onto a carriage 58 consisting of two plates, each of which has spring-loaded stops 59 and cutting torches 60, shafts 61, bearing down arms 62, and two shoulders levers 63, interacting with tools 64. The device works as follows. Rotate the screw 19 to adjust the device to ensure the separation of the sheets 57 with a certain thickness. In this case, the front walls of the cassettes remain at the same level. With the separation of two sheets 57 from the feet lying on the plate 12 of one of the cassettes and on the slats 30 of the other cassette, the screw-19 on the rack 8 is rotated in the direction shown by the arrow (figure 1). In this case, the bracket 20 moves downward along the guide columns 23 and at the same time lowers the sleeve 32 with the cassette towards the carriage 58 of the sleeve 10 along the guide column 9 with plates 11 and 12. When the bracket 20 moves down the rack 22, it interacts with the gear wheel mi 15 and 18, turns them. Gears 15 and 18, interact with the racks 14 and 17, respectively, move them up. The toothed rail 14 moves the plates 11 and 12 upward to a predetermined distance, and the toothed rail 17 also to the specified distance moves the plate 5 along the guide columns upwards. Together with the plate 5, it moves upward and the lower gripping member 6. As the carriage 58 moves, it starts to enter the gap between the strips 30 and the plate 12 and acts on the end of the two shoulders lever 56, which rotates and moves down the gear rack 47 in the sleeve 45, squeezing the spring 46 The toothed rack 47 rotates the gear 54 together with the shaft 48. The shaft 48, through the rods 43 and 41, moves the gate engaging body 6 along the groove O to the left (FIG. 1). The stops 7 separate the bottom sheets 57 from the foot lying on the plate 12 and move them under the card 58. The separated sheets 57 at the end of the feed stroke act on the sensor 13, which sends a signal to turn on the electromagnet 51. The electromagnet 51 through the double-arm lever 56, overcoming the force of the spring 53, moves the slotted sleeve 50 along the shaft 48, the sleeve leaves the engagement with the gear 54, which begins to rotate freely on the shaft 48 and the gate grip body 6 stops moving to the left. When the carriage 58 leaves the engagement with the two shoulders lever 56 under the action of a spring of 55 tons a hectare 43 rotates together with the shaft 48 and through the pull 41 moves the gate gripper body 6 to the initial position. The toothed rack 47 under the action of the spring 46 moves in the sleeve 45 to its original position. Upon further movement of the carriage 58, the spring-loaded stops 59 separate the lower sheets 57 from the foot lying on the strips 30. As the carriage 58 leaves the loading area, the sheets 57 are pressed against the hollow cutters 60 by the pressing levers 62 and out of the interaction with the sensor 1 3. The sensor 13 sends a signal to turn off the electromagnet 51. The double-arm lever 52 is rotated by the action of the spring 53, moves the splined hub 50 along the shaft 48 and interacts with the gear 54. Then the cycle repeats. The effect of using the device is to improve the service conditions by synchronizing the height adjustment of the slide valve body and the table.
