Description

3. 767

moving the needles over the foot contains a stationary gear 8, around which the shaft 11 is rolled by means of pairs of gears 9 and 10 with housings 12 placed on them, carrying spring-loaded springs 13 with needles 5 moving inside them. Gear 9 of each pair is fixed on the shaft 11, and gear 10 is parasitic. The shafts 11 and the axis of the parasitic gears 10 are fixed on the gear 14 mounted loosely on the fixed axis of the rotor 15, on which the gear 8 is fixed. The diameters of the gears 8, 9 and 10 are the same, as a result of which the gears 9 and 10 are rolled around the gear 9 and the spatial position of the housings 12 bearing spring-loaded rods 13 with needles 5 will be unchanged. The gear 14 is driven by the drive 16 by means of gears 17 and 18. Free rotating rollers 19 are also fixed on the rods 13, interacting with stationary copiers 20 and a vertical arm pivoting lever 21 made in the form of a two-arm lever mounted in the interaction zone. needles 5 with upper newspaper 2 of foot 3. One arm 22 of the lever is connected to the drive 23, and the other 24 (fork), with the drive 23 turned on, is aligned with the copiers 20 and together with them serves as a stop for the rollers 19.

The mechanism 4 for feeding the foot to the needles 5 is made in the form of a vibrating table 25, on which newspapers 2 are mounted with ends, and a movable support 26 for moving the foot 3 of newspapers 2 along the vibrating table 25 to the needles 5, means of single-piece gripping and separating newspapers from the foot 2. Vibration is transmitted to the table from the actuator 27 by means of a spring-loaded stem 28 and an eccentric 29. The stationary stop 26 is adapted to move by means of wheels 30 via guides 31 and has a protrusion 32 for bending newspapers 2 in foot 3 in the area of their interaction with needles 5. To provide the necessary pressure newspapers 2 3 nN for limiting abutment 33 of vibration table 25 movable abutment 26 is balanced by the load 34, and 3 stypy newspapers springs 35 wt.

The discharge conveyor 6 is made in the form of driving belts 36 and 37, between which 3 newspapers 2 separated from the foot are transported to the hopper 38. Aligners 39 of newspapers are installed on the sides of the vibrating table 25.

The device works as follows.

Take the movable stop 26 and the vibrating table 25 between the stop 26 and the cutting edge 33 set 3 newspapers 2 on the end of the foot. Then the stop 26 is released and the foot 3 is pressed against the stop 33 by means of the protrusion 32. Next include the drives of the discharge conveyor 6, the vibrating table 25, gears 14, levelers 39 and pivot arm 21.

f

The foot 3 becomes movable, the adhesion between its constituent newspapers 2 decreases, and the foot itself levels off. The arm 24 of the lever 21 is aligned with the copiers 20. The gears 9 and 10 run around the fixed gear 8, the housing 12 with the rods 13 and the needles 5 placed inside them move in a parallel plane around the circumference above the foot 3 in its middle part, and the rollers 19 roll along the copiers 20 and the forked arm 24 of the lever 21 keeps the rods 13 from advancing from the housings 12 and do not allow the needles 5 to interact with the upper newspaper 2 of the foot 3. By a command from a software device (not shown), the actuator of the rotary lever 21 is turned off and its exclusive play About 24 is removed from the copiers 20. During the rotation of the jaws 14, the rollers 19 fixed on the rods 13, roll over the copiers 20, are torn from them, and the rods 13 with needles 5 sharply protrude from the hulls 12. The needles 5 sequentially pierce the upper newspapers 2 feet 3 and continuing to rotate along with gear 14, they supply separated from foot 3 newspapers 2 into the gap between tapes 36 and 37 of diverting conveyor 6. Separate each subsequent newspaper 2 from foot 3 is made after displacing the previous one outside its zone of interaction with needles 5. Separated from foot 3 newspapers 2 n are given in the outlet conveyor 6 in cascade. The separation of the newspapers 2 from the foot 3 stops when the drive of the pivot arm 21 is disconnected.
