Abstract

The invention relates to devices for stacking flexible sheet material in a stack and is aimed at improving the reliability and expanding technological capabilities due to the possibility of stacking a flexible sheet material of various sizes in a stack. The use of a load-carrying tape, one end of which is wound on a drum, and the other end secured to a movable carriage, permits a flexible sheet material to be reliably transported and placed in a stack. different sizes. The sheet holding device consists of two pairs of plates 7 and 8, 9 and 10 arranged one below the other, having teeth 12 and valleys 13. The teeth 12 of the plates of one pair (plates 7 and 8) are located against the hollows 13 of the plates 9 and 10 of the other pair. One pair of plates 7 and 8 is mounted on the carriage, and the second is fixed. This allows you to securely hold and stack sheets of flexible material of any configuration. 10 il. .

The invention relates to devices for stacking flexible sheet material in the foot and can be used in leather production, in particular, when laying leather in the foot after they are processed on the pass-through equipment.

The purpose of the invention is to increase the reliability and expansion of technological capabilities.

Figure 1 shows the structural-kinematic scheme of the device proposed; figure 2 is a device, top view; on fig.Z - section aa in figure 2 (on an enlarged scale); figure 4 - section bb in figure 2 (on an enlarged scale); FIG. 3 shows the position of the device carriage in the initial position; figure 6 - the same, at the time of the capture sheet; 7 - the same, in an intermediate position; Fig. 8 is the same at the moment of the interception of the sheet by the device for holding the sheet; Fig. 9 shows the same, in the intermediate position when returning to the initial position; in fig. 10 - the position of the slats of devices for holding the sheet when the carriage approaches to the extreme right position.

The device comprises a frame 1 with guides 2 fixed to the frame with the help of brackets 3.

On the frame 1, in the guides 2 on the traveling wheels A with the possibility of reciprocating motion, a carriage 5 is installed.

The operation of the actuator 6 and ditch II is controlled by a photodata placed in a row on crowns which is fixedly fixed 1, Moreover, the photosensors are lent so that they are hollowed 13 plates at 6 to hold the sheet, p on the carriage 5, when it is in the leftmost ( and lying.

The operation of the I6 actuator and the device (the pneumatic actuator is also controlled with the help of the switches 23 and 24, and the clamp is fixed on the frame 1.

Under the frame 1 there is an abutment table 25,

The device works with time.

The sheet enters from the trans processing machine and between the strips 7 and 8 at 6 to hold the sheet on the carriage 5.

As soon as the edge of the sheet is in a row of photo sensors 21, yes and yes, the pneumatic cylinder 11 and the strips 7 and 8 and the actuator 16 are closed, the gripper 5 is moved from the extreme position,

sheet consists of two pairs of plates 7,

The device also includes a carrier tape 14, one end of which is rigidly fixed on the carriage 5, and the other is connected to a tape accumulation unit implemented in the form of a drum 15.

the belt (drum 5) is carried out from the drive 16 by means of the V-belt drive 17, the chain drive 18 and the chain drive 19. The carriage 5 is connected to the chain gear 19 by means of brackets 20,

The operation of the actuator 6 and the pneumatic cylinders II are controlled by photosensors 21 located in a row on a bracket 22, which is fixedly mounted on the frame 1, and the photosensors 21 are mounted so that they are under the depressions 13 of the plate 6 for holding a sheet located on the carriage 5, when the latter is in the leftmost (initial) position.

The operation of the actuator I6 and the actuating device (pneumatic cylinders 11) are also controlled by means of limit switches 23 and 24 fixedly mounted on the frame 1.

Under the frame 1 there is a lifting and lowering table 25,

The device works as follows.

The sheet enters from the conveyor of the technological machine and exits between the bars 7 and 8 of the fixture 6 for holding the sheet located on the carriage 5.

As soon as the sheet reaches the row of photo sensors 21, a command is given to the pneumatic cylinder 11 to close the strips 7 and 8 and the actuator 16. The slats close, pick up the sheet, the carriage 5 moves from the far left initial position, carries the

As the carriage 5 moves, the sheet rests on the carrier tape 14 from above. Come to the extreme right position.

and

in which the teeth of the 12 lower bars 7

9 of the sheet holding device 6 mutually enter into the valleys 13, and the teeth 12 and the valleys 13 of the upper plate 10 of the holding device 6 are respectively above the E1 shaft 13 and the teeth 12 of the lower bar 7, the carriage 5 acts on the limit switch 24. On its command it turns off actuator 6, unlocked: strips 9 and 10, gripping the sheet, disconnecting strips 7 and 8, loosely; waiting: the sheet, driving the actuator 16 to return the carriage 5 to its original position.

As the carriage 5 moves back to its original position, carrying the tape 14 ,. entering the tape accumulation unit, slides out from under the sheet, one end of which is clamped by slats 9 and 10

The sheet is placed under its own weight on the lifting and lowering table 25.

Approaching the initial extreme left position, the carriage 5 acts on the limit switch 23.

The drive 16 is turned off, the card is stopped, the strips 9 and 10 of the fixture 6 for holding the sheet are opened. The end of the sheet is lowered, the sheet is completely laid on the lifting-lowering table 25.

The use of a continuous carrier tape, one end of which is wound on a drum, and the other end mounted on a movable carriage, allows to transport and stack flexible sheet material of various sizes into a stack. And the use of devices for holding a sheet in the form of a comb allows you to securely hold sheets of any configuration during transportation and stacking of flexible sheet material.
