- view along arrow B in FIG. 2; in FIG. 4 is a section bb in FIG. 2, arranged in the off-position position of the kit; in FIG. 5 - the same, the device is in the position of issuing a set of parts; in FIG. 6 is a section GG in FIG. 2 .:

The device comprises a drive 2 mounted on the basis of 1 with a mechanism for piece-by-piece delivery of parts (FIG. 1), a disk 5 installed in the housing 3 on the axis 4 (FIG. 2,3)

with through slots 6 (Fig. 4,5), under each of which there are installed dampers 7 having a mechanism 8 for moving them (Fig. 6), a step-by-step mechanism 9 for turning the disk 4 (Fig. 2,3) and a receiving mechanism 10.

The drive 2 with a mechanism for piece-wise dispensing of parts includes a hopper, a tray, a piece-cutter 11 connected to the pipeline with an input channel 12 mounted on the housing 3. The drive cut-off 11, made in the form of a power cylinder, is connected to a pneumatic sensor 13 mounted on the mechanism 9 of the stepping rotation of the disk .5 (figure 2) ..

angular steps, and the power cylinder 18 with the rod 19. On the rod 19 of the power cylinder 18 there are dogs 20 and parallel to it, a stop 21 rigidly connected to it, on which the air sensor 22 is fixed, and the dog 20 is installed with the possibility of interaction with the pins 15 and focus 21. The pneumatic sensor 22 is installed with the possibility of interaction with the cams 16, and the pneumatic sensor 13 with the cams 17. The number of cams 16 on the additional disk 14 is one less than the number of pins 15, and the number of cams 17 corresponds to the number of parts dialed into the kit. In addition, a pneumatic sensor 23 is mounted on the housing of the power cylinder 18 with the ability to interact with the focus 21.

The dampers 7 (Fig. 4,5) installed under each of the through sockets 6 of the disk 5 are made in the form of rectilinear gates with through holes 24 (Fig. 5,6) and are installed, in turn, in the radial grooves 25 (Fig. .6) made in the housing 3 with the possibility of moving and alternately aligning its through holes 24 through holes 6 of the disk 5 with the output channels 26, connected by pipelines to the receiving mechanism 10.

The mechanism 8 for moving the dampers 7 (Fig. 6) is made in the form of a disk 27 with tangential grooves 28, mounted with the possibility of rotation due to kinematically connected by a gear ring with a rod-rail of the power cylinder 29 and fingers 30, one end of which each finger is fixed to the corresponding shutter 7, and the other is movably located in the corresponding tangential groove 28.

In the housing 2 above the disk 5 an air collector 31 is made in the form of an open ring groove, closed by a lid with a fitting. At the lower end of the air manifold 31, holes 32 are made that coincide with the axes with the through sockets 6 of the disk 5 and the output channels 26.

The device operates as follows.

At the beginning, a kit of parts is carried out.

In the initial position (Fig. 4), the disk 5 is installed in a position in which its through slots b are installed under the holes 32 of the air collector 31 above the output channels 26 and are separated from the latter by shutters; 7. The additional disk 14, in this case, is in a position in which there is no cam 16 under the pneumatic sensor 22.

Parts from the hopper of the drive 2 through the tray enter the controllable rotation mechanism of the disk 5, controlled by a pneumatic sensor 13, of the disk 5, the shut-off device 11 of the unit delivery.

On command from the control unit, compressed air is supplied to the actuator cylinder 18 (Fig. 2). When the rod 19 of the actuator 18 moves, the dog 20 of the step-by-step mechanism 9 interacts with the pin 15 of the additional disk 14. The additional disk 14 is rotated by a step. In this case, the pin 15, in the initial position, in contact and with the stop 21, makes a movement along the arc and loses contact

5 with him, and at the end of the stroke comes into contact with him again and wedges between him and the dog 20, the movement of the rod 19 is stopped and the additional positioning of the additional disk 14 and the disk 5 is exact. At that, its first through slot 6 is installed under the input channel 12 , and the cam 17, mounted on an additional disk 14, is installed under the pneumatic sensor 13. ... -.

5 By the action of the cam 17 on the pneumatic sensor 1.3, the last command is sent to the shut-off unit 11, which cuts off the first part from the tray and feeds it through the intake channel 12. into the through slot 6 of the disk 5.. .

At the same time, as a result of the action of the stop21 on the pneumatic sensor23, the power switch

5 cylinder 18 on the return stroke. The dog 20, contacting the rear side with the subsequent pin 15, rotates, skipping it and, under the action of the spring, is set in front of the pin 15 in the initial position, contacting simultaneously with the stop

. 21. Moreover, the emphasis 21, moving together with

dog 20, not rubbing contact with the first

pin 15, runs into the subsequent

pin 15, thereby providing a fixed5 bath additional disk 14 when ooz-. gateway movement.

. A pneumatic sensor 22 mounted on an abutment 21, moving with it to its original position, interacts with the first cam 16 of the additional disk 14 and, with the resulting signal, switches the power cylinder 18 to the forward stroke. The dog 20 acts on the pin 15 and rotates the additional disk 14 on the next

5 step, with the next through slot 6 of the disk 5 being installed under the input channel 12, and the cam 17 under the pneumatic sensor 13 for the subsequent submission of the command to the cutter 11 to the cutoff and the second part e. Through slot 6.

The set of parts takes place in one complete revolution of the additional disk 14 with its stepwise movement and stops when the additional disk 14 is set to a position where cam 16 is absent under the pneumatic sensor 21. The number of parts that can be dialed into a group is determined by the number of cams 17 installed on additional disk 14. After completion of the set kit operation, the device is ready for simultaneous delivery.

At the command of the control unit, the power cylinder 29 is actuated. The power cylinder rod 29 rotates the disc 27 with tangential grooves 28.

Placed in the tangential grooves 28 and secured in turn to the shutters 7, the fingers 30, moving in the grooves 28, move the shutters 7 in the radial grooves 25, made in the housing 3, until their through holes 24 are not compatible with the through sockets 6 and output kakalami26, providing details m exit opportunity.

Then, compressed air is supplied to the air manifold 31, which through the openings 32 enters through holes 6, facilitating the movement of parts into the receiving mechanism 10 for their subsequent installation in the assembled product.

Upon completion of the operation of issuing a set of parts of the shutter 7, transfer the vehicle to its original position, overlapping through
