The working part of the stop 6, made in the form of a bracket 8 with a pocket 10, In the lower and upper corners of the bracket 8 are installed sensors to monitor the availability of parts. If the part has entered into the bracket 8, occupying a position in which the supporting planes of the arches of its arc are facing downwards, then it falls into the pocket 10 of the bracket 8. The axis of its orifice descends relative to the stop 6 and coincides with the axis of movement of the secondary orientation mechanism pin 18 with the possibility of reciprocal post-1 displacement on the horizontal plane, perpendicular to the 11: 1 axis of the tray. At the command of the sensor, an electric motor is turned on, the shafts 24, 17 and 22 coming into rotation. A cam 21, acting on the finger 18, inserts it into the hole of the part. Next, the cam 16 and the spring 7 from the stop 6 back from the tray. At the same time, through the roller 13, the movement from the anvil 6 is transferred to the slam-shut 14, it moves forward to the tray, the compartment of the part 8 in the bracket 8 from the main flow. As a result of moving the support 6 backward, the clip 8 of its working part leaves the part located inside it and it hangs freely on it. Next, the cam 21 and the spring 20 return the finger 18 back to its original position. With this, the part, resting against the front edge of the abutment 6, is removed from the finger and enters the cassette 25. The cam 16 returns the abutment 6 and the slam-shut 14 to its original position. If the part occupies a position in 8 working part of the support, at which the reference planes of the shoulders of its arc are facing upwards, then when the support 6 moves backward, it turns relative to the finger 1 8 to I 80 and is thrown into the cassette 25 in the reoriented position. 3 Il.

FIELD OF THE INVENTION The invention relates to mechanical engineering and can be used with LD1N tzgatuchnoy oriented issuance of parts.

The purpose of the invention is to expand the technological capabilities of the device by providing the possibility of piecewise oriented delivery of arcuate parts with a hole located in its transverse plane of symmetry.

FIG. 1 shows the device, a general view; FIG. 2 is a section A-A in FIG. one; Fig. 3 shows the design of the working part of the rolling stop.

The device contains a vibrating hopper 1 with a feed tray 2, above which

at a height slightly higher than the height of the orientated parts 3, a visor 4 is mounted. Outside the vibration hopper, a base 5 is mounted, on which is mounted with the possibility of reciprocating movements in the horizontal plane perpendicular to the axis of the feed tray, the stop 6, is spring-loaded relative to the base 5;

The working part of the stop 6 is made in the form of a bracket 8 and a pocket 10 adjacent to its jumper 9, In the upper corner of the bracket 8 and in its pocket 10 sensors 11 and 12 are installed, respectively, to control the presence of the part. The stop 6, via the roller 13, is kinematically connected to the slam-shut 14. That allows them to carry out a simultaneous reciprocating motion relative to the base 5, and in opposite phase one relative to the other. The stop 6 through the pusher 15 is kinematically closed on the cam 16 mounted on the shaft 17. The secondary orientation mechanism of the parts is made in the form of a finger 18 mounted in front of the vertical bridge of the working part of the stop 6 in the guide 19 fixed to the base 5. The finger 18 by means of a spring 20 spring-loaded relative to the guide 19 and kinematically closed on the cam 21 mounted on the shaft 22. The shafts 17 and 22 are connected to the drive shaft 24 via bevel gears 23.

.the working part of the stop 6 on the base 5 is installed cassette 25,

The device works as follows.

The parts 3 are transported in one row in a continuous flow through the feed chute 2 of the vibration hopper. Due to the visor 4 mounted above tray 2, they occupy two positions on the tray: leaning on the working surface of the tray with the reference planes of the arc arms or in contact with the working surface of the tray with the curved surface of their arc, and at the same time abutting the peak And the reference plane of one of the shoulders of its arc. From the tray, the parts enter the bracket 8 of the working part of the stop 6 and rest against its vertical nepeMi niKy. If the part occupies the first of these positions, then it falls into the pocket 10 of the bracket 8 with its front part. coincides with the axis of movement of the finger 18 of the secondary orientation mechanism. Further, according to the signal from sensor 12, an electric motor (not shown) is turned on, which completely rotates the drive shaft 24 and through the gears 23 — shafts 17 and 22, the Cam 21 acts on the pin 18 and, compressing the spring 20, enters the hole of the part it is resting on it. Then, as the blade 17 rotates, the cam 16 begins to contact the pusher 15 in a decreasing radius. The extended springs 7, the closure of the pusher 15 on the cam 16, are reduced and move the stop 6 backwards. At the same time, through the roller 13, the movement of the anvil 6 is transferred to the cutter 14 and it moves forward to the tray and cuts off the front part located in the bracket 8 from the main part stream. As a result of the movement of the stop 6 backwards, the staples 8 of its working part comes out from under the part in it and it hangs freely on the finger 18, occupying a horizontal position. Further, as the shaft 22 rotates, the cam 21 contacts the pin 1B along the decreasing radius and the spring 20 closes the cam to the cam, returns it back to its original position. At the same time, the part, resting against the front edge of the working part of the stop, is removed from the finger and enters the cassette 25. Then the cam 16 returns the stop 6 forward to its original position, and the slam-shutter 14, respectively, rearward. Further, tmcl is repeated.

If the part occupies the clip 8 of the working part of the stop 6, the second of these positions, then the stop, cutter and secondary orientation mechanism starts at the command of the sensor 11 and proceeds as described above. In this case, after moving the stop back, the part turns on the finger 180 the horizontal position of the support planes downwards, and after secondary orientation also enters the cassette 25,
