Description

 The invention relates to the automation of technological processes, can be used to control, orient and sort asymmetric parts.

 A device for sorting parts containing discharge chutes, a restriction curtain, a conveyor chain and an ejector connected through a system of levers with a drive is known.

The known device has the following disadvantages:
can be used only for a certain type of parts (inserts), i.e., technological capabilities are limited;
the design does not provide for the possibility of orientation of parts, i.e., limited functionality;
the presence of a large number of levers and their kinematic relationship complicates the design and reduces the reliability.

 A prototype of the proposed method and device for its implementation is a method for separating the flow of conical parts and a device for its implementation, which consists in sequentially moving parts along an inclined guide tray, separating the flow and diverting incorrectly oriented parts from the stream after they leave the tray with the help of a stop. A return stop is installed between the inclined inlet and outlet trays.

The known method and device for its implementation have the following disadvantages:
can be used only for a certain type of parts (conical parts - rollers), i.e. technological capabilities are limited;
the design uses the principle of diverting incorrectly oriented rollers from the flow and returning them again to the inclined feed tray for re-orientation. The newly fed rollers for reorientation can again be diverted from the stream, etc. Therefore, performance is reduced.

The objective of the invention is:
expanding technological capabilities by expanding the range of oriented parts;
increased productivity by eliminating the removal of incorrectly oriented parts from the flow.

 In FIG. 1 shows a device for implementing the method, General view; in FIG. 2 is a view along arrow A in FIG. 1; in FIG. 3 is a view along arrow B in FIG. 1; in FIG. 4 is a section BB of FIG. 1; in FIG. 5 - orientation mechanism; in FIG. 6 - some orientable details (for example).

 The device for orienting parts contains inclined inlet 1 and outlet 2 trays. Between trays 1 and 2, a device 3 for supplying compressed air and an orientation mechanism for parts 4 are mounted. The orientation mechanism is made in the form of a freely swinging shutter 5 with an axis 6 and a pivoting platform 7 with an axis 8 and an actuator 9. The shutter 5 is equipped with a sensor 10 included in the electric drive control circuit 9 of the platform 7. The platform 7 is mounted on the bearing 11, and the shutter 5 with the axis 6, having a screen 12, on the frame 13. Above the frame 13 is mounted on the housing 14 a fixed bowl 15 for parts 4. In the bowl 15 on the bearing 16 is installed agitator disk 17 with an axis 18 and a drive 19. The disk 17 has through curly grooves 20 equally spaced along its outer diameter. The bowl 15 also has a through figured hole 21, under which a tray 22 is mounted connected to the tray 1. The tray 1 has a two-arm lever 23 with a large 24 and a small 25 shoulders and a drive for its rotation (not shown). Under the tray 1 there is a pusher 26, and behind the tray 2 there is a platform 27. Part 4 may have a different configuration, for example, 28, 29, 30, 31.

 The method of orientation of the parts and the operation of the device is as follows.

 Parts 4 are loaded into the bowl 15 on the housing 14, include a drive 19, which rotates the agitator disk 17 through the axis 18 on the bearing 16. When the disk 17 rotates, the parts fall into the grooves 20 and are transported until the groove 20 coincides with the hole 21. The part 4 fails into the hole 21 and moving under its own oar on the tray 22, it enters the tray 1. The disk 17 rotates in this way until the tray 1 is filled with parts 4, while they can be placed in an asymmetric end in different directions. From the sensor signal (not shown in the drawing), the drive 19 stops, and the rotation drive (not shown in the drawing) of the lever 23 turns it and the shoulder 24 is set to the “1” position on the platform 7, and the shoulder 25 picks up part 4. Detail 4 moving along the shoulder 24, it is installed on the platform 7, and the lever 23 returns and gives a signal to the drive 19. The next part 4 moves to the tray 1, and the extreme part in the tray 1 moves to the shoulder 25, the drive 19 is turned off. Part 4 was installed on the site 7 with the asymmetric part to the side of the device 3 for supplying compressed air (Fig. 1), the compressed air supply to the part 4 is turned on. The air flowing around the asymmetric part of the part acts on the curtain 5. The curtain 5 rotates on the axis 6 frame 13 and takes the position "D", while the screen 12 acts on the sensor 10. The signal from the sensor 10 is supplied to the actuator 9, which through the axis 8 rotates the platform 7 on the bearing 11 together with the part. The air supply is stopped and with the help of a collider 26, the part 4 moves along the tray 2 to the platform 27 in an oriented position. From site 27, part 4 is fed further into the process.

 Detail 4 was installed on the site 7 end to the device 3 (Fig. 5), compressed air is supplied, which diverges to the sides, does not affect the curtain 5 and the platform 7 remains stationary. The pusher 26 moves the part along the tray 2 to the platform 27 to the "E" position. After releasing the platform 7 from the part, the lever 23 is again rotated and delivers the next part. Similarly, technological operations can be carried out with other parts, for example, with parts 28, 29, 30, 31, etc.

The proposed method for orienting parts and a device for its implementation allow:
to orient parts having different types of surfaces, for example, conical, cylindrical and others, as well as having a different shape of the asymmetric part of the part, for example, conical, spherical, with a bevel, conical, etc., which expands technological capabilities;
to exclude from the technological process the removal from the flow of incorrectly oriented parts that return back to their orientation. Their return can be repeated, which increases the time of the entire orientation process and reduces productivity. (56) Copyright certificate of the USSR N 1405898, cl. B 07/06, 1988.
