SU753496A2 - Apparatus for sorting parts such as rings and discs by height - Google Patents

Description

The invention relates to mechanical engineering and can be used in any industry where sorting of parts into size groups is necessary.

According to the main author. St. No. 57 8124, there is known a device for sorting parts ^{5 of the} type of rings and disks by height, comprising a loading mechanism mounted on a bed, rotary conical disks and a part puller that is rigidly fixed to the bed between the conical disks and is made in. in the form of a cam with stepped protrusions on its cylindrical surface {Xj.

In this device, the force, jamming ^ of the part between the conical disks is not constant in size, which reduces the accuracy of sorting. ·

The aim of the invention is to increase the accuracy of sorting. 20

This is achieved by the fact that the device for sorting parts such as rings and disks by height has a pusher mounted with the possibility of reciprocating motion along the axis of the skein of the loading mechanism by means of a drive, and a spring-loaded stop with a roller at the end placed between the conical disks mounted on the pusher .

The drawing shows the described device s two projections.

The device contains two conical disks 1, rigidly mounted on the shaft 2, which receives rotation from the drive. The inner ring of the bearing 3 is fixed between the conical disks, and the puller 6 is attached to the outer ring of the bearing using the upper 4 and lower 5 rings. The free end of the puller is fixed to the tray of the loading mechanism 7. The magazine 8 for the sorted parts is also attached to the tray of the loading mechanism ._On the tray, the pusher 9, which receives movement from the drive, moves back and forth. A guide 10 is attached to the pusher, a spring stop is made under it, made in the form of a rod 11 · with a roller 13 mounted on the axis 12. The roller is constantly extended towards the conical disks by spring 14. To dump sorted parts' 5 there is a container 15 divided by partitions into cells by the number of sorting groups.

The device operates as follows. ¹⁰

Parts from the store 8 along the tray 7 with the pusher 9 are moved to the conical disks 1 and are jammed between them. The thinner the part, the closer to the axis of rotation 15 of the conical disks it is jammed. When the force of adhesion of the part to the conical disks exceeds the force for which the spring 14 is adjusted, the part squeezes the rod 11 and begins a gentle movement together with the conical disks until it touches one of the protrusions of the puller located at such an distance from the axis rotation of conical disks, which corresponds to 25 thickness of this part. In this case, the part will fall into the appropriate capacity cell for the sorted parts.
