Description

Devices for sorting balls, rollers and similar objects by the size of the outer diameter are already known, with the supply of products coming from the bunker by means of a rotating drum with grooves along the forming and using a sorting device controlled by the controller through electromagnets acting on the doors of the sorting compartments, on the way of sorted products. Such maschines can be used in control and assembly compartments, in mass or large-scale assemblies of assemblies with a large number of cylindrical, conical or spherical parts, in particular balls and rollers for bearings, piston, spring and other fingers, etc.

The novelty of the proposed device lies in the fact that the sector mounted on an axis with an adjustable eccentricity and acting at its turn on a controller located coaxially with it, serves as a gauge in the sorting device. In this case, the controller closes the electromagnet of the sorting device corresponding to its angular rotation, and this is used to isolate specimens of the required size from the total mass of incoming products.

In FIG. 1 shows the general scheme, FIG. 2 - one of the parts of the device.

The products 29 to be sorted are fed into a fixed bunker /, under which the feed drum 2 is located, periodically rotated on axis 3 in the direction indicated by the arrow. This periodic rotation of the drum 2 produces the Maltese cross 4, which sits on the axis 3 of the drum 2 and is driven by a continuously rotating disk 5 and finger 6 (Fig. 2).

The axis 8 is eccentrically mounted on the measuring sector 7 (Fig. 1), whose eccentric position with respect to axis 8 is obtained by the corresponding position of the eccentric 9 or by using

shifting the center of the measuring sector 7 by means of other devices, such as a micrometer screw or the like. In order to avoid wear, the working surfaces of the measuring sector must be chrome-plated.

The lever 10, mounted on the axis 8 (FIG. 2), using a cam // produces periodic turns of the measuring sector, i.e., periodically raising it in the direction of arrow 12 and free lowering in the direction of arrow 13.

On the axis 6 of the measuring sector 7 mounted electrical switch 14 (Fig. 1) controller type. This switch is designed so that, as the measuring sector rotates in the direction of the arrow 13, its conductive part 15 gradually turns on the contacts 16 closing the electromagnets 17; at the beginning of the turn, before the contacts 16 are turned on, the contact 76 closing the group of electromagnets 19 is switched on.

The electromagnets 17 and 19 act on the cores 20, which with the help of tg, moving in the guides 21, and the stops 22, throw the doors 23 to the left or the right. Each of the doors 23 guides the measured part, sliding out of the grooves of the supply drum 2, into the corresponding channels 30 in which the measured part is discharged into a collection corresponding to its diameter.

Inside the drum 2 there is a fixed liner 24 carrying a bearing prism 25 mounted for measuring bodies of different diameters using a micrometer screw 26.

A switch 27 is provided to turn on the electric current. Pins 16 and 18 can be swapped and fixed along insulated axis 28.

The device operates as follows.

The measured parts 29 when turning the engine of the supply drum 2 fall

The jgHS of the bunker is in the grooves of the drum and pushed onto the surface of the prism 25. In

the time of this operation, the measuring sector 7 is retracted in the direction of the arrow 12 using the cam 11 and the lever 10. Then the sector 7 is freely lowered by the force of its weight and stops at one or another position, depending on the diameter of the part 29 located between the prism 25 and the eccentric part of the measuring sectors 7. Accordingly, the position of sector 7, which is located along the common axis 8 with it, switch 14 will also occupy some middle position, at which the corresponding number of electromagnets 17 will be switched on via contacts 16.

Turning on the electromagnets 17 will cause the cores 20 to move to the left and using the stops 22, doors 25 to move to the left. At that, each diameter of the measured part will correspond to the position of one of the doors 23 thrown to the left, and consequently, a certain channel for removal of the measured part.

To return and install all doors 23 to the initial (far right) position, before the start of each measurement, contact 18 is used, which, when the controller 14 is rotated before the start of the next measurement, preliminarily includes a group of electromagnets 19, simultaneously moving all cores 20 and doors 23 to the right. Thus, each dimension of ne depends on the previous position of the doors.

Using the device described above, it is possible to sort products within the limits of the tolerances used in the technique.

The subject matter of the invention.
