Description

The invention relates to mechanical engineering, in particular, to means of automation of technological processes, and can be used when loading assembly machines and for automating the supply of ferromagnetic parts for machining or control.

The purpose of the invention is to increase the productivity of orientation of long cylindrical parts by using the energy of the field of a pulse-switched electromagnetic coil, covering an oriental chute, made in the shape of a polyhedron.

FIG. 1 schematically shows a device, a general view; in fig. 2 is a view A of FIG. ; in fig. 3 is a view B in FIG. one.

The device consists of a vibrating hopper 1, a feeding chute 2, a housing 3 with an orienting chute 4, a guide channel 5 in which a pusher 6 is installed with the possibility of reciprocating movement, a refocusing electromagnet 7 and a tapping chute 8.

The feed tray 2 is installed with a slope (5-10 °) with respect to the output part of the tray of the vibrating hopper 1. The housing 3 is made in the form of a pulse-activated electromagnetic coil, which covers the groove 4 of a nonmagnetic material. The chute 4 has a bottom with a hole corresponding to the diameter of the part, and is made in the shape of a polyhedron, for example, of a triangular shape, on one side of which (opposite the hole) a ferromagnetic insert 9 is mounted.

The shape of the gutter (its cross section) 3.) hangs on the required number of flows of the orienting parts. If one flow is required, it is made of a triangular shape, with one hole in the bottom, which is made in one corner with one insert located on the opposite side of the hole. If it is necessary to create two streams, then the shape of the gutter 4 is quadrangular, etc.

The dimensions of trench 4 (its cross-section) depend on the size of the orientable ferromagnetic details and the required number of details in the batch falling into the chute 4. The parts should be positioned in it nod. Juno, resting on the walls of the chute 4, but not horizontal IHc, i.e. lying on the bottom.

where is the length of the part; ct is its diameter;

° C - the angle of inclination of the part installed in the gutter, the optimal value of which is 50-60 °.

Chute 4 may be in the form of a cylinder, then the liner 9 is located along the generatrix and has a cut (open) corresponding to the diameter of the part. In general, the shape of the gutter should be such that the gradient of the field is directed toward the hole in the bottom of the gutter 4, i.e. output channel.

The guide channel 5 is installed under the hole in the groove 4 and has a diameter somewhat larger than the diameter of the oriented part (less than two diameters of the part). In the guide channel 5, an emphasis 10 is installed. Its diameter is less than the internal diameter of the workpiece hole so that

5 so that the detail, going bottom up, is loosely worn on it. A notch 11 is made in the guide channel 5. Its width is larger than the diameter of the orientable part, and the distance ti from the upper plane of the abutment to the edge of the notch is less than the length of the part. In the guide channel 5 and in the area of the stop 10, there is a holding permanent magnet 12 and a sensor 13 for the presence of the part in the guide channel 5.

In the cut-out zone 11 behind the discharge tray 8

5, a C-shaped electromagnet 7 is mounted at a distance a from cut-out 11, which provides a reversal of the part and hitting it into the wire channel formed by the poles 14 at an angle that does not allow the magnetic force lines to turn the part and

0 w in it at any end, i.e. the part is positioned with respect to the electromagnet 7 at a small angle to the vertical at the moment the pusher operates.

The sensor 13 for the presence of the part is electrically connected to the drive of the pusher 6 (for example,

an electromagnet) and an electromagnet 7. Case 3, channel 4 and guide 5 are installed at a small (2-5 °) angle to the horizon, which ensures optimal conditions for the installation and advancement of the component being oriented.

The discharge chute 8 is either installed under the electromagnet 7, or is an extension of the passageway formed by the poles 14.

The device works as follows.

Ferromagnetic parts, which are primarily oriented in vibrating hopper 1, flow out of it (in one or several streams) and fall into the receiving 0 tray 2. The inclination of the tray 2 ensures the separation of the batch of parts from the continuous flow. Parts of the parts fall into the magnetic chute 4. A pulsed electromagnet of the coil 3 is turned on, and the parts fall into the opening of the chute 4 one by one, thanks to the creation of a non-uniform field and its localization in this very corner. Magnetic field lines act on the part so that it is installed vertically above the opening
