Description

t

The invention relates to the automation of technological processes and can be applied in the radio engineering and instrument-making industry when equipment is loaded with 5 non-magnetic current-conducting parts.

A device for contactless orientation of non-magnetic conductive parts is known, comprising an electromagnet 10 and a system for supplying and discharging parts.

one.

It is also known that the device contains an electromagnet with additional ferromagnetic rods and the system fS for supplying and discharging parts 2. .. The disadvantage of this device is its relatively low productivity when orienting parts of various sizes, since the 20 picture of the floor in the electromagnet gap cannot be quickly changed, and the readjustment of the device is associated with the cost of labor and time.

 The invention is an increase in productivity with the orientation of parts of various sizes.

The goal is achieved by the fact that a part recognition unit, a switching unit is inserted into the device; thirty

The Fixing block of the initial position of the rods and the block for extending the rods, the output of the block for recognizing parts through the switching unit is connected to the input of the block for fixing the initial position of the rods and to the input of the block for extending the rods.

FIG. 1 shows the general view of the proposed device; in fig. 2 is a functional diagram of the device; in fig. 3 shows the structure of the extension block of the rods and the fixation block of their initial position.

The device comprises an electromagnet 1 with retractable ferromagnetic rods 2, a system 3 for supplying and withdrawing parts, for example, a conveyor belt, a part recognition unit 4 connected to a switching unit 5, a rod driving unit 6, a rod initial position fixing unit 7. The unit 5 is connected to the unit 6. extending the rods, unit 7 fixing the initial position of the rods and the electromagnet 1.

The unit of recognition of parts has an aerodynamic design, depending on what sign the recognition of parts occurs.

FIG. 2 shows block 4 of a location. parts consisting of a series-connected scanner 8, an adder 9 and a decoder 10. In this case, the parts are recognized by the surface area.

The switching unit 5 includes a dial-up field 11, an alternating current alternator 1H and a switch 13, a direct current source 14 and a switch 15. An alternator 12 of an alternating current through a switch 13 is connected to an electromagnet 1, and a direct current source 14 through a switch 15 is connected to block 7 fixing the initial position of the rods / representing a solenoid. The rod extension unit 6 includes a multi-position relay 16. The outputs of the decoder 10 can be connected to the corresponding inputs of the multi-drive relays 16 by means of a keypad 11.

The device works as follows. .

In the operator's training mode, the outputs of the decoder 10 and the corresponding inputs of the multi-relay relays 16 are switched. In the conventional mode, a part supplied to the orientation zone by the conveyor belt 3 is recognized by the part recognition unit 4. The signal from the corresponding output of the decoder 10 is fed through the input field 11 at the input of the corresponding multi-position relays 16, ensuring their operation. In parallel with the signal from the component recognition unit, the key 15 disconnects the direct current source 14 from the ylenoid 7 and the sliding ferromagnetic rods 2 are fixed in the gap of the electromagnet 1 At the same time, according to a signal from the part recognition unit, the key 13 connects the winding of the electromagnet 1 to the alternating current generator 12.

Keys 13 and 15 maintain the operating mode for the time required for the approach to the zone

orientation and its orientation. Further, the keys transfer the circuit to the initial position, i.e. the alternator 12 is disconnected from the electromagnet 1, the rods 2 are retracted. The solenoid 7 and the oriented part are removed from the orientation zone.

The use of the proposed device in comparison with the known one allows to obtain the following advantages; increase in productivity due to the exclusion of readjustments of the device, especially in the conditions of serial and small-scale production, more rational expenditure of electricity and, as a result, a decrease in the relative cost of the device per item.
