Abstract

The utility model discloses a device for controlling the supply of an insert part based on the principle of neutral wire ground connection, which comprises an insert part supply conveyor belt, a motor, a speed reducer, an induction head, a control circuit and the like. The device is characterized in that the control circuit is a DC circuit formed by the series connection of a contact switch, a DC power source and a relay. The relay is actuated or stopped by virtue of the on/off of the control circuit, so as to control the conveyor belt and the motor to work and thus to control the supply of the insert part. As the control component of the automatic supply device achieves the purpose of controlling the operation of the motor by virtue of the on/off of the DC circuit, and the induction head is made of steel and can not be burnt by the insert part with high temperature (300 DEG C), the utility model solves the problems in the prior art that the electronic induction control equipment is usually burnt by the insert part with high temperature and fails to ensure the normal supply of the insert part, increases the running efficiency of the equipment, reduces the equipment failure rate, and achieves significant economic benefit.

Description

A kind of device that utilizes zero line ground connection principle control inserts to supply with

Technical field

The utility model relates to a kind of inserts feedway, is specially a kind of device that utilizes zero line ground connection principle control inserts to supply with.

Background technology

In die casting during inserts, must be heated to inserts more than 300 about degree in the production, by the inserts feeding mechanism, be transported to the position that manipulator can be got then.Be with electronics inductive head induction inserts in original technology, with the switching of control relay, thus the supply of control inserts.In the production of reality, because the inserts temperature is very high, the electronic induction head is easily by roasting bad, thereby causes supplying with unusual, and fault rate is high and influence is produced, even damages machine.

Thereby prior art awaits to improve and improve.

The utility model content

The purpose of this utility model is to provide a kind of new inserts feedway, and this device can be supplied with situation according to inserts and be switched on or switched off inserts supply conveyer belt motor power circuit automatically, is not subjected to temperatures involved.

The technical solution of the utility model comprises:

A kind of device that utilizes zero line ground connection principle control inserts to supply with, comprise that inserts supplies with conveyer belt, electric motor, reductor, inductive head, control circuit, wherein: described control circuit is the DC circuit that contact-making switch, dc source, relay three are composed in series.

The device that described control inserts is supplied with, wherein: described contact-making switch comprises a resistant to elevated temperatures contact induction head.

The device that described control inserts is supplied with, wherein: described dc source is the 24V dc source.

The device that described control inserts is supplied with, wherein: described 24V dc power anode connects relay, and connects inductive head through relay; Negative pole connects the contact-making switch other end.

The device that described control inserts is supplied with, wherein: the action of described conveyer belt is to control by the break-make of relay control motor circuit.

The technique effect that the utility model produces is: this automatic supplier is to replace the induction of electronic induction head with the DC circuit through and off, controls the supply action of inserts feeding mechanism.Simple in structure, control is sensitive reliable, is not subjected to the inserts temperatures involved, has reduced fault rate, has improved production efficiency.

Fig. 2 is the utility model structure (overlooking) schematic diagram;

Fig. 3 is the utility model structure (main looking) schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, illustrate that structural principle of the present utility model is as follows:

Shown in Fig. 2,3, structure of the present utility model comprises inserts supply conveyer belt 2, motor 7, reductor 8, conveyer belt control circuit etc.Inserts 1 moves on conveyer belt 2 during work, and when arriving the precalculated position, when promptly contacting with control circuit inductive head 3, control circuit is connected, relay J 1 action, and the power supply circuits of disconnection motor 7, motor 7 stalls, conveyer belt 2 is out of service.Among Fig. 2,4 is terminal screw, and 5 is gripper shoe, and 6 is compact heap.

As shown in Figure 1, the conveyer belt control circuit is the DC circuit that comprises that contact-making switch K1, dc source E, relay J 1 three are composed in series.

Contact-making switch K1 is the contactor of connecting when being moved into place by inserts.Comprise two kinds of forms:

1, two point form contact-making switch: promptly the positive pole of power supply is connected on the contact-making switch K1 inductive head (1 point) by relay J 1 line bag, and negative pole is connected on another contact of contact-making switch, has only when inserts 1 to be sent to certain position, connects this 2 point, and control circuit is just connected,

2, a point type contact-making switch: the positive pole of power supply is connected on the contact-making switch K1 inductive head (1 point) by relay J 1 line bag, power cathode (zero line) is connected with inserts 1, conveyer belt 2 chain ground connection, inserts 1 is seated on the conveyer belt 2 and contacts with zero line, be equivalent to inserts 1 and connect power cathode, as shown in Figure 2.When inserts 1 moves into place when touching inductive head, control circuit is connected.

Operation principle of the present utility model is:

Inserts and direct current 24V zero line are joined, and dc power anode joins by relay J 1 and inductive head, when inserts 1 heats through holding furnace, be delivered to and inductive head 3 contacted positions, closing of circuit, relay J 1 closure by conveyer belt 2, motor 7 stops operating, and inserts 1 is supplied with and stopped.

The utility model is controlled electric motor action by the break-make of control circuit, and when inductive head 3 is run into inserts 1, DC circuit connects (quite switch J1 closure among Fig. 1), relay J 1 energising, the contact of control electric motor 7 connecting and disconnecting of the circuit disconnects, motor 7 stalls, and inserts 1 is supplied with and is stopped.When inserts 1 is taken away by manipulator, circuit disconnects (quite switch J1 opens among Fig. 1), relay J 1 outage, and the switch closure of control electric motor 7 connecting and disconnecting of the circuit, motor 7 work, inserts 1 is supplied with and is started.

In sum, the utility model is based on the defective of original technology, now adopt zero line ground connection principle to respond to inserts,, control the supply of inserts then by the break-make of relay place DC circuit, this moment, the material of inductive head can select for use resistant to elevated temperatures conductive material to get final product, can be roasting not bad in the production by the high temperature inserts, thus the supply of inserts can be guaranteed for a long time and normally, obviously improve the running efficiency of equipment, reduce breakdown rate, economic benefit is obvious.

Should be understood that above-mentioned description at specific embodiment is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, scope of patent protection of the present invention should be as the criterion with claims.
