Abstract
The utility model relates to a device for detecting broken center wire of steel strand. The device comprises an infrared device (5) mounted on the outer side of a broken wire ring (1), and a control circuit connecting signals with the input terminal and the 24 V terminal of a PLC through an output control point (4) of a relay of the infrared device (5). The utility model changes a point detection manner into a face detection manner through the infrared device mounted on the outer side of the broken wire ring, thereby detecting whether the center wire is broken or not accurately. The detection device has high reliability and can control a wire twisting machine to stop operating in time, thereby reducing the material consumption and improving the yield of finished products.
Description
Technical field
The utility model relates to a kind of device that steel strand wires central hair fracture of wire is detected.
Background technology
At present, wire twisting machine in order to guarantee the quality of steel strand wires, is provided with fracture of wire ring pick-up unit in the central hair position of steel strand wires in production run.Because what this kind device adopted is a detection mode; just can't detect when fracture of wire breaks before the fracture of wire ring sometimes; the blind area often takes place so in process of production to be detected; can not detect the fracture of wire situation of central hair exactly and send halt command in time; thereby caused the unnecessary loss of material, reduced the lumber recovery of finished product.
Summary of the invention
Problem to be solved in the utility model provides a kind of pick-up unit, can detect the situation that fracture of wire takes place central hair aborning exactly, makes wire twisting machine stop to produce.
The pick-up unit of steel strand wires central hair fracture of wire of the present utility model, a kind of pick-up unit of steel strand wires central hair fracture of wire is characterized in that: it comprise the infrared facility 5 that is installed in fracture of wire ring 1 outside, with signal by infrared facility 5 relays output reference mark 4 and the input end of PLC and 24V between the control circuit connected.
The utility model is by installing infrared facility in the fracture of wire ring outside, and the detection mode of changing the time is detection mode, has or not the fracture of wire phenomenon thereby can detect central hair exactly.Because this pick-up unit reliability height, it is out of service to control wire twisting machine in time, has reduced the loss of material, has improved the lumber recovery of finished product.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the pick-up unit of the utility model steel strand wires central hair fracture of wire.
Embodiment
As can be seen from Figure 1, the pick-up unit of steel strand wires central hair fracture of wire of the present utility model comprises two parts: a part is an infrared facility 5, and it is made up of infrared transmitting tube 2 and infrared receiving tube that symmetry is installed in fracture of wire ring 1 outside: another part for signal by infrared facility 5 relays output reference mark 4 and the input end of PLC and 24V between the control circuit connected.The output reference mark 4 of relay wherein can be relay normally open contact or normally closed contact.
The principle of work of the pick-up unit of steel strand wires central hair fracture of wire of the present utility model is: when the situation of fracture of wire appears in central hair 1; infrared receiving tube 3 and power valve 2 are input to infrared facility 5 with detected signal; send output reference mark 4 work that instruction makes relay by infrared facility 5 internal logics; detect the action command at the output reference mark 4 of relay by PLC; send the logical order of shutdown after the conversion of PLC internal processes controller, thereby reach purpose because of the fracture of wire auto stop.
Claims (3)
1. the pick-up unit of a steel strand wires central hair fracture of wire is characterized in that: comprise the infrared facility (5) that is installed in fracture of wire ring (1) outside, with signal by infrared facility (5) relay output reference mark (4) and the input end of PLC and 24V between the control circuit connected.
2. pick-up unit according to claim 1 is characterized in that: described infrared facility (5) is made up of infrared transmitting tube (2) and infrared receiving tube (3) two parts, and symmetry is installed in the outside of fracture of wire ring (1).
