Description

Sequin braider automatic discharging control device

Technical field

The utility model relates to a kind of servicing unit that is exclusively used in the sequin braider, specifically, relates to a kind of sequin braider automatic discharging control device.

Background technology

The sequin braider is a kind of weaving machinery device that will be woven together as the sequin that ornament is used; its sequin blowing all is by manually-operated sequin to be put into feed pipe now; the shortcoming of this artificial blowing is; because of operational sequence many; make labor strength big; and carelessness arranged slightly; just be prone to blowing not as good as consequently lacking the situation of expecting in the course of work; but machine again can be because of not lacking the material autostop in finishing a course of work; therefore lack the quality that material certainly will influence the sequin assembling-disassembling midway, also can cause weave yarn simultaneously---be the serious waste of main traverse line and auxiliary conductor.

The utility model content

Influence product quality, waste weave yarn and the big problem of labor strength for what solve that existing sequin braider exists because of what carry out manually that the sequin blowing causes; the purpose of this utility model; be to provide a kind of can carry out the sequin blowing automatically and when the long period lacks material for some reason, can in time make the sequin braider automatic discharging control device that autostop is handled; thereby guarantee sequin assembling-disassembling quality, save weave yarn and alleviate labor strength.

Solution of the present utility model is as follows.Referring to Fig. 1 electric functional-block diagram of the present utility model; the utility model is by photoelectric sensing circuit 1; central processing unit 2; serial data is changeed parallel output interface circuit 3; power driving circuit 4; magnetic valve and cylinder control circuit 5 and shutdown executive circuit 6 connect and compose; wherein the induced signal output of photoelectric sensing circuit 1 links to each other with the signal input part of central processing unit 2; the signal input part that one output control terminal of central processing unit 2 and serial data are changeed parallel output interface circuit 3 joins; another output control terminal of central processing unit 2 links to each other with the input control end of shutting down executive circuit 6; serial data is changeed the output of parallel output interface circuit 3 and the signal input part of power driving circuit 4 joins, and the output control terminal of power driving circuit 4 links to each other with the voltage controling end of magnetic valve and cylinder control circuit 5.

The utility model device with foregoing circuit structure matches on being installed to the sequin braider when using, and the photo electric sensitive element in its photoelectric sensing circuit 1 should be installed in the front tube oral area position of the sequin feed pipe of sequin braider; A plurality of magnetic valves in magnetic valve and the cylinder control circuit 5 are installed in the frame rear portion, a plurality of cylinders are installed on the hanging wire support of main traverse line, each magnetic valve is connected with on the same group a cylinder to give the cylinder air feed by tracheae respectively, and cylinder links to each other with the sequin feed pipe to control the conveying of sequin; Also it should be shut down in the executive circuit 6 relevant executive component simultaneously is installed in the control loop of complete machine operation relay and in the complete machine operation troubles indication loop; And should provide with due working power for circuit of the present utility model from the circuitry mainboard.So, in the course of work of sequin braider, after the photo electric sensitive element that is in feed pipe front tube oral area position detects the signal of no sequin material, being entered into central processing unit 2 handles, central processing unit 2 output orders change parallel output interface circuit 3 to serial data, output signal to power driving circuit 4 by this circuit 3, again by the voltage controling end of these circuit 4 output control signals to magnetic valve and cylinder control circuit 5, a plurality of magnetic valves are opened, give cylinder air feed on the same group respectively, each cylinder is respectively by the time of setting, and order promotes and landing, carries a certain amount of sequin with control to feed pipe.On the contrary, detect the signal of sequin material when photo electric sensitive element after, the above-mentioned course of work is just the opposite, magnetic valve can cut out and stop to the cylinder air feed, cylinder will suspend control and carry sequin to feed pipe.When for some reason in long period (this time can be set by central processing unit 2 according to production technology) during no sequin material; central processing unit 2 can the output control signal be given shutdown executive circuit 6; remove to disconnect the control loop that complete machine moves relay line bag by shutting down executive component; automatically stop the operation of machine; executive component also can make complete machine operation troubles indication loop make indicating fault simultaneously, in time makes corresponding processing to remind operating personnel.

The beneficial effects of the utility model are, can control the sequin blowing automatically and precise control errorless, therefore can save operator's complicated work, and guarantee that the steady quality of assembling-disassembling is reliable, also accomplish to save production cost because of the waste that can not cause weave yarn; When machine caused the long period to lack material for some reason, it can in time be made autostop and handle and indicating fault, reminded the operator in time to handle, and reduced breakdown loss.
