Description

Cutting machine of embroidery machine {The cutting thread sensor of embroidery machine}

The present invention relates to a thread cutting device of a embroidery machine, and when the thread is cut during the embroidery process, the LED blinks on the LED display window and the sound of a speaker sounds so as to detect the primary thread cutting detection zone and divide the primary unit zone. The LED blinker blinks at the cutting off point to find and repair the cutting off point so that the embroidery can be removed.

Embroidery machine is supplied individually to the embroidery needle 1000 ~ 1500 needles to operate simultaneously in the pattern set on the plain to perform embroidery on the fabric.

If any one of the 1500 embroidery yarns supplied to the embroidery needle is broken in such an embroidery machine, a defective part that cannot be embroidered is formed on the broken part, so that the work is required to correct it and the quality of the work is required a lot of time. This falling defect has been.

Cut-off detection device to solve this problem is equipped with LED display window and speaker on PCB circuit, pulse generator and detector are installed on embroidery machine. It blinks on the display window to remind you of the cut off.

Such a conventional cut off detection device has a large contact area by the present application in order to solve this problem because a malfunction occurs when the embroidery thread is disconnected from the sensing unit (detection zone) that detects the embroidery thread. Cut-off detection device (Domestic Utility Model Registration No. 235233, registered on June 11, 2001) has been invented to improve the malfunction by forming an arc-shaped coupling groove.

Such a conventional embroidery thread cutting detection device is used to set 80 to 100 embroidery yarns in one unit area in the display window of the LED.

This means that when the embroidery thread is cut in the embroidery machine, the LED display window blinks and the speaker sounds, and the worker finds the thread cut at that point and connects to the thread.

At this time, it is time consuming to find the cut off point at 80 ~ 100 cutoff points, and it is impossible to find the cutout point.

Therefore, the present invention improves the conventional defects, and when the zone of the cutting point is displayed on the LED display window, the operator checks the cutting zone and goes to the cutting unit area displayed on the LED display window, and then cuts the cutting zone again and sets the secondary cutting. It is an object of the present invention to provide a cutout detection device that can quickly find the embroidery thread that is cut off by causing the LED blinker of the cutout point to blink in the area.

Couplings (8a) of the sensing sphere (8) provided with a coupling spring (8a) on one side, the coupling member (8a) on the other side, the coupling rod (8) on one side of the conductive rod (4) In the conventional electronic sensing device which is formed by inserting the auxiliary conductor rod 10 on the front side of the conductive rod 3 located between the bottom plate 2 and the top plate 2a, and the LED fixing groove on the tip side of the bottom plate 2, respectively. A pair of ground recesses 13 are formed to accommodate the LED blinking holes 12 to be housed, and to simultaneously pick up the conductive rods 3 and the auxiliary conductive rods 10 at the curved connection portions of the sensing holes 8. The proximity switch 14 may be connected to the auxiliary conducting rod 10 so that the LED blinking hole 12 may blink when the sensing earth 8 is grounded. So that is one configuration.

In the drawings, reference numeral 20 denotes embroidery yarns, and a and b denote secondary cutoff detection zones.

Referring to the effects of the present invention configured as described above are as follows.

The auxiliary pulse generating unit and the auxiliary detecting unit are additionally installed in the block diagram of the cutting sensor as shown in FIG. 5 to form a block diagram of the cutting sensor as shown in FIG. 4, and the auxiliary pulse generating unit as shown in FIG. The auxiliary sensing unit is configured to be connected to the auxiliary conductive rod 10, and the embroidery thread 20 is inserted into the embroidery guide 8b of the sensor 8 as shown in FIGS. Embroidery will be performed.

In other words, if the embroidery thread 20 of 1000-1500 strands maintains tension on 1000-1500 embroidery needles connected to the embroidery machine, embroidery is carried out. (8) is a pair of ground groove (13, 13a) located in the sensing opening (8) while falling down around the conductive rod (4) is connected to the conductive rod (3) and the auxiliary conductive rod (10) It is grounded and detected by main pulse generator and main sensing part due to grounding of sensing hole (8) and conductive rod (3). Then, LED of grounded primary cutoff detection area of LED display flickers and speaker notifies cutting off. On the other hand, the proximity switch 14 connected to the auxiliary conductive rod 10 due to the grounding of the sensing hole (8) and the auxiliary conductive rod 10 is a secondary that is located at the point that is detected and cut off by the rotary sensing sphere (15) LED blinking port 12 of the cut off detection area is flashing to inform the cut off point.

Because of this, when the operator checks the zone of the cutoff point in the primary zone and finds the cutoff zone, the operator cuts the primary detection zone again into the LED fixing groove 11 of the insulator base plate 2 of the secondary cutoff detection zone. The embroidery thread of the sensing sphere 8 is found by detecting the broken embroidery thread in the conductive rod 3 and the auxiliary conductive rod 10 of the flashing LED flashing sphere among the several LED flashing holes 12 located. When inserted into the guide (8b) and connected to the embroidery needle and the tension is caught, the sensing sphere (8) is restored to the ground state is released from the conductive rod (3), the auxiliary conductive rod (10).
