Referring to FIG. 3, an embroidery machine single yarn display method using a needle bar according to an example of the present invention will be described. The embroidery machine 10 includes a plurality of head parts 30, and each head part 30 includes a plurality of needle bars ( 66 and each needle bar is equipped with one needle 68.

The embroidery thread 40 is sewn to the needle 68 of each needle bar 66. In the process of producing embroidery by loading the selected design pattern, the embroidery machine sews the embroidery thread of the designated color at the designated position on the X Y coordinate of the fabric to produce a pattern.

The embroidery machine moves the frame where the fabric or fabric is fixed in the X-axis and Y-axis directions and transfers it to the desired position on the two-dimensional plane while the needle bar of the head for embroidering moves up and down. It is a machinery that produces automatically.

In general, a single-head embroidery machine in which one head part is connected to one power shaft is called a single-head embroidery machine, and a embroidery machine in which different head parts are connected to two different power shafts is called a dual embroidery machine. Head portion As an example, the connection of 12 to 48 head portions to one power shaft and simultaneously driving the same is called multi-embroidery. Dodu embroidery machine has high productivity because it simultaneously mass-produces embroidery by the same pattern design.

Each head of the embroidery machine is provided with 6 to 12 needle bars, only one needle bar is selected and driven, and each needle bar is equipped with a different color embroidery thread to produce color embroidery of various designs. Each head of the embroidery machine has a significant impact on the quality of the embroidery produced when any one of the plurality of embroidery threads provided is broken, thus detecting the breakage of the embroidery thread (hereinafter referred to as 단). Display technology is an important issue.

The single yarn detection of the embroidery thread in the embroidery machine detects the tension of each embroidery thread and identifies and marks it as single yarn when normal tension is not detected. If any embroidery thread of a specific head is single threaded in a multi-head embroidery machine, all heads driven by the same axis are stopped, and the head of the embroidery thread is warped so that the operator can easily identify and confirm the head. It is easy to check whether the embroidery thread is single threaded and has the advantage of quickly reconnecting or connecting the broken embroidery thread. However, it is common for workshops that produce embroidery to shed light on the threads for clarity and for a clean work environment.

If a single yarn that cannot be supplied to the embroidery thread occurs in the designated needle bar of the embroidery machine, the embroidery product of the selected design pattern cannot be produced normally. The technique of the present invention is to lower the needle bar so as to be able to check the position of the head portion generated by the single yarn from a long distance, and to easily check the color of the single yarn threaded up close.

Even when the driving state of the head lamp unit 64 is not confirmed in the state, it is possible to easily check the descent state of the needle bar 66 from a long distance, and easily check the color of the embroidered thread near. .

In the second example, a state in which the second needle bar 66 is lowered and stopped from the right side of the left head part 30 is stopped and at the same time the head lamp unit 64 is driven. It is possible to easily check the generating head portion 30 and easily check the embroidery thread generated in the near yarn.

Since the head machine 30 is simultaneously driven and controlled in the same axis, and the head machine 30 is driven and controlled in the same way, when the single yarn occurs in any one of the head units 30, the driving of the whole machine 10 is temporarily stopped. Is stopped. In addition, a single yarn may occur simultaneously in a plurality of heads 30, in which case the corresponding needle bar 66 of the single yarn generated head 30 is all lowered.

For example, when the embroidery thread of the seventh needle bar 66 is single threaded at the same time, the head part 30, the head head 30, and the head head 30, in the multi-head embroidery machine, are numbered 1 and 3 times. 5 and the head portion 30, respectively, the needle bar 66 is lowered and the headlamp portion 64 is driven to display a single yarn state.

That is, the present invention monitors the single yarn that is not supplied with the embroidery thread, and when the single yarn is detected, driving the headlamp unit 64 to the head portion 30 in which the single yarn is generated while the operation of the embroidery machine 10 is stopped. At the same time, since the needle bar 66 that is caused by the single yarn is lowered to the maximum, the color of the head 30 and the yarn that is single threaded by the single yarn is easily checked by using the falling state of the needle bar 66.

In addition, in order to improve the working environment, the lighting is brightened, and the related technology development and the enlargement of the multi-head embroidery machine, for example, when the 48 head parts 30 are integrally formed, the head lamp part 64 for warning of the occurrence of single yarn 64 It is difficult to check the driving state of the, and can check the single yarn generating head portion 30 using the OP panel means 80, but the working radius of the worker moving to the OP panel means 80 located at one end increases the working time It solves problems such as lengthening.
