The present invention relates to a method for controlling an individual yarn and a device for automatically cutting the length of the thread wound on the bobbin to cut at full winding. Conventionally, in order to control the length of the thread wound on the bobbin, a combination of a bottom switch or a proximity switch generates a signal corresponding to the length of the thread being wound and displays it by an electronic or mechanical counter. As it was controlled to be wound by a certain length, a separate workforce was required for winding work, which caused a separate burden of labor costs, and a considerable error occurred depending on the individual ability of the worker, producing a product of the same specification. It became hard to do.

In addition, according to this conventional method, there is a problem in that it is not possible to control the president to be wound by four kinds or weights by winding the president of the whole weight by one counter.

To solve these problems, the present invention controls the exact length of the wound yarn by measuring the length of the wound yarn and measuring the circumference of the drum. When the set value is reached, the thread is cut and the winding is stopped to enable automatic operation that minimizes the use of manpower, thereby reducing labor costs and increasing production volume. The purpose is to facilitate the selection of the president according to the winding.

The object of the present invention is to provide an encoder for adjusting the length of the thread wound for the dead-length control, a proximity sensor for measuring the circumference of the drum is connected to the input port of the microcomputer, a solenoid for lifting the wound bobbin and This can be achieved by connecting the solenoid for cutting the air cylinder, the electromagnetic brake, and the seal to the output port of the microcomputer, which will be described in detail with reference to the accompanying drawings.

An encoder (1) for measuring the length of the yarn moving to the bobbin, a proximity sensor (2) installed on the side of the bobbin to detect the change in the diameter of the bobbin, a set-up president and present president consisting of an LED or LCD, and To an indicator 3 for displaying various operating states, a keypad 4 for controlling various data and operations such as a setting site, an electromagnetic brake 5 for stopping winding operation at full winding, and a bobbin at full winding Cutting solenoid 6 for cutting the supplied thread, and air cylinder 7 and solenoid 8 for stopping the winding operation by lifting the bobbin at full winding. The accumulation force of 9) is made by connecting to the port.

According to the present invention, the power supply is started by pressing a key corresponding to the ON of the keypad 4 of the device, and then pressing a specific key (for example, EDIT) of the keypad 4, and then depending on the system, a numeric key or a numeric increase or decrease key. Press to enter the default value.

After the input of the deadweight data is completed, the rotation is detected by the encoder 1 or the proximity processor 2 according to the operation method of the machine to detect whether the thread is wound on the bobbin. When the winding signal of the thread caused by the order (2) is generated, the current dead-weight value is increased. If the current dead-weight value is not equal to the set dead-weight value, it is determined whether the yarn is wound on the bobbin described above. It is detected by the encoder (1) or the proximity sequencer (2), and the process of recognizing whether or not the full range by comparing the current and still value and the set value by the winding signal.

In this way, when the current presidential value and the set presidential value are the same volume, the microcomputer 9 turns on the indicator lamp of the indicator 3 indicating the full volume through the output port, and the electromagnetic brake 5 To stop the rotation of the bobbin and at the same time operate the cutting solenoid (6) to cut the thread, and to operate the air cylinder (7) and the solenoid (8) for lifting the bobbin, winding the thread of a certain bed You can get a bobbin.

Subsequently, it is checked whether there is a key input corresponding to the reset of the keypad 4, and if there is a key input corresponding to the reset by the user's key operation, the setting dead value is cleared and the key input is again performed. By repeating the above-described process of pressing a specific key (e.g. EDIT) on the keypad 4 and pressing a numeric key or a numeric increase / decrease key according to the system to input the set president value, the thread can be continuously wound into the desired president. It will be possible.

In this case, the winding may be cut off due to various factors. In this case, the signal supplied from the proximity sensor or the encoder is interrupted. In this case, see if the signal is not input continuously for more than 1 second. (9) turns on the trimming lamp of the indicator 3 so that an operator may take appropriate measures.

In this way, the present invention can obtain a bobbin in which the thread of the desired president is wound by each weight only by repeatedly turning on the system and then inputting the setting president value and pressing the reset key.

In this way, the continuous automatic winding is possible, which leads to a drastic reduction in labor cost, mass production, and an electric cylinder (7) and solenoid (8) for lifting the electromagnetic brake (5) and cutting solenoids and bobbins. It is possible to obtain a bobbin wound the thread of the correct length by the product to be able to produce a product of uniform quality, and because it can be wound by varying the set boss for each weight depending on the type of plant, the useful effect have.

Claims (2)

After pressing a specific key (e.g. EDIT) on the keypad (4), press the numeric key or the numeric increase / decrease key according to the system to input the set dead value, and then detect the rotation by the encoder (1) or the proximity sensor (2) to the bobbin. It is to detect whether the thread is wound, and to detect the winding signal of the thread by the encoder (1) or the proximity sequencer (2) to increase the current dead value. If the comparison is not the same, the process of increasing the current value of the dead stock and the value of the current dead stock is repeated by repeating the process of detecting the bobbin as described above.
