Description

Description: TECHNICAL FIELD The present invention relates to a yarn breakage detection method in a double twisting machine having a large number of double twisting machines arranged in a line and equipped with a doffing robot common to the machines.

[Conventional technology]

In a conventional double-twisting machine of this type, as shown in FIG. 2, a large number of double-twisting machines 11 are arranged in a row in which the right row R and the left row L are back to back with each other. Heavy twisting device 20
Is formed. The double twisting device 20 is controlled by the central control panel 12, and can run on rails 13 and 14 provided in front of the machine stands in the right row R and the left row L.
5 and 16 are also controlled by the central control panel 12. Each double twisting machine is provided with a display means 17 such as a lamp that lights up when winding is stopped. The winding stop state in which the lamp 17 is lit may be when the package is full or when the package is stopped due to yarn breakage. On the other hand, the doffing robot 15 is traveling on the rails 13 and stops at the front of the stop machine with the lamp 17 lit,
Whether the package 18 is full or not, or the presence or absence of the remaining yarn of the yarn supply is detected by a photoelectric tube or the like, and when the lamp 17 is turned on when the yarn is not full and the yarn is broken, the doffing robot 15 runs again. , Drive to the next machine with lamp 17 lit. When the tube is full, take out the package of the machine base and replace it with an empty paper tube. As a result, the machine is restarted and the lamp 17 of the machine is turned off.

In such a conventional double twisting machine, the operator finds a machine stand where the lamp 17 of each double twisting machine lights up and stops, and determines that the machine is stopped due to thread breakage rather than full pipe. Since the yarn splicing was done, the operator must always watch the lighting status of the lamp 17 of each machine base,
Not only does it require a great deal of attention, but it may take a long time to find the thread breaker. Also, in order to reduce such operator's work, the doffing robot 15
Although it is considered to provide a yarn splicing device in the above, the frequency of yarn breakage is not so high due to the recent technical progress of the double twisting machine. On the other hand, the yarn splicing device is expensive, and adding it to each doffing robot 15 is not a good idea in terms of price.

[Problems to be Solved by the Invention]

The present invention has been made in view of the above points, and an object of the present invention is to make it possible to easily detect a yarn break of each double twisting machine.

[Means for Solving the Problems]

The present invention has a plurality of double-twisting machines arranged in a row, and is equipped with a doffing robot common to each machine, and each machine is provided with a doffing robot stop display device that operates when fully wound and when a thread is broken, and is run. The doffing robot that came, in the yarn breakage detection display method of the double twisting machine that stops on the machine on which the doffing robot stop display device is operating, travels to the machine on which the doffing robot displays stop, When it is detected that the machine is stopped and displayed in a state other than full winding, the display device of the central control panel of the row to which the machine belongs belongs indicates that there is a machine stopped due to thread breakage.

[Action]

Since the present invention is configured as described above, when the display device of each double twisting machine operates to display the stop of the machine base, the running robot stops at the machine base and stops due to full pipe. Whether or not it is full, the doffing work is performed, and when it is not fully filled, it stops on the central control panel of the row of each machine stand due to a thread break in the double twisting machine of that row. It indicates that the machine that is operating exists.

〔Example〕

 An embodiment of the present invention will be described with reference to FIG.

A large number of double twisting machines 1 are arranged in a row in which the right row R and the left row L are back-to-back with each other to form a single row double twisting apparatus 2. The double twisting device 2 is controlled by the central control panel 3, and the doffing robots 5 and 6 traveling on the rails 4 provided on the front faces of the machine stands of the right row R and the left row L are also controlled by the central control panel. Controlled. Each double twisting machine is provided with a lamp 7 that lights up when winding is stopped, and a lamp 8 is provided on the front surface of the central control panel 3 common to the respective machines. The double twisting machine in which the lamp 7 of each machine is lit is in a stopped state when the package is full or when the yarn is broken, but the doffing robots 5 and 6 travel on the rail 4 and the lamp 7 is lit. If the package 9 is full, the photoelectric tube detects whether or not the package 9 is full, or the presence or absence of residual yarn in the yarn supply. The robot 15 travels again and travels to the next machine with the lamp 7 lit. At this time, send a signal through the trolley wire 10 to the central control panel of the row of each machine stand that it is not a stop due to a full pipe, but a stop due to a thread break,
The signal turns on the lamp 8 of the central control panel. Further, at the time of stopping when the tube is full, the package is replaced with an empty paper tube. As a result, the lamp 7 of the machine stand, which has been stopped because it is full, is turned off and restarted.

Therefore, the operator, by monitoring the lamp 8 of the central control panel 3, knows that there is a stop machine stand due to thread breakage in that row, and enters the row with that lamp and stops due to thread breakage. Performs splicing work for the heavy twisting machine.

It should be noted that the lamp 8 indicates that there is no paper tube in the paper tube stocker.
May be displayed on the screen, and in this case, the operator
When lit, check the paper core stocker of that row, supply when there is no paper core, and at some time know that the lamp is lit due to the existence of the thread breaker machine, Perform piecing.

Although the lamp is used as the stop display device of the machine base, it goes without saying that various other display devices can be used.

〔The invention's effect〕

Since the present invention is configured as described above, the operator only needs to monitor whether or not a display device such as a lamp is operating on the central control panel to check whether or not a stop machine stand due to yarn breakage exists. Since the information can be known, the attention required for monitoring can be reduced, and the time required for the thread break stop machine base can be reduced. In addition, it is necessary to use a yarn splicing device for the doffing robot, and the equipment cost is reduced.
