Textile machinery systems, control methods, and programs

Abstract

The lifting mechanism determines whether or not the package has been separated from the drum. [Solution] The textile machinery system 100 manages a manufacturing apparatus 1 that winds yarn 14 to produce a package 22. The manufacturing apparatus 1 includes a cradle 18 that supports the package 22, a lifting mechanism 50 that raises and lowers the cradle 18, and a winding drum 20 that rotates in contact with the package 22. The textile machinery system 100 includes a control unit F1 that, in the event of yarn breakage, raises the cradle 18 using the lifting mechanism 50 to separate the package 22 from the winding drum 20 and brakes the winding drum 20 which is rotated by a drum drive motor 21, and a determination unit F3 that determines whether there is an abnormality in the lifting mechanism 50 based on the stopping time from the start of braking of the winding drum 20 until the rotation stops.

Claims

1. A textile machinery system that manages a manufacturing device that winds yarn and produces packaging, The aforementioned manufacturing apparatus, A support portion that supports the package, A lifting mechanism for raising and lowering the support portion, A drum that rotates while in frictional contact with the surface of the package, It has, When the thread breaks, the lifting mechanism raises the support portion to separate the surface of the package from the surface of the drum, and the control unit brakes the package or the drum which is rotated by a driving force provided by the drive device, A determination unit that determines whether or not there is an abnormality in the lifting mechanism based on the stopping time from when braking begins on the package or drum, which is rotated by the drive device, until the rotation stops, A textile machinery system equipped with the following features.

2. The textile machine system according to claim 1, wherein the determination unit determines whether or not there is an abnormality in the lifting mechanism based on the ratio of the maximum value of the stopping time and the average value of the rotational speed of the package or drum when the braking is initiated.

3. The textile machinery system according to claim 1 or 2, wherein the determination unit determines whether or not there is an abnormality in the lifting mechanism based on the ratio of the standard deviation of the stopping time to the average value of the stopping time.

4. The control unit controls the package or drum, which is rotated by the drive device, to accelerate from a stopped state to a predetermined constant rotational speed. The textile machinery system according to any one of claims 1 to 3, wherein the stopping time is the time it takes for the rotational speed of the package or drum, which is driven by the drive device, to drop from the constant rotational speed to zero.

5. The textile machinery system according to claim 4, wherein the stopping time obtained when braking is initiated while the package or drum, which is rotated by the drive device, is accelerating and before it reaches the constant rotational speed, is not used to determine whether or not there is an abnormality in the lifting mechanism.

6. The textile machinery system according to any one of claims 1 to 5, wherein whether or not there is an abnormality in the lifting mechanism is determined based on the stopping time from when the braking of the package or drum, which is rotated by the drive device when the package is fully wound, begins until the rotation stops.

7. The textile machinery system according to any one of claims 1 to 6, further comprising a notification unit that notifies of an abnormality in the lifting mechanism when it is determined that there is an abnormality in the lifting mechanism.

8. The textile machinery system according to any one of claims 1 to 7, wherein the lifting mechanism includes an air cylinder.

9. A management method for managing a manufacturing apparatus that winds thread to produce packaging, The aforementioned manufacturing apparatus, A support portion that supports the package, A lifting mechanism for raising and lowering the support portion, A drum that rotates while in frictional contact with the surface of the package, It has, In the event of thread breakage, the lifting mechanism raises the support portion to separate the surface of the package from the surface of the drum, and the drive device applies a driving force to the rotating package or drum to brake it. A step of determining whether there is an abnormality in the lifting mechanism based on the stopping time from when braking begins on the package or drum, which is rotated by the drive device, until the rotation stops. A management method that includes the following features.

10. A program that causes a computer to execute the management method described in claim 9.
