Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operation control of a spinning machine such as a spinning machine and a twisting machine.

[0002]

2. Description of the Related Art In this type of spinning machine, the operating conditions of the machine base are determined on the basis of the product type, and the gear ratio of each device, such as the spindle rotation speed, the ring rail lifting speed, the ring rail shaper feed amount, etc. The operating conditions could be changed by setting. For this reason, it takes a lot of time to adjust the gear ratio, etc., so that each device is equipped with a control motor, and each control motor is controlled by an electric command to change the operating conditions. Japanese Patent Application Laid-Open No. 3-64529 discloses that the operator sets data of operating conditions suitable for the above.

[0003]

According to the above-mentioned conventional apparatus, it is not necessary to adjust the gear ratio of each device such as the spindle rotation speed, the ring rail lifting speed, the shaper feed amount, etc. However, when the operating conditions are changed due to the change of the in-process type, the worker must reset the data one by one in the control device each time. Since it takes a lot of time and a lot of time, it is desired to improve the work efficiency. Therefore, it is an object of the present invention to obtain an operation control device for a spinning machine, which allows easy setting of data in each device when operating conditions are changed.

Is characterized by.

[0005]

According to the present invention, prior to the operation, a data group combining the respective data of the spindle rotational speed, the ring rail lifting speed and the shaper feed amount, which are the optimum operating conditions for the in-process product, is distinguished for each in-process product, and The plurality of data groups are stored in the storage means by the input means. Therefore, when the operating condition is newly set by changing the device type, a data group most suitable for the device type is selected from the stored data group by the selecting means. The output means outputs a drive command to each drive motor based on the data of the selected data group to control the drive. Even if the device type is changed in this way, the optimum operation can be easily set only by selecting one data group from the data group by the selecting means at the time of resetting.

1 is a spindle of a spinning machine, which is rotated from a main motor M1 via a chin pulley shaft 3 and the like. The main motor M1 drives the front roller 5, the middle roller 6, and the back roller 7 of the draft part 4 so as to have a predetermined draft ratio.
Further, the front roller 5 is provided with a spinning amount detector 54 for detecting the spinning amount. The ring rail 10 is connected to the lifting pillar 11, and the lower end of the lifting pillar 11 is connected to one end of the lifting tape 12. The other end of the lifting tape 12 is connected to a lifting roller 14 integrally attached to the ring rail lifting shaft 13. Another roller 15 is integrally attached to the ring rail elevating shaft 13, and the other end of the lifting tape 16 having one end fixed to the roller 15 is rotatably guided in the middle of the lifting lever 17 to a guide roller 18.
It is fixed to the lifting drum 19 via. The lifting drum 19 is rotated by a shaper feed motor M3 via a gear pair 28 and a clutch 27, and the rotation of the lifting drum 19 can be detected by a rotation amount detection encoder 29 connected to the gear pair 28. The clutch 27 is engaged during the forming of the yarn, and is disengaged when the ring rail 10 is lowered after the pipe is full.

The lifting lever 17 is swingably supported around a pivot 20, and the tip of the lifting lever 17 is in pressure contact with the heart cam 21. Heart cam 21
Is connected to a ring rail raising / lowering motor M2 for raising and lowering the ring rail 10 via a gear pair 25. A variable speed motor is used as the ring rail lifting motor M2, and one cycle of vertical movement (chase) is given to the ring rail 10 via the guide roller 18 by swinging of the lifting lever 17 while the heart cam 21 makes one rotation. To be In addition, the shaper feed motor M3 rotates for each chase of raising and lowering the ring rail, and this rotation causes the clutch 27 to rotate.
The lifting drum 19 is rotated in the tape winding direction via the gear pair 28 and the gear pair 28.
The shaper feed that gradually rises is given. A clutch 62 is interposed in the drive system between the gear pair 28 and the pulley 22. The clutch 62 is engaged only when the clutch 27 is disengaged, that is, when the ring is full, and the ring rail 10 is lowered. .
