Problems solved by technology

However, when the braking operation is performed in such a way that the rotation of the main shaft is stopped for a relatively long stop time, the electromagnetic brake performs braking for a long time every time the braking operation is performed. Also, there may be problems such as early wear of the brake parts in the electromagnetic brake

Embodiment Construction

[0041] Hereinafter, an embodiment of the present invention will be described based on FIG. 1 and FIG. 2 .

[0044] In addition, the control device 30 includes a main control unit 32 to which the above-mentioned input setting device 40 is connected, and a main control unit 32 connected to the main control unit.

[0045] In addition, the control device 30 further includes an inverter 36 that controls the driving of the drive motor 20 described above. Moreover, the inverter

[0046] In addition, the loom has an angle detector 50 that detects the rotation angle of the main shaft 10, and the angle detector 50 is configured to:

[0052] Furthermore, the amount of decrease in the command rotational speed (the amount of decrease in rotational speed) for each change is determined as the regeneration accompanying the change.

[0055] However, when the regenerative braking is performed according to the change of the command rotational speed, the regenerative electric power is generated as de...

Abstract

The invention discloses a method for stopping a loom and a loom for realizing the method. The loom includes a control device for controlling the rotation of the main shaft based on a predetermined commanded rotational speed and an electromagnetic brake for applying braking to the main shaft. During operation, the control device controls the rotation of the main shaft based on a preset stable rotational speed, and the stopping method of the loom includes: the first braking process, which starts after the time when the stop command is issued, and changes the commanded rotational speed more than twice Decreasing the rotational speed of the main shaft toward a predetermined stop rotational speed lower than the stable rotational speed; and a second braking process of activating the electromagnetic brake after reaching the stop rotational speed to brake the main shaft and stop the rotation of the main shaft. According to the present invention, in a loom that performs a braking operation by combining regenerative braking and electromagnetic brake braking, it is possible to reduce the load applied to mechanical components and the like without causing damage caused by regenerative braking. question.

Description

Stopping method of loom and loom for realizing the stopping method technical field The present invention relates to a loom comprising a controller that controls the rotation of the main shaft based on a predetermined commanded rotational speed. The control device and the electromagnetic brake that applies the brake to the main shaft, during stable operation, the control device is based on the preset stable rotation speed. Speed ​​controls the rotation of the spindle. Background technique When the loom is running stably, its operation is carried out by controlling the driving of the prime mover motor, so that the main shaft is pre-set The stable speed is driven to rotate. In addition, the loom is provided with a control device, and the driving of the drive motor is predetermined by the control device. the commanded speed. In addition, the control device is configured to include, for example, an inverter, and by setting the output frequency of the inverter to The f...
