More specifically, sequential operation control method for mechanical equipment that repeatedly performs the same operation and requires the same arbitrary speed change (prior technology). Conventionally, for example, when a large number of spinning machines, such as spinning machines, are installed, each machine is controlled one by one. In many cases, the spinning machine is dedicated to that particular count, and in such cases there is almost no need to replace the pulley.Also, in order to increase the efficiency of work labor, even if the spinning machine is not full, it is necessary to A method of sequential dotting has been used. Furthermore, in order to reduce thread breakage in spinning machines, etc., vari-pitch pulleys, inverters, etc. are currently used on each machine.

と共に糸切れを減少せしめることにある。The present invention is an operation control method for a mechanical device that repeatedly performs the same operation and requires the same arbitrary speed change, in which the commercial power supply is operated at a constant speed sequentially to an arbitrary position by the same number of electric speed change devices as the mechanical device or less. An object of the present invention is to provide a sequential operation control system that performs low-speed operation, high-speed operation, or increasing/decelerating operation, and switches to commercial power during constant-speed operation. Another object of the present invention is to improve the power factor and efficiency of a main motor of a mechanical device such as a spinning machine and to reduce yarn breakage.

返し行なう運転制御方式である。(Means for Solving the Problems) Taking a spinning machine as an example of the configuration of the present invention, the speed can be increased from an arbitrary speed at the beginning of yarn winding to the maximum rotation speed using the same number of inverters as the spinning machine or less. When the spinning machine reaches its maximum speed, it switches to commercial power and operates the spinning machine at a constant speed. After that, the inverter increases the speed of the next spinning machine, and so on. It is a control method.

Further, after switching to the commercial power source and reaching the maximum rotation speed, it is possible to switch from the commercial power source to the inverter at the deceleration start position and perform deceleration operation. Further, the speed increase operation range and deceleration operation range can be determined by inputting time or percentage.
