The starting of the variable frequency speed control system is mostly started from low speed, and the frequency is low. The acceleration and deceleration time can be set at will, so the acceleration and deceleration time is relatively gentle, the starting current is relatively small, and the start and stop with relatively high frequency can be carried out; a limit switch is an automatic control appliance that converts a machine signal into an electrical signal to control the position or travel of a moving part. The clamp module, i.e., the clamp mechanism 212, has a cylinder 2120 as a main component; the protection module is mainly used for power-off protection when the cylinder 2120 fails. Under the control condition of the frequency converter control module, the air cylinder 2120 executes the action requirement of the relevant position of the electromagnetic valve, provides power at a certain speed within a certain time to clamp goods, judges the actual condition of the executing mechanism in the protection module, and stops executing overturning or lifting when a fault occurs.

Specifically, as shown in fig. 4, an operation principle of an overturning fixture device 100 provided in an embodiment of the present application is schematically illustrated, and the operation process of the main components will be described below.

The operation knob K2 is rotated forward and turned over, the HL2 turning indicator light is on, the rotary fixing frame 210 starts to turn over, and the rotary fixing frame is automatically stopped after rotating 180 degrees. K8 is a photoelectric sensor provided in the turning jig device 100, and when a person approaches the turning jig device 100, the photoelectric sensor K8 is turned off, and the turning jig device 100 stops turning. When the lifting and descending movement is performed, the limit switches KM3 and KM4 are operated, the turnover fixture device 100 is lifted or descended, and the lifting indicator lamp is turned on. It should be noted that, during the operation, if the power supply can not be started, it should be checked whether the air pressure reaches 0.6 Mp.

The limit switch consists of an operating head, a contact system and a shell, and is an automatic control electric appliance for converting machine signals into electric signals so as to control the position or the stroke of a moving part. The working principle is that the contact of the mechanical moving part is operated to realize connection or disconnection by utilizing the collision of the mechanical moving part, thereby achieving a certain control purpose.
