Operation control method of vibrating screen machine

Abstract

In order to provide the operation control method of the vibrating machine that can reliably reduce the capacity of the required motor and power consumption, the threshold value based on the magnitude of the load is preset, and the rotational drive state of the two rotating shafts (31a, 31b) transitions to After the steady state, when the magnitude of the load is smaller than the threshold value, the transmission of the rotational driving force to one of the two rotational shafts (31a, 31b) is stopped, and the vibration generated by the rotational drive of the other rotational shaft is utilized. The rotating shaft whose transmission of the rotating driving force is stopped is driven to rotate in conjunction with the other rotating shaft, and when the magnitude of the load is larger than a threshold value, the rotating shaft whose transmission of the rotating driving force is stopped is started to be transmitted, and the Two rotating shafts (31a, 31b) are driven in rotation.

Description

technical field [0001] The present invention relates to an operation control method of a vibrating screen machine, in particular to an operation control method of a vibrating screen machine provided with a vibration generating device which is provided with two rotating shafts equipped with eccentric weights in parallel and uses An electric motor is provided to independently rotate and drive the two rotating shafts. Background technique [0002] In the past, as a screen shaker, a screen shaker provided with a vibration generating device has been widely used. The vibration generating device generates vibration by rotating two rotating shafts equipped with eccentric weights arranged in parallel in opposite directions (for example, refer to Patent Literature 1). [0003] In addition, in this vibration generating device, as a method of rotating the two rotating shafts in opposite directions, the two rotating shafts are connected using gears, so that the rotational driving force ...

Problems solved by technology

[0007] (2) Therefore, during operation, the load factor relative to the capacity of the motor may be lower than that of the vibration generating device using gears, which may cause power loss from the viewpoint of the characteristics of the motor (low efficiency in the use state with a low load factor). increased consumption

In this case, since a large amount of space for the motor is used, it is generally possible to save space by integrating the motor and the vibrating machine, and the motor and the vibrating machine vibrate together, but the weight of the vibrating machine increases, and eventually lead to an increase in power
