Lifting trolley is just outputed from de-stacking station and is fed, while another charged trolley just drives into and, and after in place, is continued
De-stacking is controlled by microcontroller in the process, and de-stacking station corresponds to two lifting trolleys, and two trolleys work alternatively.
The walking detection switch 18, lifting detection switch 21, preventing damage detection switch 28, synchronous detection switch 29 and
Photoelectric detection switch is connect with controller by conducting wire, and controller is microcontroller, and controller passes through conducting wire and first motor
16 and second motor 22 connect, walking detection switch 18, lifting detection switch 21, preventing damage detection switch 28, synchronous detection are opened
The signal of detection is passed to controller by pass 29 and photoelectric detection switch, and controller controls the positive and negative rotation of first motor 16 to control
The walking of trolley and controller control the positive and negative rotation of the second motor 22 to control the lifting of table top.
