Workpiece reversal transfer mechanism
■ Mechanism function
Rotates the workpiece on the conveyor belt by 90 degrees and transfers it to the next process.
At this time, the clamping mechanism rotates 180 degrees and does not change the direction of the workpiece relative to the conveying direction at the same time during transfer.
■Role of the Timing Pulley
The transmission of the timing pulley and the timing belt changes the placement direction of the workpiece while transferring the workpiece. (Applicable to S specification and GT specification timing pulleys)
