The supply mechanism escapement separates supply parts to make subsequent operations (transfer, for example) easier to carry out by automating them.For this reason, almost every automation device in the workstation where the parts go through after escapement is designed with a sensor to detect parts.

• [Photo 1] is an image of how the positioning stage at the end of the chute looks after separating only one color ball by the rotary separation mechanism.
• The hand unit moves to pick up the ball after the photoelectric sensor has detected it the ball stage.
• Another photoelectric sensor is also installed directly below the table where color balls are arranged for the bingo game. This sensor detects a ball and determines whether or not to move the hand unit to a designated location. ([Photo 2])
• The photoelectric sensor needs to be mounted so that the stage can position parts detected at an appropriate location (angle, height, and distance). To make this operation possible, a slotted-hole shape for the mounting hole on the L-shaped sheet metal is adopted. The L-shaped sheet metal can be separated into two parts, if necessary, in order to adjust the height.
