 Width Change Mechanism

Right and left movement synchronization using center of the workpiece as the reference

1. Purpose
+ The sensor position is set up based on the size of the workpiece. (confirmation of the transferred workpiece width)
+ Confirm the size of the workpiece based on values on the scale plate. (Example: Applicable to workpiece A when the scale is 10mm)
+ Width of workpiece is changed equal from both sides (left and right) using center of the workpiece as the reference.
+ The backlash is reduced using tensile springs.

2. Points for use
+ A handle is used for adjustment, and rotation is stopped using a shaft collar.
+ A retro-reflective type is used for the sensor.

3. Target workpiece
+ Plastic BOX
+ Outer shape of large workpiece: W220xD150xH120mm
+ Outer shape of small workpiece: W50xD150xH120mm

4. Design Specifications
+ Operating Conditions or Design Requirements:
 External Dimensions: W440xD350xH219mm
 One side preparation stroke: 85mm
+ Selection Criteria for Main Components:
 Shaft collar
  > Selected as "fixed" after an adjustment.
 Handle
  > A handle which allows easy adjustment is selected.
 Tensile Springs
  > Selected to reduce backlash.
 Rack Gear
  > Two sections are selected to achieve synchronization.

I would like to hear what you think...suggestions and comments are welcome!
Thank you!
