Cautions on the CAD data
-
Assembly data shows the assembly drawings in the concept design phase. The sole purpose of the data is to explain the structure and functionality of the assembly and is not considered nor to be used as a final design.
You will need to edit the Data so that it meets your specific design conditions. -
The CAD data unit assembly consists of sub-assemblies.
Each sub-assembly unit can be used as it is or can be edited. - The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
- The Data including the third-part components are made by the Company.
* The part in the frame is a sub-assembly unit.

Application Overview
Purpose
- Purpose
- Separates workpieces on the feeder.
- Operation
- As a single cylinder operates two sets of plate cams simultaneously, two sets of stoppers alternatively move up and down to separate workpieces.
Points for use
- To maximize efficiency the attachment at the tip of the stopper should be formed according to the workpieces shape.
Target workpiece
- Shape: round connector
- Size: Ø30 x 15mm
- Weight: 0.1kg or less
Design Specifications
Operating Conditions or Design Requirements
- Stopper pin stroke: 15mm
- Cylinder stroke: 50mm
- Outer dimensions: W74 x D170 x H175mm
Selection Criteria for Main Components
- A compression spring with a loose length of 25mm or longer and a compressed length less than 10mm is selected.
Design Evaluation
Verification of main components
- Selection of a compression spring
- Conditional value: free length of compression spring L1 = 30mm, solid length of compression spring L2=5.6mm
The length (free length) L3 of the spring required in this mechanism is L3 > 25mm
And its solid length is L4 < 10mm
Therefore,
The selected compression spring satisfies L1 > L3 and L2 < L4
Other Design Consideration
- This mechanism can be manufactured with a set of plate cams and a stopper unit.
- Depending on the mutual design of the two plate cams, it is possible to change the escape timing.
