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 work pieces.
Points for use
- To maximize efficiency the attachment at the tip of the stopper should be formed according to the work pieces shape.
Target workpiece
- Shape: round connector
- Size: φ30 x 15mm
- Weight: 0.1kg or less
Design Specifications
Operating Conditions or Design Requirements
- Stopper pin stroke：15mm
- Cylinder stroke：50mm
- Outer dimensions：W74xD170xH175mm
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.
