Application Overview
Purpose
- The opening/closing action of an arm, stopper, etc., is driven by gears.
Target workpiece
- Shape: stepped resin (PVC) part
- Size: D100 x H90mm
- Weight: 0.4kg
Design Specifications
Operating Conditions or Design Requirements
- Opening/closing arm oscillation angle: 25°
- Arm open (close) operation time: 0.2sec
- Operating pressure: 0.3Mpa
- Cylinder stroke: 50mm
- Piston speed: 250mm/sec
- Conveyor speed: 100mm/sec
- Distance workpiece moves in arm operation time: L = 100 x 0.2/1 = 20mm
- Outer dimensions: W247 x D410 x H279mm
Required Performance
- Load: 164N or less (30 workpieces)
Selection Criteria for Main Components
- To satisfy the required load, a φ32 cylinder is selected.
Design Evaluation
Verification of main components
- The cylinder thrust load and the strength of the arm are verified.
- Selection of cylinder
Workpiece mass: m = 0.4kg
Number of workpieces: N = 30pieces
Friction coefficient between workpiece and conveyor: μ = 0.7
Total workpiece weight: M = 0.5 x 30 = 12kg
Load applied by workpiece: F1 = μ x M x 9.8 = 0.7 x 12 x 9.8 = 82N
If we use 2 as the safety factor, F2 = 2 x F1 = 164N
From cylinder thrust P = 207N,
F2 < P - Confirmation of strength of arm that receives workpiece load.
Arm width: b = 40mm
Arm plate thickness: t = 4.5mm
Arm length: L = 115mm
Bending stress applied to arm: σ1 = 6 x F1 x L/bt2 = 6 x 82 x 115/40 x (4.5)2 = 70N/mm²
Allowable bending stress of 1018 Carbon Steel: σ = 157N/mm²
Therefore, σ1 < σ
Other Design Consideration
- Space can be saved by installing the cylinder below the transfer surface.
- The cover of the whole conveyor including the peripheral devices also serves as a safety cover for the drive section.
