Application Overview
Purpose
- Purpose
- Workpiece is lowered and transferred to another line during the conveying process.
- Operation
- In the middle of the conveyor a set of links and a cylinder are used to lower and tilt the platform. This allows the workpiece to slide and transfer over to another conveying line.
Points for use
- Workpiece is either ejected or transferred.
Target workpiece
- Shape: Medium type packing/pallet
- Size: W 180 x D 180 x H50mm
- Weight: 1kg
Design Specifications
Operating Conditions or Design Requirements
- Up/down stroke: 20mm
- Shoot angle: 10°
- External dimensions: W 1020 x D 450 x H 525mm
Required Performance
- Workpiece load: 10N
Selection Criteria for Main Components
- Cylinder.
- Up/down is Down when pressure is reduced.
- Link ration
3：2 - Mechanism weight
Approx. 7kg
Design Evaluation
Verification of main components
- Cylinder thrust is verified to check if table driving is possible.
- Checking work support weight P at table lifting.
- Condition value: Workpiece m = 1kg, gravity acceleration g = 9.8m/s², cylinder diameter = 20mm, supplied pressure = 0.5MPa, link ratio = cylinder side arm: table side arm = 3:2, cylinder thrust = 157N, angle between link and cylinder at table lifting θ= 22°, mechanical efficiency = 50%, mass of equipment around table ≒ 7kg (≒ 68.6N)
- Sustaining force of cylinder F = thrust x cosθ x link ratio x mechanical efficiency, thus F = 157 x cos22° x (3/2) x 0.5 = 109.1N
- Table sustaining force: P = F - mass of equipment around table, thus P = 109.1 - 68.6 = 40.5N
-> 40.5N, safety margin 4.13 (= 40.5/9.8) for a workpiece with weight of 1 kg ( 9.8N), which enables table driving
Other Design Consideration
- A Clevis type is adopted in order to minimize the operation angle of the link arm and cylinder.
- Deviation of the direction of work transfer from the direction of shoot is permitted by using a ball roller.
- The level of lift, vertical stroke and shoot angle are adjusted by the set-collar and knuckle position.
- The level of lift, stroke of up/down and shoot angle are adjusted by the set-collar and knuckle position.
