Making conveyor angle variable with a cylinder download with free cad models



A conveyor that delivers two different type of workpieces into their respective container.The cylinder, rotary shaft base and pin support are connected and placed on an external frame.

Target workpiece
Plastic molded goods
Dimensions: SR: 40 mm x H: 32 mm
Mass: 0.16kg
Design Specifications
Operating Conditions or Design Requirements
Drive part dimensions
Height of bottom portion - conveyor at horizontal (maximum) position: 1242 mm
Conveyor length: 900 mm, belt width: 200 mm
Frame width: 330 mm
Operation specifications
Cylinder stroke: 200 mm
Difference of elevation at conveyor exit: 223.3 mm

Design Evaluation
Verification of main components
Verify cylinder thrust for conveyor frame weight.
Cylinder capacity:
Conditional values: Distance between cylinder side hinge and rotary shaft: r1 = 715.5 mm, Distance between frame center and rotary shaft: r2 = 325 mm, conveyor frame part mass m = 40.0 kg
Thrust required for drive under moment around rotary shaft: F1 = F2 x r2/r1 Thus, F1 = 40 x 9.8 x 325/715.5 = 178N
Operating air pressure: 0.5 MPa, cylinder I.D. 63 mm, outstroke cylinder output at load factor of 0.5 F0 = 770 N (SMC catalogue value)
Safety factor: Sf = F0/F1 = 770/178 = 4.32

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