IDEA NOTE Multiple smaller motors can be used to support the required weight.

As two motors share the weight of the conveyed object, it is possible to use smaller motors, limit the height of the device, and make the device structure suitable for installation between conveyors.

IDEA NOTE Conveyance of driving power via friction force

In order to convey driving power to the engineered plastic bearings that are usually used simply as roller guides, the friction force generated between the engineered plastic bearing and the pulley is used to directly drive the engineered plastic bearings.

    CAD Data Limitations

    1. 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.
    2. Unit assembly Data consists of some sub-assemblies.
      It is configured so that each sub-assembly unit can be used as it is or edited.
    3. * The part in the frame is a sub-assembly unit.

    4. The Data for fabricated parts is based on easy-to-edit dimensions and shapes in sketches and histories.
    5. The Data including the third-part components are made by the Company.

  • * Unit assembly Data consists of some sub-assemblies.
       It is configured so that each sub-assembly unit can be used as it is or edited.

Application Overview

Purpose

  • Purpose
    • Branches pallets being conveyed on the storage conveyor at a right angle. Or merges the pallet flowing from another conveyor at a right angle.
      It is possible to branch and merge on both sides of the storage conveyor feed direction.
  • Operation
    • 1. Branching: When a pallet arrives at the branching position, the drive roller mechanism ascends to lift the pallet from the conveyor, conveying the pallet to another conveyor. Then, the drive roller mechanism descends.

      2. Merging: When the pallet arrives at the merging position from another conveyor, the drive roller mechanism ascends and the drive roller operated to receive the pallet to be conveyed by the storage conveyor. The Drive roller mechanism descends to merge the pallet into storage conveyor flow.

Points for use

  • Used in conveyance line in plant

Target workpiece

  • Shape: pallet
  • Size: W550xD450xH20mm
  • Weight: pallet750N
    Weight of conveyed material: 100N

Design Specifications

Operating Conditions or Design Requirements

  • Branching/merging distance: 650mm
  • Lift stroke: 50mm
  • Outer dimensions: W510 x D230 x H314mm

Required Performance

  • Positioning accuracy:±5mm
    Weight of conveyed object: 100N

Selection Criteria for Main Components

  • To lift drive roller body (240N) + conveyed object (100N) + pallet (75N) = 415 (N), selected φ63 air cylinder.
    To convey at a speed of 15m/min, selected a gear head with a gear ratio of 1/20.

Design Evaluation

Verification of main components

  • Whether the cylinder thrust, motor capacity, etc., are appropriate based on the load is verified.
  • Lift unit:
    • Conditional value: conveyor lift unit weight 240N, conveyed object weight 100N, pallet weight 75N, total weight 415N, and friction coefficient 0.2
    • Theoretical output of lift power of cylinder with lift guide when air pressure is 0.4MPa: 1250 × 0.7 (mechanical efficiency) = 875N ⇒ as it is 47% of lift output (= 415/875 × 100), this is acceptable.
  • Drive roller travel unit:
    • Conveyed object 100N + pallet 75N, total 175N/2 (2 motors) = 87.5N, speed = 15m/min, mechanical efficiency = 0.7
    • Capacity calculation: N = conveyed object [kg] × friction coefficient × speed [m/min]/(6120 × mechanical efficiency) 
      Therefore, N = (87.5/9.8) × 0.2 × 15/(6120 × 0.7) = 0.0061kW
      ⇒ as motor in use has a capacity of 60W, this is acceptable.
  • Selection of roller chain:
    • Motor 60W, number of sprocket teeth 11T, number of sprocket rotations 75rpm, design power 60W × 1.3 (use factor) = compensated conveyance power 78W
      ⇒ As 0.37kW > 78 W from the CHEM40 electric power table, there is no problem.

Other Design Consideration

  • Air cylinder is used to simplify the vertical lift mechanism.
  • Drives pallet by friction force generated between the drive pulley and the engineered plastic bearing.
  • Two motors are operated in parallel, and speed synchronization between them is enabled through an external speed control, or by a DC voltage control.
