    This data is utilized in order to list more useful application examples in the future.

    Cautions on the CAD data

    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. The CAD data unit assembly consists of sub-assemblies.
      Each sub-assembly unit can be used as it is or can be 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 dimensions of the MISUMI parts in the Data, which can be specifed at 1mm intervals, can be edited under historical data.
    6. The Data including the third-part components are made by the Company.

Application Overview

Purpose

  • Tension control by utilizing a dancer mechanism in the sheet feed.

Points for use

  • Used in sheet roll feeding applications.

Target workpiece

  • Shape: sheet
    Size: W10 x t0.2mm

Design Specifications

Operating Conditions or Design Requirements

  • Dancer stroke = 100mm
  • Tension = 2N

Required Performance

  • Total load of dancer roll and weight: M = 2 to 4N

Selection Criteria for Main Components

  • With conditions of sheet roll maximum diameter: D = 105mm and maximum tension generated by motor: F = M/2 = 2N, the motor is selected.

Design Evaluation

Verification of main components

  • Verification of sufficiency of torque.
    • From required motor torque: T = D/2 x F, T = 0.0525 x 2 = 0.1N・m
      0.1 x 2 (safety factor) = 0.2N・m < 0.29N・m = motor torque
      -> There is no problem.

Other Design Considerations

  • The dancer mechanism part is compact and fits in a space equivalent to the sheet roll diameter.
    When the position of the dancer roll is detected by the sensors, the workpiece feed is turned off and when its up its turned on.
