    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.

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

Application Overview

Purpose

  • Feeding sheet-like workpieces such as films using rollers.

Target workpiece

  • Shape: Film, sheet
  • Size: W20×t0.1mm

Design Specifications

Operating Conditions or Design Requirements

  • External dimensions: W209xD110xH168mm
  • Feeding speed: 300mm/s

Required Performance

  • Tension: 4N
  • Nip pressure

    Nip means the contact surfaces of circles. Nip pressure means the contact pressure between the rollers.

    ：10N

Selection Criteria for Main Components

  • Select a 50 W motor to feed workpieces at a tension of 4N,a nip pressure of 10N, and a seep of 300mm/s.

Design Evaluation

Verification of main components

  • Select a motor that satisfies the load inertia and load torque.
  • Calculation of the load inertia applied to the motor shaft.
    • Conditions (values): Feeding shaft inertia JO=0.028kg･cm2, coupling inertia JC=0.028kg･cm2, feeding roller inertia JR=0.170kg･cm2
    • The load inertia applied to the motor shaft, JL, is expressed by JL=JC+JO+2×JR (JL=0.028+0.028+2×0.170 =0.396kg･cm2)
    • The inertia ratio, m, is expressed by m=JL/JM (m=0.396/0.045=8.8<17 times (motor specification recommendation value))
  • Calculation of torque in acceleration.
    • Conditions (values): Drive efficiency η=0.800, motor rotation speed N0=190.985r/min,acceleration time Tsa=0.500s,the load torque applied to the motor shaft TL=0.097N・m
    • Torque in acceleration, TMa, is expressed by TMa=((((JL/η)+JM)×N0)/(9.55×104×Tsa))+TL. (TMa=((((0.396/0.800)+0.045)×190.985)/(9.55×104×0.5))+0.097=0.099N・m)
    • The torque reaches its peak in acceleration. Since the rated torque is Ttyp=0.160N・m, the peak load factor Rp is
      expressed by Rp=(TMa/Ttyp)×100 (Rp=(0.099/0.16)×100=61.875%)
    • When the effective load torque is derived from the torques of each operation pattern,
      the rated torque becomes 0.096N・m<0.16N・m

Other Design Consideration

  • Knurling is applied to the feeding rollers while urethane bumpers are applied to the press roller to increase the friction coefficient.
  • The Nip pressure

    Nip means the contact surfaces of circles. Nip pressure means the contact pressure between the rollers.

    can be adjusted by changing the springs.
