IDEA NOTE Prevent failure when closing or affixing maintenance door

As the dog for the open and close check is flipped by the spring, it is not possible to shield the sensor from light unless the door is fixed.

    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.

Application Overview

Purpose

  • Purpose
    • Prevents failure when closing or affixing the maintenance door.
  • Operation
    • After closing the door, fix the bracket connected to the door with the spring hinge using the knurled knob. At this point, the bracket shields the sensor from light. By removing the knurled knob, the bracket and knob are flipped up, tripping the check sensor.

Points for use

  • Manually operated.

Target workpiece

  • Doors that require interlock

    A mechanism, used as a safety mechanism, that disables other operations when predetermined conditions are not satisfied.

    .

Design Specifications

Selection Criteria for Main Components

  • Spring hinges that can be flipped up against the weight of the knob.

Design Evaluation

Verification of main components

  • The spring hinges are verified based on the load moment, to see whether the dog moves away from the sensor.
    • Conditional Value:
      Total mass of dog and knob: m = 0.10kg
      Horizontal distance between hinge shaft and center of gravity of dog and knob: a 20.0mm
      Load of hinge spring: k = 0.40kgf
      Hinge spring load definition angle: θ = 270°
      Hinge spring load position: b = 16mm
      Number of hinge springs: n = 2pieces
      Hinge spring load in free condition: k0 = 0.10kgf
      Hinge spring angle in free condition: θ0=90°
      Target hinge angle: θ1 = 225°
      Gravitational acceleration: g = 9.8m/s2

      Hinge spring load at target angle: k1 = {(k - k0)/(θ - θ0)} x θ1 = {(0.4 - 0.1)/(270 - 90)} x 225 = 0.375kgf
      Total hinge spring load at target angle: k1' = k1 x n = 0.375 x 2 = 0.75kgf

      Moment by dog and knob: M1=m x g x a, hence, M1 = 0.1 x 9.8 x 20 = 2.0kgf・mm
      Moment by hinge: M2 = k1' x b, hence, M2 = 0.75 x 16 = 12.0kgf・mm
      From M1 < M2, the angle of the hinge at an unfixed state satisfies the target angle θ1 at which the dog moves away from the sensor.

Other Design Consideration

  • The mechanism is designed so that when flipped up, the spring hinge flips the total weight of the dog away from the sensor.
  • The photomicrosensor should be set to turn on when shielded from light, and the interlock

    A mechanism, used as a safety mechanism, that disables other operations when predetermined conditions are not satisfied.

    should be applied when the sensor turns off due to the door being open or failure of the sensor.
