    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.

  • * 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
    • Using suction cups, various plastic work pieces with different step heights can be transported without changing the setup.
  • Operation
    • When work pieces vary, changing the suction cups is unnecessary. The suction cups unit slide up and down the spline shaft to absorb the different heights of the work pieces. Horizontal transportation of the work piece is conducted by fixing the upper part of the spline shaft with an air chuck.

Points for use

  • Transportation of irregular shaped work pieces in their horizontal posture is possible by chucking the slide of the suction cup.

Target workpiece

  • Shape: Plastic cases with height differences.
  • Size: W 120 x D 100 x H 15 (allowable difference in step difference 10 mm)
  • Weight: 800 g

Design Specifications

Operating Conditions or Design Requirements

  • Suction cup stroke 15 mm
  • Suction cup maximum reaction force: 7.93N x 2 (including weights of the guide, etc.)
  • Hand gripping force: About 70N (air pressure 0.4MPa)
    70×70％=49N
  • External size: W 100 x D 60 x H 230 mm

Required Performance

  • Allowable transportable load: 8 N

Selection Criteria for Main Components

  • Gripping force of the air chuck: >= 46.2N
    Select an air chuck with a gripping force of 49 N.

Design Evaluation

Verification of main components

  • Verify the transportable load limit by the air chuck for the feasibility of transporting the work pieces.
  • Check the allowable transportable weight by air chuck gripping
    • Conditional values: workpiece weight: M1 = 800g = 0.8kg, weight of a structure gripped by the air chuck: M2 = 0.4kg, gravitational acceleration g = 9.8 m/s², friction coefficient μ = 0.5 (rubber vs. metal), spring constant of the spring: k = 0.2 N/mm, maximum deflection of the spring: L = 21.5 mm, gripping force of the air chuck: H = 49 N
    • Maximum downward load by the springs (2 pieces): S = k x L x 2 = 0.2 x 21.5 x 2 = 8.6N
    • Downward load by the structure and springs: W = M2 x g + S = 0.4 x 9.8 + 8.6 = 3.9 + 8.6 = 12.5 N
    • Maximum transportable weight with the chuck: P = H x μ = 49 x 0.5 = 24.5 N
      Allowable transportable weight: Q = P - W = 24.5 - 12.5 = 12.0 N
    • Downward load of the workpiece: N = M1 x g = 0.8 x 9.8 = 7.8N This corresponds to 65% (=7.8/12×100) of the allowable transportable weight, and thus, the workpiece can be transported.
  • Checking the allowable transportable weight of the suction cup
    • Conditional values: Pad size = φ 20mm ∴ pressure receiving area S ＝ 3.14cm², vacuum pressure P ＝ - 80 kPa, safety factor t = 4
      Sling up capacity: W [N] ＝ P x S x 0.1/ｔ＝ 80 x (3.14 x 4pieces) x 0.1/4 = 25.1N

      ⇒Allowable transportable weight of the air chuck 24.5N　≦　allowable transportable weight of the suction cup 25.1N Thus, the workpiece can be transported.

Other Design Consideration

  • By sliding the suction cup up and down using the guide, irregular shaped work pieces can be transported.
    The orientation of irregular shaped work pieces can be retained by holding and fixing the slide with a chuck.
  • Rubber pads are affixed on the inner sides of the chuck grips to retain the position of the spline shaft.
