qIn cases where the work pieces are heavy or dangerous, etc.,

take measures to address a possible loss of adsorption force

(installation of drop prevention guides, etc.).

In the case of transportation by vacuum adsorption using vacuum

pads, adsorption force is lost when there is a drop in vacuum pressure.

Furthermore, since vacuum pressure can also deteriorate due to wear

and cracking of pads, and vacuum leakage from piping, etc., be certain

to perform maintenance on vacuum equipment.

qThe pad materials differ depending upon the operating

environment.

An appropriate pad material should be selected.

Furthermore, since vacuum pads are manufactured for use with

industrial products, they should not have direct contact with

pharmaceuticals or food products, etc.

wDepending upon the weight and shape of the work pieces, the

diameter, quantity and shape of pads will vary.

Use the pad lifting force table for reference.

Also, the pads selected will differ based upon conditions other than the

above, such as the condition of the work piece surface (presence or

absence of oil or water), the work piece material and its gas

permeability. Confirmation is necessary by actually performing vacuum

adsorption testing on the subject work pieces.

eUse a buffer for adsorption on fragile work pieces.

The cushioning by the buffer is necessary when there is variation in

the height of work pieces. When further positioning of pads and work

pieces is desired, a detent buffer can be used.

rThe life of the buffer will be reduced if lateral force is applied

to the buffer shaft.

Note that sometimes a load is applied to the buffer by a piping tube

(pulling or pressing, etc. in a lateral direction).

tDo not apply an impact or large forces to a pad when

adsorbing a work piece.

This will cause deformation, cracking and wear of the pad to be

accelerated. The stiffening ribs, etc. should touch lightly, while staying

within the pad skirt's deformation range. Positioning should be

performed accurately. Especially in the case of small diameter pads.

yWhen transporting in an upward direction, factors such as

acceleration, wind pressure and impact force must be

considered in addition to the work piece weight.

Use caution particularly when lifting items such as glass plates and

circuit boards, because a large force will be applied by wind pressure.

When a work piece which is oriented vertically is transported

horizontally, large forces are applied by acceleration when movement is

started and stopped. Further, in cases where the pad and work piece

can slip easily, accelerations and decelerations of horizontal movement

should be kept low.

uWhen transporting flat work pieces that have large surface

areas using multiple pads, care must be taken when arranging

the pads to balance the work piece.

qPerform pad maintenance regularly.

Since pads are essentially rubber, deterioration is unavoidable. The rate

of deterioration depends upon factors such as conditions of use,

environment and temperature. Regular maintenance should be

performed. If any damage, splitting, cracking or abrasion has occured in

a pad which appears to be harmful, replace it immediately. Also, take

care not to damage the outside of the pad.
