Refer to front matters 38 and 39 for Safety Instructions and pages844 to 846 for Vacuum Equipment Precautions.1. In cases where workpieces are heavy or dangerous, etc., takemeasures 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 andcracking of pads, and vacuum leakage from piping, etc., be certain toperform maintenance on vacuum equipment.1. The pad materials differ depending upon the operatingenvironment.An appropriate pad material should be selected. Furthermore, since vacuumpads are manufactured for use with industrial products, they should not havedirect contact with pharmaceuticals or food products, etc.2. Depending upon the weight and shape of the workpieces, thediameter, quantity and shape of pads will vary.Use the pad lifting force table for reference. Also, the pads selected willdiffer based upon conditions other than the above, such as the condition ofthe workpiece surface (presence or absence of oil or water), the workpiecematerial and its gas permeability. Confirmation is necessary by actuallyperforming vacuum adsorption testing on the subject workpieces.3. Use a buffer for adsorption on fragile workpieces.The cushioning by the buffer is necessary when there is variation in theheight of workpieces. When further positioning of pads and workpieces isdesired, a detent buffer can be used.4. The life of a buffer will be reduced if the lateral force is applied to the buffer shaft.Note that sometimes a load is applied to the buffer by a piping tube (pullingor pressing, etc. in a lateral direction).5. Do not apply an impact or large forces to a pad when adsorbing a workpiece.This will cause deformation, cracking and wear of the pad to be accelerated.The stiffening ribs, etc. should touch lightly, while staying within the padskirt's deformation range. Positioning should be performed accurately.Especially in the case of small diameter pads.6. When transporting in an upward direction, factors such as acceleration, windpressure and impact force must be considered in addition to a workpieceweight.Use caution particularly when lifting items such as glass plates and circuitboards, because a large force will be applied by the wind pressure. When aworkpiece which is oriented vertically is transported horizontally, large forcesare applied by acceleration when movement is started and stopped. Further,in cases where the pad and a workpiece can slip easily, accelerations anddecelerations of horizontal movement should be kept low.7. When transporting flat workpieces that have large surfaceareas using multiple pads, care must be taken when arrangingthe pads to balance the workpiece.1. Perform pad maintenance regularly.Since pads are essentially rubber, deterioration is unavoidable. The rate ofdeterioration depends upon factors such as conditions of use, environmentand temperature. Regular maintenance should be performed. If any damage,splitting, cracking or abrasion has occurred in a pad which appears to beharmful, replace it immediately. Also, take care not to damage the outside ofthe pad.1121ZAZXZRZMZMAZQZHZUZLZYZFZPSPZCUKAMJAMVAEPHEPRelatedEquipment
