Vacuum Pad

Vacuum Pad for Packaging Bag

RoHS2 Compliant

Realizes followability to work-piece and posture stabilization during conveyance. Suitable for bag-like articles.

Advantages

Realizes followability to work-piece and posture stabilization during conveyance. Suitable for bag-like articles.

Realizes followability to work-piece and posture stabilization during conveyance.

Soft material is used for lip part, and hard material is used for bellows part.

Two selections of rubber hardness for lip part.

Soft material (lip color:blue) is for packaging bag which is made of thick vinyl or sheet.
Extra soft material (lip color:pink) is for deformable packaging bag.

Two selections of oversuction preventing adapter.

・Plane type is for hard packaging material (Pouch package, etc.).
・Spherical type is for soft packaging material (Shirataki bag, etc.).

Oversuction preventing adapter with stainless mesh is also prepared.

・Prevent the suction of foreign substances and avoid the troubles of vacuum system.
・Filtering accuracy:100μm (Reference value)

Two selections for bellows layer:3 and 5.

・Compared to 5 bellows type, 3 bellows type is shorter by approx. 25.3% in height.
・3 bellows type contributes the posture stability of a work-piece in high-speed conveyance.
・5 bellows type is suitable for liquid packaging which easily deforms.

For work-piece contacting parts, Food Safe Act. (Japan) complied and FDA equivalent materials(*) are used. *This product is not FDA certificated.

Detailed Safety Instructions

Warning

1.When installing the bulkhead type vacuum pad holder to the actual equipment, refer to the following table of the tightening torque of the bulkhead mounting nut of pad holder and tighten it using the appropriate tool, and confirm that there is no loosening.

2.When installing direct mount type pad holder, check the following tightening torque table, and tighten it using the appropriate tool, and confirm that there is no loosening.

3.For the direct mount vacuum pad holder, with parallel pipe thread type and with M8 or M14 metric thread type are sealed with an O-ring, and M5 or M6 metric thread type is sealed with a gasket. When installing the unit on the actual equipment, make sure that the contact area of the O-ring and gasket on the machine surface is smooth and free of scratches and dents.

4.Due to its characteristics, the theoretical suction force of this product may exceed the physical strength of the pad itself, depending on the degree of vacuum, a safety factor of at least 1/16 for horizontal lifting and 1/25 for vertical lifting should be used. Be sure to perform the adsorption test on the actual operating condition.

Caution

1.For the pads for packaging bag, use the allowable pressing stroke as a guide, do not crush the bellows too much. Excessive crushing may cause premature wear of the bellows, cracking of the lip, and deformation due to strain, which may result in suction failure.

2.Be sure to attach the oversuction preventing adapter to this product. If used without the oversuction preventing adapter, the vacuum pad may be deformed and cause suction failure.

3.When attaching or detaching the oversuction preventing adapter to or from the product, excessive pulling on the lip may cause damage to the lip.

4.Since the suction flow rate is structurally reduced with the oversuction preventing adapter with stainless steel mesh, perform the suction test on the actual operating condition.

5.Regularly check for clogging with the oversuction preventing adapter with stainless steel mesh. Clogging may cause poor performance or trouble. Clean or replace with new one if necessary.

6.Install the oversuction preventing adapter in the proper position referring to the following figure. If not installed in the proper position, suction failure may occur.

7.The spherical oversuction preventing adapter is mounted deeper than the pad suction surface, so that the ribs on the pad suction surface fall in one direction when the workpiece, which is flat and difficult to deform, is picked up, and a rotational load is applied. This rotational force can lead to loosening of the screw or damage to the mounting part. When suctioning a flat workpiece which is difficult to deform, use the flat suction prevention adapter.
