■How to use
Air Pincette with no Push Button Valve: VTA
■Work-piece will be sucked by vacuum pad, while blocking
the side hole during the supplyof the compressed air
72.5psi (0.5MPa). Work-piece will be released by
unblocking the side hole.
Air Pincette with Push Button Valve: VTB
■Work-piece will be sucked by vacuum pad, while pressing
the push button during the supply of the compressed air
72.5psi (0.5MPa). Work-piece will be released by releasing
the button.
1. Do not use machine to operate the push button. The button may be damaged.
2. Carry out the maintenance of the filter element periodically. The element is replaceable by detaching
the ejector of VTA or the holder of VTB. There is a possibility of dropping the performance by the filter
clogging.
3. Silencer element of VTB is not replaceable.
4. Use coiling tube for Air Pincette in order to minimize the load on Fitting.

Vacuum Pad Selection Guide
Selection Guide 1
▲
Select the diameter of vacuum pad from the formula ① and chart of the theoretical suction force ②
The theoretical suction force is determined from pad area and vacuum level. Calculated
value is for reference only, so carry out the evaluation under an actual operating condition.
The theoretical suction force is calculated under a static condition. Obtain an enough
margin, considering the weight of a work-piece and acceleration of lifting, pause and rotary
movement. Enough room is needed in deciding a number of pads and arrangement position.
① Calculation by formula
W =C ×P ×10.13 ×f
−
101
*1. Refer to the following chart for Sponge Series.(Internal diameter is used for calculation)
*2. Refer to the following chart for Flat Series.(Pad grooves are used for calculation)
*3. As for Bellows, Multi-Bellows, Soft, Soft Bellows and Ultrathin Series, their theoretical suction force may
exceed the strength of pad itself, depending on the vacuum level. Carry out the evaluation under an
actual operating condition.

Installing a fall prevention valve between a vacuum pad and a holder
prevents the troubles like system break down, minimizing the vacuum
drop of the whole system automatically by reducing suction flow of the
part where the work-piece falls from the vacuum pad (within the range not
causing any problem), or no work-piece is to be sucked.

Reference Guide for Vacuum Pad
Impact on pad
Avoid an impact or a large force on a vacuum pad, when it is
pressed against a work-piece. It may cause deformation, crack or
abrasion at an early stage of use. Adjust the pad position so that
the lip of pad touches lightly on a work-piece. Especially a small
type of vacuum pad should be positioned precisely.
Porous or perforated work-piece
Since the suction of a porous work-piece causes a drop of suction
force, select the proper specifications of vacuum system and secure
a larger effective cross-section area of the piping. Selecting a small
type of vacuum pad is one of solutions to reduce the air leakage.
Large and wide at plate work-piece
When lifting large size of glass board or circuit board, work-piece
may bend by the lifting acceleration or the self-weight. Select a
proper size of pad and positioning, considering an enough margin
of suction force.
Soft work-piece Work-piece with di󱐯erent heights
Select Long Stroke Series for work-pieces having different heights,
or piled-up work-pieces. Its stroke can absorb the difference in
height.
Inclined work-piece
Select Free Holder for an inclined work-piece.

Lifting work-piece, sucking the both side of it
Since all vacuum pad holders are designed for horizontal lifting,
consider the strength of holders and pads.
Work-piece
Lifting
Consider to reduce the stress
against holders and pads
by sucking the both sides of
work-piece.
Vacuum pad
Pad holder
Conveyance with rotary movement
When vacuum pad is fixed with a screw and has a rotary movement,
the pad may drop due to the loosened screw. Pay special attention
when the vacuum location of work-piece is off the center of work-
piece gravity.
Safety factor (1/8) of vertical lifting
needs to be applied in rotary
conveys or lateral movement
When soft work-pieces such as plastic bags, papers or thin boards
are sucked, work-pieces can be deformed or shrunk by vacuum
suction (Figure-1). Select smaller vacuum pads and reduce the
vacuum pressure. Smaller vacuum pads are suitable for plastic
bags and papers. When plastic / paper bags are opened by using
vacuum pads, shift the center of two vacuum pads slightly in order
to open them easily as Figure-2 shows.
