される。また、下面周囲に設けられた溝部５ａは
溝部５より細く、浅く構成され、吸着効果が高め
られるよう構成されている。 Furthermore, an orifice 8 is formed in the ventilation path 6, and the amount of ventilation to the grooves 5, 5a is adjusted to an appropriate amount. Further, the groove portion 5a provided around the lower surface is configured to be thinner and shallower than the groove portion 5, and is configured to enhance the suction effect.
また、吸気時に溝部５，５ａの吸気を迅速に行
うため、溝部５と通気路４間にチエツクバルブ９
を設けてもよい。 In addition, in order to quickly draw air into the grooves 5 and 5a during intake, a check valve 9 is installed between the groove 5 and the ventilation path 4.
may be provided.
つぎに、通気路４の外周面の開口部４ａには袋
状の可撓性シール部材１０が全周にわたつて設け

内部に送り込むと外側に膨出するよう構成されて
いる。もつとも、上記癖は逆であつてもよい。 The flexible sealing member 10 is made of rubber, plastic, etc., and is configured so that its tip is normally lowered to the lower surface of the pallet 1, and bulges outward when compressed air is sent inside. has been done. However, the above habit may be reversed.
上記構成のパレツト１は第４図示のごとく、ベ
ース２上をタイミングベルト１１によりスライド
させられるよう構成される。 The pallet 1 having the above structure is constructed so as to be slid on the base 2 by a timing belt 11, as shown in the fourth figure.
もつとも上記スライドはボールネジとスクリユ
ー、ラツクとピニオン、リニアモーター、その他
各種の方法で行うことができる。 Of course, the above-mentioned sliding can be performed using a ball screw and screw, a rack and pinion, a linear motor, and various other methods.
上記いずれの方法にあつても、パレツト１とベ
ース２間には３〜５ミクロン程度のクリアランス
が生ずるよう構成される。 In any of the above methods, a clearance of about 3 to 5 microns is created between the pallet 1 and the base 2.
上記構成の本発明はパレツト１のスライドに際
してはまず、給気及び吸気孔７から圧縮空気が送
り込まれる。 In the present invention having the above structure, when the pallet 1 is slid, compressed air is first fed through the air supply and intake holes 7.
すなわち、コンプレツサー等（図示せず）から
圧縮空気を送り込むと、該圧縮空気はオリフイス
８の作用で、まず通気路４を通つてその開口部４
ａから袋状の可撓性シール部材１０の内部に供給

ス８を通つて溝部５，５ａに供給され、パレツト
１とベース間に平均的に噴射されて空気膜が構成
され、結果的にパレツト１が数ミクロン持ち上げ
られた状態となる。 That is, when compressed air is sent from a compressor or the like (not shown), the compressed air first passes through the air passage 4 and enters the opening 4 due to the action of the orifice 8.
It is supplied into the inside of the bag-shaped flexible sealing member 10 from a, and bulges out to the flexible outside and is separated from the base 2 far away. At the same time, the compressed air is supplied to the grooves 5 and 5a through the ventilation passage 6 and the orifice 8, and is injected evenly between the pallet 1 and the base to form an air film, and as a result, the pallet 1 is lifted by several microns. The state will be as follows.
すなわち、可撓性シール部材１０を外側に膨出
させた後は全ての圧縮空気が溝部５，５ａへ供給
され、上記空気膜の構成に費やされる。 That is, after the flexible sealing member 10 is bulged outward, all the compressed air is supplied to the grooves 5, 5a and is used to form the air film.
つぎにタイミングベルト１１によりパレツト１
が所定位置までスライドさせられる。その際上記
空気膜の作用で従来のごとき摩擦抵抗は全くない
ものである。 Next, the pallet 1 is removed by the timing belt 11.
is slid into position. At this time, due to the action of the air film, there is no frictional resistance as in the conventional case.
そして所定位置までスライドさせたら、タイミ
ングベルト１１を止め、同時に給気及び吸気孔７
から吸気が行われる。 After sliding it to a predetermined position, stop the timing belt 11 and at the same time open the air supply and intake holes 7.
Inhalation is performed from

と外気とを遮断する。 Due to the intake air, the air film structure disappears, and the pallet 1 comes into close contact with the base 2. Then, the air inside the bag-shaped flexible sealing member 10 is also sucked in, and the tip of the flexible sealing member 10 is lowered and comes into close contact with the upper surface of the base 2, and the grooves 5, 5a
and outside air.
もつとも、上記パレツト１とベース２の密着に
より、溝部５，５ａと外気はほとんど遮断されて
いる。 However, due to the close contact between the pallet 1 and the base 2, the grooves 5, 5a are almost completely shut off from the outside air.

されるものである。 Furthermore, the air in the grooves 5, 5a is taken in from the ventilation path 6 and the check valve 9, and the air in the grooves 5, 5a is
The pallet 1 exhibits a suction cup effect, and the degree of adhesion of the flexible seal member 10 is further increased, so that the entire lower surface of the pallet 1 becomes a suction area, and the stationary state is firmly maintained.
したがつて、パレツト１上でワークの加工ある
いはパレツト１上の治具、工具類を稼動させても
パレツト１が移動等させられることが全くないも
のである。 Therefore, even if workpieces are processed on the pallet 1 or jigs and tools on the pallet 1 are operated, the pallet 1 is never moved.
