がある。For example, a suction means provided with a suction pad is often used to convey a thin plate material or the like. Various techniques relating to this adsorption means have been proposed, and Japanese Patent Application Laid-Open No. 57-17432 is one of them. In the suction means disclosed in the publication, the tip surface of the suction pad is a flat surface, and an annular suction port is provided at a certain position in the radial direction, and suction force acts on this suction port. It is supposed to do. In this one,
There is an advantage in that a foil is partly displaced by the vacuum acting on the suction port and only one sheet is adsorbed well and conveyed.
ところが、前記吸着パッドは、専ら吸引口のみによる吸
着によるものであるため、吸着対象である板材等が油引
きのものであると滑ってずれ、バランスが崩れて搬送に
失敗するおそれがある。However, since the suction pad is exclusively sucked by the suction port, if the plate material or the like to be sucked is oiled, there is a risk of slipping and slipping the balance and failing to convey.
前記事情に鑑みて、この発明は、対象物を位置ずれなど

着して、常に安定した搬送を行うことができる。In order to achieve the above-mentioned object, at least the suction portion of the tip is made of an elastic material having an annular cross section,
In the suction pad in which the air inside the suction portion is sucked and removed, the suction portion is sucked to the object to be sucked, and the concave portion is formed in the annular suction surface which is the tip surface of the suction portion. Is formed, the suction surface is pressed against the object to be sucked to remove the internal air, and by releasing it, a suction pad is formed. Use as a summary. The recess is a small hemisphere, and a large number of rows are provided in the circumferential direction of the suction part to form a row, and since this row is arranged in multiple rows in the radial direction, the target object can be securely positioned without displacement. It can be adsorbed and can always be stably conveyed.
以下に、この発明を、その実施例をあらわした図面を参
照しつつ詳しく説明する。Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment thereof.

分４の先端面が丸い環状をした吸着面５とされている。1 to 3 show an embodiment of a suction pad according to the present invention. As shown in these figures, the suction pad is entirely made of a rubber material, a suction cylinder 1 is provided on an upper portion thereof, and a hemispherical plate portion 2 is provided on a lower portion thereof, which are integrally formed. Has been done. A passage inside the suction cylinder 1 connects a vacuum device (not shown) to the internal space 3 of the board 2. The board part 2
The front end of the suction portion 4 is a suction portion 4, and the tip surface of the suction portion 4 is a suction surface 5 having a round ring shape.
ところで、前記吸着面５には、半球状の断面形状をした

いる。By the way, a large number of concave portions 6 having a hemispherical cross-sectional shape are arranged on the suction surface 5. Each recess 6 has a circular opening whose opening edge is continuous when viewed from the bottom surface, and as shown in FIG. 1, it is the radial direction between the inner peripheral edge and the outer peripheral edge of the suction surface 5. Are arranged in three rows, and they are arranged in a zigzag pattern in the circumferential direction.

ることができる。As described above, in the suction pad according to the present invention, the concave portions are arranged on the suction surface which is the tip of the suction portion, and as shown in FIG. The suction part 4 is elastically deformed and is shown in FIG.
As shown in (c), the inside air is removed, and then the pressing is released, so that the inside becomes a negative pressure state as shown in FIG. As a result, the suction surface 5 is attracted to the object by the negative pressure in the recesses 6 ... And the vacuum device is operated in that state, so that the air in the space 3 in the board portion 2 is removed, and The adsorption action of is exhibited. In this way, since the pre-suction by the concave portion can be performed separately from the original suction, the suction state becomes a two-step and composite state, and the sheet material is surely sucked to the object and is oiled. Also, it is possible to surely suck and convey the sheet without any displacement.
この発明にかかる吸着パッドは、以上みてきたように構
