As shown in the figure, the vacuum suction pad 70 is composed of a suction plate 72 and a suction plate.
Suction device 74 provided above 72, suction device 74 and suction plate
72 and a flexible pipe 76 connected to the flexible pipe 76. The suction disk 72 is generally made of rubber having elasticity, or rubber or sponge having a peripheral edge having elasticity. A hydraulic device (not shown) is provided below the suction device 74, and the lifting device can move the suction plate 72 up and down. The flexible pipe 76 communicates with the inside of the suction plate 72 and the suction device 74.

下となって現れる。(Problems to be Solved by the Invention) However, in such a conventional vacuum suction pad, although it can be applied to an object to be suctioned having a relatively hard surface, it wraps a liquid material, a granular material, a powder or the like. Various problems occur when the method is applied to a deformable object to be sucked. That is, when holding a deformable food product or the like packed with flour, raw noodles, miso, oil liquid, etc., the packing material of the material to be adsorbed which hits the peripheral edge (lip portion) of the suction disk 72 has a wrinkle and a vacuum. This causes a problem that the degree of decrease or the content flows in the suction board 72 due to the suction, and blocks the suction port in the suction board 72, so that the suction area is substantially reduced. Therefore, as described above, the decrease in the suction area and the degree of vacuum appears as a decrease in the lifting ability of the object to be sucked.

来のようなゴム弾力性、変形性に富んだものではなく、
変形しない硬質なものであることが重要とされる。(Operation) When the vacuum suction pad of the present invention holds a deformable adsorption object, first, the opening holding port of the pad can be deformed in a state where the inside of the opening is under a negative pressure or a state where the negative pressure is not applied. Applied to adsorbate. Next, when a negative pressure is applied to the inside of the opening through the suction port formed on the peripheral side wall in the opening or the bottom surface in the vicinity thereof, the object to be adsorbed deforms and flows, and a part of the object is at a predetermined depth. A part of the outer side of the opening abutted against the bottom surface of the opening, and a part of the outer part of the opening received a suction force drawn into the inside of the opening holding opening, and was strong on the periphery of the opening holding opening, and lost fluidity. Adhere in a state. Also, in this case, the periphery of the opening holding port is not rich in rubber elasticity and deformability as in the related art,
It is important that the material be hard and not deformed.

皺などができやすい。しかし、開口保持口周縁が硬質で

外に皺の発生影響がなく、しかも内容部の流動性を所定
の状態で確実に止めることができる。The object to be adsorbed is deformed, and the object having fluidity is mainly packaged with a resin film or the like. For this reason, when the to-be-adsorbed object is covered with the film, wrinkles and the like are likely to be formed at the peripheral edge. However, when the periphery of the opening holding port is hard, the film or the like has no surprising effect of wrinkling more than the conventional elastic material, and the fluidity of the contents can be reliably stopped in a predetermined state. .

重要なポイントは、パッドが一般の硬質な被吸着物に存

質的に形成し得ることであることが理解される。Therefore, a gap is formed in the opening near the peripheral side wall at the time of suction, and at least one suction port is provided so that the gap can be made negative pressure. It is not blocked by objects. Further, the surface of the object to be adsorbed facing the void portion is a kind of substantially fixed surface, which can substantially correspond to the adsorption area. Thus, it is understood that an important point of operation is that the pad can substantially form a fixed surface on a portion of the deformable object to be adsorbed, which is present on a common hard object to be adsorbed. .

物に固定面を形成する。Further, in the present invention, it is important to make the pad opening a dovetail groove in order to enhance the action. The term dovetail here generally refers to a state in which the diameter of the bottom surface is larger than the diameter of the opening holding hole. If the hole of the pad is formed as a dovetail, the film of the object to be adsorbed may be stretched widely at the bottom surface, and the contents of the object to be adsorbed may go all the way in and be locked at the inner periphery of the hole holding opening. The adhesion of the object to be adsorbed to the film or the like at the peripheral portion is increased in combination with the weight of the object to be adsorbed. Also,
The formation of a void portion in the opening is facilitated, and the fixed surface is reliably formed on the object to be adsorbed.

2、24と連通している。A male screw is engraved on the outer peripheral wall of the pad member 26, and a female screw on the inner peripheral wall of the ring member 28 is screwed to the male screw. The ring member 28 has a small-diameter opening 30 at the lower portion, and is made of a material having good workability such as Teflon. This ring member 28
Between the and the pad member 26, the above-mentioned bottom plate 32 is arranged,
The bottom plate 32 is sandwiched between them. A plurality of suction ports 34, 34,... Are formed near the periphery of the bottom plate 32, and the suction ports 34
It is in communication with 2, 24.

Since the suction port is formed so that the suction means communicates with the gap in the vicinity of the peripheral side wall in the opening formed by bonding to the bottom surface, the suction port is not blocked by the object to be adsorbed. In addition, in such a suction state, the periphery of the non-deformable suction holding port can surely make the suction target adhere closely, so that the degree of vacuum in the pad is not reduced. For this reason, in the vacuum suction pad of the present invention, the suction area and the suction capacity, which are the two major elements of the suction capacity, are maintained without the loss of the vacuum degree. An object can be securely held, suspended and transported.
