Description

[Detailed description of the invention] [Field of industrial application] The present invention is a suction system used to hold plate-shaped objects, particularly flat or curved glass plates, resin plates, etc., under reduced pressure and transport them to a predetermined position. Regarding the suction tool of the device,
More specifically, the present invention relates to a suction tool that has a simple structure and is equipped with a mechanism that can follow the shape or posture of a plate-like object.

[Conventional technology]

BACKGROUND ART Conventionally, when moving a plate-shaped object, particularly a glass plate, etc. from a conveyance line to a pallet or vice versa, a vacuum suction device is often used to suck and hold the glass plate and transport the glass plate in a suspended manner. At this time, the plate-like body generally has a large area and is thin, and the plate-like body often tilts, bends, or flexes, and this state changes during movement, sometimes causing a phenomenon in which the plate-like body appears to dance. This may cause the plate-shaped body to fall off or break, or cause surface scratches, and various proposals have been made to counter these problems, such as attaching a large number of suction tools. For example, JP-A-51-72058 describes a vacuum suction pad device, which is a transfer machine capable of suspending and conveying highly elastic iron plates, plastic plates, etc. A structure is disclosed in which a pipe is connected and an expansion spring is inserted inside the pipe to inflate the center so that the suction pad can freely swing.
The publication describes a vacuum suction cup, which is used, for example, in a vacuum suction supply device such as a press to suction a blank and transfer it to a predetermined position, and the cup body is made of rubber or a similar flexible material. Various devices are known, including one in which a sufficient adsorption force is exerted by integrally providing radial reinforcing ribs with a peripheral edge left on the inner surface.

[Problem that the invention attempts to solve]

The conventional device described in JP-A No. 51-72058, as mentioned above, is not necessarily simple in structure, is not suitable for transporting heavy objects, and is expensive to manufacture. In addition, the one described in Utility Model Application Publication No. 18879/1987 may have an increased adsorption force, but it does not have a mechanism to follow the deflection of the plate, and in any case, However, these methods are not fully satisfactory for the suction suspension conveyance of flat or bent plate-like objects that are bent, deflected, or tilted.

[Means for solving problems]

The present invention was developed in view of these drawbacks of the conventional suction tool, and by making the reinforcing member integrated with the suction tool flexible, it can be used reliably even on plate-shaped objects that are prone to bending, bending, or tilting. To provide a suction tool that allows safe suction suspension transportation.

That is, the present invention provides a suction tool consisting of a cup body made of rubber or flexible resin having a longitudinal cross-sectional plate shape and a rib portion, and a reinforcing member integrally molded with the cup body, in which the reinforcing member is divided into concentric circles. The present invention provides a suction device characterized in that:

Here, the reinforcing member can be a core material made of metal such as iron, stainless steel, or aluminum, hard resin, or composite material, and is integrated so as to be exposed facing the back of the cutlet body. It is a good thing. In particular, it is preferable to integrally mold a portion of the reinforcing member, including the divided portion, into the cup body. Further, the reinforcing member is divided concentrically and locally connected to such an extent that each of the members is flexible and does not lose its flexibility, and the locally connected member is However, as long as each of the divided reinforcing members is divided within a substantial range that does not restrict movement in the vertical direction, the divided part can be flexible and flexible at any time. A spring plate-like portion may be provided, and the position of the spring plate-like portion in the longitudinal section of the divided portion may be any position from the back side of the cup body to the inner side, and the material of the spring plate-like portion may be reinforced. It is preferable to use one that is the same as the other member and integrated, but is not particularly limited. Furthermore, by providing a convex portion on the inner surface of the cup body corresponding to the divided portion of the reinforcing member and reinforcing the flexible portion of the cup body, the thickness of the entire cup body can be reduced, which is preferable. be. Furthermore, the shape of the reinforcing member divided portions is made concentric circles in order to be able to respond uniformly and freely in all directions, and the spacing and number of divided portions are not particularly limited, but the reinforcing effect may be lost. Needless to say, it should be kept to a minimum.

Further, the cup body made of rubber or flexible resin and having a rib-shaped vertical section is made of, for example, neoprene rubber, polyurethane resin, or the like.

[Effect]

As mentioned above, the present invention divides the reinforcing member of the suction tool into concentric circles, so that in addition to the flexible rib part, the concentric flexible part maintains strength in the cup body. Since the reinforcing member fixed to the intake pipe, which is the center of the cup body, is fixed, the outer periphery of the reinforcing member fixed to the intake pipe, which is the center of the cup body, is fixed, and its outer periphery is shaped like a plate, bending, deflecting, tilting, etc., or the so-called dancing phenomenon. The device can flexibly move and follow the movement of the plate-shaped object, and the work of suctioning and suspending the plate-shaped object requires easier adjustment, and the number of suction devices installed is small, making it lightweight and simple. The detachment and fall of the body can be prevented, and the pressure bonding force during suction pressure bonding is improved and becomes sufficient, which reduces the cost of the suction device and eliminates surface scratches or damage to the plate-shaped body.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a vertical cross-sectional view showing a state in which the tip of the rib portion 6 of the suction tool 1 of the present invention is in contact with the plate-shaped body 2 . A portion of the reinforcing member 4 consists of a fixed part including a rising part and a movable part having a doughnut-shaped plate shape, separated concentrically by a dividing part 5, that is, a fixed part including the dividing part 5, and The flat plate-like part of the movable part is integrally molded so as to be embedded in the cup body 3, and on the back side 9 of the cup body 3, there is an intermediate part having a through hole 8 in the rising part of the center of the reinforcing member 4. It is connected to the intake pipe 7 through a member, and further communicates with a suction device (not shown), and connects the inner surface 10 of the cup body 3 and the plate-shaped body 2.
The plate-shaped body is designed to adsorb or release gas by sucking and exhausting gas in a closed space formed by the surface of the plate.

Note that the thickness of the cup body can be reduced by providing the convex portion as needed.

[Effect of idea]

As is clear from the above description, according to the present invention, even if the plate-shaped body bends, bends, tilts, or dances, the cup itself is flexible, so the suction tool can follow it, and it can prevent it from falling. , which enables reliable, safe and efficient work, prevents quality deterioration, and improves yield.
It is also useful for automation. Furthermore, even heavier, more flexible, larger-area, irregular-shaped objects such as bent glass plates can be suctioned and conveyed reliably and safely, making it possible to be adopted in a wide range of fields. be.
