Abstract

PURPOSE: To provide a simple compact plate material sucker mover whereby a plate material, even without pressing a sucker surface of the sucker mover to the plate material and even when opened many fine holes between both obverse/reverse surfaces in the plate material, can be sucked and moved, by increasing an air suction amount from a surface which must suck the plate material in the plate material sucker mover. CONSTITUTION: A compressed air flow pipe 1 is arranged in a tubular body 2 so as to jet compressed air in an upper end direction of the tubular body 2 on almost an axial line in the lengthwise direction inside an intermediate part of the tubular body 2. A plate material sucker equipment 3, forming a lower end surface in a parallel surface to a surface of a moved plate material 4 which must be arranged downward, is peripherally provided in an adhesive condition in a lower end part of the tubular body so as to prevent narrowing a lower end part opening area of the tubular body and so as to position the lower end surface to a lower end opening surface of lower of the tubular body, and then a plate material sucker mover fixes the tubular body to a moving fixture 5, to be a collective unit of the plate material sucker mover with a plurality thereof combined in a parallel shape.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate adsorbing mover capable of moving and carrying a plate such as a ceramic substrate, a plastic plate, a metal plate, a paperboard, and a wooden plate to an appropriate place while sucking and adhering the plate, and having a structure. In addition to being simple and compact, the suction force is so strong that even if there are a large number of small holes between the front and back of the plate, which is the object to be adsorbed, or there is some unevenness on the surface, it can still be sufficiently adsorbed and moved. The present invention relates to a plate adsorption transfer device.

[0002]

2. Description of the Related Art Conventionally, as a device for adsorbing and moving a ceramic substrate or other plate, a suction cup connected to a vacuum generator through an exhaust conduit is pressed against the surface of the plate to adsorb the plate on the suction cup. Then, the suction cup and the plate body were pulled up and moved to an appropriate position.

[0003]

In a suction device with a suction cup connected to such a vacuum generator via an exhaust conduit, the pressure difference between the suction cup and the vacuum generator is less than 1 atm. In addition, since the pressure loss of the fluid in the relatively long exhaust conduit interposed between them is large, and the amount of air sucked from the suction cup is not large, the suction cup does not increase the amount of air adsorbed on the surface of the plate body to be adsorbed. When the initial pressing force is weak and the close contact between the plate and the suction cup is not so good, or there is a small through hole between the front and back of the plate or the plate surface has some irregularities, the plate It is prone to a problem that the plate cannot be adsorbed by the suction cup so that the plate can be lifted up. In addition, if the exhaust conduit has a large diameter in order to reduce the pressure loss of the fluid in the exhaust conduit and increase the amount of air sucked from the suction cup, the whole apparatus becomes bulky, which is inconvenient. . The present invention is an improvement of such a conventional plate suction device, which has a large suction air amount and a strong suction force, and can suck the plate without pressing the suction surface against the plate, and Even if there are many fine through holes or there are some irregularities on the surface of the plate, the plate can be adsorbed, and the plate can be carried to an appropriate place in the adsorption state, and the structure is simple and compact. The objective is to develop a simple plate adsorption transfer device.

SUMMARY OF THE INVENTION The present invention provides
The compressed air conduit 1 is configured so that compressed air can be blown out from the nozzle at the tip of the compressed air conduit 1 toward the upper end of the cylindrical body inside the intermediate portion of the cylindrical body 2 substantially on the axis of the longitudinal direction of the cylindrical body. And a lower end surface of the tubular member whose lower end surface is parallel to the surface of the movable plate member 4 to be arranged below. In a manner in which it is located at the same position as the lower end opening surface or a position lower than that, and in a manner in which the plate suction tool does not substantially narrow the opening area of the lower end portion of the cylindrical body, in close contact with the peripheral wall of the cylindrical body. It is a plate suction moving device in which the tubular body is fixed to the moving tool 5 while being provided around the lower part thereof.

In such a plate sucking / moving device, a moving plate 4 such as a ceramic substrate is moved below the lower end surface of the plate sucking tool 3 and close to the lower end surface of the plate sucking tool and the plate. When the compressed air is jetted toward the upper end of the cylinder from the tip end nozzle of the compressed air conduit 1 in the cylinder 2 of the plate adsorption mover, the compressed air is ejected toward the upper end of the cylinder. According to the principle, the lower part of the cylinder is depressurized and the outside air is strongly sucked from the lower end surface of the cylinder without any pressure loss, so that the movable plate is automatically attracted by the suction airflow. It comes to adhere to the lower end surface of the plate suction device. Then, by operating the moving tool 5, the plate to be moved is carried to a predetermined position in a state in which it is attached to the plate adsorbing tool, where the compressed air is ejected from the nozzle at the tip of the compressed air conduit. By stopping the operation, the plate body is detached from the lower end surface of the plate body adsorption tool and placed on the predetermined position, and the predetermined movement of the plate body is completed.

In this case, since the depressurized state generated in the lower part of the cylinder works to suck the outside air from the lower end of the cylinder without interposing any exhaust pipe, from the nozzle of the tip of the compressed air conduit. If the amount of compressed air to be jetted is increased, the amount of suction of the outside air can be increased correspondingly to increase the amount, and an exhaust conduit can be installed between the conventional vacuum generator and the suction cup that should be in close contact with the plate. Compared with the case of distributing,
In order to significantly increase the amount of outside air suctioned,
The suction operation was difficult with the conventional plate suction device, there is a little gap between the lower end surface of the suction cup and the surface of the moved plate, or the surface of the moved plate is covered with a printing resin. Sufficiently maintain the degree of vacuum or reduced pressure in the suction cup, such as unevenness due to scattering, and many fine through holes required for post-treatment of the plate body between the front and back of the plate to be moved. Even if it is difficult, the movable plate can be automatically and stably attached to the lower end surface of the plate suction tool without any trouble.

[0007] In this plate suction transfer device, as described above, the amount of outside air sucked from the lower end of the cylindrical body can be markedly larger than that of the conventional suction cup connected to the exhaust pipe. Even if the lower end surface does not have to be in close contact with the surface of the movable plate body (although it may be intimately close to the original surface), the movable plate body can be attached to the lower end surface of the plate body adsorption tool. As in the case of the plate suction device, a unit operation for pushing down the suction cup to bring it into close contact with the surface of the plate to be moved is not necessary in the suction operation.
In addition, the structure is as simple as combining a compressed air conduit with a tubular body, and it can be made as compact as low in bulk as a suction cup in a conventional plate adsorption device, so various existing devices can be used. It can be easily used instead of the suction cup. Further, the vacuum generating device and the exhaust pipe connected to it, which were indispensable in the conventional plate adsorption device, are omitted, and compressed air that is generally easy to obtain in a factory is used and the internal fluid is compressed. Since it is a plate adsorbing mover that requires only a compressed air conduit that requires a relatively small diameter, the equipment and its operating cost are very economical.

It should be noted that the plate suction device to be provided around the lower end of the cylindrical body of the plate suction mover enhances the mutual adhesiveness when the plate to be moved is sucked by the plate suction device, and the suction state is maintained. It is needless to say that it is preferable to be composed of an elastic body such as rubber or plastic or a flexible body for more stabilization. Further, it is preferable that the cylindrical body of this plate suction transfer device is a cylindrical body, but even if it is an elliptic cylinder or a polygonal cylinder that is slightly deformed, the function is not particularly affected.

According to a second aspect of the present invention, a plurality of plate bodies to be arranged in parallel are adsorbed and moved simultaneously, or a single plate adsorber has a large surface area that cannot be adsorbed and moved. It is an assembly of plate suction transfer devices for advancing and moving a plate transfer plate, wherein a plurality of plate suction transfer devices according to claim 1 are combined in parallel in the front-rear direction and / or the left-right direction. It is an assembly of body adsorption transfer devices. According to this plate adsorbing and moving device assembly, even a large number of plate members arranged in parallel in front and back or left and right while keeping an appropriate mutual distance, or even a plate member having a large front and rear width and a large lateral surface width,
As described above, it becomes possible to move the plate body surface portion by a predetermined distance while adsorbing the plate body suction tools at the lower end portions of the respective cylinder bodies.
