Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction jig for separating and taking out one by one from a front row of a plurality of vertically stacked glass plates.

[0002]

2. Description of the Related Art When taking out a plate-shaped body one by one from the front row of a plurality of plate-shaped bodies stacked vertically without using a large-scale device such as an automatic machine, one by one is manually peeled and taken out. Various methods and jigs are known, such as a method, a method of manually adsorbing and taking out a plate-shaped body with a handy type suction cup.

Among these, as the one using the handy type suction cup, as shown in, for example, Japanese Utility Model Laid-Open No. 4-83589, a flexible circular suction plate is stretched on the recessed surface side of the suction cup body to form a suction cup. The tip of the shaft that penetrates the center of the body so as to be movable in the axial direction is connected to the suction plate, and the end of the shaft protruding outside the suction cup body is swingingly operated to suck the suction plate through the shaft. There is a description of a handy type sucker in which a cam lever for pulling the inside of the sucker body is pivotally stopped.

[0004]

As a case of simply taking out the plate-shaped bodies one by one from the front row of a plurality of vertically stacked plate-shaped bodies without using a large-scale device such as an automatic machine, an actual flat blade 4 Regarding the handy type sucker disclosed in Japanese Patent Publication No. 83859, the front row of a plurality of vertically stacked plates is
When sucking or releasing sheets, one side must support the suction cup and the other hand must operate the cam lever.
It is difficult to operate with one hand.

Further, when the upper part of the first plate-like member from the front row is pulled to the front side after suction, when separated from the second and subsequent plate-like members, the gap between the first and second plates is momentarily negative. In order to prevent the second and subsequent plate-like bodies from collapsing together with the first plate-like body due to pressure, the second and subsequent plate-like bodies are often held by hand, and the separated plate-like body is also used. In order to process the body by handling, when removing the suction cup for adsorbing the plate-shaped body, it is necessary to support the suction cup with one hand again and use both hands to return the cam lever with the other hand, so workability is poor, It took time and there was a problem in terms of work tact.

Further, in the method of manually peeling one by one and taking it out, it is slightly slanted laterally in order to make a margin for catching on the edge of the first plate, but when the plate is a glass plate. , The edge of the glass plate may scratch the surface of the second glass plate, and it takes a lot of time and effort to separate only the first glass plate without providing a catching margin, tact, operability, There was a problem that work efficiency was poor.

[0007]

In order to solve the above problems, the present invention is a lightweight, compact, handy type that can be operated with one hand, and has operability, workability, and tact when sucking or releasing onto a plate-like body. For the purpose of a suction jig that can handle plates while holding the jig, the upper part of the front row of a plurality of vertically stacked plates is sucked and the second and subsequent sheets are adsorbed. In the suction jig that separates the plate-shaped body from, the suction pad, the airtight chamber connected to the suction pad via the air pipe, and the elastic force of the spring presses the spherical body against the suction port to constantly close the suction port. The airtight chamber includes a two-port valve that opens the intake / exhaust valve when the pressure is positive, a release button that opens / closes the intake / exhaust valve, and a tubular member fixed to the two-port valve and the suction pad. By pressing the suction pad on the body, the plate-shaped body is sucked, By pressing the release button so as to release the plate member, also the plate-like member to provide a suction jig is a glass plate.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The spherical force is pressed against the suction port by the spring force of the spring to normally close the suction port, and when the airtight chamber is at a positive pressure, the spherical body is pushed down to open the suction port. A two-port valve consisting of an intake / exhaust valve and a normally open port, and a two-port valve consisting of a release button for opening / closing the intake / exhaust valve are screwed with a tubular member on the inlet side threaded portion of the cylindrical main body. The joints were screwed into the normally open ports.
On the other hand, the inner side of the cylindrical core metal bonded to the central core of the suction pad and the connection fitting provided with the air inlet and outlet air of the suction pad on the central shaft are screwed together, The joint is screwed into the inlet of the inflow passage provided on the side surface of the connection fitting, and
The joints provided on the port valve side were connected by an air pipe, and the fitting was fixed to the tubular member.

When the suction jig of the present invention having the above-mentioned structure is held by one hand and the suction pad of the suction jig is pressed against the upper part of one of the front rows of the plurality of vertically stacked plate-like members,
Due to the compression deformation of the suction pad made of elastic rubber, the air in the suction pad is sent into the airtight chamber through the air pipe,
When the pressure in the airtight chamber becomes positive and the spring force of the spring pushing up the spherical body blocking the lower part of the inlet of the airtight chamber exceeds the pressure of the airtight chamber, the spherical body is pushed down and the inlet is once opened. Then, when the atmosphere flows into the airtight chamber and the pressure in the airtight chamber decreases, the suction port is closed again by the elastic force of the spring. On the other hand, since the suction pad is made of elastic rubber, it will return from the compressed state if the pressing on the plate is stopped, so the inside of the suction pad and the airtight chamber will be negative pressure, and the suction pad will be in close contact with the plate. Becomes

Next, from the state of adsorbing the plate-like body,
When releasing, just press the release button and the tip of the release button pushes down the spherical body that closes the suction port.By creating a small gap, the outside air is taken in from the gap of the suction port instantly, and inside the suction pad. Then, the pressure inside the airtight chamber is made equal to the pressure of the outside air to release the adsorption of the plate-like body.

Since the suction jig of the present invention is lightweight and compact, when one of the frontmost rows of a plurality of vertically stacked plate-like bodies is slightly tilted to the front side by suction, the plate-like shape is obtained with the other hand. While supporting the body, press the release button with the thumb of the hand holding the suction jig to release the suction of the plate-shaped body, and the suction jig becomes a closed loop shape with the connection fitting, the tubular member, the 2-port valve, and the air pipe. Therefore, it is possible to handle the plate-shaped body with both hands while hooking it on the finger as it is.

FIG. 4 is a perspective view showing a state in which a suction jig is used, and FIG. 4 is a perspective view showing a state where a plate-like body is separated using the suction jig which is an embodiment of the present invention, FIG. 5 shows a sectional view of a suction jig which is another embodiment of the present invention.

First, as the constitution of the present invention, as shown in FIG. 1, a commercially available normally closed 2-port valve 5 which is opened only when a push button is pressed is prepared. The two-port valve 5 has a suction port having a narrow inner diameter at a lower portion of a substantially cylindrical shape, a spherical body 8 that abuts a lower portion of the suction port 9, a spring 10 that presses the spherical body 8 against the suction port 9, and a substantially cylindrical shape. A normally open port 11 provided on the side surface of the central part of the shape and a release button 12 provided with a main shaft 13 for pushing down the lower spherical body 8 are provided above the cylindrical shape. It has a structure that is constantly pushed up by spring force and is sealed so that there is no air leakage.

As shown in FIGS. 1 and 2, the two-port valve 5
The cylindrical member 19 is screwed onto the outer peripheral threaded portion of the cylindrical main body on the side of the suction port 9, and the air pipe 1 is attached to the normally open port 11.
8 joints 16 for connection were screwed together. On the other hand, the inside of the cylindrical core metal 2 adhered to the inner diameter side of the core portion 1a at the center of the suction pad 1 and the connection in which the air inflow passage 3a for inhaling the air in the suction pad 1 is provided at the central shaft portion. The metal fitting 3 is screwed together, an O-ring 21 for sealing is provided between the connection metal fitting 3 and the core metal 2, and a joint 17 screwed into the outlet 3b of the inflow passage 3a provided on the side surface of the connection metal fitting 3. Then, the joint 16 provided in the normally open port 11 is connected by an air pipe 18, and the connecting fitting 3 is screwed to the protruding portion 20 fixed to the tubular member 19.

Next, the operation of the suction jig 4 of the present invention will be described in detail. When the suction jig 4 of the present invention is held with one hand and the suction pad 1 of the suction jig 4 is pressed against the upper part of one of the front rows of the plurality of plate-like bodies G stacked vertically, the suction pad made of elastic rubber Due to the compressive deformation of 1, the air in the adsorption pad 1 passes through the inflow passage 3a in the connecting fitting 3, passes through the air pipe 18, and is fed into the main body airtight chamber 6 of the two-port valve 5. The pressure in the airtight chamber 6 becomes a positive pressure, and when the pressure in the airtight chamber 6 exceeds the spring force of the spring 10 pushing up the spherical body 8 blocking the lower portion of the suction port 9 below the airtight chamber 6, the spherical When the body 8 is pushed down and a gap is formed between the suction port 9 and the spherical body 8, the atmosphere flows into the airtight chamber 6 through the tubular member 19, and when the pressure in the airtight chamber 6 drops to atmospheric pressure, the elasticity of the spring 10 is reduced. The suction port 9 is closed again by the force. On the other hand, since the suction pad 1 is made of elastic rubber such as urethane rubber, silicon rubber, nitrile rubber, and viton rubber, if the pressing on the plate-shaped body G is stopped, the suction pad 1 tries to recover from the compressed state. And the inside of the airtight chamber 6 becomes negative pressure this time, and the suction pad 1 is brought into close contact with the plate-shaped body G.

Next, when releasing the plate-shaped body G from the adsorbed state, when the release button 12 is pressed, the tip of the main shaft 13 fixed to the central axis of the release button 12 moves inside the suction port 9 of the main body. Passing down and pushing down the spherical body 8, the suction port 9 and the spherical body 8
Make a slight gap between them. The outside air is taken in from the gap in an instant, and the suction pad 1 and the airtight chamber 6 are made to have the same pressure as the outside air to release the adsorption of the plate-shaped body G.

Next, an example of use of the suction jig 4 of the present invention will be described. Holding the suction jig 4 of the present invention with one hand,
The suction pad 1 of the suction jig 4 is pressed against the upper part of the front row of the plurality of glass plates G vertically stacked as shown in FIG. ,
If there is a gap between the top and the second sheet, hold the other side of the glass plate with the other hand so that it does not fall over and hold your hand between the top of the first and second sheets. Defeat until there is a gap to enter. If the second and subsequent glass plates fall together, return them to their original positions and pull again. In this way, when the first glass plate G in the front row is separated toward the front side, the release button 12 is pressed with the thumb of the hand holding the suction jig 4 while supporting the glass plate G,
The adsorption of the glass plate G is released. After releasing the suction of the glass plate G, the handling such as transferring the glass plate G in the front row can be performed with the suction jig 4 still hooked on the finger.

The suction jig 4 of the present invention is lightweight and compact, and the suction jig 4 has a closed loop shape by connecting the connection fitting 3, the projection 20, the tubular member 19, the two-port valve 5 and the air pipe 18. Since it is not used, it is not necessary to leave it in a place where it is hooked on the finger as shown in FIG. 3 and to put it in another place when not in use. The workability is very good because it can handle the shape.

Although the preferred example has been described above, the present invention is not limited to this, and various applications can be considered. As another embodiment, as shown in FIG. 5, a connecting metal fitting 3 ′ is screwed onto an adhesive core metal 2 on the core portion 1 a of the suction pad 1 to seal the connecting metal fitting 3 ′ and the core metal 2 with each other. O-ring 2
1 is provided, and the other end of the connecting fitting 3'is directly connected to the normally open port 11 of the 2-port valve 5, and the inflow path 3a 'of the connecting fitting 3'is the suction pad 1 and the 2 port. The valve 5 was communicated with the airtight chamber 6. An O-ring 22 for sealing was provided between the connection fitting 3 ′ and the normally open port 11 of the 2-port valve 5. In this case, the air piping as shown in FIG. 1 becomes unnecessary.

Further, in the case of the embodiment shown in FIG. 1, the protrusion 20 and the connecting fitting 3 may be integrated without screwing separate members. Further, as the plate-shaped body G, in addition to the glass plate,
It can also be applied to resin plates such as plastics and metal plates such as iron plates.
