The present invention provides a cassette for accommodating a plurality of plates having a larger vertical and horizontal dimension than the thickness thereof, such as a glass plate used in a liquid crystal display device, stacked up and down at intervals in the thickness direction thereof, and randomly removing the sheet materials one by one from the cassette. Moreover, it is related with the board | plate material taking-out system which consists of a take-out apparatus which accommodates.

The plate material extraction system described above has been widely used in the industry as a temporary storage of a glass plate used in a liquid crystal display device, or as a storage between the processes in a process, a conveying means and the like in the manufacturing process of the device.

In that case, it is necessary to respond to the request that a glass plate is accommodated in a horizontal state and can be taken out at random one by one. On the other hand, from the point of increasing the size of the liquid crystal display device and improving the productivity, the vertical and horizontal dimensions of the glass plate tend to be increased, and it is also necessary to prevent the bending of the glass plate in the receiving state from being disturbed when taking out and storing the glass plate.

In order to solve these problems, various board | substrate extraction systems are proposed, and what was described in patent document 1 is the example, and the outline is shown in FIG.

The sheet material taking-out system 120 of FIG. 5 (a) has the glass plate G which is a plate material on the several support rod 116 of the several shelf-shaped board loading part 115 provided in the box-shaped cassette 112. As shown in FIG. When loading and accommodating and taking out and storing glass plate G, the slide fork (not shown) was made to move forward and backward between the some support rod 116.

However, in this system 120, it is necessary to determine the length of the supporting rod 116 in consideration of the bending of the glass plate G and the slide fork in addition to the space for allowing the slide fork to move forward and backward. Its length was long enough. Therefore, the pitch of the board | plate material loading part 115 could not be made smaller than that, and the improvement of the storage efficiency of the glass plate G to the cassette 112 was limited.

The sheet material taking-out system 130 of FIG. 5 (b) uses what is called a cassette 123 of a wire system. In the cassette 123 of this system 130, the wire 124 is pulled between the frame bodies, and functions as a shelf board | plate loading part, and the glass plate G is mounted here.

The dispensing apparatus 121 is comprised by two steps of upper and lower sides, and is provided with the upper fork 121-1 and the lower fork 121-2 which can each move forward and backward independently, and this lower fork 121-2 A large number of support rods 122 are installed in the). The upper fork 121-1 and the lower fork 121-2 do not interfere with each other in the horizontal direction, and the support rod 122 also does not interfere with the wire 124 on the cassette 123 side in the horizontal direction.

When the glass plate G is taken out by this take-out apparatus 121, only the lower fork 121-2 is inserted below the wire 124 which mounted the glass plate G first. Subsequently, the lower fork 121-2 is raised to mount the glass plate G on the support rod 122, and the glass plate G is separated from the wire 124.

Next, the upper fork 121-1 is inserted into the gap between the glass plate G and the wire 124 thus formed so as to move forward and backward.

However, in this system 130, the same deflection problem as the support rod 116 of the system 120 exists with respect to the length of the support rod 122, and the configuration of the take-out device 121 is complicated, and thus many take-out processes are performed. There was a problem of losing extra time.

EMBODIMENT OF THE INVENTION Hereinafter, although the best form for implementing this invention is demonstrated using drawing, it is not limited to the following examples at all, unless the meaning of this invention is exceeded. 1 is a perspective view showing an embodiment of a sheet taking out system of the present invention.

This sheet material taking-out system 100 temporarily stores the glass plate used for a liquid crystal display device, or is widely used for the storage, conveying means, etc. between processes in a manufacturing process of the said apparatus, and makes glass plate G the thickness direction. Retract and move the cassette 10 for horizontally accommodating and horizontally spaced apart, and the plate loading part 25 for taking out and storing the glass plate G from the cassette 10 one by one. The take-out apparatus 20 which turned and moved was provided.

The cassette 10 is a box-shaped square structure, in which the whole can be moved and transported in a state where the glass plate G is accommodated. In the cassette 10, a plurality of plate loading portions 11 having a flat plate shape are provided, and a multi-stage shelf is formed.

And the cassette 10 supports the glass plate G accommodated in the cassette 10 by the surface of the board | plate material loading part 11, and loads, and considers that the bending by the weight of the glass plate G accommodated is made small. It is. Moreover, the opening part 10a of a front surface part is formed in order to put in and take out glass plate G. As shown in FIG.

On the other hand, the plate loading part 25 provided in the take-out apparatus 20 is formed so that it may become the same plane shape as the plate loading part 11, in order to carry glass plate G horizontally. Moreover, the board | plate material loading part 25 is provided with the hand 21 which is a drawing means which hold | maintains the edge part of glass plate G, and takes out.

FIG. 2 is a diagram conceptually showing a bar of the cassette 10 shown in FIG. 1 as viewed from the take-out apparatus 20 side. On the left and right of each plate loading part 11, the air intake opening 13 which is a joint part of the air pipe 14 is formed. In each plate loading portion 11, an air pipe is enclosed in a lattice shape vertically and horizontally, and the air outlet 12 of the air is blown so that air is injected into the contact surface side with the glass plate G of each plate loading portion 11. A plurality is formed.

For this reason, when air is supplied from the air intake port 13, air is ejected from the some air outlet 12, and the glass plate G mounted on the board | plate loading part 11 is made to float.

FIG. 3 is a diagram conceptually showing a bar loading part 25 and a hand 21 of the take-out apparatus 20 viewed from the same direction as in FIG. 2. The plate loading part 25 and the hand 21 are moved by the control part of the take-out apparatus 20 so that the plate loading part 25 can raise and lower up and down and rotate left and right directions, and the It is comprised so that the hand 21 may move back and forth on the board | plate material loading part 25, and to put in and take out glass plate G by this.

The plate loading part 25 is provided with a supply port 23 for air to be connected to the inlet 13 of the cassette 10, and is connected to the inlet 13 through the air supply port 23. The supply pipe 24 is provided. In addition, a plurality of air outlets 22 for lifting the work G from the plate loading portion 25 are formed so that air is injected into the contact surface side of the plate loading portion 25 with the glass plate G. An air supply pipe 26 for supplying air to 22 is provided.

On the other hand, the hand 21 is a Bernoulli chuck using Bernoulli's principle, and sucks and holds the glass plate G in a non-contact state. Air is also enclosed inside the hand 21 of the plate loading part 25 from the air supply pipe 26, and the glass plate G is adsorbed-held in the non-contact state using air.

Here, the Bernoulli chuck using Bernoulli's principle ejects gas (mainly nitrogen gas) from the nozzle in the center of the suction plate of the hand 21, flows a high-speed gas along the surface of the glass plate G, and generates negative pressure. The chuck means that the glass plate G is kept in contact with the suction plate of the hand 21 by this negative pressure.

4 is a diagram conceptually showing a bar viewed from the side of a state in which the glass plate G is taken out and put into the cassette 10. The take-out apparatus 20 moves in front of the opening 10a of the cassette 10, and the air inlet 13 and the air supply port 23 of the air are removed from the cassette 10 of the glass plate G. In joint, the air pipe 14 and the air supply pipe 24 are connected.

For this reason, the glass plate G which is a workpiece | work is loaded from the supply port 23 of the air of the blower 20 through the blower inlet 13 of the air of the cassette 10 in the air supplied from the blower 20. It enters the board loading part 11 which is made.

At this time, since the air pipe 14 is piped longitudinally and horizontally in the plate loading portion 11, air is supplied to the whole plate loading portion 11 and exits from the outlet 12 of the plurality of air. As a result, the work G rises from the plate loading part 11.

On the other hand, air is also supplied to the hand 21 and the plate loading part 25 of the take-out apparatus 20, and the edge of the floating glass plate G is adsorbed and held by the hand 21 to hold the hand 21. The glass plate G is taken out by moving (advancing) back and forth on the plate loading part 25.

Thereby, the glass plate G is taken out by carrying out parallel movement in the horizontal direction in the non-contact state on the same plane of the board | plate material loading part 11 and the board | plate material loading part 25. FIG. In addition, storage of the glass plate G from the take-out apparatus 20 to the cassette 10 is performed by the said reverse procedure.

As mentioned above, according to the board | plate material taking-out system 100, the glass plate G is made to advance and retreat the hand 21, floating up the glass plate G from the board | plate loading part 11 with air blown out from the blower outlet 12, and supporting it from below. By holding the edge portion of), the sheet material loading portion 11 can take out and store the glass plate G randomly one by one in a non-contact state.

That is, since the whole surface of the glass plate G is supported from below by the air, the glass plate G which is taking out or storing | retaining is not cantilever support by the hand 21, but of the glass plate G and the hand 21 is not. There is no need to consider the warpage. Moreover, since the board | substrate loading part 11 is made into flat plate shape, when the blowout port 22 is removed, the problem of the bending of the glass plate G of a loading state is also small.

Since the glass plate G can be lifted out of the plate loading part 11 in this way, it is not necessary to widen the upper and lower pitches of the plate loading part 11 in consideration of the bending of the slide fork or the bending of the plate material as before. For this reason, the pitch between the plate loading parts 11 can be shortened, the storage efficiency to the cassette 10 can be improved, and the glass plate G can be horizontally stored by a smaller pitch.

In addition, since the whole surface of the glass plate G is supported from below by the air in the glass plate G which is taking out or storing, only taking out or storing by the hand 21 moves the glass plate G in a horizontal direction. It does not need to insert the hand below the glass plate G or to move it up and down, and the structure of the take-out apparatus 20 does not become complicated, there are not many processes of taking out, and it does not require extra time. .

In addition, a plurality of air outlets 22 for lifting the work G from the plate loading part 25 are formed, and an air supply pipe 26 for supplying air to the air outlet 22 is provided. Since the air is blown out from the surface of (25), the glass plate G does not contact the board loading part 25, but is smooth on the same plane of the board loading part 11 and the board loading part 25. Is loaded. Thereby, taking out or storing can be taken out without considering the degree of curvature of glass plate G at all, and glass plate G is not damaged.

In each plate loading part 11, an air inlet 13 of air is provided, and an air supply port 23 and an air supply pipe 24 connected to the air outlet 13 are connected to the blower device 20. Since it is provided, it is possible to select which plate loading portion 11 to supply the air once supplied to the cassette 10, and to supply the air supply means for supplying each plate loading portion 11 to a simple system. can do. In addition, the air supply port 23 ends in one.

Since the hand 21 adsorbs and holds the glass plate G in a non-contact state, the hand 21 does not come into contact with the glass plate G at all in this respect, and thus can be withdrawn, taken out, or stored without damaging the plate material. .

By the way, although the glass plate G tends to be enlarged in order to improve the productivity and yield of the manufacturing process, according to the combination of the cassette 10 and the take-out apparatus 20, it will become large when the size of glass plate G becomes large. The more the effect which can avoid the influence of curvature becomes larger, it is suitable for the tendency of enlargement of the glass plate for liquid crystal display devices.

As mentioned above, although the best form with respect to the cassette and the board | plate material taking-out system 100 of this invention was demonstrated based on an Example, this invention is not limited to the structure as described in the said Example, and is in the range which does not deviate from the meaning. Therefore, the structure can be changed as appropriate.

For example, the cassette and the take-out apparatus of the present invention require not only such a glass plate but also storage in a horizontal state, and can be suitably applied to a plate member having a large longitudinal dimension in comparison with the thickness thereof. As a board | plate material, glass, resin for liquid crystal panels, a plasma display panel, or an organic electroluminescent display panel is used, for example.

In addition, in the said Example, although the hand 21 which adsorbs and hold | maintains glass plate G in a non-contact state as drawing out means is illustrated, it is not limited to this at all. That is, the drawing means may be taken out by holding the edge of the floating plate, and may be, for example, by holding the edge of the glass plate G directly.

According to the cassette according to claim 1, since the air outlet port for lifting the workpiece from the plate loading portion is formed in the plate loading portion accommodating the plurality of plate materials, the plate is lifted from the plate loading portion by air to support it from below. The board can be taken out and stored at random one by one. In addition, since the plate loading part can be made into a flat plate shape by removing the outlet, the problem of bending of the plate is also less. Therefore, the pitch between the plate loading parts can be shortened, and the storage efficiency in the cassette can be improved.

According to the sheet material taking-out system of Claim 2, it consists of a cassette which accommodates a several board | plate material, and the take-out apparatus which takes out a board | plate material one by one from this cassette, Comprising: From the said board | plate loading part to the said board | plate and the plate | board loading part of the said take-out apparatus. Since an air outlet for lifting the work is formed and a take-out means for holding and taking out the edge of the floating plate is installed in the take-out device, the edge of the plate is supported while the plate is lifted from the plate-loading portion by air to support it from below. The sheet material can be moved in the horizontal direction by the drawing means for retaining the portion, and the sheet material can be randomly taken out and stored one by one. For this reason, since it is not a cantilever support, it is not necessary to consider the bending of a board | plate material and a take-out means, and since a board | plate loading part can be made into a flat plate shape by removing a ejection opening, the problem of a board | plate bending is also small. Therefore, the pitch between the plate loading portions can be shortened, and the storage efficiency in the cassette can be improved.

According to the sheet taking-out system of Claim 3, in addition to the effect which the sheet | seat taking-out system of Claim 2 shows, while forming an air inlet of each board | plate loading part of a cassette, it connects to a blower inlet, Since the air supply pipe is provided, it is not necessary to provide the air supply means for each plate loading part, and the effect can be made into a simple system.

According to the sheet taking-out system according to claim 4, in addition to the effect exhibited by the sheet taking-out system according to claim 2, the drawing means adsorbs and holds the plate in a non-contact state, so that the sheet taking-out, take-out and storage can be carried out without damaging the plate.
