Description

  The present invention relates to a sheet glass article separating apparatus, and more specifically, a technology for conveying a sheet glass article after being cut or a sheet glass article in which a plurality of sheets are arranged close to each other in parallel while being separated from each other. About.

  Plate glass used for flat panel displays such as plasma displays and liquid crystal displays, and window glass for buildings, etc., cut out small area plate glass from large area plate glass in the manufacturing process, and trimmed edges along the side of the plate glass The glass sheet may be cut off.

  As a method for cutting the plate glass, the scribe line is formed by pressing the plate glass using a folding member after forming the scribe line on the plate glass as in the techniques disclosed in Patent Documents 1 to 3 described below. Generally, a method of giving a bending moment to the peripheral portion of the glass plate and cutting the plate glass along the scribe line is widely used.

  However, when the cutting method as described above is used, after the split member presses and cuts the plate glass, the cut surfaces of the plate glass come into contact with each other, and scratches, cracks, etc. occur on each cut surface. Therefore, there is a problem that the quality of the plate glass is deteriorated. In order to prevent such a problem, it was necessary to separate the glass plates immediately after cutting from each other to prevent contact between the cut surfaces.

  In order to prevent the contact between the cut surfaces of each sheet glass after cutting, the following Patent Document 4 adsorbs the sheet glass to both sides of the scribe line formed on the sheet glass. A table that can be held is provided, and after the glass plate is sucked and held on the above table, one table is rotated to give a bending moment to the periphery of the scribe line, cutting the glass plate and cutting surfaces to each other. A technique that can be separated to prevent contact between cut surfaces is disclosed.

  In Patent Document 5, as a technique for preventing contact between cut surfaces of each plate glass after cutting, one side of the plate glass on which a scribe line is formed is sandwiched from above and below by a sandwiching member, and then the sandwiching member is rotated. A technique is disclosed in which, by moving, a bending moment is applied to the peripheral portion of the scribe line, the plate glass is cut, the cut surfaces are separated from each other, and contact between the cut surfaces can be prevented.

JP 2004-051394 A JP-A-61-168547 JP 2006-315901 A Japanese Patent No. 3031384 Japanese Patent Publication No. 7-51453

  However, in the techniques disclosed in Patent Documents 4 and 5 above, the cutting surfaces of the plate glass can be separated from each other, but the cutting device is used every time the plate glass supplied to the device is cut. Thus, it is necessary to transfer the cut sheet glass to another place.

  Therefore, the loading of the plate glass to the cutting position and the unloading of the plate glass after cutting cannot be performed as a continuous process or a series of processes, and in the case of cutting a large amount of plate glass continuously, There was a problem that work efficiency was likely to deteriorate.

  Such a problem does not occur only when cutting the plate glass using the split member. For example, the plate glass is formed by irradiating the plate glass with a laser and jetting a refrigerant following the laser. By generating thermal stress around the initial crack and developing the initial crack, laser cutting that cuts the glass sheet or laser melting that cuts the glass sheet by removing the molten glass melted in the laser irradiation part. The same thing happens.

  Furthermore, the problem of separation of such plate glass is not limited to after the cutting of the plate glass, when it is necessary to perform a manufacturing-related process by arranging a plurality of plate glasses already in parallel without cutting, When bringing the plurality of plate glasses into and out of the processing position, there is a problem of how to optimize the reduction of the quality of the plate glass and improving the working efficiency.

  In addition to plate glass, a glass laminate including plate glass as a constituent element, a glass resin laminate in which plate glass and a resin sheet are laminated, a liquid crystal panel, etc. (hereinafter referred to as plate glass and these are collectively referred to as plate glass articles) The same problem occurs when manufacturing-related processing is performed by cutting or arranging them in close proximity.

  In view of the above circumstances, the problem of the present invention is that it is possible to suppress a reduction in the quality of the plate glass article in the cutting and separating step of the plate glass article, or in the separation step of separating a plurality of plate glass articles arranged close to each other in parallel, and It is an object of the present invention to provide a sheet glass article separation device capable of improving working efficiency.

In order to solve the problem at the time of cutting of a sheet glass article, the present invention cuts the sheet glass article along a planned cutting line extending in the conveying direction at the cutting position and transports the sheet glass article to the cutting position. and a separation device configured glass sheet article to convey each other to separate the sheet glass article, while the plate glass article is arranged in parallel to a boundary of the cutting line when in the cutting position In the conveyance area on the side and the other side, conveying means for conveying the sheet glass article before cutting and the sheet glass article after cutting from the upstream side to the downstream side are installed, respectively, and at least one existing in the conveyance area on the one side said conveying means, and at least one said carrier means consists in the transfer area of the other side, our in a direction perpendicular to the direction toward the downstream side from the upstream side Characterized in that configured to approach and away Te. Here, the above "approach and separation" is not only the case where the two corresponding conveying means both move and both approach and separate, but only one of the conveying means does not move and the other conveying means does not move. Not only when one of the transport means moves relative to the other transport means in parallel, but also the gap between the two moves from the upstream side to the downstream side. This includes the case of relative movement so that it gradually expands as it goes on (hereinafter the same). Further, the “sheet glass article” includes not only the sheet glass but also a sheet glass such as a glass laminated body, a glass resin laminated body, and a liquid crystal panel (hereinafter the same).

  According to such a configuration, the plate glass article carried into the sheet glass article separation device is cut at the cutting position, and each plate glass article after the cutting is at least one conveying means existing in the conveyance area on one side. Are separated from each other by separating the at least one conveying means in the conveying area on the other side. Therefore, if the conveying means is separated immediately after the sheet glass article is cut, each sheet glass article after cutting is not separated from the cutting position by the conveying means without causing contact between the cut surfaces. It is maintained and conveyed downstream. On the other hand, when the transporting means once separated is approached and returned to the initial position, the subsequent new sheet glass article is carried into the sheet glass article separation device and then the same as described above. , Cut and separated, and conveyed downstream from the cutting position. By repeating the above operation, a series of continuous operations for separating the sheet glass article into the sheet glass article and then into the cutting position, and bringing the sheet glass article into the sheet glass article from the cutting position. It can be done as a process. As a result, it is possible to improve work efficiency in the cutting process while preventing deterioration of the quality of the sheet glass article due to contact between the cut surfaces of the cut sheet glass article. In addition, when a plate glass article is cut | disconnected in a cutting position, it is preferable that the conveyance operation of the plate glass article by a conveyance means is stopped.

  In the above configuration, a plurality of transport means are installed in parallel in at least one transport area of the transport areas on the one side and the other side, and at least one of the transport means is in the approach and separation state. The movable conveying means and at least one other conveying means out of the plurality of conveying means are capable of adsorbing and releasing the sheet glass article. Is preferred.

  In this way, the sheet glass article carried into the sheet glass article separation device is preferably stopped and cut at the cutting position, and the sheet glass article after the cutting is subjected to the following processing. In other words, on at least one side of the both-side conveyance area with the planned cutting line as a boundary, a conveyance means other than the movable conveyance means, that is, an immovable conveyance means (hereinafter referred to as a fixed-side conveyance means) Under the state where the suction is released, a movable conveying means (hereinafter referred to as a movable-side conveying means) moves in a direction to separate the glass sheet articles after cutting while adsorbing and conveying the glass sheet articles. (Separate). Also in this case, if the movable-side conveying means is moved away immediately after cutting the plate glass article, the respective plate glass articles after cutting are separated without causing contact between the cut surfaces. Then, after the mutual separation of the cut sheet glass articles is completed, the fixed-side conveying means sucks and conveys the cut sheet glass article, and the movable-side conveying means releases the adsorption to the cut sheet glass article. In this state, return to the original position (approach movement). That is, since the movable-side conveyance unit is released from the adsorption to the plate glass article, the movable-side conveyance unit can return to the original position without obstructing the conveyance of the plate glass article by the fixed-side conveyance unit. Therefore, while the movable-side transport unit is returning to the original position, the fixed-side transport unit can carry in a subsequent new glass sheet article. Thereby, since separation of each sheet glass article after cutting and unloading from the cutting position to the downstream side and carrying in of the subsequent new sheet glass article to the cutting position can be performed continuously, the cutting step It is possible to further improve the work efficiency.

  Said structure WHEREIN: It is preferable to interpose a protective sheet between all the said conveyance means and the said plate glass goods.

  In this way, the movable-side conveying means is cut when the movable-side conveying means moves (separates) in the direction of separating the cut-out glass sheets while sucking and conveying the cut-out glass sheets. The sheet glass is caused by sliding between the sheet glass article and the conveying means when returning to the original position (approaching movement) before the cut sheet glass article is separated in a state where the adsorption to the sheet glass article is released. It is possible to reduce the risk of scratches on the lower surface of the article.

  Said structure WHEREIN: It is preferable to comprise so that gas may be ejected with respect to the said plate glass goods at the time of cancellation | release of the adsorption | suction with respect to the said plate glass goods.

  In this way, by ejecting gas from the conveying means in a state where the adsorption to the sheet glass article is released to the sheet glass article, the plate glass article is in a floating state on the conveying means ejecting the gas, Since it is possible to reduce the risk of sliding with the glass sheet article as much as possible, it is possible to more effectively suppress the occurrence of scratches on the lower surface of the glass sheet article.

  Said structure WHEREIN: It is preferable that the said conveying means made movable is installed in the sequence direction outermost position of these several conveying means.

  In this way, the movable range of the movable side conveying means can be increased compared to the case where the movable side conveying means is installed between the plurality of fixed side conveying means. It becomes possible to separate the made sheet glass article over a longer distance. Further, when separating the sheet glass articles from each other, the protective sheet interposed between the conveying means and the sheet glass article is not easily bent due to the absence of the fixed-side conveying means in front of the moving direction of the movable conveying means. . As a result, it becomes difficult to peel the plate glass article from the protective sheet by sticking the bent protective sheet into the end face or edge of the cut sheet glass article, and it becomes difficult to control the conveyance / stop position of the plate glass article. Problems can be prevented.

  In the above configuration, even if the plurality of transfer means including the movable transfer means are installed in the transfer area on the one side, and all the transfer means installed in the transfer area on the other side are immovable. Good.

  In this way, the structure of the transport area on the side where the movable transport means is not provided can be simplified, and the manufacturing cost of the apparatus can be reduced.

Further, in order to solve the problem in the case where manufacturing-related processing is performed on a plurality of plate glass articles arranged in parallel, the present invention brings a plurality of plate glass articles arranged in parallel to each other with their opposing end surfaces close to each other. A plurality of sheet glass articles that have been subjected to manufacturing-related processing such as surface coating processing, cleaning processing, packing processing, or inspection processing , and subjected to the manufacturing-related processing. A sheet glass article separating apparatus configured to separate and convey each opposed end face by separating each opposed end face, and a boundary between each opposed end face when the plurality of sheet glass articles are present at the processing position and to the plurality of transfer areas arranged in parallel, the conveyance of one arranged between opposing end surfaces of adjacent glass sheet article in parallel with the boundary side and the other side territory In the manufacturing-related pretreatment of the plate glass article and the plate glass article after the manufacture-related processing from the upstream side of the conveying means for conveying to the downstream side respectively installed, at least one existing in the transport region of the one side It said conveying means, at least one said carrier means consists in the transfer area of the other side, characterized in that configured to close and away in the direction orthogonal to the direction toward the downstream side from the upstream side. Here, the above "proximity" means that the gap between the opposing end surfaces of adjacent sheet glass articles is 3000 mm or less (preferably 300 mm or less), and the gap may be zero or substantially zero. .

  According to such a configuration, the sheet glass article is carried in a state in which a plurality of sheet glass articles are arranged close to each other at the processing position by the sheet glass article separation device, and the manufacturing related process is performed, and each sheet glass article after the processing is performed. (Hereinafter referred to as a processed sheet glass article) is composed of at least one transfer means existing in one transfer area and the other transfer area in two transfer areas having a boundary between opposing end surfaces of adjacent processed sheet glass articles. Are separated from each other by being separated from at least one of the conveying means. Accordingly, if the transport means is separated immediately after the manufacturing-related process is performed on the sheet glass article, each processed sheet glass article is separated from the processing position by the transport means without the opposing end surfaces being close to each other. The transported state is maintained downstream. On the other hand, when the transporting means once separated is approached and returned to the original position, the subsequent plurality of sheet glass articles are carried into the processing position by the sheet glass article separation device, and then In the same manner as in the case of (2), they are processed, separated from each other, and conveyed downstream from the processing position. By repeating the above operation, the sheet glass article separating apparatus, and hence the loading of the sheet glass article into the processing position, and the sheet glass article separating apparatus, and then the removal of each processed sheet glass article from the processing position are continuous. It can be performed as a series of processes. As a result, it is possible to improve work efficiency in the processing step while preventing deterioration in the quality of the sheet glass article due to the proximity of the opposed end surfaces of the plurality of processed sheet glass articles that have undergone manufacturing-related processing. . In addition, when the manufacturing related process is performed on the sheet glass article at the processing position, it is preferable that the conveying operation of the sheet glass article by the conveying unit is stopped.

  In the above configuration, a plurality of transport means are installed in parallel in all of the plurality of transport areas or in all remaining transport areas excluding one transport area from the plurality of transport areas, and at least one of them. A conveying means is movable for the approach and separation, and among the plurality of conveying means, the movable conveying means and at least one conveying means other than the movable conveying means are It is preferable to be able to adsorb and release the sheet glass article.

  In this way, the sheet glass article carried into the processing position of the sheet glass article separation device is preferably stopped and processed at the processing position, and the sheet glass article after the processing is as shown below. Get treatment. That is, in at least one side of two conveyance regions having a boundary between opposing end surfaces of adjacent processed glass sheet articles, a conveyance unit other than a movable conveyance unit, that is, a non-movable conveyance unit (hereinafter referred to as a fixed-side conveyance unit). However, in a state in which the adsorption to the processed sheet glass article is released, a movable conveying means (hereinafter referred to as a movable-side conveying means) adsorbs and conveys the processed glass sheet article while mutually handling each processed glass sheet article. Move (separate) in the direction of separation. Also in this case, if the movable-side conveying means is moved away immediately after the manufacturing-related process is performed on the plate glass article, the opposed end surfaces of the processed plate glass articles are separated from each other without being close to each other. And after mutual separation of a processed plate glass article is completed, while a fixed side conveyance means adsorbs and conveys a processed plate glass article, a movable side conveyance means has canceled adsorption to a processed plate glass article. Return to the original position (approach). Therefore, while the movable-side conveyance means is returning to the original position, the fixed-side conveyance means can carry in a new subsequent plurality of sheet glass articles. Thereby, the separation of the processed sheet glass articles and the unloading from the processing position to the downstream side and the subsequent loading of a plurality of new sheet glass articles to the processing position are simultaneously performed by the same plurality of conveying means. Therefore, it is possible to further improve the work efficiency in the manufacturing related process.

  In the above-described configuration, a protective sheet may be interposed between the plurality of conveyance units installed in all the remaining conveyance areas excluding one conveyance area from the plurality of conveyance areas, and the sheet glass article. preferable.

First, a sheet glass article separating apparatus according to a first embodiment of the present invention will be described with reference to FIGS. In the first embodiment, a case where a bending moment is applied to the periphery of a scribe line formed along a planned cutting line by a folding member to cut a plate glass as a plate glass article will be described as an example.

  In this embodiment, a conveyor is used as a conveying means for conveying the plate glass (details will be described later). As shown in FIGS. 1 and 2, on the upstream side of the sheet glass article separation device 1, there is a carry-in conveyor S for carrying plate glass G as a sheet glass article into the sheet glass article separation device 1, and on the downstream side, sheet glass. A carry-out conveyor R for carrying out the both glass sheets G1 and G2 cut and separated by the article separation device 1 is provided. The conveyor belt V provided to each of the conveyor, the carry-in conveyor S, and the carry-out conveyor R of the sheet glass article separating apparatus 1 is driven as the pulley 20 is rotated by a power source such as a motor (not shown). It is a mechanism.

  Specifically, as shown in FIG. 1, the sheet glass article separating apparatus 1 includes a movable-side conveyor 10 and a fixed-side conveyor 11a (a cutting line to be cut) that conveys the sheet glass G and the cut two sheet glasses G1 and G2 in the C direction. Among the two-sided conveyance areas defined as boundaries, the fixed-side conveyor of the conveyance area including the movable-side conveyor 10), the fixed-side conveyor 11b (the conveyance areas not including the movable-side conveyor 10 among the two-sided conveyance areas whose boundary is the planned cutting line) (Fixed side conveyors) are arranged in parallel to each other. Power is transmitted to the movable conveyor 10 by a ball screw mechanism or the like (not shown), and the movable conveyor 10 can be moved forward and backward between the reference position P1 and the retracted position P2 in the width direction orthogonal to the sheet glass conveyance direction C. On the other hand, both the fixed side conveyors 11a and 11b are fixedly installed at the reference position. Further, the glass sheet is adsorbed or floated on the mounting surface (surface of the conveyor belt V) on which the plate glass G of the movable conveyor 10 and the fixed conveyors 11a and 11b and the cut glass plates G1 and G2 are cut. A large number of ventilation holes H are provided, and gas can be sucked and ejected through the ventilation holes H by a gas supply / discharge source (not shown).

  In addition, although the separation apparatus 1 of plate glass goods is comprised by the one movable side conveyor 10, the one fixed side conveyor 11a, and the two fixed side conveyors 11b, it is the plate glass article of this invention. The configuration of the separation device 1 is not limited to this, and the number of the movable conveyor 10 and the fixed conveyors 11a and 11b may be increased or decreased as appropriate. Moreover, the movable conveyor 10 does not necessarily need to be installed on the outer side of the fixed conveyor 11a, and may be provided between two or more fixed conveyors 11a. Further, the suction and ejection of gas in the movable conveyor 10 may be controlled separately from the two fixed conveyors 11a and 11b.

  Between the both fixed side conveyors 11a and 11b adjacent in the center in the width direction of the sheet glass article separating apparatus 1, a folding member 30 for pressing and cutting the sheet glass G from the back surface side (lower surface side); A cutting member 40 having a cutting blade that advances from the folding member 30 and cuts the protective sheet 50 (details of the protective sheet will be described later) is provided. In addition, as a raw material of the front-end | tip part (upper end part) in the folding member 30, PVC resin etc. can be used. Further, the installation position of the split member 30 is not limited to the position shown in FIG. 1, so that the cut glass sheets G 1 and G 2 are asymmetric in the width direction with respect to the split member 30. May be installed. In other words, the split member 30 may be installed so that the size of the two sheet glasses G1 and G2 after cutting can be different.

  As shown in FIG. 1 and FIG. 2, the sheet glass G carried into the sheet glass article separation device 1 from the carry-in side conveyor S and the cut both sheet glass carried out from the sheet glass article separation device 1 to the carry-out side conveyor R Between G1 and G2 and the conveyor belt V, the protective sheet 50 which protects plate glass is interposed. Here, as the protective sheet 50, a film or sheet of paper (corrugated cardboard), cloth, wood, cellophane, glass, synthetic resin (polyethylene, nylon, foamed urethane, rubber, etc.), or a film or What was processed into the sheet form can be used. Moreover, even if it is not what was enumerated above, if it is based on these, it can be used as the protection sheet 50. In addition, it is preferable that the protective sheet 50 has air permeability.

  As shown in FIG. 3, the split member 30 is roughly divided into a tip portion 31 and a base portion 32, and the tip portion 31 is configured by a pair of divided bodies 31 a having a gap Z between the opposing end surfaces. ing. The front end surfaces of the pair of divided bodies 31a are inclined planes that are inclined downward as they move outward in the width direction. Moreover, the base 32 is comprised by a pair of support board material 32a each fixed using the volt | bolt 35 under the pair of division body 31a. The folding member 30 is configured to move up and down by a lifting / lowering drive means such as a ball screw mechanism and a fluid pressure cylinder (not shown) connected to the lower portions of the pair of support plate members 32a.

  A cutting member 40 for cutting the protective sheet 50 is interposed inside the base portion 32 of the folding member 30. The cutting member 40 has a cutting blade 40a located at the uppermost part and a holding body 40b that holds the cutting blade 40a from below, and the cutting blade 40a is fixed to the upper part of the holding body 40b with a bolt 36. ing. Further, the cutting member 40 is configured to move up and down by a lifting / lowering driving means such as a ball screw mechanism or a fluid pressure cylinder (not shown). And when this cutting member 40 moves up, it is set as the structure which the cutting blade 40a protrudes from the front-end | tip of both the division bodies 31a through the clearance gap Z of the both division bodies 31a of the folding member 30. FIG.

  Note that the folding member 30 and the cutting member 40 are not limited to the configuration shown in FIG. 3, and may be configured as shown in FIGS. 4a and 4b, for example. That is, in the folding member 30 shown in these drawings, both opposing end surfaces of the pair of divided bodies 30b constituting the tip portion 31 can be joined and separated. The tip surfaces of the pair of divided bodies 30b are convex curved surfaces (in the example shown, a substantially semicircular cross section). And this pair of division body 30b is comprised so that it may separate with respect to the spring force while joining with the spring force of the compression spring 39 each incorporated in each division body 30b. Further, the pair of support plate members 30 a constituting the base portion 32 are connected and integrated through a connecting portion W. On the other hand, the cutting member 40 has a long hole 38 having a predetermined length in the vertical direction, and the connecting portion W of the support plate member 30a is loosely inserted into the long hole 38. Therefore, when the cutting member 40 is located at the lower end, as shown in FIG. 4a, the two split bodies 30b of the folding member 30 are joined by the spring force of the compression spring 39, and the cutting member 40 is moved upward. In this case, as shown in FIG. 4b, the two divided bodies 30b are pushed apart by the cutting member 40 against the spring force of the compression spring 39, and the cutting blade provided at the tip of the cutting member 40 is the tip of the two divided bodies 30b. It is set as the structure which protrudes from.

  Next, the function and effect of the sheet glass article separation device 1 according to the first embodiment of the present invention will be described with reference to FIG. In FIG. 5, the arrows attached to the movable conveyor 10 and the fixed conveyors 11a and 11b indicate gas suction or jetting, the downward arrow X indicates gas suction, and the upward arrow Y Indicates gas ejection.

  When the plate glass G placed on the protective sheet 50 is carried into the sheet glass article separating device 1 from the carry-in side conveyor S shown in FIGS. 1 and 2, as shown in FIG. And both the fixed side conveyors 11a and 11b convey the plate glass G through the air holes H in the direction C shown in FIGS. 1 and 2 (from the front side to the back side in FIG. 5). The sheet glass G to be transported stops at a predetermined cutting position with respect to the transport direction.

  After that, the sheet glass G adsorbed by the movable conveyor 10 and the two fixed conveyors 11a and 11b is raised by the folding member 30 and pressed by the raised folding member 30 as shown in FIG. 5 (b). Thus, a bending moment is applied around a scribe line (not shown), and tensile stress acts to cut the glass sheet G1 and G2. Here, it is preferable that a dust collector for sucking glass pieces discharged as chips is provided above the cut surface of the plate glass. At this time, the cutting blade 40 a of the cutting member 40 shown in FIG. 3 is retracted downward from the front end surfaces of the two split bodies 31 a of the folding member 30.

  Immediately after the sheet glass G is cut, both opposing end portions of both the sheet glasses G1 and G2 cut as shown in FIG. 5C are arranged at the front ends 31 (both divided parts) of the folding member 30 shown in FIG. The tip end surface of the body 31a is supported and lifted, and a gap is generated between the opposed end surfaces of the cut glass plates G1 and G2. When the cutting blade 40a advances into this gap, the protective sheet 50 is cut.

  After the protective sheet 50 is cut, an area for conveying the cut glass sheet G2 as shown in FIG. 5D (hereinafter referred to as a left-side conveyance area in the left area with reference to the folding member 30 in FIG. 5). ), The two fixed-side conveyors 11b convey the sheet glass G2 in the direction C shown in FIGS. 1 and 2 while adsorbing the sheet glass G2 in the same manner as before the cutting of the sheet glass G.

  On the other hand, in the area for conveying the cut sheet glass G1 (in the right area with reference to the split member 30 in FIG. 5, hereinafter referred to as the right conveyance area), the movable conveyor 10 adsorbs the sheet glass G1, 1 and FIG. 2 and conveyed in the direction C, as shown in FIG. 5 (d), both glass sheets G1 cut by starting movement in the direction of arrow a from the reference position P1 toward the retracted position P2, Start separation of G2.

  Further, when the movable-side conveyor 10 adsorbs the plate glass G1, the fixed-side conveyor 11a in the right conveyance area releases the adsorption to the plate glass G1 and ejects gas toward the plate glass G1 from the vent hole H, thereby causing the plate glass G1. Is floated on the fixed conveyor 11a.

  As a result, contact between the cut surfaces of the both glass sheets G1 and G2 can be effectively prevented, and it is possible to suppress deterioration of the quality of the glass sheets, and simultaneously transport the cut glass sheets G1 and G2. Work efficiency can be improved.

  Here, the movable conveyor 10 is provided so as to be located on the outermost side of the fixed conveyor 11a, compared to the case where the movable conveyor 10 is installed between the adjacent fixed conveyors 11a, Since the movable range (distance between the reference position P1 and the retracted position P2) of the movable conveyor 10 can be increased, the cut two glass sheets G1 and G2 can be separated over a longer distance. . Further, when the plate glasses are separated from each other, there is no fixed side conveyor 11a in front of the movable side conveyor 10 in the moving direction, so that the protection interposed between the plate glass and the movable side conveyor 10 and the fixed side conveyor 11a. Since the sheet 50 becomes difficult to bend, it becomes difficult to peel off the plate glass and the protective sheet by sticking the end face or edge of the cut plate glass, and it is difficult to control the conveyance / stop position of the plate glass. It becomes possible to prevent the problem of becoming.

  As shown in FIG. 5 (d), when the movable conveyor 10 moves while adsorbing the sheet glass G1 in the direction of arrow a and arrives at the retracted position P2 as shown in FIG. 5 (e), the sheet glass G1 is reached at this point. Is separated from the glass sheet G2. Then, the movable conveyor 10 that has arrived at the retreat position P2 releases the adsorption of the plate glass G1 and causes the gas to blow out from the vent hole H toward the plate glass G1, thereby floating the plate glass G1 on the movable conveyor 10. At the same time, the movement starts from the retracted position P2 toward the reference position P1 in the direction of the arrow b shown in FIG.

  On the other hand, when the movable conveyor 10 arrives at the retracted position P2 and cancels the adsorption of the plate glass G1, the fixed-side conveyor 11a stops ejecting gas to the plate glass G1, and adsorbs the plate glass G1, while FIG. Transport in the C direction shown in FIG. (The sheet glass G1, G2 is conveyed while keeping the separation distance constant.)

  In the state shown in FIG. 5 (f), the fixed conveyors 11a and 11b in the left conveyance area and the right conveyance area respectively carry out the cut glass sheets G1 and G2 to the carry-out conveyor R, respectively. A new plate glass G to be cut is attracted and carried from the carry-in conveyor S, and is conveyed toward the cutting position in the direction C shown in FIGS.

  As shown in FIG. 5G, when the movable conveyor 10 returns to the reference position P1 while ejecting gas toward the glass sheet G1, the movable conveyor 10 stops the gas ejection, and the left conveyance area and the right conveyance. Together with the two fixed-side conveyors 11a and 11b in the region, the new sheet glass G to be cut is adsorbed and conveyed to the cutting position.

  And as shown in FIG.5 (h), when the new plate glass G conveyed to the movable side conveyor 10 and both the fixed side conveyors 11a and 11b stops in a predetermined cutting position, it will prepare for cutting the new plate glass G. Is ready.

  As described above, the sheet glass article separation device 1 repeatedly performs the operations shown in FIGS. 5A to 5H, so that both the cut glass sheets G <b> 1 and G <b> 2 are carried out to the carry-out conveyor R and carried in. Since it is possible to simultaneously and continuously carry in a new plate glass G from the side conveyor S, it is possible to improve work efficiency. Moreover, since the contact between the cut surfaces of both the cut glass plates G1 and G2 can be prevented, the quality deterioration of the plate glass can be effectively suppressed.

  In addition, in this embodiment, conveyance to the cutting position of the new plate glass G carried in from the carrying-in side conveyor S to the sheet glass article separation apparatus 1 is both the movable side conveyor 10 and the fixed side conveyors 11a and 11b. However, it may be configured to be performed only by the both fixed side conveyors 11a and 11b. In this case, when the movable conveyor 10 is returned from the retracted position P2 to the reference position P1, the movable conveyor 10 only has to be cut before the new sheet glass G carried into the sheet glass article separator 1 from the carry-in conveyor S is cut. The timing for returning to the reference position P1 is not questioned.

  Next, a sheet glass article separation device according to a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, thermal stress is generated in the plate glass by irradiation of the laser along the planned cutting line and injection of the refrigerant following the laser, and is formed at the end in the conveying direction of the plate glass. The case where a plate glass is cut | disconnected by advancing the made initial stage crack is mentioned as an example, and is demonstrated.
