Description

  The present invention relates to a glass plate conveying apparatus that suspends and supports a vertically oriented glass plate and conveys the glass plate in a lateral direction along the surface of the glass plate, and a glass plate conveying method.

  As is well known, when manufacturing a glass plate, manufacturing-related processing such as processing and inspection is performed on the manufactured glass plate. For example, processing for providing scribe lines for cutting both ends of a glass plate conveyed in a vertical posture, folding processing of glass plates along the scribe lines, inspection of manufactured glass plates, etc. Done.

  When supporting a glass plate in a vertical posture and transporting it in the lateral direction along the surface of the glass plate, the glass plate may swing in the thickness direction due to the influence of air resistance during transport. . When the glass plate swings, there is a possibility that the glass plate is damaged due to contact with members arranged around the conveyance path, or that the glass plate support portion is cracked by applying a large load.

  Therefore, in order to prevent swinging when the glass plate is conveyed in a vertical posture, a holding device that holds the vicinity of the upper and lower ends of the two sides of the glass plate (Patent Document 1) and the upper side of the glass plate are held. And the holding | grip instrument for a transfer (patent document 2) etc. with which the plate-shaped control part which controls the shaking of the glass plate to be transferred are arrange | positioned in the surface vicinity of a glass plate are known.

  However, in the gripping device described in the above-mentioned Patent Document 1, in order to grip a plurality of locations on the two sides of the glass plate to be transported, it takes time to mount the gripping member, and because the gripping member is mounted, There is a problem that the side of the glass plate cannot be processed. On the other hand, in the gripping tool described in Patent Document 2, there is a risk that the restricting portion comes into contact with the surface of the glass plate, which may cause scratches, which may reduce the quality of the glass plate as a product.

  Then, the conveyance apparatus (patent document 3) which suspends and supports a glass plate and supports the lower end of a glass plate from both surfaces non-contacting with a fluid is proposed.

JP 2002-284477 A JP 2006-056610 A JP 2010-126319 A

  By the way, in the conveyance apparatus of patent document 3, by ejecting a fluid perpendicularly | vertically with respect to the front and back of the lower part of the suspended glass plate and generating a static pressure, by supporting a glass plate non-contactingly Prevent rocking. However, in order to suppress the oscillation of the glass plate with a static pressure, it is necessary to continue to eject the fluid strongly toward the glass plate. Therefore, it is necessary to eject a fluid over the whole conveyance path of a glass plate, or to move an ejection location with the position of the glass plate conveyed. Therefore, since the control becomes complicated and the apparatus becomes large, it is not practical.

  In recent years, glass plates used in many fields have been promoted to be thin, and in order to shorten the processing time of the glass plates, it is required to increase the conveyance speed. However, when a thin glass plate is conveyed at a high speed, the glass plate swings due to air resistance. Therefore, under such conditions, simply applying a static pressure to the lower part of the glass plate as in the conveying device according to Patent Document 3 cannot effectively prevent the glass plate from swinging, and the glass plate is damaged. There is a fear.

  In the present invention made in view of the above circumstances, when a glass plate in a vertical posture is suspended and supported, even if it is a high-speed conveyance of a thin glass plate, the glass plate can be swung during conveyance. The technical challenge is to prevent it reliably.

  In order to solve the above problems, a glass plate conveying device according to the present invention is a glass plate conveying device that suspends and supports a vertical glass plate and conveys the glass plate in a lateral direction along the surface of the glass plate. An airflow generating means for generating an airflow in the transport direction of the glass plate is provided on the transport path.

  According to such a configuration, the air around the glass plate can be moved together with the glass plate by generating an air flow in the glass plate transfer direction on the glass plate transfer path. It is possible to reduce the air resistance at the time of conveyance. Therefore, it is possible to reliably prevent the glass plate from swinging during conveyance.

  In addition, a plurality of storage chambers capable of storing glass plates may be provided along the transport path, and the airflow generation means may include a pressure adjusting unit that forms a pressure difference in the plurality of storage chambers. Thereby, at the time of conveyance of a glass plate, an atmospheric pressure difference is formed between adjacent storage chambers, and an air flow can be generated by the atmospheric pressure difference. In this case, the pressure in the storage chamber on the upstream side in the transport direction is set to be relatively higher than the pressure in the storage chamber on the downstream side in the transport direction. Note that a pressure difference may be formed only by adjusting the pressure in one of the storage chambers.

  At this time, it is preferable that a pressure adjustment part adjusts the atmospheric | air pressure of a storage chamber to a positive pressure. Accordingly, since the storage chamber has a higher pressure than the environment outside the storage chamber, it is possible to prevent dust and the like from being sucked into the storage chamber from around when the airflow is generated, and the storage chamber can be kept clean.

  Furthermore, the pressure adjusting unit may have a door that opens and closes the communicating part of the adjacent storage chamber. Thereby, a pressure difference can be formed in the adjacent storage chamber by closing the door, and an air flow can be generated in the communicating portion by opening the door. In this way, an air pressure difference can be formed and an air flow can be generated easily and reliably.

  Further, the pressure adjustment unit may include an air supply unit that supplies air to the inside of the storage chamber and an exhaust unit that discharges air to the outside of the storage chamber. Thereby, the atmospheric pressure in the accommodation chamber can be easily adjusted by controlling the ratio between the air supply amount and the exhaust amount.

  At this time, it is preferable to provide an air supply part in the upper part of the accommodating part and to provide an exhaust part in the lower part of the accommodating part. Thereby, a downward air flow can be formed in the housing portion, and dust and the like in the housing portion can be effectively removed. At this time, since the air pressure in the accommodation chamber can be adjusted by controlling the air supply amount and the exhaust amount, it is possible to simultaneously remove dust and the pressure in the accommodation chamber.

  In addition, the airflow generation means may include a pair of rectifying plates disposed in proximity to positions facing the front and back surfaces of the glass plate in the accommodation chamber. Thus, when the glass plate is transported, an air flow is generated between the pair of rectifying plates, whereby an air flow can be efficiently generated around the glass plate, and the air flow generating means can be saved.

  Moreover, in order to solve the above-mentioned problem, the glass plate transport device according to the present invention is a glass plate transport method for supporting a glass plate in a vertical position by hanging and transporting it in a lateral direction along the surface of the glass plate, The glass plate is conveyed while generating an air flow in the conveyance direction of the glass plate on the conveyance path of the glass plate.

  According to such a method, the air current can be generated around the glass plate by generating the air current in the glass plate transport direction on the glass plate transport path, as described above. The causative air resistance can be reduced. Therefore, the glass plate can be prevented from swinging when the glass plate is conveyed.

  As described above, according to the present invention, when a glass plate in a vertical posture is suspended and supported, even when a thin glass plate is conveyed at high speed, the glass plate swings during conveyance. Can be reliably prevented.

The endless chain can be connected to the connecting member 25 of the support means 22 and moves the support means 22 along the moving rail 21 by driving of the drive motor. The drive motor can be driven intermittently.

  Furthermore, the airflow generation means 30 generates an airflow in the conveying direction of the glass plate G, and an air supply unit 31 that supplies air to each storage chamber 18 and an exhaust unit 41 that exhausts air from each storage chamber 18. And have. Here, as will be described later, the air pressure in each storage chamber 18 can be adjusted by adjusting the amount of air supplied to each storage chamber 18 and the amount of exhaust to be exhausted. And the exhaust part 41 comprises a pressure adjustment part. In the present embodiment, an air supply unit 31 and an exhaust unit 41 are provided in each storage chamber 18. In the following, when the air supply unit 31 and the exhaust unit 41 of each storage chamber 18 are individually shown, the first air supply unit 31a, the second air supply unit 31b, and the third air supply are sequentially arranged from the upstream side in the transport direction. The part 31c, the 1st exhaust part 41a, the 2nd exhaust part 41b, and the 3rd exhaust part 41c are called. As shown in FIG. 1, the same applies to each component in each air supply unit 31 and each exhaust unit 41.

  The air supply unit 31 includes a plurality of air supply holes 32 formed in the ceiling 12 of each storage chamber 18, an air supply fan 33 that can change the rotation speed, and an air intake port 34 that can take in air outside the storage unit 10. With. The air supply holes 32 are ventilation holes formed at a plurality of locations on the ceiling 12 of each storage chamber 18, and supply the taken-in air into each storage chamber 18. The air supply fan 33 is driven to form a flow of air that is supplied to the storage chamber 18 by taking in external air, and the amount of air supplied to the storage chamber 18 can be controlled by changing the rotation speed. . In addition, it is preferable to provide the intake port 34 with a filter for blocking dust and the like when air is taken in.

  On the other hand, the exhaust unit 41 includes a plurality of exhaust holes 42 formed in the floor 13 of the storage chamber 18, an exhaust fan 43 that can change the rotation speed, and an exhaust port 44 that can exhaust air to the outside of the storage unit 10. Is provided. As shown in FIG. 2, the exhaust holes 42 are ventilation holes formed at a plurality of locations on the floor 13 of each storage chamber 18, and exhaust the air in each storage chamber 18. The exhaust fan 43 discharges air in the storage chamber 18 from the exhaust port 44 to the outside of the storage unit 10 by driving. The exhaust port 44 is provided with a filter that collects dust in each storage chamber 18 and dust generated by processing the glass plate G.

  Each accommodation chamber 18 has a pair of rectifying plates 50 arranged close to each other at a position facing the surface of the glass plate G to be conveyed. In the present embodiment, the rectifying plate 50 is a flat plate-like member, and is arranged to be parallel at a predetermined interval. In addition, it is preferable that the space | interval of the baffle plate 50 shall be comparable as the space | interval of the edge parts in the door 17 of the open state.

  Next, operation | movement of the glass plate conveying apparatus 1 concerning this invention is demonstrated. First, the glass plate G is set in the glass plate conveying apparatus 1. This glass plate G is manufactured in a glass plate manufacturing apparatus (not shown) on the upstream side of the manufacturing process and cut into a predetermined size. In the glass plate conveying apparatus 1, a plurality of upper portions of the glass plate G manufactured in this way are held by the suspension member 24. Further, the support member 23 to which the suspension member 24 is connected is coupled to the coupling member 25 and set on the moving rail 21. Thereby, it becomes possible to convey by the conveying means 20 of the glass plate conveying apparatus 1. In addition, the moving rail 21 may be extended to the upstream side of the accommodating part 10 of the glass plate conveying apparatus 1 shown in FIG. 1, and the several glass plate G may be made to stand by in the suspended state.

  When the glass plate G is set in the glass plate conveyance device 1, the door 17 is opened, and a drive motor (not shown) is driven to start conveyance in the direction of arrow A in FIG. As shown in FIG. 1, when the glass plate G is conveyed to a predetermined position in the first storage chamber 18a, the drive motor is stopped and the conveyance of the glass plate G is stopped. The stop position of the glass plate G is, for example, after a detection unit that detects the glass plate G carried into the storage unit 10 is provided in the carry-in unit 14, and the detection unit conveys the glass plate G for a predetermined distance from the detected state. Position by stopping. When the glass plate G stops at a predetermined position in the first storage chamber 18a, the door 17 is closed.

  Next, the air flow generating means 30 is operated to form an air flow in each storage chamber 18 and the atmospheric pressure in the storage chamber 18 is set to a positive pressure. Specifically, the air supply fan 33 of the air supply unit 31 and the exhaust fan 43 of the exhaust unit 41 are activated. As a result, external air taken in from the intake port 34 of the air supply unit 31 is supplied from the air supply hole 32 to each storage chamber 18, and air in each storage chamber 18 is sucked from the exhaust hole 42. Then, the air is discharged from the exhaust port 44 to the outside. Therefore, an air flow from the upper part to the lower part can be formed in each storage chamber 18. Here, the rotational speeds of the air supply fan 33 and the exhaust fan 43 are adjusted so that the amount of air supplied from the air supply unit 31 into each storage chamber 18 is larger than the amount of air exhausted from the exhaust unit 41. To do. Thereby, in each storage chamber 18, the inside of the storage chamber 18 can be made into a positive pressure. Note that the air supply fan 33 and the exhaust fan 43 may start operating before the glass plate G is conveyed to the housing unit 10.

  Further, in the present embodiment, a pressure difference is formed between the adjacent storage chambers 18 by adjusting the rotation speed of the air supply fan 33 in each storage chamber 18. Specifically, assuming that the amount of air exhausted from the adjacent storage chambers 18a and 18b is the same, the rotation speed of the supply fan 33b in the second storage chamber 18b is set to the rotation speed of the supply fan 33a in the first storage chamber 18a. Slower than. Thereby, in the second storage chamber 18b, the amount of air supplied is smaller than that of the first storage chamber 18a, so that the internal atmospheric pressure is lower than that of the first storage chamber 18a. In this way, a pressure difference can be formed between the adjacent storage chambers 18a and 18b.

  Subsequently, a predetermined processing is performed on the glass plate G in the first storage chamber 18a. At this time, in each storage chamber 18, since air flows from the upper air supply hole 32 toward the lower exhaust hole 42, dust on the surface of the first storage chamber 18 a and the glass plate G, Dust and the like generated by processing can be removed and discharged from the exhaust hole 42.

  When the processing to the glass plate G is completed, as shown in FIGS. 3 and 4, the door 17 is opened and the drive motor is driven to convey the glass plate G. At this time, as described above, since a pressure difference is formed between the first storage chamber 18a and the second storage chamber 18b, the first storage chamber 18a and the second storage chamber 18 are opened by opening the door 17. The chamber 18b communicates with each other, and an air flow is generated in the conveying direction at the communicating portion (indicated by a one-dot chain line arrow in FIG. 3). This air flow is formed over the entire vertical direction of the glass plate G. Therefore, along with the conveyance of the glass plate G, the surrounding air can be moved together with the glass plate G, and the air resistance of the conveyed glass plate G can be reduced. Therefore, it is possible to prevent the glass plate G from swinging in the thickness direction when the glass plate G is conveyed. When airflow is generated, all the doors 17 may be opened simultaneously (see FIG. 4), and only the storage chamber 18 in which the glass plate G is stored and the doors 17 of the adjacent storage chambers 18 are opened. It may be.

  When the processed glass plate G to be conveyed reaches a predetermined position in the second storage chamber 18b (indicated by a one-dot chain line in FIGS. 1 and 2), the conveyance of the glass plate G is stopped. In addition, another subsequent glass plate G is conveyed in the 1st storage chamber 18a. Thereafter, similarly to the above, the door 17 is closed and the glass plate G is subjected to predetermined processing in each of the storage chambers 18a and 18b. After the processing is completed, the door 17 is opened and the glass plate G is transported (see FIG. 3 and FIG. At this time, since the airflow generation means 30 is continuously operated, the interior of each storage chamber 18 is brought to a positive pressure by closing the door 17 and a pressure difference is formed between the adjacent storage chambers 18. be able to. Further, by opening the door 17, an air flow can be generated in the transport direction from the upstream storage chamber 18 toward the downstream storage chamber 18.

  By repeating the above operation, various processings can be performed on the glass plate G while preventing the glass plate G from swinging during conveyance. In addition, the moving rail 21 may be extended to the downstream side of the accommodating part 10 of the glass plate conveying apparatus 1, and the plurality of glass plates G that have been processed may be kept in a suspended state.

  Here, in order to eliminate the pressure difference by forming a pressure difference between the adjacent storage chambers 18a and 18b and opening the door 17, the door 17 also constitutes a pressure adjusting unit. In the present embodiment, the air supply unit 31 and the exhaust unit 41 are connected to the means for generating an air flow for removing dust, dust and the like in each storage chamber 18 and between the adjacent storage chambers 18. Since it can be commonly used as a means for adjusting the pressure of the apparatus, the configuration of the entire apparatus can be simplified.

  Moreover, it is preferable that the conveyance speed of the glass plate G and the speed of the airflow which generate | occur | produces between the adjacent storage chambers 18a and 18b are comparable. In this embodiment, when the pressure difference is 2.5 Pa, an air flow with a flow velocity of about 2 m / sec is generated in the transport direction, and when the pressure difference is 5 Pa, an air flow of about 3 m / sec is generated. Occur. Therefore, by setting the pressure difference between the adjacent storage chambers 18a and 18b to 2.5 Pa to 5 Pa and setting the transport speed of the glass plate G to 2 to 3 m / sec, the transport speed of the glass plate G and The speed of the airflow can be made comparable. Thereby, the air around the glass plate G moves together with the conveyed glass plate G, and the air resistance acting on the glass plate G is reduced, so that the swinging can be prevented. For this reason, even the thin glass plate G can be reliably prevented from swinging. In addition, when opening the door 17, you may adjust the flow velocity of the airflow which generate | occur | produces in a communicating part by adjusting the opening area of the door 17. FIG.

  Furthermore, in this embodiment, since it has the some storage chamber 18, the pressure in each storage chamber 18 is adjusted so that the atmospheric | air pressure in the adjacent downstream storage chamber 18 may become low. Specifically, when the conveyance speed of the glass plate G is set to 2 m / sec, the pressure difference between the adjacent storage chambers 18 is preferably 2.5 Pa. Assuming XPa, the pressure in the third storage chamber 18c on the most downstream side in the transport direction is X + 2.5 Pa, the second storage chamber 18b is X + 5 Pa, and the first storage chamber is X + 7.5 Pa. Adjust the pressure. In addition, in order to increase the conveyance speed of the glass plate G, it can respond by enlarging the atmospheric pressure difference in each storage chamber 18. That is, if the pressure difference in each storage chamber 18 is increased, the speed of the air flow generated when the door 17 is opened can be increased, so that the conveyance speed of the glass plate G can be increased. Thereby, the processing capability of the apparatus can be increased.

  Here, since a pair of rectifying plates 50 are arranged in each storage chamber 18, when the door 17 is opened in a state where a pressure difference is formed, an air flow is surely generated in the vicinity of the glass plate G. Can do. Specifically, since the pair of rectifying plates 50 are arranged at intervals similar to the intervals between the ends of the door 17 in the opened state, an airflow can be generated in the space between the rectifying plates 50. Therefore, an air flow can be generated efficiently and the air flow generating means 30 can be further labor-saving.

  In the above embodiment, the amount of air supplied into each storage chamber 18 is adjusted by adjusting the rotation speed of the air supply fan 33 in order to generate a pressure difference between the adjacent storage chambers 18. However, the present invention is not limited to this, and various methods for increasing the pressure in the storage chamber 18 on the upstream side in the transport direction can be employed. For example, an opening / closing shutter for adjusting the opening amount of the air supply hole 32 may be provided in the vicinity of the air supply hole 32. In this case, by adjusting the opening amount of the air supply hole 32 in the storage chamber 18 on the upstream side in the transport direction to be larger than the opening amount of the air supply hole 32 in the storage chamber 18 on the downstream side, The amount of air supplied to each storage chamber 18 can be adjusted without changing the rotation speed, and a pressure difference can be formed between adjacent storage chambers 18.

  On the other hand, the air pressure difference may be formed by adjusting the exhaust amount of the exhaust part 41 in a state where the supply amount of air to each storage chamber 18 is constant. For example, a shutter capable of adjusting the opening amount may be provided in the exhaust hole 42 of the storage chamber 18. In this case, by adjusting the opening amount of the exhaust hole 42 in the downstream storage chamber 18 to be larger than the opening amount of the exhaust hole 42 in the upstream storage chamber 18, the exhaust chamber 42 is discharged from each storage chamber 18. The amount of air to be adjusted can be adjusted, and a pressure difference can be formed.

  In any case, since the air pressure difference can be formed by increasing the air pressure in the upstream-side storage chamber 18 as described above, the door 17 is opened with the air pressure difference formed. An air flow can be generated in the conveying direction. Note that, when the atmospheric pressure difference is formed, the atmospheric pressure in each storage chamber 18 is set to a positive pressure. However, for example, the atmospheric pressure difference may be formed by setting the atmospheric pressure in the downstream storage chamber 18 to a negative pressure. .

  Moreover, in the said embodiment, although the door 17 for generating an airflow was provided between each storage chamber 18, the quantity of the air supplied to each storage chamber 18 is adjusted without providing the door 17. FIG. Thus, an air flow may be generated by forming a pressure difference. For example, during processing, the air supply amount and the exhaust amount in each storage chamber 18 may be adjusted to be equal to each other, and the air supply amount may be increased by increasing the air supply amount when the glass plate G is transported. . Also at this time, by increasing the amount of increase in the upstream storage chamber 18, it is possible to provide a difference in the amount of air supplied between the storage chambers 18. Thereby, a pressure difference is generated between the respective storage chambers 18, and an air flow can be generated in the transport direction.

  Furthermore, an air flow may be generated in the transport direction by a blowing means such as a fan or a blower when the glass plate G is transported without providing the housing portion 10 that houses the glass plate G. Also in this case, it is possible to generate an air flow in the transport direction when the glass plate G is transported, and it is possible to reduce the air resistance of the transported glass plate G and prevent swinging.

  In addition, in the said embodiment, although the air supply part 31 and the exhaust part 41 were provided in the accommodating part 10, you may provide only any one. In addition, the air supply holes 32 are formed in the ceiling 12, and the exhaust holes 42 are provided in the floor 13 to generate an air flow for removing dust and dust in the storage chamber 18. You may provide separately from the means to remove dust etc. In that case, you may provide the supply part and exhaust part which supply air in order to form an atmospheric | air pressure difference, for example in the side wall 11 grade | etc.,.

  Moreover, in order to adjust the pressure in the accommodating part 10, the external air taken in from the air supply part 31 was supplied, but it is not restricted to this, The air in each accommodating chamber 18 and other accommodating chambers 18 is supplied. It may be circulated. In this case, a circulation path connecting the exhaust port 44 and the intake port 34 may be formed, and air discharged from the exhaust port 44 may be sucked from the intake port 34. A circulation path may be provided for each storage chamber 18, and the air exhausted from each storage chamber 18 may be circulated collectively. At this time, it is preferable to arrange a filter for removing dust, dust and the like in the middle of the circulation path.

  Furthermore, the number of storage chambers 18 formed in the storage unit 10 is not limited to three, and may be two or less or four or more based on manufacturing-related processing performed on the glass plate G. Even in this case, similarly to the above, by forming a pressure difference between the adjacent storage chambers 18, it is possible to prevent the glass plate G from swinging during conveyance.

  In addition, the rectifying plates 50 installed in the respective storage chambers 18 are not limited to being arranged in parallel, and may be arranged so as to be inclined so that the interval between the rectifying plates 50 gradually decreases toward the downstream side. . Moreover, it may be a member having a curved surface instead of a flat plate shape, or a member having a different thickness depending on the place.

  Moreover, the conveyance direction of the glass plate G should just be the horizontal direction along the surface of a glass plate, and is not restricted to a horizontal direction, The direction inclined from the horizontal may be sufficient.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
