Description

  The present invention relates to a glass plate conveying apparatus and a glass plate manufacturing method.

  The glass plate manufacturing process includes a step of conveying the glass plate in a horizontal posture and a step of conveying the glass plate in an inclined posture. The horizontal posture is a posture in which the main surface of the glass plate is horizontal, and the inclined posture is a posture in which the main surface of the glass plate is inclined from the horizontal. If the glass plate is conveyed in an inclined posture, the treatment liquid adhering to the glass plate can be quickly dropped from the glass plate.

  Usually, since the glass plate is transported in a horizontal posture, when there is a step of transporting in a tilted posture, the posture of the glass plate is changed between a horizontal posture and a tilted posture with different tilt angles during the transport. It is necessary to change, and an apparatus for that purpose has been proposed (for example, see Patent Document 1).

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic plan view showing a glass plate manufacturing process in which a glass plate transport device 1 according to an embodiment of the present invention is disposed. The conveyance device 1 is disposed, for example, between a conveyance path R1 for end face processing and a conveyance path R2 for cleaning treatment. As indicated by white arrows, the glass plate G is conveyed in the order of the end surface processing conveyance path R1, the conveyance apparatus 1, and the cleaning conveyance path R2. The glass plate G is a rectangular flat plate, and is conveyed with its long side along the conveying direction.

  As shown in FIG. 2A, the glass plate G is transported in a horizontal posture P1 on the end surface processing transport path R1. On the other hand, as shown in FIG. 2 (C), the glass plate G is transported in an inclined posture P2 in the cleaning transport path R2. As shown in FIG. 2 (B), the orientation of the glass plate G in the transport apparatus 1 is the inclined posture in the cleaning transport path R2 from the horizontal orientation P1 (first orientation) in the end surface processing transport path R1. It is changed to P2 (second posture).

  In the end surface processing transport path R1, the transport apparatus 1, and the cleaning transport path R2, the transport direction of the glass plate G is along the horizontal direction. In the transport device 1 and the cleaning transport path R2, the glass plate G in the inclined posture P2 is tilted with respect to the horizontal plane H by rotating around an axis parallel to the transport direction. The inclination angle α is, for example, 4 ° to 6 °. In the drawings, the inclination angle α is large for easy understanding (the same applies to the following drawings). In the end surface processing transport path R1 and the transport apparatus 1, the inclination angle α of the glass plate G in the horizontal posture P1 is 0 °.

  As shown in FIGS. 3 and 4, the transport device 1 includes a belt conveyor 2 as a transport unit, a guide roller 3 as a guide unit, a positioning roller 4 as a positioning unit, and a support base as a support. 5 and the base part 6 are main components.

  The belt conveyor 2 has the conveyance surface Sc which conveys the glass plate G along a horizontal direction, supporting the main surface of the glass plate G from the downward direction. The belt conveyor 2 carries the glass plate G onto the belt conveyor 2 from the end surface processing conveyance path R1. Further, the belt conveyor 2 carries the glass plate G from the belt conveyor 2 to the cleaning transport path R2. The conveying direction by the belt conveyor 2 is along the horizontal direction, and is the direction from left to right in FIG. A plurality of belt conveyors 2 are arranged at intervals in the width direction of the conveyance path of the glass sheet G formed by the belt conveyor 2. The belt conveyor 2 is supported by the support base 5 via a support mechanism (not shown).

  In the following description, unless otherwise noted, the transport direction means the direction in which the glass plate G is transported by the belt conveyor 2, and the transport path is the transport path of the glass plate G formed by the belt conveyor 2. Shall mean.

  The guide roller 3 has a guide surface Sg that receives the glass plate G from the transport surface Sc and guides it along a direction orthogonal to the transport direction (see FIG. 7). The guide direction of the glass plate G by the guide roller 3 is a direction from bottom to top in FIG. A plurality of guide rollers 3 are fixed to the rotation support shaft 3a at intervals in the transport direction. A plurality of rotation support shafts 3 a are arranged between the plurality of belt conveyors 2. All the rotation support shafts 3a are arranged along the transport direction. Each rotation support shaft 3a is supported by the support base 5 via the first cylinder mechanism 3b. The guide roller 3 functions as a free roller when the rotation support shaft 3a is rotatably attached to the first cylinder mechanism 3b.

  The guide roller 3 can be moved up and down (moved along a direction perpendicular to the transport surface Sc) with respect to the support base 5 by the expansion and contraction of the first cylinder mechanism 3b. When the belt conveyor 2 conveys the glass plate G, the first cylinder mechanism 3b is in a shortened state, and the guide roller 3 is lowered to a retracted position where it does not contact the glass plate G. On the other hand, when the guide roller 3 guides the glass plate G, the first cylinder mechanism 3b is in the extended state, and the guide roller 3 is raised to the guide position. At this time, the glass plate G pushed up by the guide roller 3 is separated from the belt conveyor 2. When the guide roller 3 is in the guide position, the guide surface Sg is above the transport surface Sc. When the guide roller 3 is in the retracted position, the guide surface Sg is at a position below the transport surface Sc. The belt conveyor 2 does not move up and down with respect to the support base 5.

  Since the expansion and contraction operations of all the first cylinder mechanisms 3b are synchronized, the glass plate G supported by the guide roller 3 maintains the posture when the guide roller 3 is raised or lowered. Move in parallel.

  The positioning roller 4 abuts on an end portion (end surface) of the glass plate G guided by the guide surface Sg of the guide roller 3 and positions the glass plate G at a position in a direction orthogonal to the conveyance direction. A plurality of positioning rollers 4 are arranged at intervals along the transport direction. A plurality of support frames 4a to which a plurality of positioning rollers 4 are attached are arranged, and a second cylinder mechanism 4b is attached to each support frame 4a. The positioning roller 4 is rotatably attached to the support frame 4a and functions as a free roller. The rotation shaft of the positioning roller 4 is perpendicular to the transport surface Sc. The support frame 4a is supported by the support base 5 via the second cylinder mechanism 4b.

  The positioning roller 4 is moved along the width direction of the transport path by the expansion and contraction operation of the second cylinder mechanism 4b, and the positioning position near the belt conveyor 2 is retracted away from the belt conveyor 2 than the positioning position. Switch to position. The expansion and contraction operations of all the second cylinder mechanisms 4b are synchronized. The positioning roller 4 contacts the end of the glass plate G at the positioning position to position the glass plate G. Since the plurality of positioning rollers 4 are arranged along the conveying direction, the end portion of the glass plate G with which the positioning roller 4 at the positioning position abuts is arranged along the conveying direction.

  When the guide roller 3 guides the glass plate G, the second cylinder mechanism 4b is in the extended state, and the positioning roller 4 is in the positioning position. When the belt conveyor 2 conveys the glass plate G before positioning, the second cylinder mechanism 4b is in a shortened state and the positioning roller 4 is in the retracted position. Thereby, when the belt conveyor 2 conveys the glass plate G before positioning, it can prevent that the glass plate G and the positioning roller 4 interfere. In addition, when the belt conveyor 2 conveys the glass plate G after positioning, the positioning roller 4 may be in a positioning position or may be in a retracted position.

  The belt conveyor 2, the guide roller 3, and the positioning roller 4 are supported by a common support base 5. By tilting the support 5, the belt conveyor 2, the guide roller 3, and the positioning roller 4 are tilted.

  Support legs 5 a for supporting the support table 5 are provided below the support table 5. On the base part 6, the base support part 6a for supporting the support leg 5a is provided. The support leg 5a is swingably attached to the base support portion 6a by a swing shaft 5b. The swing shaft 5b is parallel to the transport surface Sc. Further, a third cylinder mechanism 5c is attached between the support base 5 and the base portion 6 so as to be swingable with respect to both. The axis of swing of the third cylinder mechanism 5c with respect to the support base 5 and the base portion 6 is parallel to the transport surface Sc.

  The support 5 swings (rotates) about the swing shaft 5b by the expansion and contraction of the third cylinder mechanism 5c. When the third cylinder mechanism 5c is in the shortened state, the support 5 is not tilted and is in a horizontal posture, and the glass plate G supported by the belt conveyor 2 or the guide roller 3 is in the horizontal posture P1. When the third cylinder mechanism 5c is in the extended state, the support base 5 is in the inclined posture, and the glass plate G supported by the belt conveyor 2 or the guide roller 3 is in the inclined posture P2.

  In addition, in order for the 1st cylinder mechanism 3b to deliver the glass plate G from the conveyance surface Sc to the guide surface Sg, while positioning the guide surface Sg relatively above the conveyance surface Sc, the positioned glass plate G Is a position changing unit that relatively positions the guide surface Sg below the transport surface Sc in order to transfer the guide surface Sg to the transport surface Sc.

  Further, the support base 5, the support leg 5a, the swing shaft 5b, the third cylinder mechanism 5c, the base portion 6, and the base support portion 6a include a transport surface angle changing unit that changes the inclination angle of the transport surface Sc, and a guide surface Sg. It is a guide surface angle change part which changes the inclination angle. That is, the conveyance surface angle changing unit and the guide surface angle changing unit are formed by a common angle changing unit (support base 5, support leg 5a, swing shaft 5b, third cylinder mechanism 5c, base unit 6, base support unit 6a). Composed.

  Next, the operation of the transport device 1 will be described.

  First, as shown in FIG. 4, the support base 5 is in a horizontal position (the third cylinder mechanism 5 c is in a shortened state), the guide roller 3 is in a retracted position (the first cylinder mechanism 3 b is in a shortened state), and the positioning roller 4. Is the retracted position (the second cylinder mechanism 4b is in a shortened state).

  Then, as shown in FIG. 5, the belt conveyor 2 is driven, and the glass plate G is carried onto the belt conveyor 2 from the end surface processing conveyance path R <b> 1. Then, when the glass plate G is conveyed to a predetermined position on the belt conveyor 2, the belt conveyor 2 stops. In this state, the glass plate G is in the horizontal posture P1.

  Next, as shown in FIG. 6, the first cylinder mechanism 3b is in the extended state, and the guide roller 3 is raised to the guide position. Thereby, the glass plate G is pushed up (supported) by the guide roller 3 and is separated from the belt conveyor 2. That is, the guide surface Sg of the guide roller 3 receives the glass plate G from the transport surface Sc of the belt conveyor 2. When the guide roller 3 is raised and at the guide position, the glass plate G remains in the horizontal posture P1. After the first cylinder mechanism 3b is extended, the second cylinder mechanism 4b is in the extended state (see the solid line arrow in FIG. 6), and the positioning roller 4 is in the positioning position. Note that the extension of the first cylinder mechanism 3b and the extension of the second cylinder mechanism 4b may be performed simultaneously.

  Then, as shown in FIG. 7, the third cylinder mechanism 5 c is in an extended state, and the support base 5 is inclined to assume an inclined posture. Thereby, the glass plate G supported by the guide roller 3 is in the inclined posture P2. That is, the glass plate G received by the guide surface Sg is changed from the horizontal posture P1 to the inclined posture P2 by changing the inclination angle of the guide surface Sg. The positioning roller 4 is disposed on the lower side of the guide surface Sg.

  Then, as shown in FIG. 8, the glass plate G moves on the guide roller 3 along the width direction of the transport path while being guided by the guide roller 3 due to the action of gravity. And the edge part of the glass plate G contact | abuts to the positioning roller 4, and the glass plate G stops. Even in this state, the glass plate G is in the inclined posture P2.

  Thereafter, as shown in FIG. 9, the first cylinder mechanism 3b is shortened, and the guide roller 3 is lowered to the retracted position. Thereby, the glass plate G will be in the state supported by the belt conveyor 2. FIG. That is, the positioned glass plate G is transferred from the guide surface Sg of the guide roller 3 to the transport surface Sc. Even if the glass plate G is delivered to the transport surface Sc, the end of the glass plate G is in contact with the positioning roller 4, and the glass plate G remains positioned. In this state, the glass plate G is in the inclined posture P2.

  And as shown in FIG. 10, the belt conveyor 2 is driven and the glass plate G is carried out from the belt conveyor 2 to the washing conveyance path R2. At this time, the end portion of the glass plate G slides with the positioning roller 4. However, since the positioning roller 4 is a free roller, there is little friction and damage to the end portion of the glass plate G can be suppressed. When the glass plate G has been unloaded to the cleaning transport path R2, the belt conveyor 2 is stopped.

  Then, as shown in FIG. 11, the third cylinder mechanism 5c is shortened, and the support base 5 returns to the horizontal posture. At the same time, the second cylinder mechanism 4b is shortened, and the positioning roller 4 is moved to the retracted position. Thus, a series of operations of the transport apparatus 1 is completed, and the transport apparatus 1 is in the initial state.

  The conveyance device 1 configured as described above can enjoy the following effects.

  The guide surface Sg of the guide roller 3 receives the glass plate G from the transport surface Sc and guides it along the direction orthogonal to the transport direction. Then, the positioning roller 4 contacts the end of the glass plate G guided by the guide surface Sg, and positions the glass plate G. The guide direction of the glass plate G by the guide surface Sg of the positioning roller 4 is along the width direction of the transport path in plan view. Therefore, when the glass plate G guided by the guide surface Sg of the guide roller 3 and positioned by the positioning roller 4 is transferred to the transport surface Sc of the belt conveyor 2, the width direction of the transport path for the glass plate G Is determined by the positioning roller 4. Therefore, the position in the width direction of the conveyance path for the glass plate G when the belt conveyor 2 carries out the glass plate G in the inclined posture P2 is constant. That is, according to the glass plate conveying apparatus 1 of the present embodiment, the position of the glass plate G in the width direction of the conveying path after the posture of the glass plate G is changed between the horizontal posture P1 and the inclined posture P2. Can be made constant. In addition, the delivery of the glass plate G between the transport surface Sc and the guide surface Sg is performed by changing the relative position in the vertical direction of the transport surface Sc and the guide surface Sg without moving the glass plate G in the transport direction. Do. Therefore, posture change and positioning can be performed quickly, and the installation space for the apparatus can be reduced.

  The present invention is not limited to the above embodiment, and various modifications are possible within the scope of the technical idea. For example, in the above-described embodiment, all of the belt conveyor 2, all of the guide rollers 3, and all of the positioning rollers 4 are supported by the common support base 5, as shown in FIG. Thus, it may be distributed and supported by a plurality of support bases 5. In this case, while the glass plate G is being carried out from the belt conveyor 2 to the cleaning conveyance path R2, the glass plate G is returned to the horizontal posture sequentially from the support base 5 that supports the belt conveyor 2 that has finished carrying the glass plate G. If the glass plate G is carried onto the belt conveyor 2 from the end surface processing conveyance path R1, the conveyance efficiency of the glass plate G can be improved.

  Moreover, in the said embodiment, although the belt conveyor 2 was used as a conveyance part, it is not limited to this, For example, as shown to FIG. 12 (B), you may use the roller conveyor 7. FIG. In the illustrated example, the roller conveyor 7 is long in the width direction of the conveyance path, and is supported by a support base 5 different from the guide roller 3.

  Moreover, in the said embodiment, although the belt conveyor 2 and the guide roller 3 were supported by the common support stand 5 and were inclined by the inclination of the support stand 5, it is not limited to this. For example, as shown in FIG. 12C, the guide roller 3 may be supported by the base portion 6 via the first cylinder mechanism 3b. In this case, as shown in FIG. 12C, the guide roller 3 may be inclined by varying the length of the first cylinder mechanism 3b in the extended state. In this case, as shown in FIG. 12C, the inclination angle of the guide surface Sg when guiding the glass plate G is different from the inclination angle of the transport surface Sc when the glass plate G is delivered. Also good.

  In the above embodiment, the movable positioning roller 4 is used as the positioning unit. However, it is sufficient that the glass plate G guided by the guide unit can be received, and the positioning unit 8 shown in FIG. As described above, it may be a non-moving one or a roller.

  In the above embodiment, the received glass plate G is guided downward by the action of gravity in a state where the guide roller 3 composed of a free roller as a guide portion is tilted. The glass plate G may be guided toward the positioning portion in a horizontal posture by driving the roller in a state where the roller is not inclined.

  Moreover, in the said embodiment, although the guide roller 3 which consists of a free roller was used as a guide part, what is necessary is just to be able to guide the received glass plate G to the inclination downward in the inclined state. An air float table or the like may be used.

  In the above embodiment, the support table 5 is inclined after the guide roller 3 receives the glass plate G from the belt conveyor 2. However, after the support table 5 is inclined, the guide roller 3 is moved to the belt conveyor 2. You may receive the glass plate G from.

  Moreover, in the said embodiment, in the conveying apparatus 1, although it changed from the horizontal attitude | position P1 to the inclination attitude | position P2, you may be changed from the inclination attitude | position P2 to the horizontal attitude | position P1. In that case, it is preferable that a pressing portion for pressing the glass plate G against the positioning roller 4 is provided in a state where the positioning roller 4 receives the glass plate G. By this pressing part, when the attitude | position of the glass plate G is changed into the horizontal attitude | position P1, it can suppress more reliably that the glass plate G shift | deviates to the opposite side to the positioning roller 4. FIG.

  Moreover, in the said embodiment, although the conveying apparatus 1 was changed from the horizontal attitude | position P1 to the inclination attitude | position P2, in the conveying apparatus 1, the angle with respect to the horizontal direction in the surface orthogonal to a conveyance direction differs, and an inclination attitude | position and an inclination. You may change the attitude | position of the glass plate G to an attitude | position.

  Moreover, in the said embodiment, although the shape of the glass plate G was a rectangular-shaped flat plate, it is not limited to this, For example, a circular glass plate may be sufficient, and it may be a curved glass plate. Good.
