Description

Glass plate conveying device and glass plate manufacturing method

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

In the manufacturing process of the glass plate, there are 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 horizontal. If the glass plate is transported in an inclined posture, the treatment liquid adhering to the glass plate can be quickly dropped from the glass plate.

The glass plate is usually carried in a horizontal position. Therefore, if there is a step of carrying the glass plate in an inclined position, it is necessary to change the position of the glass plate between the horizontal position and the inclined position with different inclination angles during the transportation. A device is proposed (for example, refer to Patent Document 1). [Prior Art Document] [Patent Document]

[Patent Document 1] Japanese Patent Laid-Open No. 9-226916

[Problems to be Solved by the Invention] However, from the viewpoint of stably handling the glass plate, it is desirable that the glass plate is transported in a direction orthogonal to the transport direction (hereinafter, also referred to as "the width direction of the transport path" ) Are in the same position. However, when the posture of the glass plate is changed between the horizontal posture and the inclined posture, there is a possibility that the position of the glass plate is shifted, and there is a possibility that the position is different for each glass plate. In addition, this problem is not limited to the case where the posture of the glass plate is changed between the horizontal posture and the inclined posture. It may also occur when the posture of the glass plate is changed between the inclined posture and the inclined posture with different inclination angles. .

In view of the above-mentioned circumstances, the present invention has a technical problem to align the positions of the glass plates in the width direction of the conveyance path after changing the posture of the glass plates. [Means to solve the problem]

The glass plate conveying device of the present invention pioneered to solve the problem conveys glass plates in a predetermined conveying direction, and the glass plate conveying device includes a conveying section having a conveying unit for conveying the glass plate in the conveying direction Surface, the glass plate is carried in in a first posture, and the glass plate is carried out in a second posture that is different from the first posture at an inclination angle with respect to the horizontal plane; The conveying surface receives the glass plate and guides the glass plate in a direction orthogonal to the conveying direction; a positioning portion abuts against the end of the glass plate guided by the guide surface, and opposes the glass Plate positioning; a conveying surface angle changing part to change the inclination angle of the conveying surface; and a position changing part to relatively position the guide surface in order to transfer the glass plate from the conveying surface to the guide surface Above the conveyance surface, and in order to transfer the positioned glass sheet from the guide surface to the conveyance surface, the guide surface is relatively positioned below the conveyance surface.

In the said structure, the guide surface of a guide part receives a glass plate from a conveyance surface, and guides the said glass plate in the direction orthogonal to a conveyance direction. In addition, the positioning portion abuts on the end of the glass plate guided by the guide surface, and positions the glass plate. The guide direction of the guide surface of the guide part is along the width direction of the conveyance path (of the conveyance part) in a plan view of the guide direction of the glass plate. Therefore, when the glass sheet guided by the guide surface of the guide portion and positioned by the positioning portion is transferred to the conveying surface of the conveying portion, the position of the glass sheet in the width direction of the conveying path is determined by the positioning portion. Therefore, when the conveyance part unloads the glass plate in the second posture, the position of the glass plate in the width direction of the conveyance path coincides. That is, according to the conveyance apparatus of the glass plate of this invention, after changing the posture of a glass plate, the position of the width direction of a conveyance path of a glass plate can be matched. In addition, the transfer of the glass plate between the conveyance surface and the guide surface is performed by changing the relative position of the conveyance surface and the guide surface in the vertical direction without moving the glass plate in the conveyance direction. Therefore, posture changes and positioning can be performed quickly, and the installation space of the device can be reduced.

In the above configuration, a guide surface angle changing section for changing the inclination angle of the guide surface may also be included, and by changing the inclination angle of the guide surface, the glass plate received by the guide surface is free from The first posture is changed to the second posture.

With such a structure, the glass plate can be guided to the positioning part in the process of changing the inclination angle of the guide surface. Therefore, the posture change and positioning can be performed at the same time, and the time required for the posture change and positioning of the glass plate can be further shortened.

In the above configuration, it may be that the conveying surface angle changing portion and the guiding surface angle changing portion include a common angle changing portion, and the common angle changing portion is configured to support the conveyance by using a common support. The supporting body is tilted to tilt the conveying part and the guide part to support the guide part.

With such a configuration, the mechanism for tilting the conveying part and the guide part can be shared, and therefore the manufacturing cost can be reduced.

In the above configuration, it may be that the guide portion includes a plurality of free rollers.

With this structure, the tilted glass plate can be guided and positioned by the action of gravity. Therefore, the guide portion can be manufactured while suppressing the manufacturing cost, and the running cost of the device can be reduced.

In the above configuration, the first posture may be a horizontal posture, and the second posture may be an inclined posture.

With such a configuration, the posture change and positioning of the glass plate between the end face processing and the cleaning treatment of the glass plate can be quickly performed.

Furthermore, the manufacturing method of the glass plate of the present invention, which was pioneered in order to solve the problem, includes the step of conveying the glass plate in a predetermined conveying direction, and the manufacturing method of the glass plate includes the following steps: The conveying section of the conveying surface of the glass plate is a step of loading the glass plate in the first posture; by relatively positioning the guide surface of the guide section above the conveying surface, the guide surface is moved from the The step of receiving the glass plate on a conveying surface and guiding the glass plate by the guide surface in a direction orthogonal to the conveying direction; making the end of the glass plate guided by the guide surface abut against Positioning part, the step of positioning the glass plate; by relatively positioning the guiding surface of the guiding part below the conveying surface, the positioned glass plate is transferred from the guiding surface to the The step of the conveying surface; and the step of transporting the glass plate transferred to the conveying surface by the conveying part in a second posture that has an inclination angle with respect to a horizontal plane that is different from the first posture.

According to the said structure, the action and effect substantially the same as the 1st structure of the conveyance apparatus of a glass plate can be acquired. [Effects of the invention]

As described above, according to the present invention, the position of the glass plate in the width direction of the conveyance path can be aligned after changing the posture of the glass plate.

Hereinafter, a mode for implementing the present invention will be described based on the drawings.

Fig. 1 is a schematic plan view showing a manufacturing process of a glass plate provided with a glass plate conveying device 1 according to an embodiment of the present invention. The conveying device 1 is arranged, for example, between the conveying path R1 for end surface processing and the conveying path R2 for cleaning processing. As shown by a white arrow, the glass plate G is conveyed in the order of the conveyance path R1 for end surface processing1, the conveying apparatus 1, and the conveyance path R2 for cleaning. 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 conveyed in the horizontal posture P1 in the conveyance path R1 for end surface processing. On the other hand, as shown in FIG. 2C, the glass plate G is conveyed in the inclined posture P2 in the conveyance path R2 for cleaning. And, as shown in FIG. 2B, the posture of the glass plate G in the conveying device 1 is changed from the horizontal posture P1 (first posture) in the end surface processing conveying path R1 to the inclined posture P2 (first posture) in the cleaning conveying path R2. Second posture).

In the conveying path R1 for end surface processing, the conveying device 1, and the conveying path R2 for cleaning, the conveyance direction of the glass plate G is along a horizontal direction. In the conveying device 1 and the cleaning conveying path R2, the glass plate G in the inclined posture P2 is inclined with respect to the horizontal plane H by rotating about an axis parallel to the conveying direction. The inclination angle α is, for example, 4° to 6°. In addition, for ease of understanding, the inclination angle α is slightly larger in the description of the figure (the same applies to the following figures). In addition, in the conveying path R1 for end surface processing and the conveying device 1, the inclination angle α of the glass plate G in the horizontal posture P1 is 0°.

As shown in Figures 3 and 4, the main components of the conveying device 1 are: a belt conveyor as a conveying part, a guide roller 3 as a guide part, a positioning roller 4 as a positioning part, and a support body Support stand 5 and base part 6.

The belt conveyor 2 has a conveyance surface Sc that supports the main surface of the glass plate G from below and conveys the glass plate G in the horizontal direction. The belt conveyor 2 carries the glass plate G into the belt conveyor 2 from the conveying path R1 for end surface processing. And the belt conveyor 2 carries out the glass plate G from the belt conveyor 2 to the conveyance path R2 for cleaning. The conveying direction of the belt conveyor 2 is along the horizontal direction, which is a direction from left to right in FIG. 3. The belt conveyor 2 is arrange|positioned at intervals in the width direction of the conveyance path of the glass sheet G formed by the belt conveyor 2, and is arrange|positioned in multiple numbers. The belt conveyor 2 is supported on the support stand 5 via a support mechanism (not shown).

In addition, in the following description, unless otherwise noted, the conveying direction refers to the direction in which the glass plate G is conveyed by the belt conveyor 2, and the conveying path refers to the conveying path of the glass plate G formed by the belt conveyor 2 .

The guide roller 3 has a guide surface Sg that receives the glass sheet G from the conveyance surface Sc and guides the glass sheet G in a direction orthogonal to the conveyance direction (see FIG. 7 ). The guiding direction of the glass plate G by the guiding roller 3 is a direction from the bottom to the top in FIG. 3. The plurality of guide rollers 3 are fixed to the rotation support shaft 3a at intervals in the conveying direction. The plurality of rotation support shafts 3a are arranged between the plurality of belt conveyors 2. All the rotation support shafts 3a are arranged along the conveyance direction. Each rotation support shaft 3a is supported by the support stand 5 via the 1st cylinder mechanism 3b. The guide roller 3 is rotatably attached to the first cylinder mechanism 3b by the rotation support shaft 3a, and functions as a free roller.

The guide roller 3 can be raised and lowered with respect to the support table 5 (moved in a direction perpendicular to the conveying surface Sc) by the expansion and contraction operation of the first air cylinder mechanism 3 b. When the glass sheet G is conveyed on the belt conveyor 2, when the first cylinder mechanism 3b is in the shortened state, the guide roller 3 is lowered to a retracted position where it does not contact the glass sheet G. On the other hand, when the guide roller 3 guides the glass sheet G, the guide roller 3 rises to the guide position when the first air cylinder mechanism 3b is in the extended state. At this time, the glass plate G held up by the guide roller 3 leaves the belt conveyor 2. When the guide roller 3 is in the guide position, the guide surface Sg is positioned above the conveyance surface Sc. When the guide roller 3 is in the retracted position, the guide surface Sg is located below the conveyance surface Sc. In addition, the belt conveyor 2 does not move up and down with respect to the support stand 5.

The expansion and contraction operations of all the first air cylinder mechanisms 3b are synchronized. Therefore, when the guide roller 3 is raised or lowered, the glass plate G supported by the guide roller 3 moves in parallel while maintaining its posture.

The positioning roller 4 abuts on the end (end surface) of the glass sheet G guided by the guide surface Sg of the guide roller 3, and positions the position of the glass sheet G in the direction perpendicular to the conveying direction. A plurality of positioning rollers 4 are arranged at intervals in the conveying 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 axis of the positioning roller 4 is perpendicular to the conveying surface Sc. The support frame 4a is supported by the support stand 5 via the second cylinder mechanism 4b.

The positioning roller 4 moves in the width direction of the conveying path by the expansion and contraction action of the second cylinder mechanism 4b, and is located at a positioning position near the belt conveyor 2 and farther away from the belt conveyor 2 than the positioning position. Switch between the retreat positions. All the telescopic actions of the second cylinder mechanism 4b are synchronized. The positioning roller 4 abuts on the end of the glass plate G at the positioning position, and positions the glass plate G. Since the some positioning roller 4 is arrange|positioned along the conveyance direction, the edge part of the glass plate G which the positioning roller 4 of a positioning position abuts is arrange|positioned along the conveyance direction.

When the guide roller 3 guides the glass sheet G, the second air cylinder mechanism 4b is in the extended state, and the positioning roller 4 is in the positioning position. When the glass sheet G before positioning is conveyed on the belt conveyor 2, when the second cylinder mechanism 4b is in the shortened state, the positioning roller 4 is in the retracted position. This can prevent the glass plate G from interfering with the positioning roller 4 when the glass plate G before positioning is conveyed on the belt conveyor 2. In addition, when the glass sheet G after positioning is conveyed by the belt conveyor 2, the roller 4 for positioning may be in a positioning position or it may be in a retracted position.

The belt conveyor 2, the guide roller 3, and the positioning roller 4 are supported on a common support table 5. The belt conveyor 2, the guide roller 3, and the positioning roller 4 are inclined by the support table 5 inclining.

A supporting leg 5a for supporting the supporting table 5 is provided on the underside of the supporting table 5. The base part 6 is provided with a base support part 6a for supporting the support leg 5a. The support leg 5a is swingably attached to the base support portion 6a by the swing shaft 5b. The swing axis 5b is parallel to the conveying surface Sc. Moreover, between the support stand 5 and the base part 6, the 3rd cylinder mechanism 5c is attached so that it can sway freely with respect to both. The axis on which the third cylinder mechanism 5c oscillates with respect to the support stand 5 and the base part 6 is parallel to the conveyance surface Sc.

The support base 5 swings (rotates) around the swing shaft 5b by the expansion and contraction operation of the third cylinder mechanism 5c. When the third cylinder mechanism 5c is in the shortened state, the support table 5 is not inclined but 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 table 5 is in an inclined posture, and the glass plate G supported by the belt conveyor 2 or the guide roller 3 is in an inclined posture P2.

In addition, the first air cylinder mechanism 3b is to transfer the glass sheet G from the conveying surface Sc to the guide surface Sg while the guide surface Sg is relatively positioned above the conveying surface Sc, and to transfer the positioned glass sheet G from the guide surface Sg. The position change part where the guide surface Sg is relatively positioned below the conveyance surface Sc to the conveyance surface Sc.

Furthermore, the support stand 5, the support leg 5a, the swing shaft 5b, the third cylinder mechanism 5c, the base part 6, and the base support part 6a are a conveying surface angle changing section that changes the inclination angle of the conveying surface Sc and the inclination angle of the guide surface Sg. The guide surface angle change part. That is, the conveying surface angle changing portion and the guiding surface angle changing portion include a common angle changing portion (support stand 5, support leg 5a, swing shaft 5b, third cylinder mechanism 5c, base 6 and base support 6a).

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

Initially, as shown in Fig. 4, the support stand 5 is in a horizontal posture (the third cylinder mechanism 5c is in the shortened state), the guide roller 3 is in the retracted position (the first cylinder mechanism 3b is in the retracted state), and the positioning roller 4 is in 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 in to the belt conveyor 2 from the conveyance path R1 for end surface processing. After that, when the glass sheet 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 1st cylinder mechanism 3b becomes an extended state, and the guide roller 3 rises and becomes a guide position. Thereby, the glass plate G is lifted (supported) by the guide roller 3, and leaves the belt conveyor 2. That is, the guide surface Sg of the guide roller 3 receives the glass plate G from the conveyance surface Sc of the belt conveyor 2. When the guide roller 3 is raised and when it is in the guide position, the glass plate G maintains the horizontal posture P1. After the first cylinder mechanism 3b is extended, the second cylinder mechanism 4b is in the extended state (refer to the solid arrow in FIG. 6), and the positioning roller 4 is in the positioning position. In addition, the expansion of the first cylinder mechanism 3b and the second cylinder mechanism 4b may be performed at the same time.

After that, as shown in FIG. 7, the third cylinder mechanism 5c is in an extended state, and the support table 5 is inclined to be in an inclined posture. Thereby, the glass plate G supported by the guide roller 3 becomes the inclined posture P2. That is, by changing the inclination angle of the guide surface Sg, the glass plate G received by the guide surface Sg is changed from the horizontal posture P1 to the inclined posture P2. In addition, the positioning roller 4 is arranged on the obliquely 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 conveyance path while being guided by the guide roller 3 by the action of gravity. Then, the end of the glass plate G abuts on the positioning roller 4, and the glass plate G stops. In this state, the glass plate G is also in the inclined posture P2.

Thereafter, as shown in FIG. 9, the first cylinder mechanism 3b is in a shortened state, and the guide roller 3 is lowered to a retracted position. Thereby, the glass plate G is in the state supported by the belt conveyor 2. That is, the positioned glass sheet G is transferred from the guide surface Sg of the guide roller 3 to the conveyance surface Sc. Even if it is transferred to the conveyance surface Sc, the edge part of the glass plate G abuts on the roller 4 for positioning, and the glass plate G is the state after positioning. In this state, the glass plate G is in the inclined posture P2.

Then, 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 conveyance path R2 for cleaning. At this time, the end of the glass plate G slides with the positioning roller 4, but since the positioning roller 4 is a free roller, friction is small, and damage to the end of the glass plate G can be suppressed. When the conveyance of the glass plate G to the cleaning conveyance path R2 is finished, the belt conveyor 2 is stopped.

After that, as shown in FIG. 11, the third cylinder mechanism 5c is brought into a shortened state, and the support base 5 returns to a horizontal posture. At the same time, the second cylinder mechanism 4b is in a shortened state, and the positioning roller 4 moves to a retracted position. Thereby, the series of operations of the conveying device 1 ends, and the conveying device 1 becomes the initial state.

The following effects can be enjoyed in the transport mechanism 1 configured as described above.

The guide surface Sg of the guide roller 3 receives the glass plate G from the conveyance surface Sc, and guides the said glass plate G in the direction orthogonal to a conveyance direction. In addition, the positioning roller 4 abuts on the end of the glass plate G guided by the guide surface Sg, and positions the glass plate G. The guiding direction of the guide surface Sg of the positioning roller 4 to the glass sheet G is along the width direction of the conveyance path in a plan view. Therefore, when the glass sheet G guided by the guide surface Sg of the guide roller 3 and positioned by the positioning roller 4 is transferred to the conveying surface Sc of the belt conveyor 2, the position of the glass sheet G in the width direction of the conveying path is changed from The positioning is determined by the roller 4. Therefore, when the belt conveyor 2 carries out the glass sheet G in the inclined posture P2, the position of the glass sheet G in the width direction of the conveyance path coincides. That is, according to the conveyance apparatus 1 of the glass plate of this invention, after changing the posture of the glass plate G between the horizontal posture P1 and the inclined posture P2, the position of the glass plate G in the width direction of a conveyance path can be matched. In addition, the transfer of the glass sheet G between the conveyance surface Sc and the guide surface Sg is performed by changing the relative position of the conveyance surface Sc and the guide surface Sg in the vertical direction without moving the glass sheet G in the conveyance direction. Therefore, posture changes and positioning can be performed quickly, and the installation space of the device can be reduced.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of its technical idea. For example, in the above-mentioned embodiment, all the belt conveyors 2, all the guide rollers 3, and all the positioning rollers 4 are supported by the common support table 5. However, as shown in FIG. 12A, it may be allocated to a plurality of supports Stand 5 to support. At this time, if the glass plate G is carried out from the belt conveyor 2 to the cleaning conveying path R2, the supporting table 5 supporting the belt conveyor 2 that has finished the conveying of the glass plate G is sequentially used By returning it to the horizontal posture, and carrying the glass plate G onto the belt conveyor 2 from the conveying path R1 for end surface processing, the conveying 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, you may use a roller conveyor (roller conveyor) 7 as shown to FIG. 12B. In the example shown in the figure, the roller conveyor 7 is long in the width direction of the conveyance path, and is supported by a support stand 5 different from the guide roller 3.

In addition, in the above-mentioned embodiment, the belt conveyor 2 and the guide roller 3 are supported by the common support stand 5 and are inclined by the inclination of the support stand 5, but it is not limited to this. For example, as shown in FIG. 12C, the guide roller 3 may be supported by the base part 6 via the 1st cylinder mechanism 3b. At this time, as shown in FIG. 12C, the guide roller 3 may be inclined by varying the length of the extended state of the first cylinder mechanism 3b. At this time, as shown in FIG. 12C, the inclination angle of the guide surface Sg when the glass plate G is guided may be different from the inclination angle of the conveyance surface Sc when the glass plate G is handed over.

Furthermore, in the above-mentioned embodiment, the movable positioning roller 4 is used as the positioning portion, but it is sufficient as long as it can receive the glass plate G guided by the guide portion, and it may be the positioning portion 8 as shown in FIG. 12C. Those who do not move may not be rollers.

Moreover, in the above-mentioned embodiment, in the state where the guide roller 3 including the free roller as the guide portion is inclined, the received glass sheet G is guided obliquely downward by the action of gravity, but the rollers may also be provided The driving mechanism guides the glass plate G toward the positioning part in a horizontal posture by driving the rollers in a state where the rollers are not inclined.

Furthermore, in the above-mentioned embodiment, the guide roller 3 including a free roller is used as the guide, but it is sufficient as long as it can guide the received glass sheet G obliquely downward in a tilted state, so it serves as a guide For example, an air float table can also be used.

Furthermore, in the above-mentioned embodiment, after the guide roller 3 receives the glass sheet G from the belt conveyor 2, the support table 5 is tilted, but after the support table 5 is tilted, the guide roller 3 may be used from the belt conveyor 2Receive the glass plate G.

Furthermore, in the above-mentioned embodiment, in the conveying device 1, the horizontal posture P1 is changed to the inclined posture P2, but it may be changed from the inclined posture P2 to the horizontal posture P1. At that time, it is preferable to provide a pressing part which presses the glass plate G to the positioning roller 4 in a state in which the glass plate G is received by the positioning roller 4. By the said pressing part, when the posture of the glass plate G is changed to the horizontal posture P1, the deviation of the glass plate G to the opposite side of the roller 4 for positioning can be suppressed more reliably.

Furthermore, in the above-mentioned embodiment, in the conveying device 1, the horizontal posture P1 is changed to the inclined posture P2. However, in the conveying device 1, the posture of the glass plate G can be changed to be in a plane orthogonal to the conveying direction. The tilt posture and the tilt posture with different angles relative to the horizontal direction.

Moreover, in the said embodiment, the shape of the glass plate G is a rectangular flat plate, but it is not limited to this, For example, it may be a round glass plate or a curved glass plate.
