Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mechanism for conveying a glass plate in a vertical direction in the field of precision cleaning of the glass plate.

[0002]

[Prior art]

 As a conventional glass plate vertical transfer method, a method of transferring a glass plate vertically on a belt conveyor is known.

[0003]

[Problems to be solved by the device]

 In the conventional technology, the glass plate is placed on the conveyor belt and is conveyed by the frictional force against its own weight.Therefore, the glass plate is prevented from being conveyed due to strong contact with the guide or external force. In such a case, the conveyor belt and the glass plate slipped or were caught, making the transportation condition extremely unstable, which often resulted in abnormal transportation.

For this reason, there is also a type in which a driving device is also provided above the glass plate to carry it, but when an extra mechanism is required or when it is used in a precision cleaning machine for glass plates, the mechanism part needs to be removed from the mechanism part. The generated particles (fine dust of the level of μm) often adhere to the glass plate and prevent precise and clean cleaning. The present invention has been devised to solve these problems of the conventional technology, and thus provides a mechanism that is simple and stable, and that enables precise and highly clean cleaning while transporting glass sheets. Is what you are trying to do.

[0005]

[Means for Solving the Problems]

 To achieve the above-mentioned object, the transport mechanism in the present invention comprises a drive roller (3) in which a drive shaft (11) and a driven shaft (5) are connected by a universal joint (9), and a drive shaft (12). The driven shaft (6) is connected to the drive roller (4) by the universal joint (10), and the contraction ring (7) is stretched, and the rollers are arranged side by side around the transport line.

A guide roller (2) is provided below the center of the carrying line, and a guide roller (8) is provided above the carrying line, and these are arranged continuously in the direction of the carrying line.

[0007]

[Action]

 The driving force transmitted from the motor is transmitted to the drive shaft (11) and the drive shaft (12), and the drive roller (3) is rotated rightward through the universal joint (9) and the universal joint (10) to drive the drive roller (3). 4) rotates counterclockwise. That is, the outer peripheral portions of the drive roller (3) and the drive roller (4) rotate in opposite directions while contacting with each other due to the tension of the contraction ring (7).

Since the guide roller (2) and the guide roller (8) can freely rotate with respect to external force, when the glass plate is inserted from the portion A of FIG. 2, the guide roller (2) and the guide roller (8) are inserted. ), The glass plate is given a constant driving force while being sandwiched between the left and right driving rollers, and stable conveyance can be performed.

【Example】

 Embodiments of the present invention will be described with reference to the drawings. 1 is a partial sectional front view showing an embodiment of the present invention, FIG. 2 is a plan view, FIG. 3 is a partial sectional side view, FIG. 4 is an enlarged partial sectional front view, and FIG. Is.

In the embodiment, the drive shaft (11) and the driven shaft (5) are connected by the universal joint (9), and the drive roller (3) above the central fulcrum of the universal joint (9) is , The axis can be tilted in any direction around the central fulcrum. Further, a contraction ring guide (15) is provided above the universal joint (9), and even if the center driven shaft (5) rotates, the contraction ring guide (15) shares a sliding surface. As a result, they do not rotate together.

One of the drive rollers (4) has a similar structure, and the drive shaft (12) and the driven shaft (6) are connected by a universal joint (10), and the shaft of the drive roller (4) is connected. The center of the universal joint (10) can be freely tilted about the central fulcrum of the universal joint (10), and the contraction ring guide (16) provided at the upper part of the universal joint (10) also has a central driven shaft ( If 6) rotates, it is designed not to rotate with it. Then, the drive roller (3) and the drive roller (4) are installed on the left and right of the conveyance line.

Further, as shown in FIG. 5, a tension ring-shaped contraction ring (7) is wound around the two contraction ring guides. Since the driven shaft and the contraction ring guide share a sliding surface instead of being integral with each other, the driven shaft can rotate in any direction.

Immediately below the portion where the outer circumference of the drive ring (13) and the outer circumference of the drive ring (14) are in contact with each other, a guide roller (2) that is freely rotatable in a row in the transport direction is provided. ing. On the other hand, a guide roller (8) which can freely rotate is also provided at a position raised by the height of the glass plate from those positions.

Since the present invention is configured as described above, the drive roller (3) is rotated clockwise by a motor or the like, and the drive roller (4) is rotated in synchronization with the counterclockwise rotation. When the glass plate is inserted from the portion A, as shown in FIG. 4, while being supported by the guide roller (2), the glass plate is sandwiched between the left and right drive rollers and moves in the conveying direction.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. By using a universal joint and a contraction ring, the glass plate is sandwiched and conveyed by two drive rollers, so a reliable and stable gripping force is obtained, and even if the glass plate receives some external force, it gets caught. Stable transportation can be performed without slipping.

Further, even if the thickness of the glass plate changes, there is no gap between the drive ring and the glass plate due to the effect of the contraction ring, and slip does not occur, and the grip force is always kept constant. Therefore, there is no adverse effect due to the thickness of the glass plate and transportation is very stable.

When used for a precision cleaning machine, since there is no drive mechanism on the upper part of the glass plate, there is no generation of particles (fine dust of μm level) due to this, and the particles fall and adhere to the glass plate. It is possible to perform precise and clean cleaning without
