Description

[0001] SHEET GLASS MATERIAL DIVIDING DEVICE [0002]

The present invention relates to a cutting apparatus for obtaining a thin plate glass having a predetermined dimension by dividing a width direction end portion of a thin plate glass material formed into a plate shape.

BACKGROUND ART Conventionally, a thin plate glass (referred to as "thin plate glass" in the specification and claims in the claims) is used for a display glass or a cover glass for various electronic apparatuses.

A float method and a fusion method are generally employed as the manufacturing method of such a thin plate glass. In the float process, a glass raw material is supplied to a float bath filled with molten tin, and a glass raw material floating on the molten tin is formed into a plate shape. On the other hand, in the fusion method, the glass raw material is supplied to the fusion pipe, and the overflowed glass raw material in this fusion pipe is drawn into a plate shape while being pulled downward. The thin plate glass material formed by such a manufacturing method is formed of, for example, a thin plate having a thickness of 1 mm or less.

Then, the thin plate glass material formed into a plate shape by such a manufacturing method is divided into a predetermined length dimension, and then end portions in both width directions are divided to become a thin plate glass having a predetermined width dimension. In this specification and claims, the thin film glass is conveyed in the "longitudinal direction ", and the direction orthogonal to the conveying direction is defined as the" width direction ".

As such prior art, there has been proposed a method in which a ribbon-shaped thin plate glass manufactured by the float method is provided with a row of broken wire, the inside of the line of the row is supported by a supporting roller, the outside of the line is pressed downward by the breaking roller, (Edge portion) (width direction end portion) of the breaking roller is provided with a pair of supporting rollers for supporting the outside of the breaking roller from below.

Japanese Patent Application Laid-Open No. 2009-102204

However, in the thin plate glass material formed by the float method or the fusion method described above, a portion where the thickness is unstable (hereinafter referred to as "bead portion ") is generated in the widthwise end portion. Therefore, in the invention described in the above-mentioned Patent Document 1, the width direction end portion is supported by the supporting rollers from below while being cut from the upper side by the breaking roller and is removed.

However, in the apparatus described in Patent Document 1, the thin plate glass is supported from the lower side by the supporting roller and the lower supporting roller, and the upper roller is pressed from above by the pressing roller to cut the end in the width direction , It is difficult to cleanly cut the end edge. Moreover, since the sheet glass material is transported and cut from above, it is likely that the ends in the width direction come into contact with the product to be scratched.

Further, the apparatus described in Patent Document 1 can be applied to a case where the thin plate glass is cut while conveying the thin plate glass like the thin plate glass formed by the float method. However, like the thin plate glass material formed by the fusion method, , It is impossible to apply the present invention to a case where the end portion in the width direction of the thin plate glass material whose longitudinal direction is cut to a predetermined dimension is divided at a predetermined position by forming a large bead portion (water-hardened portion) at the lower end.

In recent years, there has been a demand for a thinner glass plate, and a breaking apparatus capable of stably dividing a bead portion formed at an end of the thin glass plate to obtain a thin plate glass of a predetermined size is desired.

Accordingly, it is an object of the present invention to provide a cutting apparatus capable of stably dividing a glass end portion including a bead portion, even if a thin plate glass having a bead portion at an end portion thereof, can obtain a thin plate glass having a predetermined dimension.

In order to solve this problem, the present invention provides a conveyor comprising a conveyor for supporting a predetermined length of a thin plate glass material from below and arranging the thin plate glass material at a predetermined position, and a glass material end in the width direction of the thin plate glass material arranged at a predetermined position of the conveyor A retraction roller capable of being displaced in a state of being supported at the lower side and a retraction roller capable of being displaced in a state of being retracted outward in the width direction and a retraction roller which is retained at an inner position and an outer position of the division line formed in the conveying direction at the width- And a scribe having a cutter for forming a dividing line of a predetermined depth on the upper surface of the thin plate glass at a position opposite to the cutting table at a position below the cut line for supporting the division line position of the thin plate glass disposed on the conveyor from below, And a cutter of the scribe machine is retracted upward, A division group, a frit end groups divided the division of dividing the material ends in the division line, the evacuation by the evacuation roller to the outside in the width direction and a discharger for discharging downwards.

With this configuration, in the state where the thin plate glass material is arranged at a predetermined position of the conveyor, the divided end position of the glass end portion in the width direction is supported at the lower side in the cutting direction, and at the same time, When the cutter is retracted and the end portion in the width direction of the thin plate glass material is divided downward in the division line with the cutting base as a fulcrum, The glass end portion including the bead portion formed at the end portion of the thin plate glass material whose direction is cut to a predetermined dimension is divided downward to obtain a thin plate glass having a predetermined dimension. In addition, since the glass end portion is bent in the plate thickness direction in the division line, the end edge can be cleanly divided. In addition, by separating the glass end portion in the width direction by the cutter and then retracting the retraction roller outward in the width direction, the glass end portion including the bead portions at the both end portions can be discharged downward without contacting the product portion.

The dividing device may be configured to retract the cutter of the scribing device upward and to push up the cutting platform to divide the glass end portion of the thin plate glass material in the dividing line.

With this configuration, the cutter can be retracted upward and the cutter bar can be pushed up so that the cutter end can be divided downward with the cutter as a fulcrum.

In addition, the dividing device retracts the cutter of the scribing device upward, retracts the retraction roller outward in the width direction, presses the retainer holding the thin plate glass at a position outside the dividing line, And the glass end portion of the ash is divided.

With this configuration, the glass end portion can be divided downward with the cutter stand as a point by retracting the cutter upward and pushing the end portion in the width direction by the retention roller and the retainer at the widthwise outer position.

The cutter and the cutter may be configured to be adjustable in the width direction of the thin plate glass.

With this configuration, it is possible to adjust the dimension in the width direction of the thin plate glass material that becomes the product by adjusting the dimension for dividing the end portion of the thin plate glass material.

The cutter may have a concave portion whose upper end is formed in an arc shape and extends in the carrying direction and which is wider than the blade thickness of the cutter in the longitudinal direction of the head portion.

With this configuration, when the division line is formed on the thin plate glass with the cutter, the cutter carries the division line on the thin plate glass material along the concave portion of the cut base so that the top surface of the cutting base is not damaged by the blade of the cutter when inserting the division line .

And a pressing member for pressing the thin plate glass material downward at an inner position and an outer position of the dividing line, the pressing member being disposed at a position apart from the dividing bar at a position spaced outward from the cutting table And an upper surface pressing member provided on the upper surface.

With this configuration, the cutter cut with the dividing line is retreated to the thin plate glass material, and then the thin plate glass material is pushed up as it is cut, the thin plate glass material pushed downward by the pushing member can be easily divided in the dividing line.

The upper surface pressing member may be provided with a pressing portion that presses a plurality of longitudinal portions of the thin plate glass material at points.

With this configuration, damage to the surface of the thin plate glass as a product can be suppressed to the utmost by using a plurality of points that contact the surface (also referred to as "A side") of the thin plate glass.

And a pressing member for pressing the thin plate glass material downward at an inner position and an outer position of the dividing line, the pressing member being disposed at a position apart from the dividing bar at a position spaced outward from the cutting table And a suction member for sucking the thin plate glass material downward.

As shown in Fig. The rotary shaft 84 is provided with a plurality of support shafts 85 projecting in one direction and a roller member 82 is provided at the tip of the support shaft 85, respectively. The rotary shaft 84 is rotatable by a drive motor 86.

9, the retraction roller 81 rotates the rotary shaft 84 of the drive motor 86 to rotate the roller member 82 in the lower surface of the thin plate glass 1, State and the retracted state retracted to the outside in the width direction at the lower surface of the thin plate glass material 1 can be displaced to the displacement angle alpha. The displacement angle alpha is set at an angle at which the glass end portion 2 that discharges downwardly does not contact the roller member 82, as will be described later.

As shown in Fig. 10, the upper surface pressing member 71 is provided in the scribe device 50. [0064] As shown in Fig. The upper surface pressing member 71 is supported from above on a driving motor 74 provided at the lower end of a support leg 73 extending downward from the guide unit 60 of the scribing machine 50. The drive motor 74 may be a cylinder or the like. The upper surface pressing member 71 has a supporting member 75 having a front and rear part supported by the driving motor 74 and a plurality of contact members 76 protruding downward from the supporting member 75. The contact member 76 is in contact with the upper surface of the thin plate glass 1 in a small area. By making the contact member 76 contact with a small area, the area of the structure contacting the upper surface of the thin plate glass 1 is minimized. A cushioning member 77 is provided at a portion of the contact member 76 which is in contact with the thin plate glass material 1. The upper surface of the thin plate glass material 1 is prevented from being scratched by providing the cushion material 77. [ As the cushion material 77, a resin material, a rubber material, or the like is used.

The upper surface pressing member 71 moves the support member 75 horizontally up and down by driving the drive motor 74 synchronously. Therefore, all the contact members 76 can be raised and lowered horizontally through the support member 75 by driving the drive motor 74.

11 shows the cutter 52 of the cutter 30 and the scribing device 50 and the cutter 52 of the belt conveyor 21 of the conveyor 20 and the upper surface pressing member 71 of the retainer 70 The positional relationship of the contact member 76 and the roller member 82 in the separation roller 41 of the separator 40 (Fig. 7) and the retraction roller 81 of the discharger 80 (Fig. 8) have. In the drawing, only the left side from the center line C of the dividing device 10 is shown.

The cutter 30 and the cutter 52 are disposed so as to face each other in a direction perpendicular to the pass line P as shown in Fig. Similarly, the contact member 76 in the upper belt pressing member 71 of the retainer 70 and the inner belt conveyor 21 of the conveyor 20 are also opposed to each other in the direction perpendicular to the pass line P . The division bar 41 of the divider 40 and the roller member 82 of the retraction roller 81 are also in the same positional relationship.

As described above, the cutter 52, the upper surface pressing member 71 and the dividing bar 41 are lowered toward the upper surface of the thin plate glass material 1 located on the pass line P or retracted upward from the upper surface, . The cutter 30 is retracted downward from the pass line P and is in contact with the lower surface of the thin plate glass material 1 of the pass line P, So that the thin plate glass 1 can be displaced in a state of being divided at the division line L (Fig. 12).

Next, with reference to Fig. 12 and Figs. 13A to 13D, the glass end portion 2 in the width direction in the thin plate glass material 1 by the cutting apparatus 10 constructed as described above is divided Flow is explained.

First, as shown in Fig. 12, the thin plate glass material 1 cut to have a predetermined dimension in the longitudinal direction at the upstream side is conveyed. A division line L is formed at both end portions in the width direction with respect to the thin plate glass material 1. [ Then, the thin glass sheet 5 of a predetermined size is obtained by dividing the glass end portion 2 including the bead portion B in the dividing line L in the longitudinal direction (indicated by a dot-dash line). Hereinafter, the flow of dividing the glass end portion 2 of the thin plate glass 1 will be described.

First, as shown in Fig. 13A, the thin plate glass material 1 conveyed upstream is placed at a predetermined position by the belt conveyor 21 of the conveyer 20. Fig.

Next, as shown in Fig. 13B, the cutter 30 is lifted from the lower surface of the thin plate glass material 1. Fig. The upper surface pressing member 71 is lowered so that the thin plate glass material 1 is held between the belt conveyor 21 and the dividing bar 41 is lowered, (1) is maintained.

13B, an example is shown in which the thin plate glass material 1 is held by sucking the thin plate glass material 1 toward the belt conveyor 21 by the suction member 72 instead of the upper surface pressing member 71, as described above. If the suction member 72 is provided instead of the upper surface pressing member 71, the glass end portion 2 is separated from the upper surface (A side) of the thin plate glass material 5 as a product without contacting the structure And the cleanliness of the A side can be maintained.

In this state, the cutter 52 of the scribing device 50 is lowered and comes into contact with the thin plate glass material 1. [ Then, the cutter 52 is sent from the scribing device 50 in the transport direction W to form a division line L on the upper surface of the thin plate glass 1 (FIG. 12).

Next, as shown in Fig. 13C, the cutter 52 of the scribe machine 50 is retracted upward. The cutter base 30 is pushed up and the glass end portion 2 including the bead portion is divided along the division line L with the cutter 30 as a point. Even if there is a large bead portion B (Fig. 12) in the glass end portion 2 of the thin plate glass material 1 at the time of such division, the central portion in the width direction of the thin plate glass material 1 is sandwiched between the belt conveyor 21 and the upper surface Since the glass end portion 2 is held in the vertical direction by the pressing member 71 and the glass end portion 2 is held in the vertical direction by the retraction roller 81 and the division bar 41, can do. It is also possible to carry out the work quickly if the retraction of the cutter 52 and the push-up of the cutter 30 are performed almost simultaneously at a slight time difference.

Then, as shown in Fig. 13D, the retraction roller 81 is rotated toward the outside, and the glass end portion 2 including the bead portion is discharged downward.

The cutter 30 is lowered and the upper surface pressing member 71 and the dividing bar 41 are raised so that the retraction roller 81 supports the thin plate glass material 1 Return. Then, the thin plate glass 5, in which the glass end portion 2 is divided at a predetermined dimension, is taken out and the next thin plate glass material 1 is carried in. Hereinafter, the above operation is repeated.

As described above, according to the above-described cutting apparatus 10, even if a large bead portion is formed at the end portion like the thin plate glass material 1 formed by the fusion method, the glass end portion including the bead portion can be stably divided It is possible to stably carry out the operation of dividing the thin plate glass material 1 into a desired size.

The division line L formed on the thin plate glass 1 is pushed upward from below by the cutter 30 so that the glass end portion 2 is separated from the division line L in the width direction outward And the divided glass end portion 2 is discharged downward, so that the divided end portion of the thin glass plate 5, which is a product, can be divided so as not to damage the end portion.

The example shown in Figs. 14A and 14B is an example in which the glass end portion 2 is divided in a flow different from Figs. 13C and 13D. 13A and 13B are performed in the same manner, the description thereof will be omitted.

13B, after the dividing line L is formed on the upper surface of the thin plate glass 1 with the scribing machine 50, the cutter 52 of the scribing machine 50 The separating bar 81 holding the outside of the dividing line of the thin plate glass material 1 between the evacuating roller 81 and the evacuating roller 81 while retracting the evacuating roller 81 outward in the width direction, Press down.

As shown in FIG. 14B, the glass end portion 2 including the bead portion is divided along the division line L with the cutter base 30 as a point as the division bar 41 is pressed down. The divided glass end portion 2 is discharged downward.

Next, the upper surface pressing member 71 and the dividing bar 41 are raised, and the retraction roller 81 is returned to a state supporting the thin plate glass material 1. [ Then, the thin plate glass 5, in which the glass end portion 2 is divided at a predetermined dimension, is taken out and the next thin plate glass material 1 is carried in. Hereinafter, the above operation is repeated.

Therefore, even in this example, even if there is a large bead portion B (Fig. 12) in the glass end portion 2 of the thin plate glass material 1, the central portion in the width direction of the thin plate glass material 1 is conveyed to the belt conveyor 21 The glass end portion 2 is divided by the cutter base 30 in a state of being held in the vertical direction by the upper surface pressing member 71 so that the glass end portion 2 is stably divided along the line of departure L can do. It is also possible to perform a quick operation by allowing the cutter 52 to be retracted, the retraction roller 81 to be retracted, and the breaking bar 41 to be pressed down substantially at the same time with a slight time difference.

The glass end portion 2 is divided along the division line L formed on the thin plate glass material 1 so as to be separated from the widthwise outer side with the cutter 30 as a fulcrum, (2) is discharged downward, it can be divided so as not to damage the divided portion of the thin plate glass (5) as a product.

In the above embodiment, the glass end portion 2 of the thin glass plate 1 is divided. However, by adjusting the position of the conveyor 20 and the scribing unit 50 in the width direction, It is also possible to correspond to the frit 1, but the present invention is not limited to the above embodiment.

Although a drive motor (servo motor) is described as an example of the drive unit in the above embodiment, it is sufficient that the structure can be precisely controlled even if other structures are used, and the structure of the drive unit is not limited to the above embodiment.

Though the thin plate glass material 1 formed by the fusion method has mainly been described in the above embodiment, the production method of the thin plate glass material 1 is not particularly limited.

It should be noted that the above-described embodiments are merely examples, and various modifications are possible without departing from the gist of the present invention, and the present invention is not limited to the above embodiments.

The thin plate glass cutting apparatus according to the present invention can be used when a large bead portion, which may be generated when a thin plate glass is manufactured, is divided into thin plate glass of a predetermined size as in the fusion method.
