Description

The present invention relates to a scribing device for forming a cutting scribe line (scribing groove) around a peripheral wall surface (side wall surface) of a three-dimensional glass molded into a convex shape from a glass plate.
After the scribe line is formed by the scribe device of the present invention, the convex three-dimensional glass product divided along the scribe line has an upper surface and a peripheral wall. Such convex three-dimensional glass can be used as an exterior cover that covers the surface of the other article and its edge by, for example, fitting another article into the inner recess of the convex three-dimensional glass, It can be used as a three-dimensional cover glass that covers a board or the like.

  Conventionally, in order to decorate or protect the surface of an article, a thin glass plate is pasted as an exterior cover. However, as shown in FIG. 7, the end surface of the glass plate 21 attached to the surface of the article 20 is exposed to the outside and is unnatural, or liquid enters the gap between the frames, so that the frame material 22 and the like Therefore, it was necessary to cover the end surface of the glass plate 21, and the work was troublesome. Therefore, as shown in FIG. 4, an inverted flat plate-like glass (convex three-dimensional glass) exterior cover having a flat planar portion (top surface) 23 having a flat rectangular shape and a peripheral wall 24 connected to the flat planar portion 23 is created. Can be considered.

  In the case of manufacturing the above-described inverted flat dish-shaped exterior cover from a glass plate, as shown in FIG. 5, a planar rectangular convex portion (convex three-dimensional glass) composed of a flat top surface 25 and a peripheral wall surface 26 connected thereto. 27), and is formed by separating the upper portion from the middle of the peripheral wall surface 26 of the convex three-dimensional glass 27.

  In order to mold the convex three-dimensional glass 27 on the flat glass plate W, for example, it can be performed by a method as disclosed in Patent Document 1 or Patent Document 2. FIG. 8 is a diagram schematically showing a conventional molding method including these documents. A molding die 30 having a molding recess (chamber) 29 is disposed in the heating furnace 28, a glass plate W is disposed so as to cover the opening of the molding recess 29, and the space in the molding recess 29 is vacuum pumped 31. Thus, the glass plate W heated and softened in the heating furnace is molded along the surface of the concave portion 29 for molding by sucking through the duct 32 and the suction hole 33 to be a negative pressure.

  The convex three-dimensional glass 27 formed by such a manufacturing method requires a process for separating the upper portion from the middle of the peripheral wall surface 26 of the convex three-dimensional glass 27.

  As a general method for dividing flat glass, a flat glass is placed on a horizontal flat table and a scribe line is formed by rolling while pressing a cutter wheel, and then the glass plate is cut from the scribe line. There are a method (for example, Patent Document 3) and a method for holding a glass plate on a vertical table and forming a scribe groove with a cutter wheel on the vertically standing glass plate (for example, Patent Document 4). However, a method for forming a scribe line along a three-dimensional peripheral wall such as the convex three-dimensional glass 27 has not been studied so far.

Japanese Patent Laid-Open No. 04-275930 JP 2007-131475 A JP 09-202635 A JP 2001-302264 A

Unlike flat glass, when forming a scribe line by a cutter wheel on the peripheral wall surface of convex three-dimensional glass, it is difficult to use the scribe method that has been employed for flat glass as it is.
In other words, in the general method for dividing flat glass with a cutter wheel, the glass plate to be processed is received by the table on the opposite surface against which the cutter wheel is pressed. It can be easily controlled to a high pressure (when the pressing force is too small, a scribe line is not formed, and when it is too strong, it breaks randomly).
However, when the peripheral wall of the convex three-dimensional glass is scribed directly with a cutter wheel, the peripheral wall is a three-dimensional object, and since the opposite surface that presses the cutter wheel is a space, it is very difficult to control the pressing force of the cutter wheel. It is difficult to form an appropriate scribe line.
In particular, when scribing with a cutter wheel so that it circulates around the entire circumference of a rectangular peripheral wall surface, the positional relationship between the cutter wheel and the peripheral wall changes rapidly in the corner portion, so it could not be processed easily. .

  Then, this invention solves the said subject and aims at providing the scribe apparatus which can be formed so that the scribe line for a division | segmentation may be circulated on the surrounding wall surface of the convex-shaped solid glass shape | molded by the glass plate. And

  The scribing device of the present invention made to solve the above problems is formed so as to circulate a scribe line for cutting on a peripheral wall surface of a convex three-dimensional glass having an upper surface and a peripheral wall surface molded from a glass plate. A scribing device for holding a glass plate on which the convex three-dimensional glass is formed in a horizontal posture and rotating around a vertical axis as a fulcrum, and a peripheral wall surface of the convex three-dimensional glass It has a cutter wheel formed so as to be urged by a pressing force for forming a scribe line on the outer surface, and capable of moving forward and backward in the contact direction, and a peripheral wall surface having the same shape as the peripheral wall surface. In addition, a copying jig that rotates around a vertical axis as a fulcrum, and a copying that is elastically in contact with the peripheral wall surface of the copying jig and that can move forward and backward in the contact direction. The rotary table and the copying jig move synchronously and are formed to rotate in the same direction at the same speed, and the copying roller is accompanied by the rotation of the copying jig. The cutter wheel is formed so as to move back and forth following the fluctuation of the contact position with the peripheral surface of the copying jig, and the cutter wheel is configured to move back and forth in conjunction with the movement of the copying roller. .

  Since the scribing device of the present invention is configured as described above, the movement of the copying roller is achieved by rotating the rotating table on which the glass plate is placed and the copying jig synchronously and in the same direction at the same speed. The scribe line that goes around the convex peripheral wall of the glass plate is properly moved by moving back and forth while pressing with an almost constant pressing force set between the cutter wheel and the peripheral wall of the glass plate. A scribe line can be formed with certain pressure. Even when the convex 3D glass is square and the corner is formed, the corner is detected by the copying roller and moved in conjunction with this movement, so that it follows the sudden change at the corner of the 3D convex glass. be able to.

In the present invention, the copying roller and the cutter wheel are preferably held by a common fixture.
Accordingly, the cutter wheel can be accurately moved following the movement of the copying roller, and the assembly configuration can be simplified.

  Hereinafter, the details of the scribing apparatus according to the present invention will be described in detail with reference to the drawings showing embodiments thereof. FIG. 1 is a perspective view showing a characteristic part of a scribing apparatus according to an embodiment of the present invention, FIG. 2 is a front view showing a part of the scribing apparatus in cross section, and FIG. 3 is a copy of the scribing apparatus. It is a figure for demonstrating a motion of a roller and a copying jig.

  The scribing apparatus A is a horizontal plate for holding a glass plate W on which a convex three-dimensional glass 27 (see FIG. 5) formed of a flat top surface 25 (upper surface) and a peripheral wall surface 26 connected thereto is horizontally held. A rotary table 1 is provided. The turntable 1 is formed so as to be rotated by a vertical shaft 2 provided at the center of the lower surface and a drive source 3, and a holding means for holding the glass plate W at a fixed position on the surface of the turntable 1, for example, A large number of small air suction holes (not shown) for adsorption are provided.

  A cutter wheel 4 for forming a scribe line along the circumferential direction is provided on the outer surface of the peripheral wall surface 26 (in the convex three-dimensional glass 27) of the glass plate W. The cutter wheel 4 is held by the cutter head 4a and is brought into contact with the peripheral wall surface 26 with a constant pressing force capable of forming a scribe line by a pressing mechanism (spring mechanism) provided inside the cutter head 4a. Is formed. Further, the cutter wheel 4 is provided on the machine frame 8 of the scribing device A via the fixture 5, the support arm 6 and the traveling unit 7 so that the cutter wheel 4 can move forward and backward with respect to the contact direction (vertical direction of the plate surface). A horizontal rail 9 is movably supported.

  Further, a copying jig 11 having a peripheral wall surface 10 having the same shape as the peripheral wall surface 26 of the convex three-dimensional glass 27 is disposed immediately above the turntable 1. The copying jig 11 is suspended from the machine frame 8 so as to be rotatable by a vertical shaft 12 provided at the center of the upper surface and a drive source 13. The drive source 3 and the drive source 13 are driven in synchronization.

  Further, a copying roller 14 is provided that elastically contacts the peripheral wall surface 10 of the copying jig 11 and moves in the circumferential direction along the peripheral wall surface. The copying roller 14 is held by a roller head 14a, and is attached to a fixture 5 common to the cutter head 4a so as to be able to advance and retreat in the contact direction. Further, the support arm 6 connected to the fixture 5 is provided with a cylinder 15 that urges the copying roller 14 with a certain elasticity in the contact direction. The cylinder 15 can be replaced with a spring.

Next, the operation of the scribing apparatus A will be described.
First, after placing the glass plate W including the convex three-dimensional glass 27 on the rotary table 1 so as to be aligned with the copying jig 11, the supporting arm 6 is moved and the copying roller 14 moves the copying jig 11. The position which contacts the surrounding wall surface 10 and the position where the cutter wheel 4 contacts the surrounding wall surface 26 of the convex three-dimensional glass 27 of a glass plate are moved. Thereafter, the rotary table 1 and the copying jig 11 are rotated in the same direction at the same speed and synchronously via the respective drive sources 3 and 13.

  FIG. 3 is an explanatory plan view showing the movement of the copying roller 14 and the copying jig 11 due to rotation. When the copying jig 11 is rotated clockwise (may be in the reverse direction) from the starting position of FIG. 3A with the shaft 12 as a fulcrum, the copying roller 14 is copied as shown in FIG. 3B. The tool 11 is pushed back by the peripheral wall surface 10. When the maximum retracted position shown in FIG. 3C is passed, the advancing along the peripheral wall surface 10 of the copying jig 11 reaches the position shown in FIG. When the copying jig 11 further rotates, the same operation as described above is performed to return to the starting position in FIG.

  On the other hand, the cutter wheel 4 performs the same operation as the copying roller 14 in conjunction with the copying roller 14. That is, since the cutter wheel 4 is supported by the fixture 5 common to the copying roller 14, the copying roller 14 shown in FIG. 3 is replaced with the cutter wheel 4, and the copying jig 11 is replaced with a convex three-dimensional glass 27 of a glass plate. The same movement as above is performed. Since the positional relationship between the cutter wheel 4 and the convex three-dimensional glass 27 moves forward and backward depending on the positional relationship between the copying jig 11 and the copying roller 14, scribing can be performed with a substantially constant pressing force. Thereby, the scribe line S (refer FIG. 1) which goes around the surrounding wall surface 26 of the convex three-dimensional glass 27 can be processed with an appropriate pressing force.

  Thereafter, the glass plate W is transported to the breaking device, and the upper part of the convex portion is cut off from the scribe line S, and a flat planar portion (top surface) 23 having a planar rectangular shape as shown in FIG. An inverted flat dish-shaped outer cover having 24 can be obtained.

  In the above embodiment, it is preferable that the copying roller 14 and the cutter wheel 4 can be adjusted to appropriate positions so that the mounting position can be changed with respect to the fixture 5.

  Further, in the present invention, the copying jig 11 does not necessarily have to be disposed immediately above the turntable 1 as in the above embodiment. For example, as shown in FIG. 6, the copying jig 11 is arranged with its position shifted laterally from directly above the turntable 1, and the copying roller 14 that contacts the peripheral wall surface 10 of the copying jig 11 and the glass plate W By holding the cutter wheel 4 in contact with the convex peripheral wall surface 26 with the bent common fixture 5, the same copying operation as described above can be performed.

  Further, in the present embodiment, one convex three-dimensional glass 27 is processed for one copying jig 11, but rotation for placing the convex three-dimensional glass 27 on one copying jig 11. As shown in FIG. 6, a plurality of tables 1 are arranged at different positions, and a plurality of cutter wheels 4 for scribing the peripheral wall surface 26 of the convex three-dimensional glass 27 placed on each rotary table 1 are used in common with the copying roller 14. If it hold | maintains by 5, the some convex-shaped three-dimensional glass 27 can also be processed simultaneously.

Although typical examples of the present invention have been described above, the present invention is not necessarily limited to the above-described embodiments. The present invention achieves its purpose and appropriately modifies and changes within the scope of the claims. It is possible.
For example, in the above embodiment, the top surface 23 (see FIG. 4) is a square planar shape, but it may be circular or elliptical, or may be a three-dimensional curved surface.
Moreover, although the turntable which mounts convex three-dimensional glass was made into the plane, it was set as the turntable which has a table convex part which matched the inner shape of the convex part of convex three-dimensional glass, and a convex three-dimensional glass is covered on a table convex part. It may be processed in a fixed state.

  The scribing apparatus of the present invention can be used for forming a scribe line for cutting around a peripheral wall surface of a cubic convex portion formed on a flat glass plate.
