Hereinafter, the present invention will be described based on illustrated embodiments.
FIG. 1 shows the invention according to claims 1 and 2, that is, a building or the like to be dismantled as a means for supporting the support 7 of the suction pad 6 so that the position of the glass cutting operation can be moved and the cut glass pieces can be transported. 1 shows an embodiment in which a work vehicle 3 (small passenger crawler heavy machine) moving on a floor 2 is used in use. Reference numeral 4 denotes a glass plate to be cut and disassembled.
Four suction pads 6 (not limited to this number) adsorbed to the glass plate 4 to be cut and disassembled correspond to approximately the apexes of a square as shown in an enlarged manner in FIG. The suction pads 6 are supported on the back by a substantially cross-shaped support body 7 when viewed from the front.

The support 7 of the suction pad 6 is also provided with an arm 8 that rotates substantially parallel to the plate surface of the glass plate 4 around a support shaft that protrudes from the center of the support 7 in the back direction. Yes. A guide rail 9 is supported on the distal end of the arm 8 in a substantially perpendicular arrangement. Further, among the support shafts protruding in the back direction of the support body 7, a rear portion further than the position of the arm 8 is attached to and supported by the distal end portion of the steerable arm 5 of the work vehicle 3. In the case of the illustrated example, the steerable arm 5 has a plurality of joint portions, for example, like a drive arm of a shovel car, and is configured to steer the joint portions with a plurality of hydraulic cylinders or pneumatic cylinders. ing. Therefore, the support 7 is moved in position, direction and movement by the steering control (operation by the operator) of the steering arm 5 of the work vehicle 3 together with the suction pad 6 and the arm 8 and the guide rail 9 at the tip thereof. Can be done freely. Furthermore, the rotation and positioning means of the arm 8 can be remotely controlled by meshing the pinion of the drive motor 16 that takes a reaction force on the support side of the steerable arm 5 and the turning gear of the arm 8. It is configured.
In the embodiment shown in FIGS. 3 and 5, the guide rail 9 supported by the arm 8 is linear. When the glass plate 4 to be cut and disassembled is a rectangle, the guide rail 9 is slightly shorter than the short side (the vertical side in the illustrated example) of the glass plate 4 and is ½ of the long side (the horizontal side). As for the length, the glass plate 4 described later is cut and disassembled more efficiently.

  As shown in FIG. 2, a traveling block 10 having a plurality of track type rollers moving along the guide rail 9 is movably mounted on the guide rail 9. Since the specific configuration and the traveling and positioning function of the traveling block 10 are already known and well known as an overhead crane, a trolley mechanism, and the like, the detailed description thereof is omitted. Reference numeral 11 in the figure indicates a traveling motor of the traveling block 10. Therefore, the traveling block 10 moves on the guide rail 9 to an arbitrary desired position by driving control of the traveling motor 11, and determines the position of the cutting operation of the glass plate 4 by the disk cutter 12 for glass cutting described later. Further, remote control for proceeding with the cutting operation can be performed.

  A disk cutter 12 for cutting glass is installed on the upper surface of the traveling block 10. In the case of the illustrated example, the disk cutter 12 is configured to be directly connected to the rotation shaft of the drive motor 13. The drive motor 13 is supported at the tip of the turning arm 14, and the base end portion of the turning arm 14 is attached to the rotation shaft of the turning motor 15. Therefore, the disk cutter 12 is set close to the glass plate 4 by the drive control of the turning motor 15 as shown by an arc arrow cd in FIG. After cutting and at the time of non-cutting, it is possible to remotely control the turning operation of retreating away from the glass plate.

  Although not specifically shown in the figure, the suction pad 6 is vacuum suctioned by a vacuum pump and means for automatically controlling the vacuum release (vacuum circuit control), and the arm 8 Means for remotely controlling rotation and positioning through control of the drive motor 16, means for remotely controlling movement and positioning of the travel block 10 through drive control of the travel motor 11, and cutting work by the disk cutter 12 for glass. The means for performing remote control through the drive control of the turning motor 15 is configured to be controllable by providing a control panel or the like at the driver's seat of the work vehicle 3. Therefore, the operator located in the driver's seat of the work vehicle 3 can perform all remote control of the cutting device by one person while sitting in the driver's seat.

Next, a method and work contents for cutting and breaking the glass plate 4 using the above-described cutting device for breaking the glass plate will be described mainly with reference to FIG.
The operator of the work vehicle 3 brings the work vehicle 3 close to a position appropriate for the dismantling work with respect to the glass plate 4 to be disassembled, and then positions the steerable arm 5 of the work vehicle 3. The suction pad 6 is sucked to an appropriate place for cutting and cutting the glass plate 4 by the control, and the glass plate 4 is firmly fixed and supported. Then, the arm 8 is rotated to perform cutting positioning, and the traveling block 10 is moved to the start position on the guide rail 9 in advance. Subsequently, the glass disk cutter 12 is rotated and brought close to the cutting position, and the glass block 4 is cut to a depth necessary for cutting the glass plate 4, and the traveling block 10 is directly cut in the cutting direction on the guide rail 9 in a predetermined glass cutting speed. Go on. When the traveling block 10 has finished moving forward to the advance limit position on the guide rail 9, the disk cutter 12 is retracted (retracted and swung) from the glass plate 4 and released to temporarily stop the cutting operation. Is moved backward to the limit position on the guide rail 9. If appropriate, the arm 8 is rotated to change the cutting direction of the travel block 10 and the guide rail 9. Alternatively, the suction pad 6 is once pulled away from the glass plate 4 and moved to an appropriate place for the next cutting and cutting (see the dotted arrow in FIG. 5) and sucked to an appropriate position again, so that the cutting operation can be continued. To. Thereafter, the cutting operation of the glass plate 4 by the glass disk cutter 12 is resumed, and the cutting line is continued and extended.

Incidentally, as shown in FIG. 5, the cutting work in the case of cutting a piece of glass having a similar shape (quadrangle) as large as possible from the quadrangular glass plate 4 and disassembling is performed, for example, using the point a on the upper side indicated in FIG. The method of proceeding around the circuit as indicated by the arrows and finally proceeding to cut from point b to point a is convenient for stable support and cutting of a heavy glass plate. .
As apparent from FIG. 5, by combining the guide rail 9 in a straight state and the rotation of the arm 8 that supports the guide rail 9, not only a square but also a triangular or polygonal glass piece can be easily cut and cut. is there. Alternatively, when the guide rail 9 is configured to have an appropriate curvature, a circular or elliptical shape can be easily cut.

Next, a cutting apparatus for breaking glass sheets according to the inventions described in claims 1 and 3 will be described based on the embodiment shown in FIG.
In the present embodiment, as a means 30 for supporting the support 7 of the suction pad 6 so as to move the position of the cutting operation and transport the cut glass piece, a beam 20 such as a building to be dismantled or a column (if shown). The gantry 31 is temporarily fixed to (not shown), and the like. The gantry 31 includes a guide rail 32 attached to the gantry 31 and an arm block 33 that travels along the guide rail 32. The arm block 33 is similar to the traveling block 10 of the first embodiment in that the arm block 33 travels along the guide rail 32, and is already known and well-known as an overhead crane or a trolley mechanism. Description is omitted.

The arm block 33 has a plurality of joints as in the case of the shovel car drive arm, and is a free arm that is easy to control by steering the joints with a plurality of hydraulic cylinders or pneumatic cylinders. 34 is provided. The support 7 and the arm 8 of the suction pad 6, the guide rail 9 and the travel block 10, and the glass cutter 12 for glass cutting are supported on the distal end portion of the universal arm 34 in the same configuration as in the first embodiment. ing.
However, in the case of the present embodiment, unlike the work vehicle 3 of the first embodiment, there is no operator's driver's seat, so the suction pad 6 suction and release means, the arm 8 rotation and positioning control means, Means for controlling the movement and positioning of the travel block 10, means for controlling the drive of the glass disk cutter 12, etc. are each located in the vicinity of the arm block 33, together with the controller of the arm block 33, or a separate controller (operation panel). ) Prepare as.

  The method for cutting and cutting the glass plate 4 by the glass plate dismantling and cutting apparatus of the present embodiment is substantially the same as in the first embodiment. Since there is no passenger-type work vehicle, the operation method and work method are equivalent to the operation of an overhead crane through the controller from the ground.

  Although the present invention has been described based on the illustrated embodiments, of course, the present invention is not limited to the above-described embodiments. As long as it does not deviate from the object and the gist of the present invention, and the technical idea, it should be noted that the present invention can be carried out in a wide variety of ways, including design changes, applications, and modifications as required by those skilled in the art.
