Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a plate glass cutting table used for cutting plate glass.

(Prior Art) Conventionally, in order to cut plate glass, a cut is made along the cutting line of the plate glass using a glass cutter on a cutting table, and then a cutter ruler or the like is used on the back side of the cut. By inserting a bar as a backing material or by moving the plate glass along the table surface and touching the back side of the cut to the edge of the table, both sides of the cut are pressed from above. The plate glass was broken along the cut lines.

(Problem that the invention aims to solve) However, with the method of inserting the backing material into the back side of the plate glass, the work efficiency is poor as the plate glass must be lifted from the table surface each time. In this method, when breaking a plate glass, a separate holding means is required to prevent the divided parts protruding from the table surface from falling to the floor, and in some cases, additional workers are required to do so. Another problem was that these methods required considerable skill to break glass accurately.

Therefore, the technical problem to be solved by this invention is to make it possible to immediately break a plate glass with cuts formed on the table along the cuts while the glass is placed on the table. .

(Means for Solving the Problems) A technical means for solving the above problems is to provide a table surface with a backing material for glass cutting that can be retracted and retracted.

(Function) The backing material is kept in the lowered position until the plate glass is placed on the table surface and the cuts are formed with the glass cutter, so that the backing material does not get in the way.

When breaking a plate glass along the cut line, a guard is made to protrude from the table surface and applied along the back side of the cut line in the plate glass.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4.

A rectangular table plate 3 having a flat table surface 2 is attached to the top of the plate glass cutting table 1, and scale plates 4 are fixedly provided along two adjacent sides of the table surface 2, respectively.

On the other hand, at the bottom of the table board 3, the table board 3
A side plate 6 is attached between each of the legs 5 supporting the four corners of the side plate 6, and among these side plates 6, the other two sides corresponding to the two sides of the table plate 3 to which the scale plate 4 is fixedly attached are attached. A scale plate 7 is fixedly attached to the lower side plate 6 of each.

Support brackets 8 are erected at both ends of these scale plates 4 and 7, and a guide bar 9 is installed between the support brackets 8, and each guide bar 9 has an appropriate number of stops. 10 is fitted. (In FIG. 1, only a single stopper 10 is shown, and other fasteners fitted to each guide bar 9 are omitted.) As shown in FIG. Hole 1
A guide bar 9 is inserted through the stopper 10 so that the guide bar 9 can be slid along the guide bar 9, and by tightening a screw 12, it can be fixed to the guide bar 9 at an appropriate sliding position. The protruding tongue pieces 13 engage grooves of engagement brackets 15 provided at both ends of the cutter ruler 14, thereby fixing both ends of the cutter ruler 14, respectively.

Next, in the transverse direction of the plate glass cutting table 1, three vertical backing members 16 are placed at a predetermined interval.
In the longitudinal direction, two horizontal strips of padding material 17 are inserted at a predetermined distance from each other at a predetermined interval, with the portions intersecting with the padding material 16 being interrupted, respectively, into holes of corresponding shapes provided in the table plate 3. It is set up in a state where The backing members 16 and 17 are moved between a position where their top surfaces slightly protrude above the table surface 2 and a position where their top surfaces are at the same height as the table surface 2, by the mechanism described below. It is said to be able to move up and down.

First, the vertical movement mechanism of the vertical backing member 16 will be explained based on FIG. 2.

A support frame 19 having a running road plate 18 on the upper surface is installed between the side plates 6 provided in the transverse direction of the plate glass cutting table 1 in correspondence with each vertical backing member 16,
On this support frame 19, the running road plate 18
Horizontal moving plate 2 with a plurality of wheels 20 rolling on it
1 is movably placed. Horizontal moving plate 21
There is an operation handle 2 for moving this.
2 are connected via a pin 22a, and the other end of the operating handle 22 passes through a hole 23 in one side plate 6 and extends outward. An engagement protrusion 24 for holding the operation handle 22 in the drawn-out position is provided at the lower opening edge of the hole 23, and a notch formed in the appropriate lower part of the operation handle 22 is provided in the engagement protrusion 24. 25 can be engaged.

Further, a backing material 1 is provided on the upper part of the horizontally movable plate 21.
A support roller 26 supporting the bottom surface of 6 is provided,
These support rollers 26 normally come into contact with recesses 27 provided on the bottom of the backing material 16 to support the material 16 at the same height as the table surface 2, and the horizontally moving plate 21 moves to the left in the figure. When it moves, it escapes from the recess 27 and pushes up the backing material 16. In addition, the above-mentioned support frame 19 and wheels 2
0, horizontal moving plate 21, support roller 26, backing material 1
The side condition of No. 6 is as shown in FIG. 3. In the same figure, the guide members provided on both sides of the horizontally movable plate 21 to prevent the horizontally movable plate 21 from shifting laterally are as follows. Illustrations are omitted.

Next, a mechanism for vertically moving the horizontal backing members 17 will be explained based on FIG. 3.

A support frame 29 that intersects the support frame 19 at right angles is installed between the side plates 6 provided in the longitudinal direction of the plate glass cutting table 1.
9, a horizontally moving plate 32 supported by wheels 31 rolling on the running road plate 30, and a support roller 33 attached to the upper end of the horizontally moving plate 32.
The backing material 17 supported by the vertical backing material 16 and the horizontally movable plate 21 supporting it, respectively
It is divided into a plurality of parts at the intersection. The horizontally movable plates 32 provided separately are the side plates 6 or the horizontally movable plate 2 in the cross direction, respectively.
It is made to a length that allows it to move a predetermined distance in 1 hour,
Further, they are interconnected through a handle 34 penetrated through one side plate 6 and a connecting rod 35a for fixing to a movable rod 35 pivotally connected.
The structure of other points in the vertical movement mechanism of the backing material 17 is the same as the vertical movement mechanism of the vertical backing material 16 as shown in the figure.

The usage conditions and effects of this embodiment configured as described above will be explained next.

As shown in FIGS. 2 and 3, respectively, while holding the backing materials 16 and 17 in a position where their top surfaces are at the same height as the table surface 2, use a glass cutter 36 to cut the table surface 2. Cuts are formed in the plate glass 37 placed on the plate. At this time, the scale plate 4,
7 to fix the cutter ruler 14 along the cutting line of the plate glass 37, and use this to form a straight cut. At this time, if the edge of the scale plate 4 is used as a stopper, positioning of the glass plate 37 becomes easy. If the glass plate 37 is positioned so that the cutting line of the glass plate 37 follows the vertical backing material 16 or the horizontal backing material 17, the glass plate 37 will not have to be moved at all when the glass plate 37 is to be split later. Also good.

After forming the cut in the glass plate 37, remove the cutter ruler 14 from the table plate 3 or move it aside along the guide bar 9. The closest one is made to protrude onto the table surface 2. This operation is performed by pulling out the operating handles 22, 34 corresponding to the pads 16, 17 from the side plate 6. That is, for example, when the vertical backing member 16 is projected onto the table surface 2, when the operating handle 22 is pulled out from the side plate 6, the horizontally moving plate 21 moves to the second position.
As the supporting roller 26 moves to the left in the figure, the support roller 26 escapes from the recess 27 through the inclined surface 28, thereby pushing the backing material 16 upward by a predetermined width, as shown by the imaginary line in FIG. It is. If the notch 25 of the operating handle 22 is engaged with the engagement protrusion 24, the above state is maintained.

The above operation moves the horizontal backing material 17 to the table surface 2.
The upward projection is also carried out in the same manner by pulling the operating handle 34. (Movement in the direction of the arrow shown in FIG. 3) The backing material 16 thus protruding onto the table surface 2
Alternatively, the plate glass 37 can be broken along the cut line by aligning the cut line of the glass plate 37 with the cut line 17 and pressing both sides of the cut line from above.

In addition, as another embodiment of the present invention, the backing member may be formed not in a linear shape, for example, in an arcuate shape. Furthermore, the mechanism for vertically moving the backing material in the present invention is not limited to that of the embodiment described above.

(Effects of the Invention) The present invention has the effect of improving workability because a plate glass with cuts formed on a table board can be immediately broken along the cuts in that state. In addition, it has the effect that even unskilled people can easily work on it.
