Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting laminated glass or plate glass such as glass having protective films on both sides.

[0002]

2. Description of the Related Art Conventionally, a laminated glass in which a film 2 for coloring is interposed between two plate glasses 1 as shown in FIG. 4 or a protective film 3 for protecting the plate surfaces on both sides as shown in FIG. In the case of the former, in order to cut the attached sheet glass 1, after putting a cutting line on the sheet glass 1 on one side, the laminated glass is inverted and a cutting line is placed on the remaining sheet glass 1 on one side.

In the latter case, the protective film 3 on one side is cut to form a cutting line on one side of the glass sheet 1, and then the glass sheet 1 is reversed to cut the remaining protective film 3 on one side to the remaining one surface of the glass sheet 1. Insert a cutting line.

Incidentally, the work of inserting the cutting line may be performed manually or mechanically.

[0005]

According to the above-mentioned work procedure, since the plate glass is inverted and the cut is made,
When manually performed, it takes time to position the ruler so that the front notch is completely aligned with the rear notch.When using a machine, if there is even a small protrusion on the edge of the plate glass, the edge of the plate glass will be attached to the ruler. The front notch and the rear notch do not completely coincide with each other even when pressed, and when the notch which is not parallel to the edge of the sheet glass is made, the notch cannot be made by the machine.

If both cuts do not completely match,
The cut surface of the sheet glass is not a right angle with respect to the sheet surface of the sheet glass, and thus is a defective product.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet glass cutting device which is capable of making a perfectly matched cut on both sides of a laminated glass or both sides of a laminated glass without inverting the sheet glass.

[0008]

In order to solve the above-mentioned problems, the present invention provides a table on which laminated glass or flat glass having a protective film on both sides is placed, and a laminated glass or flat glass on the table is appropriately selected. Along the surface of the laminated glass or plate glass placed on the table and the receiving member provided to receive the upper surface of the laminated glass or plate glass that has stopped moving up while being stopped by the means for horizontal movement. A traveling body that is reciprocally movable, an elevating member that elevates and lowers on the traveling body, and a cutter that is provided so as to make a notch on a line that coincides with the upward and downward ends of the elevating member. It employs a plate glass cutting device.

[0009]

First, laminated glass or flat glass having protective films on both sides is placed on a table.

Next, the cutter is lowered together with the lifting body, and while the traveling member is running, a cut is made on one plate glass surface of the laminated glass by the cutter, and a protective film is cut by the cutter, and a cut is made on one side of the plate glass. Put in.

After that, while raising the cut laminated glass by appropriate means, the laminated glass is received by the lower surface of the receiving member, and the cutter is raised together with the elevating body while maintaining the receiving state, and then the traveling body is run. While making the cut, make a notch on the other plate glass surface of the laminated glass with a cutter, and cut a protective film with the cutter to make a cut on the other face of the plate glass.
