Description

[Detailed explanation of the idea] The present invention relates to a glass plate processing machine.

The glass plate grinding machine according to the present invention, for example, grips a glass plate horizontally on both sides of the plate, and grinds the end faces, or edges, of both sides in parallel while conveying it along a straight line. Process. That is, the glass plate processing machine according to the present invention adjusts the position of the glass plate as it is fed into the main conveyor device that linearly conveys the glass plate along the linear conveyance line of the main conveyor device. It has a regulating device.

By the way, the glass plate regulating device of the conventional glass plate processing machine is located at the front of the main conveyor device.
That is, it has a structure in which rotary rollers are simply arranged linearly along both sides of the glass plate on the upstream side in the conveyance direction of the glass plate. In this structure where rotating rollers are simply arranged, the glass plate must be manually placed against the roller row, and the glass plate itself cannot be automatically aligned along a straight line.

Moreover, the glass plate cannot be automatically carried into the main conveyor device only by these left and right roller rows, ie, both sides, and it is necessary to manually push the glass plate.

As described above, the conventional regulating device that regulates the position of the glass plate using a simple row of rotating rollers requires manual operation and is inefficient.

The glass plate 20 is conveyed while being held between the support conveyor 4 and the pressure conveyor 5 from the top and bottom directions in FIG. 2, respectively.

On the other hand, the grinding head 3 is equipped with a spindle and a processing wheel, and is located outside the main conveyor device 2.
That is, the glass plate 20 protruding left and right in FIG.
The main body 1 is equipped with a device for grinding the edges of the machine.

50 is a glass plate regulating device that regulates the position of the glass plate 20. This glass plate regulating device 50 is installed in the front part of the main body 1, that is, in the upstream position in the conveyance direction of the glass plate, with respect to the main conveyor device 2. This glass plate regulating device 5
0 is arranged on one side of the main conveyor apparatus, and a belt conveyor apparatus 6 that provides a reference line for the glass plate 20 to be carried in, and a main conveyor apparatus 2 facing this belt conveyor apparatus 6.
A roller conveyor device group 7 arranged on the other side of
Thus, the roller conveyor group 7 is configured to press the glass plate 20 against the belt conveyor device 6.

That is, the roller conveyor device group 7 elastically contacts one of the opposing end surfaces of the glass plate 20 to be processed, and cooperates with the belt conveyor device 6 to position the glass plate 20 at a predetermined position. They are arranged in a line along the conveying direction of the glass plate, facing the belt conveyor device 6.

The belt conveyor device 6 is provided with a belt 8 that is in contact with one of the opposite end surfaces of the glass plate 20, and an inner side of the belt 8 that is opposite to the side that is in contact with the end surface of the glass plate 20. The belt 8 is provided with a regulation plate 9 that supports and regulates the belt 8 in order to provide the belt 8, and a frame 11 on which the regulation plate 9 and a pulley 10, which will be described later, are mounted. The frame 11 is attached to the front portion of the main conveyor device 2 in the conveyance direction of the glass plate 20 and on one side of the main conveyor device 2 .

To explain the belt conveyor device 6 in more detail, the first
As shown in FIGS. 2 and 4, first, on the upper surface of the frame 11, which is arranged in the shape of the cross section in FIG. In FIG. 2, a long regulating plate 9 whose cross section is arranged in a shape is attached to the main conveyor device 2 so as to be adjustable and movable along the conveyance direction of the glass plate 20, that is, along a straight line. Toothed pulleys 10A and 10B constituting the pulley 10 are installed before and after the regulating plate 9 in the transport direction of the glass plate 20, and the regulating plate 9
A toothed belt 8 is wound around the toothed pulleys 10A and 10B. That is, the belt conveyor device 6 carries the glass plate 20 to be processed.
The glass plate 20 is conveyed and driven by contacting the other one of the opposing end faces of the glass plate 20 .

The toothed pulley 10A disposed at the rear of the regulation plate 9 in the transport direction is a drive pulley, and
As shown in FIG. 4, a gearbox device 12 attached to the lower surface of the main conveyor device 2 is connected to the shaft of the tail drum of the main conveyor device 2 via a chain or the like. The belt conveyor device 6 is driven by power transmitted from the main conveyor device 2 to the chain, gearbox device 12, and pulley 10A in this order. Note that 13 is a tension pulley that applies a predetermined tension to the belt 8.

On the other hand, the roller conveyor device group 7 has a
A plurality of roller conveyor devices 15 are arranged in a straight line.

Each of these roller conveyor devices 15 is shown in FIG.
As shown in FIGS. 2 and 3, the frame 14
Rotating body 16 mounted horizontally rotatably on the top surface of
A roller member 18 is connected to one end of the rotating part 17, which is the center point of rotation, and a frame 14 is connected to the opposite end of the rotating part 17 via a spring 19 as an elastic member. There is. The roller member 18 is configured so that the elasticity of a spring 19 acts on it.

That is, each roller conveyor device 15 can rotate in one plane that includes the surface of the glass plate 20, and one end thereof is located at a point in the conveying direction of the glass plate 20 compared to the center point of the rotation. A rotary body 16 configured to be located in front, and a rotary body 16 configured to be in contact with the other end surface of the glass plate 20 and rotatable around an axis disposed in a direction orthogonal to the one plane. It consists of a roller member 18 attached to one end of the roller member 18, and a spring 19 attached to the rotating body 16 to elastically press the roller member 18 against the other end surface. Incidentally, the belt conveyor device 6 and the roller conveyor device group 7 constitute the glass plate regulating device 5.

According to the glass plate processing machine configured as described above, the belt 8 supported by the regulation plate 9 of the belt conveyor device 6 in the glass plate regulation device 5
By aligning the line with the straight line along the conveyance direction of the main conveyor device 2, the belt conveyor device 6 and the roller conveyor device group 7
When the glass plate 20 is sandwiched between the two, the glass plate 20 is automatically conveyed to the main conveyor device 2 while being regulated by the belt line, that is, the reference line. In other words, the glass plate 20 moves linearly on a line that coincides with the straight line of the main conveyor device 2 and is carried in. For this reason, the lines of the opposing edges of the glass plate 20 are ground in parallel.

Since it has the above-mentioned novel configuration, the glass plate processing machine of the present invention is capable of transporting a glass plate to be processed by sandwiching it between the belt conveyor device and a plurality of roller conveyor devices to position it at a predetermined position. In this case, the elastic member moves the glass through the roller member attached to one end of the rotating body, which is located forward in the conveying direction of the glass plate compared to the center point of rotation of the rotating body. Since the end face of the plate can be elastically pressed, when a glass plate having, for example, a rectangular shape to be conveyed is introduced between the belt conveyor device and the plurality of roller conveyor devices, the corner of the glass plate is Even if it comes into contact with the roller member, the rotating body can absorb the impact force due to the contact with the roller member by rotating around the center point of rotation, in other words, the corner of the glass plate It is possible to reduce the impact caused by the contact of the roller member over the area, prevent the corners of the glass plate from being chipped or damaged, and reduce the incidence of defects in the glass plate to be processed.
