Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a plate glass positioning device, and more particularly to a curved plate glass positioning device.

(Prior Art) The plate glass processing consists of a number of steps, and the positioning of the plate glass sent on a conveyor line requires a high degree of accuracy as automation has progressed in recent years. It is attached to every process such as marking.

As its prior art, two belt conveyors for transferring sheet glass, two stop rollers provided at the front in the transfer direction, and two pressing rollers are mounted so as to be able to move up and down, and are arranged in the traveling direction of the belt conveyor. A plate aligning device for laminated glass comprising a moving table provided so as to move forward and backward, and two aligning tables equipped with contact rollers that move forward and backward by the same amount in a direction intersecting with a traveling direction of the belt conveyor in a horizontal plane, A table is placed continuously on the glass plate transfer line, and a brush conveyor is provided on this table so that it can move forward and backward, and the moving direction of the brush conveyor is reversed when the glass plate to be transferred contacts the table. A limit switch for stopping and a stopper for stopping the glass plate moving in the direction opposite to the conveying direction due to the work of this switch are provided. Further, there is known a device for positioning the glass plate by a pusher that moves in a direction intersecting with the conveying direction while the glass plate moves in the opposite direction to the conveying direction (for example, Japanese Patent Publication No. 54-21846). Gazette, see Jitsukō Sho 62-2187).

(Problems to be solved by the invention) In the above technique, the former is that the conveying plate glass is abutted and stopped by the stop roller, and the pressing roller which is continuously raised advances to the advancing side of the plate glass to press the plate glass and align the front and rear of the plate glass. After that, the contact roller pushes forward from the left and right to move and correct the plate glass to perform positioning, but since a stop roller is used, a hard surface roller may cause chipping during collision, When positioning a curved sheet glass, when the sheet glass is moved and adjusted while contacting each roller, the height position of the contact portion changes momentarily with the movement, and the edge of the sheet glass moves up and down on the circumferential surface of the roller due to the pressing force. However, with soft rubber rollers, etc., there is a problem that the edge of the sheet glass is damaged by the generation of unreasonable stress such as the edge of the sheet glass biting into the surface. The latter uses a brush conveyor to prevent the glass from chipping by buffering the impact force of the stopper and pusher at the time of collision with the plate glass, but position correction is performed by placing the plate glass on the brush, It is easy to glide. However, in the case of curved glass, there is a drawback that the glass cannot be conveyed and accurately positioned because the glass surface partially comes into contact with the conveying roller, brush and the like.

(Means for Solving Problems) The present invention has been made for the purpose of improving the above-mentioned problems of the prior art, and includes an elevating stand for supporting plate glass conveyed by two belt conveyors by a free roller. And a means for adjusting the positions of the long and short two sides of the plate glass with a roll,
Arranging a pressing means for pressing the end edge of the plate glass with a roll through a cylinder at a position facing the moving means.
Rolls of the pressing means and the in-and-out means are vertically movably inserted via a spring on a vertical axis, and a coil spring is installed in a connecting portion for inserting and connecting with a rod of the cylinder to buffer when the roller is pressed. It is to provide a positioning device for a plate glass.

The flat glass used in the present invention is a flat glass positioning device for all flat glass having a closed curved shape to curved ones.

(Operation) To explain the operation based on the configuration of the present invention, the plate glass conveyed by the two belt conveyors is stopped on the elevating stand, and the movable roller arranged on the stand is moved up by the elevating stand. The lower surface of the plate glass is supported, and the rolls by the access means move forward from the two sides of the long and short sides one by one, moving forward while contacting the edge of the plate glass to the specified position, and the roll by the pressing means continues from the other long side. The edge of the sheet glass is contact-pressed, and finally the pressing means arranged on the short side operates the roll to press the edge of the sheet glass on the short side, and the sheet glass is sandwiched and positioned by the facing rolls. .

Then, even if the roll of the access means collides with the edge of the plate glass which is free on the free roller, it moves on the free roller without giving an impact, and the long / short 2
The plate glass whose side positioning is regulated moves while being in contact with the roll peripheral surface by the operation of the pressing means, but the change in the height of the edge of the curved plate glass due to the movement changes to the roll inserted through the spring. It can move up and down freely, and the roll itself also rotates freely.In addition, the pressing force is buffered by the operation of the coil spring installed in the connecting part, and the stress generated at the edge of the plate glass is relaxed by these actions. is there.

Next, when the cylinder 7 of the long side loading / unloading means 4 that is suspended on the conveyors 2 and 2 operates to push the rod 6 to the stroke end and move the metal fitting 9, the metal base 9 is axially fixed to the metal fitting 9. Reference numerals 10 and 10 also indicate the long-side reference points of the plate glass 1, and the plate glass 1 moves on the free roller by colliding with the roll. Then, when the cylinder 49 of the short side loading / unloading means 41 is operated and the piston rod 50 is pushed out to the stroke end, the roll base 47 is also interlocked with the guides 45, 45.
Roll table that moves along conveyors to the conveyors 2 and 2 and slides
When the reference roll 52 erected at 47 collides with the edge of the glass sheet 1, the glass sheet 1 moves on the free rollers 21, 21, 21 ', 21'.

Subsequently, when the cylinder 30 of the long side pressing means 23 is operated and the piston rod 31 is housed in the cylinder, the table 27 connected to the piston rod 31 is also moved to follow the metal plate 37 on the table 27. Adjusting roll 38 installed upright through
Is in contact with the edge of the plate glass 1, but is rotatable around the pin 36 and the end face of the metal plate 37 and the stopper bolts 40, 40.
The adjustment rolls 38, 38 slightly swing to the left and right depending on the distance between the adjustment rolls 38, 38 and the adjustment rolls 38, 38 reliably contact the edge of the sheet glass, thereby distributing the pressing load to two points and operating the cylinder 30. Press the edge of the sheet glass with. Base roll
The long side of the glass is sandwiched between 10, 10 and the adjusting rolls 38, 38, but the pressing force of the plate glass 1 due to the operation of the cylinder 30 causes the spring 33 to be inserted into the rod 31 in the connecting portion 32 of the table 27. Is buffered by the action of, and the impact force acting on the edge is relaxed. Next, the cylinder 58 of the short side access means 42
Is activated to push out the rod 59, and the roll base 56 that interlocks with the rod 59 moves along the guide rods 54, 54,
The pressing roll 65 standing upright on the 56 collides with the short side of the plate glass 1, and the pressing force acts on the edge of the plate glass 1 by the operation of the cylinder 58, so that the plate glass 1 is sandwiched.
0, 10 and the adjusting rolls 38, 38 move while being in contact with each other, but the spring 12 of each roll absorbs the displacement of the height of the curved edge caused by the movement, and the end face of the glass sheet 1 is rotated by each rotation. It moves without invading the surface of the rolls 10, 38, 52, 65 and without sliding on the surface. Since the pressing force of the pressing roll 65 at the time of collision acts after being buffered by the spring 63 attached to the connecting portion 61 attached to the roll base 56, the impact force on the edge is small.

When the four long and short sides of the plate glass 1 are sandwiched, after being supported by another moving device, for example, a suction pad (not shown), each moving means,
The operation of the pressing means is released, and the process is moved to the next step, and then the elevating / lowering platform 16 descends to wait for the next plate glass.

The operation of each cylinder operates according to a sequence control in which it is controlled according to a predetermined order. Moreover, the positioning of the flat glass 1 having different sizes and shapes is performed by each reversible motor 2
Operate 8, 48, 57, move the base 26, roll base 47, 56 in advance and fix it, adjust the standby position of each roll 38, 38, 52, 65. It goes without saying that it can be used for positioning flat glass.

(Effect of the Invention) In the present invention, the plate glass is supported in a free state on the free roller on the elevating stand, and then the positions of the long and short sides of the plate glass are adjusted by the reference rolls, and then the other two sides are sequentially arranged. The pressing roll is used to perform positioning by adjusting the pressing movement, but the contact between the pressing roll and the edge of the plate glass relieves the impact force via the spring, and the positioning movement of the plate glass while being clamped by the roll is
Although it causes vertical displacement of the edge of the sheet glass, it is relaxed by the spring combined with the roll and does not generate unreasonable stress on the edge of the sheet glass, not only achieving accurate positioning, but also for changing the dimension of the sheet glass to be processed. Can be easily dealt with, and has a practically remarkable effect such as breakage of the plate glass during collision.
