[Problems to be Solved by the Invention] Japanese Patent Publication No. 55-395
In the publication No. 11, the target thin plate material is flat, and when the thin plate material is raised, the push-up member comes into contact with the inner surface of the thin plate material, so that the inner surface of the thin plate material is easily soiled or damaged. In addition, when applied to a curved glass plate such as a window glass for a vehicle, the effect of air appears because the glass plate is curved even if it is received by the edge when standing up and does not contact the inner surface side. Instead, the edge of the glass is rubbed by the pushing member, so that the edge is damaged or dust is generated, and the dust is rather blown to contaminate the inner surface of the glass plate.

Japanese Patent Application No. 5-132 relating to the invention of the present applicant
In No. 01, the tilting arm is used when the curved glass plate carried in with the convex side facing downward in the horizontal posture is erected by the tilting arm.
Since the glass plate reinforced by rolling on the caster roller on the film did not have the problem of scratches and the like, it satisfied the purpose sufficiently, but the glass plate before inserting the laminated glass film For scratches, stains, etc., all of the above devices were installed at the end of the transfer line, and in order to visually inspect the curved glass plate at the side of the transfer line in the middle of the transfer line. However, there is a problem in that there is no structure in which the inspector can change the direction so that it can be easily inspected and can be tilted.

[0005]

In order to solve the above problems, the present invention provides a device for swiveling and tilting a curved glass plate carried in a horizontal posture with a convex surface facing upward by a transport mechanism. A glass support frame to which a receiving member that abuts a curved glass plate at its edge is fixed, and a curved glass plate on the receiving member that is fixed to the glass supporting frame are fixed to one end side of the glass supporting frame. And a pressing means of a glass plate which is sandwiched and fixed by a reciprocating pressing member provided on the other end side, an elevating means for elevating and lowering the glass support frame, and a swivel for converting the glass support frame by 90 degrees in the horizontal direction. Means and a raising and lowering means for raising and lowering the glass plate by raising the pressing member side with the center axis at a position slightly closer to the stopper than the central portion of the glass support frame, and the glass. The pressing member in the pressing means for pressing the glass plate on the holding frame to the stopper position, the receiving member fixed on the glass supporting frame, and the stopper are urethane rubbers having a rubber hardness of about 90. Provided is a curved glass sheet swiveling and raising / lowering device, which is provided with a position correcting means for causing a curved glass sheet supported by a receiving member to travel in a conveying direction together with an elevating means, a swiveling means, and a raising / lowering means.

[0006]

In the production of laminated glass for vehicles, the visual inspection after washing and drying of the raw glass sheet and the insertion of the interlayer film between the two glass sheets are carried out in the clean room, but a pair of curved sheets is used. The glass plates are carried into the visual inspection position in the clean room in a horizontal position with the convex side facing upward and the large side (outside the car) glass plate and the small side (inside the car) glass plate in that order. It is transferred from the transport frame to the glass supporting fixed frame.

The curved glass plate on the glass supporting and fixing frame is taken up and raised by the elevating means by the glass supporting frame in the horizontal state, and the edge of one side of the glass sheet is pressed by the pressing member of the pressing means. , The curved glass plate is slid to the stopper position on the other end side, and the curved glass plate is sandwiched between the pressing member and the stopper. Next, while the curved glass plate is being held, the glass support frame is rotated 90 degrees by the rotating means so that the stopper side on the glass support frame becomes the inspector side, and at the same time as the rotating operation, or for a little time. The glass support frame is tilted by a tilting means with a delay. After the completion of tilting, the pressing member is retracted.

After the completion of the inspection, the curved glass plate is transferred from the receiving member onto the glass supporting fixed frame by the raising / lowering means, the turning means, and the elevating means, and is carried out, but returned to the horizontal state from the raising / lowering state. The curved glass plate shifts to the downstream side by the amount of movement of the glass on the glass support frame with respect to the conveying direction by the pressing means, so the shift amount can be corrected by the position correcting means as necessary in the subsequent step. .

Since the receiving member, the stopper and the pressing member which are fixed on the glass supporting frame are made of a material which easily slides and generates little abrasion dust, the glass surface can be prevented from being contaminated by dust and the pressing member can be pressed. Since the swiveling operation is performed while the glass plate is sandwiched by the means, the glass plate is not displaced or damaged during the swiveling operation, and the glass plate slides during the tilting operation and the glass plate slides when it comes into contact with the stopper. It is possible to prevent the generation of defective products without damaging the edges, and it is possible to improve the tact time.

The operation of the present invention will be described below. In the manufacturing process of laminated glass for vehicles, if dust or dirt adheres to the curved glass plate that becomes the base plate when inserting the interlayer film, it will be a defective product such as non-standard because of quality, so a visual inspection of the glass plate and 2 sheets Inserting the interlayer film between the glass plates of the clean
In order to prevent the generation of dust, the pair of curved glass plates after the cleaning and drying of the curved glass plates, which are the base plates, are mounted on the large side (outside the car) with the convex surface facing upward. Clear the plate and the small side (inside the car) glass plate in a horizontal position in this order.
It is carried into the visual inspection position in the room, and is transferred from the glass transport frame 50 onto the glass support fixed frame 51 by pitch feed by a lift and carry type transport device (not shown). The curved glass plate G on the glass supporting and fixing frame 51 is supported by four edges, and the long side of the substantially trapezoidal shape faces the downstream side.

A lifting cylinder 1 provided on the traveling frame 1.

By the operation of 37, the pressing member 39 advances to press one edge of the curved glass plate G, slide the curved glass plate G until the stopper 34 abuts the curved glass plate G, and the curved glass plate G stops. Even if the pressing cylinder 37 presses against -34, an unreasonable force is not applied to the curved glass plate G, and the pressing force of the pressing cylinder 37 prevents the curved glass plate G from being deformed. The air pressure is adjusted, and the curved glass plate G is sandwiched between the pressing member 39 and the stopper 34.

By fixing the receiving member 32 made of urethane rubber or the like having a rubber hardness of about 90 to the upper surface of the glass supporting frame 28, smooth movement of the curved glass plate G by the pressing means 40 is caused, and dust is generated by the sliding movement. Also, since the stopper 34 and the pressing member 39 are made of hard rubber, the edge of the glass plate G is not damaged.

Next, with the curved glass plate G sandwiched, the glass support frame 28 is horizontally moved by the turning means 24 so that the stopper 34 side on the glass support frame 28 faces the inspector side.
In order to make a 0 degree turn, the turning cylinder 21 is operated and the forward movement of the turning cylinder rod 22 causes the turning lever 23 axially attached to the tip of the turning cylinder rod 22 as shown in FIG.
Swivels about the swivel axis and changes the linear movement of the swiveling cylinder rod 22 into a rotational movement about the swivel axis.

Next, the raising and lowering means 41, which operates simultaneously with the turning operation or with a slight time delay, raises and lowers the glass support frame 28 by raising and lowering the tilting frame 25 on the upper end of the turning shaft 19. The lower end is fixed, and the upper end of the tilting frame 25 is rotatably mounted on the tilting rotation shaft 29 via a bearing.
The raising and lowering movement of 8 is carried out by the forward and backward movement of the raising and lowering cylinder rod 30 by the operation of the raising and lowering cylinder whose one end is fixed. The lever 31 rotates the tilting rotary shaft 29 to tilt the glass supporting frame 28 around the tilting rotary shaft 29. The tilt angle α is preferably about 60 to 80 degrees as an angle suitable for visual inspection of the curved glass plate G, but of course is not limited to this angle and may be changed as necessary. Further, in this embodiment, the tilting cylinder rod 30 is used.
A tilt lever 31 provided at the tip of the tilt lever 31 is directly connected and fixed to the tilt rotation shaft 29 to rotate the tilt rotation shaft 29, but the tip end of the tilt cylinder rod 30 and both sides of the glass support frame 28 are provided. Alternatively, the glass supporting frame 28 may be directly pushed up by connecting to the frame.

After the raising / lowering operation is completed, the pressing member 39 is retracted by the backward movement operation of the pressing cylinder 37, the curved glass plate G held between them is released, and the visual inspection can be performed. After the inspection is completed, when an inspection completion signal is input to a control device (not shown) using a foot switch or the like, first, the pressing means 40 is pressed.
The curved glass sheet G is held by the return to a horizontal state a curved glass sheet G by raisably means 41 at pivot means 24 90
The degree direction is changed and the long side of the substantially trapezoidal curved glass plate G is directed to the downstream side, and the pressing cylinder 37 is double-moved to release the sandwiched glass plate G. The position is corrected by the running frame.

A traveling base 8 screwed on a ball nut 7 screwed with
The stop position can be freely set by the position correcting means 10 which is slidable along the traveling rail 3 and can freely reciprocate in the carrying direction, and the setting input can be made according to the size of the glass plate G or the like. Incidentally, the pulse signal from the encoder is controlled by counting to stop the running motor.

The curved glass plate G in the horizontal state shifts to the downstream side by an amount corresponding to the movement of the glass plate G by the pressing member 39 of the pressing means 40 on the glass support frame 28 with respect to the conveying direction. If necessary, the displaced position can be corrected by the position correcting means 10 . In addition, when the curved glass plate G is turned upside down, there is an obstacle in the periphery of the conveyor, the curved glass plate G contacts the obstacle, and it is difficult to arrange the lighting device necessary for visual inspection. Even if there is a problem, the position correcting means 10 may move the necessary amount in the carrying direction.

The receiving member 32, the stopper 34, and the pressing member 39 fixed on the glass supporting frame 28 are made of a material that is easily slidable and produces little abrasion dust, such as rubber hardness 9.
Since a hard urethane rubber of about 0 is used, the glass plate G
It is possible to prevent the glass surface from being soiled by dust generated by the contact with the edge of the glass plate G, and the pressing means 40 can be used for the glass plate G.
Since the swiveling operation is performed while holding the glass plate, the glass plate G is not displaced or damaged during the swiveling operation, and the glass plate G slides during the tilting operation and the edge of the glass plate G is contacted with the stopper. It is possible to prevent defective products from being damaged and to improve tact time.

The receiving member 32 may be fixed to the glass supporting frame 28 by an adhesive agent, a screw, a bolt or the like. Also, the lifting means 17 , the turning means 24 , the raising and lowering means
