Description

Description: TECHNICAL FIELD The present invention relates to a device for aligning two curved glass plates for laminated glass, and particularly to aligning two curved glass plates in a prepolymerized state. For improving a plate aligning device for curved glass for laminated glass.

[Prior Art] Generally, a laminated glass is made by laminating two curved glass sheets with a plastic intermediate film such as a polyvinyl butyral film, and is widely used as a windshield which is a windshield for automobiles from the viewpoint of safety. Has been done.

By the way, in this type of laminated glass, an intermediate film is interposed between two curved glass plates in the laminated glass manufacturing process,
The intermediate film that has eroded from the edges of the two curved glass plates is edge-cut, but it is necessary to align the two curved glass plates in the pre-process of the edge-cutting process of the intermediate film.

Conventionally, as a plate aligning device for curved glass for laminated glass of this type, there is one for aligning two curved glass plates for laminated glass in a polymerized state at a plate alignment stage,
Two curved glass plates are horizontally supported from the bottom side, and the horizontal biaxial X,
A movable support means that can be moved in Y and a stopper that is arranged opposite to one end side of the two curved glass plates in the direction of the one coordinate axis X are provided so that the lower curved glass plate is brought into contact with this stopper. X-direction plate alignment having an X-direction positioning means for driving the movable supporting means and a pressing member arranged at a portion facing the stopper with the two curved plate glasses sandwiched therebetween and for pressing the two curved plate glasses toward the stopper side. And a measuring member for measuring the positions of both end edges of the two curved glass plates in the Y direction of the other coordinate axis, and movable to center the two curved glass plates based on the measurement value of the measuring member. A Y-direction plate aligner having Y-direction positioning means for driving the supporting means and pushing members arranged on both sides of the two curved plate glasses in the Y direction of the other coordinate axis so as to be movable back and forth. Plate aligning drive control for driving and controlling the X-direction positioning means, the X-direction plate aligning means, the Y-direction plate aligning means, and the Y-direction plate aligning means so as to align the curved glass plates with reference to the stopper position and the centering position. Those consisting of means are known.

[Problems to be Solved by the Invention] However, in such a conventional plate aligning device for curved glass for laminated glass, both side edges of the curved glass may be pressed as the pushing member of the Y direction plate aligning means. As long as it is possible, the pushing member is usually configured as one rod-shaped member, and abutted on both side edges of the curved glass plate at one point. Therefore, when the pushing member of the Y-direction plate aligning means is pushed, the pushing load acts only on one point on both side edges of the curved glass plate, and stress concentrates on one point on both side edges of the curved glass plate. There is a problem that both edges of the curved plate glass are easily cracked due to the occurrence of cracks.

The present invention has been made by paying attention to the above problems, and it is possible to effectively avoid the cracking phenomenon at the both side edges of the curved glass sheets that occurs during the plate aligning operation of the two curved glass sheets. A plate aligning device for curved glass for glass is provided.

[Means for Solving the Problems] That is, as shown in FIG. 1, the present invention is an apparatus for aligning two curved glass sheets G1 and G2 for laminated glass in a state of being superposed, Movable supporting means 1 capable of horizontally supporting two curved glass plates G1 and G2 from the lower side and moving in the horizontal two axes X and Y directions on the stage IS, and one of the coordinate axes X.
Has a stopper 2a disposed opposite to one end side of the two curved glass plates G1 and G2 in the direction, and drives the movable supporting means 1 so that at least the lower curved glass plate G1 is brought into contact with the stopper 2a in the X direction. The positioning means 2 and the above-mentioned two curved glass plates G1 and G2 are sandwiched between the upper curved glass plate G2 and the stopper plate 2a, which is disposed in a portion facing the stopper 2a and is displaced from the lower curved glass plate G1 in the X direction. Pressing member
X-direction plate aligning means 3 having 3a, and the other coordinate axis Y
Has a measuring member 4a for measuring the positions of both side edges of the two curved glass plates G1 and G2 in the direction, and is movable to center the two curved glass plates G1 and G2 based on the measurement value by the measuring member 4a. Y-direction positioning means 4 for driving the supporting means 1 and both ends of the curved glass plates G1 and G2 centered by advancing and retracting on both sides of the two curved glass plates G1 and G2 in the Y direction of the other coordinate axis. Y-direction plate aligning means 5 having a pushing member 5a whose edge is pushed by a predetermined amount, and two curved glass plates G1, G2 based on the position of the stopper 2a.
X-direction positioning means 2 and X for aligning the plates in the X-direction.
The direction plate aligning means 3 is drive-controlled, and the Y-direction positioning means 4 and the Y-direction plate aligning means 5 are drive-controlled in order to align the two curved glass plates G1 and G2 in the Y direction with the centering position as a reference. And a pressing means 5a of the Y-direction plate aligning means 5 is constituted by a two-pronged swing arm 7 that abuts on both side edges of the curved glass plates G1, G2 at two points. It is characterized by.

In such a technical means, as the movable supporting means 1, the lower curved glass plate G1 is held by suction or another method, and the upper curved glass plate G1 is placed on the lower curved glass plate G1.
If the G2 is placed and both can be moved integrally, the design may be changed as appropriate. Further, in the laminated glass manufacturing line, the X direction and the Y direction of the movable supporting means 1 can be appropriately selected.

Further, regarding the number of stoppers 2a of the X-direction positioning means 2 and a specific configuration, the stoppers 2a can be freely retracted and retracted so as not to hinder the transportation of the curved glass sheets G1 and G2 in the laminated glass manufacturing line.
Moreover, the design can be changed as appropriate as long as it is the reference position for positioning the curved plate glass in the X direction. In this case, it is necessary to design so that the position of the stopper 2a does not shift even if one end edges of the curved glass plates G1, G2 collide with each other when the stopper 2a advances. An actuator such as an air cylinder can be used as the driving means for moving the movable supporting means 1 in the X direction.

Further, the number and the specific configuration of the pressing members 3a of the X-direction plate aligning means 3 may be appropriately changed as long as the upper curved glass plate G2 is pressed against the stopper 2a in a proper posture.

Furthermore, since the Y direction positioning means 4 has to center the curved glass plates G1 and G2 based on the measurement value information from the measurement member 4a, a servo system is used as the Y direction drive system of the movable supporting means 1. It is necessary to use a combination of a motor and a ball screw with good positional accuracy. In this case, the measuring member 4a may be a measuring bar that directly contacts both side edges of the curved glass plates G1 and G2, or an optical sensor that indirectly detects both side edge positions of the curved glass plate. Etc. may be used.

Further, the pushing member 5a of the Y-direction plate aligning means 5 may be appropriately changed in design as long as it is composed of at least two forked swing arms 7 that come into contact with both side edges of the curved glass plates G1, G2 at two points. It doesn't matter. In this case, from the viewpoint of simplification of the device itself, the pushing member 5a and the measuring member 4a
It is also preferable that the pressing member 5a is also used as a pressing amount, and the pressing amount of the pressing member 5a may be set in advance to a predetermined value, but it is measured from the viewpoint of avoiding excessive pressing operation of the pressing member 5a. It is preferable to variably set the pushing amount of the pushing member 5a according to the measurement value of the member 4a.

Further, as the plate alignment drive control means 6, a curved glass plate is used.
If the plate alignment process of G1 and G2 can be controlled in an appropriate sequence, for example, the X-direction plate alignment process and the Y-direction plate alignment process can be performed at the same time, and the curved glass plates G1 and G2 can be prevented from cracking. Therefore, when the curved plate glass G1, G2 is in contact with the stopper 2a, or when the measuring member 4a or the pressing member 5a is in contact with the curved plate glass G1, G2, a means for preventing overload on the curved plate glass G1, G2 is provided. The design can be changed as appropriate, such as designing.

[Operation] According to the technical means as described above, the lower curved glass plate G1 horizontally supported by the movable supporting means 1 is used for the lower curved glass plate G1 at the stopper 2a position by the X direction positioning means 2. Is positioned with respect to the X direction, and the upper curved glass plate G2 is aligned with the X direction plate aligning means 3 in the X direction with respect to the position of the stopper 2a.

Further, the two curved glass plates G1 and G2 are centered in the Y direction based on the operation of the measuring member 4a of the Y-direction positioning means 4 and then pushed in by the Y-direction plate aligning means 5.
At 5a, the two curved glass plates G1 and G2 are aligned in the Y direction. At this time, the pushing member 5a moves to the forked swinging arm 7
Since the pressing member 5a is made of curved glass G1, G
The pushing load of the pushing member 5a that abuts on both side edges of 2 at two points and acts on both side edges of the curved glass sheets G1, G2 is dispersed at two points.

To control various control devices.

Next, the operation of the plate aligning device for curved glass for laminated glass according to this embodiment will be described with reference to the flowcharts of FIGS. 25 (a) to 25 (c).

Now, as shown in FIGS. 3, 6 and 26 (a), when the two curved glass plates G before plate alignment are carried into the plate alignment stage IS, the control unit 113 causes the position sensor Based on the position information from 110, the two curved glass plates G are aligned with the plate IS
, The lifter 22 is lifted to lift the curved plate glass G by the curvature-developing rods 36 and 37, and in this state, the control unit 113 operates the lifting cylinder 34,
The lower curved glass plate G1 is suction-held by the chuck member 35 of the suction chuck 30 (steps 1 to 3).

After that, as shown in FIG.
After erecting the stopper 41, the positioning air cylinder 43 in the X direction is driven to press the curved glass plate G toward the stopper 41 (steps 4 and 5). At this time,
For example, when the lower curved plate glass G1 is arranged so as to project from the upper curved plate glass G2 to the stopper 41 side, only the lower raw plate curved glass G1 is brought into contact with the stopper 41 and positioned.

Next, when the brake valve 111 of the positioning air cylinder 43 is turned on, the control unit 113 gives a high speed command as a speed mode to the measurement and pushing member 60, and
As shown in FIG. 26 (c), the measuring and pushing member 60 is moved at high speed from the coordinate positions (L0, R0) of the left and right reference points (step 6). At this time, the push-driving air cylinder 67 of the measurement / push-in member 60 is in an operating state, and the measurement / push-in member 60 is used for measurement.
Then, as shown in FIG. 16, the measuring and pushing member 60 is
Is brought into contact with the switch bar 72 of the speed changeover switch 71, and the limit switch 73 is turned on, the control unit 113 gives a signal for changing the speed of the measurement / pushing member 60 to a low speed and a current limit command to the AC servomotor 81. (Step
7,8).

Then, as shown in FIG. 27, the measuring and pushing member 60 causes one end of the swing arm 63 to contact the side edge of the curved glass G, and then swings to perform the curved glass G. The two-pivoting arm 63 is stopped in a state where the two-pivoting arm 63 is brought into contact with the side edge of the at two points. At this time, since the measuring / pushing member 60 does not abut against the side edge of the curved glass G at a high speed, there is no risk of the side edge of the curved glass G being unnecessarily cracked, and the AC servo motor 81
Since the current limit command is given to the side plate, the high load does not continuously act on the side edge of the curved plate glass G.

After that, the control unit 113 waits for the time until the measuring / pushing member 60 comes into contact with the side edge of the curved glass G with a timer, and then the coordinate values (L, R) at the current position of the measuring / pushing member 60. ) Is read based on the signal from the encoder 86 (steps 9 and 10). Then, the control unit 113 calculates the movement amount (L-L0, R-R0) from the left and right reference points, and determines whether the difference between the left and right movement amounts is within the allowable error δ (for example, ± 0.2 mm). Is determined (steps 11 and 12).

If the amount of lateral movement of the measuring / pushing member 60 is larger than the allowable error δ, the control section 113 sends a drive command to the AC servo motor 52 of the Y-direction positioning drive system 51, and 26 As shown in FIG.
= {(L-L0)-(R-R0)} / 2 is moved (step 13), and steps 10 to 12 are repeated until the lateral movement amount of the measuring / pushing member 60 is within the allowable error δ. Repeat.

When the left and right movement amount of the measuring / pushing member 60 falls within the allowable error δ, the curved glass plate G is centered in the Y direction, as shown by a virtual line in FIG. 26 (d).

After that, the control unit 113 returns the driving air cylinder 67, gives a movement command to the AC servomotor 81, moves the measurement and pushing member 60 by a predetermined amount, and then turns on the braking means 90 (step 14,15,16). Then, as shown in FIG. 26 (e), each pair of brake pads 96 restrains one brake plate 91, and the pair of measurement / push-in members 60 keeps the interval between them at a constant l. It is supported so that it can move relative to it. Then, the control unit 113 includes the push-in drive air cylinder 67 and the rotary actuator.
A pushing drive command is given to 46 to start the pushing operation of the measurement / pushing member 60 and the pushing operation of the X-direction pusher 45 (steps 17 and 18).

At this time, the measuring / pushing member 60 pushes the side edge of the curved glass G by bringing the swing arm 63 into contact with the side edge of the curved glass G at two points as shown in FIG. Since the pushing load F at that time acts on the side edge of the curved plate glass G in a state of being dispersed at two points, a part of the side edge of the curved plate glass G is hardly broken due to stress concentration.

Also, looking at the pushing operation of the measurement and pushing member 60,
One measuring and pushing member 60 abuts the lower curved glass G1 fixed to the suction chuck 30, and the other measuring and pushing member 60
Will collide with the upper curved glass G2. At this time,
Both measuring and pushing members 60 can move relative to each other at a constant interval l, so that one measuring and pushing member 60 is lower curved glass.
It does not abut against G1 unnecessarily strongly, and the other measuring and pushing member 60 surely pushes the side edge of the upper curved glass plate G2. Thereby, the curved plate glass G is aligned in the Y direction.

When the plates are aligned in the Y direction, the upper curved glass G2
May shift in the X direction, but the upper curved glass G2 is X
It is pressed to the stopper 41 side by the direction pressure 45,
At this stage, the curved glass sheets G are aligned in the X direction.

Thereafter, the control unit 113 turns off the braking means 90 (step 19), and determines whether or not the plate alignment of the curved plate glass G is completed in steps 20 to 23 (steps 10 to 13).
If it is determined that the plate alignment is completed, the stopper 41, the suction chuck 30, the lifter 22 and the like are returned to the initial positions, and the plate alignment process is finally ended (step 24). .

[Effects of the Invention] As described above, according to the curved plate glass plate aligning device for laminated glass according to the present invention, when the curved plate glasses are aligned in the superposed state, the pushing member of the Y-direction plate aligning means is used. The indentation load on both side edges of the curved plate glass was dispersed by devising the above-mentioned method, so that the acting stress due to the indentation load on both side edges of the curved sheet glass becomes small, and the bending stress based on the stress concentration is correspondingly reduced. It is possible to effectively prevent cracks at both side edges of the sheet glass.

Further, according to the curved plate glass plate aligning device for laminated glass of claim 2, since the pushing member of the Y-direction plate aligning means is also used as the measuring member, it is not necessary to separately provide the measuring member. Therefore, the structure of the plate aligning device can be simplified accordingly.

Furthermore, according to the curved plate glass plate aligning device for laminated glass of claim 3, the pressing members can be moved relative to each other while the spacing between the pair of pressing members is kept constant during plate alignment in the Y direction. , Even if the pressing member is pressed against one side edge of the fixed lower curved glass plate more than necessary, while the pressing member escapes to the lower curved glass plate, the upper curved glass plate is securely aligned in the plate alignment direction. It is possible to push the plate into the plate, and the plate alignment ability can be further improved while the crack of the curved plate glass is effectively prevented.
