Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically fitting beads to the peripheral edge of a glass plate.

[0002]

2. Description of the Related Art As shown in FIG. 9, a general structure of a sliding door in which a glass plate is fitted is such that a bead (glazing channel) 100 made of synthetic rubber or the like is fitted around the periphery of a glass plate G, and the bead 100 is attached. Through aluminum sash 10
The glass plate G is held at the position 1.

To fit the above-mentioned bead 100 to the glass plate G, the bead 100 is cut to a length equal to the peripheral length of the glass plate G, one end of this bead is fitted to a part of the peripheral edge of the glass plate, and then the glass plate G is fitted. The bead is fitted by a method such as rotating the glass plate G, and finally both ends of the bead are abutted and continuous.

[0004]

As described above, in the conventional case, the bead length is made equal to the peripheral length of the glass plate G so that both ends of the bead are continuous after fitting.
However, since the beads are made of synthetic rubber,
After a long time (several months) after fitting, the bead contracts with time, and a gap is generated between both ends of the bead. If a gap is created, rainwater will invade from this portion.

[0005]

In order to solve the above problems, the present invention is designed to make the length of a bead supplied from a bead supply device longer than the entire circumference of a glass plate by the amount of shrinkage of the bead over time. I chose

[0006]

When the bead is fitted with the glass plate vertical, the glass plate is vertically moved in the vertical plane to fit the bead on one side edge, and then the glass plate is rotated 90 ° to move the other. If the bead is also fitted to the side edge and the bead is fitted to the entire circumference in this way, the end of the bead protruding by the leveling roller is forcibly fitted.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an overall view of a system used for carrying out a bead fitting method according to the present invention. In the figure, 10 is a bead fitting robot and 30 is a bead supply device.

The bead fitting robot 10 is a glass plate G.
Are sucked one by one from the set position and moved to the fitting position, and the glass plates G on which the beads B have been fitted are stacked at the stock position.

Specifically, the movable table 12 is rotatably attached to the base 11 about a vertical axis, and is rotated in a vertical plane about the horizontal axis at the upper end of a pillar member 13 erected on the movable table 12. A movable arm 14 is attached, and an arm 15 that rotates in a vertical plane about a horizontal axis is attached to the upper end of the arm 14, and the tip of the arm 15 is attached around the axis of the arm 15.
The arm 16 that rotates by 0 ° is attached, and this arm 16
An actuator 17 is rotatably attached to the tip of the actuator, a cross-shaped plate 18 is attached to a bracket at the tip of the shaft of the actuator 17, and a suction cup 19 connected to a vacuuming device is provided at the tip of the plate 18.
8 is provided with a clamp claw 20 which can be opened and closed by a cylinder or the like.

The bead supply device 30 rotatably supports a drum 32 around which a bead B is wound on a side surface of a pedestal 31, and a bead drive mechanism 33 is provided on an upper surface of the pedestal 31, and a drive mechanism 33 is driven by a motor 34. By rotating the drive roller 35, the bead B inserted between the drive roller 35 and the pressing roller 36 at a predetermined pressure is pulled out from the drum 32 and is sent toward the fitting position. A tension roller 37 is arranged between the drive mechanism 33 and the motor 34.

A cutter 38 is provided downstream of the drive mechanism 33.
And a wedge member 39 for spreading the bead B is provided downstream of the cutter 38. The guide roller 4 is provided at the end of the wedge member 39.
0 is provided, and a pusher 41 for pressing the bead B against the end of the glass plate G is provided below the guide roller 40, and the start end and the end of the bead B fitted to the glass plate G are smoothly provided below the pusher 41. A leveling roller 42 is arranged so as to be continuous with the above.

In order to fit the beads B to the peripheral edge of the glass plate G by using the above-described fitting robot 10 and bead supply device 30, for example, when the glass plates G are stacked in a horizontal state and are stacked, By rotating the movable table, the arms, and the like that form the robot 10 by a predetermined angle, the suction cup 19 is brought into a downward horizontal state, and in this state, the upper surface of the glass plate G is sucked. When the glass plate G is adsorbed, the movable table, the arm, etc. are rotated by a predetermined angle in the same manner as described above, so that the glass plate G is brought into a vertical state to face the fitting position. This state is shown in FIG.

Next, as shown in FIG. 2, the glass plate G is pushed out toward the bead supply device 30, the tip of the bead B is fitted to a part of the peripheral edge of the glass plate G by the pusher 41, and the tip of the bead B is clamped. Close the claw 20 to prevent it from coming off.

After that, the bead B is delivered by the drive mechanism 33 and the glass plate G is delivered at a speed equal to the delivery speed.
Straight down. And bead B is glass plate G
When it has been fitted to the corner part of, the glass plate G is rotated 90 ° and lowered straight downward again.

On the other hand, when the bead B is fed out by the drive mechanism 33, the bead B is left at the position corresponding to the corner portion of the glass plate G so that only the edge portion of the bead B remains.
Cut at 8. In order to cut the bead B so that only the edge portion remains with the cutter 38, the cutter 38 is set to a low position with the cylinder unit 38a. By cutting in this way, when the bead B is fitted on the entire circumference of the glass plate G, the bead B does not swell at the corner portion of the glass plate, and the corner portion of the glass plate is exposed.

The bead B is cut by the cutter 38 at the time when the bead B is extended longer than the entire circumference of the glass plate G by the amount that is expected to shrink over time. At this time, the cutter 38 is set to a high position by the cylinder unit 38a.

As described above, when the length of the bead B fitted on the entire circumference of the glass plate G is extended by an amount corresponding to the contraction, the bead B first fitted on the glass plate G as shown in FIG. Start B1 and end B2 fitted last
And are different. In order to correct this step difference, the projecting piece 43 attached to the bead supply device 30 or the like is used.
Here, as shown in FIGS. 3 (a) and 3 (b), the projecting piece 43 has a pressing portion 43a whose upper end extends in a fork shape toward the glass plate, and a side surface thereof serves as a guide portion 43b.

Then, in order to process the seam of the bead using the projecting piece 43, the end B2 of the bead is set to the position shown in FIG.
The glass plate G is lifted in the direction of arrow A (slightly upper right direction in the drawing) while being in contact with the lower surface of the pressing portion 43a as shown in FIG. Then, the end B2 of the bead is pressed against the guide portion 43b and is fitted into the glass plate G as shown in FIG.

However, in this state, a gap t remains between the start end B1 and the end B2 of the bead B. Therefore, as shown in FIG. 5, the start end B1 and the end B2 of the bead B are pressed against the leveling roller 42, and in this state, the glass plate G is reciprocated several times in the vertical direction to be handled by the leveling roller 42. Then, the starting end B1 and the ending end B2 are made flush and continuous.

When the bead B is fitted to the glass plate G, the bead B and the glass plate G are spot-bonded by a quick-acting adhesive 50 as shown in FIG. By doing so, the bead B and the glass plate G do not shift during stocking or transportation after they are fitted. It should be noted that, if the adhesive force lasts forever, the adhesive force hinders the elasticity of the bead B and invites the intrusion of water, so that the adhesive force is preferably low.

Further, in the above embodiment, the abutting portion between the starting end B1 and the terminating end B2 of the bead B is located at the center of the side edge of the glass plate G, but as shown in FIG. May be cut into a ring shape, leaving the edge portion, and this portion may be locked to the corner portion of the glass plate G as shown in FIG. By doing so, the clamp claw 20 becomes unnecessary.

[0022]

As described above, according to the present invention,
The length of the bead supplied from the bead feeder is set to be longer than the entire circumference of the glass plate by the amount of contraction of the bead over time, so that the bead seam can be maintained for a long time after the building is completed. Rainwater will not enter.

Further, when the bead is fitted, the bead and the glass plate are spot-bonded with an immediate-acting adhesive so that the bead is kept in stock and the bead does not shift during transportation. By making the adhesive less durable, it becomes better compatible with the sash after being attached to the sash.
