DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bead for a sash door glass plate (also referred to as a "glazing channel").
In particular, the present invention relates to a bead fitting method and a device capable of efficiently fitting a bead made of an elastic material to the periphery of a glass plate without expansion and contraction.

[0002]

2. Description of the Related Art A sash door is generally constructed by interposing a bead between the frame of the sash door and a glass plate, which acts as a buffer and watertight. This bead is made of a soft synthetic resin material having a substantially U-shaped cross section, and when the sash door is assembled, it is fitted to the periphery of the glass plate before supplying the glass plate to the assembly line.

FIG. 13 is a side view of a conventional bead fitting device.

In the bead fitting step, the glass plate G
Glass plate handling mechanism 51 (Japanese Patent Laid-Open Publication No. Hei 5-261629) for moving downward while holding the side edge of the glass plate in the vertical position, and sending out the bead B facing the side edge of the glass sheet held by the glass sheet handling mechanism. By cooperating with the bead supply mechanism 52 (Japanese Patent Application Laid-Open No. 5-261825), the beads are fitted so that the side edges of the glass plate are accommodated in the grooves of the beads to be fed.

The bead supply mechanism 52 includes a bobbin 54 in which the bead B is wound in a coil shape and a feed roller 55 for feeding out the bead B from the bobbin 54, and the side of the glass plate G facing the bead outlet 56. Bead B on the edge
And the beads are continuously fitted.

A bead cutting means 57 is provided on the front side of the bead outlet 56 to cut the bead each time the bead of each glass plate has been fitted. In addition, the bead is attached to the glass side edge at the corner of the glass plate. Make a cut at the bottom of the bead on the outside corner of the bead to bend along.

The cutting procedure is as follows. When the corner of the glass plate G or the starting end of the bead reaches a predetermined position, the supply of the bead is stopped and the bead is cut off, the bead is cut, and the side adjacent to the corner is raised. Then, the fitting is continued by feeding the glass and feeding the beads again.

Next, when the corner of the glass plate reaches the bead outlet 56, the adjacent side sandwiching the corner is raised to a position facing the bead outlet, and a bead is fitted on a new side edge. The operation is repeated for each side.

At the start and end portions of the bead, the end portion is cut into a long length and pushed in, so that there is no gap between the start and end due to the shrinkage of the bead with time, and the smoothing roller 58 handles and fits without any gap. (Japanese Unexamined Patent Application Publication No. 5-261
630).

However, the bead is repeatedly supplied and stopped in a glass plate unit in accordance with the corner processing of each side. At this time, the bead is a soft elastic member having elasticity. In particular, at the time of start-up, the feeding amount is not constant due to its elongation and loosening, the fitting is not uniform, and the bead may be broken or protruded, so that problems in assembly quality and work for repair and adjustment are avoided. Because of the lack thereof, it was a bottleneck in the bead fitting process.

For example, when a predetermined bead length is not ensured at a corner of a glass plate, the bead is extended from both sides of the corner to largely expose the corner of the glass plate, or a small cross section of the bead is broken. Problems arise.

In addition, when performing bead cutting, it is necessary to stop the bead supply and perform accurate alignment. Therefore, it takes time to stop and restart the bead feeding at the four corners, and the bead fitting process is required. If the accuracy of cutting at the end of the bead is low, it is not possible to secure a predetermined margin length with the beginning of the bead.If it is too long, re-cutting is required, and if it is too short, the bead shrinks. There are gaps and workability and quality problems are inevitable.

Further, after the bead is fitted, in order to fit the bead forming the soft elastic member to the glass side edge forming the hard member, a manual operation of lightly pressing the fitted bead from above is required. In short, this operation complicates the fitting process, and as a result, the production line is disturbed due to stagnation or the like.

A first object of the present invention is to improve the assembling quality relating to bead fitting by feeding out a bead made of an elastic material at a constant speed in response to a bead feed command.
The purpose of is to make the bead supply amount adjustable,
The third purpose is to reduce the processing time of the corners of the four corners of the glass plate, and the fourth purpose is to hold down the beads after fitting the beads. The fifth object is to cut the end position accurately with respect to the start end of the bead to adjust the shrinkage of the bead with time, thereby securing the quality of the bead fitting process and speeding up the processing. It is in.
