Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work table that can be used when performing various kinds of work, and more particularly to a sash assembly work table used to mount a sash on a glass panel material.

INDUSTRIAL APPLICABILITY The present invention can be used as a sash mounting device having a mounting portion capable of easily mounting the sash on the periphery of the glass and adapting to various sizes of glass.

[0003]

2. Description of the Related Art A rectangular panel material made of a glass plate or other plastic plate material constituting a window or wall surface of a building is
A bead made of an elastic material such as rubber is attached to the peripheral edge for maintaining hermeticity, mechanical protection, and packing, and a sash made of an aluminum molded body or a plastic material is fitted over the bead and attached.

Conventionally, for example, when a window glass panel material is assembled by mounting a sash on a glass plate, the glass plate is erected on a suitable supporting stand or wall, and beads are fitted on the upper and side edges, so that an operator After flipping the glass plate upside down and leaning it up again and fitting the bead into the remaining side, the worker similarly leans the glass plate upside down and fits the sash on the four sides of the glass plate while assembling the sash. I was doing.

On the other hand, there has been proposed a sash assembling apparatus in which a sash is easily attached to the peripheral edge of glass to improve work efficiency (Japanese Utility Model Publication No. 1-148240). The sash assembly device disclosed in this publication is "movable up and down with respect to the main body,
In addition, a glass placing portion that is rotatably provided in a horizontal plane and on which a glass can be placed freely, and a sash that is mounted around the glass placing portion and is vertically movable and is attached to the peripheral edge of the glass. In the sash mounting device, the sash mounting portion can be freely placed, and the carrying-in means for loading the glass into the glass mounting portion in a state in which the sash mounting portion is moved downward. " is there.

[0006]

However, in the above-mentioned method of fitting the sash while leaning the glass plate upside down and turning it upside down, the sash assembly work is inefficient and requires a great deal of time and labor. .

Further, in the sash assembly device disclosed in the above-mentioned publication, when the glass size is wide, the amount of overhang (protrusion length) from the mounting part changes, and when working with large size glass. The bending of the glass becomes large and it interferes with the assembly of the sash.Since the free movement is only rotation and vertical movement, the work position of the worker changes during the work on the long side and the short side, and the movement in the rotation direction is flexible. On the other hand, since there is no braking function, there is a drawback that the mounting portion rotates when the sash frame is mounted, and the glass slides on the mounting portion during the bead mounting work. That is, in the conventional sash assembly apparatus, the worker cannot perform the assembly work at a fixed position and must move the position during the work, which is not satisfactory in terms of workability.
In addition, when the glass size becomes large, the work becomes troublesome due to the bending of the glass, and the glass placed on the mounting table moves when the sash is fitted and the mounting table rotates and the table rotates smoothly. There is a problem that the work cannot be performed, or the worker has to work while pressing the glass and the mounting table by hand in order to prevent this, and an easy, quick and smooth work cannot be achieved.

The present invention has been made in view of the above-mentioned drawbacks of the prior art. The size and arrangement direction of the glass panel material,
An object of the present invention is to provide a sash assembly work table that allows a worker to easily and smoothly perform a sash mounting work at a fixed position regardless of the position of a work portion.
