DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gasket winding device for winding a gasket having a substantially U-shaped cross section around a face material such as a single-pane glass, a double-glazed glass, and a resin panel.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 9-60434 discloses a U-shaped section.
A method of winding a character-like gasket around a multi-layer glass has been proposed. In this winding method, a gasket having a substantially U-shaped cross section and a predetermined length is pressed into each side of the double-glazed glass. Specifically, four gaskets having the same length as each side of the double-glazed glass are pressed into each side and wound. In addition, one gasket having the same length as the total length of each side portion of the double-glazed glass and having three folds is sequentially pushed into each side portion while being bent at the folds and wound. .

[0003]

When the gasket is wound around the double glazing as described above, the gasket is transported from a gasket manufacturing place to a gasket winding place by a cart or the like. For example, a gasket extruded by an extruder is cut into a predetermined length, and is subjected to crease processing or the like to form a gasket of a used shape. I am carrying it. Then, the gaskets are taken out of the cart one by one, pressed into the sides of the double glazing, and wound. The transportation of the gasket by the above-described trolley is time-consuming, and has been one of the key points in reducing the efficiency of the gasket winding operation.

In order to solve the above-mentioned problem, the present inventors have automatically carried a gasket from a gasket manufacturing place to a gasket winding place by a transfer device.
However, when the gasket was transported with the opening facing upward so that the gasket could be easily pushed into the side of the double-glazed glass, it was unstable and easily collapsed. In order to transport the gasket stably, it is sufficient to transport the gasket with the opening facing downward.However, in this case, the transported gasket is pushed into the side of the multilayer glass after the opening is oriented upward and the gasket is pressed. Winding efficiency is poor.

Accordingly, an object of the present invention is to provide a gasket wrapping device which can solve the above-mentioned problems.

The first vertical member 140 is moved toward the surface material, and the gasket is pushed into one vertical side of the surface material by the horizontal gasket pressing roller 142, and the moving body 141 is moved upward along the first vertical member 140. It moves and pushes a gasket into one vertical side part of a face material sequentially, and mounts it. Thereafter, the first vertical member 140 is moved along the upper horizontal guide 139a, and the downward gasket pressing roller 143 is moved along the upper side of the face material, and the gasket is sequentially pushed into the upper side of the face material and mounted. .

Thus, the gasket can be automatically and quickly wound around the face material.

The manner in which the gasket is wound around the face material is not limited to the above, and one gasket pressing roller may be mechanically moved along the circumference of the face material, or may be applied to each side. Each of the four gasket pressing rollers may be mechanically moved along. Further, instead of the gasket pressing roller, a non-rotating pressing piece may be mechanically moved along the side of the face material to wind the gasket around four circumferences of the face material. Further, instead of mechanically moving the gasket pressing roller and the pressing piece, an operator may manually move the gasket pressing roller and the pressing piece. That is, the gasket wrapping machine 14 only needs to hold the face material in a substantially vertical orientation.

[0066]

According to the first aspect of the present invention, the gasket 20 processed into the shape to be used is transported with the opening facing downward, and the gasket is placed with the opening facing upward. Can be transported downward. Therefore, the gasket of the used shape can be transported in a stable state, and can be mounted by being pushed into the side of the surface material while being transported below the surface material, thereby improving the efficiency of winding the gasket.

According to the second aspect of the invention, the gasket can be turned upside down while being transported. Therefore, the gasket transfer efficiency does not decrease.

According to the third aspect of the present invention, since two gaskets can be conveyed to the two gasket winding machines 14, the two gaskets are used when two gaskets are simultaneously extruded by an extruder. It can be processed into a gasket having a shape and transported to two gasket winding machines 14. Therefore, the gasket can be quickly and efficiently wound around the two face materials.

According to the fourth aspect of the present invention, the face material is transported to the vicinity of the two gasket wrapping machines 14 in a substantially horizontal orientation, and the face material is placed on the two gasket wrapping machines 14 in a substantially vertical orientation. Can be transported as Therefore, in a state where a plurality of face materials are superimposed in a substantially horizontal orientation, they are transported and placed near the gasket wrapping machine 14 by a trolley or the like, and the placed face materials are set in a substantially vertical orientation and the gasket winding is performed. Can be transported to the wrapping machine 14, so that the face material can be transported to the gasket wrapping machine 1
4 can be safely transported.
