Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is an optimal sheet to be used for sticking a sticking sheet such as a protective film which is flexible and excellent in conformability to the surface of a large work having unevenness on the surface. The present invention relates to a pasting device and a sheet pasting method.

[0002]

2. Description of the Related Art For example, in the case of an aluminum wheel of an automobile, after the production of the automobile, the surface of the wheel is flexibly followed in order to prevent the surface of the wheel from being scratched or soiled during storage or transportation. It is widely practiced to attach a protective film having excellent properties and peel off the protective film at the time of sale.

Conventionally, the work of sticking a sheet onto a work surface having a large and uneven surface (not a flat surface), such as the work of sticking a protective film of this kind to an automobile wheel, is
Generally, it is performed manually by a worker.

This is because the highly flexible sheet such as the wheel protective film itself has a thin wall and has essentially no shape-retaining property. This is because it is extremely difficult to make the sheet conform to the shape of the unevenness even if the sheet is attached to the surface of a large workpiece.

For this reason, for example, as Japanese Examined Patent Publication No. 2-4464, a molding die having a molding surface in which the unevenness is opposite to the sheet pasting surface of the work (molded article) is prepared, and the molding surface of this molding die is followed. It has been proposed to automate the sticking work of this kind of sheet by pressing and sticking a sheet formed into a different shape to the sheet sticking surface of the molded product.

[0006]

However, as in the above-mentioned conventional example, in the sheet sticking work by the operator's manual work, a great deal of labor is required and the production efficiency is remarkably low. On the other hand, Japanese Patent Publication No. 2-4464. In the one described in the publication, it is necessary to separately prepare a molding die having a molding surface in which the unevenness of the sheet is affixed to the sheet pasting surface of the workpiece and use it according to the work. It is considered troublesome.

In view of the above, the present invention automatically attaches a sheet to a surface of a large work without using a mold suitable for the shape of the work even if the work is large and has irregularities on the surface. The purpose is to provide the things that can be done.

[0008]

In order to achieve the above object, in the sheet sticking apparatus according to the present invention, sheets that are continuously supplied while being held on a long mount are sequentially conveyed on a conveyor. A sheet pasting device for pasting onto the surface of the incoming work, positioning the work carried in from the previous process and lowering the detection plate to select at least the height of the work, and further the size of the work and the type of work. And a sorting unit that is located on the downstream side of this sorting unit, and lowers the mount directly above the work to attach the sheet to the surface of the work while gradually peeling the sheet from the mount in synchronization with the conveyance of the work. A sheet pasting section and a pressing section for lowering the pressing member to a position where it abuts the surface of the work, pressing the sheet toward the work over almost the entire area and sending the sheet to the next step. It is characterized in.

The sheet sticking method is a sheet sticking method for sticking a sheet, which is held on a long mount and continuously supplied, onto the surface of a work successively conveyed on a conveyor. The height of the work is selected, the mount is lowered to a position just above the work according to the height of the work, and the mount is rapidly folded back to peel off the forward end of the sheet, in synchronization with the conveyance of the work. It is possible to stick the sheet on the surface of the work while gradually peeling the sheet by sending out the mount, and then lower the press member according to the height of the work to press the sheet over the almost entire area of the work. It is a feature.

[0010]

According to the present invention configured as described above, at least the height of the work is selected after the work sequentially carried in from the previous process is positioned at a predetermined position, and this height is selected. The sheet is automatically attached to the surface of the work while gradually peeling the sheet from the mount at a position suitable for the work, and the sheet attached to this work is pressed against the work by the press member to prevent the sheet from peeling or rising. In this state, it can be sequentially carried out to the next step.
