DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet which is suitable for use, for example, for sticking a sticking sheet such as a protective film which is flexible and has excellent followability to the surface of a large-sized work having an uneven surface. The present invention relates to an attaching device and a sheet attaching method.

[0002]

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

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

[0004] This is because the flexible sheet such as the protective film of the wheel itself is thin and has essentially no shape-retaining property. This is because it is extremely difficult to make the sheet conform to the uneven shape even when the sheet is to be stuck on the surface of a large workpiece.

[0005] For this reason, for example, Japanese Patent Publication No. Hei 2-4464 discloses a method of preparing a molding die having a molding surface in which the surface of a work (molded product) is affixed to the sheet attachment surface, and the molding surface of the molding die is copied. There has been proposed a sheet in which a sheet formed in such a shape is pressed against and adhered to a sheet attaching surface of a molded article to thereby automate the operation of attaching such a sheet.

[0006]

However, as in the above-mentioned prior art, the manual sticking operation of the operator requires a great deal of labor and the production efficiency is extremely low. The one described in the gazette uses a molding die having a molding surface in which the surface of the work is affixed to the sheet pasting surface, so that it is not only difficult to manufacture this molding die, but also to mold the molding die. In such a case, operations such as mold clamping and mold opening are required, and this becomes a bottleneck in a series of sheet attaching operations, and it is considered that productivity is deteriorated.

[0007] In view of the above, the present invention provides a method for automatically and more efficiently forming a sheet on the surface of a work, even if the work is large and has irregularities on the surface, without using a molding die conforming to the shape of the work. It is an object to provide a product that can be attached in a short time.

[0008]

In order to achieve the above object, a sheet sticking apparatus according to the present invention is arranged such that a sheet continuously supplied on a long backing sheet is sequentially conveyed on a conveyor. A labeling head having a peel plate for peeling off the advancing end of the sheet from the backing sheet by rapidly folding the backing sheet in the middle of the supply path of the backing sheet. , located in front of the work the peel plate freely travel along the conveying direction of, and forward while maintaining suction end portion of the sheet was peeled off from the backing sheet, a portion of the sheet
Pull forward and drop the end of the sheet onto the work below.
And the vacuum grid which performs the air blow to this is connected to the peel plate side end portion of the vacuum grid in synchronization with the conveyance of the sheet feeding and the workpiece in the forward end of the vacuum grid blown toward the air downward, the sheet And an air blower for affixing the sheet to the surface of the work while gradually peeling off the sheet from the mount .

Here, the labeler head and the vacuum grid may be connected to the lower end of a vertically movable lifting plate to form a vertically movable labeler unit. Further, the sheet sticking method is a sheet sticking method for sticking a continuously supplied sheet held on a long backing sheet to a surface of a work sequentially conveyed on a conveyor, wherein the backing sheet is abruptly attached. the forward end of the sheet is peeled from該台paper by folding, the withdrawn part of the seat forward while sucking and holding the end portion of the release sheets, the ends of the sheet on a lower side of the workpiece Hanging, and then, while blowing out the sheet in synchronization with the work transfer direction, perform air blow to blow air toward the sheet from above the sheet, and gradually peel the sheet from the backing paper.
The method is characterized in that the sheet is attached to the surface of the work while the sheet is attached.

[0010]

According to the present invention constructed as described above, by rapidly folding back the running mount, the end of the sheet successively supplied while being held by the mount is peeled off from the mount by utilizing its rigidity. Then, the sheet is pulled out while holding the end of the peeled sheet by suction, and the suction and holding is released to hang down so as to cover the work surface. Then, while transporting the work, the sheet is sequentially fed out while being gradually separated from the mount in synchronization with the work, and air is blown from above onto the sheet to blow the sheet onto the surface of the work by air blowing. The sheet is pressed tightly by the wind pressure, whereby the sheet can be automatically attached to the surface of the workpiece without using a molding die, while conforming to the shape of the surface.
