DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet glass film sticking apparatus for sticking a resin film on the front surface of glass.

[0002]

2. Description of the Related Art In interior and exterior facilities of buildings, sheet glass is frequently used for windows and partitions. Sheet glass is an excellent material as a daylighting means with a blocking effect, but has the disadvantage that it is easily broken.If the building is distorted or damaged by an earthquake, the shattered fragments are scattered and dangerous, and the workability of cleaning up Can also be aggravated. Therefore, conventionally, an attempt has been made to attach a resin film to a glass surface to prevent scattering of fragments. As illustrated in FIG. 6, the film sticking operation is performed by placing the plate glass G on a horizontal table 17, laying an adhesive film on the surface of the cleaned glass via water, The surface of the film 16b is carefully rubbed from the end with a sponge 18 or the like, and the air between the glass and the film is pushed out and brought into close contact with each other. At present, all of these processes are performed manually.

[0003]

The glass used for building windows and partitions is large and thick, so it takes a lot of physical strength to carry it. Plate glass is usually stored in a leaning state. Since the sticking operation is performed on a horizontal table, it involves a transporting operation that changes the posture during the movement, and at least when it is lifted horizontally, it takes two people. Also, of course, everything is manual,
Not only is it inefficient and takes a long time, but also the work result depends on the skill level, which often results in defective products. Furthermore, when pasting by hand, it has to be carried out through water, so after the work is completed, a curing period of several days is required until it is completely pasted. In most cases, it is difficult to manage during that time. If the curing is not sufficient, for example, when a suction jig for transportation is used, a peeling phenomenon of the film occurs at the sucked portion, and the film must be re-attached. There have been many requests for automation of film sticking work, but this has not been realized due to installation space problems. In order to do this, it is necessary to remove the support shaft each time, so that the workability is poor, and the plate glass to be affixed varies depending on the construction location, so an adjustment mechanism to adapt to the thickness is required, etc. There were many tasks to be done.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a sheet glass film sticking apparatus (hereinafter simply referred to as a film sticking apparatus) which has been successfully automated for the purpose of improving installation space and workability. A heating roller that sandwiches the sheet glass supported in the inclined state from both the front and back sides and feeds the sheet glass in one direction in the middle of a transport path that supports the sheet glass movably in the lateral direction while being inclined, and between the heating roller and the sheet glass. Adhesive film supply means for feeding the adhesive film to the, the adhesive film supply means is inserted into the center of a film roll formed by winding a long mother film is attached a release film, and continuously the mother film Cut the film roll support shaft that can be pulled out and the drawn mother film to a width suitable for the width of the glass sheet Comprising a sectional blade, and unwanted film take-up shaft for winding the unnecessary components of the cut master film, a release film take-up shaft for taking up separating the release film from the mother films unnecessary components are removed,

Further, the film sticking mechanism 5 of the embodiment is provided in the middle of a film drawing path in order to cut the adhesive film into a width suitable for the width of the sheet glass, and moves in a direction perpendicular to the film feeding direction. An adjustable cutting blade 10 and an unnecessary film take-up shaft 11 for winding an unnecessary portion of the film cut by the cutting blade 10 are provided. Further, a release film winding shaft 12 for winding the release film separated from the mother film is provided to enable the use of a mother film on which a release film is bonded as an adhesive film.

One of the heating rollers 7 and 7a is of a fixed type (the heating roller 7a is located at the back of the drawing and is in contact with the pressing surface of the sheet glass), and the other (the heating roller is in contact with the adhesive film contacting surface on the near side of the drawing). Rollers 7) rotatably support a lower portion thereof on a bottom plate 6a (an upper end portion is a top plate 6b). A bearing 13 is slidable relative to the machine base 6 in a direction orthogonal to the sheet glass conveying direction and appropriately. A rod 14a, which is fixedly attached at a position and moves forward and backward of an air cylinder 14 fixed to the machine base 6 side, is connected to the bearing 13 so as to come in contact with and separate from the plate glass surface supported on the transport path. A stopper 15 is fixed to the tip of a rod 14b which also protrudes rearward from the air cylinder 14 and moves forward and backward integrally with the rod 14a. Different plates 15a of the plate thickness to 4b

In order to adhere the adhesive film to the glass sheet by the attaching device formed as described above, as shown in FIG. 2, a length in which the adhesive film is attached to the release film is attached to the film roll support shaft 8. A film roll R formed by winding a length of the mother film 16 is mounted, fed out through the guide shaft 9, and the adhesive film 16b peeled off from the release film 16a is sent to the heating roller 7, while the release film 16a is wound around the release film. Spindle 12
Wrap around. If the width of the glass sheet to which the film is to be attached is smaller than the width of the mother film 16, the cutting blade 10
Is fixed to a position corresponding to the width of the sheet glass, the film is fed so as to be cut into a predetermined width and supplied, and the cut unnecessary portion is wound around the unnecessary film take-up shaft 11. In this way, the adhesive film 16b having a width suitable for the sheet glass to be attached is supplied to the heating roller 7.

When the film setting is completed, the sheet glass G is set on the setting table 1 as shown in FIG. In this flat glass setting work, the flat glass stored in the leaning state is simply moved in an upright posture, and the lower edge is brought into contact with the rolling rollers 3, 3,. If the length is about 1m, it can be adequately handled by one person. Plate glass G with set
Is fed along the support surface into the film sticking mechanism 5, and the adhesive film 16 b supplied from the film roll is introduced so as to be sandwiched between the heating roller 7 and the plate glass G. Then, while controlling the temperature and the rotation speed of the heating rollers 7 and 7a, the plate glass G is sent out to the unloading table 2 while the adhesive film 16b is pressed against the surface of the plate glass G. Since the adhesive film 16b is pressed and heated by the heating roller 7, the adhesive film 16b is firmly fixed to the surface of the sheet glass G that has passed through the film sticking mechanism 16, and the sticking is completed. Therefore, since there is no need for drying, the attachment work can be performed immediately after the application is completed, and when the peripheral portion is cut, the cut end is sharp and the commercial value is high.
