BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a painted surface protection sheet, and more particularly to a painted surface protection sheet in a vehicle assembly and production line.

[0002]

2. Description of the Related Art Various types of interior materials are incorporated in a vehicle assembly and production line for a vehicle such as an automobile or a construction machine after the surface of the body is completely coated. During this assembling operation, the operator is likely to be scratched due to contact with the painted surface or contact with the interior material of the assembly. In addition, there is a problem that dirt or the like is adhered during this operation, so that a painted surface is covered until the completion of the assembling operation. For example, as a protection sheet for a painted surface of an automobile, a sheet formed by bonding a vinyl chloride sheet to a polyethylene foam material and forming the shape to approximately match the shape of the part to be protected which is a painted surface by vacuum molding or the like is used. Have been.

[0003]

In the conventional painted surface protection sheet, a hook material is attached to a side edge portion or the like and attached to a protected portion. However, the protected surface is protected by vacuum molding or the like. Because it is a molded product that has been shaped according to the shape of
If the shape of the protection part is slightly different, it cannot be used. For example, painted surface protection sheets formed on passenger car fenders are no longer available for fenders of a slightly different shape, and therefore, paint surface protection sheets must be formed for each vehicle type. Met.

Further, in this conventional example, the painted surface protection sheet is detachable at the side edge of the protected portion by the hook material, and it takes time for such attaching and detaching work, and this attachment is complete. If it is not located at a position, for example, if it is installed diagonally, the painted surface protection sheet is a molded product that conforms to the shape of the part to be protected, but the adhesion is poor, and dust or the like may enter the gaps. In some cases, the painted surface is damaged. Of course, a load is applied to the hook material, so that the hook material is easily damaged. If even one hook material is damaged, it is discarded. Further, since the conventional coated surface protection sheet is a molded product having a polyethylene foam as a core, a sense of discomfort is large when an operator comes into contact during assembly.

Accordingly, in order to solve the drawbacks of the conventional painted surface protection sheet, the present applicant superimposes the flexible polyurethane foam, the sheet and the fabric, and wraps and holds the magnet at least at its end. Painted sheet protection sheets have already been provided and are now widely used in vehicle assembly lines. In this invention, the use of a magnet is extremely unique, but further improvement is required in some assembly lines. This is because the magnet picks up fine iron powder and the like, and, in some cases, the painted surface may be damaged by the iron powder picked up by the magnet. On the other hand, the protection sheath
Some have pointed out that the surface should be improved to make it easier to remove.

Furthermore, in the assembly line of automobiles, the rate of automation is increasing in recent years, and the rate of robotization is increasing. However, the work of mounting the painted surface protection sheet is no exception, and it is necessary to provide a protection sheet that can be automatically mounted.

[0007]

The present invention has been further improved based on such a demand, and the gist thereof is as follows. That is, in the present invention, a soft polyurethane foam sheet sufficient to cover a painted surface and a synthetic resin film sheet or a synthetic resin laser having substantially the same shape are overlapped to form an integrated sheet. The hard core material along the upper edge is
The hook that is fixed to the upper edge of the top and the hook that hooks on the upper end of the painted surface and the gripper for automatic mounting protrudes from the core material,
On the other hand, a vehicle painted surface protection sheet wherein a long weight is fixed to the lower edge portion of the sheet, preferably, a fabric is integrally laminated on the surface of the polyurethane foam sheet. This is a vehicle protection sheet that can be automatically mounted.

The hook generally protrudes uniformly in the longitudinal direction of the core material, and the long weight is preferably a relatively soft rubber-like weight. The synthetic resin film sheet or the synthetic resin laser mentioned here may be an extremely general one, for example, a flexible film made of vinyl chloride resin, polyethylene or polypropylene is sufficient.

[0009]

According to the present invention, the front side is made of a synthetic resin film sheet or a synthetic resin laser, and the protected portion is made of a soft polyurethane foam sheet, or a fabric integrally laminated on this sheet. It has a soft surface that hits the painted surface and a synthetic resin laser or the like that does not easily scratch the surface and can easily wipe off dirt, and its effectiveness is high. Further, as a feature of the present invention, a core material is fixed to the upper end of the protection sheet along the upper end of the painted surface, so that a wide painted surface can be surely spread and covered, A gripping rib for automatic mounting is protruded from the core material, and the robot grips and moves the rib to lock the hook on the upper end of the painted surface. Spread along the painted surface, and It is possible to fix.

Further, in the present protective sheet, a long, preferably relatively flexible weight is attached to the lower end of the protective sheet so as not to be affected by wind or the like. For this reason, the protection sheet is not turned up by the force of the wind flowing in the factory, and can always be kept constant.

[0011]

The present invention will be described in further detail with reference to the drawings.
FIG. 1 is an example of a door panel 1 of an automobile, and 2 is a painted surface. Then, the protective sheet 10 of the present invention is attached to the painted surface 2 of the door panel 1.

FIG. 2 is a sectional perspective view of the protection sheet 10 taken along line AA. In such a protection sheet 10,
A vinyl chloride resin laser 12 is integrated with a 5 mm thick polyurethane foam sheet 11 by a frame laminating method.
Insects - Thin tricot fabric 13 on the surface of the bets 11 are stacked, a protective sheet - which forms a substrate 10 ₀ bets 10.

[0013] Then, the upper end of the body 10 _0, for example, extrusion molding and is being fixed polypropylene core 14 is long, the core 14 and the length of the frame of substantially the door panel is its length Have been. And, in this core 14,
Hook 1 to hook on top 3 of door panel 1
5 is formed. This hook 15 is preferably formed at the same time as the extrusion of the core 14, but may be a very short hook 15 in some cases. Is also good. The core 14 and the protective sheet - the preparative substrate 10 _0, the example of sewing 16, not limited thereto,
It may be fixed with an adhesive or a welder.

A rib 17 is formed on the core 14 so that it can be gripped by a robot device. It is preferable that the rib 17 be formed at the same time as the core 14 is extruded. A very short rib 17 may be used, and a rib 17 separate from the core body 14 may be used for automation.

[0015] The protection sheet - In the preparative substrate 10 _0, at its lower end Yes and confined the weight 18 with a rubber flexibility, in this example, the protective sheet - weight at DOO substrate 10 ₀ 18 After wrapping, sewing 19 was performed, but depending on the case, it may be integrated by an adhesive or welding. The core 14 does not necessarily have a length close to the width of the door panel 1. For example, two cores 14 may be formed to have a length close to the width of the door panel 1. It is also possible to fold.

[0016] In the Figure 3, the protective sheet - which shows an alternative example of a preparative substrate 10, being integrally fixed to the core body 14 is protected - and a synthetic resin Reza -12 bets substrate 10 ₀ A tricot ground 13, wherein the polyurethane sheet 11 is a core 14
This is an example that has not been reached. By doing so, the protective sheet - if bets 10 is mounted on the coated surface, the protection from the core body 14 of the lower sheet - a fact that can hang preparative substrate 10 ₀ is very close contact along the coated surface It was. In this example, the core body 14 and the hook 15 are extruded integrally, and at the same time, the rib 17 for automation is used.
Also shows an example of being integrally formed. The hook 15 is greatly curved, and covers the entire upper end 3 of the door panel 1 to mount the protective sheet 10 thereon.

[0017]

As described above, the protection sheet according to the present invention provides a protection sheet that can be easily mounted on a painted surface by a robot and can be easily removed.
Since the protective sheet itself does not have any habit on the painted surface, it can be used also for painted surfaces of various vehicles, not only to ensure the installation, but also to easily wash it off against dirt. Since it can be used repeatedly, it is possible to use it many times. As a result, the mounting workability is improved and its utility value is extremely high.
