Description

[0001]
[Industrial applications]
The present invention relates to a wrap film lamination how to wear method for attaching the wrap film in an automobile hood having a washer nozzle.
[0002]
[Prior art]
To prevent defects such as discoloration and scratches on the painted surface due to acid rain, bird droppings, iron powder, dust, etc. during transportation and storage of the completed car in the factory until it reaches the hands of the user, There is a method of attaching a protective wrap film to a painted surface.
[0003]
By the way, the bonnet of an automobile is provided with a washer nozzle that blows out a washer liquid for washing the windshield.If this washer nozzle is covered with a wrap film, the washer liquid remaining between the tank and the washer nozzle becomes hot. There is a problem that it is pushed out due to a change or the like and enters between the wrap film and the painted surface. For this reason, after attaching the wrap film to the bonnet, the portion of the wrap film covering the washer nozzle was cut off with a cutter knife, but at this time, an unskilled worker cut the painted surface of the bonnet with a cutter knife. There was a problem that would hurt.
[0004]
Therefore, a perforated adhesive film is pasted in advance around projections such as a washer nozzle protruding from the painted surface, and a wrap film is adhered thereon, and then the wrap film is cut from above the perforated adhesive film with a cutter knife. A method of excision is proposed in Japanese Patent Application Laid-Open No. Hei 5-237935.
[0005]
[Problems to be solved by the invention]
However, the above-mentioned conventional method requires a special perforated pressure-sensitive adhesive film, which not only increases the cost, but also has a possibility that the coated surface may still be damaged by a cutter knife.
[0006]
The present invention has been made in view of the above circumstances, and has as its object to surely prevent a painted surface from being damaged when a wrap film is adhered to a bonnet so as not to block a washer nozzle.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 is a wrap film sticking method for sticking a wrap film to a hood of an automobile having a washer nozzle, wherein the wrap is pulled out from a roll by a predetermined length. A step of temporarily adhering the rear end side of the film to the upper surface of a temporary adhering member extending in the width direction of the wrap film, and a step of forming an opening larger than the size of the washer nozzle in the temporarily adhered wrap film; A step of separating the wrap film from the roll along the temporary bonding member, and a step of bonding the separated wrap film to a bonnet such that the opening surrounds a washer nozzle .
[0008]
[Action]
According to the configuration of the first aspect, an opening larger than the size of the washer nozzle is formed in the wrap film in a state where the wrap film drawn from the roll is temporarily attached to the temporary attaching member. Subsequently, the wrap film is cut off from the roll along the temporary sticking member, and the cut wrap film is stuck to the bonnet such that the opening surrounds the washer nozzle .

A pair of cutting holes 40 ₁ , 40 ₁ are formed in the punching plate 40, and a pair of cutting blades 41, 41 provided on the lower surface of the elevating plate 38 are formed in the pair of cutting holes 40 ₁ , 40 ₁ from above. Opposite to fit.
[0021]
Next, the operation of the embodiment of the present invention having the above-described configuration will be described.
[0022]
When the vehicle V conveyed by the conveyor C stops at the wrap film sticking station, the operator pulls out the wrap film F from the roll R along the bars 30 and 30 and pulls the tip of the wrap film F to a predetermined position corresponding to the model of the vehicle V. positioning mark 30 _1, 30 _1; 30 _2, 30 _2; 30 _3, to match the 30 _3. When the wrap film F is lowered in this state, the rear end side of the wrap film F is temporarily attached to the upper surface of the temporary attaching member 11, and the leading end side of the wrap film F is temporarily attached to the upper surface of the punching plate 40.
[0023]
At this time, the carriage 12 of the wrap film cutting device 7 is retracted to the position shown in FIG. 2 so as not to hinder the drawing out of the wrap film F.
[0024]
Subsequently, when the cylinder 36 of the wrap film punching device 31 is driven to expand and contract to move the elevating plate 38 downward and upward one reciprocating stroke, the pair of cutting blades 41, 41 causes the pair of cutting holes 40 ₁ of the punching plates 40, 40. , 40 ₁ from above and a pair of openings F ₁ , F ₁ are formed in the wrap film F. Thus, since the cut holes 40 _1, 40 fitted to _one of the cutting edges 41, 41 of the wrapping film F in a state of temporarily adhered to the upper surface of the punching plate 40, 40, and wrapping film F is pulled The openings F ₁ , F ₁ with good appearance can be formed with high precision without extending or distorting.
[0025]
Next, when the operator grips the grip 18 of the wrap film cutting device 7 and moves the carriage 12 along the guide rail 8, one side edge of the wrap film F and the upper guide plate 29 provided on the carriage 12 And the wrap film F is cut by the cutters 23, 23.
[0026]
At this time, since the wrap film F is temporarily attached to the upper surface of the temporary attaching member 11 and is pressed by the guide plate 29 from above, the wrap film F remains in contact with the cutters 23 from below. It cannot escape upwards and is reliably cut. Moreover, when the first pulleys 24, 24 and the second pulley 26 that engage with the wire 27 rotate with the movement of the carriage 12, the cutters 23, 23 integrated with the first pulleys 24, 24 rotate. Can be cut sharply. The first pulleys 24 and 24 and the second pulley 26 that engage with the wire 27 also have a function of keeping the moving speed constant in order to give a predetermined resistance to the movement of the carriage 12.
[0027]
Then, when the wrap film F having a desired length is cut off from the roll R, two workers peel off the wrap film F from the temporary attaching member 11 and the punching plate 40 by holding the four corners of the wrap film F. F is moved onto the hood B of the automobile V. Then, the wrap film F is placed on the bonnet B such that the pair of openings F ₁ , F ₁ coincide with the pair of washer nozzles N, N, and is then adhered to the bonnet B with a rubber squeegee.
[0028]
As described above, by forming the openings F ₁ and F ₁ in the wrap film F in advance, even an unskilled worker can easily and reliably perform the attaching operation of the wrap film F. Thus, damage to the painted surface of the hood B can be avoided reliably.
[0029]
Although the embodiments of the present invention have been described in detail, various design changes can be made in the present invention without departing from the gist thereof.
[0030]
For example, in the invention of claim 1, the wrap film Ri can der to the opening F _1, F ₁ of F formed by any means, it is possible to decouple the or wrap film F from the roll R by any means It is .
[0031]
【The invention's effect】
As described above, according to the invention described in claim 1, the rear end side of the wrap film pulled out from the roll by a predetermined length is temporarily attached to the upper surface of the temporary attaching member extending in the width direction of the wrap film. The step of attaching, the step of forming an opening larger than the size of the washer nozzle in the temporarily attached wrap film, the step of separating the wrap film from the roll along the temporary attachment member, and the opening of the separated wrap film into the opening By attaching the wrap film to the bonnet so as to surround the washer nozzle, even an inexperienced worker can attach the wrap film without damaging the painted surface of the bonnet, Thereby, the wrap film can be stably held and the cutting operation can be easily and reliably performed .
