Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting a resin-coated molded product, and more particularly to a technique for satisfactorily and quickly cutting a coated resin sheet.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, resin sheets 2 and 2 are provided on the front and back surfaces of a core material 1 with appropriate intervals and the resin sheets on the front and back surfaces between the core materials 1 and 1 are covered. In a cutting device for a resin-coated molded product, which cuts the resin sheet 2, 2 between the core materials 1, 1 with respect to the work a to which the work pieces 2, 2 are bonded, is provided on the base body 3 running on the work a. The cutting blade 4 is moved up and down to cut the resin sheets 2 and 2 between the core materials 1 and 1.

[0003]

However, in the case of such a structure, when the resin sheet 2, 2 is cut by the cutting blade 4 before being sufficiently cooled, the uncured resin sheet 2, 2 cannot be cut unless a sufficiently large stroke is taken, and the resin sheets 2 and 2 adhere to the cutting blade 4 side, resulting in defective cutting. If it waits until it is sufficiently cooled, it takes an unnecessary time, and when the cutting blade 4 cuts after the passage of time, the temperature on the cutting blade 4 side rises, which is also good. There was a problem that it was difficult to cut easily.

[0004] The present invention is intended to solve such problems, and an object may not wait for sufficient cooling of the resin sheet, to suppress the temperature rise of the or disconnect blade Moreover, the moving speed of the work and the substrate are more than necessary.

[0006]

A cooling device 5 that discharges cool air is attached near the cutting blade 4, and the cool air discharged from the cooling device 5 is sprayed onto the resin sheets 2 and 2 at the cutting point to rapidly cool the spraying point. The cutting blade 4 descends after cooling for a certain time without waiting for the cooling of the entire resin sheets 2 and 2.
Early in <br/> Dropping resin sheet 2 and 2 parts of the cooled locations come. Therefore prevents the resin sheet 2 and 2 rather name may adhere to the cutting blade 4, also it is disconnected blades 4 to increase the temperature. In addition, in the cutting area for the workpiece a being transported
When it reaches, the base body 3 travels, and the moving speed of the work a and the basic
The cooling device 5 operates in a state in which the traveling speed of the body 3 is synchronized.
To cool the resin sheets 2 and 2 for a certain period of time.
After that, the cutting blade 4 descends and the resin sheets 2 and 2 between the core materials
Cut the part. Therefore, the moving speed of the work a and the substrate
Make the travel speed stroke of 3 larger than necessary.
Quick and reliable cutting with narrow stroke

EXAMPLE A substantially gate-shaped traveling wheel on the base body 3 side for traveling is mounted on a rail 7 on the fixed base 6 side so as to be rotatable, and the base body 3 is mounted on the fixed base 6 at an appropriate traveling drive section. It is configured to run freely. An elevating table 8 is erected on the base 3 side so as to be movable up and down with respect to the guides 9, 9 and a cutting blade 4 is attached to the elevating table 8. Is moved up and down with respect to the work receiving portion 10 so that the work a can be cut.

The work a is covered with resin sheets 2 and 2 such as vinyl chloride sheets on the front and back of a core material 1 which is sent out by a conveyor at appropriate intervals and which is formed into a plate shape with wood, aluminum, iron or the like. In addition, the resin sheets 2 and 2 on the front and back sides are heat-bonded between the core materials 1 and 1.
In order to coat the resin sheets 2 and 2 on the front and back of the core material 1 in this way, for example, the resin sheet 2 on the back surface is drawn out on the conveyor, and the core material 1 is drawn out on the conveyor at appropriate intervals.
After that, the resin sheet 2 on the surface is laminated, and then transferred to the heating step, and the core material 1, the resin sheet 2, and the resin sheets 2 and 2 are heat-bonded to each other. In such a case, an adhesive may be used.

[0009] In element run line to the substrate 3 side, the cooling device 5 is attached for ejecting cool air to the vicinity of the cutting blade 4. But conveyance to reach its cutting zone relative to which the workpiece a <br/> Ru and group member 3 is traveling, and a metal detector, etc. reflective phototube device, between the core 1, 1 gaps and are detected recess 2a is detected disconnected position of the resin sheet 2 and 2 between the core 1, 1, element running speed of the moving speed and the substrate 3 of the word over click a
In a state where and are in synchronism, the cooling device 5 operates to cool the recessed portion 2a of the resin sheets 2 and 2. After cooling for a certain period of time, the lift 8 is lowered and attached to the lift 8.
The cutting blade 4 cuts the resin sheets 2, 2 between the core materials 1, 1. Thus follow directly word over click a and recesses 2a was cut to escort returns to its then base 3 the original position, and detects the recess 2a of the next resin sheet 2 and 2, this It is the one that follows and runs along with it to cool and cut. Add <br/> run cutting mechanism that written, can be variously design changes.

[0010] By cooling device 5 is attached for ejecting cool air to the vicinity of the thus disconnect blade 4, cool air discharged from the cooling device 5 is injected into the resin sheet 2 and 2 parts of the cutting point, The resin sheet 2 and 2 are designed to quench the injection point.
After cooling for a certain time without waiting for the entire cooling , the cutting blade
4 By cuts early resin sheet 2 and 2 parts of points that have been cooled been lowered, to adhere the resin sheet 2 and 2 the cutting blade 4 Turkey Togana rather, also disconnect blade 4 GaNoboru that temperature
Suppress. For the work a being transported,
When the cutting area is reached, the substrate 3 runs and the work a moves.
With the speed and the traveling speed of the base body 3 synchronized, the cooling device 5
Activates to cool the resin sheets 2 and 2 for a certain period of time.
After cooling, the cutting blade 4 descends and the resin seal between the core materials
Cut the 2 and 2 parts. Therefore, the moving speed of work a
And the travel speed of the base body 3 is set larger than necessary.
With a small stroke without scratching, resin coating
Quickly and surely cuts shaped products.

[0011]

As described above, according to the present invention, since the cooling device for discharging the cool air is provided in the vicinity of the cutting blade, the cool air discharged from the cooling device is sprayed on the resin sheet portion at the cutting point. The resin sheet portion at the cooled portion is cut while cooling the entire portion of the resin sheet at an early stage without waiting for the entire resin sheet to cool, so that the resin sheet does not stick to the cutting blade. and disconnect blade can be suppressed to heating, versus the work being conveyed further
Then, when it reaches the cutting area, the substrate is run and the workpiece
Cooling device with the moving speed and the traveling speed of the substrate synchronized
Activates to cool the resin sheet and cool it for a certain period of time
After that, the cutting blade descends to remove the resin sheet part between the core materials.
Since it is cut, the moving speed of the work and the substrate
It is not necessary to increase the travel speed stroke more than necessary , and there is an advantage that a small stroke allows a quick and reliable cutting operation of the resin-coated molded product.
