Even if the stacking work can be done, the finish of the stacking is accurate and beautiful. Possible to provide a vacuum laminator is real.

The vacuum laminating apparatus according to the present invention will be described in detail below. FIG. 1 is a perspective view showing an embodiment of a vacuum laminating apparatus according to the present invention. FIG. 2 is a sectional view of the central portion of FIG.

In the vacuum laminating apparatus according to the present invention, as shown in FIG. 1, a heating / cooling house 3 formed by holding a heating mechanism 15 and a cooling mechanism 2 in a house frame 1 is moved up and down by an elevating mechanism 12 to move the diaphragm sheet 5 in place. The tensioned diaphragm base 4 also moves up and down by the lifting mechanism 12. The stage 6 is provided with a pipe 10 for exhausting by a vacuum pump 11, and a conveyor 7 is arranged. The transport plate 8 is adapted to move on the conveyor. The stacked body 9 and the stacked body are arranged on the transport plate.

The controller 14 lowers and raises the diaphragm base 4 by the elevating mechanism 12 and deactivates the vacuum pump 11 to stop the transport plate 8, the laminated base 9 and the diaphragm base 4 including the stacked body, the diaphragm sheet 5, and the stage. The air inside 6 is exhausted and air-supplied to form a decompressed atmosphere, and the elevating mechanism 12 lowers and raises the house frame 1. Further, the controller 14 deactivates the heating mechanism 15 at a timing, manages the temperature by the temperature sensor 13, manages the time by the timer, and deactivates the cooling mechanism 2 to manage the laminated state.

The vacuum laminating apparatus according to the present invention is shown in FIG.
The arrangement and shape shown in FIG. 2 are not necessarily required and may be appropriately selected depending on the shape and size of the stacked body.

The vacuum laminating apparatus according to the present invention comprises a heating / cooling house having a heating mechanism and a cooling mechanism held in a house frame, a diaphragm stand with a diaphragm sheet, and piping to a vacuum pump connected to a conveyor. And a controller for managing vertical movements of the heating / cooling house and the diaphragm base, temperature, time, and timing of the vacuum pump. The stage forms a vacuum closed system including the stacked bodies.

The house frame preferably has a shape that uniformly holds the heat energy of the heating mechanism and the cold air of the cooling mechanism and covers the glue in order to transfer the heat energy to the stacked body and the stacked body. Moreover, as the heating mechanism, a heater, an infrared lamp, a lamp, or the like is preferable. More preferably, it is an infrared lamp. As the cooling mechanism, a blower or the like is preferable.

A diaphragm sheet is stretched on the diaphragm base, and a temperature sensor is preferably arranged on the diaphragm sheet. A packing 16 is preferably arranged between the diaphragm base and the stage to prevent air leakage.

The conveyor provided on the stage is preferably a belt conveyor, a ball conveyor, a roller conveyor, or the like. More preferably, it is a roller conveyor. The transport plate placed on the conveyor is preferably movable not only inside the vacuum laminating apparatus of the present invention but also outside the vacuum laminating apparatus. If it can be moved to the outside of the vacuum laminating apparatus in this way, it is possible to easily attach / detach the laminated body and cover the laminated body.

The vacuum laminating apparatus according to the present invention as described above is
It is useful for forming laminates used for large signboards, large road signs, etc. A metal is preferable as the layered body. More preferably, it is aluminum or a lightweight alloy.
As the laminate, a plastic sheet coated with a heat-sensitive adhesive is preferable.

EXAMPLES Examples of the vacuum laminating apparatus will be shown below. The vacuum laminating apparatus according to the present invention is not limited to the embodiment.

As a heating mechanism on the inner surface of the house frame, 263
Individual infrared lamps are attached, a blower is attached as a cooling mechanism on the upper surface of the house frame to form a heating and cooling house, and the heating and cooling house is held by an elevating mechanism. Also,
A diaphragm sheet is stretched on the diaphragm base, a temperature sensor is arranged on the diaphragm seat, and the diaphragm base is held by an elevating mechanism.

Eighteen roller conveyors are arranged on the stage, packing is arranged around the stage in contact with the diaphragm base, and piping is connected from the bottom surface of the stage to a vacuum pump. In addition, a transport plate is placed on the roller conveyor and can be easily moved. The transfer plate has a layered body (approximately 2 m * 6 m
The aluminum road signboard) and the laminate (a vinyl chloride sheet coated with a heat-sensitive adhesive) were arranged. The diaphragm base, the diaphragm sheet, the packing and the stage are the roller conveyor, the transfer plate,
A vacuum state (negative pressure state) can be formed by including the laminated body and the laminated body, and the diaphragm sheet uniformly presses the laminated body against the laminated body by forming the vacuum state.

The transfer plate can be easily moved to another transfer stage having a roller conveyor, and the layered body and the stacked body can be set by this another transfer stage, which is very workable.

Further, the controller manages the vertical movement of the heating / cooling house and the diaphragm base, the temperature, the time, the ON / OFF timing of the vacuum pump, and the like.

The vacuum laminating apparatus having the above-mentioned structure has few manpower, can handle a large object to be laminated, and the completion of lamination is accurate, beautiful and reliable.
