In this case, the heater in the form of a blade has a structure in which a heating element such as a two-wire wire is arranged close to the back of the heater. The transparent film is heated by conduction or radiant heat from the plate.

In such a blade-shaped heater having a structure in which a heating element is arranged close to the back of the blade, the blade is heated by a heating element such as a niche opening wire. It takes time to heat up to the temperature. This time varies depending on the size of the blade, the required heating temperature, etc., but may be several minutes.] ?, and reduces the efficiency of the laminating device for convenience.

It is a partial side sectional view showing an example. BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side sectional view showing a first embodiment of a laminate device according to the present invention. In the above, reference numeral 11 is a cylindrical pressure roller having a predetermined width? It is disposed so as to be rotatable in the opposite direction from the top and bottom. The pressurizing roller 11 is driven by a motor (not shown) provided in the laminating device 10 by an appropriate gearing device. [Not shown) to the pressurized roller 11] 9. The pair of pressurizing rollers 11 presses the upper pressurizing roller by its own weight or a pressing spring (not shown) to the lower pressing roller. Yo ??

O PI The contact surface is kept under pressure. Pressurizing port

A heat-resistant synthetic rubber 12 such as a silicone resin is adhered to the surface of the resin to provide an appropriate elasticity. Behind the pressurizing roller 11 1, a pair of tensile rollers 14, also covered with a heat-resistant synthetic rubber 13 on the surface, presses the common tangent line α — la 11 The rotation speed of α and the tension roller 14, which is rotatably arranged at a position that coincides with the common tangent line of, is slightly faster than that of the pressure roller 11]. In the vicinity of the pressurized roller 11, there is a pressurized heat that heats the outer surface of the pressurized roller 11 along the longitudinal direction of the pressurized roller 11. A heat source such as an infrared lamp, a halogen lamp, or a tank lamp is used as the heating source. It has been done. Reference numeral 16 denotes a reflector for effectively directing the mature wire L from the heat-radiating lamp 15 to the pressure roller 11]), and a heat insulating material 24 is attached to the back surface. ing. Slightly below the common tangent of the heating roller 11 and the tension roller 14, the inlet table 17 and the outlet table 18, each having a surface parallel to this common tangent, are pressurized. Mouth

Are provided on the front side of the motor and on the rear side of the tension roller 14. Reference numeral 19 denotes a presser plate for radiating the laminated product sent on the outlet table 18 or correcting it when it is curled out. This presser plate 19 is made up of its own weight or spring! ), Which is held so that it can be pressed lightly against the exit table 18

O PI

? ⁰ A detector 25 for detecting the tip 21 a of the transparent film 21 is provided in the front direction of the pressure roller 11. As the detector 25, the switch may be turned on and off mechanically, or may not be connected to a micro tube, such as a micro tube. Switch ON for contact type-

It is conceivable that something is turned off. As shown in the figure, the light from the light emitting lamp 26 arranged above the table 17 is received by the light receiver 27 arranged below the table 17 In this way, when the tip 21a of the transparent film 21 is inserted and this optical path is cut off, a power supply switch (not shown) is inserted. That is what we did. The tip 21a of the film may be made opaque to facilitate this light path interruption.

In addition, a temperature detector 28 is disposed near or in contact with the pressure roller 11], and whether the surface of the heating roller 11 is maintained at a predetermined temperature. Is to be detected. For example, when the detection signal from the temperature detector 28 indicates a temperature lower than a predetermined temperature] ?, the current value flowing to the heat radiation lamp 15 is increased, When a high temperature is indicated, the surface of the pressure roller 11 is maintained at a predetermined temperature by decreasing the current value. Such a control can be easily performed by providing a temperature-sensitive resistance element whose resistance 変化 changes depending on the temperature.

Thus, the laser according to the present invention having such a configuration can be used. In the mounting device 10, the card nod 20 is sandwiched between the transparent films 21, and a laminate of the force 20 and the transparent film 21 is formed. Is inserted along the inlet table 17 in the direction of the pressure α — la 11, the tip 21 a of the transparent film 21 is detected by the detector 25]. Generates a detection signal, and the power supply switch is turned on. As a result, when the heat radiation lamp 15 is energized, the pressure roller 11 and the tension roller 14 are respectively driven to rotate in the same direction for a predetermined period of time. Is done. The reason why the drive timing of the pressure roller 11 and the tension roller 14 is delayed from the irradiation of the heat-radiating lamp 15 in this manner is additional. It takes time until the surface of the pressure roller 11 is heated and raised; However, in the laminating apparatus according to the present invention, since the heat-radiating lamp 15 is used as a heating source, it is not necessary to use a heating device such as a conventional one. The time required to raise the temperature to a predetermined temperature is shorter than that of heating with an element. This is because heat rays (infrared rays) L generated from the heat radiation lamp 15 are radiated directly to the outer surface of the pressurized roller 11, so that the heating impairment rate is good. These are the powers that come down. Also, halogen lamps have high infrared radiation transmittance and high heat radiation efficiency. If the infrared halogen lamp used for industrial heat sources and heating is used as the π-gen lamp, the temperature rise time can be shortened. And can be done. Therefore, in the laminating apparatus according to the present invention, the heat radiation lamp 15 passes through. y After the power is turned on, insert a laminate of cards 20 and transparent film 21 between pressurizing ports 11 with just a few seconds of timing. I can do it. The energization of the heat-radiating lamp 15 and the rotation of the pressurizing roller 11 and the tension roller 14 are performed by using a timer switch. You can take it.

The laminate of the cards 20 and the transparent film 21 inserted between the pressure rollers 11 is located on the outer surface of the pressure rollers 11]? Is done. This heating causes the transparent film to fuse to the surface of the card, and pressurizes it to form a complete contact, and completes the lamination of the card. In this case, since heating and pressurization proceed simultaneously, air does not enter the transparent film during the laminating action. The laminate product thus obtained is conveyed onto the outlet table 18 while being re-pressed by the tension roller 14 and being completely finished.

When the laminated product is completely transported onto the outlet table 18, the power supply to the laminated device 10 is stopped. It can be easily done using a switch. That is, the heat radiation lamp 15 is energized by the detection signal from the detector 25, and the pressure roller 11 and the tension roller 1 are supplied after the temperature rise. 4 is times耘蕙dynamic, not good by path to jar'll stop after being operated between continuing the time T _2. Also, during this time tau _2, when the next stack is inserted, operated subsequently is Re name of If so, it is possible to intermittently laminate many layers

If the diameter of the heating roller 11 'is increased, the heating and pressurizing state can be extended, and the finish 1) of the laminated product can be improved. You.
