The means (for example, a belt conveyor) 13 and a marker printed on the laminate sheet 1 are detected by a sensor and the feeder 12
A position control device (not shown) for controlling the delivery timing (that is, the overlapping position of the laminate sheet 1 and the sheet base material 2). The guide member is not limited to the guide roller 5 as long as it can guide the laminate sheet 1, and may have any configuration.

The adhesive coater 7 includes an adhesive tank 14 for storing a liquid adhesive, a coater roll 15 for attaching the adhesive attached to the outer peripheral surface to the surface of the laminate sheet 1, and an adhesive attached to the surface of the coater roll 15. It is composed of a roller 16 and the like for adjusting the amount of the agent and adjusting it uniformly.

The dryer 8 is for drying the adhesive on the surface of the laminated sheet 1 by applying warm air or hot air with a heater and a fan while the laminated sheet 1 is penetrated through a horizontally long drying cylinder. The dryer 8 may have any structure as long as it has a drying function, and may be, for example, an infrared dryer.

The pressure roller 9 sandwiches the laminated sheet 1 and the single-wafer base material 2 in a superposed state and securely press-bonds the laminated sheet 1 to the surface of the single-wafer base material 2 with an adhesive. Any configuration may be used as long as it is provided.

The laminate sheet 1 is a transparent sheet on which characters and patterns are printed in advance, and publicly known markers such as crosshairs are printed at predetermined positions. In addition,
The material of the laminate sheet 1 may be any material as long as it is printable and transparent, and may be colored.

Further, the position control device for detecting the marker of the laminate sheet 1 to control the superposition position of the single-wafer substrate 2, the conveyance speed of the laminate sheet 1, the distance from the feeder 12 to the superposition position, the conveyance speed of the conveying means, etc. The timing at which the single-wafer substrate 2 is sent out is controlled according to the condition (1).

Next, a laminating method carried out by the laminating apparatus having the above structure will be described. When the pre-printed laminated sheet coil 3 is set on the sheet coil stand 4 and the unwound laminated sheet 1 is hung on the guide roller 5 to operate, the coater roll of the adhesive coater 7 is provided immediately downstream of the sheet coil stand 4. 15 applies a liquid adhesive to one surface of the laminate sheet 1 (adhesive applying step).

The laminate sheet 1 which has undergone the adhesive application process is conveyed upward while being guided by the guide roller 5 and passes through the dryer 8. Then, the adhesive of the laminate sheet 1 is dried while passing through the dryer 8 (drying step).

The laminate sheet 1 which has passed through the dryer 8 descends while being guided by the guide roller 5, and is fed between the pressure rollers 9 in a state where the sheet base material 2 is superposed on the adhesive application surface. A detector of a position control device is arranged on the upstream side of the pressure roller 9, and this detector is used for the laminate sheet 1.
Marker is detected, and the feeder 12 aligns the single-wafer substrate 2 based on the signal from the detector and sends it out. Therefore, the single-wafer substrate 2 sent from the feeder 12
When the sheet is conveyed by the sheet-fed substrate conveying means 13 to be superposed on the laminated sheet 1, the sheet-fed substrate 2 is superposed on a predetermined position of the laminated sheet 1, and in this superposed state, the two sheets pass between the pressure rollers 9 and are pressed. The roller 9 is pressure-bonded by a pressure force and is bonded by an adhesive (bonding step).

Since the surface of the single-wafer substrate 2 to be polymerized on the adhesive-coated surface of the laminate sheet 1 has no unevenness due to the printing ink and no blocking powder is attached, the adhesion applied to the laminate sheet 1 Even if the amount of the agent is small, it is surely pressure-bonded and adhered, and even if the conveying speed of the laminate sheet 1 is made faster than the conventional processing speed, it is not affected by the powder or the like, so that the treatment is efficient. It can be performed.

The laminated sheet 1 that has passed between the pressure rollers 9 is conveyed to the cutting machine 10, and the laminated sheet 1 conveyed to the cutting machine 10 is cut into individual sheet substrates 2 by a cutter (cutting step). Even if the laminated sheet 1 is sent to the cutting machine 10 without stopping while the single-layer substrate 2 is closely attached to the lower surface, the cutter cuts the laminated sheet 1 diagonally according to the traveling speed of the laminated sheet 1. Therefore, it is possible to cut along the front and rear sides of the single-wafer substrate 2.

Then, the cut sheets, that is, the single-wafer substrates 2 having the laminated sheet 1 adhered to the surface and subjected to the glossy surface treatment, are sequentially conveyed one by one to the stacker 11 and stacked and stored in the stacker 11. It Therefore, if a certain number of sheets are stored, they can be collectively or manually taken out.

The sheet-shaped substrate 2 which has been surface-treated through the above steps has a sufficient gloss because it is laminated on the surface, but the surface of the sheet-shaped substrate 2 is not printed. However, since the predetermined items are printed on the transparent laminate sheet 1, after the treatment, it looks as if letters, patterns, etc. are printed on the surface of the sheet base material 2. It should be noted that rather than printing on the front surface of the laminated sheet 1,
When printing is performed on the opposite adhesive surface (the surface which is fitted to the single-wafer substrate 2), it looks as if it was printed on the surface of the single-wafer substrate 2 after laminating.

The laminating apparatus shown in FIG. 2 uses a heat seal agent as an adhesive and uses a laminate sheet 1 to which an adhesive (heat seal agent) has been applied in advance. Compared with the laminating device, the adhesive coater 7 and the dryer 8 are omitted,
A heater such as a heater is built in one or both of the pressure rollers 9. That is, the pressure roller 9 in this embodiment also serves as a heating roller. The heater is a pressure roller 9
It is not limited to those provided inside, but in short, the pressure roller 9 in a state where the heat sealing agent is heated and melted.
It may be arranged upstream of the pressure roller 9 as long as it can pass through the space.

Further, the laminate sheet 1 is not only coated with a heat-sealing agent, but also printed with predetermined items such as characters and patterns and with a marker printed at a predetermined position.

When laminating is performed by the laminating apparatus shown in FIG. 2, the laminated sheet 1 unwound from the sheet coil stand 4 is conveyed to the pressure roller 9 while being guided by the guide roller 5, and a marker is detected by a detector during the conveyance. And the position control device controls the feeder 12 and the like based on the signal from the detector to align and send the single-wafer base material 2, thereby superposing the single-wafer base material 2 at a predetermined position on the laminate sheet 1, In this superposed state, it is sent between the pressure rollers 9.

When the laminate sheet 1 and the single-wafer substrate 2 are sent between the pressure rollers 9 in a superposed state, the heat from the heater is transferred to the laminate sheet 1 via the pressure roller 9, and this heat causes a heat seal agent. Melts,
The laminated sheet 1 and the entire surface of the single-wafer substrate 2 are heat-sealed and integrated by the pressure of the pressure roller 9 (heat-sealing step).

The laminated sheet 1 that has passed between the pressure rollers 9 is conveyed to the cutting machine 10 and is cut into individual sheet base materials 2 by a cutter (cutting step).

Then, the cut sheet-shaped base materials 2 are successively conveyed one by one to the stacker 11, and the stacker 11
It is stacked and stored inside.

Since the laminated sheet 1 is laminated on the surface of the single-wafer base material 2 which has been surface-treated through the above-mentioned steps with a heat sealant, it has a sufficient gloss and the transparent laminated sheet 1 Since the predetermined items are printed on the sheet, it looks as if these items were printed on the single-wafer substrate 2. Further, in this embodiment, since the heat-sealing agent is coated on the laminating sheet 1 in advance, it is not necessary to provide a device for applying an adhesive or a dryer 8, and the structure of the laminating device itself can be simplified. .

In the above-mentioned two embodiments, the laminate sheet 1 on which the predetermined items and markers are printed in advance is used, but this printing may be transfer printing. A printing process may be included as a pre-process of the series of laminating processes described above. That is, a printing step of printing a predetermined item on the laminate sheet 1 while the laminate sheet 1 is being conveyed and printing a marker at a predetermined position may be included inline.

For example, in the apparatus shown in FIG. 3, the flexographic printing machine 17 is provided in the conveying path 6 on the downstream side of the sheet coil stand 4.
An adhesive coater 7, a dryer 8, a pressure roller 9, a cutting machine 10, a stacker 11 and the like are provided on the conveying path 6 on the downstream side of the flexographic printing machine 17 as in the above-described embodiment. , A feeder 12 for feeding the single-wafer substrate 2
There is also a position control device.

Therefore, in order to perform the laminating process in the apparatus shown in FIG. 3, first, the long laminated sheet 1 unwound from the sheet coil stand 4 is hung over the guide roller 5 and the operation is started in this state. While the laminated sheet 1 sent out from the sheet coil stand 4 passes through the flexographic printing machine 17, a predetermined description item is printed and a marker is printed at a predetermined position (printing step).

The laminated sheet 1 printed by the printing machine 17 is conveyed to the adhesive coater 7 provided on the downstream side, and a liquid adhesive is applied to one surface thereof (adhesive applying step).

The laminate sheet 1 which has undergone the adhesive application process is conveyed to the dryer 8 while being guided by the guide rollers 5, and the adhesive of the laminate sheet 1 is dried while passing through the dryer 8 (drying). Process).

The laminate sheet 1 which has passed through the dryer 8 is conveyed while being guided by the guide rollers 5, and is fed between the pressure rollers 9 in a state where the sheet base material 2 is superposed on the adhesive application surface. A detector of a position control device is arranged on the upstream side of the pressure roller 9, and this detector is used for the laminate sheet 1.
Marker is detected, and the feeder 12 aligns the single-wafer substrate 2 based on the signal from the detector and sends it out. Therefore, the single-wafer substrate 2 sent from the feeder 12
When the sheet is conveyed by the conveying means and overlaps with the laminate sheet 1, the sheet base material 2 is overlapped at a predetermined position of the laminate sheet 1, and in this overlapped state, both of them are pressed by the pressure roller 9
After passing through the space, they are pressure-bonded by the pressure of the pressure roller 9 and bonded by an adhesive (bonding step).

The laminated sheet 1 that has passed between the pressure rollers 9 is conveyed to the cutting machine 10, and the laminated sheet 1 conveyed to the cutting machine 10 is cut into individual sheet base materials 2 by a cutter (cutting step).

Then, the cut sheet-shaped base materials 2 are successively conveyed one by one to the stacker 11, and the stacker 11
It is stacked and stored inside.

In this way, when the printing machine 17 is arranged in the laminating line to make the printing process in-line,
Not only the efficiency can be remarkably improved, but also it is not necessary to transport the laminated sheet 1 from the printing factory to the surface processing factory, and the work-in-process can be eliminated, which is rational.

The printing process included in the laminating line is not limited to the above-mentioned flexographic printing machine, and any printing machine may be used. For example, an offset printing machine as shown in FIG. 4 or a gravure printing machine as shown in FIG. 5 may be provided in the conveyance path 6 of the laminate sheet 1, or may be a rotor screen printing machine.

The printing of the predetermined items in the present invention is
It includes a wide range of printing from solid clear to colored ink and solid printing to ordinary design printing.

[0042]

As described above, according to the present invention, it is necessary to print a predetermined description such as characters and patterns on a laminated sheet, and to laminate the laminated sheet so that it is laminated on the laminated sheet. Absent. Therefore,
Even if the sheet-shaped substrate is made of a material or a form which is not suitable for printing, it looks like a natural state after being laminated and printed on the sheet-shaped substrate.

Further, since it is not necessary to print on the single-wafer substrate, the unevenness of the printing ink is not generated on the single-wafer substrate, and the blocking prevention powder is not attached, so that the processing speed is slowed down and the adhesive such as an adhesive is not used. It is not necessary to increase the coating material. Therefore, the processing speed can be increased, the efficiency can be improved, the quality can be improved, and the processing cost can be reduced.
