DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention relates to a method of laminating an object to be laminated by sandwiching the object to be laminated between upper and lower thermally responsive laminate films and applying pressure and heat. The present invention relates to a laminating apparatus for performing a lamination process by sealing with a film.

(B) Conventional technology Conventionally, there has been known a laminating apparatus in which the front and back surfaces of a sheet-like laminating object are wrapped in a laminate film, sealed and laminated to improve the appearance and the storability of the laminating object.

 FIG. 7 shows an example of a conventional laminating apparatus.

In the figure, an upper laminate film roll 101a formed by winding a heat-reactive upper laminate film 102a and a lower laminate film roll 101b formed by winding a lower laminate film 102b are disposed in the apparatus main body 100, respectively. ing. The laminated films 102a and 102b peeled off from the laminated film rolls 101a and 101b are wound around the pressure / heating rollers 103a and 103b that are in pressure contact with each other, and are pulled and overlapped with the pull rollers 105a and 105a, respectively. The tension is given by 105b. Heaters 106a and 106b for heating the pressurizing and heating rollers 103a and 103b, respectively, are housed inside the rollers, respectively.

Paper feed table 1 provided upstream of pressure / heat roller pair 103
From 09, the lamination target 110 is set and inserted into the nip of the pair of heating rollers 103a, 103b, which is the junction of the upper and lower laminated films 102a, 102b. The object to be laminated 110 is sandwiched by being pressed and heated by a pair of pressing and heating rollers 103 so as to be wrapped by the upper and lower laminated films 102a and 102b, and conveyed outside the machine by a pair of pull rollers 105. The rear ends of the laminated films 102a and 102b and the object to be laminated 110 are cut by a cutter unit 111 provided on the downstream side of the pull roller pair 105.

An operation unit 113 is provided at an upper portion of the apparatus main body 100. The operation unit 113 is provided with the laminate films 102a and 102b.
Switches 115 and 116 for manually setting the transport speed of the pull roller pair 105 and the outer peripheral temperature of the pressurizing / heating roller pair 103 are provided.

(C) Problems to be Solved by the Invention However, in the above-described conventional laminating apparatus, since the film is cut manually by the user at the end of lamination on the object to be laminated, the following is required. There were drawbacks.

Since the position where the laminate film is cut varies depending on the object to be laminated, the size of the laminate sheet tends to be irregular in the finished state.

Since the cutting of the leading end of the laminated film is performed by the user after the laminating process, the laminating operation is troublesome twice.

Since the cutter for cutting the laminate film is disposed outside the apparatus so as to be exposed, the user may be injured.

Some conventional laminating machines cut the leading and trailing edges of the film of the object automatically laminated, but the laminating is performed on each of the laminated objects and the leading and trailing edges are cut. There is no function of laminating objects that are continuously conveyed together and cutting the leading and trailing ends of the continuous objects.

Therefore, an object of the present invention is to provide a laminating apparatus capable of automatically cutting the leading and trailing ends of a laminated film. It is another object of the present invention to provide a laminating apparatus capable of laminating continuously transported objects together and cutting the leading and trailing ends of a film in which the objects are laminated together.

(D) Means for Solving the Problems The present invention conveys an object to be laminated sandwiched between upper and lower thermally responsive laminate films, and presses and compresses the object.
In a laminating apparatus for laminating an object by heating, a detecting means for detecting the object to be laminated, a conveying means for conveying the object sandwiched between the laminate films, and a rear end of the object Rear-end detecting means for detecting, film-cutting means for cutting the laminated film while sandwiching the object, and control means for controlling a cutting operation of the film-cutting means according to a detection signal of the rear-end detecting means; The control means, when starting the operation of the film cutting means,
When a new object is detected by the detecting means, control is performed so that the film cutting means is not operated until the detection signal from the detecting means is no longer input.

(E) Operation Based on the above configuration, the rear end of the object to be conveyed is detected by the rear end detection unit, and the control unit operates the film cutting unit in response to the detection signal from the rear end detection unit. Then, the laminate film is cut with the object sandwiched. When a new object is detected by the detecting means when the operation of the film cutting means is started, the film cutting means is not operated until the detection signal from the detecting means is no longer input.

FIG. 5 shows a flowchart according to the second embodiment of the present invention.

In the document detection means, the document (laminated object 20)
Is detected (S100), the conveyance of the original and the laminated film is started (S101). The CUT timer is started when the trailing edge of this document has passed through the document detection sensor (S10
2). If the time is not up, the transport motor is always kept ON.

Then, when the time of the CUT timer is up, the document is confirmed (S105). If not, stop the motor (S10
6). The cutter motor is turned on, and the rear end of the film is cut (S107). After that, the CUT timer is cleared and the cutter motor is turned off. Turn on the transport motor again, start the paper discharge timer, and when the time is up, turn off the transport motor and CUT
And discharge the film. Then, the process returns to the document waiting state again (S100).

However, if it is determined in S105 that there is a next original, the process returns to S101 and waits for the second original without turning off the transport motor (S102). When the trailing edge of the second document is detected, the same processing as described above is performed and the cut film is discharged. In this embodiment, the cut position of the film is determined by the timer, but the cut position can be similarly controlled by feeding back a signal from the pulse detecting means. The cutter motor is operated at a time of 100 ms plus (plus 10 pulses in the number of pulses) for a predetermined time (predetermined pulse) from the detection of the trailing edge of the document to the cutter position, and the margin is cut on the film (margin) About 10mm). Further, the transport motor is stopped at the time of rear end cutting, but this is not a limitation.

In the second embodiment, the trailing edge of the recording paper is cut, but in the present embodiment, the cutting of the leading edge will be described.
FIG. 6 shows a flowchart of this embodiment. First, as in the previous embodiment, when a document is detected, the conveyance motor is turned on (S202), and then the CUT timer is started (S203).
When the predetermined time has come, turn on the cutter motor (S20
5) If cut, clear the CUT timer (S207)
Turn off the UT motor. Thereafter, the rear end is cut and discharged in the same manner as in the above embodiment. In this embodiment, the operation is performed for a predetermined time. However, as in the first embodiment, it is possible to control the film cutting unit by feeding back the signal from the pulse detection unit. After detecting the leading edge of the original and driving the transport motor, the cutter motor is operated at a time of minus 100 msec (minus 10 pulses in number of pulses) within a predetermined time (predetermined pulse) to the cutter position. Create a margin area (about 10mm margin area).

(G) Effects of the Invention According to the present invention, a means for detecting the trailing edge of a document (object to be laminated) is provided, and a plurality of timer means are operated in accordance with these signals, thereby leading and trailing the laminated film. The end can be cut automatically. In addition, a laminating apparatus that can laminate continuously transported objects together and automatically cuts the leading and trailing ends of a film that is laminated together with continuously transported objects Can be provided.
