Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus for sealing a material to be laminated with a laminating film (so-called laminating), and more particularly to a laminating apparatus capable of accurately receiving the laminating film.

[0002]

2. Description of the Related Art Conventionally, a laminating apparatus has an identification card,
A sheet-shaped or card-shaped medium such as a medical examination ticket, a photograph, or a commuter ticket is laminated with a laminating film.

The laminating apparatus is mainly composed of a conveying section for conveying a laminated film sandwiching a medium together with the medium in a guide path, a heating section for heating the laminated film conveyed in the guide path for sandwiching the medium, and a heating section. It is composed of a pressure-bonding section that pressurizes the heated laminated film from both sides to bring the laminated film and the medium into close contact with each other.

The laminated film is formed by applying a heat-reactive adhesive, which improves adhesiveness when heated, to one side of a plastic film. Therefore, when the laminated film is heated, the plastic film adheres to the medium with the adhesive to protect the laminated film from dirt, rubbing, damage and the like when the medium is used.

Typical heating methods for laminating films include a plate heater method and a roll heater method.

The plate heater system has a heating unit having a heating plate disposed on the upstream side of the pressure-bonding unit so as to sandwich the front and back sides of the medium with a predetermined gap therebetween, and a heater attached to the outside of the heating plate to heat the heating plate. This is a method of directly heating the laminated film. Note that the roll heater method is a method that is not related to the present invention, and a description thereof will be omitted.

FIG. 9 is a main sectional view of a plate heater type laminating apparatus.

Description of Laminating Device Configuration The main body 100 of the laminating device 101 has an insertion port 4 and
The discharge port 5 is formed. The path 12 from the insertion port 4 to the discharge port 5 is linearly formed. Insertion guide 8
Reference numerals a and 8b guide the laminated film 1 from the insertion port 4 to the pair of feed rollers 6a and 6b. The pair of feed rollers 6 a and 6 b feed the laminated film 1 to the heating unit 10.

The heating unit 10 is arranged between the pair of feed rollers 6a and 6b and the pair of pressure-bonding rollers 7a and 7b which will be described later. The heating unit 10 includes a heating plate 10a, an insulating material 10b, a heater 10c, and the like, which are vertically paired with the path 12 in between.

An aluminum plate is used as the heating plate 10a. The heating plates 10a, 10a are arranged with a predetermined gap so as to sandwich the upper and lower sides of the laminate film 1 to heat the laminate film 1 from both sides, and at the same time from the feed roller pair 6a, 6b to the pressure roller pair 7a, 7
It will guide you to b. As the heater 10c, a resistance heating heater using a nichrome wire is used. The heater 10c is attached to the back side of the surface of the heating plate 10a facing the laminate film 1 via an insulating material 10b.

The pressure roller pair 7a, 7b presses the laminated film 1 heated by the heating unit 10 onto the medium 2 and conveys it. The discharge guides 9a and 9b guide the laminate sheet pressure-bonded by the pressure roller pair 7a and 7b to the discharge port 5.

Description of the operation of the laminating apparatus When power is applied to the main body 100 of the laminating apparatus 101, electric power is supplied to the heater 10c from a power supply section (not shown), and the heater 10c generates heat. Then, the heating plate 10
a begins to be heated. Further, the feed roller pair 6a, 6b
Then, a motor (not shown) for driving the pressure roller pair 7a, 7b is started.

After the temperature of the heating plate 10a rises to reach the laminating temperature of about 120 degrees, the user inserts the laminating film 1 holding the medium 2 from the insertion port 4 into the insertion guide 8.
It is inserted along a and 8b until it is nipped by the nip of the feed roller pair 6a and 6b. The laminated film 1 sandwiching the medium 2 is conveyed by the pair of feed rollers 6a and 6b and passes through the heating unit 10 at a constant speed while the heating unit 10
Is heated sufficiently and is sent to the pressure roller pair 7a, 7b.

The pressure roller pair 7a, 7b is generally a rubber roller. The pressure roller pair 7a, 7b presses the laminate film 1 onto the medium 2 and discharges the guides 9a, 9b.

Description of Operation of Laminating Device Before inserting the laminated film 1 with the medium 2 sandwiched in the insertion port 4, the user adjusts the pair of left and right laminated film side regulating members 40 to the width size of the laminated film. Thereafter, the user guides the pair of left and right laminated film side regulating members 40 and inserts the laminated film 1 straight until it hits the nip of the pair of feed rollers 6a and 6b. The laminated film 1 inserted into the insertion port 4 pushes down the sensor lever 31 of the detection unit 13 to turn on the photo interrupter 30.

In the laminating apparatus 90 of this embodiment, the controller 80 feeds the photo interrupter 30 after turning on the photo interrupter 30 and after a predetermined time elapses until the leading edge of the laminate film 1 reaches the nip of the pair of feed rollers 6a and 6b. The roller pair 6a, 6b is adapted to rotate. Therefore, the laminating apparatus 90 is configured to convey the laminated film 1 after the leading end of the laminated film 1 is uniformly pressed in the width direction to the nip of the pair of feed rollers 6a and 6b as shown in FIG. There is.

As shown in FIG. 4, the insertion blocking portion 50a of the shutter lever 50 is provided at the front end 1a of the laminate film 1.

The inclined surface 50ba of the discharge pressing portion 50b is still pressed against the laminated film 1. Therefore, the shutter lever 50 further rotates clockwise and tends to tilt. However, the shutter lever 50 has the insertion blocking portion 50a.
Is in contact with the lower surface of the laminated film 1, and therefore cannot rotate and tilt in the clockwise direction. Therefore, the shutter lever 50 bends and elastically deforms at the portion of the lever arm portion 50d that is elongated.

Further, when the laminated film 1 is conveyed, the state shown in FIG. 5 is passed, and as shown in FIG. 6, when the rear end 1b of the laminated film 1 passes through the insertion blocking portion 50a of the shutter lever 50, the shutter is released. The elastic deformation of the bent arm portion 50d of the lever 50 is released, and the insertion blocking portion 5 is released.
0a instantly becomes the slit 18 of the insertion guide 18b.
It also enters ba and is in a state of completely passing through the path 12.

The insertion blocking portion 50a shields the insertion opening 4 until the rear end 1b of the laminated film 1 passes through the ejection pressing portion 50b, and inserts the subsequent laminated film until the ejection of the preceding laminated film is completed. Surely prevent. When the rear end 1b of the laminate film 1 passes through the discharge pressing portion 50b, the discharge pressing portion 50b is released from the state of being pressed by the laminate film 1. Therefore, in the shutter lever 50, as shown in FIG. 1, the discharge pressing portion 50b has the through holes 19a of the discharge guides 19a and 19b.
It returns to the state of penetrating a and 19ba and protruding into the path 12, and becomes the standby state.

In this case, the two pieces 51a and 51b are urged by the spring 51d in the direction of projecting to the path 12, but the insertion blocking piece 51a is received by the stopper pin 51e integrated with the discharge pressing piece 51b, and the opening angle between them is increased. Is regulated.

In this shutter mechanism 51, when the inclined portion 51ba of the discharge pressing piece 51b is pressed by the laminate film 1, the insertion blocking piece 51a is changed to the laminate film 1.
The spring 51d elastically deforms. When the rear end 1b of the laminated film 1 passes through the insertion blocking piece 51a,
The elastic deformation of the spring 51d is released, and the insertion blocking piece 51a is released.
Instantly inserts slits 18a in the insertion guides 18a, 18b
It is prevented that the subsequent laminated film 1 is inserted into the insertion opening 4 by penetrating through a and 18ba.

The rear end 1b of the laminated film 1
When the sheet passes through the discharge pressing piece 51b, the insertion blocking piece 51a and the discharge pressing piece 51b return to their original positions by their own weights, and the discharge pressing piece 51b passes through the through holes 1 of the discharge guides 19a, 19b.
It returns to the state of penetrating 9aa and 19ba and protruding into the path 12, and enters the standby state.

Further, although the shutter lever 50 and the shutter mechanism 51 mechanically block the continuous insertion of the subsequent laminated film, like the insertion blocker (insertion blocker) 85 shown in FIG. The continuous control of the subsequent laminated film may be prevented by the physical control.

This insertion preventing device 85 is composed of the feed roller pair 6
Only a and 6b are connected to the motor 70 via a clutch (drive connecting means) 71. In this case, the control unit 72 causes the feed roller pair 6a, 6a to move the rear end 1b of the laminated film 1 after passing the detection unit 13 to immediately after the heating unit 20 or until it reaches the discharge port 5.
By disconnecting the clutch 71 from 6b and stopping the rotation of the feed roller pairs 6a and 6b, it is possible to prevent the subsequent laminated film from being inserted until the preceding laminated film is discharged.
