Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminating apparatus, and more specifically, to a surface on which an image is recorded on an image receiving medium (medium) on which an image or the like is recorded by a recording device such as an ink jet printer, a printing machine or a copying machine. The present invention relates to a device for fixing a film on a sheet, and more particularly to a laminating device applicable to a large-sized device used for producing posters and the like.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Unexamined Patent Publication No. 2000-04336.
As shown in Japanese Patent Publication No. 8, a film having a latex layer formed on a heat-resistant base material is heated and fixed on the recording surface of a recording paper on which an image is recorded by an inkjet printer or the like, and then the heat-resistant base material is removed from the film. 2. Description of the Related Art There is known a laminating apparatus that improves color development and durability of a recorded image by covering a recording paper with a latex layer that is peeled off and finally fixed.

More specifically, a roll-shaped recording paper (image receiving medium) and a roll-shaped film (protective member) are fed together by a pair of conveying rollers, and at the same time, a pair of fixing rollers are applied to the recording surface of the recording sheet. The latex layer of the protective member is thermocompression bonded. As a result, the latex layer of the protective member melts, adheres to the recording surface, and is adhesively fixed to form a protective layer. Next, the base material is peeled off from the protective member by a winding roller and wound up, and then cut by a cutter to discharge the recording paper on which sheet-shaped recording and lamination are completed onto a discharge tray.

The film to be laminated in such a laminating apparatus is generally in the form of a web,
When the film is wrinkled, if the film is fixed to the image receiving medium as it is, the film may be fixed on the image receiving medium and wrinkles may appear on the printed matter on which the lamination is completed. Therefore, the laminating apparatus has a mechanism for applying a predetermined tension to the film before fixing,
The film is fixed without wrinkles.

As a mechanism for applying tension to the film before fixing, a predetermined brake is applied to the rotation of the core shaft of the roll accompanying the film supply in the film mounting portion that holds the roll-shaped film before being supplied to the fixing portion. It is known that a predetermined tension is applied to a film by applying a force.

On the other hand, in mounting the film roll on the core shaft in the film mounting portion, the roll is provided with a hollow tube along the center thereof, and the core shaft is passed through the hollow tube and the roll is sandwiched. This is done by fixing stoppers at both ends of the core shaft so as to hold it down.

Further, as a detailed structure for transmitting the braking force to the roll through the stopper, the applicant of the present application discloses in Japanese Patent Application No. 2000-364482 that one outer peripheral portion of the stopper is fixed to the core shaft. One key groove extending in the axial direction is provided, and also extends in the axial direction in the inside of the hollow tube which is the winding core of the film roll.
By providing two key grooves and inserting the key into the two key grooves with the stopper inserted in the roll tube, mutual movement in the rotational direction is restricted, and as a result, the braking force applied to the core shaft is reduced. We propose a structure that transmits the film to a roll-shaped film.

[0008]

However, in the roll fixing structure using the above stoppers, since the fixing positions of the stoppers at both ends of the core shaft are predetermined, the axial direction of the film roll or the tube which is the core of the film roll. If there is variation in the dimension along the pipe, the fixing by the stopper may damage the pipe or the like.

For example, the above-mentioned tube, which is the core of the roll, is often made of paper, and the dimension may expand or contract due to dimensional variations in processing the paper tube and environmental changes, especially changes in humidity. If the stopper is forcibly fixed, the paper tube itself or its key groove portion may be deformed, and in the worst case, it may be broken.

Further, the braking force applied to the core shaft of the roll is transmitted to the roll by the engagement between the key and the key groove formed in the paper tube as described above. The keyway may be damaged by the braking force acting on the keyway of the paper tube. And
Such damage to the key groove may occur in the case where proper tension action on the roll cannot be guaranteed, and as a result, wrinkles may occur on the laminated recorded matter as described above.

The present invention has been made to solve the above problems, and an object of the present invention is to install a roll-shaped film and supply the film from the core of a film roll. It is an object of the present invention to provide a laminating apparatus capable of always exerting a good tension on a film without causing damage to the tube or the like due to the mounting even if the tube has dimensional variations.

[0012]

Therefore, according to the present invention,
In a laminating apparatus for supplying a roll-shaped film and fixing the film to an image receiving medium, a film holding means for holding the roll-shaped film, a core for winding the film into the roll-shaped film A film holding means having two fixing members for holding the two by sandwiching and fixing them at both ends thereof, and having two fixing members capable of adjusting their intervals according to the length of the winding core to be sandwiched, A transporting means for transporting the film held by the film holding means and a transporting means for feeding the film from the film holding means by the transporting means, a predetermined film is fed to the film through the film holding means. And a braking force applying means for applying a braking force.

Preferably, the film holding means further has a core shaft that is passed through the hollow portion of the winding core, and one of the two fixing members is fixed to a predetermined position of the core shaft. A first stopper inserted into the hollow portion of the winding core and a first fixing ring abutting against the end portion of the winding core, and the other of the two fixing members is provided on the core shaft. A second stopper, each of which is movable, has a threaded portion and is inserted into the hollow portion of the winding core; a second fixing ring that engages with the stopper and abuts against an end portion of the winding core; 2 with stopper
An adjustment ring having a threaded portion that sandwiches a fixing ring and engages with a threaded portion of the second stopper; and a movement of the second stopper on the core shaft when the adjustment ring is fastened by the screw. And a pin provided on the core shaft.

More preferably, a plurality of key grooves are provided on the inner surface of the hollow portion of the second stopper and the winding core, respectively, and a plurality of key grooves of the second stopper and the winding core are provided on the second fixing ring. By providing a plurality of keys to be engaged with each other, the braking force can be applied.

According to the above construction, the two fixing members for holding the roll-shaped film by sandwiching and fixing the core of the roll-shaped film at both ends,
Since the interval between them can be adjusted according to the length of the winding core to be sandwiched, the winding core can be sandwiched and fixed according to the length of the winding core.

Further, since a plurality of key grooves are provided in each of the stopper and the winding core which constitute the above-mentioned fixing member and a plurality of keys of the fixing ring which engage with these key grooves are also provided, it is possible to interpose these key grooves and the like. The force acting on one key groove of the winding core when the braking force is transmitted to the film can be dispersed and reduced.

Roller support plates 604 are provided at both ends of 3,
And both ends and the drive gear 5a ₂ of the upper fixing roller 5a through bearings 604a support, supports the entire upper fixing roller 5a by the roller support plate 604. Further, heater support portions 602 and 602 are disposed on both ends of the roller case 603 and the side surface side of the roller support plate 604,
Both ends are supported by the heater supporting portions 602 and 602, and the heater 610 is arranged at the center of the upper fixing roller 5a.

A thermoswitch 611 is arranged at one end between the inside of the roller case 603 and the upper fixing roller 5a for the purpose of stopping the application of the electric current to the heater 610 when the heater 610 runs away. Thermistors 612 and 612 for measuring the temperature are arranged at the other end. Between the inner and the upper fixing roller 5a of the roller case 603, a cleaning pad 16 for contacting over the entire axial direction of the surface layer 5a ₁ of the upper fixing roller 5a (FIG. 4
Refer to the thermo switch 611 and the thermistor 612.
The roller case 603 is arranged so as not to overlap with the above so as to be insertable through a gap (not shown) of the roller case 603.

The upper fixing roller unit 600 can be taken out upward by opening the cover 23 on the upper surface of the apparatus main body 100, and can be easily taken out by gripping the handles 601 and 601. Further, when taking out, the rotating plate 520 of the fourth drive control unit 500 described above is used.
By moving in the direction of arrow O, the upper fixing roller unit 600 can be taken out. When the fixing upper roller unit 600 is inserted from the cover 23 and placed after the work such as maintenance is completed, the fixing upper roller 5a is installed. Further, as described above, when the laminating apparatus 1 is driven, the rotating plate 520 is driven in the arrow N direction, and the fourth plate
The drive controller 500 and the upper fixing roller 5a are automatically engaged.

Next, the upper fixing roller 5a and the lower fixing roller 5
b and the shapes of the main conveyance roller 7a are shown in FIGS.
Will be described with reference to. 12 is a schematic front view for explaining the shape of the upper fixing roller, FIG. 13 is a schematic front view for explaining the shape of the lower fixing roller, and FIG. 14 is a schematic front view for explaining the shape of the main conveying roller. Is.

As shown in FIG. 12, the upper fixing roller 5a is formed in a cylindrical shape having substantially the same diameter from both end portions to the central portion. As shown in FIG. 13, the lower fixing roller 5b is formed in a middle-height shape in which the central portion has a larger diameter than both end portions. As shown in FIG. 14, the main transport roller 7a is formed in a middle concave shape in which both end portions have a larger diameter than the central portion. Note that the shapes of the rollers shown in FIGS. 12, 13 and 14 are exaggerated for convenience of explanation, and particularly, the lower fixing roller 5b and the conveyance main roller 7a are centered with respect to both end portions. The part is formed to have a predetermined (for example, 0.5 mm to 2.0 mm) middle height or a middle concave shape.

Since each roller is supported by both ends, the weight of the roller may cause the entire roller to slightly bend downward and the central portion to be recessed. Therefore, in the fixing roller pair 5, for example, the fixing upper roller 5
When a and the lower fixing roller 5b are formed to have the same diameter, unevenness occurs at both end portions and the central portion when the image receiving medium 101 and the film 102 are pressed and heated for fixing.
Therefore, by forming the lower fixing roller 5b into a predetermined middle-height shape, the image receiving medium 101 and the film 10 can be substantially evenly formed.
2 and 2 are pressed and heated so that they can be fixed. On the other hand, in the conveyance main roller 7a, when a predetermined tension is applied to the laminated product 104 between the fixing roller pair 5 and the conveyance roller pair 7, for example, when the conveyance main roller 7a is formed to have the same diameter or a middle height, Laminated product 10
The tension of the central portion of 4 becomes larger than the tension of both end portions, and there is a possibility that wrinkles may be generated in the vicinity of both end portions especially when fixing is performed by pressurizing and heating. Therefore, by forming the main transport roller 7a in a predetermined concave shape, the laminated product 10
It is possible to apply a substantially uniform predetermined tension to No. 4. Then, by making the shape of each roller such a shape, it is possible to prevent wrinkles from occurring.

Next, the structure of the cutter section is shown in FIG.
A description will be given with reference to (a) and (b). FIG. 15 (a) and
(b) is a figure which shows the cutter part 700, the same figure (a) is the top view, (b) is the rear view. The cutter unit 700 is disposed between the discharge roller pair 8 and the discharge port 61 (see FIG. 4), and has a cutter holder 701 and a rail 70.
2 and a fifth drive control unit 703.

The cutter holder 701 is provided on the cutter table 710, and has cutters C1 and C1 having a circular blade shape in the cutter holder 701. The cutter holder 701 and the cutter base 710 are arranged on a rail 702 provided in the width direction of the passing film 102 so as to be movable in the arrow PQ direction in the figure. For example, the cutter holder 701 and the cutter base 710 are shown by solid lines. The film 102 is cut in the width direction by moving from the position indicated by (1) to the position indicated by the two-dot chain line in the figure, that is, by moving the film 102 over the entire width thereof. Note that the film 102 can also be cut by moving in the opposite direction.

On the other hand, below the rail 702, a fifth drive control section 703 is arranged, and the fifth drive control section 7 is provided.
03 has a substrate 711 fixed to the rail 702. A motor M5 is arranged at a lower portion of one end of the board 711, and the motor M5 is connected to a control unit (not shown) via a wiring 706. A drive gear 704 and a drive gear 705 are arranged on the substrate 711, and when the drive gear 704 is rotated by the motor M5, the drive gear 705 rotates. Here, the drive gear 705 has wires 7 supported by pulleys 707 and 707.
08 is wrapped around this wire 708
On the opposite side of the drive gear 705, the cutter base 710 is engaged. As a result, the drive gear 70
When 5 rotates, the wire 708 is pulled and the cutter table 710 moves. Sensors 709 and 709 are arranged at both ends across the rail 702 and the substrate 711. The sensors 709 and 709 are provided on the cutter table 7
It is detected that 10 has moved to the direction of arrow PQ and reached the end, and sends a predetermined signal to the control unit (not shown) via wirings 709a and 709a.

When the cutter unit 700 cuts the film 102, first, the sensor 709 is used to cut the cutter table 71.
The position 0 (the position at the left end or the position at the right end in the drawing) is detected, and the rotation direction of the motor M5 is controlled and driven by the control unit (not shown). As a result, the drive gear 7
The wire 708 is driven in the direction of arrow P or Q through 04 and 705, and the cutter table 710 moves from one end to the other end. When the cutter table 710 reaches the other end, the sensor 709 detects and sends a predetermined signal to a control unit (not shown), and the driving of the motor M5 is stopped via the control unit. That is, the cutter C1 of the cutter holder 701 is moved from one end to the other end to cut the film 102 in the width direction.

Next, the detailed structure of the film mounting portion 20 of this embodiment will be described with reference to FIGS.

FIG. 16 shows a sixth drive control section (brake device) 800 which is a brake mechanism of the film set 103 including the film roll, which is mounted on the film mounting section 20.
17A is a side view, FIG. 17A is a plan view showing a fixing portion 900 that fixes the film set 103, and FIG. 17B is a partial broken surface showing details of the stopper 902, the fixing ring 902a, and the adjusting ring 907. FIG. 17 (c) is a perspective view showing it in a further disassembled state. 18 (a) to 18 (g) are views showing the setting operation of the film set (film roll) 103 in the order of operation, and FIG. 19 is a side view showing the tilting cam mechanism (continuous swinging means) 850 of the film mounting portion 20. 20 is a plan view of FIG.

As shown in FIG. 16, the brake mechanism of the film mounting portion 20 is entirely covered by a cover 21 which is swingable in the direction of arrow HI via a fulcrum 22, and below the cover 21. At the device main body 100
A sixth drive control unit 800 serving as a brake mechanism of the film set 103 is arranged inside. The sixth drive control unit 800 has a substrate 801, and a brake B2 is arranged on this substrate 801. Further, a drive gear 802 and a drive gear 803 that engage the brake B2 and the dock 821 are arranged on the substrate 801. Dock 8
21 is a core shaft 901 of the film set 103 (see FIG.
The shaft 8 is engaged with the dock 905 arranged in (a)).
It is arranged on 20. That is, the brake force is applied to the core shaft 901 of the film set 103 by controlling the brake of the dock 821 by the brake B2. This makes it possible to apply a predetermined tension to the film 102 (see FIG. 4) supplied by rotating the film set (film roll), and prevent the web-shaped film 102 from wrinkling.

As shown in FIG. 17A, the fixing portion 900 for fixing the film set 103 has a core shaft 901, and the core shaft 901 is arranged along the central axis of the film set 103 when the film set 103 is mounted. It is inserted into the hollow portion of the provided paper tube. On the other hand, both ends of the core shaft 901 are supported and fixed by supporting portions 910 and 911 fixed to the apparatus main body 100. When the roll-shaped film set 103 is mounted on the paper tube by inserting the core shaft 901 into the paper tube as described above, stoppers 902 and 903 are mounted on both ends of the core shaft 901. Thereby, the axial movement of the core shaft 901 of the film set 103 can be restricted.

More specifically, the stoppers 902 and 903 are provided with through holes, and the core shaft 90 is passed through these through holes.
1 and engages with it. The stopper 903 on the left side in FIG. 17A is basically movable along the core shaft 901, but a fixing ring 903a having a C-shaped spring property is formed at a predetermined position of the core shaft 901. The ring is engaged with and fixed in the groove, and the movement in the axial direction, that is, to the left in the drawing is restricted by hitting this ring.

On the other hand, the stopper 902 on the right side is basically also movable along the core shaft 901. However, since the two fixing pins 902c for restricting the rightward movement of the stopper 902 are provided on the core shaft 901 so as to be shifted from each other by 180 degrees, the through groove 9 for avoiding the interference with the fixing pins 902c is provided.
By providing 02d, it is possible to move freely.

As shown in FIGS. 17B and 17C, the stopper 902 on the right side constitutes a fixing mechanism of the film set 103 together with the fixing ring 902a and the adjusting ring 907.

That is, the stopper 902 is provided with key grooves 902b at two locations on its outer peripheral surface, in addition to the above-described through groove 902d provided in the through hole. In addition, a screw portion is provided at one end. In addition, the fixing ring 902a
In addition to the hole for inserting the core shaft 901, a pair of keys 9
02ak is provided. The key 902ak is used for the key groove 902b of the stopper 902 and the film set 10.
When 3 is mounted, it engages with two key grooves provided inside the tube which is the core thereof. Further, the adjusting ring 907 is provided with a thread inside thereof, which engages with the threaded portion of the stopper 902.

Film set 10 by the above fixing mechanism
The fixing of No. 3 will be described. The core shaft 901 is inserted into the hollow portion of the paper tube which is the winding core of the film set 103 in a state of being removed from the supporting portions 910 and 911 of the present apparatus. Then, the left stopper 903 and the fixing ring 903a are attached to the core shaft 901 as described above. Next, the right side stopper 902 is also attached to the core shaft 901 in the same manner, and the film set 1
No. 03 paper core and fixing ring 902a
Is abutted against the end of the paper tube, and then fixed with the screw of the adjustment ring 907.

At this time, as described above, the length of the paper tube may vary due to manufacturing errors or environmental changes. In this embodiment, the fixing ring 902a moves in the axial direction and can take a position according to this variation. Then, the adjusting ring 907 is rotated at this position to perform the screw fastening operation. At this time, the position of the stopper 902 and the core shaft 901 in the rotating direction is a position rotated by 90 degrees from the position where the fixing pin 601c on the core shaft 901 and the through groove 902d of the stopper 902 engage, and the fixing pin 901c is rotated. Is at a position where it can be engaged with two fixing grooves 902e provided on the inner surface of the through hole of the stopper 902. Then, by the fastening operation by the rotation of the adjustment ring 907, the fixing ring 902a abuts on the end surface of the paper tube of the film set 103, and the stopper 902 is pulled to the right side in FIG. 17 (b), and the end of the fixing groove 902e thereof. Part moves until it comes into contact with the fixing pin 901c on the core shaft 901,
Form a fixed relationship. As a result, the film set 103
Will be fixed with appropriate force. The fixing groove 902e provided in the stopper 902 is
As will be described later with reference to FIG. 18, the fixing pin 901c for fixing and the fixing groove 902e can be engaged by pre-aligning the fixing pin 901c of the core shaft 901 during this fixing operation. Becomes

As described above, even if the length of the tube, which is the core of the roll-shaped film set, varies due to the mechanism in which the fixing ring 902a is movable and is fixed by using the adjusting ring 907, this is performed with an appropriate force. Can be fixed, for example, the tube itself can be forcibly attached to damage the tube, and as a result, proper tension cannot be applied to the film to be supplied.

In the fixing mechanism described above, the key engaging with the key groove of the paper core of the film set is the fixing ring 902.
The two keys 902 a of ‘a’ correspond to the distribution of the force acting on the keyway of the paper tube when transmitting the braking force to the film set, as compared with the case where one key is engaged. The force exerted by the key on the paper core can be reduced. This also makes it possible to reduce damage to the paper tube.

There are two types of film sets to be set in this apparatus, the width being 38 inches and the width being 46 inches.
Therefore, the core shaft 901 is provided with a pair of fixing pins 902c at two positions in the axial direction. FIG. 17A shows a case where a 38-inch wide film set is mounted, and the 46-inch fixing pin 902c seems to project from the core shaft 901.
Needless to say, when the stopper 902 is moved to a position corresponding to 46 inches, the 38-inch fixing pin 902c appears to project.

FIGS. 18 (a) to 18 (g) are views showing a display example for the operator for explaining the exchange work of the above two kinds of films.

FIG. 18A shows the fixed positions of 38 inches and 46 inches. In the case of this apparatus, since the transport system is designed with the central reference, each of the fixing rings 902a and 903a is moved to the position shown in FIG. 4A when changing the width of the film to be mounted. Therefore, similar to the fixing pin 902c, the groove of the core shaft 901 that engages with the left side fixing ring 903a is also received at two positions according to the above position.

FIG. 18B shows the work for moving the stopper 902. The groove 902d in the stopper 902 includes the stopper 902 and a fixing ring 902a integral with the stopper 902, and "Release" described above.
By aligning with the position of "e", it becomes a position where it can be engaged with the fixing pin 902c, which enables the movement in the axial direction. On the other hand, after the movement, as shown in FIG. 18C, the fixing pin 902c is moved to the stopper 90 corresponding to the "Lock" position.
It is aligned with the second fixing groove 902e.

FIG. 18D illustrates the work of aligning the position of the fixing ring 902a in the axial direction of the stopper 902. As described above, when the length of the paper core, which is the winding core, varies, in FIG.
3a cannot be fixed. In this case, in FIG. 18 (d), by rotating the adjustment ring 907 in the direction of the arrow in the figure, the fixing ring 902a can be moved to the right in FIG. 17 (b), and the axial dimension expands. The set can be fixed. FIG. 18 (e) relates to the work of setting the film. As described above, the paper tube 103a of the film set is provided with two key grooves at one end (at a 180 ° symmetrical position). The key 902ak of the fixing ring 902a is engaged here, and further,
Fixing pin 902c of core shaft 901 and groove 9 of stopper 902
By setting 02d to the position of "Lock", the mounting of the film set is completed.

FIG. 18 (f) is a view for explaining a state where the adjusting ring is rotated in the direction of the arrow to perform the above-described screw fastening operation. In this case, as described above, the fixing ring 902a moves to the left side in FIG. 17B, and the fixing pin 901c and the fixing groove 902 of the stopper 902 are also moved.
Since it comes into contact with e, the film set can be fixed without rattling.

Finally, as shown in FIG. 18 (g), a film set equipped with a core shaft 901 is attached to the main body of the laminating apparatus to complete the setting.

In FIG. 17 (a), a bearing 904 is attached to one end of the core shaft 901, and a bearing 906 is attached to the other end of the core shaft 901. A dock 905 that engages with the aforementioned dock 821 is attached. The bearing 904 and the bearing 906 have different diameters. On the other hand, the supporting portions 910 and 911 for supporting the core shaft 901 provided with these dissimilarities are the opening portions 910a and 91, respectively.
11a is provided, and the bearing 9 is provided on the support portion 910.
04 is provided with a groove portion 910b having the same diameter, and the core shaft 901 is fitted and fixed from the upper front side. At this time, the support portion 9
11 has no groove, and the bearing 904 and the bearing 9
Due to the difference in diameter from 06, the bearing 904 is
Fits only 10. That is, it is possible to prevent the film set 103 from being attached to and fixed to the fixing portion 900 in the opposite directions. Further, an arrow 908 is provided at the center of the core shaft 901.
It is possible to prevent the film set 103 from being attached to the core shaft 901 in the opposite direction. Generally, the film of a laminating apparatus has a front surface and a back surface. For example, if the film is mounted upside down, the latex layer may adhere to the fixing roller, which may cause a failure of the apparatus. However, in this laminating apparatus, as described above, the film set 103
By mounting the device, it is possible to prevent the device from being installed upside down, and it is possible to prevent the device from being damaged.

As shown in FIGS. 19 and 20, the tilting cam mechanism (linking mechanism) 850 of the film mounting section 20 is disposed inside the sixth drive control section 800 in the apparatus main body 100, and the base An inclined cam 853 is rotatably arranged at 851 via a fulcrum 852. This inclined cam 85
3 includes an inclined portion 853a at one end and an arm 853b at the other end.
The arm 853b is engaged with a dock 821 that is biased in the direction of arrow U by a spring or the like (not shown) (see FIG. 20). The dock 821 has teeth 8
21a and engages with and disengages from the tooth portion 905a of the dock 905 fixed to the core shaft 901 to form a dog clutch (clutch means). On the other hand, the cover 21 is provided with a substrate 860 having a lever 861. When the cover 21 swings about the fulcrum 22 in the direction of arrow HI, the lever 861 moves around the fulcrum 22 as an arrow. It oscillates while drawing a locus 861A through the substrate 860 in the H'-I 'direction.

As shown in FIG. 19, the cover 21 has an arrow I.
When the lever 861 moves in the direction and is opened, the lever 861 moves in the direction of the arrow I ′ accordingly, and the inclined portion 853 of the inclined cam 853.
Touch and press a. As a result, as shown in FIG. 20, the inclined portion 853a is pressed and moved in the arrow R direction from the arrow S direction. And the arms 853b and 853b
Moves from the arrow U direction to the arrow T direction via the fulcrum 852 and presses the dock 821 against the urging force of a spring or the like (not shown) (that is, the inclined cam 853 prevents the lid 21 from swinging). Convert to the axial movement of the dock 821). Then, the dock 821 and the dock 905 are disengaged from each other, and the engagement between the core shaft 901 and the sixth drive control unit 800, which is a brake mechanism, is disconnected. In addition, when the laminating apparatus is actually operated, the film in the film supply path 70 is constantly tensioned by the brake B ₂ , and as a result, the dock 821 and the dock 905 are meshed with each other. However, it may not come off due to the frictional resistance. As a result, the cover 21 cannot be opened.

With respect to this, as shown in FIG. 16, the drive is transmitted from the fulcrum 22 of the cover 21 to the brake B2,
This is achieved by rotating the dock 821 in the unwinding direction (clockwise in FIG. 16). That is, the lid 2
When 1 is rotated in the direction of arrow I, the fulcrum 22 rotates clockwise. This drive is transmitted, the brake B ₂ is turned clockwise,
Further, rotate the dock 821 clockwise. This allows
The tension in the film supply path 70 is released, and the dock 82
The frictional resistance between Nos. 1 and 905 is also reduced, and it comes to come off smoothly.

Furthermore, since the gear mounted on the fulcrum 22 is engaged with the fulcrum 22 via the one-way clutch,
The drive to the cover 21 is cut off during the unwinding operation of the film during the laminating operation.

As a result, the core shaft 901 can be attached and detached, that is, the film set 103 can be attached and detached. Further, when a new film set 103 is mounted, the film set 103 is not braked, so that the film 102 can be easily supplied to the fixing roller pair 5 manually.

When the lid 21 is closed in the direction of arrow H,
Dock 821 via lever 861 and tilt cam 853
Is urged in the direction of arrow U by a spring or the like (not shown) to engage the dock 821 and the dock 905. That is, the sixth drive control unit 800, which is a brake mechanism, is engaged with the core shaft 901. As a result, the film set 103 is braked, so that a predetermined tension can be applied to the film 102 in the apparatus main body 100, and the film 102 can be stretched without wrinkles. At this time, the cover 21
The safety switch 41 described above is activated by closing the switch, and the device body 100 can be driven.

Next, the operation of the laminating apparatus based on the above configuration will be described mainly with reference to FIG. The laminating apparatus of this embodiment has a single-wafer mode in which the image receiving media 101 are processed one by one and a continuous mode in which the image receiving media 101 are continuously processed. The operation will be described in detail below.

First, the operation of the laminating apparatus in the single-wafer mode will be described. By the operator, the supply unit 20
When one end portion of the image receiving medium 101 is placed on the supply table 201 of 0 and inserted in the direction of arrow A, the image receiving medium 101 is supplied from the supply port 60 into the supply path 71. Then,
The feed sensor 10 detects the front end of the image receiving medium 101, and the control unit (not shown) drives the motor M1 shown in FIG. Then, the lower supply roller 2a and the upper supply roller 2b arranged in contact are driven through the drive gear 3b and the drive gear 3c, and when the image receiving medium 101 reaches the nip of the supply roller pair 2, it is directed toward the fixing roller pair 5. And is conveyed in the direction of arrow B. Further, when the image receiving medium 101 passes through the supply roller pair 2 and the TA sensor 11 detects the rear end of the image receiving medium 101, the drive of the motor M1 is stopped by the control unit (not shown), and the supply roller pair 2 is also driven. Stop.

On the other hand, when the film set 103 is mounted on the film mounting section 20, the film 102 is previously
Through the guide roller 4, the fixing roller pair 5, the conveying roller pair 7, and the conveying roller pair 8, up to the cutter unit 700, that is,
Film 1 in the film supply path 70 and the transport path 72
02 has been supplied. At this time, the upper fixing roller 5
a is arranged on the upper side indicated by the arrow L direction, and the film 102 is arranged so that a predetermined tension is generated by the brake B2 of the axial center of the film set 103 and the pair of conveying rollers 7 described above, and there is no wrinkle. Has been maintained. It should be noted that the film 102 of the film set 103 has a supply angle which is changed from the arrow C direction to the arrow C ′ direction in comparison with the remaining amount thereof, but the angle is aligned by the guide roller 4 and is substantially constant. It is supplied to the fixing roller pair 5 at an acute angle.

By the TA sensor 11, the image receiving medium 1
When detecting that 01 has been supplied, the control unit drives the motor M3 of the third drive control unit 420 in synchronization with the timing when the leading end of the image receiving medium 101 reaches the fixing roller pair 5, and rotates the camshaft 411. Then, the pressure arm 401 is pressed downward via the cam bracket 410.
As a result, the upper fixing roller 5a moves in the direction of arrow M and is pressed against the lower fixing roller 5b, and is fixed in that state (see FIGS. 7 and 8). Further, at this time, it is assumed that the heater 610 which is a heat source in the upper fixing roller 5a is heated to a predetermined temperature setting by the control unit.
(See FIGS. 10 and 11).

When the front end of the image receiving medium 101 is supplied to the fixing roller pair 5, the control section drives the motor M2 of the second drive control section 6 to drive the fixing roller pair 5, and the fixing roller pair 5 is driven. While fixing the image receiving medium 101 and the film 102 to form a laminated product 104, the laminated product 104 is wound around the fixing lower roller 5b at a predetermined angle and is conveyed to the conveying roller pair 7. That is, the image receiving medium 101 is fixed on an arbitrary section of the continuous film 102, and the arbitrary section of the continuous film 102 is conveyed as a laminated product 104. Further, since the lower fixing roller 5b is formed in the middle-height shape as described above (see FIG. 13), when the upper fixing roller 5a is pressed, the image receiving medium 101 and the film 102 are substantially evenly applied. It can be pressed and fixed without wrinkles. The laminated product 104 after fixing is the lower fixing roller 5
Since it is wound around b at a predetermined angle, the fixing upper roller 5a

Is sent to the control unit and displayed on the display means (not shown) of the operation panel included in the operation unit 50.

Next, the operation of the laminating apparatus in the continuous mode will be described. Since the operation in the continuous mode is substantially the same as the operation in the single-wafer mode described above, only the characteristic part will be described.

The first image receiving medium 101 is the supply unit 20.
When the first image receiving medium 101 is detected by the feed sensor 10 when it is inserted into the supply port 60 from 0, the supply roller pair 2 is driven by the first drive control unit 3 and the fixing roller pair 5 is formed. Supplied. On the other hand, the film 102
It is supplied from the film set 103 to the vicinity of the discharge port 61 in advance. When the tip of the image receiving medium 101 is supplied to the fixing roller pair 5, the fixing roller pair 5 fixes the image receiving medium 101 and the film 102, and the continuous film 102 and the image receiving medium 101 form the first laminated product 104. Form. Also, the lower fixing roller 5
b, the conveyance roller pair 7 and the discharge roller pair 8 are driven by the second drive control unit 6 to convey the laminated product 104.

Here, in the continuous mode, when the rear end of the image receiving medium 101 passes the TA sensor 11, the first
The drive of the drive control unit 3 is stopped, and the image receiving medium 1
The drive of the second drive control unit 6 is stopped at the timing when the trailing edge of 01 has finished passing the fixing roller pair 5. As a result, the first laminated product 104 remains in the transport path 72. Then, after this, the second image receiving medium 101 is inserted from the supply port 60, and the image receiving medium 1
When 01 is detected by the feed sensor 10, the drive of the first drive controller 3 is started. And the TA sensor 11
Thus, when the leading edge of the second image receiving medium 101 is detected, the driving of the second driving unit 6 is started. Next, the second image receiving medium 101 is supplied to the fixing roller pair 5, and the second image receiving is performed from a portion of the continuous film 102, which is separated from the rear end of the first laminated product 104 by a predetermined distance. The fixing of the film 102 to the medium 101 is started, and the first laminated product is discharged through the discharge port 6

The leading end of the first laminated product 1 is driven before reaching the fixing roller pair 5, whereby the first laminated product 1
Between 04 and the second laminated product 104, a section of only the film 102 is formed.

Then, when the first laminated product 104 is conveyed on the exit sensor 15 and the rear end thereof passes, the exit sensor 15 detects the section of the film 102 only. As a result, the cutter unit 700 is driven by the control unit (not shown), and the section of the film 102 alone is cut by the cutter C1. As a result, the first laminated product 104 is separated from the continuous film 102, discharged from the discharge port 61, and loaded on the discharge table 62. On the other hand, the rear end of the second image receiving medium 101 is T
When detected by the A sensor 11, the drive of the first drive controller 3 is stopped, and the second drive controller is stopped at the timing when the rear end of the second image receiving medium 101 has finished passing through the fixing roller pair 5. The drive of 6 is stopped.

After that, the above-mentioned operation is repeated to form a plurality of laminate products 104 continuously. In addition,
When cutting the film 102, the first laminated product 104 is cut from the continuous film 102 by moving the cutter C1 of the cutter unit 700 (see FIG. 15) from the P direction to the Q direction, and from the Q direction to the P direction. The second laminated product 104 is cut from the continuous film 102 by moving in the direction, and thereafter, this is repeated and cut.
Further, since the laminated product 104 is cut while being discharged, the cut end is inclined rightward or leftward when viewed from above. The continuous mode also has a mode in which the continuous laminated product 104 is discharged without cutting with the cutter C1.

First, the film 1 of the film set 103
02 is wound around a paper tube which is a winding core and is attached to the core shaft 901 so that the film 102 can be taken out in a direction of an arrow 908 marked on the core shaft, and the cover 21 is opened to set the film set. Both ends of the core shaft 901 on which 103 is mounted are fitted and mounted in the fixing portions 910 and 911 of the film mounting portion 20, and the film 102 is manually supplied so as to reach the fixing roller pair 5 (S1). At this time, since the brake B2 and the core shaft 901 are not engaged with each other by the inclined cam mechanism 850 as described above, the film 102 can be easily supplied manually.

Subsequently, the cover 21 is closed, the safety switch 41 is operated, and the apparatus main body 100 can be driven.
A feed switch (not shown) of the operation unit 50 is pressed (S

5).

At this time, the control unit operates the switch by pressing the switch while the film 102 is supplied with a predetermined tension, so that the lami sensor 13 for detecting the film 102 determines whether the film 102 has a predetermined tension or more. Whether or not it is determined (S6), if the tension is not equal to or more than the predetermined tension, the motor M2 of the second drive control unit 6 is driven for a further predetermined time (S7).
As described above, the predetermined braking force is applied to the fixing roller pair 5 by the brake B1, and when the fixing roller pair 5 and the conveying roller pair 7 are driven by the motor M2, the film 1
02 can obtain a predetermined tension. When the laminating sensor 13 determines that the film 102 has a tension equal to or higher than the predetermined tension (S6), the controller opens the pressure contact of the upper fixing roller 5a (S8). Even if the upper fixing roller 5a is opened, since the brake B2 is engaged with the film set 103 as described above, a predetermined braking force (braking force) is applied and the film 102 is maintained by a predetermined tension. . Then, the control unit stops the motor M2 of the second drive control unit 6 (S9) and completes the mounting of the film set 103 (S10).

By controlling as described above, when the film set 103 is mounted on the film mounting portion 20, the web-shaped film 102 can be tensioned by a predetermined tension without wrinkles. In addition, the film set 103 can be easily mounted on the film mounting portion 20. Further, since the film 102 is in a wrinkle-free state, even when the image receiving medium 101 and the film 102 are fixed, the wrinkle-free laminated product 104 can be obtained without fail.

The laminating apparatus according to the embodiment of the present invention has the above-described structure, operation and control. Therefore, when the cover 21 is opened when mounting the film set 103, the tilting cam mechanism 850 brakes. The engagement between B2 and the core shaft 901 is cut, and the film 102 is easily
Since it can be supplied into the apparatus main body 100, the mounting of the film 102 can be simplified. Further, in the state where the lid 21 is closed, the engagement of the brake B2 and the core shaft 901 is connected by the inclined cam mechanism 850, and a braking force acts on the film 102 in the apparatus main body 100 to give a predetermined tension. be able to. Thereby, the web-shaped film 102 is made wrinkle-free and the apparatus main body 100
Can be supplied to the laminated product 104.
It is possible to prevent wrinkles from being generated when fixing the toner.

In this embodiment, the brake B1 interlocking with the lower fixing roller 5b is provided, but the brake B2 interlocking with the film set 103 is eliminated.
Therefore, the above-mentioned predetermined tension may be obtained, and any one may be used as long as such a predetermined tension is obtained.
