Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a laminating apparatus (laminator) for laminating a sheet-shaped recording medium with a laminating film.

[0002]

2. Description of the Related Art Conventionally, "identification card", "consultation ticket",
There is provided a laminating apparatus that seals a sheet-shaped recording medium (hereinafter, referred to as a sheet-shaped medium) on which information such as “photograph” is recorded with a laminating film. This laminating apparatus generally includes a heating (heater) unit for heating the laminate film, and at least one roller pair for pressing and conveying the laminate film and the sheet-shaped medium.

In such a conventional laminating apparatus, one roller forming the above-mentioned roller pair is provided with a plurality of gears arranged between its rotary shaft and the drive shaft of the electric motor as a drive source. The rotating force of the electric motor is transmitted to rotate the electric motor. The other roller forming the roller pair rotates in the opposite direction to the one roller via a drive system such as a gear. The laminated film and the sheet-shaped medium are conveyed by the roller pair having such a configuration.

[0004]

In such a laminating apparatus, the sheet-like medium to be laminated is inserted between the rollers of the pair of rollers while being sandwiched between the pair of laminating films. If it is too thick or if it is inserted at an angle, it will be a situation where the progress will be hindered by the insertion port of the exterior cover for guiding the sheet-shaped medium sandwiched between the laminated films to the nip portion of the roller pair, Sometimes it was jammed between the rollers and jammed. At this time, the sheet-shaped medium is pulled in the front-rear direction in the conveying direction by the pair of rollers and forcedly separated from the rollers.

However, as described above, since the roller pair is structured to interlock with the electric motor through the gear, the roller pair cannot be easily rotated.
Therefore, the sheet-shaped medium or the laminated film may be rubbed on the roller surface to be scratched or damaged.

In consideration of such a situation that the sheet-like medium is sandwiched between the rollers, some laminating apparatuses are configured so that the rotation direction of the rollers can be switched to the opposite direction, or by operating the operation lever. As described above, there is also a structure in which some of a plurality of gears arranged between the drive shaft of the electric motor and the rotation shaft of the roller are disengaged from each other.

However, even if the roller can be rotated in the reverse direction as described above, since the rotating force of the electric motor is not so strong, the sheet-shaped medium is discharged from the nip portion of the roller pair while rotating the electric motor in the reverse direction. Even if you try, if the sheet-shaped medium that is jammed due to being sandwiched is too thick, the load on the motor is too great to rotate the rollers, and you cannot remove the sheet-shaped medium that is jammed. It may not be possible to separate the rollers.

On the other hand, if a part of the plurality of gears arranged between the drive shaft of the electric motor and the rotary shaft of the roller is disengaged from the mesh via the operating lever, the structure of the apparatus becomes complicated and the parts are This leads to an increase in points. Also, if you forget to return the operating lever (that is, forget the return operation to return the device to the normal state) and try to insert the sheet-shaped medium with part of the gear disengaged,
Since it cannot be inserted into the roller pair in a normal state, it is judged as a failure, or the sheet medium does not hit the roller pair that does not rotate and does not progress, so a heating unit etc. arranged upstream of the roller pair in the transport direction. This may damage the sheet medium.

When the sheet-like medium sandwiched by the roller pair cannot be removed by the above-described method, the outer cover of the laminating apparatus is removed to disassemble the parts around the roller pair to form the roller pair 1. The pair of rollers must be separated so that the sheet-shaped medium is separated from the nip portion of the pair of rollers.

It takes a lot of time to remove the sheet medium by such an operation. Further, it is not preferable to remove the outer cover and disassemble the area around the rollers, since it is not preferable in terms of protecting the inside of the apparatus and may cause a failure of the apparatus.

In addition, a part of a plurality of gears arranged between the drive shaft of the electric motor and the rotary shaft of the roller is retracted in a direction substantially orthogonal to the rotary shaft of the roller so that the meshed state is eliminated. Although it is conceivable to remove it, it is necessary to secure a space for retracting the gear in a direction substantially orthogonal to the rotation axis of the roller, which hinders downsizing of the entire device.

The present invention has been made in view of the above problems, and does not hinder the downsizing of the entire apparatus, and it is easy to prevent a sheet-shaped medium jammed by a pair of rollers from jamming the roller surface. It is an object of the present invention to realize a laminating device that can be detached from a device.

[0013]

In order to achieve the above-mentioned object, in the present invention, a sheet-shaped medium and a roller pair for pressing the laminated film heated by the heating means in a state of covering the sheet-shaped medium, A laminating apparatus having a power transmission mechanism for transmitting a driving force from a driving source to at least one roller of a roller pair, wherein at least one of the power transmission members constituting the power transmission mechanism is:
It is slidably arranged substantially parallel to the rotation axis of the roller, and is configured to be movable between a transmission position for transmitting the driving force to another power transmission member and a non-transmission position for not transmitting the driving force. There is.

With such a structure, at least one roller of the roller pair to which the driving force from the driving source is transmitted is moved by moving the movable power transmission member to the non-transmission position, whereby the driving source is driven. It becomes possible to rotate freely without receiving the rotation load from. This makes it possible to easily remove the jammed sheet-like medium without damaging the roller surface of the roller pair.

Further, when removing the jammed sheet-like medium, it is not necessary to remove the exterior cover and disassemble the area around the rollers, which is preferable in terms of protecting the inside of the apparatus. It is also effective in reducing the frequency of occurrence of failures.

By making the slidable direction of the movable power transmission member substantially parallel to the rotation axis of the roller, the size of the device in the direction substantially orthogonal to the rotation axis of the roller can be affected. Therefore, it is possible to contribute to miniaturization of the entire device.

Further, it is desirable that the movable power transmission member has a biasing means for biasing the movable power transmission member from the non-transmission position side toward the transmission position side.

With such a structure, the movable power transmission member is normally urged to the transmission position by the urging means, and the transmission is performed when the jammed sheet-shaped medium is released. It is possible to slide to the non-transmission position by applying a pressing force in the direction from the position side to the non-transmission position side. Then, when the release of the sheet-shaped medium sandwiched between the roller pair is completed and the pressing force in the direction from the transmission position to the non-transmission position is released, the movable power transmission member is moved to the transmission position by the action of the urging means. Return to. That is, various problems (for example, erroneously determined to be a failure, the sheet-shaped medium being damaged, etc.) due to forgetting the return operation for returning to the normal state, which has been a problem in the past, do not occur.

Here, the above-mentioned power transmission mechanism has a plurality of gears, and at least one of the plurality of gears is slidably arranged substantially parallel to the rotation axis of the roller, and is adjacent in the transmission position. It is preferable that the gears are in mesh with other gears and are not in mesh with other gears in the non-transmission position.

In addition to the above, in the above-described power transmission mechanism, the first gear that receives the driving force from the driving source and the first gear that is arranged coaxially with the first gear and that engages with the first gear are received by the first gear. And a second gear for transmitting the driving force to the roller, and a clutch mechanism capable of engaging and disengaging both gears by sliding one of the gears in the axial direction with respect to the other,
One gear may be configured to slide into a transmission position that engages with the other gear and a non-transmission position that disengages from the other gear while meshing with the adjacent gear.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A laminating apparatus L which is a first embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

A laminating apparatus L (an outer cover is not shown) shown in FIG. 1 comprises insertion rollers 1a and 1b for laminating a sheet-like medium (not shown) between a pair of laminating films (not shown). The sheet is inserted from the nip portion of the insertion roller pair S, conveyed, and laminated. The case body 2 is provided with heaters 3a and 3b as heating means for heating the laminate film at a height position corresponding to the nip portion of the insertion roller pair S. Specifically, the heaters 3a and 3b are opposed to each other with their heater surfaces facing each other so as to sandwich the conveyance path of the sheet-shaped medium, and the heater holders 4a and 4b.
The sheet-shaped medium and the laminating film that have been attached to the nip portion of the insertion roller pair S can pass therethrough, and are separated vertically so that a good laminating process can be performed on the sheet-shaped medium by the laminating film. It is arranged so as to be vacant.

On the downstream side of the heaters 3a and 3b in the conveying direction, rollers 5 and 6 having a rotation axis substantially parallel to the rotation axes of the insertion rollers 1a and 1b are rotatably supported. The rollers 5 and 6 are
The roller surfaces are in contact with each other to form a roller pair, and the height position of the nip portion of the roller pair is arranged between the heater 3a and the heater 3b. That is,
The pair of rollers presses the sheet-shaped medium with the laminated film heated by the heater 3a and the heater 3b while covering the sheet-shaped medium.

Incidentally, these insertion rollers 1a and 1b,
Both end portions of the rotation shafts of the rollers 5 and 6 and both end portions of the heaters 3a and 3b in a direction substantially orthogonal to the sheet medium transport direction are provided with a side sheet metal plate 11a provided on the case body 2.
And 11b.

As shown in FIG. 4, roller gears 9 and 10 are attached to one ends 7 and 8 of the rotary shafts of the rollers 5 and 6, respectively, as shown in FIG.

A motor bracket 13 to which an electric motor 12 as a drive source is attached is connected to the side plate metal plate 11a of the case body 2.

The drive shaft 14 of the electric motor 12 passes through a through hole 15 formed in the motor bracket 13 and projects toward the side sheet metal plate 11a. A motor gear 16 is attached to the tip of the protruding drive shaft 14. The motor gear 16 is interlocked with the roller gear 10 attached to the end portion 8 of the rotation shaft of the roller 6 via the idler gear 17 and the idler gear 18.

A swaging shaft 19 for mounting the idler gear 17 and the idler gear 18 on the side plate metal plate 11a.
And a swaging shaft 20 is provided. This caulking shaft 2
Reference numeral 0 is a shaft capable of moving the idler gear 18 in the thrust direction. First, before passing the idler gear 18, the coil spring 21 is passed through the caulking shaft 20, and then the idler gear 18 is attached (see FIG. 5). The idler gear 17 is attached to the caulking shaft 19, and a rib 22 for preventing the idler gear 18 from coming off in the thrust direction is formed in the central portion of the idler gear 17, as shown in FIG. Motor bracket 13
Are attached to the side sheet metal plate 11a to sandwich and fix the idler gear 17 and the idler gear 18 between the motor bracket 13 and the side sheet metal plate 11a.

A through hole 23 is formed near the idler gear 18 of the motor bracket 13. For example, a rod-shaped object such as a screwdriver is passed through the through hole 23,
By applying the pushing force F, the idler gear 18 can be moved in the thrust direction (see FIGS. 5 and 6). The plurality of gears and the like constitute a power transmission mechanism that transmits the driving force from the electric motor 12 to the roller 6. An idler gear 18, which is one of a plurality of gears as a power transmission member constituting the power transmission mechanism, is slidably arranged in a direction substantially parallel to the rotation axes of the rollers 5 and 6.

A power supply circuit section 24 is provided between the side sheet metal plates 11a and 11b described above. The heater 3a, the heater 3b, and the electric motor 12 are connected to the power supply circuit section 24, respectively, and controllable.

Next, the operation for separating the jammed sheet-shaped medium sandwiched between the rollers from between the rollers will be described.

First, the power switch is turned off, and a pushing force F is applied from the outside through a through hole 23 with a rod-shaped member such as a screwdriver from a hole of an exterior cover (not shown) to move the idler gear 18 in the thrust direction (F direction in FIG. 6). Move to. While the pushing force F is applied in this way, the idler gear 18
Is in a disengaged state from the idler gear 17 and the roller gear 10 (that is, in a non-transmission position in which a driving force is not transmitted to another adjacent gear).

Roller 5 and roller 6 forming a pair
Is released from the rotational load due to being interlocked with the electric motor 12, so that it can easily rotate, and pushes or pulls the sheet medium in the jammed state together with the laminate film in the transport direction. As a result, the roller 5 and the roller 6 can also freely rotate following the rotation, so that the sheet-shaped medium in the jammed state can be easily removed.

When the separation of the sheet-like medium is completed in this way, the pushing force F applied from the outside through the through hole 23 is released. When the pushing force F is released, the idler gear 18 is brought into engagement with the idler gear 17 and the roller gear 10 again by the action of the coil spring 21 passing through the caulking shaft 20 (that is, the driving force between another idler gear and the adjacent gear). To the transmission position), and the rollers 5 and 6 can be rotated by receiving the driving force of the electric motor 12 again.

When the idler gear 18 returns to the transmission position, even if the tooth tips of the idler gear 18, the idler gear 17, and the roller gear 10 come into contact with each other and do not mesh with each other, they are attached from the non-transmission position side toward the transmission position side. Since it is biased by the coil spring 21 as a biasing means,
When the drive shaft 14 of the electric motor 12 starts to rotate, the tooth tips of both gears are displaced and mesh with each other.

In the structure near the movable gear in the power transmission mechanism shown in this embodiment, it is not necessary to transmit the torque to the rotating shaft, that is, the driving force received from the adjacent gear is transmitted to the other adjacent gear. Any gear can be applied as long as it has a role of delivering.

As described above, according to the present embodiment, at least one of the pair of rollers to which the driving force from the electric motor is transmitted is moved to the non-transmission position by moving the idler gear as a movable power transmission member. It is possible to rotate freely without receiving the rotational load from the motor. This makes it possible to easily remove the jammed sheet-like medium without damaging the roller surface of the roller pair.

Further, when removing the jammed sheet-like medium, it is not necessary to remove the outer cover and disassemble the area around the rollers, which is preferable in terms of protecting the inside of the apparatus. It is also effective in reducing the frequency of occurrence of failures.

Since the slidable direction of the movable idler gear is set substantially parallel to the rotation axis of the roller, the size of the apparatus in the direction substantially orthogonal to the rotation axis of the roller is not affected, and As a result, it is possible to contribute to downsizing of the entire device.

Further, as described above, the movable idler gear is normally a coil spring because the movable idler gear is biased by the coil spring from the non-transmission position side toward the transmission position side. It is urged to the transmission position by the sheet, and when the jammed sheet-shaped medium is released, it can be slid to the non-transmission position by applying a pressing force in the direction from the transmission position to the non-transmission position. Becomes Then, when the separation of the sheet-shaped medium or the like sandwiched between the roller pair is completed and the pressing force in the direction from the transmission position to the non-transmission position is released, the movable idler gear returns to the transmission position by the action of the coil spring. That is, various problems (for example, erroneously determined to be a failure, the sheet-shaped medium being damaged, etc.) due to forgetting the return operation for returning to the normal state, which has been a problem in the past, do not occur. (Second Embodiment) Next, a laminating apparatus according to a second embodiment of the present invention will be described. The laminating apparatus according to the present embodiment differs from the laminating apparatus according to the first embodiment described above in the configuration of gears near the electric motor. Hereinafter, the same parts as those described above are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 7 is a view of the vicinity of the drive shaft 14 of the electric motor 12 of the laminating apparatus according to the present embodiment as seen from above.

In the laminating apparatus according to this embodiment, instead of the structure of the first embodiment in which the idler gear 18 is slidable in the axial direction of the caulking shaft 20, the motor gear 16 is moved in the axial direction of the drive shaft 14 of the electric motor 12. It is configured to be slidable.

Specifically, a spline S is formed on the inner peripheral surface of a through hole for penetrating the drive shaft 14 of the motor gear 16, and the outer peripheral surface of the drive shaft 14 has a shape S'corresponding to the spline S. It is a formed spline shaft. As a result, the motor gear 16 and the drive shaft 14 are spline-coupled, and the motor gear 16 is slidable in the axial direction of the drive shaft 14 (direction H in FIG. 7). The H direction is substantially parallel to the rotation axes of the rollers 5 and 6. The motor gear 16 is biased in the F ′ direction shown in FIG. 7 by a biasing means (not shown) such as a spring. Normally, the motor gear 16 is biased by this biasing means, and the adjacent idler gear 17 or the like. It is in a position to mesh with.

When the sheet-shaped medium and the laminated film are sandwiched between the rollers and jammed,
Similar to the above-described first embodiment, a pushing force F is applied from the outside through a through hole 23 by a rod-shaped member such as a driver from a hole of an exterior cover (not shown), and the motor gear 16 is axially moved (see FIG.
Move in the middle F direction).

While the pushing force F is applied in this way, the motor gear 16 is disengaged from the idler gear 17 and the like, and is free to rotate around the portion where the shape S'of the drive shaft 14 is not formed as the central axis. Becomes Then, when the work of separating the sheet-shaped medium is completed, the applied pressing force F is released. When the pushing force F is released, the motor gear 16 moves in the F'direction in the drawing by the action of the biasing means (not shown), returns to the position where it meshes with the idler gear 17 and the like again, and meshes (spline-coupled state). ), The rollers 5 and 6 can be rotationally driven again.

In the present embodiment, an example of a normal spline connection is shown, but the present invention is not limited to this. For example, by performing spline connection using a ball spline, the motor gear 16 slides in the axial direction. The operation becomes smooth, and it becomes easy to retreat from the state of meshing with the idler gear 17 or the like that is meshing adjacently and to return to the meshed state.

In this way, if the motor gear 16 is prevented from meshing with other adjacent gears, not only the rollers 5 and 6 but also the insertion rollers 1a and 1b are released from the rotational load of the motor. The separation process of the sheet-shaped medium and the laminated film when a jam occurs becomes easier.

Although the motor gear 16 and the drive shaft 14 of the electric motor 12 are spline-coupled here, one end 7 of the rotary shaft of the roller 5 and the roller gear 9 are similarly connected.
The present invention can be applied to the connection between the roller gear 10 and the one end 8 of the rotary shaft of the roller 6, and the same effects as those described above can be obtained. That is, any gear having a role of transmitting torque to the rotating shaft can be applied. (Third Embodiment) Next, a laminating apparatus according to a third embodiment of the present invention will be described. The laminating apparatus according to the present embodiment is different from the laminating apparatuses according to the above-described embodiments in the configuration of gears near the electric motor. Hereinafter, the same parts as those described above are designated by the same reference numerals, and the description thereof will be omitted.

FIGS. 8A to 8C are views of the vicinity of the drive shaft 14 of the electric motor 12 of the laminating apparatus according to the present embodiment as seen from above.

In the laminating apparatus according to the present embodiment, unlike the structure of each of the above-described embodiments in which the idler gear 18 and the motor gear 16 are slidable in the rotation axis direction, the idler gear 17 described above serves as the second gear in the drive axis direction. The idler gear 17a and the idler gear 17b as the first gear are separable (see FIG. 8), and the inner idler gear 17b is movable in the drive axis direction.

Specifically, the idler gear 17a is rotatably supported by the caulking shaft 19 and is prevented from moving in the thrust direction by a guide (not shown). That is, the idler gear 17 a is always in mesh with the idler gear 18. The caulking shaft 19 here is configured to be freely movable in the thrust direction with respect to the side plate 11a, and the idler gear 17b is fixedly supported by the caulking shaft 19 so that the idler gear 17b and the caulking shaft 19 are thrust. Slides in one direction. In addition, idler gear 1
7b and the caulking shaft 19 are integrally biased by the spring B in the F'direction in FIG.

In this way, the end faces of the idler gear 17a and the idler gear 17b, which are supported by the caulking shaft 19, facing each other are integrally formed with the gears 17a and 17b when the end faces are pressed against each other by the action of the spring B. A meshing clutch K serving as a clutch mechanism is formed so as to rotate in a horizontal direction. That is, the idler gear 17b
Can be engaged with and disengaged from the idler gear 17a by sliding in the direction of the caulking shaft 19. When the dog clutch K is engaged, the driving force received by the idler gear 17b from the electric motor 12 is transmitted to the roller 6.

When the sheet-shaped medium and the laminated film are sandwiched between the rollers and a jam occurs, a pressing force F is applied to the caulking shaft 19 (see FIG. 8A). The caulking shaft 19 which has received the pushing force F moves in the thrust direction together with the idler gear 17b, and first the dog clutch K is in the engaged state (transmission position shown in FIG. 8A).
The idler gear 17b is disengaged from the idler gear 17a and is not meshed (non-transmission position shown in FIG. 8B).

At this time, the idler gear 17b and the motor gear 16 are still in mesh with each other. That is, the idler gear 17b and the motor gear 16, and the idler gear 17a and the idler gear 18 are in mesh with each other,
The rollers 5 and 6 have already been released from the rotational load of the motor.

Then, when the pushing force F is further applied to slide it, the idler gear 17b comes to a position where it is completely disengaged from the meshing state with the adjacent gear as shown in FIG. 8 (c). As a result, the caulking shaft 19 to which the idler gear 17b is fixedly supported is also released from the rotational load of the motor.

In this embodiment, the idler gear 17 is divided into the idler gears 17a and 17b, but the present invention is not limited to this, and the idler gear 18 can be applied.

Of course, the laminating process in each of the above-described embodiments can be performed on either one side or both sides of the sheet-shaped medium.

The laminating apparatus in each of the above-mentioned embodiments includes a polyethylene film, polypropylene film, PVC film, ethylene ethyl acrylate copolymer resin film (EEA film), ethylene vinyl acetate copolymer resin film (EVA film), etc. Any such low melting point thermoplastic film that can be used as a laminating film can be used as the laminating film.

As the sheet-like medium which can be laminated, any sheet having a higher melting point than that of the above-described laminated film can be applied.

A ceramic heater, an electric resistor, a halogen lamp or the like can be applied to the heater as the heating means.

Further, in each of the above-mentioned embodiments, the transmission of the driving force of the motor is transmitted by a plurality of gears, a dog clutch,
Although it is performed using a spline or the like, it is not limited to this. For example, a driving force is transmitted by using a gear mechanism having a plurality of gears and a belt mechanism (or a friction transmission mechanism such as a friction wheel) together. Is also possible. Even in this case, it is needless to say that similar effects can be obtained by applying the configurations of the above-described embodiments.

[0062]

As described above, according to the inventions of the present application, it is possible to easily prevent the size reduction of the entire apparatus from being hindered and to prevent the sheet-shaped medium jammed by the pair of rollers from jamming the roller surface. It is possible to realize a laminating apparatus that can be detached.
