The main body 2 nips the nipped sheets 8 to form a laminated sheet 9. The supply portion 3 supplies the nipped sheets 8 to the main body portion 2. The laminator 1 includes a discharge unit 4 for discharging the laminated sheet 9 from the main body 2.

The laminator 1 includes a control unit 5 that controls the operations of the main body 2 and the supply unit 3. The control unit 5 operates the main body 2 and the supply unit 3 under predetermined conditions. In addition, in the case where the laminator 1 includes the discharge unit 4, the control unit 5 controls the operation of the discharge unit 4.

The laminator 1 includes a power supply unit (not shown) for supplying electric power from a commercial power supply to each unit. The laminator 1 may also include a power switch, a start switch 61, and a notification mechanism 63. The power switch is used to supply power to the device. The start switch 61 is used to start the laminating operation. The notification means 63 is used to notify the user of some information, and in the present embodiment, notifies when the main body 2 needs to be cleaned.

A path in which the nipped sheets 8 are supplied from the supply portion 3 to the main body portion 2, the supplied nipped sheets 8 are nipped by the main body portion 2, and the laminated sheet 9 obtained by the nip is discharged at the discharge portion 4 is referred to as a conveyance path. Further, the to-be-nipped sheet 8 or the laminated sheet 9 is conveyed to the side as the downstream side, and the opposite side thereof is taken as the upstream side. The end of the laminated sheet 9 on the conveyance destination side is referred to as a leading end, and the end on the opposite side is referred to as a trailing end. That is, the front end and the rear end of the laminated sheet 9 correspond to the above-described downstream side and upstream side, respectively.

The sheet to be laminated 8 here is composed of a laminated body 82 as an object to be laminated and a laminated film 81 sandwiching the laminated body 82 from the thickness direction, as shown in fig. 4.

On the opposite surface of the laminated film 81, a thermal adhesive is coated. That is, the main body 2 is laminated by heating and pressing the sheet 8 to be pressed.

Further, the main body 2 is supplied with a supply sheet including at least a sheet to be nipped and a cleaning sheet.

Hereinafter, each part will be explained.

2. Structure of each part

(1) Main body part

The description will be mainly given with reference to fig. 1.

The main body 2 includes, in the case 20: a heating unit that directly or indirectly heats the fed nipped sheets 8; and a pressing unit that presses the heated nipped sheets 8. Here, as an example of the heating means, a heater 21 that heats the pressurizing means may be used, and as an example of the pressurizing means, a roller 22 may be used.

The roller 22 is constituted by a nip roller, for example. Further, the roller 22 functions as a nip roller 22 because it nips the heated sheet to be nipped 8 by pressing. The heater 21 is disposed close to the nip roller 22 and covered with a cover 27.

The main body 2 includes a pressure roller 23 on the downstream side of the nip roller 22 in the housing 20. As an example of the pressure roller 23, a roll can be used. The pressing roller 23 has a function of preventing the laminated sheet 9 after the heating nip from warping. The pressure roller 23 has a cooling function of cooling the laminate sheet 9.

The main body 2 includes a drive mechanism for rotationally driving the nip roller 22 and the pressure roller 23 in the same direction. The drive mechanism herein includes: a drive motor 71 (see fig. 2); and a transmission mechanism that transmits the drive of the drive motor 71 to the nip roller 22 or the pressure roller 23. The drive motor 71 is a main body side drive motor 71 to distinguish from the other drive motors 72.

As the transmission mechanism, for example, a gear, a belt, or the like can be used. The drive motor 71 is controlled by the control unit 5. Here, the rotation of the nip roller 22 when the sheet to be nipped 8 is nipped is regarded as a forward rotation, and the rotation in the opposite direction to the forward rotation is regarded as a reverse rotation. In addition, the positive rotation of the nip roller 22 or the pressure roller 23 is also a direction in which the nipped sheet 8 or the laminated sheet 9 is conveyed from upstream to downstream of the conveyance path.

The main body 2 includes an upper guide 24 that guides the fed sheet 8 to be nipped to the nip roller 22. As an example of the upper guide 24, a guide plate having a conveying path between a pair of plate-shaped portions may be used.

The main body 2 includes a center guide 25 that guides the heated and pressed laminated sheet 9 to the pressure roller 22. As an example of the middle guide 25, a guide plate having a conveying path between a pair of plate-shaped portions may be used.

The main body 2 includes a lower guide 26 that guides the laminate sheet 9 pressed by the pressing roller 23 to the outside of the case 20. As an example of the lower guide 26, a guide plate having a conveying path between a pair of plate-shaped portions may be used.

The laminator 1 includes an upstream sensor 75 for detecting the fed sheet to be laminated 8 on the upstream side of the laminating roller 22 in the inside or outside (in this case, inside) of the housing 20. Further, the signal of the upstream sensor 75 is output to the control unit 5 (see fig. 2).

The laminator 1 includes a downstream sensor 76 for detecting the laminated sheet 9 fed from the pressure roller 23 inside or outside (here, inside) the main body 2. Further, a signal of the downstream side sensor 76 is output to the control unit 5 (see fig. 2).

The upstream sensor 75 and the downstream sensor 76 are, for example, of a transmission type, and the amount of light received differs depending on the presence or absence of the sheet 8 to be nipped and the type of the sheet to be fed.

(2) Supply part

The supply unit 3 includes at least a mounting table 31 and a supply unit. The mounting table 31 mounts one or more supply sheets. As the feeding sheet, there are the nipped sheets 8, the cleaning sheet, and the like, and hereinafter, the nipped sheets 8 and the like. The feeding unit feeds the nipped sheets 8 and the like placed on the table 31 to the main body portion 2. As an example of the supply unit, a roller 32 may be used. The roller 32 is referred to as a feed roller 32 for the sake of name distinction from other rollers. The feed roller 32 is provided to be rotatable in a state of being abutted against the nipped sheet 8 and the like.

The mounting table 31 constitutes a mounting unit 33. The mounting unit 33 here includes a side guide 34 in addition to the mounting table 31.

The mounting table 31 is constituted by a support plate that supports one or more sheets 8 to be bonded from below. The side guides 34 are in contact with side surfaces (side edges in the case of one sheet) parallel to the feeding direction of one or more sheets 8 to be pressed on the table 31. This enables, for example, the sheet to be nipped 8 to be guided straight toward the main body 2.

The side guide plates 34 have a pair of contact surfaces that contact both side surfaces of the sheet 8 to be nipped and the like. The contact surface is formed of, for example, a plate material extending in a direction parallel to the feeding direction and orthogonal to the placement surface. The side guides 34 are provided so that a pair of plate members having contact surfaces on the inner sides thereof can slide in a direction orthogonal to the feeding direction and the front surface of the sheet 8 to be nipped and the like. This can be applied to sheets 8 to be nipped and the like of different sizes.

The supply portion 3 may have an abutment mechanism for abutting the supply roller 32 against the nipped sheet 8 and the like on the table 31. This enables the nipped sheets 8 to be reliably supplied to the main body 2. As an example of the abutting mechanism, a biasing mechanism that biases at least one of the side of the supply roller 32 and the side of the sheet to be nipped 8 or the like in order to bring the sheet to be nipped 8 or the like in a mounted state into abutment with the supply roller 32 may be used. The urging mechanism 35 herein urges the sheet 8 to be nipped or the like from the supply roller 32 side. Further, as the urging mechanism 35, for example, a spring, a spindle, or the like can be used.

The laminator 1 includes a sensor 77 in the supply unit 3. In addition, the sensor 77 is referred to as a mounted sensor 77 for the sake of name distinction from other sensors.

The mounting sensor 77 is provided on the upstream side of the supply roller 32. The placement sensor 77 detects whether or not the sheet to be nipped 8 or the like is placed on the placement table 31. The signal of the placement sensor 77 is output to the control unit 5 (see fig. 2). The placement sensor 77 is, for example, of a transmission type, and the amount of light received varies depending on the presence or absence of the sheet 8 to be nipped, the type of the sheet to be fed, and the like.

The supply unit 3 includes a drive mechanism (not shown) for rotationally driving the supply roller 32. The driving mechanism is different from the driving mechanism on the main body 2 side, and is referred to as a supply-side driving mechanism so as to be distinguishable in name. Here, the supply-side drive mechanism includes: a drive motor 72 (see fig. 2); and a transmission mechanism for transmitting the drive of the drive motor 72 to the feed roller 32. The drive motor 72 is defined as a supply-side drive motor 72 to distinguish the drive motor 72 from the main-body-side drive motor 71. Further, as the transmission mechanism, for example, a gear, a belt, or the like can be used. The supply-side drive motor 72 is controlled by the control unit 5.

The supply roller 32 is in a free state in a state of not being rotationally driven. That is, the stop of the rotational driving of the supply roller 32 means that the driving for rotating the supply roller 32 is stopped, and the supply roller 32 in the driving stopped state can be rotated to become a so-called driven roller.

The rotation of the supply roller 32 is set slower than the rotation of the nip roller 22. The torque of the supply roller 32 is set smaller than the torque of the nip roller 22. Thus, when the nipped sheet 8 and the like are conveyed by the nip roller 22, the nipped sheet 8 and the like are supplied to the main body portion 2 even if the supply roller 32 is in a free state.

The supply unit 3 may be detachably attached to the main body 2, or may be attached to be foldable (openable and closable). This makes it possible to reduce the size of the entire device.

The supply section 3 includes: a jam removing mechanism for removing the sheet 8 to be nipped from the main body 2 when the main body 2 jams the sheet 8 to be nipped and the like.

The clogging removing mechanism includes: when the nip roller 22 and the pressure roller 23 are reversely rotated, another conveyance path different from the conveyance path of the sheet 8 to be nipped and the like is provided. The supply unit 3 includes: for example, a bulging portion 37 that bulges upward as the conveyance path from the supply roller 32 to the nip roller 22 is pushed toward the downstream side; and a take-out port 38 through which the pressed sheet 8 and the like conveyed in the reverse direction to the downstream side of the bulge portion 37 are taken out. The conveying surface of the bulging portion 37 is an inclined surface. When the nip roller 22 or the pressing roller 23 reversely rotates, the nipped sheet 9, the laminated sheet 9, the cleaning sheet, and the like pass through the lower side of the bulging portion 37, and are taken out from the take-out port 38. The path for conveying the nipped sheets 8, the laminated sheet 9, the cleaning sheet, and the like in the reverse rotation is the other conveying path described above.

(3) Discharge part

The discharge unit 4 includes at least a discharge mechanism. The discharge mechanism conveys the laminated sheet 9 or the cleaning sheet (as the laminated sheet 9 or the like) sent out from the main body 2 to the further downstream side. As an example of the discharge mechanism, a roller 41 is used. The roller 41 is a discharge roller 41 for the sake of name distinction from other rollers. The discharge roller 41 is provided to be rotatable in a state of being abutted against the laminated sheet 9 or the like. Further, the discharge roller 41 is provided so as to be in contact with the lower surface of the laminate sheet 9 or the like.

The discharge unit 4 rotationally drives the discharge roller 41 by the drive mechanism of the main body 2. That is, the discharge unit 4 includes a transmission mechanism for transmitting drive from the main body side drive motor 71 to the discharge roller 41. Further, as the transmission mechanism, for example, a gear, a belt, or the like can be used. The driving of the discharge roller 41 is controlled by the control unit 5.

The discharge unit 4 may be detachably attached to the main body 2, or may be attached to be freely folded (freely opened and closed). This makes it possible to reduce the size of the entire device.

(4) Control unit

(4-1) Structure of the drawing

The description will be made with reference to fig. 2.

As shown in fig. 2, the control unit 5 is constituted by a microcomputer provided with a CPU51, a ROM52, a RAM53, and the like. The control unit 5 operates by a power switch operation of the power supply unit. The controller 5 performs various controls and the like while using the RAM53 as an operation area based on programs and data stored in the ROM52 by the CPU 51. The control unit 5 here includes a counter 54 and a timer 55 for performing cleaning management of the nip roller 22, jam processing, and the like.

(4-2) treatment

The control portion 5 performs lamination processing such as feeding of the nipped sheets 8, nipping of the nipped sheets 8, discharging of the laminated sheet 9, and the like. The control section 5 performs a jam corresponding process of excluding the nipped sheet 8 or the laminated sheet 9 in the case where a jam occurs. When cleaning is necessary, the control unit 5 performs a cleaning process related to the cleaning.

In order to perform the above processing, the control unit 5 acquires various signals from, for example, the upstream sensor 75, the downstream sensor 76, the placement sensor 77, and the temperature sensor 78. In addition, a temperature sensor 78 is disposed near the nip roller 22.

(4-2-1) lamination treatment

When the nip condition of the nipped sheet 8 is satisfied, the control portion 5 drives the feeding roller 32 which should feed the nipped sheet 8 and the like. The nip condition of the nipped sheets 8, in other words, is a condition in which the laminated films 81 constituting the nipped sheets 8 can be efficiently nipped with each other without interfering with the preceding fed nipped sheets 8 and the like in the main body portion 2. Even if the feeding sheet is a cleaning sheet, the control section 5 performs control in the same manner as the sheet to be nipped 8.

Examples of the conditions include (a) a temperature Te of the roll surface of the nip roll 22 is equal to or higher than a first temperature Te1 at which welding is possible; (b) one or more sheets to be pressed 8 and the like are placed on the placement table 31; (c) the nipped sheets 8 and the like are not conveyed within the main body portion 2. These conditions can be detected by the placement sensor 77, the upstream sensor 75, the downstream sensor 76, the temperature sensor 78, and the like.

The control section 5 starts driving the nip roller 22, the pressure roller 23, and the discharge roller 41 to rotate positively as receiving a start switch 61 for starting the laminating process from the user. In the present embodiment, the control section 5 drives the nip roller 22, the pressure roller 23, and the discharge roller 41 prior to the driving of the supply roller 32. This can reduce temperature unevenness on the roller surface of the nip roller 22.

(4-2-2) clogging correspondence treatment

When the jam is detected, the control section 5 performs control to take out the nipped sheet 8, the laminated sheet 9, the cleaning sheet, and the like. As an example of the detection of the jam, when the time (the time measured by the timer 55) Ti after the upstream sensor 75 detects the nipped sheet 8 or the like reaches the first time Ti1 and the downstream sensor 76 does not detect the laminated sheet 9, the control section 5 determines that the jam has occurred.

When the jam is detected, the control section 5 drives the nip roller 22, the pressure roller 23, and the discharge roller 41 to rotate reversely for the second time Ti 2.

(4-2-3) cleaning treatment

When the cumulative number of sheets of the nipped sheets 8 nipped by the main body portion 2, that is, the number of stacked sheets LN exceeds the threshold value, the control portion 5 determines the timing to clean the inside of the main body portion 2. The number of laminations LN is obtained by counting the number of sheets of the laminated sheet 9 passing through the main body portion 2 (the nip roller 22) with the counter 54. In addition, the number of laminations LN may also count the number of sheets of the nipped sheet 8 before passing through the nip roller 22.

When determining the timing for cleaning, the control unit 5 causes the notification mechanism 63 to notify a command for cleaning. The notification is displayed as clean. When cleaning is completed in the cleaning display, the control section 5 causes the notification mechanism 6 to terminate the cleaning display.

The notification means 63 is a colored lamp, and is turned on when receiving a signal for a clear display from the control unit 5, and is turned off when receiving a signal for terminating the clear display.

Cleaning is performed by, for example, supplying a cleaning sheet as a supply sheet to the main body 2. Specifically, the dust or the slurry adhering to the nip roller 22 or the pressure roller 23 is removed by heating, nipping, and pressing the cleaning sheet in the main body 2. The cleaning sheet is provided with a mark that can be distinguished from the laminated film, and the control unit 5 determines that cleaning has been performed when the feeding sheet passing through the inside of the main body 2 is a cleaning sheet. The cleaning sheet can be detected by the upstream sensor 75, the downstream sensor 76, and the placement sensor 77.

(4-3) flow chart

The operation of the control unit 5 will be described with reference to the flowchart of fig. 3.

When the power switch is turned ON, the control section 5 starts the program stored in the ROM52 (S1), and when the start switch 61 (shown as "switch" in the figure) is turned ON (ON) (yes in S2), turns ON (ON) the heater 21 to start the temperature rise of the nip roller 22 (S3), and starts the (rotational) driving of the nip roller 22, the pressure roller 23, and the discharge roller 41 (S4).

When the feeding sheet is present on the mounting table 31 (yes in S5), if the temperature Te of the nip roller 22 is higher than Te1 (yes in S6), the control section 5 starts driving of the feeding roller 32 and turns OFF the heater 21 (S7). When the upstream sensor 75 detects the fed sheet fed by the driving of the feed roller 32 (yes at S8), the timer 55 is started (S9).

When the downstream sensor 76 detects the laminated sheet 9 (yes in S10), the control section 5 stops the driving of the supply roller 32 (S11), resets the timer 55 (S12), waits for the laminated sheet 9 not to be detected by the downstream sensor 76 (no in S13), and proceeds to the next process if the laminated sheet 9 is not detected (yes in S13).

Steps S3 to S13 correspond to the above-described lamination process. Also, by detecting the laminated sheet 9 or the like sent out from the pressure roller 23 at step S10, it can be detected that the laminated sheet 9 or the like has passed through the nip roller 22 or the pressure roller 23 by detecting the trailing end of the laminated sheet 9 or the like at step S13.

In step 14, if the supplied sheet is not a cleaning sheet (no in S14), the control section 5 adds "1" to the number of laminations LN indicating the cumulative number of sheets of the nipped sheets 8 nipped by the main body section 2 (S15), and determines whether or not the number of laminations LN is equal to or greater than a threshold (S16).

In step S16, when the number of laminations LN is equal to or greater than the threshold value (yes), the control unit 5 causes the notification mechanism 63 to display a cleaning indication (S17), and when the next feeding sheet is present ON the mounting table 31, that is, when the mounting sensor 77 is ON (yes in S18), the heater 21 is turned ON (ON) (S19), and the process proceeds to step S6. If the number of laminations LN is not equal to or greater than the threshold value (no at S16), the flow proceeds to step S18.

If the placement sensor 77 is not on (no) and the start switch is OFF (OFF) (yes in S20) in step S18, the control section 5 stops driving of the nip roller 22, the pressure roller 23, and the discharge roller 41 (S21), proceeds to step S2, and if the start switch is not OFF (OFF) (no in S20), proceeds to step S18.

In step S10, when the downstream sensor 76 does not detect the laminated sheet 9 or the like (no) and the first time Ti1 elapses from the measurement time Ti of the timer 55 (yes in S22), the control section 5 stops the driving of the supply roller 32 (S23), rotates the nip roller 22, the pressure roller 23, and the discharge roller 44 in reverse for the second time Ti2(S24), resets the timer 55 (S25), and proceeds to step S4. Step S24 corresponds to the congestion correspondence processing.

If the supplied sheet is a clean sheet (yes) in step S14, the control unit 5 terminates the cleaning display (S28) and resets the count of the number of laminations LN (LN is 0) (S29) when the cleaning display is performed (yes in S27), and the process proceeds to step S18.

Further, the control unit 5 terminates the routine when the power switch is OFF (OFF).

3. Is pressed on the sheet material

The description will be given mainly with reference to fig. 4.

As described above, the laminated sheet 8 is formed by overlapping the laminated film 81 and the laminated body 82. In addition, the user sandwiches the prepared laminated body 82 with the laminate film 81 and places it on the supply section 3 of the laminator 1.

(1) Laminated film

The laminated film 81 is configured such that one ends of two film portions 83 are connected to each other. That is, one film of the laminated film 81 is bent at the center in the first direction, and the opposing portion is the film portion 83. In addition, the first direction is a direction in which the nipped sheets 8 are fed to the main body portion 2 by the feeding portion 3. The laminated film 81 here has a rectangular shape which is long in the first direction.

(2) Method of forming

A method of producing the pressed sheet 8 will be described with reference to fig. 4.

Here, the laminated sheet 8 is formed using the auxiliary sheet 85.

The auxiliary sheet 85 is larger than or substantially the same size as the laminated body 82. The auxiliary sheet 85 is provided with a notch portion 85 a.

The production of the pressed sheet 8 as an example is performed by the following steps: (a) the laminate 82 is placed on the auxiliary sheet 85, (b) the auxiliary sheet 85 on which the laminate 82 is placed is disposed between the two film portions 83, and (c) the auxiliary sheet 85 is pulled out leaving the laminate 82.

The arrangement between the film portions 83 of the auxiliary sheet 85 on which the laminated body 82 is placed may be: for example, as shown in fig. 4(a), the film is inserted while sliding between the film portions 83. In this case, the auxiliary sheet 85 preferably has such rigidity that it is not bent by friction with the film portion 83 during sliding.

When the auxiliary sheet 85 is pulled out, as shown in fig. 4(b), the auxiliary sheet 85 can be pulled out by sandwiching the portion of each film portion 83 corresponding to the notch portion 85a of the auxiliary sheet 85 from the outside. The notch portion 85a is formed in a shape that opens in a direction opposite to the direction in which the auxiliary sheet 85 is pulled out. This makes it possible to easily pull out only the auxiliary sheet 85 from between the pair of film portions 83.

The notch portion 85a here is formed at an end portion of the auxiliary sheet 85 on the opposite side of the pull-out direction. The notch portion 85a is formed at an end portion on the opposite side of the pull-out direction of the auxiliary sheet 85 and substantially at the center in the direction (width direction) orthogonal to the pull-out direction. The notch portion 85a has a semicircular shape or a semi-elliptical shape, but may have another shape such as a rectangular shape.

(3) Auxiliary sheet

The material of the auxiliary sheet 85 is not particularly limited. As the material, for example, a metal material, a paper material, a resin material, or the like can be used. The thickness of the auxiliary sheet 85 is not particularly limited, and may be any thickness as long as it can be inserted into a gap between the ends (the portions where the pair of 83 are connected) of the laminate film 81.

The tip end portion (both end portions if the insertion direction is not determined) of the auxiliary sheet 85 may be made smaller in thickness as approaching the tip end. When the auxiliary sheet 85 has a thickness, the auxiliary sheet 85 may be made smaller (shorter) than the laminated body 82, and may be inserted in a state where the auxiliary sheet 85 is slightly (for example, 1[ mm ] to 5[ mm ]) retreated from the distal end of the laminated body 82 in the insertion direction.

< second embodiment >

The laminator 1 of the first embodiment includes the pressure roller 23, and the laminator 101 without the pressure roller will be described in the second embodiment. The biasing mechanism of the second embodiment biases only the supply roller 32 toward the sheet 8 to be nipped. The same reference numerals are used for the same components as those of the first embodiment, and the description thereof will be omitted.

As shown in fig. 5, the laminator 101 includes a main body 102, a supply unit 103, a discharge unit 4, and a control unit 105 (not shown).

The main body 102 includes a heater 21, a nip roller 22, an upper guide 24, a lower guide 26, and a cover 27. The discharge unit 4 includes a discharge roller 41 and discharges the laminated sheet 9 fed out from the lower guide 26.

The supply unit 103 includes a mounting table 131, a supply roller 132, a side guide 34, and a biasing mechanism 135. The biasing mechanism 135 here biases the supply roller 132 toward the mounting table 131 as described above. The feed roller 132 is provided to be movable in the vertical direction, and the feed roller 132 is configured to press the nipped sheets 8 by the own weight of the feed roller 132. The mounting unit 133 is composed of a mounting table 131 and a side guide 34.

The control unit 105 performs substantially the same processing as in the first embodiment, but since the downstream side sensor 76 is located close to the nip roller 22, the first time Ti1, which is a criterion for determining the occurrence of a jam, is changed in step S23 of fig. 3.

The first and second embodiments have been described above, but the present invention is not limited to these embodiments, and for example, the following modifications are possible. Further, the embodiment, the modified example, and the modified example may be combined.

In addition, even if there are examples not described in the embodiment or the modification or design changes without departing from the scope of the invention, the present invention includes the modifications.

< modification example >

1. Structure of the product

(1) The side guides 34 of the supply section 3 are provided with a pair of plate members that are slidable, but may be side guides provided so that, for example, one plate member is fixed and the other plate member is slidable with respect to the one plate member.

(2) The mounting sensor 77 may be any sensor as long as it can detect the feeding sheet (the nipped sheet 8 or the cleaning sheet) mounted on the mounting surface, and may be provided downstream of the feeding roller, for example, when the feeding roller is present at the center of the feeding sheet.

(3) The supply roller 32 is driven by a supply-side drive motor 72 provided separately from the drive mechanism of the nip roller 22 or the pressure roller 23, but a drive motor 71 of the nip roller 22 or the pressure roller 23 may be used. In this case, the feeding roller can be provided with a transmission mechanism for the feeding roller.

The supply roller 32, the nip roller 22, the pressure roller 23, and the discharge roller 41 can be rotated by one driving unit. In this case, since the supply roller 32 is decelerated in rotation speed with respect to the nip roller 22, a circuit configuration or control for reducing torque becomes complicated, the number of parts increases, the kind of motor is changed, and therefore, it is possible to design more simply by providing the driving unit separately.

(4) The ejection port 38 of the jam removal mechanism is provided in the conveyance path in the supply unit 3, but the ejection port may be provided, for example, at a connection portion between the main body and the supply unit, or may be provided in the main body. Further, the ejection port is located downstream of the mounting table, and the structure of the supply unit can be simplified. The ejection port may be located in the main body together with the swelling portion.

(5) The discharge roller 41 is provided so as to abut on the lower surface of the laminated sheet 9, but may be, for example, an ejection roller that abuts on the upper surface of the laminated sheet 9.

(6) The heater 21 of the main body 2 heats the nip roller 22, but may be a heater that directly heats the sheet to be nipped. The nip roller 22 is heated by the external heater 21, but the nip roller may have a built-in heater, or the roller may have a built-in heater and be heated from the outside.

(7) The placement sensor 77, the upstream sensor 75, and the downstream sensor 76 are of a transmissive type in which the light emitting section and the light receiving section are disposed facing each other, but for example, a reflective sensor or another sensor in which the light emitting section and the light receiving section are located on the same side may be used.

(8) The laminator 1 is provided with the supply unit 3 so as to be openable and closable or detachable, but the supply unit may be fixed to the main body or may be incorporated in the main body. As an example of assembly, there is a case in which the supply unit is provided in the body.

(9) The laminator 1 includes the discharge portion 4, but the laminator may not include the discharge portion, and the discharge portion may be provided in a state of being incorporated in the main body. As an example of assembly, there is a case in which the discharge portion is provided in the body portion.

(10) The biasing mechanism 35 biases the supply roller 32 side toward the sheet 8 to be nipped or the like, but the biasing mechanism may bias the supply roller 32 side from the mounting table 31 side, or may bias both the direction from the mounting table 31 side toward the supply roller 32 side and the direction from the supply roller 32 side toward the mounting table 31 side, for example.

(11) The notch portion 85a of the auxiliary sheet 85 is formed at the substantially center of the end portion side on the opposite side to the drawing direction, but may have a notch portion at the end in the width direction of the end portion side. In the case where the notch portion is present at the end, the drawing direction can be set to two directions, i.e., a direction opposite to the feeding direction and a direction orthogonal to the feeding direction. Further, the notch portion may be provided in a plurality of places instead of one place.

(12) The auxiliary sheet may be a dedicated sheet, may be a laminated body, or may be sized in accordance with a general paper size. In this case, for each of the sizes of A3, a4, a5, etc., which are commonly used, an auxiliary sheet slightly larger than or substantially the same size as the size thereof can also be manufactured.

(13) Cleaning sheet

The cleaning sheet is not particularly limited, and for example, thick paper can be used. This strongly presses the roller against the thick paper, and the slurry or the like on the roller surface easily adheres to the thick paper. Further, as the cleaning sheet, cloth, a resin plate, or the like can be used.

2. Control of

(1) Conditions for feed roller drive

(1-1) in the first embodiment, an example of the conditions for driving the supply roller 32 is described, but the supply roller 32 may be driven under other conditions.

For example, the driving of the supply roller may be started when the control section receives an operation of a start switch from a user.

For example, a feed switch may be additionally provided, and the feed roller may be driven when receiving a feed switch operation by a user.

For example, the supply roller may be driven even when the nipped sheet 8 or the like is not placed on the placing table 31. However, the power consumption of the apparatus can be further controlled on condition that the sheet to be nipped or the like is placed.

(1-2) in the first embodiment, the supply roller 32 is driven in the case where the temperature Te of the nip roller 22 is higher than Te1, but the supply roller may be preliminarily driven regardless of the temperature of the nip roller 22, for example, in the case where the sheet 8 to be nipped is directly heated or in the case where the heating of the nip roller does not require a preparation time.

(2) Feed roller drive stop

In the first embodiment, when the downstream side sensor 76 detects the laminated sheet 9, the rotational driving of the feed roller 32 is stopped (step S11 in fig. 3). However, the rotational driving may be stopped under other conditions.

(2-1) as an example of the other condition, the rotation driving may be stopped after the third time Ti3 elapses from the time Ti measured by the timer 55 after the upstream sensor 75 detects the nipped sheet 8. In this case, as shown in fig. 6, after the timer 55 is started in step S9 of fig. 3, when the measurement time Ti of the timer 55 is equal to or longer than the time Ti3 (yes in S91), the control unit stops the driving of the supply roller 32 (S92) and proceeds to step S10.

The time Ti3 corresponds to an example of the "predetermined time" in the present invention. The time Ti3 is equivalent to the time after the upstream side sensor 75 detects the nipped sheet 8 until the nip roller 22 is reached. This stops the supply roller 32 at an early stage, thereby achieving energy saving. In addition, the time Ti3 is obtained from calculation, experiment, or the like of the rotation speed of the supply roller, the distance to the sensor and the nip roller, or the like. In step S10, when the downstream side sensor 76 detects the laminated sheet 9 (yes), the jam does not occur, the timer 55 is reset (S12), and the process proceeds to step S13 in fig. 4. In step S10 of fig. 6, when the downstream side sensor 76 cannot detect the laminated sheet 9 (no), the routine proceeds to step S22 of fig. 3, and waits until the first time Ti1 elapses from the measurement time Ti of the timer 55, after the downstream side sensor 76 detects the laminated sheet 9, the routine proceeds to step S24.

(2-2) as an example of the other condition, it may be that even if the driving of the feeding roller is stopped, the feeding roller is rotated by inertia, and in a case where the nipped sheet 8 or the like reaches the nip roller 22, the upstream side sensor 75 stops the rotational driving after detecting the nipped sheet 8. In fig. 3, step S11 may be performed between step S8 and step S10.

(3) Continuous drive of supply roller

In the first embodiment, the driving of the feed roller 32 is started or stopped. However, the driving of the feed roller may also be continuously driven in the same manner as the nip roller. In the continuous driving, for example, the rotation of the supply roller 32 is made slower than the nip roller 22 and the like and the torque of the supply roller 32 is made smaller than the nip roller 22 and the like, and after the fed nipped sheet 8 and the like passes through the nip roller 22, the fed nipped sheet 8 and the like may reach the nip roller 22. This can be done, for example, by adjusting the spacing of the supply roll 32 from the nip roll 22 or the rotational speed of the supply roll 32 and the nip roll 22.

3. Occlusion correspondence process

(1) Occlusion detection

In the first embodiment, even if the laminated sheet 9 is not conveyed beyond the time for normally conveying the laminated sheet 9, it is considered that the jam has occurred, but the occurrence of the jam may be detected by another method.

As another method, for example, a sensor may be provided above the conveyance path of the nipped sheet 8, the laminated sheet 9, the cleaning sheet, or the like on the upstream side of each of the nip roller and the pressure roller, and the sensor may detect when the nipped sheet 8, the laminated sheet 9, the cleaning sheet, or the like is bent.

(2) Treatment of blockages

In the first embodiment, when the jam is detected, the nip roller 22, the pressure roller 23, and the discharge roller 41 are driven in reverse rotation, but the control unit may deal with this by another method.

(2-1) for example, the position where the jam occurs may be detected, and only the roller located on the upstream side of the position where the jam occurs may be driven in a counter-rotating manner. Any configuration may be employed as long as the rollers are driven and controlled independently.

(2-2) for example, the rotation of the nip roller 22, the pressure roller 23, and the discharge roller 41 may be stopped, and the operator may manually remove the jammed sheet 8 or the laminated sheet 9, or the operator may operate a switch for reverse rotation to remove the jammed sheet 8 or the laminated sheet 9. In addition, the heater 21 may be turned OFF (OFF) according to circumstances.

4. Supply roller and press roller

In the first embodiment, the rotation of the supply roller 32 is set slower than the rotation of the nip roller 22, and the torque of the supply roller 2 is set smaller than the torque of the nip roller 22. However, the speed and torque of each roller may be controlled by the control unit.

5. Cleaning process

(1) About notification mechanisms, etc

In the first embodiment, a colored lamp is used as the notification means 63 for displaying a cleaning state. However, the user may be notified of the command to clean by other means. Examples of the other notification include a sound emitting means for emitting a sound such as a buzzer, and a display means for displaying a character such as "clear".

Further, when the cleaning timing is set, the control unit may maintain the state in which the rotational driving of the supply roller 32 is stopped. This enables the user to recognize the timing of cleaning.

As another notification, two or more types of the lamp, the sound generation mechanism, the display mechanism, the rotation stop, and the like may be combined.

(2) Cleaning of

(2-1) the cleaning process of the first embodiment is performed by supplying a cleaning sheet to the main body portion 2, the cleaning sheet passing through the main body portion 2 under the same condition as the condition in which the nipped sheet 8 passes through the main body portion 2 (hereinafter also simply referred to as "passing condition").

However, the control portion may also make the passing condition of the cleaning sheet different from the passing condition of the nipped sheet 8. For example, when a cleaning sheet is detected or input, the temperature of the nip roller may be raised, the rotational speed of the nip roller may be slowed, or the cleaning sheet may be reciprocated once or multiple times on the nip roller.

The reciprocating of the stitching roller can be performed, for example, as follows: the rotation direction is changed by the upstream sensor 75 or the downstream sensor 76 detecting the cleaning sheet. For example, the control unit may repeat control of rotating the main body side drive motor 71 in the reverse direction when the upstream side sensor 75 detects the upstream side end of the cleaning sheet in the conveying direction, and rotating the main body side drive motor 71 in the forward direction when the downstream side sensor 76 detects the downstream side end of the cleaning sheet in the conveying direction, at least once. The reverse rotation or the forward rotation may be changed after a predetermined time has elapsed since the end of the cleaning sheet was detected.

The conditions for passing the cleaning sheet can be changed by storing data such as temperature and speed for cleaning in the ROM52, and changing and processing these conditions in the case of the cleaning sheet.

(2-2) the cleaning process of the first embodiment is to convey a cleaning sheet on the same conveyance path as the conveyance path on which the nipped sheet 8 is conveyed.

However, the control portion may also make the conveying path of the cleaning sheet different from the conveying path of the nipped sheet 8. For example, when a cleaning sheet is detected or input, the nip roller 22 may be rotated forward and then rotated backward to take out the cleaning sheet from the reverse conveyance path (the take-out port 38) used in the jam processing.

The change of the conveying path of the cleaning sheet may be performed by performing the same process as the jam correspondence process (step S24 in fig. 3).

(2-3) the cleaning process of the first embodiment is performed without stopping the apparatus, but for example, when a cleaning display is performed, the rotation of the nip roller 22 or the like may be stopped, and after receiving an operation signal from a cleaning switch of a user, the nip roller 22 may be rotated to perform the cleaning process.

In addition, when the cleaning display is performed, the user may operate the cleaning switch after placing the cleaning sheet on the placing table without stopping the rotation of the nip roller 22 and the like.

(2-4) flow charts

As described in (2-1) or (2-2), a flowchart of the control unit in the case where the cleaning process is different from the laminating process will be described with reference to fig. 7. In fig. 7, the clogging process is not described, but the clogging process may be performed by performing step S23 and step S24 described in fig. 3.

When a power switch is turned ON, the control unit starts a program (S101) and starts the ON (ON) of the switch (YES in S102), and determines whether or not a sheet is supplied ON the mounting table (S103).

In step S103, when there is a feed sheet (yes), it is determined whether the feed sheet is the nipped sheet 8 or the cleaning sheet. In addition, the placement sensor 77 may be used for determination.

In the case where the fed sheet is the nipped sheet 8, the lamination process is performed (S105), and the number of laminations LN is increased by "1" (S106). When the number of laminations LN is equal to or greater than the threshold value (yes in 107), a cleaning display is performed (S108).

Thereafter, when the sheet is fed on the table (yes in S109), the process proceeds to step S104, and when the sheet is not fed (no in S109), the process proceeds to step S110.

In step S110, when the switch is OFF (OFF) (no), the process proceeds to step S103.

If the feeding sheet is a cleaning sheet in step S104, the cleaning process is performed (S111), and if the cleaning display is in progress (yes in S112), the cleaning display is terminated (S113), the number of laminations LN is reset (S114), and the process proceeds to step S109. In addition, when the display is not in the cleaning display (no) in step S112, the process proceeds to step S114.

(3) Detection of cleaning sheets

The detection of the cleaning sheet may be performed by any one of the placement sensor 77, the upstream sensor 75, and the downstream sensor 76, or may be performed by, for example, providing a cleaning switch and detecting the presence or absence of operation of the cleaning switch when the user uses the cleaning sheet.

(4) Timing of cleaning

The number of laminations LN is the number of sheets of the nipped sheets 8 or the laminated sheets 9 counted, but may be, for example, a feeding sheet fed to the nip roller 22 or a sheet passing through the nip roller 22 counted. In this case, the cleaning sheets are also counted, but the problem is not serious because the counter 54 is reset in accordance with the passage of the cleaning sheets.

(5) Notification content

When the cleaning timing is reached, the control section 5 turns on a colored lamp as the notification means 63. However, it may also be displayed in the form of an early cleaning.

Further, when a new switch is turned ON (ON), for example, when cleaning is required in the previous use and the switch is turned OFF (OFF) in this state, a display may be displayed to urge cleaning to be performed first. When the cleaning treatment is performed before the laminating treatment, the dust and the like can be well removed.

6. Control unit

The control unit automatically starts the execution of the program when the power switch is turned on, but may start the program when power is supplied to the laminator, for example, or may start the execution from step S3 in fig. 3 when power is supplied. In this case, the connection and disconnection of the commercial power supply to the outlet function as the start switch 61 of the first embodiment.
