[Technical Field]

[0001] The present invention relates to a conveying device for conveying a member. [Background technology]

[0002] Patent Document 1 describes a tape printing device that can perform high-precision, fixed-length printing by correcting the printing cycle for driving the thermal head to print each time the amount of rotation of the DC motor reaches a predetermined number, even if the rotation speed of the DC motor fluctuates due to factors such as an increase in the winding resistance value caused by heat generation in the DC motor during continuous operation.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-111863 Summary of the Invention [Problem to be solved by the invention]

[0004] In the printing device described in Patent Document 1, stopping the motor that drives the transport mechanism stops the tape transport and removes the load from the motor. However, in devices that have a mechanism that applies tension to the tape in addition to the transport mechanism, tension continues to be applied to the tape even when the motor that drives the transport mechanism is stopped, which can cause the tape to move to an unintended position.

[0005] The present invention has been made in consideration of the above circumstances, and its purpose is to provide a means for easily restarting an apparatus after the drive unit that drives the conveying mechanism has stopped due to heat generation, when the apparatus is equipped with a mechanism that applies tension to a member other than the conveying mechanism. [Means for solving the problem]

The tension applying unit applies tension to the member between the conveying mechanism and the tension applying unit. When the control unit determines that the temperature of the drive unit has reached a first value, the control unit performs reverse conveyance control to drive the drive unit so that the conveying mechanism conveys the member in a direction opposite to the conveying direction to a position where the member is not gripped by the conveying mechanism.

DETAILED DESCRIPTION OF THE INVENTION

[0037] The following describes a laminating device 1 according to an embodiment of the present invention. The embodiment described below is merely an example of the present invention, and it goes without saying that the embodiment of the present invention can be modified as appropriate without departing from the spirit and scope of the present invention. In the following description, the direction of travel is expressed as the direction from the start point of an arrow to the end point, and the direction of travel on the line connecting the start point and end point of an arrow. Furthermore, the up-down direction 7 is defined based on the state in which the laminating device 1 is installed and ready for use (the state shown in FIG. 1(A)), the front-back direction 8 is defined with the surface on which the operation unit 12 and display unit 13 are provided as the front, and the left-right direction 9 is defined when viewing the laminating device 1 from the front. The up-down direction 7, the front-back direction 8, and the left-right direction 9 are perpendicular to one another.

[0038] The laminating devices 1 according to the first to fifth embodiments have roughly the same configuration and perform roughly the same operations. However, the laminating devices 1 according to the first to fifth embodiments perform different operations when the temperature of the motor reaches a predetermined value. The laminating device 1 is an example of a conveying device.

[0039] [Overview of Laminating Device 1] As shown in Fig. 1(A), the laminating device 1 according to the first to fifth embodiments has a rectangular parallelepiped housing 11. An operation unit 12 and a display unit 13 are located on the front of the housing 11. On the front of the housing 11, below the operation unit 12 and the display unit 13, an outlet 14 is located. The laminating device 1 bonds two types of members together to create a finished laminated product 100.

[0040] A tape-shaped first member 101 and a second member 102 are supplied to the laminating apparatus 1. As shown in FIG. 2, the first member 101 is wound around a cylindrical core material 113 to form a first roll 111. The second member 102 is wound around a cylindrical core material 114 to form a second roll 112. The first roll 111 and the second roll 112 are attached to a first holder 21 and a second holder 22 of the laminating apparatus 1, respectively.

[0041] The first member 101 is, for example, a transparent film. As shown in FIG. 1(B), the second member 102 is a member having an adhesive layer on at least one surface. The second member 102 is, for example, a backing sheet having a first adhesive layer 103 on one surface of a tape layer 104 (the surface facing the first member 101 in the finished laminate 100) and a second adhesive layer 105 on the other surface of the tape layer 104. A release sheet 106 is provided on the opposite side of the tape layer 104 with the second adhesive layer 105 sandwiched therebetween.

[0042] The first member 101 and the second member 102 may be made of any material. The second member 102 may be made of, for example, a resin material such as PET or PVC (polyvinyl chloride), synthetic paper such as Yupo paper (registered trademark), or a metal material. The second member 102 may be transparent or opaque. The first member 101 and the second member 102 may have an adhesive layer on one surface, an adhesive layer on the other surface, an adhesive layer on both surfaces, or neither surface. When a material without an adhesive layer is used, the first member 101 and the second member 102 may be bonded together after an adhesive is applied thereto, or may be bonded together by heat welding, pressure bonding, or the like.

[0043] 2, the recording surface 107 is the surface of the first member 101 on which an image is recorded. The back surface 108 is the surface of the first member 101 opposite the recording surface 107. The bonding surface 109 is the surface of the second member 102 that has the first adhesive layer 103.

[0044] The laminating device 1 bonds the first member 101 and the second member 102 by bringing the recording surface 107 of the first member 101 into close contact with the bonding surface 109 of the second member 102. The laminating device 1 cuts the bonded members into a predetermined size. This creates a finished laminated product 100 shown in FIG. 1(B). The created finished laminated product 100 is discharged from the discharge port 14.

[0045] As shown in FIG. 2, the laminating apparatus 1 includes a first holder 21, a second holder 22, a recording unit 30, first to third conveying rollers 41 to 43, an intermediate roller 44, a laminating roller 50, a tension generating unit 60, a slack sensor 63, a media sensor 64, a first cutting unit 68, and a second cutting unit 69 within a housing 11. Additionally, the laminating apparatus 1 includes a control unit 90 and various motors within the housing 11 (see FIG. 3). Guide members (not shown) that support a first member 101 are provided at necessary positions within the housing 11. This forms a conveying path 15 that runs from the first holder 21 to the second cutting unit 69 via the recording unit 30, the first cutting unit 68, and the laminating roller 50. The first member 101 is conveyed on the conveying path 15 in a conveying direction 16 from the first holder 21 toward the second cutting unit 69.

[0046] [First holder 21 and second holder 22] The first holder 21 and the second holder 22 are members that can rotate around an axis extending in the left-right direction 9. The thickness of the first holder 21 is equal to the inner diameter of the core material 113 of the first roll 111. The thickness of the second holder 22 is equal to the inner diameter of the core material 114 of the second roll 112. The first holder 21 and the second holder 22 are fixed to the housing 11 or to a member fixed to the housing 11.

[0047] The first holder 21 and the second holder 22 are located at positions spaced apart from each other within the housing 11. In the configuration shown in Fig. 2, the first holder 21 is located near the center of the housing 11 in the up-down direction 7 and at the rear of the housing 11 in the front-rear direction 8. The second holder 22 is located at the top of the housing 11 in the up-down direction 7 and forward of the center of the housing 11 in the front-rear direction 8. The positions of the first holder 21 and the second holder 22 within the housing 11 are arbitrary.

[0048] Before the laminating apparatus 1 operates, a first roll 111 is attached to the first holder 21, and a second roll 112 is attached to the second holder 22. The first holder 21 rotatably supports the first roll 111. The second holder 22 rotatably supports the second roll 112. The first member 101 is pulled out from the first roll 111 supported by the first holder 21. The second member 102 is pulled out from the second roll 112 supported by the second holder 22.

[0049] A force acting in a direction to wind up the first member 101 is applied to the first holder 21 from the second motor 82 (see FIG. 3). A force acting in a direction to wind up the second member 102 is applied to the second holder 22 from the third motor 83 (see FIG. 3).

[0050] [Recording Section 30] The recording unit 30 is located downstream of the first transport roller 41 in the transport direction 16 and records an image on the first member 101. The recording unit 30 is located above the transport path 15 in the up-down direction 7 and between the first transport roller 41 and the first cutting unit 68 in the front-rear direction 8. The recording unit 30 includes a carriage 31 and a recording head 32. Inside the housing 11, there are located two guide rails (not shown) that extend in the left-right direction 9 and have both ends fixed to the housing 11 or to members fixed to the housing 11. The carriage 31 is placed on the two guide rails. The carriage 31 receives driving force from a CR motor 84 (see FIG. 3) and moves in the left-right direction 9.

[0051] The recording head 32 is mounted on a carriage 31. A plurality of nozzles 33 are formed on the underside of the recording head 32. As the carriage 31 moves, the recording head 32 moves in the left-right direction 9. A platen 34 is located below the movement range of the carriage 31. While moving in the left-right direction 9, the recording head 32 ejects ink downward from the nozzles 33 based on image data supplied from a control unit 90. As a result, an image based on the image data is recorded on a recording surface 107 of the first member 101 transported on the platen 34.

[0052] [First to third conveying rollers 41 to 43 and intermediate roller 44] The first to third conveyance rollers 41 to 43 and the intermediate roller 44 convey the first member 101 in the conveyance direction 16. The first to third conveyance rollers 41 to 43 and the intermediate roller 44 are positioned between the first roll 111 and the laminating roller 50. The intermediate roller 44 and the first conveyance roller 41 are positioned between the first roll 111 and the recording unit 30 in the front-to-rear direction 8. The second conveyance roller 42 and the third conveyance roller 43 are positioned between the recording unit 30 and the laminating roller 50 in the front-to-rear direction 8. The first conveyance roller 41 is positioned in front of the intermediate roller 44 in the front-to-rear direction 8. The third conveyance roller 43 is positioned in front of the second conveyance roller 42 in the front-to-rear direction 8. The intermediate roller 44 is positioned upstream of the first conveyance roller 41 in the conveyance direction 16, and is positioned between the first roll 111 and the first conveyance roller 41 in the conveyance direction 16.

[0053] The first conveying rollers 41 include a first roller 411 and a second roller 412. The first roller 411 is located directly above the second roller 412. The first member 101 passes between the first roller 411 and the second roller 412. At this time, the first roller 411 abuts against the recording surface 107 of the first member 101, and the second roller 412 abuts against the back surface 108 of the first member 101. As a result, the first conveying rollers 41 grip the first member 101.

[0054] The second roller 412 receives a driving force from the first motor 81 (see FIG. 3 ) and rotates about an axis extending in the left-right direction 9. Accordingly, the first roller 411 also rotates about an axis extending in the left-right direction 9. At this time, a force in a direction pulling the first member 101 from the first roll 111 acts on the first member 101. Furthermore, the second roller 412 receives a driving force in the opposite direction from the first motor 81 and rotates in the reverse direction, and accordingly the first roller 411 also rotates in the reverse direction. At this time, a force in a direction moving the first member 101 closer to the first roll 111 acts on the first member 101.

[0055] The second conveyor rollers 42 include a third roller 421 and a fourth roller 422. The third conveyor rollers 43 include a fifth roller 431 and a sixth roller 432. The configurations and functions of the second conveyor rollers 42 and the third conveyor rollers 43 are the same as those of the first conveyor rollers 41, and therefore will not be described here.

[0056] The intermediate rollers 44 include a seventh roller 441 and an eighth roller 442. The eighth roller 442 receives a driving force from the second motor 82 and rotates about an axis extending in the left-right direction 9. Accordingly, the seventh roller 441 also rotates about an axis extending in the left-right direction 9. At this time, a force in a direction pulling the first member 101 from the first roll 111 acts on the first member 101. Furthermore, the eighth roller 442 receives a driving force in the opposite direction from the second motor 82 and rotates in the reverse direction, and accordingly the seventh roller 441 also rotates in the reverse direction. At this time, a force in a direction moving the first member 101 closer to the first roll 111 acts on the first member 101.

[0057] Here, of the two rollers included in the first to third conveyor rollers 41 to 43 and the intermediate roller 44, the lower roller receives driving force from a motor. Alternatively, the upper roller may receive driving force from a motor, or both the upper and lower rollers may receive driving force from a motor. Also, it is not necessary for all of the first to third conveyor rollers 41 to 43 to receive driving force from the first motor 81. The first to third conveyor rollers 41 to 43 and the intermediate roller 44 may each receive driving force independently from a different motor, or may receive driving force from a motor that drives a motor other than the motor that drives the first to third conveyor rollers 41 to 43 and the intermediate roller 44.

[0058] [Laminating Roller 50] The laminating roller 50 is located downstream of the first conveying roller 41, the recording unit 30, and the first cutting unit 68 in the conveying direction 16, and conveys the first member 101 while laminating the first member 101 and the second member 102 together. The laminating roller 50 is located between the first cutting unit 68 and the second cutting unit 69 in the front-rear direction 8. The laminating roller 50 includes a first laminating roller 51 and a second laminating roller 52. The first laminating roller 51 is located directly above the second laminating roller 52. The first laminating roller 51 and the second laminating roller 52 grip the first member 101 and the second member 102 with a predetermined force. As a result, the first member 101 and the second member 102 are laminated together to form a finished laminate 100.

[0059] The second member 102 pulled out from the second roll 112 enters between the first laminating roller 51 and the second laminating roller 52. At this time, the laminating surface 109 of the second member 102 faces downward. The first member 101 that has passed through the recording unit 30 and the first cutting unit 68 enters below the second member 102 between the first laminating roller 51 and the second laminating roller 52. At this time, the recording surface 107 of the first member 101 faces upward.

[0060] The second laminating roller 52 receives a driving force from the third motor 83 and rotates about an axis extending in the left-right direction 9. Accordingly, the first laminating roller 51 also rotates about an axis extending in the left-right direction 9. The first laminating roller 51 and the second laminating roller 52 bond the first member 101 and the second member 102 together by bringing the recording surface 107 of the first member 101 and the laminating surface 109 of the second member 102 into close contact with each other. Note that the first laminating roller 51 may receive a driving force from the third motor 83, or both the first laminating roller 51 and the second laminating roller 52 may receive a driving force from the third motor 83.

[0061] Furthermore, the laminating roller 50 does not necessarily have to bond the first member 101 and the second member 102 together. For example, if the laminating apparatus 1 has a section downstream of the laminating roller 50 where thermal welding or pressure bonding is performed, the laminating roller 50 is a roller pair that is placed before that section and that overlaps the first member 101 and the second member 102.

[0062] [Tension generating unit 60 and slack sensor 63] The tension generating unit 60 is located upstream of the first conveyor roller 41 in the conveying direction 16, and applies tension to the first member 101 between the first conveyor roller 41 and the tension generating unit 60. The tension generating unit 60 is also located between the first conveyor roller 41 and the intermediate roller 44 in the conveying direction 16, and applies tension to the first member 101 held between the first conveyor roller 41 and the intermediate roller 44. The intermediate roller 44 is located upstream of the tension generating unit 60 in the conveying direction 16.

[0063] The tension generating unit 60 is located below the conveying path 15 in the up-down direction 7 and between the first conveying roller 41 and the intermediate roller 44 in the front-rear direction 8. The tension generating unit 60 includes a contact member 61 and a spring 62 that expands and contracts in the up-down direction 7. The lower end of the spring 62 is fixed within the housing 11, and the upper end of the spring 62 is connected to the lower end of the contact member 61. The upper end of the contact member 61 can contact the back surface 108 of the first member 101 between the first conveying roller 41 and the intermediate roller 44. A tension corresponding to the restoring force of the spring 62 is applied to the first member 101 that contacts the contact member 61. The tension generating unit 60 generates a predetermined tension in the first member 101 between the first conveying roller 41 and the intermediate roller 44.

[0064] The contact member 61 moves in the up-down direction 7 in accordance with the tension of the first member 101 between the first conveyor roller 41 and the intermediate roller 44. When the tension of the first member 101 is large, the contact member 61 is positioned relatively lower against the restoring force of the spring 62, and when the tension of the first member 101 is small, the contact member 61 is positioned relatively higher due to the restoring force of the spring 62. Note that the restoring force of the spring 62 is weaker than the force applied from the first motor 81 to the first conveyor roller 41 and the force applied from the second motor 82 to the first roll 111.

[0065] In this way, the tension generating unit 60 is configured not to apply tension to the first member 101 when the length of the first member 101 between the first conveying roller 41 and the intermediate roller 44 is equal to or greater than a predetermined length, and to apply tension to the first member 101 when the length is less than the predetermined length. Note that the contact member 61 may be configured to be able to come into contact with the surface (recording surface 107) of the first member 101.

[0066] The slack sensor 63 is located near the lower end of the contact member 61 in the up-down direction 7. The slack sensor 63 includes a light-emitting element (not shown) that emits light toward the side surface of the contact member 61 and a light-receiving element (not shown) that receives light reflected by the side surface of the contact member 61. When the tension of the first member 101 is large and the slack of the first member 101 is small, the contact member 61 is located below the reference position. At this time, the light-receiving element of the slack sensor 63 receives light reflected by the side surface of the contact member 61, and the amount of light detected by the light-receiving element is greater than the threshold value. On the other hand, when the tension of the first member 101 is small and the slack of the first member 101 is large, the contact member 61 is located above the reference position. At this time, the light-receiving element of the slack sensor 63 does not receive light reflected by the side surface of the contact member 61, and the amount of light detected by the light-receiving element is less than the threshold value.

[0067] The contact member 61 is movable between a first position where tension is applied to the first member 101 between the first conveyor roller 41 and the intermediate roller 44, and a second position where tension is not applied to the first member 101 between the first conveyor roller 41 and the intermediate roller 44. The slack sensor 63 detects whether the contact member 61 is located at the first position.

[0068] [Media Sensor 64] The media sensor 64 is located downstream of the first conveyance roller 41 in the conveyance direction 16 and detects the first member 101. The media sensor 64 is mounted on the carriage 31 and is provided on the nozzle surface of the recording head 32. The media sensor 64 includes a light-emitting element (not shown) that emits light toward the recording surface 107 of the first member 101 conveyed on the conveyance path 15, and a light-receiving element (not shown) that receives light reflected by the recording surface 107 of the first member 101. When the first member 101 is located below the media sensor 64, the light-receiving element of the media sensor 64 receives light reflected by the recording surface 107 of the first member 101, and the amount of light detected by the light-receiving element is greater than the threshold. On the other hand, when the first member 101 is not located below the media sensor 64, the light-receiving element of the media sensor 64 does not receive light reflected by the recording surface 107 of the first member 101, and the amount of light detected by the light-receiving element is less than the threshold.

[0069] [First cut portion 68 and second cut portion 69] The first cutting unit 68 is located between the first conveyance roller 41 and the laminating roller 50 in the conveying direction 16, and cuts the first member 101. The first cutting unit 68 is located downstream of the recording unit 30 in the conveying direction 16. The first cutting unit 68 is located above the conveying path 15 in the up-down direction 7, and between the first conveyance roller 41 and the laminating roller 50 in the front-rear direction 8. The first cutting unit 68 cuts the first member 101 between the third conveyance roller 43 and the laminating roller 50. The second cutting unit 69 is located downstream of the laminating roller 50 in the conveying direction 16. The second cutting unit 69 is located above the conveyance path 15 in the up-down direction 7, and in front of the laminating roller 50 in the front-rear direction 8. The second cutting unit 69 simultaneously cuts the first member 101 and the second member 102 that have been bonded together by the laminating roller 50.

[0070] The first cutting unit 68 has any configuration capable of cutting the first member 101. The second cutting unit 69 has any configuration capable of cutting the first member 101 and the second member 102. The first cutting unit 68 and the second cutting unit 69 may include, for example, a cutter carriage that receives a driving force from a cutting motor 85 (see FIG. 3) and moves in the left-right direction 9, and a cutter mounted on the cutter carriage, or may include a movable blade that receives a driving force from the cutting motor 85 and moves in the up-down direction 7, and a fixed blade facing the movable blade.

[0071] [Control unit 90 and its peripheral parts] As shown in FIG. 3, the control unit 90 includes a CPU 91, a ROM 92, a RAM 93, and an EEPROM 94. The ROM 92 stores programs for controlling various operations of the laminating device 1. The EEPROM 94 stores various data used when the above programs are executed. The RAM 93 is used as a storage area for temporarily recording various data used when the CPU 91 executes the above programs, and as an area for expanding data and programs. When the laminating device 1 is powered on, the programs stored in the ROM 92 are copied and transferred to the RAM 93. The CPU 91 executes the programs stored in the RAM 93. This allows the control unit 90 to perform various controls.

[0072] The ASIC 95 is connected to an operation unit 12 and a display unit 13. The operation unit 12 detects when an operation key is pressed and outputs a signal corresponding to the pressed operation key. The control unit 90 identifies the pressed operation key based on the output signal from the operation unit 12. The display unit 13 displays information related to the operation of the laminating device 1 on its screen based on instructions from the control unit 90.

[0073] The recording head 32 is connected to the ASIC 95. The control unit 90 outputs a signal corresponding to image data to the recording head 32 via the ASIC 95. The recording head 32 ejects ink from a plurality of nozzles 33 provided in the recording head 32 in response to the signal output from the control unit 90.

[0074] A slack sensor 63 is connected to the ASIC 95. The slack sensor 63 outputs a signal according to the amount of light detected by the light receiving element. The control unit 90 obtains the slack of the first member 101 between the first conveyance roller 41 and the second conveyance roller 42 based on the output signal of the light receiving element. A media sensor 64 is connected to the ASIC 95. The media sensor 64 outputs a signal according to the amount of light detected by the light receiving element. The control unit 90 detects the first member 101 being conveyed on the conveyance path 15 based on the output signal of the light receiving element.

[0075] [Various motors] The first to third motors 81 to 83, the CR motor 84, and the cutting motor 85 are connected to the ASIC 95. Drive circuits for controlling these motors are incorporated into the ASIC 95. The control unit 90 outputs drive signals for rotating each motor to the drive circuits corresponding to each motor. The drive circuits output control currents to the corresponding motors according to the drive signals output from the control unit 90. This causes the corresponding motors to rotate. Note that some of the above motors may be configured with the same motor. Alternatively, when a certain motor drives multiple elements, multiple motors may be provided instead of that motor.

[0076] The first motor 81 drives the first to third conveyor rollers 41 to 43. More specifically, the first motor 81 generates power to rotate the first to third conveyor rollers 41 to 43. The power generated by the first motor 81 is applied to the second roller 412, the fourth roller 422, and the sixth roller 432. The second roller 412, the fourth roller 422, and the sixth roller 432 receive power from the first motor 81 and rotate around their central axes in the left-right direction 9. Accordingly, the first roller 411, the third roller 421, and the fifth roller 431 also rotate around their central axes in the left-right direction 9.

[0077] The second motor 82 drives the first roll 111 and the intermediate roller 44. More specifically, the second motor 82 generates power to rotate the first roll 111 supported by the first holder 21 and the intermediate roller 44. The power generated by the second motor 82 is applied to the first holder 21 and the eighth roller 442. The first holder 21 receives power from the second motor 82 and applies a force to the first member 101 in a direction that pulls the first roll 111 back. The eighth roller 442 receives power from the second motor 82 and rotates around its central axis in the left-right direction 9. Accordingly, the seventh roller 441 also rotates around its central axis in the left-right direction 9.

[0078] The third motor 83 drives the second roll 112 and the laminating roller 50. The third motor 83 generates power to rotate the second roll 112 supported by the second holder 22 and the laminating roller 50. The power generated by the third motor 83 is applied to the second holder 22 and the second laminating roller 52. The second holder 22 receives power from the third motor 83 and applies a force to the second member 102 in a direction that pulls the second roll 112 back. The second laminating roller 52 receives power from the third motor 83 and rotates around its central axis in the left-right direction 9. Accordingly, the first laminating roller 51 also rotates around its central axis in the left-right direction 9.

[0079] The CR motor 84 generates a force that moves the carriage 31 in the left-right direction 9. The cutting motor 85 generates a force that operates the first cutting unit 68 and the second cutting unit 69.

[0080] A rotary encoder 86 that detects the amount of rotation of the first conveyor roller 41 is attached to the rotation shaft of the second roller 412. The rotary encoder 86 outputs a signal corresponding to the amount of rotation of the second roller 412. The control unit 90 obtains the amount of rotation of the first conveyor roller 41 based on the output signal of the rotary encoder 86. The rotary encoder 86 may also be attached to the rotation shaft of the first roller 411.

[0081] A rotary encoder 87 that detects the amount of rotation of the intermediate roller 44 is attached to the rotation shaft of the eighth roller 442. The rotary encoder 87 outputs a signal corresponding to the amount of rotation of the eighth roller 442. The control unit 90 obtains the amount of rotation of the intermediate roller 44 based on the output signal of the rotary encoder 87. The rotary encoder 87 may also be attached to the rotation shaft of the seventh roller 441.

[0082] The control unit 90 drives the first motor 81 to rotate the first to third conveyance rollers 41 to 43, drives the second motor 82 to rotate the intermediate roller 44 and apply a force to the first roll 111 in a direction to rewind the first member 101, and drives the third motor 83 to rotate the laminating roller 50 and apply a force to the second roll 112 in a direction to rewind the second member 102. The control unit 90 drives the CR motor 84 to move the carriage 31, and drives the cutting motor 85 to operate the first cutting unit 68 and the second cutting unit 69.

[0083] [Cutting position of first member 101] The following describes the case where the laminating device 1 continuously produces multiple laminated finished products 100. The area of ​​the first member 101 that corresponds to one laminated finished product 100 is referred to as the "recording area" or "page," and the downstream end of the first member 101 is referred to as the "leading edge P." For example, when continuously producing three laminated finished products 100, the first member 101 is cut at five cutting positions shown in FIG. 4. In FIG. 4, the direction from left to right is the conveying direction 16.

[0084] The five cutting positions are classified into four types. The leading edge cutting position C0 is located between the most downstream recording range of the first member 101 in the conveying direction 16 (recording range #1 in FIG. 4) and a first margin adjacent to the recording range downstream in the conveying direction 16. The first trailing edge cutting position C1 is located between two recording ranges adjacent to the first member 101 in the conveying direction 16 (recording ranges #1 and #2, and recording ranges #2 and #3 in FIG. 4). The second trailing edge cutting position C2 is located between the most upstream recording range of the first member 101 in the conveying direction 16 (recording range #3 in FIG. 4) and a second margin adjacent to the recording range upstream in the conveying direction 16. The third trailing edge cutting position C3 is located upstream of the most upstream recording range of the first member 101 in the conveying direction 16.

[0085] The first cutting unit 68 cuts the first member 101 at the third rear end cutting position C3. The second cutting unit 69 cuts the first member 101 at the leading end cutting position C0, the first rear end cutting position C1, and the second rear end cutting position C2. When the laminating device 1 continuously produces N (N is an integer greater than or equal to 2) laminated finished products 100, the number of leading end cutting positions C0, second rear end cutting positions C2, and third rear end cutting positions C3 is one each, and the number of first rear end cutting positions C1 is (N-1).

[0086] [First embodiment] The control unit 90 of the laminating apparatus 1 according to the first embodiment executes the laminating process shown in Fig. 5, and executes the high-temperature process shown in Fig. 6 in response to determining that the temperature of the first motor 81 has reached a reference value. These processes are executed by the CPU 91 executing a program stored in the RAM 93. Note that the second conveyor roller 42 and the third conveyor roller 43 play a minor role in the laminating process, and therefore, a description of the second conveyor roller 42 and the third conveyor roller 43 will be omitted below.

[0087] Before the lamination process is performed, the first member 101 pulled out from the first roll 111 is held only by the intermediate roller 44, and the leading end P of the first member 101 is located between the intermediate roller 44 and the first conveying roller 41. In addition, the leading end of the second member 102 pulled out from the second roll 112 is held by the laminating roller 50.

[0088] During lamination processing, the control unit 90 updates the count values ​​stored in the RAM 93 based on the output signals of the rotary encoders 86 and 87, and acquires the amount of rotation of the first conveying roller 41, the amount of rotation of the intermediate roller 44, and the position of the leading edge P of the first member 101 on the conveying path 15 based on the count values. Based on the acquired position of the leading edge P, the control unit 90 determines the area on the first member 101 where an image is recorded in one recording, and positions on the conveying path 15 such as the leading edge cutting position C0, the first trailing edge cutting position C1, the second trailing edge cutting position C2, and the third trailing edge cutting position C3.

[0089] Furthermore, the control unit 90 acquires the temperature Ta of the first motor 81 during the lamination process and compares the acquired temperature Ta with first to third reference values ​​TH1 to TH3. The temperature Ta is, for example, the ambient temperature of the first motor 81 or the temperature of the case of the first motor 81. The temperature Ta may be a predicted value predicted based on the control voltage or control current of the first motor 81, or may be a measured value measured by a thermometer provided near the first motor 81 or on the case. The temperature Ta may be a value calculated based on the predicted value and the measured value.

[0090] The first reference value TH1 is a temperature that serves as a reference for stopping the drive of the first motor 81. The second reference value TH2 is a temperature that serves as a reference for executing high-temperature processing. The third reference value TH3 is a temperature that serves as a reference for resuming the drive of the first motor 81. The first reference value TH1 is higher than the second reference value TH2, which is higher than the third reference value TH3. If the temperature of the first motor 81 rises by ΔT when one page of standard image is recorded on the first member 101, the first reference value TH1 is a temperature that is higher than the second reference value TH2 by ΔT or more, and the second reference value TH2 is a temperature that is higher than the third reference value TH3 by ΔT or more. For example, the first reference value TH1 is 100°C, the second reference value TH2 is 80°C, and the third reference value TH3 is 79.5°C.

[0091] 5 in response to receiving a job to record an image on the first member 101. The control unit 90 first determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S11). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S11: Yes), the control unit 90 proceeds to S11. If the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S11: No), the control unit 90 proceeds to S12. In the latter case, the control unit 90 drives the intermediate rollers 44 to transport the first member 101 until the leading edge P reaches the first transport rollers 41 (S12).

[0092] Next, the control unit 90 determines whether the temperature Ta is equal to or greater than the first reference value TH1 (S13). If the control unit 90 determines that the temperature Ta is equal to or greater than the first reference value TH1 (S13: Yes), the control unit 90 proceeds to S24, and if the control unit 90 determines that the temperature Ta is less than the first reference value TH1 (S13: No), the control unit 90 proceeds to S14.

[0093] In the latter case, the control unit 90 drives the first conveyance roller 41 and the intermediate roller 44 to convey the first member 101 to the next recording position (S14). In S14, the control unit 90 conveys the first member 101 until the next recording area of ​​the first member 101 (the area where an image will be recorded in the next recording) is positioned in the recording area of ​​the recording unit 30. In S14, the control unit 90 performs first position control in which the first motor 81 drives the first conveyance roller 41 to control the position of the first member 101, and second position control in which the second motor 82 drives the intermediate roller 44 to control the position of the first member 101. While the first member 101 is being conveyed, tension is applied to the first member 101.

[0094] Next, the control unit 90 drives the recording unit 30 to record an image in a predetermined range on the first member 101 (S15). In S15, the control unit 90 causes the recording head 32 to eject ink onto the recording surface 107 of the first member 101. As a result, an image is recorded on the portion of the first member 101 facing the recording head 32. Tension is applied to the first member 101 even while the first member 101 remains in the recording position.

[0095] In S14 and S15, the control unit 90 performs intermittent transport control, which alternately performs a transport operation in which the first transport roller 41 is controlled to transport the first member 101 to the recording position of the recording unit 30 while applying tension, and a recording operation in which the first transport roller 41 is controlled to keep the first member 101 at the recording position while applying tension, and the recording unit 30 is controlled to record an image on the first member 101. Here, the tension applied to the first member 101 between the intermediate roller 44 and the first transport roller 41 is referred to as a first tension. The transport operation is an operation in which the first motor 81 is driven to cause the first transport roller 41 to transport the first member 101 to the recording position of the recording unit 30 while applying the first tension to the first member 101 between the intermediate roller 44 and the first transport roller 41. The recording operation is an operation in which a first tension is applied to the first member 101 between the intermediate roller 44 and the first conveying roller 41, the first motor 81 is controlled to cause the first conveying roller 41 to keep the first member 101 at the recording position, and the recording unit 30 is controlled to record an image on the first member 101.

[0096] During execution of the intermittent conveyance control, the control unit 90 applies a first tension to the first member 101 between the intermediate roller 44 and the first conveyance roller 41, and also performs second tension application control by controlling the second motor 82 to apply a second tension to the first member 101 between the first roll 111 and the intermediate roller 44, third tension application control by controlling the third motor 83 to apply a third tension to the second member 102 between the second roll 112 and the laminating roller 50, and fourth tension application control to apply a fourth tension to the first member 101 between the first conveyance roller 41 and the laminating roller 50. During execution of the intermittent conveyance control, the control unit 90 controls the laminating roller 50 to continuously apply the fourth tension to the first member 101.

[0097] Next, the control unit 90 determines whether printing of one page is complete (S16). In S16, the control unit 90 determines that printing of one page is complete when the image data of the page currently being printed has run out. If the control unit 90 determines that printing of one page is complete (S16: Yes), it proceeds to S17, and if it determines that recording of the image of one page is not complete (S16: No), it proceeds to S13.

[0098] In the former case, the control unit 90 determines whether the temperature Ta is equal to or greater than the second reference value TH2 (S17). If the control unit 90 determines that the temperature Ta is equal to or greater than the second reference value TH2 (S17: Yes), the control unit 90 proceeds to S25, and if the control unit 90 determines that the temperature Ta is less than the second reference value TH2 (S17: No), the control unit 90 proceeds to S18.

[0099] In the latter case, the control unit 90 determines whether all jobs have been completed (S18). In S18, the control unit 90 determines that all jobs have been completed when there is no job to be executed next. If the control unit 90 determines that all jobs have been completed (S18: Yes), the control unit 90 proceeds to S19, and if it determines that there is an incomplete job (S18: No), the control unit 90 proceeds to S13.

[0100] In the former case, the control unit 90 causes the first conveyance rollers 41 and the intermediate rollers 44 to convey the first member 101 to the third trailing end cutting position C3 (S19). In S19, the control unit 90 drives the first conveyance rollers 41 and the intermediate rollers 44 to convey the first member 101 until the third trailing end cutting position C3 reaches the cutting position of the first cutting unit 68. Next, the control unit 90 drives the first cutting unit 68 to cut the first member 101 at the third trailing end cutting position C3 (S20).

[0101] Next, the control unit 90 causes the first conveyance roller 41 and the intermediate roller 44 to convey the first member 101 to a rewinding position (S21). In parallel with this, the control unit 90 sequentially executes a process of conveying the first member 101 to a second trailing end cutting position C2 by the laminating roller 50 (S22) and a process of cutting the first member 101 at the second trailing end cutting position C2 (S23).

[0102] In S21, the control unit 90 drives the first conveyor roller 41 and the intermediate roller 44 in the opposite directions to rewind the upstream side of the first member 101 cut at the third rear end cutting position C3 until the leading edge P of the first member 101 reaches the rewinding position. Here, the rewinding position is a position between the intermediate roller 44 and the first conveyor roller 41. In other words, the rewinding position is a position where the first member 101 is not gripped by the first conveyor roller 41.

[0103] In S22, the control unit 90 drives the laminating roller 50 to transport the first member 101 until the second trailing end cutting position C2 on the downstream side of the first member 101 cut at the third trailing end cutting position C3 reaches the cutting position of the second cutting unit 69. In S23, the control unit 90 stops driving the laminating roller 50 and drives the second cutting unit 69 to cut the first member 101 at the second trailing end cutting position C2.

[0104] After executing S21 and S23, the control unit 90 ends the laminating process. Note that while the control unit 90 is causing the first member 101 to be conveyed in S14, S19, and S22, the leading edge cutting position C0 or the first trailing edge cutting position C1 may reach the second cutting unit 69. In this case, the control unit 90 stops driving the laminating roller 50 and drives the second cutting unit 69 to cut the first member 101 at that position.

[0105] If the control unit 90 determines in S13 that the temperature Ta is equal to or greater than the first reference value TH1, the process proceeds to S24. In this case, the control unit 90 stops the supply of control voltage to the first motor 81, thereby stopping the first motor 81 (S24). After executing S24, the control unit 90 ends the laminating process.

[0106] If the control unit 90 determines in S17 that the temperature Ta is equal to or higher than the second reference value TH2, the process proceeds to S25. In this case, the control unit 90 executes high temperature processing (S25) and proceeds to S11.

[0107] 6, the control unit 90 first updates the second trailing end cutting position C2 and the third trailing end cutting position C3 (S111). When the length of the recording range in the conveying direction 16 is L, in S111 the control unit 90 sets the first trailing end cutting position C1, which is located between the recording range in which the last image was recorded and the recording range in which the next image was to be recorded, as the updated second trailing end cutting position C2, and sets a position that is the distance L upstream in the conveying direction 16 from the updated second trailing end cutting position C2 as the updated third trailing end cutting position C3.

[0108] Next, the control unit 90 controls the first conveyance roller 41 and the intermediate roller 44 to convey the first member 101 to the updated third trailing end cutting position C3 (S112). In S112, the control unit 90 operates in the same manner as in S19. As a result, the first member 101 is conveyed to a position where the portion on which the image is recorded is downstream of the first cutting unit 68 in the conveying direction 16.

[0109] Next, the control unit 90 stops the application of the fourth tension from the laminating roller 50 to the first member 101 (S113). In S113, the control unit 90 stops the driving of the third motor 83, thereby stopping the laminating roller 50 and stopping the application of the fourth tension from the laminating roller 50. Next, the control unit 90 cuts the first member 101 at the updated third trailing end cutting position C3 (S114). In S114, the control unit 90 operates in the same manner as in S20.

[0110] Next, the control unit 90 causes the first conveyance roller 41 and the intermediate roller 44 to convey the first member 101 to the rewinding position (S115). In parallel with this, the control unit 90 sequentially executes a process of conveying the first member 101 to the updated second trailing end cutting position C2 by the laminating roller 50 (S116) and a process of cutting the first member 101 at the updated second trailing end cutting position C2 (S117).

[0111] In S115, the control unit 90 drives the first conveyance roller 41 and the intermediate roller 44 in the reverse direction to rewind the upstream side of the first member 101 cut at the third trailing end cutting position C3 until the leading edge P of the first member 101 reaches the rewinding position. In S115, the control unit 90 drives the first motor 81 and the second motor 82 to convey the first member 101 by the first conveyance roller 41 and the intermediate roller 44 in the direction opposite to the conveyance direction 16 until the first member 101 is not gripped by the first conveyance roller 41. S115 is an example of reverse conveyance control. The control unit 90 operates in the same manner as in S22 in S116 and in the same manner as in S23 in S117. After executing S115 and S117, the control unit 90 ends the high-temperature process.

[0112] In the first embodiment, the control unit 90 determines whether the temperature Ta has reached the second reference value TH2 after printing one page is completed, and performs the reverse conveyance control in response to the determination that the temperature Ta has reached the second reference value TH2 during execution of the intermittent conveyance control.

[0113] In the first embodiment, the first member 101 is an example of a member. The first conveying roller 41 is an example of a conveying mechanism. The first motor 81 is an example of a drive unit and a motor. The tension generating unit 60 is an example of a tension applying unit. The second reference value TH2 is an example of a first value. The rewinding position is an example of a position where the sheet is not gripped by the conveying mechanism. The intermediate roller 44 is an example of a second conveying mechanism. The second motor 82 is an example of a second drive unit. The first reference value TH1 is an example of a second value. The laminating roller 50 is an example of a second tension applying unit. The first cutting unit 68 is an example of a cutting unit. The fourth tension is an example of tension applied to a member between the conveying mechanism and the second tension applying unit. The second member 102 is an example of another member.

[0114] [Effects of the first embodiment] As described above, the laminating apparatus 1 according to the first embodiment includes the first conveyor roller 41 (conveyance mechanism), the first motor 81 (drive unit), the tension generating unit 60 (tension applying unit), and the control unit 90. The tension generating unit 60 applies tension to the first member 101 between the first conveyor roller 41 and the tension generating unit 60. In response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (first value) (S17: Yes), the control unit 90 performs reverse conveyance control (S115) in the high-temperature treatment (S25) to drive the first motor 81 to convey the first member 101 by the first conveyor roller 41 in a direction opposite to the conveyance direction 16 to a rewind position where the first member 101 is not gripped by the first conveyor roller 41.

[0115] Thus, in the laminating apparatus 1 according to the first embodiment, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 drives the first motor 81 to transport the first member 101 to a rewinding position where the first member 101 is not gripped by the first conveyor roller 41. Therefore, the tension applied to the first member 101 by the tension generating unit 60 is released, the temperature rise of the first motor 81 is suppressed, and the leading end P of the first member 101 is positioned between the first conveyor roller 41 and the tension generating unit 60, so that the laminating apparatus 1 can be easily restarted.

[0116] Generally, when restarting a conveying device that does not have a leading edge detection sensor for a workpiece, the leading edge position of the workpiece is identified by the register of the conveying mechanism or a workpiece sensor located upstream of the conveying mechanism, so the leading edge of the workpiece must be positioned between the conveying mechanism and the tension applying unit. In this case, simply stopping the drive unit and releasing the tension on the workpiece makes it unclear where the leading edge of the workpiece is located, which results in inconsistency in the leading edge position when the workpiece is rewound by the conveying mechanism upon restart. In the laminating device 1 according to the first embodiment, the leading edge position of the first workpiece 101 before stopping the first motor 81 can be determined based on the conveyance distance of the first conveying roller 41. This allows for accurate determination of the rewind distance and stabilizes the leading edge position of the first workpiece 101 after rewinding. This allows for easy restarting of the laminating device 1.

[0117] The laminating apparatus 1 further includes an intermediate roller 44 (second conveyance mechanism) and a second motor 82 (second drive unit), and the tension generating unit 60 applies tension to the first member 101 between the first conveyance roller 41 and the intermediate roller 44. In response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (S17: Yes), the control unit 90 controls the second motor 82 to convey the first member 101 upstream using the intermediate roller 44. Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the first member 101, including the leading end P rewound by the first conveyance roller 41, no longer sags, and the leading end position of the first member 101 is stabilized. This allows the laminating apparatus 1 to be easily restarted.

[0118] Furthermore, the first motor 81 is a motor, and in response to determining that the temperature Ta of the first motor 81 has reached a first reference value TH1 (second value) that is higher than the second reference value TH2 (S13: Yes), the control unit 90 stops supplying the control voltage to the first motor 81 (S24). Therefore, when the temperature Ta of the first motor 81 reaches the first reference value TH1, the temperature rise of the first motor 81 can be suppressed, and the first motor 81 can be protected.

[0119] The laminating apparatus 1 further includes a recording unit 30, and the tension generating unit 60 is configured not to apply tension to the first member 101 when the length of the first member 101 between the first conveying roller 41 and the intermediate roller 44 is equal to or greater than a predetermined length, and to apply tension to the first member 101 when the length is less than the predetermined length. In response to acquiring a job to record an image on the first member 101, the control unit 90 performs intermittent conveyance control that alternately performs a conveying operation (S14) in which the first conveying roller 41 is controlled to apply tension to convey the first member 101 to a recording position of the recording unit 30, and a recording operation (S15) in which the first conveying roller 41 is controlled to apply tension to keep the first member 101 at the recording position, and the recording unit 30 is controlled to record an image on the first member 101. The control unit 90 performs reverse conveyance control (S115) in the high temperature process (S25) in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 while the intermittent conveyance control is being executed (S17: Yes). Therefore, if the temperature Ta of the first motor 81 reaches the second reference value TH2 while the intermittent conveyance control is being executed, the laminating device 1 can be easily restarted after the first motor 81 has been stopped due to heat generation.

[0120] When the control unit 90 determines that the temperature Ta of the first motor 81 has reached the second reference value TH2 during execution of the intermittent conveyance control (S17: Yes), it performs reverse conveyance control (S115) for each printing of a page specified in the job. Therefore, when the temperature Ta of the first motor 81 has reached the second reference value TH2 during execution of the intermittent conveyance control, the laminating device 1 can be easily restarted after the first motor 81 has been stopped due to heat generation by conveying the first member 101 to a position where it is not gripped by the first conveyance roller 41.

[0121] The laminating apparatus 1 further includes a laminating roller 50 (second tension applying unit) and a first cutting unit 68 (cutting unit). The laminating roller 50 applies a fourth tension (tension) to the first member 101 between the first conveyance roller 41 and the laminating roller 50. During execution of the intermittent conveyance control, the control unit 90 controls the laminating roller 50 to continuously apply the fourth tension to the first member 101 between the first conveyance roller 41 and the laminating roller 50, and during execution of the intermittent conveyance control, in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (S17: Yes), the control unit 90 controls the first cutting unit 68 to cut the first member 101 (S114), and then performs reverse conveyance control (S115). In this way, while the intermittent conveying control is being executed, tension is continuously applied to the first member 101 from the laminating roller 50 in the conveying direction 16, and when the temperature Ta of the first motor 81 reaches the second reference value TH2 while the intermittent conveying control is being executed, the first member 101 is cut between the first conveying roller 41 and the laminating roller 50, and the first conveying roller 41 is controlled to convey the cut first member 101 to a rewind position where it is not gripped by the first conveying roller 41, thereby allowing the laminating device 1 to be easily restarted after the first motor 81 is stopped due to heat generation.

[0122] Furthermore, when the control unit 90 determines that the temperature Ta of the first motor 81 has reached the second reference value TH2 during intermittent conveying control (S17: Yes), it controls the first conveying roller 41 to convey the first member 101 to a position where the portion on which the image is recorded is downstream of the first cutting unit 68 in the conveying direction 16 (S112), controls the first cutting unit 68 to cut the first member 101 (S114), and performs reverse conveying control (S115). In this way, when the temperature Ta of the first motor 81 reaches the second reference value TH2 while the intermittent conveying control is being performed, the first conveying roller 41 is controlled to convey the first member 101 to a position where the portion on which the image is recorded is downstream of the first cutting section 68, the first member 101 is cut between the first conveying roller 41 and the laminating roller 50, and the first conveying roller 41 is controlled to convey the cut first member 101 to a rewinding position where it is not gripped by the first conveying roller 41, thereby making it possible to easily restart the laminating device 1 after the first motor 81 has been stopped due to heat generation.

[0123] Furthermore, in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 during execution of the intermittent conveyance control (S17: Yes), the control unit 90 controls the laminating roller 50 to stop applying the fourth tension (tension) to the first member 101 between the first conveyance roller 41 and the laminating roller 50 (S113), and then controls the first cutting unit 68 to cut the first member 101 (S114), and performs reverse conveyance control (S115). In this way, when the temperature Ta of the first motor 81 reaches the second reference value TH2 during execution of the intermittent conveyance control, the application of tension to the first member 101 is stopped, the first member 101 is cut between the first conveyance roller 41 and the laminating roller 50, and the first conveyance roller 41 is controlled to convey the first member 101 to an unwinding position where it is not gripped by the first conveyance roller 41, thereby making it possible to easily restart the laminating apparatus 1 after the first motor 81 has been stopped due to heat generation.

[0124] The laminating apparatus 1 further includes a laminating roller 50 and a first cutting unit 68 (first cutting unit). In response to determining that the temperature Ta of the first motor 81 has reached a second reference value (first value) (S17: Yes), the control unit 90 controls the first cutting unit 68 to cut the first member 101 (S114), and then performs reverse conveyance control (S115). In this way, in the laminating apparatus 1 including the laminating roller 50 and the first cutting unit 68, when the temperature Ta of the first motor 81 has reached the first value, the first member 101 is cut between the first conveyance roller 41 and the laminating roller 50, and the first conveyance roller 41 is controlled to convey the first member 101 to a position where it is not gripped by the first conveyance roller 41. This makes it possible to easily restart the laminating apparatus 1 after the first motor 81 has been stopped due to heat generation.

[0125] [Modification of the first embodiment] Various modifications can be made to the laminating device 1 according to the first embodiment. The control unit 90 of the laminating device 1 according to the first modification executes the laminating process shown in Fig. 7 instead of the laminating process shown in Fig. 5. The flowchart shown in Fig. 7 is the same as the flowchart shown in Fig. 5, except that S16 is replaced with S31.

[0126] 7, after executing S15, the control unit 90 proceeds to S31. Next, the control unit 90 determines whether one job has been completed (S31). If the control unit 90 determines that one job has been completed (S31: Yes), it proceeds to S17, and if the control unit 90 determines that one job has not been completed (S31: No), it proceeds to S13.

[0127] In the first modified example, the control unit 90 determines whether the temperature Ta has reached the second reference value TH2 after completing one job, and performs reverse conveyance control if the determination is Yes. In this way, the control unit 90 performs reverse conveyance control after completing all intermittent conveyance control related to the job if the control unit 90 determines that the temperature Ta of the first motor 81 has reached the second reference value TH2 during execution of intermittent conveyance control. According to the laminating apparatus 1 of the first modified example, if the temperature Ta of the first motor 81 has reached the second reference value TH2 during execution of intermittent conveyance control, the laminating apparatus 1 can easily restart operation after the first motor 81 has been stopped due to heat generation by controlling the first conveyance rollers 41 to convey the first member 101 to a position where it is not gripped by the first conveyance rollers 41 after the job is completed.

[0128] The control unit 90 of the laminating apparatus 1 according to the second modified example executes the laminating process shown in Fig. 8 instead of the laminating process shown in Fig. 5. The flowchart shown in Fig. 8 is the same as the flowchart shown in Fig. 5 except that S11, S13, and S17 are replaced with S41, S42, and S43, respectively.

[0129] During the laminating process, the control unit 90 acquires the temperature Tb of the second motor 82 in addition to the temperature Ta of the first motor 81, and compares the maximum value of the two acquired temperatures Ta and Tb (hereinafter referred to as the "maximum temperature Tm") with the first to third reference values ​​TH1 to TH3. The temperature Tb is acquired, for example, in the same manner as the temperature Ta.

[0130] In S41, the control unit 90 determines whether the maximum temperature Tm is equal to or greater than the third reference value TH3. If the control unit 90 determines that the maximum temperature Tm is equal to or greater than the third reference value TH3 (S41: Yes), the control unit 90 proceeds to S41, and if the control unit 90 determines that the maximum temperature Tm is less than the third reference value TH3 (S41: No), the control unit 90 proceeds to S12.

[0131] In S42, the control unit 90 determines whether the maximum temperature Tm is equal to or greater than the first reference value TH1. If the control unit 90 determines that the maximum temperature Tm is equal to or greater than the first reference value TH1 (S42: Yes), the control unit 90 proceeds to S24, and if the control unit 90 determines that the maximum temperature Tm is less than the first reference value TH1 (S42: No), the control unit 90 proceeds to S14.

[0132] In S43, the control unit 90 determines whether the maximum temperature Tm is equal to or greater than the second reference value TH2. If the control unit 90 determines that the maximum temperature Tm is equal to or greater than the second reference value TH2 (S43: Yes), the control unit 90 proceeds to S25, and if the control unit 90 determines that the maximum temperature Tm is less than the second reference value TH2 (S43: No), the control unit 90 proceeds to S18. In the former case, the control unit 90 executes the high-temperature process shown in FIG. 6 (S25).

[0133] The laminating apparatus 1 according to the second modified example further includes an intermediate roller 44 (second conveying mechanism) and a second motor 82 (second driving unit), and the control unit 90 performs reverse conveyance control (S115) in response to determining that the temperature Tb of the second motor 82 has reached the second reference value TH2 (S43: Yes). Therefore, even when the temperature Tb of the second motor 82 has reached the second reference value TH2, the laminating apparatus 1 can be easily restarted after the first motor 81 has been stopped due to heat generation by controlling the first conveying roller 41 to convey the first member 101 to a rewinding position where it is not gripped by the first conveying roller 41.

[0134] [Second embodiment] The control unit 90 of the laminating apparatus 1 according to the second embodiment executes the laminating process shown in Fig. 9, and when it determines that at least one of the temperatures of the first to third motors 81 to 83 has reached a reference value, executes the high-temperature process shown in Fig. 10. The flowchart shown in Fig. 9 is the same as the flowchart shown in Fig. 5, except that S11, S13, and S17 are replaced with S51, S52, and S53, respectively.

[0135] During the laminating process, the control unit 90 acquires the temperature Tb of the second motor 82 and the temperature Tc of the third motor 83 in addition to the temperature Ta of the first motor 81, and compares the maximum value of the acquired three temperatures Ta, Tb, and Tc (hereinafter referred to as the "maximum temperature Tn") with the first to third reference values ​​TH1 to TH3. The temperatures Tb and Tc are acquired, for example, in the same manner as the temperature Ta.

[0136] In S51, the control unit 90 determines whether the maximum temperature Tn is equal to or greater than the third reference value TH3. If the control unit 90 determines that the maximum temperature Tn is equal to or greater than the third reference value TH3 (S51: Yes), the control unit 90 proceeds to S51, and if the control unit 90 determines that the maximum temperature Tn is less than the third reference value TH3 (S51: No), the control unit 90 proceeds to S12.

[0137] In S52, the control unit 90 determines whether the maximum temperature Tn is equal to or greater than the first reference value TH1. If the control unit 90 determines that the maximum temperature Tn is equal to or greater than the first reference value TH1 (S52: Yes), the control unit 90 proceeds to S24, and if the control unit 90 determines that the maximum temperature Tn is less than the first reference value TH1 (S52: No), the control unit 90 proceeds to S14.

[0138] In S53, the control unit 90 determines whether the maximum temperature Tn is equal to or greater than the second reference value TH2. If the control unit 90 determines that the maximum temperature Tn is equal to or greater than the second reference value TH2 (S53: Yes), the control unit 90 proceeds to S25, and if the control unit 90 determines that the maximum temperature Tn is less than the second reference value TH2 (S53: No), the control unit 90 proceeds to S18. In the former case, the control unit 90 executes the high-temperature process shown in FIG. 10 (S25).

[0139] Like the control unit 90 according to the first embodiment, during execution of the intermittent conveying control (S14, S15), the control unit 90 controls the laminating roller 50 to continuously apply tension to the first member 101, and also controls the second motor 82 to perform second tension application control to apply second tension to the first member 101 between the first roll 111 and the intermediate roller 44, and third tension application control to control the third motor 83 to apply third tension to the second member 102 between the second roll 112 and the laminating roller 50.

[0140] 10, the control unit 90 first stops driving the first to third motors 81 to 83 (S211). In S211, the control unit 90 stops supplying control voltages to the first to third motors 81 to 83, thereby stopping driving the first to third motors 81 to 83. S211 is an example of stop control.

[0141] Next, the control unit 90 determines whether the minimum value of the three temperatures Ta, Tb, and Tc is equal to or greater than a third reference value TH3 (S212). If the control unit 90 determines that the minimum value is equal to or greater than the third reference value TH3 (S212: Yes), it proceeds to S212, and if the control unit 90 determines that the minimum value is less than the third reference value TH3 (S212: No), it proceeds to S213. Next, the control unit 90 resumes driving the first to third motors 81 to 83 (S213). After executing S213, the control unit ends the high-temperature processing.

[0142] In the second embodiment, the first holder 21 is an example of a first support portion. The second holder 22 is an example of a second support portion. The first conveying roller 41 is an example of a first conveying mechanism. The first motor 81 is an example of a first driving portion. The intermediate roller 44 is an example of a second conveying mechanism. The second motor 82 is an example of a second driving portion. The first cutting portion 68 is an example of a cutting portion. The third motor 83 is an example of a third driving portion. The second reference value TH2 is an example of a first value.

[0143] [Effects of the second embodiment] As described above, the laminating device 1 according to the second embodiment includes a first holder 21 (first support section), a second holder 22 (second support section), a first conveying roller 41 (first conveying mechanism), a first motor 81 (first drive section), an intermediate roller 44 (second conveying mechanism), a second motor 82 (second drive section), a recording section 30, a first cutting section 68 (cutting section), a bonding roller 50, a third motor 83 (third drive section), and a control section 90.

[0144] The control unit 90 performs intermittent conveyance control (S14, S15), second tension application control, and third tension application control, similar to the control unit 90 according to the first embodiment. When the control unit 90 determines that the maximum temperature Tn of the first to third motors 81 to 83 (the temperature of at least one of the first to third motors 81 to 83) has reached the second reference value TH2 during the execution of the intermittent conveyance control (S43: Yes), the control unit 90 performs stop control (S211) to stop driving of the first to third motors 81 to 83 in the high temperature process shown in FIG.

[0145] Therefore, according to the laminating device 1 of the second embodiment, when the maximum temperature Tn of the first to third motors 81 to 83 reaches the second reference value TH2 while intermittent conveying control is being performed, the driving of the first to third motors 81 to 83 is stopped, thereby suppressing the temperature rise of the first to third motors 81 to 83 and allowing the laminating device 1 to be easily restarted.

[0146] [Third embodiment] The control unit 90 of the laminating device 1 of the third embodiment performs the laminating process shown in Figure 5, and, depending on whether it determines that the temperature Ta of the first motor 81 has reached the second reference value TH2, performs one of the three types of high-temperature processes shown in Figures 11 and 12.

[0147] Like the control unit 90 according to the first embodiment, during execution of intermittent conveying control, the control unit 90 performs a first position control in which the position of the first member 101 is controlled by driving the first conveying roller 41, and a second position control in which the second motor 82 controls the position of the first member 101 by driving the intermediate roller 44 (see Figure 13(A)).

[0148] In S25 shown in Figure 5, the control unit 90 executes one of the first example of high temperature processing shown in Figure 11(A), the second example of high temperature processing shown in Figure 11(B), and the third example of high temperature processing shown in Figure 12.

[0149] In the first example of high temperature processing (FIG. 11A), the control unit 90 first stops the first position control of the first member 101 by the first conveying roller 41 (S311). At this time, the control unit 90 continues the second position control of the first member 101 by the intermediate roller 44 (see FIG. 13B).

[0150] Next, the control unit 90 acquires the rotation amount (hereinafter referred to as the rotation amount R1) of the first conveyor roller 41 from the rotary encoder 86 (S312). Next, the control unit 90 stores the rotation amount R1 of the first conveyor roller 41 acquired in S312 in the RAM 93 (S313).

[0151] Next, the control unit 90 determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S314). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S314: Yes), the control unit 90 proceeds to S314, and if the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S314: No), the control unit 90 proceeds to S315.

[0152] In the latter case, the control unit 90 controls the first motor 81 to cause the first conveyance roller 41 to convey the first member 101 based on the rotation amount R1 stored in the RAM 93 (S315). In S315, the first member 101 is conveyed until the media sensor 64 detects the first member 101. After executing S315, the control unit 90 ends the high temperature processing of the first example.

[0153] In the second example of high temperature processing (FIG. 11B), the control unit 90 first stops the second position control of the first member 101 by the intermediate roller 44 (S321). At this time, the control unit 90 continues the first position control of the first member 101 by the first conveying roller 41 (see FIG. 13C).

[0154] Next, the control unit 90 acquires the rotation amount of the intermediate roller 44 (hereinafter referred to as the rotation amount R2) from the rotary encoder 87 (S322). Next, the control unit 90 stores the rotation amount R2 of the intermediate roller 44 acquired in S322 in the RAM 93 (S323).

[0155] Next, the control unit 90 determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S324). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S324: Yes), the control unit 90 proceeds to S324, and if the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S324: No), the control unit 90 proceeds to S325.

[0156] In the latter case, the control unit 90 controls the second motor 82 to cause the intermediate rollers 44 to transport the first member 101 based on the rotation amount R2 stored in the RAM 93 (S325). In S325, the control unit 90 controls the intermediate rollers 44 to transport the first member 101 in the direction opposite to the transport direction 16 until the slack sensor 63 detects that the abutting member 61 is located at the first position where tension is applied to the first member 101. In S325, the first member 101 may be transported until the media sensor 64 detects the first member 101.

[0157] Next, the control unit 90 conveys the first member 101 until it is detected by the media sensor 64 (S326). In S326, the control unit 90 controls the first conveyance roller 41 to convey the first member 101 until the media sensor 64 detects the first member 101. After executing S326, the control unit 90 ends the high temperature processing of the second example.

[0158] In the third example of high temperature processing (FIG. 12), the control unit 90 first stops the first position control of the first member 101 by the first conveyor roller 41 and the second position control of the first member 101 by the intermediate roller 44 (S331).

[0159] Next, the control unit 90 acquires the rotation amount R1 of the first conveyor roller 41 from the rotary encoder 86 (S332). Next, the control unit 90 acquires the rotation amount R2 of the intermediate roller 44 from the rotary encoder 87 (S333). Next, the control unit 90 stores the rotation amount R1 of the first conveyor roller 41 acquired in S332 and the rotation amount R2 of the intermediate roller 44 acquired in S333 in the RAM 93 (S334).

[0160] Next, the control unit 90 determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S335). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S335: Yes), the control unit 90 proceeds to S335, and if the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S335: No), the control unit 90 proceeds to S336.

[0161] In the latter case, the control unit 90 controls the first motor 81 to cause the first conveyance roller 41 to convey the first member 101 based on the first rotation amount R1 stored in the RAM 93 (S336). Next, the control unit 90 controls the second motor 82 to cause the intermediate roller 44 to convey the first member 101 based on the second rotation amount R2 stored in the RAM 93 (S337). Note that the control unit 90 may execute S336 and S337 in parallel, or may execute S336 after executing S337.

[0162] Next, the control unit 90 conveys the first member 101 until it is detected by the media sensor 64 (S337). In S337, the control unit 90 operates in the same manner as in S326. After executing S327, the control unit 90 ends the high temperature process of the third example.

[0163] In the third embodiment, the first member 101 is an example of a member. The first conveying roller 41 is an example of a first conveying mechanism. The first motor 81 is an example of a first driving unit. The intermediate roller 44 is an example of a second conveying mechanism. The second motor 82 is an example of a second driving unit. The tension generating unit 60 is an example of a tension applying unit. The second reference value TH2 is an example of a first value. The rotary encoder 86 is an example of an encoder and a first encoder. The third reference value TH3 is an example of a third value. The rotary encoder 87 is an example of an encoder and a second encoder. The abutting member 61 is an example of a moving member. The slack sensor 63 is an example of a sensor. The media sensor 64 is an example of a member sensor. The rotation amount R1 is an example of a first rotation amount. The rotation amount R2 is an example of a second rotation amount.

[0164] [Effects of the third embodiment] As described above, the laminating apparatus 1 according to the third embodiment includes the first conveyor rollers 41 (first conveyor mechanism), the first motor 81 (first drive unit), the intermediate rollers 44 (second conveyor mechanism), the second motor 82 (second drive unit), the tension generating unit 60 (tension applying unit), and the control unit 90. In response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (first value) (S17: Yes), the control unit 90 stops at least one of the first position control in which the first motor 81 drives the first conveyor rollers 41 to control the position of the first member 101 (member) and the second position control in which the second motor 82 drives the intermediate rollers 44 to control the position of the first member 101 in the high-temperature treatment (S25) (S311, S321, S331).

[0165] Therefore, in the laminating apparatus 1 according to the third embodiment, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops at least one of the first position control and the second position control. As a result, the first conveyance roller 41 and / or the intermediate roller 44, which no longer perform position control of the first member 101, move to release the tension applied to the first member 101. This releases the tension, suppressing the temperature rise of the stopped first motor 81 and / or second motor 82. The control unit 90 can also determine whether to stop driving the first motor 81, the second motor 82, or both. The direction in which the first member 101 moves depends on the motor that stops position control, allowing the laminating apparatus 1 to be easily restarted.

[0166] In the first example, in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (S17: Yes), the control unit 90 stops the first position control and continues the second position control (S311) during the high-temperature process shown in FIG. 11A. Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops the first position control, thereby releasing the tension applied to the first member 101 between the first conveyance roller 41 and the intermediate roller 44. This makes it possible to suppress a temperature rise in the first motor 81. Furthermore, since it is known in advance that the first member 101 located upstream of the first conveyance roller 41 will be conveyed further upstream than the first conveyance roller 41, the laminating apparatus 1 can be easily restarted.

[0167] The laminating device 1 further includes a rotary encoder 86 (encoder), and after the control unit 90 stops the first position control, it stores the rotation amount R1 of the first conveying roller 41 detected by the rotary encoder 86, and upon determining that the temperature Ta of the first motor 81 has dropped below a third reference value TH3 (third value) that is lower than the second reference value TH2 (S314: No), it controls the first motor 81 based on the stored rotation amount R1 to cause the first conveying roller 41 to convey the first member 101 (S315).

[0168] In this way, the control unit 90 stops the first position control when the temperature Ta of the first motor 81 reaches the second reference value TH2, and when the temperature Ta thereafter drops below the third reference value TH3, the control unit 90 controls the first motor 81 based on the stored rotation amount R1 of the first motor 81 to transport the first member 101. This allows the first member 101 to be transported in the transport direction 16 by the amount that the first transport roller 41 was driven in the direction in which the tension is released, so that the laminating device 1 can be easily restarted.

[0169] In the second example, in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (S17: Yes), the control unit 90 continues the first position control and stops the second position control (S321) during the high-temperature process shown in FIG. 11(B). Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops the second position control, thereby releasing the tension applied to the first member 101 between the first conveyance roller 41 and the intermediate roller 44. This makes it possible to suppress a temperature rise in the second motor 82. Furthermore, since it is known in advance that the first member 101 located upstream of the intermediate roller 44 will be conveyed further upstream of the intermediate roller 44, the laminating apparatus 1 can be easily restarted.

[0170] In addition, the laminating device 1 further includes a rotary encoder 87 (encoder), and after the control unit 90 stops the second position control, it stores the rotation amount R2 of the intermediate roller 44 detected by the rotary encoder 87, and upon determining that the temperature Ta of the first motor 81 has fallen below a third reference value TH3 that is lower than the second reference value TH2 (S324: No), it controls the second motor 82 based on the stored rotation amount R2 to cause the intermediate roller 44 to transport the first member 101 (S325).

[0171] In this way, the control unit 90 stops the second position control when the temperature Ta of the first motor 81 reaches the second reference value TH2, and when the temperature Ta thereafter drops below the third reference value TH3, the control unit 90 controls the intermediate roller 44 based on the stored rotation amount R2 of the intermediate roller 44 to transport the first member 101. This allows the first member 101 to be transported in the transport direction 16 by the amount that the intermediate roller 44 was driven in the direction in which the tension is released, so that the laminating device 1 can be easily restarted.

[0172] Furthermore, the tension applying unit (tension generating unit 60) includes a contact member 61 (moving member), and the laminating apparatus 1 further includes a slack sensor 63 (sensor). After stopping the driving of the second motor 82, the control unit 90 may control the intermediate rollers 44 to convey the first member 101 in the opposite direction to the conveying direction 16 until the slack sensor 63 detects that the contact member 61 is located at the first position. Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops the driving of the second motor 82 and controls the second motor 82 to convey the first member 101 in the opposite direction to the conveying direction 16 until the slack sensor 63 detects that the contact member 61 is located at the first position, thereby applying a desired tension to the first member 101 between the first conveying rollers 41 and the intermediate rollers 44.

[0173] In the third example, the control unit 90, upon determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (S17: Yes), stops the first position control and the second position control (S331) in the high-temperature process shown in FIG. 12. Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops the first position control and the second position control, thereby releasing the tension applied to the first member 101 between the first conveyance roller 41 and the intermediate roller 44. This suppresses temperature increases in the first motor 81 and the second motor 82. Furthermore, since it is known in advance that the first member 101 located upstream of the first conveyance roller 41 will be conveyed further upstream than the first conveyance roller 41, and the first member 101 located upstream of the intermediate roller 44 will be conveyed further upstream than the intermediate roller 44, the laminating apparatus 1 can be easily restarted.

[0174] The laminating device 1 further includes rotary encoders 86 and 87, and after the control unit 90 stops the first position control and the second position control, it stores the rotation amount R1 (first rotation amount) of the first conveying roller 41 detected by the rotary encoder 86 and the rotation amount R2 (second rotation amount) of the intermediate roller 44 detected by the rotary encoder 87. When it determines that the temperature Ta of the first motor 81 has fallen below a third reference value TH3 that is lower than the second reference value TH2 (S335: No), it controls the first motor 81 based on the stored first rotation amount R1 to cause the first conveying roller 41 to convey the first member 101 (S336), and controls the second motor 82 based on the stored second rotation amount R2 to cause the intermediate roller 44 to convey the first member 101 (S337).

[0175] In this way, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the control unit 90 stops the first position control and the second position control, and when the temperature Ta thereafter drops below the third reference value TH3, the control unit 90 controls the first conveyance mechanism based on the stored rotation amount R1 of the first conveyance roller 41 to convey the first member 101, and controls the intermediate roller 44 based on the stored rotation amount R2 of the intermediate roller 44 to convey the first member 101. This allows the first member 101 to be conveyed in the conveyance direction 16 by the amount that the first conveyance roller 41 was driven so as to release the tension, and the first member 101 to be conveyed in the conveyance direction 16 by the amount that the intermediate roller 44 was driven so as to release the tension, so that the laminating apparatus 1 can be easily restarted.

[0176] The laminating apparatus 1 further includes a media sensor 64 (member sensor). In the high-temperature processing of the second example, when the control unit 90 determines that the temperature Ta of the first motor 81 has fallen below a third reference value TH3 (third value) that is lower than the second reference value TH2 (S324: No), it controls the first motor 81 to transport the first member 101 until the media sensor 64 detects the first member 101 (S326). The same applies when the control unit 90 executes the high-temperature processing of the third example. In this way, when the temperature Ta of the first motor 81 falls below the third reference value TH3, the control unit 90 controls the first transport roller 41 to transport the first member 101 until the media sensor 64 detects the first member 101. This transports the first member 101 to the desired position, and the laminating apparatus 1 can be easily restarted after the first motor 81 has been stopped due to heat generation.

[0177] [Fourth embodiment] The control unit 90 of the laminating device 1 according to the fourth embodiment executes the laminating process shown in FIG. 5, and executes the high temperature process shown in FIG. 14(C) upon determining that the temperature Ta of the first motor 81 has reached the second reference value TH2.

[0178] As shown in Figures 14(A) and 14(B), the laminating apparatus 1 according to the fourth embodiment further includes an elevating mechanism 65 that moves the contact member 61 of the tension generating unit 60 in the up-down direction 7. The elevating mechanism 65 allows the contact member 61 to move in the up-down direction 7 between a first position where tension is applied to the first member 101 disposed between the first conveyor roller 41 and the intermediate roller 44, and a second position where tension is not applied to the first member 101 disposed between the first conveyor roller 41 and the intermediate roller 44. In an initial state, the contact member 61 is located at the first position.

[0179] 14(C), the control unit 90 first stops the intermittent conveyance of the first member 101 (S411). Next, the control unit 90 moves the abutting member 61 to a second position where it does not abut against the first member 101 (S412). In S412, the control unit 90 controls the lifting mechanism 65 to move the abutting member 61 from the first position where it applies tension to the first member 101 disposed across the first conveyance roller 41 and the intermediate roller 44, to the second position where it does not apply tension to the first member 101.

[0180] Next, the control unit 90 determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S413). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S413: Yes), the control unit 90 proceeds to S413, and if the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S413: No), the control unit 90 proceeds to S414.

[0181] In the latter case, the control unit 90 moves the abutting member 61 to a first position where it abuts against the first member 101 (S415). In S415, the control unit 90 controls the lifting mechanism 65 to move the abutting member 61 from the second position where no tension is applied to the first member 101 disposed across the first conveyance roller 41 and the intermediate roller 44, to the first position where tension is applied to the first member 101. Next, the control unit 90 resumes the intermittent conveyance of the first member 101 (S415).

[0182] In the fourth embodiment, the first member 101 is an example of a member. The first conveying roller 41 is an example of a first conveying mechanism. The intermediate roller 44 is an example of a second conveying mechanism. The tension generating unit 60 is an example of a tension applying unit. The second reference value TH2 is an example of a first value. S412 is an example of tension release control.

[0183] [Operation and effect of the fourth embodiment] As described above, the laminating apparatus 1 according to the fourth embodiment includes the first conveyor roller 41 (first conveyor mechanism), the first motor 81 (first conveyor mechanism), a tension generating unit 60 (tension applying unit) including the contact member 61 (moving member), and the control unit 90. In response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2 (first value) (S17: Yes), the control unit 90 performs tension release control to move the contact member 61 from the first position to the second position during the high-temperature treatment shown in FIG. 13(C) (S412).

[0184] Therefore, according to the laminating device 1 of the fourth embodiment, when the temperature Ta of the first motor 81 reaches the second reference value TH2, the abutment member 61 is moved from the first position to the second position, thereby releasing the tension applied to the first member 101 held between the first conveying roller 41 and the intermediate roller 44, and the conveying device that was stopped after the first motor 81 or the second motor 82 was stopped due to heat generation can be easily restarted.

[0185] The laminating apparatus 1 further includes a recording unit 30, and the control unit 90 performs intermittent conveyance control to alternately perform a conveying operation and a recording operation (S14, S15). When the control unit 90 determines that the temperature Ta of the first motor 81 has reached a second reference value TH2 during the intermittent conveyance control (S17: Yes), the control unit 90 stops the intermittent conveyance control (S411) and performs tension release control (S412) in the high-temperature process shown in Fig. 13(C) , and when the control unit 90 determines that the temperature Ta of the first motor 81 has fallen below a third reference value TH3 (third value) that is lower than the second reference value TH (S413: No), the control unit 90 resumes the intermittent conveyance control (S415).

[0186] Therefore, when the temperature Ta of the first motor 81 reaches the second reference value TH2 while the intermittent conveying control is being executed, the intermittent conveying control is stopped, the tension applied to the first member 101 held between the first conveying roller 41 and the intermediate roller 44 is released, and when the temperature Ta drops below the third reference value TH3, the intermittent conveying control is resumed, thereby making it possible to easily restart the laminating device 1 that was stopped after the first motor 81 or the second motor 82 was stopped due to heat generation.

[0187] [Fifth embodiment] The control unit 90 of the laminating device 1 according to the fifth embodiment executes the laminating process shown in FIG. 9, and executes the high temperature process shown in FIG. 15 in response to determining that the temperature Ta of the first motor 81 has reached the second reference value TH2.

[0188] 15 , first, the control unit 90 drives the first motor 81 so that the first member 101 between the first conveyor roller 41 and the intermediate roller 44 becomes slack (S511). Next, the control unit 90 drives the second motor 82 so that the first member 101 between the first roll 111 and the intermediate roller 44 becomes slack (S512). Next, the control unit 90 drives the third motor 83 so that the second member 102 between the second roll 112 and the laminating roller 50 becomes slack (S513).

[0189] In S511, the control unit 90, for example, drives the first motor 81 in the reverse direction to rotate the first conveyor roller 41 in the reverse direction, thereby sagging the first member 101 between the first conveyor roller 41 and the intermediate roller 44. In S512, the control unit 90, for example, drives the second motor 82 in the reverse direction to rotate the first roll 111 in a direction to pull out the first member 101, thereby sagging the first member 101 between the first roll 111 and the intermediate roller 44. In S513, the control unit 90, for example, drives the third motor 83 in the reverse direction to rotate the second roll 112 in a direction to pull out the second member 102, thereby sagging the second member 102 between the second roll 112 and the laminating roller 50.

[0190] Next, the control unit 90 determines whether the temperature Ta of the first motor 81 is equal to or greater than the third reference value TH3 (S514). If the control unit 90 determines that the temperature Ta is equal to or greater than the third reference value TH3 (S514: Yes), the control unit 90 proceeds to S514, and if the control unit 90 determines that the temperature Ta is less than the third reference value TH3 (S514: No), the control unit 90 proceeds to S515.

[0191] Next, the control unit 90 drives the first to third motors 81 to 83 so as to restore slack in the first member 101 between the first conveying roller 41 and the intermediate roller 44, the first member 101 between the first roll 111 and the intermediate roller 44, and the second member 102 between the second roll 112 and the laminating roller 50 (S515). Next, the control unit 90 ends the high-temperature treatment shown in FIG.

[0192] In the fifth embodiment, the first holder 21 is an example of a first support portion. The second holder 22 is an example of a second support portion. The first conveying roller 41 is an example of a first conveying mechanism. The first motor 81 is an example of a first driving portion. The intermediate roller 44 is an example of a second conveying mechanism. The second motor 82 is an example of a second driving portion. The first cutting portion 68 is an example of a cutting portion. The third motor 83 is an example of a third driving portion. The second reference value TH2 is an example of a first value.

[0193] S511 is an example of first tension release control in which the first drive unit is driven so that the first tension is not applied to the first member 101 between the second conveyance mechanism and the first conveyance mechanism. S512 is an example of second tension release control in which the second drive unit is driven so that the second tension is not applied to the first member 101 between the first roll 111 and the first conveyance mechanism. S513 is an example of third tension release control in which the third drive unit is driven so that the third tension is not applied to the second member 102 between the second roll 112 and the laminating roller 50.

[0194] [Effects of the Fifth Embodiment] As described above, the laminating apparatus 1 according to the fifth embodiment has the same elements as the laminating apparatus 1 according to the second embodiment. Like the control unit 90 of the laminating apparatus 1 according to the second embodiment, the control unit 90 performs intermittent conveyance control (S14, S15), performs second tension application control and third tension application control while performing intermittent conveyance control, and, in response to determining that the temperature of at least one of the first to third motors 81 to 83 has reached the second reference value TH2 (first value) (S52: Yes), performs first tension release control (S511), second tension release control (S512), and third tension release control (S513).

[0195] Therefore, according to the laminating device 1 of the fifth embodiment, when the temperature of at least one of the first to third motors 81 to 83 reaches the second reference value TH2, the first to third tension release controls are performed to release the tension applied to the first member 101 between the intermediate roller 44 and the first conveying roller 41, the tension applied to the first member 101 between the first roll 111 and the intermediate roller 44, and the tension applied to the second member 102 between the second roll 112 and the laminating roller 50, and the laminating device 1 that was stopped after the first to third motors 81 to 83 were stopped due to heat generation can be easily restarted.

[0196] [Variations] Various modifications can be made to the laminating apparatus 1 according to the first to fifth embodiments. In the laminating apparatus according to the modifications, the laminating roller 50 may include a single laminating roller. By disposing the single laminating roller at a suitable position within the housing 11, the first member 101, which has been drawn from the first roll 111 and on which an image has been recorded by the recording unit 30, and the second member 102, which has been drawn from the second roll 112, can be bonded together by the single laminating roller. Furthermore, the laminating roller 50 of the laminating apparatus according to the modifications does not necessarily have to include a rotating roller. For example, the laminating roller may include two plate-like members arranged at a predetermined interval in the vertical direction 7. In this case, a gripping member located downstream in the conveyance direction may grip the first member 101 and the second member 102 and pull them in a predetermined direction.

[0197] The laminating device according to the modified example does not need to include the second cutting unit 69. In this case, the member formed by bonding the first member 101 and the second member 102 together is discharged from the discharge port 14 in an uncut state. The user cuts the discharged member outside the laminating device, for example, using scissors.

[0198] Although the recording unit 30 of the laminating device 1 has a recording head 32 that ejects ink and records images using a so-called serial inkjet method, the configuration of the recording unit 30 is not limited to this.
