Description

TECHNICAL FIELD

[0001] The present application relates to a conveying system, a conveying device, a recording system, and a control method of a conveying device. BACKGROUND

[0002] In Patent Literature 1, a recording device is disclosed, which is provided with a conveying belt having an adhesive layer, a recording section that records a medium adhered to the adhesive layer, and a heating section that heats the conveying belt. In this case, it is known that the adhesiveness of the medium to the adhesive layer is improved by heating the adhesive layer with the heating section. Therefore, it is important to control the heating section with high precision in order to improve the adhesiveness of the medium.

[0003] Further, in Patent Literature 2, a recording device is described, which is provided with a conveying belt having an adhesive layer, a recording section that records a medium adhered to the adhesive layer, and a detection section that detects the adhesiveness of the adhesive layer. The detection section rotates in conjunction with the circumferential rotation of the conveying belt while being in contact with the adhesive layer when the conveying belt is circumferentially rotated. In this recording device, when the adhesiveness of the adhesive layer decreases and the rotation of the detection section stops, the replacement timing of the adhesive layer is notified.

[0004] However, the adhesiveness of the adhesive layer decreases due to various reasons such as the attachment of ink or medium fibers on the surface of the adhesive layer, or the deterioration of the adhesive layer over time, and thus does not necessarily depend only on the heating temperature. That is, even if the heating temperature is properly managed, the adhesiveness of the adhesive layer changes due to other reasons such as foreign matter attached to the surface thereof or the deterioration of the adhesive layer itself. Therefore, there is a problem that the medium can not be properly adhered in a case where the actual adhesiveness of the adhesive layer is maintained as it is and decreases.

[0005] Further, although the detection section described in Patent Literature 2 detects the adhesiveness of the adhesive layer and notifies the replacement timing, the adhesiveness of the adhesive layer of the conveying belt cannot be controlled to be appropriate during the operation of the medium conveying device.

[0022] Hereinafter, with respect to one embodiment of a recording system, the description will be given while referring to the accompanying drawings.

[0023] As shown in Figure 1 , the recording system 10 is provided with a recording device 11 and a peeling device 13. The recording system 10 of the present embodiment is provided with an informing device 14, a holding device 15, a tension adjusting device 16, and a terminal device 40 capable of communicating with the recording device 11.

[0024] The notification device 14 of the present embodiment has a display portion 17 and an input portion 18.

[0025] The display portion 17 displays information. The display portion 17 is, for example, a liquid crystal display. The notification device 14 displays various kinds of information by the display portion 17, thereby notifying the user. The notification device 14 can also notify the operation status of the conveyance device 12.

[0026] The input portion 18 is a structure that inputs an instruction. Therefore, the user inputs an instruction to the input portion 18 in a case where the recording system 10 is operated. The instruction input to the input portion 18 is input to the recording device 11 by the notification device 14.

[0027] The input portion 18 is, for example, a touch panel. Therefore, in the present embodiment, the display portion 17 and the input portion 18 are integrally constituted. The input portion 18 can be, for example, a mouse, a keyboard, or the like.

[0028] The recording device 11 is, for example, an inkjet printer that records an image such as a letter or a photograph by ejecting ink, which is an example of a liquid, to a medium 99 such as cloth, paper, or the like.

[0029] The recording device 11 has a recording portion 22, the conveyance device 12, and a control portion 20. The control portion 20 controls the recording device 11 as a whole, for example. The control portion 20 is configured to be able to communicate with the peeling device 13, the notification device 14, the holding device 15, the tension adjusting device 16, and the terminal device 40. The control portion 20 can also control the peeling device 13, the notification device 14, the holding device 15, the tension adjusting device 16, and the terminal device 40.

[0030] The conveyance device 12 has a conveyance belt 23 that conveys the medium 99 that the recording portion 22 is configured to record (refer to Figure 2 ). The conveyance belt 23 has an adhesive layer 32 (refer to Figure 2 ) and conveys the medium 99 that is attached to the adhesive layer 32. The conveyance belt 23 of the present embodiment is a heat-sensitive type adhesive tape that has an adhesive that exhibits adhesiveness when heated as the adhesive layer 32 on the surface. The adhesive is also referred to as glue in the present specification. The conveyance device 12 has a heating portion 19 that is able to heat the adhesive layer and a driving portion 25 that drives the conveyance belt 23. The conveyance device 12 has a temperature detecting portion 30 that is able to detect the temperature of the conveyance belt 23. The temperature detecting portion 30 is, for example, a thermistor or a non-contact type temperature sensor.

[0031] The terminal device 40 has a communication section 41 for communicating with the recording device 11, and a storage section 42 in which software for editing image data transmitted to the recording device 11 is stored. The communication section 41 is capable of transmitting task data or various data related to image data to the recording device 11 via a wired or wireless network. The storage section 42 has a non-volatile storage medium such as an SSD (Solid State Disk) or an HDD (Hard Disk Drive), and is capable of saving image data or various data. In addition, the terminal device 40 is electrically connected to the notification device 14, and is capable of performing editing of image data or the like via the notification device 14.

[0032] In addition, the notification device 14 can be provided in the terminal device 40 or can be independent of the terminal device 40. In the case where the notification device 14 is independent of the terminal device 40, the notification device 14 is capable of information communication with the terminal device 40 using a communication cable or the like.

[0033] The control section 20 can be constituted as a circuit including one or more processors that execute various processes according to a computer program, one or more dedicated hardware circuits that execute at least a part of the various processes, or a combination thereof. The processor includes a CPU and a memory such as a RAM and a ROM, and the memory stores program codes or instructions that cause the CPU to execute processes. The memory, that is, the computer-readable medium includes all readable media that can be accessed by a general-purpose or a special-purpose computer.

[0034] The control section 20 includes a detection section 21. The detection section 21 is, for example, a motor driver. In this case, in the control section 20, the motor driver and the processor can be arranged on the same chip or on different chips.

[0035] The detection section 21 is capable of detecting a load of the driving section 25. The detection section 21 of the present embodiment detects a load of the driving section 25 in a case where the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. The control section 20 of the present embodiment controls a current flowing in the driving section 25 by outputting a current command value to the motor driver, thereby performing speed control of the conveyance belt 23. Therefore, the motor driver is capable of detecting a current value flowing in the driving section 25. Since the driving section 25 is controlled in such a manner that driving is performed at a target speed, if a load when the conveyance belt 23 is driven becomes large, the driving current increases. The current of the driving section 25 varies depending on the load of the conveyance belt 23.

[0036] The load of the medium 99 on the conveyance belt 23 when the medium 99 is peeled from the conveyance belt 23 depends on the adhesion of the adhesion layer 32. The greater the adhesion of the adhesion layer 32, the greater the load detected by the detection section 21. The detection section 21 detects the load of the drive section 25 as a load current flowing in the drive section 25. The control section 20 controls the heating section 19 on the basis of the detection result of the detection section 21. That is, the control section 20 performs a heating temperature control process of controlling the heating temperature of the heating section 19 on the basis of a detection value obtained by detecting the load of the drive section 25. Details of the heating temperature control process will be described later.

[0037] Next, the structure of the recording system 10 will be described with reference to Figure 2 Fig. 1. As shown in Fig. 1, the recording apparatus 11 is provided with a recording section 22 and a conveyance apparatus 12. The conveyance apparatus 12 has a conveyance belt 23, a drive roller 24, a drive section 25, and a driven roller 26. The conveyance apparatus 12 of the present embodiment has a heating section 19, a pressing section 27, a cleaning section 28, and a drying section 29. Figure 2

[0038] The recording section 22, for example, ejects a liquid toward the medium 99. Thereby, the recording section 22 records on the medium 99. The recording section 22 is, for example, a head. The recording section 22 can be a serial head that scans with respect to the medium 99, or a line head that extends across a range substantially the same as the width of the medium 99.

[0039] In addition, the recording section 22 is not limited to the inkjet system, but can be an electrophotographic system in which an image or the like is fixed on the medium 99 by various photosensitive units after a solid toner is applied.

[0040] The recording apparatus 11 has the conveyance apparatus 12. The conveyance apparatus 12 includes the conveyance belt 23, the drive roller 24, and the driven roller 26. The conveyance belt 23 has a base material 31 and an adhesion layer 32.

[0041] The base material 31 is provided in a jointless shape. The base material 31 has a first face 33 and a second face 34 that is a face opposite to the first face 33. The first face 33 is a face that becomes an outer peripheral face in the base material 31. The second face 34 is a face that becomes an inner peripheral face in the base material 31.

[0042] ​An adhesive layer 32 is disposed on the first surface 33. The adhesive layer 32 is adhesive. The adhesive layer 32 is formed using an adhesive with adhesive properties. The adhesive layer 32 is formed by applying an adhesive to the first surface 33. The adhesive layer 32 is formed in a manner that spans the entire circumference of the first surface 33. The adhesive force of the adhesive layer 32 decreases with use of the recording device 11, the passage of time, etc. In this embodiment, when the layer on which the medium 99 is adhered is designated as the surface layer, an adhesive with the characteristic that the higher the temperature of the surface layer of the adhesive layer 32, the greater the adhesive force of the adhesive layer 32. Alternatively, an adhesive with the characteristic that the higher the temperature of the surface layer of the adhesive layer 32, the lower the adhesive force of the adhesive layer 32 can also be used.

[0043] The adhesive layer 32 is used to adhere the medium 99. Specifically, the conveyor belt 23 transports the medium 99 adhered to the adhesive layer 32. The medium 99 is recorded by the recording unit 22 midway through its transport by the conveyor belt 23. Therefore, the recording unit 22 is located opposite the first surface 33 relative to the substrate 31. In this embodiment, the recording unit 22 is located above the conveying device 12.

[0044] The conveyor belt 23 is designed to be seamless. In this embodiment, the conveyor belt 23 is wound around the drive roller 24 and the driven roller 26. Thus, in the substrate 31, the second surface 34 contacts the drive roller 24 and the driven roller 26. The conveyor belt 23 conveys the medium 99 by rotating circumferentially. The conveyor belt 23 rotates circumferentially around the drive roller 24 and the driven roller 26. In other words, the conveyor belt 23 rotates around the center point of an imaginary straight line connecting the rotation center of the drive roller 24 to the rotation center of the driven roller 26.

[0045] The drive roller 24 is configured to be rotatable. The drive roller 24 is connected to the drive unit 25. The drive unit 25 is, for example, a motor. When the drive unit 25 drives the drive roller 24, the drive roller 24 rotates. When the drive roller 24 rotates, the conveyor belt 23 rotates circumferentially. By employing this method, the drive unit 25 transmits driving force to the drive roller 24, thereby driving the conveyor belt 23. In this embodiment, the drive unit 25 can cause the drive roller 24 to rotate in both a first direction and a second direction, which is opposite to the first direction. That is, the conveyor belt 23 can rotate circumferentially in both the direction of the conveying medium 99 and the reverse conveying direction, which is opposite to the conveying direction.

[0046] The drive unit 25 includes an encoder 35. The encoder 35 is a structure used to detect the rotation amount, speed, etc. of the drive roller 24. The encoder 35 enables the drive roller 24 to rotate with high precision.

[0047] The driven roller 26 is rotatably provided. The driven roller 26 is rotated in conjunction with the rotation of the conveyance belt 23. That is, the driven roller 26 is rotated in conjunction with the rotation of the drive roller 24.

[0048] The pressing portion 27 is located outside the conveyance device 12. Thus, the pressing portion 27 is located at a position opposite to the first surface 33 with respect to the base material 31. The pressing portion 27 of the present embodiment is located upwardly compared to the conveyance device 12.

[0049] The pressing portion 27 presses the medium 99 against the conveyance belt 23. Thus, the medium 99 is attached to the adhesive layer 32. The pressing portion 27 of the present embodiment presses the medium 99 downwardly toward the conveyance belt 23. The pressing portion 27 rotates in conjunction with the conveyance belt 23, thereby sequentially attaching the medium 99 to the adhesive layer 32.

[0050] The pressing portion 27 is, for example, a rod that does not rotate. The pressing portion 27 can also be a roller that can rotate. The pressing portion 27, for example, reciprocally moves by a predetermined distance on the circumferential surface of the conveyance belt 23, thereby effectively attaching the medium 99 to the adhesive layer 32.

[0051] The cleaning portion 28 is located outside the conveyance belt 23. Thus, the cleaning portion 28 is located at a position opposite to the first surface 33 with respect to the base material 31. The cleaning portion 28 of the present embodiment is located downwardly compared to the conveyance belt 23.

[0052] The cleaning portion 28 cleans the adhesive layer 32 by contacting the adhesive layer 32. The cleaning portion 28 of the present embodiment contacts the conveyance belt 23 from below. The cleaning portion 28, for example, includes a brush that contacts the adhesive layer 32. The cleaning portion 28 rotates in conjunction with the conveyance belt 23, thereby sequentially cleaning the adhesive layer 32.

[0053] In the recording device 11, liquid sometimes adheres to the adhesive layer 32 in conjunction with the recording portion 22 recording the medium 99. In order to remove the liquid adhering to the adhesive layer 32, the cleaning portion 28 cleans the adhesive layer 32.

[0054] The cleaning portion 28 of the present embodiment cleans the adhesive layer 32 using a cleaning liquid. The cleaning portion 28, for example, cleans the adhesive layer 32 by contacting the adhesive layer 32 with a brush wetted with the cleaning liquid. Thus, the liquid adhering to the adhesive layer 32 can be effectively removed. In this case, the conveyance belt 23 is wetted with the cleaning liquid when the cleaning portion 28 cleans the adhesive layer 32. The cleaning liquid is, for example, water.

[0055] The drying section 29 is located outside the conveyance belt 23. Therefore, the drying section 29 is located opposite the first face 33 with respect to the base material 31. The drying section 29 of the present embodiment is located lower than the conveyance belt 23.

[0056] The drying section 29 dries the adhesive layer 32 that has been wetted by the cleaning liquid. The drying section 29 dries the adhesive layer 32, for example, by blowing hot air onto the conveyance belt 23. The drying section 29 of the present embodiment blows hot air onto the conveyance belt 23 from below. The drying section 29 rotates around the circumference of the conveyance belt 23, thereby sequentially drying the adhesive layer 32 that has been wetted by the cleaning liquid.

[0057] The heating section 19 is located outside the conveyance belt 23. Therefore, the heating section 19 is located opposite the first face 33 with respect to the base material 31. The heating section 19 of the present embodiment is located lower than the conveyance belt 23 or from the side of the driven roller 26. The heating section 19 is located opposite the first face 33 of a portion that is located upstream of the pressing section 27 and downstream of the drying section 29 in the direction of rotation of the conveyance belt 23 when recording the medium 99.

[0058] The heating section 19 heats the adhesive layer 32. The heating section 19 has a heater 19H, for example. The heating section 19 can also have a hot air blower that heats by hot air instead of the heater 19H. In general, the heating section 19 can be any one of a radiation type, a conduction type, a hot air type (convection type), and a combination thereof, as long as it can heat the medium 99.

[0059] The reason why the heating section 19 is arranged at the above-described position close to the pressing section 27 is as follows. This is to press the medium 99 against the adhesive layer 32 while the adhesion of the adhesive layer 32 that has been heated is high, and further to ensure the adhesion, by shortening the distance from the pressing section 27 to the heating position of the heating section 19 toward the upstream side in the belt rotation direction to a predetermined distance or less.

[0060] In addition, the conveyance device 12 is provided with a temperature detection section 30 that can detect the temperature of the conveyance belt 23. The temperature detection section 30 can be a device that indirectly detects the temperature of the conveyance belt 23 by detecting the temperature of the heating section 19, or a device that directly detects the temperature of the conveyance belt 23 in a non-contact manner. The temperature detection section 30 can also be a device that detects the temperature of a metal-made radiating member such as an aluminum plate that is heated by the heat of the heater 19H that constitutes the heating section 19 and heats the conveyance belt 23 by radiating the heat. In Figure 2 In the example shown, the conveyance device 12 is also provided with a second temperature detection section 38 that detects the temperature of the conveyance belt 23 in a non-contact manner.

[0061] The temperature detecting section 30 is used for control of the heating temperature of the heating section 19. The second temperature detecting section 38 is used for detection of abnormal overheating of the conveyance belt 23. In addition, the second temperature detecting section 38 can be used for control of the heating temperature of the heating section 19, or a structure can be adopted in which one temperature detecting section is provided which serves both for heating control and for overheating detection.

[0062] Next, the series of actions of the recording device 11 will be described while focusing on a specific region on the circumferential surface of the conveyance belt 23.

[0063] First, the pressing section 27 presses the medium 99 against the specific region on the circumferential surface of the conveyance belt 23. Next, the recording section 22 records the medium 99 which is attached to the specific region. Next, the medium 99 which is attached to the specific region is peeled from the conveyance belt 23 by the peeling device 13. Next, the cleaning section 28 cleans the specific region. Next, the drying section 29 dries the specific region. Next, the heating section 19 heats the specific region. The adhesion of the adhesion layer 32 in the specific region is increased by the heating. Next, the pressing section 27 presses the medium 99 again against the specific region. In this way, the image is recorded on the medium 99 in order by the circumferential rotation of the conveyance belt 23.

[0064] Next, the holding device 15, the tension adjusting device 16, and the peeling device 13 will be described.

[0065] The holding device 15 holds the roll body in which the medium 99 is wound. The holding device 15 holds the roll body in a rotatable manner. The roll body held by the holding device 15 is a first roll body Rl in which the medium 99 before recording is wound. In the present embodiment, the medium 99 is unwound from the first roll body Rl held on the holding device 15 by the conveyance belt 23 being driven. The medium 99 which is unwound is conveyed from the holding device 15 toward the recording device 11.

[0066] The tension adjusting device 16 has, for example, a contact member 36 and an elastic member 37. The contact member 36 contacts the medium 99 between the holding device 15 and the recording device 11. The contact member 36 of the present embodiment contacts the face on which the recording section 22 records with respect to the medium 99. The contact member 36 can be, for example, a non-rotating rod which is cylindrical, or a roller which can rotate.

[0067] The elastic member 37 has elasticity. The elastic member 37 is installed on the contact member 36. The elastic member 37 is, for example, a spring. The elastic member 37 is stretched and contracted in accordance with the magnitude of the tension applied to the medium 99 between the holding device 15 and the recording device 11. That is, in the case where the tension applied to the medium 99 is large, the elastic member 37 is contracted. In the case where the tension applied to the medium 99 is small, the elastic member 37 is stretched. By adopting such a configuration, the tension adjusting device 16 adjusts the tension of the medium 99 between the holding device 15 and the recording device 11 in such a manner that the tension becomes substantially constant.

[0068] The peeling device 13 holds the roll body in which the medium 99 is wound. The peeling device 13 holds the roll body in a rotatable manner. The roll body held by the peeling device 13 is a second roll body R2 in which the medium 99 after the recording device 11 is wound.

[0069] The peeling device 13 can also have a dryer 45 between the conveyance belt 23 and the roll body. The dryer 45 has a conveyance section 46 that conveys the medium 99, and a dryer 47 that dries the medium 99 conveyed by the conveyance section 46. The dryer 47 can also be provided on both sides of the conveyance path of the medium 99, for example, and dries the medium 99 from both sides. The dryer 47 can be either a heater type or a hot air type. The peeling device 13 has a sensor 48 that can detect the medium 99. The peeling device 13 is driven in the direction in which the medium 99 is wound by a predetermined amount when the sensor 48 detects the medium 99.

[0070] Thus, in the recording system 10, the peeling device 13 winds the medium 99 from the recording device 11. That is, the peeling device 13 recovers the medium 99. The peeling device 13 is driven by a driving source such as a motor not shown, and winds the medium 99 from the recording device 11 at a predetermined torque.

[0071] The peeling device 13 peels the medium 99 from the conveyance belt 23. The peeling device 13 of the present embodiment peels the medium 99 from the conveyance belt 23 by causing the second roller body R2 to rotate. Specifically, the peeling device 13 peels the medium 99 at the peeling position P2 on the driving roller 24 in the circumferential surface of the conveyance belt 23. Since a predetermined tension is applied to the portion of the medium 99, i.e., the medium 99B, from the peeling position P2 to the peeling device 13, the medium 99B is substantially free from slack. Here, the portion of the medium 99 that is pasted to the adhesive layer 32 at a position upstream of the peeling position P2 in the circumferential rotation direction of the conveyance belt 23 is referred to as the medium 99A. At this time, the angle that the medium 99A makes with the medium 99B, i.e., the peeling angle θ, at the vicinity of the peeling position P2 is less than 90 degrees. In the present embodiment, the greater the adhesive force of the adhesive layer 32, the smaller the peeling angle θ. That is, the peeling position P2 with respect to the driving roller 24 varies depending on the adhesive force.

[0072] On the medium 99B, which is a portion of the medium 99, a tension Te based on the adhesive force that acts between the adhesive layer 32 and the medium 99 is applied. The tension Te acts from the peeling position P2 toward the peeling device 13. Here, since the peeling angle θ is less than 90 degrees, the component TA along the medium 99A of the component of the tension Te is oriented close to the reverse conveyance direction. The component TA along the medium 99A can be expressed as T x cos θ. At this time, when the medium 99 is peeled from the conveyance belt 23 by the peeling device 13 without causing slippage between the driving roller 24 and the conveyance belt 23, a moment based on the component TA along the medium 99A will act in a manner that resists the rotational moment of the driving roller 24. Therefore, the peeling of the medium 99 from the conveyance belt 23 by the peeling device 13 becomes a resistance to the circumferential rotation of the conveyance belt 23. That is, when the peeling device 13 peels the medium 99 from the conveyance belt 23, a load will be generated in the driving section 25. When a load is generated in the driving section 25, a load current corresponding to the magnitude of the load will flow to the driving section 25.

[0073] The greater the adhesion of the adhesive layer 32, the greater the resistance generated in the driving section 25 due to the peeling of the medium 99 from the conveyance belt 23. Thus, the greater the adhesion of the adhesive layer 32, the greater the load current flowing to the driving section 25 in order to output the target conveyance speed of the conveyance belt 23. Conversely, when the adhesion of the adhesive layer 32 is small, the load current flowing to the driving section 25 in order to output the target conveyance speed of the conveyance belt 23 becomes small. That is, in the case where the adhesion of the adhesive layer 32 is large, the load current flowing to the driving section 25 becomes large compared to the case where the adhesion of the adhesive layer 32 is small. In this way, when the medium 99 is peeled from the conveyance belt 23, the load current corresponding to the magnitude of the adhesion flows to the driving section 25. That is, the so-called load current refers to the current supplied to the driving section 25 in order to output the target conveyance speed of the conveyance belt 23 in the case where the medium 99 is peeled from the adhesive layer 32.

[0074] Contents of heating temperature control

[0075] Next, the heating temperature control performed by the control section 20 will be described with reference to FIGS. 10 to 12. Figure 3 Figure 4 The control section 20 controls the heating section 19 based on the detection result of the detection section 21. The detection section 21 detects the load of the driving section 25 in the case where the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. Thus, the control section 20 controls the heating section 19 based on the load of the driving section 25 detected by the detection section 21 when the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. Specifically, the control section 20 controls the heating section 19 based on the load current flowing through the driving section 25 according to the load of the medium 99 borne by the conveyance belt 23 when the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. Here, the greater the adhesion of the adhesive layer 32, the greater the value of the load current, and the smaller the adhesion of the adhesive layer 32, the smaller the value. Further, even if the adhesion is the same, the adhesion force differs if the medium types are different. Also, in order to prevent the positional deviation of the medium on the conveyance belt 23, the adhesion force needs to be above a threshold regardless of the medium type. Thus, the control section 20 controls the heating section 19 to a temperature at which the desired adhesion force can be obtained based on the load current detected by the detection section 21.

[0076] The control section 20 stores, in a storage section such as a memory, reference data indicating the relationship between the detected load (in the present example, the load current value as the value of the load current) and the adhesion for each medium type. The reference data is created based on measured data obtained by measuring the relationship between the adhesion of the adhesive layer 32 and the load current value through experiments in which the medium type is changed, or simulation data obtained by simulating the relationship. ​

[0077] The control unit 20 infers the current adhesive force based on the load current value and performs feedback control on the heating temperature of the heating unit 19 in a manner that makes the inferred current adhesive force close to the target adhesive force. This feedback control can be implemented by setting the adhesive force value obtained by converting the load current value as the control variable, or by directly using the load current value detected by the detection unit 21 as the control variable.

[0078] Here, as Figure 2 As shown, the position where the conveyor belt 23 is heated by the heating unit 19 is designated as the heating position P1, and the position where the medium 99 is peeled off from the conveyor belt 23 is designated as the peeling position P2. However, the adhesive force is determined by the bonding force and the type of medium. Therefore, for the load current detected by the detection unit 21, if the type of medium is the same, it becomes a value corresponding to the adhesive force. The load detected at the peeling position P2, where the medium 99 is peeled off from the conveyor belt 23, depends on the heating temperature at the heating position P1 before a predetermined time. When the distance along the outer circumference of the conveyor belt 23 from the heating position P1 to the peeling position P2 is set as D, and the moving speed of the conveyor belt 23 is set as V, the time T1 required until the position on the conveyor belt 23 moves from the heating position P1 to the peeling position P2 can be expressed as T1 = D / V. The adhesive force detected at the peeling position P2 is the result of heating at the heating temperature before the required time T1. Therefore, the control unit 20 takes into account the deviation corresponding to the distance D and controls the heating temperature when the position on the conveyor belt 23 located at the peeling position P2 reaches the heating position P1 based on the load value detected at the peeling position P2.

[0079] Furthermore, the adhesive force of the medium 99 is not necessarily constant during one revolution of the conveyor belt 23. It may decrease at locations where foreign matter such as ink or medium fibers adheres to the adhesive layer 32, or at locations where the adhesive layer 32 has deteriorated. Therefore, in this embodiment, the adhesive force (load) for one revolution of the conveyor belt 23 is measured to obtain historical information related to the adhesive force for one revolution of the belt. Moreover, even when the adhesive force decreases due to the adhesion of foreign matter or the deterioration of the adhesive, the control unit 20 controls the heating temperature of the heating unit 19 based on this load history information in order to obtain the required adhesive force.

[0080] Figure 3 This represents the load history information LP for one cycle of the load. Figure 3In the graph of the one-loop amount of the belt, the horizontal axis indicates the rotation position of the belt of one loop amount, and the vertical axis indicates the temperature T and the load L. The rotation position of the belt is indicated, for example, as a position on the conveyor belt 23 corresponding to the peeling position P2 at the start of measurement of the load, as a starting point, and a position on the conveyor belt 23 passing through the peeling position P2 during one rotation (one loop) of the conveyor belt 23 from the start of measurement of the load. In Figure 3 In the graph, the temperature history information HT and the load history information LP are shown. When the temperature of the conveyor belt 23 reaches the target temperature T0, the control section 20 starts measurement of the load history information LP. The control section 20 acquires the load history information LP of one loop amount of the belt by detecting the load at the peeling position P2 from which the medium 99 is peeled from the conveyor belt 23 in the form of one loop amount of the belt at the target temperature T0.

[0081] As shown in Figure 3 , the load history information LP of one loop amount of the belt becomes information of a history in which the load varies during one loop of the belt due to the presence of a place in which the adhesion is reduced due to the attachment of foreign matter to the adhesive layer 32 or the deterioration of the adhesive. When the initial load history information LP of one loop amount of the belt is acquired, the control section 20 controls the heating section 19 in such a manner that the conveyor belt 23 becomes the target temperature T0 based on the detected temperature of the temperature detection section 30.

[0082] Figure 4 The control temperature control processing of the heating section 19 based on the load history information LP shown in Figure 3 will be described with reference to a graph. In the graph of Figure 4 , as in Figure 3 , the horizontal axis indicates the rotation position of the belt, and the vertical axis indicates the temperature T and the load L. The control section 20 controls the heating temperature of the heating section 19 in such a manner that the target load L0 corresponding to the target adhesion force is obtained based on the load history information LP before one loop amount of the belt. The control section 20 controls the heating temperature of the heating section 19 based on the load history information LP shown in Figure 3 in such a manner that the control temperature CT shown in the graph of Figure 4 is the target temperature. The control temperature CT is greater than the value of the temperature history information HT. Through the heating temperature control processing by the control section 20, the heating section 19 is controlled so that the adhesion force inferred from the load L detected at the peeling position P2 becomes the target adhesion force inferred from the target load L0. Specifically, the minimum value of the load history information LP in Figure 3 is controlled to be equal to or greater than the target load L0. In the graph of Figure 4The load history information LP for the next one-reel amount of the tape is acquired during the period in which one reel of the tape is subjected to the heating temperature control process. In this way, the load history information LP for one-reel amount of the tape is acquired every time the tape 23 rotates once. Then, the control section 20 controls the heating temperature of the heating section 19 for the next one-reel of the tape based on the load history information LP acquired in the previous one-reel of the tape. Alternatively, the heating temperature control process can be performed for every reel thereafter based on the initial load history information LP for one-reel amount of the tape.

[0083] The above-described control is control in the case where the adhesive having the characteristic that the higher the temperature of the surface layer having the adhesive layer 32, the greater the adhesive force of the adhesive layer 32 is used. However, the manner of control is not limited to this. For example, in the case where the adhesive having the characteristic that the higher the temperature of the surface layer having the adhesive layer 32, the smaller the adhesive force of the adhesive layer 32 is used, the control temperature CT can be controlled in such a manner that the control temperature CT becomes smaller than the value of the temperature included in the temperature history information HT. Even in this case, the minimum value of the load history information LP in the period from the start of the recording operation to the start of the peeling operation is controlled to be equal to or greater than the target load L0. Figure 3

[0084] The control section 20 is provided with a preheating period (heating preparation period) in which the tape 23 is heated to the target temperature before shifting to the heating temperature control. In the preheating period, a preheating operation in which the tape 23 is heated in the state where the medium 99 is not present while the tape 23 is rotated around the circumference is performed. Then, when the tape 23 reaches the target temperature by the preheating operation, the medium 99 is placed on the tape 23, and a recording operation in which the recording section 22 records on the medium 99 is started to be performed. After reaching the target temperature T0, when a peeling operation in which the medium 99 is peeled from the tape 23 is started to be performed, since there is no load history information LP with respect to the initial one-reel amount of the tape in the control section 20, the load history information LP for one-reel amount of the tape is acquired under the condition where the target temperature T0 is maintained as it is. Figure 3

[0085] Display content of display section

[0086] As Figure 5 ​​As shown, the display unit 17 displays the setting screen 50. In this setting screen 50, setting data related to the type of fabric and adhesive, the target value of the adhesive strength, and the threshold value of the adhesive strength can be input. The setting screen 50 has an input field 51 for the type of fabric and an input field 52 for the type of adhesive. Even at the same heating temperature, the adhesive strength of the medium 99 relative to the adhesive layer 32 will change depending on the type of fabric and adhesive. Therefore, the control unit 20 can also recommend a target temperature corresponding to the information on the type of fabric and adhesive in the setting screen 50 during preheating.

[0087] In this embodiment, the control unit 20 controls the heating unit 19 such that the adhesive force of the medium 99 relative to the adhesive layer 32 is kept constant. Here, the load on the drive unit 25 includes a drive load for driving the conveyor belt 23, a peel load when the medium 99 is peeled off, and a contact load that bears contact with objects such as the pressing part 27 and the cleaning part 28. In this embodiment, the drive load and contact load are considered to be approximately constant based on a fixed conveyor belt speed. Furthermore, the greater the adhesive force of the medium 99, the greater the peel load. In other words, the peel load is a value corresponding to the adhesive force.

[0088] Therefore, the control unit 20 controls the heating unit 19 in a way that keeps the load on the drive unit 25 constant. Thus, the control unit 20 can control the heating unit 19 to keep the adhesive force constant.

[0089] In addition, Figure 5 The setup screen 50 shown includes an input field 53 for a target value and an input field 54 for a threshold value. In this embodiment, the target value is represented as a relative value (%) when the maximum load current is set to 100. Similarly, the threshold value is also represented as a relative value (%) when the maximum load current is set to 100. Here, the maximum load current is the initial value of the load current detected for the adhesive layer 32 when the adhesive force is detected.

[0090] The target value is the desired adhesive strength as requested by the user. If the target value is increased beyond the desired level, the heating temperature of the heating unit 19 will rise above the desired level, thus increasing the power consumption of the heating unit 19. Therefore, to save power consumption, the user can set a relative value for the adhesive strength. The threshold value is a value that specifies the replacement period of the adhesive layer 32. Since each user uses different types of fabric or adhesive, the required adhesive strength varies. Furthermore, even with the same adhesive strength, the required adhesive strength differs depending on the type of fabric (media). Therefore, a threshold value that specifies the replacement period of the adhesive layer 32 can be set for each user.

[0091] The adhesive force of the adhesive layer 32 decreases with the passage of time. Therefore, when the adhesion force is detected, the load current that is initially detected is the largest for the adhesive layer 32. The load current that is initially detected is referred to as the maximum load current. In addition, the minimum adhesion force at which the adhesive layer 32 should be replaced is set in advance by the control section 20 as the minimum adhesion force. The relative value of the minimum adhesion force with respect to the maximum adhesion force calculated from the maximum load current is set as the minimum value of the threshold value. In the input field 54, input of the threshold value can be performed in a range above the minimum threshold value.

[0092] In addition, in the input fields 53 and 54 of the setting screen 50, a configuration in which a set value of the adhesion force is input instead of a set value of the adhesion force can also be provided. Since the adhesion force is determined in accordance with the adhesion force and the type of cloth (medium type), the control section 20 can calculate the target adhesion force and the adhesion threshold value in accordance with the relative value of each adhesion force input into the input fields 53 and 54 with reference to reference data indicating the relationship between the adhesion force and the adhesion force (load current) for each type of cloth stored in the memory.

[0093] Further, in the setting screen 50, a confirmation button 55 and a cancel button 56 are displayed. The confirmation button 55 is a button for confirming the set values. When the confirmation button 55 is pressed in a state in which text and input values are input in all the items, the set values are confirmed. The cancel button 56 is a button for canceling the set values. When the cancel button 56 is pressed, the setting screen 50 is closed.

[0094] Effects of Embodiments

[0095] Next, the effects of the recording system 10, the recording device 11, and the conveying device 12 will be described.

[0096] Hereinafter, the effects of the recording system 10, the recording device 11, and the conveying device 12 will be described with reference to Figures 5-7 One example of the heating temperature control process performed by the control section 20 will be described. The control section 20 of the present embodiment performs the heating temperature control process for controlling the heating section 19 in parallel with the recording of the image. The user inputs various set values in the setting screen 50 displayed on the display section 17, for example, by operating the touch panel-type input section 18. The user selects and inputs information of the medium type and the type of glue from a list in the setting screen 50. Further, the user inputs a target value and a threshold value in the setting screen 50. The target value can be input by the input section 18. The threshold value can be input by the input section 18.

[0097] Hereinafter, the heating temperature control process performed by the control section 20 will be described.

[0098] In step Sll, the control section 20 implements a preheating operation. In detail, the control section 20 controls the heating section 19 based on the detection result of the temperature detection section 30 and in accordance with a predetermined temperature rising profile. In the present example, the current value of the heater 19H possessed by the heating section 19 is controlled. Thereby, the heater temperature (i.e., the detection temperature) is raised until the target temperature is reached. The target temperature is a temperature at which a proper adhesion is obtained. The target temperature is determined in accordance with the medium kind and the kind of glue. The control section 20 acquires the information of the medium kind and the kind of glue from the input information input to the setting screen 50.

[0099] In step S12, the control section 20 determines whether the target temperature has been reached. If the target temperature has been reached, the process proceeds to step S13, and if the target temperature has not been reached, the preheating operation of step Sll is continued.

[0100] In step S13, the control section 20 starts printing. The control section 20 starts the conveyance of the medium 99, and causes the recording section 22 to record an image based on the recording data with respect to the medium 99. At this time, since the heater temperature has reached the target temperature, the medium 99 is adhered to the tape with the required adhesion.

[0101] However, in a place where a liquid such as ink ejected by the recording section 22 is attached, a place where cloth fibers are attached, a place where the glue is peeled, and the like, the adhesion of the glue (adhesive) of the tape surface is reduced. Therefore, in one turn of the tape, the adhesion is uneven according to the position of the circumferential direction thereof. That is, in one turn of the tape, the adhesion is uneven according to the position of the circumferential direction thereof. In the present embodiment, the heater temperature control is implemented so as to reduce the unevenness of the adhesion in one turn of the tape.

[0102] In step S14, the control unit 20 detects the load of one revolution of the belt. The control unit 20 also detects the load of the drive unit 25. Specifically, the control unit 20 detects the load current of the drive unit 25 through the detection unit 21. That is, the control unit 20 sets the load current detected by the detection unit 21 as the load of the drive unit 25. In addition, after the peeling operation of peeling the recorded medium 99 off the conveyor belt 23 begins, the control unit 20 detects the load of the drive unit 25 during the period when the conveyor belt 23 completes one revolution. Whether the peeling operation of the medium 99 has started can be determined either by detecting the load of the drive unit 25 or by receiving an instruction from the input unit 18. For example, the user places the medium 99 on the belt and starts printing after the preheating operation is completed, or the medium 99 is conveyed by the conveyor belt 23 and the top of the medium 99 is wound around the core material in a non-printed state. Subsequently, the stripping action of stripping the medium 99 from the conveyor belt 23 is initiated by starting the winding action of the stripping device 13 to wind the medium 99 onto the second roll body R2.

[0103] In step S15, the control unit 20 acquires the load history information of one belt revolution. Here, the load history information of one belt revolution refers to historical information indicating the relationship between the belt rotation position and the load on the drive unit 25 at a past one belt revolution. For example, it can obtain... Figure 3 The load history information shown is obtained based on a fixed target temperature T0 for the heater. Figure 3 As shown in the graph, the load on one loop of the belt varies depending on the location. Furthermore, the measurement location for the load history information is the peeling position P2 on the conveyor belt 23. The peeling position P2 at which the load detection for creating the load history information begins is designated as the starting measurement position, from which the load history information for one loop of the belt is obtained.

[0104] In step S16, the control unit 20 calculates the tape adhesive force. The control unit 20 calculates, for example, the average load per loop of the tape based on the load history information LP. The average load is calculated by dividing the cumulative load per loop by the number of measurement points (detection points). The control unit 20 converts the average load into an adhesive force value by referring to reference data, thereby obtaining the tape adhesive force. Here, since the tape adhesive force is evaluated by the adhesion force of the medium 99, the tape adhesive force mentioned here has the same meaning as the adhesion force of the medium 99 to the adhesive layer 32. Furthermore, reference data representing the relationship between load and adhesive force is stored in memory for each type of fabric.

[0105] In step S17, the control section 20 determines whether the tape adhesion force has reached the target value. If the tape adhesion force has not reached the target value, the process proceeds to step S18. On the other hand, if the tape adhesion force has reached the target value, the process proceeds to step S21.

[0106] In step S18, the control section 20 determines whether the heating section 19 is at the maximum output. If not, the process proceeds to step S19, and after the output of the heating section 19 is increased by a predetermined amount from the current output, the process proceeds to step S14. In a case where the target value is not reached even if the output is increased by each predetermined amount to reach the maximum output (negative determination in steps S17, S18), the control section 20 proceeds to step S20.

[0107] In step S20, the control section 20 notifies information of the intention that the replacement timing of the adhesive has come. In detail, as shown in Figure 6 , the control section 20 displays a message MS aiming to promote the replacement of the adhesive on a notification screen 57 of the display section 17.

[0108] That is, the control section 20, in a case where the tape 23 has been heated at the maximum output that the heating section 19 can output (step S18), causes the notification device 14 to notify information to promote the replacement of the adhesive when the tape adhesion force based on the load current is below the threshold value.

[0109] In step S21, the control section 20 performs temperature control of the heater based on the load history information of the tape length. That is, the control section 20 controls the heating temperature of the heating section 19 based on the load history information LP of the tape length shown in Figure 3 , Figure 4 .

[0110] In step S22, the control section 20 acquires the load history information of the tape length this time. That is, the control section 20 acquires the load history information LP of the tape length shown in Figure 4 during the present tape length. The control section 20 performs the process of step S21 and the process of step S22 at each tape rotation position in the present tape length.

[0111] By the heating temperature control performed by the control section 20, the adhesion force capable of adhering with the target adhesion force can be obtained in the region where the medium 99 is adhered to the adhesive layer 32 by the pressing section 27. As a result, the medium 99 can be adhered to the adhesive layer 32 with an appropriate adhesion force.

[0112] In step S21, the control section 20 determines whether or not the printing has ended. If the printing has not ended, the process returns to step S21, and the respective processes of step S21 and step S21 are repeatedly executed. Also, if the printing has ended, the control section 20 ends the routine of the heating temperature control process.

[0113] As described in detail above, according to the present embodiment, the following effects can be obtained.

[0114] (1) The conveying system is provided with a conveying device 12 and a peeling device 13. The conveying device 12 has: a conveying belt 23 having an adhesive layer 32, and conveying a medium 99 adhered to the adhesive layer 32; a heating section 19 capable of heating the adhesive layer 32; a driving section 25 driving the conveying belt 23; and a control section 20 including a detection section 21 detecting a load of the driving section 25, and controlling the driving section 25 and the heating section 19. The peeling device 13 peels the medium 99 from the conveying belt 23. The detection section 21 is capable of detecting the load of the driving section 25 in a case where the medium 99 is peeled from the conveying belt 23 by the peeling device 13, and the control section 20 controls the heating section 19 based on a detection result of the detection section 21. According to this structure, the heating section 19 can be controlled based on the load of the driving section 25 when the actual medium 99 is peeled. When the adhering force of the medium 99 to the conveying belt 23 changes, the load of the driving section 25 when the medium 99 is peeled also changes. Therefore, the adhesive layer 32 can be heated at a temperature at which the desired adhering force can be obtained. In addition, since the load of the driving section 25 when the actual medium 99 is peeled from the adhesive layer 32 is detected, the detection accuracy of the adhering force is high. Thus, the heating section 19 can be controlled with good accuracy so that the desired adhering force can be obtained.

[0115] (2) The conveying system is provided with a notification device 14 notifying an operating condition of the conveying device 12. In a case where the heating section 19 heats the conveying belt 23 at a maximum output capable of being output, when the adhesive force based on the load current, which is one example of the load, is below a threshold value, the control section 20 causes the notification device 14 to notify information for promoting replacement of the adhesive. Therefore, the user can easily grasp the criteria for replacement of the adhesive.

[0116] (3) The conveying system is provided with an input section inputting an instruction. The threshold value can be input by the input section 18. Therefore, according to the user, the optimal threshold value can be set.

[0117] (4) The conveyance system is provided with a temperature detecting section 30 capable of detecting the temperature of the conveyance belt 23. Therefore, even during a heating preparation period (preheating period) before the load of the driving section 25 at the time when the medium 99 is peeled from the conveyance belt 23 is detected, the heating section 19 can be appropriately controlled based on the detection result of the temperature detecting section 30.

[0118] (5) The conveyance device 12 is provided with a conveyance belt 23 that conveys the medium 99 peeled by the peeling device 13. The conveyance device 12 is provided with a heating section 19 capable of heating the conveyance belt 23, a driving section 25 that drives the conveyance belt 23, and a control section 20 including a detecting section 21 that detects the load of the driving section 25 and controls the driving section 25 and the heating section 19. The conveyance belt 23 is configured to have an adhesive layer 32 and is capable of conveying the medium 99 pasted on the adhesive layer 32. The heating section 19 is configured to be capable of heating the adhesive layer 32. The detecting section 21 is configured to be capable of detecting the load of the driving section 25 in the case where the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. The control section 20 controls the heating section 19 based on the detection result of the detecting section 21. Therefore, the adhesive layer 32 can be heated at a temperature at which the required pasting force is obtained.

[0119] (6) The recording system 10 is provided with the recording device 11 and the peeling device 13. The recording device 11 is provided with a conveyance belt 23 having an adhesive layer 32 and conveying the medium 99 pasted on the adhesive layer 32. The recording device 11 has a recording section 22 capable of recording the medium 99, a heating section 19 capable of heating the adhesive layer 32, a driving section 25 that drives the conveyance belt 23, and a control section 20 including a detecting section 21 that detects the load of the driving section 25 and controls the driving section 25 and the heating section 19. The peeling device 13 peels the medium 99 from the conveyance belt 23. The detecting section 21 is capable of detecting the load current flowing to the driving section 25 in the case where the medium 99 is peeled from the conveyance belt 23 by the peeling device 13. The control section 20 is characterized in that the heating section 19 is controlled based on the detection result of the detecting section 21. According to this structure, the adhesive layer 32 can be heated at a temperature at which the required pasting force is obtained. Therefore, since the medium 99 can be pasted on the conveyance belt 23 with an appropriate pasting force, the recording accuracy is improved.

[0120] (7) A control method of a conveying device 12 having a conveying belt 23 having an adhesive layer 32 and conveying a medium 99 adhered to the adhesive layer 32, a heating section 19 capable of heating the adhesive layer 32, and a driving section 25 driving the conveying belt 23. The control method includes recording a load of the driving section 25 when the medium 99 is peeled from the conveying belt 23 (step S14) and controlling the heating section 19 based on a value of the detected load (step S21). According to the method, the adhesive layer 32 can be heated at a temperature at which a desired adhesive force can be obtained.

[0121] Second Embodiment

[0122] Next, the second embodiment will be described with reference to Figure 8 , Figure 9 . The structure of the recording system 10 is basically the same as that of the first embodiment. The control section of the peeling device 13 is different from the first embodiment in that it detects a load of a driving section of the peeling device 13.

[0123] As shown in Figure 8 , the conveying device 12 has the same control section 20 and driving section 25 as those of the first embodiment, and the control section 20 has a detection section 21. In the second embodiment, in order to distinguish these devices from the structural elements of the peeling device 13, for convenience, they are referred to as a first control section 20, a first driving section 25, and a first detection section 21.

[0124] As shown in Figure 8 , the peeling device 13 has a second control section 60 and a second driving section 65. The second control section 60 has a second detection section 61. The second driving section is a driving source of the peeling device 13, and a winding action of winding the medium 99 on a winding drum is performed by driving the second driving section 65. The second control section 60 controls the winding action of the winding drum by driving control of the second driving section 65. The second detection section 61 detects a load of the second driving section 65. The second detection section 61 is, for example, a motor driver. The second detection section 61 is realized by a load current detection function of the motor driver. The second detection section 61 detects the load of the second driving section 65 as a load current. In addition, the other structural elements constituting the recording system 10 are the same as those of the first embodiment.

[0125] The first control section 20 can communicate with the second control section 60 via the terminal device 40. The terminal device 40 receives information of the load current of the first driving section 25 detected by the first detection section 21 from the first control section 20, and receives information of the load current of the second driving section 65 detected by the second detection section 61 from the second control section 60. In the present embodiment, the first control section 20 implements the heating temperature control based on the load current of the first driving section 25 detected by the first detection section 21 and the load current of the second driving section 65 received from the second control section 60, which is different from the first embodiment. In addition, the first control section 20 can communicate with the second control section 60 directly without via the terminal device 40. In this case, the first control section 20 receives information of the load current of the second driving section 65 detected by the second detection section 61 from the second control section 60.

[0126] Hereinafter, the first embodiment will be described with reference to the drawings. Figure 9 The heating temperature control processing implemented by the first control section 20 will be described. In addition, hereinafter, the first control section 20 will be referred to as the control section 20 only in a case where it is not necessary to distinguish the first control section 20 from the second control section 60.

[0127] As for the processing of the steps Sll to S13, the control section 20 implements the same processing as the first embodiment. That is, the preheating operation is implemented in the step Sll, and when the target temperature is reached (affirmative determination in the step S12), the printing is started (step S13). When the printing is started, the medium 99 is placed on the conveyance belt 23. Thereafter, the medium 99 is conveyed by the conveyance belt 23, and the recorded medium 99 is peeled from the conveyance belt 23 by the peeling device 13. The control section 20 implements the processing from the step S31 thereafter.

[0128] In the step S31, the control section 20 detects the load of the driving section 25 of the conveyance belt 23, that is, the first load.

[0129] In the step S32, the control section 20 detects the load of the second driving section 65 as the driving section of the peeling device 13, that is, the second load. The control section 20 receives the second load information detected by the second control section 60 from the second control section 60.

[0130] In step S33, the control section 20 calculates a third load which is a load of the adhesive force, based on the first load and the second load. In detail, the control section 20 calculates a peeling load of the peeled medium 99, which is a component of the load borne by the conveyance belt 23 at the time of peeling of the medium 99, from which other components caused by contact with the cleaning section 28 or the like are removed, based on the detection result of the first detection section 21 and the detection result of the second detection section 61. Here, the load borne by the second drive section 65 from the medium 99 at the time of peeling of the medium 99 from the conveyance belt 23 is mainly the load borne from the medium 99 at the time of peeling. On the other hand, in the case where the conveyance device 12 is provided with the cleaning section 28, the load borne by the drive section 25 from the medium 99 and the load borne by the brush or the squeegee of the cleaning section 28 are included in the first load. Therefore, the control section 20 calculates a difference between the first load and the second load, for example, by the terminal device 40, thereby obtaining the third load. In detail, the terminal device 40 obtains information of the first load from the conveyance device 12 and information of the second load from the peeling device 13. Then, the terminal device 40 calculates the third load based on these information and transmits information of the third load to the first control section 20 provided in the conveyance device 12. In addition, in the case where the first control section 20 can directly communicate with the second control section 60 without going through the terminal device 40, the control section 20 can calculate a difference between the first load and the second load, thereby causing the control section 20 to obtain the third load.

[0131] In step S34, the control section 20 obtains history information of the third load for one revolution of the belt, that is, third load history information. Here, the third load history information for one revolution of the belt means history information indicating a relationship between a belt rotation position for one revolution of the belt in the past and the third load.

[0132] In step S35, the control section 20 calculates the belt adhesive force. The control section 20 calculates, for example, an average value of the third load for one revolution of the belt based on the third load history information LP. The average value of the third load is calculated by dividing a cumulative value of the third load for one revolution of the belt by the number of measurement points (detection points). The control section 20 obtains the belt adhesive force by converting the average value of the third load into a value of the adhesive force with reference to reference data. In addition, the reference data indicating a relationship between the third load and the adhesive force is stored in the memory for each kind of cloth.

[0133] In step S36, the control section 20 determines whether or not the belt adhesive force has reached a target value. If the belt adhesive force has not reached the target value, the process proceeds to step S37. On the other hand, if the belt adhesive force has reached the target value, the process proceeds to step S40.

[0134] In step S37, the control section 20 determines whether the heating section 19 is at the maximum output. If not, the routine proceeds to step S38, and after raising the output of the heating section 19 from the current output by a predetermined amount, the routine shifts to step S31. In the case where the target value is not reached even if the output is raised by each predetermined amount to reach the maximum output (negative determination in steps S36 and S37), the control section 20 proceeds to step S39.

[0135] In step S39, the control section 20 notifies information indicating that it is the time to replace the adhesive. In detail, as shown in Figure 6 the control section 20 displays a message MS aiming to promote replacement of the adhesive on a notification screen 57 of the display section 17.

[0136] In step S40, the control section 20 performs temperature control of the heater based on the third load history information of the belt for one revolution. That is, the control section 20 controls the heating temperature of the heating section 19 based on the load history information LP of the belt for one revolution shown in Figure 3 Figure 4 However, the load history information LP used in the present embodiment is the third load history information as the third load history information. That is, the load generated by the contactor of the brush or the squeegee of the cleaning section 28 or the like in contact with the conveyor belt 23 is canceled. Therefore, the control section 20 performs temperature control of the heater 19H based on the peeling load of the conveyor belt 23 from the medium 99 peeled from the conveyor belt 23.

[0137] In step S41, the control section 20 acquires the third load history information of the belt for one revolution this time. That is, the control section 20 acquires the load history information LP of the belt for one revolution shown in Figure 4 the control section 20 performs the processing of step S40 and the processing of step S41 at each belt rotation position in the belt for one revolution this time.

[0138] By the heating temperature control performed by the control section 20, the adhesive force capable of adhering with the target adhesive force can be obtained in the region where the medium 99 is adhered to the adhesive layer 32 by the pressing section 27. As a result, the medium 99 is adhered to the adhesive layer 32 with the appropriate adhesive force.

[0139] In step S42, the control section 20 determines whether the printing has ended. If the printing has not ended, the routine returns to step S40, and each of the processing of step S40 and step S41 is repeatedly executed. Also, if the printing has ended, the control section 20 ends the routine of the heating temperature control processing.

[0140] ​As described in detail above, according to the second embodiment, the following effects can be obtained.

[0141] (8) The conveying system is provided with the same conveying device 12 as the first embodiment, and a peeling device 13. The peeling device 13 is provided with a second control section 60 including a second detection section 61 that detects a load of the peeling device 13 in a case where the medium 99 is peeled from the conveying belt 23, and controls the peeling device 13. The second control section 60 transmits information of the detection result of the second detection section 61 to the control section 20. The control section 20 calculates the peeling load borne from the peeled medium 99 among the load borne by the conveying belt 23 at the time of peeling of the medium 99, based on the detection result of the detection section 21 and the detection result of the second detection section 61. Then, the control section 20 controls the heating section 19 based on the peeling load. According to this structure, the heating section 19 is controlled based on the peeling load from which the influence of the load of the contact with the conveying belt 23 is suppressed. Therefore, the heating section 19 can be controlled in a manner that a more appropriate adhesion force is obtained. As the contact, a cleaning section (for example, a cleaning brush or a cleaning blade, etc.) that cleans the conveying belt 23, etc. can be listed.

[0142] Third Embodiment

[0143] Next, the third embodiment will be described. The structure of the recording system 10 is basically the same as the second embodiment. In the second detection section 61 that is one example of the detection section included in the second control section 60 of the peeling device 13, the structure is the same as the second embodiment in that the second detection section 61 detects the load of the second drive section 65 of the peeling device 13. The control section 20 does not use the detection result of the detection section 21 in the heating temperature control processing, which is different from the respective embodiments. Therefore, in the third embodiment, the control section 20 performs the heating temperature control processing based on the detection result of the second detection section 61 that detects the load of the second drive section 65. Figure 8

[0144] Hereinafter, the heating temperature control processing will be described with reference to the flowchart of Fig. 12. Figure 9 Figure 9 In the program of the heating temperature control processing shown in Fig. 12, the control section 20 does not have the processes of step S31 and step S33. Further, in the processes of steps S34, S40, and S41, each of the processes is performed using the second load history information that is the history information of the amount of one turn of the second load instead of the third load history information. The other processes are performed in the same manner as the second embodiment. Figure 9

[0145] ​​​After the printing is started (step S13), first, in step S32, the control section 20 detects the load of the second driving section 65 of the peeling device 13, that is, the second load. The control section 20 receives the second load information detected by the second control section 60 from the second control section 60.

[0146] In the next step S34, the control section 20 acquires the history information of the second load for one revolution of the tape, that is, the second load history information. Here, the second load history information for one revolution of the tape means the history information indicating the relationship between the rotation position of the tape for one revolution of the tape in the past and the second load.

[0147] In step S35, the control section 20 calculates the tape adhesion. The control section 20, for example, calculates the average value of the second load for one revolution of the tape based on the second load history information LP. The control section 20 converts the average value of the second load into the value of the adhesion by referring to the reference data, thereby acquiring the tape adhesion. In addition, the reference data indicating the relationship between the second load and the adhesion is stored in the memory for each kind of cloth.

[0148] In step S36, the control section 20 determines whether or not the tape adhesion has reached the target value. If the tape adhesion does not reach the target value, the process proceeds to step S37. On the other hand, if the tape adhesion reaches the target value, the process proceeds to step S40.

[0149] In step S37, the control section 20 determines whether or not the heating section 19 is at the maximum output. If not, the process proceeds to step S38, and after the output of the heating section 19 is increased by a predetermined amount from the current output, the process proceeds to step S31. In the case where the target value is not reached even if the output is increased by each predetermined amount and reaches the maximum output (negative determination in steps S36 and S37), the control section 20 proceeds to step S39.

[0150] In step S39, the control section 20 notifies information indicating that the timing of the replacement of the adhesive is reached. In detail, as shown in FIG. 8, the control section 20 displays a message MS for promoting the replacement of the adhesive on the display section 17. Figure 6

[0151] In step S40, the control section 20 performs temperature control of the heater based on the second load history information for one revolution of the tape. That is, the control section 20 performs temperature control of the heater based on the second load history information LP. Figure 3 Figure 4 ​​The load history information LP of the one revolution amount of the belt is shown, and the heating temperature of the heating section 19 is controlled. However, the load history information LP used in the present embodiment is the second load history information. That is, the second load history information that does not include the load generated by the contactor of the cleaning section 28 such as a brush or a squeegee contacting the conveyance belt 23 is used, and the heating section 19 is controlled. Therefore, the control section 20 is able to perform temperature control of the heater 19H based on the peeling load received by the conveyance belt 23 from the peeled medium 99.

[0152] In step S41, the control section 20 acquires the second load history information of the one revolution amount of the belt this time. That is, the control section 20 acquires the second load history information of the one revolution amount of the belt this time in the period of the one revolution of the belt this time. Figure 4 The load history information LP of the one revolution amount of the belt is shown. The control section 20 performs the process of step S40 and the process of step S41 at each belt rotation position in the one revolution of the belt this time.

[0153] By the heating temperature control performed by the control section 20, the adhesive force capable of performing the adhesion with the target adhesion force is obtained in the region where the medium 99 is adhered to the adhesive layer 32 by the pressing section 27. As a result, the medium 99 is adhered to the adhesive layer 32 with the appropriate adhesion force.

[0154] In step S42, the control section 20 determines whether or not the printing has ended. If the printing has not ended, the process returns to step S40, and each of the processes of step S40 and step S41 is repeatedly performed. Then, if the printing has ended, the control section 20 ends the routine of the heating temperature control process.

[0155] As described in detail above, according to the third embodiment, the following effects can be obtained.

[0156] (9) The recording system 10 includes a recording device 11 and a peeling device 13. The recording device 11 includes: a conveyor belt 23 having an adhesive layer 32 and conveying a medium 99 adhered to the adhesive layer 32; a recording unit 22 capable of recording the medium 99; a heating unit 19 capable of heating the adhesive layer 32; a first drive unit 25 driving the conveyor belt 23; and a first control unit 20 controlling the first drive unit 25 and the heating unit 19. The peeling device 13 peels the medium 99 off the conveyor belt 23. The peeling device 13 includes: a second drive unit 65 driving the peeling device 13; and a second control unit 60 including a second detection unit 61 that detects the load of the second drive unit 65 and controls the second drive unit 65. The second detection unit 61 can detect the load current flowing to the second drive unit 65 when the medium 99 is peeled off the conveyor belt 23 by the peeling device 13. The first control unit 20 controls the heating unit 19 based on the detection results of the second detection unit 61. According to this structure, the heating unit 19 is controlled based on the load of the second drive unit 65 detected by the second detection unit 61 included in the second control unit 60 of the peeling device 13. The load of the second drive unit 65 does not include the load of the contact object that contacts the conveyor belt 23. Therefore, the heating unit 19 can be controlled in a way that obtains a more appropriate adhesive force. Furthermore, examples of contact objects include a cleaning unit 28 that cleans the conveyor belt.

[0157] Furthermore, the above-described embodiments can also be modified as shown in the following variations. Moreover, a further variation can be defined by appropriately combining the above-described embodiments and the variations shown below, and a further variation can also be defined by appropriately combining the variations shown below together.

[0158] Although in Figure 4 In the heating temperature control process shown, the control unit 20 performs heating temperature control at a control temperature CT that sets the minimum value of the load history information LP to a value greater than or equal to the time required for the conveyor belt 23 to rotate once (one revolution) for each control cycle. However, it is not limited to this. For example, the control unit 20 may also... Figure 10Heating temperature control is implemented at the control temperature CT shown. Here, the time (tb / N) obtained by dividing the time tb required for one rotation of the belt by a natural number N greater than 2 is set as the control period Δt. The control unit 20 implements heating temperature control at the control temperature CT obtained by performing feedback calculations to bring the detected load close to the target load L0 for each control period Δt. That is, the control unit 20 implements heating temperature control in such a way that the belt portion on the conveyor belt 23 that has reached the heating position P1 is heated according to the target temperature corresponding to its position, based on the belt rotation position and load history information LP (refer to...) corresponding to that belt portion. Figure 3 Feedback control is implemented to obtain a detection load close to the target load L0. In this way, since the control unit 20 is structured to control the heating of the heater 19H using the detection load when the medium 99 is peeled at the peeling position P2, feedback control is implemented by delaying the time required for a specific belt rotation position on the conveyor belt 23 to move from the peeling position P2 to the heating position P1. Furthermore, the target load L0 is a value greater than the minimum load required to obtain the peel strength when the medium 99 is peeled. Therefore, the result of the feedback control is that even if the load value fluctuates somewhat, a value above the required minimum load can be obtained. Furthermore, the control period Δt can be the same as or different from the load measurement period. Additionally, the control unit 20 can replace the detection load to implement feedback control that makes the adhesive force inferred from the detection load close to the target adhesive force.

[0159] Alternatively, the control of the heating unit 19 based on the detection result of the detection unit 21 can be implemented by the terminal device 40 instead of the control unit 20. Specifically, the control unit 20 can send load current information to the terminal device 40, and the terminal device 40 sends a control signal to the heating unit 19. In other words, the conveying system includes the terminal device 40, and the control unit included in the terminal device 40, upon receiving load current information detected by the detection unit 21 from the control unit 20 of the conveying device 12, sends a control signal to the heating unit 19 based on the received load current information. The drive circuit of the heating unit 19 controls the current value energized to the heater 19H based on the control signal.

[0160] Alternatively, the conveying device 12 may be equipped with a stripping section, and the control unit 20 of the conveying device 12 may control the rotational speed of the second roll body R2 held on the stripping section.

[0161] • The peeling device 13 or the peeling section can also be configured not to wind the medium 99. That is, the configuration is not particularly limited as long as the medium 99 is pulled while a predetermined tension is applied to the medium 99 discharged from the conveyance device 12. In this case, the medium 99 can also be alternately folded into multiple layers without being collected into a roll shape and then recycled.

[0162] • The terminal device 40 can also control the peeling device 13. In addition, the terminal device 40 can also control both the conveyance device 12 and the peeling device 13.

[0163] • The control section 20 can also control the driving section 25 by voltage control instead of current control.

[0164] • The detection section 21 is not limited to the current value detection function of the motor driver. For example, the load on the conveyance belt 23 can also be detected based on the speed variation of the driving section 25. The speed variation of the driving section 25 when the medium 99 is peeled from the conveyance belt 23 depends on the load on the conveyance belt 23 when the medium 99 is peeled. The control section 20 acquires the speed variation (difference) of the driving section 25 based on the detection signal of the encoder 35. The control section 20 can also control the heating section 19 based on the speed variation of the driving section 25 as the detection result of the load on the driving section 25. Alternatively, the control section 20 can also detect the load on the conveyance belt 23 based on the value of the output torque of the driving section 25 or the value of the input voltage of the driving section 25.

[0165] • The control section 20 can also control the heating section 19 based on the detection result of the belt contact type detection section described in Patent Literature 2 that contacts and rotates the conveyance belt. For example, the control section 20 can be configured to control the heating section 19 in such a manner that the heating temperature is increased when the rotation of the belt contact type detection section is stopped. In addition, the control section 20 can be configured to control the heating section 19 in such a manner that the temperature at which the required adhesion force can be obtained based on the detection result (detected number of rotations) of the detection section that detects the number of rotations of the belt contact type detection section. According to this configuration, the replacement timing of the adhesive is not only notified but also the adhesive layer 32 can be heated at a temperature at which the required adhesion force can be obtained even during the use of the conveyance belt.

[0166] • The control section 20 can also control the heating section 19 in such a manner that the required adhesion force of the adhesive layer 32 is obtained for each type of medium (for example, the type of cloth) based on the load (for example, the load current) detected by the detection section 21.

[0167] • The heating temperature control can also be a feedforward control.

[0168] • A method can also be adopted in which the adhesion force is calculated based on the load value or average load value detected by the detection section 21 when the conveyor belt 23 is rotated by a predetermined amount that is less than one rotation, without using load history information, and the heating section 19 is controlled at a temperature at which the calculated adhesion force is targeted.

[0169] • The adhesion layer can also not be a layer formed by an adhesive, but rather a layer in which the conveyor belt is composed of a material having adhesion on the surface layer. In general, the adhesion layer can be a surface layer in which the adhesion is increased by heating, and can be either a layer applied to the conveyor belt 23 or a portion of the conveyor belt 23 itself.

[0170] • The medium 99 can also be a roll of paper. In addition, the medium 99 can also be a sheet or film made of plastic, metal, laminated sheet, or ceramic.

[0171] The technical ideas and effects obtained from the above-described embodiments and modifications will be described below.

[0172] (A) A conveying system includes: a conveying device having a conveyor belt, a heating section, a driving section, and a control section, wherein the conveyor belt has an adhesion layer and conveys a medium adhered to the adhesion layer, the heating section is capable of heating the adhesion layer, the driving section drives the conveyor belt, and the control section includes a detection section that detects a load of the driving section and controls the driving section and the heating section; and a peeling device that peels the medium from the conveyor belt, the detection section is capable of detecting the load of the driving section when the medium is peeled from the conveyor belt by the peeling device, and the control section controls the heating section based on the detection result of the detection section.

[0173] According to the above-described structure, the heating section can be controlled based on the load of the driving section when the actual medium is peeled. When the adhesion of the medium to the conveyor belt changes, the load of the driving section when the medium is peeled also changes. Therefore, the adhesion layer can be heated at a temperature at which the desired adhesion can be obtained. In addition, since the load of the driving section when the medium is actually peeled from the adhesion layer is detected, the detection accuracy of the adhesion is high. Thus, the heating section can be controlled with good accuracy so that the adhesion layer obtains the desired adhesion.

[0174] (B) In the above-described conveyance system, the following can also be employed, that is, a notification device that notifies of the operation state of the conveyance device is provided, and in a case where the heating section heats the conveyance belt at the maximum output that can be output, the control section causes the notification device to notify of information that promotes replacement of the adhesive when the adhesion force based on the load is below a threshold value.

[0175] According to the above-described structure, the user can easily grasp the criteria for replacement of the adhesive.

[0176] (C) In the above-described conveyance system, the following can also be employed, that is, an input section that inputs an instruction is provided, and the threshold value can be input through the input section.

[0179] According to the above-described structure, even during a heating preparation period before the load of the driving section at the time when the medium is peeled from the conveyance belt is detected, the heating section can be appropriately controlled based on the detection result of the temperature detection section.

[0180] (E) In the above-described conveyance system, the following can also be employed, that is, the peeling device is provided with a second control section that includes a second detection section that detects the load of the peeling device in a case where the medium is peeled from the conveyance belt, and transmits information of the detection result of the second detection section to the control section, and the second control section controls the peeling device, and the control section calculates the peeling load that is borne from the peeled medium, among the load borne by the conveyance belt at the time when the medium is peeled, based on the detection result of the detection section and the detection result of the second detection section, and controls the heating section based on the peeling load.

[0181] According to the above-described structure, the heating section is controlled based on the peeling load from which the influence of the load of the contact that contacts the conveyance belt is suppressed. Therefore, the heating section can be controlled in a manner that more appropriate adhesion force is obtained. In addition, as the contact, a cleaning section that cleans the conveyance belt or the like can be cited.

[0182] (F) The conveying device is a conveying device provided with a conveying belt that conveys a medium peeled by a peeling device, the conveying device being provided with: a heating section that can heat the conveying belt; a driving section that drives the conveying belt; and a control section that includes a detection section that detects a load of the driving section and controls the driving section and the heating section, the conveying belt being configured to have an adhesive layer and to convey the medium pasted on the adhesive layer, the heating section being configured to heat the adhesive layer, the detection section being configured to detect the load of the driving section in a case where the medium is peeled from the conveying belt by the peeling device, and the control section controlling the heating section based on a detection result of the detection section.

[0183] According to the above structure, the adhesive layer can be heated at a temperature at which a desired pasting force is obtained.

[0185] According to the above structure, the heating section is controlled based on the load of the second driving section detected by the detection section included in the second control section of the peeling device. The load of the second driving section does not include a load of a contactor that contacts the conveying belt. Therefore, the heating section can be controlled in a manner in which a more appropriate pasting force is obtained. In addition, as the contactor, a cleaning section that cleans the conveying belt or the like can be cited.

[0186] (H) A control method of a conveyance device having a conveyance belt, a heating section, and a driving section, wherein the conveyance belt has an adhesive layer and conveys a medium adhered to the adhesive layer, the heating section is capable of heating the adhesive layer, and the driving section drives the conveyance belt, the control method of the conveyance device including detecting a load of the driving section when the medium is peeled from the conveyance belt and controlling the heating section based on a value of the detected load.
