[0014] Hereinafter, the present invention will be described in summary.

[0015] To address the aforementioned issues, the winding apparatus according to the first aspect of the present invention is characterized in that, while conveying a medium formed by attaching fabric to a support member having an adhesive surface along a conveying direction, the winding apparatus simultaneously peels the fabric from the support member and winds it up, and comprises: a first winding shaft for winding the support member; a second winding shaft for winding the fabric peeled off from the support member; a first clamping roller for clamping the medium at an upstream position in the conveying direction of the first and second winding shafts; and a second clamping roller for clamping the fabric at a downstream position in the conveying direction compared to the first clamping roller, wherein the peeling position where the fabric is peeled off from the support member is a position between a first clamping position where the first clamping roller clamps the medium and a second clamping position where the second clamping roller clamps the fabric.

[0016] According to this method, the stripping position where the fabric is peeled from the support member is between the first clamping position where the first clamping roller clamps the medium and the second clamping position where the second clamping roller clamps the fabric. The fabric, positioned between the first and second clamping positions, is conveyed in a flat manner while being clamped by both the first and second clamping rollers at both the upstream and downstream sides in the fabric's conveying direction. Therefore, the fabric is stripped from the support member at the flattened position, meaning that the bending of the fabric is suppressed, thus preventing curling and shrinkage.

[0017] The second aspect of the present invention relates to a winding and taking-off method that is subordinate to the first aspect, characterized in that, when the direction of the support member from the peeling position toward the support member of the first winding shaft is set as the first direction, and the conveying direction of the medium toward the peeling position is set as the second direction, the first winding shaft is arranged at a position where the angle between the first direction and the second direction is an acute angle.

[0018] According to this method, the first take-up shaft is positioned at an acute angle θ formed by a first direction (as the direction of the support member from the peeling position toward the support member of the first take-up shaft) and a second direction (as the conveying direction of the medium toward the peeling position). Therefore, the force exerted by the first take-up shaft on the support member can be effectively converted into a force for peeling the fabric.

[0019] The third aspect of the present invention relates to a winding and placement method subordinate to the first aspect, characterized in that the first winding shaft is configured in a position in which the component of the winding force of the support member after the fabric has been peeled off is such that it includes a component in the opposite direction to the transport direction of the medium toward the peeled position.

[0020] According to this method, the first take-up shaft is positioned such that the component of the winding force by which the support member, after the fabric has been peeled off, is wound by the first take-up shaft includes a component in the opposite direction to the conveying direction. Therefore, since the component in the opposite direction to the conveying direction acts as a force peeling the support member from the fabric, the winding force generated by the first take-up shaft can be effectively converted into a peeling force.

[0021] The fourth aspect of the present invention relates to a winding and placement method subordinate to the first aspect, characterized in that it comprises: a detection unit that detects the winding amount of the support member wound by the first winding shaft; and a control unit that controls the winding speed of the support member performed by the first winding shaft based on the winding amount.

[0022] In addition, this method can also be subordinate to the second or third method.

[0023] The support medium is wound into a roll by the first take-up shaft, but the diameter of the roll gradually increases. When the winding speed of the first take-up shaft, i.e., the movement speed of the support member toward the roll, is kept constant, the peeling position where the fabric is peeled from the support member shifts as the diameter of the roll increases. That is, the peeling position moves towards the second clamping roller, making it impossible to maintain the fabric between the first clamping position and the second clamping position.

[0024] According to this method, it is configured such that the detection unit detects the amount of winding of the support member wound by the first winding shaft, and the control unit controls the winding speed based on the amount of winding. Thus, by controlling the winding speed to increase, the peeling position where the fabric is detached from the support member can be maintained between the first clamping position and the second clamping position.

[0025] The fifth aspect of the present invention relates to a winding and placement method that is subordinate to the fourth aspect, characterized in that the detection unit includes a driven roller that contacts the support member after the fabric has been peeled off, and the control unit determines the winding amount based on the rotation of the driven roller.

[0026] According to this method, the detection unit includes a driven roller that contacts the support member after the fabric has been peeled off. Furthermore, the control unit is configured to determine the winding amount based on the rotation of the driven roller. Thus, the winding speed can be controlled using such a simple structure as the driven roller.

[0027] The sixth aspect of the present invention relates to a winding and placement method subordinate to the first aspect, characterized in that it includes a first detection unit and a second detection unit, which are disposed separately at a position for clamping the support member after the fabric has been peeled off, and are capable of detecting the distance from the support member; and a control unit that controls the winding speed of the support member performed by the first winding shaft based on the distance.

[0028] In addition, this method can also be subordinate to the second or third method.

[0029] According to this method, a first detection unit and a second detection unit are provided, which are separately arranged at the position where the support member after the fabric has been peeled off is clamped, and are capable of detecting the distance from the support member. The control unit is configured to control the winding speed of the support member performed by the first winding shaft based on the distance. Therefore, the position where the support member has been peeled off from the fabric can be maintained between the first clamping position and the second clamping position.

[0030] The seventh aspect of the present invention relates to a winding and taking-up method subordinate to the first aspect, characterized in that it includes a drying section that dries the medium, and the first clamping roller and the second clamping roller are respectively disposed at a position downstream of the drying section and a position upstream of the drying section in the conveying direction, and the first winding shaft is also disposed at both positions corresponding to the first clamping roller and the second clamping roller at the downstream position and the first clamping roller and the second clamping roller at the upstream position.

[0031] In addition, this method can also belong to any one of the methods from the second to the sixth method.

[0032] For adhesives forming the bonding surfaces, there exists a type where the adhesive strength weakens due to heat. In the case of such adhesives, peeling becomes easier after the drying process performed by the drying section.

[0033] On the other hand, there is a type of adhesive whose adhesive strength increases with heat. Furthermore, there is a type of support member that is prone to wrinkling due to heat, similar to a paper substrate. Additionally, it is sometimes desirable to shorten the drying time by using the monomers after the fabric has been peeled from the support member for drying.

[0034] According to this method, the first clamping roller and the second clamping roller are respectively positioned downstream of the drying section and upstream of the drying section in the conveying direction. Furthermore, the first take-up shaft is also respectively positioned at both the downstream and upstream clamping rollers. Therefore, the user can appropriately select and execute a configuration that results in better peeling after drying and better peeling before drying.

[0035] The eighth aspect of the present invention relates to a winding and placement method subordinate to the first aspect, characterized in that it includes a drying section that dries the medium, the first clamping roller and the second clamping roller are configured to be movable in the conveying direction between a position downstream of the drying section and a position upstream of the drying section, and the first winding shaft is also configured to be movable in the conveying direction between a position downstream of the drying section and a position upstream of the drying section.

[0036] In addition, this method can also belong to any one of the methods from the second to the sixth method.

[0037] According to this method, the assembly of the first clamping roller and the second clamping roller with the first take-up shaft is configured to move between a position upstream of the drying section and a position downstream of the drying section. Thus, similar to the seventh method, the user can appropriately select and execute whether peeling is better after drying or before drying.

[0038] The recording and placement according to the ninth aspect of the present invention is characterized by comprising: an unwinding section that unwinds a roll of medium formed by attaching fabric to a support member having an adhesive surface along a conveying direction; a recording section that records the medium; and a winding device located downstream of the recording section in the conveying direction and separately winding up the support member and the fabric, wherein the winding device is a winding device described in any one of the first to eighth aspects.

[0039] According to this method, as a recording device, it is possible to obtain the effect that can be obtained using any one of the first to eighth methods.

[0040] Implementation The following is based on Figures 1 to 7 The following is a detailed description of the winding device and recording device involved in the embodiments of the present invention.

[0041] In the following description, as shown in the figures, the three mutually orthogonal axes are designated as the X-axis, Y-axis, and Z-axis. The arrows on the three axes (X, Y, Z) indicate the positive (+) direction and the negative (-) direction, respectively. The Z-axis corresponds to the vertical direction, i.e., the direction in which gravity exerts its force; the +Z direction represents vertically upward, and the -Z direction represents vertically downward. The X-axis and Y-axis correspond to the horizontal direction. The +Y direction represents the forward direction of the recording device, and the -Y direction represents the rearward direction. The +X direction represents the rightward direction of the recording device, and the -X direction represents the leftward direction.

[0042] Implementation Method 1 The recording device 1 in this embodiment is an inkjet printer as an example.

[0043] like Figure 1 As shown, the recording device 1 includes an unwinding section 3 for unwinding the medium 2 along the conveying direction F, a recording section 4, and a winding device 5.

[0044] The medium 2 is a roll-shaped medium formed by attaching a sheet-shaped fabric 8 to a sheet-shaped support member 7 having an adhesive surface 6. The medium 2 is placed on the unwinding section 3 in the state of a roll body R1. The unwinding section 3 rotates the roll body R1 to unwind the medium 2 along the transport direction F. The recording section 4 sprays ink onto the unwound fabric 8 of the medium 2 in the recording execution area 9 to perform recording. In the recording execution area 9, the medium 2 is supported by the medium support section 10. The winding device 5 will be described later.

[0045] like Figure 1 As shown, the recording device 1 also includes a conveying section 11 that applies a conveying force to the medium 2 toward the recording section 4, intermediate rollers 12 and 13, and a drying section 14.

[0046] The conveying unit 11 consists of a conveying roller 111 that rotates due to power transmitted from a drive source and a pressing roller 112 that rotates following the rotation of the conveying roller 111. Intermediate rollers 12 and 13 are positioned to change the conveying direction F of the medium 2 and rotate followingly as the medium 2 moves in the conveying direction F. The drying unit 14 heats the cloth 8 from which the ink-sprayed medium 2 is applied to dry it.

[0047] like Figure 1 As shown, the recording device 1 also includes a pressing part 15. The pressing part 15 is located upstream of the recording part 4 and the conveying part 11 in the conveying direction F. The pressing part 15 is configured to clamp the medium 2 moving along the conveying direction F and apply a pressing force P to press it. The pressing part 15 is configured such that the pressing force P on the medium 2 can be adjusted according to the type of medium 2 by means of the adjusting part 16. The adjusting part 16 can be any structure that can adjust the pressing force P by increasing or decreasing it. Although a structure using a spring and a cam can be given as an example, it is not limited to a specific structure.

[0048] In this embodiment, for multiple types of media 2 intended for use, the appropriate pressing pressure P is determined through pre-prototyping or the like. It is configured such that the user determines the type of media 2 via an operation panel (not shown), and the corresponding pressing pressure P is applied to the media 2 via the adjustment unit 16.

[0049] winding device Next, based on Figure 1 The structure of the winding device 5 according to Embodiment 1 will be described.

[0050] The winding device 5 conveys the medium 2, which is formed by attaching fabric 8 to the support member 7 having adhesive surface 6, along the conveying direction F, while peeling the fabric 8 from the support member 7 and winding it up separately. The winding device 5 includes a first winding shaft 17 for winding the support member 7 and a second winding shaft 18 for winding the fabric 8 peeled from the support member 7.

[0051] Furthermore, the winding device 5 includes a first clamping roller 19 and a second clamping roller 20. The first clamping roller 19 is positioned upstream of the first winding shaft 17 and the second winding shaft 18 in the conveying direction F. The first clamping roller 19 clamps, i.e. holds, the medium 2 at the first clamping position B1. The second clamping roller 20 is positioned downstream of the first clamping roller 19 in the conveying direction F. The second clamping roller 20 clamps, i.e. holds, the fabric 8 at the second clamping position B2.

[0052] In this embodiment, the first take-up shaft 17 and the second take-up shaft 18, as well as the first clamping roller 19 and the second clamping roller 20, are arranged on the downstream side of the conveying direction F of the drying section 14. The fabric 8 is conveyed in a flat manner while being clamped by the first clamping roller 19 and the second clamping roller 20 on both the upstream and downstream sides of the conveying direction F of the fabric 8.

[0053] Furthermore, the winding device 5 is configured such that the peeling position A, where the fabric 8 is peeled from the support member 7, is between the first clamping position B1 and the second clamping position B2. That is, it is configured such that the winding speed V1 of the first winding shaft 17 and the winding speed V2 of the second winding shaft 18 are controlled by the control unit 21 to be the same speed, and the peeling position A is the position between the first clamping position B1 and the second clamping position B2.

[0054] The position between the first clamping position B1 and the second clamping position B2 is, as the name suggests, "the position between", excluding the first clamping position B1 and the second clamping position B2.

[0055] Although the appropriate interval between the first clamping position B1 and the second clamping position B2 may vary depending on the type of medium 2, it is preferable to set it in the range of 30 mm to 150 mm, since the flatness of the fabric 8 at the peeling position A is easily reduced if the interval is too large.

[0056] In this embodiment, when the direction of the support member 7 from the peeling position A toward the support member 7 of the first take-up shaft 17 is set as the first direction D1, and the conveying direction F of the medium 2 toward the peeling position A is set as the second direction D2, the first take-up shaft 17 is arranged at a position where the angle θ formed by the first direction D1 and the second direction D2 is an acute angle.

[0057] Furthermore, the case where angle θ is an acute angle can be specified in the following manner.

[0058] The first take-up shaft 17 is positioned such that the component of the winding force G used to wind up the support member 7 after the fabric 8 has been peeled off is a component G1 that includes a component G1 that is opposite to the conveying direction F of the medium 2 toward the peeling position A. The symbol G2 indicates other components.

[0059] In other words, the first take-up shaft 17 is positioned such that the support member 7 is peeled off at an acute angle relative to the fabric 8 located between the first clamping position B1 and the second clamping position B2. Alternatively, the first take-up shaft 17 is positioned such that the angle between the surface of the support member 7 before the fabric 8 is peeled off and the surface of the support member 7 after the fabric 8 is peeled off is an acute angle.

[0060] In this embodiment, a detection unit 23 is also provided, which detects the winding amount M of the support member 7 wound by the first take-up shaft 17. Furthermore, the control unit 21 is configured to control the winding speed V1 of the support member 7 operated by the first take-up shaft 17 based on the winding amount M.

[0061] Here, the detection unit 23 includes a driven roller 24, which contacts the support member 7 after the fabric 8 has been peeled off, and rotates in response to the movement of the support member 7. The control unit 21 is configured to calculate and determine the winding amount M based on the rotation of the driven roller 24.

[0062] Although the support member 7 is wound up by the first take-up shaft 17 to form a roll body R2, the diameter of the roll body R2 gradually increases. When the winding speed V1 of the first take-up shaft 17, that is, the moving speed of the support member 7 toward the roll body R2, is kept constant, the support member 7 will gradually shift from the peeling position A where the fabric 8 is peeled off as the diameter of the roll body R2 increases.

[0063] That is, the peeling position A will gradually move towards the second clamping roller 20 side which is downstream of the conveying direction F, so that it is impossible to maintain between the first clamping position B1 and the second clamping position B2.

[0064] An increase in the winding amount M means an increase in the diameter of the roll body R2. Therefore, by knowing the winding amount M, we can understand the displacement state of the peeling position A.

[0065] In this embodiment, the control unit 21 controls the winding speed V1 based on the calculated winding amount M, so as to maintain the peeling position A between the first clamping position B1 and the second clamping position B2. Specifically, the control is performed such that when the winding amount M reaches a set value, the winding speed V1 is increased.

[0066] The relationship between the winding amount M and the winding speed V1 used to maintain the peeling position A between the first clamping position B1 and the second clamping position B2 is determined through pre-test operation, etc. Specifically, when the winding amount M reaches a set value, the winding speed is increased from V1 to V1+α based on the pre-determined relationship between the winding amount M and the winding speed V1. Here, α represents the amount of increase in winding speed and is pre-set in such a way that the peeling position A moves away from the second clamping roller 20.

[0067] In this embodiment, the winding speed V1 is adjusted by changing the rotational speed of the first winding shaft 17. Furthermore, in this embodiment, the user can directly adjust the rotational speed of the first winding shaft 17 by omitting the speed adjustment section shown in the figure.

[0068] That is, it is configured such that when the user confirms the displacement of the peeling position A and confirms that the peeling position A is gradually moving toward the second clamping roller 20, in addition to adjusting the winding speed V1 based on the winding amount M, the winding speed V1 can also be further adjusted by the speed adjustment unit so as to keep the peeling position A between the first clamping position B1 and the second clamping position B2.

[0069] Furthermore, in this embodiment, it is configured such that when the winding speed V1 of the first winding shaft 17 is changed, the winding speed V2 of the second winding shaft 18 also changes accordingly, thus becoming the same speed as the first winding speed V1. The fabric 8 is wound up by the second winding shaft 18 to form a roll R3.

[0070] The operations of the unwinding unit 3, pressing unit 15, conveying unit 11, recording unit 4, drying unit 14, first take-up shaft 17, second take-up shaft 18, and detection unit 23 are controlled by the control unit 21. Here, the control unit 21 includes a CPU, a flash ROM, and RAM. The CPU performs various arithmetic operations according to a program stored in the flash ROM and controls the overall operation of the recording device 1. As an example of a storage unit, the flash ROM is a non-volatile memory capable of being read and written. As an example of a storage unit, RAM temporarily stores various types of information.

[0071] From the placement of the roll body onto the recording device until the start of rewinding. First, the roll body R1 is placed on the unwinding section 3. The top end of the medium 2 is pulled out from the placed roll body R1 and passes through the conveying path formed by the pressing section 15, the conveying section 11, the recording section 4, the intermediate rollers 12 and 13, the drying section 14 and the first clamping roller 19.

[0072] The support member 7 and the fabric 8 of the medium 2 are peeled off near the front of the second clamping roller 20. The support member 7 is wound around the first take-up shaft 17, passing through the detection area of ​​the detection unit 23. The fabric 8 is wound around the second take-up shaft 18, passing through the second clamping roller 20. Thus, the peeling position A is located between the first clamping position B1 and the second clamping position B2.

[0073] In this state, when recording begins, the medium 2 is conveyed in the transport direction F under the control of the control unit 21, ink is ejected by the recording unit 4 to perform recording, drying is performed by the drying unit 14, and it is wound up by the winding device 5.

[0074] Winding performed by the winding device The winding device 5 rotates the first winding shaft 17 to wind up the support member 7 and the second winding shaft 18 to wind up the fabric 8. The winding of the support member 7 and the fabric 8 is performed with the peeling position A located between the first clamping position B1 and the second clamping position B2. The winding speed V1 of the first winding shaft 17 and the winding speed V2 of the second winding shaft 18 are set to be the same.

[0075] The fabric 8, positioned between the first clamping position B1 and the second clamping position B2, is conveyed in a flat manner while being clamped by the first clamping roller 19 and the second clamping roller 20 at both the upstream and downstream sides in the conveying direction F of the fabric 8. That is, at the location where the fabric 8 is held in a flat position, the support member 7 is peeled off from the fabric 8.

[0076] Variations of Implementation Method 1 Figure 2 A variation of embodiment 1 is shown.

[0077] Based on Implementation 1 Figure 1 In the above description, the first take-up shaft 17 and the second take-up shaft 18, as well as the first clamping roller 19 and the second clamping roller 20, are arranged on the downstream side of the conveying direction F of the drying section 14.

[0078] In contrast, in this variant example, such as Figure 2 As shown, the first take-up shaft 17 and the second take-up shaft 18, as well as the first clamping roller 19 and the second clamping roller 20, are disposed upstream of the drying section 14 in the conveying direction F. The drying section 14 is disposed between the second clamping roller 20 and the second take-up shaft 18. This is the only difference; the other structures remain unchanged.

[0079] Explanation of the effects of Implementation Method 1 (1) In this embodiment, the peeling position A where the fabric 8 is peeled from the support member 7 is the position between the first clamping position B1 where the first clamping roller 19 clamps the medium 2 and the second clamping position B1 where the second clamping roller 20 clamps the fabric 8. The fabric 8, located between the first clamping position B1 and the second clamping position B2, is conveyed in a flat manner while being clamped by the first clamping roller 19 and the second clamping roller 20 at both the upstream and downstream sides in the conveying direction F of the fabric 8. As a result, the fabric 8 is peeled from the support member 7 at the part where the fabric 8 is held in a flat manner, that is, the bending of the fabric 8 is suppressed as in the past, thus suppressing the situation where the fabric 8 curls and wrinkles.

[0080] (2) Furthermore, in this embodiment, the first take-up shaft 17 is positioned at an acute angle θ formed by a first direction D1, which is the direction of the support member 7 from the peeling position A toward the support member 7 of the first take-up shaft 17, and a second direction D2, which is the conveying direction F of the medium 2 toward the peeling position A. Therefore, the winding force G of the first take-up shaft 17 winding the support member 7 can be effectively converted into a force for peeling from the fabric 8.

[0081] (3) Furthermore, in this embodiment, the first take-up shaft 17 is positioned such that the component of the winding force G that the support member 7, after the fabric 8 has been peeled off, is wound by the first take-up shaft 17 includes a component G1 in the opposite direction to the conveying direction F. Therefore, since the component G1 in the opposite direction to the conveying direction F functions as a force that peels the support member 7 from the fabric 8, the winding force G generated by the first take-up shaft 17 can be effectively converted into a peeling force.

[0082] (4) The support medium 7 is wound up by the first take-up shaft 17 to form a roll body R1, but the diameter of the roll body R1 gradually increases. When the winding speed V1 of the first take-up shaft 17, that is, the moving speed of the support member 7 toward the roll body R1, is kept constant, as the diameter of the roll body R1 increases, the peeling position A where the fabric 8 is peeled off from the support member 7 will gradually shift. That is, the peeling position A will move toward the second clamping roller 20, thus making it impossible to maintain it between the first clamping position B1 and the second clamping position B2.

[0083] In this embodiment, the system is configured such that the detection unit 23 detects the winding amount M of the support member 7 wound by the first winding shaft 17, and the control unit 21 controls the winding speed V1 based on the winding amount M. Therefore, by controlling the winding speed V1 to increase, the peeling position A where the fabric 8 is peeled from the support member 7 can be maintained between the first clamping position B1 and the second clamping position B2.

[0084] (5) Furthermore, in this embodiment, the detection unit 23 includes a driven roller 24 that contacts the support member 7 after the fabric 8 has been peeled off. Moreover, the control unit 21 is configured to determine the winding amount M based on the rotation of the driven roller 24. Thus, the winding speed V1 can be controlled using such a simple structure as the driven roller 24.

[0085] Implementation Method 2 Next, based on Figure 3 The winding device 5 according to Embodiment 2 will now be described. The same symbols are used for parts identical to those in Embodiment 1, and descriptions of their structure and corresponding effects are omitted.

[0086] In this embodiment, the first clamping roller 19 and the second clamping roller 20 are respectively positioned downstream of the drying section 14 and upstream of the drying section 14 in the conveying direction F. Furthermore, the first take-up shaft 17 is also positioned at both the downstream and upstream positions of the first clamping roller 19 and the second clamping roller 20 of the drying section 14. In this embodiment, as... Figure 3 As shown, the detection unit 23 is also similarly disposed at both of the two locations.

[0087] Figure 3 The diagram shows the state of the assembly of the first clamping roller 19 and the second clamping roller 20, which are positioned upstream of the drying section 14, along with the first take-up shaft 17 and the detection section 23.

[0088] For the adhesive forming the bonding surface 6, there is a type where the adhesive strength weakens due to heat. In the case of this type of adhesive, peeling becomes easier after the drying process performed by the drying section 14.

[0089] On the other hand, there is a type of adhesive whose adhesive strength increases with heat. Furthermore, there is a type of support member 7 that is prone to wrinkling due to heat, similar to a paper substrate. Additionally, it is sometimes desirable to shorten the drying time by using the monomers after the fabric 8 has been peeled from the support member 7 for drying.

[0090] In this embodiment, as described above, the first clamping roller 19 and the second clamping roller 20 are respectively positioned downstream of the drying section 14 and upstream of the drying section 14 in the conveying direction F. Furthermore, the first take-up shaft 17 is also positioned at both the downstream and upstream positions corresponding to the first clamping roller 19 and the second clamping roller 20.

[0091] Therefore, as the position for peeling the cloth 8 from the support member 7, the user can appropriately select and perform the situation where peeling is better after the drying process performed by the drying unit 14 and before the drying process.

[0092] Implementation Method 3 Next, based on Figure 4 The winding device 5 according to Embodiment 3 will now be described. The same symbols are used for parts identical to those in Embodiment 1, and descriptions of their structure and corresponding effects are omitted.

[0093] In this embodiment, the first clamping roller 19 and the second clamping roller 20 are configured to move in the conveying direction F between a position downstream of the drying section 14 and a position upstream of the drying section 14. Here, the drying section 14 is configured to be separable into an upper part and a lower part. It is configured such that the first clamping roller 19 and the second clamping roller 20 can move between the upstream position and the downstream position by separating the upper and lower parts of the drying section 14.

[0094] Furthermore, the first take-up shaft 17 is configured to move in the conveying direction F between a position downstream of the drying section 14 and a position upstream of the drying section 14. The first take-up shaft 17 is configured such that it is arranged on a moving track (not shown) and can move between the upstream and downstream positions. In this embodiment, the detection unit 23 is also configured to move in the conveying direction F between a position downstream of the drying section 14 and a position upstream of the drying section 14. The detection unit 23 is also configured such that it is arranged on a moving track (not shown) and can move between the upstream and downstream positions.

[0095] In this embodiment, the assembly of the first clamping roller 19 and the second clamping roller 20 with the first take-up shaft 17 is configured to move between a position upstream of the drying section 14 and a position downstream of the drying section 14. Thus, similar to Embodiment 3, the user can appropriately select and perform either a better peeling condition after the drying process performed by the drying section 14 or a better peeling condition before the drying process.

[0096] Figure 4 The diagram shows a configuration where the first clamping roller 19 and the second clamping roller 20, together with the first take-up shaft 17 and the detection unit 23, are positioned upstream of the drying unit 14.

[0097] Implementation Method 4 Next, based on Figures 5 to 7 The winding device 5 according to Embodiment 4 will now be described. The same symbols are used for parts identical to those in Embodiment 1, and descriptions of their structure and corresponding effects are omitted.

[0098] In this embodiment, a first detection unit 25 and a second detection unit 26 are provided. The first detection unit 25 and the second detection unit 26 are arranged separately at the position where the support member 7 after the fabric 8 has been peeled off is clamped, and the distance to the support member 7 can be detected. Furthermore, the control unit 21 controls the winding speed V1 of the support member 7 operated by the first winding shaft 17 based on the distance. In this embodiment, the control unit 21 is configured to control the winding speed V1 of the first winding shaft 17 based on the cases where the distance between the support member 7 and the first detection unit 25 is zero, and the cases where the distance between the support member 7 and the second contact part 26 is zero. Alternatively, it can be configured to control the winding speed V1 of the first winding shaft 17 based on the cases where the distance to the support member 7 is detected by the first detection unit 25 as being below a predetermined value, and the cases where the distance to the support member 7 is detected by the second detection unit 26 as being below a predetermined value.

[0099] Winding performed by the winding device When in Figure 5 In the state shown, as the first take-up shaft 17 continues to wind the support member 7 at a take-up speed V1, the diameter of the roll body R2 gradually increases. Furthermore, the peeling position A gradually moves towards the second clamping roller 20. Through this movement, the distance between the first detection unit 25 and the support member 7 gradually decreases.

[0100] like Figure 6 As shown, when the support member 7 comes into contact with the first detection unit 25 and the distance becomes zero, the control unit 21 increases the winding speed from V1 to V1+α. Here, α represents the amount of increase in winding speed as described above, and is preset in such a way that the peeling position A moves away from the second clamping roller 20.

[0101] As the first take-up shaft 17 continues to wind the support member 7 at a take-up speed V1+α, the peeling position A moves towards the first clamping roller 19. For example... Figure 7 As shown, when the support member 7 contacts the second detection unit 26 and the distance becomes zero, the control unit 21 is configured to return the winding speed from V1+α to V1. Consequently, the peeling position A gradually moves away from the second detection unit 26. Afterwards, it becomes... Figure 5 , Figure 6 , Figure 7 The state is repeated.

[0102] In this embodiment, a first detection unit 25 and a second detection unit 26 are provided. The first detection unit 25 and the second detection unit 26 are arranged separately at the position where the support member 7 after the fabric 8 has been peeled off is clamped, and the distance to the support member 7 can be detected. The control unit 21 is configured to control the winding speed V1 of the support member 7 operated by the first winding shaft 17 based on the distance. As a result, the position A where the support member 7 is peeled off from the fabric 8 can be maintained between the first clamping position B1 and the second clamping position B2.

[0103] Other implementation methods Although the winding device 5 and the recording device 1 of the present invention are based on the structure of the embodiments described above, it is of course possible to implement some structural changes or omissions without departing from the spirit of the present invention.

[0104] Although the above explanation addresses the case where angle θ is acute, it is not a limitation. That is, angle θ can also be obtuse.

[0105] Furthermore, as a structure for maintaining the peeling position A between the first clamping position B1 and the second clamping position B2, a detection unit 23 is provided in Embodiments 1 to 3, and a first detection unit 25 and a second detection unit 26 are provided in Embodiment 4. Alternatively, the structure can be configured such that, without providing these detection units 23 or the first and second detection units 25 and 26, the user directly adjusts the rotational speed of the first take-up shaft 17 using the speed adjustment unit described in Embodiment 1.
