It is the figure which looked at the machine base for winding parts in an inkjet recording device from the feed direction downstream side. It is the figure which looked at the stand for winding parts in an inkjet recording device from the apparatus left side. FIG. 4 is an enlarged view of a portion surrounded by an alternate long and short dash line in FIG. 3. It is a figure which shows the state which changed or removed the connection position in the vertical direction with respect to the vertical frame part of an upper horizontal frame part according to the kind of heater unit mounted.

  Hereinafter, an ink jet recording apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings. This ink jet recording apparatus prints (prints) a pattern or the like on a cloth (original fabric) to be supplied and discharged in a so-called reel-to-reel format using a dye ink exclusively by an ink jet method. In the following description, the forward / reverse feeding direction of the recording medium that is a fabric is defined as the X-axis direction, and the direction orthogonal to the X-axis direction is defined as the Y-axis direction.

  FIG. 1 is a cross-sectional structure diagram of an ink jet recording apparatus. As shown in the figure, the inkjet recording apparatus 1 includes a feeding unit 2 that feeds and feeds a recording medium W wound in a roll shape, and a printing medium W that is fed for printing along a feeding path 3. A main body 4 to be sent, a printing unit 5 which is disposed on the upper side of the main body 4 and performs printing on the recording medium W by an inkjet method in cooperation with the main body 4, and a recording medium W printed by the printing unit 5. A winding unit 6 that winds and collects on the downstream side in the feed direction of the apparatus main body 4 and a control unit 7 that performs overall control of these constituent devices are provided.

  The apparatus main body 4 includes a main body base 11 configured by assembling steel materials, and a medium feeding mechanism 12 supported by the main body base 11 and intermittently feeding the recording medium W in the X-axis direction by belt conveyance. ing. The printing unit 5 includes a carriage unit 14 having an inkjet head 15 and a head moving mechanism 16 that reciprocates the carriage unit 14 in the Y-axis direction. On the other hand, the feeding unit 2 includes a feeding unit 18 that feeds out the recording medium W, and a loosening unit 19 that takes out the slack of the recording medium W that has been fed out. The winding unit 6 also includes a winding unit 21 that winds the recording medium W, a slip sheet unit 22 that supplies the slip sheet P to the winding unit 21, and a recording medium W that is immersed before the recording medium W is wound. And a heater unit 23 for vaporizing the solvent (moisture) of the incorporated dye ink, and these units are mounted on a winder unit base 24.

  The recording medium W (fabric) fed out from the feeding unit 18 is slackened so as to be stretched by the slackening unit 19 and fed into the medium feeding mechanism 12. The recording medium W sent to the medium feeding mechanism 12 is conveyed by a belt so as to adhere to the surface. In this belt conveyance, the recording medium W is intermittently fed in the X-axis direction (sub scanning), while the carriage unit 14 reciprocates in the Y-axis direction in synchronization with this, and ink is ejected from the inkjet head 15 ( Main scan).

  In this way, after printing is performed, the printed portion (printed portion) of the recording medium W is sent out from the medium feeding mechanism 12 to the winding unit 6. In the winding unit 6, the slip sheet P is continuously supplied from the slip sheet unit 22 to the recording medium W sent from the medium feed mechanism 12, and the record medium W and the slip sheet P are overlapped and fed to the heater unit 23. It is done. In the heater unit 23, the recording medium W is heated together with the interleaving paper P, and the solvent (moisture) of the dye ink is vaporized. In this way, the printed recording medium W that has been dried is taken up by the take-up unit 21 together with the interleaving paper P.

  The feeding unit 18 is composed of a pair of left and right (Y-axis direction) T-shaped frames 32 fixed to the main body base 11 and a plurality of bar-shaped frames 33 passed between the pair of T-shaped frames 32. The feeding frame 31 and the pair of T-shaped frames 32 are supported so as to be slidable in the Y-axis direction, and slide on the two feeding-side rod bases 34 extending in the Y-axis direction and the two feeding-side rod bases 34. A pair of feed shaft protrusions 35 that are freely supported. The leading end portions of the feeding shaft projections 35 are formed in a truncated cone shape, and the pair of feeding shaft projections 35 are arranged in a roll-shaped recording manner by reciprocating each other corresponding to the width of the recording medium W. The recording medium W is horizontally supported by being fitted into the feeding core of the medium W.

  The pair of feeding shaft protrusions 35 are integrally moved left and right (in the width direction of the recording medium W) via two feeding-side rod bases 34 by a motor-driven width moving unit 36. When a position shift in the width direction of the recording medium W is detected by a meandering detection sensor 48 to be described later, the pair of feeding shaft protrusions 35 are moved slightly to the left and right. As a result, the ear (width end) of the wound recording medium W is shaped like a bamboo shoot, and when the recording medium W is axially displaced, the width of the recording medium W relative to the medium feeding mechanism 12 is increased. Misalignment, that is, the recording medium W is prevented from meandering (skewing) in the medium feeding mechanism 12.

  Further, a motor-driven rotation unit 37 is incorporated in one of the pair of feeding shaft protrusions 35, and the pair of feeding shaft protrusions 35 are fed and rotated by the rotating unit 37 so that the recording medium W is fed out. Yes. Further, below the feeding unit 18, a reflection type optical sensor 142 (see FIG. 2) that detects the presence or absence of the recording medium W fed from the feeding unit 18 is provided.

  In the present embodiment, there are a tension mode that feeds the recording medium W while applying a constant tension, and a slack mode that feeds the recording medium W with as little tension as possible, and mode switching is performed for each recording medium W. The tension mode and the slack mode can be switched by a GUI (Graphical User Interface) button on an operation screen (not shown) provided in the printing unit 5.

  The tension mode is for a normal fabric (recording medium W) having low stretchability. In this case, the control unit 7 configured by, for example, a personal computer applies a required tension to the recording medium W. Then, the rotation unit 37 is controlled so as to feed out toward the first roller 45. More specifically, the control unit 7 drives the rotation unit 37 so as to feed out the recording medium W during the feeding operation of the recording medium W by the medium feeding mechanism 12 by controlling the torque of the motor of the rotating unit 37, thereby feeding the medium. When the feeding of the recording medium W by the mechanism 12 is stopped, the rotation unit 37 is driven so that the recording medium W is slightly rewound. Thereby, the recording medium W is sent in a state where tension is applied to the recording medium W between the feeding unit 18 and the loosening unit 19.

  On the other hand, the slack mode is intended for a highly stretchable fabric (recording medium W) such as a stocking, for example. In this case, the control unit 7 once causes the recording medium W that has been fed out to slack downward. After that, the rotation unit 37 is controlled so as to be sent to the slack eliminating unit 19 (in FIG. 1, the recording medium W at the slack portion is indicated by a broken line). That is, the control unit 7 reduces the amount of slackness of the recording medium W as the recording medium W is fed by the medium feeding mechanism 12, and the optical sensor 142 provided below the feeding unit 18 uses the “ When “No” is detected, the rotation unit 37 is driven to rotate forward so as to feed out the recording medium W, and this increases the amount of slack. When the optical sensor 142 detects “Yes” of the recording medium W, the rotation unit 37 is driven. Stop. By controlling the slack amount, the recording medium W is fed in a state where the recording medium W between the feeding unit 18 and the slack eliminating unit 19 is appropriately slackened.

  The loosening unit 19 includes a pair of left and right (Y-axis direction) L-shaped frames 42 fixed to a side frame 62 of the medium feeding mechanism 12 to be described later, and a rod frame 43 passed between the pair of L-shaped frames 42.

The roller group 44 is arranged in the order of the first roller 45, the second roller 46, and the third roller 47 from the upstream side in the feeding direction so as to bend the feeding path 3 of the recording medium W fed from the feeding unit 18 at a plurality of positions. Each of the rollers is composed of a roller having a high coefficient of friction.

  The recording medium W fed from the feeding unit 18 reaches the second roller 46 and the third roller 47 so as to make a U-turn with the first roller 45. The second roller 46 and the third roller 47 are disposed close to each other in the vertical direction, and are rotatably supported by a pair of bearing portions 51 in which both end portions are integrally formed. Each bearing portion 51 is rotatably supported by the L-shaped frame 42, and the angle adjustment unit 52 that adjusts the upper and lower arrangement angles of the second roller 46 and the third roller 47 is provided on one bearing portion 51. Is incorporated.

  The recording medium W that passes through the second roller 46 and the third roller 47 is rerouted in an “S” shape, and the “S” curve is deformed and adjusted according to the type of the recording medium W, and the recording medium Appropriate tension can be applied for each W. As a result, the recording medium W is fed into the medium feeding mechanism 12 after partial slack and wrinkles are eliminated. Note that these rollers 45, 46, and 47 preferably have a medium-high shape so that a component force from the center to the outside acts on the recording medium W. A meandering detection sensor 48 is provided between the first roller 45 and the second roller 46.

  The medium feeding mechanism 12 is supported by the main body frame 61 having a pair of left and right (Y-axis direction) side frames 62 mounted and fixed on the main body base 11 and the pair of side frames 62, and is an endless transport belt. A belt conveyance unit 63 having 64 and a belt cleaning unit 65 disposed below the belt conveyance unit 63 are provided. Further, the medium feeding mechanism 12 includes a pressing roller 66 that faces the belt conveyance unit 63 from the upper side on the upstream side, and a separation roller 67 that is disposed obliquely above the belt conveyance unit 63 on the downstream side.

Each side frame 62 is appropriately provided with a notch for attaching the belt conveyance unit 63 and a notch for attaching the printing unit 5, and an opening for inspecting the belt cleaning unit 65 is formed. ing.

  The belt conveyance unit 63 includes a drive pulley 81 located on the downstream side in the feed direction, a driven pulley 82 located on the upstream side in the feed direction, and an endless conveyance belt 64 bridged between the drive pulley 81 and the driven pulley 82. ,have. The belt conveyance unit 63 is located in the vicinity of the driven pulley 82 and is located immediately below the printing unit 5 and the first guide plate 83 that guides the conveyance belt 64 and guides the conveyance belt 64. A second guide plate 84 and a third guide plate 85 that is located immediately above the support frame 72 and guides the travel of the conveyor belt 64 that wraps around the back side.

  The first guide plate 83 and the second guide plate 84 are bridged between the pair of side frames 62 in a state where the surfaces of the first guide plate 83 and the second guide plate 84 are flush with each other (the same horizontal plane). It also functions as a part. Further, the first guide plate 83 guides the conveyance belt 64 (upper side) immediately after being separated from the driven pulley 82 to run horizontally, and the second guide plate 84 is a conveyance belt 64 ( On the upper side) so that no slack occurs. Therefore, the conveyance belt 64 positioned immediately above the second guide plate 84 functions as a platen. Further, the third guide plate 85 guides the conveyor belt 64 that receives the thrust force by the belt cleaning unit 65 so as to press down (details will be described later).

  The drive pulley 81 and the driven pulley 82 are rotatably supported by a pair of side frames 62 via dedicated bearings, and a conveyance belt 64 intermittently travels on one shaft end of the drive pulley 81. A motor 86 is connected. The conveyance belt 64 is formed of a wide special belt having adhesiveness (adhesion treatment) on the outer peripheral surface (front surface), and a recording medium W is adhered and sent in the X-axis direction. As a result, the recording medium W is printed (intermittently fed) immediately below the printing unit 5 without causing any distortion.

  On the upper side of the driven pulley 82, a pressing roller 66 that sticks the recording medium W sent from the slack eliminating unit 19 to the transport belt 64 is disposed. The pressing roller 66 is rotatably supported at the distal ends of a pair of support arms 87 that are rotatably supported by the side frame 62. The pressing roller 66 has a predetermined elasticity and its own weight, and presses the recording medium W against the conveyance belt 64 immediately above the driven pulley 82 by its own weight. That is, the pressing roller 66 and the driven pulley 82 function as a nip roller with the conveyance belt 64 interposed therebetween, and continuously adhere the recording medium W to the traveling conveyance belt 64. An air cylinder 88 for rotating the support arm 87 is connected to an intermediate position between the support arms 87, and the pair of air cylinders 88 are driven synchronously so that the pressing roller 66 is moved from the conveyor belt 64. Torn apart.

  On the other hand, a separation roller 67 is disposed above the drive pulley 81 so that the recording medium W after printing is peeled off from the transport belt 64 and sent to the winding unit 6. The separation roller 67 is rotatably supported by a pair of sub frames 89 extending from the side frame 62. In this case, the separation roller 67 circulates the drive pulley 81 and relatively peels off the recording medium W from the conveyance belt 64 that wraps around to the back side. However, in actual operation, the peeling force from the conveyance belt 64 is The recording medium W differs depending on the type. For this reason, depending on the type of the recording medium W, there are a type in which the conveyance belt 64 starts to peel off at a position where the circulation starts and a case where the conveyance belt 64 starts to peel off at a position where the rotation has progressed to some extent. However, if the peeling point goes around to the back side, the recording medium W may be wound around the transport belt 64.

  Therefore, in the present embodiment, the position of the angle of the recording medium W sent from the transport belt 64 to the separation roller 67 is detected, and the winding unit 21 is driven to wind based on the detection result of the position detection, and then peeled off. This point is prevented from going around to the back side of the conveyor belt 64.

The wiper 99 comes into contact with the traveling conveyor belt 64 and scrapes the cleaning liquid. The cleaning liquid finally remaining on the conveyor belt 64 is wiped off with a waste cloth. The cleaning liquid is preferably circulated while filtering with the external tank.

  Since lint and dust adhere to the conveying belt 64 having adhesiveness over time, the belt cleaning unit 65 periodically cleans the conveying belt 64. In this cleaning operation, after the cleaning unit main body 93 is raised to a position where the rotary brush 97 and the wiper 99 come into contact with the conveyor belt 64, the conveyor belt 64 is run and the rotary brush 97 is rotated in the opposite direction to the running. Let At this time, the conveyor belt 64 is pressed by the third guide plate 85 and comes into contact with the rotating brush 97 while maintaining the horizontal posture. Thereby, the conveyance belt 64 (adhesive surface thereof) is continuously brushed and washed. In addition, it is preferable to perform an adhesion process on the transport belt 64 after cleaning so as to restore the adhesive force.
