An auxiliary unit base that supports the medium feeding auxiliary unit, and the main unit base and the auxiliary unit base are configured to be detachable from each other, and the auxiliary unit base is configured as a main unit base. It is characterized by being made of a material lighter than the material.
In this case, it is preferable that the auxiliary machine base is configured by combining extruded aluminum members.

The winding machine base of the present invention is configured to be detachable from a main body base that supports a printing apparatus main body that prints on the recording medium while feeding the recording medium, and winds up the recording medium printed by the printing apparatus main body. A winding support portion for supporting the winding portion is provided, and the winding support portion is made of a material that is lighter than the material of the main unit base.
In this case, it is preferable that the aluminum extruded shape material is combined.

According to this configuration, the auxiliary unit base (winding unit base) is made of a material that is lighter than the main unit base, such as an extruded aluminum material. The auxiliary unit base (winding unit base) can be moved with a relatively light force. For this reason, it is possible to easily attach and detach the auxiliary unit base with respect to the main unit base.
As the auxiliary machine base, in addition to the take-up machine base that supports the take-up part that winds up the recording medium printed by the printing apparatus main body, for example, the feeding out of the recording medium toward the printing apparatus main body is performed. A machine base for a feeding section that supports the section can be mentioned.

  In the recording apparatus, the recording medium is a fabric, and the medium feeding auxiliary unit is a winding unit that winds up the recording medium printed by the printing apparatus main body, supported by the auxiliary unit machine base, and the winding unit. The fabric facing the fabric is in sliding contact with the heater part having a heat radiating surface for heating the cloth for drying, and supported by the auxiliary machine base.

It is the figure which looked at the machine base for winding parts in an inkjet recording device from the left side with respect to a feed direction. It is the figure which looked at the machine stand for main bodies in an inkjet recording device from the feed direction downstream side.

  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 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 feed direction of the recording medium, which is a fabric, is the X axis direction, the direction orthogonal to the X axis direction is the Y axis direction, and the direction orthogonal to the X axis direction and the Y axis direction is the Z axis. Specify the 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 both supported and supported by the two feeding-side rod bases 34 extending in the Y-axis direction and the two feeding-side rod bases 34 so as to be slidable. A pair of feeding shaft protrusions 35. 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 core of the medium W.

  Each of the pair of feeding shaft projections 35 incorporates a motor-driven width moving unit 36. When the axial displacement of the recording medium W has occurred (detection), the pair of feeding shaft projections 35 is replaced with two. The recording medium W is slightly moved on the feeding-side rod base 34 to prevent the recording medium W from being displaced in the width direction with respect to the medium feeding mechanism 12, that is, the recording medium W is meandering (skewed) 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. 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 is for a normal fabric (recording medium W) having low stretchability. In this case, a load (tension) is acquired in the control system of the rotation unit 37, and this load is a predetermined value. The rotation unit 37 is controlled so as to be a value.
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, after the recording medium W fed out is once slackened downward (FIG. 1). Then, control is performed so as to be sent to the slack eliminating unit 19. Specifically, the lower end position of the slackened recording medium W is detected, and when the lower end position exceeds a predetermined position and the slackness increases, the feeding operation of the recording medium W by the rotating unit 37 is stopped. ing.

  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. And a roller group 44 that is rotatably supported by a pair of L-shaped frames 42. The roller group 44 includes a first roller 45, a second roller 46, a third roller 47, and a fourth roller 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 locations. The rollers 48 are arranged in this order.

  The first roller 45 is composed of a roller having a high friction coefficient, and is placed on a pair of inclined blocks 49 whose both ends are attached to the inside of each L-shaped frame 42. The recording medium W in the state where the upstream side is slackened is rerouted diagonally outward toward the second roller 46 at the portion of the first roller 45. When the recording medium W is pulled (feeded) by the intermittent feeding of the medium feeding mechanism 12, the first roller 45 moves up the pair of inclined blocks 49 by the frictional force between the recording medium W and the first roller 45. Moving. When the feeding of the recording medium W is stopped, the first roller 45 returns to the original position by moving down the pair of inclined blocks 49 by its own weight. As a result, an appropriate tension is applied to the recording medium W being fed, and the intermittent feed shock is absorbed.

  The recording medium W that has passed through the first roller 45 reaches the third roller 47 and the fourth roller 48 in a U-turn by the second roller 46. The third roller 47 and the fourth roller 48 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 an angle adjustment unit 52 that adjusts the upper and lower arrangement angles of the third roller 47 and the fourth roller 48 is provided on one bearing portion 51. Is incorporated.

  The recording medium W passing through the third roller 47 and the fourth roller 48 is changed in path to an “S” shape, and this “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, 47, and 48 preferably have a medium-high shape so that a component force from the center to the outside acts on the recording medium W.

  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.

The main body frame 61 is located between the pair of connection frames 71 and has a support frame 72 that connects the pair of side frames 62 and supports the belt cleaning unit 65. 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, there are a recording medium W that starts to peel off at a position where the conveyance belt 64 starts to circulate, and a recording belt that starts to peel off at a position where the circulation 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 continuously, the conveying belt 64 is periodically cleaned by the belt cleaning unit 65. 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.

Furthermore, four casters 144 distributed in the lower part are attached to the winding machine base 24 (lower horizontal frame part 122).

  On the other hand, as shown in FIG. 3, the machine base 11 has a pair of left and right hole plates 145 attached to the lower end portion on the winding unit machine base 24 side. Each hole plate 145 has a positioning hole 146 with which the positioning pin 142 is engaged. Further, the main machine base 11 is provided with four support legs 147 with adjusting bolts distributed in the lower part.

  The main unit base 11 and the winding unit base 24 configured as described above are configured so that the winding unit base 24 can be separated from the main unit base 11 as necessary. For example, when performing maintenance of the medium feeding mechanism 12 supported by the main body base 11, by separating the winding unit base 24 on the downstream side of the medium feeding mechanism 12 from the main body base 11, An operator can easily access the belt conveyance unit 63 and the belt cleaning unit 65 of the medium feeding mechanism 12 from the downstream side of the medium feeding mechanism 12, and the maintenance of the medium feeding mechanism 12 can be easily performed. Further, when moving the inkjet recording apparatus 1 such as when the apparatus is carried in, separating the winding unit machine base 24 from the main body machine base 11 shortens the overall length of the apparatus and improves handling. . Further, when the slip sheet P is pulled out from the slip sheet unit 22 and set between the recording medium W and the heat radiating surface 125a of the heater unit 23, a hand is inserted from the left and right sides of the winder unit base 24. Is difficult (particularly, when the width of the recording medium W is narrow and accordingly a narrow slip sheet P is used), the take-up unit base 24 is separated from the main unit base 11. By doing so, the operator can easily access the slip sheet unit 22 and the heater unit 23 from the upstream side of the winder unit base 24, and this work can be easily performed.

  Further, after these maintenance and movement are completed, the winding unit base 24 is connected to the main body base 11 in a positioning state by engaging the positioning pins 142 and the positioning holes 146. Can do. Thereby, the winding unit 6 is positioned with respect to the medium feeding mechanism 12, and the recording medium W can be appropriately wound without winding deviation. In addition, as described above, the winding unit machine base 24 is constructed by combining aluminum extruded shapes, and is lighter than the main body machine base 11 made of steel. However, the attachment / detachment / positioning operation of the winding unit base 24 with respect to the main body base 11 can be easily performed. In addition to aluminum, examples of the material constituting the winding unit machine base 24 include light metal, resin, and wood.

  Further, since positioning is performed by the positioning pins 142 extending in the attaching / detaching direction, the operator positions the positioning hole 146 with respect to the main body machine base 11 in accordance with the movement of the winding unit base 24 in the attaching / detaching direction. The pin 142 can be disengaged. Thereby, positioning with the machine base 11 for main bodies and the machine base 24 for winding parts can be performed rapidly. In the present embodiment, the positioning pin 142 is provided on the winding unit machine base 24 side and the positioning hole 146 is provided on the main body machine base 11 side, but this may be reversed.

  As described above, according to the ink jet recording apparatus 1 of the present embodiment, the attaching / detaching work of the winder unit base 24 to the main body base 11 can be easily performed. The feeding unit 18 may also be configured to include a feeding unit base that is detachable from the main body base 11 and made of a lighter material than the main body base 11. Also in this case, the work for attaching and detaching the feeding unit base to the main body base 11 can be easily performed. The present invention can also be applied to so-called line printers.
