One of the pair of rollers 10 is a driving roller connected to a driving source, and the other is a driven roller. The driving roller rotates and moves the endless belt 11 along the direction A in the figure.

  The upper surface of the endless belt 11 between the pair of rollers 10 is a placement surface 11a of a fabric (not shown), and a ground coating applied to the placement surface 11a using a liquid application / peeling device 2 described later. The fabric is brought into close contact with the film of the agent, and is conveyed in a state free from wrinkles as the endless belt 11 rotates.

  The liquid application / peeling device 2 extends above the placement surface 11a of the endless belt 11 along a direction orthogonal to the moving direction A of the placement surface 11a of the endless belt 11 (hereinafter referred to as the width direction). It has the stay member 20 spanned and the support member 21 attached to each end of the stay member 20 integrally.

  The stay member 20 is formed by a single prismatic rod-like body that is longer than the width of the endless belt 11 and has a length that protrudes on both sides of the endless belt 11.

  Each support member 21 is formed of a rectangular block body, and extends in the opposite direction to the moving direction A of the mounting surface 11a at both ends of the stay member 20 projecting from both sides of the endless belt 11, respectively. It is provided so as to protrude in parallel with the placement surface 11a. On the protruding side, one through hole 21a penetrating vertically is formed.

  In each of the through holes 21a, on both sides of the endless belt 11 in the recording medium conveyance device 1, a tip of a guide shaft 22 that is erected upward so as to extend in a direction perpendicular to the mounting surface 11a slides. Inserted as possible. Here, the guide shafts 22 are fixed to the support bases 12 provided on both sides of the recording medium transport device 1, and male screws 22a are engraved on the outer periphery thereof.

  The support member 21 can move up and down as the through hole 21 a moves up and down along the guide shaft 22. In order to make this vertical movement smoother, a cylindrical lubricating member 21b made of a material having a good sliding property including a lubricant such as a metal-based oil-free bearing is provided on the inner surface of the through hole 21a.

  Ascending and descending rotating members 23 are rotatably engaged with the male threads 22a on the outer periphery of the guide shaft 22, respectively. Each support member 21 is placed on the upper surface of the ascending / descending rotary member 23 with the end of the guide shaft 22 inserted into the through hole 21a, whereby the stay member 20 is placed on the placement surface of the endless belt 11. 11a is arranged so as to span over the width direction.

  A coating blade 24 for coating the surface of the endless belt 11 with a uniform thickness on the side surface of the stay member 20 facing in the direction opposite to the moving direction A of the mounting surface 11 a, and coating by the coating blade 24. A stripping blade 25 for stripping the applied adhesive from the surface of the endless belt 11 is provided.

  The coating blade 24 is a plate-like rigid body made of, for example, a metal plate such as stainless steel or a hard synthetic resin, and has a width similar to that of the endless belt 11 (length along the width direction of the endless belt 11). Yes. By being a plate-like rigid body, the thickness of the applied adhesive can be precisely defined.

  At the tip of the coating blade 24 (the end close to the placement surface 11a of the endless belt 11), the side surface on the downstream side in the moving direction A of the placement surface 11a is a tapered surface 24a. The application blade 24 has a tapered surface 24a on the side of the mounting surface 11a and protrudes from the stay member 20 toward the mounting surface 11a. It is fixed against.

  The peeling blade 25 is a plate-like elastic body made of, for example, urethane resin, and is formed to have the same width as the width of the coating blade 24 (the length along the width direction of the endless belt 11). The peeling blade 25 is attached along the coating blade 24 to the lower end side of the support plate 26 disposed on the surface of the coating blade 24 opposite to the surface fixed to the stay member 20. The tip of the peeling blade 25 (the end close to the placement surface 11a of the endless belt 11) protrudes closer to the placement surface 11a than the lower end of the support plate 26, and an appropriate number of screws 25a and pressing plates 25b The support plate 26 is fixed to the surface opposite to the coating blade 24.

  The support plate 26 has a plurality of elongated holes 26 a extending in the vertical direction at predetermined intervals in the width direction, and a plurality of guide pins 24 b protruding from the side surfaces of the coating blade 24 are fitted therein. Thus, the coating blade 24 is supported on the side surface of the coating blade 24 so as to be movable with respect to the coating blade 24 along the vertical direction with a stroke of the length of the long hole 26a.

  A fixing knob 26b for fixing the support plate 26 so as not to move at a predetermined position with respect to the side surface of the coating blade 24 is inserted into one of the plurality of long holes 26a (here, two). Yes. On the side surface of the coating blade 24 corresponding to the long hole 26a into which the fixing knob 26b is inserted, a female screw into which the screw portion at the tip of the fixing knob 26b is screwed is engraved. By tightening the fixing knob 26b, The support plate 26 is sandwiched between the application blade 24 and fixed at that position, and the fixing knob 26b is loosened, whereby the support plate 26 is moved up and down with respect to the application blade 24 by the stroke of the length of the long hole 26a. It is possible to move to.

  When the support plate 26 is lowered so that the guide pin 24b is positioned at the upper end of the long hole 26a, the upper end of the support plate 26 is in a state coincident with the upper end of the coating blade 24 (FIG. 3A). In this state, the tip of the peeling blade 25 attached to the support plate 26 protrudes below the tip of the coating blade 24. On the other hand, when the support plate 26 is raised so that the guide pin 24b is positioned at the lower end of the long hole 26a, the upper end of the support plate 26 protrudes above the upper end of the coating blade 24 (FIG. 3B). )). In this state, the tip of the coating blade 24 protrudes higher than the tip of the peeling blade 25.

  Two positioning holes 26c and 26d are formed in the support plate 26 so as to penetrate in the vertical direction with an interval corresponding to the vertical length of the long hole 26a, and a positioning pin 26e is inserted into one of them. . The positioning pin 26e is inserted into one of the positioning holes 26c and 26d, thereby engaging and supporting one engagement hole 24c (FIGS. 4 and 5) formed on the side surface of the coating blade 24. The plate 26 is positioned at a height position where the guide pin 24a is raised or lowered to the position of either the upper end or the lower end of the long hole 26a, and the height position of the support plate 26, that is, the placement surface 11a of the peeling blade 25 is positioned. The height position with respect to is changed.

  The guide pin 24b, the engagement hole 24c, the long hole 26a, the fixing knob 26b, the positioning holes 26c and 26d, and the positioning pin 26e in the present embodiment constitute a switching mechanism in the present invention.

  The support plate 26 is fixed at that position by tightening the fixing knob 26b in a state where the position of the support plate 26 is positioned by the positioning pin 26e, whereby the vertical position of the peeling blade 25 is determined.

  Leakage-preventing members 27 for restricting the application width of the adhesive at the time of application or the release width of the adhesive at the time of peeling are respectively provided at portions close to both ends in the width direction of the coating blade 24 and the peeling blade 25. Are detachably provided.

  The leakage preventing member 27 is a plate-like elastic body made of, for example, a rectangular urethane resin. A mounting plate portion 27a having a pair of plate-like portions is attached to the stay member 20 corresponding to both ends in the width direction of the coating blade 24 and the peeling blade 25, and the leakage preventing member 27 is connected to the mounting plate 27a. The tip 27 (the end close to the placement surface 11a of the endless belt 11) is sandwiched between the pair of plate-like portions of the portion 27a, and on the same side as the coating blade 24 of the stay member 20, the moving direction of the placement surface 11a It is mounted so as to be arranged in parallel with A. Accordingly, the coating blade 24 and the peeling blade 25 are disposed so as to be sandwiched between the two leakage prevention members 27.

  The leak-proof member 27 is mounted in the mounting plate portion 27a so that the tip is located at the same position as the tip of the coating blade 24 when the adhesive is applied, and when the adhesive is peeled off, The mounting plate portion 27a is mounted so that the tip is in the same position as the tip of the peeling blade 25.

  Further, reference numeral 28 in FIG. 1 is a handle provided on each support member 28, and reference numeral 29 is a handle provided on the support plate 26.

  Next, a method for applying a coating agent to the surface of the endless belt 11 and a method for peeling off using the liquid applying / peeling device 2 will be described.

  When applying the adhesive to the surface of the endless belt 11, the blade to be used is the application blade 24. First, the support plate 26 is held by the handle 29 so that the guide pin 24b is positioned at the lower end of the long hole 26a. , The positioning pin 26e is inserted into the lower positioning hole 26d and engaged with the engaging hole 24c of the coating blade 24, and then the fixing knob 26b is tightened to fix the support plate 26 in that position. . As a result, the tip of the coating blade 24 protrudes downward from the tip of the peeling blade 25 (FIGS. 3B and 4).

  At this time, each of the attachment plate portions 27a is mounted with the leakage preventing member 27 so that the tip thereof is at the same position as the tip of the coating blade 24.

  Next, the elevating rotary member 23 is lowered along the guide shaft 22 by rotating the elevating rotary member 23 in a predetermined direction. Since the support member 21 is placed on the upper surface of the ascending / descending rotary member 23, the support member 21 descends as the ascending / descending rotary member 23 descends, thereby placing the stay member 20 integral with the support member 21. It descends toward the surface 11a.

  Since the coating blade 24 is fixed to the stay member 20, the coating blade 24 is lowered together with the stay member 20, so that the lifting and lowering rotating member 23 is rotated until the tip of the coating blade 24 abuts uniformly on the placement surface 11 a in the width direction. To lower each. At this time, the tip of each leakage prevention member 27 also abuts on the placement surface 11a.

  Next, an appropriate amount of the adhesive X from the container 100 storing the adhesive to the upstream side in the movement direction of the endless belt 11 relative to the liquid application / separation device 2 is substantially equal to the width direction of the endless belt 11. The endless belt 11 is driven to rotate in the moving direction A for many turns. As a result, the upholstery is smoothed by the tip of the coating blade 24, and the upholstery film Xa is formed on the surface of the endless belt 11 (FIG. 4).

  Although the adhesive spreads in the width direction of the endless belt 11, the leakage preventing member 27 restricts the spread of the adhesive in the width direction, so that the film Xa falls within a predetermined width defined by the leakage preventing members 27. Is formed.

  Thereafter, the application state of the adhesive is checked, and the rotary member 23 for raising and lowering is rotated each time in the opposite direction while adding the adhesive as necessary, thereby gradually raising the tip of the application blade 24. Gradually away from the mounting surface 11a.

  As the tip of the coating blade 24 moves away from the mounting surface 11 a, the adhesive applied at the tip of the coating blade 24 decreases, and eventually the coating Xa of the coating does not contact the tip of the coating blade 24. As a result, a film Xa of a paste having a predetermined thickness is applied and formed on the surface of the endless belt 11.

  Since the thickness of the film Xa is determined by the amount of the adhesive and the position of the tip of the coating blade 24, it can be controlled freely and easily by adjusting the amount of the coating and the position of the tip of the coating blade 24. it can. In addition, since the applied adhesive is leveled over the width direction of the endless belt 11 by the coating blade 24, the film Xa having a uniform thickness can be formed in the width direction.

  When the application of the adhesive is completed, the leakage preventing member 27 is removed, the lifting rotary member 23 is further raised, and the tip of the coating blade 24 and the placement surface 11a are separated greatly.

  If the tip of the coating blade 24 is far away from the placement surface 11a, the fabric transport path is secured, and the fabric can then be transported while sticking to the placement surface 11a. Thereafter, the liquid application / peeling device 2 is not necessary, and the support member 21 may be detached from the guide shaft 22 by holding the handle 28 and may be detached from the recording medium conveying device 1. By removing the liquid application / peeling device 2, visual confirmation of the transport state of the fabric is facilitated.

  On the other hand, when peeling the adhesive applied to the surface of the endless belt 11, the blade to be used is the peeling blade 25. First, the handle 29 is set so that the guide pin 24b is at the upper end position of the long hole 26a. The support plate 26 is lowered, and the positioning pin 26e is inserted into the upper positioning hole 26c and engaged with the engagement hole 24c of the coating blade 24, and then the fixing knob 26b is tightened, whereby the support plate 26 is Fix in position. As a result, the tip of the peeling blade 25 protrudes downward from the tip of the coating blade 24 (FIGS. 3A and 5).

  At this time, each of the attachment plate portions 27a is mounted with the leakage preventing member 27 so that the tip is in the same position as the tip of the peeling blade 25.

  Next, by rotating the elevating rotary member 23 in a predetermined direction, the elevating rotary member 23 is lowered along the guide shaft 22 and the stay member 20 is lowered toward the placement surface 11a.

  The peeling blade 25 is fixed to the stay member 20 via the coating blade 24 and descends together with the stay member 20. Therefore, the lifting and lowering rotating member 23 is moved until the tip of the peeling blade 25 abuts uniformly on the placement surface 11 a in the width direction. Rotate to lower. At this time, the tip of each leakage prevention member 27 also abuts on the placement surface 11a.

  Next, the release agent Y is moved from the container 200 for storing the release agent for melting the adhesive to the upstream side in the moving direction of the endless belt 11 with respect to the liquid application / peeling device 2, and is almost in the width direction of the endless belt 11. An appropriate amount is poured so as to be uniform, and the endless belt 11 is driven to rotate in the moving direction A many times. Accordingly, the film Xa of the adhesive is scraped off by the tip of the peeling blade 25 while being melted by the peeling agent Y (FIG. 5).

  The adhesive that is scraped off by the peeling blade 25 spreads in the width direction of the endless belt 11, but the leakage preventing member 27 restricts the spread in the width direction of the adhesive that has been scraped off.

  Thereafter, when the film Xa of the adhesive is removed, each of the lifting rotary members 23 is rotated in the opposite direction and gradually raised, thereby separating the tip of the peeling blade 25 from the placement surface 11a.

  When the stripping agent has been peeled off, the elevating rotary member 23 is further raised, and the tip of the coating blade 24 and the mounting surface 11a are separated greatly, or each support member is held by the handle 28. By removing 21 from the guide shaft 22, it is removed from the recording medium conveying apparatus 1.

  As described above, the liquid coating / peeling device 2 can perform coating and peeling of the adhesive on the surface of the endless belt 11 with a single device, and therefore, a device having two functions can be provided. It can be installed only in the installation space. For this reason, the structure of the recording medium conveying apparatus 1 does not become complicated.

  In addition, since the liquid application / separation device 2 can be easily detached simply by removing it from the guide shaft 22, it can be attached only when it is used, so that it becomes an obstacle when the recording medium conveying device 1 is operated. Nor.

  In the above embodiment, the coating blade 24 is fixed to the stay member 20 side, and the peeling blade 25 is attached to the coating blade 24 via the support plate 26. By doing so, there is no fear that the old adhesive that is scraped off by the peeling blade 25 and gradually accumulates at the tip of the peeling blade 25 will adhere to the coating blade 24 when the adhesive is peeled off. It is.

  However, if a large stroke for parallel translation can be taken, the peeling blade 25 (support plate 26) side is fixed to the stay member 20 and the coating blade 24 is attached to the support plate 26 as shown in FIG. You may do it.

  6A shows a state where the tip of the coating blade 24 protrudes downward from the tip of the peeling blade 25, and FIG. 6B shows a state where the tip of the peeling blade 25 protrudes below the tip of the coating blade 24. It shows the state that was made to. In this case, a long hole 24d is formed in the coating blade 24, engaged with a guide pin 26f protruding from the side surface of the support plate 26, and configured to be movable in parallel with the support plate 26 in the vertical direction. 24, two positioning holes 24e and 24f are provided on the upper and lower sides. A positioning pin 24g is selectively inserted into the positioning holes 24e and 24f so as to engage with the engaging holes 26g provided in the supporting plate 26. The height position with respect to 26 can be switched. The application blade 24 may be fixed using a fixing knob (not shown) similar to the fixing knob 26b.

  As shown in FIG. 7, the ink jet recording apparatus P1 is mounted above the mounting surface 11a of the endless belt 11 of the recording medium transport apparatus 1 to which the above-described liquid coating / peeling apparatus 2 is mounted or can be mounted. A recording head 3 is arranged. The recording head 3 is in close contact with the adhesive applied to the mounting surface 11a by the liquid application / peeling device 2 by discharging ink from a number of nozzles formed on the nozzle surface facing the mounting surface 11a. A predetermined image is recorded on the surface of a recording medium such as a cloth (not shown) conveyed while being conveyed.

  Further, as shown in FIG. 8, the means for conveying the recording medium may be a recording medium conveying device 4 using a rotating roller 40 other than the endless belt. The surface 40a of the rotating roller 40 serves as a recording medium mounting surface. A recording medium such as a cloth is wound around the surface 40a, and the recording medium is conveyed in the A direction by its own rotation.

  The liquid applying / peeling device 2 can be mounted so as to be close to the surface 40a of the rotating roller 40, and the surface coating agent is applied to or applied to the surface 40a of the rotating roller 40 by the same method as described above. Remove the adhesive.

  As shown in FIG. 8, in the ink jet recording apparatus P <b> 2 using the rotating roller, the recording head 3 is disposed so as to be close to the surface 40 a of the rotating roller 40 of the recording medium transport apparatus 4. The recording head 3 is in close contact with the adhesive applied to the surface 40a by the liquid applying / peeling device 2 by ejecting ink from a number of nozzles formed on the nozzle surface facing the surface 40a of the rotating roller 40. A predetermined image is recorded on the surface of a recording medium such as a cloth (not shown) conveyed while being conveyed.
