Description

Technical Field

[0001] The present invention relates to a recording device. Background Art

[0002] As an example of this type of device, a heating device and a medium processing device described in Patent Document 1 can be cited. In Patent Document 1, the following is described.

[0003] The heating device 40 includes a heating unit 41 for heating a medium 99, a housing 42 for housing the heating unit 41, a flow path 43 for gas to flow, and a blower 44 for blowing the gas. The flow path 43 has a flow inlet 53 for taking in gas into the flow path 43 and a blowout port 54 for blowing out the gas in the flow path 43. The flow inlet 53 and the blowout port 54 open toward the support surface 23. Since the gas inside the device heated by the heating unit 41 flows along the support surface 23 to the opposite side of the side where the recording unit 15 is located, the concern that the heated gas flows toward the recording unit 15 can be reduced.

[0004] Although the heater path is inclined in the above-described conventional example, in order to miniaturize the device, the heater path may sometimes be made vertical. In addition, in order to enable a user to easily access and handle the wound medium, there is a case where the winding position of the winding unit is arranged on the front side.

[0005] When such a configuration is adopted, the heated air stays around below the heater and above the winding unit. In the above-described conventional example, since the flow inlet opens toward the support surface, that is, the direction of the medium, the stagnant air flows into the heater. Therefore, it is difficult to take in fresh air from the outside into the heater, and thus the suppression of the temperature rise of the surface of the heater exterior component and the dryness of the medium are reduced.

[0013] Hereinafter, the present invention will be described schematically first.

[0014] The first mode of the recording apparatus according to the present invention includes: a conveying unit that conveys a medium in a conveying direction of a conveying path; a recording unit that records an image on the medium conveyed by the conveying unit; a heating unit that heats the recorded medium conveyed in a first direction in the conveying direction; a downstream conveying path member that constitutes the conveying path at a position downstream in the conveying direction compared to the heating unit, and the downstream conveying path member is disposed at a position overlapping the heating unit when viewed from above in the first direction. The heating unit includes: an air flow path body; a heater that is disposed outside the air flow path body and heats the medium; an air inlet for sucking air outside the air flow path body into the inside of the air flow path body; an air outlet for blowing the air inside the air flow path body toward the medium outside the air flow path body; a fan that is disposed inside the air flow path body and sends air from the air inlet to the air outlet. The air inlet is provided in a second direction intersecting the first direction of the air flow path body and at a position on the opposite side of the side facing the medium conveyed in the first direction.

[0015] According to this mode, the air inlet is provided in a second direction intersecting the first direction of the air flow path body and at a position on the opposite side of the side facing the medium. Thus, although the downstream conveying path member is disposed at a position downstream in the conveying direction compared to the heating unit, the air inlet is provided so as to be separated from the downstream conveying path member. In other words, the air inlet can take in fresh air into the inside of the air flow path body from another space separated from the space where the heated air staying near the downstream conveying path member exists. Therefore, it is possible to suppress a decrease in the dryness of the medium. In addition, it is possible to suppress a rise in the surface temperature of the air flow path body.

[0016] The second mode of the recording apparatus according to the present invention is a mode subordinate to the first mode, and is characterized in that the air flow path body has: a first flow path body that extends along the first direction and has the air inlet; a second flow path body that is connected to an upstream end portion in the conveying direction of the first flow path body, extends in the second direction, and has the air outlet, and the heater is provided at a position facing both the first flow path body and the second flow path body.

[0017] According to this aspect, the heater is disposed at a position facing both the first flow channel body and the second flow channel body. In other words, in the heating portion constituted by the heater and the air flow channel body, the heater and the second flow channel body are overlapped and disposed when viewed from the first direction. Thereby, an increase in the overall thickness of the heating portion can be suppressed.

[0018] A third aspect of the recording apparatus according to the present invention is an aspect subordinate to the second aspect, characterized in that the fan is disposed inside the second flow channel body and in a region that becomes the inside of the first flow channel body.

[0019] According to this aspect, the fan is disposed inside the second flow channel body and in a region that becomes the inside of the first flow channel body. In other words, the fan is disposed so as to straddle the two regions of the first flow channel body and the second flow channel body. Thereby, even if the fan is a component of a size that cannot be disposed inside the first flow channel body, since a part of the fan is disposed in the region of the second flow channel body, an increase in the size of the entire heating portion can be suppressed.

[0020] A fourth aspect of the recording apparatus according to the present invention is an aspect subordinate to the second aspect, characterized in that the air inlet is provided at a position at an end portion of the first flow channel body on the side opposite to the second flow channel body.

[0021] Moreover, this aspect can also be subordinate to the third aspect.

[0022] According to this aspect, the air inlet is provided at a position at an end portion of the first flow channel body on the side opposite to the second flow channel body. Thereby, fresh external air is sucked in from the air inlet at this position, flows across the entire length of the first flow channel body, and reaches inside the second flow channel body. Then, it flows through the inside of the second flow channel body and is blown out from the air outlet. Therefore, by bringing the first flow channel body and the second flow channel body into contact with the fresh external air, an increase in the temperature of the entire surface of the air flow channel body can be effectively suppressed.

[0023] In addition, since the distance between the air inlet and the fan can be ensured to be large, the suction loss caused by a large bend in the portion that becomes the suction portion of the external air can be reduced.

[0024] The fifth mode of the recording apparatus according to the present invention is a mode subordinate to the third mode, characterized in that the direction in which the fan blows out air is different from the direction in which the air is blown out from the blowout port, and a wall portion is provided in the region between the fan and the blowout port, and the wall portion guides the direction of the air blown out from the fan toward the position where the blowout port is arranged.

[0025] According to this mode, a wall portion is provided between the fan and the blowout port, and the wall portion guides the direction of the air blown out from the fan toward the position where the blowout port is arranged. Thus, even if the direction in which the fan blows out air is different from the direction in which the air is blown out from the blowout port, since the air blown out from the fan first collides with the wall portion, the air can also be guided to the blowout port while diffusing in the width direction intersecting the conveying direction by passing through the wall portion.

[0026] The sixth mode of the recording apparatus according to the present invention is a mode subordinate to the fifth mode, characterized in that a plurality of the blowout ports are arranged in the width direction of the conveying path intersecting the conveying direction.

[0027] According to this mode, since a plurality of the blowout ports are arranged in the width direction of the conveying path intersecting the conveying direction, air can be blown out uniformly in the width direction.

[0028] The seventh mode of the recording apparatus according to the present invention is a mode subordinate to the first mode, characterized in that the first direction is the vertical direction.

[0029] In addition, this mode can also be subordinate to any one of the second mode to the sixth mode.

[0030] According to this mode, since the first direction is the vertical direction, miniaturization of the recording apparatus in the front-rear direction can be promoted.

[0031] Embodiment

[0032] Hereinafter, regarding the embodiment of the recording apparatus according to the present invention, based on Figures 1 to 5 it will be described.

[0033] In the following description, as shown in the respective figures, three mutually orthogonal axes are respectively set as the X-axis, Y-axis, and Z-axis. The directions indicated by the arrow marks of the three axes (X, Y, Z) are the + directions of the respective directions, and the opposite directions are the - directions. The Z-axis direction corresponds to the vertical direction, i.e., the direction in which gravity acts. The +Z direction represents vertically upward, and the -Z direction represents vertically downward. The X-axis direction and the Y-axis direction correspond to the horizontal direction. The +Y direction represents the front direction of the recording device, and the -Y direction represents the rear direction of the device. The +X direction represents the right direction of the device, and the -X direction represents the left direction of the device.

[0034] Embodiment 1

[0035] The recording device of Embodiment 1 is a recording device called a digital printing press for textiles, where the medium is textiles. This recording device applies an appropriate tension to the textiles by a conveying method called the roll-to-reel conveying method and sets the recording area in a floating state. The recorded medium is heated and dried by a heating unit disposed on the conveying path and is wound up by a winding unit.

[0036] Hereinafter, the recording device of this embodiment will be specifically described.

[0037] As Figures 1 to 5 shown, the recording device 1 of this embodiment includes: a conveying unit 4 that conveys a medium 2 such as textiles in the conveying direction F of the conveying path 3; a recording unit 5 that records an image on the medium 2 conveyed by the conveying unit 4; and a heating unit 6 that heats the recorded medium 2 conveyed in the first direction D1 in the conveying direction F. As Figure 2 shown, in this embodiment, the first direction D1 is the vertical direction (-Z direction).

[0038] At a position downstream of the heating unit 6 in the conveying direction F, a downstream conveying path member 7 that constitutes the downstream position of the conveying path 3 is disposed. As Figure 2 shown, the downstream conveying path member 7 is disposed at a position that overlaps the heating unit 6 when viewed from above in the first direction D1.

[0039] As Figure 2 shown, the heating unit 6 includes an air flow path body 8 and a heater 9. The heater 9 is disposed outside the air flow path body 8. The heater 9 is in a rod shape and includes a reflector 21 and a wire mesh 22. The air flow path body 8 has an air inlet 10 for sucking external air into the interior of the air flow path body 8 ( Figure 1 、 Figure 2) and a blowout port 11 for blowing the air inside the air flow channel body 8 toward the medium 2 outside the air flow channel body 8. Further, a fan 12 is disposed inside the air flow channel body 8, and the fan 12 conveys air from the air inlet 10 to the blowout port 11. That is, the fan 21 generates a flow of air from the air inlet 10 toward the blowout port 11. The symbol K represents the flow direction of the air.

[0040] Moreover, the air inlet 10 is provided at a portion on the air flow channel body 8 in the second direction D2 intersecting the first direction D1 and on the opposite side (+Y side) of the side opposite to the medium 2 conveyed in the first direction D1 (-Y side).

[0041] Transport path, transport unit, downstream transport path component

[0042] As Figure 2 shown, in the present embodiment, the reel body R1 of the medium 2 is rotatably supported by the reel shaft 35 of the unwinding unit 31. The medium 2 pulled out from the reel body R1 is conveyed through the recording range of the recording unit 5 by the intermediate rollers 33 and 38 constituting the transport path 3. Further, it is conveyed through the heating range of the heating unit 6 by the intermediate roller 38 and the guide rod 34. The medium 2 that has passed through the guide rod 34 is wound around the reel body R2 rotatably supported by the reel shaft 36 of the winding unit 32. The reel shaft 36 is driven to rotate by receiving rotational power from a drive source (not shown), so that the reel body R2 rotates in the winding direction.

[0043] In the present embodiment, the transport unit 4 is constituted by the reel body R2 of the winding unit 32, the guide rod 34, the intermediate roller 38, the intermediate roller 33, and the reel body R1 of the unwinding unit 31. In addition, the downstream transport path component 7 is constituted by the guide rod 34 disposed downstream in the transport direction F of the heating unit 6 and further by the winding unit 32.

[0044] Air flow channel body

[0045] As Figure 3 shown in the enlarged view, in the present embodiment, the air flow channel body 8 has a first flow channel body 81 and a second flow channel body 82. The first flow channel body 81 extends along the first direction D1 and has the air inlet 10. The second flow channel body 82 is connected to the upstream end portion 13 on the transport direction F side of the first flow channel body 81, extends in the second direction D2, and has a structure with the blowout port 11. The second flow channel body 82 is connected to the internal space at the upstream end portion 13 of the first flow channel body 81 and at a portion on the side opposite to the transport path 3. Thus, the air flowing in from the air inlet 10 flows in the direction K and flows out to the outside from the blowout port 11.

[0046] The heater 9 is disposed at a position facing both the first flow channel body 81 and the second flow channel body 82. In other words, the heater 9 is arranged within the range of the length of the second flow channel body 82 in the Y-axis direction. Here, two heaters 9 are provided along the conveying path 3.

[0047] At the lower end portion of the first flow channel body 81, a cover 20 ([[]] Figure 3 ) that forms a part of the appearance of the heating unit 6 is provided.

[0048] Fan, wall portion

[0049] In the present embodiment, the fan 12 is disposed inside the second flow channel body 82 and in a region that becomes the inside of the first flow channel body 81. As Figure 3 shown, the direction Fa in which the fan 12 discharges air and the blowing direction Fb in which the air is blown out from the blowout port 11 are different.

[0050] Therefore, in the present embodiment, a wall portion 15 is provided in the region between the fan 12 and the blowout port 11. Specifically, the wall portion 15 is a U-shaped plate provided on the upper surface of the fan 12, and is provided in such a manner that the open side of the U-shape faces the direction of the blowout port 11. As indicated by the arrow A, the wall portion 15 is configured to guide the direction Fa in which the fan 12 discharges air toward the position where the blowout port 11 is disposed.

[0051] As Figure 5 shown, in the present embodiment, a plurality of blowout ports 11 are arranged in the width direction (X-axis direction) of the conveying path.

[0052] Air inlet

[0053] As Figure 3 shown, in the present embodiment, the air inlet 10 is provided at the position of the end portion 14 of the first flow channel body 81 on the side opposite to the second flow channel body 82. In other words, the air inlet 10 is provided at the portion farthest from the fan 12. With this configuration, the air sucked in from the air inlet 10 by the suction force of the fan 12 flows within the first flow channel body 81 across the entire length in the vertical direction (+Z direction) and reaches the fan 12.

[0054] As Figure 1 shown, the air inlet 10 is located on the front side of the recording device 1, and three air inlets 10 are provided in the width direction (X-axis direction). Of course, it is not limited to three, and it may be configured with two or four or more. Although not shown, the air inlet 10 is formed of a net body or a lattice body with a small mesh. The winding portion 32 is also located on the front side of the recording device 1. In Figure 1Only the winding shaft 36 of the winding section 32 is shown, and the illustration of the drum body R2 is omitted.

[0055] Modified example

[0056] Although in the above description, it is described that the air inlet 10 is provided at the position of the end portion 14 of the first flow channel body 81 on the side opposite to the second flow channel body 82, it is not limited to this position. For example, it may also be arranged at a position on the lower end surface in the -Z direction end surface of the first flow channel body 81 and separated from the conveying path 3.

[0057] Description of the effects of Embodiment 1

[0058] (1) In the present embodiment, the air inlet 10 is provided in the second direction D2 intersecting the first direction D1 of the air flow channel body 8 and at a position on the opposite side of the side facing the medium 2. Thus, although downstream conveying path components 7 such as the guide rod 34 and the drum body R2 are arranged at positions downstream in the conveying direction F compared to the heating section 6, the air inlet 10 is arranged so as to be separated from the downstream conveying path components 7. In other words, the air inlet 10 can take in fresh air into the interior of the air flow channel body 8 from another space separated from the space where the heated air staying near the downstream conveying path components 7 exists. Therefore, it is possible to suppress the reduction of the dryness of the medium 2. In addition, it is possible to suppress the rise in the temperature of the surface of the air flow channel body 8.

[0059] (2) In addition, in the present embodiment, the heater 9 is provided at a position facing both the first flow channel body 81 and the second flow channel body 82. In other words, in the heating section 6 composed of the heater 9 and the air flow channel body 8, the heater 9 and the second flow channel body 82 are arranged overlappingly when viewed from the first direction D1. Thus, it is possible to suppress the increase in the overall thickness of the heating section 6.

[0060] (3) In addition, in the present embodiment, the fan 12 is arranged inside the second flow channel body 82 and in the area that becomes the inside of the first flow channel body 81. In other words, the fan 12 is arranged so as to straddle the two areas of the first flow channel body 81 and the second flow channel body 82. Thus, even if the fan 12 is a component of a size that cannot be arranged inside the first flow channel body 81, since a part of the fan 12 is arranged in the area of the second flow channel body 82, it is also possible to suppress the enlargement of the entire heating section 9.

[0061] (4) Further, in the present embodiment, the intake port 10 is provided at a position of the end portion of the first flow path body 81 on the side opposite to the second flow path body 82. Thus, fresh air from the outside is sucked in from the intake port 10 at the said position, and flows across the entire length of the first flow path body 81 and reaches the inside of the second flow path body 82. Then, it flows through the inside of the second flow path body 82 and is blown out from the blowout port 11. Therefore, by bringing the first flow path body 81 and the second flow path body 82 into contact with the fresh air from the outside, it is possible to effectively suppress the temperature rise of the entire surface of the air flow path body 8.

[0062] In addition, since the distance between the intake port 10 and the fan 12 can be ensured to be large, it is possible to reduce the suction loss caused by the large curvature of the portion that is the intake part of the outside air.

[0063] (5) Further, in the present embodiment, a wall portion 15 is provided between the fan 12 and the blowout port 11, and the wall portion 15 guides the direction Fa of the air sent out from the fan 12 to the position where the blowout port 11 is arranged as indicated by the arrow A. Thus, even if the direction Fa of the air sent out by the fan 12 and the direction Fb of the air blown out from the blowout port 11 are different, since the air sent out from the fan 12 first collides with the wall portion 15, the air can be guided to the blowout port 11 while diffusing in the width direction (X-axis direction) intersecting with the conveying direction by passing through the wall portion 15.

[0064] (6) Further, in the present embodiment, since a plurality of blowout ports 11 are arranged in the width direction (X-axis direction) of the conveying path 3, it is possible to blow out air uniformly in the width direction (X-axis direction).

[0065] (7) Further, in the present embodiment, since the first direction D1 is the vertical direction, it is possible to promote miniaturization of the recording device 1 in the front-rear direction.

[0066] Other embodiments

[0067] Although the recording device 1 according to the present invention is based on the structure having the above-described embodiment, it is obvious that partial structural changes and omissions can be implemented without departing from the gist of the invention of the present application.
