Description

Technical Field

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

[0002] All kinds of printing devices have been used. Among them, there is a printing device including a printing unit, an impression plate that supports a medium at a position opposed to the printing unit, and a base frame that supports the impression plate. For example, Patent Document 1 discloses a printing device including a print head as a printing unit that performs reciprocating scanning and printing, an impression plate, a base frame, and a pair of leg frames, and the base frame reaches the outside in the reciprocating scanning direction of the print head further than the leg frames.

[0003] In a structure having a so-called protruding portion where the base frame reaches the outside in the moving direction of the printing unit further than the leg frames as in the printing device of Patent Document 1, the protruding portion is liable to deform. Therefore, Patent Document 1 describes a technique of providing, for example, a triangular reinforcing member (so-called beam support member) on the leg frame to reinforce the base frame. However, if a triangular reinforcing member is provided on the leg frame, the space of the installation portion of the triangular reinforcing member cannot be effectively utilized.

[0019] First, a general description of the present invention will be given.

[0020] The printing apparatus according to the first aspect of the present invention for solving the above problems is characterized by including: a printing unit that performs printing on a medium while moving in a moving direction; an impression plate that is disposed at a position opposed to the printing unit within the printing range of the printing unit and supports the medium; a base frame that extends in the moving direction and supports the impression plate; and a pair of leg frames that support the base frame at intervals in the moving direction. The base frame has an overhanging portion that protrudes outward from the leg frames in the moving direction, and the overhanging portion has a reinforcing portion formed by overlapping a plurality of metal plates when viewed from a direction crossing the moving direction.

[0021] According to this aspect, the overhanging portion has a reinforcing portion formed by overlapping a plurality of metal plates when viewed from a direction crossing the moving direction. By adopting such a structure, there is no longer a need to provide new structural components around the leg frames, such as providing reinforcing members on the leg frames. Therefore, the space such as the lower part of the overhanging portion can be effectively utilized, and the base frame having the overhanging portion can be strengthened.

[0022] The printing apparatus according to the second aspect of the present invention is a mode subordinate to the first aspect, and is characterized in that the overhanging portion has different shapes at positions inside and outside the reinforcing portion in the moving direction.

[0023] According to this aspect, the overhanging portion has different shapes at positions inside and outside the reinforcing portion in the moving direction. In this way, by setting the shape of the overhanging portion to be different at positions inside and outside the reinforcing portion, the space can be effectively utilized according to the shape of other structural components and the like.

[0024] The printing apparatus according to the third aspect of the present invention is a mode subordinate to the second aspect, and is characterized in that the overhanging portion has a space shape formed by cutting the lower side upward to form a space at a position outside the reinforcing portion in the moving direction.

[0025] According to this aspect, the overhanging portion has a space shape formed by cutting the lower side upward to form a space at a position outside the reinforcing portion in the moving direction. Therefore, the space void at the lower part of the overhanging portion can be widened, and the space can be particularly effectively utilized according to the shape of other structural components and the like.

[0026] The printing apparatus according to the fourth aspect of the present invention is a mode subordinate to any one of the first to third aspects, and is characterized in that the overhanging portion is constituted by joining a plurality of the metal plates together in the moving direction.

[0027] According to this embodiment, the protruding portion is configured to join a plurality of metal plates together in the moving direction. With such a structure, it is possible to configure without increasing the size of the reinforcing portion. Therefore, the space such as the lower part of the protruding portion can be effectively utilized.

[0028] The printing apparatus according to the fifth aspect of the present invention is an aspect subordinate to any one of the first to third aspects, and is characterized in that a pair of the leg frames are provided at positions sandwiching the platen when viewed from a direction crossing the moving direction.

[0029] According to this embodiment, a pair of leg frames are provided at positions sandwiching the platen when viewed from a direction crossing the moving direction. With such a structure, it is possible to appropriately support the entire printing apparatus by the pair of leg frames.

[0030] The printing apparatus according to the sixth aspect of the present invention is an aspect subordinate to any one of the first to third aspects, and is characterized in that it includes a maintenance unit for maintaining the printing unit, and the maintenance unit is disposed at the protruding portion.

[0031] According to this embodiment, the maintenance unit is disposed at the protruding portion. With such a structure, the space of the printing apparatus can be effectively utilized, and thus the enlargement of the printing apparatus can be suppressed.

[0032] The printing apparatus according to the seventh aspect of the present invention is an aspect subordinate to any one of the first to third aspects, and is characterized in that the protruding portion has a plurality of the reinforcing portions.

[0033] According to this embodiment, the protruding portion has a plurality of reinforcing portions. Therefore, it is possible to effectively reinforce the base frame having the protruding portion.

[0034] The printing apparatus according to the eighth aspect of the present invention is an aspect subordinate to the seventh aspect, and is characterized in that at least two of the reinforcing portions are overlapped by a plurality of the metal plates in different directions.

[0035] According to this embodiment, at least two of the reinforcing portions are overlapped by a plurality of metal plates in different directions. With such a structure, it is possible to reinforce against stresses from a plurality of different directions, and thus it is possible to particularly effectively reinforce the base frame having the protruding portion.

[0036] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. First, mainly with reference to Figure 1 , an outline of a printing apparatus 1 according to an embodiment of the present invention will be described. In addition, in Figure 1In order to facilitate understanding of the structure, some structural components are simplified and omitted from the illustration. Here, the X-axis direction in the figure is the horizontal direction and is the direction in which the support portion of the holding portion 2 that holds the roll body R1 formed by winding the medium M in a roll shape extends. The Y-axis direction is the horizontal direction and is the front-rear direction of the printing apparatus 1 and is a direction orthogonal to the X-axis direction. The Z-axis direction is the vertical direction. Further, hereinafter, the direction toward which the arrow mark points is defined as the + direction, and the direction opposite to the direction toward which the arrow mark points is defined as the - direction. For example, vertically upward is the +Z direction, vertically downward is the -Z direction, the front of the printing apparatus 1 is the +Y direction, and the rear of the printing apparatus 1 is the -Y direction.

[0037] The printing apparatus 1 of the present embodiment includes a main body portion 9 having a base frame 100, the details of which will be described hereinafter. A leg frame 7 is mounted near the end portion in the X-axis direction of the main body portion 9 or inside the end portion. Further, the printing apparatus 1 of the present embodiment includes a holding portion 2 that holds the roll body R1 formed by winding the medium M in a roll shape on the rear side, i.e., the -Y direction side, of the main body portion 9. The holding portion 2 functions as a feeding portion that feeds the medium M from the roll body R1 to the main body portion 9.

[0038] Moreover, in the printing apparatus 1 of the present embodiment, when the medium M is conveyed in the conveying direction A, the holding portion 2 having a rotation axis along the X-axis direction is rotated in the rotation direction C. The holding portion 2 is a member inserted into a paper tube that is the core of the roll body R1. Further, in Figure 1 the roll body R1 wound in such a manner that the image forming surface M1 for forming an image faces outward is used, but in the case of using a roll body R1 wound in such a manner that the image forming surface M1 faces inward, the holding portion 2 can be rotated in the direction opposite to the rotation direction C to feed the medium M from the roll body R1.

[0039] Further, the printing apparatus 1 of the present embodiment has a conveyance path for the medium M constituted by a medium support portion 3 that supports the medium M and the like. The printing apparatus 1 of the present embodiment includes an upstream side medium support portion 3A, an impression plate 3B, and a downstream side medium support portion 3C as the medium support portion 3 from the upstream side to the downstream side in the conveying direction A. Further, the printing apparatus 1 includes a pair of rollers 8 constituted by a driving roller and a driven roller as a conveying portion for conveying the medium M in the conveying direction A on the conveyance path. However, the structure of the conveying portion is not particularly limited.

[0040] In addition, the printing apparatus 1 of the present embodiment includes a head 5 and a carriage 4 as a printing unit at a position facing the impression plate 3B. The head 5 is provided with a plurality of nozzles and ejects ink from the nozzles to form an image. The carriage 4 mounts the head 5 and is capable of reciprocating in the width direction B. Further, in the printing apparatus 1 of the present embodiment, the conveyance direction A at the position on the impression plate 3B facing the head 5 is the +Y direction, the moving direction of the head 5, i.e., the width direction B, is a direction along the X-axis direction, and the ejection direction of the ink is the -Z direction.

[0041] According to the above-described structure, the head 5 can reciprocate in the width direction B, which is a direction crossing the conveyance direction A, and eject ink from nozzles (not shown) onto the conveyed medium M to form an image. The printing apparatus 1 of the present embodiment can form a desired image on the medium M by repeatedly performing an operation of conveying the medium M in the conveyance direction A by a predetermined conveyance amount and an operation of ejecting ink while moving the head 5 in the width direction B in a state where the medium M is stopped. Further, as Figure 2 shown, an ink supply unit 12 capable of mounting a plurality of ink cartridges for storing ink can be disposed on the -X direction side of the main body portion 9, and is configured to supply ink from the ink cartridges mounted on the ink supply unit 12 to the head 5.

[0042] In addition, a heater 20 is provided on the downstream-side medium support portion 3C in the medium support portion 3 as a heating unit for heating the supported surface M2 on the opposite side of the image formation surface M1 of the medium M. The heater 20 of the present embodiment is constituted by a heating wire or the like, but is not limited to such a structure. Further, it may be configured such that a medium heating unit for heating the supported surface M2 on the opposite side of the image formation surface M1 of the medium M is provided not only on the downstream-side medium support portion 3C but also on the upstream-side medium support portion 3A and the impression plate 3B.

[0043] In addition, an air blowing unit 10 is provided at a portion of the conveyance path facing the downstream-side medium support portion 3C. The air blowing unit 10 dries the ink ejected from the head 5 onto the image formation surface M1 of the medium M by blowing out an air flow F. The air blowing unit 10 of the present embodiment has a structure including a fan 11 that generates the air flow F and is capable of blowing air as the air flow F onto the image formation surface M1 of the medium M, but is not limited to such a structure.

[0044] In addition, a holding unit 6 serving as a winding unit is provided downstream of the downstream-side medium support unit 3C in the conveying direction A. The holding unit 6 winds the medium M conveyed in the conveying direction A into a roll shape to form a roll body R2. Further, in the printing apparatus 1 of the present embodiment, the holding unit 2 and the holding unit 6 are configured in the same structure, and the holding unit 6 rotates in the rotational direction C. The holding unit 6 is a member inserted into a paper tube serving as a core of the roll body R2. In Figure 1 the medium M is wound such that the image forming surface M1 faces outward by the rotation of the holding unit 6 in the rotational direction C, but the medium M may be wound such that the image forming surface M1 faces inward. In such a case, the holding unit 6 rotates in the direction opposite to the rotational direction C.

[0045] As described above, the printing apparatus 1 of the present embodiment includes: a head 5 that performs printing on the medium M while moving in the width direction B; an impression plate 3B that is disposed at a position facing the head 5 within the printing range of the head 5 and supports the medium M; a base frame 100 that supports the impression plate 3B; and a pair of leg frames 7 that support the base frame 100. Hereinafter, with reference to Figures 2 to 13 the detailed configuration of the base frame 100, which is the main part of the printing apparatus 1 of the present embodiment, will be described. The base frame 100 is made of a metal plate.

[0046] Here, as Figure 3 and Figure 4 shown, the base frame 100 extends in the width direction B. Further, as Figure 3 and Figure 4 shown, the leg frame 7 includes a leg frame 7A and a leg frame 7B, and is configured to support the base frame 100 while being spaced apart in the width direction B.

[0047] As Figures 3 to 10 shown, the base frame 100 includes a frame 101 that has a surface on the +Y direction side and a surface on the -Z direction side and extends in the width direction B. Further, as Figures 3 to 6 shown, a frame 102 is provided that has a surface on the +Z direction side, can be fixed to the frame 101, and extends in the width direction B. Further, as Figures 7 to 11 shown, a frame 106 is provided that has a surface on the -Y direction side, can be fixed to the frame 101, and extends in the width direction B. Additionally, as Figure 7 shown, a frame 108 is provided in a region surrounded by the frame 101, the frame 102, and the frame 106. The frame 101, the frame 102, the frame 106, and the frame 108 are disposed at a position on the -Z direction side of the impression plate 3B, i.e., at the lower part of the impression plate 3B.

[0048] A part of the frames 101, 102, 106 and 108 extends toward the -X direction side compared to the leg frame 7A. Moreover, as Figures 4 to 10 shown, etc., on the frame 101 and the frame 106, a frame 105 having a +Y direction side surface, a -Z direction side surface and a -Y direction side surface is mounted on their more -X direction side. In addition, as Figures 4 to 6 shown, a frame 104 mounted to the frame 102 via the frame 103 is provided on the +Z direction side of the frame 105. The region where the frame 103 is arranged in the Z-axis direction corresponds to the region where the frames 102, 103 and 104 overlap in the Z-axis direction. Further, a frame 107 (frame 107A and frame 107B) is provided in the region surrounded by the frame 105 and the frame 104. As Figure 9 shown, the frame 107 is mounted on the frame 105 and is mounted on the frame 101 via the frame 109 (frame 109A and frame 109B).

[0049] Thus, the base frame 100 extends outward in the width direction B compared to the leg frame 7A, and the region that extends outward in the width direction B compared to the leg frame 7A is set as the protruding portion 110. The frames 101 and 105 are mounted at the protruding portion 110 as described above, and a part of the frames 101 and 105 overlap each other in the Y-axis direction as Figures 5 to 10 shown. Moreover, the region where a part of the frames 101 and 105 overlap each other in the Y-axis direction constitutes a reinforcing portion 120 (reinforcing portion 120A).

[0050] In addition, the frames 102, 103 and 104 are mounted at the protruding portion 110 as Figures 4 to 6 shown, etc., and the frames 102, 103 and 104 overlap in the Z-axis direction in the region where the frame 103 is arranged. Moreover, the region where the frames 102, 103 and 104 corresponding to the region where the frame 103 is arranged overlap in the Z-axis direction constitutes a reinforcing portion 120 (reinforcing portion 120B).

[0051] In addition, the frames 102, 103 and 104 are mounted at the protruding portion 110 as Figure 9The frame 105 and the frame 107 are installed as shown, and the frame 107 and the frame 101 are installed via the frame 109. Specifically, a part of each of the frame 105 and the frame 107 overlaps with each other in the Z-axis direction, and a part of the frame 107 and the frame 101 overlaps with each other in the Z-axis direction via the frame 109. Moreover, the region where a part of the frame 105 and the frame 107 overlaps with each other in the Z-axis direction and the region where a part of the frame 107 and the frame 101 overlaps with each other in the Z-axis direction via the frame 109 constitute the reinforcing portion 120 (reinforcing portion 120C).

[0052] In addition, at the protruding portion 110, as Figures 9 to 11 shown, the frame 106 and the frame 105 are installed, and a part of the frame 106 and the frame 105 overlaps with each other in the Y-axis direction. Moreover, the region where a part of the frame 106 and the frame 105 overlaps with each other in the Y-axis direction constitutes the reinforcing portion 120 (reinforcing portion 120D).

[0053] As described above, the base frame 100 in the printing apparatus 1 of the present embodiment has the protruding portion 110 that protrudes outward from the foot frame 7A in the moving direction of the head 5, that is, the width direction B. Moreover, the protruding portion 110 has the reinforcing portion 120 formed by overlapping a plurality of metal plates when viewed from the directions intersecting the width direction B corresponding to the X-axis direction, that is, the Y-axis direction and the Z-axis direction. In addition, each frame constituting the base frame 100 may be formed of a single metal plate that is not joined end to end in the width direction B, and other metal plates may be overlapped and arranged for the reinforcing portion 120.

[0054] With the printing apparatus 1 of the present embodiment having such a structure, there is no longer a need to provide new structural components around the foot frame 7 such as providing a reinforcing member on the foot frame 7. Therefore, the printing apparatus 1 of the present embodiment can effectively utilize the space such as the lower part of the protruding portion 110, and can reinforce the base frame 100 having the protruding portion 110. Specifically, the structure is as follows, that is, the base frame 100 is reinforced by the reinforcing portion 120, and as Figure 2 and Figure 13 shown, the ink supply unit 12 can be arranged at the lower part of the protruding portion 110.

[0055] In addition, as described above, in the printing apparatus 1 of the present embodiment, the protruding portion 110 has a plurality of reinforcing portions 120, such as the reinforcing portion 120A, the reinforcing portion 120B, the reinforcing portion 120C, and the reinforcing portion 120D. Therefore, the printing apparatus 1 of the present embodiment can effectively reinforce the base frame 100 having the protruding portion 110 by the plurality of reinforcing portions 120.

[0056] More specifically, as described above, regarding the printing apparatus 1 of the present embodiment, the reinforcing portions 120A and 120D in the reinforcing portion 120 are configured such that a plurality of metal plates overlap in the Y-axis direction, and the reinforcing portions 120B and 120C in the reinforcing portion 120 are configured such that a plurality of metal plates overlap in the Z-axis direction. Thus, it is particularly preferably configured such that at least two of the reinforcing portions 120 are configured such that a plurality of metal plates overlap in different directions. By adopting such a configuration, it is possible to reinforce against stresses and the like from a plurality of different directions, and thus it is possible to particularly effectively reinforce the base frame 100 having the protruding portion 110.

[0057] In addition, from another aspect, in the printing apparatus 1 of the present embodiment, the protruding portion 110 is configured to join a plurality of frames constituting the base frame 100 together in the width direction B, in other words, to join a plurality of metal plates together in the width direction B. By adopting such a configuration, it is possible to configure the apparatus without increasing the size of the reinforcing portion 120. Therefore, as described above, the printing apparatus 1 of the present embodiment can effectively utilize the space such as the lower part of the protruding portion 110.

[0058] In addition, as Figure 2 shown, in the printing apparatus 1 of the present embodiment, a pair of leg frames 7 are provided at positions sandwiching the platen 3B when viewed from a direction intersecting the width direction B. By adopting such a configuration for the printing apparatus 1 of the present embodiment, it is possible to appropriately support the entire printing apparatus 1 by the pair of leg frames 7.

[0059] In addition, as Figure 3 and Figure 13 shown, the printing apparatus 1 of the present embodiment includes a maintenance unit 13 for maintaining the head 5. Moreover, the maintenance unit 13 is provided at the protruding portion 110. By adopting such a configuration for the printing apparatus 1 of the present embodiment, it is possible to effectively utilize the space of the printing apparatus 1, and thus it is possible to suppress an increase in the size of the printing apparatus 1. In addition, the structure of the maintenance unit 13 is not particularly limited, and a structure provided with a suction mechanism, a wiping mechanism, etc. can be preferably used.

[0060] In addition, as Figures 5 to 10 shown, in the printing apparatus 1 of the present embodiment, the protruding portion 110 is formed in different shapes on the inner side (+X direction side) and the outer side (-X direction side) in the width direction B compared to the reinforcing portion 120A. The shape of the protruding portion 110 is not particularly limited. Thus, by forming the shape of the protruding portion 110 in different shapes on the inner side and the outer side compared to the reinforcing portion 120A, it is possible to effectively utilize the space according to the shape of other structural components and the like.

[0061] More specifically, as Figures 5 to 10As shown, in the printing apparatus 1 of the present embodiment, the protruding portion 110 has a space shape 110A that forms a space by cutting the lower side (-Z direction side) upward (+Z direction) at a position outside (-X direction side) the reinforcing portion 120A in the width direction B. Therefore, the printing apparatus 1 of the present embodiment can widen the space void at the lower part of the protruding portion 110, and thus can utilize the space particularly effectively according to the shape of other structural components. Specifically, as Figure 13 shown, it is configured such that the ink supply unit 12 can be effectively arranged in the space void at the lower part of the protruding portion 110. In addition, if it is configured without the space shape 110A, in order to arrange the ink supply unit 12, the overall height of the printing apparatus 1 must be made higher, resulting in the enlargement of the apparatus and ineffective arrangement.

[0062] In the present embodiment, the shape of the protruding portion 110 is formed along the outer shape of the ink supply unit 12. Therefore, when the ink supply unit 12 is arranged at the use position with respect to the printing apparatus 1, as Figure 2 shown, the ink supply unit 12 is accommodated within the installation range of the printing apparatus 1, and the utilization efficiency of the installation space is high. In addition, by making the shape of the protruding portion 110 follow the outer shape of the ink supply unit 12, a sense of unity in design and a sense of visual stability can be created. Further, even when the shape of the protruding portion 110 is not formed to follow the outer shape of the ink supply unit 12, it is effective in terms of the efficiency of the installation space by accommodating the ink supply unit 12 in the space void at the lower part of the protruding portion 110.

[0063] The present invention is not limited to the above-described embodiments and can be implemented by various structures without departing from the gist thereof. In addition, in order to solve part or all of the above problems, or to achieve part or all of the above effects, the technical features in the embodiments corresponding to the technical features in each mode described in the summary of the invention can be appropriately replaced and combined. Further, if the technical feature is not described as an essential technical feature in this specification, it can be appropriately deleted.
