Description

Technical Field

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

[0002] Heretofore, various printing devices have been used. Among them, there is a printing device including a printing unit that performs printing on a medium and a winding unit that supports a paper tube around which the medium is wound in a manner of clamping in the axial direction and winds the medium into a roll shape. For example, Patent Document 1 discloses a printing device including a printing unit that performs printing on a medium and a winding unit that supports a paper tube around which the medium is wound in a manner of clamping in the axial direction by a holding unit and winds the medium into a roll shape.

[0003] In an existing printing device having a printing unit and a winding unit with a structure such as that of the printing device in Patent Document 1, in order to clamp a paper tube around which a medium is wound or the like from both sides in the width direction corresponding to the axial direction of the paper tube, a rail-shaped support member that can move in the width direction of the winding unit is generally provided at the lower part of the winding unit. However, when configured in this way, there is a tendency for the printing device to become larger in the height direction. For this reason, when attempting to change the configuration of the winding unit relative to the support member from a substantially vertical direction to a substantially horizontal direction to suppress the height of the printing device, there is a tendency for the space for performing an operation of removing the medium wound into a roll shape, that is, the roll body, to become narrow, making the operation difficult to perform.

[0015] First, the present invention will be briefly described.

[0016] A printing apparatus according to a first aspect of the present invention for solving the above problems is characterized by comprising: a printing unit that performs printing on a medium; a winding unit that supports a paper tube around which the medium is wound in a clamping manner in an axial direction of the paper tube and winds the medium; a support member that extends in an extending direction parallel to the axial direction when the paper tube is supported by the winding unit and supports the winding unit from a support direction that intersects a vertical direction and the extending direction; and a medium receiving unit that is held by the support member and receives a cylindrical body of the medium wound in a roll shape and removed from the winding unit, wherein the medium receiving unit has a medium placement portion that protrudes in the support direction, and the medium placement portion can place the cylindrical body.

[0017] According to this mode, there is a support member that supports the winding unit in a support direction intersecting the vertical direction. Therefore, the arrangement of the winding unit relative to the support member can be changed from a substantially vertical direction to a substantially horizontal direction, and the height of the printing device can be suppressed. In addition, the medium receiving portion that receives the roll body is held by the support member, and the medium receiving portion has a medium placement portion that protrudes in the support direction, and the medium placement portion can place the roll body. Therefore, when the roll body is removed from the winding unit, the roll body can be temporarily placed on the medium placement portion of the medium receiving portion. In addition, since the medium receiving portion is held by the support member, the moving distance of the roll body at this time is short, and it is also easy to place the roll body on the medium placement portion. Therefore, it is possible to suppress the enlargement of the printing device and at the same time reduce the burden of the roll body disassembly operation.

[0018] The printing device according to the second mode of the present invention is a mode subordinate to the first mode, and is characterized in that the medium receiving portion has an engaging portion that engages with the support member and an intermediate portion disposed between the engaging portion and the medium placement portion.

By adopting such a structure, the medium placement portion can be appropriately arranged when the roll body is placed on the medium placement portion, and when the roll body is not placed on the medium placement portion, the medium placement portion can be arranged at a position that does not hinder the operator, etc.

[0022] The printing device according to the fourth mode of the present invention is a mode subordinate to the second mode, and is characterized in that the intermediate portion is composed of a flexible member.

[0023] According to this mode, the intermediate portion is composed of a flexible member. By adopting such a structure, when a strong force is applied to the medium receiving portion, the force can be diverted, and damage to the medium receiving portion can be suppressed.

[0024] The printing apparatus according to the fifth aspect of the present invention is a mode subordinate to any one of the first to fourth aspects, and is characterized in that the medium receiving portion is movable relative to the support member in the extending direction.

[0025] According to this aspect, the medium receiving portion is movable relative to the support member in the extending direction. By adopting such a structure, it is possible to appropriately arrange the medium receiving portion relative to the support member corresponding to media of various lengths in the axial direction, and the burden of the disassembly operation of the winding cylinder can be reduced.

[0026] The printing apparatus according to the sixth aspect of the present invention is a mode subordinate to any one of the first to fourth aspects, and is characterized in that the medium receiving portion is engaged with the support member from the vertical direction.

[0027] According to this aspect, the medium receiving portion is engaged with the support member from the vertical direction. By adopting such a structure, the medium receiving portion can be simply and accurately mounted on the support member.

[0028] The printing apparatus according to the seventh aspect of the present invention is a mode subordinate to any one of the first to fourth aspects, and is characterized in that the medium placing portion is capable of changing the length in the supporting direction.

By adopting such a structure, it is possible to appropriately change the length in the supporting direction of the medium placing portion corresponding to winding cylinders of various diameters, and it is possible to correspond to winding cylinders of various diameters.

[0030] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. First, with reference to Figure 1 , an outline of the printing apparatus 1 according to an embodiment of the present invention will be described. In addition, in Figure 1 , in order to facilitate understanding of the structure, some structural components are simplified and omitted. Here, in Figure 1 , the X-axis direction in the drawing is the horizontal direction and is the extending direction of the support portion of the supply unit 2 that holds the winding cylinder R1 formed by winding the medium M into a cylindrical shape, 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, and the Z-axis direction is the vertical direction. In addition, hereinafter, the direction in which the arrow mark faces is set as the + direction, and the direction opposite to the direction in which the arrow mark faces is set as the - direction. For example, in Figure 1 , the vertically upward direction is the +Z direction, the vertically downward direction 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.

[0031] As in Figure 1As shown, the printing apparatus 1 of the present embodiment includes a main body 9, and leg frames 7 are installed near both ends of the main body 9 in the X-axis direction. In addition, the printing apparatus 1 of the present embodiment includes a supply unit 2 that holds a roll body R1 on the rear side, i.e., the -Y direction side, of the main body 9. The supply unit 2 supports the paper tube of the roll body R1 around which the medium M is wound in a manner of clamping in the X-axis direction, and supplies the medium M to the head 5 that serves as a printing unit.

[0032] Moreover, in the printing apparatus 1 of the present embodiment, when the medium M is conveyed in the conveyance direction A, the supply unit 2 rotates the roll body R1 in the rotation direction C. Additionally, in Figure 1 , a roll body R1 wound in such a manner that the image forming surface M1 for forming an image faces outward is used, and in the case of using a roll body R1 wound in such a manner that the image forming surface M1 faces inward, the supply unit 2 can rotate the roll body R1 in a direction opposite to the rotation direction C to feed out the medium M.

[0033] In addition, the printing apparatus 1 of the present embodiment includes a conveyance path for the medium M constituted by a medium support unit 3 that supports the medium M using a support surface 30 and the like. As the medium support unit 3, the printing apparatus 1 of the present embodiment includes an upstream medium support unit 3A, a medium support unit 3B, and a downstream medium support unit 3C from the upstream side to the downstream side in the conveyance direction A. In addition, as a conveyance unit for conveying the medium M in the conveyance direction A in this conveyance path, the printing apparatus 1 includes a pair of rollers 8 constituted by a drive roller and a driven roller. However, the structure of the conveyance unit is not particularly limited.

[0034] In addition, the printing apparatus 1 of the present embodiment includes a head 5 that serves as a printing unit and a carriage 4 that mounts the head 5 and can reciprocate in the width direction B at a position opposed to the medium support unit 3B. The head 5 is provided with a plurality of nozzles and ejects ink as a liquid from the nozzles to form an image. In addition, in the printing apparatus 1 of the present embodiment, the conveyance direction A at a position opposed to the head 5 on the medium support unit 3B is the +Y direction, the width direction B, which is the moving direction of the head 5, is a direction along the X-axis direction, and the ejection direction of the ink is the -Z direction.

[0035] According to the above structure, the head 5 can eject ink from nozzles (not shown) to the conveyed medium M while reciprocating in the width direction B, which is a direction intersecting the conveyance direction A, thereby forming 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 the head 5 moves in the width direction B in a state where the medium M is stopped.

[0036] In addition, a heater 20 is provided at the downstream-side medium support portion 3C in the medium support portion 3 as a heating unit for heating the supported surface M2 of the medium M on the side opposite to the image formation surface M1. The heater 20 in this embodiment is composed of a heating wire or the like, but is not limited to such a structure. In addition, it may be configured such that a medium heating unit for heating the supported surface M2 of the medium M on the side opposite to the image formation surface M1 is provided not only at the downstream-side medium support portion 3C but also at the upstream-side medium support portion 3A and the medium support portion 3B.

[0037] In addition, a blowing unit 10 is provided at a portion of the conveyance path that faces the downstream-side medium support portion 3C. The 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 blowing unit 10 in this embodiment has a structure including a fan 11 that generates the air flow F and is capable of blowing the gas as the air flow F toward the image formation surface M1 of the medium M, but is not limited to such a structure.

[0038] In addition, a winding unit 6 is provided downstream of the downstream-side medium support portion 3C in the conveyance direction A. The winding unit 6 winds the medium M conveyed in the conveyance direction A into a roll shape to form a roll body R2. In addition, in the printing apparatus 1 of this embodiment, the supply unit 2 and the winding unit 6 have the same structure. The medium M conveyed from the supply unit 2 to the winding unit 6 is conveyed in a state where a predetermined tension is applied by the winding unit 6 or the like. The winding unit 6 supports the core of the roll body R2, i.e., the paper tube, in a manner of clamping it in the X-axis direction, and winds the medium M into a roll shape by rotating the paper tube. In Figure 1 the winding unit 6 winds the roll body R2 in the rotation direction C so that the image formation surface M1 faces the outside, but the medium M may also be wound in such a manner that the image formation surface M1 faces the inside. In such a case, the winding unit 6 rotates the roll body R2 in a direction opposite to the rotation direction C.

[0039] In addition, a guide rod 200 is provided between the downstream-side medium support portion 3C and the winding unit 6 in the conveyance direction A. The guide rod 200 has a contact surface 201 that is arc-shaped when viewed from the width direction B. Moreover, the guide rod 200 guides the conveyance of the medium M by contacting the supported surface M2 of the medium M to be wound by the winding unit 6 through the contact surface 201. However, the structure of the guide rod 200 is not particularly limited, and furthermore, it may also be a structure without the guide rod 200.

[0040] As described above, the printing apparatus 1 of the present embodiment includes a head 5 and a winding unit 6. The head 5 performs printing on a medium M, and the winding unit 6 supports a paper tube in a clamping manner in the X-axis direction corresponding to the axial direction of the paper tube around which the medium M is wound, and winds the medium M. Hereinafter, a method for detaching a roll body R2 of the medium M wound by the winding unit 6 of the printing apparatus 1 of the present embodiment and its structure will be described with reference to Figures 2 to 7 and, if necessary, with that of the printing apparatus 50 representing a reference example Figure 8 and Figure 9 for comparison.

[0041] As Figure 2 , Figure 3 and Figure 6 show, the printing apparatus 1 of the present embodiment includes a stay 61 that extends in an extending direction parallel to the X-axis direction, which is the axial direction when the paper tube of the roll body R2 is supported by the winding unit 6. Moreover, the stay 61 supports the winding unit 6 in a supporting direction (Y-axis direction) that intersects the vertical direction (Z-axis direction) and the extending direction (X-axis direction). Therefore, in the printing apparatus 1 of the present embodiment, the arrangement of the winding unit 6 relative to the stay 61 can be set to be substantially horizontal rather than substantially vertical, and the height of the printing apparatus 1 can be suppressed.

[0042] In addition, as Figure 2 , Figure 3 and Figure 6 show, the printing apparatus 1 of the present embodiment holds a medium receiving portion 100 on the stay 61, and the medium receiving portion 100 receives the roll body R2 of the medium wound in a roll shape and detached from the winding unit 6. Here, the medium receiving portion 100 has a medium placing portion 101 that protrudes in the supporting direction (Y-axis direction), and as Figure 6 shows, the medium placing portion 101 can place the roll body R2. Therefore, when the printing apparatus 1 of the present embodiment detaches the roll body R2 from the winding unit 6, the roll body R2 can be temporarily placed on the medium placing portion 101 of the medium receiving portion 100. In addition, as Figure 6 shows, since the medium receiving portion 100 is held by the stay 61, the moving distance L1 of the roll body R2 at this time is short, and it is also easy to place the roll body R2 on the medium placing portion 101. Therefore, the printing apparatus 1 of the present embodiment has a structure that can reduce the burden of the detaching operation of the roll body R2 while suppressing enlargement. In addition, of course, by having the medium receiving portion 100 with such a structure, it is possible to suppress the case where the roll body R2 comes into direct contact with the installation surface G, and it is also possible to suppress the case where the roll body R2 is contaminated by contacting the installation surface G.

[0043] The structure of the medium receiving unit 100 provided with the medium placing unit 101 on which the cylindrical body R2 can be placed is particularly useful, especially in a printing apparatus that suppresses the height in the vertical direction. Hereinafter, regarding this point, a comparison will be made Figure 2 and Figure 3 and Figure 8 and Figure 9 will be described. As described above, in the printing apparatus 1 of the present embodiment, in order to suppress the height in the vertical direction, the support member 61 supports the winding unit 6 from the horizontal direction. Therefore, as Figure 2 and Figure 3 show, the height H1 from the installation surface G of the printing apparatus 1 to the top end of the medium support unit 3B corresponding to the height of the take-out portion of the cylindrical body R2 becomes lower. On the other hand, in the printing apparatus 50 of the reference example as Figure 8 and Figure 9 show, the support member 61 supports the winding unit 6 from the vertical direction. Therefore, the height H2 from the installation surface G of the printing apparatus 50 to the top end of the medium support unit 3B corresponding to the height of the take-out portion of the cylindrical body R2 becomes higher.

[0044] As Figure 8 and Figure 9 show in the printing apparatus 50 of the reference example, if the height of the take-out portion of the cylindrical body R2 is high, the operator can take out the cylindrical body R2 without feeling a large working load. On the other hand, as Figure 2 and Figure 3 show in the printing apparatus 1 of the present embodiment, if the height of the take-out portion of the cylindrical body R2 is low, the operator has to maintain a low posture for a long time when taking out the cylindrical body R2 and is likely to feel a large working load. Therefore, in the printing apparatus 1 of the present embodiment, by providing the medium receiving unit 100 having the structure as described above, the working load is reduced.

[0045] Next, hereinafter, a preferred embodiment of the medium receiving unit 100 that can be installed on the printing apparatus 1 of the present embodiment will be described. As Figure 4 and Figure 5 show, the medium receiving unit 100 of the present embodiment has the following structure, that is, in addition to having the medium placing unit 101, it also has an engaging portion 103 that engages with the support member 61 and an intermediate portion 102 disposed between the engaging portion 103 and the medium placing unit 101. By adopting such a structure, the medium receiving unit 100 can be made into a structure in which the cylindrical body R2 can be easily placed on the medium placing unit 101.

[0046] In addition, as Figure 2 , Figure 3 and Figure 6As shown in the figure, when the winding cylinder R2 is removed from the winding unit 6 in the printing apparatus 1 of the present embodiment, the medium placement unit 101 is in a state of being disposed on the installation surface G of the printing apparatus 1. Therefore, the structure is such that the medium receiving unit 100 will not be damaged when the heavy winding cylinder R2 is placed on the medium placement unit 101.

[0047] Specifically, in the printing apparatus 1 of the present embodiment, the engaging portion 103 and the intermediate portion 102 are rotatably connected at the joint portion 102a by an axis parallel to the extending direction (X-axis direction) of the support member 61, and the intermediate portion 102 and the medium placement unit 101 are rotatably connected at the joint portion 102b by an axis parallel to the extending direction of the support member 61, so that the medium placement unit 101 is in a state of being disposed on the installation surface G of the printing apparatus 1. By adopting such a structure, when the winding cylinder R2 is placed on the medium placement unit 101, it is possible to appropriately configure the state in which the medium placement unit 101 is disposed on the installation surface G. Further, when there is no plan to place the winding cylinder R2 on the medium placement unit 101, the medium placement unit 101 can be folded upward at the joint portion 102a and the joint portion 102b, so that the medium placement unit 101 is disposed at a position where it does not obstruct the operator, etc.

[0048] As described above, the medium receiving unit 100 of the present embodiment can change the configuration of the intermediate portion 102 relative to the engaging portion 103 at the joint portion 102a and the configuration of the medium placement unit 101 relative to the intermediate portion 102 at the joint portion 102b. Specifically, as Figure 5 shown, it is possible to change the configuration of the center positions of the intermediate portion 102 and the medium placement unit 101 when viewed from the side relative to the reference position P0 shown by the solid line to the position P2 shown by the dotted line from the position P1 shown by the one-dot chain line.

[0049] However, the medium receiving unit 100 is not limited to such a structure. For example, as Figure 7 shown, it may be configured such that the intermediate portion 102 is directly fixed to the engaging portion 103 and the medium placement unit 101 without passing through a joint portion or the like, and the intermediate portion 102 is constituted by a flexible member. By adopting such a structure, it is also possible to bring the medium placement unit 101 into a state of being disposed on the installation surface G of the printing apparatus 1, and when a strong force is applied to the medium receiving unit 100, the force can be diverted, and damage to the medium receiving unit 100 can be suppressed. In addition, Figure 7 the intermediate portion 102 of the medium receiving unit 100 of is constituted by an elastic member made of rubber, but the intermediate portion 102 may be made of a cloth product, or the intermediate portion 102 may be constituted by an elastic member such as a spiral spring.

[0050] Here, the medium receiving unit 100 of the present embodiment is asFigure 3 There are two medium receiving parts, 100A and 100B, as shown, and they are both configured to be movable relative to the support member 61 in the extending direction thereof, i.e., the X-axis direction. By adopting such a structure for the printing apparatus 1 of the present embodiment, the medium receiving part 100 can be appropriately arranged relative to the support member 61 corresponding to media M of various widths (lengths in the axial direction), thereby reducing the burden of the disassembly operation of the winding cylinder R2.

[0051] There is no limitation on the structure that enables the medium receiving part 100 to move relative to the support member 61 in its extending direction. The medium receiving part 100 of the present embodiment has the following structure, that is, as Figure 4 and Figure 5 shown, etc., the engaging part 103 is engaged with the support member 61 in a state of being hooked at the hooking part 103a from the vertical direction. By adopting such a structure for the printing apparatus 1 of the present embodiment, the medium receiving part 100 can be simply and accurately mounted on the support member 61.

[0052] In addition, by comparing Figure 2 and Figure 5 and Figure 4 and Figure 6 it can be seen that in the printing apparatus 1 of the present embodiment, the medium placing part 101 has a pulling part 101a and is configured to be able to change the length in the supporting direction (Y-axis direction). By adopting such a structure for the printing apparatus 1 of the present embodiment, the length in the supporting direction of the medium placing part 101 can be appropriately changed corresponding to winding cylinders R2 of various diameters, so as to correspond to winding cylinders R2 of various diameters.

[0053] Here, an example of the procedure for removing the winding cylinder R2 from the winding part 6 will be described. First, as Figure 6 shown, etc., the medium placing part 101 is set on the installation surface G of the printing apparatus 1. Then, the length in the supporting direction of the medium placing part 101 is changed according to the diameter of the winding cylinder R2. When the diameter of the winding cylinder R2 is large, the length in the supporting direction of the medium placing part 101 is lengthened. When the diameter of the winding cylinder R2 is small, the length in the supporting direction of the medium placing part 101 is slightly lengthened or not lengthened at all according to the situation.

[0054] Then, as Figure 6As shown, the state where the winding cylinder R2 is mounted on the winding unit 6, i.e., the state of the winding cylinder R2a, becomes the state where the winding cylinder R2 is placed on the medium placement unit 101, i.e., the state of the winding cylinder R2b. At this time, the winding cylinder R2 moves downward in the vertical direction (-Z direction) by a distance of L1. Next, from the state of the winding cylinder R2b, the winding cylinder R2 rolls and moves in the +Y direction by a distance of L2 to become the state of the winding cylinder R2c. That is, the winding cylinder R2 is arranged on the top side of the medium placement unit 101. In the state of the winding cylinder R2c, since the winding cylinder R2 is arranged on the +Y direction side relative to the downstream medium support portion 3C, the winding cylinder R2 can be easily removed from the medium placement unit 101.

[0055] The present invention is not limited to the above-described embodiments and can be implemented by various structures without departing from its gist. In addition, in order to solve part or all of the above problems, or 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. In addition, as long as the technical feature is not described as an essential technical feature in this specification, it can be appropriately deleted.

[0056] For example, in the above embodiment, the medium receiving unit 100 is provided at a position where the winding cylinder R2 mounted on the winding unit 6 can be removed. However, the medium receiving unit 100 may also be provided at a position where the winding cylinder R1 mounted on a supply unit 2 such as a support provided on the supply unit 2 side can be removed. The downstream medium support portion 3C on the winding unit 6 side is likely to be lengthened to dry the ink ejected onto the medium M, and the height H1 from the installation surface G of the printing apparatus 1 to the top end of the medium support portion 3B is likely to be lowered. Therefore, it is preferable that the medium receiving unit 100 is installed on the winding unit 6 side. However, since the medium receiving unit 100 having the above structure is small and high-performance, it can of course also be installed on the supply unit 2 side.
