JP 2017-179655 A

  However, in the conventional inkjet printer, when the position of the textile in the direction orthogonal to the transport direction of the textile is shifted in the feeding section, the position of the image printed on the textile in the printing section is the direction orthogonal to the transport direction of the textile. , There is a problem that the quality of the printed matter is degraded because of deviation from the textile.

  Therefore, an object of the present invention is to provide a printing apparatus that can improve the quality of a printed matter.

  The printing apparatus of the present invention includes a printing unit that performs printing on a medium, a tension applying unit that applies a tension to the medium conveyed to the printing unit, and a position of the medium in a direction orthogonal to the medium conveyance direction. And a media position correcting unit for executing the correction of the above, wherein the medium position correcting unit is arranged on the upstream side of the tension applying unit on the transport path of the medium.

  With this configuration, in the printing apparatus of the present invention, the position of the image to be printed on the medium is orthogonal to the transport direction of the media because the media position correction unit executes the correction of the position of the media in the direction orthogonal to the transport direction of the media. It is possible to suppress deviation from the medium in the direction, and it is possible to improve the quality of printed matter. The media position correction unit is configured to correct the position of the medium in a direction orthogonal to the direction in which the medium is conveyed. Need more. In the printing apparatus according to the aspect of the invention, since the media position correcting unit is disposed on the upstream side of the tension applying unit in the medium transport path, the media position correcting unit is disposed on the downstream side of the tension applying unit in the medium transport path. The media position correction unit can be located away from the printing unit in the media transport path as compared to the configuration in which It is possible to easily secure a sufficient distance not to contact the member.

  In the printing apparatus according to the aspect of the invention, the tension applying unit applies tension to the medium by pulling the medium by pressing the medium in a direction orthogonal to a surface of the medium, and the medium position correcting unit includes: The correction may be performed using the movement of the medium, which is generated by the tension applying unit pulling the medium.

  Generally, the printing device preferably has a higher printing speed. Therefore, it is preferable that the moving speed of the medium caused by the conveyance of the medium by the conveying unit of the printing unit be high. On the other hand, the movement of the medium caused by the tension applying section pulling the medium is performed at a different time from the movement of the medium caused by the conveyance of the medium by the conveyance section of the printing section. The moving speed may be lower than the moving speed of the medium, which is generated by the conveyance of the medium by the method. In the printing apparatus according to the aspect of the invention, the media position correction unit performs the correction of the position of the medium in the direction orthogonal to the transport direction of the medium by using the movement of the medium generated by the tension applying unit pulling the medium. By using the movement of the media, which is generated by the transport of the media by the transport unit of the printing unit, in comparison with the configuration in which the media position correction unit performs the correction of the position of the media in a direction orthogonal to the transport direction of the media, The moving speed of the media when passing near the media position correcting unit can be reduced, and as a result, the media position can be corrected at a moving speed more suitable for correcting the position of the media in a direction orthogonal to the transport direction of the media. The media can pass near the section. Therefore, the printing apparatus of the present invention can effectively execute the correction of the position of the medium in the direction orthogonal to the direction in which the medium is transported by the medium position correction unit.

  In the printing apparatus according to the aspect of the invention, the printing unit includes a transport unit that transports the medium, and the transport unit includes a transport member that transports the medium by being moved while the medium is adhered to a surface. You may have.

  When the length of the medium transport path between the media position correcting unit and the transport member is short, when the position of the medium in the direction orthogonal to the medium transport direction is corrected by the medium position correcting unit, the medium is transported. When a force is applied to a portion adhered to the member in a direction perpendicular to the direction in which the medium is transported, there is a possibility that peeling of the medium from the transport member may occur. However, in the printing apparatus of the present invention, since the media position correcting unit is disposed on the upstream side of the tension applying unit in the media transport path, the media position correcting unit is disposed on the downstream side of the tension applying unit in the media transport path. In comparison with the configuration described above, it is possible to secure a longer length of the media transport path between the media position correction unit and the transport member. Therefore, when the position of the medium in the direction orthogonal to the medium conveyance direction is corrected by the medium position correction unit, the printing device of the present invention moves the medium position correction unit downstream of the tension applying unit in the medium conveyance path. Compared with the configuration in which the media are conveyed, it is difficult for a force to be applied to a portion of the media adhered to the transport member in a direction orthogonal to the transport direction of the media. As a result, a portion of the media adhered to the transport member When a force is applied in a direction perpendicular to the medium transport direction, the possibility of peeling of the medium from the transport member can be reduced.

  The printing apparatus of the present invention can improve the quality of printed matter.

  FIG. 9A is a schematic front view of the centering unit 51 in a state where the medium 90 is shifted to the left. FIG. 9B is a schematic front view of the centering unit 51 in a state where the centering of the medium 90 has been executed.

  The movement of the medium 90 caused by the tension bar 42 (see FIG. 6) pulling the medium 90 causes the end 90a of the medium 90 in the left-right direction to move between the pair of rollers 51b of the centering unit 51. In this case, when the medium 90 is shifted to the left side as shown in FIG. 9A, the control unit 79 (see FIG. 11) described later notifies the end sensor 44 that the medium 90 is shifted to the left side. When it is detected, the space between the pair of rollers 51b of the right centering unit 51 is closed by the motor 51c (see FIG. 6), and as shown in FIG. 9B, the pair of rollers 51b of the right centering unit 51 closes. The media 90 to the right. The case where the medium 90 is shifted to the left has been described above. However, similarly, when the medium 90 is shifted to the right side, the movement of the medium 90 caused by the tension bar 42 pulling the medium 90 causes the end 90 a of the medium 90 in the left and right direction to move toward the pair of the centering units 51. When moving between the rollers 51b of the centering unit 51 on the left side, when the end sensor 44 detects that the medium 90 is shifted to the right side, the controller 79 moves between the pair of rollers 51b of the centering unit 51 on the left side. Is closed by the motor 51c, whereby the medium 90 is pulled to the left by the pair of rollers 51b of the centering unit 51 on the left. As described above, the centering unit 51 executes the centering using the movement of the medium 90, which is generated by the tension bar 42 pulling the medium 90.

  FIG. 10A is a side sectional view of the media movement restriction device 52 in a state where the movement of the medium 90 is not restricted. FIG. 10B is a side cross-sectional view of the medium movement restriction device 52 in a state where movement of the medium 90 is restricted.

  As shown in FIG. 10, the media movement restricting device 52 includes a roller 52 a on which the medium 90 is hung, a bar 52 b that sandwiches the medium 90 together with the roller 52 a to restrict the movement of the medium 90, and a bar support member that supports the bar 52 b. 52c, a rotation shaft 52d that rotatably supports the bar support member 52c, and an air cylinder 52e that rotates the bar support member 52c about the rotation shaft 52d.

  The media movement restricting device 52 has a state in which the stroke of the air cylinder 52e is changed so that the movement of the medium 90 is not restricted as shown in FIG. The state changes to a state in which the movement of the 90 is restricted.

  As shown in FIGS. 6 and 7, the roller 52a forms a bent portion of the transport path of the medium 90. The roller 52a is adjacent to the centering unit 51 on the upstream side in the transport path of the medium 90. The centering unit 51 and the roller 52a are arranged side by side in the vertical direction.

  In order to execute centering, the centering unit 51 is located on the upstream side of the transport path of the medium 90, and the distance that the medium 90 does not contact with other members is, for example, a specific distance such as the width of the medium 90 in the left-right direction. It must be longer than the length. Therefore, the distance between the centering unit 51 and the roller 52a is equal to or longer than a specific length.

  FIG. 11 is a block diagram of the inkjet printer 10.

  As shown in FIG. 11, the inkjet printer 10 includes a belt moving device 71 that moves the conveyor belt 21a (see FIG. 3) by rotating a roller 21b (see FIG. 3), and a rail 24 (see FIG. 3). ), The carriage moving device 72 for moving the carriage 22 (see FIG. 3) in the left-right direction, the plurality of inkjet heads 23, the roll support device 41, and the tension bar 42 (see FIG. 3) in the vertical direction. A tension bar sensor 73 for detecting the position, a left end sensor 44, a right end sensor 44, a motor 51c of the left centering unit 51 (see FIG. 3), and a motor 51c of the right centering unit 51. And a cylinder driving device for changing the stroke of the air cylinder 52e (see FIG. 10). 74, an operation unit 75 which is an input device such as a button to which various operations are input, a display unit 76 which is a display device such as an LCD (Liquid Crystal Display) for displaying various information, and a network. Alternatively, a communication unit 77, which is a communication device that directly communicates with an external device by wire or wirelessly without using a network, and a non-volatile memory such as a semiconductor memory that stores various information and an HDD (Hard Disk Drive). A storage unit 78, which is a storage device, and a control unit 79 that controls the entire inkjet printer 10 are provided.

  The control unit 79 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory) storing programs and various data, and a RAM (Random Access Memory) used as a work area of the CPU. I have. The CPU executes a program stored in the ROM or the storage unit 78.

  Next, the operation of the inkjet printer 10 will be described.

  Upon receiving the print data via the communication unit 77, the control unit 79 executes printing on the medium 90 based on the print data received via the communication unit 77. That is, the control unit 79 executes printing on the medium 90 in the left-right direction by moving the carriage 22 in the left-right direction by the carriage moving device 72 and discharging ink toward the medium 90 by the inkjet head 23. When printing on the medium 90 in the left-right direction is performed, the control unit 79 moves the medium 90 adhered to the conveyance belt 21a in the front-rear direction by moving the conveyance belt 21a by the belt moving device 71 as necessary. Transport. Then, after changing the position of printing on the medium 90 in the front-rear direction, the control unit 79 executes printing on the medium 90 in the left-right direction again as necessary.

  The control unit 79 restricts the movement of the medium 90 fed from the roll 91 by the roll support device 41 while the transport belt 21 a is moved by the belt moving device 71, and is fed out via the centering device 50. As for the medium 90, the movement of the medium 90 is restricted by the medium movement restricting device 52 by the cylinder driving device 74. Therefore, when part of the medium 90 is moved by the conveyor belt 21a, another part of the medium 90 is newly attached to the conveyor belt 21a while being tensioned by the tension bar 42.

  When the position of the tension bar 42 detected by the tension bar sensor 73 is higher than a specific position (hereinafter, referred to as a “first position”), the controller 79 causes the belt moving device 71 to move the transport belt 21a. When the medium 90 is unwound from the roll 91, the restriction on the movement of the medium 90 by the roll support device 41 is released for the medium 90 unwound from the roll 91. The restriction on the movement of the medium 90 by 52 is released. Therefore, when the medium 90 is fed out of the roll 91 without passing through the centering device 50, the medium 90 is fed out of the roll 91 toward the tension bar 42 by an amount pulled by the tension bar 42, and is fed out through the centering device 50. The portion of the transport path of the medium 90 on the upstream side of the media movement restricting device 52 is fed to the tension bar 42 side by the amount pulled by the tension bar 42. Then, when the position of the tension bar 42 detected by the tension bar sensor 73 is lower than the second position lower than the first position, the control unit 79 controls the roll supporting device 41 for the medium 90 fed from the roll 91. The movement of the medium 90 is restricted by the cylinder driving device 74 with respect to the medium 90 fed out through the centering device 50 while the movement of the medium 90 is restricted. Therefore, when the medium 90 is unwound from the roll 91 without passing through the centering device 50, the portion of the medium 90 on the downstream side of the roll supporting device 41 in the transport path of the medium 90 is transported by the transport belt 21a. When it is fed out to the side of the media 21a and is fed out via the centering device 50, a portion of the media 90 on the transport path downstream of the media movement restricting device 52 is extended to the side of the transport belt 21a by the amount transported by the transport belt 21a. It is.

  When the control unit 79 determines that the medium 90 is shifted to one of the left side and the right side based on the detection result of the end sensor 44, the control unit 79 determines that the medium 90 is shifted to one of the left side and the right side. Until the determination is stopped, the motor 51c of the other of the left and right centering units 51 closes the space between the pair of rollers 51b of the centering unit 51. Therefore, as described above, the position of the medium 90 in the left-right direction is maintained at the center position.

  As described above, since the inkjet printer 10 performs the correction of the position of the medium 90 in the left-right direction orthogonal to the transport direction of the medium 90 by the centering unit 51, the position of the image printed on the medium 90 is changed in the left-right direction. The displacement with respect to the medium 90 can be suppressed, and the quality of printed matter can be improved.

  The centering unit 51 corrects the position of the medium 90 in the left-right direction orthogonal to the direction in which the medium 90 is conveyed. Need more than a certain length. The inkjet printer 10 has a configuration in which the centering unit 51 is disposed on the upstream side of the tension bar 42 in the transport path of the medium 90, and thus the centering unit 51 is disposed on the downstream side of the tension bar 42 in the transport path of the medium 90. As a result, the centering unit 51 can be disposed apart from the printing unit 20 on the transport path of the medium 90. As a result, the media 90 can be positioned immediately upstream of the centering unit 51 on the transport path of the medium 90. It is possible to easily secure a sufficient distance not to contact the member.

  In general, an inkjet printer preferably has a higher printing speed. Therefore, it is preferable that the moving speed of the medium 90 caused by the conveyance of the medium 90 by the conveying unit 21 of the printing unit 20 be high. On the other hand, the movement of the medium 90 caused by the tension bar 42 pulling the medium 90 is performed at a different time from the movement of the medium 90 caused by the conveyance of the medium 90 by the conveyance unit 21 of the printing unit 20. The movement speed may be slower than the movement of the medium 90 caused by the conveyance of the medium 90 by the conveyance unit 21 of the printing unit 20. In the inkjet printer 10, the centering unit 51 executes the correction of the position of the medium 90 in the left-right direction orthogonal to the transport direction of the medium 90 by using the movement of the medium 90 generated by the tension bar 42 pulling the medium 90. Therefore, the centering unit 51 corrects the position of the medium 90 in the left-right direction using the movement of the medium 90 caused by the conveyance of the medium 90 by the conveyance unit 21 of the printing unit 20, The moving speed of the medium 90 when passing through the vicinity of the centering unit 51 can be reduced, and as a result, the medium 90 can be moved near the centering unit 51 at a moving speed more suitable for correcting the position of the medium 90 in the left-right direction. Can be passed through. Accordingly, the centering unit 51 of the inkjet printer 10 can effectively correct the position of the medium 90 in the left-right direction.

  If the length of the transport path of the medium 90 between the centering unit 51 and the transport belt 21a is short, if the position of the medium 90 in the left-right direction orthogonal to the transport direction of the medium 90 is corrected by the centering unit 51, When a force is applied in the left-right direction to a portion of the media 90 that is adhered to the transport belt 21a, there is a possibility that the medium 90 is peeled from the transport belt 21a. However, in the ink jet printer 10, the centering unit 51 is disposed on the upstream side of the tension bar 42 in the transport path of the medium 90. In comparison with the configuration, the length of the transport path of the medium 90 between the centering unit 51 and the transport belt 21a can be secured longer. Therefore, when the position of the medium 90 in the left-right direction is corrected by the centering unit 51, the inkjet printer 10 is compared with a configuration in which the centering unit 51 is disposed downstream of the tension bar 42 in the transport path of the medium 90. Therefore, it is difficult for a force in the left and right direction to be applied to the portion of the medium 90 that is adhered to the transport belt 21a. The possibility that peeling of the medium 90 from the conveyor belt 21a occurs can be reduced.

  The centering unit 51 may have a configuration other than the configuration described in the present embodiment as long as the centering of the medium 90 can be performed.

  The media movement restriction device 52 may have a configuration other than the configuration described in the present embodiment, as long as switching between the restriction on the movement of the medium 90 and the release of the restriction on the movement of the medium 90 is possible.

  When the inkjet printer 10 does not support the feeding of the medium 90 that is not in the form of a roll, that is, when the inkjet printer 10 supports only the feeding of the medium 90 from the roll 91, the movement of the medium 90 is restricted and the movement of the medium 90 is restricted. Can be switched by the roll support device 41, so that the media movement restricting device 52 need not be provided. That is, when the inkjet printer 10 does not support the feeding of the medium 90 that is not in a roll shape, if the inkjet printer 10 includes the roller 52a, the inkjet printer 10 does not include the bar 52b, the bar support member 52c, the rotation shaft 52d, and the air cylinder 52e. May be.
