Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an overall configuration diagram of an image recording apparatus according to the present embodiment. An image recording apparatus 1 shown in FIG. 1 is connected to a host apparatus 2 that is a host device of the image recording apparatus 1 such as a personal computer (PC). Image information is recorded on a continuous recording medium (web) 3 in accordance with a command from the host device 2. Here, the image information is information acquired from the host device 2 and includes an image to be recorded on the web 3, perforation processing information, cutting information, and the like. The web 3 is subjected to processing such as image recording, perforation processing, and cutting to a predetermined length in the course of being transported to the transport system.

Hereinafter, the operation of each part of the image recording apparatus 1 according to the present embodiment will be described along the process in which the web 3 is conveyed.
The medium storage unit 4 rotatably supports the web 3 wound in a roll shape. The medium storage portion 4 incorporates a mechanical or magnetic rotary brake, and applies a predetermined tension to the web 3 by braking the pulled-out web 3. As the web 3 is pulled out from the medium storage unit 4, the winding diameter of the web 3 becomes smaller. However, it is necessary to apply a certain tension to the pulled-out web 3 at any winding diameter.

  For this reason, the winding diameter of the web 3 in the medium storage unit 4 is calculated by using the rotational speed at the radius of the web 3 and the transport speed of the web 3 detected in the middle of the transport path, or a sensor (not shown). By directly detecting the winding diameter of the web 3, the winding diameter is obtained. And the brake torque suitable for the winding diameter which the control part 5 calculated | required is given to the rotating shaft of the medium storage part 4, and the tension | tensile_strength given to the web 3 unwound is variably controlled.

  A large-diameter drum (hereinafter simply referred to as a drum) 6 winds and holds the unwound web 3. The drum 6 is rotationally driven by applying a constant tension to prevent the web 3 from slipping, and the driving force generated by the rotational driving of the drum 6 is transmitted to convey the web 3 at a predetermined speed. Further, the conveyance driving force of the web 3 is supplied by a motor (not shown) attached to the rotation shaft of the roller pair 7, and this motor conveys the web 3 at a predetermined speed.

  In addition, a conveyance information generation unit 8 such as a rotary encoder is connected to the rotation shaft of the drum 6. The conveyance information generation unit 8 generates periodic pulses as conveyance information according to the conveyance distance of the web 3. The image recording unit 9 is disposed at a close position along the outer diameter of the drum 6, and records an image according to the image information from the host device 2 on the web 3. Specifically, ink is ejected according to image information from, for example, a line-type inkjet head disposed in the image recording unit 9, and an image is recorded on the web 3. The ink ejection timing is controlled by the control unit 5, and the control of the control unit 5 is performed based on the conveyance information output from the conveyance information generation unit 8.

  The image detection unit 10 is configured by a sensor such as a color image sensor, for example, and reads image information recorded on the web 3 by the image recording unit 9. The image information read by the image detection unit 10 is used by the control unit 5 to determine whether the content recorded on the web 3 is good or bad. For example, it is used to determine the presence or absence of image defects such as non-ejection of ink or landing deviation, and the presence or absence of abnormal image quality such as abnormal ejection of ink or dirt adhering to a recording medium.

  When recording images on both the front and back surfaces of the web 3, two sets of drums 6, image recording units 9, and image detection units 10 having the same configuration are prepared, and each of the front and back surfaces of the web 3 is prepared. The image information is recorded and detected on the surface.

  On the other hand, the web 3 that has passed between the roller pair 7 is conveyed to a perforation processing unit 11 that performs perforation on the web 3. The web 3 conveyed to the perforation processing unit 11 is conveyed between the anvil roller 12 and the perforation blade 13 that rotate at the same peripheral speed as the conveyance speed of the web 3. In addition, although the example shown in this embodiment is a structure provided with the two sewing blades 13a and 13b, in FIG. 2, only one sewing blade 13a (or 13b) is described.

  The image recording apparatus according to the present embodiment processes the perforation on the web 3 by bringing the perforation blades 13a and 13b of the perforation processing unit 11 into contact with the anvil roller 12 and then separates (retracts) the perforation. Is to stop.

  In the following description, it is assumed that the state in which the perforation blades 13 a and 13 b are in contact with the anvil roller 12 in order to process the perforations in the web 3 is the perforation on state, and the web 3 is subjected to perforation processing. A state in which the perforation blades 13a and 13b are separated from the anvil roller 12 so as not to be performed is assumed to be a perforation off state.

  The perforation processing unit 11 includes a perforation blade rotation position information generation unit 13c that outputs rotation position information of the perforation blades 13a and 13b. The sewing blade rotation position information generation unit 13c is configured by a rotary encoder or the like, and outputs a pulse corresponding to the rotation position of the sewing blades 13a and 13b.

  The on / off switching of the sewing machine blades 13a, 13b is performed by the control unit 5 controlling the switching unit 14. This control is performed according to information from the conveyance information generation unit 8 and the sewing blade rotation position information generation unit 13c. Details of the on / off switching operation of the sewing machine blades 13a and 13b by the switching unit 14 will be described later.

  The web 3 that has been subjected to the perforation required in the perforation processing unit 11 is conveyed to the sheet cutter unit 16. At this time, the roller pair 15 provided between the perforation processing unit 11 and the sheet cutter unit 16 can stably supply the web 3 to the sheet cutter unit 16, and By transporting the web 3 without slacking in between, perforation along the transport direction can be formed.

  As the sheet cutter unit 16, for example, a rotary cutter is used. That is, the sheet cutter unit 16 is a cut roller 16a provided with a cutter blade on the surface of a metal drum according to the cut length of the web 3, and a metal cylindrical roller disposed opposite to the cut roller 16a. A certain anvil roller 16b and a resin scraper (not shown) for preventing the sheet cut around the anvil roller 16b from being wound are formed.

  By comprising in this way, the web 3 is continuously cut | disconnected for every page, without stopping the conveyance operation of the web 3 conveyed. In addition, these rollers of the sheet cutter unit 16 are continuously rotated in synchronization with the moving state of the web 3, and the encoder signal count value output in synchronization with the web conveyance distance from the conveyance information generation unit 8. Based on this, the cutting timing is controlled by the control unit 5.

  By performing such control, the sheet cutter unit 16 can cut the continuous web 3 into sheets of a predetermined length, and can perform image recording and cutting operations without reducing the overall throughput.

  Further, the cut sheet is guided so as to sandwich the sheet surface by guides 17 extending in the sheet width direction and provided on the front surface side and the back surface side, and delivered to the discharge roller pair 18, and the discharge unit 19. To be discharged. Note that reference numeral 20 shown in FIG. 1 denotes a paper discharge image detection unit used in the description of an embodiment described later.

  Among the operations of the above units, the image information recorded on the web 3 by the image recording unit 9 and the control information for each job when the perforation processing unit 11 performs perforation processing are transferred from the host device 2 to the control unit 5. Sent.

Next, in the image recording apparatus 1 according to the present embodiment, a process in which the control unit 5 controls the switching unit 14 and the perforation processing unit 11 to perform perforation on / off switching will be specifically described.
FIG. 2 is a diagram specifically illustrating the configuration of the perforation processing unit 11 and the switching unit 14. As shown in the figure, the switching unit 14 includes a cam 22, a link bar 23, a cam follower 24, a tension spring 25, and a cam drive motor (not shown) as main components, and the sewing blades 13a and 13b of the perforation processing unit 11. It is connected to the.

  The sewing blades 13a and 13b are rotatably held at one end of the link bar 23 via a bearing (not shown) so as to face the anvil roller 12 described above. The sewing blades 13 a and 13 b rotate following the conveyance of the web 3 to form a perforation on the web 3.

  The cam follower 24 is fixed to the other end of the link bar 23 so as to face the cam 22. The link bar 23 is attached to be rotatable about a link fulcrum 26. The link bar 23 is urged by a tension spring 25 so that the cam 22 and the cam follower 24 are always in contact with each other.

  FIG. 2A shows the state of the perforation processing unit 11 and the switching unit 14 in the perforation on state, and FIG. 2B shows the state of the perforation processing unit 11 and the switching unit 14 in the perforation off state. In the perforation on state, as shown in FIG. 2 (a), the perforation blades 13a and 13b form the perforations on the web 3 via the link bar 23, so the positions of the perforation blades 13a and 13b are the perforation forming positions. Has moved to. On the other hand, in the perforation off state, as shown in FIG. 2 (b), the positions of the perforation blades 13a and 13b are switched to positions retracted from the perforation forming position.

  The perforation forming position refers to the position of the perforation blades 13a and 13b when the perforation is formed on the web 3 passing between the perforation blades 13a and 13b and the anvil roller 12, as shown in FIG. The positions of the sewing machine blades 13a and 13b shown in FIG.

  The cam 22 is rotated by a cam drive motor (not shown), and a portion that contacts the cam follower 24 is switched to a portion A having a small radius or a portion B having a large radius. That is, a cam drive motor (not shown) is driven to rotate the cam follower 24 having a relationship of (the radius of the A portion <the radius of the B portion) to form a perforation at a predetermined position of the web 3.

  Next, a specific method for forming a perforation at a predetermined position of the web 3 will be described with reference to FIG. Fig.3 (a) shows the front view of the perforation process part 11 and the cutter part 16, and FIG.3 (b) shows the side view.

  As described above, the perforation processing unit 11 includes the anvil roller 12 and the two perforation blades 13a and 13b. The anvil roller 12 is arranged in a direction orthogonal to the conveyance direction of the web 3. Further, the two sewing blades 13 a and 13 b are disposed so as to face the anvil roller 12 with the web 3 interposed therebetween. The anvil roller 12 is disposed at a fixed position in the width direction of the web 3. Further, as described with reference to FIG. 2, the perforating blades 13a and 13b are moved in the perforation on / off switching direction (direction a) shown in FIG.

The web 3 conveyed to the perforation processing unit 11 passes between the anvil roller 12 rotating at the same peripheral speed as the conveyance speed V of the web 3 and the perforating blades 13a and 13b.
The position where the web 3 is on the conveyance path is recognized by counting the conveyance information generated by the control unit 5 in the conveyance information generation unit 8, that is, the periodic pulse generated according to the conveyance distance of the web 3. Is possible. After the image recording is performed by the image recording unit 9, the control unit 5 controls the switching unit 14 so that the sewing blades 13 a and 13 b are turned on / off at a position where a predetermined number of stored pulses are counted.

  As described above with reference to FIG. 2, the switching unit 14 switches the portion of the cam 22 that comes into contact with the cam follower 24 by a cam drive motor (not shown) according to an instruction from the control unit 5. By this control, the perforation processing on / off state is switched, and the perforation is processed at a desired position on the web 3 where the image is recorded.

  As for the number of pulses used here, the number of pulses corresponding to the conveyance path length from the image recording unit 9 to the perforation processing unit 11 is previously stored in a memory or the like as an adjustment value when the image recording apparatus 1 is produced, for example. Remember.

  In the present embodiment, a case where perforation processing is performed in units of pages based on a command from the host device 2 is shown. In the example shown in FIGS. 3A and 3B, the sewing machine blade 13a has n-3 pages (n is a natural number, and n ≧ 4 in the examples of FIGS. 3A and 3B). In this example, the perforations are applied to pages n-2 to n without any perforation. Further, the perforation blade 13b is an example in which the perforation is not performed on the n-1 page and the perforation is performed on the other pages (n-3, n-2, and n pages).

  In accordance with the conveyance information input from the conveyance information generation unit 8, the control unit 5 performs the perforation on / off control at the cutter unit 16 with the cutting scheduled position (virtual line b) as a boundary. Let it form.

  By controlling in this way, it becomes possible to perform suitable perforation according to the recording surface of the sheet | seat which is bound by several sheets according to a use, for example. Furthermore, by applying on / off control of perforation processing for each page, even if the page is to be perforated by a command from the host device 2, there is an abnormality in image quality or image quality. If this is detected, perforation can be turned off.

  In addition, it is good also as a structure which provides the mechanism which moves the sewing machine blades 13a and 13b shown in FIG. 3 with respect to the width direction of the web 3. FIG. By performing movement control of the sewing blades 13a and 13b via a mechanism for moving the sewing blades 13a and 13b in the width direction, perforation can be appropriately performed at a predetermined position in the width direction of the web 3.

Further, in FIGS. 3A and 3B, a configuration in which two sewing blades are provided is shown. However, the present invention is not limited to this configuration. For example, a configuration in which one sewing blade is provided or three or more sewing blades may be provided. A sewing blade may be provided in the width direction of the web 3.
Subsequently, control of perforation processing, which is a feature of the present embodiment, will be described.

  The control unit 5 controls the switching unit 14 so that the sewing blades 13a and 13b are turned on / off. However, in an actual product, the switching timing for each of a plurality of perforations due to dimensional tolerances and assembly tolerances of the cam 22, link bar 23, cam follower 24, sewing machine blades 13a and 13b, and characteristics of a cam drive motor (not shown). Therefore, it is necessary for the control unit 5 to control the switching unit 14 with an individual on / off switching timing signal. For this reason, in a product in which a plurality of perforation switching units are assembled in parallel with the web 3, when only one system has a switching timing from the control unit 5, each perforation machining position with respect to the switching timing instruction Some deviation occurs in

  In many cases, the perforation is controlled on / off according to the cut position (paper edge) of the web 3, so when performing multiple perforations at the same time, adjust the misalignment of the perforation. There is a need to do.

  4 (a) and 4 (b) both show a standby state before perforation machining. The different part is the distance (angle) to the switching step between the A part and the B part of the cam 22 in contact with the cam follower 24. Comparing the standby position of the cam 22 shown in FIGS. 4A and 4B, when the angle θ1 <angle θ2, and the switching unit 14 receives a control signal from the control unit 5 at the same time, FIG. ) Can make the contact timing of the sewing machine blades 13a and 13b earlier than in FIG. 4B. By appropriately adjusting the angles θ1 and θ2, the perforation processing start position on the web 3 due to the dimensional tolerance and assembly tolerance of each part of the perforation machining portion is accurately set to the cut position (paper edge) of the web 3 It becomes possible to fit in. Therefore, it is possible to match the machining start timings of the plurality of perforated machining portions.

  Next, FIGS. 5A and 5B will be described. In both figures, the switching unit 14 is driven by the control signal from the control unit 5 so that the cam 22 is rotationally driven and the sewing blades 13 a and 13 b are brought into contact with the web 3. The different part is the distance (angle) to the switching step between the A part and the B part of the cam 22 in contact with the cam follower 24.

  Comparing the stop position of the cam 22 shown in FIGS. 5A and 5B, the angle θ4> the angle θ3, and when the switching unit 14 receives the control signal from the control unit 5 at the same time, FIG. The retract timing of the sewing machine blades 13a and 13b can be made earlier in (a) than in FIG. 5 (b). The angles θ3 and θ4 are angles determined by the cam angle feed amount from the standby position before the sewing blades 13a and 13b contact each other. This means that if the cam angle feed amount from the standby position is large, the retreat time after the sewing blades 13a, 13b contact the web 3 is shortened.

Conversely, if the cam angle feed amount from the standby position is small, it means that the retreat time after the sewing blades 13a, 13b contact the web 3 becomes long. Therefore, by appropriately adjusting the angle θ3 and the angle θ4, the perforation processing end position on the web 3 due to the dimensional tolerance of each part of the perforation processing portion and the assembly tolerance is the cut position of the web 3 (paper edge). It becomes possible to adjust to exactly. Therefore, it is possible to match the end timings of the plurality of perforated portions.
In the above description, the cam 22 has been described as rotating only in one direction, but it is needless to say that the cam 22 may be controlled in both directions to satisfy the embodiment of the present invention.
As described above, in the first embodiment of the present invention, each of the plurality of perforation processing units includes independent drive units, and the timing of the plurality of perforation processing units is finely adjusted by one timing signal from the control unit 5. In order to make the adjustment possible, the start and end timings of the plurality of perforations can be matched.

Next, a second embodiment of the present invention will be described.
As a second embodiment, an image recording apparatus in which a paper discharge image detection unit 20 that detects an image downstream of the perforation processing unit 11 in the web conveyance direction will be described. Here, only differences from the first embodiment will be described. That is, the image recording apparatus of the present embodiment also includes the medium storage unit 4, the control unit 5, the drum 6, the image recording unit 9, the switching unit 14, and the like, and the control unit 5 performs control according to a command from the host apparatus 2, The configuration in which image information is recorded by the image recording unit 9 on the web 3 conveyed on the drum 6 is the same as in the above-described embodiment.

  FIG. 6 is a schematic layout diagram after the perforation processing unit 11 in the second embodiment. The perforation generated on the web 3 by the perforation processing unit 11 is cut by the cutter unit 16 in a direction orthogonal to the conveyance direction. The web 3 that has been cut to a predetermined size is detected at the start and end positions of the perforation by the paper discharge image detection unit 20 installed immediately after the guide 17.

  For example, an image sensor is used for the discharged image detection unit 20, and the perforation generated on the web 3 is detected by the perforation processing unit 11. The perforation position deviation information from the cut position (paper edge) of the web 3 detected by the discharged image detection unit 20 is used by the control unit 5 to adjust the control timing of the perforation processing unit 11.

Based on the positional deviation information detected above, the cam 22 standby position and the cam angle feed amount during the abutting operation of the sewing blades 13a and 13b are changed, and the perforation is always set to the cut position (paper end) of the web 3. The start position and the end position are adjusted so as to be generated.
From the above, also in the second embodiment of the present invention, the timings of the plurality of perforation machining units can be finely adjusted by the one timing signal from the control unit 5, so It becomes possible to match.

As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be made without departing from the scope of the present invention. It is. For example, some constituent elements may be deleted from the overall configuration shown in each of the above-described embodiments, and different constituent elements of the respective embodiments may be combined as appropriate.
