The pair of side plates 82 and the pair of side plates 74 have the same plate thickness, and form a flush state (a state without a step) (see FIG. 7). Further, in a state where the support portion 80 supports the wound mechanism 70, the through hole 86A of the second connecting portion 86 overlaps the through hole 76C of the wound mechanism 70 in the apparatus height direction.

  The rotation shaft 89 is rotatably fitted in the through holes 76C and 86A that overlap in the apparatus height direction. Further, the lower end of the rotation shaft 89 is fixed to a frame (not shown) in the image forming apparatus 10 (see FIGS. 4 and 5).

  The support unit 80 other than the rotating shaft 89 supports the wound mechanism 70, and when the longitudinal direction of the wound plate 72 is 0 ° along the apparatus depth direction, As an example, it is possible to rotate within a range of -1 ° to 1 °. The support portion 80 is in a state in which the angle is in the range of −1 ° or more and 1 ° or less around the axis of the rotation shaft 89, and a bolt and a nut ( It is positioned and fixed by (not shown).

  As described above, the rotary shaft 89 and the wound mechanism 70 of the present embodiment are configured, the connecting portion 76 where the through hole 76C is formed, and the support portion 80 are configured, and the through hole 86A is formed. The combination of the two connecting portions 86 (hereinafter, referred to as the adjustment portion AM) has a function of adjusting the inclination of the side around which the medium P of the to-be-wrapped plate 72 is wound with respect to the apparatus depth direction (X direction side in the apparatus width direction). Have. In other words, the adjustment unit AM has a function of inclining the wound mechanism 70 to adjust the amount of protrusion of the other end of the wound plate 72 toward the side on which the medium P is wound with respect to one end in the longitudinal direction. Have.

  As described above, the support portion 80 constitutes the adjustment mechanism 60 together with the wound mechanism 70. As shown in FIG. 6, the two overhang portions 82 </ b> B <b> 1 are viewed in the apparatus depth direction from the conveyance path of the medium P (the end on the −X direction side in the apparatus width direction of the wrapped plate 72) when viewed from the apparatus depth direction. It protrudes to the -X direction side. Therefore, during the image forming operation, when the medium P transported by the transport mechanism 50 is skewed to the near side in the apparatus depth direction and comes into contact with the two overhanging portions 82B1, the two overhanging portions 82B1 It is designed not to move further to the near side in the apparatus depth direction than the part 82B1. That is, each overhang portion 82B1 has a function of restricting the movement of the medium P toward the front side (one end side) in the apparatus depth direction. Here, each overhang portion 82B1 is an example of a limiting member.

  The above is the description of the configuration of the adjustment mechanism 60 of the present embodiment.

[Quality engineering experiment on tilt of roll plate and height and tilt angle of tilt roll]
As described above, the adjusting mechanism 60 of the present embodiment can adjust the inclination of the wound plate 72 by rotating the wound mechanism 70 supported by the support portion 80 about the rotation shaft 89. Further, in the adjustment mechanism 60 of the present embodiment, the inclination angle of the inclined roll 78 is set by the first link mechanism 110, and the protruding height of the plurality of inclined rolls 78 with respect to the wrapped plate 72 (the arc surface thereof) by the second link mechanism 120. Can be adjusted. Hereinafter, the relationship between the above three adjustments and bringing the medium P closer to the front side in the apparatus depth direction will be described with reference to the results of quality engineering experiments in FIGS. 10 (A) and 10 (B).

The quality engineering experiment was performed using the image forming apparatus 10 as follows. First, as an initial state of the adjustment mechanism 60, the inclination angle of the winding plate 72 with respect to the apparatus depth direction is set to 0 °, and the protruding heights of the plurality of inclined rolls 78 with respect to the winding plate 72 (the arc surface thereof) are set to 1 mm. The tilt angle of the tilt roll 78 was 10 °. The medium P was transported by the transport mechanism 50 in the transport direction at a transport speed of 40 m / min. Thereafter, the skew acceleration mm / s ² of the medium P was measured by changing the tilt angle of the winding plate 72, the protruding height of the tilt roll 78, and the tilt angle of the tilt roll 78. In this case, in each adjustment, the inclination angle of the winding plate 72 is −1 °, 0 ° and 1 °, the protruding height of the inclined roll 78 is 0.5 mm, 1 mm and 1.5 mm, and the inclination angle of the inclined roll 78. Were 5 °, 10 ° and 15 °. In addition, the inclination angle of the to-be-wrapped plate 72 is -1 °, and the end on the far side of the to-be-wrapped plate 72 protrudes in the X direction in the device width direction from the end on the near side in the device depth direction. This is a state in which the angle between the longitudinal direction of the wrapped plate 72 and the apparatus depth direction is 1 °. Here, the skew acceleration of the medium P indicates the speed at which the medium P moves in the apparatus depth direction per unit time. A positive skew acceleration indicates a case where the medium P moves from the back side to the near side in the apparatus depth direction, and a negative skew acceleration indicates the opposite case.

  FIG. 10A shows the result (factor effect diagram) of the quality engineering experiment in the case where the medium P is transported by the transport mechanism 50 with the adjusting mechanism 60 in the initial state, and the medium P tends to skew positively. Show. On the other hand, FIG. 10B shows the result of a quality engineering experiment when the medium P is conveyed by the conveyance mechanism 50 with the adjustment mechanism 60 in the initial state, and the medium P tends to be skewed negatively ( Factor effect diagram).

  According to FIG. 10A, the sensitivity of the skew acceleration by adjusting the tilt angle of the wrapped plate 72 is higher than the protrusion height of the tilt roll 78 and the sensitivity of the tilt angle. Further, according to FIG. 10B, the sensitivity of the tilt angle of the wound plate 72 is higher than the protrusion height of the tilt roll 78 and the sensitivity of the tilt angle. That is, the inventor of the present application has found that the medium P can largely adjust the positive or negative skew acceleration by adjusting the inclination angle of the wound plate 72. Further, the inventor of the present application has found that the medium P can be adjusted (finely adjusted) to make the positive or negative skew acceleration small by adjusting the protruding height and the inclined angle of the inclined roll 78.

<Adjustment method of adjustment mechanism>
Next, an adjustment method of the adjustment mechanism 60 found by the inventors of the present application based on the results of the quality engineering experiment described above will be described. The adjustment of the adjustment mechanism 60 according to the present embodiment is performed by an operator when the image forming apparatus 10 is shipped, when the image forming apparatus 10 is installed, when the medium P is changed, and the like.

[When medium P skews to the near side in the apparatus depth direction]
This case corresponds to, for example, the case of FIG. When the medium P is transported in this state, the medium P is skewed and comes into contact with the protruding portion 82B1, and the near end of the medium P in the apparatus depth direction may be buckled. Further, the medium P may be skewed to the near side in the apparatus depth direction, and an image formed by the head 20 may be shifted in the width direction of the medium P.

  First, the operator uses the support portion 80 of the adjustment mechanism 60 so that the medium P is conveyed without being skewed, so that the end on the far side with respect to the end on the near side in the apparatus depth direction of the wrapped plate 72 Adjust the amount of protrusion at the end on the back side so that the portion protrudes to the side around which the medium P is wound (first adjustment).

  Next, the operator increases the inclination angle of each inclined roll 78 with the first link mechanism 110 and decreases the protruding height of each inclined roll 78 with the second link mechanism 120 or the first link mechanism. 110 and the second link mechanism 120 are used to finely adjust the inclined roll 78 so that the inclined angle of the inclined roll 78 is increased and the protruding height is decreased so that the medium P to be conveyed is positioned at a predetermined position (second adjustment). .

  Thus, the adjustment operation when the medium P is skewed to the near side in the apparatus depth direction is completed. Note that, as a result of the first adjustment, when the medium P to be conveyed is located at a predetermined position, the second adjustment is not performed (it is not necessary to perform).

[When the medium P skews to the far side in the apparatus depth direction]
This case corresponds to, for example, the case of FIG. If the medium P is transported in this state, the medium P may be skewed to the back side in the apparatus depth direction, and an image formed by the head 20 may be shifted in the width direction of the medium P.

  First, the operator uses the support portion 80 of the adjustment mechanism 60 so that the medium P is conveyed without skew, and the end on the near side with respect to the end on the far side in the apparatus depth direction of the wrapped plate 72. Adjust the amount of protrusion at the end on the near side so that the portion protrudes toward the side on which the medium P is wound (first adjustment).

  Next, the operator increases the inclination angle of each inclined roll 78 with the first link mechanism 110 and decreases the protruding height of each inclined roll 78 with the second link mechanism 120 or the first link mechanism. The inclination angle of each inclined roll 78 is increased and the protruding height is decreased by 110 and the second link mechanism 120, and fine adjustment is performed so that the medium P to be conveyed is positioned at a predetermined position.

  Thus, the adjustment operation in the case where the medium P is skewed to the back side in the apparatus depth direction is completed. Note that, as a result of the first adjustment, when the medium P to be conveyed is located at a predetermined position, the second adjustment is not performed (it is not necessary to perform).

  The above is the description of the adjustment method of the adjustment mechanism 60 of the present embodiment.

≪Action≫
Next, the operation of this embodiment will be described.

<First action>
The first effect is that the inclination of the wound plate 72 is adjustable. Hereinafter, the first action will be described with reference to the drawings while comparing the first embodiment with the first comparative embodiment described below. In addition, when using the components used by this embodiment in the 1st comparative form, the code | symbol, name, etc. of the components shall be used as it is.

  The support portion 80 of the adjustment mechanism (not shown) of the first comparative form does not include the rotation shaft 89. The adjustment mechanism of the first comparative embodiment is fixed to the casing of the image forming apparatus 10 with the longitudinal direction of the wrapped plate 72 extending in the apparatus depth direction. The adjustment mechanism, the transport device, and the image forming apparatus of the first comparative embodiment have the same configurations as the adjustment mechanism 60, the transport device 30, and the image forming apparatus 10 of the present embodiment except for the above points.

  In the case of the first comparative embodiment, the inclination of the wound plate 72 cannot be adjusted. Therefore, when the medium P to be transported skews to the near side or the far side in the apparatus depth direction, the direction in which the medium P is skewed by adjusting one or both of the tilt angle and the protruding height of each tilt roll 78. And skew in the opposite direction. However, in the case of the first comparative embodiment, even if the inclination angle and the protruding height of each inclined roll 78 are adjusted to skew the medium P in the reverse direction, the skew force in the reverse direction is not sufficient. There are cases where the skew cannot be stopped.

  On the other hand, in the case of this embodiment, unlike the case of the first comparative embodiment, the inclination of the wrapped plate 72 can be adjusted (see FIGS. 4 and 5). Further, as described above, the sensitivity of the inclination angle of the wound plate 72 is higher than the protrusion height of the inclined roll 78 and the sensitivity of the inclination angle (see FIGS. 10A and 10B). Therefore, in the case of this embodiment, since the inclination of the to-be-wrapped board 72 can be adjusted, it is easier to stop the skew of the medium P than in the case of the first comparative embodiment.

  Therefore, according to the adjustment mechanism 60 of the present embodiment, compared to the case where the inclination of the side on which the medium P is wound with respect to the apparatus depth direction of the wound plate 72 cannot be adjusted, the conveyed medium P in the apparatus depth direction. Misalignment can be suppressed (the medium P to be conveyed is easily positioned at a predetermined position). Accordingly, according to the transport device 30 of the present embodiment, it is possible to suppress the transport failure due to the positional deviation as compared with the case where the inclination of the wrapped plate 72 with respect to the device depth direction cannot be adjusted. In addition, according to the image forming apparatus 10 of the present embodiment, it is possible to suppress the image formation defect due to the conveyance failure as compared with the case where the inclination of the winding plate 72 with respect to the apparatus depth direction cannot be adjusted. Here, the image formation failure due to the conveyance failure means that the image is formed with a deviation in the width direction of the medium P because the medium P is skewed in the apparatus depth direction.

<Second action>
The second effect is that the protrusion height of the plurality of inclined rolls 78 with respect to the winding plate 72 (the arc surface thereof) is based on the assumption that the inclination of the winding plate 72 with respect to the apparatus depth direction can be adjusted. This is an effect of being adjustable. Hereinafter, the second operation will be described with reference to the drawings while comparing the second embodiment with the second comparative embodiment described below. In addition, when using the component etc. which were used by this embodiment in the 2nd comparative form, the code | symbol, name, etc. of the component shall be used as it is.

  The adjustment mechanism (not shown) of the second comparative form does not include the link mechanism 100. The adjustment mechanism, the conveyance device, and the image forming apparatus of the second comparative embodiment have the same configurations as the adjustment mechanism 60, the conveyance device 30, and the image forming apparatus 10 of the present embodiment except for the above points.

  The adjustment mechanism of the second comparative form is capable of adjusting the inclination of the wrapped plate 72. For this reason, the adjustment mechanism, the transport device, and the image forming apparatus of the second comparative form are the forms that exhibit the first action described above, and therefore the adjustment mechanism, the transport apparatus, and the image forming apparatus of the second comparative form are the present invention. Belongs to the technical scope of

  The adjustment mechanism of the second comparative form cannot finely adjust the position of the medium P to be conveyed in the apparatus depth direction by adjusting one or both of the protrusion height and the inclination angle of the inclined roll 78.

  On the other hand, the adjustment mechanism 60 of the present embodiment includes the first link mechanism 110 (see FIG. 6). Therefore, in the case of the present embodiment, the first link mechanism 110 is used to change the inclination angle of the inclined roll 78 with respect to the transport direction of the medium P, and finely adjust the position of the transported medium P in the apparatus depth direction. (See FIGS. 6 and 8). Further, the adjustment mechanism 60 of the present embodiment includes a second link mechanism 120. Therefore, in this embodiment, the second link mechanism 120 is used to change the protruding height of the plurality of inclined rolls 78 with respect to the wrapped plate 72 (the arc surface thereof), and the device depth of the medium P to be conveyed. The position in the direction can be finely adjusted (see FIGS. 6 and 9). Further, in the case of the present embodiment, the first link mechanism 110 and the second link mechanism 120 are used, and the inclination angle of the inclined roll 78 with respect to the conveyance direction of the medium P and a plurality of inclinations with respect to the winding plate 72 (the arc surface thereof). By changing the protruding height of the roll 78, the position of the conveyed medium P in the apparatus depth direction can be finely adjusted (see FIG. 6). In other words, in the case of the present embodiment, the skew angle of the medium P is different by adjusting or adjusting the inclination angle of the winding plate 72 and the protrusion height and inclination angle of the inclined roll 78 in combination. Corresponding to the types of media P, it is possible to transport different types of media P in a state where they are located at predetermined positions in the apparatus depth direction.

  Therefore, according to the adjustment mechanism 60 of the present embodiment, it is easy to finely adjust the position of the medium P to be conveyed in the apparatus depth direction, compared to the case where the protruding height of the inclined roll 78 with respect to the wrapped plate 72 cannot be adjusted. Can be done. Further, according to the adjustment mechanism 60 of the present embodiment, the position of the medium P to be conveyed in the apparatus depth direction can be finely adjusted more easily than when the inclination angle of the inclined roll 78 with respect to the medium P conveyance direction cannot be adjusted. It can be carried out.

<Third action>
The third function is that the adjusting mechanism 60 is arranged on the upstream side in the transport direction of the medium P with respect to the head 20. Hereinafter, the third action will be described with reference to the drawings while comparing the third embodiment with the third comparative embodiment described below. In addition, when using the components etc. which were used by this embodiment in the 3rd comparison form, the numerals, names, etc. of the components shall be used as they are.

  In the image forming apparatus (not shown) of the third comparative embodiment, the adjustment mechanism 60 is disposed on the downstream side in the transport direction of the medium P with respect to the head 20. The image forming apparatus of the third comparative embodiment has the same configuration as that of the image forming apparatus 10 of the present embodiment except for the above points.

  Note that the configuration of the adjustment mechanism 60 itself of the image forming apparatus of the third comparative embodiment is the same as that of the adjustment mechanism 60 of the present embodiment. For this reason, since the image forming apparatus of the third comparative embodiment has the above-described first action, the image forming apparatus of the third comparative embodiment belongs to the technical scope of the present invention.

  As described above, the adjustment mechanism of the third comparative embodiment is arranged on the downstream side of the head 20 in the transport direction of the medium P as described above. Therefore, in the case of the third comparative embodiment, the medium P is determined in the apparatus depth direction unless it is after the medium P has been transported to the adjusting mechanism 60 disposed downstream of the head 20 in the transport direction of the medium P. The position is not reached.

  On the other hand, in the case of the present embodiment, the adjustment mechanism 60 is disposed upstream of the head 20 in the transport direction of the medium P, as shown in FIGS.

  Therefore, according to the image forming apparatus 10 of the present embodiment, the position of the medium P in the apparatus depth direction as compared with the case where the adjustment mechanism 60 is disposed downstream of the head 20 in the conveyance direction of the medium P. The transport length of the medium P transported before the deviation is suppressed is short. In other words, in the case of the image forming apparatus 10 according to the present embodiment, compared with the case where the adjustment mechanism 60 is disposed on the downstream side in the transport direction of the medium P with respect to the head 20, the adjustment mechanism 60 is wasteful in the adjustment operation. It can be said that the length of the medium P to be made is short.

  As described above, the present invention has been described in detail with respect to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various other embodiments are possible within the scope of the present invention. .

  For example, the image forming apparatus 10 according to the present embodiment has been described as having one head 20 (see FIGS. 1, 2, and 3). However, an image forming apparatus that forms a multicolor image using a plurality of heads 20 may be used.

  Further, the medium P whose position in the apparatus depth direction is adjusted by the adjusting mechanism 60 of the present embodiment has been described as pin feed paper as an example of a continuous medium. However, as shown in FIG. 1, a flexible medium that is transported integrally (continuously) over the transport path is not paper, but resin, metal, a composite material thereof, or other possible materials. A flexible medium may be used.

  Moreover, in description of this embodiment, the to-be-wrapped board 72 is -1 degree-1 degree with respect to an apparatus depth direction, the inclination angle of the some inclination roll 78 is the range which is 5 degrees or more and 15 degrees or less, a some inclination roll. It has been described that the protrusion height of 78 can be adjusted in a range of −1 mm or more and 2 mm or less with respect to the winding plate 72 (the arc surface thereof). However, these ranges are merely examples, and may be adjusted in different ranges.

  The adjustment mechanism 60 of the present embodiment includes a first link mechanism 110 that adjusts the inclination angle of the inclined roll 78, a second link mechanism 120 that adjusts the protruding height of the inclined roll 78 with respect to the wrapped plate 72, and It was explained as having. However, as long as the inclination of the to-be-wrapped plate 72 of the adjustment mechanism 60 can be adjusted, either one or both of the first link mechanism 110 and the second link mechanism 120 may not be provided. Even if the adjustment mechanism does not include the first link mechanism 110 and the second link mechanism 120, the inclination of the wound plate 72 can be adjusted. It goes without saying that the effects of

  Further, in the adjustment mechanism 60 of the present embodiment, the rotation shaft 89 is a through hole formed in the center in the longitudinal direction of the connecting portion 76 and a through hole formed in the center in the longitudinal direction of the second connecting portion 86. It has been described that it is rotatably fitted to 86A to adjust the inclination of the wrapped plate 72 with respect to the apparatus depth direction. However, if the inclination with respect to the apparatus depth direction of the to-be-wrapped board 72 can be adjusted, the connection part 76 and the 2nd connection part 86 do not need to rotate centering on a longitudinal direction. For example, the connecting portion 76 and the second connecting portion 86 may rotate around a portion shifted from the center in the longitudinal direction.

  Further, the adjustment mechanism 60 of the present embodiment has been described as adjusting the inclination of the wound plate 72 by rotating around the rotation shaft 89. However, as long as the inclination with respect to the apparatus depth direction of the to-be-wrapped board 72 can be adjusted, the system to rotate the to-be-wrapped board 72 around the rotating shaft 89 may not be used. For example, in the apparatus width direction, a pair of stoppers are disposed at both ends in the longitudinal direction of the winding plate 72 while urging the side opposite to the side where the winding plate 72 of the adjustment mechanism 60 is disposed, You may make it adjust the inclination of the to-be-wrapped board 72 by adjusting the position of a pair of stopper.

  Further, the image forming apparatus 10 of the present embodiment has been described as an inkjet apparatus (see FIGS. 1, 2 and 3). However, the image forming apparatus may not be an inkjet apparatus as long as it is an apparatus that forms images by transporting continuous paper with the transport device 30. For example, the image forming apparatus belonging to the technical scope of the present invention may be an electrophotographic image forming apparatus, a flexographic image forming apparatus, or other image forming apparatuses.

  Further, the conveying apparatus 30 of the present embodiment has been described as constituting the image forming apparatus 10 (see FIGS. 1 and 2). However, if the conveying device 30 is a device that conveys the medium P, the conveying device 30 may not constitute the image forming apparatus 10. For example, the transport device 30 may be a device for transporting the medium P and laminating another material different from the medium P such as a film on the medium P. Further, the transport device 30 may be a device that constitutes a cutting device and transports the medium P to be cut.
