Description

  The present invention relates to a method for manufacturing a conveyor belt.

  In an ink jet printer, recording is performed on a medium by ejecting ink from the ink jet head onto the medium while conveying a medium such as paper. As a means for transporting the medium, a transport belt stretched around a roller is used (see, for example, Patent Document 1).

JP 2006-347039 A

  Meanwhile, a high friction layer and a magnetic encoder layer for generating a frictional force with the medium are formed on the surface of the conveyor belt. However, in the process of manufacturing a conventional conveyor belt, a high friction layer or There was a possibility of unevenness in the magnetic encoder layer. If unevenness occurs in the high friction layer, the flatness of the belt body is lowered, and the print quality is lowered. In addition, when unevenness occurs in the magnetic encoder layer, good reading cannot be performed, and as a result, the print quality deteriorates.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a method of manufacturing a transport belt that can satisfactorily transport a medium by preventing unevenness due to a manufacturing process.

  In order to solve the above-described problem, a method for manufacturing a transport belt according to the present invention is a method for manufacturing a transport belt that places and transports a medium, and a fluid is ejected from a nozzle of a fluid ejecting head to one side of the belt body.

And

  According to the method for manufacturing a transport belt of the present invention, it is possible to form a functional layer having a concavo-convex pattern composed of a plurality of convex portions arranged along a direction orthogonal to the circumferential direction of the belt main body. For example, when the functional layer is used as a friction layer on the belt main body, the convex portions of the concavo-convex pattern constituting the functional layer extend in the non-orthogonal direction with respect to the circumferential direction of the belt main body. Periodic unevenness caused by the can be reduced. Therefore, a decrease in flatness of the medium placed on the functional layer is prevented, and a transport belt that can transport the medium satisfactorily can be manufactured. Further, for example, when the functional layer is used as a base layer of the encoder layer, periodic unevenness becomes noise and the reading quality of the encoder is not deteriorated, and a transport belt capable of transporting the medium satisfactorily can be obtained.

Further, in the method of manufacturing the transport belt, in the functional layer forming step, the fluid ejecting head is moved in the width direction of the belt body in conjunction with the rotation operation of the belt body, and the nozzle is moved from the nozzle. Preferably the fluid is ejected.
According to this configuration, since the fluid ejecting head is moved in the width direction of the belt body in conjunction with the rotation operation of the belt body, the plurality of convex portions arranged along the non-orthogonal direction with the circumferential direction of the belt body are provided. It can be easily and reliably formed.

Further, in the method for manufacturing the transport belt, in the functional layer forming step, the fluid ejecting head is moved in a non-orthogonal direction with respect to the circumferential direction of the belt body while the rotation operation of the belt body is stopped. The fluid is preferably ejected from the nozzle.
According to this configuration, it is possible to satisfactorily form the convex portion along the predetermined direction by moving the fluid ejecting head directly inclined with respect to the belt main body. Further, when forming the convex portion, it is only necessary to drive the fluid ejecting head, so that the control can be simplified.

Moreover, in the manufacturing method of the said conveyor belt, it is preferable to form the said uneven | corrugated pattern by changing the direction of the said relative movement in the middle of the circumferential direction of the said belt main body in the formation process of the said functional layer.
According to this configuration, it is possible to form a functional layer having a plurality of concavo-convex patterns in which the extending directions of the respective convex portions are different, and thus it is possible to provide a transport belt in which periodic unevenness caused by the convex portions is further reduced.

Moreover, in the manufacturing method of the said conveyance belt, it is preferable to form the friction layer which produces a frictional force between the said media as said functional layer.
According to this configuration, it is possible to provide a belt that can reduce the periodic unevenness caused by the convex portions of the friction layer as described above and can transport the medium while maintaining good flatness.

Moreover, in the manufacturing method of the said conveyance belt, it is preferable to form an encoder as said functional layer.
According to this configuration, it is possible to provide a conveyor belt in which the encoder reading performance is prevented from being deteriorated due to periodic unevenness as described above.

  Here, the configuration of the high μ layer 10, which is a characteristic configuration of the conveyor belt 23, will be described with reference to FIGS. 3A is an enlarged view showing a planar shape of the high μ layer 10, and FIG. 3B is a perspective enlarged view showing the configuration of the high μ layer 10. In addition, illustration of the magnetic encoder 12 is abbreviate | omitted in FIG. 3 (a), (b). 4A is a diagram showing a planar shape of the magnetic encoder 12, and FIG. 4B is an enlarged perspective view showing the configuration of the magnetic encoder 12. FIG. 4A and 4B, the illustration of the high μ layer 10 is omitted.

  The high μ layer 10 has a concavo-convex pattern 70 formed by an ink jet method to be described later as shown in FIGS. The concavo-convex pattern 70 includes a plurality of convex portions 71 extending along one direction (the direction indicated by the symbol A in FIG. 3A) and arranged substantially in parallel, and the plurality of convex portions. And a recess 72 provided between the two. The uneven pattern 70 (high μ layer 10) is made of, for example, a material having a high friction coefficient (for example, polyurethane paint).

That is, the concavo-convex pattern 70 is configured by regularly arranging the convex portions 71 and the concave portions 72. Specifically, the convex portion 71 extends along a non-orthogonal direction with respect to the circumferential direction of the belt main body 50 that forms the base material of the transport belt 23. In the present embodiment, the convex portion 71 is 45 with respect to a direction orthogonal to the circumferential direction of the belt main body 50 (X direction shown in FIG. 3A) (Y direction shown in FIG. 3A). It extends at an angle theta ₁ of °.

  As shown in FIGS. 4A and 4B, the magnetic encoder 12 has a magnetic layer 12a composed of a concavo-convex pattern 80 formed by an ink jet method described later. The concavo-convex pattern 80 (magnetic layer 12a) extends along one direction (the direction indicated by the symbol B in FIG. 4A) and has a plurality of convex portions 81 that are arranged substantially in parallel with each other, And a concave portion 82 provided between the plurality of convex portions 81. The magnetic encoder 12 is configured by writing magnetism in the magnetic layer 12a (uneven pattern 80) as described later.

That is, the concavo-convex pattern 80 is configured by regularly arranging the convex portions 81 and the concave portions 82. Specifically, the convex portion 81 extends along a circumferential direction (X direction in FIGS. 4A and 4B) and a non-orthogonal direction of the belt main body 50 that forms the base material of the transport belt 23. Specifically, in the present embodiment, the protrusion 81 is in a direction orthogonal to the circumferential direction of the belt main body 50 (X direction shown in FIG. 4A) (Y direction shown in FIG. 3A). It extends so as to form a 155 ° angle theta ₂ Te. That is, the extending direction of the convex portion 81 of the magnetic encoder 12 is in a state orthogonal to the extending direction of the convex portion 71 of the high μ layer 10 (the direction indicated by the symbol A).

Next, a method for manufacturing the conveyor belt 23 will be described with reference to FIGS.
First, as shown in FIG. 5A, the belt main body 50 serving as the base material of the conveyor belt 23 is wound around the processing main driving roller 62 and the processing driven roller 63. The belt main body 50 is configured by welding a sheet-like member made of, for example, polyethylene terephthalate (PET).

  Subsequently, predetermined processing for forming the conveyor belt 23 is performed on the belt main body 50. In the present embodiment, a plurality of processing processes, for example, three processing processes are performed as the predetermined processing. The first processing process is a process for applying a frictional force to the surface 50 a of the belt main body 50. The second processing process is a drilling process for forming the suction holes 11 in the belt body 50. The third processing process is a process for forming the magnetic encoder 12 on the side portion of the belt main body 50.

Hereinafter, the processing will be specifically described.
First, as shown in FIGS. 5A and 5B, the main driving roller 62 and the driven roller 63 for processing are rotated by a driving mechanism (not shown) to rotate the belt main body 50, and the inkjet main body is rotated. A liquid body (fluid) 71a containing a material (for example, polyurethane paint) having a high friction coefficient is ejected from the nozzle 5a of the head (fluid ejecting head) 5 onto the surface (one surface) 50a of the belt main body 50 to be unidirectional. The high μ layer 10 having the concavo-convex pattern 70 in which each of the plurality of extending protrusions 71 is arranged substantially in parallel is formed.

  Specifically, in the present embodiment, the ink jet head (fluid ejecting head) 5 is moved in the width direction of the belt main body 50 (Y direction in FIG. 5B) in conjunction with the rotation operation of the belt main body 50, and the nozzle The liquid material is discharged from 5a. Thus, the liquid material discharged from the nozzle 5a is arranged along the circumferential direction (X direction in the figure) and the non-orthogonal direction of the belt main body 50 (specifically, in this embodiment, as shown in FIG. 3A). The belt body 50 is arranged at an angle of 45 ° with respect to the width direction of the belt main body 50).

  By repeating the above operation, the liquid material is applied to the entire surface 50a of the belt main body 50. Then, the liquid material is dried to form convex portions 71 and concave portions 72 on the surface 50 a of the belt main body 50. Therefore, the surface 50a of the belt main body 50 is provided with a concavo-convex pattern 70 in which convex portions 71 and concave portions 72 are regularly arranged in a predetermined direction, as shown in FIGS. A high μ layer 10 is formed (first processing).

  After the high μ layer is formed on the surface 50a of the belt main body 50, the belt main body 50 is rotated and moved to the belt main body 50 by the mold 9 as shown in FIGS. 6 (a) and 6 (b). A through hole is formed to be a suction hole 11 (second processing). In FIGS. 6A and 6B, the high μ layer 10 formed on the belt main body 50 is simplified for easy understanding of the drawings.

  The suction hole 11 sucks, for example, the surface 50a side of the belt main body 50. In addition, the air blowing device 7 is disposed above the processing main driving roller 62 and air is blown against the belt main body 50 to remove foreign matter adhering to the suction holes 11 and the belt main body 50.

After the suction holes 11 are formed in the belt main body 50, as shown in FIG. 7A and FIG. 7B, the magnetic body is formed by the ink jet head (fluid ejecting head) 8 while the belt main body 50 is rotationally moved. The material is discharged to form the magnetic layer 12 a on the side of the belt body 50. In the present embodiment, similarly to the high μ layer 12, the magnetic material is discharged from the nozzle 5 a while moving the inkjet head 8 in the width direction of the belt body 50 in conjunction with the rotation operation of the belt body 50. Thereby, the magnetic material discharged from the nozzle 8a is arranged along the circumferential direction (X direction in the figure) and the non-orthogonal direction of the belt main body 50. In the present embodiment, the magnetic material is along a direction (a direction perpendicular to the extending direction of the convex portion 71) that forms an angle θ _{2 of} 155 ° with respect to the width direction of the belt body 50 (Y direction in the figure). Arrange.
Then, magnetism (N pole, S pole) is written to the magnetic layer 12a formed as described above using a magnetic write head. Thereby, the magnetic encoder 12 can be formed in the side part of the belt main body 50 (3rd processing process). In this way, the conveyance belt 23 having the high μ layer 10, the suction holes 11 and the magnetic encoder 12 is formed.

  By the way, when the high μ layer (uneven pattern 70) 10 is formed by discharging the liquid from the inkjet head 5, a slight coating unevenness occurs between the protrusions 71. Therefore, when the convex portion 71 extends in a direction orthogonal to the circumferential direction of the belt main body 50, the convex portion 71 is regularly arranged along the circumferential direction (rotational direction) of the conveyor belt 23. Due to the periodic unevenness (periodic unevenness) caused by the convex portion 71, the flatness of the recording paper P placed on the transport belt 23 may be reduced, and the print quality may be deteriorated.

  Similarly, when the magnetic layer 12 a (uneven pattern 80) is formed by discharging a magnetic material from the inkjet head 8, coating unevenness slightly occurs between the convex portions 81. Therefore, when the convex portion 81 extends in a direction orthogonal to the circumferential direction of the belt main body 50, the convex portion 81 is regularly arranged along the circumferential direction (rotational direction) of the transport belt 23. . When such a magnetic encoder 12 is read by a contact-type sensor, the periodic unevenness (periodic unevenness) caused by the convex portion 81 may become noise and the reading quality of magnetism written in the magnetic layer 12a may deteriorate. is there.

  On the other hand, according to the conveyor belt 23 manufactured by the above method, the convex portions 71 constituting the concavo-convex pattern 70 are not orthogonal to the circumferential direction of the belt main body 50 (in this embodiment, in the width direction of the belt main body 50). It extends along a direction that forms an angle of 45 ° with respect to. Further, the convex portions 81 constituting the concavo-convex pattern 80 extend along a direction orthogonal to the circumferential direction of the belt main body 50 (in this embodiment, a direction forming an angle of 155 ° with respect to the width direction of the belt main body 50). Will be. Therefore, unevenness caused by the convex portions 71 and the convex portions 81 generated in the conveyance direction of the recording paper P can be dispersed. Therefore, it is possible to prevent the flatness of the recording paper P placed on the concave / convex pattern 70 from being lowered, and good printing can be performed on the recording paper P. Furthermore, since the magnetic encoder 12 can be read with high accuracy, highly reliable print quality can be obtained.

(Second Embodiment)
Next, a second embodiment of the conveyor belt will be described. The conveyance belt in the present embodiment is only different in that the high μ layer has a plurality of uneven patterns and the extending direction of the protrusions in each of the plurality of uneven patterns is different in the circumferential direction of the belt body. This is different from the first embodiment. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted or simplified.

FIG. 8 is a diagram illustrating a planar configuration when the transport belt 123 according to the present embodiment is developed. In FIG. 8, only the high μ layer 112 formed on the surface 50 a of the belt main body 50 is illustrated for easy understanding of the drawing.
The high μ layer 112 according to the present embodiment has a plurality of (two in the present embodiment) uneven patterns 170 as shown in FIG. 8. Specifically, the concavo-convex pattern 170 includes a first concavo-convex pattern 171 and a second concavo-convex pattern 172. The first concavo-convex pattern 171 and the second concavo-convex pattern 172 are different in the extending direction of the convex portions 171a and 172a in the circumferential direction of the belt main body 50 (X direction in FIG. 8).

  Specifically, the convex portion 171a constituting the first concave / convex pattern 171 is provided on the belt main body 50 so as to extend in the same direction as the convex portion 71 of the first embodiment. Further, the convex portion 172a constituting the second concave / convex pattern 172 is provided on the belt body 50 so as to extend in a direction orthogonal to the convex portion 171a.

  When the high μ layer 112 is manufactured, the uneven patterns 171 and 172 are configured by changing the direction of relative movement of the inkjet head 5 with respect to the belt body 50 along the circumferential direction of the belt body 50 as shown in FIG. Convex portions 171a and 172a (uneven patterns 171 and 172) to be formed can be formed.

  According to the present embodiment, since the high μ layer 112 has the first and second uneven patterns 171 and 172 in which the extending directions of the respective protrusions 171a and 172a are different, the protrusions generated in the conveyance direction of the recording paper P. The unevenness caused by 171 and 172 can be more dispersed as compared to the first embodiment.

The technical scope of the present invention is not limited to the above-described embodiment, and appropriate modifications can be made without departing from the spirit of the present invention.
In the above embodiment, the case where the convex portion 71 is formed by discharging the liquid material from the nozzle 5 a while moving the inkjet head 5 in the width direction of the belt main body 50 in conjunction with the rotation operation of the belt main body 50 has been described. However, as shown in FIG. 10, in a state where the rotation operation of the belt main body 50 is stopped, the inkjet head 5 itself is moved in a non-orthogonal direction (for example, 45 ° with respect to the width direction of the belt main body 50). The liquid material may be discharged from the nozzle while moving in the direction of forming the angle. Thus, the convex part 71 can be favorably formed along a predetermined direction by moving the inkjet head 5 in a state of being directly inclined with respect to the belt body 50. Moreover, when forming the convex part 71, since it is sufficient to drive only the inkjet head 5, the control can be simplified.

  In the above embodiment, the serial type inkjet head that discharges the liquid while moving in the width direction of the belt main body 50 has been described. However, the line type inkjet head 105 corresponding to the width of the belt main body 50 is used. In a state in which the rotation operation of the belt main body 50 is stopped, the inkjet head 105 is placed in a non-orthogonal direction with respect to the circumferential direction of the belt main body 50 as shown in FIG. The liquid material may be discharged from the nozzle 5a while moving in the direction in which the liquid is formed. Furthermore, as in the case shown in FIG. 9, the direction of movement of the inkjet head 105 relative to the belt body 50 may be changed to a direction that forms an angle of 155 ° with respect to the width direction of the belt body 50, for example. In this way, the convex portions 171a and 172a (the concave and convex patterns 171 and 172) constituting the concave and convex patterns 171 and 172 can be formed in a shorter time than in the second embodiment.

  Further, in the above embodiment, the case where the extending direction of the convex portion in the concave / convex pattern is not parallel to the circumferential direction of the belt main body 50 is taken as an example. May extend in parallel.

In the above-described embodiment, the example in which the suction hole 11 is formed using a mold has been described. However, the present invention is not limited to this, and a configuration using, for example, laser irradiation may be used.
In the above embodiment, the conveyor belt 23 is formed in a state of being stretched over the processing main driving roller 62 and the processing driven roller 63. However, the transporting roller 22, the platen 24, and the side plate used in the transporting unit 20 are used. 25 and the drive mechanism 26 may be assembled, and the belt body 50 may be passed over to manufacture the transport belt 23.
