  Hereinafter, embodiments of a drying apparatus and an image forming apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of an ink jet recording apparatus (ink jet printer 100) which is an embodiment of an image forming apparatus according to the present invention.

  As shown in FIG. 1, the ink jet printer 100 has a configuration in which a recording medium P that is an object to be conveyed is conveyed from one lower side of the recording apparatus main body 11 to the lower side of the other through the upper side and wound. The recording medium P is a sheet-like member and can be wound into a roll. In the present embodiment, the recording medium P may be any member that can be taken out from a roll shape, formed into a sheet shape, and conveyed in a specific direction. Examples of the recording medium P that can be used include paper (plain paper), coated paper, cardboard, OHP, plastic film, prepreg, and silver foil. In the description of the present embodiment, the case where the recording medium P is a sheet is taken as an example.

  In the inkjet printer 100, on one lower side of the recording apparatus main body 11, a roll body 2 in which a recording medium P is wound in a roll shape around a rotating shaft is held by a paper feed driving unit 1. The roll body 2 is drawn upward from the position of the paper feed drive unit 1, passes through the supply side guide plate 3, and is sandwiched between the transport roller 4 and the pinch roller 5 as the recording medium P. The transport roller 4 is a transport member that transports the recording medium P, and the pinch roller 5 is a clamping member that is disposed to face the transport roller 4 and sandwiches the recording medium P with the transport roller 4. The recording medium P is appropriately transported by a predetermined transport amount by the transport unit 50 including the transport roller 4 and the pinch roller 5.

  The recording medium P passes through the contact portion (nip) between the transport roller 4 and the pinch roller 5 and passes through the upper surface of the platen portion 7. When the recording medium P reaches the platen unit 7, an image is formed by ejecting ink onto the surface of the recording medium P while the liquid ejection head is scanned by scanning the carriage 6 disposed above the platen unit 7. . The liquid ejection head is a recording head that ejects liquid ink as droplets toward the recording medium P with predetermined timing and amount. The image forming unit 20 that includes the carriage 6 and forms an image on the recording medium P is configured by discharging liquid ink at a predetermined timing by the liquid discharge head.

  Thereafter, the recording medium P on which the image is formed passes through the winding-side guide plate 8 and is wound around the paper tube 10 held by the winding drive unit 9 on the other lower side of the recording apparatus main body 11. The recording medium P on which the image is formed is appropriately cut according to a preset size by a cutting device 12 disposed near the lower end of the winding side guide plate 8 as necessary.

  The place where the cutting device 12 is installed is not limited to this, and can be arbitrarily changed. Further, here, the recording medium P after the image is formed is exemplified as the object to be cut, but if the sheet member can be cut by a blade unit included in the cutting device 12 described later, the inkjet printer 100 is used. Applicable to.

  The scanning operation of the carriage 6 and the movement of the cutting device 12, the motor for driving the conveying roller 4, the motor used for the paper feed driving unit 1, the driving of the motor used for the winding driving unit 9, etc. 11 is controlled by a control device 13 included in the control unit 11.

  In the inkjet printer 100, the paper feed drive unit 1, the transport roller 4, the pinch roller 5, and the take-up drive unit 9 cooperate with the control device 13 to provide a transport mechanism that transports the roll body 2 along the transport path. Constitute.

  Further, in the ink jet printer 100, the conveyance path is formed by the supply side guide plate 3, the platen unit 7, and the winding side guide plate 8.

  In addition, the inkjet printer 100 is provided with a drying device 14 at the position of the take-up guide plate 8 for quickly drying the ink of the recording medium P on which an image is formed and maintaining the image quality. The drying device 14 is a device that includes a heating unit that heats both sides of the recording medium P to be conveyed (an upper surface on which ink is attached and a rear surface on the opposite side). Details of the drying device 14 will be described later.

  The configuration including the cutting device 12, the drying device 14, and the control device 13 may be referred to as a recording medium cutting system. Moreover, when it does not ask | require a conveyed product, you may call a conveyed product cutting system.

  By the way, if the object to be transported is other than the recording medium P and is regarded as an object to be coated having a property to which the liquid can be applied and adhered, various forms can be applied, for example, the liquid adheres at least temporarily. Anything is possible. Moreover, the thing which a liquid adheres and adheres, the thing which adheres and osmose | permeates, etc. are contained. Unless specifically limited, all materials that can be formed into a roll with a liquid attached are included. In addition, it is a precondition that the liquid needs to be charged and transferred by ions in the liquid when a voltage is applied. Further, any material may be used as long as it has a viscosity and surface tension that can be applied to the above materials, and is not particularly limited, but a material having a viscosity of 30 mPa · s or less at room temperature and normal pressure or by heating and cooling is preferable.

  Examples of liquids that can be applied to the ink jet printer 100 include solvents such as water and organic solvents, colorants such as dyes and pigments, functional materials such as polymerizable compounds, resins, and surfactants, DNA, amino acids and proteins, Examples include solutions, suspensions, emulsions and the like containing biocompatible materials such as calcium and edible materials such as natural pigments. General-purpose examples of ink are water-based ink, UV ink, non-VOC ink, vegetable oil ink, soybean oil ink, glycol ink, non-toluene ink, EB ink and other printing ink, pigment ink, dye ink, indelible ink, metal ink, invisible Examples thereof include ink and fluorescent ink. In addition, it is also possible to apply recently developed low odor ink jet inks, UV curable precoat liquids, and the like. These can be used for applications such as ink for inkjet, surface treatment liquid, components for electronic elements and light emitting elements, liquid for forming electronic circuit resist patterns, and material liquid for three-dimensional modeling.

  Returning to the description of the configuration and operation of the inkjet printer 100, with reference to FIG. In the above-described ink jet printer 100, when the recording medium P after the image is formed enters the cutting device 12, the recording medium P is adjusted by adjusting the degree of heating of the recording medium P by the heating means provided in the drying device 14. The amount of winding at the tip of can be changed. Specifically, a temperature difference is given to the front surface and the back surface of the recording medium P by making a difference between the heating degree on one side of the recording medium P and the heating degree on the other side. Due to this temperature difference, the curvature of the tip of the recording medium P changes. Utilizing such properties of the recording medium P, the drying device 14 described below is disposed downstream of the drying device 14 by controlling the position of the leading end of the conveyed recording medium P. The conveyance failure to the cutting device 12 is prevented.

  Next, the overall structure of the drying device 14 will be schematically described. FIG. 2 is a schematic perspective view for explaining the drying device 14 included in the inkjet printer 100. As shown in FIG. 2, the drying device 14 is arranged on the upstream side of the cutting device 12 and can apply heat from both the front surface (image forming surface) and the back surface of the recording medium P being conveyed. Means.

  In the drying device 14, the recording medium P after the image is formed is conveyed along the winding-side guide plate 8 in the direction of the arrow. A cutter mechanism 12a constituting a cutting mechanism included in the cutting device 12 and a cutter guide mechanism 12b for guiding the movement of the cutter mechanism 12a are arranged on the downstream side of the winding side guide plate 8. The cutter mechanism 12a cuts the recording medium P at a predetermined position by moving so as to cross the width direction of the recording medium P in a direction orthogonal to the conveyance direction of the recording medium P. The cutter guide mechanism 12b is a member for moving the cutter mechanism 12a in a direction orthogonal to the conveyance direction of the recording medium P. The cutter guide mechanism 12b is composed of a long member longer than the width dimension of the recording medium P.

  Here, the cutter mechanism 12a and the cutter guide mechanism 12b will be described in detail. FIG. 3 is a plan view of the cutting device 12 as viewed from the direction in which the recording medium P enters. As shown in FIG. 3, the cutter mechanism 12 a includes an upper blade unit 121 and a lower blade unit 122. Individual cutters are fixed to the upper blade unit 121 and the lower blade unit 122, respectively. In addition, an opening is formed between the upper blade unit 121 and the lower blade unit 122 so that the end in the width direction of the recording medium P is guided to both blades.

  The cutter guide mechanism 12b moves both blades fixed to the cutter mechanism 12a from one end side in the width direction of the recording medium P to the other end side. During this movement, the two blades sandwich the recording medium P and cut it. After cutting the recording medium P, the cutter mechanism 12a is returned to the home position by the cutter guide mechanism 12b until the recording medium P is next conveyed.

  In particular, the recording medium P that is conveyed has its one end in the width direction passing through the opening of the cutter mechanism 12a, so that when the cutter mechanism 12a is moved later, the recording medium P is moved. Is guided by both blades. Therefore, unless the leading end of the recording medium P is conveyed at a position passing through the opening of the cutter mechanism 12a, the leading end of the recording medium P collides with the cutter mechanism 12a or the cutter guide mechanism 12b and stays there. It becomes a conveyance abnormality. In order to prevent this, control for adjusting the position of the leading end of the recording medium P is performed by adjusting the temperature of the drying device 14.

  FIG. 4 is a longitudinal sectional view of the drying device 14 according to the present embodiment. As shown in FIG. 4, the drying device 14 is arranged so as to sandwich the winding-side guide plate 8 and includes an upper heater 141 and a lower heater 142.

  The upper heater 141 is a first heating unit arranged at a predetermined interval in the transport direction, and includes a plurality of upper heaters 141a, 141b, 141c, and 141d. In addition, the heating means which comprises the upper heater 141 is not limited to four pieces, You may arrange | position more in a conveyance direction. The upper heater 141 heats the surface (surface on which an image is formed) of the recording medium P, and promotes drying of the attached ink.

  Further, a lower heater 142 as a second heating means is disposed on the winding side guide plate 8. Since the lower heater 142 heats the recording medium P from the winding-side guide plate 8 side, it serves as a heating means for overheating the back surface (the surface on which no image is formed) of the recording medium P.

  The heating operation by the upper heater 141 and the lower heater 142 is controlled by the control device 13 provided in the recording apparatus main body 11. Therefore, the drying device 14 is a device that can adjust the degree of heating of the recording medium P under the control of the control device 13 and can adjust the temperature difference between the front surface and the back surface of the recording medium P.

  When the temperature difference between the front surface and the back surface of the recording medium P is controlled by adjusting the temperatures of the upper heater 141 and the lower heater 142, the curvature of the recording medium P changes according to the temperature difference. That is, the position of the leading end in the conveyance direction of the recording medium P changes depending on the temperature difference between the front surface and the back surface of the recording medium P. Therefore, the position of the leading end of the recording medium P can be controlled by the temperature difference generated in the recording medium P in the drying device 14.

  As already described, if the leading end of the recording medium P does not pass through the opening of the cutter mechanism 12a included in the cutting device 12, then the cutting operation by the cutter mechanism 12a (the recording medium P is sandwiched in a direction orthogonal to the transport direction). In such a movement operation, the recording medium P is not properly cut.

  Therefore, in order to control the position of the leading end of the recording medium P, it is necessary to create an optimal temperature difference depending on the material and type of the recording medium P. Therefore, the control device 13 according to the present embodiment stores in advance control data for forming a temperature difference such that the curvature of the recording medium P becomes an optimum value for each type of the recording medium P. This control data is stored in an upper part so that the position of the leading end of the recording medium P conveyed to the cutting device 12 is the optimum position even if the type of the recording medium P is different. This is data for setting the temperatures of the heater 141 and the lower heater 142. For example, when a polyvinyl chloride film is used as the recording medium P, the optimum temperature difference is set to 10 ° C. or less. In this case, in the control data, when the recording medium P is “polyvinyl chloride film”, the temperature of the upper heater 141 and the lower heater 142 is set so that the temperature difference generated on both surfaces of the recording medium P is within 10 ° C. Data to control each is included.

  More specifically, the above control data creates recording medium type data reflecting the type (material, material, etc.) of the recording medium P, and a temperature difference for controlling the position of the leading end corresponding to this. Therefore, it has a data structure in which the temperature setting value of the upper heater 141 and the temperature setting value of the lower heater 142 are associated with each other. In addition, as a method of giving the control device 13 the type of the recording medium P to be transported by the ink jet printer 100, a user interface provided in the ink jet printer 100 may be used. That is, it is only necessary that the user can set the type of the recording medium P that is dried in the drying device 14 and the position of the leading end is controlled.

  Here, the functional configuration of the control device 13 will be described with reference to FIG. As shown in FIG. 5, the control device 13 according to the present embodiment includes a first temperature control unit 131 that controls the temperature of the upper heater 141, a second temperature control unit 132 that controls the temperature of the lower heater 142, A storage unit 133 that stores control data used for temperature control in each of the one temperature control unit 131 and the second temperature control unit 132, and a medium setting unit 134 that sets the type of the recording medium P are provided.

  The control data stored in the storage unit 133 has a data structure distinguished according to the type of the recording medium P as described above. The medium setting unit 134 is a functional block configured by a user interface of the inkjet printer 100 or the like. The first temperature control unit 131 and the second temperature control unit 132 acquire the type of the recording medium P set in the medium setting unit 134, acquire control data based on the acquired type from the storage unit 133, and each heating unit Execute the temperature control.

  The control device 13 having the above configuration specifies temperature setting values of the upper heater 141 and the lower heater 142 according to the type of the recording medium P set by the user, and the upper heater 141 and the lower heater included in the drying device 14. Each of 142 is controlled to become the set temperature.

  The upper heater 141 and the lower heater 142 are preferably infrared heaters. In this case, the heating to the recording medium P is due to radiant heat. By using the radiant heat to heat the surface of the recording medium P in a non-contact manner, the influence of the recording medium P on the image formation can be eliminated.

  In the heating by radiant heat, the upper heater 141 and the lower heater 142 are not set to the set temperature immediately after the operation of the ink jet printer 100 is started, and the degree to which the front and back surfaces of the recording medium P are set is set. It takes time. Therefore, the control by the control device 13 may be performed first so that the drying device 14 starts the heating operation before the image forming and conveying operations of the inkjet printer 100 are started.

  Specifically, the control device 13 also takes into account the temperature fluctuation time until the temperature difference between the two surfaces of the recording medium P during heating reaches a state where the leading end portion of the recording medium P is controlled to an optimum position. The start timing of the heating operation of the upper heater 141 and the lower heater 142 and the degree of heating may be controlled.

  As described above, according to the present embodiment, the recording medium P can always pass through the openings of the upper blade unit 121 and the lower blade unit 122 of the cutter mechanism 12a. That is, using the drying device 14 necessary for drying the recording medium P after image formation in the ink jet printer 100, the recording medium P after image formation is dried, and the recording medium P is clogged due to poor conveyance. It can be prevented at low cost. If the transported object is not the recording medium P but another sheet member, the operation of the drying device 14 is controlled so as to create an appropriate temperature difference corresponding to the member, thereby preventing clogging due to transport failure. be able to.
