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

As shown in FIG. 1, the inkjet printer 100 includes a configuration in which a recording medium P, which is an object to be transported, is conveyed and wound from one lower side of the recording apparatus main body 11 to the lower side of the other via the upper side. The recording medium P is a sheet-like member and can be rolled into a roll. In the present embodiment, the recording medium P may be any member as long as it can be taken out from the 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, thick paper, OHP, plastic film, prepreg, silver leaf, and the like. The description of the present embodiment will take the case where the recording medium P is paper as an example.

In the inkjet printer 100, a roll body 2 in which a recording medium P is wound in a roll shape on a rotating shaft is held in a paper feed driving unit 1 on the lower side of one side of the recording device main body 11. The roll body 2 is pulled upward from the position of the paper feed driving 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 transfer roller 4 is a transfer member that conveys the recording medium P, and the pinch roller 5 is a holding member that is arranged to face the transfer roller 4 and sandwiches the recording medium P with the transfer roller 4. The recording medium P is appropriately transported in 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 approaches the platen portion 7, an image is formed by ejecting ink to the surface of the recording medium P while scanning the liquid ejection head by scanning the carriage 6 arranged above the platen portion 7. .. The liquid ejection head is a recording head that ejects liquid ink as droplets toward the recording medium P at a predetermined timing and amount. An image forming unit 20 that forms an image on the recording medium P is configured by ejecting the liquid ink at a predetermined timing by the liquid ejection head including the carriage 6.

The recording medium P on which the image is formed passes through the take-up side guide plate 8 and is taken up by the paper tube 10 held by the take-up drive unit 9 on the other lower side of the recording device main body 11. The recording medium P on which the image is formed is appropriately cut to a preset size by the cutting device 12 arranged near the lower end of the take-up side guide plate 8 as needed.

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

The operation of scanning the carriage 6 and moving the cutting device 12, the motor for driving the transport roller 4, the motor used for the paper feed drive unit 1, the drive of the motor used for the take-up drive unit 9, and the like are the recording device main body. It is controlled by the control device 13 provided in 11.

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

Further, in the inkjet printer 100, the transport path is formed by the supply side guide plate 3, the platen portion 7, and the take-up side guide plate 8.

Further, in the inkjet printer 100, a drying device 14 for quickly drying the ink of the recording medium P on which the image is formed to maintain the image quality is arranged at the position of the winding side guide plate 8. The drying device 14 is a device provided with heating means for heating both both sides (the upper surface on which ink is attached and the back surface on the opposite side) of the recorded medium P to be conveyed. 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. Further, when the transported object is not limited, it may be called a transported object 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 of being coated with a liquid and having a property of being adhereable, various forms can be applied, for example, the liquid is adhered at least temporarily. Anything that is possible will do. In addition, those to which liquid adheres and sticks, those to which liquid adheres and permeates, and the like are also included. Unless otherwise specified, all materials to which a liquid adheres and can be formed into a roll are included. Further, it is a premise that the liquid needs to be charged and transferred by the ions in the liquid when a voltage is applied. Further, the material may have a viscosity and surface tension that can be applied to the above material, and is not particularly limited, but a material having a viscosity of 30 mPa · s or less at normal temperature / pressure or by heating / cooling is preferable.

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

With reference to FIG. 1, the description of the configuration and operation of the inkjet printer 100 will be returned. In the inkjet printer 100 described above, when the recording medium P after the image is formed enters the cutting device 12, the recording medium P is heated by adjusting the degree of heating to the recording medium P by the heating means provided in the drying device 14. The amount of winding at the tip of the can be changed. Specifically, a difference is made between the degree of heating on one side of the recording medium P and the degree of heating on the other side to give a temperature difference between the front surface and the back surface of the recording medium P. Due to this temperature difference, the curvature of the tip of the recording medium P changes. Utilizing such a property of the recording medium P, in the drying device 14 described below, the drying device 14 is arranged downstream of the drying device 14 by controlling the position of the tip end portion of the conveyed recording medium P. Prevents poor transport to the cutting device 12.

Next, the overall structure of the drying device 14 will be schematically described. FIG. 2 is a schematic perspective view for explaining a 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 is heated so that heat can be applied from both the front surface (image forming surface) and the back surface of the conveyed recording medium P. It has the means.

In the drying device 14, the recording medium P after the image is formed is conveyed along the take-up side guide plate 8 in the direction of the arrow. On the downstream side of the take-up side guide plate 8, 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. 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 transport 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 transport 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 approach direction of the recording medium P. As shown in FIG. 3, the cutter mechanism 12a has 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. Further, an opening is formed between the upper blade unit 121 and the lower blade unit 122 so that the widthwise end portion 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 double-edged 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 next recording medium P is conveyed.

The conveyed recording medium P is configured such that one end thereof in the width direction passes through the opening of the cutter mechanism 12a, whereby the recording medium P is moved when the cutter mechanism 12a is moved later. Is guided by the double-edged blade. Therefore, if the tip of the recording medium P is not conveyed at a position passing through the opening portion of the cutter mechanism 12a, the tip of the recording medium P will collide with the cutter mechanism 12a or the cutter guide mechanism 12b and stay there. , The transport becomes abnormal. In order to prevent this, control for adjusting the position of the tip portion of the recording medium P is performed by adjusting the temperature of the drying device 14.

FIG. 4 is a vertical 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 take-up side guide plate 8, and includes an upper heater 141 and a lower heater 142.

The upper heater 141 is a first heating means arranged at predetermined intervals in the transport direction, and is composed of a plurality of upper side heaters 141a, 141b, 141c, 141d. The number of heating means constituting the upper heater 141 is not limited to four, and more may be arranged in the transport direction. The upper heater 141 heats the surface of the recording medium P (the surface on which the image is formed) to accelerate the drying of the adhered ink.

Further, a lower heater 142 as a second heating means is arranged on the take-up side guide plate 8. Since the lower heater 142 heats the recording medium P from the winding side guide plate 8, the lower heater 142 serves as a heating means for overheating the back surface (the surface on which the image is not 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 included in the recording device main body 11. Therefore, the drying device 14 is a device capable of adjusting the degree of heating to the recording medium P by the control of the control device 13 and adjusting 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 tip portion of the recording medium P in the transport direction changes depending on the temperature difference between the front surface and the back surface of the recording medium P. Therefore, the position of the tip portion of the recording medium P can be controlled by the temperature difference generated in the recording medium P in the drying device 14.

As described above, if the tip of the recording medium P does not pass through the opening of the cutter mechanism 12a provided in the cutting device 12, then the cutting operation by the cutter mechanism 12a (the recording medium P is sandwiched in the direction orthogonal to the transport direction). In the operation of moving like this), the recording medium P is not cut correctly.

Therefore, in order to control the position of the tip of the recording medium P, it is necessary to create an optimum 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 so 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 the upper part so that the position of the tip 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 a "polyvinyl chloride film", the temperatures of the upper heater 141 and the lower heater 142 are included so that the temperature difference generated on both sides of the recording medium P is within 10 ° C. Each contains data to control.

More specifically, the above control data creates a recording medium type data that reflects the type (material, material, etc.) of the recording medium P, and a temperature difference that controls the position of the tip portion to the optimum position correspondingly. It has a data structure in which the temperature set value of the upper heater 141 and the temperature set value of the lower heater 142 are associated with each other. As a method of giving the type of the recording medium P to be conveyed by the inkjet printer 100 to the control device 13, it is sufficient that the user interface provided in the inkjet printer 100 can be used. That is, the type of the recording medium P that is dried in the drying device 14 and whose position of the tip portion is controlled may be set by the user.

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, and a second. It includes a storage unit 133 for storing control data used for temperature control in each of the temperature control unit 131 and the second temperature control unit 132, and a medium setting unit 134 for setting the type of the recording medium P.

As described above, the control data stored in the storage unit 133 has a data structure distinguished by the type of the recording medium P. The medium setting unit 134 is a functional block configured by a user interface or the like of the inkjet printer 100. 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 the control data based on the acquired type from the storage unit 133, and each heating means. Perform temperature control.

The control device 13 having the above configuration specifies the temperature set 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 are specified. Each of the 142 is controlled to reach the set temperature.

It is preferable to use an infrared heater for both the upper heater 141 and the lower heater 142. In this case, the heating to the recording medium P is due to radiant heat. By heating the surface of the recording medium P in a non-contact manner using radiant heat, the influence of the contact of the recording medium P on the image formation can be eliminated.

In addition, in the heating by radiant heat, the upper heater 141 and the lower heater 142 do not reach the set temperature immediately after the operation of the inkjet printer 100 starts, and the front surface and the back surface of the recording medium P do not reach the set temperature. It takes time. Therefore, the control device 13 may first control the drying device 14 so that the drying device 14 starts the heating operation before the image forming and transporting operation of the inkjet printer 100 starts.

Specifically, the control device 13 also considers the temperature fluctuation time until the temperature difference between both sides of the recording medium P during heating is in a state of controlling the tip portion of the recording medium P to the optimum position. The start timing of the heating operation of the upper heater 141 and the lower heater 142 and the heating degree 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, the inkjet printer 100 uses the drying device 14 required to dry the recording medium P after image formation, and while drying the recording medium P after image formation, clogging due to poor transport of the recording medium P is caused. It can be prevented at low cost. If the object to be transported is not the recording medium P but another sheet member, if the operation of the drying device 14 is controlled so as to create an appropriate temperature difference corresponding to the member, clogging due to poor transportation can be prevented. be able to.
