Description

  The present invention relates to an ink jet recording apparatus and a recording method thereof.

  2. Description of the Related Art Conventionally, an ink jet recording apparatus that performs recording on a recording medium by ejecting ink droplets from nozzles provided in a recording head is known. Among such ink jet recording apparatuses, there is one in which a recording medium is held on a flat platen and a recording head is mounted on a carriage that moves along the platen. The carriage is reciprocated on the recording medium. Then, recording is performed by ejecting ink droplets from a nozzle of the mounted recording head onto a recording medium. In such an ink jet recording apparatus, a suction hole is provided in the platen, and the recording medium is sucked and fixed to the platen through the suction hole. Therefore, the recording surface of the recording medium can be kept flat along the platen.

  The recording medium is slid on the platen and conveyed by the conveying device while being sucked by the suction holes. In such a recording operation of the ink jet recording apparatus, the recording medium is transported by a predetermined movement distance and stopped, and ink is ejected from the nozzles onto the recording medium while scanning the carriage in the width direction of the recording medium. Record. When one scan is completed, the recording medium is again conveyed by a predetermined distance and stopped. Then, recording is performed by discharging ink in the same manner as described above. By repeating such an operation, a desired image is formed on the recording medium.

  The recording medium needs to slide on the platen. However, the recording medium may not be smoothly moved on the platen due to the frictional resistance between the platen and the recording medium or due to the suction force to the recording medium by the suction holes, and may be conveyed in a distorted state such as a wavy state. The For example, as disclosed in Patent Document 1, an inkjet recording apparatus is disclosed in which a frictional resistance between the platen and the recording medium is reduced by taking measures such as providing a fluororesin layer on the surface of the platen. Yes. Also, in Patent Document 1, an ink jet recording apparatus is disclosed in which a groove is provided in the platen to reduce the frictional resistance between the platen and the recording medium, and the contact area between the platen and the recording medium is reduced.

JP 2004-122554 A

  However, the inkjet recording apparatus uses a PVC tarpaulin or cloth as a recording medium, or a resin sheet made of various resins such as polyester and PVC. Various recording media have different frictional resistances with respect to the platen. Further, the recording medium is easily bent depending on the thickness and material. Further, when the platen is provided with a groove, the temperature of the part corresponding to the groove of the recording medium becomes lower than the other part in the case of a platen with a heater that promotes drying of the ink. For this reason, there is a difference in the drying speed of the ink, and a groove pattern may appear in the formed image. Further, with a conventional platen, depending on the type of the recording medium, there may be a case where the recording medium undulates due to frictional resistance and cannot perform proper recording. Further, depending on the type of the recording medium, the ink may bend along the groove of the platen and the desired ink cannot be ejected to a desired position, so that proper recording may not be performed.

Further, another recording method of the present invention for solving the above-mentioned problems is a recording apparatus that conveys a recording medium, a recording head that includes a plurality of nozzles for ejecting ink, and a surface that faces the recording medium. there a flat platen, the communication with the suction means for sucking the recording medium and a suction hole, a recording method for an ink jet recording apparatus for conveying while adsorbing the recording medium to said platen to said platen, said The ink jet recording apparatus further includes input means, storage means for storing type information of the platen cover placed on the platen corresponding to the type of the recording medium to be conveyed, and at least when arranged on the platen. has a flat platen cover having a communication hole for exposing one of said suction holes, and distribution of the platen cover over said platen A step of a step of conveying the recording medium while operating the suction means, said suction means is operated, have a, a step of discharging the ink onto the recording medium held on the platen cover The step of disposing the platen cover on the platen includes the step of inputting the type of the recording medium used in the ink jet recording apparatus from the input unit, and the type of the input recording medium based on the type of the input recording medium.

A recording medium 17 is sandwiched between the transport roller 9 and the pressure roller unit 8 and is transported by the rotation of these rollers. Further, a platen 12 that supports the recording medium 17 is provided at a location adjacent to the transport device 10. A platen cover 20 is placed and fixed on the platen 12. The platen 12 and the platen cover 20 serve as locations for printing and recording on the recording medium 17 by the printing recording apparatus 2. A heater for heating the platen 12 is provided under the platen 12. With this heater, the platen 12 and the platen cover 20 are heated, and the recording medium 17 is further heated to promote fixing of the ink ejected to the recording medium 17. The platen 12 is provided on the base 13 so as to extend in a direction orthogonal to the direction in which the recording medium 17 is conveyed. Further, 19 pairs of the transport roller 9 and the pressure roller unit 8 are arranged on the same axis line at adjacent portions of the platen 12 at a predetermined interval, for example, 87.65 mm.

  The printing recording apparatus 2 roughly includes an inkjet head 3 that performs recording by ejecting ink droplets onto a recording medium 17, a carriage 4 that houses the inkjet head 3, a transport belt 11 that is connected to the carriage 4, A driving pulley 5 and a driven pulley 6 that move the conveying belt 11, a driving motor 18 that rotationally drives the driving pulley 5, and a guide rail 7 that guides the scanning of the carriage 4 in a direction orthogonal to the conveying direction of the recording medium 17. It has. Further, like the platen 12, the transport belt 11 and the guide rail 7 are provided on the base 13 so as to extend in a direction orthogonal to the direction in which the recording medium 17 is transported. The carriage 4 slides in a direction orthogonal to the direction in which the recording medium 17 is conveyed, that is, in the direction of the bidirectional arrow AB in the drawing.

  Ink supplied to the inkjet head 3 is stored in the ink cartridge 14. The ink cartridge 14 is a replaceable cartridge type ink container. Replace when ink runs out.

  The pressure roller unit 8 is disposed so as to form a pair for each conveyance roller 9 that conveys the recording medium 17. The roller of the pressure roller unit 8 is driven to rotate while pressing the recording medium 17 toward the conveying roller 9. That is, the lower surface of the recording medium 17 is in contact with the conveying roller 9, and the upper surface is in contact with the roller of the pressure roller unit 8. The pressure roller unit 8 is fixedly attached to the base 13 of the printer 1.

  The ink jet recording apparatus 1 includes suction means for adsorbing the recording medium 17 to the platen cover 20 or the platen 12. The suction means is roughly provided in the platen cover 20 and a suction hole that penetrates the platen 12, a suction fan 16 that sucks air, a suction chamber 15 that connects the suction hole and the suction fan 16, and the platen cover 20. The communication hole 19 is provided. The platen 12 has a plurality of suction holes communicating with the suction chamber 15. A suction hole opening is formed on the surface of the platen 12. The suction chamber 15 is partitioned into four rooms, and a suction fan 16 is provided for each room. The communication hole 19 of the platen cover 20 passes through the platen cover 20. Details will be described later.

  FIG. 2 is a cross-sectional view schematically showing a schematic configuration of a platen of an ink jet recording apparatus according to a preferred embodiment of the present invention.

  The inkjet head 3 ejects ink from the nozzles provided on the nozzle surface 22 while scanning the recording medium 17. Ink is ejected from nozzles within the recording range 21, which is a range in which nozzles capable of ejecting ink are disposed. The ink ejection timing of the designated nozzle is designated by a control means (not shown), and the nozzle is further driven to eject ink and perform recording. A platen cover 20 is placed on the platen 12. The platen cover 20 has a plurality of communication holes 19 formed in a flat plate. The platen 12 is provided with a plurality of suction holes 23. A suction chamber 15 is provided below the platen 12. The suction chamber 15 communicates with the communication hole 19 through the suction hole 23. The suction chamber 15 is provided with a suction fan 16 and discharges air from the suction chamber 15 to the outside. A heater 24 is provided on the back surface of the platen 12. The heater 24 heats the platen 12.

  Both ends of the platen cover 20 in the conveyance direction of the recording medium 17 are bent. The strength of the platen cover 20 is improved by bending. When the platen cover 20 is handled at the time of replacement or the like, it is necessary to have a strength that facilitates handling. In addition, the direction when the platen 12 is placed on the platen 12 can be determined by bending both ends at different angles.

  The first bent portion 25 bends the end portion of the platen cover 20 by 90 degrees. The first bent portion 25 is in contact with the edge 27 of the first concave portion 26 provided in the platen 12. The edge 27 is provided linearly in the longitudinal direction of the platen 12. By fixing the platen cover 20 by bringing the first bent portion 25 into contact with the edge 27, the platen 12 and the platen cover 20 can be positioned with respect to the conveyance direction of the recording medium 17. The first recess 26 also serves as a guide rail for a paper presser described later.

  The second bent portion 28 bends the end portion of the platen cover 20 by 45 degrees. The second bent portion 28 is inserted into a second recess 29 provided in the platen 12. The second bent portion 28 is provided linearly in the longitudinal direction of the platen 12. The second recess 29 is also used as a guide rail for a paper presser described later.

  The platen cover 20 is fixed to the platen 12 with screws 30. The recording medium 17 is conveyed while being raised along the screw 30 at the portion of the screw 30, but by arranging at least one suction hole, preferably two or more, between the screw 30 and the recording range 21, The recording medium 17 is attracted to the platen cover 20 so that the recording range 21 is kept flat.

  The platen cover 20 should be as thin as possible in order to efficiently transfer the heat of the platen 12 heated by the heater 24 to the recording medium 17. However, if it is too thin, the strength to keep it flat will be insufficient. A material having a low thermal resistance is preferable, and aluminum or an aluminum alloy is preferable. If such a material is used, it is possible to coat or paint the surface containing a fluororesin. The platen cover 20 is preferably a 0.5 mm plus or minus 0.2 mm plate in consideration of strength and thermal resistance.

  One communication hole 19 is preferably opened so that at least one suction hole 23 is exposed, more preferably a plurality of, more preferably 10 or more suction holes 23 are exposed. If the opening of the communication hole 19 is too small, the area for sucking the recording medium 17 becomes small, and the adsorption becomes insufficient. On the other hand, if the size is too large, the recording medium 17 is depressed by suction, and the image quality is affected. However, in order to reduce the frictional resistance between the platen cover 20 and the recording medium 17, it is preferable that the opening of the communication hole 19 is large. It is preferable to prepare a plurality of appropriate ratios of the opening portion and the closing portion of the platen cover 20 according to the type of the recording medium 17 and replace them according to the type of the recording medium 17.

  The material of the platen cover 20 is preferably metal, but may be plastic. In this case, a difference in thermal expansion coefficient from the platen 12 occurs, so that the fixing means does not distort when there is a difference in thermal expansion.

  The surface of the platen cover 20 is preferably painted with a fluororesin in order to reduce the frictional resistance with the recording medium 17. Also, the frictional resistance may be reduced by burring or drawing the communication hole 19 and providing a convex portion at the opening.

  The platen cover 20 is made of an optimum material for the recording medium, optimized for the communication hole pitch, optimized for the diameter of the opening of the communication holes, surface treatment such as coating, etc. It is desirable to prepare a product with By doing so, it can be exchanged according to the type of the recording medium 17, and printing can be performed by the more preferable platen cover 20. Thereby, the print quality is improved.

  FIG. 3 is a diagram schematically showing a schematic configuration of the platen of the ink jet recording apparatus according to the preferred embodiment of the present invention.

  There are many suction holes 23 on the surface of the platen 12. The suction hole 23 penetrates from the front surface to the back surface of the platen 12. The surface of the platen 12 is preferably coated with a fluororesin or the like in order to reduce the frictional resistance with the recording medium 17. Further, the surface of the platen 12 can be provided with extremely minute irregularities by painting or coating. The irregularities are minute irregularities that do not affect the recording surface of the recording medium 17. For this reason, a minute space exists over the entire surface between the platen 12 and the platen cover 20. Therefore, the suction hole 23 arranged on the surface of the platen 12 is not completely blocked by the platen cover 20, and the suction capability is reduced but the suction function is maintained. Therefore, although the suction capability of the suction hole 23 of the platen 12 other than the part of the communication hole 19 of the platen cover 20 is lowered, the suction hole 23 can be sucked over the whole. When adsorbing the recording medium 17, the suction holes 23 of the platen 12 can be transported stably without being stopped unnecessarily.

  As another form, the platen cover 20 may be brought into surface contact with the surface of the platen 12 without unevenness. In this case, in a place where the communication hole 19 of the platen cover 20 is not provided, the suction hole 23 formed on the surface of the platen 12 is closed, and the suction function is realized only by the exposed suction hole 23. In this case, the recording medium 17 is sucked by the suction holes 23 corresponding to the communication holes 19 of the platen cover 20. The communication hole 19 is formed in 75% or more of the surface of the platen cover 20. Since the main part of the recording medium 17 is sucked by the communication hole 19, there is no problem in suction and conveyance.

  The suction chamber 15 below the platen 12 is divided into four chambers, each having a suction fan 16. The platen cover 20 is divided into two by a dividing portion 31. The dividing unit 31 is linearly divided in a direction intersecting the conveyance direction of the recording medium 17 and is in contact with each other. Further, a gap is formed at the end portion 32 of the dividing portion 31 so that the platen covers 20 do not contact each other. The gap is provided to prevent the first bent portion 25 or the second bent portion 28 of the platen cover 20 from overlapping each other. Further, the bent portions 25 and 28 of the platen cover 20 and a paper presser described later also serve as the concave portions 26 and 29 in order to realize respective functions. Therefore, in order not to interfere with each other, a notch 33 is provided at the end of the platen cover 20 in the longitudinal direction so that the bent portions 25 and 28 and a paper presser described later do not hit the recesses 26 and 29. ing. The platen cover 20 may be divided into three or more in addition to dividing into two. Moreover, you may comprise by one, without dividing | segmenting. When one platen cover 20 is configured, it is necessary to make the platen cover 20 thicker than the multi-divided one so as not to have insufficient strength. Further, the platen cover 20 may have a necessary width according to the width of the recording medium 17.

  FIG. 4 is an enlarged cross-sectional view of the platen portion of the ink jet recording apparatus according to the preferred embodiment of the present invention. The communication hole 19 communicates with the back surface of the platen 12 through a plurality of suction holes 23. Further, the number of suction holes 23 for one communication hole 19 is configured so as to balance suction.

  FIG. 5 is an enlarged view showing a platen and a fixing portion of the platen cover of the ink jet recording apparatus according to the preferred embodiment of the present invention. The screw head portion of the screw 30 is formed of a curved surface so that the front end and the back surface are not caught when the recording medium 17 is set or conveyed, and the recording medium 17 is smoothly conveyed. In addition, the second bent portion 28 is bent at an angle of about 45 degrees. By making the bending angle an obtuse angle, the front and back surfaces are not caught when the recording medium 17 is set or conveyed. This is because the recording medium 17 is smoothly conveyed.

  FIG. 6 is a view showing a paper pressing portion of the ink jet recording apparatus according to the preferred embodiment of the present invention. A paper presser 34 is fixed with the first recess 26 and the second recess 29 provided on the platen 12 as guide rails. The paper presser 34 is a restricting portion that restricts lifting of the end of the recording medium 17. By passing the recording medium 17 under the presser 35, the lifting is prevented. The paper presser 34 has no holes and blocks the communication holes 19 to prevent suction leakage.

  Next, the operation of the ink jet recording apparatus 1 will be described. There are a plurality of types of platen covers 20 depending on the type of the recording medium 17. The optimum platen cover 20 is selected according to the type of the recording medium 17 to be used.

  The platen cover 20 is placed on the platen 12 of the ink jet recording apparatus 1, and the platen cover 20 is fixed to the platen 12 by fixing means such as screws 30. Thereafter, the transport device 10 is operated while operating the suction fan 16 to transport the recording medium 17. When the recording medium 17 is set in the inkjet recording apparatus 1, the paper presser 34 is fitted into the first concave portion 26 and the second concave portion 29 of the platen 12, and both ends of the recording medium 17 are pressed by the presser portions 35. The recording medium 17 slides on the surface of the platen cover 20 while being attracted to the platen cover 20. The recording medium 17 stops after being conveyed by a predetermined distance, and the print recording apparatus 2 is operated to print a desired image on the recording medium 17. During this printing, the suction fan 16 is operated to attract the recording medium 17 to the platen cover 20. When one printing scan is completed, the recording medium 17 is conveyed again by a predetermined distance, that is, a predetermined printing width, and printing is performed by the printing recording apparatus 2. Control of conveyance and printing are controlled by a control means (not shown).

  FIG. 7 is a view showing a first modification of the platen cover fixing means of the ink jet recording apparatus according to the preferred embodiment of the present invention.

  The platen 12 is provided with a thread groove 40. A hole 41 is provided from the front surface to the back surface of the platen cover 20, and a flat step portion 44 is formed at an intermediate portion of the hole 41. The screw 30 is a stepped screw and includes a screw head 37, a step portion 38, and a shaft portion 39. The diameter of each part becomes smaller in the order of the screw head 37, the step part 38, and the shaft part 39. When the screw 30 is tightened, the shaft portion 39 is squeezed while rotating along the screw groove 40. The stepped portion 38 and the surface of the platen 12 abut on the contact surface 42. A gap is formed between the back surface 43 of the screw head 37 and the flat portion 44. The side surface of the screw head 37 is configured not to contact the hole 41.

  In this modification, the platen cover 20 is fixed to the platen 12 so as to be movable by the size of the gap between the screw 30 and the platen cover 12. When the platen 12 and the platen cover 20 have different coefficients of thermal expansion, there is a problem that the platen cover 20 is warped and deformed if the platen 12 and the platen cover 20 are firmly connected. The system is stopped so that a gap is formed so as not to warp. In another form, the platen 12 and the platen cover 20 may be fixed more firmly by not providing a gap between the back surface 43 and the flat portion 44. Further, a washer may be provided between the back surface 43 and the flat portion 44.

  FIG. 8 is a view showing a second modification of the platen cover fixing means of the ink jet recording apparatus according to the preferred embodiment of the present invention.

  The screw head 45 of the screw 30 is configured to be recessed below the surface of the platen cover 20. The platen cover 20 includes a hole 49 with a tapered portion 48. The screw 30 includes a screw head 45 and a shaft portion 46. The platen 12 is provided with a thread groove 47. When the screw 30 is tightened, the platen cover 20 is fixed to the platen 12. The screw head 45 has a shape corresponding to the tapered portion 48, and the upper portion of the screw head 45 is below the surface of the platen cover 20.

  In this modified example, since the screw 30 does not contact the recording medium 17, smooth conveyance is possible. Further, since the platen 12 and the platen cover 20 are fixed by screws 30, it is desirable that the respective parts are preferably made of materials having the same thermal expansion coefficient. This is to prevent deformation of the platen cover 20 by heating.

  FIG. 9 is a view showing a third modification of the platen cover fixing means of the ink jet recording apparatus according to the preferred embodiment of the present invention.

  This is an example in which no screw is used for the fixing means. A flange 49 is formed by further bending the tip of the first bent portion 25 of the platen cover 20. The first recess 26 has a narrow opening and a wide inside. The platen cover 20 is fixed to the platen 12 by stopping the system so that the first bent portion 26 and the flange portion 49 are applied to the first concave portion 26. Similarly, the second bent portion 28 is provided with a collar portion and is fixed to the second concave portion 29 and fixed. Since it is not necessary to use parts such as screws, the number of parts can be reduced and the platen cover 20 can be easily replaced. The platen cover 20 is slidable in a direction perpendicular to the conveyance direction of the recording medium 17 along the first recess 26 and the second recess 29. The platen cover 20 can be moved according to the recording position on the recording medium 17.

  FIG. 10 is a block diagram of an ink jet recording apparatus according to a preferred embodiment of the present invention. The ROM 61 is a storage unit that stores data such as a program for controlling the operation of the entire inkjet recording apparatus and initial setting values. The control unit 60 is a control unit that performs processing such as comparison, calculation, and control according to a program stored in the ROM 61, and is, for example, a CPU. The RAM 62 is a storage unit used for temporary storage of various data, a work area used for calculation of the control unit 60, and the like. The input unit 63 is an input unit such as a switch for inputting a signal to the control unit 60. The display unit 64 is a display unit such as an LDC panel, and displays numbers and characters under the control of the control unit 60. The operation of the suction fan 16 is controlled by the control means 60. The operation of the print recording apparatus 2 is controlled by the control means 60. The operation of the transport roller 9 is controlled by the control means 60. The heater 65 is a heater for heating the platen, for example, a resistance wire, and the operation is controlled by the control of the control means 60.

  FIG. 11 is a flowchart of the operation of the ink jet recording apparatus according to the preferred embodiment of the present invention. This shows the operation when the platen cover 20 is selected and mounted according to the type of recording medium. When this process is started, first, the type of recording medium to be used is selected. The recording medium to be used is input from the input means 63 (step 70). The ROM 61 stores in advance information that associates the types of recording media to be used with the types of platen covers that are optimal for them. In addition to the optimum platen cover, information on platen covers that should not be used is also stored corresponding to the type of recording medium. The ROM 61 also stores information on the optimum suction force of the suction fan 16 and information on the heater temperature of the heater 65 according to the type of platen cover and the type of recording medium. Based on the type of the input storage medium, optimum platen cover information and platen cover information that should not be used are searched (step 71). Next, the platen cover information as a result of the search is displayed on the display means 64. At this time, the optimum platen cover and the platen cover that should not be used are displayed separately (step 72). At this time, the information on the platen cover that is optimal may be attached, but information on the platen cover whose performance is reduced may be displayed in order. At this time, rank information to be displayed in order may be stored in the ROM 61 in advance, and control may be performed so that the rank information is sorted at the same time as the search in step 71.

  Attach the platen cover according to the displayed information of the optimum platen cover. When the mounting is completed, information on the type of the platen cover mounted is input from the input means 63 (step 73). Alternatively, a platen cover that can be mounted is mounted, and information regarding the type of the platen cover is input. At this time, since there is a display of a platen cover that should not be attached, it is possible to prevent the wrong attachment. As another aspect, a convex portion is provided according to the type of the platen cover, a switch is provided at a position corresponding to the convex portion, the switch input is input to the control means 60, and the ROM 61 stores the type of the platen cover and the switch in advance. By storing the relationship, the platen cover that is automatically mounted may be determined according to the input of the switch. This switch input may be replaced with an input from the input means 63.

  Next, when the mounting of the platen cover is completed and information on the mounted platen cover is input, the process proceeds to the next. The control means 60 searches for information on the optimum suction force of the suction fan 16 and the optimum heater temperature of the heater 65 based on the input information of the recording medium to be used and the platen cover attached. Then, the suction fan 16 and the heater 65 are controlled by the control means 60 based on the retrieved information (step 74). This is the end of this process.

  As described above, when the type of the recording medium to be used is input and the type of the platen cover to be actually mounted is input, the optimum suction and platen temperature can be obtained. For example, the type of the platen cover 20 includes a difference in the length of the communication hole 19 in the short direction, that is, a difference in the area of the opening, depending on the type of the recording medium. By changing it according to the type of the sheet, it becomes possible to carry out optimum conveyance.

  The ink jet recording apparatus and the recording method of the present invention can be used for a general ink jet recording apparatus.
