<P>PROBLEM TO BE SOLVED: To provide a tube holder, an ink supply piping system for an ink-jet printer, and an ink-jet printer that make a pressure loss in a pipe conduit reaching each ink-jet head uniform and minimum. <P>SOLUTION: The tube holer 403 is provided at a corner in a piping path of a tube for supplying ink to the ink-jet head from an ink tank so as to hold the tube. The tube holder 403 has a holder body 411 which is formed into a curved shape in a plane view along the corner, and a tube holding groove 412 formed on the upper face of the holder body 411 so as to hold the tube bent along the corner. <P>COPYRIGHT: (C)2007,JPO&INPIT
Each tube is composed of a hard resin tube, and is connected via a joint (elbow) at a corner portion of the piping path.
The tube holder of the present invention is a tube holder that is provided at a corner in a piping path of a tube that supplies ink from an ink tank to an inkjet head, and that holds the tube, and is a holder formed in a substantially curved shape in plan view along the corner It has a main body and a tube holding groove formed on the upper surface of the holder main body to hold the tube in a bent state along the corner.
In this case, it is preferable that a plurality of tubes are arranged side by side in the piping path, and a plurality of tube holding grooves are formed side by side in the holder body.
According to this configuration, piping can be performed at the corner portion of the piping path in a state where a plurality of tubes are aligned and bent.
In this case, it is preferable that the plurality of tube holding grooves are formed with the same radius of curvature.
According to this configuration, the pipe line condition of the portion bent by the tube holding groove of each tube can be made the same, and the pressure loss in the plurality of tubes can be made exactly the same.
In these cases, it is preferable that the tube holding groove is formed to a depth at which a plurality of tubes can be stacked and held.
In these cases, it is preferable that the tube holding groove is composed of a curved portion and two linear portions respectively connected to both ends of the curved portion.
Although not specifically shown, the X-direction detection sensor that detects the reference position of the head unit 24 in the X-axis direction (home position, left side in the figure: the X-axis origin) and the Y-axis direction of the head unit 24 via the X-axis table 27. And a Y-direction detection sensor for detecting a reference position (home position, rear side in the drawing: origin of Y axis). When the main power supply of the ink jet printer 1 is turned on, the XY movement mechanism 25 is always reset to this reference position.
The tape feed roller 111 is composed of a drive roller 123 and a driven roller 124 having a grip roller structure facing each other with the printing tape A interposed therebetween. A tape feed motor 112 is connected to the drive roller 123, while the driven roller 124 is interposed. The spring 125 is biased toward the driving roller 123. The tape feed motor 112 is composed of a stepping motor and is connected to the controller 11 to control the rotation of the tape feed roller 111.
As shown in the enlarged views of FIG. 12 and FIG. 15, the width guide portion 117 includes a bottom plate 133 fixed on the base plate 13, and a front mounting plate 134 erected and spaced from the bottom plate 133 in the front-rear direction. And a fixed guide plate 135 on the rear side, a moving guide plate 136 configured to be movable between the mounting plate 134 and the fixed guide plate 135, and a plurality of both ends supported by the mounting plate 134 and the fixed guide plate 135. A (five) feed member 137 and a plurality (two) of plate guides 138 and a leaf spring part 139 for applying tension to the printing tape A are provided, and the fixed guide plate 135 and the movable guide plate 136 are paired. The width of the printing tape A fed to the machine base 2 is regulated.
Therefore, for example, for a printing tape A having a width of 70 mm, a comb-like slide composed of a 47-mm flat-plate-sliding contact portion 161 and two 7 mm comb-tooth pieces 163 and 163 adjacent to each other. The contact part 162 is in sliding contact with each other, and tension is applied at a position away from each end face in the width direction of the printing tape A by a predetermined distance (1.5 mm). As a result, the plate-like sliding contact portion 161 and the comb-like sliding contact portion 162 are set within the paper width with respect to the corresponding printing tape A, so that the leaf spring 152 does not contact the end face of the printing tape A. And since the both ends of the width direction of each printing tape can be pressed down effectively, suitable tension can be given to the printing tape of each width. In addition, the length of the comb-tooth piece 163 is 15 mm.
Next, the tape winding means will be briefly described with reference to FIG. The tape take-up means 8 includes a tape take-up reel 191 that is rotatably supported by the finisher body 20, a take-up roller 192 positioned immediately above the tape take-up reel 191, and a take-up roller that rotates the take-up roller 192. Between the finisher 3 and the machine base 2, the take-up motor 193, the take-up guide roller 194 that approaches and faces the take-up roller 192, the width regulating portion 195 that regulates the width direction of the printed printing tape A, And a presser roller 196 positioned in the position. The printed printing tape A sent from the tape feeding means 7 is guided to the width restricting portion 195 via the press roller 196, where the width guide for the tape winding is performed, and the tape take-up reel 191 is wound up into a roll.
The width restricting portion 195 has a structure similar to that of the width guide portion 117 provided on the upstream side of the tape feeding means 7 and feeds the printing tape A in a wave shape and operates a push rod 198 provided so as to protrude forward. It is possible to correspond to the printing tape A of each width. The winding roller 192 includes a driven roller and a driving roller that are opposed to each other with the printing tape A interposed therebetween. The driving roller is connected to a winding motor 193 and is urged toward the driving roller by a spring 197 provided with the driven roller. ing. The operation panel 22 is used to adjust the tape winding torque so that the printing tape A is properly wound on the tape winding reel 191.
Although both will be described in detail later, the insertion hole 246 is for preventing erroneous mounting of the ink cartridge 216, and an insertion pin 283 provided in the pressure tank 217 is inserted therein. In addition, in order to prevent erroneous mounting of the ink cartridge 216 of an ink color different from the corresponding one to the pressurized tank 217, the lower end wall 244 of the case side joint 241 has a notch 250 (for each ink color) (Predetermined two pieces) are formed, and the pressure tank 217 is provided with insertion protrusions 284 (predetermined two pieces) to be inserted into the notch portion 250. Reference numeral 251 in FIG. 20 denotes an ink absorber 251 placed on the upper surface of the lower end wall 244 at the lower side of the ink supply port 224, and ink leaking as the ink cartridge 216 is attached / detached. It is designed to absorb.
Next, a main control system constituted by the controller 11 will be described. As shown in the block diagram of FIG. 29, the control system of the ink jet printer 1 includes an input unit 451 that reads (inputs) image data created by an external device such as a personal computer by the operation, and a printing unit 5. A printing unit 452 that prints an image on the printing tape A, a maintenance unit 453 that includes the maintenance unit 10 and performs maintenance processing of the inkjet head 26, and an ink supply unit 9 that supplies ink to the inkjet head 26. An ink supply unit 454, a tape supply unit 6 (supply motor 183), a tape feed unit 7 (tape feed motor 112), and a tape take-up unit 8 (winding motor), and a transport unit 455 for feeding the printing tape A , A drive unit 456 having various drivers for driving each unit, and a tape feed center of the sub controller 385 and the tape feed means 7. A detection unit 457 for performing various detections have 130 etc., and a control unit 458 for controlling each unit of the ink jet printer 1 (controller 11).
In each of the above-described embodiments, the pair of grip rollers 115 (115a, 115b) is provided. However, the grip roller 115 may be composed of only one roller. For example, the grip roller 115 may be configured only by a roller (115a) whose roller rolling surface with respect to the printing tape A is horizontal with the surface of the suction table 101 (suction plate 105).
