Description

The present invention relates to an ink jet recording apparatus, and more particularly to an ink jet recording apparatus that supplies an electric signal, ink, or the like to a recording head via wiring or piping accommodated in a cable bear (registered trademark, the same applies hereinafter) .

  Provided on one end of the recording head as an image recording apparatus capable of recording images not only on ordinary recording media such as paper and fabrics but also on recording media with poor ink absorption such as resin films and metals. An ink jet recording apparatus has been developed in which ink is ejected from the nozzles and landed on a recording medium, and the technology is currently applied in various technical fields.

  In such an ink jet recording apparatus, a wiring for transmitting an electric signal or power to the recording head, a grounding wire for grounding the recording head (hereinafter also referred to as wiring), or a liquid ejected from a nozzle of the recording head is used. A pipe that supplies the recording head is connected to the recording head. Ink jet recording apparatuses are usually equipped with a plurality of recording heads, and the number of recording heads is relatively large particularly when performing color image recording using a plurality of color inks.

  Therefore, the number of wires and pipes connected to these multiple recording heads increases, and they become entangled, disturbing assembly when the device is assembled. The ink supply pressure in the ink fluctuates, which causes an obstacle such as that ink supply to the recording head cannot be normally performed. In particular, when the ink jet recording apparatus is a serial head type apparatus, the recording head is mounted on the carriage and reciprocates in the main scanning direction, so that the piping and wiring rub against each other and the wiring is disconnected or damaged. As a result, problems arise such as holes opening and ink leaking out of the piping.

Therefore, for example, Patent Document 1 proposes that a plurality of pipes are bonded or integrally formed and arranged side by side, and a flexible printed board is used as the wiring, and they are arranged side by side. In Patent Document 2 and Patent Document 3, it is proposed that a plurality of pipes are bundled side by side with a bundling tool, and an intermediate material such as a sponge layer is interposed between the flat cable and the side-by-side pipes.

  However, the invention described in Patent Document 1 can be applied to a home printer or the like using a small number of printheads and a relatively small number of pipes, but has a large number of printheads and a large number of pipes and wirings. In addition, it is practically difficult to apply this to a large-scale business-use ink jet recording apparatus in which the range of reciprocation of the carriage is wide and long pipes and wirings are provided.

  Further, in the inventions described in Patent Document 2 and Patent Document 3, since the piping is bound by the binding tool, the piping and the binding tool rub against each other when the piping moves in accordance with the reciprocating movement of the carriage. There is a case where the piping is damaged by the tight binding portion due to the ink and the ink leaks from the piping.

  Further, in Patent Documents 1 to 3, it is proposed to use a flexible printed circuit board or the like as the wiring. However, the wiring connected to the recording head is not limited to this, but a normal cable connection or the like. It is convenient if it is configured so that it can be used.

  The present invention has been made in view of the above problems, and provides an ink jet recording apparatus capable of reliably preventing damage to wiring for transmitting an electrical signal to a recording head and piping for supplying a liquid. With the goal.

  According to the ink jet recording apparatus of the present invention, wiring for transmitting an electrical signal to the recording head and piping for supplying liquid to the recording head are accommodated in the cable bear, and the cable bear is flexible and has a smooth surface. A partition wall made of a flat plate material is provided so that wiring and piping are accommodated on the front surface side and back surface side of the partition wall, respectively, so that the wiring and piping, the wirings or the pipings are intertwined and rubbed, or the wiring and piping It is possible to reliably avoid rubbing with the partition walls and reliably preventing the wiring and piping from being broken or the piping from being damaged to cause holes to open and ink to leak out.

  In addition, even if the wiring and piping are not tied up with the cable track, the position of the wiring and piping within the cable track is maintained properly. It can be effectively prevented.

  Embodiments of an ink jet recording apparatus according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the ink jet recording apparatus 1 according to the present embodiment mainly includes a transport unit 2, a scan unit 3, an ink rack 4, and a computer 5.

  An endless transport belt 21 for transporting a recording medium (not shown) from the back side while transporting it in the sub-scanning direction Y indicated by an arrow Y in the drawing is disposed above the transport unit 2. Instead of the conveyor belt 21, a plate-like platen can be used. In the present embodiment, the transport unit 2 and the scan unit 3 are formed as separate bodies, but may be formed integrally.

  As described above, the recording medium is not particularly limited, and may be a resin film, metal, or the like in addition to paper and fabric.

  The scan unit 3 is disposed above the transport belt 21 of the transport unit 2. The scan unit 3 will be described in detail later.

  In the present embodiment, an ink rack 4 including an ink tank 41 for storing each color ink (liquid) supplied to each of a plurality of recording heads 8 to be described later is disposed behind the scan unit 3. Ink is supplied from each ink tank 41 to each recording head 8 via a pipe 15 described later.

  Also, below the scan unit 3, a computer 5 for controlling each part constituting the ink jet recording apparatus 1 is disposed, and an electrical signal is sent from the computer 5 to each recording head 8 via a wiring 11 to be described later. It is to be transmitted.

  FIG. 2 is a diagram illustrating a main part inside the scan unit. Note that there is actually a head moisturizing unit that caps the nozzle surface 81a of the recording head 8 and moisturizes it while the operation of the inkjet recording apparatus 1 is stopped, on the left pedestal portion of the scanning unit 3 in the figure. There is a maintenance unit in which a head cleaning mechanism and the like for performing maintenance of the recording head 8 are disposed on the pedestal portion, but the illustration is omitted in FIG.

  Inside the scan unit 3, a rod-shaped carriage rail 6 is arranged so as to extend in the main scanning direction X indicated by an arrow X in the figure perpendicular to the sub-scanning direction Y. A substantially housing-like carriage 7 is supported along the carriage rail 6 so as to be reciprocally movable in the main scanning direction X.

  As shown in FIG. 3, the carriage 7 has a nozzle surface 81a on which a plurality of nozzles 81 for ejecting ink of each color such as yellow (Y), magenta (M), cyan (C), and black (K) are arranged. A plurality of recording heads 8 are mounted, and ink droplets of each color are ejected from the nozzles 81 of the recording heads 8 to the recording medium S on the transport belt 21 of the transport unit 2. .

The upper end of the carriage 7 is connected to a cable bear 9 that flexibly deforms and follows the movement of the carriage 7 that reciprocates in the main scanning direction X and protects the wiring 11 and the pipe 15 accommodated therein. Yes. In this embodiment, the cable bearer 9, as shown in FIG. 4, are made form by connecting pieces 9a of the substantially square tubular with one another pivotally connecting member 9b.

  The upper end portion of the carriage 7 is formed in two layers, and on the upper layer side, a head drive circuit board 10 for driving and controlling each recording head 8 is disposed. A wiring 11 accommodated in the cable bear 9 is extended to the head drive circuit board 10 and the like, and is connected via a connector 12 and the like.

  In this case, a bundled wire in which a plurality of electric wires are bundled into one cable is used as the wire 11, and the wire 11 transmits electric power, an electric signal, and the like to the head drive circuit board 10 that drives the recording head 8. It is supposed to be. Further, the wiring 11 includes those ground wires.

  A plurality of ink supply pipes 13 for supplying ink to the respective recording heads 8 are arranged on the lower layer side of the upper end portion of the carriage 7, and a cable is connected to each ink supply pipe 13 via a joint 14. It is connected to each pipe 15 accommodated in the bear 9. The pipe 15 is connected to the ink supply pipe 13 in this way, so that the ink ejected from the nozzle 81 is supplied to the recording head 8.

  The head drive circuit board 10 and the like are heated by energization, and the air around the head drive circuit board 10 and the like is heated and rises. Further, when the ink is warmed in the pipe 15 or the ink supply pipe 13, a phenomenon occurs in which the ejection of ink from the nozzle 81 of the recording head 8 becomes unstable. Therefore, the head drive circuit board 10 and the like are arranged on the upper layer side as in the present embodiment so that the air heated by the head drive circuit board 10 and the like does not warm the ink in the pipe 15 and the ink supply pipe 13. The ink supply pipe 13 is preferably disposed on the lower layer side.

  In the present embodiment, a total of eight pipes 15 are accommodated in the cable bear 9, but each pipe 15 is accommodated in, for example, a resin tube 16 for each predetermined number. As shown in FIG. 5, it is also possible to configure each pipe 15 so as to be wound with a protective tape 17 for each predetermined number. In this way, by accommodating the pipe 15 in the tube 16 or winding it with the protective tape 17, it is possible to prevent the pipes 15 from being intertwined or rubbed together and being damaged, and easy to assemble. Assembling is improved.

  Further, as shown in the cross-sectional view of FIG. 6, in this embodiment, a total of eight pipes 15 in the cable bear 9 are accommodated in three tubes 16 in a group of three, two, and three, respectively. ing. In this way, by making the number of the pipes 15 accommodated in the plurality of tubes 16 as uniform as possible, the weight balance in the cable bear 9 can be stabilized, and the cable bear 9 can smoothly move in the reciprocating movement of the carriage 7. Since it follows, it becomes possible to further reduce the occurrence frequency of damage to the pipe 15 and the wiring 11. In FIG. 6, the internal structure of the wiring 11 is not described, but a plurality of electric wires are bundled in each wiring 11 as described above.

  As shown in FIGS. 4 and 6, the cable bear 9 is provided with a partition wall 18 that divides the inside thereof, and the wiring 11 is provided on the surface side of the partition wall 18 in the cable bear 9, and the pipe 15 and the tube 16 are provided. Each is accommodated on the back side of the partition wall 18 in the cable bear 9.

  Note that the wiring 11, the pipe 15, the tube 16, and the partition wall 18 are each fixed to the carriage 7 independently. That is, the wiring 11 is fixed to the carriage 7 by a bundled wire clamp (not shown). Further, the pipe 15 is actually covered with a coating material (not shown) such as a silicon tube which has an inner diameter smaller than the outer diameter of the pipe 15 and has flexibility, such as a silicon tube. Each pipe 15 is fixed to the carriage 7 by fixing A and its covering material and fixing the fixture A to the carriage 7.

  The tube 16 is fixed to the carriage 7 by a fixing member not shown in FIG. In order to fix the tube 16, a sponge-like cushioning material and a double-sided adhesive tape are attached to the fixing member. The partition wall 18 is fixed to the carriage 7 with screws (not shown).

  As described above, in the two-layer structure of the upper end portion of the carriage 7, the head drive circuit board 10 and the like are disposed on the upper layer side, and the ink supply pipe 13 is disposed on the lower layer side. The piping 15 is preferably housed on the upper surface side and the lower surface side of the partition wall 18 in the cable bear 9, and the cable bear 9 is preferably attached to the carriage 7 so as to have such a positional relationship. .

  With respect to the two-layer structure of the upper end portion of the carriage 7 as described above, the wiring 11 is accommodated on the lower surface side of the partition wall 18 in the cable bear 9 and the pipe 15 is accommodated on the upper surface side of the partition wall 18 in the cable bear 9. If configured in this way, the wiring 11 and the pipe 15 intersect each other, and rubbing may occur between them, so that such an arrangement is usually not taken.

  As described above, the pipe 15 is preferably accommodated on the end of the cable bear 9 on the side of the partition wall 18 in the cable bear 9 close to the recording head 8, that is, on the lower surface side of the partition wall 18 in this embodiment.

  Further, this is not only the case where the cable bear 9 bends or extends in the vertical direction as in the present embodiment, but also the cable bear 9 bends in the horizontal direction as in the ink jet recording apparatus described in Patent Document 1 described above. Similarly, when the pipe 15 is accommodated on the end of the cable bear 9 on the side close to the recording head 8 of the partition wall 18 in the cable bear 9, the pipe 15 and the wiring 11 cross each other. Can be avoided, which is preferable.

  The partition wall 18 has flexibility and is formed of a plate material having a smooth surface, and flexibly follows the flexible deformation of the cable bear 9.

  In the present embodiment, the partition wall 18 is formed of a stainless plate or a copper plate. Since the stainless steel plate and the copper plate are usually manufactured by rolling, the surface is smooth. However, if the surface is not smooth, it is preferable to perform a smoothing treatment. If the partition wall 18 is formed of a stainless steel plate, the partition wall 18 is hardly rusted, and it is possible to prevent the pipe 15 and the like from being rubbed and damaged by rust, which is preferable. Further, by configuring the partition wall 18 by a metal plate such as a stainless plate or a copper plate, the partition wall 18 can be used as a ground wire for the head drive circuit board 10 or the like.

  The partition wall 18 can be formed of a resin plate having a smooth surface such as Teflon (registered trademark) or PET (polyethylene terephthalate). By smoothing the surface of the partition wall 18 including the case where the partition wall 18 is formed of a metal plate, the wiring 11 and the piping 15 (or the tube 16 or the like) rub against the partition wall 18 to be broken or damaged. It becomes possible to prevent.

  Further, although not shown, it is possible to form a smooth layer on the surface of the partition wall 18 by coating one surface or both front and back surfaces of the partition wall 18 made of a metal plate with a resin. With this configuration, it is possible to ensure the smoothness of the surface of the partition wall 18 and to use the partition wall 18 as an earth line for the head drive circuit board 10 and the like.

  Further, as shown in FIG. 7, the partition wall 18 can be formed by a plurality of plate members (metal plate or resin plate) 18a and 18b arranged side by side. Further, as shown in FIG. A partition wall 18 is formed by interposing a member 19 having flexibility (hereinafter, referred to as a flexible material 19), such as a resin plate or sponge, between the plurality of provided plate materials 18a and 18b. It is also possible to form.

  The cable bear 9 bends and extends as shown in FIG. 9 following the reciprocation of the carriage 7 along the carriage rail 6 in the main scanning direction X. However, in the portion where the cable bear 9 bends, the wiring 11 Moves relative to the partition wall 18, and the pipe 15 also moves relative to the partition wall 18.

  At this time, as shown in FIG. 7, if the partition wall 18 is formed of a plurality of plate members 18a and 18b, the relative movement of the wiring 11 with respect to the plate member 18a is compared with the case where only one partition wall 18 is provided. In addition, the relative movement of the piping 15 with respect to the plate material 18b is reduced, and the degree of rubbing of the wiring 11 and the piping 15 with respect to the plate materials (partition walls) 18a and 18b can be reduced.

  Further, as shown in FIG. 8, by interposing the flexible material 19 between the plate materials 18a and 18b, it becomes possible to prevent the friction between the plate material 18a and the plate material 18b, and the plate materials 18a and 18b. The movement becomes smooth and the frictional noise generated between the plate members 18a and 18b can be silenced. Note that the plate members 18a and 18b and the flexible member 19 are not bonded to each other and can move freely.

  On the other hand, friction can also occur between the cable bear 9 and the wiring 11 and between the cable bear 9 and the pipe 15. Therefore, as shown in FIG. 10, it is preferable to dispose a plate member 20 (hereinafter referred to as a smooth plate 20) that is separate from the partition wall 18 and is flexible and has a smooth surface, as shown in FIG. If comprised in this way, it will become possible to prevent the wiring 11 or piping 15 and the cable bear 9 from rubbing, and it will become possible to prevent that the wiring 11 or piping 15 breaks, damages, etc.

  The smooth plate 20 is preferably formed of a stainless steel plate or a resin plate having a smooth surface, like the partition wall 18. It is also possible to provide the smooth plate 20 only between the cable bear 9 and the wiring 11 or between the cable bear 9 and the pipe 15.

  Next, the operation of the ink jet recording apparatus 1 according to this embodiment will be described.

  In the ink jet recording apparatus 1, during normal image recording, the carriage 7 moves on the recording medium S (see FIG. 3) along the carriage rail 6 in the main scanning direction X, and each recording is performed while the carriage 6 is moving. Ink droplets are ejected from each nozzle 81 of the head 8 in accordance with the ejection signal, and an image for one column is recorded on the recording medium S in the main scanning direction X.

  Then, the conveying belt 21 is operated to move the recording medium S by a predetermined amount in the sub-scanning direction Y, and the ink droplets of ink are ejected from the nozzles 81 of the recording heads 8 while the carriage 7 is moved again in the main scanning direction X. The image is ejected according to the ejection signal, and an image is recorded on the recording medium S. An image is recorded on the recording medium S while alternately repeating the scanning of the recording head 8 in the main scanning direction X and the conveyance of the recording medium S by the conveying belt 21 in the sub-scanning direction Y.

  When the carriage 7 reciprocates in the main scanning direction X, as shown in FIG. 9, the cable bear 9 connected to the carriage 7 bends and extends following the reciprocation of the carriage 7. However, as shown in FIG. 4, FIG. 6, and the like, the cable bear 9 is provided with a partition wall 18 that divides the inside, and the wiring 11 is connected to the surface side of the partition wall 18 in the cable bear 9. Since 15 is accommodated on the back side of the partition wall 18 in the cable bear 9, the wiring 11 and the pipe 15 are not entangled even if the cable bear 9 bends or extends. Therefore, there is no problem that the wiring 11 and the piping 15, the wirings 11, or the pipings 15 are entangled and rubbed with each other and broken, or the piping 15 is damaged and a hole opens to leak ink.

  In addition, since the partition wall 18 has flexibility, it flexibly follows the movement of the cable bear 9 and is formed of a smooth plate material. Therefore, the partition wall 18 is free from friction even when it slides on the wiring 11 and the pipe 15. It does not occur, or very little friction, if any. Therefore, there is no problem that the wiring 11 or the pipe 15 and the partition wall 18 are broken by sliding, or that the pipe 15 is damaged and a hole is opened to leak ink.

  Further, even when the ink jet recording apparatus 1 is assembled, the wires 11 and the pipes 15 may be entangled. In this case, the wires 11 are also inserted into the surface side of the partition wall 18 in the cable bear 9 and the back surface of the partition wall 18 is inserted. By inserting the pipes 15 on the side and accommodating them respectively, it becomes possible to avoid the entanglement between them, and there is no problem that the ink entangles and rubs and breaks or is damaged and ink leaks out.

  As described above, according to the ink jet recording apparatus 1 according to the present embodiment, the wiring 11 that transmits an electrical signal to the recording head 8 and the pipe 15 that supplies the liquid (ink) to the recording head 8 are provided in the cable bear 9. A partition wall 18 formed of a flexible and smooth surface plate is provided in the cable bear 9, and the wiring 11 and the pipe 15 are respectively stored on the front surface side and the back surface side of the partition wall 18. did.

  Therefore, the wiring 11 and the piping 15 are broken by accurately avoiding the wiring 11 and the piping 15, the wirings 11 and the piping 15 being intertwined and rubbing, or the wiring 11 and the piping 15 and the partition wall 18 rubbing against each other. It is possible to reliably prevent ink from leaking due to damage to the pipe 15.

  Further, when the cable bear 9 moves following the reciprocating movement of the carriage 7, the wiring 11 and the pipe 15 also move in the cable bear 9. For example, the left and right positions of the wirings 11 shown in FIG. As long as the left and right positions of the 15 are not interchanged, the wiring 11 and the pipe 15 are allowed to move in the cable bear 9.

  As described above, in the inkjet recording apparatus 1 according to the present embodiment, the wiring 11 and the pipe 15 are not bound by the cable bear 9 and the partition wall 18 and do not need to be bound. Therefore, even if the wiring 11 or the pipe 15 and the cable bear 9 rub against each other, the degree of rubbing is small compared with the case where the cable bear 9 binds them, and the wiring 11 or the pipe 15 is damaged by the cable bear 9. It can be effectively prevented.

  In the above embodiment, the case where the ink jet recording apparatus is a serial head type ink jet recording apparatus in which a recording head is mounted on a carriage and performs image recording while reciprocating in the main scanning direction has been described. However, the present invention is not limited to this, and the present invention is also applicable to a line head type ink jet recording apparatus that performs image recording by ejecting ink onto a recording medium transported downward from a recording head whose position is fixed.

  Also in the line head type ink jet recording apparatus, wiring for transmitting an electrical signal to the recording head and piping for supplying liquid such as ink are accommodated in the cable bear and connected to the recording head. When the recording head is moved from the recording position during maintenance, wiring and piping may be entangled. At this time, if the present invention is applied, the same effects as those of the serial head type inkjet recording apparatus 1 of the above-described embodiment can be obtained.
