Description

  The present invention relates to an absorber for an absorber of a liquid ejecting apparatus, a method for incorporating the absorber, and a liquid ejecting apparatus.

  Conventionally, an ink jet printer (hereinafter simply referred to as a printer) is widely known as a kind of liquid ejecting apparatus. In this printer, ink as liquid is ejected (discharged) from nozzles of a recording head as a liquid ejecting head, and recording (printing) is performed on a recording medium (for example, printing paper). The ink is stored in an ink cartridge (liquid container) and supplied from the ink cartridge to the recording head.

  As such a printer, there is a so-called off-carriage type in which an ink cartridge is not mounted on a carriage. In an off-carriage type printer, an ink cartridge containing an ink bag for storing ink is used, and the ink bag is pressurized by pressurizing the inside of the ink cartridge with air or the like. Then, the pressurized ink in the ink bag is supplied to the recording head via a lead-out needle inserted into the ink cartridge outlet.

  In such an off-carriage type printer, it is necessary to take out the lead-out needle from the outlet when replacing the ink cartridge. For this reason, there is a possibility that ink leakage occurs every time the ink cartridge is replaced. Various liquid ejecting apparatuses including means for collecting ink leaking in this way have been proposed (for example, Patent Document 1).

In the printer of Patent Document 1, a lead-out needle and an absorber that can move with respect to the lead-out needle are disposed in a cartridge holder that serves as a storage container for storing an ink cartridge. The absorber in the cartridge holder moves near the lead-out needle when the lead-out needle is withdrawn from the ink cartridge outlet, and absorbs and collects ink leaking from the lead-out needle.
Japanese Patent Laid-Open No. 11-70663

  However, although the above-described cartridge holder can prevent contamination due to ink leaking from the lead-out needle, the following problems arise because the inside of the ink cartridge is pressurized in the atmosphere and the stored ink is supplied to the recording head. That is, when pressurized air remains in the ink cartridge from which the lead-out needle has been removed, the ink in the ink cartridge is pushed out by the remaining air and leaks from the ink cartridge. As a result, there is a problem that the ink leaking from the ink cartridge contaminates the cartridge holder and thus the printer.

  In order to solve this problem, the applicant of the present application reciprocates between an insertion position for inserting a lead-out needle for attaching an ink cartridge and drawing out ink from the ink cartridge, and a pull-out position for pulling out the lead-out needle from the ink cartridge. A configuration in which a slider is provided and an absorber is provided on the slider has been considered. If the shape of the absorber is a simple plate shape, there is no problem in manufacturing or assembling of the absorber. However, when the shape of the absorber is complicated, it is necessary to configure the absorber by combining a plurality of absorbers. In that case, if each absorbent material is produced independently, there are problems that the number of man-hours is increased and errors in assembling into the slider are increased. In addition, the absorber is not limited to the absorber provided in the slider, and there is a similar problem in the case of a complicated shape even if the absorber is used in other parts of the liquid ejecting apparatus.

  The present invention has been made in view of the above problems, and the object thereof is to simplify the manufacturing process of an absorbent body constituted by combining a plurality of absorbent materials, and to improve the assemblability. An object of the present invention is to provide an absorbent material for an absorbent body of a liquid ejecting apparatus and a method for incorporating the absorbent body, which facilitates component management.

Therefore, the manufacturing process can be simplified as compared with a case where a plurality of absorbent materials having the same thickness constituting the absorber are manufactured independently one by one. Further, when assembling (incorporating) the absorbent body, it is possible to prevent mistakes in the number of absorbent materials having the same thickness necessary for the construction of the absorbent body, thereby eliminating an assembly error. Moreover, management of components (absorbent material) becomes easier as compared with the case where each absorbent material constituting the absorber is managed independently.

  In the absorbent material for an absorber of the liquid ejecting apparatus of the present invention, the plate material is provided with a cutting line for division. Therefore, each absorbent material can be easily divided from the plate material along the cutting line, that is, separated.

In the absorbent material for an absorbent body of the liquid ejecting apparatus of the present invention, the cutting line is formed in a perforated shape. Therefore, it becomes easy to form a cutting line on the plate.
In the absorbent for an absorbent body of the liquid ejecting apparatus of the present invention, the absorbent body has an absorbent material having a different thickness as a constituent element, and a plurality of the absorbent bodies having different thicknesses necessary for the configuration of the absorbent body One set of plate material was used for the absorber. Therefore, even when the absorbent body is not composed of only the absorbent material having the same thickness but is composed of a combination of absorbent materials having different thicknesses, it is possible to use all of the absorbent material constituting one set. Since the absorber is configured, it is easy to prevent assembly errors.

  In the absorbent material for an absorber of the liquid ejecting apparatus of the present invention, each absorbent material is provided with a mark indicating the order in which the absorbent material is installed in the accommodating portion equipped in the liquid ejecting apparatus. Therefore, even if the absorbent body has a complicated shape, the absorbent material can be efficiently incorporated into the housing portion.

  The method for assembling an absorber according to the present invention is a method for assembling an absorber composed of a plurality of absorbers into a storage unit equipped in a liquid ejecting apparatus, wherein the absorber has the same thickness among the plurality of absorbers. The material is integrally formed so as to be divided into one plate material.

Therefore, it is possible to prevent mistakes in the number of the absorbents having the same thickness necessary for the configuration of the absorber, and to eliminate an assembly error.

  In the assembling method of the absorbent body according to the present invention, each absorbent material is provided with a mark indicating the order of incorporation into the housing portion, and the absorbent material is assembled into the housing portion in the order indicated by the mark. Therefore, even if the absorbent body has a complicated shape, the absorbent material can be efficiently incorporated into the housing portion.

Next, the absorber 60 will be described in detail. FIG. 7A is a perspective view of the absorber 60.
The absorber 60 is configured by combining a plurality (9 in this embodiment) of absorbers 61, 62a, 62b, 62c, 63a, 63b, 63c, 63d, and 63e. The absorbent body 60 is in a state shown in FIG. 7A in a state where the absorbent members 61, 62a to 62c, 63a to 63e are in contact with each other in a state where the absorbent members 61, 62a to 62c and 63a to 63e are incorporated in the accommodation space 34. The absorbent body 60 includes absorbent materials having different thicknesses, and in this embodiment, the absorbent body 60 is composed of absorbent materials having three thicknesses.

  The absorbent material 61 has the smallest thickness, and no other absorbent material constituting the absorbent body 60 has the same thickness. The three absorbent materials 62a to 62c are formed with the thickest thickness, and the five absorbent materials 63a to 63e are formed with an intermediate thickness. The absorbers 63a to 63c are formed in the same outer shape.

  Although the absorbent material 61 and the absorbent material 62a have different thicknesses, they are formed in the same outer shape, and are incorporated into the accommodation space 34 in contact with each other. An insertion hole 64 is formed in the absorbent material 61 and the absorbent material 62a. The insertion hole 64 is a circular hole having an inner diameter substantially the same as the outer diameter of the support portion 26 a of the lead-out needle 26, and is formed in the slider 33 in a state where the absorber 60 is accommodated in the accommodation space 34. It is formed at a position opposite to the hole. By forming the insertion hole 64, the lead-out needle 26 can penetrate the absorber 60 through the insertion hole 64 and enter the cartridge 50.

  The absorbents having the same thickness, that is, the absorbents 62a to 62c and the absorbents 63a to 63e, as shown in FIG. 7B, are integrally formed so as to be divided into plate members 62 and 63 each having a constant thickness and an absorbing function. Has been. The plate members 62 and 63 are provided with cutting lines 65 for division. In this embodiment, the cutting line 65 is formed in a perforated shape. When the absorbent materials 62 a to 62 c and the absorbent materials 63 a to 63 e are incorporated into the accommodation space 34, the absorbent materials 62 a to 62 c and the absorbent materials 63 a to 63 e are assembled from the plate members 62 and 63 and then incorporated into a predetermined position in the accommodation space 34.

  In this embodiment, one absorbent material 61 and the plate materials 62 and 63 constitute an absorbent material for an absorbent body of a liquid ejecting apparatus that constitutes one absorbent body 60 in one set. That is, one set of a plurality of plate members 62 and 63 matched to the absorbers having different thicknesses necessary for the configuration of the absorber 60 is used for the absorber. In addition, since there is one absorbent material 61, the absorbent material 61 itself becomes a plate material.

  Each absorbent material 61, 62 a to 62 c, 63 a to 63 e is provided with a mark 66 indicating the order of incorporation into the accommodation space 34. In this embodiment, an Arabic numeral starting from 1 and increasing by 1 is provided as the mark 66.

  The plate members 62 and 63 are formed by processing a rectangular plate member having a predetermined thickness having an absorption function into a shape in which the absorbent members 62a to 62c and the absorbent members 63a to 63e are continuous by pressing or the like, and then processing the cutting line 65 with a blade. Is produced.

  When the absorber 60 is incorporated into the slider 33, one set of absorber material is used. The absorbent material 61 is left as it is, and the other absorbent materials 62a to 62c and the absorbent materials 63a to 63e are divided after the plate materials 62 and 63 are divided into individual absorbent materials 62a to 62c and absorbent materials 63a to 63e, or divided. However, it is incorporated into a predetermined position of the accommodation space 34.

Next, the operation of the cartridge holder 20 configured as described above will be described.
When the cartridge 50 is inserted from the insertion port 23, the cartridge 50 is guided into the holder case 21 with both the upper and lower surfaces being in contact with and supported by the rails 24. As shown in FIG. 4, when the cartridge 50 is inserted to the middle of the holder case 21, the positioning projection 37 of the slider 33 is fitted into the positioning hole 56 of the connection surface 50 a of the cartridge 50. As a result, the cartridge 50 is positioned with the connection surface 50 a facing the mounting surface 33 a of the slider 33. Further, the connection surface 50 a of the cartridge 50 contacts the exposed portion 60 a of the absorber 60 of the slider 33.

  Further, the insertion hole 64 of the absorber 60 faces the take-out portion 53 of the ink pack 52 exposed from the connection surface 50a. Further, the cartridge holder 20 makes the guide hole 39 of the slider 33 face the air introduction hole 55 of the cartridge 50. Thereby, the needle portion 26 b of the lead-out needle 26 is opposed to the take-out portion 53 of the cartridge 50, and the contact member 32 of the air introduction member 28 is opposed to the air introduction hole 55.

  Next, when the cartridge 50 is further pushed into the holder case 21 from the state shown in FIG. 4, the slider 33 is pushed together with the cartridge 50 toward the rear wall 21 b of the holder case 21. Then, the needle portion 26 b of the lead-out needle 26 of the cartridge holder 20 is inserted into the take-out port 53 a of the take-out portion 53 of the cartridge 50. Further, the contact member 32 of the air introduction member 28 contacts the connection surface 50 a of the cartridge 50, and the communication hole communicates with the air introduction hole 55. At this time, if the cartridge holder 20 has the lead-out needle 26 inserted therein and ink leaks from the take-out port 53a, the cartridge holder 20 absorbs the ink through the exposed portion 60a that is in close contact with the connection surface 50a of the cartridge 50. 60 to absorb.

  When the push-in of the cartridge 50 is stopped, the cartridge 50 is held in a state in which movement in the direction of the insertion port 23 is restricted by the fixing means. As shown in FIG. 5, the cartridge 50 is held in a state in which the connection surface 50a is in close contact with the exposed portion 60a of the absorber 60 of the slider 33 and the outlet needle 26 is inserted into the take-out port 53a. At this time, since the slider 33 is in contact with the cartridge 50, the movement in the direction of the insertion port 23 is restricted. In this state, when the pressurized air generated by the pressure pump P disposed in the frame 2 is introduced into the cartridge 50 via the air introduction member 28, the ink pack 52 of the cartridge 50 is pressurized. The The ink pack 52 guides the stored ink to the flow path forming member 9 via the lead-out needle 26. As a result, each ink is supplied to the recording head 8 via the flow path forming member 9 and the ink supply tube 10, and printing is performed on the recording paper.

It is integrally formed. Therefore, the manufacturing process can be simplified as compared with the case where a plurality of absorbent materials 62a and the like having the same thickness constituting the absorber 60 are independently manufactured one by one. Further, when assembling (incorporating) the absorbent body 60, it is possible to prevent mistakes in the number of the absorbent members 62a having the same thickness necessary for the structure of the absorbent body 60, thereby eliminating an assembly error. Furthermore, compared to the case where the absorbent materials 62a, 63a, etc. constituting the absorbent body 60 are managed independently, the management of parts (absorbent materials) becomes easier.

(2) The plate members 62 and 63 are provided with a cutting line 65 for division. Therefore, it is possible to easily divide the absorbent members 62a, 63a and the like from the plate members 62, 63 along the cutting line 65.
(3) Since the cutting line 65 is formed in a perforated shape, the cutting line 65 can be easily formed on the plate members 62 and 63.

  (4) The absorbent body 60 includes absorbent members 61, 62a, 63a and the like having different thicknesses, and a plurality of plate members 62 adapted to the absorbent materials 62a, 63a and the like having different thicknesses necessary for the configuration of the absorbent body 60. , 63 is one set for the absorber 60. Therefore, even when the absorbent body 60 is not composed of only the absorbent material having the same thickness but is composed of a combination of absorbent materials having different thicknesses, the absorbent material constituting one set should be used. Since the absorber 60 is constituted by this, it becomes easy to prevent an assembly error.

  (5) The method of assembling the absorber 60 into the accommodating portion (accommodating space 34) is made of the absorbers 62a to 62c and the absorbers 63a to 63a having the same thickness among the plurality of absorbers 61, 62a to 62c and 63a to 63e. 63e is integrally formed so that it can be divided into one plate material 62, 63, respectively. Then, at the time of incorporation into the housing portion, the absorbent material 62a and the like are divided from the plate material and incorporated into the housing portion. Therefore, it is possible to prevent the mistake in the number of the absorbents having the same thickness necessary for the configuration of the absorber 60, and to eliminate an assembly error.

  (6) Each absorbent material 61, 62a to 62c, 63a to 63e is provided with a mark 66 indicating the order in which the absorbent material 61, 62a to 62c and 63a to 63e are assembled into the accommodating portion (accommodating space 34). , 63a to 63e are incorporated in the accommodating portion. Therefore, even if the absorbent body 60 has a complicated shape, the absorbent materials 61 and 62a and the like can be efficiently incorporated into the housing portion.

(7) An Arabic numeral starting from 1 and increasing by 1 is provided as the mark 66. Therefore, the assembling order can be easily understood.
(8) When the absorbers 61, 62a, 63a and the like constituting the absorber 60 satisfy any of the constituent requirements (1) to (7), the shape of the absorber 60 used in the printer 1 is changed. Even if it is complicated, the absorber 60 can be incorporated without assembling mistakes. Therefore, the degree of freedom of the shape of the absorber 60 for effectively using the space of the cartridge holder 20 is increased.

In addition, you may change embodiment as follows.
-Although the number of the insertion holes 64 formed in the absorber 60 is one normally, it is not restricted to one. For example, as shown in FIG. 8, a configuration in which two insertion holes 64 are provided may be adopted. This configuration corresponds to the configuration of the cartridge holder 20 including the two lead-out needles 26 so that the cartridge 50 having the configuration in which the two ink packs 52 are accommodated can be used. Such a cartridge 50 may be used for a large amount of ink used, for example, black ink.

  -The absorber 60 should just be comprised combining a some absorber, The shape is suitably changed according to the shape of not only the shape of the said embodiment but the accommodating part (accommodating space 34). The Further, instead of using a part of the absorber 60 as the exposed portion 60a protruding from the mounting surface 33a of the slider 33, the side of the absorber 60 facing the mounting surface 33a of the slider 33 is a surface as shown in FIG. It may be one. Then, the peripheral edge of the attachment hole 54 of the connection surface 50 a of the cartridge 50 is projected so as to be in contact with the absorber 60. In this case, the absorbent body 60 is formed of two kinds of absorbent materials 62 a to 62 c and 63 a to 63 e, and one set constituting the absorbent body 60 is composed of two plate members 62 and 63. Moreover, depending on the shape of the absorber 60, it is also possible to form all the absorbers which comprise the absorber 60 in the same thickness. In that case, 1 set which comprises the absorber 60 is comprised with one board | plate material.

  The cutting line 65 formed on the plate members 62 and 63 is not limited to the perforated shape, and it is only necessary to divide (separate) each absorbent material 62a, 63a, etc. It may be formed at a predetermined depth.

  The cartridge holder 20 is not limited to a configuration in which the cartridge 50 is stored in an upright state, and may be configured to store the cartridge 50 in a horizontal state. In this case, the cartridge holder 20 may be arranged in a stacked state or arranged side by side.

  The slider 33 is not limited to the configuration of the embodiment described above, and the position where the cartridge 50 can be mounted on the slider 33, and the needle portion 26 b of the lead-out needle 26 of the cartridge 50 mounted on the slider 33 is the take-out portion 53 of the ink pack 52. It suffices if it can be moved to a position where it is inserted into the position. For example, as a configuration for urging the slider 33 toward the insertion opening 23 of the holder case 21, a configuration using a compression spring that urges the slider 33 from the surface 33b side may be used instead of the configuration using the tension spring 41. .

  The absorber 60 is not limited to the one housed in the housing space 34 of the slider 33, and may be applied to one that is housed and used in a housing portion provided at another location. For example, as the storage unit, there is a waste ink tank that stores waste ink sucked by an ink pump or ink ejected when the recording head performs preliminary ejection in order to prevent clogging of the recording head. .

  The present invention is embodied in a printer in which the cartridge 50 is not mounted on the carriage 7, that is, the off-carriage type printer 1, but may be embodied in a so-called on-carriage type printer in which the cartridge 50 is mounted on the carriage.
