Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, remanufacturing of cartridges has been demanded from the perspective of realizing a sustainable society such as a decarbonized / circular society. In the remanufacturing of the cartridge disclosed in Patent Document 1, after separating the lid member from the housing portion, it is necessary to separate the absorber from the housing portion. However, since the absorber is fitted in the housing portion or the liquid is fixed, it is not easy to separate the absorber from the housing portion. Further, even when the absorber is not fitted in the housing portion, a step of separating the absorber from the housing portion must be performed separately from the step of separating the lid member from the housing portion, which may increase the tact time.

[0006] In view of the above problems, an object of the present invention is to provide a cartridge in which an absorber can be easily separated from a housing portion and the risk of an increase in tact time is suppressed, and a method for remanufacturing the same.

Means for Solving the Problems

[0007] In order to solve the above problems, a cartridge of the present invention is a cartridge having an absorber for holding a liquid, a housing portion having an opening and housing the absorber therein, and a lid member joined to the opening, wherein the lid member has a protrusion, and the protrusion is inserted into the absorber.

Effects of the Invention

[0008] According to the present invention, it is possible to provide a cartridge in which an absorber can be easily separated from a housing portion and the risk of an increase in tact time is suppressed, and a method for remanufacturing the same.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following embodiments do not limit the matters of the present invention, and not all combinations of the features described in the present embodiments are essential for the solution means of the present invention. The same reference numerals are assigned to the same components.

[0011] (First Embodiment) (Inkjet Recording Apparatus) FIG. 1 shows a schematic diagram of a liquid ejection device according to the first embodiment. The liquid ejection device according to the first embodiment is an inkjet recording apparatus, but is not limited thereto as long as it is a device that ejects liquid. The inkjet recording apparatus 10 (hereinafter also referred to as a recording apparatus) is an on-carriage type of serial recording method and includes a cartridge 100 and a carriage 11. The cartridge 100 is mounted on the carriage 11. In the recording apparatus 10, the carriage 11 reciprocates, the recording paper 12 is conveyed by a predetermined amount in a direction orthogonal to the reciprocating movement of the carriage, and the cartridge ejects ink onto the recording paper 12, thereby forming an image on the recording paper 12.

[0012] (Cartridge Overview) FIG. 2 shows a perspective view of a cartridge according to the first embodiment, and FIG. 3 shows an exploded perspective view of the cartridge according to the first embodiment. The cartridge 100 is of a type that stores ink for one color, and is generally a cartridge for black ink. Although the present disclosure is also applicable to a type that stores ink of a plurality of colors, generally a cartridge for color ink (cyan, magenta, yellow), in this embodiment, a cartridge for black ink will be used for explanation.

[0013] As shown in FIG. 3, the cartridge 100 includes a recording head (liquid ejection head) 110 that ejects ink, an absorber 130 that holds liquid, a housing portion 120 that houses the absorber 130 and the liquid, and a lid member 150 that joins with an opening 122 of the housing portion 120. Further, the cartridge 100 preferably includes a partition member 140 disposed between the absorber 130 and the lid member 150, and a filter 160 that removes foreign matter in the housing portion 120.

[0014] The recording head 110 is disposed on the bottom surface vertically below the housing portion 120, has a discharge element substrate that discharges liquid, and discharges ink based on discharge data. The absorber 130 is composed of a fibrous body, a porous body, etc., and can hold ink inside by capillary force. The absorber 130 is preferably housed in an absorber housing chamber 121 of the housing portion 120 so as to contact a filter 160 for removing foreign matter.

[0015] The lid member 150 is disposed so as to close the opening of the housing portion 120, and together with the housing portion 120, partitions the absorber housing chamber 121. The partition member 140 is located between the absorber 130 and the lid member 150, and holds the absorber 130 while fixing it. Details of the lid member 150 and the partition member 140 will be described later.

[0016] (Assembly process) FIG. 4 is a schematic cross-sectional view of the lid member 150 and the partition member 140 according to the first embodiment. FIG. 4(a) shows the state before the lid member 150 and the partition member 140 are assembled. As shown in FIG. 4(a), the lid member 150 defines a plane in the XY plane and has a first surface 152 and a second surface 154. The second surface 154 of the lid member 150 has a welding rib 195 and a protrusion 191 protruding in the positive Z-axis direction. In the first embodiment, the central axis of the protrusion 191 is perpendicular to the lid member 150, but may be inclined. The welding rib 195 may be an independent component and is disposed between the lid member 150 and the housing portion 120 when vibration welding is performed between the housing portion 120 and the lid member 150. Note that the negative Z-axis direction corresponds to the direction of gravity.

[0017] The partition member 140 defines a plane in the XY plane and defines a first surface 143 and a second surface 144. The partition member 140 has a through hole 164 penetrating in the Z-axis direction. The inner diameter of the through hole 164 is larger than the outer diameter of the protrusion 191. The partition member 140 has a dimension smaller than the region defined by the welding rib 195 in the XY plane. The second surface 144, which is the opposite surface of the first surface 143 of the partition member 140, has a rib portion 142 protruding in the Z-axis direction.

[0018] FIGS. 4(b) and (c) show the assembling process of the lid member 150 and the partition member 140. The assembling is performed in the order of FIG. 4(b) and FIG. 4(c). As shown in FIG. 4(b), the protrusion 191 of the lid member 150 is inserted into the through hole 164 of the partition member 140.

[0019] As shown in FIG. 4(c), the fixing portion 192 is formed by heating and melting the protruding portion 191 of the lid member 150. By melting the protruding portion 191, the outer diameter becomes larger than the inner diameter of the through hole 164, so that the protruding portion 191 catches at the position of the through hole 164, and the lid member 150 cannot come off with respect to the partition member 140. That is, the protruding portion 191 fixes the lid member 150 and the partition member 140 by the fixing portion 192 being positioned in the vicinity of the absorber side in the through hole 164. At this time, the fixing portion 192 is formed to be separable easily. Note that the protruding portion 191 is not limited to a cylindrical shape, and the through hole 164 is not limited to a circular shape.

[0020] FIGS. 4(d)-(e) show the joining process of the lid member 150 with the partition member 140 assembled thereto and the accommodating portion 120. FIG. 4(d) shows the state before joining the lid member 150 with the partition member 140 assembled thereto and the accommodating portion 120. As shown in FIG. 4(d), the tip portion 196 of the protruding portion 191 of the lid member 150 and the rib portion 142 of the partition member 140 project in the minus Z-axis direction. Further, the absorber 130 is inserted into the accommodating portion 120 in advance, and the absorber holds the liquid.

[0021] Next, as shown in FIG. 4(e), the lid member 150 assembled with the partition member 140 is brought into contact with the opening 122 of the housing portion 120, and the partition member 140 is inserted into the housing portion 120. The insertion of the partition member 140 is performed by arranging the lid member 150 with respect to the opening 122 of the housing portion 120 and bringing the welding rib 195 of the lid member 150 into contact with the opening 122 of the housing portion 120. At this time, the rib portion 142 of the partition member is pushed into the absorber 130, and a part of the protrusion 191 is inserted into the absorber 130. At this time, the relationship between the length A of the protrusion 191 and the distance B between the lid member 150 and the absorber 130 is set such that length A > distance B. By having such a relationship, a part of the protrusion 191 is inserted into the absorber 130. The longer the length A - distance B is, the longer the length that the protrusion 191 is inserted into the absorber 130 becomes, so that the separation process of the absorber 130 from the housing portion 120 described later can be facilitated. The protrusion 191 is preferably installed near the end in the direction opposite to the separation portion 159 of the lid member 150. The closer to the X direction from the rotation axis, the more likely the protrusion 191 catches on the absorber 130 in the X direction during separation, facilitating the separation of the absorber 130. However, the separation method is not limited to the above. Also, the tip portion 196 of the protrusion 191 is preferably in a sharp shape advantageous for insertion into the absorber 130. The protrusion 191 is roughened on the surface during molding or when forming the fixing portion 192, increasing the frictional force with the absorber 130 and facilitating separation when the absorber 130 is separated from the housing portion 120. Also, there may be a plurality of protrusions 191 and tip portions 196.

[0022] (Vibration Welding Process) FIG. 5 shows the vibration welding process of the lid member 150 assembled with the housing portion 120 and the partition member 140. First, as shown in FIG. 5(a), the lid member 150 is arranged with respect to the opening 122 of the housing portion 120, and the welding rib 195 of the lid member 150 is brought into contact with the opening 122 of the housing portion 120. Next, as shown in FIG. 5(b), the lid member 150 is vibrated while being pressed against the housing portion 120 with a predetermined pressure. The vibration direction of the lid member 150 is the X-axis direction of the lid member 150. The amplitude of the vibration is preferably in the range of 0.5 mm or more and 2.0 mm or less, and the frequency of the vibration is preferably in the range of 200 Hz or more and 400 Hz or less, but it is not limited to this. By vibrating the lid member 150 with respect to the housing portion 120, frictional heat is generated at the contact portion between the housing portion 120 and the welding rib 195, and the opening 122 of the housing portion 120 and the welding rib 195 are melted. Therefore, as shown in FIG. 5(c), the housing portion 120 and the lid member 150 are joined.

[0023] In this embodiment, vibration welding is adopted as the joining method between the lid member 150 and the housing portion 120. However, as long as the lid member 150 and the housing portion 120 can be joined, it is not limited to vibration welding.

[0024] (Remanufacturing of the Cartridge) FIG. 6 shows a flowchart of the remanufacturing of the cartridge 100. The step S801 in FIG. 6 represents the step of preparing a used cartridge 100. For example, after the cartridge 100 is circulated in the market, the used cartridge can be recovered and prepared.

[0025] Next, the process of S802 is to separate the lid member 150 from the opening 122 of the housing portion 120. Further, FIG. 7 shows the details of the process of separating the lid member 150 from the opening 122 of the housing portion 120. FIG. 7(a) shows a state in which the used above-described cartridge 100 is prepared. First, as shown in FIG. 7(b), the lid member 150 is moved relative to the housing portion 120 in the +Z-axis direction to separate the lid member 150. At this time, since the lid member 150 and the partition member 140 are hooked by the fixing portion 192, the partition member 140 also moves in the +Z-axis direction simultaneously with the separation of the lid member 150 from the housing portion 120. Further, since the tip portion 196 of the protrusion 191 of the lid member 150 is inserted into the absorber 130, the absorber 130 also moves in the +Z-axis direction with the separation of the lid member 150 from the housing portion 120. FIG. 7(c) shows a state in which the lid member 150 is further moved in the +Z-axis direction with respect to the housing portion 120. In this way, the housing portion 120 and the lid member 150 are completely separated, and along with the separation of the housing portion 120 and the lid member 150, the partition member 140 and the absorber 130 are also separated from the housing portion 120.

[0026] Next, in the process of S804, as shown in FIG. 7(d), the lid member 150 and the absorber 130 are separated by relatively moving the protrusion 191 and the tip portion 196 of the lid member 150 from the absorber 130 in the +Z-axis direction. Finally, as shown in FIG. 7(e), the lid member 150 and the partition member 140 are separated by applying stress to the fixing portion 192. As described above, it is preferable that the fixing portion 192 fixes the lid member 150 and the partition member 140 to such an extent that they can be easily separated.

[0027] As described above, since a part of the protrusion 191 of the lid member 150 is inserted into the absorber 130, even when the absorber 130 is fitted into the housing portion 120 or the liquid is fixed to the absorber 130, the absorber 130 can be easily separated from the housing portion 120. Furthermore, since the absorber 130 can be separated from the housing portion 120 along with the separation of the lid member 150 from the housing portion 120, an increase in tact time can be suppressed.

[0028] Next, in step S805, the interior of the housing portion 120 is cleaned to remove dirt such as ink. Next, in step S806, a new absorber (also referred to as the second absorber) is housed inside the housing portion 120. Next, in step S807, new ink is injected into the housing portion 120 to hold the ink in the second absorber. Next, in step S808, the cartridge 100 is remanufactured by joining a new lid member (the second lid member) to the opening 122 of the housing portion 120 (S809). The joining step of the second lid member can be performed in the same manner as the joining of the lid member 150 to the opening 122 of the housing portion 120.

[0029] In addition, in the absorber insertion step S805, as S805A, the absorber 130 separated in S804 and cleaned may be inserted into the housing portion 120. In the absorber cleaning step S805A, not only is the cleaning liquid infiltrated from one direction and suction-discharged, but the absorber 130 is completely immersed in the cleaning liquid, and the cleaning liquid is allowed to permeate to every corner for cleaning. Also, since the absorber 130 can be pressed and deformed in the cleaning liquid for cleaning, the remaining ink can be removed neatly.

[0030] In addition, before step S807, it is preferable to fix the second lid member and the partition member 140 by thermal caulking. Thereby, the handleability in subsequent steps can be improved. Also, since the partition member 140 is not joined to the housing portion 120, it is preferable to reuse it. By reusing the partition member 140, it becomes possible to improve the weight remanufactured product rate of the cartridge 100, and the cartridge 100 can be made more environmentally friendly.

[0031] In addition, once the lid member 150 is joined to the housing portion 120, even if the lid member 150 is separated from the housing portion 120, the welding ribs 195 are thinned. Therefore, in the remanufacture of the cartridge 100, it is preferable to use a new lid member (the second lid member).

[0032] Here, in the present embodiment, the shape of the partition member 140 is an elongated shape, and the aspect ratio, which is the ratio of the length to the width in the partition member 140, can be 1:4, preferably the short side dimension is 15.2 mm and the long side dimension is 64 mm. The cartridge 100 of the present disclosure does not have to be of the head-integrated type.

[0033] The structures, fixing methods, separation methods, and remanufacturing methods of the lid member 150 and the partition member 140 in the embodiments of the present disclosure can be adapted to accommodation portions 120 of any shape. As an example, the structures, fixing methods, separation methods, and remanufacturing methods of the present disclosure can be adapted to a cartridge configured such that the accommodation portion 120 has a plurality of absorber accommodation chambers as shown in FIG. 8(a). FIG. 8(b) is a schematic cross-sectional view showing the lid member 150 and the partition member 140 of the cartridge according to the present invention assembled to the accommodation portion 120. As shown in FIG. 8(b), the cartridge may be configured such that a plurality of absorber accommodation chambers are arranged in the longitudinal direction of the cartridge. Even when a plurality of absorbers are accommodated in the plurality of absorber accommodation chambers, the plurality of protrusions 191 of the lid member 150 are inserted into the respective absorbers, so that the plurality of absorbers 130 can be taken out as the lid member 150 is separated from the accommodation portion 120. In the prior art, the more absorbers a cartridge has, the more problematic the absorber separation process becomes. Therefore, the configuration of the present embodiment is suitable for a cartridge that accommodates a plurality of absorbers 130. Further, the structures, fixing methods, separation methods, and remanufacturing methods of the present disclosure are also applicable to a configuration in which the accommodation portion 120 is divided into three by a T-shaped wall along the Z-axis direction and the absorber is arranged in a part of the absorber accommodation chamber as shown in FIG. 8(c).

[0034] As described above, according to the present invention, it is possible to provide a cartridge 100 and a remanufacturing method thereof in which the absorber 130 can be easily separated from the accommodation portion 120 and the risk of an increase in tact time is suppressed.

[0035] (Second Embodiment) The configuration of the cartridge 100 in the second embodiment of the present invention will be described. In the following description, only the parts different from the first embodiment will be mainly described, and the description of the parts similar to the first embodiment will be omitted.

[0036] FIG. 9 is a cross-sectional view of the cartridge 100 according to the second embodiment. This embodiment is different from the first embodiment in that the tip 196 of the rib portion (protrusion portion) 142 of the partition member 140 is inserted into the absorber 130, rather than the protrusion 191 of the lid member 150 being inserted into the absorber 130. Since the lid member 150 and the partition member 140 are assembled at the fixing portion 192, as the lid member is separated from the accommodating portion 120, the partition member 140 is separated from the accommodating portion, and thus the absorber 130 into which the protrusion (tip 196) of the partition member 140 is inserted is also separated from the accommodating portion. The location with the protrusion (tip 196) may be other than the rib portion 142. The assembling method of the fixing portion 192 is the same as that of the first embodiment.

[0037] Further, when the cartridge 100 has a plurality of absorbers 130, it is preferable that the partition member 140 has a plurality of protrusions (tips 196), and the protrusions (tips 196) are inserted into the respective absorbers 130.

[0038] Also, the remanufacturing method of the cartridge 100 according to the second embodiment is the same as that of the first embodiment.

[0039] As described above, even when the protrusion is formed on the partition member, it is possible to provide a cartridge and a remanufacturing method thereof in which the absorber can be easily separated from the accommodating portion and the risk of an increase in tact time is suppressed.

[0040] (Third Embodiment) FIG. 10 shows a cartridge 100 according to the third embodiment. In the third embodiment, it is different from the first embodiment in that it does not have a partition member 140. Even when the partition member 140 is not provided, the tip 196 of the protrusion 191 of the lid member 150 is inserted into the absorber 130. As a result, when the lid member 150 is separated from the housing portion 120, the absorber 130 is separated from the housing portion 120. In the third embodiment, since the partition member 140 is not provided, it is preferable that the rigidity of the protrusion 191 is high so that the protrusion 191 can press the absorber 130. As a method for increasing the rigidity of the protrusion 191, increasing the diameter of the protrusion 191 can be mentioned. In addition, in the third embodiment, since the partition member 140 is not provided, the fixing portion 192 is not formed.

[0041] Also, the method for remanufacturing the cartridge 100 according to the third embodiment is the same as that of the first embodiment.

[0042] From the above, even when there is no partition member, if the protrusion of the lid member is inserted into the absorber, the absorber can be easily separated from the housing portion, and a cartridge and a method for remanufacturing the same that can suppress the risk of an increase in tact time can be provided.

[0043] (Fourth Embodiment) FIG. 11 shows a cartridge 100 according to a fourth embodiment. The cartridge 100 according to the fourth embodiment is different from the first embodiment in that it does not have a partition member 140 and a rib portion 142 is provided on the lid member 150. That is, since the lid member 150 presses the absorber 130, it is different from the first embodiment in that it also has the function of the partition member 140. In other words, it is different from the first embodiment in that the lid member and the partition member are integrally formed. Even in such a configuration, since the lid member 150 has a protrusion 191 and its tip 196 is inserted into the absorber 130, the absorber 130 can be separated from the housing portion 120 as the lid member 150 is separated from the housing portion 120. In the present embodiment, since it is not necessary to provide the partition member 140 separately from the lid member 150, it is not necessary to assemble the partition member 140 and the lid member 150, so that an increase in tact time can be further suppressed.

[0044] Also, in FIG. 11, the protrusion 191 is formed at a location other than the rib portion 142 of the lid member 150. However, as shown in FIG. 12, the protrusion (tip portion 196) may be formed on the rib portion 142.

[0045] Also, the method for remanufacturing the cartridge 100 according to the fourth embodiment is the same as that of the first embodiment.

[0046] As described above, even when the lid member has the function of the partition member, if the protrusion of the lid member is inserted into the absorber, the absorber can be easily separated from the housing portion, and a cartridge and a method for remanufacturing the same that can suppress the risk of an increase in tact time can be provided.

[0047] (Fifth Embodiment) FIG. 13 shows a cartridge 100 according to the fifth embodiment. The cartridge 100 according to the fifth embodiment is different from the first embodiment in that a claw portion 197 extending toward the lid member side is formed at the tip portion 196 of the protrusion 191 inserted inside the absorber 130. By forming the claw portion 197, when the absorber 130 is separated from the housing portion 120 as the lid member 150 is separated from the housing portion 120, the claw portion 197 catches on the absorber 130, making it easier to separate the absorber 130 from the housing portion 120.

[0048] FIG. 14 shows a method of forming the claw portion 197. FIG. 14(a) shows a state before forming the claw portion 197 on the lid member 150 using the mold member 200. A space is formed in the mold member 200 according to the shape of the claw portion to be formed. FIG. 14(b) shows the step of bringing the mold member 200 into contact with the tip portion 196 of the protrusion 191 of the lid member 150. The mold member 200 is a member having a melting point higher than that of the tip portion 196. Next, FIG. 14(c) shows the step of melting the tip portion 196 by heating the tip portion 196. At this time, in order to support the tip portion 196 that melts, the tip portion 196 deforms into a shape similar to the space formed in the mold member 200. Finally, FIG. 14(d) shows the step of separating the mold member 200 after the temperature of the tip portion 196 has dropped, that is, after the tip portion 196 has cooled and solidified. Through the above steps, the claw portion 197 is formed at the tip portion 196.

[0049] Also, the method of remanufacturing the cartridge 100 according to the fifth embodiment is the same as that of the first embodiment.

[0050] As described above, by forming a claw portion at the portion inserted inside the absorber, the absorber can be more easily separated from the housing portion, and a cartridge and its remanufacturing method that can suppress the risk of an increase in tact time can be provided.

[0051] (Sixth Embodiment) FIG. 15 shows a cartridge 100 according to the sixth embodiment. In the cartridge 100 according to the sixth embodiment, an uneven portion 198 is formed at the tip portion 196 of a protrusion 191 inserted inside an absorber 130. By forming the uneven portion 198, the contact area between the uneven portion 198 and the absorber 130 increases, and the frictional force acts strongly. Therefore, as the lid member 150 is separated from the housing portion 120, the absorber 130 can be easily separated from the housing portion 120.

[0052] FIG. 16 shows a method of forming the uneven portion 198. FIG. 16(a) shows a state before forming the uneven portion 198 on the protrusion 191 of the lid member 150 using a mold member 201. A space is formed in the mold member 201 according to the shape of the uneven portion to be formed. FIG. 16(b) shows a step of bringing the mold member 201 into contact with the tip portion 196 of the protrusion 191 of the lid member 150. The mold member 201 is a member having a melting point higher than that of the tip portion 196. Next, FIG. 16(c) shows a step of melting the tip portion 196 by heating the tip portion 196. At this time, in order to support the tip portion 196 that melts, the tip portion 196 is deformed into a shape similar to the space formed in the mold member 201. Finally, FIG. 16(d) shows a step of separating the mold member 201 after the temperature of the tip portion 196 has dropped, that is, after the tip portion 196 has cooled and solidified. Through the above steps, the uneven portion 198 is formed at the tip portion 196.

[0053] Also, the method of remanufacturing the cartridge 100 according to the sixth embodiment is the same as that of the first embodiment.

[0054] As described above, by forming the uneven portion at the portion inserted inside the absorber, the absorber can be more easily separated from the housing portion, and it is possible to provide a cartridge and a method for remanufacturing the same that suppress the risk of an increase in tact time. Therefore, since the remanufacturing of the cartridge is promoted by the present disclosure, the technology described in this specification can contribute to the realization of a sustainable society such as a decarbonized / circular society.
