[0009] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.
[0010] <First embodiment> (Inkjet recording device overview) 1 is a schematic diagram of an inkjet recording device according to a first embodiment. The inkjet recording device 10 (hereinafter also referred to as the recording device) is an on-carriage type that uses a serial recording method, and includes a cartridge 100 and a carriage 11. The cartridge 100 is mounted on the carriage 11. In the recording device 10, the carriage 11 moves back and forth, and the recording paper 12 is transported a predetermined amount at a time in a direction perpendicular 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.
[0011] (Cartridge Overview) Fig. 2 shows a perspective view of the 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 a type that contains ink of one color, and is generally a cartridge for black ink. The present disclosure is also applicable to a type that contains ink of multiple colors, and generally a cartridge for color inks (cyan, magenta, and yellow), but in this embodiment, a cartridge for black ink is used.
[0012] As shown in FIG. 3, the cartridge 100 includes a recording head 110 that ejects ink, a tank 120 that stores ink, an absorber 130 that absorbs and holds liquid, a partition member 140 that presses the absorber 130, and a cover member 150 that is joined to the tank 120. The cartridge 100 includes a filter 160 that removes foreign matter from the tank 120. The recording head 110 is configured to eject ink based on ejection data, and is disposed on the bottom surface below the tank 120 in the vertical direction. The absorber 130 is made of a fibrous body, a porous body, or the like, and can hold ink inside by exerting a capillary force. The absorber 130 is accommodated in an absorber accommodation chamber 121 of the tank 120 so as to abut against a filter 160 for removing foreign matter.
[0013] The lid member 150 is disposed so as to close the opening of the tank 120, and together with the tank 120, defines an absorbent housing chamber 121. The partition member 140 is positioned between the absorbent body 130 and the lid member 150, and holds and fixes the absorbent body 130. The lid member 150 and the partition member 140 will be described in detail later.
[0014] (Assembly process) FIG. 4 is a schematic cross-sectional view of the lid member 150 and the partition member 140 of the cartridge 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 defines a first surface 152 and a second surface 154. The second surface 154 of the lid member 150 has a welding rib 195 and protrusions 20, 22 protruding in the positive Z-axis direction. The lid member 150 is formed of a thermally expandable material. In the first embodiment, the protrusions 20, 22 are spaced apart from each other by a distance A along the X-axis. The welding rib 195 may be an independent part and is disposed between the lid member 150 and the tank 120 when vibration welding is performed. The negative Z-axis direction corresponds to the direction of gravity.
[0015] The partition member 140 defines a plane in the XY plane, defines a first surface 143 and a second surface 144, and has a dimension B along the X-axis. The second surface 144, which is the surface opposite to the first surface 143 of the partition member 140, has a rib portion 142 protruding in the negative Z-axis direction. In FIG. 4(a), the cover member 150 is at room temperature and has not thermally expanded. Since the distance A between the protrusions 20, 22 is smaller than the dimension B of the partition member 140, the partition member is not inserted between the protrusions 20, 22.
[0016] Figures 4(b)-(d) show the process of assembling the lid portion 150 and the partition member 140. The assembly is performed in the order of Figures 4(b), 4(c), and 4(d). As shown in Figure 4(b), a heat source 25 is brought into contact with or adjacent to the lid member 150, and the lid member 150 is heated. The lid member 150 is thermally expanded, and the distance A between the protrusions 20, 22 is enlarged. When the lid member 150 is thermally expanded, the distance A between the protrusions 20, 22 is greater than the dimension B of the partition member.
[0017] As shown in Fig. 4(c), because the distance A between the protrusions 20, 22 is greater than the dimension B of the partition member 140, the partition member 140 is inserted between the protrusions 20, 22 and the partition member 140 is disposed between the protrusions 20, 22. As shown in Fig. 4(d), the heat source 25 is moved away from the cover member 150 and the temperature of the cover member 150 decreases. The cover member 150 does not thermally expand and the distance A between the protrusions 20, 22 is reduced. The partition member 140 is gripped by the protrusions 20, 22 and the cover member 150 and the partition member 140 are fixed.
[0018] (Vibration welding process) 5 shows a vibration welding process of the lid member 150 fixed to the tank 120 and the partition member 140. The lid member 150 is placed relative to the opening of the tank 120, the welding rib 195 of the lid member 150 is brought into contact with the opening of the tank 120, and the lid member 150 is vibrated while being pressed against the tank 120 with a predetermined pressure. The vibration direction of the lid member 150 is the X-axis direction of the lid member 150. The vibration amplitude is in the range of 0.5 mm to 2.0 mm, and the vibration frequency is in the range of 200 Hz to 400 Hz. The lid member 150 is vibrated relative to the tank 120 to generate frictional heat at the contact point between the tank 120 and the welding rib 195, and the opening of the tank 120 and the welding rib 195 are melted, thereby joining the tank 120 and the lid member 150.
[0019] (separation process) The used cartridge 100 can be collected by a collection company or the like. The cartridge 100 is washed to remove stains such as ink, and undergoes multiple quality inspections. The tank 120 and the lid member 150 of the cartridge 100 that is determined to be reusable are separated, and the partition member 140 can be reused.
[0020] FIG. 6 shows the process of separating the lid member 150 and the partition member 140. FIG. 6(a) shows the state before the separation of the lid member 150 and the partition member 140. The lid member 150 is at room temperature and does not thermally expand, and the protrusions 20 and 22 hold the partition member 140, so the lid member 150 and the partition member 140 are not separated. FIG. 6(b)-(c) show the process of separating the lid portion 150 and the partition member 140. Separation is performed in the order of FIG. 6(b) and FIG. 6(c). As shown in FIG. 6(b), the lid member 150 is heated by the heat source 25. The lid member 150 is heated and thermally expands, and the interval A between the protrusions 20 and 22 is enlarged. At this time, the interval A between the protrusions 20 and 22 is greater than the dimension B of the partition member 140. 6(c), the protrusions 20, 22 do not grip the partition member 140, and the lid member 150 and the partition member 140 are separated. After separation, the heat source 25 is moved away from the lid member 150, whereby the lid member 150 cools and returns to its original shape.
[0021] (How to reuse) The separated partition member 140 is reused to be incorporated into the next product. A method for reusing the partition member 140 includes a step of peeling off the cover member 150 from the tank 120, a step of separating the cover member 150 and the partition member 140, a step of replacing the absorbent body 130, and a step of cleaning the inside of the tank 120. A method for reusing the partition member 140 includes a step of inserting a new absorbent body 130 into the tank 120 and injecting liquid, a step of fitting a new cover member 150 and the partition member 140, and a step of welding the newly prepared cover member 150 and the tank 120. In this manner, the cartridge is manufactured and reused. The number of the protrusions 20, 22 is not limited to two, and may be one or three or more.
[0022] The amount of displacement due to thermal expansion is calculated by the linear expansion coefficient x the amount of temperature change x the length in the direction of thermal expansion. For this reason, the partition member 140 uses a material with a linear expansion coefficient lower than that of the cover member 150, or a material with a low thermal conductivity. The partition member 140 is formed into a shape such that, at room temperature, the distance A between the protrusions 20, 22 is less than the dimension B of the partition member 140, and, in a heated state, the distance A between the protrusions 20, 22 is greater than the dimension B of the partition member 140. This facilitates assembly and disassembly of the cover member 150 and the partition member 140, improving recyclability.
[0023] <Modification of the first embodiment> Fig. 7 shows a cover member 150 and a partition member 140 according to a modification of the first embodiment. As shown in Fig. 7, a first surface 143 of the partition member 140 has protrusions 20 and 22, which are spaced apart from each other by a distance A along the X-axis. A second surface 154 of the cover member 150 has a gripped portion 31, which has a dimension B along the X-axis. In this case, it is desirable for the cover member 150 to use a material having a lower linear expansion coefficient or a lower thermal conductivity than the partition member 140.
[0024] In a modified example of the first embodiment, the partition member 140 is heated in a manner similar to that of the first embodiment, the distance A between the protrusions 20, 22 is enlarged, the gripped portion 31 of the lid member 150 is gripped by the protrusions 20, 22, and the lid member 150 and the partition member 140 are fixed.
[0025] <Second embodiment> 8 shows the cover member 150 and the partition member 140 in the second embodiment. In the second embodiment, the protrusions 20, 22 have side portions 26, 28, respectively, which face each other along the X-axis. When the cover member 150 and the partition member 140 are assembled, the side portions 26, 28 fix the partition member 140 in the Z direction.
[0026] In the second embodiment, the lid member 150 is heated in the same manner as in the first embodiment, the interval A between the protrusions 20, 22 is enlarged, and the partition member 140 is gripped by the protrusions 20, 22 and the side portions 26, 28, and the lid member 150 and the partition member 140 are fixed. This configuration can prevent the lid member 150 and the partition member 140 from falling off during transportation on the device, etc.
[0027] <Third embodiment> Fig. 9 shows the cover member 150 and the partition member 140 in the third embodiment. In the third embodiment, as shown in Fig. 9, the first surface 143 of the partition member 140 has protrusions 60, 62. The protrusions 60, 62 define the contact reduction slits 27, and the contact reduction slits 27 reduce the contact area between the cover member 150 and the partition member 140 on the surface of the partition member 140 facing the cover member 150. The rib portion 142 has a heat dissipation slit 28 provided in the Z-axis direction.
[0028] When heat is applied to the cover member 150 to cause thermal expansion, the contact-reducing slits 27 reduce the contact area between the cover member 150 and the partition member 140, suppressing heating of the partition member 140. In addition, the heat-dissipating slits 28 dissipate heat from the partition member 140 to the atmosphere, suppressing a rise in temperature of the partition member 140. The contact-reducing slits 27 and the heat-dissipating slits 28 suppress thermal expansion of the partition member 140, facilitating assembly and disassembly of the cover member 150 and the partition member 140. Alternatively, the protrusions 60, 62 may be provided on the second surface 154 of the cover member 150.
[0029] <Fourth embodiment> FIG. 10 shows the cover member 150 and the partition member 140 in the fourth embodiment. As shown in FIG. 10(a), in the fourth embodiment, the protrusions 20, 22 are inclined with respect to the second surface 154 of the cover member 150 and are spaced apart from each other in a fan-like manner as they extend in the negative Z direction. The proximal portions of the protrusions 20, 22 with respect to the second surface 154 have grooves 32, 34, respectively, and the grooves 32, 34 face each other. The protrusions 20, 22 have gripping portions 24, 26 that protrude in the negative Z direction. The gripping portions 24, 26 define an interval A along the X-axis between the gripping portions 24, 26. Alternatively, at least one of the protrusions 20, 22 may have a groove.
[0030] In the fourth embodiment, partition member 140 has a dimension B along the X-axis. The sides of partition member 140 along the Y-direction have gripped portions 145, 147 extending in the Z-direction. The distance A between gripping portions 24, 26 is smaller than the dimension B of partition member 140.
[0031] 10(b), partition member 140 is press-fitted between gripping portions 24, 26 of lid member 150, and gripping portions 24, 26 and gripped portions 145, 147 engage with each other to fix lid member 150 and partition member 140. With this configuration, assembly is possible without using welding or adhesive.
[0032] Figure 11 shows the process of assembling the cover member 150 to which the partition member 140 is fixed and the tank 120 in the fourth embodiment. Figure 11(a) shows the state before the cover member 150 and the tank 120 are assembled. Figures 11(b)-(e) show the process of assembling the cover member 150 and the tank 120. The assembly is performed in the order of Figures 11(b), 11(c), 11(d), and 11(e).
[0033] As shown in FIG. 11(b), the cover member 150 is placed at the opening of the tank 120, and the rib portion 142 of the partition member 140 comes into contact with the absorber 130. As shown in FIG. 11(c), when the partition member 140 is further pushed into the tank 120, the partition member 140 is pushed up by the absorber 130, and stress in the positive Z-axis direction is applied to the protrusions 20, 22 and the gripping portions 24, 26. This generates concentrated stress in the grooves 32, 34 of the protrusions 20, 22, and the protrusions 20, 22 are destroyed starting from the grooves 32, 34. As shown in FIG. 11(d), vibration welding of the cover member 150 and the tank 120 is performed along the direction S.
[0034] 11(e), the lid member 150 and the tank 120 are fixed, and the partition member 140 and the lid member 150 are not fixed within the tank 120. The partition member 140 is held within the tank 120 by the lid member 150 and the absorber 130, so even if the convex parts 20, 22 are destroyed, there is no hindrance to pressing down the absorber 130. By destroying the convex parts 20, 22, when the lid member 150 and the tank 120 are removed, the lid member 150 and the partition member 140 are already separated, making it easy to disassemble the two parts.
[0035] Used cartridges 100 can be collected by collection companies or the like. Cartridges 100 are washed to remove stains such as ink, and undergo multiple quality inspections. The tank 120 and lid member 150 of cartridges 100 that are determined to be reusable are separated, and the partition member 140 can be reused. With the configuration of the fourth embodiment, when the lid member 150 and tank 120 are separated, the partition member 140 has already been separated from the lid member 150, so that the process of disassembling the lid member 150 and the partition member 140 can be eliminated.
[0036] <Fifth embodiment> Fig. 12 shows a lid member 150 and a partition member 140 in the fifth embodiment. As shown in Fig. 12(a), the protrusions 20, 22 extend in the negative Z direction from the second surface 154 of the lid member 150. Proximal portions of the protrusions 20, 22 relative to the second surface 154 have grooves 36, 38 surrounding the protrusions 20, 22, respectively. Distal portions of the protrusions 20, 22 relative to the second surface 154 have gripping portions 28, 29.
[0037] The gripping portion 28 has a first portion 281 extending in a direction away from the center of gravity of the lid member 150 along the X direction, and a second portion 282 extending in the negative Z direction from a distal portion of the first portion 281. The gripping portion 29 has a first portion 291 extending in a direction away from the center of gravity of the lid member 150 along the X direction, and a second portion 292 extending in the negative Z direction from a distal portion of the first portion 291. The second portions 282, 292 define a distance A along the X axis.
[0038] In the fifth embodiment, the bulkhead member 140 has a dimension B along the X-axis. The sides of the bulkhead member 140 along the Y-direction have gripped portions 145, 147 extending in the Z-direction. The distance A between the second portions 282, 292 is smaller than the dimension B of the bulkhead member 140.
[0039] 12(b), the partition member 140 is press-fitted between the gripping portions 28, 29 of the cover member 150, and the second portions 282, 292 of the gripping portions 28, 29 and the gripped portions 145, 147 engage with each other, thereby fixing the cover member 150 and the partition member 140. In addition, the first portions 281, 291 suppress movement of the partition member in the positive Z-axis direction. This configuration allows for low-cost assembly without the use of welding or adhesive.
[0040] FIG. 13 shows the assembly process of the cover member 150 and the tank 120 to which the partition member 140 is fixed in the fifth embodiment. FIG. 13(a) shows the state before the cover member 150 and the tank 120 are assembled. FIG. 13(b)-(d) show the assembly process of the cover member 150 and the tank 120. The assembly is performed in the order of FIG. 13(b), FIG. 13(c), and FIG. 13(d). As shown in FIG. 13(b), the cover member 150 is placed at the opening of the tank 120, and the rib portion 142 of the partition member 140 contacts the absorber 130. As shown in FIG. 13(c), when the cover member 150 and the tank 120 are vibration-welded along the direction S, stress concentration occurs in the grooves 36, 38 surrounding the protrusions 20, 22, and the protrusions 20, 22 are destroyed starting from the grooves 36, 38. As shown in FIG. 13(d), the cover member 150 and the tank 120 are fixed, and the partition member 140 and the cover member 150 within the tank 120 are not fixed.
[0041] Since the partition member 140 is held by the lid member 150 and the absorber 130 inside the tank 120, even if the protrusions 20, 22 are destroyed, there is no hindrance to pressing down the absorber 130. By destroying the protrusions 20, 22, when the lid member 150 and the tank 120 are removed, the lid member 150 and the partition member 140 are already separated, facilitating disassembly of the two parts. The lid member may be made of a material capable of shrinking when cured by ultraviolet light.
[0042] With the configuration of the fifth embodiment, when the cover member 150 and the tank 120 are separated, the partition member 140 has already been separated from the cover member 150, so that the process of disassembling the cover member 150 and the partition member 140 can be omitted.
[0043] Although it was explained in the first embodiment, the method of reuse will be explained again. The partition member 140 is separated and reused to be incorporated into the next product. The method of reusing the partition member 140 includes a step of peeling off the cover member 150 from the tank 120, a step of separating the cover member 150 and the partition member 140, a step of replacing the absorbent body 130, and a step of cleaning the inside of the tank 120. The method of reusing the partition member 140 includes a step of inserting a new absorbent body 130 into the tank 120 and injecting liquid, a step of fitting the new cover member 150 and the partition member 140 together, and a step of welding the new cover member 150 and the tank 120 together. The cartridge is manufactured and reused by such a method.
[0044] In any embodiment, the shape of the partition member 140 is elongated, and the aspect ratio (here, the ratio of length to width) of the partition member 140 may be 1:4, and preferably the short dimension is 15.2 mm and the long dimension is 64 mm. The cartridge 100 of the present disclosure does not need to be a head-integrated type. (Reuse method of the first embodiment) The cartridge reuse method of this embodiment according to the present disclosure will be described with reference to Fig. 14. The cartridge reuse process of this embodiment ranges from a lid member peeling step S802 for peeling the lid member 150 from the cartridge 100 to a lid member welding step for welding the lid member 150, so these steps will be described in detail. Fig. 10 shows an excerpt from the lid member peeling step to the lid member welding step in the cartridge reuse process flow.
[0045] The cartridge reuse process starts with a step S801 of preparing a used cartridge 100. Next, after checking the appearance of the cartridge and cleaning the appearance, the process enters a step S802 of peeling off the cover member 150. In this step, the cover member 150 is moved relatively to the tank 120 to peel off the cover member 150. Then, the process proceeds to a step S803 of separating the cover member 150 and the partition member 140. In the separation step S803, the cover member 150 and the partition member 140 are separated from each other since the cover member 150 and the partition member 140 are integrated by crimping. As described above, the fixation by this crimping is performed to an extent that they can be easily separated. Therefore, the partition member 140 can be separated by relatively peeling it off from the cover member 150. The separated cover member 150 is discarded, and the partition member 140 is reused. Then, the process proceeds to a step S804 of removing the absorber, in which the absorber 130 that has run out of ink is removed from the tank 120. Then, the tank cleaning step S805 is performed. In the tank cleaning step S805, the inside of the tank 120 is cleaned. Then, the process proceeds to the absorbent inserting step S806. In the absorbent inserting step S806, the absorbent 130 removed in the absorbent removing step S804 may be inserted into the tank 120 as a cleaned absorbent (S806A). Also, in the absorbent inserting step S806, a new absorbent may be inserted into the tank. In the absorbent cleaning step S806A, the cleaning liquid is not only permeated from one direction and sucked and discharged, but also the absorbent 130 is immersed in the cleaning liquid entirely and cleaned by permeating every corner with the cleaning liquid. Also, the absorbent 130 can be cleaned by pressing and deforming it in the cleaning liquid, so that the remaining ink can be neatly removed. After the absorbent inserting step S806, the ink injection step S807 is performed, and ink is injected into the tank 120 while being soaked into the absorbent 130 with an injection needle or the like. Then, the lid member welding step S808 is performed, but before that, as described above, a step S808A is performed to thermally crimp the lid member 150 and the partition member 140 to improve handling. In the crimping step S808A, a new lid member 150 is used, and the partition member 140 separated in the separation step S803 is used for the thermal crimping. The thermal crimping in this step is also performed to a degree that allows for easy peeling by hand, taking into consideration future reuse.The integrated lid member 150 and partition member 140 are placed on top of the absorbent body, and a lid member welding step S808 is performed. Since the lid member 150 is new, welding can be performed while ensuring airtightness. Subsequent steps include recording inspection and packaging, and the reusable cartridge is completed S809.
[0046] In the case of the black ink cartridge of this embodiment described above, the weight of the lid member 150 is about 13% of the total weight of the cartridge excluding ink, and the weight of the partition member 140 is about 11%. If the lid member 150 is discarded and the partition member 140 is reused, the recycling rate is about 87%. In the case of a comparative example type lid in which the lid member 150 and the partition member 140 are integrated, the weight of the lid is about 19%, so if the lid is discarded, the recycling rate is 81%. Since the lid member 150 is a substantially flat plate-shaped part, the weight of the part that must be discarded can be minimized, making it possible to improve the recycling rate compared to the comparative example lid.
[0047] The structure, fixing method, separation method, and reuse method of the cover member 150 and the partition member 140 in the embodiment of the present disclosure can be applied to the tank 120 of any shape. For example, the structure, fixing method, separation method, and reuse method of the present disclosure can be applied to a cartridge having a configuration in which the tank 120 has a plurality of absorbent storage chambers as shown in FIG. 15(a). In addition, the structure, fixing method, separation method, and reuse method of the present disclosure can also be applied to a configuration in which the tank 120 is divided into three by a T-shaped wall along the Z-axis direction and the absorbent is placed in a part of the absorbent storage chamber as shown in FIG. 15(b). The technology described in this specification can contribute to the realization of a sustainable society such as a carbon-free / recycling society.
