Description

  The present invention relates to a disassembling apparatus and a disassembling method for an ink cartridge used for an ink jet printer and containing ink.

  Recycling of ink cartridges used in ink jet printers has attracted attention from the viewpoint of environmental protection. For example, since the ink cartridge container constituting the ink cartridge is made of plastic, attention has been drawn to the fact that plastic recycling technology can be used.

  Here, when the ink cartridge container is regenerated, it is necessary to disassemble the used ink cartridge once. However, if the ink cartridge is cut using a cutting tool such as a circular saw, cutting waste is generated. For this reason, the recycling rate of the resin material constituting the ink cartridge container (the weight of reusable resin relative to the total weight of the resin constituting the ink cartridge container) was as low as about 70%.

  Patent Document 1 discloses an ink cartridge and a method for disassembling the ink cartridge, which are designed to be easily disassembled and to allow the disassembled components to be sorted by material. The ink cartridge disclosed in Patent Document 1 uses many recyclable resin parts. In the ink cartridge of Patent Document 1, the main body case, the lid case, the supply port film, and the vent film are made of a resin made of the same material for the purpose of facilitating sorting after disassembly. Further, in Patent Document 1, when cutting the cartridge case, in order not to cut the cartridge case and the ink absorbing material together, the gap on the lower surface of the lid case on which the rib is projected is cut horizontally with a sawing cutter. It has been shown.

  However, Patent Document 1 does not disclose specific means for disassembling a large amount of ink cartridges.

  An object of the present invention is to provide a disassembling apparatus and a disassembling method capable of disassembling a large amount of ink cartridges in a small space.

  The disassembling apparatus of the present invention has a plurality of turntables for transporting ink cartridges, and in the one turntable, a first disassembly process for removing at least a part of the ink cartridge including one surface is performed, At least one of the ink cartridges including a surface different from the one surface in the other turntable after the ink cartridge partially removed by the first disassembly process is transferred to the other turntable. A second dismantling process for removing a part is performed.

Further, the disassembly method of the present invention includes a first disassembly treatment step of removing at least a part of the ink cartridge including one surface in one turntable that conveys the ink cartridge;
A step of transferring the ink cartridge, a part of which has been removed by the first disassembly processing step, to another turntable;
A second disassembly treatment step of removing at least a part of the ink cartridge including a surface different from the one surface in the other turntable;
It is characterized by having.

  According to the present invention, since the ink cartridge is transported by the turntable, the installation space is less than that of the line type apparatus. Therefore, it is possible to disassemble a large amount of ink cartridges in a small space.

(First embodiment)
The label separation method according to the first embodiment of the present invention is a method in which a surface on which a label is affixed is cut by a cutting means among surfaces of a plastic ink cartridge container constituting an ink cartridge. The surface on which the label is attached is the same as the surface of the lid case of the ink cartridge container.

  The ink cartridge is a cartridge used in an ink jet printer, and ink of a predetermined color is accommodated inside the cartridge container. An inkjet printer is a printing technology that forms a desired image on a medium such as paper by selectively discharging ink droplets into a predetermined area using thermal printing, piezoelectric printing, or other inkjet printing technology. It is an apparatus for carrying out.

  Incidentally, a label is affixed to a predetermined surface of the cartridge case for the purpose of displaying the color and model number of the ink contained in the ink cartridge. The label contains a printing material such as ink. Here, even if the film constituting the label is the same material as the constituent material of the members such as the cartridge case, the label contains the printing substance together with the film. For this reason, if recycling (reuse) is performed with this label attached, the purity of the material itself is lowered. The printing substance contained in the label can be removed by, for example, reprecipitation of the resin, but it is necessary to use a substance that does not need to be used when the organic solvent is originally recycled. Will be.

  The above-described ink cartridge of Patent Document 1 also has a vent film having a display function as a label. In Patent Document 1, although this vent film is the same material (resin material) as the main body case and the lid case, since the vent film also includes a printing substance, the above-described printing substance. There seems to be a problem related to this.

  Further, in Patent Document 1, when the gap on the lower surface of the lid case is cut horizontally with a sawing cutter, the vent film is left on the lid case cut from the main body case without being peeled along the perforations. The film remains stuck. Thus, it is not appropriate to discard the lid case with the vent film attached as it is from the viewpoint of resource reuse. However, when the lid case with the vent film attached thereto is reused as a resource, if the lid case is thick, more resin material that is a recycled resource can be obtained. However, when the printing material used for display is included in the vent film, the purity of the resin material, which is a recycled resource, is low.

  On the other hand, since the label affixed to the cartridge case is small and welded to the cartridge case, mechanical peeling such as peeling by hand is difficult.

  The first embodiment of the present invention provides a label separation method for obtaining recycled resources obtained from an ink cartridge with high purity and high recovery rate.

  Hereinafter, the present embodiment will be described in detail with appropriate reference to the drawings.

FIG. 1 is a schematic diagram showing a first embodiment of the label separation method of the present invention. As shown in FIG. 1, the label separation method in the present embodiment specifically includes the steps (1a) to (1c) described below.
(1a) Step of fixing the ink cartridge (FIG. 1 (a))
(1b) Separating the label from the ink cartridge using the cutting means (with the ink cartridge fixed) (FIG. 1B)
(1c) Step of separating the ink cartridge from the cutting means (FIG. 1 (c))

  Hereinafter, each step will be described.

(1a) Step of fixing the ink cartridge (FIG. 1 (a))
The label separation method of the present invention is performed, for example, on the ink cartridge 10 to which the label 12 is attached as shown in FIG. Here, the ink cartridge 10 shown in FIG. 1A includes an ink storage container that stores ink, a metal portion, a plastic portion other than the ink storage container, and the like. In FIG. 1, for convenience of explanation, members other than the ink container among the members constituting the ink cartridge 10 are not shown.

  The label 12 attached to a specific surface of the ink cartridge 10 shown in FIG. 1A is separated from the ink cartridge 10 in the next step (separation step). At this time, the surface layer (at least part of) of the surface of the ink cartridge 10 to which the label 12 is attached is cut.

  Examples of the fixing means 21 for fixing the ink cartridge 10 include a member that presses and fixes the ink cartridge 10 such as a pin. The fixing means 21 is used for the purpose of preventing the ink cartridge from shifting from the fixing position in the next step (separation step).

(1b) Separation process (FIG. 1 (b))
Next, with the ink cartridge 10 fixed, the label 12 is separated from the ink cartridge 10 using the cutting means 22 (FIG. 1B).

  The cutting means 22 used in this step is, for example, an end mill shown in FIG. In the present invention, a cutting machine such as a plane or a milling cutter may be used instead of the end mill. End mill 22 of Drawing 1 (b ') has shaft part 22a which rotates, and has a plurality of blade parts 22b on the perimeter of this shaft part 22a. The cutting means 22 makes the shaft part 22a which has the blade part 22b contact the label 12, rotating as FIG.1 (b) shows. When the blade 22b of the cutting means 22 comes into contact with the label 12, the label 12 and the surface layer (at least a part thereof) of the surface of the ink cartridge 10 to which the label 12 is attached are cut. After the shaft portion 22a having the blade portion 22d comes into contact with the label 12, the ink cartridge 10 and the cutting means 22 are relatively moved by a moving means (not shown) that moves the ink cartridge 10 and / or the cutting means 22 or both. It may be moved. By doing so, the entire surface can be cut in about 2 seconds. In FIG. 1, the cutting means 22 is moved along the longitudinal direction of the surface to which the label 12 is attached. However, the cutting time can be shortened by moving the cutting means 22 along the short direction. Further, the cutting means 22 is provided with a collecting means 23 for collecting the cutting pieces generated in this step, and the cutting pieces generated in this step (particularly during cutting) are collected by the collecting means 23. The As the recovery means 23, for example, a suction device can be used.

(1c) Step of separating the ink cartridge from the cutting means (FIG. 1 (c))
After the separation step described above (FIG. 1B), the ink cartridge 10 separated from the cutting means 22 is set in a state where the fixing means 21 can be released and moved, and then the ink cartridge 10 is moved. It is transported to another apparatus system (FIG. 1C). A specific apparatus system in which the ink cartridge 10 is transported next will be described later.

  By cutting the surface layer of the predetermined surface of the ink cartridge 10 by the process described above, the label 12 attached to the predetermined surface can be separated from the ink cartridge 10. For this reason, compared with the case where the ink cartridge 10 is cut | disconnected with a circular saw etc. and the label 12 is isolate | separated, the quantity of shavings can be reduced markedly.

  Next, an ink cartridge used in the process of FIG. 1 will be described. FIG. 2 is a schematic perspective view showing an example of an ink cartridge from which labels are separated in the process of FIG. The ink cartridge 10 shown in FIG. 2A includes a main body case 11 corresponding to the body portion, a label 12 attached to the upper surface portion 13 of the main body case 11, and an ink supply port 15a provided in the bottom surface portion 15. And have. The body portion (main body case 11) of the ink cartridge 10 includes an upper surface portion 13, a side surface portion 14, and a bottom surface portion 15. The label 12 and the ink supply port 15a provided on the body portion are provided. The arrangement position is not limited to the mode illustrated in FIG.

  Hereinafter, components of the ink cartridge 10 in FIG. 2A will be described.

  The ink cartridge container 11 serving as a body part of the ink cartridge 10 is a container made of plastic such as polypropylene, for example, and is a container for storing ink (not shown). The ink stored in the ink cartridge container 11 is supplied from the ink supply port 15a to the ink head of the ink jet printer when the ink cartridge 10 is disposed in the ink jet printer (not shown). In addition, as a storage mode of the ink stored in the ink cartridge container 11, a mode in which only liquid ink is stored in the ink cartridge container 11 may be used. Moreover, the aspect accommodated in the ink cartridge container 11 in the state absorbed by ink absorbers, such as sponge, may be sufficient.

  The label 12 displays information such as the color of ink stored in the ink cartridge 10, the model number of the ink cartridge, and the model number of the corresponding inkjet printer. However, in the present invention, the information displayed on the label 12 is not limited to the color of ink stored in the ink cartridge, the model number of the ink cartridge, the model number of the corresponding ink jet printer, and the like. For example, it may be notes for use to the user. These pieces of information are printed on the label 12 using a printing material. As a printing material used for printing on the label 12, ordinary color materials such as dyes and pigments are used. However, since these color materials are different materials from the transparent polypropylene that is the material of the ink cartridge container 11, when the ink cartridge container 11 is recycled, the label 12 containing these color materials is attached. It is necessary to separate from the ink cartridge container 11.

  However, since the label 12 is welded to the main body case 11, it is difficult to separate (peel) the label 12 from the main body case 11 by a physical method using a hand or the like. Therefore, in the present invention, for example, the label 12 is separated from the main body case 11 by the process shown in FIG.

  Meanwhile, as shown in FIG. 2B, an air groove 13a and an air communication port 13b are formed on the upper surface portion 13 of the main body case 11 constituting the ink cartridge 10 illustrated in FIG. Is provided. That is, the label 12 is also a member that covers a part of the air groove 13a and the atmosphere communication port 13b, as shown in FIG. The air communication port 13b is a hole provided to equalize the air pressure between the ink storage space (not shown) and the outside of the main body case 11. The air groove 13 a is a groove whose one end is connected to the atmosphere communication port 9. The depth of the air groove 13a is preferably about 0.9 mm or more.

  The label 12 completely covers the air communication port 13b, but does not cover all the air grooves 13a. For this reason, the atmosphere communication port 13b is opened through an air groove 13a that is partially opened. The cutting means (22) used in the process of FIG. 1 cuts the entire upper surface portion 13 (lid case surface) constituting the main body case 11 shown in FIG. The thickness of the cut piece generated during the cutting by the cutting means is preferably 0.3 mm or more and 0.5 mm or less. In addition, the thickness of the cutting piece is a thickness obtained by adding the thickness of the label 12 and a part of the thickness of the main body case 11. Here, when the thickness of the cutting piece is 0.3 mm or more and 0.5 mm or less, either the atmospheric communication term 13b or the air groove 13a provided on the upper surface portion 13 is not completely cut from the main body case 11. Remains.

  FIG. 3 is a schematic plan view showing an ink cartridge label separating apparatus for carrying out the label separating process shown in FIG.

  The label separating apparatus of FIG. 3 includes a mounting table 20 for mounting the ink cartridge 10, two types of abutting means, that is, a fixed abutting means 31, a movable abutting means 32, and a position fixing means (FIG. 3). (Not shown). The ink cartridge 10 applicable to the label separating apparatus of FIG. 3 varies from the wide one shown in FIG. 3A to the narrow one shown in FIG. 3B. Here, the wide ink cartridge is a cartridge having a wide width from the surface on which the ink supply port 15a is provided to the surface on which the label 12 is provided. The label 12 attached to the ink cartridge 10 is attached in the area d in FIG.

Here, a specific label separation method using the label separation apparatus of FIG. 3 will be described. The label separation method using the label separation apparatus of FIG. 3 is a process including a step of separating the label from the ink cartridge (separation step). More specifically, the separation step includes the following steps (i) and (ii).
(I) Placement step of placing the ink cartridge on the placement surface of the placement table (ii) Position fixing step of fixing the ink cartridge to a predetermined position of the placement table

  Here, the ink cartridge container mounted on the mounting surface of the mounting table in the step (i) is conveyed to a predetermined place where the step (ii) is performed, specifically, near the end of the mounting table. The That is, the label is cut at the end of the mounting table by a cutting machine such as the above-described end mill. Then, the ink cartridge 10 transported and placed on a predetermined location on the mounting table 20 is fixed on (on the predetermined location) on the mounting table 20 by the step (ii) (position fixing step). Here, step (ii) (position fixing step) is a step for preventing the ink cartridge from moving in the in-plane direction of the mounting table from the end of the mounting table.

Hereinafter, the position fixing step will be described. The position fixing step includes at least the following step (iii), and preferably further includes the following step (iib).
(Iii) a step of moving the ink cartridge so that the end of the mounting table and the surface to which the label is attached coincide with each other (iib) the ink cartridge mounted on the mounting table is abutted from the end of the mounting table A step of fixing the position of the ink cartridge by the abutting means and the position fixing means after being shifted toward the means;

  Hereinafter, the steps (iii) and (iib) will be described sequentially.

  First, the ink cartridge 10 is moved so that the end portion of the mounting table 20 and the surface on which the label 12 is affixed coincide with each other (step (iii)). The ink cartridge 10 that separates the labels using the separation method of the present invention is disposed on the mounting table 20 so that the surface on which the label 12 is attached is one of a plurality of side surfaces of the ink cartridge 10. For this reason, the above-mentioned “so that the end portion of the mounting table 20 and the surface on which the label 12 is attached” coincides with the ink cartridge whose side surface is the surface on which the label 12 is attached. This means that the 10 side portions are aligned with the end portion of the mounting table 20.

  The ink cartridge 10 is fixed by the fixed abutting means 31 or the movable abutting means 32. For this reason, in order to bring the ink cartridge 10 into contact with the fixed abutting means 31 or the movable abutting means 32, the fixed abutting means 31 or the movable abutting from the end of the mounting table 20 by using a transport arm (not shown). The ink cartridge 10 is moved toward the means 32. That is, the ink cartridge 10 is moved in the direction of reference numerals 12 to 31. The ink cartridge 10 in contact with the fixed abutting means 31 or the movable abutting means 32 has a position where the surface on which the label 12 is stuck is slightly retracted from the end of the mounting table 20, that is, the cutting surface of the ink cartridge. It is arranged so as to be flush with 20a.

  In the label separating apparatus of FIG. 3, the fixed abutting means 31 is a means for fixing the ink cartridge 10 by abutting against the ink cartridge 10 so that the ink cartridge 10 is not displaced due to contact with the cutting means 22. It is. The fixed abutting means 31 is in contact with the surface of the ink cartridge 10 where the ink supply port 15a is provided. Here, the surface on which the ink supply port 15a is provided is a surface facing the surface on which the label 12 is attached (the surface of the lid case).

  In the label separating apparatus of FIG. 3, the cutting means 22 scrapes off the label 12 attached to the surface of the lid case of the ink cartridge 10 by using both rotational movement and translational movement as shown in FIG. 3. Separate from the ink cartridge 10. When the label 12 is separated using the cutting means 22, not only the label 12 but also at least a part of the surface layer on the surface to which the label 12 is attached is cut.

  In the label separating apparatus of FIG. 3, the movable abutting means 32 is a means for fixing the ink cartridge 10 by abutting against the ink cartridge 10 similarly to the fixed abutting means 31. However, the movable abutting means 32 is used only when the narrow ink cartridge 10 is fixed as shown in FIG. On the other hand, when fixing the wide ink cartridge 10, as shown in FIG. 3A, the ink cartridge 10 is fixed using the fixed abutting means 31. In the label separating apparatus of FIG. 3, the movable abutting means 32 is specifically a member having a shape such as a pin. Here, as shown in FIG. 3A, when cutting the wide ink cartridge 10, the movable abutting means 32 is pressed by the ink cartridge 10 and stored in the mounting surface of the mounting table 20. Therefore, it cannot be seen that it is protruding.

  The label separating apparatus of FIG. 3 provided with the two types of abutting means (fixed abutting means 31 and movable abutting means 32) of the ink cartridge 10 described above widens the object from a wide cartridge to a narrow cartridge. It is possible. The surface layer of the ink cartridge container can be cut without waste.

  Although not shown in the label separation device of FIG. 3, in addition to the abutting means described above, the ink cartridge (which constitutes the ink cartridge container) is pressed while pressing the ink cartridge from the vertical direction of the mounting table surface. Position fixing means for fixing is provided. As this position fixing means, for example, a fixing means 21 shown in FIG.

  In the above description, the case where the label 12 is affixed to the surface on which the air communication port 13b and the air groove 13a are disposed has been described, but the present invention is not limited to this. For example, when it is affixed to a surface other than the surface where the atmosphere communication port 13b and the air groove 13a are arranged, it is affixed over a plurality of surfaces including the surface where the atmosphere communication port 13b and the air groove 13a are arranged. Even if it is, it is applicable. Here, when the label 12 is affixed across a plurality of surfaces, the cutting means 22 moves relative to each other, for example, along the surface of the ink cartridge 10 and the surfaces to which the label 12 is affixed. A cutting machine that cuts the surface is used.

  The label separation method according to the first embodiment of the present invention can selectively separate only the label from the ink cartridge container by cutting with a cutting machine. For this reason, the quantity of the resin piece derived from the ink cartridge container separated from the ink cartridge container main body together with the label can be greatly reduced. For this reason, the separation method for obtaining the recycle resources used for the ink cartridge with high purity and high recovery rate can be provided.

(Second embodiment)
In the present invention, when the label is separated from the ink cartridge, the step (iib) described above, that is, the step of shifting the ink cartridge placed on the placing table in a predetermined direction is performed. Here, as a method of shifting the ink cartridge, as described in the first embodiment, there is a method of shifting from the cutting surface of the ink cartridge toward the abutting means (fixed abutting means, movable abutting means). There is, but is not limited to this. You may employ | adopt the method shifted from the direction opposite to 1st embodiment, ie, toward the direction of the cutting surface of an ink cartridge from abutting means (fixed abutting means, movable abutting means). By shifting the ink cartridge 10 in the direction of the cutting surface of the ink cartridge, the surface of the ink cartridge 10 is disposed at a position slightly protruding from the end of the mounting table 20. This position is also a position that is flush with the cutting surface 20a of the ink cartridge.

  In addition, in order to reliably remove unnecessary items (labels) from the ink cartridge container constituting the ink cartridge and to reduce the amount of the container to be cut as much as possible, the direction of shifting the ink cartridge is changed from the abutting means to the cutting surface. The direction is preferred.

(Third embodiment)
By the way, an ink cartridge may contain an ink absorber such as a sponge that is accommodated in an ink cartridge container and absorbs ink. Since this ink absorber becomes a hindrance when recycling the ink cartridge container constituting the ink cartridge, it is necessary to remove it after separating the label.

  FIG. 4 is a schematic diagram illustrating an example of an ink cartridge disassembly device. 4 is an apparatus including an ink cartridge sorting unit 2, a label separating unit 3, and an ink cartridge disassembling unit 4. 4, the ink cartridge disassembly unit 4 includes, for example, a track 41 that transports the ink cartridge 10 and a guillotine unit 42 that cuts the ink cartridge 10 transported using the track 41. Is a unit. That is, the disassembling apparatus 1 of FIG. 4 is a disassembling apparatus that disassembles the ink cartridge 10 from which the label has been separated by the method described in the first or second embodiment of the present invention, using the guillotine cutting unit 4.

  Hereinafter, the disassembling apparatus 1 of FIG. 4 and the ink cartridge disassembling method using the disassembling apparatus will be described in detail.

FIG. 5 is a schematic diagram showing a disassembly process of the ink cartridge using the disassembly apparatus of FIG. As shown in FIG. 5, the ink cartridge disassembly process using the disassembly apparatus of FIG. 4 includes the following steps (a) to (c).
(A) Label cutting process (FIG. 5 (a))
(B) Guillotine cutting step (FIG. 5 (b))
(C) Ink absorber removing step (FIG. 5C)

  In the label cutting step, the label 12 attached to the ink cartridge 10 is cut together with the surface layer on the surface to which the label is attached using the cutting means 22 (FIG. 5A). The cutting piece 12a generated by this process is collected separately from the ink cartridge container constituting the ink cartridge.

  In the next guillotine cutting step, the guillotine cutter 42a is moved up and down to cut the ink cartridge 10. The cut piece 11a generated by this cutting is collected together with the ink cartridge container constituting the ink cartridge 10 and then recycled. The cut piece generated in this step is a lid portion of the ink cartridge container constituting the ink cartridge 10.

  In the ink absorber removing process to be performed next, the push pin 54 is inserted from the ink supply port 15 a and the ink absorber 10 a exposed by cutting the ink cartridge 10 is pushed out. Thereby, the ink absorber 10 a in the ink cartridge 10 is pushed out from the cut surface of the ink cartridge 10.

  Through the above steps, the ink cartridge 10 is disassembled into at least a label, an ink cartridge container, and an ink absorber. The present invention can also be applied to an ink cartridge that does not have an ink absorber. In this case, the ink absorber removing step shown in FIG. 5C can be omitted.

  Here, each unit which comprises the dismantling apparatus 1 of FIG. 4 is demonstrated.

  The ink cartridge 10 introduced into the disassembling apparatus 1 in FIG. 4 is first transported into the ink cartridge sorting unit 2. In the ink cartridge sorting unit 2, a plurality of types of ink cartridges entering the unit are arranged on a transport belt (not shown) and then moved to the label separation unit 3 and ink cartridges that are not moved. And sort. The plurality of types of ink cartridges introduced into the ink cartridge sorting unit 2 are ink cartridges collected because they have been used.

  The ink cartridge that is not moved from the ink cartridge sorting unit 2 to the label separation unit 3 is an ink cartridge that cannot be separated or cut or both in either the label separation unit 3 or the guillotine cutting unit 4. The ink cartridge that is not moved to the label separation unit 3 includes a member that is not desired to be mixed with a part to be recycled, for example, a member that is different in material from a plastic case that is a main body. In addition, that a material differs here means that a magnitude | size and hardness differ from the parts to recycle. For sorting ink cartridges, for example, an imaging device such as a digital camera is used.

  The ink cartridge remaining in the ink cartridge sorting unit 2 is held by a mechanical arm (transport arm) such as a movable chuck and transported to the label separation unit 3. In the label separation unit 3, the label (not shown in FIG. 4) attached to the ink cartridge 10 is cut and separated using the cutting means 22. As the label separation unit 3 incorporated in the disassembling apparatus 1 in FIG. 4, for example, the label separation apparatus described in the first or second embodiment can be used. In the disassembling apparatus 1 in FIG. 4, it is preferable to have a plurality of (for example, two) cutting means 22 from the viewpoint of work efficiency. Then, the ink cartridge 10 from which the label has been separated is conveyed to the guillotine cutting unit 4. On the other hand, the label and the cut piece separated using the cutting means 22 are collected by a collection device (not shown) provided in the label separation unit 3.

  FIG. 6 is a schematic cross-sectional view showing an example of the ink cartridge 10 disassembled by the disassembly apparatus 1 of FIG. The ink cartridge 10 in FIG. 6 includes an ink cartridge container 11, a label 12 attached to the upper surface portion 13 of the ink cartridge container 11, and an ink absorber 10 a stored in the ink cartridge container 11. Have. Here, the ink cartridge container 11 is an ink cartridge container including a side surface portion (14a, 14b), an upper surface portion (lid portion) 13, and a bottom surface portion (not shown).

A protrusion 17 is provided on the back surface of the upper surface portion (lid portion) 13 of the ink cartridge container 11. The protrusion 17 is used as a support member that fixes the ink absorber 10 a inside the ink cartridge container 11. Further, by providing the protrusion 17, a space is provided between the upper surface portion (lid portion) 13 of the ink cartridge container 11 and the ink absorber 10a. This space contains air, and the air contained in this space is connected to the outside air and the ink cartridge container via an air communication port (not shown) provided on the upper surface portion (lid portion) 13 of the ink cartridge container 11. 11 Plays the role of aligning pressure with the inside.

  The thickness of the label 12 attached to the upper surface portion (lid portion) 13 of the ink cartridge container 11 is preferably 0.1 mm or less. Moreover, the thickness of the upper surface part 13 is preferably 1.5 mm or more and 2 mm or less. Furthermore, the depth of the air groove 13a provided in the upper surface part 13 is preferably about 0.9 mm or more. And the length of the protrusion 17 provided in the back surface of the upper surface part 13 becomes like this. Preferably they are 4 mm or more and 5 mm or less.

  Next, label separation will be described with reference to FIG. When the label 12 is affixed to the upper surface portion (lid portion) 13 of the ink cartridge container 11, the surface of the label 12 is at a position 0-0 'in FIG. Here, when the label 12 is separated using the cutting means 22 provided in the label separation unit 3, the upper surface portion (lid portion) 13 of the ink cartridge container 11 is cut to the position aa 'in FIG. It's okay. That is, when the label 12 is separated, the upper surface portion (lid portion) 13 of the ink cartridge container 11 is partially cut so that the air groove 13a remains.

  In FIG. 6, the distance between 0-0 ′ and aa ′, that is, the sum of the thickness of the label 12 and the cutting thickness of the upper surface portion (lid portion) 13 of the ink cartridge container 11 is preferably 0. .3 mm or more and 0.5 mm or less. By adjusting the cutting thickness of the upper surface portion (lid portion) 13 in this way, not only can the label be removed reliably in a shorter time than when manually peeling, but also the upper surface portion compared to the case where a circular saw is used. The loss amount of the (lid) and the generation of scattered debris can be significantly reduced.

  In the ink cartridge 10 from which the label 12 has been separated, the upper surface portion (lid portion) 13 of the ink cartridge container 11 is cut from the main body of the ink cartridge container 11 in the next step (guillotine cutting step). At this time, the cutting position by the guillotine cutter is not bb ′ (upper surface of the upper surface portion) or dd ′ (upper surface of the ink absorber), but cc ′ (intermediate between the upper surface of the upper surface portion and the upper surface of the ink absorber). ).

  C-c ', which is the cutting position of the ink cartridge cut in the guillotine cutting step described later, is preferably 2.1 mm or more and 5.6 mm or less with reference to 0-0'.

FIG. 7A is a diagram showing a first example of an end mill which is a cutting member for separating a label. FIG. 7B is a diagram illustrating an upper surface portion (lid) of the ink cartridge container by the end mill of FIG. It is a top view which shows the cutting pattern which appears in a part. The end mill shown in FIG. 7A is a standard end mill, and has a shaft portion and a blade on each side surface of the shaft portion. In the end mill of FIG. 7A, the shaft portion rotates, and at least one of the shaft portion or the workpiece is moved in a direction intersecting the shaft, thereby cutting the workpiece. Here, when the end mill of FIG. 7A is used, a periodic cutting pitch shown in FIG. 7B with the width d ₁ as one period appears.

  FIG. 8A is a view showing a second example of an end mill which is a cutting member for separating a label, and FIG. 8B shows an upper surface portion (lid) of the ink cartridge container by the end mill of FIG. It is a top view which shows the cutting pattern which appears in a part. The end mill in FIG. 8A is a so-called luffing end mill. When the end mill shown in FIG. 8A is used, the periodic cutting pitch shown in FIG. 8B appears. Specifically, a cutting trace that intersects the longitudinal direction of the surface and a trace that intersects the trace appear.

  When trying to separate the label 12 from the upper surface portion (lid portion) 13 of the ink cartridge container using the end mill of FIG. 7A or FIG. Even if this cutting mark is generated, the surface of the ink cartridge 10 is almost flat, and the air communication port 13b and the air groove 13a remain. The end mill of FIG. 7A or FIG. 8A is used for the purpose of separating the label attached to the ink cartridge (used ink cartridge) to be disassembled from the ink cartridge. The embodiment is not limited to this. For example, it may be used when the sticker attached to the ink cartridge is replaced.

  The ink cartridge 10 from which the label has been separated is held by a movable chuck and conveyed to the guillotine cutting unit 4. In the present invention, guillotine cutting refers to a cutting method in which a single blade moves vertically and horizontally while pushing the object, thereby cutting the object without producing chips.

  The guillotine cutting unit 4 includes a plurality of tracks 41 and guillotine units 42, respectively. In each track 41, a plurality (for example, two) of ink cartridges 10 conveyed from the label separation unit 3 are arranged side by side. The ink cartridges 10 arranged in each track 41 are transported by transport means (not shown) and are cut in order by the guillotine unit 42. It takes about 1 second for one guillotine unit 42 to cut one ink cartridge. The number of tracks 41 is the same as the number of guillotine units 42, and one track 41 corresponds to one guillotine unit 42.

  The reason why the ink cartridge is cut using the guillotine unit 42 in the guillotine cutting unit 4 is that the generation of shavings can be significantly reduced as compared with the case of cutting with a circular saw.

  In the disassembling apparatus 1 in FIG. 4, the guillotine cutting unit 4 cuts a lid (lid case) from the main body case of the ink cartridge 10 and divides it into the lid and the remaining case. Here, the lid is the portion of the ink cartridge main body case where the label is attached, but since the label is separated at the time of cutting by the guillotine cutting unit 4, it can be recycled together with the remaining case. it can.

  On the other hand, since the ink absorber remains in the case remaining portion, it is separated from the case by using an ink absorber take-out means (for example, a pusher) described later.

  As described above, when the disassembling apparatus 1 shown in FIG. 4 is used, the ink cartridge can be disassembled into each member including a label portion, a lid portion, a case remaining portion, and an ink absorber.

  Next, the guillotine cutting unit 4 will be described in more detail. 9 is a schematic diagram showing a specific structure of a guillotine unit 42 included in the guillotine cutting unit 4 provided in the dismantling apparatus 1 of FIG. 4, wherein (a) is a front view and (b) is a side view of the guide rail side. FIG.

  The guillotine unit 42 in FIG. 9 includes a guillotine cutter 42a that is a flat blade, and a warp preventing member 42b that fixes the guillotine cutter 42a while sandwiching the guillotine cutter 42a. The guillotine unit 42 also includes a slide rail 42c, a holder part 42e, and a shaft 42d attached to the holder part 42e.

  In the guillotine unit 42 of FIG. 9, the left and right side surfaces of the warp preventing member 42b are in sliding contact with the guide rails 42c, respectively. Further, in the guillotine unit 42 of FIG. 9, a holder portion 42e is attached to the upper portion of the warp preventing member 42b. In the guillotine unit 42 of FIG. 9, the shaft 42d is moved up and down as shown by the arrow in FIG. 9A by an urging means (not shown), so that the guillotine cutter 42a and the warp preventing member 42b are moved together. Move up and down.

  In the guillotine unit 42 of FIG. 9, the warp preventing member 42b is provided for the purpose of preventing the guillotine cutter 42a from warping due to the force when cutting the ink cartridge. In addition, an opening for exposing the blade of the guillotine cutter 42a is provided in the lower portion of the warp preventing member 42b. The ink cartridge is cut by the guillotine cutter 42a exposed from the opening.

  In the guillotine unit 42 of FIG. 9, the warp preventing member 42b is composed of a front-side member b1 and a back-side member b2, as shown in FIG. 9B, and the guillotine cutter 42a is sandwiched between these members. ing. In the warp prevention member 42b, the front-side member b1 and the back-side member b2 are provided with openings for exposing the blades of the guillotine cutter 42a in the lower part.

  FIG. 10 is a schematic diagram showing a guillotine cutting step and an ink absorber separating step performed by the guillotine unit in the disassembling apparatus of FIG. Hereinafter, the guillotine cutting step and the ink absorber removing step will be described with reference to FIG.

  First, using the positioning pin 52, the ink cartridge 10 is moved to the cutting position while pressing the ink cartridge 10 mounted on the mounting table 20. Next, the ink cartridge 10 moved to the cutting position is fixed using the position fixing means 51 and the pressing pin 53 (FIG. 10A). At this time, the position fixing means 51 fixes the ink cartridge 10 by pressing the body portion of the ink cartridge container constituting the ink cartridge 10 (portion 11 in FIG. 2A). Further, the pressing pin 53 contacts the surface having the ink supply port 15 a constituting the ink cartridge 10 and fixes the ink cartridge 10.

  The ink cartridge 10 fixed by the above process separates the lid portion 11a of the ink cartridge container constituting the ink cartridge 10 from the container main body using the guillotine cutter 42a (FIG. 10B). Specifically, this step is a step of inserting the blade of the guillotine cutter 42a at the dotted line position in FIG. In addition, in FIG.10 (b), although the position of the guillotine cutter 42a is inside the edge part of the mounting base 20, in this invention, it is not limited to this aspect. Further, when cutting the ink cartridge container constituting the ink cartridge 10 using the guillotine cutter 42a, as shown in FIG. 10B, the positioning pin 52 is set before the lid portion 11a of the ink cartridge container is cut off. Separated from the ink cartridge 10.

  When an ink absorber that absorbs ink is provided in the ink cartridge 10, the ink absorber 10a is pushed out from the ink supply port (not shown in FIG. 10) using the push pin 54 (FIG. 10C). )). When pushing out the ink absorber 10a, the guillotine cutter 42a is lifted upward in advance as shown in FIG. 6C.

  In the disassembling apparatus 1 in FIG. 4, there is one guillotine cutter used to disassemble one ink cartridge, and the ink cartridge is cut while being pushed between the mounting tables. However, the present invention is not limited to this, and as a guillotine cutter used for disassembling one ink cartridge, two guillotine cutters whose blades face each other are used to cut an ink cartridge disposed therebetween. There may be.

  The ink cartridge disassembling apparatus of the present invention is an apparatus for disassembling an ink cartridge using a guillotine cutter. Specifically, cutting can be performed by bringing the blade into contact with the ink cartridge along the longitudinal direction of the surface to be cut out of the surfaces of the ink cartridge and moving along the short direction of the surface. However, the ink cartridge may be cut by abutting the blade along the short direction of the surface to be cut and moving along the longitudinal direction.

(Fourth embodiment)
FIG. 11 is a schematic diagram illustrating another example of an ink cartridge disassembly apparatus. The disassembling apparatus of FIG. 11 has a plurality of turntables (hereinafter sometimes referred to as “index tables”) that transport ink cartridges. Then, a first dismantling process for removing at least a part of the ink cartridge including one surface is performed on one turntable. Next, after the ink cartridge partially removed by the first disassembly process is transferred to another rotating table, at least a part of the ink cartridge including a surface different from the one surface on the other rotating table is removed. A second dismantling process to be removed is performed.

  The ink cartridge that has passed through the ink cartridge sorting unit is carried into the disassembling apparatus of FIG. The ink cartridge sorting unit is the same as the disassembling apparatus shown in FIG. Note that the ink cartridge 10 shown in FIG. 11 has a locking member 18 that can be engaged with and disengaged from the recording apparatus, and a label 12 is attached to the upper surface portion 13.

  In the disassembling apparatus of FIG. 11, a first index table 61 and a second index table 62 are juxtaposed. That is, the first index table 61 and the second index table 62 exist in the same plane and exist in the horizontal direction. 11 includes a first carry-in mechanism 64a and a second carry-in mechanism 64b for carrying the ink cartridge into the first index table 61, and the first carry-in mechanism 64a and the second carry-in mechanism. 64b is configured to carry ink cartridges to different positions of the first index table 61. The first index table 61 and the second index table 62 have a plurality of gripping members 63, grip the plurality of ink cartridges 10, and transport the ink cartridges 10. The gripping member 63 shown in FIG. 11 can grip the two ink cartridges 10 side by side in the circumferential direction, and the gripping member 63 of the first index table 61 is loaded from the first loading mechanism 64a. The ink cartridge and the ink cartridge carried from the second carry-in mechanism 64b can be gripped simultaneously.

  The direction of rotation of the first index table 61 is different from the direction of rotation of the second index table 62. Around the first index table 61 and the second index table 62, means necessary for disassembling the ink cartridge, such as the cutting means 22 and the guillotine unit 42, are arranged at appropriate positions. During the conveyance by the first index table 61, necessary disassembly processing steps are performed on the bottom surface portion 15 of the ink cartridge 10, such as a first disassembly processing for removing at least a part of the ink cartridge 10 including the bottom surface portion 15. Is called. After the ink cartridge 10 is transferred to the second index table 62, during the transport by the second index table 62, a second dismantling process for removing at least a part of the ink cartridge 10 including the upper surface portion 13, etc. Necessary processes are performed on the upper surface portion 13 of the ink cartridge 10.

  In the disassembling apparatus of FIG. 11, first, the type of the ink cartridge that has been carried in is determined. For the discrimination, for example, an imaging device such as a digital camera is used. The gripping member 63 of the first index table 61 grips the ink cartridge 10 at an appropriate position according to the determined model so that the bottom surface portion 15 is on the outside. As the first index table 61 rotates, the ink cartridge 10 is transported to the next process. During the conveyance by the first index table 61, a necessary process is performed on the bottom surface portion 15 side of the ink cartridge 10. As a process required with respect to the bottom face part 15 side, a flexible printed circuit board (FPC) removal process etc. are mentioned, for example.

  After the necessary steps are completed on the bottom surface 15 side of the ink cartridge 10, the ink cartridge 10 is transferred to the second index table 62 by a mechanical arm (conveyance arm) such as a movable chuck. At this time, the gripping member 63 of the second index table 62 grips the ink cartridge 10 at an appropriate position according to the determined model so that the upper surface portion 13 is on the outside. Therefore, the processing surface can be changed without reversing the direction of the ink cartridge 10. Note that the gripping member 63 of the first index table 61 after the ink cartridge 10 is transferred is cleaned through a cleaning process before the ink cartridge 10 is gripped again.

As the second index table 62 rotates in the opposite direction to the first index table 61, the ink cartridge 10 is transported to the next process. During the conveyance by the second index table 62, a necessary process is performed on the upper surface portion 13 side of the ink cartridge 10. As a process required with respect to the upper surface part 13 side, the following process (a) thru | or (c) shown in FIG. 5 is mentioned, for example.
(A) Label cutting process (FIG. 5 (a))
(B) Guillotine cutting step (FIG. 5 (b))
(C) Ink absorber removing step (FIG. 5C)

  Details of each step are as described in the third embodiment. However, since the ink cartridge 10 is held by the holding member 63, it is not always necessary to fix the position by the position fixing means 51, the positioning pin 52, the pressing pin 53, etc. in the guillotine cutting process. For example, the gripping member 63 protrudes to a predetermined position toward the guillotine unit 42 arranged around the second index table 62, or the guillotine unit 42 protrudes to the predetermined position toward the gripping member 63, and after cutting. By returning to the original position, the guillotine cutting step can be performed. Of course, the guillotine unit 42 and the gripping member 63 may be relatively close to each other and return to the original position after cutting.

  If the ink cartridge has a light guide member, for example, a light guide member removal step may be performed between the label cutting step and the guillotine cutting step. The light guide member can be pushed out by inserting an extrusion pin, for example. Note that the gripping member 63 of the second index table 62 after unloading the ink cartridge 10 is cleaned through a cleaning process before gripping the ink cartridge 10 again.

  The disassembling apparatus of FIG. 11 includes carry-out mechanisms 66a to 66c that carry out the ink cartridge after the disassembly process from the second index table 62. The remainder of the main body case is carried out from the mechanism 66c. The carry-in mechanisms 64 a and 64 b and the carry-out mechanisms 66 a to 66 c exist on the opposite sides of the straight line 65 connecting the center of the first index table 61 and the center of the second index table 62.

  The disassembling apparatus in FIG. 11 requires less installation space than the line type apparatus because the ink cartridge is conveyed by the index table. Further, since the two index tables are juxtaposed, the processing surface can be changed without reversing the ink cartridge when the ink cartridge is transferred between the index tables. In addition, since the two index tables are rotated in opposite directions, the carry-out port can be set at a position different from the carry-in port while reducing the number of grip members that are not gripping the ink cartridge as much as possible. In the example of FIG. 11, two index tables are used. However, as shown in FIG. 12, the same applies when three or more index tables are used.

(Fifth embodiment)
Of the ink cartridges disassembled by the ink cartridge disassembling apparatus and the ink cartridge disassembling method described above, the ink cartridge container is recycled (regenerated) by the method described below.

  FIG. 13 is a flowchart showing an example of a process for producing a recycled ink cartridge from a collected used ink cartridge container. Hereinafter, each process will be described with reference to the flowchart of FIG.

  First, a label affixed to a predetermined surface of the collected used ink cartridge and an ink absorber that absorbs ink contained in the ink cartridge container are separated from the container (separation step). In performing this step, the label separation method of the present invention and the ink cartridge disassembly method described above can be used. Here, the label separated from the ink cartridge using the label separation method of the present invention is not reused. This is because although the surface layer portion of the ink cartridge remains on the label, the amount thereof is very small. On the other hand, the ink absorber taken out from the ink cartridge container may be reused by other reuse means.

  Next, in the separation step, the main body and the lid portion of the collected ink cartridge container are washed to wash away paint and pigment that can adhere to the inner wall surface of the container (washing step). When obtaining a recycling container, the lid part of the ink cartridge container (cut piece cut by the guillotine cutter) and the remaining part of the ink cartridge container are made of the same material and can be easily recycled. Next, after crushing both the main body and the lid part of the ink cartridge container (crushing step), the crushed pieces (plastic pieces) generated during crushing are melt-molded to obtain pellets (pelletizing step). Then, the pellet is melt-molded to form a molded product of the ink cartridge (molding process). An ink cartridge container regenerated through the above steps is obtained. The shape of the regenerated ink cartridge container may be the same as or different from the shape of the ink cartridge container at the time of collection. In addition, the material used when producing the regenerated ink cartridge container is a pellet obtained from the recovered ink cartridge container, and this pellet and an unused material (virgin material) are mixed and regenerated. An ink cartridge may be manufactured.

  The process described above is a process for producing a recycled ink cartridge container from the collected used ink cartridge container. However, the present invention is not limited to this. For example, the process described above can be used as a process for manufacturing a light-shielding portion that is attached to the outside of a storage container that stores ink. The light-shielding portion is a member that has a light-transmitting pellet material (polypropylene) and a light-shielding color pigment and does not come into direct contact with ink. Further, when the light shielding part is produced as a recycled product from the collected used ink cartridge container, some ink components may be mixed in the resin.

(Sixth embodiment)
(Example 1)
By the method described below, the ink cartridge in which the label was attached to the lid and the ink absorber was accommodated inside was disassembled. The used ink cartridge container weighs 15 g, of which the label weighs 0.1 g.

(1) Label Separation Step A standard end mill is brought into contact with the surface of the lid portion on which the label of the ink cartridge container is affixed to separate the label from the ink cartridge container and the surface layer on the surface on which the label is affixed. The part was cut. At this time, the depth of cutting was in the range of 0.3 mm to 0.5 mm from the label surface.

(2) Disassembly process Next, the ink cartridge container was cut using a guillotine cutter, and the container lid was cut from the ink cartridge container main body. At this time, the cutting position of the guillotine cutter was set at a depth of 1.8 mm to 5.1 mm with reference to the cutting surface of the ink cartridge container. In this position range, there is a protrusion provided on the inner surface of the container lid, so this step is specifically a step of cutting the protrusion provided on the inner surface of the container lid with a guillotine cutter. It is.

  After cutting with a guillotine cutter, the ink absorber contained in the ink cartridge container was taken out from the ink cartridge container.

  In this way, the ink cartridge was disassembled into a container body (ink cartridge container), a container lid, a label, and an ink absorber.

  Here, based on the weight of the ink cartridge container before disassembly, the weight ratio of the container main body, the container lid, the cutting piece attached to the separated label and the cutting waste generated by cutting the ink cartridge container was evaluated. . The evaluation results are shown in Table 1 below. Here, the cutting waste refers to a waste that cannot be collected together with the container body as cutting waste of the ink cartridge container.

(Example 2)
The ink cartridge was disassembled in the same manner as in Example 1 except that the label separation step was omitted in Example 1 and the lid was cut with a circular saw instead of a guillotine cutter in the disassembly step.

  Moreover, the weight fraction of a container main body, a container cover part, a resin piece, and a cutting waste was evaluated by the same method as Example 1. The evaluation results are shown in Table 1 below.

(Example 3)
In Example 1, the ink cartridge was disassembled by the same method as in Example 1 except that the disassembling step was performed by omitting the label separation step.

  Further, by the same method as in Example 1, the weight fraction of the container main body, the container lid part to which the label was attached, and the cutting waste was evaluated. The evaluation results are shown in Table 1 below.

  From Example 1 and Example 3, when the ink cartridge was cut using a guillotine cutter, cutting waste generated when the ink cartridge was cut using a circular saw was not generated. For this reason, it can be said that the disassembling method of the present invention is excellent in terms of recycling containers (ink cartridge containers), specifically, recycling resources. Moreover, in Example 1, before the ink cartridge was cut, the label that hinders recycling could be separated by separating the label from the container lid in the separation step. For this reason, since a container lid part can also be turned to recycling with a container main body, the recycling rate improved. As a result, in Example 1, although there was a slight loss of material in the label separation process, containers that are recycled resources can be collected from the collected used ink cartridges (containers) at a recycling rate of almost 100%. It was.
