Description

Technical Field

[0001] The present invention relates to a used disposable diaper processing apparatus that reduces weight by separating water from the superabsorbent polymer contained in the used disposable diaper.

[0002] More specifically, the present invention relates to a used disposable diaper processing apparatus that reduces the weight by dehydrating after reducing the amount of water contained in the used disposable diaper by mixing a superabsorbent polymer that has absorbed the water contained in the excrement with a chemical containing a divalent metal ion or the like to reduce the water absorption function of the superabsorbent polymer and separate the water.

Background Art

[0003] Used disposable diapers contain a large amount of water, so the weight can be a problem when handling a large amount of used disposable diapers, such as in nursing facilities. For the disposable diaper, a surface material sheet that allows water to pass through is used on the inner side that contacts the body, and a waterproof material sheet that does not allow water to pass through is used on the outer side. Between the surface material sheet and the waterproof material sheet, pulp and a superabsorbent polymer are filled as a water absorbent. The superabsorbent polymer can hold a large amount of water, and once the water is absorbed by the superabsorbent polymer, it is difficult for the water to separate as it is.

[0004] Therefore, a used disposable diaper processing apparatus has been proposed that stirs the used disposable diaper together with a chemical containing a divalent metal ion or the like to reduce the water absorption function of the superabsorbent polymer and separate the water, and then performs a dehydration process to reduce the amount of water contained in the used disposable diaper and reduce the weight (see Patent Document 1).

[0005] Figure 10 shows a side view of a conventional used disposable diaper processing apparatus 101 described in Patent Document 1. The conventional used disposable diaper processing apparatus 101 in Figure 10 includes a processing tank 120, a liquid supply unit 110, a liquid discharge unit 109, a take-out unit 106, an input door 102, an apparatus main body 103, a storage container 107, a waste bag 108, a control device 111, a shaft 113, and a belt 114. The processing tank 120 is composed of an inner tank 105 and an outer tank 104. Further, at the lower part of the processing tank 120, an outer tank bottom 115 and an inner tank bottom 117 that can be opened and closed are provided.

[0006] Next, the operation of the conventional used disposable diaper processing apparatus 101 will be described.

[0007] Water is introduced from the liquid supply unit 110 into the outer tank 104, and a certain amount of water is stored in the outer tank 104. Next, a chemical agent that reduces the water absorption function of the superabsorbent polymer is introduced from the liquid supply unit 110 into the outer tank 104, mixed with the water already introduced into the outer tank 104, and the processing liquid is stored in the outer tank 104. As the chemical agent, those containing divalent metal ions such as calcium chloride are preferable.

[0008] Next, the used disposable diaper is introduced into the inner tank 105 through the input door 102. Under the control of the control device 111, the motor 112 rotates, causing the shaft 113 to rotate via the belt 114, and the inner tank 105 connected to the shaft 113 rotates, and a stirring process is performed in the processing tank 120. When the stirring operation continues for about 10 to 30 minutes, the superabsorbent polymer in the used disposable diaper reacts with, for example, divalent metal ions in the chemical agent, causing the water contained in the superabsorbent polymer to be separated. Next, after discharging the liquid such as the processing liquid accumulated in the outer tank 104 from the liquid discharge unit 109, the inner tank 105 is rotated at high speed with respect to the outer tank 104 to dehydrate the used disposable diaper and reduce the weight of the used disposable diaper. When the outer tank bottom 115 and the inner tank bottom 117 are opened in the state where the dehydration is completed, the used disposable diaper falls into the waste bag 108 installed in the storage container 107. In this way, it is possible to store the used disposable diapers with reduced volume in the disposal bag 108 without disturbing the operator's hands, and it is possible to reduce the operator's workload and hygienic burden.

Summary of the Invention

Problems to be Solved by the Invention

[0010] However, in the used disposable diaper processing apparatus 101 described in Patent Document 1, in order to separate the moisture contained in the used disposable diapers, a stirring operation of about 10 to 30 minutes is required. Once the weight reduction process is started, it is not possible to put the used disposable diapers into the processing apparatus 101 halfway. In addition, since the operator does not necessarily have to perform the diaper loading process when the weight reduction process is completed, a non-operating time (i.e., standby time) occurs until the next diaper weight reduction process is started, and there is a problem that the processing amount is limited.

[0011] In view of such points, the present invention can hold used disposable diapers in the apparatus even during the weight reduction process, and each time the weight reduction process is completed, it is possible to input the unprocessed used disposable diapers and start the next weight reduction process, eliminating the standby time and enabling a large number of diapers to be weight-reduced by one apparatus. An object of the present invention is to provide a used disposable diaper processing apparatus. In other words, the present invention provides a used disposable diaper processing apparatus capable of reducing the weight of a large number of used disposable diapers with one apparatus by eliminating the standby time of the used disposable diaper processing apparatus.

Means for Solving the Problems

[0012] In order to solve the above problems, according to one aspect of the present invention Used paper diapersThe processing device includes Used paper diapers a processing tank for processing above the upper part of the processing tank, a plurality of holding parts capable of holding the Paper diapers respectively, a continuous feeding part having a holding part rotation driving part for rotationally driving each holding part to an input position above an opening connected to the processing tank and other standby positions, When the holding part rotates to the input position by the holding part rotation driving part, the Paper diapers held by the holding part is fed from the opening into the processing tank Together with , The continuous feeding unit includes a cylindrical portion with upper and lower openings and rotated by the holding unit rotation driving unit, and a cylindrical portion storage case having a bottom surface other than the opening and the opening, and the cylindrical portion is disposed inside thereof. The plurality of holding portions are configured by partitioning the cylindrical portion with partition plates, and a winding prevention portion having a slope that extends along the lower edge of each of the partition plates and lifts the paper diaper upward is provided at least on the front side in the rotation direction of the cylindrical portion. The cylindrical portion storage case further includes a direct feeding door and a storage feeding door that are respectively attached to the upper portion thereof so as to be openable and closable. The direct feeding door is disposed so as to face the holding portion located at the feeding position, and the storage feeding door is disposed so as to face the holding portion located at the standby position. During the operation of the used paper diaper processing device, the storage feeding door is opened, and the used paper diaper to be processed can be fed into the holding portion at the standby position. When the processing of the paper diaper fed into the processing tank is completed, the paper diaper held by the holding portion at the standby position is automatically fed into the processing tank, and further includes a control device for continuously performing the processing.

Advantages of the Invention

[0013] According to the used diaper processing device according to the above aspect of the present invention, even when the used diaper processing device is in operation, an operator can hold the collected used diapers in the holding parts of the continuous feeding part, so that the used diapers can be held by the device even during the weight reduction process. And immediately after the weight reduction process is completed, the used diapers held by the holding part can be put into the processing tank to start the next weight reduction process immediately. Therefore, it is possible to eliminate the non-operating time of the device. In addition, since it is not necessary for the operator to start the next weight reduction process in anticipation of the timing when the weight reduction process is completed, it is also possible to reduce the burden on the operator for operating the device. That is, it is possible to efficiently perform the weight reduction process of used diapers without bothering the operator.

Mode for Carrying Out the Invention

[0015] [Embodiment 1] Hereinafter, with reference to the drawings, the used disposable diaper processing apparatus 1 according to an embodiment of the present invention will be described in detail. The same or corresponding parts in the drawings are denoted by the same reference numerals and their description will not be repeated. In order to make the description easier to understand, in the drawings referred to below, the configuration is shown in a simplified or schematic manner, or some of the constituent members are omitted. Also, the dimensional ratios between the constituent members shown in each figure do not necessarily represent the actual dimensional ratios.

[0016] [Overall Configuration] First, the overall configuration of the used disposable diaper processing apparatus 1 will be described. FIGS. 1A and 1B show the configuration of the used disposable diaper processing apparatus 1 according to Embodiment 1 of the present invention. Specifically, FIG. 1A is a side cross-sectional view of the used disposable diaper processing apparatus 1, and FIG. 1B is a top view of the cylindrical portion 25 with the direct input door 21 and the storage input door 22 omitted in the used disposable diaper processing apparatus 1.

[0017] The used disposable diaper processing apparatus 1 includes at least a processing tank 20, a liquid supply unit 10, a liquid discharge unit 9, a take-out unit 6, and a continuous input unit 23. More specifically, the used disposable diaper processing apparatus 1 further includes a direct input door 21, a storage input door 22, an apparatus main body 3, a storage container 7, a waste bag 8, a control device 11, and a rotational drive unit 70.

[0018] The processing tank 20 for reducing the weight of used disposable diapers is disposed in the upper part within the apparatus main body 3, and is composed of, for example, a circular cylindrical outer tank 4 and an inner tank 5 that can store used disposable diapers 18 and is, for example, circular cylindrical. The inner tank 5 is disposed within the outer tank 4.

[0019] The upper part of the inner tank 5 is configured as an upper conical portion 5b that is a wide mouth portion for easily inserting used disposable diapers 18, and the middle part is composed of a cylindrical portion 5c that follows the upper conical portion 5b.

[0020] The outer tank 4 is composed of a cylinder coaxial with the inner tank 5.

[0021] The continuous input section 23 has, at least, a plurality of holding sections 24 capable of holding the used paper diapers 18 respectively at the upper part of the treatment tank 20, an input position I above the opening 27 connected to the treatment tank 20, and a holding section rotation drive section 28 that rotationally drives each holding section 24 to other standby positions II. Specifically, the continuous input section 23 is composed of a cylindrical section 25 having input slots 24 that function as an example of the holding section, a cylindrical section storage case 26, an opening 27, and a cylindrical section rotation drive section 28 that functions as the holding section rotation drive section 28. The cylindrical section 25 has no bottom surface, and a plurality of input slots 24 for storing a plurality of used paper diapers 18 are arranged while being partitioned from each other in the circumferential direction. The cylindrical section storage case 26 is a cylindrical member fixed to the upper end of the apparatus main body 3, has a bottom surface 26a other than the opening 27, and the cylindrical section 25 is disposed inside. Fig. 1B shows a top view of the cylindrical section storage case 26 and the cylindrical section 25. The cylindrical portion of the cylindrical section 25 has openings at the upper and lower portions. In this example, the input slots 24 are partitioned by partition plates 36 and four are arranged. For convenience, the input slot 24 located at the input position I overlapping the opening 27 is directly referred to as the input slot 24a, and the other input slots 24 located at the standby position II other than the input position I overlapping the opening 27 are referred to as standby slots 24b. Note that the input slots 24 are not limited to being partitioned by the partition plates 36, and a plurality of cylindrical slot portions such as four may be arranged on one circumference so that all the slot portions are integrally rotationally driven. The opening 27 is formed to penetrate a part of the bottom surface 26a of the cylindrical section storage case 26, connects a part of the inside of the cylindrical section 25 in the cylindrical section storage case 26 and the treatment tank 20, and enables the used paper diapers 18 in the cylindrical section 25 to fall into the treatment tank 20. The cylindrical part rotation drive unit 28 is a motor as an example. The rotating shaft of the motor 28 is connected to the central shaft part 25b of the cylindrical part 25, and under the control of the control device 11, the cylindrical part 25 rotates with respect to the cylindrical part storage case 26 by the rotational drive of the motor 28, so that the input slot 24 is located at the input position I that overlaps the opening 27 in sequence.

[0022] The direct input door 21 and the storage input door 22 are attached to the upper part of the cylindrical part storage case 26 of the continuous input part 23 so as to be openable and closable. The direct input door 21 is arranged so as to face the input slot 24 located at the input position I overlapping the opening 27. The storage input door 22 is arranged so as to face the other input slots 24 located at the standby position II other than the input position I overlapping the opening 27. Therefore, the used disposable diaper 18 input from the direct input door 21 is directly input into the inner tank 5 through the opening 27. The used disposable diaper 18 input from the storage input door 22 is held in the standby slot 24b.

[0023] The outer tank 4 is a container that can store water. It is possible to store water by introducing water from the liquid supply unit 10 into the treatment tank 20, and chemicals can also be introduced from the liquid supply unit 10 into the treatment tank 20. As a result, the treatment liquid 19 can be supplied from the liquid supply unit 10 into the treatment tank 20. Although it will be described in detail later, it is also possible to supply the treatment liquid 19 obtained by mixing water and chemicals from the liquid supply unit 10 into the treatment tank 20.

[0024] Also, the liquid discharge part 9 is used to discharge the liquid in the outer tank 4 to the outside. Inside the outer tank 4, a cylindrical inner tank 5 having a plurality of through holes 5a on at least one of the side surface or the bottom surface is arranged. Each through hole 5a is smaller than the disposable diaper 18 so that the disposable diaper 18 does not fall out through the through hole 5a.

[0025] Further, the inner tub 5 is rotatably connected to the rotation drive unit 70. The rotation drive unit 70 is driven under the control of the control device 11 to rotate the inner tub 5 at at least two different rotational speeds. The rotation drive unit 70 includes, as an example, a shaft 13 fixed to the inner tub 5 along the rotation axis of the inner tub 5, a belt 14 engaged with the shaft 13 to rotate the shaft 13, and a motor 12 having a rotation axis to which a gear engaged with the belt 14 is fixed. As a result, it is possible to rotate the inner tub 5 with respect to the outer tub 4 by driving the motor 12 under the control of the control device 11. The rotation axis of the inner tub 5 can be arranged, as an example, along the vertical direction, or along the vertical direction including a direction inclined vertically or obliquely thereto. The rotation drive unit 70 performs, for example, the following operations under the control of the control device 11. The motor 12 rotates the inner tub 5 of the treatment tank 20 to perform a stirring process to separate water from the used disposable diaper 18. Further, after the stirring process, the motor 12 rotates the inner tub 5 from which the treatment liquid 19 has been discharged at a higher speed than during the stirring process to perform a dehydration process.

[0026] The outer tub bottom 15 and the inner tub bottom 17 function as an example of an opening / closing part, and can be opened and closed around a rotation axis with respect to the outer tub 4 and the inner tub 5 by hinge parts 71 and 72, respectively. Below the treatment tank 20, that is, in the lower part of the apparatus main body 3 below the outer tub bottom 15 and the inner tub bottom 17, a take-out part 6 is arranged. The take-out part 6 stores and holds the treated disposable diaper 18 that falls from the inner tub 5 when the outer tub bottom 15 and the inner tub bottom 17 are opened.

[0027] Therefore, the disposable diaper after the weight reduction process can be taken out from the take-out part 6. Inside the take-out part 6, a storage container 7 to which a disposal bag 8 is attached is arranged. The disposal bag 8 is arranged directly below the inner tub bottom 17 so that the disposable diaper 18 after the weight reduction process falls into the disposal bag 8 of the storage container 7.

[0028] [Operation] Next, the weight reduction processing operation of the used diaper processing device 1 under the control of the control device 11 will be described. First, the overall processing flow will be described with reference to FIG. 2. In step S1, the used diaper 18 is directly inserted from the direct insertion door 21 into the direct insertion slot 24a. The used diaper 18 inserted into the direct insertion slot 24a is stored in the inner tank 5 through the opening 27. Next, in step S2, the used diaper 18 is held in the insertion slot 24. If there is space in the insertion slot 24, the used diaper 18 can be held in the insertion slot 24 at any time, not only after step S1 but also before step S1. Next, in step E1, under the control of the control device 11, the treatment liquid 19 that reduces the water absorption function of the superabsorbent polymer contained in the used diaper 18 is supplied from the liquid supply unit 10 into the treatment tank 20 and stored. A chemical that reduces the water absorption function of the superabsorbent polymer may be pre-inserted, and water may be supplied from the liquid supply unit 10 to mix the treatment liquid 19 in the treatment tank 20. Next, in step E2, under the control of the control device 11, the inner tank 5 of the treatment tank 20 is rotated to perform a stirring process to separate water from the used diaper 18. Next, in step E3, under the control of the control device 11, after discharging the liquid accumulated in the outer tank 4 from the liquid discharge part 9, the inner tank 5 is rotated at a higher speed than during the stirring process to dehydrate the used diaper 18. Next, in step E4, when the bottom of the outer tank 15 and the bottom of the inner tank 17 are opened, the used diaper 18 falls into the waste bag 8 installed in the storage container 7. Next, in step D1, the control device 11 checks whether a used disposable diaper is held in the standby slot 24b. To check whether a used disposable diaper is held in the standby slot 24b, for example, a sensor can be arranged in each standby slot 24b for checking. As an example of the sensor, a transmissive sensor can be used. That is, it can be detected whether the light from the light emitting part to the light receiving part of the transmissive sensor is blocked by the disposable diaper 18 placed in the standby slot 24b. If the control device 11 confirms that there is a used disposable diaper 18 in any of the standby slots 24b, the process proceeds to step S3. In step S3, under the control of the control device 11, the cylindrical part drive unit 28 rotates to rotate the cylindrical part 25 clockwise as viewed from above, for example. When the standby slot 24b in which the used disposable diaper 18 is stored comes directly to the insertion position I of the insertion slot 24a, the used disposable diaper 18 drops through the opening 27 and is stored in the treatment tank 20. In step D1, it was detected by the sensors provided in each standby slot 24b whether there is a used disposable diaper 18 in the standby slot 24b at the standby position II. However, a sensor can be arranged at the opening 27, and by rotating the cylindrical part 25 and detecting that the used disposable diaper 18 has dropped, the control device 11 may confirm that the used disposable diaper 18 was present in the standby slot 24b at the standby position II. As an example of the sensor, a transmissive sensor can be used. That is, it can be detected whether the light from the light emitting part to the light receiving part of the transmissive sensor is blocked by the disposable diaper 18 placed in the opening 27. Again, by executing steps E1 to E4, the weight reduction process of the used disposable diaper 18 inserted from the standby slot 24b is executed. Then, step D1 is executed again. In step D1, when the control device 11 confirms that there is no used disposable diaper in all the standby slots 24b at the standby position II, the process proceeds to step S4 and a series of processes ends. Next, the details of each processing operation will be described. Hereinafter, for the sake of convenience of explanation, in the processing flow shown in FIG. 2, after steps S1 and S2 are completed and the used disposable diaper 18 is put into the inner tub 5, the stirring process is being performed in step E2 (FIG. 3), the inner tub 5 is rotated at high speed for dehydration in step E3 (FIG. 4), and the bottom 15 of the outer tub and the bottom 17 of the inner tub are opened in step E4, and the used disposable diaper 18 after the dehydration process is being taken out to the take-out portion 6 (FIG. 5) will be described separately.

[0029] First, in FIG. 3, after a chemical that reduces the water absorption function of the superabsorbent polymer is introduced from the liquid supply unit 10 into the treatment tank 20, the supply of the treatment liquid from the liquid supply unit 10 to the treatment tank 20 is started, and the treatment liquid 19 is stored in the treatment tank 20 (see step E1). As an example of the chemical that reduces the water absorption function of the superabsorbent polymer, those containing metal ions are preferably used, and in particular, calcium chloride or lime containing a divalent metal can be used.

[0030] Next, under the control of the control device 11, the motor 12 is rotationally controlled to rotate the inner tub 5 at the first rotation speed, thereby executing the stirring process (see step E2). Specifically, when the motor 12 rotates at the first rotation speed, the shaft 13 rotates via the belt 14, and the inner tub 5 rotates with respect to the outer tub 4. As a result, the treatment liquid 19 and the used disposable diaper 18 are stirred. In this stirring process, the inner tub 5 does not continue to rotate, but after rotating for a certain period of time (for example, 3 to 5 seconds), it stops, reversely rotates for a certain period of time (for example, 3 to 5 seconds), and stops, or after rotating for a certain period of time (for example, 3 to 5 seconds), it stops and then rotates in the same direction again for a certain period of time (for example, 3 to 5 seconds). Repeating is more favorable for the progress of stirring. When the stirring process continues, the superabsorbent polymer in the used diaper 18 reacts with, for example, divalent metal ions in the chemical agent, causing the water contained in the superabsorbent polymer to separate from the used diaper 18, and the separated water is mixed with the treatment liquid 19. The stirring process here only needs to ensure that the treatment liquid 19 reacts with the superabsorbent polymer of the used diaper 18. It is important to gently stir under the control of the control device 11 so that the used diaper 18 does not separate and disintegrate during the stirring process. Specifically, the first rotation speed is preferably gently stirred at, for example, 40 to 160 rpm.

[0031] Next, the dehydration process of the used diaper 18 will be described with reference to FIG. 4 (see step E3). After discharging the liquid such as the treatment liquid accumulated in the outer tank 4 from the liquid discharge part 9, by rotating the inner tank 5 at a high speed with respect to the outer tank 4 at the second rotation speed, the used diaper 18 can be dehydrated and the weight of the used diaper 18 can be reduced. As an example of the specific second rotation speed, it is preferably dehydrated at a rotation speed of about 800 to 1300 rpm.

[0032] Next, the removal process of the used diaper 18 will be described with reference to FIG. 5 (see step E4). When the outer tank bottom 15 and the inner tank bottom 17 are opened via the hinge parts 71 and 72 in the state where the dehydration is completed, the used diaper 18 drops into the waste bag 8 installed in the storage container 7. When discharging the used diaper 18, it can be discharged by sliding the extraction part 6 laterally with respect to the apparatus main body 3 and taking it out from the apparatus main body 3 and then taking out the waste bag 8 from the storage container 7.

[0033] As described above, according to the first embodiment, when the weight reduction process of the used diaper 18 put into the treatment tank 20 is completed, the used diaper 18 held in the standby slot 24b is automatically put into the treatment tank 20, and the weight reduction process can be continuously carried out. Therefore, it is possible to reduce the weight of the used diaper 18 without the non-operating time of the apparatus. Also, during the weight reduction process, the operator can have the used diaper 18 held by the holding part of the apparatus 1. Specifically, even while the used diaper processing apparatus 1 is in operation, it is possible to put the collected used diaper 18 into the standby slot 24b of the continuous input part 23. Therefore, it is not necessary for the operator to start the next weight reduction process while calculating the timing when the weight reduction process is completed, and it is also possible to reduce the burden on the operator for operating the apparatus 1. That is, it is possible to efficiently perform the weight reduction process of the used diaper 18 without bothering the operator. In addition, since the fiber part remains in the used diaper 18 that has been subjected to the weight reduction process with a chemical agent containing metal ions or the like without being separated and disassembled in the processing tank 20, when discharging the liquid to a sewer pipe or the like, it is not necessary to introduce a device such as filtering out the fiber components of the used diaper 18. Also, it is not necessary for the operator to directly take out the used diaper 18 after processing from above the inner tank, and it is possible to store it in the disposal bag 8 without bothering the operator's hands, thereby reducing the work burden and the sanitary burden on the operator. Therefore, it is possible to perform a series of operations including the weight reduction process of the used diaper 18 and storage in the discharge container without bothering the operator's hands.

[0034] In addition, in the present Embodiment 1, the disposal bag 8 for disposal is installed in the storage container 7, but it is also possible to directly store it in the storage container 7 without installing the disposal bag 8.

[0035] Also, instead of separately preparing the processing liquid 19 in which water and the chemical agent are mixed and directly storing the prepared processing liquid 19 in the processing tank 20, after adding a chemical agent containing metal ions or the like to the processing tank 20, water can be stored to prepare the processing liquid 19 in the processing tank 20.

[0036] Also, instead of using the belt 14 to rotate the inner tank 5, it is also possible to directly connect the rotating shaft of the motor 12 and the inner tank 5 and directly rotate the inner tank 5 by the motor 12.

[0037] [Embodiment 2] Figures 6A to 6C show the device configuration of Embodiment 2 of the present invention. Figure 6A shows a side view of the device, Figure 6B shows a top view of the cylindrical portion 25 and the cylindrical portion storage case 26 with the direct input door 21 and the storage input door 22 omitted, and Figure 6C shows a cross-sectional view taken along line A-A' of Figure 6B.

[0038] The difference from Embodiment 1 is that a winding prevention portion 29 is attached to the lower part of each partition plate 36 of the input slot 24 arranged inside the cylindrical portion 25. The winding prevention portion 29 is composed of, for example, a triangular prism column that extends along the lower edge of each partition plate 36 and has an inclined surface 29a. The inclined surface 29a is preferably arranged at least on the front side in the rotation direction of the cylindrical portion 25. In Figure 6C, when there is no winding prevention portion 29, when the cylindrical portion 25 rotates and drops the used diaper 18 from the standby slot 24b into the treatment tank 20, there is a problem that the used diaper 18 is pinched between the partition plate 36 and the cylindrical portion storage case 26. On the other hand, according to the configuration of Embodiment 2, since there is a winding prevention portion 29 at the lower part of the partition plate 36, when the cylindrical portion 25 rotates, the inclined surface 29a of the winding prevention portion 29 pushes the used diaper 18 upward from the cylindrical portion storage case 26, and the cylindrical portion 25 can rotate without the used diaper 18 being pinched between the partition plate 36 and the cylindrical portion storage case 26, and it is possible to surely and smoothly input the used diaper 18 into the treatment tank 20.

[0039] As described above, according to the present Embodiment 2, in addition to the effects of Embodiment 1, when the cylindrical portion 25 rotates and drops the used diaper 18 from the input slot 24 into the treatment tank 20 in the continuous input portion 23, the used diaper 18 is not pinched between the partition plate 36 and the cylindrical portion storage case 26, and it is possible to efficiently complete the weight reduction process. [Embodiment 3] Figures 7A and 7B show the device configuration of Embodiment 3 of the present invention. Figure 7A shows an enlarged view of the continuous input section 23, showing a state where the removable container 32 is disposed above the input slot 24. Figure 7B shows a state where the removable container 32 is installed on the base 34. The upper end opening of the container 32 can be covered with a lid 31 with a handle 30. The lower part of the container 32 is, for example, divided into a plurality (for example, left and right in Figure 7B) and can be opened by a container lower lid 33 that can be opened and closed by a hinge portion 33a. Further, at the outer end portion on the hinge portion side of each container lower lid 33, a claw 37 that can contact the upper end edge of the side wall of the cylindrical portion 25 forming the input slot 24a is attached. A plurality of used disposable diapers 18 can be stored in the container 32. When the container 32 is positioned above the input slot 24a and pushed downward from above, the claw 37 of the container lower lid 33 catches on the upper end edge of the side wall of the cylindrical portion 25, and the container lower lids 33 each rotate around the hinge portion 33a and both container lower lids 33 open. At this time, the used disposable diapers 18 fall from the lower part of the container 32 and are put into the inner tank 5. By adopting such a device configuration, it becomes possible to put the disposable diaper 18 into the inner tank 5 without the operator directly touching the used disposable diaper 18. Further, the container 32 can be used as a normal trash can by being installed on a base 34 having an outer container shape. At this time, the size of the base 34 is set so that the claw 37 does not contact the upper end edge of the base 34. According to the configuration of Embodiment 3, by installing the container 32 installed on the base 34 in the room where the elderly live, it can be used as a trash can for discarding disposable diapers during excretion assistance. And when performing the weight reduction process, by pushing the container 32 into the standby slot 24, the operator can put the used disposable diaper 18 into the disposable diaper processing device 1 without directly touching the used disposable diaper 18. Thereby, it becomes possible to more efficiently perform the weight reduction process on the used disposable diaper 18.

[0040] According to the above-described Embodiment 3, in addition to the effects of Embodiment 1, the used paper diaper 18 can be put into the diaper processing device 1 by a simpler method, and it is possible to complete the weight reduction process more efficiently and in a shorter time. [Embodiment 4] FIG. 8 shows the device configuration of Embodiment 4 of the present invention. The difference from Embodiment 1 is that a scraping portion 35 is attached to the lower surface of the bottom 15 of the outer tank. When continuously reducing the weight of the used paper diaper 18, as shown in FIG. 8, the processed used paper diaper 18 is deposited biased toward the side where the bottom 15 of the outer tank in the waste bag 8 of the take-out portion 6 opens, and a problem occurs that the volume of the storage container 7 installed at the lower part cannot be effectively used. FIG. 9 shows a state where the deposited processed used paper diaper 18 is scraped by the scraping portion 35, that is, moved to the non-deposited side. The scraping portion 35 attached to the bottom 15 of the outer tank has a structure in which the plate-shaped scraping member 35a can extend out of the storage case 35b in accordance with the opening of the bottom 15 of the outer tank. For example, at the timing when the bottom 15 of the outer tank opens the outer tank 4, a structure can be applied in which the cylinder rod with the scraping member 35a fixed to the tip extends out with respect to the cylinder which is the storage case 35b, causing the scraping member 35a to extend. The timing when the bottom 15 of the outer tank opens the outer tank 4 can be detected by a known opening / closing detection switch installed on the bottom 15 of the outer tank, or the transfer information to step E4 in the control device 11. Not limited to such a cylinder mechanism, a structure using a cam may also be used. As the scraping member 35a of the scraping portion 35 extends with respect to the storage case 35b in accordance with the opening of the bottom 15 of the outer tank 4, it is possible to scrape the deposited used paper diaper 18 to the side opposite to the deposited side in FIG. 9. According to the configuration of the fourth embodiment, when continuously reducing the weight of the used paper diaper 18, the weight reduction process can be performed while scraping out the processed used paper diaper 18. Therefore, the problem that the used paper diaper 18 accumulates on one side of the storage container 7 and the volume of the storage container 7 cannot be effectively utilized can be solved, and it becomes possible to continuously perform the weight reduction process more times. As a result, it is possible to reduce the work burden on the operator.

[0041] As described above, according to the fourth embodiment, in addition to the effects of the first embodiment, it becomes possible to continuously perform the weight reduction process more times, and since the non-operation time of the device due to the storage container 7 being filled can be reduced, it becomes possible to perform the weight reduction process more efficiently.

[0042] Although the embodiments of the present invention have been described above, the above-described embodiments are merely examples for implementing the present invention. Therefore, the present invention is not limited to the above-described embodiments, and it is possible to appropriately modify and implement the above-described embodiments without departing from the gist thereof.

[0043] For example, by appropriately combining any of the various embodiments or modification examples, the respective effects can be achieved. Also, combinations of embodiments, combinations of examples, or combinations of embodiments and examples are possible, and combinations of features from different embodiments or examples are also possible.

Industrial Applicability

[0044] The used diaper processing device according to the above aspect of the present invention can reduce the weight by dehydrating the moisture by reducing the water absorption function of the superabsorbent polymer by mixing the superabsorbent polymer that has absorbed the moisture contained in the excrement with a chemical containing a divalent metal ion or the like, and reducing the amount of moisture contained in the used diaper. Further, since the operator does not need to directly take out the used diaper after processing from the inner tank, the work burden and the burden in terms of hygiene of the operator can be reduced, and it can be used for improving work in a facility for the elderly or a nursery facility where a large amount of diapers are used.
