Thus, the spring 46g generates a biasing force in the rotation direction around the arm rotation shaft 48c, and the roller 46c is pressed against the roller 46a.

  In this state, the upper end portion of the main shaft 42 is passed through the hole 48d of the shaft fixing bracket 48, and the fixing tool 42f is fixed to the shaft fixing bracket 48 with screws. Further, the columns 24 and 25 are respectively screwed to the shaft fixing bracket 48 with screws through screw holes formed in the shaft fixing bracket 48.

  In this way, the feed mechanism 4 and the cutting mechanism 5 are assembled to the mechanism support portion 2, and the structural body shown in FIG. 6A is assembled.

  In use, the belt 6 has a front end portion (Z-axis negative side) of the bag portion 6a sandwiched between the rollers 45a, 45b, 45d and the heater 49 of the roller unit 45, and a rear end portion (Z The positive axis side) is sandwiched between the rollers 46 a and 46 c of the roller unit 46. Further, the lower end portion of the band body is fitted into the guide 21a of the support substrate 21, and the hooks 31a and 31b are hooked inside the upper end portion (Y axis positive side) of the band body 6.

  FIG. 6A and FIG. 6B are perspective views showing the structural body in a state where the belt body 6 is set on the mechanism support portion 2. 6 (a) and 6 (b), the guides 33a and 33b and the shaft fixing brackets 47 and 48 are transparently shown for convenience.

  In the state of FIG. 6A, the bag portion 6a is positioned at the center position in the Z-axis direction at a substantially intermediate position between the rollers 45a and 46a. Further, the hooks 31a and 31b are hooked on the upper portion of the substantially central position in the Z-axis direction of the bag portion 6a.

  When opening the upper part of the bag part 6a, in the state shown in FIG. 6A, the rear side (Z-axis positive side) of the bag part 6a and the front side (Z-axis negative side) of the bag part 6a are respectively It is sent forward (Z-axis negative direction) and backward (Z-axis positive direction). That is, by driving the motors 43 and 44 (see FIG. 5A), the rollers 45a and 45b of the roller unit 45 and the roller 46a of the roller unit 46 are rotated in opposite directions. As a result, the rear upper end of the bag portion 6a is fed in the negative Z-axis direction by the rear (Z-axis positive side) roller unit 46, and the bag portion 6a is transferred by the front (Z-axis negative side) roller unit 45. Is forwarded in the positive direction of the Z-axis. Furthermore, when the motors 39a and 39b (see FIG. 5A) are driven, the hooks 31a and 31b are moved away from each other. Thereby, as shown in FIG.6 (b), the upper part of the bag part 6a of the strip | belt body 6 hooked on the hooks 31a and 31b is expanded greatly.

  6A, the front end (Z-axis negative side) of the bag portion 6a is positioned at the position of the roller unit 45, but actually, it is slightly more than the position of the roller unit 45. The front end (Z-axis negative side) of the bag portion 6a is positioned at a position advanced to the Z-axis negative side. Thereby, even if the belt body 6 is sent in the positive direction of the Z-axis, the contact between the roller unit 45 and the front end (Z-axis negative side) of the bag portion 6a is not released, and the opening of the bag portion 6a is smoothly advanced. be able to.

  FIG. 7 is a perspective view showing the toilet seat device 100 with the toilet seat 7 mounted thereon.

  The toilet seat 7 is placed on an outer frame 8 described later (see FIG. 9). The toilet seat 7 has a rectangular shape in a top view, and has a drop opening 7a at the center. At the edge of the drop opening 7a, a collar portion 7b for preventing the excrement from scattering is formed. As shown in the drawing, the drop opening 7a has a teardrop shape in which the front side (Z-axis negative side) is slightly swollen in a top view. In the present embodiment, by controlling both of the roller units 45 and 46 of the feed mechanism 4, the opening of the bag portion 6 a is adjusted to be larger than the drop opening 7 a of the toilet seat 7.

  FIG. 8 is a top view showing a state in which the bag portion 6a of the band 6 is opened. In FIG. 8, for convenience, the toilet seat 7 and the drop opening 7a are indicated by a one-dot chain line.

  As described above, in this embodiment, the bag portion 6a is fed in the negative Z-axis direction by the roller unit 46 on the rear side (Z-axis positive side), and the bag unit 45 is fed by the roller unit 45 on the front side (Z-axis negative side). The part 6a is sent in the positive direction of the Z axis. Thereby, the bag part 6a can be bent and the hooks 31a and 31b can pull the bag part 6a. Here, the feed amounts of the roller unit 45 and the roller unit 46 are set to be substantially the same. Furthermore, substantially simultaneously with the timing when the bag portion 6a is sent by the roller units 45 and 46, the hooks 31a and 31b are moved away from each other, and the bag portion 6a of the band 6 is pulled in the X-axis direction. Thereby, as shown in the drawing, the upper opening of the bag portion 6a has a substantially elliptical shape when viewed from above, and is larger than the drop opening 7a of the toilet seat 7. Thereby, excrement, filth, etc. can be appropriately accommodated in the bag part 6a.

  FIG. 9 is a schematic diagram showing an overview of the toilet seat device 100 as a whole. FIG. 9 is an internal perspective view when the toilet seat device 100 is viewed in the positive direction of the X axis, and only the outer frame 8 is shown in a sectional view.

  As shown in FIG. 9, the base 1 is installed on a base portion 8 a formed integrally with the outer frame 8, and the toilet seat 7 is fitted into the upper portion of the outer frame 8. On the upper surface of the outer frame 8, a step 8b for placing the toilet seat 7 is provided, and an opening 8c is provided inside the step. In addition to this, the outer frame 8 is provided with a band housing part 200, a bag discarding part 300, and a circuit housing part 400. The band body accommodating part 200 is a space for housing the band body 6, and for example, the band body 6 is housed so as to be wound around a cylindrical core. The bag disposal unit 300 is a space in which used bag units 6a are stored, and a takeout port is provided so that the user can take out the bag unit 6a to the outside when a predetermined amount of the bag unit 6a is collected. . The circuit housing unit 400 houses a circuit board, a power supply unit, and the like on which a circuit unit 500 (see FIG. 13) for controlling each mechanism unit of the toilet seat device 100 is mounted.

In a state where the base 1 is installed on the base portion 8 a, the shaft fixing brackets 47 and 48 are at a position lower than the top surface of the outer frame 8. Further, the upper end of the belt body 6 is positioned below the lower end of the collar portion 7 b of the toilet seat 7. That is, a slight gap is provided in the vertical direction (Y-axis direction) between the belt body 6 and the collar portion 7b of the toilet seat 7, thereby enabling the belt body 6 to be fed in the Z-axis direction. Yes. Furthermore, in order to properly position the drop opening 7a of the toilet seat 7 in the opening of the bag portion 6a of the band 6, the size of the drop opening 7a is larger than the size of the opening of the bag 6a of the band 6 as described above. Set a little smaller. Therefore, there is a slightly large gap between the opening of the bag portion 6a of the belt body 6 and the collar portion 7b of the toilet seat 7 in the front-rear and left-right directions (X-axis direction and Z-axis direction).

  As described above, since there is a gap between the belt body 6 and the toilet seat 7, there is a possibility that excrement is scattered from the gap and reaches the member of the toilet seat device 100 outside the belt body 6. Therefore, in the present embodiment, by raising the mechanism support portion 2, the gap between the belt body 6 and the toilet seat 7 is reduced, and the scattering of excrement into the toilet seat device 100 is suppressed.

  10A is a side view of the toilet seat device 100 in a state before the mechanism support portion 2 is lifted, as viewed from the Z-axis positive side, and FIG. 10B is a state after the mechanism support portion 2 is lifted. It is the side view which looked at the toilet seat apparatus 100 from the Z-axis positive side. In FIGS. 10A and 10B, the inside of the support substrate 21 is shown to be seen through. In FIGS. 10A and 10B, the motor 44 (see FIG. 5A) is not shown.

  When the worm 29b is rotated by driving the motor 29 from the state shown in FIG. 10A, the worm wheel 28 meshed with the worm 29b is rotated. As the worm wheel 28 rotates, the screw shaft 27 press-fitted into the worm wheel 28 rotates, and an upward force (Y-axis positive direction) is applied to the screw receiver 26. Since the support substrate 21 is guided in the vertical direction by the guides 12 to 15, the support substrate 21 is raised in the Y-axis positive direction by the force applied to the screw receiver 26. Thereby, the base 1 and the support substrate 21 are separated from each other, and the gap between the toilet seat 7 and the shaft fixing brackets 47 and 48 is reduced as shown in FIG. Since the screw shaft 27, the worm wheel 28, and the motor 29 are fixed to the base 1, they do not rise as the support substrate 21 rises.

  In the present embodiment, the support substrate 21 is raised until the fixture 51 b of the blade feed shaft 51 provided on the upper portions of the shaft fixing brackets 47 and 48 comes into contact with the toilet seat 7. Thereby, the clearance gap between the belt | band | zone body 6 and the toilet seat 7 is shortened, and the stain | pollution | contamination of the member of the toilet seat apparatus 100 can be suppressed.

  Further, when the support substrate 21 is raised, as shown in FIG. 8, since the bag portion 6a of the belt body 6 is widened in advance, the collar portion 7b of the toilet seat 7 is properly fitted into the belt body 6. Can be included.

  In this way, the belt body 6 is spread and set at the lower part of the toilet seat 7. In this state, excrement etc. are dropped into the drop opening 7a, and the dropped excrement etc. are accommodated in the band 6.

  FIG. 11A and FIG. 11B are perspective views showing the structure in a state where the excrement is accommodated in the bag portion 6 a of the band 6. In FIGS. 11A and 11B, the toilet seat 7 is omitted for convenience. In addition, when accommodation of excrement etc. is complete | finished, for example, according to the operation input from a user, the support substrate 21 will fall until it mounts on the base 1. FIG. FIG. 11A and FIG. 11B show a state after the support substrate 21 is lowered.

  When the accommodation of the excrement is completed, first, the hooks 31a and 31b are returned to the center position as shown in FIG. Thereafter, with the heater 49 being heated, the roller units 45 and 46 are driven, and the belt 6 is fed in the negative Z-axis direction. Since the upper part of the band 6 is not sealed and has a gap 6d, the hooks 31a and 31b continue to engage with the upper part of the bag part 6a even if the band 6 is moved in the Z-axis direction. For this reason, it is not necessary to engage the hooks 31a and 31b with the upper part of the bag part 6a every time the belt body 6 is sent, and the structure of the opening mechanism 3 can be simplified.

With the heater 49 heated, the belt 6 is sent in the negative Z-axis direction, whereby the coating inside the belt 6 is welded and the bag portion 6a of the belt 6 is sealed. In addition, in order to weld the inner side of the strip 6 appropriately, the feeding speed of the strip 6 is adjusted slower. Thereby, as shown in FIG.11 (b), the strip | belt body 6 is sent until the connection part 6b of the strip | belt body 6 is located in the position of the cutter 53a.

  A minute optical sensor (not shown) is provided at the upper surface position of the support substrate 21 immediately below the cutter 53a. For example, a photocoupler is used as the optical sensor, and detects the presence or absence of an obstacle at the front position. The optical sensor is disposed so as to face the lower end portion of the band 6 from the X-axis negative side. The detection signal of the optical sensor changes at the timing when the notch 6c is positioned at the front position of the optical sensor. The control unit detects the position of the bag 6a based on the change in the detection signal from the optical sensor, and stops the feeding of the band 6. Thereafter, the control unit drives the cutter 53a from the upper side to the lower side to cut the connecting portion 6b of the band 6. When the cutter 53a is moved to the lowermost position, the cutter 53a reaches the notch 6c of the band 6.

  FIG. 12A is a side view of the toilet seat apparatus 100 before cutting the band body 6, and FIG. 12B is a side view of the toilet seat apparatus 100 after cutting the band body 6. In FIGS. 12A and 12B, the inside of the support substrate 21 is shown to be seen through.

  When it is detected by the optical sensor that the notch 6c is positioned at the cutting position, the blade 52 is rotated by driving the motor 52 in the state shown in FIG. The holder 53b is sent in the negative Y-axis direction. By sending the cutter holder 53b in the negative Y-axis direction, the bag portion 6a of the band 6 is cut by the cutter 53a. At this time, since the notch 6c (see FIG. 11B) is provided at the lower end portion of the connecting portion 6b of the belt body 6, the cutter 53a is notched when the cutter holder 53b is lowered to the lower end. 6c is reached and the bag portion 6a is cut off. Since the connecting portion 6b is fixed with a predetermined width, the inside of the separated bag portion 6a is not exposed to the outside from the cut end even if the belt body 6 is cut. The inside of the bag portion 6a for housing the container is not exposed to the outside from the cut end.

  Thus, when the bag part 6a is cut off, the cut bag part 6a is guided to the bag discarding part 300 shown in FIG. The used bag portion 6a stored in the bag discarding portion 300 is taken out and discarded by the user at a predetermined timing. Then, in the same manner as described above, the next bag portion 6a is opened by the opening mechanism 3, and the mechanism support portion 2 is raised and set to the next use state.

  FIG. 13 is a block diagram illustrating a configuration of the toilet seat apparatus 100.

  As illustrated in FIG. 13, the circuit unit 500 includes a CPU 501, a memory 502, and an interface 503. The CPU 501 controls each unit in accordance with a program held in the memory 502. The CPU 501 outputs a control signal to each unit via the interface 503 and receives a signal from each unit via the interface 503. The sensor unit 601 includes various sensors arranged in the toilet seat apparatus 100 in addition to the optical sensors described above. The input unit 602 includes, for example, a remote controller that is wired to the circuit unit 500.

  FIG. 14 is a flowchart illustrating a control example of the toilet seat apparatus 100. The control shown in FIG. 14 is performed by the CPU 501 in FIG.

Referring to FIG. 14, CPU 501 determines whether or not the defecation operation is started (S11). The start of the defecation operation is determined based on, for example, whether or not a button operation for starting the defecation operation has been performed on the input unit 602. When defecation is not started (S11
: NO), the CPU 501 determines whether or not the power is turned off (S12). When the power is not turned off (S12: NO), the CPU 501 returns the process to S11. When the power is turned off (S12: YES), the CPU 501 ends the process.

  When the defecation operation is started (S11: YES), the CPU 501 drives the roller units 45 and 46 to move the hooks 31a and 31b of the opening mechanism 3 away from each other while approaching the front and rear of the bag portion 6a (S13). ). Note that the amount of movement of the hooks 31a and 31b is adjusted by the number of steps of the motors 39a and 39b, for example.

  When the bag portion 6a is thus opened, the CPU 501 next drives the motor 29 to raise the support substrate 21 (S14). The amount of movement of the support substrate 21 is adjusted by the number of steps of the motor 29.

  Then, the CPU 501 determines whether or not the defecation operation is finished (S15). The end of the defecation operation is determined by, for example, whether or not a button operation for ending the defecation operation has been performed on the input unit 602, similarly to the start of the defecation operation. When the defecation operation ends (S15: YES), the CPU 501 drives the motor 29 to lower the support substrate 21, and places the support substrate 21 on the base 1 (S16). Thereafter, the CPU 501 drives the heater 49 and starts sealing the upper portion of the bag portion 6a (S17). The upper part of the bag part 6a is heated by the heater 49, and the upper part of the bag part 6a is welded. In this state, the CPU 501 drives the roller units 45 and 46 in the same direction and sends the belt 6 in the forward direction (Z-axis negative direction) (S18). Thereby, the upper part of the bag part 6a is sealed. Then, the CPU 501 determines whether or not the notch 6c is positioned at the cutting position (S19). Specifically, as described above, it is determined whether or not the notch 6c is positioned at the cutting position based on the change in the detection signal from the optical sensor. When the cutout 6c is not positioned at the cutting position (S19: NO), the CPU 501 returns the process to S18 and moves the belt 6 forward (Z-axis negative direction) until the cutout 6c is positioned at the cutting position. Repeat the process sent to.

  When the notch 6c is positioned at the cutting position (S19: YES), the CPU 501 stops the heater 49 to finish sealing the upper portion of the bag portion 6a (S20), and stops the roller units 45 and 46 to stop the belt body. 6 is terminated (S21). Thereby, the next bag part 6a is located in the position directly under the dropping port 7a. Moreover, the center part of the connection part 6b between the bag part 6a in which the excrement is sealed and the next bag part 6a is positioned at a position directly below the cutter 53a.

  Thereafter, the CPU 501 drives the cutter unit 53 to cut the bag portion 6a (S22). Thereby, the bag part 6a in which the excrement is sealed is cut off from the band 6 and accommodated in the bag discarding part 300 (see FIG. 9). Then, the CPU 501 returns the process to S11 and determines whether or not the next defecation operation is started (S11). When the defecation operation is started (S11: YES), the CPU 501 executes the next accommodation process. If the defecation operation is not started (S11: NO) and the power is turned off (S12: YES), the CPU 501 ends the process.

<Effect of embodiment>
As described above, according to the present embodiment, the feeding mechanism 4 is driven to position the bag portion 6a below the drop opening 7a of the toilet seat 7, and the opening mechanism 3 is driven to open the upper portion of the bag portion 6a. . Thereby, excrement, filth, etc. can be dropped smoothly and surely to each bag part 6a of belt 6.

Further, according to the present embodiment, the hook 31a is driven while the roller units 45 and 46 are driven.
, 31b is driven to open the upper portion of the bag portion 6a, so that the bag portion 6a can be opened smoothly and quickly.

  Further, according to the present embodiment, the hooks 31a and 31b continue to engage with the upper portion of the bag portion 6a even when the belt 6 is moved in the horizontal direction. Does not need to be engaged with the upper portion of the bag portion 6a. Therefore, the configuration of the opening mechanism 3 can be simplified.

  Moreover, according to this Embodiment, since the bag part 6a is opened so that the magnitude | size of the upper opening of the bag part 6a may become larger than the dropping opening 7a of the toilet seat 7, the excretion dropped from the dropping opening 7a Objects, filth, etc. do not come off from the opening of the bag part 6a, and excrement, filth, etc. can be more reliably stored in the bag part 6a.

<Example of change>
While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made to the configuration example of the present invention.

  For example, in the above embodiment, as shown in FIG. 8, the feed amount of the roller unit 45 on the front side (Z-axis negative side) is set so that the shape of the opening at the top of the bag portion 6a is substantially elliptical. The feed amount of the roller unit 46 on the rear side (Z-axis positive side) was set to be substantially the same. However, when the upper portion of the bag portion 6a is opened, the feed amount of the front roller unit 45 and the feed amount of the rear roller unit 46 may be set to be different from each other.

  For example, as shown in FIG. 15A, the shape of the opening of the bag portion 6a is such that the front side (Z-axis negative side) is wider in the X-axis direction than the rear side (Z-axis positive side). The feed amount of the roller units 45 and 46 may be set. That is, the shape of the drop opening 7a of the toilet seat 7 has a shape in which the front side (Z-axis negative side) is slightly swollen, so that the feed amount of the rear roller unit 46 is the front side so that the shape of the opening approaches this shape. It may be set to be smaller than the feed amount of the roller unit 45.

  Further, as shown in FIG. 15 (b), when the rear side of the drop opening 7a of the toilet seat 7 is narrow, only the front roller unit 45 is moved without driving the rear roller unit 46. It may be driven to return only the front side of the band 6 and mainly open the front side of the bag portion 6a. In this case, it is desirable to shift the arrangement position of the hooks 31a and 31b from the central position between the roller units 45 and 46 to the Z axis negative side so that the front side of the bag portion 6a is opened by the hooks 31a and 31b.

  Thus, the return amount of the front roller unit 45 and the feed amount of the rear roller unit 46 do not necessarily have to be the same, and the shape of the upper opening of the bag portion 6a is changed to the shape of the drop opening 7a of the toilet seat 7. The return amount and the feed amount may be different as long as they can be approximated. By doing so, excrement, filth and the like dropped from the drop opening 7a can be more reliably stored in the bag 6a without detaching from the opening of the bag 6a. In addition, since the feeding mechanisms (roller units 45 and 46) are provided on both the front side and the rear side, the shape of the opening of the bag portion 6a can be made closer to the shape of the dropping port 7a more smoothly. Further, if the drop opening 7a has another shape, the return amount of the front roller unit 45 and the feed amount of the rear roller unit 46 are set so as to approach the shape. Further, the hooks 31a and 31b in the Z-axis direction can be appropriately changed.

In the embodiment described above, the drop opening 7a of the toilet seat 7 has a shape in which the front side (Z-axis negative side) is slightly swollen, but the drop opening 7a of the toilet seat 7 is substantially elliptical as shown in FIG. In case, bag part 6
The front roller unit 45 and the rear roller unit 46 may be driven by making the return amount and the feed amount substantially the same so that the front side and the rear side of a are close to each other. Thereby, the shape of the opening of the bag portion 6a can be brought close to a shape symmetric with respect to the feeding direction of the band 6. Therefore, as shown in FIG. 16, when the shape of the drop opening 7a is symmetrical to the feeding direction of the band 6, the opening amount of the bag portion 6a is made by making the return amount and the feeding amount substantially the same. Can be brought close to the shape of the drop opening 7a.

  Further, the front roller unit 45 and the rear roller unit 46 do not necessarily have to be driven at the same time. The timing at which the belt body 6 is returned by the front roller unit 45 and the belt body 6 is sent by the rear roller unit 46. The timing may be shifted. Furthermore, the return speed of the front roller unit 45 and the feed speed of the rear roller unit 46 may be different, and these speeds can smoothly open the bag portion 6a as the hooks 31a and 31b are separated. It only has to be set to speed.

  In the above-described embodiment, the hooks 31a and 31b are driven while the front roller unit 45 and the rear roller unit 46 are driven to open the upper portion of the bag portion 6a. After driving the roller unit 46 on the rear side, the hooks 31a and 31b may be driven to open the upper portion of the bag portion 6a. However, when the hooks 31a and 31b are driven while the front roller unit 45 and the rear roller unit 46 are driven as in the above embodiment, the upper portion of the bag portion 6a is opened more smoothly and quickly. Can be made.

  Moreover, in the said embodiment, after the bag part 6a was positioned in the position under the dropping opening 7a of the toilet seat 7, the upper part of the bag part 6a was opened by the opening mechanism 3 at the time of the start of the defecation operation. Before the start of the operation, the upper portion of the bag portion 6a may be opened in advance. For example, the upper portion of the bag portion 6a may be opened while the bag portion 6a for storing the excrement is then sent toward a position below the dropping port 7a of the toilet seat 7.

  In this case, driving of the opening mechanism 3 is started at a timing before the bag portion 6a is sent to a position immediately below the drop opening 7a. From this timing, the feed speeds of the roller units 45 and 46 are adjusted so that the feed speed of the rear roller unit 46 is faster than the feed speed of the front roller unit 45. As a result, slack is generated in the upper portion of the bag portion 6a, and the upper portion of the bag portion 6a can be opened by the opening mechanism 3. The feed speeds of the roller units 45 and 46 may be adjusted so that the shape of the opening of the bag portion 6a approaches the shape of the drop opening 7a.

  Moreover, in the said embodiment, although the roller units 45 and 46 were provided in the position before and behind the bag part 6a, for example, a roller unit may be provided only in the front side. Further, the number of roller units is not limited to this, and three or more roller units may be used.

  Moreover, in the said embodiment, the collar part 7b of the toilet seat 7 was fitted by the upper part of the bag part 6a of the strip | belt body 6 by raising the mechanism support part 2, For example, the excretion in the toilet seat apparatus 100 In the case where such scattering is suppressed by another configuration, the mechanism for raising the mechanism support portion 2 may be omitted. Further, the opening of the bag portion 6 a of the belt body 6 is not necessarily larger than the dropping port 7 a of the toilet seat 7.

  Moreover, in the said embodiment, although the thing made from paper was used for the strip | belt body 6, the thing of another material may be used.

  Moreover, in the said embodiment, although the strip | belt body 6 was cut | disconnected by the cutter unit 53, the strip | belt body 6 may be cut | disconnected by the other means. For example, the band 6 may be cut by the heat of the heater.

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
