The upper and lower toilet papers 33 and 34 are drawn out from the roll bodies 35 and 36 toward the toilet bowl 2, overlapped on the way through the roller 37, passed through the guide member 38, and located in the housing 21, which will be described later. It is supplied to the bottom wiping mechanism.

  FIG. 2 shows a simple toilet device with the toilet bowl 2 removed. The bottom wiping mechanism 4 includes a thick plate-like circular body 41. The circular body 41 is rotatably supported in a standing posture by a support shaft 43 installed between left and right side walls 421 (only one is shown) of a U-shaped support base 42. A rubber member 44 as an elastic member having a constant thickness is provided on the entire periphery of the circular body 41 at the center of the outer periphery. Here, the rubber member 44 is separated at a plurality of locations in the circumferential direction (three locations in the present embodiment) with a small gap, and each divided piece of the separated rubber member has a cross-sectional shape as described later. Different from each other.

  The circular body 41 is rotated backward (in the direction of the arrow in FIG. 2) integrally with the support shaft 43 by a drive motor 45 as drive means. With this rotation, toilet paper 33 and 34 drawn out from the roll bodies 35 and 36 by the structure described later are stacked up and down while passing through the roller 37, and through the guide plate 38 as shown by a chain line in FIG. It reaches the rubber member 44 in the upper half of the circular body 41.

  The guide plate 38 is disposed so as to rise obliquely toward the outer periphery of the circular body 41, and has a substantially inverted U-shaped cross section in which both side edges are curved downward. And the width | variety of the top part is gradually narrowed toward the circular body 41. FIG. While the overlapped toilet paper 33 and 34 are drawn out in the direction of the circular body 41 along the lower surface of the guide plate 38, the center portion in the width direction is curved along the cross-sectional shape of the guide plate 38, and the rubber member 44 is moved. Pulled out to cover.

  Link rods 51 extending in the radial direction are arranged at regular intervals in the circumferential direction along both side surfaces (only one is shown in FIG. 2) of the circular body 41, and holding pieces 52 are raised at the outer ends thereof. It is linked so that it can be defeated. The inner end of the link bar 51 is slidably engaged in a cam groove formed on the inner surface of a circular cam plate 53 provided around the support shaft 43.

  The toilet papers 33 and 34 that have reached the outer periphery of the circular body 41 are sandwiched between the outer peripheral surface of the circular body 41 by the holding plate of the holding pieces 52 that have fallen down, and are pulled out as the circular body 41 rotates backward. . When the circular body 41 is rotated approximately half a circumference and the restraining plate 521 is erected, the toilet paper 33 and 34 that has been drawn out is released from the outer peripheral surface, and is separated from the circular body 41 and hangs downward. It is supplied to a cutting machine 6 provided on the base 1 side.

  Toilet paper 33 and 34 that hangs down from circular body 41 and is supplied between guide plates 61 and 62 of cutting machine 6 pass downward between spaced cutting blades 63 and 64. The cutting blade 63 is advanced from the center in the width direction toward both side edges by moving the cutting blade 63 toward the cutting blade 64 so as to overlap each other vertically.

  A support frame 42 that supports the circular body 41 is installed on a lifting platform 71. The elevator 71 is coupled to 72 arranged in a vertical posture, and can be moved up and down as the screw shaft 72 rotates forward and backward. The support shaft 43 that supports the circular body 41 is provided with a 6-axis force sensor (not shown), and detects a force and a moment when wiping the hips, which will be described later. The screw shaft 72 is provided on a moving body (not shown) and can move forward and backward in the horizontal direction.

  FIG. 3 shows a cross section of the user's hip H when using the automatic hip wiping device, and a cross section of the rubber member 44 on the outer periphery of the circular body 41 of the device close to the user's hip H. The rubber member 44 has a triangular cross section that is pointed in the outer peripheral direction and has an apex angle of θh. When wiping the bottom, the circular body 41 provided on the lifting platform 71 (FIG. 2) is raised, and the rubber member 44 The front end of the cross section comes into pressure contact with the surface of the butt H via the toilet paper 33 and 34. In this state, the wiping operation is performed by moving the circular body 41 in the horizontal direction (front and rear direction in FIG. 3).

  A skin care cream that simulates feces is applied to the surface of the buttocks H, and the quality of the buttocks wiping operation is determined based on the degree of removal. In order to determine pass / fail, the wiping rate ηn at the end of the n-th wiping is calculated by the following equation (1).

上式（１）において、Ｍは尻表面に付着したスキンケアクリームの総量であり、ｍiは、i回目の尻拭き動作によってトイレットペーパー３３，３４に付着させられた、すなわち尻表面から拭われたスキンケアクリームの質量である。したがって、Ｎ回（例えば５回）の尻拭き動作終了時にスキンケアクリームが全て尻表面から拭われているとηN＝１となる。

In the above formula (1), M is the total amount of the skin care cream attached to the buttocks surface, and mi is the skin care attached to the toilet paper 33 and 34 by the i-th buttocks wiping operation, that is, the skin care wiped from the buttocks surface. The mass of the cream. Accordingly, η N = 1 when the skin care cream is completely wiped from the buttocks surface at the end of N times (for example, 5 times) buttocks wiping operation.

  FIG. 4 shows an experimental result when the above-described wiping operation is performed with the rubber member 44 of the above-described wiping device in a free state and a triangular cross section having an apex angle θh of 70 °. According to this, even if the wiping operation is performed five times, the static wiping rate ηN is about 0.9, and unwiping remains.

  FIG. 5 shows the experimental results when the above-described wiping operation is performed with the rubber member 44 of the above-described wiping device in a free state with a triangular cross section having an apex angle θh of 150 °. In this case as well, even if the bottom wiping operation is performed five times, the static wiping rate ηN is about 0.9, and unwiping remains.

  Therefore, in this embodiment, as shown in FIG. 6, the rubber member 44 on the outer periphery of the circular body 41 is equally divided into three in the circumferential direction at intervals of 120 °, and the free state of each of the divided pieces 441 to 443 of the rubber member 44. The apex angle θ of the triangular section at 150 was set to 150 °, 110 °, and 70 ° in this order.

  According to such a structure, by rotating the circular body 41 and selectively positioning each of the divided pieces 441 to 443 upward, it is possible to wipe the bottom surface with the divided pieces 441 to 443 having different cross-sectional shapes. Become. In the present embodiment, among the five wiping operations, the first time is performed using the divided piece 441, the second time is performed by rotating the circular body 41 with the divided piece 442, and the remaining three times are performed by further rotating the circular body 41. The bottom piece was wiped with the divided piece 443 by rotating. That is, the vertical angle of the cross section of the rubber member in this case is 150 ° → 110 ° → 70 ° → 70 ° → 70 °. The result is shown in FIG. According to this, the static wiping rate ηN becomes approximately 1 by five wiping operations, and no wiping residue is generated.

  On the other hand, among the five wiping operations, the divided piece 443 is used for the first time, the divided piece 442 is used for the second time, and the remaining three times are used for the divided piece 441, so that the cross-sectional apex angle of the rubber member Is changed from 70 ° → 110 ° → 150 ° → 150 ° → 150 °, as shown in FIG. 8, the static wiping rate ηN after five wiping operations is about 0.9, as shown in FIG. Stays on and causes unwiping.

  From the above, it can be seen that the gap on the butt surface can be efficiently and reliably wiped by gradually decreasing the apex angle θh. Note that the cross-sectional shape of the rubber member is not necessarily an accurate triangular shape.
