Cutting blades 63 and 64 are provided below the guide plates 61 and 62 in a horizontal posture, and the cutting blades 63 and 64 are curved so that opposing tooth portions 631 and 641 bulge toward each other in the central portion. The tooth portions 631 and 641 are formed with saw teeth. One cutting blade 64 is fixed, and the other cutting blade 63 is integrated with a lifting platform 71 (FIG. 7) on which the circular body 41 is installed. The moving body 74 (FIG. 7) can be operated to advance to a position overlapping the cutting blade 64 in the vertical direction. In FIG. 5, in order to facilitate understanding of the shapes of the cutting blades 63 and 64, these cutting blades 63 and 64 are protruded from the actual position (see FIG. 6).

  FIG. 6 shows a vertical section of the cutting machine 6. A pressing member 65 that moves integrally with the cutting blade 63 and a sandwiching member 66 are disposed above and below the cutting blade 63, respectively, and the sandwiching member 66 is supported by a spring body 661 at the back. On the other hand, a sandwiching member 67 and a pressing member 68 are disposed above and below the cutting blade 64, respectively, and the sandwiching member 67 is supported by a spring body 671 at the back.

  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. When the cutting blade 63 is advanced toward the cutting blade 64 so as to overlap each other vertically, the pressing member 65 comes into contact with the pinching member 67 and the pressing member 68 comes into contact with the pinching member 66 prior to this. 66 and 67 are retracted by a certain amount against the spring force of the spring bodies 661 and 671, and the paper 33 and 34 are sandwiched between the pressing members 65 and 68 and the sandwiching members 66 and 67 in this state. Then, the center of the width direction is formed by the cutting blades 63 and 64 that are advanced so as to overlap at the intermediate position between the papers 33 and 34 that are sandwiched and positioned at the vertical positions by the pressing members 65 and 68 and the sandwiching members 66 and 67. Is cut to the side edges.

  The support frame 42 that supports the circular body 41 is installed on a lifting platform 71 as shown in FIG. FIG. 7 shows a state in which the lifting platform 71 is raised to the upper end. The lifting platform 7 is coupled to a screw shaft 72 that constitutes lifting means arranged in a vertical posture, and can be lifted and lowered as the screw shaft 72 rotates forward and backward. The screw shaft 72 is rotated forward and backward by a drive motor 73. The lifting distance of the lifting platform 71 is detected by a rotary encoder (not shown). Further, 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 butt wiping described later.

The waterproof sheet may be supplied to the circular body 41 by further overlapping the two toilet papers 33 and 34 below. In this way, since the waterproof sheet is in contact with the rubber layer 44, it is possible to prevent the rubber layer 44 from being soiled or adhering to E. coli. In addition, as shown in FIG. 2, the camera 9 is installed toward the toilet paper 33 and 34 that hang down to the cutting machine 6 after the wiping process, and the dirt is detected by imaging the paper surface, and the wiping is completed. Determine whether or not.

  When using the automatic bottom wiping device having the above-described structure, the movable body 74 is moved backward during the addition, so that the bottom wiping mechanism 4 is moved out of the toilet casing 21. After the addition, the movable body 74 is moved forward to cause the wiping mechanism 4 to enter the housing 21. Thereafter, the lifting platform 71 is raised to bring the outer peripheral rubber layer 44 of the circular body 41 into contact with the buttocks surface near the user's anus. When the circular body 41 (that is, the rubber layer 44) is brought into pressure contact with the buttocks surface with a certain pressure or more, the lifting of the lifting platform 71 stops. In this state, the rubber layer 44 is deformed so as to follow the cross section of the buttocks M near the anus as shown in FIG. 6, and the toilet paper 33 and 34 are positioned between the deformed rubber layer 44 and the buttocks surface M1. .

  Subsequently, the process proceeds to the buttocks wiping process, where the moving body 74 is moved forward at a constant speed, and during this time, the outer peripheral rubber layer of the circular body 41 on the buttocks surface based on the force and moment signals obtained from the force sensor. It controls so that the pressing force of 44 becomes a predetermined magnitude. The moving direction of the moving body 74, that is, the wiping direction, may be selected not only in the forward direction but also in forward or backward movement for each gender. As a result, the dirt attached to the buttocks surface is wiped off by the paper. When the movable body is moved forward (or backward) by a certain distance and the wiping process is completed, the lifting platform is lowered. When the circular body 41 is rotated, new toilet paper 33 and 34 are pulled out from the roll bodies 35 and 36 along with the raising / lowering operation of the holding piece 52 described above, and the toilet paper 33 and 34 that has been wiped off are removed. It is droopedly fed into the cutting machine 6. And the cutting blade 63 act | operates and the toilet paper 33 and 34 is cut | disconnected. The separated toilet papers 33 and 34 are dropped and stored in a plastic bag or the like containing filth and discarded.

  Thereafter, the movable body 74 is moved back again to the bottom wiping start position, the lifting platform 71 is raised, and the above-described bottom wiping process is repeated. When the completion of wiping is determined from the captured image of the camera 9, the bottom wiping mechanism 4 is retracted outside the toilet casing 21. The above operation is automatically performed by pressing a start button or the like (not shown) to control the drive motors 45, 73, 76 by the output of the control device. Further, the pressing force of the outer peripheral rubber layer 44 of the circular body 41 to the buttocks surface can be appropriately set and changed with a setting volume or the like.

  In the above embodiment, the toilet paper is an example of a wiping member, and may be a cloth material moistened with a medicine. The circular body does not necessarily have a plate shape, and may be, for example, a roll shape. Moreover, the whole circular body can also be comprised with an elastic material.
