Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a novel toilet paper automatic feeder installed in a toilet, which automatically cuts roll-shaped toilet paper to facilitate the user's convenience.

[0002]

[Prior art]

 Conventionally, toilet paper is simply attached to a holder by a shaft, and the user pulls out and cuts the paper by hand each time.

[0003]

[Problems to be solved by the device]

 In the past, the user had to pull out and cut the toilet paper himself, so some people feel this is complicated, and people who use too much force to pull out too much paper and use it wastefully I was there. The present invention has been made for the purpose of facilitating the user's convenience and suppressing the wasteful use of the paper by automatically supplying the toilet paper cut to a predetermined length.

[0004]

[Means for Solving the Problems]

 The present invention provides a support shaft on which toilet paper is mounted, a pair of feed rollers provided below the support shaft in parallel with the support shaft to feed the toilet paper sandwiched by a motor, and a feed roller provided below the feed roller. An automatic toilet paper supply device, comprising: a sheet cutter that is operated by a motor to cut the cut toilet paper; and a tray that is provided below the tray to receive the cut toilet paper. As the sheet cutter, for example, a publicly known mechanism mainly used for facsimiles may be used, as described in Japanese Utility Model Laid-Open No. 3-113796.

[0005]

[Action]

 In the present invention, by pressing a button or the like to turn on the switch, the feed roller rotates to feed the paper, and further, the sheet cutter is operated to cut the paper, and the cut paper is supplied to the lower tray. By controlling the operation of the feed roller and the sheet cutter by the microcomputer, the cutting paper of a predetermined length is automatically supplied only by turning on the switch once or by the detection by the sensor.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front view showing a toilet paper automatic feeding device 1 according to an embodiment of the present invention by cutting a part thereof, FIG. 2 is a longitudinal sectional view of FIG. 1, and FIG. 3 is a control system diagram.

The automatic toilet paper feeder 1 is composed of a main body case 2, a support shaft 3, a feed roller 4, a sheet cutter 5, a tray 6 and the like. A cover 7 for covering the attached toilet paper P is openably and closably attached to the uppermost part of the main body case 2, and a support shaft 3, a feed roller 4, a sheet cutter 5, and a tray 6 are sequentially arranged below the cover 7.

The support shaft 3 has a cantilever structure, and as shown in FIG. 1, the left side is integrally fixed to the main body case 2, and the toilet paper can be inserted from the right side. The feed roller 4 sends a toilet paper sandwiched between a pair of rolls to the sheet cutter 5. When the toilet paper is attached, the lever 12 is operated to widen the gap between the rolls so that the toilet paper can be easily washed. You can thread the paper between them. The feed roller 4 is operated by a motor 8. The sheet cutter 5 has a fixed blade 10 and a swing blade 11, and the motor 9 swings the swing blade 11 to cut the toilet paper. Since the mechanism of such a sheet cutter is known, it will not be described in detail here. The tray 6 is provided with a photoelectric tube sensor 13 to detect the presence or absence of cut paper. As the sensor provided on the tray, any other known sensor may be used. A control unit 14 having a built-in microcomputer is attached to the back side of the body case 2, and an operation button 15 and a cut length selection switch 16 are exposed from the front side of the control unit 14. The power source may be a battery or a household AC power source, but in this embodiment, the battery 17 operates.

When setting the toilet paper, the cover 7 is opened, the toilet paper P is inserted into the support shaft 3, the lever 12 is operated to widen the interval between the feed rollers 4, and the tip of the toilet paper is set to the position of the feed roller 4. After that, the lever 12 is operated again to reduce the distance between the feed rollers 4 and the cover 7 is returned to its original position. When the operation button 15 on the front of the main body case is pressed, the motor 8 is rotated for a predetermined time by computer control and the feed roller 4 feeds the toilet paper downward. When the motor 8 is stopped, the motor 9 rotates for a predetermined time to swing the swing blade 11 of the sheet cutter 5 to cut the toilet paper. The cut toilet paper drops by its own weight and is supplied to the tray 6. When the cut sheet in the tray 6 is used, the photoelectric tube sensor 13 senses it, the feed roller 4 and the sheet cutter 5 operate, and the cut sheet is supplied to the tray 6 again. When the toilet paper runs out, the photoelectric tube sensor 13 detects that the cut paper is not supplied even if the feed roller 4 and the sheet cutter 5 are operated, and the motors 8 and 9 are stopped.

In this embodiment, although a very simple computer control is described, the cut length can be specified by an arbitrary numerical value such as 20 cm, or several cuts can be made at one time. It is also possible to specify the number of sheets to be cut at one time.

[0011]

[Effect of device]

 The toilet paper automatic feeder of the present invention is not only convenient for users because it automatically supplies toilet paper cut to a specified length, but also saves paper resources by suppressing wasteful use of paper. It also contributes to.
