Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an automatic toilet paper supply device that dispenses a roll of toilet paper in the required amount without touching it.

[Conventional technology]

Conventionally, toilet paper is attached to a paper holder inside the toilet, and the required amount is pulled out and cut by hand each time it is needed.

[Problem that the invention attempts to solve]

By the way, in toilets used by an unspecified number of people, such as in hotels and department stores, there is a problem that people are reluctant to touch toilet paper without knowing who touched it, and it is also undesirable from a hygienic standpoint.

The present invention has been made in view of the above problems, and its purpose is to provide an automatic toilet paper supply device that automatically cuts and supplies the required amount of toilet paper without touching the handle. It is on offer.

[Means for solving problems]

In order to achieve the above object, the automatic toilet paper supply device of the present invention comprises: a toilet paper loading section to which toilet paper can be attached and detached; a toilet paper drive system driven by a toilet paper drive motor; and a cutter driven by a cutter motor. , a non-contact switch that is inserted into the power circuit and responds to the non-contact operation and outputs to the self-holding circuit, and the output from the non-contact switch closes the power circuit of the timer and toilet paper drive motor, keeping the power circuit closed from then on. a self-holding circuit that sets the operating time of the toilet paper drive motor; a first timer switch that is normally closed and opens the power supply circuit of the toilet paper drive motor after the set time of the timer has elapsed; A second timer switch that closes the power supply circuit of the cutter motor after the set time elapses, and a first timer switch that is normally closed and opens the input circuit of the self-holding circuit when the cutter starts operating, and closes the input circuit of the self-holding circuit when the cutter ends. The device is provided with at least a limit switch and a second limit switch which is normally open and closes the cutter motor power supply circuit when the cutter starts operating, and opens the cutter motor power supply circuit when the cutter operation ends.

[For production]

In the above configuration, when the non-contact switch is activated by non-contact operation, the output from the non-contact switch activates the self-holding circuit through the normally closed first limit switch,
Keep the timer and toilet paper drive motor power circuits closed. Therefore, when the timer starts operating, the toilet paper drive motor is energized through the normally closed first timer switch, the toilet paper is unrolled and driven via the toilet paper drive thread turn, and when the timer set time has elapsed, the timer starts operating. Then, the first timer switch is opened to stop the toilet paper drive motor and roll out the toilet paper to the required length. At the same time, the normally open second timer switch is closed, the cutter motor is energized, and the cutter starts operating. When the cutter starts operating, the normally closed first limit switch is opened, the closed hold of the self-holding circuit is released, the timer and toilet paper drive motor power circuits are opened, and the first timer switch returns to its original closed state. , second
The timer switch is returned to its original open state, and at the same time the normally open second limit switch is closed. That is, when the first timer switch returns to close, the self-holding circuit opens, and when the second timer switch returns to open, the second limit switch closes, thereby stopping the toilet paper drive motor and operating the cutter motor, respectively. Continued.

Then, the toilet paper is cut by the operation of the cutter, and when the cutter operation is finished, the first U limit switch returns to its original closed state, the second limit switch returns to its original open state, and the cutter motor is stopped to cut the toilet paper. One cycle of supply disconnection is completed, and the device enters the standby position for the next cycle.

The drive rollers 5.5' and 6.6' are driven through the toilet paper drive system consisting of 8.18' and the toilet paper 3 is unrolled (when the set time of the timer 31 has passed, the timer 31 is activated The first timer switch 36 opens and the toilet paper drive motor 14 stops, and the toilet paper 3 is unrolled to the required length and then stopped.Meanwhile, at the same time, the normally open second timer switch 37 closes and the cutter motor +26 is turned on. Electrification is applied, and the lower blade 20b of the cutter 20 starts operating.Lower blade 20b
The first limit switch 27, which is normally closed, starts operating.
is opened, the input of the self-holding circuit relay 35 is cut off, the closed holding of the self-holding contact 35a is released, the power supply circuit of the timer 31 and the toilet paper drive motor 14 is cut off, and the first timer switch 36 is returned to its original closed state. To, the second
The timer switch 37 is returned to its original open state, and at the same time, the normally open second limit switch 28 is closed.

That is, the return of the first timer switch 36 to the closed position is compensated for by the opening of the self-holding contact 35a, and the return to the open position of the second timer switch 37 is compensated for by the closing of the second limit switch 28, thereby stopping the toilet paper drive motor 14 and the cutter. The respective motors 26 continue to operate.

Then, the toilet paper 3 is removed by the operation of the lower blade 20b.
is cut to the required length, thus toilet paper 3
One cycle of supplying and cutting is completed, and the device enters the standby position for the next cycle.

Further, the cutter 20 may be a pair of scissors with movable upper and lower blades.

Further, in the above embodiment, the cut toilet paper 3 hangs down between the lower drive rollers 6 and 6', but the lower drive rollers 6 and 6' are removed and a tray is attached to the lower part of the case 1, and the cut toilet paper 3 is suspended. may be received in a saucer.

FIG. 6 shows another embodiment of the toilet paper drive device. In this embodiment, the supporting shaft 4' of the toilet paper 3 is the outer circumference of a small diameter shaft 4'a inserted into the toilet paper mounting part 2 of the case 1. A plurality of elastic pieces 4'b are provided which press against the inner peripheral surface of the paper core 3a of the toilet paper 3, and one end of the small diameter shaft 4'a is chamfered into an angular shape. Boss portion 39 at the end of the pulley 39 shaft
The holes of the same shape a are removably engaged, and the toothed pulley 39
A toothed belt 16' is wound around a toothed pulley 15 of a toilet paper drive motor 14. Therefore, the toilet paper 3 is directly unrolled and driven by the toilet paper drive motor 14, in which case the drive rollers 5.5', 6.6' of the previous embodiment are not required.

The toilet paper drive system is not limited to transmission using toothed pulleys and toothed belts, but any drive system such as grooved pulley and V-belt transmission, gear transmission, etc. can be selected.
