Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an automatic toilet paper dispensing device, and more particularly to an automatic toilet paper dispensing device that automatically dispenses a predetermined length of toilet paper.

[Conventional technology]

Rolled toilet paper used in washrooms, etc. is usually stored in a paper holder made of metal or plastic. It was cut into pieces and used.

[Problems to be solved by the invention]

However, if the toilet paper is pulled out and used as described above, the following problems arise. That is, when using the toilet paper, the toilet paper must be pulled out and cut, which is time consuming and may not cut properly. Furthermore, if the end of the toilet paper roll is not in a position where the user can pinch it, the user must rotate the toilet paper roll to pull out the toilet paper, which is time consuming. Furthermore, when pulling out the toilet paper, the user may touch parts other than those necessary for use, which poses a hygiene problem. Furthermore, the length of the toilet paper used is not constant, and the amount of toilet paper that is used is unnecessarily drawn out, which is uneconomical.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned conventional problems, and allows users to use toilet paper of a required predetermined length without having to manually pull out and cut the toilet paper. The purpose of the present invention is to provide an automatic toilet paper supply device that can supply toilet paper to people.

[Means to solve the problem]

The present invention provides a feed-out i11N for feeding out rolled toilet paper, and a drive mechanism for driving the feed-out mechanism. a drive motor, a means for controlling the drive motor so that a predetermined length of toilet paper is delivered from the delivery i4"i3 when predetermined delivery conditions are met, and a means for cutting the delivered predetermined length of toilet paper. The above object has been achieved by providing a means for doing so.

[Operation 1] In the present invention, in the toilet vapor automatic supply device, when predetermined delivery conditions are met, a predetermined length of toilet paper is sent out from the delivery mechanism, and the delivered predetermined length of toilet paper is cut. That's what I do. Therefore, when the user uses the toilet paper, the user can use the toilet paper of a required predetermined length without having to manually pull out and cut the toilet paper. Therefore, it does not take much effort to pull out and cut, and there is no chance of failure in cutting. Further, it is possible to eliminate the trouble of pulling out the drawer when the end of the drawer is not long enough to be pinched. Furthermore, since there is no need to touch unused toilet paper when pulling out the toilet paper, it is preferable from a sanitary perspective. Furthermore, the length of the toilet paper to be used is constant and the toilet paper is not drawn out unnecessarily, which improves economic efficiency.

A limit switch on/off signal is input to detect that the cam 72 is at the cutting position. The process controller 14 inputs control signals to the first and second power control sections 98 and 100, which control the power supplied to the spindle motor 12 and the cutting section motor 66, based on these input signals. Control automatic feeding equipment. Further, in the process unit 14, timers TRI and TR2 are stored either built-in or as software for performing a timed operation for determining the control signal. Note that the first photoelectric switch 94 can be installed at an appropriate position near the roll IOA of the toilet paper 10. Further, the second charging switch 96 is provided on the back side of the mounting section 26, as shown in FIG. In addition, the second photoelectric switch 96 is attached to the mounting section 26.
A suitable through-hole or a window made of transparent resin is formed so that the detection light passes through. Further, the limit switch is installed at an appropriate location where it can come into contact with the cam 72. The effects of the embodiment will be explained below. The automatic feed system of the embodiment is controlled according to a routine stored in the process controller 14 as shown in the flowchart of FIG. That is, when the routine shown in the figure starts, first step 110 is executed.
Determine whether the power switch is on. If the determination result is positive, that is, the power switch is turned on, the process proceeds to step 120, where it is determined whether the first photoelectric switch is turned off. If the determination result is positive, that is, the first photoelectric switch 94 is turned off and it is determined that the roll 10A of the toilet vapor 10 is present, the process proceeds to step 130. In step 130, it is determined whether the second photoelectric switch is turned on. If the determination result is positive, that is, the second photoelectric switch is turned on and it is determined that the toilet vapor 10 is not placed on the placing section 26, the process proceeds to step 140. In step 140, timer TR1 in process controller 14 is activated to drive spindle motor 12 for a predetermined time-limited operation time t1. As mentioned above,
The feeding condition for this automatic supply device is when the power switch is on, the first photoelectric switch is off, and the second photoelectric switch is on. If these conditions are not met, the routine returns to the beginning and determination is made until the conditions are met. Next, in step 150, a start signal is input to the first power controller 98 to start the spindle motor 12, and in step 160, it is determined whether or not the timed operation of the timer TR1 has ended. If the determination result is positive, it is determined that the timed operation of the timer TRI has been completed, and the process proceeds to step 170. In step 170, since the timed operation of the timer TRI has been completed, the main shaft motor 12 is stopped. On the other hand, if the determination result is negative, since the timed operation has not yet ended, the process returns to step 150 again and the main shaft motor 12 is rotated. Through the control operations in steps 140 to 170 above,
The main shaft motor 12 rotates by Bt1 during the timed operation set in the timer TR1. This time-limited operation time t1
By rotating the main shaft motor 12 by the amount shown in FIG. In the case of the embodiment, the time limit operation time t1 is, for example, about 10 seconds in which the swing arm 30 makes two reciprocations, and the delivery length is, for example, about 60 an. In this way, the swinging arm 3
When 0 reciprocates twice, the toilet vapor 10 folded into four is placed on the placement section 26. After the spindle motor 12 has stopped, the process proceeds to step 180, and a timer TR2 is activated to drive the cutting motor 66 after a predetermined waiting time t2. Then step 1
At step 90, it is determined whether or not the timed operation of the timer TR2 has been completed. If the determination result is positive, that is, it is determined that the timed operation of the timer TR2 has been completed, the process proceeds to step 200. On the other hand, if the determination result is negative, that is, the timed operation of timer TR2 has not ended, the determination in step 190 is repeated again. In step 200, the cutting section motor 66 is activated. As a result, the cutting section motor 66 will not be started until the timed operation of the timer TR2 is completed, and therefore the cutting section motor 66 will not be started after the rotation of the main shaft motor 12 has completely stopped. Can be done. Next, the process proceeds to step 210, where the limit switch is turned off and the cam 72 is rotated to 1 by the rotation of the cutting section motor 66.
It is determined whether or not the end of rotation is detected. Thereby, it is determined whether or not the operation of the cutting section 58 has ended. If the judgment result is negative, it means that one rotation has not been completed yet.
Returning to step 200 again, the cutting section motor 66 is rotated. On the other hand, if the determination result is negative, it is determined that the cam 72 has completed one rotation and the operation of the cutting section 58 has also ended, so the process proceeds to step 220 and the cutting section motor 66 is stopped. The time chart of the on/off operation of each switch and each motor 12.66 when executing the above routine is shown in the 10th page.
As shown in the figure. As shown in the figure, the main shaft motor 1 is turned on after the power switch is turned on, the first photoelectric switch 94 is turned off, and the second photoelectric switch 96 is turned on.
2 starts. After starting, the main shaft motor 12 operates for a limited operating time t1 and then stops. After the time limit operation time t2 has elapsed from the time of stopping, the cutting section motor 66 rotates while the limit switch is turned from on to off. Toilet vapor is supplied as described above, and when the toilet paper 10 is used up, the roll IOA runs out and the first photoelectric switch 94 is turned on, so that the automatic supply of the toilet paper 10 is stopped. The same applies when the power switch is turned off. By executing the above routine, the toilet paper folded into four with a predetermined length is placed on the placing unit 26 in a usable state at all times. In the above embodiment, the first and second photoelectric switches 94 and 96 are used to automatically supply toilet paper. However, the first photoelectric switch 94 is not used because it is difficult to confirm the presence of toilet paper 10 when there is a small amount of vapor remaining, and only the second photoelectric switch 96 is used. , toilet paper may be automatically supplied. In this case, when the second photoelectric switch 96 remains on for about 20 seconds, it is determined that there is no toilet paper 10 on the roll, and the C source switch is turned off. Thereafter, when the toilet vapor roll IOA is inserted and the power switch is turned on, the second photoelectric switch 96 is turned on and the toilet paper 10 is fed onto the placing section 26. Further, in the above embodiment, the number of reciprocations of the swing arm 30 is controlled by the main shaft motor 12 based on the time limit operation time of the timer TRI.
However, the method of controlling the number of reciprocations of the swing arm 30 is not limited to this. For example, a limit switch is provided at an appropriate position, the limit switch is turned on and off by the swinging arm 30, the number of reciprocations of the swinging arm 30 is counted by turning on and off, and when the counted value reaches a predetermined number of times, the main shaft It is also possible to control the number of reciprocations of the swing arm 30 by stopping the motor 12. In this way, it is possible to eliminate errors in the delivery length of the toilet paper 10 due to the rotation of the timer TR1 and the swing arm 30. Further, in the above embodiments, an automatic toilet paper supply device having a frame shape shown in FIGS. 2 and 3 and a swinging arm having a shape shown in FIG. 5 etc. has been illustrated. The shapes of the frame and the swinging arm are not limited to those shown in the figures, but can be made into appropriate shapes taking into consideration the characteristics such as size, shape, weight, etc. of the component parts. Further, in the above embodiments, the present invention is applied to an automatic toilet paper supply device having a swinging arm as shown in FIG. does not include the swing arm as an essential component, and the present invention can be implemented with an automatic feeding device that does not have the swing arm.
