[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the configuration of the present invention will be described in detail based on embodiments shown in the drawings.
[0016]
1 to 10 show an embodiment of a roll paper supply device 1 of the present invention. As shown in FIG. 1, the roll paper supply apparatus 1 includes a holder body 3 that rotatably supports a roll paper 2, and a support 4 that rotatably supports one end 4 in a direction in contact with and away from the roll paper 2. And a lid portion 6 whose side abuts on the roll paper 2. The lid 6 contains a feed roller 7 that feeds the roll paper 2 and a drive unit 8 that rotationally drives the feed roller 7. The feed roller 7 is disposed on the other end 5 side from the center of the roll paper 2. Furthermore, the roll paper supply device 1 includes a control unit 19 that controls the drive unit 8 and static elimination members 28 and 29 provided in the vicinity of the control unit 19 as shown in FIGS. 2 and 3. I have to.
[0017]
The electricity removing members 28 and 29 are composed of a first static electricity removing member 28 that prevents static electricity from the operator and a second static electricity removing member 29 that prevents static electricity from the roll paper 2. It is made to become. Therefore, adverse effects from both static electricity from the operator and static electricity from the roll paper 2 can be eliminated.
[0018]
In the roll paper supply device 1, the lid 6 includes a feed roller 7, a drive unit 8, a control unit 19 that controls the drive unit 8, and a power supply 12 that supplies the drive unit 8 and the control unit 19. Has been. The roll paper 2 is toilet paper. And the cover part 6 is good also as a shape replaceable with the lid | cover of the existing manual paper-winding machine. The holder body 3 can be the same as that of the current manual type paper winding machine.
[0019]
The feed roller 7 is made of rubber in the present embodiment, and is provided at two positions on the same axis. The shaft 9 of the feed roller 7 is rotatably supported by a groove 10 in the casing of the lid portion 6. As shown in FIG. 6, the installation position of the feed roller 7 is farther from the rotation center 11 of the lid 6 to the upper end portion (AA point) of the minimum diameter of the roll paper 2 and from the rotation center of the lid 6 to the roll paper. The range X is closer to the other end 5 side end (point BB) of the smallest diameter of 2. Thereby, the feed roller 7 can always contact the roll paper 2 regardless of the amount of the roll paper 2. Moreover, since the contact is made with a uniform pressure, the conveying force can be made constant. The feed roller 7 is not limited to rubber. For example, a ceramic roller, a metal roller with unevenness, or the like may be used as long as the roll paper 2 can be reliably fed out.
[0020]
A dry battery is used as the power source 12. Therefore, since the cover part 6 becomes heavier enough, the pad pressure to the roll paper 2 can be increased and the supply of the roll paper 2 can be made more reliable. The lid 6 is formed with a battery box 30 for accommodating the power supply 12.
[0021]
A multistage reduction gear is used as the reduction mechanism 14 of the drive unit 8. The speed reduction mechanism 14 connects the pinion 15 of the motor 13 and the pinion 16 provided on the feed roller 7 by a gear train. In the figure, reference numeral 20 denotes a base plate for suppressing the gear train. 4 is the same as the pinion 15 and is shown for easy understanding of the relationship with the one-way clutch 17.
[0022]
In this gear train, as shown in FIG. 4, a one-way clutch 17 that transmits the rotation of the drive motor 13 to the feed roller 7 is used. As shown in FIG. 8, the one-way clutch 17 includes a ratchet 31 and a ratchet gear 32, and the ratchet 31 and the ratchet gear 32 are rotatably arranged on a shaft 100 provided on the lid 6. As shown in FIG. 4, the ratchet 31 is provided with an output gear 173 integrally with the ratchet 31, and transmits rotation in a predetermined direction to the speed reduction mechanism 14.
[0023]
The ratchet 31 is formed with a plurality of elastic arm portions 31a (three in the present embodiment) and engaging teeth 31b at the tips of the respective elastic arm portions 31a. An engaging portion 32a having a recess 32b that engages repellently is formed.
[0024]
When the one-way clutch 17 transmits the drive of the motor 13 to the feed roller 7, the rotation of the motor 13 is transmitted to the ratchet gear 31 via the pinion 15, and this rotation is further transmitted to the engagement portion 32a. It is transmitted to the engaging teeth 31b of the ratchet 31 engaged with the recess 32b. The rotation of the ratchet 31 is transmitted to the output gear 173 and is transmitted in turn to the speed reduction mechanism 14 disposed thereafter.
[0025]
On the other hand, when the motor 13 is stopped, that is, when the roll paper 2 is manually pulled and the feed roller 7 is rotated, the engaging teeth 31b are disengaged from the recesses 32b by the elastic action of the elastic arm portions 31a. The rotation from the feed roller 7 is not transmitted to the ratchet gear 32 side. That is, since the rotation is not transmitted to the motor 13, the feed roller 7 can be easily rotated because it is not affected by the detent torque of the motor 13. Thereby, even when the power is not turned on, the roll paper 2 can be easily pulled out manually.
[0026]
In the present embodiment, as shown in FIG. 4, the one-way clutch 17 is provided closest to the motor 13 in the gear train from the motor 13 to the feed roller 7. For this reason, it is necessary to rotate a large number of gears during manual operation, so that a slightly large torque is applied. However, when the motor 13 is driven, the force applied to the one-way clutch 17 is small, so that a low proof strength can be employed.
[0027]
Moreover, as shown in FIG. 3, the gear train of the speed reduction mechanism 14 is arranged in the horizontal direction. Thereby, it can prevent that the cover part 6 becomes high.
[0028]
Further, a cutter 18 for cutting the fed roll paper 2 is provided at the other end 5 of the lid 6. This cutter 18 is made of rubber. Therefore, the roll paper can be easily cut using the cutter.
[0029]
Then, as shown in FIG. 5, the control unit 19 is executed by turning on at least two of the first and second switches 21 and 22 and one of the first and second switches 21 and 22. A first timer circuit 23 and a second timer circuit 24 as timers for setting the operation time of the operation, an AND gate 25 that operates when both the first and second switches 21 and 22 are turned on, and a first timer circuit 23, and a control circuit 26 for controlling the drive motor 13 as the drive unit 8 based on an output signal from the second timer circuit 24 or the AND gate 25. When only the first switch 21 is turned on, the roll paper 2 is fed out by a predetermined length, and when only the second switch 22 is turned on, the roll paper 2 has a predetermined length different from that when the first switch 21 is turned on. In the embodiment, the roll paper 2 having a shorter length is sent out, and when the first and second switches 21 and 22 are turned on, a length other than the above-described length is sent out. In the present embodiment, the roll paper 2 is continuously conveyed while the first switch 21 and the second switch 22 are on. The control unit 19 includes a constant voltage circuit 27 that controls the voltage from the power supply 12.
[0030]
The first static electricity removing member 28 prevents static electricity from being charged by the operator from adversely affecting the control circuit 26. The first static electricity removing member 28 is provided by wire springs provided on the respective sides of the first switch 21 and the second switch 22. Become. The static electricity removing member 28 is grounded to the control unit 19 or the GND of the power source 12 by being directly attached to the substrate.
[0031]
A protective sheet 36 is provided above the switches 21 and 22 as shown in FIG. The protective sheet 36 is a resin film. The user can push down the switches 21 and 22 by pressing down the protective sheet 36 from above to deform it (two-dot chain lines in the figure). The first static eliminating member 28 is provided slightly higher than the switches 21 and 22. As a result, when the protective sheet 36 is pushed down, the first static electricity removing member 28 is brought into contact without impairing the operational feeling of the switch. The static electricity from the user flows into the first static electricity removing member 28 having a low resistance, and the first static electricity removing member 28 acts as a lightning rod against the static electricity from the operator, so that the controller 19 malfunctions due to the static electricity. Can be prevented.
[0032]
The second static electricity removing member 29 prevents static electricity generated from the roll paper 2 from adversely affecting the control circuit 26 and is provided from the lower part of the lid 6 toward the roll paper 2. Consists of wire springs. This static electricity removing member 29 is also grounded to the GND of the control unit 19.
[0033]
As shown in FIG. 10, the second static electricity removing member 29 includes a contact portion 33 protruding toward the roll paper 2 and a connection portion 34 connected to the GND of the control portion 19. The contact portion 33 protrudes to the extent that it touches or does not touch the roll paper 2. The periphery of the contact portion 33 is surrounded by a rib 35 formed on the casing of the lid portion 6. Therefore, the contact portion 33 can be prevented from being caught by the roll paper 2 and deformed. The static electricity from the roll paper 2 flows to the second static electricity removing member 29 and the second static electricity removing member 29 acts as a lightning rod against the static electricity from the roll paper 2, so that the control unit 19 malfunctions due to static electricity. Can be prevented.
[0034]
An example of the operation of the roll paper supply device 1 will be described.
[0035]
The roll paper 2 is set on the holder body 3 and the lid 6 is placed on the roll paper 2.
[0036]
For example, the user turns on the first switch 21. As a result, as shown in FIG. 7, the first timer circuit 23 is actuated to drive the motor 13 for a predetermined time (long mode in the figure). When the user turns on the second switch 22, the second timer circuit 24 is activated and the motor 13 is driven for a predetermined time shorter than the first timer circuit 23 (short mode in the figure). In the long mode and the short mode, the first timer circuit 23 and the second timer circuit 24 are turned on when one of the switches 21 and 22 is turned on. Just drive.
[0037]
Further, when the user turns on both switches 21 and 22, the continuous mode is set, and the motor 13 is driven only while the switch is being pressed. At this time, the user tries to press both switches 21 and 22, but it is difficult to press them at exactly the same timing. That is, first, one of the switches is pressed first, and the other switch is pressed with a slight time difference. Therefore, the control circuit starts to operate in a mode corresponding to the previously pressed switch. On the other hand, when both switches 21 and 22 are turned on, the AND gate 25 sends a signal to the first timer circuit 23 and the second timer circuit 24 to clear the operation time of the operation being executed. Being issued, the timer function stops. In this embodiment, the immediately preceding mode is reset to shift to the continuous mode. Therefore, it is possible to prevent a malfunction such as a previous mode remaining. In the continuous mode, the first timer circuit 23 and the second timer circuit 24 do not operate, and the motor 13 is stopped when one of the switches 21 and 22 is turned off.
[0038]
In the present embodiment, the first switch 21 and the second switch 22 are set to the long mode, the short mode, and the continuous mode, respectively. However, the present invention is not limited to this. For example, the second switch 22 The second timer circuit 24 may be set to a continuous mode, and the mode may be a mode other than long, short, or continuous.
[0039]
Here, when the switches 21 and 22 are turned on, the protective sheet 36 is brought into contact with the first static electricity removing member 28 as shown in FIG. Therefore, since static electricity from the user flows through the first static electricity removing member 28 having low resistance, it is possible to prevent the control unit 19 from malfunctioning due to static electricity.
[0040]
The rotation of the motor 13 is transmitted to the feed roller 7 via the one-way clutch 17 and the speed reduction mechanism 14. Since the weight of the lid 6 is given to the feed roller 7, the roll paper 2 is rotated by the pressure without slipping and conveyed.
[0041]
When the roll paper 2 rotates, friction is generated between the casing of the holder body 3 or the lid 6 and the roll paper 2, and static electricity is charged. This static electricity flows to the contact portion 33 of the second static electricity removing member 29. Therefore, it is possible to prevent the control unit 19 from malfunctioning due to static electricity.
[0042]
When the first timer circuit 23 and the second timer circuit 24 are finished in the long mode or the short mode, or when the switches 21 and 22 are turned off in the continuous mode, the motor 13 is stopped and the supply of the roll paper 2 is stopped. The user holds the fed roll paper 2 and cuts it with the cutter 18. At this time, since the cover 6 has a sufficient weight, the roll paper 2 can be cut without pressing the cover 6 by hand.
[0043]
On the other hand, when the power supply 12 is cut off, in the event of a failure, or when it is desired to pull out the roll paper 2 of a predetermined length for a short time, the motor 13 is stopped. The roll paper 2 may be pulled out manually. When the roll paper 2 is manually pulled downward while the motor 13 is stopped, the feed roller 7 rotates and the speed reduction mechanism 14 is activated. Since the one-way clutch 17 is idle and the motor 13 is disconnected from the gear train, the roll paper 2 can be pulled out with a light force without being affected by the detent torque of the motor 13. Therefore, the operability at the time of manual operation can be improved.
[0044]
According to the present embodiment, since the roll paper 2 is continuously fed out by turning on the two switches 21 and 22, the feeding length can be arbitrarily finely adjusted. Therefore, operability can be improved. Further, since only two switches 21 and 22 are used, the cost can be reduced and the size of each switch can be increased to improve operability.
[0045]
Further, since the holder body 3 is the same as that of the current manual type paper winding machine, the installation method of the roll paper 2 is not different from the conventional one, and the operability can be maintained. In addition, the design can be made with less sense of incongruity than the conventional manual winder. In addition, compared to a manual paper-winding machine, only the lid part is enlarged, so a simple and cohesive design can be achieved. For this reason, when using it, for example in a toilet, a sense of incongruity can be made small for a narrow space.
[0046]
The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, in the present embodiment, the static electricity removing members 28 and 29 are wire springs, but are not limited thereto, and may be a metal piece or a static eliminating brush.
[0047]
In the present embodiment, the first static electricity removing member 28 is disposed on each side of each switch 21, 22. However, the present invention is not limited to this, and both switches 21, 22 are disposed close to each other. Alternatively, only one first static electricity removing member 28 may be provided. Alternatively, the first static electricity removing member 28 may be made of metal foil or metal vapor deposition provided on the surface of the protective sheet 36.
[0048]
Further, in the present embodiment, each of the static electricity removing members 28 and 29 is directly dropped to GND, but the present invention is not limited to this, and the static electricity removing members 28 and 29 may be connected via a capacitor, a coil, a resistor, or the like. In the present embodiment, each of the static electricity removing members 28 and 29 is directly attached to the substrate of the control unit 19. However, the present invention is not limited to this and may be connected via a lead wire or a flexible printed board.
[0049]
In the present embodiment, the one-way clutch 17 is provided on the most side of the motor 13 in the gear train from the motor 13 to the feed roller 7. However, the present invention is not limited to this. good. For example, when provided on the feed roller 7 side, the force applied to the one-way clutch 17 is increased when the motor 13 is driven, but the number of gears to be rotated is reduced during manual operation, so that the roll paper 2 can be pulled out with a small force. Alternatively, the one-way clutch 17 may be omitted.
[0050]
Furthermore, in this embodiment, a gear train is used as the speed reduction mechanism 14, but the present invention is not limited to this, and other speed reduction mechanisms such as a pulley and a belt may be used.
[0051]
On the other hand, in the present embodiment, the roll paper is continuously sent out by turning on the two switches 21 and 22. However, the present invention is not limited to this, and the predetermined length is different from that when the first switch 21 or the second switch 22 is turned on. May be sent out.
[0052]
In addition, the form of the switches 21 and 22 is not limited to a mechanical switch such as a push switch. Although it is expensive, it is a non-contact switch using infrared rays that is effective in terms of convenience and hygiene. A light shielding sensor or the like may be used.
[0053]
In this embodiment, two switches 21 and 22 are used. However, the present invention is not limited to this, and three or more switches may be used. In this case, another feed amount is set by turning on any two or more switches.
[0054]
In the present embodiment, the load amount changes due to the use of the roll paper 2 or the voltage decreases due to the use of a battery as the power source 12. In order to keep the rotation of 13 at a constant speed, only the on / off switch circuit or the switch circuit and constant voltage circuit, the switch circuit and constant current circuit, the switch circuit and electronic A combination of a governor circuit or the like may be used, and further, a switch and other control means may be combined. Further, the control circuit 26 of the drive unit 8 may be a switch circuit only, and a mechanical governor may be used on the drive unit 8 side.
[0055]
Furthermore, in the present embodiment, the power source 12 is accommodated in the lid portion 6, but the present invention is not limited to this, and an external power source may be used. For example, an external battery box or an AC power source can be used. In particular, the use of an AC power source can eliminate the risk of running out of batteries. Further, the control unit 19 is not limited to being housed in the lid unit 6 and may be provided outside. For example, the control unit 19 may be provided on the side of the toilet seat so that the switch operation is performed on the side of the toilet seat.
[0056]
Furthermore, in this embodiment, an appropriate pressure is applied to the roll paper 2 only by its own weight of the lid portion 6, but the pad pressure is increased to cope with many commercially available roller papers 2, that is, those with different winding tightness. When the amount is insufficient, a weight may be provided, or a spring force may be applied. In this embodiment, the rubber cutter 18 is provided. However, the present invention is not limited to this, and it may be made of other materials such as metal or may be omitted.
[0057]
