Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show the overall schematic structure of an automatic roll paper feeding device according to an embodiment of the present invention. In this embodiment, a pair of left and right brackets 21 are attached to both upper sides of the base plate 20, and a support frame 15a that supports the support frame 15b is integrally provided below the bracket 21. At the lowermost part of the base plate 20, there is provided a paper tray 17 for receiving the fed paper 16 directly below.

Roll paper 1 such as toilet paper is detachably and rotatably supported between a pair of brackets 21 via a core rod 2 passed through a center hole of the roll paper 1. .

In the support frames 15a and 15b, a continuous paper 16 drawn from the roll paper 1 is sandwiched from the front and back, and a pair of guide plates 3 for guiding the paper 16 and a sheet paper 16 are fed out. PT

Three pairs of feed rollers 6 and 7 are provided, and one of the feed rollers 6 is connected to a motor 4 for driving the rollers 6 via a drive mechanism 5. In the support frames 15a and 15b, a pair of cutters 12 and 13 for cutting the fed paper 16 are further provided, and one of the cutters 12 is driven for cutting operation. 8 is installed via a drive mechanism 9.

The feed roller 6 or the drive mechanism 5 is provided with a detector 22 for detecting the feeding amount of the paper 16 from the rotation speed of the feed roller 6 or the like. The detector 22 includes a detector for detecting the number of times the limit switch is turned on and off, and various rotary encoders using an optical sensor or a proximity sensor. The detector 22 compares the number of revolutions corresponding to the number of revolutions set in the counter (not shown) with the number of revolutions detected by the detection signal. If the number of revolutions reaches the set number of revolutions, the motor 4 is activated. It is connected to a control device (not shown) which is a feed amount judging means for stopping.

The drive mechanism 9 of the cutter 12 is provided with a detector 23 for detecting one cycle of the back-and-forth movement of the cutter 12. Upon receiving a stop signal of the motor 4, the cut motor 8 rotates. The motor 8 rotates until one cycle of the back and forth movement is completed. When the detector 23 detects one cycle, the detection signal stops the motor 8 and the cutting of the paper 16 for one unit of use previously fed is completed.

The support frame 15b is supported by the shaft 15c with respect to the support frame 15a, and the feed roller 7 is constantly pressed against the feed roller 6 by the tension spring 14 with the support frame 15a. It is urged to be.

The method of feeding the roll paper 1 is as follows. First, the roll paper 1 is supported between a pair of brackets 21 via a core rod 2, and then, as shown in a two-dot chain line diagram in FIG. The supporting frame 15b is opened by hand around the shaft 15c against the tensile force of 14 by hand, and the paper 16 from the roll paper 1 is fed out to the lower end of the guide plate 3 by hand. After that, the support frame 15b is returned to the original position so that the paper 16 is sandwiched between the feed rollers 6 and 7, so that the paper 16 is sandwiched by the feed rollers 6 and 7 so that the paper can be fed. . The feed rollers 6, 7 are preferably provided with grooves cut in the rotation direction on the surface thereof in order to prevent the paper 16 from adhering to the rollers. The rollers may be arranged at intervals. The paper tray 17 is provided with a pair of width determining side plates 18 that determine the folding width of the paper 16 that is fed and falls under its own weight. The paper 16 fed by the width-determining side plate 18 falls by its own weight, and when it comes into contact with one of the width-determining side plates 18, it is folded at that position and folded toward the other width-determining measuring plate 18. Then, folding proceeds in the same manner.

This folding may be performed by the width determining plate 18 or by automatically arranging a guide member such as a plate or a rod while the paper 16 is falling.

In addition, a medicine spraying device 19 is installed below the support frame 15a, and the medicine is automatically sprayed on the paper 16 cut in a folded state by a cutting completion signal. You may. Further, the medicine may be sprayed on the falling paper 16 or the folding paper 16. As a medicine to be sprayed, a combination of a bactericide, a lubricant, an anti-inflammatory agent and the like as appropriate is preferable.

The automatic roll paper feeding device according to this embodiment is configured to feed paper 16 continuously discharged from roll paper 1 such as toilet paper, kitchen paper, and paper towel to a length of one use unit by feed rollers 6 and 7. By pressing the operation button 24 with one touch, a series of operations up to the spraying of the pharmaceutical agent is folded, cut, and, if necessary, electrically operated automatically by a control device (not shown). Has been established.

The operation buttons may be of a non-contact type using an optical sensor or a proximity sensor in addition to the push type. Furthermore, a device that responds by voice may be provided instead of the operation button. Further, a plurality of folded papers may be automatically supplied in one operation. In this case, if the paper is picked up after one folding and cutting operation, it is detected and the next feeding, folding and cutting operation is performed automatically, so that the next use is possible. This should be set to be repeated automatically as many times as necessary. This number can be set arbitrarily. It is also preferable that the length of the paper to be folded can be set as appropriate.

Thus, the user can obtain the paper folded in a desired state without using both hands. In particular, for the elderly and people with disabilities, the operation of feeding the roll paper can be reduced. P / JP

Further, in the automatic roll paper feeding device of this embodiment, the paper feed amount of the feed roller can be freely set by a counter (not shown), so that the paper length can be arbitrarily set, and the paper is reliably used without waste. A clean cut is obtained.
