Is attached to. In order to automatically retreat the main body side paper retainer 22 to the fixed position, a coil spring 31 for propelling the guide rod 29 backward is provided between the rear end of the guide rod 29 and the rear end of the guide pipe 30. Are arranged.

When the electromagnet 20 is turned on by pushing the cutter switch 7, the cam 21 is rotated, and the upper member 22A of the main body side paper presser 22 is pushed from behind by the cam 21, and the upper member 22A and the lower member 22B are coil springs. It is advanced against the spring force of 31.

Lower member 22 of main body side paper presser 22
B is mounted so as to be vertically movable by a plurality of guide rods 32 perpendicular to the upper member 22A. A coil spring 33 is also provided on the outer circumference of the guide rod 32 for returning the lower member 22B to the upper side. Further, a cam receiving bracket 34 is provided on the back surface of the lower member 22B.
Is provided, the cam receiving bracket 34 is pushed downward by the cam 21 after the upper member 22A is pushed by the cam 21 as described above, and the lower member 22B is pushed down to separate from the upper member 22A (see FIG. 10). ).

On the lower surface of the upper member 22A, a saw-toothed cutter 35 made of a single plate is horizontally fixed. The sawtooth cutter 35 includes an upper member 22A and a lower member 22B.
And moves back and forth integrally with the upper member 22A. As shown in FIG. 8, the teeth of the saw-toothed cutter 35 form an acute angle, and the tip ends of the upper member 22A and the lower member 22B when the main body side paper retainer 22 is retracted as shown in FIGS. 6 and 7. It is designed so that it does not protrude from the front surface between them.

On the other hand, the upper member 23A of the door side paper presser 23 is fixed to the back surface of the front door 2, and the lower member 23B is
The vertical guide plate 36 and the guide roller 37 are attached to the upper member 23A so as to be vertically movable.
The lower member 23B is adapted to be pulled upward by a spring 38 to an upper limit position with respect to the upper member 23A. Even in this upper limit position, a horizontal groove portion 39 is provided on the lower surface of the upper member 23A so that the teeth of the sawtooth cutter 35 on the main body side can be received between the upper member 23A and the lower member 23B. There is.

As shown in FIG. 6, the front surface of the upper member 22A and the lower member 22B of the main body side paper retainer 22 and the upper member 23A and the lower member 2 of the door side paper retainer 23.
3B is perpendicular to the rear surface, and in a normal state in which the main body side paper retainer 22 is retracted, the front surface and the rear surface face each other with a predetermined gap, and guide the toilet paper 15 that is drawn and droops as described above. You can do it. The upper edge 40 of the upper member 22A of the main body side paper retainer 22 is inclined rearward and the upper edge 41 of the upper member 23A of the door side paper retainer 23 is inclined forward so that the guide can be performed smoothly. .

When the main body side upper member 22A is pushed by the cam 21 and moves forward together with the lower member 22B as described above, the front surface of the upper member 22A is the door side upper member 23A.
At the same time as hitting the rear surface, the front surface of the lower member 22A on the main body side hits the rear surface of the lower member 23B on the door side, and the toilet paper 15 is pinched from the front and rear by these. Even after this, the upper member 22A is pushed further forward by the cam 21, and the toilet paper 15 is cut.

That is, the upper member 22A and the lower member 22B on the main body side have a structure in which the elastic member 44 such as rubber or sponge is interposed between the middle plate 42 and the front plate 43 so that it can be expanded and contracted back and forth. There is. Therefore, as shown in FIG. 9, even when the front surfaces of the upper member 22A and the lower member 22B hit the upper member 23A and the lower member 23B of the door-side paper presser 23, the elastic members are pushed forward by the cam 21. Since 44 is compressed, the teeth of the saw-toothed cutter 35 are moved toward the front surface of the upper member 22A on the main body side and the lower member 22.
It projects from the front surface of B and enters the groove-like portion 39 of the door-side paper presser 23. With such an operation, the toilet paper 15 is cut while receiving the bite of the teeth of the saw-toothed cutter 35 while being pinched from both front and rear sides.

Further, after this, the lower member 22B on the main body side
However, when it is pushed down by the cam 21 as shown in FIG. 10, since the lower member 22B and the lower member 23B on the door side are in pressure contact with the toilet paper 15 in between, the lower member 23B on the door side is also on the main body side. It descends along with the lower member 22B. On the other hand, since the upper member 22A on the main body side and the upper member 22B on the door side fix the toilet paper 15 while sandwiching it, the toilet paper 15 cut by the serrated cutter 35 is forcibly torn. Are separated from each other.

When the electromagnet 20 is turned off and the cam 21 is returned and rotated, the lower member 22B on the main body side is returned and lifted by the coil spring 33, and the lower member 2 on the door side.
3B also returns and rises due to the spring 38. Subsequently, the upper member 22A and the lower member 22B on the main body side are retracted by the coil spring 31, the front surface of these members and the rear surface of the upper member 23A and the lower member 23B on the door side are opened, and the toilet paper is newly fed out. 15 will be allowed to pass.

The above-mentioned cutting and tearing while sandwiching the pressure is performed in a state where the rotation of the drive feed roller 16 is stopped and the feeding of the toilet paper 15 is interrupted. That is, even if the feed switch 6 is pressed, the feeding of the toilet paper 15 is prohibited. The paper feed switch 6 and the cutter switch 7 can be shared by one switch.

To fold the toilet paper 15 fed out between the main body side paper retainer 22 and the door side paper retainer 23 on the paper tray 5, the inside of the main body 1 as shown in FIGS. 3 to 7. The plate folding member 45 and the swinging mechanism that swings the folding member 45 back and forth by the motor 17 are mounted as follows.

The folding member 45 is vertically oscillated by a shaft 46 near the front wall in the main body 1. A disc crank 47 is mounted in the main body 1, and the disc crank 47 and the shaft 46 are linked by a link 48.
And a lever 49. The rotation of the motor 17 is transmitted to the disc crank 47 via the belt 50, and when the motor 17 rotates, the folding member 45 becomes
It swings back and forth repeatedly at a predetermined amplitude angle, that is, between the state of a solid line that hangs a little forward of the hanging position of the toilet paper 15 in FIG. 3 and the state of a chain line that tilts backward.

Such reciprocal swinging of the folding member 45 back and forth is performed at the same time as the toilet paper 15 is fed out by the rotation of the drive feed roller 16, so that the space between the main body side paper presser 22 and the door side paper presser 23 is changed. The toilet paper 15 which hangs down falls on the paper tray 5 while being repeatedly rocked back and forth by the folding member 45, and becomes a folded state on the paper tray 5. In this case, the folding length is determined by the amplitude angle of the folding member 45. Since the folding member 45 is a plate, the folding member 45 also stops at the same time when the feeding paper 16 is stopped to be fed out by the drive feed roller 16, and the angle at the time of the stop is not the hanging state shown by the solid line in FIG. Even in the state
At the next feeding, the toilet paper 15 hangs down while sliding on the folding member 45, so that the toilet paper 15 is entangled with the folding member 45 or the toilet paper 15 is positioned in front of the folding member 45 and the next folding cannot be performed. There is no such thing.

As shown in FIGS. 1 to 3, the paper tray 5 has a bottom surface 5a, a rear surface 5b, and left and right side surfaces 5c, but has a dust removing shape with the front surface and the upper surface opened, and the center of the bottom surface 5a is slightly chevron-shaped. It is curved. This is for facilitating the folding of the toilet paper 15 and facilitating the removal of the folded toilet paper 15 from the front. In addition, the paper tray 5 has a height of the paper tray 5 which is formed by slidably fitting the pipe-shaped portion of the rear wall thereof to the left and right guide rods 4 vertically provided on the main body 1 and restricting the sliding by the set screw 51. It is adjustable. A stopper 4 a that prevents the paper tray 5 from falling is provided at the lower end of the guide rod 4.

As shown in FIGS. 7 and 11, an aroma chamber 52 is airtightly formed in one corner of the main body 1 from the other parts of the main body 1, and the inside of the aroma chamber 52 has ventilation holes. 53a
A partition wall 53 having a partition wall 52A divides the lower fragrance agent chamber 52A from the upper fan chamber 52B. The fan chamber 52B can be exhausted from the aroma blowout port 8 described above, and the aroma agent containing chamber 52A can be discharged from the aroma agent 54 (even in a container,
It can be opened / closed by the above-mentioned fragrance exchange lid 9 so that it can be exchanged and accommodated (whichever is not contained in the container). Fan 5 in the fan chamber 52B
5 is rotatably mounted. Rotation from the shaft of the drive feed roller 16 is transmitted to the fan 55 via a belt 56.

Therefore, when the drive feed roller 16 rotates and the toilet paper 15 is fed out, the fan 55 also rotates at the same time, so that the fragrance accumulated in the fragrance storage chamber 52A is once sucked into the fan chamber 52B. Is blown out from the aroma blowing port 8. The blowing is performed only while the toilet paper 15 is being fed by the drive feed roller 16.

[0039]

As described above, according to the toilet paper auto feeder of the present invention, the main body side paper retainer is advanced together with the serrated cutter, and the main body side paper retainer and the door side paper retainer sandwich the toilet paper. Since the sawtooth cutter is further advanced while being pressed to cut it while biting it into the toilet paper, the toilet paper can be surely cut.

According to a second aspect of the present invention, if the lower members of the toilet paper are pressed by the cutter drive mechanism while the toilet paper is pressed by the paper pressers on the main body side and the door side, even if the cutting by the serrated cutter is incomplete. , Toilet paper can be separated up and down to force tear.

According to a third aspect of the present invention, the structure of the cutter driving mechanism can be simplified by adopting a structure in which the cam is rotated by turning the electromagnet on and off to move the saw-toothed cutter and the main body side paper holder forward and backward.

When the toilet paper is swung back and forth with a predetermined amplitude by the folding member that swings in conjunction with the driving feed roller as in claim 4, the toilet paper has a fixed folding length on the paper tray. Can be automatically folded.

When the folding member is formed in a plate shape as in claim 5, the toilet paper hangs down so that the surface thereof slides, so that the folding member stops anywhere within the swing range at the next feeding after cutting the paper. There is no problem even if it does, and it is not always necessary to make the stop position of the folding member constant for each cycle of feeding and cutting the paper.

When the fan is rotated at the same time as the rotation of the drive feed roller to blow the aroma from the aroma chamber of the main body, the toilet paper is delivered without preparing a dedicated aroma generator or the like. Aroma can be efficiently generated only in the inside.
