Then, the inspection door 9 is opened, and the operation of the earth leakage breaker of the mechanical device inside the outer box 7 becomes possible. The upper part of the operation door 8 is locked to the outer box 7 by a locking member 8b so as to be detachable.
[0012]
An upper cover 10 is mounted on the upper surface of the outer box 7 so as to be swingable about a horizontal axis (left and right) and is opened upward. Then, by opening the upper cover 10, the roll paper 1 to be used can be mounted inside the outer box 7, and the spare roll paper 1 can be stored inside the outer box 7. The rear surface of the outer box 7 is attached to a wall of a toilet booth (not shown).
[0013]
On the left side of the outer box 7, a stock case 60 capable of storing about 5 to 10 sheets of molding paper M is attached. More specifically, the stock case 60 has a plurality of (ten in the present embodiment) shelf plates 60a arranged in the shape of a fan of a side view, and holds the paper M to be formed next to the shelf plates 60a. It is configured such that it can be stored in the storage section 66 formed by the shelf boards 60a, 60a.

Note that the stock case 60 may be configured such that a plurality of shelf boards 60a... In short, the shelves 60a are arranged so that the distance between the adjacent shelves 60a is widened or parallel from the base end to the front end in a side view, and the storage portion 66 is expanded or parallel in the opening direction of the front end. It has become.
[0014]
Both ends of the roller shaft 2 are detachably connected to the upper portions of left and right fixing plates 13 and 13 inside the outer box 7, and the roll paper 1, which is inserted through the inside of the roller shaft 2, is horizontally moved horizontally. It becomes rotatable around the axis (with the roller shaft 2).
[0015]
The roll paper 1 is, for example, toilet paper. The upper cover 10 of the outer box 7 is raised to take out the roller shaft 2, the roller shaft 2 is passed through the inside of the roll paper 1, and the roller shaft 2 is again fixed to the left and right fixing plates 13, 13. , The roll paper 1 can be mounted inside the outer box 7. This mounting method is the same as the conventional method, and the same manual operation as the conventional method can be performed at the time of machine failure or power failure. That is, in the case of manual use, the upper cover 10 is raised, the paper 1a is pulled out to the front side of the operation door 8, the upper cover 10 is closed, and the space between the upper cover 10 and the upper edge of the operation door 8 is closed. The paper 1a is sandwiched between them, and the upper cover 10 is pressed and cut, so that the same use (cutting) as in the related art can be performed.
[0016]
The delivery roller 3 is disposed below the roller shaft 2, is attached to left and right fixing plates 13, 13 inside the outer case 7 so as to be rotatable around the left and right horizontal axes, and is disposed behind the roller 3. The roller gear 3a of the roller 3 meshes with the motor gear 22 of the delivery motor 21 (with a reduction gear) provided, and the rotation of the motor 21 causes the roller 3 to rotate.
[0017]
In addition, a feeding auxiliary roller 12 is provided in front of the roller 3 so as to be opposed to the roller 3 so as to be able to approach and separate from the roller 3. 1a is configured to be squeezed with an appropriate contact pressure and drawn downward.
[0018]
More specifically, the shaft portion of the auxiliary roller 12 is movably held in a long hole 6a (in the front-rear direction) of the mounting plate 6 mounted on the rear surface (inner surface) of the operation door 8, and is compressed (compressed). The elastic member 62 (such as a spring) constantly urges the roller 3 toward the roller 3, and the auxiliary roller 12 contacts the roller 3 with an appropriate pressure when the operation door 8 is closed. The force that pushes the operation door 8 forward from the inside is only the pressing force of the auxiliary roller 12 against the roller 3 (the elastic force of the elastic member 62), and no other mechanical force acts. The operation door 8 can be maintained in a sufficiently closed state. In FIG. 4, the operation door 8 and the auxiliary roller 12 are omitted.
[0019]
The contact (pressing) position of the roller 3 and the auxiliary roller 12 with the paper 1a is set at the center of the paper width and about two thirds of the paper width (70 mm to 90 mm). Has good stability (that is, it hangs down left and right equally).
[0020]
If the outer peripheral length of the roller 3 is set to be the same as the folding width H of the molding paper M (see FIG. 14), it is easy to control, and therefore, the diameter D of the roller 3₁  Is preferably 25 mm to 35 mm. Further, by setting the gear ratio between the motor gear 22 and the roller gear 3a to 1: 1, the paper 1a having the same length as the folding width H of the molding paper M is sent out by one rotation of the motor gear 22.
[0021]
In the vicinity of the periphery of the motor gear 22, a counter tab 31 is projected, and the counter tab 31 can be brought into contact with a counter switch 32 disposed behind the motor gear 22 (the counter switch 32 is turned on every one rotation of the motor gear 22). After the motor gear 22 rotates a predetermined number of times, the feed motor 21 is stopped, so that the amount of paper 1a drawn out can be made accurate. The counter switch 32 is provided with a counter control, and is connected to a count designation unit 33 provided on the inspection door 9 shown in FIG. 1. The count designation unit 33 determines the number of rotations of the feed roller 3. . The count specifying unit 33 determines the amount of the paper 1a (the number of folded sheets) that is to be wound in a folding manner by the winding rotating body 4.
[0022]
Further, since the outer peripheral surface of the roller 3 has a small contact surface with the paper 1a, the outer peripheral surface of the roller 3 is formed so as to be able to reliably pull out the paper 1a. It is provided or formed in a gear shape. The outer peripheral surface of the auxiliary roller 12 may be roughened instead of or together with the roller 3.
[0023]
A circumferential groove 14 is formed at the center of the outer peripheral surface of the roller 3, and insertion pieces 15 a of a mountain-shaped (plate-like) delivery guide 15 disposed below the roller 3 are respectively inserted. The paper 1a vertically inserted from below into the left and right sides of the groove 3 and the roller 3 and pulled out by the rollers 3 and 12 is obstructed by the fixed cutting blade 5 disposed below the roller 3. , And can be reliably guided downward. That is, although the drawn-out paper 1a is usually curled inward (rear side) due to curl, the paper 1a is prevented from entering the inside of the paper 1a by the feeding guide 15 disposed inside the paper 1a. Can be blocked.
[0024]
The delivery guide 15 is attached to the left and right fixing plates 13 and 13 so as to be swingable, for example, by a left and right horizontal shaft portion 15b provided at a substantially central position in the vertical direction. Note that another delivery guide 15 may be provided outside (front side) of the paper 1a. Further, the feeding guide 15 is preferably made of a metal or a material that generates less static electricity in order to prevent the paper 1a from adhering due to static electricity.
[0025]
The fixed cutting blade 5 is formed in a band shape slightly larger than the width of the paper 1a, and is disposed at a position below the feed guide 15 so that the blade in the longitudinal direction faces the paper 1a side (front side). Are fixed to the left and right fixing plates 13, 13. The fixed cutting blade 5 has a configuration in which, for example, as shown in FIG. 6A, a large number of teeth 5a... Alternatively, as shown in FIG. 6B, a configuration may be adopted in which two large and small teeth 5a, 5a are provided alternately on a flat edge 5b. Even if it is thick, it can be cut. Further, it is preferable that the bottom of the tooth between the adjacent teeth 5a, 5a is formed in a circular concave shape, so that the paper fibers are less entangled when the paper 1a is cut, and the generation of dust is also reduced.
[0026]
The take-up rotary member 4 is disposed below the fixed cutting blade 5, and includes a rotary plate 40 and two (round) folds symmetrically provided on the rotary plate 40 with respect to the axis L thereof. Tatami rods 41, 41, and is configured to wind up the paper 1a disposed between the two fold rods 41, 41 in a flat fold shape.
[0027]
For example, as shown in FIG. 7, the take-up rotary body 4 has a base portion 48 attached to a base end of a folding rod 41, a long hole 48 a (in a radial direction) is formed in the base portion 48, and the base portion 48 is formed. However, it is attached to the rotating plate 40 by a fastener 61 (such as a bolt) inserted through the elongated hole 48a, so that the two folding rods 41, 41 can approach and separate from each other. The surface of the rotating plate 40 is provided with a diametrical groove 40a (about 1 mm) into which the substrate portion 48 is fitted, and the substrate portion 48 is fixed to the rotating plate 40 in a stable state. Further, the fastening tool 61 can be screwed into a tap hole formed through the rotating plate 40.
[0028]
The interval between the two folding rods 41, 41 determines the folding width H (see FIG. 14) of the paper M to be wound by the two folding rods 41, 41. It is set so that the paper 1a sent out in two rotations is wound in one rotation.
[0029]
The rotary plate 40 is mounted on the left side plate 11 (fixed plate 13) of the outer box 7 so as to be rotatable around the left and right horizontal axis L, and is disposed behind the rotary plate 40 (reduction gear). A gear formed on the outer peripheral surface of the rotating plate 40 meshes with a motor gear 24 of the folding motor 23), and the rotating plate 40 is rotated by the rotation of the folding motor 23.
[0030]
Note that the gear ratio between the motor gear 24 of the folding motor 23 and the gear of the rotary plate 40 is set to 1: 2, and one rotation of the motor gear 24 makes the number of sheets folded by the winding rotary member 4 one. When the paper 1a has a thickness or strength such as double paper, it is also desirable to operate the rotating plate 40 such that the rotating plate 40 is rotated backward by about 90 ° (stopped once) and then rotated forward again.
[0031]
Further, one stop tab 52 is protruded near the periphery of the motor gear 24, and the stop tab 52 can come into contact with a stop switch 53 disposed above the folding motor 23, and the two folding rods 41 are provided. , 41 is stopped at a position where the direction connecting the horizontal plane and the horizontal plane forms an angle of 0 ° to 15 ° with respect to the horizontal plane. This set angle is to lengthen the contact time between the paper 1a wound around the folding rod 41 and the tightening portion 47 (as described later).
[0032]
In the case where the roll paper 1 is toilet paper, the output motor 21 and the folding motor 23 need only have a 42 mm square output of 1 W. For example, when the roll paper 1 is a roll paper such as a new standard paper towel. , A 60 W square output of 4 W is sufficient.
[0033]
An oscillator 44 that oscillates a signal such as a light beam or a radio wave is provided at a lower rear position of the rotating body 4, and a take-up stop geophone 45 is provided at a lower front position of the rotating body 4. An operation start geophone 46 is disposed at the upper front position of 4, and the oscillator 44 oscillates signals to the winding stop geophone 45 and the operation start geophone 46 at the same time. Alternatively, if the oscillation amplitude of the oscillator 44 is narrow, two oscillators 45 and 46 may be provided for each.
[0034]
The take-up stop geophone 45 sends a signal to the stop switch 53 by receiving a signal from the oscillator 44, and immediately after receiving the signal, the rotary plate 40 (the folding motor 23) when the stop tab 52 presses the stop switch 53. To stop. Incidentally, it is preferable that the take-up rotating body 4 is further rotated by about 1 to 2 turns by a timer control or the like and then stopped, thereby further tightening the paper.
[0035]
The operation start vibrator 46 receives a signal from the oscillator 44 to send a signal to the feed motor 21, and rotates the feed roller 3 again to draw out the paper 1a.
[0036]
The folding rod 41 is provided so as to be able to contact the range of substantially the entire width of the paper 1 a, and is provided on the front side of the notch 18 provided on the right side of the operation door 8 and the right side plate 11. The paper 1a (paper M to be formed) wound around the folding rods 41, 41 can be grasped and taken out from the opening 20 formed by the notch 19 formed by the folding.
[0037]
The outer peripheral surface of the folding rod 41 is formed smoothly, so that the paper 1a easily slides on the outer peripheral surface of the folding rod 41.
[0038]
There is provided a winding portion 47 which is inserted into the rotation circle C of the winding rotary member 4 and contacts the paper 1a wound by the winding rotary member 4 to apply a tightening force. Here, the rotation circle C refers to a circle that is inscribed when the portion of the winding rotary member 4 that winds the paper 1a (that is, the folding rods 41, 41) rotates. More specifically, a (band-shaped) wind-up portion 47 is inserted in the rotating circle C in the latter half of the rotating body 4 in a hanging manner, and comes into contact with the paper 1a wound by the folding rods 41, 41. To provide a tightening force. As described above, the winding portion 47 fits easily into the main body, and does not hinder the feeding of the paper 1a.
[0039]
The winding portion 47 is formed by, for example, stacking a plurality of cloths (such as non-combustible cloths) that do not fray even if worn, and heat-welding them with a high-frequency sewing machine or the like in horizontal stripes (transverse shape). It is manufactured so as to form wavy irregularities on the contact surface with the paper 1a, so that the contact pressure with the paper 1a can be increased and a stronger tightening force can be applied.
[0040]
The left and right widths of the fastening portion 47 are set shorter than the length of the folding rod 41, and the fastening portion 47 is disposed within the length of the folding bar 41. Therefore, the winding portion 47 does not block the signal of the oscillator 44.
[0041]
The vertical length of the tightening portion 47 is set to be longer than the diameter of the rotating circle C, and the folding rod 41 is configured to reliably contact the tightening portion 47 for a long time.
[0042]
A weight 54 (of 3 to 10 grams) is attached to the lower end of the tightening portion 47, so that the tightening force can be further increased. Of course, the weight 54 may be omitted. Further, it is preferable to increase the winding tightening force by further rotating the take-up rotating body 4 by one to two extra turns by timer control or the like.
[0043]
The upper base end of the winding portion 47 is attached to a slide plate 55 that can move in the front-rear direction, and the front-rear position can be adjusted. More specifically, an adjustment lever 56 is attached to the slide plate 55, and the adjustment lever 56 is engaged with and disengaged from the locking irregularities of the adjustment window 57 penetrating the right side plate 11 and the right fixing plate 13 of the main body. By doing so, the slide plate 55 can be fixed at a desired front-rear position, for example, as shown by the solid line and the virtual line in FIG. Therefore, the front and rear positions of the slide plate 55 can be easily adjusted by operating the adjustment lever 56 from outside the main body.
[0044]
That is, as shown by the solid line in FIG. 5, when the fastening portion 47 is fixed at the front position, the bending angle θ of the fastening portion 47 formed when the fastening portion 47 comes into contact with the folding rod 41 on the folding rod 41 side. Becomes smaller, the contact pressure with the folding rod 41 increases, and the tightening force increases. On the other hand, as shown by the imaginary line in FIG. 5, when the fastening portion 47 is fixed at the rear position, the bending angle θ increases, the contact pressure with the folding rod 41 decreases, and The power becomes weak. In short, by adjusting the front and rear positions of the slide plate 55, the strength of the winding force can be adjusted.
[0045]
A paper receiving tray 38 for storing the paper 1a pulled out by the feed roller 3 is provided below the rotating body 4, and a metal bent in a letter shape as viewed from the side is provided at the bottom of the paper receiving tray 38. A plurality (five in the present embodiment) of the wires 51 are arranged in the left-right direction at predetermined (for example, 15 to 20 mm) intervals. The apex of the metal wire 51 is located slightly forward of the tip of the hanging paper 1a, and the accumulation of the paper 1a, which tends to be skewed toward the front of the paper receiving tray 38, can be appropriately accumulated in the rear. Therefore, when the apparatus is handled with wet hands, water droplets may fall near the opening 20 of the outer box 7, but the paper 1a is not wet by the falling water droplets due to the metal wires 51. Further, the paper receiving tray 38 is housed in the outer box 7 so as to be able to be pulled out to the outside, and it is possible to easily take out (clean) water droplets or dust such as paper accumulated at the bottom.
[0046]
Next, the operation (function) of the present invention will be described. It is to be noted that the case where the count designation unit 33 (see FIG. 1) is set to four folded sheets (the minimum designated number) is shown.
[0047]
First, the operation door 8 shown in FIG. 3 is opened. At this time, the operation door 8 is separated from the door switch 50 provided behind the operation door 8, and the door switch 50 is turned off, and all the power in the machine is turned off. At the same time, the auxiliary roller 12 attached to the operation door 8 is separated from the roller 3 as shown in FIG. Then, the paper 1a drawn from the roll paper 1 is dropped until it reaches the fixed cutting blade 5 between the roller 3 and the auxiliary roller 12 and through the front surface of the delivery guide 15, and the operation door 8 is closed. At this time, the elastic force of the elastic member 62 causes the paper 1a to be sandwiched between the roller 3 and the auxiliary roller 12 at an appropriate pressure. At the same time, the door switch 50 is turned on, and the power inside the machine is turned on. Start operation of the machine.
[0048]
Then, as shown in FIG. 8 (b), the paper 1a having a predetermined length (designated) is pulled out by being squeezed between the roller 3 and the auxiliary roller 12, and passed between the folding rods 41, 41. Is sent to the paper tray 38 (accumulated).
[0049]
Thereafter, the rotation of the roller 3 is stopped, and a predetermined amount of the paper 1a is wound around the rotating body 4 while the folding rod 41 is in contact with the winding portion 47 as shown in FIG. As shown in FIG. 9B, the folding rods 41, 41 come into contact with the front and rear surfaces of the paper 1a, respectively. At this time, the folding rod 41 is separated from the winding part 47, and the winding part 47 is in a state of hanging vertically.
[0050]
When the rotating body 4 is further rotated, as shown in FIG. 10 (a), the folding rods 41, 41 slide with the base end of the paper 1a while the paper 1a (in the paper receiving tray 38). And wind it from the tip side. At this time, the winding portion 47 is bent into a dogleg shape by the inertia of the weight 54, so that the paper 1 a can be strongly wound around the folding rod 41. Note that the paper 1a abuts below the feed guide 15, but the pressing force of the paper 1a is small, so that the lower portion of the feed guide 15 does not swing backward.
[0051]
Then, as shown in FIG. 10B, the paper 1a wound around the folding rod 41 comes into contact with the base end of the paper 1a (due to frictional resistance), and the paper 1a above the rotating body 4 is removed. It will be pulled downward. At this time, since the paper 1a to which the tensile force has been applied comes into contact with the lower portion of the feed guide 15 with an excessive pressing force, the lower portion of the feed guide 15 swings backward around the shaft portion 15b and escapes. 1 a comes into strong contact with the fixed cutting blade 5.
[0052]
Thereafter, as shown in FIG. 11A, the paper 1a strongly pressed against the fixed cutting blade 5 is cut. At this time, since the lower portion of the feed guide 15 returns to the original position around the shaft portion 15b, even if the fibers of the paper 1a located above the fixed cutting blade 5 are entangled with the fixed cutting blade 5, Is released, thereby facilitating the feeding of the paper 1a in the next step.
[0053]
Thereafter, the leading end side of the cut paper 1a is wound around the rotating body 4 as shown in FIG. 11B, and between the oscillator 44 and the take-up stop geophone 45 as shown in FIG. When the paper 1a has run out, the take-up stop geophone 45 receives the signal from the oscillator 44, detects that there is no paper 1a below the rotating body 4 (the paper tray 38), and sends a signal to the stop switch 53. As shown in FIG. 12B, the rotating body 4 stops when the stop tab 52 presses the stop switch 53 immediately after receiving the signal.
[0054]
At this time, the molding paper M is wound around the rotating body 4, but the proximal end of the paper 1 a can be aligned by the winding portion 47. That is, when the winding portion 47 is set at the front position, the base end of the paper 1a shifts forward, and when the winding portion 47 is set at the rear position, the base end of the paper 1a shifts rearward.
[0055]
Then, the user puts his hand through the opening 20 (see FIG. 1) of the outer box 7, and as shown in FIG. 13 (a), the gripping area N (folded into four sheets) of the molding paper M ( (Between the folding rods 41, 41) and pull out in the direction of the axis L of the rotating body 4. Then, as shown in FIG. 13 (b), the operation start geophone 46 receives the signal from the oscillator 44, and the rotating body 4 does not have the molding paper M (that is, the oscillator 44 and the operation start geophone 46). Is detected, the operation of the feed roller 3 is immediately restarted, and a new paper M is formed. The molded paper M extracted from the rotating body 4 can be used as it is because it is already folded flat as shown in FIG.
[0056]
Next, FIG. 15 shows another embodiment of the present invention, and the following configuration is clearly different from FIG.
[0057]
That is, in FIG. 15, an L-shaped swinging plate 58 is provided in a side view, and a shaft portion 58a is provided at a bent portion of the swinging plate 58 so that the swinging plate 58 can swing around the shaft portion 58a. Is fixed to the fixing plate 13. The winding portion 47 is attached to one end of the swing plate 58, and the adjustment lever 56 is attached to the other end of the swing plate 58. The adjusting lever 56 can be engaged with and disengaged from the locking uneven portion of the vertically long arc-shaped adjusting window 57. Then, when the adjusting lever 56 is swung downward from above, the tightening portion 47 swings forward from behind. That is, as shown by the imaginary line and the solid line in FIG. 15, the rocking force (bending angle θ) of the winding portion 47 can be adjusted by swinging the swinging plate 58 around the shaft portion 58a. it can. In this manner, the swinging plate 58 that swings can be arranged at a position behind the fixed cutting blade 5.
[0058]
