It does not require precision and can be configured relatively easily.

The feeding feeding device unit 12 is a known device such as one configured by a feeding feeding mechanism that operates so as to sandwich the toilet paper 10 between a pair of feeding rollers 12a and 12b as shown in FIG. 1 and pull it downward. Can be selectively used as appropriate. One of the pair of feed rollers 12a and 12b is a drive roller driven by a motor, and the other is a driven roller that rotates and applies rolling compaction while pressing the toilet paper 10 so as to give friction for feeding. Can be. If the toilet paper 10 can be fed so as to be sufficiently pulled out by the winding means by the folding process unit 15, it is not necessary to provide the above-mentioned feeding and feeding device unit 12 as an independent mechanical unit.

As the cutting device unit 13, for example, a known device such as one that cuts the toilet paper 10 by moving the cutter blade left and right by a motor along the cutter receiving blade portion extending to the left and right is appropriately selectively used. can do.

Next, a morphological example of the folding process unit 15 according to the present invention will be described in detail.
Reference numeral 20 denotes a take-up member, which is in contact with each of the sides of both ends of the toilet paper 10 and is arranged in a state in which one pair 20 and 20 face each other so as to wind the toilet paper 10. In the form example of the winding member 20 shown in FIG. 1, the winding member 20 is provided in a columnar shape, and the outer peripheral surface is formed into a knurled rough surface so that the toilet paper 10 can be suitably wound by friction. .. In order to increase the frictional force of the winding member 20, the outer peripheral surface thereof should be a rough surface of another form, or a material having a high friction coefficient such as a rubber material should be used as the material for forming the surface thereof. Can be done.

That is, in this embodiment, the pair of winding members 20 and 20 are winding rollers 20A and 20A, respectively, and are provided in a roller shape. In order to reliably wind the toilet paper 10, it is better that the width of the peripheral surface in contact with the toilet paper 10 (extension direction of the axis) is large and long, and it is easy to pull out the wound toilet paper 10A. In order to lower the toilet paper quickly, it is better that the width of the peripheral surface in contact with the toilet paper 10 (the width in the extension direction of the axis) is small and short. Therefore, the most appropriate fitting dimension may be appropriately and selectively set in consideration of the relationship between the two and other conditions such as the characteristics of the toilet paper 10 itself and the characteristics related to the operation mechanism of the device.

Reference numeral 30 denotes a rotating device, which rotationally drives a pair of winding members 20, 20. According to the rotating device 30, by interlocking and rotating the pair of winding members 20 and 20 in synchronization with the feeding operation of the feeding feeding device unit 12, the toilet paper 10 can be appropriately wound and wound. A circular toilet paper 10A can be formed.

The configuration of the rotating device 30 is shown in FIG. 1 as a pair of identical device configurations, but this is for convenience of description and requires a pair of drive sources (motor, etc.). Of course, the mechanism may be driven by a single motor, and a known rotational drive mechanism can be selectively used as appropriate.

Reference numeral 40 denotes a reciprocating device, in which the toilet paper 10 is wound to form a wound toilet paper 10A (see FIG. 4), and then the pair of winding members 20 and 20 are wound with a wide axial interval. The pair of winding members 20 and 20 are provided so as to move in contact with and separate from each other in the axial direction so that the circular toilet paper 10A can descend downward (see FIG. 5). According to the reciprocating device 40, the winding toilet paper 10A is separated from the pair of winding members 20 and 20 by interlocking with the operation of the feeding device unit 12 and the rotating device 30 in synchronization with each other. It works to lower properly.

The configuration of the reciprocating device 40 is shown in FIG. 1 as a pair of identical device configurations, but this is for convenience of description, and a pair of drive sources (motor, solenoid, cylinder device, etc.) ) Is not required, and it is of course possible to use a mechanism that drives the pair of winding members 20, 20 in a reciprocating linear motion state by a single drive source. The mechanism can be selectively used as appropriate.

Reference numeral 50 denotes a folding receiving portion, which is a portion that receives and holds the wound-shaped toilet paper 10A that descends downward. As shown in FIG. 1, the folding receiving portion 50 is provided with an inner bottom portion 51 that receives the wound-shaped toilet paper 10A that has descended downward, and guides the wound-shaped toilet paper 10A so as not to shift to the left or right. The left and right side wall portions 52 and 52 are provided. The left and right side wall portions 52, 52 hit the end faces of the wound toilet paper 10A so as not to shift to the left or right when each of the pair of winding members 20, 20 is pulled out from the wound toilet paper 10A. It is a part that guides the descent so that it does not shift to the left or right when the wound toilet paper 10A descends and is received by the inner bottom 51 while being in contact with the toilet paper 10A. Further, the back side of the inner bottom portion 51 is an inclined surface that inclines toward the front side, and is a guide surface that guides the wound toilet paper 10A so that it can be lowered to the front side and positioned appropriately. ..

Reference numeral 60 denotes a folding pressing device, which is a device that presses the wound toilet paper 10A so as to be flatly crushed with the folding receiving portion 50 and formed into a fold shape.
In this embodiment, the pressing plate 61 of the folding pressing device 60 descends from above and sandwiches the wound toilet paper 10A between the folding pressing device 60 and the inner bottom portion 51 of the folding receiving portion 50. Is a mechanism for forming a foldable toilet paper 10B, and is a vertical movement mechanism for moving the pressing plate 61 up and down. Although the drive device of the folding pressing device 60 is not shown, known technologies such as a motor and a cylinder device can be selectively used as the drive source, and the drive mechanism includes a gear mechanism and a link mechanism. The known techniques of the above can be selectively used as appropriate.

However, the folding pressing device 60 according to the present invention is not limited to this. For example, when the roller presses and rotates, the folding toilet paper 10A is pressed so as to be folded. It suffices if the device can be appropriately molded into a foldable toilet paper 10B by pressing the wound toilet paper 10A, such as a mechanism for molding into the toilet paper 10B of the above, and known techniques are appropriately and selectively used. be able to.

Further, the take-up roller 20A of the present embodiment is provided with a temporary holding device 22 for temporarily holding the tip of the toilet paper 10 along the outer peripheral surface of the take-up roller 20A during the take-up process. That is, as shown in FIG. 2, the tip of the toilet paper 10 may be operated so as to be held along the outer peripheral surface of the roller 20A.
The temporary holding device 22 includes a clip device that temporarily clips and holds the tip of the toilet paper 10 by an elastic force such as a spring, and a temporary holding device 22 that temporarily clips and holds the tip of the toilet paper 10 by a vacuum pressure. Known techniques such as a suction holding device for sucking and holding can be selectively used as appropriate.

By the way, in this embodiment, the number of times the toilet paper 10 is wound by the winding roller 20A is double winding as shown in FIGS. 4 to 7, and the number of times the toilet paper 10 is wound is triple. The foldable toilet paper 10B to be used has a form in which 12 papers are overlapped. Therefore, in the case of double (double) toilet paper, if the number of windings is tripled, the foldable toilet paper 10B to be used becomes a form in which 12 papers are overlapped. Further, in the case of a single toilet paper, when it is wound 6 times, it becomes a foldable toilet paper 10B equivalent to the above.

Further, reference numeral 55 denotes an auxiliary roller, which operates so as to sandwich the toilet paper 10 with the outer peripheral surface of the take-up roller 20A and apply rolling compaction so that the toilet paper 10 can be wound smoothly. It works.

Next, another embodiment of the folding process unit 15 according to the present invention will be described.
In this embodiment, as shown in FIG. 8, each of the pair of winding members 20, 20 is a winding fork-shaped member formed in a fork shape having a portion extending inward in parallel along the axis. It is characterized by being 20B. That is, the take-up fork-shaped member 20B has a shape similar to a fork having an open tip side and a closed root portion, and has an axial extension direction on the root portion side (a pair of take-up forks facing each other). When the members 20B are moved in a direction in which they are separated from each other), they can be appropriately pulled out of the wound toilet paper 10A.

The pair of winding fork-shaped members 20B and 20B, which are the pair of winding members formed in this way, are also used to form the foldable toilet paper 10B in the same manner as in the embodiment described with reference to FIGS. Can work properly. In the case of the form example using the pair of winding fork-shaped members 20B and 20B, the shape of the wound-shaped toilet paper formed by winding is a flat shape, so that the flat wound-shaped toilet paper is formed. It is possible to obtain the foldable toilet paper 10B by simply lowering the toilet paper, and unlike the case of using the pair of winding rollers 20A and 20A, the pressing step by the fold pressing device 60 can be omitted. Is.

However, even in the case of the embodiment in which the pair of winding fork-shaped members 20B and 20B are used, a more reliably molded foldable toilet paper 10B can be obtained by performing the pressing step by the folding pressing device 60. Of course. Further, in order to prevent the left and right displacement of the foldable toilet paper 10B when the pair of winding fork-shaped members 20B and 20B come out, the foldable toilet paper 10B is pressed by pressing from above the fold pressing device 60. It may be possible to prevent left-right deviation and assist smooth descent. In this case, the form of the pressing plate 61 of the folding pressing device 60 may be appropriately modified so as to prevent the left and right displacement of the folding toilet paper 10B. Further, in order to prevent the left and right side walls of the foldable toilet paper 10B from being displaced when the pair of winding fork-shaped members 20B and 20B come out, the left and right side wall portions 52 and 52 of the winding fork-shaped member 20B The fork portion may be modified to include a slit portion that allows the fork portion to move in and out along the extension direction of the axis.

Although various examples of the present invention have been described above, the present invention is not limited to the examples of the present invention, and it goes without saying that many modifications can be made without departing from the spirit of the invention. That is.
