[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cassette for a towel dispensing machine, and more specifically to a towel dispensing machine that allows towels to be attached and removed, transported, and stored extremely easily. This relates to a machine cassette.

[Conventional technology] Conventionally, towels are pulled out in a loop,
You wipe your hands with the front part of this loop-shaped towel, and after use, you pull out the unused part of the towel to a predetermined length and roll up the used part, keeping the loop at all times. The gift is known.

[Problems to be Solved by the Invention] In the conventional towel dispensing machine having the structure as described above, when replacing the towel, the tip of the unused towel is set on the winding shaft, so the work of wrapping the towel multiple times is necessary. Further, the towel must be passed through a guide shaft or the like on the apparatus side so as to maintain a predetermined path and form a predetermined loop, which is extremely troublesome.

In addition, some conventional towel dispensing machines place used towels above unused towels, but when this type of towel arrangement is adopted, germs and the like inevitably fall. There was also the problem that the towels fell onto unused towels located nearby, making them unclean.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides an unused towel wrapped around a supply roller in advance, and a take-up roller around which the tip of the unused towel is wrapped in advance. A structure was adopted in which a cassette holds the cassette and the cassette for a predetermined period of time.

[Function] By adopting the above-mentioned structure, the towel can be attached and detached with one touch via the cassette,
Eliminates the troublesome work of putting on and taking off towels.

In addition, it is possible to attach an unused towel on the top and a used towel on the bottom, so that germs and the like will not fall, making it extremely clean.

[Example] The details of the present invention will be described below based on the example shown in the drawings.

FIG. 1 and subsequent figures illustrate one embodiment of the present invention, and FIG. 1 shows a perspective view of the main parts.

The towel dispensing machine according to the present invention is comprised of a main body 1 fixed to a wall, a cassette 2, and a cover 3 shown in FIG. 2 that can be opened and closed.

The main body, indicated by reference numeral 1 in FIG. 1, is formed into a housing shape from synthetic resin, metal plate, etc., and has a structure in which the front side and the lower side are open.

This main body 1 has a top plate 4, a back plate 5, and left and right side plates 6, 6, and hinge halves 7, 7 are fixed to the left and right sides of the front edge of the top plate 4.

A notch 8 into which the top end of the cover 3 is fitted is formed at the upper end of the left and right side plates 6, 6, and below this notch 8 is an L to which an unused towel supply shaft side, which will be described later, is attached. A letter-shaped notch 9 is formed.

The front end of this notch 9 is a tapered part 9a that widens toward the end, and this tapered part 9a is continuous with a straight part 9b extending in the horizontal direction, and the innermost end of the straight part 9b is a vertical part 9c. It is becoming.

Further, substantially the same notch portions 10 are formed at the lower ends of the left and right side plates 6,6.

The entrance end of this notch 10 is also a tapered part 10a, and this tapered part is continuous with a straight part 10b extending in the horizontal direction, and a vertical part 10c is continuous with the innermost end of the straight part 10b. .

A winding shaft side of a used towel, which will be described later, is attached to this notch 10.

Note that the vertical portions 9 formed on the left and right side plates 6, 6
c and 10c are arranged perpendicularly on the same straight line.

On the other hand, the cutout portions 9 and 10 of the left and right side plates 6 and 6
A long hole 11 is formed along the vertical direction on the back side of the vertical portions 9c and 10c.

A set of upper and lower drive rollers 1 is provided in this elongated hole 11.
2 and 13 are fitted with both ends rotatably supported.

The structure of the drive rollers 12, 13 is shown in FIG.

The drive rollers 12 and 13 each have a belt-like sandpaper 14 wound spirally at a predetermined pitch around each roller having a predetermined diameter.

Each drive roller 12, 13 has small diameter shafts 15, 16 and 17, 18 protruding from both ends thereof.

The small-diameter shafts 15 and 17 are fitted into elongated holes 11 formed in the side plate 6, respectively, and are rotatable in through-holes 19a formed above and below an elongated support plate 19 located outside the side plate 6. is fitted to the support plate 1
9 is fixed from the outside with screws 20.

The role of the screw 20 is to prevent the support plate 19 and the shafts 15, 16 from being separated, and the shafts 15, 17 are rotatably supported by the support plate 19.

Further, the other shafts 16 and 18 are also rotatably fitted through the elongated holes 11 into the through holes 19a of the elongated support plate 19 located outside the other side plate 6.

Note that, as shown in FIG. 3, elongated protrusions 19b are formed on the inner surfaces of the left and right support plates 19, 19, in which through holes 19a are formed above and below.

The width of the protrusion 19b is approximately equal to the width of the elongated hole 11, and is slidably fitted into the elongated hole 11 to linearly guide the drive rollers 12 and 13 in the vertical direction.

Incidentally, gears 21 and 22 are respectively fixed to the shafts 16 and 18 on the outside of the support plate 19 by screws 23.

Also, a gear 21 is provided on the outside of the right support plate 19,
U-shaped support frame 2 with 22 sandwiched from both sides.
4 is fixed by screws 25, 25.

A gear 2 is attached to this support frame 24 by a screw 25a.
7 is rotatably supported, and this gear 27 is meshed with upper and lower gears 21 and 22.

Therefore, when either gear 21 or 22 rotates, the other gear is rotated in the same direction via gear 27. That is, drive rollers 12 and 13 are rotated in the same direction.

Note that the drive rollers 12 and 13 are not in contact with each other,
They are arranged vertically and separated by a predetermined distance.

By the way, there is a notch 10 between the left and right side plates 6, 6.
A guide bar 26 is horizontally suspended above the guide bar 26 . This guide bar 26 not only reinforces the main body 1 but also guides the towel that is pulled out as will be described later, and has the role of keeping the width of the towel loops at a predetermined interval or more.

On the other hand, the cassette 2 has a grip 28 formed in a substantially U-shape as shown in FIG. A support frame 30 is formed to hold a towel wrapped several times. When the support frames 29, 30 are arcuate as shown in FIG. 1, the angle at which the support frames 29, 30 are formed for gripping the towel is 180 degrees or more.

Further, for the purpose of holding the towel, the support frames 29 and 30 may have a prismatic shape (hexagonal, octagonal, dodecagonal, etc.) as shown in FIG. 8, or a clamp-like support as shown in FIG. A frame may also be used. Furthermore, in the elliptical support frame shown in FIG. 10, protrusions A that bite into the towel are formed on both sides of the support frame. It's also enough to hold a towel. When the towel is firmly fixed, the protrusion A may be a horizontal linear protrusion, a sawtooth shape, or a large number of needle-like protrusions.

The axial directions of the support frames 29 and 30 are parallel and perpendicular to the grip 28.

Note that the distance between the axes of the support frames 29 and 30 is approximately equal to the distance between the notches 9 and 10.

Further, the diameter of the support frame 29 is approximately equal to the diameter of the unused towel wound into a roll, and the diameter of the support frame 30 is approximately equal to the diameter of the used towel when winding is started.

An unused towel 31 is fitted into the large diameter support frame 29. The unused towel 31 is wound in advance around a supply roller 32, and a shaft 32a that is fitted into the vertical portion 9c of the notch 9 is protruded from both ends of the supply roller 32.

In addition, a winding roller 3 is attached to the small diameter support frame 30.
3 is fitted with the tip of an unused towel 31 wrapped several times.

A shaft 33a is provided protruding from both ends of the winding roller 33, and this shaft 33a is guided into the vertical portion 10c of the notch 10 formed in the side plates 6, 6.

Since the support frames 29 and 30 are each formed in an arc shape extending over 180 degrees, the unused towel 31
and a winding roller 3 around which the tip of the towel is wound several times.
3 are fitted together, the open ends are elastically deformed in the opening direction and then returned to their original positions to ensure secure clamping.

Specifically, when installing an unused towel in the cassette 2, a slack portion 31a of a predetermined length is formed between the support frames 29 and 30, and a loop of a predetermined length is formed below the take-up roller 33. 31b is formed. Furthermore, considering the hygiene of the towel, the entire towel is placed in a plastic film bag or shrink-wrapped before being delivered to the user.
The packaging is designed to be easy to transport from a logistics standpoint and to prevent damage.

On the other hand, the cover 3 is formed in the shape of a housing with the back side and the bottom open, and has a size that is large enough to cover the outside of the notch 8 and below at the upper ends of the side plates 6, 6.

A hinge half 34, which is combined with the above-mentioned hinge half 7 to form a set of hinges, is fixed to the side edge side of the upper surface of the cover 3.

As is well known, the hinge halves 7 and 34 are attached to the main body 1 so as to be openable and closable by arranging their respective cylindrical parts on the same axis and fitting pins 35.

A shaft 36 is rotatably supported at the lower ends of the left and right side plates of the cover 3. A hook 37 is fixed in the middle on the inner side of the shaft 36 inside the side plate, and the hook 37 is moved counterclockwise in FIG. 2 by a spring 38 elastically loaded between it and the lower end of the side plate. It is given a rotational habit.

Further, a lever 39 is fixed to the outer end of the shaft 36 on the outside of the side plate. Therefore, the lever 39
The hook 37, which rotates clockwise in FIG. 2, compresses the spring 38 and rotates clockwise,
In this state, when the cover 3 is closed and the lever 39 is released, the hook 37 is attached to the pin 4 protruding from the outer surface of the side plate 6.
0, and the cover 3 is locked in the closed position.

Next, a method of using the towel dispensing machine according to the present invention configured as described above will be explained.

When the unused towel 31 reaches the user, it is attached to the cassette 2 and packed as described above.

The user unpacks the package, rotates the lever 39 clockwise in FIG. 2, removes the hook 37 from the pin 40, and opens the cover 3.

With the cover 3 open, hold the grip 28 of the cassette 2 and bring it close to the open side of the main body 1 with the unused towel 31 sandwiched between the large-diameter support frame 29 facing upward.

Then, the shaft 32a of the supply roller 32 is inserted into the notch 9.
It is guided into the notch 9 through the tapered part 9a.

At the same time, the shaft 33a of the winding roller 33 is
is guided into the notch 10 via the tapered portion 10a.

This state is the state shown in FIG.

At this time, the drive rollers 12 and 13 are descending downward due to their own weight, but the take-up roller 33 hits the lower drive roller 13, and the drive rollers 12 and 13
push up.

In this state, as shown in FIG.
Lead to 0c.

In this way, the shaft 32a is inserted into the vertical portion 9c.
When the shafts 3a are guided into the vertical portions 10c, the shafts 32a and 33a do not come out of the respective vertical portions 9c and 10c even if they are pulled toward the front.

Therefore, by grasping the grip 28 of the cassette 2 and pulling the cassette 2 toward you, the support frames 29 and 30 are elastically deformed and separated from the unused towel 31 and the take-up roller 33.

In addition, even if you use cassette 2, unused towels 3
1, the slack portion 31 of the towel between the upper and lower support frames 29 and 30 is removed as shown in FIGS. 4 and 5.
a is in contact with the outside of the guide bar 26.

On the other hand, when the cassette 2 is removed, the unused towel 31 located on the upper side contacts the upper drive roller 12, and the lower drive roller 13 contacts the take-up roller 33, as shown in FIG.

Also, as shown in Fig. 6, in this state, the shaft 3
The straight line connecting 2a and 33a is the drive roller 12, 1
Although it is parallel to the straight line connecting the centers of 3, the axis 32
a and 33a are closer to the front.

On the other hand, when the cassette 2 is removed, the slack part 33a
is almost on a straight line as shown in FIG. 6, the loop 31b becomes longer from the state shown in FIG. 5 to the state shown in FIG. It becomes easy to use.

In this state, the cover 3 is closed, and the lever 39 is turned to hook the hook 37 onto the pin 40, thereby locking the cover 3.

This state is the state at the start of use.

When the user pulls the front side of the loop 31b downward from this state, a rotational moment is generated in which the distance from the shaft 32a to the position where the unused towel 31 is sent out is the length of the arm, and the unused towel 31 is transferred to the supply roller 32. and rotated clockwise.

During this rotation, a downward vertical force is naturally applied to the unused towel 31, but the supply roller 32
and the drive roller 12 are not on the same axis, so
Not all downward force is applied to the drive roller 12, but a component force in the horizontal direction is generated.

Therefore, the drive roller 12 is reliably rotated as the unused towel 31 rotates.

When the drive roller 12 is rotated, the gears 21, 2
Drive roller 13 located on the lower side via 7 and 22
is rotated in the same direction as the drive roller 12, and the take-up roller 33 in contact therewith is rotated clockwise in FIG.

Accordingly, the used looped towel is wound up by a length approximately equal to the length that was pulled out.

Thereafter, the same operation is repeated, and the used towels are sequentially wound up on the take-up roller 33, and as the diameter of the wound towel increases, the drive roller 1
2 and 13 are pushed upward, and the supply roller 32
side and the drive roller 12 are always in contact, and the drive roller 13
The towel is always in contact with the rolled up towel, and the towel is fed out and wound up.

Because the towel is wound up as much as it is unrolled,
The loop length L always remains the same.

When all the unused towels have been used in this way, the diameter of the rolled up used towels is larger, so the cassette 2 is moved to the large diameter support frame 29 in the opposite direction from when the towels were attached. The towel is brought close to the main body 1 with the cover 3 facing downward, the used towel is sandwiched between the large diameter support frame 29, and the supply roller 32 is sandwiched between the small diameter support frame 30.

At this time, the pulled-out towel forming the loop is folded inside the respective support frames 29 and 30.

After installing the cassette 2 in this way, the shaft 3
When 2a and 33a are pulled out from the notches 9 and 10,
The towel can be removed from the main body 1 very easily.

When taking out the used towel, the user does not touch the used towel with his/her hands, so it is extremely hygienic.

It should be noted that the present invention is not limited to the above embodiments, but includes within its scope various modifications, design changes, etc. without departing from the technical idea of the present invention.

[Effects] As is clear from the above description, according to the present invention, an unused towel wrapped around a supply roller and a towel wrapped several times around a take-up roller are sandwiched between each other and the towel is rotated 180 degrees. Since the cassette has a structure in which multiple arc-shaped support frames are connected by grips, unused towels can be attached and stored extremely easily and hygienically, and the cassette can also be used when removing used towels. Therefore, your hands do not come into contact with used towels, making it extremely hygienic.
