Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a towel dispensing machine, and more particularly to a towel dispensing machine in which towels are attached and removed, transported, and stored using cassettes. .

[Prior art] Conventionally, a towel is pulled out in a loop shape, the front part of the loop-shaped towel is used to wipe hands, and after use, the unused part of the towel is pulled out to a predetermined length and the towel is unused. A towel dispensing machine is known that has a structure that winds up the finished part and always maintains a loop.

In such a towel dispensing machine, a supply roller around which unused towels are wound and a take-up roller around which used towels are wound are arranged above and below, and a roller that can freely rotate and move up and down between them is arranged vertically. A pair of upper and lower drive rollers are arranged in an interlocking relationship, with the upper drive roller being in contact with the outer circumferential surface of the unused towel, and the lower drive roller being disposed in contact with the outer circumferential surface of the used towel. There is.

Therefore, when an unused towel is pulled out, the take-up roller is rotated via the pair of upper and lower drive rollers in an interlocking relationship, and the used towel can be wound up.

[Problems to be Solved by the Invention] However, the straight line connecting the axes of the supply roller and the take-up roller and the straight line connecting the axes of the pair of upper and lower drive rollers are on the same axis.

Therefore, when the unused towel that has been pulled out in a loop is pulled downward, the downward load applied to the unused towel acts perpendicularly toward the axis of the drive roller located on the upper side.

When this phenomenon occurs, the load applied vertically downward is greater than the rotating force of the unused towel, so the rolled unused towel cannot be rotated, the drive roller cannot rotate, and the unused towel cannot be rotated. You will not be able to extend your legs.

[Means for Solving the Problems] In the present invention, in order to solve the above-mentioned problems, an unused towel is wound into a roll and is rotatably supported between the left and right side plates of the dispensing machine main body. A supply roller, a supply roller that is rotatably supported between left and right side plates vertically below the supply roller, around which an unused towel is wrapped, and an upper and lower set that is rotatably and vertically supported between the left and right side plates. The drive roller located on the upper side is in contact with the outer peripheral surface of the unused towel, and the drive roller located on the lower side is in contact with the outer peripheral surface of the used towel. A structure is adopted in which the straight line connecting the axes of the supply roller and take-up roller is located closer to the back plate side of the main body than the straight line connecting the axes of the supply roller and take-up roller.

[Function] When the above structure is adopted, the axes of the supply roller and take-up roller are offset, so the downward load when pulling out an unused towel is applied perpendicularly to the axis of the drive roller. The rotational moment applied to the rolled unused towel effectively functions to rotate the unused towel and also rotate the drive roller.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

Figure 1 and the following diagrams explain one embodiment of the present invention.
The figure shows a perspective view of the main parts.

The towel dispensing machine according to the present invention has a main body 1 fixed to a wall surface.

A cutout 8 into which the upper end of the cover 3 is fitted is formed at the upper end of the left and right side plates 6, 6. Below the cutout 8, an unused towel supply shaft 1, 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 9 that widens at the end.
This tapered part 9a is continuous with a straight part 9blCi extending in the horizontal direction, and the innermost end of the straight part 9b is a vertical part 9C.

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 also has 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 formed at the innermost end of the straight part 10b.
are continuous.

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

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

On the other hand, a long hole 11 is formed along the vertical direction on the back side of the vertical portions 9C, 10c of the cutout portions 9.10 of the left and right side plates 6, 6.

A pair of upper and lower drive rows 512.degree. 13 are fitted into the elongated hole 11 with both ends rotatably supported on the shaft.

The structure of the drive row 512.13 is shown in FIG.

The driving rows 512, 13 are rollers having a predetermined diameter, and the sand vapor 1 is spirally formed into a strip at a predetermined pitch.
4 is wrapped.

Each of the drive rollers 12, 13 has small diameter shafts 15.16 and 17.18 projecting 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 at the top and bottom of an elongated support plate 19 located outside the side plate 6. and is fixed from the outside of the support plate 19 with screws 20.

The role of the screw 20 is to prevent the support plate 19 and the shaft 15.17 from being separated, and the shaft 15.17 is rotatably supported by the support plate 19.

Further, the other shaft 16 , 18 is also rotatably fitted through the elongated hole 11 into the through hole 19 a 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 protruding portion 19b is approximately equal to the width of the elongated hole 11, and is slidably fitted into the elongated hole 11.
13 in a straight line 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.

In addition, on the outside of the right support plate 19, a support frame 24 in the shape of an opening is provided with screws 25 and 24, so as to sandwich the gears 21 and 22 from both sides.
25.

A gear 27 is rotated by a spring 25a on this support frame 24.
This gear 27 is rotatably supported, and this gear 27 is connected to the upper and lower gears 2.
1.22.

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

Note that the driving rollers 12 and 13 are not in contact with each other, but are placed vertically apart from each other by a predetermined distance.

Incidentally, a guide bar 26 is horizontally suspended above the notch 10 between the left and right side plates 6.6.

This guide bar 26 not only reinforces the main body 1, but also
As will be described later, it guides the towel that is pulled out and has the role of keeping the width of the towel loops at a certain distance or more.

On the other hand, as shown in FIG. 1, the cassette 2 has a grip 28 formed in a substantially mouth shape, and an arc-shaped support frame 29 with a large diameter is integrally formed at the upper end of this grip 28. . The forming angle of this support frame 29 is over 180 degrees.

At the lower end of the grip 28, a support frame 30 forming a small diameter arc is formed at a predetermined distance over an angular range of 180 degrees or more.

The axial directions of the support frames 29 and 30 are parallel, and the grip 2
It is arranged perpendicular to 8.

Note that the spacing between the axes of the support frames 29 and 30 is equal to the notch 9.
, 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 pre-wound around a supply roller 32, and a shaft 32a that is fitted into the vertical portion 9C of the notch 9 projects from both ends of the supply roller 32.

In addition, an unused towel 31 whose tip end is wound several times around a winding roller 33 is fitted into the small-diameter support frame 30 .

A shaft 33a is protruded from both ends of the winding roller 33, and this shaft 33a is inserted into the notch 1 formed in the side plates 6, 6.
0 into the vertical section 10c.

Since the support frames 29 and 30 are each formed in an arc shape extending over 180 degrees, when an unused towel 31 and a winding roller 33 with the tip of the towel wound several times are fitted, the open ends thereof open. After being elastically deformed in this direction, it returns to its original shape and is securely clamped.

Specifically, when attaching an unused towel to the cassette 2, a slack portion 3 of a predetermined length is inserted between the support frames 29 and 30.
1a and is attached with a loop 31b of a predetermined length formed on the underside of the winding roller 33. Furthermore, in consideration of the hygiene of the towel, the entire towel is placed in a plastic film bag or shrink-wrapped to ensure that it reaches the user, is easy to transport from a logistics standpoint, and is designed to prevent destruction. be done.

On the other hand, the cover 3 is formed in the shape of a casing with the back side and 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.

Behind the top surface of the cover 3 and on the side edge side, there is the hinge half 7 described above.
A hinge half-rest 34, which is combined with the hinge to form a set of hinges, is fixed.

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 the pin 35 thereto.

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 side plate at the inner end of the shaft 36.
7 is provided with the ability to rotate counterclockwise in FIG. 2 by a spring 38 elastically loaded between the lower end of the side plate.

A lever 3 is also provided at the outer end of the shaft 36 on the outer side of the side plate.
9 is fixed. Therefore, when the lever 39 is rotated clockwise in FIG. The cover 3 is locked in a closed state by being engaged with a bottle 40 protruding from the outer surface.

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 bottle 40, and removes the cover 3.
open.

With the cover 3 open, grasp the grip 28 of the cassette 2 and remove the unused towel 31 sandwiched between the large-diameter support frame 29.
With the side facing up, approach the open side of the main body 1 and pull it.

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

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

This state is the state shown in FIG.

At this time, the drive rows 512 and 13 are descending downward due to their own weight, but the winding roller 33
, and pushes up the drive rollers 12 and 13.

In this state, as shown in FIG.
2 into the vertical portion 9C and the shaft 33a into the vertical portion 10c.

In this way, when the shaft 32a is guided into the vertical portion 9c and the shaft 33a is guided into the vertical portion 10c, even if the shaft 32a is pulled toward the front, the shaft 33a is guided into the vertical portion 9c.
2a and 33a do not come out from the respective vertical portions 9c and 10c.

Then, grasp the grip 28 of the cassette 2, and
If you pull it toward you, the support frame 29° 30 will hold the unused towel 3.
1 and the take-up roller 33 by elastic deformation.

Note that even if the cassette 2 is used, when the unused towel 31 is attached, the upper and lower support frames 29 are removed as shown in FIGS. 4 and 5.
．． The slack portion 31a of the towel between 30 and 30 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 number 60.

Further, as shown in FIG. 6, in this state, the shafts 32a and 3
Although the straight line connecting the drive rollers 12 and 3a is parallel to the straight line connecting the centers of the drive rollers 12 and 13, the shafts 32a and 33a are shifted toward the front side.

On the other hand, when the cassette 2 is removed, the slack portion 33a becomes almost straight as shown in FIG. 6, the loop 31b becomes longer from the state shown in FIG. 5 to the state shown in FIG. 6, and the interval J becomes wider. , the space between the loops can be inserted to make it easier to use.

In this state, cover 3 is closed, lever 39 is turned to hook hook 31 onto bottle 40, and cover 3 is locked.

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.
The unused towel 31 is rotated clockwise together with the supply row 532.

During this rotation, a downward vertical force is naturally applied to the unused towel 31, but the supply row 532 and the drive roller 1
2 is not on the same axis as the drive row 512, the entire downward force is not applied to the drive row 512, and a component force in the horizontal direction is generated.

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

When the drive roller 12 is rotated, the drive roller 13 located at the lower side rotates through the gears 21, 27, 22.
A take-up roller 33 rotated in the same direction as and in contact with the winding roller 33
is rotated clockwise in FIG.

Therefore, 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 winding roller 533. As the diameter of the wound towel increases, the drive rollers 12 and 13 are pushed upward, and the rollers 12 and 13 are pushed upward to the supply roller 32 side. The drive roller 12 is always in contact with the towel, and the drive roller 13 and the rolled up towel are always in contact with each other, and the towel is fed out and wound up.

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

When all the unused towels are used up 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 2 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 towels that have been pulled out and forming a loop are folded inside the respective support frames 29 and 30.

After installing the cassette 2 in this way, the shafts 32a, 3
When the towel 3a is pulled out from the notches 9 and 10, the towel is removed from the main body 1.
It comes off 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.

Note that the present invention is not limited to the above embodiments,
The scope includes various modifications, design changes, etc. without departing from the technical idea of the present invention.

[Effect] As is clear from the above explanation, according to the present invention, since the shaft center of the rolled unused towel and the shaft center of the drive roller are shifted from each other, there is no difference in the towel delivery position. I3
(The downward load that pulls is not applied perpendicularly to the axis of the drive roller, but effectively functions as a rotational moment for the rolled unused towel, ensuring that the unused towel is pulled out and the used towel can be reliably wound.
