Description

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

[Problems to be solved by the invention] In the conventional towel dispensing machine having the structure as described above,
When changing towels, the tip of an unused towel must be set on the winding shaft, so it is necessary to wrap it multiple times.
Furthermore, 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, conventional towel dispensing machines have a structure in which the unused towel is placed on the bottom side so as not to obstruct the user's field of vision when putting on the towel, and the take-up roller on which the used towel is wrapped is placed on the top side. However, if such a towel arrangement was adopted, there was a problem in that germs and the like inevitably fell onto the unused towels located below, making the towels extremely unclean.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a cassette that is detachable from the main body, and a supply O-lamp with unused towels wrapped around the cassette in advance. We adopted a structure in which the towel is attached with the towel on the top and the take-up roller with the tip of the unused towel wrapped on the bottom.

[Function] When the above-described structure is adopted, the towel can be attached and detached with a single touch via the cassette, eliminating the troublesome task of attaching and detaching the towel.

In addition, it can be installed with the unused towel A on the top and the used towel on the bottom, and there is no chance of any germs falling off, making it extremely clean.

The large and small arcuate portions 42 and 44 are formed to face in the same direction and to be convex upward in the illustrated example.

The large arcuate portion 42 has approximately the same curvature as a fresh towel, and the small arcuate portion 44 has approximately the same curvature as the take-up roller 40.

Furthermore, a pair of upper and lower symmetrical arc-shaped protrusions 45, 45 are formed inwardly in the middle of the fixture 41.

A guide bar 37 is held between these projecting pieces 45 and 45.

Furthermore, a projecting piece 46 is provided at the upper end of the fixture 41 and extends upward in an L-shape.

This projecting piece 46 extends further upward from the upper end of the cassette 2,
It has a protrusion 4 that is large enough to surely touch the front edge of the top plate 5 of the main body 1.

Next, a method of using this embodiment configured as described above will be explained.

First, an unused towel 38 is attached to the cassette 2.

Since the unused towel 38 is already wrapped around the supply roller 39, the shafts 39a at both ends of the supply roller 39 are fitted into the elongated holes 34.

Next, pull out the tip of the unused towel and insert it into the guide bar 37.
It passes through the outside of the bottom plate 31, passes through the gap 32 from the bottom side of the bottom plate, and is wound several times around a winding roller 40 rotatably supported in the notch 35.

At this time, the unused towel pulled out is made to form an optimum loop length.

Next, the fixture 41 is attached. At this time, the large arcuate portion 42 is first pressed onto the upper side of the unused towel 38 located above, the small arcuate portion 44 is pressed together with the towel onto the upper side of the take-up roller 40, and the protruding piece is 45. Fit the guide bar 37 together with the towel between 45 and 45.

When the fixture 41 is attached in this way, the fixture 41
is fixed to the cassette 2 side via the guide bar 37 by the projecting pieces 45, 45, and the large and small arcuate portions 42.4
4 is elastically pressed against the unused towel 38 and the take-up roller 40.
Fix it to the cassette side.

With the unused towel attached, the cassette 1-2 is packaged in a plastic film bag or shrink-backed and delivered to the user.

The user unpacks the package and attaches the cassette 2 to the main body 1 of the dispensing machine fixed to the wall.

To do this, the cassette 2 is placed opposite the main body with the support frames 29 and 30 facing the main body, the protrusion 33 is placed above the protrusion 8, and the lower surface of the support frame 30 is placed above the support frame 9. Press fit into the main body 1 in this manner.

Then, the protrusion 13 of the lock lever 11 eventually touches the side plate 28.
．． 28, the O-tsu lever 11 is elastically deformed outward.

Then, when the protrusion 13 eventually gets over the side plate 28, it fits into the notch 36, and the cassette 2 is locked.

At this time, the spring 15 provided on the back plate 6 is elastically deformed and compressed.

Unused towels can be attached together with the cassette in one operation as described above.

At B'W of this cassette 2, the protruding piece 46 of the fixture 41 hits the front edge of the top plate 5 of the main body 1, and the unused towel 3
8. The take-up roller 40 and guide bar 30 are removed, and the fixture 41 is automatically removed.

In this state, the user wipes his hands using the front side of the looped unused towel, and after use, pulls the front side of the looped towel downward.

At this time, a downward load is applied to the unused towel, but since the axis of the unused towel and the axis of the drive rollers 3 and 4 are misaligned, no load is applied perpendicular to the axis of the drive roller 3. The weight at the time of pulling out functions as a rotational moment for the unused towel 38, and the towel is reliably pulled out.

When the towel is fed out, the unused towel 38 and the drive roller 3 come into contact with each other, the drive wJ row 53 rotates, and the gear 24.
The drive roller 4 is rotated via the drive roller 25, and the take-up roller 40 in contact with the drive roller 4 is rotated to wind up the used towel.

As the number of used towels to be wound up increases, the diameter of the used towels wound around the take-up roller 40 increases, and the drive rollers 3 and 4 are pushed up through the elongated hole 16, but the drive roller 3 is always unrolled. It is in contact with the used towel 38.

Therefore, used towels are wound up in an amount corresponding to the number of rows that have been pulled out, and the loop length is always maintained at a substantially constant length.

Use continues in this manner, and when all the unused towels are used up, the cassette 2 is removed and replaced with a new one.

In this case, push the front ends of the lock levers 11, 11 outward with your fingertips to remove the protrusion 13 from the edge of the notch 36 of the cassette 2.

Then, the spring 15 provided on the back plate 6 of the main body 1
extends and presses the edge of the support frame 29,30 so that the cassette 2
is pushed forward a predetermined distance.

After the cassette has been pushed out a predetermined distance, the cassette may be grasped by its side plates 28.degree. 28, pulled out from the main body 1, and replaced with a new cassette 2 as described above.

Note that the replaced used towel may be attached with the fixture 41 upside down to prevent it from rotating, and then returned by placing it in a plastic film bag or the like.

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.

[Effect] As is clear from the above description, according to the present invention, an unused towel is placed on the upper side of a cassette that is detachably attached to the main body side, and a take-up roller on which a used towel is wound is placed on the lower side. Because it has a structure in which the towels are installed on the side, the towels can be attached and removed using the cassette, making it extremely hygienic and easy to attach and detach.Moreover, since unused towels are located on the top, they can be removed from the used towel side. No inconveniences such as germs etc. falling will occur.

In addition, by using a fixing device, it is possible to hold unused towels and take-up rollers so that they do not rotate, and the loop can be fed in a constant state, making it extremely easy to handle before installation or after removal. becomes.
