Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a towel dispensing machine, and more particularly to a gusset type towel dispensing machine in which towels can be attached and detached, transported, and stored using a cassette. It is.

[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. A towel dispensing machine is known that has a structure that winds up a used portion and always maintains a loop.

In such a towel dispensing machine, a supply roller on which unused towels are wrapped and a numbered roller and a take-up roller on which used towels are wrapped are arranged above and below, and the roller can be freely rotated and moved up and down between them. A pair of upper and lower drive rollers are arranged in a freely interlocking relationship, with the upper drive roller in contact with the outer circumferential surface of the unused towel and the lower drive roller in contact with the outer circumferential surface of the used towel. has been done.

Therefore, when an unused towel is pulled out, the take-up roller is rotated via a pair of upper and lower drive rollers that are 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.

Furthermore, in the past, the user had to manually attach an unused towel and remove a used towel, which caused problems in that attaching and detaching was troublesome and unhygienic.

[Means for Solving the Problems] In order to solve the above-mentioned problems, in the present invention, the unused towel wound around the supply roller and the winding roller around which the tip of the unused towel is wound are arranged in advance. A rolled up cassette is provided, and a structure is adopted in which the towel can be attached to and removed from the main body via this cassette.

An arcuate portion 44 is formed. ``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, 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 m that is sufficient to reliably contact 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, attach the fixture 41. At this time, first press the large arc-shaped part 42 onto the upper side of the unused towel 38 located above, and then push the small arc-shaped part 44 together with the towel onto the upper side of the take-up roller 40. , the guide bar 37 is fitted together with the towel between the projecting pieces 45, 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, fixing the unused towel 38 and the take-up roller 40 to the cassette side.

In this manner, the cassette 2 with the unused towel attached 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.

At this time, the cassette 2 is placed opposite the main body with the supporting frames 29 and 30 facing the main body, the protruding piece 33 is positioned above the protruding piece 8, and the lower surface of the supporting frame 30 is positioned above the supporting frame 9. press fit into the main body 1.

Then, the protrusion 13 of the lock lever 11 eventually touches the side plate 28.
, 28, and the lock 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.

Above) You can attach (pull) an unused towel along with the cassette in one operation.

When the cassette 2 is installed, the protrusion 46 of the fixture 41 hits the front edge of the top plate 5 of the main body 1, and the unused towel 38 is inserted between the large and small arcuate portions 42, 44 and the protrusions 45, 45.
, the take-up roller 40 and guide bar 30 come off, 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 force 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 53. 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 this towel is fed out, the unused towel 38 and the drive roller 3 are in contact with each other, the drive roller 3 rotates, and the gear 24.2
The drive row 54 is rotated via the roller 5, and the take-up roller 40 in contact with the drive row 54 is rotated to wind up the used towel.

As the number of times the used towel is wound increases, the diameter of the used towel wound around the winding roller 40 increases, and the drive roller 3.4 is 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 corresponding to the number of pulled out m are wound up, 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.

It should be noted that the present invention is not limited to the above embodiments, but includes within its scope various modifications, stage 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, the towel is attached in advance to a cassette that can be attached to and detached from the main body, so all operations for attaching and detaching the towel to and from the main body can only be done via the cassette. It is extremely hygienic as there is no need to touch the towel directly.
