Description

[Detailed Description of the Invention] The present invention relates to a towel dispensing machine, and more specifically to a towel dispensing machine configured to prevent the towel from being pulled out too much or rolled up too much when the towel is being pulled out. be.

Conventionally, a long towel wound in a roll is stored, the towel is brought out to a position where the user can use it, and the user pulls the side edge of the towel with both hands to pull the towel a predetermined distance. There is a known towel dispensing machine that can pull out used towels one by one and wind up used towels corresponding to the number of towels pulled out.

This type of towel dispensing machine is provided with an interlocking mechanism using a belt or chain so that the pulling side and the winding side are interlocked.

However, the force with which a user pulls out a towel differs from person to person, and if the interlocking mechanism is configured based on the average pulling force, when the towel is pulled out with a large force, the towel will not be pulled out due to inertia force. The problem is that the interlocking mechanism operates even after the towel is finished, resulting in the towel being fed out too much or rolled up too much.

This invention was made to eliminate the above-mentioned drawbacks of the conventional technology, such as over-feeding of towels,
To provide a towel dispensing machine configured to prevent excessive winding.

The details of the present invention will be explained below based on the embodiments shown in the drawings.

Fig. 1 and the following are for explaining one embodiment of the present invention, in which the towel dispensing machine, which is generally indicated by the reference numeral 1, has protrusions 2a and 2b that protrude in semicircular shapes in two stages upward and downward toward the front. A cover 3 having an arcuate cross-section that can be opened and closed is provided on the front side of the lower protrusions 2b and 2b.

The cover 3 opens and closes its lower end via a hinge 4 made of synthetic resin or the like to the lower end of the arc-shaped side wall 5 that constitutes the latter half of the storage space for rolled towels, which is suspended between the left and right side plates 2, 2. freely connected.

An arcuate protrusion 6 is formed along the periphery of the inner surface of the arcuate protrusions 2b, 2b. This protrusion 6 serves as a guide when the cover 3 is closed, and as is clear from FIGS. 2 and 3, this protrusion 6 is formed over approximately 180 degrees, and its upper end reaches near the upper end of the protrusion 2b on the near side, and a protrusion 7 is formed on the inner side of the protrusion 2c that is continuous with the protrusion 2b and is formed near the upper end. .

A gap is formed between the projection 7 and the upper end of the protrusion 6, into which the cover 3 can fit.

Therefore, when the cover 3 is closed, the tip of the cover 3 enters the gap between the tip of the protrusion 6 and the protrusion 7, as shown in FIG. 3, and clamps the free end of the cover 3. The cover 3 can be locked to prevent it from opening.

The cover 3 and the arc-shaped side wall 5 work together to form a space for accommodating a rolled towel, but there is a sufficient gap 8 between the tip of the cover 3 and the tip of the side wall 5, so that the cover 3 can be Even in the closed state, the towel can be pulled out from this gap 8 as described later.

By the way, a roller 9 is rotatably supported above the protrusion 7 and at a position corresponding to the gap 8 between the left and right bulges 2c, 2c.

As shown in FIG. 1, a belt-shaped friction member 10 such as rubber is wound spirally around the surface of the roller 9 at a predetermined pitch.

Note that a notch 5a is provided at the center of the upper end of the side wall 5.
is formed.

On the other hand, an arc-shaped cover 11 is attached to the front side between the upper protrusions 2a, 2a so as to be openable and closable. This cover 11 is cover 11
A hinge 13 made of synthetic resin or the like is attached to the tip of the lower end of an arc-shaped side wall 12, which forms a space for accommodating used towels.

The arc-shaped side wall 12 is continuous with the upper ends of the left and right side plates 2, 2, but as shown in FIG. 2, a gap 14 is formed at its lower part over the entire length.

A locking member 15 made of a leaf spring or the like is fixed to the upper end of the side wall 12 to lock the free end of the cover 11.

Further, as shown in FIG. 1, a backing plate 12a is fixed to the inner side of the upper end of the side wall 12 over its entire length, and its tip protrudes slightly toward the front side.

This backing plate 12a serves to catch the tip of the cover 11 when the cover 11 is closed.

Furthermore, a notch 12b is formed at the lower end of the side wall 12 and at the center in the longitudinal direction.

On the other hand, a roller 16 is rotatably supported between the side plates 2, with the roller 16 slightly fitted inside the side wall 12 through a gap 14 formed at the lower part of the side wall 12. This roller 16 is parallel to the roller 9, and has a belt-shaped friction member 10 wound helically around its circumferential surface.

Further, two protrusions 1 are perpendicular to the inner surfaces of the side plates 2, 2, and are arranged in the center of the circular space formed by the arc-shaped cover 11 and the side wall 12.
7 and 18 are protruded apart from each other by a predetermined distance. Among these protrusions, the protrusion 18 located closer to the cover 11 side is shorter than the other protrusions 17, and a slope 18a is formed at the corner on the protrusion 18 side.

Between these protrusions 17 and 18, there is a symbol 19 in FIG.
Support shafts 19a protruding from both ends of the towel take-up roller are rotatably and slidably fitted.

Furthermore, support shafts 20 are provided in a protruding manner on the outside of the upper end portions of the left and right side walls 2, 2 and at positions corresponding to the center portions of the arcuate projections 2a.

By the way, at the outer ends of the two rollers 9, 16, there are sprockets 21,
22 is fixed. One sprocket 21
The diameter of the sprocket is smaller than that of the other sprocket 22, and a belt 23 is stretched between the two.

Therefore, as will be described later, when the roller 9 is rotated when drawing out the towel, the roller 16 is also rotated via the belt 23.

A support plate 24 is installed on the outside of one sprocket 22.
is located. The lower end of the support plate 24 is fixed to the side plate 2 side, and the middle part of the upper end part is fitted into the support shaft 16a of the roller 16, and is prevented from coming off by a C ring 25. The washer 2 is placed in contact with the outer surface of the support plate 24 and the sprocket 22.
An elastic body 27 is loaded between the body 6 and the body 6.

The elastic force of this elastic body 27 is applied to the sprocket 22,
Therefore, this acts as a braking force on the rotation of the fixed roller 16, and can prevent the rollers 9 and 16 from rotating excessively when the towel is pulled out.

Incidentally, the braking mechanism consisting of the support plate 24 and the elastic body 27 may be provided on the side of the small diameter sprocket 21, as shown by the chain line in FIG.

On the other hand, reference numeral 28 denotes a support frame, which is formed into a flat U-shape as shown in FIG.
A notch 29a is formed into which the 0 is rotatably fitted.

This support frame 28 is fixed to a wall surface with screws or the like, and serves to support the towel dispensing machine 1 as a whole.

Note that it is not only the belt 23 that is suspended between the sprockets 21 and 22, but also a chain 30 as shown in FIG. 6. At this time, chain sprockets may be used as the sprockets 21 and 22.

Next, the usage and operation of the towel dispensing machine according to the present invention constructed as above will be explained.

First, when it is desired to attach the towel 31, the upper and lower covers 3 and 11 are opened as shown in FIG.

In this state, the cover 3 is closed with the rolled towel 31 placed on the inside of the cover 3.
When the cover 3 is closed, the cover 3 is closed along the outside of the protrusion 6, and its tip side is fitted between the protrusion 6 and the protrusion 7 and locked.

In this state, the tip of the rolled towel 31 is pulled out from the gap 8 between the tip of the cover 3 and the side wall 5, and guided downward along the outside of the cover 3 while attached to the roller 9, and pulled out to the outside of the side wall 5. From there, it is brought into contact with rollers 16 and introduced into the circular space formed by cover 11 and side wall 12.

At this time, since the cover 11 is open, the take-up roller 19 of the towel 31 can be easily inserted between the protrusions 17 and 18.

Since the protrusion 18 on the front side is low in height, the winding roller 19 can be easily attached.

The towel 31 attached to the roller 16 and guided to the winding roller 19 mounted in this way
Wrap the tip and secure.

With the towel 31 fixed, the take-up roller 19
When you release the winding roller 19, the protrusion 1 is pulled down by its own weight.
7 and 18 and comes into contact with the roller 16.

When the cover 11 is closed in this state, its tip is locked between the locking member 15 and the backing plate 12a.

When attaching the towel 31 in this way, the towel 31 must be guided to the back side of the dispensing machine, but this work is troublesome because the space between the wall surface and the towel dispensing machine 1 is small. In this case, the towel dispensing machine 1 is attached to the support frame 2 via the support shaft 20 at the upper end.
Since it is suspended from 8, it can be rotated freely.

Therefore, the space on the back side of the towel dispensing machine 1 can be widely used, and the task of attaching towels becomes extremely easy.

After the towel 31 is attached in this way, if the towel 31 is pulled downward as shown in FIG. 3, the frictional force between the friction member 10 and the towel 31 is extremely large, so the roller is rotated.

As a result, the roller 16 is rotated via the sprocket 21, the transmission band 23, and the sprocket 22.

Then, the take-up roller 19, which is in contact with the roller 16 via the friction member 10, is rotated in the opposite direction to the roller 16 as shown by the arrow in FIG. 3, and the towel 31 begins to be taken up.

In this way, each time the towel 31 is pulled out to wipe hands, the used towel is sequentially rolled up and stored in the towel dispensing machine.

After all the towels 31 are used, the upper cover 11 is opened, the used towels 31 are taken out, and the towels 31 are replaced with new ones.

By the way, even if a large force is applied to pull out the towel 31, since the braking force by the elastic body 27 is applied to at least one sprocket 22, the rollers 9 and 16 will rotate too much due to inertia, resulting in excess towel being pulled out. It is not pulled out or wound up excessively.

Although a spring is used as the elastic body 27 in the above, an elastic body such as an elastomer may also be used, and in general, any elastic body can achieve the rotation suppression that is the purpose of the present invention. can do.

As is clear from the above description, according to the present invention, a braking force is generated by pressing the outer surface of at least one sprocket of an interlocking mechanism consisting of a belt or chain and a set of sprockets on which these are stretched, by means of an elastic body. Since the interlocking mechanism does not rotate due to inertia, the towel is not fed out too much, the towel is not wound up too much, and the towel is not wasted.
