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 towels from being pulled out or rolled up too much when pulling out towels. 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 a chain so that the pulling-out side and the winding-up side are interlocked.

However, the force with which a user pulls out a towel is different for each user, 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 on the inner side of the arcuate protrusions 2b, 2b along the peripheral edge thereof. 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 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 walls 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 22 is smaller than that of the other sprocket 22, and a transmission band 23 is stretched between the two sprockets.

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

On the outer surface of the side plate 2 and in contact with the outer peripheral surface of the sprocket 22, a substantially V-shaped elastic body 25 is fixed at its base with screws 24 in an upwardly open state.

One end 25a of the elastic body 25 is in contact with a pin 26 protruding from the outer surface of the side plate 2, and a friction member 25c is fixed to the tip of the other end 25b. It is in contact with the outer surface of 23.

As a result, the transmission band member 23 is constantly applied with a braking force when traveling, and is restricted from freely traveling.

In addition, there are multiple pins 26 in a row on the left and right, and the elastic body 2
The magnitude of the braking force applied to the transmission band 23 can be adjusted by selecting which pin the one end 25a of the transmission band 23 contacts.

On the other hand, the support frame 27 is fixed to the wall side with screws or the like.

The support frame 27 has arms 28 at both ends thereof, and a notch 28a is formed above the tip of each arm 28, and the support shaft 20 is rotatably fitted into the notch 28a.

Therefore, the entire towel dispensing machine 1 can freely rotate around the support shaft 20.

Although the transmission band 23 stretched between the sprockets 21 and 22 is shown as a belt in the illustration, it may be a chain.

In other words, any endless band can be used as the power transmission means.

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 roll-shaped 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. It is brought into contact with the roller 16 from the outside and guided into the circular space formed by the cover 11 and the 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 that has been guided in contact with the roller 16 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.
7, so 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 manner, 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 that the roller 9 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 when pulling out the towel 31, the braking force from the elastic body 25 is applied to the transmission band 23, so the rollers 9 and 16 will not rotate too much due to inertia, and the towel will be pulled out. 31 is not fed out or wound up excessively.

In addition, since the elastic body 25 that applies the braking force is in contact with the loose side of the transmission band 23, which is an endless band, it does not prevent the normal running of the chain or belt, which is the transmission band, and only applies the braking force. can be given.

By the way, FIG. 4 explains another embodiment of the present invention, in which the elastic body 25 is provided not only on the sprocket 22 side but also on the other sprocket 21 side.

By providing two elastic bodies 25 in this way, the braking force can be made to act even larger.

In the above embodiment, a subring was used as the elastic body 25, but an elastic body such as an elastomer may also be used, and generally any elastic body can suppress rotation, which is the purpose of the present invention. can be achieved.

As is clear from the above description, according to the present invention, a braking force is applied by an elastic body to the outer peripheral surface of the transmission band, which is an endless band that is a power transmission means between the rollers on the towel delivery side and the towel take-up side. Since this structure adopts a structure that gives the towel a large amount of force, even if the towel is pulled out with a large force, the roller can be prevented from rotating due to inertia, and the towel will not be unnecessarily fed out or wound up, and the towel will not be wasted.
