Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a towel dispensing device, and more particularly to a towel dispensing device that incorporates a towel roll, that is, a long strip of towel, and a position where the unused portion of the towel is distributed for the user to use. This relates to a type of towel dispensing device that sends out towels and winds up the used portion inside.

A conventional continuous towel dispenser is shown in FIGS. 1 and 2. This towel dispenser, generally designated by the reference numeral 1 in each figure, has a rectangular casing consisting of a flat rear wall 2 and a pair of side walls 3.4 extending perpendicularly from both ends of the rear wall 2. have

In use, the towel dispenser N1 is mounted such that the rear wall 2 is flush with the mounting wall and the side W3.4 is vertical.

side! 3.4 A towel feed roller 5 is placed in front of the roller 4, and a towel take-up roller 6 of the same diameter is placed slightly behind the roller 5 horizontally. These rollers5.

! ! 3 and is fixed to the sprocket 7.8 on the outside of the side wall 3. A chain 9 is attached to the sprocket 7.8, and as a result, the towel delivery roller 5
And the towel take-up roller 6 is 3'l! It is designed to move.

Usually, a roller rotation stopper (not shown) is attached to the towel delivery roller 5, so that the rotation of the roller 5 is stopped after rotation at a predetermined number of rotations.

Towel feed roller 5 and towel winding roller 6
A circular hole 10 and a diagonal notch 11 are provided above the side ri 3 and 4, respectively.

A scissor roller 12 is passed through the irregularly shaped hole 10, and a used towel shaft 13 is passed through the diagonal cutter 11 in parallel with the towel delivery roller 5 and the towel take-up roller 6, respectively. The scissor roller 12 and the used towel shaft 13 are simply inserted into the hole 10 and the cutout 11 with their short shafts protruding from both ends, respectively, so they can be moved freely inside the hole 10 and the cutout 11, respectively. I can do it. When the scissor roller 12 and the used towel shaft 13 are in contact with the bottom of the hole 10 and the cutout 11, respectively, they are brought into close contact with the towel delivery roller 5 and the towel take-up roller 6, respectively. .

The surfaces of the above-mentioned towel delivery roller 5 and towel take-up roller 6 are covered with a friction coating 1i14, so that they frictionally engage with the towel, as will be described later.

At the lowest part of the side wall 3.4 there is an arched towel bed 1.

covered by.

Next, the conventional towel dispenser 1 configured as described above will be described.
The operation will be explained using FIG.

In the figure, a roll of unused towels designated by reference numeral 16 is set on the curved bottom of the towel bed 15. The starting end of the unused towel starts from this towel roll 16, passes between the towel feed roller 5 and the scissors roller 12, wraps around the scissors roller 12, and then unloads the towel from between the scissors roller 12 and the protection plate 19. Exposure position j! 1
7/\ is pulled out. The insurance board indicated by the symbol @19 is l! on the axis indicated by the symbol 20! It is attached to the III walls 3 and 4 and can be rotated around an axis 2o. Therefore,
When pulling out the starting end of the towel, make sure that it has an appropriate amount of slack at the towel exposed position IF117 so that it does not become loose.
It passes between the oblique A-ru shielding plate 21 and is fixed to the used towel residue 13.

In the towel dispenser 1 set in this way, when the user pulls the towel in the towel exposed position 11 in the direction of the arrow Δ, the scissor roller 12 is pressed against the towel delivery roller 5, and the roller 5 P7! Since the towel is covered with rubbing buds 14, it rotates without slipping as the towel is pulled out. The rotation of the towel delivery roller 5 is transmitted to the towel take-up roller 6 by a chain 9, and since this roller 6 is also covered with an abrasion coating 14, the towel wrapped around the roller 6 is prevented from being wound due to its own weight. The used towel shaft 13 also rotates without slipping. By the rotation of the used towel shaft 13, the used towel at the towel exposed position 17 is drawn into the towel dispenser, flattened by the inclined towel blocking plate 21, and wound around the used towel shaft 13. At this time,
Towel feed roller 5 and towel winding roller 6
sprockets 7 and 8 that have the same diameter and are connected to them.
Since they have the same number of teeth, the length of the sent out towel is equal to the length of the rolled up towel, and the slack of the towel at the towel exposed position 17 is kept constant.

However, since this constancy changes due to slipping of the towel, etc., various measures may be taken, such as making the numbers of teeth of the sprockets 7 and 8 different.

As explained above, in the conventional towel dispenser 1, the user uses the action of pulling out an unused towel to
He was rolling up used towels. As a result, once the end of the towel is pulled out, the towel can no longer be rolled up, and the end of the towel remains hanging outside the towel dispenser.

And the towel was left hanging! Not only is it unsightly, but because there are no unused towels, the area is used over and over again, and dirt piles up on top of each other, resulting in an extremely filthy condition.

In addition, the hanging towels also come into contact with the wall surface on which the towel dispenser 1 is mounted, which further accelerates uncleanliness.

Furthermore, extreme stains on the ends cannot be removed with just one wash, and the entire towel often has to be rewashed just for the stains on the ends. This has led to increased towel cleaning costs and decreased towel life.

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide a towel dispenser that can automatically wind up the end of a towel.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

Figures 3 to 9 illustrate one embodiment of the present invention.
In the figure, the same parts as in FIGS. 1 and 2 are denoted by the same reference numerals, and the explanation thereof will be omitted.

First, the present invention will be explained in detail using FIGS. 3 and 4.

In the figure, what is generally designated by the reference numeral 22 is a sensor that detects the end of the towel. In the sensor 22,
Reference numeral 23 indicates a sensor board, and a sensor arm 24 is attached to this sensor board 23 with a support shaft 26, and is pressed against the sensor board 23 by the elasticity of a spring 27. A sensor roller 25 is attached to the tip of the sensor arm 24, and a rectangular hole 23a is cut out in the portion of the sensor board 23 that the sensor roller 25 contacts.

The sensor 22 is installed horizontally below the scissors roller 12, and when in use, the towel is sandwiched between the sensor substrate 23 of the sensor 22 and the sensor roller 25 at an intermediate position between the scissors roller 12 and the towel exposed position 11. do. That is, the sensor 22 prevents the sensor roller 25 from being pushed into the rectangular hole 23a of the sensor board 23 by the towel while an unused towel remains, but if the end of the towel is pulled out, The sensor roller 25 is inserted into the rectangular hole 2 of the sensor board 23.
3a, the sensor arm 24 pivots around the fulcrum 26, and this movement is used to activate a power spring, which will be described later. T like this! ! The sensor 22 senses the end of the towel III by l1ffi.

I3 in the figure, which is not entirely designated by the reference numeral 28, is a gearbox, which includes a pin mechanism activated by a sensor,
A mechanical part and ' for transmitting the unlocking force of the mainspring to the towel winding roller 6 are housed. The reference numeral 29 is a knob for winding the mainspring.

Next, details of the gearbox 28 will be explained using FIGS. 5 and 6.

In the figure, the one indicated by the reference numeral 30 is a mainspring. A ratchet wheel 31 and a knob 29 are fixed to a rotating shaft 30a to which the inner end of the mainspring 30 is fixed, and a gear 32 is also fixed to the shaft 30a, although it is not fixed.
is also installed.

The gear 32 is provided with a tooth stop 33 and a spring 34, and the tooth stop 33 is connected to the ratchet wheel 3 by the spring 34.
It is pressed against the teeth of 1.

Therefore, when the ratchet wheel 31 is rotated in the direction of winding up the mainspring, the pawl 33 does not catch on the teeth of the wheel 31, but when it is rotated in the opposite direction, it does. When the mainspring 30 is wound up, the rotation of the ratchet wheel 31 is not transmitted to the gear 32, and when the mainspring 30 is unlocked, the rotation of the ratchet wheel 31 is transmitted to the gear 32.

Gears 35 and 36, gears 37 and 38, and gears 39 and 40 are pairs of gears with a small number of teeth and gears with a number of canine teeth, and are fixed on the same axis, and the gear 41 is a gear with a small number of teeth. It is fixed coaxially with the final wheel 42. These gears are gears 32 and 35, gears 36 and 37, gears 38 and 39, and gears 40 and 41, which are in mesh with each other, and speed up the rotation of the gear 32 when the mainspring 30 is unlocked. There is work.

For example, for the sake of simplicity, assume that the ratio of the number of teeth of four pairs of gears: gear 32 and gear 35, gear 36 and gear 37, gear 38 and gear 39, and gear 40 and gear 41 is all equal to 5:1. While the gear 32 rotates once, the gears 35 and 3G rotate 5 times, the gears 37 and 38 rotate 25 times, the gears 39 and 40 rotate 125 times, and the gear 41 and the final wheel 42 rotate 6 times.
This will result in 25 rotations. On the contrary, this means that the mainspring 3
This means that rotation of the final wheel 42 due to an unlocking force of 0 can be stopped with an extremely small force. If the final wheel 42 cannot be rotated, the mainspring 30 cannot be unlocked either.

Therefore, the rotation of the final wheel 42 is prevented by the stopper 43, thereby preventing the mainspring from unwinding. This stopper 43 is attached to one end of the sensor arm 24, and when the sensor arm 22 senses that the end of the towel has passed, the sensor arm 24 moves in the direction of arrow B.The stopper 43 is removed from the final wheel 42.
Mainspring 30 begins to release. That is, the sensor 22 activates the mainspring 30 by such a mechanism.

The gear indicated by the reference numeral 44 in the figure meshes with the gear 36,
It is fixed to a gear shaft 45. gear! rilI45 is a one-way latch portion 48 formed on the sprocket 47.
It is connected to the sprocket 41 via.

The details of the one-way clutch section 48 will be described later, but here, the rotation of the gear shaft 45 is transmitted to the sprocket 47, and the rotation of the sprocket 47 is transmitted to the gear shaft 45. A chain 9 runs over the sprocket 47, so that the sprocket 47 interlocks with the sprocket 7.8. That is, when the stopper 43 is removed by the sensor 22 and the mainspring 30 is activated, the unlocking force is applied to the ratchet wheel 31, the gear 32, and the gear 35.
, gear 36, gear 44, gear shaft 45, sprocket 47
, chain 9, and sprocket 8 one after another to rotate the towel take-up roller 6.

Here, the necessity and mechanism of the one-way clutch section 48 will be explained. The purpose of the present invention is to wind up the end (1) of a towel, and for this purpose, in this embodiment, there are three A second sprocket 41 is inserted, and the unlocking force of the mainspring 30 is transmitted to the sprockets 1 to 47.By the way, the sprocket 47 must be able to rotate freely except when winding the towel l?+q. Yes, because if the sprocket 47 was not free, the chain 9 would not be able to turn, and the towel would not be able to be constantly fed out and rolled up.Therefore, in the present invention, the gear shaft 45 is A one-way ludge is used in which the rotation is transmitted to the sprocket 47, but the rotation of the sprocket 41 is not transmitted to the gear @45.

The type of one-sided clutch is ratchet wheel 3.
1 and the gear 32, such as a ratchet 1 type or a coil spring type, but in this embodiment, a bottle roller type one-sided clutch is used. The explanation will be given below using FIG. 7.

What is indicated by the reference numeral 48 in the figure is the one-way clutch portion of the sprocket 41. A hole having the shape shown in the figure is cut out in the center of the one-way clutch portion 48, and the pin shaft 4
5, some wedge-shaped gaps 53 remain. Cylindrical clutch roller pins 49 are inserted into the wedge-shaped gaps 53, and the clutch roller pins 49 are inserted into the wedge-shaped gaps 1l153.
The diameter is large enough to allow some movement inside. In the one-way clutch configured in this way, the one-way clutch portion 4
8 in the direction of arrow C as shown in FIG.
3, the gear shaft 45 is only in contact with the one-way latch portion 48, and its rotation is not transmitted thereto. However, when the gear shaft 45 is rotated in the direction of the arrow as shown in FIG. , the gear shaft 45, the latch roller bin 49, and the one-way latch portion 48 rotate together.

The parts indicated by numerals 30 to 50 described above on j″4 are as follows:
It is housed in a chassis 51, 52 with bearings forming a gearbox 28.

Next, the operation of the present invention configured as described above will be explained using FIGS. 8 and 9.

To load the towel, use the scissor roller 12 and the towel mist roller 1.
11!17, the sensor group 1D2 of the sensor 22
The procedure is the same as before, except that a towel is passed between the roller 3 and the sensor roller 25. After loading the towel, stopper 43
Make sure that it is placed on the final wheel 42, and wind the mainspring 30, and the machine is ready for use.

FIG. 8 explains the operation when an unused towel remains in the present invention. In this state, the sensor roller 25 is not pushed into the hole in the sensor board 23, and the stopper 43 is not inserted into the final wheel 42. Since it remains engaged, the mainspring 30 does not operate. Therefore, the operation of the present invention at this time is exactly the same as before, except that the chain 9 is connected to the sprocket 47, which can rotate freely by the action of the one-way clutch, so a description thereof will be omitted.

FIG. 9 explains the operation when the end of the towel is pulled out in the present invention. At the moment when the end of the towel is pulled out, the sensor roller 25 of the sensor 22 is pushed into the hole 23a of the sensor substrate 23, and the sensor arm 24 rotates around the fulcrum 26. Then stopper 4
3 comes off the final wheel 42 and the mainspring 30 begins to unlock. The unlocking force of the mainspring 30 is transmitted to the towel winding roller 6 through the above-mentioned path, and the hanging end of the towel is completely wound up by the time the mainspring 30 is completely loosened and unlocking stops.

Through the above series of operations, when the end of the towel is pulled out, its I? ′! The ends can be rolled up.

As is clear from the above description, the towel dispenser of the present invention includes a sensor that detects the end of the towel, a spring activated by a sensor, and a spring that transmits the unlocking force of the spring to the towel take-up roller. Since it has a towel end winder ml consisting of a mechanical part using a one-way clutch, it is possible to obtain the effect that the end of the towel can be automatically wound into the towel dispenser.

This not only protects the end of the towel from excessive dirt and keeps the towel dispenser clean, but also reduces towel cleaning costs, extends towel life, and reduces power consumption. Because it uses a power bank, running costs such as electricity costs are completely eliminated, which is impressive.
