Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roll towel cabinet configured to feed out unused roll towels for use and to wind up used roll towels. It is.

[Prior Art] A roll towel cabinet must have the ability to roll up a used roll towel by the same length when an unused roll towel is pulled out.

In order to perform the above functions, a roll towel cabinet generally includes a driven roller that is brought into sliding contact with an unused rolled towel and rotated by pulling out the unused towel, and a drive that is directly connected to the driven roller. A gear, a driven gear rotated by the above drive gear, and a drive roller driven by the above driven gear to rotate and wind up the used roll towel while slidingly touching the used roll towel. .

FIG. 2 is an explanatory diagram schematically showing a vertical cross section of a conventional roll towel cabinet, in which a main body portion 1 of the roll towel cabinet is attached to a wall 2. As shown in FIG.

The main body part 1 stores an unused rolled towel 3, and one end of the unused rolled towel 3 is sandwiched between a driven roller 4 and a pinch roller 5, and the unused rolled towel 3 is held in the main body part 1.
It is pulled out from window 1a as shown by arrow A.

The unused rolled towel pulled out from the window 1a is hung in a loop 6 for use, and the used part is pulled out from the window 1b to the main body 1 as shown by arrow B.
It is pulled into the container and wound up as shown in the figure 7.

The above-mentioned winding operation of the used roll towel 7 is performed as follows.

When the unused roll towel 3 is pulled out as shown by arrow A, the driven roller 4 around which it is wrapped and in sliding contact rotates clockwise in the figure. A sprocket 8 as a drive gear is fixed concentrically to the driven roller 4, and this drive gear 8 also rotates clockwise.

The clockwise rotation of the drive gear 8 is transmitted to the chain 9 and the sprocket-shaped driven gear 10, causing the driven gear and the drive roller 11 fixed thereto to rotate clockwise.

The used roll towel (indicated by a solid line) 7 is
It is placed on the drive roller 11 and is in sliding contact with the drive roller 11. Therefore, the used roll towel 7 is rotated counterclockwise by the clockwise rotation of the drive roller 11, and the used portion of the roll towel is wound up.

FIG. 3 shows a conventional example different from the above-mentioned one, and the same drawing reference numbers as in FIG. 2 are given to the same or similar structural members as in the above-mentioned conventional example. Further, the reference numbers in FIG. 2 with dashes attached are members corresponding to the constituent members of the conventional example. This conventional example (Fig. 3) is different from the conventional example (Fig. 2).
The main difference from the one shown in FIG. 1 is that the used roll towel 7 is disposed diagonally below the drive roller 11, and that the chain 9' is accordingly longer. In this example (Fig. 3), the used roll towel 7 is transferred to the drive roller 1.
1 is provided with spring means (not shown) that biases it in the direction of sliding contact.

In both of the above two conventional examples (FIGS. 2 and 3), the axial center position of the drive roller 11 is immovable with respect to the main body portions 1 and 1'. However, the diameter of the used roll towel 7 increases as it is used. Therefore, the axial center position of the used roll towel 7 cannot be fixed. For this reason, a bearing (not shown) for the used roll towel 7 must be movably supported, and the axial center position must be configured to move as indicated by arrow D as the diameter of the roll towel 7 increases. It won't happen. 7′ shown by the chain line is
It shows the size and position when its diameter is at its maximum.

As mentioned above, in the conventional technology, it is necessary to provide a means for guiding the used roll towel, its winding shaft, and winding bearing so that they can move in the direction of arrow D, which requires a large number of component parts and is difficult to follow. This makes the entire roll towel cabinet large and heavy, resulting in high costs. In addition, if a used roll towel is removed and an unused roll towel is supplied, 1 of the unused roll towel is supplied.
The operation of attaching the end to the used roll towel winding shaft is difficult.

[Problem that the invention seeks to solve]

By solving the above problems and eliminating the need to move the axis of the used roll towel shaft relative to the main body, the roll towel cabinet can be made smaller and lighter.
In addition, in order to reduce costs, a tilting arm member rotatably supports the driven roller shaft, the drive gear shaft, the driven gear shaft, and the drive roller shaft. A conceivable configuration (hereinafter referred to as a draft plan) is that the driven roller is tiltably supported by a support shaft and is pressed against the used roll towel by the weight of the tilting arm and the member attached thereto.

With the above improvement, the drive roller moves as the tilting arm tilts, but the driven roller does not move, so the used roll towel can be removed without affecting the rotational action of the driven roller when the unused roll towel is pulled out. The drive roller moves according to the increase in the diameter of the towel, and the winding action can be performed without changing the axial center position of the used roll towel.

FIG. 4 is an explanatory view schematically depicting a vertical cross section of the roll towel cabinet of the above-mentioned proposal.

The used roll towel of this draft is manufactured by a winding shaft 7 supported by a bearing (not shown) fixed to the main body 1.
It has a structure in which it is wound up by a.

Therefore, the used roll towel 7 at the beginning of rolling
(solid line) and the used roll towel 7' (dashed line) at the end of winding represent concentric circles.

A movable arm 12 is configured to be tiltably supported by the central axis of the driven roller 4, a driven gear 10 is mounted on the movable arm 12, and a chain 9'' is wound between the movable arm 12 and the drive gear 8 for transmission.
A first stage drive roller 11'' is fixed concentrically with the drive gear 8, and a final stage drive roller 14 is driven via an intermediate roller 13.

Since the movable arm 12 is tiltably supported, it tends to rotate clockwise in the figure due to gravity. Therefore, when the used roll towel has a small diameter as shown by the solid line 7, the movable arm 12 assumes the posture shown by the solid line and presses the final stage drive roller 14 against the used roll towel 7.

When the unused roll towel 3 is pulled out as shown by arrow A, the driven roller 4 is rotated counterclockwise in the figure, and the drive gear 8, chain 9'', driven gear 10, first stage drive roller 11', and final stage drive are rotated. The rollers 14 are each rotated counterclockwise.As a result, the final stage drive roller 14 rotates the used roll towel 7 clockwise to perform a winding action in the direction of arrow B.

As the diameter of the used roll towel 7 gradually increases, the final stage drive roller 14 is pushed up in the direction of the arcuate arrow E. When the diameter of the used roll towel is increased as indicated by the chain line 7', the movable arm is at the position of the imaginary line 12', and the final stage drive roller is at the position of the imaginary line 14'.

As described above, the device of this prototype (FIG. 4) functions to wind up a used roll towel in response to the withdrawal of an unused roll towel, without moving the winding shaft 7a of the used roll towel. Therefore, it is sufficient that the bearing supporting the winding shaft 7a is fixed to the main body 1'', and there is no need to guide it in a movable manner.

As a result of repeated practical tests on the proposed device (Fig. 4), the present inventor found that there is no need to move the axis of the used roll towel shaft relative to the main body, and the roll towel cabinet can be made smaller. Although it was confirmed that it was effective in reducing weight, the way the used roll towels (7' and 7) were wound was loose.
We encountered the problem that the towel could not be rolled up tightly (the used roll towel 7' in the final rolled-up state became limp).

The present invention has been made in view of the above-mentioned circumstances, and the used roll towel can be wound to an appropriate firmness without sacrificing the advantage of the proposed idea that there is no need to move the used roll towel shaft relative to the main body. The purpose of the present invention is to provide a roll towel cabinet that can be used easily.

[Means for solving problems]

In order to achieve the above object, the roll towel cabinet of the present invention includes a driven roller around which an unused rolled towel is wound and rotated by pulling out the unused towel, and a driven roller that is directly connected to the driven roller. a driven gear rotated by the drive gear, and a drive roller driven by the driven gear to rotate and wind up the used roll towel while slidingly touching the used roll towel. In the roll towel cabinet, a tilting arm member rotatably supports the driven roller shaft, the drive gear shaft, the driven gear shaft, and the drive roller shaft, and the tilting arm is connected to the driven roller shaft. The drive roller is tiltably supported by a concentric support shaft, and the drive roller is pressed against the used roll towel by the weight of the tilting arm and the member attached thereto. The invention is characterized in that a brake means is provided in the middle of the path of winding.

[Effect]

According to the above configuration, the used roll towel to be wound up is subjected to sliding resistance by the brake means, so that tension is applied to the used roll towel (the part immediately before being wound up) by the winding operation by the drive roller. It hangs and is tightly wound up.

〔Example〕

Next, one embodiment of the present invention will be described with reference to FIG.

This example (Figure 1 is the above-mentioned draft plan (Figure 4))
This was improved by applying the present invention to the present invention, and the same drawing reference numbers as in FIG. 4 are given to the same or similar constituent parts as in the above-mentioned prototype.

The difference between this embodiment and the above-mentioned draft is that the first
As shown in Figure A, a brake means (so-called breaker) 20 is installed near the point where the loop portion 6 of the roll towel is being wound up as shown by the arrow B, to provide frictional resistance to the movement in the direction of the arrow B. This is what we have set up.

FIG. 1B is a sectional view showing details of the breaker 20.

A friction piece 20a is provided along the winding path arrow B' of the used roll towel and fixed to the main body 1''.

A pressing roller 20b is provided to press the used roll towel toward the friction piece 20a.

Bearing bracket 20c fixed to main body 1″
Therefore, the tilting lever 20 is moved via the lever shaft 20d.
The pressing roller 20b is supported at the tip of the tilting lever 20e.

Although the pressing roller 20b of this example has a structure that presses the used roll towel toward the friction piece 20a by its own weight, a biasing spring (not shown) may be provided to apply a pressing force.

When carrying out the present invention, the brake means is not limited to the one constituted by a friction piece and a pressing roller as in this example. Any structure may be used as long as the movement of the used roll towel in the winding direction is braked by some means (for example, a pair of friction plates).

As a result, tension is applied to the area T between the breaker 20 and the used roll towel 7 shown in FIG. 1A, and the winding operation of the used roll towel 7 is performed firmly and tightly.

[Effects of the Invention] As detailed above, when the roll towel cabinet of the present invention is applied, the advantage of the proposed device that there is no need to move the axial center position of the used roll towel take-up shaft is lost. Used roll towels can be rolled up tightly and tightly without being twisted.
