Description

[Detailed description of the invention] Industrial application field This invention is equipped with an endless belt and a fixed belt, and a sheet material of a predetermined length is sandwiched between both belts and rolled while being conveyed. This relates to improvements to the wet towel manufacturing department that provides the following benefits.

BACKGROUND OF THE INVENTION Coffee shops, restaurants, and other eating and drinking establishments provide "wrapped towels" as a customer service. Because this type of facility uses a large amount of "rolled towels" per day, most of the towels are currently supplied by towel manufacturers. However, while ``wrapped wet towels'' made of towel cloth can be used repeatedly, they not only have the problem of being extremely unsanitary if the recycling process is incomplete, but also have the drawback of increasing costs.

Therefore, the applicant of this case has been working diligently to develop a compact rolling towel manufacturing device that can make inexpensive and disposable "wrapped towels" made of paper or non-woven fabric at home, and has filed multiple utility model registration applications. Summer. The rolled wet towel manufacturing apparatus according to these applications can fully automatically and efficiently manufacture a "wrapped wet towel" in which a sheet material made of paper or nonwoven fabric is wound into a roll. This idea is
Since this relates to the rolled wet towel manufacturing section installed in this rolled wet towel manufacturing device, in order to contribute to a basic understanding, first of all, the outline of the rolled wet towel manufacturing device and manufacturing section according to the above proposal is shown in Figures 5 and 5. This will be explained with reference to FIG.

FIG. 5 is a longitudinal sectional side view of a rolled wet towel manufacturing device, in which a storage section 12 that opens upward is formed inside the device main body 10 formed in a rectangular shape. A sheet roll 14 in which a sheet material 14a is wound around a paper tube serving as a core is housed so as to be freely rotatable. Further, a water tank 18 for supplying water to a watering pipe 16 to be described later is detachably housed in the storage portion 12.
The water is pumped to the sprinkler pipe 16 via a pump 20 disposed inside the device.

A feed roller 22 is rotatably installed on the left side of the storage section 12, and the roller 22 is configured to rotate counterclockwise by an appropriate driving means. The feed roller 22 also includes a plurality of O-rings 24 (only one is shown) that protrude outward in the radial direction.
The O-rings 24 function to prevent the sheet material 14a from slipping on the rollers. Note that on the opposite side of the storage section 12 with the feed roller 22 in between,
A press plate 28 is rotatably supported, and is pressed against the O-ring 24 of the feed roller 22 by a torsion spring 26. Therefore, if the feed roller 22 is rotated counterclockwise while the sheet material 14a pulled out from the sheet roll 14 is sandwiched between the presser plate 28 and the O-ring 24, the sheet material 14a will be pulled out one after another. Supplied.

Below the feed roller 22, a rotary blade 30 and a fixed blade 32 are arranged parallel to the width direction of the sheet material 14a, sandwiching the sheet material 14a that is fed hanging down from the roller. Also, the rotary blade 30
is disposed on a rotary blade mounting roller 34 which is rotatably supported on the main body 10 of the apparatus, and this roller 34 is configured to be rotationally driven synchronously by the driving means of the feed roller 22. Therefore, the sheet material 14a passing between the fixed blade 32 and the rotary blade mounting roller 34 rotates the rotary blade mounting roller 34 in a predetermined direction, thereby achieving a linking action between the rotary blade 30 and the fixed blade 32. Cut widthwise at the bottom.

At a predetermined distance below the cutting mechanism consisting of the rotary blade 30 and the fixed blade 32, as shown in FIG.
The sheet material 14a, which is cut into a predetermined length by the cutting mechanism, is rolled into a roll having a predetermined diameter in the manufacturing section 36. In addition, the manufacturing department 36
In this step, the sheet material 14a hanging down from the cutting mechanism is guided to the manufacturing section 36, and the water sprinkling pipe 16 is
A water tray 38 is provided which functions to receive water from the tank. A water sprinkling pipe 16 having a plurality of water sprinkling holes (not shown) directed toward the water pan 38 is disposed on the front side of the water pan 38 , and water pumped from the water tank 18 via the pump 20 is fed through the water pipe 16 . , is sprayed onto the sheet material 14a located in front of the water tray 38 from the water sprinkling holes. As a result, the sheet material 14a is provided with moisture necessary for use as a wet towel.

As shown in FIG. 6, the rolled wet towel manufacturing unit 36 rotates a driven roller 42 and a driving roller 44 at both ends in the longitudinal direction of a pair of support frames 40, 40 which are disposed facing each other with a predetermined distance apart. An endless belt 46 is freely wound between the rollers 42 and 44. Further, a gear 48 is coaxially disposed at one end of the drive roller 44 in the axial direction inside the support frame 40, and this gear 48 is a gear disposed on the rotating shaft of a motor 50 disposed within the main body of the apparatus. 5
It is configured to mesh with 2. Therefore, by driving the motor 50, the endless belt 4
6 runs in a predetermined direction.

The rear half from the approximate middle position of both the support frames 40, 40 (in the flow direction of the endless belt 46)
As shown in FIG. 5, a fixed belt 54 is disposed to surround the drive roller 44 at a predetermined distance from the conveying surface of the endless belt 46. That is, when the sheet material 14a that has been cut into a predetermined length and has been moistened is supplied to the manufacturing section 36, the sheet material 14a is rolled while being held between both belts 46 and 54 and rolled into a roll shape. Get caught up in it. This "wrapped wet towel" is then discharged into a lid 56 which also serves as a saucer and which is disposed on the front of the main body 10 so as to be openable and closable.

Problems to be Solved by the Invention In the rolled wet towel manufacturing section 36, a gear 48 is provided at one axial end of the drive roller 44 facing inside the support frame 40, and power is transmitted through the gear 48. There is. Therefore, the center C ₁ of the axial length of the drive roller 44 is
As shown in FIG. 6, both the support frames 40, 4
0 (ie, the width direction center C of the manufacturing section 36). On the contrary,
The center C ₂ of the axial length of the driven roller 42 is
It coincides with the center C of the manufacturing department 36.

Here, in the so-called belt conveyor as described above, in order to prevent the endless belt from moving in the width direction while running, and to automatically align the widthwise center of the endless belt with the axial center of the roller, the roller is The outer periphery of both ends in the axial direction is tapered to slightly converge toward the shaft end.

However, in the rolled wet towel manufacturing section 36, the center C ₁ of the driving roller 44 and the center C 1 of the driven roller 42 are
Since C ₂ is offset, both rollers 44 and 42
If tapers are provided in each of the belts, it is expected that the endless belt 46 will be inclined in the running direction. Therefore, at present, only the drive roller 44 that is likely to come into contact with the gear 48 when the endless belt 46 moves is provided with a taper. There is a drawback that it is not possible to expect a proper centering effect. Further, since the drive roller 44 and the driven roller 42 have different shapes, they are not interchangeable at all, which is a factor that increases manufacturing costs.

Furthermore, since the axial center C ₁ of the drive roller 44 and the widthwise center C of the manufacturing section 36 are offset as described above, the endless belt 46 may run at a position offset from the center of the manufacturing section 36 . become. In this case, the sheet material 14a is fed with its widthwise center aligned with the widthwise center of the manufacturing device (the widthwise center of the manufacturing device and the widthwise center C of the manufacturing section 36 coincide). being sent. As a result, the center of the sheet material 14a supplied to the rolled wet towel manufacturing section 36 and the center of the endless belt 46 become misaligned, which is undesirable for smooth transfer.

Purpose of the invention This invention was proposed in order to suitably solve the above-mentioned problems, and provides a means for reliably achieving self-alignment of an endless belt and reducing manufacturing costs. The purpose is to
