[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 "wrapped wet towels" per day, most of the towels are currently supplied by wet towel manufacturers. However, while ``rolled 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, Fig. 6 shows an outline of the rolled wet towel manufacturing device and the manufacturing department according to the above proposal. Refer to and explain.

FIG. 6 is a longitudinal sectional side view of a rolled wet towel manufacturing device, and 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 pump 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 presser 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.

A protruding piece 78 shown in FIG. 4 having a ∧-shaped gap is provided protrudingly on the back side of the upper transfer portion of the endless belt 46, and a ∧-shaped protruding piece 78 is provided in the gap of this fourth protruding piece 78 as shown in FIG. The end portions of the second regulating plate 70 thus formed are removably fitted. At this time, the corner of the second regulating plate 70 is positioned so as to come into contact with the back surface of the upper transfer section of the endless belt 46 and push the transfer section upward by a predetermined height. That is,
As shown in FIG. 3, the endless belt 46 facing between the first regulating plate 68 and the second regulating plate 70 is sloped upward toward the downstream side in the running direction. Further, the sheet material 14a that is transported along the inclined portion
The tip of the fixing belt 58 is set to point toward the inclined portion 58a of the fixing belt 58.

Effects of the Example Next, the effects of the rolled wet towel manufacturing section according to the example will be described below. The sheet material 14a, which has been cut into a predetermined length using a cutting mechanism and has been given the required moisture, is sent to the rolled wet towel manufacturing unit 36.
When the sheet material 14a is supplied to the leading end side (the side where the driven roller 42 is disposed), the sheet material 14a is transported in a predetermined direction by the endless belt 46. The tip of the sheet material 14a is connected to the first regulating plate 68 and the second regulating plate 7.
When the sheet material 1 is transported to the arrangement position 0, as shown in FIG.
The tip of 4a is connected to the inclined portion 58 of the fixed belt 58.
It comes into contact with a. Note that since the inclined portion 68a of the first regulating plate 68 extends over the entire area from the surface of the endless belt 46 to the back surface of the fixed belt 58, there is no possibility that the sheet material 14a will cause a paper jam. .

Since the endless belt 46 is running continuously, the leading end of the sheet material 14a that comes into contact with the fixed belt 58 is folded back in the opposite direction to the transport direction and then wound inward to form the starting end of the roll. .
At this time, if the leading end of the sheet material 14a that is in contact with the fixed belt 58 is folded back in the opposite direction to the transport direction and continues to be fed without being rolled inward, the end will move in the opposite direction to the transport direction. Otherwise, the roll will not be formed. However, as mentioned above,
Fixed belt 58 that the tip of the sheet material 14a comes into contact with
Since the inclined portion 68a of the first regulating plate 68 is located at an inclined position on the upstream side of The starting end of a roll can be formed. Moreover, since the open end of the inclined portion 68a is in contact with the fixed belt 58, the sheet material 14a is prevented from jamming, and smooth conveyance is achieved.

Sheet material 1 on which the starting end of the roll is formed
4a is transferred and rolled between the fixed belt 58 and the endless belt 46, wound to a predetermined diameter, and then released from the manufacturing unit 36.

Effects of the Invention As explained above, according to the rolled wet towel manufacturing department according to the present invention, two regulating plates are arranged across the upper transfer part of the endless belt, and a fixed belt is attached to the endless belt passing between the two regulating plates. It is configured to provide a directional inclination. Therefore, the starting end of the roll can be reliably formed at the leading end of the sheet material transported by the endless belt. Furthermore, since no gap is defined between the first regulating plate and the fixing belt, there is no fear that the sheet material will jam, and smooth transport of the sheet material can be achieved.
Further, since the number of parts can be reduced, manufacturing costs can be reduced, and there are also advantages that assembly can be simplified.
