Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a rolled wet towel manufacturing device having a simple configuration that can always cut a sheet material drawn from a supply source into a constant size.

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 ``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, we developed the Utility Model 63-108730 as a compact wet towel manufacturing device that can make inexpensive and disposable paper towels, non-woven cloth towels, etc. in-house.
The invention related to the above issue, ``A device for manufacturing rolled wet towels,'' has been proposed. In the manufacturing device according to this invention, a sheet roll in which a sheet material for wet towels made of paper or non-woven fabric is wound in a roll shape is rotatably mounted, and the sheet material is sequentially transferred from this sheet roll via a feed roller. It is configured to be pulled out.

A receiver blade is fixedly disposed on the downstream side of the feed roller in the sheet material feeding direction, and extends in the width direction of the sheet material (a direction intersecting the feeding direction) in close proximity to the sheet material feeding path. ing. Further, a rotating shaft including a cutting blade is rotatably disposed parallel to the feed roller at a position facing the receiving blade across the sheet material. Therefore, the sheet material fed between the receiving blade and the rotating shaft by the feeding roller is cut in a direction intersecting the feeding direction under the interlocking action of both blades. Furthermore, the sheet material cut to a predetermined length is
The wet towel is dropped between the endless belt and the friction plate, and is wound up into a roll to produce a "wrapped wet towel" of a predetermined diameter.

Problems that the invention aims to solve If the above-mentioned "wrapped wet towels" provided for customer service are short, they cannot wipe hands sufficiently and cannot fully perform their function as wet towels. Can not. On the other hand, if the towels are long, they can achieve their purpose as wet towels, but on the other hand, they waste material and increase costs even if they are made of cheap and disposable paper or non-woven fabric. .

Therefore, in the above-mentioned manufacturing apparatus, a rotation detecting means is disposed on the feed roller that pulls out the sheet material from the sheet roll, and when this detecting means reaches a predetermined value, the driving of the rotating shaft is started and the cutting The sheet material is cut under the joint action of the blade and the receiving blade. Therefore, by keeping the set value of the detection means constant, it is possible to cut the sheet material to a fixed size. Furthermore, when cutting the sheet material, it is necessary to stop the feeding of the sheet material, so in the above device, a clutch is disposed at the connection part between the drive motor, the feed roller, and the rotating shaft, and the sheet material is cut. While feeding the rotating shaft, the drive of the rotating shaft is stopped. Then, when a sheet material of a predetermined length is fed, the clutch is turned on and off to stop driving the feed roller and start the rotating shaft, thereby cutting the stopped sheet material. It is configured to do so.

However, in this case, the above-mentioned detection means is required, as well as a control means for controlling the on/off of the clutch based on the detection signal of the detection means, which increases the number of parts and increases manufacturing costs. There is a drawback that the amount increases. Furthermore, disadvantages have also been pointed out, such as the connection portions between the feed roller and the rotating shaft drive means being complicated, making them more likely to break down, and making assembly into manufacturing equipment complicated.

Purpose of the invention This invention was proposed in order to suitably solve the above-mentioned problems, and its purpose is to provide a means for a simple configuration that can always cut sheet materials to a constant size. shall be.

Means for Solving the Problems In order to overcome the above-mentioned problems and suitably achieve the intended purpose, the present invention provides a feed roller that feeds the sheet material drawn from a supply source, and a sheet material of the feed roller. A fixed blade disposed on the downstream side in the feeding direction, and a rotary blade attached to a rotating roller disposed opposite to the fixed blade across the sheet material fed by the feed roller, and the fixed blade and the rotary blade In the rolled wet towel manufacturing apparatus, the sheet material is cut in a direction intersecting the feeding direction thereof under the interlocking action of the feed roller. It consists of a gear that is provided and integrally rotates and meshes with the gear, and a presser plate that normally presses the sheet material elastically against the feed roller and separates from the feed roller at the timing of cutting the sheet material. , the rotation roller and the feed roller are synchronously rotated by the drive source via the gear train to feed the sheet material,
The method is characterized in that the holding plate is separated from the feed roller to stop feeding of the sheet material at the timing when the sheet material is cut under the cooperative action of the rotary blade and the fixed blade arranged on the rotary roller. shall be.

Embodiments Next, a preferred embodiment of the rolled wet towel manufacturing apparatus according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a longitudinal sectional view of a rolled wet towel manufacturing apparatus in which the present invention is suitably implemented, and FIG. 2 is a schematic perspective view of main parts showing a sheet material feeding mechanism and cutting mechanism.

(Regarding the roll holder) As shown in the drawings, a pair of side plates 11, 11 are provided upright on both sides in the width direction of a bottom plate 10 formed in a rectangular shape, and a front panel 12 and a rear panel 13 are opposed to each other at both ends in the length direction. These members define a generally rectangular space 14 that is open upward. In this space 14, a roll holder 16 is arranged which freely rotatably stores a sheet roll 15 in which a sheet made of, for example, a non-woven fabric is wound around a paper tube serving as a core. That is, as shown in FIG. 1, a U-shaped stepped portion 16a is formed on opposing side surfaces (only one is shown) of the roll holder 16, and the central core of the sheet roll 5 and the A holder (none of which is shown) fitted to the core is rotatably supported.

Further, at the upper front end of the roll holder 16, a projecting portion 16b is formed which functions to guide the sheet material 15a pulled out from the sheet roll 15 stored in the holder 16 to a feed roller 21, which will be described later. Note that the sheet material 1 pulled out from the sheet roll 15 is placed at a predetermined position on this projecting portion 16b.
Means 65 for detecting the paper breakage of 5a is provided.

The roll holder 16 has a water sprinkler pipe 4 which will be described later.
A water tank 17 for supplying water to the tank 1 is detachably housed in an inverted state. That is, as shown in FIG. 1, a recess 16c into which the water supply part 17a of the water tank 17 is inserted is formed at the bottom of the roll holder 16, and a water supply pipe 16d led out from the recess 16c.
is connected to a suction pipe 18a of a pump 18 installed on the bottom plate 10. Further, the discharge pipe 18b of the pump 18 is connected to the water sprinkling pipe 41 via a supply pipe 19. Note that the water tank 1
7 is configured such that the water in the tank can be discharged only when the water supply part 17a is inserted into the recess 16c in an inverted state. Therefore, the water pumped from the water tank 17 via the pump 18 is sprayed onto the sheet material 15a from each water sprinkling hole 41a formed in the water sprinkling pipe 41, as will be described later.

A coarse mesh filter 20 is interposed in the recess 16c, and is configured to collect large dust and the like generated from the sheet roll 15 and the like so that the dust is not sucked into the pump. A fine mesh filter (not shown) is disposed on the discharge pipe 18b side of the pump 18 to collect fine dust that cannot be collected by the filter 20 and prevent clogging of the water sprinkling pipe 41. The structure is designed to prevent this from occurring. Furthermore, these filters are removably arranged and can be removed and cleaned as appropriate.

(Sheet material feeding mechanism) Overhang portion 16b in the roll holder 16
As shown in FIG. 1, below the side plate 11,
A feed roller 21 is rotatably installed between the rollers 11 and 11. As shown in FIG. 2, a gear 23 is disposed on the shaft 22 of this roller 21 at an end projecting from one side plate 11. As shown in FIG. Further, a motor 24 is disposed within the space 14, and a gear 25 is disposed at the end of its rotating shaft protruding from the side plate 11. The rotary blade mounting roller 35 meshes with the gear 23 via a gear 38 disposed on the shaft 37 of the rotary blade mounting roller 35. Therefore, by driving the motor 24, the feed roller 21 is rotated counterclockwise in FIG. A plurality of O-rings 26 protruding outward in the radial direction are wound around the feed roller 21 at predetermined intervals in the axial direction, and these O-rings 26 function to smoothly pull out the sheet material 15a.

The roll holder 16 holds the feed roller 21 in between.
On the opposite side, as shown in FIG.
A shaft 27 is installed parallel to the feed roller 21 between the rollers 1 and 11, and a dogleg-shaped presser plate 28 is pivotally supported on the shaft 27. That is, the lower bent piece 28a of the presser plate 28 has feed rollers 21 at both ends in the longitudinal direction.
Projecting pieces 28b, 28b projecting in a direction away from
is formed, and the shaft 27 is inserted through both protruding pieces 28b, 28b. In addition, the upper bent piece 2 of the presser plate 28
A torsion spring 29 is disposed on the opposite side of the feed roller 21 with 8c in between, and this torsion spring 29 functions to always press the upper bent piece 28c against the O-ring 26 of the feed roller 21. Therefore, if the sheet material 15a pulled out from the sheet roll 15 is interposed between the O-ring 26 and the presser plate 28, the sheet material 15a will be pressed against the feed roller 21, so that the rotation of the roller 21 will not affect the sheet material 15a. Accordingly, the sheet material 15a is sequentially pulled out from the sheet roll 15 (see FIG. 6a).

Further, a guide 30 is disposed vertically between the feed roller 21 and the presser plate 28 along the roller 21, and this guide 30 guides the sheet material 15a fed by the feed roller 21 vertically downward. It functions as it should. This guide 30 is formed with a notch 30a that opens upward, as shown in FIG. 2, at a position corresponding to the position of the O-ring 26 wound around the feed roller 21. As shown in FIG. 1, the O-ring 26 of the feed roller 21 is configured to protrude from the notch 30a of the guide 30 toward the presser plate 28. That is, the guide 30
allows the sheet material 15a to be fed by the O-ring 26 of the feed roller 21, and also allows the sheet material 15a to be fed by the O-ring 26 of the feed roller 21.
It functions to prevent the leading end in the feeding direction of a from being caught in the feeding roller 21.

(Sheet Material Cutting Mechanism) Below the feed roller 21, on the right side of the sheet material 15a that is fed in a hanging manner from the roller 21, a fixed blade bracket 31 formed in an inverted “dog” shape is attached to the both sides of the feed roller 21. It is rotatably supported on a shaft 32 installed between the plates 11,11. That is, the lower bent piece 31a of the fixed blade bracket 31 has the following:
Protrusions 31b, 31b (only one is shown) that protrude toward the back side (in the direction away from the sheet material 15a that is fed hanging from the feed roller 21) are formed at both ends in the longitudinal direction, and the shaft 32 has both protrusions 31b, 31b. is inserted into. A fixed blade 33 oriented toward the front panel 12 is disposed along the longitudinal direction on the upper bent piece 31c of the fixed blade bracket 31.
This fixed blade 33 is set to have a longer length than the width of the sheet material 15a. Further, a torsion spring 34 is interposed in the shaft 32 on which the fixed blade bracket 31 is pivotally supported, and the bracket 31 and the fixed blade 33 are always elastically biased in the direction of the rotary blade 36, which will be described later. There is.

Below the presser plate 28 is a rotary blade mounting roller 35 that faces the fixed blade bracket 31 across the sheet material 15a hanging down from the feed roller 21 and extends parallel to the fixed blade bracket 31.
is rotatably installed between the side plates 11, 11. A rotating blade 36 extending along the axial direction of the roller 35 is disposed on the roller 35 with its cutting edge protruding outward in the radial direction. Note that the rotary blade 36 is arranged at a slight angle to the axis of the roller, and the rotary blade 36 is arranged at a slight angle with respect to the axis of the roller.
When the rotary blade attachment roller 35 is rotated when cutting the blade 5a, the rotary blade 36 and the fixed blade 33 come into contact with each other sequentially from one longitudinal end to the other end.

Further, the shaft 37 of the rotary blade mounting roller 35 has a gear at an end protruding from one side plate 11 (the same end at which the gear 23 disposed on the shaft 22 of the feed roller 21 is disposed). 38 are arranged. This gear 38 is connected to the motor 2 as shown in FIG.
The rotary blade mounting roller 35 is rotated clockwise in FIG. 1 by driving the motor 24. Rotate to . That is, the rotary blade mounting roller 35 on which the rotary blade 36 is disposed and the feed roller 21 are connected to the gear train 2.
5, 38, and 23, the sheet material 15 pulled out from the sheet roll 15 is always cut to a constant size. Note that by changing the ratio of the number of teeth of each gear 25, 38, 23, it is possible to change the cutting dimension of the sheet material 15a.

The side plate 1 of the rotary blade mounting roller 35
A cam 3 that rotates integrally with the roller 35 is attached to the inner shaft end of the roller 35 (on the opposite side to the end where the gear 38 is disposed).
9 are arranged. On the outer periphery of this cam 39,
As shown in FIG. 3, a protrusion 39a is formed that protrudes outward in the radial direction, and this protrusion 39a is set to abut the lower end of the lower bent piece 28a of the holding plate 28. Further, the protrusion 39a is configured to abut against the lower bent piece 28a of the presser plate 28 while the rotary blade 36 is rotating and in contact with the fixed blade 33 (while cutting the sheet material 15a). ,
The formation range is set. Therefore, the rotary blade mounting roller 35 rotates, and the protrusion 39a of the cam 39
When the presser plate 28 comes into contact with the presser plate 28, the presser plate 28 rotates counterclockwise around the shaft 27, and the upper bent piece 28c separates from the O-ring 26, as shown in FIG. 6c. 15a is no longer pressed by the feed roller 21. Then, at this timing, the rotary blade 36 and the fixed blade 33 come into contact with each other, and the sheet material 15a is cut in a direction intersecting the feeding direction.

That is, the upper bent piece 28c of the presser plate 28
As a result, the feed roller 2 is separated from the O-ring 26.
Even if the roller 1 rotates, the sheet material 15a is
Simply slipping on the top will no longer give active feed. As a result, the rotating blade 36 and the fixed blade 33
When the sheet material 15a is cut under the interlocking action, the sheet material 15a does not move and the cut surface is not distorted, and a neat cut surface can be obtained. Further, since there is no need to stop the drive of the feed roller 21, there is no need to provide a disconnecting means such as a clutch, and the structure is simplified.

In addition, on the side of the end of the rotary blade mounting roller 35 opposite to the end where the cam 39 is disposed, as shown in FIG.
A roller 66 having a diameter larger than that of the roller 35 is provided. In addition, protrusions 67, 67 are formed on both axial ends of the fixed blade 33 so as to protrude from the blade of the fixed blade 33 toward the rotary blade mounting roller 35.
The protrusion 67 facing the roller 66 is configured to always abut against the roller 66 under the elastic action of the torsion spring 34.
Except when the rotary blade mounting roller 35 and the fixed blade 33 are in cooperation with each other, a gap is defined between the rotary blade mounting roller 35 and the blade portion of the fixed blade 33 to allow the sheet material 15 a to pass through.

Furthermore, the other protrusion 67 faces a position facing the end of the rotary blade 36 located inside the cam 39 disposed on the rotary blade mounting roller 35,
The protrusion 67 connects the rotating rotary blade 36 to the fixed blade 33.
It functions to reliably guide the blade to the blade. Note that the rotary blade 36 is connected to the rotary blade mounting roller 3 as described above.
The fixed blades 3 are arranged at a predetermined angle with respect to the axis of the fixed blade 3, and the fixed blades 3
It is set so that it comes into contact with 3. That is,
The rotary blade 36 , which rotates integrally with the rotary blade mounting roller 35 , first comes into contact with the protrusion 67 of the fixed blade 33 at one longitudinal end thereof, and is guided by the protrusion 67 to rotate the fixed blade 33 to release the torsion spring 34 . It reaches the blade part of the fixed blade 33 while swinging against the elastic force. Therefore, the rotary blade 36
The blade portion of the fixed blade 33 is in reliable contact with the blade portion of the fixed blade 33, and is always pressed under a constant pressure by the elasticity of the torsion spring 32, so that the sheet material 15a can be cut smoothly.

Note that when the fixed blade 33 is fixed to the manufacturing equipment 9, it is necessary to set the position of the blade part of the fixed blade 33 with extremely high precision with respect to the movement locus of the blade part of the rotary blade 36. If the positioning is not accurate, the sheet material 15a may not be cut or the double blades 36 and 33 may collide, causing damage to the blade portion. However, in this cutting mechanism, the fixed blade 33 is configured to swing around the shaft 32 and to smoothly guide the rotary blade 36 to the blade portion of the fixed blade 33 by the protrusion 67. There is no need to position the fixed blade 33 with high precision, and there is an advantage that the assembly work can be easily performed.

(Regarding the water tray and the sprinkler pipe) Below the fixed blade bracket 31, there is a water tray 40 that guides the sheet material 15a to the rolled wet towel manufacturing section 43, which will be described later, and receives water sprinkled from the sprinkler pipe 41. It is arranged so as to have a downward slope approaching the front panel 12 as it goes downward. This water tray 40 is removably mounted on the positioning member 62 of the rolled wet towel manufacturing section 43, and is configured so that it can be easily removed from the manufacturing device 9 for cleaning and maintenance (see Fig. 4). . Further, the upper end of the water tray 40 is connected to a fixed blade bracket 31 as shown in FIG.
The back side of the lower bent piece 28a (sheet material 1
5a), and reliably prevents the sheet material 15a fed from above from entering the back side of the water tray 40.
It is configured to guide the sheet material 15a to the front side of the water tray 40.

As shown in FIGS. 1 and 4, this water tray 40 includes a vertical back plate 40a and a plurality of ribs 40b arranged at appropriate intervals in the longitudinal direction of the back plate 40a.
The lower end of each rib 40b bulges toward the front panel, and the front side of each rib 40b is connected by a dam 40c. Also, a hole 4 is provided between the dam material 40c and the back plate 40a.
0d is defined, and this hole 40d functions to cause a part of the water sprinkled from the water sprinkling pipe 41 to drip onto the sheet material 15a being transferred through the rolled wet towel manufacturing section 43.

As shown in FIG. 3, the water sprinkling pipe 41 is removably installed between both side plates 11, 11 on the front side of the water tray 40. This watering pipe 41 has a plurality of watering holes 41a oriented toward the water tray 40,
Water pumped from the water tank 17 via the pump 18 is sprayed toward the back plate 40a of the water tray 40 through the water sprinkling hole 41a. As a result, the sheet material 15a hanging down from the feed roller 21 and located in front of the back plate 40a of the water tray 40 is provided with moisture necessary as a wet towel (see FIG. 6b). Further, the water that has not been absorbed by the sheet material 15a is removed from the hole 40d formed at the lower end of the water tray 40.
From there, a rolled wet towel manufacturing section 43 (to be described later) drips drops onto the transported sheet material 15a to compensate for the lack of moisture in the water tray.

The discharge pipe 18b of the pump 18 and the water sprinkling pipe 4
A pump 18 is connected to the supply pipe 19 that communicates with the pump 18.
Slot valve 4 that adjusts the pressure of water pumped from
2 is interposed. Further, a check valve 90 is interposed in the supply pipe 19 to prevent all water remaining in the water sprinkling pipe 41 and the supply pipe 19 from flowing back into the pump 18 when water sprinkling is finished.
That is, if no water remains in the water sprinkling pipe 41 and the supply pipe 19, it will take time for the water pumped by the pump 18 to reach the water sprinkling pipe 41 during the next watering, resulting in a lag in the watering timing. Therefore, the sprinkler pipe 41 and the supply pipe 19 are always
By leaving water inside, it is possible to effectively prevent the timing of watering from being skewed.

(Regarding the rolled wet towel manufacturing department) A pair of guide rails 54, 54 that slope downward as they are separated from the front panel 12 are opposed to the lower side plates 11, 11 that are spaced a predetermined distance from the cutting mechanism of the sheet material 15a.

Effects of the Example Next, the effects of the rolled wet towel manufacturing apparatus and the manufacturing process of the "wrapped wet towel" according to the example will be explained.

First, as shown in FIG. 6a, the sheet material 1 is removed from the sheet roll 15 stored in the roll holder 16.
The tip 5a is pulled out and inserted between the feed roller 21 and the presser plate 28. Note that at this time, the rotary blade 36 is in a state immediately after being separated from the fixed blade 33. Further, a water tank 17 filled with water is stored in the roll holder 16 in an inverted state.

When the start button is pressed in this state, the motor 24 is driven and the rotary blade mounting roller 35 and the feed roller 21 are rotated in opposite directions via the gears 25, 38, and 23. Thereby, the sheet roll 1 rotatably stored in the roll holder 16
The sheet material 15a is pulled out from the sheet material 1
5a is fed vertically downward along a guide 30 disposed close to the feed roller 21.

Then, the sheet material 15a is fed downward by a predetermined length, and the tip of the sheet material 15a passes through the gap defined between the fixed blade 33 and the rotary blade mounting roller 35, and passes through the front surface of the water tray 40. When the water drops down to a certain point, the pump 18 is energized at the required timing. As a result, as shown in FIG. 6b, water that is force-fed from the water tank 17 to the water sprinkling pipe 41 via the pump 18 is sprayed onto the sheet material 15a through each water sprinkling hole 41a.

When the rotary blade mounting roller 35 rotates to a predetermined angle, the cam 3 disposed at the shaft end of the roller 35 rotates to a predetermined angle.
The protrusion 39a of 9 comes into contact with the presser plate 28, and the upper bent piece 28c of the presser plate 28 is separated from the feed roller 21 (see FIG. 6c). As a result, active feeding is no longer applied to the sheet material 15a.
When the rotary blade mounting roller 35 further rotates, the vicinity of one end in the axial direction of the rotary blade 36 is exposed to the protrusion 6 of the fixed blade 33.
7, and while slidingly contacting the protrusion 67, the fixed blade 33
is guided by the blade. Further, since the fixed blade 33 is configured to be able to swing around the shaft 32, the rotary blade 36 contacts the fixed blade 33 and swings it, thereby cutting the sheet material 15a. When the rotary blade 36 separates from the fixed blade 33, the fixed blade 33, which had been pressed by the rotary blade 36, returns to the initial position where the protrusion 67 contacts the large diameter roller 66, and waits for the next cutting. Note that the pump 18 is stopped at an appropriate timing and the water pipe 4 is
Watering from 1 is stopped.

In this way, by providing the rotary blade 36 on the rotary blade attachment roller 35 that rotates integrally with the gear 38 that meshes with the gear 25 that is rotationally driven by the motor 24, the sheet material 15a is It is cut every time it rotates. Further, since the feed roller 21 rotates integrally with the gear 23 that meshes with the gear 38, the rotation ratio between the rotary blade mounting roller 35 and the feed roller 21 is always constant. Therefore,
The length of the sheet material 15a pulled out from the sheet roll 15 by the feed roller 21 during one rotation of the rotary blade attachment roller 35 is constant, and thereby the sheet material 15a can be cut to a fixed size. Furthermore, when the rotary blade 36 and the fixed blade 33 are connected, the cam 39 that rotates integrally with the rotary blade mounting roller 35 separates the presser plate 28 that presses the sheet material 15a against the feed roller 21 from the feed roller 21. Then, feeding of the sheet material 15a can be stopped.

Further, by configuring the fixed blade 33 to be swingable and providing the fixed blade with a protrusion 67 that guides the rotary blade 36, the rotary blade 36 is smoothly guided to the blade part of the fixed blade 33. Since the rotary blade 36 and the fixed blade 33 are pressed against each other with a constant pressure (the elasticity of the torsion spring 34), reliable cutting of the sheet material 15a can be achieved.

When the sheet material 15a having a predetermined length is cut,
The upper part of the sheet material 15a falls down in the direction away from the water tray 40 and comes into contact with the endless belt 47 of the rolled wet towel manufacturing section 43. At this time, since the upper part of the sheet material 15a falls down while contacting the water sprinkling pipe 41, each water sprinkling hole 41 of the water sprinkling pipe 41
You can wipe the water droplets attached to a (6th
(see figure c).

The motor 55 disposed within the manufacturing device 9
is driven at the same time that the manufacturing apparatus 9 starts operating, so the drive roller 46 rotates clockwise via the gear 56 of the motor 55 and the gear 57 that meshes with the gear 56, causing the endless belt 47 to run. ing. Therefore, the sheet material 15a that has fallen onto the endless belt 47 is transported by the endless belt 47. At this time, the lower end of the sheet material 15a is located at the lower bulge of the rib 40b in the water tray 40, so this lower end is bent and the sheet material 1
At the leading end of 5a in the running direction, the sheets are in a double overlapping state. Then, in this state, the sheet material 15a
When the tip of the sheet material 15a is transferred to the position where the first fixed roller 48 and the second fixed roller 49 are arranged, the endless belt 47 passing between the two rollers 48 and 49 is tilted, so that the sheet material 15a As shown in FIG. 6d, the tip of the fixing belt 51
It abuts against the inclined portion 51a.

Since the endless belt 47 is running continuously, the leading end of the sheet material 15a that comes into contact with the fixed belt 51 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 15a that has come into contact with the fixed belt 51 is folded back in the opposite direction to the transport direction and then continues to be fed without being rolled inward, the end will move in the opposite direction to the transport direction. This prevents the roll from being formed. However, as mentioned above,
Fixed belt 51 that the tip of the sheet material 15a comes into contact with
Since the third fixed roller 50 is disposed upstream of the sheet material 15a, even if the sheet material 15a moves in the opposite direction to the conveying direction, the end portion comes into contact with the third fixed roller 50 and is rolled inward. The starting end of the roll can be reliably formed.

Sheet material 1 on which the starting end of the roll is formed
5a is rolled while being transferred between the fixed belt 51 and the endless belt 47 and wound to a predetermined diameter. This rolled sheet material 15a is attached to the guide rails 54, 5 as shown in FIG. 6d.
The liquid drops from the opening 12b of the front panel 12 to the lid 58 which also serves as a saucer via the guide plate 64 installed at the top 4. Therefore, as shown in FIG. 5, by opening the lid 58, the "wrapped wet towel" can be taken out.

Effects of the Invention As explained above, according to the rolled wet towel manufacturing apparatus according to the present invention, the feed roller and the rotary roller equipped with a rotary blade are connected by a gear train, so that while the rotary roller makes one revolution, the feed roller The length of the sheet material fed is constant, and the length of the sheet material cut under the cooperative action of the rotary blade and the fixed blade is always constant. Moreover, the feeding of the sheet material 15a can be temporarily stopped by simply separating the presser plate that presses the sheet material against the feed roller at the timing when the sheet material is cut by the rotary blade and the fixed blade. Therefore, there is no need to provide a clutch or the like to the feed roller or rotating roller, and sheet material can be cut to size with an extremely simple configuration, reducing manufacturing costs and simplifying assembly work. It is possible to achieve the following effects.
