Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention This invention can feed a sheet material drawn from a supply source in a normal state, and can smoothly guide the sheet material to a cutting mechanism and a rolled wet towel manufacturing section. The present invention relates to a rolled hand towel manufacturing device.

2. Description of the Related Art At coffee shops, restaurants, and other eating and drinking establishments, a towel cloth "rolled towel" is provided as a customer service. Since facilities of this type use a large amount of "rolled hand towels" per day, most of them use the ones delivered by the hand towel manufacturers.
However, the "rolled towel" of the towel cloth can be repeatedly used, but on the other hand, if the regeneration treatment is not complete, there is a problem that it becomes extremely unsanitary and there is a drawback that the cost increases.

Therefore, as a manufacturing apparatus for compact wet towels that can be manufactured homemade from inexpensive and disposable paper towels and non-woven towels, a device "rolling towel manufacturing apparatus" according to No. Shokai 63-108730 has been proposed. ing. In the manufacturing apparatus according to the present invention, for example, a sheet roll obtained by winding a sheet material for towels made of paper or non-woven fabric into a roll is rotatably mounted. The sheet material pulled out from the sheet roll is sandwiched between a feed roller and a road plate arranged on the downstream side in the feeding direction, and the feed roller is rotationally driven to feed the sheet material on the downstream side. is there.

Further, on the downstream side of the feed roller, a receiving blade fixed to the side plate and a cutting blade arranged on a rotary shaft that rotates in parallel with the feed roller are arranged to face each other across the sheet material feeding path. Further, a nozzle is provided so as to face a portion of the road plate disposed downstream of the receiving blade that is bent downward, and a sheet material that hangs down from the nozzle passing between the receiving blade and the cutting blade is provided. The required amount of water is jetted and supplied. Then, when the sheet material passes a predetermined length between the receiving blade and the cutting blade, the sheet material is cut while the two blades are connected to each other.

Below the cutter and the nozzle composed of the receiving blade and the cutting blade, a rolled hand towel manufacturing section composed of an endless belt and a friction plate is provided, and the necessary wetness as a hand towel is given and a predetermined size. The cut sheet material is dropped and supplied to the rolled hand towel manufacturing section and wound into a roll to manufacture a "rolled hand towel" having a predetermined diameter.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the manufacturing apparatus having the above-described configuration, the sheet material is fed while being sandwiched between the cylindrical feed roller and the road plate, and is cut by the cutter disposed on the downstream side. Has been done. In this case, if the contact pressure of the feed roller with respect to the sheet material is not uniform in the longitudinal direction of the roller, the sheet material fed by the feed roller is fed to the cutter in an inclined state. As a result, the cut surface of the sheet material cut by the cutter does not become straight in the direction intersecting the feeding direction of the sheet material, and the appearance of the completed "rolled hand towel" is poor. Therefore, in order to make the contact pressure of the feed roller on the sheet material uniform, it is necessary to increase the processing accuracy of the roller, which causes a problem of increased cost.

Further, the sheet material fed between the receiving blade and the cutting blade is guided by the road plates arranged on the upstream side and the downstream side with the receiving blade interposed therebetween. Here, since the sheet material is wound in a roll shape, it has a winding curl, which becomes stronger as the sheet roll is consumed and the winding diameter becomes smaller. For this reason, when a gap is defined between the receiving blade and the road plate, the sheet roll is smoothly guided when it has a large diameter, but when the diameter of the sheet roll becomes small, the sheet material is wound due to curling. The tip of the sheet material gets into the gap. Therefore, there is a problem that the sheet material is not fed between the receiving blade and the cutting blade, or enters the back side of the road plate through the gap when passing through the receiving blade, and is not fed to the rolled hand towel manufacturing section. there were.

Therefore, it is necessary to improve the processing accuracy of each member so that a gap is not defined between the road plate and the receiving blade, and there is a drawback that the cost increases. Further, when assembling the receiving blade and the road plate into the manufacturing apparatus, the assembling work must be performed carefully, which is time-consuming and complicated.

DISCLOSURE OF THE INVENTION In view of the above-mentioned problems, the present invention has been proposed in order to suitably solve this problem, and it is possible to feed a sheet material drawn from a supply source in a normal state and smoothly guide the sheet material. The purpose is to provide means.

Means for Solving the Problems In order to overcome the aforementioned problems and preferably achieve the intended purpose, the present invention provides a fixed blade arranged so as to extend in a direction intersecting the sheet material feeding direction, The fixed blade and the rotary blade are composed of a rotary blade attached to a rotary roller arranged opposite to the fixed blade with a sheet material drawn from a supply source interposed therebetween, and a rolled hand towel manufacturing section disposed below the fixed blade and the rotary roller. A sheet material cut into a predetermined length under the action of linking with, in a rolled hand towel manufacturing apparatus configured to be rolled into a roll in the rolled towel hand towel manufacturing section, in the extending direction of the fixed blade above the fixed blade and the rotating roller. And a feed roller formed by winding a plurality of annular members protruding outward in the radial direction at predetermined intervals, and allowing passage of the annular members at a position corresponding to the winding position of the annular members. A notch is formed , A guide disposed in the vicinity of the feed roller in a state where the annular member is projected outward from the notch, and the fixed blade and the rolled hand towel manufacturing section, and the upper end of the sheet material of the fixed blade is fed. It is characterized in that it is composed of a water tray facing the opposite side and the side facing the feeding path.

Embodiments Next, a rolled hand towel manufacturing apparatus according to the present invention will be described below with reference to the accompanying drawings with reference to preferred embodiments. FIG. 1 is a vertical cross-sectional view of a rolled hand towel manufacturing apparatus according to a preferred embodiment of the present invention, and FIG. 2 is a schematic perspective view of an essential part showing an internal structure of the manufacturing apparatus shown in FIG.

(Regarding Roll Holder) As shown in the drawing, a pair of side plates 11 and 11 are erected on both sides in a lateral direction of a bottom plate 10 formed in a rectangular shape, and a front panel 12 and a rear panel 13 face each other at both ends in a longitudinal direction. And a substantially rectangular space 14 that opens upward is defined by these members. In this space 14,
For example, a roll holder 16 that accommodates a sheet roll 15 in which a sheet made of a non-woven fabric is wound around a paper tube serving as a core in a freely rotatable manner is arranged. That is, as shown in FIG. 1, U-shaped step portions 16a are formed on opposite side surfaces of the roll holder 16 (only one is shown). A holder (not shown) fitted to the center core is rotatably supported.

In addition, the roll holder 16 is provided at the upper front end with the holder 16
Sheet material 15 pulled out from the sheet roll 15 stored in
An overhanging portion 16b is formed which functions to guide a to the feed roller 21 described later. In addition, at a predetermined position of the projecting portion 16b, a means 65 for detecting a paper break of the sheet material 15a pulled out from the sheet roll 15 is provided.

In the roll holder 16, a water tank 17 for supplying water to a sprinkling pipe 41 described later is detachably stored in an inverted state. That is, as shown in FIG. 1, a recess 16c into which the water supply unit 17a of the water tank 17 is fitted is formed in the bottom of the roll holder 16, and the water supply pipe 16d led out from this recess 16c is installed on the bottom plate 10. The pump 18 is communicated with the suction pipe 18a. Further, the discharge pipe 18 b of the pump 18 is connected to the water sprinkling pipe 41 via the supply pipe 19. The water tank 17 is configured so that the water in the tank can be drained only when the water supply unit 17a is fitted into the recess 16c in an inverted state. Therefore, the water pumped from the water tank 17 through the pump 18 is, as will be described later, the water spray holes 41a formed in the water spray pipe 41.
The sheet material 15a is sprinkled and supplied.

A filter 20 having a coarse mesh is provided in the recess 16c.
Is installed to collect large dust and the like generated from the sheet roll 15 and the like, and prevent the dust from being sucked into the pump. A fine mesh filter (not shown) is arranged on the discharge pipe 18b side of the pump 18, and collects fine dust that cannot be collected by the filter 20, and the sprinkling pipe 41 is not clogged. It is configured so that it can be prevented from occurring. Further, these filters are detachably arranged so that they can be properly removed and cleaned.

(Sheet Material Feeding Mechanism) Below the overhanging portion 16b of the roll holder 16, as shown in FIG. 1, a feed roller 21 is rotatably installed between the side plates 11 and 11. This roller 21
A gear 23 is arranged at the end of the shaft 22 protruding from the one side plate 11. Further, a motor 24 is arranged in the space 14, and a gear 25 is arranged at an end portion of the rotation shaft thereof which projects from the side plate 11. The gear 25 is mounted on a rotary blade as will be described later, as shown in FIG. It meshes with the gear 23 via a gear 38 arranged on the shaft 37 of the roller 35. Therefore, by driving the motor 24, the feed roller 2
1 rotates counterclockwise in FIG.

As shown in FIG. 2, a plurality of O-rings 26 projecting outward in the radial direction are wound around the feed roller 21 at predetermined intervals in the axial direction. The sheet material 15a is sandwiched between the O-ring 26 and a pressing plate 28 described later, and the sheet material 15a is smoothly fed as the feed roller 21 rotates. Here, the entire feed roller is the sheet material 1
The feeding force applied to the sheet material 15a can be increased by pressing the plurality of O-rings 26 spaced in the longitudinal direction and feeding the sheet material 26 rather than pressing the sheet 5a to feed the sheet material 15a. Moreover, since the contact area between the O-ring 26 and the sheet material 15a is small, the sheet material 1 may be affected by the difference in pressing force.
It is possible to always feed the sheet material 15a to the cutting mechanism described later in a normal state without the 5a being fed obliquely. Further, since the feed roller 21 and the O-ring 26 do not require high-precision processing as in the conventional case, there is an advantage that the manufacturing cost can be reduced.

As shown in FIG. 1, on the side opposite to the roll holder 16 with the feed roller 21 interposed therebetween, a shaft 27 is provided between the side plates 11 and 11 in parallel with the feed roller 21, and the shaft 27 has a “<” shape. A letter-shaped holding plate 28 is pivotally supported. That is,
On the lower bent piece 28a of the holding plate 28, projecting pieces 28b projecting in the direction away from the feed roller 21 at both longitudinal ends,
28b is formed, and the shaft 27 is inserted through both projecting pieces 28b, 28b. Further, a torsion spring 29 is arranged on the opposite side of the feed roller 21 with the upper bending piece 28c of the pressing plate 28 sandwiched therebetween, and the torsion spring 29 causes the upper bending piece 28c to be always attached to the O-ring 26 of the feeding roller 21. It functions to make pressure contact. Therefore, the sheet material 15 drawn from the sheet roll 15
If a is interposed between the O-ring 26 and the pressing plate 28, the sheet material 15a is pressed against the feed roller 21, so that the sheet material 15a is sequentially pulled out from the sheet roll 15 as the roller 21 rotates. (See Fig. 6 (a)).

Further, a guide 30 is vertically arranged along the roller 21 between the feed roller 21 and the pressing plate 28, and the guide 30 feeds the sheet material 15 fed by the feed roller 21.
It serves to guide a vertically downwards. This guide 30
As shown in FIG. 2, the O is wound around the feed roller 21.
A notch 30a that opens upward is formed at a position corresponding to the position where the ring 26 is provided. And the feed roller 2
1 O-ring 26, as shown in FIG.
It is configured so as to project from the notch 30a toward the holding plate 28. That is, the guide 30 is the O of the feed roller 21.
It functions to allow the feeding of the sheet material 15a by the ring 26 and prevent the leading end of the sheet material 15a in the feeding direction from being caught in the feed roller 21.

(Sheet Material Cutting Mechanism) Below the feed roller 21, on the right side of the sheet material 15a droopingly fed from the roller 21, there is provided a fixed blade bracket 31 formed in an inverted "V" shape on both sides. Board 1
The shaft 32 is rotatably supported by a shaft 32 installed between the first and the first parts. That is, the lower bent piece 3 of the fixed blade bracket 31
1a is formed with projecting pieces 31b, 31b (only one is shown) projecting to the back side (the direction away from the sheet material 15a suspended from the feeding roller 21) at both ends in the longitudinal direction, and the shaft 32 has both projecting sides. It is inserted through the pieces 31b and 31b.
In the upper bent piece 31c of the fixed blade bracket 31,
Fixed blades 33 that are oriented toward the front panel 12 are arranged along the longitudinal direction.
The length dimension is set to be longer than the width dimension of a. In addition, the shaft 32 on which the fixed blade bracket 31 is pivotally supported,
A torsion spring 34 is interposed, and the spring 34 constantly urges the bracket 31 and the fixed blade 33 toward a rotary blade 36, which will be described later.

Below the pressing plate 28, there is a rotary blade mounting roller 35 which faces the fixed blade bracket 31 with the sheet material 15a hanging from the feed roller 21 interposed therebetween and which extends in parallel with the fixed blade bracket 31. It is rotatably installed between both side plates 11, 11. And on this roller 35,
A rotary blade 36 extending along the axial direction of the roller 35 is arranged with its blade edge protruding outward in the radial direction. The rotary blade 36 is arranged at a slight angle with respect to the axis of the roller, and when the rotary blade mounting roller 35 is rotated when cutting the sheet material 15a, the rotary blade 36 and the fixed blade 33 are separated from each other. , Are configured to sequentially abut from one end to the other end in the longitudinal direction.

Further, the shaft 37 of the rotary blade mounting roller 35 has a gear at the end projecting from one side plate 11 (the end where the gear 23 arranged on the shaft 22 of the feed roller 21 is arranged). 38 are provided. As shown in FIG. 3, the gear 38 is in common mesh with a gear 25 connected to the motor 24 and a gear 23 arranged on the shaft 22 of the feed roller 21 to drive the motor 24. As a result, the rotary blade mounting roller 35 rotates clockwise in FIG.

A cam 39 that rotates integrally with the roller 35 is provided at the inner shaft end of the rotary blade mounting roller 35 on the inner side of the side plate 11 (on the side opposite to the end where the gear 38 is provided).
As shown in FIG. 3, a projection 39a is formed on the outer periphery of the cam 39 so as to project outward in the radial direction.
Is set so as to contact the lower end of the lower bent piece 28a of the holding plate 28. Further, the protrusion 39a contacts the lower bent piece 28a of the holding plate 28 while the rotary blade 36 rotates and contacts the fixed blade 33 (while cutting the sheet material 15a). , Its formation range is set. Therefore, the rotary blade mounting roller 35 rotates,
When the protrusion 39a of the cam 39 contacts the pressing plate 28, the sixth
As shown in FIG. 7C, the holding plate 28 rotates counterclockwise about the shaft 27, the upper bending piece 28c separates from the O-ring 26, and the sheet material 15a is not 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, as a result of the upper bent piece 28c of the pressing plate 28 being separated from the O-ring 26, even if the feed roller 21 rotates, the sheet material 15a is slipped on the roller 21 and positive feed is imparted. Disappear. This allows the sheet material 15a to move under the action of connecting the rotary blade 36 and the fixed blade 33.
When the sheet is cut, the sheet material 15a does not move and the cut surface is not distorted, and a cut surface can be obtained.

A roller (not shown) having a diameter larger than that of the roller 35 is disposed on the opposite side of the rotary blade mounting roller 35 from the end portion where the cam 39 is disposed. Further, a projection 33a is formed at an axial end of the fixed blade 33 so as to project from the blade of the fixed blade 33 toward the rotary blade mounting roller 35. The projection 33a is formed by the elastic force of the torsion spring 34. Is always in contact with the roller (see FIG. 2).
As a result, a gap is defined between the rotary blade mounting roller 35 and the blade portion of the fixed blade 33 except when the rotary blade 36 and the fixed blade 33 are connected to each other, which allows the sheet material 15a to pass therethrough.

(About water tray) Below the fixed blade bracket 31, a water tray 40 that guides the sheet material 15a to a rolled hand towel manufacturing section 43 described later and receives water sprinkled from the water sprinkling pipe 41.
However, as it goes downward, it is arranged so as to be inclined downward so as to approach the front panel 12. This water dish 40
Is detachably mounted on the positioning member 62 of the rolled hand towel manufacturing section 43, and is configured to be easily detached from the manufacturing apparatus 9 for cleaning or maintenance (see FIG. 4). As shown in FIG. 2, the upper end of the water tray 40 faces the back side of the lower bent piece 28a of the fixed blade bracket 31 (opposite to the direction of the sheet material 15a feeding path). The sheet material 15a fed from above is reliably prevented from entering the back side of the water tray 40, and the sheet material 15a is guided to the front side of the water tray 40.

As shown in FIGS. 1 and 4, the 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 the rib bulges toward the front panel, and the front side of each rib 40b is connected by a dam member 40c. Further, a hole 40d is defined between the damming material 40c and the back plate 40a, and the hole 40d is a sheet material to which a part of the water sprinkled from the sprinkling pipe 41 is transferred to the rolled wet towel manufacturing section 43. It functions so as to be dropped on 15a.

(Sprinkling Pipe) As shown in FIG. 3, both side plates 11 and 1 on the front side of the water tray 40.
The water sprinkling pipe 41 is removably installed between the two. A plurality of water spray holes 41a directed to the water tray 40 are formed in the water spray pipe 41, and the water pumped from the water tank 17 through the pump 18 through the water spray holes 41a is transferred to the back plate 40a of the water tray 40. It is sprinkled towards. As a result, the sheet material 15a that hangs down from the feed roller 21 and is located on the front surface of the back plate 40a of the water tray 40 is provided with the moist air required as a hand towel (see FIG. 6 (b)).
Further, the water not absorbed by the sheet material 15a is stored in the water tray 4
From the hole 40d formed in the lower end portion of 0, a hand towel manufacturing section 43, which will be described later, is dropped onto the sheet material 15a to be transferred so as to make up for the lack of moist air in the water tray section.

A slot valve 42 that adjusts the pressure of water pumped from the pump 18 is provided in the supply pipe 19 that connects the discharge pipe 18b of the pump 18 and the sprinkler pipe 41 to each other.
Further, a check valve 90 is provided in the supply pipe 19 so that all the water remaining in the water sprinkling pipe 41 and the supply pipe 19 when the water sprinkling is finished does not flow back to the pump 18. That is, if there is no water remaining in the water sprinkling pipe 41 and the supply pipe 19, it takes time for the water pumped by the pump 18 to reach the water sprinkling pipe 41 at the time of the next water sprinkling, and there is a deviation in the water sprinkling timing. Therefore, by leaving water in the sprinkling pipe 41 and the supply pipe 19 at all times, it is possible to effectively prevent the deviation of the sprinkling timing.

(Regarding the rolled hand towel manufacturing section) The pair of guide rails 5 inclined downward as they are separated from the front panel 12 are provided on the lower side plates 11 and 11 which are separated from the cutting mechanism section of the sheet material 15a by a predetermined distance.

While being separated from the conveying surface of the endless belt 47 by a predetermined distance,
The drive roller 46 is extended from the position where the first fixed roller 48 is disposed so as to surround the drive roller 46.

An end portion of the upper bracket 52 on the downstream side in the traveling direction of the endless belt 47 is provided with an inclination that is closer to the endless belt 47 on the downstream side of the third fixed roller 50. The endless belt 47 passing between the first fixed roller 48 and the second fixed roller 49 is set to be directed to the inclined portion 51a of the fixed belt 51 extending along the inclined portion. Therefore, the endless belt 4
The front end of the sheet material 15a transferred by 7 is shown in FIG.
As shown in (d), the inclined portion 51a of the fixed belt 51 is surely contacted. Further, the third fixed roller 50 is the fixed belt 5
Since it is arranged on the upstream side of the first inclined portion 51a,
The leading end of the sheet material 15a that comes in contact with the fixed belt 51 and is folded back in the direction opposite to the transport direction has the third fixed roller 50.
The roll winding start end is surely formed by abutting against and being wound inside. It is possible to arbitrarily set the diameter dimension of the "rolling hand towel" to be manufactured by configuring the distance between the endless belt 47 and the fixed belt 51 to be adjustable.

Inverted L-shaped positioning members 62, 62 (only one of which is shown) for mounting the water tray 40 are arranged at positions on the support frames 44, 44 that are close to the driven rollers 45. Further, a bracket 63 having a hook-like tip is erected at a position below the driven roller 45 of the lower protrusions 44b and 44b of the support frames 44 and 44, and the tip of the bracket 63 has the guide rail 54, 54
The rolled hand towel manufacturing section 43 is positioned by being locked to the tip of the. Further, when the endless belt 47 is driven to run, a reaction force is applied to rotate the rolled hand towel manufacturing section 43 counterclockwise about the drive roller 46.
The bracket 63 also has a function of preventing the manufacturing unit 43 from rotating due to this reaction force. In the drawings, reference numeral 64 indicates a guide plate that guides the "rolling hand towel" manufactured by the rolling hand towel manufacturing section 43 to a tray / cover 58 which will be described later.

It is in the state immediately after being separated from. 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 rotate in mutually opposite directions via the gears 25, 38 and 23. As a result, the sheet material 15a is pulled out from the sheet roll 15 rotatably housed in the roll holder 16, and the sheet material 15a is fed vertically downward along the guide 30 arranged in the vicinity of the feed roller 21. To be done.

Here, since the sheet material 15a is fed by the plurality of O-rings 26 wound at a predetermined interval in the longitudinal direction of the feed roller 21, the sheet material 15a is always in a normal state (the sheet material 15a is fed). It can be fed to the cutting mechanism portion in a state in which it is not inclined with respect to the direction. Also, sheet material 1
5a is provided with a curl in the direction in which the feed roller 21 is wound. However, as shown in FIG. 2, since the guide 30 is arranged close to the feed roller 21, the sheet material 15a
The tip is guided downward without being caught by the roller 21.

Then, the sheet material 15a is fed downward by a predetermined length, passes through the gap defined between the fixed blade 33 and the rotary blade mounting roller 35, and hangs down to the front surface of the water tray 40. The pump 18 is energized at the timing. As a result, as shown in FIG. 6 (b), the water tank 17
The water pumped from the pump 18 to the water spray pipe 41 through the pump 18 is sprayed on the sheet material 15a through the water spray holes 41a. Since the upper end of the water tray 40 is located on the back side of the lower bent piece 31a of the fixed blade bracket 31 (see FIG. 2), the sheet that has passed between the fixed blade 33 and the rotary blade mounting roller 35. It is possible to reliably prevent the tip of the material 15a from entering the back side of the water tray 40.

When the rotary blade mounting roller 35 rotates to a predetermined angle,
A projection 39a of a cam 39 arranged at the shaft end of the roller 35
Comes into contact with the holding plate 28, and the upper bent piece 28 of the holding plate 28
c is separated from the feed roller 21 (see FIG. 6 (c)). This prevents the sheet material 15a from being positively fed. When the rotary blade mounting roller 35 further rotates, the rotary blade 36 comes into contact with the fixed blade 33, and the sheet material 15a located between the blades 36, 33 is cut. The pump 18 is stopped at an appropriate timing to stop the water spray from the water spray pipe 41.

When the sheet material 15a having a predetermined length is cut, the upper portion of the sheet material 15a falls in the direction away from the water tray 40 and comes into contact with the endless belt 47 of the rolled hand towel manufacturing section 43. At this time, since the upper portion of the sheet material 15a falls down while contacting the water spray pipe 41, the water spray pipe 41
The water droplets adhering to the water spray holes 41a can be wiped (see FIG. 6 (c)). Since the endless belt 47 is driven to travel, the sheet material 15 a that has fallen onto the belt 47 is transferred by the endless belt 47. At this time, since the lower end portion of the sheet material 15a is located at the lower bulge portion of the rib 40b in the water tray 40, the lower end portion is bent, and the leading end of the sheet material 15a in the traveling direction has a double sheet. It will be in a state of overlapping. Then, when the leading end of the sheet material 15a is transferred to the position where the first fixed roller 48 and the second fixed roller 49 are arranged in this state, the endless belt 47 passing between the rollers 48 and 49 is inclined. As a result, as shown in FIG.
As shown in (d), it abuts on the inclined portion 51a of the fixed belt 51.

Since the endless belt 47 is continuously running, the leading end of the sheet material 15a that abuts the fixed belt 51 is folded back in the direction opposite to the transport direction, and then rolled inward to form the start end of the roll winding. . At this time, temporarily the fixing belt 5
After the leading edge of the sheet material 15a that has abutted against 1 is folded back in the direction opposite to the transport direction, and if the feeding proceeds without being rolled inward, the end moves in the direction opposite to the transport direction and is rolled. Disappear. However, as described above, since the third fixed roller 50 is disposed on the upstream side of the fixed belt 51 with which the leading end of the sheet material 15a abuts, the sheet material 15 is not provided.
Even if a moves in the direction opposite to the transport direction, the end portion comes into contact with the third fixed roller 50 and is wound inside, so that the start end of the roll winding can be reliably formed.

The sheet material 15a on which the starting end of the roll winding is formed is
While being transferred between the fixed belt 51 and the endless belt 47, it is rolled and wound to a predetermined diameter. As shown in FIG. 6 (d), the rolled sheet material 15a falls from the opening 12b of the front panel 12 to the saucer / cover 58 through the guide plate 64 provided on the guide rails 54, 54. To do. Therefore, as shown in FIG.
If you open, you can take out the rolled towel.

Effect of the Invention As described above, according to the rolled hand towel manufacturing apparatus of the present invention, the sheet material pulled out from the supply source can be always fed in a normal state, so that the cut surface of the sheet material becomes oblique. It does not spoil the appearance of "rolled towel". In addition, since the guide is arranged close to the feed roller and the upper end of the water tray faces the back side of the fixed blade, even if the sheet material has a strong curl, the sheet material is It can be effectively prevented from being caught in the water or entering the back side of the water tray. Further, since the water tray can be removed from the manufacturing apparatus, there is an advantage that cleaning and maintenance can be easily performed.
