DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a rolled towel by extracting a sheet material from a towel roll wound in a roll shape, cutting the sheet material into a predetermined length, and winding one cut sheet material in a roll shape. The present invention relates to an automatic towel manufacturing apparatus.

[0002]

2. Description of the Related Art In a variety of food-related stores, "Oshibori" is often provided to customers as part of customer service. Conventionally, as this "towel", a "roll towel" of a towel cloth or a "fold towel" obtained by folding a sheet material is generally used. Toweling rolls can be repeatedly used and are preferable from the viewpoint of resource saving, but on the other hand, if the reprocessing is incomplete, they have a problem in hygiene such as remaining dirt or giving off odor. On the other hand, folding towels are sanitary because they are disposable only once, but the costs are relatively high because they are individually wrapped and delivered by a vendor. Moreover, for customers who are accustomed to using the conventional toweling roll towel, the flat towel is inferior in use.

On the other hand, there has been developed a small roll towel manufacturing apparatus which manufactures and supplies on-the-spot roll towels made of inexpensive and disposable sheet material such as paper or non-woven fabric as needed. For example, a roll towel manufacturing apparatus described in Japanese Utility Model Publication No. 5-33321 or the like includes a roll holding unit that holds a towel roll in which a sheet material is wound in a roll shape on a cylindrical paper core so as to be rotatable substantially horizontally, Feeding means for pulling the sheet material forward from the towel roll and sending it further downward; watering means for giving wetness to the pulled-out sheet material; and feeding the wet-applied sheet material a predetermined length from the leading end. And a forming means for winding the cut one sheet material into a roll to form a substantially column-shaped towel. Since the operation of each of the above means is automatically controlled in conjunction with each other, if the user presses the towel supply button on the operation unit provided on the outer box, a roll towel made of a sheet material at the outlet of the forming means is pressed. Obtainable.

[0004]

The usual maintenance work performed by the user in this type of roll towel manufacturing apparatus is to replace the towel roll with a new towel roll when the towel roll is used up, and to add water for adding water. (Generally, water to which a predetermined disinfecting solution has been added) is to be replenished when it runs out. When replacing the towel roll, it is necessary to perform a troublesome operation such as mounting the towel roll at a predetermined position of the roll holding means, extracting the sheet material, and inserting the leading end of the sheet material into a predetermined gap of the feeding means.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an apparatus for manufacturing a roll towel that simplifies an operation for mounting a towel roll.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a roll holding device for rotatably holding a towel roll formed by winding a belt-shaped sheet material into a roll shape. Means, feeding means for drawing the sheet material from the towel roll held by the roll holding means, cutting means for cutting the drawn sheet material from the leading end at a position of a predetermined length, and one of the cut sheets In a roll towel manufacturing apparatus comprising: a forming means for winding a sheet material into a roll to form a roll towel, the feeding means includes: a) a guide portion for guiding the sheet material fed from the towel roll substantially horizontally; b) a roller whose upper end is provided at substantially the same height as the guide portion, forward of the guide portion in the feeding direction; andc) a rear surface of the roller so as to cover the upper portion of the roller forward of the roller in the feed direction. The roller A pressing member which is Chodo freely disposed in a direction to contact with or separate from the outer peripheral surface, and a biasing member for biasing the d) presser member in the roller direction, comprising the.

In the apparatus for manufacturing towels according to the present invention, when replacing the towel roll, the user accommodates the towel roll in a predetermined position of the roll holding means, lifts the pressing member by hand, and lifts the back surface of the pressing member. Separate from the roller top. Then, the leading end of the sheet material pulled out from the towel roll is extended from the guide portion and placed on the upper end of the roller.
When the pressing member is released, the pressing member rotates in the direction of the roller by the urging force, and the leading end of the sheet material is pressed against the roller by the pressing member. Then, when the roller rotates,
Due to the frictional force between the sheet material and the roller, the leading end of the sheet material is fed forward according to the rotation of the roller.

[0008] In the roll towel manufacturing apparatus of the present invention,
The cutting means may include a fixed blade and a rotary blade disposed below the roller, and the pressing member may have a back surface formed in a curved shape corresponding to an outer peripheral surface of the roller. That is, in this configuration, when the roller rotates, the sheet material is fed so as to hang downward from the front of the roller along the curved surface on the back surface of the pressing member. Then, the sheet material intervenes between the rotating blade and the fixed blade of the cutting means and is rotated so that the rotating blade comes into contact with the fixed blade, whereby the sheet material sandwiched therebetween is cut.

In the apparatus for manufacturing a roll towel according to the present invention, the pressing member swings in conjunction with the operation of the rotary blade of the cutting means, and releases the pressing of the sheet material immediately before the rotary blade comes into contact with the fixed blade. It is preferable to adopt a configuration in which: That is, when the pressing member rotates upward and the pressing of the sheet material is released, the frictional force between the sheet material and the roller is weakened, and the feeding of the sheet is stopped even when the roller is rotating. Therefore, it is possible to prevent a problem that the cutting line is distorted or bent due to the feeding of the sheet material during the cutting operation.

Further, in the roll towel manufacturing apparatus according to the present invention, when the pressing member is rotated upward in conjunction with the operation of the rotary blade of the cutting means, the lower end portion thereof is rotated to hang down. In this case, the sheet material may be brought into contact with the portion immediately above the cutting portion and the sheet material may be pushed backward. That is, when the sheet material is slightly pushed backward just above the cutting line, an appropriate tension is applied to the hanging sheet material. Thereby, good cutting can be performed when the rotary blade hits, and it is possible to prevent the occurrence of uncut portions and the bending of the cutting line.

[0011]

According to the roll towel manufacturing apparatus of the present invention, the user automatically feeds the sheet material only by placing the leading end of the sheet material pulled out from the towel roll on the feed roller. Is set to a predetermined position. Therefore, it is possible to save the labor of the user's work, and it is also possible to prevent a mistake in setting the sheet material when the towel roll is attached.

And a forming means 50 which is wound into a roll and formed into a substantially cylindrical shape. The operation of each of the above-described units is controlled by a control unit including an electric circuit unit (not shown).

As shown in FIG. 2, an operation unit 2 provided with a plurality of buttons and display lamps is provided on a front plate 1 of an outer case of the roll towel manufacturing apparatus. Below the front plate 1, a pan / front cover 3 is provided so as to be able to butterfly forward about a shaft 3 a attached to the lowermost end substantially in the width direction. The tray / front cover 3 can be tilted forward to open the squeezing supply port 5 only when the apparatus is used, as shown in FIG. The upper cover 4 of the outer box is detachably attached, so that the user can easily replace the towel roll 11 and refill the water in the water tank 31 with the user.

Next, the configuration of each means of the above-mentioned roll towel manufacturing apparatus will be described in more detail. (I) Roll holding means 10 As shown in FIG. 1 and FIG. 3, an arc is formed between both side supporting plates 12 erected so as to face inside the both side plates 6 of the outer box. A towel roll storage chamber 13 having a bottom wall 13a and an open top is formed with the top cover 4 removed. The towel roll 11 is formed of a paper-shaped core 11b whose one end in the short direction of a strip-shaped sheet material 11a is cylindrical.
And the sheet material 11a is wound around it in a roll shape. When the towel roll 11 is stored in the towel roll storage chamber 13, the inner protruding portion of the resin roll holder 11c is rotatably loosely fitted to the opening at both ends of the core 11b. At this time, the outer protrusions of the roll holder 11c protrude outward from both end surfaces of the towel roll 11.

A substantially W-shaped groove 14 having an arc-shaped bottom surface is formed in each of the support plates 12 on both sides, and the auxiliary groove 14b on the front plate 1 side is slightly larger than the holder support groove 14a on the rear side. It is provided at a high position. Towel roll 11
Are mounted such that the outer protrusions of the roll holder 11c protruding outward from both ends thereof fit into the holder support grooves 14a. A small switch 1 is provided on the bottom surface of the holder support groove 14a of one side support plate 12 (left support plate in this embodiment).
5 are buried. The movable piece 15a of the switch 15 projects above a small hole formed in the bottom surface of the holder support groove 14a, and as shown in FIG.
When the switch 1 is not mounted, the movable piece 15a protrudes upward and the contact of the switch 15 is open. FIG.
(A) As shown in FIG.
When properly mounted on 4a, the outer projection of the roll holder 11c presses the movable piece 15a to close the contact of the switch 15. Further, a front wall of the towel roll storage chamber 13 has an extending portion 13b that extends substantially horizontally to the vicinity of a later-described feed roller 21.
And forms a part of a feeding path through which the sheet material 11a drawn from the towel roll 11 passes.

(II) Feeding Means 20 As shown in FIG. 1 and FIG. 4, below the leading end of the extending portion 13b, a feeding roller 21 is installed substantially horizontally between the support plates 12 on both sides. The rotation shaft 22 of the feed roller 21 is shown in FIG.
And a counterclockwise direction (direction of arrow E in FIG. 4) by a rotation transmitting mechanism such as a feeding motor and gears not shown in FIG.
It is designed to rotate. A plurality of rubber rings 21 a protruding in the radial direction are provided around the feed roller 21 at predetermined intervals in the extending direction of the rotating shaft 22. Further, a resin pressing member 23 that swings within a predetermined range around a shaft 23a attached to the support plate 12 on both sides is provided so as to cover the upper side and the front side of the feed roller 21. The pressing member 23 is urged by a torsion coil spring 23b in the direction of the feeding roller 21 with an appropriate force, whereby the lower surface of the pressing member 23 contacts the ring 21a of the feeding roller 21 and gently presses it. I have. Also, the feed roller 21
A fixed guide plate 24 that is inclined downward toward the front plate 1 is provided at the front lower side of the front side, and assists the sheet material to hang down without being caught below the feed roller 21.

(III) Watering means 30 As shown in FIG. 1, a tank storage chamber 32 having an open top for holding the water tank 31 in an inverted state is formed behind the towel roll storage chamber 13. I have. When the water tank 31 is inverted and mounted in the tank storage chamber 32, the water supply port 31a is opened, and the water in the water tank 31 is discharged to the recess 32a at the bottom of the tank storage chamber 32. I have. At this time, the water level in the recess 32a is detected by the water level sensor 32b rising from the bottom of the recess 32a.
A suction pipe 33a of a pump 33 is connected to the bottom of the recess 32a, and a discharge port of the pump 33 is connected to a temperature control unit 35 and an injection amount adjusting section 36 via a water supply pipe 34. The temperature control unit 35 holds a predetermined amount of water therein, and can heat or cool the water. The injection amount adjusting unit 36 is composed of a manual valve or the like, and
The amount of water injected from 7 can be adjusted.
Below the fixed blade holder 41, a water receiving wall 38 having a plurality of grooves extending in the vertical direction is disposed in an inclined manner. Further, in front of the water receiving wall 38, a nozzle 37 having a plurality of injection holes toward the water receiving wall 38 is provided on both sides of the support plate 12.
The water supply pipe 34 is connected to the nozzle 37 via the injection amount adjustment unit 36.

(IV) Cutting Means 40 As shown in FIGS. 1 and 4, a fixed blade holder 41 is provided between both side support plates 12 directly below the feed roller 21. At 41, fixed blades 42 longer on both sides than the width of the sheet material are attached toward the front. The fixed blade holder 41 is urged toward the front plate 1 by a spring (not shown) with respect to the support plates 12 on both sides. On the other hand, at a position facing the fixed blade 42 with a sheet material hanging down from the feed roller 21 interposed therebetween, a rotary blade holder 43 is installed between the both side supporting plates 12 so as to be rotatable substantially horizontally. The rotary blade 44 is mounted to extend in the axial direction at a predetermined angle with respect to the rotation axis of the rotary blade holder 43,
When the rotary blade holder 43 is rotated at the time of cutting the sheet material, the rotary blade 44 advances from one end in the axial direction to the other end while sequentially contacting the fixed blade 42. As a result, the sheet material sandwiched between them is cut along a substantially horizontal cutting line. When the rotary blade 44 comes into contact with the fixed blade 42, the fixed blade holder 41 is pushed backward and slightly retreats by overcoming the force of the spring biasing the fixed blade holder 41. Thereby, the blades can be prevented from being damaged because unnecessarily large force is not applied to the rotary blades 44 and the fixed blades 42.

A cam 4 having a predetermined shape is provided at the end of the rotary shaft of the rotary blade holder 43 projecting outward from the one side support plate 12.
5 and a timing cam 46 partly recessed on the inner peripheral side are attached. The lower end of the pressing member 23 is close to the outer peripheral edge of the cam 45, and when the rotating blade holder 43 rotates and the protrusion of the cam 45 reaches upward, the pressing member 2
3 and is pushed upward. Then, the pressing member 23 slightly rotates in the counterclockwise direction (the direction of the arrow G in FIG. 4) about the shaft 23a. As a result, the lower end edge of the pressing member 23 extending in the horizontal direction comes into contact with the sheet material hanging forward (to the right in FIGS. 1 and 4), and slightly pushes the sheet material upside down. The contact line is located slightly above the cutting line, and when the sheet material is pushed up, the sheet material hanging down from the contact line is tensioned, so that the cutting can be performed neatly. When the holding member 23 rotates as described above,
The force of pressing the ring 21a of the feed roller 21 is released, and the sheet material above the contact line is pulled slightly downward. For this reason, even if a slight distortion occurs in the feeding of the sheet material due to the imbalance of the feeding in the left-right direction in the feeding means 20, the distortion can be corrected.

The movable piece of the switch 47 is fixedly mounted on the outer peripheral edge of the timing cam 46 so that the rotary blade holder 43 rotates and the concave portion of the timing cam 46 reaches the movable piece of the switch 47. The movable piece is activated to open the contact of the switch 47. This makes it possible to detect that the fed sheet material has reached the predetermined position, and determine the timing of jetting water from the nozzle 37.

(V) Forming means 50 As shown in FIGS. 1 and 5, below the water receiving wall 38, there are provided two rollers 51 and 52 rotatably provided between the support plates 12 on both sides. A transport conveyor around which a rubber belt 53 having a predetermined width is wound is installed to be inclined downward from the front plate 1 side toward the rear side. The rotating shaft of the lower driving roller 51 is driven to rotate clockwise (in the direction of arrow H in FIG. 5) by a rotation transmitting mechanism such as a conveying motor and gears (not shown), and the upper driven roller 52 is driven by a driving roller. With the rotation of 51, it rotates in the same direction via the belt 53. A fixed belt 54 made of rubber is provided on the outer peripheral side of the belt 53 below the conveyor, keeping an appropriate gap from the belt 53. At the upper end of the fixed belt 54, a regulating plate 55 for regulating the height of the entrance is provided, also serving as a blanket for fixing the upper end of the fixed belt 54. In addition, while the belt 53 is relatively hard so that the inward bending is small, it is preferable that the fixed belt 54 bend appropriately.

Appropriate irregularities are formed on the inner side of the fixed belt 54 (the surface facing the belt 53), and give an appropriate friction to the sheet material 11a moving in the gap between the belt 53 and the fixed belt 54. . On the other hand, a metal guide plate 56 is disposed near the end of the fixed belt 54 while maintaining a gap substantially equal to the gap between the belt 53 and the fixed belt 54 between the belt 53 and the fixed guide 54. The guide plate 56 is attached to a support member 57 fixed to the side support plate 12 by being urged toward the belt 53 by coil springs 58a and 58b at four corners thereof. Therefore, when the towel sheet S wound in a roll shape reaches the gap between the guide plate 56 and the belt 53, the guide plate 56 is pushed downward by the weight of the towel sheet S and the pressure in the outer circumferential direction, and the guide sheet 56 is guided. The gap between the plate 56 and the belt 53 is widened.
The upper end of the guide plate 56 (that is, the exit side in the feeding direction of the belt 53) is bent obliquely downward toward the towel supply port 5.

Next, the operation of the roll towel manufacturing apparatus having the above configuration will be described in the order of handling. First, when the towel roll 11 is mounted, as shown in FIG. 3A, the roll holders 11c on both sides loosely fitted to the center 11b of the towel roll 11 are placed in the holder support grooves 14a. Then, the movable piece 15a is pushed in, the contact of the switch 15 is closed, and it is detected that the towel roll 11 is attached. The user can remove the sheet material 1 from the towel roll 11.
1a is pulled out, and the pressing member 23 is pivoted around the shaft 23a.
Is lifted, the leading end of the sheet material 11a is placed on the feed roller 21, and the pressing member 23 is returned to the original position. As described above, since the pressing member 23 is urged by the torsion coil spring 23b, the sheet material 11a is sandwiched between the lower surface of the pressing member 23 and the ring 21a of the feeding roller 21. On the other hand, in the tank storage chamber 32, for example, a water tank 31 filled with water containing a sterilizing component is stored upside down as shown in FIG.

Thus, the towel roll 11 and the water tank 3
When the user presses the squeeze supply button 2a in the operation unit 2 in a state where 1 has been appropriately set, a feed motor (not shown) is driven, and the feed roller 21 moves in the direction of arrow E in FIG. Rotated. The leading end of the sheet material 11a is sandwiched between the ring 21a of the feed roller 21 and the pressing member 23. The lower surface of the pressing member 23 is relatively smooth, while the ring 21a has a relatively large frictional force. Sheet material 11a
Give to. For this reason, with the rotation of the feed roller 21, the sheet material 11a is further fed substantially vertically downward from the horizontal front. Then, it passes through the gap between the holding member 23 and the fixed guide plate 24, and is further sent to the gap between the fixed blade 42 and the rotary blade holder 43. That is, when the towel roll 11 is replaced, the user simply pulls out the tip of the sheet material 11a lightly and places it on the feed roller 21, so that the sheet material 11a is automatically sent to an appropriate feeding path. Therefore, troublesome work of mounting the sheet material is unnecessary.

The length of the sheet material fed by one operation of the squeezing supply button 2a, that is, the number of rotations of the feeding roller 21, is predetermined. Therefore, the sheet material 11a
Is suspended through the gap between the fixed blade 42 and the rotary blade holder 43, and stops when it reaches a predetermined position determined by the number of rotations of the feed roller 21. When the squeezing supply button 2a is operated for the first time after the towel roll 11 is mounted as described above, the length of the sheet material 11a placed on the feeding roller 21 from the leading end to the cutting line is reduced. Since the feed is shortened by the length of the sheet material 11
The position of the tip when the feeding of a is stopped is slightly higher than in the subsequent cases.

When the feed roller 21 is rotated as described above, the rotary blade holder 43 rotates clockwise (in the direction of arrow F in FIG. 4) in synchronization with the rotation of the feed roller 21. Then, when the leading end of the sheet material 11a reaches the rotation position reaching the front of the nozzle 37, the concave portion of the timing cam 46 reaches the movable piece of the switch 47, and the switch 47 is opened. As a result, the pump 33 is driven and the water tank 31
The water sucked from the temperature control unit 3 through the water pipe 34
5 is sent. Pressed by this water already temperature control unit 3
The water accumulated inside 5 is sent to the nozzle 37 via the injection amount adjusting unit 36. Since the water stored in the temperature control unit 35 is heated or cooled in advance according to the setting of the user, hot or cold water is jetted from the jet holes of the nozzle 37 toward the sheet material 11a. As the sheet material 11a is fed, the spraying position of the jetted water sequentially moves, so that the entire sheet material for forming the towel is moistened evenly. The water that did not fall on the sheet material 11a or dripped from the sheet material 11a hits the water receiving wall 38, flows down along the groove, and falls on the lower belt 53.
Further, the water dropped along the belt 53 is collected in the water collecting tray 7 below.

When the leading end of the sheet material 11a hangs down to a predetermined position, the projecting portion of the cam 45 just pushes up the pressing member 23. Thereby, as described above, the pressing member 23 slightly rotates around the shaft 23a in the direction of arrow G in FIG.
The lower end portion contacts the sheet material 11a and pushes up rearward. Immediately thereafter, the rotary blade 44 sequentially contacts the fixed blade 42 from one end to the other end, and as a result, the sheet material 11a is cut substantially horizontally and smoothly.

As shown in FIG. 5, the sheet material 11a cut to a predetermined length is slid down onto the belt 53 from the lower end thereof, and is conveyed by the belt 53. Sheet material 11
When the leading end of the sheet a passes through the narrow gap between the regulating plate 55 and the belt 53, the upper surface of the sheet material 11a comes into contact with the regulating plate 55, and a force is applied in a direction opposite to the conveying direction by friction.
Therefore, immediately after the leading end of the sheet material 11a passes through the narrow gap, the leading end is folded upward. The belt 53 is running continuously, while the fixed belt 54 applies an appropriate frictional force to the upper surface of the sheet material 11a, so that the sheet material 11a is rolled up around the previously folded portion.

Since the fixed belt 54 has an appropriate stretching force, the fixed belt 54 and the belt 53 are formed by the weight of the rolled towel sheet S and its mechanical pressing force.
Is appropriately widened, and the towel sheet S is conveyed while rolling in the gap. As shown in FIG.
When the toweling sheet material S reaches the lower end of the guide plate 56, the coil springs 58a and 58b contract and the guide plate 56 hangs down appropriately. Thereby, the belt 53 and the guide plate 56
Is widened, and the winding of the towel sheet S that has been strongly wound until immediately before is slightly loosened. As shown in FIG. 6 (b), the towel sheet S is wound around the guide plate 56 in a loosened state.
And falls downward (see arrow J in FIG. 6B). Since the towel supply port 5 is opened below the towel sheet S, the towel sheet S falls through the towel supply port 5 onto the lower receiving / front cover 3. Therefore, it is possible to provide a fluffy towel having a moderately loose wound state.

One roll towel is provided by the above series of operations. The operation unit 2 is provided with a button for setting the number of roll towels to be provided. When provision of two or more roll towels is set by operating the button, the above operation is performed according to the number. Repeated continuously,
A predetermined number of towels are completed.

The production of the rolled towel is repeated in this manner,
When the sheet material of the towel roll 11 prepared first reaches the end, the feeding roller 21 pulls the core 11b through the sheet material in the direction of arrow D in FIG. 3B. Then, the core 11b and the roll holder 11c are pulled up, and the movable piece 15a of the switch 15 pops out. As a result, the switch 15 is opened, and the running out of paper is detected. In response to this, the out-of-paper indication lamp in the operation unit 2 is turned on, so that the user can immediately recognize the out-of-paper condition. In addition, the operation of the feeding motor is stopped simultaneously with the detection of the out of paper. For this reason, the rotation of the feed roller 21 is stopped, and the pulled roll holder 11c remains in the auxiliary groove 14b.

The above embodiment is merely an example, and it is apparent that changes and modifications can be made within the spirit of the present invention.
