FIG. The water tank T is a container for storing water for imparting moisture to the wet towel M, and is disposed so as to be freely detachable on the back side of the main body 2.

Next, with reference to FIG. 2, the electrical structure of the rolled towel manufacturing apparatus 1 is demonstrated. 2 is a block diagram schematically showing the electrical configuration of a roll towel manufacturing apparatus (1). The control circuit C is provided with a CPU 71, a ROM 72, a RAM 73, various drive circuits 81 to 86, various control circuits 87 and 88, and the like. Interconnected through.

The CPU 71 is an arithmetic unit that controls each element connected by the bus line 74 so that the scroll can perform the manufacture of the towel M by the roll towel manufacturing apparatus 1. The ROM 72 is a memory in which the control program executed by the CPU 71, fixed value data, and the like are stored and cannot be rewritten. The program shown in FIG. 7 is stored in the ROM 72. The RAM 73 is a memory for rewriting and storing various data when the control program is executed.

The ROM 72 stores a time parameter table 72a and a flow rate parameter table 72b. The time parameter table 72a shows the thickness t and the length L of the sheet material S, the waiting time T _s at the start, the waiting time T _c at the start, and the operating time T _m at the cutting. As a table storing the correspondence relationship (see FIG. 8), the CPU 71 drives the injection pump 83a of the watering means 40 (waiting time and driving) based on the contents of this time parameter table 72a. Time).

In addition, the thickness t means the thickness t of the sheet | seat material S set by the thickness conversion switch 70 (refer FIG. 6B) mentioned later, and the length L is the length setting dial 80 mentioned later. 6b) refers to the cutting length of the sheet material S set, for example, when the thickness t is set to "thick" and the length L is set to "30 cm", the waiting time T at the start (T). _s ) has a value of "100 ms" (see FIG. 8).

The flow rate parameter table 72b is a table storing the correspondence between the thickness t and the length L of the sheet material S, the driving force P _p at the inlet, and the driving force P _c at the cutting (Fig. 9). The CPU 71 controls the driving (spraying amount, etc.) of the injection pump 83a of the watering means 40 based on the contents of the flow rate parameter table 72b.

In addition, the minimum value and the maximum value are defined in the driving force P _p at the time of insertion and the driving force P _c at the cutting, respectively (see FIG. 9), and these minimum and maximum values are described below with the flow rate adjusting dial 60 (see FIG. 6A). Correspond to the lower limit Min and the upper limit Max respectively. That is, when the flow rate adjusting dial 60 is set to the lower limit value Min or the upper limit value Max, the values of the driving force P _p at the inlet and the driving force P _c at the cutting are the minimum value or the maximum value. When 60 is set between the lower limit Min and the upper limit Max, the values of the driving force P _p at the time of pulling and the driving force P _c at the cutting are determined at the same ratio as the flow rate adjusting dial 60.

For example, in the case where the movable range from the lower limit Min to the upper limit Max of the flow regulating dial 60 is set to 100, when the flow regulating dial 60 is set to 30% of the movable range, the driving force at the time of pulling in The value of P _p and the driving force P _c at the cutting is "minimum value + (maximum value-minimum value) x 0.3". Thus, for example, in the flow rate parameter table 72b, when the thickness is set to "thickness", the length L is set to "30 cm", and the flow rate adjusting dial 60 is set to 30% of the movable range, The value of the driving force P _p is "178 (= 160 + (220-160) x 0.3) pulse / s", and the value of the driving force P _c at the time of cutting is "240 (= 225 + (275-225) x 0.3) Pulse / s ", respectively.

Here, it returns to FIG. 2 and demonstrates. The RAM 73 is provided with a sheet thickness flag 73a and a sheet length memory 73b. The sheet thickness flag 73a is a flag for storing the thickness t of the sheet material S. The sheet thickness flag 73a is updated to "0" or "1" according to the setting state of the thickness conversion switch 70 (see FIG. 6B) described later. do. That is, the value of the sheet thickness flag 73a is updated to "0" when the thickness conversion switch 70 is converted to "thick" side, and the sheet thickness when the thickness conversion switch 70 is converted to "thin" side. The value of the flag 73a is updated to "1".

On the other hand, the sheet length memory 73b is a flag for storing the length L of the sheet material S, and is " 0 " to " 5 " depending on the setting state of the length setting dial 80 (see Fig. 6B) described later. Is updated to the range of. That is, when the length setting dial 80 is set to "18cm", the value of the sheet length memory 73a is updated to "0", and the setting value by the length setting dial 80 increases by "6 cm" from that state. Each time, the value of the sheet length memory 73a is added by "1". Therefore, when the length setting dial 80 is set to "48cm", the value of the sheet length memory 73a is updated to "5".

In addition, the CPU 71 is provided with the interrupt terminal 71a as shown in FIG. The interrupt terminal 71a is configured to input a detection signal 93 output from the overcurrent detection circuit 81b when a current (overcurrent) of a specified value or more flows into the supply motor 81a, and detects overcurrent according to detection of the overcurrent. Time processing (interrupt processing) is executed immediately.

The feeding motor driving circuit 81 is a circuit for driving control of the feeding motor 81a according to the instruction from the CPU 71, and the feeding motor 81a provides a rotational force to the driving roller 23 (see Fig. 3). It is a motor. By driving the feeding motor 81a, the drive roller 23 rotates by a predetermined rotational speed, and the sheet material S is taken out from the towel roll R by a length of a predetermined dimension.

The supply motor drive circuit 81 includes an overcurrent detection circuit 81b. The overcurrent detection circuit 81b is a circuit for outputting the detection signal 93 to the interrupt terminal 71a of the CPU 71 when the overcurrent flows to the supply motor 81a. The overcurrent detection circuit 81b monitors the current value flowing to the feed motor 81a, and when the current value is above a specified value, interrupts the generation of overcurrent and outputs the detection signal 93 to the CPU 71. It is composed.

In addition, the overcurrent flowing to the feeding motor 81a means that the sheet | seat material S of the towel roll R reached | attached the end. That is, the roll rotation guide Ra inserted in the center of the towel roll R is regulated by the second side wall member 13b of the guide groove 13 in the direction in which the sheet member S is drawn out as described later. (See FIG. 3). Therefore, when the sheet material S of the towel roll R reaches the end, the rotational resistance of the drive roller 23 becomes large according to the increase in the withdrawal resistance of the sheet material S. FIG. As a result, as the load of the feeding motor 81a increases, a current (overcurrent) of a specified value or more flows into the feeding motor 81a.

The cutting motor driving circuit 82 is a circuit for driving control of the cutting motor 82a according to an instruction from the CPU 71, and the cutting motor 82a supplies a rotational force to the rotary knife 32 (see FIG. 3). It is a motor. The rotary knife 32 is rotated by driving the cutting motor 82a at a predetermined timing interlocked with the above-described feeding motor 81a, and the sheet material S drawn out from the towel roll R is of predetermined dimension length from the tip end. Is cut at the position of.

The injection pump driving circuit 83 is a circuit for driving control of the injection pump 83a in accordance with the instruction of the CPU 71, and the injection pump 83a sprays water sucked from the water tank T (see FIG. 3). It is a pump for sending to the part 42 (refer FIG. 3). By driving the injection pump 83a, water is sprayed from the spraying part 42 with the sheet material S taken out from the towel roll R, and the roll gives moisture to the towel.

Here, the driving force and the injection time of the injection pump 83a are related to the thickness t and the length L of the sheet material S in the time parameter table 72a and the flow rate parameter table 72b as described above. Is defined in advance as the injection time, the waiting time, or the number of pulses per unit time (see FIGS. 8 and 9). The CPU 71 calculates the injection time or waiting time or the driving force (number of pulses) corresponding to the thickness t and the length L set by the thickness setting switch 70 and the flow rate setting dial 80. The injection pump driving circuit 83 reads from the 72a and 72b, and instructs the injection pump driving circuit 83, while the injection pump driving circuit 83 controls the injection pump 83a based on the indicated time and the driving force (number of pulses).

As a result, for example, the watering time or the watering flow rate is changed according to the length L and the thickness t of the sheet material S, or the thickness t is the same, and the watering flow rate is made according to the length L. Since the water can be properly sprayed on the sheet material S without excessive deficiency, the wet towel M can be produced in an appropriate moisture state regardless of the thickness t or the length L of the sheet material S. .

In addition, when the thickness t of the sheet material S is thick or the length L is long, the sprinkling flow rate is increased while the thickness t of the sheet material S is thin or the length L is increased. In the shorter case, the flow rate of the sheet material S can be reduced without causing excessive watering and watering shortage even if the conveyance speed of the sheet material S is reduced, so that the roll can shorten the manufacturing time of the water towel M. Can be.

In addition, since the number of pulses defined in the flow rate parameter table 72b is proportional to the number of revolutions per unit time of the drive motor incorporated in the injection pump 83a, the larger the number of pulses, the larger the driving force of the injection pump 83a is, The pressure is increased and the amount of watering flow per unit time to the sheet material (S) is increased.

The heater driving circuit 84 is a circuit for driving control of the heater 84a according to the instruction of the CPU 71, and the heater 84a has a storage chamber as a storage means, and the water stored in the storage chamber has a predetermined temperature. It is a so-called heater that is heated by heating to maintain a predetermined temperature. By driving the heater 84a (see FIG. 3), hot water is sprayed (sprayed) onto the sheet material S, whereby a warm rolled towel M is produced.

In addition, although the wet towel manufacturing apparatus 1 of this embodiment is a structure provided only with the heater 84a as a heating means of water, it is not necessarily limited to this, Instead of the heater 84a or cooling in addition to the heater 84a, It is naturally possible to comprise the means. As the means for cooling water, various well-known techniques can be applied. For example, a Peltier element (electron refrigeration element) can be used. Thereby, cold water is sprayed (sprayed) on the sheet | seat material S, and a cold rolled paper towel M can be manufactured.

The conveying motor driving circuit 85 is a circuit for driving control of the conveying motor 85a according to the instruction of the CPU 71, and the conveying motor 85a is for supplying rotational force to the conveying belt 51 (see Fig. 3). It is a motor. By driving the conveying motor 85a, one sheet member S cut into the length of the predetermined dimension by the above-described rotary knife 32 is conveyed by the conveyance belt 51 to the downstream side.

As shown in FIG. 3, the guide groove 13 extends upward in the support groove 12 toward the upper side. The guide groove 13 guides the roll rotation guide Ra inserted in the center of the towel roll R from the opening of the main body 2 to the support groove 12, and at the same time, the roll rotation guide Ra It is for restricting the movement of the sheet member S in the drawing direction (right direction in Fig. 3), and includes first and second sidewall members 13a and 13b which are placed in opposite directions with a predetermined gap therebetween.

Therefore, when the towel roll R is replaced, the roll rotation guide Ra can be guided by a guide path formed between the first and second side wall members 13a and 13b of the guide groove 13, so Desorption of the grooves 12 can be facilitated to facilitate the installation and removal of the towel roll R.

In addition, the guide groove 13 or the first and second side wall members 13a, 13b is formed at the same height as the upper end of the upper end of the storage chamber 11, that is, the opening of the main body 2, and at the same time (Fig. 1), as shown in FIG. 3, the width | variety of the guide path of the upper end part becomes wider by taper shape. Therefore, for example, even when the upper cover 3 cannot be fully opened and the guide groove 13 cannot be recognized, the roll rotation guide Ra can be easily inserted into the guide groove 13. Positioning to the guide groove 13 can be made easy, and the installation work of the towel roll R can be made smooth.

In addition, since the placing direction of the second side wall member 13b becomes substantially vertical from the support groove 12 toward the upper side (upper side in FIG. 3) as shown in FIG. 3, when the sheet member S reaches the end, A predetermined crossing angle between the sheet member S and the direction in which the roll rotation guide Ra is drawn (the upper direction inclined rightward toward the driving roller 23 from the support groove 12 in FIG. 3). Can be formed. As a result, since the movement of the roll rotation guide Ra can be reliably regulated only by the said crossing angle, when the sheet | seat material S of the towel roll R reaches | attains the tip, it is attached to the said 2nd side wall member 13b. By the regulating action, the rotational resistance of the drive roller 23 can be increased, so that a current (overcurrent) of a predetermined value or more can reliably flow to the supply motor 81a (see FIG. 2).

In addition, the second side wall member 13b does not necessarily have to be vertically vertically upward as shown in FIG. 3, and is, for example, in a substantially "ku" shape (or inverted "ku" shape) when viewed from the side. It may be bent and comprised. In this way, the movement of the roll rotation guide Ra can be regulated more reliably by the inclined portion or the bent portion of the second side wall member 13b. Alternatively, the locking projection may protrude in the direction of the first sidewall member 13a on the surface of the second sidewall member 13b. Also in this case, the roll rotation guide Ra can be latched and the movement can be regulated reliably.

The supply means 20 pulls out the sheet material S from the towel roll R supported by the roll supporting means 10 to rotate freely, and the cutting means 30 which describes the drawn sheet material S later. And a watering unit 42, the cover member 22, the driving roller 23, the auxiliary roller 24, etc. are mainly provided as shown in FIG.

The cover member 22 is a member for guiding the sheet material S drawn out from the towel roll R in a predetermined direction by a driving roller 23 or the like, which will be described later. The left side is formed substantially horizontally, while the downstream side (right side in FIG. 3) is formed curved in an arc shape along the outer circumference of the driving roller 23. The space between the cover member 22 and the drive roller 23 serves as a conveyance path of the sheet material S. FIG. The sheet material S is guided downward by passing through this conveyance path and fed to the cutting means 30 and the watering part 42 which will be described later.

In addition, a plurality of ribs extending in the feeding direction are formed on the curved surface of the cover member 22 forming the conveying path. Since the ribs can reduce the frictional resistance with the sheet material S, the sheet material S can be stably fed.

The driving roller 23 and the auxiliary roller 24 take out the sheet material S from the towel roll R, and at the same time, cutting means 30 which will be described later through the above-mentioned conveying path. ) And the watering portion 42, which is disposed so as to be able to sandwich the sheet member S as shown in FIG.

The drive roller 23 is a rotating member driven by the feeding motor 81a (refer to FIG. 2), and is provided with a rubber ring cast on its outer circumferential surface. In addition, the rubber ring is provided with a plurality of pieces (four in this embodiment) with a predetermined gap in the width direction of the sheet material S (vertical direction of the sheet in Fig. 3). On the other hand, the auxiliary roller 24 is composed of one substantially rod-shaped body made of metal material such as stainless, and both ends thereof are axially rotatable by the cover member 22.

Here, the cover member 22 is axially rotatable to the main body 2 through the shaft 22a, and is supported by the torsion spring (not shown) in the direction of the driving roller 23 (counterclockwise in FIG. 3). . Therefore, the auxiliary roller 24 can be pressed toward the driving roller 23 by the holding force of the torsion spring so that the sheet material S can be pressed against the driving roller 23, so that the sheet material S is not slipped. It can be reliably conveyed.

In addition, even when the sheet material S of the towel roll R reaches the end and the drawing resistance of the sheet material S is increased, the sliding of the drive roller 23 with respect to the sheet material S can be prevented. Therefore, the overload current can be reliably generated in the feed motor 81a (see FIG. 2) by increasing the rotational resistance of the drive roller 23. As a result, it is detected reliably that the sheet | seat material S of the towel roll R reached the edge.

In addition, the holding force of the torsion spring holding the cover member 22 toward the driving roller 23 side is preferably about 50 to 250 g, and is set to about 150 g in this embodiment. This is because when the holding force is not about 50 g, the sheet material S cannot be sufficiently pushed on the driving roller 23, and the driving roller 23 may slip against the sheet material S. In addition, when it exceeds about 250g, since the rotational resistance of the drive roller 23 becomes large and an excessive load acts on the supply motor 81a, there exists a possibility that an overcurrent may be misdetected.

The cutting means 30 is an apparatus for cutting the sheet material S directly lowered from the supply means 20 to the lower side (lower side in FIG. 3) to a length of a predetermined dimension, and includes a fixed knife 31 and a rotary knife ( 32). The fixed knife 31 is oriented in the width direction of the sheet material S (the vertical direction of the paper surface in FIG. 3), and the rotary knife is disposed at an opposite position with the fixed knife 31 and the sheet material S interposed therebetween. 32 is rotatably rotatable. The rotary knife 32 is connected to the cutting motor 82a (refer to FIG. 2) through a connecting gear (not shown), and the rotary knife 32 rotates counterclockwise while the cutting motor 82a rotates at a predetermined timing. The sheet | seat material S rotated in the (left rotation direction of FIG. 3) and sandwiched between the fixed knife 31 is cut | disconnected by the length of a predetermined dimension from a front-end | tip part.

The watering means 40 is for imparting moisture to the sheet material S, and is mainly provided with a tank storage chamber 41, an injection pump 83a, a heater 84a, a watering part 42, and the like. The tank storage chamber 41 is a member for accommodating the water tank T so that the water tank T can be freely attached and detached, and is disposed on the rear side (right side in FIG. 3) of the main body 2 rather than the supply means 20. The water tank T is accommodated in the tank storage chamber 41 in an inverted state, and the water supply port T _m communicates with the injection pump 83a through the pump absorption tube.

Here, since the water tank T is disposed on the back side (right side of FIG. 3) of the main body 2 rather than the supply means 20 and the watering | pouring part 42 mentioned later, from the towel roll R as shown in FIG. Even when the sheet member S is drawn out by the supply means 20, the water tank T can be replaced as it is. Therefore, even when only the water tank T is replaced due to a mismatch in the exchange time between the water tank T and the towel roll R, the supply means (not shown) to detach the water tank T from the inside of the main body 2 ( 20), the complicated work of rolling up the sheet material S once drawn out is unnecessary.

The discharge port of the injection pump 83a is connected to the heater 84a and the sprinkling part 42 through the water supply hose 43 as shown in FIG. As described above, the heater 84a is configured to be capable of supporting (storing) a predetermined amount of water in the internal storage chamber. The heater 84a is heated to control the water in the storage chamber by maintaining a predetermined temperature by turning on a heater switch (not shown). The hot water heated in the heater 84a is sprinkled from the sprinkling section 42 to the sheet material S.

In addition, although the water supply hose 43 is omitted in FIG. 3, since the top part is pulled so as to pass through a position higher than the injection pump 83a and the nozzle part 42c, the water in the flow path is discharged to the nozzle part 42c and the heater. It can be discharged by flowing down to (84a) side. Therefore, since water can be prevented from being stored in the flow path, for example, when a warm scroll sprinkles hot water with the sheet material S to manufacture the wet towel M, the water return hose 43 is used during the next production. The cold water is stored in the sheet material (S) is sprinkled with water, and the cold roll can prevent manufacturing defects in which the wet towel is manufactured.

In addition, as described above, the heater 84a may naturally be configured to cool the water using a Peltier element or the like. In addition, although the injection pump 83a was arrange | positioned upstream of the heater 84a in this embodiment, it is naturally possible to arrange | position the injection pump 83a downstream of the heater 84a on the contrary. That is, the pumping force of the injection pump 83a acts as a suction force to the heater 84a, and the water drawn up from the heater 84a is configured to be pumped to the water supply hose 43.

The watering means 42 is disposed on the tip side (right side in FIG. 3) of the cover member 52 which will be described later, and includes a watering roller 42a, a watering body 42b, and a nozzle portion 42c. The sprinkling roller 42a is a rotating body composed of a substantially rod-shaped body of a metal material such as stainless, and is axially rotatable on the bottom surface side (lower side in FIG. 3) of the sprinkling body 42b, and the conveyance belt 51 to be described later. Exposed to contact with the conveying surface of. Therefore, when the conveyance belt 51 is driven and the sheet | seat material S is conveyed on the conveyance belt 51, the sprinkling roller 42a rotates with conveyance of the said sheet | seat material S. FIG. In addition, the longitudinal dimension of the said watering roller 42a becomes substantially the same as the horizontal width (dimension of the paper vertical direction of FIG. 3) of the conveyance belt 51. As shown in FIG.

The sprinkling body 42b is a member for storing water for sprinkling with the sheet material S, and is integrally formed with the cover member 52 described later made of a resin material. The water spray body 42b is formed in a substantially box shape having an inner space, and water ejected from the nozzle portion 42c described later is stored in the inner space.

The watering roller 42a described above is axially rotatable in an opening formed in the bottom surface of the watering body 42b, and a slight gap is provided between the watering roller 42a and the opening of the bottom surface. Therefore, when the spraying roller 42a is rotated by the start of the conveyance belt 51 while the water sprayed from the spray nozzle 42c described later is stored in the inner space of the spraying body 42b, the water stored in the inner space is It flows out from an opening part by the rotation of the sprinkling roller 42a, and is sprinkled with the sheet | seat material S. FIG.

The tip of the nozzle portion 42c is opened in the water spray body 42b, and the water discharged from the injection pump 83a through the water supply hose 43 is ejected and stored into the internal space of the water spray body 42b. Further, the tip end of the nozzle portion 42c is configured such that the tip end face side (lower side in FIG. 3) is closed and the side wall side (the front surface side and the rear side in FIG. 3) is opened, so that the spraying roller 42a is in the longitudinal direction. Water can be ejected to the whole.

When moisture is imparted by the sprinkling part 42, one sheet material S cut | disconnected by the cutting means 30 to the length of a predetermined | prescribed dimension is carried out downstream on the conveyance belt 51 of the shaping | molding means 50 ( It is conveyed toward the left side of FIG. In addition, the water which is not absorbed by the sheet material S sprayed from the water spraying part 42 passes through the conveyance belt 51 or the bottom face of the case 54 (refer FIG. 4) to the water support plate 7 mentioned later. Since it is withdrawn, a roll can prevent contamination, a failure of an electrical component, etc. in the wet towel manufacturing apparatus 1, and the like.

The molding means 50 is a device for winding the sheet material S in a columnar shape (roll shape) to form a rolled towel with a wet towel M. The conveying belt 51, the cover member 52, and the reverse ring 53 are formed. It is mainly provided with.

The rolled paper towel manufacturing apparatus 1 of this embodiment is comprised so that a rolled paper towel M may be shape | molded only on one side (upper side of FIG. 3) of the conveyance belt 51. FIG. Therefore, as described above, even when the sheet member S is taken out to the back side of the main body 2 by disposing the towel roll R on the front panel 2b side of the main body 2, The roll towel can be discharged from the front panel 2b side of the main body 2 where the operation panel 4 is disposed, without complicating the molding process path. As a result, the roll can be miniaturized in the wet towel manufacturing apparatus 1. The user can provide a rolled towel manufacturing apparatus 1 that is convenient for the user to use.

The conveying belt 51 is a rubber flat belt having a plurality of protrusions (not shown) all over the outer circumferential surface, and is provided between a pair of rotating rollers 51a rotatably axially supported on the case 54 (see FIG. 4). The cover member 52 is arrange | positioned facing the conveyance surface of the upper side (upper side of FIG. 3) of the said conveyance belt 51. As shown in FIG.

Since the plurality of protrusions 52a protrude in the form of a washboard between the opposite surfaces of the cover member 52 and the conveyance belt 51, a suitable friction force is applied to the sheet member S conveyed by the conveyance belt 51. As a result, a winding core can be reliably caused at the tip of the sheet material S. As a result, the sheet | seat material S can be reliably wound in roll shape centering on the said nucleus, and molding defect can be suppressed.

On the downstream side (left side of FIG. 3) of the cover member 52, the inclined member 52b is inclined so that it may rise in the conveyance direction (left direction of FIG. 3) of the sheet | seat material S. As shown in FIG. The inclined member 52b is a member for supporting the sheet material S during roll forming. The inclined member 52b has a predetermined interval in the width direction (vertical direction of the paper in Fig. 3) of the conveying belt 51 (6 in this embodiment). Dog) is excreted in a roughly comb shape.

In addition, on the lower surface side (lower side in FIG. 3) of each inclined member 52, protrusions having a washboard shape are protruded similarly to the cover member 52. A part of the plurality of inclined members 52b (two in this embodiment) is spoken to a position where the tip (left side in FIG. 3) can contact the rotating roller 53a of the inversion ring 53 described later. When the rotating roller 53a is moved upward, it is comprised so that the movement to the upper side may be suppressed.

A plurality of (five in this embodiment) inversion rings 53 are disposed between the adjacent portions of these conveyance belts 51, respectively. The inversion ring 53 is installed between the pair of rotary rollers 53a rotatably supported by the case 54 (see FIG. 4) as a rubber ring, and at the same time, the sheet material S is jointly with the conveying belt 51. It is arrange | positioned facing the conveyance belt 51 so that it may wind up in roll shape.

Here, both ends of the rotating roller 53a located on the conveying direction side (left side of FIG. 3) of the sheet material S in the pair of rotating rollers 53a are vertical grooves 54a formed up and down in the case 54. While rotatable in, the carrier belt 51 is inserted to enable movement toward the side (lower side of FIG. 3) or the opposite side (upper side of FIG. 3) of the transport belt 51. Therefore, when the sheet member S is wound in a roll shape, the reversal ring 53 can be moved up and down with the increase in the roll diameter, so that the roll towel is rolled regardless of the thickness of the sheet member S and the sheet length. Molding of (M) can be made smooth.

On one side of the rotating roller 51a on which the conveying belt 51 is installed, a conveying motor 85a (see FIG. 2) is connected through a plurality of gears, and when the conveying motor 85a is driven to rotate, the conveying belt 51 Rotate in the counterclockwise direction (left-turn direction in FIG. 3). Then, the inversion motor 86a (see FIG. 2) is connected to one side of the rotating roller 53a on which the inversion ring 53 is hypothesized. When the inversion motor 86a is driven to rotate, the inversion ring ( 53) rotates clockwise (the right-turn direction in FIG. 3), that is, in the opposite direction to the conveyance belt 51. In addition, the reduction ratio of each coupling gear and the output characteristics of each motor 85a, 86a are set so that the absolute conveyance speeds of the opposing surfaces of the conveyance belt 51 and the inversion ring 53 may become substantially the same.

The sheet member S, which has passed through the above-mentioned sprinkling part 42 and is directly lowered to the conveying direction upstream side (right side in FIG. 3) of the conveying belt 51, is rotated in the downstream direction by the conveyance belt 51 (FIG. 3). Leftward). As a result, the sheet member S is caused to be wound up at its distal end between the opposing surfaces of the cover member 52 and supported to the lower surface side of the inclined member 52b between the opposing surfaces of the inversion ring 53. , And wound in a roll shape around the caused nucleus to form a cylindrical roll into a wet towel (M).

In addition, the opposing surfaces of the inversion ring 53 and the conveyance belt 51 are moved at substantially the same speed in opposite directions as described above. Therefore, since the relative speed difference of both opposing surfaces can be enlarged, the winding speed of the sheet | seat material S can be made high, and the roll can shorten the shaping | molding time of the wet towel M by that much.

When the roll is finished forming the wet towel M, the rotation of the inversion ring 53 is stopped, so that the roll wet towel M is conveyed to the downstream side (left side in FIG. 3) by the rotation of the conveyance belt 51 to be described later. The saucer is released onto the combined lid (5).

Further, on the downstream side of the conveyance belt 51, as shown in FIG. 3, a vertical band 59 is attached to the case 54 (see FIG. 4). This vertical band 59 is a member for preventing the roll of the towel M from collapsing during conveyance. The vertical band 59 is made of a flexible rubber material and has a sheet shape having a width substantially equal to that of the conveying belt 51. Therefore, since the roll towel conveyed on the conveying belt 51 is conveyed to the downstream side while the outer circumferential surface is rubbed with the vertical band 59, the roll conveys the wet towel M without rolling, and the scroll rolls of the wet towel M Can be suppressed.

In addition, since the roll towel (M) is wound right around the core of the roll (clockwise in FIG. 3), it is rubbed in the winding direction by the vertical band 59 so that the end of the roll is not loosened. Further, the base (upper side in FIG. 3) of the vertical band 59 is axially rotatable in the case 54 (see FIG. 4), and the scroll is configured to be movable up and down in accordance with the conveyance of the towel M. FIG. In the vertical band 59, a plurality of protrusions protrude from the side surface (right side of FIG. 3) facing the conveyance belt 51, so that the scroll has a large contact resistance to the towel.

As shown in FIG. 3, the support plate combined lid 5 is provided on the front panel 2b side (left side of FIG. 3) of the main body 2 which is the downstream end (left side of FIG. 3) of the conveyance belt 51 of the shaping | molding means 50. As shown in FIG. ) Is excreted and drip tray 7 is excreted below.

As described above, the support plate combined lid 5 is used as a support plate on which a plurality of rolls are placed on the wet towel M when it is opened, and when closed, the lid is used as a lid to close the front side of the main body 2 on its surface side. (See Figure 1). In addition, the drip tray 7 is a container for recovering the water sprinkled from the nozzle portion 42c of the sprinkling portion 42, and is attached to and detached from the opening 2b1 opened in the front panel 2b of the main body 2. It is configured to be possible.

Further, a flow rate setting dial 60 for setting the watering flow rate per unit time from the nozzle portion 42c is provided on the front side of the main body 2 (see FIG. 6A). The flow rate setting dial 60 outputs a different resistance value according to its stop position, and is composed of a rotary switch capable of rotating operation in the forward or reverse direction from the lower limit Min to the upper limit Max.

Further, on the surface 2b1 of the front panel 2a, a thickness conversion switch 70 for converting the thickness of the sheet material S (refer to FIGS. 8 and 9) and the length of the sheet material S ( L: see FIG. 8 and FIG. 9, respectively, for setting the length setting dials 80 (see FIG. 6B). The thickness conversion switch 70 is a two-value conversion type flexible switch, and is configured to set the thickness t of the sheet material S to one of "thick" and "thin". On the other hand, the length setting dial 80 is a rotary switch of a six-value conversion type, and is configured to be able to set the length L of the sheet material S in 6 cm ranges in the range of "18 to 48 cm". In addition, the cutting means 30 described above is to cut the sheet material (S) by the length (L) set here.

Next, with reference to FIG. 4 and FIG. 5, the detailed structure of the support plate combined lid 5 and the support plate 7 is demonstrated. 4 and 5 are partially enlarged cross-sectional views of the rolled towel manufacturing apparatus 1, respectively showing the closed state and the open state of the support plate combined lid 5, respectively.

The support plate combined use lid 5 has a mounting surface 5a on which a roll towel M is placed, and a rear end wall 5b entered from the rear end side (lower side of FIG. 4, left side of FIG. 5) of the mounting surface 5a. ) And a pair of side wall portions 5c which face each other and face each other on both side portions of the placing surface 5a and the rear end wall 5b (the back side and the front side of the ground in FIGS. 4 and 5). The upper side (left side of FIG. 4, upper side of FIG. 5) is opened from each of these members, and a plurality of scrolls are configured in a container shape capable of supporting the wet towel M (see FIG. 11).

As shown in FIGS. 4 and 5, the mounting surface 5a is inclined while both sides of the front-back direction (left-right direction of FIG. 5) are raised, and is comprised in substantially 凹 shape from the side cross section shown in FIG. The restricting plate 5a1 is placed in the substantially center portion in the front-rear direction of the placing surface 5a. The regulating plate 5a1 is a member for aligning the rolls discharged from the conveyance belt 51 onto the mounting surface 5a by regulating the movement of the wet towel M, and between the rear end walls 5b to be described later. The scroll is formed so as to extend in the direction (perpendicular to the surface of Fig. 4 and Fig. 5) substantially perpendicular to the discharge direction of the wet towel M, while leaving a gap of more than the diameter of the wet towel M (see Fig. 11).

The upper end part (left side of FIG. 4, upper side of FIG. 5) of the rear end wall 5b is a member for which the roll conveyed by the conveyance belt 51 jumps the wet towel M toward the conveyance surface, as shown in FIG. When the saucer combined lid 5 is opened, it is configured to be adjacent to the downstream end (right side of FIGS. 4 and 5) of the conveyance belt 51. Therefore, when the scroll is conveyed from the conveyance belt 51, the scroll can turn over the wet towel M by contacting the upper end of the rear end wall 5b, so that the scroll mounts the wet towel M (5a). You can jump farther away from).

Moreover, the upper end part of this rear end wall 5b is formed in one step of substantially step shape which descend | falls toward the mounting surface 5a. That is, since the upper end portion 5b1 disposed on the conveyance belt 51 side and the lower end portion 5b2 disposed on the mounting surface 5a side are formed on the stepped portion, the scroll rolls the wet towel M and the upper end portion 5b1. Since the lower end portion 5b2 can be in contact with each other in turn, the roll can be made to jump toward the mounting surface 5a without disturbing the shape of the wet towel M. FIG.

In addition, as described above, according to the roll towel manufacturing apparatus 1 of the present embodiment, the upper end of the rear end wall 5b is adjacent to the downstream end of the conveying belt 51 in the state in which the support plate combined lid 5 is opened. Since it is comprised, a roll can discharge | release a wet towel M directly from the conveyance belt 51 to the mounting surface 5a of the support plate combined use lid 5. Therefore, the conventional rolls do not need to convey the towels to the support plate combined lid 5 while the guide plate is laid between the conveying belt 51 and the support plate combined lid 5 like the wet towel manufacturing apparatus and rolled on the guide plate.

Therefore, by reducing the number of parts as much as the guide plate is unnecessary, the roll can reduce the overall product cost of the wet towel manufacturing apparatus 1, and when the conventional roll is rolled on the guide plate like the wet towel manufacturing apparatus, the scroll of the wet towel (M) Since it can be avoided, the scroll can provide the user with the wet towel M in a well wound state.

Protruding shafts 5c1 protrude from the outer surfaces of the side wall portions 5c (the rear and front sides of the paper in Figs. 4 and 5), and the protruding shafts 5c1 are supported by the supporting plate 8, which will be described later. It is rotatable into the groove 9 and supported to be freely detached. Thus, the support plate combined lid 5 is configured to be opened and closed with the protruding shaft 5c1 as a point as shown in Figs. 4 and 5, and the main body (by removing the protruding shaft 5c1 from the support groove 9). It is configured to be separated from 2).

The support plate 8 is a pair of plate-like members which are disposed to face each other on the outside of both sidewall plates 5c, and support grooves 8 are recessed on both opposing surfaces of these support plates 8. The support groove 8 is a groove having a substantially “co” shape in cross section for supporting the above-described protruding shaft 5c1 so as to be freely rotated and detached, and as shown in FIGS. 4 and 5, the lower end side thereof (FIGS. 4 and 5). While supporting the protruding shaft 5c1 rotatably with a support formed in an arc shape on the lower side of FIG. 5, the protruding shaft 5c1 is formed from an opening formed at an upper end (upper side in FIGS. 4 and 5). Can be removed or inserted.

Moreover, the passage of the support groove 9 which connects the support part at the lower end side and the opening part at the upper end side is bent in a substantially "ku" shape from the front, as shown in FIGS. 4 and 5. For this reason, when the user opens and closes the support plate combined lid 5, the protruding shaft 5c1 of the support plate combined lid 5 is supported even when the support plate combined lid 5 is inadvertently lifted upward. Since the separation from the opening of the groove 9 can be suppressed, it is possible to suppress the support plate 5 from being pulled out of the main body 2 during the opening and closing operation. As a result, it becomes possible to improve the operability of the opening and closing operation of the base plate combined lid 5.

In addition, since the passage path of the support groove 9 faces the back side (right side of FIGS. 4 and 5) of the main body 2, that is, the supporting portion at the lower end side of the back side of the main body 2 rather than the opening at the upper end side ( Since it is formed to be bent to the inside), as shown in Figure 5, the open base plate combined lid (5) can be drawn into the inside of the main body (2). Therefore, the open base plate combined lid 5 can reduce the amount of protrusion protruding from the front panel 2b of the main body 2 (the left side of Figs. 4 and 5), so that the base plate combined lid 5 It becomes an obstacle, and it is possible to suppress that the place where the scroll is placed in the wet towel manufacturing apparatus 1 is limited or that the roll is damaged by the appearance of the wet towel manufacturing apparatus 1.

In addition, since the support groove 9 is configured to be bent in this manner, when the support plate combined lid 5 is removed, the support plate combined lid 5 is disposed on the front side of the main body 2 (FIGS. 4 and 5). It can be removed by lifting upward while moving to the left). That is, since the support plate combined lid 5 does not need to be moved to the inside of the main body 2 (the right side of FIGS. 4 and 5), the members of the support plate combined lid 5 and the main body 2 (eg For example, it is not necessary to consider the interference with the conveyance belt 51, etc., and there is no need to provide a vacant space for avoiding the interference, so that the roll can reduce the overall size of the wet towel manufacturing apparatus 1.

The photosensor 120 is arrange | positioned at the side wall of the opening part 2b1 of the main body 2 as shown to FIG. 4 and FIG. The optical sensor 120 is a sensor for detecting the open / closed state of the support plate 5 by the change in the amount of reflection of the irradiated light, a light emitting element 120a as a light source for irradiating infrared rays, and a light receiving element for receiving the reflected light It is comprised with 120b. The light irradiation surface of the light emitting element 120a and the light receiving surface of the light receiving element 120b are opened with each other so as to be opposite to the side wall portion 5c of the support plate 5 as shown in FIGS. 4 and 5. It is excreted on the same side wall of 2b1).

In addition, in the optical sensor 120 of the present embodiment, the light emitting device 120a is configured by an infrared LED, and the light receiving device 120b is configured by a photo transistor. However, irradiated light is not limited to infrared rays, but of course, it is also possible to configure so as to irradiate (receive) light having other wavelengths.

When the infrared light emitted from the light-emitting element 120a and reflected from the side wall portion 5c or the opposite side wall of the base plate combined lid 5 as an object is received by the light-receiving element 120b, the amount of received light is controlled by the sensor control circuit 89: A / D is converted into digital values by the CPU 71 (see FIG. 2). The CPU 71 determines the opening / closing state of the base plate combined lid 5 according to whether the read value is equal to or greater than a predetermined threshold value.

In detail, when the support plate combined lid 5 is closed, since the side wall portion 5c of the support plate combined lid 5 is disposed in front of the light emitting element 120a as shown in FIG. The infrared light irradiated from the element 120a is directly reflected by the side wall portion 5c of the lid 5, and the amount of light received by the light receiving element 120b becomes a large value (threshold or higher). On the other hand, when the support plate combined lid 5 is opened, as shown in FIG. 5, there is no obstacle in front of the light emitting element 120a, and the infrared light irradiated from the light emitting element 120a is the opening 2b1. Reflected from the side wall opposite to the side wall), the light-receiving amount received by the light-receiving element 120b becomes a small value (below the threshold value). As a result, it is possible to detect the open / closed state of the support plate lid 5 according to the amount of light received by the light receiving element 120b.

In addition, the rolled-up wet towel manufacturing apparatus 1 of this embodiment has the edge of the side edge part 5c of the base plate lid 5 with the optical sensor 120 open as shown in FIG. 5 (upper end of FIG. 5). Periphery), so that when the base plate combined lid 5 is not completely closed, as shown in FIG. 4, that is, even half open, the optical base plate 5 is opened. 120 does not detect it. That is, the rolled towel towel manufacturing apparatus 1 of the present embodiment has the optical sensor 120 that the support plate 5 is open when the support plate 5 is fully open as shown in FIG. Can be detected.

If the support plate 5 is detected by the optical sensor 120 as the support plate 5 is closed, the CPU 71 (see Fig. 2) invalidates the pressing of the run / stop button 4a as described above, and the rolled towel M is rolled. Prohibit the manufacture of Therefore, for example, even if the user presses the operation / stop button 4a with the base plate combined lid 5 closed, even if the roll instructs the manufacture of the towel M, the manufacture can be avoided from starting. The wet towel (M) does not reach the roll up to the support plate (2), and the clogging of the wet towel (M) occurs in the main body (2), that is, the forming means (50), or is conveyed due to the blockage. It is possible to avoid manufacturing defects in which the loads of the inverting motors 85a and 86a become excessive and break.

In addition, the rolled towel towel manufacturing apparatus 1 of the present embodiment is configured to block the front of the optical plate 120 when the support plate combined lid 5 when the support plate combined lid 5 is closed as described above (FIG. 4). And FIG. 5), when the support plate combined lid 5 is separated from the main body 2, the detection result similar to the case where the support plate combined lid 5 shown in FIG. 5 is opened is shown by the optical sensor 120. Can be generated.

Therefore, even when the support plate 5 is removed from the main body 2, the roll is not prohibited from the manufacture of the wet towel M, so that the support plate 5 is removed from the support plate so that the prohibition operation does not work. Since it is possible to simplify the configuration without the need of separately providing a detection means for detecting whether or not and a release means for releasing the prohibited operation, the number of parts and the design cost can be reduced, so that the product as a whole wet towel manufacturing apparatus 1 can be manufactured. The cost can be reduced.

In addition, when the side wall portion 5c of the combined lid 5 of the support plate is made of a light color (for example, white), the side wall of the opening 2b1 opposite to the excretion surface of the optical sensor 120 is dark. It is preferable to comprise in color (for example, black), and when the side wall part 5c is comprised in dark color, it is preferable to comprise the side wall of the opening part 2b1 in light color. Thereby, the light quantity difference of the reflected light which changes according to the opening / closing state of the base plate combined lid 5 can be enlarged, and the detection precision of the optical sensor 120 can be improved.

On the lower side of the support plate combined use lid 5, the drip tray 7 is detachably disposed as shown in FIGS. 4 and 5. The drip tray 7 is a container for recovering water which has been sprayed from the above watering portion 42 and is not absorbed by the sheet material S, and has an approximately opened upper surface side (the upper side in FIGS. 4 and 5). It consists of a box shape.

The opening 2b1 is formed in the front panel 2b of the main body 2 as described above, and the drip tray 7 is detachable through the opening 2b1 irrespective of the opening / closing state of the combined lid 5 on the base plate. It is composed. Therefore, the conventional scroll does not need to separate the front panel of the apparatus main body like the wet towel manufacturing apparatus, and the detachment operation of the drip tray 7 is simplified, so that the water stored in the drip tray 7 can be easily disposed. . In addition, guide members (not shown) are disposed on both sides of the water support plate 7 in the horizontal width direction (the paper vertical direction in FIGS. 4 and 5), and the front and rear directions of the water support plate 7 are provided by the guide members. And the left and right directions of FIG. 5 are guided.

A collection member 6 is disposed between the drip tray 7 and the conveyance belt 51 as shown in FIGS. 4 and 5. The collecting member 6 is a member for collecting the water flowing along the bottom surface 54a of the conveyance belt 51 or the case 54 and sending it to the drip tray 7 to collect all the flowing water. In order to be able to do so, a collecting port opened to an upper end (upper side in Figs. 4 and 5) is formed with a width slightly larger than the width of the bottom face 54a (vertical dimension in the plane of Figs. 4 and 5). In addition, the water collected by the collecting member 6 is discharged into the drip tray 7 from the discharge port 6a having a small diameter at the lower end of the collecting member 6.

In this way, since water flowing down from the conveyance belt 51 or the like is collected by the collecting member 6, the transverse width (the vertical dimension of the ground in Figs. 4 and 5) of the drip tray 7 is conveyed by the conveyance belt 51 and the like. It can be configured to be narrower than the width of. Therefore, it is not necessary to configure the width of the drip tray wider than the width of the conveying belt so that the conventional scroll can collect the water flowing down the conveying belt or the like directly like the wet towel manufacturing apparatus. Therefore, since the width of the drip tray 7 can be made smaller, the space for installing the above-described guide member can be secured on both sides of the drip tray 7 in the widthwise direction, and as a result, the rolled towel is manufactured. The width of (1) can be made small.

Here, a lid member 7a covering the top opening of the drip tray 7 is detachably mounted to the top surface side (upper side of FIGS. 4 and 5), and the collection member 6 is attached to the lid member 7a. The opening part 7a1 is installed in the position corresponding to the discharge port 6a of (). Therefore, at the time of separating the drip tray 7, even if the drip tray 7 is shaken or inclined, since the water stored therein can be suppressed by the lid member 7a, Separation work can be done safely and quickly.

In addition, it is preferable that at least one of the drip tray 7 or the lid member 7a is made of a transparent resin material. In the case where the drip tray 7 is made of a transparent resin material, the drip tray 7 is not separated from the main body 2, that is, the opening 2b1 of the main body 2 as it is provided in the main body 2. The amount of water in the drip tray 7 can be visually recognized. On the other hand, when the lid member 7a is made of a transparent resin material, the quantity of the drip tray 7 can be visually recognized without removing the lid member 7a.

Next, a process in which the scroll configured as described above is executed in the wet towel manufacturing apparatus 1 will be described with reference to the flowchart of FIG. 7.

7 is a flowchart showing the main processing executed by the CPU 71. This process is a process in which the scroll is started by turning on the power of the wet towel manufacturing apparatus 1 and repeatedly executed by the CPU 71 while the power is turned on.

In addition, when the detection signal 93 from the overcurrent detection circuit 81b is input to the CPU 71 during the execution of the main processing, the overcurrent detection processing (interrupt processing) (not shown) is immediately executed. In the overcurrent detection process, the drive of the feeding motor 81a is stopped and the user is notified that the sheet material S of the towel roll R has reached the end.

Here, the flowchart of the main processing will be described with reference to Figs. 8 to 10 as appropriate. 8 and 9 are diagrams schematically showing the contents of the time parameter table 72a and the flow rate parameter table 72b stored in the ROM 72, respectively, and FIG. 10 shows the operation state of the watering means 40. FIG. The time chart shown.

The CPU 71 first executes the initial setting processing S1 in the main processing. In the initial setting process, the presence or absence of the towel roll (R) or the sheet material (S), the state of each driving device, the opening / closing state of the supporting plate (5), and the like are displayed. Displayed by the apparatus, and a process of applying a preload driving force to the injection pump 83a of the watering means 40 is performed so that the rolled-up towel manufacturing apparatus 1 is set to a state in which the rolled-up wet towel M can be started. do.

In addition, the preload driving force imparted to the injection pump 83a is to increase the response speed applied to the watering, and the thickness t and the length L of the sheet material S to the preload driving force P _{b of} the flow rate parameter table described above. ), And is defined in connection with (). The CPU 71 reads the preload driving force P _b corresponding to the thickness t and the length L set by the thickness conversion switch 70 and the length setting dial 80 from the flow rate parameter table, and the value thereof. The injection pump 83a is driven in advance.

The provision of the preload driving force P _b to the injection pump 83a is continued until the start-up waiting time T _s described later (see FIG. 10), and according to the passage of the waiting time T _s at the start When watering instruction occurs, watering can be immediately performed from the nozzle part 42c.

Here, the water supply hose 43 is pulled so as to pass through a position higher than the injection pump 83a and the nozzle portion 42c so as to prevent water from remaining in the path as described above, but the preload driving force P The value of _b ) is such that the driving force is such that water pressurized by the injection pump 83a does not reach the top of the water supply hose 43.

For this reason, even when a preload driving force is applied to the injection pump 83a for a predetermined waiting time in order to increase the response speed of watering, the pumped water is not pumped over the top of the water supply hose 43, so that wasteful water is not supplied. Water can be prevented from being sprayed from the nozzle portion 42c and moisture can be applied to the sheet material S efficiently with a small amount of water.

In the process of S2, it is checked whether the operation button 4a is pressed (S2), and if the operation button 4a is not pressed (S2: No), each process S3 is executed. In each processing S3, setting processing by various buttons 92 (refer to FIG. 3) (e.g., the number of rolls of the towel M), display control of the LCD 4b, and the like are executed. After execution of each process S3, it transfers to the process of S2.

If it is confirmed that the operation button 4a is pressed in the process of S2 (S2: Yes), the user has instructed the start of the manufacture of the wet towel M, so that the scroll can start the manufacture of the wet towel M. The process after S4 is executed.

In this case, the CPU 71 first drives the feeding motor 81a and rotates the driving roller 23 (see FIG. 3), thereby starting the drawing out operation of the sheet material S from the towel roll R and carrying the conveying motor. Drive (S4). As a result, the sheet material S is transferred from the supply means 20 toward the sprinkling part 42 and the forming means 50, and preparation of the leading end of the sheet material S into the conveying path of the forming means 50 is performed. All.

After starting the withdrawal operation of the sheet material S (S4), the process shifts to S5 to confirm whether T _s seconds have elapsed from the press of the operation button 4a (S5), and when T _s seconds has elapsed. Wait until (S5: No).

Further, the waiting time (T _s) is built as a wait time (T _s) at the start of the above time parameter table (72a), related to the thickness (t) and the length (L) of the sheet material (S) a plurality of A value is defined (refer to FIG. 8), and the waiting time T _s at the start of each of these is the watering part 42 at the tip of the sheet material S directly below the supply means 20 by the time elapsed by that value. It is set to reach the upstream side of the nozzle part 42c or to pass to the downstream side.

Therefore, when it is determined that T _s seconds have elapsed from the pressing of the operation button 4a in the process of S5 (S5: Yes), the tip of the sheet member S is connected to the nozzle portion 42c of the sprinkling portion 42. Since it reaches to the predetermined position, the injection pump 83a is driven under the first condition to start the injection (spraying) of water from the nozzle portion 42c to the sheet material S (S6).

In addition, the first condition is the inlet when the driving force (P _p) the means and the thickness of the sheet material (S) (t) and the length (L) defined in the above-described flow rate parameter table (72b) in the processing of S6 Associated and defined (see FIG. 9). The CPU 71 calculates the value of the driving force P _p at the time of entry corresponding to the thickness t and the length L set by the thickness conversion switch 70 and the length setting dial 80 from the flow rate parameter table 72b. is read out to drive the jet pump (83a) to the inlet when the driving force _{(p p).} Therefore, since the sheet material S is sprinkled corresponding to the thickness t and the length L, excessive sprinkling and deficiency of sprinkling can be suppressed. As a result, a wet towel M is produced with a roll of moderate moisture.

In addition, the value of the waiting time T _s at the start becomes the longest (200ms) when the length L of the sheet material S is the shortest (L = 18 cm), while the value of the preload driving force P _b is When the length L of the sheet material S is the shortest, it becomes largest (180 pulses / s) (refer FIG. 8 and FIG. 9). As a result, by delaying the watering timing to the tip portion of the sheet material S drawn into the forming means 50, the tip portion is prevented from being excessively sprinkled, and the molding failure in the molding means 50 caused by the excessive sprinkling is prevented. Occurrence can be suppressed.

In addition, when the spraying timing is delayed, the spraying timing may be too late due to an error caused by various conditions, and the tip end portion of the sheet material S may be sprayed less than the target value. In this case, the preload driving force P _b By increasing the response speed, the shortage of water can be reliably suppressed.

In addition, since the minimum value data of the driving force P _p at the time of drawing is a value which is not sprayed from the water spray nozzle 42c, ie, a value smaller than the value of the preload driving force P _b , for example, the flow regulating dial 60 has a lower limit value. (Min) is set (see Fig. 6A), when the roll with the smallest moisture is instructed by the user to manufacture the wet towel M, the watering to the front end of the sheet member S introduced into the forming means 50 is carried out. By not doing so, a scroll having a smaller moisture state can reliably produce a wet towel (M).

In this way, the use of the watering operation is waited only for a predetermined waiting time until the predetermined timing arrives, so that the use of water can be suppressed. As a result, the water can be sprayed on the sheet material S efficiently with a small amount of water, and it is not only economical but also can reduce the frequency of exchange of the water tank T and the saucer 7 to reduce the burden on the user.

After starting the water spraying operation to the sheet material S (S6), the process proceeds to S8 to check whether the drawing of the sheet material S is completed into the conveying path of the forming means 50 (S8), It waits until the drawing process is completed (S8: No). In addition, in the wet towel manufacturing apparatus 1 of this embodiment, the rotation speed of the driving roller 23 is detected by a rotation sensor, and when the rotation speed reaches a predetermined number of times, the sheet material S is set to complete the drawing-in process. .

That is, in the roll towel manufacturing apparatus 1 of the present embodiment, as described above, the length of the sheet material S can be set to a value of 6 cm interval in the range of 18 cm to 48 mm by the length setting dial 80 (see FIG. 6B). Since it is comprised, the drive roller 23 is rotated only by the rotation speed corresponding to each set length.

Therefore, when it is determined that the driving roller 23 has been rotated only a predetermined number of times, since the drawing processing of the sheet material S has been completed by the length set by the user (S8: Yes), the feed motor 81a and the injection pump ( 83a) and the driving motor 85a are stopped (S9), the drawing work of the sheet material S from the towel roll R, the watering operation of the sheet material S, and the tip of the sheet material S The draw-in operation to the shaping | molding means 50 is complete | finished respectively.

Thereby, the sheet | seat material S is supported on the conveyance path | route from the supply means 20 to the shaping | molding means 50 (refer FIG. 3). In addition, when the length of the sheet material S set by the length setting dial 80 is short (for example, 18 cm), the tip of the sheet material S is stopped near the inlet of the forming means 50. When the length of the sheet material S set by the length setting dial 80 is long (for example, 48 cm), the sheet material S is in the conveying path of the forming means 50 (cover member 22). Back to the opposite side, causing a winding core to the tip.

After the drawing process of the sheet material S is finished (S8: Yes, S9), the sheet material S is fixed to the fixed knife 33 by driving the cutting motor 82a to rotate the rotary knife 32. Cut together (S10). Then, the driving of the cutting motor 82a is restarted and the conveyance belt 51 is rotated to convey the sheet material S along the conveying path of the forming means 50, and the inverting motor 86a is driven to invert the ring. By rotating the 53, the sheet member S is wound into a roll shape, and the roll starts forming the wet towel M (S11).

In addition, the inversion ring 53 is moved in the opposite direction to the conveyance belt 51, the movement speed of the inversion ring 53 is substantially the same as the movement speed of the conveyance belt 51. In addition, after cutting the sheet material S, a preload driving force P _b is applied to the injection pump 83a so as to increase the response speed of watering until the waiting time T _c at the time of cutting, which will be described later, elapses. Wait in the state (see FIG. 10).

After the roll starts forming the wet towel M (S11), the process shifts to S12 to check whether T _c seconds have elapsed from the start of driving the cutting motor 82a (S12), and when T _c seconds has elapsed. Wait until (S12: No). The waiting time (T _c) is a cutting standby time (T _c) as, related built plurality of values and the thickness (t) and the length (L) of the sheet material (S) of the above-described time parameter table (72a) (See FIG. 8), by waiting for the spraying operation in order to avoid the manufacturing failure due to excessive spraying, so that the shorter the length (L) of the sheet material (S) to a larger value (that is, the longer the waiting time) Is prescribed.

Therefore, in the process of S12, if it is determined that T _c seconds have elapsed since the start of the drive of the cutting motor 82a (S12: Yes), the waiting for the watering operation is finished, and thus the injection pump 83a is subjected to the second condition. Is started to start spraying (spraying) water from the nozzle portion 42c to the sheet material S (S13).

Further, the second condition when specified in the above-described flow rate parameter table (72b) cutting force (P _c) the means and the thickness of the sheet material (S) (t) and the length (L) in the process of S13 Associated and defined (see FIG. 9). The CPU 71 calculates the value of the driving force P _c at the time of cutting corresponding to the thickness t and the length L set by the thickness conversion switch 70 and the length setting dial 80 from the flow rate parameter table 72b. It reads out and drives the injection pump 83a with the driving force P _c at the time of the cutting | disconnection. Accordingly, since the sheet material S is sprayed corresponding to the thickness t and the length L, excessive spraying and lack of spraying can be suppressed, and as a result, a rolled towel M having moderate moisture is produced. do.

For example, when the thickness t of the sheet material S is thick, the driving force of the injection pump 83a is increased and the watering flow rate is increased, while when the thickness t of the sheet material S is thin, the injection is performed. By reducing the driving force of the pump 83a and reducing the watering flow rate (see FIG. 9), even if the conveying speed of the sheet material S is increased, the water can be conveyed without causing excessive watering and lack of watering. The shortening of the manufacturing time of (M) can be achieved.

In addition, the value of the driving force P _c at the time of cutting becomes the largest (255-295 pulses / s) when the length of the sheet | seat material S is shortest (L = 18cm) (refer FIG. 9). Therefore, as described above, the value of the waiting time T _s at the start of the case where the length L of the sheet material S is the shortest (L = 18 cm) is longest so as to suppress the molding failure caused by the excessive spraying. (200 ms) Even if the spraying timing to the tip portion of the sheet material S is delayed (see FIG. 8), the roll material having appropriate moisture can be produced to avoid the entire sheet material S from lack of watering. Can be.

In this way, it is possible to suppress the use of sprinkling of unnecessary water by waiting for the sprinkling operation for a predetermined waiting time until the predetermined timing arrives. As a result, it is possible to spray the sheet material S efficiently with a small amount of water, which is not only economical, but also reduces the frequency of exchange of the water tank T and the drip tray 7 to reduce the burden on the user.

After starting the water spraying operation on the sheet material S (S13), the process shifts to S14 to check whether or not T _m seconds have elapsed since the start of the driving of the injection pump 83a (S8), and T _m seconds has elapsed. Wait until it is done (S14: No). This waiting time T _m is the operation time T _m at the time of cutting in the above-described time parameter table 72a, which is related to the thickness t and the length L of the sheet material S, and a plurality of values are defined. (See FIG. 8), the length L of the sheet material S is set to be as large as the length (that is, the spraying time becomes longer) so as to avoid the lack of watering to the rear end of the sheet material S. do.

Therefore, when it is judged that T _m seconds have elapsed from the start of driving of the injection pump 83a in the process of S15 (S14: Yes), since the spraying operation is completed to the rear end of the sheet material S, the injection pump 83a is completed. ) Is stopped and water injection (spraying) from the nozzle portion 42c to the sheet material S is terminated (S15).

In addition, after the spraying time to the sheet material S, i.e., the operating time T _m at the time of cutting, the spray pump may be used to increase the response speed of the spraying when the roll is continuously manufactured again. 83a) gives a preload drive force P _b , while the scroll finishes the manufacture of the wet towel M (e.g., only one is produced, or the current one is the last to be manufactured continuously). ), No preload driving force is applied to the injection pump 83a in order to suppress wasteful power consumption (see FIG. 10).

In the process of S16, the scroll executed by the shaping means 50 checks whether or not the shaping of the wet towel M is completed (S16), and waits until the shaping process is completed (S16: No). Here, a description will be given of an aspect in which the roll towel M is molded by the forming means 50 in the roll towel wipe apparatus 1 of the present embodiment. When the forming of the wet wipes M is started in the processing of S11, the sheet material S is first conveyed in the downstream direction (left direction in FIG. 3) by the rotation of the conveyance belt 51 to cover the cover member. Passing between opposing surfaces with 52 causes a winding nucleus at its distal end, and is then conveyed again to reach between opposing surfaces with inversion ring 53.

Opposing surfaces of the inversion ring 53 and the conveyance belt 51 are moved at substantially the same speed in opposite directions to each other. For this reason, the sheet | seat material S which reached between the said opposing surfaces is wound up in roll shape, being supported by the lower surface side of the inclination member 52b centering on the caused nucleus. As a result, the belt lengths of the inversion ring 53 and the conveyance belt 51 are not required to secure the length (belt length) of the processing path for winding the sheet material S into a roll like the conventional roll towel manufacturing apparatus. Since the molding unit 50 can be shortened, the molding means 50 can be downsized, so that the entire rolled towel manufacturing apparatus 1 can be downsized.

In addition, since the relative speed difference of the opposing surface can be maximized by making the moving speeds of the inversion ring 53 and the conveyance belt 51 substantially the same, the winding speed of the sheet | seat material S is speeded up and that much rolled up. The molding time of the wet towel M can be shortened.

In addition, even when the moving speed of the inversion ring 53 becomes higher than the moving speed of the conveyance belt 51 due to, for example, dimensional error or assembly error in manufacturing, or an error in motor output characteristics, the inclined member ( 52b) is formed to be inclined while rising in the conveying direction (left direction in FIG. 3) of the sheet material S, so that the sheet material S flows back to the conveying direction upstream (right direction in FIG. 3) during roll forming. You can prevent it from being thrown away. Therefore, it is not necessary to exactly match the moving speeds of the conveying belt 51 and the reversing ring 53, so that manufacturing costs such as administrative expenses can be reduced by suppressing the required level of dimensional or assembly errors. .

When the roll forming of the sheet member S proceeds, the sheet member S is limited to the inclination of the inclined member 52b in accordance with the increase in the roll diameter, so that the next conveying direction is at the lower surface side of the inclined member 52b. It moves to the downstream side (left direction of FIG. 3). In this case, one roller 53a (left side in FIG. 3) winding the reversing ring 53 will run upward (upper side in FIG. 3) along the longitudinal groove 54a with the increase in the roll diameter as described above. It becomes possible.

Therefore, regardless of the thickness or length of the sheet material S, it can be wound in a roll shape, so even if the thickness or length of the sheet material S is changed, a rolled towel is rolled in various roll diameters from a small diameter to a large diameter ( M) can be manufactured reliably. Moreover, since the contact state of the sheet | seat material S and the inversion ring 53 can be made substantially constant, the roll of moderate strength can shape the wet towel M by adding or subtracting the strength which winds up the sheet | seat material S. FIG.

In addition, since the conventional roll is roll-molded while conveying the sheet | seat material S to the conveyance direction downstream side in the wet towel manufacturing apparatus, the error in the molding was easy to arise due to the conveyance. In contrast, the roll of the present embodiment can be wound in a roll shape while supporting the sheet member S to the lower surface side of the inclined member 52b as described above in the wet towel manufacturing apparatus 1, thus suppressing the molding error accompanying the conveyance. The roll can form the wet towel M with stable precision.

Here, whether or not the forming of the wet towel M has been completed is determined whether the processing of S11 is started, that is, the rotation of the conveyance belt 51 and the inversion ring 53 is started, and roll forming of the sheet material S is started. Then, execution is performed by checking whether a predetermined time (hereinafter referred to as "molding time T _n ") has elapsed. In addition, when the starting belt 51 and the inversion ring 53 are not started at the same time, the measurement of the molding time T _n is based on the starting time of any one of the conveying belt 51 and the inversion ring 53. This can be measured.

Here, the molding time T _n is calculated according to the length of the sheet material S set by the user. That is, the value of the molding time T _n is proportional to the length L of the sheet material S set by the length setting dial 80, and the molding time is as long as the length of the sheet material S is long (short). The value of (T _n ) becomes large (small), and the time to roll forming becomes long (short).

Therefore, when the elapse of the molding time T _n in the process of S16 is confirmed, the roll molding of the sheet material S is completed and the roll means that the molding of the wet towel M is completed (S16: Yes). . Therefore, in this case (S16: Yes), by stopping the inversion motor 86a and stopping the rotation of the inversion ring 53 (S17), the roll discharges the wet towel M from the forming means 50.

That is, when roll forming is complete | finished between the inversion ring 53 and the opposing surface of the conveyance belt 51, the inversion ring by the process of S17, continuing rotation of the conveyance belt 51, and maintaining the moving speed. Only rotation of 53 is stopped and the moving speed is set to "0". Thereby, the sheet | seat material S by which roll forming was completed, ie, a roll, can discharge the wet towel M to the conveyance direction downstream side (left side of FIG. 3) of the conveyance belt 51. FIG.

Therefore, it is not necessary to convey (discharge) the sheet member S at the relative speed difference between the opposing surfaces while roll-forming the sheet member S as in the conventional towel manufacturing apparatus, and at the moving speed of the conveying belt 51 Since the sheet material S can be discharged, the discharge speed of the sheet material S can be increased by that much.

In addition, since the rolled-up wet towel manufacturing apparatus 1 of this embodiment is comprised with the two motors which are the conveying motor 85a which drives the conveyance belt 51, and the inverting motor 86a which drives the inversion ring 53, By stopping the rotation of the inversion motor 86a, only the rotation of the inversion ring 53 can be stopped while the rotation of the conveyance belt 53 is continued. Thus, as in the case where only one motor is configured to drive both the belts of the conveyance belt 51 and the inversion ring 53, to stop only the rotation of the inversion ring 53, that is, the rotational force transmission from the motor is reversed. Since the structure of the shaping means 50 can be simplified because there is no need to separately install a complicated mechanism such as releasing gears to stop only on the 53 side, the manufacturing cost of the shaping means 50 can be reduced. have.

In addition, the rolled paper towel M formed from the forming means 50 is conveyed to the downstream side by the conveyance belt 51 as described above, and is discharged to the mounting surface 5a of the support plate 5. In this case, since the vertical band 59 hangs in the downstream of the conveyance belt 51 (refer FIG. 3), it can suppress that the roll towel rolls on the conveyance belt 51 and the roll collapses.

After the roll is discharged from the wet towel M to the supporting plate 5 (S17), the driving of the conveying motor 85a is stopped and the rotation of the conveying belt 51 is terminated (S18). As a result, a series of processes for forming the roll towel M are completed. Therefore, the process shifts to S2 and waits while executing each process S3 until the next operation button 4a is pressed (S2: Yes). .

The driving of the transfer motor 85a is stopped when the predetermined time has elapsed after the driving of the inverting motor 86a is stopped in the process of S17. In this embodiment, the predetermined time is set to about 1 second. In the case where a plurality of scrolls continuously manufacture the towel M, the counter may be set in the RAM 73 to update the number value, and may be configured to repeat the processes from S4 to S18 by the counter value. .

Next, a method of replacing the towel roll R of the wet towel manufacturing apparatus 1 will be described. When replacing the towel roll R, first, the top cover 3 is opened to the upper side (upper side in FIG. 3), and the towel roll R supported by the roll supporting means 10, that is, the roll rotation guide Ra ) Is removed from the inside of the main body 2 to the outside. Next, a new towel roll R is introduced into the main body 2 to support the towel roll R, that is, the roll rotation guide Ra, by the roll supporting means 10, that is, the support groove 12.

Next, with reference to FIGS. 11 and 12, a description will be given of an aspect in which the scroll is manufactured by the wet towel manufacturing apparatus 1 and is aligned with the wet towel M being discharged to the support plate 5.

11 is a partially enlarged cross-sectional view of the rolled towel manufacturing apparatus 1, showing a state in which the support plate combined lid 5 is opened. 12 is a plan view of the support plate combined lid 5 seen from the arrow VII direction of FIG. In addition, in FIG. 11, for the convenience of description, the code | symbol of the rolled-up towel M was made into "M1-M4" in the manufacturing order. In addition, in FIG. 12, illustration of the towels M2-M4, the vertical band 59, etc. is abbreviate | omitted.

First, the first roll first manufactured in the forming means 50 is wiped by the conveyance belt 51 and discharged onto the mounting surface 5a as described above. In this case, since the regulating plate 5a1 is placed on the mounting surface 5a, the handkerchief M1 has a movement in which the movement is regulated by the regulating plate 5a1, and is substantially perpendicular to the discharge direction as shown in Fig. 12 (Fig. 12). In the vertical direction).

As a result, since the first scroll can suppress the wet towel M1 from slanting on the mounting surface 5a, each of the second and subsequent scrolls efficiently places the towels M2 to M4 on the mounting surface 5a of the limited area. More witable numbers can be made, and each of these scrolls can arrange the towels M1 to M4 on the 5a to provide a user with a good look.

Next, the second roll manufactured by the shaping | molding means 50, the wet towel M2 is conveyed by the conveyance belt 51 similarly to the above, and discharged on the mounting surface 5a. In this case, since the first roll has a wet towel M1 already placed on the mounting surface 5a, the scroll has a wet wipe M2 in the direction in which the scroll is regulated by the wet towel M1 and is substantially orthogonal to the discharge direction (up and down direction in FIG. 12). Aligned (see FIG. 11).

Next, the third rolled towel M3 manufactured by the forming means 50 is conveyed by the conveyance belt 51 as described above, and the upper end portions 5b1 and 5b2 formed on the rear end wall 5b of the support plate 5. ) Is discharged to the mounting surface 5a while inverted in contact with each other. As a result, the second hand towel M3, which has already been placed on the mounting surface 5a, may roll over the contact with the handkerchief M2, and thus may be over the tip side (left side of FIGS. 11 and 12) of the mounting surface 5a. To reach.

In addition, since the front end side of the mounting surface 5a is inclined downward toward the rear end wall 5b side as shown in FIG. 11, the handkerchief M3 descends to the rear end wall 5b side, and the movement is regulated by the control board 5a1. As a result, the third scroll can be aligned in the direction (up and down direction in Fig. 12) also roughly orthogonal to the ejection direction M3 (see Fig. 11).

Next, the fourth roll wet towel M4 manufactured by the forming means 50 is conveyed by the conveyance belt 51 as described above, and the upper end portions 5b1 and 5b2 formed on the rear end wall 5b of the support plate 5. ) Is discharged to the mounting surface 5a while inverted in contact with each other. As a result, if the scroll towel M4 is already placed on the mounting surface 5a, the second scroll can jump over the towel M2 and the third scroll M3. Thus, the fourth scroll is also aligned in the direction (up and down direction in Fig. 12) which is substantially orthogonal to the discharge direction on the tip side of the mounting surface 5a (see Fig. 11).

Therefore, when the roll towel is discharged toward the support lid 5, the roll may be turned over while the roll towel is in contact with the upper end portions 5b1 and 5b2 of the rear end wall 5b. It is possible to leap (M) farther in the discharge direction. As a result, in the case where the plurality of scrolls produce the towel (M), even if the scroll is already placed on the mounting surface (5a) of the support plate (5), even if the towel (M) is already placed, the plurality of scrolls The wet towel M can be scattered in the front-rear direction (left-right direction of FIG. 11) on the mounting surface 5a.

In addition, according to the roll towel manufacturing apparatus 1 of the present embodiment, since the support plate combined lid 5 can be separated from the main body 2, when a large amount of rolls are continuously produced in the towel M, By separating the support plate 5 and placing another container such as a tray on the front side of the main body 2, a large amount of rolls can be continuously produced in the main body 2 without clogging.

As described above, according to the wet towel manufacturing apparatus 1, the roll of the present embodiment is configured so that the thickness t and the length L of the sheet material S can be set, and the sheet material S is set according to the setting state. Since the amount of watering can be adjusted, the occurrence of excessive watering or lack of watering to the sheet material S can be suppressed. As a result, an appropriate moisture state can be suppressed regardless of the thickness t or length L of the sheet material S. Genie is a scroll that can produce a towel (M).

In addition, in the flowchart shown in FIG. 7, as a control means, each process of S5, S6, and S12-S15 is applicable, As a sprinkling time changing means, each process of S5, S12, and S14 is applicable, As a sprinkling flow rate changing means, S6 And each process of S13.

As mentioned above, although this invention was demonstrated based on the Example, this invention is not limited to the Example mentioned above, It can be easily estimated that various improvement changes are possible within the range which does not deviate from the meaning of this invention.

As described above, according to the rolled towel manufacturing apparatus according to the present invention, there is provided a designation means for designating information on sheet material, and adjusting means for adjusting the amount of watering by the watering means according to the information designated by the designation means. Therefore, by designating the information on the sheet material as the designation means, the amount of water to the sheet material can be adjusted by the adjusting means according to the information. As a result, a rolled towel made with appropriate moisture is produced in correspondence with the various sheet materials. You can do it.

In addition, according to the apparatus for manufacturing a rolled towel according to the present invention, when the thickness of the sheet material is specified by the thickness designating means, the amount of watering is adjusted by the adjusting means according to the thickness of the designated sheet material. There is an effect that can be suppressed, and as a result, a roll having an appropriate moisture state can be produced, regardless of the thickness of the sheet material.

In addition, according to the present invention, a roll towel manufacturing apparatus according to the present invention, when the length of the sheet material is specified by the length designating means, the amount of watering is adjusted by the adjusting means according to the length of the designated sheet material. There is an effect that can be suppressed, and as a result, a roll having an appropriate moisture state irrespective of the length of the sheet material can produce a wet towel.

And, since the adjusting means is provided with a sprinkling time changing means for changing the sprinkling time by the sprinkling means, for example, by changing the sprinkling time in accordance with the length of the sheet material to properly spray without excess or lack from the front end to the rear of the sheet material As a result, a scroll having an appropriate moisture state regardless of the length of the sheet member can produce a wet towel.

And, the adjusting means is provided with a sprinkling flow rate changing means for changing the sprinkling flow rate per unit time by the sprinkling means, for example, to change the sprinkling flow rate according to the thickness of the sheet material, or even if the thickness is the same By changing the watering flow rate, the sheet material can be sprayed properly without excessive or shortage, and as a result, a roll having an appropriate moisture state can be produced regardless of the thickness or length of the sheet material.

Therefore, when the sheet material is thick or long, the sprinkling flow rate is increased, while when the sheet material is thin or short, the sprinkling flow rate can be reduced so that the conveying speed of the sheet material can be increased without causing excessive sprinkling or lack of sprinkling. As a result, it is possible to achieve a reduction in the manufacturing time of the towel.

Further, according to the rolled-up wet towel manufacturing apparatus according to the present invention, the parameter table data relating the time parameter data or the flow rate parameter data and the thickness or the length of the sheet member is stored in the storage means, and the adjustment of the watering amount by the adjusting means. Since it is executed in accordance with each parameter data read by the reading means from the parameter table data, the user does not need to specify the watering time and the watering amount according to the thickness or length of the sheet material, but only specifies the thickness or length of the sheet material. In this way, the user's operation burden can be reduced by that much, and the speed of the watering quantity control can be reliably achieved.

Further, according to the present invention, a rolled towel is manufactured according to the present invention, wherein the sprinkling time of the sprinkling means in the case of sprinkling the sheet material after being cut into the sheet material by the forming means and cut by the cutting means. The post-cutting time parameter data is defined, and the parameter table data is stored in association with at least one of the thickness or the length of the sheet material. By sprinkling with sheet material for a specified sprinkling time, it is possible to suppress the occurrence of excessive sprinkling or lack of sprinkling, and as a result, a roll having an appropriate moisture state regardless of the thickness or length of the sheet material can be produced. For example, by changing the watering time according to the length of the sheet material, it is possible to suppress excessive watering in the thin or short sheet material, or lack of watering in the thick or long sheet material.

Further, according to the rolled towel manufacturing apparatus according to the present invention, the flow rate parameter data is a sheet member which is drawn out of the towel roll by the feeding means and introduced into the forming means, and the sheet member before being cut by the cutting means. In the case of sprinkling with water, the inlet flow rate parameter data defining the watering flow rate of the sprinkling means is provided, and the parameter table data includes the inlet flow rate parameter data with at least one of the thickness or length of the sheet material. It is associated and stored, so that by spraying the sheet material at the spraying flow rate defined by the flow rate parameter data at the time of drawing, for example, the tip of the sheet material to be introduced into the forming means in a suitable state, the water is excessively sprayed to the tip or It is possible to suppress the occurrence of molding failure in the molding means due to lack of watering. Will be.

Therefore, when the sheet material is thick or long, the sprinkling flow rate is increased, while when the sheet material is thin or short, the sprinkling flow rate can be reduced so that the conveying speed of the sheet material can be increased without causing excessive sprinkling or lack of sprinkling. As a result, it is possible to achieve a reduction in the manufacturing time of the towel.

In addition, according to the scroll wet towel manufacturing apparatus according to the present invention, the flow rate parameter data is a sheet material wound in a roll shape by the forming means, and in the case of spraying with the sheet material after being cut by the cutting means. Post-cutting flow rate parameter data defining the watering flow rate of the watering means, and in the parameter table data, the post-cutting flow rate parameter data is stored in association with at least one of the thickness or length of the sheet material, By cutting the sheet material with the watering flow rate defined by the flow parameter data after cutting, it is possible to suppress the occurrence of excessive watering or lack of watering, and as a result, a rolled towel having an appropriate moisture state regardless of the thickness or length of the sheeting material is produced. You can do it. For example, the watering flow rate is changed in accordance with the thickness and length of the sheet material, so that excessive watering in the thin or short sheet material or lack of watering in the thick or long sheet material can be suppressed.

Therefore, when the sheet material is thick or long, the sprinkling flow rate is increased, while when the sheet material is thin or short, the sprinkling flow rate can be reduced so that the conveying speed of the sheet material can be increased without causing excessive sprinkling or lack of sprinkling. As a result, it is possible to achieve a reduction in the manufacturing time of the towel.

In addition, the apparatus for manufacturing a rolled towel according to the present invention includes a watering flow rate setting means, and when the user sets the watering flow rate by the watering flow rate setting means, the watering flow rate is adjusted according to the setting value, so that the scrolling is damp The state can be set arbitrarily. In addition, since the sprinkling flow rate is adjusted between the predetermined minimum value data and the maximum value data, even if the sprinkling flow rate is inadvertently set by the sprinkling flow rate setting means, it is possible to prevent excessive sprinkling or lack of sprinkling and maintain an appropriate moisture state. Genie will be able to make a towel.

In addition, the sprinkling flow rate setting means outputs a resistance value depending on the stop position, and is composed of a rotary switch that is rotatable in a forward or reverse direction and is operable, so that the sprinkling flow rate setting means can be easily configured using a rotary switch. The user's operability can be improved.

In addition, according to the scroll wet towel manufacturing apparatus according to the present invention, the parameter table data defines the waiting time from the start of the withdrawal operation of the sheet material by the supply means to the start of the watering operation by the watering means. The initial waiting time parameter data is stored in association with at least one of the thickness or the length of the sheet material, and the watering by the watering means is executed after the elapse of the waiting time defined in the initial waiting time parameter data. For example, the tip portion of the sheet member introduced into the forming means can be sprayed at an appropriate timing according to its thickness or length, so that the occurrence of molding failure in the forming means due to excessive spraying or lack of spraying to the tip portion can be suppressed. do. In addition, since it is possible to suppress the sprinkling of useless water, moisture can be imparted to the sheet member efficiently with little water.

In addition, according to the scroll wet towel manufacturing apparatus according to the present invention, in the parameter table data, after the cutting operation is initiated by the cutting means and the waiting time after the cut is defined to start the watering operation by the watering means. The time parameter data is stored in association with at least one of the thickness or length of the sheet material, and the watering by the watering means is executed after the elapse of the waiting time defined in the waiting time parameter data after cutting, so that the thickness of the sheet material In addition, water can be sprayed at an appropriate timing corresponding to the length, and as a result, excessive water spraying or lack of watering of the sheet material can be suppressed, so that a roll having a proper moisture state can be produced, regardless of the thickness or length of the sheet material, and useless water spraying As moisture can be suppressed, moisture is added to the sheet material efficiently with little water. It is able to.

In addition, according to the scroll wet towel manufacturing apparatus according to the present invention, in the parameter table data, the preload driving force parameter data defining the preload driving force of the feeding means for a predetermined waiting time is associated with at least one of the thickness or the length of the sheet material. Since the conveying means is driven in accordance with the preload driving force defined in the preload driving force parameter data for a predetermined waiting time, the spraying means can immediately spray water from the spray nozzle when a predetermined waiting time elapses and the watering timing arrives. It works. In addition, since the preload driving force is related to the thickness and length of the sheet material, the response speed of watering can be changed according to the thickness and length of the sheet material. As a result, the excessive or sprinkling of the sheet material can be suppressed to reduce the thickness and length of the sheet material. Regardless of the appropriate moisture condition, scrolls can be produced.

Further, according to the rolled towel manufacturing apparatus according to the present invention, the water supply hose is turned so that its top portion passes through a position higher than the storage portion and the water spray nozzle, and the value of the preload driving force parameter data is transferred by the pressure feeding means. The preloading force is applied to the conveying means such that the water to be conveyed does not reach the top of the water hose. Therefore, even if the preload driving force is applied to the pressure feeding means for a predetermined waiting time to increase the response speed to the watering, the pumped water is not pumped over the top of the water supply hose, so that useless water can be sprayed from the water spray nozzle. By suppressing it, it becomes possible to give moisture to a sheet | seat material efficiently with little water.

In addition, according to the rolled towel manufacturing apparatus according to the present invention, the value of the initial waiting time parameter data is such that the waiting time when the length of the sheet material is at least shorter than the waiting time in other cases, The value of the variable data is such that the preload driving force when the length of the sheet material is at least shortest is larger than the preload driving force in other cases. That is, by delaying the timing of watering to the tip end portion of the sheet material introduced into the molding means, the tip end portion can be prevented from being excessively sprinkled, and the occurrence of molding failure in the molding means caused by the excessive sprinkling can be suppressed. In addition, when the spraying timing is delayed, the spraying timing may be delayed due to an error caused by various conditions, and the tip of the sheet material may become sprayed under the target value, so the preload driving force is increased to increase the response speed. It is possible to reliably suppress the shortage.

Further, according to the rolled-up wet towel manufacturing apparatus according to the present invention, at least the minimum value data of the flow rate parameter data at the time of introduction is defined as a value at which watering is not performed from the watering means, so that, for example, the lower limit value is set by the watering flow rate setting means. When set, i.e., when the roll having the smallest moisture condition is designated for the manufacture of the hand towel, the roll having the smaller moisture state can be reliably manufactured by not spraying the tip of the sheet material introduced into the molding means.
