Description

  The present invention relates to a hand towel manufacturing apparatus for manufacturing a hand towel by winding a sheet material such as a nonwoven fabric, paper or cloth.

  2. Description of the Related Art A hand towel containing an appropriate amount of moisture in a nonwoven fabric, paper, cloth or the like is widely used for wiping hands and the like in restaurants, homes and the like. In recent years, there has been developed a hand towel manufacturing apparatus for manufacturing hand towels by moistening moisture in a sheet material wound in a roll shape and cutting the sheet material into a predetermined length and then performing a winding process. This hand towel making apparatus is becoming popular because it can make hand towels on the spot and is hygienic.

  For example, in the hand towel manufacturing apparatus described in Patent Literatures 1 and 2, a sheet material wound in a roll shape is fed out, cut into a predetermined length, and water or hot water is injected to hydrate the feed belt and the outside. Between the belt and the belt or between the drum and the outer belt, and rolls to form a rod. FIG. 9 is a cross-sectional view of a hand towel 100 wound by these conventional hand towel apparatuses. As shown in FIG. 9, the hand towel 100 is wound outward with one end of one sheet material as the center.

Japanese Utility Model Publication No. 7-16691 Japanese Patent Laid-Open No. 10-192186

  As described above, the hand towel 100 wound by the conventional hand towel manufacturing apparatus is normally used after being unwound from the end and returned to a single sheet material. At this time, since one end portion of the sheet material is spirally wound, there is a problem that it takes time to unwind the sheet material. In addition, when the sheet material is too thin when it is unwound, there is a problem that it may be used after it is folded again in order to increase the thickness, and further time and effort is required. .

  Then, in this invention, it aims at providing the hand towel manufacturing apparatus which manufactures the hand towel which shortened the time until unwinding and using it.

  The hand towel manufacturing apparatus of the present invention is a hand towel manufacturing apparatus for manufacturing a hand towel by winding a sheet material, the transport belt operable in the hand towel discharging direction and the opposite direction thereof, and the sheet material on the transport belt. A conveying mechanism that feeds the sheet material, a winding unit that is disposed on the opposite side of the conveying belt and that rolls the sheet material that is conveyed on the conveying belt together with the conveying belt and rolls, and a sheet by the conveying mechanism When the material is fed out, the conveyance belt is operated in the direction opposite to the discharge direction in synchronization with the conveyance mechanism, and then the sheet material is drawn onto the conveyance belt in the direction opposite to the discharge direction, and then in synchronization with the conveyance mechanism. The sheet material that is continuously fed out by the conveying mechanism is folded on the sheet material on the conveying belt by moving the sheet It is obtained by a drive mechanism for causing the winding process by parts.

  According to the present invention, the sheet material fed out on the transport belt by the transport mechanism is once drawn in the direction opposite to the discharge direction by the transport belt that operates in synchronization with the transport mechanism, and is disposed on the transport belt. Thereafter, the sheet material arranged on the conveyor belt is sent out in the discharge direction by the conveyor belt. At this time, the sheet material fed out on the conveyance belt by the conveyance mechanism is folded on the sheet material arranged on the conveyance belt, and is wound by the winding unit in a folded state. The hand towel obtained in this way has half the length of the wound compared to the conventional hand towel that is not folded in half, so that the time and labor for unwinding can be halved. In addition, since it is folded in half when unwound, there is a sense of volume, and it is easy to use as a hand towel as it is.

  Here, it is desirable that the drive mechanism be folded from the center of the sheet material so that the outer surface becomes longer after winding. When the sheet material is wound by the winding unit in a folded state, the outer surface is shifted so as to be long, so the sheet material exposed to the outside of the hand towel after the winding process becomes one piece, A hand towel with beautifully arranged parts is obtained.

  The drive mechanism also includes a main gear that is rotated by a drive source, a first sub-gear and a second sub-gear that are driven by the main gear, and a forward / reverse motor that is driven by the first sub-gear to be rotated forward and backward. The main gear has a first arcuate gear formed in an arc shape in a part of the outer peripheral portion and an arcuate shape at a phase different from the phase of the first arcuate gear. The second arcuate gear is formed, the first auxiliary gear is disposed at a position where the first auxiliary gear is engaged with the first arcuate gear, and the second auxiliary gear is the first auxiliary gear. It is desirable that it is arranged at a position where it does not mesh with the arcuate gear and meshes with the second arcuate gear and the first auxiliary gear.

  Thus, when the main gear is rotated in one direction, the first arcuate gear formed in an arc shape on a part of the outer peripheral portion of the main gear and the first sub gear are engaged with each other. The sub-gear rotates in one direction, and the conveyance mechanism operates in one direction by the forward / reverse gear driven by the first sub-gear. At this time, since the second arcuate gear is arranged at a position different from the phase of the first arcuate gear, the second arcuate gear and the second subgear do not mesh with each other, and the first subgear does not mesh. Engage with gear and follow. Further, when the main gear further rotates in the same direction and the second arcuate gear and the second sub gear mesh with each other, the second sub gear is rotated in the direction of rotation of the first sub gear. Rotate in the same direction. At this time, since the first arcuate gear is arranged at a position different from the phase of the second arcuate gear, the first arcuate gear and the first subgear are not engaged with each other, and the first subgear is not engaged. The gear meshes with the second sub gear and rotates in the direction opposite to the rotation direction of the first sub gear. As a result, the transport mechanism operates in the direction opposite to the above-described direction by the forward / reverse rotation gear driven by the first sub gear. That is, the transport mechanism can be reciprocated in one direction and vice versa only by rotating the main gear in one direction.

(1) A conveying belt operable in the direction of discharging the hand towel and the opposite direction thereof, a conveying mechanism for feeding the sheet material onto the conveying belt, and a sheet material disposed on the opposite side of the conveying belt and conveyed on the conveying belt. A winding unit that winds and rolls a sheet material by nipping and rolling with the conveyance belt, and when the sheet material is fed out by the conveyance mechanism, the conveyance belt is operated in the direction opposite to the discharge direction in synchronization with the conveyance mechanism. After pulling the sheet material onto the conveying belt in the direction opposite to the discharging direction by the sheet material, the sheet material continuously fed out by the conveying mechanism is operated by operating the conveying belt in the discharging direction in synchronization with the conveying mechanism. And a drive mechanism for causing the winding processing section to perform winding processing. Bollywood is obtained. The resulting hand towel has half the length of the winding compared to a traditional hand towel that is not folded in half, so it only takes half the effort to unwind and shorten the time to unwind and use it. Can do. In addition, since the hand towel is folded in half in the unwound state, there is a sense of volume and it is easy to use as a hand towel in the state as it is.

(2) When the drive mechanism is folded and folded from the center of the sheet material so that the outer surface becomes longer after the winding process, Two end portions are not seen, and the sheet material exposed to the outside of the hand towel after the winding process becomes one sheet, so that a good-looking hand towel with the end portions neatly aligned can be obtained. Moreover, since the thickness of the edge part of the wound sheet material becomes thin, the hand towel which is hard to unwind naturally is obtained.

(3) The drive mechanism rotates the transport mechanism forward and backward by following the main gear that is rotated by the drive source, the first sub gear and the second sub gear that are driven by the main gear, and the first sub gear. The main gear has a first arcuate gear formed in an arc shape on a part of the outer peripheral portion, and an arcuate shape in a phase different from the phase of the first arcuate gear. The second sub-gear is formed at a position where the first sub-gear meshes with the first arc-shaped gear, and the second sub-gear is the first sub-gear. Is not meshed with the second arcuate gear, and is arranged at a position where it meshes with the second arcuate gear and the first sub-gear, so that the transport mechanism can be controlled only by rotating the main gear in one direction. Can be reciprocated in the direction and vice versa, and wound in a folded state. Was towel can be produced by the apparatus of simple structure. Further, since the structure is simple, there are few failures and the manufacturing cost can be reduced.

The temperature control device 12 is for keeping the water in the auxiliary tank 9 at a set temperature. The water in the auxiliary tank 9 is jetted from the jet nozzle 13 toward the sheet material P. A drain hose 90 is connected to the auxiliary tank 9, and a drain plug 91 is connected to the tip of the drain hose 90. By removing the drain plug 91, the water in the auxiliary tank 9 can be discharged.

  Next, the operation of the hand towel manufacturing apparatus having the above configuration will be described. FIG. 6 is a diagram showing a manufacturing process of a hand towel.

  When the motor 56 is driven clockwise in FIG. 2, the pulley 57 connected to the shaft of the motor 56 rotates clockwise, and the pulley 58 is rotated clockwise by the motor belt 59. As a result, the large-diameter gear 55 meshed with the pulley gear 58 a rotates counterclockwise, and the main gear 50 rotates clockwise via the drive gear 54. When the main gear 50 rotates, if the feed gear 50b of the main gear 50 and the feed gear 41 mesh with each other, the feed gear 41 rotates counterclockwise, and the sheet material P moves between the feed roller 40 and the feed guide 42. And is sent downward (see FIG. 6A).

  The fed sheet material P is irradiated with ultraviolet rays and sterilized by an ultraviolet irradiation device 7 provided in the middle of the conveyance belt 3, and then water is jetted from the jet nozzle 13. Thereby, moisture is contained in the sheet material P. When the sheet material P is fed to some extent, the reverse gear 50d of the main gear 50 and the reverse gear 52 are engaged with each other, and the reverse gear 52 rotates counterclockwise. This rotation is transmitted to the pulley 30 via the forward rotation gear 51, the counter gear 53, and the belt drive gear 32, and rotates the pulley 30 clockwise. At this time, the forward rotation gear 50c of the main gear 50 is not engaged with the forward rotation gear 51 because it is formed at a position different in phase from the reverse rotation gear 50d. Accordingly, the forward rotation gear 51 is free, and therefore follows the reverse rotation gear 52. As a result, the conveyor belt 3 rotates clockwise, and the sheet material P fed onto the conveyor belt 3 is drawn in the direction opposite to the hand towel discharge direction (the right direction in FIG. 2) (see FIG. 6B). . The pull-in length of the sheet material P is set by the arc length of the reverse rotation gear 50d.

  When the main gear 50 further rotates, the reverse gear 50d and the reverse gear 52 are disengaged, and the reverse gear 52 is not driven. Thereby, the conveyance belt 3 stops. At this time, the cam 43 of the main gear 50 pushes up the holding guide portion 42b, and the meshing of the feed gear 50b and the feed gear 41 of the main gear 50 is disengaged and the rotation of the feed roller 40 is stopped. P feed stops. At this time, the sheet material P is cut by the rotary cutter 44.

  When the main gear 50 continues to rotate, the forward rotation gear 50c of the main gear 50 and the forward rotation gear 51 mesh with each other, and the forward rotation gear 51 rotates counterclockwise. This rotation is transmitted to the pulley 30 via the counter gear 53 and the belt drive gear 32, and rotates the pulley 30 counterclockwise. Thereby, the conveyance belt 3 rotates counterclockwise (see FIG. 6C). At this time, since the forward rotation gear 50c and the reverse rotation gear 50d of the main gear 50 are formed at different phases, the reverse rotation gear 50d does not mesh with the reverse rotation gear 52. Accordingly, since the reverse gear 52 is free, it follows the forward gear 51, but the rotation of the reverse gear 52 does not affect other operations.

  Here, since the conveyance belt 3 is rotating counterclockwise, the sheet material P is almost folded in half from the center so as to overlap the sheet material P already on the conveyance belt 3, It is conveyed in the discharging direction (left direction in FIG. 2) (see FIG. 6C). When the transported sheet material P passes between the transport belt 3 and the guide plate 33, the leading end of the folded sheet material P is bent upward and is rotated clockwise. It is discharged onto the discharge tray 14 (see FIGS. 6D and 6E). Thereby, the hand towel T which has been wound in a folded state as shown in the sectional view of FIG. 7 is completed. At this time, the forward rotation gear 50c of the main gear 50 and the forward rotation gear 51 are disengaged, and the rotation of the conveyor belt 3 is stopped. At this time, since the projection 45 of the cam 43 is detected by the switch 6, the motor 56 is stopped.

  As described above, in the hand towel manufacturing apparatus according to the present embodiment, the transport belt 3 that can operate in the hand towel discharging direction and the opposite direction, the transport mechanism 4 that feeds the sheet material P onto the transport belt 3, and the transport belt 3. And a guide plate 33 that winds the sheet material P by nipping and rolling the sheet material P conveyed on the conveyor belt 3 together with the conveyor belt 3, and the sheet material P is conveyed by the conveyance mechanism 4. When the sheet is fed, the sheet material P is pulled onto the conveying belt 3 in the direction opposite to the discharging direction by operating the conveying belt 3 in the direction opposite to the discharging direction in synchronization with the conveying mechanism 4 and then synchronized with the conveying mechanism 4. Then, by operating the conveying belt 3 in the discharging direction, the sheet material P continuously fed out by the conveying mechanism 4 is folded on the sheet material P on the conveying belt 3, and the guide plate 33 By providing a drive mechanism 5 for causing the winding process due, towel T is obtained subjected to winding processing in folio state.

  The obtained hand towel T has half the length of the winding compared to the conventional hand towel 100 which is not folded in half, so that it takes half the time to unwind and shortens the time to unwind and use it. Is done. In addition, since the hand towel T is folded in half in the unwound state, it has a sense of volume and is easy to use as a hand towel in the state as it is.

  In the drive mechanism 5 in the present embodiment, the outer surface becomes longer after the winding process by adjusting the arc lengths of the feed gear 50b, the forward rotation gear 50c, and the reverse rotation gear 50d of the main gear 50. In this way, the sheet material P is folded and shifted from the center. As a result, when the sheet material P is wound by the guide plate 33 in a folded state, the outer surface is displaced so as to be long. The sheet material exposed to the outside becomes one sheet, and the end portion is neatly arranged and has a good appearance. Moreover, since the thickness of the end part of the wound sheet material P becomes thin, the hand towel T is not easily unwound.

  Further, in the drive mechanism 5 in the present embodiment, the transport mechanism 4 can be reciprocated in one direction and vice versa only by rotating the main gear 50 in one direction. It is simple, there are few failures, and the manufacturing cost can be reduced.

  In the hand towel manufacturing apparatus according to the present embodiment, after the sheet material P is cut, the feed gear 40 can be engaged with the feed gear 50b of the main gear 50 and the feed gear 41 to rotate the feed roller 40 slightly. Thereby, after the sheet | seat material P is cut | disconnected, it can be set as the state by which the sheet | seat material P was sent out a little, and manufacturing time can be shortened when manufacturing the towel T continuously. Further, in the present embodiment, the sheet material P is used that is wound in a roll shape, but it is also possible to use a sheet that has been cut into a predetermined length in advance.

  In the hand towel manufacturing apparatus according to the present embodiment, since the main gear 50 is configured to rotate in one direction, the motor 56 that is a drive source is configured to rotate only in one direction. When the sheet material P is jammed and biting occurs, it is difficult to remove the jammed sheet material P because the shaft of the main gear 50 having a large reduction ratio cannot be rotated in reverse. Therefore, in the hand towel manufacturing apparatus according to the present embodiment, the pulley 57 connected to the shaft of the motor 56 is provided with a groove 57a as a release mechanism for releasing the biting of the sheet material P. In addition, a hole (not shown) in which the groove 57a of the pulley 57 can be seen is provided in a part of the housing 1, and a minus driver is inserted into the groove 57a of the pulley 57 from this hole and rotated counterclockwise. This rotation is transmitted to the shaft of the main gear 50, and the main gear 50 rotates, whereby the rotary blade 44a rotates in the reverse direction. As a result, the gap between the rotary blade 44a and the swinging blade 44b is widened, so that the sheet material P is disengaged and the jammed sheet material P can be easily removed.

  Moreover, in the hand towel manufacturing apparatus according to the present embodiment, instead of the water tank 8, an external water tank 80 as shown in FIG. 8A, a commercially available PET bottle 81 as shown in FIG. Can be made wearable. At this time, the check valve 11 is attached to the lower part of the external water tank 80, the plastic bottle 81, and the like. Thereby, the capacity | capacitance of a water tank can be changed, without changing the magnitude | size of the hand towel manufacturing apparatus main body. Further, when the hand towel manufacturing apparatus is placed inside or outside the store, it is possible to attract more attention by attaching an advertisement or the like to the external water tank 80.

  Further, when a water tank made of a transparent material such as a plastic bottle 81 is used, when water enters the auxiliary tank 9 in the housing 1, bubbles are generated in the water tank, which can catch the eye. Furthermore, by attaching a light source 82 for illumination of a plurality of colors to the lower part of the water tank and lighting or flashing, the light of the light source 82 is reflected on the water in the water tank, and a more visual effect is obtained. Can be raised. In addition, an ultraviolet irradiation device may be provided below the water tank such as the external water tank 80 to sterilize the water.

  In addition, you may attach the ultraviolet irradiation device 7 in this embodiment anywhere in the sheet material accommodating part 2 or the passage route of the sheet material P. FIG. Further, the ultraviolet irradiation device 7 may use any of an ultraviolet lamp, an ultraviolet LED (light emitting diode) and the like. Further, in this embodiment, a pulley is used as a speed reducing means for driving the main gear 50. However, a gear is attached to the shaft of the motor 56 without using the pulley, and the main gear 50 is directly driven by this gear. It can also be set as the structure to do.

  The hand towel manufacturing apparatus of the present invention is useful as an apparatus for manufacturing hand towels by winding a sheet material on the spot in order to wipe hands and the like at restaurants and homes.
