The storage chamber 11 is a member for storing the towel roll R. As shown in FIG. 3, the storage chamber 11 is formed in a substantially U shape when viewed from the side, and is configured to open upward (upper side in FIG. 3). The towel roll R is stored in a storage space formed by the storage chamber 11, and is covered by an upper cover 3 that is covered from above the storage space.

  The storage chamber 11 is detachably attached to the main body 2. That is, the storage chamber 11 is configured as a substantially box-shaped body that is open at the top, and can be removed from the main body 2 by pulling out the box-shaped body upward (upward in FIG. 3). Such a box-like shape, with the back side of a guide groove 13 (described later) projecting on both side surfaces (the back side and the near side in FIG. 3) of the box-like body being fitted along the recesses recessed in the inner side surface of the main body 2. By pushing the body downward (downward in FIG. 3), the body is mounted in the main body 2 (see FIG. 1).

  The support groove 12 is a part for rotatably holding the towel roll R, and a pair of side wall portions of the storage chamber 11 facing each other outside both end surfaces of the towel roll R (the front side and the back side of the paper surface in FIG. 3). As shown in FIG. 3, it is recessed in a substantially arc shape in a side view. The towel roll R is rotatably held in the storage chamber 11 by loosely fitting a pair of roll rotation guides Ra inserted into the core of the towel roll R into the support groove 12.

  As shown in FIG. 3, a guide groove 13 extends linearly upward from the support groove 12. The guide groove 13 guides the roll rotation guide Ra inserted into the core of the towel roll R from the opening of the main body 2 to the support groove 12, and the roll rotation guide Ra is pulled out of the sheet material S (FIG. 3). The first and second side wall members 13a and 13b are provided so as to be opposed to each other with a predetermined interval therebetween.

  Therefore, when the towel roll R is exchanged, the roll rotation guide Ra can be guided by the guide path formed between the first and second side wall members 13a and 13b of the guide groove 13, so that the support groove 12 is moved to. The attachment / detachment work of the towel roll R can be facilitated, and the attachment work and the removal work of the towel roll R can be facilitated.

  Further, the upper end of the guide groove 13 (first and second side wall members 13a, 13b) is formed at substantially the same height as the upper end edge of the storage chamber 11, that is, the opening of the main body 2 (FIG. 1). As shown in FIG. 3, the width of the guide path at the upper end is widened in a tapered shape. Therefore, for example, even when the upper cover 3 cannot be fully opened and the guide groove 13 cannot be visually recognized, the roll rotation guide Ra can be easily inserted into the guide groove 13. As a result, the towel roll R can be easily attached.

  Further, as shown in FIG. 3, the upright direction of the second side wall member 13b is substantially vertical from the support groove 12 upward (upward in FIG. 3), so that the sheet material S reaches the end. A predetermined crossing angle can be formed between the sheet material S and the direction in which the roll rotation guide Ra is attracted (in the upper right direction from the support groove 12 toward the drive roller 23 in FIG. 3). As a result, the movement of the roll rotation guide Ra can be reliably restricted by the amount of the crossing angle. Therefore, when the sheet material S of the towel roll R reaches the end, the restriction by the second side wall member 13b. By the action, the rotational resistance of the drive roller 23 can be increased, and a current (overcurrent) of a predetermined value or more can be surely passed through the feed motor 81a (see FIG. 2).

  As shown in FIG. 3, the second side wall member 13 b does not necessarily have to extend substantially vertically upward. For example, the second side wall member 13 b has a substantially “<” shape in a side view (or an inverted “<” shape). ) May be bent. Thereby, the movement of the roll rotation guide Ra can be more reliably regulated by the inclined portion or the bent portion of the second side wall member 13b. Alternatively, a locking projection may be provided on the surface of the second side wall member 13b so as to project toward the first side wall member 13a. In this case as well, the roll rotation guide Ra can be locked and its movement can be reliably regulated.

  The feeding means 20 pulls out the sheet material S from the towel roll R rotatably held by the roll holding means 10 described above, and feeds the drawn sheet material S to the cutting means 30 and the water sprinkling section 42 described later. As shown in FIG. 3, the apparatus mainly includes a cover member 22, a drive roller 23, an auxiliary roller 24, and the like.

  The cover member 22 is a member for guiding the sheet material S pulled out from the towel roll R by a driving roller 23 and the like, which will be described later, in a predetermined direction, and as shown in FIG. 3, the upstream side (left side in FIG. 3). Is formed substantially horizontally, while the downstream side (the right side in FIG. 3) is formed in an arc shape along the outer periphery of the drive roller 23. A gap between the cover member 22 and the driving roller 23 is a conveyance path for the sheet material S. The sheet material S is guided downward by passing through this conveyance path, and is fed to the cutting means 30 and the water sprinkling unit 42 described later.

  A plurality of ribs extending in the feeding direction protrude from the curved surface of the cover member 22 that forms the conveyance path. Since the friction resistance with the sheet material S can be reduced by the rib, the sheet material S can be stably fed.

  The driving roller 23 and the auxiliary roller 24 are members for pulling out the sheet material S from the towel roll R and feeding the pulled sheet material S to the cutting means 30 and the water sprinkling unit 42 which will be described later through the above-described conveyance path. These are arranged so as to be able to sandwich the sheet material S as shown in FIG.

  The driving roller 23 is a rotating member that is driven by the above-described feeding motor 81a (see FIG. 2), and is configured such that a rubber ring-shaped body is provided around the outer peripheral surface thereof. Note that a plurality of the link-like bodies (four in this embodiment) are arranged with a predetermined interval in the width direction of the sheet material S (the direction perpendicular to the paper surface in FIG. 3). On the other hand, the auxiliary roller 24 is configured as one substantially rod-shaped body made of a metal material such as stainless steel, and both end sides thereof are rotatably supported by the cover member 22.

  Here, the cover member 22 is rotatably supported by the main body 2 via a shaft 22a and is urged in the direction of the drive roller 23 (counterclockwise in FIG. 3) by a torsion spring (not shown). . Therefore, the auxiliary roller 24 can be urged toward the driving roller 23 by the urging force of the torsion spring, and the sheet material S can be pressed against the driving roller 23. Therefore, the sheet material S can be reliably moved without sliding. Can be transported.

  Further, even when the sheet material S of the towel roll R reaches the end and the pull-out resistance of the sheet material S increases, the sliding of the driving roller 23 with respect to the sheet material S can be prevented. And an overcurrent can be reliably generated in the feed motor 81a (see FIG. 2). As a result, it is reliably detected that the sheet material S of the towel roll R has reached the end.

  Note that the urging force of the torsion spring that urges the cover member 22 toward the drive roller 23 is preferably about 50 g to about 250 g, and is set to about 150 g in this embodiment. This is because when the urging force is less than about 50 g, the sheet material S cannot be sufficiently pressed against the driving roller 23 and the driving roller 23 may slide with respect to the sheet material S. On the other hand, if it exceeds approximately 250 g, the rotational resistance of the drive roller 23 increases, and an excessive load acts on the feed motor 81a, so that an overcurrent may be erroneously detected.

  The cutting means 30 is an apparatus for cutting the sheet material S that hangs downward (downward in FIG. 3) from the feeding means 20 described above to a predetermined length, and mainly includes a fixed blade 31 and a rotary blade 32. Yes. The fixed blade 31 extends in the width direction of the sheet material S (perpendicular to the paper surface in FIG. 3), and a rotary blade 32 is rotatable at a position facing the fixed blade 31 with the sheet material S interposed therebetween. It is supported. The rotary blade 32 is connected to a cutting motor 82a (see FIG. 2) via a connecting gear (not shown), and the rotary blade 32 is counteracted by rotating the cutting motor 82a at a predetermined timing. The sheet material S rotated clockwise (leftward in FIG. 3) and sandwiched between the fixed blade 31 is cut at a position of a predetermined length from the tip.

  The water sprinkling means 40 is for applying moisture to the sheet material S, and mainly includes a tank storage chamber 41, an injection pump 83a, a heater 84a, a water sprinkling part 42, and the like. The tank storage chamber 41 is a member for detachably storing the water tank T, and is disposed on the back side (the right side in FIG. 3) of the main body 2 with respect to the feeding means 20. The water tank T is stored in the tank storage chamber 41 in an inverted state, and the water supply port Tm thereof is communicated with the injection pump 83a through the pump suction pipe.

  Thus, since the water tank T is arrange | positioned rather than the feed means 20 and the watering part 42 mentioned later on the back side (FIG. 3 right side) of the main body 2, as shown in FIG. Even when the sheet material S is pulled out by the feeding means 20, the water tank T can be exchanged in this state. Therefore, even when only the water tank T is exchanged when the replacement timing of the water tank T and the towel roll R does not match, the sheet once pulled out by the feeding means 20 to take out the water tank T from the main body 2. A troublesome operation such as rewinding the material S can be eliminated.

  As shown in FIG. 3, the discharge port of the injection pump 83 a is connected to the heater 84 a and the water sprinkling unit 42 via a water supply hose 43. As described above, the heater 84a is configured to hold (store) a predetermined amount of water in the internal storage chamber. When the heater switch (not shown) is turned on, the heater 84a supplies water in the storage chamber. Heat control is performed to maintain a predetermined temperature. The warm water heated in the heater 84a is sprinkled from the sprinkling portion 42 to the sheet material S.

  As described above, the heater 84a can naturally be configured to be able to cool water using a Peltier element or the like. In the present embodiment, the injection pump 83a is disposed on the upstream side of the heater 84a, but it is naturally possible to dispose the injection pump 83a on the downstream side of the heater 84a. That is, the pumping force of the injection pump 83a is applied as a suction force to the heater 84a, and the water sucked up from the heater 84a is pumped to the water supply hose 43.

  The water sprinkling means 42 is disposed on the front end side (right side in FIG. 3) of a cover member 52 to be described later, and includes a water sprinkling roller 42a, a water sprinkling main body 42b, and a nozzle portion 42c. The watering roller 42a is a rotating body formed in a substantially rod-like body from a metal material such as stainless steel, and is rotatably supported on the bottom surface side (lower side in FIG. 3) of the watering main body 42b, and a conveyance belt 51 described later. It arrange | positions so that it may contact with the conveyance surface. Therefore, when the conveying belt 51 is driven and the sheet material S is conveyed on the conveying belt 51, the watering roller 42a is rotated along with the conveyance of the sheet material S. The longitudinal dimension of the watering roller 42a is substantially the same as the lateral width of the conveyor belt 51 (dimension in the vertical direction in FIG. 3).

  The watering main body 42b is a member for storing water for watering the sheet material S, and is integrally formed with a cover member 52 described later from a resin material. The watering main body 42b is formed in a substantially box-like body having an internal space, and water ejected from a nozzle portion 42c described later is stored in the internal space.

  The watering roller 42a described above is rotatably supported by an opening formed in the bottom surface of the watering main body 42b, and a slight gap is provided between the watering roller 42a and the opening on the bottom surface. ing. Therefore, when the water sprayed from the later-described spray nozzle 42c is stored in the inner space of the watering main body 42b and the watering roller 42a is rotated by the start of driving of the conveyor belt 51, the water stored in the inner space is stored. Flows out from the opening by the rotation of the watering roller 42a and is sprayed onto the sheet material S.

  The front end side of the nozzle part 42c is opened in the watering main body 42b, and the water sent from the injection pump 83a via the water supply hose 43 is ejected into the internal space of the watering main body 42b and stored. The tip end side 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 (front side and back side in FIG. 3) is opened. The water can be ejected in the entire longitudinal direction.

  One sheet material S, which has been wetted by the sprinkler 42 and cut by the cutting means 30 to a predetermined length, is conveyed on the conveying belt 51 of the forming means 50 toward the downstream side (left side in FIG. 3). The In addition, since the water sprinkled from the water sprinkling part 42 and not absorbed by the sheet material S is collected by the water tray 7 to be described later via the conveyor belt 51 or the bottom surface of the case 54 (see FIG. 4), winding hand towel manufacturing It is possible to prevent dirt in the apparatus 1 and failure of electrical components.

  The forming means 50 is an apparatus for winding the sheet material S into a cylindrical shape (roll shape) and forming it into a wound towel M, and mainly comprises a conveyor belt 51, a cover member 52, and a reverse ring 53. Has been.

  The winding hand towel manufacturing apparatus 1 of the present embodiment is configured to form the winding hand towel M only on one side surface (upper side in FIG. 3) of the conveyor belt 51. Therefore, as described above, even when the sheet material S is pulled out toward the back surface side of the main body 2 due to the towel roll R being disposed on the front surface side of the main body 2, the molding processing path of the sheet material S is used. The hand towel M can be discharged from the front side of the main body 2 on which the operation panel 4 is disposed, and as a result, the hand towel manufacturing apparatus 1 can be reduced in size while being user-friendly. A good hand towel manufacturing apparatus 1 can be provided.

  The conveyor belt 51 is a rubber flat belt having a plurality of protrusions (not shown) in the entire outer peripheral surface, and is laid between a pair of rotating rollers 51a rotatably supported by a case 54 (see FIG. 4). Has been. A cover member 52 is disposed to face the conveying surface on the upper side (upper side in FIG. 3) of the conveying belt 51.

  The cover member 52 is formed with a plurality of protrusions 52a projecting in the shape of a washing plate between the surfaces facing the conveyor belt 51, so that an appropriate frictional force is applied to the sheet material S conveyed by the conveyor belt 51. Thus, the core of entrainment can be surely caused at the tip of the sheet material S. As a result, the sheet material S can be reliably wound in a roll shape centering on such a core, and molding defects can be suppressed.

  On the downstream side (left side in FIG. 3) of the cover member 52, an inclined member 52b is extended and inclined in the conveying direction (left direction in FIG. 3) of the sheet material S. The inclined member 52b is a member for holding the sheet material S at the time of roll forming, and a plurality of (six in the present embodiment, six in the present embodiment) are spaced apart in the width direction (perpendicular to the paper surface of FIG. 3) of the conveyor belt 51. ) Are arranged in a substantially comb shape.

  In addition, on the lower surface side (lower side in FIG. 3) of each inclined member 52, similarly to the cover member 52, a laundry plate-like protrusion is provided so as to project. Further, a part (two in this embodiment) of the plurality of inclined members 52b extends to a position where the tip side (left side in FIG. 3) can contact a rotating roller 53a of the reversing ring 53 described later. Thus, when the rotating roller 53a is moved upward, the upward movement is suppressed.

  A plurality of (in this embodiment, five) reversing rings 53 are disposed between the adjacent ones of the conveyor belts 51. The reversing ring 53 is a rubber ring, and is installed between a pair of rotating rollers 53 a that are rotatably supported by a case 54 (see FIG. 4). In order to wind in a roll shape, as shown in FIG.

  Here, both ends of the rotation roller 53a positioned on the conveyance direction side (left side in FIG. 3) of the sheet material S of the pair of rotation rollers 53a are rotatable and conveyed in a vertical groove 54a formed vertically in the case 54. The belt 51 is inserted so as to be movable toward the belt 51 (the lower side in FIG. 3) or the opposite side of the conveying belt 51 (the upper side in FIG. 3). Therefore, when the sheet material S is wound in a roll shape, the reversing ring 53 can be moved upward as the roll diameter increases, so that the hand towel M is formed regardless of the thickness of the sheet material S and the sheet length. Can be performed smoothly.

  A transport motor 85a (see FIG. 2) is connected to one of the rotation rollers 51a on which the transport belt 51 is installed via a plurality of gears. When the transport motor 85a is driven to rotate, the transport belt 51 is It is rotated counterclockwise (counterclockwise in FIG. 3). On the other hand, a reversing motor 86a (see FIG. 2) is connected to one of the rotating rollers 53a on which the reversing ring 53 is installed via a plurality of gears. When the reversing motor 86a is driven to rotate, the reversing ring 86a is rotated. 53 is rotated clockwise (clockwise in FIG. 3), that is, in the opposite direction to the conveyor belt 51. Note that the reduction ratio of each connecting gear and the output characteristics of the motors 85a and 86a are set so that the absolute speed conveyance of both opposing surfaces of the conveyance belt 51 and the reverse ring 53 is substantially equal.

  The sheet material S that has passed through the watering section 42 and is hung on the upstream side in the conveyance direction of the conveyance belt 51 (right side in FIG. 3) is conveyed toward the downstream direction (left direction in FIG. 3) by the rotation of the conveyance belt 51. The As a result, the core of the sheet material S is raised between the opposing surfaces of the cover member 52 and is held on the lower surface side of the inclined member 52b between the opposing surfaces of the reversing ring 53. Then, it is formed into a cylindrical wound hand towel M by being wound in a roll shape around the induced nucleus.

  Note that the opposing surfaces of the reversing ring 53 and the conveyor belt 51 are moved at substantially equal speeds in opposite directions as described above. Therefore, since the relative speed difference between the opposing surfaces can be increased, the winding speed of the sheet material S can be increased, and the time required for forming the hand towel M can be shortened accordingly.

  When the forming of the winding hand towel M is completed, the rotation of the reversing ring 53 is stopped, so that the winding hand towel M is transported toward the downstream side (left side in FIG. 3) by the rotation of the transport belt 51, and a tray serving lid 5 described later. Released on top.

  As shown in FIG. 3, a hanging band 59 is suspended from the case 54 (see FIG. 4) on the downstream side of the conveyor belt 51. The hanging band 59 is a member for preventing the winding of the hand towel M from being collapsed during conveyance, and is configured from a flexible rubber material into a sheet shape having a lateral width substantially equal to that of the conveyance belt 51. . Therefore, the wound hand towel M transported on the transport belt 51 is transported to the downstream side while the outer peripheral surface is rubbed against the hanging belt 59, so that the wound hand towel M is transported without rolling, and the wound hand towel It can suppress that winding of M collapses.

  Since the winding hand towel M is wound clockwise (FIG. 3 clockwise) around the core of the winding, it is rubbed in the winding direction by the drooping belt 59, and the end of the winding is not unraveled. Further, the base (upper side in FIG. 3) of the hanging band 59 is rotatably supported by the case 54 (see FIG. 4), and is configured to be movable up and down as the wound hand towel M is conveyed. Further, the drooping belt 59 is provided with a plurality of protrusions on the surface facing the conveying belt 51 (right side in FIG. 3) so as to increase the contact resistance to the winding towel M. .

  As shown in FIG. 3, a tray serving lid 5 is disposed at the downstream end (left side in FIG. 3) of the forming means 50 (conveying belt 51) on the front side (left side in FIG. 3) of the main body 2. A water pan 7 is disposed below the pan / cap 5.

  As described above, the lid 5 serving as a tray is used as a tray for placing a plurality of wound towels M when opened, and when closed, the front side of the main body 2 is closed on the back side. Used as a lid (see FIG. 1). Moreover, the water tray 7 is a container for collecting the water sprayed from the nozzle part 42c of the water sprinkling part 42, and is configured to be detachable from the opening 2b that opens on the front side of the main body 2 (left side in FIG. 3). ing. Here, with reference to FIG.4 and FIG.5, the detailed structure of the saucer combined lid 5 and the water saucer 7 is demonstrated.

  4 and 5 are partially enlarged cross-sectional views of the wound-wet hand towel manufacturing apparatus 1, and show a state where the tray-and-use lid 5 is closed and a state where it is opened, respectively.

  The tray-use lid 5 includes a placement surface 5a on which the hand towel M is placed, a rear end wall 5b erected from the rear end side (lower side in FIG. 4, left side in FIG. 5) of the placement surface 5a, The mounting surface 5a and the rear end wall 5b are mainly provided with a pair of side wall portions 5c provided opposite to each other (FIG. 4 and FIG. 5 on the rear side and the front side). The upper part (left side of FIG. 4, upper side of FIG. 5) is opened from the member, and is configured in a container shape that can hold a plurality of wound towels M (see FIG. 6).

  As shown in FIGS. 4 and 5, the mounting surface 5 a is inclined upward and downward on both sides in the front-rear direction (the left-right direction in FIG. 5), and has a substantially concave shape in a side sectional view shown in FIG. 5. A restricting plate 5a1 is provided upright at a substantially central portion in the front-rear direction of the placement surface 5a. The restricting plate 5a1 is a member for restricting and aligning the movement of the winding hand towel M released from the conveying belt 51 onto the placement surface 5a. It is formed so as to extend in a direction (perpendicular to the paper surface of FIGS. 4 and 5) that is substantially perpendicular to the discharge direction of the hand towel M (see FIG. 7), with an interval greater than the diameter (see FIG. 6).

  The upper end of the rear end wall 5b (the left side in FIG. 4 and the upper side in FIG. 5) is a part for jumping the hand towel M that has been transported by the transport belt 51 toward the transport surface, as shown in FIG. When the tray / lid 5 is opened, it is configured to be adjacent to the downstream end (right side of FIGS. 4 and 5) of the conveyor belt 51. Therefore, when the hand towel M is transported from the transport belt 51, the hand towel M can be brought into contact with the upper end portion of the rear end wall 5b and bounced back, so that the hand towel M is moved further away from the mounting surface 5a. You can jump towards.

  Further, the upper end portion of the rear end wall 5b is formed in a one-step substantially staircase shape that descends toward the placement surface 5a. That is, since the upper step portion 5b1 disposed on the conveying belt 51 side and the lower step portion 5b2 disposed on the placement surface 5a side are formed on the stepped portion, the hand towel M is placed on the upper step portion. 5b1 and the lower step part 5b2 can be brought into contact with each other and bounced back in sequence, so that it is possible to jump toward the placement surface 5a without impeding the momentum of the wound hand towel M.

  As described above, according to the hand 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 conveyor belt 51 in a state in which the tray / lid 5 is opened. Since it is comprised in this way, the winding hand towel M can be directly discharge | released from the conveyance belt 51 to the mounting surface 5a of the saucer combined lid 5. Therefore, like a conventional wound towel manufacturing apparatus, a guide plate is installed between the conveyor belt 51 and the tray-use lid 5 and is rolled on the guide plate, so that the wound towel is received up to the tray-use lid 5. There is no need to transport.

  Therefore, not only can the guide plate be eliminated, but the number of parts can be reduced to reduce the product cost of the entire wound towel manufacturing apparatus 1 as well as the conventional wound towel manufacturing apparatus. Since the winding of the hand towel M can be prevented from collapsing when rolling, the hand towel M can be provided to the user in a good winding state.

  Projecting shafts 5c1 project from the outer surfaces of the side wall portions 5c (the back side and the near side in FIGS. 4 and 5), and the projecting shafts 5c1 are held in a support plate 8 that will be described later. The groove 9 is rotatably and detachably held. Accordingly, as shown in FIGS. 4 and 5, the tray-use lid 5 is configured to be openable and closable with the protruding shaft 5 c 1 as a fulcrum, and by removing the protruding shaft 5 c 1 from the holding groove 9, It is configured to be removable from.

  The support plate 8 is a pair of plate-like members disposed opposite to each other on the outer sides of the side wall portions 5 c, and holding grooves 8 are recessed in both opposing surfaces of the support plate 8. The holding groove 8 is a concave groove having a substantially U-shaped cross section for holding the above-described protruding shaft 5c1 in a rotatable and detachable manner, and as shown in FIGS. 4 and 5, the lower end side thereof (see FIGS. 4 and 5). 5), the projecting shaft 5c1 is rotatably held by a holding portion formed in an arc shape, and the projecting shaft 5c1 is removed from the opening formed on the upper end side (the upper side in FIGS. 4 and 5). Or it can be inserted.

  Further, as shown in FIGS. 4 and 5, the passage path of the holding groove 9 that connects the lower end side holding portion and the upper end side opening portion is formed to be bent in a substantially square shape when viewed from the front. Therefore, when the user opens / closes the pan / lid 5, even if the pan / cap 5 is inadvertently lifted upward, the protruding shaft 5 c 1 of the pan / cap 5 is removed from the opening of the holding groove 9. Since it can suppress that it removes, it can suppress that the saucer combined lid 5 remove | deviates from the main body 2 at the time of opening / closing operation. As a result, the operability of the opening / closing operation of the tray / lid 5 can be improved.

  Note that the passage of the holding groove 9 is directed toward the back side of the main body 2 (right side in FIGS. 4 and 5), that is, the holding portion on the lower end side is closer to the back side (back side) of the main body 2 than the opening on the upper end side. 5), the opened tray and lid 5 can be inserted into the main body 2 as shown in FIG. Therefore, since the amount of protrusion of the opened pan / lid 5 from the front side of the main body 2 (the left side in FIGS. 4 and 5) can be reduced, the pan / lid 5 becomes obstructive and the winding hand towel manufacturing apparatus 1 It can suppress that an installation place is restrict | limited or the beauty | look of the winding hand towel manufacturing apparatus 1 is impaired.

  Further, by configuring the holding groove 9 to bend in this way, when removing the pan / lid 5, the pan / cap 5 is moved toward the front side of the main body 2 (left side in FIGS. 4 and 5). Removal is possible by lifting upwards. That is, since it is not necessary to move the tray / lid 5 toward the back side (the right side in FIGS. 4 and 5) of the main body 2, the tray / lid 5 and each member in the main body 2 (for example, the transport belt 51). Therefore, it is not necessary to provide an empty space for avoiding the interference, and the size of the entire winding hand towel manufacturing apparatus 1 can be reduced accordingly.

  As shown in FIGS. 4 and 5, an optical sensor 120 is disposed on the side wall of the opening 2 b of the main body 2. This optical sensor 120 is a sensor for detecting the open / closed state of the pan / lid 5 based on a change in the amount of reflected light, and receives a light emitting element 120a as a light source for emitting infrared light and the reflected light. And a light receiving element 120b. As shown in FIGS. 4 and 5, the light emitting surface of the light emitting element 120 a and the light receiving surface of the light receiving element 120 b can be opposed to the side wall portion 5 c of the tray cover 5 as shown in FIG. It is arrange | positioned on the same surface of a side wall.

  In the optical sensor 120 of the present embodiment, the light emitting element 120a is composed of an infrared LED, and the light receiving element 120b is composed of a phototransistor. However, the irradiation light is not limited to infrared rays, and it is naturally possible to irradiate (receive) light of other wavelengths.

  When the infrared ray irradiated from the light emitting element 120a and reflected by the object (the side wall portion 5c of the pan / lid 5 or the opposite side wall) is received by the light receiving element 120b, the amount of received light is detected by the sensor control circuit 89 (see FIG. 2). ) Are converted into digital values by the CPU 71 (see FIG. 2). The CPU 71 determines the open / closed state of the tray cover 5 depending on whether or not the read value is equal to or greater than a predetermined threshold value.

  Specifically, when the pan / lid 5 is closed, as shown in FIG. 4, the side wall 5c of the pan / cap 5 is disposed immediately before the light-emitting device 120a. The infrared light thus reflected is directly reflected by the side wall 5c of the tray / lid 5, and the amount of light received by the light receiving element 120b is large (above a threshold value). On the other hand, when the pan / lid 5 is opened, as shown in FIG. 5, since there is no obstacle in front of the light emitting element 120a, the infrared light irradiated from the light emitting element 120a is The amount of light received by the light receiving element 120b reflected by the side wall on the opposite side of the opening 2b is small (below the threshold value). As a result, it is possible to detect the open / closed state of the tray cover 5 according to the amount of light received by the light receiving element 120b.

  In addition, as shown in FIG. 5, the rolling hand towel manufacturing apparatus 1 of the present embodiment is arranged close to the side wall portion 5c edge (upper edge in FIG. 5) of the tray-and-use lid 5 in which the optical sensor 120 is open. 4, even if the tray / lid 5 is not completely closed as shown in FIG. 4, i.e., when the tray / lid 5 is in a half-open state, the optical sensor 120 is activated when the tray / lid 5 is opened. There is no detection. That is, the rolling hand towel manufacturing apparatus 1 of the present embodiment causes the optical sensor 120 to detect that the tray / lid 5 is opened when the tray / lid 5 is completely opened as shown in FIG. be able to.

  When the optical sensor 120 detects that the saucer-combined lid 5 is closed, the CPU 71 (see FIG. 2) disables the pressing of the operation / stop button 4a and prohibits the manufacture of the hand towel M as described above. To do. Therefore, for example, even when the user presses the operation / stop button 4a with the tray serving lid 5 closed, and instructs the manufacture of the hand towel M, the start of the manufacture is avoided. Therefore, the wrapping towel M does not reach the tray / lid 5 and the wrapping towel M is clogged in the main body 2 (forming means 50). Further, the transport / reverse motor 85a is caused by the clogging. , 86a can be avoided in advance due to an excessive load.

  Further, as described above, the rolling towel manufacturing apparatus 1 of the present embodiment is configured such that when the tray-combined lid 5 is closed, the tray-combined lid 5 blocks the front of the optical sensor 120 (see FIG. 4 and FIG. 5), when the pan / lid 5 is removed from the main body 2, the optical sensor 120 may generate the same detection result as when the pan / cap 5 shown in FIG. 5 is opened. it can.

  Therefore, even if the pan / lid 5 is removed from the main body 2, the manufacture of the winding towel M is not prohibited, so whether or not the pan / cap 5 is removed so that the prohibition operation does not operate. Since it is not necessary to separately provide a detecting means for detecting or a releasing means for canceling the prohibition operation and the configuration can be simplified, the number of parts and the design cost can be reduced, and accordingly, the entire hand towel manufacturing apparatus 1 As a result, the product cost can be reduced.

  In addition, when the side wall part 5c of the saucer combined lid | cover 5 is comprised with light color (for example, white etc.), the side wall of the opening part 2b on the opposite side to the arrangement | positioning surface of the optical sensor 120 is dark color (for example, black etc.). ), And when the side wall 5cS is formed in a dark color, it is preferable that the side wall of the opening 2b be formed in a light color. Thereby, the light quantity difference of the reflected light which changes according to the opening-and-closing state of the saucer combined lid 5 can be enlarged, and the detection accuracy of the optical sensor 120 can be improved.

  As shown in FIGS. 4 and 5, a water tray 7 is detachably disposed below the tray serving lid 5. The water tray 7 is a container for collecting water sprinkled from the water sprinkling part 42 described above and not absorbed by the sheet material S, and is a substantially box-shaped body whose upper surface side (upper side in FIGS. 4 and 5) is opened. It is configured.

  As described above, the opening 2b is formed on the front side (the left side of FIGS. 4 and 5) of the main body 2, and the water tray 7 has the opening 2b regardless of the open / closed state of the tray serving lid 5. It is comprised so that attachment or detachment is possible. Therefore, it is not necessary to remove the front panel of the apparatus main body as in the conventional hand towel manufacturing apparatus, and the operation for attaching and detaching the water tray 7 is simplified, so that the water stored in the water tray 7 is easily discarded. be able to. In addition, guide members (not shown) are disposed on both sides of the horizontal direction of the water tray 7 (the vertical direction in FIG. 4 and FIG. 5). And the horizontal direction in FIG. 5), the movement is guided.

  As shown in FIGS. 4 and 5, the collecting member 6 is disposed between the water tray 7 and the conveyor belt 51. The collecting member 6 is a member for collecting water that has flowed down along the conveyor belt 51 or the bottom surface 54a of the case 54 and sending it to the water receiving tray 7. The upper end (see FIG. 4 and the upper side of FIG. 5 is formed so as to have a slightly larger width than the width of the bottom surface 54a (the vertical dimension in FIG. 4 and FIG. 5). The water collected by the collecting member 6 is sent into the water receiving tray 7 from a delivery port 6a formed with a reduced diameter at the lower end of the collecting member 6.

  In this way, the water flowing down from the conveyor belt 51 etc. is collected by the collecting member 6, so that the lateral width of the water receiving tray 7 (dimension in the vertical direction in FIG. 4 and FIG. 5) is made narrower than the lateral width of the conveyor belt 51 etc. can do. Therefore, unlike the conventional hand towel manufacturing apparatus, it is not necessary to configure the lateral width of the water tray wider than the lateral width of the conveyor belt in order to directly collect the water flowing down from the conveyor belt. Therefore, since the width of the water tray 7 can be reduced accordingly, the space for providing the above-described guide member can be secured on both sides of the water tray 7 in the width direction. The width of 1 can be made compact.

  Here, on the upper surface side (the upper side of FIGS. 4 and 5) of the water receiving tray 7, a lid member 7 a that covers the upper surface opening portion is detachably mounted, and the lid member 7 a has the collecting member 6. An opening 7a1 is formed at a position corresponding to the delivery port 6a. Therefore, at the time of taking out the water tray 7, even if the water tray 7 is shaken or tilted, the lid member 7a prevents the water stored inside from flowing out. Therefore, such a removal operation can be performed safely and quickly.

  In addition, it is preferable to comprise at least one of the water receiving tray 7 or the cover member 7a from a transparent resin material. When the water tray 7 is made of a transparent resin material, the water tray 7 is not taken out from the main body 2, i.e., is left installed in the main body 2, and the water tray is opened from the opening 2 b of the main body 2. The amount of water in 7 can be visually confirmed. On the other hand, when the lid member 7a is made of a transparent resin material, the amount of water in the water tray 7 can be visually recognized without removing the lid member 7a.

As a result, the third wound towel M3 can also be aligned in a direction (vertical direction in FIG. 7) substantially orthogonal to the discharge direction (see FIG. 6).

  Next, the fourth hand towel M4 manufactured by the forming means 50 is transported by the transport belt 51 in the same manner as described above, and is applied to the upper step portion 5b1 and the upper step portion 5b2 formed on the rear end wall 5b of the tray-use lid 5. It is released toward the mounting surface 5a while being bounced back in contact with the order. As a result, the wound towel M4 can jump over the second wound towel M2 and the three-roll wound towel M3 already placed on the placement surface 5a. As a result, the fourth hand towel M3 is also aligned in the direction (vertical direction in FIG. 7) substantially perpendicular to the discharge direction on the tip side of the placement surface 5a (see FIG. 6).

  Thus, according to the rolled hand towel manufacturing apparatus 1 of the present embodiment, when the wound hand towel M is released toward the tray-and-use lid 5, the wound hand towel M is moved to the upper end portion (upper end portion 5b1) of the rear end wall 5b. And the lower step 5b2) can be brought into contact with and bounced back, so that the hand towel M can be jumped further in the discharge direction. As a result, when a plurality of wound towels M are manufactured, even if the wound towel M is already placed on the placement surface 5a of the tray-and-use lid 5, it is possible to exceed this. The hand towel M can be scattered in the front-rear direction (left-right direction in FIG. 6) on the placement surface 5a.

  In addition, according to the rolled hand towel manufacturing apparatus 1 of the present embodiment, the pan / cap 5 is configured to be detachable from the main body 2. By removing the lid 5 and separately installing another container such as a jar on the front side of the main body 2, it is possible to continuously manufacture a large amount of wound hand towels without clogging the main body 2.
