The present invention relates to a wet towel rolling device for producing a towel by rolling a sheet material such as cloth or paper into a rod shape.

Generally, wet wipes are made by infiltrating moisture into sheet materials such as cloth and paper, and rolling the wet sheet materials into rod shapes. There is a device for rolling a towel as a device for manufacturing a towel by rolling up a sheet material. 9 and 10 are cross-sectional schematic diagrams illustrating the operation of a conventional wet wipe device.

The conventional wet towel rolling device shown in Fig. 9 is a drum-type wet towel rolling device. A rotating belt 51 is wound around the outer circumference of the rotating drum 50 so that the rotating drum 50 and the rotating belt 51 rotate integrally. The fixing belt 52 is installed to cover about five-eighth from the top of the outer circumference of the rotating belt 51 downward, and the upper end of the fixing belt 52 is the fixing fitting 53, and the fixing belt 52 is fixed. The lower ends of the are fixed with fixing fittings 54, respectively. In the vicinity of the top of the rotary belt 51, there is almost no gap between the rotary belt 51 and the fixed belt 52, and the rotary belt 51 is arrange | positioned so that the clearance may gradually widen downward. When the sheet material T is inserted between the top of the rotating belt 51 and the fixing belt 52, the sheet material T is conveyed by the rotating belt 51 and is caused by friction between the fixing belt 52 and the fixing member. By being returned, it rolls up in the shape of a rod, moving downward along the fixing belt 52.

In addition, the conventional wipes drying apparatus shown in FIG. 10 is an endless belt type wipes drying apparatus. The endless belt 55 supported by the drive roller 59 and the driven roller 57 is fixed to the tensioning side (upper side in FIG. 10) generated by the rotation of the drive roller 59 and the driven roller 57. One end of 61) is in contact. The fixed belt 61 is attached to the pressure plate 60 which is rotatable about the fixed shaft 63. Then, one end of the fixing belt 61 is pressed against the endless belt 55 by the elastic force of the spring 64 caught between the fixing fitting 62 and the pressure plate 60. In the advancing direction of the endless belt 55, the gap between the endless belt 55 and the fixed belt 61 gradually widens. When the sheet member T is mounted on the endless belt 55 on the driven roller 57 side, and the sheet member T is inserted between the fixing belt 61 and the endless belt 55, the sheet member T By returning by friction between the fixed belt 61 and being conveyed by the endless belt 55, the sheet member T is dried in a rod shape while moving along the endless belt 55.

However, the conventional wet wipes are all supported by a fixed fitting with a fixed fitting, and the distance between the fixed belt and the rotating belt or the endless belt cannot be adjusted every time the sheet material is wound. For this reason, the sheet | seat material of different thickness could not be rolled and manufactured with a wet towel, without re-adjusting a wet wipe apparatus.

The wet towel manufacturing apparatus 1 shown in FIG. 1 is an apparatus which impregnates the sheet | seat material T, such as cloth, paper, and a nonwoven fabric, and rolls it in rod shape, and manufactures a wet towel. The wet towel manufacturing apparatus 1 is installed in a restaurant or the like, and when a customer or an employee presses the switch 6, manufacturing of the wet towel is performed in the housing 5, and the finished wet towel is discharged from the outlet 7.

The tank 10, the drum 11 in which the sheet | seat material T is wound in roll shape, the roller 12 which conveys the sheet | seat material T, the motor 15, and the sheet | seat material are contained in the wet towel manufacturing apparatus 1 inside. Cutter 14 for cutting (T) to a predetermined size, nozzle 25 and tank 10 for spraying water onto sheet material T, heater 26 to warm the water, and sheet material T ), A towel-drying device for winding a towel 30 and the like are provided.

The wet towel rolling device 30 is built in the housing 5 of the wet towel manufacturing apparatus 1 as a device for winding the sheet material T into a rod shape. The wet towel rolling device 30 is mainly composed of an endless belt 45 including a contact member 35 and a retaining fitting 40. The contact member 35 is formed by bending a metal plate in a U shape to form rectangular bottom surfaces 35a and standing portions 35b and 35c. The contact members 35 are curved in a convex shape when viewed from the side in the center thereof, and are formed in the longitudinal direction. It has a cotton. The fixing belt 37 which is a sheet-shaped rubber material is attached to the upper surface of this surface, and the contact surface 37a is formed in the surface of the fixing belt 37. As shown in FIG. The contact surface 37a means the surface which contacts the belt surface 45a of the endless belt 45 mentioned later. One end (left side in FIG. 3) of the bottom surface 35a is provided with a guide 36 that extends upward. The curved shape of the guide 36 is a shape along the curved surface of the drive roller 42 described later.

The retaining fitting 40 bends a metal plate to form a rectangular base plate portion 40a and a side portion 40b. The shaft 41 is provided between the side surface parts 40b of both sides of one side edge part of the holding fitting 40 (left side in FIG. 3). Both ends of the shaft 41 are equipped with an E-ring 41a so as not to fall out of the side surface 40b. The drive roller 42 is fixed between the side parts 40b of the shaft 41, and is rotatably supported between the side parts 40b and the shaft 41 integrally. The pulley 46 is fixed to the outer side of the side part 40b of the shaft 41 of one side (rear of FIG. 3).

The shaft 43 is provided between the side parts 40b on both sides near the other end of the holding fitting 40 (the right side in FIG. 3). Both ends of the shaft 43 protrude from the side part 40b. The driven roller 44 is provided in the outer periphery of the shaft 43 between the side parts 40b, and is rotatable independently of the shaft 43. As shown in FIG. An endless belt 45 is wound around the drive roller 42 and the driven roller 44. The endless belt 45 is a rubber belt. The pulley 47 is fixed to the outer side of the side part 40b at one end (back of FIG. 3) of the shaft 43, and the belt 48 is wound between the pulley 46. As shown in FIG. One end of the shaft 43 is inserted into a hole formed in the standing portion 35c (back of FIG. 3) of the contact member 35, while the other end of the shaft 43 (front of FIG. 3) is a standing portion. One end of the holding fitting 40, that is, the endless belt 45, is axially supported by the contact member 35 via 35b (the front part of FIG. 3). As a result, the endless belt 45 is connected to the contact member 35 so as to be able to swing (in the direction of arrow a shown in FIG. 4). The belt surface 45a of the endless belt 45 is in contact with the contact surface 37a of the fixed belt 37 due to its own weight, such as the endless belt 45 and the retaining fitting 40.

The gear 33 is attached to the distal end portion of the shaft 43 protruding outward from the standing portion 35b of the contact member 35 so as not to fall off by the E-ring 33a. The gear 33 is meshed with a motor gear 32 rotatably provided by the motor 31. As the motor 31 rotates, the shaft 43 rotates via the motor gear 32 and the gear 33. When the shaft 43 rotates, the shaft 41 rotates via the pulley 47 and the belt 48, and the driving roller 42 rotates. As the drive roller 42 rotates, the endless belt 45 rotates. In addition, the direction of the rotational movement of the endless belt 45 is a direction shown by the arrow b of FIG. 5A. The shape of the belt surface 45a on the relaxed side of the endless belt 45 corresponds to the curved shape of the fixed belt 37.

In addition, as shown in FIG. 5A, the shaft 43 is provided such that a slight gap is formed between the contact surface 37a of the fixed belt 37 near the driven roller 44 and the belt surface 45a of the endless belt 45. The shaft is axially supported by the standing portions 35b and 35c of the contact member 35. This gap is sufficient to allow the sheet material T having a large diameter to be completely rolled up to be discharged without being blocked between the fixed belt 37 and the endless belt 45.

Next, the operation of the wet towel drying device 30 in the present embodiment will be described. First, a person who needs a wet towel presses the switch 6 of the wet towel manufacturing apparatus 1. Then, the motor 15 rotates, the roller 12 rotates via the gearwheel 13, and the sheet | seat material T wound around the drum 11 is pulled under the rear part of the housing 5. When the sheet material T passes downward through the cutter 14 about 200 mm, the cutter 14 touches the sheet material T and the sheet material T is cut. The width | variety of the sheet | seat material T is about 130 mm, and the size of one sheet | seat material T becomes about 200 mm x about 130 mm by cutting | disconnecting with the cutter 14. As shown in FIG. The cut sheet material T is guided by the guide 18 and proceeds downward to pass through the vicinity of the nozzle 25. At this time, cold water or hot water is sprayed from the nozzle 25 toward the sheet material T. The wet sheet material T is guided to the guide 19 and proceeds downward again to reach the guide 36 of the wet wipe drying apparatus 30 as shown in FIG. 5A.

When the sheet material T reaches the guide 36, the motor 31 rotates so that the endless belt 45 starts to rotate in the direction of the arrow b. And the sheet | seat material T is guide | induced by the guide 36, it contacts with the endless belt 45, and it starts to convey in the direction of arrow c by the belt surface 45a of the endless belt 45. When the sheet member T comes in contact with the contact surface 37a of the fixing belt 37, the endless belt 45 is lifted by the thickness of the sheet member T [arrow d], and the sheet member T is endless. The weight of the belt 45 or the like is applied to generate a friction force with the fixing belt 37. And if the sheet | seat material T further advances, it will be conveyed by the belt surface 45a, and will turn by the friction with the contact surface 37a, so that the front-end | tip part may show a contact surface 37a as shown to FIG. 5B and 6A. ) To the side [arrow e]. In addition, when the sheet member T proceeds in the direction of the arrow c, the rolling work further proceeds (FIG. 6B), and is completely dried in a rod shape as shown in FIGS. 6C and 7. At this time, the loosening of the belt surface 45a is increased or the endless belt 45 itself is lifted up, and the sheet member T proceeds in the direction of the arrow c while maintaining an appropriate frictional force.

According to the thickness of the sheet material T, the endless belt 45 is lifted in the direction of the arrow d, or the loosening of the endless belt 45 changes appropriately, so that the endless belt 45 can be rolled regardless of the thickness of the sheet material T. . For this reason, even when the sheet | seat material T which differs in thickness from another material is rolled, it becomes possible to roll about the same degree without adjusting the position of the endless belt 45 and the fixed belt 37 for every sheet | seat material T. In addition, once the endless belt 45 or the like is designed with an appropriate weight, it is not necessary to adjust the contact pressure between the belt surface 45a and the contact surface 37a during assembly, thereby reducing the labor of assembly.

In addition, as the shaft 43 is axially supported by the contact member 35, as the sheet material T in the dried state approaches the driven roller 44, the ratio at which the endless belt 45 is lifted is increased. Since the degree of freedom of the distance between the belt surface 45a and the contact surface 37a is reduced, and a strong frictional force is generated, it is possible to provide a hardly wiped towel so as to be easy to handle without being released at the moment of holding by hand.

Further, by forming a predetermined interval between the belt surface 45a and the contact surface 37a near the driven roller 44, the thick sheet material T is not blocked between the belt surface 45a and the contact surface 37a. It is discharged smoothly.

In addition, as shown in FIG. 8, the elasticity modulus of the contact surface 37a near the driven roller 44 is raised to form the elastic portion 37b, so that the sheet member T in the dried state sinks into the elastic portion 37b. The thick sheet material T is smoothly discharged without being blocked between the belt surface 45a and the contact surface 37a. In addition, the elastic portion 37b can be realized by providing a deep groove in the fixing belt 37 or by using a rubber material of a softer material.

In addition, in the embodiment, the endless belt 45 is pivotably connected to the contact member 35 by axially supporting the shaft 43 on the standing portions 35b and 35c of the contact member 35, and thus the endless belt 35. The contact surface 37a and the belt surface 45a are in contact with each other in a horizontally laid state. However, the present invention is not limited to this structure, and the contact member 35 may be mounted on the endless belt 45 so that the contact surface 37a and the belt surface 45a come into contact with each other by the weight of the contact member 35. Once the contact member 35 is designed with an appropriate weight, it is not necessary to adjust the contact pressure between the belt surface 45a and the contact surface 37a during the assembly, thereby reducing the labor of the assembly. In addition, when the sheet member T becomes thicker and comes close to the driven roller 44, the degree of freedom of the distance between the belt surface 45a and the contact surface 37a decreases and a strong frictional force is generated. It can be provided with a hard, dry towel for easy handling.

According to the wet wipe drying apparatus according to claim 1, since the contact surface is disposed to face the belt surface of the endless belt of the endless belt due to the feeding of the driving roller, the relaxation of the belt surface is appropriately changed by the thickness of the sheet material, and the sheet material is referred to. Can be. For this reason, it is possible to roll a sheet material irrespective of the thickness of a sheet material.

According to the wet wipe drying apparatus according to claim 4, since the endless belt is mounted on the contact member so that the belt surface and the contact surface come into contact with each other by the weight of the endless belt, once the endless belt is designed with an appropriate weight, the belt surface and the contact surface It is not necessary to adjust the contact pressure of the assembly during assembly, thereby reducing the labor of assembly.

According to the wet wipe drying apparatus according to claim 5, the endless belt is pivotably connected to the contact member by supporting the shaft of the driven roller at the end of the contact member, and the contact surface and the belt surface are in contact with the endless belt horizontally laid down. Due to the weight of the belt, an appropriate frictional force is generated and the sheet material can be rolled up. At the same time, when the sheet material becomes thicker and close to the driven roller, the distance between the belt surface and the contact surface becomes smaller, resulting in a stronger friction force, which provides a hardly wiped wipe so that it is easy to handle without being released at the moment of hand holding. Can be.

According to the wet wipe drying apparatus according to claim 6, the contact member is mounted on the endless belt and the contact surface and the belt surface are brought into contact with each other by the weight of the contact member.
