  In the present invention, as will be described later, it is possible to attach a well-known wrapping means for wrapping the automatically generated hand towel O with a plastic film or the like. By attaching this wrapping means, the towel T can be wound from folding. Through the formation of the hand towel O, the package of the wound hand towel O can be automatically generated consistently.

  Hereinafter, the conveyance folding part 1 and the winding hand towel forming part 2 which constitute the automatic winding hand towel generator A according to the present invention will be described in detail.

  First, the conveyance folding part 1 is comprised from the towel conveyance means 11 and the towel folding means 12, as mentioned above. The towel conveying means 11 includes a first belt conveyor 111 having a predetermined length provided with the same height and the upper running surface running in the same conveying direction (downward in FIGS. 1 and 2). It comprises a second belt conveyor 112 having a longer conveying length than the belt conveyor 111. First end portions 1111 and 1121 are aligned with the first transport surface 111a that is the upper traveling surface of the first belt conveyor 111 and the second transport surface 112a that is the upper traveling surface of the second belt conveyor 112. .

  Any one of the aligned start end portions 1111 and 1121 is provided with a mark M for transporting the towel T and forming a folded towel O1 having both ends aligned. This mark M forms a folded towel O1 with both ends aligned, so that the portion T1 of the towel T placed on the first belt conveyor 111 by the width in the vertical direction of the second belt conveyor 112 is the second belt. It is guided so as to be wider than the portion T2 of the towel T placed on the conveyor 112. That is, the relationship between the portion T1 and the portion T2 of the towel T is that the width is T1> T2, and the width direction central portion of the towel T is the first when the towel T is placed on the start end portions 1111 and 1121. It is located on the belt conveyor 111. Further, in the present embodiment, the mark M is provided on the second belt conveyor 112 by drawing a straight line in the transport direction. For example, the mark M is provided on any of the aligned start end portions 1111 and 1121. It can be provided by an appropriate means such as a rod-like member that is fixed and provided so as not to affect the running of the motor.

  As shown in FIGS. 4 and 5 in addition to FIGS. 1 to 3, the towel folding means 12 protrudes because the transport length of the second belt conveyor 112 is longer than that of the first belt conveyor 111. A third belt conveyor 121 is provided below 112L. In the third belt conveyor 121, the conveyance direction of the third conveyance surface 121a which is the upper running surface is the same as the conveyance direction of the first conveyance surface 111a, and from the start end portion 1211 of the third conveyance surface 121a. As it goes to the end portion 1212, it is provided so as to rotate in a direction approaching the upper second belt conveyor 112. Further, on the second conveying surface 112a of the second belt conveyor 112 and above the starting end portion 1211 of the third belt conveyor 121, the portion T2 of the towel T being conveyed is placed on the second conveying surface. A pressing roller 122 is provided to press to 112a.

  In particular, the third belt conveyor 121 is provided such that the start end portion 1211 is inclined with respect to the second belt conveyor 112, and in particular, is inclined so that the side closer to the first belt conveyor 111 is positioned above the side farther from the first belt conveyor 111. ing. Further, the end portion 1212 of the third transport surface 121a is substantially parallel to the second belt conveyor. In addition, it is preferable that the start end part 1211 of the 3rd conveyance surface 121a is shifted and provided in the 1st belt conveyor 111 side below the site | part 112L which the 2nd belt conveyor 112 protrudes. This is because it is convenient to transport the portion T1 of the towel T suspended from the second belt conveyor 112 on the third transport surface 121a. For example, as shown in FIGS. 3 and 5, the third belt conveyor 121 and the second belt conveyor 112 are disposed above the substantially central portion in the width direction of the inclined start end portion 1211 of the third transport surface 121a. Exemplifying that the inclined first end portion 1211 of the third conveyance surface 121a is shifted to the first belt conveyor 111 side so that the first belt conveyor 111 side end portion of the belt conveyor 112 is positioned approximately. Can do. In this case, when the portion T1 of the towel T is transported on the third transport surface 121a, wrinkles or the like can be prevented from being formed.

  In addition, the inclination of the start end portion 1211 of the third transport surface 121a is 45 degrees with respect to the horizontal plane in the present embodiment. Along with the formation of this inclination, the pulleys P1 and P2 that constitute the start end portion 1211 of the third transport surface 121 have different diameters. Specifically, the pulley P1 located above the tilted start end portion 1211 has a larger diameter than the pulley P2 located below. Thereby, the start end portion 1211 of the third transport surface 121a is inclined with respect to the second belt conveyor 112, and the bending of the belt caused by the end portion 1212 being provided substantially in parallel is suppressed.

  In this embodiment, when the inclination of the start end portion 1211 of the third transport surface 121a that is 45 degrees with respect to the horizontal plane is a gentle angle (45 degrees or less), the difference in diameter between the pulleys P1 and P2 is When the angle is reduced to a steep angle (45 degrees or more), the difference between the diameters of the pulleys P1 and P2 is increased to provide adjustment so as to suppress the bending of the belt.

  In the transport folding unit 1, the towel T is unfolded so as to straddle the start end 1111 of the first transport surface 111a and the start end 1121 of the second transport surface 112a, and along the mark M on the second belt conveyor 112. The towel T thus placed is transported to reach the projecting portion 112L of the second belt conveyor 112, and the portion T1 placed on the first transport surface 111a of the towel T is transported second. It hangs down from the surface 112a. Subsequently, the portion T1 of the hanging towel T is transported on the third transport surface 121a whose start end portion 1211 is inclined so that the side located near the first belt conveyor 111 is positioned upward, It reaches the end portion 1212 substantially parallel to the two-belt conveyor. Then, in the vicinity of the tip of the terminal end 1122 of the second transport surface 112a, a portion T1 of the towel T transported by the third transport surface 121a and a portion T2 of the towel T transported by the second transport surface 112a Are folded, and a two-fold hand towel O1 is formed.

  In addition, in the conveyance folding part 1, it can form along the mark M on the 2nd belt conveyor 112, and can form the double fold with which both ends were equal. The portion T1 of the towel T that is suspended is transported on the third transport surface 121a in which the start end portion 1211 is shifted to the first belt conveyor 111 side and the belt is prevented from being bent. The formation of wrinkles or the like in the portion T1 can be prevented. Further, on the second conveying surface 112a of the second belt conveyor 112 and above the starting end portion 1211 of the third belt conveyor 121, the portion T2 of the towel T being conveyed is placed on the second conveying surface. Since the pressing roller 122 that presses against the 112a is provided, it is possible to prevent the towel T from dropping due to the portion T1 being pulled by the third conveying surface 121a. Thereby, in the conveyance folding part 1, the both folds hand towel O1 in which both ends are aligned and a wrinkle etc. are not formed can be formed.

  Next, the winding hand towel forming unit 2 includes the tip bending means 21 and the hand towel winding means 22 as described above. In addition to FIGS. 1 to 3, in particular, as shown in FIG. 6, the front end bending means 21 is provided in the vicinity of the front end of the end portion 1122 of the second belt conveyor 112 and the end portion 1212 of the third belt conveyor 121, A guide roller 211 that guides the formed folded hand towel O1 by winding it around a circumference 211a, and the rotation of the guide roller 211 is not affected by the rotation of the guide roller 211 on the circumference 211a. The guide plate 212 is provided at an acute angle and is in contact with the tip O1T of the folded towel O1 guided by the guide roller 211.

  The guide roller 211 is a roller that rotates about an axis. The guide roller 211 is provided with an appropriate friction surface on the circumference 211a in order to guide the wound folding hand towel O1 around the circumference 211a. The driving force for rotation of the guide roller 211 is supplied from the fourth belt conveyor 221 as will be described later. Further, the guide plate 212 is a rectangular plate-shaped member, and is provided without being affected by the rotation of the guide roller 211. The folded towel O1 is wound around the circumference 211a of the guide roller 211 and guided. The tip O1T comes into contact therewith, and the folded towel O1 is prevented from moving further on the circumference 211a of the guide roller 211. Furthermore, since the guide plate 212 is provided at an acute angle with respect to the traveling method of the guide roller 211, the abutted tip O1T is bent toward the circumference 211a of the guide roller 211.

  The hand towel hoisting means 22 is provided so as to oppose the terminal end 1122 of the second belt conveyor 112 via the guide roller 211 and in contact with the guide roller 211 in order to give a driving force to the guide roller 211. The fourth belt conveyor 221 can be sandwiched between the fourth belt conveyor 221 with the conveying direction of the fourth conveying surface 221a, which is a surface in contact with the two-folded towel O1 guided by the guide roller 211, downward, and the fourth belt conveyor 221. The fifth belt conveyor 222 is set at a position opposite to the fourth conveying surface 221a with the conveying direction of the fifth conveying surface 222a, which is a surface in contact with the double folded towel inserted between the fourth belt conveyor 221 and the fourth conveying surface 221a. It consists of. In particular, the transport speed of the fourth transport surface 221a (the running speed S4 of the fourth belt conveyor 221) is faster than the transport speed of the fifth transport surface 222a (the running speed S5 of the fifth belt conveyor 222). In other words, the transport speed of the fourth transport surface 221a is controlled to be four times faster than the transport speed of the fifth transport surface 222a.

  In the hand towel hoisting means 22, the fourth belt conveyor 221 and the fifth belt conveyor 222 sandwich the folded hand towel O1, the transport direction of the fourth transport surface 221a is downward, and the transport direction of the fifth transport surface 222a is the same. By setting it upward, a rotational force in one direction (counterclockwise in FIG. 5) is applied to the folded towel O1 sandwiched between the fourth transport surface 221a and the fifth transport surface 222a. In addition, since the transport speed of the fourth transport surface 221a is four times faster than the transport speed of the fifth transport surface 222a, the folded towel O1 is transported downward while being wound up by the applied rotational force. It becomes like this.

  In addition, the running speed S4 of the fourth belt conveyor 221 that is the conveying speed of the fourth conveying surface 221a is controlled to be less than twice the running speed S5 of the fifth belt conveyor 222 that is the conveying speed of the fifth conveying surface 222a. If this is the case, it is not preferable because it is difficult to convey the folded hand towel O1 in the middle of winding up downward, and if S4 is controlled to be 5 times or more of S5, it can be rotated appropriately with respect to the folded towel O1 in the middle of feeding downward. Since it becomes difficult to give force, it is not preferable. Further, by controlling S4 to about 3 to 4 times S5, it is possible to generate the wound towel O with a high yield.

  In the wrapping hand towel forming portion 2, the two-fold hand towel O 1 formed in the vicinity of the tip of the second belt conveyor 112 is guided by the guide roller 211, and then the tip O 1 T is brought into contact with the guide plate 212, On the circumference 211a of the guide roller 211, the guide roller 211 does not advance further than the guide plate 212 and is bent toward the circumference 211a. As a result of this folding, the folding hand towel O1 is given an opportunity to roll up. Further, the double-folded hand towel O1 to which the hoisting action is given is sandwiched between the fourth transport surface 221a and the fifth transport surface 222a, and is transported downward while being given a rotational force, and is rolled up and rolled up into a cylindrical shape. O.

  More specifically, since the driving force of the guide roller 211 is supplied by the fourth belt conveyor 221 in the winding hand towel forming unit 2, it is folded in two in the end portion 1122 of the second belt conveyor 112 formed near the tip. The hand towel O1 can be guided as it is by the rotation of the guide roller 211. Further, the direction in which the tip O1T is bent toward the circumference 211a by the guide plate 212 coincides with the direction in which the folding towel O1 is sandwiched between the fourth transport surface 221a and the fifth transport surface 222a and is given a rotational force. For this reason, in the winding hand towel forming unit 2, the bending to the circumference 211 a side of the tip O 1 T at the tip bending means 21 is given as an opportunity to wind up. By applying the rotational force, the two-fold hand towel O1 can be reliably rolled up, and the cylindrical hand towel O can be formed.

  Here, in this embodiment, the 1st belt conveyor 111, the 2nd belt conveyor 112, the 3rd belt conveyor 121, the 4th belt conveyor 221, and the 5th which comprise the conveyance folding part 1 and the winding hand towel forming part 2 are demonstrated. The belt conveyor 222 is rotated by a single drive motor. At that time, by adjusting the gear ratio, etc., the running speed of the first belt conveyor 111 is S1, the running speed of the second belt conveyor 112 is S2, the running speed of the third belt conveyor 121 is S3, When the turning speed of the 4-belt conveyor 221 is S4 and the turning speed of the fifth belt conveyor 222 is S5, control is performed so that the relational expression of S3 = S4> S1 = S2> S5 is satisfied, and S4 is It is controlled to be 2 to 5 times S4 (4 times in the present embodiment).

  As a result, a series of operations for folding the towel T in two and further rolling up the two-folded towel O1 to generate the wound towel O becomes smooth, and the automatic hand towel generator A with high yield is achieved. Note that unless S1 = S2, the towel T will not be conveyed while being unfolded, which is not preferable. The reason why S3> S2 is based on the fact that the third belt conveyor 121 is provided obliquely with respect to the second belt conveyor 112. The reason why S3 = S4> S2 is that it is convenient for guiding the double folded towel O1 formed in the vicinity of the front end of the second belt conveyor 112 by the rotation of the guide roller 211 as it is. .

  In addition, in the present embodiment, when the towel T is placed along the mark M provided on the second belt conveyor 112, the towel is placed on the first belt conveyor 111 by the width in the vertical direction of the second belt conveyor 112. By making the portion T1 of the towel T to be placed wider than the portion T2 of the towel T placed on the second belt conveyor 112, it is possible to form a double folded towel O1 with both ends aligned. . In the present invention, the practitioner unfolds the towel T so as to straddle the start end portion 1111 of the first transfer surface 111a and the start end portion 1121 of the second transfer surface 112a, and the mark M on the second belt conveyor 112. , The towel T is folded in half, and the folded hand towel O1 is wound up to complete a series of operations for generating the wound towel O.

  Thus, in the present invention, by being configured as described above, the towel T is developed so as to straddle the start end portion 1111 of the first transfer surface 111a and the start end portion 1121 of the second transfer surface 112a, and With the operation of only placing on the second belt conveyor 112 along the mark M, the placed towel T is transported to the projecting portion 112L of the second belt conveyor 112, and the first transport of the towel T is performed. The portion T1 placed on the surface 111a hangs down from the second transport surface 112a, and the portion T1 of the suspended towel T is transported on the third transport surface 121a, and the end portion 1122 of the second transport surface 112a. In the vicinity of the tip, the portion T1 of the towel T conveyed by the third conveying surface 121a and the portion T2 of the towel T conveyed by the second conveying surface 112a are folded and folded in two. It is possible to form a hand towel O1. Further, the folded hand towel O1 is guided as it is by the guide roller 211 provided in the vicinity of the terminal end 1122 of the second belt conveyor 112, the tip O1T is brought into contact with the guide plate 212, and is folded toward the draft circumference 211a. In a state where the bending and the winding up by the bending are applied, the sheet begins to be conveyed downward by the fourth conveying surface 221a, and is sandwiched between the fourth conveying surface 221a and the fifth conveying surface 222a and is given a rotational force. Since it is transported downward and rolled up to become a cylindrical wound towel O, it is possible to automatically generate the wound towel O. Therefore, the practitioner can automatically generate the folding hand towels efficiently regardless of the proficiency level, and can automatically generate the winding hand towels O.

  Further, the rotation speed of the first belt conveyor 111 constituting the conveyance folding unit 1 and the winding hand towel forming unit 2 is S1, the rotation speed of the second belt conveyor 112 is S2, and the rotation of the third belt conveyor 121 is When the speed is S3, the running speed of the fourth belt conveyor 221 is S4, and the running speed of the fifth belt conveyor 222 is S5, control is performed so that the relational expression of S3 = S4> S1 = S2> S5 is established. And S4 is controlled to be four times S5. As a result, the series of operations for folding the towel T in two and further rolling up the two-folded hand towel O1 to generate the wound hand towel O becomes smooth, and the automatic hand-wiping towel generator A with higher yield is achieved.

  In addition, in the automatic hand towel application generator A according to the present invention, a packaging means such as a well-known hand towel wrapping device is provided below the fourth belt conveyor 221 where the hand towel O is formed (near the end portion of the fourth conveying surface 221a). Can be installed. Specifically, a packaging means is provided so that a plastic film surface for receiving the winding hand towel O of the packaging device is provided below the fourth belt conveyor 221, and the winding hand towel O formed below the fourth belt conveyor 221 is provided. Take it and pack it.

  In the above embodiment, for convenience, a mode has been described in which a single hand towel O is automatically generated from a single towel T on a single device. For example, a towel is placed at a predetermined position every few seconds. Therefore, it is possible to perform high-speed processing in which a single hand-roller forms a series of hand towels one after another, and the human burden during the busy season can be greatly reduced.

  As mentioned above, although one Embodiment of this invention was illustrated and explained in full detail, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims. For example, in the above embodiment, an example in which the number of drive motors is one and the rotational speeds of the first belt conveyor to the fifth belt conveyor are controlled by a gear ratio or the like has been described. However, for the convenience of controlling the rotational speed, the drive motor is described. It is good also as multiple. In addition, a belt, a pulley, a pressure roller, a guide roller, a guide plate, and the like constituting the belt conveyor may be made of known materials and known means.
