Description

  The present invention relates to a ridge sheet winding device that winds a ridge sheet used in a paddy field in a roll shape.

  In paddy rice cultivation, it is important to fill the paddy with water, and ridge sheets are often buried for the purpose of reinforcing the water stopping function by the ridges and preventing water leakage from the holes opened by small animals. This ridge sheet is generally dug up after paddy rice cultivation is finished and wound up in a roll form for reuse in the next year and stored. However, long ridge sheets are as long as 20 m to 50 m. There is a great deal of labor to wind up manually. Further, when the roll-up of the ridge sheet is loosely wound, the roll-shaped state may be broken when lifted. For this reason, it is necessary to wind while tightening with a certain strength, and it is also a burden for the operator to use considerable arm strength for that purpose. In order to improve such a situation, there are known ridge sheet winding devices that attempt to reduce the labor for winding the ridge sheet (for example, see Patent Documents 1 to 3).

  The ridge sheet winding devices described in Patent Documents 1 to 3 include a winding portion for winding the ridge sheet, and a crank handle or a handle having a similar function attached to the winding portion. An operator using these winding devices can wind one end of the ridge sheet in the longitudinal direction on the winding portion and turn the handle to wind the ridge sheet around the winding portion. By doing so, the effort to wind up the ridge sheet is reduced as compared with the case of winding up manually.

  However, in some cases, it is necessary to wind up a large amount of ridge sheets, and in the ridge sheet winding devices described in Patent Documents 1 to 3, the operation of turning the handle still imposes a heavy burden on the operator. In particular, the work of winding while tightening so that the rolled state does not collapse when lifted or the like still requires a corresponding arm strength, and thus further improvement for reducing the work labor is desired.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ridge sheet winding device capable of greatly reducing the work labor.

It may be provided. Further, the winding section may wind a ridge sheet having a shape continuous in a wavy shape in the longitudinal direction .
According to the above-described ridge sheet winding device, since the power device for rotating the winding portion is provided, the worker does not need to rotate the handle to wind the ridge sheet, and the labor of the work is greatly reduced. Can be reduced. Further, for example, by slightly pulling the ridge sheet, the ridge sheet can be wound while being tightened on the winding section rotated by the power machine. This makes it easy to wind up the ridge sheet so that the rolled state does not collapse when lifted.

In the above ridge sheet winding device, the winding portion extends in a width direction of the ridge sheet to be wound, and a winding core around which the ridge sheet is wound, and an extending direction of the winding core. And a flange-shaped regulating plate that contacts one end of the rolled-up ridge sheet in the width direction to align the position of the ridged sheet. Is preferably slidable to the other side in the extending direction of the first member.

  Here, the winding core may have a locking portion that sandwiches one end in the longitudinal direction of the ridge sheet having a shape that is continuous in a wavy shape in the longitudinal direction and locks the one end of the ridge sheet. The locking portion may be a slit extending in the extending direction, or may be one in which two rods are arranged in a bird's beak shape. Further, a second regulating plate may be detachably provided on the other side in the extending direction of the winding core.

  By adopting the mode having the regulation plate, the ridge sheet wound around the take-up core can be easily removed from the take-up core by sliding the regulation plate to the other side.

In addition, in the above-mentioned ridge sheet winding device, a mode in which an arm portion that comes into contact with the regulating plate and slides the regulating plate toward the other side is also one of preferred embodiments.

That is, the upstream front side roller, the downstream front side roller, and the back side roller all rotate while applying the tension to the ridge sheet.

Furthermore, it is preferable that the above-mentioned ridge sheet winding device further includes a cleaning unit that discharges cleaning water toward the passage area.

  Mud is often attached to the ridge sheet dug up and used in paddy fields, especially in corrugated ridge sheets. The mud adhering to the ridge sheet not only hinders the winding of the ridge sheet, but also increases the weight of the ridge sheet and requires extra labor when transporting, and the mud falls down during transport and storage to contaminate the surroundings. Conventionally, before the ridge sheet is wound up, it is rubbed off with a spatula or a brush, or the cleaning water is sprayed with a high-pressure washing machine into the gap between the gently rolled ridge sheet, and the mud is washed. Work such as retightening the ridge-shaped sheet was performed.

  Therefore, if the cleaning section is provided, the mud adhering to the ridge sheet can be removed when passing through the passage area. Thereby, the ridge sheet can be wound up with the mud removed, and the work of retightening the roll-shaped ridge sheet after washing is not required.

Still further, in the above-described ridge sheet winding device, the cleaning unit may discharge the cleaning liquid toward a discharge region through which a widthwise central portion of the unwound portion passes.

  Here, the cleaning unit may discharge the cleaning liquid toward the discharge region from an oblique direction shifted from directly above the discharge region. The winding section may be provided with the ridge sheet so that a portion of the ridge sheet buried in the ground passes through the discharge area. That is, the winding section may wind the ridge sheet in which a portion buried in the ground has passed through the discharge area.

  The cleaning liquid is discharged from the cleaning section toward the discharge area, and the ridge sheet is attached to the winding section such that a portion of the ridge sheet embedded in the ground passes through the discharge area. Thus, the portion of the ridge sheet to which the mud is adhered can be efficiently cleaned.

Still further, in the above-described ridge sheet winding device, the ridge sheet that is wound by the winding unit may include a tilting member that tilts a portion that passes through the passage area downward over the entire width direction of the ridge sheet. The embodiment provided is also one of the preferable embodiments.

  Here, at least one of the front-side regulating member and the back-side regulating member may also serve as the inclined member. Further, a portion of the ridge sheet wound by the winding section, which has passed through the passage area, may be inclined downward over the entire width direction of the ridge sheet.

  If the aspect including the inclined member is adopted, the mud adhering to the ridge sheet can be more efficiently washed away.

  According to the ridge sheet winding device of the present invention, the labor of the work can be greatly reduced.

The ridge sheet winding device according to one embodiment of the present invention digs up a ridge sheet buried in a ridge of a paddy field for the purpose of reinforcing a water stopping function by the ridge, for example, a roll for storing until the next year. It is wound up in a shape. Hereinafter, the ridge sheet wound in a roll shape may be referred to as a ridge sheet roll.

  FIG. 1A is a front view of a ridge sheet winding device 10 according to an embodiment of the present invention, and FIG. 1B is a plan view of FIG. 2A is a view of the ridge sheet winding device 10 shown in FIG. 1A as viewed from the left side, and FIG. 2B is a view of the ridge sheet shown in FIG. 1A. It is the figure which looked at the winding device 10 from the right side. Hereinafter, the ridge sheet winding device 10 may be simply referred to as the winding device 10.

  The ridge sheet wound by the winding device of the present invention is a long sheet made of, for example, vinyl chloride, having a width of about 20 cm to 60 cm and a length of about several meters to 50 m. As the ridge sheet, a flat sheet, a corrugated sheet that is continuous in a wavy shape in the longitudinal direction, or the like is used. FIGS. 1A and 1B show a ridge sheet S wound by the winding device 10. In the present embodiment, a mode in which a corrugated ridge sheet S is wound up as shown in FIG. The ridge sheet S has, for example, a corrugated sheet height H of about 1 cm and a corrugated sheet pitch P of about 3.5 cm.

  In FIG. 1A and FIG. 1B, the long ridge sheet S moves from the left side to the right side of the figure and is wound up. Therefore, in FIGS. 1A and 1B, the left-right direction is the longitudinal direction of the ridge sheet S, the left side is the upstream side in the movement of the ridge sheet S, and the right side is the movement of the ridge sheet S. Downstream. Also, in FIG. 1A, the direction perpendicular to the paper surface is the width direction of the ridge sheet S, and in FIG. 1B, the vertical direction of the figure is the width direction of the ridge sheet S. In FIGS. 2A and 2B, the ridge sheet S is omitted for simplification of the drawing. However, in FIGS. In the width direction of the sheet. In the following description, the direction may be simply referred to as the longitudinal direction or the width direction with reference to the longitudinal direction and the width direction of the ridge sheet S shown in FIGS. 1A and 1B.

  As shown in FIGS. 1 and 2, the winding device 10 has a frame-shaped frame 2 installed on the ground, two rollers 3 installed on the frame 2, and also installed on the frame 2. It has a power unit 4 and a winding unit 5 attached to the power unit 4.

  The winding portion 5 includes a winding core 51 extending in the width direction, and one side in the extending direction of the winding core 51 (a back side in FIG. 1A, an upper side in FIG. (A) has a flange-shaped regulating plate 52 attached to the left side (in FIG. 2 (b), right side). The winding core 51 is a portion to which one end of the ridge sheet S is attached.

  In the part surrounded by the two-dot chain line circle in FIG. 1A, the winding core 51 to which one end of the ridge sheet S is attached is shown in an enlarged manner, and the part surrounded by the two-dot chain line circle, As shown in FIGS. 1B and 2B, the winding core 51 has a round bar 511 and an auxiliary round bar 512 arranged with a slight gap from the round bar 511. I have. The auxiliary round bar 512 has a smaller diameter (for example, about 1/3 to 1/2) and a shorter length than the round bar 511.

  1A, one end of the ridge sheet S is inserted between the round bar 511 and the auxiliary round bar 512, and the electric motor 42 (see FIG. When the take-up core 51 is rotated by driving (see a)), the ridge sheet S is taken up by the take-up core 51 with one end of the ridge sheet S attached to the take-up core 51. That is, in the present embodiment, the round bar 511 and the auxiliary round bar 512 correspond to an example of the locking portion. Here, in order to insert one end of the ridge sheet S between the round bar 511 and the auxiliary round bar 512, the leading end of the ridge sheet S may be inserted between the round bar 511 and the auxiliary round bar 512. The end of the ridge sheet S may be horizontally slid and sandwiched between the round bar 511 and the auxiliary round bar 512 from the side. In addition, the form of the winding core 51 is not limited to the above-described form, and may be a cylindrical or polygonal column in which a slit for sandwiching one end of the ridge sheet S is formed in the extending direction. It may be a hollow pipe. Further, the winding core 51 may be constituted by two rods, and may be provided with a locking portion having a tip portion opened like a bird's beak. In the latter mode, as in the modes shown in FIGS. 1 and 2, one end of the ridge sheet S may be sandwiched between two rods, and the winding operation may be started.

  The restricting plate 52 is configured to prevent one end of the ridge sheet S in the width direction of the ridge sheet S wound on the take-up core 51 from contacting the ridge sheet S so as to prevent the ridge sheet S from shifting in the width direction. 1A, and is formed in a disk shape slightly larger than the ridge sheet roll S ′ indicated by a dashed line in FIG. Here, in the present embodiment, when the winding core 51 is rotated by the electric motor 42, the regulating plate 52 employs a mode in which the regulating plate 52 rotates together with the winding core 51. A regulating plate 52 that does not rotate independently of the core 51 may be employed.

  The power unit 4 includes a box-shaped casing 41, into which the other end of the winding core 51 is inserted. FIG. 2A shows the inside of the casing 41 by removing the side plate 411 of the casing 41.

  As shown in FIG. 2A, a power machine is housed in the casing 41. In the present embodiment, the electric motor 42 is used as the power machine because the operation and the stop need to be easily repeated. The electric motor 42 is preferably a deceleration motor having a low rotation speed and a high torque or a motor with a speed reducer, and more preferably a motor having a variable rotation speed. Note that the power machine is not limited to the electric motor 42, and other configurations that generate rotational driving force, such as an engine, may be used.

  A belt 43 is stretched between a motor pulley 421 attached to the rotating shaft of the electric motor 42 and a pulley 513 attached to the other end of the winding core 51. Thereby, the winding core 51 can be rotated by driving the electric motor 42. Note that, instead of the belt 43, for example, a generally used power transmission member such as a chain or a gear may be used. Here also, it is preferable that the rotation speed of the electric motor 42 be converted into the rotation speed of the winding core 51 suitable for the winding work of the ridge sheet S by appropriately adjusting the pulley diameter and the like. The casing 41 is provided with a switch 44 for switching between operation and stop of the electric motor 42. Further, as shown in FIG. 2B, a small confirmation window 412 for confirming the inside of the casing 41 is formed in the casing 41.

  The two rollers 3 are provided in a posture extending in the width direction. These two rollers 3, 3 are driven rollers that rotate when the unwound portion of the ridge sheet S comes into contact, as described later, and as shown in FIGS. 1 (a) and 1 (b). , Above the ridge sheet S. Here, an area of the ridge sheet S, which is connected to the winding core 51 from an upstream side of the winding core 51 and through which the unwound portion wound by the winding core 51 passes, corresponds to a passing area.

  1A and 1B, in the unrolled portion of the ridge sheet S, the upper surface corresponds to the front surface, and the lower surface corresponds to the back surface. Therefore, the rollers 3, 3 are arranged on the front surface side of the ridge sheet S in the passage area, over the width direction of the ridge sheet S, and the unrolled portion of the ridge sheet S comes off the front surface side. And is equivalent to an example of a front-side regulating member. The rollers 3 and 3 have a function of guiding the rolled sheet 51 to the winding unit 51 while holding down a wound portion passing through the passage area. In the present embodiment, since a plurality of (two in the present embodiment) rollers 3 are installed at regular intervals in the longitudinal direction, the effect of suppressing the shaking of the ridge sheet S to be wound is high and more preferable. Further, the rollers 3 and 3 can adjust the torque by changing the pressure of a built-in spring (not shown) to apply tension toward the upstream side to the passing ridge sheet S. It may be. In the following description, of the two rollers 3, 3 arranged on the front surface side of the ridge sheet S, the upstream roller 3 is referred to as an upstream front roller 31, and the downstream roller 3 Are sometimes referred to as downstream front rollers 32 to distinguish them.

  Next, an operation of winding the ridge sheet S by the winding device 10 illustrated in FIGS. 1 and 2 will be described. First, one end portion of the ridge sheet S is grasped and passed under the rollers 3 from the upstream side to the downstream side. Subsequently, as described above using the portion surrounded by the two-dot chain line circle in FIG. 1A, one end of the ridge sheet S is inserted between the round bar 511 and the auxiliary round bar 512, for example, Then, the switch 44 is operated in a state where one end of the ridge sheet S is slightly bent, and the electric motor 42 shown in FIG. 2A is driven. As a result, the ridge sheet S is wound around the winding core 51 having the round bar 511 and the auxiliary round bar 512, and the unrolled portion of the ridge sheet S moves from the upstream side to the downstream side. . The unwound portion of the ridge sheet S moving from the upstream side to the downstream side is regulated from above by the rollers 3 and 3, and the runaway is suppressed. When the ridge sheet S is completely wound on the winding core 51, the switch 44 is operated to stop driving the electric motor 42. When winding the ridge sheet S, the ridge sheet S wound on the winding core 51 may be pressed by hand so as not to shift in the horizontal direction. As shown by the dashed line in FIG. 1, when the ridge sheet S is wound into a roll, the work is completed by removing the ridge sheet roll S ′ wound into the roll from the winding core 51 to the other side. I do. When the ridge sheet S 'is loosely wound, the other end of the ridge sheet S may be pulled by hand before being removed from the winding core 51.

  In the present invention, since the winding core 51 is rotated by the electric motor 42, there is no need for the operator to rotate the handle for winding the ridge sheet S, and the work labor can be greatly reduced. In addition, by rotating the winding core 51 by the electric motor 42, the ridge sheet S may be wound while tightening the ridge sheet S so that the rolled state does not collapse when the ridge sheet roll S 'is removed from the winding core 51 or the like. Becomes easier. In particular, in the present embodiment, since the rollers 3 that can apply tension to the ridge sheet S toward the upstream side are employed, the ridge sheet S can be wound up while being tightened. By changing the tension applied to the ridge sheet S by 3, it is also possible to adjust the force for tightening the ridge sheet S.

  Next, a modified example of the winding device 10 shown in FIGS. 1 and 2 will be described. In the modified example described below, differences from the embodiment shown in FIGS. 1 and 2 will be mainly described.

  FIG. 3 is a diagram showing a state corresponding to FIG. 2A for a first modification of the winding device shown in FIGS. 1 and 2. Therefore, also in FIG. 3, the left-right direction corresponds to the width direction, the left side is one side, and the right side is the other side. Note that FIG. 3 shows a state in which the side plate 411 of the power unit 4 is attached, different from FIG.

  As shown by the arrow in FIG. 3, in the winding device 11 of the first modified example, the regulating plate 52 is slidable to the other side in the extending direction of the winding core 51. For this reason, by sliding the regulating plate 52 to the other side, the ridge sheet roll S ′ shown by the dashed line in FIG. 3 is slid to the other side as shown by the dashed line in FIG. The work of removing the roll S ′ can be facilitated. Here, when the force for tightening the ridge sheet S is increased so that the roll-shaped state does not collapse, it may be difficult to remove the ridge sheet roll S ′ from the winding core 51. The winding device 11 of the first modified example is an effective mode when it is difficult to remove the ridge sheet roll S ′ from the winding core 51 as described above.

  FIG. 4 is a diagram illustrating a state in which the row sheet roll S ′ is removed in the second modification of the winding device 10 illustrated in FIGS. 1 and 2. Also in FIG. 4, the left-right direction corresponds to the width direction, but most of the power unit 4 and a part of the frame 2 are omitted, and the winding unit 5 is shown as a center. In FIG. 4, the rollers 3 are omitted for simplification of the drawing.

  As shown in FIG. 4A, the winding device 12 according to the second modification includes a second regulating plate 53 and an arm 54. The second regulating plate 53 is provided detachably on the other side in the extending direction of the winding core 51, and sandwiches the ridge sheet S wound around the winding core 51 together with the regulating plate 52, and forms a ridge sheet. S is prevented from shifting in the width direction. The arm 54 is arranged on one side with respect to the regulating plate 52, and can rotate the upper end portion toward the other side around the shaft portion 541 provided at the lower end portion.

  In the winding device 12 of the second modified example, in order to remove the ridge sheet roll S ′ wound around the winding core 51, first, the second regulating plate 53 is removed from the winding core 51, and then, FIG. The arm 54 is rotated to the other side as shown in FIG. By doing so, the regulating plate 52 slides to the other side, and the ridge sheet roll S ′ slides to the other side accordingly. This facilitates the work of removing the ridge sheet roll S ′ from the winding core 51. Can be. According to the winding device 12 of the second modification, the operation of sliding the row sheet roll S 'to the other side can be performed more easily than the winding device 11 of the first modification. The configuration of the arm is not limited to the present embodiment, and a configuration in which the regulating plate 52 is slid to the other side with a small force due to leverage can be appropriately adopted.

  Next, a second embodiment of the winding device of the present invention will be described. In the following description, components having the same names as those of the components described so far will be denoted by the same reference numerals, and duplicate description may be omitted.

  FIG. 5A is a front view of the winding device 13 according to the second embodiment, and FIG. 5B is a plan view of FIG. That is, FIG. 5A is a diagram corresponding to FIG. 1A, and FIG. 5B is a diagram corresponding to FIG. 1B. For this reason, also in FIGS. 5A and 5B, the ridge sheet S moves from left to right and is wound by the winding unit 5, the left side being the upstream side, and the right side being the downstream side. . Also, in FIG. 5B, the upper side corresponds to one side and the lower side corresponds to the other side, as in FIG. 1B.

  As shown in FIGS. 5A and 5B, the winding device 13 of the second embodiment includes a cleaning unit 6 between an upstream front roller 31 and a downstream front roller 32. And a back roller 33 are provided. Thus, from the upstream side to the downstream side, the upstream front roller 31, the cleaning unit 6, the back roller 33, and the downstream front roller 32 are arranged in the stated order. As shown in FIG. 5A, the upstream front side roller 31 and the downstream front side roller 32 of the winding device 13 are connected to the upstream front side of the winding device 10 shown in FIG. It is arranged at a position higher than the side roller 31 and the downstream front side roller 32. In the height direction, a back roller 33 is disposed between the upstream front roller 31 and the downstream front roller 32 and the frame 2. As a result, the unrolled portion of the ridge sheet S has its back surface supported by the back roller 33. Further, the upstream side of the portion supported by the back roller 33 is regulated by the upstream front roller 31 from the front side, and the downstream side of the portion supported by the back roller 33 is viewed from the front side. It is regulated by the downstream front roller 32. The back roller 33 is for regulating the unrolled portion of the ridge sheet S from coming off to the back side, and corresponds to an example of a back side regulating member.

  In addition, the arrangement position and the number of these rollers 3 are not particularly limited, and one front roller 3 may be provided, or a plurality of back rollers 3 may be provided. However, in order to smoothly wind the ridge sheet S around the winding unit 5, the front roller 3 is disposed at the most downstream side, and immediately before being wound by the winding unit 5, from the front side. It is preferable that the ridge sheet S be suppressed from becoming unsteady. Further, the front roller 3 and the back roller 3 may be vertically arranged, and the ridge sheet S may be sandwiched between the front roller 3 and the back roller 3. However, the winding device according to the second embodiment may be used. By arranging the front roller 3 and the back roller 3 at positions displaced in the longitudinal direction as in 13, even the corrugated ridge sheet S can be smoothly moved.

  The cleaning unit 6 removes mud adhering to the ridge sheet S by discharging the cleaning liquid at a high pressure. By winding up the ridge sheet S while removing mud by the washing unit 6, a ridge sheet roll S 'from which mud has been removed can be obtained. As shown in FIG. 5A, the cleaning unit 6 includes a front side nozzle 61 disposed on the front side of the ridge sheet S, and a back side nozzle 62 disposed on the back side of the ridge sheet S. ing. In the present embodiment, tap water is used as the washing liquid, and the washing unit 6 pressurizes tap water supplied from a water supply pipe (not shown) with a pump or the like, and applies high pressure from the front nozzle 61 and the back nozzle 62. It discharges. Specifically, the washing water is discharged from the front side nozzle 61 to a substantially central portion in the width direction on the front surface of the ridge sheet S, and the back side nozzle 62 substantially discharges the back surface of the ridge sheet S in the width direction. Dispense the washing water into the central part. A region where the cleaning water is discharged from the front side nozzle 61 and the back side nozzle 62 corresponds to an example of a discharge region. Further, the cleaning water is discharged from the front nozzle 61 and the back nozzle 62 in a direction obliquely directed from one side to the other side. Thereby, for example, the ridge sheet S is attached to the winding core 51 such that a portion (for example, about several cm to half the length in the width direction) buried in the ground of the ridge sheet S is located on the other side. If this is the case, the portion buried underground and to which mud has adhered can be efficiently cleaned. In addition, as shown in FIG. 5A (omitted in FIG. 5B), in the present embodiment, a splash prevention hood 7 is provided so as to cover the washing unit 6 in order to prevent scattering of muddy water due to washing. Have been.

  Wash water may be discharged from the front nozzle 61 and the back nozzle 62 in a direction crossing the width direction of the ridge sheet S. However, when the corrugated ridge sheet S is used, the cleaning water is discharged in a direction along the width direction of the ridge sheet S as shown in FIGS. 5A and 5B. This is more preferable because mud can flow along the corrugated shape of the ridge sheet S.

  Here, the position where the cleaning unit 6 is disposed is not particularly limited, and may be upstream of the plurality of rollers 3 or immediately before the ridge sheet S is wound by the winding unit 5. Is also good. Further, a mode in which the washing water is discharged to a portion where the ridge sheet S is wound by the winding unit 5 may be adopted. However, if the cleaning unit 6 is disposed between the upstream front roller 31 and the back roller 33 as in the present embodiment, the portion of the ridge sheet S to which the cleaning water is discharged becomes stable. , It becomes possible to wash more efficiently.

  FIG. 6A is a diagram conceptually illustrating a preferred embodiment of the front nozzle 61, the back nozzle 62, the downstream front roller 32, and the back roller 33. In FIG. 6A, the winding device 13 of FIG. 5A is viewed from the left side. In FIG. 6A, the left side is one side and the right side is the other side.

  As shown in FIG. 6A, the downstream front roller 32 and the rear roller 33 are provided in an inclined position so as to face downward toward the other side. It is inclined downward toward the other side over the entire width direction. That is, the downstream front roller 32 and the rear roller 33 correspond to an example of an inclined member. If water is discharged from the front side nozzle 61 in a state where the ridge sheet S is inclined over the entire area in the width direction, the attached mud can be washed away efficiently, and the discharged water can easily flow down. Note that only one of the downstream front roller 32 and the rear roller 33 may be inclined, or the ridge sheet S may be inclined using an inclined member having a configuration other than the roller 3. Note that, particularly on the back surface of the ridge sheet S, the range in which the wash water is discharged tends to be narrow. Therefore, a plurality of back side nozzles 62 may be provided to secure the range in which the wash water is discharged.

  FIG. 6B is a partial plan view of the ridge sheet for explaining the ejection area. FIG. 6A shows a part of the front surface of the ridge sheet S, in which the left side is one side and the right side is the other side. That is, the ridge sheet S shown in FIG. 6B moves from the bottom to the top, and the upper side is the downstream side.

  The portion indicated by hatching of the lower left in the ridge sheet S shown in FIG. 6B is a buried portion, and mud is attached to this portion. In order to efficiently wash the portion to which the mud has adhered, the region indicated by cross-hatching in the ridge sheet S shown in FIG. 6B, that is, the central portion in the width direction of the ridge sheet S, specifically, It is preferable that the washing water be discharged toward one end of the portion where the mud adheres, or toward the one side of the mud where the mud adheres. That is, the area indicated by cross-hatching corresponds to an example of the ejection area. Here, the portion on which the mud adheres varies depending on the ridge sheet S to be wound. However, the front side nozzle 61 and the back side nozzle 62 of the present embodiment can change the discharge area, and the mud adheres. What is necessary is just to adjust the ejection region in accordance with the portion that has been set.

  According to the winding devices 10, 11, 12, and 13 described above, the work labor can be significantly reduced.

  The present invention is not limited to the above-described embodiments, and various changes can be made within the scope described in the claims. For example, in the above-described embodiment, the winding core 51 is rotated around a rotation center extending in the horizontal direction. However, the winding core 51 is rotated in a direction obliquely inclined from the horizontal direction. It is good also as a mode rotated about the center or the rotation center extended in the vertical direction. Further, in the above-described embodiment, the mode in which the drive of the electric motor 42 is stopped by operating the switch 44 is adopted. For example, a sensor is provided on the downstream front side roller 32 or the like, and the sensor is used by this sensor. Control means for stopping the driving of the electric motor 42 when the completion of the winding of S is detected may be provided, or a timer may be provided, and when a predetermined time elapses after the driving of the electric motor 42 is started, Control means for stopping driving may be provided.

  In addition, even if it is a component included only in the description of each of the modified examples and other embodiments described above, the component may be applied to other modified examples and other embodiments.
