Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device with an alignment mechanism capable of aligning and winding a long object such as a rope, an electric wire or a hose on a winding drum.

[0002]

2. Description of the Related Art In general, a hose used at home, which is longer than 5 meters, uses a winding device having a structure in which a winding drum is used to facilitate storage. The winding device includes left and right support legs, a winding drum provided on the support legs via a rotary shaft, an operation handle provided on one end of the rotary shaft, and a control handle provided on the other end of the rotary shaft. And a handle provided over the upper end of the support leg. Then, when the watering is over, while operating the operating handle with one hand, the hose is guided with the other hand, and the current state is that the hose is distributed equally to the winding drum left and right and wound. .

[0003] Further, depending on the place where the rope is used, the rope or the like may be sent out from the winding drum or used for winding. For example, when hoisting a ship's anchor, if the anchor is small, a rope is used, but when winding the rope around a winding drum, the rope is pulled up using the weight pulled. It is structured so that it is evenly wound around the drum. The winding drum is configured to rotate by driving a motor.

[0004] Further, the reel of the fishing tackle, in order to wind the line almost uniformly around the liner, fixes the guide for the line and moves the liner up and down with respect to the rotation axis so that the thickness around which the line is wound is even. It is configured to be wound in a state of crossing over the bobbin.

However, the conventional means for winding a long object such as a hose has the following problems.

[0005] Since the winding device such as a hose moves the hose so that the hose is evenly wound around the winding drum by using a hand as a guide, the hands become dirty and a heavy burden is imposed on an operator. Note that a tubular body made of vinyl or the like, such as a hose, has a large elasticity unlike a rope or the like.

[0006] In the case of a structure in which a long object is wound evenly by utilizing the pulling weight, the long object cannot be always wound around the winding drum in a constant state, and the long object weighs a predetermined amount or more. If it was not pulled, it could not be wound up evenly.

[0007] A configuration in which the winding drum moves up and down with respect to the rotation axis can be applied if the configuration of the winding drum is small.
When the winding drum is large, the moving distance is large, which is inconvenient.

The present invention has been made in view of the above problems, and provides a winding device with an alignment mechanism that can accurately align and wind a long object such as a hose or a rope with a simple configuration. The purpose is to do.

[0009]

In order to achieve the above object, the present invention relates to a winding drum for winding a long object such as a rope or a hose, a rotating shaft of the winding drum, and the rotating shaft. Left and right supporting portions for rotatably supporting the motor, a drive transmission unit driven to rotate by rotation of the rotation shaft, a drive gear unit operated by the rotation drive of the drive transmission unit, and rotation of the drive gear unit A rotating plate provided on the support shaft, an operating arm provided on the rotating plate, an operating arm provided on the distal end of the operating arm, and a guide holding portion for guiding the long object provided on the distal end side of the operating arm; And a holding unit that rotatably holds a predetermined position of the operation arm, to constitute a winding device with an alignment mechanism.

The rotating plate is formed as a symmetrical cam having a convex portion at one end and a concave portion at the other end, and operates the base end side of the operating arm along the contour of the cam. Alternatively, a configuration may be adopted in which an elastic member that constantly biases the operating arm toward the contour of the cam is provided.

Further, the guide holding section is provided with a moving section which moves left and right along a rail provided over the left and right supporting sections on the distal end side of the operation arm, and the moving section is provided on the side thereof. It is convenient to adopt a configuration in which a guide plate for guiding a long object to be wound is rotatably suspended.

The drive gear unit is a winding device with an alignment mechanism, wherein the gear ratio is determined according to the number of windings of a long object to be wound.

, An operation arm 8 driven by the operation arm 7, and a guide holding portion 9 provided at a tip end side of the operation arm 8.

The support portions 2 are formed in a substantially U-shape (pipe in the drawing) by a metal or synthetic resin pipe or plate material, and each of the mounting portions 2 supports a rotating shaft 3.
a and 2a are attached. Further, the support portion 2,
A handle 2b is provided on the upper end side of the handle 2 and a holding portion 2c is attached to a central portion of the handle 2b.
In addition, a reinforcing support portion 2 provided at a position close to the grounding surface of the support portions 2 and 2 so as to extend over the support portions 2 and 2 respectively.
d and 2d. The drive belt 6a has one end thereof wrapped around a gear such as a pulley provided at the end of the rotary shaft 3, and the other end of the drive belt 6a is connected to a rotation shaft of an operation gear 6b of the drive gear unit 6 as shown in FIG. It is configured to be hung.

As shown in FIGS. 1 and 2, the drive gear 6 is fixedly supported by a mounting support 2e provided at the upper end of one support 2. The configuration of the drive gear unit 6 includes an operation gear 6b which is wound around the other end of the drive belt 6a and operates by rotation of the drive belt, and a reduction gear 6d which reduces the rotation of the operation gear. It is convenient to use a worm gear and a worm wheel, which can be used even if the gear ratio is large, such as a worm gear and a worm wheel, for the operation gear 6b and the reduction gear 6d. The gear ratio is determined correspondingly. For example, in the case where the hose wound around the winding drum 4 is wound in 12 rows, the gear ratio can be set to 24: 1 worm gear and wheel, so that appropriate hose alignment can be guided. Note that a rotary plate 6c is provided on the rotation shaft of the reduction gear 6d.

As shown in FIGS. 1 and 3, one end of the operating arm 7 is rotatably attached to the peripheral edge of the rotating plate 6c, and the other end is connected to the rear end of the operating arm 8. It is rotatably mounted. The operation arm 8 is rotatably attached to the lower end side of the holding portion 2c of the handle 2b, and the operation of the operation arm 8 causes the position of the holding portion 2c to be a rotation fulcrum in the width direction of the winding drum 4. To the left and right. The guide holding portion 9 provided at the distal end of the operating arm 8 bends the distal end of the operating arm 8 at a predetermined angle to form an annular end, and guides and holds a long object such as a hose. It is inserted through the part 9 and used.

When the long object wound on the winding drum 4 is a hose, it is necessary to feed running water from a water supply source to the hose, and as shown in FIG.
A connection port (not shown) of the connection hose is formed at one end of the rotary drum 4a of the winding drum 4 at a predetermined position.

Next, the operation of the winding device 1 with the alignment mechanism will be described with reference to FIGS. As shown in FIGS. 1 to 3, when the long object used in the winding device 1 with an alignment mechanism is a hose, the hose is sent out from the winding drum 4 and used for watering or the like, and then the hose is wound around the handle 5. When it is rotated in the direction, the rotating shaft 3 of the winding drum 4 rotates, and with the rotation, the drive belt 6a operates to operate the operation gear 6b of the drive gear unit 6. When the reduction gear 6d is rotated by the operation gear 6b, the rotating plate 6c rotates by a predetermined angle,
The operating arm 7 is operated.

Therefore, the operation of the operation arm 7 causes the operation arm 8 to move right and left along the width direction of the winding drum 4 around the rotation supporting portion of the holding portion 2c, and the hose moves to the position of the guide holding portion 9. 3 (a) and (b)
In the order of (c), the winding drum 4 is wound up in order from one end side toward the other end side. Then, the guide holding portion 9 moves again from the other end side of the winding drum 4 toward the one end side (in the order of FIGS. 3C, 3B, and 3A), and these operations are repeated. , The whole hose, the winding drum 4
It is possible to wind up in a state of being aligned.

The rotary plate 6c is set so as to make one rotation when the hose wound on the winding drum 4 is wound from one end to the other end of the winding drum 4 and again from the other end to one end. If the configuration is such that the hose is wound around the width of the winding drum 4 by 15 turns, the rotating plate 6c makes one rotation when the handle 5 rotates 30 times so that the operating gear 6 shown in FIG.
b and the gear ratio of the reduction gear 6d are set (in this case, 30: 1).

The structure of the rotating body and the operating arm as shown in FIGS. 4 and 5 may be adopted. That is, as shown in FIG. 4, the rotating body uses a cam 16, and the drive gear unit 15 uses a worm gear 15a and a worm wheel 15b. Therefore, the other end side of the drive belt 6a is stretched around the rotation shaft of the worm gear 15a. A substantially heart-shaped cam 16 is attached to the rotation shaft of the worm wheel 15b.

As shown in FIG. 4, the operating arm 7B
Is provided with a roller 7a at one end thereof, which is in rolling contact with the side surface of the cam 16. A coil spring 1 as an elastic member is provided before and after the rotation fulcrum of the operation arm 8.
One ends of the coil springs 10 and 10 are fixed, and the other ends of the coil springs 10 and 10 are fixed to the support portions 2 and 2, so that the roller 7 a of the operation arm 7 B always contacts the cam 16.

Therefore, when the handle 5 is rotated and the winding drum 4 is rotated in the direction in which the hose is wound, FIG.
As shown in (a), (b), and (c), the rotation of the drive belt 6a rotates the worm gear 15a of the drive gear unit 15, and rotates the worm wheel 15b by a predetermined angle, thereby rotating the cam 16 by a predetermined angle. Let that cam 1
The operation arm 7B is operated by pushing the roller 7a in contact with the profile side surface of the actuator 6. When the operation arm 7B is operated, the operation arm is moved right and left and the guide holding portion 9 guides the winding position of the hose to be wound, so that the hose can be accurately aligned with the winding drum and wound. Becomes

As shown in FIG. 5A, when the roller 7a of the operating arm 7B is in contact with the position of the convex portion 16a of the cam 16, the coil springs 10, 10 are in the most contracted state, and the operating arm 7B is the operating position farthest from the rotation axis position of the cam 16. Then, as shown in FIG. 5C, the operating arm 7 is located at the position of the concave portion 16 b of the cam 16.
When the B roller 7a is in contact, the coil spring 1
0 and 10 are in the most extended state, and the operation arm 7B is in the operation position closest to the rotation axis position of the cam 16.
The operation arm 8 moves left and right along the width direction of the winding drum 4 by operating according to a difference in movement of the operation arm 7B. Then, by configuring the gear ratio of the worm gear 15a and the worm wheel 15b to correspond to the number of windings of the long object of the winding drum 4, a long object such as a hose can be reliably and uniformly applied to the winding drum 4. It becomes possible to take up.

Next, another embodiment of the guide holding unit and the operation arm will be described. The same members are denoted by the same reference numerals. As shown in FIGS. 6 and 7,
The operation arm 18 has an engagement slide portion 18a formed so as to be rotatable at the base end side of the holding portion 2c and bifurcated at a constant interval at the tip end side.

Further, the guide holding portion 25 is provided with rails 19, 19 provided so as to extend over the support portions 2, 2, a moving portion 20 moving along the rails 19, 19, and an upper end of the moving portion 20. An engaging portion 21 protruding to the side, and guide plates 22 and 2 rotatably provided on the side surface of the moving portion 20.
And 2. And the operation arm 18
Of the engaging slide portion 18a of the moving portion 20
When the operating arm 18 is actuated, the engaging portion 21 slides on the forked portion and moves while being held by the engaging slide portion 18a. At this time, the moving unit 20 is configured to move left and right along the rails 19, 19.

Further, a guide plate 2 provided on a side surface of the engagement portion
Since the guide plates 22 and 22 are provided rotatably, even if the diameter of the hose guided by the guide plates 22 and 22 in the wound state increases, the guide plates 22 and 22 are indicated by imaginary lines in FIG. As shown, it is possible to guide the hose in a state where the hose is rotated by a predetermined angle.

Therefore, as shown in FIGS. 7A, 7B and 7C, when the winding drum is rotated by operating the handle 5, the rotation of the rotation shaft 3 of the winding drum 4 causes the drive belt to rotate. The operating arm 7 is operated by rotating the rotating portion 6a at a predetermined gear ratio by rotating the gear portion 6b by rotating the gear 6a (see FIG. 2). As shown in FIGS. 7A and 7B, when the operation arm 7 is operated, the operation arm 8 moves around the position of the rotation fulcrum, and engages with the slide engagement portion on the distal end side of the operation arm 8. Moving part 20 is
Along one side from one end to the center.

As shown in FIG. 7 (b), when the rotating plate 6c is rotated 45 degrees from the position of FIG. 7 (a) by the drive gear unit 6, the moving unit 20 is moved in accordance with the rotation and shown in FIG. As described above, the guide plates 22 and 22 guide the hose so that the hose is evenly wound around the winding drum 4.

Further, from the position of FIG.
Is moved from the central position of the winding drum 4 to the other end side along the rails 19 by the operation of the operation arm 18 until the guide plate 22 guides the hose in order. 4 so that the winding drum 4 can be aligned to wind the hose. When the diameter increases due to the number of windings of the hose wound on the winding drum 4, the guide plates 22, 22 come into contact with the wound hose. Since it is rotatably provided, the hose can be rotated by a predetermined angle as shown by the imaginary line in FIG. 6, and the hose can be properly guided without any problem even if the number of turns is large.

The structure of the rotary plate shown in FIGS. 6 and 7 is the same as that of the cam shown in FIG. 4, and the elastic member is provided so that the roller provided at the base of the operating arm always comes into contact with the contour of the cam. A configuration in which a coil spring is provided may be used. Further, in the winding device with the alignment mechanism having the above-described configuration, the configuration in which the winding drum is manually rotated has been described. However, when the configuration of the long object is a rope,
Since the length of the rope may be tens of meters or more than one hundred meters, the winding drum may be rotated by a drive motor.

Although the drive belt 6a is used as the drive transmission unit, a transmission gear is mounted on one end of the rotation shaft,
A drive gear that meshes with the transmission gear and changes the direction of the rotation shaft by 90 degrees may be provided, and a rotation plate 6c may be provided at one end of the rotation shaft of the drive gear. In addition, it is convenient to provide a support fixing portion for rotatably supporting the rotation shaft of the drive gear as necessary. further,
When a cam is used, a rubber-like member may be used instead of the coil spring as the elastic member.
