Description

  The present invention relates to a long object winding device configured to wind a long object around a drum.

2. Description of the Related Art Conventionally, a long object winding device that stores a long object such as a hose or a cord by winding it on a drum that is rotatably supported by a drum support has been used.
In such a long material take-up device, when a long object is wound by rotating the drum, the long object is likely to be concentrated and taken up at a deviated position (particularly at the end) in the axial direction of the drum. There is.

  In order to solve such a problem, in the hose reel described in Patent Document 1, a holding portion that slidably holds the hose is provided so as to be movable in the axial direction of the drum. According to this configuration, when the hose is wound, an operation for moving the holding portion in the axial direction of the drum is performed, so that the hose can be evenly wound in the axial direction of the drum without getting a hand dirty. However, since the operation of moving the holding unit must be performed in addition to the operation of rotating the drum, the operation becomes complicated. In particular, when winding the hose after passing water, the drum support is easy to move due to the weight of the hose and drag resistance, and it is necessary to perform the winding operation while keeping the drum support from moving. There is a problem in that the hose is disturbed without being able to move well.

On the other hand, the hose reel described in Patent Document 2 has a configuration in which a drum is housed in a rectangular main body case (housing), and an opening through which the hose is inserted is formed on the front surface of the main body case. It becomes the shape which becomes small as the width direction of these goes upwards. With such a configuration, even when the hose is concentrated and wound around the axial end of the drum, the hose is guided to the axial center of the drum by the opening when a predetermined amount is stacked. I have to.

  In general, since the hose is made of rubber or vinyl, the frictional force generated on the outer peripheral surface is large. For this reason, in the configuration like the hose reel described in Patent Document 2, when the hose is wound, a large frictional force is generated at the contact portion between the hose and the opening, and the hose is easily disturbed by this frictional force. There was a problem of becoming. For this reason, in the hose reel described in Patent Document 2, the hose to be used is limited to the outer peripheral surface provided with unevenness extending in the length direction. Since the force could not be reduced significantly, it could not be said to be sufficient to suppress hose turbulence. Such a problem can also occur for long objects other than hoses.

  The present invention has been made in view of these problems, and an object of the present invention is to provide a long object winding device that can effectively suppress the turbulence of a long object.

In order to achieve the above object, a long object winding device of the present invention includes a drum for winding a long object and a drum support that rotatably supports the drum , and the long object is a drum. It is comprised so that it may wind up from below . In addition, the long object winding device includes a holding body that slidably holds a portion of the long object that is not wound on the drum, and a sliding movement of the holding body on a moving path along the axial direction of the drum. And a guide body that supports it. The guide body forms a movement path at a fixed position regardless of the amount of the long object wound around the drum, and the movement path formed by the guide body extends from both ends in the axial direction to the center side. In the state where the winding operation of the long object is being performed, the holding body is inclined in a direction in which the holding body comes into contact with the guide body.

Here, the "direction holding member abuts against the guide member in a state where the winding operation of the long object has been performed" is better below. This is because downward force is applied to the holding body due to gravity applied to the holding body and the long object held by the holding body .

According to the long object winding device having such a configuration, it is possible to effectively suppress the occurrence of turbulence caused by winding the long object around the drum.
That is, in the process in which the long object is wound around the drum, when the part of the long object that is about to be wound around the drum comes into contact with the part that is already wound around the drum, the part that is being wound up It is unlikely that a state of being accurately wound directly on the upper side of the drum will be generated, and the winding is shifted to one of the both sides in the axial direction of the drum. In other words, the portion of the long object that has already been wound on the drum acts to shift the portion that is to be newly wound to one side in the axial direction. It is wound up in a suitable position. And since such an effect | action arises continuously, a long thing will be aligned and wound up, moving a winding position in order along the axial direction of a drum.

  However, in reality, a force (for example, a frictional force) that hinders the movement of the long object in the axial direction works, and the smooth movement of the long object in the axial direction is hindered. It tends to occur. Therefore, in the long object winding device of the present invention, the long object is not directly brought into contact with the guide body, but the long object is held by the holding body, and the holding body is supported by the guide body. . For this reason, it becomes possible to reduce significantly the frictional force which arises by the movement to the axial direction of a long thing, and can move a long thing smoothly to an axial direction. Therefore, the long object is wound up while sequentially moving the winding position along the axial direction of the drum.

However, when the long object reaches the end in the axial direction of the drum by being wound while moving the winding position sequentially in the axial direction of the drum, the long object is concentrated on the end. Makes it easier to wind up. Therefore, in the long object winding device of the present invention, the movement path formed by the guide body is held in a state where the long object is being wound from the both ends in the axial direction toward the center. The body is inclined downward , which is the direction in which the body abuts the guide body. For this reason, the force with which the holding body abuts on the guide body acts as a force for moving the holding body from the end in the axial direction to the center side. As a result, when the long object reaches the end in the axial direction of the drum by being wound while sequentially moving the winding position in the axial direction of the drum, this time, it moves in the reverse direction of the axial direction. It is wound up.

  In other words, the long object winding device of the present invention focuses on the original property that when a long object is wound around the drum, it is wound while sequentially moving the winding position along the axial direction of the drum. However, by removing the factor that hinders the property, the effect of winding up the long object evenly in the axial direction of the drum is achieved. Specifically, as described above, the frictional force with respect to the movement of the long object in the axial direction is reduced, and when the long object reaches the end of the drum in the axial direction, the movement in the reverse direction is urged. I have to.

Therefore, according to the long object winding device of the present invention, it is possible to effectively suppress the turbulence of the long object.
By the way, in order to reduce the frictional force generated by the movement of the long object in the axial direction, the holding body and the guide body are formed of a material (for example, plastic or metal) that is less likely to generate the frictional force than the long object. Conceivable. Further, as a technique for reducing the frictional force other than the material, for example, it is conceivable to provide rolling elements such as ball bearings on the holding body or the guide body.

  However, in order to effectively reduce the frictional force with a simple configuration, it is preferable to use a holding body having the following configuration, for example. In other words, the holding body has a circumferential surface formed on the outer surface, and can be moved while rolling along the guide body in contact with the guide body on the circumferential surface in a state where the winding operation of the long object is performed. It is configured. A long object winding device provided with such a holding body can be configured extremely easily compared to a configuration using a ball bearing or the like, and the frictional force generated between the holding body and the guide body can be reduced. It can be effectively reduced.

  On the other hand, the holding body can be configured to slidably hold the long object in a state where the insertion part through which the long object is inserted is formed and the insertion part is inserted. In this case, for example, the insertion portion can be formed by a spiral member, but if the insertion portion is formed by a through hole, the insertion portion can be realized with a simple configuration and a long object can be securely formed. Can be held in.

  Moreover, since it is preferable to hold | maintain a holding body in the state which does not obstruct the movement of a long thing, it is preferable that the insertion part is formed circularly seeing from the insertion direction of a long thing. According to such a structure, it can be made hard to produce that a long thing will be caught by the insertion part.

  Furthermore, in order to make it difficult to obstruct the movement of the long object in the longitudinal direction (winding direction), the inner surface of the insertion part is formed to have a curved cross section parallel to the insertion direction of the long object. preferable. According to such a configuration, the contact area between the long object and the holding body can be minimized. In particular, since the shape is curved, the contact area can be kept small even if the insertion direction (angle) of the long object with respect to the insertion portion changes somewhat. As a result, the frictional force generated at the contact portion between the long object and the holding body due to the movement of the long object in the longitudinal direction can be reduced.

  By the way, as the movement path formed by the guide body, for example, it is conceivable to have a shape curved in an arc shape or a shape bent in a V shape, but the central portion in the axial direction is parallel to the rotation axis of the drum. It is preferable that According to such a configuration, the holding body can be smoothly moved in the axial direction of the drum. That is, for example, when the position for promoting the movement of the holding body is determined at one place (V-shaped bent portion) as in a V-shape, when the holding body moves to that position (folded portion), it moves from there. The phenomenon of disappearing tends to occur. On the other hand, by preventing the central portion of the movement path from being inclined, it is possible to prevent the holding body from moving.

  In this case, the inclination of both end portions in the movement path may be a curved inclination (for example, an arc shape) or a linear inclination, but is preferably a linear inclination. If it is linear, the burden (force that inhibits movement) when the holding body moves against the inclination can be made constant, and an excessive burden can be prevented.

  Further, if the guide body is configured to support the holding body in a state where play is provided at the position of the holding body on a plane perpendicular to the axial direction, the long object is flexibly held in the winding operation of the long object. be able to.

  On the other hand, the guide body may include a grip portion that grips the drum support body with elastic force, and may be configured to be fixed to the drum support body by gripping the drum support body with the grip portion. According to such a configuration, the guide body can be easily attached to the drum support in the manufacturing process of the long article winding device.

Moreover, it is set as the structure which winds a elongate thing from the downward direction of a drum, and the movement path | route formed with a guide body inclines below toward the center side from the both ends in an axial direction. Thus, in the structure which winds a long thing from the downward direction of a drum, it becomes possible to make the height difference of a long thing at the time of winding a long thing small, and can wind up smoothly. That is, in the configuration in which a long object is wound from above the drum, the long object must be wound at a high position, and the winding position (height) changes according to the amount of the long object wound. Because of this, the holding position by the holding body is not stable. On the other hand, in the configuration in which the long object is wound from the lower side of the drum, the long object can be wound from a low position, and the winding position (height) corresponding to the winding amount of the long object is also set. Since it is difficult to change (long objects hang down regardless of the amount of winding), the holding position by the holding body is also stable. For this reason, a long thing can be wound up stably.

Embodiments to which the present invention is applied will be described below with reference to the drawings.
FIG. 1 is a perspective view illustrating an appearance of a hose reel according to an embodiment. 2 is an explanatory view showing the structure of the hose reel, where (a) is a rear view, (b) is a bottom view, (c) is a left side view, and (d) is an A-A view of (c). It is sectional drawing. 3 is an explanatory view of a holding body 60 and a guide body 70 to be described later, (a) is a perspective view seen from the back side, (b) is a top view, and (c) is B- in FIG. B sectional drawing, (d) is sectional drawing seen from the side.

  As shown in these drawings, the hose reel of the present embodiment includes a drum 10 for winding a water hose, and a drum support 20 that supports the drum 10 so as to be rotatable around a horizontal rotation axis. And.

  The drum support 20 is stretched between a support body 30 integrally formed with a pair of legs 31 and 31 by bending a metal pipe, and the legs 31 and 31 of the support body 30. A pair of drum support plates 41 and 42 and a portable hand-held portion 43 provided on the upper portion of the support body 30 are configured.

  The drum 10 has a cylindrical body 13 fixed between the disk-shaped end plates 11 and 12, and has a structure in which a hose is wound around the outer periphery of the body 13. The drum 10 is rotatably supported by the drum support plates 41 and 42 in the drum support 20 and is rotated by a rotation operation of the handle 44 provided on one (left side) drum support plate 41. It is configured. The other (right side) drum support plate 42 is provided with a connection plug 51 to which a water faucet hose as a water source is connected. The connection plug 51 has a hose wound around the drum 10. Is connected to one end of the pipe member 52 (see FIG. 2). Thereby, the tap water from the faucet is supplied to the hose wound around the drum 10 via the connection plug 51 and the pipe member 52. In particular, in the hose reel of the present embodiment, the pipe member 52 is arranged in such a direction that the hose is wound from below rather than from above the drum 10 by rotating the handle 44.

  On the other hand, the hose reel of the present embodiment includes a holding body 60 that slidably holds a portion of the hose that is not wound around the drum 10, and the holding body 60 in the direction of the axis of rotation of the drum 10 (hereinafter simply referred to as “axis”). And a guide body 70 that is slidably supported on a moving path along the direction.

The guide body 70 includes two metal wire rods 71 and 72 and resin (plastic) holding members 73 and 73 for holding them in parallel at both ends thereof.
The wire rods 71 and 72 regulate the position of the holding body 60 in the vertical direction and the front-rear direction (positions other than the axial direction), thereby supporting the holding body and forming a movement path thereof. Here, the movement path x (see FIG. 3C) formed by the wire rods 71 and 72 is linearly inclined downward from both ends in the axial direction toward the center. Moreover, the vertical width between the wire rods 71 and 72 is set to be slightly larger than the diameter of a portion (circumferential surface described later) in contact with the wire rods 71 and 72 in the holding body 60 (play is provided), In a state where the hose winding operation is performed, the holding body 60 comes into contact with the lower wire 72 by gravity (gravity applied to the holding body 60 and the hose held by the holding body 60). That is, the movement path x is inclined in the direction (downward) in which the holding body 60 comes into contact with the hose winding operation. On the other hand, the central portion of the movement path x in the axial direction is parallel (horizontal) to the rotation axis of the drum 10. The movable range in the axial direction of the holding body 60 is limited by the holding members 73 and 73.

  Each holding member 73 is formed with a gripping portion 74 that grips one leg 31 of the drum support 20 by an elastic force. The guide body 70 has a gripping portion 74 of each holding member 73 that holds the leg 31. In the gripped state, the drum support 20 is fixed. That is, the guide body 70 is configured to be detachable from the drum support body 20 without using bolts or tools.

  The holding body 60 is an annular member (roller) made of resin (plastic), has a circular through hole 61 through which the hose is inserted, and holds the hose in a state of being inserted through the through hole 61. In addition, the holding body 60 has a circumferential surface (curved surface formed by rotation about the central axis of the through hole 61. In other words, the central axis of the through hole 61 is a portion of the outer surface that abuts against the wire rods 71 and 72. The cross section perpendicular to the surface is circular. For this reason, the holding body 60 is movable while rolling along the wire rods 71 and 72 of the guide body 70 in a state where the hose winding operation is performed. In addition, the inner surface of the through hole 61 has a curved cross section (FIG. 3D) parallel to the hose insertion direction (in other words, the central axis direction of the through hole 61) bulges in the central axis direction of the through hole 61. It is formed in a circular arc shape, and it is difficult to inhibit movement of the hose in the longitudinal direction (movement in the winding direction) by reducing the frictional force generated between the hose.

  In the hose reel having the above-described configuration, the hand is soiled by rotating the handle 44 with the right hand and rotating the drum 10 in the direction of arrow C with the hose held (inserted) by the holding body 60. The hose can be wound up around the drum 10 without any trouble. At this time, it is possible to prevent the drum support 20 from moving by stepping on the leg portion 31 on the back side with the foot.

  Specifically, in the process of winding the hose around the drum 10, the part of the hose that is about to be wound around the drum 10 comes into contact with the part that is already wound around the drum 10, so It is wound up by shifting to either one. At this time, in the hose reel of the present embodiment, the hose is held by the holding body 60, and the holding body 60 is supported by the guide body 70. Therefore, the hose to be wound around the drum 10 is the holding body. 60 and move smoothly in the axial direction. In particular, since the pipe member 52 is disposed at a position biased to one side (toward the right side) in the axial direction of the drum 10, it is possible to effectively promote movement in the axial direction at the start of winding of the hose.

  Although it is possible to adopt a configuration in which the holding body 60 slides automatically (by the power of the rotation operation) in conjunction with the rotation operation of the handle 44, this makes the structure complicated and expensive. This is not preferable because it is easy to break down. In particular, in a hose reel, mud, grass, and the like are easily wound up in a state where the hose is attached to the hose. On the other hand, the hose reel according to the present embodiment has a simple structure in which the holding body 60 is supported by the guide body 70, so that not only can the cost be reduced, but also the malfunction can be prevented.

  Furthermore, in the hose reel of this embodiment, the movement path formed by the guide body 70 is inclined downward from both end portions in the axial direction toward the center side. For this reason, the force with which the holding body 60 abuts on the guide body 70 acts as a force for moving the holding body 60 from the end in the axial direction to the center side. As a result, when the hose reaches the end in the axial direction by being wound while sequentially moving the winding position in the axial direction, this time, the hose is wound while being sequentially moved in the opposite direction of the axial direction. It will be. Therefore, according to the hose reel of the present embodiment, it is possible to effectively suppress the occurrence of winding disturbance caused by winding the hose around the drum 10.

  Further, since the hose reel of the present embodiment uses the annular holding body 60, the hose reel can be configured extremely easily as compared with a configuration using a ball bearing or the like, and the holding body 60 and the guide body 70 are also provided. The frictional force generated between the wire rods 71 and 72 can be effectively reduced.

  On the other hand, the holding body 60 is an annular member, can be realized with a simple configuration, and can reliably hold the hose. Here, since the through hole 61 of the holding body is formed in a circular shape, it is possible to make it difficult for the hose to be caught in the through hole 61. Further, since the inner surface of the through hole 61 has a curved cross section parallel to the insertion direction of the hose, the contact area between the hose and the holding body 60 can be minimized. In particular, because of the curved shape, the contact area can be kept small even if the insertion direction (angle) of the hose with respect to the through hole 61 changes somewhat. As a result, the frictional force generated at the contact portion between the hose and the holding body 60 due to the movement of the hose in the longitudinal direction (winding direction) can be reduced.

  On the other hand, in the hose reel of the present embodiment, the moving path of the holding body 60 is such that the central portion in the axial direction is parallel to the rotation axis of the drum, so that the holding body 60 can be moved smoothly in the axial direction. it can. Further, since the inclination of the movement path is linear, the burden (force that inhibits movement) when the holding body 60 moves (climbs) against the inclination can be made constant, and an excessive burden is imposed. It can be avoided. Moreover, since the guide body 70 supports the holding body 60 in a state where play is provided at the position of the holding body 60, the hose can be flexibly held in the hose winding operation.

  In the hose reel of this embodiment, since the guide body 70 is fixed by gripping the drum support body 20, the mounting operation of the guide body 70 to the drum support body 20 is performed in the hose reel manufacturing process. It can be done easily.

  Furthermore, in the hose reel of this embodiment, since the hose is wound from below the drum 10, it is possible to reduce the height difference of the hose when winding the hose, and the winding is performed smoothly. Can do.

As mentioned above, although one Embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form.
For example, in the hose reel of the above-described embodiment, both ends of the moving path of the holding body 60 are linearly inclined, but the present invention is not limited to this, and may be a curved shape (for example, an arc shape). Good.

  Moreover, in the hose reel of the said embodiment, although the structure provided with the annular | circular shaped holding body 60 holding a hose with the through-hole 61 was illustrated, it is not limited to this, For example, it hold | maintains with a helical member You may form a body.

  Furthermore, in the hose reel of the above-described embodiment, a configuration is adopted in which the holding body 60 having a circumferential surface formed on the outer surface is guided by the wire rods 71 and 72 so as to be slidable, but is not limited thereto. . For example, in the case of a hose reel configured to house the drum 10 in a plastic box-shaped housing, an opening (groove) for taking out a hose is provided on the front surface of the housing, so that the guide body 70 of the above embodiment is provided. A corresponding portion may be formed, and the holding body 60 may be supported by this groove. In order to further reduce the frictional force, for example, a rolling element such as a ball bearing can be provided on the holding body 60 or the guide body 70.

  On the other hand, in the said embodiment, although the hose for water flow was illustrated as a long thing, it is not limited to this, For example, it is the same also about the winding device which winds up a gas hose, an electric cord, a wire, a rope, etc. The present invention can be applied to.

It is a perspective view which shows the external appearance of the hose reel of embodiment. It is explanatory drawing which shows the structure of a hose reel. It is explanatory drawing of a holding body and a guide body.
