Description

The present invention, for example, moves up and down a ball-proof net provided along the outer periphery of an outdoor space such as a golf driving range, a ball-proof net suspended in an indoor practice facility, or a tent installed in the space / The present invention relates to an endless winch used for translation.

Technology background

Conventionally, a ball-proof net suspended along the outer periphery of an outdoor space such as a golf driving range is used for ball-proofing a hit golf ball. Therefore, it is necessary to move to the lower side in the case of a strong wind such as a typhoon to prevent the influence of the wind. Therefore, the ball for netting is moved up and down by wind strength and is suspended and stored.

The apparatus for moving the ball-proof net in the outdoor space part includes a driving rope that is extended endlessly along the vertical direction of each column that is erected along the outer periphery of the space part, and the driving rope. An endless winch attached to a support column for driving the vehicle, a guide rope extending in parallel with the drive rope and extending in the vertical direction, and the guide rope inserted through a ring body attached in the vertical direction And it is comprised from the ball | bowl prevention net which connected the upper end side to the drive rope.

By driving the endless winch and moving the driving rope along the vertical direction of the column, the ball-proof net moves up and down along the guide rope, and the ball-proof net is suspended and moved and stored. To do.

Further, the ball-proof net suspended from the indoor space portion moves and stores the ball-proof net according to the purpose of use of the indoor space portion.

The apparatus for moving the ball-proof net in the indoor space section is connected to the ceiling side of the indoor space section in an endless manner via a pulley, and is driven by an endless winch and fixed to the driving rope. And a plurality of suspension ropes suspended in the vertical direction of the space portion and a ball-proof net provided with a ring body through which the suspension ropes are inserted in the vertical direction.

The endless winch is driven to move the driving rope, and each suspension rope is moved up and down to suspend and store a ball-proof net whose upper end side is fixed to the ceiling side in the space.

Similarly, in the case of a tent, the driving rope is moved by an endless winch so that a plurality of tent sheets are moved in parallel to suspend the tent.

As described in JP-A-2000-351580, the configuration of an endless winch used in each of the above devices is attached to the drive shaft and a winch body provided with a drive shaft that is driven to rotate by being connected to a drive source. A rotating winding drum, a groove formed in a substantially V shape along the outer peripheral edge of the winding drum, a roller body provided along the groove and preventing the rope from detaching from the groove, and the roller A spring connected to both ends of the body and a guide roller for guiding and moving the rope to the groove side.

Another configuration of the endless winch includes a guide guide for guiding and moving the rope toward the winding drum and a plurality of guide rollers, as described in JP-A-2007-63013.

Problems to be solved by the invention

However, since the endless winch has springs connected to both end sides of the roller body, the roller body moves along the rotation direction of the winding drum, and the rope intake side to the winding drum is strong. When the rope is pressed to the groove side and the groove side on the rope take-out side does not have sufficient pressing force, and the tension on the rope on the take-out side is weak, the rope loosens or bends and the rope moves smoothly. There was a disadvantage that it was not possible.

Further, when the springs are connected to both ends of the roller body, the movement of the roller body is large due to the extension of the spring, which is likely to cause a failure and requires frequent maintenance.

Further, since the guide roller for guiding and moving the rope to the groove side and the guide guide and the roller body are not directly connected, the rope can be smoothly moved into and out of the groove due to the difference in tension on the rope. There was a drawback of not.

Further, when both end sides of the roller body are fixed, there is a drawback that the pressure on the groove side is strong on the intake side and the rope take-out side, and the wear of the rope is large.

Therefore, the present invention solves the above-mentioned problems, an endless winch that can smoothly move the rope along the rotation direction of the winding drum, has few failures, and can easily cope with a difference in tension applied to the rope. It is an issue to provide.

Means for solving the problem

Further, in order to solve the above-mentioned problems, the present invention provides a drive shaft that is rotationally driven by a drive source, a winch body provided with the drive shaft, and a groove that is attached to the drive shaft and formed along the outer peripheral edge. An endless winch comprising a winding drum that winds a rope around and a roller body that is formed of a plurality of rollers for preventing separation from the groove of the rope wound along the groove. The end rollers on both ends of each end are connected to a connecting plate that rotatably supports a moving roller on one end side, and the outer peripheral edge of the end roller is formed horizontally, A substantially U-shaped groove is formed at the periphery, and the connecting plate is rotatably supported on the winch body to swing the moving roller, and the rope is taken into the groove side, and the rope is taken out from the groove and moved. Sometimes the low Characterized in that to assist the movement of the.

According to a second aspect of the present invention, a swinging plate is pivotally supported by the connecting plate so as to be rotatable at two bottom fulcrum positions .

Effects and effects of the invention

The effects of the endless winch of the present invention will be described.

First, the rope to be taken into the winch body is moved to the groove side of the winding drum by the rotation of the moving roller supported by the connecting plate connected to one end roller of the roller body provided along the groove of the winding drum. It takes in and moves, presses the rope toward the groove with the end roller, and moves while winding the rope along the groove by the rotation of the winding drum.

At this time, the one end roller and the moving roller are connected by a connecting plate, and the connecting plate is pivotally supported by the winch body, so that the connecting plate moves the moving roller away from the groove side, Or, while swinging in the direction approaching the groove side, the end roller of the roller body is strongly pressed and moved toward the groove, or the end roller is weakly pressed and moved toward the groove.

That is, when the tension on the rope on the intake side of the winch body is strong, the connecting plate swings greatly and the moving roller is greatly rotated away from the groove, and the end roller is strongly pressed to the groove side. Moving. Thus, after the rope is taken into the groove side by the rotation of the moving roller, the rope is taken in and moved along the groove while strongly pressing the rope against the groove side with the end roller. When the tension on the rope is weak, the connecting plate swings small and the moving roller is rotated slightly in a direction away from the groove, and the end roller is weakly pressed and moved toward the groove. Thus, after the rope is taken into the groove side by the rotation of the moving rope, the rope is taken in and moved along the groove while weakly pressing the rope against the groove side with the end roller.

Therefore, the rope can be moved with an appropriate force according to the tension of the rope while assisting the take-in movement to the groove side of the rope and the pressing movement to the groove side by driving the winding drum.

The rope moves while being wound along the groove in the direction of rotation of the winding drum and pressed against the groove by the roller body.

Thereafter, the rope is taken out from the groove while being pressed toward the groove by the other end roller of the roller body, and taken out from the winch body through the other moving roller.

At this time, the moving roller and the other end roller of the roller body are rotatably connected by a connecting plate pivotally supported on the winch body, so that the connecting plate swings according to the tension applied to the rope. The moving roller moves in a direction away from the groove, and the end roller presses and moves toward the groove side, and the end roller presses toward the groove side according to the tension applied to the rope, and is taken out from the groove. The rope can be taken out from the winch main body through the moving roller, and the rope can be smoothly taken out and moved by assisting the movement of the rope by driving the winding drum.

Thus, in the endless winch of the present invention, the end roller of the roller body and the moving roller are connected via the connecting plate, and the connecting plate is pivotally supported by the winch body. Due to the movement of the roller for movement accompanying the swinging of the roller at both ends and the rolling plate, it can move smoothly along the groove according to the tension of the rope, there are few troubles such as failure, and frequent maintenance is not required.

Further, the amount of pressure applied to the groove side of the rollers at both ends of the roller body can be adjusted smoothly according to the strength of the rope tension, so that the smooth rope can be moved.

In addition, a connecting plate that is pivotally supported on the winch body at the triangular apex position from both ends of the roller body and that has one end connected to the roller on both ends of the roller body is located at the bottom two fulcrum positions (the bottom of the triangle). The swinging plate pivotally supported at the two fulcrum points) and the moving roller pivotally supported on the other end of the connecting plate, depending on the strength of the tension on the rope. The connecting plate is swung while the swinging plate is swung by the shaft support portion, the moving roller is separated from the groove side, and the end roller is pressed to the groove side.

As a result, when the tension of the rope is strong, the swinging plate and the connecting plate are swung together, and the moving roller is separated far from the groove side and the end roller is strongly pressed to the groove side. Thereby, after the rope is taken into the groove side by the rotation of the moving roller, the rope moves along the groove while strongly pressing the rope against the groove side with the end roller. In addition, since the swinging plate and the connecting plate swing in conjunction with each other, even if there is a change in the tension applied to the rope, the amount of swinging of the swinging plate and the connecting plate according to the strength can be reduced. By changing, it can respond | correspond freely, and takes in the rope by the drive of a winding drum, and assists the movement of taking out and taking out appropriately.

Further, if the tension is weak, the swinging plate and the connecting plate swing slightly in conjunction with each other, moving the moving roller smaller than the groove side and pressing the end roller weakly toward the groove side. Thus, after the rope is taken into the groove side by the rotation of the moving rope, the rope moves along the groove while weakly pressing the rope toward the groove side with the end roller. In addition, since the swinging plate and the connecting plate are interlocked, the amount of swinging can be changed according to the change in the weakness of the tension applied to the rope. Appropriate assistance for moving and taking out the rope by driving.

On the rope take-out side from the groove, the moving roller is moved away from the groove while adjusting the swinging amount of the swinging plate and the connecting plate interlocked according to the tension applied to the rope. The end roller is pressed to the groove side. As a result, the rope is taken out from the groove and moved while being properly pressed to the groove side by the end roller, and the rope is taken out from the winch body by the moving rope.

Accordingly, the rope can be smoothly moved along the groove in accordance with the driving of the winding drum.

As described above, the endless winch of the present invention is configured so that the movement of taking in and taking out the rope by driving the winding drum can be performed according to the strength of the tension applied to the rope by the interlocking of the connecting plate or the connecting plate and the swinging plate. Therefore, the rope can move without causing slack, bending and twisting of the rope.

Hereinafter, an embodiment of an endless winch of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic plan view showing a first embodiment of an endless winch according to the present invention, and FIGS. 2 and 3 show an intake movement of an end roller of the roller body and a rope of a moving roller in FIG. FIG. 4 is a schematic plan view showing a second embodiment of the endless winch of the present invention.

(First embodiment)
An endless winch 1 according to the present invention includes a drive unit (not shown) such as a motor, and a winch body 3 provided on a drive shaft 2 that is rotationally driven by the drive source. A substantially circular disc-shaped winding drum 5 having a substantially V-shaped groove 4 formed along the outer peripheral edge thereof is attached, and a roller body formed of a plurality of rollers along the groove 4 of the winding drum 5 6 is provided.

The end rollers 6A and 6B on both end sides of the roller body 6 are connected to one end side by a connecting plate 8 pivotally supported on a support shaft 7 so as to be rotatable at a substantially central portion of the winch body 3, respectively. A moving roller 9 (9A, 9B) is rotatably supported on the other end side of the connecting plate 8.

The end rollers 6A and 6B and the moving rollers 9 (9A and 9B) are rotatably supported between the two connecting plates 8, and are substantially disposed on the outer peripheral edge of the moving rollers 9 (9A and 9B). A U-shaped groove 9C is formed, and the outer peripheral edges of the end rollers 6A and 6B are formed horizontally.

With the above-described configuration, the end rollers 6A and 6B and the moving rollers 9A and 9B are pressed and moved toward the groove 4 by the swing of the connecting plate 8 that is pivotally supported, and the moving roller 9A. , 9B rotate in a direction away from the winding drum 5.

The length of the connecting plate 8 and the size of the diameter of the moving roller 9 (9A, 9B) are not particularly limited, and the moving roller 9 (9A, 9B) is provided at both ends of the roller body 6. And the end rollers 6 </ b> A and 6 </ b> B are connected by the connecting plate 8, and the rope 10 may be appropriately pressed to the groove 4 side by using the swing of the connecting plate 8.

The endless winch 1 of the present invention is configured as described above, and the case where the rope 10 connected to the net or the seat is moved next will be described.

When the rope 10 connected to a net or a sheet (not shown) is moved by the endless winch 1, first, the tip of the rope 10 is moved to the winch body 3 along the groove 9C of one moving roller 9. It takes in and moves to the groove 4 side of the winding drum 6.

The rope 10 moved to the groove 4 side is moved along the rotation direction of the winding drum 5 while being pressed against the groove 4 side by the horizontal side surface of the pressing roller 6, and the rope 10 is wound along the groove 4. To do.

After that, the rope 10 is released from the groove 4 at the other end roller 6B portion, separated from the groove 4, and taken out from the winch body 3 along the groove 9C of the moving roller 9.

The one moving roller 9 (9A, 9B) and the one end roller 6A, 6B are connected by a connecting plate 8, and the connecting plate 8 is pivotally supported on the winch body 3, so that The moving roller 9A is separated from the groove 4 of the winding drum 5 by changing the amount of swing around the support shaft 7 of the connecting plate 8 according to the strength of the tension applied to the rope 10 on the intake side. The end roller 6 </ b> A moves so as to change the amount of pressing toward the groove 4. Similarly, the other moving roller 9B changes and rotates while adjusting the amount of separation from the groove 4 of the winding drum 5, and the end roller 6B changes so as to adjust the amount of pressing toward the groove 4 side. Move.

In addition, the swinging amount of the connecting plate 8 around the support shaft 7 depends on the tension applied to the rope 10, that is, the swinging amount is large when the tension is strong, and the swinging amount is small when the tension is weak.

Therefore, when the tension is strong, the moving roller 9 rotates in a direction far away from the groove 4 and the end roller 6 (6A, 6B) strongly presses and moves toward the groove 4 side, and the rope 10 is moved to the moving roller 9. Then, the end roller 6 (6A, 6B) takes in and moves along the groove 4 while pressing strongly against the groove 4 side, or the end roller 6 (6A, 6B) moves to the groove 4 side. The rope 10 is taken out from the groove 4 while being strongly pressed to the side, and the rope 10 is taken out from the winch body 3 by the moving roller 9 and moved.

When the tension is weak, the moving roller 9 rotates in a direction away from the groove and the end roller 6 (6A, 6B) is weakly pressed and moved toward the groove 4, and the rope 10 is moved by the moving roller 9. While moving to the groove 4 side, the end roller 6 (6A, 6B) is weakly pressed toward the groove 4 side and moved along the groove 4 or moved to the groove 4 side by the end roller 6 (6A, 6B). The rope 10 is taken out from the groove 4 while being weakly pressed, and the rope 10 is taken out from the winch body 3 by the moving roller 9 and moved.

Even if the tension applied to the rope 10 changes, the swinging amount of the connecting plate 8 fluctuates in accordance with the change in the tension. Therefore, the rope 10 is always taken into the groove 4 and moved in a constant state. It can be taken out and moved.

In this way, it is possible to assist the take-in movement and the take-out movement of the rope 10 by driving the winding drum 5 according to the strength of the tension associated with the rope 10.

For this reason, it is possible to smoothly move the rope while eliminating the slack, bending and twisting of the rope caused by the strength of the tension with the connecting plate 8, the moving roller 9, and the end rollers 6A and 6B.

Moreover, since both ends of the roller body 6 are connected to the moving roller 9, the structure is simple, troubles such as failure are less than those of conventional winches, and frequent maintenance is not required.

(Second embodiment)
In the endless winch 1 of the present invention, both end rollers 6A and 6B of the pressing roller 6 of the first embodiment are arranged so that one end of the connecting plate 8 is positioned at two fulcrum positions of the triangular base (two fulcrum positions serving as the base of the triangle). The end portion is pivotally supported, the pivot plate 20 is pivotally supported at a substantially central portion of the connecting plate 8, and the winch body 3 is supported at the apex position of the swing plate 20 (a position that becomes the apex of the triangle). By pivotally supporting the support shaft 21, the swing plate 20 swings according to the movement of the roller body 6.

A moving roller 9 is rotatably supported on the other end of the connecting plate 8, and the connecting plate 8 is swung according to the strength of the tension of the rope 10, so that the moving roller 9 is separated from the groove 4. The end rollers 6A and 6B are rotated to the groove 4 side.

With the above configuration, the rocking plate 20 and the coupling plate 8 can be combined with the rocking movement. When the tension applied to the rope 10 is strong, the connecting plate 8 and the rocking plate 20 are separated from the groove 4 in a large direction. The end roller 6 (6A, 6B) is pivoted and moved strongly toward the groove 4, and the moving roller 9 is pivoted in a direction away from the groove 4. Moving.

As a result, the rope 10 is taken in and moved to the groove 4 side by the rotation of the moving roller 9A, and the end roller 6A is strongly pressed to the groove 4 side by the end roller 6A to take in and move along the groove 4, or the end roller 6B. Then, the rope 10 is removed from the groove 4 and moved while the rope 10 is strongly pressed toward the groove 4, and the rope 10 is removed from the winch body 3 by the rotation of the moving roller 9B.

When the tension applied to the rope 10 is weak, the connecting plate 8 and the swing plate 20 are small in the direction away from the groove 4 and swing around the support shaft 21 and the support shaft 21 to weaken the end roller 6A. 4 is slightly rotated and moved slightly in the direction away from the groove 4.

As a result, the rope 10 is taken in and moved toward the groove 4 by the rotation of the moving roller 9A, and the rope 10 is weakly pressed toward the groove 4 by the end roller 6A. While the rope 10 is weakly pressed by 6B, the rope 10 is taken out and moved from the groove 4, and the rope 10 is taken out from the winch body 3 by the rotation of the moving roller 9B.

Further, even if the tension applied to the rope 10 is changed, the tension can be freely changed by adjusting the amount of swing by the interlocking of the swing plate 20 and the connecting plate 8.

In this way, the take-in movement of the rope 10 into the groove 4 and the removal movement of the rope 10 from the groove 4 by driving the winding drum 5 can be assisted by the rocking movement of the rocking plate 20 and the connecting plate 8. it can.

For this reason, it is possible to deal with more delicate tension of the rope 10, and the rope 10 can be smoothly taken in and taken out from the groove 4 side.

Thus, since the rope 10 can be smoothly moved by the winding drum 5 according to the tension of the rope 10, the rope 10 can be moved while eliminating the slack, bending or twisting of the rope 10.
