Description

The present invention relates to an endless winch that can move a rope wound around a winding drum and wound around a winding drum in an endless manner by using forward and reverse rotation of the winding drum, and a rope connected to a net or a sheet. The present invention relates to a net or sheet moving system using an endless winch that suspends / opens / closes the net or sheet by moving in an endless manner.

Technology background

Generally, an endless winch is composed of a winch body provided with a drive shaft and a drive source such as a motor for rotating the drive shaft, and a rope is wound around the outer periphery of the drive shaft of the winch body. A winding drum in which a substantially V-shaped groove is formed is attached, and in the vicinity of the winding drum, a pair of guide rollers rotatably supported by a support shaft provided in the winch body is provided. The groove of the winding drum is provided with a moving guide body composed of a roller chain that has both ends positioned on the guide roller side and moves a desired distance by the rotation of the winding drum.

The moving guide body has a configuration in which one end side is connected to an elastic body such as a spring and the other end side is connected to a fixed shaft (Japanese Utility Model Publication No. 62-133594), and both end sides are connected to an elastic body such as a spring. There is a configuration (Japanese Patent Laid-Open No. 2000-351580), and the rope is moved along the groove of the winding drum while moving the moving guide body by a desired distance along the rotation direction of the winding drum using the elongation of the elastic body. And press. At this time, the rope taken into the winch body via the guide roller moves to the winding drum, and is then pushed in at one end of the moving guide body and wound along the groove of the winding drum. The other end of the moving guide body is released from pressing toward the groove side by movement, and the rope is smoothly taken out and moved again from the winch body through the guide roller.

Therefore, the configuration in which the elastic body is connected only to one end side of the moving guide body is suitable for limiting the rotation direction of the winding drum, and the configuration in which both end sides are connected to the elastic body has a single rotation direction of the winding drum. It is not limited to the direction, and it is possible to freely cope with forward / reverse rotation.

Next, as a system using the above endless winch, for example, there is a system used for moving a ball for ball prevention of a golf ball in an outdoor golf driving range facility. The facility includes a plurality of pillars erected along an outer periphery of a space portion where a golf ball is struck, a guide rope which is erected along the vertical direction of the pillars and movably inserted through a net, and the guide It is composed of a drive rope that is installed in parallel with the rope and moved in a loop in the vertical direction of the column by an endless winch. The drive rope is driven up and down the column by driving the winch during maintenance and on windy days. Move in the direction and avoid the influence of wind by lowering and storing the net along the guide rope. In use, the winch is driven again to move the drive rope in the opposite direction, and the lowered net is raised along the guide rope and suspended in the space.

As another system using an endless winch, there is a system used to partition a space portion of an indoor ball game training facility with a net. A drive rope installed in a loop to move on the ceiling side of the space with a winch, a suspension rope connected at one end to the drive rope at a fixed interval via the pulley, and the suspension rope It is composed of nets that are connected by being inserted along the vertical direction, and the drive rope is driven by the winch according to the purpose of use, and the net is suspended in the space by moving the suspension rope downward. The net is stored in the upper part of the space by moving the drive rope in the reverse direction with the winch and moving the suspension rope upward.

Problems to be solved by the invention

However, since the moving guide body provided on the endless winch moves while pressing the rope against the groove side of the winding drum, the movement distance of the moving guide body becomes large, and the end on the intake side into the rope groove becomes larger. As a result, the pressing force to the groove side of the winding drum is reduced, the idling or the like is likely to occur, and the appropriate rope pressing movement cannot be performed.

In addition, since the winding drum is used by changing the rotation direction frequently, the movement distance of the moving guide body is greatly moved in each rotation direction, and the elastic body is easily extended by the movement, so that it can be used continuously. Not suitable.

Further, when the elastic body is extended as described above, frequent maintenance such as adjustment and replacement of the elastic force of the elastic body is required.

In particular, in the case of a system in which nets and sheets are connected, the load applied to the rope is different between the side where the rope is inserted into the winch body and the side where the rope is taken out. It is not possible to properly press and wind toward the groove side, and it is impossible to reliably eliminate the bending or the like generated on the rope side with a small load.

In addition, the net or sheet increases in proportion to the size of the space, and the load applied to the rope increases, so there is a large difference in load between the rope take-in side and the take-out side, and the elastic body of the moving guide body is loaded. The replacement work that needs to be changed in accordance with this is complicated.

Therefore, the present invention appropriately moves the rope along the winding drum and smoothly moves in accordance with the load applied to the rope, and the endless winch, which has a simple configuration and excellent safety, and endless It is an object to provide a net or sheet moving system using a winch of the type.

Means for solving the problem

According to the present invention, there is provided an endless winch solving means for solving the above-mentioned problem, as described in claim 1, a winch main body provided with a drive shaft that is rotationally driven by a drive source, and a rope attached to the drive shaft. A guide drum that is rotatably supported in the vicinity of the winding drum, and a rope is taken into and out of the winch body; In an endless winch comprising a moving guide body positioned along the groove so that both ends are positioned on the guide roller side and move along with the rotation of the winding drum, a rope is attached to the moving guide body. A stopper mechanism is provided for restricting a moving distance that moves in accordance with the rotation of the winding drum while being pressed toward the groove side.

Next, the means for solving a net or seat moving system using an endless winch for solving the above-described problems of the present invention is attached to a drive shaft provided in the winch body. A rope taken into the winch body from one side through a guide roller rotatably supported in the vicinity of the winding drum in a groove formed along the outer peripheral edge of the winding drum. After winding while pressing with a moving guide body provided along the groove, it moves away from the groove on the other side of the winding drum, and is taken out from the winch body again through the guide roller and attached to the rope. In a net or seat moving system using an endless winch that moves the net or seat, depending on the load of the net or seat attached to the rope Characterized in that it restricts the movement distance of the moving guide body to move-loop with the rotation of the winding drum in a state of pressing the groove side at a desired distance.

Effects and effects of the invention

Next, the effects of the endless winch and the net or sheet moving system using the endless winch of the present invention will be described.

First, the rope is taken into the winch body through the guide roller, and further, the rope is wound from one side of the winding drum along the groove formed on the outer peripheral edge along with the rotation of the winding drum. The drum is separated from the groove from the other side of the drum and is again taken out from the winch body via the guide roller.

At this time, since both end sides are located on the guide roller side and the moving guide body is provided along the groove of the winding drum, the one end portion of the moving guide body is aligned with the rotation direction of the winding drum. Pulled along the groove and strongly pressed by the groove, the other end portion moves away from the groove side by movement.

In addition, since the movement guide body is provided with a stopper mechanism, the movement distance of the movement guide body is regulated at a desired position, so that one end portion on the intake side of the movement guide body has a rope at the same position. Pressing toward the groove side, the other end portion on the take-out side of the moving guide body is separated from the same distance groove to release the pressure toward the groove side, and moves while always pressing the rope with a constant force along the groove. be able to.

Accordingly, the rope is surely continuously taken into the groove while being pressed at the end portion of the moving guide body on one side of the winding drum, and separated from the groove at the end portion of the moving guide body on the other side of the winding drum. The pressing is released at the part and it is smoothly taken out from the groove.

In addition, since the rope is properly wound and moved as described above, the rope can be taken into the winch body and the rope can be taken out from the winch body smoothly.

Further, since the movement of the movement guide body is restricted, a strong load is not applied to the elastic body, the elastic body does not easily extend, and frequent maintenance is not required.

Next, when the drive shaft is driven in the opposite direction, the winding drum is rotated in the reverse direction, and the direction of taking in and taking out the rope from the winch body is changed, the movement of the moving guide body is reversed in the reverse direction. By moving in a restricted state along the rope, the rope take-in side to the winding drum can be moved while pressing the groove side at the end portion of the move guide, and the rope take-out side is the move guide body When the end portion is separated, the pressure is released, and the rope moves smoothly in the reverse direction as described above.

As described above, the endless winch of the present invention has a simple configuration and can move smoothly while pressing the rope into the groove formed on the outer periphery of the winding drum regardless of the moving direction of the rope. it can.

Next, the net or sheet moving stem using the endless winch is wound around the groove of the winding drum, and the net or sheet is connected to the rope that moves into and out of the winch body via the guide roller. By moving the rope, the net or sheet is suspended / stored.

At this time, because the load of the net or sheet is different between the rope take-in side to the winch body and the take-out side, the rope bends etc. on the side with less load, but the rope take-in side to the winch body is The end portion of the moving guide body is continuously taken in while pressing the rope into the groove of the winding drum, and the moving guide body moves in the pressed state in the pressed state by moving a desired distance along the rotation direction of the winding drum. Since the other end portion of the moving guide body is separated from the groove of the winding drum, the rope is released from the pressing state on the side of the rope so that the rope can be continuously taken out. You can move while solving.

Even if the load on the rope is different between the take-in side and the take-out side of the winch body, the movement distance of the moving guide body is restricted, so that one end portion of the moving guide body is fixed to the winding drum. The end part is pressed against the groove side at that position without moving beyond the position, and the rope is taken in, and the position where the other end part moves away from the groove is fixed without moving beyond the certain position, The rope can be removed and moved by releasing the pressure on the groove side.

Even if the direction of rotation of the winding drum is changed, the moving distance of the moving guide body does not move beyond a certain position in the same manner as described above, and the other end portion is pressed toward the groove side at that position, and the rope The one end portion can also be released and moved by releasing the pressure on the groove side at a fixed position separated from the groove, and can always move at a constant pressure regardless of the rotating direction of the winding drum.

Moreover, the moving guide body is restricted in the moving distance along the rotation of the winding drum, can always be pressed, and does not require frequent maintenance.

As described above, the net or sheet moving system using the endless winch according to the present invention can move reliably with the winch even when the load depending on the number and size of the nets or sheets is different.

In addition, the structure of the winch body is simple and does not require frequent maintenance unlike the conventional winch.

FIG. 6 is a schematic explanatory plan view showing a state driven in the (clockwise) direction, FIG. 6 is a schematic explanatory plan view showing a stopper mechanism, and FIG. 7 is a schematic explanatory plan view showing regulation of the distance L of the stopper mechanism in the positive direction. 8, FIG. 9, FIG. 10 and FIG. 11 are schematic explanatory plan views showing other embodiments of the endless winch of the present invention, and FIG. 12 shows a net or net using the endless winch of the present invention. A flow chart showing a sheet transfer system in FIG. 13 is a schematic diagram showing a net or sheet movement system using a winch endless manner.

An endless winch 1 according to the present invention includes a winch body 2 having a substantially rectangular shape and rotatably supporting a drive shaft, a motor connected to the drive shaft 3 of the winch body 2, and a motor for driving the drive shaft 3 to rotate. It is comprised from drive parts (not shown), such as a manual handle.

The winch body 2 rotates around the drive shaft 3 as a core, and has a disk-shaped winding drum 4 in which a substantially V-shaped groove is formed along the outer peripheral edge, and in the vicinity of the winding drum 4. A pair of guide rollers 6 (6A, 6B) rotatably supported in a parallel state, and both end portions (5A, 5B) are positioned on the guide roller 6 side, and are attached along the groove of the winding drum 4. The movable guide body 5 is composed of a roller chain.

The number and position of the guide rollers 6 are not limited to those described above, and the three guide rollers 6 can be attached in a triangular shape, and the four guide rollers 6 are attached in parallel. In addition, when the take-in direction and the take-out direction of the rope 7 are different, the rope 7 can be attached in the vicinity of the winding drum 4 according to the direction.

It is also possible to form a round or a spiral along the outer periphery of the winding drum 4.

The rope 7 used in the present invention is a generic term for a wire rope, a strong resin rope, and the like.

Since the moving guide body 5 is connected to the elastic body 9 such as a spring at both end portions (5A, 5B), the elastic body 9 is used along the rotation direction of the winding drum 4 to utilize the elasticity. It moves and presses against the groove side.

The connection of the elastic body 9 is not limited to the direct connection, and is connected to the elastic body 9 attached to the outside of the winch body 2 via, for example, a wire rope connected to the end portions 5A and 5B of the moving guide body 5. In addition, the end portions 5A and 5B of the moving guide body 5 are connected to the guide rollers 6A and 6B, respectively, and the elastic body 9 is connected to the guide rollers 6A and 6B. Can be configured to move with the rotation of the winding drum 4.

In addition, a stopper mechanism 10 for restricting the movement of the movement guide body 5 at a desired distance is provided in the approximate middle of the movement guide body 5.

The stopper mechanism 10 inserts a fixed shaft 12 attached in the vicinity of the outer periphery of the winding drum 4 of the winch body 2 into a long hole 11 formed in one roller 5H of a roller chain forming the moving guide body 5. Thus, the moving guide body 5 moves in the direction of the long hole 11 along the groove on the outer periphery of the winding drum 4 by a desired distance along the long hole 11. The movement distance L is determined by the magnitude of the load, and the distance in the length direction of the long hole 11 is adjusted.

The stopper mechanism 10 according to the present invention is not limited to the above-described configuration. For example, a long hole is formed in the vicinity of the winding drum 4 of the winch main body 2 and the long guide hole 10 is formed at the substantially central portion of the moving guide body 5. It is also possible to adjust the moving distance of the moving guide body 5 by attaching a shaft that is inserted into the hole, and a long plate with a long hole is attached and fixed to the approximate center of the moving guide body 5. It is possible to pass through the shaft 12, and it is also possible to restrict movement by attaching stop plates in the vicinity of both end portions of the movement guide body 5.

The endless winch 1 of the present invention is configured as described above. Next, a net or seat moving system using the endless winch 1 will be described.

First, the net or sheet moving system is configured such that a net 14 movably inserted at the upper end side is connected to a guide rope 13 spanned along a space portion, and a tip end side of the net 14 is connected along the guide rope 13. A rope 7 spanned in a loop via a pulley 15 and an endless winch 1 for moving the rope 7 in a loop.

The end of the rope 7 is taken into the winch body 2 via the guide roller 6A, and the winding drum 4 is rotated, and the moving guide body 5 that moves along the groove is moved into the groove from one end portion 5A. After being taken in the pressed state and wound along the groove, it moves along the rotation direction of the winding drum 4, and the other end portion 5B is separated from the groove and the other end portion of the moving guide body 5 is moved. It is taken out from 5B, taken out from the winch main body 2 through the guide roller 6B, and connected to the rear end of the rope 7 moved through the pulley 15, so that it is suspended in a loop shape. At this time, since the load due to the net 14 is different between the take-in side and the take-out side of the rope 7 to the winch body 2, one rope 7 is pulled with a strong force, and the other is weak with a weak pulling force and is likely to be loosened or bent. It becomes a state.

Next, the drive shaft 3 of the winch body 2 is rotationally driven to rotate the winding drum 4 in the forward direction (counterclockwise direction), thereby moving the rope 7 wound along the groove in the forward direction. At this time, since the movement distance of the moving guide body 5 is regulated by the stopper mechanism 10, the movement guide body 5 moves by a certain distance and reliably winds and moves while pressing the rope 7 along the groove of the winding drum 4. Can do. Therefore, even if the pulling force of the rope 7 to the winch body 2 on the take-in side is weak and bending occurs, the end portion of the moving guide body 5 is surely located at the same position at the portion of the winding drum 4 into the groove. Incorporating the rope 7 while pressing it against the groove side and moving along the groove sequentially, it is possible to eliminate the bending and move smoothly.

In addition, since the end portion of the moving guide body 5 is positioned away from the groove on the take-out side of the rope 7 from the groove of the winding drum 4, the rope 7 that has been pushed and moved easily moves out of the groove, The rope 7 pulled by a strong force can be smoothly taken out.

Further, since the movement of the moving guide body 5 is restricted, the rope 7 can be moved without pressing the groove side more than necessary, the wear of the rope 7 is small, and frequent maintenance is not required.

Further, the pulling force of the rope 7 differs depending on the size of the net 14 connected to the rope 7, but by adjusting the stopper mechanism 10, the moving distance L of the moving guide body 5 can be adjusted and the appropriate pressing of the rope 7 can be performed. Make it possible.

Next, the drive shaft is driven to rotate in the reverse direction to rotate the winding drum 4 in the reverse direction (clockwise), thereby moving the rope 7 wound along the groove in the reverse direction. Even if the take-in side and the take-out side of the winch body 2 of 7 are changed, the moving guide body 5 moves in the opposite way, and the other end separated from the groove is taken in while the end portion is pushed toward the groove side. The rope 7 is easily taken out and moved from the end portion.

Thus, the net or seat moving system using the endless winch of the present invention can move the rope 7 appropriately and smoothly in response to the load applied by the net 14.

Moreover, since the wear of the rope 7 at the time of movement is small and it can move, eliminating the bending etc. which generate | occur | produce in the rope 7, frequent maintenance is not required.

In the above embodiment, the stopper mechanism 10 is attached to the approximate center of the moving guide body 5, but the attachment position is not limited to this, and the stopper mechanism 10 can be attached to one end side. It is also possible to attach a plurality to the moving guide body 5 and further control the moving distance.

In the above embodiment, one moving guide body 5 is provided along the outer periphery of the winding drum 4. However, in the present invention, the configuration of the moving guide body 5 is not limited to this. It is divided into two parts, each end of the central part is fixed to the winch main body 2, and an elastic body 9 is connected to each end on the guide roller 6 side, so that it can be used as a moving guide body 5 with restricted movement. In this case, the fixed portion is the stopper mechanism 10. Further, by attaching the elastic body 9 to the guide roller 6 and connecting to both ends of the moving guide body 5, the configuration can be further simplified.

In the above embodiment, one winding drum 4 is attached to the winch body 2, but the number of winding drums 4 is not limited to this in the present invention, and a plurality of winding drums 4 are attached. It is also possible to attach a moving guide body 5 provided with a stopper mechanism 10 along the groove of each winding drum 4 and to move a plurality of ropes 7. In this case, the winding drum 4 can be attached to a plurality of driving shafts 3, and a plurality of driving shafts 3 are provided on the winch body 2, and the winding drums are attached to the respective driving shafts 3. 4 can also be attached.

In the above embodiment, the stopper mechanism 10 of the moving guide body 5 is fixed. However, in the present invention, the stopper mechanism 10 is not limited to this, and the fixed shaft 12 is configured to be detachable and used after being released. It is also possible to do.
