Description

Detailed Description of the Invention

The present invention mainly uses an endless winch used for moving a rope connected to a net or a seat in indoor or outdoor facilities, or for moving a gondola lifting rope, and the endless winch. It relates to the method of moving the rope.

Conventionally, an endless winch used for moving a ball-proof net for ball games is a rectangular type in which a drive shaft connected directly to a drive source such as a motor or indirectly through an acceleration / deceleration mechanism is rotatably supported. A winch body having a shape, a circular winding drum that is fixedly attached to the drive shaft and has a groove formed in a loop shape along the outer peripheral surface, and a position parallel to the winch body in the vicinity of the winding drum A rope that is pivotally supported by and connected to a net (in the present invention, a rope is a generic term for a wire rope, a resin rope, etc. that are generally used) is taken into and taken out of the groove. A pair of guide rollers for assisting the movement, and a winding drum provided between the one guide roller and the other guide roller along the groove of the winding drum, while pressing the rope wound around the groove Desired in the direction of rotation Moving, and a moving roller body formed by connecting a plurality of rollers.

The endless winch rotates a drive shaft with a drive source, rotates a winding drum attached to the drive shaft, and turns a rope into a groove of the winding drum via one guide roller. The rope is wound around the groove while being taken in and pressed by the moving roller body along the groove, and the rope connected to the net is moved endlessly by taking out the rope from the other guide roller side.

At this time, the tension of the moving rope differs depending on the net load and the weight of the rope due to the weight of the rope, and the tension on the take-out side of the winding drum is different from that on the take-in side. Is likely to occur, and the rope cannot be smoothly moved to the groove side.

As means for eliminating the slack, etc., means for connecting elastic bodies by springs to both ends of the moving roller body was used. In other words, the end roller of the moving roller body is connected to one end side of the elastic body, and the other end side of the elastic body is connected to the winch body.

As a result, when the winding drum rotates, the moving roller body is pulled in the reverse direction by being biased in the direction opposite to the rotation direction by the elastic body while being pulled in the rotation direction of the winding drum. The rope can be pushed and moved along the groove by another roller while the rope is pushed into the groove side and the rope is taken in.

Further, as another means, by providing an elastic body for adjusting the pressure of the rope on both end rollers of the moving roller body, the rope is inserted into the groove while the both end ropes of the moving rope are pressed toward the groove side. It can be pressed and moved along.

Problems to be solved by the invention

However, in the conventional endless winch, the elastic body is connected to the end roller of the moving roller body and the end roller presses the rope to the groove side, so the pressing position to the groove side is constant. There is a defect that it is limited within the range and cannot be adjusted by pressing at an appropriate position according to the strength of the rope tension.

Also, since the end roller of the moving roller body mainly performs the pressing action to the groove side, it cannot be guided to the appropriate groove side according to the strength of the tension, and there is a slack of the rope etc. There is a drawback that the slackness cannot be sufficiently eliminated between the guide roller and the end roller.

In addition, since the elastic body is strongly biased, the rope is forcibly pressed at the intake end portion into the groove, and there is a drawback that the rope is heavily worn at this portion.

Also, on the side that is taken out from the groove, the end roller moves in the direction of rotation of the winding drum and the urging force by the elastic body does not work sufficiently. There was a drawback that the rope could not be taken out and moved appropriately in response to the strength of the tension.

Further, since the rope is taken into the winch body via the guide roller, there is a drawback that the rope has a distance between the guide roller and the groove of the winding drum, and the slack of the rope occurs in this portion.

Accordingly, the present invention provides an endless winch that can reduce slack and the like with little load on the rope and enables smooth rope movement, and a rope moving method using the endless winch. The issue is to provide.

Means for solving the problem

As described in claim 1, an endless winch as a solving means for solving the above-described problem is a winch body provided on a drive shaft that is rotationally driven by a drive source, and is attached to the drive shaft and is attached to an outer peripheral surface. A winding drum for winding a rope in a groove formed along the groove, and a groove formed between the take-in side and the take-out side of the rope to the winding drum, and formed by connecting a plurality of rollers In the endless type winch composed of the moving roller body, the both ends of the moving roller body are respectively wound according to the strength of the rope tension, and the rope intake side is wound with the end-side roller. Energizing in the rotating direction of the rotating drum, urging the roller on the other side in the opposite direction to the rotating direction of the winding drum, and starting from the moved position. And starting from the position moved urges La in the rotational direction of the drum for winding, adjacent a desired position so as to urge the opposite direction the roller end portion side in the rotation direction of the drum for winding An elastic body for adjustment formed by a substantially U-shaped leaf spring is connected between the rollers to be moved, and each end roller of the moving roller body is directly or indirectly fixed to the winch body, and each end portion The rope is taken in and taken out from the winch body through a roller.

According to another aspect of the present invention, there is provided a rope moving method using an endless winch in which a drive shaft provided on a winch body is driven to rotate by a drive source. , By rotating a winding drum attached to the drive shaft, a rope was introduced from one side into a groove formed on the outer peripheral surface of the winding drum, and a plurality of rollers were connected to form In the method of moving a rope using an endless winch that winds along the groove while being pressed toward the groove by a moving roller body and takes in the rope from the other side of the winding drum, the moving roller One end side of the body takes in the rope through an end roller fixed directly or indirectly to the winch body, and the rope at a desired position according to the tension of the taken-in rope. With urges along the roller end portion side in the rotational direction of the drum for winding the attached adjusting elastic member between La, after urging the other side roller in the direction opposite to the rotation direction, said other side The roller was wound along the groove starting from the position where the roller moved along the groove, and the other side of the moving roller body was attached between the rollers at a desired position according to the tension of the rope taken out from the groove. urges the end portion of the roller by adjusting the elastic member in a direction opposite to the rotation direction of the drum for winding, after urging the rollers of the other side along the rotational direction, the roller of said other side into the groove Starting from the position moved along, the rope is taken out from the winch body and moved through end rollers fixed directly or indirectly to the winch body.

Effects of the invention

The effects of the endless winch for the ball game of the present invention and the rope moving method using the endless winch will be described.

The endless winch according to claim 1 is a winch in which a drive shaft is first rotationally driven using a drive source, and a rope connected to a net or the like is rotated while a winding drum attached to the drive shaft is rotated. Take in the main body, wind the rope along the groove formed on the outer peripheral surface of the winding drum from one side of the winding drum, take out the rope from the other side of the winding drum, and from the winch body Take out and move.

The rope wound around the groove of the winding drum moves while being pressed toward the groove by the moving roller body.

At this time, since the rope is connected to a net or the like, the tension applied to the rope is different on the take-in side and the take-out side of the rope to the winch body, and the rope is loosened, bent or twisted on the weak side. Is likely to occur.

Therefore, according to the tension applied to the rope, between the desired adjacent rollers on the end roller side on both ends forming the moving roller body (the end roller side or a position separated from the end roller side) The adjustment elastic body is connected to the position of.

As a result, the rope take-in side, after the rope is directly taken into the winch body by one end roller fixed directly or indirectly to the winch body, the rope is rotated by the adjusting elastic body in the rotation direction of the winding drum. The rope is guided to the groove side by the end side roller urged by the roller, and the rope is pushed to the groove side starting from the other roller side urged in the direction opposite to the rotation direction of the winding drum. I can move.

Further, the rope take-out side presses the rope toward the groove starting from the other roller side biased in the rotation direction of the winding drum by the adjusting elastic body, and is opposite to the rotation direction of the winding drum. After the rope is guided and moved by the roller on the end side urged by, the rope is directly taken out from the winch body and guided through the end roller.

For this reason, slack or the like that occurs in the rope can be eliminated by using the elasticity of the portion that directly takes in and takes out the rope via the end roller and the roller portion that is the starting point of the pressing action on the groove side. it can.

In addition, it is possible to freely change the starting point of the pressing action on the groove ridge by simply changing the position where the adjusting elastic body is connected between the rollers, and the mounting position can be adjusted to the optimum position according to the strength of the tension. Can be changed.

In this way, the adjusting elastic body can be freely installed at the same position or different positions on the intake side and the take-out side of the winding drum groove, and should be properly installed at a position corresponding to the strength of the rope tension. Can do.

With respect to the strength of the tension, when the tension applied to the rope is strong, the adjustment elastic body is connected between the positions close to the end roller of the moving roller body, so that the rope is close to the take-in and take-out side. When the rope is pressed and the tension of the rope is weak, the adjustment elastic body is connected between the rollers separated from the end roller of the moving roller body, and the rope is pressed at a position farther from the rope take-in and take-out side. As a result, the cable can be taken into and taken out from the groove while always eliminating the slackness of the rope.

Further, the rope can be appropriately guided and wound as described above, and the rope can be smoothly moved without applying a strong load as in the conventional case.

Next, in the method of moving the rope using the endless winch according to claim 2, the drive shaft provided in the winch body is first rotationally driven by the drive source, and the winding drum attached to the drive shaft is rotated. The rope is driven to rotate, the rope is taken into the groove of the winding drum, the rope is wound along the groove, and then the rope is taken out from the groove of the winding drum and moved.

When the rope is taken into the groove of the winding drum, the end roller of the moving roller body is fixed directly or indirectly to the winch body, so the rope is directly taken into the winch body via the end roller. The adjustment elastic body connected to a desired position between adjacent rollers allows the end side roller to guide the rope to the groove side while pressing the rope toward the groove side, and starts from the other roller of the connecting portion. While the rope is pressed toward the groove, the moving roller body is moved in the rotational direction to press and move the rope.

After that, on the opposite side of the moving roller body (the rope take-out side), the rope is taken out from the groove starting from the other roller portion connected to the adjustment elastic body, and the rope is guided by the roller on the end side and pressed against the rope. However, the rope is taken out from the winch body and guided through an end roller fixed directly or indirectly to the winch body.

The connection position of the adjustment elastic body is determined according to the strength of the tension applied to the rope. That is, when the tension is strong, the elastic body is connected to the moving roller body at a position close to the end roller, and when the tension is weak, the connection position of the adjusting elastic body is separated from the end roller. Connect to a position.

For this reason, when the tension is strong, the rope can be pressed starting from a position near the rope intake side of the winding drum, and when the tension is weak, the end is separated from the rope intake side of the winding drum. It can be guided into the groove while being guided by the part side roller, and pressed into the groove while pressing the other roller as a starting point.

As described above, the rope moving method using the endless winch of the present invention freely adjusts the connecting position of the adjusting elastic body, always presses the rope to the groove side at an appropriate position, and moves in and out. It can be taken out and moved.

Further, by changing the connection position of the adjustment elastic body on the take-in side to the groove side of the rope and on the take-out side from the groove, different tensions can be dealt with freely.

In addition, the slack of the rope can be eliminated before being taken into the groove and guided to the groove, and the slack of the rope can be eliminated when the rope is taken out from the groove, enabling smooth rope movement. .

Further, since the rope can be moved easily and smoothly as described above, the wear of the rope is small and the conventional frequent maintenance work is not required.

Next, an endless winch of the present invention and a rope moving method using the endless winch will be described with reference to the drawings.

FIG. 6 is a schematic explanatory view showing the connection and movement of the adjustment elastic body according to the strength of the tension, FIGS. 6 and 7 are schematic plan views showing another embodiment of the connection of the adjustment elastic body, and FIG. FIG. 9 and FIG. 10 are schematic plan views showing other embodiments of the endless winch of the present invention, and FIGS. 11 and 12 are endless views of the present invention. It is a flowchart of the moving method of the rope using the winch of a system.

An endless winch 1 according to the present invention includes a drive shaft 2 connected to a drive source (electric motor, manual handle) directly or via an acceleration / deceleration mechanism such as a clutch or a brake, and the drive shaft 2 is rotated. A substantially rectangular winch body 3 that is freely supported, a circular winding drum 4 that is attached to the drive shaft 2 and has a groove formed in a loop shape along the outer peripheral surface, and the winding drum 4, and a moving roller body 7 formed by connecting a plurality of rollers 8.

End rollers 8A and 8Z at both ends of the moving roller body 7 are rotatably provided on shafts 9A and 9Z fixed to the winch body 3, and one end is adjacent to the adjacent end roller 8A and the next roller. 8B, and the adjustment elastic body 10 formed from a leaf spring having a substantially U-shape in cross section is attached between the adjacent end roller 8Y and the front roller 8X. ing.

That is, on the rope 20 take-in side (one side in the embodiment), one end of the adjustment elastic body 10 is connected to the end roller 8A and the other is connected to the roller 8B. The roller 8 </ b> B is urged in the direction opposite to the rotation direction by the adjustment elastic body 10.

That is, the rope 20 directly taken into the winch body 3 via the end roller 8A pivotally supported by the winch body 3 is guided while being pressed toward the groove by the end roller 8A, and along the groove. Starting from the position of the other roller 8B that has moved, the rope 20 is pushed into the groove side and incorporated. The rope 20 taken into the groove is wound around the groove while being pressed toward the groove by the moving roller body 7 moving along the groove.

On the take-out side of the rope 20 (the other side in the embodiment), the end side rollers 8Z and 8Y are urged in the direction opposite to the rotation direction of the winding drum 4, and the other roller 8X is urged in the rotation direction. Is done.

As a result, the rope 20 is pressed toward the groove starting from the position of the other roller 8X moved along the groove, and is supported by the winch body 3 by being guided by the end side rollers 8Z and 8Y from the groove. The rope 20 is taken out from the winch body 3 through the end roller 8Z.

In the above embodiment, the adjustment elastic body 10 on the intake side is attached between the end roller 8A and the adjacent roller 8B. However, the attachment position of the adjustment elastic body 10 is not limited to this, and the tension elastic body 10 is not limited to this. It is also possible to attach between the roller 8B and the roller 8C separated from the end roller 8A, or between the roller 8C and the roller 8D, and the end roller 8A on one side and the other It is also possible to attach the adjustment elastic body 10 to the same position with the end roller 8Z on the side. In short, any desired roller 8 adjacent to each of the end rollers 8A and 8Z can be freely connected.

Further, the number of the adjustment elastic bodies 10 attached to the end roller 8A, 8Z side is not limited to connecting one to the end roller 8A, 8Z side as in the embodiment, It is possible to connect the adjusting elastic body 10 only between the rollers 8 on the take-in side of the rope 20, or to connect the plurality of adjusting elastic bodies 10, respectively, so that the pressing force to the groove side of the moving roller body 7 can be further increased. It is also possible to adjust.

Further, the fixing method of the both end rollers 8A, 8Z to the winch body 3 is not limited to the method of rotatably attaching to the shaft 9 fixed to the winch body 3 as in the above-described embodiment. By indirectly fixing to the winch main body 3 with the fixed shaft 12 through the end rollers 8A and 8Z, it is possible to apply the urging force along the rotation direction by the adjusting elastic body 10 and swing the end rollers 8A and 8Z. Further, the guide 20 can be guided and moved more smoothly at the end rollers 8A and 8Z. At this time, the end roller 8A on one side is indirectly fixed to the winch body 2 with the fixed shaft 12 via the connecting plate 11, and the other end roller 8Z is directly fixed to the winch body 3 with the fixed shaft 9Z. By doing so, it is also possible to position the rope 20 having a weak tension on the end roller 8A side and smoothly move the rope 20 using the swing of the end roller 8A.

Further, the configuration of the moving roller body 7 is not limited to a configuration in which a plurality of rollers are connected as in the embodiment. For example, only a plurality of both end sides of the moving roller body 7 are provided. It is formed by a single roller 8 and is composed of a combination in which the rollers 8 on both side surfaces are connected by arc-shaped leaf springs 13, so that the movement of the moving roller body 3 along the groove is further flexible. Incorporation of the rope 20 into the winch main body 3 and pressing on the groove side can be adjusted flexibly.

That is, the elasticity of the leaf spring 13 is used while pressing the rollers 8C and 8X connected to the leaf spring 13 toward the end rollers 8A and 8Z, respectively, and the urging of each roller by the adjusting elastic body 10 is combined. Thus, the buffering force of the end side rollers 8A and 8B and the end roller 8Z can be further increased, and the rope 20 can be smoothly guided to be taken in, and the rope 20 can be smoothly taken out. it can.

The endless winch 1 of the present invention is configured as described above. Next, a case where the rope 20 connected to the net is moved using the endless winch 1 will be described.

First, when the rope 20 connected to various ballproof nets (not shown) is taken in and moved, the rope 20 is winched while the drive shaft 2 is rotated by a drive source and the winding drum 4 is rotated. Incorporated into the main body 3, moves to the groove of the winding drum 4, and moves while winding the rope 20 against the groove side by the moving roller 7.

At this time, the rope 20 taken in is guided to the groove side by the end roller 8A pivotally supported on one winch main body 3 of the moving roller body 7 and directly taken into the winch main body 3 and is also used as a winding drum. The rope 20 is taken into the groove while pressing the rope 20 toward the groove starting from the position moved along the groove of the other roller 8B connected to the adjusting elastic body 10 urged in the direction opposite to the rotational direction 4. . That is, it corresponds to the strength of the tension applied to the rope 20 between the end roller 8A and the other roller 8B.

That is, when the tension is strong, the rope 20 is not loosened, so the adjustment elastic body 10 is connected between the end roller 8A and the other roller 8B adjacent to the end roller 8A, and the end roller 8A is pressed and guided. When the tension is weak, the adjustment elastic body 10 is connected between the end roller 8A and the roller 8D at a separated position, and the slack of the rope 20 is appropriately eliminated by using the distance L on the end roller 8A side. However, the rope 20 is smoothly moved in a state in which the slackness and the like are eliminated by being guided into the groove.

Thereafter, the rope 20 taken into the groove is wound along the rotation direction of the winding drum 4 while being pressed toward the groove by the moving roller body 7.

Next, when the rope 20 is taken out and moved, the rope 20 is taken out from the groove and moved from the other side while being pushed and moved toward the groove by the moving roller 7.

That is, the rope 20 is pressed to the groove side starting from the other roller 8X moved along the groove and urged by the adjusting elastic body 10, and the rope 20 is pushed to the groove side by the end rollers 8Z and 8Y. By guiding while pressing, it can be taken out from the winch body 3 by taking out from the groove via the end roller 8Z after corresponding to the strength of the tension applied to the rope 20.

Specifically, when the tension of the rope 20 to be taken out is strong, since the rope 20 is not slack, etc., the adjustment elastic body 10 is connected between the end roller 8Z and the roller 8Y at a close position, and the roller 8Y The rope 20 is pressed toward the groove from the starting point, guided and taken out while being pressed by the end roller 8Z. When the tension is weak, the adjusting elastic body 10 is positioned between the rollers 8X and 8W at a position away from the end roller 8Z. , The roller 20X is used as a starting point, the rope 20 is pressed to the groove side, and the end roller 8Z is pressed and guided by a long distance to remove the twist of the rope 20 and move.

In particular, since the other end side rollers 8Y and 8Z are composed of two rollers, the installation area with respect to the rope 20 is expanded, and slack or the like generated in the rope 20 can be eliminated more reliably. The expansion of the installation area can be handled freely by adjusting the position where the adjustment elastic body 10 is connected.

For this reason, slack, bending and twisting of the rope 20 due to the strength of the tension applied to the rope 20 can be eliminated at the stage of guided movement to take in the groove or the stage of guided movement to take out from the groove. Can be done smoothly.

Therefore, in the movement by the winch 1 as in the prior art, the load can be distributed and the wear of the rope 20 can be clearly reduced regardless of the excessive load on only a part of the rope 20.

In addition, since the adjustment elastic body 10 can be connected to a free position, the rope 20 can be appropriately guided and pressed to the groove side, and does not require frequent maintenance work as in the prior art.

Further, by adjusting the mounting position of the adjustment elastic body 10, the pressing movement of the moving roller body 7 can be freely adjusted, and can be freely set according to the purpose of use.

In the above-described embodiment, the diameter of the roller 8 constituting the moving roller body 7 is formed to be the same, but only the both end rollers 8A and 8Z can be formed to have a larger diameter than the other rollers. Thereby, the slack etc. which generate | occur | produce in the rope 20 at the time of taking in and taking out of the rope 20 can be eliminated more easily using the difference in diameter between the end rollers 8A and 8Z and the other rollers.
