Description

Detailed Description of the Invention

The present invention mainly uses an endless winch used to move a rope connected to a net or a tent seat in an indoor or outdoor facility, or to move a rope for raising and lowering a gondola, and the endless method. The present invention relates to a rope moving method using a winch.

Conventionally, an endless winch used for the movement of a ball-proof net for ball games is a rectangular winch body provided with a drive shaft connected directly to a drive source such as a motor or via an acceleration / deceleration mechanism, A circular winding drum that is fixedly attached to the drive shaft and has a loop groove formed along the outer peripheral surface thereof, and is rotatably supported in parallel with the winch body in the vicinity of the winding drum, A pair of guide rollers that move a rope connected to a net (a rope in the present invention is a general term for a wire rope, a resinous rope, etc. that are generally used) into and out of the groove; It is composed of a moving roller that moves along the rotational direction of the winding drum by moving the take-in movement from the guide roller and the take-out movement from the other guide roller, pressing the rope wound around the winding drum toward the groove side. There.

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

At this time, the tension on the rope is different between the take-out side and the take-in side due to the net load or the like, and the rope is likely to be loosened, bent or twisted.

As means for eliminating the slack or the like, means for connecting an elastic body to both ends of the moving roller is used. That is, the moving roller moves along the groove by pulling the rope toward the groove centering on the end roller by the urging force of the elastic body while being pulled in the rotating direction of the winding drum.

As another solution, a separate pressing member is attached to both ends of the moving roller, and the moving roller presses the rope along the groove while pressing the intake end of the rope into the groove. To solve it.

Problems to be solved by the invention

However, the endless winch described above pushes the rope taken into the groove side by the guide roller strongly against the groove side by the end roller or the pressing member of the moving roller and presses the rope wound by the moving roller. As a result, the rope is easily worn and requires frequent maintenance work in order to wind loosely and the like while forcibly eliminating slack.

Also, since the tension in the rope can be eliminated by pressing the rope taken into the groove, the twisting of the rope cannot be sufficiently eliminated, and the rope is wound around and moved. In addition, the rope cannot move smoothly.

Furthermore, there is a possibility that a new twist may occur in the rope portion slacked between the guide roller and the groove portion, and there is a drawback that the rope cannot be properly taken into the groove.

Further, if slack or the like occurs according to the tension applied to the rope on the take-out side from the groove, there is a defect that the taken-out rope cannot be smoothly moved.

Therefore, the present invention has an endless winch that has a small load on the rope, can easily eliminate slack, and can smoothly move the rope, and a rope moving method using the endless winch It is an issue to provide.

Means for solving the problem

As described in claim 1, an endless winch as a means for solving the above-described problems is a winch body provided with a drive shaft that is driven to rotate by a drive source, and is attached to the drive shaft. A winding drum, a pair of guide rollers rotatably supported on the winch body in the vicinity of the winding drum to move the rope into and out of a groove formed on the outer peripheral surface of the winding drum, and a rope In an endless winch composed of a moving roller body provided along a groove portion around which a rope is wound to be pressed against the groove side, the support shaft for supporting the guide roller is provided on one end side. A swinging plate, which is rotatably supported by an elastic body so as to pivotally support the pressing roller and urge the pressing roller toward the rope at the other end, is attached in a loosely fitted state. To the groove side And performing swinging movement in combination with the movement of the rolling movement and the vertical direction.

The rope moving method using an endless winch as a solution to solve the above-mentioned problem is as described in claim 2, wherein the drive shaft provided in the winch body is driven to rotate by a drive source, By rotating the winding drum attached to the drive shaft, the rope incorporated into the groove formed on the outer peripheral surface of the winding drum via one guide roller is pressed against the groove side by the moving roller. In the rope moving method using an endless winch that takes out and moves through the other guide roller, when the rope is taken into the groove by one guide roller, or when the rope is taken out from the groove by the other guide roller, if set and move in the rotational movement and the vertical direction to the groove side by biasing the rocking plate which is loosely fitted in the support shaft of the guide roller in accordance with the intensity of the Seal Script emissions according to-loop of an elastic body It swings the cause, and characterized in that the rope induced movement while pressing the pressing roller mounted to the swing plate in the groove side, slack rope, taken in response to deflection or twist, or extraction movement To do.

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, wherein the driving shaft is first rotationally driven by a driving source, and the rope connected to the net or the like is rotated by one guide roller while the winding drum attached to the driving shaft is rotated. The rope is moved by taking it in the winch body and winding it along a groove formed on the outer peripheral surface of the winding drum, and then moving it out from the other guide roller.

At this time, since the rope wound around the groove of the winding drum moves while being pressed toward the groove by the moving roller, the rotation of the winding drum can be transmitted without waste.

However, since the rope is connected to a net or the like, the tension applied to the rope is different between the take-in side and the take-out side of the rope to the winch body, and the rope is liable to be loosened on the weak side.

Therefore, the pressing roller supported rotatably on the swinging plate attached in a loosely fitted state to the supporting shaft of the guide roller is pressed and moved to the groove side by urging it with an elastic body. As a result, the guide roller is rotated and the rocking plate is pushed and moved while properly swinging with respect to the support shaft according to the strength of the tension applied to the rope, and the rope is taken in, or according to the strength of the tension applied to the rope. The swing plate is pushed and moved while swinging appropriately with respect to the support shaft, the guide roller is rotated and the rope is taken out, so that the slack of the rope is eliminated at the swing plate portion and the rope is guided and moved. be able to.

In other words, when the tension applied to the rope is strong, the rope is pulled straight from the guide roller to the groove of the winding drum, and the rocking plate moves little and the rope is properly pressed by the pressure roller into the groove. When the tension applied to the rope is weak, the swing movement of the swing plate is increased, the rope is linearly pulled, and the rope is strongly pressed by the pressing roller to be guided to the groove.

Thus, the rope taken in from the guide roller and the rope taken out from the guide roller can always be maintained in a straight line by the swinging of the swinging plate, and can move appropriately and smoothly.

Further, the rope can be smoothly wound and moved along the groove in a state in which the slack is eliminated, and can be taken out from the other guide roller.

Further, since the rope is wound around the groove with the slack eliminated, the rope is less worn without strongly pressing the rope against the groove side.

Next, in the method of moving the rope using the endless winch according to claim 2, first, the drive shaft provided in the winch body is rotationally driven by the drive source, and the winding drum attached to the drive shaft is rotated. Drive and take in the rope through one guide roller pivotally supported by the winch body into the winding drum groove, wind the rope along the groove, and then pull the rope from the other guide roller pivotally supported by the winch body Take out and move.

When the rope is taken into the groove of the winding drum from the one guide roller, the swinging plate loosely fitted to the support shaft of the one guide roller is urged by an elastic body so that the guide roller can be taken in by rotation. The rope swings the swinging plate according to the strength of the tension, and the pressing roller attached to the swinging plate is appropriately pressed and moved to the groove side to guide the rope in a straight line and loosen it. Guide it into the groove while solving.

According to the strength of the tension, when the tension is strong, the swinging movement of the rocking plate is small and the pressing roller is small. When the tension is weak, the rocking movement of the rocking plate is large. The pressing movement is also large.

Therefore, the rope taken into the groove can be smoothly wound and moved along the groove while being appropriately pressed against the groove side by the moving roller.

Similarly, on the rope take-out side, the rope wound around the groove is taken out from the roller part at the end while pressing the rope wound around the groove with the moving roller, and the support shaft of the other guide roller. By urging the swinging plate that is loosely fitted to the elastic plate with an elastic body, the pressing roller attached to the swinging plate is appropriately pressed against the groove side in conjunction with the moving roller, and the rope is passed through the guide roller. Remove and move.

Also in this case, the swinging motion is changed according to the strength of the tension applied to the removed rope (the swinging motion of the swinging plate is small when the tension is strong, and the swinging motion of the swinging plate is large when the tension is weak). Swing the moving plate.

As described above, the rope moving method using the endless winch of the present invention can eliminate the slack of the rope before introducing it into the groove and guide it to the groove. It can be eliminated when taking out, enabling smooth movement of the rope.

In addition, the guide roller is rotated by a fixed support shaft and a rope is taken in. The swing plate swings and moves relative to the support shaft, so that the pressure adjustment by the press roller is easy and the strength of the tension can be easily handled. can do.

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. 1 is a schematic plan view showing an embodiment of an endless winch according to the present invention, FIGS. 2 and 3 are schematic plan views showing movement of the rocking body of FIG. 1, and FIG. 4 is a rocking body. 5, 6, and 7 are schematic plan views showing other embodiments of the swinging body, and FIGS. 8 and 9 are ropes using the endless winch of the present invention. It is a flowchart of the movement method.

The endless winch 1 of the present invention has a drive shaft 2 connected to a drive source (electric motor, manual handle) directly or via a speed increasing / decelerating mechanism, and the drive shaft 2 is rotatably supported. A substantially rectangular winch body 3, a circular winding drum 4 attached to the drive shaft 2 and having a groove formed in a loop shape along the outer peripheral surface, and the winch body 3 in the vicinity of the winding drum 4 A pair of guide rollers 6 rotatably attached to a support shaft 5 fixed in parallel with each other, and attached along a groove of the winding drum 4 except between the pair of guide rollers 6 to connect a plurality of rollers. And the moving roller 7.

A pair of substantially triangular rocking plates 8 projecting in the vertical direction of the guide roller 6 are attached to the support shaft 5 provided with the guide roller 6 in a loosely fitted state via a long hole 9. A pressure roller 10 is rotatably supported on the winding drum 4 side (hereinafter referred to as one side) of the swing plate 8, and the pressure roller 10 is provided on the rope 20 intake side (hereinafter referred to as the other side). The elastic body 11 is pressed and moved in the groove direction.

The shape of the oscillating body 8 is not limited to the substantially triangular shape, and may be a rectangular shape or a semicircular shape as long as the shape is long. In short, the shape is not particularly limited as long as the pressure roller 10 can be rotatably supported on one side and an elastic body can be connected to the other side.

Further, the swing plate 8 is not limited to a pair formed in the upper and lower directions as in the embodiment, and can be formed by a single thick swing plate 8.

Further, the shape of the hole 9 formed in the swing plate 8 is not limited to the long hole as in the embodiment, and can be formed in a substantially circular shape. In short, the shape is not particularly limited as long as it is loosely fitted to the support shaft 5.

When the elastic body 11 is attached to the other end of the swing plate 8 at a position (A) parallel to the direction in which the rope 20 is taken in, the swing plate 8 moves in the vertical direction along the hole 9. When the swing is mainly performed in combination with the rotation around the support shaft 5 and is mounted at a position (B) crossing the direction of taking in the rope 20, the rotation around the support shaft 5 is mainly performed. In addition, swinging is performed in combination with movement in the vertical direction, and further fine swinging (in the vertical direction and rotation) is possible by attaching to both positions (A) and (B).

Both ends of the moving roller 7 are connected to an elastic body (not shown) so as to move a desired amount along the rotating direction of the winding drum 4.

The configuration of the moving roller 7 is not limited to the above-described embodiment, and may be a configuration in which both end sides are fixed to the winch body 3 or only one end portion is connected to an elastic body.

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, the rope 20 connected to various ballproof nets (not shown) is taken into the winch body 3 through one guide roller 6 rotatably supported on the winch body 3.

At this time, since the swinging plate 8 that rotatably supports the pressing roller 10 that is pressed and moved toward the groove by the elastic body 11 is loosely fitted to the support shaft 5 of the guide roller 6, In accordance with the strength of the tension, the swinging plate 8 swings by a combination of the pivoting movement toward the groove about the support shaft 5 and the vertical movement along the hole 9, and the rope 20 is moved by the pressing roller 10. The rope 20 is guided to the groove side while appropriately pressing.

That is, for example, when the tension applied to the rope 20 to be taken in is strong (the rope is linear), the swing plate 8 moves in the vertical direction along the hole 9 (movement within the range of the hole 9 relative to the support shaft 5). ) And rotational movement by urging the elastic body 11 (rotation movement of the rocking plate 8 that pivotally supports the pressing roller 10) is less (moving assistance of the rope 20) and guided to the groove side. When the tension is weak (the state in which the rope 20 is likely to be slackened), the rope 20 is bent, slackened, and twisted to the groove side through the guide roller 6, and the swing movement is greatly increased. (Move to press the rope 20 to eliminate slack etc.) and guide the rope 20 to the groove side.

In this way, the rope 20 can be taken into the groove after eliminating the slack of the rope 20 in advance using the swing of the swing plate 8, so that the pressing of the moving roller 10 in the groove portion can always be made constant. .

Thereafter, the rope 20 taken into the groove is pressed toward the groove side by the end roller 7 </ b> A and is wound along the groove while being pressed along the groove side by the moving roller 7, via the other guide roller 8. Then, it is removed from the winch body 3 and moved.

At this time, similarly to the incorporation of the rope 20, the rocking plate 8 that is loosely fitted to the support shaft 5 of the guide roller 6 is swung to the groove side according to the strength of the tension applied to the rope 20 to be taken out. The rope 20 can be appropriately taken out from the groove and moved using the swinging movement of the plate 8 along the hole 9.

Thus, the endless winch 1 of the present invention can guide the rope 20 into the groove by appropriately pressing the rope 20 according to the strength of the tension applied to the rope 20, and moves the rope 20 smoothly. be able to.

Further, even if the rope is slackened, bent or twisted according to the strength of the tension, it can be eliminated by utilizing the swing of the guide roller 6 and the swing plate 8.

Furthermore, since the strong pressing in the groove portion is not required, the rope 20 is less worn and the conventional frequent maintenance work is not required.

Further, since the guide roller 6 is in the fixed position, the adjustment of the swing movement by the tension of the swing plate 8 (the pressing roller 10 against the slack due to the tension of the rope 20 to be taken in and taken out around the support shaft 5). Adjustment of the combination of rotation and movement in the vertical direction along the hole 9 of the swinging plate 8) is easy, and the rope 20 can be guided and moved smoothly.
