JP5733643B2 - Endless winch and rope moving method using the endless winch - Google Patents

Description

The present invention mainly relates to an endless winch used for moving a rope connected to a net suspended in a space portion inside and outside an indoor space, and a rope moving method using the endless winch.

Conventionally, a net used for partitioning and ballproofing in an indoor space part is opened and closed by moving the corresponding partitioning net and ballproofing net in accordance with the purpose of use of the indoor space part. Freely close or open.

As an example of an apparatus for opening and closing the net, a plurality of pulleys attached to the ceiling side of the space, a winch attached to one side surface, a driving rope suspended between the winch and the pulley, Fix multiple suspension ropes connected to the drive rope and a fixed rope suspended at the top end along the suspension direction on the ceiling side, and attach the suspension rope along the vertical direction of the net It is composed of a net that is inserted through the ring that is fixed at the lower end, and the drive rope is moved endlessly by driving the winch, and each suspension rope is moved up and down to suspend the net in the space. Or store.

Further, the ball-proof net in the outdoor space is easily affected by the wind, and it is necessary to descend the net when the wind is strong.

The above-mentioned device for moving up and down the net of the outdoor space section includes a winch attached to the lower end side of a plurality of pillars erected along the outer periphery of the space part, a pulley attached to the upper end side of the pillar, a winch and a pulley. A drive rope suspended in an endless manner, a guide rope suspended in parallel to the drive rope, and a ring attached in the suspension direction are inserted into the guide rope, and the tip side is the drive rope The drive rope is moved endlessly by driving the winch, and the net is moved up and down along the guide rope.

The winch used for each of the indoor and outdoor devices is a winch body provided with a drive shaft that is rotationally driven by a drive source, and a substantially V-shaped groove is formed along the outer periphery of the circle attached to the drive shaft. A wound moving drum, a pressing movable body formed in a desired range of the groove of the winding drum and formed of a plurality of rollers for pressing the rope toward the groove, springs connected to both ends of the pressing movable body, etc. And a guide roller for guiding and moving the rope to the winding drum, and taking out and moving the rope from the winding drum.

Other winches include a configuration in which an elastic body is connected to only one end portion of the press moving body, and a winch that does not use an elastic body at both end portions of the press moving body.

In the present invention, a winch that moves the rope in an endless manner is defined as an endless winch.

However, in the conventional endless winch described above, when the rope is taken into the groove side, since the pressing moving body is urged by the elastic body at both ends or one end side, the rope is pushed toward the groove at one end. However, urging with only the elastic body has a drawback in that the elastic body has a different extension corresponding to the strength of the tension applied to the rope, and the rope cannot be properly pressed at all times.

In addition, since the pressing position of the rope taken into the groove side due to the strength of the tension is different, the pressing force to the rope is also different, and there is a drawback that causes the rope to wear.

In addition, since the elastic body has one end attached to the winch body as described above, the elastic force of the elastic body with respect to the pressing moving body is always constant, and the rope is attached when the tension applied to the rope is weak. There was a drawback that it could not be pressed properly to the groove side.

Further, the structure in which the swing plate is connected to both ends of the pressing moving body is a roller supported by adjusting the angle at which the swing plate rotates with respect to the fixed shaft according to the tension applied to the rope. Although the rope is pressed to the groove side, similarly, when the tension related to the rope is weak, there is a drawback that the pressure to the groove side cannot be pressed in an appropriate state.

Further, on the rope take-out side from the groove, the other end roller is separated from the groove to move along the rotation direction of the pressing movable body winding drum 5, and thus the proper pressing to the rope is not possible. there were.

Therefore, the present invention solves the above-mentioned problems, and always moves smoothly while pressing the rope toward the groove side of the winding drum optimally regardless of the strength of the tension applied to the rope, and an excessive load is not applied to the rope. An endless winch capable of moving a rope and a method of moving a rope using the endless winch are provided.

An endless winch that solves the above-described problem is, as described in claim 1, a winch body provided with a drive shaft that is rotationally driven by a drive source, and a rope attached to the drive shaft along the outer periphery. In the endless winch comprising a winding drum in which a winding groove is formed and a pressing moving body provided along a rope take-out portion from the rope intake portion to the groove, the press movement One end side of a swing plate pivotally supported by the winch body is pivotally supported by end rollers at both ends of the body, and the other end side of the swing plate is interposed via an elastic body. A connecting rotation plate that connects both ends of the pressing moving body is pivotally supported, and a roller that presses the rope toward the groove side is rotatable by swinging along the winch body on the swing plate. Features pivoting To.

Further, the rope moving method using the endless winch for solving the above-mentioned problem is as described in claim 2, wherein the rope connected to the net is taken in by the guide roller provided in the winch body, and the drive shaft is rotated. Taking in from one side while pressing with a pressing moving body into a groove formed on the outer peripheral edge of the winding drum that rotates by driving, and winding along the groove, guide rollers from the other side of the groove of the winding drum In the method of moving a rope using an endless winch that is taken out and moved through the guide roller, the guide roller is swung with a desired width regardless of the tension applied to the rope, and both ends of the pressing moving body are interlocked with the guide roller. It is supported by a part roller rotatably, in conjunction with rocking plate rocking movement within the hole in the winch body that swings elongation of the elastic body, pivoting on one of the swing plate Freely support The roller is pressed and moved to the groove side, the rope is inserted into the groove, and the other rocking plate is swung through the connecting rotating body connecting both ends of the pressing moving body to rotate the roller supported rotatably. The rope is pushed and moved to take out the rope from the groove and move.

Effects and effects of the invention

The operation and effect of the endless winch of the present invention and the rope moving method using the endless winch will be described.

First, an endless winch according to claim 1 is configured such that a rope is connected to a winding drum via a guide roller provided on a winch body in a state where a driving shaft is rotated by a driving source to rotate the winding drum. After taking in from one side and winding and moving along the groove of the winding drum, the other side of the winding drum is taken out from the groove and taken out from the winch body via a guide roller.

At this time, the rollers on both ends of the pressing moving body are pivotally supported on the winch body so that they can swing freely, and on one end of the roller is connected to the elastic body on the other end. In addition, regardless of the tension of the rope, the rocking plate can be moved along the winch body while pressing the roller toward the groove and moving the rope into the groove.

Further, in order to eliminate the tension of the rope by the extension of the elastic body connected to the rocking plate, the pressing moving body moves less along the groove, and the rope moving around the groove is appropriately placed on the groove side. Can be pressed and moved.

In addition, since the swinging plate is pivotally supported by a connecting rotary plate that connects both ends of the pressing moving body via an elastic body, the swinging plate is also provided at the portion taken out from the groove of the rope. While swinging along the winch body, the roller can be pressed toward the groove and the rope can be taken out from the groove and moved.

For this reason, the rotation of the winding drum can be transmitted to the rope without waste, and the rope can be smoothly moved without being slackened, bent or twisted.

Further, even if the rotation direction of the drive shaft rotates in the reverse direction to the above, the swinging movement of the swinging plate pivotally supported at both ends of the pressing moving body and the connecting rotating plate connected to the swinging plate In combination with the rotational movement, the rope can be smoothly moved in the same manner as described above.

Thus, in the endless winch of the present invention, the swinging plate is pivotally supported by the winch body so that the rope can smoothly move in the rotating direction of the winding drum, and the press moving body Can be moved with a desired width by the swinging plate and the connecting rotation plate, and the smooth rope can be taken in and out.

Also, whether the tension is strong or weak, the roller of the rocking plate is moved to the groove side by the rocking movement by the combination of the rocking plate and the connecting rotation plate, and the rope is securely pushed in by incorporating the rope Can move.

Next, according to the second aspect of the present invention, the rope moving method using the endless winch moves the rope connected to the net to the winding drum side by the guide roller provided in the winch body. Thereafter, the rope is pressed into the groove formed on the outer periphery of the winding drum that is rotated by the rotation of the drive shaft while pressing the rope using the pressing moving body, and the rope is wound along the groove.

Thereafter, the rope is moved from the other side of the groove of the winding drum via the guide roller, and is taken out from the winch body.

When the rope is moved into the groove of the winding drum, the guide roller swings and moves regardless of the tension applied to the rope, and can rotate to one end roller of the pressing moving body in conjunction with the guide roller. A rope is supported while the roller pivotally supported by the swinging plate is pivotally moved to the groove side by swinging in conjunction with the swinging plate pivotally supported by the winch body. Moving.

Further, the other swinging plate is swung via a connecting rotating plate that connects both ends of the pressing moving body, and the rope is supported while the roller pivotally supported on the swinging plate is pressed and moved toward the groove. It takes out and moves through a guide roller linked to the takeout.

For this reason, regardless of the strength of the tension applied to the rope, the rope can be appropriately pressed against the groove portion, and the rope can be moved smoothly.

As described above, the rope moving method using the endless winch according to the present invention can smoothly take in and take out the rope regardless of the strength of the rope by interlocking the guide roller and the swinging plate. it can.

In addition, since it can be smoothly taken in and taken out regardless of the strength of the tension, the rope can be moved while reliably eliminating the slack of the rope.

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 the endless winch of the present invention, and FIG. 2 is a schematic view showing the interlocking of the swing plate on the rope intake side and the guide roller of the endless winch of FIG. FIG. 3 is an explanatory plan view, FIG. 3 is a schematic explanatory plan view showing the interlocking of the swing plate on the rope take-out side of the endless winch of FIG. 1 and the guide roller, and FIGS. 4 and 5 are the endless method of the present invention. FIG. 6 and FIG. 7 are flowcharts showing a rope moving method using the endless winch of the present invention.

The endless winch 1 of the present invention includes a rectangular winch body 2, a drive shaft 3 rotatably supported by the winch body 2 and driven to rotate by a drive source, and attached to the drive shaft 3. A circular winding drum 5 in which grooves 4 are formed along the peripheral edge, and a rope 20 into the grooves 4 are provided along the grooves 4 in an arc shape from the take-in part to the take-out part, and a plurality of rollers are rotated. It is comprised from the press movement body 6 connected freely.

The roller 7 (7A, 7B) at both ends of the pressing moving body 6 has a substantially triangular shape in which an elliptical hole 9 is loosely fitted to a fixed shaft 8 of the winch body 2 and a roller 14 is rotatably supported. One end side of the swing plate 10 is pivotally supported.

Thereby, the pressing moving body 6 can move along the groove 4 within the range of the hole 9 of the swing plate 10.

An elastic body 11 is connected to the other end of the swing plate 10 so as to pull the pressing and moving body 6 from both sides.

The other end side of the elastic body 11 is connected to a connecting rotation plate 12 rotatably supported by a fixed shaft 13 of the winch body 2, and according to the movement of the pressing moving body 6 along the groove 4. It rotates around the fixed shaft 13.

A pair of guide rollers 15 (15 </ b> A, 15 </ b> B) are pivotally supported on the connecting rotation plate 12 so as to be rotatable around the fixed shaft 13 at equal intervals.

With the above configuration, when the rope 20 is taken into the groove 4 via the guide roller 15, the connecting rotary plate 12 is rotated in the rotating direction of the winding drum 5, and the swing plate 10 is rotated in the winding drum. 5, the roller 14 is moved to the groove 4 side.

On the take-out side of the rope 20, the swing plate 10 swings along the hole 9 in the rotation direction of the winding drum 5, and the connecting rotation plate 12 rotates in the rotation direction of the winding drum 5.

Thereby, the rope 20 can be taken in and moved to the groove 4 side while being appropriately pressed by the roller 14 on the take-in side, and the rope 20 can be taken out and moved from the groove 4 while being properly pressed by the roller 14 on the take-out side.

Further, the combination of the rotation of the connecting rotating plate 12 and the swinging movement of the swinging plate 10 corresponds to the strength of the tension of the rope 20, and when the tension is weak, only the rotating of the connecting rotating plate 12. When the elastic body 11 is not pulled strongly, the swing plate 10 is moved in the rotation direction of the winding drum 5, and when the tension is strong, the rotation of the connecting rotary plate 12, the extension of the elastic body 11, and the swing plate Corresponding with a combination of 10 movements in the rotational direction

That is, by eliminating the strength of the tension by the extension of the elastic body 11, it is possible to always perform the pressing movement toward the groove side of the roller 14 kept constant.

The endless winch 1 of the present invention is configured as described above, and the 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 the net in a state where the drive shaft 3 is driven and the winding drum 5 is rotationally driven is guided through the guide roller 15A rotatably supported by the connecting rotary body 12 to the groove of the winding drum 5. When moved to the side 4, the tension applied to the rope 20 is a combination of the rotation of the connecting rotating plate 12 in the rotating direction of the winding drum 5 and the swinging of the swing plate 10 in the rotating direction of the winding drum 5 ( The rope 20 is taken in while responding by the movement of the connecting rotary plate 12 in the direction of approaching the swinging plate 10.

At this time, the swing plate 10 swings and moves within the range of the hole 9, moves the shaft-supported roller 14 toward the groove 4, and properly fixes the rope 20 (the other end of the elastic body 11 is fixed to the winch body 2). Since the tension is not applied, the roller 14 is pressed against the strength of the tension (not strongly pressed by the roller 14 regardless of whether the tension of the elastic body 11 is different depending on the strength).

In this state, the rope 20 is smoothly taken in along the groove 4 and wound around the groove 4.

Next, on the take-out side of the rope 20, the connection rotation plate 12 rotates in the rotation direction of the winding drum 5 and the swing plate 10 also swings along the rotation direction of the winding drum 5 (connection rotation). The moving plate 12 moves in a direction away from the swinging plate 10), and the rope 20 is taken out via the guide roller 15.

At this time, the oscillating plate 10 oscillates within the range of the hole 9, moves the shaft-supported roller 14 toward the groove 4, and appropriately presses the rope 20 toward the groove 4 (the strength of the tension is reduced by the elastic body 11). The rope 20 is taken out and moved.

As described above, the endless winch 1 of the present invention can smoothly move in and out regardless of the tension applied to the rope 20.

In addition, since the rope 20 can move regardless of the tension applied to the rope 20, slack, bending and twisting of the rope 20 can be eliminated.

In the above-described embodiment, the guide roller 15 is rotatably supported on the connecting rotation plate 12. However, in the present invention, it is not essential that the guide roller 15 is supported on the connection rotation plate 12. It is also possible to pivot the roller 15 on the winch body 2.

In the above embodiment, the connecting rotary plate 12 is pivotally supported on the fixed shaft 13 of the winch body 2. However, when there are two or more guide rollers 15, the fixed shaft of the guide roller 15 is used. It is also possible to pivotally support the rotary shaft, and it is also possible to form a groove 18 with one side open in the connecting rotary plate 12 and to pivotally support the fixed shaft 11 in the groove 18. It is.
