[0001]
[Technology to which the invention belongs]
The present invention relates to a transfer wheel structure for use in an acceleration / deceleration transfer device for accelerating or decelerating a carrier in a cable traction suspension transportation facility such as a cableway.
[0002]
[Prior art]
A typical single-line automatic circulation type cableway 1z among the cable traction suspension transportation equipment including the cableway equipment is configured and operated as follows. That is, as shown in FIG. 12, pulleys 3z and 3z are pivotally provided at the stops 2z and 2z at both ends, respectively, and a rope 4z is wound endlessly between these pulleys 3z and 3z, and the cableway line It is stretched in 5z. Each stop 2z or 2z is provided with a rail 6z or 6z for guiding and rolling the carrier 10z, respectively. Along this rail 6z, a decelerating transfer device 7z is arranged on the arrival side of the carrying device 10z, and then a forward transfer device 8z is arranged along a carrying device path having a substantially U shape in plan view. Further, an acceleration transfer device 9z is disposed on the starting side of the transporter 10z. Both the stops 2z and 2z have the same configuration.
[0003]
In such a configuration, if either one of the pulleys 3z or 3z is a driving pulley provided with a driving device, the rope 4z is circulated by driving the driving pulley. As shown in FIG. 13, the carrying device 10z is constructed by suspending a carrying device main body 17z from a gripping device 11z via a suspension device 12z. The carrying device main body 17z includes a closed type passenger car type carrying device or an open type chair type carrying device. Is used. In FIG. 12, only one carrier 10z is shown in order to avoid the congestion shown in the figure, but actually, a plurality or a plurality of carriers 10z, 10z,... Are used, one after another at predetermined intervals. It is operated.
[0004]
In order to accelerate or decelerate the transporter or the gripping device by the acceleration transfer device or the deceleration transfer device in the stop as described above, a plurality of or a plurality of rubber tire wheels are arranged in parallel, and the friction force is generated by the rubber tire wheels. Conventionally, a device that sequentially performs accelerated transfer or decelerated transfer is generally used. FIG. 13 shows an example of such an apparatus.
[0005]
Wheels 16z and 16z are pivotally attached to the grinder 11z via shafts 15z and 15z so as to roll on the rail 6z, and a friction pushing plate 14z is fixed to the upper surface of the grinder 11z. It has. On the other hand, the acceleration transfer device 20z (9z) pivots a plurality of transfer wheels 60z, 60z... On a transfer wheel shaft 30z or 30z. A large-diameter pulley 26z and a small-diameter pulley 27z are fitted to the transfer wheel shafts 30z, 30z..., And a large-diameter pulley 26z and a small-diameter pulley 27z of the transfer wheels 60z and 60z adjacent to each other. A belt 29z is wound around each other so as to maintain a speed ratio and are connected so as to be able to transmit rotation. In such a connection configuration, when one belt 29z is driven, the transfer wheels 60z, 60z,... Are driven one after another through the belts 29z, 29z, and the rotational speed thereof is directed in the direction of the arrow 18z, which is the traveling direction of the carrier 10z. The driving speed is gradually increased. This driving force is taken from the movement of the rope through the pulley, or from a wheel driven by the rope for driving force intake, or it can be driven by the power of another electric motor. Has been done.
[0006]
On the other hand, the friction push plate 14z of the grinder 11z is brought into contact with the transfer wheels 60z, 60z... One after another and is transferred by friction while being guided to the rail 6z by the traveling wheels 16z, 16z, and thus the speed of the carrier 10z is increased. It is pushed and transferred while gradually accelerating. The effective length of the friction pushing plate 14z is determined to be at least equal to or longer than the arrangement interval or arrangement pitch of the transfer wheels 60z, 60z. This is because at least one transfer wheel 60z is always attached to the friction pushing plate 14z. They are in contact so that the pushing force is not interrupted.
[0007]
However, as shown in FIG. 13, in the case of accelerated transfer, when the state in which the friction push plate 14z is in contact with the two transfer wheels 60z and 60z is examined, from the above relationship, When the tangential speed of the peripheral edge of the transfer wheel 60z is V, the tangential speed of the peripheral edge of the next transfer wheel 60z is at least (V + dV), and there is a speed difference, so the two transfer wheels 60z and 60z have a friction push plate 14z. Is in contact, it means that a slip has occurred at any point.
[0008]
Such slip actually occurs and causes various adverse effects. First, slip causes wear to the rubber tire wheel or friction push plate of the transfer wheel to promote wear, and slip causes unpleasant squeak or other slip noise, or loss of drive power due to these causes It is to produce. Furthermore, the rapid fluctuation of forward and reverse torsional torque loaded on the transfer wheel shaft promotes fatigue of the transfer wheel shaft, and causes fatigue breakage of the transfer wheel shaft.
[0009]
On the other hand, several proposals have conventionally been made as measures for solving such a problem of slipping between the harmful transfer wheel and the friction push plate.
[0010]
That is, in Japanese Utility Model Laid-Open No. 3-130767, "Acceleration and deceleration transfer device for automatic circulation cableway", the transfer wheel is provided by being restrained by a guide that is movable by a predetermined interval in the longitudinal direction of the transporter. There has been proposed a technique in which the transfer wheel is slidably moved in accordance with the speed difference of the wheel to compensate, and the slip between the transfer wheel and the friction push plate is to be eliminated.
[0011]
In addition, in Japanese Utility Model Publication No. 3-130765 “Acceleration / Deceleration Transfer Device in Automatic Circulation Cableway”, it is effective in transmitting torque in one direction between the transfer wheel and the transfer wheel shaft, and is idle in the other direction. There has been proposed one in which a clutch means such as a one-way clutch is interposed. In addition, since this device is not effective in the opposite direction, for example, when the transporter runs away, it has been proposed to incorporate a transfer wheel for preventing the runaway for every fixed number of transfer wheels.
[0012]
Furthermore, in Japanese Utility Model Laid-Open No. 4-107161, "acceleration / deceleration transfer device for automatic circulation type cableway", a clutch clutch means and a helical spring are inserted between the transfer wheel shaft and the transfer wheel. Has been proposed.
[0013]
However, although these achieve the required purpose for the time being, there have been some merits such as the complexity of the apparatus.
[0014]
The above is a description of the case of an automatic circulation type cableway as a representative example of the rope pulling suspension transportation equipment, but in the traveling line, a rigid rail type rope pulling suspension of a type that travels by being guided by a rigid rail. In the case of transportation facilities, the mode of acceleration and deceleration at the stop is exactly the same as in the case of cableway facilities, and here there are also problems of equality.
[0015]
[Problems to be solved by the invention]
The present invention has been made for the purpose of further improving the above-described circumstances. In a frictional feed type acceleration or deceleration transfer device for an automatic circulation type cableway facility such as a cableway, a frictional feed plate in a gripper of a portable device is provided. Even when transported in contact with two transfer wheels with different peripheral speeds, mutual friction does not occur on the friction surface, and the structure of the apparatus is relatively simple and stable in operation. It was made for the purpose of providing the acceleration / deceleration transfer wheel structure of the traction pull suspension transportation equipment.
[0016]

Conductive means 25p (25).
[0022]
In FIG. 3, the transfer wheel shaft 30p (30) pivots around the intermediate portion 32p of the transfer device beam 21p (21) for supporting the transfer wheels 60p (60), 60p (60) via a bearing 22p. It is supported freely. A small-diameter pulley 27p (27) and a large-diameter pulley 26p (26) are fitted near one end 31p of the transfer wheel shaft 30p (30). A belt 29p (29) or 29p (29) is wound around the small-diameter pulley 27p (27) and the large-diameter pulley 26p (26), respectively, and the belt 29p (29) of the small-diameter pulley 27p (27).

Drive transmission is transmitted to the transfer wheel shaft 30p (30) on the downstream side of the drive through a predetermined speed increasing ratio.
[0023]
The transfer wheel shaft 30p (30) is pivotally supported by the bearing 22p in the vicinity of the intermediate portion 32p as described above, but the hollow portion 35p is formed on the coaxial core in the vicinity of the other end portion 33p extending to the left in the drawing. Perforated and formed. On the other hand, the locking connecting member 50p, which is a hollow bag-like cap or cap-like member with a hook, is pivotally supported in the vicinity of the other end 33p of the transfer wheel shaft 30p (30) via a bearing 65p on the inner surface side. Has been. In addition, a tire holding member 67p is fixed to the flange 64p of the locking connecting member 50p, and a rubber tire 61p is fitted to the outer periphery thereof.
[0024]
Here, a torsion elastic means 40p or a torsion bar 41p, which is a characteristic configuration of the present invention, is interposed between the transfer wheel shaft 30p (30) and the locking connecting member 50p. .
That is, the hollow portion 35p of the transfer wheel shaft 30p (30) is locked and connected to the torsion elastic means 40p by the locking connection portion 36p, and the torsion elastic means 40p is connected to the locking connection portion 51p on the other hand. It is the structure connected with the latching continuous member 50p inner surface. In this configuration, that is, the transfer wheel shaft 30p (30) driven by the conduction means 25p (25) is configured to drive the transfer wheel 60p (60) via the torsional elastic means 40p. The friction push plate 14 of the grinder 11 is frictionally transferred at the peripheral edge 62p of (60).
[0025]
Here, in this drawing, the case where the torsion bar 41p is used as the torsional elastic means 40p is shown schematically, but other members having the same torsional elastic function are similarly used. It is possible.
[0026]
The operation or operation of the first embodiment of the invention configured as described above is as follows.
[0027]
As shown in FIG. 2, in the accelerated transfer device 20 (9), transfer wheels 60, 60... Are pivotally mounted on the transfer device beam 21 via transfer wheel shafts 30 or 30. Each of the transfer wheel shafts 30, 30... Is fitted with a large-diameter pulley 26 and a small-diameter pulley 27, and a belt is provided between the large-diameter pulley 26 and the small-diameter pulley 27 adjacent to each other. In this way, the transfer wheels 60, 60... Are configured such that the tangential speed of the peripheral edge gradually increases in accordance with the traveling direction of the transporter 10.
[0028]
In the carrying device 10, the friction pushing plate 14 of the gripping machine 11 is brought into contact with the peripheral portions 62, 62... Of the rubber tyres 61 of the transfer wheels 60, 60. Here, since the peripheral portion 62 of the transfer wheel 60 adjacent to each other and the peripheral portion 62 of the next transfer wheel 60 have a speed difference dV with the traveling direction of the transporter 10, the transporter 10 proceeds. As a result, it is pushed and transferred while being gradually accelerated. Here, the interval between the transfer wheels 60 and 60 adjacent to each other is at least shorter than the length of the friction push plate 14 of the grinder 11, and at least one transfer is performed during the transfer operation. The wheels 60 are always in contact with the friction push plate 14 so that the transfer operation is not interrupted.
[0029]
In the accelerated transfer device 20 having such an arrangement relationship, the transfer wheel shaft 30p (30) and the transfer wheel 60p (60) are configured as shown in FIG. 3 as described above. That is, the small-diameter pulley 27p (27) fitted to the transfer wheel shaft 30p (30) rotates from the large-diameter pulley 26p (60) of another adjacent transfer wheel 60p (60) through the belt 29p (60). The transfer wheel shaft 30p (30) is pivotally supported by the bearing 22p and rotates. This rotation is transmitted to the torsion bar 41p which is the torsional elastic means 40p, and is transmitted to the transfer wheel 60p (60) via the locking connection member 50p.
[0030]
Thus, the torsion bar 41p transmits torque by being interposed between the transfer wheel shaft 30p (30) and the locking connecting member 50p. When the transfer torque is small, the torsion bar 41p does not cause torsional displacement, so the transfer wheel shaft 30p (30) and the locking communication member 50p or the transfer wheel 60p (60) rotate in the same phase, and the relative advance rotation or delayed rotation between the transfer wheel shaft 30p (30) and the bearing 65p. They are rotating in the same phase. When the transmission torque is large in either the positive or negative direction, the torsion bar 41p responds to this by causing the torsional displacement in the forward or reverse direction while causing the torsional displacement from the transfer wheel shaft 31p (30) to the locking connecting member 50p or the transfer wheel. The rotation is transmitted to 60p (60). In this case, phase advance rotation or delayed rotation occurs between the transfer wheel shaft 30p (30) and the locking connecting member 50p, and the bearing 65p rolls or slides on the transfer wheel shaft 30p (30). Is absorbed.
[0031]
A flange 64p extends outwardly from the locking connection member 50p in a bowl shape, and a tire holding member 67p is fixed to the concentric core. The grinder 11 is rubbed around the tire holding member 67p. A rubber tire 61p to be transferred is fitted.
[0032]
4, 5 and 6 illustrate the state of transfer. In the figure, three transfer wheels 60 (60A), 60 (60B), and 60 (60C) in the acceleration transfer device 20 (9) are schematically shown. The traveling direction of the machine 11 is shown. Here, the tangential speed of the peripheral edge of the transfer wheel 60 (60A) is V, the tangential speed of the peripheral edge of the transfer wheel 60 (60B) is (V + dV), and the tangential speed of the peripheral edge of the transfer wheel 60 (60C) is (V + dV + dV), and there is a speed difference dV between adjacent transfer wheels.
[0033]
In FIG. 4, the friction push plate 14 of the grinder 11 is in contact with only one transfer wheel 60 (60A) and is frictionally transferred to travel in the direction of the arrow 18. At this time, the grip pusher 11 is transferred. The speed is V. When the grinder 11 further advances in the direction of the arrow 18, as shown in FIG. 5, when the friction push plate 14 is frictionally transferred to the transfer wheel 60 (60A) and enters the area of the transfer wheel 60 (60B), the transfer wheel 60 ( 60A) is torsionally displaced in the direction of rotational advance by torque, and the transfer wheel 60 (60B) rotates in a delayed manner and is coordinated with the transfer wheel 60 (60A). When the transfer by the transfer wheel 60 (60B) gradually becomes dominant, the speed of the friction transfer plate 14 becomes (V + dV), and the torsion bar 41p of the transfer wheel 60 (60A) is twisted and displaced in the rotational advance direction by the torque. Therefore, the transfer wheel 60 (60A) advances and rotates to follow the transfer wheel 60 (60B) and perform coordinated transfer. In this way, since the coordinated transfer is performed while performing the delayed rotation and the advanced rotation, harmful slip between the transfer wheel 60 (60A) or 60 (60B) and the friction transfer plate 14 is kept to a minimum.
[0034]
In this way, the transfer speed of the grinder 11 is accelerated from V to (V + dV), and as shown in FIG. 6, it is transferred at the speed (V + dV) only by the transfer wheel 60 (60B). Be transported. Furthermore, the delivery transfer is performed smoothly to the next transfer wheel 60 (60C) as well.
[0035]
In this way, the torsion bar 41p which is the torsional elastic means 40p is interposed, and the transfer wheel 60p is advanced and delayed to compensate in accordance with the feeding state of the transfer wheel 60p (60) and the friction pushing plate 14. Therefore, slip does not occur between the transfer wheel 60p (60) and the friction push plate 14, or can be kept to a minimum.
[0036]

A belt 29 or 29 is wound around the large-diameter pulley 26 and the small-diameter pulley 27, respectively, and the belt 29 of the small-diameter pulley 27 passes through a predetermined speed increasing ratio from the transfer wheel shaft 30 on the adjacent upstream side of the drive. Driven by the transmission of the driving force, the driving force is transmitted from the large-diameter pulley 26 to the transfer wheel shaft 30 on the downstream side of the drive via the belt 29 through a predetermined speed increasing ratio.
[0040]
Next, in the vicinity of the other end portion 33 of the transfer wheel shaft 30, a ring core portion 63 on the transfer wheel 60 side is pivotally attached via bearings 65 and 65. The ring core portion 63 is a boss-like member having a hollow cylindrical shape as shown in FIG. 7, and a flange 64 to which a tire holding member 67 to be described later is fixed extends outwardly in a bowl shape on the outer peripheral side. Yes. That is, bearings 65 and 65 are fitted around the other end 33 of the transfer wheel shaft 30, and the outer peripheral sides of the bearings 65 and 65 are fitted into the hollow hole 63 a of the ring core 63. At the same time, the position is determined by using the retaining rings 66, 66, so that the ring core part 63 is pivotally supported. Rolling bearings such as balls, rollers, and needles or sliding bearings can also be used for the bearings 65 and 65. Further, a nut 38b is screwed and fastened to the threaded portion 37b of the other end portion 33 of the transfer wheel shaft 30 so that the axial position of the bearing 65 or the ring core portion 63 is determined to prevent dropping. A tire holding member 67 is fixed to the flange 64 concentrically with a bolt or the like, and a rubber tire 61 to be a friction contact surface is fitted on the outer periphery of the tire holding member 67.
[0041]

When the transfer torque is small, the torsion bar unit 42 does not cause torsional displacement, so The locking communication member 50 or the ring core portion 63 rotates in the same phase, and there is no relative advance rotation or delayed rotation between the transfer wheel shaft 30 and the bearings 65 and 65, and the rotation phase rotates in the same phase. Yes. When the transmission torque for moving the grinder is large in either the positive or negative direction, the torsion bar unit 42 is locked and connected from the transfer wheel shaft 31 while generating a torsional displacement in the forward or reverse direction in response to this. The rotation is transmitted to the member 50 or the ring core portion 63. In this case, phase advance rotation or delayed rotation occurs between the transfer wheel shaft 30 and the locking connecting member 50, and the bearings 65 and 65 roll or slide on the transfer wheel shaft 30 to absorb this. Yes.

【The invention's effect】
Conventionally, an acceleration transfer device or a deceleration transfer device used for a cable traction suspension transporting facility including a cableway facility includes a plurality of rubber tire wheels arranged in parallel, and an acceleration transfer or a deceleration transfer by frictional force has been widely used. It is used. In such a friction transfer device, two transfer wheels having a speed difference are brought into contact with the friction push plate to perform transfer, so that slip occurs at any point, and this causes friction to the rubber tire wheel or the friction push plate of the transfer wheel. In addition to causing wear and tear, generating unpleasant noise, or loss of drive power, etc., and in addition to applying a sudden torque change to the transfer wheel shaft, the transfer wheel shaft is fatigued or destroyed. Hazardous problems such as the cause of the occurrence.
[0055]
The acceleration / deceleration transfer wheel structure of the cable traction suspension transportation equipment such as a cableway of the present invention has a torsional elastic means, that is, a torsion bar or the like interposed between the transfer wheel shaft and the transfer wheel, torsionally elastically deforming the torsional elastic means. The transfer wheel is configured to be able to advance or rotate with respect to the transfer wheel shaft. Since it is possible to prevent slippage between the transfer wheel and the friction push plate of the grinder, various adverse effects such as wear, noise, and member fatigue can be eliminated. In addition, when the one-way clutch as described in the section of the prior art is used, since it is not effective in the direction opposite to the transfer, it is necessary to take measures to stop it. In the case of the structure of the present invention, Has the advantage of acting effectively in either the forward or reverse direction.
[0056]
Further, in each of the above-described embodiments, the case of the acceleration transfer device has been described. However, even in the case of the deceleration transfer device configured so that the peripheral speed of the transfer wheel gradually decreases with the traveling direction of the transporter. Of course, the same applies. And in each of the above-described embodiments of the invention, the case of the automatic circulation type cableway equipment was described as a representative example of the rope pulling suspension transporting equipment, but in the traveling line, it is guided by a rigid rail. In the case of a rigid-rail-type cable traction suspension transportation system, the acceleration and deceleration modes at the stop are exactly the same as those in the cable system, and can be similarly applied.
