Description

[0001]
[Technology to which the invention belongs]
The present invention relates to a transfer tire used in an acceleration / deceleration transfer device that accelerates or decelerates a transporter in a cableway facility.
[0002]
[Prior art]
A typical single-line automatic circulation type cableway 40 of the cable pulling and pulling transportation system including the cableway equipment is configured and operated as follows. That is, as shown in FIG. 8, pulleys 42 and 42 are pivotally provided at the stop points 41 and 41 at both ends, respectively, and a rope 43 is wound endlessly between these pulleys 42 and 42, and the cableway track. 44 is stretched. Each stop 41 or 41 is provided with a rail 45 or 45 for guiding and rolling the carrier 100, respectively. Along this rail 45, a decelerating transfer device 70 is disposed on the arrival side of the transporter 100, and then a forward transfer device 60 is disposed along a transporter path having a substantially U shape in plan view. Further, an acceleration transfer device 50 is disposed on the departure side of the transporter 100. Both the stops 41 and 41 have the same configuration.
[0003]
In such a configuration, if either one of the pulleys 42 or 42 is a driving pulley provided with a driving device, the rope 43 is circulated by driving the driving pulley. As shown in FIG. 9, the transporter 100 is formed by suspending a transporter body (not shown) from a grinder 101 via a suspension unit 105, and this transporter body includes a closed passenger car transporter or an open transporter. A chair-type carrier is used. In FIG. 8, only one carrier 100 is shown in order to avoid the congestion shown in the figure. However, actually, a plurality or a plurality of carriers 100, 100... 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 stopping place as described above, a plurality or a plurality of rubber tire wheels are arranged in parallel, and friction force is generated by the rubber tire wheels. Conventionally, a device that sequentially performs accelerated transfer or decelerated transfer is generally used. FIG. 9 shows an example of such an apparatus.
[0005]
Wheels 102, 102 are pivotally attached to the grinder 101 via shafts 103, 103 to roll the rail 45, and a friction transfer plate 104 is fixed to the upper surface of the grinder 101. It is prepared. On the other hand, the acceleration transfer device 50 pivots a plurality of transfer tires 55, 55... On a transfer device beam 51 by transfer tire shafts 54, 54. A large-diameter pulley 52b and a small-diameter pulley 52a are pivotally attached to the transfer tire shafts 54, 54, respectively, and a belt 53 is provided between the large-diameter pulley 52b and the small-diameter pulley 52a of the transfer tires 50 and 50 adjacent to each other. Is connected so as to be able to transmit rotation while maintaining a speed ratio. When one belt 53 is driven in such a connection structure, the transfer tires 50A, 50B, 50C, 50D,... Are driven one after another through the belts 53, 53,. It is driven so that the transfer speed gradually increases in the direction of an arrow 106. This driving force is configured to be taken out from the movement of the rope 43 through the pulley 42 or from a wheel driven by the rope 43 for taking in the driving force, or driven by the power of another electric motor. It has also been done.
[0006]
On the other hand, the friction transfer plate 104 of the grinder 101 is brought into contact with the transfer tires 55A, 50B, 50C, 50D,... The speed of the transporter 100 is pushed and transferred while being gradually accelerated. The effective length of the friction transfer plate 104 is determined to be at least equal to or longer than the arrangement interval or arrangement pitch of the transfer tires 55, 55. This is because at least one transfer tire 55 is always attached to the friction transfer plate 104. They are in contact so that the transfer force is not interrupted.
[0007]
However, as shown in FIG. 9, in the case of accelerated transfer, when the friction transfer plate 104 is in contact with the two transfer tires 50B and 50C, the relationship is as follows. When the tangential speed of the peripheral edge of the transfer tire 50 is V, the tangential speed of the peripheral edge of the next transfer tire 50 is at least (V + dV), and there is a speed difference. Therefore, the friction transfer plate 104 exists between the two transfer tires 50B and 50C. Is in contact, it means that a slip has occurred at any point.
[0008]
On the other hand, several proposals have heretofore been made as measures for solving the problem of slip between the transfer tire and the friction transfer plate.
[0009]
That is, in Japanese Utility Model Laid-Open No. 3-130767, “Automatic Circulation Cable Acceleration and Deceleration Transfer Device”, the transfer tire 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 that the transfer tire slides and compensates for the tire speed difference to eliminate the slip between the transfer tire and the friction transfer plate.
[0010]
In Japanese Utility Model Laid-Open No. 3-130765 “Acceleration / Deceleration Transfer Device for Automatic Circulation Cableway”, it is effective for transmitting torque in one direction between the transfer tire and the transfer tire 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 tire that prevents the runaway for every fixed number of transfer tires.
[0011]
Furthermore, in Japanese Utility Model Laid-Open No. 4-107161, “acceleration / deceleration transfer device for automatic circulation type cableway”, an engagement clutch means and a helical spring are inserted between the transfer tire shaft and the transfer tire. Has been proposed.
[0012]
However, although these achieve the required purpose, there are merits and demerits such as a complicated apparatus.
[0013]
In addition, the above describes the case of a single-line automatic circulation type cableway as a representative example of the cable-drawing suspended transporting equipment. Even in the case of a suspended transport facility, the mode of acceleration and deceleration at the stop is exactly the same as in the case of a cableway facility, and here there is a problem of equality.
[0014]
[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 friction transfer type acceleration or deceleration transfer device of an automatic circulation type cableway facility such as a cableway, a friction transfer plate in a gripper of a portable device is provided. It was made for the purpose of providing a transfer tire for use in an acceleration / deceleration transfer device of a rope pulling / suspending transport facility that enables an operation to be accelerated or decelerated by contacting two transfer tires having different peripheral speeds. is there.
[0015]
In response to this object, the present invention provides an acceleration or deceleration transfer device for accelerating or decelerating a carrier between a slow speed and a rope speed in a cableway, wherein the acceleration or deceleration transfer device includes a plurality of transfer tires. Are arranged in parallel, and the transfer tire contacts the friction transfer plate of the carrier and is accelerated or decelerated by friction, and the entire circumference of the outer periphery of the transfer tire is perpendicular to the feed direction. The transfer tire is formed so as to be inclined with respect to a line so that the contact state between the serrated protrusion and the friction transfer plate differs between the forward direction and the reverse direction due to the inclination. The magnitude of the frictional force acting on the friction transfer plate of the transporter at the projection is made different between the frictional force acting in the forward movement direction of the transporter and the frictional force acting in the reverse direction. Two different abuts Among the feeding tires, the protrusion of one of the transfer tires is pushed up and deformed to cancel the speed difference so that the friction forces of the two transfer tires are different. The outer peripheral portion of the protrusion is inclined toward the traveling direction of the transporter at the contact portion with the transfer plate, and the protrusion of the transfer tire of the speed reduction transfer device is disposed at the outer peripheral portion of the protrusion at the contact portion with the friction transfer plate. Inclined to the opposite side.

The belt 27 and the belt 27 are wound around the small-diameter pulley 26a as a pair. Accordingly, the tangential speed V of the peripheral edge increases in the order of the transfer tires 35A, 35B, 35C, and 35D as it proceeds in the direction of the arrow 18 in proportion to the diameter ratio between the large diameter pulley 26b and the small diameter pulley 26a. come.
[0020]
FIG. 4 is a front view showing a partial cross section of a structure in which a transfer tire 35 and a pulley 26 are pivotally attached to the transfer device beam 21 via a transfer tire shaft 24. The transfer device beam 21 is formed using a square steel pipe. The transfer device beam 21 is fixed by penetrating a cylindrical bearing holding portion 22 in the horizontal direction. Further, a bearing 23 and a bearing 23 are respectively fitted to both ends of the bearing holding portion 22, and the transfer tire shaft 24 is pivotally supported by the bearings 23 and the bearings 23 at both ends. Then, a collar 29 is sandwiched between the bearing 23 and the collar 29 at the right end of the transfer tire shaft 24 in the drawing, and the flange 30 and the collar 33 are inserted from the ends and tightened to the tire shaft 24 with two nuts 34 and 34. And stick. Next, the rim 32 on which the transfer tire 35 is mounted is fixed to the outer peripheral edge of the flange 30 with bolts 31, 31,.
[0021]
Next, a pulley 26 having a small diameter pulley 26a and a large diameter pulley 26b is inserted from the shaft end with a collar 25 next to the bearing 23 to the left end side of the transfer tire shaft 24 in the figure, and then tightened with a nut 28 in the same manner. Adhere to. That is, the transfer tire 35 and the pulley 26 are pivotally attached to the transfer device beam 21 integrally with the bearing 23 and the bearing 23 via the transfer tire shaft 24. As described above, the belt 27 and the belt 27 are wound around the small-diameter pulley 26a and the large-diameter pulley 26b of the pulley 26, respectively.
[0022]
In the carrying device 10, the friction transfer plate 14 of the grinder 11 is brought into contact with the transfer tires 35, 35,... One after another, and is pushed and transferred on the rail 6 by friction. Here, since the speed difference dV is held in the traveling direction of the transporter 10 between the outer peripheral part 35b of the transfer tires 35 adjacent to each other and the outer peripheral part 35b of the next transport tire 35, the travel of the transporter 10 proceeds. As a result, the feed is transferred while being gradually accelerated.
[0023]
Further, the transfer tire 35 and the transfer tire 35 adjacent to each other are arranged at intervals shorter than at least the friction transfer plate 14 of the grinder 11, and during the transfer operation, at least one wheel is provided. It is determined that the transfer work is not intermittently caused by the transfer tire 35 being in constant contact with the friction transfer plate 14.
[0024]
Among these, the transfer tires 35, 35,... Shown in FIG. A plurality of protrusions 35 a, 35 a,. On the other hand, as shown in FIG. 3, convex projections 14a, 14a,... Are formed on the upper surface of the friction transfer plate 14 fixed to the upper surface of the grinder 11.
[0025]
Next, the state at the time of the gripping machine 11 of the carrying device 10 being transferred by the acceleration transfer device 9 using the transfer tires 35, 35,... Formed as described above will be described. As shown in FIGS. 3, 6, and 7, when the two-wheel transfer tire 35 </ b> B and the transfer tire 35 </ b> C rotating at the speed difference dV contact the friction transfer plate 14 of the grinder 11, they rotate quickly in the direction of the arrow 18. The sawtooth-shaped protrusions 35a, 35a,... Formed on the outer peripheral portion 35b of the transfer tire 35C on the side to be engaged with the protrusions 14a, 14a,... Formed on the upper surface of the friction transfer plate 14 as shown in FIG. The rope 11 is pushed and transferred in the direction of the arrow 18.
[0026]
At this time, the projections 35a, 35a,... Formed on the outer peripheral portion 35b of the transfer tire 35B on the side that rotates slowly are projections 14a, 14a,... Of the friction transfer plate 14 as shown in FIG. The frictional transfer plate 14 is slid by being deformed so as to be pushed up in the direction, thereby compensating for the speed difference dV between the tangential velocity V of the transfer tire 35B and the frictional transfer plate 14. Thus, when the two wheel transfer tire 35 and the transfer tire 35 are simultaneously contacted with the friction transfer plate 14 of the grinder 11, the transfer is performed following the tangential velocity V of the transfer tire 35 on the side that rotates faster. That is, as shown in FIG. 2, in the acceleration transfer device 9, the tangential speeds V of the transfer tires 35, 35,... Arranged side by side in the traveling direction of the transporter 10 are the transfer tires 35A, 35B, 35C with a speed difference dV. , 35D in order, and the grinder 11 of the carrier 10 is brought into contact with the rotating tires 35A, 35B, 35C, 35D that rotate in this manner, and is accelerated and transferred in the direction of the arrow 18. .
[0027]
On the other hand, in the decelerating transfer device 7 arranged in parallel along the rail 6 on the arrival side, the sawtooth projections 35a, 35a,... Formed on the outer peripheral portions 35b, 35b,. The mounting is performed so that the inclination of the angle θ is opposite to the starting side with respect to the vertical line VL. Thus, when the two transfer tires 35, 35 come into contact with the friction transfer plate 14 of the grinder 11, the transfer tire 35 on the side where the protrusions 14a, 14a, ... formed on the friction transfer plate 14 rotate slowly. Are formed in the transfer tire 35 on the side that rotates faster, and the friction transfer plate 14 is deformed in the same manner as in the case of the acceleration transfer device 9 described above. By slipping, the speed difference dV is compensated. Accordingly, in the case of the decelerating transfer device 7, the grinder 11 is transferred following the transfer tire 35 rotating at the slow tangential speed V, so that the grinder 11 of the transporter 10 is successively transferred to the transfer tire 35 as it advances. , 35,... Are decelerated and transferred.
[0028]
【The invention's effect】
Conventionally, an accelerating transfer device or a decelerating transfer device used in a rope pulling and suspending transportation facility including a cableway facility is a device in which rubber transfer tires are juxtaposed along a rail and the carrier is accelerated or decelerated by frictional force. More widely used.
[0029]
In the case of such an acceleration transfer device or a deceleration transfer device, there is always a speed difference between adjacent transfer tires, and in order to solve this, a one-way clutch or a spring is interposed between the transfer tire and the transfer tire shaft. Therefore, a structure that eliminates the speed difference between the transfer tire and the gripping device of the transporter is often used. On the other hand, the transfer tire used in the acceleration transfer device or the deceleration transfer device of the present invention is formed with a plurality of sawtooth-shaped protrusions having asymmetric left and right sides in the rotation direction on the outer peripheral portion. In addition, a protrusion having a convex shape that meshes with the protrusion formed on the transfer tire is also formed on the upper surface of the friction transfer plate of the grinder that comes into contact therewith. In this way, the frictional force acting in the tangential direction when the friction transfer plate comes into contact with the transfer tire is made to differ greatly in the direction opposite to the forward movement direction of the transporter.
[0030]
In this way, when the friction transfer plate of the grinder is in contact with two transfer tires having different speeds, the friction transfer plate is transferred at the tangential speed of the transfer tire having the larger frictional force. If the transfer tires that rotate fast in order in the direction in which the frictional force always increases in the direction of travel of the transporter due to this action are arranged, the transporter is transported on the faster side in the acceleration transfer device via the gripping device. Are sequentially transferred and accelerated. On the other hand, in the decelerating transfer device, if the transfer tires that rotate slowly in the direction in which the frictional force always increases in the traveling direction of the transporter are arranged, the transporter is sequentially transported by the transfer tire on the slow side via the grinder. Decelerated. Thereby, it is possible to omit devices and members such as a one-way clutch and a spring that are interposed between the conventional transfer tire and the transfer tire shaft, and it is possible to realize an acceleration transfer device and a deceleration transfer device that are simple in structure and inexpensive. effective.
