JP4454017B2 - Individual carrier information management device for automatic circulation type cableway - Google Patents

Description

  The present invention relates to an apparatus that can acquire and store information on a carrier of an automatic circulation type cableway individually for each carrier and can be used for maintenance and management of the carrier.

  The automatic recirculating cableway stretches and circulates the endlessly between the two stops and suspends the rope from the rope using a carrier that can hold and release the rope. It is widely used as a transport facility on slopes such as ski resorts. Generally, the gripping machine used in this automatic circulating cableway transporter has a built-in spring. The repulsive force of this spring is applied to the gripping part for gripping the rope. Many methods are used to firmly adhere to the strip. And while the cable grinder is fixed to the rope in the cableway, the repulsive force of the spring is released with a lever etc. in the cable grinder, and it is separated from the cable and sent at low speed. After turning to the opposite track, it is fixed to the rope again and departs to the opposite stop.

  As described above, in the grinder for the automatic circulation type cableway, every time it arrives at the stop and departs, it is fixed to the rope (grasp) and separated (release). By repeating the operation of the rope, the spring of the gripping machine may gradually sag or wear may occur in the grip part.

  The gripping machine is an important device that suspends the carrier on this and grips the rope and fixes the carrier to the rope, so it always manages the state of the spring or the progress of wear on the handle. It is important to. In view of such circumstances, conventionally, a method has been proposed in which individual carrier information is stored in a database for identification (see Patent Document 1).

In this patent document 1, in order to identify individual carriers, character marking means such as numeric pattern signs or bar code marks are marked at predetermined locations on the carriers, and the carriers are routed through the stop. The character detection means that can identify and recognize these characters to recognize and detect the individual carrier, and then the detection data from each detector provided at a plurality of positions through which the carrier passes, The data of the individual transporters is stored and stored in a database as a set. And by doing in this way, the situation of a failure, etc. are accumulate | stored for every individual carrier in a database, and this data can be utilized effectively for maintenance management and safety management.
Japanese Patent No. 2645882

  However, since the automatic circulation type cableway is often operated in a snowy area such as a ski resort, snow and ice are often frozen on the carrier. And in the technique of the above-mentioned patent document 1, when the snow icing on the carrying device covers the character marking means, the character detecting means cannot recognize the carrying device, or it is erroneously recognized and correctly detected. There was a problem that data could not be stored. Further, in the above technique, failures that occur in individual carriers are accumulated, and although it is possible to grasp the tendency of the individual carriers to cause an abnormality, it is difficult to detect the occurrence of failures in advance.

  The present invention has been made in consideration of such circumstances, and recognizes and detects each individual portable device accurately without being affected by the icing condition and dirt state of the portable device. By managing and monitoring and managing the status data of each vehicle, it is possible to always accurately grasp the status of the transporter, and to manage individual transporter information that makes it easy to detect abnormalities in the transporter in advance. To provide an apparatus.

In order to achieve this object, in the present invention, an RFID tag storing carrier information for identifying a carrier for each carrier is attached to a carrier of an automatic circulation type cableway, A reader / writer and an antenna having a function of reading carrier information stored in the RFID tag and sequentially writing data to the RFID tag, and for measuring a spring force of a gripping device provided in the carrier The RFID tag is housed in a case and attached to the carrier, and the antenna is installed at a position before the carrier is turned from the arrival side to the departure side and is forwarded and accelerated. The carrier information and spring force information are stored in a database, and are configured as an individual carrier information management device for an automatic circulation type cableway.

  In the above, the reader is a reader / writer having a function of sequentially writing data to the RFID tag.

  According to the apparatus of the present invention, since the carrier information is read using the RFID tag and the reader, the carrier information can be surely read even if snow or dirt adheres to the RFID tag, and accurate data is obtained. Can be accumulated.

  In addition, since these data are stored in a database, statistical analysis and data retrieval can be easily performed, and it is easy to detect abnormalities in the gripper in advance and to schedule overhauls. It can contribute to navigation.

  If a reader / writer having a function of writing data is used instead of the reader, data can be held in the database and the RFID tag, and even if one of the data is lost, it is quickly restored. Is possible.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing one stop of an automatic circulation type cableway. The rope 10 is looped endlessly between a pulley 11 pivoted at this stop and a pulley at the other stop, and circulates and moves along the cable track by driving one pulley. In the cable track, a gripping machine provided in a plurality of transporters 14 grips the strips 10 and operates the transporters 14 along with the movement of the strips 10.

  A U-shaped running rail 12 that opens in the direction of the cableway is fixed to the outside of the pulley 11 at the stop, and a large number of tires 13, 13,... Is installed. In the stop constructed as described above, the transporter 14 is operated as follows.

  First, when the carriers 14, 14,... That grip the rope 10 enter the stop from the cableway, the rollers provided in the gripper of the carrier 14 are supported by being in contact with the traveling rail 12, and the traveling is performed. The grinder or transporter 14 rolls while being guided by the rail 12. After this, the grappler unloads the line and is disconnected from the line 10. At this time, the tire 13 is in contact with the upper part of the grinder, and thereafter the grinder is pushed by the rotational driving force of the tire 13 and the transporter 14 is transferred.

  On the arrival side of the transporter 14, the tire 13 is set so that the number of rotations sequentially decreases in the direction in which the transporter 14 travels. Therefore, after the cable is released, the transporting speed of the transporter 14 is gradually reduced. . Then, when the speed of the transporter 14 reaches a low speed, it is forwarded and transferred to the departure side in a U-shape with the constant speed at the low speed, and is then gradually accelerated to the same speed as the speed of the rope 10. When it reaches, the rope 10 is seized and it departs to the cableway. In the stop, the above operation is sequentially performed every time a plurality of carriers 14, 14,.

  A gripping machine used in such an automatic circulation cableway is of a type that grips the rope 10 by utilizing the repulsive force of a spring. FIG. 2 shows an example of such a spring type grinder.

  The gripping machine 20 includes a fixed gripping member 21 and a movable gripping member 22. In the drawing of the fixed gripping member 21, an arc-shaped gripping portion 21a is formed at the left end so as to conform to the outer shape of the strip 10, and the strip 10 is attached to the gripping portion 21a. A gripping portion 22a of the movable gripping member 22 is similarly formed in an arc shape on the opposite side. The fixed gripping member 21 and the movable gripping member 22 are coupled to each other by a pin 23 above the gripping portions 21a and 22a, and the movable gripping member 22 is rotatable about the pin 23. .

  Next, a spring case 26 is attached to the main body portion 21b of the fixed handle member 21 so as to be rotatable in the directions of arrows A and B. A long torsion bar 29 is inserted in the spring case 26, one end of the torsion bar 29 is fixed to the fixed grip member 21, and the other end is fixed to the spring case 26. By configuring in this way, for example, when the spring case 26 is rotated in the direction of the arrow B relative to the fixed gripper member 21, the torsion bar 29 is twisted and bent, and the spring case 26 is moved in the direction of the arrow A. Generates a repulsive force to return.

  An arm portion 27 protrudes upward from the upper portion of the spring case 26. Near the upper end of the arm 27, one end of a lever 28 is pivotally connected via a pin 24, and the other end of the lever 28 is connected to the center of the movable gripping member 22 via a pin 25. It is pivotally connected to the vicinity of the club.

  In the grinder constructed as described above, the torsion bar 29 is set with an initial torsional deflection in the direction of the arrow B in the state shown in the drawing, and the restoring force of the torsion bar 29 causes the spring case 26 to move toward the arrow. A rotational torque in the A direction is generated. This rotational torque acts as a force in the direction of pushing up the vicinity of the central portion of the movable gripping member 22 from the arm portion 27 of the spring case 26 via the lever 28 and the pins 24 and 25. Then, by this acting force, the gripping portion 22a of the movable gripping member 22 is rotated toward the rope 10 side, and the cord 10 is firmly sandwiched between the gripping portion 21a of the fixed gripping member 21 and the gripping cord. To do.

  On the other hand, when releasing the rope 10, the roller 30 provided at the end of the movable gripping member 22 opposite to the gripping portion 22a is pushed downward against the restoring force of the torsion bar 29, This is done by rotating the handle 22a in the opposite direction of the rope 10.

  As described above, the gripping and releasing operations of the grinder 20 are performed by moving the roller 30 provided at the end of the movable gripping member 22 in the vertical direction, and this operation is performed. For this purpose, gripping rails 15 are fixed on the arrival side and departure side of the carriage 14 at the stop (see FIG. 1).

  FIG. 3 shows a part of the grip / release rail 15 and FIG. 4 shows a cross-sectional view of the grip / release rail. The grab rail 15 is fixed in the stop so as to abut the roller 30 of the grinder 20 from above along the traveling direction of the grinder 20, and the lower surface of the grab rail 15 is gripped. It is gently inclined in the vertical direction with respect to the traveling direction of the rope device 20. In FIG. 3, when the gripping machine 20 travels from the left direction to the right direction, the roller 30 is pushed down by the gripping and releasing rail 15 to release the rope 10. When the grinder 20 travels from the right to the left in the figure, the roller 30 gently rises along the inclination of the grab rail 15, and the grinder 20 gradually moves the rope 10 Can be seized.

  A part of the lower surface of the grip-and-shake rail 15 is cut out, and a spring force detecting device 40 is attached to this part. The spring force detection device 40 includes a detection plate 41 and a load cell 42. The detection plate 41 has thick portions at both ends and a thin portion at the center, and the lower surface of the detection plate 41 is attached to be continuous with the lower surface of the grip-and-shake rail 15 so as to be on the same plane. Yes. The load cell 42 is a thin-walled portion of the detection plate 41 and is firmly fixed to the surface on the back side of the surface with which the roller 30 of the grinder 20 abuts.

  The spring force detection device 40 configured as described above can detect the spring force of the grinder 20 passing through this position as described below. When the restoring force of the built-in torsion bar 29 acts on the roller 30 of the grinder 20 to generate a force to lift upward, the roller 30 is at a certain height. By measuring this pushing force, the restoring force of the torsion bar 29 can be known. In the spring force detection device 40, when the roller 30 of the grinder 20 passes through the detection plate 41, the pushing force of the roller 30 acts to cause distortion in the thin portion of the detection plate 41. Is detected by the load cell 42 and converted into an electrical signal. The relationship between the distortion of the detection plate 41 and the electric signal and the load applied by the roller 30 is calibrated in advance. Therefore, the pushing force of the roller 30 or the restoring force of the torsion bar 29, that is, the spring force is determined by the detected electric signal. It can be measured.

  Next, as shown in FIG. 5, an RFID tag 17 is attached to the transporter 14. The IC portion of the RFID tag 17 stores in advance carrier information for identifying the attached carrier, for example, a carrier number. The RFID tag 17 can be either an active tag that operates by receiving electricity supply or a passive tag that does not require electricity supply. The cable carrier 14 has a power supply. In many cases, it is preferable to use a passive tab. Alternatively, the RFID tag 17 may be housed in a case for preventing damage and attached to the transporter 14.

  On the other hand, the antenna 16 of the reader 18 for reading the information stored in the RFID tag 17 is fixedly installed in the stop at a position facing the RFID tag 17 with a certain distance. In this embodiment, the antenna 16 is installed at a position before the transporter 14 is turned from the arrival side to the departure side and is forwarded and accelerated (see FIG. 1). The speed of the transporter 14 passing through this position is as follows. Due to the low speed, information of the RFID tag 17 can be reliably read. Further, since the communication between the RFID tag 17 and the antenna 16 is performed by electromagnetic induction or wireless, it is not affected even if ice / snow or dirt adheres.

  Next, a computer 50 is installed in a driver's cab or the like in the stop, and the spring force of the grinder 20 and the carrier information of the carrier 14 are recorded, and the database 51 is configured by each data. .

  In the above configuration, data is stored in the computer 50 as follows. In FIG. 1, when the transporter 14 is routed from the arrival side through the stop and passes the position of the antenna 16, the transporter information stored in the RFID tag 17 attached to the transporter 14 is read by the antenna 16 of the reader 18. This data is transmitted to the computer 50. Next, when the transporter 14 is accelerated and passes through the grip and release rail 15, the spring force of the gripping machine 20 is measured by the spring force detection device 40 attached to a part of the grip and release rail 15. This data is transmitted to the computer.

  FIG. 6 is a chart showing an example of a format when the above-described transporter information and spring force data are stored in the database 51. First, when the computer 50 receives the carrier information, the carrier number is input to the database 51, and at the same time, the date and time are acquired and input by the computer 50. At this time, a count is added once as the number of times the container has passed. At this time, the number of times that the carrier has passed may be approximately counted as the number of times the gripping device 20 is grasped and released. Thereafter, when the grinder 20 passes through the spring force detection device 40 and information on the spring force is transmitted, the information is stored in the same record as the carrier No. input earlier in the database 51, and a set of these data is stored. Hold as. Thereafter, data is input and accumulated in the same manner for each of the transporters 14, 14,.

  The database 51 in which data is stored in this way can be statistically processed and output to a display, a printer, or the like at any time. For example, by displaying the data of a specific transporter 14 arranged in chronological order and analyzing the change in spring force, it is possible to know the degree of spring force of each transporter and formulate the spring replacement time in advance. Or abnormalities of the spring can be detected in advance. In addition, when performing maintenance by setting a limit on the number of grips and releases of the grinder 20, search the database for the number of times the carrier has passed or the number of grips and releases, and select the gripper 20 that is approaching the overhaul time. Is possible.

  As is apparent from the above description, the present invention makes it possible to always accurately grasp the state of the grinder 20 by processing various data stored in the database 51, Contributes to safe operation of The data format of the database 51 is an example and is not limited to the present embodiment, and may be changed depending on the necessity, importance, purpose of use, etc. of each data. And measurement data such as spring force information and time information related to the carrier may be stored in association with each other.

  Next, an embodiment different from the above embodiment will be described. In the above description, the RFID tag 17 stores the initial setting information as the carrier information, and the reader 18 reads the information. In the present embodiment, information from the database 51 is written to the RFID tag 17 each time the transporter 14 passes.

  First, similarly to the above, when the transporter 14 passes the position of the antenna 16, the transporter information is read and transmitted to the computer 50. In the computer 50, data is stored in a new record of the database 51, and at the same time, accumulated data of the passing transporter 14 is totaled and transmitted to the reader / writer 18. The reader / writer 18 transmits this accumulated data to the RFID tag 17 via the antenna 16 and stores it in the IC part of the RFID tag 17. In this way, the same data as the accumulated data in the database 51 is also stored in the RFID tags 17 of the individual carriers 14, 14,.

  With the above configuration, various data are held in both the database 51 and the RFID tag 17, so that even if one of the data is lost, it can be immediately restored. When a manufacturer or the like performs overhaul or repair of the grinder 20, the grinder 20 is collated with the RFID tag 17 removed from the carrier 14 of the grinder 20 in a factory or the like, and the RFID tag 17 is accumulated. Appropriate measures can be taken by analyzing the data.
