Abstract

PURPOSE:To stabilize the starting interval of carriers with less disorder caused by slippage, etc., by acceleratingly transferring carriers by means of a linear motor when a counted value in which the fixed point of a rotating pulley is counted reaches a certain value. CONSTITUTION:The captioned device consists of a detecting portion 40 which generates signals by detecting the fixed point of a pulley which is rotated with a cable 32 being put around its peripheral edge, a control portion 50 which counts the signals and acts when the counted value reaches a certain value, a controlling portion 60 which makes carriers 6 started by means of a linear motor which is controlled by the control portion 50, and an acceleratingly transferring portion 70 which acceleratingly transfers the carriers 6 by means of the linear motor. As a result, since the linear motor is used in the acceleratingly transferring portion 70 for accelerating the carriers 6, the performance of starting and transferring of the carriers 6 is stabler, the delay of starting caused by slippage is less, and the carriers 6 can be started at a more accurate interval as compared with a device relaying on friction coefficient. The device is particularly effective for a carrier 6 with a large capacity.

Description

Detailed Description of the Invention (a) Purpose of the Invention [Field of Industrial Application] The present invention accelerates and launches a carrier using a transfer device using a linear motor in a terminal of a cableway, mainly an automatic circulation cableway. The present invention relates to a device for regulating the interval between carriage departures in cases where the vehicle is departed.

[Prior art] An automatic circulation cableway consists of a cable that is stretched and circulated between pulleys installed at terminals (stops, hereinafter the same) at both ends, and a cable gripping machine that suspends a carrier. It is well known that transportation is carried out by using a rope gripping machine to grip the rope.

In addition, within the terminal, the rope gripping machine that has left the cable is decelerated, forwarded, and accelerated by the transfer device to depart onto the cableway, and in this way, a plurality of carriers are circulated one after another. is being done.

In this way, the automatic circulation type cableway has the advantage that the cables, cable gripping machines, and carriers are removable, so the departure interval of the carriers can be adjusted to be closer or less dense depending on the size of the transport request. However, on the other hand, operating the carrier at intervals shorter than the specified limit is dangerous and must be avoided.

As a device for regulating the interval between departures of carriers, a device as shown in FIG. 10, for example, has conventionally been used.

A rail 101 is suspended at an elevated position within the terminal, and a plurality of tire wheels 102a, 102b are installed along the rail 101.
・102d are mounted in parallel and arranged in parallel. Further, a tire wheel 103 is pivotally installed near the tire wheel 102a, and is movable between an upper limit position and a lower limit position. The tire wheel 102a is rotated so that the speed of its peripheral edge is slow, and is hereinafter referred to as tire 102b.

102C... The peripheral speed of the last tire wheel 102e is made to become high in sequence, and the peripheral speed of the last tire wheel 102e is made to be approximately equal to the speed of the cable 104 described later.
Each rotation is given.

Similarly, the tire wheel 103 also has the tire wheel 10
Rotation is applied so as to have approximately the same peripheral speed as 2a. The cable 104 is guided from inside the terminal to the cableway line 106 through the vicinity of the cable gripping point 105. Further, a stopper 107 is provided between the tire wheel 103 and the tire wheel 102a, and the stopper 107 is operated in conjunction with the operation of the tire wheel 103, so that the rope gripping machine 11, which will be described later,
1 and a position that does not allow the rope gripping machine 111 to pass through. In addition, a sensor 108 is provided near the tire wheel 102a to detect that the rope gripping machine 111 has passed through the position.

On the other hand, the gripping rope t11111 is configured to roll on the rail 101 by running wheels 112, 112, and a carrier 114 is suspended from the rope gripping device 111 via a suspension device 113.

In the above configuration, if the conditions for starting the carrier 114 are not currently in place, the tire wheels 103 are at the upper limit position and the gripping line 4111 is not in place as shown in FIG.
3, and the stopper 107 is positioned so as to protrude into the travel path of the rope gripping machine 111 and prevent it from moving in the direction of the arrow 115. Therefore, the carrier 114 is stopped and ready for departure. It becomes.

During this time, the departure interval (described later) is being counted, and when the next departure conditions are met, a command is issued to control the tire wheels 103.
moves in the direction of arrow 109 and assumes the lower limit position, and the rotating peripheral edge of the tire wheel 103 comes into contact with the upper surface of the rope gripper 111, and starts frictional or adhesive transfer in the direction of arrow 115.

At the same time, the stopper 107 is retracted to a position that allows the rope gripping machine 111 to pass through. Next, the rope gripping machine 111 is transferred to the tire wheels 102a, 102b, .
06 direction. On the other hand, when the sensor 108 detects that the rope gripping machine 111 has passed the relevant position, the tire wheel 103 is raised to the upper limit position in response to a command, and the stopper 1
07 returns to the position where the rope gripping machine 111 is not allowed to pass. Therefore, at this time, even if a subsequent carrier approaches the tights wheel 103 position, it will be in a standby state and will not be able to depart.

On the other hand, from the time when the sensor 108 detects the passage of the rope grasper 111, a separate control device (not shown) counts the length of the cable 104 until the length reaches a predetermined value. Then, the subsequent carrier is started again in the same manner as above. In this way, the carriers are started one after another at predetermined intervals.

[Problems to be Solved by the Invention] The device as described above has been used in the past as a typical example of a carrier departure control device in the case of mechanically accelerated transport. However, since this device relies on the coefficient of friction between the eye wheel and the rope gripper, the performance of the friction transfer inevitably changes to some extent depending on the dryness and wetness of the friction surface. Tire wheels also wear out and must be considered as semi-consumable items. This tendency did not cause much harm in the case of conventional automatic circulation cableways that used lightweight carriers with a relatively small number of passengers, but in recent years, large carriers with a larger number of passengers have been used. However, in such cases, the inertia of the carrier is also large, which may cause a slip in the start of the transfer, resulting in a delay in the start of the carrier, and premature wear of the tires. This is likely to happen.

In addition, recently, the use of linear motors has generally been planned for transfer devices in terminals, but when such transfer devices are used, conventional friction-type devices are used in some places. Using , lacks consistency of design concept,
It is also inconvenient to handle.

This invention was made in view of the above-mentioned circumstances, and it is possible to stabilize the interval between carriage departures with less disturbance such as slipping, and to avoid using semi-consumable parts due to wear in the component parts of the device. Therefore, this invention is designed to provide a carrier departure control device that can be suitably adopted for cableways using relatively large carriers, and which is consistent in the configuration of equipment when a linear motor is used in the transfer device.

(B) Structure of the Invention [Means for Solving the Problem] In response to this purpose, the automatic circulation type cableway carrier departure control device of the present invention is provided with a device suspended between pulleys at terminals at both ends. A carrier departure control device for starting the carrier from the terminal in an automatic circulation cableway in which the carrier is operated by a gripping machine that suspends the carrier on a circulating cable, the carrier departure control device The device includes a detection unit that uses a sensor to detect a fixed point of a rotating pulley with the cable wrapped around its periphery and generates a signal, and an electric circuit that counts the signal and operates when the counted value reaches a predetermined value. The present invention is characterized by comprising a control section, a tube tfi1 section that is controlled by the control section and causes the carrier to start by a linear motor, and an acceleration transfer section that accelerates and transfers the carrier using the linear motor.

On the other hand, a transfer device, such as an acceleration transfer device, ie, an acceleration transfer section 70, through which the above-mentioned rope gripping machine 1 is transferred within the terminal, has the following configuration.

Rails 31, guide rails 12, and guide rails 13 are continuously suspended and fixed to the frame 11, which is fixedly suspended from the paper surface to the back of the paper in the figure. Here, the rails 31 are for guiding and rolling the running wheels 7, and the guide rails 12.13 are for guiding and rolling the running wheels 7.
This is to maintain the posture of the rope gripping machine 1 by rotating in an X direction, and to support an upward load based on the interaction of the linear motor 20. Further, a support beam 14 is fixedly and suspended continuously on the frame 11 along the traveling direction of the rope gripping machine 1 from the front side of the paper to the spine of the paper, and a primary coil 21 of a linear motor 20 is attached to this. A gap 23 is maintained between the cable gripper 1 and the secondary conductor 22 of the rope gripper 1.

With this configuration, the carriage 6 is moved by the interaction of the linear motors.

This is equivalent to the one proposed in the ``Cableway Carrier Cling Machine Transfer Device'' (Patent Application No. 192107 of 1988), which was filed on the same day. In addition, although it is generally advantageous to apply the above-ground method for transporting carriers within automatic circulation terminals, it is also possible to adopt the on-vehicle method depending on the conditions. As shown, it is also applicable to the on-vehicle-to-next method.

Here, the configuration will first be described in the case of the ground-level system.

FIG. 2 explains the basic configuration of the apparatus of the present invention.

First, in FIG. 2, this device includes a detection section 40 that detects the moving length of the cable and issues a pulse signal, and a control section 50 that counts the pulse signal and issues a command when it reaches a predetermined value.
and a control unit 60 that starts the carrier based on the command.
, and an accelerated transfer section 70 that accelerates and transfers the carrier.

FIG. 3 shows the configuration of the detection section 40 of the present invention. The cable 32 is wound around the pulley 41, and is driven or guided to turn. The pulley 41 includes one or more detection pieces 42a, 42b, and 42c.

42d is fixed in a protruding manner. On the other hand, a sensor 43 is provided at a fixed position. The pulley 41 rotates and the cable 3
2 is operated, the detection piece 42 rotates as the pulley 41 rotates.
a, 42b, .
detects this and emits a pulse signal. In the case shown in the third figure, four detection pieces 42a, 42b, . Therefore, it is detected that the cable 32 has been sent out by an amount equivalent to the circumferential length of the pulley 41. This configuration is
This structure is equivalent to that shown in Japanese Patent Publication No. 59-40666, but it is also possible to use the structure of ``Cable Movement Amount Detection Device for Cableway Pulley'' in Japanese Utility Model Application Publication No. 60-106869. Note that various types of proximity switches, photoelectric switches, limit switches, etc. can be used as the sensor 43.

Next, FIG. 5 shows the configuration of the control section 60 and accelerated transfer section 70 of the apparatus of the present invention.

As explained in FIG. 1, the rail 31 is supported by a plurality of frames 11, 11, etc. (not shown in FIG. 4) that are suspended and fixed to the terminal building, etc.
The cable 32 is stretched from inside the terminal, passing through the cable gripping point 33, toward the cableway track 34. Here rail 31
The primary coil 21a of the linear motor 20 is disposed near the departure standby position 61 along the line. Further, a stopper 63 is provided in the direction of the departure waiting position 61 toward the cableway track 34.
The stopper 63 can be moved to two positions: a position @ 63a that allows the rope gripping machine 1 to pass as shown in FIG. This is what was done. Further, in the vicinity of the departure standby position 61 and at a position along the rail 31 closer to the cableway line 34 than the stopper 63, a sensor 62 is provided to detect when the cable gripping machine 1 has passed through the position. .

Next, along the rail 31 from the vicinity of the departure standby position 61 to the vicinity of the rope grasping point 33, the linear motor 2 of the acceleration transfer section 70
0 primary coil 21b is provided.

The rope gripping machine 1 has a gripping part 3, and the rope gripping machine main body 2 has running wheels 7,
7, and is adapted to roll on a rail 31 with the running wheels 7, 7, and a carrier 6 is suspended from the rope gripping machine main body 2 via a suspension device 5.

Here, a secondary conductor 22 of a linear motor 20 is fixed to the rope gripping machine main body 2, and a required air gap 23 is secured between it and the secondary coil 21a. When machine 1 moves in the direction of arrow 35, primary coil 2
A gap 23 is ensured between each of them and 1b.

FIG. 6 shows the structure of the stopper 63. The stopper 63 is pivotally connected to a fixed pin 65 and has a hook-shaped portion 64 at its tip, and is movable in two positions, up and down, in the direction of an arrow 67 with the pin 65 as the center. When the solenoid 66 is energized, the stopper 63 assumes a position 63a shown by a solid line, and the hook-shaped portion 64 is retracted from the travel path of the rope gripping machine 1 to allow the rope grasping machine 1 to move forward. Further, when the solenoid 66 is de-energized, the stopper 63 descends to the position 1163b shown by the chain line and projects into the travel path of the rope gripping machine 1, so that it prevents the progression of the rope grasping machine 1. There is.

Next, FIG. 4 shows an electric circuit that is the control section 50. Here, the pulses emitted from the detection section 40 are counted by pulse counters p and c, and a command to operate the control section 60 is issued.

[Action J Next, the operation of this device will be explained.

During operation of the cableway, the pulley 41 at the terminal
rotates to drive or guide the cable 32. Pulley 4
Detection piece 42a disposed at 1.

42b...42d return to the sensor 43 position one after another,
When the light passes, the sensor 43 detects this, generates a pulse signal, and transmits it to the control unit 50.

Here, if the diameter of the pulley 41 is D, and the number of detection pieces 42a, 42t)... arranged on the pulley 41 is n, then after a - pulse is transmitted, the next pulse is transmitted. It is clear that the length of movement of the cable 32 until it reaches the end is ρ-π·D/n.

Next, in FIG. 5, the acceleration transfer section 70 is always in operation during the cableway operation. If the starting conditions for the preceding carrier (not shown) are now met and the vehicle is set off, the rope gripping machine will be moved by the linear motors 20 (21b, 22) of the acceleration transfer section 70.
), the vehicle grasps the cable 32 near the cable grip point 33 and departs in the direction of the cableway track 34.

During this acceleration elapsed period, when the sensor 62 detects the passing of the rope gripping device at this position, the power supply to the negative side coil 21a is cut off, and the stopper 63 becomes the position 1 [63b, which prevents the rope gripping I11. Become.

In FIG. 4, as described above, the sensor 5EN (62) detects the passage of the rope grasper 1. The A contact of sensor SEN is closed, and the relay RX is once energized.
The B contact of the relay MO is opened, and the relay MC, which had been self-holding, is demagnetized, and the A contact of the relay MO is opened, cutting off the current to the solenoid SQL (66), and the stopper 63 is lowered. Take position @63b and grab it! The posture is such that the passage of s1 is blocked. Similarly, when the A contact of the relay MC opens, the power supply to the primary coil LM1 of the tube IIJ section 60 is also cut off.

At the same time, the pulse counters p, c start counting the pulses transmitted from the detection unit 40 from the time when the 8 contacts of the previous relay RX are once opened and then closed again. Here, when the count values of pulse counters p and c reach a predetermined value, the A contacts of pulse counters P and C close, and the 8 contacts of relay RX are closed, relay MC is energized, and the relay Self-held by MC's A contact.

Furthermore, the solenoid SQL is connected by the other A contact of the relay MC.
(66) is energized, so that the stopper 63 assumes the upper position 63a and assumes a posture that allows the carrier 1 to pass. At the same time, another A contact of relay MC is closed, thereby energizing the primary coil 21a of the pipe product 60, and thus the carrier 1 is ready to start.

In this state, assuming that the carrier 6 and the grip line 1l11 are waiting at the departure standby position 61 or have entered the departure waiting position 61,
Due to the interaction between the secondary conductor 22 of the gripping rope I11 and the primary coil 21a of the control section 60, the rope gripping machine 2 is activated by the running wheels 7,
At 7, the robot is transferred along the rail 31 and transported by propulsion. Furthermore, since the primary coil 21b of the acceleration transfer device 70 is always energized during the operation of the cableway, the interaction between the secondary coil 21b and the secondary conductor 22 of the rope gripping machine 1 causes the am cable 1
is propelled and transported at an accelerated rate. In this way, the rope gripping machine 1 grips the cable 32 near the rope gripping point 33 and departs in the direction of the cableway line 34.

In the process of starting this carrier, the sensor 62
The stopper 63 closes due to the detection of
The power supply to a is cut off, and the pulse counters P, C, start new counting, and preparations are made for the departure of the following carrier.

[Example] In the above description of the configuration, a so-called ground-order system is used, in which the rope gripping machine 1 is provided with a secondary conductor of a linear eater, and the ground side is provided with a primary coil.

When used for transporting an automatic circulation cableway within a terminal,
The number of carriers used is large, the section requiring transportation is relatively short compared to other general railways, and
The ground-to-ground method is generally more advantageous because it is troublesome to transfer the mobile power supply by trolley, but in special cases such as when the number of carriers is small or when the transfer section within the terminal is long. In some cases, it may be more advantageous to use the so-called on-vehicle method, but even in that case,
The device of the present invention can be implemented.

FIG. 7 shows the basic relationship between the rope gripping machine 1 and the acceleration transfer section 93 when using the on-vehicle to next system. In the figure, parts that are equivalent to those of the on-board system shown in FIGS. 1 and 4 are given the same numbers. Here, a primary coil 81 of a linear motor 80 is fixedly attached to the upper surface of the rope gripping machine main body 2 of the rope gripping machine 1, and a support beam 1 on the ground side is attached.
A secondary conductor 82 is attached to the coil 4, and a gap 83 is maintained between the secondary coil 81 and the secondary conductor 82. In addition, a current collector 84 is provided extending from the rope gripping machine main body 2, and a trolley 85 is attached to the frame 11. In combination, a mobile power source is connected from the trolley 85 through the current collector 84. is supplied, and the negative side coil 81 is energized.

Using such a mutual relationship between the linear motors 80, in this embodiment as well, the detection unit 4
0, a control section 90, a control section 91, and an accelerated transfer section 93, and the parts that are different from the above embodiment are (
) is given.

First, as the detection section 40, a device completely equivalent to that shown in FIG. 3 is used.

Next, the control section 91 is shown in FIG. 9, and the ranges given the same numbers are equivalent to those shown in FIG. 5.

That is, the primary coil 81 of the linear motor 80 is provided on the upper surface of the rope gripping machine main body 2. Departure standby position 92
Nearby on the ground side, a secondary conductor 82a is arranged at a fixed position, and a trolley 85a is also arranged. Further, an accelerating transfer section 93 is provided along the rail 31 up to the vicinity of the rope grasping point 33. That is, a secondary conductor 82b of the linear motor 80 is disposed, and a trolley 85b is provided. Other stoppers 63. sensor 62
etc. are equipped in the same way as shown in FIG. 5 above.

Next, the control section 90 is shown in FIG. 8, and the parts given the same symbols as those shown in FIG. 4 have the same structure.

Here, the -next side coil LM1 (82a) is the trolley T.
LY, (85a, 84), and the next coil LM,2 (82b) is connected to the trolley TLY2 (85a, 84).
5b, 84).

Moreover, it is clear that the embodiment of the present invention in the case of the above-mentioned on-vehicle system also exhibits the same function and operation as in the case of the above-mentioned ground-side system.

(c) Effects of the invention As mentioned above, the conventional automatic circulation type cableway carrier departure control device has lI! This was due to friction transfer or adhesive transfer. This type of transfer has been widely used in the past due to its simple structure, but since it relies on friction, the transfer force or pushing force is more or less unstable depending on the condition of the contact surface. In particular, this tendency has become even more apparent in the case of large-capacity, permanent carrier cableways that use relatively large-capacity carriers, which have recently become a trend.

However, by using the apparatus of the present invention, these problems can be alleviated and the following effects can be enjoyed.

(a) Linear motors are used in the control unit that launches and starts the carrier, and the acceleration transfer device that accelerates the carrier, so the performance of carrier launch and transfer is more stable than devices that rely on friction coefficients, and the vehicle starts due to slipping. This reduces delays and allows the carriages to depart at more regular intervals. This is particularly effective for the largest carriers.

(b) Tire wheel wear does not occur in the case of abrasion transfer.

(C) When using the linear motor system for other carrier transfer devices in the terminal, the same configuration of the rope gripping machine can be used for continuous operation, and consistency of design concepts can be achieved.

(d) The linear motor system can be applied not only to the ground-based system but also to the on-vehicle system.

In addition, this device does not measure the departure interval by timing, but instead detects the length of the cable being let out in the detection section of the device, so it can be used for cableways where the operating speed is variable in multiple or stepless stages. It is also possible to accurately control the departure interval, which is effective for the safe operation of automatic circulation cableways.
