This is a programmable controller that converts the signals into signals and outputs the signals to the driving device 6 and the brake 8 respectively.

FIG. 7 is a diagram showing an operation speed pattern showing an example of an operation state from the foot of a ropeway carrier to the top of a ropeway. In the figure, the vertical axis is the transport speed of the ropeway,
The horizontal axis is the position of the transporter. 16 is a creep speed set at the time of departure / arrival of the transporter, 17 is a constant speed of the preselected transporter, 18, 19, 20, and 21 are positions 22,
The transport speed limits corresponding to 23, 24 and 25, respectively, which are detected by the respective voltage relays 10, 11, 12, 13 respectively.

Next, the operation of the conventional ropeway control device configured as described above will be described. The constant speed 17 of the carrier is selected in advance by the speed selection switch 1 and transmitted to the programmable controller 15, and the programmable controller 15 stores the operation speed pattern of FIG. First, in the automatic operation, the automatic operation switch 2 is pressed, and the speed corresponding to the moving position detected by the synchro transmitter 4 is derived by the programmable controller 15 based on the operation speed pattern of FIG. 7 and output to the drive unit 6 as a speed reference signal. I do.

Then, power is first supplied from the driving device 6 to the motor 7 with the brake 8 applied so that the speed of the transporter becomes the creep speed 16, and the torque value of the motor 7 with the brake 8 applied is provided. Is creep speed 1
After confirming that the torque value corresponding to No. 6 has been reached, the signal is output to the programmable controller 15 and after the programmable controller 15 receives the signal, the release signal is output to the brake 8 and the brake 8 is released. Be driven. When the constant speed 17 is changed by the speed selection switch 1 during operation, the programmable controller 15 obtains an operation speed pattern based on the changed constant speed 17, and outputs a speed reference signal along the operation speed pattern to the driving device. 6 and the transporter is operated according to this operation speed pattern.

The deceleration of the transporter starts from the deceleration start position on the operation speed pattern corresponding to the constant speed 17 along the operation speed pattern. Then, when the transporter enters the position of the stop limit switch 3 in the stop, the transporter stops and the stop limit switch 3 is turned on. Then, the position data detected by the synchro transmitter 4 when the stop limit switch 3 is turned on is preset.

The automatic operation has been described above. Next, the operation at the time of semi-automatic operation will be described. First, by tilting the master controller 14 at a desired angle, a speed corresponding to the tilt angle is transmitted to the programmable controller 15, and the programmable controller 15 outputs a speed reference signal to the drive device 6 in response to a signal from the master controller 14. . Then, the transporter is operated under the same control as in the automatic operation. However, at this time, the speed of the operation speed pattern set by the programmable controller 15 is set as the maximum speed, and the speed set by the master controller 14 is adjusted so as not to exceed this maximum speed.

If the deceleration of the transporter is performed in the same manner as in the automatic operation, the operation efficiency deteriorates.
No. 295, first, each voltage relay 10,
A point is provided for each transport speed level set in 11, 12, and 13. The transport speed of the transporter is detected for each point, and it is determined whether or not each transport speed level has been reached. If so, deceleration is started from that point along the angle of the operation curve. When the carrier reaches the position of the stop limit switch 3 in the stop, the carrier stops and the stop limit switch 3 is turned on.
Then, the position data detected by the synchro transmitter 4 when the stop limit switch 3 is turned on is preset.

[0010] The collision avoiding area shown by the hatched portion shown in FIG.
The transport speed detected by each of the voltage relays 10, 11, 12, 13 at 4 and 25 is the transport speed limit value 18, 19, 2.
It is set so that if it exceeds 0 or 21, it is judged as abnormal and an emergency stop is performed. When the transporter stops at a place other than the stop, the operation is restarted according to the operation speed pattern even during the semi-automatic operation.

[0011]

Since the conventional ropeway control device is constructed as described above, the deceleration of the semi-automatic operation is controlled by each of the transport speed levels set by each of the voltage relays 10, 11, 12, and 13. A point is set for each of these, and when the transporter reaches this point, the transport speed is detected and it is determined whether or not to decelerate.If the operating efficiency is poor and the operating efficiency is to be improved, the transport speed is further increased. The level must be divided into a number of stages, and each stage must be provided with a number of voltage relays, resulting in high costs. In addition, the emergency stop of the transporter is set at each of the preset positions 22, 23,
The speed is checked at 24 and 25, and the positions 22 and
The speed at 23, 24, 25 is the limit 18, 19, 20,
Since the emergency stop is performed according to the determination as to whether or not the number exceeds 21, safety is deteriorated. Further, at the time of semi-automatic operation, since the control is performed by the master controller 14, the apparatus becomes expensive. Also, when the transporter stops at a place other than the stop and resumes operation, even if it tries to operate according to the operation speed pattern, if the position data is random at the time of the stop, the operation can be performed according to the operation speed pattern. Safety is an issue. Further, since the motor 7 confirms that the torque value corresponding to the creep speed 16, that is, the current corresponding to the creep speed 16 flows, the brake 8 is suddenly released, so that a large swing occurs in the transporter. In addition, since the preset of the position data of the synchro transmitter 4 is performed only by the operation of the stop limit switch 3 which is turned on when the carrier is stopped, for example, when the stop limit switch 3 is erroneously operated for maintenance or the like and turned on, the carrier is stopped. There was a problem that the position data was preset even when not in the field and the security was poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a ropeway control device capable of improving operating efficiency, improving safety, reducing swing of a transporter, and reducing the cost of an apparatus.
