Description

[Detailed Description of the Invention] This invention relates to a freight car acceleration/deceleration device for controlling the speed of freight cars in a freight car yard.

A conventional device of this type is shown in FIG.

FIG. 2 shows a cross section taken along the line AA in FIG. Although only three sorting lines are shown in FIG. 1, in an actual rail yard, there are dozens of sorting lines starting from the parking lot.

In the following explanation, the auxiliary symbols of lowercase alphabets attached to the component devices are added to distinguish between the sorting lines.

Therefore, in the following explanation, what is common to all sorting lines will be explained without adding auxiliary symbols.

In the figure, 1 is a main line rail, 2 is a guide rail, and 3 is an acceleration/deceleration force that transmits acceleration/deceleration force to the freight car, so that it can run between the main line rail 1 and the guide rail 2.

Reference numeral 4 is an acceleration/deceleration roller having an acceleration/deceleration rate of 3, which has a structure that allows control of loading and unloading.

5 represents a freight car wheel.

When the acceleration/deceleration roller 4 is extended, this acceleration/deceleration roller 4
is in contact with the flange of the freight car wheel 5 to transmit acceleration/deceleration force to the freight car wheel 5.

On the other hand, the acceleration/deceleration roller 4 has a structure that allows the freight car to pass above the acceleration/deceleration rate 3 without any hindrance in the retracted state.

6 is a wire rope that transmits force at an acceleration/deceleration rate of 3.
connected in a loop.

Reference numeral 7 denotes a driving pulley, which transmits acceleration/deceleration force to the wire rope 6. Reference numeral 8 denotes a tensioner, which applies tension to the wire rope 6, and is composed of a pulley, a spring, and the like.

9 is a motor that rotates the drive pulley I, 10 is a motor 9
This is a control device that controls the

11 is a point, which changes the destination of the freight car.

Next, the operation will be explained.

First, the drive boob 97 is rotated so that the vehicle travels at a constant acceleration/deceleration rate 3 (referred to as conveyance speed).

Here, when each acceleration/deceleration rate 3 on the left side (or right side) reaches the terminal end of each section in the conveyance direction, each acceleration/deceleration rate 3 on the right side (or left side) reaches the starting end of each section at this point. However, at this time, the drive pulley 7 is reversed.

By repeating such running and reversing, each adjustment vehicle 3 will become
You can go back and forth between each section.

Further, the acceleration/deceleration rollers 4 take out only those of the acceleration/subtraction vehicle 3 that are moving in the conveyance direction, and retract the remaining ones.

On the other hand, point 11 is switched depending on the destination of the freight car, and the freight car is transferred to enter each sorting line.

The wheels 5 of the approaching freight car collide with the acceleration/deceleration rollers 4 and acceleration/deceleration force is transmitted thereto.

Acceleration and deceleration forces are applied to freight cars at a time when their speed becomes the transport speed.

After the speed of the freight car reaches the transfer speed, only the acceleration force necessary for the transfer is applied to the freight car.

The control device 10 thus rotates the motor 9 forward and reverse, and also controls its speed and torque.

As described above, the conventional freight car acceleration/deceleration device has a drawback that it is expensive because a control device is provided for each sorting line.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above.

Focusing on the fact that freight cars that must be accelerated or decelerated are rarely present on many sorting lines at the same time, a single control device is used to drive the acceleration/subtraction cars on multiple sorting lines. The purpose is to provide an inexpensive freight car acceleration/deceleration device.

Hereinafter, FIG. 8 showing an embodiment of this invention will be explained.

FIG. 3 shows, as an example, a case where six drive mechanisms are controlled by three control devices.

Note 1. The same reference numerals as in FIGS. 1 and 2 indicate the same or equivalent names.

9a to 9f are motors provided corresponding to each of the six drive mechanisms, IOA to 10C are three control devices, and 11a to 1
1f is a selection circuit including a relay electromagnetic contactor provided corresponding to each of the six drive mechanisms, and 12 is a management control device that monitors or controls the entire system.

The management control device 12 is composed of a microcomputer, etc., and is designed to receive signals from a freight car entry detector (not shown), etc., and can grasp which sorting line a freight car is currently on. Based on this, a command is issued to the selection circuit 11 to allocate and connect the control devices 10a to 10c to predetermined three of the motors 9a to 9ft,
Freight car adjustments are made for the assigned sorting lines.

The operation of this device will be explained below.

For example, when a freight car enters the sorting line and the motor 9b must be controlled, a command is sent from the management control device 12 to the selection circuit 11b, and the control devices in the Ready state, for example, the control device 10a and the motor 9b, are to control the motor 9b.

Next, when a freight car enters another sorting line d and the motor 9d is to be controlled, another control device in the Ready state, for example 10b, is connected to the motor 9d, and the motor 9d is controlled in the same manner as described above. .

Next, suppose that the control of the motor 9b is no longer necessary.
The management control device 12 sends a command to the selection circuit 11b to open the connection between the control device 10a and the motor 9b.

The motor 9d is similarly controlled.

In this way, the management control device 12 sends a command to the required selection circuit 11i corresponding to the sorting line 1, and plays the role of connecting the required motor 91 to be controlled and the control device 10j in the Ready state.

As described above, the freight car adjustment device according to this invention is provided with a selection circuit between the drive device provided corresponding to a plurality of sorting lines and the control device that controls it, and selectively switches between the control device and the drive device. Since it is possible to connect a plurality of drive devices with a smaller number of control devices, there is an effect that the freight car adjustment device can be constructed at a low cost.
