Automated railcar gate operating system
An automated trackside railed car discharge gate operating system is disclosed which can automatically unload a string of cars “on the fly” and without the need for a separate indexing system. The system includes a pair of carriage-mounted tool systems for opening/closing capstan-operated railcar gates disposed to travel along a carriage track and including visual devices that acquire and track capstans and coordinate tool orientation and operation.
1. An automated trackside railcar discharge gate operating system comprising:
(a) a railcar gate opening and closing arrangement comprising a pair of automated carriage-mounted capstan-operating tool systems for opening/closing capstan-operated railcar gates, said tool systems being disposed to travel along a carriage track and open and/or close moving capstan-operated railcar gates on moving railcars, said tool systems including systems to acquire, transmit and receive data, including data regarding capstan coordinates for each car to be processed, a capstan-operating tool and visual device to acquire and track capstans to coordinate tool operation;
(b) a railcar location feedback system separate from said railcar gate opening and closing arrangement and comprising a pair of carriage-mounted trackside feedback devices to coordinate railcar opening and closing operations, respectively, for detecting, being moved by, and communicating the location and movement of railcars to be processed, said device being disposed to travel along a feedback track; and
(c) a central data processor and control device that communicates with and coordinates operation of said tool systems and said feedback devices.
2. An automated system as in claim 1 including a device for reading railcar codes.
3. An automated system as in claim 1 wherein each said carriage-mounted trackside tool system operates in conjunction with a corresponding feedback device.
4. An automated system as in claim 1 wherein each of said vision devices of said tool systems includes a video camera with three-dimensional capability for recognizing a capstan height rotational position and lateral distance position a computer that enables said tool system to track said capstan.
5. An automated system as in claim 1 wherein said tool systems include means for aligning a corresponding capstan operating tool chuck with a recognized capstan rotational orientation.
6. An automated system as in claim 4 wherein said tool systems include means for aligning a corresponding capstan operating tool chuck with a recognized capstan rotational orientation.
7. An automated system as in claim 1 wherein each of said feedback device includes a deployable bogey frame engaging arm that pushed along by a railcar when it is deployed.
8. An automated system as in claim 1 wherein each of said feedback devices includes means for communicating required car locations and movement to said control data processor control.
