Description
Technical Field
The invention belongs to the field of automatic control, and particularly relates to an automatic distribution flow control method of an automatic material conveying vehicle.
Background
Generally, the flow control of the automatic material conveying vehicle is realized by using a Programmable Logic Controller (PLC). When the material conveying vehicle automatically operates, the no-load and load operation of logistics equipment on a production line is realized through 2 command buttons of 'calling' and 'waiting' arranged on stand columns of each station. When the production line has a plurality of stations and complicated interconnection, the material conveying vehicle is controlled only by the 'calling' and 'waiting' command buttons, so that the production line has low process flow efficiency, and even the complicated production line material operation is difficult to be safely and reliably executed.
Disclosure of Invention
In order to solve the defects of the prior art, the invention provides a method for controlling the conveying flow of an automatic material conveying vehicle, which can safely and reliably solve the problem of automatic material operation control on a complex production line.
In order to solve the technical problem, the invention is based on four control buttons for redefining logic actions and corresponding PLC control execution modes, and the specific method is as follows:
logical definition of (one) four buttons
The following steps of calling: the transfer cart in a command waiting state or a confirmation state corresponding to the previous process is operated to a station where the calling button is located;
"wait": the transfer cart (in no-load state) which has finished executing the task is commanded to run to a waiting position (each station has a waiting position, and when a waiting button command is executed, the cross beam of the transfer cart can automatically rise to the highest position);
"confirm": when the transport vehicle hangs the material (namely the load state) at the completion position, after a confirming button is pressed, other stations can use a calling command to transport the material to a designated station;
"complete": and (3) moving the transport vehicle in the load state to a completion position (each station has a completion position, and when a completion button command is executed, the transport vehicle in the load state can move to the completion position).
Number and mounting position of four kinds of buttons
The number of the calling buttons is determined according to the number of the material lifting points of the production line, and the waiting, confirming and finishing buttons consist of a group; the 'call' button is installed in the working area of the station, and the 'wait', 'confirm' and 'finish' buttons are installed on the automatic material conveying vehicle.
Through the logic combination of the four buttons, the logistics operation problem of a complex production line can be safely and reliably solved. Meanwhile, by arranging the buttons by using the control method, the operability of the equipment is higher.
Drawings
Fig. 1 is a diagram of a complex logistics layout involving two stations.
In fig. 1: 1. station 1, 11, position of a calibration piece, 12, position of a hanging beam, 13, position of a finished product, 2, station 2, 21 and position of a test bench.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to fig. 1, and it is obvious that the described embodiment is only a specific embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the complex logistics control with two stations is related, and the specific work flow is as follows: the transfer cart lifts by crane finished product to the finished product position at station 1's last station, the uninstallation finished product, the transfer cart lifts by crane the hanging beam, lift by crane on the basis that the hanging beam was hung to the transfer cart and reach the testboard, the testboard only places the marking, after the test was accomplished, the transfer cart lifts by crane marking to the marking position, only uninstallation marking, then remove to lift by crane finished product to the testboard again, only uninstallation finished product, after the test was accomplished, the transfer cart lifts by crane finished product to the finished product position, then the transfer cart is in hanging beam position uninstallation hanging beam, accomplish work.
In order to complete the above work control process, the four logic control buttons of the invention are adopted, and a PLC control method is designed as follows (station 1 is provided with 5 calling buttons and named according to the process characteristics, and station 2 is provided with 3 calling buttons and named according to the process characteristics):
product position 1: "call" - "wait";
the position of the hanging beam: "call" - "complete";
the position of the marking piece: "confirm";
test bench position 1: "call" - "wait" - "confirm" -;
test bench position 3: "Call" - "confirm";
the position of the marking piece: "call" - "complete";
product position 2: "Call" - "confirm";
test bench position 1: "call" - "wait" - "confirm" -;
test bench position 2: "Call" - "confirm";
product position 3: "call" - "complete";
the position of the hanging beam: "wait".
In the embodiment, aiming at the logistics characteristics between two stations in the production line, the PLC control scheme with only two control buttons obviously cannot realize the operation of materials, and the control method adopted by the invention adopts four logic control buttons, so that the flow control task can be effectively completed, the logistics operation problem of a complex production line is solved, and the operability of equipment is improved.
