According to actual production needs, a PLC part program wiring diagram designed by the applicant is shown in FIG. 7, a program flow diagram is shown in FIG. 8, and the PLC part program wiring diagram is mainly used for controlling a lifting platform, and a large amount of data are collected and then directly delivered to PC machine configuration software for use and processing.
The program main body is a sequence control structure and consists of three working steps of M0.0 (waiting), M0.1 (lifting) and M0.2 (check weighing).
After the system is started, the SM0.1 initialization pulse sets the program to the M0.0 position, at the moment, the coil Q0.0 is electrified, and the weighing platform is kept at a low position under the action of the plurality of pneumatic piston rods. When the goods move from the assembly line to the weighing platform, the photoelectric switches SQ1 and SQ3 are triggered in sequence, and the corresponding power-on delay timers T40 and T41 respectively count time until the goods completely pass through the photoelectric switch positions. The time counted by the timer is sent to a corresponding variable of the configuration script through communication through a V area of the PLC, and the configuration script solves the passing time of half the length of the goods according to a constant V (the moving speed of the goods on the conveying chain is approximately constant) (the average value of the two is used for ensuring accuracy). After the calculation is finished, the obtained value is sent to the V area of the PLC through communication, and the value is directly used as the timing duration of the timer T37. When the goods pass through the photoelectric switch SQ4 at the weighing platform position, the timer T37 starts timing, and after the timing is finished, the weighing platform supports the goods. At the moment, the center of the goods (gravity center) is basically ensured to be on the weighing platform, on one hand, the weighing precision is ensured as much as possible under the current hardware architecture, and on the other hand, the situation that the goods are turned over due to the fact that the gravity center deviates from the center of the platform when the weighing platform supports the goods is also prevented.
M0.1 is the lifting state of the weighing platform, and a T38 timer is adopted for delaying time to ensure that the pneumatic piston rod reaches the upper limit. The micro switch is not adopted, so that the number of PLC input points is saved, the complexity of a hardware system is reduced to a certain extent, and the fault rate and the cost of the hardware system are reduced. And M0.2 is used as a check weighing step and a weighing signal of the configuration program, and the configuration program can count the current flow number and the weight into a report when obtaining an M0.2 power-on signal. Since the minimum interval between two goods is 10s, in order to avoid physical collision by not affecting the check weight of the subsequent goods, the signal that the M0.2 check weight state jumps back to the M0.0 wait state is directly triggered by the delay of T39 without returning by the configuration program. And if the weight of the current goods is out of tolerance, the configuration software directly controls a buzzing alarm lamp in a Q area of the PLC through the weight detection of the I/O discrete quantity variable, and the sound-light alarm indication is carried out on an operator.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, but also to cover any modifications or equivalent changes made in the technical spirit of the present invention, which fall within the scope of the present invention.
