Abstract
The precision counter automatic checking device is formed from a general precision counter, a small overtravel-limit switch, a group of photoelectric sensors and a microcomputer (or PLC), in which the small overtravel-limit switch is positioned at coutner channel interface place, the photoelectric sensors are respectively positioned at two sides of waiting position of counter channel interface, the overtravel-limit switch, sensors and counter steps motor are connected with microcomputer by means of serial-parallel interface, and the interior of imcrocomputer is equipped with checking program. It can implement omnirange checking in the course of counting, and its accuracy is up to 100%.
Description
The invention belongs to calibration equipment, particularly a kind of calibration equipment of particle accurate counter.
Domestic common particle accurate counter is to adopt the method for stepper motor by the grain counting at present, and by Stepping Motor Control being reached the purpose of counting, this method is not carried out verification to count results, can't correct issuable error.
The purpose of this invention is to provide a kind of can be to the device of the automatic verification of counting process, make each link of counting process can be by verification, if error can be corrected.
The object of the present invention is achieved like this:
An automatic check device for accurate counter is made up of the logical accurate counter of a Daepori, little travel switch, one group of photoelectric sensor and a microcomputer (or PLC).It is characterized in that: little travel switch is positioned at place, counter passway, and photoelectric sensor is positioned at counter holding fix both sides, and travel switch, sensor, counter steps motor all link to each other with microcomputer by serial paralled interface, and checking routine is set in the microcomputer.
Microcomputer (or PLC) plug-in is:
(1) opening device makes photoelectric sensor in running order, makes the stepper motor reset to zero; From database, read
Go out count number;
(2) judge whether the sensor result is " nothing ", for " nothing " then enters (3), not for " nothing " is then advanced
Go into (4);
(3) open travel switch, judge whether the sensor result is " having ", as then advancing ' go into for " having "
(4), as be that " nothing " then continues to detect, repeat (3) or report an error;
(4) drive stepping motor scrapes particle;
(5) judge whether the sensor result occurs " nothing ", occur then from database, subtracting 1 and do (6) and declare
Disconnected; Do not occur then repeating (4) or reporting an error;
(6) treat in the judgment data storehouse whether count number is " 1 ", continue (4)-(5) when being not " 1 ";
Enter during for " 1 " (7);
(7) close upper stroke switch, repeat (4);
(8) judge whether the sensor result occurs " nothing ", occur then quitting work, then repetition (4) of appearance,
(8) or report an error.
Advantage of the present invention is to stop leak number, wrong number phenomenon, guarantees that count results 100% is accurate.
Below in conjunction with description of drawings embodiment:
Fig. 1: automatic check device for accurate counter front view;
Fig. 2: automatic check device for accurate counter vertical view;
An automatic check device for accurate counter is made up of the logical accurate counter of a Daepori, little travel switch, photoelectric sensor and a microcomputer (or PLC); Wherein travel switch 4 is positioned at counting channel mouth 6 belows, and the stroke lever top has a shift fork can insert the passway to block particle; Photoelectric sensor occupy the both sides, passway in 3 minutes, was as the criterion not block tablet counter scraping blade 2; The stepper motor 1 of travel switch, photoelectric sensor, several pieces devices all links to each other with microcomputer by serial paralled interface, the built-in counting of microcomputer (or PLC), checking routine.The program that is provided with in the microcomputer (or PLC) is:
(1) opening device makes photoelectric sensor in running order, makes the stepper motor reset to zero; From database, read
Go out count number;
(2) judging whether the sensor result is " nothing ", for " nothing " then enters (3), is not that " nothing " then
Enter (4), repeat (2) again or report an error;
(3) open travel switch, judge whether the sensor result is " having ", as then entering ' go into (4) for " having ",
As be that " nothing " then continues to detect, repeat (3) or report an error;
(4) drive stepping motor scrapes particle;
(5) judge whether the sensor result occurs " nothing ", occur then from database, subtracting 1 and do (6) and declare
Disconnected; Do not occur then repeating (4) or reporting an error;
(6) treat in the judgment data storehouse whether count number is " 1 ", continue (4)-(5) when being not " 1 ";
Enter during for " 1 " (7);
(7) close upper stroke switch, repeat (4);
(8) judge whether the sensor result occurs " nothing ", occur then quitting work, then repetition (4) of appearance,
(8) or report an error.Operating principle: when channel exit had particle, the light between the photoelectric sensor can be blocked; After the counting scraper plate was scraped, light can pass through, and illustrated that counting is effective.Travel switch blocks next particle in the passage, can make sensor arrive a last particle.Using method: operating personnel will intend count number input computing machine, and start-up routine gets final product then.Flow process general introduction: the present invention is general to be used with packaging machine, and many counters and a packaging machine are combined into system's use usually.
