WL99-Ⅲ Bagged Cement Counter

 

WL99-Ⅲ Bagged Cement Counter --- the first brand of counters for China cement industry.

WL99-ⅢBagged Cement Counter is a kind of automatic instrument used for the exact counting of bags of cement passing the belt conveyor. The instrument is adopted with the techniques such as the control of single chip microcomputer (SCM), set up of digital switch, luminance LED display and photoelectric isolation of counting signal, etc. featuring of strong anti-interference, precise counting, high speed and durability, and this instrument applies to be used for reminding of the quantity for loading the vehicle and counting the total amount of production, etc. Compared with conventional counter of cement bags, this bagged cement counter possesses more precise and quick counting function and high reliability due to the use of “the method of irregular continuous cement bags compensation” and “the method of two-pass belt speed compensation”.

Take a cement factory with annual production capacity of one million ton for example, 0.5% error equals 100000 cement bags (1000000 ton * 20 bag * 0.5%); based on 10 yuan of each bag of cement, the annual loss will be one million yuan for this error, which are beyond doubt huge losses for cement manufacturers and may reduce enterprise credit and client trust.

For this problem, through research on the characteristics of belt conveyor and analysis of the cause of error, WL99-Ⅲ bagged cement counter is designed with “the method of two-pass belt speed compensation” for intelligent fuzzy optimization process of the detected cement bags, which effectively absorbs redundant interference signals and is intelligent to identify continuous cement bags and small stacking bags to achieve precise counting of cement bags passing the belt conveyor.  

Features:

1.         Special for cement factory with easy and convenient operation.

2.         Precise counting, high speed and durability

3.         Available for single bag counting, continuous bags counting and batch counting.

4.         Intelligent to identify continuous cement bags with “the method of two-pass belt speed compensation”.

5.         Intelligent to identify small stack bag with “the method of irregular continuous cement bags compensation”.

6.         Photoelectric isolation of signals and strong anti-interference

7.         Storage function in case of power off to prevent data loss.

8.         Elegant appearance, available for external connection with several large screen displays. 

Function and purpose:

1、              Single bag counting: available for automatic absorption of interference pulse on cement bags and belt for precise counting. 

2、              Continuous bags counting: set normal parameters of each bag so that the number of continuous bags can be identified intelligently according to the parameters of a single bag.

3、              Batch counting: available for setting and displaying the number of single bags (0-60000); when the number reaches the setting value, counter will output flash alarm signal “AL” and a set of switching control signals (5A).

4、              When the counting number reaches the setting value, counter will be reset automatically or manually; then input code to reset counter according to requirement. 

5、              Advanced alarm before reaching the setting value for batch: the bags before alarm can be set by inputting code according to requirement.

6、              Accumulation of total number: check the total number of counts (0-9999999) (reset by inputting code)

7、              Malfunction alarm: when inductive head is detected abnormal or continuous bags exceeds 10 bags, the counter will send a set of relay switching signals for alarm (5A); this switch can connect to alarm bell or stop belt. 

8、              Automatic Control: Relay switching signals can realize automatic control of the secondary circuit of packaging line. (Such as control packing machine, belt, pushing machine and loader as well as connect to alarm bell etc.)
