The bar code detector of a kind of anti-weight, leakproof
Technical field
The utility model relates to the bar code detector device, relate in particular to a kind of can in case repeat, the bar code detector of leakproof sign indicating number.
Background technology
Along with being extensive use of of bar-code label, all use bar code in a lot of products, make that the management of bar code and application are more and more wider, obtain corresponding information by the scanning of relevant bar code, and then carry out the quality tracing of production control and final products.But the repeated code that often occurs in the reality taking place in the bar code printing, leak phenomenon such as sign indicating number, idle bit and can not in time find correction, for the repeated code stopping to take place in the bar code printing, leak bad phenomenon such as sign indicating number, idle bit and cause the inconvenience and the complaint of client's use side, therefore, be necessary to develop a kind of multi-functional bar code detector to solve above-mentioned technical matters.
The utility model content
The utility model provides a kind of bar code that can prevent to repeat, leak the bar code detector of phenomenons such as sign indicating number and idle bit for solving above-mentioned technical matters.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: the bar code detector of a kind of anti-weight, leakproof, wherein: comprise two axles that can put bar code volume, with one described a motor that is connected and a tag detection device that is connected with this motor.
Wherein, described tag detection device comprises label inductor and demoder.
Wherein, be provided with a storer, an arithmetical unit and control circuit in the described tag detection device.
Wherein, also include a warning device that is connected with described tag detection device.
Wherein, described tag detection device is provided with a plurality of function control buttons.
Wherein, but also comprise the evener of two balance bar code bands.
Compared with prior art, the utility model is prevented detection and function of statistic analysis such as repeated code, anti-idle bit, anti-frame hopping, figure place control, check bit checking by tag detection device (comprising label inductor, demoder, storer and arithmetical unit etc.) to the bar code band that produces, if in testing process, find the unusual of above phenomenon, warning device is the bright and warning of sounding with red light, stops testing automatically and reminds the staff simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is the synoptic diagram of the utility model preferred embodiments;
Embodiment
A kind of anti-weight, the bar code detector of leakproof, preferred embodiment as shown in Figure 1, it includes two axles 2 that can put bar code volume 1 (the bar code volume is for being rolled into without the bar code band of cutting off 5), a motor that is connected with one of them and a tag detection device 3 that is connected with this motor, tag detection device 3 comprises label inductor 31 and demoder 32, be provided with storer in the tag detection device 3, arithmetical unit, other device (not shown) of control circuit and realization measuring ability, also being provided with a warning device 6 is connected with tag detection device 3, tag detection device 3 is provided with a plurality of function control buttons and is used for control detection work, two eveners 4 are used for balance bar code band 5, make the bar code band even up tension make easy to detect accurately.
Tag detection device 3 is connected with computer, that use with the supporting exploitation of this bar code detector and automatically the software of statistics and analysis be used to handle detected corresponding data, by showing corresponding situation by computer behind the software analysis, the result is issued other department correct.
In use, bar code volume 1 to be detected is buckled on the axle 2 that does not connect motor, on two eveners 4, bar code band to be detected is placed on the below of label inductor 31 and demoder 32 with the bar code band, and an end fastening of pulling out the bar code band is on the axle 2 that is connected with motor.
The utlity model has following function, anti-repeated code detects: detected information compares verification by the arithmetical unit and the data of the networking shared database of input in advance and judges the result; Anti-idle bit detects: when detecting label and do not have bar code information is blank tag; Anti-frame hopping detects: press serial number and detect, prevent to lack certain sequence number label; Figure place control: prevent less or capacity exceeding number; The check bit checking detects: whether the check bit of pressing coding requirement is consistent; Function of statistic analysis: calculate the number number that lacks by the arithmetical unit statistical magnitude, by serial number.
When tag detection device 3 has detected above-mentioned abnormal conditions; can make warning device send sound or light prompting staff and shutdown by control circuit; or do not shut down and preserve automatically corresponding data when running into abnormal conditions and get off to deposit in the database and extract by the staff by the setting of function control button; after supporting software processes, the corresponding data of detection can show by computer.
Abovely the utility model is specifically described, but those skilled in the art can make numerous variations or variation to these embodiments these changes and changing within the scope that should fall into the utility model protection in conjunction with better embodiment.
