A kind of bar code printerTechnical field
The utility model relates to a kind of printing device, particularly relates to a kind of bar code printer.
Background technology
Bar code printer is a kind of special printer, is mainly used in the printing of bar code.In the prior art, bar code printer prints label, only could find when artificial labeling whether label has breakage or print bad phenomenon, but whether cannot detect the content printing bar code correct, cannot to the bar code information collection of printing, check, detect bar code whether qualified.Therefore, print underproof bar-code label if had, bar code barcode scanning mistake will be caused or cannot scan out, affecting selling or detecting of product.
Summary of the invention
The utility model object is to provide a kind of bar code printer, by using this structure, improves the accuracy that bar-code label prints.
For achieving the above object, the technical solution adopted in the utility model is: a kind of bar code printer, comprises printer body, and described printer body is provided with bar-code label outlet, described bar-code label exit arranges gripper shoe, and bar-code label supports through described gripper shoe; One scan rifle is also provided with, in the scan camera shooting head of the described scanner gripper shoe just to described bar-code label exit directly over the outlet of described bar-code label.
In technique scheme, described bar-code label is sent through described bar-code label outlet, and sends printer body through described gripper shoe.
In technique scheme, the scan camera shooting head of described scanner is just to the bar-code label in described gripper shoe.
In technique scheme, described scanner is provided with a scan camera shooting head.
In technique scheme, described scanner is provided with 2 ~ 3 scan camera shooting heads, described scan camera shooting head is arranged side by side along the direction of motion of described bar-code label.
In technique scheme, described scanner is connected with the controller of described printer body.
In technique scheme, described scanner place is provided with tag triggers sensor, and described tag triggers sensor is connected with described scanner.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1. the utility model arranges scanner above the bar-code label exit of bar code printer body, by the bar code on scanner scanning barcode label or Quick Response Code, whether the bar-code label printed for detector bar code printer is qualified, compared with the structure of no-raster rifle in the past, effectively can detect that whether the bar code content on the bar-code label that bar code printer prints is qualified, can effectively gather and check bar code information, improve the print quality of bar code printer;
2. the utility model structure is simple, is easy to realize.

Wherein: 1, printer body; 2, bar-code label outlet; 3, gripper shoe; 4, bar-code label; 5, scanner.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: shown in Fig. 1,2, a kind of bar code printer, comprises printer body 1, described printer body 1 is provided with bar-code label outlet 2, described bar-code label exports 2 places and arranges gripper shoe 3, and printer body 1 is for printing bar-code label 4, and bar-code label 4 supports through described gripper shoe 3; Also be provided with one scan rifle 5 directly over described bar-code label outlet 2, the scan camera shooting head of described scanner 5 just exports in the gripper shoe 3 at 2 places described bar-code label.
Described bar-code label 4 is sent through described bar-code label outlet 2, and sends printer body 1 through described gripper shoe 3.Described scanner 5 is provided with a scan camera shooting head, the scan camera shooting head of described scanner 5 is just to the bar-code label 4 in described gripper shoe 3, and described scanner 5 place is provided with tag triggers sensor, described tag triggers sensor is connected with described scanner 5, when there being bar-code label 4 to send from bar-code label outlet 2, tag triggers sensor sensing, and by information feed back to scanner 5, scanner 5 is started working, the information on scanning barcode label 4.When scan be bar code time, directly read bar code information, when scanning be Quick Response Code time, reading while Quick Response Code, also will read the character information below Quick Response Code, both check correctly, just pass through.
In the present embodiment, described scanner 5 is connected with the controller of described printer body 1, when the information of the defective or bar-code label 4 of information that scanner 5 reads read not out time, then whether scanner is by information feed back to printer body 1, controlled to work on by printer body 1.Thus operating personnel can know that whether the bar-code label 4 that bar code printer prints is qualified.
Embodiment two: a kind of bar code printer, in the present embodiment, its structure and embodiment one basic simlarity, difference is: described scanner is provided with 2 scan camera shooting heads, 2 described scan camera shooting heads are arranged side by side along the direction of motion of described bar-code label, scanner can scan 2 bar-code labels simultaneously, and scan efficiency is high.
Embodiment three: a kind of bar code printer, in the present embodiment, its structure and embodiment one basic simlarity, difference is: described scanner is provided with 3 scan camera shooting heads, 3 described scan camera shooting heads are arranged side by side along the direction of motion of described bar-code label, in the present embodiment, scanner can scan 3 bar-code labels simultaneously, and scan efficiency is high.
