Background technology
At present, the holographic cover in location is imprinted on can only realize the transfer of unidirectional location on the reel stock, and promptly fixed-site, the content of hologram pattern on stock but is at random.Continuous cover printing device of the prior art mainly is to realize sheet-type printable matter (sheet-fed) continuous paper-feeding by a continuous paper-feeding mechanism is set, and realizes printing continuously with the reel anti false film.For example:
Publication number is that the Chinese patent of CN201169119 discloses a kind of unit type thermoprinting machine for reeled paper, is made of roll web unwinding device, paper storage device, thermoprint unit, tenslator, rewinding unit; Wherein the roll web unwinding device comprises roll web and motor; The paper storage device comprises the detecting sensor of deviation correcting device, swing arm, constant force device and deviation correcting device; The thermoprint unit comprises aluminium foil conveying device, aluminium foil, sensor, moving platform, motor, Paper tractor device and molding device; Tenslator comprises the detecting sensor and the constant force device of deviation correcting device, deviation correcting device; The roll web that rewinding is arranged in the rewinding unit can adapt to the thermoprint production after the web printing in enormous quantities effectively, enhances productivity effectively, shortens the production cycle of causing because of working procedures, reduces intermediate links such as management and dispatching, reduces production costs.
It exists main weak point to be: 1) hot stamping pattern is single, is not specific pattern, can not realize logistics chemical perm seal, can not realize the group formula thermoprint of many group coiled materials thermoprint simultaneously; 2) each thermoprint unit can only carry out thermoprint at a kind of pattern or a kind of size, and for the pattern not of the same race of specific factors of production or can only not finish by increasing many group thermoprint units during size of the same race, production efficiency is low, and the thermoprint deviation is big; A plurality of thermoprint units turn round simultaneously when 3) starting shooting, and the production cycle is long, and coiled material stock and aluminium foil are wasted bigger in process of production; 4) in the equipment running process, the aluminium foil after peeling off is not carried out effectively waste discharge rationally, finished product and useless paper tinsel are in the rolling simultaneously of same direction, and useless paper tinsel drops and causes decrease in yield easily, and with potential safety hazard.
Summary of the invention
The purpose of this invention is to provide a kind of equipment accurate between coiled material, continuous two-way holographic positioning overprinting of realizing, adopt the coiled material continuous feeding, discern, follow the tracks of by automatic deviation correction and photoelectricity reel stock and reel holographic anti-counterfeiting film, when realizing many group coiled materials, two-way location, accurately chromatography, also can supportingly finish the multiple membrane process of disposable group of formula, and can realize the automatic winding of reel stock, reel holographic anti-counterfeiting film and effectively waste discharge rationally.The present invention has not only realized the two-way positioning overprinting between coiled material, also be highly suitable for organizing the special chromatography demand for different chromatography sizes, different hologram patterns of formula logistics adhesive sticker sign, and chromatography is accurate, continuous, percent defective is low, thereby shortened the production cycle, reduced production cost effectively, greatly improved production efficiency, the autonomous anti-counterfeit recognition function of consumer for product also is provided.
The present invention adopts following technical scheme:
A kind of group of two-way holographic positioning overprinting machine of formula logistics, it is characterized in that, described chromatography machine is made up of unwinding device, photoelectricity identification control device, automatically controlled base, draw-gear, cover printing device, wrap-up, retractable winding apparatus and automatically controlled base are integral structure, the cover printing device is positioned at automatically controlled base top, the retractable winding apparatus is positioned at cover printing device both sides, is provided with the photoelectricity identification control device before the cover printing device, and matches with unwinding device;
Described unwinding device is made of one group of reel stock unwinding device and many group reel holographic anti-counterfeiting film unwinding devices, every group of corresponding one group of photoelectricity identification control device of unwinding device, many group reel holographic anti-counterfeiting film unwinding device modes that unreel independently unreel for each group, and group preface Pareto diagram is corresponding one by one with the reservation chromatography zone of reel stock.
The concrete structure of equipment of the present invention is:
Reel stock unwinding device unwinding device is made up of gas expansion shaft and automatic deviation rectifying device, and automatic deviation rectifying device is positioned at after the axis calibration, and the reel stock is carried out located lateral;
Reel holographic anti-counterfeiting film unwinding device is made up of unreeling shaft and locating wheel, and unreeling shaft has a plurality of stations that unreel, and each unreels the station correspondence one group of locating wheel is set, and locating wheel carries out located lateral to the reel holographic anti-counterfeiting film;
Described photoelectricity identification control device is the photoelectricity identifier, and it carries out longitudinal register to reel stock and reel holographic anti-counterfeiting film;
Described draw-gear comprises axis calibration, tension controller and axis to pull paper, and its effect is to even up the reel stock and make it reach;
Described wrap-up is made up of magnetic powder cluth and Scroll, to the rolling of reel finished product.
Described chromatography machine downstream connects multiple film device, after chromatography finishes, can the multiple membrane process of supporting disposable intact burst-oriented, that is: and can carry out the multiple film of axial location to single group or many groups.。
After overlapping printing device, angle conversion device is set,, adjusts position and the trend of peeling off the back anti false film by this device, the potential safety hazard that has caused when having avoided approaching or having moved towards consistent with the stock position, and improved yield rate.
Advantage of the present invention is:
1) adopt many groups independently to unreel mode, holographic anti-counterfeiting film unreels with stock and moves towards consistent when chromatography, has solved chromatography problem on deformation in the prior art, has improved the yield rate of product simultaneously.
2) adopting the reel holographic anti-counterfeiting film to be many groups unreels, and group preface Pareto diagram is corresponding one by one with the reservation chromatography zone of reel stock, can realize a chromatography moulding of multiple pattern, effectively solving when increasing a plurality of hot stamping unit in the existing technology to increase the situation that a plurality of thermoprint units are finished, thereby effectively reduces the waste of investment in production equipment and material.
3) can realize accurate between coiled material, continuous two-way holographic positioning overprinting.
