Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
Refer to Fig. 1 and Fig. 2, it is a kind of label paper tape of the utility model synchronization conveying device, comprises frame 1, is arranged at the label machine 2 in frame 1, feedway 3, synchronizing controls and controller.
Described label machine 2 is for Print Label on blank tape and output label paper tape, this label machine 2 is existing mature technology, and can need according to client the label printing different content, be such as the label of Huawei's handset customization, or the label etc. of certain brand computer.
Incorporated by reference to consulting Fig. 3 and Fig. 4, described feedway 3 is installed in label machine 2 downstream, takes to front transmission for pulling label paper under the control of the controller; Particularly, described feedway 3 is provided with a monitor station 31, and the top of monitor station 31 is provided with a detection flat board 32; This detection flat board 32 is provided with the through hole running through plate face, low-pressure gas source is connected below detecting dull and stereotyped 32, concrete this low-pressure gas source is a vacuum generating device in the present embodiment, and this vacuum generating device produces vacuum, make air-flow above through hole toward current downflow, thus forming suction at the dull and stereotyped 32 upper surface places of detection, label paper tape is adsorbed in the process forwarded, thus is tightly attached at dull and stereotyped 32 upper surfaces of detection, guarantee the planarization of label paper tape, prevent wrinkling;
The rear and front end detecting dull and stereotyped 32 is respectively equipped with live-rollers 33, and the top surface of live-rollers 33 is concordant with the upper surface detecting dull and stereotyped 32, and during work, label paper tape is adjacent to live-rollers 33 outside face and forwards with the upper surface detecting dull and stereotyped 32; The below of monitor station 31 is provided with the driving rotating disk 34 for driving label paper tape to forward, and drive rotating disk 34 to be connected with drive motor, drive motor is controlled by described controller and can realizes label paper tape and forward with friction speed.
As improving further, one end of one of them live-rollers 33 described synchronously connects a rang sensor (not shown), particularly, this rang sensor is positioned at paper tape upstream end, this rang sensor is for measuring the transmission distance of label paper tape, and being provided with of this rang sensor is beneficial to the position that accurate abstract factory paper tape enters monitor station 31.
As improving further, described detection dull and stereotyped 32 is provided with the force fit plate 36 that can spin upside down, particularly, one lateral edges of this force fit plate 36 is articulated on this lateral edges of monitor station 31, thus force fit plate 36 can spin upside down around this edge, forms the passage of walking for label paper tape between this force fit plate 36 and detection dull and stereotyped 32, during work, this force fit plate 36 pushes down label paper tape from top to bottom, can prevent label paper band from occurring wrinkling further, guarantee its planarization.
As improving further, described monitor station 31 is also provided with a guiding roller 35, this guiding roller 35 is positioned at inside the below of the live-rollers 33 of label paper band upstream end; Label paper tape imports from upstream end, be close to the inner surface of guiding roller 35 and outwards pass, be close to the outside face of this end live-rollers 33 again, finally turn, forward along dull and stereotyped 32 upper surfaces of detection, this guiding roller 35 can make whole piece paper tape more tighten, prevent from occurring sliding phenomenon between paper tape and each surface, and then improve the stationarity transmitted.
Described synchronizing controls is between label machine 2 and feedway 3, it comprises swing span 7 and position transduser, swing span 7 is articulated in frame 1, specifically in the present embodiment, this swing span 7 is articulated in the side of monitor station 31 near label machine 2, the rectangular frame-like of described swing span 7, the lower end of framework is provided with transverse roller 71, and this transverse roller 71 is pressed against on label paper tape; The lower end (i.e. transverse roller 71) of swing span 7 is pressed against on label paper tape, and described position transduser is for detecting the swing position information of swing span 7 lower end; Described controller is used for the speed regulating label machine 2 and feedway 3 according to described swing position information.
The principle of work of this synchronizing controls is as follows:
When transfer rate faster than feedway 3 of the print speed of label machine 2, label paper tape between stream oriented device will accumulate, thus under the effect of swing span 7 self gravitation (weight of swing span 7 lower end is greater than the weight of upper end), label paper tape is pressed down formation " V " shape, both speed differences are larger, paper tape accumulation is more, and the degree of depth of " V " shape is larger; Now, the position of position transduser induction swing span 7 lower end (i.e. transverse roller 71), and position signal is passed to controller, the transfer rate of feedway 3 accelerated by controller through calculation process, or reduce the print speed of label machine 2, make the step of stream oriented device keep basically identical; When the print speed of label machine 2 is slower than the transfer rate of feedway 3, label paper tape between stream oriented device will reduce and tighten, make swing span 7 lower end is lifted, now label paper tape is in " one " shape, the position of position transduser induction swing span 7 lower end, and passes to controller by position signal, and controller slows down through calculation process the transfer rate of feedway 3, or accelerate the print speed of label machine 2, thus make the step of stream oriented device keep basically identical; The setting of this synchronizing controls can the speed of flexible label machine 2 and feedway 3, makes the two step keep basically identical, thus it is stagnant too much or the situation of pulling apart to prevent label paper tape heap, guarantees the smooth running of this detecting device; And be pressed against on label paper tape due to the lower end of swing span 7 always, can ensure the tight property that label paper tape remains certain to be conducive to the steady transmission of label paper tape.
In sum, the utility model by arranging synchronizing controls between label machine 2 and feedway 3, can the running velocity of both flexible, guarantee that the two acts in agreement, prevent from occurring the stagnant or tensile phenomenon of label paper tape heap between, simultaneously can ensure that label paper tape has certain tight property all the time in transport process, be conducive to the continuing of label paper tape, steadily carry.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
