Description
Technical field
The utility model relate to a kind of supervisory system for the continuous feed printed medium optical sensor, comprise the supervisory system of this optical sensor and the handling machine that comprises this supervisory system.
Background technology
As everyone knows, a plurality of industrial processes all will design the processing operation that material medium begins of preprinting from circulation form, describedly preprint the form that material medium is generally band (tape), bar (strip) or band (band), the described material medium of preprinting is usually by using roller (actuated roller) continuous feed that suitably activates.For example, this medium can comprise: the packaging film that is used for making bag or packing; Paper tape; Maybe will be for the continuous label band of required product.
For example, known roll-type feeding price labeling wherein provides motion by travelling belt (being also referred to as carousel) for the container that must apply respective labels, contacts with the labeling unit with Bedpan.This labeling unit comes to limit from spool towards travelling belt and the motor-driven path of moving containers for the label band by the suitable roller by electromechanical actuation.Usually, the label band is at first by suitable cutting tool cutting, and the single label that is cut thus applies by utilizing so-called vacuum drums technology to be adhesive on the container.
Obviously, must fully accurately know medium with respect to the position of described mechanism at the operation requirements that the continuous feed medium carries out, described mechanism processes operation under suitable control.Processing can be: with predetermined pitch cutting medium (for example, being used for limiting single label or packing, perhaps in the general purpose single bit unit with Len req (unit element) that will be further processed); Printed data on the predetermined portions of medium (for example about valid period); Or splice terminal part in the situation of launching to finish at the spool of medium.
For this reason, for example in calibration with regulate the Complete Synchronization that obtains in the step of machine to be used between the mechanism of move media and the mechanism for the treatment of medium be inadequate, because the scrambling that during processing, may operate; For example, medium may print irregular, or the traction that may apply along with actuation roller and stretch or shorten, thereby produces the error of cutting, printing, splicing etc.
For this reason, advised using the supervisory system for the continuous feed printed medium, the location (or absolute phase) with monitoring process period allows to remedy possible scrambling thus.
These systems use symbol or the mark at the desired zone place that is positioned at medium usually, such as the starting point of the terminal and follow-up unit element that is positioned at unit element (label, packing etc.).These systems also use suitable optical sensor, the control module that described optical sensor is suitable for identifying these symbols (and location of therefore identifying move media) and suitable signal is sent to machine, in order to remedy immediately possible scrambling, for example reduction of control medium speed of feed or increase.
Yet these systems have some shortcomings.
At first, the printed article that copies on the move media (be used for limiting label, packing etc.) may with must obscure by the mark that optical sensor reads, therefore cause thus the mistake of identical optical sensor to read, and cause makeing mistakes in the determining of move media location.
In addition, for aesthetic reasons, preferably, above-mentioned being marked at stashes after final products are made.For example, the part of the show tags of cutting label (or the other unit element that begins to limit from move media) must be capped by the opposite end of overlapping label (in the situation of label winding related packaging), so as apply invisible afterwards on the packaging.Therefore, label must be longer than the length of actual needs, and this has caused larger material consumption and has increased production cost.If use the label of transparent or partially transparent, then mark can not be capped, thereby keeps as seen in final products.
Address the above problem at least part of, in the WO2011/012927 of same Applicant, advised using such supervisory system, this supervisory system imagination is not used mark or the symbol that is applied on the move media, the label that specifically applies for the container in labelling machine.
This system usually imagines identification and is imprinted in advance one or more reference areas in the label on the move media, described reference area is limited and calibrates the part of the identical printed article of signing pattern, and this system's imagination is used as " virtual tag (virtual mark) " with this reference area, to be used for identification label with respect to the position of the processing mechanism of medium.
Particularly, in the initial step of calibration, this system reads test label in the medium by optical sensor, and identification will be with one or more zones for referencial use in the printing material of this test label; This zone can be identified as the maximum zone of signal to noise ratio (S/N ratio) " SNR " easily, the measurement of comparison that perhaps begins to measure from the pixel value of the image that obtained by optical sensor.
In more detail, during calibration steps, the zone that test label is confined by optical sensor, and the starting point at this label, send test procedure commencing signal (this commencing signal is such as the forward position (leading edge) corresponding to digital signal, and this commencing signal is issued to optical sensor by the central control unit of labelling machine).And the test procedure end signal sends (this end signal also is issued to optical sensor by the central control unit of labelling machine, and for example corresponding to the negative edge (falling edge) of equalized digital signal) in the end of same test label.
The additional space coordinate of identifying in test label is clearly corresponding to the commencing signal in the test procedure and end signal; Interval between these volume coordinates thereby define the length of test label.
During whole duration of calibration steps, optical sensor obtains the one group signal relevant with test label.Given signal/noise ratio or given measurement of comparison and corresponding volume coordinate and each signal correction.When calibration steps finishes, the signal that obtains is processed, in order to be identified as zone corresponding to described one group of volume coordinate with reference to the district in test label, the maximal value of signal to noise ratio (S/N ratio) or measurement of comparison is relevant with described one group of volume coordinate.
Particularly, determine that thus the space of the reference area identify begins and end coordinate, and between the corresponding starting point of the starting point of test label or terminal and reference area or end definite off-set value.
Therefore this calibration steps allows supervisory system to limit a virtual tag at label, the easily identification of described virtual tag, do not need as providing in the system of traditional type, to print extra dedicated reference mark, thereby do not had this reference marker to produce all advantages.
Subsequently, during the operability treatment step of reality, supervisory system provides repeatedly: the label on the monitoring move media; Each identification is as having maximum signal to noise ratio or contrast and having treatment region for the zone of the given similarity of the reference area of test label or the degree of correlation in test label; The physical length of label is defined as starting point/end at the treatment region that current label detects with respect to the direct distance between the starting point/end in the respective handling district of the label before the move media; Control the processing operation according to the length value of determining for test label (owing to possible stretching, shortening or other scramblings in the operation, length value may be different from reference value).
For example, this last control step it is contemplated that examination length computation value with respect to the variation of the reference length of test label, and changes thus the move media speed of feed, in order to consider possible stretching or shortening.In addition, can determine to be applied to according to the variation of length value the proper proportion factor of the off-set value determined in the calibration steps, in order to correctly determine the starting point/end of test label from the starting point of the treatment region of identification/end spaces coordinate.
Therefore above-mentioned supervising device has obvious advantage for traditional system, and described supervisory system does not need extra mark or symbol are applied on the printed label on the move media particularly.Yet, even this system neither be fully immaculate.
Particularly, as mentioned above, calibration steps requires the reference area in the Recognition test label, and this shows at the central control unit of labelling machine and is exclusively used in the exchange of carrying out control signal between the optical sensor of this same calibration step.Therefore, the enforcement of this supervisory system necessarily requires to revise software and/or the hardware configuration of the same central control module of labelling machine, and this is to cause in some cases the operation that is difficult to implement.Further, during the calibration steps and between the actual treatment step, operating personnel may be difficult to or can not check immediately the proper operation of supervisory system, specifically aspect the reference area in the various labels of correct identification move media.
