Abstract
The present invention relates to a kind of LED UV driers for UV light curable ink：LED is set in the housing, and the housing has transparency cover in LED light path, wherein, the temperature difference in the temperature of lid or the position spaced apart of lid is detected, and therefrom to derive, show dustiness, and turns off LED UV driers in a further step.
Description
Technical field
The present invention relates to a kind of device for being used to monitor LED-UV- dryer temperatures.
Background technology
LED-UV- driers are used for UV curing-ink or gloss varnish, such as monochromatic or colored ground is carried out on ink-jet printer
Printing or mark page, the three-dimensional structure made of metal or plastics, or also carry out in rotary press.
The LED for being used for UV curing light curable ink for example in printing machine is disclosed by the A1 of DE 102009007873
Drier.Here, multiple LED are disposed transverse to the conveying direction of stock on bearing part in the form of tandem.
Disclosed by the A2 of WO 2011/031529, LED is set in the housing to prevent from polluting and damage, that is, is set
LED-UV- patterns, and the housing is provided with transparent lid in the region that UV ray is radiated.
Occurs the problem of so in practice：Transparency cover is contaminated for example, by dust, steam or mist of oil.These are dirty
Dye result in the absorption to UV light, and therefore cause transparency cover uneven heating.Thus, the weakening of radiation intensity is on the one hand formed
And on the other hand transparency cover is caused to be damaged due to the caused stress cracking of uneven heating.
The content of the invention
Therefore, task of the invention is, a kind of method and a kind of device is proposed, by means of methods described and described device
The pollution for the dustiness for reaching predetermined can be identified.
According to the present invention, the task solves by the feature of the present invention.
Particular advantage of the present invention is：Can be in the hope of the heating of transparency cover in LED radioactive area.Because while UV-
Just " cold ", but the pollution on transparency cover result in UV- light and be absorbed and therefore cause temperature rise, particularly result in
Temperature difference between lid diverse location., on the other hand can be with by obtaining or on the one hand detection temperature can determine dustiness
Avoid causing to cover the fracture of (such as glass plate) due to temperature difference.
In order to which temperature is poor, at least two each other away from setting temperature sensor detection lid temperature and by these
Information is transferred to analysis and processing unit again, and the analysis and processing unit relatively provides afterwards in progress rated value with actual value to be used for
Cleaning covers corresponding signal and the signal for closing LED is provided in the second level.
Temperature sensor, which can be arranged directly on, to be covered, or the space with being arranged on being stamped spacing between LED and lid
In, so as to non-cpntact measurement.
Brief description of the drawings
Two embodiments of the present invention are shown in the drawings and are described below.
Wherein：
Fig. 1：Diagrammatically illustrate the section of page rotary press；
Fig. 2：Diagrammatically illustrate the section of LED-UV- driers；
Fig. 3：Diagrammatically illustrate other LED-UV- driers；
Fig. 4：Show the top view arranged according to the LED strip of Fig. 3 LED-UV- driers.
Embodiment

These printing mechanisms include a plate cylinder 11,12 respectively in known manner.These plate cylinders 11 and 12 have respectively
One device for being used for fixing flexible printing forme.In addition, to each plate cylinder 11,12 be equipped with one be used for it is semi-automatic or it is complete from
The device of dynamic ground changing of printing plates.
Page stack 8 be placed in can the master of controlled lifting stack on plate 10.Page 7 is realized by means of so-called dust collecter 13
Stack from page and taken out above 8, the dust collecter has multiple liftings-and traction for page 7 to be divided into individual in addition
Aspirator.In addition it is provided with and is used to make the loose blowing device of the top page layer of beat element to carry out stacking tracking.For
Make page stack 8, particularly page and stack the pages 7 of 8 tops to orient, there is provided multiple lateral and rear backstops.
Be provided that when being printed using UV cured printing inks, by printing-ink be delivered to for example page, paper tinsel,
Transmission position rear on the stock of metal, plastics etc. is provided with LED-UV- driers 14, wherein, the stock can page
The form of opening can also construct to 3D forms, and the LED-UV- driers promote to solidify by radiating new printing image
Ink.It is apparent that printing image can also be generated by ink-jet printer.
In the embodiment in accordance with fig. 1, page rotary press 1 has multiple LED-UV- driers 14, these LED-
UV- driers are with relative to predetermined printing cylinder 16,17 less spacing settings and/or for the defeated of page to be placed
In the region for sending the collector 6 above path.
LED-UV- driers 14 have housing 18, and the housing is set transverse to page conveying direction.Housing 18 includes cold
But unit 19, LED 21 that tandem is set, sending UV light is provided with the cooling unit.It is provided with LED 21 light path
First optics 22 and the second optics 23 with interval.The housing is on the beam exit surface projected from housing 18
Closed by means of transparency cover 24.
The temperature sensor 26,27 contacted with transparency cover 24 is provided with two spaced positions.Temperature sensor
26th, 27 are connected with analysis and processing unit 28.
The analysis and processing unit utilizes obtained temperature value or the temperature difference obtained to perform rated value and reality
The comparison of actual value；In the first stage, the signal for clean transparent lid 24 is provided in the case of beyond given tolerance value；
In the second level, provided in the case of beyond given, higher deviation for turn off LED21 signal, for example pass through shut-off
Current/voltage supplies.
Temperature sensor 31 to 33 is provided with the second embodiment according to Fig. 3, these temperature sensors are arranged on LED
The non-contactly measurement temperature between tandem 21 and in housing 18.Different temperatures based on non-cpntact measurement can be inferred that
The pollution of bright lid 24.Equally realized and analyzed and processed by means of analysis and processing unit 28.
