Description
Vynález rieši bezkontaktně snímanie priemeru svitku pri navíjení alebo rozvíjení pásu.The invention solves non-contact scanning of the diameter of the coil when winding or unwinding the strip.
V súčasnej době sa na snímanie priemeru navíjaných alebo rozvíjených svitkov pásu používá jú jednak snímače, ktoré pracujú na principe priameho mechanického kopírovania priemeru kladičkou spriahnutou s vonkajším priemerom svitku alebo snímače, ktoré pracujú na principe neprlameho merania priemeru podlh obvodovej rýchlosti. Nevýhodou mechanického kopírovania je možnost· poškodenia upraveného povrchu pásu kladičkou, sthžený přístup, ako i robustnost’ a zložitost’ zariadenia. Nevýhoda druhého sposobu spočívá v příliš vel*kých nákladoch na zaistenie merania a v zložitosti regulačného zariadenia.At present, sensors for working on the principle of direct mechanical copying of the diameter by a roller coupled to the outer diameter of the coil or sensors working on the principle of indirect measurement of the diameter of the peripheral speed floors are used for sensing the diameter of the coiled or developed belt coils. The disadvantages of mechanical copying are the possibility of damaging the treated belt surface with a pulley, a tightened approach, as well as the robustness and complexity of the device. The disadvantage of the second method lies in the too high cost of ensuring the measurement and the complexity of the control device.
Uvedené nevýhody odstraňuje zariadenie na snímanie priemeru navíjeného alebo rozvíjeného svitku pásu, ktorého podstata spočívá v tom, že nad povrohom svitku rovnoběžně a jeho osou sú oproti sebe umiestnené v spoločnom držiaku světelný zdroj a nastavitelné čidlo.The above-mentioned disadvantages are eliminated by the device for sensing the diameter of the coiled or developed strip coil, which is based on the fact that a light source and an adjustable sensor are arranged opposite each other in the common holder in parallel to the axis of the coil.
Výhodou zariadenia je univerzálnost’ jeho použitia pre široký rozsah priemerov svitkov, ako i velká přesnost’snímaných hodnot. Vzhlfedom k tomu, že sa jedná o bezkontaktný sposob snímania, vylučuje sa úplné nebezpečenstvo mechanického poškodenia upraveného povrchu pásu. V neposlednom radě je výhodou zariadenia jeho jednoduchá konštrukcia a l’ahká namontovat eUnos V na příslušné navíjaoie alebo rozvíjacie zariadenie.The advantage of the device is its versatility for a wide range of coil diameters as well as the high accuracy of its sensed values. Since this is a non-contact scanning method, there is no risk of mechanical damage to the treated belt surface. Last but not least, the advantage of the device is its simple construction and easy mounting of the eUnos V to the respective winding or developing device.

Zariadenie na bezkontaktně snímanie priemeru navíjaného alebo rozvíjeného svitku pásu pozostáva zo společného držiaka 2» v ktorom sú oproti sebe uložené světelný zdroj 2. a nastavitelné světelné čidlo 2 tak, aby boli umiestnené jednak nad povrchem svitku £ upevněného v upínacom trne £ navíjačky alebo rozvíjačky, a jednak aby boli umiestnené rovnoběžně s osou svitku £. Spoločný držiak 2 3® upevněný na telese převodovky 6 spojenej s hnacím motorom 2· Optika, ktorou je světelný zdroj 2 vybavený umožňuje usměrnit* světelný lúč tak, aby dopadal pod určitým uhlom na povrch navíjaného alebo rozvíjeného svitku £. Konštrukoia nastavitelného světelného čidla 2 dovol*uje jeho natáčanie v kolmej rovině v závislosti od priemeru svitku £, ako aj změnu polohy jeho indukujúoej vrstvy. Počas prevádzky světelný zdroj 2 vysiela usměrněný světelný lúč, ktorý dopadá na lesklý povroh navíjaného alebo rozvíjeného svitku, od ktorého sa odráža, pričom odrazený lúč vniká do štrbiny světelného čidla 2« kde sa spracováva na elektrický signál. Bod odrazu světelného lúča sa mění s narastajúcim alebo zmenšujúcim sa priemerom svitku £. V závislosti od změny bodu odrazu mění sa i poloha odrazeného světelného lúča, ktorý vniká ces štrbinu do světelného čidla 2· kde ovplyvňuje jeho indikujúoi vrstvu, od ktoréj závisí hodnota elektrického signálu, ktorý slúži na korekoiu obvodovéj rýchlosti svitku £.The device for contactless sensing of the diameter of the coiled or unwound belt coil consists of a common holder 2 in which the light source 2 and the adjustable light sensor 2 are arranged opposite each other so that they are positioned above the surface of the coil 6 mounted in the mandrel 4 and on the other hand, to be positioned parallel to the axis of the roll. The common holder 23 mounted on the transmission housing 6 connected to the drive motor 2 The optics of the light source 2 make it possible to direct the light beam so that it falls at an angle to the surface of the coiled or unfolded coil 6. The design of the adjustable light sensor 2 allows it to be rotated in a perpendicular plane depending on the diameter of the coil 6 as well as to change the position of its inducing layer. During operation, the light source 2 emits a rectified light beam which impinges on the glossy surface of the coiled or unwound coil from which it is reflected, the reflected beam penetrating into the slit of the light sensor 2 ' where it is processed into an electrical signal. The point of reflection of the light beam changes with increasing or decreasing diameter of the coil 8. Depending on the change of reflection point, the position of the reflected light beam, which penetrates through the slit into the light sensor 2, also changes where it affects its indicating layer, on which the value of the electrical signal serves to correct the peripheral speed of the coil.
