  Inline spray jet control outside and inside the potentially explosive atmosphere!

Surface coatings are often applied by spraying. Ideally, objects should be coated homogeneously. Air pockets in the spraying medium, partial covering of the nozzle outlet apertures or an abrupt pressure fall in the spraying system can result in inhomogeneities in the spray cover and thus uneven coating of the workpiece. Timely recognition of deviation from the ideal spraying procedure can be performed via continual spray jet control. The spray jet control systems of the SI-JET series and the SPECTRO series from Sensor Instruments GmbH provide information about the spraying quantity, the length of interruptions and the spray jet symmetry.
Three-jet systems (SI-JET-CONLAS3 and SI-JET3) two-jet systems (SPECTRO-2) one-jet systems (SPECTRO-1) and continuous light barriers (L-LAS-TB-…-SC) are available to perform the respective task.

  Inline gloss measurement of painted wooden panels.

The human eye reacts principally to differences in contrast (differences in gloss) and color. For example, if we look at freshly-installed floor boards, we immediately notice even the smallest differences in color and gloss between the individual panels. It comes therefore as no surprise that manufacturers do their very best to minimize difference in color and gloss between the individual panels. The checking process conducted to this end was previously performed using hand-held offline measuring units; Sensor Instruments GmbH has developed an inline alternative.
Our GLOSS series gloss detection sensors can measure the gloss grade of painted wooden panels in the angles 20°, 60° and 85° at a distance of 20mm, 15mm and 5mm to the surface (depending on the sensor type: GLOSS-20-20°, GLOSS-15-60°, GLOSS-5-85°).

  The color tone is decisive: the color tone measurement of various colored fiber bundles.

The color tone of textile fibers should, as far as possible, be measured at the start of the textile dyeing process using inline measurement. The information about the actual color tone (the actual value) can be compared with the color tone target using the PLC. The difference between these two color values provides information as to whether a more or less color should be added to the color bath.
A SPECTRO-3-28-45°/0°-MSM-ANA-DL is suitable for measuring the color of the fiber strand which is fitted with a 45° illumination and detects the color under 0°. It is thus possible to avoid the great majority of direct reflection as comes from dye which is still damp during measurement. The distance between the sensor and the color strand is typically 28 mm and the detection range assumes a diameter of c. 10 mm with this clearance.

  Color differentiation of second hand clothes in the recycling process.

Different colored second hand clothes, transported on a conveyor belt, should be differentiated. At this, the orientation of the respective textile is randomly, which means randomly folded, flat or exaggerated positioned. Furthermore, the clothes will be transported serial on the conveyor belt, normally with a certain gap between the respective textiles, thus, the surface of the conveyor belt can be seen from the top side. Additionally, the speed of the conveyor belt is constant and approximately 1m/s. Once the color is detected, a special high-pressure nozzle is blowing the respective clothing item out from the conveyor belt and into a foreseen container.
For the preliminary studies a color measurement sensor type SPECTRO-3-1000-COF-d50.0-CL-MSM-DIG is used.

  Micrometer-exact positioning of punching strips.

During the production of punched articles, the punching procedure requires the exact positioning of the punching strips as the processing of the punching strip is performed in a number of process steps in the punching machine. The metal band must be positioned exactly within the punching tool after every processing step (punching and bending procedure). The position notification is usually performed within a stroke procedure (0°…180°) using a through beam light barrier and assignment of the respective rotary encoder position during the signal exchange of the light barrier. Ideally, the through beam light barrier should be a fork light barrier and should be able to be integrated in the punching tool, something which requires robust sensors which can resist mechanical vibration. The light barrier should be cutting oil resistant and insensitive to soiling. Quick running punching machines under the presses running at several thousand strokes per minute require a very high switching frequency and a high degree of position-exactness.
The fork light barriers of the FIA-L series from Sensor Instruments GmbH were designed especially for this deployment. In addition to a high degree of insensitivity to extraneous light, a high level of oil resistance, a small laser spot size of 0.2mm in diameter, a low optical divergence of the red laser beam and a high position exactness of better than 5µm, the FIA-L-RL series provides a switching frequency of 25kHz.

  Differentiating the tin side from the fire side in float glasses.

Float glasses develop their form, thickness and surface properties through the transport of the glass melt on liquid tin. The glass melt floats on the tin bath and develops a plane surface adapted to the tin bath (tin side). The glass surface facing away from the tin bath (fire side) is heated by a gas burner until a certain temperature profile develops so that the glass melt can cool gradually and thereby assume its later form.
When processing the float glass further, it is important to know where the tin side is located and where the fire side is located. Tin microinclusions can influence a number of issues such as the electrical resistance of the glass surface (the application of metal contact strips on a car rear window). It is also of decisive importance in other matters such as the application of further layers on the glass surface (e.g. nano layers) as to which side of the float glass is coated.
The SPECTRO-1-20-UVC-DIL UVC contrast sensor from Sensor Instruments GmbH permits control of the glass surface in terms of its tin or fire side.

  The detection of oil layers on metal surfaces: comparing the measurement procedures.

The use of oils is imperative in the forming process of metals. For example, the application of cutting oils to metal bands ensures low wear on the punching tools. Drilling oils make an essential contribution to the protection of the drilling and milling tools during chipping processes. Oils also serve to protect semi-products such as sheets and metal foils against corrosion. After further processing, it is important to remove the oil residues from the finished products as completely as possible. This task is performed by special cleaning systems, in which the metal parts are washed and blown dry.
In order to ensure that environmental specifications are maintained during the application of the oils, and to ensure that the process is economical, it is advisable to ascertain the quantity of the oil applied. Oil quantity measurement can be performed INLINE. A number of measurement procedures are available to this end and which constitute the focus here. The cleaning process can be monitored using the same sensors. The challenge is to determine even small quantities of oil residue accurately, preferably INLINE. Electrically conducting components such as copper busbars or power current lines require the lowest possible transfer resistance. A residual oil layer would pose a problem as this restricts the conductive efficiency to a considerable degree.

  What is going on in the haze? We watch the oil even during evaporation!

Producers of blanked and flexible parts are increasingly using evaporated punching and drawing oils. Such processes need an outcome which minimizes the oil residue on the punched or formed metal parts in order to obviate the need to subject the products to a cleaning process. The question is: how much of the oil remains on the component and how long does the evaporation process take?
Our SPECTRO-M series answers this question! To this end, we applied five drops of oil (5x20µl) to a degreased steel plate and spread it over a 70mm diameter surface. The oil layer thickness at the start of the measuring procedure amounted to some 25µm. The SPECTRO-M-10-MIR/(MIR1+MIR2) sensor was then placed on the center of the oil and the measurement started: The MIR sensor was used to view two measuring windows, both of which were located in the mid-wavelength infrared light range (MIR range). One of these two wavelength range windows reacts to the presence of oil (here referred to as CH0), whilst the second measuring window (CH1) gave no reaction. This change in the two measuring windows upon the presence of oil can be used to ascertain the amount of oil within the detection range.

  Measuring the thickness of oil layers by comparing two mid-wavelength infrared light range wavelength windows.

Those wishing to measure the layer thickness e.g. of a homogeneous layer of printing ink on paper can adopt the grammage method as an adequate approach. The grammage of a printing ink is not all that different from that of paper with a thickness of between 0.05 mm and 0.2 mm. The use of accurate scales should be able to produce a reliable result. What happens when we replace printing ink with oil and paper with a 1 mm steel sheet? We would probably come to the limits of the grammage method.
We still need a reliable method of determining the thicknesses of oil layers without too much effort. One possible solution is the fluorescence method, using UVA light to stimulate fluorescence. Secondary emissions are emitted in the visible wavelength range. The intensity of the fluorescence establishes the measure for the thickness of the respective oil layer. We should take into consideration however, that the signal strength (fluorescence) is not only dependent on the layer thickness but also the nature of the oil used and the metal surface which functions as a reflector and exerts an influence on the signal level. There are also a number of oils with only a minimal or no fluorescence effect and which cannot be measured to establish the layer thickness.
Taking the mid-wavelength infrared light range (MIR) into consideration, we see that the oils previously investigated all exhibit a significant absorption in a certain wavelength range, whilst other wavelength ranges do not respond to the presence of oil. Were we to exclude this oil-sensitive wavelength window from the MIR spectrum and then compare its absorption behavior in standardized fashion with the absorption observed in a second, oil-neural wavelength window, we have a first approximation of a proportional relationship between the thickness of the oil layer and the standardized signal.
The SPECTRO-M-10-MIR/(MIR1+MIR2) sensor if fitted with exactly this wavelength window.

  The measurement of thin oil layers with MIR – a highly interesting matter.

The tension is rising! The users of cleaning units for metal parts – e.g. stamped parts – wait with baited breath to see what the washing sequence brings forth. Has the surface tension exceeded the threshold of 38 mN/m or has it even climbed to 44 mN/m? A metal component is generally taken to have been de-greased if one of these values (which of the two, depends on the intended application) has been exceeded. Previously, test ink was used to demonstrate the surface tension. These liquids are available in various surface tension values, usually starting with 30mN/m to 50mN/m in steps of 2mN/m (30mN/m, 32mN/m, …, 48mN/m, 50mN/m). If the test ink does not roll off the metal surface after application, the surface tension of the metal part lies above the value specified for the test ink. On the other hand, if the test ink does roll off the metal surface, the surface tension of the metal lies below the value specified for the test ink. In this way, the surface tension can be ascertained with an accuracy of 2mN/m.
What does the surface tension mean in relation to the property of the respective metal surface? De-greased metal surfaces present a surface tension above 50mN/m (ascertained with the test ink method). On the other hand, if a metal surface is covered with an oil film, (for example, through oiling the punching strip before punching), the value of the surface tension can fall under 30mN/m, depending on the thickness of the film. The test ink method is therefore capable of determining whether the metal surface is covered with an oil film, or whether it has been removed (de-greased). Even oil films of less than 1µm can be demonstrated with this method.
Experiments with various oils have shown that almost all oils have a selective absorption rate in the mid-wavelength infrared light range (MIR). Using this characteristic means that the comparison of two MIR wavelength ranges (one range is the neutral range, i.e. the wavelength range in which no noticeable absorption occurs as a result of the oil) can be used to determine the thickness of the oil layer after calibration of the SPECTRO-M-10-MIR/(MIR1+MIR2) measurement system, and in a subsequent step, to display the respective surface tension value.

  Sustainable v. virgin!

The arrival of plastic recyclates.

A difficult birth! After standing in the shadow of virgin materials for many years, plastic recyclates have now come into their own. There are many reasons for this: whilst the complex technical procedures to which recycled plastic must be subjected rendered them uneconomic, technological improvements mean that the quality could be improved whilst reducing costs. Despite these advances, without the decision on the part of the EU to change the legal framework to effect the sustainable use of plastics, recyclates would have remained uneconomic. For example, an EU directive has established a minimum amount of plastic recyclates to be used in plastic bottles.
Despite their improved properties, plastic recyclates still do not approach the quality of virgin material. For example, color deviations in comparison to the target state are still common. Color value targets can only be reached by the targeted addition of virgin material. Determining the exact quantity of new material to be added requires color measurement of the plastic recyclate.
Color measurement is performed INLINE. The high ambient temperature means that color measurement system is realized as a fiber optic system (KL-D-0°/45°-85-1200-A3.0-VIS) and works in accordance with the 0°/45° color measurement procedure. When using a white light spot diameter of 25 mm, an average is ascertained optically over a large number of pellets, so that the evaluation unit connected to the fiber optic front end SPECTRO-3-FIO-MSM-ANA-DLcan determine a precise color value (L*a*b* or xyY). The color values are transmitted to the control of the metering unit and depending on the color deviation from the target, the metering unit will add virgin material as required.

  Color Measurement of Painted Metal Plates

The color of metal plates should be measured immediately after the painting process. It must be taken into account here that there are both high-gloss surfaces and very dull surfaces, and that the color value must be determined irrespective of the gloss factor. Furthermore, measurement must be performed inline, on the one hand to satisfy the requirements of 100% inspection, and on the other hand to be able to quickly respond to a possible color drift.
The recommended color sensor for this application is a sensor of the SPECTRO-3 series operating with the 45°/0° method (SPECTRO-3-28-45°/0°-MSM-ANA-DL).

  No Problems Counting Fan Blades

In the production of radial and axial fans the checking of the correct frequency response depending on the applied DC voltage is one of the final steps. The easiest method for measuring the frequency is to use a transmitted-light sensor (for example a D-LAS2-d1.0-T + D-LAS2-Q-d1.0-R-HS, featuring a switching frequency of typ. 300kHz). In many cases, however, the fan blades of the respective fan version only can be accessed from one side for testing, so that a reflected-light sensor must be used as an alternative.
The edge detectors of the RED series (RED-50-L or RED-110-L) are excellently suited for such applications.

In this application an edge detector of the RED series (e.g. RED-50-L or RED-110-L) is used to count the folds. During edge counting the aluminium flex-pipe is moved along the laser sensor. The sensor provides a digital output signal for every edge.

  Frequency of Compressor Wheels

The task is to measure the frequency of compressor wheels that are used in turbochargers. These wheels may reach speeds of up to 300,000 revolutions per minute. Usually these compressor wheels have about 10 blades and are made of milled aluminum. If the frequency of these compressor wheels should be determined optically it must be taken into consideration that every blade causes a signal change - which means that up to 3,000,000 switching processes must be expected per minute, resulting in a frequency of approx. 50 kHz (of the blades). Even an edge detector of type RED-50-P or RED-110-P with its maximum scan frequency of typ. 100 kHz will work up quite a "sweat" here.

  Do not overstep the red line

Plastic wires with various thicknesses, colors, forms and surface properties are used for a range of different purposes. Examples include tennis rackets with polyester monofilaments; the triangular profile of the racket strings produces greater spin. Flat material is most suitable for the monofilaments used in the production of large plastic bags (big bags). Transport filter belts used in the wet areas of paper production are made of round plastic monofilaments; the plastic wires used in toothbrushes have abrasive material added to them. Plastic monofilaments are now also used in 3-D printing procedures. This process also uses round wires with various diameters. In addition to the form, color consistency is decisive, as color deviations in plastics are often interpreted as quality inconsistencies. Woven products such as plastic sieves, big bags and tennis rackets are especially prone to this phenomenon as even very small color nuances (usually from a color difference of dE=1) are perceptible. Manufacturers need to inspect the color of the monofilaments during production, i.e. inline. The object size, form and gloss of the plastic monofilaments have previously impeded the use of inline color measuring devices, especially as a color deviation of > dE = 0.7 needs to be detected reliably.

Through semi-transparent flat strips these light guide rods guide the light into the interior of the car. Any inhomogeneity in the light guide rod would influence the scattering behaviour of the output light. When driving in the dark, a passenger in the car interior would notice this as a bright or dark position along the light strip and would be disturbed by it.

Inline Detectors Offer a new Method of Component Marking
In the course of a comprehensive digitisation of industrial production and processes (keyword: Industry 4.0) a new method of marking manufactured components now offers previously undreamed-of possibilities. By way of an individual marking (a random distribution of fluorescent particles on the object surface or in the object matrix) a virtual key can be generated and can be used to save product-relevant data e.g. on the server (or in the cloud). Due to the random distribution of these fluorescent particles this "star code" represents a kind of "digital fingerprint". Already a few particles in the viewing field are sufficient to guarantee safe and robust recognition, with little required memory space per code.

  Choose the Right Side

95% of all the industrially produced flat glass today is made using the float glass process. In this process, molten glass is continuously fed into a bath of molten tin. Due to its lower specific weight the molten glass floats on the smooth tin surface, and on a long tin bath forms a uniformly thick and extremely smooth film. The glass side that faces the molten tin is slightly contaminated with tin, which has corresponding effects on subsequent float glass processing steps such as coating of the glass surface.
For the further processing of float glass it is therefore important that the surface that is contaminated by the tin bath can be distinguished from the so-called fire side (fire polishing, during float glass production the glass side facing away from the molten tin is heated).

그러나 가까운 미래에 센서와 프로그래머블 로직 컨트롤러 (PLC) 간의 통신은 그에 상응하여 높은 데이터 전송률을 갖는 디지털 직렬 형태로 수행 될 것입니다. 미래는 소위 말해서 산업용

  Detection of Transparent Edges

종래의 검출기는 플라스틱 캡의 플라스틱 마시는 컵과 같은 누적 된 투명 물체를 감지하고 계수해야 할 때 특히 한계에 도달합니다.
그러나 포장 공정에서 특히, 포장 단위에 정확한 수의 물체를 배치하는 것이 매우 중요 합니다.이러한 문제는 이제 RED 시리즈 해결할 수 있습니다 (이 응용 프로그램에는 RED-110-L이용 될수가 있습니다).

  A Hazy Problem?

처음에는 모든 것이 명확 해 보였습니다. GLOSS 시리즈 센서 중 하나를 사용하여 문제없이 관리 할 수 있는 또 다른 측정 작업이었습니다.

고객이 제공 한 설명에 따르면 광택 등급 측정 작업 인 것처럼 보였고 처음에는 수직 측정에서 20 °, 60 ° 또는 85 ° 각도 측정을 수행해야 하는 유일한 질문이 될 것 같이 보였습니까?

  Perfect Copy Counting

판지, 잡지 또는 낱장이 포장 된 경우, 각 포장에 정확한 개수의 품목이 들어 있는지 확인해야합니다.대부분의 경우 이러한 물질은 잡지, 신문 또는 광고 인쇄물과 같이 보상 스태커를 사용하여 포장하기 전에 섞인 형태로 운송됩니다. 개별 복사물의 두께와 이송 속도 (최대 10m / s)에 따라 the shingled stream은 이 공정에서 서로 다른 높이를 가질 수 있습니다.

  Clear Strategy or Plain Guessing?

지난 몇 년 동안 windscreen의 스프레이 노즐은 상당히 발전 했다.이제 제트기는 Fan-jet제트 또는 spot jet 로 제공됩니다. 의도 된 각도 범위에서 균일 한 spray mist 적용이 fan-jet 정확하게 보장되며, 정확히 지향되고 거의 발산하지 않는 spot-jet를 통해 전면 카메라에서 point-shape(점 형태) 제트가 적용됩니다.

  INLINE Color Measurement of Paint
Through a 15mm Thick Inspection Glass

일반적으로 생산 중 컬러 페인트의 색상 검사는 주로 실험실에서 끝나게 됩니다.페인트 샘플을 채취 하고 이 샘플의 색상을 건조한 상태의 얇은 페인트 층을 통해 확인합니다.

이 과정은 물론 페인트 생산이 허용 공차를 벗어날 수있는 시간이 걸리므로 시간이 오래 걸리고 고비용의 후속 처리가 필요합니다.

  Accurate High-Speed Counting of Stacked Plastic Caps

특히 투명하고 적층 된 플라스틱 뚜껑의 계산,예를 들어 빈번하게 포장 산업에서 사용되기 때문에,대개 매우 문제가 되는 응용 프로그램입니다.왜냐하면 한편으로는 개별 캡의 가장자리가 항상 정확하게 정렬되는 것은 아니며 반대로 반사광 원리로 작동하는 복사 카운터는 특히 투명한 물체와 함께 신뢰할 수 있는 계산 결과를 제공하지 않기 때문 입니다.
