Roll-2-Roll Technologies adds width measurement to its ARIS line of products. Absolute or relative web width can be measured based on the sensor configuration. With two output options the user has the flexibility to monitor the width based on their need. The real-time measurement can be output as an analog voltage between 0 to 10 Volts.

As the width changes the analog output increases or decreases proportionally. In this video absolute web width is measured using ARIS WPS 221 a 221 mm wide sensor. A 7 volt output corresponds to 70% width coverage which is equal to approximately 6 inches. The analog width measurement option can be used for quality monitoring and real-time control of web width in extrusion processes.

For low modulus webs, the width measurement can also be used to monitor necking in the web. The digital output option allows the user to set pass/fail conditions based on web width. A low and a high limit for width tolerance can be set. The resolution of the tolerance is in millimeters.

If the actual measurement is within the negative and positive width tolerance the voltage will be zero; this corresponds to a pass condition. If the width goes below the lower limit the output will be a negative voltage. A non-zero voltage is a fail condition. Similarly if the with goes above the upper limit the output is a positive voltage.

This pass/fail condition can be used for a variety of quality control purposes. For wider webs two sensors can be used for relative width monitoring. In that case the analog output corresponds to the percentage of web covering the two sensors. The absolute width of the web can be obtained based on the physical distance between the two sensors.

Our web guiding system, ARIS, features the latest in web guiding technology. It adapts to any material, requires no calibration, and is very simple to set-up. Our technology allows the sensor to be material agnostic, which means ARIS accurately detects the web edge position of any materials used without the need for manual adjustments. ARIS’ sensor technology works differently than any other currently available sensor in the market.

It uses the reflection of infrared light to take a picture of the edge of the material. This picture is then processed using digital signal processing algorithms to accurately sense the true position of the material irrespective of its physical properties. Other sensors use a blocking technique where the web is used to block light, sound or air. Since the amount of blocking depends on the material properties, the current sensor technology is less accurate with porous or transparent material.

Ultimately the web guiding performance is affected by the inaccurate sensor measurement. In this experiment, we will show you four materials, black nonwoven material, white nonwoven material, transparent film, and burlap. Our experimental setup is equipped with a high precision motor stage which moves the web material, which is 10 mm away from the sensor, back and forth. This setup is used to quantify the sensor performance.

With each material we repeat the exercise four times. The green line represents linear regression, which quantifies the precision and accuracy of the sensor. The blue represents the actual position of the web as measured by the sensor. Follow the results as the experiment progresses.

The video shows the web as it moves away from the center and the sensor’s ability to follow the position. The experiential results clearly show that the precision and accuracy of the sensor is unaffected by the material properties. Our sensor has linearity of plus or minus 1 percent without any calibration. Find out more information about ARIS and our sensors, using the link in our description below.

our web guidance system RS features the latest in web garden technology in adapts to any material requires no calibration and it is very simple to setup our technology allows the sensor to be material agnostic this means ours accurately detects the web edge position of any materials used without the need for manual adjustments our SS sensor technology works differently than any other currently available sensor in the market it uses the reflection of infrared light to take a picture of the edge of the material this pictures and processed using digital signal processing algorithms to accurately sense the true position of the material irrespective of its physical properties other sensors use a blocking technique where the web is used the block light sounder air since the amount of blocking depends on the material properties the current sensing technology is less accurate with porous or transparent materials ultimately the web Guardian performance is affected by the inaccurate sensor measurement in addition to sensing capabilities ours communicates intelligently with the sensor watch the screen as we show how the sensor communicates with ours a green web detected indicator will verify that the edge is detected by the sensor if the sensor is not connected properly or if the edges outside the window the indicator will not really about the icons you will see a material edge position indicator when the material is in the correct position you will see one red bar and one green bar the green bar indicates the metal portion of the sensor and ideally the web should be in the green bar region if it's incorrectly positioned you will either see no green bar or you will see red bars on both sides of the green if the sensor is not within the measurable distance then the material edge position indicator will be grave the sensor position indicator on either side of the web guide picture shows the position of the sensor with respect to the guide if the sensor indicator does not register the sensor on a correct side of the web or the green bars is white on the wrong side of the web press the find sensor to automatically register at the sensor position indicator to make it simple and foolproof the intelligence and ours can work irrespective of the sensor position as long as the web is inside the sensing window if no sensor is connected or if the sensor is faulty none of the position indicators will be lit when the sensor has plugged back in ours will automatically register the correct sensor position find out more about Aras and our sensors using the link in our description below

The video shows ARIS guiding a burlap web at different frequencies and a web speed of 4.26 meter per second. Using a two guide test machine, we will show you several speeds and several disturbance frequencies that are introduced to evaluate the performance of ARIS when it handles burlap, a non-porous material. Watch the red laser to see difference of the controller when its on vs when its off. As a porous material, burlap presents a special challenge because current sensing technology is not able to handle the gaps between the threads of the material.

The image processing in the sensing technology in ARIS allows it to detect the edges of a porous material. You can find a link for more information in our description below

ARIS is an intelligent guiding system that uses a revolutionary fiber optic sensing technology to accurately measure web position. In this video, we use a two guide test machine to introduce several speeds and disturbance frequencies. One machine creates the disturbance, while one corrects this disturbance This test lets us evaluate how our machine adjusts to these disturbances. Watch the red laser to difference between when the controller is off vs when it’s on.

We have a white paper on our website that gives more information about the performance of our guide systems. For more information, please click on the link below in our description.

As a real plug-and-play system, ARIS adapts to any material, requires no calibration, and very little set-up time. First plug in the sensor to the 12 prong outlet in the back of the machine, using the guide notch that aligns the plug to the outlet. Once the sensor is plugged in, tighten the lock collar to hold the sensor cord in place. Slide the sensor into the sensor guide rail.

Make sure the middle of the sensor is aligned with the material’s edge. Once connected to a 24 volt power supply, the user operator interface featuring language independent icons will come. A green sensor indicator will verify an operable sensor. Above the icons you will see the material edge, position indicator, represented by a green and red bars.

When the material is in correct position, you will see one red bar and one green bar. If it's incorrectly placed, you will either see no green bar or red bars on both sides of the green. Once the sensor has been aligned with web, secure the sensor using the thumb screws. When the screen turns on, the automatic/manual icon will indicating the guides last operating condition.

A green icon indicates the guide is in automatic operation. A red icon indicates the guide is in manual operation. The operator can change the condition by pressing the icon once. ARIS does most of the work through its automatic option, so press the icon to set to green and let it roll.

Hello, this is Pedro with Roll-2-Roll technologies and we're going to talk to you a little bit of our sensors especially the array on sensors that we have available to the market now we have talked before about the WPS 48 which is a 48-millimeter sensing window and the 221 with a wider window available for a mostly center guiding and it can do edge detection as the other can and also it does you know thread counting and it can be used to monitor web width as one of the many features it has. however we're introducing to the market something we just developed in which will be available in May to the industry which is the WPS 440 IR. It includes also the same infrared signal and it has a four hundred forty millimeter sensing window but one of the best features of it all is it even though these require a sensor control unit this has a central control unit enclosed within the same package. All you have to do is connect two cables and the sensor is ready to go.

Now with this you can monitor remotely a web but the same time you can also control a web guiding system. So this is available to the market in May, we're going to be showcasing this at ICE USA 2017. We'll be at Booth 1034 and we can actually see the sensor in operation over there. So in order to get some more information about our products, visit our website the www.r2r-tech.com and see some more about our products thank you

Today we want to show you another of the features of our sensors In this case, we have a 221 mm sensor, we can use for center guiding and at the same time for edge guiding, you just by flipping on off switch. Right now We have it set on a 15 inch guide. And it right now set up and run, as a center guide. However so what I'm going to do now we don't recommend you do it on your machine but just to show you how easy it is to just switch the one from center guiding to edge guiding.

So right now as you can see its set on center guiding. Now, I'm going to put the web guide out of automatic to manual and then I'm going to slide the sensor all the way for the position where it's going to be edge guiding on the same position that we have it right and then I'm going to turn it back on and and do edge and find sensor, and I'm going to turn it back on. You can see the maintain same position It's doing exactly edge guiding in the same position.
