Demos

this is February Lascaux of rolls roll technologies in our series of showing you about that some features of our webcast and today we want to show you how simple it is to install the cat just to put it in operation right now we're showing you a 12 inch web guide which if we have installed in our testbench and it's a really simple it's four points where we actually fix it to the Machine and what happened the same one you're in your facility now in this case we already thread the machine the web guide with some the two and we have position the sensor where we would like to show a habit position as you can see it's a very simple sensor so it only has one face and so it's a taken away from the u-shape remember our sensors can actually detect any kind of material without having to be adjusted and now as you can see on the back side of our guide you can see that there are only two positions that we're going to plug into the first one is we plug in the sensor we have actually identified the sensor position sensor 1 and then we connect our power supply just fix it to it and if we look at the other side that as you can see the web guide reacted because it's already in operation let's go to the other side to the front and you can see our panel right here see and now it's indicating that it has located the sensor and it's ready to go and now I'm going to put this machine to work as you can see this is a very simple installation what we did let's just plug into two cables and when the key is operational come with us to Roloff acknowledges and this melts you understand more or less and how I guess didn't plug in place

RS 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 show how RS handles change in materials one machine creates the disturbance while one corrects this disturbance air patented agnostic material sensor allows RS to adapt seamlessly to any material including paper transparent plastic non-woven and textile without having to manually readjust the machine watch the red laser to see the difference between the controller when it is on versus when it's off you can find a link to more information in our description below e

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.

In this video we show how quick and easy it is to install an ARIS Web Guiding System. Unpack the box and lay down all the components such as the cables, web guide mechanism, the web position sensor and power supply. The compact web guiding system is pre-wired for easy installation. All that is required is a single allen wrench tool to fasten the web guide to your machine frame using the mounting holes at the bottom of the web guide.

We even provide the 6 millimeter mounting screws with spacers to make it really quick and easy for you. Carefully unscrew the four mounting screws and spacers from the web guide. Place the four spacers over the pre-drilled mounting plate on your machine. Carefully set the web guide over the spacers paying attention to the direction of travel of the web.

Use an allen wrench to securely mount the web guide onto your machine frame. The compact and lightweight design of our web guiding system makes it easier for quick installation on your machine. The mounting holes also provide the necessary electrical grounding of the web guiding system if the machine frame is properly grounded. Please refer to our user manual for more information about grounding.

Next mount the web position sensor on the aluminum rails already mounted on the web guide. Use the thumbscrews to secure the sensor to a desired position. Using the 12 pin DIN connector on the sensor cable, connect the sensor to the web guiding system Make sure to thread the sensor connector all the way through to secure it in place. Next connect the power to the web guiding system using a pre configured power supply.

Once the web guide powers ON set it to automatic control and the web guide is ready for operation. NO other setup or calibration is required. The intelligent control system takes care of the rest of the settings for the sensor and the controller. We have spent the time on R&D so that you save every minute of your valuable time.

That’s how quick and easy it is to install our guide. All in less than 7 minutes. For more information please contact us.

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 setup. Now it features a comprehensive guiding sensor that can be used in any kind of sensing including edge, line, contrast, composite or layered web detection. In this video we use two web guides as a test machine to introduce several speeds and disturbance frequencies. One web guide creates a disturbance while the other correct this disturbance.

This test allows us to evaluate how our machine adjust to these different disturbances. This video shows contrast guiding of composite web where the web is guided based on a die cut of the label. Our web guides can work with continuous or intermittent lines or contrasted edge. Our edge sensor detects the web position of any materials used without the need for manual adjustments.

A previous version of our sensor used a reflection of infrared light to take a picture of the edge of the material. These pictures and processed using digital signal processing algorithms to accurately sense the true position of the material irrespective of its physical properties. The updated version is more comprehensive and uses white light to take a picture of the web materials and in the line detection mode, the sensor can handle a solid or intermittent line or even in contrast between two materials. As you can see this video, the web guide is unaffected by missing labels.

Our tests have shown our sensor technology works automatically with materials of varying contrast. The use of fiber-optic technology eliminates a need for focusing and eliminates need for calibration and set-up. There are details on these experiments available in our white papers. You can find a link in our description below.

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.

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
