The technique of 3D image acquisition has been around for more than twenty years, but the demand for its application has been limited. The market is apparently not so busy until now, but that seems to change. In the past three months, we have received the question: ‘Can you control my machine variably by means of a line scan?’

Conventional automation assumes a predictable product position, for example a precisely known location of a product or packaging on a conveyor belt. The processing on the product can be done blindly, because the position and orientation are known. The result is self-evident and always exactly the same, that is what you can do with automated processes. The downside of these advantages lies in the limitation it imposes on the product supply, which must be such that every product ends up on the tape in the right way.

What if I cannot or no longer want to organize?

For successful processing of random lying products on a conveyor belt, one can think of steering by means of a line scan.

Control by means of a line scan

Line scan is technically not the right word, but popularly a commonly used translation for laser triangulation. The word describes perfectly what we see as human beings: a laser line that scans the passing product. What we call the process does not matter, it’s about the result. From the scan follows a so-called point cloud that forms a three-dimensional model of the scanned product. For that you will be having the best line scan camera now.

The software made for your process gets relevant information from this point cloud

This can be a pick-up point, a place where you have to print, a cut line to open a bag, you can say it.Of course, the system still makes some demands on the product position, so the recognizable detail must be visible from the laser and camera position. That is immediately the only requirement, for the rest it is free. And it does not make the scanner – within a certain range – look at whether a small or large product is looked at, the system is also flexible here, without changing or replacing product-specific holders, guides or molds.

The nice thing about using laser light is that the system is relatively insensitive to ambient light. This is due to the fact that the camera receives a special filter which only transmits the wavelength of the laser source, a so-called bandpassfilter. The light output to be applied is so low in almost all cases that laser safety does not require special measures.Because the position of the camera in relation to the laser source is very important, we build it together on one frame. This is then incorporated in an enclosure that we can optionally run in aluminum or stainless steel and in any desired IP value, whether or not carried out in food grade.

For processes with a strongly changing ambient temperature, additional measures are taken by smart material choices that ensure the calibrated set-up under all temperatures.

Frogans technology is advancement in the top level domains that are used by a number of people today. This technology allows the implementation of a new layer of application on the internet. This application layer is called as the frogans layer. This can be added along with the other layers that are very common such as the World Wide Web or the email. Frogans technology is said to be very simple to use and also very safe. This technology allows for the Frogans sites to be published. This site is made up of a set of pages that are hyperlinked with each other. These linked pages are then put on line on the internet. They can also be done on an intranet. This whole process can be done on a Frogans address. These sites can be easily published by anyone. The standards that are used in the Frogans technology are very safe and are free and open to everyone. Frogans layer is to be introduced in the near future on the internet. Used Servers

Uses of Frogans technology

This technology can be used with the aim of providing security, reliability and stability of the Frogans layers that will benefit all the users of the internet. The computers that are dedicated solely to the functioning of the certain layers on the internet can be used for the distribution of free software applications. These applications will let the internet users to navigate all through the Frogans layers. Frogans addresses that are available on the particular layers form the basis of its global addressing system. They have a simple pattern that is specific which is in no way related to the URI scheme. The use of Frogans layers sticks to the principles of ICANN in order to keep the internet sites safe and interoperable. They also help in keeping the sites stable at all times. This also encourages a great deal of innovation in the internet. Bylaws that are available to the public consist of the detailed list of all works that must be accomplished by the OP3FT in order to fulfill its mission.
Laser allows you to mark any medical device with any type of code (barcodes, data matrix codes, serial numbers, etc.). Check out laser marking on steel on this webpage for information.
