Grated Cheese Sorted By Weight with Checkweigher and Metal Detector

Are you searching for an inline metal detectors. This is a combination metal detector and check weigher used to check grated cheese containers. The unit features stainless steel wash down construction and ensures all containers leaving the facility are within acceptable limits for weight and metal contamination. Containers first pass through the metal detector, which can sense small metal fragments and signal the system to reject contaminated product down-line. We maintain a metal-free zone around the metal detector, so that the conveyor frame does not interfere with the metal sensing apparatus. Notice how the motor is mounted far away from the metal detector so that electro-magnetic fields do not interfere with it. The belt running through the metal detector also functions as the infeed conveyor for the scale.

The infeed conveyor belt and conveyor scale belt are running at the exact same speed to reduce product vibration as product transfers onto the scale. Photo eyes detect the leading edge of the container and the weighment cycle begins. The cycle stops once the container reaches the second photo eye. If a container is outside of the desired weight range, the operator-side divert activates to remove product from the line. If metal is detected, the opposite divert activates. The dual divert setup allows floor personnel to know which product has metal contamination or is out of the predetermined weight range. These five containers are all filled to the proper weight range.

These two containers do not contain enough grated cheese product and are too light and the last container has metal particles in it. The five correctly filled containers have acceptable parameters and continue down-line. The next two under-filled containers are diverted as they are not within the proper weight range. The final container has metal contaminants and is diverted to the metal contamination bin. So what happens if a container has metal and is not within the proper weight range? Those containers are diverted into the metal contamination bin as product containing metal must be inspected and discarded.

All of these functions are controlled by our Scale Data System touch screen controller. The controller tracks weight information for each product. The operator can easily change the product type so that production information can be viewed for each product as it is being run. The controller stores information such as total weight, total number of containers, average weight of the containers, number of containers rejected, and the number of containers accepted for each product run. Using this system will give the producer confidence in knowing all containers leaving the facility are within acceptable limits for weight and metal contamination.

Understanding the Science

We have people who model coils for the hipper expertise in electromagnetic modeling. We developed algorithms and a lot of people specialize in signal processing and this is a big part of what you do. We have people doing electronics design or require very precise electronics. So we have a both analog and digital engineers. What are some of the biggest challenges you face because you know my next race is to detect to make the doctors at perform well in real ground conditions is relatively easy to make a detector that will detect deep in a but when it comes to detecting or identifying targets in difficult ground conditions that it’s a completely different problem. How do we go about that well.

First we have a really good understanding of what grounds look like and what targets look like but then we do a lot of testing with you develop our algorithms and then we got and testing with Justin first on the lanes because it’s convenient and then we go in real ground conditions in various places. In Australia overseas software is a big part of detectives these days with their James you to explain to us a bit more. So what’s involved James the detectors themselves generally contain code from c++ but we use a range of other languages to support our development things like Python and love you so what are the steps that are involved. The first place is to gather all the requirements of what the product needs to do. The second phase is the design and development where we come up with a an architecture for the product software and make way for the signal processing algorithms that come out.
