The Green sorting receives lumber from the saw and sort it by dimension.
After sorting, sticks are placed between the layers of lumber in the packages. Thereafter there is an option to place dunnage on the packages that will be stacked in the Kiln dryer. Green sorting's from CGV ensures an effective management of newly sawn lumber and can be adjusted after capacity and operators.
Lumber can be sorted by dimension alone or by various levels of scanning systems.
The intake between the saw line and the green sorter plays a very important role in today's highly efficient sawmills. A buffering facility is often needed to handle short stops in the green sorter without the sawline having to stop. After the stoppage has been resolved, the buffer is emptied at the same time as the online flow from the sawline can be received and sorted in the green sorter.

Our fastest Lug loader consists of a rotating drum on which there are tongs that grabs the lumber piece and controllably transfers it to the lug chains. We also have other solutions with simpler Lug loaders for a lower capacity.

Bin sorter is a solution that apart from being affordable, effectively utilize the available space. We can offer two different types of Bin sorters, one with electrical regulation of the bottom hatch and one with hydraulic regulation.

The Positioning fence is used to transport and position the lumber pieces so it can be cut precisely as calculated by the optimization. CGV have different designs and variations for the Positioning fence depending on speed and stroke.

CGV has two proven trimmers where capacity and cost determine the choice of trimmer. Both trimmers have a design that provides low maintenance costs and high efficiency.

A robust construction with a pusher lug for a capacity with over 200 lugs/minute. When bins are emptied there are support arms being extended on both sides to compress the packages while it is emptied on a conveyor.

CGV have delivered Tray sorters since 1986 which at the time had a top speed of 70 pieces per minute. Since then the system has been further developed to for example high-speed planer mills and the production rate is now over 200 pieces per minute.

Our machines for sticker stacking have been developed with a focus on capacity, efficiency, and simplicity for the operator. We drew inspiration from Nc-controlled machines in engineering workshops, which means that most movements are fully synchronized with each other. This type of controlling is simplified through our control system which has an integrated motion controller in the PLC. Movements are calculated with the optimal run profile automatically, which reduces the number of recipe parameters and simplifies adjustments for the sticker stacker. Resulting in a more exact machine that can be run with smaller margins and more efficient.

Our sticker stacker have been developed with a focus on capacity, efficiency and ease of use. The inspiration comes from NC-controlled machines in the engineering industry, which means that the machine work with most movements completely synchronized with each other. This way of controlling our machines is simplified by the fact that our control systems have an integrated motion controller in the PLC. The movements are calculated with the optimal driving profile automatically, which reduces the number of recipe parameters and makes the sticker stacker easy to set up. The result is that the machine is more precise and can be run with smaller margins and better efficiency.

It is becoming increasingly more important with a good drying result to increase the quality of the final product, one of the factors is that there are enough drying sticks in the package. With an increased amount of sticks it is natural to automate the process of laying sticks on the package, another important factor is the removal of defective sticks that would otherwise influence the drying result or cause disturbance in the production. CGV have well proven concepts for this.

With the Stick automat from CGV, upwards three sticks can be distributed at a time to a buffer in each cassette. Sticks are then placed on the packages from the buffer with a servo-controlled placement frame. In the case where the stick automat is connected to our Nc-controlled layer stacker, the stick automat can be programmed with a movement profile which will synchronize with the stacker.

A Dunnage automat is often placed in spaces without heat, which can be particularly challenging for pneumatics and hydraulics during the winter. That is why we at CGV have constructed our Dunnage automat with solely electrical components, in order to yield the highest possible availability. The placement frame has adjustable height so that dunnage can be placed on packages without full height.
