They are designed for dosing products in hard state, moving as "free fall". "Free fall" means the uniform movement of the product on transport vibrators and empty the dosing buckets with constant speed and capacity.      Depending on product type and desired dose range, there are differences in mechanical construction and system software settings. The linear weigh system works flawlessly and with guaranteed accuracy, when used for dosing the products in a dose range it's designed for.     Technical specification 1 feeding device 2 transport vibrators 3 holding brushes 4 dosing buckets 5 weight sensors 6 air apportioners 7 sliding rule for flow control The DGL series are made in several different modifications, depending on the volume and weight of dosed product and desired system performance. The main differences are in the volume of the weight buckets, the range of weight sensors,  number of cascades in transport vibrators and the proportion between widths of holding brushes.    Modifications and performance DGL-21 Single cascade with 3 tracks   DGL-41 Single cascade with 4 tracks DGL-23 Triple cascade with 2  tracks   DGL-43 Triple cascade with 4 tracks DGL-21 20 doses/min. DGL-23 20 doses/min. DGL-41 40 doses/min. DGL-43 40 doses/min.    Operation principle The DGL series dosage devices offers a choice between two kinds of dosing - automatic and manual.  The automatic mode is the better option in most cases, since it's designed to provide maximum efficiency. It's function is to determine the "switch levels" ensuring thereby a minimum possible dosing time at maximum system accuracy. On system start up the first doses produced are different from programmed values. After 10 to 20 dosing cycles and establishing a constant product flow, the system goes into stable operating mode and starts to dose in programmed range. The automatic option is kind of self-learning mode for dosing device and when it's used there is no need to try different dose range values to achieve best results and to change them when you decide to pack a different product. On activated manual mode, the linear weight system continuously counts the incoming in weight bucket product and when certain weight is reached the dosing mechanism is stopped. After the final weight assessment a "dose ready" signal is send to controller of packaging machine and packet is made. This process is repeated constantly. To achieve higher speed and accuracy of linear dosing system there are two operation speeds available - high and low. Both are used to make a single dose. In the begging of the dosage process the main quantity of product is delivered to weight bucket at high speed. At this stage, due to this reason, the dose of the product is inaccurate, so the system performs a second, supplementary delivery on lower speed, fine adjusting the dose to fit the programmed values.
