Problems solved by technology

Reset can be done via the interface (external product reset) or a binary signal, but standard practice is for the operator to manually reset the scale, which can lead to manipulation or misadjustment, and is almost always the same in practice as the scale itself. There is no direct and clear link to the corresponding product conveyed on the heavy

Embodiment Construction

[0033] The embodiment of the weighing system represented schematically in Figure 1 shows a basic frame 2 with adjustable height supporting feet 1 standing on the floor, on which a conveyor belt 3 is fed, acting as a measurement line The weighing conveyor belt 4 and the unloading conveyor belt 5 are continuously arranged in a horizontal alignment. The three conveyor belts 3, 4 and 5 are directed in the same direction and circulate at the same speed on two horizontally spaced rollers, each of which, namely rollers 6, 7 and 8, is driven by a motor 9, 10 and 11 respectively drive. These motors are controlled so that the same belt speed setting can be guaranteed for all three belts 3 , 4 and 5 .

[0034] A weighing conveyor 4 serving as a measuring conveyor line is supported on a weighing cell 12 , which is fastened to the basic frame 2 . With respect to the transport direction at the infeed conveyor 3, the products to be weighed 13 are loaded one by one on the entry side on the ...

Abstract

The invention relates to a method for weighing a product, whereby the product is conveyed along a measurement line and an actual weight value is determined for said product. According to the invention, said product is provided with a transponder and an exchange of data is carried out with said transponder.

Description

technical field [0001] The present invention relates to a method of weighing products, by means of which the products are conveyed along a measuring conveyor line and the actual weight value of said products is determined. Background technique [0002] Such existing methods are used to check the weight of products sold. If the product weight deviates from the target weight specified for that product type by more than the also specified tolerance value, the corresponding product is separated out after the weighing process by means of exclusion devices such as pushers, nozzles or deflectors. For this process, the target weights and corresponding tolerances for the respective product type of the product to be inspected generally have to be manually entered into the weighing system. In this way, a dynamic check scale with an exclusion device can ensure in legitimate commerce that those products that do not meet the tolerances prescribed by law (eg in Europe: Finished Packaging ...
