Method and device for distributing a predetermined mass of a product

摘要

The procedure for distribution of a pre-determined discharge mass of a material during a discharge cycle on a product surface of an intermediate product, comprises conveying the material along a supply direction (ZR) by a supply device (5), conveying the intermediate product by a product conveyer (9) along a product conveying direction (PR) and determining the mass of the material conveying on the supply direction depend upon the interval of the material from a dropping edge (5AR) of the supply direction. The procedure for distribution of a pre-determined discharge mass of a material during a discharge cycle on a product surface of an intermediate product, comprises conveying the material along a supply direction (ZR) by a supply device (5), conveying the intermediate product by a product conveyer (9) along a product conveying direction (PR), determining the mass of the material conveying on the supply direction depend upon the interval of the material from a dropping edge (5AR) of the supply direction, directing a conveying length (FL) corresponding to the discharge mass in the discharge cycle from the supply direction, directing the discharge mass through a guiding duct from the surface of the intermediate product, creating a coordination between target surfaces (3PS i) of the product surface for the material and for distributing partial mass (m) of the discharge mass, directing the freely falling discharge mass against a driven redirecting unit for the material and redirecting the material with the help of redirecting unit through the guiding duct of the product surface. For each partial mass, a redirecting angle of the redirecting unit is determined such a way that the each partial mass is diverted on its accompanying target surface until the discharge mass is conveyed. In the creation of the coordination, the product surface is subdivided in product surface strips passing vertically to product conveying direction as target surface, and the discharge mass supplied by the supplying device is subdivided in partial mass or a conveying length is subdivided in segments of the partial mass corresponding to the discharge mass. Each partial mass is assigned a product surface strip as target surface or each product surface strip is assigned a partial mass of the discharge mass that overlies on a partial section (FL i) of the conveying length. The redirecting angle for redirecting a partial mass on a product surface strip is calculated with the help of impulse law or determined with the help of experimental determination. Each product surface strip is reduced to a line or a point passing diagonally to the product conveying direction for calculating the strip. The redirecting angle assigns in a given conveying speed of the supply device. All product surface strips are occupied uniformly and strong with the material. The product surface strip has a width of less than 1% or less than 0.1% that corresponds to a product length of the intermediate product in the product conveying direction. An independent claim is included for a device for distribution of a pre-determined discharge mass of a material during a discharge cycle on a product surface of an intermediate product.
