  • Patent number: 11999578
    Abstract: A palletizing apparatus and a method for stacking packages on a load carrier. The palletizing apparatus has a stacking location for palletizing the packages and at least two supply stations, which are in conveying connection with the stacking location and each have an intermediate carrier formed for receiving the packages. It is possible for the intermediate carriers to be vertically adjusted by a motor at least to some extent independently of one another between a low-level position and a high-level position. In order to make a rapid palletizing cycle possible, provision is made for the intermediate carriers to be horizontally adjustable by a motor-drive independently of one another between a starting position and an end position. The intermediate carriers are arranged at the supply stations for adjustment in a collision-free manner in opposite adjustment directions between a receiving position and a transfer position.

  • Patent number: 11912735
    Abstract: Disclosed is a method for purifying sialylated oligosaccharides from a fermentation broth, cell-lysate or biocatalytic reaction mixture for obtaining high amounts of desired sialylated oligosaccharides in high purity. The method is particular suitable for the large-scale economic purification of sialylated human milk oligosaccharides (such as 3?-sialyllactose, 6?-sialyllactose or sialylated lacto-N-tetraose derivatives) from microbial fermentation, using recombinant bacterial cells or yeast cells. The obtained material is of high purity and can be used for food or medical application such like medical nutrition products, infant formula, dietary supplements, general nutrition products (e.g. dairy drinks).

  • Publication number: 20230399180
    Abstract: A method and device for grouping packages into specified package groups in an interference-free and fault-free manner with a conveyor having multiple individually actuatable conveyors arranged one behind the other with an inlet-side and a discharge-side end. The packages are supplied to the conveyor device at the inlet-side end one after the other, and a control algorithm is carried out to interpolate and/or detect the position and/or the speed of each individual package. A target speed is determined for each individual package based on the detected and/or interpolated position and/or speed of the package. A target speed is determined for the individual conveyors to achieve the target speed for each package to set a specified distance to the leading and/or following package at the discharge-side end. The speed of the individual conveyors is controlled to the respective determined target speed for the conveyor.

  • Publication number: 20230211959
    Abstract: A system for assembling layers of packages and for forming transport and storage units from the layers. A grouping station has a grouping table for arranging and grouping the packages in a predefined layer arrangement. A package delivery feeds the packages to the grouping table in a conveying direction. The package delivery has two row conveyors for transporting at least one row of packages each on either side of the grouping table. A transfer unit transfers the packages from the row conveyors to the grouping table by sliding them in a respective sliding direction over a slide-over buffer region between each row conveyor and the grouping table, in order to form the layer of packages. A layer stacker then slides the layer of packages from the grouping table over onto a plate provided in the layer stacker, while maintaining the layer arrangement, in order to form the transport and storage unit.

  • Publication number: 20210371160
    Abstract: A plate for use with a transport-and-storage unit includes a plate-shaped body having a stable form for receiving a layer formed from packages or groups of packages. The body has a planer upper side and a planar underside opposite each other. A holder is provided on at least part of the underside's perimeter.
