Patent number: 5678697Abstract: A sorting installation for useful products is proposed, which serves in particular to sort out reusable packaging materials. In order to achieve the sorting-out of individual types of packaging with maximum efficiency, the sorting-out of individual monofractions is undertaken, on one or more manual sorting sections, onto a collector conveyor belt which is connected in parallel, the content of which, after sorting-out is complete, is introduced into an associated bunker.Type: GrantFiled: January 5, 1995Date of Patent: October 21, 1997Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventors: Dieter Fuchs, Wolfgang Stehle

Patent number: 5333738Abstract: A method is proposed for recovering valuable substances, particularly from construction site wastes and industrial trash as well as a system for implementing the method in which the essential sorters are disposed in a closed container which can be placed onto an elevated foundation. The foundation is formed by intersecting walls which simultaneously serve as partitions for various bunkers.Type: GrantFiled: October 4, 1991Date of Patent: August 2, 1994Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventors: Dieter Fuchs, Peter Strohhacker

Patent number: 4964577Abstract: The invention relates to a process for dividing up and recovering the individual materials from old cables. For this purpose, the cable mixture is sorted into individual constituents and cut to size, the outer plastic sheath is removed by being slit open, and the individual cores are fed to a disk comminuter. It is essential, at the same time, that the disk comminuter should cut up the individual plastic-sheathed cables or the cable composed of several individual cables into short cable pieces of a length of 3 to 10 mm in a salami-like manner. Because the pieces are very short, the short cable pins are separated from the plastic ring arranged round them on a following vibrating screen.Type: GrantFiled: July 7, 1989Date of Patent: October 23, 1990Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventor: Wilhelm Kopp

Patent number: 4884700Abstract: A sorting machine which serves for treatment of mixtures of refuse, especially household rubbish, trade waste, industrial waste, refuse from demolition, waste from building sites, and also waste from wood or the like. To achieve a drum-like motion, a mixture of useful material is supplied to a conveyor belt which is inclined transversely to the direction of transport, the conveyor belt having the shape of part of a cylindrical shell. For the production of a screen effect, the screen conveyor belt is provided with screen pockets on its surface, so that fine material falling into the screen pockets is transported in the longitudinal direction of the screen conveyor belt, and coarse material is transported in the transverse direction of the screen conveyor belt, and thereby they are separated.Type: GrantFiled: October 28, 1987Date of Patent: December 5, 1989Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventors: Gunter Allgauer, Peter Strohhacker, Dieter Fuchs

Patent number: 4763793Abstract: A sorting installation for separating a first type of articles from a second type of articles fed mixed to the sorting installation. The articles of the first type are relatively light and substantially two-dimensional, while the articles of the second type are relatively heavy and substantially three-dimensional. There is provided an article-supporting surface which receives the first and second type of articles in a generally mixed state and which has a length dimension and a width dimension perpendicular to the length dimension. The article-supporting surface is inclined to the horizontal in a direction parallel to the width dimension for causing primarily the second type of articles to move by gravity downwardly on the article-supporting surface transversely to the length dimension and laterally off the article-supporting surface.Type: GrantFiled: December 11, 1985Date of Patent: August 16, 1988Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventors: Wolfgang Stehle, Dieter Fuchs

Patent number: 4760925Abstract: A sorting installation for separating a first type of articles (relatively light and substantially two-dimensional) from a second type of articles (relatively heavy and substantially three-dimensional), includes a travelling conveyor belt having an article-supporting surface receiving the first and second type of articles in a generally mixed state. The article-supporting surface is arranged for travel in its length dimension and is inclined to the horizontal in its width dimension for causing primarily the second type of articles to move by gravity downwardly and laterally off the article-supporting surface. The article-supporting surface slopes upwardly as viewed in a direction of travel. There is further provided a vibrator connected to the belt conveyor for enhancing movement by gravity of the second type of articles on the article-supporting surface.Type: GrantFiled: October 23, 1985Date of Patent: August 2, 1988Assignee: Maschinenfabrik Bezner GmbH & Co. KGInventors: Wolfgang Stehle, Dieter Fuchs

Patent number: 4693379Abstract: A screening apparatus, particularly for screening valuable materials, domestic garbage, industrial garbage, bulky garbage, dry garbage, wet garbage, compost and/or problematic and dangerous materials, including inclined, open-ended bars capable of oscillatory movement arranged in a transport direction and forming at least two bar grating screens forming a stepped arrangement of bar grating screens with one screen located behind the other in the transport direction. The bar grating screens have bars that are tapered in the transport direction. The apparatus further includes an inlet portion and a preliminary distributor path for feeding in material upstream of at least the upper bar grating screen of the stepped arrangement. A screen frame accommodates the bar grating screens, the inlet portion and the preliminary distributor path. The inlet portion and the preliminary distributor path comprise approximately one third of the entire length of the screening apparatus.Type: GrantFiled: October 23, 1985Date of Patent: September 15, 1987Assignee: Maschinenfabrik Bezner GmbH & Co.
