20100095854 | DEVICE FOR PRODUCING COMPRESSED BALLS - The invention relates to a device for producing compressed bales from compressible pressed product pieces, each compressed bale produced having a cuboid form with edge lengths A, B and C. The device includes a press housing having at least one press chamber and a press shield that can be moved in the press chamber in the press direction and back by means of a mechanical drive. The press chamber has a cross-sectional surface of A×C/n. In the press chamber, n partial compressed bales can be produced in n first press steps, with a flat cuboid form with the edge lengths A, B and C/n. A storage space is arranged downstream from the press chamber, n partial compressed bales being transferable into the storage space. The partial compressed bales can be joined in the storage space to form the cuboid compressed bales with the edge lengths A, B and C. The press chamber is separated from the storage space by a mobile partition, and an opening-that can be freed by the partition has at least the dimension A×B in the opening position, such that a partial compressed bale formed in the press chamber can be transported into the storage space through the opening. | 04-22-2010 |
20100095857 | PRESS HAVING A LOADING DEVICE AND A DEVICE FOR OPENING AND REMOVING GOOD PIECES - The invention relates to a press having a loading device, wherein the press is configured particularly for pressing the pressing product forming residual or recyclable materials, such as used paper, cardboard, plastic bottles, foils and the like, and has a press housing including a pressing chamber, having a loading opening for feeding the pressing product and a pressing shield displaceable in the pressing chamber, wherein the loading device includes at least one rotatably driveable rotor roller equipped with conveying prongs. By means of a rotation of the roller pressing product can be conveyed from the outside of the press housing through the loading opening into the pressing chamber. The press has the rotor roller is disposed directly in front of or in the loading opening of the press. The loading device has a feeding space connected upstream of the rotor roller. The pressing product to be pressed can be placed or thrown into the space and wherein the pressing product can be removed from the same by the rotor roller directly into the pressing chamber. | 04-22-2010 |

When the collector wagon is coupled to the press, the collected compressible material is mechanically transferred from the collector wagon into the press chamber, after movement of the floor and use of a feeder device. When uncoupled from the press, the collector wagon is filled with compressible material at a location at a distance from the press. The feeder device is designed such that the compressible material to be pressed present in the collector wagon, after the upward movement of at least the floor, is gradually gripped and continuously removed from the collector wagon from above, and fed to the press. | 09-20-2012 |
