Abstract: A core puller device for a block machine, a block machine with such a device as well as a method for the preparation of shaped stones in which at least one core puller arranged on the sliding facility of the core puller device is temporarily inserted into a stone mould of the block machine and retracted after a packing operation in the block machine are provided. Here, the core puller device is constructed or the method is configured such that the operative connection between the at least one core puller and the sliding facility of the core puller device is temporarily neutralized.

Abstract: The invention relates to a concrete block producing device and to a method for producing colored concrete blocks using a concrete block producing device including a block molding machine with a block mold that can be supplied with fresh concrete from a concrete hopper. The concrete hopper can be supplied with portions of at least two differently colored fresh concretes in a controlled manner by a dosing device. The dosing device includes at least two dosing chambers and a transport device for transporting the differently colored fresh concrete portions to the concrete hopper. The transport device includes at least one positioning unit for guiding the colored fresh concrete from the dosing chambers to the concrete hopper. The positioning unit is designed to supply defined positions in the concrete hopper with differently colored fresh concrete portions.

Abstract: The present invention relates to a block machine (1) with a machine bed (2, 3) at which at least one lifting device (4, 5) for a supporting member (6, 7) is arranged. The supporting member (6, 7) is movably supported on the machine bed (2, 3) via a linear guide which has at least one longitudinal guiding member (8a, 8b, 9a, 9b) and a guiding means (10, 11, 12, 13, 14, 15) interacting therewith. To the supporting member (6, 7) there is attached a first longitudinal guiding member (8a, 8b) that is movably supported via at least one bed guiding means (10, 11, 12, 13) that is arranged at the machine bed (2, 3). At the machine bed (2, 3) a second longitudinal guiding member (9a, 9b) is arranged on which the supporting member (6, 7) is movably supported by a supporting member guiding means (14, 15) arranged thereon.

Abstract: The invention relates to a block molding machine (1) comprising a bearing block (3) and a primary frame (2) which can be locked on the bearing block (3) in a vertically adjustable manner. At least one mold lifting device (19) for lifting and lowering a block mold (20) is provided on the primary frame (2). The primary frame (2) can be displaced relative to the bearing block (3) by actuating the mold lifting device (19) which is supported on the bearing block (3). The invention further relates to a method for vertically adjusting a block molding machine (1), comprising the following steps: displacing a mold lifting device (19) to a position (AS) supported on a bearing block (3); releasing a primary frame locking unit (9) for the primary frame (2); actuating the mold lifting device (19) such that the primary frame (2) is lifted; and applying the primary frame locking unit (9) for the primary frame (2).

Abstract: A shuttle for a feedbox of a block machine has a shuttle slide with shuttle rodding. The shuttle slide connects to the drive via a connecting rod. The connecting rod has an interconnecting bar, an articulated swing arm, and a driving reciprocating link connected to the drive. The interconnecting bar is attached to the shuttle slide via a first articulation and to the articulated swing arm via a second articulation. The articulated swing arm is attached to a static bearing via a third articulation. The driving reciprocating link is attached to the articulated swing arm via a fourth articulation.

Abstract: A device for transporting and shaking blanks supported on pallets has a shaking station with a shaking table, a feeding conveyor upstream of the shaking station in a transport direction of the blanks, and a discharge conveyor downstream of the shaking station in the transport direction of the blanks. The feeding and discharge conveyors each have a liftable and lowerable transport frame and a drive. The transport frames are movable back and forth by the drive for transporting the pallets. The drives are adjustable to an identical intermittent transport distance and an intermittent transport distance in a ratio of 2:1. On the transport frame of the discharge conveyor a support is provided in an area adjacent to the shaking station. The support raises the discharge conveyor's receiving surface for the pallets and has a receiving surface aligned approximately with a table top of the shaking table.
