DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

(7) In FIGS. 1 to 5 there is shown a block machine 1 according to the invention in several views and operating states. The block machine 1 has a machine bed 2, 3 with a movable main frame 2 and a static frame 3. A mould lifting device 4 and a tamper lifting device 5 are arranged at the movable frame 2. With the mould lifting device 4 and the tamper lifting device 5 a mould supporting member 6 and a tamper supporting member 7, respectively, are movably supported on the machine bed 2, 3 via linear guides. For that, in the block machine according to the invention there are used shaft guides with other types of linear guides also being applicable.

(8) As can be seen in particular in FIG. 1, the linear guide of the mould supporting member 6 includes two first longitudinal guiding members 8a and two second longitudinal guiding members 9a which are diagonally opposite on the machine bed 2, 3. The same applies to the linear guide of the tamper supporting member 7 that also includes two first longitudinal guiding members 8b and two second longitudinal guiding members 9b, with the first longitudinal guiding members 8b of the tamper supporting member 7 corresponding to the second longitudinal guiding members 9a of the mould supporting member 6 and vice verse. For simplicity, the linear guides now are explained in more detail with reference to only one first longitudinal guiding member 8a, 8b and one second longitudinal guiding member 9a, 9b each.

(9) As illustrated in the sectional views of FIGS. 2 to 5, the first longitudinal guiding member 8a of the mould supporting member 6 is attached thereto via a releasable locking means 16, for example via a lockable jaw guiding. The mould supporting member 6 is guided via a supporting member guiding means 14 at the second longitudinal guiding member 9a of the mould supporting member 6, wherein the supporting member guiding means 14 can be designed for example as lockable jaw guiding or as a slide bearing.

(10) The linear guide of the tamper supporting member 7 has lockable guiding means 17 to which the first longitudinal guiding member 8b of the tamper supporting member 7 is attacked. For example, the releasable locking means 17 can be a lockable jaw guiding. The tamper supporting member 7 is guided at the second longitudinal guiding member 9b of the tamper supporting member 7 via a supporting member guiding means 15 that also can be designed as a lockable jaw guiding or as a slide bearing, for example.

(11) The first longitudinal guiding member 8a, 8b and the second longitudinal guiding member 9a, 9b of the mould supporting member 6 and the tamper supporting member 7, respectively, are guided in two bed guiding means 10, 11, 12, 13 each. For example, these bed guiding means 10, 11, 12, 13 can be designed as slide bearing. The upper bed guiding means 10, 11 are arranged at the movable frame 2 and the lower bed guiding means 12, 13 are arranged at the static frame 3. As can be seen from FIGS. 2 to 5, the bed guiding means 10, 11, 12, 13 are always spaced apart from the supporting member guiding means 14, 15 and the releasable locking means 16, 17, respectively. This not only results in guiding points for guiding the mould supporting member 6 and the tamper supporting member 7, respectively, that are substantially arranged on one height, but also guiding points that are arranged vertically spaced apart. Thus, in the guiding direction (here, in the vertical direction) there is a wide spread of the bearing or guiding, respectively, of the mould supporting member 6 and the tamper supporting member 7, respectively, by utilizing the total height of the block machine 1.

(12) For moving the mould supporting member 6 the mould lifting device 4 has two mould lifting cylinders 18 directly acting on the mould supporting member 6. The mould lifting cylinders 18 each are laterally arranged at the movable frame 2 of the block machine 1 between a first longitudinal guiding member 8a and a second longitudinal guiding member 9a of the mould supporting member 6, as can be seen in particular in FIG. 1.

(13) For moving the tamper supporting member 7 the tamper lifting device 5 has a tamper lifting cylinder 19 that is centrally arranged at the movable frame 2 of the block machine 1, wherein the tamper lifting cylinder 19 directly acts on the tamper supporting member 7. Since by the movement of the tamper supporting member 7 also the first longitudinal guiding members 8b are moved two recesses 20 are below the static frame 3 into which the first longitudinal guiding members 8b protrude with the tamper supporting member 7 being lowered (see, FIGS. 4 and 5). However, it is also quite possible to choose the height of the static frame 3 such that the recesses 20 can be omitted.

(14) In the following now with reference to an example the production of the moulded articles 21 with a block machine 1 according to the invention and the corresponding movements of the mould supporting member 6 and the tamper supporting member 7, respectively, are described.

(15) First, the block machine 1 is fed with a bolster pallet 22. The bolster pallet 22 stops centrally in the block machine 1, often on a vibrator table unit. Subsequently, an upwards and downwards open stone mould 23 is lowered onto the bolster pallet 22. For that, the stone mould 23 is attached to the mould supporting member 6. By actuating the mould lifting cylinder 18 the mould supporting member 6 is lowered. Here, also the first longitudinal guiding members 8a are moved, since these are attached to the mould supporting member 6 via the releasable locking means 16. The second longitudinal guiding members 9a do not move, with the mould supporting member 6 being guided thereon by means of the guiding means 14. Subsequently, concrete is filled into the mould cavities of the stone mould 23 via feedboxes. This state with filled mould cavities of the stone mould 23 is illustrated in FIGS. 2 and 3.

(16) After the stone mould 23 has been filled, the tamper supporting member 7 is lowered, so that the tampers 24 attached to the tamper supporting member 7 pack the concrete in the stone mould 23. Additionally, but also alternatively, packing the concrete can be performed by vertical excitation by means of the vibrating table unit. The movement of the tamper supporting member 7 is performed by actuating the tamper lifting cylinder 19. Since the first longitudinal guiding members 8b, which at the same time are the second longitudinal guiding members 9a of the mould supporting member 6, are attached to the tamper supporting member 7 via the releasable locking means 17 they are also moved with the movement of the tamper supporting member 7. Here, the second longitudinal guiding members 9b, which at the same time are the first longitudinal guiding members 8a of the mould supporting member 6, are not moved, since the tamper supporting member 7 is movably supported thereon via the guiding means 15. When the tamper supporting member 7 is completely lowered and the tampers 24 have packed the concrete in the mould cavities of the stone mould 23, the lower ends of the first longitudinal guiding member 8b of the tamper supporting member 7 protrude into the recesses 20. This state is illustrated in FIGS. 4 and 5.

(17) Then, first the tamper supporting member 7 is lifted again, wherein also the first longitudinal guiding members 8b of the tamper supporting member 7 are moved again. Subsequently, the stone mould 23 is lifted from the bolster pallet 22 by lifting the mould supporting member 6, and the moulded articles 21 are removed. Here, also the first longitudinal guiding members 8a of the mould supporting member 6 are moved again. Then, the bolster pallet 22 with the moulded articles 21 can be taken out of the block machine 1 and supplied to the subsequent processes.
