The invention relates to a Betonformlingherstellvorrichtung for producing concrete moldings in a molding device having an upwardly and downwardly open outer mold for laterally surrounding the concrete moldings and at least one upper molding device for molding the concrete moldings from above.

The object of the invention is to provide a compact, with relatively low material and space requirements built Betonformlingherstellvorrichtung in which concrete moldings with high product flexibility can be produced at a high cycle rate.

This object is achieved by a Betonformlingherstellvorrichtung with the features of the appended claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

The invention provides a concrete blank manufacturing apparatus for producing concrete preforms in a molding apparatus comprising an upper and lower open outer mold for surrounding the concrete moldings and at least one upper mold for molding the concrete moldings from above and at least one lower mold for supporting and / or molding the concrete moldings from underneath, wherein the concrete molding manufacturing apparatus is an upper Formeinrichtungsbewegungseinrichtung, which is designed for raising and lowering the at least one upper mold, preferably relative to the outer mold, and a lower mold moving means for moving, in particular raising and lowering, the at least one lower Forming device is formed relative to the outer mold, wherein the mold moving means for simultaneous attack on both mold devices at a common station arranged one above the other si nd.

The Betonformlingherstellvorrichtung is used for producing very different concrete moldings. These may be bricks or bricks made of concrete, concrete slabs, concrete rings, concrete rods, shaped bricks, curb stones, etc. in different dimensions and with very different shapes and colors.

The concrete moldings are molded in a molding apparatus. The molding apparatus to be used in the concrete molding manufacturing apparatus of the present invention has an upper and lower open outer shape formed depending on the contours of the concrete molding to be produced. Such an outer mold may have a trough-like structure without lid and bottom, and may be divided into a plurality of chambers for producing a single concrete molding having a single chamber or for simultaneously producing a plurality of concrete moldings.

Further, in the molding apparatus to be used in the concrete molding manufacturing apparatus of the present invention, at least one upper molding device is provided to form the concrete mass located in the outer mold from the upper side to a concrete molding. The at least one shaping device is shaped depending on the surface to be produced. If the outer shape is subdivided into a plurality of chambers, in particular a plurality of shaping devices, for example one per chamber, can be provided.

Furthermore, the molding device has at least one lower molding device with which the mass located in the outer mold can be formed from below. This lower forming device is formed depending on the surface to be produced and can be exchanged as needed, as the other parts of the molding apparatus. The pointing to the concrete mass surface may, for. B. smooth to form a smooth surface, but there are also different inclined or patterned surfaces conceivable. In particular, for producing inclined, patterned or striped lower surfaces, the lower formator mover is preferably configured to raise and lower the lower mold relative to the outer mold. Furthermore, a single lower shaping device can also be provided here, which lends itself in particular to an outer mold having only one chamber. However, it is also conceivable - in particular for an outer mold with a subdivision into a plurality of chambers - to provide a plurality of lower mold devices.

For example, the upper mold is formed by molds while the lower mold is formed by one or more dies.

In the concrete molding manufacturing apparatus according to the invention, an upper molding device moving device and a lower molding device moving device are now provided at a common station. The upper former mover serves to raise and lower the at least one upper former relative to the outer mold. The lower mold moving means is for moving the lower mold means and is preferably formed for raising and lowering the lower mold means relative to the outer mold. The two Former device moving means are formed at a common station for a simultaneous attack on the two mold devices and arranged one above the other.

For example, the concrete molding manufacturing apparatus has a hydraulic for moving the upper mold and a hydraulic for moving the lower mold. It can z. B. molds are pressed onto the upper surface of the concrete mass in the outer mold. By means of the lower molding device movement device, the at least one lower molding device can preferably be moved from the lower side relative to the outer mold. For example, dies or the same sub-molding devices can be adjusted in height within the outer mold. Alternatively or additionally, z. B. vibratory movements of the lower mold device (possibly also together with the outer mold) feasible.

The arrangement of the two mold moving means for moving both an upper mold and a lower mold preferably achieves a multifunctional shape with height flexibility of the top and bottom design molded products and, as a result, product flexibility when machined at only one common station. Ie. for example, that in a quadruple mold (an outer mold whose interior is divided into four chambers), for example, with a standard dimension of 50 × 25 cm, plates at different heights with interchangeability of the molds or plates with different design and structures, etc. can manufacture. But you can also make a curb, a trough stone, a facade stone, etc.

The lower mold moving means preferably allows different settling possibilities for settling the molded concrete moldings. For example, the lower former mover may be used to eject the molds from the outer mold. For example, for this purpose, the lower mold devices - for example, dies - lifted out of the outer mold by the lower mold device.

Then you can settle the corresponding lifted concrete moldings in very different ways. The Betonformlingherstellvorrichtung can z. B. be combined with so-called. Edgewise deductions, where the products are parked vertically on pallets and / or with so-called. Flat shelves, where per product, the products are placed flat on a pallet.

Particular advantages of preferred embodiments of the Betonformlingherstellvorrichtung are the possibilities of product flexibility, Einlegeflexibilität and a Füllflexibilität.

Such flexibility can be achieved in particular by the fact that the concrete for producing the concrete moldings can be compacted in very different ways. This compaction flexibility can be achieved by the two form device mover devices which simultaneously engage at the same station.

According to a particularly preferred embodiment, at least one of the Formeinrichtungsbewegungseinrichtungen is provided with a Rüttelwerk with which the associated molding device for compressing the introduced in the mold concrete by vibrating is vibrationally movable.

In a further preferred embodiment, one of the two Formeinrichtungsbewegseinrichtungen on the Rüttelwerk, wherein the other Formeinrichtungsbewegungseinrichtung is designed to exert a counter-pressure during shaking. For example, the lower mold moving device is provided with the vibrating mechanism, and the upper mold moving device with the upper molding device attached thereto serves as a load.

According to a further preferred embodiment, at least one of the Formeinrichtungsbewegungseinrichtungen is provided with a tamping or percussion. With such a tamping or percussion, the associated molding device for compacting the introduced concrete in the form by stamping z. B. abruptly moved up and down. For example, the upper molding device can be provided with a stamping unit, so as to stamp the concrete from above and thus to compact.

It is particularly preferred that the Betonformlingherstellvorrichtung can shake and stamp at a station, so that the concrete moldings can be compacted very flexible depending on the product to be produced.

In a concrete advantageous embodiment of such a Betonformlingherstellvorrichtung it is provided that the upper Formeinrichtungsbewegungseinrichtung the ramming or percussion and the lower Formeinrichtungsbewegungseinrichtung has the Rüttelwerk.

Due to the different possible densifications - from above or from below, by shaking or pounding - very different materials can be inserted. For example, you can Insert rebars in different shapes or paper or other release or retardant materials.

It is also possible to produce very different products with different layer structure. Accordingly, the concrete molding manufacturing apparatus is preferably very flexible in terms of filling the mold. For example, the machine can fill facing concrete down and core concrete above or vice versa core concrete below or header above. You can even fill in something different between the two layers.

In a particularly preferred embodiment of the invention, multifunctional shapes, settling flexibility, lay-in flexibility, and fill flexibility, as mentioned above, can be made on a single machine having a single outer shape at a station.

Thus, the machine is also suitable for a very compact and economical construction. For example, the Betonformlingherstellvorrichtung of the type in question can be used at the beginning of the construction of a concrete plant, the investment costs for molds and molds can be kept low and yet a relatively high clock rate can be achieved.

Preferably, as already briefly indicated above, the lower molding device moving means on an ejector for ejecting the concrete moldings from the outer mold.

According to a further preferred embodiment, it is provided that the outer shape is made multifunctional in that at least one of the mold devices is exchangeable, so that different upper mold devices and / or lower lower mold devices can be attached in the upper mold device moving device, in such a way that they are both preferably movable relative to the outer mold in order to form the concrete moldings at the top and / or bottom differently at a station.

• b) for moving the resting on the lower mold means concrete moldings together with the lower mold means and / or
• c) for pivoting the concrete moldings together with the lower mold device for setting up the concrete moldings

is trained.

The lower mold moving means is advantageously housed in or on a vibrating table provided with a vibrating mechanism for vibrating the lower forming means. In order to allow simultaneous attack of the two Formeinrichtungsbewegseinrichtungen in such a configuration, it is provided according to a further preferred embodiment that the upper Formeinrichtungsbewegungseinrichtung is mounted on a machine frame above the vibrating table to the upper mold from above into an outer mold resting on the support and out of this upward to move out again.

An advantageous embodiment of the Betonformlingherstellvorrichtung is formed by a multi-functional machine that offers many functions with respect to machines with successive processing halved cycle time and low setup time. With such a multifunction machine can be integrated in a machine type an extremely wide range of end products at the same time exceptional cycle or set-up times. Leave at existing plants for the production of concrete moldings Thus, new additional sales opportunities can be achieved either in exchange or even in addition to existing Steinform- or plate production cycles. For newly constructed systems, the multifunction machine is available as an entry-level version or as a dismounted version is a real alternative to block forming machines, turntables and sliding tables.

An advantage of a preferred embodiment of the Betonformlingherstellvorrichtung is the height flexibility of the thus produced concrete moldings and the molds used. For example, standard heights of 2/4 cm to 8/10 cm, optionally up to 22 cm can be achieved. All of these values are approximate, different values are possible. Preferably, 6 cm to 8 cm height difference can be optionally adjusted from a control panel. A filling height adjustment is preferably possible in the range of 1-10 mm range. This can be achieved in particular by adjusting the height of the lower mold device relative to the outer mold.

According to a preferred embodiment of the invention, the upper shaping device has at least one impact sheet or load and the lower molding device has at least one die. In particular, with such an embodiment, a design flexibility can be achieved, whereby a design from above and through the die a design from below can be reached by the impact sheet load. Optionally, walls of the outer mold can also be adjusted as lateral molding devices with at least one lateral molding device moving device, for example hydraulically. With appropriate shaping of the lateral shaping devices can then allow a design from the side. Preferably, the parallelism of each product can be adjusted during filling.

A particular advantage of handling multiple pages at a station is the product flexibility of the molds. Thus, with a single quadruple form fourfold, z. B. in the sizes 50 cm × 25 cm (length × width) are produced: Plates in flexible height, with flexible structures such. B. Fälz-, split, tile or plaster structure and finishes such. a. Washing, blasting, brushing, sanding, coating and polishing. With a height up to 21 cm can then be 25 cm wide bricks z. B. in 85 mm, 140 mm or 215 mm in height. In addition, trough stones, for example of dimensions 50 cm × 25 cm, in flexible thickness, board or curbs in the appropriate width and length dimensions with flexible board and edge stone design and flexible thickness, wall coverings, for example, flat, sloping or with a pitched roof including water nose , also in the appropriate length and width or full blocks z. B. with the dimensions 50 × 25 in z. B. 20 cm in height. Likewise, bricks are possible with projection-recess engagement structures (eg in the manner of a Lego stone) with elevations on one side and depressions on the opposite side. Unique is now also the compression of extremely fine material to produce excellent facade stones with natural sand look with the appropriate length and width in flexible thickness for building construction; Furthermore, handrails for stairs with double-sided design and design on both sides and much more are possible.

The achievable by the advantageous embodiment Einlegeflexibilität allows the production of reinforced products (concrete moldings) such. Cable duct covers, cable cover plates, balcony spacer plates and computer rooms. Likewise, detergent products are possible by means of retarder paper. A new development producible with an advantageous embodiment of the concrete molding production device is an reinforced sandwich stone with the layers of design attachment, insulation (eg polystyrene or glass foam) and core concrete, wherein both concretes are connected by reinforcing bars.

The proposed in a particularly preferred embodiment of the invention combination of compaction and the compaction flexibility allows in addition to a compaction z. B. by four hammers and a direct compression z. B. by means of two vibrators. For many products is a compression by a percussion - z. B. by pounding - recommended. For some products, such as As the above-mentioned sandwich stone with elastic polystyrene, however, a shake is better suited as Verdichtungsart. Also, shaking is more suitable for compacting concrete moldings with large cavities, such as. As rings and chimney rings. However, while earlier manufacturing devices available on the market either provided shaking or pounding, the most preferred embodiment of the concrete molding manufacturing apparatus as a combination machine may optionally be both at one station. An excellent shake and compaction of the concrete moldings can be achieved if the shake directly compresses the concrete molding without an intermediate production range.

Furthermore, according to a particularly preferred embodiment of the concrete molding production device, a settling flexibility can be achieved. In the case of commercially available manufacturing devices, either a vertical offset or a flat shelf was possible. The advantageous embodiment of Betonformlingherstellvorrichtung allows a combined deposition, where either either a vertical offset or a flat shelf is possible. For beginners, there is the possibility, with a To begin more cost-effective edge reduction, and later add the flat-laying portion of the filing system later. A flat shelf is recommended for thinner and / or to be ground or polished goods.

According to a preferred embodiment of the invention, a plant flexibility can be achieved, resulting in three additional options. According to a preferred embodiment of the invention, the Betonformlingherstellvorrichtung can be connected to existing edgewise circuits and still be discharged flat for certain orders. Conversely, a preferred embodiment of the Betonformlingherstellvorrichtung can be integrated into an existing flat shelf and at the same time produce edgewise, if the manufactured concrete moldings for the flat storage system are too thick. If one looks at the cycle of a stone production plant, the new concrete molding production apparatus according to a preferred embodiment can represent an alternative (in exchange) or a supplement (additionally in circulation) due to its multifunctionality. A supplement can be imagined, for example, in such a way that the concrete molding manufacturing apparatus in question, if the premises permit, is installed on the dry side and is always used when the brick maker is overwhelmed; z. B. in large formats, in domestic products, with the desired design from above and from below, with the finest surfaces, such. B. a concrete molding with natural sandstone optics, the desired design flexibility through different structures in plates, high-strength products, sharp edges, reinforcement inserts, coarse washed concrete, etc.

It is also a color flexibility possible, for example, the Betonformlingherstellvorrichtung can be combined with multicolor, for example, two- or three-color intent mixing systems.

Advantageous are the short set-up times and mold costs. Due to the multifunctionality of the mold, the set-up costs are considerably reduced, since often a mold change is eliminated. The costs also fall because the mold has an extremely long life over many years and only the wear parts have to be changed. In conjunction with a low cement requirement, a low dry cleaning time and a high end product strength (inter alia made possible by a particularly good compaction), the particularly preferred embodiment of the Betonformlingherstellvorrichtung allows high quality of the final product at low running costs.

For example, set-up times of less than 30 minutes for molds and compaction changes, and less than 1 minute for a multi-function change in height, design, or product itself within the multifunction mold or in terms of loading and unloading, etc., can be achieved.

Low cycle times of 15 to 20 seconds are possible.

In a concrete embodiment, format sizes of products in length, width and height of up to 1200 × 600 × 215 mm are possible; optional format sizes of 800 × 800 × 200 are possible. Of course these are only examples.

Next, a modular design is possible. For example, a vending machine with a turner can be used to turn the products 90 ° for a vertical offset or a turner with a possible turn of the products 180 ° for a flat shelf or a reversible turner 90 ° for a flat shelf or a vertical shelf become. Furthermore, a flat storage system including an automatic traverser and an automatic storage and retrieval system can be integrated. Further, the concrete molding manufacturing apparatus can be connected to a block molding machine cycle. Furthermore, packaging can be integrated with a packaging machine, heavy packaging or a package converter with integrated vertical strapping. Further, known finishing equipment could be integrated which fabricates structures by means of dies, washing, blasting, grinding and / or polishing, brushing, coating, impregnating, splitting or the like.

Thus, with the preferred embodiment of the Betonformlingherstellvorrichtung a very wide, high-quality range of different concrete molding end products with high differentiation potential with low production costs can be achieved.

Accordingly, the Betonformlingherstellvorrichtung is attractive for investment in existing concrete works or for beginners in stripped-down level.

For existing paving and slab works, a machine constructed in accordance with the teachings described herein is an attractive alternative to existing systems or, due to its compact design, can be additionally integrated into existing circuits.

More preferably, the concrete molding manufacturing apparatus is configured such that it can be easily converted into a turntable machine having a plurality of stations. This can increase the performance by two times.

In the illustrated case, the silos 61 . 62 over silo trolleys 64 movable, but they can also be stationary each at a fixed position. By means of these silos 61 . 62 become the stuffing car 70 . 72 filled.

In the example shown, there is a first filling car 70 that is between the first silo 61 and the shape 14 back and forth and a second filling car 72 that is between the second silo 62 and the shape 14 back and forth. Thus, there is always a separate filling car 70 . 72 for facing concrete and core concrete. You fill with the silo 61 . 62 , the bottom of the flap 65 has, the respective filling car 70 . 72 , The filling car 70 . 72 fills the mold 14 , He is driven to the front and drives back again. The order of filling can be set arbitrarily. For example, the filling can be done by holding the header down and refilling the core concrete. According to another type of procedure works with only one material, so z. B. only with the intent. Or you can do it the other way round, filling first the core concrete and then the intent. There is still the possibility that one fills the intent first, then - z. B. manually or via a reinforcement insertion machine, not shown - inserts a reinforcing grid and then refilled.

That would be a so-called three-layer process. The reinforcement grid can be inserted manually or automatically. There is still the possibility that you pull the intent by 90 °. You can therefore fill the header and pulls the intent, after the filling process is completed, manually upward so that you have the intent not only on one side, but also on one of the side surfaces.

After the concrete is filled, there are two different compression methods. Either it is shaken - this sits the vibrator or the Rüttelwerk 42 at the vibrating table 28 - or you compress from above with the stamping plant 36 ,

The shaker is at the vibrating table 28 represented and is at the base - here on the stand 40 , The stamping plant 36 is located above the vibrating table 28 and has up and down moving tools.

The stamping plant 36 applies during the shaking function as a load, ie during jogging is exerted from above pressure.

One can therefore on the one hand the Stampfwerk 36 hold rigid and then shake from below. Or you can the Rüttelwerk 42 hold rigid and then stamp from above. Thus, at a single station both pounding and shaking is possible. The concrete molding manufacturing device 10 thus allows at one point filling with a first type of concrete, filling with a second type of concrete, pounding or shaking or pounding and shaking and settling. To settle points the increase 46 , which can also be referred to as Schabotte or anvil, the openings 52 or holes in order to eject the concrete moldings afterwards and settle can.

If different products are produced, the appropriate shape 14 replaced. It can be simple forms, as in the 5 - 9 or four-fold or double-mold or eight-fold, etc. When pounding a symmetrical assignment of ramming tools is advantageous. At the bottom of the mold is the so-called die (not shown) which forms the lower mold. This is interchangeable. This gives you the design flexibility. In particular, you can achieve the shape with the bottom down. The die can then be passed over the ejection unit 50 emit.

The concrete molding manufacturing device 10 can be combined with different sales techniques, which are not shown in detail in the drawings. On the one hand, it is possible to push the products off the die with a smooth die. On the other hand, it is also possible to move the products together with the die. Next, the products with the die can be pivoted together, in which case the die z. B. is pivoted back over a magnet or other holding device, so that then the products are free.

Instead of the illustrated rigid form 14 can also be a form with mutually movable side walls (not shown) are provided. A movable side wall may thus form a side molding device for molding designs or structures on the side of the concrete moldings. In this case, the concrete molding maker is 10 additionally provided with a lateral Formeinrichtungsbewegungseinrichtung for lateral displacement of the lateral shaping device, for example by means of a third hydraulic unit.
