The concrete dividers are moved across or diagonally to each point above the concrete brick mold (4) which are completely or partially filled with concrete of different colors after a prescribed program. An independent claim is also included for an installation of making concrete bricks. Preferred Features: A program is prescribed to color a concrete brick so that a brick set is produced with an ornamental brick structure.

Description

The invention relates to a method for producing differently colored concrete block products such as concrete paving stones, concrete slabs, split blocks and the like, also with special attachments, as well as wet-cast products on a plant for concrete block production with a machine frame, a mold holder, a concrete block mold, a ballast, a vibrating table with vibrators and a concrete block form acting distributor device for carrying out the method.

The time of the monotonous traffic routes, garden landscapes, terraces and driveways, equipped with gray concrete slabs and gray cobblestones, is long gone. Colored concrete products were discovered as design elements, whereby now laying patterns as well as colored stones were used and with a maximizing effect the combination of both design variants. It can be so, for example, Lay pebbles quarter-half and full circles, as well as fan-shaped patterns can be achieved. The colored concrete paving stones are produced by the addition of colored pigments in fresh concrete or by facing concrete made of natural minerals.

Increasingly, however, now the laying patterns are determined by applying a variety of different colored concrete paving stones or concrete slabs in an image, sometimes with an ornamental character. This, an aesthetic cityscape forming installation pattern but in terms of production in both the manufacturing process and in terms of cost limits, namely in the production of different colored concrete elements always a time-dependent conversion of mixers, concrete pavers and possibly with different stone structure and the exchange of another Concrete block shape with other stone configurations is required, especially if only a small batch is required to form a complex installation pattern of a particular type of stone.

The invention is based on the object, the production and installation costs for colored and room-structured concrete elements, even from the perspective of a greater variety, to optimize economically and to make installation images with new color compositions.

This is achieved in that a concrete distributor device is equipped with several by a special kinematics independently movable concrete distributors and a core concrete distributor and these, individually or electronically programmatically, one after the other longitudinally, transversely or diagonally precisely to each point on the concrete block mold can be moved and Thus, the concrete block form can be filled entirely or partially according to a predetermined program with concretes of different colors and logically concrete block elements can be produced in different colors. In this way, the laying patterns of concrete paving stones and concrete slabs can now be refined in a variety of shapes and colors, with both production and installation being considerably more cost-effective than the state of the art.

According to an essential feature of the invention, when the target coordinates are reached, the scales are opened via metering slides, and a predetermined amount of concrete is introduced into the containers Cast stone form omitted, the number of breakpoints is freely programmable. In this way, the pattern in its diversity is almost unlimited and roughly comparable to the patterning of textiles, so that one can then offer, for example, catalog-structured, varied laying patterns to the customer in sales talks.

According to a further feature of the invention, there is a fundamental alternative in the production of the concrete block elements, namely to produce them as solid blocks of colored concrete or to design only one facing layer in color. This depends mainly on their intended use, ie at high load as a full color stone and more decorative

Use and reduced load with colored attachment layer.

After a ausgestaltenden feature of the invention, different color compositions can be selected from stone to stone set set or even the stone elements within a single manufacturing set are designed differently color. Thanks to this innovative technology, the road builder and the garden architect have plenty of room to maneuver, so he can offer a wide range of Stein + design; In this way, paths, terraces, driveways and squares can, of course, be adapted to suit the respective environment.

According to a further development of the invention, segments of a single concrete slab can be made different in color. With these color differences to be created in a very small space, the creative scope is extended to a mosaic, opening up an artistic area that can lead to ornamentation even after a widening characteristic.

Other design possibilities result from sharp delimitation of the colors at the edges of the concrete elements or by fluent transitions at the edges.

A particularly important feature of the invention results from the application of a fluorescent or phosphorizing material on the surface of the concrete blocks and in a further safety-relevant extension, the production of fluorescent or phosphorizing concrete blocks is associated with the production of natural or colored stones in a single manufacturing set, whereby such by the arrangement of the stone types in the offset special laying pattern for z. B. noctilucent road crossings for pedestrians and cyclists can be generated. In particular, this would prevent accidents, benefit old people, the disabled and children.

The inventive method underlying plant for concrete block production is characterized in that a concrete paver is bordered by a stationary frame with rails, in which provided with wheels, scales having, over the concrete block form movable Farbbetonverteiler and a core concrete distributor are arranged, either from a in x and y direction movable linear drive or an industrial robot can be retracted over any point of the concrete block mold, wherein the concrete manifolds are acted upon by a filling and dosing unit consisting of intermediate bins with stirrers, a metering screw with a mixer shaft and a device for mixing Preparation and dosing water, the production cycle in a known manner by the delivery of a color-provided dry mix from dern central mixer in a central silo on a treadmill and from there into an intermediate bunker is initiated with spiked roller.
As described hereinbefore, the inventive method is machine-implemented by means of a standard, commercial concrete paver bordering, the distribution elements receiving, fixed frame, the smallest possible space is achieved by the tight enclosure, and secured during maintenance optimal access from all sides to the machine is.

But what also distinguishes the high efficiency of the inventive method, is the fact that usually in the prior art to produce a range of different colored and / or different in their structure and structure concrete blocks, possibly still in a tight time window , several concrete pavers would have to be used, where machine investment, staff requirements and land area would have to be expected.

In a special embodiment of the distribution modes, a servo drive with toothed belt transmission is provided for driving a concrete distributor, wherein the individual concrete distributors are retractable via a 2.Linearantrieb both in the x-axis and in the y-axis accurately to any point on the concrete block shape or as a variant that is provided as an actuator and control element for the filling with their 4 concrete distributors, an industrial robot and arranged so that the filling device is rotatable by 360 °.

Such an efficient production and function of the inventive concrete block paver is ensured with known, sometimes commercially available mechanical components.

Further details can be taken from the claims and the specific description.

The inventive method is in accordance with its realization Fig. 9 a machine plant, which consists essentially of a concrete block paver 1 commercially available type and a surrounding this special concrete distribution device. The concrete block maker 1 essentially has a machine frame 2, a vibrating table 3 with vibrators, a concrete block mold 4, a load 5 and a Formhubeinrichtung 6. New are the necessary for the realization of the inventive method erforderlischen elements for filling the concrete block mold 4. Solcherart the concrete paver 1 is surrounded by a stationary frame 22 with rails 23 in which provided with wheels 24, scales 36 having , on the concrete block mold 4 movable concrete distributor 21/1, 21/2; 21/3 and 21/4 are arranged, as well as in a clear way the Fig. 8 can be seen.

In a central mixer 7, a gravel-sand-cement granules dosed entered, possibly also slightly added water, and prepared as a dry mix. Under the central mixer 7, a centering silo 11 is arranged, at the lower opening of a conveyor belt 8 connects, which promotes a provided with a spiked roller 10 intermediate bunker 9, which feeds the concrete into a metering screw 12 and a mixer shaft 27 provided with agitators 20 Interposed bunker 19, which in turn enters the concrete in the equipped with balances 36 concrete distributors 21, - see also Fig. 8 - It is apparent from the fact that the system in longitudinal and transverse rails running, different colored concrete containing concrete distributor 21/1, 21/2, 21/3 and 21/4, as well as a core concrete distributor 25th

A water inlet 15 acts on an additive container 14 with a flushing valve, from where the mixture into a container 17 with agitator 28 with a water mixture condenser and further into a device 13 for mixing water treatment, below which a frequency-controlled pump 18 is arranged, which promotes via a flow meter 26 and nozzles 29 in the mixer shaft 27.
The water mixture is discharged via a spirit level in the intermediate bunker 19 with about 400 liters of capacity, with an empty request or full report via electrical control probes.

In the central dosing and mixing plant 7 with a max. Capacity of 1 m concrete is metered as usual and premixed without addition of water with dry paint (granules). Via a transport system, the dry mixture is unloaded into the corresponding concrete bunker 19, wherein for each color F1 F2; F3 and F4 an intermediate bunker 19/1; 19/2; 19/3 and 19/4 with wet mixer is provided. A probe in the support wall of the mixer measures the moisture in the concrete. Via a downstream control, the frequency-controlled pump 18 is turned on, i. if the concrete moisture is too dry, the speed increases, if too wet, the same slows down. A dosage of mixing water is mixed via a dosing with additive and stored in a container 13. Each wet mixer 19/1; 19/2; 19/3 and 19/4 with agitator 20 is supplied via a water metering, consisting of a frequency-controlled water pump 18 with a flow regulator 26 and downstream nozzles 29 with mixing water. The wet mixing plant consists of an intermediate bunker 9 with spiked roller 10, metering screw 12 and mixer shaft 25, wherein the mixing process continuously via the intermediate bunker 19/1; 19/2; 3.19; and 19/4, which have a full request and empty message installed at their top. When contact "request", positioned shortly before the empty message, run dosing belt 12, mixer worm 25 and water pump 18 at. The drive dosing belt and mixer worm is constant, while the water is added via the frequency-controlled pump 18. The mixing water is controlled by the pump 18 and the flow regulator 26. Also, the intermediate bunker 19 with the agitators 20 have a display "full request and empty" on. With "empty" or "request", the agitator 20 starts in the intermediate bunker 19 and mixes continuously until "full" message takes place. During the filling and in the waiting times, the concrete is slowly kept in motion by means of the agitator in order to prevent sedimentation of the concrete.

For the filling of the concrete block mold 4 are 4 color concrete distributors 21/1, 21/2, 21/3 and 21/4 and 1 core concrete distributor 27 are available, so for each colored concrete and the core concrete one each. The concrete distributors 21 can be moved in all directions by means of a linear drive 31, wherein, for example, a servo drive with toothed belt transmission is used. can. The individual concrete distributors can be linearly moved linearly over each point of the concrete block mold 4 via a second drive both in the x-axis and in the y-axis. When the target coordinates are reached, the balance 36 opens via a metering slide 37 and discharges a predetermined amount of concrete into the concrete block mold 4. The number of breakpoints is freely programmable for each distributor with scale. The different types of concrete (colors) can thus be precisely placed one above the other or side by side in the concrete block mold 4.

A variant in the filling of the concrete block mold 4 is achieved via the installation of an industrial robot 32, on whose middle support 33 a filler 34 with 4 containers 35/1; 35/2; 35/3; 35/4 is mounted, wherein the filler device 34 is rotatably mounted by 360 ° on a balance 36. In function, the robot 32 travels with him arranged containers 35/1; 35/2; 35/3; 35/4 the intermediate bunker 19/1; 19/2; 19/3 and 19/4, wherein the containers receive a predetermined amount of the different colored concretes. For filling the concrete block mold (4), the robot 32 pivots the filler device 34 with its individual containers 35/1; 35/2; 35/3; 35/4 on the shape and there programmatically a predetermined type of concrete (color) and quantity in the form, the number of breakpoints and the amount of concrete are freely programmable.
The different types of concrete can thus be precisely placed one above the other, side by side or even during the process of the filler 34 in the concrete block mold 4.
