Description

The invention relates to a device for producing concrete elements using a filling mold.

The invention also relates to an arrangement for producing concrete elements from a liquid or pasty building material, in particular a concrete mixture. The invention further relates to a method for producing concrete elements using a filling mold.

The production of concrete slabs and/or terrace slabs known from the prior art generally deals with the most precise possible dosage of such a building material, in particular with such a dosage of concrete and further in particular with an exact dosage of at least the facing concrete. Likewise, for certain areas of application of the concrete slabs and/or terrace slabs, it may sometimes be necessary to dose a liquid or pasty building material of a second type onto the liquid or pasty building material of a first type.

A liquid or pasty building material of a first type is a first layer and/or layer which is filled into corresponding filling molds, with, if necessary, in a second step a liquid or pasty building material of a second type and/or thus a second layer is applied to the liquid or pasty building material of the first type, so that in the installed state, for example, only the hardened building material of the second type is visible to the user. If only the liquid or pasty building material of the first type is filled into the filling molds, of course only this is visible to the user.

However, previous methods for dosing such a building material are not only cost-intensive, but also difficult to implement. Above all, appropriate cleaning after using an appropriate device for dosing the liquid or pasty building material can only be carried out with great difficulty.

This is due, among other things, to the fact that in order to clean a corresponding device, the device usually only has to be cleaned with a high-pressure cleaner, since the solidified or semi-solidified building material can often only be removed from the device in this way. The water jet applied under high pressure can blast away hardened concrete residues from the machine.

However, the respective cleaner of the device is exposed to large streams of dirt (consisting of water and building material) after and during cleaning. In other words, such a cleaner is very dirty after cleaning such a device.

The system consists of a concrete delivery pump and a spray head equipped with a flow distribution valve. The flow distribution valve includes a valve body forming an internal control cavity, a rotary valve member rotatably disposed in the internal control cavity, a spray head outlet port, a supply port, and a circulating outlet port. The spray head outlet port, the feed port and the circulating outlet port are disposed on the valve body and communicate with the control internal cavity.

US 5,340,512 A shows an apparatus and method for producing an improved electrical insulator from a polymer-based concrete composition. The device provides for the formation of the mixture, the components of which are combined in a mixer. The mixture is degassed using a vacuum. A mold is filled with the degassed mixture.

DE 33 27 415 A1 shows a method and a device for applying mortar in the production of prefabricated brick panels. The mortar is applied using a mortar application device that can be moved in a horizontal plane over the course of blocks. A mortar nozzle of a nozzle chamber is used, and a pump line is connected to the mortar nozzle and to the mortar storage container for returning the mortar. The mortar nozzle has a closure part to close it and a connection that releases the mortar conveying element.

DE 10 2010 053 520 A1 discloses a device for loading molds for producing concrete slabs or concrete blocks. The concrete mixture is located in at least one filling pocket, which can be moved over at least one mold by a controllable or regulatable drive for filling the respective mold. A loading unit is used to convey the concrete mixture into the at least one filling pocket. Furthermore, a device is provided for the controlled or regulated delivery of the concrete mix to the transporter.

DE 10 2004 059 954 A1 relates to a device for metering the filling quantity for filling into molds for the production of building blocks. The device is arranged between a storage container, for example for liquid concrete, and the forms to be filled. Dosing sockets, which can be filled at one end by the storage container and can dispense their contents to the molds at the other end, are provided in the device. The internal volume of the metering bushings can be changed mechanically, pneumatically or hydraulically. In particular, changing the dosing quantity is also made more difficult by the fact that in order to change a dosing quantity, the respective device has to be cleaned using a high-pressure cleaner, so that an exchange of the metering bushings of the device is only possible after such cleaning.

DE 10 2019 111 432 A1 discloses a device and a method for producing concrete elements, according to the preamble of claim 1 or claim 13, more particularly, this document discloses a method for metering a liquid or pasty building material, in particular a concrete mixture, by providing and starting up a pump device. The pump device pumps the liquid or pasty building material out of a reservoir so that the building material is transported towards a distribution element.

CH 424 594 A relates to a method for the serial production of prefabricated concrete parts in formwork batteries and a device for carrying out this procedure. Using a piston pump or screw conveyor, the concrete mortar is filled from below through a pipe into spaces formed by formwork for hardening, one after the other.

Another problem in the current state of the art is the distribution of the building material on a rubber matrix, since the building material is sometimes very sticky and the addition of water to clean this rubber matrix is often limited.

The transport device has at least one positioning means for guiding the colored fresh concrete from the metering chambers into the concrete bunker. The positioning means can place different colored portions of fresh concrete at predeterminable positions in the concrete bunker.

DE 20 2015 003 366 U1 discloses a device for filling cavities of a building material or component, in particular a building block, with a foam material. The device includes a reservoir (container) for material to be filled. Several openings in the reservoir lead via lines to a filling element which has several filling ports. Each line running between the openings of the reservoir and the filling element has a pump in the form of a piston, rotary piston, gear, sine or hose pump. In the case of piston pumps, the open ends of the piston cylinders can be connected in successive steps either to the reservoir and to the filling element via a common translationally displaceable plate-shaped switch element.

The invention is based on the object of creating a device for producing concrete elements by means of a filling mold, which can be operated in a particularly simple and cost-effective manner, makes cleaning the device easier and faster, shortens the set-up times of the device and at the same time enables the precise and rapid dosing of a liquid or pasty building material into the corresponding filling forms.

This object is achieved by a device for producing concrete elements using a filling mold, which comprises the features of claim 1.

A further object of the invention is to create an arrangement for producing concrete elements from a liquid or pasty building material, in particular a concrete mixture, which continuously and cost-effectively produces concrete slabs of one type and reduces the set-up time for converting the arrangement to a punch-based type of concrete slabs reduced.

This object is achieved by an arrangement for producing concrete elements from a liquid or pasty building material, which comprises the features of claim 8.

Another object of the invention is to create a method for producing concrete elements using filling molds, which method can be carried out in a particularly simple and cost-effective manner and facilitates the precise and rapid dosing of the respective liquid or pasty building material into the corresponding molds.

This object is achieved by a method for producing concrete elements from a liquid or pasty building material, the method comprising the features of claim 13.

According to the invention, the device for producing concrete elements by means of a filling mold comprises a reservoir for a liquid or pasty building material and a pump unit, which has at least one piston pump, for filling the liquid or pasty building material (building material of a first type). The at least one piston pump is connected to the reservoir via at least a first tubular connection (fluid). The device comprises at least one doser, which is connected to the at least one piston pump via a second tubular connection (fluid). The at least one piston pump supplies the liquid or pasty building material (building material of a first type) to the at least one metering device via the second tubular connection. A control device is communicatively connected at least to the at least one piston pump and an operating device, optionally also to a transport unit which moves the filling molds along a transport direction. A mechanical device of the device serves to at least position and hold an opening of the at least one doser relative to the filling mold.

The advantage of the device according to the invention for producing concrete elements or concrete slabs is that a defined and controlled filling of the filling molds with the liquid or pasty building material as building material of a first type is possible. The device for filling the filling molds with the building material of the first type can be designed cost-effectively. Cleaning the device can be carried out inexpensively and easily. The setup time of the device can also be shortened.

In addition, the dosage of the building material of the first type into the filling molds can be precisely adjusted so that the respective filling form is completely filled, for example, with the building material of the first type (concrete slabs then consist, for example, of one layer of the building material of the first type). first type). When the filling process of the filling molds with the building material of the first type is completed, it is sufficient for the at least one piston pump to be switched off. Due to the lack of pump pressure, no building material emerges from the opening of the at least one doser.

According to at least one embodiment, the at least one piston pump is a multiple cylinder pump, in particular a double cylinder pump.

According to one embodiment, the mechanical device of the device is connected to the at least one doser. This makes it possible to move the opening of the at least one doser in a horizontal direction, a transport direction and/or a vertical direction relative to the filling mold, in particular on the transport unit, or to position the opening of the at least one doser statically above the filling mold.

The advantage of the mechanical device is that the opening of the at least one dosing device can be moved at least in the horizontal direction and in the transport direction, which thus ensures uniform distribution and faster filling of the filling mold with the building material of the first type.

According to a preferred embodiment, at least the second tubular connection of the device is designed to be movable and elastically deformable. In the context of the invention, “tubular connection” means any hose element between each piston pump and the corresponding doser. The hose element can also be a static, permanently installed pipeline. Alternatively, the hose element can also be a plastic, in particular a rubber hose, which is flexible and elastic.

“Flexible” in this context means that the hose element is designed and intended to be bent without the hose element suffering structural damage, for example cracks.

The hose element or the second tubular connection therefore has at least two openings. A first opening is with the at least one piston pump or the intermediate one Distribution element connected, into which the liquid or pasty building material is pumped by the at least one piston pump and thus pressed. The other opening of the hose element (second opening) is the opening from which the liquid or pasty building material enters the at least one doser. To control the flow of the liquid or pasty building material from the reservoir to the pump unit and/or from the pump unit to at least one metering device, according to the invention an operable slide mechanism is assigned to the reservoir, which can be actuated, for example, by motor, pneumatically or hydraulically. The slide mechanism serves to regulate the inflow of the liquid or pasty building material into the first tubular connection or the second tubular connection. The slide mechanism is assigned to the reservoir in such a way that, controlled by the control device, either a connection of the reservoir to the first tubular connection and thus to the pump unit or a connection from the pump unit via the second tubular connection to the doser can be released or closed.

In one embodiment, the motor-, pneumatically or hydraulically actuated slide mechanism comprises a first closure and a second closure. Depending on the operating position of the slide mechanism, the first closure blocks (or releases) the inflow of the pasty building material from the reservoir to the pump unit with the at least one piston pump. The second closure blocks (or releases) the inflow of the pasty building material from the pump unit with the at least one piston pump into the second tubular or hose-like connection.

According to a further embodiment, the control device is designed such that the at least one piston pump of the pump unit is able to generate different pump pressure levels. The slide mechanism can be actuated in coordination with the operating mode of the at least one piston pump of the pump unit.

The advantage is that the pump unit is able to generate pumping pressures of different pumping pressure levels by means of the control device. The at least one piston pump of the pump unit can be controlled individually by the control device. For example, a pump pressure can be increased gradually during the procedure or is actually increased gradually. In this respect, it is possible for the pump unit to carry out a pressure increase and/or a pressure reduction during a filling process of a filling mold or during the filling process between the individual filling molds, that is, while the pump unit sets the pump pressure of the at least one piston pump to zero.

According to a further aspect, an arrangement for producing concrete elements from a liquid or pasty building material is provided. The liquid or pasty building material can in particular be a concrete mixture. The arrangement includes at least one device for placing the liquid or pasty building material of a first type into filling molds. In addition, a transport unit is provided which moves the filling molds along a transport direction.

The device can be used to completely or partially fill the filling molds. The filling mode depends on the type of concrete slab to be made with the arrangement. For concrete slabs that only consist of one layer, the device is used to completely fill the filling form with the liquid or pasty building material of the first type.

According to one embodiment of the arrangement, a station is provided for placing the liquid or pasty building material of a second type into the filling molds. This is the case when concrete slabs are produced which consist of the building material of the first type and the building material of the second type. Here the filling form is then not completely filled with the pasty building material of the first type, and at the station the liquid or pasty building material of the second type is then filled onto the building material of the first type in order to fill the filling form. The transport unit of the arrangement can be linear or circular.

In one embodiment, the filling forms used in the arrangement consist of at least a circumferential frame and a base. Furthermore, the filling forms can be provided with at least one division.

The transport unit of the arrangement can also be controlled with the control device.

The method for producing concrete elements using filling molds is characterized in that filling molds are moved along a transport direction by means of a transport unit and fed to a device for filling a liquid or pasty building material of a first type. The filling forms are positioned under an opening of at least one doser for a predefined period of time by a control device. The opening is stationary relative to the filling molds or a relative movement can take place between the at least one doser and the respective filling mold. By means of a pump unit, which comprises at least one piston pump, the liquid or pasty building material is transported from a reservoir along a second tubular connection to the at least one doser, controlled by the control device. The liquid or pasty building material is transferred from the opening into the filling form. With a mechanical device controlled by the control device, the opening of the at least one doser is held above the respective filling form. A slide mechanism, which is assigned to the first tubular connection and the second tubular connection, controls so that, under the control of the control device, either a connection of the reservoir to the first tubular connection or a connection from the pump unit via the second tubular connection to the at least one dosing device is released or is closed.

According to one embodiment of the method, the filling mold can be fed to a station if the filling mold is not completely filled with the liquid or pasty building material of the first type. At the station, the liquid or pasty building material of a second type is poured from a pouring opening onto the liquid or pasty building material of the first type that is already in the filling mold. Finally, the liquid or pasty building material of the second type is smoothed in the filling mold using a smoothing device.

According to one embodiment of the method, the mechanical device moves the at least one dosing device in the horizontal direction, in the transport direction and in the vertical direction relative to the filling mold during the filling process.

The liquid or pasty building material of the second type is not always necessary. Since, as already described, there are also terrace slabs that are only made from... liquid or pasty building material of the first type. There are therefore concrete slabs or terrace slabs that consist of two layers and concrete slabs or terrace slabs that consist of one layer. The concrete slabs or terrace slabs made of one layer are more common in southern regions.

The advantage of the method according to the invention is that concrete elements (slabs) can be produced quickly and cost-effectively.

It is conceivable that a filling mold is initially filled using a first filling pressure and then using a second filling pressure. The first filling pressure can be a lower pressure value than the second filling pressure. However, a third, fourth, fifth, etc. filling pressure is also possible, which filling pressures either become larger or smaller, or change between a higher and/or a lower filling pressure between the individual filling pressures. It is conceivable that the first filling pressure is higher than the second filling pressure, while the second filling pressure is in turn lower than the third filling pressure. For example, the third filling pressure can be identical to a first filling pressure. In this respect, the filling process of a single filling device and/or several filling devices is generated in the form of a sawtooth-shaped filling pressure curve (against a time axis).

As already briefly explained above, during the filling of a single filling mold, this filling mold can be filled using two, three or more filling pressures, and / or a filling mold is filled with only a single filling pressure. For example, each filling form can be assigned a specific filling pressure, preferably a single filling pressure, with which the filling form is filled.

According to at least one embodiment, a plurality of filling molds, in particular arranged in a matrix in relation to one another, are at least partially filled, preferably one after the other, by means of the arrangement according to the invention in conjunction with the device.

“Matrix-shaped” in this context means an arrangement of the filling molds in a plane perpendicular to a filling direction (preferably in a direction parallel to the direction of gravity) in the form of rows and columns, so that the filling molds are preferably arranged equidistant from one another along these rows and columns.

For example, the filling forms are filling forms of the same or different volume.

According to at least one embodiment, filling of the filling mold or filling molds is carried out semi-automatically or fully automatically using the arrangement. The filling molds are moved one after the other into the filling position of the device of the arrangement for the building material of the first type and are thus successively completely or partially filled with the building material of the first type. The control device monitors and controls the process and filling of the filling molds.

According to at least one embodiment, the operating device is a filling robot which fully automatically fills the filling mold or molds on the device and the subsequent station, if present, of the arrangement.

The filling robot can therefore be a fully automatically operated robot which, once switched on and operated and/or regulated by the above-mentioned control unit, carries out a filling process from start to finish (building material of the first type or building material of the first type and Building material of the second type) without any further help. It is conceivable that the filling process is only ended after the last filling form to be filled has been completed and the filling robot then returns to a rest position.

According to at least one embodiment, the pump unit has at least two, for example four or more, individual piston pumps, with a second hose element leading from each piston pump to a metering device. According to a possible embodiment, the number of metering devices can be analogous to the number of piston pumps present in the pump unit. According to another possible embodiment, it may also be that there is a different one Number of dosers and piston pumps. For example, eight metering devices and four piston pumps can be provided. The dosers with the openings are detected by a mechanical device (arm of the operating device). Before filling (filling in the building material of the first type), the opening of the respective dosing device (can also be such a hose element or a hose element assigned to this filling form) is then positioned over each filling form. Various filling forms are then filled with the building material of the first type at the same time or one after the other and then removed. The majority of the openings can therefore be connected in parallel to one another, which can mean that each of the openings from which the building material of the first type emerges is, for example, simultaneously held above the respective filling forms.

In this context, it is conceivable that a robot arm of the operating device simultaneously grips the majority of the dosing devices with their openings. For example, the dosers are attached to a common holder with their openings. The robot arm then fixes all dosing devices simultaneously over the corresponding filling forms, so that these corresponding filling forms can be filled with building material of the first type in one filling process. However, it should be noted that not only two or four filling forms can be filled with building material of the first type at the same time, but any number of filling forms can also be filled with building material of the first type in one filling process.

According to at least one embodiment, the opening of the doser or the respective openings of the dosers are at least temporarily fixed during the filling process with the building material of the first type and thus remain immovable, while by means of a control device after each completed filling process with the building material of the first type Openings of the dosers another filling form that is still unfilled is moved.

The control device described here can be the control device already described at the beginning or a further control device.

In other words, in such an embodiment, instead of moving the openings of the dispensers relative to the fixed device, the filling molds are moved. Such a movement of the filling molds, but also a movement of the dispensers themselves, can take place in the form of a revolver-like rotation.

According to one embodiment of the device, the pump unit is a concrete pump. The concrete pump can be a multiple cylinder pump, in particular a double cylinder pump. By means of the control device, an output of the facing concrete can also be supplied to the openings of the metering devices in a controlled and/or regulated manner.

According to at least one embodiment of the device, the control device is set up and intended to control and/or regulate a supply of the liquid or pasty building material of the first type to the doser or dosers in such a way that the piston pump or the piston pumps, preferably only, within a predetermined pumping time window, the liquid or pasty building material of the first type is pumped into the doser or dosers and outside this pumping time window a reduced amount, but preferably essentially no, building material is pumped into the doser or dosers.

According to at least one embodiment of the device, the pumping time window is a period of at least three seconds and at most 30 seconds, preferably at least five seconds and at most 15 seconds.

With reference to the accompanying drawings, the invention and its advantages will now be explained in more detail using exemplary embodiments, without thereby limiting the invention to the exemplary embodiment shown. The proportions in the figures do not always correspond to the real proportions, as some shapes are simplified and other shapes are shown enlarged in relation to other elements for better illustration.

The device 1 comprises a pump unit 10, which pumps out a liquid or pasty building material 6 from a reservoir 2 . The pump unit 10 includes at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N . The at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N of the pump unit 10 is connected to the reservoir 2 via a first hose element 3 ₁ or a first tubular connection 3 ₁ . With the at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N , the liquid or pasty building material 6 can be fed along a second hose element 3 ₂ or a second tubular connection 3 ₂ to at least one metering device 5 ₁ , 5 ₂ , ... , 5 _N can be transported or pumped. The liquid or pasty building material 6 is preferably transported solely by means of the pump pressure generated by the at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N of the pump unit 10 . Due to the pump pressure generated by the at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N of the pump unit 10 , the building material 6 emerges from an opening 31 of the at least one metering device 5 ₁ , 5 ₂ , ..., 5 _N with a Exit pressure is greater than zero and is thus brought into a filling mold 7 via the at least one opening 31 during the filling process.

For the filling process, the opening 31 of the at least one dosing device 5 ₁ , 5 ₂ , ..., 5 _N is held above the filling mold 7 . In the embodiment shown here, the at least one filling mold 7 is located on a transport unit 8, so that the filling mold 7 is, for example, at a position opposite the opening 31 of the at least one dosing device 5 ₁ , 5 ₂ , ..., 5 _N. In addition to the movement through the transport unit 8, the at least one doser 5 ₁ , 5 ₂ , ..., 5 _N can also be moved to the opening 31 of the at least one doser 5 ₁ , 5 ₂ , ..., 5 _N above the Position filling form 7 .

A control device 20 for the device 1 is connected at least to the at least one piston pump 11 ₁ , 11 ₂ , ..., 11 _N via a control line 21 .

By means of the mechanical device 24, the at least one dosing device 5 ₁ , 5 ₂ , ..., 5 _N can be held above the opening 31 during filling over the filling mold 7, with the respective filling taking place fully automatically in the present exemplary embodiment. Likewise, the opening 31 of the at least one dosing device 5 ₁ , 5 ₂ , ..., 5 _N can be held one after the other over selected filling forms 7, in particular over each of the filling forms 7, or into one by means of the mechanical device 24 in conjunction with the control device 20 Filling position can be brought in relation to the filling molds 7 .

The movement of the opening 31 of the at least one doser 5 ₁ , 5 ₂ , ..., 5 _N can take place in the horizontal direction H, transport direction T and/or vertical direction V , so that optimal, uniform and time-saving filling of the filling molds 7 is achieved .

Figure 2 shows a top view of the embodiment of the device 1 according to Fig. 1 . In this embodiment of the device 1, the pump unit 10 consists of four individual piston pumps 11 ₁ , 11 ₂ , 11 ₃ and 11 ₄ , each of which is individually connected to the second hose element 3 ₂ or the second tubular connection 3 ₂ , each with one of the four metering devices 5 ₁ , 5 ₂ , 5 ₃ and 5 ₄ is connected.

By means of the control 22 , the four dosing devices 5 ₁ , 5 ₂ , 5 ₃ and 5 ₄ and thus their respective opening 31 can be positioned above the filling molds 7 via the mechanical device 24 or can be moved during the filling process of the filling molds 7 or relative to the filling molds. With the mechanical device 24 , the four dosers 5 ₁ , 5 ₂ , 5 ₃ and 5 ₄ can individually realize different movement patterns, in groups different movement patterns or all together realize the same movement pattern. In order to enable the movement of the four dosers 5 ₁ , 5 ₂ , 5 ₃ and 5 ₄ , at least the second tubular connection 3 ₂ is designed to be movable and elastically deformable.

For the purpose of describing the invention, this includes: Fig. 2 illustrated embodiment is equipped with four dosers 5 ₁ , 5 ₂ , 5 ₃ and 5 ₄ and the four individual piston pumps 11 ₁ , 11 ₂ , 11 ₄ and 11 ₄ , each of which has a doser 5 ₁ , 5 ₂ , 5 ₃ or 5 ₄ is assigned. It's for a professional It goes without saying that the number of metering devices 5 ₁ , 5 ₂ , ..., 5 _N and the individual piston pumps 11 ₁ , 11 ₂ , ..., 11 _N as well as their combination or assignment cannot be viewed as a limitation of the invention.

Figure 3 shows a top view of a further embodiment of the device 1. In this embodiment of the device 1 , the pump unit 10 consists of two individual piston pumps 11 ₁ and 11 ₂ , each of which is individually connected to a respective second hose element 3 ₂ or second tubular connection 3 ₂ respectively one of the two dosers 5 ₁ and 5 ₂ is connected.

Figure 4 shows a top view of yet another embodiment of the device 1. In this embodiment of the device 1 , the pump unit 10 consists of a single piston pump 11 ₁ , which is connected to the second hose element 3 ₂ or the second tubular connection 3 ₂ to the doser 5 ₁ .

It is obvious to a person skilled in the art that the arrangement and the number of divisions 72 or divisions 72 can be made depending on the customer's wishes and therefore do not represent a limitation of the invention.

The ones in the Figures 9A and 9B The different views shown show an embodiment of an arrangement 1000 for the production of concrete elements 100. For the production of concrete elements 100, which consist of a layer of the building material 6 of the first type 102 and a layer of the building material 6 of the second type 101 , the arrangement 1000 comprises at least one Device 1 according to the invention (for introducing the building material 6 of the first type 102 into the filling mold 7 ) and at least one station 200 (for introducing the building material 6 of the second type 101 into the filling form 7 ). With the device 1 and the station 200 , in addition to a pre-press, a pressing station, a distribution station and an ejection station (not shown here), the concrete elements 100 constructed from the building material 6 of the second type 101 and the building material 6 of the first type 102 can be produced . In the same way, concrete elements 100 can also be produced with the arrangement, which consist only of the building material 6 of the first type 102 .

Figure 9A shows a top view of the schematically illustrated arrangement 1000 and Figure 7B shows a side view of the schematically illustrated arrangement 1000. Filling molds 7 for the concrete elements 100 to be produced are transported on a transport unit 8 along a transport direction T. The filling molds 7 first reach the device 1 according to the invention in the transport direction T , with which the building material 6 of the first type 102 is filled into the filling molds 7 . At another station 200 following in the transport direction T , building material 6 of the second type 101 is filled into the filling form 7 on top of the building material 6 of the first type 102 , since in this embodiment the filling form 7 is not completely filled with the building material 6 of the first type 102 is. The following description serves only to describe the invention and should not be construed as a limitation.

In order to fill the filling molds 7, in the embodiment shown here, a device 1 is arranged in front of a station 200 in the transport direction T.

To introduce the building material of the first type 102 into the filling mold 7, the device 1 according to the invention has two dosers 5 ₁ and 5 ₂ , each with an opening 31 . To fill the filling molds 7 with the building material of the first type 102 , the filling molds 7 are always located under the openings 31 of the two dosing devices 5 ₁ and 5 ₂ shown here. In order to distribute the building material of the first type 102 in the filling mold 7 , for example a vibrating unit 103 and/or a press (not shown) can be provided, which attacks the filling form 7 containing the building material of the first type 102 , in order to thus create the building material of the first type 102 First type 102 to be distributed fairly evenly in the filling mold 7 . When the filling process of the respective filling form 7 with the building material of the first type 102 is completed, the piston pumps 11 ₁ and 11 ₂ assigned to the two dosers 5 ₁ and 5 ₂ (not shown in FIGS. 1A and 7B) are switched off. Due to the lack of pump pressure, no more building material of the first type 102 emerges from the openings 31 .

The filling mold 7 then arrives with the building material of the first type 102 at the station 200, at which the building material of the second type 101 is introduced into the filling mold 7 on top of the building material of the first type 102 . The building material of the second type 101 passes from the pouring opening 32 of the station 200 into the respective filling mold 7. After the filling mold 7 with the filled building material of the second type 101 has left the station 100 , for example with a smoothing device 35, such as a slide, the building material of the second type 101 is smoothed in the filling form 7 . After hardening, the plate 100 or the plates 100 can be removed from the filling mold 7 .
