[0003] SYSTEM FOR THE MANUFACTURING OF CONCRETE PRODUCTS BY CASTING, COMPLETING A STORAGE RACK

[0004] Description

[0005] The present disclosure relates to an at least partially automated system for producing concrete products, in particular hollow concrete products or tubular concrete products such as concrete pipes and / or manhole bases and other precast concrete elements, by means of a casting process using preferably vertical molds having at least one outer shape.

[0006] background

[0007] Semi-automated plants and systems for manufacturing concrete products, in particular manhole bases and / or concrete pipes, are known in the prior art. The semi-automated production of the concrete products is typically carried out using a vibratory compaction process or a rotary compaction process, in which the compaction and internal shaping of the concrete products is achieved by means of a roller head.

[0008] However, manufacturing systems for producing tubular concrete products using vibratory compaction or rotary pressing are expensive and require a large footprint, as they necessitate complex and space-consuming vibratory compaction or rotary pressing equipment, as well as a large product storage area and ample space for additional socket and mold storage. Furthermore, complex changeover procedures are required when manufacturing products of different sizes.

[0009] Furthermore, it is known to produce individual, high-quality tubular concrete products using a casting process in a stationary formwork. However, due to the longer curing times required for concrete, it is significantly more difficult to provide an automated production system in which tubular concrete products can be manufactured automatically using a cost-effective and high-quality casting process.

[0012] In this context, prior art has proposed automated systems for the production of tubular concrete products, in particular concrete pipes, in which concrete products are transported in a circulation system between individual workstations of a production area by means of a form conveyor device and are produced in a casting process in an at least partially automated production cycle, controlled by program and clocked.

[0013] A generic system is described, for example, in DE 10 2012 217 324 A1, wherein the system comprises a manufacturing area with a plurality of automated workstations and a mold conveying device for conveying the casting molds or the outer mold and the mold core (as an exemplary inner mold) of casting molds between the workstations.

[0014] The production area of ​​the system described in DE 10 2012 217 324 A comprises a demolding station for removing an outer mold from a casting mold positioned at the demolding station and for removing a hardened tubular concrete product from a mold core positioned at the demolding station. Furthermore, the production area comprises a cleaning station for cleaning a mold core positioned at the cleaning station and for cleaning an outer mold positioned at the at least one cleaning station, a mold assembly station for assembling a casting mold from an outer mold and a mold core, and a filling station for filling an assembled casting mold with concrete.

[0015] Another generic system is described, for example, in DE 10 2016 202 411 A1. This system also includes one or more manually operated mold setup devices with at least one mold setup station for manually assisted assembly of a casting mold from corresponding outer and inner molds.

[0016] Another system of this type is described, for example, in DE 10 2022 133 700 Al. This system also includes a socket installation station for mounting or inserting a socket onto a casting mold.

[0069] Detailed description of the figures and preferred embodiments of the invention

[0070] Preferred, purely exemplary embodiments are described in detail below with reference to the accompanying figures. However, the present disclosure is not limited to the described embodiments. Identical or similar features of the embodiments are identified in the figures by the same reference numerals. Unless differences are explicitly stated or apparent from the figures, it is to be assumed that a description of features with the same reference numerals applies to one embodiment as well as to another, and the description is not repeated for the sake of brevity.Furthermore, the exemplary embodiments are not to be considered self-limiting, since it is possible to combine features of the exemplary embodiments described below or to modify exemplary embodiments with features of other exemplary embodiments in order to obtain further exemplary embodiments. Such modifications or combinations of features are to be regarded, at least implicitly, as part of the disclosure of this description.

[0071] In general, all molds used in the system according to the exemplary embodiments have at least one outer mold and, optionally, one or more inner molds (e.g., mold cores, channel molds, etc.) that can be positioned and / or are positioned within the outer mold. Molds can be provided for various concrete products, e.g., molds for concrete pipes and / or molds for manhole bases, etc. For example...

[0072] P10443PC Johann Schlüsselbauer - 10 - December 4, 2025

[0073] Ulrich Schlüsselbauer's molds, operating in a (preferably at least partially automated) cycle, can each have a stationary outer mold and, optionally, a mold core (as an example of an inner mold) arranged within the stationary outer mold (possibly vertically). Similarly, molds set up automatically, semi-automatically, and / or manually can have an outer mold and, optionally, one or more inner molds that can be positioned within and / or are positioned within the outer mold. Outer and / or inner molds can be designed in one or more parts. The design of the outer and / or inner molds can be tailored to the desired shape of the concrete body or precast concrete element (concrete product) to be produced. For example, one or more inner molds for the production of concrete pipes can have one or more essentially cylindrical mold cores.One or more internal molds for the production of shaft bases can, for example, include channel molds for a channel of the respective shaft base, which can be introduced at any setup stations.

[0074] In some embodiments, vertical molds can be used into which, after semi-automated, fully automated, or manual setup at respective setup stations and / or in respective setup areas, preferably flowable, self-compacting concrete is poured using a casting process at one or more filling devices in a filling area of ​​the circulation system, for example, at workstations designed as respective filling stations. This allows the circulation system in embodiments to dispense with any vibrating devices and instead provide a curing area in which the concrete-filled molds can be stored for a longer period until the concrete has hardened and / or the molds are ready for demolding or removal.The hardened concrete product can be removed and / or reintroduced into the production area of ​​the preferably at least partially automated circulation system for subsequent reuse. Circulation system within the meaning of this disclosure thus means that the molds used in the system can be re-set up and refilled with concrete after demolding (i.e., in particular after the removal of at least partially hardened concrete products).

[0075] Optionally, the (or at least some of the) molds can also have, for example, a base sleeve on the underside, which serves, for example, as a standing surface for setting up the molds and / or for locking the outer mold to an inner mold (e.g.

[0076] P10443PC Johann Schlüsselbauer - 11 - December 4, 2025

[0077] Ulrich Schlüsselbauer (a mold core). Such lower sleeves can be removable or permanently attached to the inner mold or the inner mold core. Likewise, in exemplary embodiments, the (or at least some of the) casting molds can be closed from above with upper sleeves after being filled with concrete. In these embodiments, respective (preferably at least partially automated) workstations for applying upper sleeves can be provided, at which upper sleeves can be placed (preferably semi- or fully automatically) on or attached to casting molds already filled with concrete.

[0078] In particular, it can be advantageous that, in some embodiments, the system can produce a wide variety of concrete products of different types, shapes, and / or sizes within the same system (see, for example, the various exemplary concrete products on the mold conveying section 250 in Fig. 7A). For this purpose, different molds of various types, shapes, and / or sizes can be present simultaneously in the circulation system, with the workstations designed as setup stations preferably enabling the setup process for different concrete products depending on the product.

[0079] Depending on the requirements of the specific concrete product, additional mold components and / or reinforcement or reinforcement cages can be installed in some of the prepared molds. Besides reinforcement or reinforcement cages, other structural components that remain in or on the finished concrete product can also be attached to some molds, for example, to install climbing aids or stirrups, or transport anchors that remain in the product. For special concrete products, this can also include other embedded components such as valves for livestock troughs or frames and / or grates for road drains. This can be implemented at the respective workstations of the system, which are designed as setup stations, for example, semi-automatically and partially manually, or even with one or more manually performed setup steps.

[0080] Fig. 1 shows a schematic top view of a system for producing concrete products by casting, using exemplary vertical molds, according to some embodiments. The system for producing concrete products by casting according to Fig. 1 includes, by way of example, an automated (i.e.,

[0081] P10443PC Johann Schlüsselbauer - 12 - December 4, 2025

[0082] Ulrich Schlüsselbauer semi-automated or fully automated and possibly preferably program-controlled) cycle in which casting molds are used in circulation to manufacture concrete products.

[0083] The exemplary system according to Fig. 1 comprises a curing and / or storage area I for storing molds, including molds filled with concrete during the curing of the concrete after the respective mold has been filled with concrete, and / or for the temporary storage of molds. The exemplary system according to Fig. 1 comprises a production area, for example, comprising a setup area for preparing molds before filling with concrete (e.g., setup area II in Fig. 1), a filling area for filling prepared molds with concrete (e.g., filling area III in Fig. 1), and a demolding area for demolding molds (e.g., demolding area I in Fig. 1).

[0084] In this embodiment and the embodiments described below, a multi-level storage area is provided in one or more rack storage units within storage and / or curing area I. In some preferred embodiments, one or more multi-level storage structures can thus be provided within curing area I, designed for the multi-level storage of molds and / or concrete products curing within a mold. In some particularly advantageous embodiments, such multi-level storage units can comprise one or more high-bay racks.In this context, one or more transport systems, for example with one or more storage and retrieval machines, can be configured to place casting molds semi-automatically and / or fully automatically at storage locations 310 in the multi-story storage structures and / or to pick them up semi-automatically and / or fully automatically at storage locations 301 in the multi-story storage structures. Additional manipulators can be provided for this purpose.

[0085] By way of example, the curing and / or storage area I according to Fig. 1 is provided by a rack storage system 300, and in particular, by way of example, by a high-bay storage system in some preferred embodiments. In particular, the rack storage system 300 provides, by way of example, a plurality of storage locations 301 on several storage levels, especially for storing casting molds filled with concrete in a circulating cycle, which can cure the concrete preferably without vibration in a stationary position for an extended period of time. In addition, if desired, already prepared casting molds can be stored in storage locations 301 of the rack storage system 300 before the

[0086] P10443PC Johann Schlüsselbauer - 13 - December 4, 2025

[0087] Ulrich Schlüsselbauer

[0088] Filling with concrete can be temporarily stored, and / or currently unused casting molds can be temporarily stored until further use.

[0089] The exemplary rack storage system 300 of the system according to Fig. 1 comprises, by way of example, a first high-bay rack 320-1 and a second high-bay rack 320-2 and a transport device 310 (e.g., a mobile storage and retrieval machine or a transport device comprising a mobile storage and retrieval machine), which is arranged, by way of example, in an aisle extending in the longitudinal direction X of the rack storage system 300 between the first high-bay rack 320-1 and the second high-bay rack 320-2. The first high-bay rack 320-1 comprises, by way of example, several rack levels arranged one above the other, each rack level having, by way of example, a plurality of storage locations 301 arranged in a row in the longitudinal direction X of the high-bay rack 320-1. The second high-bay rack 320-2 similarly comprises, by way of example, several rack levels arranged one above the other, each rack level having, by way of example, a plurality of storage locations 301 arranged in a row in the longitudinal direction X of the high-bay rack 320-2.

[0090] By way of example, the high-bay racks 320-1 and 320-2 are arranged parallel in the longitudinal direction X, wherein the transport device 310 is, by way of example, horizontally movable between the high-bay racks 320-1 and 320-2 in the common longitudinal direction X of the high-bay racks 320-1 and 320-2. In preferred embodiments, the transport device 310 comprises a storage and retrieval machine with three movable axes.

[0091] In preferred embodiments, the transport device 310 can comprise a storage and retrieval machine equipped with at least three movable axes. The movement of the storage and retrieval machine can take place in the following three axes: X = longitudinal aisle direction (e.g., a travel unit, which may optionally preferably be rail-guided, or a travel unit that moves freely on the factory or hall floor at least in the X direction), Z = vertical direction (e.g., a lifting unit, for example, comprising a telescopically vertically movable lifting device), and Y = transverse aisle direction (e.g., with a horizontally transversely movable load handling unit).

[0092] In particular, the transport device 310 between the high-bay racks 320-1 and 320-2 in the common longitudinal direction X of the high-bay racks 320-1 and 320-2 is exemplified as being between a first transfer position P2 for the demolding area IV at one end of the rack storage 300 and a second transfer position P3 for the filling area III at one

[0093] P10443PC Johann Schlüsselbauer - 14 - December 4, 2025

[0094] Ulrich Schlüsselbauer can move the other end of the rack storage 300 on the side opposite in the longitudinal direction X.

[0095] Furthermore, the transport device 310 can be equipped, for example, with a handling device, e.g., to remove and / or place molds at storage locations 301 in the high-bay racks 320-1 and / or 320-2 on the various rack levels. In some embodiments, the various rack levels (e.g., stacked one above the other in the Z-direction) can, starting from a base level shown in plan view in Fig. 1 (e.g., a ground-level floor, such as a warehouse floor HB according to Fig. 7B), comprise one or more rack levels arranged above the base level with respective storage locations 301 (see, e.g., also Fig. 7B). Alternatively or additionally, the rack levels can also comprise one or more rack levels arranged below the base level with respective storage locations 301 (see, e.g., also Fig. 7B).

[0096] In some particularly advantageous embodiments, the rack storage system or the racks of the rack storage system can be designed with several shelf levels of different heights, so that, for example, smaller molds with a low height can be stored on a lower shelf level and / or, for example, larger molds with a greater height can be stored on a shelf level with a greater height in order to provide an optimized storage capacity in relation to the total height of the rack storage system (see, for example, also Fig. 7B).

[0097] The system according to Fig. 1 further includes, by way of example, an at least partially automated mold conveying system with mold conveying sections 210a and 210b, 220a and 220b, and 230a and 230b for conveying molds within the system, in particular between the various areas of the production area and the rack storage 300. The production area includes, by way of example, a plurality of stations, comprising, by way of example, several workstations 110 or 120 for demolding or setting up molds and, by way of example, several workstations 130 provided as filling stations.

[0098] In some preferred embodiments, the mold conveying sections of the mold conveying device and / or the workstations of the system can be controlled or operated in a synchronized manner according to a common cycle time. Alternatively, it is also possible to control different areas of the system, for example, a demolding area, a

[0099] P10443PC Johann Schlüsselbauer - 15 - December 4, 2025

[0100] Ulrich Schlüsselbauer

[0101] The setup area and / or a filling area can be operated independently of each other or with different cycle times.

[0102] In embodiments in which the forming conveying sections of the forming conveying device and / or the workstations of the system are controlled or operated according to a common clock cycle, the transport device 310 of the rack storage 310 is preferably configured to be controlled or operated independently of the clock cycle of the system.In particular, the transport device 310 may preferably be configured to perform several work operations during one cycle of the system, including work operations such as picking up a mold at a transfer position and placing the mold at a storage location in the rack storage system, picking up a mold at a storage location in the rack storage system and placing the mold at a transfer position, picking up the mold at one transfer position and placing the mold at another transfer position, and / or picking up a mold at one storage location in the rack storage system and placing the mold at another storage location in the rack storage system.

[0103] In some embodiments, the transport device 310 is preferably configured to transport molds with different accelerations and / or transport speeds, particularly preferably depending on the working state of the mold (i.e., depending on whether an empty mold without concrete and without at least partially hardened concrete product, a prepared mold, a demolded mold, a mold just filled with liquid concrete, and / or a mold with a partially hardened concrete product is being transported). In particular, the transport device 310 is preferably configured to transport molds just filled with liquid concrete with a lower acceleration and / or a lower maximum speed than when transporting empty molds (e.g.,The transport device 310 can alternatively or additionally be configured to transport molds containing a concrete product that has already hardened at least partially with a higher acceleration and / or a higher maximum speed than when transporting empty molds (e.g., molds that have been set up and / or demolded) and / or molds that have just been filled with liquid concrete.

[0106] Molds.

[0107] The exemplary mold conveying device according to Fig. 1 comprises several mold conveying sections 210a to 230b, each configured to transport molds at least in a horizontal direction. In Fig. 1, the respective mold conveying sections 210a to 230b are shown as straight lines. In some further embodiments, angled and / or curved mold conveying sections can alternatively or additionally be provided.

[0108] One or more of the mold conveying sections 210a to 230b can preferably be configured to convey upright molds, particularly preferably automatically, e.g. on movable carriages, movable tables or transfer tables, vehicles, conveyor belts, etc. Furthermore, one or more mold conveying sections can alternatively or additionally be provided by means of movable lifting devices and / or crane devices in order to lift the molds and transport them in a lifted state (for example, analogous to the transport device 410 for product discharge described below).

[0113] The exemplary filling area III of the system according to Fig. 1 comprises, by way of example, several workstations 130 designed as filling stations. In particular, the filling stations 130 are configured to fill a casting mold positioned at the respective filling station 130 with concrete, either semi-automatically or preferably automatically. In some embodiments, only one filling station 130 can be provided at a time, whereas in preferred embodiments, several are provided as filling stations 130, so that several casting molds can advantageously be filled with concrete efficiently at the same time (e.g., at two filling stations 130 in Fig. 1).

[0114] The exemplary demolding area IV of the system according to Fig. 1 comprises, by way of example, several workstations 110 designed as demolding stations. In particular, the workstations 110 are configured, by way of example, so that molds can be demolded automatically, semi-automatically (i.e., manually assisted), and / or manually at the respective workstations 110. Demolding within the meaning of the disclosure here refers in particular to the removal of at least partially hardened concrete parts from the respective molds. In particular, demolding can include opening the mold or the outer mold of the mold and / or, in particular, removing the at least partially hardened concrete product from the mold, for example, by vertically pulling the concrete product off the opened mold or from an inner mold of the mold.In some embodiments, at least one such workstation 110 designed as a demolding station can be provided, wherein in preferred embodiments several workstations 110 designed as demolding stations are provided, so that several molds can be efficiently demolded simultaneously (e.g. at two demolding stations 110 in Fig. 1).

[0115] Furthermore, the system according to Fig. 1 optionally includes an additional transport device 410, which is configured to transport concrete parts or concrete products removed from the demolding station(s) 110 to an output position P6. Optionally, the system also includes a form conveying section 250 for conveying finished concrete products from the

[0117] Ulrich Schlüsselbauer

[0118] Output position P6 along the form conveying section 250, for example for the intermediate storage of several already completed concrete products before they are finally removed from the system (see, for example, Fig. 7A).

[0119] The transport device 410 can, in some embodiments, be configured as a further mold conveying section. In some particularly preferred embodiments, the transport device 410, as shown by way of example in Fig. 1, can comprise a handling device with a lifting function, movable on guides 420, which is configured to lift at least partially hardened concrete products from at least partially opened molds at the demolding stations 110 and transport them by moving them along the guides 420 to the output position P6 and deposit them there. Such a handling device can, for example, also include a gripper device, which can, for example, also be configured to rotate or pivot concrete products removed from a mold, particularly preferably to, if necessary,To rotate or swivel standing cast concrete products before placing them at the output position P6, for example to swivel them into a lying position.

[0120] The storage and / or curing area I according to Fig. 1 includes, by way of example, the semi- and / or fully automated transport device 310, wherein the transport device 310 is configured, by way of example, to transport casting molds from transfer positions P2 and P3 to storage positions or storage locations 301 in the rack storage system 300 and from storage positions or storage locations 301 in the rack storage system 300 to the transfer positions P2 and P3. By way of example, the transport device 310 is arranged between two rows of racks 320-1 and 320-2 of the rack storage system 300, wherein the transfer positions P2 and P3 are, by way of example, arranged at opposite ends of the rack storage system 300 in the longitudinal direction X.By way of example, the racking rows are designed as high-bay racks 320-1 and 320-2 extending in the longitudinal direction X, wherein the transport device 310 is arranged to be movable in the longitudinal direction X in an aisle formed between the high-bay racks 320-1 and 320-2, in particular to move in the aisle in the longitudinal direction X between the transfer positions P2 and P3 of the racking system 300.

[0121] For example, the transport device 310 is configured to move to the transfer position P2 of the rack storage 300 and to transfer the goods at the transfer position P2 of the

[0122] P10443PC Johann Schlüsselbauer - 19 - December 4, 2025

[0123] Ulrich Schlüsselbauer

[0124] In the rack storage area 300, a casting mold is to be picked up or placed at a transfer position Pia or Plb of the mold conveying sections 210a or 210b of the demolding area IV. The mold conveying sections 210a and 210b of the demolding area IV are configured, for example, to transport a casting mold between the respective transfer position Pia or Plb and a respective workstation 110 designed as a demolding station.

[0125] For example, a casting mold with a concrete product that has already hardened at least partially can be picked up from the transport device 310 at a corresponding storage location 301 of the rack storage 300 for demolding and transported to the transfer position P2 of the rack storage 300 in order to be placed at the transfer position Pia or Plb of the demolding area IV and transported with the corresponding mold conveying section 210a or 210b to the corresponding demolding station 110.

[0126] Furthermore, a mold demolded at a demolding station 110 can be transported by the corresponding mold conveyor section 210a or 210b to the corresponding transfer position Pia or Plb of the mold conveyor sections 210a or 210b of demolding area IV, in order to be picked up there by the transport device 310 positioned at the transfer position P2 of the rack storage 300. From there, the demolded mold can be transported by the transport device 310 to a storage location 301 for temporary storage or placed by the transport device 310 at a transfer position P5a or P5b in order to be fed directly to setup area II via the corresponding transfer positions P5a or P5b (see below).

[0127] As an example, the transport device 310 is configured to move to the transfer position P3 of the rack storage system 300 and to pick up or place a mold at transfer position P4a or P4b of the mold conveying sections 230a or 230b of filling area III. The mold conveying sections 230a and 230b of filling area III are configured, as an example, to transport a mold between the respective transfer position P4a or P4b and a respective workstation 130 configured as a filling station.

[0128] P10443PC Johann Schlüsselbauer - 20 - December 4, 2025

[0129] Ulrich Schlüsselbauer

[0130] For example, a prepared mold for the casting process can be picked up by the transport device 310 at a corresponding storage location 301 of the rack storage 300 or directly after setup at a transfer position P5a or P5b and transported to the transfer position P3 in order to be placed at the transfer position P4a or P4b and transported with the corresponding mold conveying section 230a or 230b to the corresponding filling station 130.

[0131] Furthermore, a casting mold filled with concrete at a filling station 130 can be transported by the corresponding mold conveying section 230a or 230b to the corresponding transfer position P4a or P4b, in order to be picked up there by the transport device 310 positioned at the transfer position P3. From there, the concrete-filled casting mold can be transported by the transport device 310 to a storage location 301 of the rack storage system 300 for curing (or also for temporary storage before optionally closing the casting mold with a top sleeve).

[0132] In some embodiments, in addition to the transfer positions P2 (with Pla / Plb) and P3 (with P4a / P4b) arranged at the ends of the shelf aisle opposite each other in the longitudinal direction X between the shelves 320-1 and 320-2, further lateral transfer positions P5a and P5b are preferably provided at shelf locations of the shelf 320-1 on the base level, wherein these transfer positions P5a and P5b at the shelf locations of the shelf 320-1 are connected to the transversely (i.e. in the transverse direction Y) extending mold conveying sections 220a and 220b, wherein the mold conveying sections 220a and 220b are configured to transport the molds deposited by the transport device 310 at the transfer positions P5a and P5b at the shelf locations of the shelf 320-1 out of the shelf storage 320 in the transverse direction Y. The molds can, for example, be passed through the shelf 320-1 in the transverse direction Y at the transfer positions P5a and P5b at the shelf locations of shelf 320-1.This makes it advantageous to provide three or more processing areas that can be loaded separately from the rack storage in a compact and space-saving design, whereby one or more processing areas can be arranged laterally (in the transverse direction Y) next to the rack storage.

[0133] The following is a brief example of how a concrete product can be manufactured using the system shown in Fig. 1. Figs. 2A to 2J illustrate some exemplary intermediate stages in the production of a concrete product using the system.

[0134] P10443PC Johann Schlüsselbauer - 21 - December 4, 2025

[0135] Ulrich Schlüsselbauer according to Fig. 1 circumferential casting mold G.

[0136] A mold G for the production of the corresponding concrete product can either already be temporarily stored at a storage location 301 of the rack storage 300 and picked up there by the transport device 310 of the rack storage 300, or after demolding in connection with a previously produced concrete product, be picked up by the transport device 310 at the transfer position P2 (see e.g. Fig. 2A with the mold G at the transfer position Plb and the transport device 310 at the transfer position P2).

[0137] For the setup process, the transport device 310 can place the mold G at a transfer position P5a or P5b in the aisle of the high-bay warehouse 320-1 on the base or working level of the storage rack 300 (see, for example, Fig. 2B with the mold G at the transfer position P5b and the transport device 310 next to the transfer position P5b), in order to be transported from there laterally to the corresponding setup station 120, transverse to the longitudinal direction of the storage rack 300, by means of the corresponding conveyor section 220a or 220b (see, for example, Fig. 2C with the mold G transported to the corresponding setup station 120 via the conveyor section 220b).

[0138] At the corresponding setup station 120, the mold G can optionally be cleaned and / or optionally oiled. In particular, the mold G can be set up at setup station 120 manually, with manual assistance, at least partially automatically, or fully automatically. A set-up mold, as defined in the disclosure, means a mold that is prepared for feeding to the filling station. In the simplest case, this can mean that an outer part of the mold is closed. In preferred cases, simple setup operations can be carried out fully automatically at setup station 120. For more complex setup operations, this can also be carried out partially automatically and / or with manual assistance. In some cases, it may also be provided that one or more steps of the setup operation, or even the entire setup operation, are carried out manually at setup station 120.

[0139] After setting up the mold G at the corresponding setup station 120 (see e.g. Fig. 2C with mold G at the corresponding setup station 120), the set up mold G can be moved with the corresponding mold conveying section 220a or 220b to the corresponding

[0140] P10443PC Johann Schlüsselbauer - 22 - December 4, 2025

[0141] Ulrich Schlüsselbauer

[0142] The prepared mold G can then be transported to transfer position P5a or P5b to be picked up by the transport device 310 of the rack storage system 320. The prepared mold G can then be transported either to a storage location 301 of the rack storage system 320 for temporary storage or directly to transfer position P3 of the rack storage system 320 for transfer to one of the transfer positions P4a or P4b of filling area III for a subsequent filling (pouring) operation (see, for example, Fig. 2D with the transport device 310 carrying the mold G at transfer position P3).

[0143] For the filling process, the prepared casting mold G, which can be retrieved from either a storage location 301 or from one of the transfer positions P5a or P5b by the transport device 310, is transported by the transport device 310 to the transfer position P3 of the rack storage 300 (see e.g. Fig. 2D), in order to be placed there by the transport device 310 at one of the transfer positions P4a or P4b and transported via the corresponding conveyor section 203a or 230b to the corresponding filling station 130 and to be filled with concrete at the filling station 130 during the casting process (see e.g. Fig. 2E with casting mold G filled with concrete at a filling station 130).

[0144] After the filling process, the concrete-filled casting mold G can be transported with the corresponding mold conveying section 230a or 230b from the corresponding filling station 130 to the corresponding transfer position P4a or P4b, in order to be picked up by the transport device 310 at the transfer position P3 and transported to a storage location 301 of the rack storage 300 for the curing process (see e.g. Fig. 2F with the casting mold at a storage location 301 of the storage rack 320-2).

[0145] If the concrete in the casting mold G stored at storage location 301 has at least partially hardened after the curing time, the casting mold G can be picked up by the transport device 310 and transported to the transfer position P2 of the rack storage 300, in order to be placed at one of the mold conveying sections 210a or 210b at the corresponding transfer position Pia or Plb and transported from the corresponding mold conveying section 210a or 210b to the corresponding demolding station 110 (see e.g. Fig. 2G with casting mold G positioned at a demolding station 110).

[0146] P10443PC Johann Schlüsselbauer - 23 - December 4, 2025

[0147] Ulrich Schlüsselbauer

[0148] At the demolding station 110, the mold G can be at least partially opened (see, for example, Fig. 2G with the mold G partially opened), and the transport device 410 can lift the at least partially hardened concrete product out of the at least partially opened mold G and transport it to the output position P6, where it is placed (see, for example, Fig. 21 with the concrete product P placed at the output position P6). The demolded mold G can then be transported again via a corresponding conveyor section 210a or 210b to the corresponding transfer position Pia or Plb in the storage rack 300 (see, for example, Fig. 2J analogous to Fig. 2A). Fig. 2J also shows, by way of example, that the concrete product P can be temporarily stored on the conveyor section 250 for collection, so that the output position P6 is free again for another finished concrete product.

[0149] Fig. 3 shows an exemplary schematic top view of a system for producing concrete products by casting according to some further embodiments.

[0150] In contrast to the embodiment shown in Fig. 1, here, on both sides of the rack storage unit 320 in the transverse direction Y, a first setup area 11-1 (analogous to setup area II in Fig. 1) and a second setup area 11-2 opposite in the Y direction are provided next to the rack 320-2 of the rack storage unit 300. The second setup area 11-2 includes, by way of example, two further setup stations 120 and corresponding forming conveyor sections 220c and 220d with corresponding transfer positions P5c and P5d at storage locations of the rack 320-2 on the base level. This can also be provided additionally in the other embodiments, in particular, for example, in systems according to Figs. 4 and 5.

[0151] The additional lateral transfer positions P5c and P5d are provided as examples at shelf locations of the rack 320-2 on the base level, wherein these transfer positions P5c and P5d at the shelf locations of the rack 320-2 are connected to the transverse (i.e., in the transverse direction Y) mold conveying sections 220c and 220d, wherein the mold conveying sections 220c and 220d are configured to transport the molds deposited by the transport device 310 at the transfer positions P5c and P5d at the shelf locations of the rack 320-2 out of the rack storage in the transverse direction Y. The molds can, for example, be conveyed at the transfer positions P5c and P5d at the shelf locations of the rack 320-2 in the transverse direction Y through the rack 320-2 into the

[0152] P10443PC Johann Schlüsselbauer - 24 - December 4, 2025

[0153] Ulrich Schlüsselbauer

[0154] Preparation area 11-2 will be passed through.

[0155] Furthermore, in the system according to Fig. 3, two transport devices 310a and 310b are provided, by way of example, in the aisle or lane between the racks 320-1 and 320-2 of the rack storage system 300. This can also be provided additionally in the other embodiments, in particular, for example, in systems according to Figs. 4 to 7B. The first transport device 310a can, by way of example, be configured to place or pick up molds at transfer position P3 or at transfer positions P4a or P4b, and the second transport device 310b can, by way of example, be configured to place or pick up molds at transfer position P2 or at transfer positions Pia or Plb. By way of example, both transport devices 310a and 310b can serve or reach several or all transfer positions P5a to P5d and / or all storage locations 301 in the rack storage system 300.

[0156] Fig. 4 shows an exemplary schematic top view of a system for producing concrete products by casting according to some further embodiments.

[0157] In contrast to the embodiment shown in Fig. 1, optional additional workstations 140 are provided in the demolding area IV. For example, one additional workstation 140 is provided for each demolding station 110, each arranged on the side of the respective demolding station 110 opposite the storage rack 300 and connected to the corresponding demolding station 110 via a respective mold conveyor section 240a or 240b, which is configured to transport a mold from the demolding station 110 to the corresponding additional workstation 140 and back. This can also be provided additionally in the other embodiments, particularly, for example, in systems according to Figs. 3 and 5.

[0158] The workstations 140 can perform one or more optional additional tasks or functions, preferably manually, manually assisted, semi-automatically, and / or fully automatically. For example, an advantageous function of workstation 140 could include inserting new molds at the respective workstation 140, preparing new molds before inserting them into the circulation system at the respective workstation 140, and / or removing molds that are no longer needed from the system at the respective workstation 140.

[0159] P10443PC Johann Schlüsselbauer - 25 - December 4, 2025

[0160] Ulrich Schlüsselbauer

[0161] Circulation system.

[0162] Alternatively or additionally, this can include the inspection or maintenance of molds at the corresponding workstation 140, for example, before they are returned to the circulation system after demolding. Alternatively or additionally, this can include the cleaning and / or oiling of molds at the corresponding workstation 140 before they are returned to the circulation system after demolding.

[0163] Furthermore, this can alternatively or additionally include the partially or fully automated opening and / or complete opening of molds at the corresponding workstation 140 before the removal of a concrete product at the demolding station 110. Furthermore, this can alternatively or additionally include the inspection of concrete products in the respective opened molds at the corresponding workstation 140 before the removal of the concrete product at the demolding station 110, for example, any leak tests. In particularly suitable versions, this can alternatively or additionally include the manually assisted or manual removal of any mold components, auxiliary parts, and / or accessories from the mold and / or the addition of any components (e.g.,Seals) on the concrete product before demolding, for example, before a hardened concrete product is removed from the transport device 410 at demolding station 110 by a gripper and / or lifting device. For example, at workstation 140, any inserts or recesses can be removed from the opened mold if necessary. Workstation 140 can also include a device for removing optional top sleeves.

[0164] Fig. 5 shows an exemplary schematic top view of a system for producing concrete products by casting according to some further embodiments.

[0165] In contrast to the embodiment shown in Fig. 1, here the filling stations 130 in filling area III are operated by a common filling device 510, wherein the filling device 510 can be moved between the filling positions of the filling stations 130, for example, via guides 510. For example, the filling device 510 can be moved to the filling position of one of the filling stations 130 in order to fill a mold arranged at this filling station 130 with concrete, and then the filling device 510 can be moved to the filling position

[0166] P10443PC Johann Schlüsselbauer - 26 - December 4, 2025

[0167] Ulrich Schlüsselbauer can be moved to another filling station 130 to fill a casting mold arranged at this other filling station 130 with concrete, etc. This can also be additionally provided in the other embodiments, in particular, for example, in systems according to Figs. 2 to 4. The filling device 510 can include a pouring device, for example, with a pouring bucket.

[0168] The filling unit can advantageously serve multiple filling stations at a higher frequency, thus allowing the next concrete product to be poured at a different filling position without waiting times, or at least with significantly reduced waiting times. This results in advantageously short standing times for the mixed concrete before pouring. This prevents potential segregation of aggregates in the concrete and / or premature hardening of the concrete at the filling unit, thereby improving the prevention of potential system malfunctions. In some embodiments, the filling unit 510 can be fed via a mixing plant and / or an optional conveying system, e.g., a bucket conveyor.

[0169] Fig. 6 shows an exemplary schematic top view of a system for producing concrete products by casting according to some further embodiments.

[0170] In this case, the exemplary system according to Fig. 6 combines, in an exemplary, particularly compact and efficient arrangement, further features of the systems according to Fig. 3 (i.e., optionally two lateral working areas 11-1 and 11-2 in Fig. 6), Fig. 4 (i.e., optionally additional work stations 140 in the demolding area IV) and Fig. 5 (i.e., optionally a movable filling device 510 for two or more or preferably all filling stations 130 in the filling area III).

[0171] For example, the rack storage system 300 comprises four rows or shelves extending in the longitudinal direction X, each of which can be designed as pairs of shelves with an aisle in between and an associated transport device (preferably with a corresponding storage and retrieval machine) analogous to the above embodiments.

[0172] Analogous to Fig. 1, the system in the rack storage facility 300 comprises the two racks 320-1 and 320-

[0173] 2 with transport device 311 arranged in between (analogous to transport device 310)

[0174] P10443PC Johann Schlüsselbauer - 27 - December 4, 2025

[0175] Ulrich Schlüsselbauer and additionally another parallel double rack running in longitudinal direction X with racks 330-1 and 330-2 with a transport device 312 arranged between them. The transport device 311 serves the transfer positions P2a (analogous to P2) and P3a (analogous to P3) from and into racks 320-1 and 320-2, respectively, analogously as shown in Figures 1 to 5, and the other transport device 312 serves the transfer positions P2b and P3b from and into racks 330-1 and 330-2, respectively.

[0176] For example, in filling area III, four filling stations 130 with corresponding conveying sections 230a to 230d and transfer positions P4a to P4d are provided. As an example (optional), a filling device 510 movable on guides 520 is provided for all filling stations 130, analogous to Fig. 5.

[0177] As an example, demolding area IV includes four demolding stations 110 with corresponding conveying sections 210a to 210d and transfer positions Pia to Pld. Optionally, additional workstations 140 with corresponding conveying sections 240a to 240d are provided, analogous to Fig. 4. In further embodiments, it is possible to provide additional workstations 140 for only one or more of the demolding stations 110.

[0178] By way of example, analogous to Fig. 3, two lateral setup areas 11-1 and 11-2 (arranged transversely next to the rack storage 300) are provided with corresponding setup stations 120 and corresponding transverse conveyor sections 220a to 220d and corresponding transfer positions P5a to P5d. Here, the transfer positions P5a and P5b are provided, analogous to Fig. 1, by way of example, at storage locations of the rack 320-1 on a ground level, with the transfer positions P5c and P5d being provided, by way of example, on the transversely opposite side at storage locations of the rack 330-2 on a ground level.

[0179] Fig. 7A shows an exemplary schematic top view of a system for producing concrete products by casting according to some further embodiments, and Fig. 7B shows an exemplary schematic sectional view of the system according to Fig. 7A along the section line A - A.

[0181] Ulrich Schlüsselbauer

[0182] A more detailed exemplary construction based on the principle shown in Fig. 6 is provided here, with a first rack storage unit 320 having one aisle and a transport device 311 moving within it, and a second rack storage unit 330 running parallel in the longitudinal direction X, also with one aisle and a transport device 312 moving within it. Four rack rows are provided by way of example, with only eleven storage locations per rack row and rack level, with the corresponding setup areas 11-1 and 11-1 each having five setup stations (see, for example, Fig. 7A) located transversely to the sides.

[0183] For example, the shelf levels are designed at different heights (see e.g. Fig. 7B), with the penultimate upper shelf level being lower to efficiently store lower molds without wasting space. Furthermore, for example, a shelf level is provided below the base level (e.g., hall floor HB) (see e.g. Fig. 7B).

[0184] Analogous to Fig. 6, in the demolding area IV according to Fig. 7A, only four demolding stations are provided by way of example, and in the filling area III, only four filling stations are provided by way of example, which can be operated by the filling device 510 which can be moved in the transverse direction Y (see e.g. Fig. 7A).

[0185] In the above embodiments, it is particularly advantageous that at least one rack storage system extending in the longitudinal direction X with two rows of racks can be provided, wherein two work areas with several workstations can be provided at longitudinally opposite ends of the rack storage system, which can be served via transfer positions at longitudinally opposite ends of the rack storage system, wherein at least one further work area (above only by way of example the setup area) is arranged transversely laterally to the side of the rack storage system and is served transversely from rack storage locations of a rack lying on a base plane.This results in an advantageously compact design with space-saving intermediate storage of the molds, also for curing after filling with concrete. At least three work areas can be arranged compactly around the rack storage system and each can be served directly from the rack storage system with short conveying distances using only one rack storage transport system. A particularly preferred, space-saving design can be provided with four rack rows and four adjacent work areas as shown in Fig. 6 and / or Figs. 7A and 7B.
