Description

[0001] The present invention relates to a heating system for heating a shaping element of a stone molding machine, a stone molding machine, a multi-component plug-in system for a heating system for heating a shaping element of a stone molding machine, a method for manufacturing a multi-component plug-in system for a heating system for heating a shaping element of a stone molding machine, and a method for manufacturing a heating system for heating a shaping element of a stone molding machine.

[0002] Various stone-forming machines for shaping stones from a mixture, such as concrete, are known from the prior art. The mixture is typically placed in a mold cavity and then shaped, demolded, and hardened. The stones formed in this way can be used as building material, for example, for constructing houses or roads.

[0003] To achieve particularly dense and closed stone surfaces, it is also known to integrate heating systems into stone forming machines, which enable the heating of the mixture in the mold cavity and also reduce the cycle time in the production of stones.

[0004] Furthermore, it is known that consistent quality of the stones can be ensured primarily through vibration systems, which vibrate the mixture during the stone-making process. This vibration allows the stones to be given a comparatively smooth surface. Additionally, vibration offers the advantage of improving the dimensional accuracy of the produced stones, which in turn reduces waste and improves stone manufacturing.

[0005] However, vibrating the mixture with a vibration system can damage the heating system. This can, for example, lead to unevenly hardened and consequently unevenly formed bricks, especially if damage to the heating system goes unnoticed. Repairing the heating system is usually very complex and causes undesirable downtime in brick production.

[0006] Against this background, document DE 10 2004 015 378 A1, for example, proposes the use of a radiant heat source. The radiant heat source advantageously allows the mixture to be formed into stone to be heated without exposing the heat source to the risk of damage from vibration.

[0007] It is therefore an object of the present invention to provide an improved heating system for heating a shaping element of a stone forming machine, in particular an improved heating system for conductive heating of a shaping element of a stone forming machine, wherein the heating system in particular enables efficient production of stones by the stone forming machine.

[0008] Furthermore, it is an object of the present invention to provide an improved multi-component plug-in system for a heating system for heating a shaping element of a stone molding machine, in particular for an improved heating system for conductive heating of a shaping element of a stone molding machine, wherein the multi-component plug-in system in particular enables efficient production of stones by the stone molding machine.

[0009] Furthermore, it is an object of the present invention to provide an improved heating, in particular a conductive heating, stone forming machine which in particular enables the efficient production of stones.

[0010] Furthermore, it is an object of the present invention to provide a method for manufacturing a multi-component plug-in system for a heating system for heating a shaping element of a stone molding machine, as well as a method for manufacturing a heating system for heating a shaping element of a stone molding machine, which in particular enables efficient production of stones by the stone molding machine.

[0011] The aforementioned tasks are solved by the subject matter of the independent claims; certain embodiments are the subject matter of the dependent claims.

[0012] A first aspect of the invention relates to a heating system for heating, in particular conductively, a shaping element of a stone forming machine for forming a stone from a mixture, wherein the heating system comprises: at least one heating element; a housing with at least one power input terminal and several power output terminals, wherein the power input terminal has a wire bundle and a connector pluggable from outside the housing to connect the power input terminal to a power supply, in particular to connect it reversibly and detachably, and wherein the power output terminals are electrically conductively connected to the at least one heating element; wherein each power output terminal has at least one wire and a connector pluggable from outside the housing, and wherein the wires of the power output terminals are not non-destructively detachable from the wire bundle of the power input terminal inside the housing.

[0013] The power output connector, which can be plugged in from outside the housing, can in particular be a connector integrated into the housing, for example, a connector integrally manufactured with the housing. Furthermore, the power output connector, which can be plugged in from outside the housing, can be arranged at a distal end of the power output connector that projects from the housing, or in other words, from a housing wall, outwards.

[0014] The power input connection, which is equipped with a connector, together with the power output connections, which also have connectors, makes the respective connections advantageously accessible from outside the housing.

[0015] Furthermore, the housing can be advantageously pre-assembled with at least one power input connection and several power output connections.

[0016] This means that the housing, along with at least one power input connector and several power output connectors, can be advantageously replaced as a whole. This, in turn, allows for easy repair or, in other words, simple replacement of the housing along with at least one power input connector and several power output connectors, right up to the respective connectors.

[0017] The connector of the at least one power input terminal can advantageously be easily disconnected from the power supply, for example by actuating a reversible coupling device of the connector of the at least one power input terminal.

[0018] The connectors of the multiple power output terminals can also be easily separated from at least one heating element, for example by actuating a reversible coupling device of a respective connector of the multiple power output terminals.

[0019] Connectors are advantageously vibration-stable, or in other words, vibration-insensitive, so that the heating element in question can be advantageously and durably arranged on a shaping element that is shaken by a vibration device.

[0020] Furthermore, the non-destructively connected conductors of the power output terminals, which are connected to the conductor bundle of at least one power input terminal, are advantageously stiffened and thus vibration-stable or, in other words, vibration-insensitive.

[0021] The connections between the terminals, especially within the housing, are therefore advantageously designed for durability. This is preferable to, for example, wires and / or wire bundles connected using terminal blocks, which are reversibly fixed by screw connections. Such screw connections can loosen due to vibrations from a shaking device, and / or cable breaks can occur, particularly near the screw connections used to secure the wires and / or wire bundles.

[0022] The wires of the power output terminals can, in particular, be directly connected to a wire bundle of at least one power input terminal.

[0023] This allows the individual conductors and the conductor bundle to be advantageously rigid relative to each other. Furthermore, the weight of the heating system can be advantageously reduced. In particular, vibrating components relative to the individual conductors and / or the conductor bundle, which could, for example, cause a cable break or a conductor break, can be reduced or eliminated.

[0024] At least one conductor of a power output connection can include or consist of at least one phase, a neutral conductor and a protective conductor.

[0025] The conductor bundle of the power input connection can comprise a bundle of conductors. Each conductor of the conductor bundle can include or consist of at least one phase conductor, one neutral conductor, and one protective conductor.

[0026] In exemplary embodiments, a power output terminal of the power output terminals can include or consist of at least one conductor as phase and one conductor as neutral, and optionally additionally include or consist of a conductor as protective conductor.

[0027] This makes it advantageous to supply a heating element with power, or in other words, with electricity, via the power output connection.

[0028] In alternative embodiments, a power output connection may only comprise or consist of one conductor as phase, one conductor as neutral and one conductor as protective conductor.

[0029] This allows individual, especially identical, conductors of the power output terminals to be connected to a similar conductor bundle of at least one power input terminal. Advantageously, this facilitates the division of the conductors within the housing into identical conductors for connection to the conductor bundle of the at least one power input terminal.

[0030] The term "similar conductors" refers to conductors that are all of the same type. In other words, "similar conductors" describes conductors that all have the same type of phase, neutral, and protective earth conductor.

[0031] Similarly, a similar bundle of veins describes a bundle of veins that consists exclusively of veins of the same type, i.e., exclusively of similar veins.

[0032] The at least one heating element can be designed as a conductive heating element, but is not limited to this. Alternatively or additionally, the at least one heating element can be designed as a heating element that heats primarily by means of radiation.

[0033] The heating element advantageously reduces the adhesion of the mixture to one or more surfaces heated by the heating element, thereby improving the quality of the stone.

[0034] A radiant heating element advantageously reduces the risk of damage during vibration and simultaneously ensures high-quality stone production.

[0035] A conductive heating element advantageously enables distributed and simultaneously targeted heating of a mixture adjacent to a shaping element during the production of a stone.

[0036] The forming element can, in particular, be part of a mold cavity of a stone molding machine and / or part of a cover element of a stone molding machine. The cover element can, in particular, be configured to form a lid for the mold cavity or, in other words, to at least partially cover the mold cavity in a stone-forming operating state. The cover element and the mold cavity can be configured to jointly form a cavity that is substantially closable with the mixture used to form a stone. The mold cavity can be arranged on a base element, for example, in the form of a base plate, which closes the cavity at the bottom. The forming element can form the mold cavity of a stone molding machine and / or be part of a cover element of a stone molding machine and / or be part of a base element of the stone molding machine.In particular, several forming elements can be comprised of a mold cavity and / or a top element and / or a bottom element. If the mold cavity and / or the top element and / or the bottom element comprises several forming elements, one or more, preferably all, forming elements can be heated. In other words, the mold cavity can have one or more honeycomb sections with side walls, closed at the top by the top element and at the bottom by the bottom element. One or more, in particular all, of the side walls can each comprise a conductive heating element and thus be heated. Alternatively or additionally, the top element can comprise one or more heating elements. Alternatively or additionally, the bottom element can comprise one or more heating elements.

[0037] The cover element can, without being limited to, be in the form of a plate, and / or in particular contoured, for example to shape the mixture into a stone with a predetermined contour.

[0038] The base element can, without being limited to, be plate-shaped and / or, in particular, contoured, for example to shape the mixture into a stone with a predetermined contour.

[0039] In other words, the heating system, and in particular at least one heating element of the heating system, can be designed to heat a mold cavity and / or a top element and / or a bottom element, especially conductively.

[0040] The shaping element can, in particular, be part of a shaping unit of the stone-molding machine. Explanations regarding the shaping unit, as described herein for other aspects, also apply accordingly to the aspect concerning the heating system.

[0041] In the following sections, various terms will be used repeatedly, the understanding of which should be facilitated by the definitions below.

[0042] Non-destructive disconnection: The connection between the conductors of the power output terminals and the conductor bundle of at least one power input terminal is described as non-destructive. This non-destructive connection can be a material bond, such as one created by soldering and / or ultrasonic welding and / or another non-destructive joining method. Disconnecting such a non-destructive connection involves, in particular, at least partial or complete destruction of at least one of the conductors of the power output terminals and / or at least of the conductor bundle of the power input terminal. The destruction of a conductor or conductor bundle is defined here as at least partial or complete severance of the conductor's cross-section or the partial or complete severance of at least one conductor of the conductor bundle.

[0043] The non-destructive connection defines in particular a distinction from a reversibly detachable connection, such as a screw connection of conductors, for example for fastening to a terminal block, whereby by unscrewing the screw in question a conductor can be reversibly detached from the terminal block.

[0044] If a value, spatial measure, spatial ratio or other ratio is given with the addition of "essentially" or "approximately" or "about", this addition is intended to indicate, in particular, a deviation from the relevant measure or ratio in the range of 0% to 10%.

[0045] In this context, a conductor describes a single wire with a predetermined cross-section. A conductor can, but is not limited to, comprise or consist of, in particular, a copper wire and / or an aluminum wire. A conductor can, but is not limited to, have a cross-sectional area of, in particular, approximately 0.5 mm² to approximately 5 mm².

[0046] The power input connection can have a power-dependent cross-section for each conductor. In exemplary embodiments, particularly without grounding, the power input connection can have a cross-section of up to approximately 2.5 mm² for a power output of less than approximately 12 kW, a cross-section of up to approximately 4 mm² for a power output of less than approximately 16 kW, and a cross-section of approximately 5 mm² for a power output of more than approximately 16 kW.

[0047] The power output terminal can have a cross-section of approximately 1 mm² to approximately 2 mm², and in particular approximately 1.5 mm². An earth connection, which can be configured as the earth connection of the power input terminal or, in particular, as a separate earth connection, can have a cross-section of approximately 4 mm².

[0048] In exemplary embodiments, the heating system can comprise a damping material in which one or more conductors, or in particular all conductors, i.e. the conductors of the power output connections, are embedded.

[0049] Alternatively or additionally, the wire bundle of the power input terminal can be embedded in a damping material. This damping material can be, but is not limited to, the same as that used to embed the wires of the power output terminals.

[0050] The damping material can be arranged particularly inside the housing.

[0051] The damping material is specifically designed to at least partially embed the conductors of the power output connections and / or at least one conductor bundle of the power input connection.

[0052] The wires of the power output terminals and / or at least one wire bundle of the power input terminal can be connected to the housing by means of the damping material.

[0053] The damping material is advantageously designed to dampen vibrations of the heating system, and in particular of the heating element and / or the housing, towards the conductors and / or the at least one bundle of conductors.

[0054] The damping material advantageously reduces movement of the conductors relative to the housing and / or relative to at least one heating element, particularly during vibration of a forming element in the production of a stone, where the forming element may be part of a mold cavity and / or a cover element of a stone molding machine. Thus, the risk of cable breaks in the conductors and / or the at least one conductor bundle can be advantageously reduced or avoided over a comparatively long service life.

[0055] In exemplary embodiments, the damping material can comprise or consist of at least one of silicone, a foam, and a potting compound. The potting compound can comprise a polymer, particularly a curable one, and can, but is not limited to, comprise or consist of, for example, an elastomer, polyurethane, epoxy, polycarbonate, and / or polyamide.

[0056] Alternatively or additionally, the damping material can include or consist of one or more fastening clips. Fastening clips allow for advantageously simple handling and, in particular, ensure advantageously simple reversible release. Furthermore, fastening clips can be advantageously and easily provided with a predetermined stiffness and corresponding damping properties.

[0057] Silicone advantageously allows for targeted damping and, in particular, targeted damping fastening of wires and / or one or more wire bundles in the housing.

[0058] Foam advantageously allows for a weight-saving, damping embedding of wires and / or one or more wire bundles in the housing.

[0059] The foam can be pre-shaped and / or pre-cut, particularly based on the individual wires and / or one or more wire bundles within the housing. This makes the foam easy and quick to install in the housing. Furthermore, the foam can advantageously ensure repeatable and accurate positioning of the wires and / or wire bundles relative to the housing.

[0060] The potting compound advantageously enables the secure embedding of individual wires and / or one or more wire bundles within the housing. Furthermore, it can advantageously improve the conductive heat dissipation from the housing. Additionally, the wires and / or wire bundles within the housing can be advantageously electrically insulated.

[0061] Furthermore, the potting compound can advantageously improve the sealing of the housing, for example against the ingress of water and / or dust, particularly according to an IP class such as IP 65. This makes the heating system advantageously easy and safe to clean, for example using a high-pressure cleaner.

[0062] In exemplary embodiments, the conductors can be bonded together by means of a material bond, for example by soldering, or they can be ultrasonically welded. It is understood that the present embodiments are not limited to these methods, and that other non-destructively detachable connections for joining the conductors, i.e., for connecting the conductors of the power output terminals to the at least one conductor bundle of the power input terminal, are possible.

[0063] Some or all of the several conductors can be connected to at least one conductor bundle. In particular, only conductors of the same type can be connected to a given conductor bundle within a plurality of conductor bundles of the power input terminal.

[0064] Soldering offers a simple and advantageous way to connect individual wires to a wire bundle, stiffening them and allowing for non-destructive joining. Ultrasonic welding offers a particularly vibration-resistant and advantageous way to connect individual wires to a wire bundle, stiffening them and allowing for non-destructive joining.

[0065] The non-destructive joining, especially by means of soldering and / or ultrasonic welding, enables an advantageously long-lasting connection of the conductors to the conductor bundle.

[0066] Furthermore, the non-destructive connection allows the housing with the at least one power input connection and the multiple power output connections to be advantageously pre-assembled. In particular, the housing with the at least one power input connection and the multiple power output connections is advantageously durable on the one hand, and advantageously easy and quick to replace on the other.

[0067] For example, the housing, together with the at least one power input terminal and the multiple power output terminals, in particular together with their respective connectors, can be reversibly separated at the respective connectors and then removed together. For example, the housing, together with the at least one power input terminal and the multiple power output terminals, in particular together with their respective connectors, can be removed as a whole from a forming element and replaced accordingly as a whole.

[0068] This allows for the provision of a heating system with a long service life that is also advantageously easy to repair. In particular, the present heating system is especially production-efficient to repair, since replacing the housing along with at least one power input connection and the multiple power output connections is significantly more time-efficient than troubleshooting by replacing individual defective wires and / or wire bundles.

[0069] Furthermore, replacing the housing is advantageously possible without electrical specialists, as the pre-assembled housing can be exchanged without requiring a potentially complex examination of its contents. In other words, replacement or repair is significantly simplified and can therefore be carried out in a time-efficient and cost-effective manner.

[0070] In exemplary embodiments, similar conductors of at least one of the power output terminals can be connected within the housing to form a single, (in itself) identical conductor bundle, in particular to form a single, identical conductor bundle of the power input terminal.

[0071] The power input terminal's at least one wire bundle can comprise one or more identical wire packages. For example, one identical wire package can correspond to a specific wire bundle of the power input terminal.

[0072] For example, only conductors corresponding to one phase of the power output terminals can be connected to form a single-phase conductor bundle. Alternatively or additionally, only conductors corresponding to a neutral conductor of the power output terminals can be connected to form a neutral-conductor conductor bundle. Furthermore, alternatively or additionally, only conductors corresponding to a protective conductor of the power output terminals can be connected to form a protective-conductor conductor bundle.

[0073] In exemplary embodiments, the power input connection can comprise one or more (internally) identical wire bundles.

[0074] In other words, the power input connection can, in particular, comprise a bundle of conductors consisting exclusively of conductors corresponding to a phase. Alternatively or additionally, the power input connection can, in particular, comprise a bundle of conductors consisting exclusively of conductors corresponding to a neutral conductor. Furthermore, alternatively or additionally, the power input connection can, in particular, comprise a bundle of conductors consisting exclusively of conductors corresponding to a protective conductor.

[0075] The (internally) identical wire bundles can each comprise one or more (internally) identical wire packages. It is understood that the respective type of wire bundle corresponds to the respective type of wire package and, furthermore, specifically also to the respective type of wire, i.e., uniformly either phase, neutral, or protective conductor.

[0076] One or more (internally) identical wire packages can each form a (internally) identical wire bundle.

[0077] In exemplary embodiments, the power input connection may comprise only a single bundle of conductors, which is connected, for example, only to conductors of a predetermined type, in particular phase or neutral conductor.

[0078] In further exemplary embodiments, the power input connection can comprise only two wire bundles, wherein in particular a first wire bundle is connected only to wires of a predetermined type of phase, neutral or protective conductor, and wherein in particular a second wire bundle is connected only to wires of a different type of phase, neutral or protective conductor than the first wire bundle.

[0079] The protective conductor can, for example, be directly connected to the housing, in particular without being part of the power input terminal that can be connected to a power supply.

[0080] In an embodiment where the power output terminals include a protective conductor, this conductor can, for example, be connected to the grounded enclosure. In other words, the protective conductor can be directly connected to the enclosure, with the enclosure being directly connected to a protective conductor.

[0081] In further exemplary embodiments, the power input connection can comprise (exactly) three wire bundles, wherein in particular a first wire bundle is connected only to wires of the type phase, a second wire bundle is connected only to wires of the type neutral conductor, and a third wire bundle is connected only to wires of the type protective conductor.

[0082] The conductors of the power output connections can thus be advantageously rigidly connected to individual and, in particular, identical conductor bundles. Furthermore, the conductors of the power output connections can be advantageously rigidly connected to individual and, in particular, identical conductor bundles of the power input connection. The conductors and the at least one conductor bundle are thereby advantageously durable and, in particular, can be directly connected to each other within the housing.

[0083] This eliminates the need for additional connecting elements, which would significantly increase the weight of the housing. This, in turn, allows for a reduction in the weight of the heating system and simultaneously minimizes the relative movement between the wires and / or wire bundles and the otherwise necessary connecting elements. This, in turn, significantly reduces the risk of cable breaks.

[0084] In exemplary embodiments, the heating system can be configured to distribute a heating power of more than approximately 4 kW, in particular in the range of approximately 4 kW to approximately 20 kW, preferably in the range of approximately 5 kW to approximately 16 kW, more preferably in the range of approximately 8 kW to approximately 13 kW, in particular of approximately 11 kW, from a single power input connection of the at least one power input connection to a plurality of power output connections.

[0085] This allows for the advantageous provision of heating power suitable for the production of stones, which in particular makes it possible to achieve a dense and closed stone surface of the stone to be produced.

[0086] The heating capacity is particularly suitable for heating a predetermined area and / or volume of a mixture to be formed into a stone, especially from approximately room temperature, by about 20 °C to about 50 °C, for example by about 40 °C. The heating system can be configured, in particular, to heat the mixture to be formed into a stone to a temperature of about 40 °C to about 70 °C, preferably to a temperature of about 50 °C to about 60 °C.

[0087] Alternatively or additionally, the heating system can be designed to heat the mixture to be formed into the stone with a heating power related to the area of ​​the mixture, for example with a heating power related to the area of ​​the mixture of about 1 to about 10 W / cm², in particular of about 1 to about 3 W / cm², preferably of about 2 W / cm².

[0088] The mixture may, but is not limited to, include or consist of concrete, in particular water-mixed concrete, for example concrete with a predetermined water content.

[0089] In exemplary embodiments, the wires of the power output connections within the housing can have substantially the same length.

[0090] In further exemplary embodiments, the conductors of the power output terminals can have a substantially equal length from the connector of the respective power output terminal to the connection with the at least one conductor bundle of the power input terminal.

[0091] An essentially equal length of the conductors of the power output connection is defined in particular as a length of each conductor of a power output connection which deviates by less than about 20%, in particular less than 10%, preferably less than about 5% from a length of the conductors of the other power output connections, in particular from an average value of the lengths of the conductors of the other power output connections, especially if the respective conductors of the power output connections have the same cross-section.

[0092] The substantially equal lengths of the conductors within the housing and / or between the connector of the power output terminals and the connection with the at least one conductor bundle advantageously ensure a substantially equal resistance of the power output terminals within the housing and / or up to the point of connection to a heating element. This advantageously ensures a uniform and, in particular, a uniformly long-lasting power distribution. Furthermore, it advantageously ensures a substantially uniform heat distribution within the housing.

[0093] In exemplary embodiments, the power input connection for water and / or dust can be located close to the housing. Alternatively or additionally, the power output connections for water and / or dust can be located close to the housing.

[0094] The at least one power input connection and / or the power output connections can each be routed into the housing through a respective feedthrough. The feedthrough(s) can be formed, in particular, in a housing wall.

[0095] The opening(s) in the housing can be sealed against the ingress of water and / or dust.

[0096] The bushing(s), and in particular the housing as a whole, can be protected against the ingress of dust and / or water according to IP 65. The bushing(s) can each, for example, incorporate an IP 65-rated sealant. The bushing(s) can thus be advantageously designed for the tight sealing of the respective power input connection and the multiple power output connections on the housing.

[0097] The housing may, in particular, have a housing cover which seals the housing tightly.

[0098] The housing may, but is not limited to, include or consist of a plastic and / or a metal, such as steel or aluminum.

[0099] The present housing is therefore advantageously sealed.

[0100] Furthermore, the housing can be integrally designed as an element protecting the conductors and at least one conductor bundle, and can also be grounded. The housing can thus, for example, provide an integral connection for the protective conductor of the power output terminals. In addition, the housing is advantageously easy to clean from the outside, for example using a high-pressure cleaner, while the conductors and at least one conductor bundle are advantageously protected.

[0101] In exemplary embodiments, the power output connections can be reversibly detachable from the at least one heating element.

[0102] This means that the housing, which is pre-assembled with at least one power input connection and several power output connections, can be easily separated from the at least one heating element and thus easily replaced. This, in turn, ensures high efficiency in the production of bricks.

[0103] In exemplary embodiments, the power input connector can have a positive-locking coupling device for a complementary power supply connector, in particular a bayonet coupling device. Alternatively or additionally, one or more, in particular all, of the power output connectors can have a positive-locking coupling device for a complementary connector of a heating element. Thus, at least one heating element, in particular each heating element, can have a connector that is complementary to one or more, in particular all, of the power output connectors.

[0104] The coupling device can, in particular, comprise an engaging means and an engaging means. In other words, one of the connectors and the complementary connector can have an engaging means, and the other of the connectors and the complementary connector can have a complementary engaging means.

[0105] A positive-locking coupling device advantageously enables a secure, reversible connection. Furthermore, a positive-locking coupling device advantageously allows forces generated, for example, by vibration, to be at least partially transmitted and dissipated via the coupling device. This, in turn, can advantageously improve the service life of the conductors and / or at least one conductor bundle.

[0106] Furthermore, a bayonet coupling allows for integral coding between the respective connector and its complementary connector. This makes the pre-assembled multi-component connector system, which includes the housing, at least one power input connection, and several power output connections, advantageously interchangeable with high repeatability.

[0107] In exemplary embodiments, the positive-locking coupling device of the power output terminals can differ from the positive-locking coupling device of the power input terminal. This can advantageously prevent faulty coupling.

[0108] In exemplary embodiments, the at least one heating element can comprise an aluminum-encased wire and / or a heating mat. Alternatively or additionally, the heating element can comprise a metal plate, in particular an aluminum plate, milled for heating wires, wherein one or more, in particular flexible, heating wires can be arranged in the milled contour.

[0109] The heating element thus advantageously enables uniform, targeted, and in particular conductive heating of a shaping element on which the heating element is arranged, as well as a correspondingly uniform heating of a mixture for the formation of a stone, which is arranged in the mold cavity.

[0110] Another aspect of the present invention relates to a stone forming machine, wherein the stone forming machine comprises: comprising a shaping element for forming a mixture to create a stone, and a heating system according to the preceding aspect, which is arranged on the shaping element.

[0111] The shaping element is specifically designed to define at least part of the contour, or in other words, the outer surface of the stone or the mixture to be formed into a stone.

[0112] The stone forming machine may in particular include a forming device which has the forming element.

[0113] The molding device can, in particular, comprise a mold base and a mold top, or in other words, a mold cavity and a cover element, which are movable relative to each other to form the mixture in the mold base or in the mold cavity into a brick. The forming element can, in particular, be part of the mold cavity and / or part of the cover element. In exemplary embodiments, at least one of the mold cavity and the cover element can form the forming element.

[0114] The at least one heating element can be arranged, in particular, across the entire surface of the shaping element. Specifically, the at least one heating element and / or the housing can be arranged on the shaping element.

[0115] The mold cavity, and in particular the forming element, can have one or more cavities for receiving the mixture.

[0143] The following describes embodiments of the invention in more detail with reference to the accompanying figures. It is understood that the present invention is not limited to these embodiments and that individual features of the embodiments can be combined to form further embodiments within the scope of the accompanying claims.

[0144] It shows: Figure 1 is a sketch of a heating system and a multi-component plug-in system according to one embodiment; Figure 2 is a sketch of wires connected to form a wire bundle according to one embodiment; Figure 3 is a sketch of a forming device of a stone forming machine according to one embodiment; Figure 4 is a flowchart for the manufacture of a multi-component plug-in system according to one embodiment; and Figure 5 is a flowchart for the manufacture of a heating system according to one embodiment.

[0145] Fig. 1 Figure 1 shows a sketch of a heating system 1 and a multi-component plug-in system 5 according to one embodiment. The heating system 1 comprises the multi-component plug-in system 5.

[0146] As in Fig. 1 As shown, the heating system 1 or the multi-component plug-in system 5 of the heating system 1 is arranged on a shaping element 2 of a stone forming machine (not shown).

[0147] The forming element 2 is shown by way of example in a bottom view sketched in an operating state, for an exemplary case where the forming element is part of a mold cavity. On its side opposite the bottom view (not shown), the forming element 2, particularly as part of the mold cavity, can have a cavity for receiving a mixture intended for the formation of a brick.

[0148] An analogous top view results when the forming element 2 is part of a cover element. On its side opposite the top view (not shown), the forming element 2 can have a cavity with webs and / or a cover section to enclose the mixture, particularly from above.

[0149] The in Fig. 1 The exemplary multi-component plug-in system 5 has in particular a housing 6.

[0150] The housing 6 is provided with at least one power input terminal 8. The power input terminal 8 is designed for connection to a power supply 16, which supplies the heating system 1 with, for example, a power of approximately 11 kW. The power input terminal 8 can be configured to provide a power output of over 4 kW, particularly in the range of approximately 4 kW to approximately 20 kW, preferably in the range of approximately 5 kW to approximately 16 kW, and more preferably in the range of approximately 8 kW to approximately 13 kW, and particularly approximately 11 kW, to the heating system 1.

[0151] The power input terminal 8 has, in particular, a connector 14. The connector 14 is, in particular, reversibly detachable and connectable to a complementary connector 15 of the power supply 16.

[0152] The connector 14 can have a positive locking coupling device, such as a bayonet coupling device.

[0153] The connector 14 can thus be advantageously and easily detachably connected to the power supply 16 in a predetermined manner and, in particular, in a coded way. Accordingly, in the event of a defect in one of the power output terminals 10 or in at least one power input terminal 8, the power input terminal 8 can be advantageously and quickly disconnected from the power supply.

[0154] To detect a defect, the heating system 1 and / or the multi-component plug-in system 5 may include one or more sensors (not shown) which are configured, for example, to measure a voltage at one or more of the power output terminals 10 and / or the at least one power input terminal 8, and / or include sensors which are configured to measure a temperature of a heating element 4.

[0155] Furthermore, the heating system 1 and / or the multi-component plug-in system 5 can include a control and / or regulation unit (not shown) which is connected to one or more sensors and is designed to detect a defect based on the measured value of the sensors.

[0156] Since the multi-component plug-in system 5 is a pre-assembled system which can be replaced as a whole, or in other words, exchanged, an exact and possibly complex defect detection can be advantageously omitted.

[0157] If a defect is detected, the power input connection 8 can advantageously be easily disconnected from the power supply 16, and in particular, it is advantageously possible to disconnect it without damage.

[0158] The pre-assembled multi-component plug-in system 5 features, as shown in Fig. 1The figure shows, in particular, a plurality of power output terminals 10, which are arranged on the housing 6. For example, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve or more power output terminals 10 can be arranged on the housing 6, and in particular be electrically connected to the at least one wire bundle 12 of the power input terminal 8.

[0159] As in Fig. 1 As shown, the power output terminals 10 are connected, in particular within the housing 6, to at least one wire bundle 12 of the power input terminal 8.

[0160] The conductors 18 of the power output terminals 10 have in particular a first distal end arranged within the housing 6, which is connected to the at least one conductor bundle 12 of the power input terminal 8 in a way that is particularly non-destructive.

[0161] The conductors 18 of the power output terminals 10 further have, in particular, a second distal end arranged outside the housing 6, on which a connector 20 for coupling with a heating element 4 is arranged. The connector 20 can, in particular, be designed for reversible coupling, especially for coupling with a complementary connector 21 of a heating element 4.

[0162] In Fig. 1 Only a single power output terminal 10 is shown connected to a heating element 4. It is understood that several or all power output terminals 10 can be connected to this heating element 4, or that each power output terminal 10 can be connected to a single heating element 4.

[0163] Within the housing 6, the power output terminals 10 are in particular at least partially stripped, especially to separate the conductors 18 of the power output terminals 10 according to their type (phase, neutral, protective conductor) and especially spatially, and to connect them to a conductor bundle 22 of identical conductors 18, as shown in Fig. 2 An example sketch is shown.

[0164] As in Fig. 1 As shown, the housing 6 in particular has a housing wall 7 which has power output feedthroughs 11 for the passage of the power output connections 10, and / or has at least one power input feedthrough 9 for the passage of the at least one power input connection 8.

[0165] The respective feedthroughs can, in particular, include sealing elements that protect the housing 6 against the ingress of dust and / or water, or in other words, seal it. The protection or seal can, in particular, comprise a seal according to IP 65, as defined at the time of filing of the present invention.

[0166] The housing 6 can in particular include a housing cover for sealing the housing 6 in the direction in which the viewer views it. Fig. 1 looks, exhibit, with the casing not shown for the sake of simplicity.

[0167] As in Fig. 1 As shown, the housing 6 can be grounded, or in other words, connected to a grounding point 30. Alternatively or additionally, the power input terminal 8 can include a protective conductor, for example, a wire bundle 12 which comprises only protective conductors.

[0168] The housing 6 can, in particular, comprise or consist of metal, especially steel and / or aluminum. This allows the housing 6 to advantageously protect the conductors 18 and / or conductor bundles 12 located within the housing 6, which are in particular stripped, and optionally also act as an integral connection for the grounding 30.

[0169] Fig. 2 Figure 1 shows a sketch of conductors 18 connected to form a conductor bundle 22, according to one embodiment. The conductors 18, as shown in Figure 1, are connected to a conductor bundle 22. Fig. 2 shown, can correspond to the 18 veins, which are in Fig. 1 are represented as conductors 18 of the power output connections 10.

[0170] Although in Fig. 2For example, only three conductors 18 are shown connected to form a conductor bundle 22. However, it is understood that a number of conductors 18 corresponding to the heating system or the multi-component plug-in system, for example two, three, four, five, six, seven, eight, nine, ten, eleven, twelve or more conductors 18 can be connected to form a conductor bundle 22.

[0171] The wire package 22 can, without being limited to, correspond to a wire bundle 12 of the power input terminal 8.

[0172] For example, the power input terminal 8 can comprise a wire bundle 12 consisting of one or more similar wire packages 22.

[0173] In other words, the power input terminal 8 can comprise a wire bundle 12 consisting of one or more identical wire packages 22, which consist exclusively of phase conductors. Alternatively or additionally, the power input terminal 8 can comprise a wire bundle 12 consisting of one or more identical wire packages 22, which consist exclusively of neutral conductors. Furthermore, alternatively or additionally, the power input terminal 8 can comprise a wire bundle 12 consisting of one or more identical wire packages 22, which consist exclusively of protective conductors.

[0174] At least in the area of ​​the connection of the conductors 18 to the conductor bundle 22, for example by soldering and / or by ultrasonic welding, the conductors 18 are preferably stripped, as shown in Fig. 2As shown by way of example. The conductors 18 can only be stripped within the housing 6. Alternatively or additionally, at least one conductor bundle of the power input terminal 8 can only be stripped within the housing 6 for easy connection to the conductors 18 of the power output terminals 10.

[0175] In Fig. 1 For the sake of simplicity, only individual wires 18 are shown connected to form a wire bundle 12.

[0176] It is understood, however, that each power output terminal 10 can comprise a plurality of conductors 18, with one or more conductors 18 corresponding to the type phase, with one or more conductors 18 corresponding to the type neutral, and optionally additionally with one or more conductors 18 corresponding to the type protective conductor.

[0177] Each of the conductors 18 of the power output terminals 10 of a predetermined type, i.e., phase, neutral or protective conductor, can in particular be connected to one or more conductor bundles 22 of this predetermined type, wherein one or more correspondingly similar conductor bundles 22 can form a conductor bundle 12 of the power input terminal 8.

[0178] The respective conductors 18 of the power output terminals 10 can thus advantageously be connected to form conductor bundles 22 or conductor bundles 12. This advantageously stiffens the conductors 18 of the power output terminals 10 and, in particular, connects them directly, without indirect connecting elements, to the one or more conductor bundles 12 of the power input terminal 8.

[0179] As in Fig. 1 As shown, damping material 24 can be introduced into the housing 6. Fig. 1The damping material 24 is shown here as an example of local application. However, it is understood that the damping material 24 can additionally or alternatively be arranged over a surface, in particular over the entire surface, within the housing 6.

[0180] For example, the housing 6 can be filled, at least partially, with a damping material 24. The damping material 24, which is introduced locally or which fills the housing 6, at least partially, can in particular comprise or consist of silicone, a foam and / or a potting compound.

[0181] The conductors 18 and / or the at least one conductor bundle 12 can be attached to the housing 6 at least partially by means of the damping material 24, such as silicone in particular, and in particular be attached locally.

[0182] Additionally or alternatively, the housing 6 may be at least partially filled with a damping material 24, such as a foam and / or a potting compound.

[0183] The conductors 18 and / or the at least one conductor bundle 12 can advantageously be embedded at least partially in the housing 6 in a damping manner by the damping material 24.

[0184] As in Fig. 1 As shown, a stone forming machine (not shown) can have a vibrating device 28 which is designed to vibrate the forming element 2.

[0185] This makes it advantageous to produce stones with improved quality using the stone forming machine.

[0186] The pre-assembled multi-component plug-in system 5 also advantageously allows for quick replacement of the multi-component plug-in system 5 in the event of a defect. This makes it possible to provide a particularly efficient stone forming machine that advantageously produces stones of high quality and, in particular, very little waste.

[0187] Fig. 3 shows an exemplary forming device 40 of a stone forming machine, which includes a heating system 1, as shown by the Figure 1 , 2 , 4 and 5 described, exhibits.

[0188] The stone molding machine, in particular the molding unit 40 of the stone molding machine, can have a mold cavity 46, which is preferably designed with one or more honeycomb-like compartments to hold a mixture. The mold cavity 46 can be arranged on a base plate (not shown) as a preferred base element.

[0189] Furthermore, the stone forming machine, in particular the forming device 40, can have a cover element 42 which, in particular during a stone-forming operating state of the stone forming machine, is designed to at least partially cover the forming cavity 46. The cover element 42 can, in particular, be designed to cover one or more, in particular all, cells of the forming cavity 46, especially during a stone-forming operating state of the stone forming machine.

[0190] The form-giving element 2, as shown by the further Figure 1 , 2 , 4 and 5 As described, the heating system 1 can in particular be part of the mold cavity 46 and / or part of the cover element 42. In other words, the heating system 1 can in particular be arranged on the mold cavity 46 and / or on the cover element 42 in order to heat the mold cavity 46 and / or the cover element 42 at least section by section, in particular conductively.

[0191] As in Fig. 3As shown, the heating system 1 and in particular a heating element 4 of the heating system 1 is arranged on the shaping element 2, in particular such that the heating element 4 is designed to heat the shaping element 2 conductively.

[0192] In the representation in Fig. 3 The forming element 2 is shown by way of example as part of the cover element 42 and is formed in particular by the cover element 42. In further exemplary embodiments, the forming element 2 can alternatively or additionally be part of the mold cavity 46 and is formed in particular by the mold cavity 46.

[0193] The vibrating device 28, as in Fig. 1 shown, can be connected to the mold cavity 46 and / or to the cover element 42 in such a way that the vibrating device 28 moves the mold cavity 46 and / or the cover element 42 by vibrating.

[0194] As in Fig. 3As shown, the cover element 42 can be part of a mold upper part 41 of a stone molding machine, in particular a molding unit 40 of a stone molding machine, and the mold cavity 46 can be part of a mold lower part 45 of a stone molding machine, in particular a molding unit 40 of a stone molding machine.
