[0002] SCOPE OF APPLICATION AND STATE OF THE ART

[0003] The invention relates to a method for detecting at least one position-related property of the building material and / or viscous material of a material section within a quantity of building material and / or viscous material, wherein the quantity of building material and / or viscous material is positioned within a conveying target area. The invention further relates to a building material and / or viscous material conveying system for such a method.

[0004] TASK AND SOLUTION

[0005] It is an object of the present invention to provide a method for detecting at least one position-related property of a building material and / or thickening agent within a quantity of building material and / or thickening agent positioned within a conveying target area, as well as a building material and / or thickening agent conveying system for such a method, each exhibiting improved properties. In particular, it should be possible to identify at least one position-related property of a building section which building section is produced with and / or from the material section of a building material and / or thickening agent quantity.

[0006] This problem is solved by the subject matter of the independent patent claims. Preferred embodiments are the subject matter of the dependent patent claims.

[0007] A method according to the invention serves to detect at least one position-related property of a material section and / or thickener within a quantity of material and / or thickener. The quantity of material and / or thickener that locally exhibits the material section with the at least one detected property is positioned within a conveying target area. The quantity of material and / or thickener positioned within the conveying target area forms a structural component of a structure there. The material section exhibited by the positioned quantity of material and / or thickener can form a local section of the structural component.

[0008] The method includes a step in which construction material and / or viscous material is conveyed along a conveying path of a construction material and / or viscous material conveying system to position the quantity of construction material and / or viscous material in the conveying target area. The method also includes a step in which at least one material segment of the construction material and / or viscous material conveyed along the conveying path is defined for the quantity of construction material and / or viscous material. This material segment can therefore be defined, in particular, before it is added to the quantity of construction material and / or viscous material positioned in the conveying target area.

[0009] Furthermore, the process includes a step in which at least one property of the building material and / or thickening agent in the material section is recorded, as well as – alternatively or additionally – at least one property of the building material and / or thickening agent conveying system. In particular, the at least one property of the material section is recorded before the material section has been fed into the quantity of building material and / or thickening agent positioned in the conveying target area. During the recording of the at least one property, property data representing that at least one property are generated and collected.

[0010] The process further includes a step in which a conveying target position is recorded within the conveying target area. Following conveying, the material section, including the bulk material and / or thickener, is positioned at the conveying target position, and position data representing this position is generated and collected. By positioning the material section at the conveying target position, it is added to the bulk material and / or thickener quantity located within the conveying target area, specifically to replenish the bulk material and / or thickener quantity.

[0011] Furthermore, the process includes a step in which collected property data is assigned to collected position data in such a way that a data set with corresponding property and position data is generated. This data set is generated to capture at least one property of the granular and / or viscous material of the material section, related to the conveying target position, within the quantity of granular and / or viscous material positioned within the conveying target area.

[0012] This allows documentation of where, within the target area, construction material and / or thickening material with which properties was positioned. In particular, this makes it possible to track where a structure built with the construction material and / or thickening material within the target area exhibits which specific properties.

[0013] In particular, the invention makes it possible to trace precisely where within a structure constructed with and / or from the building material and / or thickening material certain properties of the building material and thickening material are present or were present, at least temporarily. If material defects in the building material and thickening material are detected, for example, after completion of the structure, this method can be used to identify precisely where repair work may need to be carried out within the structure.

[0014] The building material can be a viscous substance. It can be a paste-like mixture of different materials. The viscous substance can be mortar, cement, screed, or concrete, each in a mixable and / or pumpable state. In this mixable and / or pumpable state, the viscous substance is not yet hardened and / or set.

It is conceivable that the mobile delivery device includes the mixing device. In particular, the batch of material is supplied to be conveyed along the conveying path of the construction and / or viscous material conveying system.

[0027] In a further embodiment of the invention, the displacement volume depends on at least one at least partial, in particular a complete, stroke of a displacement body of the construction and / or high-viscosity pumping device, in particular wherein the displacement body is in the form of a conveying piston of the construction and / or high-viscosity pumping device.

[0028] In a further embodiment of the invention, the method includes a step in which at least one property of the building material and / or thick material is detected and - alternatively or additionally - at least one property of the building material and / or thick material conveying system is entered, in particular manually, before the building material and / or thick material is conveyed along the conveying path.

[0029] In a further embodiment of the invention, at least one property is temperature. Alternatively or additionally, at least one, in particular another, property is a penetration resistance of the building material and / or thickening material. Further alternatively or additionally, at least one, in particular another, property is a yield stress of the building material and / or thickening material.

Further alternatively or additionally, the building material and / or thickening material conveying system can have a mechanical device arranged in the conveying path to engage the conveyed building material and / or thickening material in such a way that it experiences a torque and / or force as a result of the engagement, wherein the magnitude of the torque and / or force determines at least one, in particular another, property of the building material and / or thickening material.

[0030] A construction and / or high-viscosity material conveying system according to the invention is designed for a process according to the invention as described above. In particular, the construction and / or high-viscosity material conveying system can be used to carry out the process according to the invention. The construction and / or high-viscosity material conveying system has a conveying path. Construction and / or high-viscosity material can be conveyed along the conveying path. In addition, the construction and / or high-viscosity material conveying system has an electronic control device that is set up for carrying out the process and is also programmed – alternatively or additionally. The advantages of the process according to the invention, as explained above, also apply to the construction and / or high-viscosity material conveying system according to the invention.

[0031] In an embodiment of the invention, the construction and / or viscous material conveying system comprises at least one property detection device for detecting at least one property of the material section of construction and / or viscous material conveyed along the conveying path, and—alternatively or additionally—for detecting at least one property of the construction and / or viscous material conveying system itself.

[0036] The invention can enable unambiguous 3D printing documentation.

[0037] The invention can enable the identification of components manufactured with unacceptable material properties. Hardened concrete properties can be heterogeneous, especially in construction processes such as 3D printing. Therefore, it can be important to know the concrete properties in conjunction with small component sections, each corresponding to a specific material section. Should it turn out that the concrete properties were unacceptable at a particular point during 3D printing, the invention can be used to identify the printed component with the material in question, so that corrective measures can be taken if necessary.

[0038] The following scenario for the application of the invention is conceivable: Construction debris is dumped onto a rubble heap by an excavator and a truck. Individual material increments, in particular material sections, can be assigned to a loading hopper of the truck and / or a bucketful of the excavator. For example, the mass, volume, type, and other dimensions of the construction and / or heavy material load can be assigned as properties to the truck. For example, when unloading the bucketful of material from the excavator, the position of the bucketful, the degree of fill, and other dimensions can be recorded as properties. Thus, the material dumped onto the rubble heap and its quantity can be identified, making it easy to locate any pollutants that may be discovered later.The same principle can be applied to a structure, such as a dam, so that a clear evaluation can take place based on the generated data, so that the structure can be documented and / or rework can be more easily identified, defined and carried out.

[0039] The properties of the construction and / or thickened material can be continuously monitored. Inline measurement, performed within the material processing chain, can be used to record these properties. The construction and / or thickened material conveying system can be incrementally segmented to allow for the explicit determination of the absolute position of each material segment within the system. Material and machine data for at least one property can be acquired outside, along, or downstream of the construction and / or thickened material conveying system.

The quantity M of construction material and / or thickening agent denotes a quantity of construction material and / or thickening agent B positioned within a conveying target area TA. The conveying target area TA can, for example, define a structure BW and – alternatively or additionally – a structure component BWT, in particular geometrically. According to the method, at least one position-related property E of construction material and / or thickening agent B of a material section I, 11 to 114 is thus detected in the quantity M of construction material and / or thickening agent.

[0048] The method is carried out in the present case by means of a construction and / or viscous material conveying system 1 according to the invention. The construction and / or viscous material conveying system 1 has a conveying path 2. Construction and / or viscous material B is conveyed along the conveying path 2. The construction and / or viscous material conveying system 1 has an electronic control device 10. The electronic control device 10 is configured to carry out the method and is also programmed – alternatively or additionally.

[0049] According to the method, the construction and / or viscous material B is conveyed along conveying path 2 so that the quantity M of construction and / or viscous material is positioned in the conveying target area TA. For example, the quantity M of construction and / or viscous material is positioned in the conveying target area TA after the construction and / or viscous material B has been conveyed and has thus left the construction and / or viscous material conveying system 1. According to the method, at least one material section I, 11 to 114 of construction and / or viscous material B is defined while the construction and / or viscous material B is conveyed along conveying path 2. Subsequently, the material section I, 11 to 114 of construction and / or viscous material M is added to the conveying target area TA.

[0050] According to the procedure, at least one property E of the construction and / or viscous material B of material section I, 11 to 114 is recorded. Alternatively or additionally, at least one property E of the construction and / or viscous material conveying system 1 is recorded.

[0051] According to the procedure, a conveying target position T, T1 to T14 is recorded within the conveying target area TA. The construction and / or thick material B from material section I, 11 to 114 is then positioned in the recorded conveying target position T, T1 to T14 following its conveying. Position data PD, representing the conveying target position T, T1 to T14, are generated and collected.

[0052] According to the procedure, collected property data ED are assigned to collected position data PD, so that a data set DS is generated with corresponding property data ED and position data PD. By generating the data set DS, at least one property E of the construction and / or thick material B of the respective material section I, 11 to 114, in the quantity M of construction and / or thick material positioned within the delivery target area TA, is recorded. This property relates to the delivery target position T, T1 to T14.

[0056] The at least one material section I, 11 to 114 can be defined by a temporal and – alternatively or additionally – spatial increment, in particular of the quantity of construction material and / or thickening agent M. The steps of the process can be carried out as presented here for several material sections I, 11 to 114 of construction material and / or thickening agent B conveyed along conveying path 2.

Alternatively or additionally, the conveying path 2 can be defined, at least in part, by a gravity and / or projectile trajectory D for the conveyed construction and / or viscous material B.

[0059] For example, section I, 11 to 114 is defined with reference to a displacement volume V of the construction and / or high-viscosity pumping unit 3 of the construction and / or high-viscosity conveying system 1. The displacement volume V can depend on at least a partial, and in particular a complete, stroke of a conveying piston 7 of the construction and / or high-viscosity pumping unit 3.
