Definitions

  • the invention is based on the knowledge that existing production systems for the generative production of components, in particular of concrete components, are inflexible. In addition, multi-part manufacturing systems have not been successful in the past because the interfaces between the multiple parts of these manufacturing systems have resulted in quality and productivity losses.
  • the invention was based on the knowledge that the two production modules, with one production module comprising the mixing unit and the other production module comprising the handling unit for the generative production of the component, in particular the concrete component, offer a division that such interface problems essentially do not occur. It was also found that such a division makes it possible to produce components, in particular concrete components, in particular with a shotcrete process, which are technically superior to those components that have been conventionally produced.
  • Concrete is to be understood in particular as the still young, workable concrete.
  • the concrete is produced in particular by mixing the first concrete component and the second concrete component with one another.
  • the concrete component can, for example, be an aggregate, a mixing water, concrete additives and / or a hydraulic binder such as cement and / or an alkaline-activated binder and / or a geopolymer binder and / or
  • first handling unit and the second handling unit interact in such a way that they can carry out a method comprising: producing a first concrete layer and a second Concrete layer with a generative method, preferably with a shotcrete method, in particular by the first handling unit, arranging a positioning element for arranging a reinforcement unit, wherein the positioning element is arranged with a support section between the first concrete layer and the second concrete layer and with a fastening section from the first concrete layer and protrudes from the second concrete layer, in particular with the second handling unit, arranging at least one reinforcement unit for reinforcing the concrete component on the positioning element, in particular with the second handling unit, and preferably creating a concrete cover layer on the first concrete layer and the second concrete layer in such a way that the reinforcement unit in Is essentially covered with concrete, in particular by the first handling unit.
  • the first handling unit can be designed as a first robot and / or the second handling unit can be designed as a second robot.
  • the first robot and / or the second robot can, in particular, be designed as an articulated arm robot. It is particularly preferred that a distal end of the robot or robots is designed to be movable in three spatial directions.
  • the first handling unit and / or the second handling unit preferably each have an active area in which they can carry out a production process, in particular a spraying process, preferably a shotcrete process, and / or a support process with a tool.
  • the manufacturing system comprises a third manufacturing module with a charging unit for the provision of material components, which are in particular additives, preferably powdery, fibrous and / or liquid additives, and / or additives and / or binders, wherein the charging unit preferably comprises a feeding device and a conveying unit and / or a second metering unit.
  • material components which are in particular additives, preferably powdery, fibrous and / or liquid additives, and / or additives and / or binders
  • the charging unit preferably comprises a feeding device and a conveying unit and / or a second metering unit.
  • the aforementioned object is achieved by a method for the generative production of a component, preferably a concrete component, in particular using a spraying method, preferably a shotcrete method, comprising the steps of: providing a first material component, preferably a first concrete component, and a second material component , preferably a second concrete component, in particular on a supply unit of a production system, generating a composite material, preferably a concrete, by mixing the first material component, preferably the first concrete component, and the second material component, preferably the second concrete component, in particular in a mixing unit of the production system, and Generative production of the component with the composite material, preferably the concrete component with the Concrete, preferably by means of a spraying process, further preferably by means of a sprayed concrete process, in particular with a first handling unit.

  • the production system 1 has the third production module 300, which has charging units 302 and a second metering unit 304.
  • the charging units 302 are provided in particular for storing additives, additives and binding agents for the concrete to be produced.
  • the second metering unit 304 coupled to the charging units 302 can measure a weight or a volume or a quantity of the additive or the binding agent and send it to the mixing unit 106 located below as required.
  • these additives and binders are mixed with the concrete components, in particular granules, supplied via the supply modules 102, 104.
  • the production system 1 further comprises a peripheral unit 400.
  • the peripheral unit 400 comprises units for carrying out support processes.
  • the peripheral unit 400 can, for example, have an air pressure unit for providing compressed air.
  • the peripheral unit 400 can comprise a wastewater treatment plant.
  • the peripheral unit 400 has a power unit which is arranged and designed to supply the manufacturing system with electrical power. As a result, the manufacturing system can be operated autonomously and is particularly advantageous for use close to construction sites.

  • the first production module 100 also has a cleaning system 114.
  • the cleaning system 114 is coupled to cleaning nozzles 116 in the mixing unit 106 and to cleaning nozzles 118 in the discharge funnel 108 and the pump unit 110. These are also coupled to a fresh water line 129.
  • the mixing unit 106, the discharge funnel 108 and the pump unit 110 are cleaned by the fluid, in particular water, emerging from the cleaning nozzles 116, 118. This cleaning is used in particular when there is essentially no concrete to be processed in these units.
  • the water contaminated with cleaning particles, in particular concrete residues, is disposed of via a waste water valve 120 and a waste water pump 122. Disposal takes place via a gray water pipe 126 which passes through a water treatment system 124. From the water treatment 124, the purified water reaches the cleaning system 114 again via a white water line 128. From the cleaning system 114, the water can get back into the cleaning circuit described above.
