Definitions

  • Container for carrying out the method and rolling bearing with a
  • the invention is in the field of mechanical engineering and electrical engineering and relates in particular to the marking of components.
  • the individualization and corresponding marking of components is an important aspect during the production process and also during maintenance. Due to a labeling individual components can be assigned to specific production batches and thus can be subject to errors occurring the entire batch of immediate maintenance or even replacement, as far as the individual components can be tracked. In the production process, it can be important to label each individual component with information that identifies the production steps that have already been carried out or the parameters that have occurred. Also dimensions or other properties of the components can be added to a corresponding marking. In addition, information about the production time often occurs in order to later be able to relate the age and the state of wear of components to one another.
  • RFID Radio Frequency Identification
  • transponders are possibly limited range in the vicinity of metallic objects, which makes it difficult, for example, to respond as bulk material present components, which themselves consist of metal, or even those components that are located in a metallic container.
  • DE 102005043773 A1 discloses a warehouse with an RFID device which receives and stores storage data and makes the corresponding data available later.
  • the data is used to optimize maintenance and includes, for example, operating parameters and information about particular load conditions that the warehouse has undergone.
  • the present invention is based on the object of providing a method with which a group of components, each having a transponder and a memory device, can be identified as efficiently as possible.
  • the object with the features of claim 1 of the method according to the invention and by a group of components according to claim 13 is achieved.
  • the invention also relates to a container according to claim 14 and to a roller bearing according to claim 15.
  • the invention is based on the problem that several components, which are unmarked as a group of components, should be identified as efficiently and individualized, the cost of time and costs should be minimized.
  • the invention achieves this object by a method in which a first marked component comes into contact with second components arranged within its reach, transmits this information to the latter, each of which characterizes itself taking into account the information transmitted by the first component, and wherein at least one second Component according to its identification to other, not yet marked components within its reach in contact occurs to effect their identification.
  • This method assumes that there is at least one component that responds to a subsequent generation of components and requests them by a corresponding signal to identify themselves.
  • the second components belong to a generation that follows the generation of the first component.
  • the generation is therefore a first parameter that distinguishes the first component from the second component.
  • the second components must now find corresponding self-identifications using the information they have received from the first component. For this they can either individually individually communicate with each other with the first component, which then manages the necessary different identifications of the second components or the second components can communicate with each other to avoid identically denominated markings.
  • each component can be provided with an algorithm that results in the other components of the same generation reporting and logging in their identification. The component that does this first is accepted by the others and may first be identified.
  • the first component assigns the corresponding identifications to the components of the second generation, for example by assigning the generation number and numbering it.
  • a possible marking parameter is thus the designation of the generation of the respective component, that is to say the designation of the number of marking runs already carried out up to its marking.
  • a tagging parameter can exist in a time stamp, which, for example, designates the time of the tagging.
  • the first component can advantageously capture and store the identification data of the second components. This can apply in the following for each component with regard to the components of the following generation which it has addressed.
  • every second component detects and stores all identification data of the remaining second components. This can also apply to each subsequent generation, so that a component of a generation can capture and store the identification data of all other components of the same generation and advantageously also of the other generations.
  • each unmarked component before its identification only communicates with the component already identified, which first comes into contact with it.
  • the already marked components are clearly identifiable, the still unmarked components in their communication can clearly specify with which of the already marked components that have come in contact with them, they want to communicate to determine their own labeling.
  • the described method is repeated in successive generations until all the components have been addressed, wherein, for example, a container filled with corresponding components is gradually penetrated depending on the range of the communication.
  • the range of the communication can be determined, for example, by the transmission strength or the reception sensitivity of the transponder.
  • the transmission strength and / or the reception sensitivity may be adjustable in the transponders in order to improve the orderly course of the method.
  • the communication between the transponders is advantageously time-synchronized (eg TDMA: Time Division Multiple Access). Cyclic communication avoids collisions.
  • the frequency spread and the frequency hopping method can be used. The reliability of the transmission can be increased in the network.
  • the labeling process is advantageous from a separate transmitting and receiving unit or by a transponder, the z. B. has the function as a gateway, which is associated with a container containing the components and which comes to the, still untagged, components of the group in contact, which then form the first generation of marked components.
  • the information which the respective components collect about their identifications or the labels of the following generations can also be collected in the transponder or the memory device associated with the container.
  • each component via its transponder detects the markings of the components contacted by it, stores them and passes them on to the component from which it was contacted even before its identification.
  • each component has a plurality of transponders assigned to each of its component elements, the transponder associated with the respective identical component elements belonging to separate classes.
  • the different bearing elements each have a transponder and a memory device be assigned, so that the individual bearing elements such as inner ring, outer ring, end shields, seal, cage and rolling elements each carry the information about their own manufacturing conditions and / or the hours of operation and operating conditions ,
  • This information can be advantageously accumulated in a transponder of the camp, which then corresponds to the assembly of the camp with the transponders of other camps in the context of the method according to the invention.
  • the transponders can also be organized according to each separate classes, so that, for example, all transponders of outer rings of the bearings communicate with each other and the corresponding transponder of inner rings or end shields and so on.
  • the invention also relates to a group of components with transponders and memory devices, each of the components has stored in its memory device its own identification and information about the labels of all other components of the group and a container for carrying out the method according to the invention, wherein the Container has an impermeable envelope for the communication of the transponder and the container is associated with a transponder and a memory device.
  • the invention also relates to a rolling bearing with at least one transponder and a memory device, wherein the memory device includes an individual identifier, which is generated by the inventive method.
  • a self-diagnosis can also be carried out via the main transponder by centrally storing information about the subordinate transponder or the corresponding components and comparing it with later acquired data.

  • a transponder can receive and transmit signals. If it is an RFID transponder, so-called air interface in the radio frequency range using electromagnetic waves is provided. However, other radio signals for information transmission are also conceivable. In principle, other non-wired signals for realizing the method according to the invention are conceivable, such as, for example, infrared or ultrasonic waves. If it is to be determined which components are present in the container 1 or which container is involved, a request signal can be sent into the container 1 by a transmitting and receiving unit 10 and a response can be waited for. If the individual components 2, 3, 4, 5 or the transponder 21 contain markings, they can identify themselves to the request of the transmitting and receiving unit 10 and send back corresponding signals.
  • the components 11, 12 lying further down in the container do not receive the request signal of the transmitting and receiving unit 10, since they are electromagnetically shielded by the components lying above them. Accordingly, it is difficult to determine by a query process which components are stored in the container as a whole.

  • the components come into contact with each other, that is, because of the limited range of the transponder occurs every single component to the other components in contact, which can reach it via its transponder.

  • the component receives the information that it is the first identified component and stores this information as part of the self-identification. It is thus identified as component 1 Generation 1.
  • the component 2 transmits, within the range of its transponder, a second initialization pulse, which is received by the components 3, 4, 5, 13.
  • the individual components 3, 4, 5 13 are numbered according to a fixed algorithm, which can take into account, for example, in which order the components have received the second initialization pulse from the component 2 or in which order they have acknowledged this.
  • each of the components 3, 4, 5, 13 has stored the number of its generation, namely the number 2, as well as a serial number and a time stamp. These quantities are additionally sent to the component 2 and exchanged among the components 3, 4, 5, 13. Thus, all components of the first and second generation now have information about the identity of the already marked components.
  • Each of the components 3, 4, 5, 13 in turn sends a third initialization pulse to the potential third generation components. For identification, these are given the number 3 as the number of the generation as well as, for example, the identity of the component that contacted them and a time stamp. This information is also communicated both within a generation and to the superordinate generations, so that at the end of the described iterative process all components in the container 1 contain the information about all components.
