Definitions

  • the present invention relates to a device for displaying information stored in a transponder about at least one item to be transported and / or processed.
  • Transponders are passive components that are used to identify goods to be processed and / or transported. Each transponder is either attached to the good itself or to a container containing the good. Information is stored or contained in the transponders which can be read out and / or updated by appropriate transponder read / write devices.
  • a transponder is usually permanently assigned to each container or item. In the production of silicon wafers that are transposed in plastic containers, the respective transponder can be welded into the respective plastic container, for example.
  • the transponder read / write devices are arranged in the transport chain or processing chain for the goods at transport stations or processing stations.
  • the transponder read / write device recognizes an approaching transponder, reads the identification information from it and uses it to control the further transport or to control the processing step by the corresponding machine.
  • the transponder read / write devices arranged stationary at the processing positions or transport positions can be connected to one another in order to monitor and control the transport and processing steps.
  • the corresponding transponder read / write device can write updated information into the transponder, for example with the content that the corresponding processing step has been carried out on the assigned good.
  • a disadvantage of the system for controlling and monitoring the transport or processing of goods by means of transponders and transponder read / write devices explained above is that the information contained in the individual transponders is not accessible while the goods or those containing the goods Containers can be transported from one station to the next. The operating personnel cannot easily judge from outside the process stage in which the goods are.
  • a further disadvantage is that the processing or transport sequence, ie the sequence of the processing stations to be started by each item to be processed, is no longer changed once the process has been defined and started. If a processing station, ie a processing machine or the like, fails, the transponders on the goods or the containers of the goods which are to be transported to this processing point can no longer be diverted, since the information contained in the transponders is not changed during the transport can. This is problematic, for example, in the production of silicon wafers, since the production quality of these is sensitive to the time it takes to pass through the individual processing stations.
  • a further disadvantage of the known system is that individual goods or containers carrying transponders cannot be sought. If a good or a container is lost, i.e. is outside the range of the transponder read / write devices, it is not possible to find the goods or the container again.
  • the transmission power of the transponder read / write devices is limited by corresponding DIN regulations, since the transponder read / write devices read out the information in the transponders in the radio frequency range, the field strengths per square meter are too strong , so that only an application with a short range (1-2 m) is possible.
  • no transponder read / write devices that have such a high transmission power that all the transponders located in a production hall can be addressed may be used.
  • the transponders should be as small as possible and not have their own power supply, so that the above disadvantages cannot be satisfactorily remedied by the known technology.
  • the object of the present invention is therefore to provide a device which makes it possible to check information stored in a transponder about at least one item to be transported and / or processed at any time and also to detect goods carrying transponders or containers carrying and containing transponders.
  • a device for displaying information stored in a transponder about at least one item to be transported and / or processed with a readout device for reading out the information from the transponder, a display device for displaying the readout information and a transmission device for transmission of information read from the transponder to a transmitting / receiving station, the device being designed to be arranged on the good or on a container containing the good.
  • the information stored in the transponder can be read out and displayed at any time, even if no transponder read / write device is nearby. This enables the operating personnel to check at which stage of the process the goods are at any time.
  • the transmission device for transmitting information read from the transponder to a transceiver station makes it possible to read out transponders during transport or out of the reach of the transponder write / read devices and to monitor, find or check the corresponding goods or containers.
  • the present invention thus enables seamless monitoring.
  • the present invention enables the information in the transponders to be rewritten during transport, so that, for example in the event of a traffic jam, the goods or containers can be diverted and fed to other processing stations.
  • the transmitting / receiving stations to which information is transmitted by the transmission devices of the devices according to the invention, have a greater range than the known transponder read / write devices, namely, for example, 10 to 20 m, so that a larger area can be monitored.
  • Transmit / receive stations can be provided which are networked with one another and monitor essentially every point in the room. Since several broadcast

  • the device according to the invention advantageously also has a device for receiving information from a transmitting / receiving station. If a device is also provided for writing information into the transponder, information stored in the transponder can be supplemented or changed by data received from the transmitting / receiving station.

  • the transmission device advantageously transmits the information to the transmitting / receiving station by means of infrared radiation.
  • infrared radiation In contrast to the transmission in radio frequencies, which is used between the transponders and the transponder read / write devices, transmission by means of infrared radiation allows a greater range since the radiation energy is significantly lower. However, since infrared transmission requires a line of sight, it is more favorable in certain applications to use radio transmission between the transceiver stations and the display device according to the invention.
