Definitions

  • the present invention relates to a mixing head with an integrated shot counter.
  • a metering and mixing device for liquids with supply circuits for each liquid each supply circuit comprising a container and a metering device connected to the container.
  • a valve means is provided between each container and the associated metering device, which liquid can lead back into or out of a container.
  • a mixing head receives the various fluids through the valves.
  • the metering devices are operated synchronously and the valve means are synchronous with each other and adjustable to the operation of the metering devices.
  • EP 0 753 034 discloses an apparatus for mixing and dispensing reactive fluids wherein feedstock from various sources is supplied via valve means and injectors to a mixing head which can provide a continuous stream of reaction material. Similar to the previous one GB 1 305 630 Means are provided to synchronize the operation of the valve means with the movement of the mixing head, so that the reaction mixture can be continuously introduced into a mold.
  • mixing heads for example, for the polyurethane processing, it is known to determine the number of material discharges, which usually corresponds to the number of parts produced.
  • a material discharge for a part is commonly referred to as a "shot”.
  • the warranty periods for the mixing heads usually refer to the number of such shots.
  • the opening and closing operation of the mixing head (for example, the operation of a control or cleaning piston) is detected and transmitted to an external controller. Via a counter in the external control, the total number of shots for a mixing head is then detected and stored in a memory of the external control.
  • the disadvantage here is that there is no direct assignment of the meter reading information to a mixing head. This is particularly problematic when a customer exchanges a mixing head. In this case, he would also have to determine the current meter reading from the external controller and assign it to the removed mixing head. Only then is the actual load of the mixing head known by the number of shots. When it comes to warranty cases, the manufacturers of such mixing heads rely on the honesty and reliability of the customers. But even with reliable customers, it is always a problem that a used mixing head the scope of use, ie the number of shots, can not always be properly assigned.
  • Object of the present invention is therefore to provide a mixing head according to claim 1, wherein the o. Problems can be avoided.
  • a shot counter with a non-volatile memory in the mixing head in particular in the mechanics of the mixing head, is integrated.
  • means are provided to determine the operation of the mixing head, for example, the movement of a control or cleaning piston and pass it on to an electrical detection and storage device.
  • the electrical detection and storage device has a counter that counts the number of shots and this information in a non-volatile storage medium or storage medium stores.
  • a sensor is provided as means for determining the operation of a mixing head, for example for determining the movement of the control or cleaning piston.
  • an electrical or hydraulic signal for the mixing head can be evaluated.
  • the means may also be current, voltage or pressure sensors. But other investigative possibilities are conceivable.
  • a particularly preferred embodiment of a sensor is a switch, for example a reed switch. Such a switch can be arranged in the region of the cylinder cover of a mixing head or a housing for the control or cleaning piston.
  • an interface for producing a communication connection is preferably provided. So that no manipulation can be made, the electrical detection and storage device is designed such that the storage means can only be read externally (read-only counter). Thus, no writing or overwriting of the memory contents is possible.
  • a separate power supply is provided with a battery in the mixing head, which serves for the operation of the electrical detection and storage device and / or for buffering the storage means.
  • a lithium battery can buffer up to 30 years.
  • the electrical detection and storage device firmly integrated into the housing of the mixing head, in particular poured (eg in a cylinder cover of the control or cleaning piston), so the unit can not be removed without damage and thus not easily manipulated.
  • Another measure to prevent manipulation is the assignment of a unique, the mixing head identifying Information, in the aforementioned or another storage means. For example, a manufacturer-unique identification number can be burned into the counter.
  • the storage of further information in the storage means or an additional storage means is readily possible. For example, in such a memory it is possible to store, for example, short textual information containing a cv reference for the mixing head. Thus, individual data for repairs and associated counter readings can be stored. With this procedure, it is possible to document the history of a mixing head without any gaps.
  • the cylinder cover 10 shown in the figures has a recess in the upper region, in which a circuit board 12 is arranged.
  • the circuit board 12 is provided with an integrated circuit 14 (IC) having a counter and a memory.
  • IC integrated circuit
  • the board 12 is embedded inextricably in the recess. Via wire contacts, the circuit board 12 is connected to a separate Ansteckbuchse 16, which acts as an interface to an external controller. Through this interface, the external controller can be connected to the present electronic detection and storage device.
  • the board is also connected to a reed switch 22, which is arranged in a dip tube 20 and cooperates with an underlying magnet 24.
  • the dip tube 20 is directed in the direction of the control and cleaning piston, not shown.
  • the cylinder cover 10 is placed on the housing of a control and cleaning piston, wherein the housing of the control and cleaning piston in Fig. 2 would connect below.
  • control and cleaning piston If the control and cleaning piston, not shown, actuated by a hydraulic system, it moves between an upper and a lower position. In the lower position, the mixing head is closed and there is no discharge. In the upper position of the mixing head is open and there is a discharge. Thus every movement from bottom to top indicates a shot (material discharge). The movement of the control and cleaning piston and thus the initiation of a shot is detected by the reed switch 22. A corresponding signal is forwarded to the integrated circuit 14. The integrated circuit in the 14th integrated counter increases the number of shots by one with each shot and stores this value in the integrated memory.
  • a 64-bit long identification number is included in the memory of the integrated circuit 14, which allows a unique assignment of the counter to the serial number of the mixing head.
  • a shot counter with a non-volatile memory is integrated in the mechanics of the mixing head, which only allows read access.
  • each counting pulse is also processed in the integrated circuit 14 and assigned directly to the mixing head. If a mixing head is to be repaired, the meter reading can be read out via an interface, for example a serial interface, thus determining the scope of use.
  • the memory in this case has its own memory area in which short text files can be stored.
  • Information about the curriculum vitae of the mixing head is incorporated in these text files, namely the data of individual repairs and the corresponding meter readings.
