  • the invention relates to an arrangement for performing this method, with at least one filling element, which one, in an outlet opening, e.g. Filling tube, for the delivery of the filling material opening to the container and communicating with a chamber for the filling material liquid channel, in which a controllable by a signal, preferably by an electrical or pneumatic signal, is arranged a filling valve.

  • these filling tubes are not only expensive, but also very sensitive, i.e. they have to be handled carefully in practical operation and stored gently when not in use, which is rarely guaranteed in practice.
  • the filling process can be optimized by filling a bottle or a container initially, i.e. For example, up to a partial filling quantity of, for example, 10% of the total filling quantity, at a low speed and then subsequently up to a larger partial filling quantity of, for example, 85% of the total filling quantity at a much higher speed, whereupon the filling speed then follows until the desired total filling quantity is reached is reduced again.
  • the invention has for its object to provide a method and an arrangement for controlling a filling machine of the type described in such a way that, regardless of external influences, the filling process is ended when the quantity of product flowing into a container actually corresponds to the desired total quantity, whereby external influences on the metered delivery of the liquid contents to a container as far as possible and, above all, there is also the possibility of changing the desired total filling quantity if necessary without complex conversion or retrofitting work.

  • the first setpoint signal which is set, for example, with the aid of one or more switches or in another suitable manner and is preferably in the form of a digital signal, can be changed without difficulty and, above all, without mechanical changes to the filling machine, so that filling of bottles of different sizes is possible with one and the same machine without difficulty.
  • the method of the invention offers the possibility, in addition to the first target value signal, which corresponds to the angstrebten total filling amount or the desired End StirllMap to provide another set point signal corresponding to a pre g plane part-filled state of the container, wherein when the actual value of this further Setpoint signal reached has, a further control signal is generated, which switches from the partial or measuring phase with slow filling speed to a partial or measuring phase with high speed or vice versa.
  • the method according to the invention is also particularly suitable for controlling counterpressure filling machines in which, during the filling process, the actual filling phase is preceded by a pretensioning phase in which the containers or bottles to be filled are pressurized with a pressurized gas.

This point in time does not necessarily coincide with the point in time at which the filling element 3 in question has reached position III of FIG. the time II / 3 lies between positions II and III.
  • the signal transmitter 68 supplies a signal to the OR gate 64, the output signal of which in any case leads to the valve body 24 being closed, even if a corresponding closing Signal at the output of the comparison circuit 54 should not yet be present.
  • the level of the counter 51 is reset to zero before the start of each new filling phase. This can be achieved, for example, by supplying a reset signal, preferably with a time delay, to the counter 51 for a signal at the output of the OR gate 64.
  • the signal applied to signal line 62, for example, with which the entire filling process (consisting of pretensioning phase and filling phase) is initiated can also be used to reset counter 51.
  • control device shown in FIG. 6 is basically present separately for each filling element 3 on the rotor 1. However, it has already been pointed out that certain parts of this control device can be used together for several filling elements 3 or groups thereof.
  • FIG. 7 shows a further development of the control device according to FIG. 6 in such a way that a common central unit 88 is provided on the rotor 1 for several filling elements 3 or for groups of these filling elements.
  • This central unit is connected via lines 89 to control devices 90, each of which is assigned to a filling element 3 and which, for example, correspond in its basic design to the control device according to FIG. 6.
  • the central unit 88 has an output which is connected to a transmitter 91 and an input which is connected to a receiver 92.
  • An operating device 93 is provided on a stationary part of the filling machine, the input of which is connected to a receiver 94 and the output of which is connected to a transmitter 95.
  • the operating device 93 also has an input device 96 and an output device 97.
  • the central unit 88 and the operating device 93 work together via the transmitter 95 and the receiver 92 or via the transmitter 91 and the receiver 94, the data transmission here being able to take place in a wide variety of ways , for example by electromagnetic waves, by infrared light, etc.
  • Various data or commands can be transmitted to the central unit 88 via the input device 96, for example the input of the desired values as described in connection with FIG. 6 and in connection with the elements 56, 57, 58 and 59.
  • individual valves of individual filling elements 3 or groups thereof can also be addressed or controlled via the input device 96.
  • Setpoints, filling success messages, counter status of the individual filling valves or the associated counters can also be queried via the input device, these data then being output on the output device 97.
  • the output device 97 can also serve to display errors, in particular to display defective filling elements 3, or else to display the quantity of filling material actually filled in bottles
  • FIG. 8 shows an embodiment similar to FIGS. 2 and 3, although a liquid channel 14 'is provided instead of the horizontal liquid channel 14, which also extends through the signal transmitter 41, but in the flow direction of the filling material (arrow F of FIG. 8 ) is inclined downwards by an angle a with respect to the horizontal, so that the outlet end of the channel 14 'connected to the filling element 3 is lower than the inlet end connected to the chamber 1.
  • the angle a is, for example, 5 °.
  • the signal generator 41 has the same design as that shown in FIG. 4.
  • the embodiment of the embodiment shown in FIG. 3 is designed such that an area of the liquid channel or a flow path for the filling material, in which none of these are connected, to the signal transmitter 41 or to its measuring sections formed between the electrons 46 and 47 Filling-reflecting surfaces are provided, which are formed, for example, by narrowing the cross-section and / or by elements extending into the flow path.
  • the length L of this flow path is approximately equal to 5 D, where D is the diameter that the liquid channel 14 'has in the area of the electrodes 46 and 47 or the pipe section 42 in this area.
  • the flow path free of reflection surfaces preferably has a constant cross section equal to cross section D.
  • the inclined design of the liquid channel 14 'and the flow paths free of reflection surfaces ensure that there is a flow in the area of the signal transmitter 41 only in the direction of the arrow F, that is to say there is no partial reverse flow direction which could lead to an incorrect measurement . Furthermore, due to the inclined design of the liquid channel 14 ', air or gas bubbles can escape from the channel 14' or from the interior 18.
