Definitions

  • the invention relates to a tubular bag machine with Dosiervorrich device, as used for the packaging of products.
  • the tubular bag machine is designed in the manner of a double tube tubular bag machine and is therefore equipped with two longitudinal welding devices for forming two parallel film tubes. These two film tubes are each transversely sealed in the tubular bag machine by means of two cross sealing jaws that can move against each other and weld the film tube transversely, so that two strands of tubular bags can be produced continuously or intermittently.
  • the tubular bags are filled with the filling material by means of a filling device in each case.
  • the individual tubular bags are separated from one another by means of a separating device.
  • a metering device is arranged upstream of the filling device.
  • the dosing device In the dosing device, portions of the filling material are separated in each case in order to fill the two filling devices of the double-tube tubular bag machine with the specified quantities, for example a specified filling weight, a specified filling volume or a specified filling number.
  • the dosing device works synchronously with the tubular bag machine so that the filling device can fill in the amount of the filling material necessary for filling the tubular bag at the exact time required. This synchronous mode of operation between the dosing device and the tubular bag machine leads to increasing problems.
  • a first disadvantage of the synchronous operation between the dosing device and the tubular bag machine is that every small process disturbance during the dosing in the dosing device leads to a standstill or to an idle cycle in the double tube tubular bag machine. Particularly in the case of high-performance tubular bag machines with an output of more than 400 tubular bags per minute, the synchronization between the tubular bag machine and the metering device can only be guaranteed with great effort. In order to provide the necessary dosing capacity, high-performance dosing devices have to be used, but these are very expensive and require a lot of maintenance.
  • Another disadvantage of the synchronous operation between the tubular bag machine and the dosing device is that the dosing device has to be arranged above the filling device for this according to the known prior art. Since the metering device to maintain the necessary metering capacity requires an ever larger installation space, this results in an ever higher room height, which is required for the installation of the tubular bag machine with the metering device arranged above it. Based on this prior art, it is therefore the object of the present invention to propose a new double-tube tubular bag machine which avoids the disadvantages of the previously known prior art.
  • the double tube tubular bag machine according to the invention is based on the basic idea that a transfer device with several transfer containers is provided between the two filling devices of the double tube tubular bag machine and the dosing device. In other words, this means that the required filling quantity of the filling material is no longer metered directly by dispensing the filling material from the metering device into the two filling devices of the tubular bag machine.
  • the transfer device comprises an input station in which the specified fill quantities for each filling of the individual tubular bags from the dosing device are transferred to a transfer container in each case. The transfer containers are then transported along a transfer line to two delivery stations.
  • the transfer containers are then emptied in the delivery stations and the filling material is transferred from the transfer containers to the two filling devices of the tubular bag machine.
  • the transfer container then arrives back to the input station along a return path and can there be refilled from the dosing device.
  • the dosing process is decoupled from the tubular bag filling process by the transfer device, so that the dosing device and the tubular bag machine no longer necessarily have to be operated in synchronous operation.
  • This decoupling makes it possible, in particular, that disturbances in one of the two processes do not directly cause disturbance in the other process.
  • the transfer device makes it possible to use the dosing device also to make locally inde pendent of the arrangement on the tubular bag machine, so that an arrangement of the metering device above the filling device of the tubular bag machine is not absolutely necessary.
  • the invention also enables the product drop height to be reduced and the performance of the process to be increased.
  • Product protection for fragile products is also increased.
  • Transfer containers with a non-constant diameter can be used to increase the emptying speed. By decoupling the dosing and bag filling process, the speed of the filling process can be increased through optimized speed controls and improved opening procedures.
  • the distance between the two delivery stations can be changed.
  • the geometry of the delivery stations can be adapted to the variable geometry of the double-tube tubular bag machine.
  • this can be compensated for by changing the distance between the two dispensing stations.
  • Which type of tubular bag machine is combined with the transfer device is basically arbitrary.
  • the arrangement of the transfer device between the dosing device and the tubular bag machine offers particularly great advantages in those cases in which a vertical double tube tubular bag machine is used.
  • the structural design of the filling device is in turn basically arbitrary.
  • the filling device is designed in the manner of a format tube, the film tube being guided on the outside of the format tube. Through the inner cross-section of the format tube, the filling material can then be filled into the open tubular bag from above under the influence of gravity.
  • the dosing device to be used in each case. In principle, all gravimetric or volumetric metering devices or metering devices that work with a counting method can be used. Depending on the way in which the metering takes place, either a scale or a screw conveyor or a counter or a Volumendosiereinrich device can be used as the metering device.
  • the transfer device is controlled by its own transfer controller.
  • This transfer control can control the transfer process in the input station independently of the transfer process in the delivery station, so that a real decoupling between the two processes is guaranteed.
  • the transfer control can change the conveying speed of the transfer containers along the transfer path and / or along the return transfer path. Through such speed variations, in particular smaller delays in the area of the dosing can be compensated for without any problems in order to ensure the timely delivery of the pre-dosed quantity of the filling material in the delivery station even if minor process disturbances occur.
  • the transfer control can change the conveying speed of individual transfer containers independently of the conveying speed of the other transfer containers.
  • the transfer device can be equipped with at least one buffer. At least one filled or unfilled transfer container can be temporarily stored in this buffer. If there is a minor process disruption, for example the prevents timely filling of a transfer container, the transfer container temporarily stored in the buffer can be removed and introduced into the transfer path or the return transfer path. In particular, it can be advantageous to provide a buffer in front of each delivery station.
  • a dosing device is connected to a double tube tubular bag machine by means of the transfer device.
  • the transfer device comprises at least two input stations, at each of which filling material can be transferred from a metering device to the transfer container.
  • the necessary dosing capacity is distributed over several dosing devices so that, for example, a high-performance double-tube tubular bag machine can be supplied with the pre-dosed filling quantities from two or more dosing devices.
  • the individual metering devices can then each have a correspondingly lower metering rate, so that no high-performance metering devices have to be used, in particular for metering on high-performance double-tube tubular bag machines.
  • the dosing of the filling material by means of several dosing devices and their transfer to at least two different input stations in the transfer container is particularly of great advantage when the tubular bags are to be filled with a mixed filling, for example a mixture of nuts.
  • a mixed filling for example a mixture of nuts.
  • different filling goods can be filled into the transfer containers at the different input stations, whereby the individual transfer containers then contain the correspondingly desired mixture of the filling goods when they reach the delivery station.
  • the individual metering of the partial components resulting in the mixture also increases the metering accuracy of the proportions of the partial components in the mixture.
  • the transfer device can also comprise more than one pairing of two delivery stations. At each pair of two dispensing stations, the filling material or the mixed material can then be transferred from the transfer containers to the filling devices of different double-pipe
  • Tubular bag machine Using appropriate transfer devices, complex transfer systems can also be formed in this way, in which a large number of possibly different metering devices are linked to a large number of different tubular bag machines, so that an optimized
