Definitions

  • the object of the invention relates to a device for packaging, in particular on a vertical form, fill and seal machine with a funnel for filling a Filling material into a vertically aligned filling tube, a vertically aligned filling tube, a shape shoulder on the filling tube for forming a film web into one Foil tube, the foil tube surrounding the filling tube, an air outlet nozzle on the funnel and one connected to the air outlet nozzle via a feed line Device for generating an air flow to one in the funnel and in the filling tube Generate airflow that the filling material through the funnel and the filling tube in allows the film tube to pass, as is the case without using an air stream would.
  • Such a device is known from DE-OS 0 192 604.
  • At this Device is a variety of lobe-shaped air nozzles in the funnel wall or the filling pipe is provided for a downward air flow in the filling pipe generate to drop a filling material faster than with the natural gravitational acceleration to let.
  • DE-OS 33 25 300 Another device of this type is known from DE-OS 33 25 300. At this An annular gap below the funnel is used to feed a device accelerating air flow.
  • the known devices have the disadvantage that they become uncontrolled Inflate the lower area of the film tube to be filled and thus the result in the tubular bag generated.
  • the invention is based on the object of a device at the outset to further develop the described type in such a way that it can be carried out reliably Tubular bags can be manufactured with a certain constant internal pressure can.
  • the problem is solved according to the characterizing part of claim 1. After that a measuring device for measuring in the lower region of the film tube prevailing pressure is provided, and the measuring device is equipped with a Measured value indicator connected.
  • the invention has the advantage that in the lower region of the film tube and so that the pressure prevailing in the tubular bag to be produced is displayed. Consequently the strength of the air flow can be adjusted so that a certain pressure is achieved. In the event of a deviation from this internal pressure, the air flow changed to keep the pressure value constant.
  • the Measuring device analogous to claim 2 contains an open end of a tube, the tube is guided through the form shoulder, and the measured value indicator outside the Foil tube is provided.
  • the pipe transmits the lower part of the Foil tube prevailing pressure on a measuring device, which z. B. outside of the film tube, and its measured value is displayed by the measured value indicator becomes. Based on the measured value display, the air flow can be done manually or by means of a Control unit can be adjusted.
  • the fact that the tube through the interior of Form shoulder is carried out, there is no impairment in the hose production.
  • the measured value transmission can be carried out wirelessly without any interference with the Packing device take place when the measuring device has a measured value transmitter contains, and a measurement receiver is provided outside the film tube, which is connected to the measured value indicator (claim 3).
  • a downward air outlet nozzle in the passage between the funnel and the filling tube has the advantage that conventional funnels and filling tubes can be used to introduce the air flow into the filling tube.
  • the Air outlet nozzle is provided where the funnel somewhat removed from the filling pipe is one Gap created.
  • the air outlet nozzle provides airflow down and causes a negative pressure on the funnel so that a filling material passes the funnel faster. On Airflow directed downwards from the air nozzle accelerates the filling material during his free fall additionally.
  • the air flow accelerating the filling material is further improved, if in addition a suction device is provided for the air outlet nozzle.
  • a suction device is provided for the air outlet nozzle.
  • the film tube is picked up by the format tube and slides on it along.
  • the air flow in advantageously be set such that a certain excess pressure, for. B. for a certain bag size and a certain filling material is provided.
  • a certain excess pressure for. B. for a certain bag size and a certain filling material is provided.
  • the control unit that also controls the air flow depending on the power controls the packaging machine, an advantage.
  • a bulging with air offers Bags protect the contents from damage to the contents.
  • the Control device connected to the measured value indicator (claim 8), so the Control device depending on the measured internal pressure this constant hold.
  • a technical simplification of the device is given if analogous to claim 8 the device for generating an air flow also as a suction device is provided. Then a flow circuit for the air is largely achieved.
  • the air flow continues improved and the fall speed can be increased further, e.g. B. by a greater or more accurate air flow.
  • the additional air outlet nozzle can be be provided in the filling tube or on the inner wall of the filling tube (claim 11).
  • the producible The air outlet nozzle is then pushed apart slightly by a funnel and filling tube generated and by pushing the funnel and filling tube together eliminated again.
  • the size and thus the performance of the nozzle can be changed if the Funnel or the filling tube is adjustable in height so that the air outlet nozzle is narrower or can be set wider (claim 13).
  • Using a simple Height adjustment device can thus be based on the air flow or the falling behavior of the Fill goods are influenced. This height adjustment can be done with the control of the air flow are taken into account.
  • a funnel 2 is used to fill in a a metering device 3 and a timing hopper 4 dropped contents in a Filling tube 5.
  • the filling tube 5 is aligned vertically and part of a vertical Tubular bag machine.
  • a shape shoulder 6 is used to form a flat film web 24 into one Foil tube 22, which is received by a format tube 7, and in one Filling should take place.
  • an air outlet nozzle 8 which is connected via a feed line 9 from a Device 10 for generating an air flow is supplied with compressed air.
  • the Air flow is directed downwards in the filling pipe 5 in order to get the filling material through the pipe faster Funnel 2 and the filling tube 5 to be conveyed into the film tube, as in one free fall occurs.
  • the air outlet nozzle 8 is in a passage 11 between the funnel 2 and the Filling tube 5 provided.
  • the air outlet nozzle 8 is a circumferential gap 12 on which an annular circumferential pressure chamber 13 surrounding the funnel 2 connects.
  • the Filling tube 5 is surrounded concentrically by the format tube 7 open at the bottom.
  • a line 17 connected to the device 10, which is also used as a suction device 15 for the bottom air stream emerging from the filling tube 5 is used.
  • a control unit 16 on the Device 10 is a certain excess pressure in the filling tube 5 and thus in bag to be produced.
  • two further air outlet nozzles 18 are provided, which are supplied by a separate compressed air generator, and which on the inner wall 19th the filling tube 5 are provided.
  • the funnel 2 can be adjusted in height by means of a height adjustment device 20 such that the air outlet nozzle 8 can be generated and set narrower or wider.
  • a portion of filling is first transferred from the metering device 3 to the timing hopper 4 submitted. This throws the contents into the filling tube 5 at exactly the right time.
  • the device 10 supplies the pressure chamber 13 permanently with compressed air, so that the air outlet nozzles 8, 18th maintain a permanent air flow down in the fill tube 5. It could but also generates a pulsed air flow with a device according to the invention become.
  • the air flow passes from the filling pipe 5 at the lower end 21 of the filling pipe 5 out. There the filling material accelerated downwards by the air flow is brought into the film tube 22 welded down is thrown off.
  • the airflow arrives through the intermediate space 14, the cover 23 and the line 17 to the device 10, which is a blower 25.
  • a measuring device 26 for measuring that in the lower region of the film tube 22 prevailing pressure P is provided.
  • the measuring device 26 is with a Measured value indicator 27 connected.
  • the measuring device 26 consists of a measuring device 28 and one with the measuring device 28 connected hollow tube 29.
  • the open end 30 of the tube 29 protrudes into the lower region of the film tube 22 and transmits the pressure prevailing there to the measuring device 28.
  • the tube 29 passes through the shape shoulder 6 from the Foil tube 22 out.
