Definitions

  • the invention relates to a thermoforming packaging machine according to the preamble of claim 1 and to a method having the features of claim 6.
  • a foil punch which is suitable to cut plastic films by means of a knife and a counter knife.
  • a linear actuator is provided with a linear actuator; and by means of an articulated lever arrangement in conjunction with a stretch lever arrangement, which together comprise a plurality of mechanical levers, it is achieved that effective forces can rapidly increase for cutting the film and the flattening of the forces at the end of the punching stroke.
  • the advantage here is that the film punch is to be suitable to be able to cut different thicknesses of films reliably, without the need for complicated adjustment of the knife are necessary.
  • a foil punch type FS 08 from the house of the applicant (see Fig. 1 ), which has a pneumatic cylinder as a hoist drive and cuts through a film web by means of crushing knife and counter-pressure bar.
  • the counter-pressure bar is designed with a fine adjustment to the back pressure bar to the final position with an accuracy of at least 0.02 mm of the crusher blade.
  • the cutting edge of the crimping knife becomes duller and the counterpressure strip or the crimping knife should be readjusted in order to ensure reliable and qualitatively good cutting of the film.
  • the crushing knife and possibly also the counter-pressure bar are often replaced in format changes and then the counter-pressure bar or the crusher must be readjusted. This is carried out in a first test phase while the thermoforming packaging machine is running and requires a certain amount of effort until the cut or the severing of the film is precisely set.
  • the loading of the crimping knife by the contact with the counter-pressure bar during each cutting or squeezing operation can be very high, as in a time-force diagram according to FIG Fig. 2 shown.
  • pressure measuring sensors in the area of the fine adjustment device were provided in an experimental arrangement in order to detect the load on the counter pressure bar or the crush meter.
  • the diagram shows that after the cutting of the film at time t 2, the force continues to rise, as the pneumatic cylinder with its executable by the applied pressure force presses the crimping knife and the counter-pressure bar against each other.
  • This force F1 is in this case shown by way of example more than twice as high as necessary for the separation process.
  • a fundamental reduction in the compressed air supply of the pneumatic cylinder is not desirable, as with a halving of the pressure, for example, is accompanied by a reduction in the speed of the lifting drive and this reduces the cycle performance of the film punch.
  • the reduced speed at which the crimping knife strikes the film has a negative impact on the quality of cut when the film is cut.
  • Object of the present invention is to improve a thermoforming packaging machine with a foil punch in terms of extending the life of the tools and to facilitate the adjustment of the tools to each other when changing the tools.
  • thermoforming packaging machine with the features of claim 1 or by a method for operating such a thermoforming packaging machine with the features of claim 6.
  • the thermoforming packaging machine comprises a control and a foil punch, which has a lever mechanism, an upper tool part and a lower tool part, wherein at least the upper tool part or the lower tool part are movable by means of the lever mechanism so as to approximate the upper tool part and the lower tool part.
  • the thermoforming packaging machine according to the invention is characterized in that the film die has a servo drive and a measuring unit is provided which is configured to detect the contact between the tool top and the tool bottom. Taking into account this contact position of the movable tool, for example by a calibration process, the for the punching process most suitable end position or end position of the movable tool and thus the position of both tools to each other determined in the controller and approached or positioned in the subsequent punching operations. Due to the exact end position of the movable tool, there is no unnecessarily higher force or load on the crusher.
  • the controller is connected to the measuring unit and the position of the upper tool part and the lower tool part in the working position can be calculated by means of the controller.
  • This supports a fully automated calibration mode.
  • it is optionally also provided to perform the lower position or the open tool position changeable by the operator and to be able to store in programs to reduce unnecessary lifting movements, for example, at low packing depths.
  • the measuring unit is a controller of the servo drive, so that based on a current consumption over time, namely during the calibration movement of the movable tool, the working position can be detected and evaluated. Because at the point where the tools come into contact, the power consumption increases sharply and it can have more characteristic features.
  • the measuring unit is a pressure measuring sensor or a structure-borne sound or vibration measuring sensor in order to detect the pressure force between the upper tool part and the lower tool part.
  • the structure-borne sound or vibration measurement sensor are preferably suitable for detecting the meeting of the two tools by the sudden impact and for detecting the vibration generated thereby.
  • the servo drive comprises a servomotor with regulator and a spindle, preferably a ball screw, in order to position the movable tool at high speed with high accuracy at the same time.
  • a method according to the invention for determining the working position, in particular of the lower die part of the foil punch, is characterized in that the lower tool part and the upper die part are approximated and the contact of the tools is determined by means of an evaluation of data of the measuring unit by means of the control.
  • the measuring unit is a controller for a servomotor of the servo drive and based on the current consumption of the servo motor, the force profile of the force acting on the movable tool is detected.
  • a suitable position namely an end position, can be determined automatically in the controller.
  • the measuring unit is a pressure measuring sensor and there is a force measurement on a tool.
  • the controller calculates an end position for the movable tool, so that during punching no (substantially) higher than the forces necessary for the punching process are generated to extend the life of the tools.
  • Fig. 1 shows in a sectional view of a foil punch 1 according to the prior art with a lever mechanism 2 in order to move a tool lower part 3 vertically upward can.
  • a drive for the lever mechanism 2 is a pneumatic cylinder 4.
  • the lever mechanism 2 transmits the movement of a piston of the pneumatic cylinder 4 on the lower tool part 3.
  • the design of the lever mechanism 2, the stroke and the force of the lower tool part 3 are fixed.
  • the lower tool part 3 is in Fig. 1 shown in its maximum upper position. In this case, a counter-pressure bar 6 of the lower tool part 3 is in contact with a knife 7a of a tool upper part 7.
  • the foil punch 1 setting wheels 8 In order to adjust the compressive force exerted by the counter-pressure bar 6 on the knife 7a, the foil punch 1 setting wheels 8 to the knife 7a with a Accuracy of a few 1/100 millimeters in height and thus to be able to adjust relative to the counter-pressure bar 6 of the tool part 3. Due to the constant contact of the knife 7a on the back pressure bar 6 after cutting through a film, the cutting edge of the blade 7a blunts and the blade 7a has to be adjusted downwards in order to be able to maintain a good punching or cutting result. Incorrect settings can greatly affect the lifetime of the Messer 7a and counterpressure 6 bar.
  • Fig. 2 is the force curve of the pressure force F, which is exerted by the counter-pressure bar 6 on the knife 7a, using a time-force diagram in a solid line on the example of the foil punch 1 from Fig. 1 shown.
  • the lower tool part 3 is in the lower basic position, in which the pneumatic cylinder 4 is fully retracted.
  • the pneumatic cylinder 4 is then pressurized and moves the lower tool part 3 up to the film to be separated.
  • the counter-pressure strip 6 of the lower tool part 3 strikes the foil and presses it with a force F1 against the knife 7a.
  • t2 represents the moment of penetration or penetration and thus the cutting through of the film.
  • the knife 7a is in contact with the counter-pressure strip 6 and the force F rises to a maximum value F2 which is generated by the pneumatic cylinder 4 and its compressed air supply and is also influenced by the upper end position of the pneumatic cylinder.
  • F2 a maximum value generated by the pneumatic cylinder 4 and its compressed air supply and is also influenced by the upper end position of the pneumatic cylinder.
  • the punching process is completed and the pressure of the pneumatic cylinder 4 is eliminated and thus also decreases the pressure force F to t4. From the time t4, the lower tool part 3 and the counter-pressure bar 6 away from the knife 7a and moves back to the normal position.
  • the force F1 required to separate the film is less than half the maximum force F2 with which the counterpressure strip 6 still acts on the knife 7a after the separation process.
  • the force curve according to the invention as a dash-dot line L is located. How this force curve is achieved will be explained in more detail with reference to the following figures.

  • the film lance 1 works in such a way that the film web 16 is not separated over the entire width, but is not severed at least in an edge region. This allows a controlled onward transport by the feed device.
  • the longitudinal cutting device 13 is formed in the illustrated embodiment as a knife assembly with a plurality of rotating circular blades, with which the film web 16 and the cover sheet 18 between adjacent troughs 21 and at the lateral edge of the film web 16 are severed, so that behind the longitudinal cutting device 13 individualized packages 20 are present.
