Definitions

  • the invention relates to a packaging machine according to the preamble of claim 1, and to a corresponding method for producing a vacuum packaging.
  • a generic packaging machine and a method for producing a vacuum packaging go out of the EP 1564147 A1 out.
  • a sealable vacuum bag is placed in the packaging machine such that a main portion of the package receiving the packaged product is in the first chamber while the opening of the bag is in a smaller, second chamber.
  • the advantage of this packaging machine is that in the two chambers, a different negative pressure can be generated so that from the outside a higher pressure on the packaging loads than inside. This higher external pressure stabilizes delicate products in the package, such as cheese or other porous products, which tend to be too low pressure to spew or burst the porous structures and thus damage the product.
  • a disadvantage of the conventional packaging machine is that its operation is relatively expensive.
  • a seal chamber is divided by the package into a sub-chamber and an upper chamber.
  • a quick, sudden venting of the chamber provides a pressure difference between the interior and the exterior of the package, after initially creating a predetermined vacuum.
  • the object of the present invention is to improve a packaging machine and a packaging method for producing a vacuum packaging with a view to more stable operation and higher-quality packaging results.
  • a first variant of the invention provides that the supply air valve is a control valve which depends on the difference in the measured by the two pressure measuring means pressure in the first and the second chamber and / or in dependence on the difference between the prevailing in a chamber Pressure and a predetermined final pressure for this chamber is adjustable.
  • control valve means in the context of the invention that the valve can not only assume a fully open and a fully closed state, but also a plurality of intermediate positions in which the control valve is partially open. These intermediate steps may be distributed in discrete opening steps or continuously between the fully opened and the fully closed positions. It would also be conceivable that the control valve is infinitely adjustable only in a certain range. It thus differs markedly from the above cited prior art, in which switching valves were used, which could be adjusted only between a fully open and a fully closed state.
  • Another advantage of the invention arises from the fact that the difference between the pressure measured by means of the two pressure measuring devices in the two chambers is determined and used as input for the regulation of the supply air valve.
  • the per unit of time in the first chamber supplied amount of air thus depends on this pressure difference.
  • the pressure difference is small, more air per unit time is supplied to the first chamber.
  • the pressure difference is larger, no or at least less air per unit time is supplied to the first chamber so as not to make the pressure difference between the two chambers too large. In this way, it is ensured that on the outside of the packaging in the first chamber, there is always an ideal pressure, so that damage to the products by bursting or beading of porous structures is reliably avoided.
  • By maintaining an optimum pressure difference constantly moreover, the processing time when producing a vacuum packaging can be shortened.
  • the supply air valve is a proportional valve whose degree of opening is inversely proportional to the difference of the pressure in the two chambers.
  • a proportional valve allows a continuous adjustment of its degree of opening between the fully closed and the fully open position.
  • the supply air valve can have either a linear or a non-linear control curve.
  • a non-linear control curve which has a non-linear profile relative to the pressure difference between the two chambers, is particularly advantageous.
  • This control curve could, for example, be S-shaped in order to allow as gentle a pressure regulation as possible.
  • a desired final pressure for one or both chambers and / or a desired pressure difference between the pressures prevailing in the two chambers is set on the packaging machine.
  • the supply air valve can then be controlled via a suitable control so that this target pressure difference is maintained as constant as possible. It is even better if the desired pressure difference is adjustable, for example via suitable control elements on the packaging machine.
  • the target pressure difference can be adapted to different products or to different materials of the packaging in order to always produce optimum packaging results.
  • the desired pressure difference need not be a single, concrete value, but the desired pressure difference may preferably be a pressure range. For example, if the desired pressure difference between the two chambers is 100 mbar, the target pressure difference may be a pressure range between 90 mbar and 110 mbar.
  • the degree of opening of the supply air valve is inversely proportional to the amount by which the actual pressure difference between the pressures prevailing in the two chambers deviates from the desired pressure difference.
  • the supply air valve has a first opening degree.
  • the supply air valve continues to open in proportion to the amount by which the actual pressure difference exceeds the target pressure difference. In this way, the fastest possible return of the actual pressure difference to the range of the desired pressure difference is made possible.
  • a dividing wall is provided between the two evacuable chambers. This partition has the advantage that different pressures can prevail in the two chambers.
  • an opening of the supply air valve is arranged to the first chamber in one of the partition wall exactly opposite wall of the first chamber.
  • This arrangement ensures that the supplied air initially acts on the end of the packaging remote from the dividing wall before the air sweeps along the packaging and flows to the dividing wall.
  • This has the advantage that residual air still contained in the packaging is pressed to open the packaging, so that the evacuation of the packaging is facilitated and accelerated.
  • the partition there may be a gap through which the first chamber and the second chamber are in fluid communication with each other.
  • a part of the packaging may be inserted into this gap in order to store and stabilize the packaging relative to the packaging machine.
  • the gap also allows a small exchange of air between the two chambers. This has the advantage that an air flow can be generated along the packaging, which is directed along the packaging to the opening. This facilitates the evacuation of the packaging.
  • the fluid connection between the two chambers allows a variant in which not each chamber is evacuated separately, but in which only in a chamber-preferably in the opening of the packaging receiving, the second chamber - an evacuation is provided. When evacuating the second chamber, the first chamber is automatically evacuated by means of the gap.
  • the opening of the supply air valve to the first chamber is preferably arranged in the height of this gap. This further promotes the formation of an air flow along the package, which is directed from the end of the package to the packaging opening and presses the residual air still contained in the packaging to open the package.
  • an adjuster for changing and adjusting the cross-sectional area of the gap is provided. This makes it possible to adjust the volume flow between the two chambers, d. H. the amount of air exchanged per unit time between the two chambers.
  • such an adjuster for changing and adjusting the cross-sectional area of the gap in the partition wall between the two chambers and independently of the pressure measurement in the two chambers and the formation of a Supply air valves are provided as a control valve.
  • the adjuster allows adjustment of the volume flow exchanged between the two chambers. Depending on the nature of the products to be packaged and the materials used for the packaging of this volume flow can now be changed to achieve the fastest possible or the highest possible evacuation of the packaging.
  • the adjuster can also be manually operated or adjustable.
  • the operation of the packaging machine is more comfortable when the adjuster is driven by a motor and the operator for this purpose, for example, by means of a control panel or control element gives appropriate setting commands.
  • the set values can be stored in a control of the machine.
  • the adjuster may have an adjusting screw which projects into the gap or which moves a blocking element projecting into the gap.
  • the partition between the two chambers or at least a part of this partition is mounted such that the cross-sectional area of the gap does not change, even if one or both chambers are evacuated.
  • the partition or at least a part thereof is resiliently mounted relative to the bottom, the lid or a wall of the chambers. This prevents, for example, a deflection of a lid of the packaging machine at a greatly reduced internal pressure to a displacement of the partition and thus leads to a change in the gap cross-sectional area, which could either prevent a pressure adjustment between the chambers or could lead to an immediate pressure equalization, both equally disadvantageous would be.
  • noses or projections could also be provided on the gap, which strike against the opposite gap side and thus prevent the gap from closing below a certain minimum opening area.
  • a significant improvement of the packaging machine can also be achieved by providing a bypass between the two chambers to be evacuated, in which a controllable bypass valve is arranged.
  • a controllable bypass valve By the degree of opening of the bypass valve can be controlled how much air flows from one of the chambers into the other chamber, so as to set the differential pressure between the two chambers also independent or at least largely independent of the gap.
  • the adjustable bypass valve It also makes it possible to adjust the pressure equalization between the two chambers to different numbers of bags or to different thick-walled bag without necessarily the gap would have to be changed. Alternatively, it would also be conceivable that no bypass between the two chambers is provided, but that is evacuated in the smaller chamber with full power and evacuated in the larger chamber with reduced power.
  • the invention further relates to a method for producing a vacuum packaging, wherein in a first and in a second evacuated chamber, the pressure is measured, from which the actual pressure difference determined and a controllable supply air valve depending on this actual pressure difference between in the controlling both chambers prevailing pressures, or in dependence on the difference between the pressure prevailing in a chamber and a predetermined final pressure for this chamber.
  • the supply air valve is opened in proportion to a pressure difference and / or if a desired pressure difference is predetermined by an operator.
  • the supply air valve can then be opened proportionally (or inversely proportional) to the extent to which the pressure difference between the pressures prevailing in the two chambers deviates from the desired pressure difference.
  • the desired pressure difference does not have to be a single, concrete value, but is preferably a finite pressure range.
  • a bypass with a bypass valve between the two chambers is provided for carrying out the method according to the invention.
  • the final pressure reached in the two chambers and the end vacuum reached there is determined by the position of the supply air valve and thus adjusted to a predetermined final vacuum, while the position of the controllable bypass valve prevailing between the two chambers differential pressure and, for example, to a predetermined differential pressure is equalized.
  • FIG. 1 shows a schematic representation of an embodiment of a packaging machine according to the invention 1. It serves to make a package 2 to a product 3 by suitable evacuation and sealing to a vacuum packaging.

  • In the supply air valve 13 is a control valve, which can preferably be adjusted continuously between a fully closed and a fully open position.
  • a controller 15 of the packaging machine 1 is connected via control and data lines 16 to the valves 9, 10, 13 and the pressure measuring devices 11, 12.
  • the measured values of the pressure in the two chambers 4, 5 determined by means of the pressure measuring devices 11, 12 are transmitted to the controller 15 via the data lines 16.

  • An adjuster or actuator 17 is provided to change the cross-sectional area of the gap 7 and adjust.
  • the adjuster 17 is designed as a set screw, which is guided in the partition wall 6.
  • An electric motor 18 outside the two chambers 4, 5 has a drive nut 19, which surrounds the adjusting screw 17. When the nut 19 is driven by the motor 18, it raises or lowers the adjusting screw 17 so as to change the free cross-sectional area of the gap 7. Also, the motor 18 is connected via a suitable control line to the controller 15.
  • the supply air opening 14, via which the supply air valve 13 supply air can be guided into the first chamber 4, is arranged in the partition wall 6 opposite wall 20 of the first chamber 4. In particular, it lies there at approximately the same height H with respect to the bottom 21 of the chamber 4 as the gap 7 in the partition wall 6.

  • the sealing tool is arranged in the second chamber 5 and it is also controlled by the controller 15.
  • the sealing tool 22, 23 could also be arranged in the first chamber 4.

  • an operator of the packaging machine can enter commands or set specific values, in particular a desired pressure difference for the pressure difference in the two chambers 4, 5 as well as the desired final pressure in one or both chambers.
  • This desired pressure difference can either be a single, concrete value or else a pressure range lying between two values. In the latter case, the range can be set either by the operator setting the lower and upper limits of this target pressure difference range. Alternatively, the operator may set a certain value within the target pressure difference range, for example, a middle range.
  • the packaging machine 1 itself or the operator set a tolerance range to this central value, for example, a percentage deviation of 5 or 10% up and down. If the actual pressure difference lies within this tolerance range around the predetermined pressure difference value, it is treated as lying within the desired pressure difference range.
  • the operation of the packaging machine 1 according to the invention or the process according to the invention proceeds as follows.
  • the operator inputs a desired pressure difference value or a desired pressure difference range as well as the desired final pressure in one or both chambers into the controller 15 into the packaging machine 1, for example 100 mbar, 150 mbar, 200 mbar or 250 mbar.

  • the operator opens the two chambers 4, 5 of the packaging machine 1 and places a packaging 2 filled with a product 3 into the packaging machine 1. This insertion can be done manually or automatically. After insertion, the product receiving portion 2a of the package 2 is located in the first chamber 4, while the opening portion 2b of the package 2 is located in the second chamber 5. The chambers 4, 5 are closed.
  • the controller 15 provides for opening the two evacuation valves 9, 10.
  • the pressure in the two chambers 4, 5 drops. Since the volume of the second chamber 5 is smaller than that of the first chamber 4, the pressure in the second chamber 5 decreases faster than in the first chamber 4. Since the opening 2c of the package 2 is in communication with the second chamber 5, the lower pressure of the second chamber 5 also in the interior of the package 2. As a result, the product receiving portion 2a of the package 2 is used to the product 3.
  • the pressure measuring devices 11, 12 monitor the pressure in the respective chambers 4, 5 continuously or at discrete intervals.
  • the corresponding pressure measured values are transmitted to the central controller 15, which calculates the pressure difference between the two chambers 4, 5.
  • This pressure difference increases until it reaches the tolerance range of the desired pressure difference. So that the pressure difference reaches this predetermined value faster, either the first evacuation valve 9 is opened after the second evacuation valve 10 or the supply air valve 13 is opened during the evacuation of the two chambers 4, 5.
  • the higher external pressure in the first chamber 4 presses the product-receiving portion 2a of the package 2 to the product 3.
  • Favored by the position of the supply air opening 14 in the wall 20 of the first chamber 4 forms a Air flow from this supply air opening 14 to the gap 7, preferably a laminar air flow. It sweeps along the product receiving portion 2a of the package 2, thus pushing the residual air contained in the package 2 toward the opening 2c of the package 2.
  • the supply air valve 13 designed as a control valve is slowly closed. This closing of the supply air valve 13 may be proportional to the speed at which the pressure difference approaches the target pressure difference. While the pressure difference is in the tolerance range of the desired pressure difference, the supply air valve 13 assumes a partially open state. This state is selected so that, with the evacuation valves 9, 10 still open, the pressure reduction in the two chambers 4, 5 takes place with the same rate as possible, so that the pressure difference between the two chambers 4, 5 remains within the predetermined tolerance range of the desired pressure difference. If, however, the pressure difference is still greater, the supply air valve 13 is further closed according to the degree of deviation from the desired pressure difference.
  • the controller 15 controls the valves 9, 10, 13 so that the target pressure difference between the two chambers 4, 5 is maintained as fast as possible and as long as possible during evacuation.
  • the sealing tool parts 22, 23 close around the opening portion 2b of the package 2 package to seal this opening portion 2b.
  • the vacuum package 2 is made. After opening the two chambers 4, 5, it can be removed from the packaging machine 1.
  • FIG. 2 shows a schematic representation of a second embodiment of the packaging machine according to the invention 1. This is largely identical to the in FIG. 1 illustrated first embodiment. In contrast to the first embodiment, however, the packaging machine 1 according to FIG. 2 In addition, a bypass 25 between the two chambers 4, 5, ie one the two chambers 4, 5 connecting Air line. In this bypass 25 is a controllable bypass valve 26. By means of the adjustable opening area of the bypass valve 26 can be regulated at what rate air flows through the bypass 25 when in the two chambers 4, 5, there is a pressure difference. In this way, the rate of pressure equalization between the two chambers 4, 5 can be controlled simultaneously. For suitable activation of the bypass valve 26, this is likewise connected via a control and data line 16 to the central controller 15. By providing the bypass 25 and the bypass valve 26, there is the advantage that the pressure adjustment between the two chambers 4, 5 can be independent of the gap 7 in the partition 6. This makes it possible to control the desired differential pressure between the two chambers 4, 5.
  • FIG. 3 shows in a time-pressure diagram, the course of the pressure in the two chambers 4, 5 in a cycle of the method according to the invention.
  • two proportional valves are provided, namely the supply air valve 13 and the bypass valve 26 in which the two chambers 4, 5 connecting bypass.
  • p4 represents the course of the pressure in the large chamber 4
  • p5 the course of the pressure in the small chamber 5
  • p22 the pressure exerted by the sealing tools 22, 23 pressure.
  • the curve S13 represents no pressure, but the position of the supply air valve 13, wherein the supply air valve 13 is the more closed, the higher the curve S13 in the diagram of FIG. 3 runs.
  • the pressure p5 in the smaller chamber 5 reaches the predetermined final pressure of here 100 mbar. From this point on, the supply air valve will be activated 13 at a constant opening width or at constant Zu Kunststoffrate and a differential pressure Ap2 between the two chambers 4, 5 is maintained. Between times t6 (at about 54 seconds) and t7 (at about 56 seconds), the packaging 2 is sealed by applying a pressure p22 by means of the sealing tools 22, 23 to which a sealing pressure is applied by means of a sealing membrane (not shown). Subsequently, a venting and opening of the chambers 4, 5 instead, until they have reached normal pressure again at the time t8 and the sealed package 2 can be removed from the packaging machine 1. This completes a complete work cycle.
  • FIG. 4 shows in a further time-pressure diagram, how the pressures p4, p5 in the two chambers 4, 5 behave when the bypass valve 26 is gradually opened during the evacuation of the two chambers 4, 5.
  • This opening of the bypass valve 26 causes the differential pressure ⁇ p between the two pressures p4, p5 to gradually decrease. From the comparison of Figures 3 and 4 shows that the position of the supply air valve 13 determines the final pressure reached in the two chambers 4, 5 or the final vacuum, while the position of the bypass valve 26 determines the prevailing between the two chambers 4, 5 differential pressure Ap.
  • FIG. 5 shows in a time-pressure diagram, a problematic situation that may occur without appropriate precautions in certain exceptional situations in the operation of the packaging machine 1 according to the invention. Shown again are the course of the pressures p4, p5 in the two chambers 4, 5, which are initially similar to those in FIG FIG. 3 kick off. At a time t9, however, the lid of the chambers 4, 5 starts to deform due to the pressure building up through the sealing membrane. This deformation causes the suspended on the lid parts of the partition wall 6, so that at one time increases the opening surface of the gap 7.
  • the gap forming part of the partition 6 can be suspended resiliently. In this way, a deflection of the lid of the packaging machine 1 during the build-up of the sealing pressure can be compensated by the membrane, so that the cross-sectional area of the gap 7 does not change, even if the Cover deformed.
  • the result is in FIG. 6 to see: under the same conditions as in FIG. 5 This time the differential pressure ⁇ p between the two pressures p4, p5 in the two chambers 4, 5 does not collapse.
  • the gap 7 can be kept constant, for example, at a gap height of 0.5 mm.
