Definitions

  • the invention relates to a method for producing, filling and sealing of plastic bags with dusty or granular bulk material and for closing the filled bags.
  • Such a method is for example from the DE 93 01 355 U known.
  • a device for producing, filling and closing unilaterally open preferably provided with gusseted bags of thermoplastic described in which a first welding and separation station to form the bag with bottom seam, a filling station and a second welding station for closing the bag available.
  • these filling machines are classified in the FFS ( F orm F ill and S eal) category.
  • the filling of dusty goods according to the known filling method described usually leads to a significantly inflated product volume or to a significant reduction in bulk density, since the product accumulates heavily in the free fall with air. This, in turn, leads to bottling the product initially much more packaging material is needed. In addition, the air must be able to escape from the bag again, otherwise it can not be stacked or stored.
  • a film tube can be unwound from a settlement.
  • the invention makes use of the fact that less dust is formed when the mouth of the Be colllorgans is below the Be colllgutsaustrittsö réelle of the metering. It is surprising that meaningful signals can be obtained with load cells, while there is mechanical contact of the filling material in the bag and the metering device.
  • the filling member mainly generates higher-frequency interference signals, which can be eliminated by filtering the signals.
  • Another measure that can increase filling speed and quality of measurement is a relative movement of dosing and bag during the filling process. When this relative movement is uniform, spurious signals are limited. This is especially true when the sack is moved uniformly.
  • the measured values obtained during the submillar filling can advantageously be used as weight measured values for checking or regulating the bag weight during filling.
  • This definition implies that, based on the weight measurements, the time at which the bag filling ends is determined. It also includes that a control of the filling speed and / or the speed of the relative movement between the bag and Be Pavllorgan is made.
  • the filling speed that is, the weight increase per unit time or the first derivative of the weight after the time, can be used to detect errors that occur during the filling process.
  • Such flaws can include a sack crack, which usually results in a rapid decrease in weight gain.
  • the outlined procedure is believed to work best when the control unit emits a warning signal as the weight gain moves out of a desired range.
  • the warning signal can be used by the control unit and / or the machine personnel to correct the error.
  • monitoring the first derivative of weight gain over time provides insights into the quality of the filling process and early fault detection.
  • a measurement with a radiation sensor can also be used to determine the Be Glallgutstandes.
  • a radiation can be used which penetrates the bag material, but not the filling material.
  • On the side facing away from the radiation emitter side of the bag radiation can only be collected by a suitable sensor when the transmitter and receiver are located above the Gregutspiegels.
  • the speed with which the product level rises and the speed of the relative movement between the bag and the filling device should be matched to one another. At exactly the same speed, the distance between the mouth and Medgutapt remains constant, which may be desirable.
  • This warning signal which of course can also lead manually (by the machine operator) or automatically (by a control device) to a control process, can reveal or expose a whole series of errors or failure mechanisms.
  • This teaching also appears to be advantageous for non-dusty filling goods.
  • the second period may overlap with the first period in which the weight gain is controlled. It may be shorter, longer, or the same as or the first, and may be before, during, or after the first one.
  • volumetric weight determination means for example, that a measured or known number of screw revolutions is multiplied or otherwise mathematically linked to a known product delivery rate per revolution, so that the weight or volume of the material conveyed into the bag at one time is determined or included can be estimated with sufficient accuracy.
  • the load cells can again assume the provision of measured values.
  • load cells for the purposes of this document covers all suitable weight sensors such as scales and just the load cells themselves.
  • load cells those weight sensors that contain electrical resistances arranged in the form of a Wheatstone bridge.
  • the resistors change their ohmic resistance when deformed.
  • the resistors are mounted on an element that deforms as the weight changes. Accordingly, the electrical output values of the Wheatstone bridge, which underlie the weight measurement change.
  • empirical weight measurement is a measure or estimate that is only or largely due based on empirical values (eg, during a time T, a volume V of a particular filling material is filled).
  • Explicit use can also be made in a fourth period of time, which can again be configured in position and duration as desired at the other time periods. This fourth period of time is advantageous at the end of the filling process.
  • the filling can be carried out for the benefit of the overall process, while the outlet of the filling element is located above the filling material level.
  • This phase of filling for example, can also be found at the end of the filling process and used to enable a sensitive and accurate dosing of the filling material.
  • the filling is advantageously carried out with a method according to the invention, among other cement, titanium dioxide and all kinds of plastic dusts into consideration.
  • the expert should understand under dusty goods bulk goods that just can not be filled on an FFS machine, unless a special filling process that often uses screws to guide the bulk material, is used.
  • Devices for carrying out the method according to the invention are generally controlled and / or regulated by control devices which are loaded with stored command sequences which arrange and / or monitor the methods described above.
  • These control programs are stored either on components of the control device or on other data carriers such as CDs or DVDs. It is also possible to send parts or the entirety of such programs.
  • data set is used in the context of this application. This term also includes the sending of the relevant electronic information via networks, for example by e-mail.
  • the closed at the lower end empty bag 11 is a horizontally displaceable transport, such as a gripper 18, passed and transported to the filling station.
  • the filling station takes over a further transport 4, which consists of 3,4,5, the bag section.
  • the empty bag is now opened with a suction system 16.
  • the gripper 4 or be moved in the Z direction (sackeinafter).
  • the connecting piece of the transport system 3 is moved into the bag and protects the sack inner surfaces from contamination by possible product adherence to the metering tube 2,21.
  • the opened bag is pulled by the transport system 3,4,5 on the metering tube 2,21 until the lower end of the bag is approximately equal to the Gregutaustrittsö réelle 31.
  • the bag bottom support device 32,33,34 is driven in the embodiment shown below the sack floor.
  • a bag bottom support device 32, 33, 34 is not absolutely necessary. Rather, the relative movement of the bag relative to the Be Stirllorgan 2,21 mainly caused by the fact that the frame 5 along the guide 6 moves. This is represented by the double arrow 35. In this embodiment of the invention, therefore, the bag is moved relative to the Be refhapllorgan 2,21.
  • the closure tube 21 is lifted and releases the product outlet opening 31.
  • the product / bulk material 24 is filled in the bag. Meanwhile, the transport system 3,4,5 lowers the bag in such a way that the product outlet opening 31 is always below the filling level. However, even before the end of the metering of the product / bulk material 24, the product outlet opening 31 may be located at least once above the filling level 38.
  • the closure tube 21 is lowered and closes the product outlet opening 31 by making contact with the closure 20.
  • the connecting piece is pulled out of the bag.
  • the gripper (s) 4 of the transport system 3, 4, 5 is or will now be moved counter to the Z direction (out of the bag) and tightens the opening area at the upper edge 25 of the previously opened bag.
  • vibration generators / beaters 29 This effect of product compaction can be enhanced by the additional use of vibration generators / beaters 29. It is advantageous here to set the dosing tube 2, 21 in vibration by means of a vibration generator 29, since it is located within the product at least with parts of its lateral surface during filling. The vibrations are transmitted from the dosing 2.21 to the filling material 24, in which then takes place a compression. Another advantage of the "vibrating metering tube" 2.21 is that the formation of product adherence to the metering 2.21 is thereby largely avoided.
  • the vibrator 29 could also be arranged on the "Sackêtunterstützungsvortechnisch" 34!
  • a particularly advantageous embodiment of the carriage is the frame 5 together with the neck 3, transport 4 and the absorption 16 to sensors to store.
  • the sensors send their signal to a weighing electronics, which ultimately controls the dosing process.
  • the metering or pipe 2 In the metering or pipe 2 is a screw 7, can be promoted with the filling material 24 from the hopper 1 without much dust in the bag 8.
  • the various sensors 26 (in particular weighing sensors or load cells) indicate advantageous locations for attaching such sensors.
  • the conveyor belt 27 transports the filled bags (8). In the vicinity thereof, the checkweigher 30 and the vibration generator 29 are mounted.
  • FIGS. 3 to 5 show the time course of the bag weight in three embodiments of the invention. With respect to these figures, the terms previously used with respect to monitoring the filling rate g / t are used.
  • FIGS. 7 to 9 show the same embodiments and use the terms already used above with respect to the UnterLitebe colllung with simultaneous generation of measurement signals. This distinction increases the clarity and facilitates the distinction between inventive and non-inventive filling method.
  • FIG. 3 the time course of the weight increase of a bag in the execution of a bag filling process is shown.
  • the bag weight g is plotted on the vertical axis and the time t on the horizontal axis.
  • Interference signals are caused here mainly by the Be Schollorgan 2,21 whose Basal Bachsö réelle 31 is yes in the period Z 3 , which coincides here with the phase 1 and time Z 2 , below the Be Schollgutapts 38 is located.
  • the filling element will be at the beginning of the filling above the filling material level 38, since there is still no or too little filling material in the bag 8. This circumstance is taken into account here by the fact that the time period Z 3 does not begin at time 0 but at time T 2 .
  • the phase P 2 of the bag filling begins.
  • this point in time will be regarded as having been attained if, on the basis of the volumetric measurement or estimation of the bag weight, it can be assumed that a certain proportion G 1 of the bag target weight G target has been reached. This percentage can be 95%.
  • some parameters of the bag filling change The bag weight is actually monitored by the evaluation of the load cell signals and the filling takes place while the Be Glallorgan 2,21 is located entirely above the Gregutapt 38. This improves the quality of the weight measurements.
  • the monitoring of the weight increase is carried out during the entire filling process in this embodiment.
  • the filling process ends when the target weight G target is reached.
  • the termination is performed automatically by the control device, not shown, when the load cells 26 report the desired signals to the control device.
  • the filling rate is lower in Phase 2 than in Phase 1.
  • FIG. 4 Another variant of this procedure is in FIG. 4 illustrated. It is sufficient at this point, the differences to the in FIG. 3 To be mentioned embodiment:
  • the period Z 4 in which the signals of the load cells are also used to control / regulate the bag weight, lasts during the entire filling process. There is no volumetric weight control. It is advantageous if the interference signals, which arise in particular during the submillar filling (Z 3 ), are eliminated by filters on the measuring signals.
  • FIG. 5 is dispensed with different phases of the filling process.
  • the weight of the bag is used for weight control (period Z 4 ).
  • the Submirror method filled (period Z 3 ).
  • a reduction of the bag speed does not occur.
  • FIG. 6 shows how the in FIG. 5 illustrated embodiment, the first derivative of the weight after the time g / t during the filling operation behaves. It is constant.
  • the curly bracket S indicates the desired range. This does not necessarily have to be symmetrical about the setpoint G / T nominal .
  • the target range S has a lower S U and an upper S O limit.
  • the arrows 36, 37 indicate that the value g / t can leave the target range if an error occurs.
  • a course of the weight change according to the arrow 36 can occur as a result of a blind crack.
  • an alarm is triggered, which can trigger measures of the machine personnel and / or the control device.
  • FIG. 7 shows again the same embodiment as FIG. 3 but additionally uses the terms introduced in relation to the measurement of the bag weight during the filling of the lower mirror.
  • the phase P U in which the submirror process is filled is equivalent to the third time period Z 3 .
  • This period is preceded here by the phase P L , in which the mouth 31 of the Be Glallorgans 2 is not below the level of contents 38, since the mouth 31 is a minimum distance AM above the bottom of the bag 39 and there is not enough good in the bag 8 to to cover the mouth 31.
  • the relative velocity v R between the sack 8 and the metering device 2 is set so that it is slower than the speed v F , with which the filling material rises in the bag.
  • v R can also be zero here.
  • the filling material level 38 "overtakes" the mouth 31 until a desired distance A setpoint between the level of contents 38 and the mouth 31 is reached. From this point in time T 2 , the speeds v R and v F are adjusted, so that the distance A target is maintained.
  • the phase P M in which the measured values are utilized in any desired form while being filled in the submirror process, thus lasts between the times T 2 and T 1 during the entire submirror filling.
  • the overlap between the periods P R and P L indicates that there is still a relative velocity greater than zero in the phase P L (slowed relative movement v R between the sack 8 and the metering element 2).
