Definitions

  • the present invention relates to a packaging system and method for producing pouches comprising a water-soluble film and a gel comprising a substrate treatment agent.
  • Known packaging systems dispense gel from one or more nozzles into a compartment formed in a water soluble film. After the correct amount of gel has been dispensed in the compartment, the flow of gel is stopped and the compartment and the nozzles are moved with respect to each other, such that the nozzles may dispense gel into a different compartment.
  • the gel being dispensed into the compartments is typically a viscous fluid with a tendency to degrade over time, resulting in an increase in viscosity or even solidification. This causes clogging of the nozzles when the system is temporarily out of use, for example during a scheduled or unscheduled machine stop. Separate operations are required, usually by manual labour, in order to unclog the nozzles and restart the packaging system. This leads to a loss of time and an increase in costs.
  • the invention provides a packaging system for producing pouches comprising a water-soluble film and a gel comprising a substrate treatment agent, the packaging system comprising:
  • the pins are in the inactive position.
  • the pin holder is moved into the active position. Gel present in the nozzle through hole is then pushed out of the nozzle by the pins. This prevents the gel from solidifying in the nozzle through holes while the machine is not operating.
  • the pin holder is moved back to the inactive position. The space inside the nozzle through holes that was occupied by the pins while the pin holder was in the active position is thereby opened, such that gel can flow from the reservoir through the nozzle through hole out of the nozzles.
  • This packaging system thereby prevents clogging of the nozzles during a machine stop, obviating the need for separate unclogging operations. This allows faster restarts after scheduled and unscheduled machine stops.
  • the nozzle number is larger than one.
  • the pins of each dispenser are held by a single shared pin holder.
  • the pins in the active position of the pin holder, the pins extend along the complete through hole of their respective associated nozzles, the pins optionally ending flush with the nozzle openings of their respective associated nozzles.
  • the pins in the active position of the pin holder, extend in a direction from the reservoir to their respective associated nozzle openings along the complete through hole of their respective associated nozzles, the pins optionally ending flush with the nozzle openings of their respective associated nozzles.
  • each nozzle opening is configured to dispense the gel out of the respective gel dispenser.
  • each nozzle opening is located at a nozzle through hole end of the respective nozzle through hole.
  • the through holes of the nozzles and their respective associated pins have a same shape such as a cylindrical, conical, or pyramid shape.
  • the packaging system comprises an upstream heating device for heating the gel between the nozzle and the gel supply to an upstream gel temperature.
  • the packaging system comprises a nozzle heating device for heating the gel at the nozzle to a nozzle gel temperature.
  • the nozzle gel temperature is higher than the upstream gel temperature.
  • the upstream gel temperature and the nozzle gel temperature are typically in a range of 128 to 140 degrees Celsius, dependent on the type of gel used.
  • a nozzle diameter of the nozzle openings is between, and including, 1,4 and 2,2 mm, preferably between, and including 1,6 mm and 2,0 mm, more preferably 1,8 mm.
  • the gel channel is at least partially straight and at least partially concentric with the pin holder.
  • the gel channel may extend at least partially through the pin holder.
  • the gel channel is offset with respect to each of the nozzle openings.
  • the pins and the nozzle through holes extend parallel to each other.
  • the gel has a viscosity of between 1000 Cp and 3000 Cp.
  • One Cp equals one millipascal-second or mPa*s.
  • the filling device comprises one or more fume extraction openings in fluid communication with one or more fume extraction channels for extracting fumes originating from the gel dispensed by the gel dispenser, wherein optionally the one or more fume extraction channels are heated to a temperature above a condensation temperature of the fumes.
  • the one or more fume extraction channels are in fluid communication with a flow generating device, such as a motorised fan or low pressure source, and the flow generating device is arranged downstream from the one or more fume extraction openings with respect to a flow through the one or more fume extraction channels.
  • a flow generating device such as a motorised fan or low pressure source
  • the multiple gel dispensers comprising a dispenser number of gel dispensers, wherein:
  • the dispenser number can be any integer.
  • the dispenser spacing preferably is an odd integer multiplied by the mould spacing if the dispenser number is even. If the dispenser number is odd, the dispenser spacing preferably is an even integer multiplied by the mould spacing.
  • the dispenser spacing between adjacent dispensers is preferably constant. This allows filling of all moulds while preventing double filling of some moulds.
  • the dispenser spacing is defined along the conveying direction and the mould spacing is defined along the conveying direction.
  • Adjacent dispensers are dispensers between which no other dispenser is arranged when seen along the direction along which the dispenser spacing is defined.
  • Adjacent moulds are moulds between which no other moulds are arranged when seen along the direction along which the mould spacing is defined.
  • the packaging system comprises multiple first gel dispensers arranged along a first dispenser row and multiple second gel dispensers arranged along a second dispenser row, wherein the first dispenser row extends in a horizontal direction perpendicular to the conveying direction and the second dispenser row extends in the horizontal direction perpendicular to the conveying direction.
  • the packaging system comprises a walking device for moving the filling device along the mould trajectory in the conveying direction from a start position into an end position and vice versa, wherein the walking device is configured to move the filling device from the start position to the end position in a synchronised manner with the mould conveyer.
  • the step size of the walking device equals the dispenser number multiplied by the mould spacing.
  • the step size is preferably constant, although a varying step size would also be possible. This allows filling of all moulds while preventing double filling of some moulds.
  • the walking device and the mould conveyer move at the same speed along the mould trajectory while the walking device moves from the start position to the end position.
  • the gel dispensers line up with the moulds while the walking device moves from the start position to the end position.
  • the mould conveyer preferably moves in a continuous manner with a constant speed.
  • the subsequent first associated mould is the second intermediate mould referred to earlier, while the second associated mould is the first further mould.
  • the packaging system comprises a further film supplying device configured to position a water-soluble further film on the film and over the gel in the compartments in order to form a web of pouches holding the gel between the film and the further film wherein the packaging system optionally comprises a connecting device to connect the film and the further film to each other.
  • the invention also provides a method of producing pouches using a packaging system according to any of the above embodiments according to the invention, the method comprising the steps of:
  • the pins are in the inactive position.
  • the pin holder is moved into the active position. Gel present in the nozzle through hole is then pushed out of the nozzle by the pins. This prevents the gel from solidifying in the nozzle through holes.
  • the pin holder is moved back to the inactive position. The space inside the nozzle through holes that was occupied by the pins while the pin holder was in the active position is thereby opened, such that gel can flow from the reservoir through the nozzle through hole out o the nozzles.
  • This method thereby prevents clogging of the nozzles during a machine stop, obviating the need for separate unclogging operations. This allows faster restarts after scheduled and unscheduled machine stops.

  • the method comprises the steps of:
  • the method comprises the step of removing fumes originating from the gel dispensed into the first intermediate compartment and the second intermediate compartment via the fume extraction openings.
  • FIG. 1 shows an overview of a first example of the packaging system 1 according to the invention.
  • the packaging system 1 is configured produce pouches 2 comprising a water-soluble film 3 and a gel 4.
  • the gel 4 comprises a substrate treatment agent, for example a detergent, rinsing aid, water hardness regulator or color protection agent.
  • the packaging system 1 comprises multiple moulds 5. Each mould 5 has a mould cavity 6 for forming a compartment 7 in the film 3.
  • a mould conveyor 8 moves the moulds 5 in a conveying direction 9 along a mould trajectory, more specifically an endless mould trajectory.
  • the mould conveyor 8 is configured as a mould conveyor belt 70.
  • the moulds 5 are moved along a film supplying device 11 configured to position the film 3 on the moulds 5. Subsequently, a compartment forming device 12 positions parts of the film 3 in the mould cavities 6 to form the compartments 7 in the film 3. After that, a filling device 13 having multiple gel dispensers 15 fills the compartments 7 with the gel 4. Each gel dispenser 15 dispenses gel 4 into an associated compartment 7 of the film 3 positioned in an associated mould 5.
  • a further film supplying device 65 positions a water-soluble further film 66 on the film 3 and over the gel 4 in the compartments 7 in order to form a web 67 of pouches 2 holding the gel between the film 3 and the further film 66.
  • the web 67 of pouches 2 can be cut to form individualised pouches 2.
  • the packaging system 1 also comprises a connecting device 68 to connect the film 4 and the further film 66 to each other.
  • the mould conveyor 8 is configured to continuously move the moulds 5 in the conveying direction 9 during the filling of the compartments 7.
  • the packaging system 1 comprises a walking device 43 configured to move the filling device 13 over a walking distance 61 from a start position 44 into an end position 45, and vice versa.
  • the walking device 43 is configured to move the filling device 13 along the mould trajectory in the conveying direction 9 from the start position 44 to the end position 45 during the filling of the compartments 7 and from the end position 45 to the start position 44 after the filling of the compartments 7 has been completed in order to start a new filling cycle. This allows synchronous movement of the filling device 13 with the compartments 7 to be filled as the moulds 5 are continuously moved by the mould conveyor 8.
  • the gel dispensers 15 line up with the compartments 7 and the gel dispensers 15 move in substantially the same direction at substantially the same speed as the moulds 5.
  • the walking distance 61 along the mould trajectory between the start position 44 and the end position 45 is less than or equal to double a mould spacing 39 of adjacent moulds 5.
  • FIG 2 shows an overview of a second example of the packaging system 1 according to the invention.
  • the main difference with respect to the packaging system 1 of Figure 1 is that the mould conveyer 8 is configured as a rotary mould drum 71 instead of a mould conveyor belt 70.
  • FIG. 3 shows a cross section of the filling device 13 of the packaging system 1 of an embodiment according to the invention.
  • Each gel dispenser 15 comprises a reservoir 18 which is in fluid communication with the gel supply 14.
  • the gel supply 14 comprises multiple gel pumps 14A and multiple gel channels 19.
  • Each gel channel 19 connects one of the multiple gel pumps 14A to one of the multiple gel dispensers 15.
  • the gel pumps 14A pump the gel 4 via the gel channels 19 to the reservoirs 18. From the reservoir 19, the gel 4 is dispensed through nozzle openings 22 of nozzles 20 via nozzle through holes 21.
  • Each gel dispenser 15 comprises a pin holder 23 holding a pin number of pins 24.
  • the pin number is equal to the number of nozzles 20 (the nozzle number) of the gel dispenser 15, and each pin 24a-g is associated with one of the nozzles 20a-g (see Figure 6 ).
  • the pin number and the nozzle number are preferably larger than one.
  • the pins 24 are held by a single shared pin holder 23.
  • the pin holder is moveable by a pin actuator 25 into an active position 26 and an inactive position 27.
  • each pin 24 extends into the nozzle through hole 21 of its associated nozzle 22.
  • the pins 24 are arranged in the reservoir 18.
  • Figures 4 and 5 show a cross section of a section of the filling device of 13 Figure 3 , wherein the pin holder is in the inactive position 27 and the active position 26, respectively.
  • the nozzle openings 22 are in fluid communication with the reservoir 18, such that gel 4 may flow through the nozzles 20.
  • the pins 24 Upon moving the pin holder 23 from the inactive position 27 to the active position 26, the pins 24 enter the nozzle through holes 21, thereby expelling gel 4 from the nozzle through holes 21.
  • the pin holder 23 is in the inactive position 27.
  • the pin holder Upon stopping said operation, the pin holder is moved by the pin actuator 25 to the active position, such that gel 4 present in the nozzles 20 is expelled out of the nozzle openings 22. This prevents gel 4 from solidifying inside the nozzle through holes 21. Preventing gel solidification inside the nozzle through holes 21 prevents clogging of the nozzles 20.
  • the pin holder 23 is moved back to the inactive position 27, such that a free channel is created in the nozzle through holes 21 where the pins 24 were located when the pin holder 23 was in the active position 26.
  • the pins 24 and the nozzle through holes 21 extend parallel to each other.
  • the pins 24 In the active position 26 of the pin holder 23, the pins 24 extend along the complete through hole 21 of their respective associated nozzles 20. More specifically, in the active position 26 of the pin holder 23, the pins 24 extend in a direction from the reservoir 18 to their respective associated nozzle openings 22 along the complete through hole 21 of their respective associated nozzles 20.
  • the pins 24 end flush with the nozzle openings 22, as shown in Figure 5 .
  • the through holes 21 of the nozzles 20 and the pins 24 have a same shape such as a cylindrical, conical, or pyramid shape. This way, the pins 24 can effectively expel gel 4 from the nozzle through hole 21 upon insertion of the pins 24 into the nozzle through holes 21 by movement of the pin holder 23 from the inactive position 27 to the active position 26.
  • Each nozzle opening 22 is configured to dispense the gel 4 out of the respective gel dispenser 15.
  • Each nozzle opening 22 is located at a nozzle through hole end 80 of the respective nozzle through hole 21 (see Figure 4 ).
  • the gel 4 has a viscosity of between 1000 Cp and 3000 Cp.
  • the nozzle diameter 34 of the nozzle openings 22 is between, and including, 1,4 and 2,2 mm, preferably between, and including 1,6 mm and 2,0 mm, more preferably 1,8 mm. Other values may be chosen to optimise for other gel properties and/or other operating conditions of the packaging system 1.
  • the viscosity is determined by rheological measurements.
  • the rheological measurements were performed on samples of the gel by using an Anton Paar MCR301 rheometer (SN80108634) equipped with a set-up with a Peltier heated cylinder geometry (P-CTD200 SN81433896) in combination with a cylinder geometry (CC27, SN37581) and solvent trap to avoid evaporation of solvent. Measurements on the samples were performed in rotation as well as in oscillation.
  • the gel channel 19 is at least partially straight and at least partially concentric with the pin holder 23. As shown in Figures 3-5 , the gel channel 19 may extend at least partially through the pin holder 23. This tends to allow a compact construction.
  • the gel channel 19 is offset with respect to each of the nozzle openings 22 (see also Figure 7 ).
  • the packaging system 1 comprises an upstream heating device 32 for heating the gel 4 between the nozzles 20 and the gel supply 14 to an upstream gel temperature. Additionally or alternatively, the packaging system 1 may comprise a nozzle heating device 33 for heating the gel 4 at the nozzles 20 to a nozzle gel temperature. Preferably, the nozzle gel temperature is higher than the upstream gel temperature.
  • the gel supply 14 provides a pressure to dispense the gel 4 from the nozzles 20.
  • This pressure is relieved.
  • the stringing time is the time it takes until the gel 4 stops dripping from the nozzles 20 after the pressure has been relieved. It is beneficial to wait until the gel 4 has stopped dripping from the nozzles 20 before dispensing gel 4 into another compartment 7, as this reduced spillage of gel 4.
  • the integrity of the formed pouches 2 may be reduced if gel 4 is leaked onto a sealing area of the pouches 2. Reducing the stringing time thus allows faster operation, as less time is required to wait for the gel 4 to stop dripping from the nozzles 20.
  • Heating the gel decreases the viscosity of the gel, leading to less pressure required to dispense the gel 4 from the nozzles 20. Additionally, the stringing time of the gel 4 is reduced at higher temperatures. However, the gel 4 deteriorates faster at higher temperatures, such that it is desirable to prevent heating the gel 4 too much or for too long. Therefore, it is beneficial to increase the gel temperature just before it is dispensed, e.g. at the nozzles 20.

  • the nozzles 20 are arranged in a dispensing shape 30.
  • the nozzles 20 are configured to dispense the gel 4 into the associated compartment 7 in a deposit shape 31.
  • the deposit shape 31 and the dispensing shape 30 may be elongated. Arranging the nozzles 20 in the dispensing shape 30 allows dispensing the gel 4 in a particular shape, such that the gel 4 can be arranged in a particular shape in the finished pouch 2.
  • a recess 31A may be present in the mould 5 in order to further control the final shape of the gel 4 in the finished pouch 2.
  • Figure 8 schematically shows a top view of a mould 5.
  • two recesses 31A are present to form two 'swooshes' in the compartment 7.
  • the gel 4 is dispensed into the compartment 7 formed in the mould 5 in the deposit shape 31. More specifically, the gel 4 is dispensed onto the film 3 in one or both of the recesses 31A, such that the gel 4 follows the ⁇ swoosh' shape in the formed pouch 2.
  • the deposit shape 31 may be any other shape, preferably elongated. Different types of gel 4 may be dispensed in the film in the different recesses 31A. Any number of recesses 31A, including one, may be present in the mould 5.

  • the two dispenser rows 40, 41 each comprise three gel dispensers 15. This way, more compartments 7 may be supplied with gel 4 simultaneously. This tends to increase a throughput of the packaging system 1.

  • the dispenser spacing 38 is three times the mould spacing 39 of adjacent moulds 5, similar to what is shown in Figure 11 .
  • the dispenser number is 2.
  • the multiple gel dispensers 15 thus comprise a first gel dispenser 40A and a second gel dispenser 41A.

  • the first gel dispenser 40A and the second gel dispenser 41A are shown in a relative position with respect to the moulds 5. Because the walking device 43 moves the gel dispensers 15 synchronously with the moulds 5 during the filling operations, the relative position of the first gel dispenser 40A and the second gel dispenser 41A with respect to the moulds 5 does not change during dispensing of gel 4 into the compartments 7, but only when the dispensing of the gel 4 during that filling operation has been completed.

  • the first gel dispenser 40A is configured to, during the subsequent filling operation depicted in Figure 12C , dispense gel 4 into a second intermediate compartment 55 of the film 3 positioned in the second intermediate mould 54 during movement of the filling device 13 from the start position 44 to the end position 45.
  • the second gel dispenser is configured to, during the subsequent filling operation depicted in Figure 12C , dispense gel 4 into a first further compartment 56 of the film 3 positioned in a first further mould 57 during movement of the filling device 13 from the start position 44 to the end position 45.
  • the first further mould 57 is arranged upstream from the second associated 51 mould along the conveying direction 9 at two mould spacings 39 from the second associated mould 51.
  • the second gel dispenser 41A is configured to, during the preceding filling operation depicted in Figure 12B , dispense gel 4 into a first intermediate compartment 58 of the film 3 positioned in the first intermediate mould 53 during movement of the filling device 13 from the start position 44 to the end position 45.
  • the first gel dispenser is configured to, during the preceding filling operation depicted in Figure 12B , dispense gel 4 into a second further compartment 59 of the film 3 positioned in a second further mould 60 during movement of the filling device 13 from the start position 44 to the end position 45.
  • the second further mould 60 is arranged downstream from the first associated mould 49 along the conveying direction 9 at two mould spacings 39 from the first associated mould 49.
  • the fume extraction openings 35 are arranged over the first intermediate mould 53 and the second intermediate mould 54 (see also Figure 11 , which shows that the fume extraction openings 35 are arranged between the first gel dispenser 40A and the second gel dispenser 41A).
  • the fume extraction openings 35 are positioned to extract any fumes originating from the gel 4 in the first intermediate compartment 58 close to the first intermediate compartment 58. This tends to reduce the spread of such fumes through the packaging system 1 and its environment, leading to relatively low contamination by fumes and condensed fumes.
  • the first associated mould 49, the second intermediate mould 54, and the second further mould 60 are odd moulds 47.
  • the first intermediate mould 53, the second associated mould 51, and the first further mould 57 are even moulds 46.
  • the compartments 7 of odd moulds are supplied with gel by the first gel dispenser 40A, while the compartments 7 of even moulds are supplied with gel 4 b the second gel dispenser 41A.
  • the walking device 43 moves the gel dispensers 15 synchronously with the moulds 5 during the filling operations in repeated walking cycles.
  • Each walking cycle comprises moving the filling device 13 comprising the gel dispensers 15 along the mould trajectory from the start position 44 to the end position 45 and back again after the gel 4 has been dispensed into the moulds 5.
  • the mould conveyer 8 moves the moulds 5 along the mould trajectory over a step distance 61A.
  • the mould conveyer 8 moves the moulds 5 along the mould trajectory over the walking distance 61, since the walking device 43 moves the filling device 13 in a synchronised manner with the mould conveyer.
  • the mould conveyer 8 may alternatively move the moulds 5 over a slightly different distance from the walking distance 61, as long as the gel 4 can still be dispensed into the compartments 7 without spillage.
  • the step distance 61A is larger than the walking distance 61.
  • the step distance 61A is equal to the number of gel dispensers 15 in the filling device 13 when seen along the conveying direction 9, multiplied by the mould spacing 39.
  • the filling device 9 has two gel dispensers 40A, 41A when seen along the conveying direction 9, such that the step distance 61A is twice the mould spacing 39.
  • the first gel dispenser 40A Upon starting the walking cycle, the first gel dispenser 40A is arranged over the first associated mould 49 and the second gel dispenser 41A is arranged over the second associated mould 51. While the walking device 43 moves the filling device 13 from the start position 44 to the end position 45, the conveyer 8 synchronously moves the moulds 5 in the conveying direction 9. Simultaneously, the first gel dispenser 40A dispenses gel 4 into the first associated compartment 48 and the second gel dispenser 41A dispenses gel 4 into the second associated compartment 50. Dispensing of gel 4 from the first and second gel dispenser 40A, 41A stops when or before the filling device 13 reaches the end position 45. The walking device 43 moves the filling device 13 back to the start position 44 after the filling device 13 has reached the end position 45. A delay may be present, such that the filling device 13 pauses at the end position 45 or the start position 44 before starting a new walking cycle.
  • a new walking cycle is started.
  • the first gel dispenser 40A is then arranged over the subsequent first associated mould 63 and the second gel dispenser 41A is then arranged over the subsequent second associated mould 64 and a new walking cycle is started.
  • the subsequent first associated mould 63 is arranged at the step distance 61A along the conveying direction 9 from the first associated mould 49 and the subsequent second associated mould 64 is arranged at the step distance 61A along the conveying direction 9 from the second associated mould 51.
  • the subsequent first associated mould 63 is the second intermediate mould 54 and the subsequent second associated mould is the first further mould 57.
  • the packaging system 1 described above ensures that all compartments 7 of the film are filled, with the possible exception of some compartments 7 near the beginning or end of the web of pouches 67.
  • a different number of gel dispensers 15, a different step size, and/or a different dispenser spacing 38 may be used while still attaining this goal.
  • the dispenser spacing 38 is an odd integer multiple of the mould spacing 39 for an even number of gel dispensers 15 when seen along the conveying direction 9 and the dispenser spacing 38 is an even integer multiple of the mould spacing 39 for an odd number of gel dispensers 15 arranged along the conveying direction 9.
  • the step size equals the number of gel dispensers 15 when seen along the conveying direction 9 multiplied by the mould spacing 39.
