Description

Technical Field

[0001] The present disclosure generally relates to filling devices, and more specifically, preferably to a filling device assembly configured to fill a pourable assembly with a flowable substance. It is desirable that the filling of the pourable assembly be performed in a sterile environment within the filling device assembly. Multiple pouch filling methods, as well as mechanisms and methods for moving the pourable assembly within the filling device assembly, and the configuration of the nozzle assembly, are disclosed.

Background Art

[0002] Flexible packaging containers and the filling thereof are known in the art. Such flexible packaging containers generally include flexible bags or pouches filled through a rigid spout. The use of pouches filled with flowable substances is becoming increasingly widespread.

[0003] Such pouches are generally filled with a flowable substance in a filling device assembly. It is increasingly desirable to fill in a sterile environment and to minimize the use of preservatives and chemicals in the flowable substance. Such filling can be either hot filling or cold filling. There is always a need to improve the filling process and equipment for filling packaging containers and aseptic packaging, among various packaging containers, especially with a pourable assembly.

[0004] In particular, such filling devices often include multiple sterilization steps. It is desirable to improve the removal of fluids (liquids, vapors, and / or gases) used in multiple sterilization steps so as to minimize the contamination of the flowable substance filled into the pourable assembly. In addition, it is desirable to maximize each action within the pourable assembly by improving the circulation of multiple different fluids associated with the preparation of the pourable assembly for filling. It is further desirable to improve the handling and / or movement of the pourable assembly within the filling device assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0028] The present disclosure can be embodied in many different forms, but is shown in the drawings and described in detail herein as specific embodiments on the understanding that the present disclosure is regarded as an exemplification and is not limited to the illustrated embodiments.

[0029] It will be understood that like or similar elements and / or components referred to herein may be identified by like reference numerals throughout the drawings. In addition, the drawings are only schematic representations of the invention, and it will be understood that some components may be distorted from the actual scale for the sake of clarity of the figures.

[0030] Next, referring to the drawings, particularly FIGS. 1 to 4, the entire filling device assembly according to the present disclosure is indicated by 10. This filling device assembly is also suitable for other types of containers and is not limited to any specific type of container, and can be used to fill various different fluid substances into a pouch assembly such as the pouch assembly 300. The fluid substances can be considered to include, inter alia, baby food and infant food, hummus, pudding, dairy beverages, nutritional drinks, and sports drinks.

[0031] In FIGS. 19 and 20, the pouch assembly 300 is shown as including a pouch 302, a spout 304, and a cap 320. The spout 304 is coupled to the pouch 302 and includes an upper portion 306, a lower portion 310, and a guide channel 308 therebetween. The lower portion 310 is fluid-tightly coupled to the pouch. The cap 320 is configured to screw around the corresponding thread of the upper portion. The guide channel is configured to fit into the lower channel 204 of the pouch moving mechanism 23 to facilitate the movement of the pouch assembly within the filling device assembly.

[0032] The filling device assembly 10 is shown as including a frame 12. The frame 12 defines a feeding zone for initially introducing an empty pouch into the filling device assembly and an outlet through which the filled pouch exits the filling device assembly. A plurality of different zones extend from the frame. These zones include a pouch feeding zone 20, a pouch preheating zone 22, a pouch sterilization zone 24, a pouch washing zone 26, a pouch filling zone 28, and a pouch capping zone 29. The pouch moving mechanism 23 sequentially directs the pouch to the plurality of different zones of the filling device assembly.

[0033] Referring further to FIG. 15, the pouch feeding zone 20 is configured to sequentially direct the pouch toward the first helical screw 200 and the second helical screw 202 of the pouch moving mechanism 23. The pouch feeding zone may obtain the pouch from a pouch holding rail loaded with the pouch. Such a rail may be sequentially and releasably attached to the pouch feeding zone 20 for sequential supply to the pouch moving mechanism 23.

[0034] Next, referring to FIGS. 5 to 7, the pouch preheating zone 22 includes a plurality of preheating nozzle assemblies such as the preheating nozzle assembly 30, a preheating nozzle mounting frame 32, a preheating actuator 34, a plurality of preheating vacuum nozzle assemblies such as the preheating vacuum nozzle assembly 36, a preheating vacuum nozzle frame 38, and a preheating vacuum actuator 39. In the illustrated configuration, there are two groups of four preheating nozzle assemblies each, for a total of eight preheating nozzle assemblies 30, and two preheating vacuum nozzle assemblies 36 belonging to a single group.

[0035] Each preheating nozzle assembly includes a first end 40 and a second end 42. A nozzle inlet 44 is positioned proximate to the first end 40. A spout engagement portion 46 is proximate to the second end. The spout engagement portion 46 includes an outer surface 48, a circumferential sealing rim 50, and a transverse groove 52. The spout engagement portion 46 terminates at an outlet 54. The spout engagement portion 46 is sized such that the circumferential sealing rim 50 sealingly abuts substantially corresponding to the inner surface of the spout 304 of the pouch assembly. As described herein, the transverse groove 52 provides a path for fluid to escape from within the pouch assembly. By allowing fluid to escape from the pouch assembly, the rate of rotation of the fluid within the pouch assembly is increased, and thus the effectiveness of the fluid and its action within the pouch assembly is improved (this improvement in effectiveness aids the preheated fluid and, with respect to other downstream zones, the sterilizing fluid and the cleaning fluid). Four transverse grooves are shown, but more or fewer grooves (all of which may have the same or different dimensions) may be disposed across the circumferential sealing rim. It will be understood that each of the eight preheating nozzle assemblies is substantially identical and is sequentially positioned at a predetermined interval within the pouch preheating zone.

[0036] In the illustrated configuration, the preheating nozzle mounting frame 32 is coupled to four preheating nozzle assemblies, and a biasing member 56 biases the preheating nozzle assemblies away from the mounting frame. In the illustrated configuration, there are two preheating nozzle mounting frames, each coupled to four preheating nozzle assemblies.

[0037] A preheating actuator 34 is coupled to the frame at one end and to the preheating nozzle mounting frame 32 at the other end. It will be understood that one preheating actuator, a total of two preheating actuators, is provided for each preheating nozzle mounting frame 32. The preheating actuator 34 is configured to move the preheating nozzle mounting frame between an upper position and a spout engagement position. In the upper position, the spout engagement portion 46 of the preheating nozzle assembly is spaced away from the pouch assembly. In the spout engagement position, the spout engagement portion 46 is positioned in an engaged state with the spout assembly.

[0038] Each preheating vacuum nozzle assembly 36 is shown as having a first end 62 and a second end 64. A nozzle outlet 66 is positioned proximate to the first end 40. A spout engagement portion 68 is proximate to the second end. The spout engagement portion 68 includes an outer surface 70 and a circumferential sealing rim 72. The spout engagement portion 46 terminates at an inlet 74. In the illustrated configuration, two preheating vacuum nozzle assemblies are shown, and it will be appreciated that the preheating vacuum nozzle assembly is similar to the preheating nozzle assembly 30, but a transverse groove is omitted from the preheating vacuum nozzle assembly.

[0039] In the illustrated configuration, the preheating vacuum nozzle frame 38 is attached to both preheating vacuum nozzle assemblies 36, and a biasing member biases the preheating vacuum nozzle assembly in a direction away from the preheating vacuum nozzle frame 38. The preheating vacuum actuator 39 has a first end coupled to the frame and a second end coupled to the preheating vacuum nozzle frame 38. Similar to the preheating actuator 34, the preheating vacuum actuator 39 includes two positions. An upper position away from the spout of the pouch assembly and a spout engagement position. The spout engagement portion of the preheating vacuum nozzle assembly engages the spout assembly.

[0040] It will be appreciated that variations are contemplated in which more or fewer preheating nozzle assemblies and preheating vacuum nozzle assemblies may be provided. In the illustrated configuration, and as described below, the filling device assembly is configured to intermittently feed two pouches at a time. Thus, the first pouch of a pair of pouches contacts the preheating nozzle assembly every other one from the first preheating nozzle assembly, and the second pouch of a pair of pouches contacts the preheating nozzle assembly every other one from the second preheating nozzle assembly. Thus, there are four separate contacts with one preheating nozzle assembly per pouch. This defines four preheating nozzle processes. Additionally, in the illustrated configuration, there are a pair of preheating vacuum nozzle assemblies. Thus, a pair of pouches receives a single preheating vacuum nozzle process.

[0041] It is further contemplated that each preheating nozzle assembly and each preheating vacuum nozzle assembly can be actuated by its dedicated actuator. In other configurations, it is contemplated that a plurality of pairs of preheating nozzle assemblies are actuated by a single actuator, or that all eight preheating nozzle assemblies are actuated by a single actuator.

[0042] It will further be understood that the nozzle inlet 44 of each preheating nozzle assembly can be coupled to a source of heated sterilizing air heated to a desired temperature, for example between 120°C and 220°C. Other temperatures are also contemplated as the heating temperature. Similarly, it will be understood that each nozzle outlet 66 of the preheating vacuum nozzle assembly 36 is coupled to a vacuum suction section, whereby a vacuum can be drawn.

[0043] Referring now to FIGS. 8 - 10, the pouch sterilization zone 24 is positioned within the filling apparatus assembly 10 following the pouch preheating zone 22. The pouch sterilization zone 24 includes a plurality of sterilization nozzle assemblies such as the sterilization nozzle assembly 80, a sterilization nozzle mounting frame 82, a sterilization actuator 84, sterilization vacuum nozzle assemblies such as the sterilization vacuum nozzle assembly 86, a sterilization vacuum nozzle frame 88, and a sterilization vacuum actuator 89. In the illustrated configuration, there are two groups of four sterilization nozzle assemblies 80, for a total of eight sterilization nozzle assemblies 80, and two sterilization vacuum nozzle assemblies 86 belonging to a single group.

[0044] The above components of the pouch sterilization zone 24 are substantially identical to the configuration of the pouch preheating zone 22, but the operation and purpose of the pouch sterilization zone 24 are different from those of the pouch preheating zone 22.

[0045] Each sterilization nozzle assembly includes a first end 90 and a second end 92. A nozzle inlet 94 is positioned proximate to the first end 90. A spout engagement portion 96 is proximate to the second end 92. The spout engagement portion 96 includes an outer surface 98, a circumferential sealing rim 100, and a plurality of transverse grooves 102. The spout engagement portion 96 terminates at an outlet 104. The spout engagement portion 96 is sized such that the circumferential sealing rim 100 sealingly abuts substantially corresponding to the inner surface of the spout 304 of the pouch assembly. As described herein, the plurality of transverse grooves 102 provide a path for fluid to escape from within the pouch assembly. It will be appreciated that each of the eight sterilization nozzle assemblies is substantially identical and is sequentially positioned at a predetermined interval within the pouch sterilization zone.

[0046] In the illustrated configuration, the sterilization nozzle mounting frame 82 is coupled to four sterilization nozzle assemblies, and a biasing member 106 biases the sterilization nozzle assemblies away from the mounting frame. In the illustrated configuration, there are two sterilization nozzle mounting frames, each coupled to four sterilization nozzle assemblies.

[0047] A sterilization actuator 84 is coupled to the frame at one end and to the sterilization nozzle mounting frame 82 at the other end. It will be appreciated that one sterilization actuator, a total of two sterilization actuators, is provided for each sterilization nozzle mounting frame 82. The sterilization actuator 84 is configured to move the sterilization nozzle mounting frame between an upper position and a spout engagement position. In the upper position, the spout engagement portion 96 of the sterilization nozzle assembly is spaced apart from the pouch assembly. In the spout engagement position, the spout engagement portion 96 is positioned in an engaged state with the spout assembly.

[0048] Each sterilization vacuum nozzle assembly 86 is shown as having a first end 112 and a second end 114. A nozzle inlet 116 is positioned proximate to the first end 112. A spout engagement portion 118 is proximate to the second end. The spout engagement portion 118 includes an outer surface 120 and a circumferential sealing rim 122. The spout engagement portion 118 terminates at an inlet 124. In the illustrated configuration, two sterilization vacuum nozzle assemblies are shown, and it will be understood that the sterilization vacuum nozzle assemblies are similar to the sterilization nozzle assemblies 80, but the transverse grooves are omitted from the sterilization vacuum nozzle assemblies.

[0049] In the illustrated configuration, a sterilization vacuum nozzle frame 88 is attached to both sterilization vacuum nozzle assemblies 86, and a biasing member biases the sterilization vacuum nozzle assemblies away from the sterilization vacuum nozzle frame 88. A sterilization vacuum actuator 89 has a first end coupled to the frame and a second end coupled to the sterilization vacuum nozzle frame 88. Similar to the sterilization actuator 84, the sterilization vacuum actuator 89 similarly includes two positions. An upper position away from the spout of the pouch assembly and a spout engagement position where the spout engagement portion of the sterilization vacuum nozzle assembly engages the spout assembly.

[0050] Similar to the preheating zone, in the illustrated configuration, the first pouch of the pair of pouches contacts the sterilization nozzle assemblies every other one from the first sterilization nozzle assembly, and the second pouch of the pair of pouches contacts the sterilization nozzle assemblies every other one from the second sterilization nozzle assembly. Thus, there are four separate contacts with one sterilization nozzle per pouch. This defines four sterilization nozzle treatments. Additionally, in the illustrated configuration, there are a pair of sterilization vacuum nozzle assemblies. Thus, the pair of pouches receive a single sterilization vacuum nozzle treatment.

[0051] Similar to the preheating zone, each sterilization nozzle assembly and each sterilization vacuum nozzle assembly can be actuated by a single actuator. Alternatively, the nozzle assemblies can be coupled in any combination such that a single actuator actuates multiple nozzle assemblies.

[0052] In the illustrated configuration, each nozzle inlet 94 of each sterilization nozzle assembly can be coupled to a hydrogen peroxide vapor source. By way of non-limiting example only, the concentration of hydrogen peroxide is greater than 30%, the evaporation temperature is higher than 235°F (about 112.8°C), and the dosage of hydrogen peroxide is more than 5 g / min. Of course, other concentrations, temperatures, and flow rates are also conceivable. The nozzle outlet 126 of the sterilization vacuum nozzle assembly 86 is coupled to a vacuum suction section, whereby it will also be understood that evacuation is possible.

[0053] Referring to FIGS. 11-13, the pouch washing zone 26 is positioned within the filling apparatus assembly 10 subsequent to the pouch sterilization zone 24. The pouch washing zone includes a plurality of washing nozzle assemblies 130, a washing nozzle mounting frame 132, a washing actuator 134, a washing vacuum nozzle assembly such as the washing vacuum nozzle assembly 136, a washing vacuum nozzle frame 138, and a washing vacuum actuator 139. In the illustrated configuration, there are a total of eight washing nozzle assemblies 130 positioned in two groups of four each and two washing vacuum nozzle assemblies 136 belonging to a single group.

[0054] The above-described components of the pouch washing zone 26 are substantially identical to the configuration of the pouch sterilization zone 24 and the pouch preheating zone 22, but the operation and purpose of the pouch washing zone 26 are different from those of the pouch sterilization zone 24 and the pouch preheating zone 22.

[0055] Each cleaning nozzle assembly includes a first end 140 and a second end 142. A nozzle inlet 144 is positioned proximate to the first end 140. A spout engagement portion 146 is proximate to the second end 142. The spout engagement portion 146 includes an outer surface 149, a circumferential sealing rim 150, and a plurality of transverse grooves 152. The spout engagement portion 146 terminates at an outlet 154. The spout engagement portion 146 is sized to sealingly abut generally corresponding to the inner surface of the spout 304 of the pouch assembly. As described herein, the plurality of transverse grooves 152 provide a path for fluid to escape from within the pouch assembly. It will be appreciated that each of the eight cleaning nozzle assemblies is substantially identical and is sequentially positioned at a predetermined interval within the pouch cleaning zone.

[0056] In the illustrated configuration, the cleaning nozzle mounting frame 132 is coupled to four preheating nozzle assemblies, and a biasing member 156 biases the cleaning nozzle assemblies away from the mounting frame. In the illustrated configuration, there are two cleaning nozzle mounting frames, and each frame is coupled to four cleaning nozzle assemblies.

[0057] A cleaning actuator 134 is coupled to the frame at one end and to the cleaning nozzle mounting frame 132 at the other end. It will be appreciated that one cleaning actuator, for a total of two cleaning actuators, is provided for each cleaning nozzle mounting frame 132. The cleaning actuator 134 is configured to move the cleaning nozzle mounting frame between an upper position and a spout engagement position. In the upper position, the spout engagement portion 146 of the cleaning nozzle assembly is spaced apart from the pouch assembly. In the spout engagement position, the spout engagement portion 146 is positioned in an engaged state with the spout assembly.

[0058] Each cleaning vacuum nozzle assembly 136 is shown as having a first end 162 and a second end 164. A nozzle outlet 166 is positioned proximate the first end 162. A spout engagement portion 168 is proximate the second end. The spout engagement portion 168 includes an outer surface 172 and a circumferential seal rim 170. The spout engagement portion 164 terminates at an inlet 174. In the illustrated configuration, two cleaning vacuum nozzle assemblies are shown, and it will be appreciated that the cleaning vacuum nozzle assemblies are similar to the cleaning nozzle assemblies 130, but without the transverse grooves being provided in the cleaning vacuum nozzle assemblies.

[0059] In the illustrated configuration, a cleaning vacuum nozzle frame 138 is attached to both cleaning vacuum nozzle assemblies 136, and a biasing member biases the cleaning vacuum nozzle assemblies in a direction away from the cleaning vacuum nozzle frame 138. A cleaning vacuum actuator 139 has a first end coupled to the frame and a second end coupled to the cleaning vacuum nozzle frame 138. Similar to the cleaning actuator 134, the cleaning vacuum actuator 139 includes two positions as well. An upper position away from the spout of the pouch assembly and a spout engagement position where the spout engagement portion of the cleaning vacuum nozzle assembly engages the spout assembly.

[0060] Similar to the preheating zone and the sterilization zone, in the illustrated configuration, the first pouch of the pair of pouches contacts the cleaning nozzle assemblies every other one from the first cleaning nozzle assembly, and the second pouch of the pair of pouches contacts the cleaning nozzle assemblies every other one from the second cleaning nozzle assembly. Thus, there are four separate contacts with one cleaning nozzle per pouch. Thereby, four cleaning nozzle treatments are defined. Additionally, in the illustrated configuration, there are a pair of cleaning vacuum nozzle assemblies. Thus, the pair of pouches undergoes a single cleaning vacuum nozzle treatment.

[0061] Similar to the preheating zone, each cleaning nozzle assembly and each cleaning vacuum nozzle assembly can be actuated by a single actuator. Alternatively, the nozzle assemblies can be combined in any combination so that a single actuator actuates a plurality of nozzle assemblies.

[0062] In the illustrated configuration, each nozzle inlet 144 of each cleaning nozzle assembly can be coupled to a sterile air source. The temperature of this sterile air can be a temperature between 120°C and 220°C. It will also be understood that the nozzle outlet 166 of the cleaning vacuum nozzle assembly 136 is coupled to a vacuum suction portion and can thereby be evacuated.

[0063] Referring to FIG. 14, the pouch filling zone 28 in the illustrated configuration includes a first filling valve 180 and a second filling valve 182. The first filling valve includes an inlet 184 and an outlet 186. The second filling valve includes an inlet 188 and an outlet 189. In the illustrated configuration, the two filling valves can be actuated simultaneously to fill two pouches simultaneously. In the illustrated configuration, the filling valves can further include a vacuum outlet so that a final evacuation of the pouch assembly can be performed prior to filling. Further, both filling valves can have a nitrogen gas source. Nitrogen gas can be used to expel any sterile air that may remain in the container after filling. Nitrogen gas has excellent performance against the deterioration of the fluid substance filled in the pouch assembly.

[0064] Continuing to refer to FIG. 14, the pouch capping zone 29 in the illustrated configuration includes a cap supply channel 190 and a capping assembly 194. The cap supply channel 190 includes a gravity supply channel. The gravity supply channel is configured to correspond to the shape of the cap so as to direct the cap towards the lower end 192. As will be described below, when the cap reaches the lower end, the cap is positioned such that the spout engages the cap and moves the cap from the cap supply channel above the spout.

[0065] The cap rotating assembly 194 includes a pair of cap engaging bits 196, 197. Each of the cap engaging bits 196, 197 is rotatably attached to a respective rotational actuator 198, 199. The cap engaging bits include a plurality of protrusions that fit into the recesses of the cap. When the cap engaging bits rotate, the cap rotates accordingly. It goes without saying that the shape of the cap engaging bits can vary according to the configuration of the cap, under the understanding that the cap engaging bits are configured to releasably engage with the cap and to be rotatably coupled to the cap in a releasable manner.

[0066] Next, referring to FIGS. 15 to 18 in combination with FIGS. 1 to 4, as described above, the pouch moving mechanism 23 moves the pouch assembly across the filling device assembly, particularly from the second end of the pouch feeding zone through the pouch preheating zone, the pouch sterilization zone, the pouch washing zone, the pouch filling zone, and the pouch capping zone. In the illustrated configuration, the pouch moving mechanism 23 includes two different regions. One region passes the pouch assembly from the second end of the pouch feeding zone through the pouch filling zone (i.e., until the pouch is filled). The other region passes the pouch assembly from the pouch filling zone through the pouch capping zone (including attaching the cap to the spout and securing the cap to the spout).

[0067] Specifically, the first region includes a pair of spiral screws that define a first spiral screw 200 and a second spiral screw 202, and a lower channel 204. The first spiral screw includes a first end 210, a second end 212, and a spiral groove 214. The second spiral screw includes a first end 216, a second end 218, and a spiral groove 220.

[0068] The first helical screw and the second helical screw rotate about parallel axes of rotation. These axes of rotation extend longitudinally through the filling device assembly and define the direction of movement of the pouch assembly together with the lower channel. The lower channel is disposed around a longitudinal axis parallel to the axis of rotation of each of the first helical screw and the second helical screw. This longitudinal axis extends generally below the axes of rotation of the first helical screw and the second helical screw and midway between these two axes of rotation. The channel is sized to slidably receive the pouch assembly, in particular such that the guide channel 308 can engage across the lower channel and is sized to be slidably movable along it from a first end to a second end. In the illustrated configuration, the configuration of the guide channel of the pouch assembly with respect to the lower channel is such that rotation of the pouch assembly with respect to the channel is prevented.

[0069] The helical windings are adapted to correspond to each other such that when both helical screws are rotating, both helical grooves fit exactly together. A plurality of portions of the helical groove can be enlarged to facilitate the passage of one nozzle of any one zone obstructed or interfering with the helical screw and engage with the outlet of each pouch assembly.

[0070] Since the upper portion 306 of the outlet of the pouch assembly engages the helical grooves 214, 220, rotation of the first helical screw and the second helical screw in opposite directions controllably translates the pouch parallel along the lower channel between the first end and the second end of the channel. It will be appreciated that the first helical screw and the second helical screw can be driven by an electric motor. The electric motor can be coupled to the helical screw via a gear train or the like.

[0071] Proximate to the second ends of the first helical screw and the second helical screw, a second region of the pouch moving mechanism is positioned. The second region includes a first linear moving assembly 206 positioned on one side of the pouch assembly, a second linear moving assembly 208, and a linear lower channel 209. The linear lower channel 209 generally comprises an extension of the lower channel 204 extending from the second end 224 of the lower channel 204 and generally includes dimensions similar to those of the lower channel 204.

[0072] The first linear moving assembly includes a pouch engaging member 226, a transverse actuator 228, and a longitudinal moving member 229. The pouch engaging member 226 includes a generally planar member having an inner edge provided with a plurality of receiving grooves 230. These receiving grooves 230 are spaced apart from each other (preferably, substantially corresponding to the distance between any two adjacent nozzles in these zones). In the illustrated configuration, a total of eight receiving grooves, such as the receiving grooves 230, are disposed along the inner edge.

[0073] Generally, the transverse actuator 228 is configured to direct the pouch engaging member 226 inwardly and outwardly, toward and away from the linear lower channel 209, on the first side of the linear lower channel 209. The longitudinal moving member is configured to direct the pouch engaging member longitudinally (i.e., parallel to the linear lower channel 209) toward the first end or the second end of the linear lower channel. In the illustrated configuration, the transverse actuator comprises a pneumatic actuator. Further, the longitudinal moving member comprises a linear actuator including a servo motor. The servo motor drives a toothed belt fixed to the pouch engaging member 226 to move the pouch engaging member 226. Thus, the pouch engaging member can move toward and away from the linear lower channel, along a path substantially parallel to the linear lower channel, or in a combination of both movements.

[0074] Similarly, the second linear movement assembly includes a pouch engagement member 232, a transverse actuator 234, and a longitudinal movement member 236. The pouch engagement member 232 includes a substantially planar member having an inner edge provided with a plurality of receiving grooves 238. These receiving grooves 238 are configured in a spaced-apart arrangement (similar to the receiving grooves 230). Similar to the receiving grooves 230, a total of eight receiving grooves 238 are provided along the inner edge of the pouch engagement member.

[0075] Similarly, the transverse actuator 234 includes a pneumatic actuator. The pneumatic actuator directs the pouch engagement member towards and away from the linear lower channel 209. Further, the longitudinal movement member 236 includes a linear actuator including a servo motor. The servo motor drives a toothed belt fixed to the pouch engagement member 232 to move the pouch engagement member 232. Thus, the pouch engagement member can move in both directions towards and away from the linear lower channel, as well as along a path substantially parallel to the linear lower channel, or in a combination of both movements.

[0076] The first linear movement assembly and the second linear movement assembly are movable independently of each other. That is, the pouch engagement member 226 and the pouch engagement member 232 are movable independently of each other and can engage separately or together with their respective pouch assemblies positioned along the linear lower channel.

[0077] Regarding the movement of one or a series of pouch assemblies passing through the filling device assembly from the pouch feeding zone to the pouch capping zone, the operation will be described. Although a single line (the line defined by the lower channel 204 and the linear lower channel 209, Fig. 15) is shown, it will be understood that the filling device assembly may have a plurality of lines positioned side by side within the same frame. For example, two parallel lines may be configured within the same frame, but a number greater than two is equally conceivable. In addition, although the pouch assemblies are considered to move through the filling device assembly in pairs, other configurations (such as a single pouch and more than three pouches) are also conceivable.

[0078] More specifically, referring to Figs. 1 to 4, a plurality of pouch assemblies are first supplied to the pouch feeding zone 20. Such pouch assemblies may be positioned on rails or the like, as is known to those skilled in the art. Once supplied, these pouch assemblies are sequentially directed towards the pouch preheating zone 22. More specifically, referring to Figs. 15 to 18, each pouch is sequentially directed towards the first end of the pouch movement mechanism and positioned at the first end of the lower channel 204. At the same time, the first helical screw and the second helical screw are positioned so as to accommodate the outlet in their respective helical grooves 214, 220. As the helical screws rotate about their respective axes of rotation, the interaction between the helical grooves and the outlets of the pouch assemblies biases the pouch assemblies along the lower channel. Similarly, additional pouch assemblies are sequentially directed towards the pouch preheating zone 22, one by one.

[0079] Referring to FIGS. 5 to 7, within the pouch preheating zone, the pouches advance in pairs. First, the first two pouch assemblies will encounter the first two preheating nozzle assemblies. When these pouches are properly positioned, each preheating actuator 34 is actuated to direct the preheating nozzle assembly towards the spout engagement position. As a result, the first two preheating nozzle assemblies engage with the spouts of the first two pouch assemblies, and the circumferential sealing rim engages in a substantially sealed engagement with the inner surface. Upon engagement, heated air is injected from the outlet of the preheating nozzle assembly into the pouch assembly. The pouch assembly expands as it is filled. Finally, excess preheating air exits the pouch assembly through the transverse groove at the spout engagement portion so as to cross the circumferential sealing rim and be discharged from the pouch assembly. This process continues for a predetermined time to raise the temperature of the pouch assembly.

[0080] Thereafter, the preheating actuator 34 returns to the upper position and disengages the preheating nozzle assembly from the pouch assembly. Once disengaged, the pouch moves in pairs towards the third and fourth preheating nozzle assemblies. Thereafter, this process is repeated. Heated air is injected from the outlet of each preheating nozzle assembly into each pouch assembly, and excess air is discharged from the pouch assembly through the transverse groove. After a predetermined time has elapsed, the actuator returns the preheating nozzle assembly to the upper position, and the two pouch assemblies are moved in pairs towards the fifth and sixth preheating nozzle assemblies. This process is repeated, and thereafter, the two pouch assemblies are moved in pairs towards the seventh and eighth preheating nozzle assemblies. This process is repeated again.

[0081] It will be understood that subsequent pouch assemblies enter the filling device assembly simultaneously in sequence and are subjected to the same multiple processes in the same order.

[0082] After the last preheating nozzle assembly, the pair of pouch assemblies are moved relative to the preheating vacuum nozzle assembly, and the preheating vacuum actuator 39 moves the preheating vacuum nozzle assembly to the spout engagement position. At such a point in time, vacuum evacuation is performed by the preheating vacuum nozzle assembly, and air is removed from the pouch assembly.

[0083] Referring further to FIGS. 8-10, the overall collapsed pouch assembly then moves relative to the pouch sterilization zone. There, a process very similar to the above-described process is sequentially performed by four pairs of sterilization nozzle assemblies 80. However, in the pouch sterilization zone, instead of the supply of heated air, the sterilization nozzle assembly supplies hydrogen peroxide vapor by each of four successive interactions with the pouch assembly. Excess hydrogen peroxide is discharged from the pouch assembly through the transverse groove of the sterilization nozzle assembly.

[0084] After four sterilization processes, these pouch assemblies move relative to the sterilization vacuum nozzle assembly. When the sterilization vacuum actuator is positioned at the spout engagement position, hydrogen peroxide vapor is completely discharged from the pouch assembly by vacuum evacuation. The overall collapsed pouch assembly is directed toward the pouch washing zone by the coordinated rotation of the double helical screws.

[0085] Referring further to FIGS. 11-13, in the pouch washing zone, similar to the previous zones, the pouch assemblies pass through four pairs of washing nozzle assemblies relative to each other. Each of the successive washing nozzle assemblies flushes away the hydrogen peroxide vapor remaining in the corresponding pouch assembly by washing the pouch assembly with sterile air. Excess sterile air is discharged from the pouch assembly through the transverse groove of the washing nozzle assembly. These pouch assemblies are subjected to the same process by each of the four pairs of washing nozzle assemblies. Finally, these pouch assemblies move relative to the washing vacuum nozzle assembly. There, the washing vacuum nozzle actuator is directed toward the spout engagement position. The washing vacuum nozzle assembly engages the spout of the spout assembly. Vacuum evacuation is performed by the washing vacuum nozzle assembly. The sterile air injected into the pouch assembly is removed by vacuum evacuation.

[0086] When the cleaning air is removed and the pouch assembly assumes an overall collapsed shape configuration, the pouch is directed towards the pouch filling zone. The vacuum steps at each of the intervals between the preheating zone and the sterilization zone, between the sterilization zone and the cleaning zone, and between the cleaning zone and the filling zone minimize the mixing of the gas from each of these zones with the gas of the subsequent zone, and it will be understood that such fluids are removed to a greater extent by the vacuum. Additionally, in each zone, the effectiveness of the fluid used in a particular zone can be improved by removing the fluid from the preceding zone. That is, the service fluid is not impaired by contamination from the fluid of the preceding zone.

[0087] Referring to FIG. 14, in the pouch filling zone 28, a first filling valve is coupled to the first pouch assembly of the two pouch assemblies, and a second filling valve is coupled to the second pouch assembly of the two pouch assemblies. A vacuum draw can first be performed to remove any remaining sterilizing air that may remain after the pouch cleaning zone or that may have returned after the cleaning vacuum nozzle assembly was detached from the pouch assembly. Thereafter, the fluid substance can be injected from the filling valve into the pouch assembly. The filling can be controlled by flow rate and time, or by volume, or by other means, to fill the pouch assembly with a desired amount of the fluid substance. After filling with the fluid substance, nitrogen gas can be injected into the pouch assembly to expel any air that may remain in the headspace.

[0088] Referring further to FIGS. 15 and 17, after filling, the pouch assembly has reached the second end of the helical screw and is directed towards the first end of the linear lower channel. At such a point in time, one of the first linear movement assembly 206 and the second linear movement assembly 208 is actuated so that the pouch assembly (eventually a plurality of pouch assemblies) is captured in one of the receiving grooves of the pouch engaging member, causing at least one pouch engaging member to face inward. When the pouch is received, each linear movement assembly is intermittently fed towards the second end of the linear lower channel in order to advance the pouch. These linear movement assemblies can be configured to operate sequentially. For example, the first pouch engaging member can engage the pouch assembly and intermittently feed the pouch assembly towards the second end of the linear lower channel. At such a point in time, the second pouch engaging member can engage the pouch assembly. Once engaged, the first pouch engaging member can disengage the pouch assembly and be intermittently fed towards the first end of the linear lower channel. Simultaneously, or almost simultaneously, the second pouch engaging member can intermittently feed the pouch assembly towards the second end of the linear lower channel. Next, the first pouch engaging member can then be actuated to engage the pouch assembly. At such a point in time, the second pouch engaging member can disengage. The second pouch engaging member can be intermittently fed in the reverse direction towards the first end of the linear lower channel. On the other hand, the first pouch engaging member intermittently feeds the pouch assembly towards the second end of the linear lower channel. This process can be repeated many times in order to sequentially move each pouch assembly. When the pouch assembly reaches the second end of the lower channel, it is introduced into the linear lower channel and passes through the pouch capping zone 29. Thus, when the pouch assembly is in the pouch capping zone, reliable engagement of at least one pouch engaging member of the first linear movement assembly and the second linear movement assembly is maintained, thereby substantially preventing unwanted movement of the pouch assembly in the pouch capping zone.

[0089] The transition from the first and second helical screws to the linear movement assembly allows for greater access to the pouring outlet, facilitating the attachment and tightening of the cap to the pouring outlet. This is achieved by the use of the linear movement assembly and the movement of the pouch from the rotating helical screw to the pouch engaging member. The pouch engaging member can direct the pouch assembly linearly along the linear lower channel.

[0090] Referring to FIG. 14, as each pouch assembly is intermittently fed past the cap supply channel 190, the pouring outlet of each pouch assembly sequentially reaches the lower end 192 of the cap supply channel. The cap is positioned at the lower end 192 of the cap supply channel by gravity feed. As the pouch moves past the cap supply channel, the engagement between the pouring outlet and the lowermost cap at the lower end of the cap supply channel is disengaged from the cap supply channel and positioned at the pouring outlet of the pouch assembly. When the cap is removed from the cap supply channel by the pouch assembly, another cap is gravity-fed to the lower end of the cap supply channel in preparation for engagement with a subsequent pouch assembly. The cap is sterilized before reaching the lower end of the cap supply channel. Such sterilization can be performed while the cap is within the cap supply channel or before the cap is positioned in the cap supply channel.

[0091] Next, a plurality of pouch assemblies with caps placed on the spouts are directed towards the pair of cap-turning assemblies by the coordinated operation of at least one pouch engagement member 226. When the pouch assemblies are properly positioned relative to the pouch-turning assemblies, the cap-turning assemblies are actuated to releasably engage cap engagement bits 196, 197 with the caps positioned on the spouts of the pouch assemblies. Next, the cap engagement bits are rotated by rotary actuators 198, 199 so as to engage the threads of the caps with the threads of the spouts and tighten the caps onto the spouts. When completed, the pouches are again intermittently fed forward (again in pairs) beyond the second end of the linear lower channel. Thereafter, the pouch assemblies exit the filling device assembly. In the illustrated configuration, an inclined chute is positioned at the second end of the linear lower channel to direct the filled pouch assemblies controllably from the filling device assembly for further processing.

[0092] It will be appreciated that the above description provides an explanation of the operation of the illustrated configuration. Further, for example, although the pouch assemblies are shown as being processed in pairs, several variations are conceivable, such as being processed individually or in numbers greater than two. Additionally, within a single filling device assembly, multiple lines may extend parallel to each other. Further, the timing of each step is typically such that the pouches advance uniformly in pairs, but it is conceivable that some steps may take longer than others and that there may be a residence time during which some pouch assemblies are processed before the pouches move within the filling device assembly. Other variations are similarly conceivable.

[0093] It will further be appreciated that the upper ends of the pouch assemblies can be maintained within a sterile environment throughout the filling device assembly. Here, the sterile zone can be defined through each of a pouch sterilization zone, a pouch washing zone, a pouch filling zone, and a pouch capping zone. The sterile environment can be maintained, inter alia, by a positive pressure of sterile air. Additionally, the caps of the pouches can be sterilized before heading towards the pouch capping zone.

[0094] The foregoing description is only illustrative and explanatory of the present disclosure and does not limit the present disclosure, except where the appended claims so limit it. Those skilled in the art who read this disclosure will be able to make changes to the content of this disclosure without departing from the scope of this disclosure.
