Definitions
- the present invention relates to a ferris wheel-type vacuum packaging system and method.
- Vacuum packaging in heat sealable plastic bags is a conventional way of packaging food products such as meat and cheese, and involves placing the food item in a bag having a bag mouth, and then evacuating air from the bag through the bag mouth and collapsing the bag about the contained food product. The bag is then heat sealed in its evacuated condition so the food product becomes encased in a generally air-free environment. Often the bag is heat shrinkable, and after the heat sealing step, is advanced to a hot water or hot air shrink tunnel to induce shrinkage of the bag around the food product.
- Vacuum packaging machines of a known type include a vacuum chamber arranged to receive an unsealed loaded bag and operable to perform a vacuum sealing operation on the loaded bag. After loading and closing the vacuum chamber, the vacuum sealing operation typically includes vacuumization, sealing the mouth of the vacuumized bag, and reintroducing air into the chamber. The chamber is then opened and the vacuum chamber is unloaded. Sometimes, the resulting package may then be conveyed to a heat-shrinking unit, typically a hot water tunnel or a dip tank, to shrink the bag around the product.
- a heat-shrinking unit typically a hot water tunnel or a dip tank
- vacuumization step typically takes at least 20 to 30 seconds. During this time, the only step which can be taken is to prepare the next packages for loading into the vacuum chamber, for example by conveying them onto an in-feed conveyor. Accordingly, the vacuum packaging machine may cause a bottleneck in the overall packaging process.
- Rotary vacuum packaging machines which include a series of vacuum chambers and chain driven product platens. In operation, the platens move from a loading position, thorough a vacuum/sealing/venting stage, to an unloading position, and finally back to the loading position.
- One disadvantage of these machines is that they have a large footprint, and therefore take up a large amount of floor space.
- a further problem is that these machines generally require manual loading and bag spreading and are thus difficult to incorporate in a fully automated process.
- the rotary system is not an in-line process. Typically, an unsealed package is loaded in-line, but unloaded as a vacuumized, sealed package at a right angle to the in-feed direction. This often disrupts a "streamlined" product flow through the packing area.
- a conveyor apparatus configured to unload a vacuumized, sealed package from each platen conveyor, and to load an unsealed package onto each platen conveyor, in a linear path, the conveyor apparatus comprising
- a ferris wheel-type vacuum packaging apparatus comprising at least three radially arranged vacuum chambers each linked with a respective platen assembly, each chamber and platen assembly rotatable about a central horizontal axis disposed parallel to the linear path of the conveyor apparatus, the ferris wheel-type vacuum packaging apparatus operable in a vertical plane of rotation disposed perpendicular to the linear path of the conveyor apparatus.
- a method of vacuumizing and sealing a plurality of unsealed packages comprises providing a plurality of vacuum chambers each linked with a respective platen assembly, each platen assembly comprising a platen and a platen conveyor, each vacuum chamber and platen assembly arranged to receive an unsealed package and operable to perform a vacuumizing and sealing operation on the unsealed package, characterized in that the method of vacuumizing and sealing a plurality of unsealed packages comprises

- the three chamber slip ring assemblies 82, 84 and 86 are mounted on the center axis of each of vacuum chambers 32, 34, and 36 respectively.
- Internal to a slip ring associated with each slip ring assembly is a series of circular tracks and brushes that allow continuous connection of electrical signals and power through a pivot joint that rotates 360 degrees.

- Main slip ring assembly 80 communicates with first slip ring assembly 82, second slip ring assembly 84, and third slip ring assembly 86, to provide positive air pressure and electrical power and control signals to drive the platen motor, seal wires, pneumatic valves and one or more air cylinders 162, 164 and 166 in each of vacuum chambers 32, 34, and 36 respectively, in order to operate a heat sealing assembly, including a seal bar, clamp, and cutting device disposed in each respective vacuum chamber.
- the heat sealing assembly within each vacuum chamber of the present invention is of a type well known in the art, e.g. as disclosed in US Patent No. 7,296,390 (Koke et al.), this patent incorporated herein by reference in its entirety.

- Drive plate 102 includes first drive plate armature 1 12, second drive plate armature 1 14, and third drive plate armature 1 16.
- Slave plate 103 includes first slave plate armature 122, second slave plate armature 124, and third slave plate armature 126.

- a first alternative platen-stabilizing device 131 includes a central gear 140 driven by central drive shaft 70.
- a first terminal gear 142 is shown interconnected to first vacuum chamber 32; second and third terminal gears 144 and 146 are suitably connected to second and third vacuum chambers 34 and 36 respectively (not shown in Figures 19 or 20).
- Rotary motion is imparted to the three terminal gears 142, 144, and 146 by means of first intermediate gear array 143, second intermediate gear array 145, and third intermediate gear array 147 respectively.
- a second alternative platen-stabilizing device 151 shown in Figs. 1 to
- Device 151 includes a first timing belt extension 152, a second timing belt extension 154, and a third timing belt extension 156.
- Device 151 is in one embodiment a single belt with the extensions as shown.
- the vacuum packaging system 10 would typically be located
- a fixed input conveyor or other suitable device would deliver unsealed packages to the in-feed conveyor 14.
- the packages are oriented such that the unsealed portion of each package is trailing.
- Apparatus 12 and apparatus 30 operate in a synchronized manner.
- An electronic control system such as a programmable logic controller or other suitable control system controls operation and synchronization of the different operations and functions that occur within apparatus 12 and apparatus 30 by means of suitable programming of the control system .
- These operations include rotationally advancing a platen assembly, having a vacuumized and sealed package on the platen conveyor thereof (previously loaded as an unsealed package onto the platen conveyor) to an
- unloading/loading position located between the in-feed and out-feed conveyors; unloading the vacuumized and sealed package from the platen conveyor onto the out-feed conveyor; loading (simultaneously with or subsequent to the unloading operation) an unsealed package from the in-feed conveyor onto the platen conveyor; closing a vacuum chamber onto the loaded platen conveyor; and rotationally advancing the vacuum chamber and associated platen assembly, including the loaded platen conveyor, a predetermined distance away from the unloading/loading position to a first intermediate position.
- the apparatus 30 pauses to allow a second
- a first and second intermediate position are defined in the rotary cycle.
- Figure 21 there are two interdependent timing cycles.
- the inner circle represents the load/unload and rotate cycle
- the outer ring shows the chamber cycle of closing the chamber, vacuumizing, sealing, cooling and venting and opening the chamber.
- the two cycles are balanced, to the extent that the vacuum cycle of each chamber must be completed in the time it takes for apparatus 30 to complete one rotation. Since the vacuum system is shared between the three chambers, the speed of rotation is timed to allow three chambers to be adequately evacuated in the time it takes for apparatus 30 to rotate once.
- the arrival of each vacuum chamber and associated platen assembly to the location where package loading/unloading takes place does not necessarily initiate the vacuumizing/ sealing operation.
- the two operations are independent to the extent that e.g. vacuumization can start as soon as the vacuum chamber is closed onto the platen assembly, i.e. before the chamber arrives at the first intermediate location.
- packages can be present in one, two, or all three of the vacuum chambers 32, 34 and 36, the packages disposed on any or all of platen conveyors 42, 44 and 46
- Each package is in some state ranging from an unsealed package when first loaded onto a platen, to a vacuumized and sealed package at a later stage in the rotary cycle before the package is unloaded from the platen.
- packages are in one embodiment simultaneously being loaded, vacuumized, sealed, and
- system 10 can optionally be operated in a mode in which, after a first unsealed package is loaded onto a first platen conveyor, the system will rotate apparatus 30, simultaneously resulting in rotational advancement of a platen assembly, having a second platen conveyor, to the loading/unloading position where any vacuumized sealed package present can be unloaded from the second platen conveyor.
- the system will pause in this state and will not load the second platen conveyor until a second unsealed package is disposed on the in-feed conveyor.
- a suitable sensing device (not shown) indicates that condition, the unsealed package will be loaded on the second platen conveyor and apparatus 30 then resumes rotation.
- the conveyor apparatus 12 operates to move packages in a linear path from right to left
- the ferris wheel-type vacuum packaging apparatus 30 operates to move packages in a rotational path in a counterclockwise direction as viewed from the right side (drive motor 90) of the drawings.
- the rotational path of apparatus 30 is in a vertical plane substantially perpendicular to the linear path of the packages and conveyors of apparatus 12.
- vacuumized and sealed package 22 containing a meat cut is disposed on platen conveyor 44 housed in vacuum chamber 34 (see Figs. 1 to 3).
- platen assembly 39 including platen conveyor 44 drops by gravity, the drop suitably dampened by any appropriate dampening device such as a pneumatic cylinder (not shown) until a platen arm (not shown, but see platen arm 52 in Figure 7) catches at detent 48 (see the sequence of Figs. 9 and 10).
- Platen assembly 39, including platen conveyor 44 thus temporarily separates spatially from vacuum chamber 34 (see Figs. 3 and 4). Chamber 34 remains in this open state until the
- a vacuumized and sealed package 22 is advanced from the platen conveyor onto out-feed conveyor 16 (see Figure 4) by activating the platen conveyor, and unsealed package 24 is advanced onto now-vacated platen conveyor 44.
- An optional bridging member 20 can be used to facilitate advancing and loading an unsealed package onto a platen located at the unloading/loading position.
- a telescoping conveyor 20 extends from below in-feed conveyor 14 to bridge the gap between the downstream end of in-feed conveyor 14, and the platen to be loaded, so as to facilitate loading of an unsealed package onto the platen.
- Conveyor 20 can be an extension of in-feed conveyor 14, a discrete member, or any other component suitable to bridge the gap between the in-feed conveyor and the platen. After loading the package, conveyor 20 can be retracted.
- the in-feed, out-feed, and platen conveyors are each driven by a suitable motive device such as a drum motor.
- Vacuumized and sealed package 22 can be manually or automatedly packed off into a shipping container or sent to another station for further processing, such as a hot water shrink tunnel.
- System 10 can optionally include a scrap removal device 28 to remove any cut-off portions (scrap) of packaging material located in a vacuum chamber or on a platen after a package has been vacuumized and sealed, and when the platen conveyor carrying the package has been advanced to the unloading/loading position located between the in-feed and out-feed conveyors.
- Device 28 can include e.g. any combination of an air curtain and/or suction, and be located at any suitable location near the
- the vacuumization/sealing cycle then initiates and vacuum chamber 34 and associated platen assembly 39 advance rotationally to a first intermediate position.
- the rotational movement of chamber 34 and platen assembly 39 necessarily causes equivalent rotational movement of chamber 36 and associated platen assembly 40 (not shown), and chamber 32 and associated platen assembly 38 (not shown).
- chamber 34 and platen assembly 39 reach the first intermediate position
- chamber 32 and associated platen assembly 38 reach a second intermediate position, and any remaining vacuumization, sealing, and cutting is done to produce a vacuumized and sealed package on platen conveyor 42 in vacuum chamber 32.
- vacuumized and sealed packages are unloaded onto out- feed conveyor 16, and unsealed packages are loaded onto a platen

- Each chamber can optionally include a puncturing device which is operable to puncture at least one aperture in the package adjacent the heat seal assembly, so that as each vacuum operation is performed, air is forced out of the package through the punctured aperture(s) prior to heat sealing.
- the puncturing device may comprise e.g. a plurality of piercing knives.
- an electrical current is applied to the heat seal bar to heat seal the package.
- the package is cut by a suitable cutting device such as a serrated knife to shear the scrap portion of the package between the heat seal and the end of the package, air is introduced back into the chamber, and the chamber is opened as described above to unload the vacuumized, sealed package, and load an unsealed package; and the packaging cycle repeats.
- each vacuum chamber further includes a puncturing device which is operable to puncture at least one aperture in an unsealed package adjacent the location in the package where a heat seal is to be made, such that as each vacuum sealing operation occurs, air is forced out of the package through the punctured aperture(s) prior to heat sealing.
- the puncturing device may comprise a plurality of piercing knives.
- the heat seal bar and anvil are positioned in each vacuum chamber transversely to the linear path of the conveyor apparatus, enabling each package to be loaded into each chamber with its unopened end transverse to the linear path.
- Electrical power is supplied to the heat sealing assembly of each vacuum chamber through a slip ring assembly that includes a spring brush that rides on a track that provides power to each vacuum chamber.
- the inner circle shows vacuum chamber loading and rotating cycles for a three chamber system; the outer circle shows the full cycle of a given vacuum chamber.
- the other chamber cycles are rotated 120°. Shown are representative times based on 1 .4 seconds rotation and 1 .6 seconds product loading. Actual loading time is about 2 seconds, taking into account about 0.4 seconds for the platen to drop from its associated vacuum chamber, and subsequently reclose after loading. With each chamber's timing rotated 120 degrees a single vacuum system can be shared by the three chambers.
- packaging apparatus can further comprise a platen-stabilizing device.
- This device functions to stabilize and hold each platen assembly in a horizontal plane throughout the rotation of apparatus 30. This in turn stabilizes each package during the vacuumization/ sealing operation, and provides for a smooth transition that facilitates the accurate placement of the unsealed end of each unsealed package over a respective seal bar.
- the platen-stabilizing device 101 includes a drive plate 102 driven by central drive shaft 70 powered by drive motor 90, and a slave plate 103.
- the operative rotary motion of apparatus 30 is counterclockwise as viewed in Figs. 15 to 18, and the figures are shown in regressive sequence, i.e. with Fig. 18 showing the apparatus at a first position, Figure 17 showing the apparatus at a position somewhat advanced from the first position, etc.
- the drive plate is connected to and drives slave plate 103 by a suitable mechanism, such as internal/external gears, so that rotational movement of the drive plate causes concomitant rotational movement of the slave plate.
- the armatures of the drive plate are each connected in pivotable fashion to a respective vacuum chamber, and armatures on the slave plate are connected by a suitable linkage to corresponding armatures on the drive plate. More generally, the number of armatures on each of the drive and slave plates will correspond with the number of vacuum chambers present in the system.
