The present invention generally relates to methods and systems including transportation units equipped with container handling units for processing packages. More particularly, the present invention relates to methods, systems and related machines with container handling units for transferring and orienting individual primary packaging containers.
For handling, treating, loading/unloading and performing other such processing steps e.g. filling, rinsing, capping, labelling, inspecting, on primary packaging containers, many processing methods, systems and related architectures have been conventionally executed. Such processing systems generally include one or more transportation units equipped with conventional means of handling the packaging containers, and thereby move and establish and maintain the pitch and velocity of the packaging containers from one place to another, or one machine to another, or one conveyor to another conveyor etc.
A general problem of the conventional architectures for primary containers is that they repeatedly gain and then give up individual control of the primary containers, cycling repeatedly between periods of buffer, bulk (en-mass), multi-lane, single file handling and then transitioning via a timing or pitch setting device such as an infeed scroll (worm) to individual primary container handling through the process at fixed pitch. The latter involves hand-off from the infeed timing device, such as a scroll (worm) to typically star wheels and guides for infeed, handling through and outfeed from the primary container processing machines, such as rotary cleaning or rinsing equipment, liquid filling machines, capping and labelling machines.
Scroll (worm), star wheel and guide architectures in container handling process systems are usually bulky, especially for high capacity machine, with large foot prints, and have complex machine structures and drives. Further, such scroll, star wheel and guide architectures may be challenging for personnel to access various parts or components of the processing machines, occupy more space and do not allow ease in retrieval or changing of parts
A second general problem of conventional primary container handling systems, such as scrolls (worms) star wheels and guides, is that they are unable to differentiate between various sizes and shapes of primary containers. As a consequence, the changing of parts becomes a necessary step in reconfiguring the processing systems, for each different diameter, skirt and/or shoulder height and shape of primary packaging container, resulting in lost production time and impacting productivity.
Further, an additional disadvantage, particularly related to scroll, star wheel and guide architectures, is that the timing scrolls (or worms) tend to slide over the packaging container surfaces while handling them. This may result in spoiling the surfaces (especially surface treated, textured surface finishes such as etching (frosting)), scratching the surface or spoiling the labels etc. on the surfaces, especially if grit or glass fragments have become embedded in the surfaces of the container handling change parts. In addition, line pressure queuing, entry into and handling by scrolls (worms) and star wheels and guides often results in high impact events, shocks and light through heavy loading of container to container and/or container to container handling part contact which limits attempts to reduce the wall thickness and hence the light weighting of containers.
In an attempt to replace star wheel based infeed and outfeed configurations for primary containers, US2013026005A1 provides a transporting apparatus comprising a transporting path which has its entire length arranged between a first and second container-handling arrangement and along which the containers can be transported by transporting elements such as clamps, wherein the pitch and pace of the transporting elements compensate for a difference in speeds of transportation of the containers in the first and second container-handling arrangements.
In the above attempt, although transporting elements are synchronized with the pitch and pace of first and second container-handling arrangements, the transporting elements are still unable to differentiate between various sizes and shapes of various packaging containers.
A third general problem in conventional primary container process is that, in case a processing step requires a particular primary container orientation or relative position different from the orientation or relative position at the infeed, for example labelling, complex tooling is required within the primary container processing machine to obtain the required orientation or relative position at capacity.
Considering the above, it is a first objective of the present invention to provide a flexible, efficient, high capacity, space saving, productivity enhancing solution which can process a wide range of primary packaging types, shapes and sizes and which eliminates the need for change parts.
Further, it is an objective of the present invention to remove operational constraints in terms of firm but gentle primary container handling, manipulation, pitch and pace synchronized transportation, orientation, positioning and movement, to, through, opposite, between and out of a process station and/or multiple process stations, be they static or dynamic (capable of performing the process while in synchronized motion and executing the process while in transit).
It is also an objective of the present invention to provide a programmable, recipe driven, dynamic handling system that can implement one or more adaptable container handling units in one or more processing operations depending on the type of products to be processed or operated upon.
It is also an objective of the present invention to provide an overall processing system which is compact, adaptive, coupled with digitalized solutions, and which eliminate the need for primary container specific change parts.
It is an objective of the present invention to provide smart, adaptive tooling for primary container handling which are easily optimizable via programming to realize software driven flexibility in the overall processing machine.
It is an objective of the present invention to achieve nimble flexibility at capacity for an efficient processing of an exceptionally wide range of primary packaging container types, shapes, sizes, formats and assembly sequences, including the handling of non-circular cross section primary containers, via synchronized, adaptive container handling units in pitch optimized, motion-controlled transit.
It is an objective of the present invention to provide packaging and treatment machines for treating individual primary containers. A consequence of individual treatments is further also that container to container contact during transfer and/or processing may be reduced, or even eliminated, that scroll (worm) and star wheel and guide configurations may be avoided, and therefore that the containers are not subject to impacts and extreme forces due to shocks, that forced container to container contact is eliminated, that handling forces are significantly reduced overall and thus all the associated damage and spoilage avoided associated with pressure, impact and shear forces are eliminated. Achieving this would enable progress in light weighting the containers as part of measures to lower packaging material costs, reduce material consumptions and make advancements in sustainability.
Additional objective of the invention is to remove the throughput, range, inefficiencies and operational constraints of traditional processing machinery and systems to overcome restrictions in packaging design and limited range of styles and formats offered by conventional, commercially available solutions.

Further, the mover or tile 106 may be magnetically coupled with the transportation unit 104 in a contactless manner. In this embodiment, the transportation unit 104 is also inductively controlled and may have electrical coils, while the mover 106 may be equipped with a permanent magnet for creating an electromagnetic field between the transportation unit 104 and the mover 106. Therefore, the mover 106 moves freely, in an independent motion over the transportation unit 104 under the effect of electromagnetic forces generated due to the electromagnetic coil in the transportation unit 104 and the permanent magnet in the mover 106. In another embodiment of the present invention, the mover 106 is attached with the transportation unit 104, and the transportation unit 104 drives the mover 106 implementing a movement system, such as a linear drive motor, or independent cart, or slides, or tracks, or any other type of driving means adapted to curvilinearly propel the mover in an independent and controlled way.
In an embodiment, the transportation unit 104 may be implemented with inductive cables from which inductive power is transmitted via the movers or levitating tiles 106 to the container handling units 108.
In an embodiment in accordance with the present invention, the processing system 100 may include at least one primary container processing station 102 and a transportation unit 104. The primary container processing station treats (eg. labels, inspects, etc.) primary containers which are individually 3-dimensionally transported and rotated by the container handling units 108.

The controlling unit 114 controls the 6-degrees of freedom, synchronized movement of the container handling units 108 relative to that of the main primary container conveying unit 102, or relative to that of the primary container processing station.
In an embodiment for wireless operation control of the mover and/or levitating tile 106 and the container handling unit 108, the mover and/or levitating tile 106 is equipped with a wireless client (telecommunication transmitter/receiver) with antenna for wireless communication via one or more of the communication protocols stated above. Each transportation unit 104 of the mover and/or levitating time 106 and the container handling unit 108 may form a dedicated wireless network within which the mover and/or levitating tile 106 and the container handling unit 108 and the transportation unit 104 may be wirelessly controlled via a data transmission, radiating, leaky cable following the closed loop, virtual closed loop or path of the movers and/or the levitating tiles. Further, in an embodiment, the container handling unit 108 may be independently wirelessly controlled within their own dedicated wireless network.
The components of the processing system 100 communicate bi-directionally with the controlling unit 114 via the communication channel 112, for example a communication fieldbus 112. The controlling unit 114 is installed with a software application 116 that monitors, controls and optimizes operations of the overall processing system 100, including the transportation unit 104 with the movers and/or levitating tiles 106 and the container handling units 108, along with the main primary container conveying unit 102 and/or the primary container processing station/s.
Further, the software application 116, in communication with one or more feedback sensors, may also detect a current position and arrangement of the handling mechanism of the container handling units 108, and may signal the container handling units 108 to adapt or change the current position, route and/or arrangement of the handling mechanism according to the size, shape and design of the primary container and/or the state of other primary containers in traffic and/or the state of one or more of the process stations.
Further, in an embodiment, the transportation unit as a whole 104 is moveable in multiple degrees of freedom with respect to an adjacent primary container transportation unit or processing station 102. The transportation unit 104 may be able to move within six degrees of freedom, relative to the adjacent primary container transportation unit 102 or relative to a primary container processing station, for performing transportation and rotation operations. In an embodiment, the transportation unit 104 is able to translate along, or incline, or to tilt, or to rotate around, one or more of the X, Y, Z axes (pitch, yaw, and roll) and all combinations thereof.
In an embodiment, the transportation unit 104 is able to move along and/or rotate about a vertical axis (Z), e.g. variability in height relative to the adjacent primary container transportation unit or processing station 102, along and/or rotate about a horizontal axis (X), e.g. variability in position in a direction parallel to the adjacent primary container transportation unit or processing station 102 machine direction, and along and/or rotate about a second horizontal axis (Y), e.g. variability in position in a direction perpendicular to an adjacent primary container transportation unit or processing station 102 or processing station machine direction. The transportation unit 104 in the processing system 100 may be closed loop or virtual closed loop or otherwise recirculating system either in series, parallel or in a swarm effect, and not necessary but preferably independent motion controlled cart (mover) (e.g. Linear Drive) and/or levitating tile based.
In an embodiment, one of the clamping or gripping means 202 in the configuration 200 of the container handling unit 108 is attached at the bottom of the container handling unit 108 in a way to support the primary container 110 from its bottom, or to place the primary container 110 over this clamping or gripping means 202. Thus, it may be appreciated by a person ordinarily skilled in the art that the clamping or gripping means 202 can be attached at any position in the container handling unit 108 for handling the primary container 110 from anywhere in its body and its bottom.
Further, the container handling units 108 also include a driving mechanism to control and drive the clamping or gripping means 202. The driving mechanism may be a driving motor. Also, the driving mechanism can be wirelessly controlled via the controlling unit 114, to, in turn, wirelessly control the container handling units 108. The inductive power driving the transportation units 104 is transmitted via the movers 106 to the container handling units 108, and eventually to the clamping means 202 via the driving mechanism.
In an embodiment, the processing system 100 includes two transportation units 104 facing opposite to each other, and where at least one of the transportation units 104 is installed with the container handling units 108 of
It may also be apparent to a person ordinarily skilled in the art, that in the above exemplary environment, the two transportation units 104 may be inclined to each other or to the adjacent primary container transportation unit 102 at any angle including 0°, depending on the requirement in the processing system 100, without deviating from the meaning and scope of the present invention.
It should be noted, that the clamping means 202 of the container handling units 108 are highly flexible, adaptable and dynamically controlled using its sensing mechanism with the controlling unit or driving mechanism, which means the clamping means 202 may adapt and control its handling mechanism to handle/grip/hold/or otherwise temporarily attach to any type and size and shape of primary container 100, for example different sizes and shapes of bottles, cans, boxes, etc. It also should be noted that the driving mechanism may rotate or spin the clamping means 202 that, in turn, rotates or spins the primary container 110 in any angle, in any dimension, or in any plane. For example, the driving mechanism may rotate or spin the clamping means 202 that, in turn, rotates the primary container 110 at a required angle.
Specifically, the container handling unit is configured to translate the primary container in an X direction. The X direction may be a horizontal axis, which may be parallel to a machine direction. Translation in the X direction may be enabled using a linear motor system. For example comprising linear movers 303A mounted on a stator rail 303B forming part of the container handling unit 108.

Each of the above-described movements can be executed and controlled independently from the other movements. Additionally, the extent of each movement can be continuously varied. That is, the user can select the extent of each movement from a continuous range, rather than being forced to select from a limited number of discrete options.
Each clamping or gripping means 302 is moveable fixed, preferably on rail mounted movers integrated in the container handling unit, and is adapted to individually translate and rotate each primary container. The latter configuration may enable picking a number of primary containers and grouping or re-grouping and/or orientating it within the container handling unit while transporting and before dropping. In other examples the container handling unit 108 may comprise only a single gripper to handle a single primary container.
The exemplary configuration of the container handling unit 108 with the clamping means 302 is suitable for handling and transporting the primary container, such as the bottle 110, by embedding the container 110 from the top. The container handling unit 108 in such configuration may also include a driving mechanism, such as a driving motor. The driving mechanism may rotate or spin the clamping means 302 that, in turn, rotates or spins the primary container 110 in any angle, in any dimension, or in any plane. For example, the driving mechanism may rotate or spin the clamping means 302 that, in turn, spins the primary container 110 upside down.
Because the clamping means 302 is highly flexible and adaptable and dynamically controlled, any type, size and shape of the primary container 110 can be handled from the top implementing the clamping means 302.
The container handling unit 108 also includes articulating tooling which can perform translation and/or rotation operations on the primary container 110. In this embodiment, a tool may be a craw or finger type gripping means, which is controlled by a driving mechanism, or a driving motor. The articulation is controlled by a driving mechanism, or a driving motor.
The driving inductive power driving the transportation units 104 is transmitted via the movers 106 to the container handling units 108, and eventually to the craw type tool via the driving mechanism.
The articulated tooling in this embodiment of the container handling unit 108 may be suitable for performing transportation and rotation operations such as including and not limited to translating, tipping, inclining, inverting, or raising, or declining the primary container 110. For example, the craw or finger type tool with the driving mechanism is suitable for tipping of the primary container 110.
In an embodiment, for an infeed turn of the transportation unit 104, at an outer most point (at outer curve) during the infeed turn, the container handling unit 108 and the movers 106 are inclined at different angle with respect to the transportation unit 104. At this point, the mover 106 turns according to the outer curve of the transportation unit 104 for traversing the same curve as traversed by the transportation unit 104, while the container handling unit 108 is horizontally positioned in the horizontal plane parallel to the plane of movement of the primary container 110. Due to this change in orientation of the container handling unit 108 to be in parallel plane of the moving primary container 110, the clamping means is horizontally positioned relative to primary container 110 and is able to properly grip the primary container 110 from the neck/collar. Whereas, at an inner point (at inner curve) during the infeed turn, the difference between the inclination of container handling unit 108 and the inclination of movers 106 with respect to the transportation unit 104 has reduced than the difference between the inclinations at this point, and the container handling unit 108 is maintain the orientation according to the plane of movement of the primary container to grip the primary container 110 firmly at the curve of the transportation unit 104. A benefit thereof is for example that the primary container hangs vertical while the mover negotiates radii and inclinations changing the elevation of the primary container. The pivot action may be motion controlled or simply act under the influence of gravity on the mass of the primary container, if the inclination for elevation or lowering is vertical.
It may be apparent to a person ordinary skill in the art that the processing system 100 may also pick the containers from a higher elevation of one main primary container conveying unit and lower and drop the containers to a lower elevation of other main primary container conveying unit.
Thus, advantageously, the container handling units 108 mounted on the independently controlled movers 106 are able to perform one or more translation and/or rotation operations such as gripping from any directions or sides of the primary container 110 and moving in multiple degrees of freedom, such as gripping and rotating in any angle, or gripping and lifting or lowering in Z axis relative to the adjacent primary container transportation unit or processing station 102, or such as gripping and moving closer or far from a plane along a horizontal axis (Y) e.g. variability in position in a direction perpendicular to the adjacent primary container transportation unit 102 machine direction, or such as gripping and moving in or opposite to the adjacent primary container transportation unit 102 machine direction, i.e., along a horizontal axis (X). In addition, the container handling units 108 are able to transport the primary containers within different planes. Resultantly, the container handling units 108 are able to cooperate in a variety of processing steps such as cleaning, rinsing, filling, capping, labeling, printing, coding, decorating, inspecting, collating, laning, grouping etc. requiring individual primary container transport and rotation, and in multiple degrees of freedom.
Further, because the container handling units 108 are highly flexible and adaptable according to different types of primary containers, different diameter, shape, size, height etc. of the primary containers, the processing system 100 do not require changing parts or components of the container handling units 108 depending on different types, shape, size, etc. of primary containers. Also, because changing parts of the container handling units 108 and other machine architectures is avoided in the present invention, it reduces bulkiness and complexity of the architectures, thus improving visibility and access of each component of the processing system 100 while simplifying machine construction.
The disclosure provides integration of multiple conveying functions into smaller, faster, highly flexible, adaptable, compact units, saving space while improving capacity, productivity, quality, and performance, while enabling real time individual product tracking capability and enhanced process control. The net result being that higher through put of a greater range of stylized products may be realized for a reduced size and number of machines.
The container handling units 108 include adaptable mover and tooling suitable for variety of ranges (families) of containers.
The container handling units 108 provide a variety of functions, such as translating and/or rotating the packaging containers or any combination thereof, which may include collecting, transferring, delivering, collating, laning, sorting, offsetting, grouping, pitching etc. The container handling units 108 also provide capability in performing manipulation operations on the packaging containers such as including buffering, aligning, singling, separating, grouping, pitching, synchronizing, sorting, merging, re-ordering, sequencing. Also, the container handling units 108 also provide performing processing operations on the packaging containers such as including gripping, manipulating, transferring, rotating, aligning, adjusting, and orientating.
Because the container handling units 108 are highly flexible, adaptable and dynamically programmable, they perform handling and processing operations by handling the packaging containers gently in a controlled acceleration, deceleration, while avoiding shocks or sudden impacts to the primary containers. Also, the container handling units 108 avoids shear forces on the packaging containers, and hence avoids rubbing, or chafing or destroying the surfaces of the packaging containers, thereby also protecting the labels on the packaging containers. Further, the container handling units 108 convey or transport the packaging containers smoothly without pressure, avoiding gearing/sprocket effects.
The position and inclination, and range of the transportation system and container handling units 108 and the mover and levitating tiles 106 may be automatically adjusted.
The processing system 100 can replace conventional processes such as including and not limited to single filer, scroll replacement, star wheel & guide replacement and pedestal elimination. The processing system 100 provides process to process transfer, through process handling, networking (dynamic switching, sorting, routing), buffering (1st in, 1st out).
Primarily, the processing system 100 is applicable to a wide range of applications. The container handling units 108 including the independent, motion controlled movers, levitating tiles and tooling may be auto adjusted or auto exchanged to quickly accommodate and handle a wide range of type, shape, size and height of primary product container, may also not be round nor of constant cross section). Further, the processing system 100 provides for automated changeover with execution occurring and being completed within seconds of changeover instruction via the HMI. The movers and or levitating tiles 106 adjust in position to the revised process, format and/or size of the primary container to be handled.
Furthermore, the processing system 100 may adapt new formats that may be accommodated via software programming which are faster to implement, adjust and update, plus may be implemented independent of the equipment OEM. Also, the processing system 100 has short lead times, because new introductions, changes and updates may be executed at short notice and within a short time frame.
Moreover, the processing system 100 may include reduced handovers, where the handovers of primary product containers from one device to another is reduced as the container handling via tooling on the movers and/or levitating tiles of the independent, motion controlled transportation systems transfer the product from the transportation system into the machine, through the machine and discharge onto the discharge transportation system, or hand off directly to another machine without giving up control to a general conveying device and having to regain pressure, pitch and timing control for infeed into the following process (eg. by further action of conveyor transfers, speed regulation, exposure to line pressures, recirculation, one or more timing scrolls and the series of star wheels and guides etc.
Advantageously, the processing system 100 provides for faster changeovers, higher productivity, as HMI directed automatic machine adjustments executed within seconds without personnel input nor exchange of format specific change parts. Also, the independent motion controlled movers or levitating tiles of the present smart processing system 100 are position settable.
Because the processing system 100 is not restricted to specific type and shape and size of packaging container, it may also provide non-circular primary handling. Programmable machine and tooling control enables ease of handling non-round primary containers and packaging, respectively (eg. obround, square, triangular, polygon, trapezium parallelogram, shapes), as well as shapes which are not of constant geometry.
The processing system 100 is faster, more compact, versatile, and can grip, lift/lower, rotate, orientate, invert, index, the containers, while executing in variable motion such as can pause, accelerate, decelerate, move in variable speed motion, also synchronize, and bypass, in addition can handle malfunction incidences (have redundancy). The processing system 100 assures line sanitization, in process tracking and tracing, can provide changeover on the fly and eliminate conveyors which block access about factory and which take up extensive amounts of space.
