Description

Technical Field

[0001] This invention relates to apparatus and methods for conveying objects, particularly containers. Background Technology

[0002] In container handling systems, containers can be processed and transported between individual sections of the equipment. Several technologies are known for transporting containers. Known transport technologies include, for example, long stator linear motor drives used to power the transported containers (shuttles).

[0003] For example, one possibility is an LLM conveyor star wheel with a single, circularly arranged long stator segment. For instance, an LLM conveyor star wheel could allow for a flexible container inlet located downstream of the machine.

[0004] Typically, in such shuttle systems, the object to be transported is guided on the outside of the motor segment or above or below a particular shuttle.

[0005] In this regard, see, for example, DE 10 2015 203 042 A1, DE 10 2017 01 331 A1 and DE 102019 110 056 A1.

[0006] A known drawback of the system is that, due to limitations such as the necessary shuttle width and motor system constraints, individual power units (shuttles) cannot move together completely or sufficiently closely (e.g., due to collision avoidance, excessive shuttle density, segmented loading), especially at higher speeds. This results in objects to be transported not entering and being taken over by the power units sequentially. The pitch circle diameter on which the power units move is also fixed and only applicable to subsequent machines to a limited extent. To account for these system limitations, for example, objects to be transported must be brought to a minimum distance before entering. In practice, this minimum distance is only achievable with considerable effort and associated drawbacks (e.g., using belt stations, chain overlap, etc.). Another significant drawback is that the minimum distance between objects, created in a defined manner, may be lost again during entry, such as in the event of a collision, contact with the guide, or displacement for other reasons. Therefore, process reliability is not optimal. Summary of the Invention

[0007] This invention aims to create an improved technique for transporting objects, preferably containers. Preferably, at least some of the aforementioned disadvantages should be overcome. Preferably, the technique allows object transport by taking over the control of objects from a continuous or at least nearly continuous flow of objects.

[0008] This objective is achieved by the features described in the independent claim. Advantageous developments are pointed out in the dependent claims and the specification.

[0009] One aspect relates to an apparatus for conveying an object, preferably a container, preferably a conveying star wheel. The apparatus has multiple (e.g., stationary) (e.g., electro) magnetic segments, preferably long stator segments. The multiple magnetic segments are arranged side-by-side on a closed, preferably (e.g., circular) annular or elliptical path curve. The apparatus has multiple power units, each having an (active or passive) object holder (e.g., a container holder) for holding the object and a (permanent) magnetic unit for magnetically interacting with the multiple magnetic segments to drive the respective power unit. Each magnetic unit is arranged externally relative to the closed path curve to move along a cyclic drive path. Each object holder is arranged to convey the held object on a conveying path located internally relative to the cyclic drive path.

[0010] In this device, the conveying path, which is usually located on the outside, is advantageously placed on the inside, i.e., inside the drive path. This allows the translation ratio of "object to desired power unit distance" to be positively influenced. For each object entry distance, the conveying path or object pitch circle placed inside can advantageously produce a corresponding power unit distance according to the translation ratio. However, this power unit distance is now advantageously larger than the actual object distance. This allows objects entering at significantly smaller pitches, including smaller objects / containers without gaps, to be received. Generally, this device allows object holders used for conveying objects to approach each other at pitches smaller than those traditionally allowed by magnetic units. Advantageously, this device can also significantly simplify the complexity of restart logic after collision situations (e.g., objects being pushed together), since the objects can only move slightly due to the lack of gaps. The internally arranged conveying path also advantageously helps to reduce the mass inertia acting on the power unit, which is also advantageous (e.g., low-segment loads during acceleration and deceleration).

[0011] Preferably, multiple magnetic segments are oriented outward relative to the closed path curve, and / or multiple magnetic units are oriented toward the closed path curve, and / or multiple magnetic segments and magnetic units are opposite to each other.

[0012] Preferably, the conveying path lies on the container pitch circle of the device. Preferably, the drive path can travel externally around the magnetic segment. Preferably, the drive path can enclose a closed path curve. For example, the conveying path and the drive path can be arranged coaxially with each other.

[0013] Preferably, the device does not have additional magnetic segments that are arranged externally relative to the magnetic segments and / or magnetic units, for example, arranged on an additional closed path curve that is located externally to or surrounds the closed path curve.

[0014] In one exemplary embodiment, multiple magnetic units can be driven independently of each other by multiple magnetic segments. Preferably, the multiple magnetic units and multiple magnetic segments together form a long stator linear motor drive system, a short stator linear motor drive system, or a planar motor drive system (e.g., having a closed drive surface). This advantageously allows the power unit to move independently.

[0015] In another exemplary embodiment, each object retainer is arranged internally relative to at least one of the following: a cyclic drive path, a closed path curve, a transport path, a plurality of magnetic units, and a plurality of magnetic segments. Alternatively or additionally, the object retainer for holding the object is oriented outward, and / or the object retainer is a (active or passive) container retainer (e.g., a container clamp or container receiver or container recess (container tray)), preferably used to hold one container at the container neck and / or at the container body. This advantageously allows for secure holding of objects and a simplified structure of the device, as it avoids conflicts in terms of installation and movement space, especially in the inlet and outlet areas.

[0016] In one implementation, at least one of the following conditions is met:

[0017] - The object holder is arranged at a different height from the magnetic unit and / or the plurality of magnetic segments, preferably above or below the magnetic unit and / or the plurality of magnetic segments; and

[0018] - The conveying path is arranged at a different height from the cyclic drive path, preferably above or below the cyclic drive path.

[0019] Advantageously, separating the conveyor height from the motor height allows for a particularly simple and efficient constructive implementation of the idea of ​​moving the conveyor path inward.

[0020] In another embodiment, each of the multiple power units has a (rigid) (bracket) connection structure that connects the object holder of the respective power unit and the magnetic unit of the respective power unit to each other.

[0021] In a variant of the implementation plan, at least one of the following conditions must be met:

[0022] - The connection structure is configured at least partially as a truss;

[0023] - The object holder and / or the magnetic unit are detachably attached to the connection structure for replacement;

[0024] - The object holder and / or magnetic unit are connected to the connection structure in a highly adjustable manner (e.g., vertically movable), preferably via a vertical guide and / or dovetail joint.

[0025] - The magnetic unit is arranged at one of the lower end and the upper end of the connecting structure, and the object holder is arranged at the other of the lower end and the upper end of the connecting structure;

[0026] - The connection structure is connected to a central guide post (e.g., located internally), preferably for guiding and optionally supporting the corresponding power unit on the central guide post.

[0027] This advantageously allows for a lightweight and simple structure for the power unit, which can be flexibly adapted to different requirements.

[0028] In another embodiment variation, the connecting structure also includes an elongated bracket, preferably a vertical bracket. Preferably, the elongated bracket is arranged internally relative to the transport path, and / or the elongated bracket supports the object holder. Optionally, the connecting structure may also have a cantilever (e.g., a truss) that connects the elongated bracket and the magnetic unit, and optionally supports the magnetic unit on the elongated bracket. Advantageously, the connecting structure can therefore be particularly lightweight and simple.

[0029] In one exemplary embodiment, the device also has a preferably fixed (positioned) support plate for supporting the object to be held by the object holder at the base. Preferably, the support plate can be arranged between the object holder and the magnetic segment. Preferably, the support plate can have a curved path following the transport path. Advantageously, this can significantly simplify the structure of the object holder and the power unit, as they preferably do not have to bear the weight of the object during transport.

[0030] In another exemplary embodiment, the device further includes lateral guiding elements, preferably lateral railings or sidewalls, for laterally guiding the object held by the object holder along the transport path. Preferably, the lateral guiding elements may be arranged externally relative to the object holder and / or the transport path. Preferably, the lateral guiding elements may have a curved path that follows the transport path. Advantageously, this can significantly simplify the structure of the object holders, as they preferably only need to push the object during transport.

[0031] In one embodiment, the device also includes an inlet conveyor arranged to transfer objects to multiple power units. Preferably, the inlet conveyor may have a frame with slits. For example, the slits may span a portion of a magnetic segment (e.g., in a bridge-like manner). Alternatively or additionally, portions of the power units (e.g., portions of connecting structures, such as cantilever and / or magnetic units and / or their housings) may move through the slits during operation of the device. This advantageously allows the inlet conveyor to travel in a structurally simple manner along the currently internal transport path.

[0032] In another embodiment, the magnetic unit (e.g., partially or completely) is housed within the housing of the respective power unit. The dimensions of the object holder and the housing are configured such that when adjacent power units move together, the object holder and / or the object contact each other, while the housing remains spaced apart. Advantageously, this allows for receiving objects from a continuous inlet flow.

[0033] In one embodiment variation, multiple power units are guided and optionally supported (e.g., via a connecting structure) without rollers and / or on a central guide post of the device. Alternatively, the multiple power units may each have at least one guide roller that guides along a circulating guide track and optionally supports the respective power unit. This advantageously allows for the safe and reliable guidance of the power units, and therefore the object holder and magnetic unit.

[0034] In another embodiment variation, the device further includes a locking device arranged in the inlet area of ​​the device and actuable (e.g., by means of the device's processing unit) for selectively blocking (and obstructing) or releasing the inlet flow of objects. Preferably, the locking device may have movable (e.g., extendable and retractable or pivotable) locking elements (e.g., locking fingers, locking pins, or locking barriers) for blocking objects in the inlet flow. The locking device can advantageously prevent the conveyor path from becoming clogged with objects in the event of a malfunction. Instead, the locking device can block objects on the inlet conveyor until the malfunction is rectified. The blocked objects can then be preferably received and transported sequentially and without gaps by a power unit in the inlet area.

[0035] In one exemplary embodiment, the device further includes a processing unit configured to operate a plurality of magnetic segments and / or magnetic units, such that...

[0036] - The object holder of the plurality of power units is capable of taking over a continuous or nearly continuous flow of objects into the inlet (e.g., in the inlet region of the device), and optionally,

[0037] - The power unit increases or decreases the distance between adjacent conveyed objects from the inlet area to the outlet area of ​​the equipment, preferably increasing or decreasing the distance to a predefined object (e.g., equal to the predefined pitch of the conveying element of the outlet conveyor of the equipment).

[0038] This also advantageously allows the control system to implement object takeover by the power unit from a continuous inlet flow.

[0039] Preferably, the term "processing device" can refer to an electronic system (e.g., configured to drive circuitry or have a microprocessor and data memory) that, depending on its configuration, can perform open-loop control tasks and / or closed-loop control tasks and / or processing tasks. Although the term "control" is used herein, it can also include or be understood as "closed-loop control" or "control with feedback" and / or appropriate "processing". The processing device can be, for example, a centralized processing device or have multiple distributed or decentralized processing units.

[0040] On the other hand, it relates to a container handling system (e.g., for temperature control, production, cleaning, coating, testing, rinsing, filling, sealing, pasteurizing, decorating, labeling, printing, marking, laser marking, and / or packaging of containers for liquid or paste-like media (preferably beverages, liquid foods, or products from the pharmaceutical or healthcare industries)). The container handling system may have the equipment disclosed herein. The container handling system may, for example, be a beverage filling facility.

[0041] For example, the container can be configured as a bottle, jar, tube, cardboard box, vial, tube, etc.

[0042] On the other hand, a method for conveying objects, preferably containers, and / or conveying objects via devices as disclosed herein is provided. This method involves conveying objects along a conveying path via object holders with multiple power units, wherein:

[0043] -The conveying path is arranged internally relative to the cyclic drive path;

[0044] - Multiple power unit (e.g., permanent) magnetic units move along the cyclic drive path, driven by magnetic interaction with multiple (e.g., fixed) (e.g., electric or permanent) magnetic segments (e.g., long stator segments) arranged side-by-side on a closed (e.g., preferably (e.g., circular) annular or elliptical) path curve; and

[0045] - The cyclic drive path is arranged outside (or surrounds) the closed path curve relative to the closed path curve.

[0046] Advantageously, this method can achieve the same advantages as those already described with reference to the device. This also applies to the preferred examples of the method explained below.

[0047] In one exemplary implementation, the method further includes at least one of the following:

[0048] - The object holder of the plurality of power units takes over the object from a continuous or nearly continuous flow of object inlets (e.g., a portion of the total flow);

[0049] - The object is transferred to the object exit flow by the object holder of the plurality of power units, wherein adjacent objects are positioned at a predefined object distance from each other;

[0050] - During the conveying process, the object is pushed over a preferably curved support plate and / or along a preferably curved lateral guide element by the object holder of the plurality of power units;

[0051] - Preferably, the object inlet flow to the plurality of power units is blocked by the locking device in at least one of the following situations: error during transport, takeover, or transfer; failure of one of the plurality of power units; failure of one of the plurality of magnetic segments; failure of the device for handling and / or transporting the object, the device being arranged downstream of the plurality of power units; detected damage to the object; and operator input.

[0052] It is also possible that the object is taken over from the object inlet stream by the object holder, which has objects, such as containers, entering sequentially at arbitrary intervals.

[0053] The preferred embodiments and features described above can be combined with each other as desired. In particular, all features described with respect to the device can also be applied and claimed in conjunction with the method, and vice versa. Attached Figure Description

Detailed Implementation

[0063] Figures 1 to 6 A device 10 (or a portion thereof) for conveying an object (article) 12 is shown. The object 12 is preferably implemented as a single container or a bundle of containers. Particularly preferably, the device 10 is included in a container handling system.

[0064] The following is for reference. Figures 1 to 6 The device 10 will be described in more detail. Figure 1 A schematic diagram of device 10 is shown. Conversely, Figures 2 to 6 A perspective structural view of a preferred exemplary embodiment of device 10 is shown.

[0065] Device 10 includes, for example, an intermediate conveyor 30 having multiple magnetic segments 36 and multiple power units 38. Optionally, device 10 may also include, for example, an inlet conveyor 14, a sensor device 24, an outlet conveyor 26, a locking device 58, and / or a processing device 60 (see...). Figure 1 ).

[0066] The entrance conveyor 14 can transport object 12 to conveyor 30.

[0067] The entrance conveyor 14 can preferably transport objects 12 in an upright position and / or support them at a base. Preferably, the entrance conveyor 14 can be a linear conveyor. Preferably, the entrance conveyor 14 can transport rows of objects 12 one after another. The entrance conveyor 14 is preferably single-channel.

[0068] Specifically, the inlet conveyor 14 can transport the inlet flow of objects 12 to the (object) inlet region 32 of the conveyor 30. In the object inlet flow, the objects 12 can be positioned relative to each other with virtually no gap or almost no gap. Preferably, adjacent objects 12 can be in contact with each other.

[0069] For example, the second inlet conveyor 14 may have a circulating conveyor element 16. The circulating conveyor element 16 may be, for example, a belt, plate, pad, or chain conveyor element.

[0070] The circulating conveyor element 16 can be guided and driven, for example, in the frame 18 of the inlet conveyor 14 (see...). Figure 2 and Figure 3 The frame 18 can be open or enclosed. For example, the frame 18 can be enclosed in a closed housing, preferably enclosed in a conveyor element box (e.g., a chain box).

[0071] For example, the drive wheel and multiple deflector wheels 20 can be rotatably mounted in / on the frame 18 (see [link]). Figure 2 The drive wheel can drive and guide the circulating conveyor element 16 to transport the object 12. The deflection wheel 20 can guide the circulating conveyor element 16, for example, in the corner area of ​​the frame 18.

[0072] Preferably, the frame 18 of the inlet conveyor 14 may have a cutout 22 for accommodating a portion of the conveyor 30 (see [link]). Figure 2 and Figure 3 Preferably, the cutout 22 can be arranged in the entrance area 32 of the conveyor 30.

[0073] The cut 22 may span a portion of the conveyor 30. For example, the cut 22 may span a portion of the conveyor 30 in a bridge-like manner. For example, the cut 22 may span a portion of the magnetic segment 36 of the conveyor 30. The cut 22 may, for example, be substantially rectangular.

[0074] Preferably, the cut 22 can create a movement space for the partial passage of the power unit 38. For example, during operation of the device 10, the connection structures 46 of the power unit 38 (e.g., their cantilever 50; see...) Figures 4 to 6 It can move through the cut 22 or the space created by the cut 22.

[0075] For example, at least one deflector 20 of the inlet conveyor 14 may be arranged to guide the circulating conveyor element 16 along or after the cut 22 (see Figure 2 ).

[0076] The cut 22 can preferably be arranged on the return stroke or the lower stroke of the inlet conveyor 14. Particularly preferably, the cut 22 can be arranged on the lower return stroke of the inlet conveyor 14.

[0077] Sensor device 24 is only shown as an example. Figure 1 As shown in the diagram. For example, sensor device 24 may have one sensor or multiple sensors spaced apart from each other. Sensor device 24 may preferably be arranged to the side or directly above the inlet conveyor 14.

[0078] Sensor device 24 can detect objects 12 in the object inlet flow. Preferably, sensor device 24 can detect when a particular object 12 passes a specific position along the inlet conveyor 14. However, sensor device 24 can also, for example, directly detect the current position of the object 12 or directly detect the spatial and / or temporal distance between the objects 12.

[0079] The signal output of the sensor device 24 regarding the detected object 12 can be received by the processing device 60. Accordingly, the processing device 60 can, for example, control the movement of the power unit 38 to receive the object 12.

[0080] Export conveyor 26 is shown as an example only. Figure 1 As shown in the diagram. The exit conveyor 26 can transport the object 12 away from the conveyor 30. Preferably, the exit conveyor 26 can take over the object 12 in the (object) exit area 34 of the conveyor 30 and transport it away.

[0081] The exit conveyor 26 may, for example, have multiple conveying elements 28. The object 12 may be conveyed by the conveying elements 28. Specifically, the conveying elements 28 may convey the exit flow of the object 12 out of the exit area 34 of the conveyor 30 one after another.

[0082] The conveying element 28 may be configured as an object holder, preferably a container holder. Preferably, each of the conveying elements 28 may have a support plate on which the object 12 can stand upright. Alternatively or additionally, the conveying element 28 may have, for example, a clamp or gripper that can hold the object 12 by means of its side surface, neck, and / or neck ring.

[0083] The conveying element 28 is movable to convey the object 12. The outlet conveyor 26 is particularly preferably configured as a rotary conveyor. The conveying element 28 can move along the circular path of the rotary conveyor to convey the object 12.

[0084] Preferably, the exit conveyor 26 is itself part of an object handling device for handling the object 12. For example, the object handling device may fill, enclose, or decorate (e.g., mark) the object 12, which is preferably configured as a container, while conveying the object 12 via the conveying element 28.

[0085] For example, the object handling device can be configured as a filling device for filling object 12. The filling device may include an outlet conveyor 26. The filling device may preferably fill the object (e.g., container 12) with a liquid or paste-like medium. The filling device is preferably configured as a rotary filling device. The filling device may have multiple filling valves for filling multiple objects 12 simultaneously or in a time-overlapping manner. For example, the filling valves may be arranged around the periphery of the filler turntable of the rotary filling device.

[0086] Alternatively, the object handling device may be, for example, a sealing device for sealing object 12. The sealing device may include an outlet conveyor 26. The sealing device may seal object (e.g., container) 12, for example, with a lid, cork, crown cap, or screw cap. The sealing device may preferably be configured as a rotary sealing device. The sealing device may have multiple sealing stations for sealing multiple objects 12 simultaneously or in a time-overlapping manner. For example, the sealing stations may be arranged around the periphery of the sealing turntable of the rotary sealing device.

[0087] Alternatively, the object handling device may be, for example, a marking device for marking the object 12. The marking device may include an exit conveyor 26. The marking device may mark the object (e.g., container) 12, for example, with self-adhesive labels, cold glue labels, or roll labels. The marking device may preferably be configured as a rotary marking device. In the marking device, the conveying element 28 may be configured, for example, as a rotatable object receiver (e.g., object turntable) for the object 12, which is arranged around the periphery of the marking turntable of the rotary marking device. The conveying element 28 having the object 12 housed therein or on it can move through at least one marking unit of the marking device. At least one marking unit may be arranged, for example, on the periphery of the rotary marking device.

[0088] Preferably, the conveying elements 28 that are adjacent to each other are arranged with a predetermined fixed pitch.

[0089] Conveyor 30 can transport object 12 from its inlet area 32 to its outlet area 34. In the inlet area 32, conveyor 30 can take over object 12 from inlet conveyor 14. In the outlet area 34, conveyor 30 can transfer object 12 to outlet conveyor 26. Preferably, conveyor 30 can be configured as a conveyor star wheel that can transport object 12 on a circular path.

[0090] The conveyor 30 has multiple magnetic segments 36 and multiple power units 38. Optionally, the conveyor 30 may also have, for example, a support plate 54 and / or lateral guide elements 56 (see...). Figure 2 and Figure 3 ).

[0091] Magnetic segments 36 are arranged side-by-side on a closed (path) curve. The path curve or the arrangement of the magnetic segments 36 can be, for example, a ring shape, such as... Figure 1 As illustrated in the example. Alternatively, for example, the path curve or arrangement of the magnetic segment 36 may be elliptical.

[0092] Preferably, all magnetic segments 36 are arranged at the same height. The path curve can preferably be located in a horizontal plane.

[0093] For example, each of the magnetic segments 36 has one or more magnets, such as permanent magnets or electromagnets. Preferably, the magnetic segments 36 are stationary or fixed in place.

[0094] Preferably, the magnetic segment 36 or its magnet is oriented outward relative to the closed path curve.

[0095] Power unit 38 is used to transport object 12. Power unit 38 may also be referred to as a mover or shuttle. Preferably, object 12 can be transported individually by one of the power units 38. Alternatively, for example, each power unit 38 can transport multiple objects 12, or multiple power units 38 can transport one object 12 together, for example, by maintaining it between multiple power units 38.

[0096] Each power unit 38 has a magnetic unit 40 and an object holder 44 for holding (at least) one object 12 during transport. Optionally, each power unit 38 may have a connection structure 46.

[0097] The magnetic unit 40 is used to magnetically interact with multiple magnetic segments 36 to drive the corresponding power unit 38.

[0098] For example, each magnetic unit 40 has one or more magnets, such as permanent magnets or electromagnets. Preferably, the magnetic unit 40 or its magnets may be partially or completely housed in the housing 42 of the corresponding power unit 38.

[0099] The magnetic unit 40 is positioned outward relative to the magnetic segment 36 or the closed path curve on which the magnetic segment 36 is arranged. The magnetic unit 40 is arranged to move on a cyclic drive path A. Therefore, the drive path A is positioned outward relative to the closed path curve on which the magnetic segment 36 is arranged, or outward relative to the magnetic segment 36.

[0100] For example, the magnetic unit 40 or its magnet can be oriented toward a closed path curve on which the magnetic segments 36 are arranged. The magnetic segments 36 and the magnetic unit 40 can be directly opposite each other.

[0101] Preferably, the magnetic units 40 can be driven independently of each other or individually by the magnetic segments 36. Therefore, the power units 38 can move independently of each other and be magnetically driven individually.

[0102] For example, the power unit 38 can be driven by a long stator linear motor drive system, a short stator linear motor drive system, or a planar motor drive system of the device 10 or the conveyor 30. That is, the magnetic unit 40 and the magnetic segment 36 can together form a long stator linear motor drive system, a short stator linear motor drive system, or a planar motor drive system.

[0103] Particularly preferably, the conveyor 30 is configured as a long stator linear motor conveyor. Magnetic segments 36 can be configured as long stator segments. The long stator segments can together form a preferred (e.g., circular) annular or elliptical long stator. Each long stator segment can have an electromagnet for inducing movement or driving the magnetic unit 40 equipped with permanent magnets.

[0104] However, the conveyor 30 can also be, for example, a short stator linear drive conveyor or a planar linear drive conveyor.

[0105] In a short stator linear motor drive, magnetic segments 36 and magnetic units 40 can together form a short stator linear motor drive system. Magnetic unit 40 may have an electromagnet for forming the short stator, which can magnetically interact with the fixed permanent magnets of magnetic segments 36 to drive the corresponding power unit 38.

[0106] A planar motor conveyor can be made of magnetic segments 36 ( Figure 1 The power unit 38, made of a stator (not shown), moves in at least two degrees of freedom (circumferential and z-direction) on a preferably closed drive surface. Magnetic segments 36 and magnetic units 40 can together form a planar motor drive system. The stator made of magnetic segments 36 can also be referred to as a platform or base element. The lifting and / or tilting movements of the power unit 38 relative to the stator / base element can also be controlled by magnetic interaction. The base element can preferably be divided into blocks. The stator or magnetic segments 36 can be formed, for example, by movable (e.g., rotatable) permanent magnets or by fixed electromagnets. The magnetic units 40 preferably have permanent magnets.

[0107] The object holder 44 can be active or passive.

[0108] Preferably, the object holder 44 has at least one object recess (object receiver or object tray) that can contact the object 12 by contacting its neck and / or side surfaces (body). The object 12 can be at least partially received in the object recess (preferably a container recess). For example, when the corresponding power unit 38 is moved, the object 12 can be pushed and thus conveyed by the object recess. Alternatively, the object holder 44 can have, for example, a support plate on which the object 12 can stand upright. Alternatively or additionally, the object holder 44 can have a clamp or gripper that can hold the object 12 by its side surfaces, neck, and / or neck ring.

[0109] The object holders 44 are arranged such that they transport the held object 12 on the transport path T located inside the cyclic drive path A.

[0110] For example, the object holder 44 may be arranged internally relative to the cyclic drive path A, the closed path curve, the transport path T, the magnetic unit 40 and / or the magnetic segment 36.

[0111] Preferably, the object holder 44 can be oriented outward to hold the object 12.

[0112] Preferably, the object holder 44 is arranged at a different height than the magnetic unit 40 and the magnetic segment 36. For example, the object holder 44 can be arranged above or below the magnetic unit 40 and the magnetic segment 36. Therefore, the transport path T can be arranged at a different height than the cyclic drive path A, for example, above or below the cyclic drive path. Figures 2 to 6 In the exemplary embodiment shown, the object holder 44 is arranged, for example, above the magnetic unit 40 and the magnetic segment 36, so that the transport path T is also arranged above the drive path A.

[0113] The connection structure 46 can connect the object holder 44 of the corresponding power unit 38 and the magnetic unit 40 of the corresponding power unit 38 to each other. The connection structure 46 is preferably rigid. Preferably, the connection structure 46 can transmit the motion of the magnetic unit 40 to the object holder 44.

[0114] For example, the upper end of the connecting structure 46 can be directly connected to the object holder 44, and the lower end of the connecting structure 46 can be directly connected to the magnetic unit 40 and / or the housing 42, and vice versa.

[0115] Preferably, for replacement, the object holder 44 can be detachably attached to the connecting structure 46, for example via screws, plugs and / or clamps, for example at the upper end region of the connecting structure 46.

[0116] Particularly preferably, the object retainer 44 is connected to the connecting structure 46 in a height-adjustable (e.g., vertically movable) manner. For example, the connecting structure 46, particularly its upper portion, can be connected to the object retainer 44 via a vertical guide and / or via a dovetail joint. Preferably, the object retainer 44 can be secured to the connecting structure 46 at different height positions, preferably steplessly.

[0117] Preferably, for replacement, the housing 42 and / or the magnetic unit 40 can be detachably attached to the connection structure 46, for example, via screws, plugs and / or clamps, such as to the lower end region of the connection structure 46.

[0118] Preferably, the magnetic unit 40 is connected to the connecting structure 46 in a height-adjustable (e.g., vertically movable) manner, for example, via the housing 42. For example, the connecting structure 46 (e.g., the lower end region of the connecting structure 46) can be connected to the magnetic unit 40 and / or the housing 42 via a vertical guide and / or via a dovetail joint. Preferably, the magnetic unit 40 can be securely fastened to the connecting structure 46 at different height positions, preferably steplessly.

[0119] For example, the connecting structure 46 may have an elongated bracket 48 and a cantilever 50 (see, for example, see...). Figures 3 to 6 ).

[0120] The elongated bracket 48 can be, for example, rod-shaped, column-shaped, beam-shaped, or strip-shaped. Preferably, the elongated bracket 48 is a vertical bracket. Preferably, the bracket 48 can be arranged internally relative to the object holder 44 or the transport path T. Preferably, the bracket 48 can have an upper end region to which the object holder 44 is detachably attached, for example via a vertical guide and / or a dovetail joint, or simply screwed together.

[0121] The cantilever 50 may preferably be arranged directly below the object holder 44 of the corresponding power unit 38. For example, the cantilever 50 may extend from the bracket 48, for example, radially outward and / or toward the housing 42 and / or magnetic unit 40 of the corresponding power unit 38.

[0122] The cantilever 50 may connect the bracket 48 and the magnetic unit 40, for example, via the housing 42. Preferably, the housing 42 and / or the magnetic unit 40 may be arranged at one end of the cantilever 50. Preferably, the housing 42 and / or the magnetic unit 40 may be detachably attached to the end of the cantilever, for example, via a vertical guide and / or a dovetail joint, or threaded or welded together.

[0123] Preferably, the cantilever 50 can support the housing 42 and / or the magnetic unit 40 on the bracket 48. At least, the cantilever 50 can transmit the movement of the magnetic unit 40 to the bracket 48, and thus to the object holder 44.

[0124] Preferably, the connection structure 46 can be configured at least partially as a truss. For example, the cantilever 50 can be implemented as a truss structure.

[0125] Preferably, the connecting structure 46 is arranged above the magnetic segment 36. For example, the bracket 48 and / or the cantilever 50 may be arranged above the magnetic segment 36, preferably directly above the magnetic segment 36.

[0126] The power unit 38 can be guided and optionally supported on the central guide post 52 (see, for example, see...). Figure 2 and Figure 3 The guide post 52 may be located internally, for example, centered relative to the transport path T and / or drive path A.

[0127] For example, the power unit 38 can be guided and supported on the guide post 52 via the connecting structure 46. Preferably, the connecting structure 46 can be rotatably connected to the guide post 52, for example, via a bracket 48.

[0128] The power unit 38 guided on the central guide post 52 preferably does not have rollers. Alternatively, for example, multiple power units 38 may each have at least one guide roller that guides along a circulating guide track and optionally supports (not shown) the respective power unit 38. At least one guide roller may be arranged, for example, on the connecting structure 46 and / or the housing 42 and / or the object holder 44.

[0129] Support plate 54 can be used to support object 12 held by object holder 44 at the base (see... Figure 2 and Figure 3 For example, during transport, object 12 can be pushed above curved support plate 54 by object holder 44 of power unit 38.

[0130] Preferably, the support plate 54 may have a curved path that follows the conveying path T. Preferably, the support plate 54 may be disposed directly below the conveying path T. For example, the support plate 54 may be disposed between the object holder 44 and the magnetic segment 36.

[0131] Lateral guide element 56 can be used to laterally guide object 12 held by object holder 44 (see) on the transport path T. Figure 2 and Figure 3 For example, during transport, object 12 can be pushed along the lateral guide element 56 by object holder 44 of power unit 38.

[0132] For example, the lateral guide element 56 may be a lateral railing or a lateral wall. Preferably, the lateral guide element 56 may be arranged externally relative to the object holder 44 and / or the conveying path T. For example, the lateral guide element 56 may have a curved path along the conveying path T.

[0133] Locking device 58 is only shown by way of example. Figure 1 As shown in the diagram. The locking device 58 can be selectively actuated to block or release the inlet flow of object 12. A released inlet flow can enter the conveyor 30, allowing object 12 to be taken over by the power unit 38. The inlet flow can be blocked by the locking device 58 before entering the conveyor 30, preventing any object 12 from being taken over by the power unit 38. Then, an alternative inlet flow of object 12 can be used as a backup. The locking device 58 can be operated, for example, by the processing device 60.

[0134] Preferably, the locking device 58 may be arranged in the entrance region 32 and / or at the end region of the entrance conveyor 14. For example, the locking device 58 may be arranged such that when the object 12 is positioned on / at the entrance conveyor 14 or conveyed by the entrance conveyor, the locking device 58 can block the object. Alternative or additional barriers may also be arranged further upstream (e.g., to achieve at least part of the function). This function may also be achieved through lateral overlap.

[0135] For example, when an error during transport, a failure of one of the multiple power units 38, a failure of one of the multiple magnetic segments 36, damage to the object 12, corresponding operator input, and / or a failure of a device (e.g., a filling device, a sealing device, or a marking device) arranged downstream of the conveyor 30 for handling and / or transporting the object 12 is identified or detected, the locking device 58 can be actuated to block the inlet flow.

[0136] The locking device 58 may, for example, have a movable (mechanical) locking element for blocking the object 12. The locking element may, for example, be a locking finger, a locking pin, or a locking barrier.

[0137] The locking element can, for example, move between a blocking position and a releasing position. In the blocking position, object 12 can be blocked. In the blocking position, the locking element can act as a stop for the (forward) object 12. In the releasing position, object 12 can be released for transport and entry into conveyor 30.

[0138] Preferably, the locking element can be moved by an actuator of the locking device 58. The actuator can be, for example, a mechanical, pneumatic, hydraulic, electrical, or electromagnetic actuator. The mobility of the locking element can, for example, include the ability to extend and retract and / or pivot. Damping can also be integrated into the locking element. The actuator can, for example, be operated by a processing device 60.

[0139] Processing device 60 in Figure 1 The diagram is shown only by way of example. The processing device 60 can be configured to operate the device 10.

[0140] For example, the processing device 60 can be signal connected to the inlet conveyor 14, sensor device 24, outlet conveyor 26, conveyor 30, magnetic segment 36, magnetic unit 40 and / or locking device 58.

[0141] Preferably, the processing device 60 is operable with magnetic segments 36 and / or magnetic units 40 such that the object holders 44 of the plurality of power units 38 can take over the inlet flow of continuous or nearly continuous objects in the inlet region 32. Optionally, the power units 38 can increase the distance between adjacent conveyed objects 12 from the inlet region 32 to the outlet region 34, preferably to a predefined object distance corresponding to the pitch of the outlet conveyor 26. The power units 38 can then transfer the objects 12 to the conveying elements 28 of the outlet conveyor 26 at their pitch.

[0142] Figure 7 This schematically illustrates how the arrangement of the internal transport path T relative to the drive path A can have an advantageous effect.

[0143] Adjacent magnetic units 40 (and thus associated power units 38) can be moved so close together that the object holder 44 and / or the object 12 held by the object holder 44 come into contact with each other. In this state, preferably the housing 42 containing the magnetic units 40 is not yet in contact.

[0144] The close proximity of the object holder 44 and the object 12 in the region ultimately allows the object holder 44 to take over the object 12 from the substantially or nearly continuous inlet flow of the inlet conveyor 14.

[0145] Accordingly, the dimensions of the object holder 44 and the housing 42 in which the magnetic unit 40 is housed can be set such that when they move together, the object holder 44 and / or the object 12 contact each other while the housing 42 remains spaced apart from each other.
