Description

Technical Field

[0001] The present invention relates to an apparatus and a method for transporting an object, preferably a container.

Background Art

[0002] In a container processing system, containers can be processed and transported between individual parts of the system. Various techniques for transporting containers are known. Known transport techniques include, for example, a long stator linear motor drive for driving a moving device (shuttle) that transports a container.

[0003] For example, an LLM transport star wheel having individual circularly arranged long stator segments can be considered. For example, an LLM transport star wheel can enable a flexible container inlet with a downstream disposed machine.

[0004] Conventionally, an object transported in such a shuttle system is guided outside the motor segment or above or below a specific shuttle.

[0005] In this context, reference is made, for example, to German Patent Application Publication No. 102015203042, German Patent Application Publication No. 10201701331, and German Patent Application Publication No. 102019110056.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The known drawbacks of the system include, for example, the fact that individual moving devices (shuttle) cannot move together completely or sufficiently close, especially at high speeds, due to the required shuttle width and limitations of the motor system (e.g., due to collision avoidance, excessive shuttle density, segment load). As a result, the objects being transported cannot enter continuously and cannot be taken over by the moving devices. The diameter of the pitch circle on which the moving devices travel is also fixed and can only be adapted to subsequent machines to a limited extent. To account for these system limitations, the objects being transported must be moved to a minimum distance before entry. In practice, achieving the required minimum distance is only possible with considerable effort and associated drawbacks (e.g., using belt stations, chain overlaps, etc.). Another significant drawback is that the minimum distance generated between objects in a specified manner may be lost again during entry, for example, in collision situations, contact with guides, or in objects that have shifted for other reasons. Thus, the reliability of the process is not optimal.

[0007] The present invention aims to produce an improved technique for transporting objects, preferably containers. Preferably, at least some of the aforementioned drawbacks should be overcome. Preferably, the technique enables the transport of objects by taking over objects from a continuous or at least substantially continuous flow of objects. [Means for solving the problem]

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

[0009] One embodiment relates to a device for transporting objects, preferably containers, preferably a transport star wheel. The device has a plurality of (e.g., electromagnetic) magnetic segments, preferably long stator segments. The plurality of magnetic segments are arranged in a line on a closed, preferably (e.g., circular) ring-shaped or elliptical path curve. The device has a plurality of moving devices, each having an (e.g., active or passive) object holder (e.g., container holder) for holding objects and a (e.g., permanent) magnetic unit for magnetic interaction with the plurality of magnetic segments to drive the respective moving device. The magnetic units are each positioned outward relative to the closed path curve in order to move along a circulating drive path. The object holders are each positioned to transport the held objects on a transport path located inward relative to the circulating drive path.

[0010] In this device, the transport path for objects, which is normally located on the outside, is advantageously positioned on the inside, i.e., inside the drive path. This allows for a positive influence, so to speak, on the translation ratio, "the distance from the object to the required moving device." For each incoming object distance, the internally positioned transport path or object pitch circle can advantageously result in a corresponding moving device distance according to the translation ratio. However, it is advantageous here that this moving device distance is greater than the actual object distance. This makes it possible to receive objects entering at significantly small pitches, including small objects / containers, without gaps. Generally speaking, the device can allow object holders used to transport objects to approach each other at a smaller pitch than conventionally possible with magnetic unit pitches. Advantageously, the device can also greatly simplify the complexity of the restart logic after collision situations (e.g., objects being pushed together) because the objects can only shift slightly due to the lack of gaps. The internally positioned transport path also has the advantage of reducing the mass inertia acting on the moving device, which is also beneficial (e.g., lower segment load during acceleration and deceleration).

[0011] Preferably, the magnetic force segments are oriented outward with respect to the closed path curve, and / or the magnetic force units are oriented toward the closed path curve, and / or the magnetic force segments and magnetic force units face each other.

[0012] Preferably, the transport path lies on the container pitch circle of the apparatus. Preferably, the drive path can extend around the outer magnetic segment. Preferably, the drive path can enclose a closed path curve. For example, the transport path and the drive path may be arranged coaxially with each other.

[0013] Preferably, the apparatus does not include additional magnetic segments located outside of the magnetic segment and / or magnetic unit, for example, located outside of a closed path curve or on a further closed path curve enclosing a closed path curve.

[0014] In an exemplary embodiment, multiple magnetic force units are driveable independently of each other by multiple magnetic force segments. Preferably, the multiple magnetic force units and multiple magnetic force 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 moving devices to be moved individually.

[0015] In another exemplary embodiment, the object holder is positioned inward relative to at least one of the circulating drive path, closed path curve, transport path, multiple magnetic force units, and multiple magnetic force segments. Alternatively or additionally, the object holder for holding the object is oriented outward, and / or the object holder is preferably an (e.g., active or passive) container holder (e.g., container clamp or container receptacle or container pocket (container tray)) for holding one container each at the container neck and / or container body of the container. This is advantageous as it avoids collisions with respect to the installation and movement spaces, particularly in the inlet and outlet regions, thus enabling secure holding of the object and a simplified structure of the device.

[0016] In one embodiment, the following conditions apply, namely, - The object holder is positioned at a different height from the magnetic unit and / or multiple magnetic segments, preferably above or below, and - The transport path is located at a different height from the circulating drive path, preferably above or below. It satisfies at least one of the following conditions.

[0017] Advantageously, the approach of separating the transport height from the motor height can enable a particularly simple and efficient structural implementation of the idea of ​​moving the transport path inward.

[0018] In another embodiment, each of the multiple moving devices has a (e.g., rigid) (e.g., carrier) connection structure that connects the object holder of each moving device to the magnetic unit of each moving device.

[0019] In a modified version of one embodiment, at least one of the following conditions is met. - The connecting structure is configured as a truss, at least partially. - The object holder and / or magnetic unit are detachably mounted to the connecting structure for replacement. - The object holder and / or magnetic unit is preferably connected to the connecting structure in a height-adjustable (e.g., vertically movable) manner via vertical guides and / or dovetail joints. - The magnetic force unit is located at one of the lower and upper ends of the connecting structure, and the object holder is located at the other of the lower and upper ends of the connecting structure. - The connection structure is preferably connected to the central guide column (e.g., located on the inside) to guide and optionally support each moving device on the central guide column.

[0020] This has the advantage of enabling lightweight and simple structures for mobile devices that can be flexibly adapted to different requirements.

[0021] In a variation of another embodiment, the connecting structure further comprises an elongated carrier, preferably a vertical carrier. Preferably, the elongated carrier is positioned inward relative to the transport path and / or supports the object holder. Optionally, the connecting structure may further comprise a cantilever (e.g., a truss) that connects, for example, the elongated carrier to a magnetic unit and optionally supports the magnetic unit on the elongated carrier. Advantageously, the connecting structure can thus be particularly lightweight and simple.

[0022] In one exemplary embodiment, the apparatus further includes a preferably stationary (fixed in place) support plate for supporting the object held by the object holder from below. Preferably, the support plate may be positioned between the object holder and the magnetic segment. Preferably, the support plate may have a curved course that follows the transport path. Advantageously, this can significantly simplify the structure of the object holder and the transport device because they preferably do not need to support the weight of the object during transport.

[0023] In a further exemplary embodiment, the device further has lateral guide elements, preferably lateral rails or side walls, for guiding the object held by the object holder laterally on the transport path. Preferably, the lateral guide elements can be arranged outside the object holder and / or the transport path. Preferably, the lateral guide elements can have a curved course following the transport path. Advantageously, this can significantly simplify the structure of the object holder. This is because the object holder preferably only needs to push the object during transport.

[0024] In one embodiment, the device further has an inlet conveyor arranged to transfer the object to a plurality of moving devices. Preferably, the inlet conveyor can have a frame with a notch. For example, the notch can span (e.g., in a bridge-like manner) part of the magnetic segments. Alternatively or additionally, part of the moving device (e.g., part of the connection structure, e.g., a cantilever, and / or the magnetic unit and / or their housings) can be moved through the notch during operation of the device. Thereby, advantageously, in a structurally simple way, the inlet conveyor can now extend all the way to the now-inner located transport path.

[0025] In another embodiment, the magnetic units are (e.g., partially or completely) housed within the housing of each moving device. The object holder and the housing are dimensioned such that when adjacent moving devices move together, the object holder and / or the objects contact each other while the housings remain spaced apart. Advantageously, this enables the object to be taken over from the continuous inlet flow.

[0026] In a modification of an embodiment, the plurality of moving devices are guided without rollers and / or on the central guide column of the device and optionally supported (e.g., via a connection structure). Alternatively, the plurality of moving devices can each have, for example, at least one guide roller, and the guide rollers guide and optionally support each moving device along a circulating guide track. Thereby, advantageously, a safe and reliable guide of the moving devices, and thus of the object holder and the magnetic unit, becomes possible.

[0027] In a modification of another embodiment, the device further has a locking device arranged in the inlet region of the device and operable (e.g., by a processing device of the device) to selectively block (and back up) or release the object inlet flow. Preferably, the locking device can have a movable (e.g., extendable or rotatable) locking element (e.g., a locking finger, a locking pin, or a locking barrier) for blocking the object of the object inlet flow. The locking device can advantageously prevent the transport path from becoming full of objects in case of a failure. Instead, the locking device can back up the objects on the inlet conveyor until the failure is repaired. Then, the backed-up objects can be successively picked up and carried away by the moving devices in the inlet region, preferably without gaps.

[0028] In one exemplary embodiment, the device further has a processing device configured to operate a plurality of magnetic segments and / or magnetic units as follows, - The object holders of the plurality of moving devices can take over a continuous or substantially continuous object inlet flow (e.g., in the inlet region of the device), optionally - The moving devices increase or decrease the distance between adjacent conveyed objects from the inlet region to the outlet region of the device, preferably to a predetermined object distance (e.g., equal to the predetermined pitch of the conveying elements of the outlet conveyor of the device).

[0029] This also advantageously enables the implementation of a control system for the transfer of objects by a moving device from a continuous inlet flow.

[0030] Preferably, the term “processing device” may refer, depending on the configuration, to an electronic system (e.g., as a driver circuit, or configured using a microprocessor and data memory) capable of performing open-loop and / or closed-loop control tasks and / or processing tasks. The term “control” as used herein may include, or be understood as, “closed-loop control” or “feedback control” and / or “processing,” as these. The processing device may be, for example, a central processing device, or it may have multiple decentralized or distributed processing units.

[0031] Further embodiments relate to container processing systems (for example, manufacturing, washing, coating, testing, rinsing, filling, sealing, pasteurizing, decorating, labeling, printing, marking, laser marking, and / or packaging containers for changing the temperature of liquid or paste-like media, preferably beverages, liquid foods, or products from the pharmaceutical or healthcare industry). The container processing system may have the apparatus disclosed herein. The container processing system may be, for example, a beverage filling plant.

[0032] For example, containers can be made up of bottles, cans, canisters, cartons, flasks, vials, tubes, and so on.

[0033] Further embodiments relate to methods and / or apparatus disclosed herein for transporting objects, preferably containers. The method includes transporting objects along a transport path by object holders of a plurality of moving devices. - The transport path is located inside the circulating drive path. -Multiple moving devices (e.g., permanent) magnetic units are driven by magnetic interaction with multiple (e.g., fixed) (e.g., electric or permanent) magnetic segments (e.g., long stator segments) arranged in a closed (e.g., preferably (e.g., circular) ring shape or elliptical) path curve to move along a cyclic drive path, and - The cyclic drive path is positioned outside (or encloses) the closed path curve.

[0034] Conveniently, the method can achieve the same advantages already described herein with reference to the apparatus. The same is true for the preferred example of the method described below.

[0035] In one exemplary embodiment, the method is: - The transfer of an object from a continuous or nearly continuous object inlet flow (e.g., a sub-flow of the entire flow) to an object holder of multiple moving devices, -Transferring objects to an object outlet flow by object holders of multiple moving devices, wherein adjacent objects are positioned at a predetermined object distance from each other. -The object being transported is pressed by the object holders of multiple moving devices, preferably on a curved support plate and / or preferably along curved lateral guide elements. - Preferably, the locking device further includes blocking the object inlet flow to the plurality of moving devices in at least one of the following cases: an error during transport, takeover, or transfer; failure of one of the plurality of moving devices; failure of one of the plurality of magnetic segments; failure of a device located downstream of the plurality of moving devices for processing and / or transporting the object; damage to the object detected; operator input.

[0036] Furthermore, objects can be successively brought in at arbitrary distances, for example, from an object inlet stream containing a container, to an object holder.

[0037] The preferred embodiments and features of the present invention described above can be combined with each other as needed. In particular, all features described in relation to the apparatus are also applicable and claimable in combination with the method, and vice versa. Further details and advantages of the present invention are described below with reference to the accompanying drawings. The drawings are as follows. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0039] The embodiments shown in the drawings correspond at least partially, and similar or identical parts are denoted by the same reference numerals. To avoid repetition, please also refer to the descriptions of other embodiments or drawings for explanation.

[0040] Figures 1 to 6 show a device 10 (or a part thereof) for transporting objects (articles) 12. The objects 12 are preferably embodied as individual containers or bundles of containers. Particularly preferably, the device 10 is included in a container processing system.

[0041] Apparatus 10 will be described in more detail below with reference to Figures 1 to 6. Figure 1 shows a schematic diagram of apparatus 10. In contrast, Figures 2 to 6 show perspective views of preferred exemplary embodiments of apparatus 10.

[0042] The apparatus 10 has a (for example, intermediate) conveyor (transport device) 30 having a plurality of magnetic segments 36 and a plurality of moving devices 38. Optionally, the apparatus 10 may further have, 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).

[0043] The entrance conveyor 14 can transport the object 12 to the conveyor 30.

[0044] The entrance conveyor 14 can transport the objects 12 preferably in an upright position and / or support them at their base. Preferably, the entrance conveyor 14 may be a linear conveyor. Preferably, the entrance conveyor 14 can transport the objects 12 in a line one after the other. The entrance conveyor 14 is preferably a single lane.

[0045] 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 substantially or almost gapless relative to each other. Preferably, adjacent objects 12 can be in contact with each other.

[0046] For example, the entrance conveyor 14 may have a circulating transport element 16. The circulating transport element 16 may be, for example, a belt, a plate transport element, a mat transport element, or a chain transport element.

[0047] The circulating transport element 16 may be guided and driven, for example, within the frame 18 of the inlet conveyor 14 (see Figures 2 and 3). The frame 18 may be open or enclosed. For example, the frame 18 may be enclosed within a closed housing, preferably a transport element box (e.g., a chain box).

[0048] For example, the drive wheel and multiple deflection wheels 20 may be rotatably mounted within / on the frame 18 (see Figure 2). The drive wheel can drive and guide the circulating transport element 16 to transport the object 12. The deflection wheels 20 can guide the circulating transport element 16, for example, in the corner region of the frame 18.

[0049] Preferably, the frame 18 of the entrance conveyor 14 may have a notch 22 for accommodating a portion of the conveyor 30 (see Figures 2 and 3). Preferably, the notch 22 may be located in the entrance area 32 of the conveyor 30.

[0050] The notch 22 can span a portion of the conveyor 30. For example, the notch 22 can span a portion of the conveyor 30 in a bridge-like manner. For example, the notch 22 can span a portion of the magnetic segment 36 of the conveyor 30. The notch 22 may be substantially rectangular, for example.

[0051] Preferably, the notch 22 can form a space for movement for a portion of the moving device 38 to pass through. For example, during the operation of the device 10, the connecting structure 46 of the moving device 38 (e.g., their cantilevers 50, see Figures 4-6) can move through the notch 22 or the space for movement formed by the notch 22.

[0052] For example, at least one deflection wheel 20 of the inlet conveyor 14 can be positioned to guide the circulating transport element 16 along or following the notch 22 (see Figure 2).

[0053] The notch 22 may preferably be located in the return travel section or the lower travel section of the inlet conveyor 14. Particularly preferably, the notch 22 may be located in the lower return travel section of the inlet conveyor 14.

[0054] The sensor device 24 is shown in Figure 1 as an example only. For example, the sensor device 24 may have one sensor or multiple sensors spaced apart from each other. Preferably, the sensor device 24 may be positioned adjacent to the entrance conveyor 14 or directly above the entrance conveyor 14.

[0055] The sensor device 24 can detect objects 12 in the object inlet flow. Preferably, the sensor device 24 can detect when a particular object 12 is passing a specific position along the inlet conveyor 14. However, the 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 of the objects 12 from each other.

[0056] The signal output from 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 moving device 38 for taking over the object 12.

[0057] The exit conveyor 26 is shown in Figure 1 as an example only. The exit conveyor 26 can transport the objects 12 away from the conveyor 30. Preferably, the exit conveyor 26 can take over the objects 12 in the (object) exit area 34 of the conveyor 30 and carry them away.

[0058] The exit conveyor 26 may have, for example, multiple conveying elements 28. The object 12 can be conveyed by the conveying elements 28. Specifically, the conveying elements 28 can successively convey the exit flow of the object 12 away from the exit region 34 of the conveyor 30.

[0059] The transport element 28 may be configured, for example, as an object holder, preferably a container holder. Preferably, each transport element 28 may have a support plate on which the object 12 can be placed upright. Alternatively or additionally, the transport element 28 may have a clamp or gripper that can hold the object 12 by its sides, neck, and / or neck ring.

[0060] The transport element 28 is movable to transport the object 12. The exit conveyor 26 is particularly preferably configured as a rotary conveyor. The transport element 28 can be moved along the circular path of the rotary conveyor to transport the object 12.

[0061] Preferably, the exit conveyor 26 itself is part of the object processing device for processing the object 12. For example, the object processing device can fill, seal, or decorate (e.g., label) the object 12, which is preferably configured as a container, while conveying the object 12 by the conveying element 28.

[0062] For example, the object processing device may be configured as a filling device for filling an object 12. The filling device may include an outlet conveyor 26. The filling device can fill the object (e.g., a container) 12 with a preferably liquid or paste-like medium. The filling device is preferably configured as a rotary filling device. The filling device may have a plurality of filling valves for filling a plurality of objects 12 simultaneously or in overlapping time. For example, the filling valves may be arranged around the filling carousel of the rotary filling device.

[0063] Alternatively, the object processing device may be, for example, a closing device for closing the object 12. The closing device may include an outlet conveyor 26. The closing device can close the object (e.g., container) 12 with, for example, a lid, cork, crown cork, or screw cap. The closing device may preferably be configured as a rotary closing device. The closing device may have multiple closing stations for closing multiple objects 12 simultaneously or in overlapping time. For example, the closing stations may be arranged around a closing carousel of a rotary closing device.

[0064] Alternatively, the object processing 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 can mark the object (e.g., a container) 12 with, for example, 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 transport element 28 may be configured as, for example, a rotatable object receptacle (e.g., object turntable) for the object 12, arranged around the marking carousel of the rotary marking device. The transport element 28 can be moved to pass through at least one marking unit of the marking device with the object 12 received in or on it. At least one marking unit may be arranged around the rotary marking device, for example.

[0065] Preferably, adjacent transport elements 28 are arranged at a predetermined (divided) fixed pitch relative to each other.

[0066] The conveyor 30 can transport the object 12 from its entrance area 32 to its exit area 34. In the entrance area 32, the conveyor 30 can take over the object 12 from the entrance conveyor 14. In the exit area 34, the conveyor 30 can transfer the object 12 to the exit conveyor 26. Preferably, the conveyor 30 can be configured as a transport star wheel that can transport the object 12 along a circular path.

[0067] The conveyor 30 has a plurality of magnetic segments 36 and a plurality of moving devices 38. Optionally, the conveyor 30 may also have, for example, support plates 54 and / or lateral guide elements 56 (see Figures 2 and 3).

[0068] The magnetic force segments 36 are arranged in a line along a closed (path) curve. The path curve or arrangement of the magnetic force segments 36 may be circular ring-shaped, for example, as illustrated in Figure 1. Alternatively, the path curve or arrangement of the magnetic force segments 36 may be elliptical, for example.

[0069] Preferably, all magnetic force segments 36 are arranged at the same height. The path curve can preferably be located in the horizontal plane.

[0070] For example, each magnetic segment 36 has one or more magnets, such as permanent magnets or electromagnets. Preferably, the magnetic segments 36 are stationary or fixed in a predetermined position.

[0071] Preferably, the magnetic force segments 36 or their magnets are oriented outward with respect to the closed path curve.

[0072] The moving device 38 is used to transport the objects 12. The moving device 38 is also called a mover or shuttle. Preferably, each object 12 may be transported individually by one of the moving devices 38. Alternatively, for example, multiple objects 12 may be transported by each moving device 38, or multiple moving devices 38 may transport together, for example, one object 12 held between multiple moving devices 38.

[0073] Each moving device 38 has a magnetic force unit 40 and an object holder 44 for holding (at least) one object 12 during transport. Optionally, each moving device 38 may have a connecting structure 46.

[0074] The magnetic force unit 40 is used for magnetic interaction with multiple magnetic force segments 36 in order to drive each of the moving devices 38.

[0075] For example, each magnetic force unit 40 has one or more magnets, such as permanent magnets or electromagnets. Preferably, the magnetic force units 40 or their magnets can be partially or completely housed within the housing 42 of each mobile device 38.

[0076] The magnetic force unit 40 is positioned outside the magnetic force segment 36, or outside the closed path curve in which the magnetic force segment 36 is located. The magnetic force unit 40 is positioned to move along the circulating drive path A. The drive path A is therefore positioned outside the closed path curve in which the magnetic force segment 36 is located, or outside the magnetic force segment 36.

[0077] For example, the magnetic force units 40 or their magnets may be oriented toward the closed path curve in which the magnetic force segments 36 are positioned. The magnetic force segments 36 and the magnetic force units 40 may be directly opposite each other.

[0078] Preferably, the magnetic force units 40 can be driven independently of or individually by the magnetic force segments 36. Thus, the moving devices 38 can be moved independently of each other and driven magnetically individually.

[0079] For example, the moving device 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 conveyor 30. That is, the magnetic force unit 40 and the magnetic force 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.

[0080] The conveyor 30 is particularly preferably configured as a long-stator linear motor conveyor. The magnetic force segment 36 can be configured as a long-stator segment. Together, the long-stator segments can preferably form a ring-shaped or elliptical long stator (for example, a circular one). Each long-stator segment may have an electromagnet for causing the movement or driving of the magnetic force unit 40, which is equipped with permanent magnets.

[0081] However, for example, the conveyor 30 can also be a short-stator linear drive conveyor or a planar motor conveyor.

[0082] In a short-stator linear motor conveyor, the magnetic force segment 36 and the magnetic force unit 40 can together form a short-stator linear motor drive system. The magnetic force unit 40 may have electromagnets for forming a short stator, which can magnetically interact with the fixed permanent magnets of the magnetic force segment 36 to drive each moving device 38.

[0083] The planar motor conveyor can move a moving device 38 in at least two degrees of freedom (circumferential and z-direction) on a preferably closed drive surface of a stator consisting of magnetic segments 36 (not shown in Figure 1). The magnetic segments 36 and magnetic units 40 can together form a planar motor drive system. The stator consisting of the magnetic segments 36 is also called a platform or base element. Lifting and / or tilting movements of the moving device 38 relative to the stator / base element can also be controlled by magnetic interaction. The base element can preferably be segmented into tiles. The stator or magnetic segments 36 may be formed, for example, by movable, for example, rotatable permanent magnets, or by stationary electromagnets. The magnetic units 40 preferably have permanent magnets.

[0084] The object holder 44 may be active or passive.

[0085] Preferably, the object holder 44 has at least one object pocket (object receptacle or object tray) that can contact the object 12 by contacting the neck and / or side (body) of the object 12. The object 12 can be at least partially housed in the object pocket, preferably a container pocket. For example, the object 12 can be pushed by the object pocket and thus transported when the respective moving device 38 is moved. Alternatively, the object holder 44 may have, for example, a support plate on which the object 12 can stand upright. Alternatively or additionally, the object holder 44 may have a clamp or gripper on which the object 12 can be held by its side, neck, and / or neck ring.

[0086] The object holder 44 is positioned to transport the held object 12 on a transport path T that is inside the circulating drive path A.

[0087] For example, the object holder 44 can be positioned inside the circulating drive path A, the closed path curve, the transport path T, the magnetic force unit 40, and / or the magnetic force segment 36.

[0088] Preferably, the object holder 44 may be oriented outward to hold the object 12. In the top view of the device 10, it is preferable that the object 12 can be positioned between the object holder 44 of each moving device 38, which is preferably located on the inside, and the magnetic force unit 40 of each moving device 38, which is preferably located on the outside.

[0089] Preferably, the object holder 44 is positioned at a different height from the magnetic force unit 40 and the magnetic force segment 36. For example, the object holder 44 can be positioned above or below the magnetic force unit 40 and the magnetic force segment 36. Thus, the transport path T can be positioned at a different height from the circulating drive path A, for example, above or below it. In the exemplary embodiments shown in Figures 2 to 6, the object holder 44 is positioned, for example, above the magnetic force unit 40 and the magnetic force segment 36, thereby positioning the transport path T above the drive path A.

[0090] The connection structure 46 can connect the object holder 44 of each moving device 38 to the magnetic force unit 40 of each moving device 38. The connection structure 46 is preferably rigid. Preferably, the connection structure 46 can transmit the movement of the magnetic force unit 40 to the object holder 44.

[0091] For example, the upper end of the connection structure 46 can be directly connected to the object holder 44, and the lower end of the connection structure 46 can be directly connected to the magnetic force unit 40 and / or housing 42, or vice versa.

[0092] Preferably, for replacement purposes, the object holder 44 can be detachably attached to the connection structure 46, for example, in the upper end region of the connection structure 46, via screws, plugs, and / or clamp connections.

[0093] The object holder 44 is preferably connected to the connecting structure 46 in a height-adjustable (e.g., vertically movable) manner. For example, the connecting structure 46, for example, the upper end region of the connecting structure 46, can be connected to the object holder 44 via vertical guides and / or dovetail joints. Preferably, the object holder 44 can be fixed to the connecting structure 46 at different height positions, preferably in a stepless manner.

[0094] Preferably, for replacement purposes, the housing 42 and / or magnetic unit 40 can be detachably attached to the connection structure 46, for example, to the lower end region of the connection structure 46, via, for example, screws, plugs, and / or clamp connections.

[0095] Preferably, the magnetic force unit 40 is connected to the connecting structure 46 in a height-adjustable (e.g., vertically movable) manner, for example, via a housing 42. For example, the lower end region of the connecting structure 46 may be connected to the magnetic force unit 40 and / or housing 42 via vertical guides and / or dovetail joints. Preferably, the magnetic force unit 40 can be fixed to the connecting structure 46 at different height positions, preferably in a stepless manner.

[0096] For example, the connecting structure 46 may have an elongated carrier 48 and a cantilever 50 (see, for example, Figures 3 to 6).

[0097] The elongated carrier 48 may be, for example, a rod, pole, beam, or strip. Preferably, the elongated carrier 48 is a vertical carrier. The carrier 48 may preferably be positioned inward relative to the object holder 44 or the transport path T. Preferably, the carrier 48 may have an upper end region to which the object holder 44 is removablely attached, for example, via vertical guides and / or dovetail joints, or simply screwed together.

[0098] The cantilever 50 can preferably be positioned directly beneath the object holder 44 of each moving device 38. For example, the cantilever 50 can extend from the carrier 48, for example, radially outward and / or toward the housing 42 and / or magnetic unit 40 of each moving device 38.

[0099] The cantilever 50 can connect the carrier 48 and the magnetic unit 40, for example, via a housing 42. Preferably, the housing 42 and / or the magnetic unit 40 may be located at one end of the cantilever 50. Preferably, the housing 42 and / or the magnetic unit 40 may be removably attached to the end of the cantilever, for example, via a vertical guide and / or dovetail joint, or by screwing or welding.

[0100] Preferably, the cantilever 50 can support the housing 42 and / or the magnetic unit 40 on the carrier 48. At a minimum, the cantilever 50 can transfer the movement of the magnetic unit 40 to the carrier 48 and therefore to the object holder 44.

[0101] Preferably, the connecting structure 46 can be configured as a truss at least partially. For example, the cantilever 50 can be implemented as a truss structure.

[0102] Preferably, the connecting structure 46 is positioned above the magnetic segment 36. For example, the carrier 48 and / or cantilever 50 can be positioned above the magnetic segment 36, preferably directly above the magnetic segment 36.

[0103] The moving device 38 can be guided and optionally supported on a central guide column 52 (see, for example, Figures 2 and 3). The guide column 52 can be located, for example, in the center inward with respect to the transport path T and / or drive path A.

[0104] For example, the moving device 38 may be guided and supported on the guide column 52 via a connecting structure 46. Preferably, the connecting structure 46 may be rotatably connected to the guide column 52, for example, via a carrier 48.

[0105] The moving devices 38 guided on the central guide column 52 preferably do not have rollers. Alternatively, for example, multiple moving devices 38 may each have at least one guide roller, which guides and optionally supports each moving device 38 along a circulating guide track (not shown). At least one guide roller may be located, for example, on the connecting structure 46 and / or on the housing 42 and / or on the object holder 44.

[0106] The support plate 54 can be used to support the object 12 held by the object holder 44 from below (see Figures 2 and 3). For example, during transport, the object 12 can be pushed onto the curved support plate 54 by the object holder 44 of the moving device 38.

[0107] Preferably, the support plate 54 may have a curved course that follows the transport path T. Preferably, the support plate 54 may be positioned directly below the transport path T. For example, the support plate 54 may be positioned between the object holder 44 and the magnetic segment 36.

[0108] The lateral guide element 56 can be used to guide the object 12, held by the object holder 44, laterally along the transport path T (see Figures 2 and 3). For example, during transport, the object 12 may be pushed along the lateral guide element 56 by the object holder 44 of the moving device 38.

[0109] For example, the lateral guide element 56 may be a lateral rail or a side wall. Preferably, the lateral guide element 56 may be positioned outside the object holder 44 and / or the transport path T. For example, the lateral guide element 56 may have a curved course that follows the transport path T.

[0110] The locking device 58 is shown in Figure 1 as an example only. The locking device 58 can be selectively activated to block or release the inlet flow of the object 12. The released inlet flow can enter the conveyor 30 so that the object 12 can be taken over by the moving device 38. The inlet flow can be blocked by the locking device 58 before entering the conveyor 30, and as a result the object 12 is not taken over by the moving device 38. The object 12 in the inlet flow can then be backed up instead. The locking device 58 can be operated, for example, by the processing device 60.

[0111] Preferably, the locking device 58 can be positioned within the entrance area 32 and / or at the end of the entrance conveyor 14. For example, the locking device 58 can be positioned to block the object 12 while it is positioned on / standing on the entrance conveyor 14 or being transported by the entrance conveyor 14. Alternative or additional barriers can also be positioned further upstream (for example, to perform at least a partial function). This function can, in some cases, also be achieved by lateral overlap.

[0112] The locking device 58 can be activated to shut off the inlet flow when, for example, an error during transport, a failure of one of the multiple moving devices 38, a failure of one of the multiple magnetic segments 36, damage to the object 12, a corresponding operator input, and / or a failure of a device located downstream of the conveyor 30 for processing and / or transporting the object 12 (e.g., a filling device, a closing device, or a marking device).

[0113] The locking device 58 may have, for example, a movable (mechanical) locking element for blocking the object 12. The locking element may be, for example, a locking finger, a locking pin, or a locking barrier.

[0114] The locking element may be movable, for example, between a locked position and an open position. In the locked position, the object 12 can be locked. In the locked position, the locking element can be used as a stopper for the (forward) object 12. In the open position, the object 12 can be released for transport and entry into the conveyor 30.

[0115] Preferably, the locking element can be moved by an actuator of the locking device 58. The actuator may be, for example, a mechanical, pneumatic, hydraulic, electric, or electromagnetic actuator. The mobility of the locking element may be, for example, that it can be extended, retracted, and / or pivoted. Damping incorporated into the locking element is also possible. The actuator may be operated by, for example, a processing device 60.

[0116] The processing device 60 is shown in Figure 1 as an example only. The processing device 60 may be configured to operate the apparatus 10.

[0117] For example, the processing device 60 can be signal-connected to the inlet conveyor 14, the sensor device 24, the outlet conveyor 26, the conveyor 30, the magnetic segment 36, the magnetic unit 40, and / or the locking device 58.

[0118] Preferably, the processing device 60 can operate the magnetic segment 36 and / or magnetic unit 40 so that the object holders 44 of the multiple moving devices 38 can take over a continuous or substantially continuous inlet flow of objects in the inlet region 32. Optionally, the moving device 38 can increase the distance between adjacent objects 12 being transported from the inlet region 32 to the outlet region 34, preferably to a predetermined object distance corresponding to the pitch of the outlet conveyor 26. The moving device 38 can then transport the objects 12 to the transport elements 28 of the outlet conveyor 26 at that pitch.

[0119] Figure 7 schematically illustrates how the arrangement of the inner transport path T relative to the drive path A can have a favorable effect.

[0120] Adjacent magnetic units 40 (and therefore associated moving devices 38) can be moved closer to each other so 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, it is preferable that the housings 42 in which the magnetic units 40 are housed are not yet in contact.

[0121] The proximity of the object holder 44 and the object 12 in the area ultimately allows the object holder 44 to take over the object 12 from the substantially or nearly continuous inlet flow from the inlet conveyor 14.

[0122] Therefore, the object holder 44 and the housing 42 in which the magnetic force unit 40 is housed can be sized such that when they move together, the object holder 44 and / or the object 12 come into contact with each other, while the housing 42 remains separated from each other.

Rather, multiple variations and modifications are possible that similarly utilize the concepts of the present invention and thus fall within the scope of protection. Specifically, the present invention also claims protection to the subject matter and features of dependent claims, regardless of the claims referred to by the dependent claims.
