[0041] FIG. 3 a view of the system as in FIG. 2, wherein the slide function units provided for the sliding of the packaging means are represented in a further possible position setting, and

[0042] FIG. 4 on the basis of an exemplary schematic diagram, a possible variant of step sequences for the layer formation.

[0043] Identical reference numbers are used in the figures for elements of the invention which are the same or have the same effect. Furthermore, for the sake of easier overview, only reference numbers are shown in the individual figures which are required for the description of the respective figure. The invention is also represented in the figures only in a schematic view for the explanation of the mode of operation. In particular, the representations in the figures serve only to explain the basic principle of the invention. For reasons of easier overview, the representation of all the constituent parts of the device has been avoided.

[0044] The system designated in the figures in general by 1 serves to assemble layers LA of packaging means 2, and to form transport and storage units 100 from at least one of these layers LA. In particular, the system 1 described and represented in the figures is an arrangement or a system of devices or machines which are suitable for the packing and/or palletising of packaging means 2 or to produce units or bundles which are capable of storage and transport. In the widest sense, therefore, the system 1 can also be understood as a packaging and/or palletising system.

[0045] The exemplary system 1 is especially well-suited for the handling and processing of packaging means 2 formed as liquid containers, in particular for beverage containers, such as beverage cans, such that the system 1 can preferably be used in the beverage industry, and can, for example, also be a part of a beverage filling system. In particular, it is possible with the system 1 described here for beverage cans 2 which are already filled or are to be filled to be assembled to form layers LA, and, from these layers LA of filled beverage cans, finally for transport and storage units 100 to be formed. In the meaning of the present invention, the filled beverage cans are also designated as full cans, such that the assembling of layers LA and the formation of transport and storage units 100 can also be understood in this case as a full can palletising process.

[0046] Shown in a rough schematic and highly simplified form in FIG. 1 is an exemplary embodiment of a system 1, sketched in a view from above. The system 1 comprises a grouping station 3 and a layer stacker 11 downstream of the grouping station 3 in the conveying direction FR. In the grouping station 3 the packaging means 2 which conveyed are essentially assembled to the desired layers LA and transferred to the layer stacker 11, where the assembled layers LA are pushed onto specially provided plates 110, provided in the layer stacker 11, with the formation of the transport and storage unit 100.

[0047] The grouping station 3 of the system 1 represented by way of example in FIG. 1 comprises a grouping table 4, which defines with its upper side and with its upper surface a grouping plane EG, and, with at least one part section of this upper side, forms a preparation place or collection zone for the ordering and grouping of the packaging means 2. The grouping table 4 is configured in the example represented as being essentially rectangular, and extends in its length along the conveying direction FR, wherein opposing longitudinal sides oriented in the conveying direction FR form a first and second side 8, 9 of the grouping table 4.

[0048] The grouping station 3 further comprises a packaging means delivery device 5 for delivering the packaging means 2 to the grouping table 4, wherein the packaging means delivery device 5, in the example represented in FIG. 1 comprises two double row conveyors 6, 6′ for transporting in each case two packaging means rows running next to one another. The double row conveyors 6, 6′ are arranged in the conveying direction FR on both sides of the grouping table 4, i.e. the first double row conveyor 6 runs on the first side 8 of the grouping table 4 and the second double row conveyor 6′ runs on the second side 9 of the grouping table 4.

[0049] As a result of this two-side arrangement of the double row conveyors 6, 6′, the delivery of the packaging means 2 to the grouping table 4 from two opposing sides 8, 9 takes place in a symmetrical manner. In the exemplary embodiment represented here, the two double row conveyors 6, 6′ are arranged parallel to one another, as well as parallel to the first and second sides 8, 9 of the grouping table 4, and are oriented along their length in the conveying direction FR. Not represented in FIG. 1, on the inlet side, a packaging means inlet is provided, at the inlet end of the double row conveyors 6, 6′, facing away from the grouping table 4, which delivers the packaging means 2 in a mass flow, namely in an unordered manner in bulk to the double row conveyors 6, 6′. From the mass flow of the packaging means inlet, the packaging means 2 go over, in a known manner, at a transfer point on to the double row conveyors 6, 6′, into a line or row transport system.

[0050] The double row conveyors 6, 6′ which transport the packaging means 2 standing upright, in particular the filled beverage cans, form for this upright transport of the beverage cans 2 a transport plane, which essentially lies at the same height as the group plane EG of the grouping table 4, and coincides with this in a common plane. The double row conveyors 6, 6′, extending from their inlet end as far as a transfer end arranged on the outlet side, are essentially arranged upstream of the grouping table 4 in the conveying direction FR, but overlap in sections, related to the conveying direction FR, with the region of their transfer end, with the grouping table 4.

[0051] Each double row conveyor 6, 6′ comprises a dividing device 12 for compartmentalising or separating a predetermined number of the packaging means 2 running behind one another in a row, the number being dependent on the respective layer arrangement which is to be formed, from the packaging means flow or from the respective packaging means row, such that the packaging means 2 being transported in the conveying direction FR are grouped by means of the double row conveyors 6, 6′ on the outlet side at the transfer end, to form a packaging means preliminary group G. Also provided at the dividing device 12 is an alignment means for aligning the row, which arranges the two packaging means rows in each packaging means preliminary group G offset to one another as a dependency of the layer arrangement which is to be formed, such that the leading end of the packaging means preliminary group G is formed in a stepped manner or with an offset, and the packaging means 2 of a row stand essentially at gaps in relation to the packaging means 2 of the adjacent row. In the regions of the transfer ends of the respective double row conveyors 6, 6′, arranged overlapping with the grouping table 4, the pre-grouped packaging means groups G therefore stand ready for the slide over onto the grouping table 4.

[0052] Provided in these overlapping regions, on each side 8, 9 of the grouping table 4, between the respective double row conveyor 6, 6′ and the grouping table 4, is in each case a slide-over buffer region 10, over which the packaging means 2, in particular the packaging means groups G, are slid from the respective transfer end of the double row conveyors 6, 6′ in a respective slide direction SR1, SR2 onto the grouping table 4. Preferably, the slide-over buffer region 10 is formed by a slide-over plate with a flat and smooth upper side, wherein the upper side of the slide-over plate 10 defines a slide plane which essentially coincides with the grouping plane EG and with the transport plane. The respective width of the slide-over buffer regions 10 preferably amounts to at least approximately four times the diameter of the packaging means 2 which are to be processed, such that the slide-over buffer region 10 can encompass, for example, two of the packaging means groups G, each consisting of a double row.

[0053] For the slide-over function, and for the transfer of the packaging means 2 or packaging means groups G from the respective row conveyors 6, 6′ to the grouping table 4, the grouping station further comprises a transfer unit 7, the structure and function of which are explained in greater detail in connection with FIGS. 2 and 3. FIGS. 2 and 3 show in this situation a rough schematic and highly simplified view of an exemplary embodiment of the system 1, wherein the transfer unit 7 provided for the sliding of the packaging means 2 can be seen. As has already been explained, the transfer unit 7 slides the packaging means 2 from the respective row conveyor 6, 6′ in a respective sliding direction SR1, SR2 onto the grouping table 4, in order to form there the layer LA from the packaging means 2, wherein each layer LA is produced in accordance with a desired predetermined layer arrangement or in accordance with a desired predetermined layer pattern by way of the transfer unit 7.

[0054] The transfer unit 7 comprises a transverse carrier element 7.1, in the form of a guide rail secured to parts of the machine frame, with a main axis HA, which, seen in a vertical direction, is arranged above the grouping table 4, located at a specified higher height level from the grouping plane EG, in such a way that the main axis HA runs essentially parallel to the grouping plane EG. The transverse carrying element 7.1 extends in relation to the conveying direction FR, which in the representation in FIGS. 2 and 3 run into the paper plane and is not identifiable, transversely over the grouping table 4 and the slide-over plates 10, connecting with this on both sides, and the respective row conveyor 6, 6′, adjacent to the slide-over plates 10, wherein the main axis HA of the transverse carrier element 7.1 is oriented essentially perpendicular to the conveying direction FR.

[0055] Provided at the transverse carrier element 7.1 are slide function units 13, 14, mounted such as to be movable and driven by motor and pneumatic means. In this situation, essentially the first slide function unit 13 is assigned to the first side 8 of the grouping table 4, and the second slide function unit 14 is assigned to the second side 9 of the grouping table 4. Each slide function unit 13, 14, comprises in each case a pair of interacting raising and lowering slide elements 13.1, 13.2, 14.1, 14.2. For example, the respective first slide elements 13.1, 14.1 take effect on each side 8, 9 as sliding or pressing elements, which slide or press the packaging means 2 or the packaging means groups G, or larger packets formed in turn from several packaging means groups G, in the respective slide direction SR1, SR2. The respective second slide elements 13.2, 14.2 on each side 8, 9 take effect in this situation as stops or pick-ups or counter-holders, which hold or guide the corresponding packaging means groups G or the packets moved by the slide elements 13.1, 14.1 in the slide direction SR1, SR2.

[0056] Each slide element 13.1, 13.2, 14.1, 14.2 is driven in this situation individually and independently, and specifically both for the raising and lowering movement in the vertical direction as well as for the travel movement in the horizontal direction. Each slide element 13.1, 13.2, 14.1, 14.2 can therefore be moved at least in sections along the transverse carrier element 7.1 in the direction of the main axis HA, and specifically in the respective slide directions 13.1, 13.2, 14.1, 14.2 in each case over a specific section, preferably over at least a quarter or at least a third or at least the half of the length of the transverse carrier element 7.1, by means of a lateral travel movement to-and-fro in the horizontal direction, in particular steplessly.

[0057] The slide elements 13.1, 13.2, 14.1, 14.2 are moved in this situation in a controlled manner, wherein the system 1 comprises a control unit (not shown in the Figures), and the movement of the slide elements 13.1, 13.2, 14.1, 14.2 is individually controlled by means of this control unit. In this situation, each slide element 13.1, 13.2, 14.1, 14.2 can be controlled individually and independently, such that both the vertical raising and lowering movement as well as the horizontal lateral travel movement can take place individually and independently at each slide element 13.1, 13.2, 14.1, 14.2. In the example shown, each slide element 13.1, 13.2, 14.1, 14.2 comprises an individual motor drive 15, in particular a servomotor, which is connected by respective toothed belts to the slide elements 13.1, 13.2, 14.1, 14.2. Shown in FIG. 1 are the four servomotors 15, individually assigned to the slide elements 13.1, 13.2, 14.1, 14.2. In FIGS. 2 and 3 only two are to be seen, the other two being concealed from view. In the examples shown, each slide element 13.1, 13.2, 14.1, 14.2 likewise comprises its own independent pneumatic drive for the vertical raising and lowering movement, and specifically in the form of a respective pneumatic cylinder unit, consisting in each case of two cylinders 18a, 18b.

[0058] In the representation in FIG. 2, all the slide elements 13.1, 13.2, 14.1, 14.2 are in a lowered position, in which the packaging means 2 or the packaging means groups G or packets can be taken into engagement. Likewise, the slide elements 13.1, 13.2 of the first slide function unit 13 are located in the region above the double row conveyor 6, and those slide elements 14.1, 14.2 of the second slide function unit 14 are located in the region above the double row conveyor 6′. In this position, each slide function unit 13, 14 can “grip” and slide a packaging means preliminary group G at the respective transfer end of the double row conveyor 6, 6′.

[0059] In the representation in FIG. 3, the slide elements 13.2 and 14.2 are in a raised position, in which they are located above the packaging means 2 or the packaging means groups G or packets, and in which, for example, return travel to the respective sides 8, 9 or double row conveyors 6, 6′ can take place unhindered during the layer formation, even if the layer LA of packaging means 2 which is being formed is located on the grouping table 4. The slide elements 13.2, 14.2 are likewise located in the region of the centre of the collection zone of the grouping table 4.

[0060] A guide means 16, serving as an outer delimitation and in the form of an outer railing or a guide strip is provided for the packaging means guide 5 laterally at the double row conveyors 6, 6′, which interacts with an internal railing 17 which can be raised or lowered, in order to guide the rows of packaging means 2 during transport. During the formation of the layers LA on the grouping table 4, in order for the layer LA which is produced in each case on the grouping table 4 to be stabilised with the maintaining of the layer pattern or the layer arrangement, further front and rear layer guides are provided, which in each case can be raised or lowered, which form a delimitation to the collection zone on the grouping table 4, and which extend essentially perpendicular to the conveying direction FR transversely over the grouping table 4. In order to slide the packaging means groups G from the double row conveyors 6, 6′ onto the grouping table 4, the internal railings 17, which can be raised and lowered, are lowered, as is represented in FIGS. 2 and 3. By way of example, during the pre-grouping of a packaging means preliminary group G at the transfer end of the double row conveyor 6, 6′, the internal railings 17 are in a raised position, in order to form a lateral stop, and to prevent a premature packaging means movement in the slide direction S1, S2. The lowering and raising of the internal railings 17 and layer guides also takes place in a controlled manner.

[0061] The function and mode of operation of the slide function units 13, 14 in the formation of layers can be explained in greater detail hereinafter by reference to FIG. 4 on the basis of a special example, wherein each of the sketches a) to l) of FIG. 4 represent a highly simplified view from above onto the grouping table 4, the slide-over plate 10, and the double row conveyor 6, 6′, of which, for reasons of easier overview, only sketch a) has been provided with reference numbers. By analogy, however, the same reference numbers also apply to the other sketches.

[0062] Sketches a) to l) of FIG. 4 represent individual steps of the layer formation, wherein, for reasons of easier overview, each row sketched of a packaging means preliminary group G, of a packet, or of a layer LA contains in each case only four packaging means 2. It is understood that the rows of a layer LA do as a rule comprise more than four packaging means, and exhibit, for example, 10, 11, or more packaging means.

[0063] In sketch a), which represents the initial state in the formation of a new layer LA, in each case a double row of packaging means 2 has already run in at the transfer end of the double row conveyor 6, 6′, and has already grouped to form a packaging means preliminary group G.

[0064] In this position, the slide function units 13, 14 move left and right to the packaging means preliminary group G, the respective slide elements 13.1, 13.2 “grip around” the corresponding packaging means preliminary group G on the double row conveyor 6, and the respective slide elements 14.1, 14.2 “grip around” the corresponding packaging means preliminary group G on the double row conveyor 6′. As soon as the slide elements 13.1, 13.2 and 14.1, 14.2 are securely in position, the internal railings 17 are lowered, the layer guides are brought into the blocking position, and each packaging means preliminary group G is pushed onto the slide-over buffer region 10 (sketch b)), while the next packaging means preliminary groups G are already being formed and stand ready at the transfer ends of the double row conveyors 6, 6′ (sketch c)). Next, the slide elements 13.1, 13.2 and 14.1, 14.2 guide the packaging means preliminary group G standing ready at the double row conveyors 6, 6′ as far as shortly before the contact with the respective packaging means preliminary group G on the slide-over buffer region 10, and the respective slide elements 13.2, 14.2, which serve as “collectors”, are raised and move inwards in the direction towards the middle of the grouping table 4, in order now to form a packet consisting of two packaging means preliminary groups G and slide further in the direction of the collection zone (sketch d)).

[0065] With approximately this sequence, the packets are constantly enlarged by new packaging means preliminary groups G, consisting in each case of two rows, and slid further in the direction of the collection zone (sketches e) to g)). Sketch h) shows a situation in which the packet which is “growing” at the right side of the sketch (which corresponds to the second side 9 of the grouping table 4), and which consists of eight double rows, has already moved into the centre of the collection zone of the grouping table 4, while (as shown in sketch i)) on the left side a further double row is being added, and, on the right side, the first packaging means preliminary group G, belonging to the next layer LA, is already “intermediate buffered” on the slide-over buffer region 10. In the representation in the sketches j) and k), the first layer LA is completed in the middle in the collection zone of the grouping table 4, while the packaging means preliminary groups G for the next layer are being slid over successively onto the slide-over buffer regions 10.

[0066] The completed layer LA runs out, guided by the corresponding layer guides (sketch l)), and specifically in the conveying direction FR to the layer stacker 11 downstream of the grouping station 3. During this period, too, the packets required for the next layer LA can already be being prepared and formed on the slide-over buffer regions 10, as a result of which both the evident saving of time and, in particular, an improved interference-free sequence in layer formation can be achieved. Since, as a result of this, the delivery and transport of the packaging means 2 runs essentially continuously, in particular the removal of the packaging means 2 out of the upstream mass flow is so regular that interruptions can be avoided.

[0067] The layer LA running out in the direction of the layer stacker 11 goes over to the layer stacker 11 with the layer order arrangement being retained, and is slid over here, in order to form the transport and storage unit 100, onto a plate 110 prepared in the layer stacker 11. This likewise takes place in a guided manner and with the retaining of the layer order arrangement and the layer pattern, wherein the sliding movement onto the plate 110 is carried out, for example, by a sliding and guiding unit in the form of a cage or frame. By means of centring units in the system 1, for example in the region of the layer stacker 11, the required position of the layer LA can be monitored and corrected.

[0068] Provided in the layer stacker 11 is a raising fork, which provides for each completed layer LA a respective plate 110 for receiving the layer LA. The raising fork is configured in this situation in such a way that it provides the plate 110 which is to be loaded at the corresponding height, namely preferably at the height of the grouping plane EG, such that a stepless slide over onto the plate 110 is possible.

[0069] A multilayer transport and storage unit 100, consisting of a plurality of layers is formed, for example, by the raising fork lowering the transport and storage unit 100, and a transfer device, likewise provided in the system, places a new plate 110 on top of the layer LA. By means of a height positioning device, it is ensured that the upper side of the “new” plate 110 lying on the layer is now aligned in the group plate EG of the grouping table 4 in such a way that a new layer LA, assembled in the grouping station 3, can be slid on.

[0070] The invention has been described heretofore on the basis of exemplary embodiments. It is understood that a large number of modifications or derivations are possible without thereby departing from the scope of protection of the invention defined by the claims. The contents of the claims are also declared to be the object of the description.
