DETAILED DESCRIPTION OF THE INVENTION
[0120] A possible embodiment of a bundle 1 according to the invention is shown in
[0121] In the example shown, for example, thin cardboard can be selected as the material for the carrier strand 11, which material is provided for example as a continuous web from a roll. Alternatively, another suitable material can also be selected, such as a plastics film having suitable stiffness, in such a case a biodegradable material advantageously being selected.
[0122] The carrier strand 11 has perforations 17 transversely to the longitudinal direction at regular intervals. These perforations divide the carrier strand 11 functionally into a plurality of packaging units 2, 2′, 2″, each having a flat carrier element 21. At the same time, local weaknesses of the mechanical stability of the carrier strand are formed along the perforations 17. The perforations therefore act as hinge elements, at which adjacent carrier elements 21 of the carrier strand 11 are pivotable relative to one another. This makes it possible for the bundle 1 to be able to be flexibly deflected perpendicularly to the longitudinal direction 10 and to the perforation 17, analogously to a chain. In this way it can for example be conveyed using a suitable device, as will be discussed below in conjunction with
[0123] The perforations can additionally also be used as predetermined breaking points 18 in order to separate a packaging unit 2 from the remaining bundle 1, as required. Such isolated packaging units 2, 2′, 2″ can then be inserted, for example, into a transport container of a conveying system without the goods unit being damaged or impaired in quality. For example, such a packaging unit can be inserted into an overhead conveyor bag of an overhead conveyor system.
[0124] A goods unit 3 in the form of a shirt 31 folded flat in a conventional form is arranged on each packaging unit 2, 2′, 2″. The goods units 3, 31 are connected to the carrier element 21 of the packaging unit 2, 2′, 2″ at four fastening points 24. For example, the shirt can be sewn onto the four fastening points 24 by a thread, or be attached to the packaging unit by means of a pin, or connected thereto in some other form-fitting manner.
[0125] It is also possible to use correspondingly suitable clamping elements which clamp the shirt 31 and the carrier element 21 of the packaging unit 2 together in a force-fitting manner via lateral edges, for example.
[0126] The stiffness of the entire combination of the packaging unit 2 and the goods unit 3 also contributes to the effective mechanical stability of the packaging unit. For a goods unit which already has a certain mechanical stability, the material of the carrier strand 11 can thus be selected to be thinner, for example.
[0127] In the example shown, in addition to the resulting mechanical stability of the packaging unit, the packaging unit 2 additionally has the effect that the edges of the goods units are protected during conveying and storage of isolated packaging units.
[0128] In the embodiment shown, data elements 23 in the form of optically readable barcodes are arranged on the carrier elements 21 of the packaging units. Alternatively, other data elements can also be used, such as two-dimensional QR codes or RFID elements. The data elements 23 can contain, for example, information on the type of the goods unit 3 contained in the packaging unit 2, data on the production sequence, such as batch number, date of production and production location, an individual identification number, or a reference to an entry in a database.
[0129] The data element 23 can, for example, be attached to the packaging unit 2 when the goods unit 3 is inserted. Alternatively, the data element 23 can be attached to the carrier element 21 independently of the goods unit 3, and later described with data in the production sequence. Corresponding data can also be assigned to a unique identification number in a database.
[0130] Another advantageous embodiment of a bundle 1 according to the invention is shown in
[0131] For goods units 3 such as the socks 31 shown, the risk of mechanical damage during insertion into a transport container 8 is fairly low. A bundle according to the invention is nevertheless advantageous for this, because it allows a very efficient provision of the goods units for later filling into transport containers of an intralogistics system.
[0132] Typically, goods units 3 are individually packaged during production and these isolated packaging units are in turn packed into a transport container, with which they then reach the processor, for example a mail order center, from the manufacturer. There, they are removed from the transport container and separated, manually or with special apparatuses adapted to the products, for further processing. By contrast, in the case of a bundle according to the invention, the goods units can already be inserted into the packaging units 2 of a bundle 1 according to the invention at the manufacturer, in the continuous production process. The resulting bundle can then be packaged and transported integrally. In the main order center, the bundle 1 can then be easily transferred into individual packaging units 2, which can then be transferred into transport containers of an overhead conveyor system for example.
[0133] It is also possible to provide bundles in flexible sizes, by producing the bundle as a continuous chain, from which bundles having the desired number of goods units are then separated.
[0134] For goods units 3 in which the mechanical stability of the packaging unit is secondary, it is possible, as explained above, for the carrier strand 11 to also be manufactured from a flexible material, for example as a flexible strip made of paper, plastics material or textile sheet material.
[0135] An alternative embodiment of a bundle according to the invention, and the production thereof, is shown in
[0136] The goods unit 3, 31 is now held in a form-fitting manner between a rear carrier element 21, which is formed by the original central region of the carrier strand 11, and the second carrier elements 22, 22′, which are formed by the folded-over original edge regions of the carrier strand 11.
[0137] The perforation line 17 transversely to the longitudinal direction 10 of the carrier strand 11 can either be attached before the outer edges 22, 22′ are folded over, or advantageously only after first and second carrier elements 21, 22, 22′ are connected.
[0138] Since the folded longitudinal edge and the double-layer carrier elements 21, 22, 22′ increase the mechanical stiffness compared with the single-layer carrier element 21 from
[0139] In another variant of such a bundle 1 according to the invention, the production of which is shown in
[0140] In a further variant of such a bundle according to the invention, an additional strip can be formed in each case between the two edge regions (the later second carrier elements) and the central region (the later first carrier element) of the carrier strand, which strip forms an outer wall when the packaging unit is completely folded together. In such an embodiment, a certain basic distance between the first and second carrier elements is provided, which is advantageous especially in the case of thicker goods units.
[0141] The edge regions 22, 22′ can also be designed to be substantially wider than shown, so that after folding over the second carrier elements 22, 22′ the front side of the packaging unit is closed.
[0142] It is also possible to deposit a second web, for example a transparent film, on the goods units 3 before the second carrier elements 22, 22′ are folded over, so that the finished packaging unit is also completely closed at the front. This second web does not have to be connected to the carrier strand 11, since it is held in a form-fitting manner when the bundle is dimensioned appropriately.
[0143]
[0144] Alternatively, the band can also be designed to be continuous on the front side, above the goods unit 3, in such a case the two ends of the band strip being folded around the carrier strand 11 and fastened on the carrier strand 11 on the remote rear side.
[0145] The carrier strand 11 can also be designed narrower than the goods unit 3, as shown by way of example in the variant in
[0146] Another variant of a bundle 1 according to the invention, having a two-layer configuration of the packaging units 2, is explained with reference to
[0147] At four connection points 27 per packaging unit 2, 2′, 2″, 2′″, the first carrier element 21 and the second carrier element 22 are connected to a carrier strand 11 so that the goods units 3 are fixed in a sandwich-like and form-fitting manner between the two carrier elements 21, 22. A perforation line is attached as a hinge element 17 and predetermined breaking point 18 between adjacent packaging units 2′, 2′, 2″, 2′″ in each case.
[0148] In the embodiment shown, a viewing window through which the goods unit 3 is visible is cutout in the second carrier element 22. This viewing window can alternatively also be omitted, or a transparent film can be arranged in the in the viewing window. This film can be fixed, for example, on the inside of the second carrier element 22. However, since the transparent film is fixed in a form-fitting manner within the packaging unit in the case of suitable dimensioning, it can also be placed only on the goods unit.
[0149] The two carrier elements 21, 22 are manufactured from a suitable material, for example paper, which is provided in a band-shaped manner.
[0150] An advantageous embodiment of a bundle 1 according to the invention is discussed on the basis of
[0151] In order to produce such a bundle 1, two tabs 25a, 25b are punched out of the carrier element 21 of each packaging unit 2 in the provided band-shaped carrier strand 11, along three sides of a rectangle in each case. After the placement of the goods unit 3, in the example shown a pair of socks 31, in an inner region between the two tabs 25a, 25b, the two tabs 25a, 25b of the band 25 are folded over towards the inner region, around the goods unit 3, and glued to a band 25. A second data element 23 is then also attached to the finished band 25. Again, perforation lines are attached, as predetermined breaking points 18 and/or hinge elements 17, between adjacent packaging units 2, 2′, 2″, 2′″.
[0152] Instead of creating the packaging units 2, 2′, 2″, 2′″ of a bundle 1 according to the invention from the carrier strand 1, as in the preceding examples, the packaging units can also be produced separately and then attached to the carrier strand 11 in order to thereby create a bundle 1 according to the invention. For example,
[0153] Said packaging units 2, 2′, 2″, 2′″ are configured as packages in which the goods units (not visible) are arranged.
[0154] Such bundles according to the invention are particularly advantageous for packaging units or goods units of limited size and weight, for example smaller domestic articles, cosmetics, electronic devices and data carriers, but also for example medicaments or replacement parts. For such goods, a bundle 1 according to the invention is advantageous due to the significantly lower technical effort of the automatic handling and the separation of the goods.
[0155] In order to create a bundle 1 according to the invention, the finished packaging units 2, 2′, 2″, 2′″, including contents, are advantageously fastened, for example glued or welded, to the carrier strand 11 provided as a continuous belt. The at least one corresponding connection point is not visible in the plan view of the figure.
[0156] Since the packaging units 2, 2′, 2″, 2′″ are already sufficiently mechanically stable, the carrier strand 11 can be designed to be flexible. In such a case, the entire portion of the flexible carrier strand 11 between two adjacent packaging units acts as a hinge element 17. In the example shown, a predetermined breaking point 18 is also assigned to the carrier strand 11 of each packaging unit 2. However, this can alternatively also be omitted. For example, for separating a single packaging unit, the relative narrow carrier strand 11 between two packaging units can be simply cut through.
[0157] Alternatively, it is also possible to release the connection between the carrier strand and packaging units in another manner, for example by conveying a packaging unit in a laterally supported manner, and at the same time pulling away the carrier strand downwards, so that the packaging unit is peeled off or torn off from the carrier strand. The carrier strand that is no longer required can then be used again or recycled.
[0158] Instead of as a mechanically stable object, the packaging units can also be designed as bags, for example.
[0159] Alternatively, or additionally, second data elements 23 can also be provided on the rear side of the carrier strand 11, as shown by way of example in
[0160]
[0161] The variant shown in the aforementioned figures, having functionally separate packaging units and carrier strand, can also be used for larger packaging units. In this case, without disadvantageous influence on the intended use, the carrier strand can be designed in a material-saving manner, in that the carrier strand is formed in two parts or in multiple parts.
[0162] Such a variant of a bundle 1 according to the invention is shown in
[0163] In the example shown, the packaging units 2, 2′ comprise a mechanically stable carrier element 21, on which a goods unit 3 in the form of a shirt 31 is reversibly fixed at four fastening points. Alternatively, the packaging units can also be designed as packages, bags or other closed containers.
[0164] The embodiment of a bundle 1 according to the invention shown in
[0165] In addition to the simplified conveying, bundles 1 according to the invention also have the advantage that they are efficiently stored in a transport container 19 for transport from the manufacturer to an intralogistics system, and can subsequently also be removed again in an automated manner for further use, which is explained with reference to
[0166] A bundle analogous to
[0167] The mass of the packaging units 2, the box 19 and the distances of the packaging units from one another on the carrier strand 11 are advantageously matched to one another in such a way that the highest possible packing density is achieved. Advantageously, the packaging units of one layer are each supported on the packaging units of the underlying layer.
[0168] Another embodiment of a bundle 1 according to the invention is shown in
[0169] Functionally independently of this variant of the fastening of the goods units 3 on the carrier elements 21 of the packaging units 2, the carrier strand 11 is provided on the outer edges with conveying active elements in the form of punched strips 14. Corresponding conveying means, for example in the form of needle wheels, can come into operative connection with these punched strips, in order to ensure precise and reliable conveying of the bundle 1 along the longitudinal direction 10.
[0170] Yet another variant of a bundle 1 according to the invention can be seen in
[0171] In order to be able to minimize the material thickness of the carrier strand 11 and nevertheless achieve the necessary mechanical stiffness of the carrier element 21, stiffening elements 29 are arranged on the outer edges of the carrier elements 21. These are produced in that a corresponding lateral portion of the carrier strand 11 (shown in dashed lines) is provided with adhesive and rolled up from the outside towards the inside, to form a thin but rigid tube 29.
[0172] Alternatively, such a stiffening element can also have a triangular or square cross section. Instead of an adhesive connection, form-fitting fixations can also be provided, such as, for example tuck-in tab connections.
[0173]
[0174] A first data element 12 in the form of a one-dimensional barcode is arranged on the start element 15. This first data element 12 is logically assigned to the entire bundle and can, for example, contain information on the length of the bundle, the type and number of packaging units, the goods units contained therein, their position with respect to the carrier strand, etc. It is also possible to provide data therein that allow a processing device to adapt to the specific bundle and adjust the machine settings and process parameters accordingly. In this way, it is possible to realize a processing device, such as a device 6 according to the invention for inserting goods units into a transport container, such that it can process more than one type of bundles 1 according to the invention. In this case, the correct adjustment can take place automatically so that different kinds and types of bundles 1 according to the invention can be processed as far as possible without manual changeover work and with minimal idle times.
[0175] A termination element 16 can be provided analogously at a second end 113 of a bundle 1 according to the invention, as shown in
[0176] An advantageous embodiment of a device 6 according to the invention for inserting goods units 3 into a transport container 8 is shown schematically in
[0177] A provided bundle 1 according to the invention in a transport container 19 according to
[0178] The provided bundle 1 according to the invention is guided via a deflecting roller 611 of a feed module 61 of the device 6 according to the invention onto a horizontal conveying device 613 of the mentioned feed module in the form of a belt conveyor 612. In this case, the propulsion of the bundle strand takes place via drive means (not shown). An identification module of the device 6 is equipped to read out the data element 23 of each packaging unit 2 at an identification position 659 using a camera 653. Advantageously, the identity of the packaging unit 2 can be compared with the read-out data element 23 and verified, on the basis of the acquired image. A separation module 62 is provided to separate a packaging unit 2′ from the bundle 1 by severing the carrier strand 11 at the predetermined breaking point.
[0179] The separated packaging unit is conveyed to an insertion module 63 of the device 6, for example by means of a belt conveyor or, driven by gravity, —on a chute 631. In the case of the insertion module 63, the packaging unit 2″ reaches a conveying device 631, for example a chute, which allows the packaging unit to slide into an opening of a transport container 8, in the present example into an overhead conveyor bag 81 of an overhead conveyor system 91.
[0180] The overhead conveyor bag 81 is transferred from a closed state (not shown) into an open filling state by a provision module 64 of the device according to the invention. One possible example of a suitable provision module of this kind is disclosed, for example, in US 2019/0367282 A1.
[0181] While an empty overhead conveyor bag 81, already in the orientation provided for filling, is conveyed in a suspended manner on a carriage 82 guided in a running rail 911, the base of the overhead conveyor bag is lifted by a sequence of roller-like actuators 642, as a result of which the suspended conveyor bag is opened. A lateral stop element 641 stabilizes the suspended conveyor bag horizontally, transversely to the conveying direction of the overhead conveyor system. The overhead conveyor bag is stopped and fixed with respect to the running rail 911 by means of a stop element 643. The overhead conveyor bag is now in the filling state. The packaging unit 2″ separated from the bundle 1 according to the invention can be inserted into the suspended conveyor bag 81. After the filling, the stop element 643 releases the overhead conveyor bag 81 again. The filled overhead conveyor bag 81 is conveyed further in the overhead conveyor system 91, and the next empty overhead conveyor bag is brought up for filling.
[0182] A device 6 according to the invention is advantageously integrated into a conveyor system 9, in particular a conveyor system of an intralogistics system 7, as shown by way of example as a diagram in
[0183] A further advantageous embodiment of a device 6 according to the invention for inserting goods units 3 into a transport container 8 is shown schematically in
[0184] The bundle 1 provided is guided, via a deflecting roller 611 of a feed module 61 of the device 6, onto a horizontal conveying device 613 of the feed module 61 in the form of a belt conveyor 612. A separation module 62, which is provided to separate a packaging unit 2′ from the bundle 1, by severing the carrier strand 11 at the predetermined breaking point, is arranged between the deflecting roller 611 and the belt conveyor 612. The packaging element 2′ thus isolated and lying on the belt conveyor 612 is then conveyed further. An identification module 65 of the device 6 reads the data element 23 of the packaging unit 2′ using a camera 653. Advantageously, the identity of the packaging unit 2 can in turn be compared with the read-out data element 23 and verified, on the basis of the acquired image.
[0185] The separated packaging unit is conveyed to an insertion module 63 of the device 6, for example by means of a belt conveyor or, driven by gravity, —on a chute 631. In the insertion module 63, the packaging unit 2″ reaches a conveying device 631, for example a chute, which allows the packaging unit to slide into an opening of a transport container 8, in the present example into a conveying tray 81 of a tilt tray conveyor 95.
[0186] In the case of such tilt tray conveyor systems 95 known from the prior art, conveyor trays 85 which can be tilted transversely to the conveying direction on one or two sides are mounted on carriages 86, which are guided in a rolling manner in a running rail 951. The carriages 86 which are uniformly spaced apart from one another are coupled to a revolving chain drive (not shown) and move with constant velocity.
[0187] Alternatively or in addition, a stopper element can be provided at the end of chute 631, for example in the form of a pivotable flap at the end of the chute 631, which can swing up. In the swung-up state, the flap can retain a packaging unit on the chute. When a conveying tray of the tilt tray conveyor is located below the chute, the flap swings down, and the retained packaging unit drops into the conveying tray.
[0188] In the devices 6 discussed above, the feed module 61 can have one or more horizontal conveyor units arranged in series before and/or after the belt conveyor 612, which can be actuated selectively. In this way, an advantageous buffer storage can be realized, which facilitates synchronization of the provision of the packaging units and the overhead conveyor bags.
