Technical Field

[0001] This invention relates to a track arrangement structure for a suspended conveyor for transporting suspended goods in a sorting system. The track arrangement structure includes a travel structure that includes or forms a current supply section and a travel surface for the self-propelled transport. Furthermore, this invention relates to a modular track system for constructing such a track arrangement structure. Additionally, this invention relates to a suspended conveyor for transporting suspended goods in a sorting system, comprising a track arrangement structure of the type described above and multiple self-propelled transports traveling on or within it. Finally, this invention relates to a sorting system having a storage area for storing goods, a sorting area for sorting goods according to orders, and a suspended conveyor of the type described above connecting the storage area and the sorting area. Background Technology

[0002] The aforementioned types of track layout structures, modular track systems, overhead conveyor equipment, and sorting systems are known in principle. Here, a self-propelled transport vehicle travels on the track layout structure to transport suspended goods in this manner. Suspended goods can be formed either by goods transported in suspended bags or by goods directly suspended from the suspended goods carrier. The latter should be understood in particular as clothing on hooks, but these garments can also be additionally surrounded by suspended bags for better protection. Constructing such a track layout structure is sometimes difficult, and correspondingly, modifications or expansions can only be achieved at considerable expense. Summary of the Invention

[0003] Therefore, one objective of this invention is to provide improved track layout structures, improved modular track systems, improved overhead conveyor equipment, and improved sorting systems. In particular, the construction, modification, and expansion of the track layout structures, overhead conveyor equipment, or sorting systems should be made easier.

[0004] The objective of this invention is achieved by a track arrangement structure of the type described at the beginning, the track arrangement structure comprising:

[0005] (First) A running structure, said running structure including or forming a current supply section and a running surface for a self-propelled transport vehicle, and

[0006] (First) A carrying track, wherein the traveling structure is directly or indirectly fastened to the carrying track.

[0007] Furthermore, the objective of this invention is achieved through a modular track system (a modular track system or "parts kit" for manufacturing track layout structures) for a suspended conveyor for transporting suspended goods in a sorting system, the modular track system comprising:

[0008] At least one running structure, said running structure including or forming a current supply section and a running surface for a self-propelled transport vehicle, and

[0009] At least one carrying track, wherein the at least one traveling structure is directly or indirectly fastened to the carrying track.

[0010] In addition, the object of the present invention is achieved by a suspended conveyor for transporting suspended goods in a sorting system, the suspended conveyor comprising a track arrangement structure of the type described above and a plurality of self-propelled transport vehicles traveling on or in thereon.

[0011] Finally, the objective of the present invention is achieved by a sorting system of the type described at the beginning, in which a suspended conveyor connecting the storage area and the sorting area is configured as described above.

[0012] The proposed measures, particularly the modular approach, significantly simplify the construction, modification, and expansion of track layouts, overhead conveyors, or sorting systems. This requires only a small number of different, combinable components, making the manufacturing and warehousing of these components easier and less costly.

[0013] Track-mounted structures or overhead conveyor systems can be used not only for transporting suspended goods, but also for sorting and / or buffering or storing goods. Especially in conjunction with sorting systems, this allows for the design of advantageous cargo flows.

[0014] The self-propelled transport vehicle is electrically driven and, in particular, has a current collector that draws electrical energy from a current supply unit in the running gear. The current supply unit of the running gear may have multiple sliding surfaces that are insulated from each other, having different voltage potentials during operation of the track arrangement, and the current collector of the transport vehicle slides on these sliding surfaces. The wheels of the transport vehicle are driven by an electric motor, and the wheels roll on the running surfaces. The transport vehicle may have one (single) wheel axle or multiple wheel axles.

[0015] Other advantageous designs and further extensions of the invention are derived from the dependent claims and from the description taken in conjunction with the accompanying drawings.

[0016] Preferably, the track arrangement structure of the overhead conveyor for the self-propelled transport vehicle (the overhead conveyor is used to transport suspended goods in the sorting system) may include:

[0017] (First) The bearing track has a groove on the underside, extending in the longitudinal direction of the bearing track, and particularly configured as a dovetail or T-shape.

[0018] (First) A carrier element, which is inserted into the slot, and

[0019] (First) A running structure, comprising or forming a current supply section and a running surface for a self-propelled transport vehicle, and the running structure being secured directly or indirectly to the carrying rail by the carrying element. The use of the slots particularly simplifies construction, modification, and expansion. Thus, the assembly of the running structure can be easily carried out from below, where scaffolding is not necessarily required.

[0020] Preferably, the modular track system may include:

[0021] At least one support rail has a groove extending in the longitudinal direction of the support rail and, in particular, configured as a dovetail or T-shape, said groove being arranged on the underside in the assembled state of the support rail.

[0022] At least one support element, which can be hooked into the slot, and

[0023] At least one running structure, the running structure including or forming a current supply section and a running surface for a self-propelled transport vehicle, and the running structure being able to be secured directly or indirectly to the carrying track by the carrying element.

[0024] Advantageously, if the (first) driving structure includes:

[0025] Viewed in the longitudinal direction of the load-bearing track, the (first) retaining clip, which is annular, U-shaped, or H-shaped, is fastened to the load-bearing track.

[0026] A current track, supported internally within the retaining clamp and oriented in the longitudinal direction of the carrying track, includes a current supply section for a self-propelled transport vehicle or forms such a current supply section.

[0027] A travel track, spaced apart below the current track and supported inside the retaining clamp and oriented in the longitudinal direction of the carrying track, the travel track comprising or forming a travel surface for the self-propelled transport vehicle.

[0028] Accordingly, only a very small number of different components are needed to construct such a track layout.

[0029] Preferably, the current track and the travel track are held by two retaining clips arranged in the end regions. In principle, more than two retaining clips may also be used for each current track and travel track. Due to the proposed measures, the current track and travel track preferably do not require (direct) connections to the load-bearing track or to the load-bearing element. Furthermore, the vertical spacing between the current track and the travel track is also preferably achieved by one or more retaining clips. It is generally advantageous that the retaining clips are made of plastic. Thus, the retaining clips can be manufactured economically. It is also advantageous that the two travel tracks extend parallel to each other in pairs, spaced laterally apart, forming a travel track arrangement structure. This creates a gap between the two travel tracks through which the load-bearing structure of the self-propelled transport vehicle can protrude.

[0030] Preferably, the retaining clip can be secured to the (first) bearing rail by means of the (first) bearing element. This allows for a particularly simple and flexible securing of the retaining clip to the bearing rail.

[0031] What is particularly advantageous is that

[0032] The groove, particularly the groove of the (first) bearing track, is configured in a dovetail shape, and

[0033] The load-bearing element is configured as a two-piece unit and includes two load-bearing plates bent at obtuse angles. The load-bearing plates are folded together at one of their legs to form a Y-shaped load-bearing element, wherein the folded legs are vertically oriented in the assembled state, and the inclined extended legs are located in the inclined load-bearing surface of the dovetail-shaped groove of the load-bearing track.

[0034] Therefore, the support element for the dovetail-shaped groove can be manufactured using simple means, as only two metal strips need to be bent. The support element is created through the arrangement of the plates, ensuring it cannot slide out of the groove and is self-centered. Assembly of the support element is also extremely simple. In a first step, a first support plate is hung into the groove; in another step, a second support plate is hung into the groove, at another longitudinal position on the support track, and then the two support plates are pushed together, forming a Y-shaped support element. No tools are required for this. In other words, the assembly of the support element can be performed without tools.

[0035] It is also particularly advantageous that the grooves, especially the grooves of the (first) bearing track, have protrusions at the outer ends of the inclined bearing surface, which work together with the bearing plate to prevent the bearing plate from tipping over. Thus, the bearing plate will not fall out of the groove even when it is not supported by the second bearing plate, thereby further simplifying the assembly of the bearing element.

[0036] Furthermore, it is advantageous that

[0037] The support plate has recesses at its folded legs, the recesses being arranged flush with each other, and

[0038] The first travel structure or retaining clip is connected to the load-bearing element by means of bolts or screws guided through the recess.

[0039] Thus, the first travel structure or retaining clip can be fastened to the load-bearing element using simple technical means. In particular, when bolts are used, the travel structure can be fastened to the load-bearing element without tools. The connection between the load-bearing element and the first travel structure or retaining clip is here "indirect." However, the connection can also be made "directly" (i.e., without using additional components, such as bolts or screws).

[0040] Preferably, the (first) travel structure includes a bottom groove extending particularly in the longitudinal direction of the (first) support rail, with fastening devices arranged on the (first) support rail. The fastening devices are capable of being embedded in the groove of the (first) travel structure, and the (first) travel structure is secured to the (first) support rail by means of the fastening devices. The arrangement of the groove on the first travel structure allows for particularly rapid fastening and replacement of the travel structure from below.

[0041] Preferably, the fastening device can be a screw, particularly a hammerhead screw. Preferably, the fastening device can include a nut. Specifically, when configured as a hammerhead screw, the hammer-shaped head end of the hammerhead screw can be inserted into the groove of the (first) traveling structure, and the threaded section of the hammerhead screw can be guided through and protrude from a hole in the bearing rail, wherein, preferably, the hammerhead screw is held on the bearing rail by means of a nut. Through the hammer-shaped head end of the hammerhead screw, the (first) traveling structure and the undercut groove can be coupled or decoupled from the (first) bearing rail particularly easily, by simply rotating the hammerhead screw such that the hammer-shaped head end is engaged in the groove.

[0042] Preferably, the bottom groove of the (first) travel structure extends in the longitudinal direction of the (first) support rail, especially when the (first) travel structure is fastened to the support rail.

[0043] Preferably, the bottom groove of the (first) travel structure, especially when the (first) travel structure is fastened to the bearing rail, can extend laterally to the longitudinal direction of the (first) bearing rail.

[0044] Preferably, the fastening device includes an adjusting device, wherein a preset distance between the (first) bearing rail and the (first) traveling structure, particularly the (first) retaining clamp, can be adjusted by means of the adjusting device. This allows for particularly simple and quick leveling or planar orientation of the first traveling structure, particularly the retaining clamp. Consequently, drive energy can be saved during the operation of the suspended conveyor by avoiding unnecessary height differences, particularly by the passage of the traveling surface.

[0045] Preferably, the adjusting device can be a threaded section of a screw, particularly a hammerhead screw. Preferably, the preset distance between the (first) bearing rail and the (first) traveling structure can be adjusted by means of a nut, particularly the position of the nut on the threaded section. Preferably, any other adjusting device suitable for adjusting the distance between the (first) bearing rail and the (first) traveling structure, such as racks and pinions or rod-like components and clamping devices, can also be used.

[0046] Preferably, the undercut groove of the (first) traveling structure, particularly extending in the longitudinal direction, is formed on the (first) retaining clip. This allows for particularly simple and quick replacement of the (first) retaining clip by simply loosening the fastening device and removing the (first) retaining clip. The laborious process of pulling the (first) retaining clip out of the guide rail is eliminated. Consequently, production costs can also be reduced compared to carriers with continuous grooves.

[0047] Preferably, the bottom groove of the (first) traveling structure can be arranged on the (first) retaining clip, on the upper side of the (first) retaining clip. The upper side is preferably the side facing the (first) bearing rail when the (first) retaining clip is fastened to the (first) bearing rail.

[0048] Furthermore, it is advantageous that the current track and / or the travel track are supported in the retaining clip without the need for screws. In other words, the current track and / or travel track are simply placed or pushed into the retaining clip, thereby simplifying the assembly of the travel structure.

[0049] Another advantage is that the load-bearing track, the current track, and / or the travel track are configured as hollow profiles. This makes the components relatively lightweight, allowing for easy assembly while also preventing the application of excessively high gravity to the load-bearing structure.

[0050] Preferably, the track layout structure may include a (first) turnout or crossing module, which is coupled to a first travel structure and has multiple travel tracks extending in different directions. Thus, the self-propelled transport vehicle can change its direction or travel track.

[0051] For example, the first turnout or crossing module may include a connecting flange, a travel platform, a current supply platform, and a gap holder.

[0052] The driving platform is arranged at intervals below the current supply platform and is connected to the current supply platform via connecting flanges and spacers.

[0053] The driving platform is coupled to the driving track of the driving structure, and the current supply platform is coupled to the current track of the driving structure.

[0054] The driving trajectories extending in different directions are arranged in the driving platform and the current supply platform.

[0055] As a result, the characteristics of the running structure in the area of ​​the first turnout or crossing module are continued, so that the self-propelled transport vehicle can seamlessly switch from the running structure to the turnout or crossing module and switch back.

[0056] Specifically, it can be specified that the driving platform includes an internal driving platform and an external driving platform, wherein the internal driving platform is connected to the current supply platform via a spacer and the external driving platform is connected to the current supply platform via a connecting flange. Thus, a gap can be provided between the internal and external driving platforms, through which the load-bearing structure of the self-propelled transport vehicle can extend. The current supply platform can also be configured as a single piece, thereby making it particularly easy to manufacture.

[0057] The first turnout or crossing module can preferably be directly or indirectly, particularly through a first or second load-bearing element, fastened to the load-bearing rail. Thus, the gravity caused by the first turnout or crossing module can be directly transferred to the load-bearing rail.

[0058] In particular, the first turnout or crossing module may have a second retaining clip, in which the travel platform and current supply platform are supported. The second retaining clip is fastened to the carrier rail by means of a first or second carrier element, or the second retaining clip includes an undercut groove extending particularly in the longitudinal direction of the first carrier rail. Additional fastening devices are arranged on the first carrier rail, which can be embedded in the groove of the second retaining clip, and the second retaining clip is fastened to the first carrier rail by means of these additional fastening devices. Thus, three possibilities for fastening the second retaining clip can be easily formed. Therefore, the retaining clip achieves multiple uses and is not only used in the manufacture of travel structures but also for retaining turnouts or crossing modules.

[0059] Preferably, the additional fastening device can be configured in the same manner as the fastening device.

[0060] When the slot in the bearing track is configured as a dovetail or T-shape, the second bearing element in the above-described embodiment of the turnout or cross module can be configured as a two-piece structure, comprising two bearing plates bent at obtuse angles. The bearing plates are folded together at one leg to form a Y-shaped bearing element, wherein the folded leg is vertically oriented in the assembled state, and the inclined extended leg is located in the inclined bearing surface of the dovetail slot.

[0061] Preferably, the first retaining clip and the second retaining clip can be connected to each other, particularly screwed together in the longitudinal direction of the bearing track. This results in a particularly stable track arrangement structure.

[0062] A spacer and / or end members for the running track may also be provided between the first and second retaining clips. The end members are particularly useful for facilitating the insertion of the transport vehicle into the running track arrangement structure when it exits the area of ​​the turnout or crossing module. The end members may have corresponding entry ramps for this purpose.

[0063] Preferably, the track arrangement structure may include a second load-bearing track extending parallel to the first load-bearing track at a lateral spacing, wherein the width extension dimension of the first turnout or crossing module perpendicular to the longitudinal direction of the load-bearing track is equal to this lateral spacing. This allows the travel trajectory extending perpendicular to the first and second travel structures to be formed only through the turnout or crossing modules. The lateral spacing is measured here from the middle of the first load-bearing track to the middle of the second load-bearing track or from the middle of the first travel structure to the middle of the second travel structure.

[0064] Another advantage is that the width extension dimension of the first turnout or crossing module with respect to its longitudinal direction perpendicular to the carrying track is centered relative to the carrying track. This results in a symmetrical construction of the track arrangement structure.

[0065] Another advantage is that the first turnout or crossing module is rotationally symmetrical about its vertical axis with a rotation angle of 90°. This further enhances the symmetry of the track layout structure and allows for more flexible use of the first turnout or crossing module.

[0066] Also advantageously, the track arrangement structure includes a second turnout or crossing module, which is coupled to the first turnout or crossing module and has multiple travel tracks extending in different directions. Thus, more complex configurations of the travel tracks or paths for self-propelled transport vehicles are possible.

[0067] In particular, the second turnout or crossing module may have all or some of the aforementioned features of the first turnout or crossing module. In other words, the two turnout or crossing modules may be constructed identically or at least similar to each other.

[0068] Preferably, a second travel structure may be provided, wherein a second turnout or crossing module is coupled to the second travel structure, wherein the two turnout or crossing modules have or form a travel trajectory extending laterally to the first and second travel structures.

[0069] Preferably, it can be specified that the travel trajectory extending laterally to the first and second travel structures is formed only through turnouts or intersection modules.

[0070] Preferably, the second turnout or crossing module may include a connecting flange, a travel platform, a current supply platform, and a gap holder.

[0071] The driving platform is arranged at intervals below the current supply platform and is connected to the current supply platform via connecting flanges and spacers.

[0072] The driving platform is coupled to the driving track of the second driving structure, and the current supply platform is coupled to the current track of the second driving structure.

[0073] The driving trajectories extending in different directions are arranged in the driving platform and the current supply platform.

[0074] Preferably, the current supply platform of the second turnout or crossing module can be coupled to the current supply platform of the first turnout or crossing module, and the travel platform of the second turnout or crossing module can be coupled to the travel platform of the first turnout or crossing module. It is also conceivable that the current supply platform of the second turnout or crossing module is coupled to the current track of the second travel structure, and the travel platform of the second turnout or crossing module is coupled to the travel track of the second travel structure. Thus, complex construction of the track layout structure is also possible.

[0075] The disclosed arrangement is not limited to two running structures and two turnout or crossing modules. It is also possible that the disclosed arrangement is recursively repeated transversely to the first and second running structures. Here, the second running structure replaces the position of the first running structure, and another running structure replaces the position of the second running structure. Furthermore, the second turnout or crossing module replaces the position of the first turnout or crossing module, and another turnout or crossing module replaces the position of the second turnout or crossing module. More than two turnout or crossing modules can also be arranged (directly) sequentially in the longitudinal direction of the carrying track. This results in a matrix arrangement of turnout or crossing modules that can be directly connected to each other (i.e., without running structures located in between).

[0076] Furthermore, it is advantageous that the connecting flanges of the first and second turnout or crossing modules are connected to each other, particularly screwed together. This results in a stable construction of a combination of multiple turnout or crossing modules.

[0077] Furthermore, it is advantageous that the connecting flanges have form-locking elements that work together to orient the connecting flanges relative to each other. For example, the form-locking elements can be configured as grooves and tenons, holes and pins, inner and outer tapers, or plug connectors, and achieve orientation of the connecting flanges relative to each other in the horizontal and / or vertical directions.

[0078] The most likely scenario is:

[0079] The connecting flanges of the first and second turnouts or crossing modules are not securely fastened to the load-bearing rails, or

[0080] At least one of the first and second turnout or crossing modules has a second retaining clip arranged adjacent to the connecting flange, and the travel platform and the current supply platform are supported in the second retaining clip.

[0081] The second retaining clip is fastened to the bearing rail by means of the first bearing element or by means of the second bearing element, or

[0082] The second retaining clip includes a bottom groove extending particularly in the longitudinal direction of the first bearing track, wherein (an additional) fastening device is arranged on the (first) bearing track, wherein the (additional) fastening device can be embedded in the groove of the second retaining clip, and the second retaining clip is fastened to the (first) bearing track by means of the (additional) fastening device.

[0083] When the connecting flanges of the first and second turnouts or crossing modules are not fastened to the load-bearing rails, the connection between the two turnouts or crossing modules is self-supporting, thus simplifying the construction of the track layout structure. When a second retaining clamp is provided, the force acting at the connection point of the turnout or crossing module is transferred to the load-bearing rail, resulting in a particularly stable track layout structure.

[0084] Preferably, in the track arrangement structure, multiple vertical columns and horizontally extending beams can be provided, the beams being connected to the columns, wherein the load-bearing track lies flat on the beams and extends perpendicularly to them. This results in a relatively simple construction of the track arrangement structure. In particular, it avoids the costly assembly on the ceiling.

[0085] Advantageously, the vertical column has a recess into which the bearing claws of the crossbeam are embedded. This allows for tool-free construction of the load-bearing structure. Particularly advantageously, the recess is configured as an elongated slit extending obliquely from above towards the middle of the column. Consequently, the crossbeam is pulled towards the column by the gravity acting upon it, thereby ensuring or improving the stability of the arrangement.

[0086] Preferably, the spacing between the two crossbeams is chosen such that it allows for:

[0087] Driving structure,

[0088] Current tracks and travel tracks,

[0089] At least one turnout or crossing module is combined with the running structure or with the current track and the running track, or

[0090] Combination of turnout or crossing modules only

[0091] Crossover.

[0092] Therefore, the load-bearing structure formed by columns and beams can be used for the complex construction of track layout structures.

[0093] Furthermore, it is advantageous that the vertical columns are tensioned diagonally using tension cables. This improves the stability of the track layout structure. The intersecting tension cables can form either a horizontal or vertical plane.

[0094] Modular track systems can in particular have one or more of the components described above and listed below:

[0095] Ring-shaped, U-shaped, or H-shaped retaining clips,

[0096] Current track,

[0097] travel track,

[0098] Load-bearing tracks with dovetail or T-shaped grooves,

[0099] Two-piece Y-shaped load-bearing element,

[0100] Turnout or crossing module,

[0101] Spacer

[0102] End components for use on running tracks

[0103] Connecting flange,

[0104] beam,

[0105] Carrying claw.

[0106] Therefore, only a small number of different types of components are needed to construct the track layout structure.

[0107] In suspended conveyor systems, it is particularly advantageous that the clearance between the current track and the travel track is greater than the maximum longitudinal extension dimension of the transport vehicle measured along the longitudinal direction of the carrying track. This makes it possible for the transport vehicle to be laterally pulled out of the track arrangement structure around its wheel axis after rotating 90° from its operating position.

[0108] In summary, the running gear can be coupled to each other, turnout or crossing modules can be coupled to each other, and the running gear and turnout or crossing modules can be coupled to each other. The term "coupled" in the given context specifically means arranging the components side-by-side so that a transport vehicle can travel on them. Direct connection between the components is feasible but not necessary. In principle, it is sufficient for the components to be flush with each other and fastened to the load-bearing rails.

[0125] First, it should be noted that in different described embodiments, the same components are provided with the same reference numerals or the same component names. The disclosure contained throughout this specification can be meaningfully applied to the same components having the same reference numerals or the same component names. Location descriptions selected in the specification, such as above, below, side, etc., also refer to the direct description and the accompanying drawings, and these location descriptions are meaningfully applied to the new location when the location changes.

[0126] Figure 1 and 2 At least a plurality of portions of the exemplary suspended conveyor 1 are shown in oblique views. Figure 1 An overview of the overhead conveyor 1 is shown. Figure 2 The suspended conveyor is shown in detail.

[0127] The suspended conveyor 1 preferably includes a plurality of vertical columns 2 and horizontal beams 3 extending therebetween, the beams being connected to the columns 2. Track arrangement structure 5 (in...) Figure 3 and 4 The load-bearing track 4 (shown in detail) is preferably supported on the crossbeam 3 and extends perpendicular to the crossbeam. In addition to the track arrangement structure 5, the overhead conveyor 1 also includes a self-propelled transport vehicle 6 that transports the suspended cargo 7. Furthermore, the overhead conveyor 1 or the track arrangement structure 5 includes multiple optional cross modules 8, in which the transport vehicle 6 can select one of multiple travel tracks.

[0128] Preferably, the vertical column 2 is tensioned diagonally using optional tension cables 9a and 9b to improve the stability of the suspended conveyor 1. The intersecting tension cables 9a and 9b can form a horizontal plane, but it is also conceivable that two intersecting tension cables 9a and 9b form a vertical plane. This is in... Figure 1 As exemplarily shown in the figure.

[0129] Figure 3 Show Figure 1 and 2 The suspended conveyor 1 has a reduced number of parts to improve clarity. Figure 4 Show Figure 3 The details are further magnified. Specifically, Figure 3 Two vertical columns 2 and 2' are shown, each having a horizontally extending beam 3 between them and a support rail 4 resting flat on the beam 3. In fact, the support rail 4 is also resting flat on... Figure 3 On the second crossbeam 3 (not shown).

[0130] Preferably, the crossbeam 3 is fastened to the columns 2 and 2' by means of bearing claws 10 and 10'. This is in Figure 3 The following is illustrated exemplarily. Preferably, the bearing claws 10, 10' are embedded in the recesses C of the vertical columns 2, 2'. The recesses C are preferably configured as elongated slits that extend obliquely from above towards the middle of the respective columns 2, 2'. Thus, the crossbeam 3 is pulled toward the columns 2, 2' by the gravity acting upon it, thereby ensuring or improving the stability of the arrangement.

[0131] The track arrangement structure 5 preferably includes a load-bearing track 4, a load-bearing element 11, and a (first) running structure 12. This is in Figure 3 and 4 As exemplarily shown in the figure.

[0132] The support rail 4 preferably has a groove A extending longitudinally on its lower side, into which the support element 11 is inserted. The lower side of the support rail 4 is preferably the underside of the support rail 4, which faces the ground when the support rail 4 is in its assembled state.

[0133] The running structure 12 is preferably indirectly fastened to the carrying rail 4 via the carrying element 11, and forms the current supply part 13 and the running surface B for the self-propelled transport carrier 6. However, the running structure 12 may also be directly fastened to the carrying rail 4 (i.e. without the carrying element 11).

[0134] Preferably, the track arrangement structure 5 includes an H-shaped retaining clip 14 viewed in the longitudinal direction of the carrying track 4.

[0135] Preferably, the H-shaped retaining clip 14 can be secured to the carrying rail 4 by means of the carrying element 11. This is in Figure 4 As exemplarily shown, wherein, for better illustrative purposes, the carrier element 11 is in Figure 4 The image shows the support element 11 outside the support track 4. In reality, the support element 11 is preferably located at the height of the retaining clip 14 when assembled.

[0136] The track arrangement structure 5 preferably includes a current track 15 supported on the inside of the retaining clamp 14 and oriented in the longitudinal direction of the carrying track 4. The current track is used to include or form the current supply section 13 of the self-propelled transport vehicle 6.

[0137] Preferably, the track arrangement structure 5 includes two travel tracks 16a, 16b that are spaced apart below the current track 15, supported on the inside in the retaining clamp 14, and oriented in the longitudinal direction of the carrying track 4, the travel tracks forming or including a travel surface B for the self-propelled transport vehicle 6.

[0138] The two travel tracks 16a and 16b are preferably arranged in pairs to form a travel track arrangement structure 17. This is in Figure 4 and 14 As exemplarily shown, the transport carrier 6 extends through the gap present in the middle. In the region of the crossbeam 3, an optional retaining clip arrangement 18 is provided in this example, which will be described in detail later.

[0139] Preferably, the retaining clip 14 has an H-shaped basic structure. However, it is also conceivable that the retaining clip 14, when viewed in the longitudinal direction of the carrying track 4, is configured as an annular or U-shaped structure. The H-shaped retaining clip 14 in Figure 4 As exemplarily shown in the diagram. The U-shaped retaining clip 14 is in... Figure 14 As exemplarily shown in the figure.

[0140] The retaining clip 14 is preferably made of plastic.

[0141] The groove A extending in the bearing track 4 can be configured as, for example, dovetail or T-shaped. Advantageously, the groove A is configured as a dovetail, and the bearing element 11 is configured as a Y-shaped and supported or hung in the groove A, as in... Figure 3 and 4 The situation is shown in the example.

[0142] Preferably, the support element 11 can be configured as a two-piece unit and includes two support plates 19a and 19b bent at obtuse angles, the support plates 19a and 19b being folded together at one leg to form a Y-shaped support element 11. This is in Figure 4As exemplarily shown in the figure. The folded legs are preferably oriented vertically in the assembled state, and the inclined extended legs are located in the inclined bearing surface D of the dovetail groove A of the bearing track 4.

[0143] Preferably, groove A has protrusions G at the outer ends of the inclined bearing surface D. These protrusions work together with the bearing plates 19a and 19b to prevent them from tipping over. This ensures that no single bearing plate 19a or 19b will fall out of groove A, even when only one of the bearing plates 19a or 19b is placed in groove A. Consequently, the assembly of the bearing plates 19a and 19b is significantly simplified.

[0144] The support plates 19a and 19b preferably have recesses E at their folded legs, the recesses being arranged flush with each other. The running structure 12 or retaining clip 14 is preferably connected to the support element 11 by means of bolts or screws 20, the bolts or screws being guided through holes F and recesses E in the retaining clip 14. This in Figure 4 As exemplarily shown in the figure.

[0145] The current track 15 and / or the travel tracks 16a, 16b are preferably supported without screws in the retaining clip 14. This is in Figure 4 and Figure 14 As exemplarily shown in the diagram, the assembly of the track arrangement structure 5 can thus be performed with particularly high efficiency.

[0146] The connection between the load-bearing element 11 and the running structure 12 or the retaining clip 14 is Figure 4 The example shown is performed "indirectly." However, the connection can also be made "directly" (i.e., without using additional components, such as bolts or screws 20).

[0147] The load-bearing track 4, the current track 15, and the travel tracks 16a and 16b are preferably constructed as hollow profiles. As a result, the track arrangement structure 5 is relatively lightweight, and the vertical columns 2 and 2' and the crossbeams 3 do not need to be designed to be overly robust.

[0148] The self-propelled transport vehicle 6 is preferably electrically driven and, in particular, has a current collector that can draw electrical energy from the current supply unit 13 of the traveling structure 12. Preferably, the current collector can slide on a current track 15, which may have multiple sliding surfaces insulated from each other, the sliding surfaces having different voltage potentials during operation of the track arrangement structure 5. The current track 15... Figure 4 and 14 As exemplarily shown in the figure.

[0149] The acquired electrical energy is preferably directed to an electric motor (neither shown in the figures) via control electronics, which drives the wheels of the transport vehicle 6. In this example, the wheels rolling on the travel surface B or on the travel tracks 17a, 17b are arranged on a single axle. Between the travel tracks 17a, 17b, a support structure for the self-propelled transport vehicle 6 extends through, onto which a suspended bag 7 or other suspended carrier can be mounted. The disclosed track arrangement structure 5 is not limited to the transport vehicle 6 specifically shown, but other structural types of transport vehicles 6, such as those with more than one wheel axle, can also be used.

[0150] Particularly advantageous is that the clearance h between the current track 15 and the travel tracks 16a, 16b is greater than the maximum longitudinal extension dimension l of the transport vehicle 6 measured along the longitudinal direction of the carrying track 4. This makes it possible for the transport vehicle 6 to be pulled laterally out of the track arrangement structure 5 around its wheel axis after rotating 90° (from the operating position shown in the figure). Preferably, the diameter of the wheel substantially corresponds to the longitudinal extension dimension l of the transport vehicle 6.

[0151] Figure 5 Show Figure 1 and 2 The suspended conveyor 1 has another part with a reduced number of parts, and Figure 6 Showing a slightly different perspective from Figure 5 Furthermore, the local area is magnified. Specifically, in Figure 5 and 6 In the middle, two traveling structures 12a and 12b are supported on the crossbeam 3, and these two traveling structures extend parallel to each other with a lateral distance q between them. Furthermore, Figure 5 and 6 The illustrated arrangement includes four turnout or crossing modules 8a...8d, wherein the first turnout or crossing module 8a is coupled to the first travel structure 12a, and the second turnout or crossing module 8b is coupled to the second travel structure 12b. The coupling is achieved here via retaining clip arrangements 18a, 18b. Two additional retaining clip arrangements 18c, 18d are provided in the region of the crossbeam 3 for coupling the turnout or crossing modules 8c, 8d.

[0152] the following Figure 7 A preferred embodiment of the retaining clip arrangement structure 18 is shown in an enlarged illustration viewed from a side angle. Figure 8 An exploded view of a preferred embodiment of the retaining clip arrangement structure 18 is shown. Furthermore, Figure 9 and 10 The turnout or crossing module 8 is shown in an isolated diagram. Figure 9 Shown from the upper diagonal, Figure 10 Shown from the lower diagonal.

[0153] The turnout or crossing modules 8, 8a...8d preferably include connecting flanges 21, 21a, 21b, a travel platform 25, a current supply platform 28, and a gap holder 29, respectively.

[0154] The travel platform 25 is preferably arranged at a distance below the current supply platform 28 and is connected to it via connecting flanges 21, 21a, 21b and spacer 29.

[0155] Preferably, the travel platform 25 includes an internal travel platform 26 and an external travel platform 27, wherein the internal travel platform 26 is preferably connected to the current supply platform 28 via a spacer 29 and the external travel platform 27 is connected to the current supply platform 28 via connecting flanges 21, 21a, and 21b. The travel platform 25 is preferably coupled to travel tracks 16a and 16b, and the current supply platform 28 is coupled to current tracks 15, 15a, and 15b.

[0156] The turnout or crossing modules 8, 8a...8d preferably each have multiple travel tracks H1, H2 extending in different directions. Preferably, the travel tracks H1, H2 can be arranged in the travel platform 25 and the current supply platform 28. This is in... Figure 9 and 10 As can be seen by example, the current supply platform 28 can be configured as a single piece.

[0157] Preferably, the turnout or crossing modules 8, 8a...8d have four coupling possibilities and travel trajectories H1, H2 that intersect each other at right angles. This is in Figure 9 and 10 The example shown is not the only conceivable approach. It is conceivable that another number of coupling possibilities exist, giving another intersection angle to the travel trajectories H1, H2. Furthermore, the coupling possibilities can deviate from rotational angular symmetry and, in particular, be oriented parallel to each other. In this case, in particular, the transport vehicle 6 can switch directly from the first travel structure 2a to the adjacent parallel-extending second travel structure 12b.

[0158] These two turnout or crossing modules 8a, 8b are preferably coupled not only to the running structures 12a, 12b, but also to each other through connecting flanges 21a, 21b forming the flange arrangement structure 22. This is in Figure 5 and 6The following is exemplarily shown. These two turnout or crossing modules 8a, 8b are thus preferably formed to form a travel trajectory H1 extending perpendicularly to the first and second travel structures 12, 12a, 12b. Specifically, the travel platform 25 of the second turnout or crossing module 8b is connected to the travel platform 25 of the first turnout or crossing module 8a, and the current supply platform 28 of the second turnout or crossing module 8b is connected to the current supply platform 28 of the first turnout or crossing module 8a.

[0159] The connecting flanges 21, 21a, and 21b preferably have form-locking elements that orient the connecting flanges 21, 21a, and 21b relative to each other. For example, the form-locking elements can be configured as grooves and tenons, holes and pins, inner and outer cones, or plug connectors, and orient the connecting flanges 21, 21a, and 21b relative to each other in the horizontal and / or vertical directions. The connecting flanges 21a and 21b of the first and second turnout or cross modules 8a and 8b are preferably not fastened to the load-bearing rail 4. That is, the connection between the two turnout or cross modules 8a and 8b is preferably self-supporting. However, it is also conceivable that the connecting flanges 21a and 21b are connected to the load-bearing rail 4, for example, through the load-bearing element 11.

[0160] The width extension dimension b of the turnout or crossing modules 8, 8a...8d, measured perpendicular to the longitudinal direction of the carrying rail 4, is preferably equal to the lateral spacing q between the parallel extending travel structures 12a, 12b, particularly the lateral spacing q between their carrying rails 4. The lateral spacing q is measured here from the middle of the first carrying rail to the middle of the second carrying rail 4, or by the travel structures 12a, 12b. By the proposed measure, the travel trajectory H1 extending perpendicular to the first and second travel structures 12a, 12b is formed only by the turnout or crossing modules 8a, 8b. Relatedly, it is also advantageous (but not necessary) that the turnout or crossing modules 8, 8a...8d are centered relative to the carrying rail 4 with respect to their width extension dimension b, as in... Figure 5 and 6 The situation is shown in the example.

[0161] The turnout or crossing modules 8, 8a...8d are advantageously rotationally symmetric about the corresponding vertical axis about a rotation angle of 90°, as in... Figures 5 to 11 As exemplarily shown in the diagram. Thus, turnout or crossing modules 8, 8a...8d can be used with particular flexibility.

[0162] The first turnout or crossing module 8a and the second turnout or crossing module 8b are preferably constructed identically. This is advantageous because only a relatively small number of different components are needed to construct the track layout structure 5, but in principle, it is also conceivable to use turnout or crossing modules 8a and 8b with different configurations.

[0163] exist Figure 7 and 8 The preferred embodiment of coupling the turnout or crossing module 8 to the running gear 12 by means of the retaining clip arrangement structure 18 is now shown. Figure 8 The retaining clip arrangement is shown in an exploded view. In this example, the turnout or crossing module 8 includes a preferred embodiment of a second retaining clip 14b, in which the travel platform 25 and the current supply platform 28 are supported. The second retaining clip 14b is preferably secured to the carrier rail 4 by means of a carrier element 11. For example, a second separate carrier element 11 can be used for this purpose, which can be... Figure 4 The configuration is shown. It is also conceivable that the carrier element 11 is configured as... Figure 4 The second retaining clip 14b, shown as longer, spans the distance between the two retaining clips 14a and 14b and also has another recess E. The second retaining clip 14b can then be connected to the bearing element 11 by means of another bolt or screw 20, which is guided through the additional recess E. In both cases, the turnout or crossing module 8 is indirectly fastened to the bearing rail 4 via the bearing element 11. However, it is also conceivable in principle that the turnout or crossing module 8 is directly fastened to the bearing rail 4 (i.e., without using the bearing element 11). Furthermore, the turnout or crossing module 8 can also be fastened to the bearing rail 4 by means of retaining clips 14, 14a, and 14b, which include undercut grooves extending particularly in the longitudinal direction of the bearing rail 4. Such retaining clips 14, 14a, and 14b in… Figure 13 and 14 As exemplarily shown in the figure.

[0164] It is also conceivable that the first retaining clip 14a and the second retaining clip 14b are connected to each other. In particular, these retaining clips can be screwed together in the longitudinal direction of the carrying rail 4. Spacers 23a, 23b and / or end members 24 for the travel rails 16a, 16b can also be provided between the first retaining clip 14a and the second retaining clip 14b, as in... Figure 7 and 8 As exemplarily shown, the end member 24 is specifically designed to facilitate easier insertion into the track arrangement structure 17 when the transport vehicle exits the area of ​​the turnout or cross module 8. The end member 24 has a corresponding introductory ramp for this purpose.

[0165] However, connecting the turnout or crossing modules 8a, 8b via connecting flanges 21a, 21b and via retaining clip arrangement 18 is not the only conceivable method of connection. It is also conceivable that the turnout or crossing module 8 has a second retaining clip 14, arranged adjacent to the connecting flange 21a, and that the travel platform 25 and the current supply platform 28 are supported within the second retaining clip. This is in... Figure 9 and 10 As exemplarily shown in the figure.

[0166] The first retaining clip 14a and the first connecting flange 21a of the first turnout or crossing module 8a, and the second retaining clip 14b and the second connecting flange 21b of the second turnout or crossing module 8b, preferably form flange clamp arrangement structures 30 respectively, and preferably can together form a double flange clamp arrangement structure 31, as shown in... Figure 11 The double flange clamp arrangement 31 is preferably configured similarly to the retaining clamp arrangement 18, but the difference is that instead of spacers 23a, 23b and end members 24, two connecting flanges 21a, 21b are arranged between the retaining clamps 14a, 14b.

[0167] The retaining clips 14a and 14b are preferably secured indirectly to the carrying rail 4 via the carrying element 11 or directly (i.e., without using the carrying element 11) to the carrying rail 4. For the two retaining clips 14a and 14b, preferably two separate carrying elements 11 or a common, longer carrying element 11 can be provided. The first retaining clip 14a and the second retaining clip 14b can also preferably be connected to each other, for example, screwed together in the longitudinal direction of the carrying rail 4. The description of the retaining clip arrangement structure 18 is applicable herein in a meaningful sense.

[0168] Figures 5 to 11 The arrangement shown is not limited to two running structures 12a, 12b and two turnout or crossing modules 8a, 8b. It is also possible that the disclosed arrangement is recursively repeated transversely to the first and second running structures 12a, 12b. Here, the second running structure 12b replaces the position of the first running structure 12a, and another running structure 12 replaces the position of the second running structure 12b. Furthermore, the second turnout or crossing module 8b replaces the position of the first turnout or crossing module 8a, and another turnout or crossing module 8 replaces the position of the second turnout or crossing module 8b. More than two turnout or crossing modules 8a, 8b can also be arranged (directly) sequentially in the longitudinal direction of the carrying track 4. This results in a matrix arrangement of turnout or crossing modules 8a, 8b, which can be directly connected to each other (i.e., without running structures 12, 12a, 12b located between them).

[0169] Typically, the spacing between the two crossbeams 3 can be achieved through...

[0170] A driving structure 12, 12a,

[0171] One current track 15, 15a, 15b and one travel track 16a, 16b

[0172] At least one turnout or crossing module 8, 8a...8d combined with a running structure 12, 12a or with a current track 15, 15a, 15b and a running track 16a, 16b, or

[0173] Combinations of turnout or crossover modules 8, 8a...8d only

[0174] To bridge the gap.

[0175] The track arrangement structure 5 or the suspended conveyor 1 can be constructed using a modular track system, which includes at least a load-bearing track 4, a load-bearing element 11, and running structures 12, 12a, and 12b. In particular, the modular track system may have one or more of the following components:

[0176] Ring-shaped, U-shaped, or H-shaped retaining clips 14, 14a, 14b

[0177] Current tracks 15, 15a, and 15b

[0178] Running tracks 16a and 16b

[0186] 3. Crossbeam

[0187] Bearing claws 10 and 10'.

[0188] Figure 12 An exemplary sorting system 32 is illustrated schematically and in a highly simplified manner. The sorting system 32 includes a storage area 33 for storing goods, a sorting area 34 for sorting goods according to orders, and a suspended conveyor 1 of the disclosed type connecting the storage area 33 and the sorting area 34. The suspended conveyor 1 can be used to transport suspended goods 7, but can also be used to sort and / or buffer or store suspended goods 7.

[0189] The track arrangement structure 5 is specified to include first travel structures 12 and 12a and a first load-bearing track 4. The first travel structures 12 and 12a are directly or indirectly fastened to the first load-bearing track 4.

[0190] Preferably, the first traveling structures 12, 12a may include undercut grooves K extending particularly in the longitudinal direction of the first bearing rail 4, and fastening devices 40 are arranged on the first bearing rail 4, wherein the fastening devices 40 can be embedded in the grooves K of the first traveling structures 12, 12a, and the first traveling structures 12, 12a are fastened to the first bearing rail 4 by means of the fastening devices 40. This is in Figure 13 and 14 This is illustrated exemplarily. Here, Figure 13 The preferred embodiment of the track arrangement structure 5 and the preferred embodiment of the retaining clips 14, 14a, 14b are shown from an obliquely upward view. Figure 14 The track arrangement structure 5 is shown in an end view. Figure 13 The preferred embodiment shown is illustrated.

[0191] Preferably, the fastening device 40, particularly the additional fastening device for the second retaining clip 14b of the turnout or cross module 8, 8a…8d, can be a screw, particularly a hammerhead screw. Preferably, the fastening device 40, particularly the additional fastening device, can include a nut. Specifically, when configured as a hammerhead screw, the hammer-shaped head end of the hammerhead screw can be inserted into the groove K of the first travel structure 12, 12a, 12b, and the threaded section of the hammerhead screw can be guided through and protrude from a hole in the bearing rail, thereby preferably holding the hammerhead screw on the bearing rail 4 by means of a nut. Through the hammer-shaped head end of the hammerhead screw, the first travel structure 12, 12a, 12b and the undercut groove can be coupled or decoupled from the first bearing rail 4 particularly easily, by simply rotating the hammerhead screw so that the hammer-shaped head end is locked in the groove K. This in… Figure 13 and 14 As exemplarily shown, in which, Figure 14 The diagram shows the hammer-shaped head of the hammerhead screw being inserted into the slot K. Furthermore, in... Figure 14 The nut used for fixing is shown in the figure.

[0192] Particularly preferably, the fastening device 40 may include an adjusting device 41, wherein a preset distance between the first bearing track 4 and the first traveling structures 12, 12a, particularly the (first) retaining clips 14, 14a, 14b, can be adjusted by means of the adjusting device 41. Figure 14 As can be seen by example.

[0193] Preferably, the adjusting device 41 can be a threaded section of a screw, particularly a hammerhead screw. This is in Figure 14This is illustrated exemplarily. Preferably, the preset distance between the (first) bearing rail 4 and the (first) traveling structures 12, 12a, 12b, and especially the (first) retaining clips 14, 14a, 14b, can be adjusted by means of the position of the nut, particularly the nut on the threaded section. Figure 14 In this configuration, the (first) support rail 4 is exemplarily located on the retaining clips 14, 14a, and 14b. Here, an adjustment device 41 configured as a threaded section is visible above the nut, wherein the distance between the retaining clips 14, 14a, and 14b and the support rail 4 can be adjusted by loosening the screw.

[0194] Preferably, any other adjusting device suitable for adjusting the distance between the (first) bearing rail and the (first) travel structure, such as racks and pinions or rod-shaped components and clamping devices, may also be used.

[0195] Preferably, it can be specified that the undercut groove K of the first traveling structure 12, 12a, particularly extending in the longitudinal direction, is formed on the (first) retaining clip 14, 14a. This is in Figure 14 As can be seen exemplarily. For example... Figure 13 and 14 It can be seen that the groove K extends in the longitudinal direction of the first bearing rail 4 while keeping the clamps 14, 14a, and 14b fastened on the bearing rail 4.

[0196] Preferably, the undercut groove K extending longitudinally on the retaining clips 14, 14a, 14b is continuously formed from the first end face of the retaining clips 14, 14a, 14b to the second end face opposite to the first end face and spaced apart from the first end face. The first end face of the retaining clips 14, 14a, 14b is... Figure 14 As exemplarily shown in the figure.

[0197] The retaining clips 14, 14a, 14b are preferably devices for securing the current supply section 13, particularly the current rails 15, 15a, 15b, and / or for securing the travel rails 16a, 16b, particularly the travel surface B, and / or for securing the (first) turnout or crossing modules 8, 8a...8d to the (first) bearing rail 4.

[0198] Preferably, the current tracks 15, 15a, 15b and / or the travel tracks 16a, 16b can be supported without screws in the first retaining clips 14, 14a. Screwless support is preferably achieved by clamping the current tracks 15, 15a, 15b and / or the travel tracks 16a, 16b in the retaining clips 14, 14a, 14b. This is in Figure 4 and 14 As exemplarily shown in the figure.

[0199] The retaining clips 14, 14a, 14b are preferably adapted to simply fasten the (first) turnout or crossing modules 8, 8a…8d to the (first) load-bearing rail 4. The retaining clips 14, 14a, 14b here may be configured in the same manner as the retaining clips 14, 14a, 14b used to fasten the (first) running structures 12, 12a to the (first) load-bearing rail 4, and also include the same fastening devices, which may also be referred to as other fastening devices.

[0202] Preferably, the bottom groove K can also extend laterally to the longitudinal direction of the first bearing track 4.

[0203] Preferably, the bottom groove K of the (first) traveling structures 12, 12a can be arranged on the (first) retaining clips 14, 14a, 14b, on the upper side of the (first) retaining clips 14, 14a, 14b. The upper side is preferably the side facing the (first) bearing rail 4 when the (first) retaining clips 14, 14a, 14b are fastened to the (first) bearing rail 4. This is in Figure 13 and 14 As exemplarily shown in the figure.

Various features or combinations of features from the different embodiments shown and described can, in themselves, present independent inventive solutions. The task upon which these independent inventive solutions are based can be derived from the specification.
