CONVEYOR VEHICLE, IN PARTICULAR SELF-EXECUTIVE SHUTTLE, FOR A SHELTER

The invention relates to a conveyor vehicle, in particular a self-propelled shuttle, for loading and unloading of goods in or from a storage rack of a rack storage, which is movable along rails in front of the storage rack, comprising a base frame of a plurality of frame parts, a plurality of wheels and a load receiving device for loading and unloading of goods in and out of the storage rack of the rack storage.

It is already a transfer shuttle for loading and unloading of goods in or out of a storage rack of a rack warehouse from US 2011/0008138 A1 become known. This has a base frame in solid construction, on which the drive device, the wheels and the load bearing device are constructed. The disadvantage here is the high weight or mass of the base frame, which must be constantly moved with the driving movements.

DE 201 12 328 U1, DE 203 07 005 U1, DE 10 2008 022 322 A1, DE 20 2007 003 447 U1, EP 1 422 169 A2, US 2009/0074545 A1 and WO 2010/017871 A1 disclose different embodiments of transport vehicles for the transport of goods, wherein the transport vehicle comprises a composite of several individual frame parts base frame, a plurality of wheels and a load receiving device. Are all wheels driven, the wheels are either each coupled to a drive member (electric motor) or pairs of impellers each to a drive member (electric motor).

In the transport vehicles disclosed in DE 203 07 005 U1, DE 10 2008 022 322 A1 and DE 20 2007 003 447 U1 are so-called satellite vehicles, which are moved into a storage channel to a load (pallet) in to store the storage channel or to outsource it from the storage channel. The load-carrying device is designed as a hoist.

The present invention has for its object to provide a conveyor vehicle with a base frame, wherein the frame parts to form the base frame can be easily and inexpensively manufactured with a high weight saving and beyond a reliable operation is possible.

This object of the invention is achieved in that the base frame, a first assembly, which is spaced apart from each other in the vertical direction with respect to a direction of travel and opposing first wheels, and a second assembly, which between the in the vertical direction with respect to a Direction of travel distanced from each other and opposing second wheels is arranged, and the first and second module connecting and extending in the direction of Ers-th / second wheels in the direction of travel extending, in particular hollow profile-shaped frame parts, wherein the first assembly in the region of the first wheels in each case one formed console-shaped frame subassembly and the console-shaped frame subassemblies connecting transversely to the direction of Längsprofilförmig formed frame member, and the second assembly in the region of the second wheels in each case a konsol Enframe formed frame subassembly and the console-shaped frame subassemblies transverse to the direction connecting longitudinally shaped frame part comprise, and that a plurality of frame parts are each material fit joined to the frame subassemblies and the frame subassemblies are each non-positively and / or positively connected to one of the other frame parts, wherein the frame parts of Base frame formed from sheet metal, cut-to-size cut components and / or formed of sheet metal formed non-cutting formed parts.

The advantage here is that the majority of the frame parts made of thin sheet metal without cutting in the form of simple, mostly planar components and / or formed from sheet metal forming formed. The frame parts can be produced at low cost, and this can be done especially in a simple series production in small batches. The consumption of material for the production of such frame parts is low. The shaping, starting from the planar metal sheet, is usually carried out by means of a blank, which is carried out, for example, with a sheet metal shears, shearing shears, a water jet cut, a thermal separation process (flame cutting, laser cutting). But it is also possible for larger series, that the cutting is done by a punching process. The thin sheet material allows almost unlimited designs. Furthermore, non-cutting shaping methods, in particular methods for the cold forming of sheets, such as bending, pressing, embossing or the like, can be used. The deformation of the sheet takes place in an accuracy that can be realized within narrow position and shape tolerances. Machining can usually be omitted. Thus, a simple and inexpensive composable modular system can be created. As a result of this special connection choice of individual frame parts to frame subassemblies by means of integral connection, a degree of prefabrication can already be achieved in which the welding distortion can also be kept relatively low. However, the further connections are made by means of non-positive and / or positive connection means, whereby after a simple alignment a distortion-free connection can be done with each other. In this way, as well as from the frame parts or frame subassemblies own assemblies can be formed, which can be easily connected to other frame parts. The base frame can also be formed from a plurality of prefabricated frame subassemblies, which are connected to each other by means of non-positive and / or positive connection means. But this can also be done with the interposition of their own frame parts. Thus, the subsequent straightening effort of the base frame can be greatly minimized or even avoided.

Furthermore, but also faster adjustment movements of the entire conveyor vehicle can be achieved so that the storage and retrieval operations can be performed in less time. This further increases the productivity of the entire storage system.

Also advantageous is the formation of individual modules, as already a certain prefabrication of individual components can be done and a rapid completion of the entire conveyor vehicle is possible. In addition, high strength or inherent stiffness of the base frame can be achieved despite the low intrinsic mass of the individual frame parts used. By using individual frame parts in different shapes a modular system can be implemented.

It is also advantageous if the first and second assembly each additionally comprise a extending between the bracket-shaped frame subassemblies and hollow profile-shaped frame part, which additionally connects the console-shaped frame subassemblies together. As a result, an additional stiffening of the assembly is achieved.

It is also possible according to an embodiment of the invention that in each case a bearing arrangement for the impeller is arranged on the console-shaped frame subassemblies.

It is also advantageous if the respectively in the region of the wheels extending in the direction of travel frame parts are interconnected by X-shaped frame parts, as an additional torsional rigidity of the entire base frame between the oppositely arranged wheels is created. In addition, so sufficient space for the arrangement of drive and recording organs is created, whereby the entire structure of the conveyor vehicle can be further simplified.

In one embodiment of the invention, the X-shaped frame members are formed by a single component, wherein the frame parts are arranged to each other in a plane, so that with minimal space requirement, a sufficient stiffening of the outside extending frame parts of the base frame can be achieved.

It is also advantageous if at least two wheels arranged one behind the other in the direction of travel on a first side of the base frame via a traction means of a traction drive are in drive connection, in addition those wheels on the other side of the base frame via a respective drive shaft with the wheels on the first side of the base frame are in drive connection and further the traction means is in driving connection with a drive member. Thus, the entire dynamics of the movements, in particular the acceleration and the deceleration, can be significantly improved in both drive directions. Thus, starting from all driven wheels, no matter which direction of movement, regardless of the load and the weight distribution, always achieves optimum transmission of the drive torque towards the rails. In addition, however, achieved by the drive of all wheels an exact linear movement of the conveyor vehicle during its adjustment movements. In order for a precise positioning driving or starting the individual acquisition or dispensing positions is achieved, whereby an even higher density in the rack warehouse can be achieved. Furthermore, in conjunction with the simply constructed base frame, an additional reduction of the own weight or the net mass of the conveyor vehicle can be achieved. Thus, the small number of components also simplifies the entire design.

By choosing the cohesive joint connection is achieved so that waives additional connection means and thus the weight or the mass of the base frame can be further reduced. However, if non-positive and / or positive connection means used, a draft-free assembly is achieved and can also be done even a simple exchange of individual frame parts. This is particularly advantageous for damage and maintenance.

Furthermore, the invention also relates to a conveyor vehicle, in particular a self-propelled shuttle, for loading and unloading of goods in or from a storage rack of a rack storage, which is movable along rails in front of the storage rack, comprising a base frame of a plurality of frame parts, a plurality of wheels and a load receiving device for loading and unloading of goods in and out of the storage rack of the rack storage and an electrical control device, wherein the load receiving device manipulation units and a drive unit, and wherein the base frame, the wheels, the drive unit for the load receiving device and the electrical control device form a base frame.

In hitherto known self-propelled conveyor vehicles, a separate base frame or support frame was produced in dependence on the manipulation unit used for the cargo handling the load receiving device, to which then the manipulation unit has been attached. The disadvantage here was that for each type had its own support frame or base had to be made, which brought an increased amount of design activity, manufacturing and assembly with it. In addition, stockpiling was always problematic because it was not exactly clear in advance which type of transport vehicle was needed in the respective warehouse.

Therefore, a further object of the invention is to provide a base or support frame for a particular self-propelled conveyor vehicle, which is universally applicable to different types of lifting equipment.

This object of the invention is achieved in that the base frame is prefabricated for replacing differently trained load-receiving devices and is formed independently of the load-carrying device to be attached, wherein the base frame at least a first mechanical interface part and / or at least a first electrical interface part is provided and the Manipulation units of the load receiving device each having at least a second mechanical interface part and / or at least a second electrical interface part and the first and second interface parts each form a mechanical interface and / or an electrical interface.

It is advantageous that by the provision of predefined interfaces on

Base frame, in particular the base frame a high degree of prefabrication in a plurality of identical parts can be achieved. Thus, regardless of the later to be mounted load receiving device, a single base or base frame can be created, which can be manufactured in large quantities and preassembled so far that only the load-carrying means or the load-carrying device is to be attached to the designated interfaces. By providing further electrical interfaces, it is also possible to reduce wiring occurring during final assembly to the extent that this is limited to connecting electrical interface parts to the electrical interface provided for this purpose.

It is also advantageous if the majority of the frame parts of the conveyor vehicle are formed from thin sheets without cutting in the form of simple, mostly planar components and / or formed from sheet metal forming parts, as described above. The frame parts can be produced at low cost, and this can be done especially in a simple series production in small batches. The consumption of material for the production of such frame parts is low. The shaping, starting from the planar metal sheet, is usually carried out by means of a blank, which is carried out, for example, with a sheet metal shears, shearing shears, a water jet cut, a thermal separation process (flame cutting, laser cutting). This creates a high number of identical components, which can be assembled in the form of a modular system to form a single base frame. At this the interfaces are provided for connection with the manipulation devices, so as to provide also a simple, predefined connection possibility.

The invention also relates to a conveyor vehicle, in particular a self-propelled shuttle, for loading and unloading of goods in or from a storage rack of a racking, which is movable along rails in front of the storage rack, comprising a base frame of a plurality of frame parts, a plurality Impellers and a load-carrying device for loading and unloading of goods in or out of the storage rack of the shelf storage.

DE 203 07 005 U1, DE 10 2008 022 322 A1 and DE 20 2007 003 447 U1 disclose conveyor vehicles for the transport of goods in which all the wheels are driven, in which case the wheels are either each to a drive member (electric motor) or Impeller pairs are each coupled to a drive member (electric motor).

Therefore, another object of the invention to provide a conveyor vehicle, which can be operated dynamically.

This object of the invention is achieved in that the frame parts of the base frame formed from sheet metal, cut-to-size components and / or formed from non-cutting metal formed sheet metal parts, wherein frame parts are joined cohesively to at least one frame subassembly and these at least one frame subassembly Kraft- and / or positively connected to at least one further frame part and / or at least one further frame part of another frame subassembly and that at least two in a direction consecutively arranged impellers are on a first side of the base frame via a traction means of a traction drive in drive connection, in addition those Impellers are on the other side of the base frame via a respective drive shaft with the wheels on the first side of the base frame in drive connection and further the traction means is in driving connection with a drive member. As a result, the entire dynamics of the travel movements, in particular the acceleration as well as the deceleration, can be substantially improved in both drive directions. Thus, starting from all driven wheels, no matter which direction of movement, regardless of the load and the weight distribution, always achieves optimum transmission of the drive torque towards the rails. In addition, however, achieved by the drive of all wheels an exact linear movement of the conveyor vehicle during its adjustment movements. This achieves a positionally accurate activation or starting of the individual transfer or delivery positions, as a result of which an even higher control density can be achieved in the slider. Furthermore, in conjunction with the simply constructed base frame, an additional reduction of the own weight or the net mass of the conveyor vehicle can be achieved. Thus, the small number of components also simplifies the entire design.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Introductoryly it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or identical component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or the same component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

1 to 3, a possible embodiment of a shelf storage system 1 is shown, which may include a rack storage 2 for a variety of goods 3, at least one self-propelled conveyor vehicle 4 and optionally a load-lifting device 5 and a Förderfahrzeug- lifting device 6.

The shelf storage 2 has at a distance preferably parallel to each other arranged storage racks 7a, 7b, between which extends a rack aisle 8, starting from a first shelf storage page 9 to a second shelf storage page 10 and which in each other superimposed shelves 11 each side provided parking spaces 12th form for the goods 3. According to the embodiment shown, the storage racks 7a, 7b in the racking levels 11 each side by side and also provided successively parking spaces 12 for the load 3, so in the depth direction of the storage racks 7a, 7b two loads 3 can be turned off, therefore a so-called "double-deep" storage is possible. On the other hand, it is also possible that the storage racks 7a, 7b in the racking levels 11 each form only in a row next to each other provided parking spaces 12 for the goods 3, so in Tiefenrich direction of the storage racks 7a, 7b only a load 3 can be turned off, therefore a so-called "single-deep" storage is possible.

As can be seen from FIG. 1, the shelf storage system 1 on the first shelf support side 9 can additionally comprise a buffer zone which in each case has the shelving levels 11 of the storage shelves 7a, 7b in a row of buffer locations 13a, 13b for at least one load 3 , The buffer locations 13a, 13b are each formed on a drivable conveyor track, for example a transport device, such as accumulation roller track, accumulation belt conveyor and the like, whose conveying direction runs parallel to the rack aisle 8.

In each shelf level 11 extends along the aisle 8 from the first shelf storage site 9 to the second shelf storage site 10, a first guideway along which the conveyor vehicle 4 (shuttle) is guided movable to goods 3, such as containers, cardboard, trays or the like. To transport to the shelves 11 of the storage racks 7a, 7b each provided for slots 12 and transported away from the 12 provided in the racking levels 11 of the storage racks 7a, 7b respectively designated slots 12.

The first guideways in the shelf levels 11 are each formed by attached to the storage racks 7a, 7b horizontal rails 14a, 14b, each with a height guide track 15 and a side guide track 16.

If the buffer locations 13a, 13b are provided in front of each storage rack 7a, 7b on both sides of the rack aisle 8, second guideways are also provided in the first front zone of the rack storage 2 in each rack level 11 immediately in the extension of the first guideways in the rack warehouse 2 so that the conveyor vehicle 4 (shuttle) is also guided between the, at the level of the shelf levels 11 opposing buffer locations 13a, 13b guided to load 3 to the shelves in the shelves 11 of the storage racks 7a, 7b respectively provided buffer locations 13a, 13b and from the in the racking levels 11 of the storage racks 7a, 7b respectively provided buffer locations 13a, 13b to be transported away.

The second guideways in the shelf levels 11 are each formed by attached to the transport devices in the buffer zone horizontal rails 17a, 17b, each with a height guide track 18 and a respective side guideway 19.

The rails 14a, 14b; 17a, 17b are for example U-profiles, C-profiles or the like. The conveying vehicle 4, as shown in simplified form in FIG. 3, comprises a plurality of running wheels 20 and can be moved in a rolling motion along the height guide tracks 15, 18, individual ones of the running wheels 20 being designed as drive wheels. For lateral guidance of the conveyor vehicle 4, this is provided with side guide members 21. For example, the side guide members 21 are formed by formed on a housing part 22 of the conveyor vehicle 4 parallel guide stop surfaces, which between the side guide tracks 16, 19 of the rails 14a, 14b; 17a, 17b are positionable.

The conveyor vehicle 4 is further equipped with a load-receiving device 46 for storage and / or removal and / or rearrangement of one or simultaneously two or more goods 3. In the present embodiment, telescopic arms 47 and respective drivers 48 are provided for this purpose. Such a load-bearing device 46 is known, for example, from US 2005/0095095 A1 or EP 0 647 575 A1, and can advantageously be used due to the compact construction of the telescopic arms 47 and the reliable mode of operation.

On the first shelf support side 9, the load-lifting device 5 can be arranged frontally in front of the rack warehouse 2, which according to the embodiment shown independently raised and lowered receiving devices 23a, 23b for piece goods 3 has.

The receiving devices 23 a, 23 b each comprise a transport device 24 a, 24 b with a parallel to the rack aisle 8 extending conveying direction, wherein the first transport device 24 a on a first lifting drive 25 a vertically adjustable lifting frame 26 a and a second transport device 24 b on a via a second lifting drive 25b vertically adjustable lifting frame 26b are constructed.

According to the embodiment shown, the first transport device 24a is mounted on the lifting frame 26a on a first mast 27a and the second transport device 24b is mounted on the lifting frame 26b on a second mast 27b. The mast 27a, 27b is provided with guides 28a, 28b, on which the lifting frames 26a, 26b rest with guide wheels 29a, 29b in a rollable manner.

The transport devices 24a, 24b are thus independently (decoupled) from each other between the shelf levels 11 and the height level of each shelf level 11 adjustable, so that loads 3, such as containers, cardboard, trays or the like, between the transport devices 24a, 24b and Buffer places 13 a, 13 b can be promoted. Preferably, the transport devices 24a, 24b are each formed by an antreibba-re conveyor track, such as a accumulation roller conveyor, Staugurtförderer and the like. It also proves to be advantageous if the transport devices 24a, 24b can receive a plurality of goods 3, preferably up to four goods 3, one behind the other in the conveying direction.

One or more goods 3 can be transported by the transport device 24a, 24b to a single buffer space 13a, 13b in the shelf level 11 defined by a controller. Loading goods 3 can also be transported by the transport device 24a, 24b to a plurality of buffer locations 13a, 13b in different rack levels 11 defined by a controller. The transport devices 24a, 24b form a separating device according to this embodiment.

On the other hand, the load 3 can be picked up by the transport device 24a, 24b of a single buffer space 13a, 13b, then the transport device 24a, 24b initially adjusted to the level defined by a controller level of a shelf level 11 and then one or more goods. 3 be transported from the buffer space 13 a, 13 b in the rack level 11 on the transport device 24 a, 24 b. The transport devices of the buffer locations 13a, 13b forms a separating device according to this embodiment.

The goods 3 can be picked up by the transport device 24a, 24b of buffer locations 13a, 13b in different shelf levels 11. The transport device 24a, 24b is initially adjusted to the first height level of a shelf level 11 defined by a controller, and one or more loads 3 are transported from the buffer space 13a, 13b to the transport device 24a, 24b, and then the transport device 24a, 24b is transferred to that by a controller defined second height level of a shelf level 11 adjusted and transported one or more goods 3 from the buffer space 13a, 13b on the transport device 24a, 24b.

The transport devices 24a, 24b are thus independently (decoupled) adjustable from one another between the rack levels 11 to the height level of each rack level 11 and to the height level of a conveyor level 30, so that loads 3, such as containers, cardboard boxes, trays or the like, also can be conveyed between the transport devices 24a, 24b and a first Vorzonen conveyor.

The first pre-zone conveyor system connects to the load-lifting device 5 and comprises a first conveyor device 31a and a second conveyor device 31b, which run parallel to each other at a mutual distance. The conveying devices 31a, 31b are each formed by a driven conveying device, for example a roller conveyor, belt conveyor or the like. The first conveying device 31a extends in the extension of the first storage rack 7a and the second conveying device 31b extends in the extension of the second storage rack 7b, wherein the conveyor devices 31a, 31b of the first pre-zone conveyor and the conveying devices of the buffer zone at least by the length of the transport devices 24a, 24b are arranged spaced apart, so that the transport devices 24a, 24b are each movable in their lowered on the conveyor plane 30 transfer or transfer position between the mutually facing end edges of the conveying devices. Since the clear distance between the conveying devices 31a, 31b corresponds approximately to the width of the rack aisle 8, a very space-saving arrangement of the first pre-zone conveyor system is achieved.

Here are on the first conveyor 31a load 3 conveyed from the first Vorzonen conveyor to load-lifting device 5 and conveyed off via the second conveyor 31b cargo 3 from the load-lifting device 5 to the first Vorzonen conveyor.

On the second shelf support side 10 front of the rack storage 2, the Förderfahrzeug- lifting device 6 (transfer device) is arranged, which comprises a shown lifting and lowerable receiving device 35 for the conveyor vehicle 4.

The receiving device 35 comprises a guide track, which is constructed on a lift frame 36 via a vertically adjustable lifting frame 37. The guideway is mounted on the lifting frame 37 on a guide frame 38 which on vertical frame members 39a, 39b guides 40a, 40b, on which the lifting frame 37 rests with guide wheels 41a, 41b unrolled.

The guideway comprises parallel to the rack aisle 8 at a mutual distance horizontally extending rails 42a, 42b, which are mounted on the lifting frame 37 and each form a height guide track 49 and side guide track 50. The rails 42a, 42b are for example U-profiles, C-profiles or the like. The conveyor vehicle 4 can be moved on the wheels 20 along the height guide tracks 49 rolling. For lateral guidance of the conveyor vehicle 4 serve the above-described side guide members 21 which are positioned between the side guideways 50 of the rails 42a, 42b.

The conveying vehicle 4 (shuttle) can be implemented by the conveying vehicle lifting device 6 between the shelf levels 11 with load 3 or without load 3, such as containers, cardboard boxes, trays or the like.

The receiving device 35 or guide track can be adjusted between the shelf levels 11 to the height level of each shelf level 11 and the height level of a conveyor plane 43, so that load 3 can also be promoted between the receiving device 35 and a second Vorzonen conveyor.

The second pre-zone conveyor system connects to the hoisting vehicle lifting device 6 and comprises a first conveying device 44a and a second conveying device 44b, which run parallel to each other at a mutual distance. The stationary conveying devices 44a, 44b are each formed by a drivable conveying device, for example a roller conveyor, belt conveyor or the like. The first conveyor 44a extends in the extension of the first storage rack 7a and the second conveyor 44b extends in the extension of the second storage rack 7b. The clear distance between the conveying devices 44a, 44b arranged parallel to each other corresponds at least to the width of the receiving device 35, so that the receiving device 35 or guide track in their transfer position or transfer position lowered onto the conveyor plane 43 between the mutually facing longitudinal edges 45 of the conveying devices 44a, 44b are movable.

Since the clear distance between the conveying devices 44a, 44b corresponds approximately to the width of the rack aisle 8, a very space-saving arrangement of the second Vorzonen conveyor is achieved.

In this case, via the first conveyor 44a goods 3 are conveyed from the second Vorzonen- conveyor to the truck-lifting device 6 and conveyed off via the second conveyor 44b cargo 3 from the truck-lifting device 6 to the second Vorzonen conveyor.

By the conveyor vehicle lifting device 6, at least one conveyor vehicle 4 can now be implemented between the shelf level 11.

If now a load 3 within the rack warehouse 2, for example, for the purpose of storage compaction of a parking space 12 in the first shelf level 11 are transferred to a parking space 12 in the fourth shelf level 11, the conveyor vehicle 4 is initially taken on the receiving device 35 and adjusted by this to the height level defined by a controller of the first shelf level 11. Thereafter, the conveyor vehicle 4 moves along the guideways of the receiving device 35 in the rack warehouse 2 to the parking space 12 in the first shelf level 11. There arrived, by a schematically indicated in Fig. 3 load bearing device 46, the load 3 from the storage rack 7a, 7b outsourced and transferred to the conveyor vehicle 4. Thereafter, the conveyor vehicle 4 moves with the load 3 along the guideways from the rack warehouse 2 on the receiving device 35. If the conveyor vehicle 4 was taken over with the load 3 on the receiving device 35, the conveyor vehicle 4 is adjusted to the level defined by a controller level of the fourth shelf level 11 , Thereafter, the conveyor vehicle 4 moves along the guideways of the receiving device 35 in the rack storage 2 to the parking space 12 in the fourth shelf level 11 arrived there, the load 3 is stored by the load carrier 4 in the storage rack 7a, 7b by the load receiving device 46.

If, on the other hand, a load 3 is to be retrieved from the shelf storage 2 according to a picking order, the delivery vehicle 4 is initially adjusted by the receiving device 35 to the height level defined by a control of a shelf level 11. Thereafter, the conveyor vehicle 4 moves along the guideways of the receiving device 35 in the rack storage 2 to a parking space 12 in one of the shelf levels 11. There arrived, the load 3 is removed from the storage rack 7a, 7b by the load receiving device 46 and on the conveyor vehicle. 4 accepted. Thereafter, the conveyor vehicle 4 moves with the load 3 along the guideways from the rack storage 2 on the receiving device 35. If the conveyor vehicle 4 was taken over with the load 3 on the receiving device 35, the conveyor vehicle 4 is transferred to the defined by a control conveyor plane 43 in the transfer or transfer position between the conveying devices 44a, 44b moves and transfer the load 3 on the conveyor 44b. For the transfer of the load 3, in turn, the load-receiving device 46 or a (not shown) separate from the conveyor vehicle 4 unloading device, such as a slide or belt transfer can be used.

FIGS. 4 and 5 show a further embodiment of the conveyor vehicle 4, which may be independent of itself, in particular if this is designed as a so-called shuttle, wherein the same reference numerals and component designations as in the preceding FIGS. 1 to 3 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference. For better clarity, only those components of the conveyor vehicle 4 are shown in these figures, which relate to the supporting basic structure, in the present case a base frame 51, and a drive assembly 52. On the presentation of trim parts, the load receiving device 46 and actuating means for loading and unloading of the load 3 is omitted.

The base frame 51 of the conveyor vehicle 4 is here in a lightweight construction or a lightweight construction formed by sheet metal frame parts 53 to 58 or includes the base frame 51 this. In the present embodiment, these frame parts 53 to 58, the supporting structure of the base frame 51, which basically consist of components formed from sheet metal. Furthermore, even hollow profile-shaped components can be used, which have a high torsional and bending stiffness with sufficient strength properties. This can e.g. Form tubes or even formed from a sheet metal blank hollow body.

Furthermore, it is noted in the introductory that the cutting of individual frame parts 53 to 58, depending on their outer shape, starting from the planar sheet metal and can be done by cutting and / or ablation. The cutting is the partial or complete disassembly of the sheet by cutting operations, for example with a shearing machine or a shearing machine. The removal can be carried out with a thermal separation process, such as a flame cut, laser cut, plasma cut or a water jet cut.

But it is also possible for larger series, that the cutting is done by a punching process. Depending on the selected sheet thickness, the use of laser cutting equipment has proven itself, since not only a quick, re-hollow precise cutting process is possible, but also in a change in shape of the blank part can be quickly adapted to it. Preferably, a non-cutting separation process takes place.

If only a planar construction part is formed from the sheet metal, it is referred to below as a component, irrespective of which separation method this has been used to form from the sheet metal. If, after the cutting process, also a deformation of the component, this is referred to as a forming part.

Furthermore, it is possible for a plurality of frame parts 53 to 58 to be joined together by means of a material-locking connection to form a frame subassembly 59. This frame subassembly 59 can then be combined with other frame parts 53 to 58 to form its own preassembled module 61 together. However, it would also be possible to join several frame subassemblies 59 from different frame parts 53 to 58 in a material-locking manner, and these frame subassemblies 59 can then be connected to the base frame. These connections are preferably made by means of non-positive and / or positive connection means. The connecting means may be formed for example by screws, rivets or else as an enforcing connection (clinching).

The production of the individual frame parts 53 to 58 takes place predominantly from a flat sheet material in a cutting operation. Depending on the required component can be found with one of the previously described cutting operations Auslangen. If, on the other hand, more complicated spatial forms are to be produced, the required outer shape of the frame part 53 to 58 can be cut out of the metal sheet and subsequently shaped to the desired spatial shape with one or more forming processes. In order to save processing costs, individual frame parts 53 to 58 can be produced without cutting and subsequently shaped. It is also possible to cut out individual of the frame parts 53 to 58 in the planar basic form of the sheet metal or else punch out and then transform with one or more forming operations to the required frame part 53 to 58.

In order to achieve a high weight reduction with nevertheless high inherent rigidity of the base frame 51, sheets starting from a sheet thickness of 1.5 mm up to 5 mm are used to form the individual frame parts 53 to 58. By appropriately designed and trained frame parts 53 to 58, a modular system can be created, with which the base frame 51 is created as a structural unit for forming the conveyor vehicle 4.

As can be seen from FIGS. 4 and 5, in this exemplary embodiment, some of the frame parts 53, with the respective frame parts 58 attached thereto, each form its own frame subassembly 59, which is designed such that it is for storage and / or mounting the wheels 20 serve. In this case, the blank of the frame part 53 is formed so that a bracket-shaped configuration is achieved by bending over of sections 70, 71 of the blank. The folded-over sections 70, 71 may additionally be connected to one another in a cohesive manner at the mutually facing end edges. The rib-shaped or web-like frame part 58 can here be materially connected to a planar base part 72 of the frame part 53 and / or to at least one of its folded over sections 70, 71. For a prefabricated structural support part is created, which can be formed without high delay. The connection with other frame parts 54 to 57 and / or frame subassemblies 59 can then take place in a positive and / or positive manner.

In most cases, the conveyor vehicle 4 comprises four pieces of such wheels 20, which are spaced apart in pairs and in the direction of travel 60 from each other. This distancing serves to receive and hold the previously described load-receiving device 46 and optionally the telescopic arms 47 for carrying out the inward and outward movement of the load 3 from the conveyor vehicle 4 into or out of a storage rack 7 of the slider 2. Depending on the production process of the individual Frame parts 53 to 58 will be spoken of components and of formed parts, as has been briefly explained in the introduction. As components, those parts are referred to, which are cut out of a metal sheet and can then be used in their spatial form unchanged to form the base frame 51. As forming parts are those frame parts 53 to 58 referred to, which are formed from a sheet and formed with one or more forming operations to the desired spatial shape out. This transformation takes place in a cold forming process such as bending, pressing, embossing or the like. In these formed parts, the shaping takes place predominantly without cutting, starting from the flat sheet metal. In additional and different cutting and / or punching operations, for example, even exemptions and connection or. Receiving openings are formed with a variety of cross-sectional shapes. These cutting or cutting operations are preferably carried out before the forming process.

The individual frame parts 53 to 58 described above can be connected to each other or to each other depending on the relative arrangement of the same to each other via a cohesive joint connection and / or via a non-positive connection. Under non-positive connection screw connections, rivets or the like are understood here. By means of cohesive joining compounds, in particular welding, adhesive or soldered seams, the above-described individual frame parts 53 to 58 can also be connected to one another. It is also possible to combine these connection variants.

Individual of the frame parts 53 to 58 together with a frame subassembly 59 can form its own subassembly 61. In the present exemplary embodiment, the two first frame parts 53 receiving or supporting the running wheels 20 each have a frame subassembly 59 with the web-like frame parts 58 connected thereto, which in turn form the subassembly 61 with the second frame part 54 connecting them transversely to the direction of travel. The two bearing the wheels 20 and stored first frame parts 53 are formed by console-shaped formed parts. The second frame parts 54 connecting the two first frame parts 53 are formed as a shaped part shaped as a longitudinal profile. In the course of the shaping of the formed parts, these can be formed at these connection points corresponding to the mutual connection. In cohesive joining compounds, this can be done for example by a variety of welding processes. Thus, for example, an electrode welding, inert gas welding or else laser welding can be used. If a frictional connection is selected, individual tabs or webs can be provided, which can have receiving openings for receiving the non-positive connection means.

The assembly 61 can still further comprise the preferably hollow profile-shaped third frame part 55, which connects the console-shaped formed as Umformteile first frame parts 53 and the frame subassemblies 59. Thus, a housing-shaped design of the assembly 61 is created, which in itself already has a high inherent rigidity by the corresponding shape of the individual frame parts 53, 58, 54 and optionally 55.

As already described above, the console-shaped first frame parts 53 serve with the frame parts 58 arranged thereon for holding or receiving or supporting the impeller 20. For this purpose, on the formed as a forming part first frame part 53, in particular its base part 72, a Bearing assembly 62 supported. This bearing assembly 62 may include, for example, a separate bearing housing in which the bearing is accommodated and the bearing housing in turn connected to the first frame part 53, in particular screwed. Regardless, it would also be possible to provide in this first frame part 53, a corresponding enforcement with a peripheral wall part, which is made in a chipless forming process. Due to the high manufacturing accuracy but it would also be possible to support the bearing, not shown here by means of a press fit on the wall part formed from the sheet metal. This can be created in a simple manner, a bearing for the wheels or 20.

In the present exemplary embodiment, the base frame 51 comprises at least two assemblies 61 arranged at a distance from one another in the direction of travel 60, which in turn are connected peripherally in the region of the wheels 20 by the fourth frame members 56 extending in the direction of travel 60. These fourth frame parts 56 are preferably formed in the shape of a hollow profile or tubular. This results in a corresponding distancing of the two modules 61 in the direction of travel 60 from each other. Thus, the base frame 51 forms a arranged in its outer edge region support structure of the two assemblies 61 and the two fourth frame members 56.

To achieve a certain torsional stiffness and achieve a higher intrinsic stiffness of the base frame 51, the marginally in the region of the wheels 20 in the direction of travel 60 extending fourth frame members 56 may be connected by further X-shaped fifth frame members 57 with each other. By mutually cross-shaped arrangement of or the fifth frame parts 57 to each other, a high Aussteifwirkung and thus stability of the entire base frame 51 is achieved. The individual ends of the fifth frame part or parts 57 are connected to the marginally arranged fourth frame parts 56. However, the intersecting or X-shaped fifth frame members 57 may also be formed by a single component, in which the fifth frame members 57 are arranged to one another in a plane. In this embodiment, then the fifth frame part 57 may be formed by a simple stamped part.

Regardless, it would also be possible to individually produce the individual arms of the X-shaped fifth frame member 57 and connect in the region of the intersection in the center with a center part and thus form a single component.

Among other things, the previously briefly described drive arrangement 52 is held or arranged on this base frame 51. In order to create a weight-saving solution here with the least cost of materials, each of the running direction 60 in succession and oppositely arranged wheels 20 are each connected to each other via a drive shaft 63. In order to achieve a weight saving here as well, the drive shaft 63 may be tubular. In order to provide a drive connection between the at least two impellers 20 arranged behind one another in the direction of travel 60 on a first side of the base frame 51, these are coupled or connected to one another via a traction mechanism 64 of a traction mechanism drive 65. As a pulling means 64, for example, belts, chains, belts or the like can be applied. Furthermore, it is provided in this embodiment that in the region of the first side of the base frame 51 in the region of the traction drive 65 on each of the drive shafts 63, a drive wheel 66 is rotatably supported. On the side facing away from the base frame 51 side of the drive wheels 66, the respective wheels 20 are then also rotatably supported on the drive shaft 63.

The traction means 64 is further connected to a drive member 67 shown in simplified driving connection, which is formed for example by an electric motor, servomotor or the like. On the presentation of the supply of energy to the drive member 67 is omitted here, so as not to affect the clarity of the presentation. Preferably, the drive member 67 is equipped with a path measuring device or is the drive member 67 with this in operative connection so as to determine the individual travels of the conveyor vehicle 4 in the rack 2 and to determine exactly.

The longitudinal course of the traction means 64 is selected such that this wraps around the two drive wheels 66 on their upper sides. In this case, depending on the arrangement of deflection wheels 68 which are arranged on mutually facing sides of the spaced apart in the direction of travel 60 drive shafts 63, and the arrangement of a standing with the drive member 67 in drive connection driven gear 69 and another guide wheel 70, a wrap angle in the extent between 160 ° and 200 °, in particular achieved by 180 °. The two supported on the drive shafts 63 drive wheels 66 are arranged in a horizontal arrangement of the conveyor vehicle 4 above the guide wheels 68 and the output gear 69 and the further guide wheel 70. Furthermore, the output gear 69 and the further deflection wheel 70 are arranged approximately one above the other. The traction means 64 extends on sides facing away from one another in the direction of travel 60 approximately vertically toward the output gear 69 and the further deflection wheel 70. The traction means 64 is deflected on the output gear 69 as well as on the further deflection wheel 70 in an approximately horizontal direction and subsequently extends continuously between these two.

At the mutually facing sides, the traction means 64 extends in each case starting from the two drive wheels 66 also approximately vertically toward the guide wheels 68. At the two guide wheels 68, the traction means 64 is deflected in an approximately horizontal direction and then extends continuously between these two deflection wheels 68. Thus, a continuous connection and a transmission of the drive movement, starting from the drive member 67 to the output gear 69 and subsequently achieved by the rotating traction means 64 on the two drive wheels 66.

By this above-described formation of the drive connection between the individual wheels 20, each of the individual wheels 20 form a drive wheel, whereby an all-wheel drive is created, in which with a single drive member 67 Auslangen can be found. Thus, arranged in the region of the first side of the base frame 51 wheels 20 are connected via the traction means 64 in drive connection. The other wheels 20 on the other side of the base frame 51 are respectively coupled via the drive shaft 63 with the wheels 20 in the region of the first side of the base frame 51. Thus, an exact concurrent longitudinal movement of the entire conveyor vehicle 4 in the direction of travel 60 done, whereby even more accurate travel paths can be achieved. Thus, in conjunction with the lightweight construction of the base frame 51 even faster acceleration or deceleration processes can be performed, since a smaller net mass must be moved, accelerated or decelerated during the driving movement. Furthermore, a weight reduction is also achieved by the specially designed all-wheel drive with a small number of drive means, which also has a favorable effect on the entire adjustment operations or travel paths and the time required for this purpose. This makes it possible to approach individual positions in even shorter times, making the entire system even more efficient. Thus, bearing movements of the individual goods 3 can be carried out even faster.

By the breakdown of the base frame 51 in the individual frame parts 53 to 58, they can each separately, for example by cutting and / or punching and optionally forming, produced and then joined together in an automated joining system. Although more complex clamping devices are required by the higher number of separate frame parts, but the cutting or punching operations and forming processes for the frame parts can be made simpler and the frame parts are made as such with a high dimensional and dimensional accuracy.

A particularly economical production of the individual frame parts 53 to 58 can be realized if, for each frame part 53 to 58, a flat sheet metal strip, preferably endlessly from a coil, a punching and / or forming device, in particular a follow-on composite tool, and is passed through them and passes through gradual stamping and forming stations. In this case, a plurality of blanks or blanks is punched out of the sheet metal strip in a stamping process and this formed in a forming process (bending, pressing, rolling, embossing, calibrating) in one or more successive forming step (s) and the described frame part 53 to 58 shaped. The design of the frame parts 53 to 58 provides that this requires almost no mechanical rework after carrying out all forming operations. This automated production with its own punching tools or directly downstream forming stations is only economically feasible for a very large number of items, since here also the tooling costs must be taken into account.

In the transport vehicles used in today's conveyor 4, namely in so-called self-propelled shuttles, in conjunction with shelf storage 2, depending on the transported or to be transported and outsourced transport or load 3, the conveyor vehicle 4 with mutually different manipulation units 73 or units provided. In order to have a high degree of prefabrication or a high number of identical parts for the base frame 51 described above, a separate base or support unit should also be created here in the manner of a modular system, which then, as required, with the manipulation units 73 provided therefor can be equipped. These self-propelled conveyor vehicles 4 can also be referred to as single-level stacker cranes, for which purpose the already used term shuttle or transport shuttle can be used.

The self-propelled conveyor vehicles 4 between the storage warehouses 2 each have the load-receiving device 46, which may be formed differently depending on the load to be transported 3. A first possibility of forming the load-receiving direction 46 has already been shown in greatly simplified schematic form in FIG. 3. Thus, the load-receiving device or the load-receiving devices 46 serves to store the conveyed material or cargo 3 in a rack of a racking 2 and outsource as required from the rack storage 2 again and, for example, a picking, a shipping point or the like.

The conveying vehicle 4, which has been shown in a simplified manner previously in FIG. 3, has the load receiving device 46, which in turn comprises the manipulation units 73 which are distanced from one another in the direction of travel 60 and an actuating or transport surface for the load 3. In this case, the manipulation units 73 are formed by the telescopic arms 47, on which preferably a plurality of drivers 48 are arranged. These can, if necessary, be brought into engagement with the transported material to be transported for the insertion and / or removal movement. This is usually done via a pivoting movement of a located within the telescopic arm 47 in a telescopic arm out on the load 3 superior position. This is well known and will therefore not be discussed further.

FIG. 6 shows a further possible embodiment of the conveyor vehicle 4, again using identical components or reference numerals for the same parts as in the preceding FIGS. 1 to 5. To avoid unnecessary repetition, reference is made to the detailed description in the preceding in Figs. 1 to 5 or reference.

The transport vehicle 4 shown here differs from the transport vehicle 4 described and shown previously in FIG. 3 by the arrangement and design of the manipulation units 73. The transport vehicle 4 also has in turn the base frame 51 described above, which in its basic basic construction is formed identically, as has been previously described in detail in FIGS. 1 to 5.

The load-receiving device 46 in turn comprises the two manipulation units 73 as well as an actuating plane 74, which in the present exemplary embodiment is designed as a support platform 75. Each of the manipulation units 73 comprises a support arm 76 coupled to or attached to the base frame 51, on each of which a longitudinal guide 77 for an actuating arm 78 is arranged. On the actuating arm 78 turn, in particular in its end regions, the previously described driver 48 is provided, which may also be referred to as entrainment organs. The actuator arm 78 is adjusted via a traction drive 79 shown in its longitudinal direction and thus in the conveying direction for storage and retrieval of the transported material.

The drivers 48 are preferably arranged stationarily on the actuating arm 78 and are as required with the transported or conveyed conveyed by an adjustment of the support arm 76 in the transverse direction with respect to the conveying direction of the load 3 during loading and unloading with this in engagement or Disengaged, as is well known.

The setting plane 74 for bearing the load 3 on the conveyor vehicle 4 may be designed to be different from each other in the two previously described conveyor vehicles 4. Thus, it is possible to choose either the fixed support platform 75, or else to form the placement plane 74, for example in the form of a conveyor belt, a roller drive or the like.

FIG. 7 shows in simplified form the uniform base frame 51 for forming the previously described conveyor vehicles 4 with their different load receiving devices 46. In this case, the same reference numerals or component designations as in the preceding FIGS. 1 to 6 are again used for the same parts. To avoid unnecessary repetition, reference is made to the detailed description in the preceding in Figs. 1 to 6 or reference.

The base frame 51 serves as a central supporting or receiving unit for the formation of the conveyor vehicles 4 similar components. This may be, for example, the or the drive members 67 for the wheels 20, the drive for the manipulation units 73 and other components components. The base frame 51 in turn may in turn comprise the frame subassemblies 59 and the assemblies 61 with their frame parts 53 to 58. For better clarity, reference is made here to the clearer representation in FIGS. 4 and 5 or reference is made.

The drive for the conveyor vehicle 4 with its base frame 51 may include the unitary drive member 67 which drives the wheels 20 via the traction means 67 and the traction mechanism drive 65 formed therefrom. Thus, the wheels 20 are also driving wheels for the conveyor vehicle 4 simultaneously.

Furthermore, a further drive unit 80 is also provided on the base frame 51, which is in drive connection for the insertion and removal movement with the or the manipulation units 73. For example, the drive unit 80 may comprise its own drive member 81, for example in the form of a drive motor, which may be in drive connection with a splined shaft 82 with the interposition of a gear arrangement. The spline shaft 82 is connected via drive means (not shown or designated) to the respective manipulation units 73 in drive connection. This makes it possible to be able to transmit the drive movement via the drive unit 80 to the manipulation unit 73 or manipulation units 73. Thus, this entire drive unit 80 is part of a common base frame 83rd

Furthermore, an electrical control device 84 is indicated in the center of the base frame 51 in a simplified manner. This electrical control device 84 may in turn be formed of several control and / or regulating modules, which for the ferry operation of the conveyor vehicle 4 and the further associated Verstellvorgänge for the storage and retrieval movements of the previously described manipulation units 73, optionally with their drivers 48, control or, if necessary, carry out further control or measuring operations.

The base frame 83 with the previously described base frame 51, with the drive unit 80, with the drive member 67, with the traction mechanism 65 and with the electrical control device 87 thus represents a uniform for all vehicles 4 similar design unit. It can only differences in the training or assembly of the control device 84 in dependence on the manipulation units 73 to be driven therewith. Thus, a base frame 83 has been created, on which the previously described, different manipulation units 73, namely in the form of the telescopic arms 47 or even the support arm according to FIG. 6 can be arranged, held and operated.

For this purpose, between the base frame 83, in particular the base frame 51, and the load receiving devices 46, in particular their manipulation units 73 subsequently described in more detail interfaces 85, 86 are provided. For example, the first interface 85 may be formed by a mechanical interface and the further interface 86 by an electrical interface.

In Fig. 8 shows a possibility of arrangement and design of the interfaces 85, 86 on the conveyor vehicle 4 shown on a larger scale, via the interfaces 85, 86, the telescopic arms 47 comprehensive load-receiving device 46 are coupled to the base frame 83. In this case, each of the manipulation units 73 of the load receiving device 46 is preferably coupled to the base frame 83 via at least one mechanical interface 85 and / or an electrical interface 86.

Here, the manipulation device 73 via two in the transport direction of the load 3 spaced from each other, arranged mechanical interfaces 85 with the base frame 83, in particular the base frame 51 - coupled in the present embodiment with the frame subassembly 59 and connected.

Thus, in this embodiment, the mechanical interface 85 on the base frame 83 comprises at least a first mechanical interface part 87 and on the load receiving device 46, in particular on the manipulation unit 73 with the telescopic arms 47, at least a second mechanical interface part 88. So forms the first , mechanical interface part 87 a in the case of operation vertically aligned contact surface of the portion 70 of the frame subassembly 59 from. In this angularly bent component, for example, openings or bores may be provided, via which the manipulation unit 73 can be fastened or coupled with the interposition of fastening means not designated in any more detail.

Furthermore, the electrical interface 86 is shown schematically simplified, in which a first, electrical interface part 89 on the base frame 83 and further to the load receiving device 46, optionally with the interposition of a line connection, a second, electrical interface part 90 is provided or arranged. For example, the first electrical interface part 89 may be arranged on the base frame 51, in particular on the frame part 54 of the assembly 61. This first, electrical interface part 89 may be in contact via a line connection, not shown, with the control device. The second interface part 90 which can be coupled thereto can be in line connection with the manipulation unit 73 via a schematically indicated line connection, such as, for example, a cable or the like. This training is shown in simplified form in the upper part of Fig. 8.

However, it would also be possible for the second electrical interface part 90 to be arranged directly on the load receiving device 46, in particular of the manipulation unit 73, and for the first electrical interface part 89 to be in line connection with the control device 84 with the interposition of a mostly flexible line connection. In order for a line connection can be prepared by the fact that the two electrical interface parts 89, 90 coupled to form the electrical interface 86 with each other. This can be achieved for example by a plug connection or the like.

This possibility just described is shown schematically simplified in the lower part of FIG.

In order to precede different distances between the oppositely arranged manipulation units 73, a spacing element 91 can still be arranged between the first mechanical interface part 87 and the second mechanical interface part 88 of the mechanical interface 85 as a distance bridging. Regardless of this, it would also be possible to provide a telescopic cylinder or other adjusting and bearing elements in order to be able to perform a variable width adjustment between the oppositely arranged manipulation units 73.

The two first and second electrical interface parts 89, 90 may in turn be formed, for example, by a plug 92.

In a horizontal orientation or position of the base frame 83, a vertical insertion of the entire manipulation units 73 take place and then in the region of the mechanical interface 85 a holding connection, for example via connecting means, such as screws or the like. If this coupling takes place via the mechanical interface 85, the electrical connection or coupling of the manipulation unit can take place via the electrical interface 86. The design of the electrical interface 86 is dependent on the drive elements to be controlled or moved on the manipulation unit 73. The corresponding electrical switching components are already provided on the pre-installed control device 84 of the base frame 83.

FIG. 9 shows a detail of the conveying vehicle 4 shown in simplified form in FIG. 6 on a larger scale, wherein in particular the representation of trim parts or the like has been dispensed with for the sake of better clarity.

In this support arrangement shown here, the connection for carrying out the adjustment movement of the manipulation unit 73 takes place in the transverse direction to the conveying direction of the load 3 via a pivot lever assembly 93. A further guidance and support of the manipulation unit 73 can be attached to the in FIGS. 4, 5 and 6 shown, in particular tubular-shaped frame parts 56 take place. In Fig. 6, this Abstützmöglichkeit by a attached to the manipulation unit 73, but unspecified roller bearings can be seen. This support can take place on both frame parts 56 and can form one of the mechanical interfaces 85, as shown in FIG. 6 in the left front area.

A possible further mechanical interface 85 is also provided between the manipulation unit 73 with the interposition of the pivot lever assembly 93 also in the region of the frame subassembly 59. In the present exemplary embodiment, the first, mechanical interface part 87 is provided on the base part 72 of the frame subassembly 59, which likewise forms or represents a vertically aligned contact surface when the transport vehicle 4 is in the operating position. The second, mechanical interface part 88 is formed on the swiveling lever arrangement 93 connected to the manipulation unit 73, via which the holder or fastening of the manipulation unit 73 on the base frame 83 now takes place.

The electrical coupling or connection of the manipulation unit 73 also takes place here again via the electrical interface 86 with its first and second, electrical interface part 89 and 90. These may also be in the form of a plug 92. Here again, it is possible to arrange the first, electrical interface part 89 fixedly on the frame part 54 of the frame subassembly 59 of the base frame 51. The second, electrical interface part 90 can in turn, for example, with the interposition of a line connection with the manipulation unit 73 and arranged there, unspecified, drive and / or measuring organs or sensors are in line connection.

But it would also be possible in turn that the second electrical interface part 90 directly to the load receiving device 46, in particular the manipulation unit 73, is arranged and the first electrical interface part 89 with the interposition of a mostly flexible line connection with the control device 84 in line connection, such as this has previously been described in FIG. 8.

In the case of all the above-described different embodiments of the conveyor vehicle 4 in the region of its manipulation units 73, either only the mechanical interfaces 85 or only the electrical interfaces 86 can be provided. Preferably, however, both the mechanical interfaces 85 and the electrical interfaces 86 are formed so as to provide a modular system in which, depending on the need for uniform base frames 83 with the standard components arranged thereon and the first interface part 87 and / or 89 a need-based arranging Manipulation units 73 can take place.

For the sake of order, it should finally be pointed out that for a better understanding of the construction of the conveyor vehicle 4, in particular its base frame 51, this or its components have been shown partly unevenly and / or enlarged and / or reduced.
