The invention relates to a conveyor vehicle, in particular a self-propelled shuttle, for loading and unloading of cargo into or out of a storage rack of a warehouse, comprising a base frame of a plurality of frame parts, several Laufröder and a load handling device.

A transfer shuttle for loading and unloading cargo into and out of a storage rack of a rack warehouse from US 2011/0008138 A1 has already 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.

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 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 RahmenteiJe are materially joined to at least one frame subassembly and these at least one frame subassembly force and / or positive fit is connected to at least one further frame part and / or to at least one further frame part of another frame subassembly N2011 / 17400 M r 'η nf η ~ ΐ i ΟΛ 1 Λ C λ c D / HC d ηης ιη'λ7 25 15:43 57 22-07-2011 6/37 • * -2-

The advantage here is that the majority of the frame parts are formed from thin sheet metal without cutting in the form of simple, mostly planar components and / or formed from sheet metal forming parts. 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 Versteflbewegungen the entire conveyor vehicle can be achieved, whereby the storage and retrieval operations can be performed in less time. This further increases the productivity of the entire storage system.

A further embodiment according to claim 2 is also advantageous. As a result of the formation of individual subassemblies for forming the base frame, a certain degree of prefabrication of individual components can already take place, as a result of which a rapid completion of the entire transport vehicle is subsequently made possible. In addition, high strength or inherent stiffness of the base frame can be achieved despite the used, ing own mass of the individual frame parts. By using individual frame parts In a different shape, a modular system can be formed.

A further advantage is an embodiment according to claim 3, as an additional stiffening of the assembly can be achieved, creating a housing-shaped design of the assembly is created.

Due to the construction according to claim 4, it is possible to easily form a proper bearing for the or the wheels on the console-shaped first frame part of the frame subassembly.

According to another embodiment variant according to claim 5 seen in the direction of travel, an exact relative arrangement of the modules is created to each other, in which with minimal component wall Auslangen is found.

Also advantageous is a development according to claim 6, since 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. N2011 / 17400

In the embodiment according to claim 7, it is advantageous that a sufficient stiffening of the outer frame parts of the base frame can be achieved with the smallest space requirement.

Finally, however, is an embodiment as described in claim 8 possible, since so the overall dynamics of the movements, in particular the acceleration and the deceleration, can be significantly improved in both drive directions. Thus, starting from all driven Laufrä-the, regardless of the direction of movement, regardless of the load and the weight distribution, always achieved 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. For a positionally accurate Ansteuem or approaching the individual acquisition or dispensing positions is achieved, whereby an even higher density in the Regaflager can be achieved. Furthermore, an additional reduction of the dead weight or the net mass of Förderfahizeuges can be achieved in conjunction with the simply built base frame. Thus, the small number of components also simplifies the entire design.

By choosing the cohesive joint connection is achieved so that can be dispensed with additional Verbindungsmittei and thus the weight or 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 eggs. This is particularly advantageous for damage and maintenance.

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

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

The transport devices 24a, 24b are thus independently (decoupled) adjustable from one another between the shelf levels 11 and to the height level of each rack level 11, so that loads 3, such as containers, cartoons, trays or the like, between the transport devices 24a, 24b and buffer locations 13a, 13b can be promoted. Preferably, the transport devices 24a, 24b are each formed by a drivable conveyor track, such as a accumulation roller conveyor, accumulation belt conveyor and the like. It also proves to be advantageous if the transport devices 24a, 24b can consecutively receive a plurality of loads 3, preferably up to four loads 3 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 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 shelf levels 11 to the height level of each shelf 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, can also be promoted between the transport devices 24a, 24b and a first pre-zone conveyor.

The first pre-zone conveyor follows the load-lifting device 5 and includes a first conveyor 31a and a second conveyor 31b which are mutually parallel with each other. 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 conveying 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 at a distance from each other, so that the transport devices 24a, 24b in each case in their lowered on the conveyor plane 30 transfer or transfer position between N2011 / 17400 99 // 17/9/111 1 rn 1 Nr 841 R p ms / rm 25 25 14/37 15:49:30 22-07-2011 • ft ft * ft * ·· «1 · · * • ft ft ·« «ft * • ft · ft · ft # ft · ft • The trailing edges of the conveying devices facing one another are movable.

In this case, goods 3 are conveyed by the first conveying device 31 to the load-lifting device 5 via the first conveying device 31a and goods 3 are conveyed away from the load-lifting device 5 to the first conveying zone 5 through the second conveying device 31b.

On the second Regatlagerseite 10 front side of the rack storage 2, the conveyor vehicle 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 which is vertically adjustable via a lifting drive 36. 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 receiving device 35 or guideway can be adjusted between the shelf levels 11 to the height level of each shelf level 11 and the height level of a conveyor level technology 43 so that load 3 can be promoted between the receiving device 35 and a second Vorzonen conveyor.

The second pre-zone conveyor system adjoins the conveyor vehicle lifting device 6 and comprises a first conveyor device 44a and a second conveyor device 44b, which run parallel to each other at a mutual distance. The stationary conveying devices 44a, 44b are each formed by a lockable 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 one another 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 conveying technology 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 conveying device 44a goods 3 are conveyed by the second pre-zone conveyor to the conveying vehicle lifting device 6 and conveyed via the second conveyor 44b cargo 3 from the conveying vehicle lifting device 6 to the second Vorzonen conveyor.

By means of the conveying vehicle lifting device 6, at least one foreder vehicle 4 can now be converted between the control plane 11.

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 be 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 formed in a lightweight construction or a lightweight construction by frame members 53 to 58 formed from sheet metal or comprises the base frame 51 this. In the present embodiment, these frame parts 53 to 58 form 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 will be noted at the outset that the cutting of individual frame parts 35 to 58, depending on their outer shape, starting from the planar sheet metal and can be done by cutting and / or removal. 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. It is N2011 / 17400 00/07/0/111 1 CG / 1 M r D / 11G p ni7 / no7 25 15:52:20 22-07-2011 18/37 · · · «· * ···« « · *** ι -14-but also possible for larger series, that the cutting is done by a punching process. Depending on the selected sheet metal thickness, the use of laser cutting systems has proven itself, since not only a quick, reverberant 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 structural part is formed from the sheet metal, the following is spoken of a component, regardless of which separation method it has been formed from the sheet. If, after the cutting process, a deformation of the component is also carried out, this is referred to as a formed part

Furthermore, it is possible that a plurality of frame elements 53 to 58 are joined together by means of a material-coherent 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 form-locking 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 metal material in a cutting process. 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 on processing costs, individual frame parts 53 to 58 can be produced without cutting and subsequently reshaped.

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 a separate frame subassembly 59, which is designed such that it supports and / or holds the running wheels 20 serve. In this case, the blank of the frame part 53 is formed so that a console-shaped configuration is achieved by edge edges of sections 70,71 of the blank. The folded-over sections 70, 71 may additionally be connected to one another in a material-locking 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 is used to hold and hold the load bearing device 48 described above and optionally the telescopic arms 47 for carrying out the input and Auslagerfoewegung the load 3 from the conveyor vehicle 4 in or out of a storage rack 7 of the rack 2.

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 space shape out. This transformation takes place in a cold enveloping process such as bending, pressing, embossing or the like. In these Umfonnteilen the shaping takes place starting from the flat sheet predominantly without cutting. In additional and different cutting and / or punching operations, for example, even exemptions as well as connecting or receiving openings can be formed with a wide 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 one another depending on the relative arrangement of the same relative to one another via an integral joining connection and / or via a friction connection. Under non-positive connection screw connections, rivets or the like are understood here. By means of staff-connected joint connections, 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.

Some of the frame parts 53 to 58 can form a separate assembly 61 together with a frame subassembly 59. 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 to them, 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 members 54 connecting the two first frame members 53 are as 22/07/2011 15:56

The assembly 61 can still further comprise the preferably hollow-profiled third frame member 55, which connects the bracket-shaped first frame parts 53 or the frame subassemblies 59 formed as formed parts. This creates a housing-like design of the assembly 61, which already has a high intrinsic rigidity by the corresponding shaping of the individual frame parts 53, 58, 54 and optionally 55.

As already described above, the console-shaped first frame parts 53 with the frame segments 56 arranged thereon serve in each case for holding or receiving or supporting the impeller 20. For this purpose, a bearing arrangement 62 is mounted on the first frame part 53, in particular its base part 72, designed as a formed part This bearing assembly 62 may for example comprise a separate bearing housing in which the bearing is taken up and the bearing housing in turn connected to the first frame part 53, in particular screwed. Regardless, it would also be possible to voizusehen in this first frame part 53 a corresponding enforcement with a circumferential wall part, which is hergesteilt in a chipless forming process.

In the present exemplary embodiment, the base frame 51 comprises at least two subassemblies 61 arranged at a distance from one another in the direction of travel 60, which in turn are peripherally connected in the region of the wheels 20 by the fourth frame parts 56 extending in the direction of travel 60. Preferably, these fourth frame parts 56 are formed hollow profile-shaped 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 rigidity and achieve a higher inherent rigidity 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 to each other by further X-shaped fifth frame members 57. By mutually cross-shaped arrangement of or the fifth frame side 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 manufacture the individual arms of the X-shaped fifth frame part 57 and to connect them in the region of their 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 provide a weight-saving solution with the least expenditure of material, too, the DOs // 17 / ΟΠ1 1 1E-E7 M r are arranged one after the other in the direction of travel 60 and opposite one another

Wheels 20 each connected via a drive shaft 63 with each other. In order to achieve a weight saving here as well, the drive shaft 63 may be tubular. To a drive connection between the at least two in

Direction of travel 60 successively arranged impellers 20 on a first side aes urunaranmens bi shadow, they are coupled via a traction means 64 of a traction mechanism 65 with each other or connected. 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 traction drive 65 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 then the respective wheels 20 are also rotationally fixed held on the drive shaft 63.

The traction means 64 is further in drive connection with a drive member 67, shown in simplified form, 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 chosen such that this wraps around the two drive wheels 66 at their upper sides. In this case, depending on the arrangement of deflection wheels 68, which are arranged on mutually facing sides of the drive direction spaced apart in the direction of travel 60 drives 63, and the arrangement of a standing in driving connection with the drive 67 output drive gear 69 and another guide wheel 70, a wrap-around angle in 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 Umfenkräder 68 and the driven gear 69 and the further guide wheel 70. Furthermore, the output gear 69 and the further guide wheel 70 are approximately one above the other N2011 / 17400 oo / n7 / omi i c; - r; «No. · R41R P.023 / 037 25« * * 15:56:40 22-07-2011 24/37 -20 arranged. 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.

On the sides facing each other, the traction means 64 also extends approximately vertically from the two drive wheels 66 to the deflection wheels 68. The traction means 64 is deflected in an approximately horizontal direction on the two deflection wheels 68 and subsequently extends continuously between them These two Umlenkrädem 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 provided, in which with a single drive member 67 Auslangen can be found. Thus, in the region of the harvested side of the base frame 51 arranged wheels 20 are above the traction means 64 in drive connection. The other wheels 20 on the other side of the Gmndrahmens 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 carried out, since a smaller mass must be accelerated or delayed during the travel 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, Ν2011ΛΙ7400 OO / Π7 / 0Π11 No. · Rd 1 R 024 / (137 25 15:57:25 22-07-2011 25/37 * * • * «» • By means of which the entire system can be made even more efficient, bearing movements of the individual goods 3 can be carried out even more quickly.

As a result of the subdivision of the base frame 51 into the individual frame segments 53 to 58, they can each be produced separately, for example by cutting and / or punching and, if appropriate, reshaping, and then joined together in an automated joining system. Although more complex clamping devices are required due to the higher number of separate frame parts, the cutting or punching processes and forming processes for the frame parts can be made simpler and the frame parts can be produced 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 fed by a coil, a punching and / or forming device, in particular a follow-on composite tool, and passed through this In this process, a large number of blanks or blanks are punched out of the metal strip in a stamping process and formed in a forming process (bending, pressing, rolling, embossing, calibrating) in one or more successive stamping steps and molded to the described frame part 53 to 58. 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 economically replaceable only with a very large number of pieces, since the tool costs must be taken into account here.

For the sake of order, it should finally be pointed out that for a better understanding of the structure 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 in size. 09 / n7 / 9fiil ις · ςα
