    The invention relates to a stacker crane with a movable along a lower rail and an upper guide rail mast, with a movable along the mast on a lifting pallet truck, arranged with a mast side opposite to the truck side mast support and with a drive for support on the Running rail carrying chassis.
    In a known storage and retrieval unit of this kind (EP 2 502 873 A1), a chassis supported on a running rail via a drive is provided, on which the mast is arranged in a middle section. On the mast side facing away from the chassis end with a travel drive, a mast support is articulated between the mast and the end of the chassis opposite the travel drive.
    The lifting carriage, which can be moved along the mast on a lifting guide, is located on the side of the chassis facing the driving drive, so that it can only be lowered to the chassis and not into the area of the running rail. Since the mast is pivotally mounted on the chassis and the mast support can be adjusted in length, the mast can be adjusted in its inclination position. Although the articulated mounting of the mast and the mast support prevents torque transmission from the mast to the chassis, but the chassis is subjected to the load due to the mast and its load on bending, which requires a relatively heavy chassis construction.
    In order not to have to accept the Hub Restraint of the lift truck through the chassis, it is also known (EP 2 589 550 A1) to arrange the mast at one end of the chassis and by one at the other
    Support the chassis end hinged mast support, so that above the chassis projecting, down-stepped load-carrying means of the van can be lowered below the level of the floor of the chassis. A prerequisite, however, is a storage and retrieval unit, which is mounted on two rails, between which the load can be lowered accordingly. With the arrangement of the mast in the area of a chassis end while bending moments of the chassis due to the weight load through the mast can be largely avoided, but the bending moments must be absorbed, which are transmitted by a torque load of the mast on the chassis.
    The invention is therefore based on the object, a movable along a running rail storage and retrieval system so that despite a comparatively lightweight construction, the loads occurring can be advantageously removed to the rail and the otherwise occurring by a chassis restrictions in terms of Hubwagenbewegung not be accepted ,
    Starting from a storage and retrieval unit of the type described above, the invention solves the problem by the fact that the mast and the mast support form the chassis and that the drive each has a arranged on the mast and the mast support drive group, the two drive groups in one at the foot of the Masts and the mast support provided storage rack are stored.
    Since no separate chassis is provided, which absorbs in particular the loads through the mast and its loads and over the drive on the rail, but the mast and the mast support itself form the chassis, resulting in respect to the prior art significantly lighter and stiffer Construction. Due to the omission of a separate chassis, the wheels of the two drive groups, which usually take over the side guide, provide in storage racks at the foot of the mast and the mast support. These storage racks can with smaller masts by the mast or the
    Mast support itself be formed. For higher demands on the load capacity separate storage racks can be used, the z. B. in the foot of the mast or the mast support. Thus, since the mast and the mast support are supported load-bearingly for each other on wheels of separate drive groups on the running rail, the bending moments otherwise occurring in the region of the chassis according to the mast reception and support are avoided. In addition, the rigidity of the construction is significantly increased.
    The waiver of a separate chassis brings not only advantages in terms of design simplification and weight savings with it, but also eliminates the given by a separate chassis limitation of the travel of the lift truck in its lowering to the lowest position because of the truck along the mast to can be lowered to the rail. This is especially true when the lift guide for the lift truck extends below the top of the drive rail for the drive. For a given guide length for the pallet truck in the region of the rail down extended lifting guide means a shorter guide length for the truck above the guide rail, which brings an increase in the travel of the lift truck in the upper guide rail for the mast with it.
    If the mast and the mast support are connected to form a triangle, the mast and mast support form a construction of sufficient strength, in particular if this triangle is stiffened like a truss or is formed by a connecting plate between the mast and the mast support. However, a rigid connection between the mast and mast support is by no means mandatory. So mast and mast support can also be hinged together, the distance between the drive groups of the mast and the mast support z. B. can be adjusted by an actuator so that the distance between the drive groups of the mast and the mast support, inter alia, influence on the rigidity of the construction can be taken. to
    Acceleration of the storage and retrieval unit can thus be chosen a greater distance between the drive groups, which can be kept small in the end of the rack aisles.
    If a belt drive is provided for the lift truck, then its endlessly guided belt can be guided over a drive arranged on the bearing frame of the mast support to a bearing arranged on the bearing frame of the mast support drive to secure by the displacement of the belt drive on the side of the mast support an advantageous weight distribution. Due to the lack of a separate chassis, there is sufficient space between the mast and the mast support for this purpose.
    For tensioning the endlessly guided belt of the belt drive usually a clamping device is provided. So that this clamping device does not limit the travel of the lift truck in the lower or in the upper end position, one end of the belt can be fastened to a clamping plate connected to the pallet truck and the other end of the belt drive to a clamping plate which can be adjusted by means of a tension drive in the belt longitudinal direction the two juxtaposed clamping plates overlap each other in the belt longitudinal direction, so that the space requirement of the tensioning device in the belt longitudinal direction substantially corresponds to the length of the clamping plates increased by the tensioning travel.
    To drive the storage and retrieval device along the rail can be provided in a conventional manner a wheel drive, in particular a co-operating with the running rail friction drive or one with one of the rail associated rack gear. In this case, it is advisable to arrange the wheel drive on the support frame of the mast support in order to achieve a favorable weight distribution between the wheels of the mast and the mast support. Instead of a cooperating with the running rail or a rack wheel drive but also the one hand, the mast and on the other hand, the mast support associated with groups on a along the
    Running rail extending revolving drive can be connected with the help of the storage and retrieval unit along the rail can be moved. The two drive groups interconnecting Trum of the circulation drive can take over the connection between the mast base and foot of the mast support, because this strand of the circulating drive is claimed according to the forces between mast and mast support only to train.
    To expand the capabilities of a storage and retrieval device according to the invention, the mast support may have a lifting guide for a truck, especially if the mast support acts in the region of the upper end of the mast, so that the pallet truck of the mast support can serve the shelf in full, but not mandatory is.
    Finally, with high demands on the load capacity on the mast support side facing away from the mast connected to the mast by tension or compression struts mastparalleler guide mast is provided, which is supported on a drive group on the running rail and a Hubtrieb for between the mast and the guide mast guided lift truck has. Since the guide mast essentially only has to accommodate the executives for the lift truck, a connection with the mast is sufficient over pressure or tension struts, especially since the proportionate weight of the loaded lift truck is removed via the guide mast assigned to the drive group on the running rail.

    The storage and retrieval unit according to FIGS. 1 to 5 has a mast 1 and a mast support 2, which forms a truss-like stiffened framework with the mast 1. The mast 1 with the mast support 2 is movable along a running rail 3 and is held in the upper end of a guide rail 4, using side guide rollers 5. The mast 1 and the mast support 2 form a self-supporting chassis, via a drive on the rail 3 is supported load-bearing. This drive forms two on the one hand the mast 1 and on the other hand the mast support 2 associated drive groups 6, 7, which comprise a weight-removing impeller 8 and the web of the running rail 3 laterally employed guide rollers 9, 10. In addition, securing rollers 11 are provided which engage under the track of the running rail 3 and prevent lifting of the drive groups 6, 7 from the running rail 3. The drive groups 6, 7 have in the illustrated embodiment of the mast 1 and the mast support 2 separate storage racks 12, in which the impeller 8, the lateral guide rollers 9, 10 and the backup rollers 11 are mounted. The storage racks 12 are shown in FIGS. 4 and 5 essentially formed by two interconnected side walls 13, between which the rollers 8 and the backup rollers 11 are mounted. According to FIG. 4, the storage rack 12 is inserted into the base of the mast 1 forming a box profile via spacers 14. The storage rack 12 of the mast support 2 is attached to this mast support 2, for example by welding.
    The lift truck 15 is movable on a lifting guide 16 along the mast 1 and can be moved by means of an endless belt drive 17. The arrangement is made such that the belt 18 of the belt drive 17 is guided over the bearing frame 12 of the mast 1 deflection rollers 19 to a arranged in the bearing frame 12 of the mast support 2 drive 20, via which a guide roller 21 for the toothed belt 18 is driven , Depending on the direction of rotation of the drive 20, the lifting carriage 15 can thus be moved along the lifting guide 16 on the mast 1.
    4, the lifting guide 16 for the lifting carriage 15 extends below the upper edge of the track of the running rail 3 downwards, wherein the profile of the mast 1 in the region of the guide rail 3 has a recess 22. Because of this on the rail 3 downwardly above the lifting guide 16 for the truck 15, the truck 15 can be lowered according to FIG. 1 to the running rail 3. In order to accommodate the load of the lift truck 15, a certain by the distance between the guide rollers 23 of the lifting in the direction of the lifting guide 16 guide length is observed. Since the lower guide rollers 23 come to lie below the load bearing 24 due to the described design specifications at a distance, above the load receiver is only a portion of the guide length, so that the truck 15 can take a better end position in the upper guide rail 4.
    For tensioning the belt 18 of the belt drive 17, a tensioning device 25 is provided which, according to FIGS. 6 and 7, has clamping plates 26 and 27 for the two ends 28 and 29 of the belt 18 to be joined together. While the clamping plate 26 is connected to the end 28 of the belt 18 against displacement with the lift truck 15, the clamping plate 27 is slidably guided for the other end 28 of the belt 18 in the lift truck 15 in the longitudinal direction of the belt 18 and is supported by a tensioning drive 30, the is preferably designed as a spindle drive and serves to adjust the belt tension. Since the two clamping plates 26, 27 are arranged next to each other and overlap each other in the longitudinal direction of the belt 18, a length of the clamping plates 26, 27 limited to the clamping path results in a limited length for the tensioning device 15 in the direction of the belt longitudinal axis, so that the pallet truck 15 despite the deflection of the belt 18 to the pulleys 19 can be lowered to the running rail 3 or raised in the region of the upper guide rail 4.
    To drive the suspension formed from the mast 1 and the mast support 2, a wheel gear is provided which is formed according to the embodiment as a cooperating with the running rail 3 friction gear. The lateral guide rollers 10 of the drive group 7 are pressed laterally as friction rollers on the vertical web of the running rail 3 and driven by a motor 31.
    The embodiment of FIGS. 1 to 7 illustrates an embodiment of a storage and retrieval device according to the invention, which due to the fact that is dispensed with a separate chassis and the mast 1 and the mast support 2 form a self-supporting chassis, the two drive groups 6 and 7 on the rail 3 is supported, for example, can be dispensed with a rigid triangular union between the mast 1 and mast support 2. Fig. 8 shows such an embodiment in which the mast support 2 is articulated via an upper hinge 32 on the mast 1. Mast 1 and mast support 2 are each supported by the drive groups 6, 7 on the running rail 3, wherein each drive group 6, 7 is assigned its own drive 33. These traction drives 33 are shown as friction wheel drives with lateral guide rollers 10 and are each controlled so that the distance of the drive groups 6 and 7 from each other can be adjusted and regulated according to the respective operating conditions. This makes it possible to change the base of the storage and retrieval unit according to the respective requirements.
    In Fig. 8 is also indicated that not only the mast 1, but also the mast support 2 lifting guides 16 can carry for a truck 15. In this case, it is advisable to control the two trucks 15 each separately via separate drives 34, which are preferably connected to belt drives 35 for the adjusting movement of the lift truck 15.
    The particular determined by the distance of the two drive groups 6 and 7 base of a storage and retrieval device according to the invention can be determined by a running along the running rail 3 circulating drive 36, as shown in FIG. 9, when the two drive groups 6 and 7 are respectively set on Antriebstrum 27 of the circulation drive 36. Due to the fact that the Antriebstrum 37 between the two drive groups 6 and 7 can be claimed only on train due to the occurring loads on the stacker crane, the definition of the base of the stacker crane by the indicated in Fig. 9 connection to the Antriebstrum 37 by tensile connections is sufficient 38. For the sake of clarity, the drive groups 6 and 7 are indicated only by the wheels 8 in FIG. 9.
    Thus, the truck 15 also heavy loads can be recorded, can be provided according to FIG. 10 on the mast support 2 side facing away from the mast 1 connected to the mast 1 by tension and compression struts 39 mastparalleler guide mast 40, via a drive group 41 is supported on the running rail 3 and has a lifting drive 42 for the guided between the mast 1 and the guide mast 40 lift truck 15. In this case, a synchronization of the Hubtriebs 42 and the drive 20 for the belt drive 17 on the side of the mast 1 to provide. But it can also be a common drive for the lifting movement of the lift truck 15 on the side of the mast 1 and on the side of the guide mast 40 are provided.
