    State of the art:
    In a telescope described in US9150355B2 a telescopic drive realized with ropes is proposed. In the drawings, the telescopic part which is located between the stationary and the telescopic telescopic part is shown (center table). He is moved by a wound around a driven drum rope along the guide. Since this drum occupies the space under the linear guides, the pivot point and the drive for the gripper fingers can be arranged only above the linear guide. This, in turn, causes, when moving low goods and piece goods such as e.g. Trays the force not near the pivot point of the gripper finger, but rather attacks the ends of the gripper fingers. This causes a high adverse bending load in the gripper fingers. Since the main body of the central telescope part has no transverse webs, it must be made of a solid material with a relatively high thickness, which in turn adversely affects the space occupied and the storage density to be achieved in the warehouse.
    The documents AT516410B1 and EP2526032B1 describe shuttle vehicles for picking up and dropping off general cargo. In the drawings, the embodiment of the telescopic part which is located between the stationary and the telescopic part which can be extended furthest in the z direction (center table) is represented by an extruded profile. However, such profiles are only economically producible from aluminum. However, since the guide parts can only be made of steel materials due to the required service life, there is an unfavorable combination of materials, which causes problems especially with longer telescopic parts used in frozen storage by arcuately shaped telescopic arms.
    Furthermore, such a construction solves only one application. As soon as a different cross-section of the telescopic arm becomes necessary due to other conditions in the warehouse, new extrusion tools must be purchased, because it is not possible to insert additional stiffeners. Furthermore, a completely new telescopic arm must also be developed, if it is necessary to change the telescopic drive and the toothed rack meshing with the telescopic drive from the bottom to the top or vice versa.
    Task:
    The object is to provide a telescopic arm which has a plurality of extendable tables, wherein the furthest extendable table carries pivotable gripping fingers. In particular, since the width of the telescopic arm determines the distance with which the goods can be stored in the warehouse to each other, a loss of space or space is multiplied by the number of available parking spaces in the camp. It is therefore crucial to produce a telescopic arm as narrow as possible.
    Another task is to avoid a change in shape during temperature changes and thus to ensure reliable storage and retrieval. This is of great importance especially for telescopic arms that reach far into the shelf.
    In this case, the production of the telescopic arm should be possible in spite of many specially adapted to the cases of application cost and without tool change. It is a kit to be provided, from which a variety of configurations can be easily derived. This concerns above all the adaptation of the telescopic arm cross-sections to the occurring load of the various payloads and Teleskoparmlängen. Another requirement of the kit is depending on the situation in the warehouses to arrange the rack and thus engaged telescopic drive either above or below the linear guide.
    Execution:
    The present invention solves the problem set such that the center table is formed from a rack forming sheet metal profile which has a central web receiving the two guide parts and that the center table has at least one transverse web.
    Benefit Description:
    Since the center table is formed from a clamped between the guide members sheet metal profile, which also forms the rack and is stiffened by a crossbar, results over the prior art, a much lighter and narrower construction. For higher requirements, two additionally stiffened between the two guide members stiffening profiles cause the necessary transverse rigidity and torsional rigidity. The fact that the upper longitudinal edge web of the two stiffening profiles is connected through the middle web of the sheet metal profile, a torsion-resistant center table is also in the expression with overhead rack or overhead telescopic drive allows.
    For smaller required Ausfahrwegen the telescopic arm, however, either only a stiffening profile can be provided or waived entirely on a stiffening profile. For particularly short extension paths can also be dispensed with the crossbar of the sheet metal profile.
    It is thus a kit provided with all the characteristics with respect to cross section, extension path and telescopic drive arrangement can be covered.
    Depending on which storage and retrieval device or load-handling device of the telescopic arm is constructed, due to the space available, an overhead or a bottom telescopic drive may be necessary. In contrast to single-level stacker cranes (shuttle vehicles), multi-level stacker cranes (such as a stacker crane with lift mast) usually use an overhead telescopic drive. Both applications can be covered with the present telescopic arm. Is due to the conditions of use in the warehouse a high bending stiffness of the center table in
    Side direction in the foreground and losses in the torsional rigidity can be accepted, it is possible to achieve this by an upwardly open stiffening profile. A multiply bent upper edge of the stiffening profile causes a material accumulation with a large distance to the neutral fiber and thus high rigidity in the right direction.
    Such a construction designed in the production of the main parts of the center table can be dispensed with machining methods. The preparation of e.g. Canted steel sheets produced by laser cutting allow easy adaptability without having to procure new extrusion dies.
    The elimination of aluminum extruded profiles and the center table, as in the case of the upper table, has the advantage that the profiles do not deform in an arc shape when the temperature fluctuates. In addition, the attachment of the belt deflectors on the center table is simplified by a plug connection.
    Since the forces introduced via the gripper finger and the gripper finger bearing into the telescopic arm are guided directly into the guide part of the linear guide, a significantly lighter and space-saving design results compared to the prior art. Since the telescopic arm with the gripper fingers is the central component of an entire automated warehouse, this has an impact on the entire storage system. A smaller width of the telescopic arm in the x direction and a smaller height in the y direction makes it possible to store the goods in the warehouse with a smaller distance from one another. This means that the advantage of the smaller footprint of the telescopic arm multiplied by the number of parking spaces. An optimization of a few millimeters at the telescope thus brings a great improvement in storage density.
    The introduced without detour from the gripper bearing in the guide part of the linear guide force reduces the stress on the profile of the upper table. Due to the loss of local bending forces in the area of the gripper finger bearing, the profile of the upper table can be made of a thin sheet. This significantly reduces the weight of the telescopic arm. This not only affects the load handling equipment but also the entire storage and retrieval system. A storage and retrieval unit with a mast mounted on a landing gear on which the lift cage with load-receiving means that can move in the vertical direction (y-direction) can have a weight of several tons. Since the weight of the complete storage and retrieval system is largely defined by the mass of the movable in the y direction Hubkorbes, a weight saving on the telescopic arm has a great impact. A relatively lighter telescopic arm enables the weight of the entire storage and retrieval system to be designed to make the same ratio easier. Thus, the storage and retrieval device with smaller designed drives higher accelerations, travel speeds and thus achieve a higher logistical throughput while maintaining low energy consumption.
    Due to the solution designed in this way, no location with increased material thickness must be provided on the profile of the upper table, where the gripper finger bearing can be screwed. Therefore, this can be made of a bent part of thin sheet, which has the same material thickness at each point. It is therefore not necessary to use as an upper table profile, for example, an extruded profile having a thicker material thickness at the screw points. The fact that an extruded profile can be produced economically only from aluminum would mean that the material used can only be aluminum. However, the present invention makes it possible to use a thin sheet of steel with simultaneous advantages in terms of weight, space and rigidity. This makes it possible to use another significant advantage: Due to the demands on the guide parts with respect to wear and strength, these are made of a steel material. Combining a steel linear guide with an aluminum profile would result in a disadvantageous bimetallic construction which deforms as the temperature changes. This is particularly important in applications in frozen food warehouses, where the temperature difference between final assembly of the telescopic arm and the later place of use in the frozen storage can be 50 ° C and more. The different temperature expansions of steel and aluminum affect the entire length of the telescopic parts and deform the individual tables arcuately. With an extension of several meters, the effect increases whereby the furthest extending end of the upper table can be deformed up to an upper table width in the x direction. In addition to collisions with the goods stored on the shelf, this would also cause disturbances of the linear guide. The present invention now makes it possible without disadvantages that the top table profile, like the linear guide, can also be made of steel, whereby deformation due to different coefficients of thermal expansion is avoided.
    The use of the telescopic arm described varies greatly. Depending on how many goods have to be stored on the shelf one behind the other in the z direction, the necessary extension path of the telescopic arm also changes. Therefore, the telescopic arms must be adapted to the particular application. Depending on the requirements in terms of weight and dimensions of the payload to be funded, the number of necessary gripper fingers, existing space between the goods on the shelf and other parameters, the telescopic arms must be changed according to requirements. Whether the telescopic arm is mounted on a multi-level or single-level stacker crane also influences the required design.
    In the present invention, since the upper table can be made of a steel sheet edge part, there is no special tool, e.g. an extrusion tool necessary. Therefore, a telescopic arm adapted to the requirements of the respective project can be produced without expensive tool changes.
    Due to the design of the upper table made of e.g. Thin-sheet profile produced by means of laser cutting and edges, it is in contrast to an extruded profile easily possible wherever there is material auszusparen where this is not necessarily needed. Thus, the upper table ideally only at the ends of the belt attachment points for the overdrive belt on the full height, which additional weight is saved. If, in certain applications, it is necessary to prevent the overstrips from contact with e.g. To protect particularly bulky goods, this can easily be accomplished via an additional patch light railing.
    The belt attachment point also combines several functions. In addition to clamping the overdrive belt, the described solution allows over the belt protruding contours such as e.g. Clamps or screws to avoid. It is thus avoided that seen in the x direction to the side where the center table is moved past the upper table, on the free-running Riementrum projecting parts. As a result, the outer dimensions of the telescopic arm can be further reduced. Furthermore, it is possible in the tension members of the belt (preferably steel strands) to initiate electric power for the information and energy transmission from the undercounter to the upper table.
    Detailed Description: In Fig. 1 a load handling means 4 is shown as used for storage and retrieval of goods 74 e.g. used in storage shelves. Such a load-bearing means 4 can be used on various types of storage and retrieval machines, such as storage and retrieval machines. Storage and retrieval machines with mast or shuttle vehicles are used. To take over goods 74 e.g. From a shelf extend the telescopic arms 1 with previously brought to a vertical position gripping fingers 36 in the z direction. Thereafter, the gripping fingers 36 are pivoted so that they engage behind the product 74 in a form-fitting manner. By moving back the telescopic arms 1 in the opposite direction only the goods 74 can be pulled onto the platform 5. The platform 5 can for example also be designed as a one-piece or multi-part conveyor in order to increase the throughput capacity or to separate a plurality of goods 74 located on the load receiving means 4. The delivery of the product 74 works in the opposite direction.
    The telescopic arm 1 according to FIGS. 2 to 13 has a sub-table formed from sheet-metal profiles 3. Preferably, this consists of a box section wherein the screws for fixing the guide member 41 of the linear guide 40 can simultaneously serve to connect the sheet metal profiles 3. As can be seen in particular Fig. 3, the lower table 2 is also the mounting base for the telescopic drive 57. This drives via a drive wheel 58 to the drive chain 60, which runs over the Kettenumlenkungen 59 and engages the rack 15.
    From the lower table 2, the middle table 10 is received via the linear guide 40, which is displaceable in the z direction 72 starting from the basic position in both directions. In Fig. 8, the telescopic arm 1 is shown in an extended position. As shown in Fig. 3, the center table 10 is in
    Essentially from a rack 15 forming sheet metal profile 12 together which receives at its central web 13, the two guide members 41 and is stiffened with at least one transverse web 14.
    The two guide members 41 are bolted together by screws 42 through the central web 13 of the sheet metal profile 12 and the stiffening profile 16.
    From the center table 10, in turn, the upper table 30 is received via a linear guide 40 which is also displaceable relative to the center table 10 in the z direction 72. The upper table 30 consists essentially of the guide part 41 of the upper table 30 and the gripper finger bearings 33 and clamped between these parts with screws 35 profile web 32 of the sheet metal profile 31. In the areas (seen in the z-direction 72) between the gripping finger bearings 33 is the sheet metal profile 31 bolted directly to the guide member 41. The gripping finger bearing 33 receives the pivoting about the axis 37 of the gripper finger 36 gripping fingers 36 to engage behind the goods 74 and can move. The drive of the gripper fingers 36 is preferably carried out with small electric motors, which are not shown separately for the sake of clarity.
    Fig. 2 shows a telescopic arm 1 in an exemplary embodiment. In order to influence the torsional rigidity of the upper table 30 favorably, the cover profile 38 is screwed with screws 39 in two rows of screws with the sheet-metal profile 31 of the upper table 30. The screws 39 of the upper row of screws are screwed by the profile 31 in the guide member 41 into it. The screws 39 of the lower row of screws also connect the cover profile 38 with the sheet metal profile 31 of the upper table 30. The resultant closed cross-section causes only small deformations occur in torsional load. In order to obtain a surface without projecting screw heads, the cover profile 38 is preferably provided with impressions to the screws 39 to sink.
    The sectional view Fig. 3 shows the attachment of the mounting boss 34 of the gripping finger bearing 33 through the sheet metal profile 31 of the upper table 30 in the upper table 30 associated guide member 41 of the linear guide 40 by means of screws 35. Instead of screws 35, however, for example, rivets or other fasteners are possible. Furthermore, the structure of the center table 10 can be seen. The central web 13 of the rack 15 forming sheet metal profile 12 is received between the two the middle table 10 associated guide members 41. On both sides of the sheet metal profile 12 stiffening profiles 16 are arranged which have a transverse web 14 and the profile webs 21 are clamped between the sheet metal profile 12 and the guide members 41. Above the linear guide 40, the two stiffening profiles 16, with the longitudinal edge web 17 form a closed torsionssteifes profile. The connection of the longitudinal edge webs 17 is preferably carried out by means of connecting plates 18 and screws 19th
    FIG. 4 illustrates the belt drive realized with the overdrive belt 50 which transmits the movement from the center table 10 to the upper table 30. In order to be able to recognize the course of the overdrive belts 50 in the illustration, the individual tables 2, 10, 30 are shown spaced apart in the x direction 70 and the telescopic arm 1 is shown in one of the two extended positions. For the sake of clarity, a representation of the other extended position has been dispensed with. In order to ensure a large extension path 73, the telescopic arm 1 shown has two overdrive belts 50. The one overdrive belt 50 is fastened with its end to the left belt attachment point 53 of the upper table 30 and guided via the right belt deflection 51 of the center table 10 to the left belt attachment point 54 of the undertable 2 and attached there. The other Übertriebsriemen 50 is fixed with its end to the right belt attachment point 53 of the upper table 30 and guided over the left belt deflection 51 of the center table 10 to the right belt attachment point 54 of the lower table 2 and fixed there. So that the two overdrive belts 50 do not touch, they are arranged offset in the y-direction 71. As shown in FIG. 13, a telescopic arm 1 can also be realized only with an endlessly circulating overdrive belt 50, but the possible extension path 73 is then smaller.
    In Fig. 5 a partially extended telescopic arm 1 is spatially shown with telescopic drive 57 arranged above. The rack 15 formed by the metal profile 11 of the center table 10 engages in the drive chain 60, whereby the center table 10 can be moved in the longitudinal direction. The overshoot on the upper table 30 via the Übertriebsriemen 50. The use of a chain in the telescopic drive 57 and a belt as Übertriebsriemen 50 is by no means mandatory. When telescopic drive 57, for example, a toothed belt is conceivable, which engages in a correspondingly shaped rack 15. Likewise, instead of the overdrive belts 50, other forms of tension members such as e.g. Bands or chains possible. In Fig. 5 further connection of the two longitudinal edge webs 17 of the stiffening profiles 16 is shown which pass through the central web 13 of the sheet metal profile 11. This penetrating connection is configured such that the sheet-metal profile 11 has recesses through which the longitudinal edge webs 17 are connected. Preferably, this connection is made with connecting plates 18 and screws 19.
    FIG. 6 shows a detail view of the partially extended telescopic arm 1 from the rear and serves as a source for the following sectional view. Furthermore, this view is used to better illustrate the two superimposed tracks of the overdrive belt 50th
    In Fig. 7, the belt stop 53 of the upper table 30 is shown. The thus designed stop point avoids in the direction of the center table 10 on the contour of the overdrive belt 50 protruding parts, whereby the simple structure and the small width of the telescopic arm 1 are made possible. By means of the base plate 55 and the cover plate 56 of the belt attachment point 53, the overdrive belt 50 is led away from the main axis of the belt passage through an opening in the sheet metal profile 31 of the upper table 30 and clamped there. Such a construction thus makes it possible to clamp the belt end between two plates, without having to accept a projecting contour. In this sectional view of the attachment of the belt deflection 51 is further shown on the center table 10. A provided in the axis 52 of the belt 51 deflection groove with the same width as the plate thickness of the sheet metal profile 11, 12 of the center table 10, allows the belt deflection 51 easy aufzustecken on the metal profile 11, 12. The tension of the Übertriebriemens 50 prevents loosening of this connector. If necessary, additional provisions such as e.g. Gluing or pressing are applied.
    Fig. 8 illustrates an example embodiment of the telescopic arm 1 in one of the two extended positions. In order to ensure a wide range of application of the telescopic arm 1, the telescopic arm 1 can extend in both directions. For clarity, only one extended position is shown.
    Fig. 9 illustrates an example embodiment of the telescopic arm 1 in the basic position. Furthermore, this view serves as a source for the following sectional view.
    FIG. 10 shows an alternative embodiment of the stiffening profiles 20 of the center table. Instead of connecting the stiffening profiles 20 via an upper longitudinal edge web 17 to one another, the connection is made by spacers 22 and screws 23. The heads of the screws are preferably recessed by embossing in the stiffening profiles 20 in order to achieve a compact design. Such a shaped design makes it possible in the upper region of the stiffening profiles 20 to bend over the sheet several times, whereby a large accumulation of material far away from the neutral fiber and consequently a good flexural rigidity in the x direction 70 is formed. Due to the upwardly open cross-section, this version can not be used where high torsional stiffness is required.
    The linear guides 40 shown in particular in Fig. 10 can be performed variously. There are different versions available on the market, where the main point is the interface to the adjacent construction and a sufficient service life. Linear guides 40 can be designed as sliding bearings or can be used with rolling elements or rollers. Since the forces occurring on the linear guide 40 of the center table 10 are generally higher than those in the linear guide 40 of the upper table 30, sizes of different sizes can be used in a telescopic arm 1. It is advantageous in certain applications, the linear guide 40 of the center table 10 to execute greater than that of the upper table 30. For the sake of clarity, the linear guides 40 are shown simplified. In the case of particularly long extension paths, it may be advantageous to carry out the telescopic arm 1 with two center tables 10, which are displaceable relative to one another, instead of with a center table 10.
    As shown in Fig. 11 results from the proposed solution, a flexible kit for the center table 10. The present in each expression linear guide 40 with the two guide members 41 can either the sheet metal profile 11 in the embodiment rack 15 above or the sheet metal profile 12 in the embodiment Pick up rack 15 at the bottom. Depending on the extension length and the existing bending and torsion moments, either one or two stiffening profiles 16, 20 can now be combined. As shown in Fig. 3 and Fig. 5, the stiffening profiles 16, 20 are designed such that they can be used for both the rack 15 down variant and for variant rack 15 above. 5 enforce the longitudinal edge webs 17 and connecting plates 18, the rack 15. In very short telescopic arms 1 can be dispensed with an additional stiffening profile 16, 20 entirely. A cross bar 14 on the sheet metal profile can provide a minimum amount of bending stiffness in this case, but in some cases, this can also be omitted. The transverse webs 14 on the sheet metal profile 11, 12 and the stiffening profile 16, 20 must by no means run at right angles to the central web 13. It may be advantageous for the construction if they are arranged obliquely. Depending on the application condition, the telescopic drive 57 can be arranged either above or below. Fig. 5 shows an application with telescopic drive 57 above and Fig. 3 shows an application with telescopic drive 57 below as it is used more in single-level stacker cranes.
    Fig. 12 and Fig. 13 shows a telescopic arm 1 with the expression telescopic drive 57 below and with only one Übertriebsriemen 50. This corresponds to the extension path 73 of the upper table 30 per direction maximum of the basic length of the telescopic arm 1. Dashed line is the expression with telescopic drive 57 above which can be realized with the same or only slightly modified components. The design of the undertable 2 as a box profile is by no means compulsory and may e.g. also be designed as an open profile or solid material.
