Definitions

  • the invention relates to a rack storage system and method for operating a rack storage system, as well as a rack storage system, trolley and auxiliary unit for this, as described in claims 1, 11, 13 and 16.
  • Previously known automatic shelving systems mostly have an aisle in which a storage and retrieval device, lifting beam device, or shuttle vehicle moves with its own load handling device in order to be able to store, retrieve and relocate conveyed goods in the shelving system.
  • the shelving systems are usually complex, expensive and must be coordinated in great detail with the goods to be conveyed during the project planning phase.
  • a not inconsiderable amount of space is required between the individual containers in order to create free space for the load handling device, which is transported by means of a telescope, finger technology, or carriage, the receiving device or the goods from the shelf to the driving lane. This can then be transported to a loading and/or unloading station.
  • a storage system for containers is known from DE102016125786A1 and WO2016020397A1, in which a large number of containers can be stacked one on top of the other in the form of a stack of containers and a large number of stacks of containers can be arranged next to one another.
  • the rack storage system comprises a number of vertical shafts, with a shaft or rack system being formed from four delimiting elements.
  • a container is stored and removed from the underside of the container stack via a carriage, the carriage being equipped with a lifting device and lifting the container into a first position in which the container stack is held by means of aids.
  • the disadvantage here is that when a container is stored, all of the containers in the shelf system have to be lifted up, since all of the containers are on top of one another within a shelf system.
  • the lifting device in the transfer carriage must therefore be able to lift a great deal, so that the lifting mechanism in such a shelving system must be designed for the load of the entire stack.
  • the tool used to hold the containers must also be dimensioned accordingly.
  • a shelf storage system or picking system in which two pairs of posts, which are each connected to two different shelves, delimit a traffic route.
  • a trolley with automatic guidance can take an object or container of an order from at least one of the shelving systems, the trolley being equipped with climbing means capable of moving upwards along the limiting means.
  • a roller chain is attached to each limiting device so that a toothed wheel, the climbing device, engages with the roller chain and the carriage can thus be moved vertically. Storage, retrieval and rearrangement is carried out by the trolley in a horizontal direction in the shelving system.
  • Dematic's patent DE102019111709B4 describes a complex solution for storing stored goods on a shelf, with at least 2 lifting units in the free space of the shelf uprights being synchronized with one another and having to work together in parallel in order to be able to store, remove or relocate a load on the shelf .
  • the number of drives required and the complexity of the control technology severely limits the cost-effectiveness.
  • An intermediate carrier or a specially developed storage device, such as the Autostore solution, is required for storing goods.
  • the object of the invention is to create a method for operating a rack storage system, as well as a rack storage system, trolley and auxiliary unit for this purpose, in which the disadvantages mentioned above are eliminated on the one hand and the focus is placed on the economy and performance of the storage system on the other.
  • the goal is to develop a storage system that reduces the free space in the rack to a minimum, keeps the degrees of freedom in the construction of the rack system as free as possible in all dimensions and eliminates the limitation of the height of the rack system.
  • the height of the shelving systems should be independent of each other and may have jumps in height in order to be able to adapt seamlessly to the building geometry.
  • the Performance can be kept flexible and scalable and there is the possibility of further increasing the system performance by rearranging at any height within the shelving system.
  • Another feature of the invention is the use of universal storage means, which remain largely unrestricted in terms of length, width and height.
  • each rack system (4.4a-4h) defines and assigns several storage locations (15) for the storage means (3, 30, 3b, 3c), the Storage of a means of storage (3, 30, 3b, 3c) or goods is carried out in a vertically descending manner, in particular downwards from the next free top storage location (15), by the carriage moving vertically upwards and the storage means or goods above the carriage is stored in the shelving system, in particular only by a vertical movement of the transfer carriage
  • the basic unit itself is coupled into the shelving system in order to store the storage means or goods vertically. It is only necessary for the transfer carriage to stop in the vertical movement at a predetermined storage location and for the storage means or the goods to be deposited at the storage location by means of a vertical downward movement.
  • the height of the storage locations can be freely divided, so that different storage media or goods can be stored.
  • Pre-assembled holding means, in particular holding flaps can preferably be freely defined for different conveyed goods heights, with a storage means or goods also being able to extend over one or more holding means arranged one above the other.
  • the storage locations can be automatically recognized by the transfer carriage, in that the holding means can be recognized and correspondingly read out or evaluated, for example via magnets, sensors or RFID chips.
  • a design is also advantageous in which the carriage is formed from a basic unit and a lifting unit, the freely movable carriage (2) having the lifting unit (10) positioned below the shelving system (4.4a-4h) with the storage means ( 3, 30, 3b, 3c) into a coupling location (7a), whereupon the lifting unit (10) autonomously transports and deposits the storage means (3, 30, 3b, 3c) to the next free top storage location (15).
  • the lifting unit with its drive elements in particular gear wheels, latches or is coupled into corresponding aids in the delimiting elements in the coupling station.
  • the lifting units can engage in the racking system in a form-fitting manner, which is why no external path measuring systems have to be used, which in turn contributes significantly to increasing the cost-effectiveness of the entire system.
  • the positive drive unit increases the safety of the system because the lifting unit cannot fall to the ground, as could be the case with a drive using friction or clamping force.
  • each storage location is assigned at least one, preferably four, holding means on the delimiting elements, which are activated by the lifting unit when a storage means is positioned.
  • This ensures that the storage means do not have to be stacked on top of each other, but can be placed directly in the shelving system.
  • This enables very high overall heights as the Loads are diverted into the shelving system and not concentrated on the lowest container.
  • this measure lowers the requirement for the evenness of the ground on which the system is erected, since inclinations are not added up and therefore do not lead to situations in which container stacks become unstable and tip over in the shaft.
  • the possible maximum height is not limited by the floor or container and a multiple of the maximum height of the AutoStore system can be achieved.
  • the storage of the storage means by means of holding means attached to the shelf allows that almost any storage means used in the industry can be stored in the system and does not have to resort to specially developed containers, as is the case with AutoStore.
  • the customer can thus continue to use his existing means of storage and is not dependent on a single supplier since means of transport belong to general commodities in the industry and are widely available.
  • the vertical division of the containers can be designed as desired by the type of storage using the holding means on the shelf.
  • the software can carry out intelligent storage management for the different heights of the storage means, so that even the lowest and highest containers can be stored in a space-saving way in a rack system.
  • the transfer carriage in particular the basic unit, picks up another lifting unit in another racking system after the lifting unit has been positioned and set down in one racking system, or waits for the lifted unit that has been set down, or a newly loaded lifting unit from a loading and/or loading station collection station and picks it up or takes over a storage medium directly from the lifting unit.
  • the measures in which the storage means to be relocated to free rack systems in the lowest free storage levels of one or more rack systems are temporarily stored in order to relocate storage means for removing or rearranging a storage means stored above the shelving system are advantageous. As a result, it is possible to change the container sequence easily. Sorting the containers according to the FIFO (first in first out) principle can thus be mapped quickly and easily. In addition, this concept enables the lower free rack systems to be used for the consolidation or sequencing of customer orders, which in turn replaces classic consolidation buffers such as flow beam devices, fever or similar, or large conveyor technology loops.
  • the transfer carriage in particular a control of the base unit, the lifting unit and the determination of the storage space of a storage medium to be stored and for removing a storage medium from a defined storage space of a Storage software takes place or is managed.
  • This ensures that the goods are organized based on the frequency of their stock movements within the warehouse in order to be able to provide quick access to frequently used goods.
  • the entire warehouse structure is to be continuously monitored by an AI (artificial intelligence) in order to adapt the warehouse structure precisely to the needs of the customer, to make predictions and to reorganize the warehouse in advance or to plan goods that have a near best-before date for picking in advance.
  • AI artificial intelligence
  • the storage software can fully automatically open a maintenance aisle with the remaining functional traversing and lifting units in order to create an aisle so that the fault can be corrected manually.
  • Measures are advantageous in which, in order to remove a storage means, the storage means is lifted by the lifting unit or carriage, as a result of which the holding means return to the resting position, in particular are folded in, whereupon the storage means is then transported downwards by the lifting unit or the carriage .
  • This ensures that there are no interfering contours within the shelving system and the lifting unit can move within the shelving system without any problems.
  • the resetting ensures that the transfer of containers from one lifting unit to a lifting unit waiting in the adjacent rack system is possible at any position.
  • the transfer carriage in particular the base unit, moves freely between the rack systems below the coupling location, in particular can switch from one rack system to a rack system arranged next to it.
  • This makes it possible for each shelving system to be reached from a basic unit either with or without a lifting unit, so that each basic unit in each shelving system can put a lifting unit on and off, and each basic unit has direct access to the lowest container or can take containers from a lifting unit.
  • a rack storage system comprising at least one or a large number of rack systems arranged next to one another, with a rack system being formed from at least two, preferably four, boundary elements, in which a plurality of storage means can be stacked one on top of the other, with the storage and removal of a storage means of on the underside of the shelving system, whereby the storage means can be stacked one on top of the other within the shelving system, in which defined storage locations are arranged one above the other within a shelving system, with each storage location being assigned at least one, preferably four, holding means which are transported by the storage means or goods Mechanics, in particular the lifting unit, can be activated in order to be moved from a rest position to a receiving position so that the storage means or goods can be stored.
  • the advantage here is that the storage means are not directly on top of each other and the lowermost storage means consequently does not have to carry the entire load of all storage means and their contents.
  • the overall height of the shelving system is therefore no longer restricted due to the maximum permissible load of the lowest storage means.
  • a further advantage lies in the fact that the holding means for storing a storage means can be activated by a lifting unit that can be moved independently in the shelving system. This ensures that no fixed shelf divisions are provided in the shelving system, but rather the holding means for storing the storage means can be selected dynamically on the basis of the load height to be stored. This means that an extremely high storage density is achieved because the space between two storage items on the shelf is always kept to a minimum.
  • a traversing carriage for use in rack storage and for carrying out the method for operating rack storage comprising at least one base unit for transporting a storage medium, the base unit having a lifting device, in particular an initial lifting unit, for receiving a storage medium or goods , And is supplied with electrical energy from an integrated energy source, in particular a rechargeable battery, for the ferry operation, with software, in particular control software, for moving the basic unit in a controller is integrated, in which another independently working and detachable lifting unit for receiving the storage means is arranged on the base unit, wherein the lifting unit can be set down via an initial lifting unit below a shelf storage at a coupling point for a vertical movement within the shelf system or the base unit for coupling is designed with a shelf store, in particular a shelf system, for vertically descending filling with storage means or goods within a shelf system.
  • the advantage here is that the separation of the traversing carriage into two independently operating systems, in particular a base unit and a lifting unit, means that these can be produced inexpensively.
  • Another important advantage is that an unequal number of lifting units and basic units can be used in a rack storage system. In particular, more lifting units are used than basic units in order to significantly speed up storage and removal.
  • a configuration is advantageous in which the base unit is designed for the preferably contact-free charging of the lifting unit with electrical energy when the lifting unit is being transported. The result of this is that wear-sensitive charging contacts can be saved. Separate charging of the lifting unit and the base unit also makes sense for higher performances in the system.
  • a lifting unit for use with a traversing carriage, in particular a base unit, and for use in rack storage and for carrying out the method for operating a rack storage system
  • the lifting unit has at least one base body with at least one, preferably comprises four drive elements for a vertical direction of movement and an energy source integrated in the base body for supplying the drive elements and a controller for autonomous movement is arranged within a shelving system, with the base body on one side for receiving a storage medium and on the opposite side for transport with a base unit a carriage is formed.
  • the advantage here is that the integrated energy stores through the drive elements when relocating or vertical travel down again Recuperation charged and thus the time between charging processes can be extended. This contributes significantly to the energy efficiency of the overall system.
  • an embodiment is advantageous in which a conveying means for transferring a storage means to another lifting unit is arranged on the base body for receiving the storage means. This ensures that the storage means is transferred within the shelf from a lifting unit to a waiting lifting unit in the delimiting shelf system at any point. This results in a dramatic increase in performance when many storage items need to be moved to other shelving systems in order to remove a top-level storage item from the system.
