Definitions
- the field of the invention is that of logistics.
- the invention relates to a load routing system without sequencing, between a plurality of storage units and a plurality of preparation stations.
- the storage units correspond, for example, to the different aisle exits of an automated storage / retrieval warehouse.
- sequencing (or “supply of sequenced loads”) is meant the provision, under a delivery constraint, of at least one sequence comprising charges in a desired order.
- each preparation station is equipped for this purpose with a buffer storage and load sequencing system, for example one of the types described in the applications patent FR1563151 of December 22, 2015 and FRl 654863 of May 30, 2016.
- the present invention can be applied to any type of preparation station, and in particular but not exclusively: - order picking stations (also known as “picking stations”), by taking products from storage containers (also called “source charges”): an operator (or robot) receives a list of samples (on paper , on a screen of a terminal, in voice form, in the form of a computer mission (in the case of the robot), etc.), indicating for each package to be shipped (also called “shipping container” or “target load” ), the quantity of each type of product that must be collected in storage containers and grouped in the package to be shipped; and
- - palletizing stations for storage containers also called “source loads” containing products themselves: an operator (or robot) receives a list of samples (on paper, on a screen of a terminal, in voice form) , in the form of a computer mission (in the case of the robot), etc.) indicating to him, for each pallet to be shipped (also called “shipping container” or “target load”), the quantity of each type of storage container (eg cartons) it must collect and unload on the pallet to be shipped.
- source loads also called “source loads”
- FIG. 1 a top view of an exemplary configuration known for an automated order preparation system comprising:
- An automated storage / retrieval warehouse 7 comprising several (two in this example) assemblies each formed of an aisle 7a, 7a 'serving on both sides a storage shelf 7b, 7c, 7b', 7c 'with several tiered storage levels;
- a set of conveyors bringing the source charges from the automated warehouse 7 to preparation stations, and vice versa there are:
- a plurality of picking stations 10a to 10f each occupied by an operator 1a and extending perpendicularly to the conveyors referenced 8 and 8 ';
- a control system (also called “control unit”), which is a central management computer system responsible for controlling the entire system (automated storage / retrieval warehouse 7, set of conveyors 6, 6 ' , 8, 8 ', 9a, 9a', 9b and 9b ', and preparation stations 10a to 10f).
- the control system also manages the list of commands associated with each shipping container (target load) and therefore the order of the order lines forming this list, depending on the location of the storage containers (source loads) in the container.
- automated warehouse 7 the availability of the carts and elevators of the automated warehouse 7, as well as the product needs of the various shipping containers to be prepared which succeed one another at the preparation station. This is to optimize all travel and preparation times of shipping containers and ensure synchronization between the arrival, at the preparation station, of a shipping container and the corresponding storage containers ( ie containing the products indicated in the order list associated with this storage container).
- each preparation station comprises two conveyor circuits: a first conveyor circuit for the storage containers, formed of two horizontal columns of conveyors: one (forward column 3) for moving the conveyors; storage containers from the third subset of conveyors 8 to the operator la, and the other (return column 2) for the reverse movement; and a second conveyor circuit for the shipping containers, consisting of two horizontal conveyor columns: one (forward column 4) for moving the shipping containers from the third conveyor subassembly 8 to the next operator la, and the other (return column 5) for the reverse movement.
- a buffer storage function (also called “accumulation function") of a predetermined quantity of containers upstream of the operator (or the automaton) is performed, in each of the first and second circuits, by the forward column 3 and 4 (composed of conventional horizontal conveyors).
- a storage container thus carries out the following route: it is taken by a truck in the automated warehouse 7, then conveyed successively by one of the conveyors 9a and 9a '(as it arrives from the aisle 7a or 7a') , then by the conveyors 6 and 8, and finally by the conveyors of the column to go 3, to be presented to the operator.
- the storage container performs the reverse course: it is conveyed by the conveyors of the return column 2, then by the conveyors 8 'and 6', and finally by the one of the conveyors 9b and 9b '(as it returns to the aisle 7a or 7a'), before being returned to the automated warehouse 7 by a carriage.
- the containers (source charges and target charges) must be presented to the operator in a desired order forming at least one specified sequence.
- this order of arrival is predetermined by the control system (that is to say, determined for each container, before the container reaches the preparation station) and, if necessary, recalculated during routing containers from the output of the automated warehouse 7 to the preparation station (for example to account for a failure of a system element).
- a first level of sequencing is achieved by depositing on each of the conveyors 9a and 9a 'pre-sequenced loads.
- the charges deposited on the conveyor 9a are in an order consistent with the desired final order, and the charges deposited on the conveyor 9a 'are also in a order consistent with the desired final order.
- a second level of sequencing is performed by depositing in the desired final order, on the conveyor 6, the charges coming from the conveyors 9a and 9a '.
- the rank charges 1, 2, 4 and 5 are stored in the aisle 7a they are deposited in this order on the conveyor 9a and if the rank charges 3 and 6 are stored. in the aisle 7a 'they are deposited in this order on the conveyor 9a'; then the seven charges are deposited on the conveyor 6 in ascending order (from 1 to 7) of their ranks.
- the sequencing in order to relax the constraints on the automated warehouse 7, it is assumed that the containers do not leave the automated warehouse 7 in the desired order (that is to say the order in which they must be presented to the operator). It is therefore necessary to perform two functions, one for routing and one for sequencing the containers, between the automated warehouse 7 and the preparation station where the operator is located.
- these routing and sequencing functions are performed as follows, for a given preparation station: the storage containers circulate on a loop (also called “carousel") formed by the conveyors 6, 8, 8 'and 6', and when the next storage container of the sequence expected by the given preparation station is in front of the forward column 3 of this given preparation station, this storage container is transferred to the conveyors of the column go 3.
- a loop also called "carousel”
- a storage container shall circle the loop if it is in front of the forward column 3 of the given preparation station when at least one of the storage containers preceding it in the sequence has not still been transferred to the first column 3 of the given preparation station. This process is performed for each of the storage containers of the sequence expected by the given preparation station.
- the aforementioned principle of the loop (carousel) is also used to perform the only function of conveying loads (in FIG. 1, between on the one hand the input conveyors 9b, 9b ' 9a, 9a 'of the aisles 7a, 7a' of the automated warehouse 7 and secondly the inlet conveyors 3, 4 / output 2, 5 of the preparation stations 10a to 10f).
- the loop (carousel) is used only for the routing of loads.
- the storage containers circulate on the loop (carousel) formed by the conveyors 6, 8, 8 'and 6', and as soon as a storage container for the given preparation position is in front of the forward column 3 of this preparation station, it is transferred to this forward column 3.
- certain sections of the loop are used by all the loads: on the go, the section located between the point of connection (on the conveyor 6 of the loop) of the exit conveyor 9a of the aisle 7a and the point connection (on the conveyor 8 of the loop) of the input conveyor 3 or 4 of the preparation station 10a; at the return, the section situated between the point of connection (on the conveyor 8 'of the loop) of the output conveyor 2 or 5 of the preparation station 10a and the point of connection (on the conveyor 6' of the loop) of the conveyor entrance 9b of alley 7a.
- a load In the least favorable case, that is to say to go the longest way (go or return) between one of the aisles 7a, 7a 'of the automated warehouse 7 and one of the preparation stations 10a to 10f, a load must pass in front of the other aisle (s) of Automated Store 7 and the other prep station (s).
- a load In the example of FIG. 1, in order to traverse the longest path, between the aisle 7a 'and the preparation station 10f, a load must pass in front of the other aisle 7a and the other preparation stations 10a to 10e. .
- a load In the example of FIG. 1, in order to traverse the longest path, between the aisle 7a 'and the preparation station 10f, a load must pass in front of the other aisle 7a and the other preparation stations 10a to 10e. .
- a load In the longest return path, between the preparation station 10f and the aisle 7a, a load must pass in front of the other preparation stations 10a to 10e and in front of the other aisle 7a.
- the invention in at least one embodiment, is intended in particular to overcome these various disadvantages of the state of the art.
