Definitions
- the present invention relates to a picking system that includes an automated warehouse that stores multiple mounting bodies, each of which has multiple items mounted thereon, multiple work areas in which picking work is performed to remove items of the type and number specified by order information from the mounting bodies released from the automated warehouse based on order information that specifies the type and number of items required for each shipping destination, a transport system that transports the mounting bodies between the automated warehouse and the multiple work areas, and a control system that controls the automated warehouse and the transport system.
- a carrier carrying items of a type specified in order information is transported from an automated warehouse to a work area. Then, in the work area, picking work is performed to extract the type and number of items specified in the order information. Multiple picking tasks that occur as tasks in the picking system are assigned to multiple work areas, respectively.
- An example of such a picking system is disclosed in JP 2015-199562 A.
- the automated warehouse 1 is equipped with a storage shelf that stores the objects 5, and an in-shelf transport device that transports the objects 5 within the automated warehouse 1.
- the in-shelf transport device include a stacker crane, a lifter, a transport cart arranged on each level of the storage shelf, and a conveyor.
- the in-shelf transport device constitutes part of the transport system T.
- the picking system 100 is equipped with multiple such automated warehouses 1. Note that if the automated warehouse 1 is equipped with a conveyor as the in-shelf transport device, the automated warehouse 1 may be configured to store the objects 5 on the conveyor. In this case, the automated warehouse 1 may be configured not to include a stacker crane or a transport cart.
- the transport system T includes a conveyor Ta.
- the transport path of the object 5 by the conveyor Ta is formed to connect multiple automated warehouses 1 and multiple work areas 2.
- the object 5 taken out from one of the multiple automated warehouses 1 is transported to one of the multiple work areas 2 through the transport path of the conveyor Ta.
- the object 5 from which the required item W has been picked out by picking work in the work area 2 is transported to one of the multiple automated warehouses 1 through the transport path of the conveyor Ta and stored.
- the transport system T may include other types of transport devices such as an unmanned transport vehicle instead of or in addition to the conveyor Ta.
- the transport system T includes an intra-shelf transport device that transports the object 5 within the automated warehouse 1.
- the control system 3 is configured to perform inventory management of the items W in the automated warehouse 1.
- the control system 3 is configured to manage at least the type and number of items W placed on each of the placement bodies 5 stored in the automated warehouse 1.
- the control system 3 can be configured using multiple pieces of hardware and multiple pieces of software.
- the control system 3 includes, for example, a processor such as a microcomputer, and peripheral circuits such as memory. Each function is realized by the cooperation of this hardware with a program executed on a processor such as a computer.
- the picking work is performed based on the order information In.
- the picking work multiple or a single item W specified in the order information In is collected.
- the order information In is generated for each shipping destination. Therefore, the picking work can be said to be the work of collecting the items W requested for each shipping destination.
- the order information In specifies three items W of type A (hereinafter, sometimes referred to as "item A”), two items W of type B (hereinafter, sometimes referred to as “item B”), and one item W of type C (hereinafter, sometimes referred to as "item C").
- each mounting body 5 is configured to mount a single type of item W, and a mounting body 5 for mounting three or more items A, a mounting body 5 for mounting two or more items B, and a mounting body 5 for mounting one or more items C are transported to the work area 2. Then, in the picking work in the work area 2, three items A, two items B, and one item C are collected in a shipping container 6.
- the picking work may be performed by a worker, or may be performed unmanned by a picking robot or the like. Alternatively, it may be performed by both a worker and a picking robot.
- the batch jobs include a set number of picking jobs related to the order information In. That is, the batch jobs include a set number of picking jobs.
- the "set number" is not determined uniformly. As shown in FIG. 4, one batch job may include two picking jobs, three picking jobs, or four picking jobs. That is, in the example shown in FIG. 4, the "set number" is 2 to 4.
- the "set number” may be determined flexibly as appropriate, or may be a constant that does not change.
- control system 3 is configured to execute an index calculation process to calculate a similarity index Ex that indicates the degree to which each of the multiple order information pieces is similar to one another.
- the control system 3 assigns a type value Va to the type of the item W to be handled and ranks the types. In the index calculation process, the control system 3 sets the type value Va of each type to be handled so that the type value Va of each type is greater than the sum of the type values Va of all types that are ranked lower than the type in question.
- the control system 3 sets the type value Va of the type to be handled as the target type (the type being focused on), so that the type value Va of the target type is greater than the sum of the type values Va of all types lower than the target type.
- the ranking is done in order of shipping frequency, which is the frequency specified by the order information In.
- the ranking is done in order of the greatest need, so the more frequently needed a type is, the higher it will be, and the less needed a type is, the lower it will be.
- the control system 3 calculates the sum of the type values Va for all types included in each piece of order information In as the similarity index Ex for each piece of order information In. Because the type values Va are decimal values, the sum of the type values Va is also a decimal value.
- control system 3 sets the similarity index Ex to a binary value in the exponent calculation process. That is, in this embodiment, the control system 3 executes a process of converting the sum of the type values Va, which are expressed in decimal, into a binary number. This simplifies the calculation process of the similarity index Ex, making it easier to reduce the calculation process load on the control system 3.
- the order information In specifies four items W of type A, two items W of type C, and one item W of type D.
- the types of items W included in the order information In are "A", "C", and "D”.
- the type value Va of type A is "32”
- the type value Va of type C is "8”
- the type value Va of type D is "4", so the sum of these type values Va is "44”.
- the control system 3 converts this sum into a binary number to obtain a six-digit similarity index Ex of "101100". As such, in this example, since N is set to 0 to 5, the value converted into a binary number is a six-digit value.
- control system 3 performs stable sorting in the batch generation process, arranging the binary similarity indexes Ex for multiple pieces of order information In to be processed within a unit period in ascending order of the number of digits, and then in descending order of value.
- unit period is arbitrarily determined depending on the operation, and is set to, for example, one hour. Alternatively, this "unit period" may be set to half a day or one day.
- FIG. 6 an example is shown in which the number of order information In to be processed within a unit period is seven.
- the control system 3 executes an exponential calculation process to calculate a binary similarity exponent Ex for each of the seven order information In.
- the similarity exponent Ex for each order information In which in this example is a six-digit binary similarity exponent Ex, is compared in order starting from the first digit, with the larger value being moved to the top, and this is continued up to the final sixth digit.
- the similarity index Ex for the second order information In (order information In indicated by circle 2 in the figure) has the largest value and is shifted to the top digit.
- the similarity index Ex associated with the fifth order information In will ultimately be the highest, and the similarity index Ex associated with the third order information In (order information In indicated by a circle 3 in the diagram) will be the lowest.
- the control system 3 aggregates multiple pieces of order information In (in this example, the first to seventh pieces of order information In) to be processed within a unit period in order of similarity index Ex.
- the multiple pieces of order information In are aggregated in ascending (or descending) order of similarity index Ex in sets of a set number of aggregations (two pieces in the example shown in FIG. 7).
- the control system 3 aggregates multiple pieces of order information In that are close in order, obtained by stable sorting.
- the picking work related to each of the aggregated multiple pieces of order information In is treated as one batch work by the batch generation process.
