ABSTRACT:
The present invention relates to a process for handling articles, particularly soft-good articles or hard-good articles, in the mail order business.
In the mail order business, a problem is posed by the fact that ordered items can always be returned by the customer. These articles, which are referred to as returns, must be made available for remailing, as they are generally articles that can be sent out again, i.e., they are not yet damaged or the like. However, this results in a series of problems, particularly due to the considerable quantities of returns, which can amount to tens of thousands of articles per day. Remailing is generally performed by restocking the returns to their original storage shelves, which can be done only manually and is very time-consuming. In view of the large number of articles this is hardly a practical system. It is also known to create a separate returns warehouse. Where the returns, which are recorded according to their type, are deposited and commissioned when they are needed. A process of this type is known from German patent document DE 43 32 315 C2. Within the framework of this process several returns are sorted into a storage container and transported to a returns warehouse, where they are picked manually as required. While this process has proven useful in practice, it is nevertheless relatively slow with respect to its duration from the time a return is received to the time it can be remailed, because a large number of handling steps must be performed.
However, for an economic and efficient commissioning and mailing of the considerable number of articles, a process that is both simple and permits a high throughput is also needed for the initial mailing of new articles.
The present invention is based at least on the objective of presenting a process of the above type that permits a swift handling of the articles, particularly remailing of received returns, and is, also a simple process.
To meet this objective, a process of the above type is designed such that, in accordance with the invention, each article is chaotically entered into a receptacle that holds only one article and is part of a commissioning device that comprises a plurality of receptacles. During this process the identifier of the receptacle and the identifier of the article are married to one another by a computer unit.
The process according to the invention advantageously places each individual article, be it a new article or a return, into a separate receptacle of a commissioning device, in such a way that the distribution across all receptacles is chaotic, i.e., any random article may be placed into any random empty receptacle. The advantageous marrying of the receptacle identifier to the article identifier permits a complete transparency of the stocking condition of the commissioning device, i.e., it is known at all times where which article is located. If a matching order is received, the respective article can easily be removed and removal is made very simple by the fact that each receptacle does not hold more than one article. Commissioning or recommissioning can, theoretically, take place as soon as the marriage of the identifiers has occurred. The inventive process is thus significantly faster than the known processes with respect to a possible mailing, particularly of returns. When commissioning is required, the article can be automatically dispensed from the receptacle, i.e., suitable automatically operated dispensing devices, such as flaps, are provided on the receptacle, which open when the article is needed so that the article can drop from the receptacle. In addition to or in lieu of this system, it is also possible to remove articles manually for commissioning purposes, in which case the given receptacle in which the required article is located is indicated by means of suitable visual indicators, e.g., in the form of a light-emitting diode.
To ensure that an order for a certain article is filled primarily by commissioning an article that may be present, so that the returns storage is emptied first, the inventive process may be such that when a commissioning order for an article is received, a check is first performed to determine whether the article is available in a commissioning device containing the returns, and if the return is present, this article is commissioned. Only if the requested article does not exist as a return is commissioning performed from the main or distribution warehouse, depending on how the overall warehouse is structured. In principle, however, the return is to be commissioned first. The returns are given priority in order to guarantee the swiftest possible cyclical emptying of the commissioning device.
According to the invention, the articles or returns may be entered into the receptacles manually and/or automatically. If stocking is done manually, the articles are simply placed, inserted or thrown into the receptacles, depending on how the commissioning device is structured and on the type of articles. To record the relevant identifiers, the process may be such that, if stocking is done manually, the identifiers of the respective receptacle and article are read-in or entered by means of an electronic reading or entry device, particularly a scanner, and/or entered by means of an input device, particularly a keyboard. This poses no problem, particularly if a bar code scanner is used, as the person processing the returns merely needs to scan the respective label on the receptacle and the label on the article once with the scanner, after which the data are already married to one another by the computer unit. It is advantageous if a radio scanner is used for this purpose, which may optionally have a keyboard to additionally permit manual entries. In lieu of the described “manual reading-in” of the receptacle identifier by means of the reading or entry device, the process may alternatively provide for an automatic entry of the receptacle identifier at the time the receptacle is stocked, e.g., by means of light barriers or the like that are actuated when the article is entered into the receptacle. In this case this leaves only the article identifier to be recorded. If stocking of the receptacles is performed automatically, according to the invention only the identifier of the article needs to be read-in with the aid of an electronic reading or entry device, particularly a scanner, and the receptacle identifier is entered automatically at the time the receptacle is stocked. The identifier may be a bar code. Alternatively—or in combination—a transponder may be used as the respective identifier or as means for transmitting the respective identifier, in such a way that the identifier is encoded and readable in the form of a magnetic field. The transponder may be attached on both, the article or its packaging material and the receptacle.
In an advantageous improvement of the invention, the empty receptacles that are available for stocking may be indicated by means of a visual indicator, which is advantageous particularly for the manual stocking process, since the operator immediately knows which receptacle is still available for stocking. However, also if stocking is performed automatically the indication of empty receptacles is advantageous, as it provides an indication whether there are any receptacle capacities left.
According to the invention, the operation of the commissioning device may furthermore be specifically designed so that it can be manipulated in such a way that one or more stocked articles are dispensed automatically in dependence upon one or more commissioning parameters, or that a visual indication is given of the articles to be picked. According to this embodiment of the invention it is, therefore, possible to specifically manipulate the commissioning operation, and thus the handling of articles, with computer entries of the specific commissioning parameter(s). This is required, for example, to be able to pick articles of which multiples exist in the commissioning device, or which have already been in the device for a certai
