Definitions

  • the invention relates to a storage system for storing and picking articles, in particular pharmacy articles.
  • the warehouse is a drawer storage whose drawers can be extended and retracted by means of telescopic poles.
  • the computer assigns the article the optimal storage location.
  • the article is removed from the conveyor belt and stored in its predetermined storage location. If the article is now requested by the pharmacist, the article is placed by means of the robot from the storage location and onto a conveyor belt.
  • the computer receives a signal that the storage location is free again.
  • the arrival of the article in the sales room of the pharmacy is determined.
  • the procedure described in DE 43 18 341 B4 is prone to failure in practice. Failure to store the article at the storage location or when removing the article will cause the number and identity of the actual articles may differ from the data stored in the computer.
  • the device provides no way to determine which items are actually at the storage locations. This requires a human inspection of the storage locations, which, due to the construction of the warehouse and the intended method of sizing the articles, necessitates interruption of the picking and subsequent inspection by a pharmacy employee.
  • DE 10 2008 027 646 A1 discloses an automated storage system for small parts, in which the small parts are detected by cameras before storage and the images are evaluated by means of an electronic data processing system.
  • the storage system has a plurality of trays, which can be individually requested and transferred to a serving for picking or removal of articles placement space by means of a paternoster-like system.
  • a table-like storage area is provided at the place of placement, to which items are placed prior to storage in the requested tray.
  • the cameras for detecting the articles are arranged in the ceiling area of the storage system above the placement space or on the side walls of the storage system, these cameras being directed to the storage area.
  • DE 10 2006 047 956 discloses a device for monitoring the filling level of piece goods in machine shafts of a picking system.
  • the device comprises a camera which is directed onto a machine shaft.
  • To determine the number of articles in the machine slot an image of the machine slot is taken and image data is transmitted to an evaluation unit.
  • image data is transmitted to an evaluation unit.
  • Reference marks are provided in the machine wells, which are covered or exposed depending on the level of the articles. On the basis of these reference marks statements about the level can be made by means of image processing programs.
  • a reference system is required, either reference data or reference marks, which requires additional effort and increases the susceptibility to errors.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • a storage system for storing and picking articles, in particular of pharmacy articles should be specified so that a permanent and reliable overview of the number of articles that is located in a storage unit, for example a hopper, is made possible. Furthermore, a method is to be specified that allows a more accurate monitoring of the inventory of articles in the storage system.
  • a storage system for storing and order picking of articles, in particular of pharmacy articles, which comprises a plurality of side by side, substantially vertically extending filling ducts, each hopper having a filling opening extending substantially over the entire height of the hopper extends and over which the articles to be picked can be introduced into the hopper.
  • the storage system further comprises at least one camera, which is directed to the filling opening of at least one hopper and continuously receives images of the filling opening and, if present, the articles, which are located in the hopper.
  • the storage system comprises an electronic data processing system which is connected to the at least one camera, wherein software is stored in the data processing system which extracts information about the number of articles in the feed chute from the images transmitted by the at least one camera ,
  • one or more cameras are provided, which are directed to the filling openings of the filling ducts. These cameras continuously generate images from the fill openings. These images are evaluated by means of software stored on the data processing system. Using mathematical algorithms The information stored in the software determines information about the number of articles in each of the filling ducts.
  • information about the number of articles in each hopper means the number of products in one fill level, but it is not necessary to determine the number of articles, for example, it may be sufficient to set the fill level in the hopper From the dimensions of the articles, which are likewise deposited in the data processing plant, then the number of the articles can be computed.
  • no reference systems like older reference data sets or reference markings are necessary Calculating items in one or more feed trays from each image without resorting to older images or markers, thus avoiding a comparison between current data and reference data to obtain information about the number of items in each of the feed trays this way w Higher safety of the results is achieved because they are independent of a reference system.
  • the information about the number of articles in each of the filling ducts is preferably obtained by means of metrological triangulation methods with the aid of the camera (s) and software adapted therefor.
  • the storage system according to the invention allows a constant monitoring of the filling level of the articles in the filling ducts.
  • the monitoring is therefore not limited to the time of storage or issue of an article. Therefore, the actual levels are always known, which significantly reduces the occurrence of errors in storage and picking.
  • Changes in filling levels de are detected immediately, ie in real time or almost in real time. In particular, all changes in the fill levels are detected, for example, those resulting from malfunction or manipulation of the storage system.
  • Another advantage of the storage system according to the invention is that the individual storage units, here the hopper, need not be moved to determine the number of articles therein.
  • Each hopper is preferably associated with a respective camera.
  • the number of cameras may be smaller than the number of filling shafts, for example if a camera takes pictures of several filling shafts.
