Definitions

  • the invention relates to a device according to claim 1, a system according to claim 10, an arrangement according to claim 13 and a method according to claim 16.
  • Storage racks are usually dirty after they have been installed and/or put into operation and/or after a certain period of use in a rack warehouse.
  • the dirt can come from the environment and can be, for example, dust that is created during the construction of the rack warehouse or that is brought into the rack warehouse from outside. But abrasion, for example from the rubber wheels of a storage and retrieval machine, can also settle on the storage rack.
  • Dirt on the storage rack and in particular on the crossbeams used to store goods can have negative effects. This includes, for example, that the dirt can settle on the goods stored in the storage rack and contaminate them. It is also possible that the dirt covers sensors, which impairs their function and can subsequently lead to operational disruptions.
  • dirt can affect the power supply of a storage and retrieval machine, especially a single-level storage and retrieval machine, if it gets onto a power bus used for it.
  • dirt from the storage rack or the crossbeam can get onto a rail of the storage and retrieval machine, which can cause the wheels used to move the storage and retrieval machine to slip.
  • the object of the present invention is to provide a device, a system and an arrangement with such a device as well as a method which enables a fully automated cleaning of a storage rack and in particular its crossbeams.
  • a device for the fully automated cleaning of a storage rack, in particular its crossbeam used for storing stored goods, wherein the device has external dimensions which are at least similar and preferably identical to those of a loading aid stored in the storage rack, so that the device can be handled by means of a load-handling device of a storage and retrieval machine, preferably a single-level storage and retrieval machine.
  • the external dimensions of the device also referred to as a cleaning unit or cleaning module, that are relevant for handling with the load-handling device of the storage and retrieval machine are those that are located at the interfaces, also referred to as handling points, between the load-handling device and the device.
  • the device can preferably be grasped with fingers provided on the load-handling device of the storage and retrieval machine, so that it can be moved, in particular pushed, away from and towards the storage and retrieval machine.

  • the goods to be stored in the storage rack or already stored there can be arranged in such a loading aid to make it easier to handle, for example using the storage and retrieval machine.
  • the goods can be a crate, a box, a bag and/or an individual article that is stored in the storage rack without a loading aid.
  • the storage rack preferably has cross beams, also referred to as cross braces or cross traverses, as well as longitudinal beams, also referred to as longitudinal braces or longitudinal traverses. Both the cross beams and the longitudinal beams run horizontally in the storage rack.
  • the storage rack also has vertical support pillars, which are anchored in particular in the floor of a rack storage facility. The cross beams and longitudinal beams are attached to the support pillars and extend perpendicular to them.
  • the storage rack preferably has several rack levels, each of which is formed by several cross beams and several longitudinal beams.
  • One or more cross beams and, if necessary, one or two longitudinal beams form a storage space for the stored goods.
  • the device can be handled not only by the storage and retrieval machine but also by other goods transport means of the storage rack, for example by means of a rack conveyor, by means of a lift, by means of a lift conveyor or by means of a so-called cross conveyor location in the storage rack, and can preferably be transported to any storage location in the storage rack.
  • the device according to the invention also makes it possible to clean the longitudinal beams.
  • the device when the device is moved, in particular pushed, towards one of the cross beams, at least a portion of a longitudinal beam arranged between the storage and retrieval machine and the cross beam is first cleaned.
  • a longitudinal beam arranged behind the cross beam as seen from the storage and retrieval machine or a portion thereof can also be cleaned, provided that the load-carrying device of the storage and retrieval machine can reach it with the device.
  • the device is designed in such a way that it can be used to clean, in particular, a surface of the crossbeams and/or longitudinal beams facing the stored goods.
  • the storage rack can also have, in addition to the vertically running support pillars, large-area shelves for forming the shelf levels or storage spaces, in which case the shelves in particular can be cleaned with the device according to the invention.
  • the cleaning of the storage rack can be carried out fully automatically. Maintenance personnel do not need to enter the storage racks, so no safety precautions are necessary.
  • the device according to the invention also allows for a partially automated cleaning process. Cleaning of the storage rack is possible, whereby the device can be moved manually to different areas of the storage rack, for example.
