Description

Comprehensive cleaning device for elevated warehouse tray

Technical Field

The invention belongs to the technical field of cleaning devices, and particularly relates to a comprehensive cleaning device for trays of an elevated warehouse.

Background

The pallet is a carrier for converting static goods into dynamic goods, and is a carrier which is used in loading, unloading, transporting, warehousing and transportation processes. At present, raw materials, auxiliary materials and finished products of enterprises in the cigarette industry are loaded, unloaded, transported and stored through trays, and the storage, the warehouse entry and the warehouse exit processes of various raw materials, auxiliary materials and finished products in an elevated warehouse are completed through the trays. At present, most of trays in an elevated warehouse of cigarette industry enterprises are wooden 'Chuan' -shaped flat trays, most of the surfaces of a top plank and a bottom plank of the upper portion of each tray can scatter and accumulate dust and sundries after the 'Chuan' -shaped wooden flat trays are used in the elevated warehouse for a period of time, especially, raw material tobacco powder can be accumulated on the trays of the raw material elevated warehouse, if the trays are not cleaned for a long time, the tobacco powder can be left on the trays, favorable conditions are created for breeding and reproduction of tobacco insects, and the elevated warehouse, especially the raw material insect pests, can be caused to occur in a large area, so that the cigarette quality is seriously influenced.

At present, the main cleaning method of the logistics department of the cigarette industry enterprise comprises the following steps: and (4) regularly drawing the hollow tray group of the elevated warehouse out of the room, then manually cleaning the trays, and putting the trays into the elevated warehouse after cleaning. This manual sweeping presents two problems: firstly, the cleaning mode has larger cleaning randomness, and most trays cannot be cleaned due to the occupation of materials, so that the cleaning quality cannot be ensured; secondly, the logistics department needs to consume a large amount of manpower and material resources for cleaning the tray.

In order to save manpower and material resources, the invention of the logistics tray cleaning system (CN208213877), the invention of the tray cleaning device (CN210449965) and the invention of the tobacco material logistics elevated warehouse storage system (CN110949928) are designed with the tray cleaning device, and the automatic cleaning of the trays is realized. But above-mentioned this tray cleaning device also can only clean the upper portion top bed plate of tray, and the bed plate still can not clean at the bottom of the lower part, and the bed plate does not clean for a long time at the bottom of the lower part also probably leads to debris such as tobacco powder to leave over on the tray, for tobacco worm breed, multiply and create the advantage, still lead to the raw materials insect pest to take place in a large scale finally, seriously influence cigarette quality. There is therefore a need for improvements.
