Description

Electronic goods shelf

Technical Field

The invention relates to a material storage rack, in particular to an electronic goods shelf.

Background

Application number is 201920313444.9's chinese patent discloses an electronic goods shelves, braced frame including the left and right sides, be equipped with the tray frame that a plurality of upper and lower intervals set up between the braced frame of both sides, the tray frame is made by the sheet metal component punching press, the tray frame has a plurality of standing grooves, a standing groove is used for placing of a charging tray, it separates to control adjacent standing groove through the metal strip of tray frame, still be equipped with identification label and LED lamp on the tray frame, every standing groove corresponds an identification label and an LED lamp, be equipped with reference numeral and bar code or two-dimensional code on the identification label. The material tray is of a round box-shaped structure, some material trays are transparent and some material trays are opaque, the surface of each material tray is also provided with an identification label, and the identification labels on the material trays are used for informing the system of the type and the quantity of materials in the material trays. The identification label that the standing groove corresponds is used for the quantity and the model of the material of placing in this position of record, and the kind, the model or even quantity of the material that will place all is inequality in the adjacent standing groove.

When workers need to place the material trays filled with specified quantities of specified types of materials on the electronic goods shelf, the workers firstly scan the identification labels on the surfaces of the material trays and then can adopt a recommended storage position mode or a random storage position mode to control the materials. When the storage position mode is recommended, the control system of the electronic shelf sends out an instruction to inform a worker to place the tray in the specified placing groove. And in the random storage mode, workers judge to place the material discs on the placing grooves without the material discs according to manual work.

Because the standing groove quantity on the charging tray frame is more, the workman is easy with the charging tray misplacing, and control system can record the model and the quantity of the material of storing by mistake. There is a need for an electronic shelf that can be used to detect the presence of a tray in a holding groove.

Disclosure of Invention

The invention aims to provide an electronic shelf which can be used for detecting whether a tray exists in a placing groove or not.

In order to achieve the purpose, the invention adopts the following technical scheme: an electronic goods shelf comprises a goods shelf frame, wherein the goods shelf frame is provided with a plurality of placing grooves which are arranged at intervals left and right, a plurality of positioning assemblies are arranged on the goods shelf frame and correspond to the placing grooves one to one, each positioning assembly comprises a fixed block fixed on the goods shelf frame, each fixed block is provided with a containing groove, a photoelectric sensor is arranged in each containing groove and comprises a light emitting part and a light receiving part, each fixed block is provided with a forward or upward or backward opening stepping groove, each stepping groove is communicated with each containing groove, one end of each movable block is positioned in each stepping groove and fixed with a stop block, each stop block extends into each containing groove and is positioned between the light emitting part and the light receiving part, and the other end of each movable block extends to the outer side of each; when the tray is placed in the placing groove, the tray pushes the movable block to move, so that the stop block moves out of or between the light emitting part and the light receiving part.

Each placing groove corresponds to a confirming component, when the material tray is placed in the placing groove, the material tray is contacted with the movable block and presses the movable block downwards or backwards or forwards, so that the movable block drives the stop block to move, the stop block is moved out of or between the light emitting part and the light receiving part, and finally the photoelectric sensor sends a signal to confirm which placing groove the material tray is placed in. The setting can be carried out, if the appointed standing groove that the charging tray will be placed is inconsistent with the standing groove that photoelectric sensor corresponds, then explain the workman has placed the charging tray in wrong standing groove, and control system can issue the instruction again in order to remind the workman to misplace the charging tray. The invention has the advantages that the invention can be used for detecting whether the material tray is arranged in the placing groove, so that the electronic shelf control system can detect whether the placing position of the material tray is correct and can ensure that the information recorded by the control system is correct.

The setting of holding tank is in order to avoid the external world to disturb photoelectric sensor to improve and detect the precision.
