Description

Goods shelf

Technical Field

The invention relates to a goods placing device for retail industry, in particular to a goods shelf.

Background

In order to save space, shelves for supermarkets or convenience stores are generally placed back to back, the front end opening of each column on the shelf faces outwards, and workers can only place and take goods from the front of the shelf. In general, consumers are used to taking the goods at the front end of the column, if the staff is put at the front end of the column every time of replenishment, the goods at the rear end of the column are likely to be unable to be sold for a long time, and the goods with a shorter shelf life such as food are likely to be put off the shelf due to expiration failing to be sold, so that economic loss and waste are caused for operators, therefore, the staff needs to put new goods at the rear end of the column and put the rest of the goods in the column at the front end of the column every time of replenishment. Because goods can only get in and out the goods shelves from the front end of the column, if the width of the column is smaller, workers need to take out the rest goods in the column from the goods shelves one by one when putting each time, then put new goods to the rear end of the column, put the goods taken out before to the front end of the column, and the operation is inconvenient and the goods supplementing efficiency is very low.

Disclosure of Invention

The first object of the present invention is to provide a shelf, which can solve the technical problems of the prior art that the convenience store can only replenish goods from the rear end of the tray, and the operation is troublesome.

In order to solve the technical problem, the applicant proposes a technical scheme that a tray of a goods shelf is designed into a drawer type structure, the tray is pulled out of the goods shelf when goods are replenished each time, and the tray is returned into the goods shelf after goods are placed. Although the staff is more convenient to replenish, new technical problems can be caused.

For light weight design, the tray is generally made of relatively thin metal or hard plastic, and after the tray is pulled out from the shelf, the tray is easy to shake up and down or shake back and forth due to the heavy tray with goods placed and the large size of the tray. In addition, such drawer-type trays are typically mounted to the shelves by means of sliding connectors (not fasteners) that provide poor stability and are subject to back and forth rocking when the product is placed in the tray, even if the tray is located within the shelf. In a common convenience store, rocking of the shelves can cause the sliding connectors to be easily damaged, thereby affecting the service life of the tray. In unmanned convenience stores, be provided with weight sensor in the tray of goods shelves for the change of the goods quantity of each column of response, no matter the tray is in the goods shelves or outside the goods shelves, in the in-process of putting the goods to the column, if the tray takes place to rock, can necessarily seriously influence weight sensor's measurement accuracy.

The second object of the present invention is to provide a shelf, which can solve the technical problems of easy shaking and poor stability of drawer type tray structure in the shelf of convenience store.

In the intelligent goods shelf of the unmanned convenience store, a plurality of weight sensors are arranged in each tray and are connected to data processing equipment such as a computer through wires, and the data processing equipment monitors the quantity change of goods on each column in real time according to the real-time data change of each weight sensor. Typically, these wires are fixed to the shelves or trays, but if the shelves are designed as drawers, the fixed wires limit the sliding movement of the trays. Thus, the wire cannot be fixed to the shelf and must be movable. Therefore, some new technical problems can be generated, a plurality of movable wires can easily form winding wire coils in the process of drawing the tray, and the tray space in the goods shelf is occupied, so that the tray can not be pushed into the goods shelf; or the movable lead is easy to be clamped into the sliding structure, so that the tray is clamped and cannot slide into the goods shelf smoothly.

When the tray 3 is locked again, the user can place the remaining goods of each storage box at the front end of the storage box and place the newly-supplemented goods at the rear end of the storage box. In this process, since the tray is still in the locked state after being pulled out, the stability of the tray 3 is good, and the data collection accuracy of the weight sensor 33 is high. After the goods of all the storage boxes on one tray are supplemented, the staff unlock the locking device 4 again, insert fingers into the box body notches 411 on two sides of the bottom of the tray, pull the pull ring 4742 backwards, enable the locking piece 42 to be separated from the locking bayonet 251b at the front end of the locking plate 25, and be pulled into the locking box 41, so that unlocking is completed, and then push the tray 4 back into the goods shelf. When the length of the damping slider 32 becomes minimum, the locking member 42 is just opposite to the locking bayonet 251a at the rear end of the locking plate 25, at this time, a worker can take out his or her finger, and under the action of the elastic member 45, the locking member 42 is pressed down and extends into the locking bayonet 251a, so as to lock again, thereby ensuring good stability of the tray 3 and higher data acquisition accuracy of the weight sensor 33 in the subsequent commodity sales process.
