Description

Goods shelf

Technical Field

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

Background

A goods shelves for supermarket or convenience store, in order to save space, generally put back to back, the front end opening of each field on the goods shelves is outwards, and the staff can only put and take away the goods from goods shelves the place ahead. Generally, consumers are used to take goods at the front end of the column, if the worker places the goods at the front end of the column every time of replenishment, the goods at the rear end of the column are likely to be unsold for a long time, and the goods with short shelf life, such as food, are likely to be placed off the shelf due to overdue failure, so that economic loss and waste of the operator are caused. Because goods can only get in and out of the goods shelf from the front end of the column, if the width of the column is small, when workers put the goods at every time, the remaining goods in the column need to be taken out from the goods shelf one by one, then new goods are put at the rear end of the column, and the goods taken out before are put at the front end of the column, so that the operation is inconvenient, and the goods replenishment efficiency is low.

Disclosure of Invention

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

In order to solve the technical problem, the applicant proposes that the tray of the goods shelf is designed into a drawer type structure, the tray is firstly pulled out of the goods shelf when goods are replenished, and then the tray is returned into the goods shelf after goods are placed. Although the replenishment of workers is convenient, new technical problems are generated.

In consideration of the light weight design, the tray is generally made of thin metal or hard plastic, and after the tray is pulled out from the shelf, the tray is liable to shake up and down or back and forth due to the heavy weight of the tray on which the goods are placed and the large size of the tray. In addition, the tray of the drawer type structure is generally installed on the shelf by a sliding type connector (not a fastener), and the stability is poor, and even if the tray is located in the shelf, the tray is easily shaken back and forth when goods are placed on the tray. In a general convenience store, the sliding type connecting piece is easily damaged due to the shaking of the shelf, thereby affecting the service life of the tray. In unmanned convenience store, be provided with weight sensor in the tray of goods shelves for the change of response each column department goods quantity, no matter the tray is in goods shelves or outside the goods shelves, at the in-process of putting the column department with commodity, if the tray takes place to rock, must seriously influence weight sensor's measurement accuracy.

A second object of the present invention is to provide a shelf that can solve the problem that a drawer-type tray structure is likely to shake and has poor stability in a shelf of a convenience store.

In the intelligent goods shelf of the unmanned convenience store, a plurality of weight sensors are arranged in each tray and connected to data processing equipment such as a computer through a lead, 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. Generally, these wires are fixed to the shelf or the tray, but if the shelf is designed to be a drawer type structure, the fixed wires will limit the sliding of the tray. Therefore, the wire cannot be fixed to the shelf and must be movable. Therefore, new technical problems can be caused, and in the process of drawing the tray, a plurality of movable wires are easy to form a wound wire coil to occupy the space of the tray in the goods shelf, so that the tray cannot be pushed into the goods shelf; alternatively, the movable wires tend to snap into the sliding structure, causing the tray to become jammed and not slide smoothly into the shelf.

As shown in fig. 15, the present embodiment further includes a data processing device 5, which may be disposed outside the shelf or disposed inside the shelf, and is preferably mounted to the shelf support or the shelf back plate, where the data processing device 5 is preferably a computer or a server. The aforementioned weight sensor 33 is electrically connected to the data processing device 5 by a wire. In the normal use process of the shelf of the embodiment, the data processing device 5 can acquire the weight change of each storage box of each tray in real time, and when commodities are placed on the shelf or when the commodities are taken away from the shelf, on the premise that the single-item weight of the same type of goods placed on each storage box is known, the data processing device 5 can acquire the number of the commodities taken away or placed in each storage box through calculation.

As shown in fig. 9 and 11 to 14, when the worker needs to replenish the goods to a certain tray on the shelf, the locking device 4 is unlocked, specifically, fingers of both hands are inserted into the box body notches 411 on both sides of the bottom of the tray, the pull ring 4742 is pulled backward so that the locking piece 42 is disengaged from the locking bayonet 251a on the rear end of the locking plate 25, pulled into the locking box 41, thereby unlocking, and then the tray 4 is pulled out from the shelf. When the dampening slider 32 is pulled to the maximum length, at this time, the locking member 42 is disposed just opposite to the locking notch 251b at the front end of the locking plate 25, and at this time, the worker can take out his finger, and under the action of the elastic member 45, the locking member 42 is pressed downward to extend into the locking notch 251b, and locking is achieved again.

When the tray 3 is locked again, the user can place the remaining commodities in each storage box at the front end of the storage box and newly replenished commodities 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 acquisition accuracy of the weight sensor 33 is high. After all the commodities in the storage boxes on one tray are replenished, the worker unlocks the locking device 4 again, fingers are inserted into the box body gaps 411 on the two sides of the bottom of the tray, and pulls the pull ring 4742 backwards, so that the locking piece 42 is separated from the locking bayonet 251b at the front end of the locking plate 25 and pulled into the locking box 41, unlocking is completed, and then the tray 4 is pushed back to the shelf. When the length of damping slider 32 becomes minimum, locking piece 42 is just opposite to locking bayonet 251a at the rear end of locking plate 25, and at this moment, the worker can take out the finger, and under the action of elastic piece 45, locking piece 42 is pressed down and extends into locking bayonet 251a to realize locking again, so that in the subsequent commodity sales process, the stability of tray 3 is good, and the data acquisition accuracy of weight sensor 33 is high.
