The present embodiment provides a shelf, which includes a plurality of parallel brackets (not shown), a plurality of trays 100 are detachably mounted on any two adjacent brackets, and the trays 100 can be horizontally arranged or arranged parallel to each other on the shelf. In other embodiments, the shelf or tray 100 may be mounted in a refrigerator or freezer.

As shown in fig. 1 to 3, the present embodiment provides a tray 100, which includes a supporting plate 1, a guide rail 2, a first baffle 3, a push plate 4, and a distance sensor 5.

The pallet 1 is used for placing goods; the guide rail 2 is arranged on the top of the supporting plate 1 and extends from the front end of the supporting plate 1 to the rear end of the supporting plate 1; the first baffle 3 is vertically connected to the front end of the guide rail 2; the push plate 4 can be slidably mounted on the guide rail 2, and one side surface of the push plate 4 is opposite to the first baffle 3; the distance sensor 5 is arranged at the rear end or the front end of the supporting plate 1, and the other side surface of the push plate 4 is opposite to the distance sensor 5; the distance sensor 5 is used for acquiring the distance between the push plate 4 and the distance sensor 5 in real time. Wherein, goods are placed on the guide rail 2 between the push plate 4 and the first baffle 3, the embodiment preferably places the same kind of goods on the same guide rail, the same kind of goods have the same size and the same weight of standard goods, and the size deviation and the weight deviation of the same kind of goods are less than or equal to 10%.

Further, in another embodiment, the tray 100 may further include a weight sensor 13, an upper surface of one end of the weight sensor 13 is connected to the lower surface of the pallet 1, and a lower surface of the other end thereof is connected to the upper surface of the bottom plate 11. The weight sensor 13 is used for acquiring a weight sensing value of each tray 100, that is, a total weight of at least one article placed on the pallet 1, and the data processing unit 200 may detect a pick-and-place state of the article in the tray 100 in real time according to a comparison change of the weight sensing value of each tray 100.

When an article is taken away from or put back on a tray 100, the data processing unit 200 determines the taking and placing states of the articles in the plurality of trays 100 on the shelf according to the comparison change of the total weight of the article, and if the weight value corresponding to a certain tray 100 becomes smaller, it can be determined that the article on the tray 100 is taken away; if the weight value of a certain tray 100 becomes large, it can be determined that the goods are put back on the tray 100.

In this embodiment, it is preferable that the same type of goods are placed in the same column, and have the same weight value, and the weight value of each type of goods pre-stored in the goods database is combined, and further, the type and the number of the goods taken away or put back can be calculated according to the variation of the weight sensing value corresponding to each tray 100. Since the weight value of each tray 100 is collected in real time, not the weight value of each column, the determination result is not necessarily unique, and there may be multiple possible calculation results at the same time.

When some users take or put goods back to the tray 100 from the tray 100, the push plate 4 may be pushed backwards for a certain distance before the goods are taken or put, and the goods may stay for a short time, and the push plate 4 is opened after the goods taking and putting operation is completed; some users may intentionally push or pull the goods on the tray 100 to push the push plate 4 a certain distance backward, but do not complete the operation of removing or returning the goods from or to the tray 100, but leave the push plate 4 after a long time; after the push plate 4 is released, the push plate slides forwards rapidly under the action of the elastic piece to clamp the goods again. In this process, the distance between the push plate 4 and the distance sensor 5 may change several times in a short time, and if only the scheme related to the distance sensor 5 is adopted, more determination errors may occur in the pick-and-place state determining unit 230; therefore, if the scheme related to the distance sensor 5 is combined with the scheme related to the weight sensor 13, two methods can be adopted to simultaneously perform the pick-and-place state determination on the same column of the same tray 100 twice.

In the present embodiment, the scheme of providing the distance sensor 5 above the tray 100 is used to determine the kind and number of the removed or replaced goods, and the scheme of providing the weight sensor 13 in the tray 100 is used only to verify the determination result of the previous scheme. When the data processing unit 200 makes a judgment result based on the real-time data of the distance sensor 5, if the judgment result is identical to one of the calculation results made based on the real-time data of the weight sensor 13 in the same period, or the weight value of the goods corresponding to the judgment result is identical to the variation value of the weight induction value of the pallet 100 in the same period, the result can be considered to be accurate; if not, the data processing unit 200 will alarm to remind the staff of manual intervention. The two results are consistent here, meaning that the error of the two result data is less than 5%. In the embodiment, the numerical value number based on the weight sensor 13 is adopted to make the calculation result, so that the accuracy of judgment is increased, and the error rate can be effectively reduced.

Because layer board 1 is longer and yielding, in order to prevent that layer board 1 from being buckled by goods, as shown in fig. 3, set up strengthening rib 31 between layer board 1 and bottom plate 11 for support layer board 1, ensure that layer board 1 bottom surface and top surface keep the level and can not rock, prevent that the guide rail from warping and leading to the slip obstacle of push pedal, can also guarantee the accuracy that weight sensor 13 weighed. In this embodiment, the tray 100 further includes a label holder 15 and a bar light source 16, the label holder 15 is connected to the front end of the supporting plate 1; a bar light source 16 is provided in the label holder 15 for illuminating the label holder 15 or providing illumination for the tray 100. The label support 15 can be attached with labels or can be provided with slots for clamping labels, and the commodity information of different commodities 6 is written, so that a user can know the commodity information conveniently, such as the name, type, production place, price and the like of the commodities. Tray and goods shelves, in intelligent retail industry, especially unmanned supermarket field of selling goods have very important application.

The above are only preferred embodiments of the present invention, which will make it clear for a person skilled in the art how to practice the invention, and these embodiments do not limit the scope of the invention. For those skilled in the art, without departing from the principle of the present invention, several improvements and decorations can be made, and these improvements and decorations should also be regarded as the protection scope of the present invention.
