Description

Goods shelf

Technical Field

The invention relates to an article storage device for retail industry, in particular to an intelligent shelf.

Background

In the technology of an unmanned supermarket or an unmanned convenience store, the problems of judgment and record of goods selected by a customer need to be solved, specifically, the type of goods taken away from a shelf by the customer, the quantity and unit price of the goods taken away by the customer and the like need to be accurately judged by a computer system so as to settle accounts for the customer.

In the prior art, a weight sensor is generally installed below columns, and the types and the quantity of sold goods are judged by monitoring the weight change of the goods on different columns in real time. In such a solution, the two adjacent fields and the goods on the two fields cannot be contacted in any way, which would affect the data accuracy of the weight sensor.

In the prior art, the column size of the shelf is usually not adjustable, the width and the spacing of the columns cannot be adjusted by self, and the width of each column of the shelf is limited and cannot adapt to goods with different sizes.

However, the widths of different kinds of goods in convenience stores are often different, if the width of each column is constant, the kinds of goods that can be placed on each shelf are few, and convenience store operators need to prepare a large number of trays with different widths in order to place goods with different widths, and each tray is used for placing goods with a proper size, so that the storage cost, the management cost and the operation cost are high.

In the field of unmanned convenience stores, a shelf with adjustable column spacing is needed, so that the shelf can be used for placing goods with different widths and different types, and the storage cost and the management cost of the convenience stores are reduced.

Chinese patent CN108703590A discloses a shelf, which adopts a structure that the trays are designed to be spliced and combined, the weight sensor is detachably mounted on the shelf substrate through a clamp, and the tray is detachably mounted on the weight sensor through a clamp. In this scheme, each tray is a column, and a weight sensor is arranged in the middle of the lower part of each tray. The operator can take off tray, weight sensor from the goods shelves base plate, splices into a tray with a plurality of trays to make the tray can put the goods of different width, reduce operator administrative cost. Simultaneously, this scheme is through demolising, removing and installation weighing sensor for there is just only one weighing sensor in the middle part of tray below after the combination, lets the middle part of the tray after the width adjustment directly over weighing sensor, in order to guarantee the accuracy that the sensor gathered weight numerical value.

The disadvantages of this solution are:

first, when a plurality of tray subassemblies are connected each other and are made up into a big tray, only have a anchor clamps between tray and the weight sensor, only have an anchor clamps between weight sensor and the bottom plate, the tray four corners department takes place to rock easily, and stability is relatively poor, can influence weight sensor's data accuracy. When the weight sensor is installed, if the weight sensor is not arranged below the middle part of the large tray, the gravity center of the tray and the commodity is not right above the sensor, and the data accuracy of the sensor is also influenced.

Second, the operator's process of adjusting the width of the pallet is too cumbersome to adjust directly on the shelf. For example, if an operator wants to adjust the width of a tray to be larger, the operator needs to remove a plurality of trays from a shelf, remove side plates on the left and right sides of the tray, connect a plurality of tray assemblies into a whole in an assembling manner, remove a plurality of weight sensors, adjust the positions of the rest weight sensors, and install the assembled tray on the shelf so that each sensor is positioned in the middle below one tray. If the number and the positions of the weight sensors are not adjusted, the gravity center of the tray is inconsistent with the sensors, and the accuracy of the sensors is affected.

Third, the weight data that the weight sensor gathered in real time includes the weight of the goods on tray, anchor clamps and the tray, because the range of every sensor is limited, the tray weight after the combination is great, the weight of anchor clamps is also great, can occupy great partly in the sensor range, forces the operator to select the weight sensor of bigger range, cost height to promote shelf cost. For example, in the solution of the aforementioned reference, if only the weight sensor with the upper range limit of 3 kg is selected, but the total weight of the combined tray and the clamp reaches 1 kg, only the lighter goods can be placed on the tray. However, goods having a large width are likely to weigh a lot, and therefore, convenience store operators are forced to use weight sensors having an upper range limit of 10 kg.

Fourthly, each goods shelf all needs a large amount of anchor clamps of installation (two anchor clamps are installed to a weight sensor), has inevitably promoted the hardware cost of goods shelf, though can reduce the purchase and the administrative cost of tray to a certain extent, it is relatively poor to fall this effect, can not satisfy convenience store operator's demand.

In the embodiment, each sensor only needs to bear the weight of one small bracket and one small tray except the weight of goods on the tray, so that only a weight sensor with a small measuring range needs to be selected; if a plurality of small trays are combined into a column, the weight of the goods can be shared by a plurality of sensors under the same column, so that the cost of the weight sensor can be further reduced.

As shown in fig. 4 and 5, the deck board 100 further includes a reinforcement panel 101; the reinforcing plate 101 is fixed to the upper surface of the base plate 10; the bottom surfaces of the one ends of the plurality of weight sensors 30 are connected to the same reinforcing plate 101. An elongated buffer plate 103 can be further arranged between the reinforcing plate 101 and the base plate 10 to achieve a better fixing effect, so that the whole tray is more stable. The weight sensor 30 is provided at both ends thereof with vertical through holes, respectively, and at one end thereof, a bolt may be passed through the buffer plate 103 and the reinforcing plate 101 to connect the lower surface of one end of the weight sensor 30 to the base plate 10, and at the other end thereof, a bolt may be passed through the spacer 21 to connect the upper surface of the other end of the weight sensor 30 to the bracket 20.

As shown in fig. 4 and 5, in this embodiment, the deck boards 100 further include gusset baffles 102; the reinforcing plate baffle plate 102 is vertically connected to the rear end of the reinforcing plate 101 and is made into an integrated structure with the reinforcing plate 101 so as to further improve the rigidity of the reinforcing plate 101; gaps exist between the reinforcing plate baffle 102 and the bracket 20 and the tray 40 so as not to influence the measurement accuracy of the weight sensor. In order to achieve light weight of the deck board, the base plate 10 of the deck board 100 is generally a metal thin plate, when the width and length of the base plate 10 are large, the base plate 10 is likely to be partially shaken or warped, and the reinforcing plate 101 and the reinforcing plate baffle plate 102 can make the base plate 10 more firm and less prone to shaking or warping.

In this embodiment, each column 110 may be composed of one tray, or may be composed of a plurality of trays, and includes more than two tray bottom plates 41 and two tray side plates 42; a gap is formed between any two adjacent tray bottom plates 41, the width of the gap cannot be too large or too small, and is generally 5mm-30mm, preferably 10mm, 15mm or 20mm, so as to avoid the mutual interference of two adjacent trays 40; two tray side plates 42 are respectively installed to the left and right sides of the column 110. When the two sides of the gap have the tray side plates, the two tray bottom plates on the two sides of the gap respectively belong to two different columns, if the width of the gap is too small, commodities in the two columns can contact with each other and interfere with each other, and the data accuracy of the weight sensor is influenced. When no tray side plate exists on two sides of the gap, two tray bottom plates on two sides of the gap belong to the same column, the gap is located at the bottom of the column, and if the width of the gap is too large, more space is wasted, and the layout of the trays is affected.

When all the goods placed on one shelf are small-width goods, a column is formed by using one tray, for example, a tray with the width of 10cm can be used for placing goods with the width of 8 cm. When goods with larger width need to be placed on the goods shelf, an operator can directly disassemble two adjacent tray side plates 42 respectively belonging to the two trays 40, so that the two adjacent trays 40 form a column 110, and the width of the column is 2 times of the original width; further, the operator can detach the tray side plates 42, so that the adjacent trays 40 form a column 110, and the column width is changed to be multiple times. The disassembly and the installation of the tray side plate 42 are simple and convenient, and a user can directly operate on the goods shelf plate without disassembling the tray from the goods shelf, so that the popularization and the application are convenient. After the width of the column is adjusted, the number of the weight sensors corresponding to the column is also changed, if the number of the trays of the column is changed from one tray to a plurality of trays, the sum of a plurality of weight sensing values acquired by the weight sensors below the plurality of trays is the real-time weight sensing value of the column, and a worker needs to modify setting parameters in a computer system through a keyboard or a handheld terminal so as to ensure that the real-time weight sensing value of the column in the computer system is real and credible. For example, six trays with the numbers of a1, a2, A3, a4, a5 and a6 are arranged on one deck of the shelf, six weight sensors with the numbers of B1, B2, B3, B4, B5 and B6 are respectively arranged below the deck of the shelf, originally, each tray forms a column, and the computer can simultaneously acquire six real-time weight values which are respectively weight sensing values of each column. If three adjacent trays are combined into a column, the trays A1, A2 and A3 form a first column, the trays A4, A5 and A6 form a second column, setting parameters need to be changed in a computer system, real-time data collected by the sensors B1, B2 and B3 are summed, and the obtained total weight value is the weight sensing value of the first column; and summing the real-time data collected by the sensors B4, B5 and B6 to obtain a total weight value, namely the weight induction value of the second column.

Generally, larger size items and trays are heavier, and if only one weight sensor is located under a widened field, the range requirement for the sensor is high, e.g. 0-20 kg, which is generally expensive, and a convenience store requires a large number of weight sensors, which can be prohibitively expensive. In this embodiment, be equipped with a weighing sensor in each tray below, when a column was constituteed to a plurality of trays, the weight of a column was distributed on a plurality of weighing sensor, and tray and support occupy the range less, and convenience store operator can use the weighing sensor that the range is less, the price is lower, need not to adjust weighing sensor position, also need not to use anchor clamps, can effectively reduce hardware cost and promote measurement accuracy.

In the embodiment, the width of the column 110 is adjusted by plugging and pulling the tray side plate 42, so that the technical problems of single column width and high management cost of the existing shelf can be solved; on the other hand, in the embodiment, the size of the column 110 can be adjusted without detaching the lower tray 40 and the weight sensor 30, the operation is simple and convenient, and the structure of a clamp and the like which are convenient to detach is not needed, so that the shelf is light in weight, small in size and low in cost.

In this embodiment, the deck board 100 further comprises a data processing device (not shown) connected to the plurality of weight sensors 30. The weight sensor 30 is used for acquiring a real-time weight value of each column 110 in real time, wherein the real-time weight value is a sum of real-time values of at least one weight sensor 30 below each column 110, namely, a total weight of the tray, the bracket and goods on the tray at each moment. After the setting of the collection frequency and the time interval of the weight sensor 30 is completed, the difference between the two adjacent real-time weight values of each column 110 is the weight value of the goods which changes in the column, the weight value of the goods of each column is stored in advance, and the data processing device can calculate the number of the goods which are taken away or put back.

Example 2

As shown in fig. 8, the present embodiment 2 includes all the technical features of the embodiment 1, and is different from the embodiment 2 in that a proximity sensor 50 is further included, which is connected to a data processing device (e.g., a computer system), and the proximity sensor 50 is disposed on the upper surface of the substrate 10; each proximity sensor 50 is disposed opposite a third mounting hole 413 and/or a fourth mounting hole 414. The data processing equipment is used for acquiring the position of each side plate on the goods shelf plate in real time and acquiring the corresponding relation between each column and at least one weight sensor.

The left side and the right side below each tray are respectively provided with at least one proximity sensor 50, which can be positioned below the brackets 20 at the front end and the rear end, or below the middle part of the left side and the right side of the tray bottom plate. The tray side panels 42 on the left and right sides of the tray bottom panel are removed or installed and can be sensed by the proximity sensors 50. When the side plate fixture block 421 is arranged in the third mounting hole 413 or the fourth mounting hole 414, the proximity sensor 50 is arranged opposite to the side plate fixture block 421, so that the existence of the tray side plate 42 can be judged; when a certain tray side plate 42 is removed, the proximity sensor 50 cannot sense the side plate 42, so that the computer system can judge the position of the tray side plate 42 remaining on the shelf plate according to the sensing signal of each proximity sensor 50, thereby determining the position and the width of each column 110, and the computer system can find out the position and the number of the weight sensor corresponding to each column from the position and the width, and set the real-time weight value corresponding to each column to be the sum of at least one real-time value collected by at least one weight sensor below the column. That is to say, after the staff manually demolishs or installs the tray curb plate, computer system can acquire the position, the width of each field and the weight inductive value that corresponds in step, and then can monitor the commodity quantity change of this field according to the change of weight inductive value, need not to reset the position of field, weight inductive value with the manpower, has realized computer system's full automated control.

The proximity sensor 50 is preferably a hall sensor, and in this case, the side plate latch 421 is made of a magnetic material in whole or in part. For example, the surface of the side plate latch 421 is provided with a magnetic layer containing a magnetic material. When the side plate latch 421 is inserted into the third mounting hole 413 or the fourth mounting hole 414, the distance between the hall sensor 50 and the side plate latch 421 is less than the sensing distance (for example, 10 mm) of the hall sensor, and the computer can determine whether the side plate 42 exists at the position corresponding to the sensor.

At least two proximity sensors 50 are arranged below each tray 40, and are used for sensing whether the side plates 42 exist on the left side and the right side of the tray 40 or not, and can be positioned below the brackets 20 at the front end and the rear end or positioned below the middle part of the sensing tray 40.

In one embodiment, all proximity sensors 50 are arranged in a straight line, as shown in FIG. 9. All the proximity sensors 50 may be arranged in a corresponding one of the straight lines under the tray front plate 43 or the tray rear plate 44.

In another embodiment, more than two proximity sensors 50 may be disposed on the substrate under each side plate 42, for example, the proximity sensors 50 may be arranged on two straight lines under the tray front plate 43 and under the tray rear plate 44.

In another embodiment, as shown in fig. 10, the tray bottom plate 41 is preferably rectangular, a proximity sensor is disposed on the substrate under two corners of each tray bottom plate 41, and each proximity sensor 50 is disposed opposite to a third mounting hole 413 and/or a fourth mounting hole 414. The projection of the line connecting the two proximity sensors 50 below the tray bottom 41 on the tray bottom 41 is located on the diagonal of the tray bottom 41. Similarly, the positions of the proximity sensors 50 at the positions corresponding to the front tray panel 43 and the positions of the proximity sensors 50 at the positions corresponding to the rear tray panel 44 can be reversed in the manner shown in fig. 10, and the projection of the connecting line of the two proximity sensors 50 on the tray bottom panel 41 is also located on the diagonal line of the tray bottom panel 41.

In other embodiments, the proximity sensor 50 may also include a distance sensor, also known as a displacement sensor, such as an infrared ranging sensor, a laser ranging sensor, or an ultrasonic ranging sensor, among others. The computer system can detect the actual distance between the computer system and the side plate fixture block 421 through the distance sensor to determine the position of the tray side plate 42 remaining on the shelf, thereby calculating the position and width of the columns and finding out the position and number of the weight sensor corresponding to each column.

Each proximity sensor 50 is used for identifying one tray side plate, and in order to prevent the proximity sensor 50 from mistakenly identifying the other side plate card block 421 which is adjacent in position and has no corresponding relationship, a gap exists between any two adjacent trays 40, and the gap is more than or equal to the induction distance of the hall sensor by 10mm, so that the mistaken identification is avoided.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
