< general Structure of Intelligent Cabinet >

Fig. 1 shows an intelligent cabinet 1 comprising a main control computer 4 with or connected to a display control panel 2 (hereinafter referred to as control panel 2) and a plurality of cabinet compartments 3 arranged side by side. Although not shown or to be described in detail later, various controllers, sensors, and the like for the respective cabinets 3 and the like are directly or indirectly connected to the control board of the main control computer 4 through wires. The background operating system of the main control computer 4 functions as a control system and can perform various settings through interaction with the operating screen 2.

Each compartment 3 has its interior closed off from the front by a compartment door 5 (front door) ( chambers 32, 33, see fig. 5), for which purpose an electromagnetic lock 56 (see fig. 3) is provided for each compartment door 5, for example. The electromagnetic lock is connected with a control panel in the main control computer 4 through a circuit and can act in response to the verification operation of a user.

Further, each cabinet 3 may be provided therein with a mechanism or an electric device for a heating function, a cooling function, a sterilizing function, a humidifying function, and the like, as required.

The leftmost set of upright cabinets illustrated in fig. 1 has an upper operating zone and a lower access zone. Two groups of vertical cabinets on the opposite right side are both access areas. The main body of the main control computer 4 is arranged in the upper control cabinet 7, and the middle of the front part of the main control computer is provided with a touch type operation screen 2 for carrying out interactive operation control with a distributor, such as a courier, a ordering user and other users. However, the vertical and horizontal type, the number of sets, and the arrangement of the cabinets are not limited thereto.

Accordingly, fig. 2 shows a rear side view of the smart cabinet 1, with a plurality of cabinets 3 likewise enclosing their interior from the rear side by means of an electromagnetic lock via cabinet doors 55 (rear doors).

Although only the compartment door 6 of the control cabinet 7 is schematically shown in fig. 2, a rear user-facing control panel may also be provided there, or other associated input and scanning terminals may be connected, and an AI smart recognition camera 22 as shown in fig. 1 may also be provided.

Therefore, the intelligent cabinet 1 according to the embodiment can be used for storing and taking fast food, can sterilize the cabinet body and the fast food, can be used in places such as fast food restaurants and schools, and can realize contactless delivery by placing food on one side of the cabinet body and taking food from the other side. Similarly, the intelligent cabinet can be suitable for wide spaces of banks, business halls and the like, is suitable for forming space partitions by utilizing the cabinet body of the intelligent cabinet, issues or delivers files from one side, and extracts files from the other side. The utility model can also be applied to the partition wall of the supermarket, goods are loaded at the back side, and the goods are selected by the consumers at the front side.

During operation, a storage service can be initiated at the rear side by using an operation screen and the like, a background operation system of the main control computer 4 allocates the free cabinet grids 3, the cabinet grid door 55 is opened, and the door closing operation is performed after the storage is finished.

Then, the user who receives the extraction notice can carry out verification operation according to the storage information, open the cabinet compartment door to take away the articles, and carry out door closing operation. Or, in a supermarket scene, the consumer directly performs door opening purchasing operation through conventional code scanning verification and the like.

Therefore, the cabinet body can effectively separate the personnel of the two parties for storage and taking, and the possibility of disorder, close distance and even contact of the personnel mixed together for storage and taking is avoided.

< automatic door closing apparatus >

In order to further embody the contactless function, according to the present invention, an automatic door opening and closing mechanism is further provided for at least one of the shelf doors 3 and 55. For the sake of brevity, the following description will be made by taking a partial cabinet shown in fig. 3 as an example.

Figure 3 shows three adjacent compartments above and below in a set of upright cabinets. Each of the compartment doors 5 is provided with a rotating shaft sleeve 52 (or bearing) at a side edge of the cabinet body, one side of which is fixedly connected to the compartment door 5 through a connecting portion 51, and a main body of which is sleeved on the pivot shaft 10 through a hollow sleeve 53 and can rotate around the pivot shaft.

The pivot 10 is likewise pivotably passed through a sleeve (not shown) fixed to the cabinet side. The compartment doors 5 share a common pivot 10.

The pivot 10 may be fixed with a projection 16 for electromagnetic coupling via a coupling member (e.g., a screw or a spline).

During installation, the pivot 10 passes through the uppermost first set of sleeves and sleeves 53 (the upper and lower positions of the sleeves and sleeves are not limited), then passes through the second set of sleeves and sleeves, and then passes through the collar 54 for keeping the height of the cabinet doors and the interval between the cabinet doors until reaching the lowermost set of sleeves and sleeves. Here, the two sleeves 53 and sleeves are illustrated as being provided for each door, but the present invention is not limited thereto.

Then, the fixing portion 160 on the side of the projection 16 is fastened to the pivot 10 with a screw. The other side is preferably formed with a curved magnetic attachment portion 161. So as to be joined to the preferably curved surface of the magnetic tongue portion 141 of the electromagnetic portion 14 provided in each of the compartment doors 5.

An energizing coil (not shown) is arranged in the base 140 of the electromagnetic part 14, and the magnetism generated when the electromagnet is energized is the same as the magnetism on the opposite side of the magnetic tongue part 141, so that the pushing force is generated on the magnetic tongue part 141, and the deformation of the magnetic tongue part is moved towards the magnetic part 161 against the pulling force of the spring 142 until the magnetic part is in adsorption joint.

A worm 12 for driving a worm wheel 11 on one end side of the pivot shaft 10 is provided on the top 31 side of the cabinet frame and is rotated by a motor 13. The transmission mechanism or the reduction mechanism of the pivot 10 is not limited thereto.

When the electromagnetic lock of a certain compartment door 5 receives an opening command to unlock and the door is bounced open (a conventional torsion spring may be provided here), the electromagnetic part 14 also energizes the energizing coil at the same time or subsequently, and the tongue part 141 and the magnetic part 161 are joined together. The motor 13 starts to drive the worm 12 to rotate, which drives the worm wheel 11 and thus the pivot 10. At the same time, the magnetic part 161 fixedly connected to the pivot 10 and the tongue 141 rotates along with the pivot 10, and drives the compartment door 5 to rotate to a proper stop position in the direction of continuing to open the door.

When the AI intelligent camera 22 or other photoelectric sensors, or a time delay relay, etc. are used to determine that the user has left the door and can safely close the door, the motor 13 rotates in the reverse direction to drive the compartment door 5 to rotate in the door closing direction until the electromagnetic lock is touched to close the door. At this time, the energizing coil is deenergized, and the tongue 141 is disengaged from the magnetic connection portion 161 and is returned by the tensile force of the spring 142.

In this process, in other compartment doors which are not opened during the closing operation, the electromagnetic section 14 cannot receive the energizing operation signal, and therefore the tongue section 141 cannot be engaged with the pivot shaft 10, and the above-described automatic door opening and closing operation cannot be performed.

In addition, when the stock inventory and cleaning operation is performed, for example, a plurality of desired compartment doors can be automatically opened and closed at the same time by one-key door opening device or operation of the main control computer 4, which is very convenient.

The connection length w1 of the connection portion 51 and the corresponding width w2 of the projection 16 shown in fig. 4 can be set appropriately according to the sheet metal and the aesthetic property of the cabinet door.

The set of door opening and closing mechanisms illustrated above is provided with one pivot 10 for all the cabinet lattices in a group, but is not limited thereto, and may be divided into a plurality of pivots 10 and matching transmission mechanisms as long as the pivot is appropriately hidden on the cabinet frame, or even a set of door opening and closing mechanisms is provided for a single cabinet lattice. Furthermore, it may be provided on the front and/or rear compartment doors, preferably both front and rear sides, to enable contactless operation of both sides with respect to the compartment doors.

< separate article-taking device >

The individual fetching device shown in fig. 5-8 is particularly suitable for the pick-up scene such as a supermarket. The following description will be given by taking the beverage bottle 101 as an example, but it is needless to say that the beverage bottle is not limited thereto, and may be a box for storing documents and the like.

The double-door intelligent cabinet provided by the invention provides a supermarket with a choice of being used as a partition wall or a cabinet window wall, so that the capacities of all the cabinet bodies can be arranged differently according to the sizes of goods, and the function of automatic vending is realized.

In at least one cabinet 3, in addition to the lower chamber 32 for arranging the driving motor 36 (even the weighing sensor 35, the time delay sensor, etc.), a plurality of, for example, 3 conveyor belts 91, 92, 93 are provided on the floor side of the upper chamber 33, and the beverage bottles 101 are conveyed to the rotary table 8 by the control of the main control computer 4.

The top side of the rotary table 8 may be fixedly mounted in the upper chamber 33 by means of a bracket 71, for example. The top is rotatably supported to bracket 71 by bearing portion 73, and the base 72 of bracket 71 is attached to the upright or top wall of upper chamber 33.

Accordingly, the base side of the rotary table 8 may be attached to the bottom side wall of the upper chamber 33 by a bearing or the like, and rotated about the rotary shaft 88 by the motor 36, thereby rotating the beverage bottles 101 dispensed thereon.

The rotary table 8 and the bracket 71 are preferably constructed as an attachment assembly for later installation in the upper chamber 33.

Each beverage bottle 101 is placed in a plurality of cargo spaces 81-84 partitioned by a partition plate on the rotary table 8. The beverage bottle 101 at only one of the product positions (e.g., product position 84 shown in fig. 6) is available at the access position 100 because the left side (illustrated here as the side near the pivot 10) is obscured by the flap 34 at the bay door opening.

When a consumer scans the two-dimensional code on the cabinet grid door, and after the number of the goods is selected and the goods is paid by utilizing software such as a small program, the background operating system instructs the electromagnetic lock to unlock, the cabinet grid door is opened, and the consumer can take away the upper beverage bottle 101 of the goods space 81.

At this time, the weighing sensor 35 feeds back information to the background operating system to start the motor 36 to drive the rotating platform 8 to rotate by one cargo space position, so that the next cargo space 84 reaches the pick-up position 100 to continue to supply. The system also supports the scenario where the consumer picks up multiple items at once. When the consumer pays for the goods on the selected goods space, the rotation of the rotary table 8 is prohibited until the door is closed.

At this time, the position 81 rotating one position toward the downstream side is adjacent to the conveyor belt 91, and the back-end operating system instructs the driving motor 87 to operate, so that the beverage bottle 101 on the conveyor belt 91 moves toward the front side, and when the beverage bottle reaches a predetermined position, the push rod 86 pushes the beverage bottle 101 to the position 81.

When the beverage bottle 101 on the conveyor belt 91 is used up, the background operating system obtains information through the induction sensor, and instructs the second conveyor belt 92 to operate, and sends warning information to the supplier for goods feeding notification until no goods are available on the third conveyor belt 93.

As shown in fig. 8, it is preferable that a guide portion 341 is further connected to the inside of the inner wall 342 of the baffle 34, and the curved surface thereof serves to guide and push the beverage bottle 101.

Thus, when the cabinet door is opened and the goods are taken from the goods position at the goods taking position 100, the main control computer 4 judges that the rotary goods shelf needs to be rotated to continue supplying goods based on the verification information before the cabinet door is opened, and instructs the rotary driving system to rotate the rotary goods shelf based on the information change updated by the weighing sensor, so that the next goods position is rotated to the goods taking position 100; and when the continuous supply of goods is judged to be required to be stopped, the rotary driving system is prohibited from rotating the rotary goods shelf and waits until the door closing action is completed, the rotary driving system is instructed to rotate the rotary goods shelf, so that the next goods position is rotated to the goods taking position 100.

Therefore, according to the present invention, there is also provided an automatic supply method for a double-door intelligent cabinet, comprising the steps of:

s1: the user scans the two-dimensional code or inputs the verification code for verification;

s2: when the user passes the correct verification, the electromagnetic lock is controlled to open the corresponding cabinet grid door;

s3: at the moment or later, starting the door opening action of the automatic door closing device to a preset stop position;

s4: the user removes the item from the compartment not obscured by the barrier 34;

s5: when the master control computer judges that the goods need to be supplied continuously based on the verification information before the cabinet compartment door is opened, the master control computer instructs to continuously rotate the rotary goods shelf, so that the next goods position is rotated to the goods taking position 100; when the continuous supply is judged to be required to stop, the rotary shelf is prohibited to rotate;

s6: after the user leaves the pickup position 100 for a predetermined time and confirms safety, the automatic door opening and closing device starts a door closing operation;

s7: when the electromagnetic lock is locked, the automatic door opening and closing device finishes the door closing action, namely the electrified coil is disconnected, and the magnetic tongue portion 141 is separated from the lug 16;

s8: after the door closing action is completed, the main control computer 4 instructs the driving motor to rotate the rotary shelf, so that the next cargo space is rotated to the pickup position 100.

Wherein, after the step S8, a step S9 may be further included: the empty cargo space just left by the removal of the article is replenished by a conveyor (conveyor belt 91) provided adjacent to the rotary shelf.

Wherein, after the step S9, a step S10 may be further included: after emptying the goods on the first conveyor, the empty goods space is filled with goods by means of a further conveyor (conveyor belts 92, 93) arranged next to each other.

Therefore, the worry of the conventional mistaken contact, the malicious contact and the like can be eliminated, the goods can be taken one by one according to the requirement, and the goods can be supplemented and the goods shortage can be informed in time.
