DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] refer to Figure 1 An automatic weighing vending machine 100 according to this embodiment includes a cabinet body 10 , a cabinet door 11 , a cargo channel 12 and a shelf module 20 .

[0041] One side of the cabinet 10 has an opening, and a cabinet door 11 is openably and closably arranged to cover the opening. Multi-layer cargo aisles 12 are arranged inside the cabinet 10 at intervals along the height direction.

[0042] The plurality of shelf modules 20 respectively have optional models for carrying material boxes 21 of different numbers and sizes. The shelf modules 20 of different optional models are all integrated with weighing sensors (not shown in the figure) and display screens 22 corresponding to the number of material boxes 21. The shelf modules 20 of different optional models are integrally assembled and disassembled in the corresponding cargo aisle 12 through openings.

[0043] Specifically, the weighing sensor is arranged on the layer module 20 and connected to the bottom of the material box 21, and is used to weigh the product in the material box 21. The display screen 22 is arranged on the side of the layer module 20 facing the opening and is located below the corresponding material box 21. The display screen 22 displays the product information in the corresponding material box 21, such as product type, inventory quantity, product weight and other information.

[0044] refer to Figure 1 As shown, in the present embodiment, each layer module 20 is respectively provided with 1, 2, 4, 6, and 10 material boxes 21, which are respectively assembled in the cargo aisle 12 from bottom to top, and each layer module 20 is integrated with weighing sensors and display screens 22 corresponding to the number of material boxes 21. By integrating the material boxes 21, weighing sensors and display screens 22 into the layer module 20, during assembly and subsequent maintenance and replacement, the staff only needs to carry the layer module 20 of the corresponding model, and can quickly complete the assembly and replacement by assembling and disassembling the entire layer module 20, which is convenient for maintenance and replacement, and effectively reduces the maintenance cost.

[0045] Understandably, Figure 1 The illustrated assembly form of the shelf module is merely an example, and the quantity and size of the material boxes 21 in each integrated shelf module 20 can be customized according to actual usage requirements. At the same time, the model of the shelf module 20 correspondingly arranged in each cargo aisle 12 can be determined according to actual usage requirements, and no specific restrictions are made here.

[0046] Furthermore, the cabinet 10 is usually required to be provided with an anti-dumping plate to prevent the cabinet from tipping over. However, the traditional anti-dumping plate is an integral iron bottom plate, which has the problems of heavy weight, high cost, and complicated installation.

[0047] In this embodiment, anti-dumping plates 14 are provided on both sides of the bottom of the cabinet 10 , and the anti-dumping plates 14 are extended along the assembly direction of the layer board module 20 .

[0048] Specifically, the length of the anti-dumping plate 14 is set to be longer than the depth of the cabinet 10. When the shelf module 20 is pulled out for maintenance, the center of the cabinet 10 will move forward. Since the front fulcrum of the extended anti-dumping plate 14 is far beyond the center of the forward movement of the cabinet 10, it can effectively prevent the cabinet 10 from tipping over and causing safety accidents when the shelf module 20 is pulled out for maintenance. The extended anti-dumping plate 14 can make the position of the cabinet 10 more stable.

[0049] Furthermore, each layer module 20 is provided with a layer controller (not shown in the figure), and the layer controller communicates and is electrically connected with the weighing sensor and display screen 22 corresponding to each material box 21 through a layer wiring harness.

[0050] A master controller 13 and a power supply module (not shown) electrically connected to the master controller 13 are also provided at the top of the cabinet 10. The master controller 13 communicates and is electrically connected to the layer controller corresponding to each layer module 20 via cables.

[0051] Specifically, the weighing sensors and display screens 22 corresponding to each material box 21 are uniformly connected to the layer controller through the layer board harness, and the master controller 13 is then electrically and communicatively connected to the layer controllers of each layer board module 20, which can effectively avoid cluttered lines. At the same time, the master controller 13 only needs to manage each layer controller, which effectively simplifies the system complexity and reduces the global communication load. In addition, the assembly, replacement or maintenance of a single-layer layer board module 20 will not affect the global operation, increasing the system reliability.

[0052] The communication protocol between the master controller 13 and the layer controller is the CAN protocol. When the layer controller of the layer module 20 is connected to the master controller 13, the master controller 13 can be notified through a CAN command that a new layer module 20 has been added, and the specific specifications of the new layer module 20 are provided, so that the new layer module 20 can be assembled and replaced without power failure and the automatic weighing vending cabinet 100 can be kept working normally.

[0053] Each layer module 20 is provided with a plug-in interface 23 of the layer wiring harness, and the master controller 13 is connected to the layer controller via the plug-in interface 23 of the layer wiring harness.

[0054] Specifically, when assembling or removing the layer board module 20 , the main controller 13 can be connected or disconnected with the layer controller through the plug-in interface 23 , realizing the plug-and-play of the layer board module 20 , and facilitating the rapid removal and assembly and replacement of the layer board module 20 .

[0055] In this embodiment, the automatic weighing vending machine 100 can also be provided with a face recognition component or a card swiping sensing component for opening the cabinet door 11, and correspondingly communicate with the main controller 13, thereby realizing face recognition or card swiping to open the door to collect the items inside the cabinet 10, and automatically recording the type and quantity of the products taken out and feeding back to the background.

[0056] refer to Figure 2 Each cargo aisle 12 includes a first lower rail 121 and a second lower rail 122 which are relatively arranged on both sides of the interior of the cabinet 10. A first upper limit plate 123 is arranged parallel to the top of the first lower rail 121, and a second upper limit plate 124 is arranged parallel to the top of the second lower rail 122. Both sides of the layer module 20 can be pulled out and arranged between the first lower rail 121 and the first upper limit plate 123, and between the second lower rail 122 and the second upper limit plate 124.

[0057] Further, refer to Figure 3Rollers 24 are provided on both sides of the bottom of the layer module 20, and the rollers 24 are located at the rear of the layer module 20. The rollers 24 are rotatably located on the upper surfaces of the first lower track 121 and the second lower track 122. The rollers 24 roll along the first lower track 121 and the second lower track 122 to assist in pulling and pulling the layer module 20.

[0058] refer to Figure 4 The first upper limit plate 123 and the second upper limit plate 124 are both provided with a clamp 125 , and the first upper limit plate 123 and the second upper limit plate 124 are both provided with a through hole 126 corresponding to the clamp head of the clamp 125 .

[0059] Specifically, the clamp 125 is a quick clamp, and the pressure head of the clamp 125 can be quickly controlled to press down or rise. When the pressure head of the clamp 125 is pressed down, it can be pressed down to the upper surface of the layer module 20 through the through hole 126, so as to press the layer module 20 to fix its position. The clamp 125 cooperates with the through hole 126 to fix the position of the layer module 20 assembled in the cargo channel 12, and prevent the layer module 20 from being damaged by front and rear collision when it is not fixed.

[0060] refer to Figure 5 , the opposite sides of the first lower rail 121 and the second lower rail 122 are provided with transverse limit columns 127, and the transverse limit columns 127 are arranged at the opening position close to the cabinet 10, and vertical limit columns 128 are arranged on both sides of the bottom end of the layer module 20 corresponding to the transverse limit columns 127, and the vertical limit columns 128 are arranged in the vertical direction near the rear end position of the material box 21.

[0061] Specifically, refer to Figure 6 Through the cooperation of the horizontal limit column 127 and the vertical limit column 128, a limit position is formed at the opening position close to the cabinet 10. After the shelf module 20 is pulled out to the limit position, the vertical limit column 128 is limited by the horizontal limit column 127 to prevent the shelf module 20 from continuing to move outward, thereby ensuring the stability of the position of the shelf module 20 after it is pulled out; at the same time, the part of the shelf module 20 where the material box 21 is provided can be exposed as a whole to the outside of the cabinet 10, which is convenient for adding and taking out products and for maintenance of components such as weighing sensors, layer controllers, display screens 22, and material boxes 21.

[0062] The first upper limit plate 123 and the second upper limit plate 124 are provided with a top gap corresponding to one end of the opening in the horizontal direction away from the transverse limit column 127, and the top gap provides redundant space for lifting the layer module 20 upward after being pulled out, and the vertical length of the redundant space is greater than the vertical limit column 128.

[0063] Specifically, after the layer board module 20 is pulled out to the limit position formed by the cooperation of the horizontal limit column 127 and the vertical limit column 128, the vertical limit column 128 is blocked by the horizontal limit column 127 and cannot be pulled out further. Figure 7 At this time, by lifting the layer board module 20, the vertical limit column 128 can be lifted to a position higher than the horizontal limit column 127 through the redundant space formed by the top gap of the first upper limit plate 123 and the second upper limit plate 124, and the layer board module 20 can be pulled out by moving outward synchronously, thereby realizing the rapid removal of the entire layer board module 20.

[0064] refer to Figure 8 The assembly method of an automatic weighing vending machine in this embodiment is used for the automatic weighing vending machine 100, and comprises the following steps:

[0065] In the step S1 of preparing the shelf module, a corresponding model of an integrated shelf module 20 is selected according to the aisle 12 to be assembled or the shelf module 20 to be replaced in the aisle 12 .

[0066] In the step S2 of assembling the layer board modules, the layer board modules 20 to be replaced are drawn out from the aisle 12 , or the prepared layer board modules 20 are directly assembled into the corresponding aisle 12 through the opening.

[0067] Specifically, the integrated layer board module 20 has different models, which respectively carry different numbers and sizes of material boxes 21, and are integrated with weighing sensors and display screens 22 corresponding to each material box 21. When assembling or replacing, the staff only needs to bring the corresponding model of the layer board module 20 to the site. When taking it out, unplug the connection cable connecting the main controller 13 to the plug-in interface 23 of the layer board harness, pull out the layer board module 20 originally assembled in the cargo channel 12 to the limit position, and then lift it up and continue to move it outward, so that the layer board module 20 can be quickly pulled out.

[0068] At the same time, during assembly, the pre-prepared shelf module 20 is pushed into the cargo aisle 12 through the opening, and the connecting cable of the main controller 13 is inserted into the plug-in interface 23 of the shelf wiring harness to complete the assembly. The shelf module 20 can be assembled and replaced quickly without powering off and maintaining the normal operation of the automatic weighing vending machine 100. The operation is simple and the maintenance cost is effectively reduced.

[0069] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
