Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, specifically to a vending machine jam alarm device. Background Technology

[0002] A vending machine is a machine that automatically dispenses goods based on the amount of money inserted. Vending machines are commonly used equipment in commercial automation. They are not limited by time or location, saving manpower and facilitating transactions. They represent a new form of commercial retail, also known as a 24-hour mini-supermarket. Common vending machines are divided into four types: beverage vending machines, food vending machines, general merchandise vending machines, and cosmetics vending machines.

[0003] However, existing vending machines have the following drawbacks: during the product transportation and dispensing process, existing vending machines are prone to jamming. That is, when the product is being dispensed from the locker, if the product is too large, it may get stuck between the locker and the glass window before it falls, thus preventing the product from falling normally. In response, we have proposed a vending machine jamming alarm device to solve the above-mentioned problem. Utility Model Content

[0004] The purpose of this invention is to provide a vending machine jam alarm device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vending machine jam alarm device, comprising:

[0006] The vending machine body has a cabinet door hinged to the front of its storage compartment. A rectangular through-slot is provided on the cabinet door, within which a movable display window is located. Two fixed seats are welded to the inner wall of the cabinet door near the top. A bidirectional lead screw is rotatably mounted between the two fixed seats. A servo motor is fixedly mounted on one of the fixed seats, and the output end of the servo motor is connected to the bidirectional lead screw. Two symmetrically arranged movable seats are threaded onto the bidirectional lead screw. A first rotating column is fixedly welded to the bottom wall of each movable seat. Two fixed blocks are fixedly welded to the top of the movable display window. A second rotating column is fixedly welded to the top wall of each fixed block. A connecting rod is rotatably mounted on the second rotating column, with the end of the connecting rod furthest from the second rotating column rotatably mounted on the corresponding first rotating column.

[0007] Preferably, two pairs of fixing rods are fixedly welded to the inner wall of the cabinet door, and the two pairs of fixing rods are respectively set on both sides of the movable display window. A pair of sliders are fixedly welded to both sides of the movable display window, and the sliders have openings, in which the fixing rods are slidably connected.

[0008] Preferably, an operation touch screen panel is fixedly installed on the main body of the vending machine, and a jam handling switch is provided on the operation touch screen panel. The jam handling switch is electrically connected to the servo motor through a PLC controller.

[0009] Preferably, a baffle is fixedly welded to the front side wall of the cabinet door.

[0010] Preferably, the movable display window is equipped with a transparent observation window.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In use, when goods get stuck between the storage cabinet and the transparent observation window during transportation and unloading, pressing the jamming switch will activate the PLC controller to start the servo motor and drive the bidirectional lead screw to rotate forward. When the bidirectional lead screw rotates forward, it will cause two moving seats to move towards each other on the bidirectional lead screw, thereby causing the two connecting rods to flip and push the movable display window to slide forward in the rectangular through groove of the cabinet door. This increases the distance between the transparent observation window and the storage cabinet of the vending machine, allowing the stuck goods to fall smoothly and ensuring the normal unloading of the goods.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a vending machine jam alarm device, comprising:

[0019] The vending machine body 1 has a cabinet door 2 hinged to the front of its storage compartment. The cabinet door 2 has a rectangular through groove 3, and a movable display window 4 is provided in the rectangular through groove 3. Two fixed seats 5 are fixedly welded to the inner wall of the cabinet door 2 near the top. A bidirectional lead screw 6 is rotatably installed between the two fixed seats 5. A servo motor 7 is fixedly installed on one of the fixed seats 5. The output end of the servo motor 7 is connected to the bidirectional lead screw 6. Two symmetrically arranged movable seats 8 are threadedly connected to the bidirectional lead screw 6. A first rotating column 9 is fixedly welded to the bottom wall of the movable seat 8. Two fixed blocks 10 are fixedly welded to the top of the movable display window 4. A second rotating column 11 is fixedly welded to the top wall of the fixed block 10. A connecting rod 12 is rotatably installed on the second rotating column 11. The end of the connecting rod 12 away from the second rotating column 11 is rotatably installed on the first rotating column 9 at the corresponding position.

[0020] Two pairs of fixing rods 13 are fixedly welded to the inner wall of the cabinet door 2. The two pairs of fixing rods 13 are respectively set on both sides of the movable display window 4. A pair of sliders 14 are fixedly welded to both sides of the movable display window 4. The sliders 14 have openings 15. The fixing rods 13 are slidably connected in the openings 15. By sliding the sliders 14 and the fixing rods 13 together, the movable display window 4 can be supported and positioned.

[0021] An operation touch screen panel 16 is fixedly installed on the main body 1 of the vending machine. A jam handling switch 17 is provided on the operation touch screen panel 16. The jam handling switch 17 is electrically connected to the servo motor 7 through a PLC controller. The operation touch screen panel 16 is used for purchasing goods, and the jam handling switch 17 is used to start the servo motor 7.

[0022] A baffle 18 is fixedly welded to the front side wall of the cabinet door 2. The baffle 18 is used to block the gap at the bottom when the movable display window 4 moves forward.

[0023] The movable display window 4 is equipped with a transparent observation window 19, which is used to observe the condition of the goods inside the vending machine.

[0024] Working principle: During use, when goods get stuck between the storage cabinet and the transparent observation window 19 during transportation and unloading, pressing the jamming switch 17 will cause the PLC controller to start the servo motor 7 and drive the bidirectional lead screw 6 to rotate forward. When the bidirectional lead screw 6 rotates forward, it can drive the two moving seats 8 to move towards each other on the bidirectional lead screw 6, thereby causing the two connecting rods 12 to flip and push the movable window 4 to slide forward in the rectangular through groove 3 of the cabinet door 2, increasing the distance between the transparent observation window 19 and the vending machine's storage cabinet, so that the stuck goods can fall smoothly. When the movable window 4 moves forward to a certain position, the PLC controller will stop the servo motor 7 and drive the bidirectional lead screw 6 to rotate in the opposite direction until the movable window 4 is reset.
