Description

Technical Field

[0001] The utility model relates to the technical field of vending machines, in particular to a lifting mechanism and a vending machine. Background Art

[0002] A vending machine is a commonly used device for commercial automation. It is not restricted by time and location, can save manpower and facilitate transactions. It is a brand-new form of commercial retail and is also known as a 24-hour mini supermarket.

[0003] The lifting mechanism of the existing vending machine uses a weighing mechanism to sense the weight of the picking mechanism. When a user purchases a commodity, the lifting mechanism drives the picking mechanism to move to the goods channel where the commodity is located. The commodity then enters the picking mechanism from the goods channel. The weighing mechanism in the picking mechanism senses the weight change, indicating that a commodity has fallen into the picking mechanism. At this time, the lifting mechanism drives the picking mechanism to move to the delivery port for the user to pick up the goods.

[0004] Since the temperature in a vending machine with refrigeration or freezing function is relatively low, and the picking mechanism often moves to the delivery port, resulting in a relatively high temperature of the picking mechanism. Under the condition of alternating hot and cold in the vending machine, water droplets will condense on the picking mechanism, and the sensing end of the weighing mechanism and the picking mechanism are connected by water droplets and solidify, resulting in the weighing mechanism being unable to sense the weight change.

[0005] In view of this, a new technical solution is needed to solve the above technical problems. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a lifting mechanism and a vending machine to solve the problems raised in the background art.

The mounting frame and the driving mechanism are respectively installed on the main cabinet of the vending machine. The picking mechanism is slidably installed on the mounting frame. The output end of the driving mechanism is connected to the picking mechanism. The picking mechanism includes a weighing mechanism, a mounting seat, and a tray. The mounting seat is slidably installed on the mounting frame. The weighing mechanism is installed on the mounting seat. The tray is installed on the sensing end of the weighing mechanism. A through groove is formed in the mounting seat, and the through groove is arranged below the sensing end of the weighing mechanism.

[0012] In a further technical solution, the second support plate is provided with fixing holes, and fixing bolts are arranged in the fixing holes. The fixing bolts penetrate through the second support plate and are screwed to the tray.

[0013] In a further technical solution, the mounting seat is provided with a receiving cavity for receiving the tray, the weighing mechanism is installed in the receiving cavity, and a bracket is formed by the inward extension of the side wall of the receiving cavity. The height of the bracket is lower than the height of the weighing mechanism.

[0034] Embodiment 1

[0035] See Figures 1-5As shown, the lifting mechanism includes a mounting frame 1, a driving mechanism, and a goods picking mechanism 2. The mounting frame 1 and the driving mechanism are respectively installed on the main cabinet of the vending machine. The goods picking mechanism 2 is slidably installed on the mounting frame 1. The output end of the driving mechanism is connected to the goods picking mechanism 2. The goods picking mechanism 2 includes a weighing mechanism 21, a mounting seat 22, and a tray 23. The mounting seat 22 is slidably installed on the mounting frame 1. The weighing mechanism 21 is installed on the mounting seat 22. The tray 23 is installed on the sensing end of the weighing mechanism 21. The mounting seat 22 is provided with a through groove 221, and the through groove 221 is arranged below the sensing end of the weighing mechanism 21. Through the arrangement of the through groove 221, the sensing end of the weighing mechanism 21 is in a suspended state. When water drops solidify at the bottom of the sensing end of the weighing mechanism 21, it will not affect the weighing mechanism 21. The structure is simple and convenient to use. It should be noted that in this embodiment, the mounting seat 22 is provided with a plurality of through grooves 221. The through groove 221 can, on the one hand, make the sensing end of the weighing mechanism 21 in a suspended state, and on the other hand, can reduce the weight of the mounting seat 22, reduce its weight, and reduce the wear of the driving mechanism.

[0036] In a further specific embodiment, the mounting seat 22 is provided with a first support plate 222, and the weighing mechanism 21 is installed on the first support plate 222. By means of the first support plate 222, the height between the weighing mechanism 21 and the mounting seat 22 is increased, avoiding contact between other parts of the weighing mechanism 21 and the mounting seat 22.

[0037] In a further specific embodiment, a second support plate 223 is arranged at the bottom of the tray 23, and the second support plate 223 is installed above the sensing end of the weighing mechanism 21. Through the arrangement of the second support plate 223, the sensing area of the sensing end of the weighing mechanism 21 is enlarged, and the sensing surface of the sensing end of the weighing mechanism 21 is enlarged from a point to a surface.

[0038] In a further specific embodiment, the tray 23 is provided with a mounting hole 231, and a connecting bolt 232 is arranged in the mounting hole 231. The connecting bolt 232 sequentially passes through the mounting hole 231 and the second support plate 223 and is connected to the weighing mechanism 21. The diameter of the mounting hole 231 is larger than the diameter of the head of the connecting bolt 232. The number of the weighing mechanisms 21 is two, and the two weighing mechanisms 21 are respectively arranged at both ends of the mounting seat 22. The mounting seat 22 is respectively provided with a through groove 221 below the sensing end of each weighing mechanism 21. The second support plate 223 is provided with a fixing hole, and a fixing bolt is arranged in the fixing hole. The fixing bolt passes through the second support plate 223 and is screwed to the tray 23.

[0039] Through this setting, the weighing mechanism 21 does not directly contact the tray 23, but is transferred through the second support plate 223. A soft connection state is formed between the two weighing mechanisms 21, avoiding errors in weighing caused by rigid connection to the weighing mechanism 21.

[0040] It should be noted that when there is a rigid connection between the two weighing mechanisms 21, that is, when the two weighing mechanisms 21 are directly installed at the bottom of the tray 23 respectively, if a commodity falls to one end of the tray 23, the tray 23 will tilt, causing one of the weighing mechanisms 21 to be stressed, thereby pulling the other weighing mechanism 21 to be stressed as well, affecting the weighing data.

[0041] It can be understood that the diameter of the stud of the connecting bolt 232 is smaller than the diameter of the connecting hole on the second support plate 223, that is, there is a certain gap between the connecting bolt 232 and both the second support plate 223 and the tray 23. Therefore, a soft connection state exists between the two weighing mechanisms 21. When a commodity falls to one end of the tray 23, one of the weighing mechanisms 21 is stressed and will not pull the other weighing mechanism 21, and the weighing data will not be affected.

[0042] In a further specific embodiment, the mounting seat 22 is provided with a receiving cavity 224 for receiving the tray 23. The weighing mechanism 21 is installed in the receiving cavity 224, and the side wall of the receiving cavity 224 extends inwards to form a bracket 225. The height of the bracket 225 is lower than the height of the weighing mechanism 21. The tray 23 is protected by the receiving cavity 224 so that the tray 23 is always within the receiving cavity 224. At the same time, through the setting of the bracket 225, the bottom of the tray 23 is limited, preventing the commodity from being too heavy and causing one end of the tray 23 to drop excessively, affecting the accuracy of the weighing mechanism 21.

[0043] In a further specific embodiment, a plurality of reinforcing ribs 233 are provided at the bottom of the tray 23. Through the setting of the reinforcing ribs 233, the strength of the tray 23 is enhanced, with a simple structure and strong practicability.
