[0002] Self-service vending machines are commonly used equipment for commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as 24-hour mini supermarkets. And with the changes in the market, vending machines have also appeared in various styles, including vending machines that sell pizza, etc.

[0003] The self-service pizza machine needs to place the pizza in a pizza box and then put it in a storage device for refrigeration or freezing, so as to maintain the quality of the pizza for a long time. When in use, the pizza is taken out of the storage device by the handling device and sent to the box opening device. The box opening device positions the pizza box through the positioning mechanism, and the lifting mechanism drives the box opening frame to open the pizza box. The conveying mechanism sends the pizza in the pizza box to the heating device for heating. After the heating is completed, the conveying mechanism takes out the pizza, puts it back into the pizza box and sends it to the delivery port.

[0004] The existing box body positioning mechanism mainly fixes one side of the pizza box by setting a fixing plate on one side and driving a flip plate on the other side with a motor, so as to position the pizza box by opposite fixing. When the pizza box is transferred from the storage device to the box opening device, it is inevitable that the box body will tilt, and the positioning method on both sides may cause the front and rear sides of the pizza box at the box opening device to deviate, resulting in the box opening frame being unable to open the pizza box smoothly, and even the box opening frame flipping the pizza box when it rises.

[0005] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Utility Model Content

[0038] Example 1

[0039] See Figure 1-6 As shown, the box positioning mechanism includes a frame 1, at least two positioning components 2, a driving mechanism 3 and a guide plate 4. The positioning component 2 and the driving mechanism 3 are respectively installed on the frame 1, and the guide plate 4 is installed on the output end of the driving mechanism 3. When positioning the pizza box, the driving mechanism 3 drives the positioning component 2 to move inward through the guide plate 4. The utility model limits the four sides of the pizza box through the positioning component 2, so that the pizza box is always kept in the middle position, avoiding errors when the box opening frame opens the pizza box. It should be noted that the number of positioning components 2 of the utility model is 4. When positioning the pizza box, the corresponding driving mechanism 3 drives the four positioning components 2 to close inward through the guide plate 4 to limit the position of the pizza box.

[0040] In a further specific embodiment, the guide plate 4 is provided with guide grooves 41 corresponding to the number of the positioning components 2. The guide grooves 41 are in the shape of an arc. By setting the guide grooves 41, when the driving mechanism 3 drives the guide plate 4 to rotate, the limiting end of the positioning component 2 can be pushed to move, thereby realizing the positioning of the pizza box. It should be noted that the number of positioning components 2 in this embodiment is 4, so the number of guide grooves 41 is also 4, and the positioning ends of the 4 positioning components 2 extend into the guide grooves 41 respectively. The arc-shaped guide grooves 41 can better drive the positioning ends of the positioning components 2 to move more smoothly. In other specific embodiments, the shape of the guide grooves 41 can also be linear, but this shape will have certain setbacks when moving compared to the present embodiment, and the wear on the guide grooves 41 is also greater.

[0041] It should be noted that, in this embodiment, when positioning the pizza box, the positioning end of the positioning assembly 2, i.e., the positioning member 22, moves in the guide groove 41 and gradually approaches the center position of the guide plate 4. When the pizza box needs to be released, the positioning member 22 gradually moves away from the center position of the guide plate 4 in the guide groove 41.

[0042] In a further specific embodiment, the guide plate 4 is provided with a through slot 42 for passing the box opening frame. The through slot 42 enables the box opening frame to pass through the through slot 42 to open the pizza box. The structure is simple and practical.

[0043] In a further specific embodiment, the positioning assembly 2 includes a mounting frame 21 and a positioning member 22 , the mounting frame 21 is mounted on the frame body 1 , the bottom of the positioning member 22 is slidably mounted on the mounting frame 21 , and the top of the positioning member 22 extends into the guide plate 4 .

[0044] In a further specific embodiment, the positioning assembly 2 further includes a guide assembly 23, the guide assembly 23 includes a guide column 231 and a guide block 232, the guide column 231 is mounted on the mounting frame 21, the guide block 232 is slidably mounted on the guide column 231, and the bottom of the positioning member 22 is mounted on the guide block 232. Through this arrangement, the positioning member 22 can move on the guide column 231 through the guide block 232, and the arrangement of the guide column 231 and the guide block 232 can guide the movement of the positioning member 22, reduce the force of the driving mechanism 3 to drive the positioning member 22 to move, and make the movement of the positioning member 22 smoother.

[0045] It should be noted that an anti-slip member is provided at the end of the positioning member 22 of this embodiment, that is, the position in contact with the pizza box.

[0046] In a further specific embodiment, the driving mechanism 3 includes a rotating motor 31 and a main shaft 32, the output end of the rotating motor 31 is connected to the first end of the main shaft 32, and the guide plate 4 is connected to the second end of the main shaft 32. It should be noted that a transmission mechanism is also provided between the rotating motor 31 and the main shaft 32 of this embodiment, and the transmission mechanism can be added according to actual use needs, or the output shaft of the rotating motor 31 can be directly connected to the main shaft 32 without providing a transmission mechanism.

[0047] In a further specific embodiment, a lifting mechanism 5 is also included, the frame 1 includes a mounting seat 11, a mounting plate 12 and a fixing plate 13, the driving mechanism 3 and the lifting mechanism 5 are respectively installed on the mounting seat 11, the positioning assembly 2 is installed on the mounting plate 12, and the output end of the lifting mechanism 5 is connected to the mounting plate 12. The positioning assembly 2 is driven to lift and lower through the setting of the lifting mechanism 5, so that the positioning member 22 of the positioning assembly 2 can be located in the middle of the pizza box, so as to better position the pizza box. It should be noted that according to actual needs, the positioning of the pizza box can be achieved by pushing the positioning member 22 to a position beyond the bottom of the pizza box.

[0048] At the same time, when the pizza box does not need to be fixed, the lifting mechanism 5 can directly drive the positioning member 22 to descend to the highest point of the positioning member 22 below the fixing plate 13, so as to avoid a certain impact on the delivery of the pizza box. The fixing plate 13 is provided with a through hole 131 for passing the positioning assembly 2 and the box opening rack. Through the provision of the through hole 131, the positioning assembly 2 and the box opening rack can pass through the fixing plate 13 to fix and open the pizza box.

[0049] In a further technical solution, a guide column 111 is provided on the mounting seat 11, a guide seat 121 is provided on the mounting plate 12, and the guide column 111 passes through the guide seat 121 and is connected to the fixing plate 13. By providing the guide column 111 and the guide seat 121, the resistance of the mounting plate 12 to rise and fall is reduced, the structure is simple, and the practicability is strong.

[0050] It should be noted that the positioning member 22 of the utility model is a cylindrical positioning rod. This setting can better move in the guide groove 41. In addition, when the box body positioning mechanism of the utility model is not positioning the pizza box, there are no other parts on the surface of the fixed plate 13 except the pizza box. Therefore, after the pizza is heated and put back into the pizza box, the box opening rack and the positioning mechanism return to the origin, and the pizza box can be directly moved on the fixed plate 13. At this time, the pizza box can be directly pushed from the fixed plate 13 to the delivery port through the pizza transport mechanism.

[0051] The working principle of the utility model is as follows: when the pizza box needs to be positioned, the lifting mechanism 5 pushes the mounting plate 12 upward and pushes the positioning member 22 to the middle of the pizza box. Then the driving mechanism 3 drives the guide plate 4 to rotate through the main shaft 32. Under the guidance of the arc-shaped guide groove 41 of the guide plate 4, the four positioning members 22 gradually approach the pizza box together until the pizza box is clamped. At this time, the positioning member 22 is located at one end of the guide groove 41 close to the middle position of the guide plate 4. When resetting is required after positioning is completed, the driving mechanism 3 drives the guide plate 4 to rotate in the opposite direction again through the main shaft 32. Under the guidance of the arc-shaped guide groove 41 of the guide plate 4, the four positioning members 22 gradually move away from the pizza box together until they return to the origin. At this time, the lifting mechanism 5 pushes the mounting plate 12 to drive the positioning assembly 2 to move downward together until the top of the positioning member 22 is lower than the top of the mounting plate 12.
