Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending machines, in particular to a rotating mechanism, a transport device and a self-service pizza machine. Background Art

[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 places the pizza in a pizza box and then puts it in a storage device for refrigeration or freezing, thereby maintaining the quality of the pizza for a long time. When in use, the pizza is taken out of the storage device by the transport device and sent to the heating device for heating. After heating, the pizza is sent to the delivery port.

[0004] The handling device of the existing self-service pizza machine mainly picks up the pizza box through the material picking mechanism, that is, the Z-axis moving mechanism drives the material picking pallet to extend into the storage device and be placed at the bottom of the pizza box. After the pizza box is lifted up, it is withdrawn from the storage device and moved to the heating device, and then the pizza box is pushed from the side into the heating device through the lever set on one side of the pallet.

[0005] The method of transferring pizza boxes by the support plate and the lever is less stable. When the lever pushes the pizza box into the heating unit, the lever is driven by the driving motor to move. One end of the lever is connected to the transmission belt, and the other end pushes the pizza box. The lever is subjected to force on one side and is subject to greater wear. The lever will bend after long-term use. Moreover, the support plate of the prior art is usually composed of several fork rods with a large gap in the middle. When the lever pushes the pizza box to move, the pizza box is prone to shaking, causing the pizza box to fall.

[0006] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0007] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a rotating mechanism, a transport device and a self-service pizza machine to solve the problems raised in the background technology.

The limiting assembly is provided to limit the rotation angle of the fixing seat driven by the driving mechanism, thereby preventing the rotation angle from being too large, causing the pizza box to be stuck outside the heating unit when the pizza box is transferred.

[0010] In a further technical solution, the limit assembly includes a limit member and a limit plate, the limit member is mounted on the fixed seat, the limit plate is mounted on the mounting seat, and when the rotating mechanism rotates to a specified angle, the limit member abuts against the limit plate. The rotation angle of the fixed seat is limited by the cooperation of the limit plate and the limit member to avoid excessive rotation angle, which causes the pizza box to be stuck outside the heating unit when the pizza box is transferred. The structure is simple and the rotation accuracy of the rotating mechanism is enhanced.

[0011] In a further technical solution, the limit plate has a limit groove, the limit groove forms a rotation path, the first end of the limit member is connected to the fixed seat, and the second end of the limit member extends into the limit groove.

[0016] When the rotating mechanism rotates to a specified angle, the switch paddle touches the limit switch. The limit switch and the switch paddle are used to limit the angle at which the rotating mechanism drives the fixing seat to rotate. When the switch paddle touches the limit switch, the rotating mechanism stops rotating.

[0017] In a further technical solution, the mounting seat is installed with a mounting plate, the mounting plate has a mounting groove, the limit switch is installed in the mounting groove, the switch paddle is installed at the bottom of the fixing seat, the driving mechanism is installed on the mounting plate, the output end of the driving mechanism passes through the mounting plate and the mounting seat and is connected to the fixing seat, and when the rotating mechanism rotates to a specified angle, the switch paddle touches the limit switch. By setting the mounting groove, the limit switch is installed in the mounting groove, the space between the mounting seat and the fixing seat is reduced, the structure is simple, and the practicability is strong.

[0046] Example 1

[0047] See Figure 1-4 As shown, the rotating mechanism includes a driving mechanism 1, a mounting seat 2 and a fixed seat 3 for mounting a Z-axis moving mechanism 6. The driving mechanism 1 is mounted on the mounting seat 2. The output end of the driving mechanism 1 passes through the mounting seat 2 and is connected to the fixed seat 3, so as to drive the fixed seat 3 to rotate. It should be noted that the driving mechanism 1 of the utility model uses a rotating motor. When the pizza box 8 is transferred to the heating unit, the fixed seat 3 is driven to rotate by the driving mechanism 1, so that the Z-axis moving mechanism 6 and the material-taking mechanism 7 are respectively directed toward the heating unit. The transport device brings the Z-axis moving mechanism 6 and the material-taking mechanism 7 into the heating unit with the pizza box 8. After the material-taking mechanism 7 releases the pizza box 8, the transport device withdraws the Z-axis moving mechanism 6 and the material-taking mechanism 7 from the heating unit. The driving mechanism 1 is then rotated to return the Z-axis moving mechanism 6 and the material-taking mechanism 7 to the origin through the fixed seat 3. The structure is simple and easy to use. The stability when transferring the pizza box 8 is further enhanced, and there will be no shaking when transferring the pizza box 8.

[0048] In a further specific embodiment, a limiting component 4 is provided between the fixing seat 3 and the mounting seat 2, wherein a first end of the limiting component 4 is connected to the fixing seat 3, and a second end of the limiting component 4 is connected to the mounting seat 2.

When the rotating mechanism rotates to a specified angle, the limiting member 41 abuts against the limiting plate 42. The rotation angle of the fixing seat 3 is limited by the cooperation of the limiting plate 42 and the limiting member 41 to avoid excessive rotation angle, which causes the pizza box 8 to be stuck outside the heating unit when the pizza box 8 is transferred. The structure is simple and the rotation accuracy of the rotating mechanism is enhanced.

By setting the limiting groove 421, when the rotating mechanism drives the fixed seat 3 to rotate, the limiting member 41 always moves in the limiting groove 421, further enhancing the stability of the rotation and avoiding excessive rotation angle. It should be noted that the rotation path formed by the limiting groove 421 in this embodiment makes the rotation angle of the rotating mechanism 90°. The limiting groove 421 of this embodiment is arc-shaped, so when the rotating mechanism drives the fixed seat 3 to rotate, the limiting member 41 can move smoothly in the arc-shaped limiting groove 421. In other specific embodiments, the rotation angle of the rotating mechanism can also be limited to other angles according to actual needs.

[0051] The limit assembly 4 also includes a limit switch 43 and a switch paddle 44; the limit switch 43 is installed on the mounting seat 2, and the switch paddle 44 is installed on the fixed seat 3; when the rotating mechanism rotates to a specified angle, the switch paddle 44 touches the limit switch 43. The setting of the limit switch 43 and the switch paddle 44 limits the angle at which the rotating mechanism drives the fixed seat 3 to rotate, and when the switch paddle 44 touches the limit switch 43, the rotating mechanism stops rotating. The rotation angle of the rotating mechanism is limited by the combination of the limit switch 43 and the switch paddle 44, and the limit member 41 and the limit plate 42. It should be noted that the number of limit paddles of the limit switch 43 of this embodiment is two groups, one group of limit switches 43 and limit paddles limits the first end of the limit slot 421, and the other group of limit switches 43 and limit paddles limits the second end of the limit slot 421.

By setting the mounting groove 211, the limit switch 43 is installed in the mounting groove 211, the space between the mounting seat 2 and the fixing seat 3 is reduced, the structure is simple, and the practicability is strong.

[0053] In a further specific embodiment, a connecting member 5 is further included, wherein the first end of the connecting member 5 is connected to the fixed seat 3, the second end of the connecting member 5 is connected to the driving mechanism 1, and the limit plate 42 and the mounting seat 2 are respectively installed in the middle of the connecting member 5. The driving mechanism 1 drives the fixed seat 3 to rotate through the connecting member 5. It should be noted that the connecting member 5 penetrates the limit plate 42 and the mounting seat 2. The connecting member 5 includes a connecting seat 51, a first bearing 52 and a second bearing 53, the inner rings of the first bearing 52 and the second bearing 53 are respectively sleeved on the connecting seat 51, the first end of the connecting seat 51 is connected to the fixed seat 3, the second end of the connecting seat 51 is connected to the output end of the driving mechanism 1, the outer ring of the first bearing 52 is connected to the limit plate 42, and the outer ring of the second bearing 53 is connected to the mounting seat 2.
