[0036] Embodiment

[0037] As shown in Figures 1-6 The pizza box carrying device comprises an X-axis moving mechanism, a Y-axis moving mechanism, a rotating mechanism 1, a Z-axis moving mechanism 2 and a material taking mechanism 3 for clamping a pizza box 4, which are mounted on a main cabinet of a pizza machine. The Y-axis moving mechanism is mounted on the moving end of the X-axis moving mechanism. The rotating mechanism 1 is mounted on the moving end of the Y-axis moving mechanism. The Z-axis moving mechanism 2 is mounted on the rotating end of the rotating mechanism 1. The material taking mechanism 3 is mounted on the moving end of the Z-axis moving mechanism 2. The material taking mechanism 3 comprises a material supporting assembly 31, which is slidingly mounted on the Z-axis moving mechanism 2 and is used for supporting and limiting the pizza box 4; a limiting piece 32, which is slidingly mounted on the material supporting assembly 31 and cooperates with the material supporting assembly 31 to limit the pizza box 4; and an elastic assembly 33, one end of which abuts against the limiting piece 32 and the other end of which is mounted on the material supporting assembly 31 or the Z-axis moving mechanism 2, and is used for moving the limiting piece 32 towards the pizza box 4.

[0038] When the pizza box 4 is carried, the pizza box 4 is supported and moved by the material supporting assembly 31, and the limiting piece 32 is moved towards the pizza box 4 by the elastic assembly 33. The pizza box 4 is clamped and limited by the material supporting assembly 31 and the limiting piece 32. The structure is simple, no additional driving motor is needed, and the clamping of the pizza box 4 can be completed by the Z-axis moving mechanism 2, thereby reducing the production cost.

[0039] In a further specific embodiment, the material supporting assembly 31 comprises a bracket 311 and a material supporting piece 312, the bracket 311 is slidingly installed on the Z-axis moving mechanism 2, the limiting piece 32 is slidingly installed on the top of the bracket 311, and the material supporting piece 312 is installed on the bracket 311. The transmission power is transferred through the bracket 311, so that the limiting piece 32 and the material supporting piece 312 can be moved on the Z-axis moving mechanism 2 under the driving of the bracket 311. It should be noted that the Z-axis moving mechanism 2 in this embodiment is provided with a motor, a synchronous belt and a synchronous wheel set, and the bottom of the bracket 311 is connected with the synchronous belt. It can be understood that in other specific embodiments, the Z-axis moving mechanism 2 can also be provided with a combination transmission mode of a motor, a gear and a rack, or a combination transmission mode of a motor, a screw rod and a nut seat. Since the Z-axis moving mechanism 2 is prior art, it will not be described again.

[0040] In a further specific embodiment, the first end of the material supporting piece 312 is installed on the bracket 311, the second end of the material supporting piece 312 is provided with a clamping hook 313, and the clamping hook 313 is used to hook the pizza box 4 from the bottom of the pizza box 4. Through the setting of the clamping hook 313, the clamping hook 313 can limit the position of the pizza box 4 when the material supporting piece 312 lifts the pizza box 4. It should be noted that the pizza box 4 in the prior art is provided with a plurality of box opening holes at the bottom, so that the pizza box 4 cover and the pizza top can be lifted by the driving mechanism of the box opening device and the box opening frame. Therefore, the clamping hook 313 of this embodiment can directly extend into the box opening hole at the bottom of the pizza box 4 to hook the pizza box 4, or a limiting hole corresponding to the material supporting piece 312 can be opened at the bottom of the pizza box 4 according to actual needs, and the clamping hook 313 extends into the limiting hole to hook the pizza box 4. In other specific embodiments, the limiting piece 32 limits one side of the pizza box 4, and the material supporting piece 312 can directly extend to the other side of the pizza box 4 to limit the other side of the pizza box 4 through the clamping hook 313. Under the cooperation of the material supporting piece 312 and the limiting piece 32, the two sides of the pizza box 4 are clamped and limited respectively.

[0041] As shown in Figure 6 In a further specific embodiment, the clamping hook 313 comprises a mounting portion 3131 and a clamping portion 3132, the clamping portion 3132 is arranged on the top of the mounting portion 3131, and the cross section of the clamping portion 3132 is triangular or trapezoidal.

[0042] The snap-fit ​​part 3132 enables the hook 313 to limit the pizza box 4. It should be noted that when the material carrier 312 enters the storage device of the self-service pizza machine to pick up the pizza box 4, the top of the snap-fit ​​part 3132 is lower than the bottom of the pizza box 4. When the Z-axis moving mechanism 2 moves the material carrier 312 to the set position, the Y-axis moving mechanism drives the material picking mechanism 3 to rise a set distance through the rotating mechanism 1 and the Z-axis moving mechanism 2, so that the top of the mounting part 3131 fits against the bottom of the pizza box 4. The snap-fit ​​part 3132 extends into the limiting hole or opening hole at the bottom of the pizza box 4. With the cooperation of the limiting part 32, it clamps and limits both sides of the pizza box 4.

[0043] It is understood that in other specific embodiments, before the material carrier 312 enters the storage device of the self-service pizza machine to pick up the pizza box 4, the top position of the mounting part 3131 is lower than or equal to the bottom position of the pizza box 4. When the Z-axis moving mechanism 2 drives the material carrier 312 to move to the set position, the locking part 3132 first lifts up the pizza box 4. After the locking part 3132 enters the limiting hole or opening hole at the bottom of the pizza box 4, the pizza box 4 falls down, and the top of the mounting part 3131 fits against the bottom of the pizza box 4. With the cooperation of the limiting part 32, the material carrier 312 clamps and limits the two sides of the pizza box 4 respectively.

[0044] It should be noted that in other specific embodiments, before the tray 312 enters the storage device of the self-service pizza machine to pick up the pizza box 4, the top of the mounting part 3131 is lower than or equal to the bottom of the pizza box 4. When the Z-axis moving mechanism 2 moves the tray 312 to the set position, the locking part 3132 first lifts the pizza box 4. When the locking part 3132 passes directly through the pizza box 4 and is located on the other side of the pizza box 4, the pizza box 4 falls down, and the top of the mounting part 3131 fits against the bottom of the pizza box 4. The tray 312, in cooperation with the limiting part 32, clamps and limits both sides of the pizza box 4. In this embodiment, the bottom of the pizza box 4 may not have a limiting hole and / or an opening hole.

[0045] like Figures 3-5 As shown in a further specific embodiment, the first end of the limiting member 32 is installed on the material support assembly 31, and the second end of the limiting member 32 is installed with a limit switch 34. The limit switch 34 is electrically connected to the Z-axis moving mechanism 2. When the sensing end of the limit switch 34 touches the pizza box 4 to close, the limiting member 32 touches the pizza box 4.

[0046] The movement position of the material taking mechanism 3 is limited by the setting of the limit switch 34. When the limit switch 34 is closed, the Z-axis moving mechanism 2 stops the movement of the material taking mechanism 3 to the pizza box 4. It should be noted that although the limit switch 34 can limit the movement position of the material taking mechanism 3, the limitation is only for the movement of the material taking mechanism 3 to the storage device of the self-service pizza machine. When the material taking mechanism 3 drives the pizza box 4 to the box opening device, the limit switch 34 no longer limits the movement position of the material taking mechanism 3.

[0047] In further embodiments, the limit switch 34 is a spring switch. The trigger tab 341 of the spring switch is exposed to the limiting piece 32. The force of the trigger tab 341 moving to touch the trigger point of the spring switch is greater than the force required for the limiting piece 32 to slide on the material supporting assembly 31. The material supporting assembly 31 is provided with a limiting block 353 for limiting the movement of the limiting piece 32 on the material supporting assembly 31.

[0048] It should be noted that since the trigger tab 341 contacts the pizza box 4 earlier than the limiting piece 32, the limiting piece 32 is driven by the trigger tab 341 to move backward under force until the limiting piece 32 abuts against the limiting block 353. At this time, the limiting piece 32 loses the movement space, and the pizza box 4 gradually approaches the limiting piece 32. When the limiting piece 32 touches the pizza box 4, the trigger tab 341 also moves to touch the trigger point of the spring switch, so that the Z-axis moving mechanism 2 stops pushing the material taking mechanism 3, and the clamping of the pizza box 4 is completed.

[0049] As shown in Figures 3-5 In further embodiments, a guide assembly 35 is arranged between the material supporting assembly 31 and the limiting piece 32. The guide assembly 35 includes a guide rail 351 and a sliding block 352. The guide rail 351 is installed on the top of the material supporting assembly 31, and the sliding block 352 is installed on the bottom of the limiting piece 32. The limiting piece 32 is slidably installed on the guide rail 351 through the sliding block 352. The guide assembly 35 enables the limiting piece 32 to move relative to the material supporting assembly 31, so as to realize the clamping of the pizza box 4 by the limiting piece 32 and the material supporting assembly 31.

[0050] As shown in Figures 3-5 In further embodiments, the guide assembly 35 further includes a limiting block 353 installed on the first end of the guide rail 351. The top of the material supporting assembly 31 is provided with a stop block 36 arranged at the second end of the guide rail 351. The limiting block 353 and the stop block 36 respectively limit the position of the guide assembly 35, which is simple in structure and strong in practicability.

[0051] In a further specific embodiment, the elastic assembly 33 comprises an elastic member 331 and a mounting base 332, the mounting base 332 is mounted on the Z-axis moving mechanism 2, and the first end of the elastic member 331 is mounted on the limiting member 32, and the second end of the elastic member 331 abuts against the mounting base 332 when the material taking mechanism 3 is retracted to the initial position on the Z-axis moving mechanism 2.

[0052] It should be noted that the elastic member 331 of the embodiment is a spring, and the distance between the mounting base 332 and the limiting member 32 gradually decreases when the material taking mechanism 3 is retracted to the initial position on the Z-axis moving mechanism 2, and the elastic member 331 pushes the limiting member 32 to move towards the pizza box 4, and the limiting member 32 is slidingly mounted on the material supporting assembly 31, so that the elastic member 331 pushes the limiting member 32 to move towards the pizza box 4, and the material supporting assembly 31 completes the clamping of the pizza box 4.

[0053] As shown in Figures 3-5 In a further specific embodiment, the elastic assembly 33 further comprises a guide shaft 333, the first end of the guide shaft 333 is mounted on the limiting member 32, the elastic member 331 is sleeved on the guide shaft 333, and the mounting base 332 is provided with a guide hole 3321, and the second end of the guide shaft 333 penetrates through the guide hole 3321 when the material taking mechanism 3 is retracted to the initial position on the Z-axis moving mechanism 2.

[0054] The setting can keep the elastic member 331 within a certain range when it is retracted, that is, within the guide shaft 333, so as to avoid the elastic member 331 from being forced to pop out to one side when it is retracted, and to make the elastic member 331 uniformly retract. When the material taking mechanism 3 is retracted to the initial position on the Z-axis moving mechanism 2, the second end of the guide shaft 333 penetrates through the guide hole 3321 and enters the mounting base 332, and the second end of the elastic member 331 abuts against the mounting base 332. It can be understood that the diameter of the elastic member 331 is greater than the diameter of the guide hole 3321, so as to avoid the elastic member 331 from entering the mounting base 332 and causing the pushing force of the elastic member 331 on the limiting member 32 to decrease.

[0055] The description of “specific example”, or “some examples” or the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the utility model.
