[0036] Example

[0037] like Figure 1-6 As shown, the pizza box handling device includes an X-axis moving mechanism, a Y-axis moving mechanism, a rotating mechanism 1, a Z-axis moving mechanism 2 and a material picking mechanism 3 for clamping a pizza box 4, which are installed on the main cabinet of the pizza machine; the Y-axis moving mechanism is installed on the moving end of the X-axis moving mechanism; the rotating mechanism 1 is installed on the moving end of the Y-axis moving mechanism; the Z-axis moving mechanism 2 is installed on the rotating end of the rotating mechanism 1; the material picking mechanism 3 is installed on the moving end of the Z-axis moving mechanism 2, and the material picking mechanism 3 includes: a material supporting component 31, which is slidably installed on the Z-axis moving mechanism 2, and is used to hold up the pizza box 4 and limit the pizza box 4; a limiting member 32, which is slidably installed on the material supporting component 31, and cooperates with the material supporting component 31 to limit the pizza box 4; an elastic component 33, one end of which is against the limiting member 32, and the other end is installed on the material supporting component 31 or the Z-axis moving mechanism 2, and is used to push the limiting member 32 to move toward the pizza box 4.

[0038] When the pizza box 4 is transported, the pizza box 4 is lifted and moved by the setting of the supporting component 31, and the limiting component 32 is moved toward the pizza box 4 by the setting of the elastic component 33. With the cooperation of the supporting component 31 and the limiting component 32, the pizza box 4 is clamped and limited. The structure is simple, and no additional driving motor is required. The pizza box 4 can be clamped only by providing power through the Z-axis moving mechanism 2, thereby reducing production costs.

[0039] In a further specific embodiment, the support assembly 31 includes a bracket 311 and a support member 312, the bracket 311 is slidably mounted on the Z-axis moving mechanism 2, the limiter 32 is slidably mounted on the top of the bracket 311, and the support member 312 is mounted on the bracket 311. The power of the transmission is transferred by the setting of the bracket 311, so that the limiter 32 and the support member 312 can move on the Z-axis moving mechanism 2 driven by the bracket 311. It should be noted that the Z-axis moving mechanism 2 of this embodiment uses the setting of a motor, a synchronous belt and a synchronous wheel set, and the bottom of the bracket 311 is connected to the synchronous belt. It can be understood that in other specific embodiments, the Z-axis moving mechanism 2 can also use a combined transmission mode of a motor, a gear, and a rack, or a combined transmission mode of a motor, a screw rod and a nut seat. Since the Z-axis moving mechanism 2 is a prior art, it will not be repeated.

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

[0041] like Figure 6 As shown, in a further specific embodiment, the hook 313 includes a mounting portion 3131 and a clamping portion 3132 , the clamping portion 3132 is disposed on the top of the mounting portion 3131 , and the cross-section of the clamping portion 3132 is a triangle or a trapezoid.

[0042] The hook 313 is capable of limiting the position of the pizza box 4 through the setting of the clamping portion 3132. It should be noted that when the material supporting member 312 enters the storage device of the self-service pizza machine to pick up the pizza box 4, the position of the top of the clamping portion 3132 is lower than the bottom of the pizza box 4. When the Z-axis moving mechanism 2 drives the material supporting member 312 to move 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 portion 3131 fits with the bottom of the pizza box 4, and the clamping portion 3132 extends into the limiting hole or the box opening hole at the bottom of the pizza box 4, and in cooperation with the limiting member 32, the two sides of the pizza box 4 are clamped and limited respectively.

[0043] It can be understood that in other specific embodiments, before the supporting member 312 enters the storage device of the self-service pizza machine to pick up the pizza box 4, the position of the top of the mounting portion 3131 is lower than or equal to the position of the bottom of the pizza box 4, and when the Z-axis moving mechanism 2 drives the supporting member 312 to move to the set position, the clamping portion 3132 first lifts the pizza box 4, and after the clamping portion 3132 enters the limiting hole or the box opening hole at the bottom of the pizza box 4, the pizza box 4 falls, and the top of the mounting portion 3131 fits against the bottom of the pizza box 4, and the supporting member 312, in cooperation with the limiting member 32, clamps and limits the two sides of the pizza box 4 respectively.

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

[0045] like Figure 3-Figure 5 As shown, in a further specific embodiment, the first end of the limit member 32 is installed on the material supporting assembly 31, and the second end of the limit member 32 is installed with a limit switch 34, and 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 limit member 32 touches the pizza box 4.

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

[0047] In a further specific embodiment, the limit switch 34 is a spring switch, and the trigger paddle 341 of the spring switch is exposed from the limit member 32. The force of the trigger paddle 341 moving to touch the trigger point of the spring switch is greater than the force required for the limit member 32 to slide on the support assembly 31. A limit block 353 is provided on the support assembly 31, and the limit block 353 is used to limit the movement of the limit member 32 on the support assembly 31.

[0048] It should be noted that, since the trigger paddle 341 contacts the pizza box 4 before the limiter 32, the limiter 32 is driven by the trigger paddle 341 to move backwards under the force until the limiter 32 hits the limiter block 353. At this time, the limiter 32 loses the moving space, and the pizza box 4 gradually approaches the limiter 32. When the limiter 32 touches the pizza box 4, the trigger paddle 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 pizza box 4 is clamped.

[0049] like Figure 3-Figure 5 As shown, in a further specific embodiment, a guide assembly 35 is provided between the support assembly 31 and the limiting member 32, and the guide assembly 35 includes a guide rail 351 and a slider 352. The guide rail 351 is installed at the top of the support assembly 31, and the slider 352 is installed at the bottom of the limiting member 32. The limiting member 32 is slidably installed on the guide rail 351 through the slider 352. The setting of the guide assembly 35 enables the limiting member 32 to move relative to the support assembly 31, so that the limiting member 32 cooperates with the support assembly 31 to clamp the pizza box 4.

[0050] like Figure 3-Figure 5 As shown, in a further specific embodiment, the guide assembly 35 further includes a limit block 353, the limit block 353 is installed at the first end of the guide rail 351, and a stop block 36 is installed on the top of the support assembly 31, and the stop block 36 is arranged at the second end of the guide rail 351. The position of the guide assembly 35 is limited by the setting of the limit block 353 and the stop block 36, which has a simple structure and strong practicality.

[0051] In a further specific embodiment, the elastic component 33 includes an elastic member 331 and a mounting seat 332, the mounting seat 332 is installed on the Z-axis moving mechanism 2, the first end of the elastic member 331 is installed on the limiting member 32, and when the material picking mechanism 3 retracts to the initial position on the Z-axis moving mechanism 2, the second end of the elastic member 331 abuts against the mounting seat 332.

[0052] It should be noted that the elastic member 331 of this embodiment is a spring. Through this arrangement, when the material picking mechanism 3 retracts to the initial position on the Z-axis moving mechanism 2, the distance between the mounting seat 332 and the limiting member 32 gradually decreases. Since the position of the mounting seat 332 is fixed, and the limiting member 32 is slidably installed on the supporting assembly 31, the elastic member 331 will push the limiting member 32 to move in the direction of the pizza box 4, and complete the clamping of the pizza box 4 in cooperation with the supporting assembly 31.

[0053] like Figure 3-Figure 5 As shown, in a further specific embodiment, the elastic component 33 also includes a guide shaft 333, the first end of the guide shaft 333 is installed on the limiting member 32, the elastic member 331 is sleeved on the guide shaft 333, and the mounting seat 332 is provided with a guide hole 3321. When the material picking mechanism 3 retracts to the initial position on the Z-axis moving mechanism 2, the second end of the guide shaft 333 passes through the guide hole 3321.

[0054] This arrangement enables the elastic member 331 to always remain within a certain range when contracting, that is, to remain within the guide shaft 333, so as to prevent the elastic member 331 from being forced to pop out to one side when contracting, and to make the elastic member 331 contract evenly. When the material picking mechanism 3 retracts to the initial position on the Z-axis moving mechanism 2, the second end of the guide shaft 333 will pass through the guide hole 3321 and enter the mounting seat 332, and the second end of the elastic member 331 will abut against the mounting seat 332. It can be understood that the diameter of the elastic member 331 is larger than the diameter of the guide hole 3321, so as to prevent the elastic member 331 from entering the mounting seat 332, resulting in a smaller thrust of the elastic member 331 on the limit member 32.

[0055] Descriptions such as "specific examples" or "some examples" mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments or examples described in this specification and features of different embodiments or examples, unless they are contradictory.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments.
