Description

Technical Field

[0001] This invention relates to the field of catering equipment technology, and in particular to a transfer device for a dumpling machine. Background Technology

[0002] A dumpling machine is an automated dumpling cooking device, typically equipped with a refrigerator, a steamer, and a pickup cabinet. Through internal mechanisms, dumplings are placed from the refrigerator into the steamer, cooked, and then packaged in boxes before being placed in the pickup cabinet for customers to collect. This automated dumpling cooking and sales system, allowing for unattended operation, has broad market prospects.

[0003] Currently, dumpling machines typically use robotic arms to transfer dumplings. However, the robotic arms in existing dumpling machines require flipping motions and the cooperation of other mechanisms to achieve smooth transfer, resulting in redundant and complex robotic arm movements, numerous control programs, and a serious impact on the transfer efficiency of dumplings in the dumpling machine.

[0004] Therefore, given the current situation where the robotic arms in existing dumpling machines have excessive and complex movements and numerous control programs, which seriously affect the efficiency of dumpling transfer, it is an urgent problem to develop a fast and efficient transfer device for dumpling machines. Summary of the Invention

[0005] The purpose of this invention is to address the problem that the robotic arms in existing dumpling machines have excessive and complex movements and numerous control programs, which seriously affect the efficiency of dumpling transfer. The invention proposes and designs a fast and efficient transfer device for dumpling machines.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a transfer device for a dumpling machine, including a left-right translation mechanism, a lifting mechanism slidably connected to the left-right translation mechanism, a support frame slidably connected to the lifting mechanism, a gripper assembly installed on the support frame, a gripper opening and closing drive and a gripper forward and backward translation drive connected to the gripper assembly, the gripper opening and closing drive can drive the gripper assembly to open and close, and the gripper forward and backward translation drive can drive the gripper assembly to move forward and backward, a placement plate is provided on the support frame, a through hole is provided on the placement plate, a material box fixing fork assembly is provided below the placement plate, a dumpling conveying device is provided above the support frame, a dumpling conveying material box is installed on the dumpling conveying device, the dumpling conveying material box has a split structure, a limiting structure is provided at the bottom of the dumpling conveying material box, the dumpling conveying device can place the dumpling conveying material box on the placement plate, and the limiting structure can pass through the through hole on the placement plate and be engaged by the material box fixing fork assembly, and a fork assembly is also provided on the support frame. Because the dumpling conveyor box has a split structure, the lower part of the box is held in place by the box fixing fork assembly, while the upper part is gripped and moved forward by the gripper assembly. This misalignment between the upper and lower parts of the box allows the dumplings to enter the steaming pot, thus completing the dumpling feeding action. The gripper assembly can move back and forth and open and close, enabling the forward and backward movement and clamping of the packaging box and conveyor box. The left-right translation mechanism and lifting mechanism allow the support frame to move left and right and up and down, meeting the needs of different positional movements. The fork assembly is used to rotate the steaming pot, causing it to pour the dumplings into the packaging box. The operation is simple, requiring only three-dimensional translation, eliminating the need for the robotic arm's flipping action. The transfer of the packaging box is completed by the robotic arm itself, with no unnecessary movements, reducing the program control of other devices in the dumpling machine and significantly improving efficiency.

[0007] Furthermore, the fork assembly includes a fork head and a fork front and rear drive component. The fork head is connected to the fork front and rear drive component, which drives the fork head to move horizontally back and forth. The fork front and rear drive component is preferably a cylinder. Its function during use is to drive the fork head forward, causing it to extend and insert into the socket of the matching steamer. Driven by a lifting mechanism, the fork head moves downward, pulling the steamer to rotate at a certain angle, thus pouring the dumplings into the packaging box on the robotic arm. This makes the transfer of dumplings from the steamer to the packaging box simpler and more efficient.

[0008] Furthermore, the hopper fixing fork assembly includes a fixing fork and a fixing fork drive, wherein the fixing fork is connected to the fixing fork drive.

[0009] Furthermore, the limiting structure includes a limiting post, and a locking protrusion is provided on the side wall of the limiting post. The fixed fork driving component can drive the fixed fork to move so that the fixed fork is engaged with the limiting post. By providing the locking protrusion, an engagement space for the fixed fork is formed between the locking protrusion and the limiting post, thereby enabling the fixed fork to reliably engage with the limiting structure.

[0010] Furthermore, the gripper assembly includes two grippers, each with a clamping groove on its inner side. The grippers are located above the placement plate, and their rear ends are connected to a gripper opening and closing drive component. The gripper opening and closing drive component is preferably a cylinder. Each gripper is driven by a cylinder to achieve the opening and closing action, and the clamping groove can be engaged with a packaging box or material box for positioning.

[0011] Furthermore, the gripper's forward and backward translational drive includes a gripper frame and a lead screw. The lead screw is mounted on a support frame, and the gripper frame is connected to the lead screw via a nut. The gripper and the gripper opening and closing drive are both mounted on the gripper frame, which is connected to the support frame via a slider guide rail structure. This achieves the drive for the gripper's forward and backward movement without affecting its opening and closing action during forward and backward movement.

[0012] Furthermore, the claw frame is equipped with a horizontal positioning plate, which is located above the placement plate. The horizontal positioning plate has positioning holes, and the dumpling conveyor box is equipped with a positioning plug. When the dumpling conveyor box descends, its positioning plug is inserted into the positioning hole to achieve coarse positioning, so as to facilitate the accurate descent of the dumpling conveyor box onto the placement plate.

[0013] Furthermore, the dumpling conveyor box includes a box body and a base plate. The box body has a through-type structure, meaning both the upper and lower parts of the box body are open. The box body is slidably connected to the base plate, and the limiting structure is disposed on the base plate. Side baffles are provided on both sides of the base plate, and the side baffles are connected to the box body via guide rail sliders, realizing stable sliding movement of the box body and providing obstruction on both sides of the base plate.

[0014] Furthermore, both the left-right translation mechanism and the lifting mechanism adopt a ball screw drive structure. The dumpling conveying device is also preferably a ball screw drive structure, with grippers installed on it for clamping the dumpling conveying box.

[0015] As can be seen from the above technical solutions, the present invention has the following advantages:

[0016] This solution provides a transfer device for a dumpling machine. Because the dumpling conveyor box has a split structure, the lower part is held in place by a fork assembly, while the upper part is gripped and moved forward by a claw assembly. This misalignment between the upper and lower parts of the conveyor box allows the dumplings to enter the steaming pot, thus completing the dumpling feeding action. The claw assembly can move back and forth and open and close, enabling the forward and backward movement and clamping of the packaging box and conveyor box. A left-right translation mechanism and a lifting mechanism allow the support frame to move left and right and up and down, meeting the needs of different positional movements. A fork assembly is used to rotate the steaming pot, pouring the dumplings into the packaging box. The operation is simple, requiring only three-dimensional translation, eliminating the need for flipping. The transfer of the packaging box is completed by the robotic arm without any unnecessary movements, reducing the program control of other devices in the dumpling machine and significantly improving efficiency.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figures 1 to 4 As shown in the figure, this specific embodiment provides a transfer device for a dumpling machine, including a left-right translation mechanism 1, a lifting mechanism 2 slidably connected to the left-right translation mechanism, a support frame 5 slidably connected to the lifting mechanism 2, a gripper 10 assembly mounted on the support frame 5, a gripper opening and closing drive 9 and a gripper forward and backward translation drive 10 connected to the gripper 10 assembly, the gripper opening and closing drive 9 can drive the gripper 10 assembly to open and close, and the gripper forward and backward translation drive 10 can drive the gripper 10 assembly to move forward and backward, and a placement plate 6 is provided on the support frame 5. The placement plate 6 is provided with a through hole 12. The material box fixing fork 16 assembly is provided below the placement plate 6. The dumpling conveying device 3 is provided above the support frame 5. The dumpling conveying device 3 is equipped with a dumpling conveying material box 4. The dumpling conveying material box 4 has a split structure. The bottom of the dumpling conveying material box 4 is provided with a limiting structure 18. The dumpling conveying device 3 can place the dumpling conveying material box 4 on the placement plate 6. The limiting structure 18 can pass through the through hole 12 on the placement plate 6 and be engaged by the material box fixing fork 16 assembly. The support frame 5 is also provided with a shift fork assembly.

[0025] The fork assembly includes a fork head 15 and a fork front-to-back drive member 14. The fork head 15 is connected to the fork front-to-back drive member 14, which drives the fork head 15 to move horizontally back and forth. The fork front-to-back drive member 14 is preferably a cylinder. Its function during use is to drive the fork head 15 forward, causing it to extend and insert into the corresponding socket of the steaming pot. Driven by the lifting mechanism 2, it moves downward, pulling the steaming pot to rotate at a certain angle, pouring the dumplings into the packaging box on the robotic arm. This makes the transfer of dumplings from the steaming pot to the packaging box simpler and more efficient. The material box fixing fork 16 assembly includes a fixing fork 16 and a fixing fork drive member 17. The fixing fork 16 is connected to the fixing fork drive member 17. The limiting structure 18 includes a limiting post with a locking protrusion on its side wall. The fixed fork drive member 17 can drive the fixed fork 16 to move so that the fixed fork 16 can engage with the limiting post. By setting the locking protrusion, an engagement space for the fixed fork 16 is formed between the locking protrusion and the limiting post, thereby reliably engaging the fixed fork 16 with the limiting structure 18. Specifically, the gripper 10 assembly includes two grippers 10, each with a clamping groove on its inner side. The grippers 10 are located above the placement plate 6, and the rear of the grippers 10 is connected to the gripper opening and closing drive member 9. The gripper opening and closing drive member 9 is preferably a cylinder, and each gripper 10 is driven by a cylinder to realize the opening and closing action. The clamping groove can engage with the packaging box or material box for limiting. The gripper 10 forward and backward translation drive includes a gripper frame 7 and a lead screw 13. The lead screw 13 is mounted on the support frame 5. The gripper frame 7 is connected to the lead screw 13 via a nut. The gripper 10 and the gripper opening and closing drive 9 are both mounted on the gripper frame 7. The gripper frame 7 is connected to the support frame 5 via a slider guide rail structure, realizing the drive for the forward and backward movement of the gripper without affecting the opening and closing action of the gripper during the forward and backward movement. A horizontal positioning plate 8 is provided on the gripper frame, which is located above the placement plate 6. The horizontal positioning plate 8 is provided with a positioning hole 11. The dumpling conveying box 4 is provided with a positioning plug. When the dumpling conveying box 4 descends, its positioning plug is inserted into the positioning hole 11 to achieve coarse positioning, so as to facilitate the accurate descent of the dumpling conveying box 4 onto the placement plate 6.

[0026] In addition, the dumpling conveying box 4 includes a box body 401 and a bottom plate 402. The box body 401 has a through structure, that is, both the upper and lower parts of the box body 401 are open. The box body 401 is slidably connected to the bottom plate 402. The limiting structure 18 is set on the bottom plate 402. Side baffles 403 are set on both sides of the bottom plate 402. The side baffles 403 are connected to the box body 401 through a guide rail slider, so as to realize the stable sliding movement of the box body 401 and the blocking on both sides of the bottom plate 402.

[0027] It should be noted that in this solution, the left and right translation mechanism and the lifting mechanism 2 both adopt a ball screw drive structure, and the dumpling conveying device 3 is also preferably a ball screw drive structure, on which a clamping claw for clamping the dumpling conveying box 4 is installed.

[0028] Its working principle is as follows: During use, raw dumplings are placed in the dumpling conveying box 4. The dumpling conveying device 3 transports the dumpling conveying box 4 to a position above the placement plate 6, then lowers it. The limiting structure 18 on the bottom plate 402 passes through the through hole 12 of the placement plate 6. The fixed fork drive member 17 drives the fixed fork 16 to move, causing the fixed fork 16 to engage with the limiting structure 18 to fix the position of the bottom plate 402. The gripper 10 clamps the box body 401. Driven by the forward and backward translation drive member of the gripper 10, the gripper 10 moves the box body 401 forward, causing the box body 401 to slowly shift away from the bottom plate 402. The box body 401 pushes the dumplings forward. After the raw dumplings pass through the shifted box body 401... The dumpling falls through the gap between the bottom plate 402 and the bottom plate 402 and enters the dumpling pot. Driven by the left and right translation mechanism and the lifting mechanism 2, it moves to the packaging box position. The gripper opening and closing drive 9 drives the gripper 10 to open. The gripper 10 forward and backward translation drive drives the gripper 10 to move forward, holding the packaging box and moving it to the placement plate 6. Then it moves to the steaming pot position. The fork forward and backward drive 14 drives the fork head 15 to move forward, so that the fork head 15 protrudes and inserts into the socket of the steaming pot. Driven by the lifting mechanism 2, it moves downward, thereby pulling the steaming pot to flip it at a certain angle and pouring the dumplings into the packaging box on the robotic arm. The whole process is simpler and more efficient.
