[0034] Example 1

[0035] This embodiment is applicable to transferring rice balls from a first position to a second position. The rice balls referred to here include both rice balls without any added ingredients and rice balls with added ingredients such as ham sausage.

[0036] Please see Figure 1 This embodiment provides a rice ball transfer device, which includes a frame 100, a translation mechanism 200, a lifting mechanism 300, and a clamping mechanism 400.

[0037] The rack 100 is configured as a tabletop structure, and the rack 100 is provided with a tray 110. The tray 110 is used to hold and transfer rice balls to this embodiment, that is, the tray 110 is the second position mentioned above. In this embodiment, the bearing surface of the tray 110 can be set to be horizontal. When the tray 110 is full, the rice balls are arranged in an array on the bearing surface.

[0038] The array pattern of the rice balls can be set according to the controller. For example, there is a preset gap between adjacent rice balls in each row and between rice balls in adjacent rows, which can prevent the rice balls from being damaged or deformed.

[0039] The translation mechanism 200 is mounted on the frame 100. The translation mechanism 200 has a translation end 210. The translation end 210 moves relative to the frame 100 in a first direction, and the tray 110 is located within the translation range of the translation end 210.

[0040] In this embodiment, the translation mechanism 200 is configured as an X-axis linear module, with the first direction being the axial direction of the X-axis, i.e., the horizontal direction. The translation mechanism 200 moves left and right relative to the frame 100 in the horizontal direction, and the bearing surface of the tray 110 is located within the translation range of the translation end 210.

[0041] In some embodiments, the translation mechanism 200 is further configured as an X-axis linear module and a Y-axis linear module, and the translation end 210 is coupled to move under the control of the controller, so that multiple rows of rice balls can be placed in the tray 110, saving time for changing the tray 110.

[0042] The lifting mechanism 300 is installed on the translation end 210. The lifting mechanism 300 has a lifting end 341, which moves relative to the translation end 210 in the second direction.

[0043] In this embodiment, the second direction can be set as the axis direction of the Z-axis, that is, the vertical direction, and the lifting end 341 moves up and down relative to the translation end 210 in the vertical direction.

[0044] Please see Figure 2 and Figure 3 The lifting mechanism 300 includes a mounting frame 310, a second driving member 320, a transmission assembly 330, and a machine head 340. The mounting frame 310 is fixedly connected to the translation end 210. The second driving member 320 is mounted on the mounting frame 310. The input end of the transmission assembly 330 is connected to the driving end of the second driving member 320. The output end of the transmission assembly 330 is rotatably connected to the machine head 340. The machine head 340 is provided with a lifting end 341.

[0045] The second drive unit 320 is configured as a motor, and the transmission assembly 330 includes a first gear 331, a second gear 332, a rocker arm 333, and a lifting arm 334. The first gear 331 is connected to the drive end of the second drive unit 320. The second gear 332 meshes with the first gear 331, and the number of teeth of the second gear 332 is greater than the number of teeth of the first gear 331. The rocker arm 333 is fixedly connected to the second gear 332 through the second shaft b. One end of the lifting arm 334 is rotatably connected to the rocker arm 333 around the third shaft c, and the other end of the lifting arm 334 is rotatably connected to the machine head 340 around the fourth shaft d.

[0046] The motor drives the first gear 331 to rotate, which in turn drives the second gear 332 to rotate, thereby reducing the rotational speed. The second gear 332 then drives the rocker arm 333 to rotate around the second shaft b. The rocker arm 333 drives the lifting arm 334 to move up and down, converting the rotational output into linear motion. Finally, the lifting arm 334 drives the machine head 340 to move up and down, thus realizing the lifting function of the lifting mechanism 300.

[0047] Please see Figure 3 and Figure 4The clamping mechanism 400 is installed on the lifting end 341, and the clamping mechanism 400 has two states: open and closed.

[0048] In this embodiment, the clamping mechanism 400 can be configured to include a first driving member 410, a grooved wheel assembly 420, a lifting rod 430, and two opposing clamping members 440. The driving end of the first driving member 410 rotates around a first axis a. The grooved wheel assembly 420 is connected to the driving end of the first driving member 410. One end of the lifting rod 430 is mounted on the grooved wheel assembly 420. Each clamping member 440 includes a first end 441 and a second end 442. When the other end of the lifting rod 430 presses against the two first ends 441, the two second ends 442 move away from each other. When the other end of the lifting rod 430 moves away from the two first ends 441, the two second ends 442 move closer to each other.

[0049] The fourth axis d, the third axis c, the second axis b, and the first axis a are set parallel to each other.

[0050] The first driving component 410 is also configured as a motor, and the grooved wheel group 420 includes a first grooved wheel 421 and a second grooved wheel 422. The first grooved wheel 421 is connected to the output end of the motor for transmission, and the second grooved wheel 422 is fixedly connected to the first grooved wheel 421.

[0051] The motor drives the first grooved wheel 421 and the second grooved wheel 422 to rotate, thereby causing the lifting rod 430 to move up and down. The lifting rod 430 moves downward to press against the two first ends 441, or the lifting rod 430 moves upward to move away from the two first ends 441. Here, moving away from the two first ends 441 means that, relative to pressing against the two first ends 441, the lifting rod 430 moves upward to a certain height. At this time, the lifting rod 430 can have a certain contact with the two first ends 441, or it can completely disengage from the two first ends 441.

[0052] When the two second ends 442 come close to each other, the clamping mechanism 400 is in a closed state, thereby clamping the rice ball. In this embodiment, the two second ends 442 are defined as the material picking ends.

[0053] In this embodiment, the optimal closing angle of the clamping mechanism 400 can be preset based on multiple experiments, thereby controlling the clamping force of the clamping structure. On the one hand, it can prevent the rice ball from falling during the transfer process due to insufficient clamping force, and on the other hand, it can also reduce the damage and deformation of the rice ball caused by excessive clamping force.

[0054] After the two second ends 442 move away from each other, the gripping mechanism 400 is in the open state, thus placing the rice ball steadily in the tray 110.

[0055] Please refer to the following: Figure 4 and Figure 5The grooved wheel assembly 420 is provided with a sliding groove 4221, which extends along the axial direction of the first shaft a. The lifting rod 430 is provided with a sliding part corresponding to the sliding groove 4221, and the sliding part is slidably disposed in the sliding groove 4221.

[0056] Specifically, the groove 4221 is located on the side of the second groove wheel 422 away from the first groove wheel 421.

[0057] The slide 4221 includes at least a first slide section and a second slide section. The distance between the first slide section and the center of the first shaft a is defined as the first distance, and the distance between the second slide section and the center of the first shaft a is defined as the second distance. The second distance is not equal to the first distance. During the rotation of the slide 4221, the sliding part is always located at the lowest position of the slide 4221.

[0058] In this embodiment, the groove width of the slide 4221 can be set to a preset groove width, which is adapted to the outer diameter of the sliding part.

[0059] The first distance can be the distance between the centerline of the first slide section and the center of the first shaft a, and the second distance can be the distance between the centerline of the second slide section and the center of the first shaft a; or, the first distance can be the distance between the side wall of the first slide section near the first shaft a and the center of the first shaft a, and the second distance can be the distance between the side wall of the second slide section near the first shaft a and the center of the first shaft a; or, the first distance can be the distance between the side wall of the first slide section away from the first shaft a and the center of the first shaft a, and the second distance can be the distance between the side wall of the second slide section away from the first shaft a and the center of the first shaft a.

[0060] For example, the second distance is less than the first distance. When the sliding part is located in the first slide groove section, the lifting rod 430 descends, and when the sliding part is located in the second slide groove section, the lifting rod 430 rises.

[0061] It is understood that the slide 4221 may also include a third slide section, a fourth slide section, a fifth slide section and a sixth slide section, thereby changing the height of the lifting rod 430 to control the clamping angle of the clamping mechanism 400.

[0062] In practical applications, under the premise of meeting production needs, the stroke of the lifting mechanism 300 is controlled by the controller. That is, the lifting mechanism 300 should at least descend until the material picking end can pick up the rice ball, and the lifting mechanism 300 should at least rise until the material picking end can leave the bearing surface.

[0063] Please see Figure 1 Based on the above, this embodiment further explains the working principle of the rice ball transfer device as follows:

[0064] S100. Start the translation mechanism 200 to move the material picking end to the left side of the frame 100.

[0065] S200. Start the clamping mechanism 400 to open the material picking end.

[0066] S300. Start the lifting mechanism 300 to lower the material picking end to the material picking position.

[0067] S400. Control the clamping mechanism 400 to close the feeding end and clamp the rice ball.

[0068] S500. Start the lifting mechanism 300 to raise the material picking end.

[0069] S600. Start the translation mechanism 200 to move the picking end that grips the rice ball to the right side of the frame 100.

[0070] S700. Start the lifting mechanism 300 to lower the material picking end into the tray 110.

[0071] S800. Start the gripping mechanism 400 to open the feeding end and put down the rice ball.

[0072] In this embodiment, the rice ball is gripped by the closed state of the gripping mechanism 400, and then the rice ball is carried away by the lifting mechanism 300 and the translation mechanism 200. Finally, the rice ball is placed in the tray 110 by the open state of the gripping mechanism 400. This embodiment realizes the automatic transfer of rice balls by mechanical means, without manual operation, reducing the loss rate of rice balls, freeing producers from tedious transfer processes, and reducing the manufacturing cost of the factory.

[0073] Example 2

[0074] Please see Figure 4 and Figure 6 Based on Embodiment 1, this embodiment is improved in that the lifting rod 430 includes a body 431 and a rolling part 432. The rolling part 432 is installed at the end of the body 431 away from the grooved wheel group 420, and the rolling part 432 is rotatably connected to the body 431 about the rotation axis. The rotation direction of the rolling part 432 matches the pressing direction of the lifting rod 430.

[0075] Specifically, the first end 441 is configured as a rocker, the second end 442 is configured as a serrated claw, and the rolling part 432 rotates along the surface of the rocker, thereby smoothly pressing down the rocker and lifting the claw, so that the two claws move away from each other.

[0076] Furthermore, to prevent the lifting rod 430 from falling out of its travel range during the lifting process, this embodiment provides a limiting member above the lifting rod 430.

[0077] This embodiment utilizes the design of the rolling part 432 to improve the state transition efficiency of the clamping mechanism 400 and has a good influence on the stability of the clamping mechanism 400.

[0078] Example 3

[0079] Please see Figure 6 Based on Embodiment 1, this embodiment is improved in that the rice ball transfer device further includes an elastic element 500, which is supported between the two clamping elements 440. When the other end of the lifting rod 430 presses against the two first ends 441, the elastic element 500 deforms. When the other end of the lifting rod 430 leaves the two first ends 441, the elastic element 500 returns to its original shape.

[0080] In this embodiment, the elastic element 500 provides energy storage for the closing of the two gripping parts 440, so that the gripping mechanism 400 can steadily grip the rice ball and ensure that the rice ball will not fall due to external force during the transfer process.

[0081] Example 4

[0082] Please see Figure 1 and Figure 3 Based on Embodiment 1, this embodiment is improved in that the mounting bracket 310 is provided with a guide rail 311, and the machine head 340 is provided with a slider 3411 that cooperates with the guide rail 311. The slider 3411 is slidably disposed relative to the guide rail 311 in the second direction.

[0083] In this embodiment, the slider and guide rail 311 are located on the right side of the mounting frame 310. To further improve the lifting stability of this embodiment, a pulley 350 can also be added to the left side of the mounting frame 310 to ensure that this embodiment achieves linear movement in the vertical direction and is not prone to twisting, so that the rice ball can be placed in the tray 110 in the preset state.

[0084] Example 5

[0085] Please see Figure 1 and Figure 2 Based on Embodiments 1 to 4, this embodiment provides a rice ball production line, which includes a rice ball transfer device and a rice ball making device as described in the above embodiments. The rice ball transfer device is provided with a material picking end, and the material discharge position of the rice ball making device is within the movement range of the material picking end.

[0086] Understandably, the discharge position of the rice ball making device is configured as the first position, and the tray 110 is the second position, that is, the formed rice balls are transferred from the rice ball making device to the rice ball transfer device. When the tray 110 is full of rice balls, the full tray 110 is replaced with an empty tray 110 in preparation for the next rice ball transfer.

[0087] The aforementioned material-taking end consists of two second ends 442 of the clamping mechanism 400. When the two second ends 442 come close to each other, the clamping mechanism 400 is in a closed state, and the material-taking end clamps the rice ball.

[0088] The rice ball production line provided in this embodiment improves the automation level of rice ball production and transfer, reduces labor input costs, and is conducive to mass production.
