[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation plans:
[0033] The present embodiment discloses a fruit and vegetable rotary conveying device, which is mainly used to more accurately change the position of fruits and vegetables during the process of conveying fruits and vegetables, so that visual inspection equipment can perform comprehensive inspection on the fruits and vegetables for subsequent sorting of the fruits and vegetables.
[0034] See also Figure 1 and Figure 2 The fruit and vegetable rotary conveying device of this embodiment includes a transmission mechanism 10, an adjustment mechanism 20 and a linkage structure; the transmission mechanism 10 includes a chain group 12, a first rotation driving member 13 for driving the chain group 12 to move, and a plurality of rollers 11 arranged in parallel along the moving direction of the chain group 12; the rollers 11 are rotatably arranged on the chain group 12 to carry fruits and vegetables. When the chain group 12 moves, it drives the roller 11 to move along a predetermined track 40; the predetermined track 40 includes a first section 41 extending obliquely upward and a second section 42 extending laterally from the upper end of the first section 41 to the back of the first section 41; the adjustment mechanism 20 is arranged above the chain group 12 to adjust the position of the fruits and vegetables carried by the roller 11; the position of the linkage structure corresponds to the position of the second section 42, and when the roller 11 moves along the second section 42, the linkage structure contacts the roller 11 and forces the roller 11 to rotate.
[0035] Generally speaking, the drum 11 will be provided with a specific shape structure to limit the position of fruits and vegetables, so as to facilitate their carrying and transportation. However, in actual application scenarios, the movement of fruits and vegetables to the drum 11 is disordered, and often multiple fruits and vegetables are moved to the same drum 11 at the same time. In this embodiment, when the drum 11 drives multiple fruits and vegetables to move upward along the extension direction of the first section 41, among the multiple fruits and vegetables, for fruits and vegetables with inaccurate placement, since the support and limiting effect of the drum 11 is poor, these fruits and vegetables will roll down under the action of their own gravity, while for fruits and vegetables with accurate placement, the support and limiting effect of the drum 11 is better, and the drum 11 drives the fruits and vegetables to continue to move forward, thus ensuring that the placement position of the fruits and vegetables on the drum 11 meets expectations, which is conducive to the subsequent adjustment of the position of the fruits and vegetables according to the preset process.
[0036] When the roller 11 moves along the second section 42, the linkage structure contacts the roller 11 and forces the roller 11 to rotate. During the rotation of the roller 11, the fruits and vegetables are driven to roll, and the placement of the fruits and vegetables is changed, so that the fruits and vegetables can be photographed from multiple angles. Since the position of the fruits and vegetables has been adjusted to the preset position in the previous process, it is not easy for the fruits and vegetables to fall off the roller 11 or have a large-scale position deviation when they roll later.
[0037] In addition, the adjustment mechanism 20 of this embodiment is disposed above the chain set 12 to adjust the position of the fruits and vegetables carried by the roller 11, and further adjust the position of the fruits and vegetables to ensure that the position of the fruits and vegetables meets expectations.
[0038] In this embodiment, through the above-mentioned method, the position angle of fruits and vegetables can be changed more accurately during the fruit and vegetable transportation process, so that the visual shooting device can detect the fruits and vegetables in all directions.
[0039] Please combine Figure 1-Figure 3 In the embodiment, the chain set 12 includes a bracket plate 121, a first gear 123 rotatably arranged on one side of the bracket plate 121, and a roller chain 122 meshing with the first gear 123; the output end of the first rotating driving member 13 is connected to the first gear 123 to drive the first gear 123 to rotate, and the first gear 123 drives the roller chain 122 to move when it rotates; the roller 11 is rotatably arranged on the roller chain 122. Among them, the structure of the roller chain 122 is the prior art, and its structure is not described in detail here. The connection method between the roller 11 and the roller chain 122 can be an axial connection, and the connection position of the roller 11 and the roller chain 122 can be changed according to actual needs, as long as the two can be rotatably connected.
[0040] In this embodiment, the number of chain sets 12 is two, and the two chain sets 12 are symmetrically and spaced apart. The two ends of the rotating shaft of the roller 11 are rotatably arranged on the roller chains 122 of the two chain sets 12, respectively. The roller chains 122 of the two chain sets 12 drive the roller 11, which can make the movement and rotation of the roller 11 more stable. In other embodiments, the number of chain sets 12 can also be one.
[0041] In this embodiment, a limiting structure is provided on one side of the bracket plate 121 facing the roller chain 122 , and the limiting structure abuts against the roller chain 122 to support the roller chain 122 . The roller chain 122 can slide on the limiting structure to improve the stability of the movement of the roller chain 122 .
[0042] In this example, see Figure 2 The limiting structure includes a limiting plate 14 protruding from the bracket plate 121; the extension direction of the limiting plate 14 is parallel to the extension direction of the first section 41, and the roller chain 122 abuts against the top surface of the limiting plate 14. Under the support and guidance of the limiting plate 14, the roller chain 122 can move upward relatively smoothly and obliquely, thereby driving the roller 11 to move along the extension direction of the first section 41 of the preset trajectory.
[0043] Please combine Figure 3-Figure 6In this embodiment, the rotating shaft of the drum 11 is provided with a second gear 111, and the second gear 111 rotates synchronously with the rotating shaft of the drum 11. Specifically, the second gear 111 is sleeved on the rotating shaft of the drum 11, and the second gear 111 and the rotating shaft of the drum 11 can rotate synchronously by means of a key and a slot.
[0044] See also Figure 2 and Figure 3 The linkage structure includes a rack 50 disposed on the bracket plate 121, the position of the rack 50 corresponds to the position of the second section 42, and the length direction of the rack 50 is parallel to the extension direction of the second section 42. Preferably, the rack 50 is located below the second gear 111. On the one hand, the rack 50 supports the rotating shaft of the drum 11 through the second gear 111, and the rotating shaft of the drum 11 supports the roller chain 122, so that the roller chain 122 can drive the drum 11 to move smoothly along the extension direction of the second section 42. On the other hand, during the movement of the drum 11 along the second section 42, the second gear 111 is meshed with the rack 50, and the rack 50 forces the gear to drive the drum 11 to rotate, so that there is no need to set up an additional driving device to drive the drum 11 to rotate, which is conducive to simplifying the structure. Of course, in other embodiments, the position of the rack 50 can be changed according to actual needs, as long as the rack 50 and the second gear 111 can be meshed. For example, the rack 50 can be arranged above the second gear 111.
[0045] like Figure 1 As shown, in this embodiment, the top surface of the bracket plate 121 is provided with a plurality of installation locations (in Figure 1 The adjustment mechanism 20 is installed at one of the multiple installation positions. The adjustment mechanism 20 can adjust its installation position according to actual needs, for example, Figure 2 As shown, the position of the adjustment mechanism 20 can correspond to the top position of the first section 41, so that before the roller 11 moves to the second section 42 of the preset trajectory, the fruits and vegetables can be shaped and the positions of the fruits and vegetables can be adjusted to ensure that the positions of the fruits and vegetables meet expectations. In this way, when the roller 11 enters the second section 42, the visual inspection device can immediately inspect the fruits and vegetables transported by the roller 11 without adjusting the positions of the fruits and vegetables. Figure 1 As shown, the position of the adjustment mechanism 20 may correspond to the position of the second section 42, so that the position of the fruits and vegetables can be adjusted after the fruits and vegetables roll, ensuring that no significant positional deviation occurs after the fruits and vegetables roll.
[0046] In this example, see Figure 1The adjustment mechanism 20 includes a mounting frame 22, a second rotating driving member 23 disposed on the mounting frame 22, and a positioning drum 21 disposed at the output end of the second rotating driving member 23. The positioning drum 21 is driven to rotate by the second rotating driving member 23, so that the positioning drum 21 adjusts the position of the fruits and vegetables carried by the drum 11. Specifically, the mounting frame 22 is detachably fixed to the mounting position on the top surface of the bracket plate 121 by fasteners, and the second rotating driving member 23 can be a motor, a rotary cylinder, etc.; preferably, the second rotating driving member 23 is a motor, and the positioning drum 21 is sleeved on the output shaft of the motor, and the motor drives the positioning drum 21 to rotate. The positioning drum 21 can rotate in the forward direction or in the reverse direction, and the rotation direction of the positioning drum 21 is not limited. The rotation axis of the positioning drum 21 is parallel to the rotation axis of the drum 11. When a plurality of fruits and vegetables are accumulated in the same drum 11, the position-adjusting drum 21 can adjust the positions of the fruits and vegetables so that the plurality of fruits and vegetables are arranged in parallel in a relatively neat manner, or the plurality of fruits and vegetables are arranged one by one in sequence.
[0047] In other embodiments, the second rotating drive member 23 is slidably mounted on the mounting frame 22 via a slide rail assembly (not shown in the figure), and a spring (not shown in the figure) is disposed between the bottom surface of the second rotating drive member 23 and the top surface of the bracket plate 121. When the volume of fruits and vegetables is large, the fruits and vegetables squeeze the positioning drum 21, forcing the positioning drum 21 to move upward, and the positioning drum 21 drives the second rotating drive member 23 to move upward. The spring is elastically deformed by the pulling force of the second rotating drive member 23. When the fruits and vegetables pass under the positioning drum 21, the elastic force of the spring can force the second rotating drive member 23 and the positioning drum 21 to move downward and return to their original positions. In this way, the adjustment mechanism 20 can be used to adjust the positions of fruits and vegetables of various sizes, and has a wide range of applicability.
[0048] In this example, see Figure 5 The diameter of the drum 11 gradually decreases from the middle of the drum 11 to the two ends of the drum 11, so that the middle part of the drum 11 is concave, and the middle part of the drum 11 can limit the fruits and vegetables. The fruits and vegetables are limited in the middle part of the drum 11, and the axial displacement of the fruits and vegetables along the drum 11 is limited. In addition, the middle part of the fruits and vegetables can also be used to limit fruits and vegetables of different sizes, and the application range is wide.
[0049] Please refer again Figure 1 In order to prevent fruits and vegetables from entering the roller chain 122 and affecting the movement of the roller chain 122 , the bracket plate 121 of this embodiment is also provided with a baffle 1211 , and the baffle 1211 is located directly above the roller chain 122 to prevent fruits and vegetables from entering the roller chain 122 .
[0050] The embodiment disclosed in this specification is only an example of the unilateral features of the utility model, and the protection scope of the utility model is not limited to this embodiment. Any other functionally equivalent embodiments fall within the protection scope of the utility model. For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the utility model.
