[0060] Figure 1 is a structural schematic diagram of a sorting system provided in an embodiment of the present application, Figure 2 yes Figure 1 The structural diagram in the first perspective, Figure 3 yes Figure 1 Structural diagram at a second viewing angle. The present application embodiment provides a sorting system, including a sowing device 1 and a sowing wall 2. The sowing device 1 may also be referred to as a three-dimensional sorting machine, which may specifically include a delivery mechanism 10 and a motion mechanism 20, wherein the delivery mechanism 10 is configured to carry a target object and deliver the target object.

[0061] The moving mechanism 20 is connected to the delivery mechanism 10, and the moving mechanism 20 is configured to drive the delivery mechanism 10 to move so that the delivery mechanism 10 can move to the sowing position. For example, the moving mechanism 20 may include a horizontal movement module 20a and a vertical movement module 20b. The horizontal movement module 20a can drive the delivery mechanism 10 to move along the length direction of the sowing device 1, and the vertical movement module 20b can drive the delivery mechanism 10 to move along the height direction of the sowing device 1, so that the delivery mechanism 10 moves to the sowing position, thereby delivering the target item on the delivery mechanism 10 to the designated position.

[0062] Exemplarily, the sowing equipment 1 may include a gantry 30, a motion mechanism 20 and a delivery structure are arranged in the gantry 30, the horizontal motion module 20a can be connected to the vertical motion module 20b to drive the vertical motion module 20b to move along the length direction of the gantry 30, and the delivery mechanism 10 is arranged on the vertical motion module 20b, so that it can move along the length direction of the gantry 30 with the vertical motion module 20b under the drive of the horizontal motion module 20a, and the vertical motion module 20b can drive the delivery mechanism 10 to move along the height direction of the gantry 30, so that the delivery mechanism 10 moves to the sowing position.

[0063] The horizontal motion module 20a and the vertical motion module 20b may be specifically described in the related art and will not be described in detail here.

[0064] The seeding wall 2 is arranged on at least one side of the seeding device 1. For example, the seeding wall 2 can be arranged on the seeding device 1 along the width direction (refer to Figure 1 Alternatively, sowing walls 2 may be provided on both sides of the sowing device 1 along the width direction.

[0065] For example, the sowing device 1 may include a first side and a second side opposite to each other in the width direction, wherein the first side is provided with a first sowing wall 21, and the second side is provided with a second sowing wall 22. The delivery mechanism 10 may deliver the target object to the first sowing wall 21, or may deliver the target object to the second sowing wall 22, so as to achieve sowing of the target object, such as sorting. Exemplarily, the sowing wall 2 may include a shelf and a turnover container arranged on the shelf. The shelf may include a multi-layer cargo position 2a arranged in the height direction, and each layer of cargo position 2a may include a plurality of cargo positions arranged in the length direction of the sowing wall 2 (refer to Figure 1 The cargo positions 2a are arranged side by side (in the y direction), and the turnover containers are placed on each cargo position 2a and are configured to receive the target items delivered by the delivery mechanism 10.

[0066] It should be noted that the turnover container may include but is not limited to a material box, a carton or a cage, and the target item corresponding to a sorting task may correspond to a turnover container.

[0067] In addition, the target item may include but is not limited to the goods themselves, the goods with packaging boxes, the packages containing the goods, etc.

[0068] In some examples, the sowing device 1 can cooperate with a handling robot (e.g., a sorting robot) to perform a sowing operation (e.g., a sorting operation) of goods. Taking the sorting task as an example, the sorting robot can receive the target item from the workstation and carry the target item to the delivery position of the sowing device 1 for delivery. For example, the sorting robot can be a flap robot, a belt sorting robot, a liftable tray robot, or other types of robots. The specific form of the sorting robot is not limited in the embodiments of the present application.

[0069] In some examples, the sowing device 1 can also be manually sorted by sorting personnel, that is, the sorting personnel directly deliver the target objects to the delivery mechanism 10, and then the delivery mechanism 10 delivers the received target objects to the corresponding turnover container.

[0070] In some other examples, the seeding device 1 may include a cache mechanism 40, and the sorting robot or sorting personnel may place the target items on the sorting robot on the cache mechanism 40, and then transfer the target items to the delivery mechanism 10 through the cache mechanism 40, so as to shorten the waiting time of the sorting robot and improve the sorting efficiency. For example, the cache mechanism 40 may be a structure such as a transmission belt, and the target items on the transmission belt may be delivered to the delivery mechanism 10 in the direction of horizontal transmission.

[0071] After receiving the target object, the delivery mechanism 10 of the sowing equipment 1 can move to the sowing position in the door frame 30 driven by the moving mechanism 20, and then deliver the target object to the turnover container of the sowing wall 2 to complete the sowing of the target object, such as sorting.

[0072] In some examples, the delivery mechanism 10 may be one or more. For example, the delivery structure may be multiple, and multiple delivery mechanisms 10 may alternately move to the delivery position, receive the target items on the sorting robot or the cache mechanism 40, and each independently move to the corresponding sowing position, and deliver the corresponding target items to the designated turnover container, so that sorting of multiple target items can be achieved at the same time, thereby improving the sorting efficiency of the sowing equipment 1.

[0073] It can be seen that in practice, the delivery mechanism 10 is used frequently, so the reliability of the delivery mechanism 10 is very important. In the related art, the delivery mechanism 10 is a belt structure. During sorting, the delivery mechanism 10 uses a belt horizontal transmission method to deliver the goods on the belt to the turnover container.

[0074] For example, the sorting robot can transfer the target item to the receiving position of the belt structure. Then, in order to improve the delivery efficiency, the belt in the belt structure can accelerate the horizontal movement, and accelerate the target item at the receiving position to the corresponding turnover container. When the target item at the receiving position reaches the end of the belt structure, the target item can move into the turnover container under inertia and belt transmission.

[0075] In the above delivery process, the belt structure needs to drive the target item to the end, and then move it into the turnover box under the action of inertia, so the delivery time is relatively long. In addition, because the receiving position of the belt structure for receiving the target item will be different each time, the speed of the target item when it reaches the end of the belt structure will be different, which will cause the landing point of the target item to be different, making the landing point of the target item uncontrollable and affecting the delivery effect. For example, the target item may fall to the edge of the turnover box, causing the center of gravity of the turnover box to deviate, or even fall outside the turnover box, resulting in delivery failure.

[0076] The embodiment of the present application provides a delivery mechanism 10, which is provided with a driving member 100 and a transmission assembly 200, and the driving member 100 drives the transmission assembly 200 to rotate, so that the object carrier 300 provided on the transmission assembly 200 is flipped, so that the target object on the object carrier 300 is delivered to the turnover container, that is, the delivery mechanism 10 of the embodiment of the present application adopts a flipping method to deliver the target object, which is equivalent to a belt transmission method, shortens the delivery time, and improves the sowing efficiency of the sowing device 1. In addition, the flipping delivery method can ensure the consistency of the delivery point of the target object, so that the target object can be stably delivered to the turnover box, and the controllability of the delivery position is ensured, thereby improving the sowing effect of the sowing device 1.

[0077] The structure of the delivery mechanism 10 provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0078] Figure 4 is a structural diagram of a delivery mechanism 10 provided in one embodiment of the present application. Figure 5 is a schematic diagram of the structure of the delivery mechanism 10 provided in an embodiment of the present application in the second state. Figure 6 is a schematic diagram of the structure of the delivery mechanism 10 in the third state provided by an embodiment of the present application. Figure 7 is a structural principle diagram of another delivery mechanism 10 provided in an embodiment of the present application in a first state. Figure 8 is a structural principle diagram of another delivery mechanism 10 provided in an embodiment of the present application in a second state. Fig. 9 1 is a schematic diagram of the structure of another delivery mechanism 10 in the third state provided by an embodiment of the present application. Figures 4 to 9As shown, an embodiment of the present application provides a delivery mechanism 10 , including a driving member 100 , a transmission assembly 200 and an object carrier 300 .

[0079] In some examples, the driving member 100 may include, but is not limited to, a rotary motor and the like.

[0080] Reference Figures 4 to 6 As shown, the transmission assembly 200 includes a fixing member 210, a first connecting member 220 and a second connecting member 230. One end of the first connecting member 220 is connected to the driving member 100 and is rotatably arranged on the fixing member 210, one end of the second connecting member 230 is rotatably connected to the other end of the first connecting member 220, the other end of the second connecting member 230 is movably arranged on the fixing member 210, and the other end of the second connecting member 230 has a degree of freedom at least in the delivery direction. The first connecting member 220 is configured to rotate under the drive of the driving member 100 to drive the second connecting member 230 to rotate.

[0081] It should be noted that the delivery direction refers to the arrangement direction of the delivery mechanism 10 and the position to be delivered, such as the turnover container in the sowing wall 2, that is, the direction of the delivery mechanism 10 toward the position to be delivered. Figures 1 to 3 As shown, the delivery mechanism 10 and the delivery position of the sowing wall 2 are arranged along the width direction (ie, x direction) of the sowing device 1. In this example, the delivery direction is the x direction, ie, the horizontal direction.

[0082] In some examples, the delivery position has a certain tilt angle with the delivery mechanism 10, so the delivery mechanism 10 needs to be tilted, and the delivery direction is a direction with an angle greater than 0° with the horizontal direction. The following description takes the delivery direction as the x direction as an example.

[0083] In addition, the other end of the second connecting member 230 has at least two degrees of freedom in the delivery direction, one of which is that the other end of the second connecting member 230 can move horizontally along the delivery direction, i.e., the x direction. Another case is that the other end of the second connecting member 230 can move in a direction having a non-0° angle with the x direction, for example, can move in the direction of an arc track, and has a component in the x direction.

[0084] For the convenience of description, the two opposite ends of the first connecting member 220 along the length direction can be respectively referred to as the first end A and the second end B. The first end A is the end of the first connecting member 220 used to connect to the driving member 100, and the second end B is the end of the first connecting member 220 connected to the second connecting member 230.

[0085] In some examples, the driving member 100 may include a driving body 110 and a connecting shaft 120. The driving body 110 may be fixed to the vertical moving module of the motion mechanism 20. One end of the connecting shaft 120 is connected to the driving body 110, and the other end may be inserted into the fixing member 210. For example, a first fixing hole may be provided on the fixing member 210, and the connecting shaft 120 may be inserted into the first fixing hole and may rotate in the first fixing hole. Figures 7 to 9 As shown, point M is the driving rotation point of the driving member 100 , that is, the position where the first connecting member 220 is used to connect with the driving member 100 .

[0086] In some examples, the first end A of the first connecting member 220 can be fixedly connected to the connecting shaft 120. For example, a second fixing hole can be opened on the first end A of the first connecting member 220, and one end of the connecting shaft 120 is fixedly inserted into the second fixing hole, that is, one end of the connecting shaft 120 is fixedly connected to the second fixing hole. In this way, the driving body 110 can drive the connecting shaft 120 to rotate to drive the first connecting member 220 to rotate around the axis of the connecting shaft 120.

[0087] In some examples, the first end A of the first connecting member 220 is movably disposed on the fixing member 210 through the driving member 100. For example, the driving member 100 may include a fastener such as a nut 130, the connecting shaft 120 is movably inserted into the fixing member 210, the first end A of the first connecting member 220 is fixedly sleeved on the connecting shaft 120, and the nut 130 is fixedly sleeved on the connecting shaft 120 and is located on the side of the first end A of the first connecting member 220 away from the fixing member 210, so that the first end A of the first connecting member 220 is attached to the surface of the fixing member 210 through the nut 130. When the driving body 110 drives the connecting shaft 120 to rotate, the first end A of the first connecting member 220 can rotate around the axis of the connecting shaft 120, so that the first connecting member 220 can rotate along the surface of the fixing member 210, thereby improving the rotation stability of the first connecting member 220.

[0088] In some examples, the fixing member 210 may include a first side surface 211 and a second side surface 212 that are disposed opposite to each other, the transmission assembly 200 is located on the first side surface 211, the driving body 110 is located on the second side surface 212, one end of the connecting shaft 120 is connected to the driving body 110, and the other end passes through the fixing member 210 and is located on the first side surface 211, one end of the first connecting member 220 is connected to one end of the connecting shaft 120 located on the first side surface 211, for example, the nut 130 located on the connecting shaft 120 is fixed to the connecting shaft 120 located on the first side surface One end of the surface 211 is used to limit the first end A of the first connecting member 220 to the first side surface 211 of the fixing member 210, so that the first connecting member 220 drives the second connecting member 230 to move along the first side surface 211 of the fixing member 210 without being affected by the driving body 110. In other words, the driving body 110 and the transmission assembly 200 are arranged on different sides of the fixing member 210, providing a suitable space for the movement of the transmission assembly 200, so that the flipping of the transmission assembly 200 and the object carrier 300 is smoother and more reliable.

[0089] Exemplarily, the first connecting member 220 may be a rod-shaped member, and the fixing member 210 may be a plate-shaped member.

[0090] Reference Figure 5 As shown, in addition, for the convenience of description, the two opposite ends of the second connecting member 230 along the length direction are called the third end C and the fourth end D, wherein the third end C of the second connecting member 230 is rotatably connected to the second end B of the first connecting member 220, for example, the third end C of the second connecting member 230 is hinged to the second end B of the first connecting member 220, and the fourth end D of the second connecting member 230 is movably arranged on the fixing member 210, so that the fourth end D of the second connecting member 230 can have freedom along the horizontal direction (for example, the x direction), and can be equivalent to the rotation of the fixing member 210.

[0091] In this way, when the first connecting member 220 rotates around the axis of the connecting shaft 120, it can drive the second connecting member 230 to flip relative to the fixing member 210. For example, the third end C of the second connecting member 230 can rotate around the fourth end D along the surface of the fixing member 210.

[0092] It should be noted that the "one end" and "the other end" of a component involved in the embodiments of the present application do not specifically refer to the endpoints of a component, but are intended to emphasize the relative positional relationship between the "one end" and the "other end", that is, to emphasize that the "one end" and the "other end" are not the same position of a component. "One end" and "the other end" can be the ends of a component, or they can be the middle part with a preset distance from the end of a component. The embodiments of the present application do not limit the specific positions of the "one end" and "the other end" of a component. For the convenience of description, the embodiments of the present application specifically use the "one end" and "the other end" of a component as an example to illustrate the structure of the delivery mechanism 10.

[0093] Taking the second connecting member 230 as an example, one end of the second connecting member 230 is rotatably connected to one end of the first connecting member 220, and the other end of the second connecting member 230 is movably arranged on the fixing member 210, which can be specifically to express that the first connecting member 220 and the fixing member 210 are respectively arranged at different positions of the second connecting member 230 along the length direction. Among them, one end of the second connecting member 230 can be the C end, or it can be other positions with a certain distance from the C end along the length direction, and the other end of the second connecting member 230 can be the D end, or it can be other positions with a certain distance from the D end along the length direction. The embodiment of the present application is specifically combined with the accompanying drawings, with one end and the other end of the second connecting member 230 respectively being the ends of the second connecting member 230 in order to explain the structure of the delivery mechanism 10.

[0094] The object carrier 300 is connected to the second connecting member 230 , and is configured to carry a target object, and is turned over under the drive of the second connecting member 230 to deliver the target object.

[0095] In some examples, the object carrier 300 can be parallel to the second connecting member 230, so that the angle of the object carrier 300 is consistent with the angle of the second connecting member 230, so that the flipping angle of the object carrier 300 can be directly determined by controlling the flipping angle of the second connecting member 230, making the control process of the flipping angle of the object carrier 300 by the entire delivery mechanism 10 simpler and more intuitive.

[0096] Of course, in other examples, the object carrier 300 may have a certain angle with the second connecting member 230. By simply inputting the angle into the controller of the driving member 100 in advance, the angle can be taken into account when controlling the rotation of the driving member 100, so that when the second connecting member 230 flips to the target angle, the object carrier 300 reaches the delivery angle.

[0097] Exemplarily, the sorting robot or the caching mechanism 40 can deliver the target item to the carrier 300, and the driving member 100 drives the first connecting member 220 to rotate to drive the second connecting member 230 to rotate, so that the carrier 300 is flipped along with the second connecting member 230 until the carrier 300 is flipped to the delivery angle, and the target item located on the carrier 300 can fall into the corresponding turnover container.

[0098] It is understandable that the object carrier 300 has a carrying surface 310, which is configured to carry the target object. When the object carrier 300 is turned over with the second connector 230, the direction of the carrying surface 310 changes accordingly, so that the object carrier 300 switches between different working states.

[0099] For example, in order to enable the delivery mechanism 10 to dock with the turnover containers on both sides of the sowing device 1, the second connecting member 230 can be flipped between the first position and the second position. When the second connecting member 230 is in the first position, the bearing surface 310 of the object carrier 300 faces the first side (refer to Figure 5 When the second connecting member 230 is in the second position, the carrying surface 310 of the object carrier 300 faces the second side (refer to Figure 6 In this way, the same delivery mechanism 10 can be docked with the turnover containers on both sides according to actual needs.

[0100] Reference Figure 7 As shown, for example, when the object carrier 300 needs to receive the target item on the sorting robot or the cache mechanism 40, the driving member 100 can drive the second connecting member 230 to rotate to a horizontal position through the first connecting member 220, and the object carrier 300 is rotated to a horizontal position under the drive of the second connecting member 230, that is, the object carrier 300 of the delivery mechanism 10 is in the first state, and the object carrier 300 is driven by the moving mechanism 20 to move to the delivery position of the sorting system to receive the target item on the sorting robot or the cache mechanism 40.

[0101] Reference Figure 5 and Figure 8 As shown, when the target turnover container is the turnover container on the first sowing wall 21, after the carrier 300 receives the target item, it can be moved to the sowing position under the drive of the moving mechanism 20, and when the driving member 100 drives the first connecting member 220 to rotate upward, the second connecting member 230 can be rotated upward under the drive of the first connecting member 220, until the second connecting member 230 rotates to the first position, the carrying surface 310 of the carrier 300 flips to the right (i.e., the first side) to the first delivery angle, that is, the carrier 300 of the delivery mechanism 10 is in the second state, thereby delivering the target item on the carrier 300 to the turnover container of the first sowing wall 21 of the sowing equipment 1.

[0102] Reference Figure 6 and Fig. 9 As shown, when the target turnover container is the turnover container on the second sowing wall 22, after the carrier 300 receives the target item, it can be moved to the sowing position under the drive of the moving mechanism 20, and when the driving member 100 drives the first connecting member 220 to rotate downward, the second connecting member 230 can be rotated downward under the drive of the first connecting member 220 until the second connecting member 230 rotates to the second position, and the carrying surface 310 of the carrier 300 flips to the left (i.e., the second side) to the second delivery angle, that is, the carrier 300 of the delivery mechanism 10 is in the third state, thereby delivering the target item on the carrier 300 to the turnover container of the second sowing wall 22 of the sowing equipment 1.

[0103] In some examples, the second connector 230 of the delivery mechanism 10 can move from a horizontal position to a first position, so that the object carrier 300 switches from a first state to a second state, and the delivery mechanism 10 delivers the target object to the turnover container on the first side. Alternatively, the second connector 230 can move from a horizontal position to a second position, so that the object carrier 300 switches from a first pile body to a third state, and the delivery mechanism 10 delivers the target object to the turnover container on the second side.

[0104] It should be noted that, in some examples, when the object carrier 300 is flipped to the delivery angle, the target item can fall directly into the turnover container through the object carrier 300. For example, when the outer edge of the object carrier 300 is located above the turnover container, such as above the front end of the turnover container, the target item can fall into the turnover container through the edge of the object carrier 300.

[0105] In some examples, when the object carrier 300 is flipped to the delivery angle, the target item can be thrown into the turnover container by relying on the inertia provided by the flipping speed of the object carrier 300. During the throwing process, the target item has a horizontal displacement. In this way, the object carrier 300 can be set at a certain horizontal distance from the turnover box. For example, the delivery mechanism 10, such as the object carrier 300, does not need to be extended into the seeding wall 2 for delivery, thereby ensuring the movement stability of the delivery mechanism 10, the stability of the turnover container on the seeding wall 2, and the storage density of the seeding wall 2.

[0106] It is understandable that the main determining factors of the horizontal displacement of the thrown target object are the turning speed of the object carrier 300 and the height of the target object. The turning speed of the object carrier 300 is determined by the rotation speed of the driving member 100, and the height of the target object is determined by the height of the object carrier 300 when it is turned to the delivery angle, and the height of the object carrier 300 when it is turned to the delivery angle is related to the setting height of the delivery mechanism 10 and the delivery angle, and the delivery angle can be determined by controlling the control parameters of the driving member 100.

[0107] In this way, the embodiment of the present application drives the second connecting member 230 of the transmission assembly 200 to rotate through the driving member 100 to realize the flipping of the carrier 300, and delivers the target item into the turnover container by flipping. Compared with the belt transmission method, the consistency of the delivery point of the target item can be guaranteed, so that the target item can be stably delivered to the turnover box, and the controllability of the delivery position is guaranteed, thereby improving the sowing effect of the sowing equipment 1.

[0108] In addition, compared with delivering the target object by belt transmission, delivering the target object into the turnover box by flipping the object carrier 300 shortens the delivery time and improves the sowing efficiency of the sowing device 1.

[0109] In some examples, the object carrier 300 may be directly fixed to the second connecting member 230 to simplify the structure and improve assembly efficiency.

[0110] Reference Figure 4 As shown, in other examples, a mounting member 400 such as a mounting plate can be fixed to the second connecting member 230. For example, one end of the mounting plate is fixed to the second connecting member 230, and the other end of the mounting plate is fixed to the object carrier 300, so that a certain distance is maintained between the object carrier 300 and the transmission component 200, thereby ensuring that the transmission component 200 does not interfere with the object carrier 300 during movement, thereby ensuring the movement reliability of the transmission component 200 and the object carrier 300.

[0111] As one of the setting methods, in order to enable the fourth end D of the second connecting member 230 to automatically move relative to the fixing member 210, a sliding groove (not shown in the figure) can be set on the fixing member 210, and the fourth end D of the second connecting member 230 can be slidably set in the sliding groove, so that the fourth end D of the second connecting member 230 can move in the sliding groove during the rotation of the first connecting member 220, thereby ensuring that the second connecting member 230 can stably rotate under the drive of the first connecting member 220, so as to realize the flipping of the object carrier 300.

[0112] Exemplarily, a mounting portion such as a slider or a roller may be provided at the fourth end D of the second connecting member 230 , and the fourth end D of the second connecting member 230 is rotatably arranged with the mounting portion.

[0113] When the first connecting member 220 rotates, the second connecting member 230 can rotate around the fourth end D of the second connecting member 230, and the mounting portion on the second connecting member 230 moves along the slide groove to ensure the freedom of the second connecting member 230 in the horizontal direction.

[0114] For example, when the first connecting member 220 rotates upward from the horizontal position under the drive of the driving member 100, the second connecting member 230 can rotate upward relative to the mounting portion, and the mounting portion is retracted to the left under the drive of the second connecting member 230, so that the object carrier 300 is flipped to the first delivery angle, so that the target object on the object carrier 300 is dropped into the turnover container on the first side. It can be understood that in the first delivery position, the carrying surface 310 of the object carrier 300 faces the first side.

[0115] For another example, when the first connecting member 220 rotates downward from the horizontal position under the drive of the driving member 100, the second connecting member 230 can rotate downward relative to the mounting portion, and the mounting portion is retracted to the left under the drive of the second connecting member 230, so that the object carrier 300 is flipped to the second delivery angle, so that the target object on the object carrier 300 is dropped into the turnover container on the second side. It can be understood that at the second delivery angle, the carrying surface 310 of the object carrier 300 faces the second side.

[0116] In some examples, the slide groove can be set as an arc groove to adapt to the movement trajectory of the fourth end D of the second connecting member 230 during the rotation process, thereby ensuring that the second connecting member 230 can rotate stably without getting stuck.

[0117] Reference Figures 4 to 6 As shown, in order to realize that the fourth end D of the second connecting member 230 can automatically move relative to the fixing member 210, in another setting, the transmission assembly 200 may include a third connecting member 240, one end of the third connecting member 240 is rotatably connected to the second connecting member 230, and the other end of the third connecting member 240 is rotatably connected to the fixing member 210, so that the second connecting member 230 can move equivalent to the fixing member 210.

[0118] Reference Figure 5 As shown, for the convenience of description, the two opposite ends of the third connecting member 240 along the length direction are respectively referred to as the fifth end E and the sixth end F, wherein the fifth end E of the third connecting member 240 is rotatably connected to the fourth end D of the second connecting member 230, for example, the fifth end E of the third connecting member 240 can be hinged to the fourth end D of the second connecting member 230 through a hinge shaft, and the fifth end E of the third connecting member 240 is rotatably connected to the fixing member 210, for example, the fifth end E of the third connecting member 240 can be hinged to the fixing member 210 through a hinge shaft.

[0119] The second connecting member 230 is configured to flip under the constraints of the first connecting member 220 and the third connecting member 240 to drive the object carrier 300 to flip. For example, the driving member 100 can drive the first connecting member 220 to rotate, the third end C of the second connecting member 230 can rotate around the fourth end D driven by the first connecting member 220, and the third connecting member 240 can rotate around the sixth end F driven by the fourth end D of the second connecting member 230.

[0120] For example, refer to Figure 5 As shown, when the first connecting member 220 rotates upward from a horizontal position under the drive of the driving member 100, the second connecting member 230 rotates upward and drives the third connecting member 240 to rotate left until the second connecting member 230 rotates to the first position, and the object carrier 300 flips to the first delivery angle, so that the object carrier 300 is in the second state.

[0121] For example, refer to Figure 6 As shown, when the first connecting member 220 rotates downward from a horizontal position under the drive of the driving member 100, the second connecting member 230 rotates downward and drives the third connecting member 240 to rotate leftward until the second connecting member 230 rotates to the second position and the object carrier 300 flips to the second delivery angle.

[0122] In this way, the fourth end D of the second connecting member 230 can have freedom in both the horizontal direction (such as the x direction) and the vertical direction (such as the z direction) under the action of the third connecting member 240, so that the second connecting member 230 can rotate stably under the drive of the first connecting member 220 without getting stuck.

[0123] In addition, the third connecting member 240 is provided so that the fourth end D of the second connecting member 230 can move along an arc track, thereby reducing the size of the delivery mechanism 10 in the horizontal direction, such as the width direction. In addition, the third connecting member 240 also plays a stable supporting role for the second connecting member 230, making the structure of the transmission assembly 200 more stable.

[0124] Reference Figures 7 to 9 As shown, based on the above, it can be known that when the second connecting member 230 rotates from the horizontal position to the first position, the carrier 300 flips to the first delivery angle, and the target item located on the carrier 300 can be delivered to the turnover container on the first side; when the second connecting member 230 rotates from the horizontal position to the second position, the carrier 300 flips to the second delivery angle, and the target item located on the carrier 300 can be delivered to the turnover container on the second side.

[0125] The first position is located at the upper side of the first surface, and the second position is located at the lower side of the first surface. It can be understood that the first surface is a delivery surface that passes through the second connecting member 230 and is away from one end of the first connecting member 220.

[0126] The delivery surface refers to a plane parallel to the delivery direction and parallel to the carrying surface 310 when the object carrier 300 is in a non-delivery state, such as a horizontal state. For example, when the delivery direction is a horizontal direction, i.e., the x direction, the delivery surface is a horizontal plane parallel to the x direction, and the first surface is a horizontal plane passing through the fourth end D of the second connecting member 230, referring to Figure 7 The middle Q plane is shown.

[0127] In some examples, when the delivery direction is an inclined direction having a non-0° angle with the horizontal direction, such as the x direction, the delivery surface is an inclined surface having a non-0° angle with the horizontal plane, and the first surface is an inclined surface passing through the fourth end D of the second connecting member 230, and when the object carrier 300 is in a non-delivery state, such as a horizontal state, the first surface is parallel to the carrying surface 310. The embodiment of the present application is specifically described by taking the delivery surface as a horizontal plane as an example.

[0128] It is understandable that when the second connecting member 230 moves, the movement trajectory of the end of the second connecting member 230 away from the first connecting member 220, i.e., the D end, has a component in the z direction, and the position of the first surface changes continuously in the z direction during the movement of the second connecting member 230.

[0129] Reference Figure 7 As shown, illustratively, when the second connecting member 230 is in a horizontal position, it can be located on the first surface Q. For example, when the delivery mechanism 10 is working, the second connecting member 230 can be driven by the first connecting member 220 to rotate upward in a direction away from the first surface Q until the second connecting member 230 reaches the first position (refer to Figure 8 As shown), the object carrier 300 is flipped to a first delivery angle so that the target object can be delivered to the turnover container on the first side.

[0130] For another example, the second connecting member 230 may be driven by the first connecting member 220 to rotate downward in a direction away from the first surface Q until the second connecting member 230 reaches the second position (refer to Fig. 9 As shown), the object carrier 300 is flipped to a second delivery angle so that the target object can be delivered to the turnover container on the second side.

[0131] In some examples, when the second connecting member 230 is in the first position, a first angle is formed between the second connecting member 230 and the first surface Q (see Figure 8 α1), that is, the rotation angle of the second connecting member 230 from the horizontal position to the first position is α1, and there is a first inclination angle between the bearing surface 310 and the first surface Q (refer to Figure 8 β1), that is, the rotation angle of the first bearing surface 310 from the first state to the second state is β1; when the second connecting member 230 is in the second position, there is a second angle between the second connecting member 230 and the first surface Q (refer to Fig. 9 α2), that is, the rotation angle of the second connecting member 230 from the horizontal position to the second position is α2, and there is a second inclination angle between the bearing surface 310 and the first surface Q (refer to Fig. 9 β2 in the figure), that is, the rotation angle of the first bearing surface 310 from the first state to the third state is β2.

[0132] Exemplarily, the first delivery angle may be the first tilt angle, and the second delivery angle may be the second tilt angle.

[0133] Among them, the first angle is equal to the second angle, and the first inclination angle has a first preset relationship with the second inclination angle. In other words, when the second connecting member 230 rotates to an angle symmetrical with respect to the first surface Q, the inclination angle of the bearing surface 310 relative to the first surface Q has a specific relationship, for example, the difference between the first inclination angle and the second inclination angle is less than or equal to 10°. In this way, when the second connecting member 230 rotates upward or downward at the same angle, it can be ensured that the difference between the first delivery angle and the second delivery angle of the object carrier 300 is controllable, so that when working, by controlling the driving member 100 to rotate forward or reverse by the same angle, it can be ensured that the delivery angle of the object carrier 300 to deliver the target items to both sides is within a controllable range, ensuring that the delivery mechanism 10 can smoothly deliver the target items to the turnover container on either side. In addition, it also simplifies the control procedure of the delivery mechanism 10 delivering the target items to the turnover containers on both sides, thereby improving the delivery efficiency of the delivery mechanism 10.

[0134] Based on the above, it can be known that the first preset relationship can be that the difference between the first tilt angle and the second tilt angle is less than or equal to 10°. For example, the difference between the first tilt angle and the second tilt angle can be a suitable value of 5°, 7° or 10°.

[0135] For another example, the difference between the first inclination angle and the second inclination angle is 0°. In other words, when the second connecting member 230 is rotated to an angle symmetrical with respect to the first surface Q, the inclination angle of the bearing surface 310 is symmetrical with respect to the first surface Q.

[0136] Taking the case where the object carrier 300 is arranged parallel to the second connecting member 230 as an example, when the first angle is 75°, the first tilt angle is 75°, that is, the carrying surface 310 is flipped 75° from the horizontal position to the first position. In other words, the first delivery angle of the object carrier 300 in the first position is 75°. When the second angle is 75°, the second tilt angle is 75°, that is, the carrying surface 310 is flipped 75° from the horizontal position to the second position. In other words, the second delivery angle of the object carrier 300 in the second position is 75°.

[0137] In this way, when the second connecting member 230 rotates upward or downward at the same angle, the first delivery angle and the second delivery angle of the object carrier 300 can be ensured to be the same, so that when working, the object carrier 300 can deliver the target object to both sides at the same angle by controlling the driving member 100 to rotate forward or reverse at the same angle, thereby ensuring the consistency of the landing point of the delivery mechanism 10 to both sides. In addition, the control procedure of the delivery mechanism 10 delivering the target object to the turnover containers on both sides is simplified, thereby improving the delivery efficiency of the delivery mechanism 10.

[0138] In some examples, the transmission assembly 200 may be designed as follows, so that when the rotation angle of the second connecting member 230 is symmetrical with respect to the first plane Q, the first delivery angle and the second delivery angle have a first preset relationship, such as being equal. Figure 8 The projection lengths on the midplane T) are the same, and when the second connecting member 230 is perpendicular to the first surface Q, that is, when the second connecting member 230 is on the vertical plane T, the projections of the first connecting member 220, the second connecting member 230 and the fourth connecting member 250 on the first surface Q form a right triangle, and the first connecting member 220 is the hypotenuse.

[0139] Reference Figure 5 As shown, it should be noted that the connection position between the first connecting member 220 and the fixing member 210 is the first connecting position 210a, the connection position between the third connecting member 240 and the fixing member 210 is the second connecting position 210b, and the fourth connecting member 250 is the portion between the first connecting position 210a and the second connecting position 210b in the fixing member 210. For example, the portion between the extension line S1 of the first connecting position 210a in the horizontal direction and the extension line S2 of the second connecting position 210b in the horizontal direction can serve as the fourth connecting member 250.

[0140] It is understandable that in the embodiment of the present application, the second connecting member 230 will not rotate to the vertical plane T, and the above is only an example of the vertical plane T to illustrate the structural size relationship.

[0141] For example, the projection length of the fourth connecting member 250 on the vertical plane T is 180 mm, the length of the third connecting member 240 is 180 mm, the length of the first connecting member 220 is 100 mm, the length of the second connecting member 230 is 80 mm, and the projection of the fourth connecting member 250 on the first surface Q is 60 mm. In this way, when the second connecting member 230 is on the vertical plane T, the projections of the first connecting member 220, the second connecting member 230 and the fourth connecting member 250 on the first surface Q form a right triangle, and the first connecting member 220 is the hypotenuse.

[0142] The above arrangement allows the second connecting member 230 to be rotated upward or downward by the same angle relative to the first surface Q, thereby ensuring that the delivery angle of the object carrier 300 is the same when the rotation angle of the second connecting member 230 is the same.

[0143] It can be understood that the sizes of the above-mentioned connecting parts are only examples. In practical applications, the sizes of the above-mentioned connecting parts can be designed according to actual needs.

[0144] It should be noted that the extension length and projection length of the above-mentioned connecting parts all refer to the length or projection length of the part between the connection points (the points connected to other structural parts) of each connecting part. Taking the second connecting part 230 as an example, the length of the second connecting part 230 refers to the length of the part of the second connecting part 230 located between the first hinge point (e.g., point C) and the second hinge point (e.g., point D), or the projection length of the second connecting part 230 on the first surface Q refers to the projection length of the part of the second connecting part 230 located between the first hinge point (e.g., point C) and the second hinge point (e.g., point D) on the first surface Q.

[0145] Exemplarily, when the connection point of each connector is located at the end of each connector, the length of each connector is the actual length of each connector, and the projection length of each connector on the first surface Q is the projection length of the entire connector on the first surface Q.

[0146] Reference Figure 8 and Fig. 9 As shown, in some examples, when the second connecting member 230 is in the first position, the height of the bearing surface 310 from the working platform where the delivery mechanism 10 is located is a first height, and when the second connecting member 230 is in the second position, the height of the bearing surface 310 from the working platform is a second height; the first height and the second height have a second preset relationship.

[0147] The working platform where the delivery mechanism 10 is located may be the ground.

[0148] It should be noted that the height of the bearing surface 310 from the ground can be the height of any point on the bearing surface 310 from the ground. The height of the center point P of the bearing surface 310 from the ground is taken as an example for description below.

[0149] It is understandable that, because the target object is located on the carrying surface 310, the height of the carrying surface 310 from the ground determines the delivery height of the target object. Thus, when the heights of the carrying surface 310 from the ground are the same, the delivery heights of the target object are the same. For example, when the carrying surface 310 is rotated to the first position by the second connecting member 230, the first height from the ground is the delivery height of the target object, and when the carrying surface 310 is rotated to the second position by the second connecting member 230, the second height from the ground is the delivery height of the target object,

[0150] Among them, when the first height and the second height have a second preset relationship, the first delivery height and the second delivery height have a second preset relationship. For example, the second preset relationship can be that the difference between the first height and the second height is less than or equal to 10 mm, so that when the second connecting member 230 rotates upward or downward at the same angle, it can ensure that the difference between the first delivery height and the second delivery height of the carrier 300 is controllable, so that when working, by controlling the driving member 100 to rotate forward or reverse by the same angle, it can ensure that the delivery height of the target items delivered by the carrier 300 to both sides is within a controllable range, ensuring that the delivery mechanism 10 can smoothly deliver the target items to the turnover container on either side, and can also avoid interference between the carrier 300 and the turnover containers on both sides.

[0151] In some examples, the second preset relationship may be that the difference between the first height and the second height is a suitable value such as 3 mm, 5 mm, 8 mm, or 10 mm.

[0152] For example, the second preset relationship may be that the difference between the first height and the second height is 0 mm, that is, the sum of the first height and the second height is equal to each other, so that the first delivery height is equal to the second delivery height, thereby improving the consistency of the delivery point of the delivery mechanism 10 to the target objects on both sides.

[0153] In addition, when the second connecting member 230 is rotated to a symmetrical angle, the height of the carrying surface 310 is the same, ensuring that the delivery height of the target items is the same, and the distance between the carrier 300 and the turnover containers on both sides can be kept consistent, reducing the risk of interference between the carrier 300 and the turnover containers.

[0154] In some examples, the first height may be equal to the first delivery height, and the second height may be equal to the second delivery height. For example, when the target object starts to fall from the center P of the carrying surface 310, the first delivery height is equal to the first height, and the second delivery height is equal to the second height.

[0155] Of course, in other examples, the first height may be greater than or less than the first delivery height, and the second height may be greater than or less than the second delivery height. For example, when the target object falls from above the center P of the carrying surface 310, the first height is less than the first delivery height, and the second height is less than the second delivery height. Alternatively, when the target object falls from below the center P of the carrying surface 310, the first height is greater than the first delivery height, and the second height is greater than the second delivery height.

[0156] In some examples, the object carrier 300 can be slidably mounted on the second connecting member 230. For example, a slide groove can be provided on the second connecting member 230, and a slider can be provided on the mounting member 400 connected to the object carrier 300. The mounting member 400 can slide along the slide groove through the slider. When the second connecting member 230 rotates from the horizontal position to the first position, the object carrier 300 can slide downward along the second connecting member 230, so that the object carrier 300 is at a first height from the ground. When the second connecting member 230 rotates from the horizontal position to the second position, the object carrier 300 can slide upward along the second connecting member 230, so that the object carrier 300 is at a second height from the ground, ensuring that the first height and the second height are equal, thereby ensuring that the delivery height of the target item is equal.

[0157] For example, a driving motor may be provided on the transmission assembly 200 , such as the fixing member 210 , and the driving motor may drive the object carrier 300 to slide on the second connecting member 230 .

[0158] In some other examples, the third connection position 320 between the carrier 300 and the second connector 230 is offset relative to the center P of the carrier 300, and the third connection position 320 is offset toward the third end C of the second connector 230, that is, when the carrying surface 310 of the carrier 300 is toward the first side, the third connection position 320 is located above the center P of the carrier 300, and when the carrying surface 310 of the carrier 300 is toward the second side, the third connection position 320 is located below the center P of the carrier 300.

[0159] Among them, the third connecting position 320 is the position of the carrier 300 for connecting with the second connecting member 230, and the third connecting position 320 deviates from the center P of the carrier 300 and is biased toward the third end C of the second connecting position 210b. In this way, when the second connecting member 230 rotates to the first position above the first surface Q, the portion of the carrier 300 located below the third connecting position 320 is larger, and when the second connecting member 230 rotates to the second position below the first surface Q, the portion of the carrier 300 located below the third connecting position 320 is smaller, thereby ensuring that the first height and the second height are consistent, and further ensuring that the delivery height of the target item is consistent when the carrier 300 is rotated to both sides.

[0160] In addition, by offsetting the object carrier 300 on the second connecting member 230, the structural setting of the delivery mechanism 10 is simplified, the production cost of the delivery mechanism 10 is improved, and the component setting is simplified, ensuring that the transmission assembly 200 moves smoothly on the fixing member 210 without interference from other structures.

[0161] Exemplarily, the distance between the third connection position 320 and the center P of the object carrier 300 may be equal to half the length of the second connection member 230. For example, if the length of the second connection member 230 is 80 mm, the offset distance of the third connection position 320, i.e., the distance between the third connection position 320 and the center P of the object carrier 300 may be 40 mm.

[0162] Reference Figure 4 and Figure 7 As shown, the object carrier 300 may be a bowl-shaped structure, a flat plate structure or a rectangular structure, etc. The embodiment of the present application does not limit the structure of the object carrier 300, as long as it is ensured that when the object carrier 300 is at an angle other than the delivery angle, the target item can be stably carried on the object carrier 300 without accidentally falling, and at the delivery angle, the target item can be smoothly dropped into the turnover container.

[0163] It should be noted that different delivery angles and delivery heights can be designed for target items of different weights or carriers 300 of different shapes, so that when the carrier 300 is flipped to the second state or the third state, the target items on the carrier 300 can be smoothly delivered to the corresponding turnover container without interfering with the turnover container or the shelves of the seeding wall 2.

[0164] For example, when the carrier 300 is a flat plate structure, and the length of the carrier 300 is 500 mm and the thickness is 160 mm, when the carrying surface 310 of the carrier 300 is facing the first side, and the inclination angle relative to the first surface Q is 75° and 0°, the rightmost end of the carrier 300 is basically located on the same vertical plane T, then the inclination angle of the carrier 300 is 75 degrees, that is, the delivery angle is 105°, and when the carrier 300 is in the delivery angle position, that is, the first position, it will not interfere with the turnover container on the first side, that is, the right side.

[0165] Similarly, when the carrying surface 310 of the carrier 300 is facing the second side and the inclination angle relative to the first surface Q is 75° and 0°, the leftmost end of the carrier 300 is basically located on the same vertical plane T, then the inclination angle of the carrier 300 is 75 degrees, that is, the delivery angle is 75°, and when the carrier 300 is in the delivery angle position, that is, the second position, it will not cause interference to the turnover container on the second side, that is, the left side.

It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
