[0034] In logistics transportation, it is necessary to sort the items sent to different regions in a warehouse or a transfer center. Therefore, an automated sorting system has become one of the necessary infrastructure facilities in a warehouse or a transfer center. The existing sorting device sorts items by the rotation of multiple sorting modules. Among them, multiple sorting modules are connected by connecting rods, so as to drive a row of sorting modules to rotate synchronously, and then control the sliding direction of the items passing through them to complete the sorting of the items. The existing connecting rod and sorting module are rotatably connected together by a connecting pin, and a bearing is correspondingly arranged on each sorting module to rotatably cooperate with the connecting pin to realize the rotation of the sorting module. However, the setting of the bearing further increases the production cost of the sorting device, and the assembly efficiency of the connecting rod and the sorting module is also relatively low.

[0035] The present utility model provides a sorting device, which can reduce the production cost of the sorting device.

[0036] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, the sorting device includes a frame (not shown in the figure), a plurality of sorting modules 100, a driving assembly 200, and a connecting rod 300; the plurality of sorting modules 100 are arranged at intervals on the frame, and the plurality of sorting modules 100 are arranged in a straight line, and the plurality of sorting modules 100 are all rotatably connected to the frame; the sorting module 100 includes a mounting frame 110 and a rotating seat 120, the mounting frame 110 is provided with a first rotating hole 111a, the rotating seat 120 is rotatable relative to the frame, and the rotating seat 120 is fixedly connected to the mounting frame 110; the driving assembly 200 includes a driving motor 210 and a driving gear 220, the driving gear 220 is connected to the motor shaft of the driving motor 210, and the driving gear 220 is in transmission connection with the rotating seat 120 of at least one of the plurality of sorting modules 100 to drive the sorting module 100 to rotate; the connecting rod 300 includes a rod body 310 and a plurality of connecting pins 320, the rod body 310 is provided with a plurality of second rotating holes 311, one second rotating hole 311 corresponds to one first rotating hole 111a, and the plurality of connecting pins 320 are arranged in the plurality of second rotating holes 311; the connecting pin 320 passes through the first rotating hole 111a and is in clearance fit with the first rotating hole 111a.

[0037] Specifically, the frame is a supporting component of the sorting device, and the plurality of sorting modules 100 are arranged at intervals on the frame, and the plurality of sorting modules 100 are arranged in a straight line. It can be understood that the plurality of sorting modules 100 are arranged in rows, and in the sorting device, multiple rows of sorting modules 100 can be provided. The plurality of sorting modules 100 are all rotatably connected to the frame. Here, the rotational connection can be directly connected to the frame or indirectly connected to the frame through other structures. The plurality of sorting modules 100 are rotatable relative to the frame, thereby controlling the sliding direction of the articles passing through them. The mounting frame 110 is provided with components such as a roller group and a transmission device (not shown in the figure), and power is transmitted to the roller group through the transmission device, and the goods are conveyed by the rotation of the roller group.

[0038] The sorting module 100 includes a mounting frame 110 for installing a roller set, a transmission assembly for transmitting power to the roller set, and other structures. A rotating seat 120 is further provided below the mounting frame 110. The rotating seat 120 is rotatable relative to the machine frame, and the rotating seat 120 is fixedly connected to the mounting frame 110 to ensure that when the rotating seat 120 is driven to rotate, the mounting frame 110 can be driven to rotate together, thereby driving the entire sorting module 100 to rotate. When the driving motor 210 operates, it drives the driving gear 220 to rotate, and the driving gear 220 is in transmission connection with the rotating seat 120 of at least one of the multiple sorting modules 100 to drive the sorting module 100 to rotate, so as to realize the control of the goods conveying direction by the rotation of the sorting module 100.

[0039] Please refer to Figures 3 to 5 、 Figure 7 and Figure 8 For the convenience of the multiple sorting modules 100 to rotate synchronously and reduce the number of motors used for driving the sorting modules 100 to turn, therefore, the sorting device is further provided with a connecting rod 300. A first rotating hole 111a is provided on the mounting frame 110 of the sorting module 100. A plurality of second rotating holes 311 are formed on the connecting rod 300. The plurality of second rotating holes 311 correspond to the first rotating hole 111a one by one, and a connecting pin 320 is arranged in each second rotating hole 311. The connecting pin 320 can be welded in the second rotating hole 311, or can be arranged in the second rotating hole 311 by screwing or clamping, or can be directly passed through the second rotating hole 311, and no specific limitation is made thereto. The connecting pin 320 arranged in the second rotating hole 311 passes through the first rotating hole 111a and is in clearance fit with the first rotating hole 111a, so that the multiple sorting modules 100 are connected together by the connecting rod 300, which is convenient for the synchronous rotation of the multiple sorting modules 100.

[0040] Please refer to Figure 5 It should be noted that the connecting pin 320 is in clearance fit with the first rotating hole 111a, and there is a certain gap between the two, so that the connecting pin 320 can rotate relative to the first rotating hole 111a. Furthermore, when the connecting rod 300 moves, it can drive a whole row of multiple sorting modules 100 to rotate synchronously. In this embodiment, since the connecting pin 320 of the connecting rod 300 is directly in clearance fit with the first rotating hole 111a, and no additional bearing structure is required between the two to realize relative rotation, the use of the bearing structure is reduced. That is to say, at least one bearing structure is reduced in each sorting module 100, thereby reducing the production cost of the whole sorting device. At the same time, one process of installing the bearing structure is also saved, improving the production efficiency.

[0041] The technical solution of the present utility model adopts the connecting pin 320 of the connecting rod 300 to directly fit with the first rotating hole 111a in a clearance manner, and no additional bearing structure is required between the two to achieve relative rotation, thereby reducing the use of bearing structures. In other words, the use of at least one bearing structure is reduced on each sorting module 100, thereby reducing the production cost of the entire sorting device. At the same time, it also saves a process of installing the bearing structure, thereby improving production efficiency.

[0042] See also Figure 1 and Figure 2 In one embodiment, a fixed plate 400 is provided on the frame, a fixed seat (not shown in the figure) is provided on the fixed plate 400, the fixed seat and the rotating seat 120 are rotationally matched, and the driving assembly 200 is transmission-connected to the rotating seat 120.

[0043] Specifically, a fixed plate 400 is provided on the frame, a fixed seat is fixedly provided on the fixed plate 400, and a rotating seat 120 is rotatably mounted on the fixed seat. The rotating seat 120 is rotatably connected to the fixed seat, and the rotating seat 120 is fixedly connected to the mounting frame 110 to ensure that when the rotating seat 120 is driven to rotate, the mounting frame 110 can be driven to rotate together, thereby driving the sorting module 100 to rotate as a whole. Alternatively, in other embodiments, it can also be understood that the rotating seat 120 includes a fixed part (not marked in the figure) and a rotating part, wherein the fixed part is fixedly mounted together with the fixed plate 400, and the rotating part is fixedly connected together with the mounting frame 110, and when the rotating part is driven to rotate, the mounting frame 110 can be driven to rotate together, thereby driving the sorting module 100 to rotate as a whole.

[0044] See also Figure 2Furthermore, the rotating seat 120 has an external gear 121, and the driving motor 210 and the driving gear 220 are respectively arranged on opposite sides of the fixed plate 400, and the driving gear 220 and the external gear 121 are meshed. Specifically, when the driving motor 210 is working, it drives the driving gear 220 to rotate, and the driving gear 220 and the external gear 121 are meshed, thereby driving the rotating seat 120 to rotate, and then driving the mounting frame 110 fixedly connected to the rotating seat 120 to rotate, so as to realize the control of the conveying direction of the goods by the sorting module 100 through rotation. It should be noted that, since the external gear 121 is mainly used to mesh with the driving gear 220, and the number of the driving motor 210 and the driving gear 220 is set to one, the rotation of multiple sorting modules 110 can be realized, that is, among the multiple sorting modules 100, only one is connected to the driving assembly 200 in a transmission manner, and the other sorting modules 100 are connected together through a sorting module 100 connected to the driving assembly 200 by the connecting rod 300, and then when the sorting module 100 rotates, it drives the other sorting modules 100 to rotate together. Therefore, the external gear 121 can be set only on one sorting module 100 meshing with the driving gear 220, and the rotating seats 120 of other sorting modules may not be provided with external gears 121.

[0045] See also Figure 5 In one embodiment, a limiting portion 322 is provided at one end of the connecting pin 320, and a socket 321a is provided at the other end of the connecting pin 320. The limiting portion 322 is used to abut against the lower surface of the rod body 310, and the socket 321a is formed by the side wall of the connecting pin 320; the connecting pin 320 is sequentially penetrated by the second rotating hole 311 and the first rotating hole 111a; the sorting device also includes a limiting member 500, which is inserted into the socket 321a; the connecting pin 320 is sleeved with an elastic member 600, one end of the elastic member 600 abuts against the mounting frame 110, and the other end abuts against the limiting member 500.

[0046] Specifically, the connecting pin 320 includes a main body and a limiting portion 322, wherein the limiting portion 322 is arranged at the end of the main body, the main body is cylindrical, the limiting portion 322 is circular, and a plug hole 321a is provided at one end of the main body away from the limiting portion 322. When the connecting pin 320 realizes clearance fit with the first rotating hole 111a, it passes through the second rotating hole 311 and the first rotating hole 111a in sequence, and the limiting portion 322 is used to abut against the lower surface of the rod body 310, and a limiting member 500 is inserted into the plug hole 321a to prevent the connecting pin 320 from coming out of the first rotating hole 111a and the second rotating hole 311.

[0047] Please continue reading Figure 5, Further, an elastic member 600 is sleeved on the connecting pin 320. One end of the elastic member 600 abuts against the mounting bracket 110, and the other end abuts against the limiting member 500, so as to provide an upward acting force for the connecting pin 320 to ensure that the connecting pin 320 passing through the second rotation hole 311 and the first rotation hole 111a will not fall downward. At the same time, it also makes the limiting portion 322 abut against the lower surface of the rod body 310, and applies an upward acting force to the rod body 310 to prevent the relatively long rod body 310 from deflecting downward.

[0048] It should be noted that, in this embodiment, the connecting pin 320 connects the connecting rod 300 and the sorting module 100 by sequentially passing through the second rotation hole 311 and the first rotation hole 111a. The connecting pin 320 does not need to be connected to the rod body 310 by screwing, welding, clamping or other connection methods. The direct passing-through method is simple and convenient to operate, and can also apply an upward acting force to the rod body 310 to prevent the relatively long rod body 310 from deflecting downward.

[0049] Please refer to Figure 5 , Further still, since the first rotation hole 111a is formed in the mounting bracket 110, and the mounting bracket 110 is usually relatively thin, the height of the hole wall of the first rotation hole 111a is short. During the process of the connecting rod 300 moving to drive the sorting module 100 to rotate, the contact area between the connecting pin 320 and the first rotation hole 111a is small, which easily causes the sorting module 100 to swing up and down during rotation, affecting the rotation effect and also affecting the service life of the mounting bracket 110. Therefore, to solve the above problems, the sorting device further includes a connecting sleeve 700. The connecting sleeve 700 is disposed in the first rotation hole 111a, and the connecting sleeve 700 has a mating hole 710 for the connecting pin 320 to pass through. The connecting pin 320 is rotationally mated with the connecting sleeve 700, and the connecting pin 320 and the mating hole 710 are in clearance fit. One end of the elastic member 600 abuts against the connecting sleeve 700, and the other end abuts against the limiting member 500.

[0050] Please refer to Figure 2 and Figure 5 , In an embodiment, the mounting bracket 110 includes a bottom plate 111 and two side plates 112 disposed on opposite sides of the bottom plate 111. The first rotation hole 111a is formed in the bottom plate 111, and the height of the connecting sleeve 700 is not less than three times the thickness of the bottom plate 111. Such a setting can further ensure that when the connecting rod 300 drives the sorting module 100 to rotate, the contact area between the connecting pin 320 and the connecting sleeve 700 is large enough to prevent the sorting module 100 from swinging up and down during rotation and affecting the rotation effect.

[0051] In one embodiment, the distance between the outer wall surface of the connecting pin 320 and the hole wall of the mating hole 710 is 0.01 mm - 0.22 mm. Specifically, if the distance between the outer wall surface of the connecting pin 320 and the hole wall of the mating hole 710 is too large, when the connecting rod 300 drives the sorting module 100 to rotate, the sorting module 100 is likely to swing up and down during rotation, affecting the rotation effect; if the distance between the outer wall surface of the connecting pin 320 and the hole wall of the mating hole 710 is too small, it will affect the rotation effect of the sorting module 100, that is, when the connecting rod 300 drives the sorting module 100 to rotate, the rotation effect is poor. Therefore, the distance between the outer wall surface of the connecting pin 320 and the hole wall of the mating hole 710 is limited to between 0.01 mm and 0.22 mm. Exemplarily, the distance between the two can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.11 mm, 0.13 mm, 0.15 mm, 0.18 mm, 0.2 mm, 0.21 mm, 0.22 mm.

[0052] Please refer to Figure 3 、 Figures 6 to 8 , in one embodiment, the rod body 310 extends linearly, and a plurality of second rotation holes 311 are arranged at intervals on the rod body 310; or,

[0053] the rod body 310 includes at least one arc segment 312, the second rotation hole 311 is arranged at the end of the arc segment 312, and the inner edge of the arc segment 312 avoids the sorting module 100.

[0054] Specifically, the connecting rod 300 can adopt a straight connecting rod 300. The straight connecting rod 300 has a simple structure and is easy to manufacture, and does not occupy too much internal space of the sorting device; or, the connecting rod 300 can also adopt an arc-shaped connecting rod 300, that is, the rod body 310 includes at least one arc segment 312, and one arc segment 312 is arranged corresponding to one sorting module 100. The number of the arc segments 312 can be adjusted according to the number of sorting modules 100 in a row. By setting the connecting rod 300 to be arc-shaped and arranging the inner edge of the arc segment 312 to avoid the sorting module 100, the connecting rod 300 can drive the sorting module 100 to rotate by a large amplitude, thereby increasing the flexibility of the sorting device and further improving the usage scenarios of the sorting device.

[0055] In one embodiment, when the rod body 310 includes at least one arc segment 312, the rotation range of the sorting module 100 is from 0° to 180°. Specifically, at this time, the rod body 310 is of the structure of the arc connecting rod 300, that is, the connecting rod 300 does not include a portion extending in a straight line. The arc connecting rod 300 has a first position, a second position, and a third position. The second position is between the first position and the third position, and the rotation range when rotating from the second position to the first position or the third position is 90° each, so that the connecting rod 300 can drive the sorting module 100 to achieve a relatively large range of rotation, thereby increasing the flexibility of the sorting device, and further improving the usage scenarios of the sorting device.

[0056] Preferably, the arc segment 312 is in an arc shape. First of all, the arc-shaped connecting rod 300 helps to optimize the force transmission path, enabling the force to be transmitted to the target component more smoothly and efficiently; this optimization of force transmission helps to improve the overall efficiency and response speed of the mechanical system. Secondly, the design of the arc shape can absorb and reduce vibrations and noises generated during mechanical movement to a certain extent; this is because the arc-shaped structure has better damping characteristics, which can effectively disperse and weaken the propagation of vibrations and noises. Finally, the arc-shaped connecting rod 300 can enhance the stability of the overall structure, because the arc shape can provide better support and balance effects, reducing stress concentration and deformation of the structural components during movement. Of course, in other embodiments, the arc segment 312 can also be in an elliptical shape.

[0057] Please refer to Figure 6 and Figure 8 ., further, the arc segment 312 is arranged in an arc shape, and the radian of multiple arc segments 312 is the same, and any two adjacent arc segments 312 are in arc transition. Specifically, the radian of multiple arc segments 312 is the same, which simplifies the structure of the connecting rod 300, facilitates the processing of the connecting rod 300, and further reduces the production and manufacturing cost of the connecting rod 300. Any two adjacent arc segments 312 are in arc transition. It can be understood that the design of arc transition can enhance the overall structural strength of the connecting rod 300, because the arc structure can better resist bending and torsional forces, so it can increase the stability and reliability of the connecting rod 300 under complex working conditions; at the same time, the arc transition can disperse the stress generated during the operation of the connecting rod 300, reducing the phenomenon of stress concentration, thereby improving the durability and service life of the connecting rod 300.

[0058] Please refer to Figure 7 and Figure 8 ., in one embodiment, the connecting rod 300 is integrally formed. The processing method of integral setting is stable, reliable, and has strong stability, and the processing cost is relatively low, thereby increasing the structural strength and service life of the connecting rod 300 and reducing the production and manufacturing cost of the connecting rod 300.

[0059] The above are only exemplary embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
