[0036] 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 infrastructures 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. In the existing technology, the connecting rod and the sorting module are rotationally matched through a connecting pin, and a bearing is correspondingly arranged on each sorting module to be rotationally matched with the connecting pin, so as 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.

[0037] The present utility model provides a sorting device, which can reduce the production cost of the sorting device.

[0038] 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 fixing plate 100, multiple sorting modules 200, and a connecting rod structure 300; the fixing plate 100 is arranged on the frame: multiple sorting modules 200 are arranged at intervals on the fixing plate 100. The sorting module 200 includes a mounting seat 210 and a mounting bracket 220. The mounting seat 210 is fixedly arranged on the fixing plate 100, the mounting bracket 220 is rotatably connected to the mounting seat 210, and a first connection hole 221a is arranged on the mounting bracket 220; the connecting rod structure 300 includes a rod body 310 and multiple connecting pins 320. Multiple second connection holes 311 are arranged on the rod body 310, and multiple connecting pins 320 are arranged in the multiple second connection holes 311; the connecting pin 320 passes through the first connection hole 221a and is in clearance fit with the first connection hole 221a.

[0039] Specifically, the frame is a supporting component of the sorting device, which is made of metal material. The fixing plate 100 is installed on the frame (not shown in the figure), and multiple sorting modules 200 are installed on the fixing plate 100 at intervals. The sorting module 200 includes a mounting seat 210 installed on the fixing plate 100 and a mounting bracket 220 rotatably connected to the mounting seat 210, so as to realize the rotation of the sorting module 200, and further control the sliding direction of the articles passing through it. Components such as a roller group and a transmission device are provided on the mounting bracket 220 (not shown in the figure). Power is transmitted to the roller group through the transmission device, and the goods are conveyed through the rotation of the roller group.

[0040] Please refer to Figure 3 and Figure 8 , for facilitating the synchronous rotation of multiple sorting modules 200 and reducing the number of motors used to drive the sorting module 200 to turn, therefore, the sorting device is also provided with a connecting rod structure 300. A first connection hole 221a is provided on the mounting bracket 220, and a plurality of second connection holes 311 are formed on the connecting rod structure 300. The plurality of second connection holes 311 correspond to the first connection hole 221a one by one, and a connection pin 320 is provided in each second connection hole 311. The connection pin 320 can be welded in the second connection hole 311, or can be arranged in the second connection hole 311 by screwing or clamping, or can be directly passed through the second connection hole 311, and no specific limitation is made on this. The connection pin 320 provided in the second connection hole 311 passes through the first connection hole 221a and is in clearance fit with the first connection hole 221a, so that multiple sorting modules 200 are connected together by the connecting rod structure 300, facilitating the synchronous rotation of multiple sorting modules 200.

[0041] Please refer to Figures 2 to 4 , it should be noted that the connection pin 320 and the first connection hole 221a are in clearance fit, and there is a certain gap between the two, so that the connection pin 320 can rotate relative to the first connection hole 221a. Furthermore, when the connecting rod structure 300 moves, it can drive a whole row of multiple sorting modules 200 to rotate synchronously. In this embodiment, since the connection pin 320 of the connecting rod structure 300 is directly in clearance fit with the first connection hole 221a, and no additional bearing structure is required between the two to achieve relative rotation, the use of bearing structures is reduced. That is to say, at least one bearing structure is reduced in use on each sorting module 200, 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.

[0042] The technical solution of the present utility model, the sorting device includes a frame, a fixing plate 100, a plurality of sorting modules 200 and a connecting rod structure 300; the fixing plate 100 is arranged on the frame: the plurality of sorting modules 200 are arranged on the fixing plate 100 at intervals, the sorting module 200 includes a mounting base 210 and a mounting bracket 220, the mounting base 210 is fixedly arranged on the fixing plate 100, the mounting bracket 220 is rotatably connected to the mounting base 210, and a first connection hole 221a is arranged on the mounting bracket 220; the connecting rod structure 300 includes a rod body 310 and a plurality of connecting pins 320, the rod body 310 is provided with a plurality of second connection holes 311, and the plurality of connecting pins 320 are arranged in the plurality of second connection holes 311; the connecting pin 320 passes through the first connection hole 221a and is in clearance fit with the first connection hole 221a. Thus, by directly using the connecting pin 320 of the connecting rod structure 300 to be in clearance fit with the first connection hole 221a, no additional bearing structure is required between the two to achieve relative rotation, reducing the use of bearing structures. That is to say, at least one bearing structure is reduced in use on each sorting module 200, 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.

[0043] Please refer to Figure 3 , in an embodiment, one end of the connecting pin 320 is provided with a limiting portion 322, the other end of the connecting pin 320 is provided with a jack 321a, the limiting portion 322 is used for abutting against the lower surface of the rod body 310, and the jack 321a is formed by penetrating the side wall of the connecting pin 320; the connecting pin 320 sequentially passes through the second connection hole 311 and the first connection hole 221a; the sorting device further includes a limiting member 400, and the limiting member 400 is inserted into the jack 321a; an elastic member 500 is sleeved on the connecting pin 320, one end of the elastic member 500 abuts against the mounting bracket 220, and the other end abuts against the limiting member 400.

[0044] Specifically, the connecting pin 320 includes a main body portion 321 and a limiting portion 322, the limiting portion 322 is arranged at the end of the main body portion 321, the main body portion 321 is arranged in a cylindrical shape, the limiting portion 322 is arranged in a circular disc shape, and a jack 321a is opened at one end of the main body portion 321 far from the limiting portion 322. When the connecting pin 320 realizes the clearance fit with the first connection hole 221a, it sequentially passes through the second connection hole 311 and the first connection hole 221a, and the limiting portion 322 is used for abutting against the lower surface of the rod body 310, and a limiting member 400 is inserted into the jack 321a to prevent the connecting pin 320 from coming out of the first connection hole 221a and the second connection hole 311.

[0045] Further, an elastic member 500 is sleeved on the connecting pin 320. One end of the elastic member 500 abuts against the mounting bracket 220, and the other end abuts against the limiting member 400, so as to provide an upward acting force for the connecting pin 320 to ensure that the connecting pin 320 passing through the second connecting hole 311 and the first connecting hole 221a will not fall down. 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.

[0046] It should be noted that in this embodiment, the connecting pin 320 connects the connecting rod structure 300 and the sorting module 200 by sequentially passing through the second connecting hole 311 and the first connecting hole 221a. 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.

[0047] Please refer to Figure 3 , furthermore, since the first connecting hole 221a is formed in the mounting bracket 220, and the mounting bracket 220 is usually thin in thickness, the height of the hole wall of the first connecting hole 221a is short. During the movement of the connecting rod structure 300 driving the sorting module 200 to rotate, the contact area between the connecting pin 320 and the first connecting hole 221a is small, which easily causes the sorting module 200 to swing up and down during rotation, affecting the rotation effect and also affecting the service life of the mounting bracket 220. Therefore, to solve the above problems, the sorting device further includes a connecting sleeve 600. The connecting sleeve 600 is disposed in the first connecting hole 221a, and the connecting sleeve 600 has a mating hole 610 for the connecting pin 320 to pass through. The connecting pin 320 is rotationally matched with the connecting sleeve 600, and the connecting pin 320 and the mating hole 610 are in clearance fit. One end of the elastic member 500 abuts against the connecting sleeve 600, and the other end abuts against the limiting member 400.

[0048] Please refer to Figure 3 and Figure 5 , in an embodiment, the mounting bracket 220 includes a bottom plate 221 and two side plates 222 disposed on opposite sides of the bottom plate 221. The first connecting hole 221a is formed in the bottom plate 221, and the height of the connecting sleeve 600 is not less than three times the thickness of the bottom plate 221. Such a setting can further ensure that when the connecting rod structure 300 drives the sorting module 200 to rotate, the contact area between the connecting pin 320 and the connecting sleeve 600 is large enough to prevent the sorting module 200 from swinging up and down during rotation and affecting the rotation effect.

[0049] In an embodiment, the distance between the outer wall surface of the connecting pin 320 and the hole wall of the mating hole 610 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 610 is too large, when the link structure 300 drives the sorting module 200 to rotate, the sorting module 200 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 610 is too small, it will affect the rotation effect of the sorting module 200, that is, when the link structure 300 drives the sorting module 200 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 610 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.

[0050] Please refer to Figure 6 and Figure 7 , in an embodiment, the sorting device includes multiple rows of sorting modules 200. Any row of sorting modules 200 includes a plurality of sorting modules 200, and the plurality of sorting modules 200 in any row are arranged at equal intervals; the plurality of sorting modules 200 in any row are connected by a link structure 300; the two link structures 300 connecting any two adjacent rows of sorting modules 200 are connected by a connecting plate 700, and a driving connection hole 330 is formed in one of the link structures 300; the sorting device further includes a driving device 800, and the power output side of the driving device 800 is connected to the driving connection hole 330 through a transmission member.

[0051] Specifically, the sorting device includes multiple rows of sorting modules 200. Among them, multiple sorting modules 200 in each row are connected together through a connecting rod structure 300, so as to realize the synchronous rotation of the sorting modules 200 in a whole row. Two connecting rod structures 300 of any two adjacent rows of sorting modules 200 are connected through a connecting plate 700, and the power output side of the driving device 800 and the driving connection hole 330 are connected through a transmission member. That is to say, when the driving device 800 is working, it drives a connecting rod structure 300 connected to it to move. At this time, since this connecting rod structure 300 is connected to another adjacent connecting rod structure 300 through the connecting plate 700. Therefore, when the driving device 800 is working, one driving device 800 can drive two rows of sorting modules 200 to rotate synchronously. Compared with the solution in which each row of sorting modules 200 is driven to rotate by a driving device 800, the present application reduces the number of driving devices 800 and further reduces the production cost of the whole machine.

[0052] Please refer to Figure 9 and Figure 10 , in an embodiment, a limiting groove 710 is opened at one end of the connecting plate 700, the connecting rod structure 300 is arranged in the limiting groove 710, and the connecting rod structure 300 is connected to the connecting plate 700 by screws; and / or,

[0053] A counterbore 720 is opened at the other end of the connecting plate 700, the connecting rod structure 300 is arranged in the counterbore 720, and one side wall of the connecting rod structure 300 is in limiting abutment with the side wall of the counterbore 720, and the connecting rod structure 300 is connected to the connecting plate 700 by screws.

[0054] Specifically, the connecting plate 700 is a rectangular plate. At both ends along its length direction, a limiting groove 710 is opened at one end, the connecting rod structure 300 is arranged in the limiting groove 710, the width of the connecting rod structure 300 is adapted to the width of the limiting groove 710, that is, the connecting rod structure 300 is adaptively installed in the limiting groove 710, and both side walls of the limiting groove 710 play a role in limiting the connecting rod structure 300. At the same time, the limiting groove 710 also plays a role in positioning the connecting rod structure 300. The connecting rod structure 300 is connected to the connecting plate 700 by screws. To prevent the connecting rod structure 300 from rotating relative to the connecting plate 700 and to further improve the connection stability between the connecting plate 700 and the connecting rod structure 300, at least two screws are used.

[0055] Similarly, a counterbore 720 is formed at the other end of the connecting plate 700. The link structure 300 is disposed within the counterbore 720. The width of the link structure 300 is adapted to the width of the counterbore 720, that is, the link structure 300 is adaptively installed within the counterbore 720. The side walls of the counterbore 720 play a role in limiting the link structure 300. At the same time, the counterbore 720 also plays a role in positioning the link structure 300. The link structure 300 is connected to the connecting plate 700 by screws. To prevent the link structure 300 from rotating relative to the connecting plate 700 and to further improve the connection stability between the connecting plate 700 and the link structure 300, at least two screws are used.

[0056] It should be noted that the connecting plate 700 may only have a limiting groove 710 formed at one end thereof. The link structure 300 is installed within the limiting groove 710, and the limiting groove 710 plays a role in limiting and positioning the link structure 300. The other end of the connecting plate 700 is directly connected to another link structure 300 by screws; or, the connecting plate 700 may only have a counterbore 720 formed at one end thereof. The link structure 300 is installed within the counterbore 720, and the counterbore 720 plays a role in limiting and positioning the link structure 300. The other end of the connecting plate 700 is directly connected to another link structure 300 by screws; or, limiting grooves 710 and counterbores 720 may be formed at both ends of the connecting plate 700 respectively. The limiting groove 710 plays a role in limiting and positioning one link structure 300, and the counterbore 720 plays a role in limiting and positioning another link structure 300.

[0057] Please refer to Figure 2 、 Figure 7 and Figure 9 In an embodiment, the drive connection hole 330 is located in the middle of the rod body 310. Specifically, the drive connection hole 330 is a connection hole for driving connection with the drive device 800. By disposing the drive connection hole 330 in the middle of the rod body 310, when the drive device 800 operates, it can drive the middle part of the rod body 310 to move, better balance the load of the drive device 800, and ensure the service life of the motor. It should be noted that the middle part of the rod body 310 refers to the middle part area of the rod body 310. For example, if the rod body 310 is evenly divided into five equal parts along its length direction, the middle part refers to the 2-4 equal part area of the rod body 310. If the rod body 310 is evenly divided into six equal parts along its length direction, the middle part refers to the 2-5 equal part area of the rod body 310.

[0058] Please refer to Figure 9, in an embodiment, the extending direction of the connecting rod structure 300 connected to the connecting plate 700 and the extending direction of the connecting plate 700 are perpendicular to each other, and the two connecting rod structures 300 respectively connected to both ends of the connecting plate 700 are parallel. That is, the adjacent two connecting rod structures 300 connected by the connecting plate 700 are parallel to each other, and the connecting plate 700 is perpendicular to the two connecting rod structures 300 respectively. In this way, when the driving device 800 drives the connecting rod structure 300 to move, the transmission effect of the force driving the connecting rod structure 300 to move can be ensured, and at the same time, the stability of the connecting rod structure 300 driving the sorting module 200 to rotate can also be ensured.

[0059] Please refer to Figure 8 , in an embodiment, a convex portion 312 is formed by the side wall of the rod body 310 corresponding to the position where the second connection hole 311 is provided bulging outward. Since the rod body 310 has a certain length, and the side wall corresponding to the position where the second connection hole 311 is provided bulges outward to form the convex portion 312.
