DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] The terms "first", "second", and "third" in the present invention are used to distinguish different objects rather than to describe a specific order. In addition, the terms "include", "have", and any variations thereof are intended to cover non-exclusive inclusions.

[0027] See also Figures 1 to 3 , a logistics sorting device provided in an embodiment of the present application is used to sort goods with labels. The logistics sorting device includes a main rail 200, a transport trolley 300, a read-write unit and an industrial control device. A plurality of sorting addresses are arranged along the extension direction of the main rail 200. The read-write unit is used to read the information of the label on each of the goods. The information includes the delivery address of the goods, and each of the delivery addresses is provided with the sorting address corresponding thereto. The transport trolley 300 can move along the main rail 200 to transport the goods to the sorting address corresponding thereto. When the goods pass through the read-write unit, the label on the goods can be quickly and automatically identified, without the need for manual scanning operations, thereby improving the scanning efficiency. At the same time, the industrial control device is respectively connected to the read-write unit and the transport cart 300 for communication. When the goods are transported to the corresponding sorting address, the transport cart 300 is controlled to sort the goods thereon to the corresponding sorting address, thereby realizing automated sorting. The logistics sorting equipment provided in the present application can be applied to the sorting of various goods, thereby effectively improving the applicability and sorting efficiency of the logistics sorting equipment.

[0028] Specifically, the label includes an optical label, such as a barcode or a QR code. The optical label is disposed at one end of the goods, illustratively, such as being attached to one end of the goods, so that the optical label can be read by the read-write unit. Accordingly, the read-write unit is a scanner.

[0029] It should be noted that the inventors consider that the delivery addresses of each cargo are different in the logistics sorting operation, so it is necessary to arrange multiple cargo collection devices in the moving direction of the carrier device 300 to collect multiple cargoes corresponding to the same delivery address. For example, multiple cargoes need to be delivered to different destinations, such as destination 1, destination 2, destination 3, etc. The label on each cargo records the destination information of the cargo. For example, cargo A needs to be delivered to destination 1 and cargo B needs to be delivered to destination 2. In the logistics sorting device, multiple sorting chutes 800 can be defined as destination 1, destination 2, destination 3, etc.

[0030] Specifically, the cargo includes but is not limited to rod-shaped members, and further description is given below by taking rod-shaped members as an example.

[0031] See also Figures 3 to 5 In the embodiment of the present application, the transport trolley 300 includes a silo 310 and a first bracket 320. Specifically, two silos 310 are symmetrically fixed on the first bracket 320. Of course, the embodiment of the present application does not limit the specific number of silos 310. In other embodiments of the present application, the number of silos 310 can also be 1, 3, 4, 5, 8, etc.

[0032] Further, the silo 310 includes a material barrel 311 and a support plate 312. The support plate 312 is configured to carry the goods to be sorted. Specifically, the material barrel 311 is provided with a storage cavity (not shown in the figure), and an inlet 3111 and an outlet 3112 that are interconnected with the storage cavity.

[0033] Furthermore, the material barrel 311 is a hollow columnar member, which is conducive to loading rod-shaped or columnar goods in the material barrel 311. Since the traditional sorting equipment is limited by the width of the conveyor belt, the length of the goods it is suitable for sorting is generally not more than 400mm. In the present application, since the material barrel 311 is a hollow columnar structure, it can be used for goods with a length greater than 400mm, solving the technical problem that the traditional sorting equipment is difficult to sort goods with a longer length.

[0034] Furthermore, a support plate 312 is disposed at the outlet 3112 .

[0035] Furthermore, the support plate 312 is movably connected to the material barrel 311 to open or close the discharge channel to achieve the sorting operation of the goods. It should be noted that the form of the movably connected between the support plate 312 and the material barrel 311 can be a sliding connection or a rotating connection. The support plate 312 and the material barrel 311 can be directly connected, or the support plate 312 and the material barrel 311 can be indirectly connected through a connecting piece, which is not limited here. Those skilled in the art should be able to understand that the discharge channel is also the path that the goods pass through when they fall into the sorting address through the outlet 3112.

[0036] In some embodiments of the present application, the support plate 312 is rotatably connected to the material barrel 311 to open or close the outlet 3112. Specifically, the support plate 312 has a closed position and an open position. Figure 1 , Figure 1 A schematic structural diagram of an embodiment of the logistics sorting equipment provided in the embodiment of the present application. Figure 1 The structure diagrams show that the support plate 312 is located in the open position and the closed position respectively.

[0037] When the support plate 312 is in the open position, the material discharge channel is also opened to allow the goods to fall from the material barrel 311 into the corresponding sorting address.

[0038] Furthermore, in order to enable the reading and writing unit to still scan the optical label on the goods when the goods are in the material barrel 311 , the material barrel 311 is provided with a light-transmitting area at a position corresponding to the label.

[0039] Furthermore, the silo 310 also includes a column 313. Figure 4 and Figure 5 , one end of the column 313 near the outlet 3112 is fixedly connected to the material barrel 311, and the other end of the column 313 extends in a direction away from the inlet 3111 and is rotatably connected to the support plate 312. In this way, the support plate 312 and the outlet 3112 are spaced apart and form an open area, and the open area forms a light-transmitting area. When the rod-shaped member is inserted into the material barrel 311, the optical label is located in the open area between the support plate 312 and the outlet 3112, so that after the goods are loaded into the material barrel 311, the read-write unit 100 can still scan the optical label on the goods.

[0040] In some embodiments of the present application, the silo 310 further includes an opening and closing device. The opening and closing device is connected to the material barrel 311 and the tray 312, and controls the opening or closing of the tray 312. When the opening and closing device controls the tray 312 to open, that is, controls the tray 312 to switch from a closed position to an open position, at which time the goods automatically fall from the material barrel 311 into the corresponding sorting address. After the goods in the material barrel 311 are automatically sorted, the opening and closing device controls the tray 312 to close, that is, controls the tray 312 to switch from an open position to a closed position. During the sorting and transportation process, the tray 312 is automatically opened or closed, which is conducive to improving the loading speed of the goods and thus improving the sorting efficiency of the logistics sorting equipment.

[0041] In an exemplary embodiment, the opening and closing device includes a slider-link mechanism 700. The support plate 312 cooperates with the slider-link mechanism 700. The connecting rod 720 is rotatably connected to the support plate 312, and the slider 710 is slidably connected to the material barrel 311. The slider 710 slides up and down to drive the support plate 312 to switch between the open position and the closed position.

[0042] The support plate 312 includes a first sub-support plate 3121 and a second sub-support plate 3122. The slider-connecting rod mechanism 700 includes a positioning column 730. The positioning column 730 is fixedly connected to the outer surface of the material barrel 311 and is arranged parallel to the length direction of the material barrel 311. The first sub-support plate 3121 has a first end (not marked in the figure) and a second end (not marked in the figure). The second sub-support plate 3122 has a third end (not marked in the figure) and a fourth end (not marked in the figure). The first end is rotatably connected to the column 313, and the second end is rotatably connected to the slider-connecting rod mechanism 700. The third end is rotatably connected to the column 313, and the fourth end is rotatably connected to the slider-connecting rod mechanism 700.

[0043] Specifically, the connecting rod 720 includes a first sub-connecting rod 721 and a second sub-connecting rod 722. One end of the first sub-connecting rod 721 is rotatably connected to the second end of the first sub-supporting plate 3121, and the other end of the first sub-connecting rod 721 is rotatably connected to the slider 710. One end of the second sub-connecting rod 722 is rotatably connected to the fourth end of the second sub-supporting plate 3122, and the other end of the second sub-connecting rod 722 is rotatably connected to the slider 710. The slider 710 is sleeved on the positioning column 730 and can slide up and down along the positioning column 730. An inclined wedge 711 is provided on the outer surface of the slider 710, and the inclined wedge 711 is used to cooperate with the groove 3152 (detailed description is given below). The process of the slider 710 sliding downward along the positioning column 730 is the process of the first sub-supporting plate 3121 and the second sub-supporting plate 3122 opening the discharge channel. Accordingly, the process of the slider 710 sliding upward along the positioning column 730 is the process of the first sub-supporting plate 3121 and the second sub-supporting plate 3122 closing the discharge channel. The technical solution of using the slider-connecting rod mechanism 700 in conjunction with the first sub-supporting plate 3121 and the second sub-supporting plate 3122 is conducive to reducing the rotation space required when the supporting plate 312 is converted from the closed position to the open position, thereby helping to reduce the occupied space of the logistics sorting equipment.

[0044] Furthermore, the opening and closing device also includes a second guide wheel 3123, and the second guide wheel 3123 is rotatably connected to the slider 710, and the second guide wheel 3123 is used to realize the conversion of the support plate 312 from the open position to the closed position (detailed description is given below).

[0045] In another exemplary embodiment, please continue to refer to Figure 4 and Figure 5 The opening and closing device includes a slider-linking rod mechanism 700 and a buckle rod 315. The specific structure and function of the slider-linking rod mechanism 700 are described above and will not be repeated here. Figure 5 As shown, the buckle rod 315 can be a strip plate or a rod-shaped part. One end of the buckle rod 315 is provided with a groove 3152, and the other end of the buckle rod 315 is rotatably connected to the material barrel 311. When the first sub-supporting plate 3121 and the second sub-supporting plate 3122 are in the closed position, the inclined wedge 711 is located in the groove 3152.

[0046] Furthermore, the opening and closing device further includes a spring 318, and the spring 318 is used to reset the buckle rod 315. The buckle rod 315 is provided with a pressure rod (not marked in the figure) near the rotation connection between the buckle rod 315 and the material barrel 311, and the pressure rod is perpendicular to the axis direction of the buckle rod 315. Of course, the pressure rod can also be fixedly arranged on the outer surface of the material barrel 311; or, the buckle rod 315 and the material barrel 311 are both provided with pressure rods, which is not specifically limited here.

[0047] Specifically, the spring 318 is a compression spring. The compression spring is sleeved on the pressure rod, one end of the compression spring abuts against the material barrel 311, and the other end of the compression spring abuts against the buckle rod 315. On the one hand, when the support plate 312 is in the closed position, the buckle rod 315 is subjected to the elastic force applied by the compression spring, so that the groove 3152 tightly clamps the inclined wedge 711, thereby preventing the goods loaded inside the material barrel 311 from falling during the movement. On the other hand, when the support plate 312 is converted from the open position to the closed position, the compression spring applies a thrust to one end of the buckle rod 315. When the slider 710 squeezes the buckle rod 315, the end of the buckle rod 315 close to the slider 710 generates a tension under the action of the compression spring, and the buckle rod 315 can automatically reset under the action of the tension to lock the inclined wedge 711, so that the support plate 312 is in the closed position.

[0048] For further information, see Figure 2 and Figure 3 The end of the buckle rod 315 close to the inclined wedge 711 is provided with a guide surface 3151, and the guide surface 3151 is designed as an inclined surface. When the support plate 312 is converted from the open position to the closed position, the inclined wedge 711 can slide along the guide surface 3151, and at the same time, the inclined wedge 711 continuously presses the guide surface 3151 to rotate the buckle rod 315. When the support plate 312 is in the closed position, the buckle rod 315 rotates in the opposite direction to the initial position under the action of the compression spring, so that the groove 3152 clamps the inclined wedge 711.

[0049] When the silo 310 moves along the cargo conveying direction, the buckling rod 315 rotates to separate the inclined wedge 711 from the groove 3152 (described in detail below). The slider 710 moves downward along the positioning column 730 under the action of gravity, thereby driving the first sub-supporting plate 3121 and the second sub-supporting plate 3122 to switch from the closed position to the open position, the discharge channel is opened, and the cargo immediately falls from the material barrel 311 into the corresponding sorting address.

[0050] Of course, in some other embodiments of the present application, the first sub-supporting plate 3121 and the second sub-supporting plate 3122 can also be replaced by a supporting plate 312, and the supporting plate 312 is rotatably connected to the material barrel 311. Specifically, one end of the supporting plate 312 is directly rotatably connected to the material barrel 311; or the supporting plate 312 is rotatably connected to the material barrel 311 through the column 313. The specific connection method of the supporting plate 312, the column 313 and the material barrel 311 can be referred to above, and will not be repeated here. The opening and closing device includes a buckle rod 315. The specific structure and installation relationship of the buckle rod 315 can be referred to above, and will not be repeated here. When the supporting plate 312 is in the closed position, the end of the supporting plate 312 that is not connected to the column 313 is at least partially located in the groove 3152. When the supporting plate 312 is in the open position, the supporting plate 312 is separated from the groove 3152. The technical solution of this embodiment omits the slider-connecting rod mechanism 700, thereby simplifying the structure of the silo 310 and helping to reduce costs.

[0051] See also Figure 6 and Figure 7 In some embodiments of the present application, the industrial control device includes a first switch; the first switch controls the opening and closing device to open the support plate 312, that is, controls the support plate 312 to switch from the closed position to the open position.

[0052] In one embodiment of the present application, the first switch 500 includes a power member, a second bracket 530 and a trigger member. The trigger member has a trigger position and a non-trigger position. Figure 7 Specifically, the trigger member is an opening plate 520. When the opening plate 520 is located at the trigger position, one end face of the opening plate 520 is inclined toward the moving direction of the goods to form a guiding slope. The power member is installed on the second bracket 530. The power member drives the opening plate 520 to move to the trigger position when the goods are sorted to the corresponding sorting address. When the transport trolley 300 is located at the preset position, the power member controls the trigger member to switch from the non-trigger position to the trigger position, and the transport trolley 300 controls the support plate 312 to switch from the closed position to the open position when the trigger member is located at the trigger position. Among them, the preset position can be set adjacent to the corresponding sorting address, and is located in front of the corresponding sorting address along the conveying direction of the goods.

[0053] As another exemplary embodiment, the opening plate 520 triggers the locking rod 315 to rotate when it is in the trigger position so that the wedge 711 is separated from the groove 3152. Specifically, the power member includes an electromagnetic assembly 510. The electromagnetic assembly 510 includes an electromagnet 511, a push rod 512, a rotating rod 513 and a first elastic member 514. The opening plate 520 is rotatably connected to the second bracket 530. The second bracket 530 can be installed on the main guide rail 200. The opening plate 520 includes a first plate 521 and a second plate 522. The guiding inclined surface is an end surface of the second plate 522. The rotating rod 513 is connected to the push rod 512, and the central axis of the rotating rod 513 is perpendicular to the central axis of the push rod 512. The first elastic member 514 is a compression spring. The compression spring is mounted on the push rod 512. The electromagnet 511 controls the push rod 512 to move along the F direction.

[0054] When the goods loaded on the transport cart 300 need to fall into the corresponding sorting address, the industrial control device sends a signal to the first switch 500 at the position corresponding to the sorting address. After the electromagnet 511 receives the signal from the industrial control device, the electromagnet 511 controls the push rod 512 to move along the F direction, the compression spring is compressed, the first plate 521 rotates clockwise and further drives the second plate 522 to move to the trigger position. Subsequently, when the material barrel 311 continues to move closer to the first switch 500, the second plate 522 will abut against the buckle rod 315, that is, the guide slope will abut against the buckle rod 315. As the material barrel 311 continues to move forward, the guide slope will continuously squeeze the buckle rod 315, and the spring 318 will be continuously compressed, thereby causing the buckle rod 315 to rotate. As the locking rod 315 rotates to a certain angle, the inclined wedge 711 separates from the groove 3152, and the support plate 312 rotates downward under the action of its own gravity and the gravity of the slider 710, so that the support plate 312 opens the discharge channel, and the goods immediately fall from the material barrel 311 into the corresponding sorting address.

[0055] Furthermore, if the goods loaded in the subsequent adjacent material barrel 311 do not need to be sorted into the sorting address, the industrial control device sends a signal to the first switch 500 at the position corresponding to the sorting address. After the electromagnet 511 receives the signal from the industrial control device, the electromagnet 511 stops working, and the push rod 512 moves in the opposite direction of the F direction under the action of the compression spring, and the second plate 522 then moves away from the trigger position and moves to the non-trigger position. Therefore, the buckle rod 315 in the subsequent material barrel 311 will not rotate the wedge 711 to separate from the groove 3152 due to being squeezed, and the goods will not fall from the material barrel 311.

[0056] Furthermore, each sorting address is provided with a first switch 500. When the transport trolley 300 needs to sort the loaded goods to the sorting address, the first switch 500 at the sorting address starts to work to move the second plate 522 to the trigger position, so that the logistics sorting equipment can automatically unload the goods, which saves labor costs and effectively improves the sorting efficiency of the logistics sorting equipment.

[0057] In some embodiments of this application, please refer to Figure 5 In order to facilitate the process of the guide bevel surface triggering the inclined wedge 711 to leave the groove 3152, the first switch 500 further includes a first guide wheel 317. The first guide wheel 317 is rotatably connected to the end of the buckle rod 315 away from the groove 3152. The first guide wheel 317 can roll along the guide bevel surface to trigger the buckle rod 315 to rotate so that the inclined wedge 711 is separated from the groove 3152. The existence of the first guide wheel 317 effectively avoids excessive wear of the buckle rod 315 due to the sliding friction directly generated between the guide bevel surface and the buckle rod 315.

[0058] See also Fig.10 and Fig.11 In another embodiment of the present application, the industrial control device includes a second switch 600. The second switch 600 includes a first planar guide rail 610 and a second planar guide rail 620. The end surfaces of the first planar guide rail 610 and the second planar guide rail 620 are planar structures. The first planar guide rail 610 is installed on the second sub-auxiliary guide rail 420. The second planar guide rail 620 is installed on the third sub-auxiliary guide rail 430. Along the moving direction of the silo 310, the heights of the first planar guide rail 610 and the second planar guide rail 620 from the ground gradually increase. The first planar guide rail 610 and the second planar guide rail 620 are both provided with a guide plane (that is, the end surface of the plane). Along the moving direction of the silo 310, the second guide wheel 3123 moves along the guide planes of the first planar guide rail 610 and the second planar guide rail 620, so that the slider 710 slides upward along the positioning column and the support plate 312 rotates from the open position to the closed position, for example, continuously rotates from the initial vertical state until it finally becomes a horizontal state so that the support plate 312 is converted from the open position to the closed position.

[0059] Further, the second guide wheel 3123 is rotatably connected to the slider 710. The second guide wheel 3123 can roll along the first planar guide rail 610 and / or the second planar guide rail 620 to trigger the slider 710 to slide upward to drive the support plate 312 to switch from the open position to the closed position. The second guide wheel 3123 is provided on the slider 710. On the one hand, it can make the process of switching the support plate 312 from the open position to the closed position smoother, and on the other hand, it can also reduce the friction loss between the slider 710 and the first planar guide rail 610 and / or the second planar guide rail 620, and increase the service life of both.

[0060] In some other embodiments of the present application, when the first sub-tray plate 3121 and the second sub-tray plate 3122 are replaced by a tray plate 312, and the tray plate 312 is rotatably connected to the material barrel 311 (this embodiment has been described in detail above and will not be repeated here), the second guide wheel 3123 is rotatably connected to the bottom surface of the tray plate 312. The second switch 600 includes a first guide rail and a second guide rail, and the first guide rail and the second guide rail have the same structure and both include a curved surface with a preset torsion angle. Specifically, the torsion angle of the curved surface is 90 degrees, that is, the curved surface has a first end and a second end that are relatively arranged, and the angle between the plane where the first end is located and the plane where the second end is located is 90 degrees. The first guide rail and / or the second guide rail trigger the rotation of the tray plate 312 to convert the tray plate 312 from an open position to a closed position. Exemplarily, the first guide rail and the second guide rail are symmetrically arranged. One end of the first guide rail is connected to one end of the second guide rail. The heights of the first guide rail and the second guide rail from the ground gradually increase along the moving direction of the transport trolley 300. The second guide wheel 3123 rolls along the curved surfaces of the first guide rail and the second guide rail to rotate the support plate 312 from the open position to the closed position, for example, continuously rotating from the initial vertical state until it finally becomes a horizontal state so that the support plate 312 is switched from the open position to the closed position.

[0061] Specifically, after the silo 310 is unloaded, the support plate 312 is in the open position. When the transport trolley 300 continues to move forward to the first guide rail and the second guide rail, the second guide wheel 3123 begins to roll along the curved surface, and the curved surface begins to squeeze the support plate 312. As the transport trolley 300 continues to move forward, the curved surface continues to squeeze the support plate 312 to rotate it, thereby converting the support plate 312 from the open position to the closed position. The entire conversion process is automatically completed as the transport trolley 300 moves, without the need for manual intervention, which not only saves labor costs but also improves the sorting efficiency of the logistics sorting equipment.

[0062] In some embodiments of the present application, the logistics sorting equipment further includes a sorting chute 800. Figure 1 , Figure 8 and Fig. 9 The sorting address is provided with a chute assembly 810 and a collector 820. The goods dropped from the transport trolley 300 pass through the chute assembly 810 and then fall into the collector 820.

[0063] The slide assembly 810 includes a first slide 811 and a second slide 812 that can be flipped, and a power member that drives the first slide 811 or the second slide 812 to move. Specifically, the power member includes a first motor 830 and a second motor 840; the first slide 811 and the second slide 812 have the same structure, and the first slide 811 and the second slide 812 are both rotatably mounted on a bracket (not marked in the figure). The first slide 811 and the second slide 812 are both box-type structures with an open end 8111. The first slide 811 and the second slide 812 include a plurality of door panels 850, and the specific number of the door panels 850 is two. The two door panels 850 are rotatably connected to the body of the first slide 811 in a split-opening manner to form one side thereof. The slide assembly also includes a second slider-connecting rod mechanism 860. The second slider-connecting rod mechanism 860 is connected to the second motor 840 and the door panel 850. The second motor 840 drives the slider to slide, and the slider drives the connecting rod to move and further drives the door panel 850 to rotate.

[0064] The first slide 811 and the second slide 812 both have a first position and a second position. Specifically, the first position is the position when the first slide 811 or the second slide 812 is in a vertical state and the opening 8111 is upward. The goods dropped from the transport trolley 300 enter the first slide 811 and / or the second slide 812 through the opening 8111. The second position is the position where the first slide 811 or the second slide 812 is in a horizontal state. The first motor 830 drives the first slide 811 or the second slide 812 to switch between the first position and the second position.

[0065] When the first slide 811 or the second slide 812 is in the first position, the door panel 850 is closed, and the goods can fall from the transport trolley 300 into the first slide 811 or the second slide 812. When the first slide 811 or the second slide 812 is in the second position, the second motor 840 drives the door panel 850 to open, and the goods fall horizontally into the collector 820. The goods are sorted horizontally into the collector 820, so that the goods are no longer placed in a messy state inside the collector 820, but are roughly parallel to the width or length direction of the collector 820, so that the storage space inside the collector 820 can be effectively used.

[0066] In some other embodiments of the present application, the chute body 810 is a liftable chute, that is, the height of the chute body 810 is adjustable to improve its applicability. Specifically, the chute body 810 includes a first sub-chute, a second sub-chute and a third sub-chute. The outlet of the first sub-chute is rotatably connected to the inlet of the second sub-chute, and the outlet of the second sub-chute is rotatably connected to the inlet of the third sub-chute. The bottom plate of the third sub-chute can be opened and closed, and the third sub-chute is horizontally arranged directly above the collector 820. When the goods fall from the transport trolley 300 into the entrance of the first sub-chute, they pass through the second sub-chute and the third sub-chute in turn. After the goods slide into the third sub-chute, their placement state changes from a vertical rotation state to a horizontal state. Subsequently, the bottom plate of the third sub-chute is opened, and the goods fall horizontally into the interior of the collector 820.

[0067] Please continue reading Figure 1 In some embodiments of the present application, the main guide rail 200 is supported in mid-air by a bracket. Of course, in other embodiments of the present application, the main guide rail 200 is suspended from the ceiling. This is helpful to avoid the logistics sorting equipment from occupying too much site area. Exemplarily, the main guide rail 200 is arranged in a closed loop, so that the transport trolley can move in a circle along the main guide rail 200. The main guide rail 200 can be arranged in a ring in the plane dimension, and can also be arranged in a ring in the space dimension. The main guide rail 200 adopts a ring arrangement scheme in the space dimension, which is more conducive to improving the utilization rate of the site space.

[0068] A rotating first chain (not shown in the figure) is provided inside the main rail 200. The hook 321 hangs the transport trolley on the first chain, and the first chain drives the transport trolley 300 to move along the main rail 200. The rotation speed of the first chain is controllable and adjustable. When the number of goods to be sorted by the logistics sorting device is large, the speed of the first chain can be increased while the number of the transport trolleys 300 remains unchanged, thereby improving the sorting efficiency of the logistics sorting device; on the other hand, since the hanging method is conducive to the flexible adjustment of the number of transport trolleys 300 in the logistics sorting device, the staff can adjust the number of transport trolleys 300 in the logistics sorting device according to the actual situation in actual operation to adjust the sorting efficiency of the logistics sorting device. For example, when the number of goods is relatively large, the sorting efficiency of the logistics sorting device can be improved by increasing the number of transport trolleys 300 without changing the rotation speed of the first chain.

[0069] For further information, see Figure 6 and Fig.10 , the logistics sorting equipment also includes an auxiliary guide rail 400; the auxiliary guide rail 400 includes a first sub-auxiliary guide rail 410, and the plurality of material barrels 311 are rotatably connected to guide wheels 314; the first sub-auxiliary guide rail 410 is arranged between two rows of material barrels 311, and the plurality of guide wheels 314 roll along the first sub-auxiliary guide rail 410. The additional first sub-auxiliary guide rail 410 in the logistics sorting equipment can effectively prevent the transport cart 300 from shaking during movement or unloading. On the other hand, guide wheels 314 are provided in two rows of mutually symmetrical material barrels 311, and the guide wheels 314 roll along the first sub-auxiliary guide rail 410 during the movement of the transport cart 300, so that the transport cart 300 has less resistance when moving.

[0070] Furthermore, the auxiliary rail 400 also includes a second sub-auxiliary rail 420 and a third sub-auxiliary rail 430. The third sub-auxiliary rail 430 is arranged opposite to the second sub-auxiliary rail 420, and the first sub-auxiliary rail 410 is located between the second sub-auxiliary rail 420 and the third sub-auxiliary rail 430. In this way, on the one hand, it is beneficial to reduce the weight of the main rail 200, and on the other hand, it is beneficial to perform a separate, all-round scan of each row of transport carts 300. When the second sub-auxiliary rail 420 and the third sub-auxiliary rail 430 are arranged in the logistics sorting equipment, a plurality of the scanning guns are installed on the first sub-auxiliary rail 410 and the second sub-auxiliary rail 420 to form a first sub-scanning area 110. A plurality of the scanning guns are installed on the second sub-auxiliary rail 420 and the third sub-auxiliary rail 430 to form a second sub-scanning area (not shown in the figure).

[0071] Specifically, the number of the scanning guns is 12, and the 12 scanning guns are evenly divided into a first scanning gun group and a second scanning gun group. The number of scanning guns corresponding to each light-transmitting area or label placement area is 6. For example, in the first scanning gun group, 3 scanning guns are installed on the second sub-auxiliary guide rail 420, and the other 3 scanning guns are installed on the first sub-auxiliary guide rail 410. The scanning direction of the scanning gun installed on the second sub-auxiliary guide rail 420 is opposite to the scanning direction of the scanning gun installed on the first sub-auxiliary guide rail 410, so as to form a 360-degree scanning area in the first sub-scanning area. Similarly, in the second scanning gun group, 3 scanning guns are installed on the first sub-auxiliary guide rail 410, and the other 3 scanning guns are installed on the fourth 430 rail. The scanning direction of the scanning gun installed on the first sub-auxiliary guide rail 410 is opposite to the scanning direction of the scanning gun installed on the third sub-auxiliary guide rail 430, so as to form a 360-degree scanning area in the second sub-scanning area. Since the 360-degree scanning area can fully cover the light-transmitting area or the label placement area, no matter at what angle the goods to be sorted are loaded into the material barrel 311, when the transport cart 300 moves the goods through the first sub-scanning area 110 or the second sub-scanning area, the labels can be quickly and automatically identified. When loading goods into the material barrel 311, there is no need to place an optical label, and there is no need to adjust the direction or angle of the goods or the read-write unit in the subsequent process, which reduces labor intensity and improves labor efficiency.

[0072] Of course, the number of the scanners can also be 4. The specific installation positions of the scanners are not described here, as long as the first sub-scanning area 110 or the second sub-scanning area can cover the optical label placed in the label placement area, and the specific number of the scanners is not limited here.

[0073] The logistics sorting equipment provided by the embodiment of the present application has the following working process: the goods are put into the silo 310 at the loading platform. Then the first chain drives the transport trolley 300 to run along the track (i.e. the main rail 200), and when passing through the scanning area, the read-write unit 100 automatically reads the label on the goods. When the transport trolley 300 loaded with goods is about to pass through the corresponding sorting address, the first switch 500 starts to work, the guide slope of the trigger member extends to the trigger position, triggering the opening and closing device to rotate, and the support plate 312 is converted from the closed position to the open position due to gravity, and the goods fall freely and fall into the sorting chute 800 below. After the goods pass through the chute body 810, the first slide 811 and / or the second slide 812 rotate from the first position (vertical state) to the second position (horizontal state). Then the goods fall horizontally into the container 820 below the chute body 810 to complete the sorting. The transport trolley 300 continues to move and passes the second switch 600. The second guide wheel 3123 rolls on the first planar guide rail 610 and / or the second planar guide rail 620. The slider is squeezed and slides upward, and at the same time drives the support plate 312 to rotate through the connecting rod 720. When the inclined wedge 711 slides into the groove 3152, the support plate 312 is switched from the open position to the closed position, and the first chain drives the transport trolley 300 to return to the loading platform for the next round of cargo loading.
