DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] At present, the logistics and transportation industry is developing rapidly, and the amount of goods handled in the warehouses of various logistics companies has increased dramatically. In order to ease the pressure of cargo sorting and transportation and improve express delivery efficiency, some sorting equipment has been invested in the distribution center. However, the existing sorting equipment has low sorting efficiency and high operating and management costs.

[0026] In order to alleviate the above problems, researchers have developed a sorting device that improves sorting efficiency and reduces operating and management costs by using a sorting device and a container conveying device in combination. The specific implementation is as follows.

[0027] The present invention provides a sorting device, please refer to Figure 1 and Figure 2 The sorting equipment includes: a sorting device 10 and a container conveying device 20 arranged below the sorting device 10; the sorting device 10 includes a plurality of sorting stations 11 arranged along a predetermined path, and each sorting station 11 has a discharge port for outputting goods; a plurality of containers are placed on the container conveying device 20, and one or more of the plurality of containers can be aligned with the discharge port in rotation so as to receive the goods output from the discharge port through the container.

[0028] In the sorting equipment provided by the embodiment of the present invention, the goods on each sorting station are output through the discharge port and fall into the container below, and multiple containers are placed on the container conveying device, and the multiple containers can move under the driving action of the container conveying device or other power, so that the required container can be rotated to the bottom of the discharge port according to the sorting requirements of the goods, so as to receive the goods through the container; when another goods on the aforementioned sorting station is output from the discharge port, another required container is rotated to the bottom of the discharge port of the sorting station according to the sorting requirements of the goods, so as to receive the goods through another container; and so on, the goods on each sorting station are sorted through the above process. Therefore, through the mutual cooperation between the sorting station, the container conveying device and the multiple rotatable containers, the sorting efficiency of the goods is greatly improved, which helps to reduce the operation and management costs.

[0029] In order to improve the sorting efficiency, each sorting station 11 has two discharge ports, namely a first discharge port 111 and a second discharge port 112, and the first discharge port 111 and the second discharge port 112 are respectively arranged on both sides of the predetermined path; a plurality of containers are arranged along the connecting direction of the first discharge port 111 and the second discharge port 112. The two discharge ports can discharge materials at the same time, and the discharge efficiency is improved.

[0030] Please continue to refer to Figure 1 and Figure 2 An embodiment of the present invention provides a sorting device, which includes a sorting device 10 moving along a predetermined path and a container conveying device 20 located below the sorting device 10; the sorting device 10 includes a plurality of sorting stations 11, and the plurality of sorting stations 11 are arranged along the predetermined path, wherein each sorting station 11 is respectively provided with a first discharge port 111 and a second discharge port 112 on both sides of the predetermined path; a plurality of containers are placed on the container conveying device 20, and the plurality of containers are arranged in a linear array, and the direction of the linear array is the direction along the line connecting the first discharge port 111 and the second discharge port 112, and the plurality of containers on the container conveying device 20 can reciprocate in the direction connecting the first discharge port 111 and the second discharge port 112, so that two containers among the plurality of containers are aligned with the first discharge port 111 and the second discharge port 112. For example, a plurality of containers are placed at a position corresponding to each sorting station 11 on the container conveying device 20, and the plurality of containers placed at a position corresponding to each sorting station 11 on the container conveying device 20 can be controlled to reciprocate in the direction of the line connecting the two discharge ports of the corresponding sorting station, so that two containers among the plurality of containers can be aligned with the two discharge ports in rotation. In this way, goods can be delivered to a plurality of containers through each discharge port, increasing the number of containers that can be delivered by a sorting device, and enabling the sorting of a large number of goods at the same time.

[0031] The sorting equipment provided by the embodiment of the present invention, when the first discharge port discharges materials, the container corresponding to the goods of the first discharge port on the container conveying device moves to the position corresponding to the first discharge port to receive the goods from the first discharge port; when the second discharge port discharges materials, the container corresponding to the goods of the second discharge port on the container conveying device moves to the position corresponding to the second discharge port to receive the goods from the second discharge port; when the first discharge port and the second discharge port discharge materials at the same time, the two containers corresponding to the goods of the two discharge ports on the container conveying device move to the positions corresponding to the first discharge port and the second discharge port respectively to receive the goods of the corresponding discharge ports. By using the discharge port in conjunction with multiple containers, the sorting efficiency can be improved, which helps to reduce the operation and management costs.

[0032] Specifically, if Figure 1 and Figure 2 As shown, the sorting device 10 is used to sort and sort the received goods according to the preset classification rules, wherein the predetermined path is the path direction determined by the structural shape of the sorting device 10, such as an open straight line, a curve, or even a closed circle or a ring curve. The container conveying device 20 is located below the sorting device 10, and the containers on the container conveying device 20 can be used to collect and store the goods belonging to each list or each category.

[0033] The sorting device 10 sorts the goods belonging to the same list, such as an order, into one or more containers, with high sorting efficiency, and can solve the need for sorting massive goods according to the list. The sorting device is an open linear structure or a closed rotary cycle structure. Accordingly, the predetermined path can be an open linear path or a closed rotary cycle path. Specifically, the sorting device 10 can be an open linear or curved linear structure with a starting point and an end point, such as an L-type, U-type, or I-type structure. Of course, the sorting device 10 can also be a closed rotary cycle structure, that is, the starting point and the end point of the rotary cycle structure are the same point or connected together, so that the sorting device 10 is in a closed loop, such as a circular rotary cycle structure, a rectangular rotary cycle structure, or an irregularly shaped rotary cycle structure designed according to the equipment installation site. Further, when the sorting device 10 is a circular rotary cycle structure, a plurality of sorting stations are arranged along a circular rotary cycle. Compared with the open linear structure, the closed rotary circulation structure can realize the continuous circulation flow sorting of goods, maintain the continuous motion state and the cyclic re-sorting state. Compared with the open linear structure, it also has the function of dynamic caching of goods, avoids the parking of goods, improves the sorting efficiency, and saves more equipment installation space.

[0034] The following is a detailed description using the rotary circulation structure as an example. Specifically, a plurality of sorting stations 11 are distributed along the rotary circulation path of the sorting device 10. A first discharge port 111 and a second discharge port 112 are respectively arranged on both sides of the rotary circulation path of each sorting station 11. A plurality of containers are placed on the container conveying device 20, and the plurality of containers are arranged in a linear array, and the direction of the linear array is along the line connecting the first discharge port 111 and the second discharge port 112. The plurality of containers on the container conveying device 20 can reciprocate in the line connecting the first discharge port 111 and the second discharge port 112, so that two of the plurality of containers are aligned with the first discharge port 111 and the second discharge port 112. For example, eight container positions are arranged on the container conveying device 20, and the containers or container positions are numbered from one to eight in sequence. The container conveying device 20 can be driven by the movement of the container to align container one with the first discharge port 111, collect the goods sorted from the first discharge port 111, and control container three to align with the second discharge port 112, and collect the goods sorted from the second discharge port 112. Of course, in actual applications, any two containers among the multiple containers can be determined to be aligned with the first discharge port 111 and the second discharge port 112 according to the control strategy, and the present invention does not impose any restrictions on this, as long as the above sorting process can be achieved.

[0035] It should be noted that the above container has a certain cavity and an opening, which can be used to store goods. The container can be a box, a box or a bag product made of metal or non-metallic materials. For example: wooden boxes, woven bags, material racks, etc.

[0036] It has been described above how the two discharge ports of the sorting station on the sorting device cooperate with the container conveying device to achieve cargo sorting. Next, it will be described how the container conveying device moves the containers thereon so that multiple containers are aligned with the discharge ports on each sorting station in rotation, thereby receiving cargo from the two discharge ports.

[0037] The container conveying device 20 includes a plurality of container conveying mechanisms 21 arranged along a predetermined path, each container conveying mechanism 21 being located below a sorting station, wherein a plurality of containers are placed on each container conveying mechanism 21 .

[0038] In some embodiments, each container conveying mechanism 21 can drive multiple containers thereon to reciprocate along the line connecting the first discharge port 111 and the second discharge port 112, so that two containers among the multiple containers are respectively aligned with the first discharge port 111 and the second discharge port 112. That is, the container can reciprocate along the line connecting the first discharge port 111 and the second discharge port 112, and the reciprocating motion process can be automatically realized by the container conveying device 20.

[0039] In other embodiments, each container conveying mechanism 21 can reciprocate along the line connecting the first discharge port 111 and the second discharge port 112 under the action of external force, so that two containers among the multiple containers are aligned with the first discharge port 111 and the second discharge port 112 respectively.

[0040] In some embodiments, the container conveying device 20 further includes a rotary mechanism 22, on which a plurality of container conveying mechanisms 21 are arranged at intervals along the circumference of the rotary mechanism 22; the rotary mechanism 22 can drive the plurality of container conveying mechanisms 21 thereon and the plurality of containers placed on each container conveying mechanism 21 to perform rotary motion to achieve automatic container replacement. Specifically, a staff member, a workbench or an automatically replaced conveyor is provided at a fixed position outside the sorting device, and the rotary mechanism can rotate the container conveying mechanism carrying a full container to the fixed position to achieve the operation of replacing the container.

[0041] When the goods arrive at the sorting station 11 of the sorting device 10, as the sorting device 10 rotates, the sorting station 11 can move according to the sorting rules, and deliver the goods to the container on the corresponding container conveying device 20 through the first discharge port 111 or the second discharge port 112 of the sorting station 11. Therefore, by switching the position of the sorting station 11 and the container conveying device 20, the coordinated sorting between the two discharge ports on the sorting station 11 and the multiple containers can be achieved, which greatly improves the sorting efficiency of the goods.

[0042] Next, the structures of the container conveying mechanism 21 and the rotating mechanism 22 will be described in detail.

[0043] Please refer to Figure 3, the container conveying device 20 includes a container conveying mechanism 21 and a rotating mechanism 22; the container conveying mechanism 21 is fixedly connected to the rotating mechanism 22, a plurality of containers are placed on the container conveying mechanism, and the rotating mechanism can drive the container conveying mechanism to rotate. In some examples, the rotating path of the rotating mechanism 22 can be consistent with the rotating circulation path of the sorting device 10, that is, the rotating path of the rotating mechanism 22 and the rotating circulation path of the sorting device 10 can be in the same direction or in the opposite direction, or the rotating mechanism 22 and the sorting device 10 can also use the same power and the same speed. When the rotating mechanism 22 moves along the rotating circulation path under the sorting device 10, it drives the container conveying mechanism 21 to rotate. Since a plurality of containers are placed on the container conveying mechanism 21 and the plurality of containers are reciprocating, the plurality of containers can be aligned with the first discharge port 111 or the second discharge port 112 on the sorting station 11. In other embodiments, while the sorting station 11 of the sorting device 10 rotates, the container conveying device 20 can also rotate, which can reduce the time required for the sorting station 11 to align with the corresponding container and improve the sorting efficiency. At the same time, the rotation of the container conveying device 20 can also realize the circulation of the container, which helps to shorten the box change time during the sorting process. In other embodiments, while the sorting station 11 of the sorting device 10 rotates, the rotary mechanism 22 remains stationary, that is, the rotary mechanism 22 will not drive the container conveying device 20 to rotate. It can be understood that the above-mentioned container conveying mechanism 21 can be an automated conveying machine or a conveying trolley, which can be driven by mechanical power or by human power, and the embodiment of the present invention does not limit this.

[0044] Please refer to Figure 4 and Figure 5 The container conveying mechanism 21 includes a reciprocating conveying assembly 211 and a container carrying platform 212; a plurality of containers are placed on the container carrying platform 212, the reciprocating conveying assembly 211 is fixedly connected to the rotary mechanism 22, and the output end of the reciprocating conveying assembly is connected to the container carrying platform, and the container carrying platform 212 reciprocates linearly with the reciprocating conveying assembly 211. Specifically, the output end of the reciprocating conveying assembly 211 is connected to the container carrying platform 212, or the container carrying platform 212 is located above the reciprocating conveying assembly 211 and connected to the reciprocating conveying assembly 211. The reciprocating conveying assembly 211 can drive the container carrying platform 212 to reciprocate along the connecting direction of the first discharge port 111 and the second discharge port 112, so that the plurality of containers placed on the container carrying platform 212 are aligned with the first discharge port 111 and the second discharge port 112 in rotation.

[0045] In some embodiments, the container conveying mechanism 21 as a whole can be connected to the sorting device 10 or other fixed devices through a reciprocating conveying component, so that the container conveying mechanism 21 as a whole can make reciprocating motion, thereby driving the container to reciprocate; of course, the container conveying mechanism 21 itself can also drive the container to reciprocate through the reciprocating conveying component. For example, the container conveying mechanism 21 uses a belt or roller to drive the container to reciprocate through a belt or roller.

[0046] Specifically, if Figure 4 and Figure 5 As shown, the aforementioned container conveying mechanism 21 includes a reciprocating conveying assembly 211 and a container carrying platform 212. The reciprocating conveying assembly 211 has the ability to reciprocate linearly, and the container carrying platform 212 is installed together with the reciprocating conveying assembly 211. The reciprocating conveying assembly 211 provides the container carrying platform 212 with power for reciprocating motion, and the container placed on the container carrying platform 212 can reciprocate linearly, so as to align with the first discharge port 111 or the second discharge port 112 on the sorting station 11. At the same time, by means of the fixed connection between the reciprocating conveying assembly 211 and the rotating mechanism 22, the rotation of the rotating mechanism 22 can also drive the rotation of the reciprocating conveying assembly 211, that is, drive the rotation of the container carrying platform 212 and the container.

[0047] Optionally, a plurality of limiters are provided on one side of the container carrying platform 212 on which the plurality of containers are placed, and the limiters are used to limit the movement of the containers on the container carrying platform 212. The movement includes translation of the container in a first direction and / or a second direction, wherein the first direction is the movement direction of the container carrying platform 212, and the second direction is perpendicular to the first direction.

[0048] Specifically, in order to prevent the multiple containers from sliding due to external force or inertia when the container carrying platform 212 moves, a limiter can be set in the linear motion direction of the container carrying platform 212 to restrict the sliding of the containers in this direction. For example, a plurality of partitions 2121 can be set on the container carrying platform 212, that is, the container carrying platform 212 is as follows: Figure 5 The conveyor belt with partitions 2121 shown, or protrusions on one or both sides of the container carrying platform 212, is used to limit the movement of the container in the linear motion direction of the container carrying platform 212. The spacing between adjacent partitions or protrusions depends on the size of the container.

[0049] Optionally, limit members may be provided on both sides of a direction perpendicular to the linear motion direction of the container carrying platform 212, i.e., on both sides of a line connecting the first discharge port 111 and the second discharge port 112, to prevent the container from sliding sideways and tipping over, thereby ensuring the safety of the container structure.

[0050] In some embodiments, the rotating mechanism 22 includes a rotating chassis 221 and a plurality of rollers; Figure 6 , multiple container conveying mechanisms 21 are arranged on the side of the rotating chassis 221 away from the ground along the circumference of the rotating chassis 221, and multiple rollers are arranged on the side of the rotating chassis 221 close to the ground; the rotating chassis 221 can move on the ground through the rollers, so that the multiple container conveying mechanisms 21 on the rotating chassis 221 can make a rotational movement relative to the sorting device 10. Specifically, the rollers can be universal wheels, that is, the rotation mechanism 22 can include the rotating chassis 221 and the universal wheels 222; the container conveying mechanism 21 is fixed on the side of the rotating chassis 221 away from the ground, and the universal wheels 222 are fixed on the side of the rotating chassis 221 close to the ground.

[0051] Optionally, the aforementioned slewing mechanism may be a disc structure, including a rotating chassis 221 and a universal wheel 222. The container conveying mechanism 21 is fixed to the side of the rotating chassis 221 away from the ground, and the universal wheel 222 is fixed to the side of the rotating chassis 221 close to the ground. Thus, under the support of the universal wheel 222, as the universal wheel 222 rolls, the rotating chassis 221 can drive the container conveying mechanism 21 to rotate, facilitating the circulation and replacement of containers.

[0052] Furthermore, a plurality of universal wheels 222 are installed on the bottom surface of the rotating chassis 221. In this case, the rotating chassis 221 may not have a spindle. On the one hand, the universal wheels 222 can support the rotating chassis 221. On the other hand, as the universal wheels 222 roll, the rotating chassis 221 can rotate, thereby synchronously driving the plurality of container conveying mechanisms 21 thereon to rotate synchronously, so as to realize the circulation and replacement of the containers. Of course, the rollers can also be ordinary fixed wheels. In this case, in order to ensure that the rotating chassis 221 can rotate normally, a spindle needs to be set at its center position, and the plurality of fixed wheels are arranged along the tangent direction of the turntable. Thus, on the one hand, the fixed wheels can support the rotating chassis 221. On the other hand, due to the setting of the spindle, the rotating chassis 221 can also rotate, thereby synchronously driving the plurality of container conveying mechanisms 21 thereon to rotate synchronously, so as to realize the circulation and replacement of the containers.

[0053] In other embodiments, the rotating mechanism 22 includes a rotating chassis 221 and a base, and the rotating chassis 221 is rotatably arranged on the base; a plurality of container conveying mechanisms 21 are arranged on the side of the rotating chassis 221 away from the ground along the circumference of the rotating chassis 221, and the base is arranged on the side of the rotating chassis 221 close to the ground; the rotating chassis 221 can rotate relative to the base, so that the plurality of container conveying mechanisms 21 on the rotating chassis 221 can make a rotating motion relative to the sorting device 10.

[0054] In other embodiments, the rotating mechanism 22 includes a track adapted to a predetermined path; the bottom of the container conveying mechanism 21 is slidably connected to the track, so that a plurality of container conveying mechanisms 21 can move along the track.

[0055] Optionally, the rotary mechanism 22 includes a circular track; the bottom of the container conveying mechanism 21 is slidably connected to the circular track. Specifically, as another implementation scheme of the rotary mechanism 22, the aforementioned rotary mechanism 22 may include a circular track, which may be a circular track or multiple concentric circular tracks, and the circular track may be set on the ground. When the track is one circle, it may be set along the middle of the rotary path of the container conveying mechanism 21; when the track is two circles, it may be set in parallel along the inner and outer sides of the rotary path of the container conveying mechanism 21; when the track is multiple circles, it may be evenly or unevenly distributed and set in parallel between the inner and outer sides of the rotary path of the container conveying mechanism 21. The bottom of the container conveying mechanism 21 may be slidably connected to the circular track. Of course, in order to reduce resistance, rollers may also be used for rolling connection.

[0056] It should be noted that the present embodiment is not limited to the aforementioned roller being a universal wheel 222 or a fixed wheel or a circular track. As long as the rotary motion of the container conveying mechanism 21 can be achieved, the specific method is not limited.

[0057] It has been described above how the container conveying device moves the containers thereon to receive the goods from the two discharge ports. The following describes how the goods move on the sorting station.

[0058] In some embodiments of the present application, a conveying component is provided at the sorting station. Figure 7 Each sorting station 11 is provided with a sorting conveying component 113, which can move the goods toward the first discharge port 111 or the second discharge port 112 to convey the goods to the first discharge port or the second discharge port.

[0059] In some embodiments, Figure 7 As shown, the aforementioned sorting station 11 is provided with a sorting conveying component 113, which can move bidirectionally along the connecting direction of the first discharge port 111 and the second discharge port 112 under the control of the control system, thereby driving the goods to move in the direction of the first discharge port or the second discharge port. For example, when the sorting conveying component 113 moves toward the first discharge port 111, the goods on the sorting station 11 can be delivered from the first discharge port 111, and when the sorting conveying component 113 moves toward the second discharge port 112, the goods on the sorting station 11 can be delivered from the second discharge port 112. By using the bidirectionally movable sorting conveying component 113, a discharge port can be automatically selected to deliver the goods.

[0060] Specifically, the above-mentioned sorting and conveying components can be any one of the conveying components of a non-partition conveyor belt, a partition conveyor belt, a conveyor roller, a tilting tray, and a tilting bucket. When a partition conveyor belt is used, since the conveyor belt is provided with a partition structure, the movement caused by inertia when the rollable goods such as water bottles are conveyed to the discharge port can be avoided. When the sorting and conveying components are implemented as a non-partition conveyor belt, a partition conveyor belt or a conveying roller, the non-partition conveyor belt, the partition conveyor belt or the conveying roller can be rotated in the direction of the discharge ports on both sides so that the goods thereon can be delivered to the corresponding container via the first discharge port or the second discharge port. When the sorting and conveying components are implemented as a tilting tray or a tilting bucket, the tilting tray or the tilting bucket can be flipped and tilted in the direction of the first discharge port or the second discharge port so that the goods thereon can slide into the corresponding container via the first discharge port or the second discharge port. It can be understood that the conveying components of various structural forms expand the optional range of technicians and help to improve the practical application range of the equipment. In practical applications, technicians can flexibly select suitable conveying components according to actual structural requirements, and the embodiments of the present invention do not restrict this. For example, the above-mentioned sorting conveying component can also be any one of a high-pressure air blowing device, a mechanical lever, and a universal ball conveying platform.

[0061] Optionally, refer to Figure 7 , each sorting station 11 may be provided with a side baffle 114, which is located between the first discharge port 111 and the second discharge port 112 and is provided on both sides of the discharge direction. Specifically, each sorting station 11 is provided with two side baffles 114, and the two side baffles 114 are respectively located on both sides of the sorting station 11 along the predetermined path. Specifically, as Figure 7 As shown, in order to prevent the goods from accidentally slipping off the sorting station 11, side baffles 114 are provided on both sides along the discharging direction between the first discharging port 111 and the second discharging port 112. When the goods are placed on the sorting station 11, if they bounce to the edge of the sorting station 11, they can be restrained by the side baffles 114 on both sides to prevent them from falling.

[0062] In some embodiments, when the container is fully loaded, the container can be replaced by the first conveying mechanism.

[0063] In some embodiments, the sorting device further includes one or more first conveying mechanisms 31, one end of each first conveying mechanism 31 is aligned with one of the multiple container conveying mechanisms 21; each first conveying mechanism 31 can convey the container on it to the corresponding container conveying mechanism 21, and / or can receive the container from the corresponding container conveying mechanism 21. Here, the container conveying mechanism 21 corresponding to the first conveying mechanism 31 refers to the container conveying mechanism 21 currently aligned with the first conveying mechanism 31, and driven by the rotating mechanism 22, different container conveying mechanisms 21 can be rotated to a position aligned with the first conveying mechanism 31.

[0064] For example, the sorting device may also include a first conveying mechanism 31; the first conveying mechanism 31 is aligned with one of the multiple container conveying mechanisms 21, and the first conveying mechanism 31 can move in a direction close to or away from the container conveying mechanism 21, and is used to introduce a preset number of idle containers into the container conveying mechanism 21, and / or, to export the containers to be replaced from the container conveying mechanism 21.

[0065] In actual operation, the installation position of the first conveying mechanism 31 can be determined by the on-site assembly personnel according to the actual layout of the installation site, fixed at a certain position, and aligned with one of the multiple container conveying mechanisms 21. When the first conveying mechanism 31 moves in the direction close to the container conveying mechanism 21, a preset number of idle containers from the outside can be introduced into the container conveying mechanism 21 to realize the input and replenishment of idle containers; when the first conveying mechanism 31 moves in the direction away from the container conveying mechanism 21, the container to be replaced that has been filled with goods can be exported from the container conveying mechanism 21 to realize the output of fully loaded containers. Therefore, by controlling and changing the conveying direction of the first conveying mechanism 31, a set of components can be used to realize the import and export of containers, which is relatively space-saving.

[0066] Optionally, please refer to Figure 3 , the sorting device may further include a second conveying mechanism 32; the second conveying mechanism 32 is aligned with one of the multiple container conveying mechanisms 21, and the conveying direction of the second conveying mechanism 32 is opposite to the conveying direction of the first conveying mechanism 31. It should be understood that the second conveying mechanism 32 and the first conveying mechanism 31 are arranged at different positions, and the second conveying mechanism 32 and the first conveying mechanism 31 correspond to different container conveying mechanisms 21 at the same time. For example, the second conveying mechanism 32 and the first conveying mechanism 31 are aligned with two adjacent container conveying mechanisms 21 at the same time. For example, when the first conveying mechanism 31 is used to import an idle container, the second conveying mechanism 32 can be used to export a full container; when the first conveying mechanism 31 exports a full container, the second conveying mechanism 32 can be used to import an idle container. Using two conveying mechanisms for importing or exporting containers respectively can work independently and simultaneously, which helps to improve the efficiency of container replacement.

[0067] It should be noted here that the first conveying mechanism 31 and the second conveying mechanism 32 can also be used to simultaneously import empty containers into two of the multiple container conveying mechanisms 21 , or simultaneously export full containers from two container conveying mechanisms 21 .

[0068] In other embodiments, the sorting device may further include a third conveying mechanism 33, such as Fig.10 , Fig.11 As shown, the first end of each third conveying mechanism 33 is aligned with one of the container conveying mechanisms 21, and the second end is aligned with another container conveying mechanism 21; the first end and the second end of the third conveying mechanism 33 can both convey containers to their respective corresponding container conveying mechanisms 21, or can both receive containers from their respective corresponding container conveying mechanisms 21.

[0069] The third conveying mechanism 33 may also adopt a U-shaped arrangement structure, and the two ends of the U-shaped arrangement structure can be aligned with two adjacent container conveying mechanisms 21. In some embodiments, one end of the U-shaped arrangement structure is used to receive a container from one of the container conveying mechanisms 21 and introduce it to the container conveying mechanism 21 from the other end. In other embodiments, the two ends of the U-shaped arrangement structure are used to convey the container on the third conveying mechanism 33 to two adjacent container conveying mechanisms 21; or, the two ends of the U-shaped arrangement structure are used to receive containers from two adjacent container conveying mechanisms 21.

[0070] Of course, the U-shaped third conveying mechanism 33 can be a whole or divided into three sections. The two implementation modes will be described below respectively.

[0071] When the third conveying mechanism 33 is an integral unit, one end of the third conveying mechanism 33 can be used to export the fully loaded container on the corresponding container conveying mechanism 21, and then the fully loaded container is removed from the third conveying mechanism 33 by manual or automated equipment (such as a forklift, a robotic arm, etc.), and replaced with an idle container, and then the idle container is transported to the other end by the third conveying mechanism 33, and the idle container is introduced to the corresponding container conveying assembly from the other end. Of course, in this process, the goods in the fully loaded container can also be taken out manually and the container can be left on the third conveying mechanism 33, so that the container will run with the third conveying mechanism 33 and finally be introduced to the container conveying mechanism 21. In this embodiment, the third conveying mechanism 33 can realize the cyclic import or export of containers through this form, which helps to improve the efficiency of container replacement.

[0072] When the third conveying mechanism 33 is divided into three sections, that is, it includes a first linear conveying unit, an arc-shaped conveying unit and a second linear conveying unit, wherein the first linear conveying unit is aligned with one of the container conveying mechanisms 21, the second linear conveying unit is aligned with the other container conveying mechanism 21, and the arc-shaped conveying unit is connected between the first linear conveying unit and the second linear conveying unit. However, the first linear conveying unit, the second linear conveying unit and the arc conveying unit can work independently or cooperate with each other, including that the first linear conveying unit can export the full container and transport the full container to the arc conveying unit, and then take it away manually. Of course, the idle container can also be introduced to the container conveying mechanism 21; the second linear conveying unit can also realize the above process; in addition, it can also be that the first linear conveying unit exports the full container, and the full container is manually taken away at the arc conveying unit, and replaced with an idle container, and then transported to the second linear conveying unit via the arc conveying unit, and then introduced to another container conveying mechanism 21 by the second linear conveying unit. Of course, it can also be the opposite of the above process, which will not be repeated here. In this embodiment, the third conveying mechanism 33 of this form can also realize the circular import or export of containers, which helps to improve the efficiency of container replacement.

[0073] It should be noted here that the first conveying mechanism 31, the second conveying mechanism 32 and the third conveying mechanism 33 can all be conveyor belts, rollers, etc., of course, not limited to these, and other mechanisms that can achieve conveying are also applicable.

[0074] In order to allow the goods to fall smoothly from the discharge port into the container, the sorting equipment also includes a chute corresponding to the discharge port. The chute is located between the discharge port and the container. The chute is used to guide the goods output from the discharge port into the container. The chute is fixedly connected to the sorting device 10, the container conveying device 20 or the ground.

[0075] Please refer to Figure 4 and Figure 8 The sorting device may include a plurality of first chutes 115 and a plurality of second chutes 116; the number of the first chutes and the number of the second chutes are the same as the number of the container conveyor; the first chutes are aligned with the first discharge port, the second chutes are aligned with the second discharge port, the first chutes are used to guide the goods output from the first discharge port to slide into the container, and the second chutes are used to guide the goods output from the second discharge port to slide into the container. In some embodiments, the first chutes and the second chutes are both fixedly connected to the container conveyor.

[0076] For more information, see Figure 4 and Figure 8When the goods are delivered from the first discharge port 111, the first chute 115 can guide the goods delivered from the first discharge port 111, and guide the goods to fall accurately into a designated container, and the second chute 116 can guide the goods delivered from the second discharge port 112, and guide the goods to fall accurately into another designated container. The guiding effect of the two chutes helps to ensure the accuracy of goods sorting and delivery.

[0077] Furthermore, considering the positional relationship between the first chute 115 and the first discharge port 111 , the positional relationship between the second chute 116 and the second discharge port 112 , and the stability of the first chute 115 and the second chute 116 , this embodiment includes the following three chute fixing methods.

[0078] The first way: the first chute 115 and the second chute 116 are fixed on the container conveying device 20. For example, they are fixed on the rotating chassis 221 in the container conveying device 20 through a connecting rod, so that the first chute 115 and the second chute 116 can rotate synchronously with the rotating chassis 221, thereby making the first chute 115 and the second chute 116 always located above the container conveying mechanism 21 and aligned with the container, which helps to ensure the accuracy of cargo sorting and delivery.

[0079] The second mode: the first chute 115 and the second chute 116 are fixed on the sorting device 10. At this time, the first chute 115 and the second chute 116 can rotate with the sorting station 11 in the sorting device 10 to ensure that the goods can be more accurately transported from the sorting station 11 through the first chute 115 or the second chute 116 to the container.

[0080] The third mode: the first chute 115 and the second chute 116 are fixed on the ground. In this case, when the sorting device 10 and the container conveying device 20 are both stationary, the goods on the sorting station 11 can be accurately dropped into the container through the first chute 115 or the second chute 116.

[0081] In the optional technical solution of this embodiment, the width of the end of the chute close to the discharge port is not less than the width of the discharge port, and the width of the end of the chute away from the discharge port is not greater than the width of the container. Specifically, the width of the end of the first chute 115 close to the first discharge port 111 is not less than the width of the first discharge port 111, and the width of the end of the first chute 115 away from the first discharge port 111 is not greater than the width of the container; the width of the end of the second chute 116 close to the second discharge port 112 is not less than the width of the second discharge port 112, and the width of the end of the second chute 116 away from the second discharge port 112 is not greater than the width of the container.

[0082] Specifically, in order to prevent the goods from being stuck in the gap between the chute and the discharge port or the gap between the chute and the container, for the first chute 115, the width of the first chute 115 at one end adjacent to the first discharge port 111 is not less than the width of the first discharge port 111, so that the goods can slide into the first chute 115 from the narrower first discharge port 111 without hindrance, and the width of the other end of the first chute 115 is not greater than the width of the container, so that the goods can slide into the container from the narrower first chute 115 without hindrance.

[0083] For the second slide groove 116, the width of the second slide groove 116 at one end adjacent to the second discharge port 112 is not less than the width of the second discharge port 112, so the goods can slide into the second slide groove 116 from the narrower second discharge port 112 without hindrance, and the width of the other end of the second slide groove 116 is not greater than the width of the container, so the goods can slide into the container from the narrower second slide groove 116 without hindrance.

[0084] It should be noted that in order to prevent the goods from falling from the gap between the chute and other equipment, in some embodiments, brushes and other structures are provided at the upper or lower ends of the first chute 115 and the second chute 116. The brushes and other structures can block the goods, thereby preventing the goods from falling from the gap between the chute and other equipment and affecting the normal sorting process of the goods.

[0085] In other embodiments, the sorting equipment also includes a feeding device 40 for feeding goods to the sorting device 10; the feeding device 40 includes a feeding conveying component 41 and an information reading component 42, the feeding conveying component 41 is arranged on one side of the sorting device 10, the feeding conveying component 41 is used to convey the goods to the sorting station 11 aligned with it, and the information reading component 42 is arranged on the conveying path of the feeding conveying component 41, and is used to identify the information of the goods on the feeding conveying component 41.

[0086] For more information, see Figure 2In order to realize the automatic loading of goods, the aforementioned sorting equipment also includes a feeding device 40, which includes a feeding conveying component 41 and an information reading component 42. The feeding conveying component 41 is arranged on one side of the sorting device 10, for example, on the left or right side of the forward direction of the open assembly line, the inside or outside of the closed rotary assembly line, and is used to convey the goods to the sorting station 11 aligned with the feeding conveying component 41 among multiple sorting stations 11. The information reading component 42 is arranged on the conveying path of the feeding conveying component 41, and is used to read the cargo information. The feeding conveying component 41 can be any conveying component such as a conveyor belt without partitions, a conveyor belt with partitions, a conveyor roller, etc., and the information reading component 42 can be a scanning gun for reading barcode information, a camera with intelligent image recognition function, or an RFID (Radio Frequency Identification) reader. When the goods pass through the information reading component 42, the information reading component 42 can obtain the inventory information of the goods, the destination of the goods, the information of the goods themselves (such as size, name of goods, category of goods, etc.), and other information, and transport it to the designated sorting station 11 among multiple sorting stations 11 through the feeding and conveying component 41. The designated sorting station 11 is the sorting station 11 designated for the goods based on the sorting rules.

[0087] Optionally, in order to improve the feeding efficiency, two feeding devices 40 can be set in the aforementioned sorting equipment, then, the feeding conveying components 41 of the two feeding devices 40 are respectively aligned with two designated sorting stations 11 among the multiple sorting stations 11, for example, feeding device 1 is aligned with sorting station 1, and feeding device 2 is aligned with sorting station 2. The two feeding devices 40 can work independently and feed the sorting stations 11 at the same time. Of course, it is not limited to two feeding devices 40, and more can be set, and they can be respectively set corresponding to multiple sorting stations 11 to improve the feeding efficiency.

[0088] In some embodiments, the sorting device further comprises a support frame 50; the sorting device 10 is movably connected to the support frame 50, so that the sorting device 10 can move along a predetermined path relative to the support frame 50; and the container conveying device 20 is movably connected to the support frame 50. The movably connected connection here can be relative sliding or rolling.

[0089] For more information, see Fig. 9In order to simplify the assembly complexity of the entire sorting device, the rotation of the sorting device 10 can be realized by the active connection between the supporting bracket 50 and the sorting device 10, and the rotation of the container conveying device 20 can be realized by the active connection between the supporting bracket 50 and the container conveying device 20. When the sorting device 10 is a circular rotary circulation structure, the sorting device 10 and the supporting bracket 50 rotate relative to each other, and the container conveying device 20 and the supporting bracket 50 rotate relative to each other. It can be understood that the shape of the sorting device 10 can also be a rotary circulation structure of other shapes such as a rectangle or a circle. In this case, the sorting device 10 can be connected to the supporting bracket 50 by sliding, rolling or hinged, and correspondingly, the container conveying device 20 and the supporting bracket 50 can also be connected by sliding, rolling or hinged.

[0090] Optionally, the load-bearing bracket 50 includes a support bracket 51, a first rotating member 52 and a second rotating member 53; the sorting device 10 is connected to the support bracket 51 through the first rotating member 52, and the container conveying device 20 is connected to the support bracket 51 through the second rotating member 53. The rotation connection here can be hinged. Specifically, the load-bearing bracket includes a support bracket, a first slewing bearing and a second slewing bearing; the sorting device is hinged to the support bracket through the first slewing bearing, and the container conveying device is hinged to the support bracket through the second slewing bearing. This helps to improve the rotation efficiency of the sorting device 10 and the container conveying device 20, which is beneficial to improving the sorting efficiency. In this embodiment, the rotating member can be a bearing, an electric slip ring, etc., of course, it is not limited to the above methods, and it can also be any other member with the above functions, which is not limited here.

[0091] In order to improve the safety of the above equipment and prevent debris from invading the exposed parts, the main cover can be used to cover the local area enclosed by each sorting station 11 along the rotation path. It can be understood that in order to avoid interference, the maximum size of the main cover does not need to touch the discharge port near the rotation center. Similarly, the sorting cover can also be used to cover the hollow area between each two adjacent sorting stations 11.

[0092] It can be understood that in the description of the above embodiments, in order to realize the movement of various components or mechanisms, the power source can be selected as an AC motor or a stepper motor according to actual needs. Of course, the power source of the linear reciprocating motion component can also be a telescopic cylinder, etc., which is not elaborated in this embodiment.
