Embodiments for Carrying Out the Invention

[0024] The technical solutions provided in the present disclosure will be described in more detail in relation to FIGS. 1 to 14.

[0025] In the field of logistics sorting and transportation, article sorting and transportation devices are used to transport and sort items. The movement of items includes two main categories, namely, transportation movement and sorting movement. The transportation movement means transporting an item from a certain position to a set position by the transportation assembly 1. The sorting movement means moving the item from the transportation assembly 1 so that the item is taken out from the transportation assembly 1. More specifically, sorting is also a process of taking out an item from the article transportation assembly 2.

[0026] In some embodiments of the present disclosure, the transportation movement is implemented by the transportation assembly 1. Specifically, the transportation assembly 1 is implemented, for example, by the cooperation of a sprocket 11 and a chain 12. The sorting movement is implemented by the article transportation assembly 2.

[0027] As can be seen with reference to FIGS. 1 to 7, some embodiments of the present disclosure provide an article sorting and transportation device including a transportation assembly 1, an article transportation assembly 2, and a drive assembly 3.

[0028] The transportation assembly 1 is configured to move cyclically. The transportation assembly 1 performs a transportation movement together with the article transportation assembly 2 on the transportation assembly 1.

[0029] Referring to FIGS. 1 to 7, the conveying assembly 1 includes a sprocket 11 and a chain 12. Two groups of sprockets 11 are provided, and the chain 12 is wound around the two groups of sprockets 11 and tensioned by the two groups of sprockets 11. The sprockets 11 on one side are shown in FIGS. 1 and 2. One of the two groups of sprockets 11 acts as a driving sprocket, and the other set acts as a driven sprocket. The driving sprocket 11 is driven by an external force. The driving sprocket is connected to the driven sprocket via the chain 12, and the driven sprocket rotates with the rotation of the driving sprocket. Each group has one or more sprockets 11. The conveying assembly 1 includes a plurality of groups of sprockets 11 and a chain 12 to make the conveying movement of the article conveying assembly 2 smoother. Each group of sprockets 11 and the chain 12 include one chain 12 and two sprockets 11. Each sprocket 11 in the group of sprockets 11 and the chain 12 cooperate with each other and are arranged in parallel to convey the article conveying assembly 2 together. The longitudinal directions of the plurality of groups of the chain 12 are all the same as the direction of the conveying movement. In some embodiments shown in FIGS. 1 and 2, two sprockets 11 are provided at each end of the conveying direction (i.e., the first direction A), and the two sprockets 11 are provided parallel to each other and arranged at the two ends in the longitudinal direction of the article conveying assembly 2 (i.e., the second direction B).

[0030] An external force rotates the sprocket, and the driving sprocket circulates the chain 12. The article conveying assembly 2 is attached to the chain 12 and moves with the chain 12. Items are placed on the article conveying assembly 2 and move and are conveyed with the rotation of the sprocket 11.

[0031] As can be seen with reference to FIGS. 1 and 2, the chain 12 includes a plurality of links that are sequentially rotatably connected. The rotatable connection between two adjacent links is also specifically connected to the article conveying assembly 2, for example, by a pin shaft, and the pin shaft connects two adjacent links and the article conveying assembly 2. In this way, the chain 12 enables the article conveying assembly 2 to move together with the chain 12 during the circulating movement, that is, to realize the conveying movement.

[0032] As can be seen with reference to FIGS. 1 to 7, the article conveying assembly 2 includes a conveyor belt 21. The conveyor belt 21 is disposed on the conveying assembly 1, and the conveyor belt 21 is driven by the conveying assembly 1 to move in a first direction A. The first direction A is the direction of the conveying movement and refers to the direction indicated by arrow A in FIG. 2.

[0033] As can be seen with reference to FIGS. 1 to 7, in some embodiments, the article conveying assembly 2 further includes a carriage 22, a roller 23, and a drive belt 24.

[0034] The carriage 22 is a load-bearing base for the article conveying assembly 2 and a mounting base for other components of the article conveying assembly 2. The carriage 22 is configured in a strip shape. During the sorting movement, the carriage 22 does not move, and the sorting movement is the movement of the conveyor belt 21 relative to the carriage 22.

[0035] In some embodiments, the carriage 22 is configured in a strip shape, and the rollers 23 are disposed at two end portions 232 of the carriage 22. The carriage 22 functions to support and hold the rollers 23. The length direction of the carriage 22 is a second direction B as shown in FIG. 3. The rollers 23 are provided at each end in the length direction of the carriage 22. The rollers are rotatably attached to the carriage 22. Specifically, as shown in FIGS. 5 to 7, the roller 23 is rotatably attached to a roller mounting sheet 27, and the roller mounting sheet 27 is fixed to the carriage 22.

[0036] As can be seen by referring to FIGS. 4 to 7, the roller 23 is used to attach the conveyor belt 21 and moves the conveyor belt 21. Specifically, the drive assembly 3 moves the roller 23, and the roller 23 moves the sprocket conveyor belt 21 by friction.

[0037] The motive power of the roller 23 is the force generated by the drive of the drive assembly. Specifically, the drive assembly 3 rotates the drive belt 24, whereby the item placed on the conveyor belt 21 moves to the edge of the conveyor belt 21 and falls under the action of gravity and inertia.

[0038] As can be seen by referring to FIGS. 1 to 7, the drive belt 24 is drivably connected to the roller 23, and the drive belt 24 rotates the roller 23. The drive belt 24 is fixedly connected to the drive member 32. The conveyor belt 21 is drivably connected to the roller 23 and is driven by the roller 23. In the initial state, the drive member 32 is located, for example, at the center in the longitudinal direction of the carriage 22.

[0039] As can be seen by referring to FIGS. 1 to 7 and FIG. 14, from the above structure, it can be seen that two belts, namely, the drive belt 24 and the conveyor belt 21, are wound around the rollers 23 located at the two ends of the carriage 22. The drive belt 24 receives the driving force from the drive assembly 3 and then transmits the driving force to the conveyor belt 21 through the intermediate transfer component. The specific transmission process of the motive power is as follows. The drive source 31 of the drive assembly 3 linearly moves the drive member 32, and the drive member 32 is fixed together with the drive belt 24. The drive belt 24 is drivably connected to the roller 23. When the drive belt 24 moves, the roller 23 rotates, and the rotation of the roller 23 causes the conveyor belt 21 to rotate. The item is placed on the conveyor belt 21. When the conveyor belt 21 moves, the item moves from the central part of the conveyor belt 21 to the edge of the conveyor belt 21, and then the item falls under the action of inertia and gravity.

[0040] As can be seen with reference to FIGS. 5 to 7 and FIG. 14, in some embodiments, the diameter of the central portion 231 of each roller 23 is smaller than the diameters of the two end portions 232 of the roller 23. The central portion 231 of the roller 23 is drivably connected to the drive belt 24, and the two end portions 232 of the roller 23 are drivably connected to the conveyor belt 21.

[0041] Since the diameter of the central portion 231 of the roller 23 is smaller, the central portion 231 of the roller 23 is drivably connected to the drive belt 24. Since the diameters of the two end portions 232 of the roller 23 are larger, the two end portions 232 of the roller 23 are drivably connected to the conveyor belt 21. The conveyor belt 21 is located near the edge on the outside, and the drive belt 24 is located near the center on the inside. This arrangement can achieve that when the drive belt 24 travels a distance S, the conveyor belt 21 travels a distance n times that of S. The value of n is greater than 1. In some embodiments, the corresponding ratio of these distances is, for example, such that when the drive belt 24 travels a distance S, the conveyor belt 21 travels a distance shorter than 2S and longer than S, whereby the items at the edge of the conveyor belt 21 can be moved to the edge on the other side and removed from the conveyor belt 21.

[0042] As can be seen with reference to FIGS. 1 and 14, in some embodiments, the central portion 231 of the roller 23 includes first anti-slip teeth 233 that cooperate with the drive belt 24. The first anti-slip teeth 233 are a toothed structure arranged in a circular shape.

[0043] As can be seen with reference to FIGS. 1 and 14, in some embodiments, at least one of the two end portions 232 of the roller 23 includes second anti-slip teeth 234 that engage with the conveyor belt 21. The second anti-slip teeth 234 are a toothed structure arranged in a circular shape. In some embodiments, each of the two end portions 232 of the roller 23 includes circular second anti-slip teeth 234.

[0044] As can be seen with reference to FIGS. 7 to 12, in some embodiments, the article conveying assembly 2 further includes a slider 25. The driving member 32 is fixedly connected to the driving belt 24 via the slider 25. The driving member 32 is coupled to, welded to, or threadably connectable to the slider 25. The carriage 22 is provided with a guide slot 221. The guide slot 221 extends in the same direction as the second direction B. The slider 25 is attached to the guide slot 221. Providing the slider 25 can make the linear motion of the driving member 32 smoother, thereby making the rotation of the driving belt 24 driven by the driving member 32 smoother and more reliable, and also making the rotation of the roller 23 smoother. Therefore, the movement of the conveyor belt 21 driven by the roller 23 becomes smoother, and the tendency to vibrate during movement is reduced.

[0045] As can be seen with reference to FIGS. 1 and 2, in some embodiments, in order to make the conveying motion of the conveyor belt 21 smoother, the article sorting and conveying device further includes a guiding assembly 4. The guiding assembly 4 is fixedly arranged on the floor of the factory building or on other fixed equipment. The guiding assembly 4 is configured to guide the conveying motion of the article conveying assembly 2. The driving source 31 is fixed to the guiding assembly 4.

[0046] As can be seen with reference to FIGS. 1 and 2, the article conveying assembly 2 includes a guide wheel 26. The guide wheel 26 is pivoted with respect to the chain 12 of the conveying assembly 1. The guiding assembly 4 includes a guiding groove 41. The guide wheel 26 is configured to move along the guiding groove 41.

[0047] As can be seen with reference to FIGS. 1 and 2, in some embodiments, the guide wheel 26 is attached to the bottom of the carriage 22. The axis of the guide wheel 26 is pivoted to the two adjacent links described above.

[0048] As can be seen with reference to FIGS. 1 and 2, two guide assemblies 4 are provided, and one or more guide wheels 26 are provided on each side of the bottom of the carriage 22 of the article conveying assembly 2. The guide groove 41 extends in the same direction as the first direction, and the guide wheel 26 moves along the guide groove 41 of the guide assembly 4.

[0049] Other implementation forms of the roller 23 will be described below.

[0050] In other embodiments, the rollers 23 located at each end of the carriage 22 include a plurality of independent rollers 23 rather than being an integral body. Specifically, the rollers 23 located at each end of the carriage 22 include a first roller and a second roller. The first roller is rotatably attached to the carriage 22 and is drivably connected to the drive belt 24. The second roller is rotatably attached to the carriage 22 and is driven coaxially with the first roller. The diameter of the first roller is smaller than the diameter of the second roller, and the second roller is drivably connected to the conveyor belt 21.

[0051] In other embodiments, the first roller is drivably engaged with the drive belt 24, and the second roller is drivably engaged with the conveyor belt 21. The first roller and the second roller located at the same end of the carriage 22 are attached to the same rotation axis, that is, the rotation center lines of the first roller and the second roller are coaxial. The power transmission path is as follows. The drive source 31 linearly moves the drive member 32, and the drive belt 24 fixedly connected to the drive member 32 is moved, whereby the first roller rotates. The first roller rotates the second roller coaxial therewith via the rotation axis. When the second roller rotates, the conveyor belt moves. Due to the relatively short movement path required for the sorting movement, the conveyor belt 21 does not move circularly in the 360-degree range. Instead, the conveyor belt 21 moves only in the range of moving the item located on the conveyor belt 21 from an arbitrary position on the conveyor belt 21 to the edge of the conveyor belt 21 where the required sorting port for sorting is located. Different rollers 23 cooperate with the drive belt 24 and the conveyor belt 21 respectively, thereby facilitating processing and manufacturing.

[0052] How to perform the sorting movement will be described below.

[0053] The sorting movement is performed such that the drive assembly 3 moves the conveyor belt 21. The sorting movement is independent of the conveying movement. In other words, the conveying movement of the conveyor belt 21 is performed such that the conveying assembly 1 moves the entire article conveying assembly 2, and the sorting movement is the movement of the conveyor belt 21 relative to the conveying assembly 1. The sorting movement of the article conveying assembly 21 exists regardless of whether the conveying assembly 1 moves.

[0054] The drive assembly 3 includes a drive source 31 and a drive member 32. The drive source 31 does not move with the conveying movement nor with the sorting movement. The drive source 31 is fixed at a position corresponding to the sorting port. The drive source 31 is connected to the drive member 32 in a non-contact drivable manner. The drive member 32 is attached to the article conveying assembly 2, and the drive assembly 3 is configured to move the conveyor belt 21 in a second direction which is the direction of the sorting movement. The first direction and the second direction intersect each other, such as being perpendicular to each other.

[0055] The drive source 31 and the drive member 32 are not in contact with each other and are separated by a certain distance, that is, there is a gap between the drive source 31 and the drive member 32. Only the drive member 32 needs to be arranged on the article conveying assembly 2, and there is no need to arrange control components such as power sources and signal transmission components on the article conveying assembly 2. Thereby, the complexity of the structure of the article conveying assembly 2 is significantly reduced, and furthermore, the reliability of the article conveying assembly 2 is improved.

[0056] In an actual application example, the position of the sorting port is determined as a reference, the drive source 31 is installed at a position corresponding to the sorting port, and a common drive source is used as the drive source 31. In some of the above-described embodiments, the article sorting and conveying device further includes a guiding assembly 4 for guiding the article conveying assembly 2, and the drive source 31 is fixed to the guiding assembly 4. For example, the entire article sorting and conveying device includes four sorting ports M1, M2, M3, and M4. One drive source 31 is provided for each of the four sorting ports M1, M2, M3, and M4. All the article conveying assemblies 2 are provided only with the drive member 32. When it is necessary to sort an item from the sorting port M1, the drive source 31 at the sorting port M1 is started. When the article conveying assembly 2 is transferred to the sorting port M1, the drive source 31 moves the conveyor belt 21 of the article conveying assembly 2 to drop the item from the conveyor belt 21 to the corresponding sorting port.

[0057] In the above technical solution, since the drive sources 31 of each sorting port are common, it is not necessary to provide both the drive source 31 and the drive unit 32 on the article conveying assembly 2. On the one hand, the number of required drive sources 31 is significantly reduced. On the other hand, the entire article sorting and conveying device becomes smaller and the number of components required to achieve the same performance is reduced. Therefore, the structure of the article sorting and conveying device is optimized.

[0058] In some embodiments, the drive assembly 3 includes a linear motor. The drive source 31 includes a primary part, and the drive member 32 includes a secondary part. The primary part and the guide assembly 4 are attached to each other, and the primary part and the guide assembly 4 are fixed together and cannot move. The secondary part moves together with the conveying movement of the article conveying assembly 2. When the secondary part moves to a position where it can be driven by the primary part, the primary part linearly moves the secondary part, and then the movement of the secondary part is converted into the movement of the conveyor belt 21 by the components of the article conveying assembly 2 described above.

[0059] Specifically, the article conveying assembly 2 includes a secondary part that is slidable at the bottom, and the belt of the article conveying assembly 2 is fixedly connected to the secondary part. When the secondary part is excited by the linear motor, the secondary part moves left or right according to the excitation direction, whereby the conveyor belt 21 rotates and the items on the article conveying assembly 2 are put into the port. As the article conveying assembly 2 sequentially passes through the sorting ports, one drive source 31 provided at the sorting port drives all the drive members 32 passing through the sorting port, whereby the number of required drive sources 31 is reduced, and the article sorting and conveying device can have a more reasonable and smaller structure and better performance.

[0060] Some embodiments of the present disclosure are an article sorting and conveying system including a sorting port and an article sorting and conveying device provided in any technical solution of the present disclosure, and the sorting port further provides an article sorting and conveying system corresponding to the drive source 31 of the drive assembly 3.

[0061] In some embodiments, a plurality of sorting ports are provided, and each of the sorting ports includes at least one corresponding drive source 31.

[0062] The article sorting and conveying system provided by the above technical solution has the structures and features of the above-mentioned article sorting and conveying device, and these structures and features will not be repeatedly described herein.

[0063] In the description of the present disclosure, orientation relationships or positional relationships such as "center", "longitudinal direction", "lateral direction", "front part", "rear part", "left", "right", "vertical", "horizontal", "top", "bottom", "inner side", "outer side", etc. are exemplary orientation or positional relationships based on the drawings, and do not indicate or imply that the illustrated devices or elements must have a specific orientation or be configured and operate in a specific orientation. Instead, they are only for the convenience of describing the present disclosure and simplifying the description. Therefore, it should be understood that these terms cannot be construed as limiting the protection scope of the present disclosure.

[0064] Finally, it should be noted that the above embodiments are not used to limit the technical solution of the present disclosure but only for the purpose of explanation. Although the present disclosure has been described with reference to preferred embodiments, those skilled in the art can still modify specific implementation forms in the present disclosure or perform equivalent substitutions for some of the technical features of the present disclosure. Such modifications and equivalent substitutions should be included within the scope of the technical solutions required for protection in the present disclosure as long as they do not deviate from the spirit of the technical solution of the present disclosure.
