[0026] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0028] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0029] like Figure 1 and Figure 2 As shown, a box conveying device of one embodiment includes a frame 1, on which a box assembly 2 and a conveyor line 3 are provided, the box assembly 2 includes a driving mechanism 21 and three box plates 22, the driving mechanism 21 includes a driving shaft 211, a rotating frame 212 and three connecting shafts 213, one end of the connecting shaft 213 is arranged on the rotating frame 212, the box plate 22 is fixed to the other end of the connecting shaft 213, the axis of the connecting shaft 213 is parallel to the axis of the driving shaft 211, the driving shaft 211 is fixedly connected to the rotating frame 212 and can drive the rotating frame 212 to rotate, so that the box plate 22 rotates around the driving shaft 211 and selectively moves the cargo box 100 on the conveyor line 3.

[0030] The box conveying equipment of this embodiment utilizes a rotating box plate 22 to selectively contact the cargo box 100 on the conveyor line 3, and changes the movement state of the cargo box 100 by applying a force to the cargo box 100 during the movement of the box plate 22, and moves the cargo box 100 to a desired position to realize lane conveyance of the cargo box 100 on the conveyor line 3. Compared with the existing solution of using a cylinder to change the position of the cargo box 100, the box plate 22 has less impact force on the cargo box 100, and the cargo box 100 and the products inside the cargo box 100 are not easily damaged. At the same time, it also avoids the cylinder loss and the use of a large amount of compressed gas caused by the use of cylinders, and has the advantage of low cost of use.

[0031] The box splitting assembly 2 of this embodiment includes three box splitting plates 22, and correspondingly, the number of connecting shafts 213 is also three. When the driving shaft 211 drives the rotating frame 212 to rotate one circle, each box splitting plate 22 can interact with one cargo box 100 respectively. Therefore, after the rotating frame 212 rotates one circle, it can realize the lane-by-lane transportation operation of up to three cargo boxes 100, with high diversion efficiency. However, due to size limitations, the number of box splitting plates 22 is not necessarily the more the better, and three box splitting plates 22 are the preferred choice.

[0032] like Figure 3 and Figure 4 As shown, further, the driving mechanism 21 also includes a center pulley 214, a synchronous belt 215 and three planetary pulleys 216. The center pulley 214 is fixedly connected to the frame 1. The center pulley 214 and the planetary pulleys 216 are both arranged in the rotating frame 212. The center pulley 214 and the planetary pulleys 216 are connected by the synchronous belt 215. The axis of the center pulley 214 coincides with the axis of the driving shaft 211. The connecting shaft 213 is connected to the planetary pulleys 216 and rotates with the planetary pulleys 216. When the planetary pulley 216 revolves around the drive shaft 211, it also rotates due to the action of the synchronous belt 215. When the planetary pulley 216 and the center pulley 214 adopt the same specifications, the revolution period of the planetary pulley 216 is equal to its own rotation period, so that the connecting shaft 213 connected to the planetary pulley 216 does not rotate during the entire movement process. The dividing plate 22 fixed on the connecting shaft 213 can maintain its own posture unchanged when it revolves around the drive shaft 211. Corresponding to this embodiment, the dividing plate 22 always remains perpendicular to the conveying surface of the conveyor line 3, so that it can maintain good contact with the cargo box 100 on the conveyor line 3, achieving a better diversion effect.

[0033] In this embodiment, three planetary belt wheels 216 are arranged at equal intervals on a circle with the center of the central belt wheel 214 as the center, so that during the rotation of the sub-box assembly 2, the position of its center of gravity can be kept stable and the vibration generated is small. When the number of the planetary belt wheels 216 is two, the two planetary belt wheels 216 are symmetrically arranged about the central belt wheel 214, and the axis of the central belt wheel 214 and the axes of the two planetary belt wheels 216 are all on the same plane, so that the sub-box assembly 2 can also be operated smoothly.

[0034] Furthermore, the driving mechanism 21 also includes a bearing 217, which is arranged on the rotating frame 212, and the connecting shaft 213 passes through the bearing 217 and is connected to the planetary pulley 216. When the box plate 22 interacts with the cargo box 100, the cargo box 100 will exert a reaction force on the box plate 22, and the bearing 217 can support the connecting shaft 213 in the radial direction, so that the connecting shaft 213 has better stability. In addition, although in theory the connecting shaft 213 can not rotate during the movement, at certain moments, such as when the device is just started, the connecting shaft 213 may still rotate briefly, so it is also necessary to provide a bearing 217.

[0035] like Figure 4 As shown, the driving mechanism 21 further includes two idler wheels 218, which are respectively arranged on both sides of the central pulley 214 and symmetrical about the axis of the central pulley 214, and the idler wheels 218 are connected to the synchronous belt 215. The idler wheels 218 can increase the wrap angle of the central pulley 214, and the synchronous belt 215 can play a better role, so that the operation of the box assembly 2 is more stable.

[0036] Furthermore, the driving mechanism 21 also includes a tensioning wheel 219, which is arranged on the rotating frame 212. The tensioning wheel 219 is connected to the synchronous belt 215, so that the synchronous belt 215 can be better connected with the center pulley 214 and the planetary pulleys 216, thereby ensuring the synchronization of the planetary pulleys 216.

[0037] The synchronous belt 215 used in this embodiment can be replaced by a chain, and correspondingly, the central pulley 214 and the planetary pulleys 216 can be replaced by sprockets.

[0038] like Figure 3 and Figure 4 As shown, the box assembly 2 of this embodiment also includes a fixing mechanism 23, and the box plate 22 is connected to the connecting shaft 213 by the fixing mechanism 23. The fixing mechanism 23 includes a fixing clamp 231, a support rod 232 and a fixing seat 233. The fixing clamp 231 is fixed on the connecting shaft 213, the support rod 232 is fixed on the fixing clamp 231, and the fixing seat 233 is connected to the box plate 22 and fixed on the support rod 232. The connecting shaft 213 is a cylindrical object, and the box plate 22 is a flat object. It is difficult to directly connect the two. The fixing clamp 231 in the fixing mechanism 23 can be well fixed on the connecting shaft 213 by virtue of its own structure. By adjusting the position of the fixing clamp 231 holding the support rod 232, the setting position of the box plate 22 can be changed. The fixing seat 233 is a block structure, which is convenient for fixing on the box plate 22, thereby realizing the stable fixation of the box plate 22, and also has an adjustable function.

[0039] like Figure 2As shown, in this embodiment, the conveying line 3 includes a feed line 31, a box dividing line 32 and a diverter line 33 which are sequentially arranged along the conveying direction of the cargo box 100, the box dividing assembly 2 is arranged above the box dividing line 32, the diverter line 33 includes a first diverter channel 331 and a second diverter channel 332, and the box dividing plate 22 selectively moves the cargo box 100 on the box dividing line 32 to cause the cargo box 100 to selectively enter the first diverter channel 331 or the second diverter channel 332. The number of diverter channels included in the diverter line 33 can also be more than three, and accordingly, the number of box dividing assemblies 2 can also be increased. For example, when the diverter line 33 includes four diverter channels, a box dividing assembly 2 can be respectively arranged on both sides of the frame 1, and each box dividing assembly 2 can push the cargo box 100 located on the outside of the box dividing line 32 to the middle area of ​​the box dividing line 32.

[0040] In this embodiment, the conveying direction of the diverter line 33 is the same as the conveying direction of the feed line 31 . In other embodiments, the conveying direction of the diverter line 33 may be different from the conveying direction of the feed line 31 .

[0041] like Figure 5 As shown, in a specific embodiment, the conveying direction of the shunt line 33 is perpendicular to the conveying direction of the feed line 31, and the shunt line 33 includes a first shunt channel 331 and a second shunt channel 332, and the first shunt channel 331 and the second shunt channel 332 are respectively connected to a box dividing line 32, and a box dividing assembly 2 is provided above each box dividing line 32, and the box dividing assembly 2 is directly opposite to the first shunt channel 331 or the second shunt channel 332. When the shunt line 33 includes three shunt channels, the number of the box dividing assemblies 2 becomes three accordingly.

[0042] Of course, the conveying direction of the diversion line 33 can also be at other angles with the conveying direction of the feed line 31, and is not limited to the special case of being perpendicular to each other.

[0043] In addition, the box conveying equipment may also include a detection mechanism (not shown in the figure), which may include a photoelectric sensor or other types of sensors. The sensor may be set on the frame 1 to detect the real-time position of the cargo box 100 on the conveyor line 3. The detection mechanism is electrically connected to the box assembly 2 so that the box plate 22 can contact the cargo box 100 more accurately, thereby improving the accuracy and smoothness of the box process.
