[0002] Warehousing logistics stations often need to sort the logistics parts that arrive at the stations. Automated intelligent logistics sorting lines are an indispensable part of helping stations improve sorting efficiency.

[0003] Intelligent logistics sorting lines can efficiently sort and transport items at high speed to maximize the efficiency of logistics transportation. However, when sorting, fragile items are different from ordinary items. They are very easy to be damaged when they are hit or the sorting action is too intense during the sorting process. When sorting, fragile items are mixed with non-fragile items. If fragile items and non-fragile items are not separated in advance, it is easy to affect the speed of logistics sorting or cause fragile items to be damaged.

[0004] Although some logistics sorting lines in the prior art can separate fragile items from non-fragile items in advance, after the fragile packages are separated and enter the receiving area, they are still prone to collide with the fragile packages that have previously entered the receiving area, thereby causing damage to the fragile items.

[0032] The following is combined with Figure 1-4 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] The intelligent warehousing logistics sorting line provided by the present invention comprises a fragile goods conveying mechanism 1 for conveying diverted fragile goods packages, a ring-shaped conveying mechanism 2 and a plurality of supporting components. The bottom of the fragile goods conveying mechanism 1 is provided with a pressing guide rail 11 arranged along the conveying direction of the fragile goods conveying mechanism 1. Specifically, the fragile goods conveying mechanism 1 comprises a support frame 12 and a conveyor belt device 13. The conveyor belt device 13 is installed on the top of the support frame 12. The conveyor belt device 13 comprises two conveying wheels and a transmission belt wound around the conveying wheels. The conveying wheels are rotatably installed on the support frame 12 and driven to rotate by a motor connected to a power supply. The pressing guide rail 11 is fixedly connected to the support frame 12 and is located below the conveyor belt device 13. The end of the pressing guide rail 11 away from the tail of the fragile goods conveying mechanism 1 is provided with a first inclined surface 111. The ring-shaped conveying mechanism 2 and a plurality of supporting components are also provided. At least part of the conveying track is arranged along the conveying track of the conveyor belt device 13, and the part of the annular conveying mechanism 2 is located directly below and behind the tail of the conveyor belt device 13. A plurality of support components are evenly arranged along the annular conveying mechanism 2, and the support components include a spring rod 31 and a support platform 32. The spring rod 31 is vertically connected to the annular conveying mechanism 2 through the bottom end. A pressing block 311 is fixedly connected to the spring rod 31. A second inclined surface is arranged on the front side of the pressing block 311, so that the pressing block 311 is pressed against the first inclined surface 111 through the second inclined surface, so that the position of the pressing block 311 is lowered until the top surface of the pressing block 311 is pressed against the pressing guide rail 11. At this time, the top surface of the support platform 32 is lower than the bottom surface of the transmission belt. The support platform 32 is fixedly connected to the top end of the corresponding spring rod 31. The support platform 32 has a top surface, and the maximum height of the top surface of the support platform 32 is flush with the top surface of the annular conveying mechanism 2.

[0034] The fragile package conveyed by the tail of the fragile conveying mechanism 1 can be directly conveyed to the top surface of each support platform 32 whose maximum height is flush with the top surface of the ring conveying mechanism 2. In this way, the fragile package will not be vibrated when being conveyed out of the fragile conveying mechanism 1, which can prevent the fragile package from being hit, thereby preventing the fragile package from being damaged;

[0035] When the fragile package is conveyed from the fragile conveying mechanism 1 to the ring conveying mechanism 2, the conveying speed of the ring conveying mechanism 2 is controlled to be consistent with the conveying speed of the fragile conveying mechanism 1. In this way, it is possible to avoid a sudden change in the speed of the fragile package when it is conveyed from the fragile conveying mechanism 1 to the ring conveying mechanism 2, which may cause the fragile package to vibrate.

[0036] By pressing the second inclined surface of the pressing block 311 on the spring rod 31 against the first inclined surface 111 of the pressing guide rail 11, the position of the pressing block 311 is lowered, the spring rod 31 can be shortened, and the support platform 32 on the spring rod 31 can be lowered to the bottom of the fragile article conveying mechanism 1 to avoid collision between the support platform 32 and the fragile article conveying mechanism 1.

[0037] As a preferred embodiment, the fragile goods conveying mechanism 1 is provided with a length sensor 4 for detecting the length of the fragile goods package. Specifically, the length sensor 4 is a pair of infrared tubes, and the two infrared tubes are respectively arranged on both sides of the conveyor belt device 13. The length sensor 4 and the driver of the ring conveying mechanism 2 are both connected to the controller signal. The controller has multiple timing modules. When the fragile goods package is blocked between the infrared tubes, the controller can measure the signal duration when the infrared tubes are blocked through the timing modules, and obtain the transportation time t of the fragile goods package at the speed v. Since the speed v of the conveyor belt device 13 during transportation is fixed, the length L of the fragile goods package is obtained, so that the length L can be set according to the length L each time the fragile goods package is transported from the fragile goods conveying mechanism 1 to the ring conveying mechanism 2, so that the conveying length of the ring conveying mechanism 2 is slightly greater than the length L, thereby maximizing the use of the space of the ring conveying mechanism 2 while avoiding collisions between fragile goods packages.

[0038] As a preferred embodiment, the support platform 32 is rectangular, and the length direction of the support platform 32 is perpendicular to the tangent direction of the ring conveying mechanism 2, so that the length of the support platform 32 is sufficient to support the fragile package, and the width of the support platform 32 supported under the fragile package is smaller. When the ring conveying mechanism 2 performs the conveying movement, the distance between the fragile packages can be reduced as much as possible.

[0039] As a preferred embodiment, a third inclined surface 112 is provided at one end of the pressing guide rail 11 close to the tail of the fragile goods conveying mechanism 1, and a fourth inclined surface is provided on the rear side of the pressing block 311, so that when the pressing block 311 is separated from the pressing guide rail 11, the fourth inclined surface and the third inclined surface 112 are abutted against each other, so that the pressing block 311 is gradually raised. When the annular conveying mechanism 2 is conveying, the pressing block 311 will gradually separate from the pressing of the pressing guide rail 11, and the spring rod 31 will reset and extend. In order to prevent the spring rod 31 from suddenly bouncing up and causing the support platform 32 to quickly hit the bottom of the fragile goods package, the fourth inclined surface and the third inclined surface 112 are provided in the present invention, so that the spring rod 31 can extend at a lower speed when extending, thereby preventing the fragile goods package from being hit.

[0040] As a preferred embodiment, the spring rod 31 is a spring damping rod, which can further reduce the extension speed of the spring rod 31 .

[0041] As a preferred embodiment, the top surface of the support platform 32 is a rough surface, which can prevent the fragile package from sliding off the top surface of the support platform 32.

[0042] As a preferred embodiment, the pressing guide rails 11 include two pressing guide rails 11, which are respectively arranged on both sides of the bottom of the fragile goods conveying mechanism 1. Two pressing blocks 311 are connected to the spring rod 31. The two pressing blocks 311 are respectively located on both sides of the symmetrical axis of the support platform 32 with the motion trajectory of the center of the support platform 32 as the axis. Specifically, two spring rods 31 are symmetrically connected to the bottom of each support platform 32, and a pressing block 311 is respectively arranged on the side away from each other at the top of the spring rod 31. The pressing blocks 311 correspond to the positions of the pressing guide rails 11, so that the two pressing blocks 311 can be pressed on the pressing guide rails 11, respectively. The bottom ends of the two pressing blocks 311 are fixedly connected to the annular conveying mechanism 2 through a fixing seat 21. By adopting the above technical scheme, the two symmetrical spring rods 31 can be pressed at the same time by the two pressing guide rails 11, so that the rising and falling speeds of the two sides of the support platform 32 can be consistent, thereby avoiding instability.

[0043] As a preferred embodiment, the head of the fragile goods conveying mechanism 1 is provided with a diverting mechanism 5. Specifically, the diverting mechanism 5 can be a pendulum sorting machine. The input end of the diverting mechanism 5 is provided with a main conveying mechanism 6. The main conveying mechanism 6 is provided with a code scanning device 61, so that the barcode or QR code on the fragile goods package can be identified by the code scanning device 61 to distinguish between fragile goods packages and non-fragile goods packages. Specifically, the code scanning device 61 can be a QR code scanner or a barcode scanner fixedly arranged above or on both sides of the main conveying mechanism 6. The output end of the diverting mechanism 5 is connected to the head of the fragile goods conveying mechanism 1 and the head of the non-fragile goods conveying mechanism 7, so as to distinguish the fragile goods packages and non-fragile goods packages conveyed by the main conveying mechanism 6. The fragile packages are conveyed to the fragile conveying mechanism 1 and the non-fragile conveying mechanism 7 respectively. The conveying direction of the fragile conveying mechanism 1 is consistent with the conveying direction of the main conveying mechanism 6, the conveying speed of the fragile conveying mechanism 1 is consistent with the conveying speed of the main conveying mechanism 6, and the conveying speed of the non-fragile conveying mechanism 7 is greater than the conveying speed of the fragile conveying mechanism 1. The above technical scheme can be adopted to divert the packages, increase the transportation speed of the non-fragile packages and thus improve the transportation efficiency. Moreover, since the conveying direction of the fragile conveying mechanism 1 is consistent with the conveying direction of the main conveying mechanism 6, there is no need to change direction when the fragile packages pass through the diversion mechanism, thereby avoiding collision of the fragile packages during transportation.

[0044] As a preferred embodiment, the angle between the conveying direction of the non-fragile conveying mechanism 7 and the conveying direction of the fragile conveying mechanism 1 is between 30° and 50°. By adopting the above technical solution, when conveying non-fragile packages, the collision of the non-fragile packages can be reduced due to the smaller changed direction angle.

[0045] A method for using an intelligent warehousing logistics sorting line, using the intelligent warehousing logistics sorting line with the length sensor 4 and the controller, comprises the following steps:

[0046] S1: The fragile packages are diverted to the conveyor device 13 and the length is detected by the length sensor 4. The length sensor 4 sends the length signal of the fragile package to the controller. At the same time, every time the front end of a fragile package passes the length sensor 4, a timing module starts timing;

[0047] S2: Since the distance s from the length sensor 4 to the tail of the conveyor belt device 13 is fixed, the timing time of the timing module can be set to T=s / v. When the timing time of a timing module reaches the set time T, the front end of the fragile package reaches the tail of the conveyor belt device 13, and the controller controls the annular conveying mechanism 2 to start, and the conveying speed of the annular conveying mechanism 2 is consistent with the conveying speed of the conveyor belt device 13, until the moving distance of the annular conveying mechanism 2 is greater than or equal to the length of the corresponding fragile package, and the controller controls the annular conveying mechanism 2 to gradually decelerate until it stops running;

[0048] By adopting the above technical scheme, it is possible to maximize the use of the space of the ring conveyor mechanism 2 while avoiding collisions between fragile packages. Moreover, the position of each package on the ring conveyor mechanism 2 can be determined through the above technical scheme, thereby facilitating the classification and collection of packages. In addition, it is also possible to save power for driving the ring conveyor mechanism 2.

In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
