Specific embodiments
[0016] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0017] Referring to Figure 1 , Figure 2 As shown, a multi-channel parcel confluence landslide conveying system includes a main conveying line 1 and several conveying branch lines 2. This embodiment is used for multi-layer parcel sorting. The highest part is the high-level platform 100, the lowest part is the low-level platform 200, and the middle-level platform 300 is located between the high-level platform 100 and the low-level platform. Parcel sorting lines 400 are provided on both the high-level platform 100 and the middle-level platform 300. Thus, the parcel sorting lines 400 on each layer are used to sort and convey parcels. The input end of the main conveying line 1 is arranged on the high-level platform 100, the output end of the main conveying line 1 is arranged on the low-level platform 200. The output end of the conveying branch line 2 is connected to the main conveying line 1 through a confluence device 5. The input end of the conveying branch line 2 is arranged on the middle-level platform 300. A swing wheel sorter is arranged between each parcel sorting line 400 and the main conveying line 1 and the conveying branch line 2, so that the parcel sorting line on the high-level platform 100 sends parcels onto the main conveying line 1 through the swing wheel sorter, enabling the parcels sorted on the high-level platform 100 to be conveyed from the high place to the low place of the main conveying line 1. The input end of the conveying branch line 2 is arranged on the middle-level platform 300, so that the parcel sorting line on the middle-level platform 300 sends the sorted parcels onto the conveying branch line 2 through the swing wheel sorter, enabling the parcels sorted on the middle-level platform 300 to flow into the main conveying line 1 from the conveying branch line 2, thereby realizing the confluence conveying of multi-layer parcels.
[0018] Referring to Figure 2As shown, in this embodiment, a plurality of conveying branch lines 2 are parallel to the conveying main line 1, thereby greatly improving space utilization and reducing unnecessary occupied area caused by too many conveying branch lines.
[0019] Reference Figure 2 As shown, the main conveying line 1 includes a high-speed conveying section 11, a medium-speed conveying section 12, a low-speed conveying section 13, and a queuing conveying section 14, which are connected to each other. In this embodiment, the high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 preferably use a belt conveyor, and the queuing conveying section 14 preferably uses a roller conveyor, so that the high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 can sequentially send the packages to the queuing conveying section 14 at a uniform speed, and the queuing conveying section 14 controls the conveying speed of the packages according to the set value of the package spacing, so that the queuing conveying section 14 can transport the packages at a certain distance, so that more packages can be cached, which has a caching effect.
[0020] In this embodiment, the structures and principles of the high-speed conveying section 11, the medium-speed conveying section 12, the low-speed conveying section 13, and the queuing conveying section 14 are existing technologies and will not be repeated here.
[0021] It is further explained that the high-speed conveying section 11, the medium-speed conveying section 12, and the low-speed conveying section 13 in this embodiment adopt a multi-stage deceleration method, that is, the transmission speed changes from high speed to low speed, so as to ensure that the package can transition smoothly during the transportation process and realize efficient and safe transportation of the package.
[0022] Combination Figure 2 , Figure 3 As shown, a transition plate 111 is provided at the input end of the high-speed conveying section 11, and a second inclined bracket 112 is provided on one side of the high-speed conveying section 11. A plurality of power rollers 113 are rotatably provided between the second inclined bracket 112, the high-speed conveying section 11 and the transition plate 111, so that an integrated design is formed between the plurality of power rollers and the high-speed conveying section 11, thereby reducing the gap between the two, and the angle between the axis of the power roller 113 and the high-speed conveying section 11 is 30°-60°, preferably 45°, so as to avoid the high-speed package from rolling after deceleration and stalling, and a power drive device is fixedly installed on the second inclined bracket 112. In this embodiment, a servo motor is preferably used, and its output shaft is transmission-connected with the plurality of power rollers 113, so that after the parcels of the parcel sorting line pass through the plurality of power rollers 113, the power drive device drives the plurality of power rollers 113 to rotate and deliver the parcels to the high-speed conveying section 11, thereby avoiding the rolling caused by the change of the parcel shape when the parcel transitions vertically.
[0023] Reference Figures 4 - 7As shown in the figure, further, the confluence device 5 includes a plurality of rollers 51, a plurality of rollers 52, and a driving device 53. A first inclined bracket 121 is provided on one side of the medium-speed conveying section 12, so that one end of the plurality of rollers 51 is rotatably connected to the first inclined bracket 121, and the other end is rotatably connected to the side wall of the medium-speed conveying section 12, thereby forming an integrated design between the plurality of rollers 51 and the medium-speed conveying section 12, reducing the gap between the two, and at the same time the structure is simpler, effectively reducing the equipment cost. The plurality of rollers 52 are respectively rotatably arranged on the first inclined bracket 121 along the length direction, and the driving device 53 is fixedly installed on the outside of the first inclined bracket 121. In this embodiment, the driving device 53 is preferably a reduction motor, and a belt pulley is fixedly installed on its output shaft. A driving belt 54 is tensioned between the plurality of rollers 52 and is in transmission connection with the driving device 53, and the surface of the driving belt 54 abuts against the plurality of rollers 51, so that when the driving device 53 drives the driving belt 54 to rotate, the rollers 52 are driven to rotate by the friction force on the surface of the driving belt 54, thereby merging the packages on the conveying branch line 2 onto the medium-speed conveying section 12, so that the packages on the conveying branch line 2 are confluent with the packages on the conveying main line 1.
[0024] It should be further noted that in this embodiment, the plurality of rollers 52 are divided into two groups, and each group is sleeved with a driving belt 54. A linkage shaft 55 is rotatably arranged between the first inclined bracket 121 and the medium-speed conveying section 12, and the end parts of the linkage shaft 55 are respectively in transmission connection with the two groups of driving belts 54, so as to stagger the two groups of driving belts 54 by using the linkage shaft 55 to ensure that the driving belt 54 can abut against each roller 51. When the driving device 53 drives one group of driving belts 54 to rotate, the linkage shaft 55 drives the other group of driving belts 54 to rotate under the drive of this driving belt 54, greatly improving the stability of the confluent transmission.
[0025] Preferably, a first package detection module is provided at the input end of the medium-speed conveying section 12, and a second package detection module is provided at the confluence of the confluence device 5 and the medium-speed conveying section 12. In this embodiment, the first package detection module and the second package detection module are preferably photoelectric sensors. The first package detection module is used to monitor whether there is a package at the input end of the medium-speed conveying section 12, and the second package detection module is used to detect whether the package reaches the specified position. When the second package detection module detects the package on the confluence device 5 and feeds it back to the PLC unit, if the first package detection module detects that there is no package at the input end of the medium-speed conveying section 12 at this time, the confluence device 5 will merge the package onto the medium-speed conveying section. If the first package detection module detects that there is a package passing through the input end of the medium-speed conveying section 12, the confluence device 5 will wait for a set time and then send the package on the conveying branch line 2 onto the medium-speed conveying section 12, so as to avoid the collision between the package on the confluence device 5 and the package on the conveying main line 1 and prevent the package from being damaged.
[0026] The connection relationships between the above PLC unit, the first package detection module, the second package detection module, and each conveying section are prior art, and are not described repeatedly in this embodiment.

In this embodiment, the rolling deviation rectification part 32 includes a first deviation rectification roller group and a second deviation rectification roller group. The first deviation rectification roller group and the second deviation rectification roller group are in a V shape and are in contact with the lower belt 120 of the medium-speed conveying section 12, so as to rectify the belt on the medium-speed conveying section 12 by the rolling deviation rectification part 32, avoid the situation of belt deviation on the medium-speed conveying section 12, and improve the conveying efficiency and conveying safety.
[0028] Specifically, the first deviation rectification roller group includes a first deviation rectification roller 321, and the second deviation rectification roller group includes a second deviation rectification roller 322. The first deviation rectification roller 321 and the second deviation rectification roller 322 are respectively rotatably arranged on the deviation rectification bracket 31, and the first deviation rectification roller 321 and the second deviation rectification roller 322 are not parallel to each other. In this embodiment, the included angle between the first deviation rectification roller 321 and the second deviation rectification roller 322 is 28°-32°, preferably 30°. Moreover, both the first deviation rectification roller 321 and the second deviation rectification roller 322 are in contact with the lower surface of the belt of the medium-speed conveying section 12, so that the first deviation rectification roller 321 and the second deviation rectification roller 322 rotate under the drive of the belt of the medium-speed conveying section 12, thereby using the first deviation rectification roller 321 and the second deviation rectification roller 322 to continuously squeeze the belt of the medium-speed conveying section 12 towards the middle, so as to avoid the situation of belt deviation towards both sides during the conveying process of the belt on the medium-speed conveying section 12, realize the automatic deviation rectification of the medium-speed conveying section 12, and greatly improve the stability of package conveying.
[0029] Referring to Figure 12 、 Figure 13 As shown, more preferably, a plurality of side plates 131 are provided on both sides of the low-speed conveying section 13. Each pair of side plates 131 are fixedly connected by a connecting block 1312, and a plurality of reinforcing plates 1311 are sequentially arranged at intervals on the surface of the side plates 131 along the conveying direction of the package. Thus, the fuselage strength of the low-speed conveying section 13 is greatly enhanced, the load-bearing capacity of a large span is realized, the space utilization efficiency is effectively improved, and the difficulty and intensity of the installation work are greatly reduced.
[0030] Referring toFigure 12 , Figure 14 As shown, further, a horizontal conveyor 15 is provided at the output end of the low-speed conveying section 13. In this embodiment, the horizontal conveyor 15 and the low-speed conveying section 13 are both composed of a belt, a plurality of transmission shafts, and a driving motor.

In order to ensure that the transmission speed of the horizontal conveyor is consistent with the transmission speed of the low-speed conveying section 13, in this embodiment, a first synchronous wheel 132 is provided on the transmission shaft of the low-speed conveying section 13, and a second synchronous wheel 153 is provided on the transmission shaft of the horizontal conveyor 15. A connecting belt 151 is connected to the first synchronous wheel 132 and the second synchronous wheel 153 in transmission connection, and a tensioning belt 153 is fixedly installed between the side wall of the low-speed conveying section 13 and the horizontal conveyor 15. Bracket 154, a tensioning slide 155 can be raised and lowered below the tensioning bracket 154, wherein a strip groove is opened on the side wall of the tensioning slide 155, and a connecting hole is set on the side wall of the tensioning bracket 154, and the strip groove of the tensioning slide 155 is fixedly connected with the connecting hole of the tensioning bracket 154 by a locking component. In this embodiment, the locking component preferably adopts screws and nuts to make the height of the tensioning slide 155 adjustable, and a tensioning wheel 152 is rotatably set at the bottom of the tensioning slide 155, and the tensioning wheel 152 is in conflict with the connecting belt, so that the tensioning wheel 152 is driven to rise and fall through the tensioning slide 155, so as to adjust the tightness of the connecting belt 151, thereby ensuring that the linkage between the horizontal conveyor 14 and the low-speed conveying section 13 is more stable.
[0031] Further preferably, in the present embodiment, a centering roller machine 141 is provided between the queuing conveying section 14 and the horizontal conveying section 15, so that the centering roller machine 141 can center the parcels sent out from the horizontal conveying section 15 onto the queuing conveying section 14, so that the parcels can be arranged in a straight line and sent to the queuing conveying section 14, thereby ensuring neat and orderly transportation of the parcels.
[0032] Reference Figure 10 , Figure 15 As shown, further, a transition frame 132 is fixedly provided at the input end of the low-speed conveying section 13. In this embodiment, the cross-section of the transition plate matches the shape of the gap between the low-speed conveying section 13 and the medium-speed conveying section 12, so as to solve the problem that after the low-speed conveying section is installed tilted, the gap between the low-speed conveying section 13 and the medium-speed conveying section 12 is too large, or the centers of the two are not parallel, so as to avoid the package falling out of the conveying main line 1 from the gap due to the large gap between the two. At the same time, in order to avoid the package from being stuck in the gap between the low-speed conveying section 13 and the medium-speed conveying section 12, a transition roller 1321 is rotatably provided on the transition frame 132 in this embodiment, so that the package can be smoothly delivered from the medium-speed conveying section 12 to the low-speed conveying section, so as to prevent the package from being stuck or blocked.
