Description

Technical Field

[0001] The present invention relates to the technical field of express delivery sorting, and in particular to an intelligent express delivery sorting system. Background Art

[0002] With the popularity of online shopping, the volume of express delivery sorting business continues to increase. In order to improve sorting efficiency, most logistics companies will use intelligent express delivery sorting systems to automatically sort express deliveries. In this sorting process, in order to allocate different express deliveries to different sorting ports, sorting machines are generally used to distribute the express deliveries. Among them, the most common one is the O-belt pendulum wheel sorting machine, which is widely used in this field due to its low maintenance cost and flexible use.

[0003] When in use, the existing O-belt balance wheel sorter is mainly used for express parcels within a certain weight range because of its fixed output force. However, in actual situations, the weights of some express parcels vary. In order to improve efficiency, logistics companies will set the transmission speed of the conveyor belts of express parcels to be faster. As a result, some heavier express parcels will pass through the balance wheel sorter due to their excessive inertia when passing through the balance wheel sorter, missing the correct sorting port and affecting the sorting accuracy.

[0004] Therefore, in order to balance sorting efficiency and ensure that heavier express parcels can accurately enter the correct sorting port, an intelligent express sorting system is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an intelligent express sorting system, which solves the problem that some heavier express items will miss the correct sorting port due to the excessive inertia of the express items when passing through the balance wheel sorting machine. The express items are initially decelerated by driving the deceleration component and the deceleration wheel, and the balance wheel sorting device is tilted to slow down the express items and enable them to be stably transported by the balance wheel sorting machine, thereby avoiding the situation where the express items miss the sorting port due to the excessive inertia of the express items.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] An intelligent express sorting system, comprising a swing wheel sorting device, a weight detection device, a support frame, a partition board, and further comprising a speed reduction component, a support component, an adjustment component, a speed reduction wheel, a cam, a connecting plate, a stepless speed change wheel two, and a driving motor. The speed reduction component is located in front of the swing wheel sorting device, the weight detection device is located in front of the speed reduction component, the support frame is connected to the rear top position on the side of the swing wheel sorting device through a bearing, the adjustment component is located at the bottom of the swing wheel sorting device, the support component is located at the bottom of the adjustment component, the speed reduction wheel is located between the swing wheel sorting device and the speed reduction component, the cam is located at the bottom of the speed reduction component, the driving motor is in transmission connection with the cam. The weight detection device detects the weight of the express item and drives the cam to rotate through the driving motor, and the rotation amplitude of the driving motor driving the cam is proportional to the weight of the express item. The driving motor drives the cam to press down the adjustment component and adjusts the counterclockwise tilt angle of the swing wheel sorting device with the connection point between the swing wheel sorting device and the support frame as the axis and the position of the speed reduction wheel in direct proportion to the driving amplitude of the driving motor. The direction in which the express item is conveyed is the front.

[0008] In the above solution, the weight of the express item is detected by the weight detection device to control the driving motor to drive the cam and adjust the deceleration force of the device. The rotation of the cam will control the tightening of the first transmission belt and adjust the position of the support plate. The tightening of the speed reduction wheel adjusts the rotation ratio between the first stepless speed change wheel and the second stepless speed change wheel, and the speed is reduced by the direction rotation of the speed reduction wheel, which can effectively improve the stability of express delivery. At the same time, it is flexibly adjusted according to the weights of different express items to ensure the accuracy of express item delivery.

[0009] Preferably, the deceleration assembly includes a speed bump, a transmission shaft, a connecting member, a sleeve, a pressing rod, a pushing rod, a first continuously variable pulley, a first transmission belt, a central shaft, a first gear, a second transmission belt and a second gear. The speed bump is located above the cam and in front of the pendulum sorting device. The surface of the speed bump is provided with rubber protrusions. The transmission shafts are distributed inside the speed bump, and the connecting member is connected to the part of the transmission shaft close to the inner edge of the speed bump. The two transmission shafts near the front and back are sleeved with the speed bump. The sleeve and the pushing rod are connected to the connecting member at a position close to the inner side of the speed bump by bearings. The first continuously variable pulley is located in the middle of the pushing rod. The first transmission belt is located outside the transmission shaft. The central shaft is located in the middle of the first continuously variable pulley and is connected to the first continuously variable pulley by bearings. The central shaft is connected to the partition plate. The first gear is located behind the first continuously variable pulley and is connected to the partition plate by bearings. Belt pulleys are installed on the middle of the first continuously variable pulley and the surface of the first gear, and the second transmission belt is sleeved on the belt pulleys on the surfaces of the first continuously variable pulley and the first gear. The thickness of the belt pulley on the first gear is 1.5 times the thickness of the belt pulley on the first continuously variable pulley. The pressing rod is installed inside the sleeve. A connecting plate is fixedly installed at a position near the top of the outer surface of the cam. The top of the connecting plate is connected to the transmission shaft in the middle of the inner side of the speed bump by bearings. The pressing rod is sleeved inside the sleeve. The first springs are distributed at both ends of the pressing rod and inside the sleeve. The pushing rod is located on the side of the sleeve away from the speed bump. The rotation ratio adjustment between the first continuously variable pulley and the second continuously variable pulley mainly relies on the middle part of the connecting member to contract in the middle to squeeze the collar on the first continuously variable pulley. By squeezing the auxiliary spring on the first continuously variable pulley through the collar, the struts on the collar are opened to adjust the position of the moving shaft on the first continuously variable pulley, so that the moving shafts on the first continuously variable pulley spread out. At the same time, the moving shaft on the third spring below is squeezed by the third transmission belt. In this way, the rotation ratio is adjusted. The second continuously variable pulley has the same structure as the first continuously variable pulley, and springs are provided in the middle of both the second continuously variable pulley and the first continuously variable pulley. A third transmission belt is sleeved in the middle of the second continuously variable pulley and the first continuously variable pulley. The weight detection device is connected to the drive motor by telecommunications.

[0010] In the above solution, the tightness of the speed bump is adjusted by the rotation of the cam. At the same time, according to the weight of the express item, the rotation ratio is adjusted by the first continuously variable pulley and the second continuously variable pulley, so that when the express item passes through the speed bump, the deceleration wheel is driven by the transmission on the deceleration assembly to rotate in the reverse direction, so as to decelerate the heavier express item and ensure the stable movement of the express item.

[0011] Preferably, the support assembly includes support columns, a support plate, a first limiting groove, a sliding groove, and a second spring. The support columns are distributed on the left and right sides of the pendulum wheel sorting device. The first limiting groove and the sliding groove are both formed on one side of the support column close to the adjustment assembly. The first limiting groove is located in the middle of the sliding groove. The second spring is sleeved inside the sliding groove. The support plate is slidably connected to the sliding groove.

[0012] In the above solution, the support assembly supports the adjustment assembly through the second spring. The upper part of the support assembly is attached to the bottom of the pendulum wheel sorting device, so that the support assembly jacks up the adjustment assembly and tightly fits with the bottom of the cam, facilitating the adjustment of the position of the adjustment assembly by the cam and facilitating the adjustment of the inclination degree of the pendulum wheel sorting device, ensuring effective deceleration of the express items and stable transportation.

[0013] Preferably, the adjustment assembly includes a support plate, sliding wheels, limiting rods, and connecting blocks. The support plate is located at the bottom of the pendulum wheel sorting device. The sliding wheels are distributed on the left and right sides of the support plate and are also distributed at the bottom of the pendulum wheel sorting device. The sliding wheels are connected to the support plate by bearings. The limiting rods and the connecting blocks are movably installed on the left and right sides of the support plate. The first gear meshes with the second gear. A second limiting groove is formed at a position of the partition plate close to the connecting rod. The second limiting groove is an arc-shaped groove presenting the outer shape of the revolution trajectory of the connecting rod around the first gear. Connecting rods are connected to the left and right sides of the deceleration wheel. The second gear is sleeved on the outer surface of the connecting rod. The connecting block is sleeved on the outer side of the connecting rod and is connected by a bearing. The bottom of the pendulum wheel sorting device is arc-shaped.

[0014] In the above solution, the upper part of the sliding wheel is attached to the bottom of the pendulum wheel sorting device. When adjusting the height of the support plate by the cam, the bottom of the pendulum wheel sorting device can move on the sliding wheel, conveniently adjusting the inclination angle of the pendulum wheel sorting device. At the same time, according to the height of the support plate, the connecting block drives the connecting rod to move in the second limiting groove. The adjustment of the position of the connecting block driving the connecting rod can enable the deceleration wheel to play a certain supporting role after the pendulum wheel sorting device is tilted, avoiding the situation that the express item collides with the pendulum wheel on the pendulum wheel sorting device or the surface of the pendulum wheel sorting device during the movement of the express item. While ensuring the meshing of the first gear and the second gear, it is convenient for the express item to drive the deceleration belt according to the inertia of the express item after moving onto the deceleration belt, and through the transmission components in the deceleration assembly, drive the second gear to rotate to further decelerate the express item.

[0015] Preferably, two protrusions are integrally formed on the outer side of the cam. The protrusion on the top of the cam is sleeved inside the first transmission belt through an external rotating shaft, and the left and right sides of the protrusion on the top of the cam are connected to the second stepless speed change wheel. The protrusion on the side of the cam close to the bottom fits on the top of the support plate.

[0016] In the above scheme, the cam adopts a special-shaped part, and the central part is connected to the drive motor for transmission. The drive motor is fixed to the weight detection equipment through a fixing component to ensure the stable operation of the drive motor. The top and side are convex, and the upper convexity is connected to the rotating shafts on the left and right sides, connected through bearings, and the rotating shaft is connected to the continuously variable wheel 2 and the transmission belt 1. The convexity on the side of the cam fits with the top of the support plate. In this way, it can be easily adjusted through the drive motor, which is convenient for the equipment to be adjusted according to express items of different weights.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention drives the motor to drive the rotation of the cam to adjust the deceleration component and the adjustment component. The adjustment of the deceleration component improves the deceleration effect of the deceleration belt and the deceleration wheel. The adjustment of the adjustment component increases the inclination of the balance wheel sorting device. The express is decelerated by its own weight through inclination, thereby preventing the express from passing through the balance wheel sorting device too quickly. At the same time, the adjustment component adjusts the position of the deceleration wheel, and adjusts the position of the deceleration wheel according to the inclination of the balance wheel sorting device. When the express moves to the deceleration wheel through the deceleration component, it plays a cushioning role for the express, thereby preventing the express from colliding with the balance wheel sorting device due to excessive inclination, thereby affecting the stability of the express.

[0019] 2. The present invention sets a deceleration component and pulls the transmission belt 1 through the rotation of the cam, so as to adjust the transmission ratio of the continuously variable speed wheel 1 and the continuously variable speed wheel 2, so that the heavier the express is, the greater the resistance it encounters when passing through the deceleration belt. At the same time, the setting of the deceleration belt also plays a certain buffering role for the balance wheel sorting equipment, preventing the express items from contacting the balance wheel sorting equipment too quickly due to inertia, thereby ensuring the stability of express sorting.

[0020] 3. The present invention provides an adjustment component, and adjusts the height of the adjustment component by rotating the cam. When one end of the balance wheel sorting device is fixed by a support frame, the height of the adjustment component is adjusted, and the inclination angle of the balance wheel sorting device can be adjusted. When the express package is moved onto the balance wheel sorting device and is tilted, the express package can be slowed down by its own weight, and stably transported by the balance wheel on the balance wheel sorting device, thereby improving the stability of the equipment transportation and avoiding the situation where the express package misses the sorting port.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 8 , the present invention provides an intelligent express sorting system, and the technical solutions are as follows:

[0032] An intelligent express sorting system includes a swing wheel sorting device 1, a weight detection device 3, a support frame 4, a partition plate 7, and also includes a speed reduction assembly 2, a support assembly 5, an adjustment assembly 6, a speed reduction wheel 8, a cam 9, a connecting plate 12, a stepless variable speed wheel two 13, and a driving motor 14. In the speed reduction assembly 2, it includes a speed reduction belt 201, a transmission shaft 202, a connecting piece 203, a sleeve 204, a pressing rod 205, a pushing rod 206, a stepless variable speed wheel one 207, a transmission belt one 208, a central shaft 209, a gear one 210, a transmission belt two 211, and a spring one 212. In the support assembly 5, it includes a support column 501, a support plate 502, a first limit groove 503, a sliding groove 504, and a spring two 505. In the adjustment assembly 6, it includes a support plate 601, a sliding wheel 602, a limit rod 603, and a connecting block 604.

[0033] As an implementation mode of the present invention, referring to Figure 1 and Figure 5 , the speed reduction assembly 2 is located in front of the swing wheel sorting device 1, the weight detection device 3 is located in front of the speed reduction assembly 2, the adjustment assembly 6 is located at the bottom of the swing wheel sorting device 1, the support assembly 5 is located at the bottom of the adjustment assembly 6, the speed reduction wheel 8 is located between the swing wheel sorting device 1 and the speed reduction assembly 2, the cam 9 is located at the bottom of the speed reduction assembly 2, the driving motor 14 is in transmission connection with the cam 9. After the weight detection device 3 detects the express and its weight, it will drive the cam 9 to rotate through the driving motor 14, adjust the positions of the swing wheel sorting device 1 and the speed reduction wheel 8 by pressing down the adjustment assembly 6, and the speed reduction assembly 2 rotates in the opposite direction in cooperation with the speed reduction wheel 8 and cooperates with the overall inclination of the swing wheel sorting device 1 to decelerate and convey the express. Two protrusions are integrally formed on the outer side of the cam 9. The protrusion on the top of the cam 9 is sleeved on the inner side of the transmission belt one 208 through an external rotating shaft, and the left and right sides of the protrusion on the top of the cam 9 are connected to the stepless variable speed wheel two 13. The protrusion near the bottom on the side of the cam 9 fits on the top of the support plate 601. Because the weight applied by the swing wheel sorting machine has a certain range, and some heavier express deliveries will have a large inertia after being conveyed at high speed by the front transmission belt, resulting in the express delivery itself having a large inertia and possibly quickly passing through the swing wheel sorting device 1 without making sufficient contact with the swing wheels on the swing wheel sorting device 1, leading to the situation where the express delivery misses the sorting port. However, the present invention adopts a multiple deceleration method to reduce the inertia of the express delivery itself and, according to the weight of the express delivery itself, improve the deceleration effect to different degrees, avoiding the situation where the express delivery stops and blocks the equipment.

[0034] As an implementation mode of the present invention, referring to Figures 2 to 4, the support columns 501 are distributed on the left and right sides of the pendulum sorting device 1. The first limiting groove 503 and the sliding groove 504 are both opened on the side of the support column 501 close to the adjusting assembly 6. The first limiting groove 503 is located in the middle of the sliding groove 504. The second spring 505 is sleeved inside the sliding groove 504. The support plate 502 is slidably connected to the sliding groove 504. The support plate 601 is located at the bottom of the pendulum sorting device 1. The sliding wheels 602 are distributed on the left and right sides of the support plate 601 and are also distributed at the bottom of the pendulum sorting device 1. The sliding wheels 602 are connected to the support plate 601 by bearings. The limiting rods 603 and the connecting blocks 604 are installed on the left and right sides of the support plate 601. The left and right sides of the reduction gear 8 are connected with connecting rods 10. A second gear 11 is sleeved on the outer surface of the connecting rod 10. The connecting block 604 is sleeved on the outside of the connecting rod 10 and is connected by a bearing. The support frame 4 is connected to the pendulum sorting device 1. The bottom of the pendulum sorting device 1 is arc-shaped. The first gear 210 meshes with the second gear 11. And a second limiting groove 15 is opened at the position of the partition plate 7 close to the connecting rod 10. The second limiting groove 15 is an arc-shaped groove presenting the outer shape of the revolution track of the connecting rod 10 around the first gear 210. The support assembly 5 provides support for the adjusting assembly 6 and enables the adjusting assembly 6 to have a certain adjustment space when being extruded by the cam 9, which is convenient for adjusting the inclination state of the pendulum sorting device 1. At the same time, the adoption of the sliding wheels 602 in the adjusting assembly 6 can change the contact between the adjusting assembly 6 and the pendulum sorting device 1 into rolling friction, reduce the friction between the bottom of the pendulum sorting device 1 and the support plate 601, and improve the smoothness of the pendulum sorting device 1 when tilting. At the same time, the tilting angle of the pendulum sorting device 1 is limited between zero degree and five degrees. By moving the limiting rod 603 in the first limiting groove 503, the moving track of the adjusting assembly 6 is kept in a vertical state. The connecting block 604 adjusts the connecting rod 10. A flexible gasket is arranged at the part where the connecting block 604 contacts the connecting rod 10 to ensure that the connecting rod 10 can move stably in the second limiting groove 15. At the same time, the flexible gasket between the connecting block 604 and the connecting rod 10 is connected to the connecting rod 10 by a bearing to prevent the flexible gasket from affecting the rotation of the connecting rod 10 and the reduction gear 8.

[0035] As an implementation manner of the present invention, refer to Figures 6 to 8, the speed bump 201 is located above the cam 9. The drive shaft 202 is distributed inside the speed bump 201, and the connecting member 203 is connected to the part of the drive shaft 202 close to the inner edge of the speed bump 201. The sleeve 204 and the push rod 206 are connected to the connecting member 203 at a position close to the inner side of the speed bump 201 by bearings. The continuously variable transmission wheel one 207 is located in the middle of the push rod 206. The transmission belt one 208 is located outside the drive shaft 202. The central shaft 209 is located in the middle of the continuously variable transmission wheel one 207, and the central shaft 209 is connected to the continuously variable transmission wheel one 207 by bearings. The central shaft 209 is connected to the partition plate 7. The gear one 210 is located behind the continuously variable transmission wheel one 207, and the gear one 210 is connected to the partition plate 7 by bearings. Belt pulleys are installed on the middle part of the continuously variable transmission wheel one 207 and the surface of the gear one 210, and the transmission belt two 211 is sleeved on the belt pulleys on the surfaces of the continuously variable transmission wheel one 207 and the gear one 210. The extrusion rod 205 is installed inside the sleeve 204, and the extrusion rod 205 is sleeved inside the sleeve 204. The first springs 212 are distributed at both ends of the extrusion rod 205, and the first springs 212 are distributed inside the sleeve 204. The push rod 206 is located on the side of the sleeve 204 away from the speed bump 201. A connecting plate 12 is installed at a position close to the top on the outer surface of the cam 9. The top of the connecting plate 12 is sleeved with the drive shaft 202 in the middle of the inner side of the speed bump 201. The continuously variable transmission wheel two 13 has the same structure as the continuously variable transmission wheel one 207, and the third springs 17 are provided in the middle of both the continuously variable transmission wheel two 13 and the continuously variable transmission wheel one 207. A transmission belt three 16 is sleeved in the middle of the continuously variable transmission wheel two 13 and the continuously variable transmission wheel one 207. The weight detection device 3 is connected to the drive motor 14 by telecommunication. The speed bump 201 is driven by the inertia of the express item itself. At this time, the cam 9 drives the rotating shaft connected to the cam 9 to rotate, so that the rotating shaft pulls the transmission belt one 208, and pulls the speed bump 201 through the connecting plate 12, so that the drive shaft 202 is pressurized through the connecting member 203 to adjust the transmission ratios of the continuously variable transmission wheel one 207 and the continuously variable transmission wheel two 13. The heavier the express item is, the greater the resistance for the express item to move on the speed bump 201 is, ensuring that the inertia of the express item is reduced and stable transportation can be carried out.

[0036] Working principle: After the weight detection device 3 detects the weight of the express item and conveys the weight information to the driving motor 14, the driving motor 14 adjusts the rotation amplitude of the cam 9 according to the weight information. After the cam 9 rotates, it drives the speed reducer belt 201 and the first transmission belt 208 to tighten, and adjusts the transmission ratio between the first continuously variable pulley 207 and the second continuously variable pulley 13, improving the deceleration effect of the speed reducer belt 201 on the express item. At the same time, it drives the deceleration wheel 8 to rotate in the reverse direction through component transmission to further decelerate the express item, and the deceleration wheel 8 plays a supporting role. Moreover, after the cam 9 rotates, it squeezes the adjustment component 6, and the downward movement of the adjustment component 6 drives the inclination of the swing wheel sorting device 1, further improving the deceleration effect on the express item and ensuring that the express item can be stably conveyed by the swing wheels on the swing wheel sorting device 1.

[0037] Specifically, after the weight detection device 3 detects the weight of the express item and conveys the weight information to the driving motor 14, the driving motor 14 adjusts the rotation amplitude of the cam 9 according to the weight information. When the cam 9 rotates, due to the shape of the cam 9 itself, it will drive the position adjustment of the rotating shafts on both the left and right sides of the cam 9, drive the first transmission belt 208 to tighten, and at the same time drive the speed reducer belt 201 to tighten through the connecting plate 12. Moreover, the cam 9 will also press down the adjustment component 6, adjust the height of the adjustment component 6, and cause the swing wheel sorting device 1 to tilt.

[0038] Among them, after the cam 9 drives the first transmission belt 208 and the speed reducer belt 201 to tighten, the distance between the transmission shafts 202 sleeved with the speed reducer belt 201 in the speed reducer belt 201 will be reduced, causing the connecting piece 203 to drive the sleeve 204 to squeeze the extrusion rod 205. At the same time, the connecting piece 203 will squeeze the push rod 206. After the push rod 206 is squeezed, it will squeeze the first continuously variable pulley 207, causing the moving shaft on the first continuously variable pulley 207 to move towards the edge, presenting an overall open state, and squeezing the moving shaft on the third spring 17, causing the moving shaft on the third spring 17 to contract, changing the rotation ratio between the two.

[0039] Among them, the cam 9 presses down the support plate 601. The support plate 601 is erected on the support plate 502, and the limit rod 603 moves in the first limit groove 503, causing the support plate 502 to squeeze the second spring 505. Moreover, the downward movement of the support plate 601 causes the part of the swing wheel sorting device 1 close to the front to tilt downward under the restriction of the support frame 4. The lower part of the swing wheel sorting device 1 slides on the sliding wheel 602. At the same time, the connecting block 604 drives the position adjustment of the connecting rod 10. The connecting rod 10 is restricted by the second limit groove 15, ensuring that the second gear 11 always meshes with the first gear 210. At the same time, the position of the deceleration wheel 8 changes according to the inclination degree of the swing wheel sorting device 1.

[0040] After the express parcel moves onto the speed bump 201, the inertia of the express parcel itself drives the speed bump 201 to rotate. The speed bump 201 drives the transmission shaft 202 to rotate. The transmission shaft 202 drives the first transmission belt 208 to rotate. The first transmission belt 208 drives the rotating shafts on both the left and right sides of the cam 9 to rotate, and drives the second continuously variable pulley 13 to rotate. The second continuously variable pulley 13 drives the first continuously variable pulley 207 to rotate through the third transmission belt 16. The first continuously variable pulley 207 drives the second transmission belt 211. The second transmission belt 211 drives the first gear 210 to rotate. The first gear 210 meshes with the second gear 11, thereby driving the second gear 11 to rotate in the reverse direction, and decelerating the express parcel through the reverse rotation of the second gear 11. And through the position of the deceleration wheel 8, a supporting effect is achieved on the express parcel, avoiding the situation that the express parcel collides with the swing wheel sorting device 1 and is prone to flipping. After the express parcel stably moves onto the swing wheel sorting device 1, the express is further decelerated by the inclination of the swing wheel sorting device 1, and then stably conveyed by the swing wheels on the swing wheel sorting device 1. After the conveying is completed, the driving motor 14 drives the cam 9 to return to its original position. The first spring 212 drives the speed bump 201 and the first transmission belt 208 to reset. At the same time, the second spring 505 drives the adjusting assembly 6 to reset.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
