Description

Technical Field

[0001] The present invention belongs to the technical field of express logistics sorting, and specifically relates to a high-efficiency three-dimensional cross-type express logistics sorting device. Background Art

[0002] Express logistics is used to transfer and transport goods in warehouses by various means of transportation and deliver them to recipients. When sorting goods, express logistics sorting devices are generally required, and the goods are sorted in a three-dimensional cross-type according to their weight, that is, goods of different weights are sorted to corresponding positions accordingly, so as to facilitate transportation and warehousing; in the prior art, for example, an invention patent with patent number CN202210531710.1 discloses a "highly efficient intelligent three-dimensional cross-type express logistics sorting device", which uses a spring to elastically support one end of a conveyor belt for transportation, so that express goods of different weights generate different gravity when placed on it, and uses compressed springs to The spring produces different downward displacements and corresponds to different sorting tracks. This design has some defects: since the conveyor belt is designed to rotate downward, only one express can be placed on it at a time, which seriously restricts the efficiency of express sorting. In addition, this design of sorting by the weight of a single express requires the conveyor belt as a whole to apply a large force to the spring (not only the weight of the goods itself, but also the weight of the conveyor belt). Each time the spring is pressurized, it will be subject to the additional inertial impact force generated by the above weight under the acceleration of gravity. The spring may actually be compressed to the limit under the action of a heavy object. Over time, the spring will fatigue or even fail, so it is urgently needed to be improved.

[0009] As a preferred solution of the present invention, the clamping ring can drive the clamping column to rotate 20° upward around the axis of the pillar, and can make the outer surface of the clamping column abut against the top of the inner wall of the clamping groove.

[0010] As a preferred solution of the present invention, the first discharge plate, the second discharge plate and the third discharge plate are all in contact with the outer surface of the sorting barrel, and the plane of the first discharge plate is coplanar with the bottom of the sorting slot.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. This device has been redesigned to achieve efficient express cargo sorting function. It is provided with a pillar and two groups of sorting cylinders are rotatably installed on its outer surface. The express cargo is received through the sorting slot opened inside the sorting cylinder and is ready for sorting. A connecting ring and a fixed block 1 fixedly installed at one end of the sorting cylinder and a fixed block 2 fixed on the outer surface of the pillar are provided. Two groups of springs 1 are inserted between the fixed block 1 and the fixed block 2. When the sorting cylinder rotates, one group of springs 1 is compressed and one group of fixed blocks 2 is stretched, generating Two sets of rebound forces, through the express goods falling on the surface of the sorting slot, and use its weight to drive the sorting cylinder to rotate as a whole. The greater the rotation angle of the sorting cylinder, the greater the pressure on spring one, that is, the heavier the goods are. The rotation displacement of the sorting cylinder generated when spring one is compressed is used to guide the express goods from light to heavy to discharge plate one, discharge plate two and discharge plate three at a time. This design not only reduces the force on spring one and extends its service life, but also avoids the entire weight of the workbench acting on spring one, making the sorting efficiency of the device higher.

[0016] 2. At the same time, the device is also provided with a clamping ring which is slidably installed on the outer surface of the pillar, fixed to the outermost side of the outer surface of the pillar by a fixing ring, and the clamping ring is used to compress the clamping ring, and the clamping column is driven to be clamped into the inside of the clamping slot by the clamping ring. When heavy goods fall on the sorting slot, the goods are sensed by the grating, and the signal is sent to the controller, so that the controller controls the electromagnet to be energized 1 to 3 seconds after the goods leave the conveyor belt, and then quickly cut off the power. The purpose of this design is that the heavy goods will drive the sorting cylinder to rotate quickly, and when the goods move to the discharge slot, the sorting cylinder will rotate quickly. When the second plate or the third discharge plate is aligned, rotation over-position phenomenon will occur, that is, the sorting slot is not coplanar with the second and third discharge plates, which affects the discharge of goods from the sorting slot. The sorting cylinder rotates rapidly and drives the sorting slot to rotate to a horizontal state. At this time, the clamping column just abuts against the top of the inner wall of the clamping slot, thereby eliminating the inertia force generated by the heavier goods. Subsequently, the electromagnet can be energized and absorb the permanent magnet, the clamping ring and the clamping column, so that the connecting ring loses the limit of the clamping column and moves down freely. This design not only ensures the stability of sorting and discharging, but also protects the spring from being over-pressurized.

[0017] 3. The device is also designed with two groups of sorting barrels, which cooperate with the fixed column, sleeve, limit plate 1, limit plate 2 and limit plate 3, so that the two groups of sorting barrels can work alternately to complete express sorting. By setting limit plate 1, limit plate 2 and limit plate 3, which are equidistantly distributed on the outer surface of the sleeve and are integrated with the sleeve, when the express goods pass through limit plate 1, it will push limit plate 2 or limit plate 3 to rotate. At this time, limit plate 1 will be driven by the sleeve to the side close to the express goods, forming an inclined limit. When the next express goods arrive, the inclined limit plate 1 will move the express goods to the other side of the previous express goods, and this cycle is repeated, giving the two groups of sorting barrels time to return to their original positions each time, greatly improving the working efficiency of the device.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, the embodiment of the present invention provides a highly efficient three-dimensional cross-type express logistics sorting device, including a workbench 1, a motor 2, a transport roller 3 and a conveyor belt 4, and also includes a sorting platform 12 installed on the right side of the bottom of the workbench 1, a controller is installed on the top of the sorting platform 12, a pillar 13 is fixedly installed in the middle of the sorting platform 12, and two groups of sorting cylinders 14 symmetrically distributed front and back are rotatably installed on the outer surface of the pillar 13, and a sorting slot 15 is opened inside the sorting cylinder 14, and the sorting slot 15 penetrates to the outer surface of the sorting cylinder 14 to the lower right, and the bottom of the sorting slot 15 forms an angle of 20° with the horizontal plane, and the front and rear ends of the outer surface of the pillar 13 are provided with a limiting mechanism;

[0029] The limiting mechanism includes a connecting ring 19 fixedly installed at one end of the sorting barrel 14 and a fixing ring 27 fixedly installed at both ends of the pillar 13. A slot 23 is provided on one end of the connecting ring 19 close to the workbench 1. A fixing block 22 located at the inner ring of the connecting ring 19 is fixedly installed on the outer surface of the pillar 13. A fixing block 20 is provided on the inner ring surface of the connecting ring 19. A spring 21 is elastically connected between the fixing block 20 and the fixing block 22. A snap ring 24 is slidably installed on the outer surface of the slot 23. A clamping column 25 is fixedly connected to one end of the snap ring 24 facing the connecting ring 19. The clamping column 25 is adapted to be clamped in the slot 23. A permanent magnet 26 is installed on the other end of the snap ring 24. An electromagnet 28 is fixedly installed on one end of the fixing ring 27 facing the permanent magnet 26. A spring 29 located between the snap ring 24 and the fixing ring 27 is movably sleeved on the outer surface of the pillar 13. The two ends of the spring 29 are elastically connected to the fixing ring 27 and the snap ring 24 respectively.

[0030] A discharge plate 16 is fixedly installed on the right side of the inner wall of the sorting platform 12, and a discharge plate 2 17 and a discharge plate 3 18 are fixedly installed on the left side of the inner wall of the sorting platform 12.

[0031] The device has been redesigned to achieve efficient express cargo sorting function, by providing a pillar 13 and rotatably installing two groups of sorting cylinders 14 on the outer surface thereof, receiving express cargo through a sorting slot 15 opened inside the sorting cylinder 14 and preparing for sorting, by providing a connecting ring 19 and a fixed block 1 20 fixedly installed on one end of the sorting cylinder 14, and a fixed block 2 22 fixed on the outer surface of the pillar 13, two groups of springs 1 21 are inserted between the fixed block 1 20 and the fixed block 2 22, when the sorting cylinder 14 rotates, one group of springs 1 21 is compressed, and one group of fixed blocks 2 22 is stretched, Two sets of rebound forces are generated, and the express goods fall on the surface of the sorting slot 15, and their weight is used to drive the sorting cylinder 14 to rotate as a whole. The larger the rotation angle of the sorting cylinder 14, the greater the pressure on the spring 21, that is, the heavier the goods are, and the rotation displacement of the sorting cylinder 14 generated when the spring 21 is compressed is used to guide the express goods from light to heavy to the discharge plate 1 16, the discharge plate 2 17 and the discharge plate 3 18 at one time. This design not only reduces the force on the spring 21 and extends its service life, but also avoids the weight of the workbench 1 from acting entirely on the spring 21, so that the sorting efficiency of the device is higher.

[0032] At the same time, the device is also provided with a snap ring 24 which is slidably installed on the outer surface of the pillar 13, and is fixed to the outermost side of the outer surface of the pillar 13 by a fixing ring 27. The fixing ring 27 is used to compress the snap ring 24, and the snap ring 24 drives the clamping column 25 to clamp into the inside of the clamping slot 23. When heavy goods fall on the sorting slot 15, the grating 11 senses the goods and sends a signal to the controller, so that the controller controls the electromagnet 28 to be energized 1 to 3 seconds after the goods leave the conveyor belt 4, and then quickly cuts off the power. The purpose of this design is that the heavy goods will drive the sorting cylinder 14 to rotate quickly, and when the goods move to the discharge plate 17 or the discharge plate 17, the sorting cylinder 14 will rotate quickly. When the discharge plate 3 18 is aligned, rotation over-position phenomenon will occur, that is, the sorting slot 15 is not coplanar with the discharge plate 2 17 and the discharge plate 3 18, which affects the discharge of the goods from the sorting slot 15. The sorting cylinder 14 rotates rapidly and drives the sorting slot 15 to rotate to a horizontal state. At this time, the clamping column 25 just abuts against the top of the inner wall of the clamping slot 23, thereby eliminating the inertia force generated by the heavier goods. Subsequently, the electromagnet 28 can be energized and absorbs the permanent magnet 26, the clamping ring 24 and the clamping column 25, so that the connecting ring 19 loses the limit of the clamping column 25 and moves downward freely. This design not only ensures the stability of sorting and discharging, but also protects the spring 1 21 from being over-pressurized.

[0033] Note: The 1 to 3 seconds set in this application is based on the movement status of the goods and can also be freely adjusted according to actual use.

[0034] Among them, a bracket 5 is fixedly installed on the right side of the top of the workbench 1, a fixed column 6 is fixedly connected to the bottom of the bracket 5, a sleeve 7 is rotatably installed on the outer surface of the fixed column 6, and a limit plate 1 8, a limit plate 2 9 and a limit plate 3 10 are fixedly installed on the outer surface of the sleeve 7 respectively, and the limit plate 1 8, the limit plate 2 9 and the limit plate 3 10 are equidistantly distributed on the outer surface of the sleeve 7 in a circle, and the limit plate 1 8 is located on the left side of the outer surface of the sleeve 7. A grating 11 is installed on the right side of the workbench 1;

[0035] The device is also designed with two groups of sorting barrels 14, which cooperate with the fixed column 6, the sleeve 7, the limit plate 1 8, the limit plate 2 9 and the limit plate 3 10, so that the two groups of sorting barrels 14 can work alternately to complete the express sorting. By arranging the limit plate 1 8, the limit plate 2 9 and the limit plate 3 10, which are equidistantly distributed on the outer surface of the sleeve 7 and are integrated with the sleeve 7, when the express goods pass through the limit plate 1 8, it will push the limit plate 2 9 or the limit plate 3 10 to rotate. At this time, the limit plate 1 8 will be driven by the sleeve 7 to the side close to the express goods, forming an inclined limit. When the next express goods arrive, the inclined limit plate 1 8 will move the express goods to the other side of the previous express goods, and this cycle is repeated, giving the two groups of sorting barrels 14 time to return to their original positions each time, greatly improving the working efficiency of the device.

[0036] The motor 2 is fixedly mounted on the left side of the front of the workbench 1, the transport rollers 3 are arranged in multiple groups and are rotatably mounted on the inner wall of the workbench 1 and driven by the motor 2, the conveyor belt 4 is movably sleeved on the outer surface of the transport rollers 3, and the grating 11 and the electromagnet 28 are electrically connected to the control;

[0037] The grating 11 and the electromagnet 28 are electrically connected to the controller, and the power on and off and the sensing of the passage of goods are all electrically controlled. This technology is existing technology, so it is not necessary to elaborate on it in this case.

[0038] The clamping ring 24 can drive the clamping column 25 to rotate upward by 20° around the axis of the pillar 13, and can make the outer surface of the clamping column 25 abut against the top of the inner wall of the clamping groove 23;

[0039] like Figure 3 As shown, the clamping column 25 is inserted into the clamping slot 23, so that the overall rotation of the sorting barrel 14 is maintained at the original position. After the sorting barrel 14 rotates downward 20° around the axis of the support 13, the clamping column 25 will abut against the top of the inner wall of the clamping slot 23, thereby limiting the further rotation of the sorting barrel 14. At this time, the sorting slot 15 is in a horizontal state, and the clamping column 25 clamps the sorting barrel 14 to limit its further rotation, thereby offsetting the huge inertial force exerted by the heavy object on the sorting barrel 14.

[0040] Among them, the discharge plate 1 16, the discharge plate 2 17 and the discharge plate 3 18 are all in contact with the outer surface of the sorting cylinder 14, and the plane where the discharge plate 1 16 is located is coplanar with the bottom of the sorting slot 15;

[0041] The discharge plate 1 16, the discharge plate 2 17 and the discharge plate 3 18 are all in contact with the outer surface of the sorting cylinder 14, and they are respectively docked with the sorting cylinder 14 at different rotation angles. The sorting slot 15 is aligned with the discharge plate 16, the discharge plate 2 17 and the discharge plate 3 18 at different angles, and assists in the discharge of goods.

[0042] Among them, the fixed block 1 20 and the fixed block 22 are centrally symmetrically distributed, and the spring 1 21 is provided in two groups, and is respectively located at the two ends of the fixed block 1 20 and the fixed block 22. When the connecting ring 19 rotates, a group of springs 1 21 located on the inner ring surface of the connecting ring 19 is compressed, and the other group of springs 1 21 is stretched;

[0043] When the sorting cylinder 14 drives the connecting ring 19 and the fixing block 1 20 to rotate, the fixing block 2 22 is fixed on the outer surface of the pillar 13 and does not move. At this time, the spring 1 21 will be compressed and stretched to generate a rebound force and limit the sorting cylinder 14 from continuing to rotate. As the pressure on the spring 1 21 is different, its rotation stroke is also different, so that the sorting cylinder 14 can cooperate with the sorting slot 15 to align with the discharge plate 1 16, the discharge plate 2 17 or the discharge plate 3 18 according to different cargo weights to complete the discharge.

[0044] The horizontal distance between the rightmost side of the outer surface of the conveyor belt 4 and the support 13 is smaller than the outer diameter of the sorting cylinder 14, and the opposite surfaces of the two groups of sorting cylinders 14 abut against each other;

[0045] The design of the distance value between the outer surface of the conveyor belt 4 and the sorting cylinder 14 ensures that the express goods can smoothly fall on the sorting slot 15 and complete the subsequent sorting work. The two groups of symmetrically distributed sorting cylinders 14 do not interfere with each other.

[0046] The distance between the end of the electromagnet 28 facing the permanent magnet 26 and the permanent magnet 26 is greater than the distance the snap ring 24 moves along the axis of the pillar 13 toward the end of the fixed ring 27. The outer surface of the pillar 13 is provided with a snap groove, and the inner ring surface of the snap ring 24 is provided with a convex block, which is adapted to be snapped into the snap groove.

[0047] When the electromagnet 28 is energized, it will absorb the permanent magnet 26, causing it to drive the retaining ring 24 and the retaining column 25 to move toward the side away from the slot 23. At this time, the spring 29 is compressed and generates a rebound force for the retaining ring 24 to reset. In order for the retaining column 25 to completely detach from the slot 23, it must have a displacement greater than the depth of the slot 23.

[0048] Working principle:

[0049] First, start the motor 2, and drive the transport roller 3 and the conveyor belt 4 to rotate, drive the express goods on the surface of the conveyor belt 4 along the transport direction, and gradually approach the limit plate 8. When the express goods touch the limit plate 8, the conveyor belt 4 drives the limit plate 8 and the sleeve 7 to rotate to one side around the axis of the fixed column 6 (the front side is taken as an example here). At this time, the left side of the limit plate 8 is close to the front side of the inner wall of the workbench 1, and guides the express goods to the rear side. Then, when the express goods leave the surface of the conveyor belt 4, it will drive the limit plate 3 10 to rotate forward, so that the limit plate 8 is rotated backward by the sleeve 7 and the limit plate 3 10;

[0050] Set the weight of the cargo to three levels: lightest, heavier and heaviest;

[0051] Then, when the express goods pass through the grating 11, the grating 11 sends a signal to the controller and sets a program to energize the electromagnet 28 within 1 to 3 seconds and then quickly cut off the power (the program setting here is the prior art and will not be repeated). When the express goods fall on the surface of the sorting slot 15, the sorting cylinder 14 will be pressed by its own weight, so that the sorting cylinder 14 drives the connecting ring 19 and the fixing block 20 to rotate toward the side close to the card column 25, and compresses a group of springs 21 and stretches another group of springs 21 to generate a rebound support force, such as Figure 5 As shown in the figure, when the express cargo is the lightest, the angle at which the sorting barrel 14 rotates is extremely small. At this time, it can move downward along the 20° slope on the surface of the sorting slot 15 and discharge the cargo through the discharge plate 16. When the weight of the express cargo reaches a heavier weight, the sorting barrel 14 will rotate and move the card slot 23 to the position where the top of its inner wall abuts against the card column 25. At this time, the electromagnet 28 is energized and generates a magnetic attraction to the permanent magnet 26, driving the clamping ring 24 and the card column 25 as a whole to the side close to the fixed ring 27, so that the card column 25 is separated from the inside of the card slot 23, and the card column 25 loses its limit position, and the sorting The barrel 14 will continue to rotate, so that the bottom of the sorting slot 15 is coplanar with the plane where the discharge plate 17 is located. At this time, the sorting barrel 14 stops rotating, and the express goods can be discharged along the discharge plate 17. After the clamping column 25 is separated from the inside of the clamping slot 23, the permanent magnet 26 will quickly cut off the power, and under the action of the spring 29, the clamping ring 24 and the clamping column 25 are pressed, so that the clamping column 25 is in contact with the connecting ring 19. When the express goods are the heaviest, the sorting barrel 14 will be driven by the express goods to continue to rotate, so that the bottom of the sorting slot 15 is coplanar with the discharge plate 18. At this time, the express can be discharged along the discharge plate 18.

[0052] Finally, after the goods are discharged, the sorting cylinder 14 will be reset under the action of the spring 21, so that the clamping column 25 is re-inserted into the clamping slot 23. When the next express cargo passes through the limit plate 8, the limit plate 8 rotating backwards will just guide the express cargo to the front side, and the sorting cylinder 14 on the front side will be responsible for sorting.
