Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and particularly to a sorting device for logistics distribution and a sorting method thereof. Background Art

[0002] The sorting device in logistics distribution is a device used to classify, sort and distribute goods, and is widely used in logistics centers, warehousing and distribution fields to improve the distribution efficiency and accuracy;

[0003] For example, a sorting device for logistics distribution and a sorting method thereof as described in "CN110860478B". The sorting device includes a chassis. A first support frame is installed on the upper surface of the chassis. A first connecting rod is fixed at the top of the first support frame. A second connecting rod is fixedly installed at the far end of the first connecting rod. Installation plates are fixed at both ends of the second connecting rod. A second motor is installed on the top of the installation plate. A rotating push plate is installed at the output shaft end of the second motor. A second support frame is also installed on the upper surface of the chassis. A turntable shaft is provided at the top of the second support frame. A turntable is horizontally fixed at the top of the turntable shaft. Second belt conveyors are provided on both sides of the turntable. The second belt conveyors are installed on the outer wall of the housing. A lifting assembly is movably provided inside the housing; the structure of the present invention is simple, the production cost is low, the whole process adopts automatic operation, which is convenient for people to use, the overall structure is compactly installed, occupies little space, and is convenient for handling the sorted items;

[0004] However, in the prior art, after the sorting device for sorting express deliveries usually finishes sorting the express deliveries, they slide out from the corresponding sorting channels. In order to facilitate the collection of express deliveries, a storage box is usually placed at the lower end of the sorting channel. The express deliveries fall into the storage box in a mess. When collecting the express deliveries, the staff needs to take out the express deliveries in the storage box one by one and stack them on one side, and transfer them through a special forklift for express deliveries or other transfer equipment. This process requires a large number of taking operations by the staff, with a high labor intensity. And if the sorting speed is relatively fast, the storage box needs to be frequently replaced to carry the express deliveries, and the operation is rather inconvenient. Summary of the Invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that there is a lack of an automatic stacking function for the sorted express deliveries, so manual stacking and collection are required, resulting in a large working intensity for the staff.

[0007] To solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a sorting device for logistics distribution, which includes a sorting chute arranged on the side of the sorting conveyor belt body. A platform is provided at the lower end of the sorting chute, and a stacking mechanism is detachably arranged on the platform. The stacking mechanism includes a housing, a stacking rack and a lifting mechanism. A partition rack is arranged at the central position inside the housing. The inside of the housing is divided into two stacking spaces by the partition rack. A transition table is arranged at the central position of the sorting chute, and a first spherical wheel conveyor body is arranged on the transition table. A laser profile scanner is arranged on the housing directly above the first spherical wheel conveyor body. The feeding end of the housing is communicated with a feeding rack, and a second spherical wheel conveyor body is arranged on the inner wall of the feeding rack. The second spherical wheel conveyor body is slidably arranged above the platform. A feeding rack is arranged above the housing, and the stacking rack is located inside the feeding rack. A bracket is arranged below the stacking space through the lifting mechanism, and the lower end of the stacking rack is slidably arranged above the bracket. A pushing mechanism is arranged in the feeding rack below the platform, and a discharge port is arranged on the side wall of the housing directly opposite to the pushing mechanism. The stacking rack includes a bottom plate, partition plates and hinge members. A plurality of partition plates are arranged and stacked above the bottom plate. The bottom plate and the partition plates and adjacent partition plates are respectively assembled and connected through hinge members. A plurality of hinge members are arranged and are respectively located at the four sides of the partition plates. A guiding conveyor belt for limiting the two sides of the stacking rack is arranged inside the feeding rack. Vibration mechanisms are arranged on the inner wall of the housing and the side wall of the partition rack below the platform, and the vibrating ends of the vibration mechanisms extend between the bottom plate and the partition plates and between adjacent partition plates.

[0009] Further, the hinge member includes a first hinge strip and a second hinge strip. A plurality of first hinge strips are arranged and are respectively located at the other three sides of the partition plate away from the platform. Two second hinge strips are arranged and symmetrically slidably arranged at the two corners of the partition plate close to the platform. The hinge structures of the first hinge strip and the second hinge strip are the same. A group of the first hinge strips is provided with two hinge plates, and the end faces of the hinge plates are respectively hinged to another hinge plate and the partition plate. By arranging the first hinge strip and the second hinge strip, the first hinge strip is used to limit the goods during the placement process, and the second hinge strip is used to limit the goods after the placement is completed, so as to prevent the goods from tipping over.

[0010] Further, the two hinge plates on the second hinge bar are respectively rotatably connected by two half plates. A sliding block is provided at one end of each half plate. A right-angle groove for slidably arranging the sliding block is provided at the corner of the partition plate. A main gear is rotatably provided on the end face of the sliding block. A rack meshing with the main gear is provided on one side of the inner wall of the right-angle groove. The main gear is driven to rotate by a motor. The motor is only slidably arranged in the right-angle groove. A photoelectric sensor is provided on the inner wall of the housing below the vibration mechanism. The output end of the photoelectric sensor faces the second hinge bar. During the process of placing the goods, the second hinge bar is on the same plane as the first hinge bar. After the placement is completed, the second hinge bar moves to the side of the partition plate facing the platform to realize the limitation of the goods. A control box is provided on the housing. A single-chip microcomputer is built in the control box. The photoelectric sensor is electrically connected to the motor through the single-chip microcomputer. When the second hinge bar passes by the photoelectric sensor, the photoelectric sensor emits a beam of light onto the second hinge bar and receives the light reflected back by the second hinge bar. By detecting the occlusion, reflection or transmission of the light, it is judged whether it is the second hinge bar. When it is determined to be the second hinge bar, a signal is transmitted to the single-chip microcomputer, which is converted into an electrical signal and transmitted to the motor to control the rotation of the motor and drive the second hinge bar to move in the right-angle groove.

[0011] Further, the vibration mechanism includes a fixed frame, a telescopic shaft and a vibration plate. The fixed frame is embedded in the inner wall of the housing and the partition frame below the platform. A plurality of ultrasonic transducers are provided inside the fixed frame. The ultrasonic transducers are provided with a vibration plate through the telescopic shaft. A first magnetic sheet is provided on the fixed frame. A second magnetic sheet is provided on the back of the vibration plate and is arranged to adsorb to the first magnetic sheet. The first magnetic sheet is electrically connected to an external power supply. An ultrasonic generator is provided on the housing. Through the cooperation of the ultrasonic generator and the ultrasonic transducers, the ultrasonic generator transmits high-frequency electrical signals to the ultrasonic transducers through a cable. After receiving the signals, the transducers convert the electrical energy into high-frequency mechanical vibrations by using the piezoelectric effect, and cooperate with the telescopic shaft to drive the vibration plate to vibrate, so as to realize the position adjustment of the goods. When the vibration mechanism is not in use, such as during the up and down movement of the bracket, the first magnetic sheet can be electrified so that the second magnetic sheet adsorbs to the first magnetic sheet to avoid obstacles caused by the up and down movement of the bracket.

[0012] Further, the guiding conveyor belt is located between the loading rack and the stacking space above. The outer wall of the guiding conveyor belt is provided with a main support plate and an auxiliary support plate. The main support plate is used to support both sides of the bottom plate, and the auxiliary support plate is used to support both sides of the partition plate. The two guiding conveyor belts are arranged to rotate synchronously and in opposite directions. The guiding conveyor belt is driven to rotate by a motor. By driving the two guiding conveyor belts to rotate synchronously and in opposite directions through the motor drive, the bottom plate or the partition plate can be smoothly moved down. One end of the built-in rotating shaft of one of the guiding conveyor belts is meshed with a gear, and this gear is linked with one end of the built-in rotating shaft of the other guiding conveyor belt through a belt, so that the two guiding conveyor belts can rotate synchronously and in opposite directions.

[0013] Furthermore, the pushing mechanism includes a first cylinder and a push plate. One end of the first cylinder is located in the feeding rack below the platform, and the output end of the first cylinder is assembled and connected to the push plate. The lifting mechanism is a second cylinder, and the bracket moves up and down through the second cylinder. A clamping groove is provided on the bracket, and a clamping strip slidably arranged with the clamping groove is provided below the bottom plate. When discharging, the first cylinder is driven to drive the push plate to move, and the bottom plate on the bracket is pushed out of the discharge port.

[0014] Furthermore, a disassembly mechanism is provided inside the platform. The disassembly mechanism includes a push block, an insertion shaft, and a push shaft. The push shaft is slidably arranged at the central position of the platform. The push block is arranged at one end of the push shaft away from the sorting slideway. Two hinge shafts are symmetrically hinged on both sides of the other end of the push shaft. The end face of the hinge shaft is hinged to one end of the insertion shaft. The insertion shaft is symmetrically slidably arranged on both sides of the platform. The end face of the insertion shaft is slidably engaged with the inner wall of the housing. When installing the stacking mechanism, the housing is slid in the direction of the platform, so that the platform slides into the housing until the platform is completely immersed in the housing. During this process, the inner wall of the housing presses the push block, driving the push shaft to slide into the platform. Since the push shaft is perpendicular to the insertion shaft and the length of the hinge shaft remains unchanged, the two insertion shafts move synchronously and in opposite directions, and the end face of the insertion shaft extends out of both sides of the platform and is engaged with the inner wall of the housing to achieve limiting.

[0015] Furthermore, a bevel shaft is rotatably arranged on the end face of the insertion shaft. An inclined groove and a central groove are provided on the side wall of the bevel shaft. One end of the central groove facing the hinge shaft is communicated with the inclined groove. The inclined groove occupies half of the cross-section of the bevel shaft. A slot for passing through the bevel shaft is provided on the platform. A slider slidably arranged with the inclined groove and the central groove is provided on the inner wall of the slot. The bevel of the bevel shaft in the slot state faces the sorting slideway, and the slider is located in the central groove. When the bevel shaft moves outwards, the slider slides on the central groove, and the bevel direction of the bevel shaft remains unchanged. When the bevel shaft is engaged with the housing, the slider slides with the inclined groove, and the sliding process drives the bevel shaft to rotate 180 degrees, realizing the flipping of the bevel. At this time, when the housing is pulled outwards, it cannot slide out. On the contrary, when separating, the slider first passes through the inclined groove to drive the bevel shaft to rotate 180 degrees in the reverse direction, driving the bevel of the bevel shaft to face the sorting slideway direction, thereby facilitating the separation of the bevel shaft from the housing.

[0016] Furthermore, a limiting groove engaged with the bevel shaft is provided on the inner wall of the feeding rack, and an end groove adapted to the push block is provided on the inner wall of the feeding rack. A magnet is provided in the end groove, and a strong magnet block adsorbed to the magnet is provided on the end face of the push block. The magnet is electrically connected to an external power supply. By energizing the magnet, the strong magnet block and the push block move into the end groove, driving the hinge shaft to pull the two insertion shafts to move synchronously and towards each other, driving the bevel shaft to contract into the inclined groove.

[0017] On the other hand, the present invention provides a sorting method for a sorting device used in logistics distribution, including,

[0018] Step S1: The sorted express deliveries are transferred from the sorting conveyor belt body to the sorting chute. By driving the first spherical wheel conveyor body, the goods stay briefly on the first spherical wheel conveyor body. The appearance of the goods is quickly scanned by a laser profile scanner to remove irregular goods, and the regular goods are left and conveyed onto the second spherical wheel conveyor body;

[0019] Step S2: The bracket is lifted to the platform by the lifting mechanism, and the two guiding conveyor belts are driven to rotate, driving the stacking rack at the bottom to move downward. The bottom plate at the lower end of the stacking rack is separated from the guiding conveyor belt and smoothly lands on the bracket. Through the coordinated adjustment of the bracket and the guiding conveyor belt, the upper part of the bottom plate is flush with the platform;

[0020] Step S3: The goods sliding onto the second spherical wheel conveyor body can be uniformly conveyed by the second spherical wheel conveyor body onto the bottom plate in a stacking space, and the second spherical wheel conveyor body arranges the goods in sequence;

[0021] Step S4: After one layer is placed, the lifting mechanism is driven to drive the bracket to move downward, and at the same time, the guiding conveyor belt rotates, releasing the partition at the lowermost end. Under the action of gravity, the hinge automatically unfolds, so that the partition is just located at the platform position. The space opened by the hinge between the two partitions is used to place a new round of goods;

[0022] Step S5: When the placed and moved-down goods pass through the vibration mechanism, the vibration mechanism is driven to push the goods towards the center, making the goods neatly arranged;

[0023] Step S6: When the second hinge bar passes through the photoelectric sensor, the motor on the sliding block is driven to drive the main gear to rotate, and then drive the second hinge bar to move in the right-angle groove, moving the second hinge bar to the side close to the platform;

[0024] Step S7: After a stacking rack is stacked, when stacking again, the stacking rack in another stacking space is used. At this time, the stacked stacking rack can be pushed out from the discharge port through the pushing mechanism.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. After sorting, the present invention stacks and places the goods through the stacking mechanism, saving the labor of workers manually taking and palletizing.

[0027] 2. The stacking rack provided by the present invention is used to stack goods layer by layer on the stacking rack, with one layer of goods placed on each partition board. By cooperating with the hinge parts arranged on each side of the partition board, the situation of goods collapsing during manual handling can be effectively reduced.

[0028] 3. Through the cooperation of the ultrasonic generator and the ultrasonic transducer, the ultrasonic generator transmits high-frequency electrical signals to the ultrasonic transducer through a cable. After receiving the signal, the transducer converts electrical energy into high-frequency mechanical vibration by using the piezoelectric effect, and cooperates with the telescopic shaft to drive the vibrating plate to vibrate, so as to realize the position adjustment of the goods.

[0029] 4. The two groups of guiding conveyor belts provided by the present invention are used for smoothly loading the stacking rack, and cooperate with the bracket to facilitate the stacking operation after each partition board is opened. BRIEF DESCRIPTION OF THE DRAWINGS

An outlet 7 is provided on the side wall of the housing 411 directly opposite to the pushing mechanism. The stacking rack 412 includes a bottom plate 811, partition plates 812, and hinge members. A plurality of partition plates 812 are provided and stacked above the bottom plate 811. The bottom plate 811 and the partition plates 812 and between adjacent partition plates 812 are respectively assembled and connected through hinge members. A plurality of hinge members are provided and are respectively located at the four sides of the partition plates 812. A guiding conveyor belt 9 for limiting both sides of the stacking rack 412 is provided inside the loading rack 5. A vibration mechanism is provided on the inner wall of the housing 411 and the side wall of the partition frame 413 below the platform 3. The vibrating end of the vibration mechanism extends between the bottom plate 811 and the partition plates 812 and between adjacent partition plates 812.

[0049] As Figures 1 - 12As shown in the figure, the hinge member includes a first hinge strip 101 and a second hinge strip 102. A plurality of first hinge strips 101 are provided and are respectively located at the other three sides of the partition 812 away from the platform 3. Two second hinge strips 102 are provided and are symmetrically and slidably arranged at two corners of the partition 812 close to the platform 3. The hinge structures of the first hinge strip 101 and the second hinge strip 102 are the same. Two hinge plates 103 are provided in a group of first hinge strips 101. The end faces of the hinge plates 103 are respectively hinged to another hinge plate 103 and the partition 812. By providing the first hinge strip 101 and the second hinge strip 102, the first hinge strip 101 is used to limit the goods during the placement process, and the second hinge strip 102 is used to limit the goods after the placement is completed, so as to prevent the goods from tipping over.

[0050] As Figures 1 - 12 As shown in the figure, the two hinge plates 103 on the second hinge strip 102 are respectively rotationally connected by two half plates. A sliding block 111 is provided at one end of each half plate. A right-angle groove 112 for slidably arranging the sliding block 111 is provided at the corner of the partition 812. A main gear 113 is rotatably provided at the end face of the sliding block 111. A rack 114 meshing with the main gear 113 is provided on one side of the inner wall of the right-angle groove 112. The main gear 113 is driven to rotate by a motor 115. The motor 115 is only slidably arranged in the right-angle groove 112. A photoelectric sensor 116 is provided on the inner wall of the housing 411 below the vibration mechanism. The output end of the photoelectric sensor 116 faces the second hinge strip 102. During the placement process of the goods, the second hinge strip 102 is located on the same side as the first hinge strip 101. After the placement is completed, the second hinge strip 102 moves to the side of the partition 812 facing the platform 3 to realize the limitation of the goods. A control box is provided on the housing 411. A single-chip microcomputer is built in the control box. The photoelectric sensor 116 is electrically connected to the motor 115 through the single-chip microcomputer. When the second hinge strip 102 passes by the photoelectric sensor 116, the photoelectric sensor 116 emits a beam of light onto the second hinge strip 102 and receives the light reflected back by the second hinge strip 102. Whether it is the second hinge strip 102 is judged by detecting the occlusion, reflection or transmission of the light. When it is determined to be the second hinge strip 102, a signal is transmitted to the single-chip microcomputer, which is converted into an electrical signal and transmitted to the motor 115 to control the rotation of the motor 115 and drive the second hinge strip 102 to move in the right-angle groove 112.

[0051] As Figures 1 - 12As shown in the figure, the vibration mechanism includes a fixed frame 121, a telescopic shaft 122, and a vibration plate 123. The fixed frame 121 is embedded in the inner wall of the housing 411 and the partition frame 413 below the platform 3. A plurality of ultrasonic transducers 124 are provided inside the fixed frame 121. The ultrasonic transducers 124 are provided with a vibration plate 123 through the telescopic shaft 122. A first magnetic sheet 125 is provided on the fixed frame 121, and a second magnetic sheet 126 that is adsorbed to the first magnetic sheet 125 is provided on the back of the vibration plate 123. The first magnetic sheet 125 is electrically connected to an external power source. An ultrasonic generator 127 is provided on the housing 411. Through the cooperation of the ultrasonic generator 127 and the ultrasonic transducers 124, the ultrasonic generator 127 transmits high-frequency electrical signals to the ultrasonic transducers 124 through a cable. After receiving the signals, the transducers convert electrical energy into high-frequency mechanical vibrations using the piezoelectric effect, and cooperate with the telescopic shaft 122 to drive the vibration plate 123 to vibrate, realizing the position adjustment of the goods. When the vibration mechanism is not in use, such as during the up and down movement of the bracket 6, the first magnetic sheet 125 can be energized to make the second magnetic sheet 126 adsorbed to the first magnetic sheet 125, avoiding obstacles during the up and down movement of the bracket 6.

[0052] As Figures 1 - 12 As shown in the figure, the guiding conveyor belt 9 is located between the loading rack 5 and the stacking space above. The outer wall of the guiding conveyor belt 9 is provided with a main support plate 131 and an auxiliary support plate 132. The main support plate 131 is used to support both sides of the bottom plate 811, and the auxiliary support plate 132 is used to support both sides of the partition plate 812. The two guiding conveyor belts 9 are arranged to rotate synchronously and in opposite directions. The guiding conveyor belt 9 is driven to rotate by a motor 133. By driving the motor 133 to drive the two guiding conveyor belts 9 to rotate synchronously and in opposite directions, the bottom plate 811 or the partition plate 812 can be smoothly moved down. One end of the built-in rotating shaft of one of the guiding conveyor belts 9 is engaged with a gear, and this gear is linked to one end of the built-in rotating shaft of the other guiding conveyor belt 9 through a belt, enabling the two guiding conveyor belts 9 to rotate synchronously and in opposite directions.

[0053] As Figures 1 - 12 As shown in the figure, the pushing mechanism includes a first cylinder 141 and a pushing plate 142. One end of the first cylinder 141 is located inside the feeding rack 417 below the platform 3, and the output end of the first cylinder 141 is assembled and connected to the pushing plate 142. The lifting mechanism is a second cylinder 15, and the bracket 6 moves up and down through the second cylinder 15. A clamping groove 161 is provided on the bracket 6, and a clamping bar 162 that is slidably arranged with the clamping groove 161 is provided below the bottom plate 811. During unloading, by driving the first cylinder 141 to drive the pushing plate 142 to move, the bottom plate 811 on the bracket 6 can be pushed out of the discharge port 7.

[0054] As Figures 1 - 12As shown, a disassembly mechanism is provided inside the platform 3. The disassembly mechanism includes a push block 171, an insertion shaft 172, and a push shaft 173. The push shaft 173 is slidably arranged at the central position of the platform 3. The push block 171 is arranged at one end of the push shaft 173 away from the sorting chute 2. Two hinge shafts 174 are symmetrically and hingedly arranged on both sides of the other end of the push shaft 173. One end of the hinge shaft 174 is hingedly arranged with one end of the insertion shaft 172. The insertion shafts 172 are symmetrically and slidably arranged on both sides of the platform 3. The end face of the insertion shaft 172 is slidably engaged with the inner wall of the housing 411. When installing the stacking mechanism, by sliding the housing 411 in the direction of the platform 3, the platform 3 slides into the housing 411 until the platform 3 is completely immersed in the housing 411. During this process, the inner wall of the housing 411 presses the push block 171, driving the push shaft 173 to slide into the platform 3. Since the push shaft 173 is perpendicular to the insertion shaft 172 and the length of the hinge shaft 174 remains unchanged, the two insertion shafts 172 move synchronously and in opposite directions, and the end face of the insertion shaft 172 extends out of both sides of the platform 3 and is engaged with the inner wall of the housing 411 to achieve limiting.

[0055] As Figures 1 - 12 As shown, a bevel shaft 181 is rotatably arranged at the end face of the insertion shaft 172. An inclined groove 182 and a central groove 183 are arranged on the side wall of the bevel shaft 181. One end of the central groove 183 facing the hinge shaft 174 is communicated with the inclined groove 182. The inclined groove 182 occupies half of the cross-section of the bevel shaft 181. A slot 184 for passing through the bevel shaft 181 is arranged on the platform 3. A slider 185 slidably arranged with the inclined groove 182 and the central groove 183 is arranged on the inner wall of the slot 184. The bevel of the bevel shaft 181 in the state inside the slot 184 faces the sorting chute 2, and the slider 185 is located in the central groove 183. When the bevel shaft 181 moves outwards, the slider 185 slides on the central groove 183, and the bevel direction of the bevel shaft 181 remains unchanged. When the bevel shaft 181 is engaged with the housing 411, the slider 185 slides with the inclined groove 182, and the sliding process drives the bevel shaft 181 to rotate 180 degrees, realizing the flipping of the bevel. At this time, when the housing 411 is pulled outwards, it cannot slide out. On the contrary, when separating, the slider 185 first passes through the inclined groove 182 to drive the bevel shaft 181 to rotate 180 degrees in the reverse direction, driving the bevel of the bevel shaft 181 to face the sorting chute 2 direction, thereby facilitating the separation of the bevel shaft 181 from the housing 411.

[0056] As Figures 1 - 12As shown in the figure, a limiting groove 191 engaged with the inclined plane shaft 181 is provided on the inner wall of the feeding rack 417, an end groove 192 adapted to the pushing block 171 is provided on the inner wall of the feeding rack 417, a magnet 193 is provided in the end groove 192, a strong magnet block is provided on the end face of the pushing block 171 and is adsorbed to the magnet 193. The magnet 193 is electrically connected to an external power supply. By energizing the magnet 193, the strong magnet block and the pushing block 171 move into the end groove 192, driving the articulated shaft 174 to pull the two inserting shafts 172 to move synchronously towards each other, and driving the inclined plane shaft 181 to contract into the inclined groove 182.

[0057] Working principle:

[0058] Step S1: The sorted express parcels are transferred from the sorting conveyor belt body 1 to the sorting chute 2. By driving the first spherical wheel conveyor body 415, the goods stay briefly on the first spherical wheel conveyor body 415. The appearance of the goods is quickly scanned by the laser profile scanner 416 to remove irregular goods, and the regular goods are left and conveyed to the second spherical wheel conveyor body 418.

[0059] Step S2: The lifting mechanism is used to lift the bracket 6 to the platform 3, and the two guiding conveyor belts 9 are driven to rotate, driving the stacking rack 412 at the bottom to move downwards. The bottom plate 811 at the lower end of the stacking rack 412 is separated from the guiding conveyor belt 9 and stably lands on the bracket 6. By adjusting the cooperation between the bracket 6 and the guiding conveyor belt 9, the upper part of the bottom plate 811 is flush with the platform 3.

[0060] Step S3: The goods sliding onto the second spherical wheel conveyor body 418 can be uniformly conveyed by the second spherical wheel conveyor body 418 to the bottom plate 811 in a stacking space, and the second spherical wheel conveyor body 418 places the goods in sequence.

[0061] Step S4: After one layer is placed, the lifting mechanism is driven to drive the bracket 6 to move downwards, and at the same time, the guiding conveyor belt 9 rotates to release the lowermost partition plate 812. Under the action of gravity, the articulated part automatically unfolds, so that the partition plate 812 is just located at the position of the platform 3. The space between the two partition plates 812 opened by the articulated part is used to place a new round of goods.

[0062] Step S5: When the goods placed and moved down pass through the vibration mechanism, the vibration mechanism is driven to push the goods towards the center, making the goods placed neatly.

[0063] Step S6: When the second articulated bar 102 passes through the photoelectric sensor 116, the motor 115 on the sliding block 111 is driven to drive the main gear 113 to rotate, and then drive the second articulated bar 102 to move in the right-angled groove 112, moving the second articulated bar 102 to the side close to the platform 3.

[0064] Step S7: After a pallet rack 412 is palletized, when palletizing again, use the pallet rack 412 in another palletizing space. At this time, the pallet rack 412 that has been palletized can be pushed out from the discharge port 7 through the pushing mechanism.

[0065] After the sorted express parcels are transferred from the sorting conveyor belt body 1 to the sorting chute 2, the goods will first pass through the first spherical wheel conveyor body 415. By driving the first spherical wheel conveyor body 415, the goods will stay briefly on the first spherical wheel conveyor body 415. During the stay, the laser profile scanner 416 quickly scans the appearance of the goods. If the goods are of a normal square shape, automatic stacking can be achieved, and the goods will continue to be conveyed downward along the sorting chute 2 directly through the first spherical wheel conveyor body 415 to the second spherical wheel conveyor body 418. If the goods are of irregular shapes, such as spherical or long strip-shaped and are difficult to stack, the goods will be directly pushed to one side by the first spherical wheel conveyor body 415. A storage box is placed in advance below one side of the sorting chute 2, and the irregular goods will directly fall into the storage box. This process can separate the goods that are convenient for stacking and avoid the situation of the goods collapsing after stacking, resulting in stacking failure. Before the goods are stacked, the bracket 6 is first lifted to the platform 3 by the lifting mechanism, and the two guiding conveyor belts 9 are driven to rotate, driving the stacking rack 412 at the bottom to move downward. The bottom plate 811 at the lower end of the stacking rack 412 is separated from the guiding conveyor belt 9 and smoothly lands on the bracket 6. By adjusting the cooperation between the bracket 6 and the guiding conveyor belt 9, the upper part of the bottom plate 811 is flush with the platform 3. When the goods sliding onto the second spherical wheel conveyor body 418 can be conveyed to the bottom plate 811 in a stacking space uniformly through the second spherical wheel conveyor body 418. The spherical wheel conveyor is commonly used in logistics sorting. It utilizes the multi-directional rotation characteristics of the spherical roller units to achieve multi-directional conveying, shunting, guiding, and positioning of items. Each spherical roller unit consists of a high-hardness sphere, a support seat, and internal ball bearings or bearings, ensuring that the sphere can rotate freely with low friction at 360°. Its power source comes from the driving device below, such as a conveyor belt, a driving friction wheel, or a pneumatic system, which generates friction by contacting the sphere, drives the sphere to rotate, and makes the item move in the set direction. The core advantages of the conveyor are flexibility and efficiency. Multiple spherical roller units can be combined into a modular structure. By independently controlling the movement directions and speeds of different units, the item can be flexibly switched between functions such as linear conveying, left and right shunting, and rotational guiding. By setting the second spherical wheel conveyor body 418, the goods can be successively pushed to different positions on the bottom plate 811, making the goods placed relatively neatly. After one layer is placed, the lifting mechanism is driven to drive the bracket 6 to move downward, and at the same time, the guiding conveyor belt 9 rotates, releasing the lowest partition plate 812. Under the action of gravity, the hinge automatically unfolds, making the partition plate 812 just located at the position of the platform 3. The space opened by the hinge between the two partition plates 812 is used to place a new round of goods. Similarly, the goods are placed through the second spherical wheel conveyor body 418. Since the goods placed through the second spherical wheel conveyor body 418 are not particularly neat, when the placed goods move down to the vibration mechanism position, the vibration mechanism is driven,The goods can be centrally pushed in to achieve the effect of neat edges. After the goods are arranged neatly by vibration, the second hinge strip 102 is moved to the side facing the platform 3, so that hinge pieces are provided on all four sides between adjacent partitions 812, achieving the effect of limiting the goods inside and preventing the goods from falling off during handling. Repeat the above steps until the entire stacking rack 412 is fully stacked with goods. When one stacking rack 412 is stacked, when stacking again, use the stacking rack 412 in another stacking space. At this time, the stacked stacking rack 412 can be pushed out from the discharge port 7 through the pushing mechanism. The pushed-out stacking rack 412 can be manually carried by the staff or transferred by equipment, and the goods are difficult to fall during the transfer process.
