Description

Technical Field

[0001] This invention relates to a layered folding protection structure for intelligent sorting equipment and the intelligent sorting equipment itself. It is a protective structure installed on intelligent sorting equipment and belongs to the field of intelligent logistics technology. In particular, it relates to a layered protection structure that uses multiple sets of folding shelves to store express parcels in layers, which can reduce the damage to express parcels that fall from the bottom layer first. Background Technology

[0002] With societal development, online shopping has become a primary mode of consumption. During the process of transporting parcels from their origin to their destination, they need to be sorted and stacked according to their final destination for rapid transit. Currently, sorting is mainly done manually, but this method is inefficient, labor-intensive, and prone to errors, preventing parcels from reaching their correct destinations. Therefore, intelligent sorting lines have emerged. Existing intelligent sorting systems first use readers on a conveyor belt to automatically read the barcodes of the parcels. Then, the control system receives the data from the readers and sorts the parcels according to pre-set parameters. The rules process the read data and generate sorting instructions. Finally, sorting devices, such as push rods, chutes, or pneumatic devices, sort express parcels to different destinations into corresponding containers according to the sorting instructions issued by the control system. However, when the barcode of the express parcel is not aligned with the reader, the existing intelligent sorting method cannot automatically identify the destination of the express parcel. The control system cannot issue the correct sorting instructions for the express parcel, so the sorting device cannot sort the express parcel into the corresponding container. This causes the express parcel to stay on the conveyor belt for a long time or enter the wrong container, resulting in low sorting efficiency and sorting accuracy.

[0003] CN209792017U discloses a rotary sorting machine, including a bag feeding system, a rotary system disposed at the outlet of the bag feeding system, and several bag dropping frames surrounding the outside of the rotary system. The bag feeding system includes a bag dropping section, an information collection section, a rapid bag dropping section, and servo motors for driving the bag dropping section and the rapid bag dropping section, arranged sequentially along the bag dropping direction. The rotary system includes a main support frame, a rotary support, and a drive motor. An electric roller corresponding to the bag dropping frame is provided on the outside of the rotary support, and a baffle is provided between adjacent electric rollers. A guide groove is provided between the electric roller and the bag dropping frame, and a first inclined plate is provided on one side of the guide groove, the first inclined plate being inclined in a direction opposite to the rotation direction of the rotary support. The aforementioned rotary sorting machine collects information about the goods using a barcode reader and sorts them into different drop racks based on that information. However, when the barcode on a product is not aligned with the barcode reader, the rotary sorting machine cannot automatically recognize the product information and cannot sort it. This results in the product remaining on the rotary support for an extended period or ending up in an incorrect drop rack, leading to low sorting efficiency and accuracy.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "An Intelligent Sorting Device," which uses a sorting mechanism to sort barcode-identifiable express parcels into corresponding classification bins based on their destinations. This intelligent sorting device uses a second conveyor belt to directly place express parcels destined for the same destination into the classification bins. Under gravity, the parcels quickly fall to the bottom of the bins or collide with parcels that have fallen earlier. Parcels that fall earlier are subjected to multiple impacts from subsequently falling parcels, easily leading to damage. Summary of the Invention

[0069] The two ends of the U-shaped support rod are respectively positioned on the sides of the two side baffles. The U-shaped support rod is located above the first conveyor belt and close to the other end of the first conveyor belt. A reader is placed in the center of the inner top surface of the U-shaped support rod.

[0070] Preferably, the intelligent sorting equipment further includes a control system, which comprises a signal converter, a data processor, and a controller.

[0071] The signal converter, the data processor, and the controller are all mounted on the bracket.

[0072] The camera, the reader, and the signal converter are connected via a data cable.

[0073] The first telescopic rod, the second telescopic rod, the third telescopic rod, the fourth telescopic rod, the first rotating motor, the second rotating motor, and the drive motor are connected to the controller via a data transmission line.

[0074] The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the controller via a data transmission line.

[0075] The signal converter can convert the electrical signals of the image data captured by the camera and the barcode data of the express package captured by the reader into digital signals.

[0076] The controller can be implemented by one or more application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components to execute instructions from a data processing device.

[0077] The data processor and the signal converter exchange information.

[0078] When the control system is executed, it mainly performs the following steps:

[0079] Before sorting express parcels, the control system pre-sets the destination of each parcel corresponding to a U-shaped baffle. For example, U-shaped baffle 1 corresponds to Jiangsu Province, U-shaped baffle 2 to Shaanxi Province, U-shaped baffle 3 to Zhejiang Province, and so on. Multiple U-shaped baffles correspond one-to-one with multiple sorting bins. For example, parcels on U-shaped baffle 1 are sorted into sorting bin 1, parcels on U-shaped baffle 2 are sorted into sorting bin 2, parcels on U-shaped baffle 3 are sorted into sorting bin 3, and so on. The system also pre-sets the rotation speeds of the drive motor and the second rotating motor, ensuring that when a parcel reaches one end of the first conveyor belt, the corresponding U-shaped baffle rotates to the position corresponding to that end of the first conveyor belt, allowing the parcel to be transferred from the first conveyor belt to the second conveyor belt of that U-shaped baffle. Multiple U-shaped baffles also correspond one-to-one with multiple cameras. For example, U-shaped baffle 1 corresponds to camera 1, U-shaped baffle 2 corresponds to camera 2, and so on.

[0080] During the sorting of express parcels, the parcels are placed on the first conveyor belt with spacing, and the reader collects the barcode data on the parcels.

[0081] When the barcode reader can collect the barcode data of the express package, it sends the collected barcode data to the signal converter. The signal converter converts the electrical signal of the received barcode data into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received barcode data, identifies the destination of the express package in the barcode data, finds the U-shaped baffle corresponding to the destination, the controller controls the drive motor to rotate, the drive motor controls the drive turntable to rotate, the drive turntable drives the driven turntable to rotate, and the driven turntable drives the collection cylinder, connecting disc and multiple U-shaped baffles to rotate, so that the package is aligned with the destination. A U-shaped baffle corresponding to the parcel rotates and approaches the first conveyor belt, causing the parcel to be transferred from the first conveyor belt to a second conveyor belt on the same baffle. When the U-shaped baffle rotates close to the corresponding sorting bin, the controller activates the first rotating motor corresponding to the baffle. The first rotating motor drives the first meshing gear to rotate, which in turn drives the second meshing gear to rotate. The second meshing gear then drives the second conveyor belt to rotate, transferring the parcel to the corresponding sorting bin. This process repeats continuously, sorting parcels whose barcode destination can be identified by the reader into the corresponding sorting bins.

[0082] When the barcode reader fails to collect the barcode data of the express package, and the control system cannot identify the destination in the barcode data, the controller activates multiple cameras. The express package is conveyed from the first conveyor belt to the second conveyor belt of any U-shaped baffle. The camera captures images of the express package on each U-shaped baffle and sends the captured image data signal to the signal converter. The signal converter converts the received image data signal from an electrical signal into a digital signal and sends it to the data processor. The data processor processes the received digital signal of the image data to identify the barcode in the image data. When the barcode cannot be identified, the controller controls the drive motor to stop rotating, and the controller controls the support crossbar where the camera is located to... The second and third telescopic rods are activated. The second telescopic rod retracts towards the U-shaped baffle, and the third telescopic rod extends downward, causing the first telescopic rod and the first gripper to move directly above the package. The controller then activates the first telescopic rod, which extends downward to grip the package with the two first grippers. The controller then retracts the third telescopic rod upward, and the second telescopic rod retracts towards the collection bin, moving the first telescopic rod and the first gripper above the collection bin. The controller then retracts the first telescopic rod upward, causing the two first grippers to separate and drop the package into the collection bin. This process is repeated to sort packages whose barcode destination cannot be identified by the reader into the collection bin for further re-sorting.

[0083] Furthermore, a flexible sheet is provided on the other side of the first gripper, and anti-slip textures are formed on the flexible sheet. The anti-slip textures include horizontal anti-slip textures and vertical anti-slip textures, which are arranged alternately.

[0084] Furthermore, the second conveyor belt is provided with multiple rubber pads, and each rubber pad corresponds to one of the multiple second conveyor belts. Beneficial effects

[0085] 1. By using the fourth telescopic rod and connecting slot to open and close the same set of folding shelves, it is possible to store express parcels in layers, reducing the damage to express parcels that fall from the bottom layer first;

[0086] It has a simple structure and is convenient and practical.

[0087] Second, it is low in cost and easy to promote. Attached Figure Description

Detailed Implementation Example 1

[0101] The present invention discloses a layered folding protective structure for an intelligent sorting device, comprising a sorting bin (16), a folding shelf (44), a connecting block (45), a connecting groove (46), a fixing connector (47), and a fourth telescopic rod (48).

[0102] The sorting bin (16) has an open top surface.

[0103] An ultrasonic ranging module is placed on the top surface of the sorting bin (16).

[0104] The inner side of the sorting bin (16) has a connecting groove (46).

[0105] Preferably, there are multiple sets of connecting grooves (46), which are arranged non-equidistantly along the height direction of the sorting bin (16). Each set contains two connecting grooves (46), which are symmetrically placed on the front and rear inner sides of the sorting bin (16). The distance between two adjacent sets of connecting grooves (46) gradually increases from the bottom surface to the top surface of the sorting bin (16).

[0106] The fourth telescopic rod (48) is located below the connecting groove (46), and the plurality of fourth telescopic rods (48) and the plurality of connecting grooves (46) correspond one-to-one.

[0107] One end of the fourth telescopic rod (48) is placed on the left inner side of the sorting bin (16), and the side of the fourth telescopic rod (48) and the inner side of the sorting bin (16) are slidably in contact.

[0108] One end of the fixing connector (47) is placed at the other end of the fourth telescopic rod (48), and the other end of the fixing connector (47) is curved upward in an arc. The fixing connector (47) is made of an elastic and deformable material.

[0109] A folding shelf (44) is placed between the left and right inner sides of the sorting bin (16), and the width of the folding shelf (44) is equal to the inner width of the sorting bin (16).

[0110] Preferably, there are multiple sets of folded shelves (44), which are arranged non-equidistantly along the height direction of the sorting bin (16). The multiple sets of folded shelves (44) correspond one-to-one with the multiple sets of connecting grooves (46). There are multiple folded shelves (44) in each set. The length of the multiple folded shelves (44) after unfolding is equal to the inner length of the sorting bin (16). Two adjacent folded shelves (44) in the same set are hinged together. The leftmost folded shelf (44) in the same set is connected to the sorting bin (16). The left side is hinged to the right side, and the other end of the rightmost edge of the folded shelf (44) is hinged to the fixed connector (47). The two ends of the hinge of two adjacent folded shelves (44) in the same group are respectively provided with connecting blocks (45). The connecting blocks (45) correspond to the two connecting slots (46) in the same inner group. Multiple folded shelves (44) in the same group can be opened and closed in the sorting bin (16) by means of the connecting blocks (45) and the connecting slots (46) under the extension and retraction of the fourth telescopic rod (48).

[0111] Preferably, the connecting block (45) and the connecting groove (46) are fixed together by fastening bolts.

[0112] Preferably, the folded shelf (44) has a hollow structure, and the folded shelf (44) is filled with a mixture of sponge and foam particles.

[0113] Preferably, the two outermost folded panels (44) within the same group have sealing strips on their sides, the length of which is equal to the width of the folded panel (44).

[0114] Preferably, the bottom surface of the folded layer (44) is uniformly provided with multiple shock-absorbing ground contacts;

[0115] Preferably, the hierarchical structure and the control system of the intelligent sorting equipment establish signal interaction.

[0116] In use, the layered structure is installed on the intelligent sorting equipment. Initially, the folded shelf (44) is retracted to one side of the sorting bin (16). The sorting mechanism first conveys the express parcels with identifiable barcode information to the bottom of the sorting bin (16) via the second conveyor belt (17). The ultrasonic ranging module collects the height data of the express parcels inside the sorting bin (16) and sends the collected height data to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received image data and compares the height data with the preset height data 1. If they are equal, it sends an execution command to the controller to control the sorting bin. The device controls the extension of the fourth telescopic rod (48) at the bottom. The fourth telescopic rod (48) drives multiple folding shelves (44) in the same group to slide and unfold along the corresponding connecting grooves (46) through the connecting blocks (45) on both sides, so that the two outermost folding shelves (44) and the left and right inner sides of the sorting bin (16) come into contact. The express parcels that fall later fall onto the multiple folding shelves (44) in the same group, and so on. The express parcels are stored in layers through multiple sets of folding shelves (44), reducing the collision and impact between the express parcels and the express parcels that fall first on the lower layer, reducing the damage to the express parcels themselves and the express parcels on the lower layer, and also reducing the impact on the bottom surface of the sorting bin (16), reducing the damage to the sorting bin (16). Example 2

[0117] The difference between this embodiment and embodiment 1 is that: the folding shelf (44) has a through hole in the middle, the edge of the net (49) is connected to the edge of the through hole, and the net (49) is made of rubber; when in use, when the express package falls on the net (49) and collides with the net (49), the rubber net (49) can effectively absorb and disperse the impact force, reduce the damage to the express package, and also reduce the impact on the folding shelf (44), thus extending the service life of the folding shelf (44); Example 3

[0118] The difference between this embodiment and embodiment 1 is that: a rubber strip (50) is placed on the top surface of the folding shelf (44), the rubber strip (50) is equal to the width of the folding shelf (44), there are multiple rubber strips (50), and the multiple rubber strips (50) are arranged without spacing along the length direction of the top surface of the folding shelf (44); when in use, when a courier package falls onto the folding shelf (44) and collides with the folding shelf (44), the rubber strip (50) can effectively absorb and disperse the impact force, reduce the damage to the courier package, and also reduce the impact on the folding shelf (44), thus extending the service life of the folding shelf (44);

[0119] The design of the distance between two adjacent sets of the connecting grooves (46) gradually increases from the bottom surface to the top surface of the sorting bin (16). When the express parcel falls on the bottom surface of the sorting bin (16) or the folded shelf (44) near the bottom surface of the sorting bin (16), the falling distance is long under the action of gravity, which causes a greater impact on the folded shelf (44), the express parcel itself and the express parcel that falls first. The folded shelf (44) with a smaller distance near the bottom surface of the sorting bin (16) can reduce the impact on the express parcel that has already fallen when the falling distance is large, and reduce the damage to the express parcel that has already fallen.

[0120] The fixed connector (47) is made of an elastic and deformable material. The folding plate (44) on the far right edge can be unfolded or folded by the fourth telescopic rod (48) driven by the fixed connector (47).

[0121] The folding shelf (44) is a hollow structure. The design of filling the folding shelf (44) with a mixture of sponge and foam particles can reduce the weight of the folding shelf (44), reduce the extension resistance of the fourth telescopic rod (48), and effectively absorb and disperse the impact force, improve the shock absorption and buffering performance of the folding shelf (44), improve the support capacity of the folding shelf (44) for express parcels, and reduce the deformation of the folding shelf (44).

[0122] The two outermost folding shelves (44) in the same group are provided with sealing strips on their sides. The length of the sealing strips is equal to the width of the folding shelves (44). This design can increase the friction between the folding shelves (44) and the inner side of the sorting bin (16), which helps to reduce the shaking and displacement of the folding shelves (44) after being impacted by express parcels and the wear on the inner side of the sorting bin (16).

[0123] The bottom surface of the folded shelf (44) is evenly provided with multiple shock-absorbing ground contacts. The upper folded shelf (44) is in contact with the topmost express package that falls first from the lower layer. The shock-absorbing ground contacts can play a buffering role when the express package falls on a set of folded shelves (44) on the upper layer, reducing the deformation and wear of the folded shelf (44), and at the same time reducing the damage caused by the collision impact on the express package that falls first from the lower layer.

[0124] It should be noted that the layered folding protective structure is only applicable to the following intelligent sorting equipment;

[0166] Preferably, an ultrasonic ranging module is placed on the top surface of the sorting cylinder.

[0168] The transmission mechanism is located between two adjacent bases (15).

[0169] There are two support legs (11), and the tops of the support legs (11) are respectively positioned on the side of the side panel (12).

[0170] A main second rotating roller and multiple slave second rotating rollers are disposed between the two side baffles (12).

[0172] The two ends of the U-shaped support rod (40) are respectively placed on the sides of the two side baffles (12). The U-shaped support rod (40) is located above the first conveyor belt (10) and close to the other end of the first conveyor belt (10). A reader (41) is placed in the middle of the inner top surface of the U-shaped support rod (40).

[0173] Preferably, the intelligent sorting equipment further includes a control system, which comprises a signal converter, a data processor, and a controller.

[0174] The signal converter is placed on the bracket (1), the data processor is placed on the bracket (1), and the controller is placed on the bracket (1).

[0175] The camera (6), the reader (41), and the signal converter are connected via a data cable.

[0176] The first telescopic rod (9), the second telescopic rod (21), the third telescopic rod (4), the rotary motor, the first steering motor, the second steering motor, and the drive motor are connected to the controller via a data transmission line.

[0177] The signal converter is connected to the data processor via a data transmission line, and the data processor is connected to the controller via a data transmission line.

[0178] The signal converter can convert the electrical signals of the image data collected by the camera (6) and the barcode data of the express package collected by the reader (41) into digital signals.

[0179] The controller can be implemented by one or more application-specific integrated circuits (ASICs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components to execute instructions from a data processing device.

[0180] The data processor and the signal converter exchange information.

[0181] When the control system is executed, it mainly performs the following steps:

[0182] Before sorting express parcels, the control system pre-sets the destination of each express parcel corresponding to each U-shaped baffle (27). For example, U-shaped baffle 1 (27) corresponds to Jiangsu Province, U-shaped baffle 2 (27) corresponds to Shaanxi Province, U-shaped baffle 3 (27) corresponds to Zhejiang Province, and so on. Multiple U-shaped baffles (27) correspond one-to-one with multiple sorting bins (16). For example, express parcels on U-shaped baffle 1 (27) are sorted into sorting bin 1 (16), express parcels on U-shaped baffle 2 (27) are sorted into sorting bin 2 (16), express parcels on U-shaped baffle 3 (27) are sorted into sorting bin 3 (16), and so on. The rotational speed of the drive motor and the rotational speed of the second rotating motor are such that when the express package reaches one end of the first conveyor belt (10), the U-shaped baffle (27) corresponding to the express package can rotate to the position corresponding to one end of the first conveyor belt (10), so that the express package can be transferred from the first conveyor belt (10) to the second conveyor belt (17) of the U-shaped baffle (27). Multiple U-shaped baffles (27) correspond one-to-one with multiple cameras (6), for example: U-shaped baffle 1 (27) corresponds to camera 1 (6), U-shaped baffle 2 (27) corresponds to camera 2 (6), U-shaped baffle 2 (27) corresponds to camera 2 (6)...,

[0183] During the sorting of express parcels, the parcels are placed on the first conveyor belt (10) with spacing for transport, and the reader (41) collects the barcode data on the parcels.

[0184] When the barcode reader can collect the barcode data of the express package, it sends the collected barcode data to the signal converter. The signal converter converts the electrical signal of the received barcode data into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received barcode data, identifies the destination of the express package in the barcode data, finds the U-shaped baffle (27) corresponding to the destination, and the controller controls the drive motor to rotate. The drive motor controls the drive turntable (26) to rotate. The drive turntable (26) drives the driven turntable (23) to rotate. The driven turntable (23) drives the collection cylinder, the connecting disc (31), and multiple U-shaped baffles (27) to rotate, so that the U-shaped baffle (27) corresponding to the express package rotates and approaches the first conveyor belt. 10) The express package is transported from the first conveyor belt (10) to the second conveyor belt (17) on the U-shaped baffle (27). When the U-shaped baffle (27) rotates to be close to the corresponding sorting bin (16), the controller controls the first rotating motor (22) corresponding to the U-shaped baffle (27) to start. The first rotating motor (22) drives the first meshing gear (18) to rotate. The first meshing gear (18) drives the second meshing gear (19) to rotate. The second meshing gear (19) drives the second conveyor belt (17) to rotate. The second conveyor belt (17) transports the express package to the corresponding sorting bin (16). This process is repeated to sort express packages whose barcode destination can be identified by the reader (41) into the corresponding sorting bin (16).

[0185] When the barcode reader cannot collect the barcode data of the express package, and the control system cannot identify the destination in the barcode data, the controller controls multiple cameras (6) to start. The express package is conveyed from the first conveyor belt (10) to the second conveyor belt (17) of any U-shaped baffle (27). The camera (6) collects images of the express package on each U-shaped baffle (27) and sends the collected image data signal to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor processes the digital signal of the received image data and identifies the barcode in the image data. When the barcode cannot be identified, the controller controls the drive motor to stop rotating. The controller controls the second telescopic rod (21) and the third telescopic rod (4) on the support crossbar where the camera (6) is located to start. The retracting rod (21) retracts towards the U-shaped baffle (27), and the third telescopic rod (4) extends downward, causing the first telescopic rod (9) and the first gripper (34) to move to the top of the express package. The controller controls the first telescopic rod (9) to start, and the first telescopic rod (9) extends downward, causing the two first grippers (34) to clamp the express package. Then the controller controls the third telescopic rod (4) to retract upward, and the second telescopic rod (21) retracts towards the collection bin (24), causing the first telescopic rod (9) and the first gripper (34) to move above the collection bin (24). The controller controls the first telescopic rod (9) to retract upward, causing the two first grippers (34) to separate and put the express package into the collection bin (24). This process is repeated to sort express packages whose barcode destination cannot be identified by the reader (41) into the collection bin (24) for subsequent re-sorting. Example 4

[0186] The difference between this embodiment and embodiment 1 is that: a flexible sheet (42) is placed on the other side of the first gripper (34), and the flexible sheet (42) has anti-slip patterns, including horizontal anti-slip patterns and vertical anti-slip patterns, which are arranged alternately; when in use, the flexible sheet (42) can increase the friction between the first gripper (34) and the express package, reduce the slippage of the express package caused by the first gripper (34) moving into the collection bucket (24), and at the same time protect the express package, reducing the damage to the express package caused by the first gripper (34) puncturing the express package; Example 5

[0187] The difference between this embodiment and embodiment 1 is that: a rubber pad (43) is placed on the second conveyor belt (17), and there are multiple rubber pads (43), with each of the multiple rubber pads (43) corresponding to a multiple second conveyor belt (17); when in use, the rubber pad (43) can increase the friction between the second conveyor belt (17) and the express package, reducing the chance of the express package slipping off the second conveyor belt onto the ground or into the mismatched collection bin (24) under the action of the centrifugal force of the rotating mechanism, thus preventing damage to the express package or sorting errors;

[0188] The collection bucket (24) is detachably placed on the inner bottom surface of the two U-shaped support arms (30). The top surface of the collection bucket (24) and the inner side edge of the connecting disc (31) are detachably connected. The side edge of the collection bucket (24) and the inner side edge of the driven turntable (23) are detachably connected. The top surface of the collection bucket (24) is designed with an ultrasonic ranging module. The ultrasonic ranging module can monitor the internal condition of the collection bucket (24) in real time. When the collection bucket (24) is full, the ultrasonic ranging module sends a signal to the terminal to remind the staff to transfer the express parcels in the collection bucket (24) in time. The detachable connection method can facilitate the transfer of express parcels in the collection bucket (24).

[0189] The design of one end of the first conveyor belt (10) being close to the connecting disc (31) and having a small gap between it and the second conveyor belt (17) enables the rotating mechanism to rotate normally, while also enabling the express parcels on the first conveyor belt (10) to be transferred to the second conveyor belt (17), thus preventing the express parcels from falling to the ground through the gap between the two, which would result in damage and loss of the express parcels.

[0190] The design of the U-shaped baffle (27) enables the express parcels on the second conveyor belt (17) to enter different sorting bins (16) under the transmission of the first meshing gear (18) and the second meshing gear (19), thereby realizing the sorting and storage of express parcels. At the same time, it can limit the express parcels on the second conveyor belt (17) to prevent express parcels with identifiable barcode information from entering the collection bin (24) under the action of the centrifugal force of the rotating mechanism, which would lead to sorting errors and reduce sorting efficiency and accuracy.

[0191] The design of the first telescopic rod (9), the second telescopic rod (21) and the third telescopic rod (4) is such that the second telescopic rod (21) can provide power to the first sliding block (7), so that the first sliding block (7) drives the clamping mechanism to slide along the first sliding groove (20) to reach the top of the express package or the top of the collection bin (24). The third telescopic rod (4) can make the first hook approach or move away from the express package. The first telescopic rod (9) can make the first hook clamp or release the express package, and put the express package that cannot be identified by barcode information into the collection bin (24).

[0192] The design of the second sliding groove (32), the second sliding block (33) and the rotating shaft (29) together enables the collection bucket (24), the driven turntable (23) and the connecting disc (31) to rotate on the top surface of the bottom plate (13) under the support of the two U-shaped support arms (30);

[0193] The design of the sorting mechanism and the gripping mechanism is such that express parcels with barcodes can be sorted into different sorting bins (16), while express parcels without barcodes can be sorted into collection bins (24), which can improve the efficiency and accuracy of express parcel sorting.

[0194] The design of the sorting mechanism and the rotating mechanism in combination enables the sorting mechanism to rotate and approach the first conveyor belt (10) under the drive of the rotating mechanism, so that express parcels with barcodes that can be identified on the first conveyor belt (10) enter the corresponding U-shaped baffle (27). At the same time, the sorting mechanism can rotate and approach the corresponding sorting bin (16), so that express parcels with barcodes that can be identified enter the corresponding sorting bin (16), thereby realizing the sorting of express parcels.

[0195] The goal is to enable the transmission mechanism to identify the barcode information of express parcels, and to sort the express parcels with identifiable barcode information into the corresponding classification bins (16) according to their destinations through the sorting mechanism, and to sort the express parcels with unidentifiable barcode information into the collection bins (24) through the clamping mechanism.

[0196] It should be noted that, unless otherwise explicitly specified and limited, the terms "placed," "connected," and "linked" should be interpreted broadly. For example, they can refer to fixed connections such as folded joints, riveted joints, pinned joints, adhesive joints, and welded joints; detachable connections such as threaded joints, snap-fit ​​joints, and hinged joints; integral connections; electrical connections; direct connections; indirect connections via an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0197] It should be further noted that, in order to keep the description simple and clear, the above specific embodiments only describe the differences between them and other embodiments. However, those skilled in the art should know that the above specific embodiments are also independent technical solutions.

Claims

1. A layered folding protective structure for intelligent sorting equipment, characterized in that: It consists of a sorting bin, a folding shelf, a connecting block, a connecting groove, a fixing connector, and a fourth telescopic rod. The sorting bin has an open top surface, and an ultrasonic ranging module is placed on the top surface of the sorting bin. A connecting groove is opened on the inner side of the sorting bin, and the fourth telescopic rod is placed below the connecting groove. Multiple fourth telescopic rods correspond one-to-one with multiple connecting grooves. One end of the fourth telescopic rod is placed on the left inner side of the sorting bin, and the side of the fourth telescopic rod is slidably in contact with the inner side of the sorting bin. One end of the fixing connector is placed on the other end of the fourth telescopic rod. A folding shelf is placed between the left and right inner sides of the sorting bin. In use, the layered folding protective structure is installed on the intelligent sorting equipment. Initially, the folding shelves are retracted to one side of the sorting bin. The sorting mechanism first conveys the barcode-identifiable express packages to the bottom of the sorting bin via the second conveyor belt. The ultrasonic ranging module collects the height data of the express packages inside the sorting bin and sends the collected height data to the signal converter. The signal converter converts the electrical signal of the received image data signal into a digital signal and sends it to the data processor. The data processor processes the received digital signal of the image data and compares the height data with the preset height data 1. If the ratio is equal, an execution command is sent to the controller. The controller then extends the fourth telescopic rod at the bottom. This fourth telescopic rod causes multiple folding shelves within the same group to slide open along the corresponding connecting slots via the connecting blocks on both sides. This causes the two outermost folding shelves to contact the left and right inner sides of the sorting bin. Packages falling later then land on these multiple folding shelves within the same group, and so on. This multi-layered folding shelf system allows for layered storage of packages, reducing collisions and impacts between packages and those falling earlier, minimizing damage to the packages themselves and those below. It also reduces damage to the bottom surface of the sorting bin. To reduce impact and damage to the sorting bins, adjacent folding shelves in the same group are hinged together. The outermost left folding shelf in the same group is hinged to the left side of the sorting bin, and the outermost right folding shelf is hinged to the other end of the fixed connector. Connecting blocks are respectively placed at the two ends of the hinge point of two adjacent folding shelves in the same group. The connecting blocks correspond to two connecting slots in the same group. Multiple folding shelves in the same group can be opened and closed in the sorting bin by the extension and retraction of the fourth telescopic rod through the connecting blocks and the connecting slots.

2. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The folded layer has a through hole in the middle, and the edge of the mesh is connected to the edge of the through hole. The mesh is made of rubber.

3. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The top surface of the folded shelf is provided with rubber strips, the rubber strips being equal to the width of the folded shelf, and there are multiple rubber strips arranged without spacing along the length direction of the top surface of the folded shelf.

4. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The connecting slots are in multiple sets, and these sets are arranged non-equidistantly along the height of the sorting bin. Each set contains two connecting slots, which are symmetrically placed on the front and rear inner sides of the sorting bin. The distance between adjacent sets of connecting slots gradually increases from the bottom to the top of the sorting bin. When a package falls onto the bottom of the sorting bin or onto a folded shelf near the bottom, the long distance it falls under the influence of gravity results in a greater impact on the folded shelf, the package itself, and the package that falls first. Folded shelves with smaller spacing near the bottom of the sorting bin can reduce the impact on the fallen package when the falling distance is greater, thus reducing damage to the fallen package.

5. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The other end of the fixed connector is curved upward in an arc. The fixed connector is made of an elastic and deformable material. The folded layer on the far right edge can be unfolded or folded by the fourth telescopic rod under the action of the fixed connector.

6. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The width of the folded shelf is equal to the inner width of the sorting bin. There are multiple sets of folded shelves, which are arranged non-equidistantly along the height direction of the sorting bin. The multiple sets of folded shelves correspond one-to-one with the multiple sets of connecting slots. Each set contains multiple folded shelves, and the length of the multiple folded shelves after unfolding is equal to the inner length of the sorting bin.

7. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The connecting block and the connecting groove are fixed together by fastening bolts. The folding shelf is a hollow structure and is filled with a mixture of sponge and foam particles, which can reduce the weight of the folding shelf, reduce the extension resistance of the fourth telescopic rod, and effectively absorb and disperse impact force, improve the shock absorption and buffering performance of the folding shelf, improve the support capacity of the folding shelf for express parcels, and reduce the deformation of the folding shelf.

8. The layered folding protective structure for an intelligent sorting device according to claim 1, characterized in that... The two outermost folding shelves in the same group have sealing strips on their sides, the length of which is equal to the width of the folding shelf. This increases the friction between the folding shelf and the inner side of the sorting bin, helping to reduce the shaking and displacement of the folding shelf after being impacted by express packages and the wear on the inner side of the sorting bin. The bottom surface of the folding shelf is evenly covered with multiple shock-absorbing ground contacts. The upper folding shelf contacts contact the topmost express package that falls first in the lower layer. The shock-absorbing ground contacts can buffer when the express package falls on the upper set of folding shelves, reducing the deformation and wear of the folding shelf, and at the same time reducing the damage caused by the impact of the express package that falls first in the lower layer.
