Description

Technical Field

[0001] This invention relates to the field of logistics sorting technology, specifically a sorting device for logistics supply chain. Background Technology

[0002] Logistics sorting machines are core automated equipment in the logistics supply chain that enables automatic classification and directional transportation of goods. Through the synergy of mechanical structure, sensing technology and control logic, they accurately divert goods of different destinations and specifications from the main conveyor line to designated channels. They are widely used in e-commerce warehousing, express delivery transit, manufacturing and other scenarios. Their core value is to replace manual sorting, improve efficiency, and reduce missorting rate and labor costs.

[0003] However, in practical use, we have found that existing sorting devices often require manual intervention from staff to place each document bag individually on the conveyor line due to the thinness and large quantity of the bags. This reduces sorting efficiency and easily causes overlapping or jamming, affecting the accuracy of subsequent identification and sorting. Especially during peak hours, document bags tend to stack, causing the barcodes on the obscured bags to be unable to be accurately read by the identification system, leading to missorting or omissions, and in severe cases, causing blockages in the conveyor line. To address this, we propose a sorting device for the logistics supply chain. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to improve the automated feeding efficiency of lightweight items such as document bags, avoid manual intervention and stacking during delivery, and ensure that each document bag remains independent and flat during transportation, thereby improving barcode recognition rate and sorting accuracy.

[0005] To address the aforementioned technical problems, this application provides a sorting device for a logistics supply chain, including a conveying system, document bags, a scanning system, and a workbench disposed on one side of the conveying system for placing the document bags, and further comprising:

[0006] There are two push rollers, both of which are positioned above the document bag and respectively attached to the top two sides of the document bag;

[0007] There are two roll-out rollers, both of which are located above the worktable and on the side of the document bag closest to the conveying system.

[0008] A pusher assembly is provided on the workbench. The pusher assembly drives the two pusher rollers to rotate synchronously in opposite directions, thereby pushing the two sides of the uppermost file bag towards the two roll-out rollers.

[0009] A roll-out assembly is arranged above the workbench, and the roll-out assembly is used to drive the two roll-out rollers to rotate, so that the file bags on the workbench are transmitted one by one to above the conveying system through the rotating roll-out rollers.

[0010] In some embodiments, the two push rollers and the two roll-out rollers are made of rubber, and grooves are formed on the outer sides of the two push rollers and the two roll-out rollers.

[0011] In some embodiments, the push assembly includes a feeding member arranged on the workbench, which is used to push the file bags upward to ensure timely replenishment of the file bags. A driving member is arranged above the workbench, which is used to generate power required for synchronous reverse rotation of the two push rollers, so that the two push rollers drive the uppermost file bag to move towards the two roll-out rollers. An angle adjusting member is arranged above the workbench, which is used to synchronously and reversely adjust the angle of the two push rollers, so that the two push rollers are suitable for file bags of different specifications.

[0012] In some embodiments, the feeding member includes a feeding bin arranged in the workbench, which penetrates through the workbench and is located on the same axis as the workbench.

A driving rod is rotatably arranged at the top of the feeding bin, and a driving groove is formed in the driving rod to cooperate with the first insertion rod. A transmission gear is arranged on the outer side of the driving rod to engage with the driving gear.

[0014] In some embodiments, the angle adjusting member includes adjusting rings rotatably disposed on the outer sides of the two pushing rollers, adjusting shafts rotatably disposed on one side of each of the two adjusting rings, and adjusting shafts rotatably disposed on the top of the feeding hopper. Adjusting discs are disposed at the ends of the two adjusting shafts away from the two adjusting rings. Synchronizing rods are disposed on the sides of the two adjusting discs away from the two adjusting shafts, and the two synchronizing rods are located away from the axes of the two adjusting discs and on the same horizontal line. Adjusting screws are rotatably disposed on the top of the feeding hopper, adjusting handles are disposed on the top of the adjusting screws, and synchronizing plates are disposed on the outer side of the adjusting screws. The synchronizing plates are threadedly connected to the adjusting screws, and synchronizing grooves are opened at both ends of the synchronizing plates. The two synchronizing rods are slidably disposed in the corresponding synchronizing grooves.

[0015] In some embodiments, the roll-out assembly includes a power unit disposed above the worktable, which, in conjunction with the document bag, drives two roll-out rollers to rotate synchronously in opposite directions, thereby driving adjacent document bags into the upper part of the conveying system. An expansion member is disposed above the worktable, which drives the two roll-out rollers to adapt to document bags of different thicknesses. A limit member is disposed in the feeding bin, which drives the document bags to leave the feeding bin one by one, thereby limiting the number of document bags conveyed.

[0016] In some embodiments, the power component includes a power motor mounted on the worktable, a power gear mounted at the output end of the power motor, a fixed plate mounted on the worktable, a sliding groove formed in the fixed plate, a sliding plate slidably mounted in the sliding groove, a fixed shaft rotatably mounted in the sliding plate, an auxiliary gear mounted at the end of the fixed shaft away from the sliding plate, an auxiliary spring mounted at the bottom of the sliding plate, and the bottom end of the auxiliary spring mounted at the bottom of the sliding groove. Of the two winding rollers, the lower winding roller has a winding gear mounted at one end, and a transmission belt is mounted on the outer side of the winding gear, the auxiliary gear, and the power gear. The transmission belt has toothed grooves that cooperate with the winding gear, the auxiliary gear, and the power gear.

[0017] In some embodiments, the expansion member includes two support plates disposed on the worktable, the two support plates being located on both sides of the discharge port, one of the two roll-out rollers being rotatably disposed at both ends within the two support plates, each of the two support plates having an expansion groove, an expansion plate being slidably disposed within each of the two expansion grooves, an expansion spring being disposed at the bottom of each of the two expansion plates, the bottom ends of each of the two expansion springs being disposed at the bottom of the corresponding expansion groove, and one of the two roll-out rollers being rotatably disposed at both ends within the two expansion plates and slidably disposed within the two support plates.

[0018] In some embodiments, the limiting member includes a limiting plate slidably disposed within the feeding hopper, and the limiting plate is located within the discharge port. The side of the limiting plate facing the document bag is arc-shaped. Connecting rods are provided at both ends of the limiting plate. Both connecting rods are slidably disposed within the feeding hopper. A horizontal plate is provided at the top of the two connecting rods. A limiting screw is rotatably disposed at the top of the feeding hopper, and the horizontal plate is threadedly connected to the limiting screw. A limiting handle is provided at the top of the limiting screw.

[0019] This invention has at least the following beneficial effects:

[0020] 1. The angle adjustment component allows for simultaneous reverse adjustment of the angles of the two push rollers, while the expansion component adaptively adjusts the distance between the two roll-out rollers. Combined with the adjustable design of the limiting component, it can accommodate document bags of different sizes and thicknesses. The push rollers and roll-out rollers are made of rubber with grooves, which enhances the friction with the document bags and prevents damage during transport. It is suitable for sorting document bags of various materials. The push component drives the two push rollers to rotate synchronously in opposite directions, and the roll-out component works in conjunction to achieve synchronous reverse rotation of the roll-out rollers, forming a continuous transmission of push and roll-out. This ensures that document bags are transported to the conveyor system one by one in an orderly manner, reducing jamming or accumulation.

[0021] 2. This sorting device achieves a high degree of automation in document bag sorting through the coordinated design of the pushing component and the roll-up component, significantly reducing manual intervention. The feeding spring in the feeding component continuously pushes the document bags upwards, and together with the feeding port below and the pedal replenishment structure, it can provide both batch stacking replenishment and emergency rapid replenishment, ensuring a timely and uninterrupted supply of document bags. The drive component drives the two pushing rollers to rotate synchronously in opposite directions through the transmission of motor, gears and universal joints, accurately pushing the top document bag toward the roll-up roller. The entire device does not require manual stacking and can operate continuously for a long time, effectively improving the throughput of logistics sorting, and is especially suitable for high-frequency, large-volume document sorting scenarios.

[0022] 3. Multiple structural designs ensure sorting accuracy while reducing usage and maintenance costs. The curved limiting plate of the limiting component strictly restricts the transport of document bags one by one, avoiding sorting errors caused by simultaneous transport of multiple bags from the source. Its curved surface guides the movement direction of the next document bag, preventing folding damage due to compression. The push rollers rotate synchronously in opposite directions against the top sides of the document bag, and the roll-up rollers precisely connect to the conveying system. The fixed transmission path ensures that the document bag falls stably to the designated position, reducing offset errors. The rubber roller body and groove design enhance transmission friction while effectively preventing wrinkles and damage to the edges of the document bags, reducing sorting losses. The core transmission structure uses mature and common components such as gears and transmission belts, combined with a spring automatic adaptation mechanism, ensuring stable operation and a low failure rate. It is also easy to disassemble and maintain. The entire system ensures sorting accuracy of one bag per roller while reducing equipment operating and maintenance costs, balancing sorting quality and economic efficiency.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-4 The present invention provides a technical solution: a sorting device for a logistics supply chain, comprising a conveying system 1, a document bag 2, a scanning system 3, and a workbench 4 disposed on one side of the conveying system 1 for placing the document bag 2, and further comprising:

[0038] There are two push rollers 5, both of which are positioned above the document bag 2 and are respectively attached to the top two sides of the document bag 2;

[0039] There are two roll-out rollers 6, both of which are located above the worktable 4 and are positioned on the side of the document bag 2 closest to the conveying system 1.

[0040] The push assembly 7 is set on the workbench 4. The push assembly 7 drives the two push rollers 5 to rotate synchronously in opposite directions, thereby pushing the two sides of the uppermost file bag 2 through the two push rollers 5, so that it moves towards the two roll-out rollers 6.

[0041] The roll-out assembly 8 is located above the workbench 4. The roll-out assembly 8 drives two roll-out rollers 6 to rotate, thereby transferring the document bags 2 on the workbench 4 one by one to the top of the conveyor system 1 through the rotating roll-out rollers 6.

[0042] Both push rollers 5 and both roll-out rollers 6 are made of rubber, and grooves 9 are provided on the outer side of both push rollers 5 and both roll-out rollers 6. The rubber material can increase the friction with the document bag 2, and the grooves 9 further enhance the grip, ensuring that the document bag 2 does not slip or deviate when the push rollers 5 push the document bag 2 and the roll-out rollers 6 transfer the document bag 2, thus providing a stable contact basis for power transmission.

[0043] The pushing component 7 includes a feeding component 10 mounted on the workbench 4, which pushes the document bag 2 upwards to ensure timely replenishment. A driving component 11 is mounted above the workbench 4 to generate the power required for the synchronous and reverse rotation of the two pushing rollers 5, thereby driving the uppermost document bag 2 toward the two roll-out rollers 6. An angle adjusting component 12 is mounted above the workbench 4 to synchronously and reversely adjust the angles of the two pushing rollers 5, making them suitable for document bags 2 of different sizes.

[0044] The feeding component 10 includes a feeding bin 101 disposed within the workbench 4. The feeding bin 101 penetrates the workbench 4 and is coaxial with the workbench 4. A feeding trough 102 is provided inside the feeding bin 101. An inlet 103 is provided on the side of the feeding bin 101 away from the conveying system 1, and the inlet 103 is located below the workbench 4. An outlet 104 is provided on the side of the feeding bin 101 closer to the conveying system 1, and the outlet 104 is located above the workbench 4. The inlet 103 communicates with the outlet 104 through the feeding trough 102. A feeding trough 102 is slidably disposed within the feeding bin 102. The material plate 105 and the document bag 2 are both located above the material plate 105. Two feeding rods 106 are installed at the bottom of the material plate 105, and two feeding springs 107 are also installed at the bottom of the material plate 105. The other ends of each spring are located at the bottom of the feeding trough 102, and the two feeding springs 107 are located outside the two feeding rods 106 respectively. The two feeding rods 106 pass through and slide at the bottom of the feeding bin 101. A pedal 108 is installed at the lower end of the two feeding rods 106. When a foot is placed on the pedal 108 and then pressed down, the pedal 108 will drive the feeding rods 106 at both ends. The feed rod 106 moves downward together with the feed plate 105, causing it to slide within the feed hopper 101. As the feed rod 106 slides downward, the feed plate 105 at the top of the feed rod 106 slides downward along with it into the feed trough 102. During this process, the feed spring 107 is in a compressed and stored state until it can no longer be compressed, and the feed inlet 103 is connected to the feed trough 102. At this point, the stacked document bags 2 can be placed on the feed plate 105. After releasing the pedal 108, the feed spring 107 rebounds, pushing the feed plate 105 upward. The movement causes the feeding plate 105 to move the document bag 2 upwards until the uppermost document bag 2 touches the top of the feeding trough 102. It should be noted that the inner wall of the feeding trough 101 is coated with an anti-friction coating to reduce the resistance between the document bag 2 and the inner wall, ensuring smooth feeding and discharging, and avoiding scratches on the document bag 2. The feeding spring 107 automatically resets to replace frequent manual placement, reducing manual intervention and labor intensity. Its function is to ensure that the workbench 4 always has a sufficient number of document bags 2, avoiding sorting interruptions due to material shortages and improving continuous operation capability.

[0045] The driving component 11 includes a drive motor 111 mounted on the top of the feeding hopper 101. A drive gear 112 is mounted on the output end of the drive motor 111. Universal joints 113 are mounted on opposite ends of the two push rollers 5. A first insert rod 114 and a second insert rod 115 are respectively mounted on opposite ends of the two universal joints 113, with the second insert rod 115 slidably mounted within the first insert rod 114. Both the first insert rod 114 and the second insert rod 115 are rectangular. A drive rod 116 is rotatably mounted on the top of the feeding hopper 101, and a groove is formed within the drive rod 116 that cooperates with the first insert rod 114. The drive groove 117 is used, and a transmission gear 118 that meshes with the drive gear 112 is provided on the outer side of the drive rod 116. The drive motor 111 drives the drive gear 112 at its output end to rotate, and the drive gear 112 drives the transmission gear 118 that meshes with it to rotate together during the rotation. When the transmission gear 118 rotates, the drive rod 116 located at the axis of the transmission gear 118 will rotate together with the transmission gear 118, so that the drive rod 116 drives the first insertion rod 114 to rotate through the drive groove 117 at its axis. When the insertion rod 114 rotates, the second insertion rod 115, which is slidably disposed within the first insertion rod 114, will rotate along with it. This causes the universal joints 113, which are respectively disposed at opposite ends of the first insertion rod 114 and the second insertion rod 115, to rotate. During the rotation of the two universal joints 113, power is transmitted to the corresponding push rollers 5, causing the two push rollers 5 to rotate within the corresponding adjusting rings 121. This, in turn, smoothly pushes the uppermost document bag 2 to the discharge port 104. During the pushing process, the two push rollers 5 continuously apply uniform pressure to ensure the document bag... 2. The conveyor is centered and does not deviate. The first insertion rod 114 and the second insertion rod 115 can freely extend and retract to adapt to the change of the deflection angle of the adjustment ring 121 during the rotation of the adjustment shaft 122 driven by the adjustment disc 123. While maintaining effective power transmission, it ensures that the push roller 5 can still be driven stably under different inclination states. Its function is that the rectangular first insertion rod 114 and the second insertion rod 115 can avoid power transmission slippage. With the cooperation of the universal joint 113, it ensures that the push roller 5 can still rotate synchronously after the angle changes, ensuring that the force on both sides of the document bag 2 is uniform.

[0046] The angle adjusting component 12 includes adjusting rings 121 rotatably disposed on the outer sides of the two push rollers 5. An adjusting shaft 122 is rotatably disposed on one side of each of the two adjusting rings 121, and both adjusting shafts 122 are rotatably disposed on the top of the feeding hopper 101. An adjusting disc 123 is disposed at the end of each adjusting shaft 122 away from the two adjusting rings 121. A synchronizing rod 124 is disposed on the side of each adjusting disc 123 away from the two adjusting shafts 122, and both synchronizing rods 124 are located away from the axis of the two adjusting discs 123 and are on the same horizontal line. An adjusting disc 124 is rotatably disposed on the top of the feeding hopper 101. The adjusting screw 125 has an adjusting handle 126 at its top and a synchronizing plate 127 on its outer side. The synchronizing plate 127 is threadedly connected to the adjusting screw 125. Both ends of the synchronizing plate 127 have synchronizing grooves 128, and two synchronizing rods 124 are slidably disposed within their respective synchronizing grooves 128. After adjusting the position of the limiting plate 151, the angles of the two pushing rollers 5 also need to be adjusted. To adjust the angle of the pushing rollers 5, the adjusting handle 126 is rotated, causing the adjusting handle 126 to drive the adjusting screw 125 to rotate. When 125 rotates, the synchronous plate 127, which is threaded to it, will move up and down under the limiting action of the two synchronous rods 124. When the synchronous plate 127 moves up and down, it will drive the two synchronous rods 124 to move up and down synchronously through the synchronous groove 128, thereby causing the adjusting discs 123, which are respectively set at one end of the two synchronous rods 124, to rotate. Under the action of the two adjusting shafts 122, the two adjusting discs 123 rotate around their corresponding adjusting shafts 122, thereby driving the two adjusting shafts 122 to rotate synchronously in opposite directions. When the two adjusting shafts 122 rotate synchronously in opposite directions... The two adjusting shafts 122 will drive the corresponding adjusting rings 121 at one end to rotate together, thereby driving the angle of the two push rollers 5 to change through the two adjusting rings 121. When the outer sides of the two push rollers 5 contact the two sides of the uppermost document bag 2 and apply appropriate pressure, the rotation of the adjusting handle 126 can be stopped. The angle of the two push rollers 5 can be adjusted synchronously by simply rotating the adjusting handle 126. The operation is convenient, and the push rollers 5 can be adapted to document bags 2 of different widths. Multiple specifications of materials can be processed without changing the equipment, improving compatibility and reducing the equipment investment cost of enterprises.

[0047] The roll-out assembly 8 includes a power unit 13 located above the workbench 4. The power unit 13, in conjunction with the document bag 2, drives two roll-out rollers 6 to rotate synchronously in opposite directions, thereby driving the adjacent document bag 2 into the upper part of the conveying system 1. An expansion member 14 is provided above the workbench 4. The expansion member 14 drives the two roll-out rollers 6 to adapt to document bags 2 of different thicknesses. A limit member 15 is provided in the feeding bin 101. The limit member 15 drives the document bags 2 to leave the feeding bin 101 one by one, thereby limiting the number of document bags 2 conveyed.

[0048] The power component 13 includes a power motor 131 mounted on the workbench 4, with a power gear 132 at the output end of the power motor 131. A fixed plate 133 is mounted on the workbench 4, and a sliding groove 134 is formed within the fixed plate 133. A sliding plate 135 is slidably mounted within the sliding groove 134, and a fixed shaft 136 is rotatably mounted within the sliding plate 135. An auxiliary gear 137 is mounted at the end of the fixed shaft 136 furthest from the sliding plate 135. An auxiliary spring 138 is mounted at the bottom of the sliding plate 135, with its bottom end positioned at the bottom of the sliding groove 134. Of the two winding rollers 6, the lower winding roller 6 has a winding gear 139 at one end, and the winding gear 139, the auxiliary gear 137, and the power gear 132 are connected by a transmission mechanism. The transmission belt 1310 has grooves 1311 inside that cooperate with the winding gear 139, auxiliary gear 137, and power gear 132. After the document bag 2 reaches the discharge port 104 under the action of the two push rollers 5, the document bag 2 will be discharged through the area between the top of the adjusted limit plate 151 and the top of the discharge port 104, and squeezed into one side of the two winding rollers 6. At this time, the drive motor 111 is stopped and the power motor 131 is started. When the power motor 131 starts, it will drive the power gear 132 at its output end to rotate. The power gear 132 will then drive the transmission belt 1310 to start running through the multiple grooves 1311. When the transmission belt 1310 moves under the action of the power gear 132... When the auxiliary gear 137 and the winding gear 139 mesh with it rotate together, the winding gear 139 drives the winding roller 6 at its shaft to rotate synchronously. As the winding roller 6 rotates, the document bag 2 is smoothly wound in and quickly discharged from the equipment, completing the discharge action. If the document bag 2 to be sorted is thicker, the upper winding roller 6 continues to rotate, while the lower winding roller 6, after being squeezed by the document bag 2, will drive the expansion plates 143 at both ends to slide downward into the corresponding expansion grooves 142. As the expansion plates 143 slide, the expansion spring 144 is compressed and stored, allowing the lower winding roller 6 to elastically yield downward to accommodate the thick bag. After the document bag 2 has completely passed through, the expansion spring 144... 44 releases stored energy, pushing the expansion plate 143 to rise, causing the lower roll-out roller 6 to return to its original position, ensuring stable clamping and transmission of subsequent standard thickness document bags 2. During this process, the auxiliary gear 137 remains in an upward-pressed state, ensuring that the sliding plate 135 is always in the extreme upward-pressed position within the sliding groove 134. This ensures that the auxiliary gear 137 on the outside of the fixed shaft 136 can tightly mesh with the tooth groove 1311 of the transmission belt 1310, preventing power transmission interruption or slippage between the transmission belt 1310 and the roll-out gear 139 due to the position change caused by the roll-out roller 6 driving the roll-out gear 139. This ensures a continuous and stable discharge process. Its function is to provide stable power to the roll-out roller 6, ensuring the smooth transmission of the document bag 2 to the conveying system 1.To avoid transmission interruptions due to unstable power and maintain the continuity of the sorting process.

[0049] The expansion component 14 includes two support plates 141 mounted on the workbench 4, located on either side of the discharge port 104. Of the two roll-out rollers 6, the upper roll-out roller 6 has its two ends rotatably mounted within the two support plates 141. Each support plate 141 has an expansion groove 142, and an expansion plate 143 is slidably mounted within each of the two expansion grooves 142. An expansion spring 144 is mounted at the bottom of each of the two expansion plates 143, with the bottom ends of the two expansion springs 144 positioned at the bottom of the corresponding expansion groove 142. Of the two roll-out rollers 6, the lower roll-out roller 6 has its two ends rotatably mounted within the two expansion plates 143 and slidably mounted within the two support plates 141. If the document bag 2 to be sorted is thicker, the upper roll-out roller... Roller 6 continues to rotate, while the lower roll-out roller 6, after being squeezed by the document bag 2, will cause its two ends of the expansion plates 143 to slide downward into the corresponding expansion grooves 142. As the expansion plates 143 slide, the expansion spring 144 is compressed and stores energy, allowing the lower roll-out roller 6 to elastically yield downward to accommodate the passage of thicker bags. After the document bag 2 has completely passed through, the expansion spring 144 releases its stored energy, pushing the expansion plates 143 to rise back, so that the lower roll-out roller 6 returns to its original position, ensuring stable clamping and transmission of subsequent document bags 2 of conventional thickness. The spacing is automatically adjusted by the expansion spring 144 without manual intervention, has a wide range of adaptability, and can handle document bags 2 of different thicknesses, avoiding frequent manual adjustments and greatly improving the applicability to document bags 2 of different thicknesses.

[0050] The limiting component 15 includes a limiting plate 151 slidably disposed within the feeding hopper 101, and the limiting plate 151 is located within the discharge port 104. The side of the limiting plate 151 facing the document bag 2 is curved. Connecting rods 152 are provided at both ends of the limiting plate 151, and both connecting rods 152 are slidably disposed within the feeding hopper 101. A horizontal plate 153 is provided at the top of the two connecting rods 152. A limiting screw 154 is rotatably disposed at the top of the feeding hopper 101, and the horizontal plate 153 is threadedly connected to the limiting screw 154. A limiting handle 155 is provided at the top of the limiting screw 154. When the document bag 2 reaches the top of the feeding hopper 102, the position of the limiting plate 151 needs to be adjusted according to the thickness of the document bag 2. At this time, rotating the limiting handle 155 drives the limiting screw 154 to rotate. When rotating, the horizontal plate 153 connected to it by threads moves up or down, thereby driving the connecting rod 152 and the limiting plate 151 to move synchronously until the distance from the top of the limiting plate 151 to the top of the discharge port 104 is slightly greater than the thickness of the document bag 2. This ensures that only a single document bag 2 can pass through at a time, and effectively prevents multiple document bags 2 from sliding out at the same time, causing jamming or overlapping. The arc design of the limiting plate 151 can avoid scratching the document bag 2 and guide the document bag 2 to slide smoothly into the discharge port 104, ensuring a smooth and stable feeding process. The spacing is adjustable to accommodate document bags 2 of different thicknesses, ensuring one-by-one output and avoiding multiple bags from stacking. Its function is to control the number of document bags 2 output, prevent multiple bags from entering the roll-out stage at the same time, causing congestion or sorting errors, and ensure transmission order and sorting accuracy.

[0051] In use, when staff need to sort the document bags 2, they place their foot on the pedal 108 and then press down. The pedal 108 then moves the feeding rods 106 at both ends downwards, causing them to slide within the feeding bin 101. As the feeding rods 106 slide downwards, the feeding plate 105 at the top of the feeding rods 106 slides downwards and into the feeding trough 102. During this process, the feeding spring 107 is compressed and stored until it can no longer be compressed, and the inlet 103 is connected to the feeding trough 102. At this point, the stacked document bags 2 can be placed on the feeding plate 105. Releasing the pedal 108 causes the feeding spring 107 to rebound, pushing... The feeding plate 105 moves upward, causing the document bag 2 to move upward until the uppermost document bag 2 touches the top of the feeding trough 102. It should be noted that the inner wall of the feeding hopper 101 is coated with an anti-friction coating to reduce the resistance between the document bag 2 and the inner wall, ensuring smooth feeding and discharging and preventing scratches on the document bag 2. Once the document bag 2 reaches the top of the feeding trough 102, the position of the limiting plate 151 needs to be adjusted according to the thickness of the document bag 2. At this time, rotating the limiting handle 155 rotates the limiting screw 154. When the limiting screw 154 rotates, the horizontal plate 153 threadedly connected to it moves upward or downward, thereby driving the connecting rod 152 and the limiting plate 151 to move synchronously until the limiting plate... The distance from the top of the limiting plate 151 to the top of the discharge port 104 is slightly greater than the thickness of the document bag 2, ensuring that only one document bag 2 can pass through at a time, and effectively preventing multiple document bags 2 from sliding out simultaneously, causing jamming or overlapping. The arc design of the limiting plate 151 can avoid scratching the document bag 2 and guide the document bag 2 to slide smoothly into the discharge port 104, ensuring a smooth and stable feeding process. The spacing is adjustable to accommodate document bags 2 of different thicknesses, ensuring one-by-one output and avoiding multiple bags stacking. After adjusting the position of the limiting plate 151, the angle of the two push rollers 5 also needs to be adjusted. When the angle of the push rollers 5 needs to be adjusted, turn the adjusting handle 126, so that the adjusting handle 126 drives the adjusting screw 125 to rotate. When the adjusting screw 125 rotates, it drives the adjusting screw 125 to rotate. The threaded synchronous plate 127 moves up and down under the limiting action of the two synchronous rods 124. When the synchronous plate 127 moves up and down, it drives the two synchronous rods 124 to move up and down synchronously through the synchronous groove 128. This causes the adjusting discs 123, which are respectively set at one end of the two synchronous rods 124, to rotate. Under the action of the two adjusting shafts 122, the two adjusting discs 123 rotate around their corresponding adjusting shafts 122, thereby driving the two adjusting shafts 122 to rotate synchronously in opposite directions. When the two adjusting shafts 122 rotate synchronously in opposite directions, they drive the corresponding adjusting rings 121 at one end to rotate together. This causes the angles of the two pushing rollers 5 to change through the two adjusting rings 121.Once the outer sides of the two push rollers 5 contact the two sides of the uppermost document bag 2 and apply appropriate pressure, the rotation of the adjusting handle 126 can be stopped. The rubber material of the two push rollers 5 increases the friction with the document bag 2, and the groove 9 further enhances the gripping force, ensuring that the document bag 2 does not slip or deviate when the push rollers 5 push the document bag 2 and the roll-up roller 6 transmits the document bag 2, providing a stable contact basis for power transmission;

[0052] After adjusting the angles of the two push rollers 5, the drive motor 111 can be started. The drive motor 111 will drive the drive gear 112 at its output end to rotate. During the rotation of the drive gear 112, the drive gear 112 will drive the transmission gear 118 meshing with it to rotate together. When the transmission gear 118 rotates, the drive rod 116 located at the axis of the transmission gear 118 will rotate together with the transmission gear 118. This causes the drive rod 116 to drive the first insert rod 114 to rotate through the drive groove 117 at its axis. When the first insert rod 114 rotates, the second insert rod 115 slidably located in the first insert rod 114 will rotate together with it. This causes the universal joints 11 located at the opposite ends of the first insert rod 114 and the second insert rod 115 to rotate. 3. During rotation, the two universal joints 113 transmit power to the corresponding push rollers 5, causing them to rotate within their respective adjusting rings 121. This smoothly pushes the uppermost document bag 2 to the discharge port 104. During this process, the two push rollers 5 continuously apply uniform pressure to ensure the document bag 2 remains centered and unbiased. The first insert rod 114 and the second insert rod 115 can freely extend and retract to adapt to changes in the deflection angle of the adjusting ring 121 as the adjusting disc 123 drives the adjusting shaft 122 to rotate, ensuring effective power transmission while maintaining stable drive of the push rollers 5 under different inclination states. Once the document bag 2 reaches the discharge port 104 under the action of the two push rollers 5, the document bag... The document bag 2 will be discharged through the area between the top of the adjusted limiting plate 151 and the top of the discharge port 104, and squeezed into one side of the two roll-out rollers 6. At this time, the drive motor 111 is stopped and the power motor 131 is started. After the power motor 131 starts, it will drive the power gear 132 at its output end to rotate. The power gear 132 will drive the transmission belt 1310 to start running through multiple tooth grooves 1311. When the transmission belt 1310 moves under the action of the power gear 132, it will drive the auxiliary gear 137 and the roll-out gear 139 that mesh with it to rotate together, so that the roll-out gear 139 drives the roll-out roller 6 at its shaft to rotate synchronously. As the roll-out roller 6 rotates, the document bag 2 is smoothly wound in and quickly discharged. After exiting the equipment and completing the unloading action, if the document bag 2 to be sorted is thicker, the upper roll-out roller 6 continues to rotate, while the lower roll-out roller 6, after being squeezed by the document bag 2, will cause its two ends of the expansion plates 143 to slide downward into the corresponding expansion grooves 142. As the expansion plates 143 slide, the expansion spring 144 is compressed and stores energy, allowing the lower roll-out roller 6 to elastically yield downward to accommodate the thicker bag. After the document bag 2 has completely passed, the expansion spring 144 releases its stored energy, pushing the expansion plates 143 to rise and returning the lower roll-out roller 6 to its original position, ensuring stable clamping and transmission of subsequent document bags 2 of normal thickness. During this process, the auxiliary gear 137 always remains in an upward pressing state.This ensures that the sliding plate 135 is always in the upwardly pressed limit position within the sliding groove 134, thereby ensuring that the auxiliary gear 137 on the outside of the fixed shaft 136 can tightly mesh with the tooth groove 1311 of the transmission belt 1310. This prevents power transmission interruption or slippage between the transmission belt 1310 and the winding gear 139 due to position changes caused by the winding roller 6 driving the winding gear 139, thus ensuring a continuous and stable discharge process.

[0053] As the roll-out roller 6 continues to rotate, the document bag 2 is quickly and smoothly pulled above the conveyor system 1. The conveyor system 1 then starts and smoothly moves the document bag 2 along the preset track to the bottom of the scanning system 3, thus completing the sorting work. Through modular component design, the feeding, pushing, and roll-out processes are broken down into independent sub-components. Each component not only solves a single problem, but also forms a collaborative closed loop through the circulation of the document bag 2. Ultimately, the core goals of automated replenishment, accurate pushing, adaptation to multiple specifications, and stable conveying are achieved, which greatly reduces manual intervention and improves sorting efficiency and accuracy. This is in line with the development trend of modern logistics sorting equipment that is efficient, intelligent, and flexible.
