Description

Technical Field

[0001] This invention relates to the field of logistics transportation technology, specifically a swing wheel type express sorting device. Background Technology

[0002] The swing wheel type express sorting equipment, also known as the swing wheel sorter or the inclined guide wheel type or deflection wheel type sorter, is a highly efficient automated logistics sorting equipment. It uses a series of tiltable trays (called swing wheels), and drives the sorted items to turn by changing the direction of the contact surface rollers, so as to achieve the sorting purpose. The working principle of the swing wheel sorter is based on the high-precision motion of the swing wheel and the real-time monitoring and adjustment of the intelligent control system. The swing wheel is a precision rotating device that rotates continuously under the drive of an electric motor and is finely adjusted according to the instructions of the intelligent control system to ensure that each item falls accurately into the corresponding collection box. In the operation of a pendulum-type express sorting equipment, express packages first pass through a vision inspection mechanism under the action of a conveyor mechanism. The scanning mechanism identifies the barcodes on the packages, allowing the pendulum machine to perform corresponding sorting work based on the package information. However, in actual sorting, most pendulum-type express sorting equipment sorts packages based on their destination location. Consequently, packages within the same destination area may have varying weights. As we know from express parcel operations, the size, shape, and weight of the items inside the package directly affect the thickness of the package. For example, heavier items usually require thicker packaging materials to ensure safety and stability during transportation, while lighter packages are not thickened accordingly (except for special items such as fragile or valuable items). As a result, during the sorting process, heavier packages often squeeze lighter packages, which can easily lead to damage. Summary of the Invention

[0009] Preferably, the limiting groove includes a sliding area, an inclined upward area connected to the sliding area, and a rising area connected to the inclined upward area. An electromagnetic plate frame is also fixedly installed on the limiting plate frame, and the electromagnetic plate frame is located directly above the rising area.

[0010] Preferably, the movable plate frame is also symmetrically fixedly installed with partitions inside, and a cylinder is fixedly installed on the top of the movable plate frame.

A spring mechanism is connected between the guide seats and one of the connecting seats. An air suction pipe is fixedly installed on the side wall of one of the limiting plate frames. The air suction pipe is used to adsorb dust on the surface of the conveying mechanism.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This swing wheel type express sorting device uses a weighing element to weigh and detect the express packages on the swing wheel mechanism. Under the limiting action of the guide panel, the express packages move to the support panel. The servo motor drives the lead screw to rotate, thereby driving the slider and the action rod to sort and transport the express packages on the support panel according to their weight. At the same time, the buffer panel and torsion spring buffer the downward sliding force of the express packages, thereby reducing the force of the express packages moving. In addition, the express packages are sorted according to their weight, which can effectively prevent heavier express packages from squeezing lighter express packages.

[0015] 2. This swing wheel type express sorting device can flexibly adjust the space inside the storage box by using a telescopic plate frame to ensure that the storage box space is fully utilized. At the same time, under the action of the buffer spring, it can effectively prevent heavier express packages from pushing the telescopic plate frame towards the accumulation area of ​​lighter express packages after a certain number have accumulated, thereby preventing lighter express packages from being squeezed.

[0016] 3. This swing wheel type express sorting device utilizes the movement relationship between the telescopic rod frame and the distance control plate to make the moving plate frame move at the upper limit of the limit plate frame. The position of the express packages is adjusted by the cylinder and vacuum suction cup. At the same time, the transmission shaft uses the meshing relationship of the transmission gear and the meshing toothed rack to make the flexible cleaning roller adjust its position along with the fixed base on the belt drive mechanism. This can effectively clean the bottom of the express package. Under the action of the drive gear and the drive toothed rack, the flexible cleaning roller rotates to clean the bottom of the express package. The dust adhering to the flexible cleaning roller is then removed by the action of the arc-shaped cleaning scraper. This can effectively deal with the dust on the bottom of the express package and prevent the dust from affecting the weighing elements and other sensors on the swing wheel mechanism.

[0017] 4. This swing wheel type express sorting device uses an air suction pipe to adsorb dust on the surface of the conveyor mechanism, thereby effectively treating the dust on the express delivery and conveyor mechanism surfaces. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-13This invention discloses a swing wheel type express sorting device. Addressing the technical problems in the prior art, the device includes multiple conveying mechanisms 1, a scanning mechanism 2 for identifying express information, and a swing wheel mechanism 3 between each pair of adjacent conveying mechanisms 1. A weighing element 31 for detecting the weight of the express is fixedly installed on the swing wheel mechanism 3. Expresses are conveyed through the conveying mechanisms 1 to the scanning mechanism 2, where the scanning mechanism 2 scans the barcode on the express. The express is then conveyed through the conveying mechanisms 1 to the swing wheel mechanism 3, where the weighing element 31 detects the weight. A lifting mechanism 4 is located on one side of the swing wheel mechanism 3, with a storage box 41 on its surface for collecting the sorted expresses. The lifting mechanism 4 is a prior art component used for lifting, and therefore not described in detail in this invention. A flow guide chamber 5 is also located on one side of the swing wheel mechanism 3, with a flow guide plate frame 51 fixedly installed inside. The storage box 41 is located within the flow guide chamber 5. Figure 2 It is known that the flow guide chamber 5 contains an inlet and an outlet, and the storage box 41 is located inside the outlet of the flow guide chamber 5. A guide panel 52 is symmetrically fixedly installed on the flow guide frame 51, and a support panel 53 is also fixedly installed on the flow guide frame 51, so that the express delivery enters the flow guide chamber 5 under the action of the swing wheel mechanism 3, passes through the flow guide frame 51, and enters the support panel 53. Further, rubber buffer pads are fixedly installed on both the guide panel 52 and the support panel 53. A servo motor 54 is fixedly installed on one side of the flow guide chamber 5, and the output end of the servo motor 54 penetrates through the side wall of the flow guide chamber 5 and extends into its interior. A lead screw 55 is fixedly installed on the output end of the servo motor 54, and the end of the lead screw 55 is rotatably connected to the inner wall of the flow guide chamber 5. A drive slider 56 is installed on the lead screw 55. A guide shaft 57 is fixedly connected between the inner walls of both sides of the flow guide chamber 5, and the drive slider 56 is positioned above the upper limit of the guide shaft 57. The sliding mechanism has symmetrically mounted action rods 561 at the bottom of the drive slider 56, and the express delivery on the support panel 53 is located between the action rods 561. Buffer panels 58 are symmetrically arranged inside the guide plate frame 51, and each buffer panel 58 is fixedly mounted with a drive shaft 581 rotatably connected to the guide plate frame 51. The end of the drive shaft 581 passes through the guide plate frame 51 and the inner wall of the guide chamber 5, and extends to the outside of the guide chamber 5. A torsion spring 582 connects the drive shaft 581 to the outer wall of the guide chamber 5. Multiple fixed shafts 59 are also fixedly installed between the inner walls on both sides of the guide chamber 5. A telescopic plate frame 591 is also provided inside the guide chamber 5, and the telescopic plate frame 591 slides at the upper limit of the multiple fixed shafts 59. A buffer spring 592 connects each fixed shaft 59 to the telescopic plate frame 591. The centerline of the telescopic plate frame 591 coincides with the centerline of the guide chamber 5, thus facilitating the buffering effect on the movement force of the express delivery.

[0022] Following the above, in conjunction with the appendix Figure 2 Appendix Figure 4 -Appendix Figure 7As shown, the weighing element 31 weighs the express package on the balance wheel mechanism 3. After obtaining the weight, the balance wheel mechanism 3 pushes the express package into the flow guide chamber 5, that is, the express package enters the flow guide plate frame 51. Under the limiting action of the guide panel 52, the express package moves to the support panel 53. It should be noted that the support panel 53 is located at the center of the flow guide chamber 5, and the support panel 53 is U-shaped. One side of the support panel 53 forms a channel A 9 with the inner wall of the flow guide chamber 5, and the other side of the support panel 53 forms a channel B 10 with the inner wall of the flow guide chamber 5 (for ease of description, A will be used below). Channels A (A) and B (B) (distinguishing between two channels) are used. Channel A (A) is for lighter express deliveries, while channel B (B) is for heavier express deliveries. This weight determination can be adjusted by data control of the machinery before sorting. At this time, the servo motor 54 rotates forward or backward based on the detected express weight. Assuming the express is heavier, the servo motor 54 rotates forward, and the lead screw 55 rotates with the output of the servo motor 54. The drive slider 56 on the lead screw 55 moves forward under the action of the guide shaft 57. Simultaneously, the drive slider 56... One of the levers 561 acts on the express delivery on the support panel 53. The express delivery, under this force, enters the B channel 10 and moves along the trajectory of the B channel 10 until it reaches the buffer panel 58. The buffer panel 58 rotates under the force of the express delivery, i.e., the drive shaft 581 rotates. At this time, the torsion spring 582 deforms, and the buffer panel 58 adjusts its angle under the action of the drive shaft 581. The express delivery then falls into the storage box 41. As the express delivery falls into the storage box 41, under the action of the buffer panel 58, this… The downward force is buffered, so the force of falling into the storage box 41 is smaller. It should be noted that the lifting mechanism 4 can adjust the position of the storage box 41 to ensure that the bottom of the storage box 41 is close to the buffer panel 58, thereby effectively reducing the downward force of the express. Correspondingly, if a lighter express is being transported, the servo motor 54 drives the lead screw 55 to reverse, and then the drive slider 56 on the lead screw 55 moves in the opposite direction under the action of the guide shaft 57. Repeat the above operation, and the express enters the A channel 9 and falls into the storage box 41.When the number of packages inside the storage box 41 reaches a certain level, the remaining space on both sides of the telescopic shelf 591 will inevitably differ. To maximize the space utilization of the storage box 41, this invention employs the following design: packages on the side of the telescopic shelf 591 with less remaining space will exert a force on the telescopic shelf 591, causing it to move towards the side with more remaining space, thereby improving space utilization. It should be noted that this operation is suitable for situations where the remaining space on both sides of the telescopic shelf 591 differs significantly, and the main function of the telescopic shelf 591 is to flexibly adjust the space within the storage box 41. When the remaining space on both sides of the telescopic shelf 591 is not significantly different, the telescopic shelf 591 generally will not move, and the buffer spring 592 will impede its movement. This buffer spring 592 effectively prevents heavier packages from pushing the telescopic shelf 591 towards the area where lighter packages accumulate after a certain number have accumulated.

[0023] Furthermore, the present invention uses the guide plate frame 51 and the guide panel 52 and support panel 53 thereon to move the movement trajectory of the express delivery. Under the action of the servo motor 54, the lead screw 55 drives the drive slider 56 and the action rod frame 561 thereon to apply force to the express delivery, so as to achieve the purpose of screening according to weight. This can effectively avoid the situation where heavier express delivery will squeeze lighter express delivery. At the same time, under the action of the lifting mechanism 4, the bottom of the storage box 41 is close to the buffer panel 58, which can effectively reduce the downward force of the express delivery. And by using the angle change of the buffer panel 58, the force of the express delivery moving downward is buffered.

[0024] As mentioned above, during the sorting process, some packages inevitably accumulate a lot of dust on their bottoms (partly due to the fact that packages frequently come into contact with complex external environments during handling, inevitably accumulating dust). When these dusty packages move to the balance wheel mechanism 3, they can obstruct the sensor surface (including the weighing element 31). Dust particles may cover the sensitive surface of the sensor, causing the signal received by the sensor to weaken or become distorted. Furthermore, long-term dust accumulation may cause wear and tear on the mechanical structure of the sensor, shortening its lifespan. Therefore, to avoid dust affecting the weighing element 31 and other sensors... The present invention incorporates the following design: Limiting plates 6 are fixedly installed on both sides of the conveying mechanism 1 where the scanning mechanism 2 is mounted, and a movable plate 61 is provided between the limiting plates 6. The movable plate 61 slides at both ends of the limiting plates 6. Multiple distance control plates 11 are also fixedly installed on the conveying mechanism 1 where the scanning mechanism 2 is mounted. These distance control plates 11 ensure a certain distance between each pair of adjacent express packages, thereby effectively controlling the express delivery speed and preventing the balance wheel mechanism 3 from operating at high speed for extended periods. When the express sorting volume is too large, the numerous sorting tasks will cause the key components of the balance wheel mechanism 3, such as the balance wheel and transmission device, to experience more frequent friction and wear. Picking tasks require the balance wheel mechanism 3 to operate at a continuous high speed, which may lead to excessive heat generation inside the machine. If the cooling system cannot effectively dissipate the heat, the machine may overheat, affecting its performance and potentially damaging internal circuits and components. Therefore, the distance control plate 11 effectively prevents adjacent express packages from being too close, avoiding continuous high-speed operation of the balance wheel mechanism 3. A telescopic rod frame 62 is symmetrically fixed on the moving plate frame 61, with the end of the telescopic rod frame 62 located on the movement trajectory of the distance control plate 11. Thus, when one of the distance control plates 11 moves to the end of the telescopic rod frame 62, the distance control plate 11 will... The telescopic rod 62 drives the movable plate 61 to move in a directional manner on the limiting plate 6. Guide seats 7 are fixedly installed on both sides of the movable plate 61. A connecting seat 60 is installed parallel to the side wall of each limiting plate 6, and a limiting shaft 601 is fixedly installed between the connecting seats 60. The guide seat 7 slides at the upper limit of the limiting shaft 601. A spring mechanism 602 is connected between the guide seat 7 and one of the connecting seats 60. An air suction pipe 8 is fixedly installed on the side wall of one of the limiting plate 6, and the air suction pipe 8 is used to adsorb dust on the surface of the conveying mechanism 1, thereby effectively treating the dust on the surface of the express delivery and the conveying mechanism 1.

[0025] A sliding shaft 621 is fixedly installed on one side of the output end of the telescopic rod 62. A limiting groove 63 is provided on the side wall of the limiting plate frame 6, and the end of the sliding shaft 621 passes through the limiting groove 63 and extends to the outside of the limiting plate frame 6. The sliding shaft 621 slides in the limiting groove 63. An annular magnetic plate 622 is fixedly installed at the end of the sliding shaft 621 located outside the limiting plate frame 6. As a further limitation of the present invention, the limiting groove 63 includes a sliding area 631, an inclined upward area 632 communicating with the sliding area 631, and a rising area 633 communicating with the inclined upward area 632. In the initial state, that is, when the distance control plate 11 does not act on the end of the telescopic rod 62, the sliding shaft 621 is located in the sliding area 631. At the initial end (i.e., the end away from the inclined upward region 632), an electromagnetic plate frame 64 is also fixedly installed on the limiting plate frame 6, and the electromagnetic plate frame 64 is located directly above the rising region 633. The electromagnetic plate frame 64 is located on the movement trajectory of the annular magnetic plate 622, and when the electromagnetic plate frame 64 is energized, it generates an attractive force on the annular magnetic plate 622 located directly below it. A partition plate 65 is also symmetrically fixedly installed inside the movable plate frame 61. A cylinder 611 is fixedly installed on the top of the movable plate frame 61, and the output end of the cylinder 611 passes through the top of the movable plate frame 61 and extends into its interior. A vacuum suction cup 612 for suction of express delivery is fixedly installed on the output end of the cylinder 611. A drive shaft 66 is symmetrically installed on each partition plate 65, and the end of the drive shaft 66... All components penetrate the sidewall of partition 65 and are rotatably connected to it. The drive shafts 66 are connected by a belt drive mechanism 67. Further, cylinder 611 drives vacuum suction cup 612 to descend via its output end. When the surface of vacuum suction cup 612 contacts the surface of the express delivery, it adsorbs the express delivery surface. Subsequently, cylinder 611 drives vacuum suction cup 612 back to its initial position. A drive gear 661 is fixedly installed at the end of one of the drive shafts 66, and a meshing gear rack 68 is fixedly installed on the sidewall of the limiting plate frame 6. The drive gear 661 and the meshing gear rack 68 are in a meshing state. A fixed seat 671 is also fixedly installed on the belt drive mechanism 67, and the fixed seats 671 are rotatably connected to each other for controlling the express delivery. A flexible cleaning roller 672 is used for bottom cleaning. Both ends of the flexible cleaning roller 672 are fixedly installed with drive gears 673, and a drive gear row 69 that is meshed with the drive gears 673 is fixedly installed on one side of the partition plate 65. An arc-shaped cleaning scraper 674 is also fixedly connected between the fixed bases 671, and the flexible cleaning roller 672 is located inside the arc-shaped cleaning scraper 674. Furthermore, the flexible cleaning roller 672 is preferably made of a deformable wiping material such as a sponge. When the cylinder 611 drives the vacuum suction cup 612 back to the initial position, the flexible cleaning roller 672 is located below the express delivery, so that the bottom of the express delivery can be cleaned, thereby avoiding the dust from affecting the weighing element 31 and other sensors on the swing wheel mechanism 3.

[0026] Following the above, in conjunction with the appendix Figure 8 -Appendix Figure 13As shown, when the control plate 11 moves to the end of the telescopic rod 62, the control plate 11 applies a force to the end of the telescopic rod 62, causing the telescopic rod 62 to drive the movable plate 61 to move in a directional manner on the limiting plate 6. At this time, the sliding shaft 621 on the telescopic rod 62 moves along the sliding area 631 of the limiting groove 63. During the movement, the guide seats 7 on both sides of the movable plate 61 move at the upper limit of the limiting shaft 601, and the connecting seat 60 stretches the spring mechanism 602. During the movement of the movable plate 61, the cylinder 611 is activated, and its output end drives the vacuum suction cup 612 to pick up the express below. After picking up the express, the cylinder 611 drives the vacuum suction cup 612 back to the initial position, that is, the express is lifted. During the lifting motion, with the flexible cleaning roller 672 positioned below the express delivery, the transmission gear 661 at the end of one of the transmission shafts 66 interacts with the meshing gear row 68 on the side wall of the limiting frame 6. The transmission gear 661 is subjected to the meshing force of the meshing gear row 68, causing the transmission shaft 66 to rotate, thus rotating the belt drive mechanism 67. The fixed seat 671 on the belt drive mechanism 67 moves in a directional manner under the action of the belt drive mechanism 67. Consequently, the arc-shaped cleaning scraper 674 on the fixed seat 671 and the flexible cleaning roller 672, rotatably connected to the fixed seat 671, move synchronously with the fixed seat 671. The flexible cleaning roller 672 moves towards the bottom of the express delivery. During the movement of 72, the drive gear 673 at its end is rotated by the drive gear rack 69 (fixed on the side wall of the partition 65), that is, the drive gear 673 drives the flexible cleaning roller 672 to rotate and clean the bottom of the express delivery. The dust adhering to the flexible cleaning roller 672 is cleaned by the arc-shaped cleaning scraper 674, and the suction pipe 8 will adsorb the dust on the surface of the conveying mechanism 1. During the movement of the sliding shaft 621 in the sliding area 631, the dust at the bottom of the express delivery is cleaned by the flexible cleaning roller 672. When the sliding shaft 621 moves to near the end of the sliding area 631, the cylinder 611 causes the vacuum suction cup 612 to drive the express delivery down to the surface of the conveying mechanism 1 through the output end. Then the sliding shaft 621 moves to the end of the sliding area 631. The sliding shaft 621 moves upward along the inclined upward region 632. When the sliding shaft 621 reaches the end of the inclined upward region 632, the end of the telescopic rod 62 is no longer on the movement trajectory of the control plate 11, and is therefore no longer subject to the force of the control plate 11. At the same time, the electromagnetic plate 64 is energized, generating an attractive force on the annular magnetic plate 622 directly below it. The sliding shaft 621 moves to the end of the rising region 633. At this point, the end of the telescopic rod 62 is no longer on the movement trajectory of the control plate 11, nor on the movement trajectory of the express delivery, thus avoiding any impact on the movement of the express delivery. The electromagnetic plate 64 is energized for 2 seconds (the specific time can be set according to the actual sorting process) and then automatically de-energized. At this time, the express delivery has left from under the moving plate 61.Subsequently, the movable plate frame 61 returns to its initial position under the action of the spring mechanism 602. That is, the sliding shaft 621 moves from the end of the rising region 633 to the end of the inclined upward region 632 under the action of gravity, enters the sliding region 631 along the trajectory of the inclined upward region 632, and finally returns to the initial end of the sliding region 631. Thus, through the structural design of this invention, dust on the bottom of the express delivery can be effectively treated, preventing dust from affecting the weighing element 31 and other sensors on the balance wheel mechanism 3.
