Description

Technical Field

[0001] This invention relates to the field of sorting equipment technology, specifically a sorting and transportation equipment for warehouse logistics. Background Technology

[0002] In warehouse logistics operations, in order to reduce labor costs and the labor intensity of workers, existing technologies usually replace manual labor by setting up sorting and transportation equipment to complete the sorting of logistics express deliveries.

[0003] Existing sorting and transportation equipment typically uses electric conveyor rollers or belt conveyors to transport logistics packages. By setting up a pushing structure, the logistics packages are pushed after they move to the corresponding slide, so that they can easily flow through slides at different positions to complete the sorting operation. However, this sorting method is relatively reliable for handling small and medium-sized express packages due to their light weight and the use of chute conveyors. But when dealing with larger and heavier express packages, the chute conveyor is prone to tipping over due to its greater inertia as it rushes out of the chute, causing unnecessary damage to the contents. This is especially true when the packaging contains fragile items, which increases the risk of damage and reduces the operational stability of the sorting equipment. Therefore, a sorting and transportation equipment for warehouse logistics is proposed to address the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this invention to solve its technical problem is: a sorting and transportation equipment for warehouse logistics, comprising: A support frame, with multiple first electric conveyor rollers rotatably mounted inside the support frame, is used to convey express along a first direction; A measuring light curtain is fixedly installed inside the support frame to detect the length of the passing express delivery in order to determine its size. Multiple pushing units are arranged sequentially on the outside of the support frame along the conveying direction. Each pushing unit includes a push plate, a sensing unit mounted on the push plate, and a power source that drives the push plate to move laterally. Two sets of slides are fixed to one side of the support frame and correspond to different pushing units respectively; The transfer assembly, installed on one side of the support frame, is used to receive large-volume express packages being pushed and transfer them to the downstream conveyor line while keeping the load-bearing surface facing upwards. The receiving and conveying assembly includes a fixed frame, a second electric conveyor roller mounted inside the fixed frame, and a belt conveyor, for receiving and conveying express packages transferred downstream via the transfer assembly.

[0006] Preferably, a guide plate is fixedly connected to one side opening of the slide, and an elastic pad is fixedly connected to one side of the guide plate.

[0007] Preferably, the uppermost vertex of the second electric conveyor roller in the receiving and conveying assembly is higher than the plane of the loading frame used to place the express delivery, and both the second electric conveyor roller and the belt conveyor are used in conjunction with the loading frame that has moved to the lowest position. When the loading frame moves to the lowest position, the groove in the middle section of the loading frame accommodates the second electric conveyor roller, and at the same time, the bottom surface of the express delivery on the loading frame contacts the second electric conveyor roller. The rotation of the second electric conveyor roller drives the express delivery to move onto the belt conveyor, thereby separating the express delivery from the loading frame.

[0008] Preferably, the pushing unit includes: a servo cylinder, which is fixedly connected to the outside of the support frame, and its output end is fixedly connected to the push plate; a photoelectric sensor, which is a reflective type, with its transmitting end and receiving end integrated in the same housing, and installed on the end of the push plate facing the direction of the express delivery; the servo cylinders include multiple ones arranged sequentially along the conveying direction, of which only one servo cylinder corresponds to the transfer component, and a position detection sensor is fixedly installed on the housing of the servo cylinder, with the detection end of the position detection sensor aligned with the push plate driven by the servo cylinder, for detecting the return status of the push plate; the other servo cylinders are not equipped with position detection sensors.

[0009] Preferably, a stop bar is fixedly connected to the inner side of the support frame, and the push plate on the far right is used in conjunction with the stop bar.

[0010] Preferably, the transfer assembly includes: two support plates fixedly connected to one side of the support frame; two rotating frames rotatably mounted on the inner sides of the two support plates, and the two rotating frames rotate in fixed positions on the inner sides of the support plates, with the rotation centers of the two rotating frames staggered; multiple loading frames rotatably mounted on corresponding ends of the two rotating frames, and the loading frames are fixedly positioned at the ends of the rotating frames, with a slot in the middle section of the loading frame; the power source for driving the rotation of one rotating frame is a servo motor, fixedly connected to one side of the support frame, with its output end fixedly connected to one rotating frame.

[0011] Preferably, two rotating frames are fixedly connected to the outer sides with rings, and the support frame is fixedly connected to the outer side with a limiting ring, wherein the rings and the limiting ring are rotatably connected.

[0012] Preferably, connecting plates are fixedly connected to multiple ends of the two outer sides of the rotating frame, and reinforcing strips are provided on the outer side of the connecting plates, which are used in conjunction with the connecting plates.

[0013] The advantages of this invention are: 1. The sorting and transportation equipment for warehouse logistics described in this invention determines the volume of express packages by measuring light curtains and selects different sorting paths according to the size of the packages. Small and medium-sized packages are directly pushed into two different chutes for diversion, while large packages are smoothly transferred to the downstream conveyor line via transfer components. This avoids heavy objects from tipping over and being damaged due to their large inertia on the chutes, thereby improving the stability of sorting and the ability to protect fragile items.

[0014] 2. The sorting and transportation equipment for warehouse logistics described in this invention, when in use, further guides and obstructs small and medium-sized express packages through the guide plate, so that their sliding on the inner side of the slide can be relatively smoother, further cushioning their packaging and inner items, thereby improving the buffering performance of the device.

Detailed Implementation

[0018] 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.

[0019] Specific implementation examples are given below.

[0020] Please see Figures 1 to 10 As shown in the embodiment of the present invention, a sorting and transportation device for warehouse logistics includes: Support frame 101, multiple first electric conveying rollers 201 are rotatably mounted inside support frame 101 for conveying express along a first direction; The measuring light curtain 301 is fixedly installed inside the support frame 101 and is used to detect the length of the express delivery to determine its size. Multiple pushing units are arranged sequentially on the outside of the support frame 101 along the conveying direction. Each pushing unit includes a push plate 402, a sensing unit mounted on the push plate 402, and a power source that drives the push plate 402 to move laterally. The sensing unit is used to send a trigger signal after the express delivery passes through its detection area and leaves. Two sets of slides 501 are fixed to one side of the support frame 101 and correspond to different pushing units respectively; The transfer component, installed on one side of the support frame 101, is used to receive the large-volume express delivery being pushed and transfer it to the downstream conveyor line while keeping the load-bearing surface facing upward. The receiving and conveying assembly includes a fixed frame 701, a second electric conveying roller 702 installed inside the fixed frame 701, and a belt conveyor 703, for receiving and conveying express packages transferred downstream via the transfer assembly.

[0021] Before implementation, it is worth noting that: when using this device, all electric components and sensors should be connected to the same controller, which uses conventional existing components; the measuring light curtain 301 is a conventional component of existing technology; the sensing unit is installed at the end of the push plate 402 facing the direction of the express delivery, and its output signal is normally shielded by the controller. In use, the express delivery is driven by the first electric conveyor roller 201 to pass through the measuring light curtain 301 and each push unit in sequence; the measuring light curtain 301 detects the length of the express delivery to determine its size, and the controller decides to shield or activate the sensing unit at the corresponding position based on the size; the express delivery continues to move, and when it passes through the detection area of ​​the activated sensing unit and leaves, the sensing unit sends a trigger signal, and the controller starts the corresponding power source, causing the push plate 402 to push the express delivery to the slide 501 or the transfer component; for large express delivery, after being pushed to the transfer component, the transfer component transfers it to the receiving conveyor component with the bearing surface facing upwards, and then it is transported downstream by the second electric conveyor roller 702 and the belt conveyor 703.

[0022] In other words, the volume of the express delivery is determined by measuring the light curtain 301, and different sorting paths are selected according to the size of the volume. Small and medium-sized express delivery is directly pushed into two different slides 501 for diversion, while large express delivery is smoothly transferred to the downstream conveyor line through the transfer component. This avoids heavy objects from tipping over and being damaged due to large inertia on the slide 501, and improves the stability of sorting and the ability to protect fragile items.

[0023] Please see Figure 1 , Figure 2 and Figure 10 As shown, the power source in the pushing unit is a servo cylinder 401, which is fixedly connected to the outside of the support frame 101, and its output end is fixedly connected to the push plate 402. The sensing unit is a photoelectric sensor 403, which is a reflective type. Its transmitting end and receiving end are integrated in the same housing and installed on the end of the push plate 402 facing the direction of the express delivery. The servo cylinders 401 include multiple ones arranged sequentially along the conveying direction. Only one servo cylinder 401 corresponds to the transfer component. A position detection sensor 404 is fixedly installed on the housing of the servo cylinder 401. The detection end of the position detection sensor 404 is aligned with the push plate 402 driven by the servo cylinder 401 to detect the return status of the push plate 402. The other servo cylinders 401 are not equipped with position detection sensors 404.

[0024] Before implementation, it is worth noting that: multiple servo cylinders 401 are arranged sequentially along the conveying direction. The servo cylinder 401 corresponding to the transfer component (the one closest to the transfer component) is equipped with a positioning detection sensor 404, while the other two servo cylinders 401 are not. A photoelectric sensor 403 is installed at the end of the push plate 402 facing the direction of the incoming express delivery, and its irradiation range should be unobstructed. The controller pre-determines which photoelectric sensor 403 to activate (i.e., unshields the signal of that sensor) based on the express delivery volume measured by the measuring light curtain 301, while simultaneously shielding the other photoelectric sensors 403. During the express delivery's movement, it passes each photoelectric sensor 403 sequentially, but only the activated sensor sends a trigger signal to the controller after the express delivery has completely left the irradiation path. Upon receiving the trigger signal, the controller immediately activates the corresponding servo cylinder 401, causing the push plate 402 to extend laterally, pushing the express delivery away from the conveying direction. For the servo cylinder 401 (i.e. the cylinder corresponding to the transfer component) equipped with the position detection sensor 404, when the pusher plate 402 completes pushing and returns to its position near the position detection sensor 404, the sensor sends a return completion signal to the controller. Only after receiving the signal will the controller start the servo motor 604 to drive the transfer component to rotate and transfer the large-volume express to the receiving conveyor component. For the other two servo cylinders 401 (corresponding to the slide 501) that are not equipped with the position detection sensor 404, the controller ends the current sorting action after the pusher plate 402 returns to its position, without issuing any additional signals.

[0025] In other words, the logic of "triggered after the express delivery leaves" is adopted to ensure accurate timing of the pushing action; the photoelectric sensor 403 is selectively activated by the controller to achieve differentiated sorting of express delivery with different volumes; a position detection sensor 404 is set only on the servo cylinder 401 of the corresponding transfer component. This sensor uses the push plate 402 itself as the detection object. After the push plate 402 returns to its position, it sends a signal to ensure that the transfer component is started only after the large-volume express delivery has been pushed and safely returned to its position, thus avoiding timing errors and mechanical interference; at the same time, it does not increase the sensor cost of other cylinders, and the structure is simple and the control is reliable.

[0026] Please see Figures 1 to 7 As shown, the transfer assembly includes: two support plates 601, fixedly connected to one side of the support frame 101; two rotating frames 602, respectively rotatably mounted on the inner side of the two support plates 601, and the two rotating frames 602 rotate in a fixed position on the inner side of the support plates 601, with the rotation centers of the two rotating frames 602 staggered; multiple loading frames 603, respectively rotatably mounted on the corresponding ends of the two rotating frames 602, and the loading frames 603 are fixedly positioned at the ends of the rotating frames 602, with a slot in the middle section of the loading frame 603; the power source for driving the rotation of one rotating frame 602 is a servo motor 604, fixedly connected to one side of the support frame 101, with its output end fixedly connected to one rotating frame 602.

[0027] Before implementation, it is worth noting that: the two rotating frames 602 are identical in shape, both being cross-shaped, with multiple ends evenly distributed along the circumference; each loading frame 603 has its two ends rotatably connected to the corresponding ends of the two rotating frames 602, and the arm lengths of the two rotating frames 602 are equal, meaning the distance from their respective centers to their ends is the same; the distance between the hinge points at both ends of the loading frame 603 is equal to the distance between the centers of the two rotating frames 602; the servo motor 604 drives the two rotating frames 602 to rotate synchronously and in the same direction. This geometric relationship ensures that the loading frame 603 can only perform translational motion during its revolution, meaning that while the loading frame 603 rotates, one side always faces upwards to stably support the express delivery. In use, because the rotation centers of the two rotating frames 602 are offset and the end connection points are at different positions, when the servo motor 604 drives one rotating frame 602 to rotate, both rotating frames 602 rotate synchronously, but under the constraint of these two points, the bearing surface of the loading frame 603 always remains upwards. The slot in the middle of the loading frame 603 is designed to avoid the second electric conveyor roller 702 that receives the conveying assembly when the loading frame 603 moves to the lowest position, thus preventing collision and interference between the two. The servo motor 604 rotates a quarter turn each time, causing the uppermost loading frame 603 to move sequentially to the lowest position.

[0028] In other words, by using two rotating frames 602 with their centers of rotation offset to limit the loading frame 603 at two points, the loading frame 603 achieves the effect that the bearing surface always faces upward during the revolution, ensuring that large-volume express packages remain stable and do not tip over during transfer; the slot opened in the middle section of the loading frame 603 effectively avoids interference with downstream conveying equipment, and the structure is compact and reliable.

[0029] Please see Figure 2 and Figure 5 As shown, the uppermost vertex of the second electric conveyor roller 702 in the receiving and conveying assembly is higher than the plane of the loading frame 603 used to place the express delivery, and both the second electric conveyor roller 702 and the belt conveyor 703 are used in conjunction with the loading frame 603 when it is moved to the lowest position; when the loading frame 603 is moved to the lowest position, the groove in the middle section of the loading frame 603 accommodates the second electric conveyor roller 702, and at the same time, the bottom surface of the express delivery on the loading frame 603 contacts the second electric conveyor roller 702. The second electric conveyor roller 702 rotates and drives the express delivery to the belt conveyor 703, so that the express delivery is separated from the loading frame 603.

[0030] Before implementation, it is worth noting that the position of the fixed frame 701 should ensure that when the loading frame 603 rotates to its lowest position, the groove in the middle section of the loading frame 603 just accommodates the second electric conveyor roller 702, preventing them from contacting each other. Simultaneously, the bottom side of the express delivery on the loading frame 603 should preferentially contact the second electric conveyor roller 702. The second electric conveyor roller 702 and the belt conveyor 703 operate continuously. When the express delivery is placed at its lowest position by the loading frame 603, the bottom of the express delivery contacts and is driven by the second electric conveyor roller 702, thus moving it onto the belt section of the belt conveyor 703 for continued downstream transport. After the express delivery is completely detached from the loading frame 603, the loading frame 603 can then rotate upwards without load.

[0031] In other words, the slot in the middle of the loading frame 603 and the cooperation of the second electric conveyor roller 702 enable interference-free express delivery; the active drive of the second electric conveyor roller 702 allows large express packages to smoothly transition from the loading frame 603 to the belt conveyor 703, avoiding the problem of the packages being unable to slide off on their own due to their weight; at the same time, the separation process between the express package and the loading frame 603 is smooth and impact-free, protecting the fragile items inside.

[0032] Please see Figure 2 and Figure 4 As shown, a baffle 606 is fixedly connected to the inner side of the support frame 101, and the push plate 402 on the far right is used in conjunction with the baffle 606; Before implementation, it is worth noting that: one side of the baffle 606 should be aligned with one side of the loading rack 603 so that when the rightmost push plate 402 pushes the large-volume express, the baffle 606 can further block it, so that the large-volume express can enter the inner side of the loading rack 603 more stably when it is pushed. In other words, when pushing large-volume express packages, the baffle 606 can block and limit them, so that the rightmost servo cylinder 401 can move its output end relatively smoothly without worrying about the large-volume express package moving excessively. This makes it easier for the large-volume express package to enter the loading rack 603 more smoothly, thus improving the stability of the device in sorting large-volume express packages.

[0033] Please see Figures 3 to 5 As shown, two rotating frames 602 are fixedly connected to the outer sides of a ring 607, and a limiting ring 608 is fixedly connected to the outer side of the support frame 101. The ring 607 and the limiting ring 608 are rotatably connected. Before implementation, it is worth noting that: the ring 607 is fitted inside the limiting ring 608 for rotation, and the contact point between the two should be lubricated. The inner wall of the recessed part of the limiting ring 608 should fit against the outer surface of the ring 607. When the rotating frame 602 rotates, the limiting ring 608 limits the ring 607, and the ring 607 then guides and limits the rotating frame 602. That is, when the rotating frame 602 rotates up and down, the limiting ring 608 limits the circular ring 607, so that the circular ring 607 further guides and limits the rotating frame 602, making the rotation trajectory of the rotating frame 602 more stable, which in turn facilitates more stable rotation support of large-volume expresses and improves the stability of the device.

[0034] Please see Figure 5 As shown, multiple ends of the two rotating frames 602 are fixedly connected to connecting plates 609. Reinforcing strips 610 are provided on the outside of the connecting plates 609. The reinforcing strips 610 and the connecting plates 609 are used in conjunction. Before implementation, it is worth noting that when the rotating frame 602 is in use, the workers can align multiple reinforcing strips 610 of different lengths with the connecting plate 609 on the outer end of the rotating frame 602, and screw bolts into the holes on both ends of the reinforcing strip 610 and the connecting plate 609 to complete the connection of the reinforcing strip 610, thereby further connecting the multiple ends of the rotating frame 602. In other words, when in use, by connecting the reinforcing strip 610 to the connecting plate 609 at the end of the rotating frame 602, the integrity of the rotating frame 602 is further enhanced. When transporting the loading frame 603 and heavy express packages, the pressure can be distributed to the other ends, thereby further enhancing the support of the rotating frame 602 and improving the stability of the device.

[0035] Please see Figure 1 and Figure 2 As shown, a guide plate 502 is fixedly connected to one side opening of the slide 501, and an elastic pad 503 is fixedly connected to one side of the guide plate 502; Before implementation, it is worth noting that there are six guide plates 502, divided into two groups. The side of the guide plate facing the support frame 101 is provided with an elastic pad 503. The guide plate 502 is in the shape of an inclined plate, and the elastic pad 503 covers one side of it. When small and medium-sized express packages are pushed into the inside of the slide 501, the guide plate 502 guides them to extend the path required for them to slide down. At the same time, the elastic pad 503 separates the express package from the guide plate 502 so that the two do not collide hard. In other words, during use, the guide plate 502 further guides and blocks small and medium-sized express packages, making their sliding inside the slide 501 relatively smoother, further cushioning their packaging and inner items, and improving the device's cushioning performance.

[0036] Working principle: S1: Express loading and volume detection The package is conveyed by the first electric conveyor roller 201 and passes through the measuring light curtain 301 in sequence. The measuring light curtain 301 detects the length of the package, and the controller determines the size of the package (regular or large) based on the length data, and decides which sensor unit of the subsequent push unit to activate.

[0037] S2: Volume determination and sensor unit pre-selection For standard parts, the controller activates the photoelectric sensor 403 at the entrance of the corresponding slide 501 (while disabling the other photoelectric sensors 403); for large parts, the controller activates the photoelectric sensor 403 at the entrance of the corresponding transfer component.

[0038] S3: Delivery arrival and push notification triggering The package continues to move, and once it has completely passed the illumination path of the activated photoelectric sensor 403, the sensor sends a trigger signal to the controller. The controller immediately activates the corresponding servo cylinder 401, driving the pusher plate 402 to extend laterally and push the package toward the target position (slide 501 or loading rack 603 of the transfer assembly).

[0039] S4: Standard component diversion For regular items, a pusher plate 402, used to push medium or small express packages, pushes them into the corresponding slide rail 501. The packages slide down the slide rail 501 to complete the sorting process. The pusher plate 402 then automatically returns to its original position, and the sorting operation ends.

[0040] S5: Large Item Push For large items, pusher plate 402 pushes them onto loading rack 603 of the transfer assembly. Rightmost stop bar 606 limits the movement of the package to prevent excessive movement. Pusher plate 402 returns to its original position after pushing.

[0041] S6: Return Confirmation and Transfer Initiation After returning to its original position, the push plate 402 approaches the positioning detection sensor 404 mounted on the housing of the servo cylinder 401. The sensor sends a positioning completion signal to the controller. Upon receiving the signal, the controller starts the servo motor 604, driving the rotating frame 602 to rotate.

[0042] S7: Smooth Transfer of Large Items The two rotating frames 602 rotate synchronously in the same direction (each rotation is a quarter turn), and the loading frame 603 keeps the bearing surface facing upward under geometric constraints, so as to move the large-volume express from the high position to the lowest side position.

[0043] S8: Express Delivery and Downstream Transportation When the loading frame 603 rotates to its lowest side, the trough in its middle section accommodates the second electric conveyor roller 702. The express delivery bottom surface contacts the continuously operating second electric conveyor roller 702 and is moved by the roller onto the belt conveyor 703, ultimately being transported downstream. The loading frame 603 continues to rotate unloaded, entering the next work cycle.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
