Description

Technical Field

[0001] The present invention belongs to the technical field of conveying devices, and particularly relates to an intelligent in-out production line and an in-out method. Background Art

[0002] The storage of track train parts plays an important role in the manufacturing and maintenance of rail transit equipment. The coherence and automation level of its storage process directly affect production efficiency. The traditional storage method commonly adopted in the current industry is: directly stacking parts on pallets, relying on manual handling one by one and placing them in scattered storage boxes. The entire process does not form a systematic production line operation, revealing the following core defects: Non-assembly line operation leads to extremely low efficiency There is a lack of a continuous material flow conveying system in the transfer process of parts from the pallet to the storage box. Workers need to frequently shuttle between the pallet stacking area and the storage box placement point. The single-part storage needs to go through multiple independent links such as "fetching parts → walking → sorting → placing", and the average time-consuming is more than 50% longer than that of the assembly line operation. For example, in the storage scenario of subway vehicle bogie parts, a single worker can only complete the classified storage of about 20 parts per hour. The storage of parts relies on multiple workstations working independently, lacking unified rhythm control and process connection, which is prone to cause operation chaos and a sharp drop in efficiency. Summary of the Invention

[0003] In view of this, the present invention provides a roller conveyor for a track part cargo box to solve the problem that in the prior art, the whole process does not form a systematic production line operation when track train parts are put into the storage box.

[0004] The technical solution adopted by the present invention is as follows: An intelligent in-out production line, comprising: A first roller conveyor, with a second roller conveyor and a third roller conveyor respectively docked at both ends of the first roller conveyor. The second roller conveyor and the third roller conveyor are respectively perpendicular to the first roller conveyor. A conveying device is provided on the first roller conveyor, and the conveying device is used to transfer the storage box on the first roller conveyor to the third roller conveyor; A mobile vehicle and a storage rack. A plurality of support plates are supported on the mobile vehicle through a material rack. The plurality of support plates are arranged at intervals along the height direction of the material rack. A transfer device is also provided on the mobile vehicle, and the transfer device is used to transport the storage box on the third roller conveyor to the support plate; A plurality of storage stations for placing storage boxes are provided on the storage rack. The mobile vehicle can move to one side of the storage rack and transport the storage box on the support plate to the corresponding storage station through the transfer device; A control system for controlling the operation of a first roller conveyor, a second roller conveyor, a third roller conveyor, a mobile vehicle, and a transfer device.

[0005] In this technical solution, it should be noted that the first roller conveyor serves as the main conveying channel, receiving the storage boxes from the second roller conveyor and conveying them towards the third roller conveyor. The conveying device thereon is responsible for laterally transferring the storage boxes to the vertical third roller conveyor. Realizing the linear transmission of the storage boxes in the horizontal direction and cross-direction transfer is the core transmission hub of the entire system. The second roller conveyor is vertically docked with the first roller conveyor, conveying the storage boxes to the first roller conveyor and providing the initial input path for the storage boxes, expanding the material access direction of the system. The third roller conveyor is vertically docked with the first roller conveyor, receiving the storage boxes transferred by the conveying device and conveying them towards the mobile vehicle direction, connecting the first roller conveyor and the mobile vehicle, and providing a transition channel for the storage boxes to enter the mobile vehicle. The mobile vehicle moves through the bottom drive mechanism. The support plates on the material rack are used to temporarily store the storage boxes, and the transfer device is responsible for picking up the boxes from the third roller conveyor and placing them on the storage rack. The storage rack is provided with multiple storage stations (such as grid cabinets, tray positions) for fixedly storing the storage boxes. The control system uniformly controls the start and stop, speed of the first / second / third roller conveyors, the path planning and positioning of the mobile vehicle, and the grasping and handling actions of the transfer device, coordinating the synchronous operation of each device to ensure seamless automation of the entire process and improving the stability and efficiency of the system. The working principle of the present invention is as follows: The storage boxes are conveyed from the second roller conveyor (perpendicular to the first roller conveyor) to the entrance of the first roller conveyor. After the staff places the parts into the storage boxes beside, the first roller conveyor starts and conveys the storage boxes along the main path to the designated position of the conveying device. The conveying device acts to transfer the storage boxes from the first roller conveyor to the vertical third roller conveyor, and the third roller conveyor continues to convey the storage boxes towards the mobile vehicle direction after receiving them. The mobile vehicle travels to the end of the third roller conveyor for docking, and the transfer device transfers the storage boxes to the multi-layer support plates on the mobile vehicle, completing one picking operation. After the mobile vehicle is fully loaded, it moves to one side of the storage rack, and the transfer device layer by layer conveys the storage boxes on the support plates to the corresponding stations on the storage rack (such as storing them according to the floor height matching), realizing the orderly storage of the parts. The control system real-time monitors the status of each device (such as the position of the storage boxes, the coordinates of the mobile vehicle) through sensors, and coordinates the start and stop timing of the roller conveyors, the path planning of the mobile vehicle, and the action accuracy of the transfer device through program logic to ensure no jams in the entire process. In the present invention, the three-dimensional layout of the multi-layer support plates and the storage rack stations saves more than 50% of the space compared to planar storage, and is suitable for compact warehousing environments. There is no need for manual handling from the feeding of the storage boxes to the storage process, reducing labor costs and reducing human operation errors (such as missing parts placement, storage misalignment). The roller conveyor and the mobile vehicle operate in parallel, and with the fast picking and placing of the transfer device, the efficiency is significantly improved compared to traditional manual labor. The control system can record the position and part information of each storage box, support real-time inventory query and traceability, and improve the accuracy and traceability of material management.

[0006] Preferably, a first guide rail is provided on one side of the material rack, the first guide rail is arranged vertically, and a first electric slide slidably connected to the first guide rail; the transfer device includes a base support, the base support is arranged on the first electric slide, the top of the base support is rotatably connected to a support plate, and the support plate is driven by a first motor provided on the base support to rotate. The two sides of the support plate are fixedly connected to the second guide rail, the second guide rail is arranged horizontally, and the second electric slide is slidably connected to the second guide rail, and the two second electric slides are connected by a card plate toward one end of the material rack, and one end of the second electric slide is rotatably connected to a push plate, and the push plate is driven by a second motor provided on the second electric slide to rotate, and the end of the push plate extends to one side of the second electric slide along the width direction of the second electric slide; the first motor and the second motor are controlled by a control system.

[0007] In this technical solution, it should be noted that, in this automated storage system, the first guide rail is vertically arranged on one side of the material rack, providing a vertical guide rail for the second electric slide rail, so that it drives the bottom support to rise and fall in the vertical direction, so as to realize the precise alignment of the support plate with the third roller conveyor, support plate or storage rack station of different heights; the bottom support is installed at the front end of the second electric slide rail as the installation base of the support plate, and the support plate on its top can be rotated 0-180° by the first motor to adjust the direction of the storage box (such as turning it to be parallel to the conveying direction of the third roller conveyor when taking the box), ensuring that the storage box can be aligned with the target position; the second guide rail is laterally fixed on both sides of the support plate to form a lateral moving track, which is directed toward the material rack. The two ends are connected by a card plate, which serves as a rigid supporting structure and cooperates with the push plate when pushing the storage box. After the push plate releases the limit on the storage box, the card plate moves laterally through the second electric slide rail to smoothly push the storage box on the support plate to the support plate; the second electric slide rail is slidably connected to the second guide rail, and the push plate at one end is driven by the second motor to rotate 0-90°. When taking the box, the push plate first rotates to a vertical state (offset from the storage box on the third roller conveyor), and then the second electric slide rail drives the push plate to move laterally to the back of the storage box. The push plate rotates to a horizontal state and clamps the back side of the box body. The second electric slide rail moves in the opposite direction to pull the storage box to the support plate. When placing the box, the push plate rotates to release the limit and cooperates with the card plate to complete the pushing. The overall principle is: the mobile car moves to the side of the third roller conveyor, the second electric slide adjusts the height of the support plate so that the support plate is conveyed and aligned with the third roller, the support plate rotates to a parallel direction, the push plate vertically avoids the storage box and moves horizontally to the back of the box body through the second electric slide, rotates horizontally to clamp the box body and pulls it to the support plate through the reset movement of the second electric slide; then the bottom bracket is raised and lowered to the corresponding support plate height, the support plate rotates 180° to align with the support plate, the push plate rotates to release the limit, and the second electric slide drives the card plate to push the storage box to the support plate; when the storage box needs to be transferred to the storage rack, the mobile car moves to the side of the storage rack and repeats similar actions. By clamping the push plate, rotating the support plate, and pushing the card plate, the storage box is accurately pushed into the storage station. Beneficial effects: Through the multi-dimensional coordination of vertical lifting, lateral movement, and angular rotation, each component can realize the flexible transportation of storage boxes in three-dimensional space. The division of labor and cooperation between the pallet and the push plate ensures a stable and offset-free pushing process. The automated process reduces manual intervention and improves transportation efficiency (short single cycle time). The precise positioning reduces the risk of collision damage to the storage boxes and enhances system reliability and space utilization.

[0008] Preferably, the third roller conveyor is supported by a mounting frame. A vertical plate is slidably connected to one side of the mounting frame away from the first roller conveyor. The top of the vertical plate is higher than the top of the conveying surface of the third roller conveyor, and the vertical plate is elastically connected to the mounting frame by a first spring. First guiding surfaces are provided at both ends of the top of the vertical plate. The first guiding surfaces are inclined upward in the direction close to the first roller conveyor, and the first guiding surfaces face the second electric slide rail.

[0009] In this technical solution, it should be noted that the third roller conveyor is supported by a mounting frame. A vertical plate is slidably connected to one side of the mounting frame away from the first roller conveyor. The top of the vertical plate is higher than the conveying surface. The vertical plate is elastically connected to the mounting frame by a first spring. First guiding surfaces (inclined upward in the direction of the first electric slide rail) are provided at both ends of the top. Under normal conditions, the vertical plate blocks the storage box on the third roller conveyor to prevent it from slipping prematurely; when the second electric slide rail moves towards the inner side of the third roller conveyor, the end of it presses the first guiding surface of the vertical plate, forcing the vertical plate to move downward against the elastic force of the first spring, releasing the block on the storage box, so that the storage box can be pulled to the supporting plate by the pushing plate; after the storage box is removed, the vertical plate automatically resets under the action of the first spring and continues to block the subsequent storage boxes, realizing the release of each box one by one. This design uses the cooperation of the elastic vertical plate and the guiding surface to realize the automatic limiting and release of the storage box through a mechanical structure without an additional power source.

[0010] Preferably, limiting rods are respectively supported above both sides of the mounting frame by support rods. The limiting rods are arranged along the length direction of the third roller conveyor. A guiding rod is provided at the bottom of the support rod. The guiding rod slidably passes through the mounting frame and extends to the lower part of the third roller conveyor. A second spring is sleeved on the guiding rod. One end of the second spring is connected to the mounting frame, and the other end is connected to the guiding rod; a wedge-shaped block is provided at the bottom of the vertical plate. Second guiding surfaces are respectively provided at both ends in the width direction of the wedge-shaped block. The second guiding surfaces are inclined downward in the direction close to the corresponding guiding rod from top to bottom, and the second guiding surfaces are in contact with the corresponding guiding rods.

[0011] In this technical solution, it's important to note that the support rods on either side of the mounting frame connect the limit rods and guide rods, allowing the limit rods to move horizontally with the guide rods. The limit rods restrict the lateral position of the storage boxes along the length of the third roller conveyor. The guide rods extend through the mounting frame and are protected by a second spring (one end connected to the mounting frame and the other to the guide rods). Under normal conditions, the springs support the guide rods to maintain their initial spacing. Second guide surfaces (inclined toward the guide rods from top to bottom) are provided at each end of the wedge-shaped block at the bottom of the riser, contacting the guide rods. Key features: When the riser, squeezed downward by the second motorized slide, moves the wedge block downward with it, gradually releasing its inclined second guide surface from its horizontal support for the guide rod. Initially, the guide rod rests against the higher portion of the second guide surface due to spring force. The spring is compressed, providing outward thrust. As the wedge block moves downward, the contact point between the guide rod and the second guide surface shifts toward the narrower portion of the second guide surface, reducing the horizontal support force of the inclined surface. The spring force causes the guide rod to actively move toward the center of the mounting frame, driving the stop rods inward through the support rods, pushing the storage box to the center. When the riser returns to its original position, the wedge block moves upward, restoring the horizontal support force of the second guide surface, pushing the guide rods outward again, and restoring the spacing between the stop rods. This design offers several advantages: Automatic centering of the storage box is achieved through a purely mechanical mechanism, eliminating the need for additional sensors and control systems, reducing equipment cost and maintenance. The cushioning effect of the second spring prevents rigid collisions between the stop rods and the storage box, effectively protecting the box surface.

[0012] Preferably, two ends of the storage box in the length direction are provided with a QR code, and a scanner is provided on the mobile vehicle. The scanner transmits the scanned QR code to the control system. The control system obtains the information of the storage box through the QR code, and transports the storage box to the storage rack through the transfer device, and records the storage information.

[0013] In this technical solution, it should be noted that two-dimensional codes are provided at both ends of the storage box in the length direction. Its function is to store the detailed information of the items in the storage box, including but not limited to item name, specification model, quantity, production date, shelf life, etc., and assign a unique digital identity identifier to each storage box. The scanner equipped on the mobile vehicle is responsible for quickly scanning and identifying the two-dimensional codes of the passing storage boxes, and converting the obtained two-dimensional code image information into readable data signals. The scanner transmits the scanned two-dimensional code data to the control system in real time. As the "brain" of the entire device, the control system analyzes and processes the data, and obtains all the information of the storage box through the coding rules in the two-dimensional code, including the target storage location, storage condition requirements, etc. According to this information, the control system precisely controls the various components of the transfer device to work together, such as adjusting the height of the supporting plate, controlling the actions of the pushing plate and the clamping plate, adjusting the rotation angle of the supporting plate, etc., and accurately conveys the storage box to the corresponding designated position on the storage rack. At the same time, the control system will record the storage information such as the storage location and storage time of the storage box, forming a complete warehousing data record, which is convenient for subsequent operations such as quickly retrieving, inventorying, and out-of-storage of items. The beneficial effect of this design is to achieve a high degree of informatization and automation of warehousing management. Through the cooperation of the two-dimensional code and the scanner, the error rate and time cost of manual information entry are greatly reduced, and the accuracy and efficiency of warehousing operations are improved; the recording of storage information by the control system is convenient for warehouse managers to grasp the inventory status in real time, optimize the utilization of warehousing space, and realize intelligent inventory management; and it can flexibly adjust the storage strategy according to different information of the storage box, meet diverse warehousing needs, and improve the intelligent level and adaptability of the entire warehousing system.

[0014] Preferably, the first roller conveyor slopes downward in the direction away from the second roller conveyor. The number of the conveying devices is several. The conveying directions of the several conveying devices are the same as the conveying direction of the third roller conveyor, and the several conveying devices are located on the side of the third roller conveyor facing the first roller conveyor. The several conveying devices are respectively arranged at the gaps between two adjacent rollers on the first roller conveyor; a lifting device for lifting the conveying device is further provided on the first roller conveyor.

[0015] In this technical solution, it should be noted that the first roller conveyor slopes downward in the direction away from the second roller conveyor, causing the storage box to tilt with the rollers, expanding the visible area inside the box, facilitating workers to stand on one side to observe and load parts, and improving the operation convenience. The number of conveying devices is several, and their conveying directions are consistent with that of the third roller conveyor, all arranged along the main direction of material conveyance. Moreover, these conveying devices are located on the side of the third roller conveyor facing the first roller conveyor and are respectively installed at the gaps between adjacent rollers on the first roller conveyor. The lifting device equipped on the first roller conveyor is used to drive the conveying device to perform lifting motion. When it is necessary to transfer materials from the first roller conveyor to the third roller conveyor, the lifting device raises the conveying device so that its conveying surface is higher than the top of the rollers of the first roller conveyor. At this time, the materials can smoothly transition from the first roller conveyor to the conveying device and then continue to be conveyed to the third roller conveyor by the conveying device; when material transfer is not required, the lifting device lowers the conveying device so that its conveying surface is lower than the top of the rollers of the first roller conveyor, avoiding affecting the normal conveying operation of the first roller conveyor. The beneficial effect of this design lies in that by arranging a liftable conveying device at the roller gaps of the first roller conveyor, the spatial layout of the equipment is cleverly utilized to achieve efficient connection between the two conveyors, avoiding problems such as material jamming or dropping that may occur in traditional transfer methods; the design of the lifting device enables the conveying device to rise and work when needed and lower and hide when not needed, without affecting the original function of the first roller conveyor, improving the space utilization rate and flexibility of the equipment.

[0016] Preferably, each conveying device is installed on a bracket, the bottoms of each of the brackets are connected by a connecting plate, one end of the connecting plate close to the third roller conveyor is hinged to the frame of the first roller conveyor, and the lifting device rotates the connecting plate to achieve the lifting of the conveying device.

[0017] In this technical solution, it should be noted that each conveying device is mounted and fixed by a bracket. The bottom of each bracket is connected to each other by a connecting plate. The end of the connecting plate near the third roller conveyor forms a hinged structure with the frame of the first roller conveyor. The lifting device drives the connecting plate to rotate about the hinge point to achieve the lifting and lowering of the conveying device. When the lifting device applies driving force, the connecting plate rotates upward about the hinge point, driving each bracket and the conveying device mounted thereon to rise synchronously, raising the conveying surface of the conveying device above the top of the roller of the first roller conveyor, thereby receiving and conveying material. When the lifting device reverses, the connecting plate rotates downward about the hinge point, lowering the conveying device and lowering the conveying surface below the top of the roller to avoid interfering with the normal operation of the first roller conveyor. Through the linkage design of the hinge and the connecting plate, this structure converts the driving force of the lifting device into the rotational lifting motion of the conveying device. The leveraging principle of the hinge point effectively reduces driving energy consumption while ensuring the synchronous operation of multiple conveying devices, achieving smooth material transfer between different conveyors, improving equipment space utilization and operational reliability. The simple and compact structure is easy to maintain and operate.

[0018] Preferably, the lifting device includes a cam, the cam is rotatably connected to the frame via a rotating shaft, the cam is in contact with the bottom of the connecting plate, and the rotating shaft is driven by a motor provided on the frame.

[0019] In this technical solution, it should be noted that the cam in the lifting mechanism is connected to the frame via a rotating shaft. When the motor drives the shaft to rotate, the cam rotates synchronously. Due to the cam's profile, when it contacts the bottom of the connecting plate, the cam's profile changes its contact position with the connecting plate as the rotation angle changes, thereby driving the connecting plate to rotate about its hinge point with the frame. When the distal end of the cam gradually contacts the connecting plate, the connecting plate is lifted upward, driving the conveyor to its working position. When the proximal end of the cam contacts the connecting plate, the connecting plate falls back under the action of gravity or a return spring, lowering the conveyor to its hidden position. This design converts circular motion into oscillation of the connecting plate by the motor-driven rotation of the cam, thereby achieving the lifting and lowering of the conveyor. The structure is simple and compact, and the cam profile can be used to precisely control the lifting stroke and rest position. The motor can flexibly adjust the conveyor's operating state through forward, reverse, or intermittent drive to meet different working conditions. The cam mechanism also has a self-locking function that maintains the conveyor's current position in the event of a power outage or drive stop, improving the stability and safety of the equipment.

[0020] Preferably, the conveying device is a belt conveyor.

[0021] An intelligent warehousing and warehousing method, comprising: Step 1: The storage box is conveyed to the first roller conveyor by the second roller conveyor perpendicular to the first roller conveyor. The staff places the corresponding parts into the storage box on one side of the first roller conveyor, and then the first roller conveyor starts to move the storage box to the designated position. Step 2: The conveying device on the first roller conveyor laterally transfers the storage box to the perpendicular third roller conveyor, and the third roller conveyor continues to convey the storage box after receiving it. Step 3: The mobile vehicle drives to the side of the third roller conveyor, and the transfer device transfers the storage box on the third roller conveyor to the support plate of the mobile vehicle. Step 4: The mobile vehicle moves to one side of the storage rack, and the transfer device successively transports the storage boxes on the support plate to the corresponding storage stations of the storage rack. Among them, the control system coordinates and controls the start-stop, speed and actions of each device to ensure the automatic connection of the storage box loading, transfer and storage processes.

[0022] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: 1. In the present invention, the three-dimensional layout of the multi-layer support plate and the storage rack stations saves more than 50% of the space compared with the plane storage, and is suitable for a compact warehousing environment. There is no need for manual handling from the storage box loading to the storage process, which reduces the labor cost and reduces the human operation error (such as missing parts placement and storage misalignment). The roller conveyor and the mobile vehicle operate in parallel, and with the quick pick-up and placement of the transfer device, the efficiency is significantly improved compared with the traditional manual operation. The control system can record the position and part information of each storage box, support real-time inventory query and traceability, and improve the accuracy and traceability of material management. 2. In the present invention, through the multi-dimensional cooperation of vertical lifting, lateral movement and angular rotation of each component, the flexible handling of the storage box in the three-dimensional space is realized. The division of labor and cooperation between the pallet and the push plate ensure the stability and non-offset of the pushing process. The automated process reduces manual intervention, improves the transfer efficiency (short single-cycle time), and the precise positioning reduces the risk of collision damage to the storage box, enhancing the system reliability and space utilization rate. 3. In the present invention, through the cooperation of the two-dimensional code and the scanner, the error rate and time cost of manual information entry are greatly reduced, and the accuracy and efficiency of warehousing operations are improved; the control system's recording of storage information facilitates warehouse managers to grasp the inventory status in real time, optimize the utilization of warehousing space, and realize intelligent inventory management; and it can flexibly adjust the storage strategy according to different information of the storage box to meet diverse warehousing needs, improving the intelligent level and adaptability of the entire warehousing system. 4. In the present invention, when the riser is pushed downward by the second electric slide, the wedge block moves downward with it, and its inclined second guide surface gradually disengages from its horizontal support for the guide rod. Initially, the guide rod rests against the higher portion of the second guide surface due to the spring force. At this point, the spring is compressed, providing an outward thrust. As the wedge block moves downward, the contact point between the guide rod and the second guide surface shifts toward the narrower portion of the second guide surface, reducing the horizontal support force of the inclined surface. Under the action of the spring force, the guide rod actively moves toward the center of the mounting frame, driving the stop rods inward synchronously via the support rods, pushing the storage box to the center. When the riser returns to its original position and the wedge block moves upward, the horizontal support force of the second guide surface is restored, pushing the guide rods outward again, and restoring the spacing between the stop rods. This design offers the following advantages: automatic centering of the storage box is achieved through a purely mechanical structure, eliminating the need for additional sensors and control systems, reducing equipment cost and maintenance. The cushioning effect of the second spring prevents rigid collision between the stop rods and the storage box, effectively protecting the box surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiment 1 As Figure 1-10 shown, an intelligent in-out production line is disclosed in an embodiment of the present invention, including: A first roller conveyor 1, with a second roller conveyor 2 and a third roller conveyor 3 respectively docked at both ends of the first roller conveyor 1. The second roller conveyor 2 and the third roller conveyor 3 are respectively perpendicular to the first roller conveyor 1. A conveying device 7 is provided on the first roller conveyor 1, and the conveying device 7 is used to transfer the storage box 4 on the first roller conveyor 1 to the third roller conveyor 3; A mobile vehicle 5 and a storage rack. A plurality of support plates 9 are supported on the mobile vehicle 5 through a material rack 8. The plurality of support plates 9 are arranged at intervals along the height direction of the material rack 8. A transfer device 6 is also provided on the mobile vehicle 5, and the transfer device 6 is used to transport the storage box 4 on the third roller conveyor 3 to the support plate 9; A plurality of storage stations for placing the storage box 4 are provided on the storage rack.

[0031] It should be noted that the first roller conveyor 1 serves as the main conveying channel, receiving the storage box 4 of the second roller conveyor 2 and conveying it towards the third roller conveyor 3. The conveying device 7 thereon is responsible for laterally transferring the storage box 4 to the vertical third roller conveyor 3. Realizing the linear transmission of the storage box 4 in the horizontal direction and cross-direction transfer is the core transmission hub of the entire system. The second roller conveyor 2 is vertically docked with the first roller conveyor 1, conveying the storage box 4 to the first roller conveyor 1, providing the initial input path of the storage box 4, and expanding the material access direction of the system.

The mobile vehicle 5 moves through the bottom drive mechanism. The support plate 9 on the material rack 8 is used for temporarily storing the storage box 4. The transfer device 6 is responsible for picking up the box from the third roller conveyor 3 and placing the box on the storage rack. The storage rack is provided with multiple storage stations (such as grid cabinets, pallet positions) for fixedly storing the storage box 4. The control system uniformly controls the start and stop, speed of the first / second / third roller conveyors, the path planning and positioning of the mobile vehicle 5, and the grasping and handling actions of the transfer device 6, coordinates the synchronous operation of each device, ensures the full-process automatic connection, and improves the stability and efficiency of the system. The working principle of the present invention is as follows: The storage box 4 is conveyed from the second roller conveyor 2 (perpendicular to the first roller conveyor 1) to the entrance of the first roller conveyor 1. After the staff places parts into the storage box 4 beside it, the first roller conveyor 1 starts and conveys the storage box 4 along the main path to the designated position of the conveying device 7. The conveying device 7 operates to transfer the storage box 4 from the first roller conveyor 1 to the vertical third roller conveyor 3, and the third roller conveyor 3 continues to convey the storage box 4 towards the mobile vehicle 5 after receiving it. The mobile vehicle 5 travels to the end of the third roller conveyor 3 for docking, and the transfer device 6 transfers the storage box 4 to the multi-layer support plate 9 of the mobile vehicle 5 to complete one picking operation. After the mobile vehicle 5 is fully loaded, it moves to one side of the storage rack, and the transfer device 6 layer by layer conveys the storage box 4 on the support plate 9 to the corresponding station of the storage rack (such as storing according to the floor height matching), realizing the orderly storage of parts. The control system real-time monitors the states of each device (such as the position of the storage box 4, the coordinates of the mobile vehicle 5) through sensors, and coordinates the start and stop sequence of the roller conveyor, the path planning of the mobile vehicle 5 and the action accuracy of the transfer device 6 through program logic to ensure that there is no jam in the full process. In the present invention, the three-dimensional layout of the multi-layer support plate 9 and the storage rack stations saves more than 50% of the space compared with planar storage, and is suitable for a compact warehousing environment. There is no need for manual handling from the feeding of the storage box 4 to the storage process, reducing labor costs and reducing human operation errors (such as missing parts placement, storage misalignment). The roller conveyor and the mobile vehicle 5 operate in parallel, and with the rapid picking and placing of the transfer device 6, the efficiency is significantly improved compared with traditional manual work.The control system can record the position and part information of each storage box 4, support real-time inventory query and traceability, and improve the accuracy and traceability of material management.

[0032] Embodiment 2 Such as Figures 2-4As shown, this embodiment is substantially the same as the above embodiment, except that a first guide rail 10 is provided on one side of the material rack 8, the first guide rail 10 is vertically arranged, and a first electric slide rail 11 is provided on the first guide rail 10 for sliding connection therewith; the adapter 6 includes a bottom bracket 18, the bottom bracket 18 is arranged on the first electric slide rail 11, the top of the bottom bracket 18 is rotatably connected to a supporting plate 12, the supporting plate 12 is driven by a first motor provided on the bottom bracket 18 to realize rotation, and both sides of the supporting plate 12 are fixedly connected to the bottom plate The second guide rail 13 is arranged horizontally, and a second electric slide rail 14 is slidably connected to the second guide rail 13. The two second electric slide rails 14 are connected by a clamping plate 15 at one end facing the material rack 8. One end of the second electric slide rail 14 is rotatably connected to a push plate 16, and the push plate 16 is driven by a second motor provided on the second electric slide rail 14 to realize rotation, and the end of the push plate 16 extends to one side of the second electric slide rail 14 along the width direction of the second electric slide rail 14; the first motor and the second motor are controlled by a control system. It should be noted that, in this automated storage system, the first guide rail 10 is vertically arranged on one side of the material rack 8, providing a vertical guide rail for the second electric slide rail 14, so that it drives the bottom support 18 to rise and fall in the vertical direction, so as to realize the precise alignment of the support plate 12 with the third roller conveyor 3, the support plate 9 or the storage rack station of different heights; the bottom support 18 is installed at the front end of the second electric slide rail 14, serving as the installation base of the support plate 12, and the support plate 12 on its top can be rotated 0-180° by the first motor to adjust the direction of the storage box 4 (such as turning it to be parallel to the conveying direction of the third roller conveyor 3 when taking the box), ensuring that the storage box 4 can be aligned with the target position; the second guide rail 13 is laterally fixed on both sides of the support plate 12 to form a transverse moving track, and its end toward the material rack 8 is connected by a card plate 15, and the card plate 15 serves as a rigid supporting structure, which cooperates with the push plate 16 when pushing the storage box 4. When the push plate 16 releases the limit on the storage box 4, the card plate 15 pushes the storage box 4 on the supporting plate 12 smoothly to the support plate 9 through the lateral movement of the second electric slide rail 14; the second electric slide rail 14 is slidably connected to the second guide rail 13, and the push plate 16 at one end thereof is driven by the second motor to rotate 0-90°. When taking the box, the push plate 16 first rotates to a vertical state (offset from the storage box 4 on the third roller conveyor 3), and then the second electric slide rail 14 drives the push plate 16 to move horizontally to the back of the storage box 4, and the push plate 16 rotates to a horizontal state to clamp the back side of the box body. The second electric slide rail 14 moves in the opposite direction to pull the storage box 4 to the supporting plate 12. When placing the box, the push plate 16 rotates to release the limit and cooperates with the card plate 15 to complete the pushing.Overall principle: The mobile vehicle 5 travels to the side of the third roller conveyor 3. The second electric slide rail 14 adjusts the height of the support plate 12 to align the support plate 12 with the third roller conveyor. The support plate 12 rotates to the parallel direction. The push plate 16 vertically avoids the storage box 4 and then horizontally moves to the rear of the box body through the second electric slide rail 14. It rotates to horizontally clamp the box body and is pulled to the support plate 12 through the reset movement of the second electric slide rail 14. Subsequently, the bottom support 18 is lifted or lowered to the height of the corresponding support plate 9. The support plate 12 rotates 180° to align with the support plate 9. The push plate 16 rotates to release the limit. The second electric slide rail 14 drives the clamping plate 15 to push the storage box 4 to the support plate 9. When it is necessary to transfer the storage box 4 to the storage rack, the mobile vehicle 5 moves to the side of the storage rack and repeats similar actions. Through the clamping of the push plate 16, the rotation of the support plate 12, and the pushing of the clamping plate 15, the storage box 4 is accurately pushed into the storage station. Beneficial effects: Each component cooperates in multiple dimensions of vertical lifting, horizontal movement, and angular rotation to achieve the flexible handling of the storage box 4 in three-dimensional space. The division of labor and cooperation between the clamping plate 15 and the push plate 16 ensure a stable and non-offset pushing process. The automated process reduces manual intervention, improves the transfer efficiency (short single-cycle time), and the accurate positioning reduces the risk of collision damage to the storage box 4, enhancing the system reliability and space utilization rate.

[0033] Embodiment 3 As Figures 5-7 shown, this embodiment is substantially the same as the above embodiment. The difference is that the third roller conveyor 3 is supported by the mounting frame 17. A vertical plate 33 is slidably connected to the side of the mounting frame 17 away from the first roller conveyor 1. The top of the vertical plate 33 is higher than the top of the conveying surface of the third roller conveyor 3. And the vertical plate 33 is elastically connected to the mounting frame 17 through the first spring 26. Both ends of the top of the vertical plate 33 are provided with the first guiding surfaces 19. The first guiding surfaces 19 are inclined upward along the direction close to the first roller conveyor 1. And the first guiding surfaces 19 face the second electric slide rail 14. It should be noted that the third roller conveyor 3 is supported by the mounting frame 17. The vertical plate 33 is slidably connected to the side of the mounting frame 17 away from the first roller conveyor 1. The top of the vertical plate 33 is higher than the conveying surface. It is elastically connected to the mounting frame 17 through the first spring 26. The first guiding surfaces 19 are provided at both ends of the top. Under normal conditions, the vertical plate 33 blocks the storage box 4 on the third roller conveyor 3 to prevent it from slipping in advance. When the second electric slide rail 14 moves towards the inner side of the third roller conveyor 3, its end presses the first guiding surface 19 of the vertical plate 33, forcing the vertical plate 33 to move downward against the elastic force of the first spring 26, releasing the block on the storage box 4, so that the storage box 4 can be pulled to the support plate 12 by the push plate 16. After the storage box 4 is removed, the vertical plate 33 automatically resets under the action of the first spring 26 and continues to block the subsequent storage boxes 4, realizing the release of each box one by one. This design uses the cooperation of the elastic vertical plate 33 and the guiding surface, and uses the mechanical structure to realize the automatic limiting and release of the storage box 4 without an additional power source.

[0034] As Figures 5-7 shown, in this embodiment, on both sides above the mounting frame 17, limiting rods 20 are respectively supported by support rods 21. The limiting rods 20 are arranged along the length direction of the third roller conveyor 3. At the bottom of the support rods 21, guide rods 22 are provided. The guide rods 22 slidably pass through the mounting frame 17 and extend below the third roller conveyor 3. A second spring 23 is sleeved on the guide rods 22. One end of the second spring 23 is connected to the mounting frame 17, and the other end is connected to the guide rods 22. At the bottom of the vertical plate 33, a wedge-shaped block 24 is provided. At both ends in the width direction of the wedge-shaped block 24, second guiding surfaces 25 are provided. The second guiding surfaces 25 are inclined downward along the direction close to the corresponding guide rods 22 from top to bottom, and the second guiding surfaces 25 are in contact with the corresponding guide rods 22. It should be noted that the support rods 21 on both sides above the mounting frame 17 are used to connect the limiting rods 20 and the guide rods 22, so that the limiting rods 20 can move horizontally along with the guide rods 22. The limiting rods 20 limit the lateral position of the storage box 4 along the length direction of the third roller conveyor 3. The guide rods 22 pass through the mounting frame 17 and are sleeved with the second spring 23 (one end is connected to the mounting frame 17 and the other end is connected to the guide rods 22). In the normal state, the spring pushes the guide rods 22 apart to keep the limiting rods 20 at the initial spacing. At both ends of the wedge-shaped block 24 at the bottom of the vertical plate 33, second guiding surfaces 25 are provided (inclined downward to the guide rods 22 from top to bottom) and are in contact with the guide rods 22. Key function: When the vertical plate 33 is squeezed downward by the second electric slide rail 14, the wedge-shaped block 24 moves downward accordingly, and its inclined second guiding surface 25 gradually disengages from the horizontal support of the guide rods 22. In the initial state, the guide rods 22 are abutted against the higher position of the second guiding surface 25 due to the spring force. At this time, the spring is in a compressed state and provides an outward thrust. As the wedge-shaped block 24 moves downward, the contact point between the guide rods 22 and the second guiding surface 25 changes to the narrower part of the second guiding surface 25, and the horizontal supporting force of the inclined surface decreases. The guide rods 22 actively move toward the center of the mounting frame 17 under the action of the spring force, and drive the limiting rods 20 to contract synchronously through the support rods 21, pushing the storage box 4 to the center. When the vertical plate 33 is reset, the wedge-shaped block 24 moves upward, the horizontal supporting force of the second guiding surface 25 is restored, the guide rods 22 are pushed back to the outside again, and the spacing between the limiting rods 20 is restored. The beneficial effects brought by this design include: realizing the automatic centering and positioning of the storage box 4 through a pure mechanical structure, without the need for additional sensors and control systems, reducing the equipment cost and maintenance difficulty; the buffering effect of the second spring 23 avoids the rigid collision between the limiting rods 20 and the storage box 4, effectively protecting the surface of the box body.

[0035] Embodiment 4 This embodiment is substantially the same as the above-mentioned embodiment, except that two ends in the length direction of the storage box 4 are provided with two-dimensional codes, a scanner is provided on the mobile vehicle 5, the scanner transmits the scanned two-dimensional code to the control system, the control system obtains the information of the storage box 4 through the two-dimensional code, and conveys the storage box 4 to the storage rack through the transfer device 6 and records the storage information. It should be noted that the two-dimensional codes are arranged at two ends in the length direction of the storage box 4, and their function is to store the detailed information of the items in the storage box 4, including but not limited to item name, specification model, quantity, production date, shelf life, etc., and endow each storage box 4 with a unique digital identity identifier. The scanner equipped on the mobile vehicle 5 is responsible for quickly scanning and identifying the two-dimensional code of the passing storage box 4, and converting the obtained two-dimensional code image information into a readable data signal. The scanner transmits the scanned two-dimensional code data to the control system in real time. As the "brain" of the entire device, the control system analyzes and processes the data, and obtains all the information of the storage box 4 through the coding rules in the two-dimensional code, including the target storage position, storage condition requirements, etc. According to this information, the control system accurately controls the various components of the transfer device 6 to work together, such as adjusting the height of the support plate 12, controlling the actions of the push plate 16 and the clamping plate 15, adjusting the rotation angle of the support plate 12, etc., and conveys the storage box 4 to the corresponding designated position on the storage rack accurately. At the same time, the control system will record the storage information such as the storage location and storage time of the storage box 4 to form a complete warehousing data record, which is convenient for subsequent operations such as quick retrieval, inventory checking, and outbound of items. The beneficial effect of this design is to realize a high degree of informatization and automation of warehousing management. Through the cooperation of the two-dimensional code and the scanner, the error rate and time cost of manual information entry are greatly reduced, and the accuracy and efficiency of warehousing operations are improved; the recording of storage information by the control system is convenient for warehouse managers to grasp the inventory status in real time, optimize the utilization of warehousing space, and realize intelligent inventory management; and it can flexibly adjust the storage strategy according to the different information of the storage box 4 to meet diverse warehousing needs, and improve the intelligent level and adaptability of the entire warehousing system.

[0036] Embodiment 5 As Figures 8-10As shown, this embodiment is substantially the same as the above embodiment, except that there are several conveying devices 7, the conveying directions of the several conveying devices 7 are the same as the conveying direction of the third roller conveyor 3, and the several conveying devices 7 are located on the side of the third roller conveyor 3 facing the first roller conveyor 1. The several conveying devices 7 are respectively arranged at the gaps between two adjacent rollers on the first roller conveyor 1; a lifting device for lifting the conveying device 7 is further provided on the first roller conveyor. It should be noted that the number of the conveying devices 7 is several, and their conveying directions are consistent with that of the third roller conveyor 3, and they are all arranged along the main direction of material conveying. And these conveying devices 7 are located on the side of the third roller conveyor 3 facing the first roller conveyor 1 and are respectively installed at the gaps between two adjacent rollers on the first roller conveyor 1. The lifting device equipped on the first roller conveyor 1 is used to drive the conveying device 7 to perform lifting motion. When it is necessary to transfer the material from the first roller conveyor 1 to the third roller conveyor 3, the lifting device raises the conveying device 7 so that its conveying surface is higher than the top of the rollers of the first roller conveyor 1. At this time, the material can smoothly transition from the first roller conveyor 1 to the conveying device 7 and then be continuously conveyed to the third roller conveyor 3 by the conveying device 7; when the material transfer is not required, the lifting device lowers the conveying device 7 so that its conveying surface is lower than the top of the rollers of the first roller conveyor 1 to avoid affecting the normal conveying operation of the first roller conveyor 1. The beneficial effect of this design is that: by arranging the liftable conveying device 7 at the roller gaps of the first roller conveyor 1, the spatial layout of the equipment is cleverly utilized to achieve efficient connection between the two conveyors and avoid problems such as material jamming or dropping that may be caused by traditional transfer methods; the design of the lifting device enables the conveying device 7 to rise and work when needed and lower and hide when not needed, without affecting the original function of the first roller conveyor 1, improving the space utilization rate and flexibility of the equipment.

[0037] As Figures 8-10As shown, in this embodiment, each conveying device 7 is installed on the support 31. The bottoms of each of the supports 31 are connected by a connecting plate 29. One end of the connecting plate 29 close to the third roller conveyor 3 is hinged to the frame 28 of the first roller conveyor 1. The lifting device rotates the connecting plate 29 to achieve the lifting of the conveying device 7. It should be noted that each conveying device 7 is fixedly installed through the support 31. The bottoms of the supports 31 are interconnected by means of the connecting plate 29. One end of the connecting plate 29 close to the third roller conveyor 3 forms a hinge structure with the frame 28 of the first roller conveyor 1. The lifting device rotates the connecting plate 29 around the hinge point to achieve the lifting action of the conveying device 7. When the lifting device applies a driving force, the connecting plate 29 rotates upward around the hinge point, driving each support 31 and the conveying device 7 installed thereon to rise synchronously, so that the conveying surface of the conveying device 7 is higher than the top of the rollers of the first roller conveyor 1, thereby receiving and conveying materials. When the lifting device acts in the reverse direction, the connecting plate 29 rotates downward around the hinge point, and the conveying device 7 descends accordingly, and the conveying surface is lower than the top of the rollers, avoiding interfering with the normal operation of the first roller conveyor 1. Through the linkage design of the hinge and the connecting plate 29, this structure converts the driving force of the lifting device into the rotational lifting movement of the conveying device 7, effectively reducing the driving energy consumption by using the lever principle of the hinge point. At the same time, it ensures the synchronous action of multiple conveying devices 7, realizes the smooth transition of materials between different conveyors, improves the space utilization rate and operation reliability of the equipment, and has a simple and compact structure, which is convenient for maintenance and operation.

[0038] As Figures 8-10As shown, in this embodiment, the lifting device includes a cam 30, which is rotatably connected to the frame 28 via a rotating shaft 32. The cam 30 contacts the bottom of the connecting plate 29. The rotating shaft 32 is driven by a motor mounted on the frame 28. It should be noted that the cam 30 in the lifting device is rotatably connected to the frame 28 via the rotating shaft 32. When the motor drives the rotating shaft 32 to rotate, the cam 30 rotates synchronously. Due to the profile of the cam 30, when it contacts the bottom of the connecting plate 29, the profile of the cam 30 changes its contact position with the connecting plate 29 as the rotation angle changes, thereby driving the connecting plate 29 to rotate about its hinge point with the frame 28. When the distal end of the cam 30 gradually contacts the connecting plate 29, the connecting plate 29 is lifted upward, driving the conveyor 7 to its operating position. When the proximal end of the cam 30 contacts the connecting plate 29, the connecting plate 29 falls back under the action of gravity or a return spring, causing the conveyor 7 to descend to its hidden position. This design converts the circular motion into the swinging of the connecting plate 29 by driving the cam 30 with a motor, thereby realizing the lifting and lowering of the conveying device 7. The structure is simple and compact, and the contour curve of the cam 30 can be used to accurately control the lifting stroke and the stop position. The motor can flexibly adjust the working state of the conveying device 7 through forward and reverse or intermittent driving to meet the requirements of different working conditions. At the same time, the cam 30 mechanism has a self-locking function, which can maintain the current position of the conveying device 7 when the power is off or the drive stops, thereby improving the stability and safety of the equipment operation.

[0039] In this embodiment, the conveying device 7 is a belt conveyor.

[0040] The working principle of the present invention is: The storage box 4 is conveyed from the second roller conveyor 2 perpendicular to the first roller conveyor 1 to the entrance of the first roller conveyor 1. After the staff places parts into the storage box 4 beside it, the first roller conveyor 1 starts and conveys the storage box 4 along the main path to the designated position of the conveying device 7 installed at the adjacent roller gap. At this time, the lifting device (such as the cam 30 mechanism) drives the connecting plate 29 to rotate around the hinge point, driving the conveying device 7 to rise, making its conveying surface higher than the top of the rollers of the first roller conveyor 1, and laterally transferring the storage box 4 to the perpendicular third roller conveyor 3. The third roller conveyor 3 continues to convey it in the direction of the mobile vehicle 5 after receiving it; The mobile vehicle 5 travels to the end of the third roller conveyor 3 for docking through the bottom drive mechanism. The second electric slide rail 14 on it vertically lifts along the first guide rail 10, aligning the supporting plate 12 on the bottom support 18 with the third roller conveyor 3. The supporting plate 12 rotates parallel to the conveying direction of the third roller conveyor 3 through the rotation of the first motor. The push plate 16 is driven by the second motor to rotate to a vertical state and laterally moves to the rear of the storage box 4 through the second electric slide rail 14 (at this time, the vertical plate 33 is squeezed by the second electric slide rail 14 and moves downward along the first guiding surface 19, overcoming the elastic force of the first spring 26 to release the limit on the storage box 4, and the wedge block 24 on the mounting frame 17 moves downward with the vertical plate 33, and its second guiding surface 25 disengages from the horizontal support of the guiding rod 22. The guiding rod 22 drives the limiting rod 20 to retract under the elastic force of the second spring 23, pushing the storage box 4 to the center), the push plate 16 rotates to a horizontal state to clamp the rear side of the box body, and the second electric slide rail 14 moves in the reverse direction to pull the storage box 4 to the supporting plate 12; Subsequently, the bottom support 18 is lifted to the height corresponding to the support plate 9, the supporting plate 12 rotates 180° to align with the support plate 9, the push plate 16 rotates to release the limit, and the second electric slide rail 14 drives the clamping plate 15 to push the storage box 4 to the support plate 9. After the mobile vehicle 5 is fully loaded, it moves to one side of the storage rack and repeats similar actions. Through the clamping of the push plate 16, the rotation of the supporting plate 12, and the pushing of the clamping plate 15, the storage box 4 on the support plate 9 is accurately pushed into the corresponding working position of the storage rack according to the instructions of the control system.

[0041] Embodiment 6 This embodiment provides an intelligent warehousing and outbound method, including: Step 1: The storage box 4 is conveyed from the second roller conveyor 2 perpendicular to the first roller conveyor 1 to the first roller conveyor 1. The staff places the corresponding parts into the storage box 4 on one side of the first roller conveyor 1, and the first roller conveyor 1 starts to move the storage box 4 to the designated position; Step 2: The conveying device 7 on the first roller conveyor 1 laterally transfers the storage box 4 to the perpendicular third roller conveyor 3, and the third roller conveyor 3 continues to convey the storage box 4 after receiving it; Step 3: The mobile vehicle 5 travels to the side of the third roller conveyor 3, and the transfer device 6 transfers the storage box 4 on the third roller conveyor 3 to the support plate 9 of the mobile vehicle 5; Step 4: The mobile vehicle 5 moves to one side of the storage rack, and the transfer device 6 transports the storage boxes 4 on the support plate 9 to the corresponding storage stations of the storage rack one by one; Among them, the control system coordinates and controls the start-stop, speed and actions of each device to ensure the automatic connection of the feeding, transfer and storage processes of the storage box 4.
