Description

Technical Field

[0001] This invention relates to the field of sheet material feeding equipment, and in particular to a novel automated material storage device. Background Technology

[0002] With the widespread application of laser cutting technology in the metal processing industry, the efficiency and precision requirements for sheet metal cutting are constantly increasing. As a core supporting equipment for laser cutting machines, automated material storage directly affects the operating efficiency of the entire production line.

[0003] Currently, most automated material storage systems on the market adopt a single-station design, meaning that one system can typically only supply material to one laser cutting machine. When a company has multiple laser cutting machines, each machine needs its own independent material storage unit. This not only significantly increases equipment procurement costs but also occupies a large amount of workshop production space, resulting in a waste of land resources.

[0004] Moreover, in existing technologies, although some material storage bins have achieved automated feeding, the unloading process still relies on manual operation. The speed of manual unloading is difficult to match the processing rhythm of the laser cutting machine, often resulting in the cutting machine waiting for unloading, which seriously restricts the improvement of production efficiency.

[0005] Some material storage facilities use a single-layer feeding method. When the previous stack of boards is used up, it is necessary to replenish the material, which makes it difficult to achieve uninterrupted feeding and further reduces the effective working time of the equipment.

[0006] In summary, existing automated material storage systems suffer from limited supply capacity, asynchronous loading and unloading, and poor feeding continuity, making it difficult to meet the needs of modern metal processing enterprises for multi-machine collaboration and efficient continuous production.

Power racks are installed on the opposite faces of the two guide rods. A fourth geared motor with a fourth dual-axis reduction mechanism is installed in the middle of the crossbeam. The two output shafts of the fourth dual-axis reduction mechanism rotate through the two displacement plates, and displacement gears are coaxially installed at the ends of the two output shafts.

One end of the coil spring is connected to the locking pin, and the other end is connected to the lifting block. An electromagnet is installed on the side wall of the lifting block away from the helical rack. When the electromagnet is energized, it attracts the bottom of the locking pin. In this state, the locking pin does not contact the helical rack. When the electromagnet is de-energized, the coil spring pushes the bottom of the locking pin to rotate and locks the corresponding part of the helical rack teeth.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. It enables multi-machine collaborative operation. A single material storage unit can provide supporting services for multiple laser cutting machines at the same time, eliminating the need to configure a separate material storage unit for each cutting machine, which greatly reduces equipment procurement costs and reduces the occupation of workshop production space.

[0025] 2. It realizes fully automated loading and unloading operations, replacing the manual loading process. The loading and unloading actions can be precisely matched with the processing rhythm of the laser cutting machine, avoiding the situation where the cutting machine waits for loading, and effectively improving production efficiency.

[0026] 3. The alternating dual-station feeding design allows two feeding trolleys to alternately complete the receiving and feeding operations. The replenishment process does not require machine downtime, achieving uninterrupted and continuous supply of sheet materials and improving the effective working time of the equipment.

Detailed Implementation

[0044] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0045] like Figures 1 to 16 As shown

[0046] Example 1:

[0047] The novel automated material storage device of the present invention includes:

[0048] The material tower 1 has several slides evenly distributed longitudinally. The slides are used to store material trays 2, and the material trays 2 can be pulled out and placed on the slides. The bottom of the material tower 1 is provided with an alternating dual-station feeding mechanism. The receiving part of the feeding mechanism is located at the bottom of the material tower 1 and directly below the material trays 2, while its feeding part extends from the discharge side of the material tower 1.

[0049] An automatic pick-and-place mechanism is installed on the feeding side of the material tower 1. It is used to replenish the material tower 1 and transfer the material rack 2 on which the plate is placed on the material tower 1 to the feeding mechanism.

[0050] The main frame 3 is equipped with an automatic feeding mechanism and an automatic unloading mechanism. The feeding side of the main frame 3 is installed close to the feeding side of the material tower 1, and the feeding part of the feeding mechanism extends into the feeding area of ​​the main frame 3. The other side of the main frame 3 opposite to the feeding area is equipped with an unloading area. An alternating dual-station feeding mechanism 4 is provided in the unloading area. The top of the main frame 3 is equipped with a track 5 for the movement of the automatic feeding mechanism and the automatic unloading mechanism, and the automatic feeding mechanism is located on the side closer to the material tower 1.

[0051] The main frame 3 has several working areas in the middle, each working area corresponds to a laser cutting device 6, and the material handling part of the laser cutting device 6 extends into the corresponding working area.

[0052] The side of the material tower 1 is provided with a control box mechanism 7, which is used to provide working power to the material silo and send control signals to each electrical component of the material silo to realize the start-up, shutdown, operation and action control of the material silo.

[0053] Preferably, the automatic pick-and-place mechanism includes a gantry frame 8 and a bracket 9. Two columns of the gantry frame 8 are installed on the factory ground, and both columns are connected to the feeding side of the material tower 1 via several connecting rods. Each column has a main sprocket 10 at its top and bottom on the side wall of the automatic pick-and-place mechanism. A main chain 11 sequentially meshes with and passes around the two main sprockets 10. A first servo motor 12 is located at the center of the bottom of the gantry frame 8. The output end of the first servo motor 12 is connected to a first dual-axis reduction mechanism. The two output shafts of the first dual-axis reduction mechanism are respectively connected to the bottom of the two columns. The two main sprockets 10 are coaxially connected. Both ends of the bracket 9 are provided with pick-and-place slide plates 13. Lifting blocks 14 are installed at the middle of the outer ends of the two pick-and-place slide plates 13. Both ends of the main chain 11 are connected to the lifting blocks 14 on the same side. Limiting components are provided on the lifting blocks 14. Both lifting blocks 14 are slidably engaged with the opposite sides of the two columns through the limiting components. Each pick-and-place slide plate 13 has a pick-and-place slide rail 15 at its top. A sliding block 16 is slidably installed on the pick-and-place slide rail 15. A pick-and-place shaft 17 is provided on the side of the sliding block 16 facing the material tower 1. The material rack 2 faces the door. Hooks 18 are provided on both the left and right sides of one end of the frame 8. When the bracket 9 is in the state of picking up and placing the material tray 2, the two hooks 18 of the material tray 2 are hooked on the two pick-up and place shafts 17 of the two sliding blocks 16. The inner top of the two pick-up and place slide plates 13 are provided with power grooves. Each power groove has a transmission sprocket 19 installed at both ends. Two guide sprockets 20 and a power sprocket 21 are installed in the middle of the power groove. The power sprocket 21 is located in the lower middle position of the two guide sprockets 20. The two transmission sprockets 19, the two guide sprockets 20 and the power sprocket 21 on the same side are adapted to mesh with a pick-up and place closed-loop chain 2. 2. The side wall of the sliding block 16 is connected to the pick-and-place closed-loop chain 22 via a connecting block. A second geared motor 23 with a second dual-axis reduction mechanism is installed at the bottom center of the bracket 9. The two output ends of the second dual-axis reduction mechanism are coaxially connected to the two power sprockets 21 of the two pick-and-place slide plates 13. Both the bracket 9 and the material tray 2 are designed with a hollow structure. Several lifting rods 24 are provided at the bottom of the gantry frame 8. When the bracket 9, which holds the material tray 2, descends to the lowest position, several lifting rods 24 pass through the bracket 9 and the material tray 2 and extend to the upper side of the material tray 2 to support the plate material transported by the forklift.

[0054] More preferably, the limiting component includes a plurality of guide rollers 62, which are evenly distributed on the upper and lower sides of the lifting block 14, and the plurality of guide rollers 62 on the opposite side hold the corresponding column, and the plurality of guide rollers 62 in the middle of the lifting block 14 cooperate with the surface of the column facing the lifting block 14 for limiting.

[0055] Preferably, a helical rack 63 with upward-sloping teeth is installed on the surface of the column facing the corresponding side lifting block 14. Several guide rollers 62 in the middle of the lifting block 14 are in close contact with the side wall of the helical rack 63. A locking pin 64 is rotatably installed on the side wall of the lifting block 14. A coil spring 65 is sleeved on the rotating shaft of the lifting block 14 on which the locking pin 64 is installed. One end of the coil spring 65 is connected to the locking pin 64, and the other end is connected to the lifting block 14. An electromagnet 66 is provided on the side wall of the lifting block 14 away from the helical rack 63. When the electromagnet 66 is energized, it attracts the bottom of the locking pin 64. In this state, the locking pin 64 and the helical rack 63 are not in contact. When the electromagnet 66 is de-energized, the coil spring 65 pushes the bottom of the locking pin 64 to rotate and locks the teeth of the helical rack 63 at the corresponding part of the locking pin 64.

[0056] Preferably, the feeding mechanism 4 of the alternating dual-station type is provided with two feeding plates 37, and the top of each feeding plate 37 is provided with several evenly distributed pads 38. The top of the material handling section of the laser cutting equipment 6 is also provided with several evenly distributed pads 38. The several evenly distributed pads 38 are used to support the steel plate to adapt to the automatic unloading mechanism.

[0057] In this embodiment,

[0058] The control box mechanism 7 is installed on the side of the material tower 1 in a wall-mounted or floor-standing cabinet with a protection level of not less than IP54, which is suitable for dusty and humid workshop environments. Its internal components include, but are not limited to, a power module, a main controller, a PLC as the core control unit, a servo drive module, an input / output (I / O) module, a communication module, a safety protection module, and a human-machine interaction unit. The control box mechanism 7 coordinates the action sequence of various components of the material warehouse.

[0059] During the replenishment operation, the bracket 9 moves the empty material paddle 2 to the top of the bracket 9 through the cooperation of the pick-up and put-down shaft 17 of the sliding block 16 and the two hooks 18 of the empty material paddle 2.

[0060] Then, the first servo motor 12 is controlled to drive the main sprocket 10 to rotate, and the main chain 11 pulls the lifting block 14 and the bracket 9 down to the lowest position. At this time, the lifting rod 24 at the bottom of the gantry frame 8 passes through the hollow bracket 9 and the material tray 2 and extends above the upper surface of the material tray 2.

[0061] The forklift places the stacked boards directly onto the lifting lever 24. After the forklift moves away, the first servo motor 12 rotates in the opposite direction, causing the bracket 9 to rise slowly.

[0062] During the upward movement of the bracket 9, the material paddle 2 first contacts the bottom of the board and lifts the entire stack of boards from the lifting rod 24. At this time, the hook 18 of the material paddle 2 remains in the hanging state with the pick-up and put-down shaft 17.

[0063] After the bracket 9 continues to rise to the height of the slide corresponding to the material tower 1, it stops. The second reduction motor 23 starts and drives the power sprocket 21 to rotate through the second dual-shaft reduction mechanism, thereby driving the pick-and-place closed-loop chain 22 to operate.

[0064] The pick-and-place closed-loop chain 22 drives the sliding block 16 to move along the pick-and-place slide rail 15 toward the material tower 1 through the connecting block. The sliding block 16 pushes the material paddle 2 to slide horizontally through the cooperation of the pick-and-place shaft 17 and the hook 18 until the material paddle 2 is completely inserted into the slide frame of the corresponding height.

[0065] Then the first servo motor 12 drives the bracket 9 to descend a small distance of 1-2cm, so that the pick-up and put-out shaft 17 naturally disengages from the hook 18 of the material tray 2. The second reduction motor 23 rotates in the opposite direction, driving the sliding block 16 to return to the initial position, completing one material replenishment operation.

[0066] By repeating the above operation process, the feeding of material tower 1 can be completed quickly.

[0067] During material handling, the bracket 9 rises to the height of the corresponding carriage, and the sliding block 16 moves towards the material tower 1, causing the pick-and-place shaft 17 to extend below the hook 18 of the material tray 2. The bracket 9 rises a small distance, allowing the pick-and-place shaft 17 to hook the hook 18. Then, the sliding block 16 moves in the opposite direction, pulling the material tray 2 out of the carriage onto the bracket 9. The bracket 9 descends to the corresponding position of the material receiving station of the feeding mechanism at the bottom of the material tower 1. Then, the two sliding blocks 16, through the cooperation of the two pick-and-place shafts 17 and the two hooks 18, push the material tray 2 containing the plate to slide to the receiving part of the feeding mechanism. Then, the bracket 9 descends a small distance again, placing the material tray 2 on the feeding mechanism. The pick-and-place shaft 17 disengages from the hook 18, and the sliding block 16 returns to its original position.

[0068] Multiple sets of guide rollers 62 on the lifting block 14 hold the column from three directions, ensuring smooth and stable operation of the bracket 9 during lifting. The anti-fall structure, which cooperates with the rack and pin 64, ensures that the electromagnet 66 is energized and holds the pin 64 during normal operation of the equipment, without affecting the normal lifting of the bracket 9. In case of power failure or chain breakage, the electromagnet 66 is de-energized, and the coil spring 65 pushes the pin 64 into the teeth of the rack and pin 63, instantly locking the position of the lifting block 14 to prevent the bracket 9 and the plate from falling, thus ensuring the safety of the equipment and personnel.

[0069] After the feeding mechanism delivers the material tray 2 carrying the sheet metal to the loading area of ​​the main frame 3, the automatic feeding mechanism moves above the loading area, picks up a single sheet metal, and then moves above the corresponding working area of ​​the laser cutting machine, placing the sheet metal on the picking and placing section of the laser cutting machine. After the laser cutting machine completes the cutting operation, the automatic unloading mechanism moves above the working area, lifts up the cut finished product and waste together, and moves it above the delivery plate 37 in the unloading area, placing the finished product and waste on the delivery plate 37. The two delivery plates 37 of the dual-station delivery mechanism 4 work alternately. While one delivery plate 37 is transporting finished products and waste out, the other delivery plate 37 is waiting to receive materials in the unloading area, ensuring continuous unloading operations. The alternating dual-station operation principle of the delivery mechanism 4 is consistent with the alternating dual-station operation principle of the feeding mechanism. Other reasonable equivalent solutions can also be selected and used.

[0070] Example 2:

[0071] As a preferred embodiment, the frame of the receiving part of the feeding mechanism is connected to the bottom inner wall of the material tower 1. The alternating double-station feeding mechanism is configured as a longitudinally arranged double-station, with guide rails on both the left and right sides of each station. Each station is equipped with a feeding trolley 25, and at least two pairs of wheelsets 26 are evenly distributed on the bottom of the feeding trolley 25. The two wheels of each wheelet 26 are respectively connected to the two guide rails on both sides in a rolling engagement. Gearboxes 27 are provided on both the left and right sides of the end of the feeding part of the feeding mechanism. The frame at the end of the feeding part is... The unit is equipped with a third geared motor 28 with a third dual-axis reduction mechanism. The two output shafts of the third dual-axis reduction mechanism are respectively rotatably inserted into the gearboxes 27 on both sides. The output shafts of the third dual-axis reduction mechanism located in the gearboxes 27 are coaxially mounted with a power gear 29. The upper side of the power gear 29 meshes with a transmission gear 30. The two output shafts of the third dual-axis reduction mechanism are coaxially provided with lower feed sprockets 31 near the two gearboxes 27. The mounting shafts of the two transmission gears 30 extend to the opposite sides of the two gearboxes 27, and the two transmission gears 30 are respectively connected to the gearboxes 27. An intermediate sprocket 32 ​​is coaxially mounted on the end of the mounting shaft of the moving gear 30. An upper feeding sprocket 33 and a steering sprocket are rotatably mounted on the top of the opposite surfaces of the two gearboxes 27. The lower feeding sprocket 31 and the upper feeding sprocket 33 are respectively adapted to the height of the lower and upper working positions of the feeding mechanism. A support sprocket 34 is rotatably mounted in the middle of the opposite surfaces of the two guide rails of the receiving part of each working position. A closed-loop feeding chain 35 is provided on both sides of each working position. The closed-loop feeding chain 35 of the lower working position is adapted to mesh with the lower feeding sprocket 31 and the support sprocket 34 on the corresponding side. The feeding closed-loop chain 35 of the upper station is adapted and meshed with the corresponding middle sprocket 32, upper feeding sprocket 33, steering sprocket and support sprocket 34. The feeding closed-loop chains 35 on the left and right sides of each station are respectively connected to the bottom left and right of the corresponding feeding trolley 25. The two feeding trolleys 25 of the double station take turns receiving and feeding materials. When the feeding mechanism is in working state, the material paddle 2 can be slidably placed on the top of the feeding trolley 25. The material paddle 2 is equipped with several auxiliary rollers, and several protective rods are provided on the top of the material paddle 2 except for the material picking and placing side.

[0072] In this embodiment,

[0073] The feeding mechanism adopts a vertically arranged dual-station design, with two feeding trolleys operating independently.

[0074] In the initial state, the feeding trolley 25 of the upper station is parked at the receiving section waiting to receive materials, while the feeding trolley 25 of the lower station is parked at the feeding section on standby. When the automatic pick-and-place mechanism places the material tray 2 carrying the sheet material onto the feeding trolley 25 of the upper station, the third reduction motor 28 starts and drives the power gear 29 to rotate through the third dual-shaft reduction mechanism. At this time, the lower feeding sprocket 31 and the corresponding support sprocket 34 drive the lower feeding closed-loop chain 35 to rotate. Simultaneously, the power gear 29 drives the transmission gear 30 to rotate, and the transmission gear 30 drives the intermediate sprocket 32 ​​to rotate through the mounting shaft. The intermediate sprocket 32 ​​drives the upper feeding sprocket 33 to rotate, thereby driving the upper feeding closed-loop chain 35 of the upper station to rotate and pulling the upper feeding trolley 25 to move along the guide rail towards the feeding section.

[0075] As the upper feeding trolley 25 moves towards the feeding section, the lower feeding trolley 25, pulled by the lower feeding closed-loop chain 35, moves towards the receiving section. When the upper feeding trolley 25 reaches the feeding section and delivers the material tray 2 to the automatic feeding mechanism, the lower feeding trolley 25 arrives at the receiving section to receive the next material tray 2. Then, the third reduction motor 28 rotates in the opposite direction, the upper feeding trolley 25 returns to the receiving section, and the lower feeding trolley 25 moves towards the feeding section, thus repeating the cycle. The two feeding trolleys 25 alternately complete the receiving and feeding operations, with the feeding process of the previous material tray 2 and the receiving process of the next material tray 2 proceeding synchronously without waiting.

[0076] The auxiliary rollers installed at the bottom of the material paddle 2 reduce the friction when the material paddle 2 slides on the feeding trolley 25, making the picking and placing of the material paddle 2 smoother. The protective bar set at the top of the material paddle 2 forms a protective barrier around the three sides of the material to prevent the material from shifting or slipping during transportation.

[0077] Example 3:

[0078] As a preferred embodiment, both the automatic feeding mechanism and the automatic unloading mechanism are equipped with an automatic displacement mechanism.

The two displacement gears 45 mesh with the two power racks 43 respectively.

[0080] More preferably, the lifting mechanism includes a limiting frame 46 and a telescopic column 47. The limiting frame 46 is longitudinally mounted on the crossbeam 39. At least two longitudinal guide rails 48 are installed on the inner side wall of the limiting frame 46. The telescopic column 47 passes through the limiting frame 46, and the side wall of the telescopic column 47 is provided with guide sliders that match the number of guide rails 48. The guide sliders are slidably engaged with the guide rails 48. The bottom end of the telescopic column 47 is provided with an installation part 49 that is connected to an automatic feeding mechanism or an automatic unloading mechanism. An electric telescopic rod 50 is installed on the inner side wall of the limiting frame 46, and the telescopic end of the electric telescopic rod 50 is connected to the installation part 49.

[0081] Preferably, the forklift unloading robot assembly includes a support frame 51, the top center of which is connected to the mounting component 49. Control frames 52 are provided at each of the four corners of the top of the support frame 51. Positioning rods 53 are provided at both ends of the support frame 51 along the guide rail 48. Each positioning rod 53 has several through holes evenly distributed along the guide rail 48, and fork rods 54 extend and retract through each through hole. A synchronization rod 55 is provided on the side away from the support frame 51. The ends of the fork rods 54 away from the positioning rods 53 are connected to the synchronization rod 55. Control slide rods 56 are installed on the top of both sides of the synchronization rod 55. Control slide rails 57 are provided at the top of the control slide rods 56. A control slider 58 with a groove is provided on the outer side of the bottom end of each control frame 52. The two control slide rails 57 of the synchronization rod 55 are respectively connected to the two control slide rails 58 on the same side. The control slider 58 of the control frame 52 is slidably mounted. Control sprockets 59 are rotatably mounted on the front and rear sides of the outer side walls at both ends of the support frame 51. Two control sprockets 59 on the same side are meshed with a closed-loop control chain. Connectors 60 are provided on the opposite side of the two control slides 56 on the synchronizing rod 55 away from the synchronizing rod 55. The two connectors 60 of the two control slides 56 on one side of the synchronizing rod 55 are respectively connected to the upper chain of the two closed-loop control chains, and the two connectors 60 on the other side are respectively connected to the lower chain of the two closed-loop control chains. A fifth geared motor 61 with a fifth dual-axis reduction mechanism is provided in the middle of one side of the support frame 51. The two output shafts of the fifth dual-axis reduction mechanism rotatably pass through the left and right side walls of the support frame 51, and the two output shafts are coaxially connected to the corresponding two control sprockets 59.

[0082] In this embodiment,

[0083] During automatic feeding operation, the fourth reduction motor 44 starts and drives the displacement gear 45 to rotate through the fourth double-shaft reduction mechanism. The displacement gear 45 meshes with the power rack 43 on the guide rod 41, driving the crossbeam 39 to move laterally along the track 5 at the top of the main frame 3, so that the automatic feeding mechanism moves to directly above the material tray 2 in the feeding area.

[0084] The electric telescopic rod 50 pushes the telescopic column 47 down along the guide rail 48, and the suction cup loading assembly 36 contacts the upper surface of the board, activating the vacuum suction cup to hold the single board. After the electric telescopic rod 50 drives the telescopic column 47 to the set height, the automatic displacement mechanism drives the automatic loading mechanism to move directly above the corresponding working area of ​​the laser cutting machine. The electric telescopic rod 50 pushes the telescopic column 47 down again, placing the board smoothly on the pad rod 38 of the laser cutting machine's loading and unloading section. The vacuum suction cup releases the board, the lifting mechanism resets, and one loading operation is completed.

[0085] During automatic unloading, the automatic displacement mechanism moves the automatic unloading mechanism to directly above the working area of ​​the laser cutting machine after cutting. The electric telescopic rod 50 pushes the telescopic column 47 down, so that the height of the fork 54 of the fork unloading robot assembly is lower than the upper surface of the pad 38. The fifth reduction motor 61 starts, driving the control sprocket 59 to rotate through the fifth dual-axis reduction mechanism, and the control sprocket 59 drives the closed-loop control chain to operate. Since the connecting parts 60 of the two synchronous rods 55 are respectively connected to the upper and lower sides of the closed-loop control chain, when the closed-loop control chain rotates, the synchronous rods 55 on both sides will drive the fork 54 to extend synchronously in opposite directions, that is, several forks 54 on both sides move relatively close and insert into the gap of the pad 38 under the plate. After the fork 54 is fully extended and the through hole of the positioning rod 53 is reached, the electric telescopic rod 50 drives the telescopic column 47 to rise, and the fork 54 lifts the finished product and waste material together from the pad 38. The automatic displacement mechanism drives the automatic unloading mechanism to move directly above the delivery plate 37 in the unloading area. The electric telescopic rod 50 drives the telescopic column 47 to descend, and the fifth reduction motor 61 rotates in the opposite direction, driving the fork 54 to retract synchronously, placing the finished product and waste material smoothly on the pad rod 38 of the delivery plate 37. The lifting mechanism resets, completing one unloading operation.

[0086] The automatic displacement mechanism employs a rack and pinion drive, ensuring high transmission precision and smooth operation, enabling accurate positioning of various working areas and loading / unloading zones. The lifting mechanism utilizes an electric telescopic rod 50 for rapid response and adjustable lifting stroke, accommodating loading and unloading needs of materials of varying thicknesses. The forklift unloading robot features a dual synchronous rod 55 design, with both forks 54 extending and retracting synchronously, ensuring even force distribution and stable lifting of materials and waste of different sizes and weights.

[0087] Each servo motor of the present invention is equipped with a multi-turn or single-turn absolute encoder at its output end, and the auxiliary limit and status detection of each displacement component are accomplished by an inductive proximity switch or a diffuse reflection / through-beam photoelectric sensor, which is used for overtravel protection, position verification, and material pickup and plate arrival detection.

[0088] The working principle of this invention is as follows:

[0089] This novel automated material storage system uses a control box mechanism 7 as its core control unit to coordinate the operation sequence of all components. First, the automatic pick-and-place mechanism replenishes the material tower 1, storing stacked sheet metal trays 2 in an orderly fashion on the multi-layered carriages of the tower 1. When feeding is needed, the automatic pick-and-place mechanism transfers the trays 2 to the alternating dual-station feeding mechanism at the bottom of the tower 1. Two feeding trolleys 25 alternately deliver the trays 2 to the loading area of ​​the main frame 3. The automatic loading mechanism picks up the sheet metal from the trays 2 and delivers it to the corresponding laser cutting machine's working area for cutting. After cutting, the automatic unloading mechanism removes the finished product and waste material and delivers them to the dual-station delivery mechanism 4 in the unloading area, where the delivery mechanism 4 alternately delivers them. The entire process achieves fully automated continuous operation. A single set of equipment can simultaneously provide support for multiple laser cutting machines, effectively solving the problems of limited supply capacity, asynchronous loading and unloading, and poor feeding continuity in existing technologies.

[0090] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
