Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a profile feeding device, processing equipment, and feeding method. Background Technology

[0002] Before processing, profiles are typically stacked in multiple layers in a material frame, separated by spacers / pallets. The loading operation requires processes such as feeding the material frame, separating the profiles from the spacers, adjusting their posture, and conveying them neatly. Existing technology, patent CN119660253A, discloses a profile loading machine, which has the following defects: Poor flipping posture and synchronization: The profile is conveyed to the clamping part, refer to its Figure 9 and Figure 10 The clamping component does not perform a clamping action. It relies on the hanging plate to maintain contact with the profile during the profile flipping and falling process to ensure the profile's posture when flipped onto the second conveyor belt. This structure is complex. In the actual flipping process, since the profile is not directly clamped and fixed, it is impossible to accurately control which side of the profile the hanging plate contacts, and its flipping posture cannot be guaranteed. In addition, the profile posture flipping adopts a simple transmission with a single-axis independent drive, and multiple flipping mechanisms are difficult to operate synchronously, resulting in inconsistent profile flipping angles and disordered postures, which affects subsequent processing and positioning.

[0003] The prior art patent CN119897375A discloses an automatic aluminum profile production line and its control method. The aluminum profile feeding direction is the same as that of the subsequent processing equipment, which has the following defects: the overall length of the equipment is extremely long, the production line occupies a large area and the plant utilization rate is low; the feeding stroke is long, the single feeding time is long and the cycle is slow; it can only feed one profile at a time along the length direction, and it cannot feed in groups or rows; the equipment is connected in series, resulting in poor expandability and inconvenient maintenance.

[0004] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a profile feeding device, processing equipment and feeding method. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a profile feeding device, processing equipment and feeding method, which aims to solve the problems of discontinuous feeding, inaccurate picking and positioning, asynchronous flipping and poor connection between flipping and transfer in the process of profile processing and feeding.

[0006] To solve the above-mentioned technical problems, one technical solution adopted by the present invention is: to provide a profile feeding device, comprising: The conveying module conveys profiles along the X direction, including several belt conveyor lines spaced apart along the Y direction.

It recovers the empty material frame that has been filled at the first material position, docks and transports the full material frame to the first material position, and transfers the empty material frame at the original first material position to the second material position. The conveying mechanism has a working range covering the first material position and the second material position. It is used to pick up a set of pallets and a layer of profiles on the pallets from the material frame at the first material position, and then transport them to the second material position, place the layer of profiles on the conveying module, and put the pallets into the pallet recycling frame at the second material position.

[0010] Preferably, the transfer mechanism includes a frame, an X-axis servo module mounted on the frame, a transfer frame driven by the X-axis servo module to move horizontally, several sets of transfer gripper cylinders mounted on the transfer frame for gripping profiles, a Z-axis servo module mounted on the frame, a lifting frame driven by the Z-axis servo module to move vertically, at least two pen-shaped cylinders horizontally mounted on the lifting frame, and a transfer platform driven by the pen-shaped cylinders to extend and receive profiles; the transfer platform is provided with several positioning grooves for placing and positioning profiles.

[0011] Preferably, the output mechanism includes several sets of conveying components synchronously connected by sprocket assemblies, with clearance reserved between adjacent sets of conveying components for the transfer platform of the transfer mechanism to perform lifting and lowering movements, and the conveying direction of the conveying components being horizontal and perpendicular to the conveying direction of the conveying module; the conveying components include a rotatably mounted drive shaft, a conveying roller mounted on the drive shaft, and limiting baffles mounted on the drive shafts on both sides of the conveying roller.

[0012] Preferably, the dual-carrying trolley includes two parallel ground rail assemblies, a traveling mechanism that is rolled on the two ground rail assemblies and travels along their arrangement direction, and two carrying positions distributed on the traveling mechanism, each carrying position being provided with a feeding mechanism.

[0013] Preferably, the conveying mechanism includes a gantry frame, a drive mechanism mounted on the gantry frame, a movable frame disposed at the movable end of the drive mechanism, a lifting drive component mounted on the movable frame, a lifting support beam driven by the lifting drive component to move up and down, and several sets of material picking modules arranged along the length direction of the lifting support beam. Each material picking module includes two sets of material picking structures arranged opposite each other along the width direction of the lifting support beam. Each material picking structure has a pair of relatively movable material picking grippers and a detection component that can identify the material picking position as the lifting support beam moves. A horizontally extending gripping part for supporting the bottom of the pallet is provided on the opposite surface of the pair of material picking grippers. The bottom surface of the pallet has a material picking positioning groove that cooperates with the gripping part for easy gripping. The detection component includes a sensing plate movably mounted on the lifting support beam via a Z-axis slide rail, a sensing element mounted on the sensing plate, and a sensor mounted on the lifting support beam that senses the sensing element. The lifting support beam stops descending when the sensor senses the sensing element.

[0014] A profile processing equipment includes a profile cutting machine, a profile punching machine, an inspection machine, and a profile stacking machine arranged sequentially along the X direction, and a profile feeding device that feeds profiles to the profile cutting machine along the Y direction.

[0015] A feeding method for a profile feeding device includes the following steps: S1. The upper layer profiles stacked one by one are conveyed along the conveying direction of the conveying module until the blocking component of the conveying module abuts against the inner reinforcing rib of the outermost profile. S2. The flipping mechanism simultaneously clamps the A side of the profile, preventing the component from rotating and resetting. The flipping mechanism flips, and the B side of the profile, which is perpendicular to the A side of the profile, turns to a horizontal state. S3. Transfer the flipped profiles to the transfer platform in sequence, and position the multiple profiles using the reinforcing ribs D parallel to the B side of the profile as the positioning reference. S4. The transfer platform moves downward in the vertical direction. Multiple profiles move downward and are supported by several sets of conveying components that are alternately set with the transfer platform. The reinforcing ribs D on the profiles fall on the conveying rollers of the conveying components. The rotating conveying rollers output the profiles along the Y direction and connect them with the subsequent processing equipment.

[0016] Preferably, the step of transferring the upper profile to the conveying module in step S1 is as follows: S1-1, The dual-carrying trolley is equipped with two carrying positions. One carrying position recovers the empty material frame that has been taken out of the first material position. The other carrying position transports the material frame filled with profiles to the first material position and transfers the empty material frame to the second material position. S1-2. The conveying mechanism drives several sets of material picking modules to move synchronously. The sliding sensor plate moves down with the material picking module and abuts against the upper tray in the material frame. The picking claws continue to move down with the material picking module until the sensor that moves synchronously with the picking claws senses the sensor plate on the sensor plate. A pair of relatively moving picking claws are guided to quickly insert into the material picking positioning groove on the bottom surface of the tray, and transport a set of trays in the material frame at the first material position and a layer of profiles on the tray to the conveying module. S1-3, The upper profile moves along the conveying direction of the conveying module, and the pallets, which are alternately set with the belt conveyor line, fall into the second material position to retrieve the pallet material frame; S1-4. After the profiles in the material frame at the first material position are removed, one of the bearing positions of the dual-position trolley is connected to the front-end material frame feeding equipment to input the material frame filled with profiles and pallets. S1-5, The material frame at the second material position is filled with pallets. The other load position of the dual-load trolley inputs the material frame filled with pallets and outputs it.

[0017] Compared with the prior art, the beneficial effects of the present invention are: Dual-position material supply: The dual-position trolley design is used in conjunction with the dual-position material supply. One position completes the loading of the full material frame, while the other position simultaneously completes the recycling of the empty material frame and the storage of the pallet. The material supply is uninterrupted, and the equipment utilization rate and material supply efficiency are significantly improved. Precise material picking position identification: Through the cooperation of induction plate, induction sheet and sensor, the position of the upper pallet is automatically detected and the picking height is locked. The picking claw is precisely inserted into the picking positioning slot of the pallet, avoiding gaping and damage to the profile. The success rate and stability of picking are greatly improved. It adapts to changes in stacking height and does not require manual adjustment of picking parameters. Synchronous flipping drive: The transmission shaft is synchronously driven by rack and pinion meshing, which has strong rigidity, no lag or step loss. Multiple sets of rotating disks are linked coaxially, with consistent flipping angles and smooth operation. The profile is directly clamped by two gripper blocks driven by the gripper cylinder, and the profile flipping posture is uniform, which meets the positioning requirements of subsequent processing. The flipping and transfer positioning work together efficiently: the flipping mechanism accurately outputs the profiles, and the transfer platform is positioned based on the reinforcing ribs of the profiles. Multiple profiles are simultaneously aligned and then transferred to the output mechanism. The process is closely connected, with no jamming or misalignment. The entire process is highly automated with minimal human intervention, and production efficiency and product yield are improved simultaneously. The feeding direction is perpendicular to the subsequent processing direction, which greatly shortens the production line length, significantly reduces the vertical footprint, and increases the utilization rate of the factory; the feeding stroke is short, the feeding speed is faster, and the production cycle is improved; it can feed in groups or rows, and convey multiple pieces at one time, which is more efficient; the feeding and processing equipment are arranged vertically, making the layout more compact and flexible.

The transfer mechanism 6 is connected to the flipping mechanism 5 and is equipped with several transfer platforms 68 for positioning and receiving materials. The output mechanism 7 is connected to the transfer mechanism 6, and synchronously receives multiple positioned profiles from the transfer mechanism 6 and transports them to subsequent processing equipment.

[0037] Several layers of profiles 01 are stacked inside the material frame 00. Several support plates 02 are placed horizontally between two adjacent layers of profiles 01 along the length of the profile. The profile 01 includes a parallel A surface and a C surface, as well as a B surface that is perpendicular to the A surface and the C surface. A reinforcing rib D is provided on the side of the B surface of the profile.

[0038] The material frame carrying position 1 includes a docking frame 11 installed on the working ground. The docking frame 11 is provided with two feeding positions, namely the first material position 101 and the second material position 102. The first material position 101 receives a full material frame 00, which comes from the carrying position of the dual-carrying trolley 2. The full material frame 00 here is used for profile feeding. The second material position 102 receives an empty material frame for recycling the pallet 02. The end of the docking frame 11 is equipped with a buffer 12 that contacts and cooperates with the material frame 00 and a through-beam optical fiber 13 for identifying whether the material frame 00 is in place.

[0039] The dual-carrying trolley 2 includes two parallel ground rail assemblies 21, a traveling mechanism 22 that is rolled on the two ground rail assemblies 21 and travels along their arrangement direction, and two carrying positions distributed on the traveling mechanism 22. One carrying position is used to carry a full material frame 00 and transport the full material frame 00 to the first material position 101. The other carrying position carries an empty material frame and transports the empty material frame to the second material position 102. Each carrying position is provided with a feeding mechanism 23. The traveling mechanism 22 includes a traveling frame 221, a driving component 222 that drives the traveling frame 221, and components installed on the traveling frame 221 to prevent the traveling mechanism 22 from deviating from the traveling rail. The limiting wheel 223 is provided with an internal groove 2230 for being snapped onto the ground rail assembly 21. The ground rail assembly 21 includes a ground rail 211, angle steel 212 located on both sides of the ground rail 211, and a sliding contact line moving power supply system 213 for power supply located on the side end of the ground rail 211. A limiting track is formed between the ground rail 211 and the angle steel 212. The protrusions at both ends of the limiting wheel 223 are located within the limiting track. The feeding mechanism 23 includes a feeding frame 231, a plurality of sets of power rollers 232 rotatably mounted on the feeding frame 231, and a power unit 233 that drives the plurality of sets of power rollers 232 to rotate synchronously.

[0040] The conveying module 3 uses a belt conveyor line 31, which is alternately arranged with pallets. It also includes a blocking component 32, which includes a fixed plate 321, a connecting shaft 322 rotatably mounted on the fixed plate 321, a rotating component 323 mounted on the connecting shaft 322, a blocking component 324 mounted on one end of the rotating component 323 and opposite to the profile 01, a blocking cylinder 325 rotatably mounted on the fixed plate 321 at its tail, and a connector 326 mounted on the piston rod of the blocking cylinder 325 and movably connected to the other end of the rotating component 323. When the piston rod of the blocking cylinder 325 extends, it drives the rotating component 323 to rotate out. The profile 01 moves along the conveying direction of the belt conveyor line 31 until the blocking component 324 on the rotating component 323 abuts against the internal reinforcing ribs of the profile, positioning the profile and preparing for subsequent profile flipping. The blocking component 324 is an elastic component to avoid hard contact that could damage the profile 01.

[0041] The conveying mechanism 4 includes a gantry frame 41, a drive mechanism 42 mounted on the gantry frame 41, a movable frame 43 located at the movable end of the drive mechanism 42, a lifting drive component 44 mounted on the movable frame 43, a lifting support beam 45 driven by the lifting drive component 44 to move up and down, and several sets of material picking modules 46 arranged along the length direction of the lifting support beam 45. The drive mechanism 42 is an X-axis drive module, a Y-axis drive module, or an XY-axis drive module. The material picking module 46 includes two sets of material picking structures arranged opposite each other along the width direction of the lifting support beam 45. The material handling structure has a pair of relatively movable gripping claws 461 and a detection component 462 that can move with the lifting support beam 45 to identify the material handling position; the opposing surfaces of the pair of gripping claws 461 are provided with horizontally outwardly extending gripping parts 4611 for supporting the bottom of the pallet, and the bottom surface of the pallet 02 is provided with a material handling positioning groove 020 that cooperates with the gripping parts 4611 for easy gripping; the detection component 462 includes a sensing plate 4621 movably mounted on the lifting support beam 45 via a Z-axis slide rail, and a sensing sheet 4 mounted on the sensing plate 4621. 622 and a sensor 4623 installed on the lifting support beam 45 to sense the sensing plate 4622. The lifting support beam 45 stops descending when the sensor 4623 senses the sensing plate 4622. The profiles 01 in the material frame 00 are stacked layer by layer, and each layer of profiles 01 is separated by a pallet 02. When the upper layer of profiles 01 is picked up and moved, the height of the lower layer of profiles 01 is lower than the original picking height. The picking height changes with each layer of profiles 01 moved. Picking position identification: The sensing plate 4621 moves down with the lifting support beam 45 until it senses the plate 4622. The lower end of the sensing plate 4621 abuts against the upper pallet 02 in the material frame. The lifting support beam 45 continues to move downward, and the sensing plate 4621 is lifted by the upper pallet 02. The sensor 4623 senses the sensing element 4622, and the lifting support beam 45 stops descending. At this time, the picking claw 461 moves down to the height of the bottom surface of the upper pallet 02. A pair of picking claws 461 are guided and quickly inserted into the picking positioning groove 020 on the bottom surface of the pallet 02 to grab a layer of profile and the pallet. A buffer block is also installed at the bottom of the sensing plate 4621 to further reduce the impact of the sensing plate 4621 on the pallet 02 when it moves downward.

[0042] The flipping mechanism 5 includes several sets of spaced rotating disks 51, cylinders 52 mounted on the rotating disks 51, gripper cylinders 53 driven by the cylinders 52 to extend, gripper blocks 54 mounted on the two gripper arms of the gripper cylinders 53 for clamping the profile, and a drive structure 55 for driving the several sets of rotating disks 51 to rotate synchronously. The drive structure 55 includes a base plate 551, a main drive shaft 552, gears 553, a sliding frame 554, a rack 555, a push-pull cylinder 556, and a driven shaft 557. The main drive shaft 552 is rotatably mounted on the base plate 551, and two gears 553 are mounted on the main drive shaft 552. A sliding frame 554 is slidably mounted on the base plate 551. The moving frame 554 and the sliding frame 554 are equipped with racks 555 that mesh with gears 553 for transmission. A push-pull cylinder 556 is installed on the base plate 551 to move the sliding frame 554. Each rotating disk 51 is mounted on a driven shaft 557, which is rotatably mounted on the base plate 551. The main drive shaft 552 and the driven shaft 557 are synchronously connected via a pulley assembly. When the upper layer of profile conveyed in the conveying module 3 approaches the flipping mechanism 5, i.e., when the blocking component 32 abuts against the outer profile 01, the piston rod of the cylinder 52 extends, driving the gripper cylinder 53 to extend. The gripper cylinder 53 drives the two gripper blocks 54 to clamp the A-side of the profile. The blocking component 32 resets, making way for the flipping. (Reference) Figure 13 The piston rod of the push-pull cylinder 556 retracts, causing the rack 555 to move to the left. Through the meshing transmission of the rack 555 and gear 553, the main drive shaft 552 rotates clockwise. Through the pulley assembly, the rotating disk 51 on the drive shaft 557 rotates synchronously, and the profile B side changes from a vertical state to a horizontal state. The profile changes from a right-angle opening facing upwards to a right-angle opening facing downwards. The drive structure 55 uses the meshing transmission of the rack 555 and gear 553 to drive several rotating disks 51 to rotate synchronously. Compared with the motor drive, this drive structure 55 is more stable and the transmission is smoother.

[0043] The transfer mechanism 6 includes a frame 61, an X-axis servo module 62 mounted on the frame 61, a transfer frame 63 driven horizontally by the X-axis servo module 62, several sets of transfer gripper cylinders 64 mounted on the transfer frame 63 for gripping the profile 01, a Z-axis servo module 65 mounted on the frame 61, a lifting frame 66 driven vertically by the Z-axis servo module 65, at least two pen-shaped cylinders 67 horizontally mounted on the lifting frame 66, and a pen-shaped cylinder... A cylinder 67 drives the extension of a transfer platform 68 for receiving profile 01. The transfer platform 68 is slidably connected to the lifting frame 66 via a linear slide rail. The transfer platform 68 is provided with two positioning grooves 680 for placing profile 01. The transfer gripper cylinder 64 sequentially grabs and flips the profile, and transfers it to the transfer platform 68 via the X-axis servo module 62. After the transfer platform 68 is full of profiles, the transfer platform 68 is driven to move downward by the Z-axis servo module 65.

[0044] The output mechanism 7 includes several sets of conveying components synchronously connected by sprocket assemblies. A clearance space is reserved between two adjacent sets of conveying components for the transfer platform 68 of the transfer mechanism 6 to perform lifting and lowering movements. The conveying components are driven to rotate by a motor. The conveying components include a rotatably mounted drive shaft 71, a conveying roller 72 mounted on the drive shaft 71, and limiting baffles 73 mounted on the drive shafts 71 on both sides of the conveying roller 72. The limiting baffles 73 limit the width of the profile A surface and the profile C surface to prevent the profile 01 from tilting and deviating from the conveying trajectory during the conveying process.

[0045] A feeding method for a profile feeding device includes the following steps: S1. The dual-carrying trolley 2 is equipped with two carrying positions. One carrying position recovers the empty material frame that has been taken out of the first material position 101. The other carrying position transports the material frame 00 filled with profile 01 to the first material position 101 and transfers the empty material frame to the second material position 102. S2. The conveying mechanism 4 drives several sets of material picking modules 46 to move synchronously. The sliding sensor plate 4621 moves down with the material picking module 46 and abuts against the upper tray 02 in the material frame. The picking claw 461 continues to move down with the material picking module 46 until the sensor 4623, which moves synchronously with the picking claw 461, senses the sensor piece 4622 on the sensor plate 4621. A pair of relatively moving picking claws 461 are guided to quickly insert into the picking positioning groove 020 on the bottom surface of the tray 02, and the upper profile 01 and the tray 02 in the material frame at the first material position 101 are transported together to the conveying module 3. S3. The pallets 02, which are alternately arranged with the conveying module 3, fall into the empty material frame 00 at the second material position 102. The blocking component 32 rotates out, and the piston rod of the blocking cylinder 325 extends to drive the rotating part 323 to rotate out. The upper profile 01 moves along the conveying direction of the belt conveyor line 31 until the blocking part 324 of the blocking component 32 abuts against the inner reinforcing rib of the outermost profile. S4, the piston rod of cylinder 52 extends, driving the gripper cylinder 53 to extend. The gripper cylinder 53 drives the two gripper blocks 54 to clamp the A surface of the profile. The blocking component 32 rotates and resets, the flipping mechanism 5 flips, the piston rod of the push-pull cylinder 556 retracts, driving the rack 555 to move to the left. Through the meshing transmission of rack 555 and gear 553, the main drive shaft 552 rotates clockwise. Through the pulley assembly, the rotating disk 51 on the drive shaft 557 rotates synchronously, and the B surface of the profile, which is perpendicular to the A surface of the profile, turns to a horizontal state. S5. The transfer mechanism 6 sequentially transfers the flipped profile 01 to the transfer platform 68, and uses the reinforcing rib D parallel to the B side of the profile as the positioning reference to position multiple profiles 01. S6. The transfer platform 68 moves down vertically, and multiple profiles 01 move down and are supported by several sets of conveying components that are alternately set with the transfer platform 68. The reinforcing ribs D on the profiles 01 fall on the conveying rollers 72 of the conveying components. The conveying rollers 72 rotate to output the profiles 01 and connect them with the subsequent processing equipment. S7. When the profile 01 in the material frame 00 at the first material position is completely removed, the double-load trolley 2 is connected to the front-end material frame feeding equipment and inputs the material frame 00 filled with profile 01 and pallet 02. S8. The material frame 00 at the second material position is filled with pallets 02. The other load position of the dual-load trolley 2 is input to the material frame 00 filled with pallets and outputs it.

[0046] This invention provides a profile feeding device, processing equipment, and feeding method, which realizes continuous profile feeding, accurate material identification, synchronous and stable flipping, and precise transfer positioning, greatly improving the degree of automation and production efficiency.
