Description

Technical Field

[0001] This application relates to the technical field of loading and unloading conveying devices, and in particular to an automatic loading and unloading equipment for bundled materials. Background Technology

[0002] Angle steel is widely used in the manufacturing of steel structure frames, building supports, power poles, and mechanical components. In order to reduce logistics and transportation costs and improve workshop turnover efficiency, angle steel is generally delivered to the processing production line in bundles. Therefore, the automated loading and unloading capability of bundled materials is a key factor in determining the production efficiency and operating cost of the entire profile processing line.

[0003] Currently, the processing of bundled angle steel in the industry generally involves unpacking the bundled angle steel and placing it on a bundled feeding mechanism for conveying. Then, a gantry robot picks up the angle steel one by one from the feeding position and transfers it to the downstream processing device for secondary processing. Although this model has replaced manual handling and feeding to a certain extent, it still has obvious technical defects in actual production and operation.

[0004] First, the process of changing the entire bundle of materials requires the machine to be stopped, which severely restricts the continuity of production. Due to the layout limitations of single-station feeding, when a bundle of angle steel is processed and needs to be replaced with new material, the operator must first stop the operation of the gantry robot. Only after the equipment has completely stopped can the operator enter the work area to complete the unpacking, alignment and replacement of the entire bundle of materials. During the material replacement period, the gantry robot and the downstream processing equipment are in an idle standby state and cannot produce continuously, which affects work efficiency. Summary of the Invention

[0005] Therefore, it is necessary to provide an automatic loading and unloading equipment for bundled materials to address the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic loading and unloading equipment for bundled materials, comprising a bundled feeding mechanism, and further comprising: A ground rail mechanism, wherein the bundled feeding mechanism is mounted on the ground rail mechanism; Multiple sets of buffer material leveling mechanisms are arranged in parallel, and the buffer material leveling mechanisms are used to store angle steel conveyed by the bundled feeding mechanism; The material unloading mechanism is installed on the ground rail mechanism and is arranged parallel to the bundled feeding mechanism. It is used to transport the angle steel remaining on the buffer material level mechanism after processing. An adjustment mechanism is installed on the buffer material level mechanism. The adjustment mechanism is used to flip the inverted angle steel so that the angle steel is placed in a V-shape. The pushing assembly includes a telescopic cylinder and a push plate. The telescopic cylinder is mounted on a base, and the push plate is rotatably connected to the telescopic end of the telescopic cylinder. It also includes a reset spring and a magnetic ball. The reset spring is mounted on the base, and the magnetic ball is mounted on the other end of the reset spring. The magnetic ball is used to magnetically fix the push plate. The positioning assembly includes a second torsion spring shaft and a positioning shaft. The second torsion spring shaft is rotatably connected between the V-groove and the placement opening. The positioning shaft is mounted on the second torsion spring shaft. There is a gap between the second torsion spring shaft and the positioning shaft. One side of the inverted angle steel will enter the gap along the positioning shaft.

[0007] To facilitate the reversal of the angle steel, preferably, the V-groove is used to place the V-shaped angle steel, the placement opening is used to place the inverted angle steel, and the positioning component is used to position the angle steel.

[0008] Preferably, the mounting rod and the pull rod are provided. The mounting rod is mounted on the base, the return spring is located inside the mounting rod, the pull rod is slidably connected inside the mounting rod, and the two ends of the return spring are fixedly connected to the bottom of the mounting rod and the pull rod, respectively. The magnetic ball is mounted on the top of the pull rod.

[0009] Preferably, a first torsion spring shaft is installed on the telescopic end of the telescopic cylinder, and the push plate is rotatably connected to the telescopic end of the telescopic cylinder through the first torsion spring shaft.

[0010] Preferably, a limiting block for restricting the sliding of the pull rod is installed inside the mounting rod.

[0011] Preferably, a connecting rod is mounted on the second torsion spring shaft, and the positioning shaft is connected to the second torsion spring shaft through the connecting rod.

[0012] Preferably, the reversing mechanism is slidably mounted on the buffer material leveling mechanism.

[0013] Compared with the prior art, the present invention provides an automatic loading and unloading equipment for bundled materials, which has the following beneficial effects: It can automate the entire process of material loading, buffering, and unloading, with seamless connection between each process and no waiting time. It can complete the replacement of the whole bundle of materials without stopping the gantry operation, effectively reducing the labor intensity of the operation, ensuring the efficiency of gantry loading and the overall processing rhythm, steadily improving the production and processing efficiency, and helping the process to advance efficiently. At the same time, it can optimize the working environment of operators, avoid workers from entering the robot's working area, and significantly improve the comfort of operation and production safety.

[0014] The reversing mechanism can automatically adjust the forward and reverse posture of the angle steel, so that the angle steel can be uniformly kept in a positive V state and directly enter the subsequent processing, eliminating the manual reversing process and improving the continuity of the processing flow.

[0015] The positioning structure in the reversing mechanism can position the angle steel when it is placed, preventing it from tilting due to its own vibration when it falls. This reduces the possibility of the angle steel tilting and failing to fall into the slot during the subsequent flipping process. At the same time, the positioning structure can limit and guide the angle steel during the flipping process, preventing the right-angled surface of the angle steel from directly impacting the slot wall and causing shaking and jamming. This ensures that the flipping process is smooth and controllable, and also reduces the damage caused by collisions to the components.

[0016] Meanwhile, the subsequent resetting force of the push plate assists in the flipping of the angle steel, accelerating the speed at which the angle steel falls into the groove, avoiding direct impact of the right-angle end of the angle steel on the groove wall and causing structural damage, and can also reduce the vibration generated when the angle steel falls into the groove, preventing the angle steel from shaking and getting stuck in the groove, and ensuring that the angle steel is accurately and stably positioned.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Example: Refer to Figure 1 and Figure 2 An automatic loading and unloading equipment for bundled materials includes a bundled feeding mechanism 2, which can transport and store bundled angle steel, and then use a gantry robot to clamp and place it in a designated position. However, when preparing to replace a whole bundle of materials, this method is limited by the single-station feeding limitation. When a bundle of angle steel is finished and needs to be replaced with new material, the operator must first stop the operation of the gantry robot and wait for the equipment to stop completely before entering the work area to unpack, align and load the whole bundle of materials. This process not only significantly increases the labor intensity of the operation and reduces the gantry loading efficiency, but also slows down the processing pace, thereby affecting the overall production and processing efficiency and hindering the efficient advancement of the process. To solve the above problems, the following implementation methods can be adopted, such as... Figures 1-4As shown, the system is equipped with a ground rail mechanism 1, a material return mechanism 3, multiple buffer material level mechanisms 4, and a reversing mechanism 5. The reversing mechanism 5 includes a base with a V-groove 501 and a placement port 502, a pushing component, and a positioning component. The bundling feeding mechanism 2 and the material return mechanism 3 are installed in parallel on the ground rail mechanism 1. The multiple buffer material level mechanisms 4 are arranged in parallel, and the gantry robot is located at the buffer material level mechanism 4. The reversing mechanism 5 is installed on the buffer material level mechanism 4. In operation, workers place the angle steel at the designated placement point according to its material and specifications. Workers select the required angle steel according to the processing program issued by the angle steel production line, untie the wires wrapping the angle steel bundles, and hoist them onto the bundling feeding mechanism 2. The position of the bundling feeding mechanism 2 is adjusted through the ground rail mechanism 1 to align with the corresponding buffer material level mechanism 4. The bundling feeding mechanism 2 is then activated to transport the angle steel into the corresponding buffer material level mechanism 4. Subsequently, the bundling feeding mechanism 2 moves again on the ground rail mechanism 1, waiting for new angle steel to be placed. Angle steel is conveyed to another buffer material leveling mechanism 4. Then, the truss robot arm at the corresponding buffer material leveling mechanism 4 uses a vision camera to determine the positive and negative V-shaped positions of the angle steel, guiding the robot arm to grab the angle steel. Based on the positive and negative V-shaped positions of the grabbed angle steel, the positive V-shaped angle steel is placed directly on the V-groove 501, and the negative V-shaped angle steel is placed on the placement opening 502. The angle steel is flipped onto the V-groove 501 by the pushing component and the positioning component, facilitating subsequent processing. The remaining angle steel after processing is moved to the unloading mechanism 3 by the ground rail mechanism 1. The buffer material leveling mechanism 4 reverses and conveys the remaining angle steel to the unloading mechanism 3, waiting to be moved to the surplus material storage area by a forklift. In this way, automated feeding, buffering and unloading operations can be realized. The whole process is seamless and without interruption, effectively optimizing the operator's working environment, avoiding contact between the robot arm and the operator's working environment, and the rotated angle steel maintains the positive V-shaped position, which can be directly processed later, significantly improving the comfort of operation, and thus steadily improving the overall operation efficiency.

[0021] In a preferred embodiment, such as Figure 7 , Figure 8 As shown, the pushing assembly includes a telescopic cylinder 701 and a push plate 702. The telescopic cylinder 701 is mounted on the base, and the push plate 702 is rotatably connected to the telescopic end of the telescopic cylinder 701. The telescopic cylinder 701 pushes the push plate 702 to move, so that the push plate 702 contacts the inclined inner wall of the angle steel. Then, with the cooperation of the positioning assembly, the angle steel is flipped into the V-groove 501.

[0022] In a preferred embodiment, such as Figures 5-8As shown, the positioning assembly includes a second torsion spring shaft 901 and a positioning shaft 902. The second torsion spring shaft 901 is rotatably connected between the V-groove 501 and the placement opening 502. The positioning shaft 902 is mounted on the second torsion spring shaft 901. There is a certain gap between the second torsion spring shaft 901 and the positioning shaft 902. When the gantry robot places the inverted angle steel into the placement opening 502, one side of the angle steel will enter the gap along the positioning shaft 902, which plays a positioning role and prevents the angle steel from tilting due to vibration when it falls. This reduces the possibility that the angle steel will tilt and fail to enter the V-groove 501 during subsequent flipping. Furthermore, during subsequent flipping, the positioning shaft 902 can abut against the inner wall of the angle steel, while the second torsion spring shaft 901 abuts against the angle steel. On the outer wall, when rotating, the angle steel will rotate along the second torsion spring shaft 901 and then enter the V-groove 501. This method can effectively prevent the angle steel from tilting due to vibration when it falls, reducing the possibility of the angle steel tilting and failing to enter the V-groove 501 during subsequent flipping. On the other hand, the second torsion spring shaft 901 and the positioning shaft 902 play a restrictive role in the rotation of the angle steel. When entering the V-groove 501, the side of the angle steel will contact and slide along the inner wall of the left side of the V-groove 501, preventing the right-angle end of the angle steel from directly impacting the side wall of the V-groove 501. This reduces damage to the V-groove 501 and also reduces the possibility of the angle steel getting stuck in the V-groove 501 due to vibration, making it easier for subsequent processing.

[0023] In a preferred embodiment, such as Figure 8 As shown, a first torsion spring shaft 6 is installed on the telescopic end of the telescopic cylinder 701. The push plate 702 is rotatably connected to the telescopic end of the telescopic cylinder 701 through the first torsion spring shaft 6. With the setting of the first torsion spring shaft 6, the push plate 702 can reset itself to the initial tilt state after pushing the angle steel to flip and move, which is convenient for subsequent contact with the angle steel.

[0024] In a preferred embodiment, such as Figure 7 , Figure 8As shown, a mounting rod 801, a return spring 802, a pull rod 803, and a magnetic ball 804 are installed in a base with a V-groove 501 and a placement opening 502. The mounting rod 801 is mounted on the base, the return spring 802 is located inside the mounting rod 801, and the pull rod 803 is slidably connected inside the mounting rod 801. Both ends of the return spring 802 are fixedly connected to the bottom of the mounting rod 801 and the pull rod 803, respectively. The magnetic ball 804 is installed on the top of the pull rod 803. The magnetic ball 804 is used to attract the push plate 702, and its magnetic attraction force is greater than the elastic force of the return spring 802. When the push plate 702 moves, under the combined action of the magnetic force and the spring tension, the push plate 702 is pulled to a rightward tilt, stretching the return spring 802 and causing the pull rod 803 to... The mounting rod 801 slides within the rod. During use, the magnetic ball 804 magnetically attracts the bottom of the push plate 702, fixing the push plate 702 in place. When the push plate 702 moves under the action of the telescopic cylinder 701, it tilts to the right due to the magnetism of the magnetic ball 804 and the tension of the return spring 802. As the push plate 702 continues to move, it overcomes the elasticity of the return spring 802, causing the return spring 802 to extend. The pull rod 803 slides within the mounting rod 801, and the magnetic ball 804 moves synchronously with the push plate 702 until the push plate 702 contacts the inner wall of the angle steel, causing the angle steel to flip. When the telescopic cylinder 701 resets, the magnetic ball 804 will reset synchronously under the action of the return spring 802, facilitating subsequent use.

[0025] In specific implementation methods, such as Figures 9-15 As shown, the initial state of the push plate 702 after the first torsion spring shaft 6 drives it to reset can be tilted to the left, specifically as follows: Figure 14 , Figure 15 As shown, a limiting block 805 for restricting the sliding of the pull rod 803 is installed inside the mounting rod 801. During use, since the push plate 702 is initially tilted to the left, the telescopic cylinder 701 needs to shorten the distance more during reset to allow the push plate 702 to contact the magnetic ball 804 and be attracted and positioned. Subsequently, when the push plate 702 moves under the action of the telescopic cylinder 701, it still first overcomes the elastic force of the reset spring 802, causing the push plate 702 to be tilted to the right, facilitating contact and rotation with the inner wall of the angle steel. A limit block 805 is provided to restrict the stroke of the pull rod 803. When the angle steel, under the action of the push plate 702, has one side perpendicular to the placement opening 502 and is about to flip towards the V-groove 501, the pull rod 803 cannot continue to move due to the action of the limit block 805, while the push plate 702 continues to move. The pulling force is greater than the attraction force of the magnetic ball 804 on the push plate 702, and the push plate 702 separates from the magnetic ball 804. The magnetic ball 804 resets under the action of the return spring 802, and the push plate 702 will also quickly rotate and reset under the action of the first torsion spring shaft 6. Figure 14 As shown, since the push plate 702 is initially tilted to the left, its rapid reset will cause the angle steel to contact the upper inclined surface during rotation, accelerating its rotation. This rotation will then drive the second torsion spring shaft 901 and the positioning shaft 902 to rotate, causing the side of the angle steel to contact the inclined surface of the V-groove 501. The angle steel then falls along the inclined surface into the bottom of the V-groove 501, preventing the right-angled end from hitting the inclined surface of the V-groove 501 and reducing damage. Furthermore, due to the rapid rotation, the edge of the angle steel will always be in contact with the positioning shaft 902 and the second torsion spring shaft 901 during rotation. This reduces the vibration generated by the angle steel contacting the side of the V-groove 501, preventing it from wobbling within the V-groove 501 and avoiding issues such as... Figure 15 The angle steel shown is inserted into the V-groove 501, which facilitates subsequent processing.

[0026] During this process, since the speed at which the push plate 702 resets is much greater than the speed at which the angle steel rotates, the push plate 702 will apply an instantaneous, forward-directing boosting force to the inclined surface of the flipped angle steel located above. This boosting force is not used to rigidly block or drastically change the trajectory of the angle steel, but to provide the angle steel with the final rotational acceleration.

[0027] In a preferred embodiment, the reversing mechanism 5 is slidably mounted on the buffer material level mechanism 4 and its position is fixed by bolts. By adjusting the position of the reversing mechanism 5 on the buffer material level mechanism 4, it can be adapted to angle steel of different lengths, which facilitates processing and improves the applicability of the device.
