Description

Technical Field

[0001] The present invention relates to the technical field of steel plate stacking, and in particular to an intelligent unmanned stacking yard device for an automated shearing production line of cold-rolled steel plates. Background Art

[0002] The steel plate stacking paper laying machine is a special equipment used to automatically lay release paper during the steel plate stacking process. Its main function is to accurately lay release paper between steel plate layers to prevent slipping between steel plates due to anti-rust oil. At present, common paper laying machines use an S-shaped laying method to arrange release paper between steel plate layers. However, during actual operation, due to the tension exerted by the paper laying mechanism, the release paper is easily in contact with the sharp edges or burrs at the cutting port of the steel plate, causing the paper to be scratched or even torn, affecting the normal progress of the paper laying operation.

[0003] Furthermore, after the steel plate is cut, the metal debris remaining on the surface is subjected to interlayer pressure during the stacking process, which may cause the debris to be pressed into the surface of the steel plate or produce scratches, which not only affects the appearance quality of the product, but also damages the surface protective coating, thereby reducing the corrosion resistance of the steel plate. Summary of the Invention

[0004] In order to overcome the disadvantage that when a steel plate stacking paper laying machine automatically lays paper between steel plate layers in an S-shaped laying manner, the isolation paper is easily scratched by the burrs on the steel plate cutting port due to the tension, thereby affecting the normal paper laying operation, the present invention provides an intelligent unmanned stacking yard device for an automated cold-rolled steel plate shearing production line.

[0005] The technical implementation plan of the present invention is: an intelligent unmanned stacking yard device for an automated shearing production line of cold-rolled steel plates, comprising a carrying platform; a supporting frame for supporting steel plates is placed on the carrying platform; it also comprises a paper laying assembly, a biaxial movable machine, a motor 1, a limiting roller and a cutter; a paper laying assembly for laying release paper is provided on the carrying platform; a biaxial movable machine is provided on the carrying platform; a motor 1 is connected to the biaxial movable machine; a limiting roller for limiting release paper is rotatably connected to the biaxial movable machine; the output end of the motor 1 is fixedly connected to the limiting roller; and a cutter for cutting release paper is provided on the limiting roller.

[0006] As an improvement to the above-mentioned scheme, the paper laying assembly includes a biaxial movable machine, a fixed block, a carrying roller, a second motor and a correction roller; the biaxial movable machine is fixedly connected to the carrying platform; the fixed block is fixedly connected to the biaxial movable machine; the carrying roller for supporting the release paper is rotatably connected to the fixed block; the second motor is fixedly connected to the fixed block; the output end of the second motor is fixedly connected to the carrying roller; and two correction rollers for correcting the release paper are rotatably connected to the fixed block.

[0007] As an improvement to the above solution, the cutting edge of the cutter is arranged in an inclined shape.

[0008] As an improvement to the above solution, it further includes an electromagnetic suction piece; two electromagnetic suction pieces for absorbing metal debris on the steel plate are fixedly connected to the limiting roller.

[0009] As an improvement to the above solution, the surfaces of the limiting roller and the electromagnetic suction plate are both smooth.

[0010] As an improvement to the above scheme, a cleaning component is also included, which includes a telescopic driving member and a fixed plate; a plurality of telescopic driving members are fixedly connected to the supporting platform; a fixed plate is commonly fixedly connected to the telescopic ends of every two adjacent telescopic driving members; each fixed plate is provided with a curved portion for cleaning metal debris on the electromagnetic suction plate; the non-connected end of each curved portion is configured to be in a downwardly bent state.

[0011] As an improvement to the above scheme, it also includes a paper pressing assembly, which includes a rotating ring and a squeezing roller; the rotating ring is rotatably connected to the limiting roller; the squeezing roller for squeezing the release paper is fixed to the rotating ring; the squeezing roller does not contact the outer side of the limiting roller.

[0012] As an improvement to the above scheme, a paper folding system is also included, which includes a telescopic driving member 2 and a pushing block; two telescopic driving members 2 are fixedly connected to each fixed plate; a pushing block for pushing the release paper is commonly fixed to the telescopic ends of the two telescopic driving members 2 on each fixed plate; the height of each pushing block is lower than the limiting roller.

[0013] As an improvement to the above solution, each pushing block is provided with an arc surface on the side facing the release paper.

[0014] As an improvement to the above solution, a sticky coating is provided on the arc surface of each pushing block on the side in contact with the release paper.

[0015] Beneficial effects: The present invention realizes the limiting of the release paper by the limiting roller, preventing the release paper from contacting the port cut by the steel plate, and preventing the release paper from being scratched and torn by the port of the steel plate when being pulled by the bearing roller, thereby ensuring the normal paper laying work on the steel plate;

[0016] The release paper is cut and separated by a cutter. When the steel plate is subsequently removed, the separation of the release paper and the steel plate prevents the position and stability of other steel plates from being affected. This reduces the instability of the entire stack caused by pulling a single steel plate, reduces the risk of the steel plate slipping or tipping, and improves operational safety.

[0017] The electromagnetic suction piece absorbs the small amount of metal debris left after cutting on the upper side of the steel plate, preventing the metal debris from being embedded in or scratching the surface of the steel plate due to the pressure between the layers of the steel plate during stacking, and preventing the metal debris from damaging the protective coating on the surface of the steel plate, thereby ensuring the appearance and anti-corrosion performance of the steel plate;

[0018] The cut end of the release paper is folded and wrapped around the upper side of the steel plate by the pushing block, so that two layers of release paper are laid at the cut end of the steel plate, which is beneficial to enhance the protective effect of the release paper on the cut ends of the two adjacent steel plates, reduce the scratches on the steel plate surface caused by friction or vibration during transportation or stacking, and enhance the protection effect of the steel plate.

[0030] Example 1

[0031] like Figures 1-9 As shown, an intelligent unmanned yard device for an automated cold-rolled steel plate shearing production line includes a carrying platform 1; a supporting bracket 1001 is placed on the carrying platform 1;

[0032] It also includes a paper laying component, a biaxial movable machine 2, a motor 3, a limiting roller 4 and a cutter 5; the paper laying component is provided on the supporting platform 1; the biaxial movable machine 2 is provided on the supporting platform 1; the biaxial movable machine 2 is connected to the motor 3; the biaxial movable machine 2 is rotatably connected to the limiting roller 4; the output end of the motor 3 is fixedly connected to the limiting roller 4; the limiting roller 4 is provided with a cutter 5.

[0033] The paper laying assembly includes a biaxial movable machine 101, a fixed block 102, a carrying roller 103, a second motor 104 and a correction roller 105; the biaxial movable machine 101 is fixedly connected to the carrying platform 1; the fixed block 102 is fixedly connected to the biaxial movable machine 101; the carrying roller 103 is rotatably connected to the fixed block 102; the second motor 104 is fixedly connected to the fixed block 102; the output end of the second motor 104 is fixedly connected to the carrying roller 103; and two symmetrically arranged correction rollers 105 are rotatably connected to the fixed block 102.

[0034] The cutting edge of the cutter 5 is arranged in an inclined shape, which is beneficial to enhancing the cutting effect on the release paper.

[0035] It also includes an electromagnetic suction piece 201; two symmetrically arranged electromagnetic suction pieces 201 are fixedly connected to the limiting roller 4.

[0036] The surfaces of the limiting roller 4 and the electromagnetic suction sheet 201 are both smooth, which facilitates the separation of adhered debris and impurities.

[0037] It also includes a cleaning component, which includes a telescopic drive member 202 and a fixed plate 203; a number of telescopic drive members 202 distributed in a rectangular shape are fixed to the support platform 1, and the telescopic drive member 202 is an electric push rod; a fixed plate 203 is fixed to the telescopic end of each adjacent two telescopic drive members 202; each fixed plate 203 is provided with a curved portion 20301; the non-connected end of each curved portion 20301 is set to a downward bending state.

[0038] It also includes a paper pressing assembly, which includes a rotating ring 301 and a squeezing roller 302; the rotating ring 301 is rotatably connected to the limiting roller 4 through a torsion spring; the squeezing roller 302 is fixed to the rotating ring 301; the squeezing roller 302 does not contact the outer side of the limiting roller 4.

[0039] In the initial state, a layer of isolation paper is laid on the support frame 1001, and the limiting roller 4 and the carrying roller 103 are located on the same side. The following description assumes that the limiting roller 4 and the carrying roller 103 are initially located on the left side of the support frame 1001. When the steel plate is transported out of the shearing production line, the external suction cup is controlled to absorb the steel plate and transfer it to the support frame 1001, so that the steel plate presses the isolation paper onto the support frame 1001. At this time, the dual-axis movable machine 101 is controlled to drive the fixed block 102 and the carrying roller 103 to move toward the right side of the steel plate. In this process, the control Braking motor 2 104 drives the supporting roller 103 to rotate, unwinds the roll isolation paper on the supporting roller 103, and makes the isolation paper flat on the upper side of the steel plate. At the same time, the isolation paper is limited and corrected by two correcting rollers 105 to prevent the isolation paper from shifting during the laying process. In the process of unwinding and laying the isolation paper by the supporting roller 103, the isolation paper is limited by the limiting roller 4 to prevent the isolation paper from contacting the cut end of the steel plate, and to prevent the isolation paper from being scratched and torn by the end of the steel plate when being pulled by the supporting roller 103, thereby ensuring the normal paper laying work on the steel plate.

[0040] After the carrying roller 103 drives the isolation paper to move and lay it to the right side of the steel plate, based on the view from the front to the back, the motor 13 is controlled to drive the limiting roller 4 to rotate counterclockwise 180 degrees, so that the limiting roller 4 drives the cutter 5 to rotate 180 degrees from the side facing the steel plate to contact the isolation paper, and then the dual-axis moving machine 2 is controlled to drive the motor 13 and the limiting roller 4 to move toward the left side of the steel plate, so that the limiting roller 4 drives the cutter 5 to move toward the left side of the steel plate to cut and separate the isolation paper, and then the external suction cup is controlled to stack the next steel plate on the newly laid isolation paper. Compared with the existing method of laying the isolation paper in an S shape between the stacked steel plates, the entire section of isolation paper is divided into separate isolation papers laid on the steel plates. When the stacked steel plates are subsequently taken out, the isolation paper is prevented from affecting the position and stability of other steel plates when it is separated from the steel plates, reducing the instability of the entire stack caused by pulling a steel plate, reducing the risk of the steel plates slipping or tipping over, and improving the safety of operation.

[0041] When the limiting roller 4 drives the cutter 5 to cut the isolation paper between the left ends of the two steel plates, the right end of the steel plate will press and fix the isolation paper extending from the supporting roller 103, and then control the dual-axis moving machine 2 to drive the motor 13, the limiting roller 4 and the cutter 5 to rise, and move from the left side of the steel plate to the right side of the steel plate, so that the limiting roller 4 moves to the bottom of the supporting roller 103, ready to limit the next layer of isolation paper to be laid. When the limiting roller 4 moves on the upper side of the steel plate, it drives the electromagnetic suction piece 201 to pass through the upper side of the steel plate, and the electromagnetic suction piece 201 absorbs the small amount of metal debris remaining after cutting the upper side of the steel plate, so as to prevent the metal debris from being embedded in or scratching the surface of the steel plate due to the interlayer pressure of the steel plate during stacking, and to prevent the metal debris from damaging the protective coating on the surface of the steel plate, thereby ensuring the appearance and anti-corrosion performance of the steel plate.

[0042] When the limiting roller 4 drives the electromagnetic suction piece 201 which has absorbed the metal debris to move to the bottom of the carrying roller 103, the electromagnetic suction piece 201 is moved to the bottom of the carrying roller 103. Figure 8 It is understood that at this time, the limiting roller 4 contacts the release paper again, and at the same time, the upper side of the limiting roller 4 is in contact with the curved portion 20301 on the fixed plate 203 through the release paper, and then the dual-axis movable machine 101 is controlled to drive the fixed block 102 and the carrying roller 103 to move toward the left side of the steel plate again, so that the carrying roller 103 can unwind and lay the paper again, and limit the release paper again through the limiting roller 4. When the carrying roller 103 moves to the left side of the steel plate, based on the front and back as the reference, the motor 13 is controlled to drive the limiting roller 4 to rotate 180 degrees clockwise, so that the limiting roller 4 drives the cutter 5 to rotate 180 degrees clockwise and contact the release paper, preparing to cut the release paper. It should be noted that since the surface of the steel plate is covered with anti-rust oil, the surface of the metal debris remaining on the upper side of the steel plate adheres to the anti-rust oil. While the limiting roller 4 drives the cutter 5 to rotate, the limiting roller 4 The electromagnetic suction piece 201 that has absorbed the metal debris is driven to rotate and contact the release paper. At this time, the magnetization of the electromagnetic suction piece 201 is turned off. When the limit roller 4 drives the electromagnetic suction piece 201 to rotate to the position where the release paper is pressed by the curved portion 20301, the metal debris adhered to the electromagnetic suction piece 201 is covered with rust-proof oil, so that the metal debris is wiped off by the release paper pressed by the curved portion 20301, thereby achieving convenient cleaning of the metal debris adhered to the electromagnetic suction piece 201. After the limit roller 4 drives the electromagnetic suction piece 201 to rotate and clean, the cutter 5 is in contact with the release paper, and then the dual-axis moving machine 2 is controlled to drive the motor 1 3 and the limit roller 4 to continue to move toward the right side of the steel plate, so that the limit roller 4 drives the cutter 5 to move toward the right side of the steel plate, cutting and separating the release paper, and then controlling the external suction cup to stack the next steel plate on the upper side of the release paper, preparing for the next paper laying work.

[0043] It is also considered that, since the isolation paper is in contact with the limiting roller 4, when the limiting roller 4 drives the electromagnetic suction piece 201 that has absorbed the metal debris to rotate and contact the isolation paper for cleaning, the metal debris on the electromagnetic suction piece 201 accumulates at the angle between the isolation paper and the limiting roller 4, making it difficult for the metal debris to separate from the electromagnetic suction piece 201. Therefore, when the limiting roller 4 drives the electromagnetic suction piece 201 that has absorbed the metal debris to move to the right side of the steel plate, combined with Figure 8 Understand that the limiting roller 4 drives the rotating ring 301 and the squeezing roller 302 to move to the right side of the steel plate, and makes the squeezing roller 302 contact with the isolation paper. When the limiting roller 4 drives the electromagnetic suction piece 201 to rotate, the electromagnetic suction piece 201 is rotated. Figure 9 It is understood that the limiting roller 4 drives the squeezing roller 302 to rotate together through the rotating ring 301, so that the squeezing roller 302 squeezes and covers the release paper to the downward bending position of the curved portion 20301. At this time, the limiting roller 4 continues to rotate, and after the squeezing roller 302 is limited by the curved portion 20301, the rotating ring 301 rotates relatively on the limiting roller 4, and at the same time, the torsion spring between the rotating ring 301 and the limiting roller 4 is compressed. As the limiting roller 4 drives the electromagnetic suction plate 201 that has absorbed metal debris to continue to rotate through the curved portion 20301, the curved portion 20301 covered with the release paper scrapes the metal debris on the electromagnetic suction plate 201, preventing the metal debris from accumulating at the angle between the release paper and the limiting roller 4, thereby enhancing the cleaning effect of the metal debris on the electromagnetic suction plate 201.

[0044] When the limiting roller 4 drives the cutter 5 to move toward the right side of the steel plate to cut and separate the release paper, the limiting roller 4 drives the rotating ring 301 and the squeezing roller 302 to move to the right together, so that the squeezing roller 302 is separated from the curved portion 20301, and under the elastic force of the torsion spring on the squeezing roller 302, the rotating ring 301 drives the squeezing roller 302 to rotate and reset to the left side of the limiting roller 4, ready to move toward the left side of the steel plate for the next paper laying work. As the height of the steel plate stack increases, the fixed plate 203 is driven to rise by the telescopic driving member 202, so that the curved portion 20301 always maintains a relative height with the limiting roller 4, so as to clean the metal debris on the electromagnetic suction sheet 201.

[0045] Example 2

[0046] On the basis of Example 1, Figure 1-Figure 5 and Figure 7-Figure 9 As shown, it also includes a paper folding system, which includes a telescopic driving member 2 401 and a pushing block 402; each fixed plate 203 is fixed with two symmetrically arranged telescopic driving members 2 401, and the telescopic driving members 2 401 are electric push rods; the telescopic ends of the two telescopic driving members 2 401 on each fixed plate 203 are commonly fixed with a pushing block 402; the height of each pushing block 402 is lower than the limiting roller 4.

[0047] Each pushing block 402 is provided with an arc surface on the side facing the release paper to prevent the pushing block 402 from squeezing and breaking the release paper.

[0048] The arc surface of each pushing block 402 in contact with the release paper is provided with an adhesive coating, which helps to stick to the release paper and prevent the release paper from detaching from the pushing block 402.

[0049] It is also considered that after the steel plate is cut, burrs and a small amount of molten metal residue will usually appear on the cut end of the steel plate, resulting in an uneven cut end of the steel plate. In the process of transportation or stacking, there is a situation where the surface of the steel plate is scratched due to friction or vibration. Therefore, combined with Figure 9 It is understood that the height of the pushing block 402 is always higher than the upper side of the steel plate. When the limit roller 4 drives the cutter 5 to rotate and contact the release paper, the telescopic driving member 2 401 is controlled to drive the pushing block 402 to move toward the end of the steel plate, so that the pushing block 402 contacts the release paper on the lower side of the limit roller 4. When the limit roller 4 drives the cutter 5 to move toward the right side of the steel plate and cuts and separates the release paper, the release paper is adhered to the release paper by the adhesive coating on the pushing block 402. Figure 8 It is understood that the telescopic driving member 2 401 is then controlled to drive the pushing block 402 to move toward one side of the steel plate, so that the pushing block 402 folds the end of the cut isolation paper and covers it on the upper side of the steel plate, and the isolation paper connected to the carrying roller 103 after being cut is normally laid on the upper side of the steel plate, thereby making the cutting port of the steel plate covered with two layers of isolation paper, which is beneficial to enhance the protective effect of the isolation paper on the cutting ports of the two adjacent steel plates, reduce the situation of scratches on the surface of the steel plate due to friction or vibration during transportation or stacking, and enhance the protection effect of the steel plate. After the pushing block 402 folds the cut end of the isolation paper and wraps it around the upper side of the steel plate, the telescopic driving member 2 401 is controlled to drive the pushing block 402 to continue moving toward the middle of the steel plate, so that the pushing block 402 is separated from the isolation paper. Then, the telescopic driving member 1 202 is controlled to drive the fixed plate 203 to rise, so that the fixed plate 203 drives the telescopic driving member 2 401 and the pushing block 402 to rise. At the same time, the telescopic driving member 2 401 is controlled to drive the pushing block 402 to retract and reset, so as to prevent the isolation paper wrapped around the end of the steel plate from being driven by the pushing block 402 to separate from the steel plate.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
