Description

Technical Field

[0001] This invention relates to the field of steel coil palletizing technology, specifically to an automatic winding and palletizing system for packaging steel strips. Background Technology

[0002] After being cut by a slitting machine, the steel strip is wound into steel strip coils by an automatic winding device. The steel strip coils are then bundled and transported to the palletizing station. The quality of the steel strip coils being palletized directly affects the subsequent transportation and warehousing work.

[0003] Currently, the internal support gripping structure is commonly used when stacking steel strips. The working principle is to insert a gripping mechanism with multiple support claws into the through hole in the center of the steel strip roll. The support claws expand radially outward, and when the support claws support the inner wall of the steel strip roll, the steel strip roll can be gripped and transported.

[0004] In the existing technology, the internal support gripping method has a technical drawback: the support claws exert a local outward force on the innermost steel strip. Due to the thinness and low rigidity of the steel strip, and the fact that the bundled steel strip roll itself has a certain degree of slack, when the gripping mechanism drives the steel strip roll upward, the upward force is concentrated on the innermost steel strip, causing axial interlayer misalignment of the flat inner ring of the steel strip roll. This will affect the overall flatness and neatness after stacking. If the support force of the support claws on the inside of the steel strip roll is increased, it will cause excessive localized stress on the steel strip, which may cause permanent deformation of the inner ring of the steel strip roll. Therefore, a stacking device that can meet the requirements of high-precision steel strip products is needed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic winding and palletizing system for packaging steel strips, so as to achieve high-precision palletizing work that avoids unevenness in the inner circle of the steel strip roll when palletizing the steel strip rolls.

[0006] In one possible implementation, an automatic packaging steel strip winding and palletizing system includes multiple winding devices, a conveying device, and a gantry frame. The multiple winding devices are arranged on the sides of the winding devices, and the gantry frame is located at the end of the conveying device away from the winding devices. The system also includes a handling device, a gripping mechanism, support claw components, and a sensor assembly. The handling device is mounted on the gantry frame and includes a longitudinal sliding column. The lower end of the longitudinal sliding column is provided with a gripping mechanism. The handling device can drive the gripping mechanism to move vertically and laterally. The gripping mechanism is provided with multiple support claw components, which can drive the multiple support claw components to move radially simultaneously, supporting the inner ring of the steel strip roll. The handling device can move the steel strip roll onto a pallet for palletizing by driving the gripping mechanism. When the support claw components contact the steel strip roll, they can support the inner ring or bottom of the steel strip roll. The sensor assembly is located on the handling device and the conveying device below the gantry frame and can detect the steel strip roll.

[0007] The sensor assembly includes a position sensor and a distance sensor. The position sensor is fixedly mounted on the conveying device and can detect the steel strip coils moving below the gantry frame. The distance sensor is fixedly connected to the longitudinal sliding column near the gripping mechanism and can detect the height of the steel strip coils on the pallet. The distance sensor measures the distance between the stacked steel strip coils and the sensor itself to determine the number of coils being stacked. In actual production, situations such as power outages may occur. Traditional counting and stacking methods reset the count to zero after a power outage and start stacking again from zero, which can cause damage to the steel strip coils due to compression.

[0008] The gripping mechanism includes a main rod, parallel rod groups, and support rods. The main rod is fixedly connected to the longitudinal sliding column. Multiple parallel rod groups are circumferentially connected to the main rod at the end away from the longitudinal sliding column. Each parallel rod group has two parallel connecting rods that rotate simultaneously, ensuring the gripper remains vertical during rotation. Each gripper is rotatably connected to multiple connecting rods in the parallel rod groups. Multiple drive cylinders are fixedly mounted on the longitudinal sliding column, and a linkage plate is connected to the output end of each drive cylinder. The main rod passes through the center of the linkage plate, and multiple support rods are rotatably connected to the linkage plate. Each gripper is rotatably connected to one support rod. In this application, there are three parallel rod groups, three support rods, and three gripper components, arranged at 120-degree angles to each other.

[0009] When the linkage disc slides away from the longitudinal sliding column, the support rod can push the support claw component to rotate through the connecting rod, and the multiple support claw components remain in a parallel state when rotating.

[0010] The support claw component includes a support plate and a rubber pad. The rubber pad is disposed on the support plate and can be easily connected by means of straps, etc. The support plate is rotatably connected to multiple connecting rods and support rods, and the rubber pad can contact the inner ring of the steel strip coil.

[0011] The support claw component includes a second support plate, an elastic bag, and a support plate. The second support plate is rotatably connected to a plurality of connecting rods and the support rod. The elastic bag is disposed on the side of the support rod away from the main rod. The elastic bag is filled with granular filler. The support plate is rotatably connected to the lower side of the second support plate. The support plate is in contact with the bottom of the elastic bag.

[0012] When the elastic bag comes into contact with the inner ring of the steel strip roll, the steel strip roll squeezes and deforms the elastic bag. When the longitudinal sliding column drives the gripping mechanism to move upward, the gravity of the steel strip roll squeezes the elastic bag. The filler in the elastic bag flows to the bottom of the steel strip roll, and the elastic bag wraps around the filler. At the same time, the elastic bag squeezes the pallet, causing it to rotate downward to a horizontal angle to support the elastic bag.

[0013] The support claw component includes a support plate three, a pressure plate, and a lower clamping plate. The support plate three is rotatably connected to multiple connecting rods. The support plate three is provided with a sliding groove. The pressure plate is vertically slidably connected in the sliding groove. The pressure plate is rotatably connected to the support rod. The pressure plate extends a support arm toward the side of the support plate three away from the support rod. The pressure plate is provided with a pushing plate. The lower clamping plate is rotatably connected to the support plate three. The lower clamping plate is located below the pressure plate. When the pressure plate slides downward, the pushing plate can push the lower clamping plate to rotate to a horizontal angle. An elastic connector is provided between the pressure plate and the support plate three. The elastic connector in this application can be a spring. The spring pulls the pressure plate towards the upper side of the support plate three, so that when the support rod pushes the pressure plate, the pressure plate moves simultaneously with the support plate three. After the support plate three contacts the steel strip coil and stops moving, the pressure plate slides relative to the support plate three, so that the pressure plate and the lower clamping plate clamp the steel strip coil. When the steel strip coil is released, due to the action of the spring, the pressure plate and the support plate three slide relative to each other first, and then drive the support plate three to move.

[0014] When the support plate three contacts the inner ring of the steel strip coil, it stops moving. At this time, the support rod can push the pressure plate to slide downward on the sliding groove. The pushing plate pushes the lower clamping plate to rotate and contact the lower side of the steel strip coil. The pressure plate continues to slide down and contact the upper side of the steel strip coil.

[0015] The significant technical effects of the embodiments of the present invention are as follows: 1. The present invention increases the support area of ​​the inner side of the steel strip coil by setting rubber pads on the support plate, while maintaining flexible extrusion when extruding the steel strip coil, thereby reducing the deformation of the inner side of the steel strip coil. 2. This invention, by setting up an elastic bag and a support plate, allows the filler inside the elastic bag to flow and flexibly conform to the bottom of the steel strip roll when the elastic bag compresses it. At the same time, the support plate supports the elastic bag, achieving large-area flexible support for the bottom of the steel strip roll, increasing the stress area of ​​the steel strip roll. Meanwhile, the elastic bag can deform as it comes into contact with the steel strip roll, avoiding compression damage to the steel strip roll. 3. By setting up a pressure plate and a lower clamping plate, after the support plate three contacts the steel strip coil, the pressure plate slides on the support plate three, and the pushing plate pushes the lower clamping plate to rotate and contact the lower side of the steel strip coil. At the same time, the pressure plate contacts the upper side of the steel strip coil, thus completing the clamping of the steel strip coil on both the upper and lower sides. The inner circle of the steel strip coil is clamped, and no axial interlayer misalignment will occur. At the same time, the clamping can also clamp any possible misalignment into a flat state.

[0026] Example 1 This illustration shows an automatic winding and palletizing system for packaging steel strips according to an embodiment of the present invention, including multiple winding devices 1, a conveying device 2, and a gantry frame 3. The multiple winding devices 1 are arranged on the side of the winding devices 1, and the gantry frame 3 is located at the end of the conveying device 2 away from the winding devices 1. Please refer to [link / reference]. Figures 1-3 It also includes a conveying device, a gripping mechanism, a support claw component, and a sensor assembly. The conveying device is mounted on the portal frame 3 and includes a longitudinal sliding column 5 and a transverse sliding frame 4. The transverse sliding frame 4 is slidably mounted on the portal frame 3, and the longitudinal sliding column 5 is vertically slidably connected to the transverse sliding frame 4. A gripping mechanism is provided at the lower end of the longitudinal sliding column 5. The conveying device can drive the gripping mechanism to move vertically and laterally. The reciprocating motion sequentially conveys and stacks the steel strip coils. Please refer to [link / reference]. Figure 4The gripping mechanism is equipped with multiple support claw components. The gripping mechanism can drive the multiple support claw components to move radially at the same time to support the inner circle of the steel strip roll. The conveying device can drive the gripping mechanism to move, and then drive the steel strip roll to the pallet for stacking. When the support claw components contact the steel strip roll, they can support the inner circle or bottom of the steel strip roll. The sensor assembly is set on the conveying device and the conveying device 2 at the position below the portal frame 3, and can detect the steel strip roll.

[0027] The sensor assembly includes a position sensor 6 and a distance sensor 7. Please refer to [link / reference]. Figure 3 The position sensor 6 is fixedly installed on the conveyor 2 and can detect the steel strip rolls that have moved to the bottom of the gantry frame 3. The distance sensor 7 is fixedly connected to the longitudinal sliding column 5 near the gripping mechanism and can detect the height of the steel strip rolls on the pallet. The distance between the stacked steel strip rolls and the distance sensor 7 is measured by the distance sensor 7 to determine the number of stacked steel strip rolls. In actual production, power outages may occur. In traditional counting and stacking methods, the count will reset to zero after a power outage and the stacking will start from zero again, which will cause the steel strip rolls to be squeezed and damaged.

[0028] Please see Figures 3-4 The gripping mechanism includes a main rod 101, parallel rod groups, and support rods 105. The main rod 101 is fixedly connected to the longitudinal sliding column 5. Multiple parallel rod groups are circumferentially connected to the end of the main rod 101 away from the longitudinal sliding column 5. Two parallel connecting rods 102 are provided in each parallel rod group. The parallel connecting rods 102 rotate simultaneously, ensuring that the gripper components remain vertical during rotation. Each gripper component is rotatably connected to multiple connecting rods 102 in the parallel rod groups. Multiple drive cylinders 103 are fixedly mounted. Mounted on the longitudinal sliding column 5, a linkage disc 104 is connected to the output ends of multiple drive cylinders 103. A main rod 101 passes through the center of the linkage disc 104. Multiple support rods 105 are rotatably connected to the linkage disc 104. Each support claw component is rotatably connected to a support rod 105. As the output ends of the drive cylinders 103 extend, they push the linkage disc 104. The linkage disc 104 pushes the support rods 105, and the support rods 105 push the support claw components to move away from the main rod 101 and the drive cylinders 103. Figure 4 The state is that the three support claw components are open. The output end of the drive cylinder 103 shortens, which can drive the support claw components to retract. In this application, there are three parallel rod groups, three support rods 105 and three support claw components, which are arranged at 120 degrees to each other.

[0029] When the linkage plate 104 slides away from the longitudinal sliding column 5, the support rod 105 can push the support claw component to rotate through the two connecting rods 102, and the three support claw components remain parallel when rotating.

[0030] The support claw component includes a support plate 201 and a rubber pad 202. The rubber pad 202 is mounted on the support plate 201 and can be easily connected by means of straps, etc. The support plate 201 is rotatably connected to multiple connecting rods 102 and support rods 105. The rubber pad 202 can contact the inner ring of the steel strip coil. Please refer to [link / reference]. Figure 4 The rubber pad 202 can be directly bound to the support plate 201 by means of cable ties or other methods, which is relatively simple to set up. The support plate 201 is in elastic contact with the inner ring of the steel strip roll through the rubber pad 202. The rubber pad 202 can deform as it is squeezed, which increases the contact area with the inner side of the steel strip roll while maintaining the support force. When the conveying device drives the main rod 101 to move, the rubber pad 202 can drive the steel strip roll to move.

[0031] Compared with the prior art, this embodiment provides an automatic winding and palletizing system for packaging steel strips. After the steel strip is wound and bundled by the winding device 1, it is placed on the conveying device 2. The steel strip roll is transported to the position sensor 6, which detects the steel strip roll. The longitudinal sliding column 5 slides downward, and the main rod 101 extends into the center of the steel strip roll. The output end of the drive cylinder 103 extends to push the support rod 105. The support rod 105 pushes the support plate 201 to move away from the main rod 101. The rubber pad 202 supports the steel strip roll. At this time, the handling device can drive the steel strip roll to move and place the steel strip roll on the pallet for palletizing.

[0032] Example 2 Please see Figures 5-7 The support claw component includes a second support plate 301, an elastic bag 302, and a support plate 303. The elastic bag 302 can be made of elastic materials such as rubber. The second support plate 301 is rotatably connected to multiple connecting rods 102 and support rods 105. The elastic bag 302 is located on the side of the support rod 105 away from the main rod 101. The elastic bag 302 is filled with granular filler. The support plate 303 is rotatably connected to the lower side of the second support plate 301. The support plate 303 is in contact with the bottom of the elastic bag 302. Elastic components such as coil springs are provided between the support plate 303 and the second support plate 301, so that the support plate 303 has an upward rotational force.

[0033] When the elastic bag 302 contacts the inner ring of the steel strip roll, the steel strip roll compresses and deforms the elastic bag 302. When the longitudinal sliding column 5 drives the gripping mechanism to move upward, the gravity of the steel strip roll compresses the elastic bag 302. Please refer to [link to relevant documentation]. Figure 6 The filler in the elastic bag 302 flows to the bottom of the steel strip roll. The elastic bag 302 wraps around the filler, and the elasticity of the elastic bag 302 causes the filler to contract. The elastic bag 302 makes large-area contact with the lower side of the steel strip roll, increasing the stress area. At the same time, the elastic bag 302 squeezes the pallet 303, causing it to rotate downwards to a horizontal angle. Please refer to [link / reference]. Figure 7 The tray 303 stops rotating when it reaches a horizontal angle, thus supporting the elastic bag 302.

[0034] Compared with the prior art, this embodiment provides an automatic winding and palletizing system for packaging steel strips. The filler in the elastic bag 302 can provide flexible support to the steel strip roll. When the steel strip roll moves upward, it will squeeze the filler in the elastic bag 302 to move to the lower side of the steel strip roll. At the same time, the elastic bag 302 squeezes the pallet 303 to rotate it to a horizontal angle. The pallet 303 supports the elastic bag 302. The large-area flexible support of the elastic bag 302 can achieve large-area support for the lower side of the steel strip roll, avoiding deformation of the steel strip roll and preventing axial interlayer misalignment on the inner side of the steel strip roll.

[0035] Example 3 Please see Figures 8-10 The support claw component includes a support plate 401, a pressure plate 403, and a lower clamping plate 405. The support plate 401 is rotatably connected to multiple connecting rods 102. A sliding groove 402 is provided on the support plate 401. The pressure plate 403 is vertically slidably connected in the sliding groove 402. The pressure plate 403 is rotatably connected to the support rod 105. A support arm extends from the pressure plate 403 toward the side of the support plate 401 away from the support rod 105. Please refer to [link / reference]. Figure 9 A pushing plate 404 is provided on the pressure plate 403. A lower clamping plate 405 is rotatably connected to the support plate 401. The lower clamping plate 405 is located below the pressure plate 403 and has a protrusion. When the pressure plate 403 slides downward, the pushing plate 404 can push the protrusion on the lower clamping plate 405, causing the lower clamping plate 405 to rotate to a horizontal angle. At the same time, when the pushing plate 404 is between the lower clamping plate 405 and the support plate 401, the lower clamping plate 405 will remain in a horizontal state. An elastic connecting member 406 is provided between the pressure plate 403 and the support plate 401. The elastic connector 406 can be a spring. The spring pulls the pressure plate 403 towards the upper side of the support plate 401, so that when the support rod 105 pushes the pressure plate 403, the pressure plate 403 moves simultaneously with the support plate 401. After the support plate 401 contacts the steel strip coil and stops moving, the pressure plate 403 slides relative to the support plate 401, so that the pressure plate 403 and the lower clamping plate 405 clamp the steel strip coil. When the steel strip coil is released, due to the action of the spring, the pressure plate 403 and the support plate 401 slide relative to each other first, and then drive the support plate 401 to move.

[0036] A groove is provided on the support plate 3 401. The groove is aligned with the inner side of the steel strip coil. The support plate 3 401 stops moving when it contacts the inner ring of the steel strip coil. At this time, the support rod 105 can push the pressure plate 403 to slide downward on the sliding groove 402. The groove is located on the upper side of the lower clamping plate 405. The pushing plate 404 pushes the lower clamping plate 405 to rotate and contact the lower side of the steel strip coil. At this time, the pushing plate 404 continues to slide between the lower clamping plate 405 and the support plate 3 401. The lower clamping plate 405 remains in contact with the lower side of the steel strip coil. The pressure plate 403 continues to slide down and contact the upper side of the steel strip coil, thereby achieving clamping of the steel strip coil on both the upper and lower sides. There will be no axial interlayer misalignment on the inner side of the steel strip coil, and any possible misalignment can be clamped and flattened.

[0037] Meanwhile, when supporting the inner side of the steel strip coil, the lower clamping plate 405 is in direct contact with the inner side of the steel strip coil. At this time, the squeezing plate 404 cannot make the lower clamping plate 405 rotate even when it is squeezed by the lower clamping plate 404. At this time, the steel strip coil can be driven to move by the direct support of the lower clamping plate 405.

[0038] When the steel strip coil is placed on the pallet, when the steel strip coil is at a certain height from the pallet or the steel strip coil below, the output end of the drive cylinder 103 shortens, the support rod 105 pulls the pressure plate 403 upward, the elastic connector 406 shortens, the pressure plate 403 separates from the steel strip coil, and as the pushing plate 404 gradually separates from the lower clamping plate 405, the lower clamping plate 405 rotates to a vertical state under the gravity of the steel strip coil, and the steel strip coil falls onto the pallet below. The lower clamping plate 405 does not contact the pallet or the steel strip coil below, ensuring that the steel strip coil lands smoothly after the lower clamping plate 405 is fully retracted, avoiding the lower clamping plate 405 being pressed between the steel strip coil and the pallet and unable to retract. At this time, the longitudinal sliding column 5 can move downward, and the inner ring of the steel strip coil is supported by the three lower clamping plates 405, completing the position correction of the pallet below, and preventing the position of the steel strip coil below from being inaccurate after it falls.

[0039] like Figure 9 and Figure 10 Compared with the traditional stacking method, the clamping of the steel strip coil by the pressure plate 403 and the lower clamping plate 405 can prevent the inner ring of the steel strip coil from bulging.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
