Description

Technical Field

[0001] This application relates to the field of steel production equipment technology, and in particular to an automated multi-layer angle steel stacking system and its stacking method. Background Technology

[0002] Steel is a material of a certain shape, size, and properties, made from steel ingots, billets, or other steel products through pressure processing. After steel is formed, personnel operate appropriate transport equipment to transport it to a storage location. To improve transport efficiency, multiple steel products are stacked before transportation. The steel stacking conveyor production line includes a conveying device and a lifting device. The lifting device is moved by a truss trolley on a truss. The conveying device includes a conveyor platform and a conveyor chain. The steel is placed on the conveyor platform and transported by the conveyor chain. When the steel moves to the corresponding position, the truss trolley is activated, driving the lifting device to raise the steel to a certain height. At this time, subsequent steel products also move to the corresponding position. The raised steel is then lowered and placed on the conveyor chain, thus achieving automatic stacking of the steel.

[0003] Among various types of steel, angle steel is a metallic material with a V-shaped cross-section, typically made by hot rolling or cold bending. Its applications are wide-ranging, including but not limited to structural support, frame fabrication, reinforcement connections, railings and balustrades, and industrial manufacturing. In general, angle steel is widely used in construction, structural engineering, decoration, and industrial manufacturing due to its stability, strength, and versatility.

[0004] Because of the special shape of angle steel, when stacking, the openings of the angle steel in the upper and lower adjacent layers need to be set in opposite directions, and the angle steel of the upper layer should be placed across the sides of the adjacent angle steel of the lower layer to improve the stability of the angle steel stack and reduce the possibility of tilting and misalignment. However, traditional steel stacking and conveying production lines are difficult to automatically stack angle steel. Summary of the Invention

[0005] The purpose of this application is to provide a more automated multi-layer angle steel stacking system and its stacking method.

[0006] Firstly, the automated multi-layer angle steel palletizing system provided in this application adopts the following technical solution:

[0007] An automated multi-layer angle steel stacking system includes:

[0008] The transmission mechanism includes a transmission platform and a transmission chain, wherein the transmission chain is rotatably connected to the transmission platform and is capable of moving the angle steel.

[0009] A support mechanism is connected to the transmission platform;

[0010] The adsorption mechanism includes a mounting frame, a limiting plate, and a magnetic suction assembly. The mounting frame has a connection hole and can be connected to a truss trolley through the connection hole. The magnetic suction assembly is rotatably connected to the mounting frame. The limiting plate has several limiting grooves and is connected to the magnetic suction assembly.

[0011] By adopting the above technical solution, when multiple angle steels are transported to the appropriate position on the conveyor frame via the conveyor chain, the truss trolley is activated to drive the adsorption mechanism to move vertically until the magnetic adsorption component is located at the lower end of the angle steel group formed by the multiple angle steels. The magnetic adsorption component is then activated to adsorb the multiple angle steels and lift them vertically upward to a certain height. At this time, the subsequent angle steel groups also move to the appropriate position. The magnetic adsorption component that has already adsorbed one group of angle steels is rotated to continue adsorbing the subsequent angle steels. By rotating the magnetic adsorption component back and forth to adsorb the angle steels, the stacking of angle steels is achieved. This method has a higher degree of automation and is conducive to improving work efficiency.

[0012] Optionally, the magnetic attraction assembly includes a magnetic attraction unit, a control unit, and a drive unit. The control unit is connected to both the magnetic attraction unit and the drive unit. The drive unit is connected to the magnetic attraction unit and can drive the magnetic attraction unit to rotate. The drive unit includes a mounting sleeve, an output shaft, and a drive cylinder. The mounting sleeve is fitted onto one end of the output shaft and connected to the mounting bracket. The output shaft passes through the mounting bracket and the magnetic attraction unit in sequence and is connected to the drive cylinder.

[0013] By adopting the above technical solution, when the magnetic suction component attracts the first group of angle steel, the control unit controls the drive unit to drive the magnetic suction unit to flip and start the magnetic suction unit, so that the angle steel is attracted by the magnetic suction unit. Then, the drive unit is controlled to flip in the opposite direction to attract the next group of angle steel. The control unit controls the magnetic suction unit to stack the angle steel, which helps to improve the stacking efficiency.

[0014] Optionally, the output shaft is provided with a circuit hole and an air passage hole. The circuit hole is opened along the length of the axis of the output shaft, and the air passage hole is opened from one end sidewall of the output shaft and extends to the other end sidewall of the output shaft. The control unit is connected to the output shaft through the circuit hole and the air passage hole.

[0015] During the adsorption of angle steel, the magnetic attraction component needs to be powered to operate normally. Therefore, it generally needs to be connected with a corresponding circuit mechanism and air circuit structure. By adopting the above technical solution, the corresponding circuit lines can be connected to the external power supply system through the circuit holes, and the corresponding air circuit lines can also be connected to the external air supply system through the air circuit holes to ensure the normal operation of the magnetic attraction component. By opening circuit holes and air circuit holes on the output shaft, the circuit and air circuit of the adsorption mechanism are highly integrated, which is conducive to optimizing the circuit and air circuit structure.

[0016] Optionally, the support mechanism includes a first fixed frame and a second fixed frame, the first fixed frame and the second fixed frame being located at the bottom end of the transmission frame and both being connected to the transmission frame.

[0017] When the transmission mechanism transports angle steel, the transmission platform is subjected to a large load, which may cause the transmission mechanism to overturn and affect its normal operation. By adopting the above-mentioned technical solution, the first fixed platform and the second fixed platform support the transmission platform, which helps to improve the stability of the transmission platform.

[0018] Optionally, a buffer mechanism is connected to the second fixed frame. The buffer mechanism includes a linkage assembly, a connecting sleeve, and an elastic element. The second fixed frame and the transmission frame are rotatably connected through the linkage assembly. The connecting sleeve is connected to the second fixed frame. The linkage assembly passes through the connecting sleeve and is connected to the elastic element. Both ends of the elastic element are connected to limit cylinders. One limit cylinder is connected to the connecting sleeve, and the other limit cylinder is connected to the linkage assembly.

[0019] When the magnetic suction component attracts the angle steel, it moves towards the angle steel. If the magnetic suction component moves excessively, it will make direct rigid contact with the transfer frame, which may damage the transfer frame. By adopting the above technical solution, when the magnetic suction component contacts the transfer frame, the transfer frame will adaptively rotate relative to the second fixed frame, and the elastic element will contract. When the magnetic suction component moves away, the contracted elastic element will rebound, allowing the transfer frame to return to its initial state. This reduces the possibility of the magnetic suction component damaging the transfer frame and improves the safety of the angle steel stacking system.

[0020] Optionally, the linkage assembly is rotatably connected to a first drive rod, a second drive rod, and a third drive rod. The first drive rod is fixedly connected to the transmission frame, the second drive rod is rotatably connected to the second fixed frame, and a connecting sleeve is connected to the second fixed frame. The third drive rod passes through the connecting sleeve, one of the limiting cylinders, and the elastic element in sequence and then connects to the other limiting cylinder.

[0021] By adopting the above technical solution, when the drive assembly presses down on the transmission platform, the first drive rod moves downward, causing the transmission platform to rotate adaptively relative to the second fixed platform. The downward-moving first drive rod then drives the second drive rod to rotate counterclockwise, causing the third drive rod to move upward. Under the action of the limiting sleeve, the elastic element contracts. When the drive assembly moves away, the elastic element returns to its initial state. Through the mutual rotation of multiple drive rods, the load on the transmission platform is effectively reduced, which is beneficial to protecting the transmission platform.

[0022] Optionally, a limiting mechanism is also provided on the second fixed frame. The limiting mechanism includes a limiting rod, a fixed plate, and a limiting block. The fixed plate is connected to the second fixed frame. A limiting hole is provided on the fixed plate. The limiting rod passes through the limiting hole and is connected to the limiting block. The limiting rod and the fixed plate are slidably connected through the limiting hole.

[0023] When stacking angle steel, it is necessary not only to ensure that the openings of the angle steel in the upper and lower adjacent layers are set in opposite directions, but also to ensure that the upper layer angle steel spans across the two sides of the lower adjacent angle steel. This requires the upper and lower layers of angle steel to maintain a certain distance in the horizontal direction. By adopting the above technical solution, the limiting block can limit the angle steel. By sliding the limiting rod, the position of the angle steel on the conveyor platform can be adjusted to ensure that the upper layer angle steel spans across the two sides of the lower adjacent angle steel. This helps to improve the stability of the angle steel stack, optimizes the step of horizontally moving and adjusting the position of the magnetic suction component, and improves the stacking efficiency.

[0024] Optionally, the limiting mechanism further includes a transmission assembly, which is connected to the limiting rod and can drive the limiting rod to slide. The transmission assembly includes a transmission shaft, a first fixed sleeve, and a second fixed sleeve. The transmission shaft is rotatably connected to the second fixed frame. The first fixed sleeve and the second fixed sleeve are both fixedly connected to the transmission shaft. The first fixed sleeve is hinged to the limiting rod, and the second fixed sleeve is hinged to a driving member.

[0025] By adopting the above technical solution, when it is necessary to adjust the placement position of the angle steel, the driving component is activated, which drives the second fixed sleeve to rotate. The second fixed sleeve drives the transmission shaft to rotate, which in turn drives the first fixed sleeve on the transmission shaft to rotate. Through the rotational movement of the first fixed sleeve, the limiting rod hinged to the first fixed sleeve moves along the length direction of the limiting hole, which is beneficial to adjusting the placement position of the angle steel and improving the stability of the angle steel stack.

[0026] Optionally, a lifting mechanism is provided on the transfer platform. The lifting mechanism includes a support frame, a limiting sleeve, and a lifting rod. The limiting sleeve is connected to the transfer platform, and the lifting rod passes through the limiting sleeve and is connected to the support frame.

[0027] By adopting the above technical solution, when the angle steel needs to be attracted, the support plate moves vertically upward, so that the support frame appropriately lifts the angle steel and brings it closer to the magnetic component, thereby enhancing the attraction force of the magnetic component. This optimizes the step where the magnetic component needs to move vertically downward a certain distance before it can attract the angle steel, which is beneficial to improving the efficiency of the magnetic component in attracting the angle steel.

[0028] Secondly, this application provides a palletizing method based on an automated multi-layer angle steel palletizing system, comprising the following steps:

[0029] S1. Start the conveyor chain so that the angle steel is transported along the conveyor frame to the limit stop;

[0030] S2. Rotate the magnetic suction component clockwise to move it directly under the angle steel group composed of multiple angle steels and activate the magnetic suction component to attract the angle steel group. Then, the magnetic suction component moves vertically upward to maintain a vertical distance between the magnetic suction component and the transmission frame.

[0031] S3. Start the drive unit to make the limit rod slide along the length of the limit hole to change the position of the limit block;

[0032] S4. Move the lifting rod vertically upward to lift the support frame and then move it to the angle steel group to be stacked.

[0033] S5. Reverse the magnetic attraction component to allow it to continue attracting the angle steel assembly lifted by the support frame.

[0034] By adopting the above technical solution, the magnetic suction component rotates back and forth to attract angle steel groups to achieve automatic stacking of angle steel, which helps to improve stacking efficiency.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. The magnetic suction component in this application can rotate around the mounting frame. When multiple angle steels are transported to the appropriate position on the conveyor platform via the conveyor chain, the truss trolley is activated to drive the suction mechanism to move vertically until the magnetic suction component is located at the lower end of the angle steel group formed by the multiple angle steels. The magnetic suction component is then activated to suction the multiple angle steels and lift them vertically upward to a certain height. At this time, the subsequent angle steel groups also move to the appropriate position. The magnetic suction component that has already suctioned a group of angle steels is rotated to continue suctioning the subsequent angle steels. By rotating the magnetic suction component back and forth to suction the angle steels, the angle steels are stacked. This method has a higher degree of automation and is conducive to improving work efficiency.

[0037] 2. The output shaft of this application is provided with circuit holes and air holes. The corresponding circuit lines can be connected to the external power supply system through the circuit holes, and the corresponding air lines can also be connected to the external air supply system through the air holes to ensure the normal operation of the magnetic attraction component. By opening circuit holes and air holes on the output shaft, the circuit and air path of the adsorption mechanism are highly integrated, which is conducive to optimizing the circuit and air path structure.

[0038] 3. In this application, a buffer mechanism is connected to the second fixed frame. When the magnetic suction component comes into contact with the transmission frame, the transmission frame rotates adaptively relative to the second fixed frame, and the elastic element contracts. When the magnetic suction component is removed, the contracted elastic element rebounds, causing the transmission frame to return to its initial state. This reduces the possibility of the magnetic suction component damaging the transmission frame and helps to improve the safety of the angle steel stacking system. Attached Figure Description

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0049] An automated multi-layer angle steel stacking system, referring to Figure 1 The system includes a transmission mechanism 1, a support mechanism 2, and an adsorption mechanism 3. The support mechanism 2 is connected to the transmission mechanism 1 and supports the transmission mechanism 1.

Furthermore, to improve the stability of the adsorption mechanism 3 in adsorbing the angle steel, an adsorption mechanism 3 is provided between each adjacent transmission mechanism 1 in this embodiment.

[0051] When the angle steel is conveyed to the stacking point by the conveyor chain 12, the conveyor mechanism 1 is moved to the lower end of the angle steel by the truss trolley, and then the magnetic suction assembly 33 is rotated half a turn. It should be noted that this... Figure 1 The magnetic suction component 33 is already in a state of rotating half a revolution around the mounting bracket 31. At this time, the limiting groove 321 opened on the limiting plate 32 corresponds to the several angle steels that are about to be attracted. Then, the magnetic suction component 33 is activated, and after firmly attracting the angle steels, the suction mechanism 3 is raised to a certain height and then the magnetic suction component 33 is rotated in the opposite direction to return the magnetic suction component 33 to its initial state. The height difference between the suction mechanism 3 and the transmission mechanism 1 is only required to ensure that the magnetic suction component 33 does not interfere with the transmission mechanism 1 when it drives the attracted angle steels to rotate synchronously.

Some of the wires in the circuit hole 33321 can pass through the stepped hole 33333 and connect to the control unit 332. It should be noted that the wires in this application are not shown.

[0065] Reference Figure 8 The output shaft 3332 is also provided with an air passage hole 33322. Specifically, the air passage hole 33322 is opened from one end sidewall of the output shaft 3332 and extends to the other end sidewall of the output shaft 3332. A vent pipe can be installed at the end of the air passage hole 33322 near the control unit 332 and connected to the control unit 332 through the vent pipe. It should be noted that the vent pipe is not shown in this application. Furthermore, the mounting sleeve 3331 is provided with a plurality of vent grooves 33312. As a preferred embodiment of this application, the number of vent grooves 33312 in this embodiment is 3. Ventilation slots 33312 are arranged around the mounting sleeve 3331 and evenly distributed between the two mounting slots 33311. Specifically, the depth of the middle mounting slot 33311 is greater than that of the other mounting slots 33311. An air supply hole 33313 is also provided on the inner wall of the mounting slot 33311. The air supply hole 33313 passes through the mounting sleeve 3331 and the fixed sleeve 3334 in sequence to supply air to the control unit 332. By opening the air passage hole 33322 and the circuit hole 33321 on the output shaft 3332, the circuit and air passage of the adsorption mechanism 3 are highly integrated.

[0066] This embodiment also discloses a palletizing method based on an automated multi-layer angle steel palletizing system, including the following steps:

[0067] S1. Start the transmission chain 12 so that the angle steel is transported along the transmission platform 11 to the limit stop 53;

[0068] S2. Rotate the magnetic suction component 33 clockwise to move the magnetic suction component 33 directly below the angle steel group composed of multiple angle steels and start the magnetic suction component 33 to attract the angle steel group. Then the magnetic suction component 33 moves vertically upward to maintain a vertical distance between the magnetic suction component 33 and the transmission frame 11.

[0069] S3. Start the drive unit 8 to make the limit rod 51 slide along the length direction of the limit hole 521 to change the position of the limit block 53.

[0070] S4. Move the lifting rod 63 vertically upward to lift the support frame 61 and then move it to the angle steel group to be stacked.

[0071] S5. Reverse the magnetic attraction component 33 so that the magnetic attraction component 33 continues to attract the angle steel group lifted by the support frame 61.

[0072] The implementation principle of this application embodiment is as follows: The transmission rod 13 is activated, causing the transmission chain 12 to rotate relative to the transmission platform 11. The angle steel located on the transmission platform 11 is moved to the limit stop 53 under the drive of the transmission chain 12. At this time, the adsorption mechanism 3 moves to the lower end of the angle steel under the drive of the truss trolley. At this time, the control unit 332 controls the drive unit 333 to rotate the magnetic adsorption unit 331, so that each limit groove 321 on the limit plate 32 is set to correspond one-to-one with multiple angle steels. At this time, the control unit 332 activates the magnetic adsorption unit 331, so that the angle steel is adsorbed. Then, the truss trolley drives the adsorption mechanism 3, which has adsorbed a group of angle steels, to rise to a certain height.

[0073] As the adsorption mechanism 3 rises, the drive component 8 connected to the transmission shaft 541 starts and drives the limit rod 51 to slide, thereby changing the position of the limit block 53. This ensures that the angle steel to be adsorbed and the angle steel being adsorbed are kept at a certain distance in the horizontal direction, so as to ensure that the upper angle steel spans on both sides of the lower adjacent angle steel. At this time, the control unit 332 controls the drive unit 333 to rotate the magnetic suction unit 331 in the opposite direction, so that the openings of the already adsorbed angle steel and the angle steel to be adsorbed are opposite. The support mechanism 2 is started. Driven by the drive component 8, the angle steel on the support frame 61 rises to a certain height and is adsorbed by the magnetic suction unit 331, thereby realizing the stacking of angle steel.
