Description

Technical Field

[0001] This invention relates to the field of steel section stacking technology, and specifically discloses an automatic stacking system for cap-shaped cold-formed steel sections. Background Technology

[0002] Hat-shaped cold-formed steel sections are mainly used in railway vehicle carriages, exhibiting excellent performance in atmospheric corrosion resistance, high strength, low-temperature impact toughness, and weldability. However, due to their non-planar or asymmetrical structure, the manufacturing process often results in "two-sided tilting," making automated online stacking impossible. Therefore, current production processes rely on manual operation and overhead cranes for stacking one section at a time. Furthermore, once a certain production volume is reached, production must be stopped for on-site cleanup, further hindering continuous production, leading to decreased efficiency and increased labor costs. Therefore, there is an urgent need to develop an automated stacking system for hat-shaped cold-formed steel sections to improve their stacking efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic palletizing system for cap-shaped cold-formed steel, which has a simple structure, fast and precise movement, high efficiency, and solves the problem of high-precision automatic palletizing and packaging of various types and specifications of steel, which is of great significance to actual production.

The output end of the second power source is connected to a crank-connecting rod mechanism connected to the first drive module. The second power source is capable of driving the first drive module to rotate 90° around the Y-axis.

[0007] In a preferred embodiment of the present invention, the palletizing platform is provided with multiple sets of adjustable transverse modules arranged at intervals along the Y-axis. Each set of adjustable transverse modules includes two adjustable transverse units arranged symmetrically relative to the X-axis. Each adjustable transverse unit includes an adjusting cylinder extending along the Y-axis and a support block connected to the piston rod end of the adjusting cylinder.

The narrow end of the top rod portion is provided with a rounded corner, the center of which is tangent to the rounded corner at the bottom of the cap-shaped cold-formed steel and the waist height connection.

[0010] In a preferred embodiment of the present invention, the gantry is provided with a movable unit that can be translated along the X-axis, and the movable unit is provided with a plurality of cylinders arranged at intervals along the Y-axis and extending along the Z-axis, and the piston rod end of each cylinder is connected to the lifting mounting frame.

[0011] In a preferred embodiment of the present invention, a first conveying roller conveyor extending along the Y-axis is provided upstream of the first conveying platform, and a first steel-pulling machine is provided between the first conveying roller conveyor and the first conveying platform.

[0012] In a preferred embodiment of the present invention, the ends of the first conveying roller and the second conveying roller are provided with stops for limiting the cap-shaped cold-formed steel along the Y direction.

[0013] The beneficial effects of this invention are as follows: This invention features a simple structure, rapid and precise movement, and high efficiency. It solves the problem of high-precision automatic palletizing and packaging of various types and specifications of steel profiles, which is of great significance to actual production. Specifically, this invention solves the problem of consistent opening directions for cap-shaped cold-formed steel products before automatic palletizing; it enables the palletizing of cap-shaped cold-formed steel from multiple sides; and it solves the problem of instability and collapse after palletizing cap-shaped cold-formed steel on both sides. This invention can meet the palletizing needs of cap-shaped cold-formed steel of different sizes and achieve switching between different methods. Furthermore, all conveyor frame devices of this invention are equipped with conveying components and anti-scratch chains. Furthermore, the movable stop head of this invention is fixed at the end of the conveyor frame, and the position of the steel profile on the conveyor frame can be determined by replacing nylon baffles of different thicknesses.

To ensure the right-side chamfer is R10, preventing surface scratches after the product is lifted, and with the top rod protruding at a height greater than 1.5 times the small side of the cap-shaped steel, it ensures rotation of more than 45° around the small side of the cap-shaped steel. Furthermore, this invention proposes a stacking device capable of flipping all four sides of the cap-shaped cold-formed steel. It consists of a first drive module and a second drive module. The first drive module can flip the cap-shaped cold-formed steel to three states: A-side, B-side, and C-side. The second drive module is used to flip the cap-shaped cold-formed steel located on side B to side D. Therefore, all four sides (A, B, C, and D) can be flipped, allowing the product to be accurately stacked in the corresponding positions. This also solves the safety hazard caused by direct contact between the product's right-angled edge and the packing strap, resulting in strap breakage. It is more stable during lifting and transportation, and can automatically stack over 90% of irregularly shaped cold-formed steel for customers, offering greater flexibility in package shape and meeting various customer packaging needs.

A second steel-pulling machine 8 is set at the intersection of the first conveyor frame 5 and the second conveyor roller conveyor 12. A third steel-pulling machine 13 is set at the intersection of the second conveyor frame 17 and the second conveyor roller conveyor 12. A stacking device 20 is set between the stacking platform 23 and the second conveyor frame 17. A cap-shaped cold-formed steel section with an inclined opening facing upwards and a contact limit is set at one end of the first conveyor frame 5 near the second conveyor roller conveyor 12. The movable stop 7 on the edge end face, and the crossbeam of the second steel feeding machine 8 are equipped with a movable push rod 9 for contacting and pushing the upper edge end face of the cap-shaped cold-formed steel with the opening facing obliquely upward. The movable push rod 9 is located upstream of the movable stop 7. The movable push rod 9 and the movable stop 7 work together to rotate the cap-shaped cold-formed steel with the opening facing obliquely upward by 45° to form a horizontally arranged cap-shaped cold-formed steel with the opening facing directly downward and push it to the conveyor roller 2. Specifically, its working principle is the same as the working principle of flipping C-shaped steel in CN111824783A.

[0028] Preferably, the palletizing device 20 includes a gantry frame 201, on which a lifting mounting frame 202 is arranged that can translate along the X-axis, lift along the Z-axis, and extend along the Y-axis. The lifting mounting frame 202 is provided with a plurality of electromagnet rotating mechanisms 19 arranged at intervals along the X-axis. Preferably, each electromagnet rotating mechanism 19 includes an electromagnet for attracting the upper or lower end face of a horizontally arranged, open-facing, cap-shaped cold-formed steel section, and a rotating drive unit for driving the electromagnet to rotate around the X-axis.

[0029] Preferably, the rotary drive unit comprises a first drive module and a second drive module. The drive module includes a first power source 19.1 capable of rotating around the Y-axis, a rotating shaft 19.2 extending along the Y-axis and connected to the output end of the first power source 19.1, and an electromagnet 19.3 connected to the rotating shaft 19.2. The first power source 19.1 is capable of rotating 90° or 180° around the Y-axis. The second drive module includes a second power source 19.4 capable of rotating around the Y-axis. The output end of the second power source 19.4 is connected to a crank-connecting rod mechanism connected to the first drive module. The second power source 19.4 can drive the first drive module to rotate 90° around the Y-axis.

[0030] Preferably, the palletizing platform 23 is provided with multiple sets of adjustable transverse modules 21 arranged at intervals along the Y-axis. Each set of adjustable transverse modules 21 includes two adjustable transverse units arranged symmetrically relative to the X-axis. Each adjustable transverse unit includes an adjusting cylinder 21.1 extending along the Y-axis and a support block 21.2 connected to the piston rod end of the adjusting cylinder 21.1. The upper end surface of the support block 21.2 is an inclined surface.

[0031] Preferably, the movable stop 7 includes an L-shaped base 7.1 and a nylon baffle 7.3, which are connected by hexagon socket head cap screws 7.2. The base 7.1 is welded to the end sprocket of the first conveyor frame 5.

[0032] Preferably, the movable top rod 9 includes an L-shaped top rod portion, on which two waist-shaped holes are provided extending along the Z-axis. The two waist-shaped holes are symmetrically arranged along the Z-axis. The narrow end of the top rod portion is provided with a rounded corner, the center of which is tangent to the rounded corner at the bottom of the cap-shaped cold-formed steel and the waist height connection.

[0033] Preferably, the gantry 201 is provided with a movable unit that can be translated along the X-axis. The movable unit is provided with a plurality of cylinders that are spaced apart along the Y-axis and extend along the Z-axis. The piston rod end of each cylinder is connected to a lifting mounting frame 202.

[0034] Preferably, a first conveying roller conveyor 1 extending along the Y-axis is provided upstream of the first conveying platform 5, and a first steel-pulling machine 2 is provided between the first conveying roller conveyor 1 and the first conveying platform 5.

[0035] Preferably, the ends of the first conveyor roller 1 and the second conveyor roller 12 are provided with stops for limiting the cap-shaped cold-formed steel along the Y direction.

[0036] Preferably, the present invention comprises a first conveyor roller 1, a first steel-pulling machine 2, a transmission motor reducer 3, a first stop 4, a first conveyor frame 5, a first conveyor frame transmission motor reducer 6, a movable stop 7, a second steel-pulling machine 8, a movable top rod 9, a second transmission motor reducer 10, a second conveyor roller 11, a second conveyor roller 12, a third steel-pulling machine 13, a third steel-pulling machine transmission motor reducer 14, a second stop 15, a head-aligning machine 16, a second conveyor frame 17, a second conveyor frame motor reducer 18, an electromagnet rotating mechanism 19, a stacking device 20, an adjusting transverse module 21, an adjusting guard roller 22, a stacking platform 23, and a stacking platform transmission motor reducer 24. The air source for the cylinder is provided by an external air pump.

[0037] Preferably, the base 7.1 of the movable stop 7 is installed at the sprocket of the first conveyor frame 5. After installation, it is directly welded. The nylon baffle 7.3 is installed on the base with hexagon socket head cap bolts 7.2. The mounting holes are through holes. The nylon baffle is installed in advance according to the product size to ensure that the center line contact point of the movable top rod 9 is tangent to the bottom R and waist height of the cap-shaped cold-formed steel. When the second steel-turning machine 8 is working, the top rod contacts the bottom R of the cap-shaped cold-formed steel in advance. During the upward movement of the top rod, with the small edge vertex of the cap-shaped cold-formed steel as the center, the bottom of the product is lifted and rotated more than 45° by the lifting top rod. When the small edge contacts the product, the inertia of the steel-turning machine and the product's own weight are used to achieve the product flipping effect. Note: The thickness of the baffle is determined according to the product size (height).

[0038] Preferably, the palletizing device 20 adjusts its control program according to the product packaging requirements. Under normal circumstances, the electromagnet remains on side B. During operation, the first power source 19.1 drives the rotating shaft 19.2 to rotate 90° or 180°, causing the electromagnet to rotate to side A, B, or C. The second power source 19.4 drives the pull rod to rotate the electromagnet 90° to side D, thus enabling palletizing on all four sides. Both the first power source 19.1 and the second power source 19.4 include servo motors and reducers. Understandably, the stacking device 20 can adsorb the upper or lower end face of the cap-shaped cold-formed steel. After adsorption, the cap-shaped cold-formed steel in the air is rotated by the first power source 19.1 or the second power source 19.4 so that its bottom end face is parallel to surface A, B, C or D. When the top end face of the cap-shaped cold-formed steel is adsorbed, the opening of the cap-shaped cold-formed steel faces upward when it is parallel to surface A, downward when it is parallel to surface B, right when it is parallel to surface C, and left when it is parallel to surface D.

[0039] Preferably, due to the asymmetrical nature of the cap-shaped cold-formed steel, some of it may be stacked sideways during stacking, which can easily lead to collapse. A movable slider is used to support the suspended parts of the cap-shaped cold-formed steel. When the cap-shaped cold-formed steel is stacked to the side according to the control program, the adjusting cylinder 21.1 pushes the flange and support block 21.2 to the designated position according to the program instructions. The upper surface of the support block 21.2 is inclined to support the suspended parts of the product. After packaging is completed, it automatically returns to its original position. Note: The cylinder stroke is 0-140 mm, and the air pressure is adjusted according to usage requirements.

[0040] Preferably, the specific palletizing process of the present invention is as follows:

[0041] Turn on the control panel power, input and confirm product parameters and packaging requirements, press the automatic mode button on the control panel, and after the product is cut to the required length, it is conveyed to the first stop 4 via the first conveyor roller 1. After a 1-second delay, the first steel feeder 2 operates, turning the product to the first conveyor frame 5. The first conveyor frame 1 transports the product to the movable stop 7. After a 1-second delay, the second steel feeder 8 operates, using the apex of the small side of the cap-shaped cold-formed steel as the center, and lifts the bottom of the product by more than 45° using the lifting rod, so that the product is turned onto the second conveyor roller 12 with the opening facing down. The product is then transported to the second stop 15. After a 1-second delay, the third steel feeder 13 operates, turning the product to the second conveyor frame 17. The second conveyor frame 2 transports the product to the end... At the head baffle, the electromagnet rotating mechanism 19 operates, adsorbing and lifting products according to packaging requirements. The palletizing device 20 is activated, moving to the palletizing platform 23 to place products according to packaging requirements and control program. When the 9th product is placed, the electromagnet rotating mechanism 19 rotates to the D side according to system instructions. After a 0.5s delay, the inner side of the adjusting transverse module 21 starts to operate, and the slider is pushed to the adjustment stop point. When the 10th product is placed, the electromagnet rotating mechanism 19 rotates to the C side according to system instructions. After a 0.5s delay, the outer side of the adjusting transverse module 21 starts to operate, and the slider is pushed to the adjustment stop point. After that, the products are stacked in the same way as the 1-8 products described above. After meeting the packaging requirements, they are transported to the next process via the packaging roller conveyor.

[0042] The beneficial effects of this invention are as follows:

[0043] 1) Based on the traditional automatic palletizing method (the electromagnet cannot rotate and is fixed on side B), a new type of electromagnet rotating mechanism is designed. Using servo motors, rotating brackets, rotating shafts and other components, the mechanism is controlled by a program to achieve four-sided rotating palletizing. This solves the problem that irregular cold-formed steel cannot be automatically palletized in online production and meets the requirements for online production palletizing of more than 90% of irregular cold-formed steel, such as channel steel, continuous steel and other series of products.

[0044] 2) The design of movable baffles and lifting rod devices can adjust the contact position according to the product size, and use the product's own weight and inertia to achieve the flipping effect, thus solving the problem of inconsistent opening directions of irregular cold-formed steel.

[0045] 3) For special products and packaging requirements, a pneumatic moving slider device was designed to increase the contact area between the product and the equipment, improve the stability of the product after stacking, and solve the problem of products collapsing after being stacked vertically.

[0046] 4) For different product packaging structures, the servo system accurately positions and performs high-precision product flipping control to achieve stacking at different angles and rapid switching.

[0047] 5) After the automatic palletizing equipment was put into use, the production efficiency increased by about 30%. In 2022, the output of our special-shaped cold-formed steel unit increased from 14,000 tons to 18,000 tons, and the number of palletizing and packaging personnel was reduced from 5 to 3. The labor intensity of workers was significantly reduced, while the production of special-shaped cold-formed steel was increased, and the market competitiveness was improved.

[0048] The technical solution of the present invention has been further described in detail with reference to the accompanying drawings and by way of listing some optional embodiments. These embodiments provide an innovative solution to the problems existing in the production process of cap-shaped cold-formed steel. In these embodiments, it can be seen that the design of the present invention takes into account the non-planar and asymmetric characteristics of cap-shaped cold-formed steel, as well as factors such as automation, stability, and adjustability in the production process. The following further supplements and explains the key details provided:

[0049] Electromagnet Rotation Mechanism Design: Introducing an electromagnet rotation mechanism into the palletizing device 20 is one of the innovations of this invention. This mechanism allows the electromagnet to rotate between multiple surfaces, enabling the cap-shaped cold-formed steel to be placed in different orientations to meet various packaging requirements. This mechanism involves the coordinated operation of components such as a servo motor, rotating support, and rotating shaft. Program control enables the electromagnet to switch between surfaces A, B, C, and D, thereby solving the problem of asymmetrical product palletizing.

[0050] Movable stop and movable top rod design: This invention addresses the asymmetrical shape of cap-shaped cold-formed steel by designing a movable stop and movable top rod device. During product transfer, these devices can flexibly contact and apply force to the product according to changes in its size and shape, thereby enabling product flipping and orientation adjustment. This design ensures consistent stacking results even when products have different opening directions, improving production stability and efficiency.

[0051] Adjustable transverse movement module and cylinder design: To address special product and packaging requirements, this invention introduces an adjustable transverse movement module and cylinder device. These modules can support the suspended portion of the product during palletizing, thereby improving the stability and safety of the product during palletizing. The operation of the cylinders allows for fine-tuning of the product position to accommodate the palletizing needs of products of different sizes and shapes.

[0052] Based on the product's appearance and execution standards, this invention employs professional analysis software and data analysis. Before production, the movable stop nylon plate is replaced, and the height of the lifting rod, the opening and closing degree of the guard roller, and the stroke of the pneumatic slider are adjusted. The stacking sequence of each product is designed according to the package type, and the stacking requirements fully consider the feasibility of operation. The control system parameters and the rotation direction of the electromagnet are set to adsorb the product surface in a reasonable and reliable manner, ensuring that the contact area between the magnet and the product is maximized. Then, the driver is instructed to control the servo motor to work, so that the robotic arm can reach different positions and angles to realize various stacking methods and improve transportation stability.

[0053] The operation process and steps of this invention 2 include: starting the power supply to put the automatic stacking equipment for irregularly shaped cold-formed steel in standby mode; checking whether the control program and mechanical equipment are normal; switching the control program to manual mode; and starting production once everything is ready. After the product is formed, it is cut to the standard length and transported to the end of the first roller conveyor. It is then transferred to the first conveyor frame by the first steel-pulling machine. Personnel check the product quality at the first conveyor frame to ensure it meets the standards. If the product is found to be defective, the second steel-pulling machine is used for two consecutive operations. The product then enters the work-in-process collection tank (not shown in the figure). Once the product is qualified, the control program is set to automatic. The product is transferred from the second steel feeder to the second conveyor roller to enter the normal stacking process. When the product reaches the second stop, it is transferred from the third steel feeder to the collection conveyor frame (second conveyor frame). After being transported to the end of the frame, the system controls the electromagnet rotation mechanism to attract the designated surface of the product. The product is then moved to the designated position on the stacking roller by the electromagnet lateral movement device (not shown in the single equipment diagram). If there are no special packaging requirements (vertical packaging), the pneumatic slider stroke can be adjusted to 0. After the number of packages is met, the product is transported to the next process via the packaging roller.

[0054] In summary, through the detailed description of the embodiments, the technical solution and solutions of the present invention have been clearly demonstrated, which can effectively solve the problems existing in the production process of cap-shaped cold-formed steel, improve production efficiency and quality, reduce production costs, and provide an innovative method for the production of cap-shaped cold-formed steel. At the same time, the innovation of the present invention and the substantial benefits it brings in practical applications are emphasized, further highlighting its value in this field.

[0055] Furthermore, the steel-drawing machine, not elaborated in this invention, belongs to existing technology. Its main functions include: 1. Positioning and arrangement: The steel-drawing machine can automatically position and arrange steel profiles into the required stacking pattern. This can include accurately placing the steel profiles according to their size, length, shape, and other characteristics to ensure the stability and compactness of the stack. 2. Layered stacking: The steel-drawing machine can stack steel profiles of different sizes and specifications in layers, allowing each layer of steel profiles to nest with each other, thereby maximizing the use of stack space and reducing waste. 3. Automatic stacking: Once the steel profiles are accurately arranged and positioned, the steel-drawing machine can automatically perform the stacking operation. It can control the gripping and placement of the steel profiles to ensure the stability and balance of each stack. 4. Saving manpower and time: The automation function of the steel-drawing machine can greatly save manpower and time. Compared with manual stacking, the steel-drawing machine can complete the stacking process faster and more accurately, reducing production costs and improving production efficiency. 5. Reducing errors: Since the steel-drawing machine operates based on a preset program, it can reduce errors caused by human factors, such as unstable stacking and positional deviation. The role of the steel-drawing machine in the automatic steel-section stacking system is to automate the processing, positioning, arrangement, and stacking of steel materials, thereby improving production efficiency, reducing costs, and ensuring the stability and accuracy of stacking. The innovation of this invention lies in the installation of a movable push rod 9 on the crossbeam of the second steel-drawing machine 8. This movable push rod 9 is positioned upstream of the movable stop 7. Working in tandem, the movable push rod 9 and the movable stop 7 rotate the upward-facing cap-shaped cold-formed steel by 45° to form a horizontally arranged cap-shaped cold-formed steel with its opening facing directly downwards, and then push it onto the conveyor roller conveyor 2. This solves the problem of consistent opening direction for irregularly shaped cold-formed steel products before automatic stacking, laying the foundation for convenient control of subsequent stacking.

[0056] It will be readily understood by those skilled in the art that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, combinations, substitutions, improvements, etc., made under the spirit and principles of the present invention are included within the protection scope of the present invention.
