Description

Technical Field

[0001] The present application relates to the technical field of angle steel processing, and in particular to an automatic stacking and packaging device for angle steel and an angle steel production line using the device. Background Art

[0002] Angle steel, commonly known as angle iron, is a long steel bar with two perpendicular sides forming an angle. There are two types of angle steel: equal-leg angle steel and unequal-leg angle steel. Equal-leg angle steel has two sides of equal width, while unequal-leg angle steel has two sides of unequal width. Angle steel is widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

[0003] In related technologies, a platform is installed at one end of the drying chamber where the angle steel is discharged. After undergoing a series of production processes and drying, it is moved out of the drying chamber and onto the platform. A transmission assembly is installed within the platform to move the angle steel to a position for subsequent stacking and packaging. At least two operators then work together, one standing at one end of the angle steel, and the other working together to flip and stack the angle steel, and then package the stacked angle steel.

[0004] However, since the length of each angle steel produced is relatively long and heavy, manual flipping and stacking is time-consuming and labor-intensive, which not only increases the workload of operators, but also leads to a low level of automation in the production and processing of angle steel. Summary of the Invention

[0005] In order to improve the problem that manual flipping and stacking is time-consuming and labor-intensive, increases the workload of operators, and also leads to a low level of automation in the production and processing of angle steels, the present application provides an automatic stacking and packaging device for angle steels and an angle steel production line using the device.

[0006] In the first aspect, the present application provides an automatic angle steel stacking and packaging device that adopts the following technical solutions:

[0007] An automatic stacking and packaging device for angle steel comprises a transfer device and a stacking device provided on a side of a placement platform away from a drying chamber, the transfer device comprising a transmission assembly and a conveying assembly, the transmission assembly being provided below the placement platform and used to drive the workpiece to move along its width direction on the placement platform, the conveying assembly comprising a conveying frame and a conveyor belt, the conveying frame being provided on a side of the placement platform away from the drying chamber, the moving direction of the conveyor belt being consistent with the length direction of the workpiece, and the conveyor belt being used to convey the workpiece along the length direction of the workpiece;

[0008] The stacking device includes a baling frame, a stacking assembly and a stacking assembly. The baling frame is arranged at one end of the conveying frame along the length direction of the workpiece. The stacking assembly is arranged on the baling frame. The stacking assembly is used to stack multiple workpieces in sequence to form a workpiece group. The stacking assembly is used to arrange multiple workpiece groups in sequence.

[0009] By adopting the above technical solution, the angle steel is dried in the drying room after a series of processing and moved to the placement platform. Multiple workpieces are moved out of the drying room in turn along their own width direction, and then moved to the conveyor belt in turn. The conveyor belt moves the workpieces in turn to the packaging rack, and then the stacking component stacks the multiple workpieces in turn. According to the PLC preset counting program, the number in each workpiece group is consistent. After the current workpiece is stacked to form a workpiece group, the stacking component carries the workpiece group to move; the stacking component continues to run to form the next workpiece group, saving the process of manually moving the stacked workpieces and effectively improving the level of automated processing of workpiece stacking and packaging.

[0010] Preferably, the cross-section of the conveyor belt is V-shaped.

[0011] By adopting the above technical solution, the workpiece is moved from the placement platform to the conveyor belt, and under the action of its own weight, it enters the conveyor belt in a V-shaped state. Then the conveyor belt allows the workpiece to move in a V-shaped state to the packaging machine frame, facilitating subsequent stacking.

[0012] Preferably, the stacking assembly includes a stacking frame, a stacking belt and a stacking rod. The stacking frame is arranged in the packaging machine frame, and the stacking belt is movably arranged on the stacking frame. There are a plurality of stacking rods, and the plurality of stacking rods are evenly arranged on the stacking belt. A storage space is formed between each two adjacent stacking rods, and the storage space is used to store workpieces.

[0013] By adopting the above technical solution, the workpieces are transferred to the storage space one by one via the conveyor belt, and the two adjacent stacking poles limit and position the workpieces, so that the workpieces are stacked in sequence to form workpiece groups; then the stacking belt moves, driving the workpiece groups to move synchronously, making way for the stacking of the next group of workpieces, thereby realizing automated stacking arrangement.

[0014] Preferably, the stacking assembly includes a guide wheel and a separator, the guide wheel is rotatably arranged on the baling machine frame, and a magnetic block is provided in the guide wheel, the conveyor belt conveys the workpiece so that the guide wheel contacts the workpiece, and the magnetic block and the workpiece are adsorbed on each other, and the separator is arranged on the baling machine frame, and the separator is used to drive the workpiece to separate from the guide wheel, so that the workpiece moves into the storage space.

[0015] By adopting the above technical solution, the conveyor belt drives the workpiece to move toward the packaging machine frame. When the workpiece contacts the guide wheel, the workpiece and the guide wheel always maintain contact under the magnetic action of the magnetic block. As the conveyor belt is transported, the workpiece continues to move forward at a uniform speed, driving the guide wheel to rotate accordingly, reducing the friction generated between the guide wheel and the workpiece; when the workpiece moves into place, the separator drives the workpiece to separate from the guide wheel, so that the workpiece automatically enters the storage space, which can not only realize the directional movement of the workpiece, but also greatly reduce the friction during the movement of the workpiece, thereby improving the automated processing efficiency of stacking the workpieces.

[0016] Preferably, the stacking assembly also includes a stacking drive source, a stacking shaft and a stacking ball. The stacking drive source is provided on the stacking frame, the stacking shaft is rotatably connected to the stacking frame, the stacking drive source is used to drive the stacking shaft to rotate, the stacking belt is wound around the stacking shaft, a plurality of stacking balls are provided and are evenly connected to the stacking belt, the stacking rod is fixedly connected to the side of the stacking ball away from the stacking belt, the stacking balls correspond to the stacking rods one by one, and the stacking balls and the stacking rods are both made of rubber.

[0017] By adopting the above technical solution, according to the preset PLC program, the separator continuously drives the workpiece to fall into the storage space. When falling, the workpiece collides with the stacking ball and the stacking rod, and the stacking ball buffers the workpiece; after the number of the current workpiece group meets the preset value, the stacking drive source drives the stacking shaft to rotate, and the stacking shaft rotates to drive the stacking belt to move, so that the stacking belt carries the stacked workpiece group to move, making way for the subsequent formation of the next workpiece group, facilitating the concentrated formation of multiple workpiece groups, and allowing multiple workpiece groups to be arranged in sequence for centralized packaging, thereby further improving the level of automation.

[0018] Preferably, the separation component includes a separation cylinder and a pushing block, the separation cylinder is fixedly connected to the baling machine frame, the pushing block is arranged at the end of the piston rod of the separation cylinder, the separation cylinder drives the pushing block to move, and the pushing block separates the workpiece from the guide wheel.

[0019] By adopting the above technical solution, when the workpiece moves into position with the conveyor belt, the separation cylinder starts to drive the push block to move, the push block abuts against the workpiece, and separates the workpiece from the guide wheel, thereby realizing the automatic falling and stacking of the workpiece.

[0020] Preferably, a limit plate is provided at one end of the packaging machine frame away from the conveying frame, and a pressure sensor is provided on the limit plate. The pressure sensor is electrically connected to the separation cylinder, and the pressure sensor is used to transmit a signal to the separation cylinder.

[0021] By adopting the above technical solution, the workpiece moves with the conveyor belt. When one end of the workpiece abuts against the limit plate, the workpiece moves into place. After the pressure sensor on the limit plate detects the pressure, it sends a signal to the separation cylinder. After receiving the signal, the separation cylinder starts and drives the push block to extend and move.

[0022] Preferably, it also includes a grinding assembly, which includes a grinding frame, a grinding shaft and a grinding wheel. The grinding frame is arranged between the conveying frame and the packaging machine frame, the grinding shaft is rotatably connected to the grinding frame, and the grinding wheel is rotatably connected to the grinding shaft. The axis of the grinding shaft is parallel to the axis of the guide wheel.

[0023] By adopting the above technical solution, after the workpiece moves onto the conveyor belt, the conveyor belt drives the workpiece along the length direction of the workpiece toward the packaging machine frame. During the movement, the workpiece passes through the grinding wheel, and the grinding wheel contacts the workpiece. As the workpiece moves, the grinding wheel further grinds and polishes the surface of the workpiece, which is beneficial to improving the quality of the workpiece after processing.

[0024] Preferably, the transfer device also includes a flipping assembly, which includes a bracket, a flipping drive source and a flipping rod. The bracket is arranged on the placement platform, and the flipping drive source is arranged on the bracket. The length direction of the flipping rod is in the same direction as the length direction of the workpiece. The flipping drive source is used to drive the flipping rod to move up and down relative to the placement platform. When the flipping rod descends relative to the placement platform, the flipping rod is against the workpiece, causing the workpiece to flip.

[0025] By adopting the above technical solution, when the workpiece moves from the drying chamber to the placement platform, one side of the workpiece is in contact with the placement platform and moves under the drive of the transmission component, and the other side is located on the side close to the drying chamber. When the workpiece moves to abut against the flip rod, the workpiece is flipped under the abutment of the flip rod, that is, one side is in contact with the placement platform and the other side is located on the side close to the conveyor belt; after the workpiece is flipped, it continues to move, that is, when the workpiece enters the conveyor belt, it is arranged on the conveyor belt in a V shape under the action of its own weight. The cooperation between the flip assembly and the conveyor belt facilitates the subsequent automatic stacking and packaging of the workpieces.

[0026] Preferably, an angle steel production line using any of the above-mentioned angle steel automatic stacking and packaging equipment comprises the following steps:

[0027] Grinding: Grind the bent workpiece to remove surface burrs;

[0028] Galvanizing: The surface of the polished workpiece is galvanized;

[0029] Cooling: After galvanizing is completed, the workpiece is cooled;

[0030] Passivation: Passivate the workpiece after cooling;

[0031] Drying: Dry the workpiece after passivation;

[0032] Stacking: Move and automatically stack the dried workpieces to achieve packaging.

[0033] By adopting the above technical solution, the production and processing of the entire angle steel are combined into one production line. After the basic grinding and deburring, the angle steel is subjected to surface galvanizing treatment, which can effectively improve the corrosion resistance and durability of the angle steel. After galvanizing, the angle steel is directly cooled to solidify the zinc liquid attached to the surface of the angle steel and better bond with the angle steel. The angle steel is then directly transported to the passivation treatment, and the active ions on the surface of the angle steel are removed by a chemical passivation method, thereby reducing the possibility of rusting of the angle steel during later use and increasing the service life of the angle steel. After passivation, the angle steel is further dried to complete the entire surface processing process of the angle steel, effectively improving the automation level of angle steel production and at the same time helping to further improve processing efficiency.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. After the angle steel is processed and dried in the drying chamber, multiple workpieces are moved out of the drying chamber in sequence along their width direction and then moved to the conveyor belt in sequence. The conveyor belt moves the workpieces in sequence to the packaging rack, and then the stacking component stacks the multiple workpieces in sequence. According to the PLC preset counting program, the number of workpieces in each group is consistent. After the current workpieces are stacked to form a workpiece group, the stacking component carries the workpiece group and moves; the stacking component continues to operate to form the next workpiece group, saving the process of manually moving the stacked workpieces and effectively improving the level of automation of workpiece stacking and packaging.

[0036] 2. Through the setting of the separation piece, the limit plate and the pressure sensor, the workpiece maintains contact with the guide wheel. When the workpiece moves to abut the limit plate, the pressure sensor cooperates with the separation cylinder to drive the push block to move, and the push block pushes the workpiece to separate from the guide wheel, so that the workpiece naturally falls into the storage space.

[0042] The following is combined with Figure 1-4 This application is described in further detail.

[0043] The embodiment of the present application discloses an automatic stacking and packaging device for angle steels, such as Figure 1 As shown, the apparatus includes a transfer device 2 and a stacking device 3, which are arranged on the side of the placement platform 1 away from the drying chamber 9. The transfer device 2 is used to further transfer the workpieces 5 removed from the drying chamber 9 to achieve subsequent automatic stacking and packaging of the workpieces 5. The stacking device 3 is used to automatically stack the workpieces 5, reducing manual operations and further improving the automation level of angle steel processing.

[0044] like Figure 1 and 2 As shown, the transfer device 2 includes a transmission assembly 21, which is disposed below the placement platform 1. The transmission assembly 21 is used to drive the workpiece 5 to move along its width on the placement platform 1. The transmission assembly 21 includes a transmission motor 211, a transmission shaft 212, and a transmission chain 213 (for clarity, the transmission chain 213 is illustrated as a belt in the figure). The transmission motor 211 is fixedly connected to one side of the placement platform 1, the transmission shaft 212 is rotatably connected to the placement platform 1, and the transmission chain 213 is wound around the transmission shaft 212. The output shaft of the transmission motor 211 is fixedly connected to the transmission shaft 212. When the transmission motor 211 is in operation, it drives the transmission shaft 212 to rotate relative to the placement platform 1. The transmission shaft 212 drives the transmission chain 213 to move along the width of the workpiece 5. The workpiece 5 is located on the transmission chain 213 and moves toward the side away from the drying chamber 9 along with the transmission chain 213.

[0045] like Figure 2 and 3 As shown, the transfer device 2 also includes a flip assembly 22, which includes a bracket 221, a flip drive source, and a flip rod 223. The bracket 221 is fixedly connected to the placement platform 1. The flip drive source is a flip cylinder 222, which is fixedly connected to the bracket 221. Two flip cylinders 222 are provided, and the two flip cylinders 222 are stacked and located on either side of the placement platform 1. The length direction of the flip rod 223 is the same as the length direction of the workpiece 5, and the piston rods of the two flip cylinders 222 are fixedly connected to the ends of the flip rod 223.

[0046] like Figure 1 、 3 As shown in Figures 4 and 5, the workpiece 5 includes a first equilateral side 51 and a second equilateral side 52, and the angle between the first equilateral side 51 and the second equilateral side 52 is less than or equal to ninety degrees. According to the angle steel processing technology, when the workpiece 5 is removed from the drying chamber 9, the first equilateral side 51 is attached to the table surface of the placement platform 1, and the second equilateral side 52 is located on the side of the first equilateral side 51 close to the drying chamber 9. According to the model of the workpiece 5 of different specifications, the distance between the flip rod 223 and the table surface of the placement platform 1 is adjusted and preset. When the flip cylinder 222 is in operation, the flip cylinder 222 drives the piston rod to extend, that is, the piston rod of the flip cylinder 222 drives the flip rod 223 to move up and down relative to the placement platform 1. When the transmission assembly 21 drives the workpiece 5 to move along the placement platform 1, the second equilateral side 52 of the workpiece 5 abuts against the flip rod 223. Under the cooperation of the abutment of the flip rod 223 and the movement of the transmission assembly 21, the workpiece 5 is flipped, and the second equilateral side 52 is attached to the placement platform 1. The first equilateral side 51 is located on the side of the second equilateral side 52 away from the drying chamber 9.

[0047] like Figure 2 As shown, the transfer device 2 also includes a conveying assembly 23, which includes a conveying frame 231 and a conveyor belt 232. The conveying frame 231 is located on the side of the placement platform 1 away from the drying chamber 9. A conveying motor 233 is fixedly connected to the conveying frame 231. The movement direction of the conveyor belt 232 is consistent with the length direction of the workpiece 5. The conveying motor 233 is used to drive the conveyor belt 232 to move, and the conveyor belt 232 is used to convey the workpiece 5 along the length direction of the workpiece 5. The cross-sectional profile of the conveyor belt 232 is V-shaped. After the workpiece 5 is flipped by the flipping assembly 22, it continues to move along the placement platform 1 under the transmission action of the transmission assembly 21. When it moves to contact the conveying frame 231, the workpiece 5 falls onto the conveyor belt 232 under the action of its own weight. The V-shaped profile of the conveyor belt 232 is compatible with the workpiece 5, allowing the workpiece 5 to move stably in a V-shape.

[0048] like Figure 2As shown, the stacking device 3 includes a baling frame 31, a stacking assembly 32 and a stacking assembly 34. The baling frame 31 is arranged at one end of the conveying frame 231 along the length direction of the workpiece 5. The stacking assembly 32 is arranged on the baling frame 31. The stacking assembly 32 is used to stack multiple workpieces 5 in sequence to form a workpiece group 53; the stacking assembly 34 is used to arrange multiple workpiece groups 53 in sequence to facilitate automatic packaging.

[0049] like Figure 2 and 4 As shown, the stacking assembly 32 includes a guide wheel 321 and a separator 33. The guide wheel 321 is rotatably connected to the baling frame 31, and the guide wheel 321 has a built-in magnetic block 322. The conveyor belt 232 transports the workpiece 5 along the length direction of the workpiece 5, so that the guide wheel 321 contacts the workpiece 5, and the magnetic block 322 and the workpiece 5 are attracted to each other. The separator 33 includes a separation cylinder 331 and a push block 332. The separation cylinder 331 is fixedly connected to the baling frame 31, and the push block 332 is fixedly connected to the end of the piston rod of the separation cylinder 331. The separation cylinder 331 drives the push block 332 to move up and down relative to the baling frame 31. The end of the baling frame 31 away from the conveyor frame 231 is fixedly connected to the limit plate 311. A pressure sensor is provided in the limit plate 311. The pressure sensor is electrically connected to the separation cylinder 331, and the pressure sensor is used to transmit a signal to the separation cylinder 331.

[0050] The workpiece 5 moves along the conveyor belt 232. When one end of the workpiece 5 abuts the stop plate 311, the workpiece 5 is in place. The pressure sensor on the stop plate 311 detects pressure and sends a signal to the separation cylinder 331. The separation cylinder 331 activates upon receiving the signal, driving the push block 332 to extend and move. The push block 332 abuts the workpiece 5, separating it from the guide wheel 321. After separation, the workpiece 5 naturally falls under its own weight. This cycle repeats, achieving automated stacking.

[0051] like Figure 2 As shown, the stacking assembly 34 includes a stacking frame 341, a stacking drive source, a stacking belt 344, a stacking rod 346 and a connecting shaft 347. The stacking frame 341 is arranged in the baling machine frame 31. The stacking frame 341 is rotatably connected to two stacking shafts 343. The stacking drive source is a stacking motor, which is fixedly connected to the stacking frame 341. The output shaft of the stacking motor is fixedly connected to one of the stacking shafts 343. The stacking belt 344 is wound around the two stacking shafts 343.

[0052] like Figure 2As shown, the stacking belt 344 is fixedly connected to a plurality of stacking balls 345, and the plurality of stacking balls 345 are evenly spaced along the length of the stacking belt 344. Stacking rods 346 are fixedly connected to the side of the stacking balls 345 facing away from the stacking belt 344, and the stacking balls 345 and the stacking rods 346 are both made of rubber. A storage space 348 is formed between each two adjacent stacking rods 346, and the storage space 348 is used to store the workpiece 5. The stacking belt 344 is provided with multiple stacking shafts 343 along the length of the workpiece 5, that is, multiple stacking shafts 343 are provided, and the multiple stacking shafts 343 are fixedly connected to each other via a connecting shaft 347.

[0053] like Figure 2 As shown, according to the PLC preset program, the separation cylinder 331 activates upon receiving a signal, driving the push block 332 to abut the workpiece 5, separating the workpiece 5 from the guide wheel 321. The separated workpiece 5 then naturally falls under its own weight into the storage space 348 located below the guide wheel 321. Multiple workpieces 5 are stacked sequentially under the restraining action of two adjacent stacking rods 346. When the number of workpieces 5 stacked in the current storage space 348 reaches a preset value, the stacking motor operates, driving the stacking shaft 343 to rotate, which in turn moves the stacking belt 344, thereby causing the stacked workpiece group 53 to move synchronously to make way for the next group.

[0054] like Figure 2 and 4 As shown, in order to further improve the quality of the workpiece 5 after processing and forming, a grinding assembly 4 is also included. The grinding assembly 4 includes a grinding frame 41, a grinding shaft 42 and a grinding wheel 43. The grinding frame 41 is arranged between the conveyor frame 231 and the packaging machine frame 31. A mounting groove 411 is provided on the grinding frame 41, and the mounting groove 411 is U-shaped. The grinding shaft 42 is rotatably connected to the grinding frame 41, and the two ends of the grinding shaft 42 are correspondingly inserted into the mounting groove 411. The grinding wheel 43 is rotatably connected to the grinding shaft 42. The axis of the grinding shaft 42 is parallel to the axis of the guide wheel 321. The wheel surface of the grinding wheel 43 is against the workpiece 5, and the surface of the workpiece 5 is further ground and polished during the movement of the workpiece 5.

[0055] The implementation principle of the automatic stacking and packaging device for angle steel in the embodiment of the present application is as follows:

[0056] After a series of processing, the angle steel is dried in the drying chamber 9 and moved to the placement platform 1. The transmission assembly 21 sequentially moves the multiple workpieces 5 out of the drying chamber 9 along its width direction. Then, the workpieces 5 pass through the flip rod 223, flip the angle, and continue to move with the transmission belt. They are sequentially moved to the conveyor belt 232. During the conveyor belt 232, the workpieces 5 are polished again by the grinding wheel 43. The workpieces 5 then move to contact the guide wheel 321. Under the adsorption effect of the magnetic block 322, the workpieces 5 and the guide wheel 321 always maintain contact. When the workpieces 5 move to abut the limit plate 311, the separation cylinder 331 operates to drive the push block 332 to move. The push block 332 pushes the workpiece 5 to separate from the guide wheel 321. Then, under the action of its own weight, the workpieces 5 enter the storage space 348.

[0057] According to the PLC preset counting program, the quantity in each workpiece group 53 is consistent. After the current workpiece 5 is stacked to form a workpiece group 53, the stacking motor runs to drive the stacking belt 344 to move, and the stacking belt 344 carries the workpiece group 53 to move, making way for the stacking of the next group of workpiece groups 53; the stacking assembly 32 continues to run to form the next workpiece group 53, saving the process of manually moving the stacked workpieces 5 and effectively improving the level of automated processing for stacking and packaging the workpieces 5.

[0058] The embodiment of the present application also discloses a production line using the angle steel automatic flipping, stacking and packaging equipment, such as Figure 1 As shown, the following steps are included:

[0059] Grinding: First, the bent workpiece 5 is preliminarily ground to remove surface burrs to facilitate subsequent surface galvanizing treatment;

[0060] Galvanizing: The workpiece 5 is moved to the galvanizing equipment 6, and the surface of the workpiece 5 after preliminary grinding is galvanized. The workpiece 5 can be placed in a zinc liquid pool to achieve surface galvanizing of the workpiece 5;

[0061] Cooling: After the galvanizing is completed, the workpiece 5 is transferred to a cooling pool 7 filled with coolant for cooling, so that the zinc liquid attached to the surface of the workpiece 5 solidifies and improves the bonding strength between the galvanized layer and the workpiece 5 itself;

[0062] Passivation: The galvanized and cooled workpiece 5 is transferred to the passivation equipment 8 for passivation. Acid solution can be used for passivation. Through chemical passivation, active ions on the surface of the workpiece 5 are removed, effectively reducing the possibility of rusting of the workpiece 5 during subsequent use;

[0063] Drying: The passivated workpiece 5 is transferred to the drying chamber 9 for drying. The drying chamber 9 is surrounded by connecting pipes. A heat medium, such as hot water, is introduced into the connecting pipes to maintain a high temperature in the entire drying chamber 9, which is conducive to achieving rapid drying of the workpiece 5.

[0064] Stacking: The dried workpieces 5 are moved out of the drying chamber 9 and onto the placement platform 1. The dried workpieces 5 are then automatically stacked and packaged using the automatic stacking and packaging equipment. This rational integration of multiple angle steel processing steps into one production line effectively reduces manual labor and improves angle steel processing efficiency.

[0065] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
