Description

Technical Field

[0001] This invention relates to a horizontal packing machine, and more particularly to a corner wrapping mechanism and corner wrapping method for a horizontal packing machine. Background Technology

[0002] High-quality hard wire rods produced by high-speed wire rod production are automatically bundled using horizontal baling machines during packaging. Currently, four binding steel wires (strips) are used to directly tighten the rods. Due to the high binding tension of the binding steel wires (strips), the following problems occur when they come into contact with the left and right ends of the rods: the bending points of the binding steel wires (strips) are most prone to scratches on the rods, causing surface quenching and the formation of martensite. Martensite has extremely poor plasticity, and some of these scratches are not visible to the naked eye, while others even form pits. At the same time, during transportation, the ends of the rods are also prone to friction with the binding steel wires (strips) and are scratched. Martensite and pits directly reduce the quality of the high-speed wire rods, leading to wire breakage during subsequent drawing processes, affecting the continuity of downstream customers' production, reducing the product yield, causing significant product waste, increasing production costs, and raising safety hazards in the production process.

[0003] To avoid the above situation, some manufacturers now use sleeve-type hoppers installed in the front and rear directions of the pressure plate column. The continuous gaskets inside the sleeve-type hoppers are transported to positions close to the left and right pressure plates and corresponding to the four binding lines by a servo motor-driven sprocket. During bundling, the gaskets cover the wire rods for protection. The disadvantages of this structure are: 1. The gaskets are a continuous roll structure, and the joints between each gasket require special treatment (such as serrations) to separate from the following gaskets during pressing. Therefore, the gasket manufacturing process is complex, the price is high, and the procurement cycle is long. Furthermore, new gaskets can only be placed in the hopper after all the existing gaskets have been used, significantly reducing production efficiency. 2. Because the gaskets are only located in waiting positions… There is no dedicated device for its placement, resulting in poor stability. Therefore, during the tightening of the binding line, positional deviations are prone to occur, reducing the reliability of the wrapping angle. At the same time, the tensioning force impacts other pads and servo motors, affecting the overall performance of the feeding device. In addition, during tightening, there is a risk that the pads may not separate from the whole unit, thus affecting the success rate of the wrapping angle. Third, because the sleeve-type hopper is far from the front and rear of the pressure plate column, the equipment occupies a large space, which increases the risk of safety accidents. Fourth, since the pads must be close to the pressure plate to improve its stability, some of the wear-resistant plate is removed to avoid friction between the motor and chain conveying channels and the wear-resistant plate on the surface of the pressure plate, increasing the probability of damage during the coil compression process. Summary of the Invention

[0004] The problem this invention aims to solve is to provide a corner-wrapping device for a horizontal baling machine. This device uses a corner-wrapping robot to directly place pads into the corner-wrapping unit, simultaneously compressing the pads at eight points where the four binding wires (strips) contact the left and right ends of the wire rod during the baling process. This isolates the binding wires (strips) from direct contact with the ends of the wire rod, preventing damage to the ends of the wire rod in the bending areas of the binding wires (strips). Furthermore, the pads used in corner wrapping are simple to manufacture, inexpensive, and reduce the supply cycle by approximately 30%, significantly improving production efficiency. In addition, the pads are reliably placed on the corner-wrapping unit before corner wrapping, exhibiting excellent stability. Therefore, during the tightening of the binding wires, the corner wrapping is reliable and the position is fixed, improving the success rate and reliability of corner wrapping. This invention also provides a corner-wrapping method for a horizontal baling machine.

[0005] The present invention relates to a corner wrapping device for a horizontal baling machine, comprising four sets of feeding mechanisms 1, four sets of corner wrapping units I, and four sets of corner wrapping units II. Each of the front and rear outer sides of the column of pressure plate I is equipped with a feeding mechanism, and each of the four wire feeding devices is equipped with a corner wrapping unit I. Each feeding mechanism of pressure plate I feeds material to two adjacent sets of corner wrapping units I. Similarly, each of the front and rear outer sides of the column of pressure plate II is equipped with a feeding mechanism, and each of the four anti-scratch devices is equipped with a corner wrapping unit II. Each feeding mechanism of pressure plate II feeds material to two adjacent sets of corner wrapping units II. The corner wrapping units are located at the left and right ends of the wire rod where they contact the binding steel wire (strip).

[0006] Furthermore, each feeding mechanism includes a robot, a double clamp, an L-shaped mounting base, a mounting plate, a hopper device, and a gasket; the fixed end of the robot is connected to one side of the L-shaped mounting base, and the other side of the L-shaped mounting base is connected to the column through the mounting plate; the movable end of the robot is connected to the double clamp, the hopper device is located below the robot and is fixedly connected to the column, and the gasket is located in the hopper device.

[0007] Furthermore, the dual clamp includes a Y-shaped clamp body and two suction components. Each suction component is provided on one of the two symmetrical inclined sides of the Y-shaped clamp body. Each suction component includes a suction cup and two suction units, one in front and one in back. Each suction unit includes a spring, a sliding rod, and a flanged copper sleeve. The suction cup is located below the inclined side of the Y-shaped clamp body. The flanged copper sleeve is inserted into the hole in the inclined side. The middle section of the sliding rod is engaged with the inner hole of the flanged copper sleeve, and the lower section is engaged with the inner hole of the suction cup. The spring is sleeved on the outer circle of the sliding rod located between the flanged copper sleeve and the suction cup. The vertical rod of the Y-shaped clamp body is connected to the movable end of the robot.

[0008] Furthermore, each suction assembly also includes a bracket and a proximity switch. The bracket is fixed on the upper side of the inclined side of the Y-shaped clamp body, and the proximity switch is fixed on the bracket and located outside the sliding rod.

[0009] Furthermore, the silo device has an open structure, consisting of a base plate and four angle steels vertically installed at the four corners.

[0010] Furthermore, each set of corner protection unit I includes two suction cups I, and each wire feeding device includes two front and rear arc pressure plates. Each arc pressure plate has a suction cup I at its right end, and the width dimension formed by two adjacent suction cups I is not less than the width dimension of the pad.

[0011] Furthermore, the end of suction cup I facing the packing head has a bend towards the gasket.

[0012] Furthermore, each set of corner protection unit II includes two suction cups II, and each anti-scratch device includes a support and a cover plate. Each of the support plate and the cover plate has a suction cup II at its left end, and the width dimension formed by two adjacent suction cups II is not less than the width dimension of the pad.

[0013] The corner wrapping method of the horizontal baling machine of the present invention comprises the following steps: ① The robot picks up two pads from the hopper device through the double clamps and sends the two pads to the two adjacent corner wrapping units at one time, with four robots working simultaneously; ② The baling machine performs the baling operation, so that a pad is wrapped at each of the eight positions where the four binding steel wires (strips) and the left and right ends of the wire rods come into contact.

[0014] The specific steps of the robot's operation in step ① are as follows: First, one suction component is sent downward into the hopper device to pick up the pad, then the suction component is sent upward to make the pad leave the hopper device. Next, the movable end connected to the double clamp is rotated 180 degrees. Then, another suction component is sent downward into the hopper device to pick up the pad and the suction component is sent upward to make the pad leave the hopper device. Finally, the robot extends into the packing machine from the front (or back) and sends the two pads into the upper and lower corner units closest to its position.

[0015] The advantages of the corner-wrapping device of the horizontal baling machine of this invention are as follows: 1. Since the corner-wrapping robot directly puts the pads into the corner-wrapping unit, ordinary-shaped pads can be placed horizontally from bottom to top in the hopper device, eliminating the need for specially made continuous pads. Therefore, the pad manufacturing process is simple, the price is low, and the supply cycle is reduced by about 30%. At the same time, the corner pads are stored horizontally in the material preparation device, making it convenient and quick to add pads and ensuring that there are always pads in the hopper device, greatly improving production efficiency. 2. The pads are reliably placed on the corner-wrapping unit before corner wrapping, with excellent stability. Therefore, during the tightening of the binding line, the corner wrapping is reliable and the position is fixed, improving the success rate and reliability of corner wrapping. 3. Since the hopper device is directly fixed to the front and rear sides of the pressure plate column, the distance between the hopper and the edge of the pressure plate is optimized from 900mm of the sleeve type to 430mm, reducing the space occupied by the equipment and improving equipment and personnel safety. 4. The robot's flexible feeding means that the size of the wear-resistant plate on the pressure plate does not need to be changed, protecting the coil from damage during compression.

[0016] This invention's corner-wrapping device ensures that during the packaging process of high-strength wire rod, the pads at eight points where the four binding steel wires (strips) contact the left and right ends of the wire rod are simultaneously pressed together. This isolates the binding steel wires (strips) from direct contact with the ends of the wire rod, preventing damage to the ends of the wire rod in the bending areas of the binding steel wires (strips). Simultaneously, it also prevents abrasions on the wire rod surface caused by contact between the binding steel wires (strips) and the wire rod during transportation. Therefore, it guarantees the quality of the high-strength wire rod, prevents wire breakage during subsequent wire drawing, ensures the continuity of production for downstream customers, improves product yield, saves product, reduces production costs, and minimizes safety hazards during production.

[0034] Example 1

[0035] from Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 , Figure 17 It is understood that the corner wrapping device of the horizontal baling machine of the present invention includes four sets of feeding mechanisms 1, four sets of corner wrapping units I 2, and four sets of corner wrapping units II 3; a set of feeding mechanisms 1 is provided on the front and rear outer sides of the column 6 of the pressure plate I, and a set of corner wrapping units I 2 is provided on each of the four wire feeding devices 4. Each set of feeding mechanisms 1 of the pressure plate I feeds material to two adjacent sets of corner wrapping units I 2; a set of feeding mechanisms 1 is provided on the front and rear outer sides of the column 7 of the pressure plate II, and a set of corner wrapping units II 3 is provided on each of the four anti-scratch devices 5. Each set of feeding mechanisms 1 of the pressure plate II feeds material to two adjacent sets of corner wrapping units II 3.

[0036] Corner wrapping units I2 and II3 are located at the left and right ends of the wire rod and the contact points with the binding steel wires (strips). Before the horizontal baler packages the high-strength wire coil, each feeding mechanism is responsible for placing pads on the two nearest adjacent corner wrapping units. This ensures that during the packaging and tightening process, the pads at the eight corner positions where the four binding steel wires (strips) contact the left and right ends of the wire rod are simultaneously pressed and wrapped on the wire rod. This isolates the binding steel wires (strips) from direct contact with the ends of the wire rod, preventing damage to the bending areas of the ends of the wire rod, i.e., the binding steel wires (strips). It also prevents scratches on the surface of the wire rod caused by contact between the binding steel wires (strips) and the wire rod during transportation.

[0037] Example 2

[0038] from Figure 1 , Figure 2 It can be seen that the corner wrapping device of the horizontal baling machine of the present invention includes: each feeding mechanism 1 includes a robot 11, a double clamp 12, an L-shaped mounting base 13, a mounting plate 14, a hopper device 15, and a gasket 16; the fixed end of the robot 11 is connected to one side of the L-shaped mounting base 13, and the other side of the L-shaped mounting base 13 is connected to the column through the mounting plate 14; the movable end of the robot 11 is connected to the double clamp 12, the hopper device 15 is located below the robot 11 and is fixedly connected to the column, and the gasket 16 is located in the hopper device 15.

[0039] The gasket 16 is placed into the hopper device 15, and the robot 11 picks up the gasket 16 through the double gripper 12 and places it into the corner wrapping unit to realize the subsequent corner wrapping work.

[0040] Example 3

[0041] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It is understood that the corner-wrapping device of the horizontal packing machine of the present invention includes a double clamp 12 comprising a Y-shaped clamp body 121 and two suction components. Each suction component is provided on one of the two symmetrical inclined sides of the Y-shaped clamp body 121. Each suction component includes a suction cup 125 and two suction units, each suction unit including a spring 122, a sliding rod 123, and a flanged copper sleeve 124. The suction cup 125 is located below the inclined side of the Y-shaped clamp body 121. The flanged copper sleeve 124 is inserted into the hole of the inclined side. The middle section of the sliding rod 123 is engaged with the inner hole of the flanged copper sleeve 124, and the lower section is engaged with the inner hole of the suction cup 125. The spring 124 is sleeved on the outer circle of the sliding rod 123 located between the flanged copper sleeve 124 and the suction cup 125. The vertical rod of the Y-shaped clamp body 121 is connected to the movable end of the robot 11.

[0042] Robot 11 operates by moving the double gripper 12 into the hopper device 15. When the suction cup 125 contacts the pad, it moves the pad out of the hopper device 15 and then into the corner unit. To improve feeding efficiency, robot 11 uses the double gripper 12 to move up and down to pick up one pad from each suction component and then feeds two pads into the corner unit.

[0043] Example 4

[0044] from Figure 3 , Figure 4 , Figure 5 It is understood that the corner wrapping device of the horizontal baling machine of the present invention includes a bracket 126 and a proximity switch 127 in each suction component. The bracket 126 is fixed on the upper side of the inclined side of the Y-shaped clamp body 121, and the proximity switch 127 is fixed on the bracket 126 and located outside the sliding rod 123.

[0045] After the suction cup 125 contacts the pad, the robot 11 moves downward. Since the suction cup 125 has no room to descend, the sliding rod 123 drives the suction cup 125 and the pad to move upward under the action of the spring 122. When the sliding rod 123 comes to the proximity switch 127, it means that the pad 16 has been sucked up. At this time, the robot 11 moves upward and takes the pad 16 away from the hopper device 15.

[0046] Example 5

[0047] from Figure 1 It can be seen that the corner wrapping device of the horizontal baler of the present invention: the hopper device 15 is an open structure, consisting of a base plate and four angle steels vertically arranged at the four corners.

[0048] The open-structure hopper device 15 ensures that when a pad is picked up on one of the suction components of the dual clamps 12, the other suction component will not interfere with the hopper device 15. The hopper device 15 only needs to ensure that the pad does not fall out.

[0049] Example 6

[0050] from Figure 1 It can be seen that the corner wrapping device of the horizontal baler of the present invention: each feeding mechanism 1 also includes a support base 17, one end of the support base 17 is connected to the column, and the other end supports the hopper device 15.

[0051] The support base 17 supports the hopper device 15 and prevents the hopper device 15 from sagging when it is filled with gaskets 16.

[0052] Example 7

[0053] from Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13, Figure 14 It can be seen that the corner wrapping device of the horizontal packing machine of the present invention includes: each corner wrapping unit I2 includes two suction cups I21, each wire feeding device 4 includes two front and rear arc pressure plates 41, and each arc pressure plate 41 has a suction cup I21 at the right end, and the width dimension formed by two adjacent suction cups I21 is not less than the width dimension of the pad 16.

[0054] After the robot 11 delivers the pad 16 to the suction cups I21 on the right end of the two arc-shaped pressure plates 41, it prepares for corner wrapping. While the binding wire (strip) tightens the coil, the pad 16 is wrapped around the left end of the coil, preventing the binding wire (strip) from directly contacting the coil at this point, thus protecting the coil. Since the wire feeding device is existing technology, this invention will not be described in detail here.

[0055] Example 8

[0056] from Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13 , Figure 14 It can be seen that the corner-wrapping device of the horizontal baling machine of the present invention has a curved angle facing the pad 16 at the end of the suction cup I21 facing the baling head 8.

[0057] When the pad 16 is placed on the suction cup I21, the part of it facing the packing head forms a certain degree of curvature, so that when the packing head is pressed down, it can reliably touch the pad 16 to achieve bending and pressing of the pad 16.

[0058] Example 9

[0059] from Figure 6 , Figure 7 , Figure 11 , Figure 12 , Figure 13 , Figure 14 It is known that the corner wrapping device of the horizontal baling machine of the present invention has a downward bend at the end of the flap of the baling head 8 facing the suction cup I21, and does not interfere with the bend of the suction cup I21.

[0060] During the downward pressing process, the packing head presses against the gasket through its bend. Since the gasket 21 already has a slight bend, it can make better contact with the gasket, thus bending the gasket 16 and pressing it onto the left end of the wire rod. Since the packing head is existing technology, this invention will not be described in detail here.

[0061] Example 10

[0062] from Figure 8 , Figure 9 , Figure 11 , Figure 15 , Figure 16, Figure 17 It can be seen that the corner wrapping device of the horizontal packing machine of the present invention includes two suction cups II31 in each corner wrapping unit II3, and each anti-scratch device 5 includes a support 51 and a cover plate 52. Each of the support plate 51 and the cover plate 52 is provided with a suction cup II31 at the left end. The width dimension formed by two adjacent suction cups II31 is not less than the width dimension of the pad 16.

[0063] After the robot 11 delivers the pad 16 to the suction cups II 31 at the left ends of both the support 51 and the cover plate 52, it prepares for corner wrapping. While the binding wire (strip) tightens the coil, the pad 16 is wrapped around the right end of the coil, preventing the binding wire (strip) from directly contacting the coil at this point, thus protecting the coil. Since the anti-scratch device is existing technology, it will not be described in detail here.

[0064] In this invention: the gasket 16 can be a plastic gasket, a felt gasket, or a metal gasket. Steel mills can select corner protection gaskets of different materials according to the steel type and the requirements of downstream customers. At the same time, the specific selection of suction cups 125, suction cup I 21, and suction cup II 31 depends on the material of the gasket 16.

[0065] Example 11

[0066] The corner wrapping method of the horizontal baling machine of the present invention comprises the following steps: ① The robot picks up two pads from the hopper device through the double clamps and sends the two pads to the two adjacent corner wrapping units at one time, with four robots working simultaneously; ② The baling machine performs the baling operation, so that a pad is wrapped at each of the eight positions where the four binding steel wires (strips) and the left and right ends of the wire rods come into contact.

[0067] Four of the robots are controlled by a controller, while the vacuum sponge suction cups are controlled by a vacuum generator. They are interconnected with the packaging machine on the PLC program to complete the function of protecting the end face of the coil.

[0068] In order to reduce the frequency of adding gaskets at the four workstations, each workstation should place no less than 1,600 metal gaskets at a time, which can be used to continuously bundle more than 800 bundles of wire rod; and no less than 400 plastic or felt gaskets, which can be used to continuously bundle more than 200 bundles of wire rod.

[0070] The corner wrapping method of the horizontal baling machine of the present invention: The specific steps of the robot's operation in step ① are as follows: First, a suction component is sent downward into the hopper device to pick up the pad, and then the suction component is sent upward to make the pad leave the hopper device. Next, the movable end connected to the double clamp is rotated 180 degrees. Then, another suction component is sent downward into the hopper device to pick up the pad and the suction component is sent upward to make the pad leave the hopper device. Finally, the robot extends into the baling machine from the front (or back) and sends the two pads into the upper and lower corner wrapping units closest to its position.

[0071] The advantages of the corner-wrapping device of the horizontal baling machine of this invention are as follows: 1. Since the corner-wrapping robot directly puts the pads into the corner-wrapping unit, ordinary-shaped pads can be placed horizontally from bottom to top in the hopper device, eliminating the need for specially made continuous pads.

At the same time, the corner pads are stored horizontally in the material preparation device, making it convenient and quick to add pads and ensuring that there are always pads in the hopper device, greatly improving production efficiency. 2. The pads are reliably placed on the corner-wrapping unit before corner wrapping, with excellent stability. Therefore, during the tightening of the binding line, the corner wrapping is reliable and the position is fixed, improving the success rate and reliability of corner wrapping. 3. Since the hopper device is directly fixed to the front and rear sides of the pressure plate column, the distance between the hopper and the edge of the pressure plate is optimized from 900mm of the sleeve type to 430mm, reducing the space occupied by the equipment and improving equipment and personnel safety. 4.
