Description

Technical Field

[0001] The present application relates to the technical field of waste removal, and in particular to an automatic waste removal device and removal method based on real-time surface detection. Background Art

[0002] In the field of metal coil processing, after the metal coil is released by the unwinding mechanism, its free end needs to be pulled to the cutting equipment to be cut into metal sheets according to specified specifications. However, in actual production, due to factors such as the production process, material, transportation and storage environment, the coils often have local defects such as surface pitting, rust, and incompleteness. In traditional processing, in order to remove these defects to ensure the quality of subsequent products, workers will use the naked eye to judge the type and location of surface defects. Due to the limitations of the naked eye, this judgment method does not conform to the mechanism of real-time defect detection. It is impossible to accurately locate the defective area during cutting, resulting in defective coils being directly processed into finished products, resulting in a large number of defective products that need to be scrapped. This not only increases production costs but also reduces the overall quality of the product. Summary of the Invention

[0005] By adopting the above technical solution, the unwinding mechanism is first used to unwind the coil and the guiding mechanism is used to guide the coil flow. Then, the detection mechanism is used to detect surface defects of the coil. When the coil with defects reaches the cutting table, the control module operates the cutting drive based on the detection signal of the detection mechanism, thereby driving the cutter downward. At this time, the pressing block will press the coil, and then the cutter will enter the cutting groove to cut the coil. After the defective coil is cut, it is removed by the waste collection mechanism. This application can accurately cut off the defective coil.

[0006] Preferably, the detection mechanism includes at least two detection members connected to the frame, wherein the two detection members are a first detection member and a second detection member, and the first detection member and the second detection member are configured to be located on both sides of the coil, respectively.

The control module can control the operation of any waste removal component in response to the detection signal of the detection component.

[0013] By adopting the above technical solution, after the detection component determines the type of defect, the subsequently cut sheet material with defects reaches the side of a waste removal component, which starts to remove the waste material into the waste collection box. This application can collect different types of waste.

[0014] Preferably, the waste removal assembly includes an opening and closing plate, a rotating shaft is rotatably connected on the separation table, the opening and closing plate is connected to the rotating shaft, a blanking port is opened on the separation table, the opening and closing plate is used to open and close the blanking port, the opening and closing plate and the rotating shaft are also jointly connected with a torsion spring, and the waste collection box is arranged below the blanking port; a mounting shaft is rotatably connected below the opening and closing plate on the separation table, the mounting shaft is connected to a rotary drive component, a cam is provided on the mounting shaft, the torsion spring presses the opening and closing plate against the cam, and the rotary drive component is used to drive the mounting shaft to rotate, thereby driving the cam to rotate to drive the opening and closing plate to swing and then open and close the blanking port.

[0015] By adopting the above technical solution, when the waste reaches the opening and closing plate, the driving rotary drive component drives the mounting shaft to rotate, thereby driving the cam to rotate. At this time, under the action of the torsion spring, the opening and closing plate rotates to open the blanking port. At this time, the waste that continues to be transported will fall into the waste collection box. After the subsequent waste is removed, the driving rotary drive component is driven to reset the opening and closing plate.

[0016] Preferably, a frame is installed on the upper end of the opening and closing plate, and the frame is rotatably connected to a pressure wheel 1. A groove is opened on the upper end of the opening and closing plate, and the groove is rotatably connected to a pressure wheel 2.

After the coil with defects flows to the cutting table, the control module controls the cutting drive to drive the cutter to move and cut the coil with defects, and the waste collection mechanism removes the coil with defects.

[0021] By adopting the above technical solution, it is possible to easily remove the coil parts with defects at different positions.

[0022] Preferably, in step S2, for areas where the number of defects is densely distributed, the two defects that are farthest apart along the direction of coil movement are taken as two defect boundary positions, and a certain distance is reserved outward from each defect boundary position as a cutting position.

[0023] By adopting the above technical solution, the defective coil part can be efficiently cut off, and a certain position is reserved to ensure the reliability of waste material cutting and the subsequent flow stability of waste material.

[0024] In summary, the present invention includes at least one of the following beneficial technical effects: 1. First, the unwinding mechanism unwinds the coil, and the guiding mechanism directs its flow. The detection mechanism then inspects the coil for surface defects. When a defective coil reaches the cutting table, the control module activates the cutting drive based on the detection signal from the detection mechanism, driving the cutter downward. The pressure block then compresses the coil, and the cutter enters the cutting slot to cut the coil. After the defective coil is cut, the waste collection mechanism removes it. 2. After the detector determines the type of defect, the subsequently cut defective sheet material reaches one side of a waste removal component, which is activated to remove the waste material into a waste collection box. This application can collect different types of waste. Specifically, when the waste material reaches the opening and closing plate, the drive member drives the mounting shaft to rotate, thereby driving the cam to rotate. At this time, the opening and closing plate rotates under the action of the torsion spring to open the dropout port. At this time, the waste material that continues to be transported will fall into the waste collection box. After the waste material is subsequently removed, the drive member is driven to reset the opening and closing plate.

[0025] 3. The pressure wheels 1 and 2 can be used to guide the coil to flow on the opening and closing plate and can also limit the coil. The opening and closing plate quickly opens the blanking port to ensure that the waste can fall into the waste collection box in time, and the opening and closing plate slowly closes to prevent the defective coil that may have reached the upper end of the opening and closing plate from rapid deformation and causing structural damage.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

Specifically, the frame 1 includes a cutting table 11 and a separation table 12 connected to the cutting table 11. The separation table 12 is located on the left side of the cutting table 11. The cutting mechanism 5 is installed on one side of the cutting table 11, and the waste collection mechanism 6 is provided on the separation table 12. The automatic waste cutting device based on real-time surface detection also includes a control module installed on the frame 1. The detection mechanism 4 and the cutting mechanism 5 are both connected to the control module. The control module controls the operation of the cutting mechanism 5 in response to the detection signal of the detection mechanism 4.

[0032] First, the unwinding mechanism 2 unwinds the coil, which is then guided by the guiding mechanism 3. Then, the detection mechanism 4 detects the location of defects on the coil surface and sends a signal to the control module. When the defective coil flows onto the cutting table 11, the control module controls the cutting mechanism 5 to cut the defective coil. The waste collection mechanism 6 then removes the defective coil when the waste flows to the separation table 12. Of course, it should be noted that the flow of the coil needs to be suspended while the cutting mechanism 5 is cutting the coil.

[0033] Reference Figure 1 The unwinding mechanism 2 includes an unwinding roller 21 rotatably connected to the frame 1. The unwinding roller 21 is connected to a motor. The specific structure of the unwinding roller 21 is prior art and will not be described here.

[0034] Reference Figure 1 and Figure 2The guiding mechanism 3 includes a plurality of guiding roller groups 31 and a plurality of pressing guiding components 32 installed on the frame 1. The plurality of pressing guiding components 32 mainly guide the movement of the coiled material arriving at the separation table 12; the guiding roller group 31 includes a first guiding roller 311 and a second guiding roller 312 connected to the frame 1. The first guiding roller 311 and the second guiding roller 312 are distributed vertically. A feeding area 313 for the coiled material to pass through is formed between the first guiding roller 311 and the second guiding roller 312. The first guiding roller 311 is connected to a feeding member, which is a motor. In this embodiment, a plurality of first guiding rollers 311 and second guiding rollers 312 are provided along the direction of the coiled material flow channel.

[0035] Reference Figure 1 and Figure 3 The pressing guide assembly 32 includes a connecting column 321 connected to the frame 1, and a sliding column 322 is slidably connected to the connecting column 321. The sliding column 322 and the connecting column 321 are commonly connected to an elastic member 323, and the elastic member 323 is preferably a spring. A pressing wheel 324 is rotatably connected to the sliding column 322, and the pressing wheel 324 is connected to a belt rotating member, which is preferably a motor.

[0036] Reference Figure 2 The detection mechanism 4 includes at least two detection members connected to the frame 1. In this embodiment, there are two detection members, and the detection members are preferably CCD cameras. The detection members are connected to the control module, wherein the two detection members are a first detection member 41 and a second detection member 42. The first detection member 41 and the second detection member 42 are configured to be located on both sides of the coil, respectively. The first detection member 41 is used to detect the upper end surface of the coil, and the second detection member 42 is used to detect the lower end surface of the coil.

[0037] Reference Figure 4 Since there is a certain distance between the cutting table 11 and the separating table 12, in order to ensure that the waste coil can be moved from the cutting table 11 to the separating table 12, a receiving groove 13 is opened at the connection between the cutting table 11 and the separating table 12. The receiving groove 13 is rotatably connected to multiple rotating rods 33, and the multiple rotating rods 33 are commonly connected to a sprocket transmission assembly 34. The sprocket transmission assembly 34 is used to drive the multiple rotating rods 33 to rotate synchronously. The specific structure of the sprocket transmission assembly 34 is existing technology and will not be repeated here.

[0038] Reference Figure 5 and Figure 6The cutting mechanism 5 includes a fixed frame 51 connected to the cutting table 11, and the fixed frame 51 is equipped with a cutting drive 52, which is preferably a cylinder. The cutting drive 52 is connected to a cutter 53, and a cutting groove 111 is opened at the upper end of the cutting table 11 for the cutter 53 to cut; the cutter 53 is slidably connected to a pressing block 54, and the pressing block 54 and the fixed frame 51 are also commonly connected to a pressure spring 55. The cutting drive 52 is used to drive the pressing block 54 to press the coil so that the cutter 53 moves into the cutting groove 111 to cut the coil.

[0039] After the detection part detects the location of the defect on the roll, it sends a signal to the control module. After the defective part of the roll reaches the cutting table 11, the control module controls the cutting drive part 52 to drive the cutter 53 to move and cut the roll. Usually, the cutting action must be performed at least twice to cut off the part of the roll where the defect is located.

[0040] Reference Figure 5 and Figure 7 The waste collection mechanism 6 includes a plurality of waste removal components 61 installed on the separation table 12 for removing waste, and each waste removal component 61 is connected to the control module; the separation table 12 is also provided with a waste collection box 62 with an upward opening below each waste removal component 61. In this embodiment, there are three waste collection boxes 62. The frame 1 is also provided with a detection member 63 for detecting the type of defects of the coiled material on the separation table 12. The detection member 63 is also preferably a CCD camera. The detection member 63 is also connected to the control module. The control module can control the operation of any waste removal component 61 in response to the detection signal of the detection member 63. Figure 1 In addition, in order to facilitate the removal of the waste collection box 62, a plurality of opening and closing doors 64 are installed on the separation table 12.

[0041] When the cut scrap coils arrive at the separation table 12, the detector 63 detects the type of defects, such as potholes, rust, and damage. Based on the defect type, the scrap coils are directed to different scrap collection boxes 62 and then removed by the scrap collection mechanism 6. This application can classify and collect different types of scrap coils, which facilitates subsequent processing, restoration, or recycling of the scrap coils.

[0042] Reference Figure 7 , take one of the waste removal components 61 as an example: the waste removal component 61 includes an opening and closing plate 611, the opening and closing plate 611 is arranged horizontally, the separation table 12 is rotatably connected to a rotating shaft 612, the opening and closing plate 611 is connected to the rotating shaft 612, the separation table 12 is provided with a blanking port 121, the opening and closing plate 611 is used to open and close the blanking port 121, the opening and closing plate 611 and the rotating shaft 612 are also connected to a torsion spring, combined Figure 5The waste collection box 62 is arranged below the blanking port 121; the separation table 12 is located below the opening and closing plate 611 and is rotatably connected to a mounting shaft 613, the mounting shaft 613 is connected to a rotary drive component, and the rotary drive component is preferably a motor, and the rotary drive component is connected to the control module. A cam 614 is provided on the mounting shaft 613, and a torsion spring presses the opening and closing plate 611 against the cam 614. The rotary drive component is used to drive the mounting shaft 613 to rotate, thereby driving the cam 614 to rotate to drive the opening and closing plate 611 to swing and then open and close the blanking port 121.

[0043] Reference Figure 7 The cam 614 includes an involute guide surface 6141 on the outer wall; the cam 614 has a first position and a second position. When the cam 614 moves from the first position to the second position, the opening and closing plate 611 can quickly open the blanking port 121. When the cam 614 moves from the second position to the first position, the opening and closing plate 611 can slowly close the blanking port 121.

[0044] Reference Figure 7 A frame 7 is installed on the upper end of the opening and closing plate 611, and the frame 7 is rotatably connected to a pressure wheel 71. A groove 6111 is opened on the upper end of the opening and closing plate 611, and the groove 6111 is rotatably connected to a pressure wheel 2 72. The pressure wheel 1 71 and the pressure wheel 2 72 are arranged vertically, and a material passing area 73 for the coil to pass through is formed between the pressure wheel 1 71 and the pressure wheel 2 72. The pressure wheel 1 71 is connected to a rotating drive member, and the rotating drive member is connected to the control module. The rotating drive member is preferably a motor.

[0045] When the waste reaches one of the opening and closing plates 611, the driving member drives the mounting shaft 613 to rotate, thereby driving the cam 614 to rotate, and the cam 614 moves from the first position to the second position. At this time, the opening and closing plate 611 will rotate counterclockwise under the action of the torsion spring to open the blanking port 121. At this time, the waste that is continued to be transported by the pressure wheel 1 71 and the pressure wheel 2 72 will continue to move along the upper end surface of the opening and closing plate 611 and fall into the waste collection box 62. After the waste is subsequently removed, the driving member is driven to make the cam 614 move from the second position to the first position, thereby resetting the opening and closing plate 611.

[0046] Of course, in order to quickly make the waste coils fall into the waste collection box 62, after the waste coils reach the opening and closing plate 611, the control module can control the rotating drive member to drive the pressure wheel 71 to accelerate the movement to accelerate the flow of the waste coils.

[0047] In addition, the opening and closing plate 611 quickly opens the drop port 121 to ensure that the waste can fall into the waste collection box 62 in time, and the slow closing of the opening and closing plate 611 can prevent the defect-free coil that may have reached the upper end of the opening and closing plate 611 from being quickly deformed and causing damage to the coil structure.

[0048] The implementation principle of the waste automatic cutting device based on real-time surface detection in the embodiment of the present application is as follows: First, the unwinding roller 21 unwinds the coil, and the guide rollers 31 and the pressing guide assemblies 32 guide the coil flow, so that the coil flows from right to left. During the flow of the web, the first inspection member 41 and the second inspection member 42 first inspect both sides of the web for defects. After a defect is detected, a signal is sent to the control module. When the defective web portion reaches the cutting table 11, the control module controls the cutting drive member 52 to drive the cutter 53 to move downward to cut the web. The cutting action is performed at least twice to cut off the defective web portion, i.e., the waste web. The subsequent waste coils arrive at the separation table 12 under the guidance of multiple rotating rods 33 and pressing guide assemblies 32. The detection component 63 judges the type of defects on the waste coils and sends a signal to the control module. Based on the defect type, after the waste coils flow to the top of the corresponding waste collection box 62, the driving drive component drives the mounting shaft 613 to rotate, thereby driving the cam 614 to rotate, and the cam 614 moves from the first position to the second position. At this time, the opening and closing plate 611 will rotate counterclockwise under the action of the torsion spring to open the blanking port 121. At this time, the waste that is continued to be transported by the pressure wheel 1 71 and the pressure wheel 2 72 will continue to move along the upper end surface of the opening and closing plate 611 and fall into the waste collection box 62. After the subsequent waste is removed, the driving drive component is driven to make the cam 614 move from the second position to the first position, thereby resetting the opening and closing plate 611.

[0049] The present application also discloses a cutting method for a waste material automatic cutting device based on real-time surface detection, comprising the following steps: S1: The coil is unwound by the unwinding mechanism 2 and guided by the guiding mechanism 3; S2: The detection mechanism 4 detects the defect position on the surface of the coil and sends a signal to the control module. After the defective coil flows onto the cutting table 11, the control module controls the cutting drive 52 to drive the cutter 53 to move and cut the defective coil, and the waste collection mechanism 6 removes the defective coil.

[0050] Reference Figure 8 For areas with densely distributed defects, the two defects furthest apart along the web's travel direction are designated as the two defect boundary locations a. A certain distance is reserved outward from each defect boundary location a as the cutting location b. In this embodiment, this distance is 750 mm, but other values ​​are possible in other embodiments. This reserved distance ensures reliable waste removal and subsequent waste flow stability.

[0051] Specifically, in this embodiment, a large-area cutting method is used to partially cut off the defective coil. This cutting method is more efficient but more consumable. In other embodiments, a small-area coil with defects can also be cut off, that is, the distance reserved outward from the defect boundary position a is smaller. This cutting method is more material-saving, but the cutting efficiency is not high, and the flow of the coil is often paused.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
