DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0050] like Figure 1 As shown, an embodiment of the present invention provides an intelligent corrugated cardboard sorting device, the sorting device comprising:

[0051] Feeding and conveying part 100;

[0052] The detection unit 200 and the control unit 400 provided on the feeding and conveying unit 100 are used to detect the size and surface quality of the corrugated paper;

[0053] The sorting section 300 , under the control of the control section 400 , transfers the corrugated cardboards whose size and surface quality meet the preset parameters to the next process.

[0054] Specifically, when loading corrugated cardboard, the loading device of the carton production line places the corrugated cardboard on the loading conveying part 100, and the corrugated cardboard moves with the loading conveying part 100. In the process of the corrugated cardboard moving to the sorting part 300, the corrugated cardboard flows through the detection part 200, and the detection part 200 detects the size and surface quality of the corrugated cardboard. The control part 400 controls the operation of the sorting part 300 based on the detection result to control the flow direction of the corrugated cardboard. For example, when the size and surface quality of the corrugated cardboard meet the preset values, the sorting part 300 controls the corrugated cardboard to flow to the next process. When one of the size or surface quality of the corrugated cardboard does not meet the preset value, the sorting part 300 controls the corrugated cardboard to leave the production line.

[0055] The intelligent corrugated cardboard sorting device disclosed in the embodiment of the present invention is provided with a detection unit 200 in the loading stage, and the detection unit 200 detects the size and surface quality of the corrugated cardboard. When the size and surface quality of the corrugated cardboard meet the preset values, the control unit 400 controls the sorting unit 300 to flow to the next process, thereby preventing the size of the corrugated cardboard from being wrong or the surface quality from not meeting the requirements, thereby achieving the effect of improving the yield rate of the carton.

[0056] Specifically, in this embodiment, the loading conveyor part 100 is a conveying structure in the prior art, such as a belt conveying structure.

[0057] As a preferred implementation in this embodiment, Figure 2 As shown, the detection unit 200 includes a linear laser 220 and an image acquisition module 230. When the laser of the linear laser 220 is irradiated onto the corrugated paper, a linear light spot perpendicular to the flow direction of the feeding conveying unit 100 is generated. The light curtain of the laser of the linear laser 220 is inclined to the conveying surface of the feeding conveying unit 100. The image acquisition module 230 is used to obtain image information of the corrugated paperboard. The image acquisition module 230 sends the obtained image information to the control unit 400. The control unit 400 calculates the size and surface quality of the corrugated paperboard based on the image information sent by the image acquisition module 230.

[0058] Specifically, in this embodiment, the linear laser 220 and the image acquisition module 230 are fixedly connected to the bracket 210, the bracket 210 is fixedly connected to one side of the loading and conveying part 100, the image acquisition module 230 is located directly above the loading and conveying part 100, the central axis of the image acquisition module 230 is perpendicular to the conveying surface of the loading and conveying part 100, and the image acquisition module 230 is a COMS camera.

[0059] As a preferred implementation in this embodiment, Figures 3 to 5As shown, the sorting part 300 includes a sorting bracket 310, a sorting roller 320, a sorting roller 330, a roller lifting part 350 and a roller power motor 340. The sorting roller 320 and the sorting roller 330 are both provided with a plurality of roller wings 321 evenly spaced on each of the sorting rollers 320. The sorting roller 330 is located between adjacent sorting rollers 320. When the sorting roller 320 rotates, the sorting roller 330 is driven to rotate by the roller wings 321. The rotating surface of the roller wings 321 is aligned with the rotating surface of the sorting roller 330. The roller lifting part 350 is used to drive the sorting roller 330 to rise and fall, so as to control the contact or separation between the sorting roller 330 and the roller wings 321. The roller power motor 340 is used to drive the sorting roller 320 to rotate.

[0060] Specifically, in this embodiment, the sorting bracket 310 is a box-shaped structure arranged at both ends of the sorting roller 320, and the sorting bracket 310 is provided with supporting feet. The two ends of the sorting roller 320 are rotatably connected to the sorting bracket 310 through bearings. The roller wing plate 321 is a disc structure, and a plurality of the roller wing plates 321 are equidistantly fixed on the sorting bracket 310. The outer edge of the roller wing plate 321 is tangent to the edge of the sorting roller 330. When the wing plate 321 rotates, the roller wing plate 321 drives the sorting roller 330 to rotate. The sorting roller 330 is fixedly connected to the roller mounting plate 332 through the roller bracket 331. The roller bracket 331 is a U-shaped bracket. The roller bracket 331 and the sorting roller 330 are connected through a bearing. The roller bracket 331 is fixedly connected to the roller mounting plate 332 by bolts. The output end of the roller lifting part 350 is fixedly connected to the roller mounting plate by bolts. 332 is a side away from the sorting roller 330, and the roller lifting part 350 controls the lifting and lowering of the sorting roller 330 through the roller mounting plate 332. When the sorting roller 330 descends, the sorting roller 330 is disengaged from the roller wing 321, so that the roller wing 321 will not drive the sorting roller 330 to rotate. The roller power motor 340 is fixedly connected to the feeding conveying part 100, and the roller power motor 340 drives the sorting roller 320 to rotate through a gear structure. The sorting roller 320 is located in the end of the sorting bracket 310 and is fixed with a driven gear through a key shaft. A transition gear is arranged between adjacent driven gears. The driven gear and the transition gear are meshed, so that the rotation directions of the multiple sorting rollers 320 are the same. The output end of the roller power motor 340 is provided with a driving gear, and the driving gear is meshed with one of the driven gears, so that the roller power motor 340 can drive the driven gear to rotate.

[0061] Preferably, in this embodiment, each of the roller wing plates 321 contacts the sorting rollers 330 on both sides, and the sorting rollers 330 located in different columns are arranged at intervals, so that when the same roller wing plate 321 contacts the sorting rollers 330 in different columns, the roller wing plates 321 are respectively located in different directions of the sorting rollers 330 on both sides, and the rotation directions of the sorting rollers 330 are the same, that is, the flow direction of the loading and conveying part 100 is taken as the first direction, and the opposite direction of the first direction is taken as the second direction. Then, the contact position of the roller wing plate 321 and the sorting roller 330 on its left side is located in the first direction of the sorting roller 330, and the contact position of the roller wing plate 321 and the sorting roller 330 on its right side is located in the second direction of the sorting roller 330.

[0062] One end of the feeding conveying part 100 is located at the feeding end of the sorting part 300. When the sorting roller 330 rotates, the corrugated paperboard moves on the sorting roller 330 to Figure 1 For example, when the sorting roller 330 is at the top of its track, the roller wing 321 contacts the sorting roller 330, and the roller wing 321 drives the sorting roller 330 to rotate, and the corrugated cardboard moves along the conveying direction of the feeding conveying part 100; when the sorting roller 330 descends, the sorting roller 330 and the roller wing 321 are separated, and the sorting roller 330 descends to the bottom of the sorting bracket 310, and the corrugated cardboard falls onto the sorting roller 320. At this time, when the sorting roller 320 rotates, the sorting roller 320 drives the corrugated cardboard to move in a direction perpendicular to the feeding conveying part 100, thereby completing the sorting of the corrugated cardboard.

[0063] As a preferred implementation in the embodiment, the control unit 400 is a computer or an industrial computer. The control unit 400 performs the following steps when obtaining the surface quality or size of the corrugated paperboard:

[0064] S1, acquiring image information of a linear laser scanning a corrugated cardboard in real time based on the image acquisition module 230;

[0065] S2, obtaining the thickness of the corrugated paperboard based on the image information of the laser on the corrugated paperboard;

[0066] S3, obtaining a first size of the corrugated paperboard based on the time taken for the laser to scan across the corrugated paperboard;

[0067] S4, obtaining a second size of the corrugated paperboard based on the laser length on the corrugated paperboard and the thickness of the corrugated paperboard;

[0068] S5. Obtain the surface quality of corrugated cardboard based on laser straightness.

[0069] Specifically, in this embodiment, the corrugated cardboard passes under the 200 driven by the 100. When the edge of the corrugated cardboard contacts the edge of the corrugated cardboard for the first time, the image acquisition module 230 records the image information at this time, which is recorded as the first image. After a preset time, the image acquisition module 230 obtains the image of the corrugated cardboard, which is recorded as the second image. In the second image, there is a linear spot on the surface of the corrugated cardboard. When the linear laser contacts the edge of the corrugated cardboard for the second time, the image acquisition module 230 obtains the image at this time, which is recorded as the third image. At the same time, when there is a linear laser on the corrugated cardboard, the 400 also detects the straightness of the linear laser in real time to detect whether the linear laser is bent.

[0070] In step S2, the 400 calculates the thickness of the corrugated board based on the second image, specifically, as follows Figure 6 As shown, in the second image, there are two light spots, a first light spot and a second light spot. The first light spot is the light spot on the conveyor line, and the second light spot is the light spot on the corrugated cardboard. Since the relative position of the conveyor line, the linear laser 220 and the image acquisition module 230 does not change, the distance between the first light spot and the central axis of the image acquisition module 230 is known, denoted as A, and the angle between the light curtain of the linear laser and the central axis is known, denoted as α. The pixel distance between the first light spot and the center point of the image in the second image is a, and the ratio of the pixel distance to the actual distance in the second image is a / A, that is, the actual distance between the first light spot and the second light spot is M, and the pixel distance between the first light spot and the second light spot in the second image is m, and the actual distance between the first light spot and the second light spot is Am / a. The thickness of the corrugated cardboard is as shown in formula (1):

[0071]

[0072] Where H is the thickness of the corrugated board.

[0073] In step S3, the first size of the corrugated board is calculated based on formula (2):

[0074] L = vt; Formula (2)

[0075] Wherein, L is the first dimension, v is the thickness of the conveyor line, and t is the interval time for the linear laser to pass through the two end edges of the corrugated cardboard.

[0076] In step S4, after calculating the thickness of the corrugated paperboard, the distance between the upper surface of the corrugated paperboard and the focus of the image acquisition module 230 can be calculated, and then the value of the second size is obtained according to the length of the second light spot in the second image, that is, the second size is calculated based on formula (3):

[0077]

[0078] Wherein, W is the second size, w is the length of the second light spot, h is the distance between the focus of the image acquisition module 230 and the conveying surface 100, and f is the focal length of the image acquisition module 230.

[0079] As a preferred implementation in this embodiment, Figure 1 As shown, the sorting device also includes:

[0080] The circulation conveying section 500 is located downstream of the sorting section 300. The circulation conveying section 500 is a conveyor belt structure, and is used to convey corrugated cardboard with qualified size and surface quality to the carton production line.

[0081] As a preferred implementation in this embodiment, Figure 1 As shown, the sorting device also includes:

[0082] The sorting and conveying section 600 is located at the side of the sorting section 300. The sorting section 300 conveys the corrugated cardboard whose size and surface quality do not meet the preset values ​​to the sorting and conveying section 600, and the sorting and conveying section 600 conveys it to the collection position. The sorting and conveying section 600 is a conveyor belt structure.

[0083] It should be noted that the first size and the second size are the length and width of the corrugated cardboard respectively, and the pixel distance and the length of the second light spot are the number of pixels. If the first light spot and the second light spot are both straight lines in the second image, the number of pixels occupied by the shortest line between the midpoint of the second image and the straight line where the first light spot is located is the pixel distance between the midpoint of the second image and the first light spot.

[0084] In step S5, the 230 acquires the image of the second light spot in real time. Since the optical axis of the 220 and the conveying surface of the 100 have a certain angle, when the surface of the corrugated cardboard is flat, the second light spot is a line. When there are potholes on the surface of the corrugated cardboard, that is, the surface of the corrugated cardboard is damaged, the second light spot will be distorted when passing through the damaged part, that is, the image of the second light spot in the second image is no longer a straight line. The distorted straight line does not meet the straightness requirement, thereby detecting the surface quality of the corrugated cardboard.
