Description

Technical Field

[0001] The present invention relates to the technical field of box posture adjustment, and in particular to a conveying device for box posture adjustment. Background Art

[0002] In truck container unloading lines, workers typically manually move cartons onto chain conveyors or roller conveyors. A barcode reader at the back end then reads the barcode or QR code affixed to the cartons for identification and storage. To facilitate the barcode reader's scanner, workers must flip the cartons so that a specific surface (usually the conveying surface or side) faces upward.

[0003] To improve work efficiency, existing technologies use automated loading and unloading systems to replace manual unloading of cartons. However, most automated loading and unloading systems lack or struggle to simultaneously flip cartons while unloading. Therefore, a flipping device is required at the front end of the automated loading and unloading system to interface with the automatic barcode reading equipment at the back end. This allows for automated unloading without modifying the barcode reading equipment.

[0004] The existing turning equipment has a fixed direction for turning cartons, a single motion logic, and a limited movement path for cartons at a single station, so there is room for improvement. Summary of the Invention

[0033] Please refer to Figure 1-10 The present invention discloses a conveying device for adjusting the posture of a box. The device includes a conveying mechanism, an identification mechanism and a posture adjustment mechanism.

[0034] Please refer to the Figure 1-3 The conveying mechanism includes a frame and a roller conveyor line 1. The roller conveyor line 1 is mounted on the frame. The frame includes a front bracket 11, a connecting frame 12 and a rear bracket 13. The front bracket 11, the connecting frame 12 and the rear bracket 13 are fixedly connected in sequence along the conveying direction of the roller conveyor line 1. The front bracket 11 and the rear bracket 13 are both supported on the ground, and the connecting frame 12 is suspended in the air. The surface formed on the roller conveyor line 1 for conveying the box is the conveying surface. The box is placed on the conveying surface from the front bracket 11 and conveyed backward.

[0035] When two boxes enter the identification mechanism side by side in the width direction of the roller conveyor line 1, the two boxes will block each other, resulting in the identification mechanism being unable to fully identify both boxes. Therefore, before the boxes enter the identification mechanism, there should not be a situation where the two boxes are side by side in the width direction of the roller conveyor line 1.

[0036] In order to avoid the above situation, the conveying mechanism also includes a baffle 2 and a third drive assembly 3. The baffle 2 is arranged vertically and perpendicular to the conveying direction of the roller conveyor line 1. The third drive assembly 3 is arranged on the frame and connected to the baffle 2, which is used to drive the baffle 2 to rise and fall in the vertical direction, and then drive the baffle 2 to extend from below the conveying surface of the roller conveyor line 1 to the top, or to descend from above the conveying surface of the roller conveyor line 1 to the bottom. The baffle 2 deviates from the center line of the roller conveyor line 1 in the width direction of the roller conveyor line 1, so that when the baffle 2 extends above the conveying surface of the roller conveyor line 1, a space for only one box to pass is left above the conveying surface of the roller conveyor line 1.

[0037] Specifically, the portion of the roller conveyor line 1 located on the front bracket 11 includes a plurality of parallel and spaced long rollers 14. The baffle 2 can be arranged between any two adjacent long rollers 14 according to the needs of the blocking box. The shape of the baffle 2 can be rectangular, circular or other suitable shapes. In this embodiment, the baffle 2 is a rectangular plate. The third drive assembly 3 includes two rodless cylinders, and the cylinder bodies of the two rodless cylinders are vertically fixed on the front bracket 11 and are located below the long rollers 14. The pistons of the two rodless cylinders are respectively connected to both sides of the width direction of the baffle 2. When the baffle 2 needs to be raised, the pistons of the two rodless cylinders move upward at the same time, driving the baffle 2 to rise. When the baffle 2 needs to be lowered, the piston rods of the two rodless cylinders move downward at the same time, driving the baffle 2 to fall.

[0038] The lifting and lowering of the rodless cylinders can be controlled by a host computer, which can be the control system of the assembly line. That is, when unloading is carried out upstream of the conveying device with box posture adjustment of the present invention, unloading information is input into the control system. The control system controls the movement of the two rodless cylinders based on whether the unloading information shows two boxes side by side, thereby controlling the lifting and lowering of the baffle 2.

[0039] In a preferred embodiment of the present invention, the conveying mechanism further includes a detection component (not shown). The detection component is disposed on the frame and is in communication with the third drive assembly 3. The detection component is configured to, upon detecting that two boxes are being conveyed side by side on the roller conveyor line 1, extend the baffle 2 via the third drive assembly 3 above the conveying surface of the roller conveyor line 1 to block one of the two boxes.

[0040] The detection component can adopt two through-beam photoelectric sensors. The two through-beam photoelectric sensors are arranged at intervals along the width direction of the roller conveyor line 1 upstream of the baffle 2 along the conveying direction of the roller conveyor line 1, and the interval between the two is greater than the maximum width of the box. When one of the through-beam photoelectric sensors generates a signal and the other through-beam photoelectric sensor does not generate a signal, it indicates that there are no two boxes being conveyed side by side. The third drive component 3, that is, the rodless cylinder drives the baffle 2 to descend and keeps the baffle 2 in the lowered state. When both through-beam photoelectric sensors generate signals, it indicates that two boxes are being conveyed side by side on the roller conveyor line 1. The rodless cylinder drives the baffle 2 to rise and keeps the baffle 2 in the raised state.

[0041] Please refer to Figure 4 、 Figure 5 The recognition mechanism includes a first gantry 4, a recognition component and a control component. The first gantry 5 has a first inlet 417 and a first outlet 418 arranged along the conveying direction of the roller conveyor line 1. The recognition component includes a camera 415. The camera 415 is located between the first inlet 417 and the first outlet 418 in the conveying direction of the roller conveyor line 1. The camera 415 is communicated with the control component and is used to identify target features on each surface of the box. The control component is communicated with the posture adjustment mechanism and is used to determine the real-time posture of the box according to the position of the target feature, and control the posture adjustment mechanism to adjust the box to the target posture according to the real-time posture.

[0042] The first gantry 4 comprises two first frames 41. The first frames 41 include a first upper crossbeam 411, a first lower crossbeam 412, and two first legs 413. The two first legs 413 are vertically spaced apart. The first upper crossbeam 411 is fixedly connected between the upper ends of the two first legs 413. The first lower crossbeam 412 is fixedly connected between the middle and lower portions of the two first legs 413. The two first frames 41 are fixedly connected by a plurality of first longitudinal beams 414, giving the first gantry 4 an overall rectangular shape, with its width parallel to the conveying direction of the roller conveyor line 1. A first entrance 417 is formed between the first upper crossbeam 411 and the first lower crossbeam 412 of the first frame 41 near the front support 11. A first exit 418 is formed between the first upper crossbeam 411 and the first lower crossbeam 412 of the first frame 41 away from the front support 11. Boxes transported by the roller conveyor line 1 sequentially pass through the first entrance 417 and the first exit 418.

[0043] When the roller conveyor line 1 passes through the two first frames 41 , it passes between the first upper beam 411 and the first lower beam 412 , and the connecting frame 12 is located below the first gantry 4 .

[0044] The target features on the box include one or more of a QR code 122, a barcode, and tape 121. In other embodiments of the present invention, the target features on the box also include trademarks, patterns, warning signs, etc. In actual use, the target features can be selected according to the needs of box posture adjustment.

[0045] The function of cameras 415 is to identify target features on the box. Therefore, each side of the box must be within the field of view of at least one camera 415. In a preferred embodiment of the present invention, there are ten cameras 415. These ten cameras 415 are arranged in four vertical layers, with the cameras 415 on each layer at the same height.

[0046] There are two cameras 415 spaced apart in the first layer from top to bottom. The two cameras 415 are installed on the first upper beam 411 of the first frame 41 away from the front bracket 11, and their fields of view both include the top surface of the box.

[0047] The second layer is provided with four cameras 415. The four cameras 415 are respectively mounted on the four first legs 413, arranged in a rectangular shape, and their fields of view all include the top surface and one of the side surfaces of the box.

[0048] Two cameras 415 are arranged at intervals on the third layer. The two cameras 415 are respectively installed on the two first legs 413 of the first frame 41 away from the front bracket 11, and their fields of view include one side surface of the box.

[0049] Two cameras 415 are arranged at intervals on the fourth layer. Both cameras 415 are installed on the first lower crossbeam 412 of the first frame 41 away from the front bracket 11, and their fields of view include the bottom surface of the box.

[0050] By arranging the cameras 415 in four layers, it is possible to ensure that each surface of the box is identified, which is beneficial to improving the efficiency and accuracy of the identification mechanism in identifying target features.

[0051] It should be noted that, typically, the identification and storage of boxes is performed by a process downstream of the conveyor device for box posture adjustment of the present invention. However, this can also be accomplished by the camera 415 of the present invention. Therefore, in another embodiment of the present invention, the camera 415 is a camera 415 that can recognize the information contained in the barcode or QR code 122 and is communicatively connected to the database recorded during the identification and storage of boxes. Furthermore, the camera 415 can recognize target features on the box surface while also enabling the identification and storage of boxes.

[0052] To improve the adaptability of the conveying device for adjusting the box posture of the present invention to boxes of varying sizes, the control component includes a storage unit. The storage unit stores a box shape database, which includes dimensional data corresponding to various box types. The control component determines the box's real-time posture based on target characteristics and the corresponding dimensional data. Based on this real-time posture, the control component controls the posture adjustment mechanism to adjust the box to the target posture.

[0053] After the user inputs all the dimensional data of the box that needs to be adjusted into the shape database, the control component can directly call the dimensional data in the shape database when judging the real-time posture of the box, thereby being able to identify the real-time posture of the box more quickly, effectively improving the adaptability of the conveying device for box posture adjustment of the present invention to boxes of different sizes.

[0054] Please continue to refer to Figure 4 、 Figure 5 If the focal length of camera 415 is not adjustable, the position of camera 415 needs to be adjusted so that the surface of the box falls within the focal point of camera 415 in order for camera 415 to accurately identify the target features. Accordingly, the volume of first gantry 4 increases, occupying a larger space. Therefore, in order to reduce the space occupied by first gantry 4, in a preferred embodiment of the present invention, the recognition component further includes a plane mirror 416. Plane mirror 416 is disposed on first gantry 4. One or more cameras 415 include the box in their field of view through reflection from plane mirror 416.

[0055] Specifically, there are four plane mirrors 416. The first plane mirror 416 is mounted on the first upper crossbeam 411 of the first frame 41 near the front support 11. This allows light emitted from the box surface to be reflected by the plane mirror 416 before entering the two cameras 415 on the first layer. Following the same principle as the first plane mirror 416, the second and third plane mirrors 416 are mounted on the two first legs 413 of the first frame 41 near the front support 11, at the same height as the cameras 415 on the third layer, corresponding to the two cameras 415 on the third layer. The fourth plane mirror 416 is mounted on the first lower crossbeam 412 of the first frame 41 near the front support 11. The installation of the plane mirrors 416 allows the focus of the cameras 415 to be placed on the box surface without increasing the size of the first gantry 4, thereby reducing the space occupied by the first gantry 4 and increasing the field of view of the cameras 415.

[0056] Please refer to Figure 6 、 Figure 7 The posture adjustment mechanism includes a second gantry 5, a flip assembly and a rotation assembly. Figure 7 In order to more clearly show the internal structure of the posture adjustment mechanism, part of the structure of the second gantry 5 is hidden.

[0057] The second gantry 5 comprises two second frames 51. The second frames 51 include a second upper crossbeam 511, a second lower crossbeam 512, and two second legs 513. The two second legs 513 are vertically spaced apart. The second upper crossbeam 511 is fixedly connected between the upper ends of the two second legs 513. The second lower crossbeam 512 is fixedly connected between the middle and lower portions of the two second legs 513. The two second frames 51 are fixedly connected by a plurality of second longitudinal beams, giving the second gantry 5 an overall rectangular parallelepiped shape, with its width parallel to the conveying direction of the roller conveyor line 1. A second inlet 515 is formed between the second upper crossbeam 511 and the second lower crossbeam 512 of the second frame 51 near the front support 11. A second outlet 516 is formed between the first upper crossbeam 511 and the first lower crossbeam 512 of the second frame 51 away from the front support 11. The roller conveyor line 1 transports boxes through the first inlet 417, first outlet 418, second inlet 515, and second outlet 516. Furthermore, the rear support 13 is located below the second gantry 5 .

[0058] The flip assembly and the rotation assembly are located between the second inlet 515 and the second outlet 516 in the conveying direction of the roller conveyor line 1. The flip assembly is located above the roller conveyor line 1 and includes a clamp 6, a clamp plate 7, a first drive component 8, and a second drive component 9. There are two clamps 6. Each clamp 6 is provided with a clamp plate 7. The first drive component 8 is used to drive the two clamps 6 to move closer to or away from each other so that the clamp plates 7 clamp or release the box. The second drive component 9 is used to drive the clamp plates 7 to rotate around their axis horizontally and perpendicular to the roller conveyor line 1, thereby driving the box to flip.

[0059] There are two first driving components 8, and both are arranged on the second gantry 5. A clamp 6 is connected to each first driving component 8. The end of each clamp 6 away from the clamp 6 is connected to a clamp 7 and a second driving component 9. The two clamps 7 are opposite each other, and the box passes between the two clamps 7. The first driving component 8 is used to drive the clamp 6 connected thereto to move in a horizontal direction and perpendicular to the conveying direction of the roller conveyor line 1, so that the two clamps 7 are close to or away from each other, thereby clamping or releasing the box. The second driving component 9 is located on the side of the clamp 7 away from the other clamp 7, and is used to drive the clamp 7 to rotate around its own axis so that the box clamped between the two clamps 7 is flipped.

[0060] Specifically, both first drive components 8 can adopt rodless cylinders, the length direction of the cylinder body of which is horizontal and perpendicular to the conveying direction of the roller conveyor line 1, and the pistons are respectively connected to a clamp 6. The first drive component 8 is arranged on the second upper crossbeam 511 near the front bracket 11. The clamp 6 is in the shape of a vertically arranged rectangular plate, and its lower end is set to be circular, which is convenient for installing other components thereon. The splint 7 can be of any shape, and its function is to tighten the box body and drive the box body to flip over. In this embodiment, the splint 7 is a circular plate. The first drive component 8 can adopt a servo motor. The outer shell of the first drive component 8 is fixedly connected to the side of the lower end of the clamp 6 away from the splint 7, and the output shaft passes through the clamp 6 and is fixedly connected to the splint 7, so that the splint 7 can be driven to rotate.

[0061] When the box enters between the two clamps 7 and needs to be flipped, the two first drive components 8 each drive the two clamps 6 toward each other, thereby driving the two clamps 7 toward each other. After the two clamps 7 clamp the box, the two second drive components 9 each drive the two clamps 7 to rotate in the same direction, ultimately causing the box to flip. After the box flips, the two second drive components 9 stop, and the two first drive components 8 each drive the two clamps 6 in opposite directions, causing the two clamps 7 to release the box.

[0062] The process of the clamping plate 7 driving the box to flip takes a certain amount of time. In order to improve the efficiency of the box flipping, in a preferred embodiment of the present invention, the posture adjustment mechanism also includes a push plate 10. The push plate 10 is arranged on the second gantry 5 and is located above the clamping plate 7. It is used to block the box with the same height as the push plate 10 or higher than the push plate 10, so as to flip the box.

[0063] Specifically, a mounting rod 101 is fixedly connected between the two second upper crossbeams 511. A slide rail 102 is fixedly connected to the lower side of the mounting rod 101. A slider 103 is slidably connected to the slide rail 102. The length direction of the slide rail 102 is parallel to the conveying direction of the roller conveyor line 1 and is located above the two clamping plates 7. Two push rods 105 are fixedly connected to the slider 103. One end of each push rod 105 is fixedly connected to the slider 103, and the other end extends in a direction opposite to the conveying direction of the roller conveyor line 1. The push plate 10 is fixedly connected to the ends of the two push rods 105 away from the slider 103.

[0064] Two connecting rods 104 are provided on the underside of the slider 103. One end of each connecting rod 104 is hinged to the slider 103, and the other end is hinged to the two clamps 6. When the two clamps 6 move in opposite directions, the two connecting rods 104 drive the slider 103 to slide in the direction opposite to the conveying direction of the roller conveyor 1. In turn, the two push rods 105 push the push plate 10 in the direction opposite to the conveying direction of the roller conveyor 1. This causes the box, which is at the same height as or higher than the push plate 10, to flip due to inertia and the obstruction of the push plate 10.

[0065] Furthermore, when the two clamps 6 are in the closest position to each other, the push plate 10 is flush with the side of the clamps 6 closest to the front bracket 11, so that no matter how far away the two clamps 6 are from each other, the push plate 10 can always play a blocking role.

[0066] If the box body with the same height as the push plate 10 or higher than the push plate 10 is turned over by the clamping plate 7, it will take more time. Therefore, by arranging the push plate 10, the efficiency of the box body turning over can be effectively improved.

[0067] Please refer to Figure 7-9 The rotating assembly includes a tray 111, a lifting component 112, and a rotating component 113. The lifting component 112 is set on the second gantry 5 and is connected to the tray 111. It is used to drive the tray 111 to rise and fall, so that it is higher or lower than the conveying surface of the roller conveyor line 1. The rotating component 113 is fixedly connected to the lifting component 112 and is connected to the tray 111. When the tray 111 is higher than the conveying surface of the roller conveyor line 1, it drives the tray 111 to rotate around its own vertical axis, thereby driving the box to rotate.

[0068] Specifically, the portion of the roller conveyor line 1 located on the rear support 13 includes two rows of short rollers 15 arranged side by side. The two rows of short rollers 15 correspond to each other, and the corresponding two short rollers 15 are coaxial and spaced apart. The tray 111 is shaped like a well, allowing it to freely pass through the gap between two adjacent short rollers 15 in the same row, as well as the gap between two rows of segment rollers, and rise and fall without being blocked.

[0069] Two support rods 115 are fixedly connected between the two second lower cross beams 512. The lifting component 112 can be a pneumatic cylinder, an oil cylinder or other components. In this embodiment, the lifting component 112 is a pneumatic cylinder. The cylinder body of the cylinder is fixedly connected to the support rod 115, and the piston rod is arranged vertically. The end of the cylinder piston rod is fixedly connected to a connecting plate 114. The connecting plate 114 is arranged horizontally. The rotating component 113 adopts a servo motor. The housing of the servo motor is fixedly connected to the side of the connecting plate 114 close to the cylinder. The output shaft of the servo motor passes through the connecting plate 114 and is fixedly connected to the lower side of the tray 111. In order to improve the stability of the tray 111 during lifting and lowering, there are two cylinders, and the two cylinders are symmetrically installed on both sides of the servo motor housing.

[0070] The conveying device for adjusting the posture of boxes of the present invention operates as follows: During unloading, boxes first enter the conveying mechanism. The boxes are first conveyed on the portion of the roller conveyor line 1 located above the front bracket 11. Before the boxes pass through the baffle 2, a determination is made as to whether two boxes are located side by side. If two boxes are located side by side, the baffle 2 is raised, allowing only one box to enter the recognition mechanism at a time. After the boxes enter the recognition mechanism, multiple cameras 415 identify target features on each surface of the boxes, and the control component determines the real-time posture of the boxes based on the locations of the target features. After the boxes enter the posture adjustment mechanism, the control component controls the posture adjustment mechanism based on the real-time posture of the boxes to adjust the posture of the boxes to the target posture. When the boxes need to be flipped, the clamping plates 7 can be used to clamp the boxes, which are then rotated to cause the boxes to flip. Boxes whose height is equal to or higher than that of the push plate 10 can be flipped directly due to being blocked by the push plate 10. When the box needs to rotate, the pneumatic cylinder pushes the servo motor and tray 111 to rise, lifting the box off the conveying surface of roller conveyor line 1. The servo motor then drives the tray 111 to rotate, which in turn drives the box to rotate. After the box rotates, the piston rod of the pneumatic cylinder retracts, driving the servo motor and tray 111 downward, causing the tray 111 to drop below the conveying surface of roller conveyor line 1, allowing the box to return to the conveying surface of roller conveyor line 1.

[0071] The following uses a box with a QR code 122 pasted on its surface and sealed with tape 121 on both sides as an example to illustrate the adjustment logic of the conveying device for box posture adjustment of the present invention for different real-time postures of boxes. Figure 10In the diagram, ±X represents the left and right sides of the box, ±Y represents the front and back sides of the box, and ±Z represents the top and bottom sides of the box. The target posture to be adjusted is that the QR code 122 is located on the top side of the box and the tape 121 is located on the front or back side of the box.

[0073]

[0074] Compared to existing technologies, the conveying device for adjusting the box's posture can formulate different adjustment strategies based on the box's real-time posture, adjusting the box to a target posture. Furthermore, because the user can input all the dimensional data of the box requiring posture adjustment into the shape database, the control component can directly access the dimensional data in the shape database when determining the box's real-time posture, enabling faster identification of the box's real-time posture. This effectively improves the adaptability of the conveying device for adjusting the box's posture to boxes of varying sizes.

[0075] In addition, the conveying device for adjusting the posture of the box of the present invention can make the focus of the camera 415 fall on the surface of the box without increasing the volume of the first gantry 4 through the cooperation of the camera 415 and the plane mirror 416, thereby helping to compress the space occupied by the first gantry 4, making it easier to deploy the conveying device for adjusting the posture of the box in venues with different application scenarios, and at the same time increasing the field of view of the camera 415.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
