Detailed Implementation

[0026] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] See Figures 1-4 This utility model discloses a wooden board sorting device, including a frame 30, a conveying assembly 10, and a sorting assembly 20. Both the conveying assembly 10 and the sorting assembly 20 can be installed on the frame 30 as the mounting base. The conveying assembly 10 can convey wooden boards at intervals along a conveying direction.

[0030] The sorting assembly 20 includes a sorting drive 50, sorting wheels 24, and a sorting belt 21. The end of the sorting belt 21 can be wound around the sorting wheel 24, and the sorting belt 21 rotates along with the sorting wheel 24 when it rotates. The sorting drive 50 can drive the sorting wheel 24 to rotate. In this embodiment, two sorting wheels 24 are provided, and the two ends of the same sorting belt 21 are respectively wound around the two sorting wheels 24. The sorting drive 50 can be a motor, which drives the sorting wheel 24 to rotate, thereby driving the sorting belt 21.

[0031] The sorting belt 21 is provided with multiple sorting pieces 22 and sliding guides. The sorting pieces 22 are distributed at intervals around the circumference of the sorting belt 21. The sorting pieces 22 can rotate from a first state that is flush with the conveying end face of the conveying mechanism to a second state that is at an angle to the conveying end face when the sorting belt 21 rotates. The interval between two adjacent sorting pieces 22 forms a sorting interval. Each sorting interval is provided with a corresponding sliding guide. The sliding guide is used to guide the wooden board of the sorting interval to slide along the sorting direction.

[0032] Based on the above structure, when using the wooden board sorting device of this utility model, multiple wooden boards can be fed at intervals from the previous station, and the conveying component 10 realizes the interval conveying of multiple wooden boards. The interval conveying of wooden boards referred to in this embodiment means that during the conveying process, there is a certain gap between two adjacent wooden boards on the conveying end face of the conveying component 10, so as to prevent the stacking of two wooden boards in front and behind in the conveying direction. The wooden boards can be placed on the conveying component 10 manually at intervals, or they can be intermittently fed from the previous station.

[0033] It should be noted that in this embodiment, the conveying direction is towards the width of the wooden board itself, while the removal direction of the wooden board is towards its length.

[0034] Since the wooden boards do not overlap after being fed at intervals, the surface of the boards can be inspected to check for defects. If defects are found, the boards need to be removed by the conveyor assembly 10 for later sorting.

[0035] However, since the conveying assembly 10 is continuously conveying wooden boards, removing the boards would require stopping the conveying assembly 10, which would affect the conveying efficiency. Therefore, in this embodiment, a sorting assembly 20 is provided in the conveying direction of the conveying assembly 10. The sorting assembly 20 can be located at the beginning, end, or middle of the conveying assembly 10.

[0036] In this embodiment, the sorting component 20 can be positioned in the middle of the conveying component 10. When the wooden boards are conveyed, since the wooden boards are conveyed at intervals by the conveying component 10, the multiple sorting plates 22 of the sorting belt 21 can continuously drive the transmission rod 40 under the drive of the sorting wheel 24. When the sorting plate 22 rotates to the bottom of the sorting wheel 24, the sorting plate 22 is facing downwards. The sorting plate 22 rotates upwards around the sorting wheel 24. When it rotates to the first state where it is flush with the conveying end face of the conveying component 10, it can receive one of the wooden boards on the conveying end face of the conveying component 10. Then, under the action of the sorting belt 21, the sorting plate 22 continues to rotate around the sorting wheel 24 to the second state facing upwards. In this way, the wooden board can be pushed into the sorting interval. Similarly, each wooden board conveyed at intervals by the conveying component 10 can enter the sorting interval and be sorted by multiple sorting intervals.

[0037] If there are defects on the wooden board, at the sorting component 20, since each sorting interval is equipped with a corresponding sliding guide, the defective wooden board can be extracted through the sorting interval. At this time, the wooden board is restricted by the sorting interval and will not shift during the extraction process. At the same time, the sliding guide can also guide the wooden board to be extracted smoothly, reducing the jamming during the extraction process.

[0038] Unblemished wooden boards can continue to be conveyed by the sorting belt 21 of the sorting assembly 20. When they are conveyed to the sorting wheel 24 at the other end, the sorting plate 22 at the sorting wheel 24 can be guided downward by the sorting wheel 24 and rotated until it is flush with the conveying end face. The wooden board then falls back onto the conveying assembly 10 and continues to be conveyed by the conveying assembly 10, thereby realizing the sorting of wooden boards.

[0039] It should be noted that if the conveying end face of the conveying component 10 is horizontal, then the first state of the sorting plate 22 can be horizontal, and the second state can be vertical. If the conveying end face of the conveying component 10 is inclined, then the first state of the sorting plate 22 can be inclined, and the second state of the sorting plate 22 can be at an angle to the inclined first state. The specific settings can be selected according to actual needs.

[0040] Furthermore, the sliding guide in this embodiment includes a sliding wheel 23, which is set according to the sorting interval. When the defective wooden board is removed, the wooden board can be removed along its own length direction through the sorting interval. In this way, the bottom surface of the wooden board can be supported by the sliding wheel 23. When it is removed, the wooden board slides with the sliding wheel 23, thus guiding the wooden board to be removed smoothly.

[0041] Specifically, to facilitate the assembly of the sliding wheel 23, the sliding guide in this embodiment includes two connecting shafts. The two connecting shafts are connected to two adjacent sorting plates 22. The two ends of the sliding wheel 23 are rotatably connected to the two connecting shafts. In this way, the sliding wheel 23 is positioned and installed by the two connecting shafts connected to the adjacent sorting plates 22, so that the installation position of the sliding wheel 23 corresponds to the sorting interval. The wooden board is guided by the sliding wheel 23, and its width direction can be limited by the two sorting plates 22, while its length direction can be guided and pulled away by the sliding wheel 23. This prevents the wooden board from deflecting during the removal process.

[0042] Of course, in addition to using the sliding wheel 23 mentioned above, the sliding guide can also be a ball bearing structure set at the position of two adjacent sorting intervals on the sorting belt 21, so as to guide the removal of the wooden board by the ball bearing structure.

[0043] Furthermore, in this embodiment, the sorting belt 21 includes a chain, and the corresponding sorting wheel 24 includes a sprocket. During assembly, the chain is wound around the sprocket, and the sorting piece 22 is connected to the chain link.

[0044] This allows for easy installation of different sorting plates 22 corresponding to different chain links, simplifying assembly. Compared to using a transmission belt as the drive belt, this embodiment uses a transmission chain, which has a certain degree of rigidity, resulting in better support.

[0045] Furthermore, both sides of the sorting plate 22 are provided with guide ramps. When the sorting plate 22 rotates from the first state to the second state, the guide ramp on one side of the sorting plate 22 can exert a decomposed upward pushing force on the side of the wooden board, so that the wooden board can be stably pushed into the sorting interval. When the sorting plate 22 rotates from the second state to the first state, the guide ramp on the other side of the sorting plate 22 can exert a sorting forward pushing force on the side of the wooden board, tending the wooden board to fall stably onto the conveying end face of the conveying assembly 10.

[0046] Furthermore, the conveying assembly 10 is equipped with a wooden board detection component, which is used to detect defects on the wooden board and send a detection signal. The wooden board detection component can be a camera, infrared detector, etc. It can automatically detect the surface of the wooden board to determine whether it is a defective wooden board. If it is a defective wooden board, it can be extracted after entering the sorting interval.

[0047] Of course, in the absence of a wooden board inspection piece, inspection can also be carried out manually by visual inspection.

[0048] Furthermore, the conveying assembly 10 includes a conveying motor 13, a transmission shaft, and multiple conveyor belt mechanisms 11. The multiple conveyor belt mechanisms 11 are spaced apart on the frame 30. Specifically, the multiple conveyor belt mechanisms 11 can be spaced apart along the length of the wooden board. In this way, when the wooden board is conveyed, the length of the wooden board can be supported by multiple conveyor belt mechanisms 11. Different conveyor belt mechanisms 11 can support and convey at different sections along the length of the wooden board. In this way, the wooden board is conveyed at all positions, the conveying structure is stable, and the deviation that occurs during the conveying process is reduced.

[0049] Specifically, the conveyor belt mechanism 11 includes a conveyor belt and conveyor wheels, with the conveyor belt wound around the conveyor wheels; the conveyor wheels of each conveyor belt mechanism 11 are connected by a transmission shaft; the conveyor motor 13 can drive the transmission shaft 14 to rotate; based on this structure, the transmission motor 13 drives the transmission shaft 14 to rotate, and the rotation of the transmission shaft 14 can drive the conveyor wheels of each conveyor belt mechanism 11 to rotate synchronously, so that the transmission speed of each conveyor belt mechanism 11 is consistent, preventing differential speed due to inconsistent transmission speeds of each conveyor belt mechanism 11.

[0050] Of course, based on this structure, a sorting component 20 is provided between two adjacent conveyor belt mechanisms 11. In this way, the planks are transported in segments by different conveyor belt mechanisms 11 at different positions along their length. When the planks are transported to the corresponding sorting component 20, they are sorted at the corresponding positions by the sorting plates 22 on the sorting belt 21. The planks are sorted and transported at different sorting intervals. There are sorting intervals at different positions along the length of the planks to limit the width direction, which prevents the planks from swaying in the length direction. At the same time, when the planks are removed, there are sliding guides at different positions along the length of the planks to guide them, making the removal process smoother.

[0051] Similarly, the sorting wheels 24 of each sorting component 20 are connected via transmission rods 40; the sorting drive component 50 drives the transmission rods 40. The sorting drive component 50 drives the transmission rods 40 to rotate, and the rotation of the transmission rods 40 drives the conveyor wheels of each conveyor belt mechanism 11 to rotate synchronously. In this way, the conveyor belt transmission speed of each conveyor belt mechanism 11 is consistent, preventing differential speeds caused by inconsistent transmission speeds among the various conveyor belt mechanisms 11.

[0052] Furthermore, a guiding conveying mechanism 12 is provided between two adjacent conveyor belts, and the guiding conveying mechanism 12 and the sorting assembly 20 are distributed sequentially in the conveying direction; the guiding conveying mechanism 12 has a first guiding slope 121 and a second guiding slope 122 at both ends in the conveying direction. The first guiding slope 121 is used to guide the wooden board on the conveyor belt mechanism 11 to the guiding conveying mechanism 12, and the second guiding slope 122 is used to guide the wooden board of the conveying mechanism 12 to the sorting piece 22.

[0053] Specifically, the guiding conveyor mechanism 12 includes a guide belt 123, a guide frame 124, and two guide wheels. One end of the guide frame 124 is an upward-sloping guide plate, and the other end is a downward-sloping guide plate. A horizontal guide plate is located between the two guide plates. The guide belt 123 is wound around the guide frame 124. The guide plate at one end guides the guide belt 123 at one end to form a first guiding slope 121, and the guide plate at the other end guides the guide belt 123 at the other end to form a second guiding slope 122. The guide belt 123 is located on the horizontal guide plate to form a horizontal guiding surface. When the wooden board is conveyed by the conveyor belt mechanism 11 to the first guiding slope 121 of the guiding conveyor mechanism 12, the first guiding slope 121 guides the wooden board to move upward to the horizontal guiding surface, so that it can be separated from the conveying end face of the conveyor belt mechanism 11. Then, it is conveyed to the sorting interval by the second guiding slope 122, and the second guiding slope 122 guides the wooden board downward to facilitate its entry into the sorting interval.

[0054] Furthermore, the conveyor belt is provided with multiple spacer wheels 111, which are spaced apart in the conveying direction. In this way, the multiple spacer wheels 111 can separate two adjacent wooden boards in the conveying direction, preventing the wooden boards from stacking during the conveying process.

[0055] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
