Description

Technical Field

[0001] This invention relates to the field of saw blade machine technology, and more specifically to a saw blade movable edge-cleaning saw. Background Technology

[0002] A log is cut into planks of varying or uniform thickness by a multi-blade saw. The planks are then manually fed into an edge-trimming saw by aligning them with an infrared beam, where they are cut into standard sizes.

[0003] Currently, most intelligent edge trimming saws on the market use saw blades with fixed specifications. These fixed specifications are used when the wood board enters the scanning area. The image obtained through visual scanning is used to cut the board to the customer's desired specifications based on the cutting specifications set in the original vision software, using a combination method and adhering to the principle of maximizing the board's size. For example, the "Intelligent Edge Trimming Saw with Single-Sided Push-Again Board" disclosed in patent number CN218195701U uses a set of saw blades to cut the wood board. The number and distribution of these saw blades can be customized to adjust the size of the cut board according to actual needs.

[0004] The specifications of the cut plate are fixed and cannot be changed arbitrarily. If changes are needed, the spacer that fixes the saw blade must be changed, which is quite troublesome. Summary of the Invention

The correction pressure roller assembly is used to press the board when the correction assembly is working.

[0011] Preferably, the feeding pressure roller assembly includes a first support plate and a first electric lifting drive assembly. The first support plate is movably connected with a first pressure roller group and a brush. The first electric lifting drive assembly is used to drive the first support plate to move up and down towards or away from the wooden board on the feeding assembly. The limiting plate in the feeding assembly used to control the size of its output opening is fixed to the first support plate.

[0012] Preferably, the correction roller assembly includes a second support plate and a second electric lifting drive assembly.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: A type of saw blade movable edge trimming saw, such as Figure 1 As shown, it includes: The system comprises a feeding assembly 1, a conveying assembly, and a sawing assembly. The feeding assembly 1 transports the wooden boards onto the feeding assembly. The conveying assembly is equipped with a vision recognition system 2 and a correction assembly. The vision recognition system 2 takes pictures of the wooden boards paused within the conveying assembly and transmits the images to an industrial control computer. AI software analyzes the images and calculates the maximum width of the cut board. The maximum width line is a parallel line. Based on the board cutting specifications set in the interface, the lines within the maximum width are distributed according to the board cutting specifications through a combination method to obtain the cutting scheme with the highest utilization rate. The correction assembly performs calculations to correct the posture of the wooden boards, facilitating subsequent cutting. The above content is prior art in this field, and the specific structure will not be described in detail.

[0021] like Figure 1 As shown, the sawing assembly includes at least two sets of sawing moving components 3. The specific number of sawing moving components 3 can be automatically adjusted according to the requirements. Multiple sets of sawing moving components 3 located on the same side of the wood board are arranged along the forward direction of the wood board to avoid interference between adjacent sawing moving components 3. like Figure 2 As shown, the sawing moving assembly 3 includes a relatively fixed support base 33, a long-shaft motor 31, a saw blade 32, a transmission screw 34, a servo motor 35, and a slide 36. The transmission screw 34, servo motor 35, and slide 36 form a screw drive structure. This screw drive structure drives the long-shaft motor 31 to move along the axis of the long-shaft motor 31 (relatively perpendicular to the forward direction of the wooden board). The support base 33 has a hollow design to reduce weight. The axis of the transmission screw 34 is parallel to the axis of the transmission shaft of the long-shaft motor 31. The transmission screw 34 is rotatably connected to the support base 33. The output end of the servo motor 35 is connected to the transmission screw 34 via a coupling. The slide 36 moves linearly along the axis of the transmission screw 34 on the support base 33 via a slider rail. The transmission screw 34 is threadedly connected to the slide 36. The long-shaft motor 31 can be a long-shaft permanent magnet motor and is fixed on the slide 36. The rotation plane of the saw blade 32 is exactly the same as the forward direction of the wooden board.

[0022] like Figures 3-5As shown, multiple sets of correction components are provided, which are relatively distributed on the left and right sides of the wooden board. Each side of the wooden board has at least two sets of correction components, which can be two, three, or more. The correction components include correction clamps 4 and lateral movement devices 41. The correction clamps 4 are arranged vertically. The lateral movement devices 41 can use a lead screw transmission structure driven by a servo motor to achieve high-precision movement. The correction clamps 4 are installed at the output end of the lateral movement devices 41. The lateral movement devices 41 are used to drive the correction clamps 4 to move on the horizontal plane. Four sets of correction components are arranged relatively on the left and right sides of the wooden board, with two sets on each side. After the feeding component 1 conveys the wooden board on it into the conveying component and calculates through the vision recognition system 2, the lateral movement devices 41 drive the correction clamps 4 to abut against the edge of the wooden board. The wooden board 4 is corrected by the different extension and retraction amounts of the four sets of lateral movement devices 41.

[0023] This solution employs a combination of a correction component and a sawing movement component 3. Compared to existing technologies where the correction component pushes the wood board to align with a fixed sawing component, resulting in a fixed board size, this solution uses a movable sawing movement component 3, which can accommodate boards of any width. This is a decisive advantage for factories undertaking diverse, small-batch, and personalized orders, allowing for rapid response to changes in market demand without any hardware adjustments.

[0024] The material conveying assembly is also equipped with a feeding pressure roller assembly 5, a sawing pressure roller assembly 6, and a correction pressure roller assembly 7. The feeding pressure roller assembly 5 is located upstream of the sawing assembly, the sawing pressure roller assembly 6 is used in conjunction with the sawing assembly, and the correction pressure roller assembly 7 is used in conjunction with the correction assembly.

[0025] like Figure 6 As shown, the feeding roller assembly 5 includes two sets of parallel first support plates 51 and a first electric lifting drive assembly. The first electric lifting drive assembly includes a first reduction gear set 53 and a first rack 54. The input end of the first reduction gear set 53 is connected to a first motor to provide power. The first rack 54 is vertically fixed on the corresponding first support plates 51. The gear at the output end of the first reduction gear set 53 meshes with the first rack 54. Through the cooperation of the first reduction gear set 53 and the first rack 54, the two sets of first support plates 51 are driven to move vertically and synchronously. The first support plates 51 are guided to move vertically and linearly under the action of the first slider rail assembly 52. The limiting plate 55 is a component of the feeding assembly 1. The lifting and lowering of the limiting plate 55 adjusts the distance between its lower surface and the upper surface of the feeding assembly, thereby accommodating wooden boards of different thicknesses. The limiting plate 55 is also fixed on the first support plate 51.

[0026] A first pressure roller assembly 56 and a brush 57 are horizontally arranged on the first support plate 51. A rotary power mechanism for driving the brush 57 to rotate relative to the first support plate 51 is also installed on the first support plate 51. The first pressure roller assembly 56 is arranged on both the front and rear sides of the brush 57.

[0027] The first pressure roller assembly 56 is rotatable and will not hinder the forward movement of the wooden board during the pressing process. The first pressure roller assembly 56 slides vertically within a certain range relative to the first support plate 51 in the vertical direction (consistent with the lifting direction of the first support plate 51). A first return spring is provided between the first pressure roller assembly 56 and the first support plate 51. The first return spring pushes the first pressure roller assembly 56 to descend to the lower limit position relative to the first support plate 51.

[0028] A first pressure roller group 56 and a brush 57 are movably connected between the two sets of first support plates 51. The first electric lifting drive assembly is used to drive the first support plate 51 to lift and move closer to or away from the wooden board on the material conveying assembly. A first sensor 58 (which can be a reflective photoelectric sensor) is also installed on the first support plate 51 to determine whether there is a wooden board below.

[0029] like Figure 8 As shown, the correction roller assembly 7 includes two parallel second support plates 72 and a second electric lifting drive assembly. The second electric lifting drive assembly includes a second reduction gear set 76 and a second rack 75. The input end of the second reduction gear set 76 is connected to a second motor to provide power. The second rack 75 is vertically fixed on the corresponding second support plates 72. The gear at the output end of the second reduction gear set 76 meshes with the second rack 75. Through the cooperation of the second reduction gear set 76 and the second rack 75, the two second support plates 72 are driven to move vertically and synchronously. The second support plates 72 are guided to move vertically and linearly under the action of the second slider rail assembly 71.

[0030] A row of horizontally arranged second pressure roller groups 74 is set between the two second support plates 72, and there are more than two sets of second pressure roller groups 74.

[0031] The second pressure roller assembly 74 is rotatable and will not hinder the forward movement of the wooden board during the pressing process. The second pressure roller assembly 74 slides vertically within a certain range relative to the second support plate 72 in the vertical direction (consistent with the lifting direction of the second support plate 72). A second return spring is provided between the second pressure roller assembly 74 and the second support plate 72. The second return spring pushes the second pressure roller assembly 74 to descend to the lower limit position relative to the second support plate 72.

[0032] The second electric lifting drive assembly is used to drive the second support plate 72 to move closer to or away from the wooden board on the conveying assembly; and the second support plate 72 is also equipped with a second sensor (not shown in the attached figure and may be a reflective photoelectric sensor), which determines whether there is a wooden board below.

[0033] The alignment roller assembly 7 includes a second support plate 72 and a second electric lifting drive assembly. A group of one or more second roller sets 54 are movably connected to the second support plate 72 and are arranged horizontally in parallel along the conveying direction of the conveying assembly. The second electric lifting drive assembly is used to drive the second support plate 72 to lift or move closer to or away from the wooden board on the conveying assembly.

[0034] like Figure 7 As shown, the sawing pressure roller assembly 6 includes a base 64 and a third electric lifting drive assembly for driving the base 64 to move closer to or away from the wooden board on the conveying assembly. The base 64 is connected to a corresponding fulcrum assembly 66 via an elastic telescopic rod 69. The fulcrum assembly 66 has two or more sets and is arranged along the conveying direction of the conveying assembly.

[0035] The circumferential surface of the roller of the pivot assembly 66 is machined with annular tooth structure, and multiple annular tooth structures are arranged at intervals along the axial direction of the roller. The third electric lifting drive assembly can be a vertically arranged screw drive assembly or an electric push rod. The third electric lifting drive assembly can also be as follows: Figure 7 As shown, the system includes several screw jacks 61 arranged horizontally along the length of the base 64. Multiple sets of screw jacks 61 are evenly arranged relative to the length of the base 64 (consistent with the conveying direction of the material conveying assembly). One set of screw jacks 61 is powered by a third motor. Two adjacent screw jacks 61 are synchronously driven through a power connecting rod 63. The output end of each screw jack 61 is connected to the base 64, thereby enabling the base 64 to be lifted vertically.

[0036] The elastic telescopic rod 69 can automatically extend and retract, tending to lengthen under normal conditions. Each set of fulcrum components 66 is connected to the base 64 below through two elastic telescopic rods 69, and multiple sets of fulcrum components 66 are arranged along the length of the base 64.

[0037] A third sensor 65 (which can be a reflective photoelectric sensor) is also installed on the base 64. The third sensor 65 is used to monitor the change in the elastic telescopic rod 69 and thus determine whether the fulcrum assembly 66 is pressing down on a wooden board.

[0038] The fulcrum assembly 66 includes a support and a roller horizontally rotatably connected to the support. The roller can be driven to rotate by a power assembly. The circumferential surface of the roller is machined with annular toothed structures, and multiple annular toothed structures are arranged along the axial spacing of the roller, with a certain distance between adjacent annular toothed structures to prevent skewing. The annular toothed structure on the circumferential surface of the roller can prevent slippage.

[0039] When the fulcrum assembly 66 and the second pressure roller group 54 are pressed down, they are misaligned with the sawing assembly and the correction assembly.

[0040] Working principle: Multiple vertically stacked band saw-cut wooden boards are placed in the feeding assembly 1. The feeding assembly 1 is an existing structure. Under the combined action of the conveying assembly and the limiting plate 55, the bottom wooden boards are conveyed forward one by one. The conveying assembly is used to drive the wooden boards to be horizontally conveyed forward to the sawing assembly for sawing and then output outward.

[0041] The thickness h of the wooden board can be manually input at a control center with a control panel (such as a touch screen), and the descent height of the feeding roller assembly 5, the sawing roller assembly 6, and the correction roller assembly 7 can be adaptively adjusted according to the thickness h of the wooden board.

[0042] The first electric lifting drive component drives the first support plate 51 to descend to the corresponding height according to the input wood thickness. During this process, the limiting plate 55 descends along with the material conveying component to form a space that adapts to the wood thickness h. At the same time, the space between the first pressure roller group 56 and the brush 57 and the material conveying component is just adapted to the wood thickness h. After the wooden board passes through the limiting plate 55, the first pressure roller assembly 56 presses down on the upper surface of the wooden board, and the rotation of the brush 57 cleans the wooden board to improve the accuracy of subsequent visual recognition. After detaching from the feeding pressure roller assembly 5, the wooden board continues to be conveyed forward to the area of ​​the correction pressure roller assembly 7.

[0043] like Figure 3 As shown, if the visual recognition system 2 calculates that the wood board is most suitable for cutting into two pieces, it controls the saw blades 32 of two sets of sawing moving components 3 to move to the set positions (corresponding to cutting line 1 and cutting line 2 respectively), the saw blades 32 of the third set of sawing moving components 3 to move to the set position (corresponding to cutting line 3), and the remaining sawing moving components 3 to move to the waiting position and not participate in the cutting work. During the process of the wood board moving from the feeding component, it is cut into two pieces by the saw blades 3 of the three sets of sawing moving components 3.

[0044] like Figure 4 As shown, if the visual recognition system 2 calculates that the wood board is most suitable for cutting into three pieces, it controls the saw blades 32 of two sets of sawing moving components 3 to move to the set positions (corresponding to cutting line 1 and cutting line 2 respectively), the saw blades 32 of the third and fourth sets of sawing moving components 3 to move to the set positions (corresponding to cutting line 3 and cutting line 4 respectively), and the remaining sawing moving components 3 move to the waiting position and do not participate in the cutting work. During the process of the wood board moving from the feeding component, it is cut into three pieces by the saw blades 3 of the four sets of sawing moving components 3.

[0045] like Figure 5As shown, if the visual recognition system 2 calculates that the wood board is most suitable for cutting into one piece, it controls the corresponding saw blades 32 of two sets of sawing moving components 3 to move to the set position (corresponding to cutting line 1 and cutting line 2 respectively), and the remaining sawing moving components 3 move to the waiting position and do not participate in the cutting work. During the process of the wood board moving from the feeding component, it is cut into one piece by the corresponding saw blades 3 of these two sets of sawing moving components 3.

[0046] The saw blade 32 of the sawing moving assembly 3 is adjustable, which can flexibly adapt to different sizes of wooden boards at the front and rear.

[0047] After the wooden board is detached from the feeding pressure roller assembly 5, the second sensor determines whether the wooden board has moved into position and controls the second electric lifting drive assembly to drive the second support plate 72 to descend to a set height, so that the second pressure roller assembly 74 on it presses down on the wooden board to prevent the wooden board from tilting upwards during forward conveying; before the subsequent correction assembly corrects the wooden board, the correction pressure roller assembly 7 is controlled to rise and reset, so that there is no resistance during the correction process, which can improve the accuracy of correction.

[0048] Before the sawing moving assembly 3 saws the wooden board, the third electric lifting drive assembly drives the base 64 to descend to a set height, so that multiple sets of fulcrum assemblies 66 press down on the wooden board. When the fulcrum assemblies 66 press down on the wooden board, they will cause the elastic telescopic rod 69 to shorten by a certain length, which is detected by the third sensor 65, and then it is determined whether the pressure is in place. After that, the sawing action is performed, and after a set time, the sawing pressure roller assembly 6 rises and resets.

[0049] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
