Description

Technical Field

[0001] This invention relates to the field of furniture processing technology, and in particular to a wood sorting and stacking device for furniture processing. Background Technology

[0002] In the furniture manufacturing process, the use of wood sorting and stacking devices is of paramount importance. Furniture manufacturing involves various types, specifications, and materials of wood. From the rough processing of logs to the production of fine components, each type of wood has its specific uses and processing requirements. Without sorting and stacking, different types of wood are mixed together, which not only consumes a lot of time and effort in identifying and selecting them later, reducing production efficiency, but may also affect the quality and stability of the finished furniture by using unsuitable wood. For example, using wood with low hardness and easy deformation in load-bearing structural parts. Moreover, mixing wood of different specifications can easily cause surface damage and deformation of the wood during handling and storage, increasing the scrap rate. Wood sorting and stacking devices can accurately classify and store wood according to its material, size, thickness, and other key characteristics, making the entire processing process smoother and more efficient. This effectively ensures the quality and cost control of furniture manufacturing and is an indispensable key piece of equipment for improving the overall efficiency of furniture manufacturing.

[0003] The existing technology CN219383394U describes a wood sorting and stacking device for furniture processing, which includes a rectangular frame with several inclined fixed column groups arranged within the frame. Each fixed column group includes two symmetrically arranged and inclined fixed columns. A sliding support mechanism is slidably mounted on the fixed columns. A stop structure is connected to the sliding support mechanism. The sliding support mechanism includes a slider with a sliding channel, a support column on one side of the slider, a rectangular insertion hole at the end of the support column, and a locking bolt on the bottom side of the support column. By setting fixed column groups on the rectangular frame and installing sliding support mechanisms on the fixed column groups, the problem of inconvenience in retrieving wood during the use of existing stacking racks is solved. At the same time, the number of sliding support mechanisms installed can be adjusted to meet the classification quantity requirements, and the distance between two sliding support mechanisms can be adjusted to meet the placement requirements of wood of different lengths.

[0004] However, in the furniture processing process, the wood sorting and stacking device used needs to bear the task of stacking relatively heavy wood. In the existing wood sorting and stacking device, the part that holds the wood may bend or even break when stacking relatively heavy wood because it cannot bear the weight of the wood. Once the part that holds the wood bends or breaks, it will directly affect the stability of the entire stacking structure, and thus cause the stacking structure to fail. Summary of the Invention

[0005] The purpose of this invention is to provide a wood sorting and stacking device for furniture processing, which aims to solve the problem that in the existing wood sorting and stacking devices used in furniture processing, which need to bear the task of stacking heavy wood, the wood placement part of the existing wood sorting and stacking device may bend or even break when stacking heavy wood because it cannot bear the weight of the wood. Once the wood placement part bends or breaks, it will directly affect the stability of the entire stacking structure, and thus cause the stacking structure to fail.

Detailed Implementation

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] Please see Figures 1 to 12 This invention provides a wood sorting and stacking device for furniture processing, including a protective cover 1 and a movable base 2. The protective cover 1 has slides 3 at its inner top and bottom. A first dual-axis motor 4 is located in the middle of the slide 3. Each output end of the first dual-axis motor 4 has a first screw 5. Each end of the slide 3 has a first groove 6, and a first slider 7 is slidably disposed within each first groove 6. The first screw 5 is threaded into the first slider 7. A lifting sleeve 8 is located above the first slider 7. A second dual-axis motor 9 and a third dual-axis motor 10 are located in the middle of the movable base 2. Each output end of the second dual-axis motor 9 has a second screw 11. The third dual-axis motor 10... Both output ends of the movable seat 2 are provided with a third screw 12. Both ends of the movable seat 2 have a second slide groove 13 and a third slide groove 14. A second slider 15 is slidably disposed in the second slide groove 13, and the second screw 11 is threaded in the second slider 15. A third slider 16 is slidably disposed in the third slide groove 14, and the third screw 12 is threaded in the third slider 16. Stacking components are provided on both the second slider 15 and the third slider 16, and the third slider 16 is higher than the second slider 15. Each stacking component is inserted into the corresponding lifting sleeve 8. A support mechanism is provided below the movable seat 2, and the movable seat 2 is slidably disposed in the protective cover 1 through the support mechanism.

[0033] In this embodiment, the slide block 3, the first dual-axis motor 4, the first screw 5, the first slider 7, and the lifting sleeve 8, etc., are arranged at the top and bottom of the protective cover 1. Together with the second dual-axis motor 9, the third dual-axis motor 10, the second screw 11, the third screw 12, the second slider 15, the third slider 16, and the stacking components on the moving base 2, the flexible adjustment and classified stacking of wood stacking position are realized. This design enables the device to accurately position and stack wood according to different specifications and types, improving the efficiency and accuracy of wood classification and stacking. At the same time, the overall structural layout is reasonable, providing a stable foundation for the subsequent functional realization of each component, and helping to improve the orderliness of wood management in the entire furniture processing process.

[0034] Furthermore, the first slider 7 has a first threaded groove 17, and the first screw 5 is threaded in the first threaded groove 17; the second slider 15 has a second threaded groove 18, and the second screw 11 is threaded in the second threaded groove 18; the third slider 16 has a third threaded groove 19, and the third screw 12 is threaded in the third threaded groove 19.

[0035] In this embodiment, the screw's rotational motion can be precisely converted into the slider's linear motion, resulting in smooth and accurate transmission, as well as the ability to withstand large loads.

[0036] Furthermore, the stacking assembly includes a telescopic stacking rod 20 and a telescopic screw 21. The telescopic stacking rod 20 has a telescopic threaded groove 22. The second slider 15 and the third slider 16 are each provided with a fixed stacking rod 23. The fixed stacking rod 23 has a telescopic groove 24. Two limiting members are provided in the telescopic groove 24. The telescopic stacking rod 20 is slidably connected to the fixed stacking rod 23 and is located in the telescopic groove 24. The telescopic stacking rod 20 is inserted into the corresponding lifting sleeve 8. The telescopic screw 21 is rotatably connected to the fixed stacking rod 23 through a bearing and is located in the fixed stacking rod 23. The telescopic screw 21 is threaded in the telescopic threaded groove 22 and is driven by a telescopic control motor.

[0037] In this embodiment, this structure allows the stacking assembly to be flexibly adjusted according to the actual length of the wood, greatly improving the applicability of the device and meeting the stacking needs of wood of different lengths. At the same time, the telescopic screw 21 is driven by a telescopic control motor, which is convenient to operate and precise to control. It can quickly and accurately adjust the position of the telescopic stacking rod 20. When stacking heavy wood, this adjustable and stable structure can effectively distribute the weight of the wood, reduce excessive local stress, and reduce the risk of bending or breaking of the wood.

[0038] Furthermore, the limiting member is a limiting strip 25, and both sides of the telescopic stacking rod 20 have limiting grooves 26, and the limiting strip 25 is slidably disposed in the limiting grooves 26.

[0039] In this embodiment, the limiting structure can effectively restrict the movement direction of the telescopic stacking rod 20 within the telescopic groove 24 of the fixed stacking rod 23, preventing the telescopic stacking rod 20 from shifting or shaking during the telescopic process.

[0040] Furthermore, each of the telescopic stacking rods 20 is provided with a calibration infrared transmitter 27 at one end, and each of the lifting sleeves 8 is provided with a calibration infrared receiver 28, and the calibration infrared transmitter 27 and the calibration infrared receiver 28 are adapted to each other.

[0041] In this embodiment, the precise correspondence between the calibration infrared transmitter 27 and the calibration infrared receiver 28 enables a quick and accurate determination of whether the corresponding telescopic stacking rod 20 and the corresponding lifting sleeve 8 can be inserted. This design greatly improves the docking accuracy between the stacking components and the lifting sleeve 8, ensuring the accuracy and stability of the entire stacking structure.

[0042] Furthermore, the support mechanism includes multiple roller seats 29, multiple roller groove seats 30, and a connecting plate 31. Each roller seat 29 has a roller body 32 rotatably disposed below it and located on the corresponding roller groove seat 30. Each roller groove seat 30 has multiple support bases 33 disposed below it. The multiple roller seats 29 are respectively fixedly connected to the movable seat 2 and located below the movable seat 2. Each roller body 32 abuts against the corresponding roller groove seat 30. The multiple roller groove seats 30 are respectively fixedly connected to the connecting plate 31 and located on the connecting plate 31, and are arranged in a straight line. The multiple roller groove seats 30 are also disposed at the inner bottom of the protective cover 1.

[0043] In this embodiment, the roller body 32 rotates on the roller groove seat 30, which enables the movable seat 2 to slide flexibly within the protective cover 1, making it convenient to place the stacked wood inside the protective cover 1.

[0044] Furthermore, the furniture processing wood sorting and stacking device also includes a closing mechanism, an anti-deviation component, and two locking components. The front end face of the protective cover 1 has an opening 34. The closing mechanism is located on the outside of the movable seat 2 and also abuts against the opening 34. The anti-deviation component is located on one end face of the closing mechanism. Both locking components are located on the outermost roller groove seat 30, and one of the locking components is inserted into one side of the closing mechanism.

[0045] In this embodiment, the sealing mechanism can seal the interior when the device is not in use or during stacking to prevent dust, debris, etc. from entering and protect the internal structure and wood. The anti-deviation component is provided on one end face of the sealing mechanism to prevent the sealing door 37 from shifting during use. The two locking components can lock the sealing door 37 to further enhance the stability of the seal.

[0046] Furthermore, the closing mechanism includes multiple central connecting rods 35, multiple bottom connecting rods 36, and a closing door 37. One end face of the closing door 37 is provided with two handles 38. The closing door 37 is fixedly connected to the movable seat 2 through the central connecting rods 35 and the bottom connecting rods 36, and is located on the outside of the movable seat 2. The closing door 37 also abuts against the opening 34.

[0047] In this embodiment, the closed door 37 is fixedly connected to the movable seat 2 by the middle connecting rod 35 and the bottom connecting rod 36, so that the closed door 37 can accurately abut against the opening 34 of the protective cover 1 to achieve a good sealing effect. The handle 38 is designed to facilitate the operator to open and close the closed door 37.

[0048] Furthermore, the anti-deviation component includes multiple weight blocks 39 and a mounting base 40. The multiple weight blocks 39 are all inserted into the mounting base 40. The mounting base 40 is located on one end face of the closed door 37 and is also located below the two handles 38.

[0049] In this embodiment, the weight of one end of the closed door 37 is increased by the design of the load-bearing block 39. The gravity makes the closed door 37 more stable against the opening 34 of the protective cover 1 after it is closed, effectively preventing the closed door 37 from shifting due to vibration or other external forces during the operation of the device.

[0050] Furthermore, the locking assembly includes a locking rod 41, an electric push rod 42, and an L-shaped seat 43. The locking rod 41 is disposed at the output end of the electric push rod 42, the electric push rod 42 is disposed on the L-shaped seat 43, the L-shaped seat 43 is disposed on the roller groove seat 30, and the locking rod 41 is inserted into one side of the closed door 37.

[0051] In this embodiment, when the closed door 37 needs to be locked, the electric push rod 42 pushes the locking rod 41 to insert into the corresponding position on one side of the closed door 37, thereby firmly locking the closed door 37. When the closed door 37 moves to the end of the roller groove seat 30 away from the protective cover 1, another locking component can be locked, making it convenient for workers to stack wood on multiple stacking components. When the closed door 37 needs to be opened, the electric push rod 42 retracts the locking rod 41. This locking component is easy to operate and precise to control, ensuring that the closed door 37 is reliably locked when needed. When stacking heavy wood, it provides additional fixing protection for the closed door 37, preventing the closed door 37 from being opened accidentally, further enhancing the overall stability and safety of the device, and ensuring the normal operation of the wood placement part and the stacking structure.

[0052] In this invention, the device is placed in a suitable work area to ensure that the multiple support bases 33 in the support mechanism are stably in contact with the ground, providing stable support for the entire device. Simultaneously, the multiple roller seats 29 are connected to the movable seat 2, and the roller bodies 32 can rotate flexibly on the roller groove seats 30, facilitating the subsequent sliding operation of the movable seat 2 within the protective cover 1. Then, according to the required specifications of the stacked wood, the second dual-axis motor 9 and the third dual-axis motor 10 are started, and the second screw 11 and the third screw 12 rotate under the drive of their respective motors. The two second sliders 15 are acted upon by the second threaded groove 18, and the two third sliders 16 are acted upon by the third threaded groove 19, thereby adjusting the position of the stacking components to adapt the device to the stacking requirements of different specifications of wood. At this time, the two stacking components at the higher position are the first type of stacking area, and the two stacking components at the lower position are the second type of stacking area. Then, the first dual-axis motor 4 is started, and the two first screws 5 drive the first sliders 7 to move, causing the two lifting sleeves 8 to move towards or away from each other. When the calibration infrared light... When the transmitter 27 and the calibration infrared receiver 28 are aligned, the first dual-axis motor 4 stops. This operation ensures that the telescopic stacking rod 20 can be accurately inserted into the corresponding supporting sleeve 8. This adjustment can be determined according to the position of the corresponding stacking component. Then, according to the length of the wood, the telescopic control motor is started, driving the telescopic screw 21 to rotate in the telescopic threaded groove 22 of the telescopic stacking rod 20, causing the telescopic stacking rod 20 to slide in the telescopic groove 24 of the fixed stacking rod 23, thereby realizing the extension and retraction of the telescopic stacking rod 20 to match the length of the wood. Then, the timber is placed on the two horizontally arranged telescopic stacking rods 20. After sorting and stacking, the operator holds the two handles 38 on the closing door 37 of the closing mechanism to close the closing door 37, so that it is held against the opening 34 of the protective cover 1. At this time, the telescopic stacking rod 20 can be accurately inserted into the corresponding lifting sleeve 8, thereby ensuring stable support for the stacked timber. Then, the electric push rod 42 in the locking assembly is activated to push the locking rod 41 into one side of the closing door 37, and the closing door 37 is firmly locked to prevent accidental opening.

[0053] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
