Description

Technical Field

[0001] This invention relates to the field of timber processing technology, specifically to an automatic feeding process for individual recycled timber strips to be incorporated into timber squares. Background Technology

[0002] In the production of recycled wood or engineered wood products, it is usually necessary to collect and sort the recycled or cut single slender wood strips and assemble them into rows of wood blocks of a certain size to facilitate subsequent gluing, hot pressing or splicing processes.

[0003] Most existing timber feeding processes use a conveyor belt combined with a blocking mechanism. The conveyor belt continuously transports individual timber strips to the end, and the timber strips are intercepted by a rising baffle, causing them to accumulate in front of the baffle. However, relying solely on the baffle can only restrict the longitudinal movement of the timber, and cannot effectively control the lateral position and neatness of the accumulated timber. Due to vibration during the conveying process or the differences in the shape of the timber strips themselves, the accumulated timber bundles are prone to unevenness or loose arrangement. If they are directly discharged into the next process, it is very easy to cause misalignment in subsequent processing, affecting the quality of the finished product.

[0004] To address the issues of centering and alignment, some existing equipment adds independent lateral clamping or positioning cylinders to the conveyor line. While this achieves positioning, it results in extremely complex control logic for the overall equipment. During production, additional sensors are required to detect whether the timber is in place, and the sequence of actions of the blocking cylinder and the lateral positioning cylinder must be precisely coordinated. This intermittent action, relying on an independent power source and electrical control, not only increases the manufacturing cost and maintenance difficulty of the equipment, but also makes it easy for the positioning and feeding actions to become asynchronous if the sensor sensitivity decreases or the air circuit response is delayed. This can cause the timber to jam or be mistakenly discharged before it is fully aligned, thereby reducing the stability and production efficiency of automatic feeding. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic feeding process for individual recycled timber strips to form timber squares, which solves the problem in existing technologies where the positioning and feeding actions are often out of sync, leading to timber jamming or accidental discharge when not fully aligned.

[0006] To achieve the above objectives, this invention provides an automatic feeding process for single-strip recycled timber into timber squares. This process employs an automatic feeding device, which mainly includes a machine base, a support assembly, a feeding assembly, a feeding block assembly, and a positioning assembly mounted on the machine base. The core of this process lies in utilizing mechanical linkage to achieve automatic convergence and positioning of the timber squares, specifically through the following methods: First, the feeding component drives a single piece of timber to move in one direction, and the material blocking component on the right side of the machine physically blocks the timber, so that multiple groups of single pieces of timber that are subsequently transported are blocked on the feeding component and gradually converge into a row.

[0007] The key innovation of this invention lies in the establishment of a mechanical linkage mechanism between the material feeding action and the positioning action. During the process of the material feeding component releasing the obstruction or moving, the power source of the material feeding component directly drives the positioning component to move synchronously. During its movement, the positioning component actively squeezes the transmission mechanism on the support component, driving the actuator inside the support component to move towards the center line of the machine. Thus, at the moment when the timber is about to be discharged, the squeezing action from both sides towards the center forces the converged timber to be centered and positioned. Subsequently, the timber continues to be discharged through the feeding component. This design eliminates the dependence on an independent positioning power source and complex timing control.

[0008] In one specific embodiment, the actuator of the support component adopts a structure combining lever transmission and elastic reset. A positioning plate is slidably connected inside the support base. The positioning plate is connected to the reset spring through an outer support sleeve. When subjected to an external driving force, the positioning plate overcomes the spring force and moves inward to clamp the wooden block. When the driving force disappears, the reset spring drives the positioning plate to automatically reverse and reset, making room for the next convergence.

[0009] To convert the vertical movement of the timber assembly into the horizontal clamping movement of the positioning plate, this invention designs a specific cam lever mechanism. A lever is rotatably connected to the machine base, with a cam connected to one end of the lever and the other end used to push the positioning plate. A slide plate is attached to the baffle of the timber assembly, and a boss is provided on the slide plate. When the baffle moves up and down, it drives the boss to squeeze the cam, forcing the cam to rotate, which in turn drives the lever to swing. The swing end of the lever pushes the positioning plate to slide inward through the cooperation of the protrusion and the slide groove. Preferably, the length of the lever's power arm is designed to be greater than the length of the resistance arm, using the lever principle to amplify the driving force and ensure that the positioning plate can effectively clamp the entire row of timber.

[0010] Furthermore, considering the differences in timber specifications and equipment protection, this invention integrates an overload protection mechanism in the transmission chain. The positioning plate and the transmission sleeve driven by the lever are not rigidly connected, but elastically connected by a compression spring. When the timber stacks are too wide, causing the positioning plate to be obstructed and unable to move further inward, the stroke of the lever is absorbed by the compression spring, preventing mechanical parts from being damaged by hard collisions.

[0011] Furthermore, to accommodate timber of different widths and adjust the positioning force, this invention also provides an adjustment mechanism based on inclined plane transmission. The positioning component includes an adjusting screw and a slide bar. The slide bar and the slide plate are connected by an inclined connecting part and a T-shaped transmission block. The operator rotates the adjusting screw to move the slide bar in the vertical direction. Utilizing the inclined plane guiding principle, the vertical displacement is converted into the horizontal displacement of the slide plate. This adjustment changes the relative distance between the boss on the slide plate and the cam, thereby adjusting the degree of compression of the cam and the swing amplitude of the lever, achieving fine adjustment of the positioning stroke without replacing parts.

[0012] In summary, this invention, through ingenious mechanical structure design, achieves fully automated linkage of blocking, converging, positioning and discharge during the feeding process. It not only ensures the neatness and accuracy of timber feeding, but also features a compact structure, convenient adjustment and stable operation.

[0013] This invention provides an automated feeding process for individual recycled timber strips to be fed into timber squares. It offers the following advantages: 1. This invention utilizes a mechanical linkage structure between the baffle and the positioning component. By leveraging the upward movement of the material feeding component to release the obstruction, it directly drives the lever and positioning plate to laterally compress and position the timber. This design eliminates the complex control logic of existing technologies that rely on independent cylinders and sensors, achieving purely mechanical synchronization of lifting and positioning. This not only significantly reduces the manufacturing cost and electrical maintenance difficulty of the equipment but also completely solves the positioning failure problem caused by sensor delay or asynchronous pneumatic response, ensuring absolute accuracy of the action timing and high reliability of the feeding process.

[0014] 2. This invention utilizes the continuous conveying of the feeding assembly and the centering clamping of the positioning plates on both sides to effectively solve the problem of lateral scattering that easily occurs when timber is gathered. At the moment the baffle is lifted to release the material, the positioning plates on both sides are driven by the cam mechanism to move towards the center line, forcibly correcting the posture of the timber on the conveyor belt, so that loose individual timbers are arranged into a compact, centered row before discharge. This effect directly eliminates the hidden danger of uneven timber arrangement affecting the quality of subsequent gluing or hot-pressing processes in the prior art, significantly improving the yield of recycled timber production.

[0015] 3. An adjustment mechanism based on the inclined plane transmission principle is incorporated, allowing the contact depth between the slide and the cam to be changed by rotating the adjusting screw. Operators do not need to replace any parts; simple adjustments are all that is required to change the lever's swing amplitude and the positioning plate's compression degree. This feature enables the device to flexibly adapt to the production needs of timber of different widths, and also facilitates fine-tuning and compensation after mechanical wear occurs over long-term use, effectively extending the equipment's service life and expanding its applicability.

[0018] The technical solutions in 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.

[0019] Please see the appendix Figure 1 - Appendix Figure 6This invention provides an automatic feeding process for single recycled timber strips to be fed into timber squares, including a machine base 1. The machine base 1 provides support for the overall device, ensuring stable operation. A support component 2 is provided on the upper surface of the machine base 1, providing a space for the timber to be fed in. A feeding component 3 is provided on the upper surface of the support component 2, which drives a single timber strip to move unidirectionally to allow multiple timber squares to converge. It can also drive the converged timber squares to move unidirectionally to achieve feeding. A blocking component 4 is provided on the upper right side of the machine base 1, which blocks the timber. By blocking the timber, the movement of the timber can be restricted, thus enabling the timber to converge. A positioning component 5 is provided on the outer wall of the blocking component 4, which positions the converged timber to ensure that it remains in a specific position when moving to the next process.

[0020] Reference Figure 2 and Figure 6 The support assembly 2 includes two symmetrically arranged support seats 21, which are respectively located on the upper surface of the machine base 1 near the front and rear ends. The two sets of support seats 21 are connected to each other by a support plate 22. The support seats 21 and the support plate 22 are integrally molded and have high strength during use. A through groove is provided at the end of the support seat 21 near the center line of the machine base 1. A positioning plate 23 is slidably connected inside the through groove. When the positioning plate 23 moves towards the center line of the machine base 1, it can push the gathered wood to move towards the center line of the machine base 1, so that the wood can be discharged from a specific position. At the same time, multiple sets of wood can be kept close together in the front and rear direction, which facilitates subsequent operations. An outer support sleeve 212 is fixedly connected to the outer wall of the positioning plate 23. The outer support sleeve 212 and the support seat 21 are elastically connected by a return spring 213. When the positioning plate 23 is pressed, it will move towards the center line of the machine base 1. When the pressure is removed, the return spring 213 can drive the positioning plate 23 to move in the opposite direction and reset.

[0021] Reference Figure 2 and Figure 6A transmission sleeve 24 is slidably connected to the side of the positioning plate 23 away from the center line of the machine tool 1. The transmission sleeve 24 and the positioning plate 23 are elastically connected by a compression spring 210. When the transmission sleeve 24 moves, it will drive the positioning plate 23 to move by compressing or pulling the compression spring 210. A limit block 211 is provided on the inner wall of the positioning plate 23. The limit block 211 can limit the movement range of the transmission sleeve 24 and prevent the compression spring 210 from being damaged due to excessive movement of the transmission sleeve 24. A lever 25 is rotatably connected to the upper surface of the machine tool 1. With the connection point between the lever 25 and the machine tool 1 as the boundary, the left side of the lever 25 is the resistance arm of the lever 25. The right side of lever 25 is the power arm of lever 25. The length of the power arm of lever 25 is greater than the length of the resistance arm. This design makes it easier to rotate lever 25 during use. A protrusion 28 is fixedly connected to the outer wall of the left end of the resistance arm of lever 25. The inner wall of the transmission sleeve 24 is provided with a groove 29 for accommodating the protrusion 28. When lever 25 rotates, it will drive the transmission sleeve 24 to move by pressing the groove 29 through the protrusion 28 on the outer wall of the resistance arm. A vertical rod 26 is fixedly connected to the outer wall of the right end of the power arm of lever 25. A cam 27 is fixedly connected to the outer wall of the vertical rod 26. By pressing the cam 27, lever 25 can be rotated.

[0022] Reference Figure 1 - Figure 3 The feeding assembly 3 includes two sets of symmetrically arranged rotating shafts 32. The two sets of rotating shafts 32 are respectively located on the upper surface of the machine base 1 near the left and right ends. The two sets of rotating shafts 32 are connected by a conveyor belt 33. A support plate 22 passes through the inner wall of the conveyor belt 33 from the center position. The support plate 22 can support the conveyor belt 33 and prevent the wood from crushing it. A drive motor 31 is installed on the upper surface of the machine base 1. The drive motor 31 is connected to one of the rotating shafts 32 by a reducer. By starting the drive motor 31, the rotating shaft 32 can be driven to rotate, thereby driving the wood-to-material blocking assembly 4 placed above the conveyor belt 33 to move.

[0023] Reference Figure 2 - Figure 4 The material blocking component 4 includes a support frame 41, which is designed in an n-shape to prevent the timber from moving during use. A second support plate 42 is fixedly connected to the upper end of the support frame 41. A cylinder 43 is installed at the end of the second support plate 42 away from the support frame 41. A baffle 44 is installed at the lower end of the output shaft of the cylinder 43. By starting the cylinder 43, the baffle 44 can be moved up or down. When the baffle 44 moves to the lowest point, the timber will not be able to move to the right through the baffle 44. Thus, the timber will gather on the left side of the baffle 44, waiting for the operator to continue putting timber in. After enough timber is put in, multiple groups of timber will converge above the conveyor belt 33 and keep their right ends aligned. When the baffle 44 moves upward, multiple groups of timber will be released at the same time, thus realizing single timber entry and whole row exit.

[0024] Reference Figure 3 - Figure 5 The positioning component 5 includes a horizontal plate 51, which is fixedly connected to the outer wall of the baffle 44 and moves synchronously with the up and down movement of the baffle 44. An adjusting screw 55 is threaded through and connected to the upper surface of the horizontal plate 51. A slide bar 56 is rotatably connected to the lower surface of the adjusting screw 55. Rotating the adjusting screw 55 moves the horizontal plate up and down. A sliding plate 52 is slidably connected to the outer wall of the baffle 44. The sliding plate 52 can slide horizontally back and forth on the outer wall of the baffle 44. A boss 53 is provided at the end of the sliding plate 52 away from the center line of the baffle 44. When the baffle 44 moves up and down, it drives the sliding plate 52 to move synchronously. The boss 53 then presses against the cam 27, forcing it to rotate outwards. This causes the lever 25 to swing, thereby using the positioning plate 23 to press the wooden block towards the center position. A connecting part 54 is provided near one end of the slide bar 56. The end of the connecting part 54 near the slide bar 56 is in contact with the outer wall of the slide bar 56 and is set in an inclined shape. A transmission block 58 is fixedly connected to the outer wall of the slide bar 56. A transmission groove 59 is provided on the end face of the connecting part 54 that contacts the slide bar 56. The transmission block 58 slides on the inner wall of the transmission groove 59 and its cross-section is set in a T shape. In this way, when the slide bar 56 moves up and down, it can drive the slide plate 52 to move horizontally. Thus, the degree of pressure of the slide plate 52 on the cam 27 can be adjusted according to different usage environments. At the same time, during the up and down movement of the baffle 44, since the slide plate 52 does not press the cam 27 all the time, but only briefly presses the cam 27 in the middle, the positioning plate 23 will not be in constant contact with the wood, which can prevent the positioning plate 23 from affecting the normal movement of the wood.

[0025] Reference Figure 3 - Figure 5 A blocking member 57 is fixedly connected to the upper end of the slide plate 52. The blocking member 57 is L-shaped and extends over the baffle 44 from above and blocks the front surface of the baffle 44. In this way, it can restrict the end of the wooden block to prevent the end of the wooden block from spreading too much, and it can also restrict the movement of the slide plate 52 to prevent the operator from over-adjusting the slide bar 56, causing the slide plate 52 to get too close to the outside of the baffle 44. It can provide a reference for the adjustment of the overall device.

[0026] Working principle: When the whole device is working, firstly, the cylinder 43 drives the baffle 44 to descend to the blocking position, and at the same time the drive motor 31 starts, driving the conveyor belt 33 to continuously transport single timbers. The timbers move to the right under the push of the conveyor belt until they are blocked by the baffle 44. As subsequent timbers are continuously delivered, multiple single timbers automatically converge side by side on the left side of the baffle 44 and form a row of timbers with the right end aligned. During the convergence process, the operator can rotate the adjusting screw 55 to change the horizontal position of the slide plate 52 using the inclined plane transmission mechanism, thereby preset the clamping force of the subsequent positioning mechanism to adapt to timbers of different specifications.

[0027] Once the timber has been gathered, the linkage positioning and discharge stage begins. Cylinder 43 drives baffle 44 upward to prepare for material discharge. During the upward movement, the boss 53 on the slide plate 52 linked to baffle 44 briefly squeezes the cam 27 on lever 25, forcing lever 25 to swing. The swing of the lever pushes the positioning plates 23 on both sides toward the center line through transmission sleeve 24, quickly centering and compacting the entire row of timber. When baffle 44 is fully raised above the height of the timber, the boss 53 separates from the cam 27, and the return spring 213 then drives the positioning plate 23 to return to its original position, releasing the timber. At this time, the neatly arranged row of timber is smoothly discharged to the next process under the drive of conveyor belt 33. Subsequently, baffle 44 descends and returns to its original position, and the device enters the next cycle of operation.

[0028] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
