Technical Field
[0001] This utility model relates to the field of fully automatic bamboo laminated timber assembly system, and in particular to an automatic feeding device applied to the fully automatic bamboo laminated timber assembly system. Background Technology
[0002] Bamboo laminated timber is a new type of substrate made by processing bamboo into rectangular strips of a certain size, then treating them for corrosion, mildew, and insect resistance, drying, applying adhesive, and finally gluing them together. It retains the excellent physical and mechanical properties of bamboo and has the advantages of a low coefficient of water absorption and expansion, resistance to cracking and deformation. It has wide applications and is one of the main directions for the future development of the bamboo industry.
[0003] Currently, in the production process of bamboo laminated timber, bamboo strip assembly (i.e., strip selection and sorting) is a difficult problem to solve in the automation of bamboo processing. Existing strip sorting machines can only select a portion of the bamboo strips, but the bamboo strip assembly work still needs to be done manually. Currently, assembly workers generally... Visual The bamboo strip assembly process is generally carried out through inspection, following the principle that defective bamboo strips (i.e., strips with differences such as internal carbonization, mold, black knots, etc.) are arranged on the outside, while undefective bamboo strips (i.e., qualified strips) are arranged on the inside. Severely defective strips, such as those with cracks or missing edges, are discarded during manual assembly. While existing manual bamboo strip assembly can achieve the task, it requires manual loading; workers need to place a pile of bamboo strips to be selected and arranged on a frame (such as a sorting rack) for assembly, resulting in low automation and efficiency. Utility Model Content
[0004] This utility model provides an automatic feeding device for a fully automatic bamboo laminated timber assembly system, which overcomes the problems of existing technologies that require manual feeding (i.e., manual handling) and have low automation and efficiency.
[0005] To achieve the objective, the technical solution provided by this utility model is as follows: An automatic feeding device for a fully automated bamboo laminated timber assembly system includes a feeding rack for receiving bamboo strips that have undergone surface defect detection on an inspection table and then being transferred to it one by one, and a bamboo strip pushing device for pushing the bamboo strips on the feeding rack to a bamboo strip storage device. The bamboo strip pushing device is provided with a receiving groove for receiving bamboo strips on the inspection table and a pushing component for pushing bamboo strips in the receiving groove to the bamboo strip storage device. The feeding rack includes a rectangular support located between the bamboo strip storage device and the inspection table, and a bamboo strip pushing device fixedly mounted on the table surface of the rectangular support. The bamboo strip pushing device includes multiple vertical frames arranged sequentially along the length of the table surface of the rectangular support. Each vertical frame has a notch horizontally opposite to the groove of a limiting groove and upper and lower guide plates installed on the notch, forming the receiving groove between the upper and lower guide plates. The bamboo strip pushing device also includes the pushing component for pushing bamboo strips in the receiving groove to the bamboo strip storage device.
[0006] Furthermore, the upper guide plate is connected to the top of the notch in an adjustable manner via an L-shaped plate. The bottom edge of the L-shaped plate is fixed to the back of the upper guide plate, and its side edge is used to fix the upper guide plate to the top of the notch in an adjustable manner via fasteners. The distance between the upper and lower guide plates can be adjusted by adjusting the height of the upper guide plate.
[0007] Furthermore, the front sections of both the upper and lower guide plates are provided with outwardly inclined front sections, and a flared opening is formed between the two front sections.
[0008] Furthermore, there are multiple pusher assemblies, and these multiple pusher assemblies are arranged sequentially and at intervals along the length of the rectangular support on multiple vertical frames.
[0009] Furthermore, each pusher assembly includes a strip track mounted on the side wall of the vertical frame, a stroke cylinder, and a movable base that slides on the strip track. The back of the movable base is mounted on the strip track via a slider. The bottom end of the stroke cylinder is connected to the side wall of the vertical frame, and its piston rod is connected to the back of the movable base. The front of the movable base is provided with a pusher plate that pushes the bamboo strips in the receiving groove laterally into the limiting groove. The pusher plate drives the movable base to reciprocate on the strip track through the piston rod of the stroke cylinder, thereby completing the bamboo strip pushing operation one by one.
[0010] Furthermore, the pusher plate is Z-shaped, with the front section being the pusher head, the middle section being the crossbar, and the rear end being the connecting part. The connecting part is movably connected to the front of the movable base via a connector. The front of the movable base is also provided with a pulling cylinder, the piston rod of which is connected to the connecting part. The pusher plate pulls the connecting part via the piston rod of the pulling cylinder, causing the pusher head to tilt upwards.
[0011] Compared with existing technologies, the technical solution provided by this utility model has the following advantages: The automatic feeding device has an ideal structural design, employing a feeding rack and bamboo strip pushing device that work in conjunction with the inspection table. This allows bamboo strips to pass one by one from the inspection table into the receiving groove on the bamboo strip pushing device. Then, the pushing assembly smoothly pushes the bamboo strips from the receiving groove into the limiting groove on the bamboo strip retention device, thus completing the automatic feeding operation. This enables highly efficient automatic feeding of bamboo strips, saving labor costs and significantly improving production efficiency. Attached Figure Description

[0026] To further understand the content of this utility model, the following embodiments are described in detail. The embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0027] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 9 The fully automated bamboo laminated timber assembly system includes an automatic feeding device 1 for feeding bamboo strips after surface defect detection, a bamboo strip holding device 2 for receiving bamboo strips from the automatic feeding device 1 and moving them forward, a sorting and collecting device 4 located above the bamboo strip holding device 2 for grabbing and stacking the bamboo strips from the holding device 2 to form bamboo strip blanks 3 to be bundled, and an automatic unloading device 5 for dragging, bundling, and transferring the bamboo strip blanks from the sorting and collecting device. This fully automated bamboo laminated timber assembly system offers an ideal assembly method and excellent results, significantly improving the quality of bamboo laminated timber. The system boasts a high degree of automation, featuring automatic feeding, horizontal bamboo strip storage, sorting and collecting, and automatic unloading functions, forming a continuous operation mode and greatly reducing labor costs.
[0028] See attached document Figure 2 , Figure 3 , Figure 5 and Figure 7The automatic feeding device 1 includes a feeding rack 11 for receiving bamboo strips that have been inspected for surface defects by the inspection table 10 and then transferred to it one by one, and a bamboo strip pushing device 12 for pushing the bamboo strips on the feeding rack 11 to the bamboo strip storage device 2. The bamboo strip pushing device 12 is provided with a receiving groove 120 for receiving bamboo strips on the inspection table 10 and a pushing assembly for pushing the bamboo strips in the receiving groove 120 onto the bamboo strip storage device 2. The feeding rack 11 includes a rectangular support located between the bamboo strip storage device 2 and the inspection table 10 and a table fixedly mounted on the rectangular support. A bamboo strip pushing device includes multiple vertical frames 111 arranged sequentially along the length of a rectangular support platform. Each vertical frame 111 has a notch horizontally opposite to the groove of a limiting groove 200, and upper and lower guide plates 112 and 113 installed on the notch. A receiving groove 120 is formed between the upper and lower guide plates 112 and 113. The top of the receiving groove 120 is provided with a baffle plate to prevent bamboo strips from passing through. The bamboo strip pushing device 12 also includes a pushing assembly that pushes the bamboo strips in the receiving groove 120 onto the bamboo strip holding device 2. The front sections of the upper and lower guide plates 112 and 113 are each provided with outwardly inclined front sections, and a flared opening is formed between the two front sections. The flared opening design aims to avoid feeding difficulties caused by the bending of the bamboo strips, thereby reducing the failure rate of the equipment. The detection table 10 is an existing structure of a patent previously filed in the Chinese Patent Database entitled "A Bamboo Strip Defect Detection Table" (Patent No.: ZL 202421534837.X, Authorization Publication Date: 2025.04.25). This detection table 10 has a high degree of intelligence in detecting bamboo strip defects, providing comprehensive and precise detection. It can detect information on each bamboo strip for various defects such as dents, missing edges, cracks, and wormholes. The information is processed by an industrial control computer, and a mechanical gripper selectively picks up bamboo strips from the limiting grooves on the rotating belt and places them onto a sorting rack for stacking and assembling into bamboo strip blanks (e.g., 25 bamboo strips per group). Alternatively, the number of bamboo strips in the bamboo strip blanks can be preset to other numbers. The gripper of the mechanical head follows these principles: defective bamboo strips (i.e., strips with differences such as internal carbon, mold, black knots, etc.) are sorted out on the outside, while undefective bamboo strips (i.e., qualified strips) are sorted out on the inside, and bamboo strips with serious defects such as cracks or missing edges are not gripped.
[0029] See attached document Figure 5 and Figure 7The upper guide plate 112 is vertically adjustable to the top of the notch via an L-shaped plate 114. The bottom edge of the L-shaped plate 114 is fixed to the back of the upper guide plate 112, and its side is vertically adjustable to fix the upper guide plate 112 to the top of the notch via fasteners 115. The distance between the upper and lower guide plates 112 and 113 can be adjusted by adjusting the height of the upper guide plate 112. Multiple push bar assemblies are arranged sequentially and at intervals along the length of the rectangular bracket on multiple vertical frames 111.
[0030] See attached document Figure 1 , Figure 4 , Figure 5 and Figure 7 Each pusher assembly includes a strip track 13 mounted on the side wall of the vertical frame 111, a stroke cylinder 14, and a movable base 15 that slides on the strip track 13. The back of the movable base 15 is mounted on the strip track 13 via a slider. The bottom end of the stroke cylinder 14 is connected to the side wall of the vertical frame 111, and its piston rod is connected to the back of the movable base 15. The front of the movable base 15 is provided with a pusher plate 16 that pushes the bamboo strips in the receiving groove 120 laterally into the limiting groove 200. The pusher plate 16 drives the movable base 15 to reciprocate on the strip track 13 through the piston rod of the stroke cylinder 14, thereby completing the bamboo strip pushing operation one by one. The pusher plate 16 is Z-shaped. Its front section is the pusher head, its middle section is the crossbar, and its rear end is the connecting part. This connecting part is movably connected to the front of the movable base 15 via a connector (such as a bolt). The front of the movable base 15 is also equipped with a pulling cylinder 17. The piston rod of the pulling cylinder 17 is connected to the connecting part. The pusher plate 16, through the piston rod of the pulling cylinder 17, pulls the connecting part, causing the pusher head to tilt upwards. This prevents the pusher head from obstructing the rapid entry of the next bamboo strip into the receiving groove. Since the entire equipment operates continuously, especially when bamboo strips are inspected one by one through the inspection table 10, the speed is relatively fast. To ensure uninterrupted feeding of the previous and next bamboo strips, after the previous bamboo strip is pushed, the piston rod of the pulling cylinder 17 pulls the connecting part, causing the pusher head to tilt upwards. This prevents the pusher plate 16 from failing to return to its original position in time, thus avoiding the problem of the next bamboo strip being obstructed from entering quickly.
[0031] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 8The bamboo strip retention device 2 includes a retention rack 21 and a retention rotating belt 20 mounted on the retention rack 21 and driving the bamboo strips forward. The retention rotating belt 20 has multiple limiting grooves 200 arranged sequentially along its length. The groove of one limiting groove 200 at the beginning of the retention rotating belt 20 is horizontally aligned with the receiving groove 120. The feeding rack 11 pushes the bamboo strips from the receiving groove into the multiple limiting grooves 200 one by one through a pushing assembly. The retention rotating belt 20 drives the bamboo strips in each limiting groove 200 to move forward in conjunction with the sorting and collecting process. The device 4 is used in conjunction with the storage rotating belt 20, which includes a drive shaft and a driven shaft mounted on the storage rack 21, and left and right transmission chains 22 and 23 wound between the drive shaft and the driven shaft; it also includes a plurality of carrier chain plates 24 arranged in close proximity between the left and right transmission chains 22 and 23 to form a conveying platform. Each carrier chain plate 24 has a plurality of strip limiting blocks 25 spaced apart along its length. Each strip limiting block 25 has a U-shaped groove, and the U-shaped grooves of the plurality of strip limiting blocks 25 are combined to form the limiting groove 200 for placing a single bamboo strip. Each carrier chain plate 24 has three strip limiting blocks 25 spaced apart along its length, and the three strip limiting blocks 25 are respectively located at the left end, middle and right end of each carrier chain plate 24.

The robotic arm 41 selectively picks up bamboo strips from the limiting groove 200 on the retaining rotating belt 20 and places them onto the sorting and collecting rack 42 for stacking and arranging into bamboo strip blanks 3 to be bundled, based on the detection results of the bamboo strips surface defects by the detection table 10 (such as the strip collection order output after processing by an artificial intelligence-based industrial control computer, following the principle that defective bamboo strips (i.e., strips with differences such as internal carbon, mold, black knots, etc.) are sorted on the outside, and undefective bamboo strips (i.e., qualified strips) are sorted on the inside, and bamboo strips with serious defects such as cracks, missing edges, etc.). The number of horizontal rail rods 411 is two, and the two horizontal rail rods 411 are arranged alternately on the crossbeam of the portal frame 410, and each horizontal rail rod 411 is connected to a mechanical head that can move laterally on it.
[0033] See attached document Figure 6 , Figure 9 and Figure 10The sorting and receiving rack 42 includes receiving supports 421 located on both sides of the storage rotating belt 20 and a sorting and receiving platform 422 mounted on the receiving supports 421 and movable left and right above the storage rotating belt 20. The sorting and receiving platform 422 is provided with a sorting and receiving groove 423 for receiving bamboo strips from the robotic arm 41. The sorting and receiving groove 423 is provided with a strip-shaped opening 424 for stacking multiple bamboo strips into a blank, and a groove 424 mounted on the sorting and receiving groove 423 for... A clamping assembly for laterally pressing stacked bamboo strips on the slot 424 includes a horizontal track 425 located on one side of the slot 424, a slider slidably mounted on the horizontal track 425, an L-shaped stop 426 fixed on the front of the slider, and a clamping cylinder 427 for driving the L-shaped stop 426 to slide on the horizontal track 425.

This pusher assembly includes a pusher track 54 arranged along the width of the unloading rack 52's table surface and a pusher plate 55 slidably mounted on the pusher track 54. The pusher plate 55 is driven by a power source (such as a cylinder) to move along the pusher track 54 and push the bundled bamboo strip blanks 3 onto the discharge rack 53, i.e., onto the discharge rack 53. The bamboo strip blanks then fall down the discharge rack 53's sliding portion 530 onto the receiving trolley. There are two pusher assemblies, located on opposite sides of the unloading rack 52's table surface.

The left and right claw blocks 506 and 507 open or close by pulling the first linkage rod 61 repeatedly by the pulling cylinder 64, that is, clamping the side of the bamboo strip blank 3 to be bundled.
[0038] See attached document Figures 1-14 The method of using the fully automatic bamboo laminated timber assembly system includes the following steps: 1) Automatic feeding: bamboo strips are inserted one by one from the inspection table, and after the surface defects of the bamboo strips are detected by the inspection table 10, they enter the receiving groove 120 on the bamboo strip flat pushing device 12.
[0039] 2) Bamboo strip retention: The bamboo strip in the receiving groove 120 is pushed into the limiting groove 200 on the bamboo strip retention device 2 by the pusher assembly and the bamboo strip is driven forward by the retention rotating belt 20.
[0040] 3) Sorting and collecting: The robotic arm 41, based on the inspection table 10's detection of surface defects in the bamboo strips (i.e., information collection on the surface of each bamboo strip), and after processing by an artificial intelligence-based industrial control computer algorithm, outputs the collecting order. The principle of the collecting order is to sort defective bamboo strips (i.e., strips with differences such as internal carbon, mold, black knots, etc.) to the outside, and undefective bamboo strips (i.e., qualified strips) to the inside, and not to grab bamboo strips with serious defects such as cracks, missing edges, etc. The robotic arm selectively grabs the bamboo strips in the limiting groove 200 on the retaining rotating belt 20 and places them onto the sorting and collecting rack 42 for stacking and sorting to form bamboo strip blanks 3 to be bundled (e.g., 25 bamboo strips form a group).
[0041] 4) Automatic feeding: The bamboo strip blank 3 is dragged by the dragging claw 500 to the bamboo strip bundling machine 51 to complete the bamboo strip bundling operation. Then it is dragged to the unloading rack 52 for discharge. The push plate 55 pushes the bundled bamboo strip blank 3 on the table of the unloading rack 52, that is, pushes the bamboo strip blank 3 onto the discharge rack 53, and then falls down the sliding part 530 of the discharge rack 53 onto the receiving trolley.

However, the description is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
