Description

Technical Field

[0001] This invention relates to the field of board manufacturing technology, specifically to an intelligent paving method for achieving continuous bamboo curtains stacked in a forward oblique pattern. Background Technology

[0002] Bamboo-wood composite plywood (including container flooring) utilizes a large amount of bamboo curtains. The installation of bamboo curtains generally falls into three categories: one is manual installation of narrow-width longitudinal or wide-width transverse curtains, where single layers of bamboo curtains are manually unrolled and spliced ​​in a staggered manner on a longitudinal production line; another is semi-mechanized installation of narrow-width longitudinal curtains, where the main production line stops after advancing one station, and the continuous bamboo curtains are mechanically unrolled on the longitudinal production line, advancing one station before stopping, with the second layer of bamboo curtains spliced ​​with the first; and the third is mechanized installation of wide-width transverse curtains, where the main production line does not stop, and the continuous bamboo curtains are rolled into a tube and unrolled in a vertical direction, with the speed of the continuous bamboo curtains matching the speed of the main production line. These installation methods have the following problems: First, they require many workers, with one worker needed for each layer of bamboo curtains, resulting in high labor intensity; second, the production line operates intermittently, and frequent starts and stops damage the equipment and reduce the accuracy of the board length direction; third, continuous unrolling and rotation production is currently only suitable for wide-width transverse curtains, and wide-width longitudinal curtains are also installed using intermittent telescopic synchronous installation. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a continuous bamboo curtain installation method that reduces manual labor intensity and improves work efficiency.

[0004] To achieve the above objectives, the present invention provides an intelligent paving method for continuous bamboo curtains with oblique stacking, which adopts the following technical solution: A smart paving method for achieving continuous bamboo curtains stacked diagonally in the forward direction includes the following steps: S1, Install the main mobile production line and the continuous bamboo curtain laying line. The direction of the main mobile production line is perpendicular to the direction of the continuous bamboo curtain laying line. The continuous bamboo curtain laying line lays the continuous bamboo curtain in the direction of the continuous bamboo curtain. The main mobile production line moves in a straight line and the continuous bamboo curtain laying line moves back and forth in a straight line. S2, the main moving production line is running, and the continuous bamboo curtain laying line is running at the same time. The continuous bamboo curtain is laid diagonally back and forth in a parallelogram shape, forming a triangular splicing in the layers. When the continuous bamboo curtain comes into contact with the main moving production line after the back and forth laying, the front end can be aligned with the back end of the continuous bamboo curtain when it was laid for the first time. The number of back and forth laying is at least once. S3, with a constant main moving production line speed, the number of bamboo curtain layers to be reciprocated and interwoven is determined by adjusting the reciprocating speed of the continuous bamboo curtain laying line.

[0005] A further improvement of the present invention on the intelligent paving method for realizing continuous bamboo curtains in a forward oblique stacking manner is that, in step S1, the connecting bamboo curtains include single or multiple layers, which are arranged in a roll or stacked manner on the continuous bamboo curtain paving line and are paved by a mobile stacking device.

[0006] A further improvement of the present invention on the intelligent paving method for realizing continuous bamboo curtains in a forward oblique superposition is that multiple sets of continuous bamboo curtain paving lines are set up, the number of which is determined according to the number of bamboo curtain layers required for the produced board, and the multiple sets of continuous bamboo curtain paving lines are arranged along the moving direction of the main moving production line.

[0007] A further improvement of the present invention on the intelligent paving method for realizing continuous bamboo curtains in a forward oblique stacking manner is that the initial paving directions of adjacent mobile stacking devices in multiple sets of continuous bamboo curtain paving lines are set in opposite directions.

[0008] Compared with the prior art, the beneficial effects of the present invention are: The present invention enables automated production of the main mobile production line and the laying line for laying continuous bamboo curtains without stopping, reducing the labor intensity of workers and improving production efficiency; the continuous laying of bamboo curtains reduces the cutting and binding processes, further improving work efficiency.

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0014] like Figure 1 and Figure 2 , 3 As shown, A smart paving method for achieving continuous bamboo curtains stacked diagonally in the forward direction includes the following steps: S1, Layout and install the main mobile production line and the continuous bamboo curtain laying line. The direction of the main mobile production line is perpendicular to the direction of the continuous bamboo curtain laying line. The continuous bamboo curtain laying line lays the continuous bamboo curtain in the direction of the continuous bamboo curtain. The main mobile production line moves in a straight line, and the continuous bamboo curtain laying line moves back and forth in a straight line. One main mobile production line is set up, and multiple continuous bamboo curtain laying lines are set up. Multiple sets of continuous bamboo curtain laying lines are laid along the moving direction of the main mobile production line. The number of bamboo curtain layers required for the production of bamboo-wood composite plywood is determined according to the number of bamboo curtain layers required. The connecting bamboo curtain includes single or multiple layers, and is laid on the continuous bamboo curtain laying line in a roll or stacked shape. The laying is achieved by a mobile stacking equipment. The mobile stacking equipment is existing equipment.

[0015] S2, the main mobile production line is running, and the continuous bamboo curtain laying line is running at the same time. At this time, the continuous bamboo curtain is laid diagonally back and forth on the main mobile production line in a parallelogram shape, forming a triangular splicing in the layers. When the continuous bamboo curtain comes into contact with the main mobile production line after the back and forth laying, the front end can be aligned with the back end of the continuous bamboo curtain in the previous laying. The number of back and forth laying is at least one. In order to ensure the neatness of the laying, since the continuous bamboo curtain will cover the lower layer and cause visual obstruction when it is laid, infrared and other control methods can be used to replace visual observation. It is preferred to control the staggered overlap to 30-50mm.

[0016] S3, with a constant main moving production line speed, the number of bamboo curtain layers to be reciprocated and interwoven is determined by adjusting the reciprocating speed of the continuous bamboo curtain laying line.

[0017] Furthermore, in multiple sets of continuous bamboo curtain laying lines, adjacent mobile stacking devices are initially laid in opposite directions. That is, the second bamboo curtain assembly unit should be arranged on both sides of the main production line with the first bamboo curtain assembly unit, forming a complementary triangle, with the bamboo strip ends interlacing in the width direction, thereby improving the bending strength of the entire board surface.

[0018] Furthermore, in S2, when laying the continuous bamboo curtain, veneer is added. The veneers are laid between the reciprocating continuous bamboo curtains, with the front and rear veneers spatially aligned. The veneer laying is currently done manually, with two groups of workers positioned on either side of the main production line. When the mobile stacking equipment moves away from that side, a worker places a veneer. Then, when the mobile stacking equipment returns to that side, the other worker places a veneer on the continuous bamboo curtain, ensuring that the front and rear veneers are spatially aligned, thereby guaranteeing that the overall thickness of the boards is consistent.

[0019] like Figure 4 , 5 As shown, after reciprocating installation, when the continuous bamboo curtain contacts the main moving production line, the front end is not aligned with the previous one, resulting in some positions having different numbers of bamboo curtain layers. Therefore, it is necessary to design and adjust the speed of the reciprocating movement to ensure that after one or more reciprocating installations, the front and rear ends of the bamboo curtain can be vertically aligned, guaranteeing a consistent number of bamboo curtain layers throughout the installation process.

[0020] The working principle of this invention is as follows: Single or multiple layers of continuous bamboo curtains are rolled or stacked and pulled to a mobile stacking device to form a continuous bamboo curtain laying line. The direction of movement of the stacking device is perpendicular to the main production line. When the main production line is static, the continuous bamboo curtain moves and stacks along a straight line, with the direction of the bamboo strips aligned with the direction of the main production line's operation, and both ends of the bamboo curtain are parallel. This is the existing production process. Now, the existing laying method is changed. The main mobile production line runs without stopping, while the continuous bamboo curtain moves and stacks along a straight line. Because the bamboo strips are woven with yarn (the weft is usually cotton, but nylon is also used), the continuous bamboo curtain has toughness and a certain degree of elasticity. The bamboo strips are successively pulled forward by the main production line, forming a diagonal parallelogram parallel to the main production line. At this time, a diagonal, reciprocating laying pattern resembling a parallelogram is formed on the main mobile production line. The speed of the main production line is generally not changed, and the paving width is not less than 1.2 meters. The faster the mobile stacking equipment runs, that is, the higher the frequency of round trips, the more layers of bamboo curtains are stacked in a diagonal and interlocking manner; conversely, the slower the mobile stacking equipment runs, the fewer layers of bamboo curtains are stacked in a diagonal and interlocking manner. According to the requirements of production process and product formula, the number of layers in each bamboo curtain assembly unit in the board is generally 2 or more (referring to single-layer bamboo curtains). When the bamboo curtain is laid quickly, the number of bamboo strips pulled by the main production line is large, the tension on the weaving thread is small, and the slant of the parallelogram is small. When the bamboo curtain is laid slowly, the number of bamboo strips pulled by the main production line is small, and the tension on the weaving thread in the warp direction perpendicular to the bamboo strips is large. Too much tension will change the parallelism between the bamboo strips and the main production line, and the laying effect will no longer be a slanted parallelogram, nor will it be parallel to the main production line. The effect of each bamboo curtain assembly unit being diagonally staggered should form a triangular splicing in terms of layering, rather than a diamond-shaped stacking (where the diamond layer exceeds the triangle layering); the second bamboo curtain assembly unit should be arranged on both sides of the main production line with the first bamboo curtain assembly unit, forming a complementary triangle, with the bamboo strip ends staggered in the width direction to improve the bending strength of the entire board surface. The layered structure of the slab can be symmetrical or asymmetrical; for symmetrical structures, the number of bamboo curtain combination units must be even; for asymmetrical structures, the number of bamboo curtain combination units must be odd. The mobile stacking equipment is driven by a servo motor, with a stroke that is the width of the main production line (currently there are three examples: one is a wide format with a width of 2.32 meters, the second is an extra-large format with a width of 4.64 meters, both of which are multiples of the original narrow format width of 1.16 meters, and the third is a multiple of 0.636 meters). This ensures that the hypotenuses of the triangular areas of each bamboo curtain combination unit are aligned, without creating gaps or secondary overlapping. A vision system is installed on the mobile stacking equipment to compare the tilt status of the bamboo curtain with the database in order to deal with some unconventional situations and achieve intelligent production.

[0021] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
