Description

Technical Field

[0001] This utility model relates to the field of bamboo and wood processing machinery technology, and in particular to a vertical bamboo tube transfer and conveying production line. Background Technology

[0002] In the primary processing of moso bamboo, the raw bamboo is first cut into the required lengths. Generally, the raw bamboo is cut into bamboo tubes (i.e., bamboo segments) of the required length using a bamboo sawing machine. This sawing operation is called bamboo segmenting or bamboo length setting. Then, the piles of bamboo tubes are manually sorted (based on specifications such as diameter, wall thickness, and surface defects). Bamboo tubes with the same wall size are sent to the corresponding bamboo splitting machine (also known as a bamboo splitting machine) for splitting to obtain bamboo strips of the set width. This splitting operation is called bamboo splitting.

[0003] Taking the bamboo tube transfer connection between the bamboo sawing machine and the bamboo splitting machine as an example, in the current bamboo tube transfer process, workers use handcarts to move piles of bamboo tubes (i.e., bamboo segments) of the same wall size to the bamboo splitting machine, and then perform the splitting operation. The current bamboo tube transfer connection method is all done by manual handling by workers, which is inefficient, labor-intensive, and lacks continuous operation capacity, resulting in very low efficiency in bamboo tube transfer connection work. Utility Model Content

[0004] This utility model provides a vertical bamboo tube transfer and conveying production line to overcome the problems of existing bamboo tube transfer and connection methods, which all rely on manual handling by workers, resulting in high labor intensity, inability to achieve automated continuous processing, and extremely low efficiency in bamboo tube transfer and connection work.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An overpass-type bamboo tube transfer and conveying production line includes a first conveyor line and a second conveyor line that are crisscrossed and form an overpass structure. The first conveyor line is located below the second conveyor line and the conveying directions of the first conveyor line and the second conveyor line are perpendicular. It also includes a lifting and turning mechanism that selectively lifts and transfers bamboo segments (i.e., bamboo tubes) on the first conveyor line to the corresponding conveyor belts of the second conveyor line according to their specifications and dimensions. The starting end of the first conveyor line is located at the discharge end of the bamboo saw and is used to receive bamboo segments (i.e., bamboo tubes) on the bamboo saw. The ending end of the second conveyor line is located at the feeding end of the bamboo splitting machine and is used to supply bamboo segments (i.e., bamboo tubes) on the corresponding conveyor belts to the feeding end of the corresponding bamboo splitting machine.

[0007] Furthermore, the first and second conveyor lines form a crisscrossing double-layered overpass structure; the first conveyor line includes multiple first conveyor belts arranged in sequence, and the second conveyor line includes multiple second conveyor belts arranged in sequence, with the end of each second conveyor belt corresponding to the feeding end of a bamboo slicing machine; the starting end of each first conveyor belt receives bamboo segments (i.e., bamboo tubes) from the bamboo sawing machine; the lifting and turning mechanism is located at the intersection between the first and second conveyor belts, and the bamboo segments (i.e., bamboo tubes) on the first conveyor belts are sized according to specifications (e.g., diameter, etc.). Wall thickness Requirements such as size and surface defects are selectively lifted and transferred to the corresponding second conveyor belt by the lifting and turning mechanism, and then the second conveyor belt continues to transport it to the feeding end of the corresponding bamboo shaving machine for shaving.

[0008] Furthermore, the plurality of first conveyor lines are arranged in a straight line or in an L-shape; the bamboo segments (i.e., bamboo tubes) on each L-shaped first conveyor line are conveyed at right angles through a turning conveyor mechanism.

[0009] Furthermore, the bamboo sawing machine is a multi-station bamboo sawing machine. The starting end of one conveyor belt of the first conveyor line is located below one cutting attachment of the bamboo sawing machine. The starting end of the conveyor belt is used to receive the bamboo segments (i.e., bamboo tubes) formed by the corresponding cutting blades. Each cutting attachment is equipped with an identification element (i.e., an industrial camera such as a CCD camera, which is connected to the control center of the bamboo sawing machine). The identification element is used to acquire images of the bamboo cross-section to obtain information on the diameter and wall thickness of the bamboo segment cross-section.

[0010] Furthermore, the bamboo sawing machine is a single-station bamboo sawing machine. The starting end of one conveyor belt of the first conveyor line is located below the pulling assembly of the bamboo sawing machine. The starting end of the conveyor belt is used to receive the bamboo segments (i.e., bamboo tubes) formed by the cutting assembly. The diameter and wall thickness information of the bamboo segment cross-section are obtained by the bamboo cross-section image obtained by the identification element on the pulling assembly (i.e., an industrial camera such as a CCD camera, which is connected to the control center of the bamboo sawing machine).

[0011] Furthermore, the bamboo saw is also equipped with a second recognition element (such as an industrial camera, such as a CCD camera, which is connected to the control center of the bamboo saw) at the rear for acquiring images of the bamboo tubes to obtain information on surface defects and curvature of the bamboo segments.

[0012] Furthermore, each lifting and turning mechanism is also equipped with a feeding device that acts as a buffer. The feeding device includes at least two sets of lifting mechanisms and at least one set of transition beams. A set of transition beams is set between each pair of adjacent lifting mechanisms, and the transition beams are inclined. The purpose of setting up the feeding device is to receive the bamboo tubes on the lifting and turning mechanism and feed them up step by step to the corresponding conveyor belt of the second conveyor line.

[0013] Furthermore, the turning transmission mechanism includes a horizontally arranged third conveyor belt and a fourth conveyor belt, and the conveying directions of the third conveyor belt and the fourth conveyor belt are perpendicular to each other. The outer wall of the fourth conveyor belt is provided with a vertically arranged guide conveyor belt, and the conveying direction of the guide conveyor belt is consistent with the conveying direction of the fourth conveyor belt. One end of the bamboo tube on the third conveyor belt abuts against the guide conveyor belt and is turned and turned onto the fourth conveyor belt by the traction of the guide conveyor belt for continued conveying.

[0014] Furthermore, the lifting and steering mechanism includes a lifting frame that lifts the bamboo tube upwards and a steering frame that grabs the bamboo tube on the lifting frame and turns it for placement.

[0015] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: the structural design of this bamboo tube transfer and conveying production line and method is ideal, and the use of a vertical, high-efficiency bamboo tube transfer and conveying method makes the bamboo tube transfer connection smoother, greatly improving the connection efficiency of bamboo tube transfer and conveying; according to the pre-set diameter of the bamboo tube, Wall thickness The system meets stringent requirements regarding dimensions, surface defects, and whether the curvature is excessive. It enables stable, orderly, and efficient bamboo tube transfer and conveying, resulting in greater precision, a higher level of intelligence, reduced labor intensity for workers, significant cost savings in bamboo tube transfer, and continuous operation of bamboo tube transfer and conveying.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] See attached document Figure 1 and Figure 2 A vertical bamboo tube transfer and conveying production line includes a first conveyor line and a second conveyor line that are crisscrossed and form a vertical structure. The first conveyor line is located below the second conveyor line and the conveying directions of the first and second conveyor lines are perpendicular to each other. It also includes a lifting and turning mechanism 3 that selectively lifts and transfers bamboo segments (i.e., bamboo tubes) on the first conveyor line to the corresponding conveyor belts of the second conveyor line according to dimensional requirements (such as length and diameter). The starting end of the first conveyor line is located at the discharge end of the bamboo sawing machine 4 and is used to receive bamboo segments (i.e., bamboo tubes) on the bamboo sawing machine 4. The ending end of the second conveyor line is located at the feeding end of the bamboo splitting machine 5 and is used to supply bamboo segments (i.e., bamboo tubes) on the corresponding conveyor belts to the feeding end of the corresponding bamboo splitting machine 5. Specifically, the first and second conveyor lines form a crisscrossing double-layer overpass structure. The first conveyor line includes multiple first conveyor belts 1 arranged in a straight line. The second conveyor line includes multiple second conveyor belts 2 arranged in a straight line, with the end of each second conveyor belt 2 corresponding to the feeding end of a bamboo splitting machine 5. The starting end of each first conveyor belt 1 receives bamboo segments (i.e., bamboo tubes) from the bamboo sawing machine 4. The lifting and turning mechanism 3 is located at the intersection between the first conveyor belts 1 and the second conveyor belts 2, and the bamboo segments (i.e., bamboo tubes) on the first conveyor belts 1 are cut according to specifications (such as diameter, etc.). Wall thickness The dimensions, surface defects, and excessive curvature of bamboo are selectively lifted and transferred to the corresponding second conveyor belt 2 by the lifting and turning mechanism 3, and then conveyed by the second conveyor belt 2 to the feeding end of the corresponding bamboo shaving machine 5 for shaving.

[0028] See attached document Figure 1The bamboo sawing machine 4 is a multi-station bamboo sawing machine. The starting end of a first conveyor belt 1 of the first conveyor line is located below a cutting attachment 41 of the bamboo sawing machine 4. The starting end of the first conveyor belt 1 is used to receive the bamboo segments (i.e., bamboo tubes) formed by the corresponding cutting blades. Each cutting attachment 41 is equipped with an identification element (i.e., an industrial camera such as a CCD camera, which is connected to the control center of the bamboo sawing machine 4). The identification element is used to acquire images of the bamboo cross-section to obtain information on the diameter and wall thickness of the bamboo segment cross-section. The specific structure and working principle of this multi-station bamboo sawing machine are common in the field, such as a bamboo sawing machine disclosed in the Chinese Patent Database (Patent No.: ZL202223459964.1, Authorization Date: 2023.09.26). The specific structure and working principle of the bamboo sawing machine 4 in this application are basically the same as those of the bamboo sawing machine. Furthermore, adding an identification element to the bamboo sawing machine is also a common technique in the field, such as the second identification element 32 mentioned in a bamboo sawing machine disclosed in the Chinese Patent Database (Patent No.: ZL 202320814326.2, Authorization Date: 2023.09.15). Therefore, the specific structure and working principle of the bamboo sawing machine 4 in this application will not be described in detail. The information data acquired by the identification element... Transmit to Control Center Process it, and on the obtained Information and data Storage management (such as sending to a cloud server) It will be used for recognition training with a large amount of data in the future.

[0029] Alternatively, the bamboo sawing machine can also be a single-station bamboo sawing machine. The starting end of a first conveyor belt 1 of the first conveyor line is located below the pulling assembly of the bamboo sawing machine. This starting end of the first conveyor belt 1 is used to receive the bamboo segments (i.e., bamboo tubes) formed by the cutting assembly. The diameter and wall thickness information of the bamboo segment cross-section are obtained by acquiring images of the bamboo cross-section through an identification element on the pulling assembly (i.e., an industrial camera such as a CCD camera, which is communicatively connected to the control center of the bamboo sawing machine). This single-station bamboo sawing machine can be a type of bamboo sawing machine disclosed in the Chinese Patent Database (Patent No.: ZL 202320814326.2, Authorization Date: 2023.09.15).

[0030] See attached document Figure 1The bamboo sawing machine 4 is further equipped with a second identification element 6 at the rear for acquiring images of the bamboo tubes. This second identification element 6 is an industrial camera (such as a CCD camera), which is connected to the control center of the bamboo sawing machine 4. The second identification element 6 can be placed in the center of the U-shaped bracket 61, with its camera positioned directly above the first conveyor belt 1 (at a height of 2.5 meters above the conveying plane of the first conveyor belt 1), and at a 45-degree angle to the conveying plane of the first conveyor belt 1. The design of the second identification element 6 effectively identifies whether the bamboo tubes on the first conveyor line have surface defects such as rottenness, cracks, cuts, or wormholes, as well as excessive curvature. This prevents the lifting and turning mechanism 3 from transferring bamboo tubes with surface defects or excessive curvature to the corresponding conveyor belt on the second conveyor line, effectively improving the pass rate of bamboo slices obtained after the bamboo tubes are sliced ​​by the bamboo slicing machine 5. The information data acquired by the second identification element 6... Transmit to Control Center Process it, and on the obtained Information and data Storage management (such as sending) (to the cloud server), which will facilitate the use of large amounts of data for recognition and training in the future.

[0031] See attached document Figure 1 and Figure 2 Each lifting and turning mechanism 3 is also equipped with a feeding device 7 that acts as a buffer. This feeding device 7 includes a storage rack, at least two sets of lifting mechanisms, and at least one set of transition beams. A set of transition beams is positioned between each pair of adjacent lifting mechanisms, and the transition beams are inclined. The purpose of the feeding device 7 is to receive the bamboo tubes on the lifting and turning mechanism 3 and feed them step-by-step to the corresponding second conveyor belt 2 of the second conveyor line. The design of the feeding device 7 buffers the bamboo tubes supplied to the second conveyor line, preventing the bamboo tubes from accumulating on the second conveyor line and affecting the progress of the entire bamboo tube transfer process. This results in high efficiency in bamboo tube transfer and connection. It has a strong ability to operate continuously. The feeding device 7 is basically the same as the storage rack 10 and the first feeding device 20 in an automated bamboo splitting production line disclosed in the Chinese Patent Database (Patent No.: ZL 202122662424.2, Authorization Date: 2022.04.26). Therefore, the specific structure and working principle of the feeding device 7 in this application will not be described in detail here.
