[0002] Laser tube cutting machines are efficient and precise tube processing equipment widely used in metal processing, automotive manufacturing, aerospace, and construction engineering. In actual production, the tube feeding method directly affects production efficiency and processing accuracy. Traditional feeding methods typically rely on manual or semi-automatic feeding racks, resulting in low feeding efficiency, high labor intensity, uneven tube placement, and the potential for tube stacking or misalignment, thus affecting cutting accuracy and increasing scrap rates. Partially automatic or semi-automatic feeding racks require manual adjustment of multiple positions to automatically feed tubes of different sizes. Since these adjustments are done manually, the accuracy and effectiveness are difficult to guarantee, leading to multiple adjustments and the risk of misoperation, significantly wasting time, impacting production progress, and easily introducing errors, affecting production stability. Therefore, designing a highly efficient, stable, and fully automatic feeding rack capable of adapting to different tube specifications is of great significance for improving the automation level and production efficiency of laser tube cutting machines.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0062] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0063] Please refer to the following: A fully automatic feeding rack for a laser tube cutting machine. Figure 1-7The system includes a loading rack 100 located on one side of a laser tube cutting machine for feeding tubes. The laser tube cutting machine is a cutting machine tool, and its model and size are not limited. It is typically used to cut tubes of different shapes or sizes. The loading rack 100 is usually connected to the laser tube cutting machine, and the tubes are automatically fed from the loading rack 100 to the tube cutting machine for cutting. The loading rack 100 includes a tensioning assembly 110, a pressing assembly 120, a blocking assembly 130, and a follower assembly 140. The loading rack 100 has a frame structure, and each component is respectively mounted on the frame structure. The tensioning assembly 110 includes multiple tensioning straps 111 and multiple feed support bars 112 with an inclined structure near the tube cutter. The tensioning assembly 110 can move the tube via the tensioning straps 111 to allow the tube to slide onto the feed support bars 112. Since the feed support bars 112 are inclined downwards towards the tube cutter, the tube reaching the top of the feed support bars 112 will slide downwards on its own. The end of the feed support bar 112 near the laser tube cutter is connected to a receiving groove 113 to accommodate the sliding tube. In this embodiment, there are 4 tensioning straps 111, and 7 feed support bars 112 and 7 receiving grooves 113. However, the number of tensioning straps 111 and feed support bars 112 is not limited to this embodiment. Multiple feed support bars 112 jointly support the tube to ensure stable sliding of the tube.

[0064] Furthermore, three pressing assemblies 120 are provided, and each pressing assembly 120 is connected in parallel by a coupling 121 and a connecting shaft 122. Each pressing assembly 120 has a sliding plate 123 that can move closer to or further away from the feed support bar 112. The sliding plate 123 and the feed support bar 112 form a space for individual pipes to slide down. The bottom surface of the sliding plate 123 is parallel to the feed support bar 112. The pipes slide down onto the feed support bar 112 after being stretched. Since the sliding plate 123 restricts the distance between itself and the feed support bar 112, the sliding pipes can be arranged in a row to prevent pipes from stacking. When feeding pipes of different diameters, the distance between itself and the feed support bar 112 can be changed by controlling the movement of the sliding plate 123, so that pipes of different diameters can slide down in a single row.

[0065] Furthermore, there are three material blocking components 130, each corresponding to a material pressing component 120. Each material blocking component 130 has a movable baffle 131. The baffle 131 moves to block / allow the pipe on the feed support bar 112 to slide into the receiving groove 113. There are four follower components 140. Each follower component 140 can move up and down and is connected to the loading rack 100. Each follower component 140 has rollers 141. The rollers 141 can lift the pipe in the receiving groove 113 by moving upward through the follower components 140. When the pipe is fed into the receiving groove 113, it is then lifted by the rollers 141, thus completing the entire loading process. Generally, the pipe cutting machine has a front clamp or a rear clamp that can hold the pipe. After the pipe is clamped, it is laser cut. At the same time, the pipe being supported by the rollers 141 can improve the stability during cutting and ensure cutting accuracy.

[0066] Furthermore, the pressing assembly 120 is equipped with a pressing plate 124 that can move towards / away from the feed support bar 112, and a first cylinder 126 that connects the movement of the pressing plate 124. Each first cylinder 126 can operate simultaneously, driving multiple pressing plates 124 to press against the pipe on the feed support bar 112. Once the pipe is pressed, it stops sliding; after the pressing plate 124 is released, the pipe continues to slide. The loading rack 100 is equipped with multiple first slide rails 101 connecting to the blocking assembly 130. The blocking assembly 130 can adjust the distance between the baffle 131 and the pressing plate 124 by moving along the first slide rails 101. Depending on the diameter of the pipe being loaded, the blocking assembly 130 can be controlled to slide, matching the distance between the baffle 131 and the pressing plate 124 to the pipe size, ensuring that only one pipe can slide into the receiving groove 113 and then be lifted by the follower assembly 140. Specifically, the pressing plate... A distance of one pipe is maintained between 124 and baffle 131. When the pipes form a row from the feed support bar 112, baffle 131 blocks the entire row of pipes from sliding down. Then, pressure plate 124 presses down on the pipes. The distance has been adjusted to ensure that pressure plate 124 can press down on at least the second pipe closest to receiving groove 113. Except for the pipe closest to receiving groove 113, the other pipes are pressed down and cannot slide down. Then, baffle 131 moves so that the pipe can slide smoothly into receiving groove 113.

[0067] Furthermore, multiple material blocking assemblies 130 are respectively connected to material blocking drive shafts 132. The loading rack 100 is equipped with a material blocking motor 133 and a material blocking reducer 134 connected to the material blocking drive shafts 132. The material blocking drive shafts 132 are equipped with material blocking gears 135 connected to the material blocking assemblies 130. The material blocking assemblies 130 are equipped with a material blocking rack 136 connected to the material blocking gears 135. The material blocking assemblies 130 are equipped with a material blocking cylinder 137 connected to and capable of driving the baffle 131 to move up and down. The material blocking cylinder 137 controls the movement of the baffle 131 to achieve the blocking or release of the first pipe. The material blocking drive shaft 132 connects multiple material blocking components 130, and the multiple material blocking components 130 are linked together through the drive of the material blocking motor 133 and the material blocking reducer 134, as well as the cooperation of the material blocking gear 135 and the material blocking rack 136. This facilitates quick adjustment of the material blocking components 130 to adapt to different sizes of pipes, eliminating the need for operators to manually adjust them one by one, improving production efficiency, and making material feeding more stable.

[0068] Furthermore, the tensioning assembly 110 is equipped with a tensioning motor 114 and a tensioning drive shaft 117 that can be driven by the tensioning motor 114. The tensioning drive shaft 117 is equipped with fixed wheels 116 that connect to each tensioning belt 111. The tensioning belt 111 is tightened or loosened by the drive of the tensioning motor 114. The loading rack 100 is equipped with a frame corresponding to the position of the tensioning belt 111 to place multiple tubes. The multiple tensioning belts 111 are respectively connected to the fixed wheels 116 on the tensioning drive shaft 117. The tensioning motor 114 is connected to the tensioning drive shaft 117 through a chain, which can simultaneously drive the tensioning belts 111 to tighten at the same time. When the tensioning belts 111 are tightened, multiple tubes are lifted, so that the tubes at the top reach the feeding support bar 112 and slide down.

[0069] Furthermore, the pressing assembly 120 is equipped with a lifting device 127 that connects to the slide plate 123. The lifting devices 127 on each pressing assembly 120 are connected by a connecting shaft 122 and a coupling 121 respectively. The feeding rack 100 is equipped with a pressing motor 125 that connects to the connecting shaft 122 and can drive the lifting device 127. Driven by the pressing motor 125, the lifting device 127 connected by the coupling 121 and the connecting shaft 122 simultaneously drives the slide plate 123 to move away from / near the feeding support bar 112, realizing multiple linkages. This facilitates feeding adjustment according to the pipe size and ensures that pipes of different sizes can form a row of slides.

[0070] Furthermore, the loading rack 100 is equipped with multiple follower slide rails 102 connecting follower components 140. Each follower component 140 is connected to a follower drive shaft 142. The loading rack 100 is equipped with a follower motor 143 connected to and capable of driving the follower drive shafts 142. The follower drive shaft 142 is equipped with a follower gear 144 connecting to the follower components 140. Each follower component 140 is equipped with a follower rack 145 connecting to the follower gear 144. The follower motor 143 drives the follower drive shaft 142. Through the cooperation of the follower gear 144 and the follower rack 145, the multiple follower components 140 move in unison, rising or falling simultaneously to stably support the pipe and ensure processing accuracy. This invention enables fully automated pipe feeding without manual intervention, thus improving production efficiency. Multiple identical components are linked together to achieve rapid and efficient adjustment of corresponding positions. Stable feeding is ensured for pipes of different sizes, reducing the occurrence of failures. The fully automated feeding and lifting of the pipes for cutting ensures cutting accuracy and reduces the number of defective products.
