Description

Technical Field

[0001] The invention relates to the technical field of aluminum tube processing, and in particular to an automatic unloading mechanism for aluminum tube processing. Background Art

[0002] Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is made of pure aluminum or aluminum alloy through extrusion and is hollow along its entire longitudinal length. Conventional aluminum tubes have uniform wall thickness and cross-section, and are delivered in straight lines or coils. They can be widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries. The processing of aluminum tubes requires multiple processes, and the aluminum tubes need to be transported between different workstations. At the same time, the aluminum tubes need to be automatically unloaded after completing the processing of each process.

[0003] The patent document with publication number CN214454842U discloses a feeding device and an aluminum tube ring cutting production line. The feeding device includes a frame, a transmission mechanism and a pushing mechanism arranged on the frame; the transmission mechanism extends at one end along the first direction to a position close to the discharge end of the ring cutting machine, and is used to take the aluminum tube after ring cutting away from the ring cutting machine to realize the discharge of the ring cutting machine. The pushing mechanism is located above one side of the transmission mechanism along the second direction, and the frame is formed with a collection platform below the other side of the transmission mechanism along the second direction. The pushing mechanism is used to push the aluminum tube on the transmission mechanism to make it roll onto the collection platform for collection and storage. This patent can take the aluminum tube after ring cutting away from the ring cutting machine through the transmission mechanism, and with the cooperation of the pushing mechanism, push the aluminum tube to the collection platform for collection, thereby completing the unloading of the aluminum tube.

[0004] However, in the process of the aluminum tube falling from the transmission mechanism to the aggregate platform, the aluminum tube is prone to rolling around, causing the aluminum tube that falls on the aggregate platform to be deflected, making it difficult to collect. At the same time, the subsequent aluminum tubes will collide with the aluminum tube that falls on the aggregate platform, causing dents and scratches on the aluminum tube, affecting the quality of the aluminum tube. Summary of the invention

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 9 As shown, an automatic unloading mechanism for aluminum tube processing of the present invention comprises a frame 1, a conveying assembly, a receiving rack 2 and a unloading mechanism, wherein the unloading mechanism comprises a lifting assembly and a buffer assembly.

[0039] The conveying assembly includes a conveyor belt 13 arranged above the frame 1, and the conveyor belt 13 is used to convey the aluminum tube 3 after sandblasting from the sandblasting equipment 14 to the front. The receiving rack 2 is arranged on one side of the frame 1, and the upper end of the receiving rack 2 gradually tilts downward in the direction away from the frame 1. The lifting assembly is arranged on the frame 1, and is used to lift the aluminum tube 3 above the conveyor belt 13 so that the aluminum tube 3 can slide from the conveyor belt 13 to the receiving rack 2. The buffer assembly is arranged on the receiving rack 2, and is used to buffer the sliding aluminum tube 3 to prevent the aluminum tube 3 from being damaged by collision.

[0040] The lifting assembly includes a lifting rod 11 and a driving structure 1. The lifting rod 11 is arranged on the frame 1 along the width direction of the frame 1. The driving structure 1 is used to drive the lifting rod 11 to flip so that the aluminum tube 3 above the conveying assembly can roll onto the receiving rack 2. The buffer assembly includes a mounting plate 21, a buffer structure 22, a driving structure 2 and a reset structure. The mounting plate 21 is arranged on the receiving rack 2 along the inclination direction of the receiving rack 2. The buffer structures 22 are provided in plurality and are arranged at intervals at the upper end of the mounting plate 21 along the length direction of the mounting plate 21. Each buffer structure 22 includes a buffer member 221 and a rotating device The flip roller 222 on the buffer member 221 has an arc surface 1 on the side of the buffer member 221 facing the frame 1, and the arc surface 1 is set downward. The flip roller 222 is made of elastic material. The aluminum tube 3 can contact the flip roller 222 during the rolling process. The side of the receiving rack 2 away from the frame 1 is the right side. The driving structure 2 is used to drive multiple buffer structures 22 to move upward in sequence from right to left relative to the mounting plate 21 after any aluminum tube 3 rolls to the right end of the mounting plate 21. The reset structure is used to drive the buffer structure 22 to move downward relative to the mounting plate 21 for reset.

[0041] Specifically, the aluminum tube 3 is conveyed by the conveying assembly. When the aluminum tube 3 moves to the top of the lifting rod 11, the lifting rod 11 is driven to flip by the driving structure 1, so that the aluminum tube 3 can gradually roll down along the inclined lifting rod 11 to the top of the receiving rack 2, and continue to roll down along the upper end of the receiving rack 2. During this process, the aluminum tube 3 will contact the flip rollers 222 in the multiple buffer structures 22 in turn, so that the flip rollers 222 can buffer the aluminum tube 3 and space the distance between two adjacent aluminum tubes 3 to avoid collision between the aluminum tubes 3. When the lowest aluminum tube 3 moves to the right end of the mounting plate 21, the driving structure 2 is triggered to start, so that the multiple buffer structures 22 move upward in turn from right to left relative to the mounting plate 21, that is, the lowest aluminum tube 3 moves to the right end of the mounting plate 21 When the second aluminum tube 3 contacts the rightmost buffer structure 22, the second buffer structure 22 moves upward to separate the second aluminum tube 3 from the subsequent aluminum tube 3. When the third aluminum tube 3 contacts the second buffer structure 22, the third buffer structure 22 moves upward to separate the third aluminum tube 3 from the subsequent aluminum tube 3, and so on, until all the aluminum tubes 3 are separated by the buffer structure 22, so as to avoid the aluminum tube 3 on the left side from colliding with the aluminum tube 3 on the right side, so as to ensure the quality of the aluminum tube 3. In addition, in the present embodiment, the buffer assembly is provided in two groups and symmetrically arranged on the receiving rack 2, so as to limit the position of the aluminum tube 3 during the rolling process of the aluminum tube 3 to avoid the deflection of the aluminum tube 3.

[0042] In some embodiments, a mounting groove 201 is provided at the upper end of the material receiving rack 2, and the mounting plate 21 is slidably matched with the material receiving rack 2 through the mounting groove 201. The end of the mounting plate 21 close to the frame 1 is mounted above the lifting rod 11, so that when the lifting rod 11 is flipped, the mounting plate 21 can slide relative to the material receiving rack 2 along its own height direction.

[0043] Specifically, Figures 1 to 3 As shown, in the initial state, the lifting rod 11 is arranged horizontally, and the mounting plate 21 is located at the lower end of the mounting groove 201. At this time, the buffer structure 22 is completely located in the mounting groove 201, so that the height of the flip roller 222 is kept flush with the mounting groove 201, or lower than the mounting groove 201. After the lifting rod 11 is flipped upward by the driving structure 1, the mounting plate 21 erected above the lifting rod 11 will be driven to move, so that the mounting plate 21 moves upward relative to the receiving frame 2 along its own height direction, and drives the buffer structure 22 to move synchronously, so that the flip roller 222 is exposed upward. At this time, the aluminum tube 3 will contact the flip rollers 222 in the multiple buffer structures 22 in the process of rolling down, so that the flip roller 222 can buffer the aluminum tube 3 to prevent the aluminum tube 3 from rolling down. When all the aluminum tubes 3 are moved to the top of the receiving rack 2, all the aluminum tubes 3 can be separated by a plurality of buffer structures 22, so that there is a buffer structure 22 between each aluminum tube 3 to block it, so as to prevent the aluminum tube 3 on the left from colliding with the aluminum tube 3 on the right. At this time, the lifting rod 11 is flipped downward by the driving structure 1, which will drive the mounting plate 21 to move downward relative to the receiving rack 2 along its own height direction, so that the buffer structure 22 retracts into the mounting groove 201. At this time, the aluminum tube 3 will lose the obstruction of the buffer structure 22 and continue to move to the right side of the receiving rack 2 until all the aluminum tubes 3 are arranged in sequence, so that any two adjacent aluminum tubes 3 are in contact with each other, thereby reducing the gap between the aluminum tubes 3 and facilitating the subsequent centralized collection of the aluminum tubes 3 on the receiving rack 2.

[0044] It should be noted that the flip roller 222 is in the shape of a triangular prism, and each side is provided with an arc surface that matches the shape of the aluminum tube 3. During the rolling process, the aluminum tube 3 will contact any side of the flip roller 222, so that the flip roller 222 is forced to rotate, so that the aluminum tube 3 can continue to move over the flip roller 222. Through the contact between the aluminum tube 3 and the flip roller 222, the aluminum tube 3 can be buffered to prevent the aluminum tube 3 from rolling down too fast and being subjected to a large impact force when falling to the bottom, causing the aluminum tube 3 to be deformed, thereby ensuring the quality of the aluminum tube 3.

[0045] In some embodiments, both ends of the lifting rod 11 are mounted above the frame 1, the driving structure 1 includes two groups of cylinders 12, and the output ends of the two groups of cylinders 12 are respectively connected to the two ends of the lifting rod 11. In the initial state, the lifting rod 11 is horizontally arranged and is at the same height as the conveyor belt 13.

[0046] Specifically, Figures 1 to 3 As shown, in the initial state, the lifting rod 11 is horizontally arranged and is at the same height as the conveyor belt 13, so that the aluminum tube 3 on the conveyor belt 13 can gradually move to the top of the lifting rod 11, and then the two groups of cylinders 12 are started, and the output ends of the two groups of cylinders 12 are extended to different lengths, so that the end of the lifting rod 11 close to the material receiving rack 2 is lower than the other end of the lifting rod 11, so that the aluminum tube 3 above the lifting rod 11 can roll downward along the inclined lifting rod 11 and gradually roll to the top of the material receiving rack 2.

[0047] In some embodiments, the driving structure 2 includes a positioning member 23, a push rod 24, and a driving member arranged between two adjacent buffer structures 22. The positioning member 23 is arranged on the end of the mounting plate 21 away from the frame 1, and slides with the mounting plate 21 along the length direction of the mounting plate 21, and a spring 1 231 is connected between the positioning member 23 and the mounting plate 21. Two positioning blocks 232 are arranged on the positioning member 23, and there is a space between the two positioning blocks 232 for the push rod 24 to pass through, so that the push rod 24 and the positioning member 23 are relatively fixed in the length direction of the mounting plate 21 and slide relatively in the height direction of the mounting plate 21. Each buffer 221 has an arc surface 3 on the side away from the frame 1, and the arc surface 3 is arranged downward. The end of the push rod 24 away from the positioning member 23 can contact the adjacent buffer 221, and has an arc surface 4 adapted to the arc surface 3. The driving member is used to drive the adjacent buffer structure 22 on the left to move in the same direction when the adjacent buffer structure 22 on the right moves upward or downward relative to the mounting plate 21. The driving member includes a plurality of Z-shaped rods 25, and the plurality of Z-shaped rods 25 are respectively arranged corresponding to the plurality of buffer structures 22. Each Z-shaped rod 25 slides with the material receiving rack 2 along the inclined direction of the material receiving rack 2. The end of each Z-shaped rod 25 facing the frame 1 can contact the adjacent buffer structure 22 on the left, and has an arc surface five that matches the arc surface three. The other end of each Z-shaped rod 25 is provided with a locking groove 251. Each buffer member 221 is connected to a rod member 223, and the rod member 223 can be inserted into the corresponding locking groove 251, so that the Z-shaped rod 25 is locked and matched with the buffer member 221. A spring two 224 is connected between the lower end of each buffer member 221 and the mounting plate 21.

[0048] Specifically, Figures 1 to 9As shown, the lifting rod 11 is driven to flip by the driving structure 1, so that the aluminum tube 3 rolls down onto the receiving rack 2 along the inclined lifting rod 11. When the lowest aluminum tube 3 moves to the right side of the receiving rack 2 and contacts the positioning member 23, the aluminum tube 3 stops moving. At the same time, the positioning member 23 moves in the direction away from the frame 1 under the force of the aluminum tube 3, and the spring 1 231 is compressed to store force. When the positioning member 23 moves, it will drive the push rod 24 fixed relatively to the positioning member 23 in the length direction of the mounting plate 21 to move synchronously, so that the push rod 24 gradually moves away from the buffer structure 22 on the left side, so that the arc surface 4 on the push rod 24 is separated from the arc surface 3 on the buffer member 221. At this time, the buffer member 221 will move upward relative to the mounting plate 21 under the action of the spring 224. And drive the rod 223 connected thereto to move, so that the rod 223 is disengaged from the locking groove 251 provided on the corresponding Z-shaped rod 25. At this time, the Z-shaped rod 25 is in an unlocked state, so that the adjacent buffer 221 on the left side loses the force applied by the Z-shaped rod 25, so that the adjacent buffer 221 on the left side can move upward relative to the mounting plate 21 under the action of the corresponding spring 224, and push the Z-shaped rod 25 on the right side to slide in the direction away from the frame 1, and then and so on, so that the multiple buffer structures 22 move upward relative to the mounting plate 21 in sequence from right to left, so that each aluminum tube 3 can be between any two adjacent buffer structures 22, so as to separate all the aluminum tubes 3 and avoid collision of the aluminum tubes 3 during the rolling process.

[0049] In some embodiments, an elastic portion for cushioning the aluminum tube 3 is provided on the side of the positioning member 23 facing the frame 1, and an arc surface five matching the shape of the aluminum tube 3 is provided on the elastic portion, which is used to cushion the aluminum tube 3 when the aluminum tube 3 contacts the positioning member 23, thereby further preventing the aluminum tube 3 from being damaged.

[0050] In some embodiments, the reset structure includes an electric push rod 26, which is arranged on one end of the mounting plate 21 away from the frame 1, and the output end is connected to the positioning member 23. Each Z-shaped rod 25 is provided with an inclined surface, which gradually tilts downward from left to right, and the end of the inclined surface is connected to the lock slot 251.

[0051] Specifically, Figure 1 , Figure 5 , Figure 6 and Fig. 9As shown, after all the aluminum tubes 3 are moved from above the conveyor belt 13 to above the receiving rack 2, the electric push rod 26 is started to drive the positioning member 23 to move toward the direction close to the rack 1, and drive the push rod 24 to move synchronously. In this process, the arc surface 3 on the adjacent buffer 221 can cooperate with the arc surface 4 on the push rod 24, so that the buffer 221 can move downward relative to the mounting plate 21, and drive the rod 223 connected to the buffer 221 to move downward. In this process, the rod 223 can cooperate with the corresponding inclined surface on the Z-shaped rod 25. The cooperation of the surfaces enables the Z-shaped rod 25 to move toward the direction close to the frame 1 until the rod 223 is reinserted into the locking groove 251 provided on the Z-shaped rod 25, so that the Z-shaped rod 25 and the buffer 221 are locked and cooperated. During the movement of the Z-shaped rod 25, the arc surface three on the buffer 221 adjacent to it on the left side cooperates with the arc surface five on the Z-shaped rod 25, so that the buffer 221 moves downward relative to the mounting plate 21, and so on, so that the multiple buffer structures 22 move downward in sequence from right to left relative to the mounting plate 21 to be reset.

[0052] In some embodiments, a plurality of mounting openings 211 are provided on the mounting plate 21 at intervals along its length direction, a slider 212 is slidably provided in each mounting opening 211, the plurality of sliders 212 are respectively provided corresponding to the plurality of buffer structures 22, and are connected to the buffer members 221 in the buffer structures 22, and a spring three 213 is connected between the slider 212 and the side wall of the mounting opening 211.

[0053] Specifically, Figures 3 to 8 As shown, when the rod 223 is disengaged from the locking groove 251, the buffer structure 22 is in an unlocked state, so that the buffer 221 can move upward relative to the mounting plate 21 under the action of the spring 224. At this time, the aluminum tube 3 will touch the buffer 221 during the downward rolling process, so that the buffer 221 is forced to slide in the direction close to the positioning member 23, and the spring 3 213 is compressed to store force. Through the movement of the buffer 221, the aluminum tube 3 can be further buffered to prevent the aluminum tube 3 from being damaged by collision.

[0054] In some embodiments, a plurality of slide grooves are provided on the receiving rack 2 at intervals along its length direction, each slide groove is arranged along the inclination direction of the receiving rack 2, each Z-shaped rod 25 is slidably matched with the receiving rack 2 through the corresponding slide groove, and a spring four 252 is connected between the receiving rack 2.

[0055] Specifically, Figures 2 to 6As shown, the buffer structure 22 is moved upward relative to the mounting plate 21 by driving structure 2, and after the rod 223 is driven to disengage from the locking groove 251, the Z-shaped rod 25 is in an unlocked state. At this time, the Z-shaped rod 25 will move along the sliding groove under the action of spring four 252, so that the Z-shaped rod 25 gradually moves away from the adjacent buffer structure 22 on the left, and the arc surface five on the Z-shaped rod 25 is separated from the arc surface three on the corresponding buffer component 221. At this time, the buffer component 221 adjacent to it on the left will lose the force applied by the Z-shaped rod 25, and move upward relative to the mounting plate 21 under the action of spring two 224. By setting spring four 252, the Z-shaped rod 25 can be quickly moved after the rod 223 is disengaged from the locking groove 251, thereby avoiding obstruction to the movement of the buffer structure 22.

[0056] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
