Description

Technical Field

[0001] This invention relates to the field of aluminum profile coating technology, specifically to an unloading device and unloading method for an aluminum profile coating production line. Background Technology

[0002] During the processing of aluminum profiles, a protective coating needs to be sprayed onto their surface to extend their service life. Due to the considerable length of the aluminum profiles, to ensure a uniform coating and prevent damage from collisions with other objects after coating, hooks are typically used to suspend the profiles. Guide rails then guide the suspended profiles, and coating is performed during their movement. Because the guide rails for suspending the profiles are quite high and the profiles are long, unloading the profiles requires removing them from the hooks, laying them flat, and then transferring them to a horizontal belt conveyor. This process would be cumbersome and could be further improved. Summary of the Invention

[0012] Furthermore, the unloading method of the unloading device in this aluminum profile coating production line has the following specific steps:

[0013] S1. The aluminum profile is suspended on the hook and moves with the suspension slide. After the aluminum profile is coated, it moves with the suspension slide to the upper horizontal track and moves from left to right. During this process, the aluminum profile is in a vertical state.

[0014] S2. As the aluminum profile moves from left to right along the upper horizontal track with the suspension slide, the vertical aluminum profile abuts against the top of the lifting conveyor belt. The rotating roller is driven by the motor to rotate, the ring belt moves, the push rod intervals the aluminum profile and pushes the aluminum profile to the right, so that one end of the aluminum profile is hung on the hook and the other end abuts against the top of the ring belt. When the suspension slide moves along the inclined track, the inclination angle of the aluminum profile gradually decreases until the aluminum profile is horizontal.

[0015] S3. When the aluminum profile moves to support the lower half of the conveyor belt, the aluminum profile adheres to the top of the first and second lower inclined sections and continues to move downward. After the aluminum profile separates from the conveyor belt, one end of the aluminum profile is hung on the hook and its lower surface adheres to the third horizontal section.

[0016] S4. The motor drives one of the pulleys to rotate, which in turn drives the other pulley to rotate. Thus, the two connecting shafts rotate synchronously, driving the pulley to rotate. In turn, the drive belt drives the pulley and the rotating arm to rotate.

[0017] S5. By rotating the two rotating arms distributed on the left and right in sync, the L-shaped plate is lifted from the bottom of the aluminum profile along the arc path and transferred to the upper left end of the belt conveyor. During the upward movement of the aluminum profile, the aluminum profile is disengaged from the hook. Then the aluminum profile moves to the right with the belt conveyor to complete the unloading.

[0018] Compared with the prior art, the present invention provides an unloading device and method for an aluminum profile coating production line, which has the following beneficial effects: In this unloading device and method, as the aluminum profile moves from left to right along the upper horizontal track following the suspended slide, the vertical aluminum profile abuts against the top of the lifting conveyor belt. A motor drives the rotating roller to rotate, the annular belt moves, and a push rod intervals the aluminum profile and pushes it to the right, so that one end of the aluminum profile is hooked onto the hook and the other end abuts against the top of the annular belt. As the suspended slide moves along the inclined track, the inclination angle of the aluminum profile gradually decreases until the aluminum profile is horizontal; thereby achieving automatic unloading... The purpose of this aluminum profile unloading device and method in the aluminum profile coating production line is to automatically unload the aluminum profile from the hook. The device is driven by a motor to rotate one of the pulleys, which in turn rotates the other pulley via a transmission belt. This causes the two connecting shafts to rotate synchronously, driving the pulleys and rotating arms to rotate. The synchronous rotation of the two rotating arms, distributed to the left and right, lifts the L-shaped plate along an arc path from below the aluminum profile upwards, transferring it to the upper left end of the belt conveyor. During this upward movement, the aluminum profile detaches from the hook and then moves to the right with the belt conveyor, completing the unloading process. This achieves the goal of automatically unloading the aluminum profile from the hook. Attached Figure Description

[0035] The technical solutions of this invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] Please see Figures 1-2 An unloading device for an aluminum profile coating production line includes an unloading guide rail 100. From left to right, the unloading guide rail 100 is provided with an upper horizontal rail 101, an inclined rail 102, and a lower horizontal rail 103. The connection points of the upper horizontal rail 101 and the inclined rail 102, and the connection points of the inclined rail 102 and the lower horizontal rail 103, form an arc-shaped transition. Multiple equidistantly distributed suspension slides 200 are slidably connected to the bottom of the unloading guide rail 100. The multiple suspension slides 200 are connected by connecting belts 300, which are slidably connected within the unloading guide rail 100; thus, the multiple suspension slides 200 can maintain synchronization when moving. Hooks 400 are fixedly installed at the bottom of the suspension slides 200, and the aluminum profiles are suspended on the hooks 400. In practice, the track used for aluminum profile coating is circular in shape, similar to a roller coaster track. The unloading guide rail 100 is part of the circular track used for aluminum profile coating and is used as the track for the unloading section. The connecting belt 300 is set in a circular shape corresponding to the circular track and moves within the circular track. The suspension slide 200 is equipped with a drive source to drive the suspension slide 200 to move on the unloading guide rail 100.

[0037] It also includes a lifting conveyor belt 500, which is higher on the left and lower on the right. The left end of the lifting conveyor belt 500 is located behind the upper horizontal rail 101 and is lower than the height of the upper horizontal rail 101. The right end of the lifting conveyor belt 500 is located in front of the lower horizontal rail 103 and is lower than the height of the lower horizontal rail 103. Thus, as the aluminum profile moves from left to right along the unloading guide rail 100, the aluminum profile will adhere to the top of the lifting conveyor belt 500. The lifting conveyor belt 500 lifts the bottom end of the aluminum profile while pushing the aluminum profile to the right. As the height difference between the lifting conveyor belt 500 and the hook 400 gradually decreases, the aluminum profile gradually deflects to a horizontal state.

[0038] A temporary storage rack 600 is installed between the right end of the lifting conveyor belt 500 and the unloading guide rail 100. A transverse conveying assembly 700 is installed to the right of the temporary storage rack 600. Three sets of transfer assemblies 800 are installed between the temporary storage rack 600 and the transverse conveying assembly 700, and a drive assembly 900 connects the three sets of transfer assemblies 800. When the aluminum profile is deflected to a horizontal position, it moves to the top of the temporary storage rack 600, where it is temporarily stored. Then, the drive assembly 900 and the transfer assemblies 800 work together to transfer the aluminum profile to the top of the transverse conveying assembly 700, and during this process, the aluminum profile is removed from the hook 400.

[0039] Please see Figure 3 and Figure 4 The unloading guide rail 100 has an inverted U-shaped cross-section, and support plates 104 are fixedly installed on the bottom of both side walls of the unloading guide rail 100. The suspension slide 200 includes a box-shaped slide 201 fixedly installed at the bottom of the connecting belt 300. Both sides of the box-shaped slide 201 are provided with traveling wheels 202. A drive source is installed inside the box-shaped slide 201 to drive the traveling wheels 202 to rotate, and the traveling wheels 202 roll on top of the support plates 104. A vertical rod 203 is fixedly installed at the bottom of the box-shaped slide 201, and the vertical rod 203 passes through the gap between the two sets of support plates 104. A hook 400 is fixedly installed on the bottom end of the vertical rod 203.

[0040] A base 204 is fixedly mounted on the circumferential surface of the vertical rod 203. A slide table 205 is slidably connected to the surface of the vertical rod 203, and the slide table 205 is located above the base 204. Two clamping wheels 206 are provided on the top of the slide table 205, and the two clamping wheels 206 roll against the bottom of the two support plates 104 respectively. Thus, the traveling wheel 202 and the clamping wheels 206 clamp the upper and lower sides of the support plate 104, making the movement of the suspended slide 200 on the unloading guide rail 100 more stable. Two slide rods 207 are fixedly mounted on the bottom of the slide table 205. The slide rods 207 pass through the base 204 and are slidably connected to the base 204. A spring 208 is sleeved on the outside of the slide rod 207, and the spring 208 is fixedly installed between the bottom of the slide table 205 and the top of the base 204. The elasticity of the spring 208 allows the slide 205 and the clamping wheel 206 to be raised and lowered to accommodate the transition area at the connection between the upper horizontal rail 101 and the inclined rail 102, and at the connection between the inclined rail 102 and the lower horizontal rail 103.

[0041] Please see Figure 5The lifting conveyor belt 500 includes two sets of support frames 501, with two rotating rollers 502 rotatably connected between them. The two rollers 502 are located at opposite ends of the support frames 501 and are connected by an annular belt 503. A motor 504 is fixedly mounted at the center of the right-hand roller 502. Fixed plates 505 are equidistantly fixed to the outer surface of the annular belt 503, and push rods 506 are fixedly mounted on the surface of the fixed plates 505. The fixed plates 505 lift the aluminum profiles, and the push rods 506 space the aluminum profiles together. During the movement of the annular belt 503, the push rods 506 can push the aluminum profiles to the right.

[0042] Please see Figure 1 The transverse conveying assembly 700 includes three sets of belt conveyors 701, which are equidistantly distributed along the front-to-back direction. The top of each belt conveyor 701 is lower than the hook 400 at the bottom of the lower transverse track 103. A connecting shaft 702 connects the right ends of the three sets of belt conveyors 701, and a motor 703 is fixedly mounted at the front end of the connecting shaft 702. Each belt conveyor 701 includes multiple drive wheels 7011 equidistantly distributed from left to right, connected by a support belt 7012. The connecting shaft 702 passes through and is fixed at the center of the three rightmost sets of drive wheels 7011. The three sets of belt conveyors 701 support the bottom of the aluminum profile, allowing the aluminum profile to move stably to the right.

[0043] Please see Figure 6The temporary storage rack 600 is located at its right end within the gap between the three sets of belt conveyors 701. The temporary storage rack 600 includes three arches: arch 1 601, arch 2 602, and arch 3 603, all fixedly installed on the ground. Arch 1 601 is located behind arch 2 602, and both arches 1 601 and arch 2 602 are located within the gap between the three sets of belt conveyors 701. Arch 3 603 is located in front of the transverse conveyor assembly 700. From left to right, the top of arch 1 601 is provided with an upward section 6011, a downward inclined section 6012, and a horizontal section 6013. From left to right, the top of arch 2 602 is provided with an upward section 6021, a downward inclined section 6022, and a horizontal section 6023. The top of arch 3 603 is provided with a horizontal section 6031. The inclination angle of the first inclined section 6012 is greater than that of the second inclined section 6022. The heights of the first horizontal section 6013, the second horizontal section 6023, and the third horizontal section 6031 are equal and lower than the top height of the belt conveyor 701. The lengths of the first horizontal section 6013 and the second horizontal section 6023 are equal, while the length of the third horizontal section 6031 is greater than that of the first horizontal section 6013 and the second horizontal section 6023. During the process of the aluminum profile deflecting from a vertical state to a horizontal state, the first inclined section 6012 and the second inclined section 6022 support the aluminum profile. After the aluminum profile is in a horizontal state, the first horizontal section 6013, the second horizontal section 6023, and the third horizontal section 6031 support it and temporarily store the aluminum profile.

[0044] Please see Figures 7-8 Three sets of transfer components 800 are respectively installed in front of three sets of belt conveyors 701. Each set of transfer components 800 includes two sets of uprights 801 distributed on the left and right. A pulley 802 is rotatably connected to the front top of the upright 801. A rotating arm 803 is fixedly installed on the rear top of the upright 801. A fixed column 804 is fixedly installed on the rear other end of the rotating arm 803. An L-shaped plate 805 is connected between the two sets of fixed columns 804, and the fixed column 804 and the L-shaped plate 805 are rotatably connected. A fixed shaft is fixedly installed between the rotating arm 803 and the pulley 802. The fixed shaft passes through and is rotatably connected to the upright 801, so that the pulley 802 and the rotating arm 803 rotate synchronously. When the left and right rotating arms 803 rotate, they drive the L-shaped plate 805 to maintain a horizontal state and move along a circular path. When the L-shaped plate 805 is at the highest point of the circular path, the L-shaped plate 805 lifts the aluminum profile above the belt conveyor 701. Subsequently, as the L-shaped plate 805 descends, it transfers the aluminum profile onto the surface of the belt conveyor 701.

[0045] A second pulley 806 is rotatably connected to the lower front side of the stand 801. The pulleys 802 and 806 on each stand 801 are connected by a drive belt 807. Through the transmission action of the drive belt 807, the second pulley 806 can drive the pulley 802 to rotate.

[0046] Please see Figure 8 The drive assembly 900 includes two sets of connecting shafts 901. The left connecting shaft 901 is rotatably connected to the three sets of uprights 801 on the left side, and the right connecting shaft 901 is rotatably connected to the three sets of uprights 801 on the right side. The connecting shaft 901 is also fixed at the center of the three sets of pulleys 806. Furthermore, the height of the connecting shaft 901 is lower than the lowest point of the L-shaped plate 805's movement path to avoid affecting the normal movement of the L-shaped plate 805.

[0047] Both sets of connecting shafts 2 901 have pulleys 3 902 fixedly mounted at their front ends. A pulley 4 903 is positioned between the two sets of pulleys 3 902. The two sets of pulleys 3 902 and pulley 4 903 are connected by a transmission belt 2 904. A motor 3 905 is fixedly mounted at the center of one set of pulleys 3 902. The installation of pulley 4 903 tightens the transmission belt 2 904, and through the transmission action of the transmission belt 2 904, the two sets of pulleys 3 902 rotate synchronously.

[0048] The unloading method of the unloading device in this aluminum profile coating production line is as follows:

[0049] S1. The aluminum profile is suspended on the hook 400 and moves with the suspension slide 200. After the aluminum profile is coated, it moves with the suspension slide 200 to the upper horizontal track 101 and moves from left to right. During this process, the aluminum profile is in a vertical state.

[0050] S2. As the aluminum profile moves from left to right along the upper horizontal track 101 with the suspension slide 200, the vertical aluminum profile abuts against the top of the lifting conveyor belt 500. The rotating roller 502 is driven to rotate by the motor 504, the annular belt 503 moves, the push rod 506 intervals the aluminum profile and pushes the aluminum profile to the right, so that one end of the aluminum profile is hung on the hook 400 and the other end abuts against the top of the annular belt 503. When the suspension slide 200 moves along the inclined track 102, the inclination angle of the aluminum profile gradually decreases until the aluminum profile is horizontal.

[0051] S3. When the aluminum profile moves to support the lower half of the conveyor belt 500, the aluminum profile adheres to the top of the first inclined section 6012 and the second inclined section 6022, and continues to move downward. After the aluminum profile separates from the conveyor belt 500, one end of the aluminum profile is hung on the hook 400, and its lower surface adheres to the third horizontal section 6031.

[0052] S4. The motor 3905 drives one of the pulleys 3902 to rotate, which, in conjunction with the transmission belt 2904, drives the other pulley 3902 to rotate. Thus, the two connecting shafts 2901 rotate synchronously, driving the pulley 2806 to rotate. In conjunction with the transmission belt 1807, the pulley 1802 and the rotating arm 803 rotate.

[0053] S5. By rotating synchronously with the two rotating arms 803 distributed on the left and right, the L-shaped plate 805 is lifted from the bottom of the aluminum profile along the arc path and transferred to the upper left end of the belt conveyor 701. During the upward movement of the aluminum profile, the aluminum profile is separated from the hook 400. Then the aluminum profile moves to the right with the belt conveyor 701 to complete the unloading.
