Description

Technical Field

[0001] This invention belongs to the technical field of profile spraying and curing equipment, specifically relating to an automatic chain removal device and method after profile curing treatment. Background Technology

[0002] In current vertical powder or paint spraying processes for aluminum profiles, profiles coated with powder or paint are suspended vertically before entering a curing oven, where the coating is cured at high temperatures to form the desired surface structure. The curing oven contains a fan, and the circulation of hot air causes the profiles to sway, potentially leading to collisions between parallel profiles and between the profiles and the oven's internal structure, resulting in surface damage. Currently, before entering the curing oven, the lower ends of several suspended profiles are typically connected by chains with clamps to prevent excessive swaying. However, this necessitates manual removal of the chains after curing, resulting in low efficiency. Therefore, an automatic chain removal solution is needed to address this long-standing problem for aluminum profile manufacturers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an automatic chain removal device and method after profile curing treatment, which solves the problem that the existing technical solution requires manual chain removal and has low efficiency, realizes automatic chain removal through mechanical device, significantly improves efficiency, and can be applied to various profiles.

[0004] According to the technical solution of the present invention, the present invention provides an automatic chain removal device after profile curing treatment, including a lifting frame, the lifting frame being disposed on one side of the profile suspension conveyor line, the lifting frame being connected to a lifting moving frame capable of lifting and moving via a lifting component, the lifting moving frame being connected to a horizontal moving frame capable of moving via a translation component, and the horizontal moving frame being provided with a separation claw mechanism capable of extending and retracting in the direction toward the profile suspension conveyor line.

[0005] Furthermore, the lifting assembly includes a lifting guide rail, which is mounted on the lifting frame. A lifting slider is slidably connected to the lifting guide rail, and the lifting slider is connected to the lifting movable frame. A lifting rack is provided on the lifting frame. A lifting motor is provided on the lifting movable frame, and a gear is provided at the output end of the lifting motor and meshes with the lifting rack.

[0006] And / or, the translation component includes a translation guide rail, which is mounted on a translation frame, and a translation slider is slidably connected to the translation guide rail and connected to the lifting frame; the translation frame is provided with a translation rack; the lifting frame is provided with a translation motor, and the output end of the translation motor is provided with a gear that meshes with the translation rack.

[0007] Furthermore, the separation claw mechanism includes a separation claw mounting frame, on which a plurality of separation claws are spaced apart; the position and / or length of the separation claws are adjustable.

[0008] Furthermore, the separating claw mounting bracket is connected to a separating claw flipping shaft; the translational moving frame is provided with a flipping shaft bracket, which is rotatably connected to the separating claw flipping shaft; the separating claw flipping shaft is connected to a flipping drive motor;

[0009] Alternatively, the separation claw mounting bracket and the translational frame are slidably connected via a telescopic track assembly; the translational frame is equipped with a telescopic rotating shaft, which is connected to a telescopic drive motor, and the telescopic rotating shaft is drively connected to the separation claw mounting bracket.

[0010] According to some embodiments, a limiting anti-sway component is provided on the translational frame, and / or a gap detection mounting bracket is provided on the translational frame, and a gap detection sensor is provided on the gap detection mounting bracket.

[0011] According to some embodiments, the lifting frame is provided with a lifting position sensor for directly or indirectly sensing the height position of the separating claw mechanism; and / or, the lifting moving frame is provided with a profile position sensor for sensing the profile.

[0012] According to some embodiments, a chain conveyor belt is provided below the profile suspension conveyor line, and / or a rear chain hanging mechanism is provided on the downstream side of the lifting frame, and / or a front material measuring mechanism is provided on the upstream side of the lifting frame.

[0013] Furthermore, the rear chain hanging mechanism includes a chain hanging frame, a clamping mechanism, and a chain detection device. The clamping mechanism is connected to the chain hanging frame through a clamping lifting mechanism and / or a clamping translation mechanism. The clamping mechanism is located below the profile suspension conveyor line. The chain detection device is arranged adjacent to the clamping mechanism and is located on one side of the profile suspension conveyor line.

[0014] Alternatively, the rear chain hanging mechanism includes a chain hanging frame, on which a chain hanging plate is provided, and the height of the chain hanging plate is adjustable. The chain hanging plate has a nail plate portion, on which several chain hanging nails protrude toward the lifting frame side. The nail plate portion is located below the profile suspension conveyor line.

[0015] According to the technical solution of the present invention, the present invention also provides an automatic chain removal method after profile curing treatment, which adopts the automatic chain removal device after profile curing treatment of the present invention, and the lifting and moving frame is equipped with a profile position sensor for sensing the profile, which includes the following steps:

[0016] Step S1: Initially, the separating claw mechanism is in the retracted state and its position is lower than the lower end of the profile on the profile suspension conveyor line; the translational moving frame moves upstream on the profile suspension conveyor line.

[0017] Step S2: The lifting and moving frame moves up and down, and the lower end position of the profile on the profile suspension conveyor line is detected by the profile position sensor;

[0018] Step S3: Based on the detection results of the profile position sensor, the lifting moving frame rises and moves to above the lower end of the profile on the profile suspension conveyor line, so that the separating claw mechanism is above the chain clamped at the lower end of the profile.

[0019] In step S4, the separating claw mechanism moves downstream of the profile suspension conveyor line under the drive of the translational moving frame, and the moving speed is matched with the moving speed of the profile on the profile suspension conveyor line, so that the separating claw mechanism and the profile move synchronously in the horizontal direction.

[0020] In step S5, the separating claw mechanism switches from the retracted state to the extended state and extends into the gap position of the profile; during this process, the translational movement described in step S continues;

[0021] In step S6, the separating claw mechanism moves downward under the drive of the lifting and moving frame; during this process, as the separating claw mechanism moves downward relative to the profile, the separating claw mechanism pulls the chain clamped at the lower end of the profile downward, so that the chain is separated from the profile.

[0022] Step S7: The separating claw mechanism continues to move downwards, up and down, shake, or retract and extend to ensure that the chain is separated from the profile and from the separating claw mechanism.

[0023] In step S8, the separating claw mechanism switches from the extended state to the retracted state, returning to the initial state described in step S1, and this process is repeated.

[0024] Furthermore, for an embodiment with the preferred rear chain hanging mechanism of the present invention, the automatic chain removal method after profile curing further includes the following steps: when the chain detection device detects that a chain has moved to the position of the clamping mechanism, the clamping mechanism clamps the chain, then the clamping mechanism moves downward and / or reciprocates laterally to separate the chain from the profile, and then the clamping mechanism releases the chain and resets.

[0025] Compared with the prior art, the main beneficial technical effects of the present invention are as follows:

[0026] 1. The automatic chain removal device and method for profile curing treatment of the present invention solves a problem that has long been sought to be solved in the field. Through mechanical device, the chain clamped at the lower end of the profile is automatically removed without manual intervention during the conveying process, which significantly improves work efficiency and reduces the labor intensity of workers; and ensures that the mechanical structure will not scratch the surface of the profile during the chain removal process.

[0027] 2. The automatic chain removal device and method for profile curing of the present invention preferably has multiple sensors for more intelligent and automatic operation; for example, the profile position sensor can move up and down with the lifting frame, and sense the length of the profile in front during the process, so as to adopt a corresponding chain removal working scheme, thus automatically applicable to profiles of various lengths and helping to improve work efficiency and reduce energy consumption.

[0028] 3. The automatic chain removal device and method for profile curing of the present invention preferably includes a rear-end chain hanging mechanism, which can further ensure complete chain removal. If the chain is still attached to the profile, after the chain moves to the rear-end chain hanging mechanism, the lower end of the chain will be caught by the chain hanging plate, and then, as the profile continues to be conveyed, the chain will be pulled off the profile. Preferably, a chain conveyor belt can also be provided to automatically transport the removed chain, for example, back to the process where the chain was installed before curing, further forming an overall automated processing solution.

[0039] This invention provides an automatic chain removal device and method for profiles after curing treatment, solving the problem of low efficiency caused by the need for manual chain removal in existing technologies. It achieves automatic chain removal via mechanical devices, significantly improving efficiency and is applicable to various profiles. For example, the background section of Chinese invention patent application CN116493221A also mentions the above-mentioned problems. Figure 9 The accompanying drawings of the prior art are cited for reference, but the chain structure is not limited thereto. For example, another common structure is to have small clips on the chain and to clip them to the bottom of the profile.

[0040] Please see Figure 1 , Figure 2An embodiment of the present invention discloses an automatic chain removal device for profile curing treatment, comprising a lifting frame 1, which is disposed on one side of the profile suspension conveyor line; more specifically, the bottom of the lifting frame 1 is a base fixed to the ground; the lifting frame 1 is vertically arranged; the lifting frame 1 is disposed on the rear side of the profile suspension conveyor line (close to the wall). The lifting frame 1 is connected to a lifting movable frame 2 capable of lifting and lowering via a lifting assembly, and a horizontally movable frame 3 capable of horizontal movement is connected to the lifting movable frame 2 via a translation assembly. The horizontally movable frame 3 is provided with a separating claw mechanism 4 capable of extending and retracting in the direction toward the profile suspension conveyor line. Thus, the separating claw mechanism 4 can be vertically lifted and horizontally translated, and can also achieve oblique movement by simultaneously lifting and translating. The extension and retraction of the separating claw mechanism 4 should be interpreted broadly: after the separating claw extends, it can reach between the suspended profiles, thereby pulling off the chain as it moves downward; after the separating claw retracts, it will not contact the profiles and chain, facilitating the movement and reset of the lifting movable frame 2 and other mechanisms.

[0041] Please see Figure 2 , Figure 3 , Figure 4 In a specific embodiment, the lifting assembly includes a lifting guide rail 11, which is mounted on the lifting frame 1. For example, the lifting guide rail 11 is located on the front side of the lifting frame 1, vertically aligned with the lifting frame 1, and positioned within a sufficiently long height range. To ensure reliable lifting and structural stability, the lifting frame 1 preferably has two columns, each with a lifting guide rail 11. A crossbeam or similar reinforcement can be provided between the two columns to enhance structural strength. A drag chain is provided on one side of the lifting frame 1. A lifting slider is slidably connected to the lifting guide rail 11, and the lifting slider is connected to the lifting moving frame 2. The lifting frame 1 is equipped with a lifting rack 12, for example, located on the right side of the left column (or the inner side of the lifting frame 1). A lifting motor 21 is mounted on the lifting moving frame 2, and the output end of the lifting motor 21 has a gear that meshes with the lifting rack 12. Thus, the gear at the output end of the lifting motor 21 can travel on the lifting rack 12, thereby driving the lifting moving frame 2 and other structures on it to move up and down along the lifting guide rail 11.

[0042] The translation component includes a translation guide rail 31, which is mounted on the translation frame 3. For example, the translation guide rail 31 is positioned below the horizontal frame plate of the translation frame 3. Preferably, there are two parallel translation guide rails 31 to ensure the stability of the movement. A translation slider is slidably connected to the translation guide rail 31, and the translation slider is connected to the lifting frame 2. Specifically, for example, the lifting frame 2 has an inverted L-shaped plate structure, in which the vertical plate is slidably connected to the lifting frame 1, and the upper horizontal plate is used to support and slidably connect the translation frame 3. The translation frame 3 is provided with a translation rack 32, for example, positioned below the horizontal frame plate of the translation frame 3. The lifting frame 2 is provided with a translation motor 22, with the output end of the translation motor 22 facing upward. The output end of the translation motor 22 is provided with a gear that meshes with the translation rack 32. Thus, the gear at the output end of the translation motor 22 can drive the translation rack 32, thereby driving the translation frame 3 and other structures on it to move horizontally left and right along the translation guide rail 31.

[0043] It is understood that the above embodiments only provide a preferred solution, and the present invention is not limited thereto. For example, the lifting / moving mechanism can also be a lead screw mechanism, a pulley mechanism, a telescopic cylinder mechanism, etc. Any method that can achieve controllable driving motion is acceptable.

[0044] In a preferred embodiment, the separating claw mechanism 4 includes a separating claw mounting frame 41, on which a plurality of separating claws 42 are spaced apart. The position and / or length of the separating claws 42 are adjustable, thereby facilitating installation and adjustment so that the spacing of the separating claws 42 matches the spacing of the profiles suspended by the profile suspension conveyor line. Specifically, for example... Figure 4 As shown, the separation claw mounting bracket 41 is flat and has a slotted hole. The separation claw 42 is connected to the slotted hole of the separation claw mounting bracket 41 by bolts, allowing the installation position of the separation claw 42 to be adjusted within the slotted hole. And / or, as... Figure 5 As shown, the separating claw 42 is an adjustable and telescopic structure, comprising a rear sleeve and a front claw head. The claw head is fitted inside the sleeve, and the claw head is connected to the sleeve by bolts. Therefore, the total length of the separating claw 42 can be adjusted by adjusting the distance the claw head extends beyond the sleeve. The end (free end) of the separating claw 42 has a downward-facing bend or groove to form a claw / hook structure, ensuring a more stable hook onto the chain.

[0045] Please see Figure 3 , Figure 4In one embodiment of the present invention, the extension and retraction of the separating claw are achieved by flipping. A separating claw mounting bracket 41 is connected to a separating claw flipping shaft 43, which is, for example, fixed to the bottom of the plate-shaped separating claw mounting bracket 41 via connecting plates at both ends. A flipping shaft bracket 33 is provided on the translational frame 3, and the flipping shaft bracket 33 is rotatably connected to the separating claw flipping shaft 43; the flipping shaft bracket 33 is preferably, for example, a bearing bracket, and is sleeved and connected to the separating claw flipping shaft 43 via bearings. A flipping drive motor 44 is connected to the separating claw flipping shaft 43, which is, for example, fixedly mounted on a mounting plate on the upper side of the translational frame 3. Therefore, when the separating claw mechanism 4 is retracted, the separating claw 42 and the separating claw mounting bracket 41 are vertical and close to the lifting frame 1; when the separating claw mechanism 4 is extended, the flip drive motor 44 drives the angle of the separating claw flip shaft 43 to be different from that in the retracted state by, for example, 90°, so that the separating claw 42 and the separating claw mounting bracket 41 are horizontal, and the separating claw 42 protrudes forward from the front side of the translational moving frame 3 and the lifting moving frame 2 and other components.

[0046] Alternatively, please see Figure 5 , Figure 6 In another embodiment of the invention, the extension and retraction of the separating claw are achieved through telescopic movement. The separating claw mounting bracket 41 and the translational moving bracket 3 are slidably connected via a telescopic track assembly 34 (including a slide rail and a slider). The translational moving bracket 3 is provided with a telescopic rotation shaft 45, which is connected to a telescopic drive motor 46. The telescopic drive motor 46 is, for example, fixedly mounted on a mounting plate on the upper side of the translational moving bracket 3. The telescopic rotation shaft 45 is drively connected to the separating claw mounting bracket 41 to convert the rotation of the telescopic rotation shaft 45 into the translation of the separating claw mounting bracket 41. Specifically, for example... Figure 6 As shown, a pulley assembly is provided on the mounting plate on the upper side of the translational frame 3. One drive pulley in the pulley assembly is fixedly mounted coaxially with the telescopic rotating shaft 45. Two driven pulleys in the pulley assembly are horizontally distributed. A transmission belt is connected to the pulley assembly, thereby forming a horizontal transmission belt between the two driven pulleys, which is parallel to the telescopic track assembly 34. One point of the belt is fixedly mounted to the separation claw mounting frame 41. As the telescopic rotating shaft 45 and the drive pulley rotate, the transmission belt between the two driven pulleys will drive the separation claw mounting frame 41 to move horizontally back and forth.

[0047] It is understood that the above embodiments only provide two preferred solutions, and the present invention is not limited thereto. For example, a lead screw mechanism, a gear and rack mechanism, a telescopic cylinder mechanism, etc. can also be selected to realize the extension and retraction of the separating claw. Any method that can achieve controllable driving motion is acceptable.

[0048] like Figure 2 , Figure 4In the preferred embodiment shown, a limiting anti-sway component 5 is provided on the translational frame 3. The limiting anti-sway component 5 is used to limit the suspended profile. When the profile swings, the limiting anti-sway component 5 can support and block the profile, limiting the swing amplitude of the profile to a small range, preventing the profile from swinging too much and colliding with the mechanical structure. The limiting anti-sway component 5 is, for example, an inclined / bent plate / cover-like structure located above the separating claw mechanism 4. The front end face of the limiting anti-sway component 5 is horizontally flush. When a row of profiles rests against the front end face of the limiting anti-sway component 5, the row of profiles is basically flush, and the profiles are nearly vertical (in a natural, ideal vertical state, the profiles do not contact the limiting anti-sway component 5). The front end face of the limiting anti-sway component 5 slightly protrudes from the lifting moving frame 2, the translating moving frame 3, etc., so that when the separating claw mechanism 4 is in the retracted state, the foremost part that can contact the profile is the front end face of the limiting anti-sway component 5. When the separating claw mechanism 4 is in the extended state, the separating claw 42 protrudes from the front end face of the limiting anti-sway component 5. Optionally, such as... Figure 5 As shown, the translational frame 3 also has a baffle on the front side, and the baffle is provided with a clearance hole or clearance groove for the separation claw 42. The baffle can also be configured to serve as a limiting anti-sway component 5.

[0049] like Figure 4 In the preferred embodiment shown, a gap detection mounting bracket 35 is provided on the translational frame 3, and a gap detection sensor (not shown in the figure) is provided on the gap detection mounting bracket 35. The gap detection sensor is used to ensure that the separating claw 42 is located in the gap position between the profiles when it extends by detecting whether there are profiles in front of it. For example, multiple gap detection sensors are provided at the positions corresponding to the separating claw 42 / corresponding to the gap positions of the separating claw 42, or only one is provided as a reference when the spacing of the separating claws 42 is the same.

[0050] like Figure 1 In the preferred embodiment shown, the lifting frame 1 is provided with a lifting position sensor 13 for directly or indirectly sensing the height position of the separating claw mechanism 4. For example, the lifting position sensor 13 is located on the side of the lifting frame 1, with at least two sensors located at the highest and lowest lifting positions. The object sensed by the lifting position sensor 13 is, for example, a detection plate protruding on that side. The detection plate is, for example, located on the lifting moving frame 2, thereby indirectly sensing the height position of the separating claw mechanism 4 and avoiding the loss of control over its lifting movement range.

[0051] like Figure 3In the preferred embodiment shown, the lifting frame 2 is provided with a profile position sensor 23 for sensing profiles. The profile position sensor 23 is located below the separating claw mechanism 4 and is used to detect whether there is a profile in front when the lifting frame 2 moves up and down. When no profile is detected at the height position during the downward movement, it means that the lower end of the profile has been reached. In this way, the approximate position of the lower end of the profile is determined, which is also the approximate position of the chain.

[0052] It is conceivable that the aforementioned sensors, such as infrared sensors, can be used, and the sensor's setting method and position can be selected as needed. For example, the profile position sensor 23 and the gap detection sensor can coexist as needed; or in some embodiments, the profile position sensor 23 is also configured to detect profile gaps to ensure that the separating claw 42 is located in the gap between the profiles when it extends, thus eliminating the need for the gap detection mounting bracket 35 and the gap detection sensor. Furthermore, in the case where no sensor is set, the corresponding functions can be implemented, for example, through direct input program control, but this may lack in terms of intelligence and automation. For example, it cannot adapt to profiles of different lengths, or it needs to move a sufficiently large height distance each time to ensure that profiles of various lengths can be used, which will lead to increased lifting and lowering distance, reduced work efficiency, and increased energy consumption.

[0053] In some preferred embodiments, a chain conveyor belt (not shown in the figure) is provided directly below the profile suspension conveyor line. The unloaded chain will fall onto the chain conveyor belt and can then be automatically transported away, for example, back to the process where the chain was installed before curing, further forming an overall automated processing solution.

[0054] In some preferred embodiments, such as Figure 1 As shown, a front-end length measuring mechanism 7 is provided on the upstream side of the lifting frame 1. The function of the front-end length measuring mechanism 7 is to measure the length of the profile before it is conveyed to the lifting frame 1, thereby providing a reference for the chain removal operation and helping to accelerate the real-time design calculation and control of the actions of the separation claw mechanism and other parts. The front-end length measuring mechanism 7 can adopt any method that can realize length measurement; preferably, the front-end length measuring mechanism 7 is a grating ruler, which is vertically set and located on both sides of the profile suspension conveyor line.

[0055] like Figure 1 , Figure 2 As shown, a rear-end chain hanging mechanism is provided on the downstream side of the lifting frame 1. Please also refer to... Figure 7Preferably, the rear chain hanging mechanism includes a chain hanging frame 6, on which a chain hanging plate 621 is provided, and the height of the chain hanging plate 621 is adjustable. The chain hanging plate 621 has a nail plate portion 622, and the nail plate portion 622 has a plurality of chain hanging nails 623 protruding towards the side of the lifting frame 1; for example, the chain hanging plate 621 may have a plurality of holes and bolts installed to form the nail plate portion 622. The nail plate portion 622 is located directly below the profile suspension conveyor line, so that if the chain is still attached to a profile with a clamp, after the chain moves to the rear chain hanging mechanism, the chain links will be caught by the nail plate portion 622 of the chain hanging plate 621, and then as the profile continues to be conveyed, the chain will be pulled off the profile, thus ensuring complete removal of the chain.

[0056] The height position of the chain plate 621 is adjustable, for example... Figure 7 As shown, the assembly includes an adjusting screw 624, an adjusting motor 625, and a limiting slide 626. The adjusting screw 624 and the limiting slide 626 are arranged vertically side by side. The adjusting screw 624 is rotatably connected to the upper and lower ends of the chain hanging frame 6, for example, via bearing brackets. A threaded sleeve, such as a nut, is fixedly connected to the back side of the chain hanging plate 621 and is threadedly connected to the screw 624. The output end of the adjusting motor 625 is connected to the adjusting screw 624. The limiting slide 626 acts as a guide rail and is slidably connected to the back side of the chain hanging plate 621. Thus, the chain hanging plate 621 is basically unable to rotate and can only be raised and lowered under the threaded action of the screw mechanism. With this configuration, the height of the chain hanging plate 621 can be automatically adjusted by the motor to suit profiles of different lengths, ensuring that the chain hanging plate 621 is located below the profile without being too far from the bottom of the profile, which would result in the chain not being able to be hooked or the chain pulling effect being poor.

[0057] Please see Figure 8 In another preferred embodiment of the present invention, with Figure 7Unlike the structure shown, the rear chain hanging mechanism includes a chain hanging frame 6, a clamping mechanism 611, and a chain detection device 612. The clamping mechanism 611 is located below the profile suspension conveyor line, so that the lower end of the profile on the suspension conveyor line is above the clamping mechanism 611. When, after the aforementioned structure, some profiles still have chains that have not completely detached, the remaining part of the chain hangs drooping from the lower end of that individual profile. The drooping chain can enter the clamping mechanism 611, and the clamping mechanism 611 can clamp the chain through its movement. The clamping mechanism 611 is connected to the chain hanging frame 6 via a clamping lifting mechanism 613 and / or a clamping translation mechanism 614, thereby enabling lifting and / or translation, and thus pulling the chain that has not yet detached from the profile. The chain detection device 612 is arranged adjacent to the clamping mechanism 611, and the chain detection device 612 is located on one side (e.g., the rear side) of the profile suspension conveyor line. In other words, the chain detection device 612 is located near the clamping mechanism 611. The chain detection device 612 does not obstruct the profile and chain, and can accurately detect whether the chain has entered or is about to enter the clamping mechanism 611. The chain detection device 612 is, for example, a lidar or other photoelectric detection switch / sensor. The chain detection device 612 is connected to the control system of the rear chain hanging mechanism or directly connected to the clamping mechanism 611 to transmit signals and realize the required action process.

[0058] More specifically, such as Figure 8 As shown, the clamping mechanism 611 includes a transverse clamping mechanism base plate, on which a slide rail slider assembly is provided, including two sliders, each with a protruding clamping bar 615. The slide rail slider assembly also has a driving device, which can drive the two clamping bars 615 to move towards each other (clamping the chain) and away from each other (releasing the chain). Based on the existing technology, this driving device is easy to implement. For example, the slide rail slider assembly itself can adopt an existing "linear guide bidirectional positive and negative tooth" type slide table product with this function, or the two sliders can be controlled by a pneumatic cylinder / electric cylinder, etc., which will not be elaborated here.

[0059] It is worth noting that in the preferred embodiment of the present invention, the clamping rod 615 is conical in shape, gradually tapering from the fixed end to the free end, and both clamping rods 615 are inclined downwards relative to the horizontal direction. With this structure, after the chain is released, it easily falls off under gravity and separates from the clamping rods 615, without remaining on the clamping mechanism 611 and affecting subsequent operations. Furthermore, the upper part of the clamping mechanism 611 has an inclined baffle plate, which can block the sliding block and other driving structures of the clamping mechanism 611, leaving only the clamping rods 615 exposed, preventing the chain from entering the driving structure of the clamping mechanism 611 and causing jamming.

[0060] Clamping lifting mechanism 613, for example, is the same as described above. Figure 7 In the embodiment, the height-adjustable structure is similar. The chain support 6 has parallel vertical adjusting screws 624 and limiting slide pins 626. The adjusting screws 624 and the upper and lower ends of the chain support 6 are rotatably connected, for example, via bearing brackets. A threaded sleeve, such as a nut, is fixedly connected to the back side of the clamping mechanism 611 (the clamping mechanism base plate), and is threadedly connected to the adjusting screws 624. The driving part of the clamping lifting mechanism 613 is a motor (adjusting motor 625). The output end of the adjusting motor 625 is connected to the screws 624. The limiting slide pin 626 acts as a guide rail, slidingly connected to the back side of the clamping mechanism 611 (the clamping mechanism base plate). Thus, the clamping mechanism 611 can move vertically under the drive of the motor of the clamping lifting mechanism 613.

[0061] The clamping translational mechanism 614 is, for example, a clamping translational cylinder. The clamping mechanism base plate of the clamping mechanism 611 consists of two stacked layers that slide against each other. The bottom base plate is directly connected to the clamping lifting mechanism 613 to achieve overall lifting. The clamping translational cylinder is fixedly installed on the bottom base plate, and the piston rod of the clamping translational cylinder is connected to the upper base plate, thereby driving the clamping rod 615 to move laterally. Through lateral translation or repeated shaking, the chain can also be detached from the profile. Preferably, both the clamping lifting mechanism 613 and the clamping translational mechanism 614 are present. After the clamping rod 615 clamps the chain, it moves downward while shaking left and right, resulting in higher chain pulling efficiency. After pulling off the chain, the left and right shaking can make the chain fall off faster. It is understood that the above mechanical structure can be replaced in various ways based on existing technology. The present invention is not limited to the specific structure described above. The focus is on achieving the required action process and effect.

[0062] Based on the above-described solution of the present invention, the present invention provides an automatic chain removal method after profile curing treatment. The following description focuses only on a preferred embodiment where the lifting frame 2 is equipped with a profile position sensor 23 for sensing the profile, to demonstrate the superior effect of the present invention. It is understood that control can be achieved through other means even without a sensor, as explained above. It is also understood that the state of this device during use, such as... Figure 1 The device shown has a front end with a... Figure 9 The profile overhead conveyor shown ( Figure 9 The rear of the profile suspension conveyor shown is the side wall of the curing oven. After the profile exits the curing oven, the rear of the profile suspension conveyor is this device, thus forming... Figure 10 The state shown.

[0063] The preferred method includes the following steps:

[0064] Step S1, the initial state (for ease of description, the state that has just completed one chain pulling action is called the initial state) is that the separating claw mechanism 4 is in the retracted state and its position is lower than the lower end of the profile on the profile suspension conveyor line; the translation moving frame 3 is translated (reset) upstream of the profile suspension conveyor line.

[0065] Step S2, the lifting and moving frame 2 moves up and down, and the lower end position of the profile on the profile suspension conveyor line is detected by the profile position sensor 23;

[0066] In step S3, based on the detection result of the profile position sensor 23, the lifting moving frame 2 moves upward to above the lower end of the profile on the profile suspension conveyor line, with a sufficient distance from the lower end of the profile, so that the separating claw mechanism 4 is located above the chain clamped at the lower end of the profile; and the separating claw 42 of the separating claw mechanism 4 is located in the gap between the profiles (ensuring this through the profile position sensor 23 or the gap detection sensor).

[0067] It should be noted that the actions in steps S1, S2, and S3 above can be performed step by step or simultaneously. They are described separately in this article only for the sake of ease of expression and understanding.

[0068] In step S4, the separating claw mechanism 4 moves downstream of the profile suspension conveyor line under the drive of the translational moving frame 3, and the moving speed is adapted to the moving speed of the profile on the profile suspension conveyor line, so that the separating claw mechanism 4 (the separating claw 42) and the profile (the gap position) move synchronously in the horizontal direction; this synchronous movement process is set to be consistent with the profile suspension conveyor line, or is monitored in real time by the profile position sensor 23 or the gap detection sensor.

[0069] In step S5, the separating claw mechanism 4 switches from the retracted state (e.g., gradually) to the extended state, extending into the gap position of the profile; during this process, the translational movement described in step S4 continues;

[0070] Step S6, the separating claw mechanism 4 moves downward under the drive of the lifting moving frame 2; (optionally, during this process, the translational movement described in step S4 continues;) During this process, as the separating claw mechanism 4 moves downward relative to the profile, the separating claw mechanism 4 pulls the chain clamped at the lower end of the profile downward, so that the clamp gradually separates from the profile, thereby realizing the separation of the chain from the profile.

[0071] It should be noted that, in steps S5 to S6 above, the separating claw 42 moves downwards while simultaneously moving downstream in sync with the profile (e.g., ...). Figure 1The separation claw 42 moves to the right side (in the middle) to ensure that it does not scratch the surface of the profile. In step S6 (when the separation claw mechanism 4 pulls the chain downward), it can also move asynchronously, but only downward, or move slowly and short distance in the opposite direction relative to the profile, so that the separation claw 42 is closer to the clamp of the chain, which helps to remove the chain at once and avoids the clamps remaining on the profile. Of course, this process will cause a small swing of the profile and surface friction, but it will not affect the quality of the profile.

[0072] Step S7: The separating claw mechanism 4 continues to move downwards or up and down or extends and retracts to ensure that the chain is separated from the profile and the chain is separated from the separating claw mechanism 4.

[0073] In step S8, the separating claw mechanism 4 switches from the extended state to the retracted state, returning to the initial state described in step S1, and this process is repeated.

[0074] Further for those with Figure 8 The preferred embodiment of the rear chain hanging mechanism shown further includes the following steps: (in the case where the separation claw mechanism 4 fails to remove all the clamps) When the chain detection device 612 detects that a chain has moved to the position of the clamping mechanism 611 (e.g., between the two clamping bars 615), the clamping mechanism 611 clamps the chain, and then the clamping mechanism 611 moves downward and / or reciprocates laterally to separate the chain from the profile, and then the clamping mechanism 611 releases the chain and resets.

[0075] In summary, this solution addresses a long-standing problem in this field. Compared to traditional manual operation, this solution uses a mechanical device to automatically disassemble the chain clamped at the lower end of the profile during transport, significantly improving work efficiency and reducing the labor intensity of workers. Furthermore, the mechanical structure ensures that the disassembly process does not scratch the profile surface. Compared to the existing patent CN116493221A, which designs a novel curing device and process to avoid the chain installation, this solution takes a different approach, designing a device to replace manual chain disassembly. It is conceivable that this solution can utilize existing mature curing ovens and their processes, thus ensuring consistent and relatively stable curing results. Simply adding this solution's device after an existing curing oven makes it even easier to apply.
