Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of suspension conveying line blanking device, and concretely relates to a hooking and unhooking device for suspension section bar. BACKGROUND

[0002] At present, the suspension conveying (or vertical conveying) mode can be selected in the conveying and surface spraying process of section bars, which suspends the section bar at one end through a hook under the conveying frame and conveys in this state. Taking the spraying process as an example, after the section bar is sprayed, the section bar in the suspended state needs to be converted into horizontal conveying. Before horizontal conveying, the conventional scheme is to separate the section bar from the hook by manual mode, which has low automation degree, high production cost, and great harm to the body of the workers due to the chemical substances in the environment caused by spraying. The existing automatic blanking technical scheme, such as the Chinese invention patent with the application publication number CN119262815A, gradually converts the section bar into horizontal placement in the conveying process through the transmission belt mode, and then moves the horizontally placed section bar through the transfer assembly to realize the process of taking the section bar off the hook in the moving process, wherein the action of the transfer assembly is relatively single, and the hook and the section bar may be stuck or unhooked due to the angle and position relationship between the hook and the section bar, and the workers still need to assist in completing the unhooking. The Chinese utility model patent with the authorization announcement number CN220033228U has the working mode of fixing the hooks one by one and then separating the section bars therefrom, and the working efficiency needs to be improved.

[0021] This utility model provides a hooking and unhooking device for suspended profiles, which solves the problem of low success rate or efficiency of existing unhooking methods, and realizes an automated and more efficient profile unhooking and unloading process.

[0022] Please see Figure 1 This utility model discloses a hook-and-unhook device for suspended profiles, wherein the profile 4 is suspended by a hook 3, or more specifically, generally suspended on a suspension conveyor frame 1. The present utility model aims to detach the hook 3 from the profile 4 by striking the hook 3. The hook-and-unhook device for suspended profiles includes a hooking device 5 and a return device 6. The hooking device 5 has a hooking part 51 for striking the hook 3, located on one side of the hook 3; the return device 6 has a top hook part 61 for limiting the swing amplitude of the hook 3, located on the side of the hook 3 opposite to the hooking part 51.

[0023] The hooking device 5 can push the hook 3 to one side (specifically, swing; the upper end of the hook 3 is generally always connected to the suspended conveyor frame 1 during operation), while the return device 6 on the other side acts as a limit to prevent the hook 3 from swinging too much. Furthermore, after the hook 3 swings and collides with the return device 6, it will rebound, turning towards the hooking device 5, allowing the hooking device 5 to push the hook 3 again. This can be repeated multiple times (multiple times in a short period of time), visually creating a high-frequency striking process that causes the hook 3 to vibrate repeatedly. Under these conditions, the hook below the hook 3 will disengage from the through hole on the profile 4 used for suspension, thus achieving automatic unhooking and unloading without manual intervention. This utility model can be applied to... Figure 3 The automatic unhooking system shown can also be applied to other existing automatic unhooking systems or conveyor lines.

[0024] More specifically, please see Figure 3 and Figure 1 , Figure 1 for Figure 3 The enlarged view of part A shows that the suspended conveyor frame 1 is equipped with several hooks 3 that can move along the suspended conveyor frame 1. A transverse conveyor frame 2 is located next to the suspended conveyor frame 1, forming a suspended transverse section above the transverse conveyor frame 2. The hooks 3 at the suspended transverse section are in a drooping state, with the lower end of the hook 3 bent upwards or diagonally upwards on the side facing the transverse conveyor frame 2. The lower hook of the hook 3 suspends one end of the profile 4 (the upper end when suspended), while the other end of the profile 4 (the lower end when suspended) contacts the side of the transverse conveyor frame 2 away from the suspended transverse section. The profile 4 is positioned inclined or horizontally on the transverse conveyor frame 2. The hooking and unhooking process of this invention is performed in this state. The process of converting vertical profiles to horizontal positions using a structure / method similar to the profile horizontal guide frame 8 is existing technology. The main improvement of this invention is that it replaces the manual unhooking in the existing technology with a hooking and unhooking device, or serves as a replacement or supplement to other mechanical devices / systems.

[0025] Please see Figure 1 In a preferred embodiment, the hooking device 5 includes a hooking guide frame 52, on which a hooking part 51 is slidably connected via a hooking linear guide assembly. The hooking part 51 or the hooking linear guide assembly is connected to a hooking drive mechanism. More specifically, the hooking drive mechanism includes a hooking motor, which is mounted on the hooking guide frame 52. The output end of the hooking motor is connected to a connecting rod and forms a crank-slider mechanism with the linear guide assembly to convert the continuous rotation of the hooking motor into the reciprocating linear movement of the hooking part 51. This structure can stably achieve the desired high-frequency striking effect. Preferably, the hooking part 51 is capable of reciprocating to continuously strike the hook 3 multiple times.

[0026] Preferably, the length direction of the hook linear guide assembly is fixed or adjustable and oriented diagonally downwards. Setting the hook direction to a downward tilt at a certain angle helps to push the hook 3 and also helps to cause vibration of the hook 3 in the length direction. Further, it also includes a main frame 50, which is fixedly mounted on the ground or otherwise fixed in position relative to the ground. The main frame 50 is used to install the hook device 5 (specifically, to install the hook guide frame 52), and preferably the installation angle is adjustable to allow the length direction of the hook linear guide assembly to be adjustable and oriented diagonally downwards. More specifically, the hook guide frame 52 is hinged to the main frame 50 at one end in the length direction of the hook linear guide assembly, and the other end of the hook guide frame 52 is connected to the main frame 50 via a height adjustment member 53. The height adjustment component 53 includes a height adjustment screw hinged to the hook guide frame 52. The main frame 50 has a height adjustment through hole, through which the height adjustment screw passes. Two limit nuts are threaded onto the height adjustment screw, and the two limit nuts are located on both sides of the height adjustment through hole.

[0027] Please see Figure 2 In a preferred embodiment, the return device 6 includes a return fixing frame 62, on which a return rotating arm 63 is rotatably connected. One end of the return rotating arm 63 protrudes towards the side near the hooking device 5 and has a hook portion 61 at its end. The return rotating arm 63 is also connected to a limit spring 64. More preferably, the limit spring 64 is located at the end of the return rotating arm 63 away from the hook portion 61, and the rotatable connection position between the return rotating arm 63 and the return fixing frame 62 is located between the limit spring 64 and the hook portion 61, forming a lever structure. The limit spring 64 is correspondingly a tension spring. Figure 2 The diagram shows the spring in its natural state. In reality, the end of the spring is connected to a hook on the upper end of the top-return rotating arm 63. The force exerted by the lever at both ends allows it to achieve equilibrium at the desired position, and provides the necessary cushioning and rebound after impact with the profile. More specifically, the top-return device 6 (specifically, the top-return fixing frame 62) is mounted on the main frame 50, and the end of the limiting spring 64 furthest from the top-return rotating arm 63 is also connected to the main frame 50. Compared to simply directly setting the top hook 61, the solution with the top-return rotating arm 63 and the limiting spring 64 provides more cushioning and rebound, making the unhooking process more favorable.

[0028] Preferably, the lateral dimension of the hook portion 51 is sufficient to cover at least two hooks 3 side by side, and / or, the lateral dimension of the top hook portion 61 is sufficient to cover at least two hooks 3 side by side. More preferably, the lateral dimensions of both the hook portion 51 and the top hook portion 61 are sufficient to cover at least two hooks 3 side by side. The hook portion 51 and the top hook portion 61 have a certain length, thereby enabling simultaneous operation of a row of hooks 3, further improving efficiency.

[0029] Preferably, the hook portion 51 has a hook pad on the side facing the hook 3, and / or the top hook portion 61 has a top hook pad on the side facing the hook 3. The hook pad and top hook pad are, for example, rubber or other soft or elastic materials, to avoid damage to the hook 3 and to avoid generating excessive noise.

[0030] Please see Figure 3 Preferably, the device further includes a top-feeding device 7, which includes a primary lifting mechanism 72 located at the bottom and a secondary lifting mechanism 73 connected to the upper part of the primary lifting mechanism 72. The upper part of the secondary lifting mechanism 73 has a top-feeding part 71. The primary lifting mechanism 72 can drive the secondary lifting mechanism 73 to lift and lower, and the secondary lifting mechanism 73 can drive the top-feeding part 71 to lift and lower. The two-stage lifting method makes the movement of the top-feeding part 71 complex and controllable. For example, it can quickly strike upwards several times and then strike again after a period of time; or first lift the profile to a certain height, and then slightly shake the profile by reciprocating swing; etc. It should be noted that in the prior art and some embodiments of this utility model, the top-feeding method used is only to push and lift the profile. In some cases, it can achieve unhooking, but there will still be failures, jamming, etc., and the success rate is difficult to guarantee. Therefore, the preferred solution is that the top-feeding part 71 can reciprocate to continuously strike the profile 4 times. Using this vibration-like method can effectively prevent structural jamming and further improve the unhooking success rate. The top section 71 has a certain length, and its size is larger than the width of a single profile along the width of the profile 4, thus enabling simultaneous operation of a row of profiles 4. Furthermore, the upper surface of the top section 71 preferably has a top pad, such as rubber or other soft or elastic material, to prevent damage to the profiles 4 and to avoid excessive noise. More preferably, the direction in which the top section 71 rises is fixed or adjustable, oriented diagonally upwards, which facilitates pushing the profiles and helps them disengage.

[0031] In summary, the hooking and unhooking device for suspended profiles of this utility model is equipped with a hooking device and a return device on both sides of the hook, which can cause the hook to vibrate, achieving a fast and highly successful unhooking process; and the unhooking process can be performed on multiple hooks in a row at the same time, thus saving a significant amount of time compared to unhooking them one by one.
