Description

Technical Field

[0001] This utility model belongs to the technical field of suspended conveyor feeding devices, specifically relating to a lifting and vibrating unhooking device for suspended profiles. Background Technology

[0002] Currently, in the processes of conveying and surface coating of profiles, a suspended conveyor (or vertical conveyor) method can be used. This involves suspending one end of the profile below a conveyor frame via a hook for transport. Taking coating as an example, after painting, the suspended profile needs to be transferred to a horizontal conveyor. Traditionally, before horizontal transport, the profile is manually detached from the hook. This method has low automation, high production costs, and the chemicals present in the coating environment pose significant health risks to workers. Existing automated unloading technologies, such as the Chinese invention patent application CN119262815A, use a conveyor belt to gradually transfer the profile to a horizontal position during transport. Then, a transfer component moves the horizontally placed profile, removing it from the hook during this movement. In existing solutions, the forces acting on the profiles during movement are usually simple and singular, and the expected movement path of the profiles is also relatively fixed. However, due to the unpredictable differences in angle and position of the profiles during actual automatic conveying, some profiles may fail to detach, resulting in a low success rate of automatic detachment. This still requires frequent assistance from staff to complete the detachment, affecting the efficiency of automated processing. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lifting and vibration unhooking device for suspended profiles, which solves the problems of the single effect of existing solutions on profiles and the low success rate of automatic unhooking of profiles, and realizes that various profiles can complete automatic unhooking more quickly and effectively through lifting and vibration.

[0004] According to the technical solution of this utility model, this utility model provides a lifting and vibration unhooking device for suspended profiles, including a primary lifting mechanism and a secondary lifting mechanism connected to the upper part of the primary lifting mechanism. The upper part of the secondary lifting mechanism has a top material part. The primary lifting mechanism can drive the secondary lifting mechanism to lift and lower, and the secondary lifting mechanism can drive the top material part to lift and lower.

[0005] Furthermore, the profile is placed horizontally or at an angle, with one end of the profile suspended on a hook, and the lifting and vibrating unhooking device for suspending the profile is located below the profile and close to the hook.

[0006] Furthermore, in the direction along the width of the profile, the size of the top section is greater than the width of a profile; and / or, the upper surface of the top section has a top pad.

[0007] Furthermore, the direction in which the top material rises is either fixed or adjustable, and is set to face diagonally upwards.

[0008] Furthermore, the secondary lifting mechanism includes a secondary lifting base, on which a secondary lifting motor is mounted. The output end of the secondary lifting motor is connected to two secondary lifting eccentric shafts. The two secondary lifting eccentric shafts are laterally distributed and can rotate synchronously. The eccentric portions at the ends of the two secondary lifting eccentric shafts are rotatably connected to the top material part. Moreover, the positions of the two rotatable connection points between the top material part and the two secondary lifting eccentric shafts, as well as the positions of the axial centers of the two secondary lifting eccentric shafts, constitute the four vertices of a parallelogram.

[0009] Furthermore, both secondary lifting eccentric shafts are rotatably connected to the secondary lifting base, and a synchronous gear set is rotatably connected to the secondary lifting base. The synchronous gear set includes a driving gear, an intermediate gear, and a driven gear of the same size that mesh in sequence. One of the two secondary lifting eccentric shafts is coaxially arranged with the driving gear, and the other is coaxially arranged with the driven gear. There is one secondary lifting motor, which is driven by the driving gear.

[0010] Furthermore, the primary lifting mechanism includes a primary lifting base, on which a primary lifting motor is mounted. The output end of the primary lifting motor is connected to a primary lifting eccentric shaft. The eccentric portion at the end of the primary lifting eccentric shaft is rotatably connected to the lower end of a vertical primary lifting support rod. The upper end of the primary lifting support rod is rotatably connected to a secondary lifting base. The secondary lifting base is also connected to a downwardly extending lifting guide column. A lifting guide sleeve is mounted on the primary lifting base. The lifting guide column and the lifting guide sleeve are slidably connected in a matching manner.

[0011] Furthermore, a device base is provided below the primary lifting base. One side of the primary lifting base is hinged to the device base, and the other side of the primary lifting base is adjustablely connected to the device base through a top material angle adjustment component.

[0012] Furthermore, the top material angle adjustment component includes a vertically arranged angle adjustment screw, the lower end of which is hinged to the device base. A strip hole is provided on the primary lifting base, and the upper end of the angle adjustment screw passes through the strip hole of the primary lifting base. Two angle positioning nuts are threaded onto the angle adjustment screw, and the two angle positioning nuts are located on the upper and lower sides of the strip hole of the primary lifting base, respectively.

[0013] Furthermore, the bottom of the device base is also equipped with a top material height adjustment component for adjusting the height position of the device base.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] The lifting and vibration unhooking device for suspended profiles of this utility model adopts a two-stage lifting method, which makes the movement of the top part 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 shake the profile slightly by reciprocating swing, etc. Compared with the solution that can only push and lift the profile, this solution can achieve this lifting and vibration method, which can effectively prevent the structure from getting stuck and significantly improve the success rate of automatic unhooking.

Detailed Implementation

[0022] This utility model provides a lifting and vibration unhooking device for suspended profiles, which solves the problems of the existing solutions having a single effect on profiles and a low success rate of automatic unhooking. It enables various profiles to complete automatic unhooking more quickly and effectively through lifting and vibration.

[0023] Please see Figures 1 to 3 This utility model discloses a lifting and vibration unhooking device for suspended profiles, comprising 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 material part 71. The primary lifting mechanism 72 can drive the secondary lifting mechanism 73 to lift, and the secondary lifting mechanism 73 can drive the top material part 71 to lift.

[0024] More specifically, the lifting and vibration unhooking device 7 of the suspended profile of this utility model can be applied to... Figure 4 The illustrated hook system, existing unhooking system, or other feasible unhooking systems are described. In a typical unhooking system, profile 4 is placed horizontally or at an angle, with one end of profile 4 suspended from hook 3. The lifting and vibrating unhooking device 7 for suspending the profile is located below profile 4 and close to hook 3. As a supplementary explanation, for suspended conveying, a through hole is pre-drilled at the end of profile 4, through which hook 3 suspends profile 4, thus conveying the profile in a suspended manner. During the automatic unhooking process of unloading, profile 4 is placed almost horizontally, and then appropriately lifted to release profile 4 from hook 3.

[0025] The two-stage lifting mechanism employed in this invention makes the movement of the top material section 71 complex yet controllable. For example, it can rapidly strike upwards several times, then pause for a period before striking again; or it can first lift the profile to a certain height, then slightly shake it through reciprocating oscillation; etc. It should be noted that in some embodiments, the top material section 71 only pushes and lifts the profile, which can achieve disengagement in some cases, but failures and jamming may still occur, making the success rate difficult to guarantee. Therefore, this solution preferably allows the top material section 71 to reciprocate and lift to continuously strike the profile multiple times. This vibration-like method can effectively prevent structural jamming and significantly improve the disengagement success rate.

[0026] The top section 71 may have a certain length. For example, preferably, the size of the top section 71 is larger than the width of one profile 4 in the direction along the width of the profile 4, so that a row of profiles 4 can be worked on simultaneously. Furthermore, the upper surface of the top section 71 preferably has a top pad, such as rubber or other soft or elastic material, to avoid damage to the profiles 4 and to avoid generating excessive noise. More preferably, the direction in which the top section 71 rises is fixed or adjustable to face obliquely upwards, which makes it easier to push the profiles and facilitates the disengagement of the profiles.

[0027] More specifically, in the preferred embodiment illustrated, the secondary lifting mechanism 73 includes a secondary lifting base 731, on which a secondary lifting motor is mounted. The output end of the secondary lifting motor is connected to two secondary lifting eccentric shafts 732. The two secondary lifting eccentric shafts 732 are laterally distributed and can rotate synchronously. The eccentric portions at the ends of both secondary lifting eccentric shafts 732 are rotatably connected to the top material part 71. Furthermore, the positions of the two rotatable connection points between the top material part 71 and the two secondary lifting eccentric shafts 732, as well as the axial center positions of the two secondary lifting eccentric shafts 732, constitute the four vertices of a parallelogram. This achieves the lifting of the top material part 71 driven by the motor rotation, enabling rapid and stable reciprocating lifting of the top material part 71, and also forming the aforementioned upward-facing lifting process, applying a lateral force to the profile 4. Please refer to [link to relevant documentation]. Figure 3 , Figure 4 The lifting and vibrating unhooking device 7 of the suspended profile has the same angle and placement. The lifting process of the top part 71 is actually achieved by clockwise circular motion. As a result, the profile 4 will be subjected to the rightward component force applied by the top part 71 (especially when the upper surface of the top part 71 has a top pad or other material that can give it a large coefficient of friction). Therefore, while pushing the profile 4 upward, it can also push the profile away from the hook 3, which is more conducive to unhooking. After unhooking, the profile 4 will continue to gradually move away from the hook 3 and will not be hooked on the hook 3 again.

[0028] For example, the two secondary lifting eccentric shafts 732 are rotatably connected to a secondary lifting base 731. A synchronous gear set 733 is also rotatably connected to the secondary lifting base 731. The synchronous gear set 733 includes a driving gear, an intermediate gear, and a driven gear of the same size that mesh sequentially. One of the two secondary lifting eccentric shafts 732 is coaxially arranged with the driving gear, and the other is coaxially arranged with the driven gear. There is one secondary lifting motor, which is driven by the driving gear. It is understood that in some feasible embodiments, two motors are used to control the two secondary lifting eccentric shafts 732 separately; however, in this preferred embodiment, one motor is used for synchronous drive, with one eccentric shaft as the driving shaft and the other as the driven shaft. This simplifies control, reduces costs, and ensures the consistency of the rotation of the two eccentric shafts.

[0029] Furthermore, the primary lifting mechanism 72 includes a primary lifting base 721, on which a primary lifting motor is mounted. The output end of the primary lifting motor is connected to a primary lifting eccentric shaft 722. The eccentric portion at the end of the primary lifting eccentric shaft 722 is rotatably connected to the lower end of a vertical primary lifting support rod 723. The upper end of the primary lifting support rod 723 is rotatably connected to a secondary lifting base 731. The secondary lifting base 731 is also connected to a downwardly extending lifting guide column 734. A lifting guide sleeve 724 is mounted on the primary lifting base 721, and the lifting guide column 734 and the lifting guide sleeve 724 are slidably connected in a matching manner. This forms a crank-slider mechanism, converting the rotation of the primary lifting motor into the reciprocating lifting of the secondary lifting base 731. To ensure stable lifting, it is preferable that the lifting guide column 734 and the lifting guide sleeve 724 are four sets located at the four corners of the secondary lifting base 731; the primary lifting motor drives the primary lifting eccentric shaft 722 through a chain and sprocket mechanism (the chain is hidden in the figure). Both ends of the primary lifting eccentric shaft 722 are eccentric parts, which in turn connect to two primary lifting support rods 723. The two primary lifting support rods 723 are located on both sides of the secondary lifting base 731.

[0030] Preferably, a device base 74 is provided below the primary lifting base 721. One side of the primary lifting base 721 is hinged to the device base 74, and the other side of the primary lifting base 721 is adjustablely connected to the device base 74 via a top material angle adjusting component 741. The top material angle adjusting component 741 includes, for example, a vertically arranged angle adjusting screw. The lower end of the angle adjusting screw is hinged to the device base 74. A slotted hole is provided on the primary lifting base 721, and the upper end of the angle adjusting screw passes through the slotted hole. Two angle positioning nuts are threaded onto the angle adjusting screw, and the two angle positioning nuts are located on the upper and lower sides of the slotted hole in the primary lifting base 721, respectively. To ensure stability, two sets of top material angle adjusting components 741 are preferably provided. This allows for adjustable tilt angles of the primary lifting base 721 and its overall structure above it, enabling lifting towards an upward angle. Furthermore, it is preferable that the tilt angle corresponds to the tilt angle of the profile 4 at this time, and that the upper surface of the top material part 71 is basically parallel to the bottom surface of the profile, which further enhances the material lifting effect.

[0031] Preferably, a top material height adjusting component 742 for adjusting the height of the device base 74 is also provided at the bottom of the device base 74. Its structure is similar to that of the top material angle adjusting component 741, except that since it is only for vertical lifting, the hole for inserting the screw can be a round hole. The bottom of the top material height adjusting component 742 is fixedly connected to the ground, thereby fixing the overall position of the suspension profile lifting vibration unhooking device 7. Therefore, the suspension profile lifting vibration unhooking device 7 with the preferred embodiment shown in the figure is more flexible in use and can be adjusted to the required height and angle according to the actual situation.
