Description

Technical Field

[0001] The present invention belongs to the technical field of profile processing and conveying equipment, and particularly relates to a decoupling system for suspended profiles. Background Art

[0002] At present, during the processes of conveying profiles and surface spraying treatment, etc., a suspended conveying (or vertical conveying) method can be optionally adopted, that is, one end of the profile is hung under a conveying rack through a hook, and the profile is conveyed in this state. Taking the spraying treatment as an example, after the profile is sprayed with paint, it is necessary to convert the suspended profile to horizontal conveying. Before horizontal conveying, the traditional solution is to manually detach the profile from the hook. This method has low automation, high production costs, and the chemical substances present in the environment due to spraying pose a great harm to the health of the staff.

[0027] The present invention provides a decoupling system for suspended profiles, which solves the problems such as low efficiency of existing decoupling methods, realizes an automated and efficient decoupling and blanking process, and ensures the success rate of automatic decoupling.

[0028] Please refer to Figures 1 to 4 , a decoupling system for suspended profiles of the present invention includes a suspended conveyor rack 1 and a transverse conveyor rack 2. A plurality of hooks 3 capable of moving along the suspended conveyor rack 1 are arranged on the suspended conveyor rack 1. The hooks 3 are used for hanging profiles 4. Specifically, through holes are pre-opened at the ends of the profiles 4, and then the hooks hang the profiles through these through holes, so as to convey the profiles in a suspended manner. The upstream side of the suspended conveyor rack 1 passes through, for example, a surface treatment device, so as to perform surface treatment during the conveying of the suspended profiles; or, for example, the suspended conveyor rack 1 is a section of conveyor line adopted to save space, improve efficiency and conveying quality; furthermore, the suspended conveyor rack 1 can be selected as, for example, a circular conveyor line, or end at the end of the subsequent suspended transverse section 10 described below; the hooks 3 generally move on the suspended conveyor rack 1 at a set speed and in a set manner under the drive of a drive mechanism. The transverse conveyor rack 2 is a relatively conventional conveyor rack, generally horizontal. Different from suspension, the profiles are placed horizontally on it. The transverse conveyor rack 2 is, for example, a belt conveyor, so as to be able to move the profiles; or, according to the actual needs of different applications, the transverse conveyor rack 2 can also be selected as other placement racks, and subsequent operations such as manual inspection, packaging, and transfer of the profiles can be performed, etc. It can be understood that the focus of the present invention lies in the decoupling process, and the structures of the suspended conveyor rack 1 and the transverse conveyor rack 2 do not need to be particularly limited, including but not limited to the structures and types listed in this article.

[0029] The suspended conveyor rack 1 forms a suspended transverse section 10 above the transverse conveyor rack 2. The suspended transverse section 10 is generally horizontal, or can also be selected to form a small certain angle with the horizontal plane. The hooks 3 at the suspended transverse section 10 are in a hanging state, for example, in a natural hanging state, and the hanging state is basically a vertical state. At the suspended transverse section 10, the lower end of the hook 3 is a lower hook portion that bends upward or obliquely upward on the side facing the transverse conveyor rack 2. The lower end (lower hook portion) of the hook 3 is hung and connected to one end (the upper end during suspension) of the profile 4. The other end (the lower end during suspension) of the profile 4 contacts the side of the transverse conveyor rack 2 away from the suspended transverse section 10. The profile 4 is inclined or horizontal on the transverse conveyor rack 2; generally, at this time, the end of the profile 4 close to the hook 3 is relatively higher and slightly inclined with respect to the horizontal plane.

[0030] A hook engaging device 5 and a pushing-back device 6 are also provided at the suspended horizontal section 10. Specifically, it includes a hook disengaging system frame having a column structure, and the hook engaging device 5 and the pushing-back device 6 are arranged on the hook disengaging system frame; the hook engaging device 5 and the pushing-back device 6 are both located, for example, at the middle position in the length direction of the hook 3. The hook engaging device 5 has a hook engaging part 51 for hitting or pushing the hook 3, and the hook engaging part 51 is located on the side of the hook 3 facing the transverse conveyor 2. The pushing-back device 6 has a hook pushing part 61 for restricting the swinging amplitude of the hook 3, and the hook pushing part 61 is located on the side of the hook 3 opposite to the hook engaging part 51.

[0031] A pusher device 7 is further included. The pusher device 7 is located below the profile 4 suspended at the suspended horizontal section 10, and the pusher device 7 has a pusher part 71 for hitting or pushing the profile 4 upward or obliquely upward. The pusher part 71 is located on the side of the profile 4 close to the hook 3; more specifically, the pusher part 71 is located between the midpoint in the length direction of the profile 4 and the hook 3, and generally closer to the hook 3, so that one end of the profile 4 close to the hook 3 can be lifted under the action of the pusher part 71, while the other end of the profile 4 is basically always in contact with the transverse conveyor 2.

[0032] The hook engaging device 5, the pushing-back device 6, and the pusher device 7 can work in cooperation, for example, to achieve the following process. The hook engaging device 5 pushes the hook 3 to move (specifically, swing) to the side opposite to the downward hook part (the upper end of the hook 3 is generally always connected to the suspended conveyor 1 during operation), and the pushing-back device 6 plays a limiting role on the other side to prevent the hook 3 from swinging too much; and, after the hook 3 swings and collides with the pushing-back device 6, it will rebound, that is, turn to move towards the hook engaging device 5, so that the hook engaging device 5 can push the hook 3 again, and this can be repeated many times. For example, intuitively, a high-frequency hitting process is formed, causing the hook 3 to vibrate repeatedly; at the same time, the pusher device 7 lifts the profile 4 or also forms vibration by quickly hitting. Refer to Figure 3 ., under the above actions, the lower hook part of the hook 3 will be disengaged from the through hole for suspension on the profile 4. After disengagement, the profile 4 is no longer under the traction of the hook 3, and will gradually move away from the hook 3 due to at least one of the actions of the pusher device 7, the inclination of the profile 4 itself, the vibration of the profile 4 itself, the collision between the end of the profile 4 and the hook 3, etc., so it will not be hooked on the hook 3 again; even if the disengagement fails once, as the above process is repeated many times (it can be repeated many times in a short time), the success rate of disengagement will tend to 100%. Therefore, after design and testing, by setting the frequencies, amplitudes, and times of the actions of the hook engaging device 5, the pushing-back device 6, and the pusher device 7, automatic disengagement and blanking can be achieved without manual intervention.

[0033] More specifically, on the upstream side of the horizontal conveyor frame 2, the suspension conveyor frame 1 is inclined and gradually decreases in height from the upstream side to the downstream side; and then it transitions to a suspended horizontal section 10 through a transition section. There is also a profile horizontal placement guide frame 8 which is inclined. The higher end of the profile horizontal placement guide frame 8 is located below the upstream side of the suspension conveyor frame 1 far from the horizontal conveyor frame 2, and the vertical projection of the profile horizontal placement guide frame 8 intersects with the vertical projection of the suspension conveyor frame 1. The profile horizontal placement guide frame 8 extends towards the horizontal conveyor frame 2 and gradually deviates from the suspension conveyor frame 1. The lower end of the profile horizontal placement guide frame 8 is close to or lower than the upper surface of the horizontal conveyor frame 2. The above content can be combined with Figure 2 , Figure 4 to understand more intuitively. Among them, the dotted line is the approximate position of the upstream side of the suspension conveyor frame 1. During the process of the profile 4 suspended below the suspension conveyor frame 1 being conveyed along the suspension conveyor frame 1, at the intersection point of the vertical projections shown in Figure 4 , another point on the profile 4 below the suspension point will contact the profile horizontal placement guide frame 8, and then as the conveying progresses, the other end of the profile 4 will slide along the profile horizontal placement guide frame 8, so that it gradually changes from an upright state to a horizontal state.

[0034] Further preferably, an auxiliary conveyor belt 81 is connected to the lower end of the profile horizontal placement guide frame 8, or rather, the auxiliary conveyor belt 81 is the structure of the lower end of the profile horizontal placement guide frame 8. In the illustrated embodiment, for the convenience of description, the profile horizontal placement guide frame 8 is described as a separate component. It can be selected as a rod (or pipe, plate, etc.) with a square cross-section, and its upper surface is inclined according to the inclination of the profile 4 at this stage. The profile 4 can slide on the upper surface of the profile horizontal placement guide frame 8, preferably in a closely fitting manner. The auxiliary conveyor belt 81 is inclined, and the higher end of the auxiliary conveyor belt 81 is higher than the upper surface of the horizontal conveyor frame 2. The connection between the profile horizontal placement guide frame 8 and the auxiliary conveyor belt 81 means that the profile 4 can smoothly complete the movement handover process from the former to the latter. For example, similar to the relationship between the aforementioned suspension conveyor frame 1 and the profile horizontal placement guide frame 8, there is also a situation where the profile horizontal placement guide frame 8 and the auxiliary conveyor belt 81 intersect in projection (for example, they intersect along the length direction of the profile), so that the profile can be transferred to be supported by the auxiliary conveyor belt 81; and then the auxiliary conveyor belt 81 is inclined downward, and the lower end is lower than the horizontal conveyor frame 2. By driving the end of the profile 4 to move, it is ensured that the profile 4 can finally be completely moved onto the horizontal conveyor frame 2. This combination method of the profile horizontal placement guide frame 8 in the form of a rod and the auxiliary conveyor belt 81 is relatively flexible and easy to implement in application, and has a low cost.

[0035] Please refer to Figure 5, More preferably, both ends of the auxiliary conveyor belt 81 are set to be height-adjustable, and the angle between the upper surface of the auxiliary conveyor belt 81 and the horizontal plane is set to be adjustable. Specifically, for example, the auxiliary conveyor belt 81 includes an auxiliary conveyor belt body 811 and an auxiliary conveyor belt frame 812. The auxiliary conveyor belt body 811 is a belt conveyor structure, including a driving wheel connected to a driving device (such as a motor), a driven wheel on the other side, and a conveyor belt body (the conveyor belt body is hidden in the figure) drivingly connected between the driving wheel and the driven wheel, so as to realize the belt conveying function. The lower end of the auxiliary conveyor belt 81 is hinged to a corresponding position of the auxiliary conveyor belt frame 812, and the higher end of the auxiliary conveyor belt body 811 is hinged with a conveyor belt first angle adjusting member 813, and then the lower end of the first angle adjusting member 813 is adjustably connected to a corresponding position of the auxiliary conveyor belt frame 812; the first angle adjusting member 813 is specifically a screw rod, and the auxiliary conveyor belt frame 812 has a strip-shaped hole, and the first angle adjusting member 813 passes through the strip-shaped hole and is threadedly connected with nuts on the upper and lower sides to be positioned; in this way, the height of the higher end of the auxiliary conveyor belt body 811 can be adjusted, that is, the inclination angle between the auxiliary conveyor belt body 811 and the vertical direction can be adjusted.

[0036] Preferably, the auxiliary conveyor belt frame 812 also has a conveyor belt second angle adjusting member 814, which is similar to the foregoing angle adjusting structure but has a different direction (for example, perpendicular), specifically, at two positions where the auxiliary conveyor belt frame 812 is connected to both ends of the auxiliary conveyor belt body 811, one side is hinged and the other side is adjustably connected through a hinged screw rod and a strip-shaped hole (and a nut) in cooperation, so as to be able to be turned over and adjust the inclination angle between the auxiliary conveyor belt body 811 and the horizontal plane.

[0037] Further, the bottom of the auxiliary conveyor belt frame 812 also has a conveyor belt height adjusting member 815. For example, through holes are provided at the four corners of the bottom of the auxiliary conveyor belt frame 812, vertical screw rods are inserted and positioned through nuts, and the bottom of the vertical screw rod has a mounting plate for connecting to the ground.

[0038] Figure 5 When the shown preferred auxiliary conveyor belt 81 is in use, after being installed on the ground, the overall height of the auxiliary conveyor belt frame 812 can be adjusted, that is, the overall height of the upper surface of the auxiliary conveyor belt 81 can be adjusted; combined with the adjustment of the foregoing two angles, it can flexibly adapt to different situations and better fit the bottom surface of the profile for support and conveying. Optionally, the profile horizontal placement guide frame 8 also has a frame with a similar structure, and the angle and height of the profile horizontal placement guide frame 8 can be adjusted.

[0039] Please refer to Figure 1 , Figure 4 , Figure 6 , Figure 7, in a more specific embodiment, the hook 3 is connected to the suspension conveyor rack 1 through a hanger 30. The upper part of the hanger 30 is movably connected to the suspension conveyor rack 1. The specific conveying and connecting methods are prior art and will not be elaborated here. In this solution, the lower part of the hanger 30 is a hook frame 301, and the upper end of the hook 3 is connected to the hook frame 301 (such as a hanging connection). A steering positioning portion 302 is fixedly connected above the hook frame 301. The hook frame 301 and the steering positioning portion 302 are arranged to be rotatable relative to the suspension conveyor rack 1. For example, the hanger 30 has a rod portion, the hook frame 301 is rotatably connected to the rod portion, and there is a gap between the steering positioning portion 302 and the rod portion without hindering rotation; or the whole hanger 30 is rotatable at the connection with the suspension conveyor rack 1; etc. Outside one side of the suspension conveyor rack 1, a first pushing mechanism 11 and a second pushing mechanism 12 are sequentially arranged along the conveying direction. The first pushing mechanism 11 and the second pushing mechanism 12 are specifically connected to the steering device frame, and the position between the steering device frame and the suspension conveyor rack 1 is fixed. The first pushing mechanism 11 and the second pushing mechanism 12 are located at the suspension transverse section 10 or the upstream side of the suspension transverse section 10. Outside the other side of the suspension conveyor rack 1, a positioning baffle 13 is provided. The positioning baffle 13 is also specifically fixedly or adjustably arranged on the steering device frame. The first pushing mechanism 11, the second pushing mechanism 12 correspond to the positioning baffle 13 and correspond to the steering positioning portion 302. Specifically, it means that the heights and positions of these components can correspond to each other, so as to realize the required functions described later.

[0040] Please refer to Figure 7 , the steering positioning portion 302 has a V-shaped structure, including a first steering rod 3021 and a second steering rod 3022 arranged at an angle. The first pushing mechanism 11 has a first pushing portion 111 for selectively pushing the first steering rod 3021 and / or the second steering rod 3022 to rotate the steering positioning portion 302; the second pushing mechanism 12 has a second pushing portion 121 for selectively pushing the side of the steering positioning portion 302 without the first steering rod 3021 and the second steering rod 3022 to make the first steering rod 3021 and the second steering rod 3022 both contact the positioning baffle 13. It should be noted that Figure 6 , Figure 7 shows the retracted states of the first and second pushing mechanisms, as well as the positions of the first and second pushing portions at the ends when the first and second pushing mechanisms are in the extended states, so as to clearly indicate the actions. In fact, the pushing mechanisms and the pushing portions at the ends are of course fixedly connected. The first pushing mechanism 11 and the second pushing mechanism 12 are, for example, cylinders or hydraulic cylinders or other mechanisms that can drive movement to achieve expansion and contraction.

[0041] More specifically, as Figure 7As shown, the first pushing part 111 is in the shape of a plate or a rod extending towards the positioning baffle 13 and has a rotatable rolling friction part 112, such as a roller, at its end, so that the pushing and rotating process can be better realized without being stuck due to friction or other reasons. The second pushing part 121 has a groove structure with an opening facing the positioning baffle 13, and the inner side of the groove structure of the second pushing part 121 can accommodate and support the part of the steering positioning part 302 facing away from the first steering rod 3021 and the second steering rod 3022. The second pushing part 121 and the steering positioning part 302 are both plate-shaped with a certain thickness, for example.

[0042] The hook frame 301 is plate-shaped with a hook hole. The angular position of the plane where the hook frame 301 is located corresponds to the angular bisector of the angle formed by the first steering rod 3021 and the second steering rod 3022. Thus, as shown in the lower half of Figure 7 , when both the first steering rod 3021 and the second steering rod 3022 contact the positioning baffle 13, the hook frame 301 is perpendicular to the positioning baffle 13. In this way, after the first pushing mechanism 11 makes a rough steering, the second pushing mechanism 12 is used for accurate angle positioning. Preferably, the part of the steering positioning part 302 without the first steering rod 3021 and the second steering rod 3022 is in a circular structure, and the groove structure of the second pushing part 121 is in a V shape. There is a relationship of a tangent arc and a plane between the two, so that the steering positioning part 302 can be further rotated to the required angle better after being pushed. Preferably, both the first steering rod 3021 and the second steering rod 3022 are in a triangular structure with a gradually decreasing size towards the free end. The side angle of the triangle makes it more convenient to be toggled and rotated by the first pushing mechanism 11. At the same time, the ends of the first steering rod 3021 and the second steering rod 3022 are thinner, which is convenient for precise positioning through the contact of two points with the positioning baffle 13.

[0043] The upper end of the lifting hook 3 is an upper hook part, and the upper hook part is hung on the hook frame 301 through the hook hole. In the prior art, the actually applied lifting hooks 3 are divided into two categories: positive hooks and reverse hooks. For positive hooks, both the upper hook part and the lower hook part face the same side of the lifting hook 3. For reverse hooks, the planes where the upper hook part and the lower hook part are located are perpendicular to each other. And in some processes, positive hooks and reverse hooks are arranged at intervals, so that the actions of the first and second pushing parts need to be performed every other lifting hook. Finally, it can be realized that in the state after the lifting hook 3 passes through the areas of the first pushing mechanism 11 and the second pushing mechanism 12, the lower hook parts all face the transverse conveying frame 2, that is Figure 3 the state shown, which is convenient for unhooking. In addition, it can also be selected to have an identification mechanism such as a sensor to control the selective actions of the first pushing mechanism 11 and the second pushing mechanism 12, so as to achieve the required final facing state of the hook according to the actual hanging situation.

[0044] Please refer to Figure 3, preferably, the hooking device 5 includes a hooking guide frame 52. A hooking portion 51 is slidably connected to the hooking guide frame 52 through a linear hooking guide rail assembly. The hooking portion 51 or the linear hooking guide rail assembly is connected with a hooking driving mechanism. The movable direction of the hooking portion 51 is fixedly or adjustably set to face obliquely downward, and the hooking portion 51 can reciprocate to continuously strike the lifting hook 3 multiple times. The hooking portion 51 may be selected as a transverse strip with a certain length, so as to be able to work on a row of lifting hooks 3 simultaneously. The surface of the hooking portion 51 may be selected as rubber or other soft or elastic materials, so as to avoid damaging the lifting hook 3 and avoid generating excessive noise. More specifically, in the illustrated preferred embodiment, the connection relationship between the hooking guide frame 52 and the machine frame is hinged at one end and the height of the other end is adjustable, so as to be able to adjust the inclination angle of the hooking guide frame 52 and the linear guide rail assembly thereon, that is, to adjust the movable direction of the hooking portion 51; setting the hooking direction to be inclined downward at a certain angle helps to push the lifting hook 3 and helps to cause the vibration of the lifting hook 3 in the length direction. Specifically, for example, a hooking motor is installed on the hooking guide frame 52, and the output end of the hooking motor and the linear guide rail assembly form a crank-slider mechanism, converting the continuous rotation of the motor into the reciprocating linear movement of the hooking portion 51, so as to stably achieve the required high-frequency striking effect.

[0045] Please refer to Figure 3 , Figure 8 , preferably, the pushing-back device 6 includes a pushing-back fixing frame 62. The pushing-back fixing frame 62 is fixedly installed on the machine frame. A pushing-back rotating arm 63 is rotatably connected to the pushing-back fixing frame 62 on the side close to the hooking device 5 (i.e., the side close to the profile). One end of the pushing-back rotating arm 63 protrudes toward the side close to the hooking device 5 and has a hooking portion 61 at the end. The pushing-back rotating arm 63 is also connected with a limiting spring 64. The hooking portion 61 may be selected as a transverse strip with a certain length, so as to be able to work on a row of lifting hooks 3 simultaneously. The surface of the hooking portion 61 may be selected as rubber or other soft or elastic materials, so as to avoid damaging the lifting hook 3 and avoid generating excessive noise. The solution with the pushing-back rotating arm 63 and the limiting spring 64 provides more buffering and rebounding effects compared with simply directly setting the hooking portion 61, which is more beneficial to the unhooking process. More specifically, in the illustrated preferred embodiment, the middle part of the pushing-back rotating arm 63 is rotatably connected to the pushing-back fixing frame 62, thus forming a lever structure. The upper end of the pushing-back rotating arm 63 is connected to the pushing-back fixing frame 62 or the fixed part of the machine frame through a limiting spring 64 (specifically a tension spring); Figure 8 The natural state of the tension spring is shown in

[0046] Please refer to Figures 9 to 11 , preferably, the ejector device 7 includes a first-level lifting mechanism 72 located at the bottom and a second-level lifting mechanism 73 connected to the upper part of the first-level lifting mechanism 72. The upper part of the second-level lifting mechanism 73 has an ejector part 71. The first-level lifting mechanism 72 can drive the second-level lifting mechanism 73 to lift and lower, and the second-level lifting mechanism 73 can drive the ejector part 71 to lift and lower. The two-level lifting method makes the movement of the ejector part 71 complex and controllable. For example, it can achieve several rapid upward strikes and then strike again after a certain period of time; or first lift the profile to a certain height and then slightly shake the profile in a reciprocating swing manner; etc. It should be noted that in some embodiments, the ejector device only pushes and holds the profile, and in some cases, it can achieve unhooking, but there will still be situations such as failure and jamming, and the success rate is difficult to guarantee. Therefore, in this solution, it is preferably that the ejector part 71 can reciprocate up and down to continuously strike the profile 4 multiple times. By adopting this vibration-like method, the situation of structural jamming can be effectively prevented, and the unhooking success rate is significantly improved. The ejector part 71 can be selected to have a certain length. In the direction along the width of the profile 4, the size of the ejector part 71 is greater than the width of one profile, so as to be able to work on a row of profiles 4 simultaneously. And, the upper surface of the ejector part 71 preferably has an ejector pad, such as rubber or other soft or elastic materials, so as to avoid damaging the profile 4 and generating excessive noise. More preferably, the rising direction of the ejector part 71 is fixedly or adjustably set to face obliquely upward, which is more convenient for pushing the profile and facilitating the unhooking of the profile.

[0047] More specifically, in the Figures 9 to 11 preferred embodiment shown, the second-level lifting mechanism 73 includes a second-level lifting base 731. A second-level lifting motor is provided on the second-level lifting base 731. The output end of the second-level lifting motor is drivingly connected to two second-level lifting eccentric shafts 732. The two second-level lifting eccentric shafts 732 are horizontally distributed and can rotate synchronously. The eccentric parts at the ends of the two second-level lifting eccentric shafts 732 are rotatably connected to the ejector part 71; and, the positions of the two rotation connection points of the ejector part 71 with the two second-level lifting eccentric shafts 732, and the axis positions of the two second-level lifting eccentric shafts 732 form the four vertices of a parallelogram; thus realizing the lifting and lowering of the ejector part 71 driven by the rotation of the motor. On the one hand, the ejector part 71 can achieve rapid and stable reciprocating lifting and lowering, and on the other hand, it also forms the aforementioned rising process facing obliquely upward, applying a lateral force to the profile 4. Please also refer to Figure 2 , where the perspective of the ejector device 7 is the same as that of Figure 11The same applies. The process of the lifting of the blank holding part 71 is actually achieved through a clockwise circular motion. As a result, the profile 4 will be subjected to a component force to the right applied by the blank holding part 71 (especially when the upper surface of the blank holding part 71 has a blank holding pad or the like that can give it a relatively large coefficient of friction). Therefore, while pushing the profile 4 upward, it can also push the profile to the side away from the hook 3, which is more conducive to unhooking. And after unhooking, the profile 4 will continue to gradually move away from the hook 3 and will not be hooked onto the hook 3 again.

[0048] For the specific manner of the synchronous movement of the two secondary lifting eccentric shafts 732, for example, both of the two secondary lifting eccentric shafts 732 are rotatably connected to the 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 that are of the same size and are meshed in sequence; 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, and the secondary lifting motor is drivingly connected to the driving gear. It can be understood that in some other feasible embodiments, two motors are used to control the two secondary lifting eccentric shafts 732 respectively; in this preferred embodiment, one motor is used for synchronous drive, with one eccentric shaft being the driving one and the other being the driven one, which can simplify the control, reduce the cost, and ensure the consistency of the rotation of the two eccentric shafts.

[0049] Furthermore, the primary lifting mechanism 72 includes a primary lifting base 721. A primary lifting motor is arranged on the primary lifting base 721. The output end of the primary lifting motor is drivingly connected to a primary lifting eccentric shaft 722. The eccentric part 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 the secondary lifting base 731; the secondary lifting base 731 is also connected with a downwardly extending lifting guide post 734. A lifting guide sleeve 724 is arranged on the primary lifting base 721. The lifting guide post 734 is slidably connected with the lifting guide sleeve 724 in a matching manner. In this way, a crank-slider mechanism is formed to convert the rotation of the primary lifting motor into the reciprocating lifting of the secondary lifting base 731. To ensure stable lifting, it is preferred that the lifting guide post 734 and the lifting guide sleeve 724 are four groups 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, and then two primary lifting support rods 723 are connected. The two primary lifting support rods 723 are respectively located on both sides of the secondary lifting base 731.

[0050] Preferably, a device base 74 is provided below the first-level lifting base 721. One side of the first-level lifting base 721 is hinged to the device base 74, and the other side of the first-level lifting base 721 is adjustably connected to the device base 74 through a blanking angle adjusting member 741. The blanking angle adjusting member 741 includes, for example, an angle adjusting screw rod arranged vertically. The lower end of the angle adjusting screw rod is hinged to the device base 74. A strip-shaped hole is formed in the first-level lifting base 721. The upper end of the angle adjusting screw rod passes through the strip-shaped hole of the first-level lifting base 721. Two angle positioning nuts are threadedly connected to the angle adjusting screw rod, and the two angle positioning nuts are respectively located on the upper and lower sides of the strip-shaped hole of the first-level lifting base 721. To ensure stability, two groups of blanking angle adjusting members 741 are preferably provided. In this way, the inclination angle of the first-level lifting base 721 and the overall structure above it can be adjusted, realizing lifting towards the upper oblique direction. Further preferably, the inclination angle corresponds to the inclination angle of the profile 4 at this time, and the upper surface of the blanking part 71 is substantially parallel to the bottom surface of the profile, which is more conducive to the blanking effect. In addition, preferably, a blanking height adjusting member 742 for adjusting the height position of the device base 74 is further provided at the bottom of the device base 74. Its structure is, for example, similar to that of the blanking angle adjusting member 741, the difference being that since it is only for vertical lifting, the hole type for the penetrating screw rod can be selected as a round hole; the bottom of the blanking height adjusting member 742 is fixedly connected to the ground, so that the overall position of the blanking device 7 is fixed. Therefore, the preferred blanking device 7 shown in the figure is more flexible in use and can be adjusted to the required height, angle, etc. according to the actual situation.

[0051] In summary, the unhooking system for a suspended profile of the present invention is provided with a blanking device below the profile, and a hook engaging device and a pushing-back device are correspondingly arranged on both sides of the hook. Through the cooperation of these three devices, namely the hook engaging device, the pushing-back device, and the blanking device, a fast and highly successful unhooking process can be achieved; among them, the blanking device can lift and / or vibrate one end of the profile close to the hook, and the hook engaging device and the pushing-back device can swing and / or vibrate the hook in the direction of separating from the profile, so as to efficiently separate the profile from the hook and effectively avoid situations such as incomplete separation and separation failure; and, the above process can be carried out on multiple hooks and profiles in a row at the same time, so the time can be greatly saved compared with unhooking one by one.
