[0002] In the processing of painting or drying sheet metal parts, a suspension production line is usually used for transportation, loading and unloading. In the prior art, sheet metal parts are usually manually installed on a hanging tool, and then the hanging tool and the workpiece can be transported to corresponding workstations for processing through a hanging tool conveying device. After the workpiece is processed, it is also necessary to manually disassemble the positioning parts and separate the workpiece from the hanging tool and then take it down, which is also time-consuming and laborious, resulting in low production efficiency. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a loading and unloading device for a suspension system, which solves the problems of high cost and low efficiency caused by manual loading and unloading.
[0004] To achieve the above purpose, the utility model provides the following technical solution: a loading and unloading device for a suspension system, including a frame and a hanging tool. The frame is provided with a loading mechanism, a unloading mechanism and a transfer mechanism arranged staggeredly in the height direction. The hanging tool is provided with a first traction part, a second traction part and a third traction part respectively corresponding to the transfer mechanism, the loading mechanism and the unloading mechanism. The projection of the transfer mechanism on the horizontal plane intersects with those of the loading mechanism and the unloading mechanism at the same time. When the loading mechanism suspends and conveys the hanging tool to the transfer mechanism through the second traction part, the transfer mechanism takes the hanging tool from the loading mechanism through the first traction part. When the transfer mechanism suspends and conveys the hanging tool to the unloading mechanism, the unloading mechanism takes the hanging tool from the transfer mechanism through the third traction part, and at the same time, the transfer mechanism disconnects the first traction part from the transfer mechanism through a decoupling mechanism.
[0005] By adopting the above technical solution: when the unloading mechanism has received the hanging tool through the third traction part, the decoupling mechanism will disconnect the first traction part from the transfer mechanism accordingly, so that the subsequent unloading operation is completed by the unloading mechanism. The whole process of loading and unloading of this suspension system is an automated operation, which is beneficial to cost saving and improvement of processing efficiency.
[0006] Wherein, the first traction part, the second traction part and the third traction part are arranged in sequence from top to bottom.

[0013] The hook detachment mechanism includes a hook detachment bracket connected to the frame and a hook lifting column connected to the side of the traction hook. A sloping guide rib is provided on the hook detachment bracket.

Detailed implementation manners
[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] Embodiment 1
[0030] This embodiment provides as Figure 1A hanging system loading and unloading device is shown, which includes a frame 1 and a hanger 2. The hanger 2 in this scheme is a rod body, and the rod body of the rod body is used to set materials. The top of the rod body is provided with a first traction part, a second traction part and a third traction part. The frame 1 is staggeredly provided with a loading mechanism 3, a unloading mechanism 4 and a transfer mechanism 5 in the height direction, and the first traction part, the second traction part and the third traction part on the hanger 2 correspond to the transfer mechanism 5, the loading mechanism 3 and the unloading mechanism 4 respectively, to ensure that any mechanism among the transfer mechanism 5, the loading mechanism 3 and the unloading mechanism 4 can transfer the hanger 2. In this embodiment , the transfer mechanism 5 needs to intersect with the projections of the loading mechanism 3 and the unloading mechanism 4 on the horizontal plane at the same time, so that the transfer mechanism 5 can perform transfer operations between the loading mechanism 3 and the unloading mechanism 4 at the same time; in this embodiment, when the loading mechanism 3 suspends and transports the hanger 2 to the transfer mechanism 5 through the second traction part, the transfer mechanism 5 takes the hanger 2 from the loading mechanism 3 through the first traction part; when the transfer mechanism 5 suspends and transports the hanger 2 to the unloading mechanism 4, the unloading mechanism 4 takes the hanger 2 from the transfer mechanism 5 through the third traction part, and the transfer mechanism 5 disengages the first traction part from the transfer mechanism 5 through the uncoupling mechanism 6.
[0031] When the loading mechanism 4 is under the control of the conveyor 5, the first traction part of the conveyor 5 is detached from the loading mechanism 3, and the second traction part of the conveyor 5 is detached from the loading mechanism 3, and the conveyor 5 is used to transport the hanging tool 2 to the loading mechanism 3.
[0032] Specifically, Figure 1As shown in the figure, the first traction part, the second traction part and the third traction part in this embodiment are arranged in sequence from top to bottom. Accordingly, the transfer mechanism 5, the loading mechanism 3 and the unloading mechanism 4 corresponding to the first traction part, the second traction part and the third traction part are also arranged in sequence from top to bottom. Among them, the transfer mechanism 5 includes a transfer conveyor chain 502, and a traction hook 503 that is hooked to the first traction part is also connected to the transfer conveyor chain 502. The traction hook 503 operates cyclically under the traction of the transfer conveyor chain 502. Furthermore, the loading mechanism 3 includes a loading conveyor chain 302, and the unloading mechanism 4 includes an unloading conveyor chain 402. The loading conveyor chain 302 and the unloading conveyor chain 402 are both arranged horizontally. Such a horizontal arrangement facilitates the hanging tool 2 to be suspended on the loading conveyor chain 302 through the second traction part, and facilitates the hanging tool 2 to be suspended on the unloading conveyor chain 402 through the third traction part.
[0033] Furthermore, the transfer mechanism 5 of this embodiment includes a first bracket 501 connected to the frame 1. The transfer conveyor chain 502 is installed on the first bracket 501. A plurality of L-shaped plates are fixedly connected to the transfer conveyor chain 502. A traction hook 503 that is hooked to the first traction part is rotatably connected to the vertical plate surface of the L-shaped plate. A plurality of traction hooks 503 are provided according to production requirements. The traction hook 503 is connected to the chain belt of the transfer conveyor chain 502 through the L-shaped plate. When the transfer conveyor chain 502 operates, the chain belt of the transfer conveyor chain 502 will drive the traction hook 503 to move.
[0034] Furthermore, the loading mechanism 3 includes a second bracket 301 connected to the frame 1. The loading conveyor chain 302 with a horizontally arranged transportation plane is installed on the second bracket 301. The chain belt of the loading conveyor chain 302 extends out of the second bracket 301 in the width direction. A first chain support block 303 for supporting the bottom of the chain belt is provided on the second bracket 301. The bottom end of the chain belt is in sliding contact with the end surface of the first chain support block 303. The unloading mechanism 4 includes a third bracket 401 connected to the frame 1. The third bracket 401 is an L-shaped structure with a first part 4011 and a second part 4012. The unloading conveyor chain 402 with a horizontally arranged transportation plane is installed on the first part 4011 of the third bracket 401. An L-shaped double rail 403 connected to the frame 1 is provided at the connection between the first part 4011 and the second part 4012 of the third bracket 401. The third traction part is hung on the L-shaped double rail 403. The chain belt of the unloading conveyor chain 402 extends out of the first part 4011 in the width direction. The inner guide rail of the L-shaped double rail 403 guides the hanging tool 2 to be closely arranged against the chain belt of the unloading conveyor chain 402. The outer guide rail 7 is arranged along the chain belt of the unloading conveyor chain 402. A second chain support block 404 for supporting the bottom of the chain belt is provided on the first part 4011. The bottom end of the chain belt is in sliding contact with the end surface of the second chain support block 404. In order to facilitate the hanging tool 2 to enter the unloading mechanism 4, the end of the L-shaped double rail 403 close to the transfer mechanism 5 is arranged in an open shape.
[0035] AsFigure 2 As shown, the first traction part is a hanging ring 201 hooked to the traction hook 503, the second traction part is a hook 202, and the third traction part is a hemispherical slider 203. The spherical surface of the slider 203 faces downward and is in sliding contact with the L-shaped double rail 403. During the working process, the feeding conveyor chain 302, the discharging conveyor chain 402, and the transfer conveyor chain 502 are started simultaneously. Secondly, the fixture 2 is suspended on the chain belt on one side of the feeding conveyor chain 302 through the hanging ring 201. Then, the chain belt of the feeding conveyor chain 302 can drive the fixture 2 to move synchronously. At this time, a traction hook 503 of the transfer conveyor chain 502 just passes through the feeding conveyor chain 302 horizontally and connects the hook groove of the traction hook 503 with the hanging ring 201 at the top of the fixture 2. Since the hook 202 is suspended and connected to the feeding conveyor chain 302, the traction hook 503 of the transfer conveyor chain 502 can separate the hook 202 from the chain belt of the feeding conveyor chain 302 by pulling the hanging ring 201, so as to take away the fixture 2. Further, the transfer conveyor chain 502 transports the fixture 2 to the machining center. When the material on the fixture 2 is processed, it is still transported to the discharging conveyor chain 402 by the transfer conveyor chain 502. The inlet end of the discharging conveyor chain 402 is provided with an L-shaped double rail 403, which is used to cooperate with the slider 203 on the fixture 2. When the slider 203 on the fixture 2 enters the L-shaped double rail 403, the hook release mechanism 6 separates the hanging ring 201 from the traction hook 503, and the fixture 2 immediately disconnects from the traction hook 503 on the transfer conveyor chain 502. Then, the fixture 2 enters the discharging conveyor chain 402 along the L-shaped double rail 403 through the slider 203, and the chain belt of the discharging conveyor chain 402 transports the fixture 2 to the next process.
[0036] Embodiment 2

When the hook lifting column 602 slides in contact with the top surface of the guide rib 603 and the hook lifting column 602 rotates the traction hook 503 reversely along the top surface of the guide rib 603 to complete the hook release.
[0038] Embodiment 3
[0039] In this embodiment, the difference from Embodiment 1 is that the feeding mechanism 3 and the discharging mechanism 4 are both provided with mechanisms that can respectively adjust the heights of the feeding conveyor chain 302 and the discharging conveyor chain 402. Specifically, a feeding boom 304 is provided above the second bracket 301. A number of feeding supports are provided on the feeding boom 304. A rod groove is formed in the feeding support.

The inner side of the second discharging adjusting arm 409 is used to fix the outer guide rail 7 of the L-shaped double rail 403. Similarly, there are multiple connecting frames 407 in the discharging mechanism 4. By the cooperation of the discharging screw 406 and the discharging nut, the height of each connecting frame 407 can be adjusted, so as to adjust the discharging conveyor chain 402 to an inclined state for easy discharging.
[0040] In this solution, chain drives are used in both the feeding mechanism 3 and the discharging mechanism 4. Belt drives or chain plate drives can also be selected according to customer requirements. Chain drive is the best choice in the above embodiments.
[0041] It should be added that the transfer conveyor chain 502 is a closed-loop conveyor chain. Fixtures 2 are installed on it to mount materials for operations such as in-line spraying and drying of the materials. The transfer conveyor chain 502 can be connected to a machining center for operation. The purpose of this solution is to provide a loading and unloading device for this suspension system, which is used to achieve automatic loading and unloading, and a transfer mechanism 5 is established between the feeding mechanism 3 and the discharging mechanism 4.
