[0002] With the development of mechanical manufacturing automation and intelligent control technology, the automated elements in modern factory logistics are also increasing. For example, in traditional technologies, the scheduling of materials at each workstation in a factory often relies on manual handling or the use of vehicles such as forklifts by workers, which is inefficient and labor-intensive. Now, a hanging system is used to achieve the transfer of materials.

[0003] As disclosed in the Chinese patent document with the publication number CN201710106862.6, a garment hanging system is disclosed, which includes an inbound structure, a guide rail, and an outbound structure. The clothes hangers slide on the guide rail to achieve the scheduling of each workstation. However, due to fire safety requirements in large warehouses or factories, multiple fire doors will be installed. The fire doors are installed in a suspended manner on the ceiling, and when the fire doors need to be closed, the control of the fire door suspension device is lowered. During this process, the fire doors interfere with the track, making it difficult to design the track laying. Summary of the Invention

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0047] Embodiment 1, a disconnection device applicable to a track and its control method, as Figure 1 shown, includes Track 1 and Track 2. One end of Track 2 is rotatably connected to a swing arm 3. As the swing arm 3 rotates, Track 1 and Track 2 are switched between a connected state and a disconnected state.

[0048] In practical applications, there are components that need to be lifted in the workshop, such as a fire door (not shown in the figure). In the normal state, the fire door is always above the track, and the entire track is in a connected state. When the fire door needs to be closed, the fire door descends.

[0049] At this time, it enters S01, the avoidance object sensing step, and the process is as follows Figure 7 shown, and the structure is as follows Figure 1 shown. An avoidance detection device 4 is installed on the track 1. The bracket 41 is U-shaped and installed on the track 1. An irradiation switch 42 is installed on the bracket 41. A reflector 43 is installed on the other side of the track 2. In the normal state, the optical path of the irradiation switch 42 is reflected by the reflector 43 and received by the irradiation switch 42. When the fire door descends, it blocks the optical path of the irradiation switch 42, and the irradiation switch 42 cannot normally receive the reflected optical path. That is, the control system captures the descending action of the fire door through the signal change of the irradiation switch 42, which is regarded as the control system receiving the avoidance signal of the avoidance detection device 4.

[0050] The control system can use a mature control system in the prior art. In terms of hardware, it can be a PC, a numerical control table, a single-chip microcomputer, a server, etc. Its control software can also adopt the numerical control software in the prior art. The hardware and software of the control system are both content of the prior art and are not limited here. Those skilled in the art can choose by themselves.

[0051] Subsequently, it enters S02, the locking device unlocking step.

[0052] As Figure 1 and Figure 2 shown, a locking device 5 is installed on the track 1. The locking device 6 includes a moving seat 52 and a locking drive device 51. The locking drive device 51 can adopt a conventional drive component in the prior art. In this embodiment, an electric cylinder is adopted. The electric cylinder pushes the entire moving seat 52 to slide back relative to the track 1.

[0053] A support rod 53 is installed on the moving seat 52. Specifically, the moving seat 52 includes a fixed rod block 521, and the fixed rod block 521 is provided with a receiving groove with a downward notch. The support rod 53 is T-shaped and includes a main rod 531 and a sub-rod 532, which extend perpendicularly to each other. The sub-rod 532 is stuck in the receiving groove, and the limiting block 54 supports the lower part of the sub-rod 532 to complete the fixation.

[0054] One end of the swing arm 3 includes a support block 31, and a fitting groove 311 is provided on the support block 31. In the original connected state of the track 1 and the track 2, the main rod 531 protrudes and is stuck at the fitting groove 311, so that the locking device 5 supports the swing arm 3. In the S02 step, the moving seat 52 retreats, and the main rod 531 starts to separate from the support block 31.

[0055] As Figure 5 shown, in this case, it also includes a sensor for positioning, as Figure 5The unlocking sensor 71 and the locking sensor 72 therein. These sensors can be photoelectric sensors or microswitches of the physical contact type. Their function is to sense whether a certain component has reached the predetermined sensing position.

[0056] The unlocking sensor 71 is installed at a preset position on the first track 1. When the moving seat 52 moves into the sensing range of the unlocking sensor 71, the unlocking sensor 71 sends a sensing signal to the control system, and the control system controls the locking drive device 51 to stop. At this time, the main rod 531 is completely separated from the support block 31, and the swing arm 3 swings downward under its own weight, providing a clearance space for the descent of the fire door.

[0057] As Figure 3 shown, the swing arm 3 includes a rotating shaft 33. On both sides of the rotating shaft 33, a main arm 32 and a sub-arm 34 are respectively connected, that is, both the main arm 32 and the sub-arm 34 rotate around the rotating shaft 33. When the main arm 32 swings downward due to its own weight, the sub-arm 34 rotates synchronously and finally abuts against the lever 62.

[0058] When the fire door is used up and returns to its original position, the track needs to be restored from the disconnected state to the connected state. The process is as Figure 8 shown, and the structure is as Figure 1 and Figure 3 shown.

[0059] When the fire door rises, the ascending action is also captured by the avoidance detection device 4, and the control system controls the swing arm 3 to return to its original position. Specifically, it enters S03, the swing arm return step. As Figure 3 and Figure 6 shown, the drilling and rotating device 6 includes a rotating drive 61. In this embodiment, its specific behavior can be a motor. The output shaft of the motor is connected to the lever 62.

[0060] The lever 62 rotates under the drive of the motor, abuts against the lower surface of the sub-arm 34, drives the main arm 32 to swing upward, and reconnects the second track 2, the swing arm 3 and the first track 1. As Figure 6 shown, when the swing arm 3 or the lever 62 swings to the closing sensor 73, it is considered that the swing arm 3 has swung in place, and the motor stops.

[0061] At this time, it enters S04, the locking device relocking step. The locking device 5 returns to its original position and relocks the position of the swing arm 3. As Figure 5 shown, when the moving seat 52 moves into the sensing area of the locking sensor 72, it is considered that the return is completed, and the control system controls the electro-magnet to stop.

[0062] Finally, it enters the last step, that is, S05, the lever reset step. As Figure 3 and Figure 6As shown, the rotation driver 61, i.e., the motor, starts to reverse, driving the lever 62 to rotate back to the initial position. When the lever 62 rotates into the sensing range of the reset inductor 74, it is considered in place, and the control system controls the motor to stop.

[0063] In some cases, when a fault occurs in the power supply system and the entire device is in a power-off state. At this time, the user can choose to manually swing the swing arm 3 to the off state.

[0064] Specifically, as Figure 4 shown, the limit block 54 is rotatably connected to the moving seat 52. The user rotates the limit block 54 so that it no longer supports the auxiliary rod 532, operates the auxiliary rod 532 to rotate out of the fixed rod block 521, and then operates the entire support rod 53 to slide relative to the moving seat 52 so that the main rod 531 is disengaged from the support block 31.
