Description

Technical Field

[0001] This utility model belongs to the field of aviation cable ground manufacturing technology, and in particular relates to an automatic unloading device. Background Technology

[0002] In recent years, with the rapid development of advanced military and civilian aircraft and weaponry in my country, the number of type qualification test flights, airworthiness certification test flights, and demonstration and verification test flights has surged, making the modification work of test aircraft increasingly arduous. The maximum cable usage for a single test aircraft has reached more than 20 kilometers. The most labor-intensive and time-consuming part of the test aircraft cable manufacturing process is the unwinding process. The process involves workers releasing the required length of cable from the finished cable roll according to the length and quantity specified in the process instruction sheet, cutting it, and then bundling the required quantity of unwinding cable into coils.

[0003] The traditional method of unloading cables involves two workers manually. One worker holds the cable reel and rotates it in a fixed sequence to release the cable, thus de-twisting it; the other worker pulls the cable end in a straight line for the required length. This process is repeated multiple times to unload the required number of cables of the same length. Clearly, this traditional method suffers from extremely low production efficiency and extremely high labor costs. Summary of the Invention

[0004] Purpose of the invention: To address the problems of low unwinding efficiency and low automation in the modification of existing testing machines, this utility model provides an automatic unwinding device. It is a motor-driven device with multiple winches for unwinding and a single winch for winding, capable of unwinding and reeling up to 10 cables of any length in a single operation. The entire unwinding process requires no manual intervention, greatly improving efficiency and automation. Its design is reasonable, its structure is compact, and its automation level is high.

[0005] Technical solution:

[0006] An automatic unloading device includes: an equipment frame 3, multiple damping shafts 1, multiple winding reels 2, multiple winding bundle rings 4, two bundle bell mouths 5, a stranded wire reduction motor 7, a coupling 8, a bearing housing 9, a stranded wire shaft 10, a stranded wire reel 11, a meter-counting wheel 13, and multiple finished cables 14.

[0007] A cable bundling ring 4, a bundling horn 5, a meter-counting wheel 13, another bundling horn 5, and a stranded reel 11 are sequentially fixed on the equipment frame 3. Two cable reels 2 are arranged on both sides of the equipment frame 3. The cable reels 2 are specifically mounted on the equipment frame 3 via a damping shaft 1. One end of the finished cable on each cable reel 2 passes through the cable bundling ring 4, one bundling horn 5, the meter-counting wheel 13, and the other bundling horn 5 in sequence and is then fixed on the stranded reel 11. The output shaft of the stranded reel reduction motor 7 is connected to the stranded reel 11 via a coupling 8 to control the rotation of the stranded reel 11 and achieve automatic unloading. The stranded reel reduction motor 7 is connected to the coupling 8 in a bearing-mounted manner and outputs to the stranded shaft 10 through the bearing seat 9, thereby driving the stranded reel 11 to rotate.

[0008] Furthermore, a plurality of stranding posts 12 are provided on the lower end surface of the stranding reel 11, and the upper end surface 15 of the stranding reel is connected to the upper end of the stranding posts 12.

[0009] Furthermore, it also includes: a control board 6, a touch screen 16, and a brake 17, wherein the touch screen 16, the stranded wire geared motor 7, the meter-counting wheel 13, and the brake 17 are electrically connected to the control board 6.

[0010] Furthermore, the lower end face of the stranded wire reel is provided with multiple radial grooves, and the lower end of the stranded wire column 12 passes through the radial grooves and is fixed by a nut.

[0011] Furthermore, a nut is provided on the damping shaft 1 to increase the damping between the winding reel 2 and the equipment frame 3.

[0012] Furthermore, multiple wire coiling rings 4 and two coiling horn openings 5 ​​are welded onto the equipment frame 3.

[0013] Beneficial effects:

[0014] (1) The present invention provides tension to the cable 14 by means of the damping shaft 1, which ensures that the cable can be tightly and firmly wound on the hanging post 12 when it is finally coiled.

[0015] (2) The present invention performs the first clustering of the cables on the winding reel 2 through the clustering ring 4, and performs the second clustering of up to 10 cables through the clustering horn 5. The clustering and routing problem of up to 10 cables is solved by the second clustering method, so that the routing of up to 10 cables does not interfere and the clustering is stable.

[0016] (3) The present invention uses a stranded wire reduction motor 7 as the winding power of the stranded wire reel 11, which can output a sufficiently constant torque to the stranded wire reel 11, and in particular, can also provide a braking torque opposite to the direction of rotation, and has the advantages of simple structure and accurate torque control.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0021] Example 1

[0022] like Figures 1-2 As shown, this application provides an automatic unloading device, wherein: the damping shaft 1 is installed on the equipment frame 3, the winding reel 2 is connected to the equipment frame 3 through the damping shaft 1, and the finished cable 14 is wound on the winding reel 2, wherein one end of the cable is fixed to the winding reel 2.

[0023] The bundling ring and the bundling horn are welded to the equipment frame 3. The finished cable 14 wound on the winding reel 2 passes through the winding bundling ring 4 and converges to the bundling horn 5 to complete the bundling of the finished cable 14.

[0024] The meter wheel 13 is mounted on the equipment frame 3 via its own bracket. After the finished cable 14 is bundled, the finished cable 14 is tied to the winding hole of the stranded reel 11 via the meter wheel 13, thus fixing the other end of the finished cable 14.

[0025] The stranded wire reduction motor 7 is mounted on the equipment frame 3 and connected to the coupling 8 in the form of bearing mounting. The output is sent to the stranded wire shaft 10 through the bearing seat 9, thereby driving the stranded wire reel 11 to rotate.

[0026] As the stranding reel 11 rotates, the finished cable 14 is wound onto the stranding post 12 connected to the stranding reel 11. By adjusting the damping force on the damping shaft 1, the finished cable obtains a suitable tension during winding. The finished cable 14 is prevented from detaching from the stranding post 12 by locking the upper end face 15 of the stranding reel.

[0027] The control board 6 and the touch screen 16 are mounted on the equipment rack 3. The target length of the current production line is set through the touch screen 15, and the touch screen 16 inputs the set target length signal to the control board 6.

[0028] The meter wheel 13 collects the length signal of the cable during winding and inputs it to the input terminal of the control board 6. The output terminal of the control board 6 is connected to the stranded wire reduction motor 7. The start and stop of the stranded wire reduction motor 7 are controlled by comparing it with the target length of the cable.

[0029] The brake 17 is installed at the bottom of the stranded wire reduction motor 7. When the length collected by the meter wheel 13 meets the target length for this operation, the stranded wire reduction motor 7 stops rotating, and at the same time, the control board 6 outputs a start signal to the brake 17.

[0030] The brake 17 transmits braking torque to the stranded wire reduction motor 7, locks the stranded wire reel 11, and completes closed-loop control of the entire cable winding action.

[0031] When the stranded reel 11 is locked, the cable between the meter wheel 13 and the stranded reel 11 is cut manually, and the finished cable 14 is untied from the end of the cable tied to the stranded reel 11.

[0032] Open the upper end face of the stranding reel, loosen the mounting nut of the stranding column 12, and move the stranding column 12 toward the center of the stranding reel 11 to eliminate the tension of the finished cable 14 wound on the stranding column, so that the finished cable 14 can be taken out after unwinding.

[0033] This utility model's automatic unloading device solves the problems of low efficiency, large workload, and low automation of traditional manual unloading. It enables the unloading and reeling of up to 10 cables of any length in a single operation. The unloading process requires no manual intervention, increasing the average unloading efficiency by more than 10 times, significantly improving the efficiency of modified cable manufacturing, and effectively ensuring the flight testing of military and civilian test aircraft and weapons.
