Description

Technical Field

[0001] This invention belongs to the technical field of parachute packaging, and more specifically, relates to a mechanized parachute rope threading device. Background Technology

[0002] Parachutes are crucial equipment in the aerospace field, and the speed of their folding and packing, as well as their safety during use, directly impact the efficiency of parachute preparation and the personal safety of the jumpers. In the parachute folding, packing, and packing process, parachute line packing is a critical step, requiring the lines to be threaded through several loops on the parachute pack. Currently, parachute line packing is generally done manually, requiring two operators: first, the lines are straightened and aligned, ensuring no tangling; then, one operator uses a packing needle to lift the loops in the pack, while the other uses a packing hook to thread all the lines into the loops on both sides in a specific order and segment. This manual method involves many repetitive actions, is time-consuming, and inefficient, often resulting in inconsistent line packing quality. Therefore, there is an urgent need to upgrade the parachute line packing process through mechanized equipment.

[0003] Existing technology CN113978736A proposes a parachute cord threading and winding device, which realizes mechanized operation of rapid cord threading and winding, greatly improving the efficiency of parachute cord management compared to manual operation. However, the device has drawbacks: the constraint on the parachute cords during the threading and winding process is limited, and the parachute cords, due to their relatively soft material, are easily disturbed, thus affecting the threading quality; in addition, the device can only thread each cord loop sequentially, and there is still a significant bottleneck in terms of parachute cord management efficiency. Therefore, the inability of this device to meet the needs of batch cord threading operations is the main reason why existing methods are difficult to improve cord threading efficiency.

[0004] Existing automated paracord sorting methods generally suffer from significant drawbacks in the cord threading process, making it difficult to balance efficiency and quality. On the one hand, existing methods struggle to effectively constrain and limit the cord bundles, affecting the uniformity of cord segment distribution and thus impacting the quality of paracord sorting. On the other hand, the small size of paracord loops, the close spacing between adjacent loops, and the certain width of the cord segments carried by the threading mechanism prevent the threading mechanism from being arranged according to the spacing between adjacent loops, making it difficult to achieve batch threading operations and severely restricting threading efficiency. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides a parachute rope threading device. Its purpose is to match the rope claws on the rope claw frame with the rope winding forks on the rope winding frame, thereby limiting the rope bundle on the rope winding forks. After the rope is threaded through the rope claws, the rope bundle is removed and fixed by matching the hooks on the rope fixing frame with the rope claws on the rope claw frame. This solves the technical problem of low threading efficiency and quality caused by soft rope loops and small spacing in existing parachute packaging processes.

[0006] To achieve the above objectives, in a first aspect of the present invention, a parachute cord threading device is provided, the device comprising:

[0007] The upper base is equipped with longitudinal and transverse guide rails.

[0008] The lower base is disposed parallel to the lower part of the upper base;

[0011] The rope claw frame is arranged in two parallel groups on both sides of the lower base and between the two groups of rope winding frames, and connected to the upper base. Its end is provided with several rope claws. The rope claws match the rope winding fork and are used to restrict the rope bundle on the rope winding fork to the middle of the rope claws.

[0012] The rope fixing frame is arranged in two parallel groups on both sides of the lower base. It is equipped with several hooks, which match the rope claws of the rope claw frame and are used to pass through the middle of the rope claw frame to remove and fix the rope bundle.

[0013] As a preferred embodiment of the present invention, each set of the rope claw frame includes two rows of rope claws; the rope claws on the two rows of rope claws are arranged alternately, such that the distance between two adjacent rope claws on each row of rope claws is twice the distance between two adjacent rope loops on the umbrella bag to be threaded.

[0014] As a preferred embodiment of the present invention, the rope claw on the rope claw frame includes a fixed claw and a movable claw, with a slot in the middle; the movable claw is located above the fixed claw and is used to restrict the rope bundle on the rope fork in the rope winding frame in the slot by opening and closing the movable claw.

[0015] As a preferred embodiment of the present invention, the rope claw frame is slidably connected to the upper base; the main body of the rope claw frame includes a telescopic structure for driving the rope claw to move between the upper base and the lower base.

[0016] As a preferred embodiment of the present invention, the distance between the two sets of rope winding frames does not exceed the width of the transverse guide rail.

[0017] As a preferred embodiment of the present invention, each set of the rope winding frame includes two rows of rope winding forks; the rope winding forks on the two rows of rope winding forks are arranged alternately, and the distance between each pair of matched rope winding forks and the rope claw is equal.

[0018] As a preferred embodiment of the present invention, the number of rope forks on each group of rope winding frames is equal to the number of rope claws on each group of rope claw frames, so that the rope forks and the rope claws correspond one-to-one.

[0019] As a preferred embodiment of the present invention, the rope fixing frame includes a number of telescopic rods matching the number of hooks, the hooks being located at the ends of the telescopic rods.

[0020] As a preferred embodiment of the present invention, the number of hooks on each group of rope fixing frames is equal to the number of rope claws on each group of rope claw frames, so that the hooks and rope claws are matched one-to-one.

[0021] As a preferred embodiment of the present invention, the device includes a motor, which is electrically connected to the rope winding frame, the rope guiding frame, the rope claw frame, and the rope fixing frame, respectively, for driving the rope winding frame to move in the lateral direction of the lower base, driving the rope guiding frame to move in the longitudinal and lateral directions of the upper base, driving the rope claw frame to move in the longitudinal direction of the upper base and / or in the lateral direction of the upper base, and driving the rope fixing frame to move electrically in the lateral direction of the lower base.

[0022] In summary, compared with the prior art, the above-described technical solutions conceived by this invention mainly possess the following technical advantages:

[0023] 1. Addressing the technical challenges of small individual rope loop size and close spacing between adjacent rope loops in existing parachutes, this invention discloses a parachute rope threading device. Utilizing the synergistic effect of various modules, the rope threading process is divided into a winding process, a rope retrieval process, and a rope threading process. Specifically, the device performs the winding process through the cooperation of a rope guide clamp and a winding frame, organizing the parachute ropes into uniform and neat "S"-shaped rope segments to avoid tangling and twisting. Next, the rope retrieval process is performed by matching the rope claws on the rope claw frame with the winding forks on the winding frame, effectively fixing and limiting multiple rope segments to minimize disturbance and maintain consistent spacing between segments, ensuring accuracy and precision for the threading process. Finally, the rope threading process is performed by matching the hooks on the rope fixing frame with the rope claws on the rope claw frame, removing and fixing the rope bundle. This enables parallel threading of multiple rope loops, thereby improving threading efficiency and quality.

[0024] 2. In this invention, the rope claws on the two rows of claws are staggered, and the distance between two adjacent rope claws on each row is twice the distance between adjacent rope loops on the umbrella bag to be threaded. Specifically, in the rope taking process, the threading mechanism fixes and limits the rope segments with consistent spacing. In particular, by setting the threading mechanism in multiple rows, firstly, it enables several rope loops to be threaded in batches and in parallel with an efficient batch threading strategy, improving threading efficiency; secondly, the multiple rows increase the distance between adjacent rope segments in each row, solving the spatial arrangement problem of batch threading mechanism, reducing mutual disturbance, and improving threading accuracy.

[0025] 3. In this invention, the rope-winding forks on the two rows of forks are staggered in the longitudinal direction of the lower base, and the distance between each pair of matching rope-winding forks and rope claws is equal. This makes it easier to achieve batch operation of the rope-retrieving process and improves the efficiency of the rope-retrieving process. At the same time, a series of pre-processing steps provide good operating conditions for the subsequent rope-threading process, further improving the accuracy and precision of paracord arrangement.

[0026] 4. The present invention also includes a motor, which is electrically connected to each module to drive the movement of the corresponding structure in each module on the upper or lower base, so as to complete the cooperation between the structures and then perform the rope winding process, rope picking process and rope threading process in sequence. Through the coordinated operation of the matching of each mechanism in the rope winding process, rope picking process and rope threading process, the precision of the matching of each mechanism is improved, and the fully automated process of paracord sorting is realized. In particular, after the motor is combined with the support of the automation system, the efficiency and accuracy of rope threading can be further improved, thereby realizing batch rope threading operation.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Please see Figure 2 , Figure 4 and Figure 5 The present invention provides a mechanized parachute cord threading device suitable for parachute cord management. The specific structure of the mechanized parachute cord threading device is as follows:

[0036] The parachute mechanized rope threading device has a symmetrical structure and includes: an upper base, a lower base, a rope guide clamp 4, a rope winding frame, a rope claw frame, and a rope fixing frame 9.

[0037] The upper base has a longitudinal guide rail 6 and a transverse guide rail 5 on it; the lower base is parallel to the lower part of the upper base; the rope guide clamp 4 has its upper end slidably mounted in the transverse guide rail 5 to move longitudinally and laterally on the upper base, and its free end is equipped with a rope clamp; the rope winding frame is arranged in two parallel groups on both sides of the transverse side of the lower base, and has several rope winding forks evenly arranged on it; the rope claw frame is arranged in two parallel groups on both sides of the transverse side of the lower base, between the two groups of rope winding frames, and connected to the upper base, and has several rope claws at its end, which match the rope winding forks to restrict the rope bundle on the rope winding forks to the middle of the rope claws; the rope fixing frame 9 is arranged in two parallel groups on both sides of the transverse side of the lower base, away from the rope claw frame, and has several hooks on it, which match the rope claws of the rope claw frame to pass through the middle of the rope claw frame to remove and fix the rope bundle.

[0038] The transverse guide rail 5 and the longitudinal guide rail 6 are vertically slidably arranged on a working surface. The longitudinal guide rail 6 is connected to the upper base, and there is at least one longitudinal guide rail, which enables the guide rope clamp 4 to move back and forth and left and right between the lower base and the lower base, thereby guiding and adjusting the position of the paracord. For example, if there are two longitudinal guide rails 6, they are distributed on both sides of the transverse side of the upper base, and the two ends of the transverse guide rail 5 are respectively slidably arranged on the two longitudinal guide rails.

[0039] Preferably, each group of rope winding frames has two rows of rope winding forks, with the rope winding forks on the two rows arranged alternately so that the distance between each pair of matched rope winding forks and the rope claw is equal. For example... Figure 2 As shown, each group of rope winding frames includes a row of rope winding frames 2 and a row of rope winding frames 3, and the distance between adjacent rope winding forks is the same as the distance between adjacent parasol rope loops 1.

[0040] Preferably, each set of rope claws includes two rows of rope claws, with the rope claws on the two rows arranged alternately, so that the distance between two adjacent rope claws on each row is twice the distance between two adjacent rope loops on the umbrella bag to be threaded. The lower ends of the first row of rope claws 7 and the second row of rope claws 8 are provided with multiple rope claws, with the two sets of rope claws arranged alternately. For example... Figure 4 As shown, the longitudinal distance between each row of rope claws 7 and the adjacent row of rope claws 8 is consistent with the spacing between adjacent parachute rope loops 1. The spacing between adjacent rope claws in the same row is twice the spacing between adjacent parachute rope loops 1. In this embodiment, the row of rope claws 7 is located on the outer side of the row of rope claws 8 in the lateral direction.

[0041] Preferably, the rope claw on the rope claw frame includes a fixed claw and a movable claw, with a slot in the middle; the movable claw is located above the fixed claw so that the rope bundle on the rope fork in the rope winding frame is confined in the slot by the opening and closing of the movable claw. Figure 4 As shown, the ends of both the I-row rope claw 7 and the II-row rope claw 8 include a fixed claw and a movable claw, with a slot in the middle. The movable claw is located diagonally above the fixed claw, which facilitates the opening and closing of the rope claw. During operation, the rope bundle is confined in the clamping cavity between the movable claw and the fixed claw.

[0042] Preferably, the cable claw frame is slidably connected to the upper base, driving the cable claw to move in the longitudinal and transverse directions of the upper base. The main body of the cable claw frame includes a telescopic structure to drive the cable claw to move between the upper base and the lower base. For example, a hydraulic rod is provided on the main body of the cable claw frame, perpendicular to the upper and lower bases, to drive the cable claw to move between the upper and lower bases.

[0043] Preferably, the distance between the two sets of rope winding frames does not exceed the width of the transverse guide rail.

[0044] Preferably, the rope fixing frame includes a structure with a number of telescopic rods matching the number of hooks, with the hooks located at the ends of the telescopic rods. For example... Figure 5 As shown, the rope fixing frame 9 includes several rope fixing forks, each including a telescopic rod. The end of the telescopic rod is provided with a hook, which matches the slots of the two rows of rope claws 7 and 8, so that the rope bundle can be removed and fixed by passing through the middle of the rope claws when threading the rope.

[0045] Preferably, the number of rope forks on each group of rope winding frames is equal to the number of rope claws on each group of rope claw frames, so that the rope forks and rope claws are matched one-to-one.

[0046] Preferably, the number of hooks on each group of rope fixing frames is equal to the number of rope claws on each group of rope claw frames, so that the hooks and rope claws correspond one-to-one and the spacing between adjacent rope fixing forks is consistent with the spacing of the parachute rope loop 1.

[0047] For example, in this embodiment, the number of rope forks in both the first row of rope winding frame 2 and the second group of rope winding frame 3 is 6 pairs, the number of rope claws in both the first row of rope claws 7 and the second row of rope claws 8 is 6 pairs, the number of rope fixing forks in the rope fixing module 9 and the number of parachute rope loops 1 are 12 pairs. It can be understood that in other embodiments, the number of rope winding forks, rope claws and rope fixing forks can be increased or decreased according to actual needs.

[0048] Preferably, the main body of the guide rope clamp is a telescopic structure, with the rope clamp located at the end of the telescopic structure to move the rope clamp between the upper base and the lower base. For example, the part of the guide rope clamp that connects to the rope clamp is a hydraulic rod.

[0049] Preferably, the device includes a motor electrically connected to the rope winding frame, the rope guide frame, the rope claw frame, and the rope fixing frame, respectively, for driving the rope winding frame to move in the lateral direction of the lower base, driving the rope guide frame to move in the longitudinal and lateral directions of the upper base, driving the rope claw frame to move in the longitudinal direction of the upper base and / or in the lateral direction of the upper base, and driving the rope fixing frame to move electrically in the lateral direction of the lower base.

[0050] Preferably, the motor is controlled and driven by the control system to realize the fully automated process of rope threading, and can further improve the efficiency and accuracy of rope threading, thereby realizing batch rope threading operations.

[0051] Please see Figure 1 The parachute pack is in the following state after the parachute rope threading process is performed by the aforementioned mechanized parachute rope threading device: Figure 1 As shown. Please refer to [the original text]. Figure 6 The working process of the mechanized parachute rope threading device mainly includes the following steps:

[0052] The rope winding process includes step S1, combined with Figure 2 and Figure 3 As shown, it includes the following:

[0053] S1: Arrange the paracords to be even and free of tangles; perform preliminary pre-winding of the cord bundle: clamp one end of the cord bundle with the guide clamp 4 and move it to the front of the two sets of cord winding frames. The guide clamp 4, with the help of the transverse guide rail 5, moves the paracord to the left and then moves back a short distance, turning the cord bundle at the corresponding left cord winding fork; then the guide clamp 4, with the help of the transverse guide rail 5, moves the paracord to the right and then moves back a short distance, turning the cord bundle at the corresponding right cord winding fork; repeat this process until, according to the number of cord loops 1 in the paracord pack, the cord bundle is wrapped around the corresponding number of cord winding forks on both sides, and the pre-wound cord bundle is in a continuous "S" shape with consistent spacing. The two sets of rope claws are moved to the top of the two sets of rope winding frames. The longitudinal position of the rope claws is adjusted so that, from front to back, the rope claws 7 in row I correspond one-to-one with the rope winding forks (the 1st, 3rd, 5th, 7th, 9th, and 11th pairs of rope winding forks on the left and right sides) of the rope winding frame 2 in row I, and the rope claws 8 in row II correspond one-to-one with the rope winding forks (the 2nd, 4th, 6th, 8th, 10th, and 12th pairs of rope winding forks on the left and right sides) of the rope winding frame 3 in row II.

[0054] The rope-removal process includes step S2, combined with... Figure 4 As shown, it includes the following:

[0055] S2: The first row of rope winding frames 2 and the second row of rope winding frames 3 move laterally until the first row of rope winding frames 2 is below the first row of rope claws 7, and the second row of rope winding frames 3 is below the second row of rope claws 8. The first row of rope claws 7 lowers, the movable claws open, and move laterally through the middle of each rope winding fork of the first row of rope winding frames 2, closing downwards to clamp the rope bundle; at the same time, the second row of rope claws 8 lowers, the movable claws open, and move laterally through the middle of each rope winding fork of the second row of rope winding frames 3, closing downwards to clamp the rope bundle. Then, the two rows of rope claws 7 and 8 are raised upwards, clamping the rope bundle and moving it above the parachute rope loop 1.

[0056] The rope-threading process includes steps S3, S4, and S5, combined with... Figure 5 As shown, it includes the following:

[0057] S3: The two rows of rope claws 7 and 8 move longitudinally until the first pair of rope claws on the front side of row I is aligned with the first pair of parachute rope loops 1. The rope fixing frame 9 moves longitudinally until the first pair of rope fixing forks, the first pair of row I rope claws 7, and the first pair of parachute rope loops 1 are in the same longitudinal position. After row I rope claws 7 and row II rope claws 8 are in place, from front to back, row I rope claws 7 correspond to the 1st, 3rd, 5th, 7th, 9th, and 11th pairs of rope loops (row I rope loops) on the left and right sides, respectively, and row II rope claws 8 correspond to the 2nd, 4th, 6th, 8th, 10th, and 12th pairs of rope loops (row II rope loops), respectively. Row I rope claws 7 and row II rope claws 8 move laterally to adjust to the lateral position specified in the rope threading process.

[0058] S4: The first row of rope claws 7 descends, moves laterally, and clamps the rope bundle through the 1st, 3rd, 5th, 7th, 9th, and 11th pairs of rope loops (the first row of rope loops) on both sides. During this process, each movable claw opens upward to spread the parachute rope loop 1, and the first row of rope claws 7 pushes the rope bundle into the parachute rope loop 1. Adjust the lateral position of the rope fixing frame 9 until the rope fixing fork is directly above the center of each parachute rope loop 1. From front to back, the 1st, 3rd, 5th, 7th, 9th, and 11th rope fixing forks of the rope fixing frames 9 on both sides descend to fix the rope bundles inserted into the parachute rope loop 1. Then, the first row of rope claws 7 retracts from the rope loop and lifts upward, moving out of the working area. This completes the rope threading operation of the first row of rope loops on both sides, and the second row of rope claws 8 is ready to thread the rope.

[0059] S5: The second row of rope claws 8 extends downwards, moves laterally, and clamps the rope bundle through the 2nd, 4th, 6th, 8th, 10th, and 12th pairs of rope loops (Group II rope loops) on both sides. Each movable claw opens upwards to spread the parachute rope loop 1. The second row of rope claws 8 pushes the rope bundle into the parachute rope loop 1. The 2nd, 4th, 6th, 8th, 10th, and 12th rope securing forks of the rope securing frames 9 on both sides extend downwards. After completing the fixation of the rope bundle, the second row of rope claws 8 exits the rope loop and lifts upwards, moving out of the working area. This completes the rope threading operation for all parachute rope loops 1 on both sides. All rope securing forks rise upwards to reset, and the rope securing frames 9 are removed from the working area.
