DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] like Figure 1-2 As shown, an unpacked parachute bag model diagram and a packed parachute bag model diagram are exemplified. The parachute bag includes a bag cover 101, a bag safety rope loop 102 and a safety pin 104. The packing of the parachute bag is completed by gathering the bag cover 101 to overlap the bag cover holes thereon, then passing the bag safety rope loop 102 from below the adjacent bag cover holes, and after the bag safety rope loop 102 is exposed above the bag cover, the safety pin 104 is inserted into the bag safety rope loop 102.

[0038] As mentioned above, the manual packing process is inefficient, and since the parachute bag is a flexible object, there may be certain differences in the local thickness and flatness of the parachute bag, which is more difficult to clamp than a rigid object. It is difficult to meet the packing requirements by simply using mechanical clamping. To solve the above problems, the present invention provides a mechanized auxiliary packing device for a parachute bag, which is used to assist manual completion of parachute bag packing.

[0039] See also Figure 3 , provides a parachute bag mechanized auxiliary packing device, comprising:

[0040] Workbench 207;

[0041] The opening box 203 is arranged in the central area of ​​the workbench 207, with the opening facing upward, and is used to accommodate the parachute bag to achieve the initial positioning of the parachute bag;

[0042] Two guide ropes, after one end of the guide rope is looped around the distant parachute pack safety rope loop, the guide ropes are sequentially passed through two parachute pack cover plate holes (the left parachute pack cover plate hole and the right parachute pack cover plate hole) adjacent to the parachute pack safety rope loop, so as to be used to pull the parachute pack safety rope loop through the parachute pack cover plate holes and out from under the parachute pack cover plate by pulling the guide ropes;

[0043] Six wire pullers 201 are arranged on the workbench 207 around the outer periphery of the open box 203, including two guide rope wire pullers and four cover plate wire pullers; the two guide rope wire pullers are symmetrically distributed with respect to the open box and located on the same straight line, and are synchronously located on the connection line between the two parachute bag safety rope loops of the parachute bag when packing the parachute bag, respectively, to two extension lines outside the open box, for pulling the guide rope; the four cover plate wire pullers are symmetrically and evenly distributed on the work plane with respect to the center line of the workbench 207, and are divided into two groups, the two cover plate wire pullers of each group are symmetrically distributed with respect to the open box and located on the same straight line, the straight line connecting the two cover plate wire pullers of each group is perpendicular to the straight line connecting the two guide rope wire pullers of each group, and are used to pull the parachute bag cover plate to tighten;

[0044] The two guide rope pullers are equipped with two guide rope clamps, one end of the guide rope clamp is fixedly connected to the guide rope puller, and the other end is used to clamp the other end of the guide rope to pull the parachute pack safety rope loop through the parachute pack cover hole from the bottom of the parachute pack cover to the top of the parachute pack cover; the four cover plate pullers are equipped with four cover plate clamps, one end of the cover plate clamp is fixedly connected to the cover plate puller, and the other end is used to clamp the parachute pack cover to tighten the parachute pack cover.

[0045] according to Figure 3 The working process of the exemplary packing device is as follows: two of the four cover plate pullers alternately clamp the two adjacent umbrella cover plates, and the other two use the same clamping method; the guide rope puller connects the farther umbrella safety rope loop on the parachute bag through the guide rope, and the two guide rope pullers are used to fix the two guide ropes through the corresponding two guide rope clamps. Therefore, after the umbrella cover is pulled by the cover plate puller until the umbrella cover hole overlaps, the guide rope is pulled by the two guide rope pullers to drive the two umbrella safety rope loops on the parachute bag to pass through the umbrella cover hole, and then pulled from the bottom of the umbrella cover to the top of the umbrella cover, and then the safety pin is inserted to complete the packing.

[0046] For example, if the parachute bag is relatively large, n rows of parallel bag cover holes are respectively provided on the two bag cover plates, and 2n bag safety rope loops are correspondingly provided, through 2n guide ropes, (2n+2m) wire pullers and (2n+2m) matching clamps; wherein the (2n+2m) wire pullers include 2n guide rope wire pullers and 2m cover plate wire pullers, and the (2n+2m) clamps include 2n guide rope clamps and 2m cover plate clamps, and the value of n is 1 or 2, and the value of m is 1, 2 or 3; wherein the 2n guide rope wire pullers are divided into n groups, and the two guide rope wire pullers in each group are symmetrically arranged about the opening box. The 2m cover plate pullers are arranged and located on the same straight line, and the straight lines connecting the two guide rope pullers in each group are parallel to each other; among them, the 2m cover plate pullers are divided into m groups, and the two cover plate pullers in each group are symmetrically distributed about the open box and located on the same straight line, and the straight line connecting the two cover plate pullers in each group is perpendicular to the straight line connecting the two guide rope pullers in each group; thus, after the parachute bag cover is pulled to the n rows of overlapping bag cover holes by the cover plate puller, the fixedly connected guide rope is pulled by the guide rope puller until the bag safety rope loop passes through the bag cover hole and is pulled from the bottom of the bag cover to the top of the bag cover, and finally the safety pin is inserted into the bag safety rope loop to complete the packing.

[0047] In this embodiment, the layout position of the cover cable puller is adjusted so that the parachute cover is pulled as evenly as possible. If there are four cover cable pullers and cover clamps in the parachute auxiliary packing device, they are distributed on the four extension lines of the diagonal of the opening box, and the two cover clamps close to the parachute safety rope loops alternately clamp the two parachute cover plates, so that the parachute cover plates are pulled as evenly as possible.

[0048] In this embodiment, the number of the parachute pack packing wire pullers 201 is 6. It can be understood that in other embodiments, the number of wire pullers 201 can be increased or decreased according to actual needs, and their layout can also be adjusted according to actual needs. For example, if the parachute pack is small in size, 4 packing wire pullers 201 can be selected, including two guide rope wire pullers and two cover board wire pullers, and the two cover board wire pullers clamp the two parachute pack cover boards of the two parachute packs through two cover board clamps respectively.

[0049] In this embodiment, the wire puller includes: a guide assembly, a power assembly, a fixed pulley assembly and a pull rope; the power assembly is arranged inside the guide assembly, and the degree of freedom of the power assembly is limited by the internal space of the guide assembly, so that the power assembly can only move in one dimension within the guide assembly space; the fixed pulley assembly is fixed on the top plate of the guide assembly; the pull rope passes through the fixed pulley assembly and one end of the pull rope is fixed to the power assembly, so that the pull rope is pulled under the movement of the power assembly, and the other end of the pull rope is fixedly connected to the chuck, so that the wire puller moves the part clamped by the chuck toward the direction of the wire puller through the pull rope.

[0050] See also Figure 4The guide assembly includes a linear guide shaft 304, a wire puller top plate 306 and a wire puller bottom plate 301. Both ends of the linear guide shaft 304 are fixed on the wire puller top plate 306 and the wire puller bottom plate 301 to provide rigid support for the movement of the power assembly; the wire puller bottom plate 301 and the wire puller top plate 306 are fixed, and a number of linear guide shafts 304 are used to ensure that the power assembly has only one degree of freedom and can only move up and down between the wire puller top plate 306 and the wire puller bottom plate 301. The power assembly includes a cylinder 302 and a cable puller plate 303, wherein the cable puller plate 303 is sleeved on a plurality of linear guide shafts 304 and is kept in relative sliding connection with the plurality of linear guide shafts 304, the cylinder body of the cylinder 302 is fixed on the cable puller bottom plate 301, and the piston of the cylinder 302 is fixed on the cable puller plate 303, so that the cable puller plate 303 moves up and down between the cable puller top plate 306 and the cable puller bottom plate 301, and the cylinder stroke of the cable puller is selected according to the type of umbrella bag and its packing requirements. The fixed pulley assembly is fixed to the cable puller top plate 306 by bolts, and is used to change the moving direction of the pull rope 307. The pull rope 307 passes through the fixed pulley assembly and the cable puller top plate 306, one end of which is fixed on the cable puller plate 303, and the other end is fixed on the matching chuck. The contraction of the cylinder 302 drives the pull plate 303 to move, realizing the cable pulling operation.

[0051] See also Figure 5 and Figure 7 The chucks are divided into a cover plate chuck 202 and a guide rope chuck 206, both of which adopt the eccentric clamp principle. The structures of the two chucks are composed of a pressure tongue, a pressure seat and a latch. The pressure tongue and the pressure seat are connected together by a latch and rotate around the latch to form an eccentric wheel structure; there is a protrusion at the end of the pressure tongue, which will form a self-locking after clamping the object. Please refer to the clamping process and self-locking principle Figure 6 and Figure 8 The protrusion at the end of the chuck tongue moves as the tongue rotates around the latch. When the tongue rotates, its protrusion contacts the clamped object. Under the action of friction, when the clamped object tends to move away from the chuck, Figure 6 and Figure 8 The clamped object tends to move to the left, which will cause the tongue depressor to rotate clockwise, and the clamp will become tighter and tighter, forming a self-locking effect.

[0052] For example, the guide rope clamp 206 includes a guide rope clamp pressing tongue 401 , a guide rope clamp pressing seat 403 and a guide rope clamp pin 402 , and the guide rope clamp pressing tongue 401 and the guide rope clamp pressing seat 403 are connected together through the guide rope clamp pin 402 .

[0053] The structures of the cover plate clamp 202 and the guide rope clamp 206 are slightly different because of the different clamping objects. Specifically, the clamp width of the cover plate clamp 202 is wider than that of the guide rope clamp 206, and is used to clamp objects with a larger area; the two sides of the pressure seat of the guide rope clamp 206 are provided with limiting structures to prevent the guide rope from loosening from both sides; the force arm of the cover plate clamp 202 is longer than that of the guide rope clamp 206 (that is, the distance from the end away from the pressure tongue and the end away from the pressure seat to the clamp pin is longer), so that the cover plate clamp 202 is more labor-saving when clamping the cover plate.

[0054] Based on the above-mentioned mechanized auxiliary packing device for parachute bag, the necessary link of using auxiliary pins for manual packing is omitted, and the bag cover 101 is directly pulled by a mechanical device to send the two bag cover plates 101 to a predetermined position, and then the bag safety rope ring 102 is pulled through the two bag cover plate holes to insert the safety pin 104. Because the bag is a flexible object, it needs to be limited in force during the clamping process to prevent the bag from loosening. The tension provided by the cylinder is used to achieve flexible assistance and limited force retention to ensure successful bag packing.

[0055] Based on the novel parachute bag packing device of the above-mentioned embodiment, the novel parachute bag packing device is used to assist manual packing, including the following steps:

[0056] (1) Place the parachute bag into the open box of the auxiliary packing device; clamp the two pieces of bag cover plates with the cover plate clamps of each group; pass the guide rope of each group from the outside to the inside of the two distant bag cover plate holes in turn, connect them to the distant bag safety rope loops, and clamp the guide rope with the guide rope clamp. The specific process can be achieved by manual operation or using a corresponding automatic threading device.

[0057] (2) Based on the auxiliary packing device of the present invention, the cover plate clamp is first pulled by the cover plate puller until the umbrella cover plate holes overlap and are maintained with limited force; then the guide rope clamp is pulled by the guide rope puller until the umbrella cover plate safety rope loop passes through the umbrella cover plate hole, and is pulled from the bottom of the umbrella cover plate to the top of the umbrella cover plate, and is maintained with limited force.

[0058] (3) Insert the safety pin into the safety rope loop of the parachute bag, loosen the cover plate clamp and the guide rope clamp, remove the guide rope, and complete the packing of the parachute bag.

[0059] In this embodiment, in step (1), when there are four cover wire pullers and four cover clamps, the cover wire pullers are arranged on four extension lines of two diagonals of the opening box, and the two cover clamps in each group respectively clamp the umbrella bag cover away from one side.

[0060] See also Figure 3 and Fig. 9 , based on Figure 3The device shown provides a parachute bag packing device. Packing a parachute bag mainly includes the following steps:

[0061] Process 1 includes step S1 and step S2:

[0062] (1) The parachute is manually placed in the parachute bag and placed in the open box 203. The cover plate clamps 202 located at the four corners clamp one corner of the parachute bag cover plate on the opposite side respectively.

[0063] (2) The guide rope 205 passes through the parachute pack safety rope loop and the two parachute pack cover plate holes, and is clamped with the guide rope clamp 206.

[0064] Process 2 includes step S3 and step S4:

[0065] (3) The cable pullers 201 at the four corners pull the cover plate clamps 202 to move the umbrella cover plate 101 into position, ensuring that the two cover plate holes overlap and maintaining the limit force;

[0066] (4) The two pullers 201 located at the center line pull the guide rope clamp 206 to allow the safety rope to pass through the two umbrella cover plate holes and maintain it with limited force.

[0067] Process 3 includes step S5:

[0068] (5) Manually insert the safety pin, loosen all the clamps, remove the guide rope 205, check the packing status of the parachute bag, and finish packing after confirming that it is correct.
