Detailed Description

Embodiments of the elastic loop encasement system of the present invention are further described below with reference to the drawings.

The preferred embodiment of the elastic ring packing system of the present invention, as shown in fig. 1 and 2, comprises a clip loading device for transporting a workpiece, an elastic ring loading device for transporting an elastic ring 4, and an elastic ring packing device for packing the elastic ring 4 on the workpiece, wherein the clip loading device, the elastic ring loading device, and the elastic ring packing device are all disposed on an operation table 6.

In this embodiment, a feeding process of the clip feeding device is described by taking a taper pipe formed by two clips in an involutive manner as an example, the clip feeding device includes a clip vibrating and conveying disk fixed on the operating table 6, and since the taper pipe in this embodiment is formed by two clips in an involutive manner, two clip vibrating and conveying disks need to be arranged to respectively vibrate and convey two clips, and a specific clip vibrating and conveying disk is a first vibrating and conveying disk 1 and a second vibrating and conveying disk 2.

The first vibration disk 1 and the second vibration disk 2 have the same structure, and the following description will be given by taking the first vibration disk 1 as an example only, and the first vibration disk 1 is provided with a spiral vibration feeding track which is used for supporting the clamping piece 5 and driving the clamping piece 5 to move forward and spirally rise under the vibration effect. As shown in fig. 12, which is a partial structure diagram of the first vibration plate 1, the vibration feeding rails include a horizontal clip feeding rail and a vertical clip feeding rail, the horizontal clip feeding rail includes a supporting wall 407 and a side wall 404, in order to form a good supporting and limiting effect on the clips, the supporting wall 407 is provided with a continuous supporting and limiting structure, the supporting and limiting structure in this embodiment is a supporting and limiting groove 401 formed on the supporting wall 407, the supporting and limiting groove 401 is V-shaped, and can support and limit the outer conical surface of the clip, so as to ensure that the clip can be smoothly conveyed forward, so that the clip is not easily shaken off, the clamping pieces which are not supported by the supporting and limiting grooves 401 are easy to shake off the track and fall into the vibration disc again, and the extending directions of the supporting and limiting groove 401 and the supporting wall 407 are consistent, so that the large head end or the small head end of the clip can move forward.

Along the moving direction of the clamping piece 5, a blocking plate 402, a transition beam 403, a fixed baffle 405, a movable baffle 409 and a groove 406 are sequentially arranged on the horizontal clamping piece feeding track, wherein one end of the blocking plate 402 is fixed on a side wall 404, the other end of the blocking plate is suspended, the blocking plate 402 is horizontally arranged, and the distance from the blocking plate 402 to a supporting wall 407 is smaller than the length of the clamping piece, so that the vertical clamping piece cannot pass through the blocking plate 402 and can only be blocked by the blocking plate 402 and fall into a vibration disc, as shown in fig. 20, or is blocked and falls into a horizontal posture, and the horizontal clamping piece can continue to be conveyed forwards through the blocking plate 402. Thus, the vertical clamping pieces are rejected, or the horizontal clamping pieces are screened out.

A transition beam 403 is arranged downstream of the stop plate 402, the transition beam 403 is part of a support wall 407, the width of the transition beam is smaller than the groove width of the clip groove, corresponding to a section of narrower support wall, and the length of the transition beam 403 is greater than the clip length L, so that when the clip with the upward internal thread passes through the transition beam 403, it can be supported and transported further by the support and limit groove 401, as shown in fig. 12. The clip with the downward internal thread initially "rides" on the transition beam 403 as it passes over the transition beam 403, but is easily rotated around the transition beam 403 by vibration to slide off as shown in fig. 20. Even if there are individual clips that "ride" smoothly on the transition beam 403, they will collide with the end surface of the next section of support wall (i.e., stop surface 408) and fall out as the forward motion continues. Thus, the clamping piece with the upward internal thread is screened out.

One end of the fixed baffle 405 is fixed on the side wall 404, the other end of the fixed baffle is suspended, the movable baffle 409 is installed on the fixed baffle 405 in a vertically guiding and moving manner, and a guide hole for the movable baffle 409 to vertically guide and move is formed in the fixed baffle 405. As shown in fig. 21, a matching form of the fixed baffle and the movable baffle is shown, a guide hole on the fixed baffle 405 is a blind hole with a downward hole opening, a spring 415 is arranged between a hole bottom of the guide hole and the movable baffle 409, one end of the spring 415 is fixed on the hole bottom of the guide hole, the other end of the spring 415 is fixed on the movable baffle 409, the movable baffle 409 is equivalently hung on the fixed baffle 405 through the spring 415, and when the movable baffle 409 is subjected to an upward acting force, the spring 415 can be compressed to move upwards.

The movable baffle 409 comprises a material facing surface 4091 which is obliquely arranged facing the material feeding direction, and before the material is fed, the distance between the bottom end of the material facing surface 4091 and the supporting wall 407 is smaller than the height h of the big head end of the clamping piece, so that when the big head end of the clamping piece faces forwards, the big head end is higher and can abut against the material facing surface 4091 which is obliquely arranged, and then the clamping piece is guided to slide off the feeding track under the vibration effect. Meanwhile, the distance between the bottom end of the material facing surface 4091 and the supporting wall 407 is greater than the height of the small head end of the clip, so that when the clip with the small head end facing forward is fed, the small head end is lower and can be drilled below the moving baffle 409, and the section of the clip is in an inclined state when the clip lies flat, so that as the clip continues to move forward, the section of the clip can apply an upward acting force to the moving baffle 409 to force the moving baffle 409 to compress the spring 415 to move upward, and finally the clip can pass through the moving baffle 409 and then reset under the reaction force of the spring by the moving baffle 409.

In addition, the side of the fixed baffle 405 facing the material feeding direction is the inclined surface 4051, the inclined surface 4051 is parallel to the material feeding surface 4091, and a set distance is provided between the fixed baffle 405 and the supporting wall 407, so that a part of the clips with big head ends facing forward and two cross sections not at the same height, that is, the clips with two cross sections higher and lower and the whole higher of the big head ends directly abut against the inclined surface 4051 and are guided down by the inclined surface 4051 without being guided down by the movable baffle 409.

The inclined surface 4051 is equivalent to share a part of the responsibility of the movable baffle 409, so that the height of the fixed baffle 405 is not too high, which means that the length of the movable baffle 409 is not too long, otherwise, if the clip is stopped by only the movable baffle 409, the fixed baffle 405 needs to be set to be higher, and then the movable baffle 409 needs to be set to be longer, which causes the weight of the movable baffle 409 to be increased, is not favorable for the upward movement of the movable baffle 409, and even causes the situation that the clip cannot jack the clip.

With the vibration disk itself as a reference object, the clips move forward, and then the vertical clip feeding track is arranged on the right side of the horizontal clip feeding track and parallel to the horizontal clip feeding track, as shown in fig. 19, the vertical clip feeding track includes a supporting surface 413 for supporting the end surface of the big end of the clip, and two limiting side walls perpendicular to the supporting surface 413 for preventing the vertical clip from rotating, the two limiting side walls are an inner limiting side wall 412 and an outer limiting side wall 411, respectively, and the distance between the inner limiting side wall 412 and the outer limiting side wall 411 matches with the height of the big end of the clip.

The groove 406 is provided at the end of the horizontal clip feed track, as shown in fig. 13, and the groove 406 includes a bottom support wall 4061 for supporting the big end of the clip and a side support wall 4062 for supporting the outer conical surface of the clip. The length of the groove 406 is less than the length L of the clip 12, and the front and rear sides of the groove 406 are both provided with the support limiting grooves 401, so as shown in fig. 14, when the clip with the small head end facing forward moves to the position of the groove 406, the small head end of the clip can cross over the groove 406 because the gravity center of the clip is back, and at a certain moment, the clip straddles over the groove, and the large head end and the small head end of the clip are both supported on the support limiting grooves 401.

As shown in fig. 15, as the clip continues to move forward, the big end of the clip will overhang the groove, and because the center of gravity is unstable, the big end of the clip will fall into the groove and be inclined, and at this time, the big end of the clip is supported by the bottom support wall 4061, and the outer conical surface of the clip is supported by the side support walls 4062. The recess 406 also includes a stop wall 4063 opposite the side support wall 4062, the stop wall 4063 stopping the large head end of the clip.

The bottom support wall 4061 is gradually inclined from top to bottom toward the support surface 413 and is connected to the support surface 413 such that the clip falling into the recess slides down the bottom support wall 4061 under its own weight. As shown in fig. 13, a transition guide wall 414 is disposed between the inner limiting sidewall 412 and the side support wall 4062, and the transition guide wall 414 is an arc-shaped wall and can guide the downward-sliding clip to transition to the support surface 413, which is equivalent to guiding the clip to turn as shown in fig. 12.

The outer limit side wall 411 and the stop wall 4063 are also in arc transition, so that the clip can be favorably transited to the supporting surface 413, and in order to prevent the clip from falling off the vertical clip feeding track in the process of transiting to the supporting surface 413, an upturned edge 410 which is turned upwards is arranged at the top of the outer limit side wall 411 opposite to the transition guide wall 414, the upturned edge 410 extends towards the groove and is in an arc shape, and the upturned edge 410 and the transition guide wall 414 are matched with each other, so that the large head end of the clip can be prevented from falling off the vertical clip feeding track in the turning process, as shown in fig. 16 and 17.
