Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile equipment, in particular to a double positioning and flexible buffer plug-in mechanism of a storage tray. BACKGROUND

[0002] In the automatic production of computerized embroidery machines, the bobbin case (with a bobbin core inside) is a key component that carries the bottom thread, and needs to be replaced when the bottom thread is used up. In order to improve production efficiency, instead of traditional manual operation, the skilled person in the art has been committed to researching and developing various mechanical devices for automatically replacing bobbin cases (or bobbin cores).

[0003] At present, such automatic devices usually include a storage tray for storing and supplying spare bobbin cases, and a mechanical swing arm that performs the action of grabbing and installing. During work, the swing arm needs to insert the bobbin case into a specific plug-in position on the storage tray at high speed and accurately, in order to complete the picking up or returning of the bobbin case.

[0004] However, the existing technical solutions still have significant defects in actual application. Due to the inevitable vibration of the equipment during high-speed operation, combined with the small tolerances existing in the manufacturing and assembly links, it is difficult for the swing arm to always keep perfect centration between the bobbin case and the plug-in position of the storage tray. This small deviation in centration will cause a series of problems at the moment of high-speed plugging: first, rigid impact between the bobbin case and the storage tray may occur, producing noise and causing component wear, affecting the service life of the equipment; second, it is easy to cause the bobbin case to not be plugged in place, causing the subsequent process to be unable to proceed normally, and even causing the mechanism to jam and other faults; more seriously, the precise pins on the bobbin case for positioning and fixing are extremely easy to bend or break under the impact of non-centration, thus causing the entire bobbin case to be scrapped, increasing production cost and maintenance frequency.

[0005] Therefore, there is a lack of a storage tray plug-in mechanism in the prior art that can effectively compensate for the deviation in centration during high-speed motion, and has the functions of precise positioning and flexible buffering, which has become a technical bottleneck restricting the further improvement of the reliability, efficiency and economy of the automatic bobbin changing system of computerized embroidery machines.

[0011] Preferably, the reset disc is provided with upper deformation openings and lower deformation openings distributed along the circumferential direction, the upper deformation openings penetrate the upper ball grooves along the radial direction of the reset disc, and the lower deformation openings penetrate the lower ball grooves along the radial direction of the reset disc.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means and achieved specific purposes and functions of the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0031] As Figures 1-3 shown, a double positioning and flexible buffering plug-in mechanism of a storage tray, comprising: a storage turntable 1, a mounting groove 11 being distributed along the circumferential surface of the storage turntable 1, each mounting groove 11 extending along the radial direction of the storage turntable 1; a storage shaft 2, disposed outside the storage turntable 1 and capable of sliding along the radial direction of the mounting groove 11; one end of the storage shaft 2 forms a reset end 21 extending into the mounting groove 11, the reset end 21 being provided with a tapered groove 211, and the other end of the storage shaft 2 being provided with a circular head 22 for butt joint with a shuttle shell pin; an elastic reset mechanism, disposed in the mounting groove 11, having a reset rod 31, the reset rod 31 being capable of elastically abutting in the tapered groove 211 along the axial direction of the storage shaft 2; wherein, when the storage shaft 2 is plugged with the shuttle shell, if there is an alignment error, the position is automatically adjusted by moving along the radial direction of the mounting groove 11.

[0032] The double positioning and flexible buffer plug-in mechanism of the storage tray comprises a storage turntable 1, a storage shaft 2 and an elastic reset mechanism. A plurality of groups of installation grooves 11 are arranged on the circumferential surface of the storage turntable 1 in the circumferential direction, and each installation groove 11 extends in the radial direction of the storage turntable 1. The storage shaft 2 is arranged outside the storage turntable 1 and can slide in the radial direction of the installation groove 11; one end of the storage shaft 2 forms a reset end 21 extending into the installation groove 11, and a tapered groove 211 is arranged on the reset end 21; the other end of the storage shaft 2 is provided with a circular head 22 used for butt joint with the shuttle shell pin, and the circular head 22 has a circular guide surface to provide the first preliminary fault-tolerant guidance during the plug-in process. The elastic reset mechanism is arranged in the installation groove 11 and comprises a reset rod 31 which can elastically abut in the axial direction of the storage shaft 2 in the tapered groove 211 to form an elastic support for the storage shaft 2. During the plug-in process of the storage shaft 2 and the shuttle shell pin, if there is an alignment error, the circular head 22 first guides the shuttle shell pin through the circular guide surface to realize preliminary fault tolerance; when the butt joint error is further increased, the tapered groove 211 at the bottom end of the circular head 22 overcomes the elastic force of the reset rod 31 to drive the storage shaft 2 to displace in the radial direction of the installation groove 11 to realize the second self-adaptive centering positioning. After the butt joint is completed, the reset rod 31 drives the storage shaft 2 to automatically reset, thereby effectively avoiding problems such as rigid impact, incomplete plug-in and damage to the shuttle shell pin caused by alignment error during the high-speed plug-in process.

[0033] During the high-speed plug-in of the storage shaft 2 and the shuttle shell pin, the first preliminary fault-tolerant guidance is first provided by the circular guide surface of the circular head 22 of the storage shaft 2 to guide the pin to smoothly enter the butt joint area. When the butt joint error occurs, the tapered groove 211 at the bottom end of the circular head 22 is further guided to overcome the elastic force of the reset rod 31 to drive the storage shaft 2 to displace in the radial direction of the installation groove 11 to realize the second self-adaptive centering positioning, thereby ensuring the smooth plug-in process. After the butt joint is completed, the reset rod 31 drives the storage shaft 2 to automatically reset under the action of the elastic restoring force to restore the initial position and prepare for the next plug-in.

[0034] As shown in Figure 4 the installation groove 11 has an inner diameter greater than the first limiting surface 111 of the storage shaft 2, the elastic reset mechanism further comprises a second limiting surface 32 close to the first limiting surface 111, the reset end 21 of the storage shaft 2 forms a reset disc 23 which is slidingly arranged between the first limiting surface 111 and the second limiting surface 32.

[0035] Each installation groove 11 extends along the radial direction of the storage turntable 1 and has a first limiting surface 111 with a large inner diameter inside. The storage shaft 2 is arranged outside the storage turntable 1 and can slide along the radial direction of the installation groove 11; one end of the storage shaft 2 forms a reset end 21 extending into the installation groove 11, and the reset end 21 is provided with a reset disc 23 which is slidingly arranged between the first limiting surface 111 of the installation groove 11 and the second limiting surface 32 of the elastic reset mechanism, thereby forming an accurate sliding gap in the axial direction.

[0036] During the insertion of the storage shaft 2 and the shuttle shell pin, if there is an alignment error, the circular head 22 first guides the shuttle shell pin through the circular guide surface to achieve preliminary fault tolerance; when the misalignment of the interface is further increased, the tapered groove 211 at the bottom end of the circular head 22 overcomes the elastic force of the reset rod 31, drives the storage shaft 2 to move smoothly along the radial direction of the installation groove 11 between the first limiting surface 111 and the second limiting surface 32 together with the reset disc 23, and realizes the second adaptive centering positioning. After the connection is completed, the reset rod 31 drives the storage shaft 2 to automatically reset, and the reset disc 23 stably resets in the cavity formed by the limiting surfaces, thereby effectively avoiding problems such as rigid impact, incomplete insertion, and damage to the shuttle shell pin caused by alignment errors during high-speed insertion.

[0037] The reset disc 23 cooperates with the sliding cavity formed by the first limiting surface 111 and the second limiting surface 32, not only realizes the adaptive displacement of the storage shaft 2 in the radial direction, but also ensures the stability of movement and the accuracy of reset through the accurate guidance of the reset disc 23, thereby improving the overall rigidity, reliability and service life of the mechanism, and is particularly suitable for high-speed and high-precision automatic insertion scenarios.

[0038] As shown in Figures 4-10 The top end of the reset disc 23 is provided with upper ball grooves 231 distributed along the circumferential direction, and the bottom end of the reset disc 23 is provided with lower ball grooves 232 distributed along the circumferential direction, the upper ball grooves 231 are provided with upper ball bearings 233 rolling with the first limiting surface 111, and the lower ball grooves 232 are provided with lower ball bearings 234 rolling with the second limiting surface 32.

[0039] In the process of inserting the shuttle shell pin into the storage shaft 2, if there is a misalignment error, the circular head 22 first guides the shuttle shell pin through its circular guide surface to achieve preliminary fault tolerance; when the misalignment of the interface is further increased, the tapered groove 211 at the bottom of the circular head 22 overcomes the elastic force of the reset rod 31, and drives the storage shaft 2 to produce radial displacement together with the reset disc 23. At this time, the upper and lower sides of the reset disc 23 are rolled on the corresponding limiting surfaces, respectively, to convert the original sliding friction into rolling friction, ensuring that the radial self-adaptive centering process is smoother and more smooth. After the interface is connected, the reset rod 31 drives the storage shaft 2 to automatically reset, and the reset disc 23 is stably reset under the guidance of the ball, thereby effectively avoiding problems such as rigid impact, incomplete insertion, and damage to the shuttle shell pin caused by misalignment error in the high-speed insertion process.

[0040] In the process of radial self-adaptive centering of the storage shaft 2, the reset disc 23 moves between the first limiting surface 111 and the second limiting surface 32. At this time, the upper ball 233 and the lower ball 234 embedded in the upper ball groove 231 and the lower ball groove 232 of the reset disc 23 are rolled along the first limiting surface 111 and the second limiting surface 32, respectively, to efficiently convert the original sliding friction into rolling friction. This conversion ensures that the storage shaft 2 moves more quickly and smoothly when overcoming the elastic force of the reset rod 31 and producing radial displacement, thereby supporting the rapid and accurate implementation of the second self-adaptive centering. During the reset stage after the insertion action is completed, the reset disc 23 is also guided by the ball to return to the initial position stably and accurately.

[0041] As shown in Figures 4-10 , the elastic reset mechanism further includes a buffer ring 33 elastically abutting against the bottom end of the reset disc 23. The end of the buffer ring 33 away from the axis of the storage turntable 1 forms the second limiting surface 32, and the reset rod 31 passes through the buffer ring 33 and abuts against the tapered groove 211 of the storage shaft 2.

[0042] When the shuttle shell pin and the circular head 22 of the storage shaft 2 enter the final interface stage, if there is a residual axial impact, the reset disc 23 will be pressed and push the buffer ring 33. When the force of the reset disc 23 on the buffer ring 33 exceeds the pre-tightening elastic force of the buffer ring 33, the reset disc 23 will drive the entire storage shaft 2 to produce a small stable displacement along its axial direction. This process converts sharp rigid impact into controllable elastic compression, which provides a buffer for the insertion action and effectively absorbs and dissipates the impact energy.

[0043] The buffer ring 33 constitutes the third axial buffer protection after the radial self-adaptive centering. It significantly reduces the impact noise and instantaneous impact force at the end of the insertion, not only improving the quiet performance of the equipment during operation, but also essentially reducing the fatigue wear of related components caused by repeated impact.

[0044] As shown in Figure 9and Figure 10 As shown in the figure, the reset disc 23 is provided with upper deformation openings 235 and lower deformation openings 236 distributed along the circumference thereof, the upper deformation openings 235 penetrating the upper ball grooves 231 along the radial direction of the reset disc 23, and the lower deformation openings 236 penetrating the lower ball grooves 232 along the radial direction of the reset disc 23.

[0045] During the assembly process, the upper deformation openings 235 and the lower deformation openings 236 can be elastically expanded by applying radial extrusion to the reset disc 23 through a special tool, so that the opening size of the upper ball grooves 231 and the lower ball grooves 232 is temporarily increased. At this time, the upper ball 233 and the lower ball 234 can be easily and accurately inserted into the corresponding upper ball grooves 231 and lower ball grooves 232. When the external extrusion force is removed, the upper deformation openings 235 and the lower deformation openings 236 return to their original state, and the upper deformation openings 235 and the lower deformation openings 236 shrink, thereby reliably limiting the upper ball 233 and the lower ball 234 in the grooves, completing the assembly of the entire ball assembly.

[0046] As shown in the figure, Figure 4 and Figure 7 As shown in the figure, the elastic reset mechanism further includes a positioning plug 34 coaxially arranged in the mounting groove 11, the positioning plug 34 is provided with an adjusting plug 35 coaxially and threadedly connected thereto, and the reset rod 31 is coaxially and slidingly arranged in the adjusting plug 35. The top end of the reset rod 31 forms a protrusion 351 and cooperates with the tapered groove 211 of the storage shaft 2. A first elastic element 36 is arranged between the protrusion 351 and the adjusting plug 35.

[0047] Before the operation of the mechanism, the adjusting plug 35 can be rotated to make fine adjustment of the axial position of the adjusting plug 35 relative to the positioning plug 34 by using the threaded pair. This action changes the compression pre-tightening force of the first elastic element 36 on the adjusting plug 35, thereby accurately setting the initial elastic abutting force of the reset rod 31 applied to the tapered groove 211 of the storage shaft 2. When the storage shaft 2 occurs radial displacement during the insertion process, the tapered groove 211 surface will drive the protrusion 351 of the reset rod 31 to overcome the force of the first elastic element 36 and produce axial sliding, so as to realize self-adaptive centering and flexible buffering. After the insertion is completed, the restoring force of the first elastic element 36 pushes the storage shaft 2 to accurately reset through the reset rod 31. Through simple screwing operation, the elastic feedback force of the reset rod 31 can be accurately optimized for different insertion speeds, loads or wear states, so as to ensure that the self-adaptive centering and buffering reset functions are always in the best working state.

[0048] As shown in the figure, Figure 4 and Figure 7 As shown in the figure, the protrusion 351 is provided with an abutting ball 352 cooperating with the tapered groove 211 of the storage shaft 2.

[0049] When the storage shaft 2 is radially displaced due to misalignment, the inner surface of the conical groove 211 will directly act on the abutting ball 352. In this process, the sliding friction between the conical groove 211 and the abutting ball 352 is converted into the rolling friction of the ball itself. The reset lever 31 maintains continuous and smooth linear contact with the conical groove 211 through the ball while transmitting the pressure of the first elastic element 36, making the radial movement of the storage shaft 2 more smooth. The introduction of the convex head 351 into the abutting ball 352 optimizes the potential sliding friction pair between the reset lever 31 and the conical groove 211 into a highly efficient rolling friction pair. This improvement significantly reduces the frictional resistance and wear on the contact surfaces of the two, not only making the radial self-adaptive centering action of the storage shaft 2 more sensitive and smooth, eliminating the possibility of jamming caused by sliding friction, but also greatly improving the durability of the key contact pair.

[0050] As shown in Figure 4 , Figure 7 , the positioning plug 34 is threadedly connected with the installation groove 11 of the storage turntable 1, and the second elastic element 37 is arranged between the positioning plug 34 and the buffer ring 33.

[0051] During assembly, by tightening the positioning plug 34, it can be fixed in the installation groove 11 and establish the reference position of the entire elastic reset mechanism. When the reset disc 23 is pressed and pushes the buffer ring 33 for axial buffering, the buffer ring 33 will directly compress the second elastic element 37 between it and the positioning plug 34. This process is independent of the action of the first elastic element 36 of the reset lever 31 and is specifically used to absorb and buffer axial impact. After the impact ends, the restoring force of the second elastic element 37 drives the buffer ring 33 and the reset disc 23 to reset.

[0052] The threaded connection of the positioning plug 34 provides convenience for the installation and maintenance of the entire mechanism and ensures accurate initial positioning. The independent arrangement of the second elastic element 37 decouples the axial buffering function and the radial reset function. This allows the radial self-adaptive centering elastic force (provided by the first elastic element 36) and the axial buffering force (provided by the second elastic element 37) to be independently designed and optimized without interference.

[0053] As shown in Figure 9 , the storage shaft 2 includes an outer shaft body 24 and an inner shaft body 25 connected coaxially, the circular head 22 is arranged at the outer end of the outer shaft body 24, and the reset disc 23 is arranged at one end of the inner shaft body 25.

[0054] When assembling or maintaining, the total axial length of the outer shaft body 24 and the inner shaft body 25 after being screwed can be adjusted accurately. This adjustment makes the axial position of the reset disc 23 in the mounting groove 11 and the extension length of the circular head 22 outside the storage turntable 1 be accurately set. After the assembly is completed, the split storage shaft 2 operates as a rigid whole during the operation of the mechanism. The split design allows the replacement of the worn parts (such as the circular head 22) without the need to replace the entire storage shaft 2 assembly, significantly reducing maintenance costs and improving the service life and economy of the entire mechanism.

[0055] As shown in Figure 8 The positioning plug 34 is provided with a positioning polygonal cylinder 341 at one end thereof towards the axis of the storage turntable 1, and the adjusting plug 35 is provided with an adjusting polygonal cylinder 353 at one end thereof towards the storage turntable 1.

[0056] During assembly, debugging or maintenance, the operator can use the corresponding polygonal wrench tool. By rotating the positioning polygonal cylinder 341, the entire positioning plug 34 can be screwed into or out of the mounting groove 11, thereby changing the relative distance between the positioning plug 34 and the buffer ring 33, so as to independently adjust the pre-tightening force of the second elastic element 37. After setting the axial buffer force, the positioning polygonal cylinder 341 can be fixed by using the tool, and the adjusting polygonal cylinder 353 is embedded to rotate the adjusting plug 35, so as to independently and accurately adjust the pre-tightening force of the first elastic element 36 on the reset rod 31. The entire operation process is clear in sequence, and the adjustment of the first elastic element 36 and the second elastic element 37 does not interfere with each other.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
