Description

Technical Field

[0001] This utility model relates to the processing of yarn coils, and in particular to a bobbin changing device for use with coils. Background Technology

[0002] In the coiling process of yarn, the coiled yarn is typically stored in a bobbin. The rotating disc of the coiling device is located on the side of the bobbin, causing the yarn entering the bobbin to rotate and form small loops. Simultaneously, the yarn coils into larger loops in conjunction with the rotation of the bobbin. When a certain amount of yarn has accumulated in the bobbin, the bobbin needs to be replaced. Currently, bobbin replacement is generally done manually, which is inconvenient and inefficient. Utility Model Content

[0033] Please see Figure 1 and Figure 2 A sleeve changing device for use with coiled strips includes a fixed frame 1, a rotating frame 2, a first drive unit 3, three sets of fixed limit wheels 4, and three sets of movable limit wheels 5.

[0034] The fixing bracket 1 is used to fix it to the ground. More specifically, the bottom of the fixing bracket 1 can be a grounding flange. Holes are drilled in the ground and nuts are embedded. The fixing bracket 1 is fixed to the ground using bolts.

[0035] The rotating frame 2 is rotatably connected to the fixed frame 1 around a vertical axis. More specifically, the rotating frame 2 can be cylindrical and sleeved on the fixed frame 1, with the two being rotatably connected by two bearings 6.

[0036] The rotating frame 2 is also fixed with three dividing strips 2a, which are arranged in a uniform circular array. Two adjacent dividing strips 2a form a placement area 7 for the yarn bobbin to enter.

[0037] Please see Figure 3 and Figure 4The first drive unit 3 is used to drive the rotating frame 2 to rotate, so that the three placement areas 7 exchange positions in sequence. More specifically, the first drive unit 3 can be a servo motor, which is fixedly connected to the fixed frame 1 and located below the rotating frame 2; an internal gear ring 2b is fixedly connected to the bottom of the rotating frame 2, and the output shaft of the servo motor is connected to a planetary gear reducer 3a and the gears mesh with the internal gear ring 2b.

[0038] The three placement areas 7 for yarn bobbins correspond to three positions: placing an empty yarn bobbin; storing the coiled yarn in the yarn bobbin in conjunction with the coiling device; and pushing out a yarn bobbin filled with yarn. The first drive unit 3 drives the rotating frame 2 to rotate by 120 degrees each time, and each rotation causes the yarn bobbin to enter the next position sequentially from the current position.

[0039] Please see Figure 2 Three sets of fixed limiting wheels 4 are respectively installed on three dividing strips 2a. More specifically, the fixed limiting wheels 4 can rotate around the vertical axis relative to the dividing strips 2a, while the vertical axis is fixed relative to the dividing strips 2a.

[0040] Three sets of movable limit wheels 5 are respectively installed on three partition bars 2a. More specifically, the movable limit wheels 5 can rotate around a vertical axis relative to the partition bars 2a, and this vertical axis is movable relative to the partition bars 2a. The movement can be either oscillating or radial movement.

[0041] Please see Figure 2 and Figure 3 In some embodiments, an L-shaped strip 2c is radially slidably connected to the separator 2a, and a movable limiting wheel 5 is rotatably connected to the first end of the L-shaped strip 2c outside the separator 2a. That is, the movement is radial.

[0042] Each placement area 7 corresponds to a set of fixed limiting wheels 4 and a set of movable limiting wheels 5. The movable limiting wheels 5 can switch between two states: a working state where the yarn bobbin cannot move radially away from the placement area 7, and a replacement state where the yarn bobbin can move radially away from the placement area 7. A second drive unit can be provided to drive the movement of each of the three sets of movable limiting wheels 5, or a linkage assembly can be designed between the three sets of movable limiting wheels 5 and the fixed frame 1, using the relative rotation between the rotating frame 2 and the movable frame to drive the movement of the movable limiting wheels 5.

[0043] Please see Figure 5 and Figure 6In some embodiments, in conjunction with the above-described embodiment of "radial movement," the fixing frame 1 has a planar cam 1a. The second end of the L-shaped bar 2c is connected to the planar cam 1a. More specifically, the second end of the L-shaped bar 2c is rotatably connected to a guide wheel that enters the planar cam 1a. More specifically, the planar cam 1a may have a smaller diameter first segment 1a1 and a larger diameter first segment 1a1. When the guide wheel 2a1 is within the first segment 1a1, the corresponding movable limiting wheel 5 is in a working state in one position, i.e., restricting the yarn bobbin from leaving the placement area 7; when the guide wheel 2a1 is within the second segment 1a2, the corresponding movable limiting wheel 5 is in a changing state in one position, i.e., the yarn bobbin can enter / leave the placement area 7. The connection between the L-shaped bar 2c and the planar cam 1a is used to enable the movable limiting wheel 5 to be in a working state in one position and a changing state in the other two positions.

[0044] Please see Figure 3 and Figure 4 In some embodiments, in conjunction with the above-described embodiment of "fixed frame 1 having a planar cam 1a", the fixed frame 1 includes: a lower frame 1-1 and an upper frame 1-2. The planar cam 1a is located in two places, respectively on the lower frame 1-1 and the upper frame 1-2. More specifically, the top of the lower frame 1-1 may have a plug-in section, and the bottom of the upper frame 1-2 may have a plug-in hole. Through the plug-in engagement of the plug-in section and the plug-in hole, the relative rotation between the upper frame 1-2 and the lower frame 1-1 is restricted, keeping the two planar cams 1a overlapping. The rotating frame 2 is equipped with two retaining rings 8, one above the other, which respectively block the two bearings 6, connecting the rotating frame 2 to the fixed frame 1 while restricting the separation of the upper frame 1-2 and the lower frame 1-1.

[0045] Please see Figure 2 In some embodiments, each separator 2a is rotatably equipped with guide wheels 2a1 corresponding to the two placement areas 7 it divides. In the working state, the outer wall of the yarn bobbin abuts against the corresponding two guide wheels 2a1, the movable limit wheel 5, and the fixed limit wheel 4, making the rotation of the yarn bobbin smoother and more convenient.

[0046] Furthermore, each partition strip 2a has a single guide wheel 2a1, the edge of which extends beyond the vertical outer walls on both sides of the partition strip 2a. Compared to having one guide wheel 2a1 on each side of the partition strip 2a, one guide wheel 2a1 can be used simultaneously for two placement areas 7, resulting in a simpler structure.
