[0049] As Figures 1 to 4As shown in the figure, the present utility model provides a vertical yarn rack 100. The vertical yarn rack 100 includes a support frame 110, a tray 120, and at least two fixing members 130. The tray 120 extends in the horizontal direction for supporting a bobbin 11 located thereon and a yarn 12 wound around the bobbin 11. The tray 120 is rotatably connected to the support frame 110. The fixing members 130 are movably connected to the tray 120 along the radial direction of the tray 120. At least two fixing members 130 are spaced apart along the circumferential direction of the tray 120. The fixing member 130 includes an axial section 131 and a radial section 132. The axial section 131 is located above the tray 120 to fix the bobbin 11; the radial section 132 is located below the tray 120, and the inner end of the radial section 132 is connected to the lower end of the axial section 131.

[0050] According to the vertical yarn rack of the present utility model, the structure is simple and the price is low. It can simply and conveniently load and unload the bobbin for winding yarn. The tray rotatably connected to the support frame supports the bobbin and drives the bobbin to rotate. The bobbin is firmly fixed to the tray during rotation and is not easily loosened or detached.

[0051] It should be noted that the tray 120 can be set completely horizontally or can be set approximately horizontally, such as being slightly inclined. In the illustrated embodiment, the tray 120 is set in the completely horizontal direction, and the axial direction of the tray 120 is parallel to the height direction of the support frame 110. The radial direction of the tray 120 is perpendicular to the height direction of the support frame 110. "Inner" and "outer" are based on the center of the tray 120. Towards the center of the tray 120 is inwards, and away from the center of the tray 120 is outwards.

[0052] Reference Figures 1 to 4 , the vertical yarn rack 100 can be used to unwind the yarn 12 wound around the bobbin 11 (or called a yarn bobbin), for example, unwind it to a downstream device. The vertical yarn rack 100 can include a support frame 110, a tray 120, at least two fixing members 130, a track member 135, a yarn guiding member 140, a main shaft 150, a bearing 160, a yarn dividing reed 170, a positioning shaft 180, and a universal wheel 190.

[0053] The yarn 12 can be a fiber material, such as glass fiber, carbon fiber, aramid fiber, etc., or can be other materials. The bobbin 11 and the yarn 12 wound around the bobbin 11 can also be called a yarn roll.

[0054] As Figure 1As shown, the support frame 110 may include end frames 111, side frames 112, and cross-frame bars 113. The two end frames 111 are disposed opposite to each other along the length direction. The side frames 112 are disposed between the two end frames 111. The two side frames 112 are disposed opposite to each other along the width direction. At least two cross-frame bars 113 are connected between the two side frames 112 along the width direction. Among them, the tray 120 is rotatably connected to the cross-frame bar 113. The tray 120 and the bobbin tube 11 are orderly placed on the cross-frame bar 113, saving space.

[0055] The side frame 112 may include at least two side-frame bars arranged at intervals along the height direction to provide more cross-frame bars 113, and thus install more trays 120, thereby improving the wire pay-off efficiency. In practical applications, two side-frame bars at the same height position and the cross-frame bar 113 connected between them may constitute one installation layer of the support frame 110. That is to say, the support frame 110 may include at least two installation layers to install at least two layers of trays 120, and thus support the bobbin tube 11 and the yarn 12 through the trays 120 and drive the bobbin tube 11 to rotate. The number and position of the yarn dividing reeds 170 and the positioning shafts 180 may correspond to the number and position of the installation layers.

[0056] Four universal wheels 190 may be provided at the bottom of the support frame 110, for example, respectively provided at the bottom of the end frames 111. The universal wheels 190 may be provided with braking components to control the movement of the vertical yarn rack 100. The support frame 110 may be a steel structure support frame 110.

[0057] In the illustrated embodiment, the two trays 120 may be arranged at intervals along the width direction. The positions of the two yarn guiding members 140, the two positioning shafts 180, and the two yarn dividing reeds 170 along the width direction correspond to the positions of the two trays 120 arranged along the width direction. Thus, wire pay-off can be performed simultaneously from both sides of the support frame 110 along the width direction to improve the wire pay-off efficiency.

[0058] The vertical yarn rack 100 may include at least two positioning shafts 180 and at least two yarn dividing reeds 170 along the height direction. The positions and numbers of the positioning shafts 180 and the yarn dividing reeds 170 may both correspond to the positions and numbers of the yarn guiding members 140 along the height direction.

[0059] In the illustrated embodiment, two trays 120 may be arranged along the width direction on each installation layer, and one yarn dividing reed 170 and one positioning shaft 180 may be respectively provided corresponding to both sides of each installation layer. The number of the yarn guiding members 140 may correspond one-to-one to the number of the trays 120.

[0060] In some embodiments, the yarn guide 140, the positioning shaft 180, and the yarn dividing reed 170 can all be disposed on the support frame 110, so that the vertical yarn rack 100 is integrally provided, facilitating the overall movement and use. For example, the positioning shaft 180 and the yarn dividing reed 170 can both be connected to the end frame 111, and the yarn guide 140 can be connected to the side frame 112.

[0061] The yarn guide 140 can be disposed downstream of its corresponding tray 120, that is to say, the yarn guide 140 can be disposed downstream of the bobbin 11 formed by its corresponding tray 120 and the yarn 12 wound around the bobbin 11, so as to convey the yarn 12 to devices such as the positioning shaft 180, the yarn dividing reed 170, etc. located downstream of the yarn guide 140. The yarn guide 140 can be provided with at least one yarn guide hole 141 along a direction parallel to the axial direction of the tray 120. For example, Figure 1 five yarn guide holes 141 in [reference], the positions of the yarn guide holes 141 are used to correspond to the positions of the bobbins 11. In other words, the positions of the yarn guide holes 141 correspond to the positions of the yarn 12 wound around the bobbins 11, so as to facilitate guiding the yarn 12. The number of the yarn guide holes 141 can be flexibly adjusted according to actual needs.

[0062] The main shaft 150 is rotatably connected to the support frame 110 via a bearing 160. The main shaft 150 can be coaxially arranged with the tray 120, and the tray 120 is fixedly connected to the main shaft 150. It can be understood that the main shaft 150 can be located inside the bobbin 11 supported on the tray 120 in the horizontal direction. The main shaft 150 can be driven to rotate by a device such as a motor, and then drive the tray 120 to rotate.

[0063] Reference Figure 2 、 Figure 3 and Figure 4 , the fixing member 130 is movably connected to the tray 120 along the radial direction of the tray 120. At least two fixing members 130 are spaced apart along the circumferential direction of the tray 120.

[0064] The fixing member may include an axial section 131 and a radial section 132. The tray 120 may be provided with at least two connection holes 121 such that the axial section 131 of the fixing member 130 axially passes through the connection holes 121 for extending into the interior of the bobbin 11. The positions and numbers of the connection holes 121 correspond to the positions and numbers of the fixing member 130. The radial section 132 of the fixing member 130 is located below the tray 120, and the radial section 132 may extend radially outward from the lower end of the axial section 131 to extend beyond the outer edge of the tray 120. The axial section 131 of the fixing member 130 is located above the tray 120 to fix the bobbin 11, for example, by a tight fit. The axial section 131 extends axially upward from the inner end of the radial section 132 to tightly fit with the inner wall of the bobbin 11. The dimension of the axial section 131 in the axial direction is not specifically limited. In actual operation, a relatively large dimension of the axial section 131 in the axial direction can more stably fix the bobbin 11.

[0065] The dimension of the connection hole 121 in the radial direction may be greater than the dimension of the axial section 131 in the radial direction, so that the axial section 131 can move in the radial direction in the connection hole 121, thereby adjusting the position of the axial section 131 in the radial direction, and thus facilitating the tight fit of the axial section 131 with the inner wall of the bobbin 11, and further fixing the bobbin 11.

[0066] In the illustrated embodiment, the fixing member 130 may be generally configured in an L shape. The connection between the axial section 131 and the radial section 132 may be configured as a bent fillet to facilitate processing and facilitate the fit with the hole wall of the connection hole 121.

[0067] In some embodiments, a fastener 133 may be provided at the outer end of the radial section 132 of the fixing member 130. The fastener 133 may protrude upward in the axial direction from the tray 120. The inner side of the fastener 133 in the radial direction can abut against the outer periphery of the tray 120, so that the axial section 131 of the fixing member 130 can tightly fit with the inner wall of the bobbin 11. A threaded portion may be provided at the outer end of the radial section 132 of the fixing member 130 for threaded fastening cooperation with a fastener 133 such as a nut. The dimension of the threaded portion in the radial direction may be greater than the thickness of the nut, so that the nut moves on the radial section 132 to adjust the position of the axial section 131 in the radial direction, thereby facilitating the tight fit of the axial section 131 with the inner wall of the bobbin 11, and further fixing the bobbin 11.

[0068] It can be understood that the dimension settings of the connection holes 121 and the threaded portion enable a certain variation space for the diameter of the bobbin 11, that is to say, it can be applicable to bobbins 11 with more diameters, expanding the application range.

[0069] Reference Figure 2 and Figure 4, in some embodiments, the tray 120 may be provided with at least two connection holes 121, and the at least two connection holes 121 may be evenly spaced in the circumferential direction. Thus, the at least two fixing members 130 may be evenly spaced in the axial direction, and the force exerted on the bobbin tube 11 by the fixing members 130 is relatively uniform, so that it is firmly fixed.

[0070] In the illustrated embodiment, the tray 120 is provided with 3 connection holes 121, and the 3 connection holes 121 are evenly spaced in the circumferential direction. Of course, if necessary and / or desired, the number and positions of the connection holes 121 and the fixing members 130 can be flexibly adjusted according to actual needs.

[0071] In some embodiments, the vertical yarn rack 100 may further include a rail member 135. The rail member 135 is connected to the lower side of the tray 120. The rail member 135 may include a guide rail groove 135a extending in the radial direction and a connecting plate 135b. The two connecting plates 135b are respectively connected to the two ends of the guide rail groove 135a in the axial direction. The connecting plate 135b is connected to the bottom surface of the tray 120. The radial section 132 is configured to be slidably movable at least partially in the guide rail groove 135a, so that the fixing member 130 can move conveniently and smoothly in the radial direction. The rail member 135 further supports the fixing member 130, which is beneficial to firmly fixing the bobbin tube 11 by the fixing member 130.

[0072] The positioning shaft 180 may be disposed downstream of the yarn guiding member 140 for collecting the yarns 12 passing through the yarn guiding holes 141 of the yarn guiding member 140. The positioning shaft 180 may be configured as an elongated column, and the axis of the positioning shaft 180 may be parallel to the width direction of the support frame 110.

[0073] The yarn dividing reed 170 may be disposed downstream of the yarn guiding member 140 for separating and guiding multiple strands of fiber filaments to downstream equipment. The yarn dividing reed 170 may be disposed downstream of the positioning shaft 180 to separate the yarns 12 collected by the positioning shaft 180. The yarn dividing reed 170 may include a connecting member 171 and multiple yarn dividing needles 172. The connecting member 171 may be connected to the support frame 110, and the multiple yarn dividing needles 172 are spacedly connected to the connecting member 171. Optionally, the multiple yarn dividing needles 172 may be evenly spaced to evenly separate and guide multiple strands of fiber filaments to downstream equipment.

[0074] According to the vertical yarn rack 100 of the present utility model, a tray 120, a yarn guide plate, a positioning shaft 180, and a yarn dividing reed 170 are sequentially arranged along the yarn unwinding direction. During operation, the bobbin 11 and the yarn 12 wound around the bobbin 11 are placed on the tray 120, and the respective axial segments 131 of at least two fixing members 130 are located inside the bobbin 11 along the horizontal direction. At the same time, the radial segments 132 of the fixing members 130 are pulled outward in the radial direction until the axial segments 131 of the fixing members 130 are substantially in contact with the inner wall of the bobbin 11. Then, a fastening member 133 such as a nut is tightened until the fastening member 133 abuts against the outer edge of the tray 120. The yarn 12 is led out through the yarn guide hole 141 of the yarn guide plate located downstream of the outside of the yarn end. Preferably, the yarn 12 is led out through the yarn guide hole 141 at a substantially equal height. A power device such as a motor is started to rotate the main shaft 150. The main shaft 150 drives the tray 120 to rotate via the bearing 160 to unwind the yarn evenly. Multiple yarns 12 from multiple trays 120 are gathered at the positioning shaft 180 downstream of the yarn guide hole 141. If the yarn inlet height of a downstream device such as the yarn dividing reed 170 is higher than the height of the positioning shaft 180, the yarn 12 bypasses the positioning shaft 180 from below; if the yarn inlet height of a downstream device such as the yarn dividing reed 170 is lower than the height of the positioning shaft 180, the yarn 12 bypasses the positioning shaft 180 from above. Thus, the yarn 12 is not easily detached and is continuously and stably conveyed. The yarn 12 output from the positioning shaft 180 can pass through the yarn dividing reed 170. Multiple yarn dividing needles 172 of the yarn dividing reed 170 comb and separate the yarn 12 and then continue to convey it to other downstream devices.
