Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, and in particular relates to an automatic feeding and recycling component for a cylindrical layer. Background Art

[0002] Pre-oriented yarn (POY) produced by melt spinning is generally not used directly for weaving and must undergo post-processing before use. Texturing involves stretching and deforming POY yarn, transforming it into a draw-textured yarn (DTY) with relatively stable physical properties suitable for direct weaving. The POY yarn is placed on a bobbin and conveyed to a texturing machine, where it undergoes tensile forces, false twisting forces, and heat, causing stretching, deformation, and heat setting, resulting in a draw-textured yarn with a defined strength, elongation, and bulk.

[0003] POY yarn raw material is wound onto bobbins, which are then placed on the bobbin rollers of the POY yarn rack. The POY yarn on the bobbins is continuously fed to the texturing machine. However, the bobbin rollers on the current POY yarn racks are fixed in place. Once all the POY yarn on the bobbins on the rollers has been used up, the equipment must be paused to remove the empty bobbins and then place new bobbins on the rollers. Only after these operations are completed can POY yarn processing continue. This pauses the processing, resulting in reduced efficiency. Utility Model Content

[0004] The utility model provides an automatic bobbin feeding and recycling assembly. The assembly is equipped with several bobbin rollers, each of which is equipped with a bobbin of POY yarn. The bobbin rollers are located on a rotatable turntable. By rotating the bobbin rollers, after the POY raw material on the current bobbin roller is delivered, the next bobbin roller can immediately take its place under the rotation of the turntable, so that the raw material is automatically fed and production is not suspended. At the same time, the empty bobbin on the unloaded bobbin roller can be removed and replaced with a full bobbin. This avoids the problem of existing POY yarn racks pausing production and processing to recover empty bobbins and replenish new bobbins, which leads to reduced processing efficiency.

DETAILED DESCRIPTION

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] Example 1

[0049] A bobbin layer automatic feeding and recycling assembly, comprising: a first base 1, a second base 2, a rotating disk 3, a fixed disk 5, and a bobbin roller 4;

[0050] The first base 1 and the second base 2 are bases that support the left and right sides of the entire POY yarn rack; they can also be part of the left and right support bases of the entire POY yarn rack; that is, multiple sets of the barrel layer automatic feeding and recovery components in this embodiment can be set on one POY yarn rack.

[0051] like Figure 1 As shown, a turntable is provided on the right side of the first base 1, and the turntable can rotate relative to the first base 1; the specific structure between the turntable 3 and the first base 1 is as shown in FIG. Figure 3 As shown, a shaft core rod 301 is disposed at the center of the turntable 3. One end of the shaft core rod 301 extends from the left side of the turntable 3 through the turntable 3 to the right side of the turntable 3. The other end of the shaft core rod 301 passes through the first base 1 and is connected to the rotor of the turntable motor. The shaft core rod 301 is rotatable relative to the first base 1. The rotation of the turntable motor rotor drives the shaft core rod 301 to rotate, and the shaft core rod 301 then drives the turntable 3 to rotate.

[0052] like Figure 1As shown, a second base 2 is provided on one side of the first base 1, and a fixed disk 5 is provided on the second base 2 via a hydraulic column 6; the hydraulic column 6 is provided transversely through the second base 2, and the telescopic end of the hydraulic column 6 is completely located outside the second base 2 and faces the first base 1; the base portion of the hydraulic column 6 is located inside the second base 2, and the tail end of the base portion of the hydraulic column 6 extends out of the second base 2; the end position of the telescopic end located outside the second base 2 is connected to the center of the fixed disk 5; in this way, when the hydraulic column 6 is extended or retracted, it can drive the fixed disk 5 to move toward or away from the turntable 3. The hydraulic column 6 is communicatively connected to the hydraulic column control assembly, which is an existing product, and its control assembly and control circuit are existing technologies, and the details are not repeated here; those skilled in the art are capable of selecting and implementing the hydraulic column 6.

[0053] As a preferred embodiment, the hydraulic column 6 itself passes through the second base 2 horizontally, and a part of the tail end extends out of the second base 2; in order to maintain the balance and stability of the hydraulic column 6, a diagonal support rod 601 is arranged between the tail end of the hydraulic column 6 and the second base 2; the head end of the diagonal support rod 601 is connected to the tail end of the hydraulic column 6, and the tail end of the diagonal support rod 601 is connected to the surface of the second base 2; in this way, the auxiliary supporting function of the diagonal support rod 601 can maintain the balance and stability of the installation of the hydraulic column 6.

[0054] The existing POY yarn rack is provided with a bobbin roller 4, and the raw yarn bobbin of the POY yarn is placed on the bobbin roller 4 to facilitate the output of the yarn; Figure 1 As shown, in this embodiment, multiple sets of spool rollers 4 are provided, and the first ends of the spool rollers 4 are rotatably provided on the right side of the turntable 3 through the rotating shaft, and the spool rollers 4 are distributed on the right side of the turntable 3 at equal intervals; and the second ends of the spool rollers 4 are detachably provided on the left side of the fixed disk 5, and the second ends of the spool rollers 4 are rotatably provided between the left side of the fixed disk 5; the connection structure between the second ends of the spool rollers 4 and the fixed disk 5 is as shown in FIG. Figure 6 As shown, on the left side of the fixed disk 5 , a rotating shaft sleeve 501 is provided corresponding to the second end of each bobbin roller 4 , the second end of the bobbin roller 4 is inserted into the rotating shaft sleeve 501 , and the bobbin roller 4 can rotate relative to the rotating shaft sleeve 501 .

[0055] Before production begins, hydraulic column 6 is retracted, moving fixed disk 5 away from turntable 3. The second end of spool roller 4 disengages from rotating sleeve 501 and maintains a certain distance from fixed disk 5. From this distance, a fully wound bobbin of yarn is added to spool roller 4. The inner wall of the bobbin should fit snugly against the outer wall of spool roller 4, creating an interference fit. Once the bobbin is fully replenished, hydraulic column 6 is extended, allowing the second end of spool roller 4 to enter rotating sleeve 501. The bobbin on spool roller 4 in the delivery position can then begin delivering POY yarn. Spool roller 4 can hold multiple bobbins from its first end to its second end. Delivery begins with the first bobbin at the first end and continues until the last bobbin at the second end. When all the raw silk bobbins on the spool roller 4 at the conveying position are output, the fixed disk 5 is controlled to separate from the spool roller 4, and then the turntable motor is controlled to rotate the turntable motor at a fixed angle, and the next spool roller 4 is immediately replaced to the output position to continue outputting the silk thread, and the previous empty raw silk bobbin is rotated to the recovery position, and the staff removes the empty raw silk bobbin and replaces it with a fully wound raw silk bobbin; then the fixed disk 5 is restored to its original position; in this way, there will be no silk thread output at the output position due to replenishment of raw materials, and it can be ensured that there is always raw silk thread output at the output position, so that production is continuous and production efficiency is greatly improved.

[0056] The above-mentioned turntable motor adopts a servo motor or is controlled by a travel switch; its rotation angle can be accurately controlled; the angle of one rotation of the turntable 3 is set according to the number of bobbin rollers 4 on the turntable 3; for example, in this embodiment, four bobbin rollers 4 are set on the turntable 3, then the angle of one rotation of the bobbin rollers 4 is set to 90°; the servo motor or travel switch is an existing product, and its control circuit belongs to the existing technology, which will not be repeated here.

[0057] Example 2

[0058] Based on the first embodiment, in the first embodiment, both the turntable motor and the hydraulic cylinder 6 require manual control. Specifically, a human operator is required to check whether the POY yarn on the bobbins on the bobbins roller 4 at the delivery position has been fully delivered. Once fully delivered, the fixed plate is controlled to disengage from the bobbins roller 4 and the turntable 3 to rotate, replenishing the material at the delivery position. This does not achieve automatic material replenishment and may lead to negligence, resulting in the delivery position being empty of material for a long time.

[0059] like Figure 2 As shown, in this embodiment, a patch pressure sensor 401 is provided near the second end of each bobbin roller 4 and on the outer wall of the bobbin roller 4; the patch pressure sensors 401 are distributed in a circular pattern, so as to ensure that every position on the bobbin roller 4 can be monitored to avoid monitoring omissions.

[0060] The patch pressure sensor 401 is set at the position where the last raw silk drum is placed near the second end of the spool roller 4; the patch pressure sensor 401 is connected to the PLC for communication; the PLC is connected to the hydraulic column control component and the turntable motor for communication.

[0061] Because the yarn is fed from the first bobbin at the first end of the bobbin roller 4 to the last bobbin at the second end; when the yarn on the last bobbin is fully fed, the pressure signal monitored by the patch pressure sensor 401, processed by the PLC, should equal the weight of the empty bobbin. At this point, the PLC controls the hydraulic telescopic column 6 to move the fixed disk 5, causing the second end of the bobbin roller 4 to leave the rotating shaft sleeve 501. It then controls the rotation of the turntable 3, causing the next bobbin roller 4 to rotate to the feeding position to continue feeding the POY yarn. The previous bobbin roller 4 rotates to the recovery position, removes the empty bobbin, and replaces it with a full bobbin. Then, the fixed disk 5 is restored to its original position. In this way, when the yarn raw material at the feeding position is fully fed, the material can be automatically replenished, avoiding the long-term lack of raw material due to the feeding position not being replenished in time.

[0062] Example 3

[0063] Based on Example 1, in Example 1, the second end of the spool roller 4 enters the rotating shaft sleeve 501, so that after the fixed disk 5 contacts the spool roller 4, the spool roller 4 can rotate relative to the fixed disk 5.

[0064] In order to make the second end of the spool roller 4 rotate more smoothly in the rotating shaft sleeve 501; Figure 7 As shown, in this embodiment, a movable ball 5012 is embedded on the inner wall of the rotating shaft sleeve 501, and the ball 5012 contacts the outer wall of the second end of the bobbin roller 4. Under the action of the ball 5012, the friction between the bobbin roller 4 and the rotating shaft sleeve 501 can be reduced.

[0065] like Figure 8 As shown, the structural relationship between the ball 5012 and the shaft sleeve 501 is set as follows: a number of ball movable grooves 5011 are opened at equal intervals in a circle on the inner side wall of the shaft sleeve 501; the notch of the ball movable groove 5011 is opened on the inner wall of the shaft sleeve 501; a ball 5012 is movably set in the ball movable groove 5011, and the notch of the ball movable groove 5011 is in a retracted state; the ball 5012 is just stuck at the notch of the ball movable groove 5011 and cannot be separated from the ball movable groove 5011; the inner bottom surface of the ball movable groove 5011 is connected to one end of the elastic member 5013, and the other end of the elastic member 5013 is connected to the spherical cover plate 5014; the spherical cover plate 5014 is attached to the surface of the ball 5012, but has no connection with the ball 5012. Figure 9 As shown, the structure of the spherical cover plate 5014 is equivalent to a curved spherical concave plate, and the inner concave surface can be attached to the surface of the ball 5012;

[0066] When the second end of the spool roller 4 is inserted into the rotating shaft sleeve 501, the outer wall of the spool roller 4 will squeeze the ball 5012, and the ball 5012 may retract into a part of the ball movable groove 5011. However, under the action of the elastic member 5013, the ball 5012 will still contact the outer wall of the spool roller 4, thereby reducing the rotational friction of the spool roller 4; when the second end of the spool roller 4 is separated from the rotating shaft sleeve 501, the ball 5012 will return to its original position under the action of the elastic member 5013.

[0067] Example 4

[0068] Based on Example 1, in Example 1, the bobbin roller 4 is rotatably arranged on the right side of the turntable 3; the bobbin roller 4 can only rotate passively; that is, after the raw silk bobbin is placed on the bobbin roller 4, the raw silk bobbin is driven to rotate when the silk thread is transported, and the raw silk bobbin will drive the bobbin roller 4 to rotate passively; in this way, although the silk thread is tensioned, the force it needs to withstand is relatively large, which may cause the silk thread to break.

[0069] like Figure 4 As shown, in this embodiment, several motors 402 are installed on the left side of the turntable 3; one motor 402 is installed for each bobbin roller 4. The rotor of motor 402 passes through the turntable 3 and is connected to the center of the first end surface of bobbin roller 4. The rotation of motor 402 can drive the bobbin roller 4 to rotate actively. This can maintain a certain tension in the silk thread. During the silk thread conveying process, the bobbin roller 4 can maintain active rotation synchronously with the original silk bobbin, reducing the tension on the silk thread.
