Description

Technical Field

[0001] The present invention relates to the technical field of bobbin detection, and particularly relates to a winding bobbin tube type detection device and method. Background Art

[0002] Winding is a process of winding the cheese or hank yarn from the spinning section onto a bobbin with a larger capacity, good shape, and suitable for subsequent processing through a winding machine. It is an important process in textile production. The purpose is to increase the winding capacity, improve the yarn quality, and form a suitable winding form. First, the cheese or hank yarn is installed on the unwinding device of the winding machine, and the yarn is unwound from the original yarn package. Then, the yarn tension is adjusted through a tension device to keep the yarn at an appropriate tension during the winding process, ensuring that the bobbin is wound tightly and has a good shape. Next, a yarn clearer is used to remove impurities and defects on the yarn. Finally, the yarn after tension control and yarn clearing is wound onto the bobbin under the action of the winding mechanism of the winding machine to form a bobbin yarn.

[0003] In the prior art, before the bobbin is sent to an automatic winding machine for winding, usually only the appearance of the bobbin is observed by the staff with the naked eye, which is very likely to result in missed or misjudged inspections. Non-compliant bobbins will continue to enter the automatic winding process, leading to multiple yarn breaks, neps, and poor-shaped yarns mixing into the process, reducing the product quality. Summary of the Invention

[0004] The present invention discloses a winding bobbin tube type detection device and method, aiming to solve the technical problem that in the background art, only the staff observes the bobbin with the naked eye before winding, which is very likely to result in missed or misjudged inspections, leading to multiple yarn breaks, neps, and poor-shaped yarns mixing into the process.

[0005] A winding bobbin tube type detection device proposed by the present invention includes a main frame. A plurality of fixing rods are fixedly connected to the inner wall of the main frame. The outer part of the plurality of fixing rods is slidably connected with the same mounting frame. A visual detection module and a cleaning module are arranged on the mounting frame. And a fixed ejection module is arranged on the inner wall of the top of the main frame. The visual detection module includes a first toothed ring, the first toothed ring is movably connected to the inner wall of the mounting frame, and a mounting member is fixedly connected to the inner wall of one side of the first toothed ring. A detection device body is fixedly connected to the mounting member. The cleaning module includes a movable frame, and an air pump is fixedly connected to the inner wall of the movable frame. The output end of the air pump is fixedly connected to a filter chamber. The fixed ejection module includes a sliding block, and an installation groove is opened at the bottom of the sliding block. A hydraulic rod is fixedly connected to the installation groove, and the driving end of the hydraulic rod is fixedly connected to a fixed table.

[0006] In a preferred solution, a driving motor is fixedly connected to one side of the mounting frame. The output end of the driving motor is fixedly connected to a first gear, and the first gear meshes with the first toothed ring.

[0007] In a preferred embodiment, two symmetrically arranged double-headed motors are fixedly connected to the top of the main frame, and winding wheels are fixedly connected to the two output ends of the two double-headed motors. Winding ropes are wound around the outside of the plurality of winding wheels, and one end of each of the plurality of winding ropes away from the winding wheels is fixedly connected to the top of the mounting frame.

[0008] By providing a visual detection module, the double-headed motor rotates the winding wheel to loosen the winding rope, and the mounting frame descends to a specified height. The drive motor rotates the first gear, which meshes with and rotates the first toothed ring, driving the circumferential movement of the detection device body to perform visual recognition and detection on the shape of the yarn tube, avoiding missed detection and misdetection, preventing yarn with multiple breakages, neps, and poor forming from mixing into the process, and improving product quality.

[0009] In a preferred embodiment, a mounting bracket is fixedly connected to the top of the mounting frame. A circular hole is formed in the mounting bracket, and a movable bracket is movably connected in the circular hole. A universal motor is fixedly connected to the mounting frame, and the output end of the universal motor is fixedly connected to one side of the movable bracket.

[0010] In a preferred embodiment, a sliding frame is movably connected to the inner wall of the filter chamber. A filter screen is fixedly connected to the inner wall of the sliding frame, and a spring is fixedly connected to one side of the sliding frame. The end of the spring away from the sliding frame is fixedly connected to the inner wall of the filter chamber.

[0011] In a preferred embodiment, a mounting hole is formed in the filter chamber. An arc-shaped pipe is fixedly connected in the mounting hole. A plurality of air holes are circumferentially and equidistantly formed in the arc-shaped pipe, and one end of the arc-shaped pipe away from the filter chamber is fixedly connected to the outer wall of the movable bracket.

[0012] By providing a cleaning module, when impurities such as yarn fluffs adhere to the outside of the detection device body, the universal motor reciprocally rotates the movable bracket. At the same time, the air pump filters air through the filter screen and then passes it into the arc-shaped pipe, where it is ejected from the air holes to blow off the impurities adhering to the outside of the detection device body, preventing occlusion from affecting detection. And through the elastic action of the spring, the sliding frame continuously reciprocally vibrates under the action of the wind force, avoiding blockage of the filter screen.

[0013] In a preferred embodiment, a fixed frame is fixedly connected to the inner wall of the top of the main frame. A rotating hole is formed in the fixed frame. A threaded rod is movably connected in the rotating hole. A sliding block is threadedly connected to the outside of the threaded rod. A servo motor is fixedly connected to one side of the fixed frame, and the output end of the servo motor is fixedly connected to one end of the threaded rod.

[0014] In a preferred embodiment, an annular groove is formed in the fixed table. An activity ring is movably connected in the annular groove. A second toothed ring is fixedly connected to the outer wall of the activity ring. One side of the fixed table is fixedly connected with a stepper motor. The output end of the stepper motor is fixedly connected with a second gear. The second gear meshes with the second toothed ring. A plurality of arc-shaped grooves are equidistantly arranged in a circumferential manner on the activity ring. A plurality of sliding rods are slidably connected in the plurality of arc-shaped grooves. The bottoms of the plurality of sliding rods are all fixedly connected with activity rods.

The plurality of support rods are equidistantly arranged in a circumferential manner. One ends of the plurality of support rods away from the sliding member are all movably connected to the corresponding fixing kits.

[0016] By providing a fixed ejection module, when the yarn bobbin is conveyed into the interior of the main frame, the hydraulic rod supporting member descends into the yarn bobbin. The stepper motor is started to rotate the second gear. The activity ring is rotated through the meshing of the second toothed ring, forcing the sliding rod to slide in the arc-shaped groove, driving the activity rod to expand outwards until the supporting member closely adheres to the inner wall of the yarn bobbin, so as to stably clamp the yarn bobbin without blocking the yarn bobbin. The hydraulic rod contracts to lift the height of the yarn bobbin for convenient detection. If the detection is unqualified, the servo motor is started to rotate the threaded rod to drive the sliding block to send the yarn bobbin out of the conveying line to prevent it from continuing to enter the winding process.

[0017] Meanwhile, the present invention also proposes a method for detecting the tube shape of a winding yarn bobbin, using the above-mentioned winding yarn bobbin tube shape detection device, including the following steps:

[0018] Step 1: When the yarn bobbin is conveyed into the interior of the main frame, the hydraulic rod pushes the supporting member to descend into the yarn bobbin. The stepper motor rotates the second gear, meshing and rotating the activity ring, forcing the sliding rod to slide in the arc-shaped groove, driving the activity rod to expand outwards, making the supporting member closely adhere to the inner wall of the yarn bobbin. Then the hydraulic rod lifts the height of the yarn bobbin for convenient detection;

[0019] Step 2: The double-headed motor rotates the winding wheel to loosen the winding rope. The installation frame descends to a specified height. The driving motor rotates the first gear, meshing and rotating the first toothed ring, driving the detection device body to perform a circumferential movement to visually identify and detect the tube shape of the yarn bobbin. If the detection is unqualified, the servo motor is started to rotate the threaded rod to drive the sliding block to send the yarn bobbin out of the conveying line;

[0020] Step 3: When impurities such as yarn fluffs adhere to the outside of the detection device body, the universal motor rotates the movable frame reciprocally. The air pump filters the air through the filter screen in the filter bin and then passes it into the arc-shaped tube, where it is ejected from the air holes to blow off the impurities adhering to the outside of the detection device body. Meanwhile, due to the elastic action of the spring, the sliding frame vibrates reciprocally continuously to prevent blockage.

[0021] Beneficial effects:

[0022] The bobbin tube shape detection device provided by the present invention can, before the bobbin undergoes winding, identify and detect the bobbin tube shape through the visual detection module, avoid missed detection and misdetection, prevent yarn with multiple breakages, neps, and poor forming from mixing into the process, improve product quality. At the same time, after long-term operation, the cleaning module can clean impurities such as yarn fluffs adhering to the outside of the detection device to prevent occlusion from affecting detection. And through the fixed ejection module, the bobbin can be stably clamped without obstructing the bobbin, and when the detection is unqualified, the bobbin can be conveniently sent out of the conveyor line.

[0043] In a specific application scenario, when impurities such as yarn flocs adhere to the outside of the detection device body 704, the universal motor 803 reciprocally rotates the movable frame 802, and at the same time, the air pump 804 filters the air through the filter screen 810 and then introduces it into the arc-shaped pipe 805, and sprays it out from the air holes 806 to blow off the sundries adhering to the outside of the detection device body 704, preventing occlusion and affecting detection. And through the elastic action of the spring 809, the sliding frame 808 continuously reciprocally vibrates under the action of wind force, avoiding blockage of the filter screen 810.

[0044] Refer to Figure 1 、 Figure 6 and Figure 7 , a fixed frame 901 is fixedly connected to the inner wall of the top of the main frame 1. A rotating hole is provided on the fixed frame 901.

[0047] In a specific application scenario, when the yarn bobbin is transported into the interior of the main frame 1, the hydraulic rod 905 and the fixture 915 descend into the interior of the yarn bobbin. The stepper motor 909 is started to rotate the second gear 910, and the second toothed ring 908 is engaged to rotate the movable ring 907, forcing the sliding rod 912 to slide within the arc-shaped groove 911, driving the movable rod 913 to expand outwards until the fixture 915 closely adheres to the inner wall of the yarn bobbin, enabling stable clamping of the yarn bobbin without obstructing it. The hydraulic rod 905 contracts to lift the height of the yarn bobbin to facilitate inspection. If the inspection is unqualified, the servo motor 902 is started to rotate the threaded rod 903, driving the sliding block 904 to send the yarn bobbin out of the conveyor line to prevent it from continuing to enter the winding process.

[0048] The second aspect of the present invention provides a method for detecting the tube shape of a winding yarn bobbin, including the following steps:

[0049] Step 1: When the yarn bobbin is transported into the interior of the main frame 1, the hydraulic rod 905 pushes the fixture 915 to descend into the interior of the yarn bobbin. The stepper motor 909 rotates the second gear 910, meshing and rotating the movable ring 907, forcing the sliding rod 912 to slide within the arc-shaped groove 911, driving the movable rod 913 to expand outwards, making the fixture 915 closely adhere to the inner wall of the yarn bobbin. Then, the hydraulic rod 905 lifts the height of the yarn bobbin to facilitate inspection.

[0050] Step 2: The double-headed motor 4 rotates the winding wheel 5 to relax the winding rope 6. The mounting frame 2 descends to a specified height. The driving motor 702 rotates the first gear 703, meshing and rotating the first toothed ring 701, driving the detection device body 704 to perform a circular motion to visually identify and detect the tube shape of the yarn bobbin. If the inspection is unqualified, the servo motor 902 is started to rotate the threaded rod 903, driving the sliding block 904 to send the yarn bobbin out of the conveyor line.

[0051] Step 3: When impurities such as yarn fluffs adhere to the exterior of the detection device body 704, the universal motor 803 reciprocally rotates the movable frame 802. The air pump 804 filters the air through the filter screen 810 in the filter chamber 807 and then passes it into the arc-shaped tube 805, spraying out from the air holes 806 to blow off the impurities adhering to the exterior of the detection device body 704. And through the elastic action of the spring 809, the sliding frame 808 continuously vibrates reciprocally to prevent blockage.

[0052] When the yarn bobbin is conveyed into the interior of the main frame 1, the double-headed motor 4 is started to rotate the winding wheel 5, so that the winding rope 6 is relaxed, and the mounting frame 2 descends to a specified height under the action of gravity. At the same time, the hydraulic rod 905 is started to push the fixed table 906, so that the supporting member 915 descends into the interior of the yarn bobbin. The stepping motor 909 is started to rotate the second gear 910, and the movable ring 907 is rotated through the engagement of the second toothed ring 908, forcing the sliding rod 912 to slide in the arc-shaped groove 911, driving the movable rod 913 to expand outwards until the supporting member 915 closely adheres to the inner wall of the yarn bobbin. The hydraulic rod 905 contracts to lift the height of the yarn bobbin to facilitate the detection. At this time, the driving motor 702 is started to rotate the first gear 703, which meshes and rotates the first toothed ring 701, driving the detection device body 704 to perform a circular motion to visually identify and detect the tube shape of the yarn bobbin. If the detection is unqualified, the servo motor 902 is started to rotate the threaded rod 903 to drive the sliding block 904, and the yarn bobbin is sent out of the conveying line to prevent it from continuing to enter the winding process. When the device works for a long time and a large amount of impurities such as yarn fluffs adhere to the outside of the detection device body 704, the general motor 803 is started to reciprocally rotate the movable frame 802, driving the arc-shaped tube 805 to reciprocally rotate. At the same time, the air pump 804 is started, and the air is filtered through the filter screen 810 in the filter bin 807 and then introduced into the arc-shaped tube 805 and sprayed out from the air holes 806 to blow off the impurities adhering to the outside of the detection device body 704. And through the elastic action of the spring 809, the sliding frame 808 continuously reciprocally vibrates under the action of the wind force to prevent the filter screen 810 from being blocked.

10. A method for detecting the tube shape of a winding yarn tube, using the device for detecting the tube shape of a winding yarn tube as claimed in claim 9, characterized in that: The steps include: Step 1: When the bobbin is transported to the inside of the main frame (1), the hydraulic rod (905) pushes the supporting fixture (915) down to the inside of the bobbin, and the stepping motor (909) rotates the second gear (910), meshing and rotating the movable ring (907), forcing the sliding rod (912) to slide in the arc groove (911), driving the movable rod (913) to expand outward, so that the supporting fixture (915) is closely attached to the inner wall of the bobbin, and then the hydraulic rod (905) raises the height of the bobbin to facilitate detection; Step 2: The double-headed motor (4) rotates the winding wheel (5) to loosen the winding rope (6), and the mounting frame (2) is lowered to a specified height. The driving motor (702) rotates the gear 1 (703), which engages with the rotating gear ring 1 (701), and drives the detection device body (704) to move in a circular motion, and visually identifies and detects the tube type of the yarn tube. If the detection is unqualified, the servo motor (902) is started to rotate the threaded rod (903), and the sliding block (904) is driven to send the yarn tube out of the conveyor line; Step 3. When impurities such as yarn flocs are attached to the outside of the detection device body (704), the universal motor (803) reciprocates the movable frame (802), and the air pump (804) filters the air through the filter screen (810) in the filter bin (807) and passes it into the arc tube (805), and sprays it out from the air hole (806) to blow off the debris attached to the outside of the detection device body (704), and the elastic action of the spring (809) causes the sliding frame (808) to vibrate back and forth continuously to prevent blockage.
