Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and in particular to a brush head finding device and a yarn feeding robot with multiple head finding zones. Background Technology

[0002] In the automated process of thread end extraction, a brush is typically used to contact the surface of the yarn bobbin, causing the bobbin to rotate so that the brush moves relative to the yarn surface, thus enabling the brush to locate the thread end. However, when multiple yarn bobbins need to be located simultaneously, multiple brushes are required, which not only increases costs but also reduces cleaning efficiency because the brushes need to be cleaned periodically. Utility Model Content

[0003] Therefore, it is necessary to address the problem that when multiple yarn bobbins need to be located simultaneously, multiple brushes are required, which increases costs and reduces cleaning efficiency. To address this issue, a brush-based yarn finding device with multiple finding zones and a yarn feeding robot that can reduce costs and improve cleaning efficiency should be provided.

[0004] This application provides a brush head finding device with multiple head finding areas for finding the thread ends of yarn located at the head finding station. The brush head finding device includes:

[0005] The brush has a first axis of rotation, and the brush is divided into multiple head-finding areas along the direction of the first axis of rotation.

[0006] A rotating mechanism, which can be connected to the first rotating shaft of the brush, is used to provide the driving force for rotating the brush; and

[0007] A moving mechanism, which can be connected to a rotating mechanism, is used to provide the driving force to move the rotating mechanism;

[0008] The rotating mechanism includes a contact position and a separation position during its movement. When the rotating mechanism is in the contact position, each head-finding area of ​​the brush is in contact with a corresponding yarn tube located at the head-finding station. When the rotating mechanism is in the separation position, the brush separates from the yarn tube.

[0009] The aforementioned brush-based yarn finding device with multiple yarn finding zones allows the yarn on the surface of the bobbin to easily adhere to the brush. Furthermore, because the yarn ends can coil and wrap around the brush, they are less likely to fall off, thus improving the overall success rate of yarn finding. In addition, the brush has multiple yarn finding zones along the first axis of rotation, each zone corresponding to one bobbin. Therefore, the same brush can simultaneously find the yarn ends of multiple bobbins, improving the efficiency of the brush-based yarn finding process, reducing the cost of setting up multiple brushes, and since only one brush is used, only one brush needs to be cleaned periodically, thus improving cleaning efficiency.

[0010] In one embodiment, the first rotating shaft is perpendicular to the axis of the bobbin located at the head-finding station.

[0011] In one embodiment, the brush head finding device further includes an air blowing mechanism;

[0012] The air blowing mechanism is located on one side of the brush in a direction perpendicular to the first rotating shaft. The air blowing mechanism is used to blow air onto the bobbin located at the head-finding station in the direction of the brush.

[0013] In one embodiment, the blowing mechanism includes a plurality of blowing sections;

[0014] The number of air blowing sections is the same as the number of head finding areas, and each air blowing section is located on one side of the head finding area corresponding to the brush in a direction perpendicular to the first rotating axis. Each air blowing section is used to blow air onto the bobbin located at the head finding station in the direction of the brush.

[0015] In one embodiment, the blowing part is configured as a spherical nozzle.

[0016] In one embodiment, the brush head finding device further includes an air blowing adjustment mechanism, which is movably connected to the air blowing mechanism and is used to adjust the distance between the air blowing mechanism and the brush in a direction perpendicular to the first rotating axis.

[0017] In one embodiment, the rotating mechanism is connected to one end of the first rotating shaft of the brush, and the other end of the first rotating shaft is suspended.

[0018] In one embodiment, the rotating mechanism includes a rotating drive and a pulley transmission mechanism, wherein the rotating drive is connected to the first rotating shaft of the brush via the pulley transmission mechanism.

[0019] In one embodiment, the brush head finding device further includes a mounting base, and the moving mechanism includes a moving drive and a moving guide rail. The brush and the rotating mechanism are both mounted on the mounting base, and the mounting base and the moving guide rail are slidably engaged. The moving drive is connected to the mounting base and is used to provide a driving force to move the mounting base.

[0020] Another aspect of this application provides a yarn-feeding robot, including the brush head-finding device in any of the above embodiments.

[0021] The aforementioned yarn feeding robot, by incorporating a brush, allows yarn on the surface of the yarn tube to easily adhere to the brush. Furthermore, because the yarn ends can coil and wrap around the brush, they are less likely to fall off, thus improving the overall success rate of yarn finding. In addition, the brush has multiple yarn finding zones along the first axis of rotation, each zone corresponding to one yarn tube. Therefore, the same brush can simultaneously find yarn ends from multiple yarn tubes, improving the efficiency of yarn finding, reducing the cost of setting up multiple brushes, and since there is only one brush, only one brush needs to be cleaned periodically, thus improving cleaning efficiency.

[0034] Figure 1 This is a three-dimensional structural diagram of a brush head finding device with multiple head finding areas according to an embodiment of this application; Figure 2 for Figure 1 The figure shows a front view of a brush head finding device with multiple head finding zones. For ease of description, the figures only show the structure relevant to the embodiments of this application.

[0035] Referring to the accompanying drawings, one embodiment of this application provides a brush head finding device 100 with multiple head finding areas, used to find the yarn ends of a bobbin located at the head finding station. The brush head finding device 100 includes a brush 10, a rotating mechanism 20, and a moving mechanism 30. The brush head finding device 100 of this application can be applied to yarn feeding robots, or to other equipment that uses the brush head finding device 100.

[0036] A brush 10 refers to a structure having bristles made of materials such as hair, metal wire, or synthetic fibers. In embodiments of this application, the brush 10 is a rotating body with a first axis of rotation. The brush 10 may have bristles all around its circumference, or bristles may be present in only a portion of its area. In embodiments of this application, the brush 10 is divided into multiple head-finding areas AA along the direction of the first axis of rotation. The head-finding area AA is an area capable of correspondingly locating the end of the yarn tube. The direction of the first axis of rotation may be parallel to the horizontal direction. Each head-finding area AA should be a circumferential area surrounding the first axis of rotation. The head-finding areas AA may be adjacent to each other or spaced apart. In embodiments of this application, the brush 10 as a whole has bristles all along its first axis of rotation, and the head-finding areas AA are adjacent to each other. Specifically, the head-finding area AA includes at least two, or optionally, three, and each head-finding area AA has the same size along the direction of the first axis of rotation to find the thread ends of the same type of yarn tube. Of course, the sizes of each head-finding area AA along the direction of the first axis of rotation can also be different to find the thread ends of different types of yarn tube.

[0037] The rotating mechanism 20 can be connected to the first rotating shaft of the brush 10 to provide the driving force for the brush 10 to rotate.

[0038] The moving mechanism 30 can be connected to the rotating mechanism 20 to provide a driving force for moving the rotating mechanism 20. That is, driven by the moving mechanism 30, the rotating mechanism 20 moves, and the brush 10 on the rotating mechanism 20 also moves together, thereby causing relative movement between the brush 10 and the yarn tube. Specifically, the moving mechanism 30 can provide a driving force for the rotating mechanism 20 to move in a direction perpendicular to the first axis of rotation of the brush 10, thereby causing the brush 10 and the yarn tube to move closer or further apart.

[0039] The rotating mechanism 20 includes a contact position and a separation position during its movement. When the rotating mechanism 20 is in the contact position, each head-finding area AA of the brush 10 is in contact with a corresponding bobbin located at the head-finding station. When the brush 10 or the bobbin is in the separation position, the brush 10 separates from the bobbin.

[0040] In practical applications, the moving mechanism 30 drives the rotating mechanism 20 to move the brush 10 closer to the yarn tube to the contact position, so that the brush 10 is in contact with the yarn tube and drives the brush 10 to rotate. In this way, the thread ends on the surface of the yarn tube can be looped and wrapped around the brush 10 during the rotation. Then, when the moving mechanism 30 drives the rotating mechanism 20 to move the brush 10 away from the yarn tube to the separation position, the thread ends can be separated from the surface of the yarn tube with the brush 10, thus completing the thread finding work.

[0041] The brush head finding device 100 of this application, by setting a brush 10, allows the yarn on the surface of the bobbin to easily adhere to the brush 10. Furthermore, since the yarn ends can be looped and wrapped around the brush 10, they are less likely to fall off, thus improving the overall success rate of head finding. In addition, the brush 10 has multiple head finding areas AA along the direction of the first axis of rotation, each area AA corresponding to one bobbin. Therefore, the same brush 10 can simultaneously find the heads of multiple bobbins, improving the efficiency of head finding and reducing the cost of setting multiple brushes 10. Moreover, since there is only one brush 10, only one brush 10 needs to be cleaned periodically, thus improving cleaning efficiency.

[0042] In an embodiment of this application, the first rotating shaft is perpendicular to the axis of the bobbin located at the head-finding station.

[0043] In other words, if the yarn tube is placed vertically at the head-finding station, the brush 10 is placed horizontally and in contact with the yarn tube.

[0044] Therefore, during the rotation of the brush 10 around the first axis, its rotation direction is perpendicular to the winding direction of the yarn surface, which makes it easier to find the yarn end and improves the accuracy of finding the end.

[0045] It should also be noted that, because the brush 10 is placed horizontally, it can only contact a certain segment of the outer surface of the yarn tube along its axial direction to locate the yarn end located on that segment. In this way, the area of ​​the yarn end locating region AA can be reduced, and the yarn end locating efficiency can be improved.

[0046] In the embodiments of this application, the brush head finding device 100 further includes an air blowing mechanism 35, which is disposed on one side of the brush 10 in a direction perpendicular to the first rotating axis. The air blowing mechanism 35 is used to blow air onto the bobbin located at the head finding station in the direction of the brush 10.

[0047] The direction perpendicular to the first axis of rotation is referred to here as the vertical direction.

[0048] Since the air blowing mechanism 35 blows air towards the brush 10, the airflow can blow the yarn end of the tube towards the brush 10 to the corresponding position of the tube, thus making it easier for the brush 10 to find the yarn end during rotation.

[0049] Specifically, the air blowing mechanism 35 is arranged vertically on the lower side of the brush 10. In this way, when the air blowing mechanism 35 blows air towards the brush 10, it can blow the drooping yarn ends of the bobbin upward to the upper half of the bobbin, thereby making it easier for the brush 10 to pick up the yarn ends from above.

[0050] It should also be noted that the air blowing mechanism 35 is connected to the moving mechanism 30, which provides the driving force to move the rotating mechanism 20 and the air blowing mechanism 35 simultaneously. In this way, the air blowing mechanism 35 can maintain a positional relationship with the brush 10, thereby accurately finding the yarn head.

[0051] In the embodiments of this application, the air blowing mechanism 35 includes a plurality of air blowing parts 351, the number of air blowing parts 351 being the same as the number of head finding areas AA, and each air blowing part 351 being disposed on one side of a corresponding head finding area AA of the brush 10 along a direction perpendicular to the first rotating axis, and each air blowing part 351 being used to blow air onto a corresponding bobbin located at the head finding station in the direction of the brush 10.

[0052] Specifically, all the air blowing parts 351 can be located vertically below the brush 10, and each air blowing part 351 is spaced apart from each other in the horizontal direction.

[0053] By setting multiple air blowing sections 351, air can be blown onto the yarn ends of multiple yarn tubes simultaneously, which makes it easier for the brush 10 to find the yarn ends of multiple yarn tubes during rotation, thus improving the yarn end finding efficiency.

[0054] Optionally, the number of yarn-finding zones AA is three, and the number of air-blowing sections 351 is also three. In this way, air can be blown onto the yarn ends of three drooping yarn tubes at the same time, and the brushes 10 can simultaneously find the yarn ends of the three yarn tubes.

[0055] In some embodiments, the blowing section 351 is configured as a spherical nozzle.

[0056] A spherical nozzle is a fluid nozzle that allows for multi-angle adjustment through a spherical joint.

[0057] Therefore, when the air blowing section 351 is constructed as a universal ball nozzle, the air blowing direction can be adjusted according to the actual situation, and the air blowing direction can be more precise, making it easier to find the yarn end of the tube and further improving the success rate of finding the end.

[0058] In some embodiments, the brush head finding device 100 further includes an air blowing adjustment mechanism 38, which is movably connected to the air blowing mechanism 35 and is used to adjust the distance between the air blowing mechanism 35 and the brush 10 in a direction perpendicular to the first axis of rotation.

[0059] Since the yarn tubes are of different types, the distance between the air blowing mechanism 35 and the brush 10 in the direction perpendicular to the first rotating axis can be adjusted by the air blowing adjustment mechanism 38. This makes it easier to find the yarn ends of the yarn tubes and further improves the success rate of finding the ends.

[0060] Specifically, the air blowing adjustment mechanism 38 includes an adjustment screw 381, and the air blowing mechanism 35 has an adjustment hole 352. The adjustment hole 352 extends in a direction perpendicular to the first rotating shaft, and the adjustment screw 381 passes through the adjustment hole 352 and is movable in the extending direction of the adjustment hole 352.

[0061] More specifically, the brush head finding device also includes a mounting base 40, a rotating mechanism 20 mounted on the mounting base 40, and an air blowing mechanism 35 fixed to the mounting base 40 by an adjusting screw 381.

[0062] Thus, by removing the adjusting screw 381, moving the air blowing mechanism 35 in a direction perpendicular to the first rotating shaft, and then installing the adjusting screw 381 onto the mounting base 40, the position of the air blowing mechanism 35 in a direction perpendicular to the first rotating shaft can be adjusted.

[0063] In some embodiments, the rotating mechanism 20 is connected to one end of the first rotating shaft of the brush 10, and the other end of the first rotating shaft is suspended.

[0064] Since the brush 10 on the rotating mechanism 20 is in contact with the yarn tube, the reverse force from the yarn tube is not large. Therefore, the rotating mechanism 20 is only connected to one end of the first rotating shaft of the brush 10, which ensures that the brush 10 finds its head smoothly and simplifies the overall structure.

[0065] In addition, the simplified rotary drive method also reduces the frequency of cleaning the rotary mechanism 20.

[0066] In some embodiments, the rotating mechanism 20 includes a rotating drive 21 and a belt pulley transmission mechanism 22, wherein the rotating drive 21 is connected to the first rotating shaft of the brush 10 via the belt pulley transmission mechanism 22.

[0067] The belt pulley transmission mechanism 22 refers to a mechanism in which the driving pulley drives the belt to move through the friction of the belt, and the belt then drives the driven pulley to rotate through the friction.

[0068] By setting a belt pulley transmission mechanism 22 to connect the rotary drive component 21 and the brush 10, the belt elasticity can absorb impact loads, reduce operating noise and vibration, and the structure is simple with low installation and commissioning costs.

[0069] In other embodiments, a gear drive mechanism or a chain drive mechanism may be used instead.

[0070] Specifically, the brush 10 and the rotary drive 21 are both mounted on the first side of the mounting base 40. The first rotating shaft of the brush 10 and the output shaft of the rotary drive 21 are both passed through the mounting base 40 to the second side of the mounting base 40 opposite to the first side. The belt pulley transmission mechanism 22 is located on the second side and is connected to the first rotating shaft of the brush 10 and the output shaft of the rotary drive 21.

[0071] In the embodiments of this application, both the air blowing mechanism 35 and the air blowing adjustment mechanism 38 are mounted on the mounting base 40.

[0072] In some embodiments, the moving mechanism 30 includes a moving drive 31 and a moving guide rail 32. The brush 10 and the rotating mechanism 20 are both mounted on the mounting base 40. The mounting base 40 is slidably engaged with the moving guide rail 32. The moving drive 31 is connected to the mounting base 40 and is used to provide a driving force to move the mounting base 40.

[0073] By setting the sliding guide rail 32 and the mounting base 40 to slide together, the brush 10 can move more smoothly and move more precisely.

[0074] Specifically, the movable guide rail 32 includes at least two sub-guide rails 321, which are spaced apart from each other along a direction parallel to the first axis of rotation of the brush 10, and the mounting base 40 is slidably engaged with all the sub-guide rails 321.

[0075] Based on the same inventive concept, this application also provides a yarn-feeding robot, including the brush head-finding device 100 in any of the above embodiments.

[0076] Specifically, the brush head finding device 100 also includes a yarn take-up mechanism and a yarn gripping robotic arm. The yarn take-up mechanism can pick up the yarn that has been found by the brush head finding device 100, and the yarn gripping robotic arm is used to grip the yarn and pick up the yarn that has been picked up by the yarn take-up mechanism.

[0077] In practical applications, after the brush 10 is in contact with the yarn tube and rotates around the first axis to complete the head finding work, the moving mechanism 30 drives the rotating mechanism 20 to move the brush 10 away from the yarn tube. The brush 10 rotates in the opposite direction to release a certain length of the found yarn, so that the yarn can be lightly hung on the brush without falling off, making it convenient for the subsequent yarn take-up mechanism to pick it up.

[0078] The brush head finding device 100 with multiple head finding areas and the yarn feeding robot provided in this application embodiment have the following advantages compared with the prior art:

[0079] By setting up the brush 10, the yarn on the surface of the bobbin can easily adhere to the brush 10. Furthermore, since the yarn ends can be looped around the brush 10, they are less likely to fall off, thus improving the overall success rate of yarn head finding. In addition, the brush 10 has multiple yarn head finding areas AA along the direction of the first axis of rotation, each area AA corresponding to one bobbin. Therefore, the same brush 10 can simultaneously find the yarn heads of multiple bobbins, improving the efficiency of yarn head finding and reducing the cost of setting up multiple brushes 10. Moreover, since there is only one brush 10, only one brush 10 needs to be cleaned periodically, thus improving cleaning efficiency.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
