Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and in particular to a tail yarn removal device and a yarn feeding robot based on airflow assistance. Background Technology

[0002] With the development of the textile industry and the advancement of technology, the degree of automation in textiles is becoming increasingly higher, and yarn feeding robots that can automatically pick up yarn tubes, extract thread ends, and put yarn into the yarn storage have emerged.

[0003] In related technologies, yarn feeding robots typically employ a non-collective doffing process. Therefore, each yarn bobbin usually has tail yarn of varying lengths left at its bottom. If not handled promptly, this tail yarn will wrap around the normal yarn and attach to the bobbin, effectively adding impurities and affecting production quality. However, the tail yarn handling methods in these technologies suffer from the inability to effectively remove the tail yarn within the processing channel, resulting in low tail yarn handling efficiency. Utility Model Content

[0004] Therefore, it is necessary to address the problem that the tail yarn in the related technology cannot be effectively removed in the processing channel, resulting in low tail yarn processing efficiency, and to provide a tail yarn removal device and yarn feeding robot based on airflow assistance that can improve tail yarn processing efficiency.

[0005] One aspect of this application provides a tail yarn removal device based on airflow assistance, comprising:

[0006] The blower mechanism has a yarn tail processing channel and a blowing channel. The yarn tail processing channel is used to receive the yarn tail of the bobbin, and one end of the blowing channel has an air outlet formed on the inner wall of the yarn tail processing channel. The blowing channel is used to provide airflow.

[0007] The wire-cutting mechanism is movable relative to the blower mechanism;

[0008] The thread-cutting mechanism includes a thread-cutting position during its operation. When in the thread-cutting position, the thread-cutting mechanism cuts the tail yarn located in the tail yarn processing channel.

[0009] The aforementioned tail yarn removal device based on airflow assistance can maintain the yarn tube in a certain posture through the airflow provided by the airflow in the tail yarn processing channel after receiving the tail yarn of the tube yarn in the tail yarn processing channel. This allows the yarn tube yarn to be reliably cut by the yarn cutting mechanism in the tail yarn processing channel, thus improving the reliability of tail yarn processing.

[0010] In one embodiment, the blowing channel includes multiple blowing channels, and one end of each blowing channel forms an air outlet on the inner wall of the tail yarn processing channel. The air outlets are spaced apart from each other along the circumference of the tail yarn processing channel.

[0011] In one embodiment, the yarn tail processing channel has a yarn tail inlet and a yarn tail outlet, and the air blowing channel is inclined toward the yarn tail outlet relative to the axial direction of the yarn tail processing channel.

[0012] In one embodiment, the blower mechanism further includes a connecting channel surrounding the tail yarn processing channel, with the ends of each blower channel away from the tail yarn processing channel connected to each other via the connecting channel.

[0013] In one embodiment, the yarn tail processing channel has a yarn tail inlet and a yarn tail outlet, and the yarn cutting mechanism is positioned closer to the yarn tail inlet than the air outlet.

[0014] In one embodiment, a cavity is provided on the sidewall of the yarn tail processing channel for at least a portion of the yarn cutting mechanism to extend into the yarn tail processing channel.

[0015] In one embodiment, the thread-cutting mechanism includes a fixed blade and a movable blade, at least a portion of the fixed blade being fixed within a cavity, and the movable blade being movable relative to the fixed blade and capable of extending into the tail yarn processing channel during movement.

[0016] In one embodiment, there are multiple blower mechanisms and wire-cutting mechanisms, with each blower mechanism corresponding to a wire-cutting mechanism.

[0017] In one embodiment, the tail yarn removal device further includes a yarn return box, which includes a yarn return chamber that is connected to the tail yarn processing channel for collecting the cut tail yarn.

[0018] Another aspect of this application provides a yarn-feeding robot, including the tail yarn removal device based on airflow assistance in any of the above embodiments.

[0019] The aforementioned yarn feeding robot, after receiving the tail yarn from the bobbin in the tail yarn processing channel, can maintain the bobbin in a certain posture through the airflow provided by the air blowing channel, thereby reliably being cut by the yarn cutting mechanism in the tail yarn processing channel, thus improving the reliability of tail yarn processing.

[0034] Figure 1 This is a schematic diagram of the structure of a tail yarn removal device based on airflow assistance in one or more embodiments of this application; Figure 2 for Figure 1 The diagram shows a partial structure of the yarn removal device assisted by airflow. Figure 3 for Figure 2The diagram shows an enlarged view of part A in the tail yarn removal device assisted by blowing airflow.

[0035] See Figures 1-3 This application provides an embodiment of a yarn removal device 100 based on airflow assistance, which includes a blower mechanism 10 and a yarn cutting mechanism 20. The yarn removal device 100 of this application embodiment can be applied to yarn feeding robots or other devices suitable for yarn removal.

[0036] Combination Figure 6 The blower mechanism 10 has a yarn tail processing channel 11 and a blowing channel 12. The yarn tail processing channel 11 is used to receive the yarn tail of the bobbin. One end of the blowing channel 12 forms an air outlet 121 on the inner wall of the yarn tail processing channel 11, and the blowing channel 12 is used to provide airflow. The thread cutting mechanism 20 is movable relative to the blower mechanism 10. The thread cutting mechanism 20 includes a thread cutting position during its movement. When in the thread cutting position, the thread cutting mechanism 20 cuts the yarn tail located in the yarn tail processing channel 11.

[0037] The tail yarn processing channel 11 refers to the channel for processing tail yarns. Before processing the tail yarns, the tail yarns of the bobbins to be processed are received by the tail yarn processing channel 11. The tail yarn processing channel 11 can receive the tail yarns of the bobbins using other mechanical structures, such as a robotic arm that moves the bobbins above the tail yarn processing channel 11 so that the tail yarns can automatically fall into the tail yarn processing channel 11. In other embodiments, other methods can also be applied, such as blowing, adsorption, or manual methods to make the tail yarns be received by the tail yarn processing channel 11. Specifically, in the embodiment of this application, the bobbins are first moved above the tail yarn processing channel 11 by a robotic arm, and then moved downward so that the depth of the tail yarn end is lower than the air outlet 121 of the blowing channel 12, ensuring that a sufficiently long tail yarn of the bobbins falls into the tail yarn processing channel 11.

[0038] The air blowing channel 12 can supply airflow to the tail yarn processing channel 11 by connecting to an air source. A connecting pipe can be provided between the air source and the air blowing channel 12, and a solenoid valve can be installed on the connecting pipe to open or close the connection between the air blowing channel 12 and the air source. The tail yarn hanging into the tail yarn processing channel can maintain a certain posture after being blown by the airflow and will not be disturbed by the external environment.

[0039] Before the yarn tail processing channel 11 receives the yarn tail, the yarn cutting mechanism 20 should not obstruct the yarn tail processing channel 11 from receiving the yarn tail. The yarn cutting mechanism 20 can extend into the yarn tail processing channel 11 to cut the yarn tail.

[0040] Therefore, the tail yarn removal device 100 based on airflow assistance in this application embodiment can maintain the yarn in the tail yarn processing channel 11 in a certain posture by the airflow provided by the airflow provided by the airflow channel 12 after receiving the tail yarn of the tube yarn in the tail yarn processing channel 11, so that the yarn in the tube yarn processing channel 11 can be reliably cut by the yarn cutting mechanism 20 in the tail yarn processing channel 11, thus improving the reliability of tail yarn processing.

[0041] Specifically, in the embodiments of this application, the tail yarn removal device 100 also includes a base 30, and the blower mechanism 10 and the thread cutting mechanism 20 are all disposed on the base 30.

[0042] The blower mechanism 10 includes a first part 13 and a second part 14, which are joined together vertically. A tail yarn processing channel 11 extends through both the first part 13 and the second part 14, with a blower channel 12 located on the second part 14. The tail yarn processing channel 11 can extend vertically, and its cross-sectional shape can be circular, square, or other shapes.

[0043] In some embodiments, the blowing channel 12 includes a plurality of blowing channels, and one end of each blowing channel 12 forms an air outlet 121 on the inner wall of the tail yarn processing channel 11. Each air outlet 121 is arranged at intervals from each other along the circumference of the tail yarn processing channel 11.

[0044] In other words, when each air blowing channel 12 blows air at the same time, the yarn tube can be kept as close as possible to the middle of the tail yarn processing channel 11 and away from the inner wall of the tail yarn processing channel 11, so as to facilitate the yarn cutting mechanism 20 to cut the tail yarn.

[0045] Specifically, each air outlet 121 is centrally symmetrically distributed along the central axis of the tail yarn processing channel 11. In this way, the yarn tubes located in the tail yarn processing channel 11 can be subjected to the same wind force in all directions, thereby maintaining them in the central position of the tail yarn processing channel 11.

[0046] In addition, the air outlet 121 of this embodiment has a small opening so as to provide a large flow rate of air into the tail yarn processing channel 11, thereby enabling the yarn tube to be reliably stressed in all directions and reliably maintained in its current posture.

[0047] See Figures 4-6 Furthermore, the tail yarn processing channel 11 has a tail yarn inlet 111 and a tail yarn outlet 112, and the air blowing channel 12 is inclined relative to the axial direction of the tail yarn processing channel 11 toward the tail yarn outlet 112.

[0048] The tail yarn inlet 111 is the inlet for receiving tail yarn in the tail yarn processing channel 11, and the tail yarn outlet 112 is the outlet for discharging the cut tail yarn.

[0049] When the air blowing channel 12 is inclined relative to the axis of the tail yarn processing channel 11 toward the tail yarn outlet 112, it can provide a force to blow the tail yarn toward the tail yarn outlet 112, reducing the risk that the tail yarn will be blown away from the tail yarn processing channel 11 by the air blowing from the tail yarn inlet 111, and improving the reliability of subsequent tail yarn cutting.

[0050] Furthermore, when each air outlet 121 is centrally symmetrically distributed along the central axis of the tail yarn processing channel 11, the downward-sloping airflow provided by the air blowing channel 12 can also keep the tail yarn in a relatively vertical posture, further improving the reliability of subsequent tail yarn cutting.

[0051] In some embodiments, the blower mechanism 10 further includes a connecting channel 15 surrounding the tail yarn processing channel 11, and the other ends of each blower channel 12 away from the tail yarn processing channel 11 are connected to each other through the connecting channel 15.

[0052] By setting up the connecting channel 15, the airflow of each blowing channel 12 can be the same, thereby making the wind force from each blowing channel 12 on the tail yarn the same, reducing the instability of the tail yarn under force, and improving the reliability of subsequent tail yarn cutting.

[0053] Specifically, the connecting channel 15 is disposed on the second part 14, which includes a first sealing part 141 and a second sealing part 142. The first sealing part 141 and the second sealing part 142 are joined together to form an annular connecting channel 15 between them. Optionally, an annular sealing strip is also provided between the first sealing part 141 and the second sealing part 142. The annular sealing strip is used to seal the connecting channel 15 to prevent airflow in the connecting channel 15 from flowing to the outside through the fitting gap between the first part 13 and the second part 14. Specifically, there are two annular sealing strips, which are spaced apart from each other along the axial direction of the tail yarn processing channel 11, and the connecting channel 15 is disposed between the two annular sealing strips.

[0054] In the embodiments of this application, the thread cutting mechanism 20 is positioned closer to the tail yarn inlet 111 than the air outlet 121.

[0055] Since the tail yarn in the tail yarn processing channel 11 maintains a certain posture after passing through the airflow blown by the air outlet 121, and the upper end of the tail yarn is connected to the bobbin, the section from the bobbin to the end of the tail yarn has a certain posture. Therefore, by setting the yarn cutting mechanism 20 closer to the tail yarn inlet 111 relative to the air outlet 121, the tail yarn with a certain posture can be cut without affecting the airflow, thus improving the reliability of tail yarn cutting.

[0056] Combination Figure 1 and Figure 6In some embodiments, a cavity 16 is provided on the side wall of the tail yarn processing channel 11, and the cavity 16 is used for at least a portion of the yarn cutting mechanism 20 to extend into the tail yarn processing channel 11.

[0057] By directly creating a recess 16 on the side wall of the yarn tail processing channel 11, the yarn cutting mechanism 20 can be stored in the recess 16 when not in use, thus not obstructing the yarn tail processing channel 11 from receiving the yarn tail. Furthermore, when it is necessary to cut the yarn tail, the yarn cutting mechanism 20 can quickly extend from the side of the recess 16 into the yarn tail processing channel 11, achieving rapid cutting and improving cutting reliability.

[0058] It should be noted that when the tail yarn processing channel 11 receives the tail yarn, the thread cutting mechanism 20 should be in the open state, while when cutting the tail yarn, the thread cutting mechanism 20 should be in the near-closed state or in the closed state.

[0059] In a specific embodiment of this application, the cavity 16 is arranged around the sidewall of the entire tail yarn processing channel 11. Specifically, the cavity 16 is formed between the first part 13 and the second part 14, and the thread cutting mechanism 20 can be installed on the second part 14.

[0060] Combination Figure 1 , Figure 3 and Figure 6 In some embodiments, the thread cutting mechanism 20 includes a fixed blade 21 and a movable blade 22. At least a portion of the fixed blade 21 is fixed in the cavity 16, and the movable blade 22 is movable relative to the fixed blade 21 and can extend into the tail yarn processing channel 11 during movement.

[0061] Specifically, the fixed blade 21 is fixed to the second part 14, and one end of the movable blade 22 is rotatably connected to one end of the fixed blade 21.

[0062] Specifically, the wire cutting mechanism 20 also includes a wire cutting cylinder 23, the output end of which is connected to the movable blade 22 so that the movable blade 22 moves relative to the fixed blade 21 through telescopic movement.

[0063] In the embodiments of this application, there are multiple blower mechanisms 10 and wire cutting mechanisms 20, with each blower mechanism 10 corresponding to a wire cutting mechanism 20.

[0064] This allows for the simultaneous cutting of the tail yarns from multiple yarn tubes, improving tail yarn processing efficiency.

[0065] Optionally, the number of blower mechanism 10 and wire cutting mechanism 20 are three, four, or six, etc.

[0066] Specifically, all the blower mechanisms 10 can be arranged side by side on the same straight line, and the movable blades 22 of each wire cutting mechanism 20 can be connected to the output end of the same wire cutting cylinder 23 through the same connecting rod 24, so that under the action of the wire cutting cylinder 23, they can jointly cut the tail yarn of each bobbin.

[0067] In the embodiments of this application, the tail yarn removal device 100 further includes a yarn return box 40, which includes a yarn return cavity 41. The yarn return cavity 41 is connected to the tail yarn processing channel 11 and is used to collect the cut tail yarn.

[0068] By setting up a return box 40, the cut yarn tails can be collected, preventing the torn yarn tails from scattering and affecting the operation of the device, and facilitating subsequent cleaning.

[0069] Specifically, the return yarn box 40 is located vertically below the blower mechanism 10, and the return yarn chamber 41 is connected to the tail yarn outlet 112 of the tail yarn processing channel 11.

[0070] In a specific embodiment of this application, the yarn return box 40 also has a transparent window. By setting the transparent window, the yarn tail collected in the yarn return chamber 41 can be identified by human eye, so that when the yarn tail in the yarn return chamber 41 is full, the user can clean the yarn tail in the yarn return chamber 41.

[0071] In addition, the rewind box 40 includes a box body and a door. One side of the box body has an opening that communicates with the rewind cavity 41. The door is installed on the box body and can open or close the opening.

[0072] When the yarn tail in the return chamber 41 is full, the user can open the door to clean the yarn tail in the return chamber 41.

[0073] Based on the same inventive concept, this application also provides a yarn-feeding robot, including the tail yarn removal device 100 based on airflow assistance in any of the above embodiments.

[0074] After receiving the yarn tail from the bobbin in the yarn tail processing channel 11, the yarn tail in the bobbin can be kept in a certain posture by the airflow provided by the air blowing channel 12, so that it can be reliably cut by the yarn cutting mechanism 20 in the yarn tail processing channel 11, thus improving the reliability of yarn tail processing.

[0075] Specifically, the yarn feeding robot also includes a robotic arm that can move relative to the tail yarn removal device 100 to move the bobbin yarn above the tail yarn removal device 100.

[0076] In addition, after the tail yarn is cut off by the tail yarn removal device 100, the robotic arm can move to the yarn feeding position to feed the yarn.

[0077] It should also be noted that, in the embodiments of this application, during the process of the tail yarn removal device 100 processing the tail yarn, the robotic arm can maintain the clamping of the tube yarn until it moves to the yarn feeding position for complaint processing.

[0078] 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.

[0079] 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 application. 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.
