Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0052] The textile equipment can adopt negative pressure suction nozzle filament separating device and lease separating filament separating device to process the silk thread respectively. Taking the textile equipment as the heald inserting equipment for example, the negative pressure suction nozzle filament separating device mainly generates negative pressure airflow at the suction head through the vacuum generator, so that the silk thread is quickly separated from the silk screen to the target position. In this process, the silk thread tension changes very sharply, and the silk thread is easy to be separated from the suction head, which greatly affects the silk taking efficiency. At the same time, if the movement stroke of the adsorbed silk thread is too long, the silk thread is also easy to be separated from the suction head. In addition, the lease separating filament separating device mainly separates the silk thread into single root through the lease separating device and isolates it with the lease line. In the related technology, the negative pressure suction nozzle filament separating device and the lease separating filament separating device are two independent devices, which need to switch different devices for operation corresponding to different use scenes, thereby increasing the cost and reducing the production efficiency.
[0053] In view of this, referring to Figures 1-10 , an embodiment of the utility model provides a yarn taking device 100 for obtaining one of a plurality of silk threads 200 located at a storage position. Among them, the silk thread 200 can be any type of silk thread 200 used for weaving, for example, the silk thread 200 can be a yarn used to make a textile product, in addition, the storage position is a position for placing a plurality of yarns, specifically, the yarn taking device 100 can be used with a creel, the creel can be connected to a plurality of yarns, at this time, the storage position is the position of the creel suitable for connecting the yarn. In some embodiments, the yarn taking device 100 can be used as a stand-alone device, when there is a yarn taking demand, the yarn taking device 100 can be placed in the corresponding position for taking yarn, which can make the use flexibility of the yarn taking device 100 higher; in another embodiment, the yarn taking device 100 can be used as a component of a complete set of any suitable type of textile equipment, for example, the yarn taking device 100 can be used as a component of a heald inserting machine or a heald inserting machine, which can make the integration of the textile equipment higher and the function more integrated. The yarn taking device 100 comprises a negative pressure suction nozzle module 110, a lease separating filament separating module 120 and a driving module 130.
[0054] Referring to Figures 1-2 The negative pressure nozzle module 110 is capable of generating a negative pressure airflow to suck the yarn 200. The negative pressure nozzle module 110 can generate a negative pressure capable of sucking the yarn 200 in any suitable form. For example, in some embodiments, the negative pressure nozzle module 110 defines a slit and a negative pressure channel adapted to pass gas in the first direction X, one side of the slit has an opening, and the other side is communicated with the negative pressure channel, so that the yarn 200 can enter the slit through the opening. In order to pass other negative pressure, the negative pressure nozzle module 110 can include a vacuum generator (or the negative pressure nozzle module 110 is adapted to be connected to a vacuum generator), which is communicated with the negative pressure channel, so that the yarn 200 can be sucked into the slit. By designing the shape, size and position of the slit, the yarn 200 can be more easily sucked into the slit by the negative pressure nozzle module 110 at one time, and the yarn 200 can be more stably located in the slit and not easily detached.
[0055] Referring to Figures 1-2 The dividing module 120 includes a dividing structure 121 and a yarn taking part 122. The dividing structure 121 is used to connect a dividing line 300, and the dividing line 300 is used to separate a plurality of yarns 200. The dividing structure 121 can be any structure suitable for connecting the dividing line 300. In some embodiments, the dividing module 120 can include the dividing line 300. The specific function of the dividing line 300 can be that before the warp insertion operation, the dividing line 300 is inserted into the warp layer, and the originally interwoven and close yarns are separated by a bundle or a single root according to a certain rule.
[0056] Referring to Figures 3-4The driving module 130 comprises a first driving part 131 and a second driving part 132, the first driving part 131 is configured to drive the negative pressure suction nozzle module 110 and the separating and dividing module 120 to move relative to each other along the first direction X, and the second driving part 132 is configured to drive the separating and dividing module 120 to rotate along the circumferential direction R around the first direction X, so that the wire taking part 122 can hook the yarn 200. The wire taking part 122 itself can have any structure suitable for hooking the yarn 200 under the circumferential direction R movement, which is not limited here. According to the above movement, in some embodiments, the first driving part 131 can be a linear motion motor, and the second driving part 132 can be a rotating motor. According to the requirements, under a type of driving arrangement, the first driving part 131 can drive the negative pressure suction nozzle module 110 to approach the yarn 200, or drive the separating and dividing module 120 to approach the yarn 200, or can simultaneously drive the negative pressure suction nozzle module 110 and the separating and dividing module 120 to approach the yarn 200; under another type of driving arrangement, the first driving part 131 can only drive the negative pressure suction nozzle module 110 to approach the yarn 200; under still another type of driving arrangement, the first driving part 131 can only drive the separating and dividing module 120 to approach the yarn 200.
[0057] It should be noted that according to different requirements, the action of the negative pressure suction nozzle module 110 to adsorb the yarn 200 can correspond to adsorbing the yarn 200 located at the storage position, or can correspond to adsorbing the yarn 200 that has been hooked from the storage position by the separating and dividing module 120 (at this time the yarn 200 can not be at the storage position), similarly, the action of the separating and dividing module 120 to adsorb the yarn 200 can correspond to hooking the yarn 200 located at the storage position, or can correspond to hooking the yarn 200 that has been adsorbed from the storage position by the negative pressure suction nozzle module 110 (at this time the yarn 200 can not be at the storage position).
[0058] According to the first driving part 131 and the second driving part 132 arranged above, on one hand, through the driving action of the first driving part 131 along the first direction X, the negative pressure suction nozzle module 110 and one of the yarn separating and dividing module 120 that needs to approach and obtain the yarn 200 can be retracted along the first direction X, so that the position interference phenomenon between the negative pressure suction nozzle module 110 and the yarn separating and dividing module 120 does not occur. On the other hand, through the driving action of the second driving part 132 along the circumferential direction R, the yarn separating and dividing module 120 can play the role of hooking and avoiding according to the action demand. Specifically, in one case of hooking the yarn 200, the yarn separating and dividing module 120 needs to hook the yarn 200 located at the storage position. At this time, the second driving part 132 can drive the yarn separating and dividing module 120 to rotate to a position capable of avoiding the yarn 200, so that the first driving part 131 can drive the yarn separating and dividing module 120 along the first direction X, and the yarn taking part 122 moves to the upper or lower of the yarn 200, and after reaching the specified position, the second driving part 132 can further drive the yarn separating and dividing module 120 to rotate to a position capable of hooking the yarn 200. Thereafter, the next step of processing the hooked yarn 200 can be performed through the driving action of the first driving part 131 or the driving action of the second driving part 132 or other driving actions. In another case of hooking the yarn 200, the yarn separating and dividing module 120 needs to hook the yarn 200 that has been adsorbed by the negative pressure suction nozzle module 110 and has left the storage position. At this time, the second driving part 132 can drive the yarn separating and dividing module 120 to rotate to a position capable of avoiding the yarn 200, so that the first driving part 131 can drive the yarn separating and dividing module 120 along the first direction X, and the yarn taking part 122 moves to the upper or lower of the yarn 200. Thereafter, the next step of processing the hooked yarn 200 can be performed through the driving action of the first driving part 131 or the driving action of the second driving part 132 or other driving actions.
[0059] It can be seen that the yarn taking device 100 of the utility model includes a negative pressure suction nozzle module 110, a separating and separating filament module 120 and a driving module 130. The negative pressure suction nozzle module 110 can generate a negative pressure airflow to adsorb the filament 200. The separating and separating filament module 120 includes a separating structure 121 and a filament taking part 122, the separating structure 121 is used to connect a separating line 300, and the separating line 300 is used to separate a plurality of filaments 200. The driving module 130 includes a first driving part 131 and a second driving part 132, the first driving part 131 is configured to drive the negative pressure suction nozzle module 110 and the separating and separating filament module 120 to move relatively along a first direction X, and the second driving part 132 is configured to drive the separating and separating filament module 120 to rotate along a circumferential direction R around the first direction X, so that the filament taking part 122 can hook the filament 200. Compared with the design of the prior art, the negative pressure suction nozzle separating filament device and the separating and separating filament device are two independent devices respectively, in the scheme of the utility model, on the one hand, through the driving effect of the first driving part 131 along the first direction X, when one of the negative pressure suction nozzle module 110 and the separating and separating filament module 120 needs to be close to and obtain the filament 200, the other one can retract along the first direction X, so that the negative pressure suction nozzle module 110 and the separating and separating filament module 120 will not interfere with each other. On the other hand, through the driving effect of the second driving part 132 along the circumferential direction R, the separating and separating filament module 120 can play the role of hooking and avoiding according to the action requirement. Therefore, the yarn taking device 100 of the utility model can be compatible with the negative pressure suction nozzle module 110 and the separating and separating filament module 120, and the movement of the two is more flexible and does not interfere with each other.
[0060] For the specific driving effect of the second driving part 132, see Figures 2-4In some embodiments, the second driving part 132 is configured to drive the separating and dividing module 120 to switch between the first position, the second position and the third position in sequence. In addition, the yarn 200 in the storage position is defined to extend along a second direction Y perpendicular to the first direction X, and the above-mentioned extending direction is the overall extending direction, that is, the influence of the bending of the yarn 200 itself needs to be excluded. In some embodiments, the first direction X and the second direction Y are both horizontally extending directions. Based on the above definition, in some embodiments, when the separating and dividing module 120 is in the first position and the separating thread 300 is connected to the separating structure 121, the separating thread 300 can separate a plurality of yarns 200. At this time, since the separating thread 300 needs to perform the separating action, the negative pressure suction nozzle module 110 and the separating and dividing module 120 can not work at the same time. In addition, when viewed along the first direction X, the separating and dividing module 120 can at least partially overlap with the yarn 200. When the separating and dividing module 120 is in the second position, viewed along the first direction X, the separating and dividing module 120 is spaced apart from the yarn 200, that is, the movement of the separating and dividing module 120 along the first direction X will not interfere with the yarn 200. The first driving part 131 can drive the yarn taking part 122 to move above or below the yarn 200. Then, the separating and dividing module 120 can be switched from the second position to the third position. When the separating and dividing module 120 is in the third position, viewed along the first direction X, the yarn taking part 122 at least partially overlaps with the yarn 200. While the separating and dividing module 120 stays in the third position, the first driving part 131 can drive the separating and dividing module 120 to move away from the storage position again, so that the yarn taking part 122 can hook the yarn 200 away from the storage position.
[0061] The number and position of the separating and dividing module 120 can be set according to specific needs. Specifically, see Figures 7-8 In a type of setting, the number of the separating and dividing module 120 is two. Along a direction perpendicular to the first direction X, the two separating and dividing modules 120 are respectively located on the two sides of the negative pressure suction nozzle module 110. The second driving part 132 is configured to drive the two separating and dividing modules 120 to simultaneously rotate along the circumferential direction R. When the separating and dividing module 120 is in the second position, along a third direction Z perpendicular to the first direction X and the second direction Y, the two separating and dividing modules 120 are staggered and respectively located on the two sides of the yarn 200. The setting of the two separating and dividing modules 120 can make the hooking action more reliable, and the yarn 200 is less likely to be separated. In addition, see Figures 7-8When the number of the separating and dividing modules 120 is two, the negative pressure suction nozzle module 110 (specifically, the end for suctioning the yarn 200) can be closer to one of the separating and dividing modules 120 in the direction perpendicular to the first direction X. In the case where the two separating and dividing modules 120 are staggered and located on the two sides of the yarn 200 respectively to hook the yarn 200, the force bearing condition of the yarn 200 can be balanced by adjusting the position of the negative pressure suction nozzle module 110, so that the two separating and dividing modules 120 apply force to the two ends of the yarn 200 more balancedly, and the yarn 200 is less likely to be bent excessively or detached. Figure 9 or Figure 10 In another type of arrangement, the number of the separating and dividing modules 120 is one, and the separating and dividing module 120 is located at the second position in the third direction Z perpendicular to the first direction X and the second direction Y, and on one side of the yarn 200. The arrangement of one separating and dividing module 120 can simplify the overall structure, and when the separating and dividing module 120 is not working, it can be spaced from the yarn 200 in the first direction X, so that the second driving part 132 does not need to drive the separating and dividing module 120 to rotate to the position avoiding the yarn 200 in the process of the negative pressure suction nozzle module 110 suctioning the yarn 200, and when it is needed to hook the yarn 200, the separating and dividing module 120 is driven to rotate around the center on its own structure again, so that only the yarn taking part 122 of the separating and dividing module 120 rotates to the position overlapping the yarn 200, and the rest of the separating and dividing module 120 is still on one side of the yarn 200.
[0062] For the rotating direction of the separating and dividing module 120, the following definition of the circumferential direction R includes the first circumferential direction R and the second circumferential direction R in opposite directions, see Figures 3-4 In some embodiments, the second driving part 132 is configured to drive the separating and dividing module 120 to switch from the first position to the second position along the first circumferential direction R, and to drive the separating and dividing module 120 to switch from the second position to the third position along the second circumferential direction R. Through the above arrangement, when it is needed to hook the yarn 200 after the second driving part 132 drives the separating and dividing module 120 to the second position avoiding the yarn 200 along the first circumferential direction R, the separating and dividing module 120 is driven to the third position along the second circumferential direction R in the opposite direction, which can make the driving stroke of the separating and dividing module 120 shorter, and the switching between the rotating positions of the separating and dividing module 120 more efficient and rapid.
[0063] See Figure 1In some embodiments, the yarn taking device 100 further comprises a photographing module 140, which is used to detect the number of yarns 200 sucked by the negative pressure suction nozzle module 110, and is also used to detect the number of yarns 200 hooked by the yarn taking part 122. According to the above-mentioned functional requirements, the photographing module 140 can be any device suitable for visual detection, and the detection action of the photographing module 140 can be taking still images or recording video images. The photographing module 140 can specifically judge whether it is a single yarn 200 by detecting the thickness of the obtained yarn 200.
[0064] Further, referring to Figures 4-5In some embodiments, the photographing module 140 comprises a first photographing part 141 and a second photographing part 142. Specifically, the first photographing part 141 and the second photographing part 142 can be two different devices for visual detection, and the types and specifications of the two can be the same or different. In addition, in some embodiments, the first driving part 131 is configured to drive the negative pressure suction nozzle module 110 to switch between the fourth position and the fifth position in sequence, and to drive the separating and separating module 120 to switch between the sixth position and the seventh position in sequence in the first direction X, and the seventh position is located on the side away from the storage position of the fifth position. Based on this, when the negative pressure suction nozzle module 110 is located at the fourth position, the negative pressure suction nozzle module 110 can adsorb the silk thread 200 located at the storage position, when the negative pressure suction nozzle module 110 is located at the fifth position, the first photographing part 141 can detect the number of silk threads 200 adsorbed by the negative pressure suction nozzle module 110, when the separating and separating module 120 is located at the sixth position, the silk thread 200 adsorbed by the negative pressure suction nozzle module 110 at the fifth position can be hooked by the silk thread hooking part 122, and when the separating and separating module 120 is located at the seventh position, the second photographing part 142 can detect the number of silk threads 200 hooked by the silk thread hooking part 122. In some use scenarios, because the tension of the silk thread 200 changes very sharply during the process of adsorbing and driving the silk thread 200 by the negative pressure suction nozzle module 110, the silk thread 200 is easily separated from the suction head, which greatly affects the silk thread taking efficiency. Therefore, according to the design of the first photographing part 141 and the second photographing part 142 and the driving positions, when it is necessary to obtain the silk thread 200, a single silk thread 200 is first separated and adsorbed by the negative pressure suction nozzle module 110, when the negative pressure suction nozzle module 110 moves to the fifth position, the first photographing part 141 detects the number of silk threads 200 adsorbed by the negative pressure suction nozzle module 110, if it is detected that it is not a single silk thread 200, the negative pressure suction nozzle module 110 can release the silk thread 200, and the action of adsorbing the silk thread 200 by the negative pressure suction nozzle module 110 is repeated, if it is detected that a single silk thread 200 is adsorbed, the silk thread 200 adsorbed by the negative pressure suction nozzle module 110 is hooked by the separating and separating module 120 located at the sixth position, then the separating and separating module 120 further moves to the seventh position, and the second photographing part 142 further detects the number of silk threads 200 hooked by the separating and separating module 120, if it is detected that it is not a single silk thread 200, the silk thread 200 can be released, and the action of adsorbing the silk thread 200 by the negative pressure suction nozzle module 110 is repeated, if it is detected that a single silk thread 200 is adsorbed, the next operation such as manual cutting can be performed.According to the above-mentioned action process, on the one hand, the yarn 200 can be obtained by the negative pressure suction nozzle module 110 and the division and separation module 120 in relay, so as to avoid the phenomenon that the yarn 200 is easily separated after a long movement distance when the yarn 200 is only adsorbed by the negative pressure suction nozzle module 110; on the other hand, the yarn 200 obtained can be further ensured to be a single yarn 200 through the detection of the first photographing part 141 and the second photographing part 142 twice respectively.
[0065] In other embodiments, based on the first photographing part 141 and the second photographing part 142 defined in the above-mentioned embodiments, referring to Figure 6 , Figure 4 and Figure 5 , the first driving part 131 is configured to be able to drive the division and separation module 120 to switch between the eighth position, the sixth position and the seventh position in sequence. When the division and separation module 120 is located at the eighth position, the yarn taking part 122 can hook the yarn 200 located at the storage position, when the division and separation module 120 is located at the sixth position, the first photographing part 141 can detect the number of yarns 200 hooked by the yarn taking part 122, and when the division and separation module 120 is located at the seventh position, the second photographing part 142 can detect the number of yarns 200 hooked by the yarn taking part 122. It can be understood that this embodiment is similar to the above-mentioned embodiment of obtaining the yarn 200 by the negative pressure suction nozzle module 110 and the division and separation module 120 in relay, and the difference lies in that this embodiment does not need the negative pressure suction nozzle module 110 to work, but the division and separation module 120 is responsible for obtaining the yarn 200 located at the storage position. Therefore, this embodiment can correspond to the case of having a division and separation line 300, and the division and separation line 300 has already separated the single yarn 200, so it is not necessary to use the negative pressure suction nozzle module 110 to separate the single yarn 200.
[0066] In addition, referring to Figure 1 or Figure 5 , in some embodiments, the photographing module 140 includes the first photographing part 141 and the second photographing part 142, the first photographing part 141 and the second photographing part 142 are both used for detecting the number of yarns 200, the first photographing part 141 and the second photographing part 142 are spaced apart along the first direction X, and the orientation of the first photographing part 141 and the orientation of the second photographing part 142 are crossed. Through the above-mentioned setting, the spacing of the first photographing part 141 and the second photographing part 142 along the first direction X can make the setting positions of the two correspond to the positions that need to be photographed and detected by the negative pressure suction nozzle module 110 and the division and separation module 120, and the different orientations of the first photographing part 141 and the second photographing part 142 can avoid the photographing and detecting error to some extent, for example, to avoid the problem of being unable to detect or poor detection accuracy due to the existence of shielding.
