[0043] The core of the present invention is to provide an automatic yarn unloading device, which is used to reduce the labor intensity of manual labor and improve production efficiency;

[0044] Another core of the present invention is to provide a yarn unloading system having the above-mentioned automatic yarn unloading device.

[0045] like Figure 1 , Figure 2 and Figure 8As shown, the embodiment of the present invention discloses an automatic yarn unloading device, including a track portion 100, a pick-up and place portion 200, and a weighing portion 300. Among them, any two of the first track 110, the second track 120, and the third track 130 in the track portion 100 are arranged perpendicular to each other, the second track 120 is connected to the first track 110, and the second track 120 can move along the extension direction of the first track 110, and the third track 130 is connected to the second track 120, and the third track 130 can move along the extension direction of the second track 120, and the third track 130 can rotate around its own axis, thereby realizing the movement and rotation of the yarn taking tray 210 installed on the third track 130 in space. Therefore, when taking yarn, the yarn taking tray 210 can be moved to the yarn taking position through the track part 100, and the telescopic mechanism of the picking and placing part 200 is extended to make the yarn taking tray 210 move toward the yarn reel 10 in the wire drawing machine 20. At the same time, the telescopic mechanism moves along the extension direction of the third track 130, so that the yarn taking tray 210 moves to the bottom of the yarn reel 10, and then moves upward along the third track 130. The yarn taking tray 210 lifts the yarn reel 10 so that the yarn reel 10 is carried on the yarn taking tray 210. At this time, the telescopic mechanism retracts to take the yarn reel 10 on the yarn taking tray 210 out of the wire drawing machine 20, completing the yarn taking work. When it is necessary to weigh the yarn drum 10, the telescopic mechanism of the pick-up and placement section 200 continues to contract, and the yarn drum 10 on the yarn taking tray 210 is inserted into the weighing rod 310 in the weighing section 300. After the weighing rod 310 is inserted into the yarn drum 10, the lifting mechanism installed on the third track 130 drives the weighing rod 310 to move upward along the extension direction of the third track 130, and the weighing rod 310 lifts the yarn drum 10 away from the yarn taking tray 210, so that the weighing sensor weighs the yarn drum 10. After the weighing is completed, the lifting mechanism drives the weighing rod 310 to move upward along the third track 130 again. 30 moves downward to put the yarn drum 10 on the weighing rod 310 back onto the yarn taking tray 210, and then according to the weighing value, the yarn taking tray 210 moves to the corresponding yarn car 30 through the track part 100, and the position of the yarn tile 31 on the yarn car 30 is located and confirmed by the visual positioning part, and then the position of the yarn taking tray 210 is adjusted by rotating and moving the third track 130, and finally the telescopic mechanism is extended to move the yarn taking tray 210 toward the yarn tile 31, and finally the yarn drum 10 is inserted into the yarn tile 31, completing the grouping and placement of the yarn drum 10.In the automatic yarn unloading equipment provided in this embodiment, the weighing part 300 and the picking and placing part 200 are independent of each other, and the weighing sensor of the weighing part 300 is not extended into the wire drawing machine 20 along with the picking and placing part 200, so that the weighing sensor does not enter the wire drawing environment, thereby avoiding corrosion of the weighing sensor by water mist and the like in the wire drawing machine 20, improving the protection capability of the weighing sensor, ensuring that the weighing sensor has a high service life and reliability, and does not participate in the process of lifting and taking yarn, thereby ensuring the accuracy of the weighing result, and the visual recognition method improves the accuracy of positioning, thereby avoiding deviations in taking and placing materials, and the problem of equipment collision due to manual yarn placement.

[0046] like Figure 3 As shown, the pick-up and placement portion 200 provided in this embodiment is provided with a base, and the telescopic mechanism provided in this embodiment includes a first telescopic layer 230 and a second telescopic layer 240, wherein the first telescopic layer 230 is installed on the third track 130 through the base, and the base can be driven by a motor to move along the extension direction of the third track 130, and the yarn taking tray 210 is connected to the first telescopic layer 230 through the second telescopic layer 240, and the first telescopic layer 230 and the second telescopic layer 240 can both move in a direction perpendicular to the third track 130 to form a cantilever structure, so that when the yarn reel 10 needs to be taken and placed, the first telescopic layer 230 can be used to move the yarn reel 10 to the first retractable layer 230. The first telescopic layer 230 and the second telescopic layer 240 move and extend, so that the yarn taking tray 210 moves toward the yarn reel 10, and after the yarn reel 10 is taken and placed, the first telescopic layer 230 and the second telescopic layer 240 can move in the opposite direction and retract, and the first telescopic layer 230 and the second telescopic layer 240 are arranged in a stacked manner, which not only realizes the yarn taking tray 210 to take and place the yarn reel 10 through the movement of the telescopic structure, but also the stacked arrangement of the first telescopic layer 230 and the second telescopic layer 240 has a more compact structure, and the cantilever structure of the first telescopic layer 230 and the second telescopic layer 240 reduces space occupancy and is more suitable for compact production workshops. In a specific embodiment, the first telescopic layer 230 and the second telescopic layer 240 are both linear track components.

[0047] Furthermore, the first telescopic layer 230 is driven to move by the first driving device, and the second telescopic layer 240 is driven to move by the second driving device, so that the first telescopic layer 230 and the second telescopic layer 240 can move independently of each other. Therefore, during the yarn taking process, when the distance from the wire drawing machine 20 is far, the first drive device and the second drive device simultaneously drive the first telescopic layer 230 and the second telescopic layer 240 to move, so as to ensure that the yarn taking tray 210 can be moved far enough to the wire drawing machine 20 to take out the yarn reel 10 in the wire drawing machine 20. When placing the yarn reel 10 on the yarn tile 31 of the yarn car 30, the yarn car 30 is close to the yarn taking tray 210. At this time, only the second drive device can drive the second telescopic layer 240 to move, so as to meet the requirement of the yarn taking tray 210 moving to the yarn car 30 to place the yarn reel 10 on the yarn tile 31 without the need for the first telescopic layer 230 to stretch, thus avoiding the first telescopic layer 230 and the second telescopic layer 240 extending for a long time at the same time to interfere with other equipment components. By moving independently of each other, the adaptability of the extension length of the telescopic mechanism is improved, and the occurrence of interference with surrounding equipment during the taking and placing process is prevented.

[0048] like Figure 5 and Figure 6As shown, the pick-up and placement part 200 also includes a tray bracket 220 and a sensor 260. The yarn picking tray 210 includes a yarn picking tile 211 and an elastic element 212. The yarn picking tile 211 is connected to the telescopic mechanism through the tray bracket 220. The yarn picking tile 211 is hingedly mounted on the tray bracket 220 so that the yarn picking tile 211 can rotate on the tray bracket 220. The sensor 260 is also mounted on the tray bracket 220, and the sensor 260 is located below the yarn picking tile 211. A trigger gap is set between the yarn picking tile 211 and the sensor 260, so that when the yarn picking tile 211 is in the state of rotation, the sensor 260 can rotate on the tray bracket 220. When carrying the yarn reel 10, the yarn taking tile 211 rotates under the action of the gravity of the yarn reel 10, and the yarn taking tile 211 is pressed onto the sensor 260. At this time, after the sensor 260 is triggered, it transmits a signal that the yarn taking tray 210 carries the yarn reel 10, so that the telescopic mechanism contracts to retract the yarn taking tray 210 carrying the yarn reel 10. After the yarn reel 10 on the yarn taking tray 210 is unloaded, the elastic element 212 restores the yarn taking tile 211 to its original state, and the yarn taking tile 211 and the sensor 260 are separated by a triggered gap. At this time, the yarn taking tray 210 is in an unloaded state. In a specific embodiment, the yarn taking tile 211 is provided with a trigger baffle 250 facing the sensor 260, and one end of the trigger baffle 250 has a bent section, which is bent toward the sensor 260 and extends downward. When the yarn taking tray 210 is in an unloaded state, the bent section of the trigger baffle 250 is spaced from the sensor 260 to form a trigger gap. After the yarn taking tray 210 carries the yarn reel 10, the yarn taking tile 211 rotates, and the bent section of the trigger baffle 250 abuts against the sensor 260, and the light of the sensor 260 is turned on, thereby sending a signal that the yarn reel 10 is carried. In addition, the yarn taking tile 211 is rotatably mounted on the tray bracket 220 through a rotating shaft, and the elastic element 212 is a torsion spring sleeved on the rotating shaft, which realizes the rotation of the yarn taking tile 211 and the recovery after unloading.

[0049] like Figure 4As shown, the pick-up and placement section 200 provided in this embodiment is provided with a plurality of yarn picking tile groups 211, each yarn picking tile group 211 includes two yarn picking tiles 211 to be arranged, and the yarn reel 10 is carried simultaneously by the two yarn picking tiles 211, and a sensor 260 is arranged correspondingly at the bottom of each yarn picking tile 211, and the plurality of yarn picking tile groups 211 are arranged in sequence and spaced apart along the extension direction of the tray bracket 220. Therefore, in the process of taking yarn, a plurality of yarn reels 10 can be carried simultaneously by the plurality of yarn picking tile groups 211, and one yarn reel 10 is placed on one yarn picking tile group 211, thereby improving the efficiency of the pick-up and placement section 200 in taking the yarn reel 10. In a specific embodiment, the placing and taking part 200 is provided with three yarn taking tile groups 211, and three yarn reels 10 can be taken out at the same time. When the placing and taking part 200 takes out three yarn reels 10 at the same time, the three yarn reels 10 are weighed one by one in sequence. After the first yarn reel 10 is weighed by the weighing part 300, the first yarn reel 10 is put back on the corresponding yarn taking tile group 211, and according to the weight of the first yarn reel 10, the placing and taking part 200 moves to the corresponding yarn reel 10 through the track part 100. The yarn cart 30 with the corresponding weight, then the first yarn drum 10 on the yarn tile 211 group is inserted into the yarn tile 31 through the telescopic mechanism, and then the second yarn drum 10 is inserted into the weighing rod 310 through the telescopic mechanism for weighing. After the measurement, according to the weighing result, the pick-up and placement part 200 moves and adjusts the position through the track part 100, and then the second yarn drum 10 is inserted into the yarn tile 31 of the yarn cart 30 with the corresponding weight through the telescopic mechanism, and the weighing, grouping and placement of the remaining yarn drums 10 are completed in this cycle. Of course, it can be understood that the pick-up and placement part 200 can also take one yarn drum 10 at a time to complete the weighing, grouping and placement. Those skilled in the art can design it according to actual needs, and this article will not go into details.

[0050] like Figure 4 and Figure 5 As shown, the two correspondingly arranged yarn taking tiles 211 in the yarn taking tile 211 group are both tilted, that is, the two tilted yarn taking tiles 211 are symmetrically arranged to form an obtuse angle, so that a positioning angle is formed between the two corresponding yarn taking tiles 211, and the yarn reel 10 is placed in the positioning angle formed by the two yarn taking tiles 211. The positioning angle formed not only improves the stability of the placement of the yarn reel 10, but also prevents the yarn reel 10 from shaking or even falling during the movement. In addition, the positioning angle formed by the two correspondingly arranged yarn taking tiles 211 also makes the axes of each yarn reel 10 placed on each yarn taking tile 211 group at the same time on the same axis. Therefore, during the weighing process, it is convenient to sequentially insert each yarn reel 10 into the weighing rod 310 for weighing and grouping one by one, and then place it on the yarn tile 31 of the corresponding yarn car 30.

[0051] like Figure 7As shown, the weighing part 300 includes a weighing tile 320, and the weighing tile 320 is arranged at the end of the weighing rod 310. After the weighing rod 310 penetrates into the yarn drum 10, the weighing rod 310 is attached to the inner wall of the yarn drum 10 through the weighing tile 320, and the weighing sensor is arranged below the weighing tile 320, between the weighing tile 320 and the weighing rod 310, which not only enables the weighing part 300 to weigh the yarn drum 10, but also protects the weighing sensor through the weighing tile 320.

[0052] In addition, the weighing tile 320 is configured as an arc structure. When the weighing tile 320 is installed on the weighing rod 310, the center of the arc structure is located on one side of the weighing rod 310, and during the weighing process of the yarn reel 10, the outer arc surface of the arc structure fits with the inner wall of the yarn reel 10. The weighing tile 320 designed with an arc structure has a higher contact area with the arc surface of the inner wall of the yarn reel 10 after the yarn reel 10 is put on the weighing tile 320, thereby improving the stability of the yarn reel 10 put on the weighing tile 320, and avoiding violent shaking of the yarn reel 10 during the weighing process of being lifted by the lifting mechanism, which is beneficial to improving the accuracy of the weighing result.

[0053] like Figure 7 As shown, the lifting mechanism provided in this embodiment includes a driving motor 330, a slide rail assembly 340 and a ball screw 350. The guide rail of the slide rail assembly 340 is also installed on the base, and the guide rail extends along the extension direction of the third track 130. The weighing rod 310 is connected to the slider in the slide rail assembly 340. At the same time, the driving motor 330 is connected to the weighing rod 310 through the ball screw 350. Therefore, after the yarn reel 10 on the yarn taking tile 211 is inserted into the weighing rod 310 through the telescopic mechanism, the driving motor 330 The ball screw 350 is driven to rotate, and then the weighing rod 310 connected to the ball screw 350 moves upward along the extension direction of the track in the slide rail assembly 340, lifting the yarn reel 10 from the yarn taking tile 211, and weighing the yarn reel 10 through the weighing sensor. After the weighing is completed, the driving motor 330 drives the ball screw 350 to rotate again, so that the weighing rod 310 moves downward along the track, and the yarn reel 10 is placed back on the yarn taking tile 211, thereby completing the weighing of the yarn reel 10.

[0054] The embodiment of the present invention also discloses a yarn unloading system, including a control system, a yarn car 30 and an automatic yarn unloading device. The information collected by each sensor and the positioning vision part of the automatic yarn unloading device is fed back to the control system. The control system controls the operation of the corresponding components of the automatic yarn unloading device according to the feedback information. In a specific embodiment, 12 yarn tiles 31 for placing the yarn reels 10 are arranged on both sides of the yarn car 30. Since the yarn unloading system has the above-mentioned automatic yarn unloading device, it has all the technical effects of the above-mentioned automatic yarn unloading device, which will not be repeated in this article.

[0055] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0056] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
