[0021] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0022] This utility model embodiment includes a support beam, a movable beam, a bidirectional telescopic loading and unloading platform 7, a tubular sliding contact line 11, a yarn rack car sensor 12, and a controller 13.

[0023] The support beam includes a support crossbeam 1 and a support longitudinal beam 2. Multiple support crossbeams 1 are distributed along the length of the support longitudinal beam 2, and all of them are fixedly connected to the support longitudinal beam 2.

[0024] The movable beam is mounted on the supporting beam and includes a movable crossbeam 3 and a movable longitudinal beam 4. The movable crossbeam 3 is slidably mounted on a movable slide rail on the supporting longitudinal beam 2 via a slider. A movable crossbeam drive mechanism 2-1 is mounted on the movable crossbeam 3, which drives the movable crossbeam 3 to move longitudinally along the movable slide rail on the supporting longitudinal beam 2. The movable crossbeam drive mechanism 2-1 uses a motor-driven gear and rack transmission; the motor and gear are mounted on the movable crossbeam 3, and the rack is mounted on the supporting longitudinal beam 2. The movable longitudinal beam 4 is slidably mounted on the movable crossbeam 3 via a movable slide table. A movable longitudinal beam drive mechanism 3-1 is also mounted on the movable crossbeam 3, connected to the movable longitudinal beam 4, driving the movable slide table and the movable longitudinal beam 4 to move laterally along the movable slide rail of the movable crossbeam 3. The movable longitudinal beam drive mechanism 3-1 uses a motor-driven lead screw and nut helical transmission; the motor and lead screw are mounted on the movable crossbeam 3, and the nut is mounted on the movable slide table.

[0025] A lifting drive mechanism 4-1 is installed on the movable longitudinal beam 4. The bidirectional telescopic loading and unloading platform 7 is lifted and mounted on the movable longitudinal beam 4 via a sliding rail. The bidirectional telescopic loading and unloading platform 7 is connected to the lifting drive mechanism 4-1, which drives the bidirectional telescopic loading and unloading platform 7 to move linearly along the movable longitudinal beam 4 in the height direction. The lifting drive mechanism 4-1 also uses a motor-driven screw-nut helical transmission method. The motor and screw are mounted on the movable longitudinal beam 4, and the nut is mounted on the bidirectional telescopic loading and unloading platform 7.

[0026] The bidirectional telescopic loading and unloading platform 7 includes a bidirectional telescopic mechanism, a yarn loading and unloading platform 74, a support frame 77, and a positioning sensor 78; the bidirectional telescopic mechanism includes a first telescopic platform 71, a second telescopic platform 72, a third telescopic platform 73, a telescopic drive motor 75, and a telescopic transmission mechanism 76.

[0027] The support frame 77 is mounted on the movable longitudinal beam 4 via a movable slide rail, and the support frame 77 is connected to the lifting drive mechanism 4-1. The first telescopic platform 71 is mounted on the support frame 77, the second telescopic platform 72 is mounted on the first telescopic platform 71, and the third telescopic platform 73 is mounted on the second telescopic platform 72. The telescopic transmission mechanism 76 is connected to the first telescopic platform 71, the second telescopic platform 72, and the third telescopic platform 73. The telescopic drive motor 75 is connected to the telescopic transmission mechanism 76, which pulls the first telescopic platform 71, the second telescopic platform 72, and the third telescopic platform 73 to complete bidirectional automatic telescopic movement, and simultaneously drives the yarn loading and unloading platform 74 to achieve bidirectional movement.

[0028] The yarn loading and unloading platform 74 includes a bracket 741, a weighing sensor 742, a slide table 743, a slide rail 744, a mounting plate 745, and a cylinder 746.

[0029] The two yarn loading and unloading platforms 74 are fixedly installed on the third telescopic platform 73 via mounting plates 745.

[0030] The weighing sensor 742 is installed at the bottom of the bracket 741 and can detect the weight of the yarn ball on the bracket in real time and send the weight information to the controller 13.

[0031] The bracket 741 is mounted on the slide table 743 via a load cell 742; the slide table 743 is slidably mounted on the mounting plate 745 via a slide rail 744; a cylinder 746 is mounted on the mounting plate 745 and connected to the slide table 743; the slide table 743 moves linearly along the slide rail 744 under the drive of the cylinder 746. The bracket 741 is V-shaped.

[0032] There are two yarn loading and unloading platforms 74, which can load and unload two yarn spools at the same time.

[0033] The positioning sensor 78 is installed on the third telescopic platform 73 to obtain high-precision position information of the drawing machine head 6 and the yarn ball support 10 and feed it back to the controller 13.

[0034] A tubular sliding contact line 11 is provided on the supporting crossbeam 1. The tubular sliding contact line 11 is connected to the moving crossbeam drive mechanism 2-1, the moving longitudinal beam drive mechanism 3-1 and the lifting drive mechanism 4-1, and is used to provide drive power to the moving crossbeam drive mechanism 2-1, the moving longitudinal beam drive mechanism 3-1 and the lifting drive mechanism 4-1.

[0035] A yarn frame sensor 12 is installed on the support beam 1, which can detect the position of the yarn frame 8 in real time and send the position signal to the controller 13.

[0036] The yarn rack 8 is equipped with multiple yarn ball supports 10, and each yarn ball support 10 can hold two yarn balls at the same time.

[0037] Another aspect of this utility model provides an automated loading and unloading method for glass fiber yarn bundles, comprising: (1) When two raw yarn balls 9 are formed on one of the multiple drawing machines 5, the machine automatically sends a signal to the controller 13 to be unloaded.

[0038] (2) After receiving the unloading signal of the wire drawing machine 5, the controller 13 controls the movement of the moving crossbeam drive mechanism 2-1, the moving longitudinal beam drive mechanism 3-1, and the lifting drive mechanism 4-1 according to the preset position information of the wire drawing machine 5 and the position information of the wire drawing machine head 6, so as to move the bidirectional telescopic loading and unloading platform 7 to the front end of the wire drawing machine head.

[0039] (3) When the bidirectional telescopic loading and unloading platform 7 is positioned to reach the front end of the drawing machine head, the controller 13 controls the telescopic drive motor 75 to rotate in the forward direction, driving the yarn ball loading and unloading platform 74 to extend to the underside of the original yarn ball 9 and maintain a certain distance from the original yarn ball 9.

[0040] (4) At this time, according to the actual position of the original yarn ball 9, the control cylinder 746 moves the bracket 741 to directly below the yarn ball.

[0041] (5) Once the bracket 741 is positioned, the controller 13 controls the bidirectional telescopic loading and unloading platform 7 to rise slowly, and the bracket 741 contacts the raw yarn bundle 9 until it is separated from the drawing machine head 6.

[0042] (6) During the process of the bracket 741 lifting the raw yarn bundle 9, the weighing sensor 742 detects the weight of the raw yarn bundle 9 in real time. When the weight of the two raw yarn bundles 9 is close to the set standard value of the raw yarn bundle and the weight value no longer changes, the bidirectional telescopic loading and unloading platform 7 stops rising, the telescopic drive motor 75 rotates in the opposite direction, driving the yarn bundle loading and unloading platform 74 and the raw yarn bundle 9 to retract, completing the unloading action of the two raw yarn bundles 9.

[0043] (7) After unloading, the controller 13 controls the movement of the moving crossbeam drive mechanism 2-1, the moving longitudinal beam drive mechanism 3-1, and the lifting drive mechanism 4-1 according to the position information of the yarn frame 8 and the yarn ball support 10, so as to move the bidirectional telescopic loading and unloading platform 7 to the front end of the yarn ball support 10, and prepare to put the raw yarn ball 9 onto the yarn frame 8.

[0044] (8) When the position of the raw yarn ball 9 moves to the position corresponding to the position of the yarn ball support 10, the controller 13 controls the telescopic drive motor 75 to rotate in the opposite direction, driving the yarn ball loading and unloading platform 74 to extend outward until the paper tube of the raw yarn ball 9 is inserted into the yarn ball support 10.

[0045] (9) After the paper tube of the raw yarn ball 9 is inserted into the yarn ball support 10, the bidirectional telescopic loading and unloading platform 7 slowly descends until the two weighing sensors 742 receive feedback that the weight is zero, and the two raw yarn balls 9 are removed from the support 741.

[0046] (10) After the raw yarn ball 9 is separated from the bracket 741, the telescopic drive motor 75 rotates in the forward direction, driving the yarn ball loading and unloading table 74 to retract, completing a fully automatic double pick-up and double release of the raw yarn ball.

[0047] (11) During the process of unloading the raw yarn ball 9 from the drawing machine head 6 to the bracket 741, or loading it from the bracket 741 to the yarn ball support 10, if the difference in the values ​​fed by the weight sensor 742 on the two yarn ball loading and unloading platforms 74 exceeds a certain value, the controller 13 will first stop the unloading or loading action, then judge the position information of the two yarn balls again, and adjust the position of the yarn ball loading and unloading platform 74 and the two brackets in real time, which can avoid the failure of picking up and placing yarn balls due to actual position deviation or sensor detection accuracy.

[0048] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the construction, features, and principles of this utility model are included within the protection scope of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined by the claims, all of which should fall within the protection scope of this utility model.
