The bag storage sorting mechanism 9 is equipped with a protective shell. The bag storage sorting mechanism 9 specifically includes a bag storage clamping arm 901, a bag storage clamping drive 902, and a bag storage micro-loosening drive 903. The bag storage clamping drive 902 is mainly used to drive the bag storage clamping arm 901 to clamp the woven bags in the bag storage. The bag storage micro-loosening drive 903 is used to slightly loosen the clamped woven bags to ensure that the gantry gripper mechanism 6 can smoothly pull the woven bags out of the bag storage.

Its gear meshes with the rack and is fixed to the output shaft of the horizontal bag-pulling drive motor, which is mounted on the side of the lifting bag-pulling mounting base 606 away from the lifting bag-pulling assembly. In this horizontal bag-pulling assembly, since the rack of the horizontal bag-pulling drive 602 is fixed, during operation, the horizontal bag-pulling drive motor drives the gear to rotate and synchronously move along the rack, generating linear displacement. This, in turn, drives the lifting bag-pulling assembly to move horizontally along the horizontal bag-pulling guide rail 601 via the lifting bag-pulling mounting base 606.

[0040] Specifically, in the aforementioned lifting bag-drawing assembly, the rack of the lifting bag-drawing drive component 605 is fixed to one side of the lifting bag-drawing guide rail 604. Its gear meshes with the rack and is fixed to the output shaft of the lifting bag-drawing drive motor. The lifting bag-drawing drive motor is mounted on the side of the lifting bag-drawing mounting base 606 near the lifting bag-drawing assembly. In this lifting bag-drawing assembly, the rack of the lifting bag-drawing drive component 605 is not fixed. During operation, the lifting bag-drawing drive motor drives the gear to rotate, the rack to move linearly, and synchronously drives the lifting bag-drawing guide rail 604 to move up and down, thereby driving the gantry gripper assembly to move up and down.

[0041] In addition, the aforementioned left-right driving component 612 and front-back driving component 616 can be adopted as a gear and rack moving mechanism or a cylinder, hydraulic cylinder, etc. Specifically, in this embodiment, the aforementioned left-right driving component 612 is a common cylinder, and two left-right driving components 612 are provided, respectively symmetrically arranged below the gantry gripper mounting beam 607, and one end of the cylinder seat of each left-right driving component 612 is hinged to the bottom of the gantry gripper mounting beam 607, and one end of the piston rod of each left-right driving component 612 is connected to the corresponding left gantry gripper mounting plate 613 and right gantry gripper mounting plate 614 respectively; during operation, when the two left-right driving components 612 move synchronously, they can drive the left gantry gripper 608 and the right gantry gripper 609 to move towards or away from each other along the left-right clamping guide rail 611. Specifically, in this embodiment, the aforementioned forward and backward driving member 616 is a split slide cylinder, and each forward and backward driving member 616 is connected to the two arc-shaped gantry gripper arms 610 of the gantry gripper on the same side. When the two forward and backward driving members 616 move synchronously, they can drive the two arc-shaped gantry gripper arms 610 of the left gantry gripper 608 and the right gantry gripper 609 to move towards or away from each other.

[0042] In addition, in this embodiment, the gantry gripper assembly further includes a detection switch 617, and the bottom end of the detection switch 617 is provided with a detection surface. The detection switch 617 is located between the left gantry gripper 608 and the right gantry gripper 609, and the detection surface of the detection switch 617 is flush with the upper inner arc surface of the arc-shaped gantry gripper arm 610. The detection switch 617 is used to control the lifting bag-pulling assembly to stop descending when the detection surface of the detection switch 617 touches the woven bag during the process of the lifting bag-pulling assembly driving the gantry gripper assembly to descend.

[0043] The aforementioned horizontal bag-pulling drive 602, lifting bag-pulling drive 605, left-right direction drive 612, front-back direction drive 616, and detection switch 617 are all connected to the PLC control system, which enables the automatic extraction of woven bags.

[0044] Based on the aforementioned controllable yarn extraction device for woven bags, the yarn in woven bags with one end open is automatically extracted. The specific steps are as follows: (1) The woven bag containing the yarn tubes enters the woven bag hopper through the woven bag conveyor line 1, and the bag opening of the woven bag is located at the end of the woven bag hopper 1 near the hopper limiting mechanism 3. After the woven bag reaches the set position, the hopper limiting mechanism 3 blocks the woven bag. (2) The bag storage sorting mechanism 9 sorts the woven bags. The bag storage clamping drive 902 and the synchronous motion component 10 drive the bag storage clamping arm 901 and the bag storage clamping plate 904 to move towards each other to clamp the woven bags. At the same time, the woven bags are located in the middle area of ​​the woven bag storage and the yarn in the woven bags are arranged neatly. Then the bag storage slightly loosening drive 903 moves in the opposite direction, driving the bag storage clamping arm 901 and the bag storage clamping plate 904 to move away from each other, so that the clamped woven bags are slightly loosened. (3) The flipping drive cylinder 5 flips the woven bag conveyor line 1 from the horizontal direction to the vertical direction, and the input end of the woven bag bin faces upward; (4) The gantry gripper mechanism 6 grabs the edge and corner of the woven bag from the input end of the woven bag bin and pulls out the woven bag. The yarn inside the woven bag remains in the woven bag bin. Then the flip drive cylinder 5 flips the woven bag conveyor line 1 from the vertical direction to the horizontal direction. After the woven bag conveyor line 1 is reset to the horizontal direction, the yarn is arranged vertically and neatly above the woven bag conveyor line 1, thus completing the removal of the yarn from the woven bag.

[0045] The specific process of the gantry gripper mechanism 6 grabbing and pulling out the woven bag in step (4) above is as follows: the horizontal bag pulling drive 602 drives the lifting bag pulling assembly and the gantry gripper assembly to move above the woven bag compartment. At the same time, the left and right drive 612 drives the left gantry gripper 608 and the right gantry gripper 609 to move in opposite directions, and the front and back drive 616 drives the two arc-shaped gantry gripper arms 610 of each group of gantry grippers to move in opposite directions, so that the left gantry gripper 608 and the right gantry gripper 609 are both in the open state; then the lifting bag pulling drive 605 moves and drives The gantry gripper assembly moves downwards. When the detection surface of the detection switch 617 touches the woven bag, the lifting and pulling bag drive 605 stops moving. Then, the left and right drive 612 drives the left gantry gripper 608 and the right gantry gripper 609 to move towards each other, clamping the top edge of the woven bag on both sides. The front and back drive 616 drives the two arc-shaped gantry gripper arms 610 of each gantry gripper to move towards each other, clamping the top edge of the woven bag on both the front and back sides. Finally, the lifting and pulling bag drive 605 moves and drives the gantry gripper assembly to move upwards, simultaneously pulling the woven bag out.

[0046] In addition, since the woven bag compartment is in a vertical state, in order to avoid excessive lifting stroke of the lifting bag extraction assembly, when extracting the woven bag in step (4) above, the lifting bag extraction assembly can be used to extract part of the woven bag upwards first, and then the horizontal bag extraction drive 602 can be used to drive the lifting bag extraction assembly and the gantry gripper assembly to move away from the woven bag compartment (specifically, it can move towards the input end of the woven bag conveyor line) to extract the remaining woven bag.

[0047] Example 2 This embodiment provides a controllable removal device for woven bag yarn, which differs from Embodiment 1 in that: in this embodiment, only one set of bag compartment limiting mechanism 3 is provided. The bag compartment limiting mechanism 3 is slidably mounted on the bag compartment limiting mounting frame 11 along the conveying direction of the woven bag conveying line 1, and the bag compartment limiting mounting frame 11 is provided with a bag compartment limiting adjustment drive mechanism (not shown in the figure) that can drive the bag compartment limiting mechanism 3 to slide. The bag compartment limiting adjustment drive mechanism can specifically adopt a cylinder, hydraulic rod or screw transmission mechanism, etc. The blocking and limiting position of the bag compartment limiting mechanism 3 can be adjusted by the bag compartment limiting adjustment drive mechanism to match woven bags of different lengths.

[0048] Example 3 Reference Figure 8This embodiment provides a controllable yarn extraction device for woven bags. The difference between this embodiment and Embodiment 1 is that a yarn conveying line 12 is provided close to the side of the output end of the woven bag conveying line 1. The yarn conveying line 12 is arranged above the second frame 13. The conveying direction of the yarn conveying line 12 is perpendicular to the conveying direction of the woven bag conveying line 1. The height of the yarn conveying line 12 is slightly lower than that of the woven bag conveying line 1 (specifically, it can be set to be 5~10mm lower than the woven bag conveying line). The width of the yarn conveying line 12 is slightly wider than the height of a single yarn package (specifically, it can be set to be 2~10mm wider than the height of a single yarn package). In addition, an anti-drop plate 1201 is provided on the side of the yarn package conveyor line 12 away from the woven bag conveyor line 1. The anti-drop plate 1201 is used to prevent the yarn package from falling off the yarn package conveyor line 12 when it falls from the woven bag conveyor line 1 onto the yarn package conveyor line 12. The output end of the yarn package conveyor line 12 is provided with a yarn package baffle 1202 and a corresponding photoelectric detector. The yarn package baffle 1202 is hinged above the output end of the yarn package conveyor line 12 via a bracket. The yarn package baffle 1202 is used to ensure that the yarn packages are output one by one when the yarn package conveyor line 12 conveys the yarn packages. That is, when the yarn package conveyor line 12 conveys the yarn packages to its output end and the photoelectric detector detects that a yarn package has been output, the yarn package conveyor line 12 stops and the yarn package baffle 1202 blocks the next yarn package.

[0049] After the woven bag is pulled out and the woven bag conveyor line 1 is reset to the horizontal direction, the yarn packages are neatly arranged in a vertical position above the woven bag conveyor line 1. At this time, the bag compartment limiting mechanism 3 can be reset to release the obstruction limit and the yarn packages on the woven bag conveyor line 1 can be conveyed to the subsequent process. Specifically, the woven bag conveyor line 1 conveys a row of yarn packages close to the yarn package conveyor line 12 to its output end. The yarn packages tilt and fall above the yarn package conveyor line 12 due to their own inertia and gravity. At this time, the yarn packages are horizontal (their axis is perpendicular to the conveying direction of the yarn package conveyor line 12). Then the yarn package conveyor line 12 conveys the yarn packages one by one to the subsequent process. After the yarn package conveyor line 12 has finished outputting the first row of yarn packages, the woven bag conveyor line 1 conveys another row of yarn packages close to the yarn package conveyor line 12 to the yarn package conveyor line 12. The above process is repeated until all yarn packages are conveyed.

[0050] Example 4 Reference Figure 9 This embodiment provides a controllable removal device for woven bag yarn. The difference between this embodiment and embodiment 3 is that this embodiment also includes an empty woven bag storage rack 14 and an empty woven bag storage box 15 located on at least one side of the empty woven bag storage rack 14. The empty woven bag storage rack 14 and the empty woven bag storage box 15 are located on the conveyor line in front of the input end of the woven bag conveyor line 1.

[0051] In this embodiment, after the woven bag is pulled out, the horizontal bag pulling drive 602 drives the lifting bag pulling assembly and the gantry gripper assembly to grab the empty woven bag and move it to the input end of the woven bag conveyor line 1. When it moves to the top of the empty woven bag temporary storage rack 14, the gantry gripper assembly releases and places the empty woven bag on the empty woven bag temporary storage rack 14. The empty woven bag is then manually transferred to the empty woven bag temporary storage box 15 for temporary storage.
