Abstract
Description
Technical Field
[0001] This invention relates to a packing equipment for chemical fiber filament cakes in the textile field, specifically to a multifunctional robot gripper and its working method for packing filament cakes. Background Technology
[0002] To ensure the appearance quality of the synthetic fiber cakes is not compromised, they must be free from defects such as dents, fuzz, lint, and contamination during the packing process. Therefore, the packing procedure is quite complex. After the carton is lined with a thin film bag, a bottom cardboard layer is placed first; then a layer of cake positioning plates is added before placing another cake, and so on, repeating this process for n layers. Finally, a top cardboard layer is added, and the film bag is closed and the carton is sealed. Due to the numerous steps, current cake packing is primarily done manually, or with multiple robots used for loading cakes, placing cardboard, and using positioning plates. Even with robots, the robot grippers can only accommodate cakes of the same size and a specific packing spacing. If the cake size or packing spacing changes, multiple robot grippers need to be designed and manufactured to match. Changing the cake size or packing spacing necessitates changing the robot grippers, resulting in high labor intensity, high costs, and low efficiency for workers on such production lines. Therefore, in order to improve the packing efficiency of chemical fiber filament cakes and the compatibility of the production line, it is necessary to develop a multi-functional robot gripper that can not only grab and stack filament cakes, but also grab and stack cardboard and filament cake positioning plates, and be compatible with filament cakes of different sizes and their packing arrangement spacing.

[0065] The following examples further illustrate specific embodiments of the present invention, but the present invention is not limited to these examples.
[0066] Example 1:
[0067] To address the shortcomings of the existing technology, the present invention aims to provide a multifunctional robot gripper and its working method for packing silk cakes, such as... Figure 1 As shown, it can not only grab and stack silk cakes, but also grab and stack cardboard 65 and silk cake positioning plate 64.
[0068] like Figure 1As shown, the present invention provides a multifunctional robot gripper 66 for packing shredded cakes, which mainly includes a support frame 1, a lateral movement mechanism 2, a longitudinal movement mechanism 3, a gripping mechanism 4, and a suction mechanism 5. The support frame 1 is installed at the end of the robot; the longitudinal moving mechanism 3 is installed on the mounting bracket 13 of the support frame 1 via the first linear guide rail; the transverse moving mechanism 2 is installed on the support plate 38 of the longitudinal moving mechanism 3 via the second linear guide rail; 12 sets of gripping mechanisms 4 are respectively installed on the mounting base 24 of the transverse moving mechanism 2, and the gripping mechanism 4 and the mounting base 24 are in a one-to-one correspondence. Their number and arrangement are consistent with the number and arrangement of each layer of silk cake 6 during packing. In this case, there are 12 silk cakes per layer, arranged in 3 rows and 4 columns; 4 sets of suction mechanisms 5 are symmetrically fixed on the pneumatic gripper connecting base 41 of the gripping mechanism 4. In this case, there are 4 sets of suction mechanisms 5, symmetrically installed on the gripping mechanisms 4 at the 4 corners; the robot clamp of the present invention is installed at the end of the robot via the support frame 1. The robot drives the entire robot clamp to move between the silk cake packing production line. The robot drives the robot clamp to move up and down for gripping and stacking silk cakes and gripping and stacking cardboard 65 and silk cake positioning plate 64.
[0069] like Figure 2 As shown, the support frame 1 includes a robot connecting plate 11, connecting columns 12, and a mounting frame 13. The robot connecting plate 11 is connected to the robot end effector and is used to mount the servo slide 21 of the lateral movement mechanism 2. The main body of the mounting frame 13 is welded from rectangular tubing into a rectangular frame with a longitudinal beam in the middle. The upper surface is welded with positioning and connecting parts for the longitudinal movement mechanism 3, which is used to mount the longitudinal movement mechanism 3. Four connecting columns 12 connect the robot connecting plate 11 and the mounting frame 13 into a whole, and the space between the robot connecting plate 11 and the mounting frame 13 is used to mount the longitudinal movement mechanism 3 and the lateral movement mechanism 2.
[0070] like Figure 3As shown, the lateral movement mechanism 2 includes a servo slide 21, a push plate 22, a linkage mechanism 23, a mounting base 24, a linkage fixing shaft 25, a second guide rail slider assembly 26, and a guide groove 27. The lateral moving mechanism 2 is fixed to the support plate 38 of the longitudinal moving mechanism 3 by multiple sets of second linear guide rails; the servo slide 21 is fixed to the robot connecting plate 11; the push plate 22 is connected to the servo slide 21, and the servo slide 21 drives the ends of multiple sets of linkage mechanisms 23 to extend and retract horizontally through the push plate 22; the two ends of the linkage mechanism 23 are two sets of short linkages, and multiple sets of long linkages are arranged in the middle, with the linkages hinged together; the hinge shaft in the middle of each linkage mechanism is the linkage fixing shaft 24, which is fixedly installed on the left and right rotating nuts 35 or the fixing seat 36 of the longitudinal moving mechanism 3; each set of mounting seats 24 is arranged at equal intervals, fixed to other hinge shafts of the linkage, and connected to the second slider, and can move with the second slider; one set of outer longitudinal mounting seats 24 is equipped with a guide groove 27, and the push plate 22 is in this set of guide grooves 27, and the guide groove 27 can move along the push plate 22. When the lateral moving mechanism 2 is started, with the connecting rod fixed shaft 25 in the middle of the connecting rod as the reference, each group of connecting rod mechanisms 23 extends and retracts horizontally, and drives the mounting seats 24 in the same group to change at equal intervals.
[0071] like Figure 4 As shown, the longitudinal moving mechanism 3 includes a servo motor reducer 31, a reducer mounting base 32, a coupling 33, left and right helical screws 34, left and right helical nuts 35, a fixed base 36, a bearing seat 37, a support plate 38, and a first guide rail slider assembly 39. The longitudinal moving mechanism 3 is fixed to the mounting bracket 13 of the support frame 1 via the first linear guide rail 39, the reducer mounting base 32, and the bearing seat 37; the coupling 33 connects the shaft of the servo motor reducer 31 and the left and right helical screws 34; the middle section of the left and right helical screws 34 is a smooth shaft, the left side adjacent to the smooth shaft is a left-hand helical screw section, and the right side is a right-hand helical screw section, and the pitch of the left and right helical screw sections is the same, only the direction of rotation is different. The two ends of the left and right helical screws are smooth shaft sections, one end is connected to the coupling 33, and the other end is connected to the bearing seat 37; the left and right helical nuts 35 include: Left-handed and right-handed nuts are respectively matched with left-handed and right-handed lead screws. The left-handed nuts are distributed on the left-handed lead screw section and fixed on the left-handed support plate 38, while the right-handed nuts are distributed on the right-handed lead screw section and fixed on the right-handed support plate 38, and the two are symmetrically distributed. There are multiple support plates 38. The middle support plate 38 is fixed on the mounting bracket 13, and the two side support plates 38 are connected to the first slider and can move with the first slider. The fixing seat 36 is installed in the center of the middle support plate 38. The fixing seat 36 has a smooth hole in the middle, through which the left-handed and right-handed lead screws 34 pass. When the longitudinal moving mechanism 2 is started, with the middle support plate 38 as the reference, the two side support plates 38 converge toward or move away from the middle support plate 38.
[0072] like Figure 5As shown, the gripping mechanism 4 includes a pneumatic gripper connecting seat 41, a pneumatic gripper 42, and a clamping jaw 43. The pneumatic gripper connecting seat 41 is mounted on the mounting seat 24 of the transverse moving mechanism 2 and can move with the mounting seat 24. The length of the pneumatic gripper connecting seat 41 is determined according to the packing depth. The pneumatic gripper 42 is the power source and is threadedly connected to the pneumatic gripper connecting seat 41. The clamping jaw 43 is used to grip the inner wall of the paper tube of the silk cake 6. It is threadedly connected to the pneumatic gripper 42. The pneumatic gripper 42 includes two movable fingers, and the clamping jaw 43 is fixedly connected to the two movable fingers. The pneumatic gripper 42 itself is the power source of the gripping mechanism. It controls the opening and closing of its own fingers through the air circuit, thereby driving the clamping jaw fixed to the pneumatic gripper fingers to open and close. The maximum diameter of the clamping jaw 43 is smaller than the inner wall of the paper tube of the silk cake. After extending into the inner wall of the paper tube, it grips the silk cake. The gripping device is mainly used to grip the entire layer of silk cakes each time during packing. Therefore, the number and arrangement of the gripping mechanism 4 are consistent with the number and arrangement of each layer of silk cakes 6 during packing.
[0073] like Figure 6 As shown, the suction mechanism 5 includes: a cylinder 51, a cylinder mounting base 52, an air connector 53, and a suction cup 54. The suction mechanism 5 is mainly used to suction the cardboard 65 and the silk cake positioning plate 64. Therefore, to ensure stable suction, multiple suction mechanisms 5 are arranged symmetrically. The suction mechanism 5 itself can move up and down via the cylinder 51, and the cylinder rod of the cylinder 51 is connected to the suction cup 54 via the air connector 53. When the gripping mechanism 4 is working, the cylinder rod of the cylinder 51 is in the retracted state, and the suction cup 54 is above the gripper 43, not affecting the silk cake packaging. When the suction mechanism 5 is working, the cylinder rod of the cylinder 51 is in the extended state, and the suction cup 54 is below the gripper 43, so the gripper 43 does not affect the silk cake packaging. The suction cup 54 picks up the cardboard 65 and the silk cake positioning plate 64. The suction cup is a vacuum suction cup, and the suction and release of the suction cup are controlled by controlling the inflation and deflation of the air. The cylinder mounting base 52 includes a ring with a diameter that matches the diameter of the rod-shaped structure of the gripper connecting seat 41. The cylinder mounting base 52 is fixedly connected to the rod-shaped structure of the gripper connecting seat 41 through the ring. The length of the cylinder 51 is less than that of the gripper connecting seat 41. The cylinder mounting base 52 is installed at the end of the gripper connecting seat 41 near the gripper 42. The length of the cylinder 51 on the cylinder mounting base 52 is less than that of the gripper connecting seat 41.
[0074] The present invention can achieve the following beneficial effects by adopting the above technical solution: the multifunctional robot gripper 66 for packing shredded cakes can not only grab and stack shredded cakes, but also grab and stack cardboard 65 and shredded cake positioning plate 64. Moreover, it can grab one layer of shredded cakes from the conveyor line at the same time each time. During the movement of the gripper, the lateral and longitudinal displacement between each shredded cake can be realized to adapt to the spacing of the shredded cake packing arrangement.
[0075] This gripper can perform various gripping and stacking tasks, greatly improving packing efficiency and reducing production costs. Both the lateral and longitudinal movement mechanisms of the gripper are servo-controlled, featuring a compact structure, precise displacement, and reliable operation. The gripper is compatible with different sizes of yarn cakes and their packing spacing, demonstrating strong versatility.
[0076] Example 2
[0077] like Figure 7 As shown, in this embodiment, the multifunctional robot gripper 66 of the present invention is mounted on the robot body via a robot connecting plate. The robot gripper moves between the silk cake positioning plate 64, the silk cake, the cardboard 65 and the empty carton 61 as the robot body moves.
[0078] Preliminary preparation stage: After the chemical fiber filament cakes are grouped, they are sequentially transported to the gripping station from the two middle filament cake conveyor lines at the front of the robot; 61 empty cardboard boxes are then placed in film bags and transported to the filament cake packing station 62 from the side conveyor lines of the robot; 65 cardboard boxes are transported to the suction station from the middle conveyor line at the rear of the robot; and 64 filament cake positioning plates are transported to the suction station from the two side conveyor lines at the rear of the robot.
[0079] A working method for a multi-functional robot gripper 66 used for packing silk cakes:
[0080] After preparation, the robot moves with its gripper above the cardboard 65. The robot extends downwards, activating the suction mechanism. Cylinder 51 starts working, extending its cylinder rod. Suction cup 54 is positioned below gripper 42, and the suction mechanism picks up the cardboard 65. To ensure stable suction, the suction mechanism is symmetrically positioned. The robot retracts and moves, placing the cardboard 65 into the empty cardboard box 61. The robot retracts again, then moves above the silk cake positioning plate 64. The lateral movement mechanism 2 and the longitudinal movement mechanism 3 adjust their spacing. The suction mechanism picks up the silk cake positioning plate 64 and places it into the empty cardboard box 61. The robot retracts again. The robot moves above the silk roll. Through adjustments to the lateral movement mechanism 2 and the longitudinal movement mechanism 3, the gripper 43 of the grasping mechanism 4 aligns with the inner wall of the paper tube containing the silk roll. Because it grasps the inner wall of the paper tube, there are few restrictions on the size of the silk roll. The spacing can also be adjusted using the lateral movement mechanism 2 and the longitudinal movement mechanism 3. After aligning with the inner wall of the paper tube, the gripper 43 clamps the inner wall, and the robot moves it back into the carton. Through adjustments to the lateral movement mechanism 2 and the longitudinal movement mechanism 3, it completes positioning with the silk roll positioning plate 64, places the silk roll down, and then repeats the action of picking up one layer of silk roll positioning plate 64 and picking up one layer of silk roll until the carton is full. Finally, another layer of cardboard 65 is picked up and placed into the carton. This completes one work cycle of the silk roll packing station 62.
[0081] Packing Stage: The multi-functional robot uses gripper 66 to first activate suction mechanism 5 to pick up a layer of cardboard 65 and place it at the bottom of the carton. Then, after adjusting the spacing of suction mechanism 5, it picks up a layer of silk cake positioning plate 64 and places it into the carton. Next, it activates gripping mechanism 4, adjusts the spacing of the 12 gripping mechanisms 4, and picks up 12 silk cakes 6 at a time from the silk cake conveyor line. It then adjusts the spacing to fit the silk cake positioning plate 64 and places a layer of 12 silk cakes onto the silk cake positioning plate 64 inside the carton. Then, it repeats the action of picking up a layer of silk cake positioning plate 64 and picking up a layer of silk cake 6 until the carton is full. Finally, it picks up another layer of cardboard 65 and places it into the carton. This completes one work cycle of silk cake packing station 62.
