Description

Technical Field

[0001] The invention relates to the technical field of yarn cake stacking, and in particular to a nylon yarn cake stacking device and method for processing nylon DTY low-elastic yarn. Background Art

[0002] Nylon DTY low-elastic yarn refers to a synthetic fiber made from polyamide particles as the main material and additives after melting, cooling, stretching and other processes. It has good strength, wear resistance and elasticity. Nylon DTY low-elastic yarn is usually wound into a yarn cake after processing. The stacking device is used to move the stacked nylon yarn cakes and stack them on shelves of different heights for packaging;

[0003] Existing stacking devices use a variety of methods to achieve the stacking of nylon yarn cakes, such as a nylon yarn cake stacking device with a publication number of CN112061799B, which includes an electric linear slide, a screw lifting mechanism for driving the electric linear slide to lift and lower, and a grabbing manipulator installed on the electric linear slide, and also includes a stacking positioning mechanism, and the stacking positioning mechanism is placed on the moving path of the electric linear slide;

[0004] Since the shape of nylon yarn cakes is usually round, and the multiple grabbing hands on the existing stacking device are usually fixed in position and on the same plane, when grabbing the nylon yarn cake, the grabbing hand in the middle can fit with the nylon yarn cake, while the grabbing hands on the side cannot fit with the nylon yarn cake well, and the grabbing stability is poor. At the same time, when stacking, the multiple nylon yarn cakes on the existing stacking device fit together, so that when unloading, it can only be unloaded in order from top to bottom, and it is impossible to unload nylon yarn cakes at different positions according to actual needs;

[0005] For example, in the prior art referred to above, the three clamping claws used in the device have the same height, so when the clamping claw in the middle is clamped and fitted with the nylon yarn cake, the clamping claws on both sides cannot completely clamp the nylon yarn cake, and the problem of loose grasping exists when grasping the nylon yarn cake placed horizontally or vertically. When unloading, the existing device cannot take out the nylon yarn cake at a specific position in the nylon yarn cake pile according to the demand, and can only unload from top to bottom, which has poor functionality and certain limitations;

[0024] S4. As the number of nylon yarn cakes on the stacking assembly increases, the stacking assembly will automatically adjust its height position according to the weight of the nylon yarn cakes on it, thereby realizing automatic stacking support and arrangement of multiple nylon yarn cakes;

[0025] S5, repeating steps S2-S4 until the number of nylon yarn cakes in the stacking unit reaches a maximum value, and the nylon yarn cake stacking is completed;

[0026] S6. Move the support base to move the stacking unit to the shelf for storing nylon yarn cakes, start the loading and unloading components and the lifting components, and place the multiple nylon yarn cakes in the stacking component in the corresponding positions on the shelf in turn to complete the automatic unloading and storage stacking of the nylon yarn cakes.

[0027] The present invention provides a nylon yarn cake stacking device and method for processing nylon DTY low-elastic yarn, which has the following beneficial effects:

[0028] 1. When stacking nylon yarn cakes, the stacking device of the present invention can flexibly adjust the height position of the loading and unloading components through the cooperation of the lifting components, so that it can cooperate with nylon yarn cakes of different heights in the nylon yarn cake pile, and can realize the stacking, grabbing and loading of nylon yarn cakes of different heights, and the loading range is wider.

[0030] 3. When stacking nylon yarn cakes, the stacking device of the present invention utilizes the cooperation of the two rotating side grabbing frames and the bending spring rod. When the middle grabbing frame fits with the nylon yarn cake, the thrust can drive the two side grabbing frames to automatically push forward and bend, so that the two side grabbing frames can also fit with the nylon yarn cake, which can effectively improve the grabbing stability of the feeding yarn cake.

[0031] 4.

DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example 1: Reference Figure 1-Figure 2 A nylon yarn cake stacking device for processing nylon DTY low-elastic yarn includes a support frame 5 arranged on a support base 1, and the support base 1 cooperates with the support frame 5 to stably support the internal structure of the stacking device and improve the stability of the stacking process;

[0051] A plurality of moving wheels are provided at the lower part of the supporting base 1, and the plurality of moving wheels are used to realize the overall movement of the stacking device, so as to facilitate the grabbing and loading of nylon yarn cake piles at different positions, and stack the nylon yarn cakes on different stable shelves.

[0052] The stacking device further includes: a stacking unit, which is arranged on the support frame 5 and is used to realize loading and unloading of nylon yarn cakes and automatic stacking. Nylon yarn cakes at different positions can be grabbed on the pile and the grabbed nylon yarn cakes can be temporarily stacked. Multiple nylon yarn cakes can also be separated according to the number and weight of the stacked nylon yarn cakes to prevent the nylon yarn cakes from piling up and sticking together. Therefore, when unloading, nylon yarn cakes at different positions can be unloaded according to needs, without the need to unload in order from top to bottom;

[0053] The lifting assembly is arranged on the support frame 5, and is used to adjust the height of the stacking unit, so as to load, stack and unload nylon yarn cakes of different heights, and can grab nylon yarn cakes of different heights, and stack the stacked nylon yarn cakes to different heights and positions on the shelf, which has a wider range of applications;

[0054] The control box 2 is arranged on the side of the support frame 5, and is used to control the opening and closing and operation status of the lifting assembly and the stacking unit, so as to realize the automatic stacking of multiple nylon yarn cakes.

[0055] Example 2: Reference Figure 2 , Figure 4-Figure 8 The technical solution of this embodiment is different from that of the first embodiment in that the stacking unit is composed of a loading and unloading assembly and a stacking assembly, wherein the loading and unloading assembly is used to realize automatic loading and unloading of nylon yarn cakes, and the stacking assembly is used to realize automatic arrangement and stacking of multiple nylon yarn cakes;

[0056] The loading and unloading assembly includes a stacking platform 9, and the stacking platform 9 is installed on the support frame 5 through a limiting mechanism, and two hydraulic rods 21 for adjusting the height are installed on the stacking platform 9 through a moving reciprocating mechanism;

[0057] The mobile reciprocating mechanism includes a servo motor 14 fixedly mounted on the stacking platform 9, a driving roller 15 fixedly mounted on the driving end of the servo motor 14, a driving gear 16 fixedly mounted on the driving roller 15, a moving cross bar 20 slidably mounted on the stacking platform 9, and two hydraulic rods 21 are both arranged on the moving cross bar 20, a driving gear rod 19 fixedly mounted on the lower part of the moving cross bar 20, and the driving gear rod 19 is meshed with the driving gear 16;

[0058] A moving trolley is provided at the lower part of the two hydraulic rods 21, and the moving trolley is used to enable the two hydraulic rods 21 to move horizontally on the moving cross bar 20, so that the distance between the hydraulic rods 21 can be adjusted, which is more conducive to grabbing nylon yarn cakes of different sizes;

[0059] When the servo motor 14 is started, it will drive the driving roller 15 to rotate forward and reversely. The rotation of the driving roller 15 will drive the driving gear 16 thereon to rotate forward and reverse, thereby driving the driving gear rod 19 meshing with the driving gear 16 to move back and forth. When the driving gear rod 19 is pushed forward, it will drive the moving cross bar 20 to move forward, and vice versa, which can drive the two hydraulic rods 21 on the moving cross bar 20 to move back and forth on the stacking frame 11.

[0060] In a further embodiment, a grabbing mechanism for positioning the nylon yarn cake is installed between the two hydraulic rods 21, and the grabbing mechanism includes a middle grabbing frame 22, and the driving ends of the two hydraulic rods 21 are rotatably mounted with side grabbing frames 13, and two sets of curved spring rods 23 are rotatably mounted on the middle grabbing frame 22, and the sides of the two sets of curved spring rods 23 away from the middle grabbing frame 22 are rotatably mounted on the two side grabbing frames 13 respectively;

[0061] When the nylon yarn cake is being loaded, the servo motor 14 is started to drive the two hydraulic rods 21 forward through the cooperation of the driving roller 15, the driving gear 16, the driving gear rod 19 and the moving cross bar 20, thereby driving the two side grabbing frames 13 forward. When the two side grabbing frames 13 are pushed forward, the middle grabbing frame 22 is driven forward through the two sets of curved spring rods 23;

[0062] When the middle grabbing frame 22 fits with the side of the nylon yarn cake, the two side grabbing frames 13 are pushed forward continuously. Since the middle grabbing frame 22 cannot move under the pressure of the nylon yarn cake, the two side grabbing frames 13 are deflected and bent under the elastic action of the two sets of curved spring rods 23 when they are pushed forward. The two side grabbing frames 13 are pushed forward continuously until the two side grabbing frames 13 fit and squeeze with the side of the nylon yarn cake, so that the two side grabbing frames 13 and the middle grabbing frame 22 form an arc state as a whole, and the nylon yarn cake can be grabbed. This grabbing and fitting method is not affected by the shape of the nylon yarn cake, that is, square, oval or round nylon yarn cakes can be effectively grabbed.

[0063] The central grabbing frame 22 and the two side grabbing frames 13 are both provided with vacuum suction cups 24 for adsorbing and positioning the nylon yarn cake. When the central grabbing frame 22 and the two side grabbing frames 13 are pressed and fitted with the sides of the nylon yarn cake, the multiple vacuum suction cups 24 will be activated and generate a large adsorption force, so that the nylon yarn cake can be firmly adsorbed to complete the grabbing work of the nylon yarn cake. At this time, when the central grabbing frame 22 and the two side grabbing frames 13 move, they will drive the nylon yarn cake to move together;

[0064] When the nylon yarn cake is grabbed, the servo motor 14 will start to drive the middle grabbing frame 22 and the two side grabbing frames 13 to move backward, thereby driving the nylon yarn cake to move backward together. When the nylon yarn cake moves backward to the top of the stacking assembly, the multiple vacuum suction cups 24 are closed. At this time, the nylon yarn cake will automatically fall onto the stacking assembly, completing the initial storage of the nylon yarn cake, and the next nylon yarn cake can be grabbed.

[0065] Example 3: Reference Figure 4-Figure 6 as well as Figure 9-14The technical solution of this embodiment is different from that of the second embodiment in that: the stacking assembly includes two side plates 17 fixedly mounted on the stacking platform 9, and a stacking frame 11 for stacking nylon yarn cakes is fixedly mounted on the stacking platform 9 through two supporting springs 18;

[0066] The stacking rack 11 is used to store the grabbed nylon yarn cakes, realizing temporary storage of the nylon yarn cakes, so that the stacking device can stack and transport multiple nylon yarn cakes at a time, effectively improving the transport and stacking efficiency of the nylon yarn cakes;

[0067] The stacking frame 11 is provided with a plurality of connecting openings 25, which are moving channels for the two hydraulic rods 21, so that the two hydraulic rods 21 can smoothly perform reciprocating forward and backward movement without affecting the normal stacking of the nylon yarn cakes on the stacking frame 11, and the stacked nylon yarn cakes are located between the two hydraulic rods 21, that is, the two hydraulic rods 21 will not be blocked by the nylon yarn cakes when moving. The side of the stacking frame 11 is provided with two connecting chutes, which can cooperate with the two side grabbing frames 13 to make the side grabbing frames 13 move more smoothly and conveniently;

[0068] Two sliding blocks 28 are fixedly installed on the side of the stacking frame 11, and sliding grooves 29 are provided on the two side plates 17, and the two sliding blocks 28 are slidably engaged in the two sliding grooves 29 respectively. When the nylon yarn cakes on the stacking frame 11 increase, the weight of the nylon yarn cakes will press on the stacking frame 11, thereby driving the stacking frame 11 to move downward between the two side plates 17 under the cooperation of the sliding blocks 28 and the sliding grooves 29. As the nylon yarn cakes gradually increase and the weight gradually increases, the downward movement distance of the stacking frame 11 will also gradually increase.

[0069] A supporting auxiliary mechanism is installed between the stacking frame 11 and the two side plates 17. The supporting auxiliary mechanism includes a plurality of mounting frames 27 fixedly mounted on the stacking frame 11. A linkage gear 30 is installed in each mounting frame 27 through a roller. Two connecting grooves 32 are provided on the side plate 17. Active tooth plates 31 are fixedly installed in the two connecting grooves 32, and the active tooth plates 31 mesh with the side of the linkage gear 30.

[0070] When the number of nylon yarn cakes increases, the stacking frame 11 moves downward, and the stacking frame 11 moves downward, which drives the mounting frame 27 therein to move downward. When the mounting frame 27 moves downward, the linkage gear 30 thereon moves downward synchronously. Since the linkage gear 30 is meshed with the active tooth plate 31, the linkage gear 30 can move downward and rotate forward under the action of the active tooth plate 31.

[0071] The two mounting frames 27 at the same height are provided with a push structure, which includes a driven tooth plate 33 slidably mounted in the mounting frame 27, and the driven tooth plate 33 is meshed with the upper part of the linkage gear 30, and the two driven tooth plates 33 are fixedly mounted with connecting rods, and the two connecting rods are commonly fixedly mounted with a supporting partition plate 26;

[0072] When the linkage gear 30 rotates forward, it drives the upper driven gear plate 33 meshing therewith to move forward, thereby driving the supporting partition plate 26 to move forward under the cooperation of the two driven gear plates 33 in the two mounting frames 27 and the two connecting rods;

[0073] When the stacking rack 11 moves down to a unit distance (the unit distance is the fixed distance that the stacking rack 11 moves down when each nylon yarn cake is added to the stacking rack 11), the instruction manual attachment is formed. Fig.11 In the state shown, the supporting partition plate 26 moves to the maximum distance, the driven tooth plate 33 moves to the maximum distance and cannot move, the driven tooth plate 33 and the linkage gear 30 form a contact but non-acting state, at this time the linkage gear 30 continues to rotate forward and cannot drive the driven tooth plate 33 to move, and when the linkage gear 30 rotates in the reverse direction, the driven tooth plate 33 will act on the linkage gear 30, and at this time the linkage gear 30 rotates in the reverse direction to drive the driven tooth plate 33 to move back;

[0074] When the two supporting partition plates 26 at the same height are extended, a mounting device is formed on the stacking frame 11. At this time, when the next nylon yarn cake is stacked, it will be placed on the two supporting partition plates 26. At this time, there will be a space difference between the nylon yarn cake stacked at the upper back and the nylon yarn cake stacked at the lower front, and they will not be stacked together;

[0075] By repeating the above steps, multiple nylon yarn cakes can be stacked and placed, and there is a certain gap between each two adjacent nylon yarn cakes, and they will not be stacked together, so that the loading and unloading components can select nylon yarn cakes at different heights for flexible unloading according to unloading requirements, that is, when unloading, the nylon yarn cake in the middle position can be unloaded first, rather than unloading sequentially from top to bottom, and the unloading is more flexible.

[0076] Example 4: Reference Figure 1-Figure 4 The technical solution of this embodiment is different from that of the third embodiment in that: the limiting mechanism includes two lifting limiting rods 6 fixedly installed on the inner side of the support frame 5, and two lifting sliders 12 are fixedly installed on the side of the stacking platform 9, and the two lifting sliders 12 are respectively slidably engaged and installed on the two lifting limiting rods 6;

[0077] The lifting slider 12 on the stacking platform 9 cooperates with the lifting limit rod 6 on the inner side of the support frame 5, so that the stacking platform 9 can be stably lifted and lowered vertically between the support frames 5 without being offset or separated during movement;

[0078] The lifting assembly includes a traction motor 3 fixedly mounted on the outside of the support frame 5, a traction drum 4 is mounted on the traction motor 3 through a steering gear box, a traction rope 7 is wound and connected to the traction drum 4, and the end of the traction rope 7 is fixedly connected to the stacking platform 9, a traction roller group 8 is arranged on the top of the support frame 5, and the traction roller group 8 cooperates with the traction rope 7, and a plurality of damping springs 10 are fixedly mounted between the bottom of the stacking platform 9 and the support base 1;

[0079] When the traction motor 3 is started, it will drive the traction drum 4 to rotate under the steering and transmission action of the steering gear box. When the traction drum 4 turns forward, the traction rope 7 will be reeled in, which will drive the stacking platform 9 to move upward under the cooperation of the traction roller group 8. When the traction drum 4 rotates in the opposite direction, the traction rope 7 will be released, which will automatically move the stacking platform 9 downward under the gravity of the damping spring 10 and the stacking platform 9, thereby realizing the automatic up and down movement of the stacking platform 9, thereby adjusting the height position of the stacking unit on the stacking platform 9, which is convenient for loading, grabbing, stacking and unloading, stacking and storage of nylon yarn cakes of different heights, further improving the application scope of the stacking.

[0080] The embodiment of the present invention further provides a method for stacking nylon yarn cakes for processing nylon DTY low-elastic yarn, which is used in the nylon yarn cake stacking device for processing nylon DTY low-elastic yarn, and comprises the following steps:

[0081] S1. When stacking nylon yarn cakes, first move the support base 1 to the position where the nylon yarn cakes are stacked, and adjust the height position of the stacking unit through the lifting component so that the loading and unloading components on the stacking unit are at the same height as the uppermost nylon yarn cake;

[0082] S2, control the loading and unloading components in the stacking unit through the control box 2 to start, move the top nylon yarn cake to the stacking component, and complete the initial stacking;

[0083] S3, control the lifting assembly to start through the control box 2, adjust the height of the stacking unit, move the loading and unloading assembly down to the position of the next nylon yarn cake, and start the loading and unloading assembly at the same time, move the next nylon yarn cake to the stacking assembly, and complete the stacking again;

[0084] S4. As the number of nylon yarn cakes on the stacking assembly increases, the stacking assembly will automatically adjust its height position according to the weight of the nylon yarn cakes on it, thereby realizing automatic stacking support and arrangement of multiple nylon yarn cakes;

[0085] S5, repeating steps S2-S4 until the number of nylon yarn cakes in the stacking unit reaches a maximum value, and the nylon yarn cake stacking is completed;

[0086] S6. Move the support base 1 to move the stacking unit to the shelf for storing nylon yarn cakes, start the loading and unloading components and the lifting components, and place the multiple nylon yarn cakes in the stacking component in the corresponding positions on the shelf in turn to complete the automatic unloading and storage stacking of the nylon yarn cakes.

[0087] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
