Description

Technical field

[0001] The invention relates to the technical field of polyester filament transportation, in particular to an automatic tail yarn reversing device for winding tail yarns in opposite directions. [Background Technology]

[0002] As a key production equipment for polyester filament, the number of winding machines used is also increasing. Many domestic polyester filament production companies have large-scale winding machine production lines, and a large number of packages need to be transported every day. Especially when it comes to the transportation of pre-oriented yarns and fully stretched yarns, manual intervention by yarn dowsers is required to uniformly load the tail yarns of the packages. Domestic polyester filament production companies are gradually reducing their dependence on labor and making extensive use of automated transportation systems. The tail yarn reversing equipment is an important component of the automated transportation system and is used in the automated yarn doffing process. It can be used in the automated yarn doffing process in which the tail yarns of the packages on the two spindles of the two doffing machines are in opposite directions, and it is also suitable for the automated yarn doffing process in which the tail yarns of the packages on the two spindles are in the same direction. However, in the existing tail yarn reversing process, since the automatic doffing robot used in the automated yarn doffing process does not have the functionality of tail yarn reversing, a large number of yarn dowsers are required to participate in the tail yarn reversing process, which reduces the efficiency of package transportation. [Summary of the invention]

The second tail yarn reversing device 200 includes a second support assembly 81, a second rotary reversing mechanism 8, and a second pushing mechanism. The second support assembly 81 is provided with a plurality of second support beams 811. The second support assembly 81 is mounted on the second rotary reversing mechanism 8. Driven by the second rotary reversing mechanism 8, the second support beams 811 rotate and reverse, connecting with the first tail yarn reversing device 100, the automatic doffing robot, or the yarn cart. The second pushing mechanism includes a synchronous belt linear module 10, and a cake pushing mechanism 101 slidably mounted on the synchronous belt linear module 10. The cake pushing mechanism 101 moves horizontally under the drive of the synchronous belt linear module 10. The second tail yarn reversing device 200 completes the linear motion of the cake pushing mechanism 101 through the synchronous belt linear module 10, thereby pushing the package.

[0025] Further, see Figure 4 The first rotary reversing mechanism 5 includes a reversing cylinder 51, a swing arm 52, and a first slewing bearing 53. The reversing cylinder 51 is movably mounted on the hinged seat 6. The telescopic cylinder of the reversing cylinder 51 is hingedly connected to the swing arm 52. The swing arm 52 drives the first slewing bearing 53 of the rotating assembly 2 to rotate. The rotating assembly 2 is mounted on the lower frame assembly 3. The first tail wire reversing device 100 is driven by the reversing cylinder 51 to rotate the swing arm 52 mounted on the first slewing bearing 53, thereby driving the first support assembly 1 to complete rotational alignment.

[0026] Further, see Figure 2 The first pushing mechanism includes a pushing cylinder 14 and a pushing assembly. The pushing assembly is slidably mounted on the first support beam 11, and the telescopic cylinder of the pushing cylinder 14 is connected to the pushing assembly. In this embodiment, a set of first support beams 11 is provided on the first support assembly 1, including two first support beams 11 arranged sequentially from top to bottom. The pushing assembly includes two push sleeves 12 slidably mounted on the first support beams 11, and a push rod 13 connected between the two push sleeves 12. The pushing cylinder 14 is connected to the push rod 13.

When the reversing cylinder 51 pushes the rotating assembly 2 to rotate 90° to reach the required position, the reversing cylinder 51 is protected and the hard limit column 42 hard limits the position to mitigate and absorb the impact energy when rotating into position, protecting the overall structure and the cylinder from damage.

[0030] Working process of the present invention:

[0031] S1. The first tail yarn reversing device 100 and the cantilever shaft of the automatic doffing robot that needs to change the tail yarn direction are aligned to complete the process docking. After the automatic doffing robot completes the doffing process of the two spindles with the tail yarns in opposite directions, Figure 1 The first rotary reversing mechanism 5 drives the first support assembly 1 to align the cantilever shafts of the automatic doffing robot that need to change the direction of the tail wire, and pushes the package that needs to change the direction of the tail wire to the two first support beams 11 of the first tail wire reversing device 100.

[0032] S2. Align the second tail yarn reversing device 200 and the cantilever shaft of the automatic doffing robot that does not need to change the tail yarn direction to complete the process docking. Figure 1 The second rotary reversing mechanism 8 in the automatic doffing robot is aligned with the cantilever shaft without changing the tail yarn direction, and the package is pushed to the two second support assemblies 81 of the second tail yarn reversing device.

[0033] S3. After the automatic doffing robot pushes the wound package completely to the tail wire reversing device, a new round of doffing process can be put into place. The first tail wire reversing device 100 is driven by the first rotary reversing mechanism 5 to align the first support assembly 1 with the second support beam 811 of the second tail wire reversing device 200. The ejection cylinder 14 in the first support assembly 1 pushes the ejection assembly to drive the package. The package that needs to change the tail wire direction can be pushed onto the two second support beams 811 of the second tail wire reversing device 200. At this point, the tail wire reversing process is completely completed.

[0034] S4. The second rotary reversing mechanism 8 in the second tail yarn reversing device 200 completes the docking with the yarn vehicle transporting the package, thereby completely unloading the package and playing the role of temporary storage and transfer of the package.

[0035] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
