Description

Technical Field

[0001] The utility model relates to the field of textile machinery, in particular to a can replacement device. Background Art

[0002] In the textile production process, the replacement of cans is a frequent and important operation. That is, after the receiving can is wound at the can winding station, it is pushed by a pushing unit and moved from the can winding station to the can delivery station for standby. Simultaneously, the spare cans in the can standby station are moved to the can winding station to complete the can replacement. Friction during the movement of the cans on the mobile platform shortens the can's service life, and greater driving force is typically required to overcome the friction between the cans and the mobile platform. In existing technologies, multiple casters are typically installed at the bottom of the can to reduce the driving force required to move the cans. However, cans with casters are subject to significant friction during movement, and this friction increases with the weight of the can. Greater friction loads require greater driving force. Furthermore, the casters are prone to getting stuck or damaged during the can's movement. Damage to the can or its inability to move smoothly can lead to unnecessary production delays. Furthermore, the casters cannot guarantee smooth movement of the cans along the conveying path. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] like Figure 2As shown, a can replacement device according to the present invention includes a mobile platform 4 and a pushing unit 5 that drives the cans to move on the mobile platform 4. The mobile platform 4 is provided with a can standby station 41, a can winding station 42, and a can delivery station 43 along the can conveying path. The can standby station 41 is used to store empty spare cans. The can winding station 42 is provided with a turntable 6. The cans receive yarn as they rotate with the turntable 6. When the yarn wound in the can reaches a set length or weight, the push unit 5 moves the spare can in the can standby station 41 to the can winding station 42, and the completed can is replaced.

[0019] The can replacement device is set at the downstream of the textile drafting machine and is used to process the yarn after drafting. Figure 2 As shown, the textile drafting machine is a key piece of equipment in the spinning preparation process. It comprises a sliver frame 1, a leveling zone 2, and a drafting zone 3. The sliver frame 1 is used to feed slivers from multiple feed cans into the leveling zone 2. The leveling zone 2 is used to adjust the uniformity and quality of the slivers in preparation for subsequent drafting. The drafting zone 3, located downstream, further processes the slivers from the multiple cans, including stretching and combining, to form slivers with a certain linear density and quality. The processed slivers are fed into a rotating can winding station 42 and stored in cans on a turntable 6.

[0020] The push unit 5 comprises a guide rail 51 positioned to the side of the can conveying path; an adjustable indexing plate 52 that slides on the guide rail 51; two sets of clamping arms 53 pivotally connected to the adjustable indexing plate 52 at intervals; and an actuator 54 for sliding the adjustable indexing plate 52. The clamping arms 53 are pivotally connected to the adjustable indexing plate 52 via a pivot shaft secured with a torsion spring. The distance between the two sets of clamping arms 53 can be adjusted according to the can diameter. In this embodiment, the actuator is a pneumatic cylinder. The end of the cylinder's piston rod is connected to the adjustable indexing plate 52, and the connection position between the piston rod output end and the adjustable indexing plate 52 is adjusted according to the required travel distance.

[0021] During operation, the piston rod of the cylinder extends, and the clamping arm 53 drives the wound can to move from the can winding station 42 to the can delivery station 43. Then, the piston rod of the cylinder retracts and drives the adjustable indexing plate 52 to reset. At the same time, the clamping arm 53 at the front end rotates due to the obstruction of the can and returns as the piston rod of the cylinder retracts. Under the elastic reset action of the torsion spring, the clamping arm 53 extends outward to the initial position.

[0022] In this embodiment, the pushing units 5 are provided in multiple groups, including: one group with an actuator stroke located between the can winding station 42 and the can delivery station 43; one group with an actuator stroke located between the can standby station 41 and the can winding station 42; and one group corresponding to the group that drives the spare can into the can standby station 41. After the can is wound at the can winding station 42, it is pushed to the can delivery station 43 for further processing. Simultaneously, the pushing units 5 with a drive stroke located between the can standby station 41 and the can winding station 42 push the empty spare can onto the turntable 6 of the can winding station 42. During this process, another spare can is moved along a predetermined path along the feed end to the can standby station 41, completing a complete can movement cycle. The close connection of the multiple pushing units 5 allows the cans to move smoothly on the movable platform 4.

[0023] The mobile platform 4 includes a support platform and a ball transfer unit 6 mounted on the support platform. The ball transfer units 6 are evenly distributed on the support platform and include a mounting shell 61 and bearing balls 62 that roll within the mounting shell 61. Several small supporting balls 63 are mounted between the mounting shell 61 and the bearing balls 62.

[0024] The mounting shell 61 provides external support and accommodation space for the entire ball transfer unit 6 , ensuring that the bearing balls 62 can roll inside it when subjected to the friction force of the can, and drive the can transfer under the drive of the actuator 54 .

[0025] The support balls 63 play a key auxiliary role between the mounting shell 61 and the load-bearing balls 62. On the one hand, they separate the load-bearing balls 62 from the mounting shell 61, avoiding direct contact between the load-bearing balls 62 and the mounting shell 61, thereby further reducing friction. On the other hand, the support balls 63 can make the rolling of the load-bearing balls 62 smoother and more stable. Multiple support balls 63 are evenly distributed around the load-bearing balls 62, supporting the load-bearing balls 62 from different directions, so that the load-bearing balls 62 can rotate in all directions with extremely low friction. When the load-bearing balls 62 are subjected to pressure from the can and roll, the support balls 63 will also roll and adjust their positions to adapt to the movement of the load-bearing balls 62, ensuring the stable operation of the entire ball transfer unit 6.

[0026] This structure enables the strip drum to move easily on the mobile platform 4, effectively reducing the driving force required for the movement of the strip drum; especially for the strip drum that has completed winding, due to its heavy weight, the friction between it and the mobile platform 4 during movement is also large, so it is easy to be damaged. This structure replaces the traditional sliding friction with rolling friction, which greatly reduces the friction load between the strip drum and the mobile platform 4, and significantly extends the service life of the strip drum; since the friction between the strip drum and the mobile platform 4 is extremely low, the strip drum can move smoothly on its conveying path, thereby improving the strip drum conveying efficiency.

[0027] Preferably, at least three ball transfer units 6 are required at the bottom of the can to provide support to prevent the can from tipping over, so the arrangement of the ball transfer units 6 is designed according to the can with the smallest diameter.

[0028] Furthermore, the ball transfer unit 6 is arranged in the can conveying path area of ​​the entire spinning workshop. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered as the scope of protection of the present invention.
