Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The tube grabbing and yarn pushing and feeding mechanism shown in fig. 1 and 2 mainly comprises a rotating shaft 1, a tube feeding driving mechanism 2 connected to the rotating shaft 1, a tube grabbing mechanism 3 connected to the driving end of the tube feeding driving mechanism 2 and a yarn pushing plate 4 connected to the driving end of the tube feeding driving mechanism 2. Wherein the yarn pushing plate 4 is used for pushing the yarn package 13, which is wound with a yarn of a predetermined length or a predetermined weight on the yarn winding station, away from the station (see fig. 4, by swinging the yarn pushing plate 4) (see fig. 4), the tube feeding driving mechanism 2 is used for driving the tube gripping mechanism 3 (connected to the driving end of the tube feeding driving mechanism 2) to grip the empty bobbin 15, and releasing the empty bobbin to the station which was pushed away before (by swinging around the rotating shaft 1, telescoping of the tube feeding driving mechanism 2, and clamping and releasing of the tube gripping mechanism 3).
The pipe gripping mechanism 3 includes a fixed piece 31 and a movable piece 32. The fixed sheet 31 is connected to the driving end of the feeding tube driving mechanism 2, and the movable sheet 32 is hinged with the fixed sheet 31. The movable piece 32 is driven by a tube gripping driver 33 shown in fig. 3. In this example, the pipe gripping driving member 33 is an air cylinder. The feeding tube driving mechanism 2 is also an air cylinder. An opening state and a closing state are arranged between the movable piece 32 and the fixed piece 31, and in the opening state, an opening between the fixed piece 31 and the movable piece 32 faces away from the yarn pushing plate 4 and is used for receiving or releasing the yarn tube at the side of the yarn pushing plate 4; in the closed state, a cavity for accommodating the yarn tube is defined between the fixed sheet 31 and the movable sheet 32, and the yarn tube is not easy to be separated from the cavity.
In this example, the fixing piece 31 is in a flat plate shape, the movable piece 32 has an arc structure with a self-centering function, and since the fixing piece 31 is in a flat plate shape and does not rotate, the fixing piece 31 can be easily inserted into Guan Ku (not shown) for preliminary positioning, and the movable piece 32 clamps the bobbin in the bobbin warehouse. Because the movable piece 32 has an arc-shaped structure, the arc-shaped structure is matched with the bobbin, the position of the bobbin can be adjusted, and the accurate positioning of the bobbin is completed so as to accurately feed the bobbin to the winding station.
In this example, a fixing plate 6 is fixed to the rotating shaft 1 through a clamping block 5 shown in fig. 1. The clamping block 5 clamps the rotating shaft 1. The fixed plate 6 is provided with a feeding tube driving mechanism 2. The driving end of the feeding pipe driving mechanism 2 is connected with the pipe grabbing mechanism 3. The fixed plate 6 can swing with the rotation of the rotation shaft 1.
The yarn pushing plate 4 is provided with guide grooves 41 at two sides, the guide grooves 41 are arc-shaped, and the guide grooves 41 are sleeved on the rotating shaft 1. The guide groove 41 in this example is formed by a ring-shaped body connected to the side edge of the yarn pusher 4. The yarn pushing plate 4 is also connected to the driving end of the feeding tube driving mechanism 2. When the tube-feeding driving mechanism 2 drives the tube-gripping mechanism 3 to move down, the yarn-pushing plate 4 also moves down, and, due to the arcuate guide groove 41 on the yarn-pushing plate 4, the yarn-pushing plate 4 has a slight swing with respect to the rotating shaft 1 when moving down, in order to make the yarn-pushing plate 4 contact the bottom of the package (see fig. 4) where the yarn of a predetermined length or weight is wound to be stirred more smoothly. The distance between the yarn pushing plate 4 and the driving end of the feeding tube driving mechanism 2 can be changed (for example, a telescopic rod sleeve is connected between the driving end of the feeding tube driving mechanism 2 and the yarn pushing plate 4), so as to allow the yarn pushing plate 4 to swing due to the arc-shaped guide groove 41.
Because the yarn pushing plate 4 is hung on the rotating shaft 1, the yarn pushing plate 4 is not easy to damage when bearing a large force, and is not easy to separate from the rotating shaft 1.
In this example, the edge of the stripper plate 4 is bent to one side to increase strength, and the bent edge 42 is shown in fig. 2. The height of the folded edge 42 can be regarded as the thickness of the stripper plate 4. The lower folded edge 42, shown in fig. 2, has a small height, i.e. a certain width and rigidity of the front end of the yarn pusher plate 4, to facilitate smooth pushing out of the yarn package 13 wound with yarn (see fig. 4).
As shown in fig. 1, one end of the rotating shaft 1 is provided with a support plate 7. The supporting plate 7 is connected with the rotating shaft 1 through a bearing. The supporting plate 7 is also provided with a rotating motor 8, the rotating motor 8 transmits power to the rotating shaft 1 to enable the rotating shaft 1 to rotate, and the rotating motor 8 and the rotating shaft 1 are in transmission through a belt 9. The rotating motor 8 is located on the same side of the support plate 7 as the rotating shaft 1, i.e., on the side close to the pipe gripping mechanism 3, thereby reducing the volume.
As shown in fig. 1, a mating guide structure composed of a convex strip 10 and a corresponding groove 11 is provided between the rotating shaft 1 and the guide groove 41. In this example, the protruding strip 10 is disposed on the outer periphery of the rotating shaft 1, connected to a collar, and located on the outer periphery of the collar. The groove 11 opens in the inner edge of the guide groove 41, or in what is called the inner side wall. And the cooperation of the ring of raised strips 10 and the grooves 11 can also allow the rotation of the yarn pushing plate 4 relative to the rotating shaft 1. The convex strips 10 are matched with the corresponding grooves 11, so that the yarn pushing plate 4 is not easy to slide in the axial direction of the rotating shaft 1. In other embodiments, the protruding strips 10 may be provided on the yarn pushing plate 4, and the grooves 11 may be provided on the corresponding collar on the rotating shaft 1.
In summary, in the tube grabbing and yarn pushing tube feeding mechanism of this embodiment, the yarn pushing plate 4 is hung on the rotating shaft 1, and the rotating shaft 1 provides support, so that the yarn pushing plate 4 can bear a large external force and is not easy to be damaged, and the yarn pushing plate 4 is not easy to be separated from the rotating shaft 1. And the opening between the fixed piece 31 and the movable piece 32 in the pipe grabbing mechanism 3 is opposite to the yarn pushing plate 4, so that a side empty bobbin can be grabbed.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
