Description

Sliver can with strand ends and strand end placement method

Technical Field

The invention relates to a method for placing the tail end of a fiber strand on a can and the can with the tail end of the fiber strand, belonging to the field of textile machinery.

Background

Can is widely used in spinning mills, is a container for storing slivers (slivers), and places slivers rings produced by a carding machine, a drawing frame and a combing machine in the can for the next equipment; the next device is drawing frame, roving frame, rotor spinning machine and vortex spinning machine. At present, the cans of spinning mills mainly comprise round cans and rectangular (rectangular) cans. The slivers are placed in the sliver cans one circle by one circle through the sliver coiling disc to form sliver columns, when the specified length or the preset length is reached, the carding machine, the drawing frame and the combing machine automatically change the cans, the sliver cans filled with the slivers are pushed out, the empty cans are placed in, the operation is circulated, and the slivers are filled in the sliver cans.

However, during this automatic creeling, the strand ends are randomly placed on the top layer of the strand column at the top of the creel. There are two significant disadvantages. One disadvantage is that: when the can with the randomly placed beard strip tail end is connected, a vehicle stop worker needs to find the beard strip tail end from the top end of a beard strip column through hand-eye cooperation, then pull the tail end out, and feed the tail end to the next process. Another disadvantage is that: with the development trend of automation and intellectualization of spinning plants, the automatic joint of the fiber strand of the sliver can is lifted to schedule, the mode that the tail end of the fiber strand is randomly placed at the top end of the sliver can not accurately position the tail end of the fiber strand, the automatic searching of the tail end of the fiber strand is very difficult to realize, and the fibers of the fiber strand have bonding tendency, so that the fibers of the fiber strand are very easy to contact with surrounding fiber strand layers in the process of grabbing the tail end of the fiber strand, thereby causing the damage of the fiber strand.

The invention CN204369274U provides a method for manufacturing a round sliver can, which adds a telescopic guide structure on the prior sliver can to solve the defect that the slivers are easy to wind and break yarns in the sliver can. However, this invention does not relate to the way the strands are placed in the can and how the tail ends of the strands are placed. The invention CN2498127Y provides a manufacturing method of a flat can (rectangular can), and the method can simplify the production process and reduce the production cost. However, it does not relate to the way the strand is placed in the can and the way the strand is placed at the end after the can is filled.

Disclosure of Invention

Aiming at the defect that the tail end of the fiber strand is randomly placed on the top layer of the can at present, the invention provides a novel method for placing the tail end of the fiber strand on the can and the can with the hanging fiber strand tail end. The tail end of the fiber strand is suspended and placed on the outer sides of the fiber strand column and the fiber strand drum wall, and a certain length is kept, so that the tail end of the fiber strand which is easy to grab is obviously formed. Therefore, on one hand, a vehicle stop worker can easily grab the tail end of the beard strip to perform manual joint; on the other hand, for an automatic joint device, the tail end of the beard strip can be easily and directly grabbed, and meanwhile, the beard strip layer cannot be damaged, and the beard strip cannot be damaged.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

The first embodiment is as follows:

this embodiment is a round can. Referring to fig. 1 and 2, fig. 1 is a schematic side view of a circular can a with a strand tail end 2, and fig. 2 is a schematic top view of the circular can a with the strand tail end 2. The round can A consists of a can wall 4, a can tray 5, a can spring 6 and a pulley 7. The diameter range of the round bar barrel A is 300-1500 mm. The diameter of the round can A described in this embodiment is 400 mm.

In the process of putting the fiber strand 3 on the can A, the fiber strand 3 is put on the can tray 5 of the can A in a circle; the can pallet 5 is supported by the can spring 6, and as the weight of the whisker 3 increases, the can spring 6 is compressed, thereby keeping the top layer of the whisker column 1 at or above the top of the can a. When the fiber strand 3 in the can a reaches a specified length or a preset length (4000 m in this embodiment), that is, the specified capacity of the can a is reached, the fiber strand 3 forms a fiber strand column 1. At the same time, the strand 3 forms a strand end 2 on the outside of the strand column 1 and the can wall 4. This strand end 2 naturally hangs outside the can wall 4 and strand column 1, forming a distinct easily graspable "strand tail". Because the can A is a cylindrical structure, the strand tail end 2 is suspended at any position outside the can wall 4 and the strand column 1 according to the circular symmetry characteristic. This facilitates direct grasping without requiring that the can a must be fixed in a certain orientation. In order to reduce waste of the bundle of fibers 3 and to facilitate grasping, the length H of the tail end of the bundle of fibers is in the range of 5mm to 1500mm, preferably in the range of 30mm to 800 mm. The length H of the tail end of the strand in this embodiment is 400 mm.

Example two:

the rectangular can B has the advantages of small floor area and larger capacity for storing the fiber strands 3 compared with the circular can A. Referring to fig. 3 and 4, fig. 3 is a schematic side view of a rectangular can B with a strand end 2, and fig. 4 is a schematic top view of the rectangular can B with the strand end 2. The rectangular can B has 2 symmetrical long sides L and 2 symmetrical short sides W. In actual production, the size of the rectangular bar can B is as follows: the length X, width X and height are (600-. The rectangular can B of the present embodiment has a length, width and height of 900x225x1000 mm.

The fiber strand 3 is placed in the mechanical sliver can B in a circle, and the fiber strand 3 is placed on a supporting plate 8 of the rectangular sliver can B in a circle; at the same time, the rectangular can B reciprocates back and forth. When the whisker 3 reaches a specified length or a preset length (5000 m in this embodiment), a whisker column 1 is formed. At the same time, the strand 3 forms a strand end 2 on the outside of the strand column 1 and the can wall 4. This strand end 2 naturally hangs outside the can wall 4 and strand column 1, forming a distinct easily graspable "strand tail". The rectangular can B has two long sides L and two short sides W. The strand end 2 can be either outside the long side L or outside the short side W. Preferably, the tail end 2 of the strand of beard is located outside the short side W of the rectangular bobbin B and is easier to be grasped by the vehicle stop. Further, in order to reduce waste of the bundle of fibers 3 and to facilitate grasping, the length H of the tail end of the bundle of fibers is in the range of 5mm to 1500mm, preferably in the range of 30mm to 800 mm. The length H of the tail end of the strand in this embodiment is 200 mm.

Various modifications or additions may be made or equivalents may be substituted for those skilled in the art without departing from the spirit and scope of the invention as defined in the claims.
