Description

[Detailed Description of the Invention] The present invention relates to a yarn end suction device in a yarn winding device or the like.

When winding up a yarn in a spinning device or a winder, if a slab or the like is found in the yarn or the yarn is cut, the yarn end on the winding side and the yarn end on the sending side are connected to a yarn end suction device. The suction mouse of the yarn end suction device rotates in a virtual vertical plane around one point to guide the yarn ends to the knotter. However, it is difficult to guide the yarn between the knitting roller and the delivery roller, which are used to guide and send out the yarn, using only the rotational movement. Therefore, the suction mouse must have a complex movement trajectory, such as a turning movement and, in addition, a movement in a direction perpendicular to the turning movement, in order to guide the yarn to the nip point between the nip roller and the delivery roller. First, a movement mechanism was needed for this purpose.

The device of the present invention eliminates this drawback, and uses a suction mouse to move on a virtual plane that intersects with a virtual vertical plane so that the line of intersection appears horizontal. It is characterized by supporting a suction pipe provided with a mouth.

Next, an example in which the device of the present invention is implemented in an air spinning device will be described below.

Reference numeral 1 denotes a fixed frame, with an air spinning unit 2 on the top, a slab catcher 3 and a winding section 4 on the front, and a yarn splicing cart 7 attached to the frame by guide rails 5 and 6 inside. It is installed so as to be movable in the longitudinal direction (direction perpendicular to the plane of the paper in FIG. 1).

The air spinning unit 2 includes a draft part 11 consisting of a back roller 8, a middle roller 9, and a front roller 10, an air spinning nozzle 12, a roller pair consisting of a delivery roller 13 and a nip roller 14,
It consists of a suction tube 15 such as cotton wool.

The winding section 4 is formed by pressing a package 22 against a friction roller 23 by a cradle 21 rotatably supported by a shaft 20.

The yarn splicing cart 7 includes a suction pipe 30 for suctioning the yarn end on the sending side, a suction pipe 31 for suctioning the yarn end on the winding side, a blower 32 for generating a suction air flow in each of the suction pipes 30 and 31, and a knotter 33. It has a lot of information. The suction pipe 30 for suctioning the yarn end on the feeding side has a suction mouth 34 at its tip, has a C-shaped side surface, and has a base 36 rotatably supported by a bearing member 35. The suction pipe 30 bent into a C-shape and the base 36 are bent at right angles. A suction pipe 37 connected to the blower 32 is connected to the base 36 . The bearing member 35 is supported by a support member 39 inclined at an angle θ with respect to a vertical fixing plate 38 of the yarn splicing carriage. That is, the vertical fixing plate 38 is arranged on a virtual plane A' (second
The support member 39 is located on the virtual plane B (Fig. 2) that intersects the plane A' at an angle θ with the line of intersection being horizontal. The base 36 supported by the bearing member 35 supported by the bearing member 39 is perpendicular to the virtual plane B.
And a suction pipe 30 bent in a C shape.
is perpendicular to the base 36, so the suction pipe 30 is located on a virtual plane B' (FIG. 2) parallel to the virtual plane B, and the suction mouth 34 is also on the same plane.
It will draw a trajectory on B′ and turn. That is, the suction mouth 34 is used for the sliver and yarn Y.
The nip roller 14 draws a trajectory on a virtual plane B' that intersects the virtual vertical plane containing the nip point at an angle θ in a horizontal state with the virtual vertical plane containing the nip point.

A fan-shaped gear 41 is connected to the support member 39 by a shaft 40.
support. The fan-shaped gear 41 meshes with a gear 42 provided integrally with the base 36. Sector gear 41
A rod 43 that reciprocates by swinging a cam plate (not shown) is pivotally supported.

The winding side yarn end suction suction pipe 31 is rotatably supported by a support member 45, and a suction mouth 44 at the tip approaches the package 22 to suck the package side yarn end and guide the knotter 33.

Next, the operation of the device of the present invention will be explained.

Sliver S pulled out from Kens 16 is
Draft part 1 via guide rollers 17 and 18
1, the yarn is spun by an air spinning nozzle 12, passed through a pair of rollers including a nip roller 14 and a delivery roller 13, and wound up into a package 22.
During this time, the slab catcher 31 performs slab detection, thread breakage sensing, etc. When a slab is detected and the yarn is cut, the suction pipes 30 and 31 rotate based on the signal, sucking the yarn end on the sending-out side and the yarn end on the winding-up side. Guide the thread to the knot 33 and tie it.

During the yarn tying operation, the suction pipe 30, which was in the position shown by the dashed line in FIG. Aspirate the ends. This movement is caused by the movement of the sector gear 4 as the rod 43 moves due to the operation of a cam plate (not shown).
1 rotates, and the gear 42 that meshes with it rotates,
The suction pipe 30 rotates via the base 36 which is integral with the gear 42.

By turning the suction pipe 30 as described above, the suction mouth 34 pulls out the yarn Y from the air spinning nozzle 12 as shown by the dashed line in FIG. The reason for this is that, as described above, the suction pipe 30 is supported so that the rotation is performed on a plane inclined by an angle θ with respect to the virtual vertical plane. is guided to the knotter 33 at a position that is deviated from the normal winding course shown by the solid line in FIG. . Therefore, when the yarn comes into contact with the slope 19, as the roller rotates, the yarn Y comes off the slope of the nip roller 14, comes into contact with the delivery roller 13, and as both rollers further rotate, the yarn enters the nip point of both rollers. I will do it.

Therefore, the thread Y guided by the suction mouth 34
Immediately, the delivery roller 13 and the Nitsu Pro roller 1
There is no need for the suction pipe or the suction mouth to make complicated movements such as entering the nip point between the rollers 4 and 4 and guiding the thread to the nip point of both rollers.
