In one aspect of the invention, a kind of bobbin-winding machine that has yarn guiding device as claimed in claim 1 is disclosed.

Dependent claims relates to preferred, advantageous embodiments of the present invention.

Description of drawings

The mode by example is merely provided but the present invention of being not limited to this makes statement below in conjunction with accompanying drawing, wherein:

Fig. 1 is the front elevation that has the bobbin-winding machine of improved yarn guiding device according to of the present invention;

Fig. 2 and Fig. 3 illustrate according to the yarn guiding device of Fig. 1 two schematic top plan view in two reversal phase of yarn guide motion, have wherein removed some parts to describe the other parts.

The specific embodiment

With reference to the accompanying drawings, the bobbin-winding machine that has improved yarn guiding device represents that with reference number 1 it comprises a yarn yarn tube 2 that is arranged on the turning cylinder 3, and yarn tube 2 is driven successively by motor 4 or a tangent line pressure roller 4a.Bobbin-winding machine 1 also comprises a yarn guiding device 5, and it has a guide plate to promote the winding of yarn on yarn tube 2.

Yarn guiding device 5 comprises the sliding rack 6 of a motion on guide plate 7, its centering guide basically with the parallel axes of yarn tube 2.

Sliding rack 6 is provided with first connecting device 8 that is used for two bands, chain or belt 9,10; Belt 9,10 is realized a continuous reverse motions under corresponding motor 11,12 drives, and sliding rack 6 is moved between two positions " A " and " B ".

Belt 9,10 preferably stacks together, and they all are wound on two wheels or the pulley, and wherein one of two wheels is idle pulley, and another one is for connecting the drive wheel of corresponding motor 11,12.

Belt 9,10 includes second connecting device 13,14, and they are alternately with 8 collaborative works of first connecting device.

Sliding rack 6 changes to another belt of connection from connecting a belt for convenience, and strut member 15,16 (being illustrated as plate) can be set, and when the connection of sliding rack 6 changed motion, above-mentioned strut member limited may moving of belt 9,10.Particularly, strut member 15,16 provides support and with the swing of restriction belt 9,10, makes to avoid belt 9,10 excessively moving transversely.The position of strut member 15,16 is located substantially near position " A " and " B ", and these positions are corresponding to the connection conversion part of second device 13,14 with first device 8.

Position " A " and " B " have shown the joining of second connecting device 13,14, but also are the functions of the coiling length L of yarn tube 2.Described position " A " and " B " are unfixing but changeable, and all can change in sliding rack 6 strokes.For obtaining this effect, change two belts 9,10 or just the moving velocity of one of them belt is just enough.

For example, position " A " is nearest apart from the center of yarn tube 2 if desired, can reduce the moving velocity of belt 10 or the moving velocity of raising belt 9, or the moving velocity of reduction belt 10 also also improves simultaneously the moving velocity of belt 9.

In the illustrated embodiment, first connecting device 8 and second connecting device the 13, the 14th, mechanical type is connected, but clearly also can be with the connecting device of other type, for example electromechanical, electromagnetic type, magnetic-type or the like.

In more detail, first connecting device 8 comprises that each all comprises a slide block 18,19 with sliding rack 6 bonded assembly pivots 17, the second connecting devices 13,14, and slide block 18,19 faces with each other, and when slide block 18,19 intersects, can alternately hold pivot 17.

In the practical application, when slide block 18,19 in the position " A " and " B " when locating to intersect, because the special surface shape of each slide block 18,19, pivot 17 has just changed the slide block that is connected.

As shown in the figure, each slide block 18,19 comprises two surperficial 18a, 18b; 19a, 19b.18a, 19a have the bight that can brake pivot 17 on the surface.In fact each surperficial 18a, 19a all is positioned at the downstream of the moving direction of each root belt 9,10, has so just formed a restriction that drags to pivot 17, on the other hand, surperficial 18b in addition, 19b is rounded, and they play the effect of the guiding shape that is used for pivot 17 conversion.Belt 9,10 must move on two parts: the part that length is less is included between position " A " and " B " and also represents that with reference number 20 it is equivalent to the coiling length L of yarn tube 2 basically; With long another part that reference number 21 is represented, it is equivalent to the outer side path part of position " A " and " B ".

Because second connecting device 13,14 has to intersect at a some place, wish yarn guiding device 5 counter motions at this some place, therefore " A " and " B " locates in the position, motor 11 and 12 must make in the belt 9,10 quicken to move periodically, thereby improve the moving velocity on long part 21, and make with in bonded assembly first connecting device 8 one of in second device 13,14 and second device 14,13 another and arrive the reverse position of motion simultaneously.

Therefore, second connecting device 13,14 moves past part 20 and 21 in the identical time " t ", wherein should the time except that other factors, by the winding speed decision of yarn tube 2.

Control unit 22 controls are used for the motor 11,12 of driving belt 9,10 and are used to rotate the motor 4 of yarn tube 2.

By means of the motor 11,12 that is used for driving belt 9,10 and the control unit that is used to rotate the motor 4 of yarn tube 2, also may obtain difform yarn yarn tube.

By the moving velocity homogeneous of the belt 9,10 in the winding part 20 that keeps yarn tube 2, can obtain the yarn tube 2 of cross winding.

Moving velocity by the belt 9,10 in the above-mentioned winding part 20 that makes yarn tube 2 is inhomogeneous, can obtain yarn cone, double end awl yarn tube or the like.

It should be noted that under the situation that does not need the mapped structure element,, just can obtain to have difform yarn tube 2 only by utilizing the suitably control unit 22 of drive motor 11,12.

On the other hand, with comparing with the existing solution of motor or magnet direct drive yarn guiding device, owing to there is not the motion of transmitting device to be detained constantly, the reverse moving velocity of yarn guiding device is obviously bigger.

In fact, according to the present invention, two belts 9,10 are done unidirectional moving along opposite direction, and---except needing slight the acceleration for move past the longest part 21 when moving past part 20---motor 11,12 that drags belt 9,10 does not stop and makes yarn guiding device 5 do counter motion, and yarn guiding device 5 has been changed and the different connections that drags band.Therefore according to the present invention, it is possible that the advantage of the speed aspect of yarn guiding device and the advantage that can realize the control variety aspect of electronic or electronic operation yarn guiding device are combined, and yarn guiding device wherein is subjected to the Mechanical Driven of two unidirectional moving belts moving in opposite direction.
