Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device in a spindle winder that reduces the traverse length as the diameter of the spool to be wound increases, thereby forming the end of the spool into a tapered shape.

In the conventional end forming device, a member for regulating the traverse length of the thread guide is fitted into a grooved cam piece, and as the winding diameter of the thread body increases, the grooved cam piece tilts to gradually adjust the traverse length of the thread guide. However, to be more precise, the traverse lengths of the thread guide were not equal on the left and right sides.

The purpose of the present invention is to improve such conventional drawbacks and to obtain a high-quality thread body by a simple means by making the traverse length of the thread guide equal on the left and right sides. In a device that regulates the traverse of a thread guide by tilting a grooved cam piece that interlocks with the spindle as the cam increases, one of two pins provided at one end of the swinging piece is inserted into a long groove in the traverse direction provided on the grooved cam piece. A groove perpendicular to the traverse direction provided in a traverse slide piece that is loosely fitted to move in the length direction of the long groove and the other end of the pin moves in the traverse direction along the guide shaft in conjunction with the traverse cam. The other pin is rotatably and loosely engaged with the regulating slide piece that moves along the guide shaft, and the pin provided at the other end of the swing piece is loosely engaged with the regulating slide piece that moves along the guide shaft. The yarn guide is loosely engaged with a groove perpendicular to the traverse direction provided in a yarn guide holder that moves in the traverse direction along the traverse direction, and the yarn guide is provided on the yarn guide holder.

Embodiments of the present invention will be described with reference to the drawings.

In Figures 1 to 3, 1 is a machine frame, 2 is a fixed shaft, and 3 is a grooved cam piece whose central part is connected to the fixed shaft 2 and is tiltable. A long groove 4 is provided in the traverse direction. Reference numeral 5 denotes an actuating lever which rotates via a linking rod 6 that is linked to a spindle as the winding diameter of the spool increases, and a protrusion 5a at the tip thereof is loosely engaged with the long groove 4. Therefore, the rotation of the operating lever 5 causes the grooved cam piece 3 to tilt as the winding diameter of the thread body increases.

A traverse slide piece 7 is provided to move along a guide shaft 8 fixed to the machine frame 1, and a slider 7b provided on this piece is engaged with a cam groove of a traversing cam 9, and the traverse slide piece 7 is moved along a guide shaft 8 fixed to the machine frame 1. As the cam 9 rotates, it moves on the guide shaft 8 in the traverse direction. The guide shaft 8 is further provided with a regulating slide piece 10 movably in line with the traverse slide piece 7.

Reference numeral 11 denotes a thread guide holder equipped with a pulley-like thread guide 12, which is moved in the traverse direction along a guide shaft 13 fixed to the machine frame 1.

The aforementioned traverse slide piece 7 and thread guide holder 11 were provided with grooves 7a and 11a perpendicular to the traverse direction, respectively, and the regulation slide piece 10 was provided with a circular hole 10a.

Reference numeral 14 denotes a swinging piece provided between the slide pieces 7, 10 on the guide shaft 8 and the thread guide holder 11 on the guide shaft 13 above it, and two pins 15,
16, one pin 17 is provided at the top,
The lower pin 15 loosely engages with the long groove 4 of the grooved cam piece 3, and the other end of the pin 15 loosely engages with the groove 7a of the traverse slide piece 7, and the other lower pin 16 is used for regulating purposes. It is rotatably loosely fitted into the circular hole 10a of the slide piece 10, and furthermore, the pin 1 on the upper part of the swing piece 14
7 is loosely engaged with the groove 11a of the thread guide holder 11.

In the above configuration, the traverse slide piece 7 reciprocates a predetermined amount on the guide shaft 8 by driving the traversing cam 9, and moves the swing piece 14 in the same direction via the pin 15 that engages with the groove 7a. The thread guide holder 11 is not connected to the thread guide holder 11 and engages with its upper pin 15 through the groove 11a.
is moved along the guide shaft 13 to traverse the thread guide 12. At this time, the regulating slide piece 10 engaged by the pin 16 is also moved along the guide shaft 8 together with the slide piece 7 while winding the thread. As the winding diameter of the spool increases, the grooved cam piece 3 is tilted by rotating the operating lever 5 to gradually reduce the traverse length by the thread guide 12, thereby forming a taper at both ends of the spool.

The above operation is shown diagrammatically in FIG.

In the same figure, A, A ₁ , A', A' ₁ are pins 1 of the rocking piece 14.
7, B, B ₁ , B', B' ₁ is pin 15, C, C ₁ , C',
C′ ₁ indicates the position of pin 16, and right triangle ABC,
A′B′C′, A ₁ B ₁ C ₁ , A′ ₁ B′ ₁ C′ ₁ indicates that the long groove 4 of the grooved cam piece 3 is Y with respect to the slide axis X of the guide shaft 8,
Each pin 15, 16 in the state tilted to Y ₁ ,
17, and the distance between A and A' on the left and right as well as _A1 and _A'1 is the moving length of the pin 17, that is, the traverse length of the thread guide 12, and the traverse length is reduced from l to _l1 . Status is indicated.

Now, if we look at the traverse state in FIG. 5 when the long groove 4 in FIG. 2 is tilted to the Y position in FIG.
The intersections of the perpendicular lines from B' to X are M, M', A,
Let NN' be the intersection of the perpendicular to the extension line from A' to MB and B'M', then in the triangular BCM, B'C'M'=''='' Therefore, therefore, ∠CBM = ∠C' B′M′ ∠ABN=∠A′B′N′ =′′ Therefore =′′ MO=OM′ Therefore +=′+′′.

As shown in FIG. 1, the pin 17 is loosely fitted into the groove 11a of the thread guide holder 11 and moves at right angles to the traverse direction, so the thread guided by the thread guide 12 moves equally on the left and right sides with respect to the midpoint O of the traverse. Due to the inclination of the grooved cam 3, the traverse length is reduced equally on the left and right sides, and the tapered ends of the thread body become equal on the left and right sides.

In this way, according to the present invention, three pins 1 are attached to the swinging piece 11 which serves as a member for regulating the traverse length.
5, 16, 17 are disposed, and the swinging piece 14 is engaged with the grooved cam piece 3, and the traverse slide piece 7 whose movement direction is controlled in the traverse direction, the regulating slide piece 10, and the thread Guide holder 1
Since it is movably engaged with 1, it has the effect of accurately and evenly tapering the left and right sides.
