Claims.
The present invention relates to winding machines for winding packages of yarn, thread, cord, or other strand material, and more particularly to a. dog mechanism for such a machine.
The present invention has, therefore, as its principal object the provision of a new and improved form of dogmechanism for yarn windin machines.
A further object of the invention is the provision of a dog mechanism for a ccning machine in which the motion of the traverse back is not restrained in one direction of movement by a force which is necessary to enable the mechanism to lock when turning in the opposite direction.
And still another object of the invention is the provision of a dog mechanism of the class described which eliminates the braking action of the traverse back as it moves in a clockwise direction during the winding operation.
Yet another object of the invention is the provision of a dog mechanism which eliminates the backpressure of the button guide so as to insure straight cones without dips in the sides thereof.
Still another object of the invention is the provision of a dog mechanism which is simple in construction, relatively inexpensive to construct, highly effective in use, and of longer life than prior dog mechanisms.
To these and other ends, the invention resides in certain improvements and combination of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.
In the drawings:
Fig. 1 is a partial view of a yarn winding machine showinga form of dog mechanism used L prior to the present invention;
Fig. 2 is a view taken substantially on line 2-2 of Fig. 1 showing the braking apparatus of the dog mechanism shown in Fig. 1;
is aside'view of a portion of a yarn winding niachine' showing a dog mechanism con- 'str-ucted'in accordance with the preferred em-- bodimentof the present invention; and
2 tions, etc. A typical example of this type of machine is shown in Fig. 1. In this figure, the yarn H is wound onto a paper cone l2 which revolves in a clockwise direction. The yarn is guided onto the cone by the reciprocating button guide l3 which is connected by means of the traverse arm I to a cam, not shown, which revolves about the point [5. The traverse arm I4 is mounted in a slot in the traverse back It which is pivoted at the point 15 in such a manner that it may move back as the cone fills up, allowing the button guide to be continuously, but slightly, pressed against the surface of the cone. The yarn II is pulled from the bobbin I! through the tension gate I8, through the slub catcher l9, underneath the stop lever 20 and to the button guide 13. 7
Figs. 1 and 2 show a sketch of the present form of dog mechanism which is of the shoe and segment type toggle mechanism. In these figures the rotation of the cam about the point I5 is counter-clockwise, tending to cause the guide l3 to be thrown against the cone of yarn with an impact as ,the traverse arm It changes direction at the end of the stroke. To prevent this from occurring, the dog mechanism now in use consists of a shoe 2| which rides in a segment 22.
The spring 23 exerts a force against a lever 24 which is rigidly connected to the dog rod 25, thereby pressing the shoe 2| up into segment 22, thus tending to lock the traverse back Hi from moving in a counter-clockwise direction. This locking force, which is a force exerted on the traverse back It tending to rotate it counterclockwise about the pivot I5, is made up of weights 26 acting through a system of levers, not shown, and the force exerted by the counterclockwise rotation of the cam traversing the traverse arm back and forth along the side of the cam, all of which is well known to those in the sirable that the tension should gradually decrease as the cone builds up so that the final tension .is about one-half the starting tension.
.Along with 'the'tension, the back pressure exerted by the button guide on the cone must be such that it will tend to smooth out the surface making a straight sided cone.
The quality of a cone yarn is, also, dependent upon the hardness or density as determined by the spring 23 is compressed on installing and upon how well the shoe 2| fits in the segment 22. Therefore, this braking action must be taken into consideration when determining the total back pressure against the cone. Due to this force, a great difference in the back pressure acting on the individual spindles of the machine has been encountered. For example, with one machine out of 18 spindles measured, the variation of back pressure was from ounces to 25 ounces. This 15-ounce variation represents a total of 11 points of density. This variation gives considerable trouble at the speeds at which the yarn is run so that normal cone density is around 75 to 80 durometers. Therefore, only a small increase in back pressure is allowed in order to hold the cones of yarnwithin the density limits required.
Another difliculty which has been encountered is the short life of present dog shoe which necessitates constant readjustment. The present dog mechanism does not, therefore, prevent defective cones. In addition, the present dog is now installed on the inside of the machine which makes it very unhandy to make adjustments.
It has been found that the quality of the cone yarn may be greatly improved by eliminating the braking action present in the dog mechanism now in use and described above. This has been accomplished by an entirely new dog mechanism which will be described in connection with Figs. 3 and 4 of the drawings. A steel plate is mounted out from the front 3| of the machine by means of two cylindrical spacers 32 and 33 to bring the plate 30 in position below the yarn cone, as shown in Fig. 4; A connecting link 34 has the upper end rigidly connected to a rod 35 depending from and secured to the traverse back It to thus rigidly connect the latter to the link 34. The lower end 38 of the link 34 is bifurcated and is pivoted on a pin 31 carried by the plate 30-. The upper surface of the plate is inclined, as shown at 38 in Fig. 3, and slidably supports a wedge-shaped member 39, the upper inclined surface 40 of which is adapted to engage the surface 4| formed at the base of bifurcated ends 36 to wedge the member 39 between the surfaces 38 and 4| for a purpose to be later described. The wedge member 39 may slide downwardly along the surface 38 due to its own weight, but it is preferred to move the wedge member 39 positively by means of a weight 42 connected to-the wedge 39 by means of a cord'43 which passes over the lower edge 44 of the plate 30 to permit the weight to hang vertically, as shown in Fig. 3. The weight 4| thus tends to move the wedge member 39 downwardly and to the right along the inclined surface 38 of the plate 30 to retain the wedge in wedging relation between the surfaces 38 and 4|, as is apparent.
In practice, the dog mechanism operates as follows: The yarn II is wound on the paper tube II which revolves in a clockwise direction by a suitable driving means, not shown. The yarn II is guided onto the cone by the reciprocating button guide 3 which is connected by means of a traverse arm H to a cam, not shown, which revolves about the center line of the pin 31. The traverse arm I4 is mounted in a slot, not shown, in the traverse back It which, with the link 34, is pivoted on the plate 39 for movement as a unit about the pin 31 in such a manner that as the yarn cone builds up during the winding operation, the traverse back It and link 34 move in a clockwise direction about the pin 3'! leaving a small space between the upper surface 38 of the plate 30 and the surface 4| of the link 34. As this space increases, through the clockwise movement of the back l6 and the link 34, the weight 42 moves the wedge member 39 downwardly along the surface 38 of the plate 30 to bring the surface 49 of the wedge 39 into engagement with the surface 4| of the link 34 to wedge the member 39 between the surfaces 38 and 4|, as is apparent, to prevent the traverse back Hi from bouncing backwards in a counter-clockwise direction, the advantages of which will be readily apparent to those in the art.
This dog mechanism has proved to be positive in its action and to be self-locking to prevent the counter-clockwise movement of the back l6 and the link 34 about the pivot pin 31. As the back l6 and link 34 are fixed together and move as a unit about the pin 31, these members constitute, in efiect, a single unit so that the traverse back may be broadly considered as pivoted on the plate 39 and movable about the pin 31.
By the use of this new form of dog mechanism, the machine efliciency has been greatly increased and the yarn quality has been improved. However, the factor which is considered the most important is the elimination of the braking action and the traverse back as it moves in a clockwise direction. Thus the total back pressure exerted on the cone of yarn may be reduced considerably from that formerly obtained with prior dog mechanisms. It has been found that a minimum back pressure may now be obtained as low as 2 ounces with a variation of 1 ounce, whereas the minimum practical setting of back pressure on the present dog mechanism shown in Figs. 1 and 2\ is about 14 ounces, the actual back pressure running from 10 to 25 ounces, or a variation of 15 ounces. As a result of this improvement, it is impossible to lower the density of the cone to fall within the established standard range. This improvement has also made it possible to practically eliminate certain winding defects, such as bulged cones due to too much back pressure, and soft rings and loops due to a variation in the back pressure while the cone is being wound.
The apparatus of the present invention thus provides a mechanism by which the motion of the traverse back is not restrained in one direction of movement by a force which is necessary to enable the mechanism to look when turned in the opposite direction. While such a dog mechanism is shown in connection with a cone winding machine, it is adaptable to any mechanism or machine where unrestrained movement is required in one direction combined with a positive locking stop in the opposite direction. This new and improved dog mechanism also eliminates the braking action of the traverse back as it moves in a clockwise direction, and also removes the back pressure of the button guide so as to insure straight cones without dips in the sides thereof.
of ways.
