Problems solved by technology

These mechanical linkages add considerable inertia to the device, thereby slowing the spooling process.
Previous devices have not performed direction reversal of the pivotally mounted guide, other than end of stroke mechanical linkage adjustments.
Previous traversing components, for the most part, have not addressed the tension fluctuations that is common to traversing.

example

[0034] Let:

[0035] Rsi=-4 Tw=8 L=0.2 Cs=640 Cp=480 Tp=1800 r=10.75 5 Cr =Cs Cp Cr = 1.333

[0036] Fsi=Tw+Rsi Fsi=4 6 Da ( Y ) = a tan ( Yr 2 - Y 2 ) ( Tp 2 )

[0037] Y=Fsi-(L.times.Cr) Y=3.733

[0038] Da(Y)=101.607

[0039] If the rear stop (Rsi) is entered as -4 inches and the traverse width is 8 inches, the front stop (Fsi) position is calculated as 4 inches.

[0040] If the winding arbor count (Cs) is 640 steps and the arbor encoder PPR is 480, the arbor revolution count (Cr) is 1.333.

[0041] The desired traverse motion from the front stop is (Cr*L)=0.267 inches. This value (Y) is 3.733 inches from the origin.

[0042] When the traverse reaches the rear stop position, the logic commands the motor to a position that satisfies the equation Y=Rsi+(L*Cr), that is, the linear position is the rear stop in inches+(lay*arbor revs).

[0043] When the traverse reaches (Rsi) the accumulative count of (C1) is set to zero, the rotation of the traverse motor is reversed, and the equation Dti=Rsi+(L*Cr) is applied...

Abstract

A linear traverse mechanism for guiding the spooling of a flexible linear product at high speed, made possible by reducing the inertial load of the mechanism while reducing the angular deflection of the filament. The mechanism includes a pivotally mounted guide arm controlled by an electric motor having precision indexing ratio characteristics to compensate for linear error. In one embodiment, the linear product is fed through a guiding means carried by said traverse arm to be discharged adjacent a receiving spool.

Description

RELATED INVENTION[0001] This application is a continuation-in-part of my copending application, Ser. No. 09 / 427,443 filed Oct. 27, 1999.[0002] This invention relates generally to the field of spooling a flexible linear product such as thread, wire, cable, hose, and the like, and more particularly to an improved guiding means which moves in a plane parallel to that of the spool which forms progressive layers of product as the spool coil rotates, while minimizing tension fluctuation that typically accompanies high speed traversing.[0003] Traverse guiding means are well known in the art, and have included a pivotally mounted guide having an orificed free end through which the product passes, as well as mechanical driving means, including a driven disc, and linkage communicating with a point on the guide.DESCRIPTION OF THE PRIOR ART[0004] Previous pendulum type devices have been employed to move a flexible product in a linear motion while the product is being wound onto a package, such ...
