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 ...
