7 Claims.
'I'he present invention relates to machines for winding yarn, thread or other filaments, and more particularly relates to improvements in devices for controlling the density and size of the packages wound by such machines.
The present invention is adapted to be practiced in connection with winding machines in which a thread is caused to reciprocate while feeding onto a package through means carried by a support known as a back, the package being wound on a rotatable package support, the back and the support being relatively movable and being adapted to be urged into separated position by the action of gravity or other suitable means. The thread guide is maintained either at a predetermined light pressure in contact with, or barely out of contact with, the surface of the package being wound, whereby the density and size of the package may be accurately controlled. To accomplish this, the package support and the back are locked against relative separating movements by suitable means which are adapted to be released intermittently as the package grows in size under the control of means contacting the package such as a feeler roll. This feeler roll is adapted to be rotated upon frictional engagement with the rotating package being wound to effect actuation of means controlling the release of the locking means.
The present invention aims to provide improved control means for operatively connecting the package contacting means and the locking means, whereby operation of the contacting means by the package renders the locking means ineffective and thereby permits separation of the back and the package support. More specifically, the present invention aims to provide nonelectrical control means for accomplishing the foregoing, thus eliminating the necessity of electrical wiring and contending with different electrical service currents in various localities and thereby making the winding machines equipped with devices embodying the invention adaptable for use anywhere. y
An object of the present invention is to provide simplified means for controlling the separation of the back and package support of a winding machine of the character indicated.
Another object is to provide mechanica-1 means for controlling the separation of the back and package support, which are easily installed.
A further object is to provide improvements oi' the foregoing character which are positive in operation, rugged in construction, are not likely to get out of order, and do not require supervision or repair.
Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.
A preferred embodiment of the invention has been chosen for purposes of illustration and description, and is shown in the accompanying drawing, forming a part of the specification, wherein:
Figure 1 is a fragmentary perspective view of the back and package support portion of a winding machine embodying the present invention with the back retardlng means broken away.
Figure 2 is a fragmentarv side elevational view, illustrating in detail the means for retarding separation of the back and package with the cover removed therefrom.
Figure 3 is a front elevational view of the retarding means shown in Figure 2 illustrating details thereof.
Figure 4 is an enlarged fragmentary perspective view of latch control means.
The present invention may be `embodied in any desired winding machine of commercial construction insofar as the elements for supporting and rotating the winding spindle and for imparting traversing movement to the thread guide are concerned. Accordingly, in Figure 1 there is shown only one of the upright side frames I0 of such a winding machine. A horizontal spind'le II is supported in this frame by suitable journal boxes and is arranged to be rotated at high speed. The spindle has a ange at its inner end and a removable collar at its outer end between which is clamped a cop or bobbin on which the thread package I4 is to be wound.
A back carrying the thread guide is supported to rock freely about the axis of a shaft I5 projecting outwardly from the side frame i0, whereby the package supporting spindle Il and the back are arranged for relative separating movement. The back includes an upwardly extending arm I6 carrying a transversely extending frame I1 provided with a bearing for a slide I8 from which extends an upright arm I9 carrying a thread guide 29. The slide I8 is reciprocated at `high speed by a cam mechanism (not shown) to traverse the thread guide 20 back and forth in a longitudinal path parallel to the surface of the thread package I4.
In the upper portion of the frame I1 an elongated yoke 2I is secured having forwardly extending arms at each end between which is journalled a long feeler roll 22. This roll is pivoted for rotation or pivotal movement about its longitudinal axis and is adapted to engage the rotating package I4 being wound as it grows in size, whereby the roll is turned about its pivot. Such turning of the roll is utilized to control the separation of the back and package support in response to the growth of the package as will appear hereinafter.
Separation of back and package normally is prevented or governed by retarding means herein illustrated (Figures 2 and 3) as an escapement mechanism which is secured to the side frame I0 by a bracket 26.
The escapement mechanism comprises a spaced apart pair of side frames 21 and 28 having a rotatable hollow shaft 29 journalled therein having its axis in alignment with the axis of the shaft I5. The inner end of the shaft extends beyond the side frame 26 and has an arm 30 secured thereto which has a slot 3I at its free end for receiving a stud 32 on an extension 34 of the arm I6 (Figures 1 and 2), whereby the back and escapement mechanism are operatively connected.
A gear 35 is mounted for rotation on the shaft 29 between the side frames 21 and 28 and is connected for rotation with the shaft 29 by clutch means comprising a member 36 having a face frictionally engaging one side of the gear 35 and a second member 31 having a face fnictionally engaging the other side of the gear 35. In this manner the back can be moved towards and away from the package by applying a force overcoming the clutch friction without imparting rotative movement to the gear 35 through the extension 34, the arm and the shaft 29.
The clutch members 36 and 31 are mounted for rotation with the shaft 29 and are connected for rotation with each other by an extension 39 on the member 36'having a slot 48 and an extension 4I on the member 31 having a lateral projection 42 extending into the slot 40. The clutch members are urged to rotate the shaft 29 in' a direction to assist moving the back away from the package through the arm 30 and extension 34 by means of a spring 44 coiled about the shaft 29 and having one end secured to the side Y frame 28 and having its other end secured to the clutch member 31.
Rotation of the gear normally is prevented by an escapement pawl 45 engaging a star wheel 46 which is connected to the gear 35 by a train of gears 43. 49, 50, 5| and 52 rotatably mounted on the side frames of the escapement mechanism 25. 4
The pawl 45 is mounted for oscillating movement to permit the same to move out of and into engagement with the star wheel 46. This is accomplished by a rod 54 extending through the hollow shaft 29 having the pawl 45 secured thereto at one end thereof and having a latch segment 55 secured thereto at the other end thereof.
A device is provided to take up the back-lash of the gear train when the back is pushed against the package which back-lash allows the back to fall away from the package by the amount of backlash. This device comprises a rotatable rubber covered wheel 56 and a spring-like arm 51 having the wheel 56 mounted on one end thereof and having its other end secured to the cover of the retarding means (Figure 3). When the wheel 56 is manually pushed inwardly and turned counterclockwise it engages the star wheel and turns it, which rotates the gear train sufficiently to move the back the amount that it had fallen away.
The segment 55 has a series of detents adapted to be engaged by a latch element 60 (Figures 1, 2 and 4) on one end of an arm 6I pivoted at its other end on a bracket 62 secured Vto the extension 34 of the back. yThe latch element shown herein is formed of spring steel to absorb shock upon engagement of the detents and is mounted to jump out of engagement to allow the back to be moved manually. This is accomplished by forming a pair of recesses 64 on the underside of the arm 6I which are spaced apart transversely by an opening 65. The latch element has upwardly facing edge portions 66 seated in the recesses and has a portion 61 of reduced width extending through the opening 65. The
I portion 61 has one end of a spring 69, under tension, secured thereto and the other end of the spring is secured to a yoke 10 mounted on the arm 6 I.
The latch element is adapted to bemoved out of the detents of the segment 55 upon lifting the arm 6I. The latter is accomplished by linkage means mechanically connecting the feeler roll 22 and the arm 6I. As shown herein such linkage means may comprise a link 1I such as a wire-like rod having one end secured to the arm 6I and a chain 12 or the like having one end connected to the other end of the link 1I and having its other end connected to the feeler roll in a manner to exert a pull on the link upon turning of the feeler roll, whereby the feeler roll causes the latch element to be lifted out of the detents of segment 55.
In order to control thedensity of the package v being wound, the friction between the package and the feeler roll necessary to effect turning of the latter by the former is varied by increasing or ldecreasing the force on the chain opposing turning of the roll. This is vaccomplished by mounting removable weights 14 on a pin 15 secured to the arm 6I. By increasing the number of weights the force opposing the rotation ofthe roll is increased and likewise the friction necessary to eect rotation of the roll by the package is increased, whereby the roll exerts greater 'pressure on the package to produce a more densely wound package. The opposite effect is accomplished by reducing the number of weights.
In operation, when the thread package is being wound, the back is moved towards the spindle II by hand with suiiicient force to overcome the friction between the clutch members 36 and 31 to position the feeler roll 22 on the surface of the package I4 or the cop on which the package is to be wound. As the package grows in size the friction contact between the feeler roll and package gradually increases until the package is then wound on the feeler roll and exerts a pull which is effective through the link 1| to raise the latch arm 6I to thereby cause the latch element 60 to release the latch segment 55.
When the latch segment is released, the rod 54 carrying the escapement pawl 45 is free to oscillate, thus releasing the pawl to enable the star wheel 46 to rotate step by step under the actuation of the spring 44. The back is then free to move away from the spindle under the influence of gravity and the spring 44, but the back moves away very slowly due to the train of gears 4B, 49, 50, 5| and 52 between the star wheel and the back.
As the back and package separate, the feeler roll is moved out of contact with the surface of the thread package or only lightly contacts the package to permit the roll to return to its initial position under the influence of the weight of the latch arm 6l connected thereto by the link 1| and chain 12. The latch element then enters one of the detents of the latch segment 55 to lock the rod 54 carrying the pawl, whereby the pawl prevents further movement of the star Wheel. When the package again grows in size these operations are repeated.
From the foregoing description it will be seen that the present invention provides an improved arrangement for periodically and intermittently locking the back and releasing the back for separation with respect to the package. Mechanical linkage between the feeler roll and the locking means eliminates electrical connections. The device is rugged in construction and can readily withstand any rough usage to which it may be subjected.
As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in any limiting sense.
The escapement mechanism and the latch therefor, illustrated and described herein, constitute the subject matter of copending application Serial Number 717,188 filed December 19, 1946.
