Claims. (Cl. 242-130) This invention relates to takeup stands for winding filaments onto reels, and more particularly to takeup stands for supporting a plurality of reels in a row while I winding filaments thereon.

In some large scale manufacturing operations performed on filaments,'such as the electroforming of copper-clad steel wires, a large'nurnber of reels may be mounted rotatably on takeup stands arranged in one or more rows. Each of said takeup stands generally includes a pair of separate arbors mounted at opposite ends of each reel in the row. Where manufacturing-floor space is limited or at a premium, this arrangement may not be satisfactory. In some cases an excessive amount of floor space may be occupied, and in other cases it may not be possible to accommodate the desired number of reels per row required to attain maximum efficiency. Itwould be advantageous to reduce the space occupied by the arbors in each takeup stand, but this has not been possible with the takeup stands known heretofore.

An object of this invention is to provide new and improved takeup stands for winding filaments onto reels.

Another object of the invention is to conserve manufacturing floor space when a plurality of such takeup stands are mounted in a row.

Apparatus illustrating certain features of the invention may include a pair of rotatable members facing in opposite directions and designed to engage and support the hubs of a pair of adjacent reels in a row thereof, and

means for effecting relative movement between the members along their longitudinal axes.

A complete understanding of the invention may be obtained from the following detailed description of apparatus forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which:

Fig. 1 is a plan view of a row of reels supported on apparatus embodying the invention;

Fig. 2 is an enlarged, vertical section taken along line 2-2 of Fig. 1, and

Fig. 3 is an enlarged, vertical section taken along line 3-3 of Fig. 1.

In accordance with the invention, when a plurality of takeup stands are mounted side by side in a row, the space occupied by the stands is reduced by substituting a single stand embodying the invention for the two separate stands formerly employed between each pair of adjacent reels in the row. As shown in Fig. l, a plurality of reels -10 are positioned side by side in a row while taking up a plurality of wires 12-12. The reels 10-10 are supported rotatably on their hubs 13-13 by aplurality of dual reel-engaging stands 14-14, one of which is mounted between each pair of adjacent reels in the row.

Referring to Fig. 3, each of the stands 14-14 includes a frustoconical, longitudinally movable, reel-engaging member 16 mounted on one side of the stand, and a frustoconical, longitudinally fixed, reel-engaging member 18 positioned on the other side of the stand. The frustoconical members 16 and 18 function as the reelengaging portions of arbors, which face in opposite diice rections away from the stand and support the reels 10-10 on opposite sides thereof. The movable member 16 is freely rotatable on a plurality of ball bearings 20-20 mounted at one end of a piston 22 having a piston head 24 secured at the other'end thereof. The piston 22 is reciprocable, through one end of a cylinder 26 in which the piston head 24 is slidably mounted, and the reciprocation of the piston 22 is fluid actuated. One

end of the cylinder 26 is connected to a double actingfour way valve 28 by means of an orifice 30 leading to a pipe 32. At the opposite end of the cylinder 26 an orifice 33 communicates with a channel 34 which extends through the wall of the cylinder for the entire length thereof to a second pipe 35, which is also connected to the four way valve 28. Another pipe 36 (Fig. 1) provides the valve 28 witha supply of a fluid medium, such as air under 7 pressure, and an exhaust port 37 valve to the atmosphere. I j j V A see-saw type foot treadle 38 controls the operation of the four way valve 23'. By stepping on the proper end (Fig. 3) leads from the of the foot treadle 38, compressed air is admitted to one end of the cylinder 26 and simultaneously exhausted from the other end thereof. This action slides the piston head 24- from one end tothe other of the cylinder 26, thereby shifting the movable reel-engaging member 16 between a reel-engaging position and a reel-disengaging position.

In Fig. 3 full lines are used to show the member 16 in its reel-disengaging or retracted position, and phantom lines are used to show it in its reel-engaging or advanced position. One of the reels 10-10 is shown in phantom lines in Fig. 3, with the hub 13 at the left hand end thereof engaged and supported by the movable member 16 when this member is in its advanced position to the right. The right hand end of this reel is supported by a longitudinally fixed member which is identical with the member 1% shown in Fig. 3, and is mounted on the adjacent one of the drive shaft 40, and it engages a ring 46 on the stand 14. A spring 48 normally urges an arr'n50 to turn about a 'pivot 52,. thereby bringing a jockey roller 54 to bear against the belt 44 at a point intermediate the pulley and the ring 46. This action places the bell 44under tension, and causes power to be transmitted from the drive shaft 40 to the ring 46. As shown in Fig. 3, the

ring 46 is provided with-a radial flange 56 which is con nected directly to a tubular shank 58 of the longitudinally fixed reel-engaging member 18, by means of a plurality of bolts 60-60. Thus, the member 18 and the reel 18 supported thereon rotate when the belt 44 is placed under tension by the action of the jockey roller 54 riding there- The rotation of the reel 10 may be halted byreleasing the tension applied to the belt 44 by the jockey roller 54, and at the same time applying a brake 62 againstthe ring 46.. A pivoted link 63 connects the brake 62 to a lever 64 having a handle 66 on the upper end thereof to enable it to be grasped by the operator. The lower end of the lever 64 is joined pivotally to the arm 50, so that upward movement of the lever 64 pivots the arm 50 against the action of the spring 48 and moves the roller 54 away from the belt 44. This action puts sufiicient slack in the belt 44 to prevent the drive shaft 40 from transmitting power to the ring 46. A notch68 on the lever 64 engages a lug 70 when the brake 62 is applied, and this holds'the brake be disengaged readily brake.

The lug 70 is mounted on a vertical frame 72 which rises from a base 74 or each stand 14. The frame 72 forms a transverse wall between the reels 10 on the opposite sides of each of the stands 1414, as shown in Figs. 1 and 2. An annular housing 76 (Fig. 3) is mounted 'in and eX'tends transversely throu h the frame 72. A plurality of ball bearings 78-78 and a plurality of selflubricating bearings 7979 permit the rotation of the tubular shank 58 of the member 18 Within the housing 76. The cylinder 26 is mounted on a plurality of ball bearings 808il and a plurality of self-lubricating bearings 81-81 Within the shank 58. By virtue 'of the sup port incidently obtained from the pipes 32 and which rise thereto from the valve 28 on'the base 74, the position of the "cylinder 26 remains fixed While the shank '58 of the member 18 is free to rotate thereon.

It is evident that the reels 10-10 are mounted independently, so that when one of the reels becomes full it may be removed and replaced by an empty reel without interferring with the takeup operations being performed on any of the other reels in the row. Each of the reels 10-40 is supported and rotated -by the joint action of a longitudinally fixed arbor having a reel-engaging member corresponding to the member 18 on one of the stands 14-l4, and by a cooperating longitudinally movable member corresponding to the member 1'6 on another, adjacent one of the stands. Of course, the frustoconical members 16 and 13 on all of the stands 1414 are aligned so that they support the row of the reels 10-10 in a straight line. The frustoconical shape of the reel-engaging members 16 and 18 matches the shape of the hubs 1313 of the reels 10-10, thereby enabling these members to center and elevate a reel placed between them. When the movable member 16 is shifted towards the longitudinally fixed member 18, these members enter the hub 13 of a reel positioned between them, and raise the reel olf the floor by a camming action.

In order to stop and remove one of the reels 1010 from between an adjacent pair of the stands 1414, on the stand carrying the driving member corresponding to the member 18 the brake 62 is applied to stop the rotation of the test, and on the cooperating adjacent stand the foot treadle 38 is operated to retract the movable member corresponding to the member 16. This releases the full reeL'and drops it to the floor so that it may be rolled out of the row. The operator then substitutes an empty reel in its place, and advances the member 16 towards the cooperating longitudinally fixed member 18, thereby elevati'ng this reel above the floor and supporting it in position for rotation to'take up one of the wires 1212 there- The wires 1212 are distributed evenly upon the reels 1G-10 by means of a plurality of traversing guides 82-82, which are mounted upon a traverse shaft 84 at spaced points corresponding to the positions of each of the reels in the row thereof. The traverse shaft 84 moves the traversing guides '8282 in unison alternately back and forth across the reels 1i-10 from one end to the other thereof. Each of the traversing guides 8282 includes a pair of spaced guide rolls 8686 between which one of the wires 1212 passes. A control mechanism 88 motivates the reciprocation of the traverse shaft 84 and automatically reverses its direction of movement at the proper intervals. Distribution units like the traversing guides 82-432 are well known in the art of winding wire. Further details of the construction and operation of such guides are disclosed in my copending application Serial No. 308,132, filed September 5, 1952, entitled Strand- Advancing Apparatus.

'By the use of dual reel-engaging stands embodying the invention inbetween each pair of adjacent reels in a row thereof as well as at opposite ends of the row, the number of such standsrequired to support the entire row may be reduced to only one more stand than the number of reels in the row. Or, the number of such stands needed may be further reduced to one stand less than the number of reels in the row, by substituting at the extreme opposite ends of the row stands having only a single reel-engaging member. In the latter case, as shown in Fig. l the extreme right hand end of the row is provided with a freely rotatable, longitudinally movable arbor 90, which is re ciprocable by an air cylinder 92 operated by a foot treadle 94. The opposite end of this row is provided with a power driven, longitudinally fixed type of arbor (not shown). Thus, the use of 'takeup stands embodying the invention efiectively conserves manufacturing floor space.

Although only a single embodiment of the invention is illustrated and described herein, numerous other embodiments may be devised to meet special requirements, without departing from the spirit and scope of the invention.
