Warren, Ohio, assignors to The Wean Engi neering Company, Incorporated, Warren, Ohio, a corporation of Ohio Application November 24, 1936, Serial No. 112,551 10 Claims. (Cl. 242-78) 'I‘his invention relates to an apparatus for coil- , ing and, in particular, to a device for ceiling strip material in long lengths under substantial ten sion.` 5 Coiling reels as heretofore constructed have generally consisted of a collapsible mandrel Vmounted on a mandrel acting by any suitable l() tial tension on suitable supporting housing, the as a cantilever, and being driven power means to exert a substan the material being coiled as it issues from a rolling mill, for example. Ceiling lreels of this type are satisfactory for smaller widths of strip. When widths of the order of 40" or above are to be handled, however, the '15 defiection of the free end of the `mandrel is such i that the tension applied to the strip by the coil ing reel is not uniform across the width of the strip. Since the tension controls the amount of reduction which is effected in the mill, the strip 20 is thus of non-uniform thickness. When it is sheared to length and further processed, this non-uniformity introduces a longitudinal camber into the lengths. n Our invention overcomes the aforementioned objections to the ceiling devices as previously constructed, and provides a device capable of ceiling strip of any width, under the desired ten sion, without objectionable deflection of the man drei. In accordance with our invention, We pro Fig. 4 is a sectional view along the line IV--IV of Fig. 3 with parts omitted; and 0 10 tive thereto. Guides l5 extend downwardly from the seat through suitable bearings in the base. The vertical adjustment of the seat is accom plished by a screw i6 threaded through a nut in 16 the base. The motor I'l drives the nut through suitable gearing (not shown). The mandrels il) and ll and their supports are identical except for minor details. Each mandrel comprises a plurality of segments i8 dovetailed to an arbor I9 by flanges lsb, as best shown in Figs. 3 and d. The several segments it have inter iìtting, overlapping projections or teeth lßa whereby a substantially smooth circumference is presented whether the segments are collapsed or 25 expanded. Cooperating inclined surfaces t@ and 2l on the segments and arbor cause the segments to be expanded on movement of the arbor axially 3d vide a pair of axially alined mandrels, at least ` thereof. one of which is movable toward the other. Each mandrel has adjacent its end cooperating inter iitting means effective when the mandrels are abutted, to increase the resistance thereof to de 35 ñection under the coiiing load. Each mandrel is provided with an anchor slot for receiving the leading end of a length to be coiled, and we provide means for driving the mandrels such that they are always maintained in a predeter 40 mined angular relation so that the anchor slots in the two mandrels are always in line. We also ' Fig. 5 is a diagram of the driving gears. Referring now in detail to the drawings, our coiling reel comprises essentially a pair of axially alined mandrels I0 and I l, mounted for advance ment into abutting engagement and retraction, and a lifting saddle l2 there below adapted to receive and hold a coil when the mandrels are withdrawn. The saddle comprises a seat I3 sup ported on the base Hl for vertical movement rela The dovetailed relation between the segments and the inclined portions of the arbor 30 causes collapsing movement of the segments on reverse movement of the arbor relative thereto. A stop ring 2id limits axial movement of the arbor i9 relative to the segments it. An anchor slot 22 is formed in one of the seg ments it for receiving the leading end of a length of strip to be coiled. The means supporting the mandrel for rota tion and axial reciprocation comprises a ñxed housing 23 secured to a base 2d resting on any suitable foundation 25.> The housing 23 is cored, provide means of novel construction for advanc machined, and provided with bearings 26 at each ing and retracting the mandrels. end whereby to receive and support for rotation, Further details of the invention will become ap parent in the course of the following description, a cylinder 2l. The housing 23 includes also a gear case 28. A driving gear 29 is disposed on referring to the accompanying drawings. In thev the cylinder 2l within the case 28. drawings, A piston 30 is slidable axially in the cylinder 2l Fig. 1 is a plan view of a coiling reel in accord but rotates therewith by reason of a feather key ance with 'our invention; Fig. 2 is a side elevation thereof partly broken 3l'. The piston has spaced end walls 32 and 433, each having bearing bushings 32a and 33a spac away; ing them from the bore of the cylinder 2l. 'I'he Fig. 3 is a partial sectional view to enlarged end walls 32 and 33 are connected by a cylindri scale on the line II-III of Fig. 1; cal wall 34 and radial webs 85. Figure 3A is a partial sectional view taken 'I‘he cylindrical wall 34 of the piston 30 is cored along the line IIIA-_IIIA of Figure 3; and and machined to receive the inner end of the 2,117,640 arbor I9 which is secured therein by screws 33. The arbor and the segments carried thereby are thus caused to rotate with the piston 30 and the cylinder 21 when the gear 29 is driven. The a definite clearance must be provided between the lower edge of the plate 60 and the segments I9. Cylindrical guides 61 are mounted on the hous ing 23 and are adapted to receive slide rods ex inner ends of the segments I3 have outwardly ‘ tending rearwardly from the yoke 53. These extending flanges 31 which fit loosely between the end wall 33 of the piston 30, and a stop ring 33 secured to the inner end of the cylinder 21. A cylinder 39 is positioned within a bore 10 through the arbor I9, bearings 40 and 4I per mitting rotation of the arbor about the cylinder. rods prevent rotation of the cylinder 39 as the cylinder 21 turns. After retraction of the mandrel, it may again be advanced to its illustrated position by deliver ing fluid under pressure through the pipe 53. The 10 cylinder 39 is then forced to the right and carries The inner end of the cylinder 39 is closed by a head 42 secured thereto in any desired manner. A stub shaft 43 extends inwardly from the head 42, being secured therein by a lock nut 44. The inner end of the head 42 is seated in a bearing 4Ia. A tapering stud member 45 is rotatably mounted at the inner end of the shaft 43 on a bearing 46. The stud member 45 cooperates with a socket member 41 similarly mounted on the mandrel II. The segments I8 of the man drels have conical abutting surfaces 48. A piston 49 is supported in fixed p_osition within the cylinder 39 on a hollow piston rod 50, the outer end of which is anchored to a suitable abut ment 5I (Fig. 1). A radial hole 52 in the rod 59 permits fluid to be supplied through the latter to the space on the left-hand side of the piston 49. A pipe 53 extending through the rod 50 com 30 .municates with the space on the right-hand side of the piston 49 through a port 54 in the latter. The left-hand end of the cylinder 39 is closed by a head 55 which may conveniently be bolted by bolts 55a to a yoke 56 welded or otherwise se cured to the cylinder 39. A packing gland closes the space between the head 55 and the rod 50. When fluid under pressure is_ supplied through the rod 50 and the hole 52,` the cylinder 39 moves 40 to the left inasmuch as the piston 49 is held sta tionary. Leftward movement of the cylinder 39 is caused by the pressure of the fluid admitted thereto acting on thepiston 49 and the cylinder head 55. The stub shaft :43, being secured to the ` cylinder head 42, moves with the _cylinder 39 and withdraws the stud member 45,4 andv with it the arbor I9 and the piston. 39. The segments I3, however, do not initially m'ove with the arbor I9. Spring-pressed plungers 53 mounted in thev end 50 wall 32 of the piston 30 and extendihgthrough holes in the other end wall 33 into‘eng'agement with the segment flanges 31,-hold t‘he segments in their illustrated positions until the stop ring 2Ia engages the ends’of the inclined surfaces 20. the mandrel I0 with it until it abuts the mandrel II in the manner indicated in Fig. 3. After the engagement of the segment flanges 31 with the stop ring 39, continued movement of the piston 30 expands the segments I8 and restores the plungers 53 to their illustrated position. The gears -29 of the two mandrels are driven by pinions 68a, in housings 63. The pinions are con nected by a cross shaft 39 which is, in turn, driven by a pinion 10a enclosed in a. housing 10. This pinion is driven by a motor 1I through a hydraulic drive including a pump 12 and motor 13 coupled to the shaft on which the pinion is carried. This drive permanently ties the two 25 mandrels together, and always maintains them in predetermined angular relation, ensuring that the anchor slots in the two mandrels will always be in line. If it is desired to handle large coils, over-size 30 segments, indicated in chain lines at 14, may be bolted to the segments I8. In this event, a ñller block 15 is removed to permit the over-size seg ments to be keyed to the segments I8. It will be clear from the foregoing description that when the mandrels I0 and II are advanced into abutting engagement, as shown in Fig. 3, the cooperation of the conical surfaces 48 there of and the interfltting relation of the stud mem ber 45 with the socket member 41 will provide a substantially continuous beam member to with stand the load imposed thereon by the coiling operation. The resistance of the two mandrels lto deflection when so united, is naturally greater than the sum of the individual .esistances of two 45 similar mandrels supported independently as cantilevers. The shape of the cooperating parts of the two mandrels is such that a proper en gagement thereof on advancement of the man drels is assured at all times. The initial with 50 drawal of the mandrels, however, effects an im mediate separation thereof. The coiling apparatus described above, because of its increased rigidity and resistance to deflec tion, is capable of handling coils of wide strip 55 This initial movement _of the. arbor I9, while the ’ without causing an objectionable lack of uni segments are maintained. against axial move formity in the tension of the material being ment, causes the latterto'be l,collapsed for easy coiled, across the width thereof. A more uniform withdrawal from a coil 59 'surrounding the man drel. Thereafter, the segments I8 move with the 60 cylinder 39. and the construction‘is such that the mandrel I9 may be entirely withdrawn from the - coil. A stripper plate 60 is', slidably mounted on the housing 23 by guide rods 6I traversing bearings 32. A cylinder 63 carried on the housing is pro vided with a piston 64 having a rod 65 connected to the plate 60. The stripper plate may be used to hold the coil against the thrust applied to the arbor, to withdraw the mandrel from the coil or product is thus obtained. and all diiiiculties with cambering of sheared lengths in subsequent 60 processing is avoided. While we have illustrated and described here in but a preferred embodiment of the invention, it will be understood that changes in the con struction disclosed may be made Within the spirit 65 of the invention and the scope of the appended claims. , We claim; 1.
