8 Claims. 1
This invention relates to improvements in blockers and coil handling devices particularly adapted for use in conjunction with a'slitter of the type which longitudinally slits a coil of metal into a plurality of strips.
Heretofore the recoiling of slit metal has been attained by securing all of the ends of the strips to a common spool or block with circular spacers between the strips. This method necessitates the hooking of each individual strip into a slot in the block and placing the separate spacers between the strips, and after the'strips are coiled, the spacers and coils must be removed singly while holding each coil by hand until banded. to prevent its springing open. This takes considerable time and rehandling of spacers. Also, in slitting strip metal, the burrs along the edges of the metal will extend in opposite directions from each adjacent strip, so the burrs of one strip will extend upwardly as it comes from the slitter and the burrs of the next strip will extend downwardly. When the strip is coiled it is desirable that all of the burrs extend either towards the inside or outside of the coils. This is not possible where a single block is used for recoiling.
Individual blocks for each strip have been used in an attempt to overcome these difflcultles, but
1 time to time as the following specification prothe accompanying Figure 3 is an enlarged transverse sectional view looking in a direction towardsthe coil blockers and showing certaindetails of the coil spacing and transferring mechanism;
these individual blocks have not remedied the sit nation to any great extent.
The device of our invention has as its principal objects to overcome these difllcultiesby providing a novel and simplified form of block and guide arrangement, so arranged that the strips and blocks are convenient to'the operator and can be inserted and secured to the strip coiling block with a minimum amount of effort and be wound in the desired direction, together with a means for removing the coils as a. group and keeping them in this relation until properly handed and ready for storage or further treatment.
' A more specific object of our invention is to provide a novel form of blocker and coil handlin device adapted to receive and simultaneously coil a plurality of strips of metal as they come from a slitter, which includes a pair of coiling blocks arranged to simultaneously coil alternate strips oi metal and permit the coils to be removed from the ends of the coiling blocks, together with an Figure 4 is a transverse sectional view drawn to asmaller-v scale than Figure 3 and showing the coil push-01f mechanism in a fully extended position; x

In the embodiment of my invention illustrated in the drawing, a blocker generally indicated by reference character I is provided. Said blocker includes two vertically spaced power driven collapsible coil blocks II, II, adapted to simultaneously coil a plurality of strips of metal as they come from a slitter generally indicated by reference character I2. Said blocker also includes strip spacing and push-off means I3 adapted to space the strips of metal as they are wound on said blocks and to transfer the coiled strips of metal to a coil supporting and transfer car I4.
The slitter I2 may be of any well known type which is adapted to longitudinally slit strip metal into a plurality of narrow strips. A pair of guide rolls I5, I5 are provided at the discharge end of said slitter, to guide the metal over a collapsible guide plate I 6 and upwardly or downwardly to the blocks II, I I. Said blocks are adapted to have alternate strips of the slit metal detachably se cured thereto, for separately coiling said strips of metal and permitting them to be transferred therefrom onto the transfer car I4, by the coil transferring mechanism I3.
The blocks II, II are of a collapsible type and each of said blocks is adapted to grip the ends of the strips of metal when inserted in a slot II, extending along its face. Said blocks are each provided with clamping means for gripping the ends of the strips, which is so arranged as to permit the metal to be removed from the end Figures 5 and 6). A chain and sprocket drive 29, within said housing, connects said shaft with the lower drum shaft I9, for driving said shaft. A pair of meshing spur gears and a chain and sprocket drive 3| connects said shaft 2'! with the upper drum shaft I9, for driving said shaft at the same rate of speed as the speed of rotation of said lower shaft. A hand wheel 32 is keyed to each shaft I 9 to permit said shafts and collapsible blocks to be turned by hand to properly position said blocks for insertion of the leading ends of the coils in the slots I1, I1, "and to properly position,said blocks for removing the coils of strip metal therefrom.
Referring now to Figures 7 to 13 inclusive and certain details of construction of the collapsible blocks II, II, said blocks are each of a similar construction, so one only need herein be shown and described in detail. The lower block II is shown in detail in these figures and includes a drum segment 33 mounted on the shaft I9 on a plurality of spaced. hubs 34, 34, herein shown as being keyed to said shaft. Said drum segment has a longitudinally extending relatively flat recessed portion 35, which leads to an arcuate outer periphery of said drum segment in an inclined direction. A shoe 36 is secured to said recessed portion and extends outwardly along the inclined surface of said inclined portion to and along the outer periphery of said drum segments,
' and the portion extending along the outer periphof the block when collapsed, by sliding it along the block by the push-off means I3 without removing the leading end of the metal from said slot, as will more clearly appear as this specification proceeds. Said blocks, as herein shown, are mounted on vertically spaced parallel shafts I9, I9, the lower of which shafts is spaced a slight distance in advance of said upper shaftfor increasing the accessibility to each of said blocks. Said shafts are journaled in and project from a housing 20, mounted on a base frame-2|, for the blocker. The arrangement is such that said blocks, along with their supporting shafts may readily be removed from the housing 20, so different diameters of blocks may be used to take care of different thicknesses of metal.
The drive to the shafts I9, I9 and collapsible blocks II, II includes a motor-23, mounted on Said motor has driving connection with a variable speed reduction drive indi cated generally by reference character 24, through a vari-torque coupling 25 and a V-belt drive 26. The vari-torque coupling 25 may be of a type similar to that illustrated and described in Patent No. 2,135,929 which issued to Frank J. Wood on November 8, 1938, and is adapted to automatically vary the speed of the shafts I9, I9 as the strip metal is wound on the blocks II, II and the torque thereon increases, to provide a tion drive 24 may be of any well known form,
ery of said drum segment forms an outer surface for said drum segment (see Figures 8 and 9).
' A plurality of, collapsible drum segments 40 and 4 I are pivotally connected. to opposite sides of the drum segment 33 on transverse shafts 42 and 43 respectively." The space between the end of the drum segment 4| and the inclined portion of the shoe 36 is filled by'a member 44 mounted on the outer side of a'plurality of spaced blocks 45, 45 spaced along said drum and secured to said shoe, as by rivets 46, 46. Said member forms a continnation of the outer periphery of the drum and has an end 41, adjacent but spaced from the inclined portion 48 of the transverse shoe 36 a distance sufficient to form the slot IT, for the insertion of which is manually adjustable to vary the winding speed of the blocks II, II, and is not herein shown or described in detail, since it is no part of my present invention.
The variable speed reduction drive 24 has driving connection with a shaft 21, journaled in the housing 20, through a flexible coupling 28 (see incline portion of the shoe 36 is provided with a longitudinally slotted portion 49, in alignment with the slot IT, to receive the leading ends of the'strip metal.
The strips of metal are held to said drum by a plurality of engaging members 50, 50 engaging the leading ends thereof. A plurality of said engaging members are adapted to engage each strip of metal, and eachset of said engaging memhers is pivotally mounted on a longitudinally extending bar 5|,mounted at its ends on a pair of parallel spaced rocking arms 52, 52, secured to the transverse shaft 43. Said shaftextends longitudinally of said drum and is pivotally mounted in spaced lugs 54, 54, projecting outwardly from the recessed portion of said drum segment 33, and
in end plates 55, 55 of said drum. Said shaft likewise extends through spaced lugs 53, 53 formed integrally with the drum segment H and extending along opposite sides of the lugs 54, 54, and is secured to said lugs 53, 53, so said arms 52, 52 will be rocked by said shaft upon rocking movement of the drum segment 4I dur ing expansion or collapsing of the block, to move said engaging members 50, 59 to a released position. upon collapsing of the block. Leaf springs 56, 56, mounted on said arms, have engagement with said engaging members 50, 50, to release the axes of the shafts 42 and 43, to expand or collapse the drum, by means of a cam 51 1 3 naled at its endsin the end plates 55, 55. Adjacent ends orsaid drum segments are held in engagement with said cam by means of a plurality of spaced tension springs59, 59 connected at their ends toinwardl 'y extending flanged portions of said drum segments The end of the shaft of the cam 51;- n the outer side of said block, projects beyond the end plate 55 and is slotted to receive an end .of a hand lever 60. Said hand lever is provided to turn said cam from the position shown in Figure 13, to the position shown in "Figure'li, to expand the drum segments 40 and 4| and hold them in an expanded position; or to move said cam from the position shown in Figure 8 to the position shownin Figure 13, to permit said drum to be collapsed by tension of the metal wound thereon and by the springs 59, 59. Said hand lever is transversely pivoted to said end of said shaft by means of a pivotal pin 6| so it may be pivoted in an upward direction, when said cam is in either of the positions shown in Figures 8 or 13, to register for engagement with a notched locking plate 63 on the outside of the outer end plate55, which serves to lock said hand lever in position.
The outer end plate 55 is slotted as is indicated by reference character 65 and the slotted portion thereof is in alignment with the slot |1, so the bent leading ends of the strip metal may pass therethrough, to permit removal of the coils from the end of the block upon collapsing of the block and the release of the clamping means which hold the leading ends of the strips to the block.
Referring now in particular to the push-off and spacing mechanism, for pushing the coils from the ends of the blocks onto the transfer car I4, a push-off plate 66 is provided. Said push-01f plate, as herein shown, is supported on rollers 61, 61, which ride along the base frame 2| and which are mounted on brackets 68, 88, pro- Jecting from the lower end of said plate, in a direction towards the blocks I H. Said plate extends vertically from said rollers to a position above the upper block and is provided with two semi-circular recessed portions, which partially encircle said blocks as said plate. moves therealong.
A pair of vertically spaced fluid cylinders 68,
69' are provided to ,move the push-off plate 86,
acrossthe faces fof-"said"blocks, Said cylinders are suitably secured to'the' housing 20 and have, pistons 10,"!!! movable tlicrein,'with piston rods 1|, 1| extensible therefrom Said piston rods are Y secured at their outer ends to the side of the push-off plate 66 opposite f 'romsaid blocks.
A plurality of--'parallcl vertically and horizontally spaced guide shafts 14, 14 extend horizontally from opposite'sides of the push-off plate 66 and are suitably secured thereto, intermediate their ends, on hubs l5, l5 projecting from said plate in adirection away from the blocks Said guide shafts, as herein shown, are slidably guided in laterally spaced bearings 16, 15. The
uppermost'of' said bearings is mounted in a pair of laterally spaced brackets 71, 71 projecting upwardly from the housing 20, while the intermediate shafts are'mounted'in laterally and vertically spaced brackets 18,;78 projecting rearwardly from said housing (see Figure 4 The lowermost plurality of strip spacing and guiding members 8|, 8| mounted thereon, which partially encircle the blocks H, on the side thereof adjacent the guide rolls I5, I5, and serve to guide alternate strips of metal onto said blocks and to hold said strips in spaced relation with respect to each other.
The upper spacing and guiding members 8|, 8| are slidably mounted onthe two upper guide shafts 14, 14 and are held in spaced relation with respect to each other by means of spacer sleeves 85, '85 and nuts 86, 86, threaded on the ends of saidshafts. Said nuts abut collars 81, 81, which abut the end spacing and guiding members. Said spacer sleeves are of a length equal to substantially the width of the strip metal, to space said spacing and guiding members apart a distance equal to substantially the width or the strip metal it is desired to wind on said block's, it being understood' that different widths of spacer sleeves are provided for different widths of'metal.
The lower spacing and'guiding members 8|, 8| are mounted on the two lower shafts 14, 14 in the same manner the'upper pacing and guiding members are mounted on the two upper shafts,,
and are of a construction similar to the upper spacing and guiding members but are spaced between said upper spacing and guiding mem-' members.
As herein shown, each spacing and guiding member 8| includes a pair of spacer plates 89, B8 spaced apart by a ring segment 9|, herein shown as being formed integrally with sleeves 92, 92, mounted on the shafts 74, 14. Each of said spacer plates has a semi-circular cut-out portion which partially encircles the block H, and said ring segment is herein shown as being of a slightly larger diameter than the cut-out portions of said spacer plates.
A hold-down means is provided for said upper and lower drums, to hold the wound coils from unwinding. Said hold-down means, as herein shown, includes a transversely extending holddown shoe 93 mounted on the ends of spaced arms 94, 94 and movable to a position to engage each coil on the block. Said arms are mounted on squared shafts 95, 95 extending parallel to the faces of'said drums. Said upper and lower I squared shafts are mounted in vertically spaced brackets 96, 96 formed from supporting angles coiled strip metal.
in a direction away from said blocks. As shown in Figures 2 and 14 of the drawings, the upper hold-down projects upwardly from its respective shaft 96, while the lower hold-down projects downwardly from its respective shaft.
The means for turning the squared shafts 96, 95 and for operating the hold-down shoes 99, 99 includes arcuately formed arms 91, 91, one of said arms being mounted on each of said shafts and being disposed adjacent the brackets 18, 18 projecting from the housing 20. Said arms are herein shown as being mounted between the blocking side of the side walls of said brackets 18, 18 and restraining brackets 98, 98, secured to and projecting from the blocking sides of said side walls. Said restraining brackets serve to restrain said arms from rectilinear movement when the coils are pushed from the blocks II, II by rectilinear movement of the push-oil plate 66 and the spacing and guiding members BI, 8i along said blocks.
The adjacent ends of the arcuate arms 91, 91 have teeth out therein and are in the form of an arcuate segment of a gear. Said teeth are meshed with teeth on opposite sides of a rack bar'99, slidably mounted on the side wall of the housing 20, which is disposed adjacent the blocks II, II. Said rack is provided with an upturned outer gripping end I00, adapted to be engaged by the hand so that movement of said rack will pivot the shafts 95, 95 and engage the hold-downs with or disengage them from the A pawl and ratchet indicated generally by reference character IOI is provided to hold said rack' in position (see Figure 2).
The transfer car I4 includes an upright frame I91 provided with parallel spaced depending legs I08, I 08, upon which are mounted supporting and H6, H6 are in the form of sectors of circles of substantially the same diameter as the diameter of the blocks I I, II, and the outer ends of said sectors are abutted by circular plates I20, I20, which are secured thereto. A pin I2I is secured to and projects rearwardly from each of said plates and a key I22, extending through said pin and abuttin the outer side of the frame I01, holds said pin and plate to said frame. Each of said coil supporting sectors is provided with a slotted portion I23 at its upper end, for the insertion of a lifting means, so the coils may be readily removed from said sectors.-
A hold-down means is provided adjacent each" coil supporting sector II6, to hold the trailing ends of the coils on said coil supporting sectors (see Figure 2). Each of said hold-downs includes a pair of laterally spaced lever arms I24, I24 having a hold-down shoe I25 connected therebetween, on the outer ends thereof. Said lever arms are mounted on vertically spaced horizontal transguiding rollers I09, I09. Said rollers ride along and extend within the insides of the webs of a pair of parallelspaced channels H0, H0, which extend transversely of the blocks II, II, along the blocking side thereof (see Figures 2, 3 and 4), A pair of parallel spaced guide strips III, III, mounted on and projecting upwardly from a plate II2 extending between and along said channels, are provided to engage the insides of the legs of said frame and serve as a guide-means for said transfer car (see Figures 3 and 4).
The means for moving said transfer car =I4 along the track formed by the channels H0, H0 includes a fluid pressure cylinder II3 having a piston rod I I4 extensible therefrom (see Figure 3). Said piston rod is connected at its forward end to a bracket II5 depending from the forward end of said transfer car, so that movement of said piston rod in one direction or another, caused by the admission of fluid pressure into one end or the other of said cylinder, will move said transfer car in a like manner.
The coils of metal are supported on the transfer car I4 on coil supporting sectors H6, H6, mounted on'shafts H1, I". Said shafts are mounted in the upright frame I01'and extend towards the blocks II, II and are so positioned on said frame as to be coaxial with the shafts I9, I9, when said transfer car is in position to receive coils from said blocks II, II. As herein shown, said coil supporting sectors and shafts are held from turning movement by means of wedge-shaped keys IIB, I I8, extending through said shafts and supporting hubs H9, H9, which hubs are formed integrally with said frame and extend therefrom in a direction from the blocks II, II (see Figure 3).
The outer sides of the coil supporting sectors verseiy extending shafts I26, I26, which are journaled in the frame I01. The means for operating said hold-downs includes a hand lever I21 secured to the lower of said shafts. A link I26 connected between the outer ends of lever arms I29, I29, secured to said shafts, serves to connect said shafts for operation together so that movement of said hand lever in a direction towards the sectors I I6, I I6 will simultaneously engage the upper and lower hold-down shoes I25,
I25 with their respective coils.
The collapsible guide plate I6 is transversely hinged intermediate its ends and is mounted at its rear on a transverse shaft I30 suitably mounted in a frame I3I, for the guide rolls I5, I5 (see Figure 2). The underside of the front end of said guide plate is beveled, and the beveled portion thereof slidably engages the upper sides of the lower spacerplates 89, 89, and when in a collapsed position, is supported by an upright supporting member I32, projecting upwardly from the base frame 2I.
The means for extending said guide plate includes an arm I99 secured to the transverse shaft I30 and projecting angularly forwardly and upwardly therefrom. A link I34 is pivotally connected to the free end of said arm and depends therefrom. The lower end of said link is pivotally connected with one end of a foot operated lever I35, pivoted intermediate its ends to the base frame 2i and-adapted to be operated by foot pressure on its end opposite from said link, When the foot lever I35 is depressed, the guide plate I6 will be extended to the position shown in Figure 2, to permit strip to pass thereover and be attached to the blocks II, II in the hereinbefore described manner, and when foot pressure is relieved from said lever, said guide plate will collapse to the position shown by broken lines in Figure 2 and will be out of the way of the strips of metal as they are wound on their respective blocks.
In operation, the strips of metal are trained over the guide roll I5 between the spacing and guiding members 89, 89 so they may be alternately connected at their free ends to the blocks II, II by insertion of the ends thereof in the slots I1, I! of said blocks, as desired.
It should here be noted that as the strip metal is slit, the edges of alternate strips of metal are burred in upward and downward directions. In coiling the metal it is desirable that the burrs of all of the coils extend in the same direction. Thus if it is desired that the burrs be on the on the lower block I I, which rotates in a counterclockwise direction; the second strip is connected to and wound on the upper ;block I I which rotates in a clockwise direction; the third strip is connected to and wound on the lower block, and so "on i hen the slit strips of; metal have been connected to their respectiveblocks, foot pressure is.
removed from the lever I35 and the guide plate I6. is collapsed so as to be out of the way of the strip metal. The motor 23 is then started to vari-tordue coupling 25 in a well known manner,
to. vary in accordance with thetorque exerted by said blocks and to provide a substantially constant pull on the strip metal during the entire winding operation. When the strips of metal are fully wound on their respective blocks, .the holddown shoes 93, 93 are engaged with the free ends thereof and the transfer car I4 is moved by the cylinder II3 to a position where the coil supporting sectors IIB, Bare in alignment with the blocks II, II. At this time-,said blocks may be turned by the hand wheels 32, 32 until the slots 65, 65 are beneath said coil supporting sectors, so the .coils may be .slidably moved from the ends of said blocks. onto said sectors, and the bent-over leading ends of the coils-will be free from said sectors. Fluid under pressure, such as air, may then be admitted to the head ends of thefluid cylinders 69, 69, to cause the push-off plate 66 and the spacing andguiding members 8|, 8| to move the coilsfrom the ends of said blocks onto said coil'supporting sectors. As said coils are transferred onto said sectors, and before the hold-down shoes 93, 93 are released, the hold-down shoes I25, I25 on the transfercar I4,
adapted to have clampingengagement with the leading ends 01' a plurality of strips of metal, coil transferring mechanism adapted to receive and support the coiled strip metal, and means .for
' guiding thestrips of metal onto said blocks in spaced apart relation with respect to each other and for pushing the coils from said blocks in an endwise direction onto said coil transferring mechanism including a push-off plate movable along said blocks, and spacing members mounted on said push -off plat and movable therei with, for'spacing the strip metal as it is wound which face the hold-down shoes 93, 93, are engaged with said coils, to prevent their unwinding. The hold-down shoes 93, 93 are then released and fluid underpress ure may then be admitted to the head end of the cylinder II3 to move said transfer car andcoils away from said blocks, the hold-down shoes I25, I25 still being in engagement with said coils- When said transfer car has been moved away from said blocks by said cylinder and the piston rod IN, the individual coils may be handed to prevent ,their'un'winding, and the hold-down shoes I25, I25 may then be released. Bars'or hooks may then beinserted in the slots I23, I23 and chains connected with a .suitable lifting device, such as-a crane, may be While we have herein shown and described one form in which our invention may be embodied, it will beunderstood that the construction thereof and the arrangement of the various parts may be altered without departing frorirthe spirit and scope thereof.
