Definitions

  • This invention relates to apparatus for processing and handling coils of strip metal.
  • a tight wound coil of metal strip is recoiled into open or loose coil form in which the laps of the coil are spaced apart from each other.
  • This open coiling operation is customarily effected by recoiling a tight wound coil of metal on a vertical axis turntable while winding in between the laps of the coil a spacer strand of the proper size to give the desired lap spacing.
  • the apparatus of the present invention greatly expedites and simplifies the handling of untreated tight coils of strip metal prior to and during open coiling thereof and expedites and simplifies the recoiling of a treated open coil back into tight coil form and the subsequent tilting of the tight coil into horizontal axis position for further handling.
  • the apparatus of the present invention is also adapted to receive horizontal axis coils of strip from a conveyor and rapidly and accurately locate and support them in horizontal axis position for pay off to a temper mill or other strip processing apparatus.
  • strip coil handling apparatus which does not require the use of separate coil up-ending devices such as have previously been employed to tilt the coils from horizontal axis position to vertical axis position and vice versa; and the provision of strip coil processing and handling apparatus whereby the output of a tight or open coil strip processing installation may be increased, the operating costs reduced, and the possibility of damage to the edges of the strip in the coils greatly reduced.
  • the coiler apparatus of the present invention broadly speaking, embodies a frame member mounted for pivotal movement, a pair of rotatable mandrels operably mounted on this frame member, means for rotating the mandrels on the frame, and means for pivoting the frame member in conjunction with the mandrels.
  • the frame member is mounted for pivoting about a substantially horizontal axis of rotation and rotatably supports a coil support or turntable at each end, a collapsible and expandable mandrel being associated with each turntable for rotation therewith, said mandrels in some cases being of different sizes to permit paying off of coils of one core size and winding on of coils of another core size to prevent coil breaks in the strip metal after it has been annealed.
  • coil infeed and outfeed conveyor means are provided which cooperate with coil hoist means for applying and removing coils to and from, respectively, the aforesaid mandrels when the frame member is pivoted into corresponding selected positions.
  • FIGURE 1 is a perspective view of apparatus embodying the present invention designed particularly for use in the open coil process and including the coil conveying and lifting equipment associated therewith;
  • FIGURE 2 is a view, partially in cross-section, of the coiler apparatus depicted in FIGURE 1;
  • FIGURE 3 is a plan view, partly in horizontal crosssection, of a somewhat modified form of my apparatus also designed particularly for use with open coils.
  • FIGURE 4 is an enlarged fragmentary view illustrating in greater detail the clutch mechanism between the turntables and the drive means of the apparatus of FIG- URES 2 or 3.
  • FIGURE 5 is a perspective View of a modified form of my invention which is particularly designed for transferring horizontal axis tight coils from a conveyor into position for feeding the strip to a rolling mill and rotat ably supporting the coil during pay-off to the mill.
  • FIG. 1 With particular attention to the embodiment of FIGURES 1 and 2, it will be seen that tightly wound coils 1 are delivered from a suitable supply depot (not shown) into close proximity with the coiler unit (which is generally indicated by the reference character 3) by suitable infeed conveyor means such as the chain conveyor 2.
  • a coil hoist car 4 having wheels 5 adapted to travel upon rails or tracks 6 and actuated by suitable means such as a hydraulic cylinder (not shown), is adapted to be moved beneath the forwardmost infed tight coil 1 into a position to raise the latter off the conveyor 2.
  • the coil hoist platform 7 of the coil hoist car 4 can be raised by means of a hydraulic cylinder 8 in order to lift the forwardmost coil 1 into a position such that its open center or eye is in alignment with the collapsible and expandable pay off mandrel 9 when such is disposed in horizontal axis position, as will be more fully explained hereinafter.
  • a similar coil outfeed chain conveyor means 29 is located at a diametrically opposed location from the previously described coil infeed conveyor 2.
  • a coil hoist car 10 incorporating a coil hoist platform 11 adapted to be raised and lowered by a hydraulic cylinder 12, is associated with the conveyor means 29.
  • This coil hoist car 10 includes wheels 13 which travel upon the rails 14 and the car may be moved on the rails by a hydraulic cylinder or other suitable means (not shown).
  • the outfeed conveyor 29 receives annealed coils 1b from the expandable and collapsible mandrel 15 of the coiler unit 3 and extends in the opposite direction from the infeed conveyor 2.
  • the tight-rewinding mandrel 15 is preferably larger in diameter than the pay off mandrel 9.
  • the pay off mandrel 9 may have a diameter of 24 inches while the tight winding mandrel may have a diameter of 36 inches.
  • the expandable mandrels 9 and 15 can be rotated, for example in opposite directions, by a drive motor 16.
  • This motor has a brake 17 effective on the outer end of its shaft and is connected to the mandrels 9 and 15 through a coupling 13, a gear reducer 19, a further coupling 20, shaft 23 and suitable gear and cluch mechanisms located within the housing 21 of the coiler 3 and which will be described in detail shortly.
  • the coiler unit 3 is so constructed that the expandable and collapsible mandrels 9 and 15 can be simultaneously swung or rotated about the extended center line of shaft 23 in a substantially vertical plane from the vertically extending positions shown in the drawings into horizontally extending positions and returned to vertical position.
  • the hoist platform 7 is then lowered and at the same time the mandrel 9 is expanded, thereby securing the coil in place on the mandrel. Thereafter, the coiler 3 is rotated 90 in the direction of the arrow in FIGURE 1 into vertical position with the mandrel 9 extending upwardly as seen in FIGURE 1.
  • the tight coil 1 may then be payed off onto a suitable loose coil turntable (not shown) to produce a loose or open coil ready for further treatment.
  • the loose coil turntable and ancillary equipment have not been shown since details thereof are not necessary to understanding, and form no part of, the present invention.
  • the coiler 3 After paying off of the tight wound coil 1 from mandrel 9 has been completed the coiler 3 is rotated 180 (the hoist cars 4 and 10 having been backed out of the way) to bring the larger diameter mandrel into upstanding vertical operating position to accept for tight rewinding the strip from a treated loose or open coil which has been placed on an adjacent loose coil turntable (which as noted above is not shown in the drawings). It will be understood that it is possible to use the coiler unit 3 with only a single loose coil turntable, but it is preferable to provide two loose coil turntables in order to permit better continuity in operation.
  • the outer end of the strip of the open coil which is on the loose coil turntable is fed into suitable gripper means (not shown but which may be of any well known type) 011 the larger diameter mandrel 15 and the open coil is then tight wound onto the mandrel 15 by means of the drive motor 16.
  • suitable gripper means 011 the larger diameter mandrel 15 and the open coil is then tight wound onto the mandrel 15 by means of the drive motor 16.
  • the coiler 3 is rotated 90 in the direction of the arrow in FIGURE 1 to bring the mandrel 15 into a position such that the tight wound treated coil located thereon is directed towards the exit or delivery side of the coiler assembly, i.e., towards the delivery or outfeed conveyor 29.
  • the coil hoist car 10 is moved into proper position beneath the coil on the mandrel 15 and the platform 11 is raised by the hydraulic cylinder 12 so as to contact the coil, the mandrel 15 then being collapsed so that the platform 11 supports the coil.
  • This coil is then moved by the coil hoist car 10 off of the now horizontal mandrel 15 to a position above the conveyor means 29 and lowered thereon by the hydraulic cylinder 12.
  • the conveyor means 29 then transport the annealed or otherwise treated tight coil 1b out of the way towards a suitable storage area or other location. It is of particular significance to note that, at the same time that the treated coil 11) is being placed on the conveyor 29 another untreated coil 1 from the conveyor 2 is moved into position on the now horizontal pay off mandrel 9 by the car 4 after which the aforedescribed operating cycle may be repeated.
  • FIGURE 2 illustrates the internal structure of coiler unit 3.
  • Cylindrical frame member or housing 21 is supported for rotation about an axis extending transversely of its own longitudinal axis upon antifriction bearings 24 and 25 on coaxial shafts 22 and 23.
  • the shaft 23 is rotatably supported in an antifriction bearing 26 carried by a pillow block 27 and the shaft 22 is similarly rotatably supported on an antifriction bearing carried by the pillow block 28.
  • the shaft 22 is equipped at its outer end with brake means comprising a brake drum 30 which is keyed or otherwise suitably connected to shaft 22 and a brake shoe 36a cooperable with brake drum 30 in the usual manner.
  • Shaft 22 is also provided with a bevel gear 31 at its inner end, this gear being connected to the shaft as by keying.
  • a second bevel gear 32 is mounted on the inner end of the opposite coaxial shaft 23 which is operably connected to the drive motor 16 by the coupling 20, gear reducer 19 and coupling 18.

  • the pillow block 28 and brake means 30, 30a are mounted upon a common base or support 34, also set upon a suitable foundation.
  • Antifriction bearings 35 and 36 are mounted at the ends (top and bottom as seen in FIGURE 2) of the cylindrical frame member or housing 21.
  • the bearing 35 rotatably supports a circular turntable 37 which in turn supports the bevel gear 38 which is positioned to mesh with the aforementioned gears 31 and 32.
  • the clutch 85 which is clearly shown in FIGURE 4 and will be described in detail later, is adapted to connect or disconnect the gear 38 to or from the turntable 37.
  • the bearing 36 supports a similar circular turntable 39 which is connected through a clutch to the bevel gear 40 which likewise meshes with the bevel gears 31 and 32.
  • the bevel gears 31, 32, 38 and 40 provide a differential gear arrangement capable of not only imparting opposite rotational movement to the expandable and collapsible mandrels 9 and 15, but, and as will be further explained later, which can be differentially driven, by actuating the brake means 30, 30a, so as to also rotate or revolve the cylindrical housing 21 and the mandrels 9 and 15 as a unit about the common center line of shafts 22 and 23 in a substantially vertical plane.
  • the clutches 85 and 86 are engaged driving connections are established between the gears 38 and 4t and turntables and when the clutches are disengaged the driving connections are broken and the turntables are free to rotate on the housing 21.
  • the clutches 85 and 86 may be operated independently of each other so that the turntables 37 and 39 and the mandrels 9 and 15 carried thereby may be independently connected to and disconnected from the drive motor 16.
  • a shaft 41 is rigidly connected to and extends through the turntable 37 and supports and drives the smaller diameter mandrel 9 which is secured thereto and is rotatable therewith.
  • Another similar shaft 42 is rigidly connected to and extends outwardly through turntable 39 for supporting and driving the larger diameter expandable mandrel 15.
  • the mandrels 9 and 15 are adapted to be selectively expanded and contracted by means of suitable hydraulically actuated mechanisms (not shown) embodied in said mandrels.
  • Hydraulic supply lines 43 and 44 extend through a suitable bore in the shaft 22, rotary hydraulic joints 47 at the inner end of shaft 22, and shafts 41 and 42 to these mandrel actuating mechanisms.
  • a second pair of hydraulic supply lines 45 and 46 extend through shaft 22 and rotary joints 47 to the clutches 85 and 86 respectively and con-duct to these clutches the fluid pressure which effects engagement and disengagement thereof.
  • the hydraulic lines 43, 44, ,5 and 46 have three way valves 43, 4a, 4 5 and 46 therein and are connected to a pressure supply header 100. Fluid under pressure is supplied to header through pipe 101 by pump 102 and pressure relief lines 43", 44", 45" and 40" extend from valves 43, 44, 45 and 46' back to the fluid supply sump or container 103.
  • the operation of the valves 45' and 4a to control the clutches 85 and 86 will be explained later.
  • the vertically extending shaft 41 which is keyed to the turntable 37 by a key 105, extends downwardly below the turntable and has mounted thereon and keyed thereto an upper clutch housing member 106.
  • a series of driven clutch plates or discs 107 have a vertically slidable keyed or splined connection to the inner hub portion 106' of the clutch housing 106.
  • the lower clutch housing member 108 is secured to the gear 38 as by screws 109 and has an upwardly extending inwardly splined cylindrical ring portion .110 in which the clutch driving discs 111 are supported in interleaved relation with the driven discs 107.
  • the outer peripheries of discs 111 are suitably notched to receive the splines on the inner face of the ring portion 110 of the clutch housing member 108 in well-known manner.
  • the upper clutch housing member 106 in addition to supporting the driven clutch discs 107, forms an annular fluid pressure chamber or cylinder .112 in which is mounted a vertically movable annular piston 113.
  • a fluid pres sure conducting passage 114 extends from the upper portion of chamber 112 into the shaft 41 and downwardly therethrough where it connects with the hydraulic supply line 45 through the rotary hydraulic connection 47.
  • the clutch 86 which is adapted to effect driving connection between the gear 40 and the turntable 39, is similar in construction to that just described and is similarly connected to the fluid pressure supply line 46.
  • the valve 45 is set in the posit-ion shown in FIGURE 2 in which a dire-ct connection is provided between the fluid pressure header 100 and the pressure line 45.
  • AS the pump 102 maintains fluid under the proper pressure in the header 100 this pressure is applied against the top of the piston 113, moving it downwardly in the annular cylinder 112 and causing it to press the driven clutch discs 107 and the driving clutch discs 111 tightly together to effect driving connection therebetween.
  • valve 45 is turned clockwise through 90 from the position of FIGURE 2 so that the fluid pressure line 45 is connected to the pressure release line 45', thus relieving the fluid pressure in the cylinder 112 with accompanying release of the engagement of the clutch 85.
  • valves 45' and 46 may be set as desired so that either one or both of the turntables 3'7 and 39 may be positively connected to the drive means or released therefrom as desired.

These sockets cooperate with a locking pin 49, which is adapted to be advanced and retracted by a hydraulic cylinder 50 supported upon the pillow block 27.
  • This locking pin 49 may be selectively inserted in the three sockets 4 8 to fix the position of the coiler unit 3 in the desired location about the axes of shafts 22 and 23 for performing the operations of sliding a coil over and onto the smaller diameter mandrel 9 or removing a coil from the larger mandrel 15 when these mandrels are in horizontal position, or paying strip off from the smaller mandrel 9 or winding strip onto the larger mandrel 15 when the mandrels are in vertical position.
  • the drive motor 16 driving through the gear reducer 19 and shaft 23, may be operated to rotate bevel gear 32 which, in turn, will rotate the bevel gears 38 and 40.
  • the brake means 30-3011 since the brake means 30-3011 has been released the bevel gear 31 is free to rotate and consequently, if the clutches and 86 are engaged, the turntables 37 and 39, as well as the mandrels 9 and 15 which are connected to bevel gears 38 and 40, will rotate, but in opposite directions.
  • the previously described arrangement permits selective vertical positioning and rotation or non-rotation of the expandable mandrels 9 and 15 for either the paying off or tight winding on of a coil of metal strip. Moreover it permits rotating the coiler unit 3 as a whole to place the mandrels 9 and 15 in horizontal position for simultaneously receiving a coil to be treated and for discharging a treated coil. It is, of course, to be understood that other physical constructions which incorporate the inventive concepts but employ different means might be employed for accomplishing the desired result. One example of such a modified apparatus is illustrated in FIGURE 3.

  • the pinion 67 meshes with a spur gear 69 fixedly mounted upon a shaft 70 which is supported in bearing blocks 71, 72 and 73 for rotation within the housing 63.
  • This shaft 70 also has fixedly mounted thereon a wide pinion 74 which meshes with a wide face spur gear 75 fixedly mounted on the hollow tubular shaft 60.
  • the drive motor 16 is connected through a suitable coupling 90 with a shaft 77 supported for rotation in bearings 76 and 78.
  • This shaft 77 in turn is provided with a pair of spaced and freely rotatable pinions 79 and 80.
  • a suitable clutch means 81 which permits selective coupling of either the pinion 79 or the pinion 80 to the shaft 77.
  • Pinion 79 is secured to a sleeve 83 which in turn is connected to a releasable brake 84 which is adapted to permit or prevent rotation of sleeve 83 and pinion 79 on shaft 77.
  • FIGURE 3 it is not necessary to provide a brake device for locking one of the bevel gears of the set 31, 32, 38 and 40 to permit rotation of the entire coiler unit 3 as a whole since, in FIGURE 3, separate gear trains are provided one of which is capable of imparting rotational movement to the expandable mandrels 9 and 15 about their own axes and the other of which is constructed so that the coiler unit 3, including the mandrels 9 and 15, can be turned or rotated through 360 in a substantially vertical plane, in the same manner and for the same reasons explained in conjunction with the description of FIGURES l and 2.
  • FIG- URE 3 is substantially similar to the embodiment of FIG- URES 1 and 2 and the manner of operation is substantially analogous to what has been previously described herein.
  • FIGURE 5 there is illustrated a modified form of my apparatus for processing and handling coils of strip metal which is particularly designed for receiving tight wound coils of strip, disposed with their axes horizontal, from a conveyor and rapidly and accurately positioning the coils for, and supporting them during, pay off of the strip to further processing apparatu such as a temper mill.
  • a chain conveyor 121) is adapted to bring tight coils 121 into position to be picked up on the elevator 122 of a coil hoist and transfer car 123 which may be generally similar to the car 4 and its elevator or platform 7 shown in FIGURE 1.
  • the coil handling unit of FIGURE 5 includes a generally cylindrical housing 124 which carries coil supporting platforms or turntables 125 and 126 at it opposite ends. Expandable mandrels 127 and 128 are carried by and are rotatable with the coil support tables 125 and 126 respectively. Clutches, similar to clutches 85 and 86 of FIGURES 1-4, are provided for independently controlling the driving connection to the mandrels 127 and 128.
  • the housing 124 is supported on a horizontal shaft or trunnion 129 for rotation about its transverse axis.
  • the drive motor 130 is connected through a suitable gear box 131, which may be similar to that illustrated in FIGURE 3, so that the housing 124, coil supports 125 and 126, and mandrels 127 and 128 may be rotated as a unit about the horizontal axis of trunnion 129, and whereby the mandrels 127 and 128 may also be rotated about their own axes when the clutches referred to above are engaged.
  • a four high type rolling mill 132 is located to receive strip from a coil which is supported on mandrel 128 when the apparatus is in the condition seen in FIGURE 5.
  • strip from the coil 133 which is supported on the mandrel 128, is being fed through the mill 132 and the mandrel 128 and supporting table 126 are preferably connected to the driving mechanism and rotated at the desired speed.
  • a coil 134 has been removed from the conveyor 12% by the transfer car 123.
  • the car will be moved on its tracks 123' until coil 134 is properly positioned on the now stationary non-rotating mandrel 127 which is then expanded.
  • the elevator 122 will then be lowered and car 123 retracted.
  • the entire unit After the coil 123 has been completely paid off the entire unit will be rotated counterclockwise as seen in FIGURE 5 through so that the positions of the mandrels 127 and 128 will be reversed.
  • the strip of coil 134 will then be properly positioned to be fed through the mill 132 and the mandrel 127 is started to rotate to feed the strip to the mill. While this operation is taking place the coil car 123 will pick up another coil 121 from the conveyor 120 and position it on the now stationary mandrel 128. This cycle is repeated for as long as the installation is maintained in operation.
  • Substantially the same apparatus as shown in FIGURE 5 may also be used for coiling strip as it is delivered from a rolling mill or other processing operation and for transferring the so formed coils to a conveyor for removal. Such an operation will be understood if it is assumed that the strip in FIGURE 5 is leaving the mill 132 and is moving in a direction opposite to that indicated by the arrow in FIGURE 5 and is being wound onto the driven mandrel 128.
  • Apparatus for processing and handling coils of strip metal including a frame member mounted on a pair of shafts for pivotal movement about a substantially horizontal axis, releasable locking means for holding said frame member against such pivotal movement, a pair of oppositely directed mandrels mounted for rotation on said frame member and having their axes extending at 90 to said horizontal axis of said frame member, and drive means adapted selectively to rotate said mandrels about their axes, while said frame member is held stationary by said locking means or to turn said frame member together with said mandrels as a unit about said horizontal axis of said frame member when said locking member is released.
  • Apparatus for processing and handling coils of strip metal as defined in claim l including oppositely facing coil supporting turntables rotatably supported on said frame member coaxially and rotatably with said mandrels, said turntables being horizontally disposed when said axes of said mandrels are vertically disposed.
  • Apparatus for processing and handling coils of strip metal as defined in claim 1 wherein said means for rotating said mandrels about their axes is adapted to rotate one of said mandrels while the other remains stationary.
  • Apparatus for processing and handling coils of strip metal as defined in claim 1 including a pair of supporting 1Q shafts extending coaxially with said horizontal axis and projecting from opposite sides of said frame member, a base structure for the apparatus, bearing means on said base structure for said supporting shafts, the inner ends of said shafts being spaced apart and having bevel gears mounted thereon, a pair of oppositely extending mandrel shafts rotatably supported on said frame member for carrying said mandrels, said mandrel shafts being coaxially disposed relative to each other and having their inner ends spaced apart, bevel gears mounted on said inner ends of said mandrel shafts and meshing with said bevel gears on said supporting shafts to form a differential gear arrangement, means for driving one of said supporting shafts, and brake means for preventing rotation of the other of said supporting shafts.
  • Apparatus for processing and handling coils of strip metal as defined in claim 1 wherein said means for rotating said mandrels and said means for turning said frame member about said horizontal axis include a differential gear means, a motor connected to one of said supporting shafts for driving said differential gear means, and means for braking the other of said supporting shafts whereby said differential gear means will effect independent and opposite rotation of said mandrels.
  • Apparatus for handling coils of strip metal as defined in claim 1 wherein said means for rotating said mandrels about their axes includes independently operable clutch means between said rotating means and said mandrels whereby either one of said mandrels may be rotated while the other mandrel remains stationary.
