United States Patent diana Filed Oct. 31`, 1958, Ser. No. 770,969 18 Claims. (Cl. 271-68) This invention relates to appaartus for piling metal sheets as they are received from a high speed processing line .and is more particularly concerned with improvements in edge aligning devices for such apparatus.
In the handling of metal sheets where the sheets are delivered from a high speed processing line apparatus has heretofore been provided for accumulating the sheets in a pile on a suitable support such as van elevator beneath an overhead delivery conveyor which apparatus includes mechanism for stopping the forward movement of the sheet and allowing the same to drop on the pile beneath the conveyor and mechanism for guiding the side edges of the sheets as they settle onto the pile. In order to adapt the piling apparatus to the handling of sheets of different size, it is desirable to mount the end stop mechanism and the side guide mechanisms so that they may be adjustably positioned to accommodate sheets of different size. Previous arrangements for providing adjustability for the end stop and side guide mechanisms have not been entirely satisfactory principally because of the time required to make the adjustments and the liability to damage through careless operation. It is an object, therefore, of the present invention to provide improved mechanism for adjustably mounting the end stop and side guides of a sheet piling apparatus so that the apparatus may be adjusted quickly to accommodate sheets of different size while it is in operation and the possibility of damage which may be caused by careless operation of the machine is minimized.
It is a more specific object of the invention to provide an apparatus for handling metal sheets which comprises an overhead conveyor for advancing successive metal sheets to a point for delivery onto a pile beneath the conveyor and end stop and side guide mechanisms which are mounted on slidable carriages connected to driven adjusting screws which are adapted to be rotated without stopping the conveyor for rapid and accurate positioning of the end stop and side guide mechanisms.
It is a further object of the invention to provide in a piler for handling metal sheets an overhead magnetic conveyor to which the sheets are delivered for deposit on a pile and .a pair of side guide devices having carriages at their opposite ends which are supported for transverse movement on end cross rails and equalizing mechanisms for holding the side guides in parallel relation while the distance between the guide faces thereof is adjusted.
It is another object of the invention to provide in a sheet piler having an overhead magnetic conveyor on which sheets are advanced for deposit n a pile on a support beneath the same, a pair of side guides having the ends thereof supported in sliding relation onV longitudinally spaced, transversely extending guide rails and a single adjusting screw connected .at its opposite ends to corresponding ends of the side guides for adjusting the distance between the guide faces of the side guides together with mechanism for holding the side guides in parallel relation as they are adjusted by operation of the adjusting screw.
It is still a further object of the invention to provide ru C@ carriages which are mounted on transversely extending guide rails so as to permit substantially free vertical movement of the side guides when a lifting force is applied thereto and thereby prevent accidental damage to the side guides or their mounting means.
It is another object of the invention to provide a sheet handling apparatus comprising an upright supporting frame, an overhead magnetic conveyor arranged on the frame for advancing successive metal sheets to a point for deposit on a pile beneath the same, side guide members carried in parallel relation on the supporting frame and having oppositely disposed, vertically extending sheet edge guiding faces, transversely extending, horizontally disposed, longitudinally spaced racks arranged on the frame, each of the side guide members having rotatably mounted thereon a longitudinally extending shaft which is provided `at opposite ends with pinions positioned for operating engagement with said racks and a single adjusting screw journaled in transversely extending relation at one end of the supporting frame which adjusting screw has a drive means and carries .a pair of traveling nuts adapted to be moved toward and from each other upon rotation of the screw, and the side guide members each having a bracket at the end adjacent the adjusting screw with means forming a separable connection between the nuts and the brackets whereby the distance between the side guide members is uniformly adjusted upon rotation of the screw.
It is another object of the invention to provide in a sheet piler having an upright support frame and an overhead belt type magnetic conveyor, an end stop mechanism with an adjustable mounting therefor, wherein the mounting comprises a carriage on which the end stop is supported, a track formation extending longitudinally of the piler on which the carriage is adapted to move, a driven adjusting screw mounted in parallel relation adjacent the rack formation, and having a traveling nut thereon which is connected to the carriage so as to move the carriage upon rotation of the screw.
It is a still further object of the invention to provide a piler mechanism having an overhead conveyor and means for mounting in adjustable relation thereon an end stop device wherein the mounting means comprises an elongate housing associated with the conveyor and forming a track for a carriage on which the end stop is suspended, an adjusting screw journaled in opposite ends of the housing and carrying a traveling nut which is connected to the carriage so as to move the carriage upon rotation of the screw, and a device for supporting the adjusting screw at one or more points intermediate its ends which is automatically positioned in accordance with the position of the carriage so as to prevent sag in the center portion of the screw. Y

FIGURE 14 is a longitudinal vertical section taken on the line 14-14 of FIGURE 11 to an enlarged scale and with portions broken away.
The apparatus which is illustrated in the drawings and which has incorporated therein the principal features of the invention is designed to receive individual metal sheets 10 (FIGURE 2) from a processing line, or the like, and to deposit the sheets one by one on a stack or pile 11 for removal from the apparatus.
The apparatus comprises an upright supporting frame structure 12 (FIGURES 1 to 4) on which there is mounted a horizontally disposed vertically reciprocable bed structure 13 for receiving a stack or pile of metal sheets 10 and an overhead magnetic conveyor 14, the latter being operable to deposit successive sheets 1) in stacked relation on the bed structure 13.
The supporting frame structure 12 comprises longitudinally spaced end frames 15 and 16 which are connected at the bottom by parallel, relatively spaced, longitudinally extending side beams 17 and at the top by similar longitudinally extending side beams 18.
The sheets 10 are delivered to the bottom run of the conveyor 14 of the apparatus by a feed conveyor 20 which is supported on a suitable bracket member 21 on the end frame 15. The conveyor 14 comprises a series of transversely spaced conveyor rail units 22 which rail units are the magnetic type, for example, as disclosed in my Patent No. 2,642,174, dated .Tune 16, 1953. The rail units 22 are supported at the receiving end of the apparatus on a cross beam 23 extending between vertical support brackets 24 on the upper portion of the end frame 15. At the other end of the apparatus the rail units 22 are supported on a cross beam 25 which extends between the upright brackets 26. The belt driving drums or sheaves of the rail units 22 are mounted on a cross shaft 27 which is journaled at its ends in the upstanding side brackets 26 and carries a sheave 28 connected by a drive belt 30 with an output sheave 31 on a motor reduction unit 32, the latter being supported on a top plate 33 on the end frame 16, which top plate 33 extends between spaced upright side plates 34.
The stack or pile supporting platform or table 13 (FIG- URES 2 to 4) comprises a series of rollers 35 supported on suitable shafts which are journaled at their ends in laterally spaced side frame members 36 and a center frame member 37. The table 13 may be provided with raising and lowering mechanism of either a mechanical or hydraulic type. A suitable arrangement for raising and lowering the table 13 is disclosed in my pending application Serial No. 692,319, led October 25, 1957, wherein the table is connected at its four corners to nut carrying bracket members which are mounted for vertical travel on upright driven screws. In the present apparatus the table elevating screws would be housed in the corner posts 38 and 40 on the end frames 15 and 16.
The apparatus is provided with a pair of longitudinally extending parallel side guide devices 41 and 42 (FIG- URES 1 to 9) which are identical except for being rights and lefts and which are mounted on the piler frame structure 12 in an identical manner. Only the side guide 41 and its mounting structure will be described, it being un- 4 derstood that the other side guide 42 is constructed and mounted on the machine in an identical manner.
The side guide 41 (FIGURES 5 to 7) is made up of a vertically disposed back plate 43 and an outwardly extending horizontally disposed reinforcing web plate 44 which is secured at its inner edge to the back plate 43 intermediate its top and bottom edges. A channel member 45 is secured with its open side against the lower portion of the inner face of the back plate 43, to form therewith a rectangular housing, with the web portion or inwardly directed face of the channel member 45 being in a vertical plane and forming a vertical guide face for engagement by the side edge of a sheet 10 when it is dropped by the conveyor 14. The channel member 45 is of a lesser height than the back plate 43 and the top portion of the guide is lled in by a curved plate section 46 forming a rounded top edge for guiding the edge of the sheet 10 towards the center of the apparatus.
The side guide 41 is supported at its opposite ends on carriage structures 47 and 48 (FIGURES 5 and 7) which are mounted in sliding relation on track forming cross members 49 and 50, respectively. The carriage structure 47 at the entrance end of the apparatus is slidably supported on a vertically disposed cross beam or track forming rail 49 which forms one vertical side of the cross frame housing structure 51 which extends across the end of the apparatus on the end frame 15. The carriage 47 (FIGURES 5 and 6) comprises a vertical plate 52 and a horizontally extending plate 53 secured intermediate the top and bottom edges of the outer face of the vertical plate 52 and extending towards the entrance end of the apparatus. The horizontal plate 53 carries on its bottom face a downwardly opening channel-shaped slide member 54 which straddles the top of the track forming cross rail 49. A bearing angle member 55 is secured at the bottom edge of the vertical plate 52 on the lower end of a vertical filler plate 56 and is positioned with its vertical leg riding against the inner face of the cross rail 49 and with its horizontal leg riding on the top of a horizontally disposed bottom plate 57 which is secured to the bottom edge of the cross rail 49. The bottom plate 57 extends outwardly and has at its outer edge an upstanding plate 58 arranged parallel with the cross rail 49 and spaced therefrom by an intermediate horizontal plate 5S to form with the cross rail 49 and the bottom plate 57 an upwardly opening housing in which an adjusting screw 60 is mounted.
The adjusting screw 60 (FIGURES 5 and 6) is suitably journaled in end plates 61 on the housing structure and is provided with right and left hand threads extending from the center thereof towards the ends. The screw 60 carries a nut 62 which is confined between the downwardly projecting axially spaced legs 63 of an inverted U-shaped saddle 64, the latter being secured to the bottom face of the horizontal plate 53 adjacent the slide 54 and extending into the housing 51, with the legs 63 cut out at their bottom edges to accommodate the screw 60. The adjusting screw 60 carries at one end a pulley 65 (FIGURE l) which is connected by a drive belt 66 with the output pulley of a motor reduction unit 67 supported on a cross frame plate member on the end frame 15.
The vertical plate 52 of the carriage 47 has a relatively narrow horizontal ilange forming plate 63 (FIG- URE 5) at its upper end on which the end of the side guide member 41 is adapted to rest. The side guide 41 is provided with a vertical end plate 69 and a horizontal base plate 70 which is bolted or otherwise secured on the plate 68 of the carriage. An equalizing shaft 71 is mounted in the guide 41 which is journaled in the end plate 69 and carries on its end a pinion 72 in operative engagement with a rack 73 mounted on the upper flange of an outwardly facing cross channel 74, which channel 74 extends across the end frame 15 above the housing 51.
The side guide 41 is supported at the other end of the apparatus on the carriage 48 (FIGURES 5 to 8) which comprises a downwardly opening channel-shaped slide or carriage member 75 having mounted therein a similarly shaped bearing slide 76 which straddles the track forming cross rail 50. The slide member 75 also carries a horizontally disposed keeper member 77 on the lower edge of its outer leg which has its inner edge extending into a guide slot 78 in the outer vertical face of the `cross rail 50. The slide member 75 has a pair of laterally spaced vertically extending plates 79 and 79 secured to its inner leg which are adapted to provide a slot formation 80. An angular end bracket 81 is secured on the end of the side guide 41 which has a horizontal leg 82 which is slotted at 83 to receive an upstanding pin 84 on the slide member 75, the pin 84 being provided with a washer 85 and a cotter pin 86, the latter being readily shearable upon substantial upward pressure being applied to the side guide structure 41. The top face of the slide member 75 is recessed at 87 to receive the top horizontal leg 82 of the bracket 81. The bracket S1 has a vertical leg S3 secured to the end plate 89 on the end of the side guide 41 which is provided with a vertically disposed outwardly extending plate member 90 which is adapted to be received in the slot 80 formed by the inwardly extending plates 79 and 79' on the carriage 48. The shaft 71 is journaled at this end of the guide 41 in the end plate 89 and carries a pinion 91 on its end which is in operative engagement with a rack 92 supported on the horizontal leg of an angle bracket 93 which is secured on the bottom of the cross rail 50.
The movement equalizing shaft 71 in the side guide 41 is supported intermediate the ends of the guide 41 on a center bearing (FIGURE 9) which comprises a vertically extending post 94 having its upper end curved to t the periphery of the shaft 71 and mounted at its lower end in a sleeve 96 which is secured in the bottom wall of the guide structure and which is provided with a bottom plug 97. The post 94 is keyed at 98 to the sleeve 96 and suitable oil passageways are provided with an oil plug 99 in the sleeve plug 97 to facilitate lubricating the mechanism. The support prevents sagging of the relatively long shaft 71.
The side guide 42 on the opposite side of the apparatus is arranged to cooperate with the side guide 41 and is carried on the cross rails or tracks -49 and 50 on carriages identical with the carriages 47 and 48 so that rotation of the screw 60 moves the side guides 41 and 42 toward and from the center of the machine. The side guides are held in parallel relation during their movement by the movement equalizing shafts and the rack and pinion connections at the ends of these shafts. The racks extend at their inner ends to the vertically disposed back stop 100 (FIGURES 2 and 4) so that the inner limit of movement of the side guides is approximately the side edges of the back stop plate 100.
With the arrangement described, the side guides 41 and 42 are carried on the track forming cross rails 49 and l50 so that any substantial upward pressure will merely lift the side guides, shearing the cotter pin 86 at one end and raising the saddle 64 at the other end. This avoids damages to the side guides and their operating mechanism in the event the operator carelessly raises the table 13 to too high a point where it strikes the side guides.
An end stop mechanism 101 (FIGURES l, 2 and l0 to 13) is provided which is mounted on the center unit 22 of the conveyor 14. The end stop mechanism 101 cornprises an elongate track forming housing 102 mounted in longitudinally extending relation on the center conveyor unit and a movable end stop carriage structure 103 which is slidably mounted on the housing 102. The end stop carriage structure 103 comprises a horizontally disposed support plate 104 which carries on its upper face a pair of upstanding parallel bearing brackets v105 and 105 between the upper ends of which there is pivotally mounted at 106 an air cylinder 107 having its piston 108 extending downwardly and connected at 109 to the free 6 end of an operating arm 110 which is mounted in the center `of a cross shaft 111, the latter having its ends journaled in upstanding bearing brackets 112 and 112' on the upper face of the support plate 104. A pair of relatively long, laterally spaced link members 1.13 and 113 are mounted near their upper ends on the cross shaft 111 and are pivotally connected at their upper ends by horizontal linkages 114 and 114 with the upper ends of a pair of parallel links 115 and 115', the latter in turn being secured on a cross shaft 116 which is journaled at its ends in upstanding bearing brackets 117 and 117' on the upper face of the support plate 104 at the opposite end thereof. The depending legs of the two pairs of links 113, 1.13 and 115, 11S are pivotally connected to the horizontal arms 118, 118i of a pair of L-shaped bracketV members 120, 120. The bracket members 120, 120 have on their vertical arms 121, 121 inwardly directed flanges 122 and 122 which are connected by a web plate 123 having at its center in vertically disposed alignment a pair of bearing ears 124 and 124.
The bearing ears 124 and 124' t between a pair of aligned vertically spaced mounting ears 125 and 125' which extend from thel center of the back face of the supporting or backing plate structure 126 for the bumper pad 127. A hinge pin 128 extends through the vertically aligned apertures in the bearing ears 124 and 124 and is secured in the mounting ears 125 and 125 on the backing plate 126 to pivotally connect the plate 126 to the web plate 123. A bracket member 130 extends from the upper ear 125 which is connected to the center portion of a tension spring 131, the latter having its ends secured to the bracket members 120 and 120', so that the bumper support plate 126 is pivotally mounted for swinging movement on a vertical axis on the web plate 123. The
. horizontal movement of the bumper plate is cushioned by the air cylinder 107 through the linkage 110, 113, 11S, 118 and 120.
The carriage 103 of the end stop mechanism comprises a downwardly facing channel-shaped slide member 132 (FIGURES l1 and 14) which is secured on the bottom face of the horizontal support plate 104 and which rests on the two laterally spaced track forming plates 133 and 133 on the top of the housing 102. The track plates 133, `133 have their longitudinal oppositely disposed or outside edges extending beyond the vertical faces of the two oppositely disposed channel members 134 and 134 which form the vertical sides of the housing 102. The edge flanges of the slide plate 132 are provided with keeper plates 135 and 135 for retaining the slide 132 on the track plates 133 and 133.
The slide plate 1132 has attached along the center of its bottom face a depending bracket or cage structure 136 which has a neck portion 137 extending downwardly between the track plates 133 and 133 and a cage forming portion comprising top and bottom plates 13S and 138 with axially spaced end plates 140 and 140 which are bored to accommodate the adjusting shaft or screw 142 which is supported in the housing 102. The screw 142 carries a nut 143 which fits between the end plates 140 and of the cage 136 so that rotation of the screw imparts axial movement to the nut 143 and the cage 136 and causes the carriage 103 to travel on the housing 102.
The screw 142 is journaled at its opposite ends in the ends of the elongate housing 102 and at one end thereof carries a sprocket 144 (FIGURE 2) which is connected by the drive chain 145 with the output sprocket 146 on a drive motor unit 147 mounted by a suitable bracket plate on the top of the end of the housing 102.
The housing 102 and the `adjusting screw 142 are provided with a slidable center support or brace mechanism (FIGURE 14) which comprises the axially spaced end block members 148 and 148 and a pair of connecting rods 149 and 149', the latter being secured at opposite ends to the block members 14S and 148'. The block members 148 and 148 which are spaced apart a distance approximately half the length of the housing 102 are formed with axial bores which accommodate the screw 142 and are constructed so that the members 143 and 148 will slide freely within the housing 102. The carriage 103 is mounted initially on the housing 192 with the depending cage structure 136 and the associated nut 143 in the space between the two block members 14S and 148 of the sliding brace mechanism, With this arrangement when the carriage 103 is moved in one direction along the housing 102 by operation of the screw 142 the cage 136 will engage the block member 148 and carry `the same towards one end of the housing 102. When the carriage 103 moves in the opposite direction by rotation of the screw 142, the cage 136 will engage with the opposite block member 148 and carry the center brace members towards the other end of the housing 102 so that regardless of the position of the carriage 103 the screw 142 is supported intermediate its ends with the maximum unsupported distance being the distance between the two members 14S and 148'. This arrangement prevents sag in the adjusting screw 142.
With the end stop mechanism 101 being mounted on the carriage 103 which is slidably supported on the longitudinally extending housing 102 and connected to the traveling nut 143 on the adjusting screw or shaft 142 the position of the end stop 127 may be readily and quickly adjusted at any time without stopping the piling conveyor.
While particular materials and specific details of construction have been referred to in describing the form of the apparatus illustrated, it will be understood that other materials and equivalent structural details may be resorted to within the spirit of the invention.
