10 Claims.

The present invention relates to rolling mills and particularly to av system thereof for handling made-up coils orbundles as they are beingA delivered at short intervals from a group of bundle coilers that receive, coil-bundle and deliver the hot rolled output from the rolls.

A further purpose is to pull the bundles along a slideway by the successive dogs of a conveyer and to speed up each bundle to unloading arms having an angularly movable bed, the bed in its bundle receiving position sloping downwardly fromthe discharge drums, and to angularly reciprocate the bed upending, and retracting it, during periods intermediate its recept of successive bundles from the drums for charging the successive bundles upon the preferably horizontal receiving arms of a` carrier.

A further purpose is to use each dog of a conveyer first to pull abundle along the slideway to a discharge drum and then to limit the forward movement oi the bundle as it slides forward to the inclined receiving vbed of an unloadingr device.

A further purpose-is to locate the axis of a four-armed bundle carrier and theline 0f travel of bundles to thefcarrier in a common vertical plane.

A furtherpurpose is to use a common drive for a conveyer and for unloading drums receiving and unloading bundles from said conveyer.

A further purpose is to provide a swinging .frame which receives bundles, oneat a time and to unload them upon a transfer mechanism through an intervening pusher pivoted to the arm.

A further purpose is to'coordinate the operations of thesecondconveyer, of a bundle unloader and of a bundle carrier, using the conveyer to deliver the bundles one at a time to the unloader for one-at-a-time delivery to the carrier. Preferably the conveyer, unloader, and carrier are operated by meansof individual limit switch motors, associatingthe starting switches of the unloader andcarrier motors respectively with the stop switches of the conveyer and unloader motors.

A further purpose is to provide novel and efficient mechanism for transferring a succession of bundles from a rolling-mill conveyer to an arm of bundle carrier-for subsequent presentation to bundle transfer mechanism.

Further purposes will appear in the specication and in the claims.

My invention relates not only to the mechanism involved but to methods by which this and 55 tion and referring to other mechanism may be operated to carry out the invention.

Describing in illustration andnot'in limitathe drawings:

It will be understood that the hot rolled products from a plurality of rolls, not shown, deliver to any of a number o bundle-coilers in positions Hi, il and I8, Figure la, and that neither the rolls nor the bundle-coilers are themselves the object of the present invention.

The` bundle-coilers may be of any suitable number and be located side by side'. They are intended to be shown here conventionally only, and as four in number.

Each bundle-coile1` includes a vertically'movable stripper spider |9, 20, 2|, 22 above which each bundle or

coil

23, 24, 25, 25 is wound between inside and outside fingers 21 and 23. The fingers 21 and 23 of each coiler extend upwardly from and form a portion of an intermittently movable rotor 29, Sil, 3|, 32 individual to that coiler. In each position the corresponding rotor is stopped after winding a coil and the stripper spider I9, 25, 2| or 22 is then moved vertically upwardly to present the freshly wound coil high enough to clear the ngers and in front of one of a group of

discharge plungers

33, 34, 35 and 35.

The invention does not reside in the coilers nor in the mechanism by which the coils are discharged. The discharge plungers are operated in any suitable way by a motor not shown. The coils are hollow and are discharged as in the prior art, being deposited upon the receivingI or input end of a slideway 4|, extending longitudinally in the direction of feed. They are progressed on the slideway by a first conveyer 42, which carries them into position where their forward interior surfaces are engaged by the dogs of a second conveyer.

The bundles of the various groups upon the slideway are carried meantime by a second conveyer 43, preferably an intermittently continuous conveyer, through successive intermediate positions to the voutput unloading (discharge) end of the slideway. Here they are fed, one at a time to speed pick-up slideway unloader drums 44, 45, which act effectively as a unit.

At the slideway discharge point an unloader 46 pushes the bundles one at a time upon one of the

arms

4l, 4B, 49, 50 of a bundle holder or carrier 5|. It is shown as of four-arm turnstile type. The bundle holder or carrier 5| moves intermittently to present its receiving

arms

4T, 48, 49 and 5|) successively to the bundle receiving position. As soon as one arm is filled another is presented to receive bundles. In receiving position these arms lie in the vertical plane of the second conveyer.

The slideway for convenience is located over a pit 52 within the foundation walls 53. These walls, along with piers 54, posts 55 and beams 55, 5'! provide supports 58, for the two

conveyers

42, 43; and

foundations

59, 50, El and B21, for conveyer sprocket support; S3 and 64 for conveyer driving and timing mechanisms; 65 for the bundle holder 5|; 65 for the driving and timing devices for the bundle holder; and 61 for the means for tilting unloader 45.

The bundles are advanced bythe first conveyer by pushing for a reason which will later appear. This pushing is accomplished by dogs 63, upon links 69 of the first conveyer 42 comprising a pair of chains l0, 1| which operate about sprocket wheels l2, 13 upon a shaft 14 in bearings l5, 1S, and about sprocket wheels Tl, 18 mounted upon a shaft 19 in bearings 88, 8|. Either pair of sprocket wheels may be drivers and the other pair driven or idlers. As illustrated 12 and 13 are the drivers. The dogs operate in

parallel slots

82, 83 oppositely olset in the slideway.

Because the rst conveyer 42 shoves or pushes the bundles from the rear of each bundle, it advances the bundles beyond the forward end of this conveyer. This gives each bundle enough of a lead at this point so that it can be engaged conveniently by one of the prongs 84 of the second conveyer 43 which enters within the interior space of the bundle. This takes place as a link 85 carrying the prongis carried by its chain SS about one of its sprocket wheels 8l upon shaft 88 in bearings 39, S0.

The chain of this second (in this case preferably the puller type of chain conveyer 43 passes about a second sprocket wheel Si rigidly mounted on a shaft |69 in

bearings

92, 93. As in the case of the rst conveyer, either sprocket wheel may be the driver.

The top and bottom stretches of the two conveyers are supported appropriately at 94, and 96. Si. At an intermediate point QS in the travel of the second conveyer the slideway is narrowed, giving access to the bundles for inspection and facilitating here the removal of bundles where this is desired. i

The operations of each of the different motors may be controlled by hand switches so as to be operatively separate with or without the use of limit switches or the controls which they exert over the operation of other parts of the system. This applies not only to both conveyers but also to the unloading arms and to rotation of the carrier or holder shown of turnstile type. The bundles are delivered upon the slideway in front of a dog 68.

The first conveyer is relatively short and progresses the bundles to a position where each in turn will be picked up by one of the dogs oi the second conveyer.

The speed of the entire system will normally be dictated by the speed of supply from the mill and, intermediately, by the speed of the coiling (bundling) mechanisms and their number.

The rst conveyer is operated at a speed which will deliver each bundle in time to be picked up by the second conveyer.

The second conveyer may preferably operate intermittently because it is dependent upon the supply of bundles from the ceiling mechanisms.

As a preferred means of operating I run the first and second conveyers by separate motors 99, |09, of limit switch type having suitable limit switches IUI, |02, connecting gearing |93, |94

and bearings IE5, |05. In order to emphasize the fact that the individual conveyers-as well as the other mechanism describedcan be actuated independently I show hand operated starting switches |91, |08 in the circuits of these two motors.

It is desirable to interlink the various mechanisms so as to continue the operation successively after it shall have been started.

One suggested way for operating, applied to operation of the second conveyer, is to have final operation of the bundle lift at coiler position close the circuit of the motor operating the lateral loading mechanism to transfer a bundle to the rst conveyer. This at the start opens the circuits of the motors oi' both conveyers. Retraction of the plunger for the lateral loading closes the circuits of both conveyers. If the second conveyer controls the rst, it would not be necessary for this plunger movement to opennor then to close-the circuit of the first conveyer.

The limit switch |02l of the second conveyer may not only control the secon-d -conveyer as above so as to causefit to stop after bundle has. been advanced into position for-engagement by the second conveyer, but may also regulate the first conveyer and of the unloading arms.

In proper sequence for discharge of bundles from the second conveyer, the second conveyer will stop after feeding a bundle and it will remain stopped and the first conveyer will consequently remain stopped until the bundle loading mechanism shall have reciprocated, loading another bundle.

'Iurning of the bundle carrying arms upon which the bundles are placed by the unloaderA may also be controlled by a limit switch |02 but preferably is controlled through the limit switch of the mechanism which throws the unloader arms, In either event the intention is after one arm shall have been filled to have the receiving arms revolve a quarter turn prior to the placing of a succeeding bundle upon a newly presented holder arm.

Shaft I 09 carrying sprocket 9| carries also pick up

drums

44 and 45 which serve several purposes. They are spaced at I| and from adjacent parts and are larger in diameter than the body of the sprocket wheel. The bundles are carried up upon their surfaces ||2 by the second conveyer, relieving the bundles of a part at first and then of all of the friction against the slideway.

Through back gearing hereinafter described the pick up drums are given a peripheral speed considerably greater than the lineal speed of the second conveyer, with the result that as soon as the bundles have been pushed up upon the pick up drums far enough for the pick up drums to take over the progression of the individual bundles, each bundle in turn is drawn ahead more rapidly than moves the particular dog of the second conveyer which previously has been dragging the bundle. This relieves the bundles from engagement with the dog and permits the dog to be carried by its link about the adjacent cirumference by the sprocket wheel 9| without rubbing the dog against the interior surface of the bundle.

The structure is stiffened by braces ||3, |I4 between the end of the slideway and the support.

In the meantime the bundle is carried by the surfaces of the drums and is thus tilted and discharged so that its forward end slides down against a bumper I 5 at the lower end of unloading arms 45. As illustrated the upper part of the bundle rests upon the surfaces of the pick up drums until-which should be immediately after-the unloading arms 46 start their swing toward one of the turnstile arms.

As the pick up rolls tilt the bundle down against the bumper |I5 there need be-and in the illustration is-no engagement between the bundle and the upper ends of the unloader arms nor with the segmental faces of the pushers. Friction of pick-up rolls with the bundle is then avoided by timing which immediately swings the unloading arms 46 upward and to the left so as to first engage the bundle from the right and beneath and to lift the bundle away from the pick-uprolls. The weight of the bundle is taken at the start by the swinging, unloading arms 46 and partly by the bumper. As the bundle reaches approximately vertical position ythe weight is a1- most all transferred to the bumper and withvsubsequent movement of the arms 46 and the push-` `shaft ||8 is gear ers the bundle is transferred to one of the arms 41-50.- A succeeding bundle when placed upon the Asamearm must push the next and any additional bundles already on Vthe arm to before the bundle which is being mounted can be transferred. The unloading arms 46 then return to the position shown in dotted lines in Figure 3 to receive the next bundle.

Mechanism by which the peripheral speed of the pick-up drums may be stepped up above that of the chain advance is seen in Figure 7, in which at the upper end of the figure back gearing is provided suitable for effecting the stepping up of the speed.

The shaft |09 carries a gear IIS which meshes with the gear I|1 upon a back gearing shaft IIB turning in bearings ||9 and |20. Rigid with `I2| which meshes with a gear I22 rigidly connected to the drum 44 and with the drum 44 freely turning on the shaft |09 coaxial with gear |I6. Gear I22 is keyed to a hub extension from the drum 44, opposite hub extensions of the drum turning freely on the shaft |09. Intermediate bearing metal is shown in ring |24.

Because the gear ||6 is much largerthan the gear |22 and the gear I1 ismuch smaller than the gear |2|,'there is considerable increase of speed by the back gearing shown,` the increase of speed being proportionate to the differences in the diameters in these respective pairs of gears.

The back gearing shaft I I8, at the opposite end from that which carries gears I1 and IZI, carries gear |25of the same size as gear I2! and it drives gear |26 "mounted rigidly upon one of the hub extensions |21 of the pick-up drum 45 which turns freely on the shaft I 09. It will be seen that the pick-up drums, on opposite sides of the sprocket 9|, operate effectively as a unit. Bearing metal |28 may be used if desired between the hubs |21 and the shaft |09.

The unloading mechanism appears in Figures 1, 2, 3, 4, 'and 6.

The arms 46 are duplicates. They are rigidly mounted on a shaft |29 and with theshaft tilt between some such positions as are shownY in ciprocating the shaft, operating through crank arm |3|, pin |32, connecting rod |33, pin |34, and rocker arm rigidly mounted on the shaft |29. Any suitable mechanism connects the rocker arm and unloading arms 45. As shown, both are intended to be rigidly attached to the shaft |29.4 Y

The bumper ||5 v-is adjustable along the length of the unloading arm by the interposition between it and-the bracket I 36' of a variant quantity of lagging |31 according to the diameter of in Figure 3, the interior of the bundle will t over the nose |33 'of that turnstile arm 41`50 upon vwhich the bundles are being placed, without undue friction in placing the bundle.

With the front faces upon the appropriate arm so that further swinging movement of the unloading arms te the left The exactpoint l'to which the bundle will come and the question of whether the inside ofthe bundle shall be level with the top of the carrier arm when the engagement with this arm takes place will be subject to variation according to the wishes and policy of the user and obviously can be varied for the same size of the bundle 5 by altering the lagging and can be made to suit different sizes of bundles by the same means, lifting the interior of the bundle to any predetermined height along the length of the unloading arms.

The unloading arms are in Figures l and 5 and in side elevation 2, 3, and 6.

Each unloading arm notv only itself swings but carries at its outer end a pivoted pusher shoe, 1 the two pusher shoes being alike. The unloading arms 45 at the upper ends are extended diagonally upward and rearward to give position for shafts |40 upon which the pusher shoes are pivoted. Each pusher comprises, as illustrated, side frame members |4| joined across the end by a cylindrical pusher wall |42, forming a sector which presents an arc shaped pusher face at |43. The center of the arc is the axis of the pivot shaft |40;

Each pusher face is adapted to engage with the rear face of a bundle which is being handled and to push the bundle to the left and upwardly as the arm 46 swings. The pivotal engagement of the pusher permits the sector to swing so thatV there is rolling engagement only between 'the pusher face and the rear of the bundle. l

The sectorial pushers are shown in cross-section in Figure 4 and in side elevation in Figures 3 and 3c. ln Figure 4 fragmentary portions of the pick-up drums appear to the right and left and the sprocket wheel with its chain is located in the center within protecting walls |44, |45, spaced at |45. The sectorial pushers lie between these walls and the pick-up drums. Their pivot shafts or pins turn within bushings |41, |48 supported by the walls of bores |49, |50 in the hubs of the respective arms 45. Continuations |5|, |52 of the arms carry stops |53 reinforced by rims |54. The stops limit the outward swing of the pushers by end walls |55. Inward swing is restricted by shoulders |55, one upon each arm. Laterally adjacent stops |53 are facing ribs |51, |51 which normally perform no function but which afford support against excessive lateral thrust upon the pushers.

The rotary carrier or holder 5| is supported by bearings |11 and is held against tilting movement by lateral bearing |12. A

The switch interlinkage between the second conveyer and the unloading arms must be such that the arms lie back in receiving position at the time the second conveyer delivers its foremost bundle upon the pick-up

drums

44 and 45 that in turn tilt the bundle to and deliver it upon the unloading arms 45.

If the unloading arms be not immediately engaged by the bundle except at the lower end of the bundle adjacent the bumper, it is quite deshown in top plan View in Figures sirable that the unloading arms be tilted as soon after the bundle has been placed upon them as possible in order to avoid rubbing friction between the pick-up drums and the bundle.

One of the carrier or holder arms must be opposite the bundle at the time the unloading arms act. They place each bundle in turn upon the end of a carrier arm and each `as placed is effective to shove any bundles already on the carrier arm further back upon the arm, up to the time when this carrier arm holds its intended full load.

The timing and switch -connection are such that when the last unloading arm movement takes place, and after the unloader arms have retracted, the carrier or holder is rotated by rotation of gear |58 to a distance sufficient to bring an empty -arm in position to receive the succeeding bundles; and one carrier or holder arm at a time is filled or partially 'lled with bundles and turned to position for discharge of these bundles as another empty carrier or holder arm is brought to position.

The linkage may be direct cr not. For example, the successive operations of the unloader arms and carrier or holder arms need not be linked up with the closest moving parts but in some cases can be operated by some other member within the train of operation.

It will be evident 'that the use of pushing prongs on the rst conveyer permits the bundles to be shoved far enough ahead of the first conveyer so that the second conveyer may have room to turn and to raise its prongs into the spaces within the bundles, v

It will further be evident that stoppage of the rst conveyer with its forward prongs near or at the end of its pushing stroke but before their chains have begun to turn about their sprocket wheels, with subsequent removal of the bundle by the second ccnveyer from contact by the first, avoids scraping of the first conveyer prongs against 'the rear faces of the bundles when these prongs do turn with their `chains about their sprocket wheels. The use of the pick-up rolls at the unloading positionlperforms a corresponding function for the second conveyor, carrying the bundles out of contact ywith the second conveyer prongs before these second conveyer prongs have begun to turn about their sprocket wheels adjacent the pick-up rolls.

It will be evident that the turning of the carrier arms can take place while the

unloader arms

44 and 45 are retracted or partly retracted but that if the number of `bundles to a carrier arm corresponds with the number of bundles loaded at a time and the second conveyer be stopped for loading, plenty of time can be provided for this carrier armm'ovement during the stoppage of the second conveyer.

It will be evident that the turnstile type of vcarrier construction is quite convenient and effective but that other types of carrier construction could be used with part of the advantage of my construction.

It will be evident that friction against vthe bundle can be reduced greatly by exact timing of the delivery from the pick-up rolls and the operation of the unloading arms. This is accomplished by having 'the ypick-up rolls tilt the bundles free from initial Contact with the upper parts of the unloading arms but into contact with the bumper on the unloader and just as these unloader arms tilt to lift the bundle away from the pick-up rolls. By this timing sliding of the bundle along the length of the unloader arms is avoided and at the same time the ybundle is lifted from the pick-up rolls in time .to relieve from rubbing of the under surface of the bundle by lthese rolls.

As seen in Figure 2, the foremost prong upon th'e second conveyer may be used to prevent the bundle from moving unduly in a lateral direction as it tilts on the pick-up rolls. It may also act as a catch, engaging the inner rear bundle surlface to take part of the jar which would other- Wise be taken upon the bumper vor all of the jar of the tilted bundle (Figure 2).

The pivotal connection of the pushers upon the unloader arms prevents sliding friction of the pushers against the faces of the bundles as the bundles are transferred to the carrier arms and at the same time are lifted by the Wedge action of the sloping ends of the carrier arms as the bundles are forced upon these arms.

It will be evident that hand switches in all of these motor circuits permit individual operation of these circuits either-using the hand switches alone for control of the circuits or providing the hand switches as ultimate control, to prevent operation when the .individual hand switches are open. Where the hand switches 'are used for the entire control of the circuits they not only permit alteration of the sequence of the operation, to use one of the motors out of turn but a longer time than would be the automatic control described.

In view of my invention and disclosure variations and modiiications to meet individual whim or particular need wil-l to others skilled in the art, to obtain 'all or part of the benefits of my invention Awithout copying the structure shown, and I, therefore, claim all such in so far as *they fall Within the reasonable spirit and scope of my invention.
