- the purpose of guide member 62 is to cooperate with wall 60 in controlling the random deposit of rings 16 on table 56 so as to provide a completed coil of the desired dimension. More particularly, as each ring drops, it will be engaged by one edge 64 of guide member 62. By properly controlling the distance between edge 64 and the adjacent inner cylindrical surface of wall member 60, the radial thickness of the coil being produced will be controlled.
- Guide member 62 is actuated by a double acting cylinder 68 which acts to drive piston 70 down and up as required. Member 62 is guided during this vertical travel by grooved rollers 72'which roll on fixed vertical guide posts 74.
- the coil 66 accumulating on coil collecting table 56 has achieved the proper size, it is cleared from the apparatus by first lowering guide member 62 into well 76 through suitable actuation of cylinder 68.

- the pusher arm 78 is actuated by means of a motor 84 acting through a shaft 85 and gear box 86 to cause a single revolution of crank arm 87. This in turn results in the lever 88 mounted on swing links 90 being pulled from I the position of FIG. 1 to that of FIG. 11.
- Lever 88 is connected to pusher arm '78, the latter having on its end a vertical plate 92 which moves through a slot in wall member 60 to contact and move completed coils on coil collecting table 56 out through opening onto conveyor 82. Once this has been accomplished, the pusher arm is retracted and the guide member 62 raised to its operative position. The apparatus is then again ready to resume formation of another coil on coil collecting table 56.
- An intermediate support plate is shown at lying in a plane spaced vertically above the top of guide member 62.

- the second and more complicated circumstance during which use of support plate 100 is required occurs when the completed coil on coil collecting table 56 weighs less than the billet originally introduced into the mill. Where this is the case, the completed coil must first be divided from the rod continuing to issue from the mill by advancement of support plate 100. Once this has been accomplished, a shearing operation is then carried out to separate the coil from rings piling up on the plate. However, if the weight of plate 100 precludes fast movement across the path of the continuously descending rings, several rings may be pushed into the jaws of the shear 114 located on one side of wall member 60. Should this occur, the shear may be jammed.
- the present invention content plates the positioning of a plurality of fast acting cylinders 116 spaced around the circumference of wall member 60 at a level slightly above that of the intermediate support plate 100.
- Each cylinder 116 is provided with a piston rod 118 connected by means of a laterally extending bracket 120 to a relatively small diameter retaining pin 122 which is in turn slidably contained within an adjacent cylindrical housing 124.
- the pins 122 By extending piston rods 118, the pins 122 will be placed in the retracted position as indicated in FIG. 2. However, by retracting piston rods 118,.each pin 122 will be axially advanced through appropriately positioned apertures in wall member 60 to operative positions indicated at 122a extending across the path of the descending rod rings 16. In this manner,
- FIGS. 3 to 7 wherein this sequence of operation is illustrated diagrammatically.
- the intermediate support plate 100 and the retaining pins 122 are in the withdrawn position, thus allowing rod rings 16 to descend in a helical fashion over guide member 62 where they are eventually collected in a growing coil 66 on table 56.
- coil 66 has attained the desired weight
- cylinders 1'16 are actuated to retract piston rods 118 and thus advance retaining pins 122 to operative positions extending across the path of the descending rings 16 as indicated at 122a in FIGS. 5 and 6. Thereafter, rings begin to accumulate on the advanced pins as at 126.
- FIG. 3 and 4 the intermediate support plate 100 and the retaining pins 122 are in the withdrawn position, thus allowing rod rings 16 to descend in a helical fashion over guide member 62 where they are eventually collected in a growing coil 66 on table 56.
- cylinders 1'16 are actuated to retract piston rods 118 and thus advance retaining pins 122 to operative
- the rings at 126 are now connected to the completed coil 66 by a single strand 128 which spirals downwardly across the path of support plate 100.
- Support plate 100 is then advanced to its operative position as shown in FIG. 7 by actuation of cylinder 106, thus carrying strand 128 to the right towards the general vicinity of shear 114.
- the cylinders 116 are again actuated to retract retaining pins 122 and thus allow the rings temporarily supported thereon at 126 to drop onto plate 100 where they will remain until the completed coil 66 has been cleared from coil collecting table 56.
- a strand positioning device 130 is provided to positively carry strand 128 directly into the jaws of shear 114.
- strand positioning device 130 is comprised of a positioning arm 132 mounted for pivotal movement about point 134.
- the positioning arm is provided with a curved edge 136 corresponding to the curvature of wall member 60 which edge terminates at one end in a somewhat hook-shaped attachment 138 which is provided with a strand retaining recess as at 140.
- the positioning arm 132 is positioned adjacent a slot 142 in wall member 60 which slot is substantially closed by curved edge 136 when the arm is in its inoperative position as shown in FIG. 2. In this manner, the possibility of a rod leading end becoming inadvertently lodged in slot 142 as rod is fed into the apparatus is elfectively avoided.
- Positioning arm 132 is pivoted about point 134 by means of a double acting cylinder 144 provided with a piston rod 146 which is pivotally connected to the arm as at 148.
- cylinder 144 is again actuated to extend piston rod 146 and thus pivot arm 1'32 in a clockwise direction about point 134 to its inoperative position as shown in FIG. 2.
- the curved edge 136 of arm 132 will again close slot 142 and thus effectively eject any rod portion which might have been drawn into the slot during the shearing operation.
- the completed coil 66 is then cleared from the coil collecting table 56 in the manner previously described by lowering guide member 62 and actuating pusher arm 78.

Woodrow, Worcester, Mass., assignors to Morgan Construction Company, Worcester, Mass., a corporation of Massachusetts Filed Sept. 29, 1965, Ser. No. 491,369 8 Claims. (Cl. 29-200) This invention relates generally to the metal working industry and more particularly to an improved apparatus for collecting and dividing hot rolled steel rod into bundles or coils.
Recent developments in the art of rolling steel rod have shown that significant advantages may be obtained by cooling the rod at a controlled rate in direct sequence with the rolling operation prior to forming the rod into coils. The concept is fully disclosed in US. patent application Ser. No. 402,495, now Patent No. 3,231,432, granted Jan. 25, 1966, wherein it is shown that the rod may be initially deposited on a moving conveyor in a continuous series of overlapping non-concentric rings. The conveyor is suitably designed to permit rod cooling at a controlled rate to achieve substantially uniform predetermined metallurgical properties over the entire length of the rod. Once the rod has been cooled in the desired manner, it is taken from the delivery end of the conveyor and thereafter formed into coils of preselected weight.
A coil forming apparatus which has heretofore been designed to receive cooled rod from a conveyor of the above mentioned type is described in U.S. Patent No. 3,176,385. The construction of this apparatus is such that after one coil had been formed on an underlying collecting table, the initial rings of the next coil will be collected for a short time by a temporary support plate which is adapted to be advanced to an operative position overlying the completed coil. As soon as the collecting table has been cleared of the first completed coil, the temporary support plate is withdrawn, thus permitting the rings accumulated thereon to fall by gravity to the collecting table where the coiling operation is continued. Although the above-described apparatus had proved generally satisfactory in operation, experience new indicates that under certain circumstances where the support plate must of necessity be made of a heavier construction, it may not be possible due to increased inertia to advance the plate to its operative position overlying the completed coil with suflicient speed to avoid damaging contact with the descending rod rings of the next coil. This is primarily because a heavier support plate cannot undergo rapid acceleration followed by sudden deceleration without damaging other components such as the cylinders used to advance and retract the plate. It is therefore an object of the present invention to provide means for temporarily arresting the downward descent of rod rings for a brief period during which the support plate may be advanced at a slower rate to its operative position overlying the completed coil.
This is accomplished by providing a plurality of relatively small diameter fast-acting retaining pins arranged in a radially disposed manner surrounding the path of descent of the rod rings at a level slightly above that of the support plate. When advanced to their inwardly extending operative positions, the pins prevent further descent of rod rings across the path of the support plate, thus permitting the plate to be advanced to its operative position at a slower rate. Because of the fast operation of the pins which is in turn made possible by their relatively light-weight construction, any damage to the descending rod rings which might otherwsie be caused by contact with the slower moving heavy support plate is effectively obviated. Moreover, by advancing the support plate at a slower rate, damage to the means utilized for advancing and retracting the plate is prevented by avoiding rapid deceleration. With the support plate safely advanced, the retaining pins are immediately withdrawn to allow rod rings of the next coil to temporarily accumulate thereon while the underlying coil collecting table is cleared of the completed coil.
It should also be noted that under certain operating conditions where the weight of a billet originally introduced into the mill exceeds that of the coils being formed, provisions must also be made for separating each completed coil from the continuous length of rod being rolled. For example, if rod is being rolled from a 1200 pound billet, it might be desirable to collect the rolled rod into four coils of 300 pounds each. Under such conditions, after the support plate had been advanced to its operative position, the underlying completed coil will be connected to the rings of the next coil being tem porarily deposited on the plate by a single strand. Means must therefore be provided for shearing this strand prior to clearing the completed coil from the coil collecting table. It is heretofore been proposed that this strand be carried into the operative range of a suitably positioned shear by the forward edge of the support plate. It is a further object of the present invention to improve this arrangement by providing additional means operating in conjunction with the forward edge of the support plate for positively carrying the rod strand directly into the jaws of the shear. In this manner, effective separation of the completed coil on the coil collecting table from the rings of the next coil being collected on the support plate will always be assured prior to removal of the completed coil from the apparatus.
These and other objects of the present invention will become more apparent as the description proceeds with the aid of the accompanying drawings in which:

FIG. 2 is a horizontal sectional view on an enlarged scale taken along line 22 of'FIG. 1;

' FIG. 5 is a view similar to FIG. 3 with the retaining pins advanced to their operative position;
FIG. 6 is a vertical sectional view taken along line 66 of FIG. 5;
FIG. 7 is a vertical sectional view similar to FIG. 6 showing the support plate fully advanced and the retaining pins withdrawn;
FIG. 8 is a horizontal sectional view taken along line 8-8 of FIG. 7 showing the strand positioning arm being pivotally advanced beneath the support plate;
FIG. 9 is a view similar to FIG. 8 showing the movement of the strand positioning arm in relation to the rod strand connecting the completed coil on the coil collecting table to the rod rings temporarily being accumulated on the support table;
nism activated to move the completed coil onto an adjacent conveyor.
Referring initially to FIGS. 1 and 2 wherein are best shown general features of the invention, there is provided a steadily moving conveyor generally indicated at comprising a driven chain 12 having a series of upwardly extending teeth 14 of such height that they will effectively engage non-concentric overlapping rod rings 16 being carried by the conveyor. It is to be understood that the rod rings 16 have previously been deposited on the opposite end of the conveyor by a laying head (not shown). The rod rings receive support from conveying chains 18 and stationary tracks 20 with together provide adequate support for the rings so that sagging will be prevented without adversely affecting the desired exposure of the rings to the cooling medium.
A supporting structure generally indicated at 22 in cludes' suitably spaced uprights 24 and 26 on either side of the conveyor 10, which uprights in turn carry transverse beams 28 and 30. Beam 28 has secured thereto a bearing support 32 carrying a transverse shaft to which are afiixed sprockets for chains 12 and 18. In addition, transverse beams 28 and support a tractor chain assembly generally indicated by the reference numeral 36. The tractor chain assembly includes two endless chains 38 and 40 carried by sprockets 42 beneath a protective hood 44. The lower chain 40 is driven by conventional means (not shown) and the upper chain 38 is urged downwardly into contact with the lower chain 40 by means of springs 46 on either side of the conveyor 10. The springs 46 act through rods 48 and pivotal arms 50 mounted on upstanding supports 52 extending upwardly from transverse beam 28.
As the rod rings leave conveyor 10, they are gripped betweentractor chains 38 and 42 which in the usual case are driven at a speed slightly greater than that of the conveyor. This results in the rings being accelerated while being held in substantially horizontal plane until finally released from engagement by the tractor chain unit 36 as indicated by rings 16a. Thereafter as gravity becomes effective, the falling rings 16 stretch into a helical arrangement as indicatde generally at 54 in FIG. 1 until they are deposited at random on an underlying coil collecting table 56.
In order that the rings 16 may be properly guided in their downward travel to coil collecting table 56, the apparauts is further provided with a generally cylindrical .wall member 60 and a vertically movable interior guide member 62. The purpose of guide member 62 is to cooperate with wall 60 in controlling the random deposit of rings 16 on table 56 so as to provide a completed coil of the desired dimension. More particularly, as each ring drops, it will be engaged by one edge 64 of guide member 62. By properly controlling the distance between edge 64 and the adjacent inner cylindrical surface of wall member 60, the radial thickness of the coil being produced will be controlled.
An intermediate support plate is shown at lying in a plane spaced vertically above the top of guide member 62. The support plate is provided with wheels 102 arranged to run along horizontal support tracks 104 extending in parallel relationship along opposite side of cylindrical wall member 60. The piston rod 105 of a double acting cylinder 106 is pivotally attached to the rear edge of plate 100 as at 108 to thus provide a means of advancing plate 100 along tracks 104 to an operative position as shown in FIG. 11 overlying coil collecting table 56 and thereafter, to withdraw the plate back to its inoperative position as shown in FIGS. 1 and 2.
As can be best seen in FIG. 11, advancement of the support plate 100 to its operative position overlying coil collecting table 56 will result in the interior of cylindrical wall member 60 being divided into upper and lower chambers 110a and 11%. Once this has been accomplished, any rod rings subsequently issuing from tractor chain assembly 36 will be temporarily collected in chamber 110a on the upper surface of the plate as at 112, thus allowing sufficient time for the lower chamber 11017 to be cleared of the completed coil.
As previously mentioned during normal operation of the apparatus there are two different circumstances which will require advancement of plate 100 to its operative position. First, there is the situation where the weight of the coil being formed is equal to that of the billet being rolled by the mill. Where this is the case, support plate 100 will be advanced after all of the rod rings formed from one billet have been deposited in coil form on coil collecting table 56 and prior to the arrival of rings from the next billet. This is by far the simplest situation since the normal interval between billets provides ample time for the plate to be advanced to its operative position without contacting a continuous series of descending rings. Moreover, since all of the rings from one billet are formed into a single coil, there is no need for a shearing operation prior to removing the completed cell from the apparatus. I
The second and more complicated circumstance during which use of support plate 100 is required occurs when the completed coil on coil collecting table 56 weighs less than the billet originally introduced into the mill. Where this is the case, the completed coil must first be divided from the rod continuing to issue from the mill by advancement of support plate 100. Once this has been accomplished, a shearing operation is then carried out to separate the coil from rings piling up on the plate. However, if the weight of plate 100 precludes fast movement across the path of the continuously descending rings, several rings may be pushed into the jaws of the shear 114 located on one side of wall member 60. Should this occur, the shear may be jammed.
To avoid this difficu'lty, the present invention content plates the positioning of a plurality of fast acting cylinders 116 spaced around the circumference of wall member 60 at a level slightly above that of the intermediate support plate 100. Each cylinder 116 is provided with a piston rod 118 connected by means of a laterally extending bracket 120 to a relatively small diameter retaining pin 122 which is in turn slidably contained within an adjacent cylindrical housing 124. By extending piston rods 118, the pins 122 will be placed in the retracted position as indicated in FIG. 2. However, by retracting piston rods 118,.each pin 122 will be axially advanced through appropriately positioned apertures in wall member 60 to operative positions indicated at 122a extending across the path of the descending rod rings 16. In this manner,
further descent of rod rings across the path of advancing plate 100 will be temporarily prevented and the danger of the plate engaging a number of rings thus avoided.
To further illustrate the above, reference will now be made to FIGS. 3 to 7 wherein this sequence of operation is illustrated diagrammatically. In FIGS. 3 and 4, the intermediate support plate 100 and the retaining pins 122 are in the withdrawn position, thus allowing rod rings 16 to descend in a helical fashion over guide member 62 where they are eventually collected in a growing coil 66 on table 56. When coil 66 has attained the desired weight, cylinders 1'16 are actuated to retract piston rods 118 and thus advance retaining pins 122 to operative positions extending across the path of the descending rings 16 as indicated at 122a in FIGS. 5 and 6. Thereafter, rings begin to accumulate on the advanced pins as at 126. Moreover, as can be best seen in FIG. 6, the rings at 126 are now connected to the completed coil 66 by a single strand 128 which spirals downwardly across the path of support plate 100. Support plate 100 is then advanced to its operative position as shown in FIG. 7 by actuation of cylinder 106, thus carrying strand 128 to the right towards the general vicinity of shear 114. Once this has been acc0mplis-hed, the cylinders 116 are again actuated to retract retaining pins 122 and thus allow the rings temporarily supported thereon at 126 to drop onto plate 100 where they will remain until the completed coil 66 has been cleared from coil collecting table 56. It can therefore be seen that by temporarily withholding the rings at 126 above the path of the advancing plate 100, inadvertent engagement of a plurality of rings by the forward edge of the plate is avoided, in spite of the fact that the plate may be advancing at a relatively slow rate due to limitations imposed by its inherent inertia.
Following advancement of plate 100 to its operative position and retraction of pins 122, the connecting strand 128 must then be severed prior to clearing the completed coil 66 from the apparatus. To this end, a strand positioning device generally indicated by the reference numeral 130 is provided to positively carry strand 128 directly into the jaws of shear 114. As can be best seen in FIG. 2, strand positioning device 130 is comprised of a positioning arm 132 mounted for pivotal movement about point 134. The positioning arm is provided with a curved edge 136 corresponding to the curvature of wall member 60 which edge terminates at one end in a somewhat hook-shaped attachment 138 which is provided with a strand retaining recess as at 140.
The positioning arm 132 is positioned adjacent a slot 142 in wall member 60 which slot is substantially closed by curved edge 136 when the arm is in its inoperative position as shown in FIG. 2. In this manner, the possibility of a rod leading end becoming inadvertently lodged in slot 142 as rod is fed into the apparatus is elfectively avoided. Positioning arm 132 is pivoted about point 134 by means of a double acting cylinder 144 provided with a piston rod 146 which is pivotally connected to the arm as at 148.
The sequence of operation followed in severing strand 128 will now be described with particular reference to FIGS. 8 to 10. Following advancement of support plate 100 to its operative position as indicated diagrammatically in FIG. 7, cylinder 144 is actuated to retract piston rod 146 and thus cause arm 132 to pivot about point 134 in a counterclockwise direction. As illustrated in FIG. 8, as arm 132 begins to pivot about point 134, hook-shaped attachment 138 will pass beneath strand 128, the strand now being engaged by curved edge 136. As shown in FIG. 9, continued pivotal movement of arm 132 in a counterclockwise direction about point 134 will cause strand 1 28 to slide along curved edge 136 until it is engaged by the hooked shaped attachment 1 38. At this point, the strand is positively engaged and as shown in FIG. 9, carried into the jaws of shear 134 where it is severed in a conventional manner.
Following the shearing operation cylinder 144 is again actuated to extend piston rod 146 and thus pivot arm 1'32 in a clockwise direction about point 134 to its inoperative position as shown in FIG. 2. In so doing, the curved edge 136 of arm 132 will again close slot 142 and thus effectively eject any rod portion which might have been drawn into the slot during the shearing operation. With strand 128 sheared, the completed coil 66 is then cleared from the coil collecting table 56 in the manner previously described by lowering guide member 62 and actuating pusher arm 78. Following the coil clearing operation, support plate is withdrawn, thus depositing the rings temporarily collected thereon on the collecting table 56.
Having thus described the invention from both a structural and operational standpoint, the novel and inventive tteatures incorporated therein will now be briefly reviewed.
By providing means above the path of advancing plate 100 in the form of fast acting retractable retaining pins 122, it is now possible to utilize a heavier support plate without regard for the problems which might otherwise be present as a result of its increased inertia. As soon as the retaining pins are advanced, further descent of rod rings is immediately interrupted, thus providing an opportunity for the support plate to be advanced at a relatively slow rate while carrying a single connecting strand 128 into the operative range of strand positioning arm 1 32. The pins may then be retracted to deposit the few rings collected thereon onto the plate. In this manner, the danger of the forward edge of plate 100 contacting more than one descending ring is avoided without decreasing the efiectiveness of the apparatus.
In addition to the above, by providing means in the form of pivotal strand positioning arm 132 for positively carrying strand 128 directly into the jaws of shear 114, the dependability of the shearing operation is markedly increased. This two step operation which initially entails carrying strand 128 into the general operative range of arm 132 by advancing plate 100 and thereafter actuating the strand positioning device 130 to carry strand 128 directly into the jaws of shear 114 obviates any chance of a malfunction which would prevent subsequent clearing of the completed coil 66 from the apparatus.
It is our intention to cover all changes and modifications of the embodiment herein chosen for purposes of disclosure which do not depart from the spirit and scope of the invention.
