r INVENTOR. MARTIN ,GILVAR ATTORNEYS PRODUCT HANDLING SYSTEM FOR COOLING BEDS BACKGROUND OF THE INVENTION Bar mills finishing straight lengths generally have an assembly table interposed between the cooling portion of the cooling bed and the table feeding the bar shear.
The assembly table allows batching of the product for subsequent multiple shearing by providing a reservoir between the carryover racks and the runoff rolls. Bars are continuously deposited in the reservoir as they arrive one by one from the cooling bed. The collected bars are removed from the reservoir in batches to be placed on the runoff rolls.
The assembly table of the prior art is typically a shuffle bar table or a flat top chain transfer. Both of these types of assembly tables allow the collected bars to stack against one another in intimate contact. This type of assembly has two inherent disadvantages; first, cooling is impeded because the bars instead of being separated as they were on the carryover racks are now in contact; secondly, the batch of bars placed together on the runoff rolls must be reseparated at the bar shear into an exact predetermined pattern when the cutting of the bars is to be done by notched knives.
SUMMARY OF THE INVENTION This invention discloses a system which allows effective assembly of a batch of bars in reservoir fashion while maintaining the individual hot bars in spaced parallel relation prior to their being placed on the runoff rolls. Since the bars are maintained in spaced relation in the reservoir, cooling is facilitated and this, in turn, may permit the use of a narrower carryover portion. Since the spacing of the bars in the reservoir portion is the same as the spacing of the bars when they are thereafter placed on the notched or grooved runoff rolls, it is then unnecessary to reseparate the bars when they arrive at the notched shear because the spacing of the bars on the rolls is the same as the spacing of the notches in the shear.
In carrying out the invention, a preferred form comprises three sets of chains which are used to move the bars from the carryover rack to the runoff rolls. The bars on leaving the carryover racks are assembled in spaced parallel relation between aligned dogs on a first set of chains, hereinafter called the assembly chains. These chains advance step by step to receive the succession of bars from the carryover racks. The bars deposited on the assembly chains are counted and when the batch equals the number of bars that are to be positioned in one group on the runoff rolls, the assembly chains are quickly advanced a few spaces during the dwell before the delivery of the next bar from the carryover rack to carry the batch of bars to a position over a second set of chains, hereinafter called the first lifting chains. These first lifting chains are interspersed between the assembly chains and extend well beyond the assembly chains toward the runoff rolls. With the bars on the assembly chains and over the first lifting chains, the latter are then raised, picking up all of the first batch of bars from the assembly chains but continuing the bars in the same spaced parallel relationship. The batch of bars is then quickly advanced by the first lifting chains to a reservoir area beyond the ends of the assembly chains. The first lifting chains are then lowered to a position which is below the level of a third set of chains, hereinafter called the second lifting chains so that the spaced parallel bars are now supported by the second lifting chains in part of the reservoir area which is between the assembly chains and the runoff rolls. The second lifting chains are interspersed between the first lifting chains and between the runoff rolls. If the runoff rolls are clear, then the second lifting chains which extend beyond the runoff rolls are raised above the level of the runoff rolls and advanced to bring the spaced parallel bars over the runoff rolls. The spacing of the grooves on the run-off rolls will match the spacing of the bars on the lifting chains so that when the second lifting chains are lowered, the bars will be deposited in the same spaced relation in the grooves of the runoff rolls.
With the bars now positioned on the runoff rolls, the rolls are advanced to drive the leading ends of the bars against a transversely extending stop. This aligns the leading ends of the bars. The stop is then withdrawn and the bars are advanced a short further distance until they are brought to a position over the notched shear blade. The forward movement of the bars is stopped and the shear actuated to cut the bars at the selected position. The bars may then be advanced on the runoff rolls a predetermined distance and the shear operated again to provide the required length of bars.
While the runoff rolls are being actuated to deliver the bars to the shear, a second batch of bars is being collected, first on the assembly chains, then carried by the first set of lifting chains to the reservoir area where they are delivered to the second set of lifting chains pending removal of the first batch of bars from the runoff rolls. As soon as the runoff rolls are cleared, the second batch of bars is delivered to the grooved runoff rolls for subsequent shearing in the same manner as the first batch.
If the runoff rolls are not clear or if there has been a delay at the shear so that the bars in the reservoir area on the second lifting chains cannot, for the time being, be delivered to the runoff rolls, then a next batch of bars may be carried from. the assembly chains by the first lifting chains to occupy the rear part of the reservoir area on the second lifting chains behind the-first batch of bars. While the second lifting chains cannot be unduly long because of space limitation in the mill, it is preferable that they be long enough to receive at least two successive batches at the reservoir position to cope with any delays downstream.
While the bars are deposited in the grooves on the runoff rolls by the second lifting chains according to their original spacing on the assembly chains and should thereafter travel in parallelism to the shears, it has been found that there is some tendency for the bars which are rarely perfectly straight to deviate from their intended course in the grooves of the rolls. Such deviation must be avoided if the bars are to enter the shear in alignment with the notched shear blades. Accordingly, horizontal apron plates positioned between the rolls have been included to support and direct the bars. These plates may be plain or may have parallel guideways that match the spacing of the bars on the rolls to assist in guiding the bars as they move from one runoff roll to the next.
A second form of the invention comprises only two sets of chains, the assembly chains and the lifting chains. In this arrangement, the single set of lifting chains acts in the dual capacity of lifting the batch of bars from the assembly chains, moving the bars forward to a reservoir position and finally carrying the bars to the runoff rolls. This result is accomplished by providing means for raising alternatively the near sprockets of the lifting chains, the far sprockets of the lifting chains, or both sprockets simultaneously whereby l bars may be picked up from the assembly chains and carried to the reservoir area without interfering with bars which may then be on the runoff rolls, (2) bars may be moved from the reservoir position to the runoff rolls without picking up bars then on the assembly chains, or (3) bars may be picked up from the assembly chains and moved to the reservoir area while at the same time bars at the reservoir area may be moved to the runoff rolls.
As will be illustrated and explained in the subsequent detailed description of the invention, the mechanism lends itself to the delivery in parallel spaced condition of various diameter bars from the carryover racks to the grooved runoff rolls without necessitating any changes in the spacing of the dogs on the chains or changing the spacing of the grooves in the runoff rolls.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIGS. 1 and 2, carryover racks 2 are adapted to deliver in conventional fashion a succession of bars 4. These bars will ordinarily be round but the invention is not limited to the delivery of round bars. The bars 4 are delivered to a plurality of parallel assembly chains 6 which, as shown in FIG. 2, are in substantial alignment with the runoff rolls 8. The assembly chains 6 are carried by spaced pulleys or sprockets I0 and I2 mounted on shafts 14 and 16. Sprocket 12 is the driving sprocket with the shaft 16 rotated by conventional drive mechanism to advance the chains 6 step by step to receive the bars 4 as they come from the carryover rack 2. Sprocket is an idler.
Each chain 6 has its upper course supported by a horizontal bar 18 (see FIGS. 1 and 4) so that there will be no intermediate sag of the chain between the sprockets 10 and 12. The chain 6 illustrated in FIG. 3,
comprises a succession of alternating side links 20 and 22 between which are centrally located aligned rollers 24 which rest on horizontal bar 18 to facilitate chain movement thereon. Each of the links 20 and 22 has a laterally extending integral dog 26 and 28, respectively. The spacing between the dogs and rate of advance of chains 6 is such that the bars 4 arriving from the carryover racks 2 are positioned in uniform spaced arrangement on the advancing chains 6.
FIG. 4 also shows spaced guides 27 and 29 which serve to prevent the chain 6 from tipping to one side or the other. The guides 27 and 29 are affixed to chain supporting bar 18.
As can be seen in FIG. 3, small bars 4a may be deposited between each pair of dogs, intermediate size bars 4b may be deposited between every other pair of dogs, and larger size bars such as 40 may be deposited between every third pair of dogs of the chain. The object of this increased spacing as the bars get larger are (l) to be sure that the bars do not touch each other so that cooling will be unimpeded, and (2) to distribute heavy bars across the width of the shear knives so as not to overload the shear. When small bars 4a are being deposited on the assembly chains, the chain driving mechanism will be set to advance the chains step by step a distance of one dog. When intermediate size bars 4b are being deposited on the assembly chains, the chains will be advanced step by step a distance of two dogs and when larger bars 4c are being deposited on the chains, the step by step advance of the chains will be a distance of three dogs.
Referring to FIG. 1, it will be noted that the runoff rolls 8 are grooved and the spacing of these grooves is the same as the spacing of the dogs 26 and 28 shown in detail in FIG. 3.
Let it be assumed that small bars 40 are being delivered by the cooling bed 2 to chains 6 so that one bar is being deposited between each pair of adjacent dogs 26 and 28. Let it be further assumed that it is desired to shear 10 bars 4a simultaneously as they may be delivered by the runoff rolls 8 to the shear. In such case, as soon as 10 bars 4a have been deposited side by side on chains 6, a counting device 30 of known construction will impart the information to the driving mechanism of shaft 16. This will result in an immediate advance of chains 6 for a distance of five or six dogs thereby to space the last bar of the batch of bars 4a from the first bar of the next batch about to be delivered from the carryover racks 2. The advance of chains 6 occurs during the dwell period between successive deliveries of bars 4a, from the carryover racks 2 so that there is no interruption in the operation of the carryover racks. The first batch of 10 bars on the assembly chains 6 will now be located in the vicinity of the section indicated at A in FIG. I and will be located over the left hand part of the set of first lifting chains 32 which are carried by idler sprockets 34 and driving sprockets 36 mounted respectively on shafts 38 and 40. The lifting chains 32 are constructed in the same manner as chains 6 and as illustrated in detail in FIG. 3. Theupper course of each chain 32 is supported by a longitudinally extending horizontal bar 42 with associated chain guides 41 and 43 (similar to guides 27 and 29 shown in FIG. 4). Bar 42 prevents sag of chain 32 and also maintains chain 32 in a normal position below the upper course of chain 6. The right hand end of bar 42 is supported by the upper arm 44 of a bell crank 46 which is pivoted at 48. The bell crank 46 may be caused to rotate through operation of a piston 50 and cylinder 52 utilizing air or fluid pressure.
The left hand end of bar 42 is supported by an inclined bearing surface 54, a roller 56 and a corresponding inclined upper bearing surface 58 which is integral with bar 42. Upon rotation of bell crank 46 clockwise, bar 42, while remaining horizontal, is moved diagonally upward to the right and in so moving raises chain 32 vertically above the level of chain 6. In this way, chains 32 pick up the batch of bars located in area A holding them in the same spaced parallel relation. As soon as the 10 bars 4a now carried by chains 32 are clear of chains 6, the drive sprocket 36 is advanced to bring the bars to a reservoir position generally designated at B at which position they will overlie the left hand part of a second set of lifting chains 60. Chains 60 are carried by idler sprockets 62 and drive sprockets 64 mounted respectively on shafts 66 and 68. A horizontal supporting bar 70 extends under the upper course of each chain 60 to prevent sagging of the chain. Chain guides 69 and 71 (similar to guides 27 and 29 shown in FIG. 4) are affixed to bar 70 (see FIG. 2). The normal position of the upper course of chain 60 is above chain 32 and lower than the uppermost surface of the runoff rolls 8. As soon as the batch of bars has arrived on chains 32 at position B, the bell crank 46 is rotated counterclockwise lowering supporting bars 42 and chains 32 to the normal inoperative positions below the level of chains 60 whereby all of the special parallel bars 4a are now deposited between the dogs 26 and 28 of chains 60 in exactly the same spaced relation they were in when originally deposited on the dogs of chains 6.
Each bar 70 is supported at its right hand end by a bell crank 72 similar to bell crank 46 and the left hand end is supported by inclined surfaces and intermediate rollers (not shown) similar to parts 54, 56 and 58 at the locations 74. Thus, when bell crank 72 is rotated clockwise by the piston and cylinder 76, bar 70 will lift chain 60 up to a height above the top of the runoff rolls 8. As soon as this elevation is reached and assuming that there are no bars on the runoff rolls 8, the shaft 68 and related drive sprocket 64 are rotated clockwise to advance chains 60 until the batch of bars are now in the position C over the grooved runoff rolls 8. Advance of sprocket 64 is stopped at this point and bell crank 72 is rotated counterclockwise to lower the batch of bars onto the runoff rolls 8. Since the spacing of the grooves in runoff rolls 8 is the same as the spacing of the dogs in chains 6, 32 and 60, all of the bars 4a will be deposited on the runoff rolls in the same parallel spaced arrangement that has been maintained during their transfer from positions A to B to C.
With the bars now positioned on the runoff rolls, the conventional driving mechanism of the rolls which comprises a shaft 78, beveled gears 80 and 82 are then' operated to advance all of the bars a short distance into engagement with a stop 84 as shown in FIG. 5. This causes automatic alignment of the leading ends of the bars 40. The stop is then removed and the bars are advanced a short distance further to bring their ends over the lower shear blade 86 which is notched to agree with the spacing of the bars 4a on the runoff rolls. The advance of the bars is then stopped and the upper shear blade 88 operated to cut the bars at the selected position.
After initial shearing of the bars, the rolls 8 may be advanced a predetermined distance to bring the leading ends of the bars against another stop set a predetermined distance down stream from the shear blades 86, 88. Then the shears may be again actuated to cut off a predetermined length of bars. This procedure is continued until the runoff rolls are clear of all bars.
As soon as the runoff rolls 8 are clear of the bars, the next batch of bars which have been assembled in the manner previously described and which are resting temporarily at the reservoir position B are then picked up by the second set of lifting chains 60 and advanced to their position on runoff rolls 8. This second batch of bars is then sheared in the same manner as the first batch. This succession of operation continues so long as bars are being delivered by the carryover racks 2.
When the chains 6, 32 and 60 are referred to as being carried by sprockets, it will be understood that this includes all equivalents such as pulleys or drums or other devices capable of supporting and driving the continuous chains. The chains being supported on their upper courses by bars 18, 42 and are sufficiently slack on their lower courses so that the upper courses may be raised without changing the longitudinal position of the dogs. Some small angular rotation of the idler sprockets 10, 34 and 62 occurs when the chains are raised. Thus, with the dogs of the assembly chains in alignment with the dogs of the first lifting chains and the dogs of the first lifting chains in alignment with the dogs of the second lifting chains, the spaced bars will maintain their relative positions throughout the several transfer operations from the carryover racks to the grooved runoff rolls. The alignment of the dogs on all of the overlapping chains is maintained by interrelated driving mechanism for the shafts 16, 40, 68 and 78. The details are not shown as they are conventional and well known by persons familiar with the rolling mill art.
In order to support and direct the rods as they travel from one runoff roll to the next runoff roll and finally to the notched blades of the shear, aprons 90 may be provided as indicated in FIG. 2. These aprons occupy most of the space between each chain 60 and the next runoff roll 8. The apron unit as viewed in vertical section in FIG. 8 may be triangular in shape whereby three guide systems may be readily available to accommodate small bars 4a, medium sized bars 4b, or large bars 4c, as may be delivered to the assembly chains from the carryover racks.
The aprons 90 may be rotated on a shaft 92 through 120 steps to present selectively in upper horizontal position the supporting surface 94 with guides 96 for small size bars 4a; or the surface 98 with guides 100 for medium sized bars 4b; or the surface 102 with guides 104 for large sized bars 40. If preferred, guides 96, 100
or 104 may be omitted with reliance being placed sole- I 1y on the supporting surface to carry the bars from the grooves of one runoff roll to the corresponding aligned grooves in the next runoff roll.
A modified form of the invention is shown in FIG. 7 in which there is only one lifting chains as distinguished from the two lifting chains shown in FIGS. 1 and 2.
In FIG. 7, the carryover racks 110 deliver the bars 4a, for example, to the assembly chains 112 which move forward step by step in the same manner as assembly chains 6 in FIGS. 1 and 2. Assembly chains 112 are carried by idler sprockets 114 and driving sprockets 116. The sprockets l 14 and 116 are mounted on shafts 118 and 120.
The lifting chain 122 runs from idler sprocket 124 to driving sprocket 126. The shafts 128 and 130 of these sprockets are mounted on bell cranks 132 and 134 pivoted at 136 and 138. Means is provided for lifting simultaneously the bell cranks 132 that support shaft 128 and other means for simultaneously lifting the bell cranks 134 that support shaft 130.
It will be noted that the upper course of each lifting chain 122 in its lowermost horizontal position is a substantial distance below the upper course of assembly chain 112 and below the top of runoff roll 140. The normal lowermost position of shafts 128 and 130 is such that sprockets 124 can be raised sufficiently for lifting chains 122 to pick up a collected batch of bars on assembly chain 112 without having the uppermost portion of the dogs on chains 122 being above the top of runoff roll 140. In other words, even though there may be a batch of bars on runoff rolls 140, it is possible for the lifting chains 122 to be raised at their left hand ends to pick up the batch of bars from the assembly chains 112 to move the bars to a reservoir area D without interferring with bars that may then be located in the grooves on runoff rolls 140.
Conversely, if a batch of bars is resting at the reservoir area D on the lifting chains 122, it is possible by raising sprockets 126 to transfer the bars from reservoir area D to a position over runoff rolls 140 without disturbing the batch of bars which are then currently being assembled on the assembly chains 112. The angles of inclination which the upper course of chains 122 may assume under these two conditions of operation are indicated by the dot and dash lines 142 and 144.
From the foregoing explanation with respect to the construction of FIG. 7, it can be seen that through the use of lifting chains 122 supported by vertically movable sprockets 124 and 126, it is possible to pick up a batch of bars from the assembly chains 112 and move them to a reservoir area D without interfering with any bars that may be then in position on the runoff rolls 140. Conversely, by moving the sprockets 126 vertically, bars may be moved from reservoir area D to a position over the runoff rolls without interferring with any bars then being assembled into a batch on the assembly chains 112. Finally, it is possible by raising both sprockets 124 and 126 vertically to pick up a batch of bars from the assembly chains 112 and move the bars to reservoir area D while simultaneously moving a batch of bars that have been resting on chains 122 at reservoir area D to a position over'the runoff rolls 140.
It will be understood, of course, that the dogs on assembly chains 112 and the dogs on lifting chains 122 will always be in longitudinal alignment when the chains are stationary so that when the bars are transferred from the assembly chains to the lifting chains, or from the lifting chains to the grooves of the runoff rolls 140, they will always remain in the same spaced parallel relationship which prevailed as the bars were delivered from the carryover racks to the assembly chains 112.
The upper course of chains 122 will be prevented from sagging by means of a supporting bar 146 carried at its ends by the shafts 128 and 130 or the bell cranks. The chain and supporting bar arrangement in FIG. 7 is similar to that illustrated in FIG. 4.
The bell cranks 132 and 134 shown in FIG. 7 used to support and raise shafts 128 and 130 could also be used as the means for supporting and raising sprockets 34 and 38 and related chains 32 and sprockets 62 and 64 and related chains 60 shown in FIGS. 1 and 2.
Modifications and further applications of the invention will now be apparent to those skilled in the art without departing from the spirit and scope of the invention.
