Definitions

  • the present invention constitutes an improvement on the mechanisms disclosed in the aforesaid two mentioned patents.
  • the invention is an improvement in that the cropped pipe is delivered directly from the shear to a crop box located below without passing through a delivery pipe.
  • a major feature of the present invention involves the use of two side by side relatively closely adjacent rotary shears to which the rod is selectively directed by a switch pipe.
  • the two rotary shears preferably are mounted on a common support and are driven by a single power source.
  • the two rotary shears could be mounted side by side on separate supports with each shear being driven by an individual power source.
  • Each shear consists of two knives or blades, which, coming together in their circular operative paths with the rod therebetween, sever the rod in known manner.
  • the two side by side rotary shears differ in this respect.
  • the blades of one shear (hereinafter sometimes referred to as the up" shear) are so arranged that when the rod is severed, the leading end of the next section will automatically be directed in an upwardly sloping direction to pass above a separator and thence into the open upper other shear (hereinafter sometimes referred to as the down shear) function in an opposite manner, namely, that the leading end of the next section will be directed to a position below the separator to engage a deflector which will put the cropped part of the rod on a downward sloping path toward the crop box.
  • the shear having the blades arranged to cause upward movement of the new leading end will be used, whereas, if the following section is to go to the crop box, the other shear, having blades arranged to direct the new leading end downwardly will be used.
  • Another feature of the present invention resides in the temporary removability of the separator and the capacity to shift the deflector from up to down position whereby the rotary switch can be operated to place the rod then passing through the rotary switch in the lower position and to present the empty entrance of the switch in the upper position where it will be ready to receive the leading end of the next section when the rod is thereafter divided.
  • the invention will be described in more detail hereinafter.
  • FIG. 1 is a plan view running from the last roll stand of the mill to the location of the side by side shears and showing also the switching mechanism for directing the rod to the upshear or the down shear.
  • FIGS. 2A and 2B are side elevations of the invention which collectively run from the last roll stand of the mill through the side by side rotary shears, the housing containing the separator and the deflector, and the rotary switch to the several pipes to which the rod can be directed for collection at a selected pouring reel or laying head. This view also shows the crop box to which cropped pieces go directly without passing through any pipe.
  • FIG. 3 is an enlarged vertical section showing in more detail the blades of the down shear, the separator and the deflector. In this blade arrangement, the new end of the rod when out will be directed below the separator.
  • FIG. 4 is a section similar to FIG. 3 showing the blades of the up shear reversed from those of the down" shear to cause the new leading end to pass above the separator.
  • FIG. 5 is a vertical section taken on the line 5-5 of FIG. 2B illustrating the mechanism whereby the separator may be temporarily removed from its normal position.
  • FIG. 6 is a schematic view of a leading end engaging the deflector enroute to the crop box.
  • FIG. 7 is similar to FIG. 6 showing the leading end going to the crop box after having been cut from the following part of the rod by the up" shear.
  • FIG, 8 shows the new leading end directed to a position passing above the separator and into the upper entrance of the rotary switch.
  • FIG. 9 is similar to FIG. 8 but with the separator removed and the deflector dropped and the rotary switch rotated through to place the rod in lower position.
  • FIG. 10 shows the separator repositioned above the rod and the deflector still in down position.
  • FIG. I I shows the rod divided by the up shear with the new leading end of the next section directed to a DESCRIPTION OF THE PREFERRED EMBODIMENT
  • the last stand of the rolling mill is shown at 2.
  • the rolled rod 4 passes from the last stand in conventional manner through a pipe 5 to a switch generally referred to at 6, which comprises a first pipe 8 pivoted at 10 and a second pipe 12 aligned with pipe 8.
  • the common support 14 for the adjacent ends of pipes 8 and 12 is arranged for limited transverse movement.
  • the right hand end of pipe 12 is mounted on a support 16 capable of moving the discharge end of pipe 12 from a first position 18 to a second position 20.
  • Pinch rolls 21 aligned with switch position act to grip and advance the tail end crop to deliver it properly to the crop box.
  • a rotary shear mechanism Closely adjacent to the discharge end of a delivery pipe 22 is a rotary shear mechanism generally referred to at 23.
  • This mechanism comprises two side by side rotary shears mounted on common operating means.
  • One of the rotary shears is aligned with the switch pipe first position 18 and the other rotary shear is aligned with the switch pipe second position 20.
  • the shear blades or knives that are aligned with the first pipe position 18 are shown in FIG. 4 and numbered 24 and 26, and the blades aligned with the second pipe position 20 are shown in FIG. 3 and numbered 28 and 30.
  • blades 24 and 26 shown in FIG. 4 are arranged the reverse of blades 28 and 30 shown in FIG. 3.
  • the separator 32 shown on a reduced scale in side elevation in FIG. 2, on an enlarged section in FIG. 3 and in enlarged end elevation in FIG. 5 is a strong horizontal plate located within a housing 36 through which the rod 4 passes.
  • the left side of the separator 32 as viewed in FIG. 5 passes through a horizontal opening 38 in the side of housing 36 and is attachedto a vertical web 40 having upwardly extending arms 42 pivoted at 43 on an upward extension of housing 36.
  • the arms are connected to a lever 44 which may be moved by actuation of air cylinder 46.
  • the separator 32 in this way may be quickly removed from the housing 36 by downward movement of the piston of air cylinder 46 causing the separator 32 to swing outwardly through opening 38 to the position 32 shown in FIG. 5.
  • the reason for the temporary removal of the separator 32 is to permit rotation of the rotary switch 34 to shift rod 4 from its upper position above the separator as shown in FIG. 8 to a lower position 4' below the separator as shown in FIGS. 9 and 10.
  • the deflector 48 is best shown in detail in FIGS. 28 3 and 4. In its down position shown in FIG. 3, the deflector covers the entrance to the crop box chute 56 and is adjacent the bottom 50 of the housing 36. In its up position as indicated at 48' in FIG. 4, its forward end engages the underside of separator 32 immediately behind a shoulder 51. The entrance to chute 56 is then open. When the deflector is in down position, there is sufficient space between it and the underside of separator 32 to permit the rod 4 to pass therebetween. When the deflector is in up position as at 48' in FIG. 4, the leading end of any rod directed thereto will be deflected downwardly to travel freely through chute 56 to a crop box 57 therebelow.
  • the deflector 48 is actuated by an air cylinder 52 whose piston 53 is pivotally connected to a lever arm 54 (see FIGS. 23 and 5).
  • the chute 56 may include a longitudinally extending gate 58 swingable from one side of the chute to the other about a centrally located pivot 60 to direct the cropped portions specifically to a scrap bin or a sampling bin which bins together comprise the crop box 57.
  • the gate 58 is moved from one position to the other by an air cylinder 62 connected to the pivot 60 by an arm 64.
  • the rotary switch 34 shown in FIG. 2B is substantially the same as the rotary switch illustrated in the previously referred to U.S. Pat. No. 3,109,340.
  • This switch which is rotatable back and forth through I80" has two passages 66 and 68 therethrough.
  • the passage 66 leads to pipe 70 and the passage 68 leads to pipe 72.
  • the delivery ends of pipes 70 and 72 are separately movable up and down by two independent air cylinders, one of which is indicated at 74.
  • Each air cylinder is arranged to put the discharge end of each pipe in alignment with a pipe running to any empty pouring reel (or laying reel) so that the oncoming rod may be directed thereto.
  • One set of pipes 76, 78 and 80 cooperates with pipe 70 and a second set of three pipes (therebehind and not shown) cooperates with pipe 72.
  • the leading end of the rod 4 delivered by the last stand 2 of the mill is directed through pipe 5 and into the first pipe 8 of switch 6, whence it passes on to the second pipe 12.
  • the delivery end of the pipe 12 is shown in full lines at the first position 18in FIGS. 1 and 2A.
  • the deflector 48 will be in up position 48' as shown in FIG. 6 and the blades 24 and 26 will be open so the rod 4 passes therebetween along its pass-line to enter housing 36 on the underside of separator 32.
  • the leading end of the rod will then engage the underside of deflector 48 and be deflected downwardly into chute 56.
  • the leading end of the rod 4 will have been detected by a sensing device 86 (see FIG. 1) which puts the shear mechanism 23 in operation after a predetermined length of the leading end of the rod has passed the sensor enroute to the crop box.
  • a sensing device 86 see FIG. 1 which puts the shear mechanism 23 in operation after a predetermined length of the leading end of the rod has passed the sensor enroute to the crop box.
  • the rod 4 traveling through pipe 12 along the line of first position 18 will as noted by aligned with up shear blades 24 and 26.
  • the front severed portion 88 (see FIG. 7) will be deflected down into the crop box, but the leading end 90 of the following portion of rod 4 will be directed by operation of shear blades 24 and 26 upwardly at a small angle so that it will be delivered to the top side of separator 32.
  • the rod 4 continues over separator 32 through the housing 36 to pass into the empty upper entrance 66 of the rotary switch 34, thence on through pipe 70 (see FIG. 8) and into one of the pipes 76, 78 or 80 leading to a vacant pouring reel.
  • Air cylinder 46 is actuated to swing the separator 32 out of housing 36 as shown at 32 in FIG. 5.
  • the deflector 48 is dropped from up position 48 to down position 48 by operation of air cylinder S2.
  • the rotary switch 34 is then actuated to rotate through 180 to place the passage 68 in the upper position and passage 66 in the lower position as shown in FIG. 9 with the rod 4 still passing through pipe 70 enroute to the pouring reel.
  • separator 32 is returned to its normal position within housing 36, as in FIG. 10, and the deflector 48 remains in down position.
  • the rod 4 is now in condition to be divided by the blades 24 and 26 of the up shear which are automatically put into operation as in FIG. 11 when the predetermined weight or length of rod has been deposited in the first pouring reel.
  • the leading end 91 (see FIG. 11) of the severed rod 4' automatically is directed to the top side of separator 32, thence on into the upper empty entrance 68 in the rotary switch 34, through pipe 72 and thence to the appropriate pipe leading to the empty pouring reel in which the next coil is to be assembled.
  • the tail end of rod 4 that was running through entrance 66 and pipe 70 of the rotary switch has now passed on to the pouring reel and the entrance 66 is again open.
  • rod 4' of FIG. 11 Assuming that the rod 4' of FIG. 11 will be of a proper length to complete the second coil of rod in the appropriate pouring reel, then rod 4' must be cropped at its tail end in accordance with customary practice. This is accomplished in the following manner.
  • the switch pipe 12 is shifted from first position 18 to second position in which it will become aligned with the down? shear blades 28 and shown in FIGS. 3 and 12. With switch pipe 12 in position 20, the rod 4' continues to pass over separator 32 into rotary switch entrance 68 and thence through pipe 72 to the associated pouring reel. While this is going on. the deflector 48 is swung to up position 48 prior to the next actuation of the down shear.
  • the down" shear is then actuated by a sensor causing rod 4' to be sheared an appropriate distance ahead of the tail end to make a suitable tail end crop.
  • the shearing is done by the blades 28 and 30 shown in FIGS. 3 and 12. These blades are arranged the reverse from blades 24 and 26 so that when shearing occurs the leading end 92 of the tail end crop portion 94 is directed downwardly as shown in dotted line in FIG. 12 to pass below separator 32 to engage the deflector 48 and be sent downwardly through chute 56 to the crop box 57.
  • the sensor that puts the down shear into operation also causes the pinch rolls 21 to close on the rod so that the cropped tail end will continue to be advanced at the same speed on its way to the crop box.
