Definitions

  • ABSTRACT Rod delivered in a series of rings to an elevated gathering tub in a conventional manner, is formed into an annular bundle around a mandrel of a rod bundle carrier having a base platform secured at right angles to the mandrel, the carrier being elevated so that the mandrel projects into the gathering. tub as the bundle is formed and loaded onto the base platform of the carrier.
  • the loaded carrier is lowered from the gathering tub, and is then detachably suspended from a load unit of an overhead power and free conveyor which transports the loaded carrier to other stations where operations are performed on the rod bundle At each of these other stations the bundle is not separated from the carrier but the carrier is detached from the conveyor, employed aspart of the apparatus for carrying out the operation, and resuspended from the conveyor, the loaded carrier eventually arriving at at an unloading station where the processed bundle is removed from the carrier.
  • Prior systems of this general type have generally employed one or more operations requiring the handling or transporting of a rod bundle in a relatively unsupported condition, which operations expose the bundle to the likelihood of damage.
  • These operations, together with the means employed for transporting a bundle in prior systems usually a hook of a overhead conveyor on which the bundle is suspended also impose practical limitations on the size of bundle that can satisfactorily be processed.
  • the rod is delivered in a continuous series of overlapping rings to a gathering tub where a rod bundle is formed, as illustrated in US. Pat. No. 3,452,785. This rod bundle is then handled and conveyed, as mentioned above, through subsequent processing steps.
  • the objects of the present invention are to eliminate this handling of the rod bundle, to provide continuous support for the rod bundle from the time it is formed until the processing has been completed and the bundle is ready for shipment;.and, to permit the formation and processing of rod bundles considerably larger in size than those that can be formed and handled by present systems.
  • the system of the present invention includes the combination of an overhead power and free conveyor arranged in a path of travel to serve a rod bundle forming station, an unloading station and any intermediate stations at which operations on the rod bundle are to be performed, the overhead conveyor having a plurality of load carrying units.
  • Each of these load carrying units is capable of detachably suspending a rod bundle carrier having a base platform for supporting one end of a rod bundle, and mandrel structure secured to and extending outwardly from the base platform in generally perpendicular relation therewith, the mandrel structure being designed to project axially through the rings of an annular rod bundle.
  • Each of the stations in the system includes suitable apparatus for detaching a rod bundle carrier from a load carrying unit of the conveyor, utilizing the rod bundle carrier as part of a fixture for supporting the rod bundle during the performance of the operation carried on at that station, and resuspending the rod bundle carrier from a load carrying unit of the overhead conveyor.
  • the apparatus positions an empty rod bundle carrier with the mandrel thereof projecting within the gathering tub to guide the rings of rod onto the carrier and form a rod bundle supported on the base platform of the carrier.
  • This apparatus in the form to be described herein includes the combination of a shuttle carriage operable between a station on the conveyor at one side of the gathering tub at which a load carrying unit is stopped and an empty rod bundle carrier is removed therefrom, and a station on the other side of the gathering tub at which a load carrying unit is stopped and a loaded rod bundle carrier is placed thereon.
  • An elevator device located beneath the gathering tub registers with and raises the base platform of a rod bundle carrier to place the mandrel portion thereof within the gathering tub and utilize the car- 0 rier in the formation of a rod bundle.
  • This rod bundle and carrier become a unit in the system and remain together until the processing of the rod bundle has been completed.
  • the unity of the rod bundle and carrier is made possible at least in part by employing the base platform of the carrier not only as a support for the rod bundle, but as a fixture in the processing operations, the base platform being provided with handling or registry elements engageable by complementary elements of the apparatus of the system, and with suitable means such as apertures to cooperate with apparatus for applying bands to the bundle supported on the carrier.
  • the mandrel structure of the carrier is preferably capable of supporting a rod bundle with the axis thereof extending either substantially vertically or substantially horizontally, and this structure consists of a plurality of beams secured at one end to the base platform and arranged in radially spaced relation to an axis perpendicular to the base platform, the outer ends of the beams forming a tapered nose portion.
  • Apparatus at an intermediate station such as a compacting and'banding station, or an inspection and testing station, includes a table moveable into engagement with the base platform of a rod bundle carrier suspended from a stopped load carrying unit of the conveyor to detach the rod bundle carrier therefrom.
  • This table is preferably moveable transversely to the path of travel of the overhead conveyor, and is also rotatable between a position in which the base platform of the carrier is horizontal and a position in which the base platform is substantially vertical.
  • FIG. 1 is a schematic plan view of thesystem of the invention in-cluding an overhead power and free conveyor and stations at which a rod bundle is formed and processed;
  • FIG. 2 is an enlarged sectional elevation taken as indicated by the line 22 of FIG. 1 showing the apparatus of the system at a rod bundle forming station;
  • FIG. 3 is a plan view of the apparatus of FIG. 2, taken substantially as indicated by the line 3-3 thereon;
  • FIG. 4 is an elevation of apparatus provided at one of the other stations of the system for removing a rod bundle carrier from a load carrying unit of the overhead conveyor, performing an operation on the rod bundle supported by the carrier and resuspending the rod bundle carrier from the load carrying unit of the overhead conveyor.
  • FIG. 1 schematically illustrates representative portions of a rod bundle forming and handling system incorporating the features of the invention. These portions include rod bundle forming stations and 11, compacting and banding stations 12 and 13, an inspection and testing station 14 and an unloading station 16, it being understood that the number and relative location of these stations in this view is not intended to be represenative to any particular installation.
  • the stations of the system are served by an overhead power and free conveyor 18 having load supporting tracks shown in solid line 19 and power line tracks 20 for supporting a propelling chain and pushers.
  • the construction and arrangement of the load supporting and power line tracks 19 and 20 is conventional, the track 20 being formed by an I-beam and the track 19 being formed by a pair of facing channels supported below the track 19 by track hangars 21.
  • Load carrying units 22, supported on the track 20, are mainly of conventional construction and hence have not been shown in detail.
  • Each of these load carrying units consists of a front driving trolley connected to a rear trolley by a load bar 23, a comparable load carrying unit being illustrated in U.S. Pat. No. 3,498,212.
  • the driving trolley will ordinarily be equipped with a retractable driving dog as illustrated in U.S. Pat. No. 3,044,416, and the load carrying unit may be transferred from one power line to another and stopped where desired as illustrated in U.S. Pats. Nos. 3,314,377 and 3,229,645.
  • the load bar 23 is equipped with a depending hook 24 capable of detachably suspending a rod bundle carrier 26 (FIGS. 2 and 3).
  • Each rod bundle carrier 26 has a base platform 28 and a mandrel 29 secured thereto, the mandrel extending outwardly from the base platform in generally perpendicular relation therewith.
  • the structure of the mandrel 29 includes a longitudinally extending member 30 defining the axis of the mandrel and a plurality of beams 3l.arranged radially about the member 30 and secured thereto, each beam being provided along its outer edge with a wear or guide plate 32, and the beams and wear plates being tapered inwardly at the outer end 33 of the mandrel to form a tapered nose section 34.
  • a transversely extending aperture 36 is provided adjacent the outer end 33 of the mandrel and is detachably engageable with the hook 24 of a load carrying unit.
  • Each of the rod bundle forming stations 10 and 11 of FIG. 1 includes an elevated gathering tub 40 to which rod is delivered in a continuous series of overlapping rings 41 on suitable conveying structure 42.
  • a gatheringtub 40 is schematically illustrated in FIG. 2 and the mandrel 29 of the rod bundle carrier 26 is designed to and returning from the unloading station 16 are diverted to one of the rod bundle forming stations 10 or 11 served by branch portions 43 or 44 respectively of the overhead power and free conveyor.
  • Each of these branch portions 43 and 44 is arranged with a stopping station 46 adjacent to one side of the gathering tub 40 at which a load carrying unit 22 can be stopped for detaching an empty rod bundle carrier 26 therefrom, and with a second stopping station 47 adjacent to the opposite side of the gathering tub 40 at which a load carrying unit 22 can be stopped to resuspend a loaded rod bundle carrier 26 thereon. Between these stations 46 and 47, the overhead conveyor passes underneath the conveying structure 42 for the rings of rod 41.
  • a load carrying unit leaving one of the rod bundle forming stations 10 or 11 supports as a unit, a rod bundle carrier 26 loaded with a rod bundle, and conveys this unit to one of the stations 12 or 13 where a compacting and banding operation is performed thereon, to any subsequent station such as the inspection and testing station 14 where other operations are performed thereon, and eventually to the unloading station 16 where the completely processed bundle is separated from the rod bundle carrier.
  • This apparatus consists of a carriage 50 having wheels 51 supported on rails 52 and an open frame having ends 53 and sides 54 capable of supporting the base portions 28 of two rod bundle carriers 26 in positions defined by recesses 56 in the carriage frame.
  • the carriage is movable back and forth on the rails 52, in shuttle fashion, by a suitable reversing drive mechanism 58 (FIG. 3), and the rails 52 are carried by suitable frame structure 60 which can be reciprocated in a vertical direction by bell cranks 61 mounted on a suitable base 62 and movable by fluid pressure cylinders 64.
  • An elevator device 66 is located beneath the gathering tub 40 and includes a table 67 moveable in vertical directions by an actuating cylinder 68, the table being located within the sides and ends of the open frame of the carriage 50, and being provided with upwardly projecting handling elements or pins 70 which are registerable in complementary elements or holes 72 in the base platform 28 ofa rod bundle carrier 26.
  • This stablizer device 74 is suspended by a link 75 and by a rod 76 slidably engaging a pivoted bearing 77 and is moveable from a retracted position shown at the right hand side of FIG. 2 to an operative position shown at the left hand side thereof in which an upper projecting portion 78 of the device is engageable by the hook 24 and a lower projecting portion 79 is engageable by the mandrel 29 of the rod bundle carrier 26.
  • the frame 60 With the carriage 50 in the position shown in FIG. 2, the frame 60 is raised by operation of the bell cranks 61 and actuating cylinder 64 a distance sufficient to engage the base platform 28 of the rod bundle carrier 26 and raise the carrier relative to the hook 24 suspending it.
  • the carriage 50 is then moved by the drive mechanism 58 to place the rod bundle carrier 26 under the gathering tub 40 and over the elevator table 67 which is moved upwardly, the elements 70 on the table 67 registering in the holes 72 of the carrier base platform, raising the carrier to a position in which the mandrel 29 thereof projects well within the gathering tub 40.
  • Moveable baffles or gates are conventionally provided in the gathering tub to separate one bundle from the next, and these gates would be retracted as the mandrel 29 is projected into the gathering tub, permitting the mandrel to collect any rings of rod that may have accumulated therein and guide these rings into the beginning of a bundle supported on the base platform 28 of the carrier 26. Rings of rod 41 delivered to the gathering tub while the carrier is positioned therein are guided into bundle formation by the mandrel 26 thereof until a bundle 82 of the desired size is formed on the bundle carrier 26.
  • FIG. 4 Such a station is schematically illustrated in FIG. 4.
  • One of the stabilizer devices 74 and a load carrying unit stop 80(FIG. 1) aid in positioning a load carrying unit 22 and bundle carrier 26 relative to the apparatus 84 shown, which is capable of removing the rod bundle carrier 26 and bundle 82 as a unit from the hook 24, tilting the rod bundle carrier from a position in which the base platform 28 thereof is horizontal to a position in which the base platform is vertical and the axis defined by the mandrel extends horizontally, returning the rod bundle carrier to. the original position and resuspending it from the hook 24.
  • the rod bundle carrier 26 may also be moved transversely out of the path of load carrying units on the conveyor.
  • the apparatus 84 includes a horizontally reciprocatable base 86 provided with a pair of vertically extending rods 87 of pressure cylinders 88, one of which is shown, slidably supported by vertically spaced bearings 89 and 90 of base structure 91.
  • a carriage 92 has collars 93 fixed on the rods 87 and a table 94 connected to the carriage 92 by a pivot 95 is moveable by a fluid pressure cylinder unit 96 pivoted at 97 to the carriage 92 and connected to a crank 98 secured to the table 94.
  • the table 94 is equipped with pins 100 registerable with the holes 72 in the base platform 28 of the rod bundle carrier 26, and with a fluid pressure actuated clamp 102 for securing the base platform 28 to the table.
  • the apparatus may also be provided with fixed abutments 104 and 106 engageable by the base platform 28 when pivoted to the vertical position shown in fullline.
