Definitions

  • an optical gate device which generates a light beam extending coaxially with the coil supporting drum of the coil holder.
  • a timing relay is actuated at the moment when the light beam may pass unobstructed through the central coil opening.
  • the timing relay stops the upward motion of the hoisting trough after the latter moves additionally through a distance that is identical to the radius of the coil opening. In this manner the coil is automatically brought into axial alignment with the coil holder drum.
  • This invention relates to an apparatus associatedwith the loading for the purpose of unwinding a sheet metal coil on a coil holder by means of a hoisting trough which lifts the coil to a height where the central coil opening is in alignment with the drum or similar coil supporting compoment of the coil holder.
  • an optical gate device that generates a light beam which is coaxial with the holder drum axis and which is directed to a mirror disposed normal to, and intersected by the holder drum axis.
  • the optical gate device is associated with a timing relay by means of which the lifting of the coil is controlled when the light beam passes through the central coil opening.
  • FIG. 1 is a schematic side elevational view, partially in section, of a first embodiment of the invention in which the coil is out of alignment with the holder drum;
  • FIG. 2 is a view similar to FIG. 1, showing the coil in alignment with the holder drum;
  • FIG. 3 is a schematic side elevational view of a second embodiment of the invention.
  • FIG. 4 is a schematic side elevational view of a third embodiment of the invention.
  • FIG. 5 is a schematic front elevational view illustrating a storage ramp and a hoisting trough and FIGS. 6a, 6b and 6c schematically illustrate a circuit diagram of the invention showing three successive positions of the coil with the associated switching state of the circuit.
  • the coil holder shown therein comprises two oppositely arranged stands 2 and 3 which include supports for respective shafts 7 and 9. Each shaft carries, in a face-to-face orientation, axially aligned respective cones 6 and 8 from which the sheet metal coil 1 is suspended.
  • the coil is shown positioned on a hoisting trough 4 which is vertically movable by means of an elevating and lowering mechanism 5. Further, FIG. 1 shows the coil 1 in a position in which the central coil opening is out of alignment with the holder cones 6 and 8.
  • the holder stand 3 carries adjacent one end of the hollow shaft 9, an optical gate device 10 which emits a light beam that passes coaxially through the hollow shaft 9 and the hollow cone 8 in the direction of the oppositely located cone 6.
  • the latter carries a mirror 13 arranged centrally and perpendicularly with respect to its axis of rotation.
  • the light beam 11 is interrupted by the lateral, radial edges of the windings of the coil 1, while in the centered or aligned position of the coil 1 in FIG. 2, the emitted light beam 12 is uninterrupted and is thus adapted to impinge on the mirror 13.
  • the coils 26, 2 7, 28 are held blocked on a sloping storage ramp 31 and are allowed, in sequence, to roll by gravity onto the hoisting trough 4.
  • the coil positioned on the latter actuates, by virtue of its weight, a switch 30, 30a, whereby the energizing circuit 32 of a drive motor 33 associated with the lifting mechanism 5 is closed.
  • the drive motor 33 which is provided with a braking mechanism, starts and drives through a mechanical connection M and by means of a stepdown gear (not shown), a vertical spindl'e of the hoisting mechanism 5 to thus perform the hoisting step. In this manner the coil 1 is lifted.
  • the light beam 1 l emitted by a light source 10a of the optical gate device 10 does not impinge on the photo-diode 10b.
  • the latter is in a circuit with a switch 10c which forms part of the optical gate device 10 and which is in its open position.
  • the switch 10 controls an energizing circuit of a timing relay 34.
  • the lowest position of the hoisting trough 4 for receiving the individual coils is chosen in such a manner that for any coil, independently from its outer diameter, the upper edge of the central coil opening is at least 40 50 millimeters below the light beam extending coaxially with the shaft 9. In this manner the light beam is interrupted by the radial edge faces of the windings in the coil 1.
  • FIG. 6b at the moment the light beam 12 is allowed to pass through the central opening of the coil 1, it will be received by the photodiode 10b and, as a result, the switch will close. This occurrence starts a timing mechanism 34a which is connected to a presently closed switch 34b in the motor circuit 32.
  • the timing mechanism 34a and the switch 34b form part of the timing relay 34.
  • the continuously rising coil 1 is at a distance from its desired terminal position that is identical to the radius of the central coil opening.
  • the timing mechanism 34a is adjusted in such a manner that after a delay during which the coil is additionally lifted a distance that corresponds to the radius of the central coil opening, the timing mechanism 34a opens the switch 34b, whereupon the energizing circuit 32 of the drive motor 33 is interrupted to stop the elevating and lowering mechanism 5.
  • FIG. 6c This instant is depicted in FIG. 6c.
  • the coil is located in axial alignment with the cones 6, 8 and consequently, the latter may be movedaxially towards one another to project into the central coil opening and to engage the coil on both sides without the danger of damaging the inner coil windings. Since the hoisting speed is independent from the weight of the coil due to the electrically or hydraulically operated drive means, the delay needed for the aforenoted additional upward travel of the hoisting trough carrying the sheet metal coil can be very accurately determined.
  • the coil holder assembly illustrated in FIG. 3 differs from that shown in FIGS. 1 and 2 only in that instead of cones 6 and 8 short-length, radially expanding cylindrical drums l4 and are used.
  • the loading step proceeds'in a manner identical to that described in connection with the embodiment shown in FIGS.'1 and 2.
  • the aforedescribed manner of controlling the loading process may also bepracticed with a coil holder which, according to FIG. 4, includes a long, radially expanding cylindrical drum 18.-Here the loading of the coil- 16 is-effected by means of a dolly 21 which is movable parallel to the axis of the coil holder and on which there is mounted a vertically movable hoisting trough 20.
  • a mirror 24 which reflects a light beam 25 emitted by an optical gate device 23, when the coil 16 is lifted by the hoisting trough 20 to such an extent that the light beam may pass through the central coil opening.
  • the optical gate device 23 is mounted on a displaceable upright 22 by means of which the device 23 inay be so adjusted that the light beam is aligned with the mirror 24 and thus travels coaxially with the holder'drum 18.
  • the sheet metal coil 16 situated on the hoisting trough 20 is transported on rails by means of the dolly 21 to the immediate vicinity of the holder drum 18. There the dolly 21 is stopped by a terminal switch, not shown. As the dolly 21 is arrested, the drive means for the displaceable upright -22 is, by means of a further switch, also not shown, energized for a duration until the upright 22 is in a position in which the light emitter of the optical gate device 23 is aligned with the axis of the holder drum 18. As the displacement of the device 23 is terminated, the hoisting of the coil 16 is started by the hoisting trough 16, actuated by a conventional and not illustrated follow-up control circuit. As soon as the light beam passes unobstructed through the coil opening, the timing relay associated with the optical gate device 23 becomes operational until the central position of the coil 16 is achieved, as it was discussed in connection with the embodiment according to FIGS. 1 and 2.
  • Follow-up controls may control the insertion of the coil 16 over the expanding drum 18. Similarly, the spreading of the expanding drum, the lowering of the hoisting trough, the withdrawal of the upright with the optical gate device and the reverse travel of the empty dolly 21 may also be controlled by the aforenoted follow-up controls. It is to be further understood that such follow-up controls may also find application in the embodiments discussed in connection with FIGS. 1-3.
  • the central coil openings will be different in diameter.
  • the central coil openings instead of two types of coil holders with different drum diameters only one coil holder is used that has a drum for the smaller coil opening.
  • an adapter is provided which is inserted on the holder drum.
  • the timing relay for each diameter of coil opening there are used permanently set separate timing relays.
  • a coil holder of the type that supports a coil of sheet material and has (a) a holder drum extending axially into the central opening of the coil for supporting the same, (b) a vertically movable hoisting trough for liftingsaid coil to the height of said holder drum and (c) a lifting and lowering mechanism for moving said hoisting trough, the improvement comprising,
  • An improvement as defined in claim 1 including a plurality of timing relays operatively arranged to constitute selectively and individually the first said timing relay, each of said timing relays being permanently set according to a determined, different diameter of said central coil opening for stopping the upward travel of said hoisting trough after a delay that permits, from the moment of the timing relay actuation, to lift said coil an additional distance equalling the radius of said center coil opening, only one of said plurality of timing relays being in circuit at any given time.
  • a coil holder of the type that supports a coil of sheet material and has (a) a holder drum extending axially into the central opening of the coil for supporting the same, (b) a vertically movable hoisting trough for lifting said coil to the height of said holder drum and (c) a lifting and lowering mechanism for moving said hoisting trough, the improvement comprising,
  • an optical gating device having 1. means emitting a light beam coaxially with said holder drum,
  • an adjustable time relay coupled from said reflex light beam device and responsive to signals therefrom, which relay controls the delayed'stopping of the hoisting of the coil in response to passing the light beam through the coil aperture;
