  • the invention relates to a material handling component for use in manufacturing. In one of its aspects, the invention relates to a material handler for perforated articles. In another of its aspects, the invention relates to an assembly for handling stacks of heat exchanger fins.
  • a plurality of fins is produced for attachment to looped tubing carrying a heat exchanger fluid.
  • the fins are produced from a sheet of stamped metal and are sheared from the sheet in rapid succession. Each fin has been perforated to include holes for receiving the tubing.

  • a fin stacker assembly includes a plurality of arranged vertical rods aligned for receiving fin sheets through holes formed therein.
  • the stacker is configured to receive multiple stacks of fins that are closely adjacent to each other.

  • the screw-adjustable legs 515 can be used to fix the altitude and the attitude of the receiving dock 12 .
  • the receiving dock 12 is thereby adjustable to the height and angle of the fin press/shear 15 .
  • the receiving dock 12 includes wheel stops 520 , lateral guide rails 525 , a cart lifting mechanism 530 , and a rod alignment lifting mechanism 19 (as described in the previous embodiments).
  • a proximity switch assembly 535 is provided to detect proper positioning of a cart 545 within the receiving dock 12 .
  • the proximity switch assembly 535 further includes an isolated spring pin 540 electrically connected to a control system 550 of the fin press/shear 15 .
  • the proximity switch assembly 535 further includes a threaded aperture 552 for receiving a proximity switch 553 ( FIGS. 17A, 17B ).
  • the proximity switch 553 is preferably a magnetic proximity switch and is positioned at the level of the base plate 355 to detect the presence of the cart 545 .
  • the receiving dock 12 is properly aligned with the fin press/shear 15 , it is set to receive the fin stacker assembly cart 545 .
  • the cart 545 is supported by a plurality of wheels 555 , generally positioned at the forward extent and the rearward extent of the cart 545 .
  • the fin stacker assembly cart 545 is of a fixed width so that as the cart 545 is rolled into the receiving dock 12 , the body of the cart is correctly positioned laterally by the lateral guide rails 525 .
  • the wheels 555 positioned at the forward extent of the cart 545 are positioned to engage the wheel stops 520 for establishing a longitudinally forward positioning of the cart 545 within the receiving dock 12 .
  • the proper forward positioning of the cart 545 will also enable an engagement of the isolated spring pin 540 by a contact plate 558 .
  • the contact plate 558 is attached to the cart 545 by an isolation mount 560 on the cart 545 .
  • the isolation mount 560 can be formed of nylon or Micarta® or other known non-conductive materials.
  • the control system 550 of the fin press/shear 15 Upon engagement of the proximity switch assembly 535 , the control system 550 of the fin press/shear 15 receives a signal from the proximity switch 553 , and activates the cart lifting mechanism 530 .
  • the cart lifting mechanism 530 comprises threaded body cylinders 532 positioned for engaging the corners of the cart 545 . The threaded body of the cylinders 532 provide for a pre-lift positioning, then the cylinder is activated ( FIGS. 15A, 15B ), i.e.
  • the lift rails 17 of the rod alignment lifting mechanism 19 are positioned to allow the tongues 447 to enter each rail 17 as the cart 545 is rolled into the receiving dock 12 .
  • Each rail 17 is further dimensioned to permit the raising of the cart 545 by the cart lifting mechanism 530 without the tongues 447 binding against the rails 17 .
  • the control system 550 After a suitable delay, such as two seconds, the control system 550 signals the rod alignment lifting mechanism 19 to activate so that the lift rails 17 engage the tongues 447 attached to the rod alignment plate 445 on the fin stacker assembly module 380 mounted on the cart 545 , and carry it to an uppermost starting position (shown as 17 ′).
  • the lifting mechanism 19 is further provided with upper and lower limit switches 565 , 570 ( FIG. 21 ) to signal the control system 550 when the lift rails 17 are in the uppermost and lowermost positions respectively.
  • the control system 550 will stop the lifting mechanism 19 and signal the operator that the fin press/shear 15 may be started or continue its production cycle. In a fully automated system, the control system 550 will directly control the fin press/shear 15 .
  • the fins (not shown) will be deposited on the rods 50 of the fin stacker assembly module 380 , and will settle onto the rod alignment plate 445 .
  • the control system 550 is configured to periodically activate the rod alignment lifting mechanism 19 to lower the alignment plate 445 .
  • control system 550 will lower the rod alignment lifting mechanism 19 a predetermined distance every one hundred cycles of the fin press/shear 15 in order to lower the stack of fins and expose the upper ends of the rods 50 to accept additional fins.
  • the magnitude of the predetermined distance and number of cycles can be varied as production conditions warrant.
  • the control system 550 is configured to lower the rod alignment lifting mechanism 19 continuously at a rate corresponding to the rate of production of the fin press and shear 15 , so that the upper ends of the rods are maintained in an exposed condition for receiving fins produced by the fin press and shear 15 .
  • Other forms of control devices such as rotary encoders may also be used to properly locate the rod alignment plate to press shear production.
  • the fin stacker assembly module 380 of the instant embodiment is mounted to the cart 545 by mounting rails 575 . More specifically, the mounting rails 575 each include a non-conductive member 580 forming a non-conductive barrier between the cart 545 and a conductive mounting block 582 . The fin stacker assembly module 380 is attached to the conductive mounting block 582 and is thereby isolated from electrical ground by the non-conductive member 580 .
  • the non-conductive member 580 can be formed of nylon or Micarta® or other known non-conductive materials. Necessarily, the tongues 447 or the lift rails 17 are also formed of a non-conductive material to electrically isolate the fin stacker assembly module 380 from the receiving dock 12 .
  • the fin stacker assembly module 380 is thereby electrically isolated from ground under normal operating conditions.
  • the contact plate 558 is electrically connected to the conductive mounting block 582 .
  • the isolated spring pin 540 of the proximity switch assembly 535 electrically connects the fin stacker assembly module 380 to the control system 550 through the contact plate 558 and electrical conductors (e.g. wires, not shown).
  • a fin will occasionally fail to properly align with the rods 50 , or will fail to be cleanly deposited by the fin press/shear 15 onto the rods 50 , becoming jammed or wedged between the fin press/shear 15 and the rods 50 .
  • a fin jammed between the fin press/shear 15 and the rods 50 continued operation of the fin press/shear 15 can cause further jamming and damage to the fin press/shear 15 and to the fin stacker assembly module 380 . As shown schematically in FIG.
  • the fin forms an electrically conductive path, completing a circuit between the control system 550 , through the isolated spring pin 540 and the fin stacker assembly module 380 to the ground defined by the fin press/shear 15 .
  • the control system 550 is configured to interpret the completed circuit as a jam and stop the fin press/shear 15 until the jam can be cleared, thus preventing damage to the fin stacker assembly module 380 or the fin press/shear 15 .
  • the rod alignment lift mechanism 19 will continue to lower the lift rails 17 until the lower limit switch 570 is activated.
  • the lower limit switch 570 will provide a signal to the control system 550 , which will subsequently stop production by the fin press/shear 15 .
  • the control system 550 will then activate the cart lifting mechanism 530 to lower the cart 545 onto its wheels 555 within the receiving dock 12 .
  • the cart 545 can then be rolled out of the receiving dock 12 by an operator and a fresh cart 545 with empty fin stacker assembly module(s) 380 can be rolled into the receiving dock 12 in its place. The above procedure is then repeated with each subsequent cart 545 .
