Definitions

  • the present invention relates generally to the field of apparatus for separating paper or cardboard articles, such as cards, puzzles, and the like, from die-cut sheets, and more particularly to an apparatus for separating stacks of cards and the like from lifts of die-cut sheets.
  • scrap It is necessary to remove the individual cards from the rest of the sheet, which is called scrap.
  • a worker manually removes the cards from the scrap by beating on the cards with a hammer to break the nicks and push the cards through the sheet.
  • the current manual method for breaking cards from scrap is expensive in terms of labor costs. Additionally, the manual breaking of cards from scrap is hard physical work and may subject a worker to risk of injury. It is an object of the present invention to provide an automated system for breaking cards from scrap that overcomes the shortcomings of the prior art.
  • the present invention provides an apparatus for removing stacks of articles, such as cards, from lifts of die-cut sheets.
  • the apparatus of the present invention includes a lift support positioned to support a lift of die-cut sheets and at least one vibratory hammer mounted for movement toward the lift support to remove a stack of articles from the lift.
  • the apparatus of the present invention includes an array of hammer assemblies, in which each vibratory hammer is moved toward the lift support by an actuator supported by a hammer support carriage.
  • each of the vibratory hammers is individually actuated to move toward the lift support.
  • Apparatus 11 includes a table-like support structure 13 that may be positioned preferably near a die-cut press.
  • Support structure 13 supports a horizontal female die 15 and a pair of horizontally spaced apart support rails 17.
  • Female die 15 is adapted to support a lift 19 of die-cut sheets.
  • a lift 19 is a stack of one hundred fifty to two hundred individual die-cut sheets.
  • a sheet of lift 19 includes a plurality of die-cut cards 21.
  • the cards are printed with text and graphic information in a large printing press and are then processed with a die-cut press.
  • the die-cut press cuts through and around most of the periphery of the cards, but leaves nicks that retain the cards in the non-card portion of the sheet, which is referred to as scrap 23.
  • apparatus 11 of the present invention is adapted to remove stacks of cards 21 from scrap 23.
  • female die 15 includes a plurality of windows 25 positioned to correspond with cards 21. Windows 25 are slightly larger than cards 21 so that stacks of cards may pass therethrough.
  • female die 15 is made from a sheet of plywood, or the like, to fit a particular layout of cards on a sheet. Alternatively, the female die may be configurable for different card and sheet layouts. Appropriate guides or stops (neither shown) may be provided to aid in registering lift 19 with female die 15. Another function of female die 15 is to maintain the scrapped cards in a neat stack. Guides (not shown) may be attached to the lower side of female die 15 to ensure that multiple stacks of cards are stable and do not topple.
  • a set of horizontally extending spaced apart finger bars 26 is supported for horizontal movement with respect to female die 15. Finger bars 26 are attached to a moveable fingerboard 28 and pass through a bar 30 positioned adjacent female die 15. Prior to placing a lift 19 on female die 15, finger bars 26 are moved, either manually or automatically, over female die 15. The lift is then placed on finger bars 26. Finger bars 26 prevent sagging of the lift and protect female die from damage during loading of the lift. Finger bars 26 are then retracted to allow lift 19 to settle onto female die 19, as shown in Figure 1.
  • rails 17 support a hammer support carriage, designated generally by the numeral 31.
  • Hammer support carriage 31 includes a hammer support plate 33 positioned between roller supports 35.
  • Roller supports 35 include rollers that engage longitudinally extending grooves formed in support rails 17 so that hammer support carriage 31 may be moved, manually or automatically, longitudinally back and forth along rails 17.
  • Hammer support plate 35 supports an array of hammer assemblies 41.
  • Each hammer assembly 41 includes a pneumatic linear actuator 43 and a pneumatic vibratory hammer 45.
  • Both pneumatic linear actuators and pneumatic vibratory hammers are generally well known in the art.
  • Pneumatic linear actuators 43 are adapted to extend and retract under the influence of air supplied through appropriate ducting (not shown for purposes of clarity of illustration).
  • vibratory hammers 45 are supplied with air through appropriate ducting (not shown for purposes of clarity of illustration) to provide rapid, short stroke, reciprocating blows through a hammer tip 47.
  • An example of a vibratory hammer that may be used according to the present invention is the Model AH-15 Auto Hammer® available from Danair, Inc. of Visalia, California.
  • the Model AH-15 Auto Hammer® operates at 50-125 psi and consumes 2-4 cubic feet per minute (CFM) of air to provide a hammer stroke rate of over one thousand blows per minute.
  • CFM cubic feet per minute
  • Hammer assemblies 41 are positioned on hammer support plate 33 such that they may be actuated to move through lift 19 to remove stacks of cards 21.
  • hammer assemblies 41 are supplied with air and actuated in groups.
  • the groups or hammer assemblies 41 may be actuated sequentially or in multiple groups, depending upon the available supply of air.
  • Hammer support carriage 31 is moveable, either manually or automatically, longitudinally along rails 17 from the position shown in Figure 1 directly above lift 19 and female die 15 to a position (not shown)toward end 52 of rails 17, in which a lift 19 may be placed upon female die 15. Stops 51 are provided at the ends of support rail 17 to limit the rightward travel of support carriage 31.
  • Apparatus 11 includes a wheeled pallet 53 that is supported below female die 15 by a scissors jack arrangement 55. Jack is movable up and down by a suitable mechanism, as is well known in the art. Pallet 53 is adapted to catch multiple stacks of cards removed by the action of vibratory hammer assemblies 45. Pallet 53 is initially supported by jack 55 closely below female die 15. Jack 55 is lowered after each cycle of hammer assemblies 45 to make room for another stack of cards. After a selected number of cycles, jack 55 is operated to lower pallet 53 to the floor, where pallet 53 may be wheeled away and another pallet may be wheeled into position.
  • hammer assemblies 43 are all actuated to their retracted position and hammer support carriage is moved to the leftward end 52 of support rails 17 while finger bars 26 are moved over female die 15. Then, a lift 19 is positioned upon finger bars 26. Finger bars 26 are then retracted to allow lift 19 to rest on female die 15 and hammer support carriage is moved back to the position shown in Figure 1, and preferably locked in place by pneumatic cylinders (not shown). Jack 55 is actuated to raise pallet 53 to a position immediately beneath female die 15. Preferably, lift 19 is clamped to female die 15 by horizontal bars actuated by pneumatic cylinders (neither shown).
  • hammer assemblies 43 are appropriately actuated, either simultaneously, or sequentially, to remove stacks of cards 21 from the scrap.
  • hammer assemblies 43 are actuated to the retracted position and hammer support carriage 31 is retracted. The scrap is removed, finger bars 26 are extended, and jack 55 is lowered. Apparatus 11 is then ready for another cycle.
  • the apparatus of the present invention provides an automated system for dividing stacks of cards from the die cut scrap matrix automatically.
  • the apparatus of the present invention separates cards from scrap more efficiently than the prior art manual method with reduced labor costs.
