Definitions

  • Corrugator machines convert paper from a web roll into flat corrugated box blanks. Such corrugator machines have a number of sections for forming such box blanks, and the devices in these sections are driven in synchronism by a line shaft. in the herein apparatus the blanks discharged from the corrugator lengthwise are moved at right angles, then shingled and stacked.
  • the velocity of each of the steps in handling the sheets is co-ordinated for a relative speed ratio between the right angle take off of the sheets, the shingling and stacking, and is co-ordinated with the speed of the corrugator machine, through the line shaft in such a manner that when the corrugator speed varies, then the right angle Merrill D. Martin, 2 Mail Court, Oakland,
  • V is the speed of the corrugator in ft/min.
  • V is the speed on the right angle take off.
  • W is the width and L is the length of the blank.
  • V is the speed of the stacker conveyor in ft/min and S, is the ratio of the shingle on the stacker.
  • a device is provided for adjusting the ratio of the respective conveyors to predetermine the speeds of the conveyors relatively to the speed of the corrugator in accordance with the width and length of the blanks.
  • a connection is provided to the line shaft of the corrugator so as to automatically control the overall speed in accordance with the variation of speed of the corrugator but maintaining the predetermined relative ratios between the respective conveyors.
  • a further object of the invention is to provide a method and apparatus whereby socalled multiple-outs" can be mechanically stacked at the highest corrugator speeds and with about the same efficiency as "one-outs. Namely, when the sheet in the corrugator is cut into several strips discharged simultaneously from the corrugator, then if they are of equal width they can be handled simultaneously, and if they are of different width, then they can be handled separately in this system.
  • a feature of the invention is that a single operator can handle the entire system and the labor required is minimal, and by reason of the particular arrangement of a right angle take off, and the transfer device or conveyor and the stacker, the relative speed between these steps can be pre-determined and maintained although the overall operation is controlled by and conforms to the speed in the corrugator.
  • FIG. 1 is a perspective view of the arrangement of the double system of conveyors for handling the sheets from the corrugator to stacking.
  • FIG. 2 is a somewhat diagrammatic side view of the intake side of the conveyor system.
  • FIG. 3 is a diagrammatic view illustrating the connection between the corrugator line shaft and the individually adjustable fluid motor drives for the elements of the conveyor system.
  • FIG. 4 is a diagrammatic view illustrating another form of connection between the corrugator line shaft and the fluid motors.
  • FIG. 5 is a diagrammatic view showing the connection between the corrugator line shaft and electric motor drive for the respective conveyors.
  • the delivery end I of the corrugator machine has discharging conveyors 2 and 3 respectively adjacent to the knives 4 and 5, whereby the blanks cut by the knives are discharged from the corrugator.
  • the blanks are discharged from the lower discharge conveyors 3 directly on to a right angle take off 7 whereby the sheets are advanced at right angles widthwise on to a transfer conveyor 8 and to a stacker conveyor 9 by which latter the blanks are stacked into stacks 11 on a conveyor [2.
  • the upper discharge conveyors 2 discharge the blanks lengthwise on to a longitudinal delivery conveyor 13 which in turn delivers the blanks on to a more distant right angle take off 14, which in turn delivers the blanks on to another transfer conveyor 16 which in turn properly shingles and transfers the blanks on to another stacker conveyor 17 to form stacks on a pallet.
  • Each of these conveyors in this system is driven by separate driving means.
  • a fluid motor 18 drives the right angle take off 14; another fluid motor 19 drives the transfer conveyor or shingling conveyor 16 and a third fluid motor 2! drives the stacker conveyor 17.
  • variable volume pumps 22 each connected to the respective fluid motors l8, l9 and 21 whereby the individual relative speeds of the right angle take off conveyor, the transfer conveyor and the stacking conveyor can be adjusted to a predetermined ratio, but all three variable volume pumps 22 are driven through a transmission 23 by the line shaft 24 of the corrugator indicated in FIG. 3.
  • variable speed electric motor 26 is interconnected between the three variable volume pumps 22 heretofore described and a tachometer control 27 for the electric motor 26, and the tachometer control is driven through the transmission 23 by the corrugator line shaft 24.
  • electric motors 28, 29 and 31 respectively drive the right angle take off 7 transfer or shingling conveyor 8 and stacking conveyor 9.
  • the electric motors 28, 29 and 31 are connected to a suitable ratio control 32, for instance of a rheostat type, and are ultimately controlled by the tachometer control 27 driven by the corrugator line shaft 24 as heretofore described.
  • the blanks may be shingled initially on the right angle take off. If the speed of the transfer conveyor 8 or 16 respectively is the same as the speed of delivery of the right angle take off, then there is no change or forming of a shingle on the transfer conveyors. Relative increase of the speed of the transfer conveyor will shorten the overlap and relative decrease of the speed of the transfer conveyor will increase the overlap.
  • the basic equation for the speed of the transfer conveyor is F M r) in which V, is the speed of the transfer conveyor in ftlmin and S, is the ratio of the shingle on
  • the relative speeds of the conveyors can be adjusted in accordance with the ratio of width and length of the blank as well as the ratio of shingle desired. As heretofore described, once this ratio is established, the ratio of speeds remains constant although the speed itself will change as controlled by the corrugator line shaft.
  • Each right angle take off conveyor is provided with power rollers 33, and also with a transverse series of back stops 34 resiliently mounted and balanced on a cross frame 36 which is adjustable longitudinally along the power rollers 33 to a distance corresponding to the length of the blanks discharged on to the power rollers 33.
  • the speed of the right angle take off rollers 33 can be so adjusted that each sheet advances widthwise to the point where the adjacent sheet discharged will land directly on top of the preceding one in sequence. This permits the sheets or blanks to be handled in groups or piles of two superimposed blanks when running "two-out or three superimposed blanks when running three-out,” and so on.
  • the transfer conveyor or shingling conveyor drive speed is set somewhat lower to establish the initial shingle between the blanks or between the groups of blanks.
  • the belt conveyors of the stacking conveyor 9 are adjusted normally slightly faster than those on the transfer conveyor so as to pull the lower blanks or sheets of each pile somewhat faster than the upper blanks and thereby to form a more uniform shingle between the individual sheets.
  • the sheets or boards are delivered to the stacker at intervals predetermined by the width of the sheet or board so that a proper shingle or overlap is established, whereby the sheets are maintained in proper order during the movement of the stacker.
  • the surface velocity of the stacker in these adjustments is less than the surface velocity of the continuous side delivery.
  • the ratio of velocity is maintained, although the various conveyors conform to variations of speed of the corrugator, for instance, while the corrugator is slowed down while making splices of web rolls, or when wet paper is run through the corrugator, or when extra large sheets are run.
  • the continuous sheet unrolled from the web roll is slit into width of the boxes to be made and then passed to the knives to be cut to length, and then ejected or discharged from the corrugator.
  • the velocity of the corrugator is proportional to the number of sheets cut to the desired length per minute. indicated by the formula of f V /L, wherein fc is the frequency of cut.
