Definitions

  • the sheet feeding apparatus of the present invention is particularly applicable for use with machines such as folder-gluers, printer-slotters, etc., where blanks must be fed in timed sequence through a series of operations.
  • Standard feeding heretofore has been one blank per machine cycle or one blank for every other machine cycle. Quite often the size of the blank will enable the feeding to be accomplished in a more rapid manner whereby it would be desirable to feed two blanks per cycle, thereby increasing machine output and flexibility.
  • Feeding blanks from a hopper in timed sequence requires a reciprocating element whose characteristics are such that a blank is started from rest and accelerated up to machine board speed at approximately the middle of the forward stroke.
  • a reciprocating element whose characteristics are such that a blank is started from rest and accelerated up to machine board speed at approximately the middle of the forward stroke.
  • variable velocity mechanisms such as inverted slider crank mechanisms, elliptical gears, draglink mechanisms, etc.
  • the solution to the problem of feeding two blanks per machine cycle is not accomplished by merely increasing the input speed to the reciprocating element due to the fact that the blanks must be fed to feed rollers at the surface speed of the feed rollers. If the speed of reciprocation of the reciprocating elements were doubled, so as to deliver or feed two blanks per machine cycle, the blanks will not be traveling at the surface speed of the feed rollers when contacting the same.
  • the apparatus of the present invention is structurally interrelated in a manner so that the blanks or sheets are fed to the feed rollers at substantially the same surface speed of the feed rollers.
  • the blanks are fed from a hopper by a reciprocating slide means connected to a rotating shaft by mechanical linkages.
  • FIGURE 1 is a partial side elevation view of a printerslotter connected to a multistage rescoring and gluing section on a folder-gluer for processing blanks of paperboards.
  • FIGURE 2 is a schematic perspective view of the components of the feeding apparatus of the present invention.
  • FIGURE 3 is a schematic illustration of a conventional quick return mechanism used for feeding blanks.
  • FIGURE 4 is a velocity diagram.
  • FIGURE 5 is a partial plan view of a portion of the apparatus in FIGURE 2.
  • FIGURE 6 is an elevation view of the apparatus in FIGURE 5.
  • FIGURE 1 a printer-slotter designated generally as 10.
  • the printerslotter 10 includes a feeding section 12, printing sections designated as 14, and a slotting-scoring section designated as 16.
  • the printer-slotter 10 is connected to a multistage rescoring and gluing section 18 of a folder-gluer 20.
  • FIGURE 1 will process paperboard blanks as follows. Paperboard blanks 28 are fed from a hopper 30 by means of a reciprocating slide 32 to the feed rollers 24 and 26. The feed rollers 24 and 26 feed the blanks to a printing roller 22 of the printing section 14. Printing section 14 may have one or more printing rollers in series depending upon the number of colors to be printed on the paperboard blank 28. Thereafter, the blank passes section 16 where it is slotted and scored and fed to section 18. In section 18, the blank is rescored and glue is applied to a glue flap. From section 18, the thusly processed blank is fed to the folder-gluer 20 which folds the blank so that the glue flap along one edge of the blank is in contact with the opposite edge so as to form a folded paperboard or cardboard box.
  • the Whitworth quick return mechanism 36 as diagrammatieally illustrated in FIGURE 3 includes an arm rotatable about point D and connected to a disk rotating about point C by way of a slide on the arm rotatably connected to the disk at a distance radially outwardly from the point C. With the disk rotating in the direction of the arrow in FIGURE 3, the slide 32 will have a forward stroke from point B to point A and a return stroke from point A to point B.
  • the dimensions of the components and the relationships are chosen in a manner known to those skilled in the art so that the blank 28 will be fed to the feed rollers 24 and 26 so that the blank will be traveling at a velocity corresponding to the surface speed of the feed rollers when contact therebetween is made.
  • FIGURE 3 when constructed to feed blanks 28 to the feed rollers 24 and 26 at a rate of one blank per revolution of the printing roller 22 cannot be utilized to feed two blanks per revolution of the printing roller 22 merely by doubling the speed of rotation of the disk having the point C for its center. The reason being that the blanks 28 will no longer contact the feed rollers 24 and 26 at the surface speed of these rollers.
  • FIGURE 2 there is illustrated a sheet feeding apparatus which will enable the blanks 28 to be fed from the hopper 30 to the feed rollers 24 and 26 at a rate of one blank per revolution of the roller 22 or two blanks per revolution of the roller 22, while maintaining the relationship that the blanks must pass between the feed rollers at the same surface speed of rotation of the feed rollers 24 and 26.
  • the slide 32 will be mounted and supported by structure not shown so that it may reciprocate in the direction of the arrow 34.
  • the connecting rod 38 is rotatably connected at one end to the slide 32 and at its other end to a feed lever 40.
  • the feed lever 40 is fixedly secured to a rocker shaft 42.
  • a yoke 44 having arms 46 and 48 is also fixedly secured to the rocker shaft 42.
  • a pin 50 extends into the gap between the arms 46 and 48. Pin 50 is integral at one end with a disk 52 on shaft 53. Pin 50 projects in an axial direction with respect to shaft 53 and is at a location which is intermediate to the periphery and center of disk 52.
  • a gear 54 is free-wheeling on shaft 53. That is, gear 54 is not directly connected to shaft 53.
  • Gear 54 is in meshing engagement with gear 56 on shaft 58.
  • Shaft 58 may also be the shaft on which the lower feed roller 26 is supported.
  • the gear 60 on shaft 58 is in meshing engagement with a gear 62 on the shaft 61 for the upper feed roller 24.
  • Shaft 61 is preferably provided with a flexible coupling 63 between gear 62 and feed roller 24 so as to permit adjustment of the gap between the feed rollers.
  • Gear 62 is in meshing engagement with a gear 64 which in turn is in meshing engagement with gear 66 on shaft 68.
  • Shaft 68 may be the shaft on which the printing roller 22 is supported.
  • Shaft 68 may be driven by a motor 70.
  • the remainder of the gear train or transmission means which facilitates driving the remaining rollers as well as the main drive shaft 72 for the folder-gluer 20 are not shown and may be operatively coupled to shaft 68 for a driven relationship for motor 70. It will be obvious that the motor 70 may be coupled into the system in any one of a variety of locations and need not be coupled directly to the shaft 68 as illustrated.
  • the main drive shaft 72 of t the folder-gluer 20 is in driving relationship with a shaft 74 which extends the length thereof so as to facilitate transmission of rotary power to the end of the foldergluer not shown.
  • a gear 76 is mounted on shaft 58 for rotation therewith.
  • Gear 76 is in meshing engagement with gear 78 which in turn is in meshing engagement with gear 80.
  • Gear 80 is free-wheeling on shaft 53 and spaced from gear 54.
  • a clutch 82 is reciprocally supported on shaft 53 and connected thereto by a key 84.
  • Clutch 82 has a radially outwardly directed flange 86.
  • a pin 88 extends in an axial direction from the clutch 82 in opposite directions therefrom. Pin 88 is adapted to be selectively inserted into hole 90 on gear 54 or hole 92 on gear 80.
  • the clutch 82 is illustrated in FIGURES 2 and as being in a mid-position which may be considered neutral.
  • gear 54 will then be coupled to drive shaft 53 in the direction of the arrow superimposed on gear 54 in FIGURE -2.
  • gear 80 will be coupled to drive shaft 53 in the direction of the arrow superimposed on gear 80 in FIGURE 2.
  • lever 96 and clutch 82 may be prevented from staying in a neutral position by a detent mechanism not shown.
  • FIGURE 5 there is illustrated a portion of the wall 94 for the housing which will enclose gears 54, 56, 76, 78 and 80.
  • a lever 96 is provided to selectively actuate the clutch 82.
  • Lever 96 is suitably journaled in wall 94 for oscillating movement.
  • Lever 96 terminates in a yoke 98 which embraces the flange 86 on clutch 82.
  • a window 100 having a line 104 thereon is provided in the wall 94 opposite the gear 80.
  • a similar window 102 having a line 106 thereon is provided in the wall 94 opposite the gear 54.
  • a line (not shown) is provided on the periphery of gears 54 and which will be superimposed behind the lines 106 and 104, respectively, in one rotative disposition of the gears 54 and 80. Since the gears 54 and 80 need only be rotated less than 180 in order to cause the lines thereon to be superimposed over the lines on the windows, a detachable handwheel 108 may be provided on shaft 58. Handwheel 108 provides a convenient means for causing the gears 54 and 80 to rotate in opposite directions through an arc of less than 180. Accordingly, any other equivalent device or means for causing such rotation may be utilized.
  • the size of disk 52 is chosen so that the length of the stroke of slide 32 will be approximately two-thirds the diameter of roller 22.
  • the radial distance between the longitudinal axis of shaft 53 and pin 50 is chosen so as to be approximately one-third the distance between the longitudinal axes of shafts 53 and 42.
  • the maximum instantaneous velocity of the slide 32 on its return stroke will be one-half the maximum instantaneous velocity of the slide 32 on its forward stroke.
  • rotation of shaft 53 in an opposite direction at twice the speed will result in the slide 32 attaining the same maximum forward velocity which will correspond to the surface speed of the feed rollers 24 and 26.
  • FIGURE 4 is a diagram illustrating the instantaneous velocities of the slide 32 as a function of the stroke.
  • point A represents the forward portion of the stroke for slide 32 and point B represents the back portion of the stroke for slide 32.
  • the instantaneous velocity of the slide 32 is represented by line 110 indicative of the feed stroke of the cycle.
  • the return stroke of the cycle is represented by line 112.
  • the instantaneous forward velocity of the slide 32 will correspond to line 111 and the instantaneous velocity of slide 32 on the return stroke will follow line 114.
  • the instantaneous velocities represented by lines 110 and 111 need not be identical curves as shown in FIGURE 3, they are required only to be similar to each other so that the velocity relationship between blanks 28 and feed rollers 24 and 26 be maintained. On a velocity-time diagram, the lines 110 and 114 would be repeated twice during the time required for one complete revolution of the roller 22.
  • the feed rollers 24 and 26 feed the blank 28 to the printing roller of a printer-slotter. It will be obvious to those skilled in the art that the feed rollers 24 and 26 may be associated with a device other than a printer-slotter or printing roller 22. That is, the feed rollers 24 and 26 may feed the blanks directly to a rotating member of a folder-gluer, or some other mechanism which will further process the blank 28.
