Definitions

  • a slotting mechanism comprising a pair of parallel, spaced rotatable shafts on which there are mounted lengthwise spaced pairs of coacting slotting heads between which the paperboard is fed.
  • the upper one of the pairs of slotting heads is usually provided with two radial spaced cutting blades and the lower head is formed with a peripheral groove which receives the cutting edge of the blades.
  • One blade cuts a slot in the leading edge and the other blade cuts an equal length slot in trailing edges of the blank. These slots define the flaps which are later folded over and form the top and bottom of the container.
  • the blade carrying head has been constructed such that one blade is fixed thereon and the other blade is angularly adjustable relative to the fixed blade by varying the central angle of the circular sector of the bladecarrying head between the fixed and movable blades. In this manner the slot lengths in the leading and trailing edges are adjusted to the desired and selective lengths.
  • the usual slotting mechanism includes five pairs of heads of which the three intermediate pairs are employed to form the slots defining the flaps.
  • relative blade angle (circular sector) between the fixed and movable blades of the three upper heads must be maintained equal on each of the heads such that all three slots cut in the leading edge or in the trailing edge of the paperboard blank will be of equal length.
  • the adjustment of the blade angle has been made on each of the heads individually.
  • Such individual adjustment because of human error, often times resulted in heads having different blade angles such that different length slots were formed in the blank. Furthermore, the individual adjustment required that the machine be shut down before it could be made.
  • the invention comprises generally a rotatable shaft, a plurality of blade heads mounted on said shaft, each of said heads including a blade fixed thereto and a blade adjustably mounted on said head and angularly spaced from said fixed blade relative to the center of the blade head, and means for simultaneously moving each of said Accordingly, the
  • FIGURE 1 is a fragmentary view of a slotting mechanism embodying the invention with certain of the parts shown in cross section.
  • FIGURE 2 is an enlarged view, partially in cross section, of the movable blade registering device shown on the right side of FIGURE 1.
  • FIGURE 3 is an end view of the blade head taken substantially along the lines III--III of FIGURE 1.
  • FIGURE 4 is a cross section view of the blade shaft running register.
  • FIGURE 5 is a view taken substantially along the lines V--V of FIGURE 2 showing the floating disc driving structure of the movable blade registering device.
  • FIG. 10 there is shown a slotting mechanism 10 embodying the present invention for varying the angularity between the blades on the cutter heads.
  • the slotting mechanism 10 comprises a plurality of coating cutting or slotting heads including cutting or blade heads 11 which are mounted for rotation on a shaft 13 suitably journaled adjacent each end in frame members 15. Blades 17' and 19 carried on the blade heads 11 coact with aligned lower female heads 21 rotatable with a rotatable lower shaft (not shown) parallel to the shaft 13.
  • the slotting shafts are driven by a main drive geartrain of which the gear 12 for driving the shaft 13 is shown.
  • the female heads are formed with a peripheral groove 23 which receives the end of the blades 17 and 19 such that when the paperboard blank passes therebetween one of the blades is operative to slot the leading edge of the blank and the other of the blades is operative to slot the trailing edge of the blank.
  • FIGURE 1 In the formation of a blank for forming cartons or boxes it is conventional to employ three of such slotting heads, of which two are shown in FIGURE 1.
  • the heads are spaced longitudinally along the length of their respec tive shafts in accordance with the dimensions of-the box to be formed.
  • the slots in the leading and trailing edges of blank are equal length and the length is determined by the size box to be formed;
  • the slots define the flaps forming the top and bottom of the container.
  • each of the blade heads 11 with a hub 24 having intermediate the ends thereof an upstanding peripheral flange 25.
  • the hub is suitably held for rotation with the shaft 13 by a key (not shown) and against lengthwise movement by a set screw 27.
  • the blade 17 is mounted on one face of the flange 25 as by screws 29. In this manner the blade 17 is fixed for rotation with respect to the shaft 13.
  • a gear 31 formed of a plurality of arcuate segments 33 which are joined together by splicing plates 35.
  • the face 36 is formed with an axial cut out 37 which receives the peripheral flange 25 such that the face 36 lies in the same plane as the outer side of the flange.
  • Fixed to the face 36 as by screws 38 is the movably mounted blade 19.
  • Changing of the angular position of the adjusting shaft 43 with respect to the shaft 13 also turns the gear 39 fixed to the former a corresponding amount.
  • Such turning of the gear 39 causes the blade carrying gear 31 meshing therewith to turn about the hub 24 fixed to the shaft 13 and carrying the fixed blade 17. In this manner the angular relationship between movable blade 19 and the fixed blade 17 is changed.
  • a device commonly known in the art as a running register is employed to shift the angularity of the adjustment shaft 43.
  • the running register 45 comprises a sleeve 47 turnably supported adjacent the terminal end of the adjustment shaft 43.
  • the sleeve 47 is seated on the outer face of bearings 49 fixed on the shaft 43. Suitable means such as snap rings or the like may be employed to hold the sleeve against axial movement.
  • One end 51 of the sleeve is formed concentric with the shaft 43 and the other end 53 is formed eccentric thereto.
  • a supporting disc 57 mounted on bearings 55 held fast on the concentric portion 51 is a supporting disc 57 on the face of which there is fixed as by screws an annular internal gear 59 having external gear teeth 61 meshing with a drive gear 63 fastened to the end of the blade shaft 13.
  • a spur 67 having fewer teeth (FIGURE than the number of teeth on the internal gear 65.
  • the alteration of the angularity of the meshing engagement will hereinafter be re? ferred to as the phase shift.
  • the phase shift of the spur gear 67 with respect to the internal gear 59 is made by angular adjustments on the eccentricity of the eccentric portion 53 of the sleeve 47. Such adjustment may be made while the machine is running or stopped.
  • a hand wheel 69 fixed to one end of a shaft 71 which is suitably journaled in the frame member and an enclosure bell 73.
  • a pinion 74 meshing with a spur gear 75 fastened as by screws to the end of the sleeve 47.
  • the pinion gear 74 turns spur gear 75 and thereby the sleeve 47 which as previously described is turnably supported on the shaft 43 In this manner the angle of eccentricity of the eccentric portion 53 with respect to the shaft 43 is varied and a corresponding phase shift of the spur gear 67 relative to the internal gear 65 results.
  • This phase shift is transmitted to the adjusting shaft 43 and the gears 39 fixed thereto by way of a coupling mechanism (FIGURES 2. and 5) comprising a floating disc 77 having open-ended slots 79 receiving driving studs 81 carried by the spur gear 67.
  • a coupling mechanism (FIGURES 2. and 5) comprising a floating disc 77 having open-ended slots 79 receiving driving studs 81 carried by the spur gear 67.
  • Fixed to the shaft as by a set screw is a driving disc 83 having fixed thereto inwardly projecting studs 85 engaging within open-ended slots 87 which are degrees out of phase with the slots 79.
  • the adjusting gears 39 meshing with the movable head gears 31 turns about the hubs an amount corresponding to the phase shift.
  • the blades 19 carried on the gears 31 are rotated relative to the blades 17 mounted on the hubs 24 which are fixed to the blade carrying shaft 13 for rotation therewith.
  • the blade shaft running register is similar to that described above in connection with the adjusting shaft register 45 and comprises a turnable sleeve 87 having a concentric portion 89 on which there is rotatably mounted an annular internal driven gear 91 having external gear 93 which meshes with drive gear 12 of main gear train.
  • Rotatably mounted on an eccentric portion 95 is a spur gear 97 having a lesser number of teeth than the internal gear such that a phase shift may be made upon turning of the sleeve 87.
  • the sleeve is turned so as to vary the degree of eccentricity and thereby the phase shift by a hand wheel 99 fixed to one end of the shaft 101 on the other end of which there is fastened a gear 163 meshing with an idler gear 105 which meshes with a gear 107 fast to the sleeve 87.
  • the phase shift between the annular gear 91 and the spur gear 97 is transmitted by way of a coupling device 109 comprising a floating disc 111 driven by way of studs 112 projecting from the annular gear 97 and a hub 113 keyed to the shaft 13.
  • a coupling device 109 comprising a floating disc 111 driven by way of studs 112 projecting from the annular gear 97 and a hub 113 keyed to the shaft 13.
  • Driving the hub 113 and thereby the shaft 13 are pins 115 (not shown) which seat within the open-ended slots of the floating disc 111.
  • the angle of eccentricity of the eccentric 95 supporting the spur gear 97 is altered by adjustment of the hand wheel 99. This adjustment results in a phase shift between the spur gear 9''] and driving gear 1 and a corresponding phase shift with respect to the driving gear 12. Hence the blades 17 which are fixed relative to the rotating blade shaft 13 are also shifted thereby to vary the length of the slot.
  • said at least one head including (1) a hub affixed to said first shaft for rotation therewith,
  • first means supported on said hub for mount ing said second blade on said hub in rotatable relationship thereto in circumferential spaced relation to said first blade and (5) an external gear formed -on said first means and concentric therewith,
  • the slotting mechanism of claim 1 including (it) a driving gear for said continuously rotatable first shaft.
