Definitions

  • This invention has reference'to apparatus forfeeding blanks of cardboard or analogous sheet material to machiueryfor operating on-the blanks so fed, incorporatinglone or' more longitudinally arranged feed members which are reciprocably mounted in the bed of the apparatus on which the stacks of cardboard or-analogous sheet material to be fed are placed preparatory to being fed to the machinery for performing the'subsequent op eration or operations, a chamber which may be put into communication with the space or spaces below the bottom of the stack when the stack of blanks to befed is placed on the feed members, means for maintaining sub atmospheric "pressurewithin said chamber and valve means for controlling the opening and closing of the communication opening
  • the invention also resides in' associating with the" reciprocatory feed members spaced transverse upstanding portions so that the lowermost portions of the sheet to be fed tend to droop within upstanding transverse portions to ensure a positive'feeding.
  • the invention further resides in apparatus for feeding blanks of cardboard or analogous sheet material to machinery for performing subsequent operations 'on the fed blanks constructed, arranged and adapted for use substantially as will be'clescribe'd hereinafter.
  • BACKGROUND apparatus in which thelowermost sheet of a stack f blanks is fed' through the agency .of suction means into the-spaces" between 'adj'acent the nip of rolls for conveyance to the machinery on which the subsequent'ope'rations are to be performed.
  • the present invention has forits object to provide' apparatus operating through the-agency of suction which it is considered is simpler in construction and manner of operation and more economical to produce than suction for-the present application is claimed as -of the said date.

  • each slideway 111, 112, 113, 114 Disposed within each slideway 111, 112, 113, 114 is a channel section member 12 hereinafter termed feed tuberant portions 131 which are proud of the plane of the feed bed 11.
  • the spaces 12a' intermediate the bridging members 13 are adapted to be filled by removable filler blocks 14 which are shallowerthan the protuberant portions 131 of the bridging members 13.
  • the bed 11 is provided at the rear with the customary upstanding adjustable abutment bar 15 for locating'the rear end of the stack 16 I boards to 'befed.
  • the front edges of the stack 16 of boards abut adjustable feed gates 17 and the corners of the stack 16 are stabilised by adjustable vertical angle section members 161.
  • the feed members 12 are adapted for I reciprocation through the agency of links 18 and rockers 19 mounted on a transverse rock shaft 20 adapted to be driven by an electric motor 21 through chain gearing 22 an d pinions 23 the rock shaft 20 and hence the rockers 19 being actuated through the agency of eccentrics '191 and"rock'er arms'192' driven from a stub shaft 201 I terfiy valve242a'for determining the amount of suction tobe induced by the fan 243';
  • bridging members 13a provided with permanently open elongated transverse slots 132 which are permanently open to the hollow interiors of the feed members 12 for permitting suction to be maintained on the underside of the forepart of the lowermost board of a stack 16.
  • the chamber 24 also has communication by Way of a longitudinal length of hose 244 with a vertical hollow member 25 hereinafter termed the auxiliary duct 25 the mouth of which opens into the bed 11 in front of the adjustable feed gates 17 for pulling the front of the board below the gates 17 as will be referred to hereinafter.
  • auxiliary duct 25 Disposed within the mouth of the auxiliary duct 25 are four freely rotatable wheels 251 the peripheries of which are tangential to the plane of the feed bed 11.
  • a plate valve 26 Disposed within the lower portion of the auxiliary duct 25 is a plate valve 26 which can be operated by means of a rod 261 to adjust the degree of vacuum induced in the auxiliary chamber 25.
  • the stack of boards 16 to be fed to the rotary cutting and/or creasing rolls 103 and 104 is stacked on top of the feed bed 11 with the rear edges of the boards of the stack in abutment with the adjustable abutment bar 15 and the front edges of the boards in the stack 16 in abutment with the adjustable gates 17 and the corners embraced by the corner guards 161.
  • the adjustable gates 17 are set so that there is a gap 17A between the knife-edged bottom of the gates 17 and the surface of the bed 11 very slightly in excess of the thickness of the boards in the stack 16. Before the boards are loaded onto the bed 11 filler blocks 14 may be removed from the spaces 12a between adjacent bridging members 13 according to the nature of the boards in the stack 16.
  • the feed members 12 occupy the rearmost position with the gaps 121 in the connecting limbs 122 in full register with the chamber 24 see FIGURE 3.
  • the feed is initiated by starting the motor 24a to induce a vacuum in the chamber 24 and hence exerting a suction influence which is exerted on the underside of the lowermost board in the stack 16 through the gaps 12a between the upstanding portions 131 of the bridging member 13 bounding the spaces urrcovered by the removal of filler blocks 14.
  • the elongated openings 132 at the front of the feed members 12 cause a permanent suction effect to be exerted of the underside of the forepart of the lowermost board so that forepart of the said lowermost board is drawn into contact with the feed members 12.
  • reciprocation of the feed members 12 occasioned through the linkage end gearing aforesaid causes the feed members 12 initially to move forwardly and thereby feed the lower board of the stack 16 through the gap 17A between the bottom edges of the adjustable feed gates 17 and the bed 11 into the nip of the feed rolls 101, 102 which in turn progress the said board into the nip of the rotary creasing and/or cutting rolls 103, 104.
  • the suction exerted through the mouth of the auxiliary duct 25 causes the board in its progress to be drawn over the peripheries of the wheels 251 whereby the movement of the board into and through the nip of the feed rolls 101 and 102 is facilitated.
  • the degree of suction to be exerted in the auxiliary duct 25 is determined by adjustment of the plate valve 26.
  • the feeding operation then proceeds repetitively until the stack 16 is exhausted or the apparatus is stopped at the will of the operator.
  • feed apparatus in accordance with the invention is especially suited for use where the boards or blanks of sheet material are warped.
  • cardboard or sheet feeding apparatus in accordance with the invention is simple in construction and operation and more economical to install in cardboard or analogous sheet Working machinery than apparatus operating on the suction principle heretofore in use.
