Definitions

  • the present invention relates to a paper feeding apparatus in a box making machine for making boxes of paper boards such as corrugated cardboard sheets or the like.
  • FIG. 3 A general construction of a heretofore known paper board feeding apparatus 1 is shown in Fig. 3.
  • paper boards 5 are stacked in a hopper formed of a table 2 and a front stopper 3 and a rear sup­port 4 on the table 2.
  • a slide bar 6 that is slidably buried in the table 2 is adapted to be reciprocated by a crank mechanism 7.
  • a kicker 8 is fixedly secured to the slide bar 6, so that as a result of operation of the above-­mentioned crank mechanism 7, a paper board 5 positioned at the lowermost level in the hopper is kicked out one by one through a gap clearance at the bottom of the front stopper 3 of the hopper in the direction of an arrow.
  • a paper board 5 de­livered from the hopper is pinched by the upper and lower rolls 9 and 10 and continuously sent to the subsequent processing station by rotation of the both rolls 9 and 10.
  • the gap clearance at the bottom of the front stopper 3 is preset by a gap adjusting device provided separately, though not shown, so that it may become somewhat larger than the thickness of the paper board 5.
  • a gap adjusting device provided separately, though not shown, so that it may become somewhat larger than the thickness of the paper board 5.
  • the height from the upper surface of the table 2 of the front edge of the paper board 5 would differ, and so, it is necessary to adjust this gap clearance each time.
  • a paper board feeding apparatus of the type that a paper board at the lowermost level in a hopper is delivered one by one through a gap clearance at the bottom of a front stopper of the hopper, in which press means for reforming deformation of paper boards is disposed above a stack of the paper boards.
  • a paper board feed­ing apparatus of the type that paper boards are stacked in a hopper and the paper boards are delivered one by one from the bottom of the hopper to the subsequent processing station, which apparatus comprises conveyor means for conveying and feeding paper boards into the hopper and press means for pressing the paper boards conveyed into the hopper by the conveyor means within the hopper to stack them so as to maintain a constant height and thereby reforming warp of the paper boards.
  • the paper board feeding apparatus Since the paper board feeding apparatus according to the present invention has the above-featured construc­tion, the paper boards are subjected to reforming forces and the height of the stack of paper boards can be kept constant within the hopper by the action of the press means, and nearly in synchronism with the paper board at the lowermost level within the hopper being ejected one by one, an additional paper board is fed to the top of the hopper by the conveyor means. While the paper board at the lowermost level in the hopper is kept flat as pressed by the press means, the lowermost paper board could be delivered to the subsequent processing station by driving a kicker provided above a crank mechanism.
  • the paper board feeding apparatus upon delivering paper boards from the hopper, they can be reliably delivered one by one, hence stoppage of a paper making machine or troubles in the subsequent processing station would never occur, and so, a lot of advantages such as enhancement of a produc­tivity and prevention of loss of resources can be brought about.
  • paper board 5 are stacked within a hopper 22 which is formed of a table 2 and a front stopper 3 and a rear support 4 provided on the table 2, and a paper board 5 at the lowermost level of the stack is adapted to be kicked out by reciprocating motion of a kicker 8 projected from the upper surface of the table 2.
  • This paper board 5 kicked out by the kicker 8 is pinched between a pair of upper and lower rolls 9 and 10 disposed in the subsequent location in the paper board feeding apparatus, and it is positively pulled out and delivered.
  • the above-mentioned kicker 8 is fixedly secured to a slide bar 6 which is adapted to slide within the table 2, and so, the kicker 8 would reciprocate jointly with the slide bar 6.
  • the slide bar 6 is made to reciprocate by a crank mechanism 7 under the slide bar.
  • the above-described portion of the appa­ratus is similar to the paper board feeding apparatus in the prior art shown in Fig. 3.
  • reference numeral 11 designates a pressing device which forms a principal part of a paper board feeding apparatus according to the present invention
  • reference numeral 12 designates a roller
  • numeral 13 designates a pivot axle
  • numeral 14 designates an arm
  • numeral 15 designates a spring (although a spring is shown in the illustrated embodiment, any resilient body such as an air cylinder could be employed in place of the spring, or else the roller itself could be made of elastic material.)
  • numeral 16 designates a fulcrum pin.
  • a paper board feeder 20 comprising a feed roller 17 having a separate driving device for feeding paper boards to the top of a hopper 22, a nip-in roller 18, a guide 19 and the like.
  • any resilient means such as, for example, a leaf spring 21 is used for pressing a stack of paper boards as illu­strated in the second preferred embodiment shown in Fig. 2.
  • the remaining portion of the second embodiment is similar to the first preferred embodiment, and so, further de­scription thereof will be omitted.
  • the paper boards 5 stacked within the hopper 22 are kicked out one by one from the paper board at the lowermost level by means of the kicker 8, and they are reliably delivered to the sub­sequent processing station through a gap clearance (H) between the bottom of the front stopper 3 and the top surface of the table 2.
  • the distance between the front stopper 3 and the rear support 4 can be set always at an optimum condition (normally at l + 3 mm) with respect to a length (l) of the paper board 5.
  • the bottom position of the front stopper 3 can be set at a fixed height (H).
  • nip-in roller 18 is of non-driven type in the above-described embodiment, modification could be made thereto so as to be driven by the existing driving system.
  • the present invention when the paper boards are delivered from the interior of the hopper, they can be reliably de­livered one by one, hence stoppage of a machine or troubles in the subsequent processing station would be eliminated, and therefore, the present invention brings about a lot of advantages such as improvements in a productivity and prevention of loss of resources.
