  "title": "Board piling apparatus",
  "abstract": "This invention relates to a board piling apparatus whereby the boards such as for example corrugated cardboards delivered individually or in small bundles in a flatly laid state are raised up and collected and the collected boards are then turned about 90° and stacked up in the form of a pile. This apparatus is particularly featured by incorporation of a board raising up device adapted for raising up the board which are fed in a flatly laid state.",
  "claims": [
    "1. A board piling apparatus whereby the board delivered individually or in small bundles in a flatly laid-down state are raised up and collected in a lot and the collected boards are then turned about 90° to form a pile of boards, characterized by incorporation of a board raising-up device comprisng a conveyor by which said boards delivered in a flatly laid-down state are received in the form as they are, a first lever pivotally supported at a position lower than the carriage surface of said conveyor, means for turning said first lever so that the first lever rises up above the carriage surface of said conveyor to lift up the leading end of the board and raise up the board on said conveyor and thereafter said first lever falls down below the carriage surface of said conveyor, a second lever pivotally supported at a position lower than the carriage surface of said conveyor, means for turning said second lever so that the second lever rises up above the carriage surface of said conveyor to lift up the trailing end of the board and raise up the board on said conveyor and thereafter said second lever falls down below the carriage surface of said conveyor, a board holding lever pivotally supported at a position below the carriage surface of said conveyor and slightly closer to the delivery end of said conveyor than the pivotted point of said second lever, and means for turning said board holding lever so that the board holding lever rises up above the carriage surface of said conveyor so as to hold the lower end of the board raised up by said second lever and thereafter said board holding lever falls down below the carriage surface of said conveyor.",
    "2. A board piling apparatus according to claim 1, wherein said first lever consists of a first bar portion extending in the direction of the delivery end of said conveyor from the feed end of said conveyor and a second bar portion extending upwardly from the end of the said first bar portion substantially vertically thereto and carrying a freely rotatable roll at its end, and said second lever carries a freely rotatable roll at its end.",
    "3. A board piling apparatus according to claim 1, wherein the means for turning said first lever, said second lever and said board holding lever are pistoncylinder devices."

  "description_excerpt": "This invention relates to a board piling or stacking up apparatus whereby the boards such as for example corrugated cardboards delivered individually or in small bundles in a flatly laid state are raised up and collected and the collected boards are turned about 90° and stacked up in a pile, said apparatus featuring particularly incorporation of a board raising up device adapted for raising up the boards which are fed in a flatly laid state.\n\nIn most of the conventional board piling apparatus of this type, the board delivered individually or in small bundles in a flatly laid state are received onto a suitable conveyor and raised up on said conveyor by workers, and the raised up boards are then placed on a transport conveyor and propped up by one of the board supports on said transport conveyor. Each of said board supports is connected to an endless carrier member in the transport conveyor so as to be movable with said member. This board support is arranged to move slightly forwardly upon placing of the boards on the transport conveyor, and when a predetermined number of boards are placed on the transport conveyor, this lot of boards is carried to the delivery end of the conveyor and turned about 90° thereat by a turn-over means to form a pile of boards. This pile of boards is either transferred onto a discharge conveyor directly from said turnover means or pushed out from said turnover means by a pusher provided in said means.",
