The present invention relates to a paper feed ream feeder.

  Paper made by a paper machine is completed in a wound state, and is cut into a flat sheet having an appropriate size depending on the application before shipment. This flat sheet is packed with a wrapping paper in a predetermined number of wrapping sheets, and a label is attached to the wrapping paper before shipment. Processing into a flat sheet is performed by cutting the wound paper into a predetermined size while rewinding the web, and a predetermined number of the cut flat sheets are stacked and counted for each number of wrapping sheets. An index sheet is inserted. The stack in which the index sheets are inserted is supplied to a packaging device for packaging every number of packages.

  When supplying to the packaging device, the number of reams (feeding reams) to be provided for the packaging divided by the index sheet is separated from the ream pile, which is a stack of flat sheets, This is done by separating them with an index sheet. In this case, the term “ream” refers to a unit of paper or paperboard, and refers to a laminate of a suitable number of flat sheets, and the ream provided to the packaging device is referred to as a paper feed ream. Patent Document 1 discloses a method and apparatus for automatically separating and transporting a predetermined number of ream bodies from a pile of paper, as this type of paper feed reel feeding device for separating and transporting a paper feed reel to a packaging device. There is. This paper ream feeding device is a so-called robot that separates and feeds, but there are various difficulties in automation and it has not yet been put into practical use. This is what is being done.
