Description

  The present invention relates to an underlay takeout device in a paper feeder that continuously supplies a thick paperboard such as a cardboard sheet to a sheet processing machine such as a printing machine.

  In general, many cardboard sheets manufactured by a corrugator are stacked with the front liner facing down. The stacked corrugated cardboard sheets (hereinafter referred to as stacked sheets) are then set in a paper feeder and are continuously supplied by the paper feeder to a hopper of a sheet processing machine such as a printing machine.

  As the paper feeder, a sheet feeding device and a kicker movable in the sheet conveying direction by the sheet feeding device are supported by a tilting table swingable about a horizontal axis, and the tilting table is substantially vertical. With the kicker positioned at the lower end of the sheet feeding device, the stacked sheets are fed onto the kicker, and the stacked sheets are laid sideways supported by the sheet feeding device and the kicker by swinging the tilting table. After that, it has been conventionally known that the stacked sheets are continuously fed onto the carry-in end portion of the sheet feeding conveyor device arranged on the downstream side of the sheet feeding device by driving the sheet feeding device and moving the kicker. ing.

  In the paper feeder, as described in Patent Document 1, stacked sheets that are laid down by tilting of the tilting table are continuously sent out in a lapped state where the sheets overlap each other, and in Patent Document 2 As described above, there is a sheet in which a horizontally stacked sheet is sequentially sent out in a state of being divided into several sheets from the top sheet.

  In any of the above-described paper feeders, the stacked sheets fed onto the kicker are supported by an underlay such as a plywood board, and are fed onto the kicker together with the underlay, so that all the stacked sheets are sent out from the carry-out end of the sheet feeding device. In the state, an underlay is left on the kicker.

  For this reason, after feeding out the stacked sheets, it is necessary to remove the underlay remaining on the kicker and then feed the next stacked sheet onto the kicker.
