Abstract
A sheet receiving and stacking apparatus is formed of a base table with a stacking section for stacking a rectangular sheet, and a guide device for receiving the rectangular sheet and for guiding the rectangular sheet to the stacking section of the base table. The guide device has a rotatable curved guide surface, and guides the rectangular sheet to the stacking section while being rotated with the side edges of the rectangular sheet when the guide surface has received the side edges of the rectangular sheet which is floating downwardly.
Claims12
A sheet receiving and stacking apparatus for a rectangular sheet with two side edges parallel to each other, comprising:
- a base table having two side portions and a stacking section situated between the two side portions, said stacking section receiving the rectangular sheet thereon, and
- a plurality of guide means attached to the respective side portions of the base table to be parallel to the side edges of said rectangular sheet to be fed, said guide means guiding said side edges of the rectangular sheet introduced above the stacking section to locate the rectangular sheet onto said stacking section of said base table, each of said guide means having a rotatable member, said rotatable members guiding said sheet to said stacking section while rotating with the side edges of said sheet when said rotatable members contact the side edges of said rectangular sheet which floats downwardly.
A sheet receiving and stacking apparatus as claimed in 3, wherein said rotatable member of said at least one guide means is spherical, and said support member comprises a shaft mounted through the center of said rotatable member, arms secured on both ends of said shaft, and a support shaft for rockably supporting said arms.
A sheet receiving and stacking apparatus for a rectangular sheet with two side edges parallel to each other, comprising:
- a base table having two side portions and a stacking section situated between the two side portions, said stacking section receiving the rectangular sheet thereon, and
- two guide means attached to the respective side portions of the base table, each guide means having a side plate attached to the base table, a window situated in the side plate, an elastic connecting member fixed to the side plate, and a guide member connected to the connecting member and located in the window, a part of said guide member being situated above the stacking section so that when the rectangular sheet is introduced above the stacking section and falls downwardly, the side edges of the sheet contact the parts of the guide members and push the guide members outwardly through the elastic connecting members to thereby float downwardly on the stacking section.
