Transport with media hold down for inkjet printers
09636930 · 2017-05-02 · ·

A transport with media hold down is used with an inkjet printer. A plurality of spar links and vacuum links are connected pivotally together to form an endless belt orbiting around drive wheels and driven wheels. Vacuum links have hollow chambers to hold the media sheet against the endless belt using vacuum. At least one spar is received in a slot on a spar link. The spar extends above the link to receive the media sheet. The spar moves into a clamping position by a cam and follower to clamp the media sheet against the spar link. The media sheet will thus pass beneath the inkjet print head without contact. The spar moves into an extended position by the cam and follower to release the media sheet. The spar moves into a retracted position below the spar link surface by the cam and follower to allow the media sheet to exit the transport.

APPARATUS AND METHOD FOR FORMING A STACK OF ADVERTISING MATERIAL COMPILATIONS
20170008720 · 2017-01-12 · ·

An apparatus and method for forming a stack with advertising material compilations respectively consisting of an envelope with inserts therein, and having a common, leading folded edge. The apparatus includes a feed conveyor, a transfer conveyor and a stacking device. The transfer conveyor comprises a central wheel that rotates around a first rotational axis, a carrier wheel that rotates around a second rotational axis oriented parallel to the first rotational axis, and a number of pivoting arms with respectively one gripper. The second rotational axis is arranged below a horizontal plane extending through the first rotational axis. The grippers are respectively positioned on the pivoting arm to rotate around an axis. The grippers take over the advertising material compilations in a takeover region from the feed conveyor, transfer the adverting compilations in a transfer region to the stacking device which extends into the transfer region and deposit these on the stacking device.

SHEET TAKEOUT METHOD

A sheet takeout method includes: pressing, when a restraint device is in a restrained state, a transfer plate which is in a horizontal state to pickup and hold a topmost sheet member; pressing the sheet members by an inelastic deformation part of the transfer plate while setting the restraint device to be in a non-restrained state and setting the transfer plate to be in an elastically deformed state; inserting a restraining blade into a space formed between the topmost sheet member and its underlying sheet member and setting the restraint device to be in the restrained state again; returning the transfer plate that has picked up and held the topmost sheet member to a horizontal state while retracting the transfer place upward; and transferring the topmost sheet member picked up and held by the transfer plate to a receiving holder.
