摘要:
A device for treating substrates has a separation system, with which processed substrates can be separated into one or more waste parts and at least one blank. The device for treating substrates offers improved flexibility. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder is able to secure replaceable packing, along with first and second openings which, when the packing is secured, are covered at least partially by perforations that may be formed in the packing. A first air supply supplies air to the first openings and a second air supply supplies air to the second openings independently of the supply of the air to the first openings. The first and the second air supply are switchable between a suction air supply and a blower air supply.

The present invention provides a vacuum suction adjustable transfer roller and a film attachment method using the transfer roller. The transfer roller includes: a roller body (20) and a plurality of adjustment devices (40) mounted in the roller body (20). The roller body (20) includes a plurality of air draw-in passages (22) uniformly distributed therein. The air draw-in passages (22) draw in air by means of an air evacuation device. Each of the adjustment devices (40) includes: a valve (42) arranged in each of the air draw-in passages (22), a piezoelectric ceramic piece (44) connected to the valve (42), and a control circuit (46) electrically connected to the piezoelectric ceramic piece (44). The control circuit (46) controls the intensity of an electric field applied to the piezoelectric ceramic piece (44) so that the piezoelectric ceramic piece (44) undergoes deformation under the action of the electric field and the valve (42) is caused by the deformation of the piezoelectric ceramic piece (44) to selectively insert into or withdraw out of the air draw-in passages (22) so as to control flow of air drawn in by the air draw-in passages (22) and thus controlling the magnitude of a vacuum suction force induced by the air draw-in passages (22).

A single sheet handling device (14a to 14d, 30, 200, 252, 270, 350) for the input and the output of rectangular single sheets (38) respectively into and out of a container (12a to 12d). These rectangular single sheets can in particular be banknotes (38). The single sheet handling device (14a to 14d, 30, 200, 252, 270, 350) has a feeding device with feeding elements for the sheet-by-sheet feeding of single sheets (38) and for storing these single sheets (38) in a stack (36) of single sheets in the container (12a to 12d). Further, the single sheet handling device has a separating device with separating elements for the sheet-by-sheet removal of single sheets (38) of the stack (36) from the container (12a to 12d). The feeding elements and the separating elements are arranged separately from the container (12a to 12d).
摘要:
A method for operating a sheet handling system including the steps of: determining a location of a next collation mark on select sheets of the stack of material, selecting an operating mode based upon the proximity of the next collation mark relative to a leading or trailing edge of each of the select sheets, processing the singulated sheets in a first operating mode when the next collation mark is proximal to the leading edge of each of the select sheets, and in a second operating mode, when the next collation mark is proximal to a trailing edge of each of the select sheets. Each of the select sheets is buffered to change the spatial relationship between each of the select sheet and each completed collation of sheets along the feed path. By selectively processing the sheets based upon the location of the next collation mark, the conveyance feed path is minimized.

According to one embodiment, a separation and extraction apparatus includes an extraction unit, separation unit, air supply mechanism, detector, and controller. The extraction unit extracts and conveys one or more paper sheets from a stack of paper sheets. The separation unit separates one paper sheet from the other paper sheet(s) of the one or more paper sheets. The air supply mechanism supplies air toward a side surface of the stack. The detector detects a bundle state of the stack, which is related to a contact state between the paper sheets. The controller sets an extraction condition depending on the bundle state, which includes drive conditions for the extraction unit, separation unit, and air supply mechanism.

A sheet handling apparatus is provided that includes a take-out member to take out a sheet from a take-out position by rotating the sheet in a state in which negative pressure is applied to the sheet and the sheet is adsorbed to the take-out member. A conveyor portion receives and conveys the taken out sheet by the take-out member and a control portion controls the take-out member such that, when the sheet at the take-out position is being adsorbed to the take-out member, the take-out member is rotated at a circumferential speed that is slower than a conveying speed of the sheet at the conveyor portion. In addition, when the sheet adsorbed to the take-out member is being transferred to the conveyor portion, the take-out member is rotated at a circumferential speed that is the same as a conveying speed of the conveyor portion at that time.

A paper feeding apparatus capable of preventing noises generated when picking up and transferring paper, and an image forming apparatus having the same. The paper feeding apparatus according to the present invention comprises a pickup unit, which is disposed upstream of a paper cassette relative to the direction in which the uppermost sheet of paper loaded in the paper cassette moves, to pick up the uppermost sheet of paper, and a lifting unit which lifts the sheet of paper vertically to reduce friction between the paper and the paper beneath it when the pickup unit picks up the sheets of paper.

The invention relates to a pneumatic feed and separation system (1) for flat substrates (3) such as papers and the like in a stack (5, 5′, 5″), and to a corresponding method. The system has: a rear edge separating apparatus (10) for separation of a top substrate (3) from the stack (5, 5′, 5″) in the area of the rear edge (9) of the stack (5, 5′, 5″) in the transport direction (7), a transport apparatus (20) for the top substrate (3) in the area of the front edge (8) of the stack (5, 5′, 5″) in the transport direction (7), and a control unit (30). In order to ensure automatic adjustment of the system, in particular automatically optimized operation of the system, the invention provides that the rear edge apparatus (10) and/or the transport apparatus (20) comprise/comprises an automatically controllable pneumatic system—in particular with a compressed-air-based separating unit and a suction-air-based separating unit, in particular an automatically controllable separating mechanism with a restraint function for substrates below the top substrate (3), in particular a suction-air-based transport unit—and an automatically controllable motor system. The control unit (30) is designed for automatic presetting of substrate-dependent parameter information—in particular at least for the compressed-air-based separating unit, for the suction-air-based separating unit, for the separating mechanism, for the separating motor system and for the transport unit—and the associated pneumatic system and/or motor system are/is designed for automatic adjustment thereof on the basis of the parameter information.
