A separating apparatus, in which the sheet material is conveyed in stacks via a stack transporting system to the stack holder, comprises first apparatus for effecting selective mechanical manipulation of the stack going through the separation process in case sensors, which check the separation sequence, detect a deviation from the proper separation process. Further sensors may be provided in addition for testing the stack before and during separation as to its shape and/or state of conservation. Taking this information into account, an irregularity occurring during separation can then be combatted by triggering that measure which appears best suitable for automatically eliminating the disturbance of the separation process.

Apparatus and a method for separating sheet material

A separating apparatus for sheet material in which the sheet material is conveyed in stacks via a stack transporting system to a stack holder including a stack manipulator for effecting selective mechanical manipulation of the stack going through the separation process in the event that a deviation from the proper separation process is detected. In addition, a stack tester may be provided for testing the geometric and physical condition of the stack of sheet material before and during separation. An irregularity occurring during separation can be combatted by instituting a stack manipulation procedure which appears best suitable for automatically eliminating the disturbance of the separation process.

In a sorter for data carriers, in which the data carriers, for testing, run past an arrangement of sensors located on both sides of the transport path, at least the sensors on one side of the transport path are arranged on a separate mounting plate. This mounting plate is pivoted so that the sensors located opposite each other can be moved apart, thus exposing the transport path.

Apparatus for testing data carriers

A device for removing a band (2) wrapped around a bundle (1) of sheets by means of a cutting device (11). The cutter (7) of the cutting device is arranged on the plane on which the bundle is transported in such a way that it dips into a side face of the bundle, cutting along the entire length of the bundle and thereby severing the band located at right angles to the side face. The severed band (2) is grasped on the side opposite the cutting by a hook (13) of a pull-off device (12) provided opposite the cutting device (11), and removed at right angles to the direction in which the bundle (1) is transported.

Device for removing a band from a sheet bundle

A stacking device for sheet material such as banknotes and receipts has a stacker drum with a suction opening at a predetermined location on the periphery. The suction opening grips the leading edges of the sheets to be stacked at a first tangential position and releases the sheets against a stopper at a second tangential position. The stacker drum has air openings on the periphery behind the suction opening. The air openings discharge pulsating compressed air to separate the portion of the sheets trailing the leading edges from the drum.

Stacking device for sheet material

An apparatus for transporting sheet material such as bank notes, comprising separate endless conveyor belt systems which are conducted about guide or deflection rollers of varying diameter and which extend parallel adjacent to the conveyance path. The individual sheets are held between the belts of the two systems by friction. In order to avoid different-size reversals when rollers with varying diameters rotate, the angle of contact of the conveyor belts is selected in response to the diameter of the rollers such that the reversal remains constant over the whole of the length. In the case of a finitely thick belt the word reversal means the velocity of the inner fibre running on the rollers in relation to the neutral fibre in %.

Apparatus for transporting sheet material

An apparatus for separating a strap from a packet of thin sheets, such as bank notes, bound by the strap includes a housing, a magazine disposed within the housing having a receptacle and a drawer-like member received in the receptacle. A plurality of the packets are disposed in the drawer-like member which can be moved by a mechanism in the housing so that a portion of the drawer having a packet is exposed to an ejector member in the housing. The ejector member is operative to eject the exposed packet. Means are provided for engaging the strap and stack of the exposed packet. The means are operated to separate the stack and the strap.

Portable input magazine

A feeder device for transferring a stack of paper sheets, such as bank notes, from a stack feeder device to a sheet receiving device includes an air conducting plate mounted between the stack feeder device and the receiving device. The plate has a plurality of bores extending therethrough at spaced intervals. Fluid pressure means are connected to the bores for discharging a stream of pressurized fluid along a feed path in the direction of the sheet receiving device and producing a low pressure along a surface of the plate adjacent the feed path. The bores are oriented to diverge toward opposite sides of the feed path.

Device for separating record carrying items

A stacker for sheet material has a stacker drum. The stacker drum receives sheets from a transport system at a first tangential position and arcuately moves them to a stop at a second tangential position against which the stack is formed. The stacker drum has a row of suction openings for gripping the leading edge of the sheets followed by compressed air openings. The compressed air openings are positioned behind the suction openings sufficiently far so that the compressed air is applied to the sheets only after the leading edges have been run up against the stop.

Stacker for flat material

A separating unit for flat sheet material has a rotating separating drum with suction openings on its outer face. The material to be separated is run tangentially between the separating drum and a suction drum. The separating drum has suction holes ahead of the suction openings that initiate the evacuation of air between the sheet and drum by a pulling effect lower than that of the suction openings.

Separating unit for flat sheet material

A stacker apparatus for flat sheet material has a suction drum rotating on a stator. The suction drum grips the flat sheet material at one tangential position, arcuately moves it, and releases it on a stack at a second tangential position. The suction drum has a section containing a plurality of suction openings for gripping the sheet material. A plurality of peripheral suction channels on the stator communicate with the suction openings. The width of the suction channels decreases step-wise along their length so that the suction openings are initially in full communication with the channels, thereafter the suction openings are partially closed, and finally, selected ones of the suction openings are completely closed as the drum rotates.

Flat material sheets are separated by a separating drum rotating on a supporting plate that pulls the sheets separately one after another off a pile and directs the separated sheets toward a subsequent transporting system. The separating drum comprises a stator with sectorial suction channels extending circumferentially and a rotor with suction openings communicating with the suction channels. The communication between the suction openings and suction channels is made in such a way that the sheet material adjacent to the edge running on the supporting plate is attached to the drum by the action of the vacuum earlier than in other areas. This area may be released later than the other areas.

Process and apparatus for separating flat sheet material

A stacker for flat material sheets unfolds dog-eared sheets to facilitate stacking. The rotating stacker drum has a cut out preceding the sheet adhering suction openings with an unfolding face and a run-in face.

Stacker for flat sheet material such as banknotes, bank papers, receipts

A method and apparatus for automatically sorting packets of thin sheet articles such as securities, bank notes and the like which are bound in a stack by a band. A series of modular units are provided in which the band and the stack are mechanically separated, each sheet of the stack is conveyed independent of the band, each sheet is tested and directed to a target location dependent upon the results of the test. The transport of sheets having predetermined characteristics is coordinated with the transport of the band.

Method of automatically sorting thin sheet articles

The apparatus comprises a roll, having an elastic surface, mounted for rotation about a fixed axis with the elastic surface arranged to engage one surface of a record carrier. A piezoelectric transducer is mounted perpendicular to the axis of the roll and rigidly with respect to the roll, and a sensor is mounted quasi-rigidly, with respect to the transducer, between the roll and the transducer, the sensor being fixedly joined to the transducer. In the quiescent condition, without a record carrier being passed between the sensor and the roll, the distance from the roll surface to the sensor is smaller than the smallest paper thickness to be measured. The transducer is mounted in a holder having a spring member fixedly joining the sensor to the transducer. The sensor may include a sensing roll or may be designed as a sensing runner with a sharp edge, and an elastic damping plate connects the transducer to the sensor.
