- the chain shown schematically is guided over transport rollers 340a and 340b, also shown schematically.
- the chain in conjunction with the scale rollers, serves to adjust the transport unit 304 to certain formats of the sheets.
- the transport unit described is only shown schematically, and it is obvious that the number and the distance of the rolls depends on the sheets or sheet formats used (form height) and the number of sheets to be picked up. An example is shown in the figure in which the rollers are spaced 3 "(7.62 cm) apart.
- the transport unit 304 also includes, for safe takeover the fed double sheets from the inlet 302, two parallel guides 342 and 344, which are extend along the entire transport unit 304.
- section 300 is such that the Double sheets are fed through inlet 306, and once the first of the double sheets the first scale roll 334a reached, the double sheets are braked, and to Avoiding the leaves sliding on each other becomes too the time at which a leading edge of the first sheet the scale roller 334 ⁇ reaches one of the brake rollers 322a or 322b by actuating the corresponding actuator activated so with a rear edge of the second Leaf of the double leaves to engage so that a Sliding the sheets together is avoided. Subsequently the sheets are moved further by the transport unit 304, with additional double sheets fed simultaneously until a predetermined number of double sheets is contained in the transport unit 304. As soon as the predetermined number of sheets included in unit 304 these are sent to a subsequent transport unit in one cycle, which will be described later.
- the trap can, for example be omitted entirely, or double Brake rollers can, for example, by a single brake roller, which is subordinate to the trap.
- a brake roller can be used which have increased running resistance compared to conventional rollers has, so that by pressing them against a rear Edge on the second sheet a corresponding delay the same is achieved.
- FIG. 4A to 4C a first embodiment of the inventive method and a second Section of the paper handling machine schematically explained.
- the portion of the paper handling machine shown in Fig. 4 serves a predetermined number of sheets, which are arranged in a transport unit (not shown) are to spend in a simple way.
- Fig. 4A is schematically one in the paper running direction P last arranged transport roller 400 and an output roller 402 shown.
- the single ones Sheets 410 to 416 are arranged so that their in Paper running direction P front edges offset by the distance X are arranged.
- FIG. 4B shows the situation in which from the 4A illustrated sheet flow only a single sheet, namely the sheet 410 is to be output. This happens in that the transport unit moves the sheet stream caused by a predetermined distance so that only the leading edge of the first sheet 410 in contact with the Output roller 402 is brought. Through this clocked movement of the leaves and due to the continuous movement the output roller 402 is done by the as in FIG. 4B Arrow indicated the output of sheet 410 from the sheet stream.
- FIG. 4C shows the situation in which a group of leaves, namely leaves 412 and 414 from the leaf stream should be removed, in which case the Transport device a movement of the leaves or the Leaf flow causes the moving distance through the Number of sheets in the group and by the offset of the Leaves is determined. Through this clocked movement causes that now the first sheet 412 in the Sheet stream is brought to the output roller 402 and through this is removed, and subsequently the sheet 414 to the Output roller 402 is brought and is also removed.
- Section 500 is the one described schematically with reference to FIG. 4 Section in an embodiment according to an embodiment shown.
- Section 500 includes a second Transport unit 502 and an output unit 504.
- the second transport unit 502 comprises a pair of guides 506 and 508, which are from an entrance to the transport unit Extend 502 to an output 512 thereof.
- the transport unit 502 further comprises a conveyor belt 514, which is clocked by a motor not shown in FIG. 5 can be driven, and via two rollers 516a and 516b.
- the rollers 516a and 516b are in turn attached to a frame 518 as shown in FIG. 5 is shown schematically.
- transport rollers 520a to 520d are also provided, which cooperate with the conveyor belt 514, and by one predetermined distance from each other are.

- the roles are corresponding movable, so an attitude to different Enable formats.
- the transport unit described is only shown schematically and it is obvious that the number and spacing of the rolls of the sheets or sheet formats used (form height) and the number of sheets to be picked up. In the Figure shows an example where the reels are 3 " (7.62 cm) are spaced.
- first transport unit recorded Sheets inserted as soon as the first transport unit maximum possible or a predetermined number of sheets added Has.
- the individual are in the transport unit 502 Leaves are shingled and face each other one of their front edges in the direction of paper travel predetermined offset.
- the stop device enables stopping or provision a group of leaves.
- the following paper handling machine e.g. the collecting station, ready to receive, and the leaves were at the stop point provided
- Another example is one of the paper handling device downstream inserter accepted. While this is a group of sheets or single sheets located therein no more sheets are placed on the envelope Envelope issued. In this situation, the Stopper device already the one to be processed next Group or sheet to be processed next in the direction the output of the paper handling machine are moved and be provided at the stopper so that when the inserter to record the next group or the next Sheet is ready, the distance to be bridged is shorter than with a feed from the second transport unit, so that the feed is faster.
- the stopper device opens, alternatively or additionally to the first-mentioned functionality described above the stopper device, the possibility of a group to "buffer" (store) while the shingled stream in the example shown in Fig. 6A from the first Transfer the transport unit to the second transport unit becomes.
- the slightly longer intermediate bar, which is used for Handover may be required, not a degradation.
- a pair of sensor rollers 534a and 534b is arranged by means of that between the two rollers 534a and 534b Leaves are counted. The count is done such that a corresponding through the passing leaves Spacing of the two rollers 534a and 534b will, in turn, shift the signaling lever 536 for an inductive measuring element 538 causes a change in inductance sets based on the the number of between roles 534a and 534b continuous sheets can be detected.
- the sensor can also are arranged in front of the output 512.
- the output rollers 540a and 540b which over in Fig. 5 motors not shown continuously with a predetermined speed are driven in the range from 2 m / s to 5 m / s, preferably 4.75 m / s.
- the rollers 534 and 540 are on the frame 532 of the section 504 attached.
- the exit rollers 540a, 540b and the last one Transport rollers 520d are spaced a distance which ensures that an engagement of the sheet by the Exit rolls occur when the shingled stream is moved.
- the distance between the rollers is smaller than the smallest possible Form height (format length or length of a sheet in Direction of paper measured). With a format length of 3.5 " (8.89 cm) the distance is 3 '' (7.62 cm) so that the sheet when moving on from the following role safely is taken.
- section 500 it is first determined how many of the sheets contained in the transport unit 502 to a subsequent processing device during a cycle are to be issued. Depending on the number of output Leaves are determined by what distance the in arranged in the direction of the transport unit 502 the output unit is to be moved, and this movement is then performed with the output rolls 540a and 540b the front one in the paper running direction Subtract sheet of the stream of scale, in the event that for example, only a single leaf from the stream of flakes a corresponding movement is to be removed the scale flow by means of the transport unit 502 in such a way that only the foremost sheet leaves the exit rollers 540a and 540b is provided so that during this clock only this single sheet is output. Should be several Leaves, e.g.
- the shingled stream moves for a period that is slightly larger than the cycle time required to output a single sheet, however, is significantly lower than for two separate issues Leaves so that in this case the one after the other Sheets of the subsequent processing unit arriving at the output rolls are fed.
- This will within provided a group at a time that was significantly shorter is as the amount of time that is conventionally required is, for example, three individual sheets for a group to feed a subsequent processing unit.
- the entire paper handling machine is 600 shown, and as can be seen, this exposes itself section 300 and section 500 together, the Section 500 to section 300 in the paper running direction P follows.
- the paper handling machine are others, however Configurations possible.
- 6B is another embodiment of the paper handling machine 602 shown, in which the transport units 304 and 502 are arranged parallel to one another, between the inlet unit 302 and the output unit 504.
- a deflection device 604 is between the inlet unit 302 and the two transport units 304 and 502, which is effective to first double sheets one of the two Feed transport equipment. Once the predetermined or the maximum possible number of sheets in one of the transport devices is added, the deflection device is on the other of the two transport units switched, and the Double sheets are in continuous form the further Transport unit fed. At the same time, the operation the first transport unit from continuously to clocked switched, and the predetermined number of sheets in groups in the manner described above and clocked via the device 606 to the output unit 504 forwarded.
- FIG. 7A shows the two transport units 304 and 502, taking the appropriate setting of the formats by increasing and reducing the number accordingly reached by scale rollers 334 or transport rollers 520 becomes. Depending on the format, more or fewer roles used.
- FIG. 7B shows the transport units 304 and 502, the conveyor belts in this case by so-called Vacuum belts are realized.
- 7C is one further embodiment shown, in which the transport units 304 and 502 are made in one piece.
- Fig. 7D is another embodiment of the format setting shown.
- the 2-up printed sheets are placed on top of each other, with a slight longitudinal offset, so that these leaves are pre-scaled and later easy to separate. If larger groups are formed, the others, pre-scaled leaves formed a larger scale stream.
- the paper handling machine described above enables the continuous intake of merged leaves and thus a high increase in performance, because even with group separation within the merged leaves these from the forerunner can be spent together. So there is only one bar required. This enables the use of continuously current forerunners, e.g. Rotary cutting machine etc., which means a further increase in performance.
- is according to one embodiment of the present invention is a paper handling machine formed, essentially from a feed transport with brake, a trap, a shed transport, and there is an output transport as in the previous one have been described with reference to the figures.
- the feed transport device with brake serves to slip avoid damage to the incoming sheets, and, as has already been described, the shed transports can be arranged in two levels, and are from each other can be operated independently.
- a cutting machine When operating the paper handling systems described above is first in a cutting machine (Fig. 1) cut a paper web lengthways and crossways. The cut like that Leaves are placed side by side in pairs the merger (Fig. 1) hand over the leaves with a slight longitudinal offset on top of each other.
- the (merged) merged by the forerunner Leaves are offset with a small length of about 20 mm from the feed handling 302 of the paper handling machine.
- the leading edge of the leading sheet turns on the scale roller 334a braked, the lagging sheet becomes braked at the rear edge. This avoids that the sheets are pushed over each other again.
- Further "Double leaves” become, depending on the position of the trap 314, scaled ascending or descending, continuously transported into the transport unit 304 of the buffer, until the route is completely filled.
- the transport units or the buffers one after the other arranged are the transport units or the buffers one after the other arranged, the newly formed scale flow in the first Transport unit 302 after reaching a predetermined Number of sheets and if the second transport unit is emptied completely in one intermediate cycle the first transport unit to the second transport unit is handed over.
- the switching device 604 activated so that while the leaves now in the second level in the manner described above and Run in, the first level is emptied clocked.
- the advantages of the present invention are that very high sheet outputs can be achieved because it is continuous Sheets can be picked up without Change of group should be respected. Another advantage is that the forerunners and followers can be operated independently, i.e., the The cutting machine and the collecting station brake, for example not mutually exclusive. By scaling the Leaves become a slight separation or group formation allows.
