Definitions
- the present invention relates to a method and an apparatus for forming sheet groups from a plurality of sheets, in particular to a method and an apparatus for forming sheet groups from a plurality of paper sheets which collect the individual sheet groups using a paper merging device ,
- Paper handling devices or collecting systems which work with a merger, that is to say a paper merging device, are already known in the prior art.
- a merger is e.g. arranged in front of or after a cutting machine and works in such a way that sheets arranged next to one another in the sheet running direction, for example two printed sheets, are provided, and the merger overlays the adjacent papers or sheets and then outputs them to a directly connected collecting station, in which the Leaves are collected so as to form the individual leaf groups.
- FIG. 11A Such a known paper handling device 900 is shown in FIG. 11A, which comprises a paper feed device 902, a paper transfer device 904 (merger), a collecting station 906 and a folder 908.
- the paper or The direction of sheet travel that is to say the direction in which the individual sheets pass through the device 900, is represented by the arrow P.
- the sheet feeder 902 a paper web 910 is fed, which is printed in a printer (not shown) according to predetermined data.
- the unit 902 further comprises a cutting unit (not shown) which cuts the paper web 910 after it has been printed in such a way that two individual sheets 912 and 914 are formed from the paper web 910, as is shown schematically in FIG. 11A.
- the separated sheets 912 and 914 are passed on by the unit 902 to the merger 904, which merges them from the adjacent arrangement into a common path.
- Sheets 912 and 914 are transferred from merger 904 to collection station 906, where the received sheets are collected into a stack 916. If the desired number of sheets or the desired group of sheets is stored in the collecting station 906, the stack 916 formed is passed on to the folding device 908, in which the corresponding folding of the stack of sheets takes place. The stack is then fed to further paper processing, for example inserting it into an envelope or the like.
- control is also shown schematically at 918, which is connected to the individual modules 902 to 908 and effects the corresponding control of the overall device 900.
- odd sheet group means that in the example shown in Fig. 11, the respective sheets belonging to a single sheet group are staggered in the paper web 910, that is, two sheets are provided while the paper web 910 is being cut , but they belong to different leaf groups for the example considered.
- FIG. 11B shows the initial situation in which a preceding sheet group X in the collecting station 906 was collected.
- the merger 904 which can be operated in such a way that the adjacent sheets can be individually driven, there is still a sheet from the sheets created in the previous step, which belongs to group A. , and which is designated as sheet A.
- the sheet feeder 902 the not yet completely cut sheets A 'and B, which belong to group A and group B, are at the exit.
- FIG. 12 a flow diagram for the system 900 is shown, which represents the output times of the individual components of the device 900, namely for oddly arranged two-sheet Groups.
- the time in milliseconds is plotted on the x-axis, and the corresponding output times of the individual components, namely the collecting station 906, the merger 904 and the sheet feeder 902 are plotted in the direction of the y-axis, the individual output times also being plotted are assigned to the respective sheets or sheet groups in order to clarify which sheets are currently being processed by which of the individual components.
- the already completed stack X is started to be moved out of the collecting station 906, the period of time starting at Extending this stack is 150ms. Simultaneously with the start of the extension of the stack X from the collecting station 906, the sheet A still lying against the merger 904 is started to be moved through, which, as can be seen from FIG. 12 (see at 904 L), takes 200 ms. Also at the same time as the stack X is moved out of the collecting station 906, the sheet feed device 902 is put into operation in order to cut the paper web already printed there into the single sheets A 'and B, which takes 200 ms.
- FIG. 11C shows phase 2, a situation as it appears after 150 ms based on the situation in FIG. 11B.
- sheet A is at this point on the way from the merger's entrance to collection station 906, and sheets A 'and B are almost completely cut by sheet feeder 902.
- the stack X is now already in the folding unit 908, where a corresponding folding is carried out.
- the further processing of the stack X is of subordinate interest in the present case, with conventionally further handling of the folded stack, such as insertion into an envelope or the like, for example.
- the sheet A is forwarded in the merger 904 and the sheets A 'and B are cut in the sheet feed device 902 at the same time as the start of the stack X, which, as also mentioned, takes 200 ms.
- the situation that arises after this time lapse is shown as phase 3 in FIG. HD, and as can be seen, the sheets A 'and B are now at the entrance of the merger 904 and the sheet A has been transferred to the collecting station 906. Now that the transfer of sheet A to the collecting station has been completed, the next sheet of this sheet group, sheet A ', can now move from the entrance of the merger to the Collectors 906 are transferred, as shown in FIG. 12, in the time period from 200 ms to 400 ms (see reference number 904 R).
- FIG. HF corresponds essentially to that from FIG. HB, but group X has been replaced by group A and the sheet in merger 904 is now sheet B.
- the total cycle time for forming group A is 400 ms.
- an odd group or odd sheet group is a group in which the individual sheets belonging to the group are arranged offset from the paper web 910, as is shown in FIG individual sheets B and B 'can be seen.
- Such an offset results, for example, from the fact that the sheet feeder in the printer Device 902 a left-right print takes place, whereby the group end is on the left with respect to the central axis Z in the paper running direction.
- 11 and 12 is that from the paper feed device 902, which can be, for example, the cutting machine described above or a sheet feeder, paper or sheets can only be fed again when the collecting station 906 has issued the previous group has and is receptive again. This results in a reduction in cycle performance for odd groups, which is 50% for a two-sheet batch quantity.
- DE 34 33 497 AI describes a device for compiling sets of form sheets from form sheets belonging to a set.
- the compilation device consists of two recording stations which are arranged side by side.
- the receiving stations each receive a form sheet from two paper conveying paths running parallel to one another, with form sheets of the same form sheet set being collected in one of the two receiving stations.
- a special, perforated revolving conveyor belt with a vacuum suction block is used to convey the form sheets in the transverse direction, which is intended to increase the working speed while at the same time increasing the security against malfunctions.
- one of the two receiving stations of the compilation device is followed by a collecting station in order to feed the same form sheets to a form sheet set.
- the present invention has for its object to provide an improved method and an improved device for forming sheet groups from a plurality of sheets, which enables an increase in the clock performance when forming the individual groups.
- the present invention provides a method of forming groups of sheets from a plurality of sheets, comprising the following steps:
- step (b) if the sheets provided in step (a) belong to the same sheet group:
- the present invention provides an apparatus for forming sheet groups from a plurality of sheets, comprising:
- stopping means receiving one or more sheets from the sheet feeding means
- a collecting station that collects sheets of a group of sheets
- the sheets provided by the sheet feed device belong to the same sheet group, these sheets are transferred to the collecting station, and - otherwise, the transfer of one of the sheets into the collecting station and the retention of the other of the sheets in the stopping point means.
- the present invention is based on the knowledge that a significant increase in the performance of collecting devices for paper, as described above with reference to FIGS. 11 and 12, can be achieved by inserting a stop point in front of the collecting station, this stop point for example for a Sheet or can be provided for two sheets one on top of the other.
- This insertion of the stop which is capable of transporting and temporarily storing (buffering) a sheet or two sheets lying one above the other, achieves that in the case of an odd sheet group (see above) precursors, e.g. a merger that can be resumed at an earlier point in time since the first sheet of the subsequent sheet group is stopped in the stop point (buffer).
- the stop point according to the invention is arranged between a merger and a collecting station, the sheet feed device comprising a cutting device and a printer.
- the stop point is arranged between the sheet feed device and the collecting station, with this Embodiment the sheet feeder is designed such that it receives two paper webs arranged parallel to each other, prints them, merges them from the adjacent arrangement onto a common paper path and cuts them, so that at the exit of the sheet feeder the sheets of the individual webs to be grouped are arranged one above the other.
- the device is designed in such a way that the individual sheets are placed on a subsequent folder by a sheet feed device in the form of a cutting and printing device, the two sheets being provided next to one another in a first paper running direction, being transferred to the subsequent folder and out this in a second paper running direction, which is preferably perpendicular to the first paper running direction, are moved into this via the stop point according to the invention, which is arranged in front of the collecting station.
- the sheets provided are brought together in a common path in such a way that they are either arranged one behind the other in the sheet running direction, not overlapping, one behind the other in the sheet running direction, are arranged in a scaled manner or are arranged one above the other in the sheet running direction.
- a further stop point is provided between the sheet feed device and the merger, as a result of which a further improvement in the cycle performance can be achieved since the feed operation to the merger is now decoupled from the mode of operation of the cutting device.
- This further stop takes up the sheets provided, which has the advantage that, in the case of a merger which has already been filled, paper can be fed in again accelerated from the paper feed device and, if requested by the merger, paper can be fed immediately. pier can be reloaded, ie there is no unnecessary loss of time due to the complex cutting operation (approx. 20ms).
- the advantage of the present invention is that the clock performance of the paper handling system can be significantly increased compared to devices known from the prior art when processing odd groups.

- a control device 112 is also provided, which is connected to each of the components of the device 100. Sheets to be processed, e.g. Paper sheets, in a paper or sheet running direction P.
- a paper web 114 which is fed to it is printed and then the paper web 114 is cut in order to provide two single sheets 116 and 118 arranged next to one another in the sheet running direction P at the exit of the paper feed device 102.
- the single sheet 116 is arranged in the paper running direction P to the right of the central axis Z of the device 100, and the single sheet 118 is arranged in the paper running direction P to the left of the central axis Z.
- the individual sheets 114, 116 arranged side by side are transferred to the merger 104, which transfers them into a common sheet path, as indicated at 120 in FIG. 1A.
- the stop point device 106 connects to the exit of the merge 104, from which the sheets contained therein or the sheets contained therein are passed on to the collecting station 108 in order to form the desired sheet group there. Once formed, the collected sheets become a stack 122 from the collection station 108 to the folding unit HO, folded there and, if necessary, fed to a further treatment, such as inserting the folded sheets into an envelope.
- the control device 112 controls the overall sequence of the operation of the device 100 such that if the sheets transferred by the sheet transfer device 104 (merger) belong to the same sheet group, the transfer of these sheets to the collecting station is effected. Otherwise, the control function causes one of the sheets to be transferred to the collecting station 108 and the other of the sheets to be temporarily stored in the stopping device 106.
- the sheet feeder 102 is, for example, a combination of a printer and a cutting device or a sheet feeder that provides two separate sheets side by side for transfer to the merger 104.
- a previous stack X is already contained in the collecting station
- sheet A of sheet group A is located at stop point 106
- sheet A 'of sheet group A and sheet B of subsequent sheet group B are located side by side at the entrance of merger 104 provided.
- the further sheets B 'and C are already provided in the sheet feed device 102, but have not yet been completely cut.
- phase 3 shows phase 3, which occurs 300 ms after the start of phase 1.
- the complete sheet group A is contained in the collecting station 108, and the sheet B of the following group is held in the stop point 106, which makes it possible to simultaneously provide the further single sheets B 'and C at the entrance of the merger 104.
- the partially cut sheets C and D of the further sheet groups are already at the exit of the sheet feed device 102.
- the two sheets 116 and 118 are first provided adjacent to one another in the paper running direction and in the common sheet path 120 in the merger 104 transferred.
- the transferred sheets after they belong to the same sheet group A, are transferred to the collecting station 108.
- the same steps are carried out for all sheets in this sheet group A until the sheet pair is reached in which one of the sheets is assigned to a subsequent sheet group, namely sheet group B.
- the last sheet A "" belonging to the current group is added to the collecting station and sheet B is held back in the stop station device 106.
- the sheet B contained in the stopping point is transferred to the collecting station and the remaining sheets of the sheet group B are transferred to the collecting station 108 in accordance with the steps set out above.
- the apparatus 100 makes this possible by the fact that the control device is operative to control the sheet feed device 102 and the sheet transfer device 104 in order to transfer all sheets of a sheet group into the collecting station 108, in the event that one of the sheets of the adjacent sheet pair is not belongs to the current sheet group, the control device is operative to transfer the last sheet of the current sheet group to the collecting station and to hold back the first sheet of the subsequent group in the stop station device 106. After the stack of the current sheet group has been extended from the collecting device, the control device causes the retained single sheet to be transferred from the stop station device to the collecting device and subsequently controls the remaining components of the device in order to guide the respective sheets of this new group to the collecting station.
- the device according to the invention is configured such that the merger 104 transfers the two adjacent sheets on the common sheet path 120 in such a way that they Direction are arranged one behind the other, not shingled, as shown in Fig. IC and ID.
- the present invention is not limited to sheet feeding devices which only provide two sheets, but devices can also be used, for example a plurality of sheet feeders which provide three or more sheets side by side in the direction of sheet travel.
- FIG. 1A The operating principle of the device according to the invention, as shown in FIG. 1A, for collecting two-sheet groups is briefly explained once again below with reference to FIGS. 2 and 3, the flow diagrams shown in FIGS. 2 and 3 for different configurations of the individual components of the device 100 were set up.
- FIG. 2 shows a flowchart for the device 100 with the stop point 106, in which the output times for two-sheet groups are specified in milliseconds, these corresponding sheets being arranged in an odd manner (see above), the stop point length of the stop point device 118 being approx. 330 mm, and the cutting device or sheet feed device 102 causes the sheets to be fed at a speed of approximately 2 m / s, and the merger moves the respective sheets at a speed of approximately 4 m / s to 4.5 m / s s. 2 and 3, the times are plotted along the x-axis, and the corresponding components are indicated along the y-axis, i.e.
- the sheet feed device 102 the merger 104, the stop point 106 and the collecting station 108, wherein, as already in FIG 12, a distinction is made between the sheet in the merger in the sheet running direction P to the left of the central axis Z and the sheet in the merger in the paper running direction P to the right of the central axis Z, which is illustrated by the reference numerals 104R and 104L.
- the sheet in the collecting station is first Group X extended, which takes 150ms.
- a single sheet A of the sheet group A located in the stop point 106 is started, the extension from the stop point taking 150 ms.
- the single sheet A 'of the sheet group A lying to the left of the central axis Z in the sheet running direction is moved by the merger in the direction of the stop point 106, as is shown at 104L in FIG. 2. Extending a sheet from the merger takes 170ms.

- the individual sheet A With a predetermined offset of approx. 50 ms after the start of the extension of group X from the collecting station 108, the individual sheet A, which is already in the stop point 106, is started to be moved out of the same, which takes 115 ms.
- the individual sheet B of the following group which is also located at the merge entrance, is then started to be moved through the merger, which in turn takes 170 ms, and at the same time the sheet feed device 102 is started to provide the next sheets B 'and C, which Lasts 200ms.
- sheet A ' is transferred to stop point 106, the output speed of which is set such that the extension of this sheet A' takes only 95 ms, so that after about 265 ms, sheet group A consists of the single sheets A and A 'is in the collecting device 108, and at this time the individual group is started to be extended.
- the single sheet B is moved out of the stop point 106 into the collecting station, the single sheet B 'of this group having been moved beforehand, as can be seen in FIG. 3 .
- the resulting cycle time in this case is only 300 ms, which is 100 ms shorter than the cycle time required in a system according to the prior art.
- FIG. 4A differs from the example from FIG. 1 in that the stop point device 106 is a so-called double-level stop point for receiving two sheets lying one above the other, which leads to a further reduction in the cycle time required to to form a group.
- FIG. 4A shows the device according to this exemplary embodiment, and in this case the merger 104 is operated in such a way that when the two single sheets are transferred from the adjacent arrangement into the common path, this is done in such a way that the two sheets are arranged one above the other , and so be entered in the two-story stop.
- the two leaves B and A ' which are at the entrance of the merge 104, were simultaneously moved in the direction of the collecting station 108, so that they are arranged one above the other or at least one overlapping.
- the extent to which a complete covering or a scaled arrangement of the two single sheets is desired depends on the specific application.
- the stop length here is 165 mm, and the stop point, as stated, is double-decker.
- the initial situation is shown in which the previous stack X is in the collecting station 108, the single sheets A 'and B are at the entrance of the merger, the single sheet A is in the stop point 106, and the further sheets B' and C are provided in the sheet feeder 102 in the manner shown in FIG. 4.
- group X starts to move out of the collecting station 108, which takes 150ms.
- the individual sheets B and A 'at the entrance to the merger are started to be moved towards the collecting station, simultaneously, which takes 170 ms.
- the following sheets B 'and C are started to be made available by the sheet feed device 102, which takes 200 ms.
- the sheet A located in the stop point 106 is started to be moved out of it, the stop point here operating at a first speed, so that the extension takes 115 ms.
- the two sheets A 'and B are fed to the stopping place 106 in two levels, and the operating speed thereof is changed to a higher value in order to extend the single sheet A' from the corresponding one Stop level faster to accomplish, which takes 95ms.
- the single sheet B remains in the stop point and is moved out of the stop point 106 at the start of the transfer of the sheets B 'and C by the merger, as has already been described above with reference to the single sheet A.
- the total cycle time for forming a group in this example is 265 ms, so that the method is accelerated even further.
- FIG. 7A shows the device 100 according to this exemplary embodiment, which essentially corresponds to that from FIGS. 1 and 4, but in addition a further stop point 124 is inserted between the sheet feed device 102 and the merger 104 in order to decouple the cutting operation from FIG to provide the feed operation to the merger 104.
- This has the advantage that at any point in time when the merger needs new paper, such feeding can be accomplished immediately, i.e. there is no longer any need to wait until the time-consuming cutting operation (approx. 20 ms) has been completed.
- the sheets are fed into the merger 104, they are processed in accordance with the type as has been described with reference to FIG. 1 or FIG. 4.
- group X is started to move out of the collecting station 108, the collecting station being operated in such a way that this extension takes approximately 150 ms.
- the individual sheet A 'located in the merger (see reference numeral 104L) is started to be moved through the merger, with the start of moving the single sheet A out of the stop point 106 at the same time and at the same time as the start of the extension of the single sheet A from the Stop point is started to move the single sheet B, which is also located at the entrance of the merger, through the same, as shown at 104R.
- Extending the individual sheets from the stop point 106 upstream of the collecting station takes approximately 70 ms, and extending the individual sheets from the merger takes approximately 170 ms.
- the sheets B 'and C arranged in the further stop point 124 are extended at a time offset from the start of the sheet B being extended from the merger 104, which takes approximately 150 ms.
- the cutting machine 102 is activated in order to prepare the further sheets C and D and to transfer them to the stop point 124, which takes approximately 200 ms.
- FIG. 9A shows the device according to the invention in accordance with the further exemplary embodiment, which comprises a sheet feed device 102, a stop point 106, a collecting station 108 and an optional folder HO, the individual elements each being connected to a common controller 112.
- the sheet feed device 102 according to this exemplary embodiment is designed such that it receives two paper webs 150, 152 which run parallel to one another and are separated from one another, these two paper webs having already been provided with the corresponding information, for example by upstream printers or similar elements.
- the paper webs arranged next to one another with respect to the paper running direction P and the machine center axis Z are transferred to a common paper path, as is done by arrows 154 is shown.
- the paper webs thus guided one above the other are cut in order to provide the sheets of the individual groups, which are then passed on to the collecting station 108 via the stop point 106, from where they perform further processing, for example a fold in the folding unit in the illustrated embodiment HO.
- the sheets A 'and B which have not yet been cut, are ready, the fed paper webs already being arranged one above the other.
- the sheet group A was completed by moving the sheet A 'from the stop point 106 into the collecting station, and in the stop point 106 there is only sheet B of the sheet group B.
- the situation as shown in FIG Fig. 9D is substantially the same as that in Fig. 9B, except that now another group has already been formed has been .
- FIG. 10A A further exemplary embodiment of the present invention is again described in more detail below with reference to FIG. 10, a representation of the device according to the invention being shown in FIG. 10A.
- This device like the others, comprises a sheet feed device 102 which essentially corresponds to that which was described above with reference to FIGS. 1A, 4A and 7A, i.e. a feed device which provides individual sheets side by side in the paper running direction, these sheets in the Sheet feeder 102 printed and then cut.
- the feed and provision of these individual sheets takes place in the feed device 102 in a first paper running direction Pl.
- a follow-up folder device 160 is connected downstream of the sheet feed device 102 in the first paper running direction Pl, and this device 160 is connected in one second paper travel direction P2 to the stop point 106 according to the invention and then to the collecting station 108, which, as can be seen, outputs the collected sheets to a folding unit HO in a third paper travel direction P3.
- the sheet feed device 102 transfers the individual sheets arranged side by side to the following folder device 160, which transfers them to the stop point 106 in the second sheet running direction P2.
- a preceding sheet stack X is located in the collecting station, a first sheet A of sheet group A is arranged in the stop point 106 and in the following folder there is another sheet A 'of sheet group A and a first sheet B lying next to one another with respect to the first paper running direction Pl sheet group B.
- the following sheets B 'and C are already provided.
- the paper running directions P1 and P3 are essentially parallel to one another, whereas the paper running direction P2 is substantially perpendicular to the two paper running directions mentioned above.
- other configurations are also possible.
- the present invention offers considerable speed advantages over the systems as known in the prior art, since the provision of the stop point between the merger and the collecting station enables the merger to be reloaded earlier, since the first sheet of a subsequent group in the stop is temporarily stored or withheld.
- a further advantage results from the fact that a further stop point can be arranged at the entrance to the merger, so that a pair of sheets is always provided at the entrance to the merger, so that the merger can be supplied immediately upon request, without the time-consuming cutting steps having to be carried out first.
