    专利说明:

    The invention relates to a method for controlling or regulating a speed of at least one conveyor belt consisting of at least one conveyor belt sheet boom 16 for signatures for producing a defined overlap spacing at a delivery point of the sheet boom 16, with the sheet boom 16 at a receiving point signatures each of different or identical sizes can be stored in a temporally discontinuous or continuous sequence by means of an output device 15.
    In post-processing or further processing components of the printing and packaging industry, in which individual more or less flat signatures such as isolated sheets, isolated folded products, etc. are processed and transported to another unit for transport, so-called display devices or displays are used . Such display devices usually consist of at least one conveyor belt on which the signatures are placed in order to be transported to a next unit such as a stacking device.
    To transport the signatures, however, these are not stored and transported individually and separately from one another on the at least one conveyor belt, but the signatures are mostly stored and transported in the form of an imbricated stream, with the signatures partially overlapping in an imbricated stream or a scale . As a result of this overlapping, the transport speed of the delivery device or the transport speed of the at least one transport belt can be reduced, so that the signatures can be guided better due to the lower transport speed of the transport belt.
    With such an imbricated stream, however, it is imperative to ensure a uniform imbricated spacing so that the imbricated can be separated into individual signatures again by appropriate devices such as a pincer gripper, suction gripper or a conveyor chain.
    In conventional printing machines such as offset printing machines, gravure or flexographic printing machines with a fixed print image that remains constant over the edition print and thus with the format and fold type of the signatures constant over the edition print, this is relatively easy to implement, since the speed only changes when the printing speed is changed of the conveyor belt must also be adjusted. If the printing speed remains the same, however, the shingled spacing is always the same, at least in a tolerance range that depends on the delivery quality, etc., since all signatures of a print job or edition print have the same dimensions and page numbers and are continuously stored on the delivery 16, for example by means of a paddle wheel of a folding unit.
    However, the constancy of the signature dimensions and / or the number of pages in production facilities for digital and thus variable printing form printing facilities with downstream post-processing components such as cross cutters, funnel or combination folding units is no longer given over a production period, because on the one hand, subjects directly behind one another due to the variable printing form printing process can be produced with different dimensions, from which, with appropriately suitable post-processing components, successive signatures with mutually different dimensions can result.
    On the other hand, due to the possibility of sequential printing of all pages belonging to an intermediate or end product, such variable printing form production facilities are able to successively produce signatures with different page sizes and thus with different numbers of collecting processes of the sequentially printed pages.
    Such folding units for the production of signatures with different dimensions and / or page counts are known, for example, from DE102012103729 A1, EP1209000A1, DE10213978 or from DE102009039278A1.
    Thus, in such digital, printing form variable production facilities at a receiving point on the boom 16 successively signatures of different dimensions and / or different page numbers can be stored. When signatures with different dimensions are displayed, even if the signatures are deposited continuously over time on the boom 16, an unequal spacing of the scales in the area of the pick-up point results. H. where an output device such as a paddle wheel transfers the signatures to the boom.
    When displaying signatures with different numbers of pages, the display of the signatures is not necessarily carried out in a continuous sequence due to the mostly different number of collecting and / or folding processes, but the signatures are usually transferred to the boom in a discontinuous sequence at a constant speed of the delivery belt in turn results in an uneven spacing of the scales.
    With a correspondingly large time interval between the filing of two subsequently transferred signatures to the boom, the case may arise that no more scales are formed on the boom, but that the signatures are designed as individual copies.
    From the prior art, however, only booms or booms consisting of conveyor belts are known, which are operated with a substantially uniform conveyor belt speed, only the printing speed is taken into account here.
    The invention is therefore based on the object of creating a solution which makes it possible, even when displaying signatures with the same and / or different dimensions and / or different page numbers with continuous or discontinuous display of the signatures, a uniform scale spacing of the to achieve a shingled stream of imprinted signatures.
    This object is achieved by a method according to claim 1 and by a device according to claim 11. In the method of the type described at the outset, the object is achieved according to the invention in that at least one conveyor belt of the sheet delivery device is operated at a non-uniform speed.
    Such a method has the advantage that completely different signatures can be produced one after the other and thus without interrupting the production process and that nevertheless at the delivery point of the boom, i. H. where the signatures are transferred from the delivery to other components such as a chain conveyor etc., a constant, definable overlap spacing is always guaranteed, so that a safe and reliable transfer of each signature is ensured.
    In a further embodiment of the invention, the speed of at least one conveyor belt has a changing course, so that due to the negative speed of the time-changing course there are opposite directions of movement.
    With such an embodiment of the invention, on the one hand, signatures lying on the conveyor belt can be passed on to appropriate acceptance devices or, for example, to a subsequent conveyor belt, on the other hand, a newly interpreted signature can also be picked up, so to speak, in which the conveyor belt is contrary to the actual main - Moving direction.
    In a further advantageous embodiment of the invention, the speed of at least one conveyor belt has a swelling curve, so that due to the lowering of the speed to a maximum of zero, there is only one movement in only one direction of movement. Avoiding the reversal of direction reduces both the mechanical loads and, in particular, the risk of the signatures lying on the relevant conveyor belt slipping, which may already form a scale.
    In a particularly advantageous embodiment of the invention, in which the boom must, however, consist of at least two conveyor belts, at least one first conveyor belt has a speed with an alternating course and at least one second conveyor belt has a speed with a swelling course. It is also evident that in each case at least one separately drivable conveyor belt is operated at a continuous speed.
    With such a configuration, the creation of a scale or a scale flow can be distributed over several conveyor belts and thus over a longer distance, so that a high degree of variability in the design of the subsequent signatures is possible. Furthermore, the accelerations and thus forces acting on the signatures are minimized as far as possible.
    Preferred developments of the invention emerge from the dependent claims and the following description. Various exemplary embodiments of the invention are explained in more detail with reference to the drawings, without being restricted thereto. 1 shows a schematic digital printing device with a further processing component and display; FIG. 2 shows an example of an imbricated flow on a display with a uniform spacing of the scales. FIG. 3 shows an example of signatures on a display with a temporally discontinuous deposit Signatures with different dimensions Fig. 5 shows an example of a display of signatures with different dimensions and constant spacing of the scales; Fig. 6 shows an example of the display of signatures with partially unequal scales. Fig. 7 shows a boom consisting of two conveyor belts
    1 shows, by way of example and schematically, a digital and thus variable printing form printing machine 1, which is suitable for printing and subsequent further processing of the printed substrate web 3.
    By means of the unwinder 2, which can also be designed as a roll changer 2, the printing substrate web 3 is unwound from a roll and fed to the printing devices 4 during the printing process. The unwound printing material web 3 optionally provided with a web tension then passes through at least one printing device 4 in the printing direction 5 or web running direction 5, with which the printing material web 3 is printed at least on one side and at least in one color. Frequently, as also shown by way of example in the diagram in FIG. 1, the printing material web 3 is printed in four colors on both sides, which is why a printing machine 1 with two printing devices 4 is shown in FIG. 1.
    The printing devices 4 are digital printing devices such as an inkjet printing unit or toner-based printing units. Since no fixed printing forms such as printing plates are used here, the print content and thus also the corresponding print format are completely variable.
    After printing, the printing substrate web 3 can optionally also be dried or post-treated in some other way, although such devices are not shown in FIG.
    Alternatively and not shown in Fig. 1, it is also possible that a printed substrate web 3, which was preferably printed with a printing form variable printing process and rewound into a roll, is unwound by an unwinder 2 or roll changer 2 and with or without additional printing is fed directly to at least one folding device for separation into individual signatures 20.
    Optionally, the printing material web 3 can be guided over a first folding device 13 such as a first longitudinal folding device 10, for example designed as a fold former, in which the printing material web 3 or partial webs (not shown) separated from the printing material web 3 for the first time, mostly in the printing direction 5 be folded.
    Subsequently, the optionally already folded printing material web 3 is divided by cross cutting into individual signatures 20 by means of the separating device 11 designed as a pair of cutting cylinders 12, optionally additional folds can also be made transversely to the printing direction 5 by means of various folding devices 13 such as folding cylinders. However, it should be noted here that the folding unit shown in FIG. 1 is designed purely by way of example as a so-called combination folding unit with folding devices 13 in the form of folding cylinders. The present invention can be used with all post-processing components that design individual signatures 20, for example also cross-cutters, sheeting, funnel folding units, combination folding units or also units which process sheets or signatures 20 as output products. A signature 20 is an isolated product such as an unfolded sheet, single or multiple folded products; in the packaging area, for example, any type of roughly flat products such as cardboard boxes, sections and blanks, with or without punchings, etc. can be.
    In the folding mechanism shown in FIG. 1, the signature 20, which is folded once or several times, is fed to an output device 15 by means of a ribbon line 14, and the signature 20 is deposited on the boom 16 with the output device 15. The output device 15 is, for example, a paddle wheel known from the prior art or, for example, output by means of a ribbon line 14. The point or the area in which the signature 20 is deposited on the boom 16 is referred to as the receiving point 22, since there the Cantilever 16 according to the invention which receives the signatures 20.
    The boom 16 consists of at least one conveyor belt 30, it is thus also possible that several conveyor belts are used one behind the other in the delivery direction 17.
    The folding unit shown by way of example in FIG. 1 is able to successively produce signatures 20 with different dimensions and / or page counts. Even if signatures 20 of different sizes are laid out one after the other in a chronologically continuous sequence, they have an unequal spacing of scales at a constant speed of the conveyor belt 30. Even if signatures 20 with different page sizes are produced one after the other, the result is a chronologically discontinuous sequence of the signatures 20 deposited by the output device 15 on the boom 16 due to the different frequency of collecting processes.
    Fig. 2 shows a continuous display of signatures 20 by means of an arm 16 designed as a conveyor belt 30. The signatures 20 all have the same page circumference and the same dimensions, so that the signatures 20 on the arm 16 as from the state Known in the art as a scale 21 or scale flow 21, the signatures 20 partially overlapping in the scale 21.
    Due to the constant framework conditions such as product dimensions and continuous display over time, the imbricated stream 21 has a uniform imbricated spacing a, which is indispensable for further receiving the signatures 20, for example by means of pincer grippers of conveyor chains.
    Fig. 3 shows an example of a display of successively stored on the boom 16 signatures 20, which have the same dimensions at least in the direction of delivery 17, but are collected differently due to the different page sizes, so that the time sequence of the display of the signatures 20 takes place discontinuously.
    Thus, at a constant delivery belt speed 18 there is an uneven scale spacing, as can be seen from the significantly different scale spacings a1 and a2 between the signatures 20-1 and 20-2, in the extreme case there is no scale due to a lack of overlap of the signatures 20 21 more before.
    4a shows the imbricated stream 21 by way of example with signatures 20 laid out one behind the other with at least partially different page sizes, in which the at least one conveyor belt 30 of the sheet delivery 16 is operated at a non-uniform speed by means of the method according to the invention.
    As can be seen by way of example in FIG. 4a, first two first signatures 20-1 with a first page circumference are placed on the arm 16 in the scale 21 in chronological order, followed by a second signature 20-2 with a second page circumference deposited on the boom 16. Since the second page circumference exceeds the first page circumference, more collecting processes, or even one collecting process at all, are necessary to produce the second signature 20-2 than to produce the first signature 20-1, so that the chronological order of the filing of the two different signatures 20- 1 and 20-2 is discontinuous. In order to still achieve a constant, definable and also variable scale spacing a as shown in FIG. 4a, at least one conveyor belt 30 or, as shown by way of example in FIG. 4a, the at least one conveyor belt 30 of the boom 16 is operated at a non-uniform speed.
    Thus, the diagram shown in Fig. 4b shows the course of the conveyor belt speed 18 over time when the speed of at least one conveyor belt 30 or the one conveyor belt 30 has an alternating course with thus opposite directions of movement.
    The speed is still constant during the display of the first signatures 20-1, then reduced and even accelerated into the negative speed range and thus a direction of movement opposite to the actual transport direction, in order to then return to the original or that for the display first signatures 20-1 to be increased with uniform scale spacing a. The reduction in the speed of the conveyor belt is therefore necessary in order to be able to compensate for the delayed, because discontinuous, filing of the second signature 20-2 with the second page circumference.
    The conveyor belt speed 18 in FIG. 4b can also be rounded or alternating sinusoidally. It is also possible to make the amount of the negative conveyor belt speed 18 equal to or greater than the amount of the positive conveyor belt speed 18, although not shown in FIG. 4b. Furthermore, it is possible to design the falling flank with a different slope than the rising flank of the conveyor belt speed curve, depending on the sequence and the required adaptation of the conveyor belt speed 18 to the sequence and configuration of the signatures 20.
    Even if not shown in FIG. 4b, the conveyor belt speed 18 can assume a different value after the renewed acceleration than before the conveyor belt speed 18 was decelerated.
    The diagram shown in Fig. 4c shows the course of the conveyor belt speed 18 over time when the speed of at least one conveyor belt 30 or the one conveyor belt 30 has a swelling course with thus only one direction of movement.
    The speed is still constant when the first signatures 20-1 are displayed, in order to then be reduced to a low value of the conveyor belt speed 18, so that the transport direction always remains in the same direction of movement in order to then return to the original or the to be increased for the display of the first signatures 20-1 with a uniform scale spacing a. The reduction in the speed of the conveyor belt is therefore necessary in order to be able to compensate for the delayed, because discontinuous, filing of the second signature 20-2 with the second page circumference.
    The conveyor belt speed 18 in Fig. 4c can also be rounded or sinusoidally alternating, it is also possible to make the amount of the negative conveyor belt speed 18 equal to or greater than the amount of the positive conveyor belt speed 18, although not shown in Fig. 4c. Furthermore, it is possible to design the falling flank with a different slope than the rising flank of the conveyor belt speed curve, depending on the sequence and the necessary adaptation of the conveyor belt speed to the sequence and configuration of the signatures 20.
    Even if not shown in FIG. 4c, the conveyor belt speed after the renewed acceleration can assume a different value than before the deceleration of the conveyor belt speed.
    FIG. 5a shows the imbricated flow 21 by way of example with signatures 20 laid out one behind the other with at least partially different product sizes, represented by different product lengths in the example of FIG. 5a.
    Thus, initially 4 short signatures 20-3 are placed on the display, after the production of the fourth short signature 20, for example, the production is switched to longer signatures 20-4 of a subsequent print job. Due to the larger dimensions of the longer signatures 20-4, this results in a different time sequence of the deposition from the output device 15, so that an adjustment of the conveyor belt speed 18 is necessary to ensure a constant overlap spacing a.
    As can be seen in Fig. 5b, this the conveyor belt speed 18 is lowered for the first of the four long signatures 20-4, then again to ensure the same, definable scale spacing a on that for the continuous display of the following long signatures 20-4.
    Although not shown graphically in the figures, a combination of the possibilities shown in FIGS. 4 and 5 is also possible in practice and is possible through the present invention to ensure a definable scale spacing, namely that the following signatures 20 at least partially differ both in terms of the dimensions, in particular in the extent of the delivery direction 17, and in terms of the side circumference.
    However, a defined scale distance a must not only be understood to mean reaching an always constant scale distance a, this can also be defined in accordance with the requirements and thus changed in a targeted manner. FIG. 6a shows an exemplary embodiment in this regard, in which different print jobs, each with a plurality of identical signatures 20, are produced one after the other.
    In the example shown in FIG. 6a, a first print job consists of the four first signatures 20-5, the second print job consists of the four second signatures 20-6. Since the printing process as well as the changeover of the subjects of the respective print jobs takes place without interrupting the printing process, the successive print jobs would be laid out one after the other without interruption.
    In order to obtain a defined separation of the signatures 20-5, 20-6 associated with the respective print jobs in spite of the uninterrupted printing process, the present invention can also control that between the signatures 20-5 of the first print job and the signatures 20 -6 of the second print job a defined larger scale spacing a 'is generated. For this purpose, after the last signature 20-5 of the first print job has been deposited, the conveyor belt speed 18 is correspondingly increased for a short time in order to then slow down again to the conveyor belt speed 18 required to produce the overlap spacing a. A specific gap can thus be created between the signatures 20 of the different print jobs.
    Although not shown in FIG. 6a, it is also possible to design the scale distance between the signatures 20-6 of the second print job to be different from the scale distance a of the first print job, so that in this case the conveyor belt speed 18 at the second print job deviates from the conveyor belt speed 18 of the first print job.
    However, since a display can also consist of a plurality of conveyor belts, there is a large variety of options for varying the speeds of the individual conveyor belts or depending on the gradation of the dimensions and / or the temporal continuity of the display of the signatures 20 graded over several conveyor belts.
    Fig. 7 shows an example of an output device 15 with a delivery, the delivery of two separately drivable conveyor belts, namely a first conveyor belt 30-1 and a second conveyor belt 30-2, the terms first and second conveyor belt 30 only serve to distinguish and do not represent any information regarding their arrangement in the extension of the delivery direction 17, so that the second conveyor belt 30-2 can also be arranged directly on the output device 15 and thus in the area of the receiving point 22 in the extension of the delivery direction 17.
    Depending on the gradation of the product dimensions, it may be necessary for the conveyor belts that can be driven separately from one another to have the same and / or different temporal progression of the respective conveyor belt speeds 18.
    For example, the first and the second conveyor belt 30-1, 30-2 can both have a swelling course of the conveyor belt speed 18-1, 18-2, or both can have an alternating course of the conveyor belt speed 18-1, 18-2. However, it is also conceivable and, depending on the relevant parameters, also advantageous if a conveyor belt 30, for example the first conveyor belt 30-1, has an alternating profile of the conveyor belt speed 18-1 and the second conveyor belt 30-2 has an increasing profile of the conveyor belt speed 18-2 having.
    It is, for example, also possible and, depending on the relevant parameters, also advantageous if a conveyor belt 30, for example the first conveyor belt 30-1, has a swelling or changing course of the conveyor belt speed 18 and, for example, the second conveyor belt 30- 2 has a continuous conveyor belt speed 18-2.
    With a corresponding change in the production parameters such as changing the dimensions of the signature 20 or the temporal continuity of the display of the signatures 20, both the time courses and the amounts of the respective separately driven conveyor belts can also change accordingly.
    8 shows an embodiment of the delivery with three separately drivable conveyor belts 30-1, 30-2 and 30-3. Analogously to the description of FIG. 7, here too the courses of the conveyor belt speeds 18-1, 18-2, 18-3 of the respective conveyor belts 30-1, 30-2, 30-3 can be identical to one another and / or different from one another.
    For example, all three belts can be operated at continuous, albeit possibly differently in terms of their amounts, conveyor belt speeds 18, or at least one of the conveyor belts has an increasing or alternating course of the conveyor belt speed 18. In principle, any combination of the course of the conveyor belt speed 18 is conceivable and technically possible.
    With regard to the possibilities for determining the required conveyor belt speed 18 or speeds 18, both with regard to their amount and with regard to their temporal progression (swelling, changing, continuous), there are essentially two different approaches.
    Thus, for example, the time at which each signature 20 is deposited on the display at the receiving point 22 can be calculated by means of a printing machine or folder computer not shown in one of FIGS. 1 to 8 as well as the dimensions of the signatures 20 already deposited on the display as well as the dimensions of the signature 20 to be deposited next on the display are known. Based on the geometry, time and speed relationships, the required advance of the conveyor belt 30 until the subsequent signature 20 is deposited can be calculated as a function of the defined overlap spacing a, from which the course and / or the amount of the conveyor belt speed 18 or conveyor belt required for this can also be calculated speeds 18 can be calculated.
    It is basically irrelevant here whether the display consists of one or more conveyor belts. Due to the greater variance of the control options when several separately drivable conveyor belts are present, a logic with regard to the gradation of the respective conveyor belt speeds 18 is thus preferably stored in the control, although not mandatory.
    However, it is also possible that the control or regulation of the conveyor belt speed 18 is carried out on the basis of a detection of the leading edges of the respective signatures 20. For this purpose, appropriate electrical or opto-electrical sensors are preferably installed either before the output device 15 and / or after the output device 15 in the area of the receiving point 22 and preferably at the delivery point 23, with which the edges of the signatures 20 can be detected. Such a detection can either be used as the sole input variable or to validate the above-described computational determination of the position of the signatures 20. The use of corresponding sensors, not shown in the figures, offers the advantage that the actual scale spacing a at the delivery point 23 is recorded and can therefore not only be controlled but also regulated.
    In the event that the signatures 20 are not in the form of a scale 21, in which the signatures 20 partially overlap, but rather as individual signatures 20, which do not overlap, are designed directly at the receiving point 22, when the Boom 16 from a plurality of conveyor belts 30 from the individually laid out signatures 20 in the area of the receiving point 22 by corresponding gradation of the conveyor belt speeds 18 in the area where two conveyor belts 18 are adjacent to one another, a scale 21 can be formed.
