Definitions

  • the present invention is based on the fundamental digitization, which is increasingly also affecting the printing industry.
  • the present invention therefore relates to a system, preferably in the form of a saddle stitcher, which essentially consists of a transport chain which is roof-shaped in the upper region, along which one or more printed products, preferably in the form of folded sheets, can be transported astride, and preferably as a brochure to be stapled in an intermediate stapling station, according to the preamble of claim 1.
  • This mode of transport can also be used on non-stapled, assembled printed products, which may also be in the form of a combination of folded sheets.
  • These folding sheets are generally transported along the transport chain designed as a collecting chain to a stop point, and these folding sheets are then passed on from there via at least one feed device, also called a “delivery”, to a cutting apparatus in which the folded sheets or. the assembled brochure can be cut to size.
  • the invention pursues the synchronous transfer of a printed product to the delivery, which is also regulated to the different thicknesses of such a printed product at the same time, so that both the transfer and further transport of the printed product is individually tailored.
  • roller segments 46 cooperate with the feed roller 44 to exert a clamping force on the opposite sides of the printed product, to then grip it firmly and move it up to a second nip 50 which is between a plurality of pressure rollers 52 and the feed rollers 44 is trained.
  • the pinch rollers 52 and the feed rollers 44 operate to apply a clamping force to the opposite sides of the signature to grip the printed product as it moves up from the saddle 18.
  • the essence of the present invention is now to also base that task, which consists in the feed rollers of the delivery depending the measured thickness of the printed product, as required, also during each production cycle.
  • All of the underlying criteria of the task extend to the entire operational speed range of the system, to all format sizes and thicknesses of the printed products, and to the behavior of the respective paper material from which the individual folded sheets are made.
  • the object of the invention is achieved in that a number of units of this system act interdependently to one another, namely:
  • the printed products made with a number of folded sheets or the brochure made from them lie on a saddle-shaped collection chain (see definition list) and are transported towards the stop.
  • the drivers integrated in the collecting chain which act on the rear edge of the folded sheets and, in operative connection with the collecting chain, ensure the targeted transport of the folded sheets, so that they then be able to slide under the folded sheet through the progress of the collection chain.
  • sensors are installed in the immediate vicinity of this stop, or also integrated therein, which are capable of immediately recognizing a paper jam and triggering relieving measures which also serve to protect the machine.
  • Jam switches, camera systems, photocells, etc. are preferably installed for this purpose.
  • sensors are also provided, which serve as feedback for the position control of the printed product, preferably in the form of photocells, camera systems, etc.
  • This stop indicates the final positioning of the folded sheet, respectively.
  • the brochure or the printed product in general has a multiple function, namely that it exercises a certain nominal fixed stop position in relation to the transported printed product as the end location, but not exclusively in the conventional manner as a fixed stop station.
  • the stop With its special design and in operative connection with the controlled transport of the printed product, the stop thus fulfills a double function, which is characterized in the immediate area of the stop by horizontally / vertically superimposed movements of this printed product.
  • the stop in the final phase of the positioning of the printed product, there is a coordinated, control-dependent interdependency between the horizontal movement of this printed product and its vertical transfer, the stop then, as already explained, has a double function, namely on the one hand to ensure the end position of the brought-in printed product and on the other hand at to prevent this from tilting during vertical movement.
  • the stop then absorbs counter-movements which could lead to a tilting moment acting on the printed product, which could cause the printed product to tilt.
  • the position-related setting of the stop and the continuous monitoring of the process are preferably carried out by stored control profiles, the main control being able to regulate according to adaptive principles. Furthermore, the main controller is also able to provide a predictive / anticipatory control that applies to all units in the system.
  • the sword then takes on three fixed positions as part of the ejector, which are either predefined positions or continuously freely defined become.
  • “Pos. Abben” is the highest position of the sword, and it forms, as it were, its turning point, at which the transfer of the folded sheet to the conveyor belts of the delivery is completed.
  • “Pos. Bottom” is the lowest position of the sword as a reversal point; the sword dips down to this position so as not to collide with the subsequent printed product on the collection chain.
  • “Pos. Zero” represents the neutral position from which the sword comes into operation for the next printed product.
  • Regulating device according to the thickness of the printed product According to the invention, the delivery is expanded with a device which has a mechanism which also adjusts itself to the thickness of the printed product being conveyed at each cycle.
  • the starting point here is the detection of the thickness of the delivered, i.e. the printed product to be discharged.
  • the control is set up in such a way that this thickness can potentially or actually vary or be different with each production cycle. Accordingly, those differences in thickness within a job that are relevant for the recording of the printed products by the delivery are also recorded continuously.
  • a predetermined tolerance is taken into account by the control.
  • the range of thicknesses can advantageously be managed by an MIS (see definition list), whereby the thickness of the printed product can also be calculated by the number of folded sheets and their thickness.
  • a direct thickness measurement of the printed product is carried out, it is advantageous if such a thickness measurement takes place before stapling or, if need be, is already fixed there.
  • the detection of the thickness of the printed product is therefore based on the original when it comes to a symmetrical detection of the respectively measured thickness of the printed product on the one hand against the center of the collecting chain and on the other hand against the center of the sword belonging to the ejector.
  • the essential aspect according to the invention thus relates to the symmetrical alignment of the thickness of the printed product on the one hand with respect to the center of the collecting chain and on the other hand with respect to the center of the ejector sword belonging to the ejector.
  • This adjustment takes place continuously and is preferably accomplished by an electric motor, typically a servo motor, by means of which the symmetrical adjustment with respect to the measured thickness of the printed product takes place.
  • This is done by operating two symmetrically mounted swivel arms on both sides of the delivery area of the delivery, whereby each pair of swivel arms is positioned in relation to the print product to be detected via a "double cam" when it comes to opening a print product according to the measured thickness create.
  • This cam disk is rotated through a toothed belt gear by a certain angle, so that the cam disk takes up the opening due to the new angular position, which is the cause of a certain opening dimension.
  • the swivel arms arranged in pairs run parallel to one another in the vertical state in the normal state, and they have a bearing opposite the inlet area of the delivery, which is formed on abutting rollers, in such a way that they spread out angularly from above to detect the thickness of the printed product being conveyed out arises at the bottom, ie, these roles belonging to the two swivel arms fulfill the function of a hinge point, these roles being unwound to one another when spreading in a fixed manner.
  • the spread for detecting the thickness of the printed product being conveyed can also be achieved in such a way that the swivel arms operating in pairs can now open parallel to one another; For reasons of stability, this then presupposes that both ends of the swivel arms are preferably braced with one spring element each.
  • the set opening of the swivel arms to one another, which are supplemented by the integrated infeed rollers on the printed product side, is predetermined by a corresponding rotation of the cited cam, these swivel arms taking a stabilized position in that a spring is arranged at the end in the area of the infeed rollers, the force of which is also exerted on the Cam works.
  • a closed cam should preferably be dispensed with, so that e.g. in the event of a jam, the swivel arms could still deflect.
  • the system should be equipped with optical sensors, such as photocells, camera systems, etc., so that the position of the printed product in the delivery conveyor belts can be recorded at any time and tracked and evaluated on the way to the downstream cutting device. This allows a permanent correction to be made to the position of the feed rollers.
  • the adjustment as such as well as its degree can basically be carried out in “on-the-fly” mode, whereby only the speed of the collection chain could be at best.
  • Order data from the MIS (see list of definitions) or from your own order data system usually include: the format data of the individual folded sheets, as well as format data of the print product, such as cut width and length, as well as extensive all other data that is mandatory or situational for a specific one Order are necessary.
  • the control can also calculate the thickness of the respective printed product from the data of the individual folded sheets.
  • the main controller is also loaded with those algorithms with which all production-relevant values of the system can be recorded. In particular, this main control is able to calculate those values which are drawn for the control of the free width of the feed rollers to one another; this is preferably done by a servo motor, which acts mechanically on the cam disc (s).
  • order data from an MIS or from your own data system preferably lead to the activation of stored control profiles, which in particular record the format data of the individual folded sheets, that of the brochure, such as cut width and length and other data that are necessary for the qualitative implementation of the order are required.
  • the main control preferably also contains algorithms which continuously calculate the thickness of the brochures from the production of the individual folded sheets.
  • the infeed of the delivery specified by the infeed rollers is set to the correct free width depending on the thickness of the printed product, and for each product cycle.
  • the setting position of the infeed rollers belonging to the delivery can be monitored by sensors such as photocells, camera systems or similar systems and readjusted in case of deviations in "on-the-fly" mode via control. If a jam is detected, the infeed rollers open as wide as possible; if the monitoring determines that double take-off has taken place, the feed rollers open moderately to compensate for these differences in thickness; if the printed product has differences in thickness from one part to the other of the printed product compared to the folding symmetry, the feed rollers also open appropriately in order to master this new starting position.
  • the infeed of the infeed rollers is adjusted according to the value measured by the thickness control. If an incomplete printed product is recognized and there is no thickness measurement available, but the control is connected to an MIS, the value can be calculated based on the values known from the MIS (thickness of the individual folded sheets) and thus the correct width of the inlet (printed product thickness) can be set.
  • the main advantages of the device described (infeed rollers with associated parts) as part of the delivery can be seen in the fact that the combination of the cam disc and the type of self-propulsion (stepper or servo motor) makes it possible for the adjustment to be made from one production cycle to the next can, whereby of course the time-critical process must be taken into account.
  • the thickness setting is set symmetrically to the center of the collecting chain. This symmetrical thickness setting is carried out independently by two freely supported swivel arms and a double cam disc. In the event of incorrect pulling of folded sheets, the thickness of the printed product can be determined using the thickness measuring device, or if the missing folded sheets are known, the thickness values are obtained from the MIS and the device is used to set the timing precisely.
  • the invention is about a system, which is preferably designed as a saddle stitcher.
  • This essentially consists of a transport chain, which is roof-shaped in the upper area.
  • one or more printed products preferably formed by folded sheets, can be transported astride, collected, and optionally stapled in an intermediate stapling station, a stop adjustable in accordance with the format of the printed product being arranged in the transport direction of the printed product after the optionally operating stapling station along the further course of the transport chain is.
  • the stop in operative connection with interdependently operating means accomplishes a timely and format-stabilized delivery of the printed product.
  • the first means for the timely takeover when the printed product consisting of one or more folded sheets is conveyed out consists of a delivery, the delivery in its inlet area being designed for the first takeover of the exported printed product, which device corresponds to the measured thickness of this printed product is adjustable.
  • the device itself has two symmetrically mounted, mutually spaced and pair-operated swivel arms on both sides of the inlet of the delivery, the paired spacing of the swivel arms being effected by an intermediate and double-running cam disc, which spreads the swivel arms as a function of the rotating movement implemented measured thickness of the exported printed product.
  • the essentially horizontal swivel arms are on the ends in conjunction with each other over the entire area of the infeed of the delivery is provided with infeed rollers which manage the acquisition and further transport of the printed product being conveyed out.
  • the operating infeed rollers are also operatively connected via the swivel arms to a spring element, by means of which the infeed rollers are clamped to one another within the range specified by the cam disk as a function of the thickness of the printed product being conveyed out. This spreading of the swivel arms is therefore dependent on the thickness of the printed product being fed out, the feed rollers exerting a force fit on the printed product through the spring element.
  • the spread for recording the thickness of the printed product is carried out through an angular opening from top to bottom, i.e., the two rollers belonging to the swivel arms act as a hinge point, which, when spread, are unwound to one another by a certain amount of angle.
  • the spread for detecting the thickness of the printed product being conveyed can also be achieved in such a way that the swivel arms operating in pairs can also open parallel to one another; For reasons of stability, this then presupposes that both ends of the swivel arms are preferably braced with one spring element each.
  • the device itself is provided with an assembly (not shown in any more detail) which optionally makes a lateral adjustment of the device depending on the respective thickness of the printed product being conveyed out, in order to bring about an appropriate positioning of the device with respect to the symmetry of the thickness of the printed product being conveyed out.
  • This adaptable adjustment only comes into play when necessary, and it is also controlled in terms of timing, preferably during the kinematics of the swivel arms in order to produce the thickness of the printed product.
  • the second means for the timely conveying out of the printed product consisting of one or more folded sheets consists of an ejector, the then format-stabilized printed product preferably being fed to a cutting apparatus over the further course of the delivery after it has run in. With this When the printed product is conveyed out, there is a change in direction relative to the transport direction of the transport chain by or approximately 90 °.
  • the adjustable stop has a stop level directed towards the transport direction of the transport path, which, when it is being conveyed out, performs a coordinated stop and alignment function with respect to the front edge of the printed product consisting of one or more folded sheets, the collating chain being foldable in order to prevent transport-related collisions Transport fingers for conveying the printed product consisting of one or more folded sheets is equipped.

  • the controller 400 is in a reciprocal data flow system 401 with an MIS (Management Information System) 410, which system 410 in connection with the term "Industry 4.0" in the printing industry under the names such as "Finishing 4.0", " Print 4.0 "or” Web to Print "have become known. Basically, this means the digital transformation of the IT area and production technology. To solve these tasks, the MIS System 410 is used in particular.
  • MIS Management Information System
  • the integral control as such can be maintained by stored control profiles.
  • the main controller is also able to implement regulation based on adaptive principles; Furthermore, the main controller is also able to provide a predictive / anticipatory regulation.
  • a sword 503 remains below the delivery 130 in a neutral position ("position zero").
  • the sword 503 is waiting here, which is coupled to an ejector plunger 502 and which primarily forms the components of the ejector.
  • the ejector plunger 502 preferably has its own drive, and when the "trigger" command arrives, the movement kinematics are triggered.
  • the ejector 500 viewed as a complete unit, therefore starts its movement at the trigger position in order to generally transfer the printed product as uniformly as possible into the delivery.
  • This "trigger" point mainly depends on the speed of the collection chain, the product format and any manual correction, in such a way that the subsequent phases are initiated, depending on whether a defined or continuously freely definable speed threshold is exceeded or undershot.
  • the speed of the operative parts 502, 503 of the ejector 500 is directed to that of the collection chain or the conveyor belts belonging to the delivery. This means that if the speed of the collecting chain is increased, the ejector moves up faster accordingly. If the speed of the collecting chain is reduced, the ejector will move correspondingly slower.
  • the movement profile remains constant below the speed threshold. This defines a minimum speed of the ejector around which Ensure that the folded sheet is handed over to the conveyor belts of the delivery.
  • the ejector moves to a point that is referred to as "Pos. Above".
  • This "Pos. Above” is the upper reversal point of the sword 503, from here the position, “Pos. Below", is approached at a defined or continuously freely definable speed.
  • Figure 5 shows essentially the same elements as in Figure 1 , underlining the inventive development by means of a device 700 which can be regulated to the thicknesses of the printed products to be conveyed and which is operated by a motor 800 which acts in a data-linked manner 701 with the main control 400. Otherwise, the explanations below apply Figure 3 ,
  • Figure 6 essentially shows that Figure 1 , whereby from the Figure 6 the position of the delivery 130 is apparent, which contains the device 700 according to the invention.
  • Figure 7 shows the assembled delivery 130 and ejector 500, which are operatively connected to each other. More details on the structure of the delivery can be found Figure 2 and their description during the construction of the ejector 500 in Figure 4 and the description of which is presented. From this Figure 6 it can further be seen that the delivery 130 is provided by laterally arranged plates 710, 711, which are used to support the cross shafts 722, 732. These cross shafts span the entire feed area of the delivery. More details go out Figure 8 out.
  • Figures 8 and 9 show the effective structure of the device 700.
  • the starting point here is the detection of the thickness (601) of the conveying printed product.
  • the control See Figure 5 ) set up so that this thickness can potentially or actually vary or be different with each production cycle. Accordingly, those differences in thickness within a job that are relevant for the detection of the printed products by the delivery 130 are also recorded continuously. A predetermined tolerance is taken into account by the control.
  • the range of thicknesses can advantageously be managed by an MIS (see definition list), whereby the thickness of the printed product can also be calculated by the number of folded sheets and their thickness.
  • This device 700 has on both sides of the inlet area 790 of the delivery 130 two symmetrically mounted swivel arms 720, 730; 721, 731, the pairwise spacing of the swivel arms from one another being effected by an intermediate, double-running cam 750, which implements a spreading of the swivel arms as a function of the respectively measured thickness (601) of the printed product being conveyed out.
  • the essentially horizontal swivel arms connected to each other carry infeed rollers 760n, 770n over the entire inlet area 790 of the delivery 130, which accomplish the detection and further transport of the printed product being conveyed, regardless of its format size.
  • the operating infeed rollers 760n, 770n thus cover the entire infeed area of the delivery and are each supported on a connecting shaft 761, 762 between opposite swivel arms, namely 720 to 721 and 730 to 731, which means that the infeed rollers are also indirectly connected to one end of the swivel arm placed spring element 780, in such a way that the inlet rollers have a predetermined spread under spring force with respect to one another within the scope of the cam disk 750, depending on the thickness of the printed product being measured, and thus a non-positive connection is exerted on the printed product to be delivered.
  • FIG. 9 shows a pair of swivel arms on one side of the delivery, schematically also other rollers and associated conveyor belts 132 of delivery 130, which together ensure the further transport of the printed product.
  • the individual infeed rollers 760, 770 are shown here.
  • the spreading for detecting the thickness of the printed product being conveyed takes place in an angular manner from top to bottom, ie, the two rollers 741, 742 belonging to the swivel arms 720, 730 act as the hinge point 740, which, when spreading, unwind to one another by a certain angular amount.
  • the spread for detecting the thickness of the printed product being conveyed can also be achieved in such a way that the swivel arms operating in pairs can also open parallel to one another.
  • Each swivel arm 720, 730 preferably carries an opposing pin 751, 752 on each side in the plane of symmetry of the cam, which is caused by the rotation of the cam cause a force-supported spreading of the swivel arms along the profile.
