Definitions

  • Folded sheet A folded sheet, partial product of the printed sheet (paper printed on both sides) consisting of several sheet parts.
  • Brochure printed product consisting of at least one or more folded sheets.
  • Staple Consisting of wire, which is given this shape in a first step , and that it is pushed through the brochure and then bent over .
  • Stapling head cuts and positions the staple wire and forms the staple wire into a staple.
  • Stapling process Process in which at least one staple is pushed through the booklet and closed at the other end.
  • Stapling carriage Part of the stapling station on which the stapling heads are mounted.
  • Stapling station Staples a product using a staple while the stapling carriage is in sync with the transport chain.
  • Variable thickness Accepts brochures and / or sheet parts with different thicknesses.
  • Cutting device which has a front knife and two side knives and performs the cutting process consisting of a front cut and head-toe cut as a subsequent cut.
  • Saddle stitcher In a saddle stitcher, usually several folded sheets are collected on a transport chain, stapled in the stapling station and cut on three sides in the cutting device.
  • the saddle chain has a guide device, the upper section of which is designed in the shape of a cutting edge and whose ridge line defines the transport and stitching line, and an essentially roof-shaped support on which the sheet parts are transported astride.
  • Delivery machine component that transports the products after the stitching station into the feed to the cutting device. In the delivery there is a change of transport direction by 90 °, depending on the location of the cutting device, forwards or backwards.
  • Product infeed Conveyor belt, which transfers products to the cutting device after delivery.
  • the conveyor belt has mechanical stops which move synchronously with the cutting device.
  • Ejection phase By means of a device called an ejector, the product is lifted by the saddle chain until it is picked up by the conveyor belts in the delivery and transported further in the same.
  • On-the-fly Changes to e.g. settings, positions of devices etc. possible during operation.
  • MIS In connection with the term “Industry 4.0", terms such as “Finishing 4.0", “Print 4.0” or “Web to Print” are known in the printing industry. Basically, the digital transformation of IT and production technology is meant. In order to achieve these objects are M anagement I nformation- S ystems required.
  • the printed products are simply ejected into the delivery (see definition list) and then fed from the delivery itself to a cutting device, where they are trimmed to size.
  • the stabilization takes place only (if at all) by holding the printed products in the belts.
  • the force applied to change direction is only absorbed by the conveyor belts.
  • the horizontal position (center offset) of the printed products in the delivery is not “defined”, i.e. that the printed products slide through their kinetic energy to a greater or lesser extent on the ejector, depending on the situation. This means that the position in the display can vary by +/- a few millimeters.
  • the printed products still have kinetic energy in the transport direction at the point in time when the printed product reaches the conveyor belts of the delivery. This leads to a tilting torque of the printed product itself, with the second deflection in the delivery additionally and consciously (but unintentionally) exerting a moment on the printed product.
  • the product does not have a clearly defined position during delivery.
  • Out DE102004011973 A1 shows a saddle stitcher with at least one stapling station for stapling sheets, the stapling station being arranged on a stapling carriage movable in the longitudinal direction of a saddle chain during the stapling process and at least one ejecting unit for ejecting the sheets in the transport direction of the sheets behind the stapling station.
  • this saddle stitcher is characterized in that at least one acceleration and / or braking unit for accelerating and / or braking the sheets in the longitudinal direction of the ejection unit is arranged between the stapling slide and the ejector unit. The ejector unit then lifts the braked sheets from the saddle chain.
  • the sheets are collected, stapled, in order then, preferably in the braked state, in particular at a standstill, to be gripped by the ejector unit and lifted off, this in turn to ensure that they can be lifted off.
  • the invention aims to remedy this precisely against this.
  • Out EP1593526 B1 shows a saddle stitcher for brochures, with a stapling machine, an output station that is gradually fed with the brochures, a front cutter arrangement defining a cutting plane for trimming the brochures along a respective target cutting line and with transport components that transport the brochures from the output station to the front cutter arrangement.

  • EP1153764 A2 a saddle stitcher emerges which has at least the assemblies stapling slide, saddle chain, stapling lifting device, delivery and ejector. At least two of these assemblies each have their own drive and controllable motors are provided as the drive source. Each of these motors has a control unit which synchronizes the movement of one assembly to the movement of at least one other separately driven assembly.
  • the document EP 0 893 275 A1 discloses a system designed as a saddle stitcher, the system having a feed conveyor which is roof-shaped in the upper area, along which one or more printed products, preferably formed by folding sheets, can be transported astride, and wherein in the transport direction of the printed product along the further course of the feed conveyor a stop that is adjustable according to the format of the printed product is arranged, and wherein the stop, in operative connection with mutually interdependent means, accomplish a timed and format-stabilized conveyance of the printed product, the adjustable stop having a stop plane facing the transport direction of the transport path, which is opposite the front edge of the printed product consisting of one or more folded sheets exerts a coordinated stop function when it is conveyed out.
  • All 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.

Above” is the highest position of the sword, and it forms, as it were, its reversal point at which the transfer of the folded sheet to the conveyor belts of the delivery is completed. "Pos. Below” is the lowest position of the sword as the turning point; The sword dips down to this position so as not to collide with the subsequent printed product on the saddle chain. "Pos. Zero” represents the neutral position from which the sword comes into operation for the next printed product.
  • Order data from an MIS (see definition list) 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, those of the brochure, such as cut width and length and other data that are necessary for the qualitative implementation of the order are needed.
  • the main control preferably also contains algorithms which continuously calculate the thickness of the brochures from the production of the individual folded sheets.

  • the adjustable stop has a stop wall arranged on the front opposite the transport direction of the transport path, which functions as a saddle chain, which fulfills a stop and alignment function opposite the front edge of the folded sheets, the saddle chain also being equipped with foldable transport fingers. These fold in in the final phase of the hitting process so that the saddle chain can pass under the spread folded sheet.
  • the delivery has a number of adjacent moving belts which, in operative connection with an ejector operating on the underside of the ridge of the folded sheets, effect the conveying out of the folded sheets.
  • the ejector itself is equipped with a protruding sword, which conveys the folded sheets through a path running vertically from below into the delivery.
  • the interdependent operation of the transport chain, stop, delivery, ejector, cutting device is managed by a main control, this operation at least affecting the mentioned units of the system, which are operated by stored control profiles and / or by an adaptive and / or predictive control.
  • the sword belonging to the ejector moves to an upper reversal point (pos. Above) when the folded sheet is conveyed out. Furthermore, the sword moves to a lower reversal point (item below) after the folding sheet has been conveyed out. Furthermore, the sword assumes a neutral position (pos. Zero) from the lower reversal point (pos. Bottom).
  • FIG 1 shows an overall view of a saddle stitcher 100.

  • a collecting chain 110 has a guide device with an upper section which is pointed, that is to say roof-shaped, and the ridge line of which defines the transport and stitching line on which the folded sheets 200 are transported astride.
  • the individual folded sheets are assembled into a brochure in a stapling machine 120. The folded sheets rest on the saddle-shaped saddle chain, and they are transported from this direction to the stop 160.
  • the catches integrated in the saddle chain (not shown in detail in the drawing) fold which act on the rear edge of the folded sheets and, in operative connection with the saddle chain, ensure the targeted transport of the folded sheets , to the rear so that they can slide under the folding sheet as the saddle chain moves forward. This ensures that the folded sheets combined to form a brochure are no longer directly affected by the carrier in the final transport phase, but only by the friction or friction indicated by the saddle-shaped saddle chain. persistent force is transported to the stop.
  • the kinematics triggered on the individual folded sheets or on the brochure in general in this final phase are also important, namely to the effect that the printed product opens between the stapling machine and delivery so that the folded carrier can pass under the printed product without any problems, this also occurs in those Cases particularly useful when this printed product should be delayed in the ejecting operation.
  • the stapling machine itself, which is not shown in more detail and which belongs to the prior art, has a staple made of wire, the wire being bent in a first step to a U-shape that acts downwards, which is ideally suited to pushing through the brochure and to be bent afterwards.
  • This process is accomplished by at least one stapling head that cuts and positions the staple wire and forms it into a staple.
  • the stapling process itself involves pushing at least one staple through the brochure and closing it at the other end.

  • the stop 160 which is preferably operated by a servomotor 161, fulfills a multiple function with regard to the final positioning of the brochure 600, namely that this stop has a fixed stop position in relation to the transported brochure in the very last end state, but not exclusively in the conventional manner as a fixed stop station.
  • the stop in the final phase of the positioning of the brochure, there is a coordinated, control-guided interdependence between the horizontal transport movement of the brochure and its vertical transfer, with the stop then, as already explained, performing a double function, namely on the one hand to ensure the final position of the brochure and on the other hand possible tilting to be collected during the vertical conveyance out of the same. Accordingly, the stop also absorbs those counter-movements which could lead to a tilting moment for the brochure, which means that it can no longer be inclined.
  • These processes are in operative connection with a sword as part of an ejector arranged on the underside of the saddle chain, which will be discussed in more detail below.
  • Out Figure 2 shows the display 130 in operative connection with the motor-driven 161 stop 160 already explained.
  • This delivery is designed as a machine component that transfers the folded sheet, the brochure or the printed products in general to the product feed after the stapling station (see Figure 1 , Item 140) to the cutting device (see Figure 1 , Item 150).
  • the operating stop 160 basically defines the horizontal end position of the brochure with regard to the conveying out carried out by the display, the display being in operative connection with an ejector (see FIG Figure 4 ), whereby this position is always strictly oriented towards the fact that regardless of the small format size 202 resp. of the large format size 201 of the brochure, the conveyance always ensures a central ejection with respect to the operating aids of the display, that is to say the conveyor belts 131 arranged next to one another.
  • the Figure 3 shows essentially the same saddle stitcher as from Figure 1 .
  • This system is supplemented with essential control systems, the data of which are transmitted to a central controller 400, which in turn mutually communicates 401 with an MIS system 410.
  • This control processes all incoming data from all the units involved in processing the printed products, including the speed of the saddle chain 110, and then ensures the targeted control of all units, in particular the operation of the transport chain, stop, delivery, ejector, depending on the format size of the respective printed product.

The sword 503 is waiting here, which is coupled to an ejector plunger 502 and primarily forms the components of the ejector.
  • the ejector ram 502 preferably has its own drive, and When the "Trigger" command arrives, the motion kinematics are started.
  • the ejector 500 viewed as an overall unit, then starts its movement at the trigger position in order to generally transfer the printed product into the delivery as consistently as possible.
  • This "trigger" point is mainly dependent on the speed of the saddle 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 not reached.
  • the speed of the operative parts 502, 503 of the ejector 500 is directed towards that of the saddle chain or the conveyor belts belonging to the display. This means that if the speed of the saddle chain is increased, the ejector moves upwards faster. If the speed of the saddle chain is reduced, the ejector will certainly move more slowly.
