Definitions

  • the invention relates to a paper folding machine with a plurality of radially adjustable folding rollers, each forming a folding point in pairs, which are mounted in bearing arms with two-armed pivot levers which can be moved apart against the action of radial spring forces and whose second lever arms can be lifted off by actuators with which the center distances of the folding rollers can be raised
  • Self-locking, manually adjustable thread interventions can be set to different gap widths according to the paper thickness to be processed and the number of paper layers passing through the individual folding points, as well as with mechanical or electronic flow limiters, which precede the individual folding points and can be individually adjusted to different lead lengths.
  • the center distances of the folding roller pairs forming the individual folding points can only be adjusted manually after the user has previously known or determined them Paper thickness, and on the basis of the type of fold set by him, determined in how many layers of paper the folded material passes the individual folds.
  • Paper thickness and on the basis of the type of fold set by him, determined in how many layers of paper the folded material passes the individual folds.
  • all folding points which are traversed by a trailing single-layer section of folded material can only be set to the simple paper thickness, because otherwise the frictional drive required for folding this single-layer trailing section of folded material would no longer be guaranteed.
  • the invention is therefore based on the object in a paper folding machine of the generic type to facilitate the setting and / or determination of the gap widths of the individual folding points corresponding to a certain paper thickness, paper length and type of folding and to guarantee error-free paper transport through all the folding points and the greatest possible functional reliability shape.
  • a programmed process computer with an input keyboard and a digital display is provided for determining the gap widths of the individual folding roller pairs, and the thickness and the sheet length of the incoming folding material are either manually or via electronic analog-digital converters from a thickness measuring device or one Length measuring device as well as the desired fold type and / or the set lead lengths of the individual lead limiters are entered, and that the fold gap widths calculated by the process computer from the entered values are displayed as digital values and / or via a control device provided with electronic comparator circuits and power amplifier stages are supplied, which control the electric geared motors of overrun control devices, which cause the stepless adjustment of the individual center distances to the respective single or multiple thicknesses of the folded goods by means of the respective thread interventions and which have electrical or electronic position indicators as actual value transmitters, each with the Actuators are connected.
  • the linking or utilization of the individual parameters namely the paper thickness, the paper length and the paper layers resulting from the selected type of fold in the individual fold locations, is carried out in the process computer after a program has been entered, for example in an EPROM, that is to say in an erasable program command memory, and with the help of coincidence processes that are part of the program. It is also necessary to have electronic memories available for storing or temporarily storing the external values, which are integrated as usual in the process computer. With a suitable subroutine, the process computer is also able to determine from the entered paper length and the entered type of fold in how many layers the folded material passes the individual fold points and whether the same folded material first has two or more layers and a certain fold point then runs through with a trailing section only in one layer.
  • the flow limiters are usually designed as folding pockets with mechanically or electrically adjustable paper stops. But there are also upset folding machines in which non-stop flow limiters are provided with electronically preset flow lengths. In both cases, the settings of the individual lead lengths can be made available to the process computer as parameters in the form of digital values when determining the individual gap widths.
  • Compression folding machines with several pairs of folding rollers and folding pockets are also known, in which a process computer calculates the working positions of the paper stops and the paper deflectors by entering the initial format of the folding material, the final format of the folding material and the type of folding, and in which these values determined by the process computer for the continuous adjustment of the Paper stops can be used with the help of a tracking control device (DE 27 38 689 C3).
  • an electronic pulse generator which is synchronized with the folding rollers and is controlled by folding material sensors, is provided for the control of the flow limiter which can be actuated by means of electromagnets in accordance with the folding length.
  • This type of flow limiter works without a stop (DE 27 57 182 C2).
  • the electronic pulse generator and the folding goods sensors controlling them the leading distance of the leading folding material section is determined in principle, with the help of a coincidence circuit, the stop movement of the corresponding braking or locking elements is triggered.
  • the coincidence circuit can be set to the respective number of pulses by means of a keyboard or by a process computer, upon reaching which the flow limiters should come into action. In this respect, a length measurement also takes place.
  • the main advantage that is achieved with the invention is that even if the actual center spacing is set manually, a significant relief and, above all, a considerably higher level of safety is guaranteed when the actual center spacing is set manually because these values to be set in each case are made by the process computer determined and displayed. This means that this main advantage can also be achieved with relatively little effort. In addition, however, there is also the possibility of fully automatic programming of an upset folding machine for any desired folding work, taking into account the optimal folding gap widths at the individual folding points.
  • the adjustment mechanism provided according to the invention is of great advantage in particular in those cases in which the center distance of a pair of rollers must be set to a folding gap width which corresponds only to the simple paper thickness, although the folding point in question is passed through by the material to be folded in multiple layers.
  • it allows in a simple way to precisely set the desired folding gap width and nevertheless to realize a radially resilient mounting of the individual folding rollers, which only makes it possible for a folding point which is set to a folding gap width corresponding to the simple paper thickness to be multilayered folded goods can therefore be passed with the multiple paper thickness and still works reliably with optimal fold formation.
  • the embodiment according to claim 2 relates to an expedient arrangement of the thickness and length measuring device in a transport path, which is usually present anyway and is used for the longitudinal alignment of the folded material along a guide bar.

  • the folding roller W 1 forms with the folding roller W 2 the first folding point A
  • the second folding roller W 2 forms the second folding point B with the third folding roller W 3

  • the maximum adjustment paths or fold gap widths are of the order of 1 mm or less and the fold rollers usually have a diameter of about 35 to 40 mm or even more, the displacements occurring during the adjustment in the circumferential direction of the opposite roller do not affect the folding quality, provided, of course, that the parallel axis course is preserved.

Both paper deflectors 11 and 12 can each be actuated by electromagnets E 1 and E 2 so that they either close the inlet openings of the folding pockets T 1 and T 2 or keep them open.

  • the work program contains a mathematical arithmetic procedure that retraces the complete folding process taking place in the machine or executes it in advance. For example, the individual lead lengths are successively subtracted from the initial length of the paper sheet. Then it is checked how many layers of paper are created by this folding process. After the number of paper layers has been determined in this way, this can be multiplied by the parameter "paper thickness" and converted into the gap width for each pair of rollers.
