Definitions

  • the present invention finds in Kombifalzmaschinen that u. a. working according to the knife folding principle, application in which flat materials are folded between rotating rolls. It relates in particular to the folding blade drive of a folding machine with a linear drive, via which a guided in linear guides folding blade is driven.
  • a device for driving a folding blade in a folding apparatus of a rotary printing press in which four magnetizable coil heads are provided, which generate the vertical up and down movement of the folding blade.
  • the disadvantage here are the large height, the problems of uniform control of the coil heads and the Problems to realize a jam-free guidance of the folding blade with exact alignment of the knife edge to the folding rollers.
  • a folding blade drive which comprises a linear motor, on the rotor of a folding blade is attached.
  • the disadvantage of this is that the folding blade is not performed with the necessary accuracy and can jam when hitting the surface of the material to be folded, resulting in quality losses. Due to the central force necessary as central arrangement of the linear motor on the folding blade, which extends perpendicular to the longitudinal axis, resulting in a folding machine equipped with the folding mechanism total of an approximately T-shaped construction. This is due to the need to arrange several folders in a confined space, for example, compared with an L-shaped design, disadvantageous.
  • the solution for a folding blade drive shown in DE0010205550C1 likewise comprises a linear motor which, in order to realize a small structural size, is in particular transverse in height, ie. is arranged with parallel to the longitudinal axis of the folding blade extending working axis.
  • a 90 ° force deflection is realized by the linear motor rotor on the folding blade.
  • This configuration of the folding blade drive has the disadvantage of low accessibility of the drive parts linear motor and folding blade by their parallel arrangement, along with the resulting thermal problems at high dynamics of the folding blade drive.
  • the invention has for its object to provide a simply constructed folding blade drive for a folding machine, which allows a space-saving arrangement, especially in a multiple folders folding machine at the same time good accessibility and the precision and ideal shape of the blade insertion movement in particular guaranteed for long knife lengths.
  • the folding blade drive has a linear drive, via which a guided in linear guides folding blade is driven in a drive direction, the linear drive is disposed at one end of the folding blade and comprises a driven member whose axis of movement extends in the drive direction and at least one over rotatably mounted deflection running, provided at two points with the folding blade drive element, with which the movement of the directly or via the drive element connected to the one end of the folding blade output member is transferable to the other end of the folding blade.
  • the folding blade drive has a total of a simple construction.
  • the linear drive comprises an output member which is designed as a region-wise linearly guided, rotationally driven belt.
  • each drive is understood which has an output member which performs a linear drive movement, Is a linear motor provided as a linear drive, the movement of the folding blade can be optimized by appropriate control of the linear motor, without the need for additional transmission elements.
  • the linear drive is associated with one of the ends of the folding blade, it forms together with the folding blade approximately an L-shaped assembly that can be arranged alone or together with other similar assemblies space-saving.
  • the linear drive is associated with one of the ends of the folding blade, it forms together with the folding blade approximately an L-shaped assembly that can be arranged alone or together with other similar assemblies space-saving.
  • a belt or a toothed belt can be used, which runs on pulleys, pulleys or support rollers and is connected at two points with the folding blade.
  • a drive element may be provided as a drive element, a spring steel strip or a fiber-reinforced webbing. These are also subject to no or only a very small change in length in the direction of power transmission, which has a favorable effect on the power transmission behavior.
  • the spring steel bands and the fiber reinforced straps have a rectangular cross-section with low height.
  • the folding blade drive comprises a total of 4 deflecting elements over which a drive element runs in the form of an endless belt.
  • deflecting elements two are arranged in alignment with one another in the drive direction at each end of the folding blade. This results in the circulation of the drive element a total of four each lying between 2 deflecting sections (dreams).
  • Two of the strands extend in the drive direction of the folding blade, which is connected in the region of these strands with the drive element.
  • the two other dreams run crossed to each other, whereby a rectified movement of the drive element in the Areas is reached in which this is connected to the folding blade.
  • the two ends of the folding blade are thus connected with respect to their sequence of movements in a simple manner and a movement initiated at one end of the folding blade movement is linearly transmitted to the other Falzmesserende.
  • the drive movement generated by the output member of the linear drive can be initiated both directly and indirectly via the drive element at one end of the folding blade.
  • the folding blade thus experiences a synchronous to the output member movement and it is ensured that the folding blade can be performed by advantageously in the vicinity of its two blade ends mounted extremely short linear guides without jamming.
  • the elements used for power transmission have a low intrinsic mass, which also applies to the folding blade itself, which may consist of Maseredukom of fiber-reinforced plastics and may be additionally provided with recesses.
  • the folding blade By symmetrical application of force to the folding blade, which is realized at preferably two points in the folding blade longitudinal direction, its longitudinal stiffness required for the precise folding operation can be realized with a lesser mass.
  • the linear drive must apply only small forces in order to realize the folding blade movement with great accuracy according to the desired ideal location-time function.
  • Additional damping elements or elements that support the reversal of motion at the dead centers of Falzmesserhubes thus can be used without any impact on vibrational excitation. This is all the more true when a part of these elements is arranged to act on the driven member while the other part of the elements acts on the folding blade. In addition to minimizing the vibration excitation and the noise, a high service life of the damping elements is given.
  • the folding blade drive shown in FIG. 1 is part of a knife folding mechanism in which sheets fed in the sheet plane 2 by a conveying system, not shown, are folded from a pair of rotating rolls arranged below the sheet plane 2.
  • the folding blade 1 presses the sheets in the gap formed between the rollers until they are detected by the rollers.
  • the folding blade 1 moves in a perpendicular to the sheet plane 2 extending drive direction between two end positions back and forth.
