Definitions

  • the present invention relates to apparatus for braking and overlapping of sheets made of paper, cardboard or the like material to be deposited upon a stack, said sheets being ejected from sheet-producing machines, for example, transverse or cross.
  • the braking is done is such manner in known fashion that the sheets leaving the transverse cutter apparatus first are accelerated until they reach a spatial distance between the individual sheets, and that thereafter they are delayed again in such manner that a slow and disturbance-free stacking of the sheets can take place.
  • the deposit speed must be substantially less than the ejection speed of the machine, or in other words the sheets must be brought to overlap, with the extent of overlapping being determined by the advancing speed of the conveyor belts.
  • the reduction of the advancing speed of the sheets takes place such that several conveyor installations are arranged successively of which each successive one operates at a lower speed than the immediately preceding one.
  • suction air which, relative to the direction of movement of the sheet, exerts a braking effect on the rearward end with the result that the forward area of the following sheet slides over the rear area of the preceding sheet and thus initiates overlapping.
  • the effective upper side of the suction brake device is positioned somewhat lower than the preceding conveyor belt section so that by virtue of this slight difference in height, a disturbance-free overlapping is ensured.
  • the limitation of the braking effect upon the rearward sheet end is of particular significance since, as a result thereof, the sheet is stretched, likewise avoiding crumbling or bulging of the sheet which would otherwise occur if a braking effect is exerted upon the end of the sheet which is disposed forwardly as regards the direction of advance.
  • the present invention has for an object to provide a suction brake installation which is characterized by low expenditure, achieving a periodic braking effect and which, whem compared with the known types of embodiments moreover possesses the advantage of being quickly and easily controllable.
  • the arrangement is such that the perforated control belt is movable guided between the perforated suction chamber and a perforated cover plate so as to coincide with such suction chamber.
  • the movable control belt can be an endlessly revolving perforate belt, or the movable control belt can be formed by a perforate belt reciprocating in rhythm with the sheet sequence.
  • a further characteristic of the inventive installation is that the movements of the perforate belt are controlled in dependency upon the sheet sequence. This measure assures that, independent of the advancing speed of the sheets and independent of their format, the suction air acts upon a sheet rhythmically only in the rear zone of said sheet.
  • the efi'ective through-flow cross-section of the perforations of the suction brake installation is adjusted to the machine speed, that is to say that the cross-sections are enlarged with increasing speed.
  • the change of the through-flow cross-section can be achieved such that the aligned parts of the suction brake installation are displaced laterally.
  • Another way is provided by a likewise perforated adjustable slide member which is adjustably disposed between the suction chamber and the cover plate.
  • FIG. 1 shows in schematic representation a side elevational view of a suction brake installation built into a conveyor installation'
  • FIG. 2 is a cross-sectional view taken along line 2-2 of FIG. 1;
  • FIG. 3 is a perspective view of the suction brake installation
  • FIGS. 4 to 6 are enlarged fragmentary cross-sectional views through the suction perforations illustrating various phases of the suction process.
  • FIG. 7 is a fragmentary cross-sectional view of DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
  • the sheets 1 produced by a not-shown transverse or cross cutter installation are fed by conveyor belts 2 into the operative zone of the suction brake installation described infra in greater detail, and they then reach conveyor belts 3 after having been braked and overlapped, said conveyor belts 3 depositing sheets 1 on a stack, not shown.
  • the suction brake installation consists essentially of suction box or chamber 4 which is connected to a not-shown sub-atmospheric pressure producer via pipe extension 5.
  • the upper side or top of suction box or chamber 4 is provided with perforations 6 which are distributed suitably at the same spatial distance over the entire extension of the suction chamber.
  • a perforated cover plate 7 which essentially fills up the intermediate space between conveyor belts 2 and 3. Perforations 8 of cover plate 7 are aligned with perforations 6 of suction chamber 4.
  • a control belt 9 which is movable in the rhythm of the sheet sequence.
  • said control belt 9 is constructed as a thin endless belt enclosing suction chamber 4. The size and arrangement of perforations 10 in control belt 9 correspond to perforations 6 and 8 of suction chamber 4 and cover plate 7 respectively.
  • FIGS. 2 and 3 show that the perforated control belt is guided around drive pulleys 11 which are secured to shafts I2.
  • Followers 13 engage with perforations 10 of control belt 9 and assure a non-slip drive.
  • the revolving movement of control belt 9 is controlled in dependency upon the sheet sequence, that is to say upon the advancing speed and the length of the sheets.
  • one utilizes suitably a thin perforated belt which is adjustable transversely to the advance direction of sheets I. At one end of this perforated belt, there engages a draw spring 16 and on its other end a threaded spindle 17 permitting the desired adjustment, see FIG. 7.
  • FIG. 7 there is provided a likewise perforated reciprocating control belt 18 instead of the revolving control belt.
  • the reciprocating movements of said control belt [8 open and close the perforations 6, 8 add 10 of the suction brake installation in the rhythm of the sheet sequence.
  • the reciprocating control belt is driven with the aid of magnets I9 and 20 which are operated alternatively in dependency upon the sheet sequence. Accordingly;
  • Apparatus for braking the advance of and effecting overlapping of sheets of paper, cardboard or the like material comprising:
  • suction brake means arranged below the path of movement of said sheets for periodically applying suctions acting on the rear ends of successive sheets including:
  • a suction chamber having a perforated top
  • a cover plate between the top of said suction chamber and the path of movement of said sheets having perforations therein arranged in alignment with the perforations in said top;
  • control belt means for moving said control belt means lateral to said path of movement and in accordance with the rhythm of the sheet sequence to align the perforations in the control belt means with the perforations in the top of said suction chamber and the perforations in said cover plate.
  • Apparatus as claimed in claim 1 which includes perforated slide means laterally adjustable to said path of movement between said cover plate and said control belt means for adjusting the effective through flow cross-section of the per forations in said suction brake means.
