Definitions

  • the invention relates primarily to a method for changing the conveying speed of individual sheet-like structures or the like which are brought up on a first belt conveyor or the like, in particular printed products, by means of a second belt conveyor or the like and a third at different speeds driven belt conveyor or the like and a pressurization of the fabrics or the like which is carried out substantially perpendicular to the surface of the second belt conveyor.
  • a corresponding method is known from EP-A-0 075 121.
  • a delay device consisting of a vacuum chamber, which has the third endless belt conveyor; the latter is driven at a speed which is half the conveying speed of the second belt conveyor.
  • the third belt conveyor is perforated and runs over the delay device connected to a vacuum pump.
  • the invention is therefore based on the object of providing a method with which the possible dandruff errors can reappear in the same size in the event of a subsequent scaling.
  • the object is achieved in that, according to the invention, the introduction by the first belt conveyor or the like and the pressurization of the fabrics or the like with mechanical pressure exerted by the third belt conveyor on the same rhythm as the upstream depositing device of the fabrics or the like. regardless of the position d f leading edge of the respective sheetlike structure or the like and that the mechanical pressure from the third to the second belt conveyor is maintained by a linear parallel guidance over a section of the conveying path of the sheetlike structure or the like.
  • the flat structures or the like are pulled apart until they are completely separated.
  • a device which has a first belt conveyor or the like for guiding the flat structures or the like, a second and a third belt conveyor driven with different speeds in relation to the latter and means for exerting pressure on the flat structures o. Like.
  • the means for exerting the mechanical pressure consist of at least three, preferably five rollers, rollers or the like, which are resiliently attached to a star, the tangential speed of which is the same as the tangential speed of an upstream delivery device for the fabrics o Vietnamese agrees and that the third belt conveyor has at least one deflection roller or roller, which brings about a straight parallel guidance.
  • the third belt conveyor or the like can be designed as an endless conveyor.
  • rollers, rollers or the like of the star are also designed as deflection rollers, rollers or the like of the third belt conveyor or the like.
  • Each roller, roller or the like of the star can be individually resiliently mounted in the radial direction.
  • the rollers, rollers or the like of the star in the region of the second belt conveyor or the like are positively guided parallel to the latter;
  • the positive guidance can consist of at least one cam disk or the like arranged on one side of the second belt conveyor or the like.
  • the products delivered by a web-fed rotary printing press can be folded signatures, single sheets or even stacks of sheets, provided that they are in the form of a scale with the usual means of conveyance, e.g. B. pairs of endless conveyor belts can be conveyed at high speed.
  • Web-fed rotary printing presses in which folds are also made, deliver e.g. B. 40,000 signatures per hour in scale form.
  • the device described below is intended to ensure that the error present in each case is kept constant.
  • the paper products are introduced via a first belt conveyor (not shown) of the device according to the invention.
  • the slightly elastic endless belt of the belt conveyor 5 is approximately 50-55 cm wide in the embodiment shown and has an adhesive surface. Instead of the single wide belt, a number of narrower belts can run over the deflection rollers.
  • a star rotating around an axis 10 Arranged within the endless belt of the belt conveyor 5 is a star rotating around an axis 10, which has free-running rollers 11 - five rollers are provided in the present case.
  • the star provided with the five free-running deflection rollers engages with two or three deflection rollers on the inside of the belt conveyor 5.
  • the individual rollers 11 of the star are attached to a housing 13, each provided with a spring 12, so that they can spring in the radial direction.
  • straight sections of the belt conveyor 5 are provided from the free-running roller 14 to the corresponding free-running deflection roller 15 and again to the corresponding deflection roller 16.
  • the straight section of the endless conveyor to the shed entry point. 20 has an acute angle to the horizontal in order to precisely determine the line of contact between the two endless belts of the second belt conveyor 3 and the third belt conveyor 5.
  • the respective freely running rollers 11, 14, 15 and 16 and 17 together form an arc angle which is adapted to the paper product distance.
  • the third belt conveyor 5 is driven at a triple speed of 150 m / min in order to pull the paper product flow apart.
  • a cam disk 30 is provided on each side of the two belt conveyors 3 and 5, which determine the running of the laterally projecting, free-running rollers 11 and 14 to 17, respectively.
  • rollers in the upper part of their rotational range rotate in the fully extended position due to the spring load, they are pressed inward by the charging surface 31 in the cam plate 30 in the lower third against the action of the springs 12, the respective paper product being detected at the point of curvature 32 .
  • the belt conveyor 5 is released from the paper product and runs over the deflection rollers 6, 7, 8, whereupon the next paper product is detected in the entry point 20.
  • the star can with five deflection rollers and the belt conveyor 5 z. B. be provided with four deflection rollers; However, it is not necessary that the deflecting rollers of the star on the third belt conveyor 5 - as stated above - attack with at least two rollers, but only one deflecting roller of the star is then necessary for the pressing.
  • a second star with a belt conveyor can also be used.
