Definitions

  • the invention relates to a longitudinal folding apparatus with a braking distance according to the preamble of claim 1.
  • Such longitudinal folders are used in the printing industry, especially in the final production of printed products, the printed products are pressed by the folding blade in the folding gap and folded in this longitudinally. Because the direction of entry of the printed products into the longitudinal folder is transverse to their subsequent movement through the nip, they must be decelerated before passing through the nip.
  • Lijnsfalzapparaten brake brushes which gradually decelerate the incoming printed products by friction, and fixed stops are known, against which the printed products abut and thereby abruptly decelerated.
  • the friction between printed products and brushes also depends on the Surface texture of the printed products. Smooth paper products can hit the fence too quickly, while equally thick and equally heavy products made from a rough paper may not reach the fence.
  • the GB 1 326 891 discloses a longitudinal folder with circumferential bands provided with stops to decelerate a product to be folded.
  • the invention has for its object to provide a longitudinal folder with a braking distance.
  • the achievable with the present invention consist in particular in that the longitudinal folder is caused by the movable stop a gentle deceleration of the products, eg. B. printed products is achieved because the kinetic energy with which the products encounter the current stop, compared to the kinetic energy that is set free in the impact against a fixed stop, is reduced. If the difference between the input speed of the products and the speed of the current stop is chosen to be sufficiently small, the said unwanted effects due to a released kinetic energy can even be completely avoided. In this case, the movable stop can also absorb very high input speeds of the products and gently slow down the products. With the movable stop independent of mass, thickness and surface finish of the incoming products braking effect can be achieved, so that different products can be processed without the Lssensfalzapparat would have to be adjusted to this before.
  • the longitudinal folder comprises a control unit which controls a reduction in the speed of the stop on the braking distance.
  • the control unit targeted braking of the incoming products is possible so that they come to a predetermined certain position to a standstill and are optimally aligned for the subsequent folding, or that they are on a second, fixed stop, the desired position of the products for determines the subsequent folding operation, impinging at a low speed, at which no damage of the products is to be expected by the impact.
  • the speed of the stop can be changed via the control unit easily adjust the input speeds of the products.
  • a sensor for detecting incoming products is upstream of the braking path and coupled to the control unit, so that the control unit can synchronize the movement of the movable stop so that a detected incoming product hits at the beginning of the braking distance to the stop moving at approximately the input speed.
  • the speed of the stop at the beginning of the braking distance may be less than the input speed, as long as the difference between the speeds is not so great that damage to the product seems possible. It can also be slightly larger; in this case, it comes only later on the braking distance when the stop has become slower than the product, the contact between the two.
  • the stop is arranged in an advantageous embodiment on a running endless belt having a portion parallel to the braking distance.
  • the endless belt can either be provided as a retrofit module of the longitudinal folding apparatus via a folding table having the folding gap, or else the endless belt is arranged as a module permanently integrated in the longitudinal folding apparatus below the folding table.
  • the endless belt is a toothed belt on which the stopper is welded.
  • the stop is formed in a second advantageous embodiment as a circumferential cam whose direction of movement crosses a braking distance of the product at least on a path section.
  • a on a rotatable body, z As a disc, a roller or an eccentric, arranged circumferential cam, the stop in a continuous movement, without reversing the drive direction of one end of the braking distance - ie an external contact with the product - back to its beginning - ie a MixWallet - be transported to catch the next product there can.
  • the rotatable body can be provided either as a retrofit module of the longitudinal folding apparatus via a folding gap having the folding gap, or else the rotatable body having the cam is arranged as a module permanently integrated in the longitudinal folding apparatus below the folding table.
  • the body is a plurality of disks arranged axially next to one another and each having at least one cam on its circumference.
  • At least one endless belt is arranged, each carrying synchronously moving stops. Preference is given in each case two endless belts per side of the folding gap.
  • This engine is an electric motor.
  • a single motor by means of a continuous shaft drives the endless belts on both sides of the folding gap.
  • a velocity of the stop at the beginning of the braking distance of at least 90% of the input speed of the products, because then between the speed of the stop and the input speed is a sufficiently small difference, so that when the impact of the products to the stop little kinetic energy is released ,
  • the Fig. 1 and 2 show a longitudinal folding apparatus 01, in particular in a web-fed rotary printing press, once from a lateral view ( Fig. 1 ) and once in plan view ( Fig. 2 ).
  • At least one transverse folding device eg with a folding blade cylinder and a folding jaw cylinder
  • at least one longitudinal folding hopper is preferably arranged upstream of the longitudinal folding apparatus 01.
  • the longitudinal folding apparatus 01 comprises a folding table 04, in which an elongate folding gap 06 is provided. Under the folding table 04 is at the level of the folding gap 06, a pair of collapsed folding rollers 07, of which in Fig.

  • the distance between the surface of the folding table 04 and the strands of the two toothed belts 12 is slightly smaller than the height of the cams 13, 14.
  • the motor 16 is driven by a control unit 19, which is further connected to a sensor 18.

  • the control unit 19 continuously slows down the toothed belts 12 until the printed product 02 reaches the brake brushes 09 and is further decelerated by them and finally abuts against the stop 08 at a speed v at which it is not damaged by the impact.
  • the Fig. 3c) shows the situation shortly before the abutment of the printed product 02 to the stop 08, the Fig. 3 d) the situation shortly after the abutment of the printed product 02 to the stop 08. Since the printed matter 02 in Fig. 3c) is slowed down by the brake brush 09, the cams 14 have detached from the printed product 02. At the same time, the toothed belt 12 is accelerated again so that the second cams 13 are in time for the arrival of a subsequent printed product 02 at the entrance of the braking path 24 and have a speed v suitable for braking this printed product 02.
  • the brake brush 09 can be omitted.
  • the cams 13; 14 are slowed down when passing stop 08 to a lower speed v as if the brake brushes 09 are present to prevent damage to the printed matter 02 at the stop 08 and rebounding. It is therefore a more powerful engine 16 needed.
  • the now stationary printed product 02 is pressed by the folding blade 03 in a known manner through the folding gap 06 in the gap between the two folding rollers 07 and thereby folded longitudinally.
  • This is a well-known process, so that it will not be discussed in detail here at this point.
  • the Fig. 4 shows by way of example the time evolution (t) of the speed v of a printed product 02 when passing through the braking path 24.
