Process for slowing down printed products

The invention relates to a method for slowing down printed products on rotary printing machines, from which they are delivered as individual products at a distance from one another.

The object of the invention is the slowing of the print products, as it is for further processing, preferably in the folding apparatus, required when the Anliefergeschwindigkeit from a web-fed rotary printing machine, for _o example 14 m / sec exceeds above which previously known folding devices fail. The slowing down must be done without jerky loading for the printed copies, especially if these are sheet packs, since the cycle of the folding devices must be matched to the distance between the cut and then additionally accelerated printed products to gain distance.

According to the invention, the new slowing down method consists in that the product of one for its own Axis and cylinder rotated about another axis is recorded at a point at which the peripheral speeds of the two rotating movements in the same direction add to the delivery speed, and at one point is delivered, at which the peripheral speeds subtract from each other.

In the case of the invention, if the circumferential speed of the cylinder rotated about its own axis is, for example _{, the like}

the delivery speed of the product and the circumferential speed of the planetary system rotated around the other axis 25% of the delivery speed of the product, the sheet product can be taken over by the cylinder smoothly at a point at which the two circumferential speeds add up to 100%. The sheet pack now follows the cylinder and is thrown from it at a point at which the peripheral speed of the planetary system is subtracted by 25% from the peripheral speed of the cylinder by 75%. The sheet pack then arrives outside at 50% of the delivery speed. This is also done smoothly. It can now be further processed by conventional means, for example _o folded, be.

The new method can be carried out in a wide variety of ways.

An example of this is characterized in that the products on the outer rotation circle are delivered at delivery speed are picked up and delivered to the inner circle of rotation, whereby they are at a reduced speed arrive outside the system. This process requires particularly little technical effort. It leaves A deposit of the slowed product is only to the center of the system, where the further transport is only transverse to the deposit movement is possible, which requires a slowdown to zero and a stack-shaped or shingle-shaped display results.

Another embodiment of the new method is according to the invention that a pair of cylinders from which each cylinder is rotated around its own axis of rotation, is rotated around a further axis like a planet on a web, and that the reception of each product on the jacket of a first cylinder, which is in the direction of rotation of the planetary system around its own axis is rotated, takes place at an outer point at which the sum of the natural peripheral speed abwxüat and the peripheral speed of the planetary system corresponds to the full delivery speed of the product,

and wherein the second cylinder has the same circumferential speed as the first cylinder but in opposite directions Direction is rotated and the product is transferred from the first cylinder, which is transferred from the second Cylinder is released at a point of the rotation circle of the planetary system against the direction of rotation of the same, the product arriving outside the system at a reduced rate. The filing with the reduced speed run parallel to the delivery with the high speed, the arrival speed at the deposit of the further processing speed which can be safely mastered with conventional means.

According to a further variant of the invention, it is possible that several pairs of cylinders with one another invariable Distances like a planet are rotated on a web about a common further axis. This execution opens up the possibility of skipping the loading cycle of the plurality of cylinder pairs in use, so that even with short - equal to one another - distances between the individual products in the delivery flow, each cylinder pair has enough time to slow down in the planetary system and separates the shelf into at least two different paths where the further processing stations are provided in duplicate.

The same can be achieved according to a further proposal of the invention in that two pairs of cylinders are planetary are rotated around their own additional axis, whereby the circles of rotation of their planetary systems touch each other, the contact point of which the individual cylinders alternate due to the angularity of the two planetary system webs reach.

The method according to the invention makes it possible that the planet-like rotating cylinder pairs on their inner

In Fig. 1, the product 1 delivered at high speed ν, z “B” a printed sheet pack is taken over at an outer point 6 by the cylinder jacket of a first cylinder 2 of a cylinder pair 2, 3, each of which is rotated about its axis _o both axes are connected to one another by means of webs 5 and are rotated about a further axis 4 like a planet on them. Both cylinders 2, 3 are arranged to each other so that their shells touch each other and the common rotation circle 8 tangentially = the direction of rotation D of the cylinder 2 and the direction of rotation P of the web 5 are clockwise. The delivered copy 1 is taken over smoothly at 6, where the peripheral speed of the cylinder 2 and the peripheral speed of the planetary system add up to the full speed ν because of the same direction of rotation. Between the cylinders 2 and 3, the product 1 is transferred to the second cylinder 3, which has the same circumferential speed as the cylinder 2, but in the opposite direction R.

rotated o In the outer area of the circle of rotation 8 at 7, the product 1 is delivered at the circumferential speed of the cylinder 3 counter to the direction of rotation P of the planetary system, by whose circumferential speed the product speed is reduced. If the circumferential speed of cylinders 2 and 3 is 75 ⁰ A eier delivery speed V ₀ and that of the planetary system with the web 5 25 $, then the discard speed ν _χ = 75-25 = 50/0 of v _qO

In FIG. 2, several pairs of cylinders 12, 13, the cylinders of which are rotated about their axes in direction D and R, as in FIG will. Here, too, the printed copy 11 is ^{fed to the cylinder 12 in the manner already described in ZuI 1} Ig ₀ 1 and delivered by the cylinder 13 in the direction of rotation R, which is opposite to the direction of rotation P, so that it arrives outside the device at a reduced speed ν .

In the embodiment according to FIG »3, two pairs of cylinders 22, 23 and 22 ', 23', the individual cylinder in the direction D and R respectively ₀ D 'and R ¹ are rotated, also in as webs effective discs 25, 25' mounted rotatably and are rotated like a planet around their own further axis 24, 24 '. Their outer circles of rotation 28, 28 'touch one another. The individual cylinders reach this contact because of the angular offset of the lines connecting the axes of the cylinders of a pair by 90 ° one after the other. The printed copy 21 delivered with the speed ν is therefore alternately taken over by the cylinders 22 and 22 'between the two planetary systems, transferred to the cylinders 23 and 23' and ηηεϊοχεχηεχ from these against the direction of rotation P, P ^! of the planetary systems 25, 25 'delivered, with it arriving outside at a reduced speed ν.
