Definitions

  • the invention relates to a folder, in which the transport of the folded copies is carried out by means of transport, tape rolls and tapes.
  • the folded copies initially transported at high speeds in the folder must be braked for further processing, in particular for the second longitudinal fold formation, so that e.g. during the folding process no paper jam occurs.
  • Brush devices that act on the specimen or suction devices that apply a decelerating force to the specimen are known which serve to reduce the speed.
  • Slow-down cylinders are also used to reduce the speed in order to reduce the speed of the folded copy.
  • two deceleration cylinders which feed the fold copy to the second longitudinal fold formation, are arranged one behind the other.
  • the speed per cylinder is reduced by 30%.
  • Conveyor belt assemblies are also known which operate at fast and slow speeds. The folded copies are transported from the fast to the slow belts and picked up by them.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • the advantage of this solution is that the fold copies arriving on the first belt arrangement are not abruptly braked due to the variable speed during the transition from the first to the second belt arrangement, and that the fold copies are kept and guided continuously on the transport route.
  • Fig. 1 has such a folder with which an endless paper web previously printed in a printing press is folded.
  • This folder consists of the former (1) over which the printed paper web runs by forming a first longitudinal fold which is parallel to the edge strips of the paper extends, the two edges of the web width lying one above the other.
  • the web (8) thus folded passes through the funnel folding rollers for the purpose of forming the first longitudinal fold as well as through the pair of transverse perforating cylinders (2A, 2B) which perforate the web at the point at which the first transverse fold is later to be found.
  • the web then continues between the cutting cylinder (3) and the collecting or transfer cylinder (4).
  • the cutting cylinder (3) is provided with cutting knives (9A, 9B) which are arranged on the surface line of this cylinder and which cooperate with cutting knife counterparts which are provided on the collecting or transfer cylinder (4) around the longitudinally folded web (8 ) to cut.
  • Punctures (11A, 11B, 11C) hold the top of the specimen so cut by indenting near the leading edge of the specimen.
  • Folding knives (12A, 12B, 12C) guide the specimen with the center into the folding jaws (13A, 13B, 13C, 13D), which are provided on a folding jaw cylinder (5).
  • the decelerating cylinders (6A, 6B) alternately record the specimens that run successively over the cylinder (5).
  • the deceleration cylinder (6A) is provided with grippers (14A, 14B) and the deceleration cylinder (6B) with grippers (14A ', 14B').
  • These cylinders are called slowdown cylinders because they rotate at the same angular velocity as the cylinder (5); however, they have a smaller diameter, so that they consequently have a lower linear velocity.
  • the device is designed in such a way that the gripper (14B) of the upper decelerating cylinder grips the copy located in the folding flap (13D) and that the gripper (14A) the copy located in the folding flap (13B) on the first transverse fold edge detected.
  • the gripper (14A ') on the first transverse fold edge of the lower decelerating cylinder comprises the specimen located in the folding flap (13C) and the gripper (14B') the specimen located in the folding flap (13A).
  • These slowdown cylinders are followed by belts or belts running in parallel, which grasp the once folded copy and feed it to a device (7A) which works together with the slowdown cylinder (6A) and a device (7B) which works together with the slowdown cylinder (6B) .
  • a belt arrangement (15) consisting of four belts is provided below the copy coming from the cylinder.
  • the bands (16) (Fig. 2) are arranged above the specimen. This belt arrangement detaches the specimen from the deceleration cylinder (6A or 6B) and conveys it until it comes into contact with the stop (17), where it is stopped by sliding between the belts.
  • the stop (17) is comb-shaped; in its lower part it consists of four recesses (18) which allow the bands (15, 16) to pass freely.
  • Two folding rollers (21A, 21B), which - as shown in FIG. 3 - rotate in the opposite direction, are arranged under the folding table (19) opposite the gap (20).
  • the entire kinematic chain is designed in such a way that the folding knife (22) is in a lower position shortly after the arrival of a folding copy (27) on the stop (17).
  • rollers (21A, 21B) thus grasp the specimen and fold it perpendicular to the fold formed between the cylinders (4, 5). This second longitudinal fold is also called "sword fold".
  • Fig. 5 shows a possible division of the copies in such a folder.
  • Fig. 5a it can be seen how the paper web - cut but not folded - is wound around the collecting cylinder (4).
  • Each copy has a length C; and the distance between two successive specimens is also C.
  • Fig. 5b shows the copies lying on the cylinder (5) after the folding process. The distance between two copies is still C, but the length of each copy is only C / 2 after the copy has been folded in half.
  • Figure 5c shows the only non-hatched specimens on the deceleration cylinder (6A) prior to deceleration. The distance is now 2C and the copy length C / 2.
  • 5d shows the specimens transported to the deceleration cylinder (6A) after a deceleration of 25% (3/4 of the distance between two specimen spines remains). The distance is 6C / 4 and the copy length C / 2.
  • Figures 5e and 5f show the operations on the slowdown cylinder (6B), which are identical to those on the slowdown cylinder (6A), with respect to the hatched specimens of Figure 5b.
  • the distance between two consecutive copies in the usual second longitudinal fold must be at least C if the copy length is C / 2.
  • FIG. 6 shows a device according to the invention. Above all, a sequence of specimens can be seen, the specimen (27) between two belt arrangements, ie between the high-speed upper (28) and the high-speed lower belts (29) is clamped, these tapes wrapped around the deceleration cylinder having a peripheral speed which corresponds to that of the deceleration cylinder.
  • the copy (27 ') is also clamped between two slow belt arrangements (30, 31) rotating at half the machine speed, which transport the copy up to the stop of the sword fold.
  • the slow moving upper belt assemblies bear the reference number (30) and the slow moving lower belt assemblies the reference number (31).
  • a device consisting of a roller (33) which is mounted in an oscillating manner at the end of a lever (34) and whose longitudinal position is adjusted by means of an adjusting wheel (35) which is connected to a screw-nut connection (36). acts to set the position of the last gripping movement of a signature between the fast bands.
  • a device (33 ', 34', 35 ', 36') which is identical in all points makes it possible to adjust the position in which the gripping movement between the slow belts begins.
  • FIG. 7 is a top view of FIG. 6.
  • Fig. 7 it can be seen that the belts (31) are wrapped around guide rollers (43) which have a smaller diameter than the partially rubber-coated belt rollers (38) and which are movably mounted on the shaft (40).
  • the belts (30) are also wrapped around the guide rollers (42), which are movably supported on the shaft (39) between the partially rubber-coated belt rollers (37).
  • the shaft (39) is rotatably mounted on two levers (44, 44 ') which are articulated to the frame via a geometric axis (45).
  • Fig. 8 shows the entire drive with a cyclically variable speed.
  • This drive consists of the following components: an intermediate shaft (48) by the main control of the machine is driven via a roller (49) and a toothed belt (51).
  • the entire drive is designed such that the disk (52) which is arranged at the end of the shaft (48) makes one revolution each time the folder produces a copy (27).
  • the disk (52) drives an opposite disk 53) by means of a cam roller (54) which is fastened on the disk (52) and which runs in a guide groove (55) provided in the disk (53).
  • the disc (53) itself is connected to the output shaft (40) which carries a gearwheel (57) attached to it and which also drives the lower belt rollers (38), which are partially covered with rubber.
  • the gearwheel (57) is connected to a further gearwheel (58) which has the same diameter and is fastened on the shaft (39) by means of two small gearwheels (59, 60) located in between.
  • the gear drives the upper band rollers (37).
  • the device ensures the synchronous drive of the upper and lower belt rolls by allowing the setting of the pressure force between said upper and lower belt rolls.
  • the lower and upper partially rubber-coated tape rolls (37, 38) are fastened in such a way that the rubber-coated parts - which consequently have a larger diameter - are exactly in phase, i.e. the beginning and end of the rubber layer pass the connecting line of the center points ( 39, 40), namely that of the upper and lower band rolls at the same time, as a result of which the specimen (27) located between them is clamped or released at the same time.
  • Fig. 9 has a diagram in which two curves (70, 71) are shown.
  • the rotation angle A of -90 ° to + 360 ° of the drive shaft (48) of the device of FIG. 8 is plotted on the abscissa.
  • the rotation angle B of the output shaft (40) is plotted on the ordinate.
  • the curve (70) represents the exit angle as a function of the entry angle.
  • the curve (71), which is shown in the same diagram, is the derivative of the curve (70) and gives the relationship between the exit angle speed and the entry angle speed in all points of the device shown in FIG.
  • the curve (71) thus shows the change in circumferential speed of the belt rolls (37, 38), which are partially covered with rubber, as a function of their angular rotation.
  • the device works in the following way: A specimen (27) is pushed by the fast belts (28, 29) between the two partly rubber-coated belt rolls (37, 38) at the speed of the fast belts (see FIG. 9, straight line) 72). If this example exceeds the connecting line of the center points (39, 40) by a few centimeters, the partially coated rubber rolls (37, 38) come to the point during their rotational movement, at which these are covered with rubber and at this point the tape rolls reach their top speed.
  • the signature thus reaches the speed of these partially rubber-coated tape rolls, which corresponds to that of the fast tapes (straight line 72).
  • the adjusting wheels (35) on the fast and slow belts have the task of setting the exact point at which the belts capture or release the copy.
  • Fig. 10 has a folder according to the invention, which consists of two separate belt arrangements, the slowdown cylinders are subordinate.
  • This folder is suitable for the formation of an upper sword fold as well as a lower sword fold.
  • FIG. 11 Such a folder is shown in Fig. 11.
  • the specimen (27) is therefore taken directly from the folding jaw cylinder (5) by the fast belt arrangements.
  • the eccentricity between the shafts (40, 48) and the radius of rotation of the axis of the cam roller (54) around the shaft (48) are thus adjusted in order to reduce the speed of the partially coated rubber rollers by 50%.
  • the slow belts rotate half as fast as the fast belts.
  • a device is also conceivable with which folding copies of a variable folding apparatus - as used in gravure printing - or a completely different type of folding apparatus are slowed down.
