Definitions

  • the invention relates to a device for braking printed products in the delivery paddle wheel of a folder.
  • US Pat. No. 4,600,186 shows a rotating cam disk provided with three cams, which is arranged within the envelope curve of a paddle wheel. When gripping the rear ends of the printed products, the cams also interact with rotating rings.
  • a common feature of the devices disclosed in the two patents mentioned is an abrupt, sudden onset of the braking process when gripping the rear ends of the printed products. This can cause problems, especially with thicker printed products. Both known devices are intricately driven by rollers and rings each interacting with the cam disks, which are also difficult to adjust.
  • the device according to the invention for braking printed products in the delivery paddle wheel of a folder which has the following features: On a drive shaft, a plurality of impeller disks are arranged side by side, which have a plurality of impeller blades and impeller wheel pockets formed between them; a number of brake rollers corresponding to the number of paddlewheel disks is provided on a driven brake shaft mounted parallel to the drive shaft; the brake shaft is optionally driven in one of two directions of rotation via the drive shaft, and the brake rollers and front edges of the airfoil act together to delay the movement of a printed product entering a respective airbag.
  • the advantages of the solution according to the invention can be seen in the fact that in a device for braking printed products, the number of pockets in the paddle wheel can be increased without having to accept a loss in braking efficiency. This allows higher productivity. Furthermore, the sudden braking of the printed products at their rear end has been eliminated and the mechanical stress on the printed products is reduced. The risk of greasing in the braking area at the rear end of the printed product is also reduced. Furthermore, additional brake elements to be driven, such as rings or rollers, can be dispensed with, since the joint movement of the front edge of the airfoils and the circumferential surfaces of the brake rollers is used for braking, and a harmonious deceleration can thus be achieved. Another embodiment of the invention provides that opposing brush segments are attached to the brake rollers.
  • At least one ring which can be mounted on the brake shaft and is provided on the circumference of the ring and is situated opposite and opposite elastic linings of varying thickness in the circumferential direction. It is also possible to mount linings on the rings that can be mounted on the brake shaft that have a coefficient of friction that varies over the respective lining length.
  • an axle is provided on the driven brake shaft and arms for the displaceable attachment of shaft bearings for mounting the brake shaft on the axle, the arms for guiding the displaceable shaft bearings being provided with elongated holes.
  • the shaft bearings have a brake shaft and a Take up another shaft, each having a pulley and a gear at their drive ends. This offers various drive options.
  • the drive for the brake shaft comprises a first pulley mounted on the drive shaft, a second pulley mounted on the brake shaft and a drive belt guided around the first and second pulleys for directly driving the brake shaft against the direction of rotation of the drive shaft.
  • the drive for the brake shaft comprises a pulley mounted on the drive shaft, a further shaft mounted on the brake shaft, respective gear wheels mounted on the brake shaft and the further shaft, a pulley mounted on the further shaft and one around the pulley drive belt guided on the drive shaft and the pulley on the further shaft for driving the brake shaft in the same direction as that of the drive shaft.
  • a belt tensioning roller for tensioning the drive belt is provided for driving the brake shaft.
  • the drive of the brake shaft comprises a first pulley mounted on the drive shaft and a second one mounted on the brake shaft Pulley and a third pulley mounted on the further shaft mounted on the brake shaft, respective meshing gears mounted on the brake shaft and the further shaft, and a drive belt which are alternately guided around one of the second and third pulleys and around the first pulley can to drive the brake shaft against the direction of rotation of the drive shaft and in the same direction of rotation as that of the drive shaft.
  • Fig. 1 shows a plan view of the paddle wheel disks, the brake rollers and the belt drive of the device according to the invention.
  • a paddle wheel arrangement 2 which consists of a plurality of paddle wheel disks 2a, 2b and 2c.
  • a pulley 3 for driving the brake shaft 11 is provided on the drive shaft 1.
  • the drive belt 21 rotating on the belt pulleys 3 and 5, indicated in FIGS. 4a to d, is tensioned by a belt tensioning roller 4 mounted on a belt tensioner 6.
  • the pulley 5 is attached to a brake shaft 11 which is received by two shaft bearings 12 and 13.
  • the shaft bearing 12 has a double ball bearing for the drive end of the brake shaft 11, while the other end of the brake shaft 11 is received by a simple ball bearing in the shaft bearing 13.
  • the brake shaft 11 can rotate in a ratio of 5: 1 to the drive shaft 1. This ensures that brake rollers 18, which carry two brush segments 19a and 19b (see FIG. 3b), act on the rear end of each printed product 30 which enters one of the ten paddle wheel pockets 22 provided here, for example (see FIGS. 2 and 4a to 4d).
  • brake rollers 18, which carry two brush segments 19a and 19b see FIG. 3b
  • the belt tensioner 6 is also mounted on an axis 14.
  • the belt tensioner 6 has a tensioning lever 7 with two roller bearings 8, in which a short shaft 9 is supported, which carries the belt tensioning roller 4.
  • the shaft bearings 12 and 13 attached to the axis 14 can e.g. B. in the shaped in support arms elongated holes 16 and 17 both in the direction of the paddle wheel discs 2a, 2b and 2c as well as away from these.
  • the two shaft bearings 12 and 13 are connected to each other by a cross member 15, which is screwed twice in each of the shaft bearings 12 and 13.
  • a plurality of brake rollers 18 are mounted on the brake shaft 11, each of which is assigned to one of the paddle wheel disks 2a, 2b and 2c.
  • the brake rollers 18 have brushes 19 on their peripheral surfaces.
  • a pulley 5 and a gear 34 are mounted on the brake shaft 11, on the further shaft 35 there are also a pulley 5a and a gear 33; this provides various drive options with regard to the direction of rotation of the brake rollers 18 (see FIG. 2).
  • a bucket wheel arrangement 2 consists of a plurality of bucket wheel disks 2a, 2b and 2c fastened on the drive shaft 1 (FIG. 1).
  • the paddlewheel disks each consist of paddle blades 20 which - with respect to the direction of rotation of the paddlewheel disks - have a respective front edge 20a and rear edge 20b.
  • Paddle wheel pockets 22 are formed between the individual blades 20 - in the exemplary embodiment shown there are 10 in number.
  • the printed products 30 to be conveyed by the bucket wheel arrangement 2 are guided into the bucket wheel pockets 22 of the bucket wheel arrangement 2 by conveyor belts 23 which rotate on deflection rollers 24.
  • the supply of the printed products is timed so that a printed product 30 released by the conveyor belts 23 enters a paddle wheel pocket 22 when the latter is located opposite the discharge opening between the individual conveyor belts 23. After entry of the front end of the printed product into the bucket wheel pocket 22, it slides along the front edge 20a of the respective bucket blade 20 onto the bottom of the bucket wheel pocket.
  • the brake roller 18 is provided with two brush segments 19a and 19b which rotate in the direction of rotation indicated by an arrow shown in FIG. 4a. Accordingly, in the example shown in FIG. 2, the brush segment 19b approaches the front edge 20a of the airfoil 20 and detects an abutting rear end of a printed product 30. Since the brush segments are elastic, the braking force is built up successively up to a maximum value when the Bristles of the brush segments 19a and 19b are strongly bent. On the other hand, the airfoil end 20c moves along the envelope curve shown in FIG. 2 towards the brush segment 19b and thereby increases the braking effect.
  • the drive configuration shown in FIGS. 4a-4d also runs from the pulley 3 via the belt tensioning roller 4, then via a further pulley 5a seated on a shaft 35 and back to the pulley 3.
  • a gearwheel fastened on the shaft 35 behind the pulley 5a 33 meshes with a gear wheel 34 fastened on the brake shaft 11, which sets the brake shaft 11 in rotation in the direction of rotation shown in FIG. 4a. If the brake rollers 18 are to move in the opposite direction to the direction of rotation of the paddle wheel disks 2a, 2b and 2c, the drive belt 21 is moved from the belt pulley 3 via a belt pulley 5, the belt tensioner 6 assuming the position indicated by the broken line in FIG. 2.
  • Both the belt tensioner 6 and the shaft bearing 12, e.g. 1, are mounted on an axis 14 which can be moved by an actuating device 29.
  • the delivery table 32 can be adjusted in height by an adjusting cylinder 25.
  • the tensioning lever 7 is fastened to the axle 14 with two clamping screws 26.
  • Fig. 3 versions of the brake rollers 18 are shown. Both brush segments 19a and 19b and pads made of elastic, resilient material can be attached to the brake rollers 18.
  • the thickness of such linings 28a, 28b can vary in such a way that a continuously increasing deceleration can be achieved, as shown in FIG. 3.
  • spring-mounted projections are also conceivable, the flexibility of which can be varied by the combination of disc springs and / or spiral springs.
  • projections which can be acted upon by a damping medium and which allow progressive braking force to be exerted.
  • foamed plastics can be used as brake pads.
  • FIG. 4a the position of the airfoil 20 is labeled "0 °”.
  • a printed product 30 has entered the paddle wheel pocket 22. Its rear end lies against the rear end of the front edge 20a of the respective airfoil 20.
  • the brush segment 19a has moved towards the rear end of the printed product 30 and is about to press it against the co-rotating front edge 20a of the airfoil 20. This movement is supported by moving the blade end 20c onto the brush segment 19a.
  • FIG. 4b shows a position of the paddle wheel arrangement 2 after a rotation of the drive shaft 1 by 4 ° with respect to the 0 ° position shown in FIG. 4a.
  • the printed product 30 is gripped by the brush segment 19a and pressed against the front edge 20a of the airfoil 20, although the maximum value of the braking force has not yet been reached.
  • the belt tension is carried out by the belt tensioning roller 4, which is in contact with the drive belt 21 from above, as shown in Fig. 4b. From Fig. 4b it can also be seen that the printed product 30 is largely immersed in the paddle wheel pocket 22 in this movement phase.
  • FIG. 4c shows a movement phase in which the paddle wheel arrangement 2 has rotated by 10 ° with respect to the position shown in FIG. 4a.
  • the brush segment 19a is in this rotational position on the front edge 20a of the airfoil 20.
  • the brushes 19 experience their maximum deflection because the blade end 20c has moved towards the brushes during rotation and thus contributes to increasing the braking force.
  • FIG. 4d shows the printed product 30 located in the paddle wheel pocket 22 after the paddle wheel arrangement 2 has been rotated by 30 ° with respect to the 0 ° position shown in FIG. 4a.
  • the printed product 30 is deposited by a scraper or the like on a delivery belt 32 located below the paddle wheel arrangement 2, which is pre-tensioned by a tensioning device 31 and is held under uniform tension.
