Definitions

  • the invention relates to a sheet guiding system for a printing press, which is arranged in the region of a transfer drum, which is located between an upstream and a downstream sheet guiding cylinder, the transfer drum having closed or essentially closed surfaces between its gripper rows and the sheet guiding system having at least one blowing device.
  • the sheets of drums and cylinders are fed through the machine.
  • the leading edge of a sheet is passed from one gripper row to the next.
  • a clean and flutter-free guidance of the sheets without smearing the printed surface is essential.
  • DE 43 42 203 A1 proposes to design a sheet guide system of the type mentioned at the outset in such a way that the sheet delivered from the upstream cylinder to the transfer drum is acted upon by air from above, that is to say in the direction of sheet transfer.
  • a hot air squeegee for drying the sheets is assigned to the upstream cylinder.
  • the arrangement of further air doctor blades is proposed for sheet guidance.
  • the suction openings are cyclically closed by the transfer drum when the transfer drum is rotated when the two gripper systems face each other horizontally.
  • the arch constantly covers most of the suction openings. This means that there is no constant air flow.
  • the moisture extracted from the bow accumulates in the air and remains inside the machine room.
  • the air that is blown in is swirled, oversaturated with moisture and, rather accidentally, led out of the machine. Since there are no targeted material flows (air, moisture, solvents, etc.), the drying result and sheet routing remain dependent on random factors.
  • the sheet guiding system described is also very complex and requires a lot of energy.
  • the invention has for its object to provide a simply designed sheet guide system of the type mentioned, in which the sheet guide and - if drying between the - by targeted material flows printing units is provided - the drying is improved with reduced energy consumption.
  • an air guiding element is arranged above the transfer drum at a short distance from the movement path of the gripper rows, which essentially extends an air space extending from the upstream to the downstream arch-guiding cylinder, with the exception of an air outlet opening between the air guiding element and the upstream arch-guiding cylinder closes at the top, and that a blowing device acts on the air space in the direction of the downstream arc-guiding cylinder with air.
  • the invention has the advantage that the air of the blowing device mentioned at the beginning is used several times with little mechanical outlay. It is used first to blow the sheet transferred to the downstream sheet-guiding cylinder, and then this blowing air is directed in the direction of the upstream sheet-guiding cylinder in order to achieve secure sheet guidance there as well. In addition, the drag effect of the upstream bow-guiding cylinder is used. Afterwards, part of the blown air is used as air for guiding the sheet conveyed by the transfer drum.
  • the sheets are relined with air so that fluttering is prevented or at least the vibrations are strongly damped. This is achieved in that the surface of the transfer drum and the sheet form a closed chamber in which the air is compressed. Therefore, a force always acts on the printed side of the sheet in the area of the sheet guiding system, whereby a safe sheet guiding is achieved.
  • a countercurrent area is created on the upstream sheet-guiding cylinder, which, if necessary, has a high drying effect.
  • the moist air flows out, and the drier air is used as sheet carrier air, which ensures safe sheet guidance in the area of the transfer drum and at the same time dries the sheet further.
  • the sheet is handed over to the downstream sheet-guiding cylinder, it is blown with fresh air and a swirl of air and fresh air, which in turn achieves a high drying effect.
  • the arrangement of the blowing device means that only dry air can be drawn in from outside the machine.
  • the blowing device is expediently arranged in such a way that it blows against the direction of sheet travel in the direction of the downstream sheet-guiding cylinder.
  • it can be arranged on the air-guiding element, it being further advantageous if it can be adjusted with respect to its alignment on the downstream sheet-guiding cylinder. In this way, the blowing direction can be optimized depending on the printed fabrics.
  • other arrangements of the blowing device are also conceivable. So it can also be arranged on the transfer drum. In this case, the blowing takes place in the machine cycle depending on the position of the transfer drum.
  • a further improvement of the sheet guidance in the area of the transfer drum can be achieved in that a sheet guiding device extends along the movement path of the gripper rows in the lower area of the transfer drum from the upstream to the downstream sheet-guiding cylinder.
  • This sheet guide can be closed or essentially a closed baffle.
  • An improvement in the sheet guidance on the upstream sheet-guiding cylinder is achieved in that an air-guiding device aligned in the direction of the latter is arranged below the air-guiding element between the movement path of the gripper rows and the upstream sheet-guiding cylinder.
  • This can consist of sheets lying parallel to the air guiding element, can be designed as a lamellar grille or guiding grille or as guide channels. This creates a vortex-free laminar air flow, which ensures that a sheet is securely supported on the upstream sheet-guiding cylinder.
  • the ends of horizontally running sheets of the air guiding device are provided with bends directed towards the upstream sheet-guiding cylinder, the sheet blowing is further intensified. Such a bend can also be provided at the end of the air guiding element, which serves the same effect.
  • a further intensification of the blowing on the upstream sheet-guiding cylinder can be achieved in that the Air outlet opening is designed as an air outlet duct.
  • the air for the blowing is further compressed and the area of air supply to the upstream sheet-guiding cylinder is further enlarged.
  • a dryer can be arranged in this air outlet channel, which intensifies the drying. It can be designed as a radiation dryer with ultraviolet or infrared radiation or as a dryer which blows the sheet with additional dry, possibly also warm air. Of course, you can also combine both.
  • the air space, which the air guiding element closes at the top is closed as far as possible.
  • the distance from the drums and cylinders to the side wall is as small as possible, or an improved closure of this space can be achieved in that the transfer drum is equipped with side sealing washers.
  • additional wall elements or elevations of the side walls can be provided which form a relatively tight seal with these side sealing disks, which only have narrow gaps which are required for the rotation of the parts.
  • Another possible embodiment provides that the air outlet and the air inlet are connected to one another for air circulation.
  • means for extracting the air humidity are arranged between the air outlet and the air inlet.
  • Such a configuration should be provided in particular when colors are processed which, in addition to the moisture, also contain solvents which should not get into the work space.
  • a further development which provides that an air inlet leading to the blowing device leads into the printing machine and an air outlet downstream of the air outlet opening leads out of the printing machine to improve the removal of the moist and supply of air that is as dry as possible.
  • the air inlet and the air outlet can be formed, for example, by openings in a tread plate, preferably in the form of grilles.
  • Such a step plate as it is arranged between the printing units of a multi-color printing press, can also serve as an air guiding element at the same time.
  • the air outlet is not discharged into the work area but to the outside.
  • the possibility of such controlled removal of the exhaust air is possible due to the closed space formed by the device. It is another great advantage of the invention, since in this way the health conditions of the work rooms can be improved and the exhaust air can be fed to a cleaning facility.
  • the sheet transfer area can take over the function of a drying section, whereby the use of an additional drying unit, e.g. between two painting units, can be omitted and a more compact design and associated cost savings can be achieved.
  • the air guiding element can be attached to the machine by means of a hinge, in such a way that it is directed upwards can be folded away. In this way, the transfer drum is easily accessible. This serves for better maintenance and cleaning of the machine.
  • Fig. 1 shows a first embodiment of a sheet guide system for a printing press. It is arranged on a transfer drum 1, which is located between an upstream sheet-guiding cylinder 2 and a subsequent sheet-guiding cylinder 3.
  • the sheet-guiding cylinders 2 and 3 are impression cylinders.
  • the transfer drum 1 can, however, also be located between other cylinders, for example painting cylinders or drums, which are used for the transfer of sheets.
  • the arrangement in a turning device is also conceivable.
  • the sheet-guiding cylinders 2 and 3 in the exemplary embodiment act together as impression cylinders with rubber cylinders 24, the sheets 12, 12 ', 12''being printed in the gap between the two cylinders.
  • the transfer drum 1 has two rows of grippers 4. However, the sheet guiding system is not limited to such a transfer drum 1, three, four or more rows of grippers 4 may also be present. It is essential that there are closed or essentially closed surfaces 5 between the rows of grippers 4. These are necessary to achieve the effect similar to that of a rotary piston.
  • the directions of rotation of the cylinders 2, 3 and 24 and the transfer drum 1 are indicated by arrows 47.
  • Above the transfer drum 1 there is an air guide element 8, which is located at a short distance from the movement path 7 of the gripper rows 4. This distance must be such that a collision-free movement of the transfer drum 1 is guaranteed in any case.
  • the air guide element 8 extends from the upstream sheet-guiding cylinder 2 to the downstream sheet-guiding cylinder 3, although it does not necessarily have to end with one of these cylinders 2 or 3, but can also extend, for example, to one of the two rubber cylinders 24. It is essential that an air space 9 extending from the upstream sheet-guiding cylinder 2 to the downstream sheet-guiding cylinder 3 is formed, which is essentially limited by the cylinders 2, 3 of the drum 1, the air guiding element 8 and other side walls, not shown. This air space 9 is said to be essentially sealed, with the exception of an air outlet opening 10 which is located at the end of the air guiding element 8 facing the upstream arc-guiding cylinder 2.
  • air guiding element 8 is formed by a blowing device 6, which is pivotably arranged on air guiding element 8 by means of a movable, tight connection 25.
  • This pivotable arrangement of the blowing device 6 makes it possible to set the blowing direction of the supplied air 34.
  • This supplied air 34 is directed to an action area 27 of the downstream sheet-guiding cylinder 3. It serves to achieve a smooth, flutter-free arch guidance on this cylinder 3.
  • It is essential for the air guiding element 8 that, with the exception of the air outlet opening 10, it seals the air space 9 upwards as well as possible, but the distances to the moving parts that are required for a collision-free run must be observed.
  • the seal to the side can be made in that the air guide element 8 projects as close as possible to the side walls.
  • the cylinders 2, 3 and 24 can also be sealed by protruding as far as possible from the side walls.
  • Those can be designed in such a way that they correspond to the movement path 7 of the gripper rows 4 or are slightly larger. It is also possible for parts of the side walls, for example those which lie between the rotating parts, to have an elevated design and in this way to provide an even better seal.
  • the seal can also be provided by additional lateral components such as plates, sheets, etc., which are attached to the side wall.
  • a sheet guiding device 11 is arranged on the lower side of the transfer drum 1, which is located outside the movement path 7 of the gripper rows 4 in such a way that an sheet 12, 12 ′, 12 ′′ on it, if possible without contact can be guided along.
  • the sheet guide device 11 can be designed as a closed guide plate or as a floating guide. In the latter case, it can be a nozzle plate, which ensures that the sheets 12, 12 ', 12''are guided along an air cushion. This embodiment is particularly useful when sheets are to be printed on both sides and therefore contact with the outside of the sheets should be avoided in any case.
  • an air guiding device 13 is arranged below the air guiding element 8 in the area between the movement path 7 of the gripper rows 4 and the upstream arc-guiding cylinder 2.
  • the air guiding device 13 can, for example, consist of sheets 14 lying parallel to the air guiding element 8, which point in the direction of the upstream arc-guiding cylinder 2 in order to achieve a laminar air flow in this direction.
  • further training is also conceivable, for example as guide channels, lamellar grids or standing guide vanes.
  • the air outlet opening 10 is preferably designed as an air outlet duct 18 shown in FIG. 1, which extends essentially parallel to the surface of the upstream arc-guiding cylinder 2 against the direction of rotation 47 of the cylinder 2.
  • This air outlet channel 18 serves to generate a jamming effect, the pressure of which results in good sheet guidance on the upstream sheet-guiding cylinder 2.
  • the accumulation effect arises from the fact that the exhaust air 33 emerging from the air outlet duct 18 meets the drag flow 37 of the upstream arc-guiding cylinder 2.
  • a dryer 19 can also be arranged on the air outlet duct 18.
  • It can be a radiation dryer which emits ultraviolet or infrared rays in the direction of the arcs 12, 12 ', 12'' emits, or it is also possible to operate the dryer 19 with blown air, with warmed blown air or with radiation and blown air.
  • the freshly printed side 51 of the sheet 12, 12 ', 12' ' is located in the area of the blowing or carrying air. Good guiding and drying of the sheet 12, 12 ', 12' 'between the printing nips 50 and 50' is thereby achieved.
  • Fig. 2 shows the work cycle designated I. in which the transfer drum 1 forms an air inlet chamber 28 in the position shown with the blowing device 6, the rubber cylinder 24 and the downstream sheet-guiding cylinder 3.
  • the conclusion downwards takes place through the sheet 12 or, if a sheet guiding device 11 is provided, also through this.
  • the blowing device 6 acts on this air inlet chamber 28 with freshly supplied, preferably dry and possibly heated air 34, the air flow being directed onto an action region 27 of the downstream cylinder-guiding cylinder 3, on which an arc 12 is located.
  • the air flow is preferably contrary to that Direction of travel of the sheet 12 directed.
  • the supplied air 34 and the sheet carrier air 35 enclosed between the sheet 12 and the surface 5 meet, with a swirl 36 taking place.
  • the air is thereby compressed in the chamber volume, which results in high compressive forces on the sheet in the transfer area between the transfer drum 1 and the downstream sheet-guiding cylinder 3 and in the area up to the pressure gap 50. This ensures a good sheet support on the cylinder 3. Furthermore, further drying of the sheet 12 can take place by means of the mixed air if the air 34 supplied is dry and / or heated air.
  • Fig. 3 shows the transfer drum 1 in a position after a further rotation, which corresponds to the previously described work cycle II.
  • the air inlet chamber 28 is opened towards an air outlet chamber 29, whereby part of the air from the air inlet chamber 28 flows out towards the air outlet chamber 29.
  • This outflowing air 49 is guided by means of the air guiding device 13 onto an active region 26 of the upstream sheet-guiding cylinder 2 in order to produce good guidance of the sheet 12 ′′ there.
  • This bow 12 ′′ is also fixed at its front edge with a row of grippers, not shown in FIG. 3, and is stretched and pressed towards the rear by the exhaust air 33, which flows out through the air outlet duct 18.
  • the transfer drum 1 has made another rotation and shows above that previously with III. designated work cycle and shows below the work cycle IV reached after a further 180 ° rotation.
  • the sheet 12 leaves the air inlet chamber 28 in the direction of the pressure gap 50, and the supplied air 34 of the blowing device 6 and the sheet carrier air 35 mixed with it leave as outflowing air 49 the air inlet chamber 28 in the direction of the air outlet chamber 29.
  • a first partial flow 31 is formed in the air outlet chamber 29, which flows as a sheet air 35 between the sheet 12 ′′ and the drum 1.
  • a second partial flow 32 is directed by the air guiding device 13 for blowing the part of the sheet 12 ′′ still located on the upstream sheet-guiding cylinder 2.
  • FIG. 5 shows a further rotation of the transfer drum 1, through which the first partial flow 31 is strengthened to form the sheet air 35.
  • the first partial flow 31 and the second partial flow 32 are formed, an advantageous air distribution occurs because the drier air has a higher density and forms the arc-carrying air 35 as the first partial flow 31.
  • the moist air forms the second partial flow 32, which serves to blow the arc 12 ′′ and is then discharged as exhaust air 33. Since the sheet 12 ′′ still has a lot of moisture on the upstream sheet-guiding cylinder 2, the air of the second partial stream 32 is able to absorb further moisture, despite its moisture from the sheet 12 ′′.
  • the air forms a counterflow region 44 with respect to the movement of the arch 12 ′′, as a result of which a high drying effect is achieved.
  • the exhaust air 33 hits the drag flow 37 of the upstream sheet-guiding cylinder 2. The meeting again results in an increase in pressure and a pressing of the sheet 12 ′′. The exhaust air 33 then leaves the machine.
  • FIG. 6 shows a fourth embodiment of the sheet guiding system.
  • an additional blowing device 17 is arranged below the air guide element 8 between the movement path 7 of the gripper rows 4 and the upstream arc-guiding cylinder 2.
  • This blowing device 17 is oriented in the direction of the sheet-guiding cylinder 2 and can, for example, consist of a series of transversely arranged fans which give the overflowing air an additional pressure increase. It can take the place of the air guiding device 13 or, in cooperation with it, blow the sheet 12 ′ on the upstream sheet-guiding cylinder 2.
  • the blowing device 17 interacts with sheets 14 lying parallel to the air guiding element, which have an angled portion 15.
  • the air guide element 8 also has such an angled portion 16.
  • the exhaust air 33 flows through the air outlet duct 18, on which a dryer 19 is arranged. Then the exhaust air 33 arrives at an air outlet 21 which is formed by openings 23 of the tread plate 22.
  • the openings 23 are designed as a grid.
  • an air inlet 20 is provided in the tread plate 22, through the supplied air 34 to the blowing device 6.
  • the air inlet 20 is also designed as a grid.
  • a further embodiment is conceivable in which the air guiding element 8 is formed by the tread plate 22, that is to say the air outlet opening 10 shown in FIG. 1 is provided directly in the tread plate 22 and the blowing device 6 is also arranged therein.
  • FIG. 7 shows a fourth exemplary embodiment, in which at least some of the air emerging from the air outlet opening 10 is fed to the blowing device 6 in order to produce a recirculating air duct 38.
  • FIG. 8 shows a diagram which shows the change in the moisture 41 of the arc 12, 12 ', 12''and the relative humidity 42 of the air.
  • the development of the path through which the sheet 12 passes and the moisture in the vertical are plotted horizontally, with FIGS. 8.2 to 8.5 showing the respective positions which correspond to those of FIGS. 2 to 5.
  • 8.2 shows the position after the transfer of a sheet 12 to the transfer drum 1 (work cycle III.), In which the air flows are divided into a first partial flow 31 and a second partial flow 32. Air is applied to the sheet 12 in the counterflow region 44 of FIG. 8, ie the air flows against the sheet transport direction. After this blowing, the second partial flow 32 becomes exhaust air 33 and the first partial flow 31 with less moisture becomes arc-carrying air 35.
