- the passage of strip 3 is horizontal, that is to say it will move horizontally, more specifically from left to right.
- the press 1 comprises mainly, and successively along the direction of travel of the paper web 3, unwinders designated by the reference numeral 5, printing units 7 to 14, a dryer / cooler 16 and at least one folder 18 .
- the printing units 7 and 8 are for example intended to print in black, the units 9 and 10 in cyan, the units 11 and 12 in magenta and the units 13 and 14 in yellow.
- the printing units 7 to 14 have similar structures and only that of the unit 8 will now be described with reference to FIG.
- the unit 8 is a dual printing unit which comprises two printing units 20A and 20B arranged one above the other.
- the upper printing unit 20A and the lower printing unit 20B have similar structures so that only that of the group 20A will be described later and the structural differences between the groups 20A and 20B will be reported.
- the numerical references used for groups 20A and 20B will be distinguished by the use of suffixes A and B.
- the printing unit 20A mainly comprises a blanket cylinder 22A, a plate cylinder 24A, an inking system, a damping system and optionally an automatic or semi-automatic plate changing system. These different systems are classic and are not represented.
- the blanket cylinder 22A is intended to receive tubular blankets, that is to say in the form of sleeves.
- Such a tubular blanket 23 is shown schematically in FIG. 9.
- the printing unit 8 also comprises a mechanism 26 for supporting and moving the cylinders 22A, 22B, 24A and 24B.
- This mechanism 26, as well as the other elements mentioned above, are carried by the frame 28 of the printing unit 8.
- the frame 28 comprises two side walls 29 between which the cylinders 22A, 22B, 24A and 24B extend. Only one wall 29 is visible in FIG.
- the support mechanism 26 comprises two sets 30, each disposed on one side of the printing unit 8 and carried by the corresponding side wall 29 of the frame 28.
- the two sets 30 have similar structures. Only that of the assembly 30 visible in Figure 2 will be described later and the differences between the two sets 30 will be reported.
- the assembly 30 comprises receiving arms of the blanket cylinders 22A and 22B, respectively designated 32A and 32B, and the receiving arms of the plate cylinders 24A and 24B, respectively designated 34A and 34B.
- the arms 32A, 32B, 34A, 34B are articulated to the wall 29 at points 36A, 36B, 38A and 38B allowing them to pivot relative to the frame 28 parallel to the axes A22A, A22B, A24A and A24B of the cylinders 22A, 22B, 24A and 24B.
- the hinge points 36A and 36B are located in an intermediate region of the arms 32A and 32B and the hinge points 38A and 38B are located at the left ends of the arms 34A and 34B ( Figure 2).
- the ends of the cylinders 22A, 22B, 24A and 24B located on the side of the assembly 30 are respectively rotatably received in the arms 32A, 32B, 34A and 34B by means of bearings. Each cylinder can thus rotate about its respective axis A22A, A22B, A24A and A24B.
- This rotation of the rolls takes place under the action of a drive motor which may be common to the entire printing unit 8, or for example under the action of a separate motor for each group 20A and 20B, or under the action of four separate drive motors each driving a cylinder.
- a drive motor which may be common to the entire printing unit 8, or for example under the action of a separate motor for each group 20A and 20B, or under the action of four separate drive motors each driving a cylinder.
- the bearings of the arms 32A and 32B receiving the ends of the blanket cylinders 22A and 22B are themselves received in doors 35A and 35B respectively which can pivot relative to the rest of the arms 32A and 32B about axes A1 and A2, outward, to release the bearings and the corresponding ends of the cylinders 22A and 22B.
- the doors comprise jaws 37A and 37B for gripping the bearings. At least one of the jaws 37A and 37B is movable to release the corresponding bearing.
- the jaws 37A are loosened by moving the one movable, then the door 35A is opened by pivoting about the axis A1. The door 35A then passes through an opening 39 formed in the wall 29.
- counterweight systems are for example provided on the side of the other assembly 30.
- the assembly 30 also comprises connecting rods 40A and 40B respectively connecting the arms 32A and 34A and the arms 32B and 34B. Their structure is similar and only that of the rod 40A will be described later.
- the rod 40A is articulated to the arm 34A by a hinge point 41A.
- the rod 40A is connected via a pin 42A to the right end of the arm 32A.
- the pin 42A is received in a housing 43A of the rod 40A slightly elongated along the rod 40A.
- the pin 42A can thus move in translation along the connecting rod 40A, providing a possibility of deflection which can be about 4.5 mm, although this numerical value has no limiting character.
- the pin 42A also offers a possibility of pivoting of the rod 40A relative to the arm 32A.
- the possibility of movement between the rod 40A and the arm 32A is preferably determined so that it does not occur when the gear wheels are disengaged. the relative spacing of the arms 32A and 34A.
- the pin 42A When opening the door 35A, the pin 42A follows the door 35A and out of the housing 43A. It is possible to provide means for holding the connecting rod 40A in position so that, when closing the door 35A, the pin 42A can re-engage directly in the housing 43A.
- the link 40A has, at the right of the housing 43A, a region of weakness 46A formed by local thinning ( Figure 3). This region of least resistance 46A has been dimensioned to break under a predetermined tensile force.
- the unit 8 may comprise a detector 47A breaking the connecting rod 40A.
- This is for example a printed circuit board which is arranged on the connecting rod 40A at the right of the region 46A.
- This detector 47A is connected to the unit (not shown) for controlling the press 1 to, when a breakage of the connecting rod 40A has been detected, to cause the emergency stop of the press 1 and the passage of all units 7 to 14 in off-pressure shutdown configuration.
- the printing unit 8 comprises a system 48 for actuating the support and driving mechanism 26 of the rolls.
- This system 48 comprises similar elements on each side of the unit 8, and only the elements provided on the lateral side illustrated in FIG. 2 will be described hereinafter with reference to FIG. 4.
- the system 48 comprises a main cylinder 50 for moving the arms 34A and 34B for receiving the plate cylinders 24A and 24B.
- This jack 50 is for example a pneumatic cylinder with double effect. For example, it is fed with pressurized air via a valve 52 with four orifices and two positions (FIG 4) connected to a source 53 of air under pressure.
- the jack 50 extends between the straight ends of the receiving arms 34A and 34B and is articulated thereto.
- the jack 50 has in particular a retracted configuration (FIG. 4) and an extracted configuration (FIG. 5).
- the actuating system 48 also comprises an eccentric 54 spacing the arms 32A and 32B for receiving the blanket cylinders 22A and 22B. This eccentric 54 is intended to cooperate with stops 56A and 56B, carried by the receiving arms 32A and 32B.
- the eccentric 54 is rotatable relative to the frame 28 between a spacing position and a position of approaching the arms 32A and 32B.
- the position of spacing of the arms is illustrated by Figures 2, 6 and 7.
- the eccentric 54 is then in abutment against the stops 56A and 56B.
- the eccentric 54 is not supported on the stops 56A and 56B. This position is illustrated by Figures 4 and 5.
- the eccentric 54 is movable between its aforementioned positions under the action of an auxiliary jack 58, for example double acting.
- the cylinder 58 is supplied with pressurized air via a valve with four orifices and two positions.
- the auxiliary cylinder 58 has a retracted configuration (FIGS. 4 and 5) and an extracted configuration (FIGS. 2, 6 and 7).
- Flow restrictors 61 are interposed on the pneumatic circuits between the cylinders 50 and 58 and the valves 52 and 60 to ensure smooth movements of the cylinders 22A, 22B, 24A and 24B.
- the mechanism 26 for supporting and moving the cylinders and its actuating system 48 allow the printing unit 8 to have an in-press configuration and three non-pressure configurations, namely a non-pressurized change configuration. plate, an off-press blanket change configuration and an off-press stop configuration.
- Figure 4 illustrates the in-press configuration.
- the blanket cylinders 22A and 22B and the plate cylinders 24A and 24B are then applied against each other.
- the main cylinder 50 and the auxiliary cylinder 58 are in retracted configurations and the eccentric 54 is in the position of approaching the arms 32A and 32B for receiving the blanket cylinders 22A and 22B.
- the unit 8 can then print the paper web 3 which passes between the cylinders 22A and 22B at a pinch point 62 ("nip" in English).
- the cylinders 22A, 22B, 24A and 24B are rotated about their respective central axes.
- the plate or plates carried by the plate cylinders 24A and 24B are moistened and inked by the inking and humidification systems. These plates decode the ink from their printer regions on the blankets carried by the cylinders 22A and 22B, which in turn decal the ink on the strip 3, which is thus printed on both sides.
- valve 52 was controlled to change its position.
- the main cylinder 50 is thus passed into its extracted configuration.
- the arms 34A and 34B for receiving the plate cylinders 24A and 24B were then spaced from the position they occupy in the pressure configuration.
- the receiving arm 34A was pivotally lifted about the point 38A and the receiving arm 34B was pivotally lowered about the point 38B.
- the arm 34A has driven with it, via the rod 40A, the arm 32A which has also pivoted upward around the point 36A.
- the blanket cylinder 22A has thus risen.
- the receiving arm 32B has pivoted downwardly around the point 36B, under the effect of its own weight and that of the blanket cylinder 22B, and bears against a fixed stop 63B (FIG 2).
- a space 64 is then formed between the blanket cylinders 22A and 22B.
- the gap 64 has been formed by a lower uplift of the upper blanket cylinder 22A than the lowering of the blanket cylinder 22B lower.
- the displacement 11 of the upper blanket cylinder 22A, along the line L intersecting the axes of the cylinders, is in the described example of about 8.3 mm while the displacement 12 along the same line L the lower blanket cylinder 22B is about 20mm.
- the upper blanket cylinder 22A thus moved vertically by a height h1 of about 5 mm from the position it occupied in the pressure configuration.
- the lower blanket cylinder 22B has moved a height h2 of about 17mm from the position it occupied in the pressure configuration.
- widths d1 and d2 along the line L have been created between respectively the blanket cylinder 22A and plate holder 24A and the blanket cylinder 22B and plate holder 24B. These widths are respectively 3.5 and 1.8mm respectively.
- the lower blanket cylinder 22B can lift relative to the lower plate cylinder 24B, particularly in the circumstances to be described by the after.
- the configuration of Figure 5 is a configuration in which the space 64 is of a height H sufficient to allow the passage of the strip 3 printed by the printing unit 7 without it touches the blanket cylinder 22A and 22B.
- the band 3 may wrap around one of the blanket cylinders 22A and 22B. If it wraps around the upper blanket cylinder 22A, the space 66A, larger than in the other configurations described later, leaves more room for the band 3 to winding and therefore limits the risk of damage to the upper rolls, including the blanket cylinder 22A.
- the paper web 3 wraps around the lower blanket cylinder 22B, it will lift by pivoting the arm 32B upward as the lower space 66B is filled by the paper web. 3 winding up to a width d2 of 3.5 mm along the line L.
- the off-pressure shutdown configuration is therefore a first safety measure to limit the risk of cylinder damage in case of rupture of the strip 3.
- the connecting rod 40A or respectively 40B will break in its region 46A or 46B as soon as the predetermined force has been reached.
- the space 66A or 66B corresponding can then expand further, thereby limiting the risk of damage to the cylinders.
- the broken rods 40A or 40B can be replaced later with a much lower cost than the replacement of the blanket cylinder 22A or 22B, or another part of the mechanism 26.
- the rods 40A and 40B thus act as fuses mechanical
- Figure 6 illustrates the off-press blanket change configuration.
- valve 60 was commanded to change its position and the auxiliary cylinder 58 went into the extracted configuration.
- the eccentric 54 is therefore moved to the position of spacing the arms 32A and 32B.
- the arm 32A has thus pivoted upwardly around the point 36A, raising the upper blanket cylinder 22A.
- the distance d1 then reduced, for example by 1.7 mm, to reach 1.8 mm and the distance l1 increased by the same to reach 10 mm.
- the space 66A is then smaller than in the off-press-off configuration, but the space 64 is larger.
- a stop 63A (FIG. 2) was then actuated to bear against the end (on the left in FIG. 2) of the arm 32A, thus preventing its downward movement. Similarly, the left end of the arm 32B is always bearing against the fixed stop 63B. Note that no stop 63A or 63B is provided on the side of the unit 8 opposite to that shown in Figure 2.
- the blanket can also be changed on the printing unit 8 while other units of the press perform a print job.
- Figure 7 illustrates the non-pressure plate change configuration.
- valve 52 has been controlled to bring the cylinder 50 into an intermediate configuration between its retracted and retracted configurations.
- the lower plate cylinder 24B has thus been raised by pivoting up the arm 34B around the point 38B until it bears against the lower blanket cylinder 22B.
- the upper plate cylinder 24A has been lowered by pivoting down the arm 34A until it bears against the blanket cylinder 22A.
- the plate and blanket cylinders of each of the groups 20A and 20B are then applied against each other.
- Stops 68A and 68B (FIG 2) carried by the arms 32A, 32B, 34A and 34B are then in abutment on one another.
- the non-pressure plate change configuration makes it possible to ensure the removal and placement of the plates on the plate cylinders 24A and 24B, for example by a manual, automatic or semi-automatic process.
- the space 64 has a global height H sufficient for the web 3 to pass through the printing unit 8, for example after having been printed by the printing unit 7, without touching the blanket cylinders. 22A and 22B.
- the printing unit 8 can therefore be prepared, by installing the printing plates for a next print job, while the printing press 1 is performing another print job.
- non-pressure configurations described above thus make it possible to ensure the preparation of certain units of the press, for example 8, 10, 12 and 14, while other printing units, for example 7, 9, 11, 13 , perform another print job.
- the change from one print job to another can then be made in flight, that is to say while the paper strip 3 scrolls, even at full speed, without the need to cut the strip of paper or to re-engage.
- some printing units of the press 1 may be prepared in masked time, that is, while a print job is being performed by some other units of the press 1. This possibility is increased by compared to the state of the art, since even the blanket change of some units can be performed while the press 1 provides a print job, which was not the case in the state of the art.
- the press can save even more time, can have an even higher utilization rate and thus leads to lower costs.
- the paper strip 3 will have a downward arrow f between two printing units placed in an in-press configuration.
- FIG. 8 This is illustrated in FIG. 8 in which only the printing units 7 to 9 have been represented, the units 7 and 9 being in configuration in-press and the printing unit 8, located downstream of the unit 7 and upstream of the unit 9, being in the non-pressure plate change configuration.
- the paper strip 3 is, because of the arrow f, located at a lower level than it would occupy if the printing unit 8 was in an in-press configuration.
- the height h2 (fig.7) being greater than the height h1, the risks of contact of the band 3 with the lower blanket cylinder 22B are reduced and it is not necessary to provide means for guiding the band 3 between unit 8 and units 7 and 9.
- the printing units have other structures, for example with lines L inclined relative to the vertical opposite to that shown, it is the height h1 which can be greater than the height h2. Indeed, the arrow f can then be oriented upwards.
- the characteristics relating to the differences in heights h2 and h1 can be used with printing units having less off-press configuration than in the example described.
- Such printing units may, for example, not have an off-press blanket change configuration.
- the blanket change operation can not then be performed while the press 1 provides another print job.
- rods 40A and 40B can be used independently of the non-pressure configurations described above and different amplitudes of displacement of the blanket cylinders. It is also possible to use such rods for only one of the printing groups.
- other elements of the support and displacement mechanism 26 may, in addition to or in place of the connecting rods 40A and 40B, have a zone of weakness to form a mechanical fuse.
- a zone of weakness to form a mechanical fuse.
- the first security measure described above to limit the risk of damage to the cylinders can also be achieved with other support mechanisms and drive 26.
- the two spaces 66A and 66B can have in this configuration widths d1 and d2 greater than those they have in other non-pressure configurations.
- the enlargement possibility described for the space 66B can also be implemented for the upper printing unit 20A. This enlargement can thus be ensured, not by a displacement of the blanket cylinder, as described above, but by a displacement of the plate cylinder or even by a displacement of these two cylinders.
- the units 7 and 11 may be intended to print in black, the units 8 and 12 in cyan, the units 9 and 13 in magenta and the units 10 and 14 in yellow.
- the press 1 may comprise a number of printing units different from that of FIG. 1, preferably greater than 2, and all the printing units do not necessarily have the structure described above.
- the height H of the space 64 in the non-pressure configurations will be greater than 10 mm in order to allow the strip 3 to pass through the printing units which do not print, without touching their blanket cylinders. .
- this value should not be considered as limiting, other lower values that can achieve this goal.
- the height H allowing passage of the paper web 3 without touching the blanket cylinders depends in particular on the diameter of the blanket cylinders, the inclination of the line L relative to the vertical, the distance between the successive printing units and the drawing of the ink.
- These elements comprise a drawbar 70 which extends inside the frame 28 parallel to the axes of the cylinders 22A and 22B over substantially their entire length.
- the lateral ends of this bar 70 are releasably mounted each on a side chain 72.
- These side chains 72 are for example endless chains. Only one of the strands 74 of these chains 72 is shown in FIG. 10, the return strands having not been represented.
- Each strand 74 extends from one side of the press 1 through all the printing units 7 to 14.
- the press 1 also comprises a motor for driving the chains 72 so as to cause a horizontal displacement of the bar 70 of the printing unit 7 towards the printing unit 14, as shown by the arrow 78 on the figure 10.
- the ends of the bar 70 are fixed on the chains 72 at the entrance of the unit. 7.
- the front edge 80 of the paper web 3 has been previously fixed or is then fixed to the bar 70, then the bar 70 is caused to move as shown by the arrow 78.
- the bar 70 then pulls the paper strip 3 through the units 7 to 14 of the press and an operator can then recover the leading edge 80 of the strip 3 at the output of the printing unit 14.
- the tape engagement operation in the printing units 7 to 14 can therefore be performed by one person and at one time.
- the pulling of the band 3 in the printing units by virtue of the bar 70 makes it possible, in comparison with the conventional systems of band engagement where the band is only pulled from one of its sides, to keep a good centering of the band 3 in the printing units.
- the heights H important spaces 64 are particularly advantageous for such a mode of engagement of the band 3, since they allow the bar 70 to have a relatively large diameter, avoiding damaging bending.
- the bar 70 may be that used for the engagement operations of the strip 3 in the unwinders 5 and the dryer / cooler 16.
- the bar 70 is then adapted to be mounted on the drive devices and in the possible guides of the web engagement systems which are provided with these other elements of the press 1.
- the bar 70 can be moved by other types of chains than endless chains 72, or even by other drive devices. These drive devices may be provided only on one side of the press 1 and not both as shown in Figure 10.
- This type of engagement of the band can be used with a press 1 comprising only one unwinder, comprising a separate dryer and a cooler and / or not including a dryer.
- this type of engagement of the band 3 within the printing units of the press can be used independently of the characteristics described above and in particular those relating to the dimensions obtained for the height H of the spaces 64.
- FIG 11 shows a variant of the unit 8 of Figures 1 to 7, the valve 52 has been replaced by a valve with five ports and three positions. This valve 52 thus has an additional position called centering spring. In this additional position, the two outlets of the valve 52 are supplied by the air from the source 53. The two chambers 82 and 84 located on either side of the piston of the cylinder 50 are thus supplied with compressed air.
- the valve 52 first goes into spring centering position.
- the air pressures in the chambers 82 and 84 are therefore balanced and the cylinders 22B and 24B of the lower printing unit 20B descend under the effect of their own weight.
- the control unit of the press 1 causes the passage of the valve 52 in the position where the chamber 82 is supplied with pressurized air and the chamber 84 is vented.
- This pressure limiter 86 when arranged as in FIG. 11 upstream of the chamber 82, makes it possible to reduce the pressure in this chamber 82 relative to that in the chamber 84, when the valve 52 is in the centering position. spring. The pressure limiter 86 then makes it possible to slow down further the descent of the cylinders of the lower printing unit 20B during the transition to the off-press-off configuration.
