Definitions

  • the invention relates to a printing unit comprising at least one side wall, each with an outer side and an inner side, a stationary forme cylinder, a movably mounted transfer cylinder, wherein the transfer cylinder is variably mounted in its spatial position by means of a first linear guide fastened to the at least one side wall, a movably mounted impression cylinder, wherein the impression cylinder is variably mounted in its spatial position by means of a second linear guide fastened to the at least one side wall.
  • Printing unit configurations are known from the prior art in which either the transfer cylinder and/or the impression cylinder are arranged in a variable position by means of at least one pivotably mounted lever.
  • the DE 100 08 225 A1 discloses a format-variable printing unit in which the printing cylinders are mounted on linear guides and in which the side wall has an opening so that all linear guides are mounted on the front side of the side wall opening.
  • the DE 198 05 898 A1 discloses a format-variable printing unit in which the printing cylinders are linearly adjustable in their position relative to one another and in which the linear guides are arranged on the inside of the side wall.
  • the object is achieved by a printing unit according to claim 1.
  • the object is achieved by a device in which the first linear guide is arranged on the outside of the at least one side wall and in which the second linear guide is arranged on the inside of the at least one side wall.
  • the printing unit comprises two side walls for supporting the forme cylinder, transfer cylinder and impression cylinder on both sides, with a first linear guide being attached to the outside of each side wall and a second linear guide being attached to the inside.
  • the first linear guide and the second linear guide comprise a drive means for linearly adjusting the transfer cylinder and impression cylinder.
  • a drive means for linearly adjusting the transfer cylinder and impression cylinder Such an embodiment has the advantage that the adjustment of the impression cylinders can be motorized and, if necessary, completely automated.
  • Fig. 1 shows the basic structure of an exemplary printing unit 1. This comprises a plurality of printing cylinders arranged essentially one above the other, namely a forme cylinder 5, a transfer cylinder 6 and an impression cylinder 7, wherein the printing material web 9 runs between the transfer cylinder 6 and the impression cylinder 7.
  • the printing unit 1 is configured as an offset printing unit for single-sided printing of the substrate web 9
  • the upper printing cylinder which is in contact with the forme rollers arranged above, is designed as a plate cylinder, whereas the middle printing cylinder is designed as a transfer cylinder 6, also referred to as a blanket cylinder.
  • the lowest printing cylinder 2 shown in an offset printing unit is designed as an impression cylinder 7.
  • the diameters and thus the circumferences of the forme cylinder 5 and the transfer cylinder 6 are exchanged.
  • Fig. 1 In the example shown, the diameters of the forme cylinder 5 and the transfer cylinder 6 would be changed by exchanging the sleeves 8 attached to the forme cylinder 5 and the transfer cylinder 6. Due to the closed outer surface of such sleeves 8, these sleeves 8 can only be pulled off the front of the forme cylinder 5 or the transfer cylinder 6. Due to the variable diameters of the forme cylinder 5 and the transfer cylinder 6, the transfer cylinder 6 and the impression cylinder 7, for example, are mounted so as to be adjustable, although it is fundamentally also possible to mount the forme cylinder 5 so as to be adjustable. The adjustment of the transfer cylinder 6 and the impression cylinder 7, for example, can be achieved by the transfer cylinder 6 and the impression cylinder 7 being adjustably mounted in or on levers.
  • the transfer cylinder 6 is in a Fig. 1 not shown first linear guide 10 and the counter-pressure cylinder 7 is in a Fig. 1 second linear guide 11 (not shown), which is Fig. 1 expressed by the two straight arrows.
  • Fig. 2 shows a side view of the printing cylinders of the printing unit 1 located between the side walls 2, although for the sake of better understanding, apart from the forme cylinder 5, the transfer cylinder 6 and the impression cylinder 7, no other rollers such as inking unit, dampening unit etc. are shown.
  • the printing unit 1 comprises a first side wall 2-1 and a second side wall 2-2, wherein the first side wall 2-1 has a first opening 16-1 and the second side wall 2-2 has a second opening 16-2.
  • the first opening 16-1 extends beyond the forme cylinder 5 in order to Fig. 2 not shown sleeve 8 of the forme cylinder 5 in the axial extension of the forme cylinder 5.
  • the bearing housing of the forme cylinder 5 on the side of the first side wall 2-1, which is set aside for this purpose, is in Fig. 2 not shown.
  • the transfer cylinder 6 is arranged below the forme cylinder 5, in which Fig. 2
  • the transfer cylinder 6 is also shown in such a way that the corresponding sleeve 8 is not mounted on the transfer cylinder 6 and that the transfer cylinder 6 is ready for the sleeve 8 to be pulled on.
  • This can be seen from the fact that the first bearing block 13-1 including the bearing 14 has been withdrawn from the bearing journal 17 of the transfer cylinder 6 in the longitudinal direction of the transfer cylinder 6 and has been parked along the first linear guide 10 in the direction of the impression cylinder 7. In this state, the transfer cylinder 6 is held exclusively by the bearing 14 on the side of the second side wall 2-2.
  • the first bearing block 13-1 for supporting the transfer cylinder 6 on the side of the first side wall 2-1 is connected to a first sliding block 15-1 for adjustment or forms a structural unit with it, the first sliding block 15-1 is guided in the first linear guide 10, wherein the first linear guide 10 is arranged on the outer side 3 of the first side wall 2-1.
  • the outer side 3 of a side wall 2 is the side of a side wall 2 facing away from the printing cylinders, such as forme cylinder 5, transfer cylinder 6, or impression cylinder 7, whereas the inner side 4 is the side of a side wall 2 facing the printing cylinders, such as forme cylinder 5, transfer cylinder 6, or impression cylinder 7.
  • Such a definition of the outer side 3 as the side facing away from the printing cylinders and the inner side 4 as the side of a side wall 2 facing the printing cylinders is therefore also valid for printing units 1 with only one side wall 2 and floating mounting of the printing cylinders.
  • the transfer cylinder 6 Since, depending on the thickness of the sleeve 8 arranged on the forme cylinder 5 and depending on the thickness of the sleeve 8 arranged on the transfer cylinder 6, the transfer cylinder 6 must be adjusted in or against the direction of the forme cylinder 5 in order to come into contact with it, the transfer cylinder 6 must also be mounted so as to be adjustable as a whole.
  • the second bearing block 13-2 is connected to a second sliding block 15-2 on the side of the second side wall 2-2, or the second bearing block 13-2 itself forms the second sliding block 15-2, wherein the second sliding block 15-2 is mounted in a first linear guide 10 which is arranged on the outer side 3 of the second side wall 2-2.
  • This arrangement makes it possible for both the transfer cylinder 6 mounted on one side only and the transfer cylinder 6 mounted on both sides to be spatially adjustable relative to the forme cylinder 5, and wherein the forme cylinder 5 is guided in two first linear guides 10, wherein the two first linear guides 10 are arranged on the outer sides 3 of the two side walls 2.
  • the impression cylinder 7 Since the impression cylinder 7 also has to be adjusted towards or against the transfer cylinder 6, but its diameter does not need to be changed, the impression cylinder 7 is mounted on the side of the first side wall 2-1 in a third bearing block 13-3 and on the side of the second side wall 2-2 in a fourth bearing block 13-4.
  • the third bearing block 13-3 is either connected to the third sliding block 15-3 or the third bearing block 13-3 forms the third sliding block 15-3, wherein the third sliding block 15-3 is guided in a second linear guide 11 which is arranged on the inner side 4 of the first side wall 2-1.
  • the fourth bearing block 13-4 is either connected to the fourth sliding block 15-4 or the fourth bearing block 13-4 forms the fourth sliding block 15-4, wherein the fourth sliding block 15-4 is guided in a second linear guide 11 which is arranged on the inner side 4 of the second side wall 2-2.
  • This arrangement makes it possible for the impression cylinder 7, which is mounted on both sides, to be spatially adjustable relative to the transfer cylinder 6, and for the impression cylinder 7 to be guided in two second linear guides 11, the two second linear guides 11 being arranged on the inner sides 4 of the two side walls 2.
  • first linear guide 10 and/or the at least one second linear guide 11 can each comprise only one linear guide or several linear guides per printing cylinder and/or per side wall 2, since this is a purely structural design which depends, for example, on the rigidity and the structural type of the respective linear guide.
  • first linear guide 10 and/or the at least one second linear guide 11 can each comprise only one linear guide or several linear guides per printing cylinder and/or per side wall 2, since this is a purely structural design which depends, for example, on the rigidity and the structural type of the respective linear guide.
  • the present invention is also possible with one guide or more than two guides per first linear guide 10 and/or second linear guide 11.
  • the printing unit 1 in the case of very small web widths it is also possible to equip the printing unit 1 with only one side wall 2, so that the forme cylinder 5, the transfer cylinder 6 and the impression cylinder 7 are only mounted on one side, so that, for example, these cylinders are mounted in the second side wall 2-2.
  • the present solution can also be applied by guiding the transfer cylinder 6 in at least one first linear guide 10, wherein the at least one first linear guide 10 is arranged on the outer side 3 of the second side wall 2-2, and by guiding the impression cylinder 7 in at least one second linear guide 11, wherein the at least one second linear guide 11 is arranged on the inner side 4 of the second side wall 2-2.
  • Fig. 3 shows a three-dimensional view of the components of the printing unit 1 that are essential for the present invention, wherein in this view the outside 3 of the first side wall 2-1 is viewed.
  • Fig. 3 shows the printing unit 1 comprising a first side wall 2-1 and a second side wall 2-2, wherein the first side wall 2-1 has a first opening 16-1 through which sleeves 8 can be pushed onto the forme cylinder 5 and onto the transfer cylinder 6.
  • FIG. 3 shows a state in which the first bearing block 13-1 is still arranged on the cylinder journal 17 of the transfer cylinder 6, so that in this state the transfer cylinder 6 is supported on both sides, but it is therefore not possible to remove a sleeve 8 from the transfer cylinder 6 or to slide it onto it.
  • the transfer cylinder 6 can be adjusted linearly in the extension of the first linear guides 10 both in the direction of the forme cylinder 5 and in the direction of the impression cylinder 7.
  • Fig. 3 It can also be seen that the counter-pressure cylinder 7 is mounted in a fourth bearing block 13-4, which is connected to a fourth sliding block 15-4 or forms a structural unit with it, wherein the fourth sliding block 15-4 is guided in two second linear guides 11, which are arranged on the inner side 4 of the second side wall 2-2.

  • This makes it possible to adjust the impression cylinder 7 in the direction of the second linear guides 11 in order to position the impression cylinder 7 against the transfer cylinder 6, which has a variable diameter.
  • Fig. 4 shows a three-dimensional view of the components of the printing unit 1 which are essential for the present invention, wherein in this view the outside 3 of the second side wall 2-2 is viewed.
  • Fig. 4 shows the printing unit 1 comprising a first side wall 2-1 and a second side wall 2-2, wherein the first side wall 2-1 has a first opening 16-1 through which sleeves 8 can be pushed onto the forme cylinder 5 and onto the transfer cylinder 6.
  • Fig. 4 shows a state in which the first bearing block 13-1 is still arranged on the cylinder journal 17 of the transfer cylinder 6, so that in this state the transfer cylinder 6 is supported on both sides, but it is therefore not possible to remove a sleeve 8 from the transfer cylinder 6 or to slide it onto it.
  • the first bearing block 13-1 remains on the bearing journal 17, so that the transfer cylinder 6 is supported on both sides. Since the first bearing block 13-1 is connected to the Fig. 4 not visible first sliding block 15-1 or forms a structural unit with it and which in Fig. 4 visible second bearing block 13-2 with the Fig. 4 visible second sliding block 15-2 or forms a structural unit with it, and since both the first sliding block 15-1 in the first linear guide 10 arranged on the outer side 3 of the first side wall 2-1, which, however, Fig.
