Definitions

  • the present invention relates generally to printing presses, and in one of its aspects, to a method and apparatus for converting a web fed letterpress unit into a web-fed offset printing press unit.
  • the frames for the letterpress units are massive and reboring the frames in place for insertion of offset cylinders is impractical. Often reboring is impossible because the new bores would overlap the old bores. Moreover, completely replacing the equipment or completely reworking it is very time consuming.
  • inventive concept of the present application resides in the manner of conversion of an existing letterpress print unit to an offset printing unit through the incorporation of cylinder supporting means not originally present in the unit.
  • the means and method disclosed and claimed in this application represent an advance over the developments of Applicant found in the earlier application EP-A-0017 720., That developments differ from prior art devices which relate to convertable press units originally constructed to permit changes in operating mode.
  • US-A-3.470.816 to Piecha teaches a method to achieve size change using a frame which accommodates inserted assemblages of varying cylinder diameter.
  • US-A-3.616.751 to Mowry shows an alternative arrangement to accomplish size change through movable support members affixed to the exterior of a main frame. Each, however, contemplated that the pressure unit be initially constructed to provide this capability.
  • Applicant has directed his efforts to conversion of letterpress units which were capable of operating in only one mode, the letterpress mode. Such press units are normally found in the newspaper printing field. Applicant, in order to take advantage of modern plate making techniques and other advantages inherent to offset printing achieved the developments disclosed and claimed in earlier application EP-A-0017 720.
  • the inventive concept there was to reposition printing cylinders within a letterpress unit main frame through addition of auxiliary frames disposed inside the main frame walls. These auxiliary frames supported at least some of the printing cylinders usually the blanket cylinders in locations to provide for offset printing.
  • the present invention which is delimited via a vis this earlier application is an advance over that original breakthrough. Basically it achieves the result of conversion of a letterpress unit to offset and additionally provides advantages which were not present in the original development.
  • the repositioned cylinders are supported in the new configuration by a combination of external support means and internal support means each having cylinder supporting bearings.
  • the external support means is associated with only one main frame wall on the outside thereof.
  • the internal support means is at least associated with the inside of the opposite wall. It may further include a portion attached to the inside of the main frame wall to which the external support means is attached, thus providing a three bearing support along the cylinder, one bearing at one end inside the main frame and two at the other end, one inside the main frame, and one outside the main frame.
  • the cylinder supporting techniques of this invention are of significant importance in that the external support means positions a bearing immediately adjacent a drive gear train which may be located outside the main frame. With the prior development of the Applicant drive gears were located .between the main frame walls, or in one embodiment, positioned outside but substantially cantilevered from the nearest support bearing.
  • Brackets 4-5 there are shown auxiliary frames 44a, 44b, and 45.
  • brackets 126, 130 there are depicted brackets 126, 130, which form the internal and external support means.
  • a specifially configured bracket arrangement 160,166 is illustrated in Figures 8-13. Each embodiment however, provides the cylinder supporting advantages described above.
  • an offset press unit utilizing a main frame defining a pair of spaced apart walls having bores therein adapted to rotatably receive printing cylinders in an originally letterpress printing configuration, the steps comprising: disposing a pair of offset plate cylinders within said main frame and rotatably supporting said cylinders in spaced apart relation, disposing a pair of blanket cylinders within said main frame in a conversed configuration for offset printing and rotatably supporting each of said cylinders for rolling contact with the other and with one of said plate cylinders for offset printing, and providing an internal support means at the inner side of said walls having at least one cylinder supporting bearing, characterized by securing an external support means secured to the outside of only one of said main frame walls, and securing the internal support means to at least the inside of the other of said main frame walls and supporting at least one of said cylinders on said bearing of said internal and external support means.
  • the method of constructing an offset press unit of the kind cited advantageously comprises the further step of extending a shaft of each of said cylinders through a separate bore in said main frame wall to which said external support means is secured, and attaching a separate gear on each one of said shafts in mesh with the gear on each adjacent shaft to form a gear train.
  • a typical web fed letterpress unit referred to generally by reference numeral 10 prints on both sides of a web 11.
  • Letterpress unit 10 includes a main frame 12, a pair of plate cylinders 14 and 14a laterally spaced in frame 12 for mounting printing plates thereon, means including ink transfer rollers and cylinders or drums 16 and 16a and form rollers 18,18a, 20 and 20a for applying films of ink to the plates.
  • Letterpress unit 10 also includes a pair of impression cylinders 22 and 22a in respective rolling contact with the plates on the plate cylinder 14 and 14a, respectively.
  • the letterpress unit is driven by a horizontal shaft 24 which drives a vertical drive shaft 26 through bevel gears 28 and 30.
  • Vertical drive shaft 26 in turn drives the letterpress cylinders through gear train 32 which includes a spur drive gear 34 for cylinder 14, a spur drive gear 36 for impression cylinders 22 and a spur gear-bevel gear combination 38 driven by vertical shaft 26 through bevel gear 40.
  • gear train 32 which includes a spur drive gear 34 for cylinder 14, a spur drive gear 36 for impression cylinders 22 and a spur gear-bevel gear combination 38 driven by vertical shaft 26 through bevel gear 40.
  • spur gears On the far end of frame 12 are mounted spur gears corresponding to each of the plate cylinders 14 and 14a and each of the impression cylinders 22 and 22a so that the gear for plate cylinder 14 drives the gear for impression cylinder 22, and the gear for impression cylinder 22a drives the gear for plate cylinder 14a.
  • a web fed offset printing press unit converted from web fed letterpress unit 10 of Figures 1 and 2 is referred to generally by reference numeral 42. It includes main frame 12 comprising drive side main frame 12a and operating side main frame 12b, ink transfer rollers and drums 16 and 16a, and form rollers 18, 18a, 20 and 20a. It also includes the same driving mechanism through vertical shaft 26, bevel gear 40, combination spur gear-bevel gear 38 and spur gear 34.
  • Offset press unit 42 also has an internal support means for rotatably supporting cylinders in an offset configuration
  • internal support means includes an internal auxiliary frame 44a, 44b, affixed to main frame 12, comprising drive side internal auxiliary frame 44a and operating side internal auxiliary frame 44b inside main frame 12 for receiving cylinders.
  • the internal support means is internal in that it has bearing inside the main frame.
  • a pair of offset plate cylinders 46 and 46a are laterally spaced inside the frames for mounting printing plates thereon, and a pair of blanket cylinders 48 and 48a are inside the frames in close proximity to a position for rolling contact with the plates on the respective plate cylinder, cylinder 46 or 46a, and each other.
  • cylinder 46 to include a drum 50 and a shaft 52, it can be seen that the shaft for some cylinders extends beyond auxiliary frame 44a, 44b and even beyond main frame 12.
  • the cylinders are thus "inside the frames” in the sense that they are primarily between drive side main frame 12a and operating side main frame 12b.
  • Offset unit 42 also includes an external support means for rotatably supporting offset cylinders, external support means in this embodiment includes an external auxiliary frame 45 affixed to the outside of main frame 12.
  • external auxiliary frame 45 and operating side internal auxiliary frame 44b are bolted to operating side main frame 12b by bolts 47.
  • drive side internal auxiliary frame 44a is bolted to drive side main frame 12a by bolts 49.
  • Web fed offset printing press unit 42 also includes a gear train 54 outside of operating side main frame 12b for imparting motion from one of the cylinders, cylinder 46 in this case, to other cylinders, in this case cylinders 48, 48a, and 46a. It may be necessary to shorten drums 50 of the cylinders somewhat in order to allow more room within main frame 12 for auxiliary frame 44a, 44b. Gear train 54 can be moved outside of main frame 12 even if the shafts 52 of cylinders 46, 46a, 48 and 48a do not align with bores 76, 56a, 56b, 58a and 58b for the letterpress unit cylinders since bores 60b, 61 b, and 62b have been provided by enlarging the original bores.
  • bores for offset cylinders are provided by simply removing the bearings for the letterpress cylinders.
  • Many letterpress units have enough room in existing oiltight housing 63 for the addition of gear train 54.
  • a method for converting web fed letterpress unit 10 of Figures 1 and 2 into web-fed offset printing press unit 42 of Figures 3 and 4 comprises in combination the steps of removing the pair of letterpress plate cylinders 14 and 14a and the pair of letterpress impression cylinders 22 and 22a, placing inside main frame 12 a lower portion of an internal auxiliary frame 44a, 44b comprising drive side internal auxiliary 44a and operating, side internal auxiliary frame 44b for receiving offset cylinders in an offset printing press configuration, installing a pair of offset plate cylinders 46 and 46a, installing the lower portion of auxiliary frame 44a, 44b, and installing a pair of blanket cylinders 48 and 48a in close proximity to a position for respective rolling contact with the plates on plate cylinder 46 and 46a respectively and the other blanket cylinder.
  • the lower portions of the auxiliary frames can, of course, be completely installed prior to installing the cylinders, and the invention is not limited to the particular order of operations. It is simply easier to at least have the lower portions already inside the main frame before the cylinders are
  • a preferred method according to the present invention also includes installing a lower portion 45b of an operating side external auxiliary frame and installing an offset printing configuration gear train 54 on the outside of operating side external auxiliary frame 45.
  • the method also includes, prior to installing the lower portion of any auxiliary frame, positioning a template representative of that auxiliary frame against the respective side of the main frame, and with the template as a guide, forming holes in the main frame for bolting the auxiliary frame to the respective side of the main frame.
  • Installing an auxiliary frame includes bolting the auxiliary frame to the main frame with bolts 47.
  • the method also includes installing means 68a, 68b, 68c for bodily swinging cylinders through short radius arcs, which in the embodiment illustrated are eccentric sleeves, in the auxiliary frames extending from internal auxiliary frame 44b to external auxiliary frame 45 through bores holes 60b and 61 b of main frame 12b for rotatably receiving the respective offset cylinders.
  • Eccentric sleeves 68a, 68b, 68c on the drive side are simply rotatably mounted in drive side auxiliary frame 44a.
  • the step of providing bores in the main frame 12 comprises, where necessary, enlarging the bore sufficiently for receiving the eccentric sleeves on the operating side.
  • a preferred method includes removing at least one pair of form rollers, either 18 and 18a or 20 and 20a or both pairs, mounting micrometric adjusting sockets for receiving the form rollers for respective rolling contact by the form rollers for respective rolling contact by the form rollers with the plates of plate cylinders 46 and 46a after the pair of offset plate cylinders is installed, and then installing at least one pair of form rollers.
  • the ink drums of 16 and 16a be plated with copper, and that dampeners 64 and 64a along with dampener motions be added.
  • Gear trains 54 is also added. Gears 66 and 66a are added to plate cylinders 46 and 46a respectively for driving the inking rollers and drums.
  • Means 68a, 68b, 68c for bodily swinging each of blanket cylinders 48 and 48a is installed.
  • Means 68a, 68b, 68c is for bodily swinging the cylinders between a first position in which the blanket cylinders make contact with their respective plate cylinders and with each other for applying an inked image on opposite sides of a web fed between them, and a second position in which the blanket cylinders are displaced into a throw-off position in which the blanket cylinders are isolated from their associated cylinders.
  • Means 68a, 68b, 68c can be manually or hydraulically turned eccentric bearings. Such mechanisms are common in printing presses and are described in detail in US-A-3,329,086, issued to Pullen.
  • Means 68a, 68b, 68c can also be installed for bodily swinging each of the plate cylinders, and the positions mentioned can be accomplished by bodily swinging both plate cylinders and blanket cylinders.
  • auxiliary frames 44a and 44b and 45 Only a lower portion of auxiliary frames 44a and 44b and 45 has been discussed, and in some situations this may be the entire auxiliary frame. Referring again to Figures 3 and 5, another embodiment of a lower portion of auxiliary frame 44a, 44b will leave the bores for the cylinders exposed so that the offset cylinders can simply be lowered into place. The location of the top of such a lower portion is illustrated by line 116. A cap 117 is then attached to hold the cylinders and their respective bearings in place. This is similar to the common practice of capping main frames.
  • the present invention allows the removal of gears to the outside of the converted press frame which allows more room for the cylinders and, thus, a wider web width. It also reduces the cost of conversion from letterpress to offset printing. Having a third bearing surface on the operating side reduces the length of the gear overhang. The same apparatus could, of course, be used for reducing gear overhang on driving side gears. Moving the gears to the outside also allows more space for sockets and throw-off mechanisms.
  • the present invention takes advantage of the existing oil tight housing on the operating side of the press unit.
  • the present invention can easily be applied to color units and other units having a half deck or full deck.
  • the present invention permits the use of smaller and double bearings on the blanket cylinders.
  • the present invention also permits the use of rough bored holes in the main frame when necessary to enlarge or add bores. This is extremely important because of the difficulty of precision drilling holes in the main frame on site. Additionally, keeping the gears on the outside of the main frame allows the bearing surfaces on the internal auxiliary frame to be closer to the main frame, thus reducing the stress on the auxiliary frame.
  • FIG. 120 an alternative embodiment according to the present invention is referred to generally by reference numeral 120.
  • Main frame 12 has caps 118 and 118a which can be removed and which were originally used to aid in inserting letterpress cylinders into bores 112, 56a, 58a and 76.
  • plate cylinder 46a is rotatably supported by eccentric sleeve 122 and beveled roller bearings 124. The center of plate cylinder 46a in this case is moved sufficiently for proper location by means of eccentric sleeve 122 so that it is not necessary to enlarge bore 76 or install plate cylinder 46a in an auxiliary frame or other internal or external support means.
  • the internal support means in this embodiment includes a plurality of support brackets 126 and 126a affixed to main frame 12. Each support bracket 126 and 126a is associated with a particular bore, 56a and 58a respectively. The support brackets support the offset blanket cylinders, but similar brackets could be used for supporting other cylinders. In the case illustrated, support bracket 126 supports blanket cylinder 48a.
  • the external support means includes external support brackets 130 for supporting a portion of blanket cylinder shaft 52 which extends through bore 58a. Support bracket 126 and 130 as well as other support brackets include a support ring 134 and a flange 136 affixed to support ring 134. Bolts 138 secure the support brackets to main frame 12 through flange 136, and strength members 140 extend between support rings 134 and flanges 136 to give added strength to support rings 134 for supporting the cylinders.
  • a plurality of pilots 142 are affixed to the support brackets.
  • pilot 142 affixed to support bracket 126 is used to position bracket 126 with respect to its bore 58a.
  • a combination of support bracket 126 and pilot 142 is positioned on shaft 52 of blanket cylinder 48a on at least one end of the shaft, in this case the end nearest to bore 58a.
  • Blanket cylinder 48a is then positioned within frame 12 in close proximity to a position for respective rolling contact with the plates on plate cylinder 46a and an impression cylinder 146.
  • Support bracket 126 is then installed using pilot 142 to locate the bracket with respect to bore 58a.
  • the bracket is preassembled on the cylinder shaft so that the entire assembly is simply dropped into place.
  • the pilots will make enough contact with the original bores to accurately locate the pilots and hence the support brackets and cylinders. If it is necessary to provide additional room for cylinder shafts 52 and their associated eccentric sleeves, then rough bores 144 and 144a can be provided adjacent to the original bores 56 and 58a respectively, but since the rough bores do not have to be the same diameter as the original bores, and in fact can be much smaller they only have to accommodate the additional room needed by the eccentric sleeves and do not have to accommodate the bearings and other mechanisms, pilots 142 can make a precision fit with much of the original bore.
  • Shaft 148 of common impression cylinder 146 is supported by means 150 and 156 for rotatably supporting a shaft.
  • Pre-existing means 152 supports outer end of shaft 148.
  • Gear train 158 in this embodiment allows blanket cylinders 48 and 48a to be driven from spur gear 38 by the common impression cylinder 146.
  • Main frame 12 is bored so that shaft 148 extends all the way through main frame 12, supporting gear 38 and thus replacing a gear supporting shaft which was at location 132.
  • common impression cylinder 146 is driven through gear 38.
  • Plate cylinders 46 and 46a are driven on the operating side by their respective blanket cylinders.
  • a web can be wrapped around common impression cylinder 146 for applying multicolor images to one side of the web.
  • blanket cylinders 48 and 48a can be moved into a blanket-to-blanket mode of operation for applying inked images to opposite side of a web fed between them.
  • a support bracket 160 consisting of a support ring 162 and a pilot 164, which is similar to the support brackets shown in the previous embodiment, acts as an internal support means for the operating end of blanket cylinder 48.
  • a support assembly 166 includes internal support ring 168, external support ring 170 and pilot 172 which also acts as means for rigidly connecting internal support ring 168 to external support ring 170. Pilot 172 thus acts as means for rigidly connecting the external support bracket to the internal support bracket and locating the brackets with respect to the bore. Shaft 52 of blanket cylinder 58 and pilot 172 extend through bore 60a when support assembly 166 is installed. Support assembly 166 is held in place by internal bolts 174 and external bolts 176. The addition of shims between internal support ring 168 and frame 12a or between external support ring 170 and frame 12a on installation may be necessary to achieve a tight fit.
  • a support assembly 166a similar to support assembly 166 is installed to support blanket cylinder 48a.
  • Support rings 170 and 170a are designed to be large enough to form an interface 178 to aid in correctly positioning the two support assemblies.
  • means for bodily swinging blanket cylinder 148 through a short radius arc includes eccentric sleeve 180 rotatably supported by support bracket 160 on the operating side and pass through eccentric sleeve 182 which is part of support assembly 166, rotatably supported by support ring 168 and 170.

  • Means 188 in a preferred arrangement does not connect the entire peripheries of internal eccentric sleeve 184 and external eccentric sleeve 186, thereby reducing the required size of bore 60a.
  • support assembly 166 is completely assembled on the cylinder shaft prior to installation.
