Definitions

  • the present invention relates generally to cleaning systems for use in cleaning a cylinder of a printing press and, more particularly, to mounting mechanisms for cloth rolls on press cylinder cleaning devices.
  • a cylinder-operated take-up shaft is used to rotate the shaft, thereby drawing cleaning cloth from a supply roll towards the take-up shaft.
  • This incremental cloth advancing system is utilized to prevent an excessive amount of cleaning cloth from being drawn off of the supply roll, thereby preventing excess cleaning cloth usage and interference with the printing system.
  • relative rotation between the supply core and supply shaft must be prevented.
  • a jaw system has been utilized to couple the supply core to the supply shaft to prevent relative rotation therebetween.
  • This jaw system utilizes a series of pins or jaws to simultaneously grip both the supply shaft and the supply core.
  • This assembly has a brake mechanism and, once the assembly is coupled to the shaft sockets, an applied spring rewind force.
  • the incremental advancing system associated with the supply shaft will fail to prevent excess cleaning cloth from feeding into the printing system, since the brake and spring rewind are ineffective when the core remains uncoupled to the shaft. Rather, as the take-up shaft rotates, the supply core can rotate with respect to the supply shaft thereby feeding an excessive amount of cleaning cloth into the system. Accordingly, the printing system may jam in view of this excess cleaning cloth. As such, this excess amount of cleaning material is wasted when the supply core is not properly coupled to the supply shaft.
  • EP-A-0 539771 and EP-A-0 611651 disclose means to prevent relative rotation between the supply core and the supply shaft.
  • the means comprises a rubber member attached to the supply core to frictionally engage the inner surface of the supply core.
  • the present invention fulfils the aforementioned needs.
  • a cleaning material supply apparatus for a press cylinder comprising a supply shaft, a supply core and sheet cleaning material wound on the supply core, the supply core being disposed on the supply shaft and coupled for rotation therewith, characterised in that the supply core is coupled to the supply shaft through a keying engagement of an internal key structure on the supply core with a corresponding outer key structure on the supply shaft, configured to prevent relative rotation therebetween upon rotation of the shaft.
  • the internal key structure on the supply core may have a cross-section with a centre point and a perimeter, the perimeter having at least two points disposed at different distances from the centre.
  • the supply core may have an external structure with an external cross-sectional shape which is different from the internal cross-sectional shape of the supply core.
  • the internal key structure of the supply core may have an internal structure with an internal polygonal cross-sectional shape.
  • the internal polygonal cross-sectional shape of the supply core may have three, four, five or six sides.
  • internal structure of the supply core may have an internal structure with an oval cross-section.
  • the external key structure of the supply shaft may have a cross-section with a centre point and a perimeter, the perimeter having at least two points disposed at different distances from the centre.
  • the supply shaft may have an external structure with an external polygonal cross-section shape.
  • the apparatus may further comprise a housing in which the supply shaft is rotatably mounted and a take-up shaft wherein take-up shaft rotatably mounted in communication with the housing.
  • the take-up shaft has a cross-section with a centre point and a perimeter, the perimeter having at least two points disposed at different distances from the centre.
  • the supply shaft may have an external structure with an external polygonal cross-section.
  • the external polygonal cross-section may have three, four, five or six sides.
  • the supply shaft may have an external structure with an external oval cross-section.
  • the housing may comprise a locking finger having an unlocked position and a locked position, wherein the take-up shaft is rotatably coupled to the housing via the receiving slot when the movable locking finger is in the locked position.
  • the take-up shaft is configured to receive the cleaning material after the cleaning material has been used to clean the printing press.
  • the supply core may have first and second ends
  • the supply shaft may have first and second ends and may further comprise a first plug mounted on the first end of the shaft, and a second plug mounted on the second end on the shaft, a portion of each of the plugs being disposed within the supply shaft, and a portion of each of the plugs being disposed outside the supply shaft and extending beyond a periphery on the supply shaft to prevent the supply core from sliding off the supply shaft.
  • the press cylinder cleaning material may be a cloth fabric or paper.
  • the internal and external key structures may comprise a key member and a corresponding receptacle for the key member, the key member being movable in and out of keying engagement with the receptacle.
  • the key member passes through a side wall of the supply shaft.
  • the key receptacle is a slot cut into the supply core.
  • the supply shaft may have an internal lumen formed by at least one sidewall of the supply shaft, the supply shaft having a key slot passing from the internal lumen through the sidewall.
  • the key member is disposable in the key slot, the key member having an unlocked position in which the key member is maintained within an outer surface of the supply shaft and the key member having a locked position in which the key member protrudes beyond the supply shaft and into the key slot of the supply core to couple the supply core to the supply shaft.
  • At least a portion of a plug is disposable within the lumen of the supply shaft at least a portion of the plug extends beyond the supply shaft to maintain the supply core on the supply shaft.
  • the apparatus further comprise a slidable cam disposed within the lumen of the supply shaft, the slidable cam operatively associated with the key member and the plug, the slidable cam having an unengaged position corresponding to the unlocked position of the key member, the slidable cam having an engagede position corresponding to the locked position of the key member.

  • the cleaning system 10 comprises generally a rotatable supply shaft 20, a supply ore 30, a take-up shaft 40 and a housing 50, each of which will now be described in greater detail below.
  • rotatable shaft 20 is shown as it extends from a first end 60 to a second end 70.
  • rotatable supply shaft 20 generally has a solid structure except for a hollow portion at each end for receiving a portion of a plug.
  • a first plug 80 is disposed at and within first end 60 of rotatable supply shaft 20 .
  • a second plug 90 is disposed at and within second end 70 of rotatable supply shaft 20 .
  • Each of these plugs 80,90 has a portion disposed in a hollow end portion of rotatable supply shaft 20 .
  • Each of these plugs 80,90 also has laterally extending side portions which extend beyond the circumference of rotatable supply shaft 20 to prevent a supply core 30 , which is disposed around rotatable supply shaft 20 , from sliding off of rotatable supply shaft 20 .
  • Each plug 80,90 also has a socket-engaging portion 100,110 which allows the plugs (and therefore rotatable supply shaft 20 ) to engage within rotatable sockets 120,130 . Once engaged, the supply shaft 20 and plug arrangement can move/rotate with respect to the sockets 120,130 under brake load and spring rewind tensions.
  • Rotatable sockets 120,130 are rotatably disposed within housing 50 such that, when a rotational force is applied to rotatable supply shaft 20 , rotatable supply shaft 20 , in conjunction with plugs 80,90 and sockets 120,130, rotate about a rotational axis 140 of rotatable supply shaft 20 .
  • rotatable shaft supply 20 is made of aluminum.
  • Plugs 80,90 and sockets 120,130 are preferably made of plated steel and housing 50 is preferably made of aluminum. It is to be understood, however, that other suitable materials may be used for these elements.
  • supply core 30 is shown disposed around rotatable supply shaft 20 .
  • supply core 30 extends from a first end 150 to a second end 160 .
  • Supply core 30 has an internal elongated hole which extends from first end 150 to second end 160 for receiving rotatable supply shaft 20 therein.
  • supply core 30 is made of cardboard, although it is to be understood that other suitable materials may be used.

  • this cleaning material 170 is such as those disclosed in U.S. Patent No. 5,368,157, herein incorporated by reference, although it is to be understood that other types of cleaning materials 170 , such as cleaning films, may be used.
  • the rotatable supply shaft 20 has an outer cross-sectional shape 180 and the supply core 30 has an inner cross-sectional shape 190 which couples the rotatable supply shaft 20 with the supply core 30 to prevent relative rotation therebetween.
  • rotatable supply shaft 20 has an cross-section with a polygonal (figs. 3A-3E) or oval (fig. 3F) outer shape, while supply core 30 has a cross-section with a polygonal (figs.

  • the external cross-sectional shape of the supply core 30 may vary from the internal cross-sectional shape of the supply core 30 . Accordingly, in Figure 3E, a core with a round external shape and an internal cross-sectional square shape is shown. Accordingly, the core may outwardly appear to be a cylindrical shape, while the internal structure may have a non-cylindrical shape.
  • the outer cross-sectional shape 180 of the supply shaft 20 and the inner cross-sectional shape 190 of the supply shaft 20 may be any non-circular shape.

  • outer cross-sectional shape 180 of the supply shaft 20 need not be the same as the inner cross-sectional shape 190 of the supply core 30 provided that these shapes cause the supply shaft 20 and supply core 30 to couple so as to prevent relative rotation therebetween.
  • such a structural arrangement allows the rotatable supply shaft 20 and supply core 30 to rotate in unison thereby facilitating the dispensing of cleaning material 170 as the supply shaft 20 and supply core 30 rotate together.
  • a rotatable take-up shaft 40 of the present invention is shown.
  • the rotatable take-up shaft 40 extends from a first end 192 to a second end 194 . Disposed at each respective end is a protrusion 196,198 disposed in communication with the housing 50 .
  • the take-up shaft 40 preferably has a polygonal shape such as triangular (fig.5A), rectangular (fig.5B), pentagonal (fig.5C) or hexagonal (fig. 5D), so that used cleaning material 170 may be wound around the take-up shaft 40 without needing to resort to a rough jagged surface texture on the take-up shaft 40 .
  • the take-up shaft 40 may assume various non-circular shapes.
  • cylinder 199 is disposed in communication with a take-up shaft 40 to rotate the take-up shaft 40 during cleaning of a press cylinder.
  • the cylinder 199 rotates the take-up shaft 40 thereby drawing cleaning material 170 off the supply core 30 and rotating the supply core 30 and supply shaft 20 (in conjunction with the incremental advancing system disclosed in U.S. Patent No. 5,176,080).
  • take-up shaft 40 is made of aluminum although it is to be understood that other suitable materials may be used.

  • the supply shaft 200 has an internal lumen 260 which contains essential elements of the key system.
  • the supply shaft 200 also contains slots 270,280 in its sidewall.
  • the keys 240,250 pass through slots 270,280 to engage the supply core 210 via key receivers 220,230 to couple the supply shaft 200 to the supply core 210 to prevent relative rotation therebetween.
  • the key receivers 220,230 While the key receivers 220,230, at a minimum, must be large enough to receive the keys 240,250, the key receivers 220,230 are preferably somewhat larger than this minimum size so as to provide a clearance gap to facilitate manufacturing tolerances for the supply shaft 200 , supply core 210 and key system.
  • a transverse pin 290 is preferably utilized to prevent the key system from being pushed too deeply into the lumen 260 .
  • the supply shaft 200 may simply be made solid in the region to the right of the transverse pin 290 in figure 8 so as to maintain the entire key system to the left thereof.
  • a spring 300 is disposed to the left of the transverse pin 290 in figure 8. This spring 300 may be attached at one end to the transverse pin 290 via clip. The other end of the spring 300 is placed into contact with a slidable camming member 310 .
  • the spring 300 is attached to at least transverse pin 290 or the slidable camming member 310 to assure that the spring 300 is always disposed between the slidable camming member 310 and the transverse pin 290 .
  • Such an arrangement assures that the spring 300 will impart a force against the slidable camming member 310 and the transverse pin 290 as the camming member 310 is slid from retracted (unlocked) position, as shown in figure 8, to a locked position, as shown in figure 9.
  • Slidable camming member 310 has a first inclined camming surface 320 to engage a first key 240 , and a second inclined camming surface 330 to engage a second key 250 .

  • the plunger 410 is preferably as long as (1) the slot 350 plus (2) any distance between the end of the slidable plunger 410 and the end of the supply shaft 200 .
  • the laterally extending protrusion 420 of the plug 400 extends beyond the circumference of the supply shaft 200 so that the protrusion 420 assists in preventing the supply core 210 from sliding off the supply shaft 200 .
  • the plug 400 need not have such a laterally extending side member.
  • the plug 400 also has a locking pin 430 which is slid through a locking pin receiving slot 440 in the sidewall of the supply shaft 200 to a locking slot 450 which is also in the sidewall of the supply shaft 200 .
  • the plug 400 To lock the plug 400 onto the first end 60 of the supply shaft 200 , the plug 400 need only be turned a small amount such that the locking pin 430 enters the locking slot 450 and engages the sidewall of the supply shaft 200 surrounding this locking slot 450 . It should be noted that such a key system can be built with only one key and one slot in the core and shaft, rather than two key/two slot arrangement shown in the drawings.
  • plated steel and other metallic materials are to be used in such a key system, although it is to be understood that other suitable materials may be used.
  • the key 500 protrudes from the sidewall of the supply shaft 510 .
