Definitions

  • This invention relates to apparatus for the printing of can bodies. More particularly, it relates to an improved apparatus for the continuous printing of the exterior surfaces of can bodies.
  • an impression blanket picks up ink from plate cylinders and applies the desired impression to the exterior surfaces of the can bodies being printed.
  • the can bodies are normally mounted on mandrels freely rotatable about their longitudinal axes. Each can body is rotated about the axis of its mandrel during the time in which contact is maintained between the can and the impression blanket.
  • can printing machines have been proposed that would enable the rotatable carrier to be r0- tated continuously during the printing operation.
  • Such continuously rotated carriers have a high plurality of arms mounted thereon. These arms are adapted for rocking movement and each generally supports a can-holding mandrel, on which the can being printed is carried.
  • Such continuously rotatable machines permit the printing of more than 200 cans per minute. Preferably over 500 cans per minute are printed on such continuously rotatable machines.
  • an impression member having movable impression segments.
  • Each segment is made independently movable so that the partic- "ice ular impression segment that would contact a can to be printed can be moved back to a non-operative position in the event that the absence of a can or a defective can were detected as approaching the can printing position.
  • a solenoid-operated air cylinder may be operated so as to move a suitable cam member into an operative position so as to cause or permit the desired blanket segment to move toward the center of the impression member.
  • FIG. 1 is a side elevational view illustrating the continuous can printing apparatus in accordance with the present invention.
  • FIG. 2 is a side elevational view illustrating a particular embodiment of the can printing apparatus of the present invention.
  • impression blanket 1 is mounted on a suitable driveshaft 2, driven by drive motor 3.
  • a suitable driveshaft 2 driven by drive motor 3.
  • plate cylinders 4 Positioned so as to contact impression blanket 1 are four plate cylinders 4.
  • Each of the plate cylinders is contacted by a conventional inker system designated generally by the numeral 5.
  • Each of these inker systems include ink form rollers, vibrator rollers and a fountain roll in contact with a source of ink supply, the arrangement of rollers in the inker system being well known in the art.
  • the cans 19 to be printed are fed to the can printing apparatus by means of can infeed 6.
  • a transfer and printing mechanism, generally designated by the numeral 7 carries the cans, in a continuous movement, into proximity with impression blanket 1 as shown in the drawing.
  • Impression blanket 1 is not a continuous blanket surface, but rather comprises a series of impression blanket segments 8 separated from each other by non-printing gaps 9. Each segment 8 is provided with its own tightening shafts 10, by means of which the blankets may be adjusted to the desired degree of tension in the manner wellknown in the art.
  • the eight individual blanket segments 8 are illustrated as equally spaced along the circumference of impression blanket 1 at radial angles of 45 from each other.
  • Each blanket segment 8 is equal in effective length or preferably slightly longer than the circumference of the can to be printed. This slight additional length permits a fine adjustment of the printing at the initial point of impact between the can and the impression segment by allowing the trailing end of a impression segment to print the portion of the can making initial contact with the impression segment.
  • effective length of the impression segment is meant the portion of each impression blanket that will contact the can to be printed.
  • the gap 9 between each impression blanket segment is at least equal in length to the effective length of each impression segment. Preferably, gap 9 is slightly longer than the effective length of each impression segment 8.
  • Each of the plate cylinders 4 are positioned so that contact between it and the blanket segment 8 commences at the time that contact between another impression segment 8 and a can to be printed is broken off. Likewise, contact between each plate and an impression segment is broken off before contact between another impression segment to a can being printed commences.
  • each of the plate cylinders 4 are positioned at 45 apart and in such a position that contact with the moving blanket segment 8 commences slightly after the trailing end of the segment 8 in the printing zone loses contact with the can that it has printed.
  • impression blanket 1 is continuously rotated in one direction at a speed sufiicient so that each blanket segment 8 contacts and completely prints one can that is fed into the printing position by the continuous rotation of printing mechanism 7.
  • the position of plate cylinders 4 are such that no printing from plate to impression blanket segment occurs during the printing from impression blanket segment to a can.
  • printing occurs from plate cylinder 4 to blanket segment 8.
  • impression blanket segments 8 are shown, any convenient number of impression blanket segments may be employed. Since the length of each segment must be equal or preferably slightly longer than the circumference of the can being printed, it will be appreciated that incorporating a greater or lesser number of segments in impression blanket 1 will require a change in the size of impression blanket 1 for any given size of can being printed. For example, if six segments were desired, a smaller diameter impression blanket would be employed in order to maintain the length of each impression blanket segment at the desired length. If, on the other hand, ten segments were employed, a larger impression blanket diameter would have to be employed in order that each segment length would equal the desired length. In any event, the impression blanket segments 8 are equally spaced around the circumference of impression blanket 1.
  • each of four plate cylpresent invention to position the plate cylinders apart from one another at some multiple of the radial angle corresponding to that associated with an impression segment and its corresponding non-printing gap.
  • any adjacent plates 4 could be positioned apart at an angle of instead of 45
  • the present invention also contemplates the use of any convenient or desired number of plate cylinders. Normally between one and five plate cylinders will be employed, although it would be possible to include additional cylinders depending upon the number of colors desired to be printed.
  • the size of the plate cylinder likewise is not a critical feature of the present invention provided, however, that the proper register is maintained so that each portion of an impression segment will be printed by the plate cylinder in the same manner as the corresponding portion of each other impression segment.
  • a solenoid-operated air cylinder of conventional design may be employed for this purpose.
  • Such an air cylinder 14 may be operated in response to the detection of the absence of a can or the presence of a defective can by a commercially available step-up type logic system 12, such as that marketed by Square D Company.
  • a signal from a standard metal or metallic sensing device or devices 11 may be employed to provide a signal to the solenoid 13 that operates air cylinder 14, causing the air cylinder piston rod to move the pivotable portion 16 of cam 15 toward the center of the impression blanket 1 about pivot 17.
  • Cam followers 18 secured to impression segments 8 will follow the surface of pivotable cam segment 16, causing the impression segment 8 to move to a non-printing position toward the center of the impression blanket. Similarly, movement of cam segment 16 back to the true circle, printing position will permit the next cam follower 18 to remain in the same are followed during contact with the non-pivotable portion of cam 15. Impression segment 8, in this event, will be in printing position as it approaches the printing zone.
  • the impression blanket comprises spaced apart, independently movable impression segments, each segment being at least equal in effective length to the circumference of the can being printed, and the non-printing gap between each movable impression segment being at least equal in length to that of said impression segments, the plate cylinders being positioned with respect to said impression blanket and spaced apart at approximately equal radial angles around the circumference of the impression blanket, each angle being equal to the angle occupied by each impression segment together with its corresponding gap, said plate cylinder being positioned so as to contact an impression segment at the time that contact between a different blanket segment and a printed can is broken, whereby the adverse effects of impact printing are minimized by avoiding printing blanket-to-can and plate-to-blanket at the same time.
  • each impression segment is slightly longer in effective length than the circumference of the can being printed.
