Application May 17, 1954, Serial No. 430,118
1 Claim. (Cl. 271-74) My invention relates to improvements in suction sheet delivery'mechanism for printing presses of the so-called Kluge type in which the sheets are delivered from the platen by suction arms.
The primary object of my invention is to provide the suction arms of such sheet delivery mechanism with extension suction sections swingable on the suction arms into set positions to pick up smaller pieces of printed stock than can be accomplished with the suction arms alone and which can be set to one side or the other so.that they will not interfere with feeding of stock to the platen.
Another object is to provide suction extension sections for the above purpose attachable to the conventional suction delivery arms without alteration of the arms.
Other and subordinate objects together with the precise nature of my improvements will become readily apparent when the following description and claim are read with reference to the drawings accompanying and forming part of this specification.
In said drawings:
Figure 1 is a fragmentary view in perspective illustrating my improved extension suction sections applied to the suction delivery arms of the Kluge type printing press;
Figure 2 is a fragmentary view in perspective illustrating how the sheet delivery arms may be used with my extension suction sections thereon to deliver narrow sheets from the platen;
Figure 3 is an enlarged fragmentary view in longitudinal section taken on the line 3-3 of Figure 1; and
Figure 4 is an enlarged view in perspective of one of the extension suction sections detached.
Referring to the drawings by numerals, 1 designates generally a press of the Kluge type forming the subject matter of U. S. Letters Patent No. 2,088,377, and which has been illustrated fragmentally herein as sulncient to a proper understanding of the sheet delivery mechanism and my improvements thereon.
The sheet delivery mechanism C comprises an oscillating track 57 in the rear of the platen 12 pivoted at its rear end, as at 58, on a bracket 59 on the frame 12 of the press 1. A carriage 60 carrying a tubular suction support 61 reciprocates on the track 57 toward and from the platen 12. A pair of hollow suction delivery arms 62 are carried by the carriage 60 at opposite sides of the platen 12. Clamps 63 mount the delivery arms on the support 61 for lateral swinging adjustment thereon and bodily adjustment laterally of the platen also for longitudinal adjustment toward and from the platen 12 to position said arms 62 relative to sheets on the platen 12. The delivery arms 62 terminate in front downturned suction tips 64. A suction hose 68 connects the support 61 to a suction source. A Y-fitting 67 on said support 61 and flexible hose 66 between said fitting and the rear ends of delivery arms 62 connect said arms 62 to said support.
' to an open position shown in the drawings.
The platen 12 rocks on trunnions 24 from a closed Sheet grippers 84 of bar form are carried by a gripper bar 85 position.
of which need merely be mentioned in passing since these mechanisms are fully disclosed in the previously mentioned patent to which reference may be had for.
I a complete understanding of this press.
' As the platen -12 is rocked into its fully open position, the carriage is moved forwardly on the track 57 to move the delivery arms. 67 over the front edge of the platen 12, the track 57 is rocked to swing the support 61 and delivery arms downwardly from the normal raised position, not shown, and the front ends of the delivery arms 64 are thus positioned for suction delivery of a sheet S off the platen after which said carriage 60 is moved rearwardly for delivery of the sheet S and said track 57 rocked to swing said arms upwardly to normal position. The arm 71 and link form part of the carriage moving means. Reference to the beforementioned patent may be had for further disclosure of the carriage moving means and for the track oscillating means.
According to my invention a pair of tubular exten sion suction sections are provided on the suction delivery arms 62 which are formed with front downturned sheet gripping suction grip ends 101 preferably enlarged. The suction sections 100 each include attaching means comprising a vertical cup shaped adapter 102 on its rear end from one side of which the section extends having an external rim flange 103. A gland nut 104 threaded onto the suction tip 64 of the associated suction arm 62 and underlying the flange 103 rotatably attaches the suction section to its suction arm 100 for lateral swinging thereon. A gasket in the gland nut 104 between the suction tip 64 and adapter 102 forms an air-tight seal between said adapter 102 and suction arm 62.
As shown in Figure 1, the extension suction sections 100 may be used to grip the work sheet A at the front edge of the platen 12 in the usual manner by adjusting the suction delivery arms 62 longitudinally rearwardly in the clamps 63. However, and as shown in Figure 2, by adjusting the suction delivery arms 62 forwardly longitudinally in the clamps 63, the extension suction sections 100 may be used for delivering narrow sheets S, or cards, from the platen 12 when placed against the usual rear or lower platen gauges 40. Obviously, the extension suction sections may be swung laterally so that the same will not interfere with the usual sheet feeding means, not shown, of such presses.
The foregoing will, it is believed, suflice to impart a clear understanding of my invention without further explanation.
Manifestly, the invention may be modified without departing from the inventive concept, and right is herein reserved to modifications thereof falling within the scope of the appended claim.
What is claimed is:
A sheet delivery mechanism for use in a printing press comprising a pair of movable suction delivery arms, said arms being laterally, longitudinally and angularly adjustably mounted on a tubular support, carriage means Patented Mar..25, .1958 l supporting said support for oscillatory movement whereby the arms are moved toward and away from the platen of the printing press, each of said arms having a perpendicularly disposed downturned suction-tipon-the free end thereof, a downwardly extending :adaptor-rotatably connected to each suction tip and having-a'closedlowerend, said adaptor having an externally fia-nged upper,
end, an internally flanged nut rotatabl-ysecuringa the upper end of the adaptor-to the suction tip, a disc' sealv disposed between the upper end of the adaptor and the suction tip, a laterally extending tubular extension rigid withand communicating with said adaptor adjacent the bottom 'there of for swinging-movement in a plane gen-1 erally parallel to the horizontal plane of-the arms about an axis defined by the longitudinal axis of the down-1 turned suction tip and adaptor, each of said extensions terminating in downturned suction grip ends generally parallel to the downturned tips on said delivery arms for delivery of narrow sheets onto the platen adjacent,
the edge thereof remote from said support, 'the swingwhereby'the unobstructed'area between the grip ends is provided with a greater variation than the unobstructed area between the suction tips on'the deliverytarms.
