JANEEK DRUM FOR DELIVERING PAPER SHEETS FROM MACHINES ET AL 2 Sheets-Sheet 2 Filed Sept. 16, 1965 INVENTORS v 727/12 s/azf 0n ece United States Patent 3,334,892 DRUM FOR DELIVERING PAPER SHEETS FROM MACHINES Jaroslav Janeek, Brno, and Jaroslav Jirus'e, Blansko,
Czechoslovakia, assignors to Adamovsk strojirny,
narodni podnik, Adamov, Czechoslovakia Filed Sept. 16, 1965, Ser. No. 487,816 2 Claims. (Cl. 271-51) shaft of a chain delivery system. The delivery discs have a smooth or rough circumference and are generally adjustable in accordance with the place where the printing on the paper sheet which has to be removed from the printing machine is performed. Other known arrangements for removing printed paper sheets use a stable drum with stable means. The drum is arranged on the main shaft of a chain delivery device. Other known arrangements for removing printed paper sheets use delivery bars with contact means. The delivery bars are connected with the chain bolts of the chain delivery device.
These arrangements have the drawback that the delivery discs depreciate fine paper on their contact places in that they crumple the paper and leave undesirable traces on the printed surfaces of the removed paper sheets. Stable drums restrict the access to the machine and cover the removed sheets so that the attendance of the machine is made more diflicult, particularly the cleaning of the printing cylinder, of the proper delivery means and also the control of the prints.
It is an object of this invention to provide an arrangement for delivering of printed sheets from printing machines which would enable an easy access to all parts.
It is another object of this invention to provide an arrangement where adjustments in case of changes of printing conditions can be easily and quickly performed.
It is still another object of this invention to provide an arrangement which would handle the paper sheets in a manner so as to leave the surface of the paper sheets smooth and clean.
With these and other objects in view we propose to use delivery means provided with a plurality of bars extending transversely between discs of said delivery means, said bars inserted on one end into said discs with a sufficient play, allowing a limited angular deviation of these bars with respect to the axis of said drum so that the bars can be removed and any adjustments or cleaning easily performed.
An embodiment of the object of this invention is shown on the accompanying drawing, showing in FIG. 1 an elevation and in FIG. 2 a top view upon a delivering drum of a sheet printing machine and in FIG. 3 a detailed view of a transverse bar of said drum with contact means for the paper sheets.
With reference to FIGS. 1 and 2 there is an impression cylinder 11 cooperating with a printing cylinder provided with grippers 8. A chain delivery means is arranged below said impression cylinder 11 with a delivery drum composed of two spaced apart delivery discs 2, 6 fixed on a shaft 12 with a plurality of bars 1 extending transversely between both delivery discs 2, 6. A number of contact discs 4 is arranged on said bars 1 in sliding fashion, provided with spring means opposing any axial or rotary "ice movement of said contact discs 4 on the bars. Both ends of the bars 1 are of reduced diameter, on one end the shoulder of the bar 1 rests against the surface of the disc 6, at the other end the part of the bar 1 with reduced diameter extends beyond the disc 2 and a spring 3 leaning against the shoulder of the bar and against the surface of the disc 2 prevents any movement of the bar 1 to the left. The corresponding hole in the disc 2 has a sufficient play, to allow a limited angular deviation of the bar 1 with respect to the axis of the shaft 12. The number of bars 1 and the number of contact discs 4 is chosen so as to provide a sulficient number of contact places on the whole active circumference of the drum composed of the discs 2, 6 and of the bars 1 with contact discs 4, so that under any circumstances the paper sheet delivered from the impression cylinder 11 is supported at a sufficient number of places so as to prevent any crumpling. Grippers 9 are provided on an additional bar 13 parallel with the bars 1. A table 10 receiving the delivered paper sheets is arranged below the drum composed of delivery discs 2, 6 with the bars 1. This drum is agitated by some means commonly used at machines of this kind.
The printed sheets 7 of paper which have passed the printing cylinders are taken over from the grippers 8 of the impression cylinder by the grippers 9 of the delivery drum and are delivered to the receiving table 10. The bars 1 with the adjustable contact discs 4 care for the correct bend of the paper sheet 7 and thus for a correct removal from the printing machine.
In case any changes have to made with the drum composed of the delivery discs 2, 6 and of the bars 1 provided with contact discs 4, each bar 1 can be easily removed by applying axial pressure against the force of the spring 3 until the end of the bar 1 supported within a hole of the disc 6 is beyond this disc, allowing the bar 1 to be deviated and to-be taken out of the disc 2. Any adjustments or cleaning can be thereafter made on the bars 1 before they are returned to their place.
What we claim is:
1. A drum for delivering paper sheets from machines, particularly from printing machines, comprising a shaft, two spaced apart discs supported by said shaft, a number of holes in thesediscs at equal distance from the axis of said shaft, a number of bars extending between said discs and engaging into said holes of both discs, a shoulder provided on one end of said bars, said shoulder resting against the surface of one of said discs, spring means urging the bar to remain in contact with this disc, the second end of the bar adapted to be pressed into the hole of the second disc against the action of spring force so as to allow the first end of the bar to be taken away from the first disc, sufiicient play between the holes of the second disc and the end of the bar so as to allow a deviation of the bar suflicient for taking away the bar altogether.
2. A drum as in claim 1 with contact discs arranged on said bars in sliding fashion with sufiicient friction to prevent any spontaneous shifting or turning of said contact discs with respect to said bars.
