Definitions

  • ABSTRACT A continuous printer and skip-print mechanism comprising a plurality of blanket holder segments on a rotated drum successively movable into and out of printing position, a stationary cam, a cam follower on each segment, and operative connections including a withdrawable bridge member between the cam follower and each blanket holder segment for moving the segment into printing position.
  • An air cylinder or other suitable mechanism responsive to the malfunction signal actuates a pivotally mounted trigger and connecting rod which are part of skip-print means for withdrawing the bridging member from the operative connections between the cam follower and each blanket holder segment, thereby producing a gap in the operative connections and preventing movement of the segment into printing position when malfunction occurs, without interrupting subsequent printing operations.
  • This invention relates to a continuous printer and skip-print mechanism for printing the exterior cylindrical surfaces of containers and other objects, and for automatically preventing the printer blanket segments from moving into printing position in' the event of malfunction of the machine.
  • the invention is embodied in a printer and transfer unit combination for placing containers on mandrels, printing the containers, followed by removal of the containers from the mandrels and placing them on a peg-carrying chain or other conveyor for subsequent operations thereon.
  • the transfer unit may be of the type shown and described in US. Pat. No. 3,26l,28l, to Ruben J. Hartmeister, assigned to the assignee of this application, or the printer and skip-print mechanism of this invention may be used in combination with other transfer mechanisms.
  • the printer comprises a rotated drum provided with a plurality of blanket holder segments pivotally mounted thereon and movable into and out of printing contact with the containers or objects to be printed.
  • the drum is suitably juxtaposed with, and connected by gearing to, the aforementioned transfer and work holding unit.
  • eight such segments are employed.
  • the blanket holding segments are moved successively into printing position, one segment being moved by a cam into printing position while the rest remain retracted and stationary relatively to the printer drum while the latter is rotated continuously.
  • the skip-print mechanism automatically inactivates the mechanism which normally would move the corresponding blanket holding segments into printing position.
  • An important object of this invention is to provide skipprint means responsive to a signal of malfunction in the machine, whereby a blanket holder segment is automatically inactivated and prevented from contacting or printing afaulty container or a mandrel without a work piece thereon.
  • This object is achieved by tripping mechanism responsive to the malfunction signal, said mechanism controlling the position of a transfer block, referred to herein as a bridging member, without interrupting the continuous operation of the following printing movements.
  • the bridging member functions to transmit motion from a cam follower to a blanket holder segment for the purpose of moving the blanket segment into printing contact with a container to be printed.
  • the bridging member In the event of malfunction, the bridging member is automatically withdrawn, and thus prevents the cam follower from transmitting motion to the blanket holder segment by leaving a gap in the operative connections between the cam follower and blanket holder segment.
  • the blanket holder segment is automatically inactivated and held in stationary position relatively to the printer drum.
  • This mode of operation difiers from prior art printers which permit movement of the segment into printing position and in the event of malfunction require retracting of the blanket holder segment relatively to the drum on which the segments are mounted.
  • FIG. 1 is an elevational side view, partly in section, showing part of a printer drum with one of a plurality of printer blanket holder segments mounted on the drum, showing also part of a cam which actuates a cam follower for operating the blanket holder segment, and mechanism for automatically tripping the skip-print means, the parts being shown in the printing positions.
  • FIG. 2 is a view similar to FIG. 1, on an enlarged scale, the parts being shown in the skipprint positions.
  • FIG. 3 is a transverse vertical sectional view on an enlarged scale, in the plane of the line 33 of FIG. 2.
  • FIG. 4 is a transverse vertical sectional view on an enlarged scale, in the plane of the line 4-4 of FIG. 2.
  • a continuously rotating printer comprises a blanket holder drum l0 and a plurality of blanket holders I1 and printing blankets 12 mounted on the drum. Only one of the blanket holders 11 and part of another are shown in the drawings, though usually eight such blanket holder segments, equally spaced from each other circumferentially on the drum, are employed in the printer.
  • Each blanket holder segment 11 is pivotally mounted near its leading edge on a shaft 13 in bearings 14, as best shown in FIG. 4.
  • Each holder has a bar I5 attached to its trailing edge which is free to move radially outwardly relatively to the holder drum 10.
  • the blankets 12 are held on the holders 11 by means of the ratchet shaft 16 and stationary shaft 17.
  • a ratchet l8 and pawl 19 hold the blanket taut on the holder 1 1.
  • a cam follower frame 20 is mounted in bearings 21 held in place by screws 22 in blanket holder segment 11.
  • a cam follower 23, mounted on an eccentric adjusting shaft 24, is actuated by a cam 25 which is part of a stationary cam-ring 26.
  • a spring 27 is mounted on the blanket holder segment 11 on a retainer 28, for holding the stop bar 15 against the stop 31.
  • a spring 29, mounted on spring retainer 30, holds the cam follower 23 against the cam 26-26.
  • the motion transmitting mechanism between the cam follower 23 and the blanket holder segment 11 comprises a bottom stop pad 32, back stop pad 33, transfer or stop block 34 which serves as a bridging member fastened toa pivoted arm 35, top stop pad 36, and stop bracket 37 mounted on the stop bar 15.
  • the bracket 37 also is bolted to the blanket segment 11.
  • a connecting rod 38 is pivotally connected at 39 to the pivoted arm 35, and at its opposite end is pivotally connected at 40 to a bearing housing actuator arm 41.
  • the arm 41 is mounted on a needle bearing 42 (FIG. 4). This mounting permits trigger motion to be transmitted from a trigger 43 to the bridging member or stop block 34, as will be more fully explained in the description of the operation of the machine.
  • a spring 44 and bracket 45 hold the bridging member or stop block 34 in the position shown in FIG. 1 until such time as a malfunction signal causes'the triggerto skip-print.
  • Any conventional malfunction signal (not shown) actuates an air cylinder 50 and air cylinder piston rod 51 or other suitable actuating means.
  • the rod 51 normally is retracted but is moved to extended position when the air cylinder responds to the malfunction signal, thereby moving the cam follower holder 52 outwardly, which causes the cam follower 53 to intersect the path of the trigger 43 to actuate the trigger to move from the position of FIG. 1 to that of FIG. 2.
  • the cam follower holder pivot pin 54 mounts the holder'on the block 55.
  • the normal operation of the printer is as follows:
  • the printer drum 10 with blanket holder segments 11 thereon rotates continuously, and in this embodiment is shown as rotating counter clockwise.
  • the cam ring 26, with cam working area 25 thereon, is stationary.
  • the working area 25 of the cam is opposite the mandrel wheel 60 which carries containers 61, or other objects to be printed, as shown in FIG. 1.
  • the mandrel wheel 60 is geared to the blanket holder segment drum to rotate continuously to carry the containers 61 past the blanket segments 12.
  • the blanket holder segments 11 are carried with the drum 10 to successively pass in an arcuate path between the rotating mandrel wheel 60 and the cam surface 25 of the stationary ring 26.
  • the periphery of the mandrel and of the blanket segments do not intersect.
  • This movement of the drum and blanket holder segments mounted thereon causes the cam follower 23 to move onto the outwardly extending working area 25 of the cam into the operative position, as shown in FIG. 1, where it is ready to transmit radially outward movement to the blanket holder segment 11 into printing position.
  • This radially outward movement is transmitted by the cam follower 23 through the bottom stop pad 32, bridging member 34, top stop pad 36, and stop bracket 37, to the blanket holder segment 11, to thereby produce pivotal movement of the segment about the pivot shaft 13, resulting in movement of the blanket 12 into printing contact with the articles 61 on mandrel wheel 60.
  • This is the normal operation of the printer during which time the bridging member 34 closes the gap between the bottom stop pad 32 and top stop pad 36.
  • the bridging member 34 and .the pivoted arm 35 on which it is mounted are held in the closed gap" position by the spring 44 and bracket 45 at all times during the printing operation.
  • a signal is con- .veyed to the air cylinder 50, to move the rod 51 to extended position, thus moving the cam follower holder 52 outwardly and causing the cam follower 53 to contact the trigger 43, as shown in FIG. 2.
  • the trigger 43 is fastened to the bearing housing actuator arm 41, which has pivotally connected thereto the end 40 of the connecting rod 38. Movement of the trigger thus imparts a pulling motion to the rod 38 which in turn pivotally moves the arm 35 and bridging member 34 from the position of FIG. 1 to that of FIG.
  • the bridging member 34 is automatically reinserted between the pads 32 and 36 to bridge the gap and to restore the operative connection between the cam follower 23 and the blanket holder segment 11, whereupon normal printing function of the successively actuated blanket segments is restored.
  • the parts may be of relatively light mass and therefore capable of more rapid operation, in excess of 1,000 containers per minute, than has been practical in prior art operations.
  • a printer and skip-print mechanism for printing articles carried on a rotated wheel comprising a. a plurality of blanket holder segments mounted on a rotated drum successively movable to printing position relatively to articles to be printed,
  • operative connections including a withdrawable bridge member between each cam follower and blanket holder segment for moving the segment into printing position, and
  • skip-print means responsive to a malfunction signal operatively connected to said withdrawable bridge member for withdrawing the bridge member from said operative connections between the cam follower and segment and thereby preventing movement of the segment into printing position when malfunction occurs.
  • the skip-print means includes a trigger on each blanket holder segment, and a connecting rod operatively connected to the trigger and to said operative connections between the cam follower and blanket holder segment.
  • each cam follower and blanket holder segment comprise a bottom stop pad and a top stop pad between which the bridge member is loosely located, a pivotally mounted bridge member arm, and spring means holding said am and bridge member in motion transmitting position between said stop pads.
  • the skip-print means comprises a reciprocable rod responsive to a malfunction signal, a pivotally mounted trigger on each blanket holder segment, trigger contacting means movable by the rod to intersect the path of the trigger, and operative means between the trigger and the bridge member for withdrawing the bridge member from the operative connections between the cam follower and segment.
  • the operative means between the trigger and the bridge member comprise a bearing housing arm connected to. the trigger, a connecting rod having one end pivotally connected to the bearing housing arm and its other end pivotally connected to the bridge member arm.
  • a printer and skip-print mechanism for printing articles carried on a rotated wheel comprising a. a plurality of blanket holder segments mounted on arotated drum successively movable to printing position relatively to articles on the wheel,
  • operative connections including a withdrawable bridge member between each cam follower and blanket holder segment for moving the segment into printing position
  • trigger operated skip-print means responsive to a malfunction signal operatively connected to said withdrawable bridge member for withdrawing the bridge member and producing a gap in the operative connections between the cam follower and segment and thereby preventing transmission of movement from the cam follower to the segment.
  • a printer and skip-print mechanism comprising a. a plurality of blanket holder segments mounted on a rotated support,
  • skip-print mechanism responsive to a malfunction signal including a bridge member which is withdrawable from the means successively moving the segments into printing position, whereby movement of the segments into printing position is prevented when malfunction occurs
