  • the gripper member is slidably positioned on the lever and a spring between the bracket and gripper member end portion urges the gripper finger against the gripper pad.
  • This invention relates to a sheet gripping device and more particularly to a sheet gripping device where, on opening and closing, the gripper finger follows a path controlled by the cam surfaces.
  • the conventional sheet gripping devices include gripper fingers that are nonrotatably secured to a gripper shaft.
  • the gripper fingers are moved toward and away from the gripper pad by rotating the gripper shaft.
  • the gripper fingers follow a circular path because of their direct connection to a rotatable gripper shaft that is fixed within the cylinder.
  • United States Pats. 703,605; 1,275,002; 2,599,776; 2,775,197 and 3,151,552 disclose gripper devices that follow a circular path.
  • the invention is directed to a gripper device that moves perpendicular to the gripper pad upon closing and eliminates sheet movement upon engagement of the sheet between the grpper finger and pad.
  • the gripper device permits a narrow cylinder gap so that the diameter of the cylinder and the press size can be reduced substantially.
  • the sheet gripper device includes a gripper assembly and means to open and close the gripper device.
  • the gripper assembly includes a lever having a bracket member extending laterally therefrom. The lever is nonrotatably secured at one end to a gripper shaft.
  • a gripper member is slidably positioned on the lever and movable longitudinally relative thereto.

  • the cam surface preferably has a configuration to move the gripper finger perpendicular to the outer surface of the gripper pad as the gripper finger closes against the gripper pad. With this arrangement, the gripper finger is moving perpendicular to the edge of the sheet as it is engaging the sheet between the gripper finger and gripper pad.
  • This provides a final closing motion on the sheet that is perpendicular to the gripper pad and does not move the sheet of varying thickness along the cylinder upon closing and thereby, maintains registry.
  • the cam configuration for moving the gripper member permits the longitudinal gap in the cylinder especially adjacent the external surface of the cylinder to be maintained as a relatively narrow gap so that it is possible to reduce both the cylinder diameter and the overall press size.
  • the principal object of this invention is to provide a sheet gripping device that requires a relatively narrow gap or opening in the cylinder periphery.
  • Another object of this invention is to provide a sheet gripping device wherein the gripper finger moves perpendicular to the sheet and gripper pad upon closing so that the gripper does not impart motion to the sheet on the cylinder during engagement of the sheet by the gripper.
  • FIG. 1 is a fragmentary plan view of a cylinder with the improved sheet gripping device positioned therein.

  • the cylinder 10 is rotatably supported on an axial shaft 24 in press frame member (not shown). Suitable driving means are provided to rotate the cylinder 10'.
  • a cam member 26 is fixedly positioned relative to the cylinder 10 and has a cam surface 28. The cam '26, with the cam surface 28 opens and closes the grippers in timed relation at preselected angular positions of the cylinder 10.
  • the cylinder longitudinal recessed portion .12 has a plurality of bearings 30 secured therein by means of screws 32.
  • the bearings 30 have an upwardly extending portion 34 with a bore 36 therein.
  • An intermediate shaft 38 is rotatably supported in the bearings 30 and is positioned parallel to the axis of the cylinder 10.

  • a link member 40 is nonrotatably journaled at one end on the shaft 3-8 by a key 41 (FIG. 1) and extends laterally therefrom.
  • a gripper shaft 42 is rotatably journaled in the other end of link member 40 and is pivotally movable about the axis of the intermediate shaft 38 by link member 40.
  • a cam follower 44 is nonrotatably journaled at one end of intermediate shaft 38 by a key 45 and has a cam roller 46 rotatably positioned on the other end.
  • the cam roller 46 is urged into abutting relation with the cam surface 28 of cam member 26 by a spring member 48.
  • the arrangement of the spring member 48- to urge the cam roller 46 against the cam surface 28 is illustrative only and other means for urging the cam roller 46 against the cam surface 28 may be employed.
  • the cam follower 44 rotates with the cylinder 10 and the cam roller rides on the fixed cam surface 28.
  • the configuration of the cam surface 28 is such that the cam follower 44 pivots the link 40 about the intermediate shaft 38 at preselected angular positions of the cylinder 10 to thereby open and close the grippers at preselected angular positions of the cylinder 10'.
  • the end portion of cylinder 10' has a cam bracket 50 secured thereto by means of bolts 52.
  • the cam bracket 50 extends across the gap 16 and has a cam surface generally designated by the numeral 54 that extends angularly to the cylinder periphery 18.
  • the cam surface 54 has a first portion 56 and a second portion 57. The particular configuration of the cam surface '54 will be discussed in detail hereafter.

  • the cam roller 60 is urged against the cam surface 54- by means of the spring 62 that is secured by a pin 64 to the end portion of cylinder 10.
  • the spring 62 as a means for urging the cam roller 60 against the cam surface 54 is for illustrative purposes only and other suitable means may be employed.
  • the oscillation of the cam follower 44 by the cam surface 28, upon rotation of cylinder 1.0 Will oscillate or rotate the link 40 about the axis of intermediate shaft 38- to thereby axially displace the gripper shaft 42 relative to the axis of the cylinder 10.
  • the axial displacement of the gripper shaft 42 will move the cam roller 60 along the cam surface 54 so that the cam follower 58 will impart rotation to the gripper shaft 42 when the cam follower roller is displaced angularly thereto by means of the cam surface 57 as will be later explained.
  • the link 40 is, therefore, arranged to rotate gripper shaft 42 about the axis of intermediate shaft 3 8 and the cam surface '54 is arranged to rotate the cam follower 58 about the axis of the gripper shaft 42.
  • a plurality of link members 40 and bearing members 30 may be positioned within the recess 12 to suitably support the intermediate shaft 38 and gripper shaft 42 as is illustratively shown in FIG. 1.
  • a second cam bracket 50 on the opposite side of the cylinder 10 with a similar cam surface 54 and a cam follower 58 nonrotatably connected to the opposite end of the gripper shaft 42.
  • a plurality of gripper assemblies generally designated by the numeral 70 and illustrated in detail in FIG. 5 are nonrotatably secured to the gripper shaft 42 by means of keys 72.
  • the gripper assemblies 70 include a ways lever 74 that has an end portion. nonrotatably secured to the gripper shaft 42 and a gib bracket 76 secured to a side portion thereof.
  • a gripper member 78 has a laterally extending gripper finger 80 with a surface 82 that is arranged to abut the surface 22 of the gripper pad 20.
  • the gripper pad 20, although secured to the cylinder 10, will for convenience be referred to as a portion of the gripper assembly.
  • the gripper member 78 has a laterally extending other end portion 84 with a longitudinal bore 86 therein and a spaced parallel laterally extending portion 88 with a longitudinal threaded bore 90 therein.
  • An adjusting screw 92 is threadedly positioned in the threaded bore 90.
  • the gripper member 78 is slidably positioned in the ways lever 74 and is arranged to move longitudinally relative thereto.
  • a shaft member 94 is secured to the bracket 76 and extends into the bore 86 of the gripper member laterally extending end portion 84.
  • a spring 96 urges the gripper member end portion 84 away from the bracket member 76 and urges the gripper finger 80 into abutting relation with the gripper pad 20.
  • the adjusting screw 92 is arranged to provide the clearance between the top of the bracket 76 and the gripper member laterally extending portion] 88.
  • the arcuate displacement of the gripper shaft 42 relative to the intermediate shaft 38 will first move the ways lever 74 relative to the gripper member 78 until the adjusting screw 92 abuts the surface of bracket 76. Further arcuate vertical displacement of the gripper shaft 42 will move the gripper finger 80 away from the gripper pad 20.
  • the cam surface 54 guides and controls the relative movement of the cam finger surface 82 relative to the surface 22 of gripper pad 20.
  • gripper finger surface '82 is urged against the surface 22 of the gripper pad 20 and engages an edge of sheet S therebetween. This is the closed position of the gripper assembly 70.
  • Rotation of the cylinder relative to the fixed cam 26 moves the cam roller 46 of cam follower 44 along the cam surface 28.
  • the cam surface 28 has such a profile that a recessed portion pivots the cam follower 44 about shaft 38 in a counter-clockwise relation because the cam roller 46 is continually urged against the cam surface 28 by the spring 48. This part of the profile of the cam 26 functions to open the gripper assembly 70.
  • the rotation of the cam follower 44 in a counterclockwise direction transmits the rotation to intermediate shaft 38 which, in turn, rotates the link member 40 in the same counter-clockwise direction.
  • the link member 40 is rotatably secured to the gripper shaft 42 and moves the gripper shaft axially in the same counter-clockwise direction as the link 40 but because of the rotatable connection between gripper shaft 42 and the link 40, the link permits the gripper shaft 42 to rotate about its own axis as it pivots about shaft 38.
  • the link member 40 functions to displace the gripper shaft 42 axially relative to the axis of cylinder 10.
  • the cam follower 58 is nonrotatably secured to the gripper shaft 42 and is also axially displaced with the gripper shaft 42 upon counter-clockwise movement of the link member 40. Initial axial displacement of the link 40 moves the gripper shaft 42 upwardly and in turn moves the ways lever 74 relative to the gripper member 78 until the adjusting screw 92 abuts the upper portion. of bracket member '60.
  • Both the cam follower 58 and the gripper assemblies 70 are nonrotatably secured to the gripper shaft 42 by means of the key members 59 and 72 respectively.
  • the cam roller 60 of cam follower 58 is constrained to move according to the profile of the cam surface 57 to thus limit the axial rotation of the gripper shaft 42 so that the first movement of the gripper finger 80 is substantially perpendicular to the surface 18 of cylinder 10.
  • the initial movement of the cam follower 58 and the gripper finger 80 is illustrated in FIG. v3 where the gripper finger surface 82 is substantially parallel to the surface 22 of gripper pad 20.
  • the initial opening movement of the gripper finger 80 is in a direction perpendicular to the surface of pad 20.
  • cam follower 44 Further rotation of the link 40 by cam follower 44 displaces the gripper shaft to the position illustrated in FIG. 4.
  • the cam roller 60 of cam follower 58 has moved up onto another part of the profile of the cam surface 57.
  • the movement of cam roller 60 along cam surface 57 rotates the cam follower 58 and the gripper shaft 42 nonrotatably secured thereto to the position illustrated in FIG. 4.
  • the cam followed 58 rotates both the gripper shaft 42 and the gripper assembly 70 nonrotatably secured thereto until the gripper finger 80 is moved to the completely open position such as illustrated in FIG. 4.
  • the cam follower 46 In closing the gripper finger 80 on the pad 20, the cam follower 46 is urged upwardly by a portion of the cam surface 28 to pivot the cam follower 44 in a clockwise direction.
  • the link member '40 also pivots with the intermediate shaft 38 in a clockwise direction to axially displace the gripper shaft 42 toward the axis of cylinder 10.
  • the downward clockwise axial displacement of gripper shaft 42 moves the cam roller 60 of cam follower 58 along the portion 57 of the cam surface 54 to move the gripper finger 80 toward the gripper pad 20.
  • the cam surface '56 of cam '54 has moved the cam follower into a position substantially perpendicular to the surface of the cylinder thereabove.
  • the under surface 82 of gripper finger 80 is positioned directly above the surface 22 of pad and is spaced therefrom with an edge of sheet S therebetween.
  • the gripper finger surface 82 has not as yet engaged the edge of sheet S to the surface 22 of the pad 20. Further rotation of link by the cam member 26 moves the gripper shaft 42 downwardly toward the axis of cylinder 10.
  • the cam follower '58 that controls the direction of movement of gripper finger has the cam roller 60 positioned on the vertical portion 56 of cam 54 so that upon downward movement of the gripper shaft 42, the gripper finger 80 is moved downwardly in a direction perpendicular to the surface of cylinder surface 18 to engage the edge of sheet S between the surfaces 82 and 22. Further movement of the gripper shaft 42 moves the ways lever 74 relative to the gripper member 78 to exert a compressive force on spring 94 and forcibly engage the sheet S between the gripper finger 80 and pad 20.
  • the last closing movement of the gripper finger 80 against the gripper pad 20 is in a direction perpendicular to the surface of gripper pad 20 so that there is no relative circumferential movement or displacement of the sheet on the cylinder surface 18 by the final closing movement of the gripper 80 as is present 'where the gripper finger 80 follows a circular path about the axis of the gripper shaft.
  • the path followed by the gripper finger 80 is defined by the profile of the cam surface 54. With this arrangement it is possible to have the cam finger 80 follow substantially any preselected path as defined by the cam surface 54.
  • One of the advantageous features of the above described gripper device is the perpendicular movement of the gripper finger surface 82 relative to the pad 20 through a substantial distance upon closing. The gripper device is thus versatile in that it can be utilized with papers of different thickness without the gripper finger 80 displacing the sheet along the surface of the cylinder 80'.
  • Another advantageous. feature of the sheet gripper device is the relatively narrow gap required for the gripper assemblies. The gap 16 illustrated in the drawings, is controlled by the desired movement of the gripper finger 82. As illustrated in FIG.
  • the gripper 78 is in a fully opened position. If it were desired to reduce the gap 16 further, the cam surface 54 could be modified to move the gripper finger 80 in a less arcuate path upon completely opening. With this arrangement it is possible to have the gripper finger 82 move to a completely open position and remain substantially perpendicular to the surface 18 of the cylinder and thus reduce the gap 16 to a width slightly larger than the gripper member 78 adjacent the finger 80.
