Definitions

  • ABSTRACT A conveyor chain in the form of a roller chain guided [21] PP N03 3971790 between spaced longitudinal guide members presenting flat land surfaces lying in a vertical plane at the [30] Foreign Application priority Data fdge the chain. Certain ones of the pins 031L116 rol- 2 I 224 er c am, 1n a repet1t1ve pattern, are exten e outscpt Gummy 6061 wardly of the land surfaces.
  • conveyor chains are provided as a laterally spaced pair with gripper mechanisms carried bridgingly between them.
  • the chains are guided in trackways which must be lubricated. Because the abrasive dust. paper particles and the powder used to prevent offsetting the printed impressions from one sheet to another. the surfaces quickly become coated with a gummy accumulation which is difficult to remove and which tends to destroy the effect of the lubricant and thus shorten the life of the chains and trackways. More over. the lubricant from the chains often is thrown upon the sheets being transported requiring that the soiled sheets be discarded.
  • an object of the present invention to provide a conveyor chain construction which has novel sealing means for operation in a contaminated environment such as that to be found about conveying and delivery mechanism of a printing press. It is a general object to provide a conveyor chain construction in which the chain and its guideways are sealed against entry of foreign matter and sealed against escape of lubricant so that the moving parts are protected against the effect of abrasive materials and the lubricant is kept clean and fully effective. It is a related object to provide a conveyor chain construction which is both simple and effective but which reduces maintenance to a minimum. avoiding necessity for frequent cleaning or lubrication and permitting operation at high speed and efficiency over a long period of time. It is. moreover. an object of the invention. when the device is used in a printing press, to prevent the sheets which are being transported from being spotted and soiled by escaping lubricant.
  • FIG. I is a plan view of a section of conveyor chain looking along line 1-1 in FIG. 2, with portions in partial section.
  • FIG. 2 is an elevational view looking along line 22 in FIG. 1.
  • FIG. 3 is a vertical section taken along line 3-3 of FIG. 1.
  • roller chain made up of parallel rows of flat links 11, 12 in overlapping relation. pinned together by pins 13, certain of the pins, 14. being extended laterally away from the chain for a purpose which will shortly appear. lnterposed between the rows of links are rollers or spacers 15. The rollers may have an internally telescoped hardened liner as indicated in cross section at 16.
  • a guide assembly 20 is provided which. as shown in FIG. 3, is preferably in the form of a channel 21 of inverted U-shaped construction secured along one of its walls. by means not shown. to supporting frame structure 22.
  • the member 21 has a downwardly presented edge 23.
  • Supported in opposed. edgewise position is a cooperating guide member 24 having an upwardly facing edge 25.
  • the edges are spaced parallel to one another to form a track or guideway, and are of such width as to mate with. and support. the rollers 15 of the conveyor chain. It will be understood that while the track defined by the edges 23, 25 may have a long. straight run portion. the chain 10 is endless and the track is accordingly curved or looped at its ends (not shown).
  • land surfaces are provided straddling the chain and lying in a vertical plane which extends along the lateral edge of the chain.
  • Carried on the pins of the chain. and along one side of the chain. are overlapping coverplates which ride flatly against the land surfaces and which are cooperatingly recessed in the region of overlap to provide a continuous sealing surface and to permit relative movement. or articulation. as the chain departs from a straight line path.
  • a typical cover plate is shown at 30, formed of a flat layer of metal or plastic. of oval contour. and having pin openings 31, 32 centered within its rounded ends 33. 34.
  • the cover plate has a shallow recess 35 of circular profile at one end and a similar shallow circular recess 36 at the opposite end, the two recesses being oppositely faced.
  • the plate presents a flat inwardly facing surface 37.
  • cover plate 40 which may be of the same or different length. It will be seen that this plate has spaced openings 41, 42 for mounting purposes with rounded ends 43, 44 formed with shallow circular recesses 45, 46 and having a flat inwardly facing surface 47.
  • flat land surfaces 51, 52 are provided extending along the edge of the chain in straddling relation. Such surfaces are formed on members 53. 54 which may be secured by welding or the like to the respective guide members 21. 24.
  • the land surfaces 51. 52 are alined with one another in the same plane. a plane which is slightly offset from the chain body as shown in FIG. 3. Because the recessing of the adjacent cover plates. the cover plates cooperate to provide a continuous sealing engagement with the land surfaces.
  • Means are preferably provided for causing the cover plates to bear resiliently against the land surfaces; for example. a coil spring 55 may be used (FIG. 1) seating against a bushing 56 which is tele scoped into the alined plate openings.
  • a roller chain having parallel rows of flat links and having 5 pins for pinning the links in overlapping relation with rollers interposed between them.
  • the rollers being of lesser dimension so as to define a longitudinally extending groove on each side of the chain.
  • parallel guide members enclosing the chain and extending longitudinally of the chain on both sides thereof, the guide members presenting edges registering with the grooves and engaging the rollers to provide a lubricated guideway for the chain, the guide members having flat closely spaced land surfaces straddling the chain and lying in a plane close to the chain which extends perpendicularly to the roller axes along one side of the chain.
  • each covering plate having a pair of holes engaged by an adjacent pair of pins. the covering plates being in longitudinally overlapping relation and sufficiently wide as to bear upon both of the land surfaces so as to seal the chain and lubricated guideway against entry of foreign matter and against escape of the lubricant.
