Definitions

  • the invention relates to a drive for a folding knife-bearing folding knife spindle which is arranged to be movable about its longitudinal axis, in accordance with the preamble of claim 1.
  • a longitudinal folding device for introducing a fold parallel to the paper running direction in which a folding knife rotates in a folding drum and presses the folding products with each rotation of the folding drum between two folding rollers cooperating with the folding knife.
  • the generic US-A-29 19 914 shows a drive for a folding knife spindle.
  • the folding knife spindle can be moved about its longitudinal axis, in which a rotating folding drum having axle journals is mounted.
  • the folding knife spindle also carries a drive gear via which it is driven. The signatures fed between the folding drum and a pair of folding rollers are pressed between rotating folding rollers by the folding knife.
  • a disadvantage of such longitudinal folding devices is that the folding knife has a relatively large amount of play, which leads to inaccurate folding on the printed product.
  • the drive of the Folding knife takes place via a gear, which interacts with a sun gear of the folding knife drum via a planet gear.
  • the invention has for its object to provide a drive for a folding knife with which the folding accuracy can be further increased.
  • the advantages that can be achieved with the invention are, in particular, that the play of the folding knife is almost completely eliminated as a result of the creation of a separate drive train for the folding knife spindle and thus reduced gear pairings and the arrangement of a follower for the gear of the folding knife spindle. This increases the accuracy of the longitudinal fold to be inserted, which also allows a higher folding speed. By overlaying the separate drives for the folding drum and for the folding knife spindle, the installation space required for the folding drum between the side frames is shortened.
  • a folding drum 1 consists of a left and a right side window 2; 3, which in each case on their diametrical sides in the vicinity of the periphery both by a cross member 4 and by a side window fixed rotatable in ball bearings 6; 7 mounted folding knife spindle 8 are connected at a distance which corresponds to the folding drum length.
  • the folding drum 1 is by means of the side windows 2; 3 attached journal 9; 11 and via ball bearings 12; 13 and sockets 14; 16 on both sides in side frames 17; 18 rotatably mounted.
  • the end of the first journal 9 is non-positively or positively with a drive wheel, for. B. a toothed belt pulley 19, z. B. by means of a known double wedge-shaped ring tensioning element 21.
  • annular housing 22 On the circumference of the first side plate 2, in the axial direction to the side frame 17, there is an annular housing 22 which extends coaxially to the journal 9 and which is closed by means of an annular cover 23 in the direction of the journal 9 .
  • the housing 22 accommodates a drive gear 26 rotatably supported on the journal 9 by means of ball bearings 24.
  • the drive gear 26 is with an outside of the housing 22; 23 in the direction of the side frame 17 extending by means of a ball bearing 27 rotatably arranged on the journal 9 drive wheel, z. B. a toothed belt pulley 28, firmly connected.
  • a left journal 29 of the folding knife spindle 8 also projects into the housing 22; 23 and carries a gear 31, which by means of a Key 32 is rotatably connected to the journal 29.
  • the toothed wheel 31 of the folding knife spindle 8 meshes with the drive gear 26 arranged rotatably on the axle journal 9 of the folding drum 1.
  • the folding knife spindle 8 carries a folding knife 33 on one side, which is compensated by a counterweight, not shown. As a result of the reduction in gear pairings to one gear pair 26; 31, the play of the folding knife 33 is reduced.
  • a further reduction in the play of the folding knife 33 can be achieved by assigning a so-called insert 34 to the gear 31.
  • the insert 34 consists of a ring gear, also designated 34, which is arranged with the same outer diameter with the gear 31 frictionally on or next to the gear 31 and which is connected by means of a plate spring-loaded to the journal 29 of the folding knife spindle 8 non-rotatably connected ring flange 36 on the front side of the gear 31 is pressed.
  • the insert 34 has z. B. by a tooth less tooth pitch, so that the gear 31 is always held on bias.
  • a plate spring assembly is designated 37 and is tensioned by means of a washer 41 and a thread located on the journal 29 by means of a shaft nut 42.
  • the housing 22 is by means of its cover 23 and a shaft sealing ring 38 and a spacer 39 against the left journal 9 to protect against Oil leak sealed. Further shaft sealing rings, spacer rings, sealing washers and the like are known and are therefore not described in more detail.
  • the drive of the folding drum 1 takes place via the toothed belt pulley 19, which is arranged on the left axle journal 9 in a rotationally fixed manner, by means of a toothed belt (not shown) at a speed n and driven by the drive gear 26 and 31.
  • the translation of the latter folding knife drive 28, 26, 31 is dimensioned such that the folding knife spindle 8 also performs one revolution per revolution of the folding drum 1.
  • the knife tip of the folding knife 33 moves up and down on a vertical line above the folding rollers.
  • the drive wheel 28, which is firmly connected to the drive gear 26, is outside the side frames 17; 18 arranged (Fig. 2), so that for the drive of the folding drum 1 or the folding knife spindle 8, particularly little space between the side frames 17; 18 needed.
  • the toothed belt pulley 28 is connected to the drive gear 26 in a rotationally fixed manner via a sleeve 43 or hollow connecting shaft which is mounted both on the outside in the side frame 17 and on the inside on the journal 9.
  • the toothed belt pulleys 19; 28 are by means of toothed belts 44; 46 driven. As a result, considerable noise reduction can also be achieved.
