Definitions

  • the invention relates to a cylinder in a folder, i.e. a collection or Folding cylinder, with at least one axially displaceable for a production changeover Cam.
  • a generic folding cylinder is known from DE 4 426 504 A1.
  • Here forms a Cam two control cams by axial displacement of the cam optionally interact with a cam roller and the movement of jaws Taxes.
  • the guide bolts are made by means of additional drive means postponed.
  • the guide bolts are with the cam to be moved screwed.
  • This solution has the disadvantage that the guide bolts do not are guided free of play, which means that when the cam rollers roll on the cam Line contact of the guide bolts occurs in the guide holes on the frame. which leads to the well-known formation of rust in the area of contact. This promotes the Wear and also contributes to increased noise
  • the object of the invention is to provide a reversible cylinder for a folder create that with simple technical means and small space requirement in axial Direction of the cylinder from one type of production of the folder to the other is reversible.
  • a guide means which is axially displaceable relative to the cylinder engages in the manner of a claw in a recess, which is also opposite the Cylinder axially slidably mounted cam or one axially slidable mounted socket on which the cam is seated is formed.
  • the socket becomes a recess in the cylinder axis direction on both sides or the cam disc is carried along by the guide means and thus optionally axially or moved here.
  • the cam disc is preferably axially fixed in its displacement positions. In the fixed displacement positions, the guide means no longer touches the side walls the recess against which it previously pressed for the purpose of moving.
  • the guide means is preferably itself axially by means of an axially displaceable piston postponed.
  • the piston is and is axially guided in a machine-fixed cylinder space on its front and underside optionally with a pressure medium, preferably Compressed air, can be acted upon
  • the guide means has a simple one Bolt on, of which facing the recess on the socket or the cam An engaging part ends at an angle in the form of a hook or claw sticking out.
  • this pin is on an end face of the drive piston attached, preferably a disk forming the drive piston is simply on this Screwed on the end of the guide bolt or suitably rigidly attached to it.
  • the camp for the drive piston i.e. the cylinder walls surrounding the piston and their end faces
  • the storage for the guide means forms a conclusion.
  • An additional Storage is not required, but could be provided.
  • the Cylinder space for the drive piston is particularly space-saving in a bearing bush for the Folding cylinders must be excluded.

  • the two cams 9 and 10 are seated in turn, side by side firmly on a common, flange-shaped socket 11.
  • Die Bushing 11 is rotationally fixed on a bush-shaped driver 18, but in the cylinder axis direction slidably mounted.
  • the driver 18 is in turn on the shaft journal 22 rotatably mounted.
  • the Driver 18 At its outer end seen from the collecting cylinder 1 is the Driver 18 rigidly connected to a gear 21.
  • Driver 18 driven independently of the rotational movement of the collecting cylinder 1
  • a disc is placed on the front, one Stop for the bushing 11 forms during its axial displacement.
  • Each of the cams 9 and 10 is provided with two control cams, one for collective and the other for single production.
  • By axially moving the cams 9 and 10 is optionally one of the two control cams of each cam in operative connection brought to the respective cam roller.
  • any of the Control cams can be provided on a separate cam, or it can all four control cams sit on a single cam.
  • Control curves for the same cam roller conceptually combined to form a "cam disc”.
  • Cam discs and bushing 11 could also be formed in one piece.
  • the collecting cylinder 1 is in the known manner in at the outer end of its shaft journal 22 a bearing bush 19 of a machine frame 22 rotatably mounted.
  • the driver 18 can also turn relative to the bearing bush 19. For this, it is either sliding rotatably supported in the bearing bush 19 or has an inner peripheral surface of the Bearing bush 19 on a distance.
  • the axial displacement of the bush 11 and thus the two cams 9 and 10 is by means of a guide pin 16 which is displaceable in the cylinder axis direction in the Bearing bush 19 is stored.
  • the displacement movement of the guide pin 16 is by causes a piston 17 in a recessed in the cylinder liner 19 cylinder space is axially displaceable.
  • Several guide pins 16 are on the circumference of the Shaft journal 22 arranged evenly distributed; in the exemplary embodiment there are three such guide pin 16.
  • the guide pin 16 each protrude at right angles to one End of the piston 17 away from this piston 17 directly to the opposite Front of the socket 11 to. From its end facing the socket 11 protrudes from everyone the guide pin 16 from the cylinder axis into the engaging part 15.
  • the engagement parts 15 can be designed as sliders or as rollers with perpendicular to the cylinder axis pointing axes of rotation.
  • the guide pins 16 grip with their guide parts 15 claw-like in recesses on an outer peripheral surface of a flank of the flange-like bushings 11 are excluded.
  • Such a recess can advantageously However, it does not have to be designed as a circumferential guide groove.
  • the recess or the recesses are axially delimited on both sides by side walls 11 'and 12', against which the engaging parts 15 of the guide pin 16 during their axial displacement press and thereby also push the bushing 11 in the desired direction.
  • the recess is purely form-fitting.
  • the engaging parts 15 are preferably even in the cylinder axis direction slightly narrower than the recess or recesses.
  • the recess on the socket side is simply formed by that the flange flank of the bushing 11 is turned off at its outer peripheral edge and then a disk 12 projecting over the circumferential side of the turned-off flange flank the end face of the flange side of the bushing 11 is screwed on.
  • the recess or However, recesses can also be made differently and can also be different lie; they must only be accessible from the engaging part 16.
  • Each of the guide pins 16 can be rigid with a simple cylindrical piston 17 be connected. Basically, a single guide pin 16 with such a is sufficient Piston 17.
  • the drive means 17 is as one only annular piston formed, from the bottom of the several, evenly Guide beams 16 in distributed over the circumference of the shaft journal 22 Protrude cylinder axis direction.
