Definitions

  • the invention relates to a carrier shaft for receiving the winding cores of cloth rolls.
  • the invention relates to the storage of cleaning cloth rolls in offset printing machines.
  • Cleaning cloth rolls are usually wound on a core in the form of a sleeve made of cardboard, plastic or metal.
  • the sleeves are pushed onto support shafts and fixed axially and in the direction of rotation for the time until the wound-up cloth stock is consumed.
  • the empty sleeve is removed and a new roll of cloth is pushed onto the shaft.
  • the roll change requires the aid of tools to remove the empty shell and, if necessary, to place a new roll in position.
  • the invention has for its object to provide a receptacle for a cloth roll of the type mentioned, which allows a roll change without the use of tools.
  • the carrier shaft according to the invention is characterized in that it has at one end to the shaft end conically widening head piece with non-round cross-section and that at the other end a tool-free detachable tail is provided.
  • the assembly of a roller on the carrier shaft is effected in that the carrier shaft is inserted into the winding core sleeve or this is pushed onto the carrier shaft.
  • the detachable end piece is removed.
  • the carrier shaft enters the winding core sleeve until the outwardly flared head reaches the end of the sleeve. Since the head widens conically towards the end of the shaft and otherwise out of round, for example polygonal, the shaft jammed in the sleeve or the sleeve on the shaft.
  • the non-circular shape of the head piece ensures that the sleeve is held against rotation on the shaft.
  • a non-circular shape here means, in particular, that the head piece has a polygonal, for example square or hexagonal cross section or a cross section provided with sharp-edged ribs.
  • the cross section is formed so that the sleeve is fixed against rotation on the shaft. The sleeve can therefore optionally be driven or braked.
  • the releasable end piece at the other end of the shaft preferably has a ball detent mechanism whose spring-biased balls on the one hand enable locking of the tail, but on the other hand can be relieved from the spring preload to release the tail by means of a handle.
  • Both the head piece and the end piece have an annular projecting shoulder, which serves as an axial stop for the cloth rolls.
  • a cloth roll 10 is wound, for example, on a winding core sleeve 12 in the form of a cardboard tube.
  • the winding core sleeve 12 is received by a carrier shaft 14.
  • the support shaft 14 is formed in the central region by a tube 16, in particular made of steel, at its right end in Fig. 2, a head piece 18 is attached and merges on the left side in Fig. 2 in a shaft portion 20, on which a sleeve-shaped End piece 22 is releasably attached.
  • a shank portion 24 of smaller diameter on which the sleeve-shaped end piece 22 can be pushed and on which this is latched, as will be explained below.
  • the tail has in the area outside the cloth roll 10 on a radially projecting, a shoulder 26 forming annular portion 28 which serves as a stop for the cloth roll 10 and holds it to the left in the axial direction.
  • resiliently biased detent balls 30 are indicated by dashed lines in the rest. These attach the end piece 22 on the shaft portion 24. From the shaft portion 24 occurs in the axial direction of a push rod 32 with a knob 34 at its end. The push rod 32 can be pressed in the axial direction in the shaft portion 24 to the right in Fig. 2 and thereby releases the spring bias of the locking balls 30, so that the sleeve-shaped end piece 22 can be removed. In this way, the cloth roll can be pushed down to the left in Fig. 2 of the support shaft 14 and the support shaft to the right in Fig. 2 are pulled out of the cloth roll.
  • the head piece has, within the end of the winding core sleeve 16, a wedge section 36 which has a non-circular, in particular polygonal, cross-section in the illustrated example.
  • This wedge portion is provided with sharp corners and incidentally in the interior of the sleeve 16 in conical together. Due to the conical shape and the sharp-edged corners is achieved that the head piece with the wedge portion 36 when pulling in from the right into the winding core sleeve anchored here in the direction of rotation, for example, cuts into the cardboard tube.
  • the cross section of the wedge portion 36 need not be square. It also does not have to be a uniform polygon.
  • an outwardly projecting annular portion 38 which corresponds to the annular portion 28 at the other end and serves as an axial stop for the cloth roll.
  • the carrier shaft terminates in a short axle 40th
