Definitions

  • the invention relates to a mandrel for grasping and fixing a roll of printing material web wound on a sleeve, which can be moved axially in a support arm of a roll changer by means of a drive device, with a cylindrical mandrel body and a frustoconical mandrel tip.
  • a generic mandrel is known from DE-PS 40 13 092.
  • support arms are rotatably mounted on a supporting axis.
  • Rotatably driven, structurally identical mandrels are arranged at the respective end of each of the support arms.
  • a printing material web roll wound on a sleeve can be clamped between two axially identical mandrels.
  • the mandrels are each connected to a drive device, which is also arranged at the respective end of the support arms and by means of which the mandrel connected to it can both be rotated and moved in the axial direction.
  • the printing material web roll which is transported to the roll changer by means of an automatic transport system or by any other means of transport, is generally brought into a loading position with a lifting device, which can also be installed on the transport system or means of transport, which is determined by the fact that the printing material web roll is roughly aligned between the axes the appropriate mandrels are held.
  • a lifting device which can also be installed on the transport system or means of transport, which is determined by the fact that the printing material web roll is roughly aligned between the axes the appropriate mandrels are held.
  • various setting tolerances add up, such as deviations in the geometric properties of the printing material web roll from the ideal values, so that the cross-sectional circle of the sleeve is not exactly concentric with the cross-sectional circle of the roll, or positional deviations of the automatic transport system which result in deviations in the loading position.
  • a possible solution to this problem would be a photoelectric barrier measurement through the sleeve prior to the detection of the roll.
  • this represents an indirect measurement, an additional measuring position is required into which the automatic transport system or the lifting device must travel. This is an additional source of error.
  • tests have shown that such a measurement is too imprecise for the axis-correct accommodation of the sleeve, since scattering of the light beam, which is particularly troublesome when different widths of the printing material web rolls occur, is inevitable.
  • the object of the invention is therefore to provide a mandrel for detecting a roll of printing material web wound on a sleeve with simple means so that directly during the loading process a non-destructive detection of the case in which the roll is not picked up at all or without damaging the edges of the sleeve is not possible, is given and that at the same time an error message can be derived from a control panel.
  • the mechanically actuated probe and the electrical switch integrated in it which activates an electrical circuit when the probe is actuated, it is possible to reliably detect an error in the loading position of the roll regardless of the strength of the pressing force of the mandrels and to switch it off quickly, or to reverse the forward movement of the mandrels, so that damage to the sleeve and paper roll to be accommodated is excluded.
  • the mandrel designated as a whole by 1, comprises, in the manner shown, a cylindrical mandrel body 2 and a frustoconical mandrel tip 3.
  • the mandrel body 2 has a plurality of expanding jaws 4, which are used in a manner known per se for clamping the mandrel 1 in a sleeve 5 of a printing material web roll .
  • the entire mandrel 1 can be moved axially by a scraper ring 6, which also serves as a limiting element, the functioning of which is also known and is not the subject of the invention.
  • the mandrel tip 3 is shown in cross section. It has a concentric recess 7.
  • this recess 7 is the probe in the form of a bolt 8, which on the one hand protrudes by a definable amount a from the end face 9 of the mandrel tip 3 and on the other hand by means of a compression spring 10, which helically surrounds a stepped part 11 of the bolt 8, against the bottom 12 the recess 7 is supported in the manner shown, inserted axially.
  • the bolt 8 is biased against the compression spring 10 by means of a socket head screw 13 which passes axially through the bolt 8 and can be screwed through the bottom 12 of the recess 7 into the mandrel body 2.
  • this cap screw 13 allows the amount a by which the bolt 8 protrudes from the end face 9 of the mandrel tip 3 to be set.
  • the cheese head screw 13 is screwed against an adjustable stop in a known manner and therefore not shown, so that the dimension a can be reached easily and in a defined manner.
  • the bolt 8 in turn has a cylindrical recess 14 which is open on the side of the bolt 8 opposite the base 12.
  • the electrical switch protrudes into this recess 14 in the form of a pin switch 15 which can be moved in the longitudinal direction of the recess 14.
  • the pin switch 15 is spaced on the one hand by a compression spring 16 from the bottom 17 of the recess 14 and on the other hand in connection with the open contacts 18, 19 of an electrical circuit 20 can be brought.
  • the electrical contacts 18, 19 are designed in the form of two annular contacts which are arranged concentrically with one another in the bottom 12 of the recess 7 of the mandrel tip 3.
  • the pin switch 15 can be restricted in its movement by means of a pin 21 which can be inserted into the bolt 8 and which can be brought into a notch 22 in the pin switch 15 and is thus secured against falling out of the recess 14.
  • the circuit 20 is guided through the mandrel body 2 to a drive device for the mandrel 1, not shown.
  • the drive device interacts in a known manner with a signal transmitter, not shown, so that an error message can be issued to a control panel when the drive direction is reversed.
  • mandrel tip 3 in the area of its end face 9 and the bolt 8 as part of the probe in the area protruding from the end face 9 are shaped such that no edges occur.
  • the printing material web roll is in the drawing in the loading position, but its sleeve 5 is not in the axially correct position, so that the bolt 8 in the recess 7 of the mandrel tip 3 when trying to accommodate the sleeve 5 against drives the edge of the same.
  • the bolt 8 is pressed against the compression spring 12 and takes the pin switch 15, so that it bridges the contacts 18, 19.
  • the now closed circuit 20 causes the drive device for the axial movement of the mandrel 1 to reverse its drive direction and at the same time the signal generator to issue an error message to a control panel so that an operator is alerted to align the sleeve 5 so that the sleeve is damaged 5 is completely excluded.
  • the mandrel tip 3 is equipped with a cone angle, in which the sleeve 5 can slide relatively easily and without damage to the mandrels 1, in the event that the axis deviation from the axially correct loading position is within a tolerance range in which the probe 8 is completely with it the axis 5 facing side can look into the opening of the sleeve 5.
