Definitions

  • the invention relates to a web-like material processing machine, in particular a web-fed rotary printing press, with a roller carrier for material rolls which can be accommodated on a pair of mandrels, with a drive motor which can be brought into engagement on the circumference of the material roll feeding the web, preferably having a controllable motor Brake operation switchable belt drive and with a quick stop device assigned to the material roller feeding the web, which can be activated by means of a pulse generator which sets the belt drive to full braking action.
  • each pair of mandrels of the roller carrier is assigned at least one additional brake permanently installed on the roller carrier, the additional brake associated with the pair of mandrels receiving the web of material feeding the web being connectable to the pulse generator by means of an automatic switchover that can be actuated when changing the roller and can be activated by means of the pulse generator together with the belt drive which can be set to full braking operation, and that at least one additional brake provided in the area of a pair of mandrels is designed as a residual roller brake for braking the remaining roller which feeds the run-out path to be cut off when a roll is changed.
  • the belt brake is supported by an additional braking device acting on one or both mandrels.
  • the belt brake can therefore advantageously be dimensioned such that the braking forces transmitted therefrom to the outer circumference of the material roll can also be transmitted correctly and without risk of damage from the paper windings underneath. Since the belt brake goes into full braking effect in the event of danger, the additional brake can advantageously be dimensioned correspondingly weak, which enables the use of one and the same brake as a residual roller brake and as an additional brake.
  • the arrangement according to the invention thus comes out for both purposes with one brake per pair of mandrels, which serves as a residual roller brake when the roll is finished and can be used as an additional brake for the quick stop device in the case of the roll feeding the web.
  • the belt brake also applies the full braking effect in the event of an emergency stop, all the existing brakes are fully effective in the event of an emergency stop. This ensures braking to a standstill within a very short period of time, even at high machine speeds. If a so-called winder is built up in such a case, it is ensured that the winder thickness remains small. This has an advantageous effect not only on safety, but also on user-friendliness, since thin winders are much easier to remove than thick winders and when the machine is restarted, the material web does not have to be completely drawn in again, but only by the Place the winder at the end of the torn web.
  • DE-A 28 55 591 shows a web-like material processing machine with a roller carrier for material rolls that can be received on a pair of mandrels, of which the web of material feeding the web can be braked by means of a control brake in normal operation and, in the event of danger, by means of a quick stop device, which at least can be braked has an additional brake coupled to a mandrel receiving the web of material feeding the web and can be activated by means of a pulse generator.
  • the control brake remains unchanged when the quick stop device is activated.
  • the actual quick stop process is handled solely by the auxiliary brake.
  • the control brake is activated during normal operation and the auxiliary brake when it stops quickly.
  • the consequence of this is that when a quick stop operation is carried out, the entire braking torque or in any case the braking torque which goes beyond the control braking torque runs via the additional brake. It is therefore necessary to dimension this additional brake so strongly that sufficient safety is ensured even under unfavorable conditions. Experience has shown that this leads to a high level of structural complexity and a not inconsiderable space requirement.
  • a further additional brake can be provided in the area of each pair of mandrels. If both mandrels of a pair of mandrels are each coupled to an additional brake, these can advantageously be designed such that approximately the same braking forces are applied, which enables a relatively smooth running even during the braking process.
  • the additional brakes respectively assigned to the material roll feeding the material web can be expediently connected to the pulse generator by means of a switching element which activates the additional brakes assigned to the new role each time the roll is changed. This ensures that when a quick stop operation is initiated, the material roll that is currently in operation for braking is reliably ready for operation.
  • At least one paper tear switch arranged in the region of the web and / or at least one manually operable switch can advantageously be provided as the pulse generator.
  • the hand switch also enables manual intervention by the operating personnel in the event of imminent danger.
  • a printing unit is indicated at 1, to which a paper web 2 is fed continuously.
  • the paper web 2 is drawn off from a roll of material 3, which is received on a roll carrier designated as a whole by 4.
  • the roller carrier is provided with a two-armed rotary star 5.
  • At the end of each arm of the rotary star 5 there is a roll at 3 indicated type recordable, which enables a flying role change.
  • the beginning 6 of the web peeled off from a new roll of the type indicated at 3 is hereby glued to the web 8 peeled off from a finished roll of the type indicated at 7, which is then cut off behind the gluing point.
  • the drawing is based on a situation shortly before this cut.
  • the arms of the rotary star 5 are provided with thorns 9 arranged in pairs, which engage in the sleeves of the material rollers.
  • the respective new roller 3 is accelerated from standstill to operating speed with the aid of a belt drive 10.
  • the belt drive 10 consists of a plurality of belt belts which are arranged next to one another at a distance and are guided over two deflection rollers, one of which is drivingly coupled to a motor 11.
  • the motor 11 can expediently be designed as a DC machine that is easy to control and can be switched from drive to braking operation.
  • the paper web 2 is pulled off the roll 3 by pulling rollers 12.
  • the controlled belt drive 10 can support this pull-off movement or brake the roller 3 slightly to avoid undesired advance.
  • a residual roller brake installed on the arms of the rotating star 5 is used, which will be described in more detail below.
  • the material roll 3 which normally feeds the paper web 2 must be up to within a very short time be braked to a standstill.
  • the belt drive 10 is set to the full braking effect.
  • the DC machine forming the motor assigned to the belt drive 10 can simply be operated in the fourth quadrant.
  • an additional brake 13 is provided in the area of the axis of the material roll 3 to be braked, which is permanently installed on the roller star 5 and cooperates with one of the mandrels 9 assigned to the material roll 3 to be braked.
  • Such an additional brake 13 is permanently installed on the roller star 5 in the area of each pair of mandrels.
  • the additional brake 13 is simply designed as a shoe brake which can be actuated with the aid of an associated electromagnet 14.
  • a brake arrangement of this type is relatively simple and easy to control.
  • a residual roller brake 15 is provided in the region of each pair of mandrels of the roller star 5 on the side opposite the additional brake 13, the operation of which has already been indicated above.
  • an induction brake coupled to an associated mandrel 9 can be used, which enables simple control.
  • the residual roller brake 15 installed in the area of the arm of the roller star 5 that receives the material roll 3 to be braked is used in the exemplary embodiment shown as a second quick stop additional brake.
  • the belt brake which acts on the material roll 3 to be braked is supported by two additional brakes 13 and 15 which act in the region of the mandrels assigned to the roll 3, which enables particularly short braking times.
  • the first auxiliary brake 13 and the residual roller brake 15 used here as the second auxiliary brake are designed for approximately the same braking force.
  • an additional brake it can be operated as a residual roller brake as long as the respectively assigned roll feeds the web 2 as an additional brake assigned to the belt brake and after swiveling the roller star 5 in the position shown in the drawing below
  • the motor 11 assigned to the belt drive 10 and the additional brake arranged on the lower arm of the roller star 5 and operated as a residual roller brake 15 are controlled during normal operation as a function of the web tension, the web speed and the web length.
  • assigned control elements 16 are assigned to the motor 11 or the auxiliary brake operated as a residual roller brake 15, which convert the input signals, determined from the measurement data, into suitable control signals.
  • the measured value input of the control elements 16 is indicated at 17.
  • the measuring elements and transducers are at 18 on the basis of a field potentiometer which interacts with a pendulum roller, at 19 on the basis of a tachometer generator which interacts with a deflection roller and at 20 on the basis of a tensile force meter which interacts with a resiliently mounted deflection roller interpreted.
  • the pulse for triggering the rapid stop process can be superimposed on the measurement signals arriving via the measured value input 17.
  • This is indicated in the drawing by a second input 21 assigned to the control elements 16, which is connected to a hand switch 22 and a plurality of paper tear switches of the type indicated at 23.
  • the paper tear switches 23 are expediently arranged at locations where there is a risk of tearing along the path of the paper web 2.
  • the paper tear switches 23 enable the rapid stop process to be triggered automatically.
  • the hand switch 22 also enables the operator to intervene in the event of imminent danger.
  • the first additional brake 13, which is provided in the illustrated exemplary embodiment in addition to the additional brake which can be operated as a residual roller brake 15 and which can only be activated when a quick stop operation is carried out, does not require any regulation and therefore also does not require an upstream control element.
  • the electromagnets 14 provided here can therefore be controlled directly by the paper tear switches 23 or the hand switch 22 via an assigned input 24.
  • the additional brake 13, assigned to the roll to be braked and feeding the paper web 2, of the additional brakes 13 arranged on each arm of the roller star 5 is expediently activated by an automatic dial indicated at 25.
  • this automatic control 25 also leads to the output of the control element 16 assigned to the auxiliary brakes that can be operated as residual roller brakes 15, which ensures that, on the one hand, the presence of a quick stop pulse in the loading rich of the arm to be braked 3 receiving the arm of the roller star 5 installed, provided as a residual roller brake 15 brake is put into operation as a second additional brake, and that on the other hand when braking the residual roller 7 by means of the residual roller brake installed on the arm of the roller star 5 receiving the residual roller 7 15, the residual roller brake 15 arranged on the arm of the roller star 5 that receives the roll 3 that feeds the web 2 is also not put into operation.
  • the double braking of the material roll feeding the web which takes place on the circumference and in the area of the axis of the roll to be braked, enables the comparatively short braking time to be maintained when a quick stop operation is carried out.
  • the braking time could be reduced from 15 to 10 seconds compared to a simple braking, which was achieved exclusively via the belt drive, without any damage to the paper web being detectable.
