Definitions

  • the invention relates to a method and a device for optimizing the idle time of the press beam of a cutting machine, in particular in a cutting machine for cutting stacked, leafy material made of paper, cardboard or the like.
  • a hydraulically actuated press beam is lowered onto the goods before the goods on a table of the cutting machine are cut and raised to a defined upper end position after the cut.
  • This upper end position is unchangeable, the distance of the press beam in its upper end position to the table surface is greater than the maximum insertion height of the material to be cut.
  • the disadvantage of such a cutting machine is the idle time of the press beam if material with a low insert height is to be cut.
  • a considerable idle time passes until the press beam is lowered from its upper end position to the material to be cut or is raised to its upper end position after being cut from the stack.
  • the large idle times have an overall adverse effect on the length of the cutting cycles of the cutting machine if it is to be operated automatically.
  • the feed for the material to be cut is only activated when the press bar has been raised completely.
  • the idle time of the press bar can be greater than the feed time for the material to be cut.
  • DE-AS 11 90 431 for a cutting machine for paper, cardboard or the like which has a hydraulic knife drive and a press beam
  • the material feed can begin.
  • a switching device on cutting machines for paper, cardboard or the like which has a cutter bar with attached to this knife and a machine-controlled, automatic drive of the press beam.
  • a device which triggers its drive and is influenced by the rising cutter bar at a certain height is arranged. This is formed on the one hand by a switch with a switching roller and on the other hand by an inclined surface which guides the switching roller and controls the switch.
  • the pressing pressure is released in the cutting machine when the cutting knife leaves the stack during lifting, and the lifting movement of the pressing bar begins at this point in time.
  • the lifting movement of the press beam is thus matched to the lifting movement of the cutting knife, but not the lifting height of the Press bar to the insertion height of the material to be cut.
  • the method for optimizing the idle time of the press beam of a cutting machine in which a hydraulically actuated press beam is lowered onto the table and cut after the cut before the stacked sheet-shaped material is placed on a table and is raised after the cut, is characterized in that when the press beam is lifted off cutting goods, a defined distance of the press beam from the goods is detected and the lifting movement of the press beam is ended when the defined distance is detected or is stopped after a delay after the detection of the defined distance.
  • the press bar is only raised as far as necessary after the cut, so that the insertion height of the material currently being cut is also lowered from this height to the material to be cut, provided the same insertion height is used, wherein the lifting movement of the press beam is either stopped immediately upon detection of the predetermined distance from the material to be cut and the press beam, or a timer is activated to stop the lifting movement of the press beam.
  • the interposition of a timer is particularly important from the point that the material to be cut can have different hardnesses.
  • the press bar carries out a relatively short lifting movement, while in the case of soft material to be cut, due to the fact that it relaxes after the press bar has been lifted, the press bar should carry out a relatively long lifting movement. If, on the other hand, the lifting movement of the press beam is terminated immediately upon detection of the defined distance, the hardness of the material to be cut cannot generally be taken into account during the lifting movement of the press beam.
  • the inventive method enables the feed for to activate the material to be cut when the defined distance of the press beam from the material has been detected.
  • the idle times of the cutting machine in automatic operation can be considerably reduced from this point of view, in addition there is a time saving because the press bar only has to be lowered from a lower height to the material to be cut that is being fed.
  • the lifting movement of the press beam is advantageously terminated at a distance of 10 to 20 mm between the press beam and the material to be cut.
  • the raised press beam is thus a minimum of 10 mm above the material to be cut, if the expansion of the material to be cut is not taken into account after lifting the press beam. If a timing element is provided, the defined distance would have to be chosen shorter so that the lifting movement of the press beam is completed at a distance of 10 to 20 mm from the material to be cut.
  • the defined distance of the lower edge of the press beam to the upper edge of the stack of material to be cut is detected by means of a detection element which is arranged in a stationary manner on the press beam in its lifting direction. Due to the stationary arrangement of the detection element on the press beam, the latter moves the same path length and therefore feels the position of the upper edge of the cutting stack, that is to say specifically the transition from the stack of material to be cut, to the air due to the arrangement following the pressing beam. As soon as the detection element detects the upper edge of the material to be cut, the lifting movement of the press beam is terminated or the timer is activated to stop the lifting movement of the press beam. The latter leads to a defined overrun of the press beam.
  • the lifting movement of the press beam is ended or the timer is activated to stop the lifting movement of the press beam.
  • a preferably designed device for cutting stacked, sheet-shaped material has a table for receiving the material to be cut, a feed unit for the material to be cut, a hydraulically actuated press bar that can be lowered onto the material to be cut, and a press bar that is arranged adjacent to the press bar.
  • Cutting knife movable perpendicular to the table plane, and a sensor interacting with a circuit for the hydraulic system of the press beam, the device being characterized in that the sensor is arranged below the press beam and outside of it, on the press beam, with the active surface coming into contact with the material to be cut, whereby the effective distance of the sensor from the press beam effective surface corresponds to the defined distance at which the sensor generates a signal which leads to the immediate or time-delayed termination of the lifting movement of the press beam.
  • the sensor detects the top edge of the material to be cut, its effective line or effective plane runs parallel to the press beam effective surface.
  • the effective distance of the sensor from the press beam effective surface corresponds to the defined distance from the lower edge of the press beam and the upper edge of the material to be cut, at which the lifting movement of the press beam is ended or the timer is activated to stop the lifting movement of the press beam.
  • the sensor in which the sensor can be moved together with the press beam, the sensor should basically have a first element, which in the region of one end face of the Press beam is arranged, and a second element which is arranged in the region of the other end face of the press beam. The sensor thus detects the stack to be cut between its two elements.
  • the sensor itself can be designed in different ways, for example as a light barrier, which has a light source and a photo cell as elements.
  • the sensor is expediently not only arranged outside the press beam, but also outside the table surface.
  • the pressure beam can thus be lowered onto the table surface without causing damage to the sensor in a table designed in the usual way.
  • a further, preferably designed device for cutting stacked, sheet-like material provides that instead of the sensor arranged on the press beam, several sensors are arranged at different distances from the table level in the machine frame guiding the press beam, each sensor being effective parallel to the table plane to determine the current height levels of the upper edge of the material to be cut and the lower edge of the press beam relative to the table surface by means of the sensors, the immediate or time-delayed reduction of the press pressure of the press beam taking place at a defined distance level of inactive sensors.
  • the sensors assigned to it are activated in accordance with the insertion height of the material to be cut and the sensors assigned to it are activated in accordance with the position of the press beam.
  • the number of non-activated sensors arranged one above the other represents the distance from the lower edge of the press beam to the upper edge of the stack of material to be cut, the resulting measurement accuracy or measurement inaccuracy being due to the distance between adjacent sensors is taken into account.
  • the sensors are expediently designed as light barriers which, as described above, detect the material to be cut between the two elements of each light barrier.
  • Figures 1 and 2 show, in a highly simplified manner, the upper area of a face cutting machine for cutting paper, cardboard or the like.
  • the face cutting machine has a base frame, not shown, which receives a table 3 and the machine frame 9 which extends above the table and is designed as a portal frame.
  • the table 3 has a cutting bar 4 embedded in it and extending over the entire width of the table 3.
  • a feed unit 2 with a feed saddle 2a extends across the width of the table 3. This can be moved in the direction of arrow C, which results in the basic direction of movement of the material to be cut during the cutting process.
  • a cutting knife 7 is arranged above the cutting bar 4. Shown in Figures 1 and 2 is the raised position of the cutting knife 7, from which it can be lowered in the direction of arrow D to the cutting bar 4. Adjacent to the cutting knife 7 there is a press beam 8 on the side facing the feed unit 2, which can also be lowered from the raised position shown in FIGS. 1 and 2 in the direction of arrow D onto the material 1 to be cut.
  • Cutting knife 7 and press beam 8 are guided in the portal frame 9 of the face cutting machine which surrounds them at the top and on the sides.
  • the cutting knife 7 is connected to the cutter bar 11 by means of screws 6.
  • the knife 7, the cutting edge 7a of which is slightly inclined from the horizontal, can be moved in a pulling cut in a known manner by means of a crank mechanism (not shown).
  • the press beam 8 is guided in the region of its two end faces in the vertical legs 9a of the portal frame and can be moved in the direction of arrow D by means of a hydraulic drive.
  • Reference number 10 shows the cutting plane of the cutting knife 7, which extends perpendicular to the table surface 3a and through the cutting bar 4.
  • the control panel of the face cutting machine is designated by reference number 12.
  • the known face-cutting machine described so far has a sensor in the form of a light barrier below its active surface 8a which comes into contact with the material 1 to be cut, which comprises a light source 13 and a photocell as elements 14 has.
  • the light source 13 and the Photocell 14 are arranged in the area of the two opposite end faces of the press beam 8, thus outside the active surface 8a which comes into contact with the material 1 to be cut, and also outside the table surface 3a.
  • the contours of the light source 13, photocell 14 and press beam 8 located in the region of the two legs 9a of the portal frame 9 are illustrated with dashed lines.
  • Reference number 15 denotes the beam of the light barrier, which runs at a defined distance Z and parallel to the active surface 8a of the press beam 8.
  • the light barrier is connected via an electrical circuit to the hydraulic system for the pressure beam 8, specifically after the pressing beam 8 has been placed on the material to be cut, the light barrier is activated due to the interruption of the light beam 15 by the material 1 to be cut.
  • the light barrier is deactivated and the electrical circuit is controlled by it so that the lifting movement of the press beam 8 is ended immediately or is terminated with a time delay after detection of the defined distance by means of a timer integrated in the circuit.
  • the signal for immediate or delayed termination of the lifting movement of the press beam 8 is only generated when the distance of the Active surface 8a of the press beam 8, which is equivalent to its lower edge 8b, to the surface 1a of the material 1 to be cut, which is equivalent to its upper edge 1b, which corresponds to the effective distance Z.
  • the distance between the light barrier 15 and the lower edge of the press beam 8b corresponds to 10 mm in the exemplary embodiment. If the light barrier is designed in such a way that the activation of the signal immediately leads to the lifting movement of the press beam 8 being terminated, the reduction takes place at a distance of the press beam 8 from the material 1 to be cut 1 of 10 mm. If a timing element is additionally provided, the lifting movement of the press beam 8 is only ended at a greater distance from the material to be cut. Basically, the effective distance Z or the time delay should be chosen according to the practical circumstances, it is crucial that, according to the design according to the invention, it is no longer necessary to move the press beam 8 back into its uppermost possible end position.
  • FIG. 5 shows a further embodiment in which, instead of the horizontally effective light barrier attached to the underside of the press beam 8, a multiplicity of horizontally active light barriers are arranged in the region of the two inner surfaces 17 and 18 of the portal frame 9 (see FIG. 2).
  • the material 1 to be cut is not shown there for a better understanding of the design of the cutting machine, the reference number 19 illustrates a side stop attached to the table 3.
  • 5 shows only the large number of photocells 14 arranged one above the other at a defined distance from one another, and accordingly the inner surface 17 of the portal frame 9 is provided with a large number of light sources arranged at a distance from one another and one above the other.
  • one or more of the lower light barriers is activated in accordance with the insertion height, that is to say the stack height.
  • the press beam 8 is raised in the direction of arrow E, the light barriers located between the active surface 8a of the press beam 8 and the surface 1a of the material 1 to be cut are deactivated by the latter according to its lifting distance.
  • the number of non-activated light barriers is a measure of the distance of the press beam 8 from the material to be cut 1.
  • the electrical circuit which interacts with the hydraulic system for the press beam 8 is designed in this embodiment in such a way that at a defined distance level, that is to say with a bandwidth of inactive light barriers, expressed by the effective distance Z as a defined distance, the lifting movement of the press beam 8 is ended immediately or with a time delay.
  • Parts corresponding to the embodiment according to FIGS. 1 to 4 are designated by the same reference numerals in FIG. 5, the remarks relating to this embodiment regarding the optimization of the idle time of the press beam also apply.
  • the feed unit 2 is preferably activated.
  • the cutting knife 7 is returned to its raised rest position in advance of the press beam 8, and after the entire stack 1 has been separated, the multiplicity of benefits, the feed unit 2 is moved back to its starting position counter to the arrow direction C.
