Definitions

  • the invention relates to a flat bed sheet punching and / or embossing machine according to the preamble of claim 1 and a method for quick shutdown of a flat bed sheet punching and / or embossing machine according to claim 7.
  • the cutting is referred to with closed geometric blank forms that can be circular, oval or polygonal and imaginary shapes of all kinds.
  • practices practiced in print finishing such as punching with punch, corner punching and register punching are counted to this area.
  • the punching takes place against a punching pad or against stamp, in some cases it is also shearing operations.
  • Plastic packaging materials, film material, paper, cardboard, cardboard or corrugated board are mainly punched in sheet format but also in web format. In the punching process, however, score lines or blind embossing can also be introduced into the benefit.
  • Such a flat bed punch is for example from the DE 30 44 083 A1 and the US 7,658,378 B2 known.
  • the two tables are equipped with cutting and scoring tools or corresponding counter tools, with which punched out of the cyclically guided between the table surface sheet benefits and at the same time pressed the necessary for clean folding grooves. In the subsequent breakout the waste is removed by machine tools. Depending on the equipment of the machine finally the punched benefits can be separated in a designatedWhentrenn arthritis.
  • the chain drive of the sheet transport system is disconnected from the drive in overload by means of an overload clutch, which is designed as a fixed point clutch.
  • the overload can arise, for example, as a result of collision of the gripper bridges with tools or due to paper jams.
  • the fixed point coupling is designed as a detent coupling, which can engage in an angular position.
  • a trigger sensor is integrated, so that this determine the release of the clutch and can forward to the drive.
  • the flywheel of the drive is subsequently separated by a controllable pneumatic cylinder from the drive train and at the same time the drive train braked by a brake, by a so-called clutch brake combination.
  • the disadvantage of this design is twofold: The release torque of the fixed point clutch must be set so high that during normal machine operation during a complete cycle, ie machine angle 0 to 360 °, the clutch does not trigger.
  • the danger that collide with the lowering punching tools or stripping or storage tools by triggering the overload clutch and the associated cancellation of the synchronization of transport chains and lifting movement of the processing stations, in particular the punching station, attached to the transport chains gripper bars and to be destroyed.
  • Object of the present invention is therefore to provide a flat-bed sheet punching and / or embossing machine, in which a better protection of the drive is guaranteed in the event of overloads occurring and the destruction of gripper bars and processing tools in the event of shutdown of the machine due to Overload is further reduced, as well as a method to describe how an emergency shutdown of a flat bed sheet punching and / or embossing machine can be implemented with these advantages.
  • a flat-bed sheet punching and / or embossing machine for processing sheets, in particular of paper, cardboard, plastic or cardboard with a sheet transport system, at least one processing station with hubbewegtem tool, at least one drive for driving the sheet transport system and the at least one Processing station and with a machine control.
  • a common drive for sheet transport system and processing stations is provided.
  • the sheet transport system preferably has two, alternatively also a plurality of circumferential substantially parallel chains with attached gripper carriage with grippers and a chain drive for driving the chains, wherein the chains with the chain drive in Engage.
  • the chain drive in turn is connected via a drive train to the drive.
  • the drive train is connected to the drive via a shiftable clutch-brake combination and via a shiftable clutch to the chain drive.
  • the sheet transport system has at least one sensor for monitoring the sheet transport system for errors and / or defects and the clutch-brake combination, the clutch and the at least one sensor are in communication with the machine control in a data exchange connection, for switching the clutch-brake combination and optionally the coupling depending on the measurement result of the sensor.
  • the at least one sensor of the sheet transport system permanently monitors the sheet transport system for a possible overload, transmits the measurement result, in particular via data lines to the machine control, where the measurement results are evaluated and if exceeding the setpoint values stored in the machine control, the clutch brake Combination and possibly also the clutch can be triggered.
  • a limit value can be stored as a permissible setpoint in the machine control, but rather setpoint curves can be stored, ie permissible values as a function of the machine angle. It is also possible that not only a setpoint is stored, but a tolerance band, which then simultaneously a maximum value monitoring, ie a collision prevention as well as a minimum value monitoring, ie a detection on chain crack of the transport chain includes.
  • the at least one sensor is arranged in the power flow of the chain drive, in particular in a chain wheel of the chain drive or in the region of an inlet curve or outlet curve of the chain wheel.
  • the sensor can also be integrated in a chain tensioner of the chain drive.
  • the sensor can also measure the wear-related chain elongation, ie the change in the distance between each two chain pins.
  • the sensor can also be located in at least one chain and / or in at least one gripper carriage. This allows the prevailing force to be measured and monitored directly on site.
  • the sensor can be designed as a force sensor, displacement sensor, temperature sensor or optical sensor. Alternatively, the sensor may also be designed as an acoustic sensor, which is arranged somewhat spaced from the sheet transport system in the machine and can detect deviations from the normal transport noise.
  • Force sensors and displacement sensors can be used in particular in the area of the chain tensioner.
  • temperature sensors By means of temperature sensors, the temperature of chain guides or chains can be detected and e.g. be reacted quickly in case of lack of lubrication.
  • Acoustic sensors can be used to detect sound patterns and their changes, e.g. in case of failure of the chain guide track.
  • Contact sensors can be used at the front edge of the gripper bridge to detect individual paper or accumulated paper. Also, a sensory evaluation of vibrations in the area of the sheet transport system can take place.
  • the setpoint values are dependent on the machine angle and / or on the machine speed and / or on the sheet weight of a sheet to be processed, since the forces which occur essentially depend on these factors.
  • the setpoints can either be calculated by the machine control or are stored in this.
  • the measurement results are subjected to a calculation before the comparison with the desired values.
  • a subtraction of the drive side and operator side measured forces can take place, it can be carried out a time derivative of the measurement results in order to better analyze changes.
  • the calculated setpoint values which are used for the comparison with the measured values, may be average values of past measurement results.
  • a machine angle-dependent average value of the measurement results can be formed from the past ten measurements. This allows deviations to be detected more quickly. Also, this can take into account the changing forces due to the heating of lubricant in the machine.

As long as the effective force F K in the transport chain 701 remains below this limit, the fixed point clutch 703 does not trigger. In addition, the breaking force F B of a gripper bar 8 is shown. From this representation, it can be seen that a breaking of a gripper bar 8 requires a considerably lower force than the disengaging force F A.
