Definitions

  • the invention relates to a method for controlling and / or monitoring a web-processing machine according to the preamble of claim 1.
  • Methods of this type are used, inter alia, in printing machines or bag making machines. Often, the operator is alerted to the approaching end of the material web by issuing warning signals. However, semi-automatic or fully automatic web-changing processes are also known. In these methods, not only the signals, but also other work steps of machines must be triggered by control signals. Such control signals can also originate from a control unit programmed for this purpose.
  • US 6,286,780 discloses an apparatus and method for tension control of a web in which the length of the unwound web is determined by a sensor and a tachometer.
  • the object of the present invention is to provide a more reliable method.
  • the object is solved by the characterizing part of claim 1.
  • the angular velocity of the roll can be measured by suitable encoders monitoring the rotation of the roll and applying it against time.
  • the recording of the web speed can be done in a comparable manner with the aid of encoders, for example, on transport, printing or counter-pressure rollers.
  • the diameter of these rolls usually remains constant while the roll is unwound so that its diameter shrinks.
  • the time or time measurement required to determine these two speeds means that a period of time is considered. In a continuous rolling movement that appears uncritical. But even with discontinuous rolling movements can be done in the speed determination averaging over a period of time. It is important that from the "web speed" the length of the web can be determined, which is unwound from the roll per unit time and then usually fed to the machining part of the machine.
  • absolute disturbances play a role, which arise due to the web start and which are essentially the same at the difference between successive layers.
  • these disturbances can be averaged out or even completely eliminated if the web thickness is determined in the manner described over a plurality of revolutions.
  • a control device carries out the method in an automated form.
  • the circumference of the winding tube if the role includes such, known, it may also take this size into account in the determination of the time. If no winding tube is present, a minimum circumference or diameter of the coil can be used at this point.
  • Very advantageous is the use of the method according to the invention in FFS machines, as described in the DE 199 20 478 A1 are shown. In these methods, there is usually a tubular web.
  • the use of a method according to the invention in a machine according to the DE 199 20 478 A1 for controlling and / or monitoring the material roll on such a machine is hereby incorporated in the disclosure of the present document.
  • FIGURE shows a schematic side view of a device according to the invention for carrying out the method according to the invention.
  • the figure shows a schematic representation of a web-processing machine 1.
  • a web-processing machine 1 can basically be a continuously operating machine, such as a printing or laminating machine or a clock-bound machine, such as an FFS machine mentioned above. Both the continuous and the clock-bound machines working trains are supplied continuously.
  • the web-processing machine 1 is equipped with a preference 2.
  • This advantage consists of a first roller 3 and a second roller 4, of which at least one is driven continuously. Both rollers 3, 4 form a nip through which the web 5 is conveyed in the web running direction z.
  • the machine 1 is shown in the figure as a clock-working machine.
  • the machine is equipped with a known rail memory 6, are stored in the rollers 7 mounted in a machine frame not shown swing arm 8, while the roller 9 is rotatably connected to the machine frame and therefore stationary, but rotatable.
  • At least one of the following rollers 10 is driven intermittently and thus provides for the cyclical advantage of the web. 5
  • the web 5 is provided to a web-processing machine 1, usually in the form of a web roll 12 available.
  • a web-processing machine for unwinding of the web 5 of the web winding 12 this is rotatably connected in a winding device 11 with an axis 13 which passes through the winding tube 14 of the web winding 12 and which is rotatably mounted in the winding device.
  • the unwinding 11 may have at least one further web winding, not shown.
  • the Anwickelvoriques 11 further comprises a connection station 15.
  • This connection station 15 comprises a cross-cutting blade 16, with which an unnecessary track remnant of the tail can be separated when or just before the web 5 has been completely unwound from the web roll.
  • the connecting station 15 also includes holding means 17 with which the web start of a wound onto another web-wound web is held in a waiting position. If a hose is used as a web, then this hose can be provided in the region of its side edges with cuts, so that at the web beginning 18 two separate walls arise. These walls can, as shown in the figure, be folded into vertical positions. In order not to have to thread the web start 18 of the new web in the web-processing machine 1 when the web roll 12 is completely unwound, the web start 18 is connected to the end of the web 5 within the connection station 15. For this purpose, a control device, not shown, obtains or determines the point in time at which the web end is reached on the web winding 12.
  • control device via control lines, also not shown, control signals to the connection station 15 and optionally to the machine 1 from. Initiated by these signals, first web 5 is further advanced in the web transport direction until a predetermined position is reached. Subsequently, if necessary by the cross-cutting blade 16, a web residue from the end of the web 5, which is held by clamping means 19, separated. The holding means 17 now transport the web start 18 to a position in which the longitudinal axes of the web 5 and the new web are in alignment. Subsequently, the web start 18 is connected to the end of the web 5, for example by gluing or welding.
  • the unwinding device comprises a signal generator 20, which emits a signal to the control device when the attached to the axis 13 mark passes the signal generator. From the number of signals and the associated elapsed time, the control unit can determine the angular velocity ⁇ of the web winding 12.
  • the signal generator can scan the marking in various ways, for example optically, magnetically, electrically or mechanically. Of course, other types of speed measurement can be used on such an unwinding device.
  • the control device obtains information about the web speed v.
  • one of the rollers or rollers, which continuously transport the web 5 is equipped with a rotary encoder.
  • the roller 5 of the preference is equipped with the rotary encoder. From the angle through which the roller or roller moves per unit of time and the circumference of the roller or roller, the control unit can determine the instantaneous speed v of the web. Again, other methods for determining the web speed can be used.
  • control unit can now calculate the evolution of the circumference of the web roll 12 as a function of time. The calculation is based on simple geometric relationships. If the control device also known parameters of the winding tube 14, the conclusions on the outer diameter, it can predict the time T, at which the end of the web 5 is expected on the web roll 12, precise precisely. Of course, the control device can calculate the length of the web 5 ahead, which can still be processed to the maximum. In this way, the web rest is minimized, but still allows a connection in the connection station 15.
