Definitions

  • the invention relates to a method for controlling and/or monitoring a web-processing machine according to the preamble of claim 1 .
  • control signals must activate not only the signals but also other work steps of machines. Such control signals can also originate from a control unit programmed for this purpose.
  • the object of the present invention is to provide a more reliable method. This object is achieved by the characterizing part of claim 1 .
  • the angular speed of the roll can be measured in that suitable rotary encoders monitor the rotation movement of the roll and plot it against the time.
  • the web speed can be recorded in a comparable manner with the help of rotary encoders, for example, on transport rollers, printing rollers or impression rollers.
  • the diameter of these rollers usually remains constant while the roll is unwound as a result of which its diameter shrinks.
  • the web length which is measured by the web speed sensor during the rotation of a roll, corresponds to the circumference of the roll in this period of time.
  • the circumference increases from rotation to rotation by an amount, which substantially corresponds to the thickness of the web material.
  • the absolute disturbance variables which result due to the start of the web and which are substantially constant in the case of the difference between the successive layers, inter alia play a role in this connection. Particularly these disturbance variables can be determined or even eliminated completely if the web thickness is determined in the manner described over a plurality of rotations.
  • a control device implements the method in an automated form. For example, if the circumference of the winding sleeve—in case the roll comprises one such winding sleeve—is known to this control device, it can take this variable also into consideration when determining the point in time. If there is no winding sleeve present, a minimum circumference or diameter of the roll can be used in its place.
  • a guide roller whose rotary movement is monitored by a rotary encoder (incremental encoder), is used for determining the web speed or web length. This can take place in a similar manner in the case of printing machines.
  • the single FIGURE illustrates a schematic lateral view of an inventive device for implementing the inventive method.
  • the FIGURE illustrates schematically a web-processing machine 1 .
  • a web-processing machine 1 can basically be a continuously operating machine, such as for example, a printing machine or a laminator or a machine operating at a given cycle rate, for example, an FFS machine, mentioned at the outset. Webs are supplied continuously to both the continuously operating machines as well as the machines operating at a given cycle rate.
  • the web-processing machine 1 is equipped with a draw unit 2 .
  • This draw unit consists of a first roller 3 and a second roller 4 , at least one of which is driven continuously. Both the rollers 3 , 4 form a roller clearance through which the web 5 is conveyed in the web running direction z.
  • the machine 1 is illustrated in the FIGURE as a machine operating at a given cycle rate.
  • the machine is equipped with a web storage unit 6 , known per se, in which rolls 7 are mounted in a swivel arm 8 , which is attached in a machine frame (not illustrated in detail), while the roll 9 is rotatably connected to the machine frame and is therefore stationary, however rotatable.
  • At least one of the subsequent rolls 10 is driven intermittently and thus ensures the feed of the web 5 at a given cycle rate.
  • the web 5 is usually supplied to the web-processing machine 1 in the form of a web roll 12 .
  • the latter is non-rotatably connected to an axle 13 , which penetrates through the winding sleeve 14 of the web roll 12 and which is mounted rotatably in the unwinding device 11 .
  • the unwinding device 11 can comprise at least one additional web roll (not illustrated in detail).
  • the unwinding device 11 further comprises a joining station 15 .
  • This joining station 15 comprises a cross-cutting blade 16 using which the unnecessary web remainder can be cut off from the web end when or shortly before the web 5 is unwound completely from the web roll.
  • the joining station 15 comprises additionally holding means 17 , using which the start of a web which is wound up on another web roll, is held in a waiting position. If a tube is used as a web, this tube can be provided with slots in the region of its lateral edges, so that two walls separated from one another are formed at the web start 18 . These walls can be folded over in vertical positions as illustrated in the FIGURE.
  • a control device receives or determines the point in time at which the web end on the web roll 12 is reached.
  • control device delivers control signals using signal lines (also not illustrated) to the joining station 15 and to the machine 1 , if necessary. Activated by these signals, the web 5 is first drawn forward further in the web transport direction until a predetermined position is reached. Subsequently, the cross-cutting blade 16 , if necessary, cuts off the web remainder from the end of the web 5 , which is held on by clamping means 19 . The holding means 17 now transport the web start 18 into a position, in which the longitudinal axis of the web 5 and that of the new web align with one another. Subsequently, the web start 18 is joined to the end of the web 5 , for example by gluing or welding.
  • signal lines also not illustrated
  • the unwinding device comprises a signal transmitter 20 , which delivers a signal to the control device when the marking attached to the axle 13 passes the signal transmitter.
  • the control unit can determine the angular speed ⁇ of the web roll 12 from the number of signals and the associated elapsed time.
  • the signal transmitter can scan the marking in different ways, for example, optically, magnetically, electrically or mechanically. Other types of speed measurements are also applicable on such an unwinding device.
  • the control device obtains information about the web speed v.
  • one of the rollers or rolls, which transport the web 5 continuously is equipped with a rotary encoder.
  • the roller 5 [sic] of the draw unit is equipped with the rotary encoder.
  • the control unit can determine the instantaneous speed v of the web from the angle about which the roller or the roll moves per time unit and the circumference of the roller or the roll.
  • other methods for determining the web speed are applicable.
  • the control unit can now determine the development of the circumference of the web roll 12 as a function of the time by comparing the speed v of the web with the angular speed ⁇ of the web roll 12 . Simple geometric relations are used as the basis for calculation. If the parameters of the winding sleeve 14 , which allow inferences to be drawn about its outer diameter, are additionally known to the control unit, then the control unit can determine, precisely and in advance, the point in time T at which the end of the web 5 on the web roll 12 can be expected to be reached. The control unit can naturally calculate the length of the web 5 in advance, which can be still processed to the maximum extent. In this manner the web remainder is reduced while still enabling the joining process in the connection station 15 .
