Definitions

  • the present invention relates to a method for controlling a role change process in a web unwinder of a processing machine according to the preamble of patent claim 1.
  • the invention is not limited thereto, but rather applicable to all types of web-processing machines in which a roll change takes place.
  • the invention is particularly useful in printing machines, such as e.g. Newspaper printing machines, commercial printing machines, gravure printing machines, packaging printing machines or securities printing machines, as well as processing machines, e.g. Pouch machines, envelope machines or packaging machines, can be used.
  • the web can be made of paper, cloth, cardboard, plastic, metal, rubber, in foil form, etc.
  • the unwinding device includes a reelstand to replace a rolling first reel during operation with a fresh second reel.
  • the change takes place either "flying", ie first and second rollers rotate and are connected, usually by means of an adhesive strip provided on the second roller glued, or at a standstill, ie first and second role while they are connected.
  • first and second rollers rotate and are connected, usually by means of an adhesive strip provided on the second roller glued, or at a standstill, ie first and second role while they are connected.
  • a web store which is emptied during the connection process.
  • An unwinding device for a flying reel change is, for example, in the DE 26 19 236 A1 described.
  • the role change is controlled depending on the diameter of the declining roll. However, it has been shown that this type of control does not always lead to an optimal result.
  • the invention is based on the recognition that the position of the connection, in particular splice, on the web can be specified and automatically targeted so as not to adversely affect subsequent processing operations.
  • the junction of the two webs is both thicker than a single web and usually contaminated with an adhesive.
  • certain processing equipment may be disturbed, for example, a cutting blade may be contaminated with adhesive, printing or drying operations are not performed properly, etc.
  • it can be achieved that the joint of the webs reaches the at least one processing means at a desired time.
  • the desired time can be set so that the junction of the webs is not affected by the at least one processing operation or that the junction of the Webs that at least one processing device at least not reached at an undesirable time.
  • the location of the joint is not considered relative to a processing device, i. the location is arbitrary.
  • the connection point can pass through the processing device at any point in time, which could possibly happen. is detrimental to the machining process.
  • the adhesive strip sticks a cutting knife due to adhesive deposits.
  • It can also come through a thicker web in the area of the adhesive tape to transport problems, if, for example, a processing device in a region of its circumference has a larger diameter and thus a stronger clamping of the web occurs.
  • the invention provides a method by which the joint is automatically set so that it does not affect subsequent processing operations or as little as possible. This is preferably achieved by a change in the web length between the unwinder, here usually an adhesive roller, and the critical processing device and / or by changing the connection time.
  • the adhesive roll determines the glue location, i. the location within the unwinder to which the webs are glued.
  • the combination of changing the web length and changing the connection time is particularly advantageous if the roll circumference of the new, second roll is variable.
  • the circumference of the new roll is a multiple of the print format, it may happen that after one or more revolutions of the new roll continues to get a problem adhesive position (shift is not big enough, since, for example, the scopes of new role and machining axis hardly differ) , In this case can be created by an additional change in the web length remedy.
  • the web length is preferably changed by a web extension device, in particular by changing a dancer position (eg dancer target position) and / or the degree of filling of a goods store.
  • the dancer and / or the web store can one or more dancers, wrappers (eg S-wrap) and the like. include.
  • an existing adhesive roll be moved, thereby causing a change in the touchdown point of the adhesive roller and thus the position of the joint.
  • the timing of the connection may be adjusted in dependence on the at least one processing operation, the timing of the connection being expediently adjusted by delaying the connection by one or more revolutions of the second roller.
  • the length between the unwinder and the first (formate-containing) processing device is appropriately considered, even if it is not the critical processing device, since this section is easy to view and often existing because of facilities such as e.g. Dancer, too, is easy to set. Furthermore, changes in this length of web and the web length between unwinder and adhesive roller and the critical processing device changes. In general, however, the web length between unwinder and adhesive roll and any formate-containing processing station can be considered and adjusted. The determination of the web length does not necessarily have to be determined between the adhesive roll and a critical processing axis.
  • the web length between the adhesive roller and the other processing device may also be used as a criterion.
  • the length determination between adhesive roller and a far-lying seam is more complicated than the length determination between the adhesive roller and the first printing unit.
  • the fold always has a fixed angular relationship to the printing unit (he must cut the pressure on the web at a fixed position), the easier to determine web length can be used to the printing unit.
  • the position of the connection point can also be changed during a roll change at standstill, that the speed of the old role is changed so temporarily, that thereby the position of the dancer roller is changed within the web memory.
  • the degree of filling of the web memory and thus the effective length of the web between adhesive roll and critical processing device at the time of reaching the standstill of the old role are changed.
  • the angular position of the critical processing device can be determined whether a critical processing operation would result.
  • An arithmetic unit according to the invention e.g. a control unit of a printing press, is, in particular programmatically, adapted to perform a method according to the invention.
  • Suitable data carriers for providing the computer program are, in particular, floppy disks, hard disks, flash memories, EEPROMs, CD-ROMs, DVDs and the like. It is also possible to download a program via computer networks (Internet, intranet, etc.).
  • FIGS. 1 and 2 are the same elements provided with the same reference numerals and will be explained only once.
  • FIG. 1 is a section of a processing machine for a web 113 roughly schematically shown and designated 100 in total.
  • the processing machine 100 comprises inter alia a reel changer 110, which carries two rotatable, drivable rollers 111 and 112 on a swivel arm (not shown). From the first roller 111, the first web 113 is unwound and fed to the processing.
  • the second roller 112 second roller carries a wound second web as a replacement and is fed to processing, in good time before the first roller 111 is empty.
  • the second roller 112 is provided with an adhesive strip 114 and brought to the peripheral speed of the first roller 111.
  • an adhesive roller 115 is employed to press the web 113 onto the roller 112.
  • the adhesive strip then connects on the subsequent reaching of the adhesive roller position, the first with the second web, so that the second web is fed together with the first web of processing.
  • the first web is separated by means of a likewise provided cutting blade 116, so that the first roller 111 can be replaced.
  • the processing device further comprises in its catchment area a usually provided dancer 117 as well as in the embodiment of the invention a web extension device 118, which is designed here as an S loop. It should be noted that the dancer 117 also represents a web elongation device.
  • a printing unit 120 and a folding device 130 are provided as processing devices.
  • All units of the winder 110 and / or the processing machine 100 are expediently controlled by a controller 150 designed according to the invention for this purpose.
  • the web length between the touchdown point of the adhesive roller 115 and the folding position (angular position) of the folding device 130 is the web length between the touchdown point of the adhesive roller 115 and the folding position (angular position) of the folding device 130.
  • the format length is the length between two folding knife interventions.
  • a longitudinal extension of the splice is expediently taken into account with this length.
  • the web length can be changed in a preferred embodiment by changing the Tänzerlageregler setpoint, by adjusting the S-wrap 118 and / or by shifting the glue location by moving the adhesive roller 115.
  • This variant of the web length change is particularly useful applicable when a standstill bond is used, since then the web length between the glue point and the processing device concerned can be determined easily.
  • the time of stopping can also be changed (eg by a lower one) Delay of the old role).
  • After stopping if necessary. Again, a short movement of the old role are performed, which then also changes the effective web length between adhesive roller and (angular) position of the critical machining axis.
  • the effective web length L eff is a multiple of the print format (taking into account the splice width) and thus the gluing would happen at an inappropriate moment the machining axis, for example, at the next or a later revolution of the new role, ie at a later possible gluing time the bonding can be done.
  • f 2korr is between 0 and 2p (360 degrees).
  • the difference between f 2 and f 2korr corresponds to the displacement of the splice at the processing device further revolutions of the new roll 112th
