Definitions

  • the invention relates to a device for connecting a material web close to its web end with the web start of a second web and includes the features contained in the preamble of claim 1.
  • Such a device is known for example from DE 34 11 398 A1. It is used to connect the beginning of the web of a material web wound up to a replacement winding roll with the web end of a material web unwound from an outgoing winding roll and has an upper and a lower carriage in which deflection rollers for the material webs and pressure rods with holding and pressure heads are stored.
  • the holding and pressing heads work with suction air to fix the respective web start and are not only movable towards each other, but also after moving the carriage in the pressing direction freely pivotable such that the beginning of the web fixed to them can be covered with adhesive or an adhesive strip in an easily accessible manner by a machine operator.
  • the cutting knife is namely arranged in a knife carriage into which the web end must be guided before being cut. During the severing process, the end of the web is at an angle to the severing knife or its knife stroke. Brushes are provided as a counter tool for the cutting knife, which should ensure a clean cutting cut in view of the acute cutting angle.
  • the arrangement of the holding and pressing heads on slides, their additional, mutually directed pivotable mounting on the slides and the special arrangement and location of the cutting knife with its drive in a plane between the two slides requires a great deal of constructive effort overall, which is also due to its special features is prone to failure with additional angle and control levers.
  • the invention is therefore based on the object of providing an easy-to-use and easy-to-use device for connecting webs of material, and furthermore the design effort is low.
  • the invention provides that the holding and pressing heads can be pivoted about axes, which are arranged at a distance from the deflection rollers and outside the space between the deflection rollers.
  • the position and arrangement of the axes for the pivotable mounting of the holding and pressing heads makes it possible to dispense with slides for mounting the deflecting rollers and the holding and pressing heads which carry out a lifting movement and a pivoting movement.
  • the mechanical expenditure is therefore lower, with the result that there is also a lower susceptibility to malfunctions despite constant ease of use.
  • a device 1 for connecting a material web 2 near its web end to the web start 3 of a second material web 4 comprises two holding and pressing heads 5, 6, between which the material web 2 is guided from a roll 7 on a roll stand 8 to a storage station 9.
  • the holding and pressing heads 5, 6 are both movable towards one another, ie beyond a central plane 2a located between them, and are also pivotably mounted in a machine frame (not shown in the figures).
  • a piston-cylinder device 10 is provided in each case to achieve the lifting movement of the holding and pressing heads 5, 6 directed towards and away from each other.
  • the holding and pressing heads 5, 6 are furthermore preferably arranged together with their respective piston-cylinder device 10 on a carrier 11 and are mounted together with the latter in the machine frame so as to be pivotable about an axis 12 in each case.
  • the piston-cylinder device 10 with the pressure head 5 is shown in Fig. 9 in principle and on a larger scale and comprises two cylinders 10 'and 10' 'with piston rods 10a and 10b.
  • the two cylinders 10 'and 10' 'and their piston rods 10a and 10b are commercially available parts.
  • the two cylinders 10 'and 10' ' are also rigidly connected to one another, as the figures show.
  • the piston rod 10a of the cylinder 10 ' carries the holding and pressing head 5 at its free end 10c, while the other piston rod 10b is fastened to the carrier 11 with its free end 10d. Both the attachment of the holding and pressure head 5 to the piston rod 10a and the attachment of the piston rod 10b to the carrier 11 are expediently carried out with the aid of screws 10e.
  • the pressure head 5 is guided in a parallel guide, not shown in the figures, which is rigidly connected to the carrier 11 and extends parallel to the piston rods 10a and 10b.
  • the holding and pressing head 5 can thus be displaced exactly by separately actuating the two cylinders 10 'and 10' 'of the piston-cylinder device 10.
  • Deflection rollers 13 and 14 for the material web 2 and for the also from a roller 7a on a second unwind stand 8 located material web 4 are in the running direction 100 of the material webs 2, 4 directly in front of the two holding and pressing heads 5, 6.
  • the two stationary guide rollers 13 and 14 are at a short distance from each other. Between them there is a cutting knife 15 inside a cutting head 16 for cutting off the respective web end.
  • a push rod 17 is provided as the drive for the cutting knife 15 and is shown in principle in the figures without its drive.
  • a braking device 19 controlled by high-speed cylinders 18 is also assigned to both the material web 2 and the material web 4.
  • Suction air is used to fix the respective web start 3 to one or the other holding and pressing head 5, 6.
  • the two holding and pressing heads 5, 6 are therefore provided with suction air openings 20 (see FIG. 9), at which a vacuum is generated in a precisely defined form with the aid of a vacuum generator not shown in the figures and with the help of control valves not shown.
  • the holding and pressing head 6 is first folded up into a preparation position according to FIG. 2 and the new material web 4 is pulled off the roll 7a and between the deflection roller 14 and pulled through the cutting head 16 or threaded. Then the beginning of the web 3 is aligned precisely on the holding and pressing head 6 with the aid of a measuring scale 6 'and fixed with the aid of suction air, for which purpose there are suction air openings 20 in the holding and pressing head 6 as well as in the holding and pressing head 5.
  • the material web 4 can also be pulled somewhat beyond the holding and pressing head 6, since protruding web material is cut off again, for which purpose an auxiliary groove 60 in the holding and pressing head 6 and an auxiliary groove 60 in the holding and pressing head 5 are arranged (FIG. 2 or Fig. 9).
  • double-sided adhesive tape 23 is also applied in the exacting position in the pressing area of the holding and pressing head 6 on the beginning of the web 3. Then the holding and pressing head 6 is pivoted back into its starting position (FIG. 3) and the material web 4 is tensioned by turning back the roller 7a.
  • the holding and pressure head 6 is now moved into its pressure position. This is done with the help of the cylinder 10 'and the associated piston rod 10a, which only has to move the holding and pressing head 6 a little from the retracted initial position to a possible pressing position.
  • the distance traveled here can be of the order of magnitude of approximately 5 mm, the position shown in FIG. 3 then also being reached.
  • the material web 2 is stopped by the associated braking device 19 and the processing machine (not shown in FIG. 1) receives the required material from the storage station 9.
  • the material web 4 lies on or over the free end of the cutting head 16 and runs from the deflection roller 13 on the left on the cutting head 16 initially in an arc shape to the free end of the cutting head 16 and then in an opposite arc on the holding and pressing head 5 and from there to the first deflection roller 9 'of the storage station 9.
  • the material web 2 is cut with the aid of the separating knife 15 and a cutting gap 25 located in the holding and pressing head 5, the separating knife 15 being immersed in the cutting gap 25 (FIG. 5).
  • the negative pressure in the holding and pressing head 6 is released, so that the material webs can detach from the holding and pressing head 6.
  • the holding and pressing head 6 is only moved back a little by means of the cylinder 10 'of its piston-cylinder device 10. This has the consequence that the adhesive tape 23 or the beginning of the web 3 of the material web 4 is released not only by the holding and pressing head 6, but also by the other holding and pressing head 5 takes off, as shown in Fig. 6.
  • the three deflection rollers 9 ', 13 and 14 form an acute-angled triangle in the running direction of the material webs 2 and 4, which is halved by the central plane 2a.
  • the holding and pressing heads 5 and 6 move to connect the material webs 2 and 4 with their circumference in each case beyond the middle plane 2a, as is also shown in FIGS.
  • the two axes 12 used for pivoting the holding and pressing heads 5, 6 are arranged at a distance from the deflecting rollers 13, 14, specifically from the cutting head 16, each outside outside the deflecting rollers 13, 14. In the space 27 between the deflecting rollers 13 and 14 there is only the cutting head 16 with the cutting knife 15.
  • the axes 12 are distant from the deflection rollers 13, 14 and, according to the exemplary embodiment, are only slightly offset from a straight line connecting the deflection rollers 13, 14.
  • FIG. 8 shows a slightly modified embodiment with holding and pressing heads 105 and 106, respectively. They are essentially circular in cross section. Furthermore, in this embodiment, the cutting gap is not provided directly in the holding or pressing head 105, 106, but is arranged in a cutting plate 24. Function and mode of operation is otherwise the same as in the first embodiment described.
  • one-sided coated adhesive tapes can also be used in the device 1, in which case the two material webs 2, 4 are butt-glued to one another.
  • the various steps described above change only slightly when using a single-sided adhesive strip. He too must be exactly on the Holding and pressure head 5, 6 are fixed by means of vacuum, whereupon the beginning of the web 3 of the new material web 2, 4 is pressed onto the adhesive surface of this adhesive tape 23 such that half of the adhesive surface remains free for gluing the web end of the other material web.
  • the two holding and pressing heads 5, 6 and their piston-cylinder device 10 are substantially perpendicular to the central plane 2a and can be folded away from the cutting knife 15 about the axes 12 in the running direction of the material webs 2, 4. This puts you in a position in which they are easily accessible and threading a new material web is easy.
  • the short stroke of, for example, 5 mm is sufficient if the geometric position of the two deflection rollers 13 and 14 relative to one another and relative to the deflection roller 9 'in the storage station 9 is selected as in the exemplary embodiment shown and Material web directions from the deflection roller 13 to the deflection roller 9 'on the one hand and from the deflection roller 14 to the deflection roller 9' on the other hand enclose an acute angle. Very little time is then required to release the glued material web, but on the other hand there is sufficient time to pull the separating knife 15 out of the cutting gap 25 again and to move the associated holding and pressing head back into its starting position. The function and mode of operation of the device for connecting material webs is therefore safe and reliable.
