Definitions

  • the invention relates to a device for connecting the end of a material web running from a first winding roll to the beginning of the web of a new winding roll that is exchanged for the first winding roll, according to the preamble of patent claim 1.
  • splice devices which fix the end of the material web running to a processing machine at the beginning of the web of a new full roll. If the machine contains fixed holding devices for the winding rolls, the remaining roll is separated when the processing machine is at a standstill, the separated end of the running web is held in place and, after the separated remaining roll has been removed and a new roll has been inserted, is attached to the new roll, e.g. B. glued.
  • a generic device is known from DE-PS 34 40 107, which has a storage device for storing a supply of web material of the running material web, a Cutting device for cutting through the running material web and between the cutting device and the storage device has a driven suction roller, which takes up a part of the stored stock of web material and brings it into pressure contact with the outer circumference of the new roll in order to start with the new roll, which is provided with an adhesive strip is provided to make an adhesive connection.
  • the suction roll is arranged on a swivel arm which has a pivot point above the maximum outer diameter of the new winding roll and which extends substantially horizontally in the rest position.
  • the device shown there requires separate drives for clamping the running web, the movement of the storage device, the rotating and swiveling movement of the suction roll, the cutting device and for switching on the suction air.
  • the cutting knife must be moved out of its cutting position, since this is in the area of the running web during unwinding.
  • the invention has for its object to provide a generic device that requires a smaller number of individual drives and thus easier to control and less susceptible to interference.
  • the device according to the invention only requires four drives to be controlled separately, namely one for each pair of swivel levers, for the cutting process and for the holding element for holding the cut web end.
  • the invention enables the arrangement of the cutting device outside of the course of the web during unwinding, so that it can be permanently installed.
  • Claim 2 contains a particularly advantageous position for the cutting device, since so no overhanging, not held web residue is generated, which could lead to problems when laying on the full roll.
  • a traversing knife according to claim 3 requires little space with reliable function.
  • the blowing device according to claim 4 prevents the web residue between the pressing element and the holding element when it is placed on the outside of the full roll from loosening the web from the holding element and thus adversely affecting the gluing process.
  • Claims 5 and 6 contain structurally particularly advantageous embodiments of the invention.
  • 1 to 3 show a side view of the structure and operation of a device according to the invention.
  • FIGS. 1-3 The embodiment according to FIGS. 1-3 is designed for use on unwinding machines for winding rolls made of paper webs which are wound on cardboard tubes.
  • unwinding machines are often arranged together in a frame, so that the stripped webs are brought together to form a multi-layer web and then further processed together, e.g. B. in a sheeter for making sheets of paper.
  • the web is drawn off from the top of a roll upwards.
  • the winding rolls are held by guide heads which can be moved into the sleeve and are mounted in a frame or side stands.
  • the splicing device according to the invention is fastened to longitudinal beams 1 of the frame of the unwinding machine located above the unwinding point.
  • the longitudinal beams 1 extend on both sides of the web guide 2 at a distance above the maximum diameter of a full roll 3 and are supported on stands, not shown.
  • the unwinding position of a full roll 3 is determined by guide heads 4 which can be moved into the central sleeve.
  • the guide heads 4 are mounted in bearing blocks and connected to a brake.
  • a guide roller 5 which extends across the working width, firmly supports the drawn web 6.1, 6.2 in the horizontal to the subsequent processing machine redirects.
  • the splicing device contains a transport rod 7 which extends across the working width and is fastened at both ends to the free end of a pivot lever 8.
  • the pivot levers 8 are articulated on the longitudinal members 1 on both sides of the web guide 2 so as to be pivotable about an axis 9 which is offset from the vertical by the position of the guide heads 4 at a short distance from the web running direction.
  • a piston-cylinder unit 10 attached to the side members 1 acts as a swivel drive on the levers 8.
  • the levers 8 are dimensioned and so articulated outside the web width that the transport rod 6 below the horizontal web guide 2 from a rest position 11, which is located in the web running direction behind the guide roller 5 and above the maximum diameter of the roller 3, downward against the web running direction -
  • Fig. 1 to the left - to an end position 12 (Fig. 2) can be pivoted, which is in the web running direction in front of a full roll and above this, but still at a distance below the longitudinal beam 1.
  • a web holding element 14 extending across the working width is fastened, which in the present exemplary embodiment is designed as a suction bar with a row of suction cups which are open at the bottom.
  • the levers 13 are pivotally articulated on the underside of the side members 1 about an axis 15 located in the vicinity of the guide roller 5 and have an upwardly angled extension, at the end of which as a swivel drive, a piston-cylinder unit also attached to the side members 1 16 attacks.
  • a pressure roller 17 extending across the working width is fastened to the pivot levers 13, and approximately in the middle between the holding device 14 and the pressure roller 17, a downward blowing blow pipe 18 extends over the working width, which is also on both sides is attached to the levers 13.
  • the stroke of the piston-cylinder unit 16 and the conditions on the levers 13 are chosen so that the pressure roller 17 extends from the outer circumference of a full roller 3.1 with a minimum diameter to the free area between the maximum diameter of the roller 3 and that immediately below the longitudinal beam 1 located web guides 2 can pivot.
  • the holding element 14 In the swiveled-up end position, the holding element 14 is located directly next to the cutting line of a knife 19 traversing across the working width, the guide 20 of which is attached to the underside of both longitudinal beams 1 and is arranged at a sufficient distance from the web guide 2 of subsequently drawn webs that they do not disturbs.
  • the knife 19 with its guide 20 is arranged such that it - like the pivot lever 13 - can be pivoted outside by the transport rod 7.
  • FIGS. 1-3 1 shows the swivel arms 8, 13 in their rest position, in which none of the splice elements disrupt the course of the web 6.1, 6.2:
  • the transport rod 7 is in the rest position 11 in area kept clear of the guide roller 5 behind the web part 6.1 which has been pulled off upwards.
  • the swivel arms 13 are pivoted upward so that the pressure roller 17, the holding element 14 and the blow pipe 18 are located in the non-disturbing area above the course of the web 6.1 and below the web guide 2.
  • the diameter of the roll 3 decreases more and more and the course of the web 6.1 moves downward until a predetermined residual diameter 3.2 is reached, at which the unwinding process is stopped (FIG. 2).
  • the swivel arm 8 pivots clockwise, so that the transport rod 7 is moved from its rest position 11 and dips into the web 6.1.
  • the path 6. 3, 6. 4 shown in broken lines in FIG. 2 is reached.
  • the web part 6.4 lies both on the pressure roller 17 and also on the suction surfaces of the holding element 14 and the cutting line of the knife 19.
  • the levers 13 are pivoted up into the rest position shown in FIG. 1 and the unwinding machine can be accelerated to full working speed.
  • the adhesive seam 21 does not have to be positioned exactly, but only within a certain area. This enables a very simple roll preparation of the new roll for the splicing process and it eliminates the need for complex control devices that the adhesive seam 21 for producing the adhesive connection, for. B. by rotating the full roll.
