Definitions

  • the invention relates to a method for connecting a first material web running to a processing machine with the start of a second, wound material web.
  • German publication 2 430 514 Another solution can be found in German publication 2 430 514.
  • double unwinding is assumed, the material webs being fed to drives which are mounted so as to be displaceable in a drive frame, which drives are arranged on both sides of a central connecting station and can be moved thereon or moved away therefrom. Again, the effort is quite high and a lot of space is required.
  • the lanyard e.g. an adhesive strip can be applied in the machine, but this is usually particularly expensive.
  • the invention is based on the object of proposing a method suitable for connecting a first, running material web to the start of a second, wound material web, with which a secure connection of the two material webs can be achieved in a simple and inexpensive manner in the shortest possible time. Furthermore, the invention is based on the object of providing a device for preferably carrying out the method which, above all, can be used more universally with a simple structure.
  • the fast web connection is achieved according to the invention in that the first web of material, viewed in the direction of travel, is first cut behind a stored web section when the processing machine is at a standstill and the separated web section is then at least partially buffered, after which the web section is brought into pressure contact with the processing machine and when the processing machine starts up the end of the temporarily stored web section and the tapering start of the second material web are connected to one another by releasing the temporarily stored web section.
  • connection is obtained where the connecting element, e.g. an adhesive can be applied outside the machine to the incoming material web and thus this material web can be largely prepared for the subsequent connection.
  • the connection can be established in a very short time and is also very inexpensive, since there is no need for complex double unrolling and any synchronization device.
  • the temporarily stored web section is first wound up and unwound again after the pressure contact with the second material web.
  • the connection can be accommodated in a confined space, regardless of how large, e.g. the outer diameter of the winding roll having the second material web.
  • a correspondingly long piece of the end of the first material web is temporarily stored and processed in such a way that the end of the temporarily stored tape section and the beginning of the second material web essentially lie one above the other, so that a quick and safe Connection is possible without this being impaired by a freely hanging end piece of the first material web.
  • a device for connecting a first, running material web with the start of a second material web running in from a replacement winding roll comprises a stand carrying the replacement winding roll and a storage device for storing a supply of web material, as well as a cutting device for severing the web of material, according to the invention providing that in In the web running direction between the cutting device and the storage device there is arranged a transfer member which receives at least part of a separated web section of the first material web and which can be brought into pressure contact with the outer circumference of the replacement winding roll.
  • the transfer member is designed as a rotating suction roller and is arranged on a swivel arm mounted in the stand.
  • the suction roll performs the task of a buffer to temporarily hold the separated end piece in a corresponding length, and for as long as the wound web piece is unwound again after contact pressure with the replacement winding roll until the end of the temporarily stored web section with the one Adhesive point provided at the beginning of the second material web coincides.
  • the articulation point of the swivel arm is immediately below the storage device and essentially above the max. Outside diameter of the supply roll is arranged.
  • the lateral insertion of the replacement winding roll is facilitated in that at least one of two opposite support beams can be pivoted about an essentially horizontal axis.
  • all winding roll diameters can be accommodated from the same position. The entire operation can be carried out from the ground, in particular the web insertion. In addition, such unwinds can be set up completely over the hallway, ie without complex foundation work.
  • the universal applicability of the device is achieved in that the device or a plurality of devices which follow one another directly between the uprights of the machine frame have a roll loading or removal both in and transversely to the direction of travel of the material webs, and that the or the lateral loading facing support beams of the support frame are pivoted up.
  • a device is obtained in which the loading can take place both in and transversely to the web running direction, regardless of whether one or more unwinding devices are set up one behind the other.
  • By supplying the supply rolls from the side they can be retracted and picked up at the same time, which results in significantly shorter idle times. Since, moreover, only the support beam facing the loading side is designed to be pivotable, whereas the respectively assigned other support beam is not designed to be pivotable, this also results in a considerably simpler structural design.
  • the entire operation can be carried out from the ground, in particular the introduction of the web. Since the unwinding devices are set up completely above the floor, there is naturally no need for complex foundation work.
  • the unwinding devices are equipped with a large number of additional devices, which can range from the simplest application to fully automatic reel loading, connection of the expired web with the new reel, empty tube removal and empty tube removal.
  • the space in the upper area of a device according to the invention is skillfully used to arrange and support the support frame. It is provided that the pivot axis of the pivotable support beam or beams is arranged directly above a longitudinal beam connecting the uprights to one another on the support frame which is pivotally mounted on one side and supported on a crossbar on the other side.
  • the pivotable support beam or beams are held in the raised position by a releasable latch.
  • a longitudinal member 2 is fastened to a stand 1 set up above the floor, on which a bearing 3 is arranged for the transversely displaceable mounting of a support frame 6 supported on rollers 4 on a crossbar 5.
  • support beams 7 are arranged on opposite sides, one of which can be pivoted about a horizontal axis 20 for the lateral insertion of a winding roller 11 via the adjustment range indicated by dash-dotted lines.
  • the winding roll 11 is rotatably mounted on the support beam 7 via piston rods 8 and clamping heads 9 by means of clamping sleeves.
  • the material web 13 running therefrom is guided between a transfer member designed as a circumferentially drivable suction roller 14 and a guide roller 15 to a storage roller 16 of a storage device.
  • the storage roller 16 can be moved in the indicated arrow directions 18 by drive means, not shown.
  • a clamping device 19 is arranged on the longitudinal beams 2.
  • the suction roller 14 is rotatably mounted on a swivel arm 22 which can be swiveled via a cylinder piston unit 23, which is only indicated.
  • a cutting device 27 is provided for severing the material web 13.
  • the material web 13 leads behind the storage device to a processing machine, not shown, e.g. a cross cutter.
  • the mode of operation of the device is as follows: starting from the starting position shown in FIG. 2, the material web 13 runs from a full winding roller 11, specifically along the guide roller 15 and the storage roller 16.
  • the swivel arm 22 is pivoted upward, so that the suction roller 14 is not in contact with the running material web 13.
  • the clamping device 19 becomes effective as indicated in FIG. 3.
  • the storage roller 16 is adjusted to the left in the indicated arrow direction 31, while the suction roller 14 remains in its position.
  • an elongated “flag” is generated between the suction roller 14 and the storage roller 16 for the gluing process explained in more detail below.
  • the material web 13 is cut device 27 is cut so that the remaining roll can be removed when the cross cutter is at a standstill.
  • the previously extended part of the material web is wound up by the suction roller 14 which is driven in the direction of the arrow 31, and at the same time the storage roller 16 is moved back into its original starting position.
  • the suction roller 14 is then moved downward in the indicated arrow direction 32 via the swivel arm 22 until the suction roller 14 comes to rest on the outer circumference of a newly inserted replacement winding roller 33.
  • the position of the beginning of the second material web 35 provided with an adhesive strip 34 and the length of the temporarily stored web section of the first material web 13 are matched to one another such that the beginning of the second material web and the end of the first material web 13 coincide.
  • Fig. 7 it is indicated with dash-dotted lines that in the same way replacement winding rollers 36 with a diameter that is substantially smaller than that of the replacement winding roller 33 can be treated, simply by the fact that the swivel arm 22 swings further downward. It goes without saying that a correspondingly long piece of the first material web 13 is temporarily stored via the suction roller 14 in accordance with the fixed position of the adhesive strip 34 and the respective diameter of the new replacement winding roll.
  • FIG. 8 shows how the beginning of the second material web 35, after releasing the clamping device 19 and starting up the processing machine, is connected to the end of the first material web 13 via the adhesive strip 34, and how the new material web is shown in FIG. 2 Way to the processing machine is running. Since the acceleration of the replacement winding roll is achieved only from standstill by friction with the material web 13, no drive and synchronization devices are required for the replacement roll.
  • the swivel arm 22 is finally pivoted upward about the articulation point 21 according to FIG. 9, so that the starting position shown in FIG. 2 is again assumed.
  • FIG. 10 shows a modified unrolling device which, strictly speaking, consists of three unrolling devices one behind the other.
  • a longitudinal beam 2 is fastened, on which a bearing 3 is arranged for the transversely displaceable mounting of a supporting frame 6 supported on rollers 4 on a crossbar 5.
  • support beams 7 are arranged on opposite sides, one of which can be pivoted about a horizontal pivot axis 20 for the lateral insertion of a winding roller 11 via the adjustment range indicated by dash-dotted lines.
  • a supply roll 11 is rotatably mounted on rods 8 and clamping heads 9 by means of clamping sleeves.
  • the material web running away from this is designated by 13.
  • the material web 13 leads to a processing machine, not shown, e.g. a cross cutter.
  • the supporting frame 6 can be adjusted on the transverse supporting axis by adjusting means, for example pinion and rack, via adjusting motors transverse to the web running direction in order to be able to adapt to material webs of different widths.
  • a detachable latch 37 is provided to hold the support beam 7 in its pivoted position.
  • the support frame 6 is pivoted so that the support beams 7 are vertical, the support beams 7 being extended downwards until the expired supply roll comes to rest on a conveyor provided there.
  • the supporting beams are retracted and pivoted into the position shown in dashed lines.
  • a new supply roll is fed in from the side and the supporting beams are then swiveled back, i.e. in the vertical position, and then brought up to the appropriate and necessary height so that the clamping heads present there can be inserted and fastened on both sides in the axle sleeves of the new supply roll.
  • the new supply roll is raised by actuating the lifting device until it has reached the predetermined end position.
  • the new supply roll is prepared for the splicing and connected in a known manner to the end of the previously unwound material web.
