Definitions

  • the invention relates to a winding device for foils, in particular as an additive for long-splitting machines for foam blocks, and to a winding method.
  • Long splitting machines consist of an endless conveyor belt system with two deflection stations for soft foam blocks from 50 to 120 m in length and a cutting portal. Whose cutting unit is lowered by the desired film thickness after one block circulation. This makes the peeling process an economical and precise horizontal cutting process by eliminating the block return.
  • the film produced on the machine has a uniform cell structure. When using a block glued into an endless band, any desired length of film can be produced.
  • the film is wound up into a roll by a winding device, specifically in the form of a carrier roll winder which is driven in operation at the cutting speed of the long-splitting machine.
  • the cardboard winding cores are centered in conical locating bolts, which can be adjusted to the respective block width, and stored during the winding process.
  • the machine When the film roll has the intended diameter of, for example, 2 m, the machine is stopped, the film web is cut transversely and the full film roll is removed, after which the machine is started again.
  • This way of working leads to a certain productive dead time; the main disadvantage, however, is that there are variations in the thickness of the peeled film each time the machine is started.
  • the invention has for its object to provide a winding device for films, which allows the film rolls to be changed while film is being supplied.
  • two winding positions are provided between which the film roll is moved, namely a winding starting position in which the film roll grows to an intermediate size and an end position in which the final size of the film roll is reached. While the film roll is still in the end position, a new winding core is inserted into the starting position and the film web is pressed between the full film roll and the new winding core against the circumference of this winding core and then cut transversely. The winding core now put into operation winds up the supplied film while the full film roll is shut down and removed.
  • the first peripheral drive can consist of a conveyor belt.
  • the first and second peripheral drives can be driven by a common motor, each via its own clutch, so that these peripheral drives can be put into and out of operation individually and one after the other.
  • the extended splitting machine shown in FIG. 6 contains an endless conveyor belt system 1, two deflection stations 2, cutting units 3 for trimming the foam blocks 4, a cutting portal 5 for splitting off plates or foils and a table frame 10 for receiving the plates or foils.
  • the table frame 10 is adapted at the front end. 1 to 5 show the table frame modified to accommodate film 6.
  • Fig. 1 the rear parts of the film table frame 10 are indicated, which is height-adjustable via two spindle supports 11 and provides a passage for the foam block 4, as best seen in Fig. 5.
  • a deflection roller 13 for the film 6 a first circumferential drive 14, 15, a second circumferential drive 16, 17, 18 and first guides 19 are attached to the film table frame.
  • the first peripheral drive is designed as a idler winder and contains two rollers 14, 15 arranged next to one another, which drive in the same direction at the same peripheral speed are coupled to one another, and of which the roller 15 can be driven by a motor 20 via a belt transmission 21 with the interposition of a magnetic coupling (not shown).
  • the motor 20 drives the second peripheral drive 16 to 18, which contains two rollers 16, 17 and a conveyor belt 18, via a further belt transmission 22 and a magnetic coupling (not shown).
  • the translations are chosen so that the peripheral speeds of the peripheral drives correspond to the delivery speed of the film 6.
  • Second guides 29 are attached to a carriage 30, which can be moved along rails 31 between two positions I and 11, namely between a winding starting position I (FIG. 3) and a winding end position 11 (FIG. 4).
  • a threaded spindle 32 extends parallel to the rails 31 and works together with corresponding threaded nuts 33 in the carriage 30 in order to bring about the longitudinal displacement.
  • two guide rods 34 and a spindle 35 are also attached, in order to be able to move a cantilever arm 36, to which the second guide 29 is fastened, transversely to the direction of travel of the carriage in adaptation to the width of the foam block to be processed.
  • the first guides 19 can be adjusted in the same way with respect to their mutual spacing, namely here guide rods 24, a spindle 25 and cantilever arms 26 are provided, which carry the first guide 19 at their free end and along the rods 24 at their other end the spindle 25 can be moved.
  • a cutting device 40 is attached, which contains a swivel motor 41, a swivel arm 42 and a beam-like skid 43 with a knife 44 housed therein.
  • the skid 43 is normally pivoted away, as shown in Fig. 1.
  • the skid 43 is pivoted onto the rubber roller 15 of the first peripheral drive, as shown in FIG. 2.
  • the knife 44 is allowed to snap out in order to cut through the film 6 suddenly.
  • one or more drives 45 are provided on the runner 43 for suddenly moving the knife 44 out. If one accepts an obliquely cut end of the film 6, one can also provide a longitudinal drive for the knife 44.
  • FIG. 4 shows the cutting portal 50 in a schematic representation.
  • the angle of attack of the band knife 53 is adjustable by tilting the cutting unit 52.
  • the film 6 peeled off from the foam block 4 is guided over a wedge-shaped cutter bar 54 through the cutting portal 50 into the space between the foam block 4 and the underside of the table 10 until the deflection roller 13 (FIGS. 1 to 3) is reached near the end of the table, from where the film web is brought for winding over a winding core 7, which consists for example of a cardboard tube.
  • the second circumferential drive 16 to 18 is now stopped in order to lift the completely wound film roll 9 out of the guide 29 and to remove it.
  • the new, still small film roll in the initial winding position I grows until the intermediate size 8 shown in FIG. 3 is reached, after which the procedure is continued, as already described. It can thus be seen that the film 6 can be continuously wound up without interrupting the machine operation.
  • the film roll 8 When the film roll 8 is shifted from the initial winding position I into the winding end position 11, the film roll 8 rolls over the conveyor belt 18, from which an additional winding component is calculated in addition to the winding speed due to the belt drive.
  • the peripheral speed of the second peripheral drive 16 to 18 is reduced by the additional winding component during this position change phase.
  • a drive motor 20 which is controllable in terms of its speed and which is controlled to the required lower speed during the period in which the carriage 30 is being moved.
