Definitions
- the invention relates to a device for unwinding sheet material according to the preamble of claim 1.
- Devices for unwinding web material are usually upstream of web-processing machines. Such machines are, for example, hose machines that produce hoses of sheet material, valve sheet devices for sack making machines or printing presses of any kind. Under sheet material can be understood in this context inter alia, flat or tubular webs.
- Such devices for unwinding sheet material are already known in various forms.
- a particularly simple ⁇ us enclosuresform which is already widely used, has an unwinding for receiving a winding shaft for web-shaped material, for example, fabric rolls.
- the unwinding point known here consists of two parallel lifting rockers, in which the winding shaft (with the winding applied thereto web-like material) is added.
- the winding shaft is mounted laterally in folding bearings. Coaxial with the winding shaft fixed via the folding bearing becomes a pneumatic brake tethered. The required web tension can be generated via the pneumatic brake and the machine can be stopped to change the reel.
- This known device for unwinding web-like material has the advantage that it is simple and robust. However, it has the disadvantage that the replacement of the winding shafts is relatively time consuming.
- the object of the invention is to develop a simply constructed device for unwinding web-like material in such a way that on the one hand it is still simple and inexpensive, but on the other hand enables a simple, quick and safe change with regard to the roll change.
- the device for unwinding web-like material has a first and at least one second unwinding location, in which first and second reels of the web-shaped material are rotatably storable, one unwinding station being stationary and the other unwinding location being movably arranged in the device.
- the movable unwinding point on a brake which can be coupled via a gear pair with the wound winding of the web-shaped material.
- the movable unwinding may consist of a pivotable winding transport lever pair.
- the full winding is placed, while at the same time stores the almost unwound winding on the stationary unwinding and unwound from this.
- a brake is advantageously arranged laterally on a winding transport lever of the winding transport lever pair, this being connected to a shaft mounted in the winding transport lever on which a toothed wheel can engage a second gear of a gear pair which is received on the winding shaft of the winding transport lever pair Wickels is arranged.
- the tooth shape and / or arrangement of the gears of the gear pairing is chosen so that when inserting or transferring the coil, the gears of the gear pair for coupling or decoupling substantially radially on and decouple.
- the gear pair in the winding transport lever can be covered by a cover.
- the cover of the gear pair may consist of a unilaterally pivotally hinged lid whose pivotable side can be fixed by means of magnets in the closed position. After transfer of the winding shaft in the stationary unwinding position, the cover opens automatically when returning the Wickeltransporthebelpases.
- the stationary unwinding point Since, when transferring the roll to the stationary unwinding station, the brake present on the movable unwinding station is no longer in engagement with the reel, the stationary unwinding point has a coating of a material that decelerates the rotation of the reel shaft in the region of its reel shaft receptacle.
- a sufficient braking force is already impressed on the winding, so that further braking devices are superfluous.
- a friction brake directly interacting with the winding shaft can be arranged at least on one side of the stationary unwinding location.
- FIG. 1 a simplified illustration of a device 10 for unwinding sheet material 12 is shown.
- the web-shaped material is withdrawn by at least one pair of delivery rollers not shown here in detail and supplied to a web-processing machine, also not shown.
- Such web-processing machines may be a printing machine, a tube or processing machine, among other things for paper, plastic or plastic fabric, which is usually made of polyolefin, or a sack or bag making machine that makes sacks or bags.
- the unwinding device has a machine frame 14, in which a first unwinding point 16 and a second unwinding point 18 are arranged.
- the first unwinding point consists of a pivotable Wickeltransporthebelpress 16, in which a new roll with web-shaped material 20 can be inserted.
- the winding transport lever pair 16 is pivotable about a pivot shaft 22 by means of a piston-cylinder arrangement 24, which is connected on one side to the machine frame 14 and on the opposite side to the winding transport lever pair.
- About the winding transport lever pair 16 of the winding 20 is pivoted from a receiving position shown in Figure 1 (dash-dotted line) in an unwinding position (solid line).
- FIG. 2 In the illustration according to FIG. 2 moreover, two different unwinding possibilities for the web-shaped material 12 are shown.
- the web-like material In one of the Abwickelities the web-like material is guided over the drain rollers 26 and 28, while in the alternative position, the web-like material 12 is withdrawn only via the take-off rollers 28.
- the winding 20 In both unwinding positions, the winding 20 can be transferred from the winding transport lever pair 16 to the stationary unwinding point 18 without the unwinding process having to be interrupted.
- FIGS. 3 and 4 In each case, a detail of the Wickeltransporthebelpases 16 is shown in two positions.
- a winding transport lever In the schematic sectional view according to FIG. 3 is shown part of a winding transport lever.
- a shaft 32 In a box-shaped receptacle 30, which is part of the winding transport lever not shown here, a shaft 32 is rotatably received on the outside of the winding transport lever in also not shown, a brake, in the present case, a pneumatic brake, arranged and fixedly connected to the shaft.
- a gear 34 is arranged on the shaft. This gear 34 meshes with a arranged on the winding shaft 36 of the recorded coil 20 gear 38th
- FIG. 3 It is shown how the winding shaft 36 is moved in the direction of arrow a when placing the roll 20 on the winding transport lever pair in the direction of the shaft 32.
- the gear pairing of the gears 34 and 36 As in FIG. 3 shown, engaged.
- the brake which is not shown here in detail, arranged on the winding transport lever 16 acts on the winding shaft 36 and thus on the winding 20, so that inadvertent rotation of the roll 20 due to uneven weight loading is prevented. Furthermore, the necessary web tension is maintained even during the removal of the sheet material 12 by the coupled brake.
- the toothing of the gears 34 and 38 is selected such that the gears engage in insertion of the winding shaft 36 in the winding transport lever pair 16 without further problems with each other.
- the tooth flanks are formed somewhat obliquely than in a conventional involute toothing, so that a, as shown in Figure 3 and FIG. 4 results in more acute-angled tooth shape.
- a cover 40 is provided, which is closed in a solid line and opened in dotted line.
- the cover 40 is hinged on one side about corresponding hinges 42. On the other side it is held by a metallic projection 42 with a magnet 44.
- the magnetic force is in this case adjusted so that with a corresponding pivoting of the Wickeltransporthebelpass 16, as in FIG. 4 is shown, the self-contained lid 40 automatically pivots in the direction of arrow b, so that the winding shaft 36 with pivoted cover 40 to the stationary unwinding point 18 (see. FIG. 2 ) can be handed over.
- FIG. 5 schematically a part of the winding shaft 36 is shown, which is stored here in the receptacle 46 of the stationary unwinding point 18.
- the winding shaft with the largely unwound winding 20 are slowed down otherwise.
- a slip-resistant friction lining for forming a friction brake 48 is provided on the receptacle 46.
- This covering may consist of a plastic or a natural material, such as leather, which has a high coefficient of friction in a pair of materials with steel.
- an additional hand-operated brake 50 is disposed laterally at the stationary unwind location.
- This manually adjustable brake 50 consists of two pivotable clamping jaws 52 which extend from the dashed position in FIG. 5 in an engaged position (solid line) are pivotable and there via a manually zudusbaren screw mechanism (not shown here) is adjustable.
