Description
- This is a nationalization of PCT/EP2004/004803 filed May 5, 2004 and published in German.
- The present invention relates to a winding device according to the preamble of the
main claim 1. Winding devices are known from a multitude of published prior art of which only the patent application WO 99/06313 and US 5848761 have been mentioned as examples. Winders are usually categorized as contact winders and turret winders. - Among these winders the following devices must be highlighted here:
- Devices for winding web-shaped material—particularly film—on winding cores, that are provided over at least one device for electrostatically charging the web-shaped material.
- The present invention is based on these devices.
- In the devices described in the patent applications U.S. Pat. No. 4,852, 820 and DE 102 02 462, the device for electrostatically charging the web-shaped material is used for holding down the web-shaped material on the initial winding sleeve. In this manner it is possible to hold down the initial section of the web-shaped material on a winding core without the help of adhesives. In technical jargon, this method is called “adhesive-free initial winding” and has high economic value because an initial winding process of such type can be executed fully automatically and additionally without the application of solvents on the web-shaped [handwritten correction made to the source; originally said “band-shaped”] material.
- As a rule and also in the patent application DE 102 02 462, the afore-mentioned device for electrostatically charging the web-shaped material is usually formed as a beam-shaped electrode that can overcoat the width of the web-shaped material. In all applications and published prior art, they are illustrated in immediate proximity to the winding core and they charge the film with an electrical field when they reach the winding core.
- The spatial proximity to the winding core is highly recommended since the strength of electrical fields strongly reduces as the distance from the electrode increases and ideally the biggest possible field effect should be available during the initial winding process. Therefore, the patent application DE 102 02 462 recommends arranging the means for electrostatically charging the web-shaped material as close as possible to the initial winding position, and/or within a small close and constant distance from the winding core during the initial winding process by means of a special displacement of the position of the electrode.
- The devices specified in the preamble of the present patent application have proved to be of value during the “adhesive-free initial winding process.” However, like all winding devices of prior art, they exhibit disadvantages during the entire winding and cutting processes when several layers of film or film tubes have to be wound up. In this connection, it must be emphasized that these requirements are by no means unusual because winding devices often wind up the film that is just extruded from blown film extrusion plants. This film leaves the die head as film tube and is wound up either directly as a film tube or is severed into two film webs that are frequently wound up as double layers. In the following description these multi-layered material webs are also called layers of material webs. Film rolls are also known in which more than two material webs are wound up.
- The reason for the afore-mentioned disadvantages is that at high winding speeds air gets trapped and is subsequently wound up in between the said film layers or in the film tubes. This gives rise to unattractive, too voluminous and telescopic film tubes, thus finally even causing the interruption of the winding processes. In case of film tubes, the shape of the initial section of the film during its transport through the winding device is referred to, partly metaphorically as “fish mouth.” Additional defects with regard to quality come into existence in case of too uneven and unattractive slits at the cutting point (while cutting off the film web perpendicular to its conveying direction) when air gets trapped between the layers that are to be cut. Even film tubes are referred to as multi-layered material webs in this patent application.
- The objective of the present invention is to suggest a device that reduces the chances of air getting trapped in-between multi-layered, web-shaped material when the latter is being wound up.
- This objective is achieved by
- arranging at least one device for electrostatically charging the web-shaped material in such a manner with respect to the web-shaped material and the winding core that it exposes the web-shaped material to an electrical field before it reaches the winding core.
- The ability of different layers of material to join one another with great stability when charged electrostatically is greatly surprising. Furthermore, it must be mentioned that for improving the initial winding process an electrical field can also be used on the winding core without any interference from the means according to the invention for electrostatically charging the web-shaped material.
- In the sense of this invention a winding core can be a winding sleeve or a different body shaped like a rod or a circular cylinder.
- In case of different types and sizes of winders, it is advantageous to insert the film at different mounting positions and distances from the winding sleeve along its transport path. However, in general, it is useful if the electrical field joins the film layers to one another before they reach the cutter.
- In case of a contact winder, the roller that guides the film before it reaches the winding core is the contact roller.
- The process of charging the film electrostatically while passing through the rollers has proved to be greatly valuable.
- Modern winding devices often have a multitude of such suitable deflecting or web guide rollers. These can also be arranged upstream to the winding device on the transport path of the web-shaped material.
- Additional preferred embodiments of the invention are specified in the present description and in the claims. The individual figures of the drawing illustrate:
-
FIG. 1 a perspective view of a storage device according to the invention -
FIG. 2 a perspective view of the mounting device of the winding device -

FIG. 4 a perspective view of the parts of the winding device that guide the winding sleeves -
FIG. 5 the same perspective view as illustrated inFIG. 4 in which the winding sleeve is located in the winding position. -
FIG. 6 a view of a deflecting roller on which the means according to the invention are provided for electrostatically charging the web-shaped material. -
FIG. 1 illustrates astorage device 1 according to the invention that comprises of adrum 2 suspended between theholding plates 3 on the front sides of the drum. Theplates 4 which are connected to one another by thetraverse member 5 form the front sides of thedrum 2. Theplates 4 comprise ofrecesses 6 for mounting thewinding sleeves 7. The torsional moment for the rotation of thedrum 2 is provided by both thedrives 10. Twodrives 10, of which only one can be seen completely, are used in this embodiment since the working width of the winder is relatively big. Thedrives 10 comprise of themotors 8 and thegear unit 9. - The
insert sheets 11 for inserting thewinding sleeves 7 into thestorage device 2, thelinear cylinder 12, theknife protection 13 and thetraverse member 14 can also be seen inFIG. 1 . Theaxis 41 of thedrum 2 is formed by thedrum traverse member 5, which connects theplates 4 to one another. The transport of the winding shaft into thestorage device 1 is carried out by the rotation of thedrum 2 around theaxis 17. -
FIG. 2 illustrates an additional functional element of the winder—themounting device 15 for the winding shafts. The most substantial parts of themounting device 15 are the holdingarms 16 that can be swiveled around theaxis 17 around which thecontact roller 18 also rotates. The force required for the swiveling movement is provided by thepneumatic cylinders 19, which are hinged at the connecting points 20 to the holdingarms 16 and at the connecting points 21 to the machine frame that is not illustrated here. - In the upper section of the holding arms, the
holding heads 22 can be seen that can take over thewinding shafts 7 from thestorage device 1. InFIG. 2 , theholding heads 22 are located at the transfer position at the upper end of theholding arm 16. The winding shaft is placed in the mounting position 23 of theholding head 22 and is locked in place with the help of thelock 24. Thelock 24 is illustrated inFIG. 3 b. It is shaped to suit its purpose of locking thewinding shaft 7 in place. Thecylinder 25 pushes the lock over thewinding shaft 7, thus locking the latter. The force of thiscylinder 25 is transferred by means of the connecting device 30, as illustrated inFIG. 3 a. Thecylinder 25 is attached to the holdinghead 22. - The holding heads 22 can be displaced along the holding
arms 16 in the vertical direction. In this manner the windingshaft 7 can be placed on thecontact roller 18. Thisposition 34 of the winding sleeve—the so-called initial winding position of the illustrated contact winder—is illustrated inFIG. 4 . The force for changing the position of the holding heads 22 in relation to the holdingarms 16 is applied by thecylinders 26 that transfer the required force onto the holdinghead 22 using therod 27 and thelinkage 18. -
FIGS. 4 and 5 illustrate the entire progression of a windingsleeve 7 in a contact winder. Thestorage device 1 and the mountingdevice 15 are also illustrated in this connection. In addition to the components already illustrated inFIG. 1 to 3, the bearingrail 27 and the layingarm 28 are also illustrated here. On the bearingrail 27, which is designed to be continuously straight, the winding shaft is located in its windingposition 31 illustrated inFIG. 5 . After the old roll has taken up sufficient web-shaped material, it is moved along the bearingrail 27 of a holding and transport device, that is not illustrated here, up to theholding point 32 of the layingarm 28 that can be swiveled around theaxis 29. With the help of this layingarm 28, the heavy winding sleeve supplied with web material can be pivoted away onto another transport device. The force required for this purpose is applied by a cylinder (not illustrated here) that is hinged onto the bearingeye 33. - Additional details of the winding process and the transport of the winding shafts through a contact roller are known to those skilled in the art and hence do not require a more elaborate explanation.
- The material web or the film 35 is illustrated only in the
FIGS. 4 and 5 , where the initial section of thefilm 36 can be seen only inFIG. 4 . Thelast deflecting roller 37 located before the deflectingroller 18 is also illustrated. Opposite to it, theelectrode 38 is located, which is attached to the machine frame (not illustrated here) usingholders 39. The electrode enables the advantageous application of an electrical field to the film tubes. The adhesion of the two tube walls to one another is referred to as “blocking.” The positioning of thiselectrode 38, which is an embodiment of the means for electrostatically charging the web-shaped material is the object of the present invention. - Therefore
FIG. 6 illustrates yet another view of a deflectingroller 39 of an additional embodiment of the present invention on which means are provided for electrostatically charging the web-shaped material. - These means comprise of the
electrode 38 and the mountingdevice 42. Above this deflectingroller 39, thelast deflecting roller 37 is located upstream in the transport direction z of the web-shaped material. The outlined guiding of the deflecting roller is marked with thereference symbol 43. It can be provided with additional means for electrostatically charging theroller 39 in order to increase the potential difference of theelectrode 38 or to provide the film with a potential independent of theelectrode 38. The afore-mentioned blocking effect of the two tube walls according to the invention can also be achieved by the exclusive application of charge to the roller. The web-shaped material guided over the deflectingroller 39 comprises of the inner 40 and the outer 41 film web.
