Definitions
- the invention relates to a method and a device for feeding a separating layer onto the surface of a metal strip to be wound up on a reeling device.
- a release liner in the form of e.g. Paper between the turns of a metal strip to be wound on a reel to protect the metallic surface of the metal strip is often carried out manually or with wooden sticks, but also with compressed air operated devices.
- EP 0 648 554 A1 discloses an apparatus and a method for loading paper between the windings of a metal strip during rolling up of the metal strip on a reel device.
- the paper is unwound from a separately arranged coiler of coils and fed to the metal strip.
- the paper is directed by a generated jet of air in a horizontal direction to the metal strip to be wound.
- DE 3 431 177 A1 a device for inserting paper strips during the winding of metal strips is known, wherein the paper strip running separately from individual rolls is fed to the sheet-metal strip rolls via an endless conveyor belt guided by a plurality of deflection rolls.
- the object of the invention is to improve a known device and a known method for supplying a separating layer to the surface of a wound on a reel metal strip in terms of reliability and safety.
- the object is achieved by the features of claim 1, wherein this is characterized in that the nozzle device is adapted to generate an air flow for sucking and adhering the release liner to the nozzle device.
- the invention provides a displacement device, for moving the nozzle device preferably together with the adhering to the nozzle device separation layer. With this displacement device, the nozzle device, together with the separating layer adhered to the nozzle, can be fed to any desired point over the entire length of the travel path and be positioned at a specific location.
- the displacement device is designed as a portable and / or length-adjustable feed arm on which the nozzle device is fixedly mounted.
- lateral adjustability for adjusting the feed arm can also be effected.
- the displacement device is designed as a rail on which the nozzle device can be moved.
- a solid leadership eg. B. in the form of a rail to mount stationary within the system, and to arrange only the self-propelled nozzle device on the rail movable.
- the advantage here is that the rail can be firmly anchored at both ends and that no moving parts are present, which are subject to wear. In the case of an accident only the nozzle device or the drive or the nozzle is to be replaced. This results in a much lower maintenance of this arrangement.
- the invention provides a control device for controlling the conveyance of the separating layer in the direction of the reeling device or of the metal strip to be wound up.
- this fully automatic control device it is possible, the adhering to the nozzle device separation layer uniformly over the entire necessary travel length in the direction of the coiler or to promote the wound metal strip.
- the release liner is stretched evenly and wrinkling is avoided.
- control device is designed for controlling the method of the nozzle device with the separating layer adhering thereto with the aid of the displacement device from a starting position to an end position in spatial proximity to the reeling device or to the metal strip to be wound during a starting operation , It is recommended according to a further embodiment feature of the present invention that the control device has a first synchronization device for synchronizing the removal speed (w) of the separation layer from the separation layer storage device with the Verfahrge- speed (v) of the nozzle device during the feeding process.
- This synchronization ensures that the separating layer adhering to the nozzle device is removed from the separating layer storage device under uniform tension and fed at uniform speed to the reeling device or the metal strip to be wound up, the synchronization ensuring that the separating layer is not separated during the feeding process the nozzle breaks off is still promoted by the air flow of the nozzle device beyond its current position in the direction of reel.
- the nozzle device is further designed for controlled conveying of the adherent separating layer by means of the Coanda effect in the direction of the air flow, which is directed to the reel device or the surface of the metal strip, and that the control device is formed, during the feeding operation, when the nozzle device is positioned in its end position, the feed rate (v) of the separating layer adhering to the nozzle device is in the direction of the reeling device or the catchment area of the reel to be wound up Adjust suitable metal strip by appropriately adjusting the removal rate (w) of the separation layer from the Trennlagen Eatein- direction.
- the advantage of this arrangement according to the invention is that the separating layer can adhere the separating layer with the aid of the Coanda effect which occurs at the nozzle outlet of the nozzle device and the separating layer is simultaneously conveyed in the direction of the air flow. That is, the separation layer is held on the nozzle device in a nearly vertical direction and simultaneously conveyed with the air flow in a nearly horizontal direction while always kept under tension, while avoiding wrinkling.
- the separation layer is released at the nozzle device and the air flow can further promote the separation layer on the nozzle device independently in the air flow direction to supply the separation layer an object, such as a metal strip.
- control device is designed to switch off the air flow of the nozzle device shortly after the beginning of a winding-up process in which the nozzle device preferably remains in its end position and that metal strip is wound onto the coiling device together with the separating layer. The previous feed operation is then completed successfully and the nozzle device is no longer needed at this point.
- control device has a second synchronization device, for synchronizing the winding speed (W) of the metal strip on the reeling device with the removal speed (w) of the separation layer from the separation layer storage device, after switching off the air flow of the nozzle device.
- the advantage of this synchronization is that after inserting the separating layer, the winding speed (W) of the metal strip is exactly synchronized with the separating layer in accordance with the removal speed (w) of the separating layer, so that tearing off of the separating layer is prevented. This is a uniform ges, complete application of the release liner throughout the winding process of the metal strip guaranteed.
- a separating device is provided for separating the separating layer at a desired location, and that the control device is designed to control the separating device at a suitable time, in particular at the end of the process operation.
- control device is designed to return the nozzle device in a return operation from its end position back to its original position.
- this control device also account for this restoring or adjustment, which are usually otherwise made by hand. The accident risk is thus reduced.
- An embodiment of the invention provides that the separating layer is a paper web, and that the separating layer storage device is a paper roll which is rotationally driven by a controllable drive and on which the paper web is wound up.
- control device is designed to suitably control the removal rate of the separation layer from the separation storage device by controlling the rotational speed of the paper roll during the delivery process.
- This control ensures a uniform feed of the release liner in conjunction with a controlled uniform unwinding speed and prevents premature tearing of the release liner from the coiler or from the nozzle assembly.
- the above object is further achieved by a method of feeding a release liner from a release liner to the surface of a metal belt to be wound with a coiler.
- the advantages of this method correspond to the advantages mentioned above with respect to the associated device.
- Figure 1 shows an apparatus for supplying a release liner in a starting position for the feeding operation
- FIG. 2 shows a nozzle with an adhering separating layer and the flow path of an air stream
- FIG. 3 shows the controlled displacement process of a nozzle device as the first part of the feeding process
- FIG. 5 shows the feeding of the separating layer into the feed area of the reeling device during the second part of the feeding process
- Figure 6 shows the winding process of the separating layer together with a metal strip on a common coiler mandrel
- FIG. 7 shows a separating device for separating the separating layer.
- FIG. 1 describes a device 50 for feeding a release liner 100 from a release liner 101 onto the surface of a metal belt 200 to be wound into a coil on a coiler 201.
- the release liner 101 comprises the release liner wound into a release liner 104 disposed on a coiler mandrel 103.
- the separation storage device 101 may also be a storage magazine for removing individual sheets of the separation layer.
- the initial portion 105 of the release liner is sucked by a compressed air driven nozzle device 300 disposed on a slider 400. The principle of operation of the nozzle device will be described in more detail below with reference to FIG. FIG.
- the separating layer 100 is conveyed with the air flow 302 in the flow direction 310.
- the device 50 is shown in an operating state during the first part of a feeding operation, with the feeding arm 401 of the feeding device 401 being shown in FIG Shifting device 400 together with the nozzle device 300 and the separating layer 100 adhering to the nozzle device 300 has moved at an advancing speed v from an initial position in the direction of the reeling device 201 or the metal strip 200 to be wound to an end position.
- a higher-level control device 500 contains a first synchronization device 510 for synchronizing the feed rate v of the displacement device 400 with the removal speed w of the separation layer 100 from the separation layer storage device 101. This first synchronization ensures that the separating layer neither breaks off from the nozzle during the first part feeding process nor is it conveyed by the air flow of the nozzle device beyond its current position into the direction of the reeling device.
- FIG. 4 shows the displacement device 400 with the nozzle device 300 and the separating layer 100 adhering to the nozzle device 300 in the end position.
- the starting region 105 of the separating layer is - during a second part of the feeding process - blown or conveyed with the air flow 302 of the nozzle device 300 in the direction of the coiler 201 or in the direction of a draw-in region 206 of the metal strip 200.
- the separating layer remains adhered to the nozzle device 300 by the air flow 302 generated at the nozzle device 300; see above description of Figure 2.
- the initial region 105 of the Tennlage is thereby blown to the extent in a collection region 206 between the wound metal strip and the coiler mandrel 203 as the release layer is released by the set removal rate w of the release liner from the separation storage device for a promotion ,
- the feed rate of the separating layer is thus the same as the controlled / set removal speed of the separating layer from the separating layer storage device.
- FIG. 5 shows the conveying of the separating layer into the catchment area 206 in more detail.
- the separating layer 100 adheres directly to the oiled reel mandrel 203 and is adhering to the coiler mandrel 203 with the rotational movement of the hackeldelds 203 supplied to the surface of the metal strip 200 and wound in the course together with the metal strip 200.
- the separating layer 100 can be directed into this catchment area 206 by means of a deflection device (not shown in this figure). As soon as the separating layer in the draw-in area is gripped by the metal strip and the coiler mandrel, the feeding process is completed.
- FIG. 6 shows that the reeling device 201 winds the metal strip 200 together with the penning layer 100 during a winding process subsequent to the feed operation.
- a common winding angle s which is between 30 degrees and 240 degrees
- the compressed air at the nozzle device 300 is turned off and the nozzle device 300 now moves from the end position 420 back to the starting position 410.
- the displacement device 400 with the nozzle device 300 describes the Shifting path L.
- a control device 500 is provided with a second synchronization device 520 for synchronizing the removal speed w of the separation storage device 101 with the winding speed W of the coiler 201, in particular while the nozzle device is switched off.
- FIG. 7 describes a separating device 600 for separating the separating layer, which is arranged between the reeling device 201 and the separating layer storage device 101.
- the separating layer 100 is separated with the separating device 600 at a predetermined or precalculated point.
- the separator 600 is controlled by the controller 500 so as to disconnect the separator layer 100 at the proper time so as to ensure that the metal tape 200 is covered with the separator liner 100 until the completion of the take-up operation.
