Definitions
- the invention relates to a method for weaving a roll of a material web of a winding drum in a device, in particular a Tambourablagestation, wherein the winding drum is mounted with the winding start having a winding on both sides and rotatable in the device.
- the invention relates to a device, in particular Tambourablagestation, with a winding formed on a winding drum from a web, the winding drum is mounted with the winding start having a winding on both sides and rotatable in the device.
- This device is particularly suitable for carrying out said method.
- the material web is a paper web.
- it is also applicable to other courses, which must be handled similarly. These are, for example, but not exclusively, sheets of cardboard or tissue or films of metal or plastic.
- the inventive method is characterized by the possibility of automatic Abschwarts of the winding drum.
- the previous process steps for Abschwart a winding cylinder are now either completely eliminated, such as the cutting of the remaining rind, or automated so that the Abschwart can be performed without staffing.
- the method according to the invention is characterized by a not insignificant time advantage, since no additional transport paths have to be performed with the winding drum. Also, there is a commercial advantage because no additional equipment is required to transport the reel drum to a different position or level. With regard to the roll handling in the device, there is the advantage that no position for the skimming must be kept free, but all device positions can be re-populated immediately. This ensures, among other things, a smooth material flow in the device.
- the aforementioned unwinding direction of the winding drum is usually the opposite direction of the winding direction desselbigen.
- the rotation of the winding drum in the unwinding causes moreover that the winding start is unwound from the winding drum under all circumstances and due to the acting weight of its flow point falls vertically downwards so that it can be reliably detected by the at least one guide means.
- the guide device then performs the winding start together with the remaining web of the winding in a arranged below the device Committee.
- the known per se reject container also called pulper in professional circles, can have a shaft with a temporarily closable manhole cover.
- the winding roll stored in the device is rotated in the unwinding direction by means of the drive device at least for so long, preferably only until the remaining material web of the roll runs automatically from the winding drum during its rotation as a result of the acting forces. Basically, it is only necessary to turn the wrapping drum until it runs on its own. Thus, the required drive power for the Abschwart can be significantly reduced and provide a time advantage.
- the guide device is arranged at least initially vertically below or substantially vertically below the discharge point of the winding start to the socket.
- the winding beginning which has run off the winding as a result of the rotation of the winding drum is guided by the guide device, at least over an initial stretching region, preferably to the reject container.
- a noticeable simplification of the guide can also result if the expired winding start is guided in a further embodiment of the guide device at least over a vertical distance range away.
- the object of the invention is achieved in a device of the type mentioned in that at least one preferably controllable / controllable drive means for at least initial rotation of the winding drum mounted in the device is provided in a unwinding that at least one guide means for detecting the resulting from the winding the rotation of the winding drum at an expiration point expired winding start is provided and that the guide means is designed to guide both the expired winding start and the remaining material web of the roll in a arranged below the device reject container.
- the drive device preferably comprises a preferably controllable / controllable drive unit, in particular an electric motor, and at least one drive element which can be acted upon by the drive unit and can be brought into engagement on the winding drum, in particular a friction wheel, a drive belt or the like. Due to its operational reliability and the associated runnability, this type of drive device contributes to outstanding functionality of the device.
- the guide means may be at least initially arranged vertically below or substantially vertically below the discharge point of the winding start to the socket.
- the guide device comprises at least one funnel-shaped inlet area with at least two walls arranged at a funnel angle and a channel-shaped main area with at least two preferably parallel or approximately parallel walls.
- the guide device thus essentially corresponds to an open guide box and is characterized by a given functionality in a simple structure, since, for example, the funnel-shaped inlet area allows an independent detection of the beginning of the winding.
- the means may comprise at least one preferably controlled / regulated drivable pair of rollers or brush pair, which clamps the winding start on the inside.
- the guide device can be arranged stationary or movable by means of at least one movement device.
- a stationary arranged guide device is preferably arranged vertically below or substantially vertically below the discharge point of the winding start to the socket.
- a movably arranged guide device is preferably movable by means of the movement device at least between a detection position in which the winding start is detected by it and a dispensing position in which the winding start and the remaining material web of the winding is dispensed directly or indirectly into the reject container.
- the movement device itself can comprise at least one winch arranged at the beginning and at the end of the guide device and preferably controllable, wherein the guide device is preferably guided on both sides by means of at least one guide system, in particular guide rails.
- the Guide system can in this case be movable at least between a rest position and a guide position, so that there are no collisions with other moving components in the area of the device, such as winding rolls and the like.
- it may comprise at least one linear guide arranged at the beginning and at the end of the guide device and preferably controllable / controllable, wherein the guide device is preferably guided over at least a vertical distance region.
