Description

The invention relates to a device for winding partial material webs on winding tubes to partial material web rolls, which are arranged in at least two winding position groups, wherein the Teilmaterialbahnrollen are stored in winding stations, each consisting of two mutually parallel winding blocks, and wherein at each winding block a retractable into the winding tube , is arranged connected to a rotary drive and movable guide head, wherein at least one sliding line for the electrical supply of the rotary drive of the guide head and the rotary drives of the guide heads is present.

Such a device is known from GB 23 13 111 A known, which provides for the linear positioning of winding blocks, the electrical supply via a rail-like conductor rail, said adjusting device and motor are in fixed structural relationship to each other.

Another device for winding partial material webs is for example from the German patent application DE 40 12 979 A1 known. The rotary actuators of such a device are supplied via Kappelschleppanlagen or laid in energy supply chains lines with electrical energy and signals. This type of supply is associated with a considerable effort for the design, higher production costs and a corresponding space requirement.

The invention is therefore based on the object, a device of the type mentioned in such a way that the said disadvantages of the state of

Technique noticeably reduced, preferably even completely avoided.

This object is achieved in that the winding position groups axially offset from each other at different circumferential positions on a common and driven central roller and the movable guide head is arranged radially to the central roller and that at least one, preferably each winding station between a working and a waiting position by means can be pivoted to the pivoting and that at least one conductor line for the electrical supply of the device for pivoting the winding station or the means for pivoting the winding stations is present.

The object of the invention is completely solved in this way.

The invention has the advantage that the power required for operation can be transported in a space-saving manner to the at least one rotary drive of the associated guide head. The electrical power is transmitted via conductor rails and pantographs. Also, the configuration of the device designed overall easier and cheaper.

Another advantage of the solution is that the rotary actuators regardless of their number of pieces via a conductor rail system are supplied with electrical energy. This solution causes relatively low costs, especially for a larger number of rotary actuators. The rotary actuators can also be replaced without loosening an electrical connection.

In a first embodiment according to the invention it is provided that at least one, preferably each winding frame carries on its upper side a carriage movable radially to the central roller together with a device for its movement, on which the guide head is arranged with its rotary drive, and that at least one conductor line for electrical supply the means for moving the carriage or the means for moving the carriage is present. Again, there are the aforementioned advantages of the invention.

Furthermore, at least one sliding line for transmitting signals coming from a control unit to the rotary drive of the guide head or the rotary drives of the guide heads, to the means for moving the carriage or the means for moving the carriage and / or to the device be present for the rotation of the winding station or the means for the rotation of the winding stations. The transmission of signals coming from the control unit to the respective receiver preferably takes place via a bus system, in particular an AS interface, a CAN bus or a Profibus. Over other contact rails and pantographs so also the signals are sent by means of a bus to the device components or device assemblies. This does not preclude modulating the signals to the voltage for the power supply in order to save an additional line for signal transmission.

Furthermore, the device according to the invention can also comprise at least one monitoring device, which can be supplied with energy and / or signals via at least one contact rail.

With regard to a practical implementation of a roller type, the at least one conductor line is preferably arranged below the winding block in such a way that the at least one rotary drive can be supplied directly or indirectly with energy and / or with signals. The sliding line runs in this case in an ideal manner transversely to the web running direction of the partial material web.

Also, the at least one conductor line in a roller type is preferably arranged in the region of the winding frame, preferably laterally on the winding frame, that the at least one device for moving the carriage directly or indirectly with energy and / or signals can be supplied. The conductor rail runs in an ideal way along the winding frame.

Moreover, the at least one conductor line is preferably below the Wickelbocks arranged that the at least one device for pivoting the winding station is directly or indirectly supplied with energy and / or with signals. The sliding line runs in this case in an ideal manner transversely to the web running direction of the partial material web.

With regard to a practice-oriented implementation of another type of scooter, the at least one conductor line is preferably arranged above the winding trestle so that the at least one rotary drive can be supplied directly or indirectly with energy and / or with signals. The sliding line runs in this case in an ideal manner transversely to the web running direction of the partial material web.

In the case of a further type of roller, the at least one conductor line is preferably arranged in the area of the winding block, preferably laterally on the winding block, so that the at least one device for moving the carriage can be supplied directly or indirectly with energy and / or with signals. The conductor rail runs in an ideal way along the winding frame.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.

The device 1 is preceded by a longitudinal cutting device 6, in particular a roller cutting device, in the running direction L (arrow) of the partial material webs 2. It has a feed section 7 in which a usually machine-width material web 8, for example a paper or board web unwound from a jumbo or mother roll, is fed. The material web 8 then passes through a cutting section 9, in which it is divided by known per se, such as cutting blades 10, 11, into a plurality of partial material webs 2. In this case, at least one, substantially transversely to the running direction L (arrow) of the partial material webs 2 extending grinding line for the electrical supply to the motors of the cutting blades 10, 11 may be present.

The cutting blades 10, 11 cut the subsequently guided over a further roller 12 web 8 in this case in the longitudinal direction. For this purpose, a certain tensile force is required, which is applied substantially via the central roller 5. The partial material web rolls 4 formed on the winding cores 3 are pressed so strongly against the surface of the central roll 5 when a respective nip N is formed that the resulting frictional engagement is sufficient to transfer the tensile force necessary for cutting the material web 8 into partial material webs 2. The material web 8 cut in the longitudinal direction is thus supplied to the device 1 "from above".

The partial material webs 2 are now wound up to partial web web rolls 4.

Partial material web rolls 4 of adjacent partial material webs 2 are arranged axially offset from one another in two winding position groups A, B at two different circumferential positions PA, PB. In each winding position group A, B, the individual partial material webs 2 have a certain axial distance from one another and they each have a winding axis 13, 14. The Teilmaterialbahnrollen 4 of the two winding position groups A, B are arranged to each other on the gap.

While the partial material webs 2, which are wound in the circumferential position PA, wrap around the central roller 5 by about 90 °, the partial material webs 2, which are wound in the circumferential position PB, are guided about the central roller 5 over about 270 °. The circumferential position PA is here referred to as the so-called "9:00 h position", the circumferential position PB, however, referred to as the so-called "3:00 h position".

The partial material web rolls 4 are mounted in their winding position groups A, B in winding stations 15, which each consist of two mutually parallel and preferably mirror-inverted winding jackets 16.1, 16.2. At each winding frame 16.1, 16.2 is a retractable into the winding tube 3, with a rotary drive 18 connected and radially movable to the central roller 5 guide head 17 is arranged.

The illustrated winding station 15 of the winding position group A shows the rotary drive 18 in two working positions: the Anwickelposition C and Endwickelposition D. However, the illustrated winding station 15 of the winding position group B is pivoted from a working position to an unloading position E. The pivoting takes place about a horizontally extending pivot axis 19th

There is now at least one sliding line 20 for the electrical supply of the rotary drive 18 of the guide head 17 and the rotary actuators 18 of the guide heads 17 are present.

The movement is shown for example at the winding position group A with a double arrow F. In this case, at least one sliding line 25 for the electrical supply of the device 24 for movement of the carriage 23 and the means 24 for moving the carriage 23 is present.

As already stated, at least one, preferably each winding station 15 is pivotable between a working and an unloading position E by means of a device 26 for pivoting about the horizontally extending pivot axis 19. In this case, at least one conductor line 27 for the electrical supply of the device 26 for pivoting the winding station 15 and the devices 26 for the rotation of the winding stations 15 is present.

Moreover, at least one conductor line 29 for transmitting signals from a not explicitly shown and preferably central control / regulating unit 28 to the rotary drive 18 of the guide head 17 or the rotary drives 18 of the guide heads 17, to the device 24 for movement of the carriage 23 and The devices 24 for moving the carriages 23 and / or the device 26 for rotating the winding station 15 or the devices 26 for rotating the winding stations 15 are provided. In this case, the at least one contact line 29 can run parallel to those for the other devices 18, 24, 26 in the same strip 21 or housing. The preferably central control unit 28 can be assigned in a known manner to a higher-level process control system.

In the in the FIG. 1 illustrated device 1 are the contact rails 20, 25, 27, 29 arranged only by way of example.

The device 1 is preceded by a longitudinal cutting device 6, in particular a roller cutting device, in the running direction L (arrow) of the partial material webs 2. It has a feed section 7 in which a usually machine-width material web 8, for example a paper or board web unwound from a jumbo or mother roll, is supplied. The material web 8 then passes through a cutting section 9, in which it is divided by known per se, such as cutting blades 10, 11, into a plurality of partial material webs 2. At least one, essentially transverse to the direction L (arrow) of the partial material webs 2 extending grinding line 36 for the electrical supply of the motors of the cutting blades 10, 11 may be present.

The cutting blades 10, 11 cut the subsequently guided over a further roller 12 web 8 in this case in the longitudinal direction. For this purpose, a certain tensile force is required, which is applied via the central roller 5. The partial material web rolls 4 formed on the winding cores 3 are pressed so strongly against the surface of the central roll 5 when a respective nip N is formed that the resulting frictional engagement is sufficient to transfer the tensile force necessary for cutting the material web 8 into partial material webs 2. The material web 8 cut in the longitudinal direction is thus supplied to the device 1 "from below".

Partial material web rolls 4 of adjacent partial material webs 2 are arranged axially offset from one another in two winding position groups A, B at two different circumferential positions PA, PB. In each winding position group A, B, the individual partial material webs 2 have a certain axial distance from each other, but otherwise may have the same or approximately the same winding axis 13, 14. The Teilmaterialbahnrollen 4 of the two winding position groups A, B are arranged to each other on the gap.

While the partial material webs 2, which are wound up in the circumferential position PA, wrap around the central roller 5 by about 90 °, the partial material webs 2, which are wound up in the circumferential position PB, are guided over the central roller 5 over approximately 180 °. The circumferential position PA is here referred to as the so-called "1:00 h position", the circumferential position PB, however, referred to as the so-called "11:00 h position".

The partial material web rolls 4 are mounted in their winding position groups A, B in winding stations 15, each of which is parallel to one another arranged and preferably mirror-image formed winding blocks 16.1, 16.2 exist.
