Method for drawing at least one material web into a processing device

The invention relates to a method for drawing at least one material web into a processing device according to the preamble of claim 1.

There are processing devices, such as rotary web presses known, the material webs, for example, process substrates, which are unwound from rolls of material, such as Bedruckstoffrollen. For this purpose, a leading end of the material web must first be pulled into the processing device. If necessary, retraction of the material web must take place independently of any preceding material web. For this purpose, there are Einziehhilfen, which may have, for example, Einziehketten along a guide system preferably motor driven pull the web and in particular its leading end along a transport path through the processing device. Usually, the leading end of the material web is connected to the pulling-in aid and then the pulling-in aid is moved along the transport path substantially along the transport path until the material web has been drawn into the processing device. The leading end of the material web can be connected, for example, at a leading end of a Einziehelements the Einziehhilfe and / or at a trailing end of the Einziehelements and / or between the leading and the trailing end of the Einziehelements with the Einziehelement.

The generic DE 101 18 870 A1 discloses a method for drawing at least one material web into a processing device, wherein at least one roll of material on which the at least one material web is at least partially wound, is rotatably mounted about an axis of rotation and wherein in a joining process the at least one Material web with at least one movable pulling-in element at least one pulling aid is connected.

DE 10 2008 000 242 B3 it is known in the context of a

Standstill roller change a material roll to be replaced against a unwinding until a material web to be replaced is sufficiently tightened to cut through this web, with a conditional by tightening a displacement of this web partially wrapped pendulum roller is detected.

DE 10 2006 037 189 A1 and DE 101 46 631 A1 each have a

Reel change method known, which is insofar suitable for drawing at least one material web in a processing device, as an existing material web a new, associated material web through the

Processing device pulls.

DE 10 2008 044 496 A1 discloses a method for drawing at least one material web into a processing device, wherein at least one

Roll of material on which the at least one material web is wound at least partially, is rotatably mounted about an axis of rotation, and wherein in a joining process the at least one material web is connected to at least one movable draw-in element of at least one pulling-in aid. After the material web has been drawn into the processing device, the at least one material roll is turned against one

Abspulrichtung turned about the axis of rotation until a web tension of the at least one material web reaches a first predetermined value.

The invention has for its object to provide a method for drawing at least one material web in a processing device.

The object is achieved by the features of claim 1. The achievable with the present invention consist in particular that

Damage to at least one material web and / or a coupling element and / or at least one pull-in element and / or connections between these can be avoided. This is preferably done by rotating at least one roll of material against a unwinding direction about a rotation axis after a joining operation until a web tension of the at least one material web reaches a first predetermined value, preferably nonzero. As a result, the web tension of the material web to be recovered can be constructed in a controlled manner. Thus, it is prevented that an unstressed material web is accelerated abruptly, which would be the case, for example, if not previously built-up tension, but a retraction would accelerate while the web is still sagging.

A further advantage is that, for setting a first predetermined value of the web tension, means can be used which can also be used in a running processing operation to control the web tension, for example at least one drive motor which drives the material roll and / or at least a sensor device, which is preferably designed as a roller and / or lever. As a result, no additional devices are necessary, but it is sufficient to instruct an operator accordingly or a machine control

to program accordingly. In particular, the preferred is also the

Machine control already programmed so that rotational movements of the at least one roll of material are used as a way to control the web tension. By contrast, the at least one pull-in element is preferably not usable in a processing operation, in particular a printing operation after a pulling-in process.

Another advantage is the far - reaching automation of the

Retracting process.

A further advantage of at least one embodiment in which a preferred Coupling element is used, is that tensile forces are distributed as evenly as possible on the material web, in particular with respect to their width.

Another advantage of at least one embodiment is that the arrangement of the at least one pull-in element in a start position for reproducible

Conditions and thus consistent quality of the Einziehvorgangs ensures.

Another advantage of at least one embodiment in which preferably the material roll is moved to a completed connection between the material web and retraction in a roll-off, is that the bonding of the material web is facilitated with the at least one retraction element for geometric reasons.

Another advantage of at least one embodiment in which preferably the at least one roll of material is again rotated during the alignment process and / or continues counter to the unwinding direction about the axis of rotation is that thereby a web tension can be maintained throughout.

A further advantage of at least one embodiment in which a path length covered by the at least one pull-in element is determined from signals of a rotary encoder is that different positions of the at least one

Retraction are selectively accessible without a large number of position sensors would be required. In particular, the at least one pulling-in element can thus also be arranged in the starting position.

Another advantage is that different long coupling elements for different types of material, such as paper types, can be used and that the process still does not need to be modified because

Accordingly, only a larger angle of rotation of the roll of material opposite to the unwinding is achieved before the web tension reaches the first predetermined value. An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

The at least one first drive motor is arranged pivotably together with the at least one common support 09 or support frame 09 and the respective support arm 08 about the pivot axis 07. This means that in the case of a pivoting movement of the at least one common carrier 09 or supporting frame 09, which is brought about, for example, by the pivoting drive, the at least one first drive motor is also pivoted. This leads to constant operating conditions for the at least one first drive motor.

For the sake of simplicity, it should be assumed that the trailing end 37 of the at least one coupling element 19 coincides with the leading end 31 of the material web 01, wherein a flat

Of course, preference is given to compound.

In a method for drawing the at least one material web 01 in the

Processing device, the at least one retraction element 17 is preferably initially in a supply 24 of at least one Einziehhilfe 16th

In a process referred to as the preparation process, the at least one pull-in element 17 is preferably moved into a position 29 configured as a ready position 29. It can be provided, for example, that the at least one

Einziehelement 17 in the supply 24 of the Einziehhilfe 16 already in the

Standby position 29 is located.

In a process referred to as a coupling process, the at least one coupling element 19 is preferably connected to the at least one material web 01. It is not relevant whether the preparation process takes place before the coupling process or vice versa. Depending on the dimensions of the at least one coupling element 19, the at least one

Coupling element 19 preferably by rotation of the at least one roll of material 04 against the unwinding device A at least partially on the at least one

Material roll 04 wound up.

In a connection process, preferably after the

Preparation process and the coupling process performed process, the at least one material web 01 is connected directly or preferably via the at least one coupling element 19 with the at least one retraction 17. Preferably, the at least one material web 01 is indirectly connected to the at least one retraction element 17 by the at least one connected to the at least one material web 01

Coupling element 19 is connected to the at least one retraction 17.

Preferably, the at least one material web 01 is positively connected to the at least one retraction element 17. More preferably, the at least one

Material web 01 indirectly positively connected to the at least one retraction element 17 by the at least one connected to the at least one material web 01 coupling element 19 is positively connected to the at least one retraction 17.

In a process referred to as a positioning process, the at least one pull-in element 17 is preferably moved into a position 28 designed as a start position 28. In the positioning process, the at least one roll of material 04 is preferably rotated in the unwinding direction A about the rotation axis 03, for example in order to facilitate and / or facilitate the movement of the at least one pull-in element 17. If necessary, the positioning process can be omitted, for example if it is advantageous for geometrical reasons, the standby position 29 at the same time as

Starting position 28 to use. The connection process is preferably carried out before

Positioning process, but can with appropriate geometry even after the

Positioning process done. If the connection process before the

Positioning process, it is preferred in the positioning process, the leading end 31 of the web 01 and / or the at least one coupling element 19th at least partially around the roller 13, for example measuring roller 13, preferably such that subsequently the at least one coupling element 19 and / or the at least one material web 01 touches the roller 13 at a wrap angle of at least 90 ° and more preferably at least 135 °.

In a process referred to as a tensioning process, preferably carried out after the joining process and the positioning process, the at least one

Material web 01 taut until a web tension is above a first predetermined, preferably non-zero value. Preferably, the material roll 04 is rotated by means of the at least one first drive motor counter to the unwinding A about the rotation axis 03, preferably until the web tension has reached the first predetermined value, preferably wherein the at least one retraction element 17 in the

Start position 28 remains. In particular, the at least one material web 01 to be pulled in is tensioned by rotation of the at least one material roll 04 counter to the unwinding direction A about the axis of rotation 03 to which the at least one material to be pulled in

Material web 01 is at least partially wound up. Alternatively or additionally, in principle, the at least one pull-in element 17 can also be moved along the at least one pull-in path in order to increase the web tension. The web tension is preferably measured by means of at least one sensor arrangement. Preferably, the at least one designed as a dancer lever 12 or pendulum lever 12 lever 12 is formed as part of such a sensor device and / or this lever 12 is monitored by a sensor device. A reference force, which is exerted on the lever 12, for example by a spring and / or a hydraulic piston and / or a pneumatic piston, presses the lever 12 in a basic position. The material web 01 wraps around the roller 13 arranged on the lever 12 such that an increase in the web tension of the material web 01 deflects the lever 12 counter to the reference force. The deflection of the lever 12 is thus a measure of the web tension of the at least one material web 01. Preferably, the at least one sensor arrangement also acts in one

Processing operation, such as a printing operation in which the at least one material web 01 is unwound at a process speed of the at least one roll of material 04, with the at least one first drive motor together to maintain a web tension at or above a certain value and / or within certain limits , The first predetermined value of the web tension is preferably the lowest value of the web tension that can be measured by the sensor device. More preferably, the first predetermined value of the web tension is that value of the web tension at which the lever 12 is moved out of the basic position. Preferably, the

Tensioning process initiated as soon as the at least one pull-in element 17 has arrived at the start position 28. Preferably, the reference force is adjustable, for example, to be able to set different web tension in the processing operation, which are preferably each controlled such that the lever 12 is held in a central position. Therefore, the respective reference force must be adjustable so that this center position corresponds in each case to the desired web tension. Preferably, the reference force during the voltage operation is set to correspond to a control of the web tension to 20 N to 40 N (twenty Newton to forty Newton). Preferably, the reference force during the voltage operation is set such that it is a regulation of the web tension to a lowest

adjustable value corresponds. This leads to a particularly gentle treatment of the material web 01 during a drawing-in process. At the end of the tensioning process, the rotation of the at least one roll of material 04 is preferably stopped. In particular, the drawing-in process takes place after the tensioning process.

In a process referred to as alignment process, the at least one roll of material 04 is preferably moved from a first position, which is preferably a Aufachslage, in a second position, which is preferably a roll-off. In this case, the web tension is preferably maintained above the first predetermined value and / or a second predetermined value and is preferably the at least one carrier 09 or support frame 09 by means the pivot drive is pivoted about the pivot axis 07 and is preferably the roll of material 04 by means of at least one first drive motor against the

Abspulrichtung A rotated about the rotation axis 03 and / or moves the at least one retraction element 17 along the at least one Einziehwegs. The alignment process preferably takes place after the tensioning process. Preferably, a regulation of the web tension takes place from the tensioning process by means of a same system, as well as during a processing operation, for example printing operation. It is conceivable to carry out the tensioning process after the alignment process and, accordingly, to increase the web tension to or above the first predetermined value only when the at least one roll of material 04 is in the second position, that is to say preferably

Rolling is located. A second predetermined value may for example be a tolerance value which is below the first predetermined value and takes into account fluctuations in the web tension during the drawing process.

In the later, for example, subsequent and preferably final, referred to as retraction process operation is preferably the at least one retraction 17 moves along the at least one Einziehwegs and at the same time rotated the at least one roll of material 04 in the unwinding A. As a result, the at least one is preferably connected to the at least one via the at least one coupling element 19

Einziehelement 17 connected material web 01 along their transport path fed into the processing device. During the drawing-in operation, it is preferable to have the same web tension control of the processing device active, which is also active during a processing operation of the material web 01 in the processing device. The arranged on the lever 12 roller 13 and the at least one, rotations of at least one roll of material 04 causing and / or feasible drive are preferably part of this web tension control. Preferably, however, during the processing operation, the web tension is set at a value between 80 N / m (eighty Newton per meter) and 150 N / m (one hundred fifty Newton per meter).

Preferably, the lever 12 is placed in the basic position, if after Alignment process takes a longer break before initiation of the collection process takes place. If required, the at least one roll of material 04 is preferably moved in the axial direction together with the at least one and preferably at least two support arms 08 in order to adjust and / or correct the position of the at least one roll of material 04 and / or the at least one material web 01 ,

The preparation process and / or the coupling process and / or the

Connection process and / or the positioning process and / or the

Tensioning process and / or the alignment process and / or the retraction process are manually executable, either alone by the work of an operator or by a respective activation of a corresponding device by the operator, preferably in example optical and / or acoustic control by the

Operator. Preferably, the coupling process and / or the connection process are carried out manually. Preference is given to the preparation process and / or the

Positioning process and / or the tensioning process and / or the alignment process and / or the retraction process executed machine controlled, more preferably, after an operator has given a corresponding command to a machine control and / or has left a security area of the Rollenabspulvorrichtung 02. Preferably, the positioning process and / or the tensioning process and / or the alignment process and / or the retraction process are such that after the web tension is above the first predetermined value at least until completion of the retraction process at any time the at least one roll of material 04 and at least one retractable element 19 stand still at the same time.
