Definitions
- the invention relates to a method and an apparatus for drawing in a material web according to the preamble of claims 1 and 17, respectively
- Devices of this type are used in printing presses in order to convey the beginning of the web of material along the desired drawing-in path through the printing press. This is necessary, for example, when moving in for a new production, or whenever a material web is torn off during the printing process, so that the beginning of the web of the new material web cannot be pulled through by means of a flying roll change.
- the printing units can be traversed along different conveying paths in modern printing presses in order to be able to achieve correspondingly different printing results, so that when converting, the new material web must be drawn in along the corresponding drawing-in path.
- a device for pulling a web into a treatment station in which the band-shaped pull-in means can be rewound from a winding roll at the inlet of the treatment station to a winding roll at the outlet of the treatment station.
- the two winding rolls each have a drive.
- DE 19724 123 A1 also shows, in one embodiment, a finite drawing-in means which can be rewound between two respectively driven bobbins.
- EP 04 18 903 A2 discloses a device for pulling in a material web, wherein a pulling-in means is driven by a motor, which is regulated as a function of measurement data determined during the pulling-in process. The regulation takes place with regard to a constant retraction speed or speed.
- DE 94 09 390 U1 discloses a device for pulling in a material web, a pulling means being driven by a stepper motor. A transport route already covered by the infeed means is detected by sensors.
- a finite drawing-in means being driven by means of a drive in the region of a delivery area for the web.
- this drive is regulated with respect to a speed - possibly correlated with an independently driven unit of the machine, and in a second variant with a torque.
- the invention has for its object to provide a method and an apparatus for pulling a web of material.
- An advantage of the invention is in particular that the machine can be started up quickly and safely after it has been drawn in. The feed takes place in spite of the possibility of high insertion speeds, at the same time very gentle on the material.
- the collection means can in principle be infinite, i. H. be designed as a closed band-shaped material which can be conveyed via a driven roller in the region of a beginning of the pull-in path and a roller in the region of an end of the pull-in path.
- the pull-in means is preferably finite, its ends are each arranged on a bobbin and can be rewound from a bobbin in the area of a start of the draw-in path to a bobbin in the area of the end of the draw-in path and vice versa. However, both ends always remain connected to the respective bobbin.
- the pull-in means is driven by driving one spool each in the area of the start and end of the pull-in.
- These drives can advantageously be driven in two directions of rotation for winding or unwinding the pull-in means.
- a controllable electric motor is used to drive the bobbin, at least at the end of the feed path, so that the bobbin can be driven in a controlled manner with different rotational speeds and / or torques.
- the drives of both coil formers are preferably designed to be controllable with respect to the speed and / or the applied torque.
- the feed can be determined by appropriate measurement of the feed speed of the feed means by means of measuring points or by detecting the unwound or wound angle on the bobbin, and a constant feed speed can be regulated on the feed means by regulating the electric motor.
- the applied torque e.g. electrical power
- the applied torque can be determined and a specific torque set or a maximum torque can be monitored.
- the respective electric motor is then controlled according to a speed (e.g. frequency) or a torque (power) depending on the requirement.
- One version is particularly advantageous, when the drive is operated in the area of the end of the draw-in path (e.g. in the superstructure area) with speed or speed control, while the drive in the area of the start of the draw-in path (e.g. in the Role changer area) with regard to a moment, e.g. B. a constant retention torque is operated.
- a uniform pull-in is made possible and a certain tension of the web is ensured during the pull-in process.
- This procedure (regulation with regard to the speed and the torque) prevents so-called sacks from being formed in the web path due to insufficient tension and / or the tensioning of a dancer roller arranged in the web path being too great.
- such a procedure and device are operatively connected to a machine control and / or a web tension control intended for operation. That is, it can already i. V. m. a basic setting for the aggregates influencing the web tension - e.g. B. dancer rollers - an operational machine can be created.
- the linearly directed feed path and, depending on the time, the linearly directed feed speed of the draw-in means can be determined in a simple manner and then regulated to a desired value by corresponding regulation of the speed of rotation of the bobbin.
- a corresponding dependency of the target speed on the number of revolutions that is stored in the software as a control curve is also conceivable.
- a printing machine 01 for treating a web or material web, for. B. for printing a paper web
- a device for pulling in is provided for pulling a start of the web into the machine 01, by means of which a start of the web can be conveyed from a start of the pull-in path to an end of the pull-in path. Possibly. a manual route through the machine can follow before or after this mechanical feed path.
- the printing press 01 which is only shown schematically in the drawing, has, for example, an assembly 02 designed as a printing unit 02, here with two double printing units or four printing units, and an assembly 03 and a folding former 04 designed as a roll changer 03.
- At the former 04 includes a Folder 05 designed unit 05 which further processes the web.
- the web (not shown) runs in front of the roll changer 03 through one or more printing units 02, possibly over a superstructure (not shown) with a slitter and reversing deck over the former 04 the material web provided.
- the device has in a front area of the machine in which a web to be drawn in can be connected to a pull-in means 06 - hereinafter referred to as the receiving area - and in a rear area in which the drawn-in web is released from the pull-in means 06 - in called the following delivery area - each a bobbin 07; 08 on which the pull-in means 06 can be wound up or unwound from it.
- the pull-in means 06 is endless, i. H. as a loop, which instead of on bobbins 07; 08 a transport roller or roller rotates in the receiving and delivery area.
- These transport rollers are preferably in the manner of the bobbins 07; 08 driven by speed or torque. In order to reduce slippage, they can cooperate, for example, with pressure rollers or rollers.
- the receiving area is preferably located in the vicinity of the roll changer 03, so that the web can be guided through the pull-in means 06 directly after unwinding from the roll.
- the delivery area can in principle be arranged at any point along the web path up to behind the former 04. In the advantageous embodiment shown here, the delivery area and thus the bobbin 07 is arranged after the (last) printing unit 02 that has been passed through, but before the former 04. If turning bars are arranged in the superstructure, the delivery area can possibly be located in front of these turning bars in the railway path, if the guide for the pull-in means 06 and the track is not designed to bypass the turning bars.
- the entire web is drawn in straight up to in front of the former 04 and only when this web has been drawn in is the knife placed in the superstructure and the new sub-web is drawn in via the turning bar.
- the delivery area is located just before the funnel inlet.
- the bobbin 07 is in the delivery area by means of a motor 11 drive, z. B. an electric motor 11, in particular by means of an at least with respect to its speed controllable AC motor 11, driven.
- a simpler, preferred embodiment only one control is carried out by ⁇ to the desired value for the frequency of the motor 11 without feedback in a
- Control loop is only impressed.
- the motor 11 is controlled by a setpoint value h ⁇ u for the speed or frequency, ie ultimately under, based on a setpoint specification of an inner control loop of the drive
- the winding or unwinding speed of the pull-in center 06 is specified.
- an actual value of a measured angular velocity or the number of revolutions per unit of time of component or motor is fed back to a drive controller (not shown).
- the desired value h des which ultimately represents the retraction speed , for the speed or frequency is predefined for the motor 11 or its drive control by a control device 12.
- This control device 12 has, for example, a frequency converter 13 and a control and / or computing unit 14, in particular a servo control unit 14, for. B. executed as a servo PLC 14.
- the setpoint frequency is now determined in a logic (or an additional logic component) integrated in the servo PLC 14 and is made available for the motor 11 by the frequency converter 13.
- the retraction speed v so n can be specified directly and manually, for example via an input medium or a corresponding interface of the control device 12, the control device 12.
- the retraction speed v so // is specified via a higher-level control device 16, e.g. B. a machine controller 16. This ensures the synchronization between the speed of movement of the feed means 06 and at least components or units 02; 03; 05 of the printing press 01, which interact with the web to be drawn in, for example physical contact.
- a rotary drive 17 of the printing unit 02 and / or a rotary drive 18 of the roll changer 03 and / or a rotary drive 20 of the folder 05 is in signal connection with the machine controller 16.
- the rotary drives 17; 18; 20 are preferably mechanically independent of one another, but are electronically connected to one another via the machine control 16.
- a certain machine speed e.g. B. a certain retraction speed in the retraction operation
- the movement control of the subordinate drives 17; 18; 20 preferably follows a leading value of a so-called electronic leading axis ⁇ .
- the position of the leading axis ⁇ can either be on one of the units 02; 03; 05, e.g. B. orient the folder 05, the printing press 01 and the other units 02; 03 supply the specifications from this, or the leading axis ⁇ runs - if necessary after calibration on one of the units 02; 03; 05, for example the folder 05 - freely around and delivers further Operation of the positions on all aggregates 02; 03; 05.
- An angular velocity of this revolving leading axis ⁇ then corresponds to a predetermined machine speed, for example a "retraction speed for the automatic retraction” or a “printing” with a specifiable speed or a product output.
- a predetermined machine speed for example a "retraction speed for the automatic retraction” or a "printing” with a specifiable speed or a product output.
- this can be done continuously by arranging at least one sensor on the coil former 07; 08 can be determined, but it is preferably determined from the basic diameter of one or both bobbins d07; d08, the number of winding layers or revolutions u 0 ⁇ on one or both bobbins d07; d08 and the thickness d06 of the feed center 06 determined. If a slight advance in the speed n v is to be provided in view of a voltage to be maintained in the pull-in means 06, this must also be taken into account additively.
- ⁇ to a current setpoint value for a rotational speed ergilbt in principle for example by the connection to n + ⁇ , ⁇ * (d0X + (2 * d06 * u 0X))
- the resolver 19 is shown in solid lines in the area of the coil body 07, and in dashed lines in the area of the coil body 08.
- a corresponding signal for the motor 11 is then processed in the control and / or arithmetic unit 14 and the frequency converter 13 in order to keep the pull-in speed constant and is fed to it.
- the motor 11 in the delivery area is thus operated in a speed-controlled manner with a view to a constant drawing-in speed v during the drawing-in operation.
- the expression dOX + (2 * d06 * w ox ) then represents a current, calculated diameter DOX (D07, D08) after u 0x revolutions.
- a motor 21 driving the bobbin 08 in the receiving area e.g. B. electric motor 21, in particular an asynchronous motor 21, on the other hand, is operated at least in torque-limited mode. This is done via the servo control of the control and / or computing unit 14.
- Logic for determining a target frequency for the motor 11 and the servo control for the motor 21 can also be implemented in separate components.
- a desired belt tightening occurs when the motor 21 is pulled in, by actuating the motor 21 in the receiving area with a constant restraining torque, the motor 21 basically running in the opposite direction of rotation for unwinding.
- the pull-in mode the pull-in means 06 is thus pulled by the motor 11 and the bobbin 07 in a speed-controlled manner from the roll changer 03 to the delivery area (for example to the folder 04), the motor 11 being fed by the frequency converter 13 and this being fed by the control and / or arithmetic unit 14 a calculated target value h des for the frequency depending on the current
- Machine speed (or from the nominal value of the retraction speed 1 ,,,) and the calculated diameter D07; D08 of the bobbin 07; 08 receives.
- the motor 21 in the receiving area (eg near the reel changer 03) is controlled by the control and / or computing unit 14. In the pull-in mode, for example, he receives a low offset speed in the opposite direction to the unwinding. For example, by setting a train setpoint Z S0
- the motor 21 is "pulled through” by the more powerful, speed-controlled motor 11 and thus builds up the desired strip tension.
- the motor 11 receives its frequency setpoint, ie the setpoint ⁇ so! L , according to the currently calculated
- the motor 21 receives an adjustable speed evaluated with a fixed diameter, for. B. of 220 mm for the empty drum.
- an offset speed is preferably added, as in the pulling-in process, in order to ensure a constant advance relative to the motor 11 or its coil former 07. Due to the constant advance of the bobbin 08 and an adjustable tension setpoint Z so n ⁇ r for rewinding, the desired tape tension is built up in rewinding mode .
