Method for controlling a rotational speed and / or a rotational angle position of at least one position-controlled drive motor of at least one device of a folding apparatus

The invention relates to a method for controlling a rotational speed and / or an angular position of at least one position-controlled drive motor of at least one device of a folding apparatus according to the features of claim 1.

In folders, for example, folders of rotary rotary printing machines, paddle wheels are used in which signatures or folded products,

For example, individual sheets are stored in respective pockets formed by blades and then be designed out of these in the form of a scale flow on a conveyor belt. It is important for a smooth folding operation, especially at high production speeds, that the signatures in one

desired relative position and arrive at a desired time on the paddle wheel, for example, to prevent signatures between two

Paddles or between a paddle wheel and another component of the folder, such as a ribbon are clamped or damaged, for example, by large acceleration forces or forces that occur when a triggering of the signatures in the pockets, because the signatures at unfavorable times and thus in unfavorable positions in dip the bags.

GB 2 168 687 A discloses a method of feeding sheets to a sheet

Paddle wheel, wherein the sheets are transported along a transport path, and wherein at a certain position of the transport path, a sensor registers an arrival time of a respective sheet and wherein a transport speed of the sheet is registered and wherein a rotational speed of the paddle wheel accordingly the measured time of arrival and transport speed is regulated. The arrival time is measured at a position and starting from a constant

Transport speed optionally made an adjustment of the rotational speed of the blade wheel.

By DE 196 39 138 A1 is in process for supplying sheet to a

Paddle wheel is known, wherein based on a, generated by a arranged at a certain point first sensor, arrival signal and a web speed of a printing press by means of a processor, a first time is calculated at which a respective signature a target position in a product receiving area of the

Paddle wheel achieved and wherein based on a signal generated by a second sensor, the passing of a position by an airfoil and thus a

Phase angle of the airfoil indicates a phase difference between a current and a desired airfoil phase angle is calculated and wherein by repeatedly changing a rotational speed of the impeller this

Phase difference is compensated. It is thus calculated from a known distance and the web speed, a time or a time.

JP 7 267 457 A discloses a device with at least one paddle wheel into which individual sheets are introduced, wherein a respective position of the sheets is followed by means of a plurality of sensors detecting the sheet and thereby necessary changes of a rotational speed of the paddle wheel are carried out can, that as low as possible torques must be exerted by a drive motor on the paddle wheel.

From DE 195 09 947 A1 a folder with multiple drive motors for functional units of individual devices is known, all drive motors are connected via a machine inen control and synchronized. DE 10 2008 017 532 A1 discloses a method for controlling a rotational speed of a drive motor of at least one first apparatus of a folding apparatus, wherein a position of a first sensor is determined by means of a first sensor

Part track is detected at a first detection position and wherein a position of a plurality of further sub-webs is detected at a second detection position by means of a second sensor. In each case, a signal from the first and the second sensor is sent to a machine control associated with the folder. The machine control regulates on the basis of the signal of the first sensor and signals of other sensors, a supply of the further partial webs to the part of the path detected by the first sensor. The machine control further regulates the rotational speed of the drive motor of the first device on the basis of the signal of the second sensor and at least one further signal.

From DE 10 2005 009 132 A1 a method is known in which fold marks of already folded signatures are measured and based on the measurement results

Devices are responsible for attaching the folds, so that subsequent signatures are affected. Accordingly, the sensor and in particular its detection position must be arranged according to the corresponding device.

WO 2007/042391 A1 discloses a method in which a signature is detected by a sensor and slides on a folding table and is braked by friction and in which a folding blade of a longitudinal folding device subsequently encounters the signature between two folding rollers, wherein a phase position between an arrival of the sliding signature and an activation of the folding blade is regulated.

The invention is based on the object, a method for controlling a

Rotation speed and / or an angular position of at least one position-controlled drive motor to provide at least one device of a folder. The object is achieved by the features of claim 1.

A method for controlling a rotational speed and / or a

The angular position of at least one first position-controlled drive motor of at least one first device of a folding apparatus comprises at least one method step in which by means of at least one sensor a position of at least one signature on one

Detection position is detected, wherein a first signal from this at least one sensor is sent to a folding machine associated with the machine control and wherein at least one, the at least one signature between the detection position and the at least one first device, ie in particular from the detection position to the first device , Transporting second device is driven by at least one second position-controlled drive motor and wherein the at least one first and the at least one second position-controlled drive motor with the

Wherein a rotational position of the at least one first drive motor characterizing position signals and a rotational angular position of the at least one second drive motor characterizing position signals are each sent to the machine control, wherein at least one of these position signals represents at least a second signal having a rotational angular position of the at least one first device characterized and wherein the machine control on the basis of the first signal and the at least one second signal, the rotational speed and / or the rotational angular position of the at least one first drive motor of the at least one first device controls. Preferably, the at least one first device is a paddle wheel of the folder. Preferably, the at least one second device is a conveyor belt of the folder. Preferably, the sensor is arranged such that a signature is at the detection position while in contact with a conveyor belt of the folder.

It is preferred by means of the machine control on the basis of the first signal and the At least one second signal calculates at least one deviation signal and more preferably at least one correction signal is determined by including the at least one deviation signal, wherein the machine controller regulates the rotational speed and / or the rotational angular position of the at least one first drive motor of the at least one first device on the basis of this at least one correction signal , As a result, particularly simple control is realized.

Preferably, at least one of the at least one signature associated value in one, a plurality, preferably a fixed plurality of rewritable

Storage locations having stored memory. As a result, a regulation with respect to a plurality of signatures is realized with a large distance between the sensor and the first device. In this case, the machine controller regulates the rotational speed and / or the rotational speed due to the first signal and the at least one second signal

The angular position of the at least one first drive motor of the at least one first device after the at least one sensor has detected a position of at least one of the at least one signature subsequent signature. This at least one value is preferably identical to the first signal and / or the at least one second signal and / or the at least one deviation signal and / or the at least one correction signal and / or is preferably based on the first signal and / or the at least one second signal and / or the at least one deviation signal and / or the at least one correction signal. Preferably, at least one value associated with one of the at least one signature preceding the signature is deleted from the memory before or during the value assigned to the at least one signature in the memory, so that a finite, preferably one or two-digit number of memory locations is sufficient.

The achievable with the present invention consist in particular that the

Signatures and / or the positions of the signatures by means of the at least one and preferably exactly one sensor must be detected only once and that thereafter a Control of drive motors without additional sensors, but only on the basis of the machine control already existing data can be made. This is preferably done by assigning a position of the signatures with respect to the signatures of transporting devices incremental values and / or angular positions of an electronic Antriebsleitachse and predicted by this assignment, a relative position of the signatures in the course of another transport path and can be followed without further sensors, especially since drive motors are responsible for a further course of the transport path devices, such as conveyor belts or paddle wheels are also linked to the Antriebsleitachse.

Another advantage is that only one sensor is required for detecting the signatures, which can be arranged along the transport path at a detection position that is far away from a target position. Nevertheless, by a single capture of a signature at this specified location one

Machine control informed at any later time, at which point the signature is currently, regardless of a course of a

Transport speed of the signature after detection by the sensor. Such a machine controller may be a higher level machine controller responsible for controlling the entire folder or even larger units, but it may also be a machine controller that is only responsible for a relatively small area and, for example, relatively short signal paths and processing times allows, for example, a programmable drive control or a component of such, for example in the form of a plug-in card.

Another advantage is that even with changes of

Transport speeds of signatures and of these signatures transporting devices optimal alignment of signatures and components of others

Devices can be ensured, for example, from a pocket

Paddle wheel and / or grippers of a transport cylinder and / or jaws of a Jaw cylinder, and thus that, for example, when increasing or decreasing a production speed, for example, at the beginning or end of a production period, an optimal deposition of the signatures in the pockets of

Paddle wheel and / or action of a folding blade a Längsfalzeinrichtung and / or gripping the signatures by the grippers and / or jaws is possible.

Another advantage is that thereby the sensor for detecting the signatures at any distance to, for example, the paddle wheel or the

Transport cylinder or the jaw cylinder can be arranged and thereby, for example, even in constellations with limited space in the vicinity of at least a first device, such as the paddle wheel, an effective use of the sensor is possible and a structural design of the folder is thereby subject to less restrictions.

Another advantage is that run-up curves during commissioning of

Folders and optionally cooperating with printing presses do not always have to be redetermined, but that each folder provides itself at any time for an optimal setting by the device relative to the

Antriebsleitachse is adjusted in its angle, ie in its phase position, in dependence on a position of a signature relative to the drive leading.

A further advantage of an embodiment in which the memory is preferably designed as a ring memory or shift register and deviation signals of several signatures are stored successively in different memory locations of the memory is that the sensor can be arranged at a distance from the at least one first device , which is larger than a series of multiple signatures along their transport path through the folder, because multiple signatures can be tracked simultaneously. Data that is no longer needed is simply overwritten. A trained as a ring memory memory is a memory with a preferably fixed plurality of rewritable memory locations whose memory locations are filled in sequence with incoming data to be stored. In the process, the storage space is always filled with newly arriving data, which currently contains the oldest data. This ensures that all data has to be saved only once and deleted only once. On as a shift register

trained memory is a memory having a preferably fixed plurality of rewritable memory locations, in which incoming data to be stored are always stored in a same first memory location. Previously, data stored in this memory location will be copied to a previous memory location. Data that previously contained this next memory space is again allocated to a next but one memory location, etc. Data of a last memory location, which is necessarily the oldest data stored in this shift register, is deleted. For example, a number of memory locations may be adapted to the distance of the sensor from the at least one first device. A ring buffer is particularly fast with new data writable.

A further advantage of an embodiment in which at least one mean value is preferably formed from a plurality of values stored simultaneously in the memory, for example deviation signals, and from which at least one mean value the at least one correction signal is determined, is that for relatively slowly responding values

In any case, devices can not and must not react to every single signature and that it is thus possible to respond particularly effectively to long-term tendencies in position deviations of the signatures of ideal situations.

Another advantage of an embodiment in which preferably the at least one

Correction signal is determined from each exactly one stored in the memory deviation signal, said deviation signal other than a last in the

Memory stored deviation signal, is that despite a

intermediate capture of other signatures optimally on a location of each individual Signature can be responded.

A further advantage of an embodiment in which, after a determination of the at least one correction signal, on the basis of which the machine controller controls the rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device, the position of precisely one signature is preferably detected At least one further such correction signal is determined, is that layers of all signatures are taken into account and a maximum amount of information is processed through misplaced.

A further advantage of an embodiment in which, after a determination of the at least one correction signal, on the basis of which the machine controller controls the rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device, the positions of at least two signatures are detected before at least another such

Correction signal is determined, is that when averaged over several signatures adjustment of rotational angle positions and / or rotational speeds not unnecessarily much information is detected and / or processed.

A further advantage of an embodiment in which the machine control is preferably informed of each of the at least one signature at any time after detection of the position of this signature by the at least one sensor via a first number of angular units that the at least one first drive motor of the at least one must cover the first device until the at least one first device has reached a required rotational angle position and / or in the preferred

Machine controller with respect to each of the at least one signature at any time after a detection of the position of this signature by the at least one sensor is informed about a second number of angular units, the at least one second drive motor of the at least one second device must cover until this Signature has reached a target position, is that without further sensors optimized control of corresponding drives can be established.

A further advantage of an embodiment in which the machine control preferably carries out a comparison of the first number of angular units with the second number of angular units at least one checking time after the position of the respective at least one signature by the at least one sensor is detected, and preferably in the case of this the comparison, the first number of angular units is modified with a first gear ratio and / or modified before the comparison, the second number of angular units with a second gear ratio, is that gear ratios are taken into account.

A further advantage of an embodiment in which the machine controller preferably controls the rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device such that no later than one of the two numbers of angular units becomes zero, the other of the two numbers of angular units is below a tolerance value, is that a predetermined tolerance range is always adhered to, because in advance

appropriate measures are taken.

A further advantage of an embodiment in which, with regard to this at least one correction signal, a reference variable is the first number or the modified first number or the second number or the modified second number of angular units still to be returned, and a disturbance variable is an individual difference for each signature from the first or modified first number of angular units on the one hand and second or modified second number of angular units on the other hand, and a manipulated variable is a ratio of rotational speeds and / or

Drehwinkellagen at least the at least one first drive motor of the first device and the at least one second drive motor of the at least one second, the respective signature is still transporting device from the time of checking, is that depending on the design of the folding apparatus, the at least one first and / or the at least one second drive motor for optimizing the transport of the signatures can be controlled.

A further advantage of an embodiment in which, in the case of equality or deviation of the first or modified first number of angular units on the one hand, and the second or modified second number of angular units on the other hand, all are at the transport of the respective signature between a current position at the time of checking The second device involved in the respective signature and the target position are driven synchronously with the at least one first device, independently of an absolute transport speed of the respective signature, is that thereby a once achieved goal is secured and unnecessary computational effort can be saved.

A further advantage of an embodiment in which preferably the at least one first device and / or the at least one second device is a transport cylinder and / or a folding blade cylinder and / or a jaw cylinder and / or a

Belt guide system and / or a conveyor belt and / or a blade wheel and / or a folding blade of a Längsfalzeinrichtung, is that depending on the arrangement of the sensor and request to the folder always optimum transport of the signatures can be ensured. In particular, in the case where the at least one first device is a paddle wheel, there is the advantage that the paddle wheels arranged over the circumference of the paddle wheel at discrete angular positions are optimally controlled. Devices with such excellent angular positions require a particularly precise control, since they are less flexible with respect to a supply of signatures, as devices without excellent angular positions, such as conveyor belts. A further advantage of an embodiment in which, after a detection of the position of a respective at least one signature by the at least one sensor, information about a remaining number of path units to be backed by this respective signature still up to a checking position and / or a residual number of angular units, the devices still have to cover, which transport these respective signature along their remaining transport path to a destination position, are stored in a ring buffer and / or in a shift register, is that thus layers several signatures can be tracked simultaneously and that corresponding memory locations again for subsequent Signatures are available as soon as the corresponding previous signatures have passed the at least one first device.

A further advantage of an embodiment in which in each case this residual number is preferably checked in a first check and upon reaching a predetermined value

Minimum value of this remaining number is sent a third signal to the machine control, which determines the check time or from which the check time is calculated, is that a correction signal is calculated only when it is relevant and needed and that a corresponding sensor still in larger Distance from the first device may be arranged.

Another advantage of an embodiment in which preferably both the

Rotation speed and / or the angular position of the at least one first position-controlled drive motor of the at least one first device and a rotational speed and / or a rotational angular position of the at least one second position-controlled drive motor of the at least one second device is regulated, is that reacts particularly flexible to different situations can be, if not only one but several device with respect to a regulation of its rotational speed and / or rotational angle position are flexible. A further advantage of an embodiment in which the position of the at least one signature at the detection position is preferably detected by means of exactly one sensor is that costs for unnecessarily many sensors can be saved.

Another advantage of an embodiment in which preferably the

Rotation speed and / or angular position of precisely a first position-controlled drive motor of the at least one first or exactly a first device is controlled, is that less degrees of freedom in the control must be considered and the scheme is simply canceled.

Another advantage is that a particularly large number of devices can be regulated in this way with respect to their drive motor and thus

For example, devices can be controlled at any point along the transport path of the signatures or at several such locations. As a result, a particularly long way is possible along which is regulated and thereby a control with particularly low acceleration forces with respect to the signatures and / or devices involved is possible. In particular, this advantage occurs when multiple drive motors are controlled in this way.

An embodiment of the invention is illustrated in the drawings and will be described in more detail below.

Show it:

Fig. 1 is a schematic representation of an embodiment of a folding apparatus; Fig. 2 is a schematic representation of a detail of a folder; Fig. 3 is a schematic representation of a detail of a folder; Fig. 4 is a schematic representation of another embodiment of a

Folding apparatus.

A folding apparatus 01 of a printing machine, for example a web-fed rotary printing press, serves to print substrate 02, preferably web-shaped

Substrate 02 to process preferably folded signatures 22. The folder

01 can be arranged at least one former, with which the web-shaped

Substrate 02 before entering the folder 01 with at least one

Longitudinal fold is provided. In the folder 01 incoming sheet-shaped substrate

02 may be formed as a web or partial web or as a strand having a plurality of superimposed webs and / or partial webs.

In an exemplary embodiment, the folder 01 has a cross-cutting device 04, which intersects the incoming substrate 02 in signatures 22, also called sections 22. For this purpose, for example, equipped with knives 06 cutting cylinder 07 may be arranged. For example, corresponds to the cutting cylinder

07 an arrangement of the knives 06 on a circumference of the cutting cylinder 07 an array of sections 22 on a circumference of a forme cylinder

Press. With the cutting cylinder 07, a corresponding cylinder 08 cooperates, for example, as a transport cylinder 08 and / or folding blade

08 is formed. It can be arranged such a cutting cylinder 07, in which the knives 06 are rigidly arranged or flexibly adjustable. In a possible

Embodiment, a cutting cylinder 07 and a cooperating with this cylinder 08 are arranged so that they can be made to the substrate 02 and parked by the substrate 02 and that their rotational speed is variable, so that the knife 06 in contact with the substrate 02 is the same Have speed as the substrate to be cut 02, and so that, as long as the knives 06 are not in contact with the substrate 02, the cutting cylinder 07th and the cooperating cylinder 08 can rotate faster or slower to produce sections of different lengths (FIG. 1).

Under a signature 22 is understood below and in advance not only the folding apparatus 01 leaving finished product, but also each precursor of this product, which is located within the folder 01 and is no longer connected to a web 02. A signature 22 is thus in particular one of a material web 02 or printing material web 02 in a direction transverse to one

Transport direction of the web 02 separated portion 22 of the web. A signature 22 corresponds to an arcuate portion 22 of the material web.

In one embodiment of the folding apparatus 01, the cutting cylinder 07 is preceded, for example, by at least one draw roller pair 03 with respect to a transport path of the signatures 22, which regulates a tension of the printing material 02. In another or the same embodiment of the folder 01 is the cutting cylinder 07 with respect to the transport path of the signatures 22, for example, an acceleration section downstream. Such an acceleration section can, for example, ensure that a distance between successive signatures 22 arises. Such a distance serves on the one hand, that holding tools 09, in particular gripper 09 between the individual signatures 22 engage and hold them and on the other to the fact that distances between the front edges of the signatures 22 to a circumference of a transport cylinder 08, for example as a collecting cylinder 08th and / or folding blade 08 trained subsequent device 08 are adapted. The transport cylinder 08 preferably has further components 09, for example

Holding tools 09, in particular gripper 09 or puncture needles 09 and further preferably has activatable and deactivatable folding blade 1 1 on.

The transport cylinder 08 preferably has along its circumference a number of holding tools 09 and folding blades 1 1, which is designed so that the Transport cylinder 08 can be used either in multiple production and thereby passes each section of the substrate 02 immediately and optionally also in

Collective production can be used. It may also be arranged a second cutting cylinder 19, so that the sections of the printing material 02 can be cut once again transversely to adjust their length accordingly. It can also be arranged devices for gluing or stapling sections of the printing substrate 02.

The grippers 09 serve to hold the front edges of the signatures 22. The folding blades 11 are or are positioned in the middle of the respective section of the printing material 02. The folding blades 1 1 then work together in the usual way with formed as jaws 12 components 12 of a folding cylinder 13 or jaw cylinder 13 formed device 13, which continues the signatures 22. These are then optionally further processed, for example, longitudinally folded and fed by means of further devices 14, for example by means of at least one conveyor belt 14 and / or a belt control system 14, for example, at least one device 16 designed as a paddle wheel 16. The impeller 16 has a plurality of Schaufelradblättern 17, between which are formed as pockets 18 formed components 18 of the paddle wheel 16 (Fig. 2). Preferably, a paddle wheel 16 is the first

Device 16 is formed and at least one conveyor belt 14 is formed as at least one second device 14.

In one embodiment of the folding apparatus 01, at least one conveyor belt 14 is arranged relative to the transport path of the signatures 22 after the jaw cylinder 13 and at least one longitudinal folding device 24 is arranged with respect to the transport path of the signatures at or after this at least one conveyor belt 14. The at least one longitudinal folding device 24 has at least one as a

Longitudinal folding blade 23 trained device 23 on. With the at least one

Longitudinal folding device 24 can signatures 22 with Längsfalzen in a known manner be provided by the longitudinal folding blade 23 a signature 22 in a folding gap between two folding rollers 26 of the longitudinal folding device 24 abuts and the longitudinal folding rollers 26 from two sides against the signature 22 pressing this provided with a fold. The at least one longitudinal folding device 24 is preferably in turn downstream of at least one device 16 designed as a paddle wheel 16 in relation to the transport path.

At a point along the transport path of the signatures 22 by the folding apparatus 01, in particular in the region of a detection position, at least one sensor 21 and preferably exactly one sensor 21 is arranged. The at least one sensor 21 is arranged, for example, in the form of a photosensor 21. For example, the sensor 21 may register signatures 22 by receiving less light as soon as a leading edge of a signature 22 enters its sensor area and / or receives more light as soon as a trailing edge of the signature 22 leaves the sensor area. It can also record an image recording or a film recording of each signature 22, from which a position of the signatures 22 can be calculated. It is also possible, but in principle not necessary to arrange a plurality of sensors 21,

For example, to check a calculated position of a signature 22.

The at least one pair of draw rollers 03 or the acceleration section, the

Transport cylinder 08, the jaw cylinder 13 and the conveyor belt 14 and the belt guide system 14, the longitudinal folding blade 23 and in particular the paddle wheel 16 are devices 03; 08; 13; 14; 16; 23, which preferably in each case or at least partially combined in groups each have their own first or second drive motor. Such first and second drive motors are preferably position-controlled drive motors and more preferably position-controlled electric motors.

Such position-controlled drive motors are preferably connected to a superordinate machine control associated with the folding apparatus 01 and are connected to one another in particular via a common electronic drive-guiding axis. These electronic Antriebsleitachse provides a sequence of angular positions and is based on a sequence of clock pulses, preferably each clock pulse increases a value of the sequence of clock pulses. Preferably, the clock pulses follow each other in time equidistantly. Each clock pulse is assigned an angular position of the drive master. If successive clock pulses are assigned different angular positions of the drive master, one speaks of a rotation of the drive master. A greater deviation of the angular position of the drive guide between successive clock pulses corresponds to a higher rotational speed of the drive guide. The angular position of the drive master axis can also be called the incremental value. A change in the angular position can be expressed in certain angular units or increments. A rotational speed of the drive master axis corresponds to a number of angular units traveled and / or increments per clock pulse and / or per unit of time. A full angle then corresponds to a fixed number of

Angular units or increments. After this fixed number of angular units, the drive guide has once rotated by a full angle, regardless of their rotational speed. It is not necessary that during any one revolution of the drive baffle any device 08; 13; 14; 16; 23 or any rotor of a drive motor also executes exactly one complete revolution, however, such a linkage is possible and advantageous. Also changes of rotational angle positions of the devices associated with the Antriebsleitachse devices 08; 13; 14; 16; 23 are expressed in angular units.

A first or second drive motor and / or generally a device 08; 13; 14; 16; 23, which rotates synchronously relative to the Antriebsleitachse, in each case after this above-mentioned, fixed number of angular units of the drive guide repeatedly on an identical, defined angular position. In other words, this means that the specific angular position of this first or second drive motor and / or device 08; 13; 14; 16; 23 is reached again after just this fixed number of angular units. This means that clock pulses characterized by this rotation angle position are equally aquidistant distributed in the sequence of clock pulses of Antriebsleitachse, as the characteristic for each a completed revolution of the drive axle angular positions of the drive. This is also independent of actual, absolute rotational speeds of the corresponding first or second drive motor of the first and / or second device 08; 13; 14; 16; 23 the case. Such an angular position of the Antriebsleitachse also corresponds to a numerical value, which marks a certain point in the progress of an driven by the Antriebsleitachse process, for example, a transport path of a signature 22 and a whole folding operation of a larger number of signatures 22nd

A first or second drive motor or a first or second device 08; 13; 14; 16; 23, which rotates faster than the Antriebsleitachse, has, starting from a defined angular position, this defined rotational angular position again after a number of angular units of the Antriebsleitachse, which is less than a number of

Angular units required or intended for a complete revolution by the drive master. A first or second drive motor or a first or second device 08; 13; 14; 16; 23, which rotates more slowly than the driving guide axis, starting from a defined angular position, this defined rotational position again after a number of angular units of the Antriebsleitachse, which is greater than a number of angular units that the Antriebsleitachse required for a full turn or the is provided for this purpose.

Each first and / or second drive motor preferably has in each case a multi-turn encoder, which emits in each case position signals to the machine control. These position signals characterize respective rotational angle positions of the corresponding first and / or second drive motor. Various devices 08; 13; 14; 16; 23 have due to possible different gear ratios corresponding gear at the same rotational speeds of their first and / or second drive motors

may have different speeds at which signatures 22 of the respective devices 08; 13; 14; 16; 23 are transported along their transport path, so different transport speeds. Preferably, the position signals from the first and / or second drive motors to the

Machine control are sent and / or the rotational angle positions, which are given to the first and / or second drive motors by the machine control, with respect to the transport path of the signatures 22 converted and / or normalized, ie modified by means of a respective respective translation factor. This means that each angular unit of the Antriebsleitachse and preferably a certain difference of the angular position of the devices 08; 13; 14; 16; 23 corresponds to a defined and always the same distance, ie a normalized path unit along the transport path of the signatures 22. This means that, on the one hand, there are the angular units of the drive guide axis and, on the other hand, there are normalized path units which divide distances along the transport path. The normalized path units are due to the above-described translation and circumferential ratios fixed differences in the rotational angle positions of the respective drive motors and / or devices 08; 13; 14; 16; 23 assigned. This means that there is a fixed relationship between path units on the one hand and angular units of the respective drive motors and / or devices 08; 13; 14; 16; 23 on the other hand. In known gear ratios of gears, the first and / or second drive motors with the corresponding first and / or second devices 08; 13; 14; 16; 23, the position signals of the first and / or second drive motors represent second signals, the respective rotational angle positions of the at least one first and / or the at least one second device 08; 13; 14; 16; 23 characterize.

As long as no device 08; 13; 14; 16; 23 adjusted with respect to the drive, for example, accelerated, there is a fixed ratio of normalized

Path units along the path from the respective device 08; 13; 14; 16; 23 certain transport path on the one hand and angular units of the Antriebsleitachse other hand.

An angular unit of the drive-control axis preferably corresponds exactly to a normalized one Path unit along this transport route. This case will be discussed below and in the

Described above. It should be noted, however, that any other such relationship is possible and may be taken into account by simple multiplication. Acceleration of a drive and / or device 08; 13; 14; 16; 23 produces another such relationship. Either the position signals of the first and / or second drive motors are already normalized when they are connected to the

Machine control are sent or they are normalized by the machine control, so that normalized angular units of the drive leading can be obtained from position signals of all first and second drive motors. In this way, the machine control is informed at any time about how far a transport path through the respective devices 08; 13; 14; 16; 23 has progressed overall and thereby also how far a transport path through the respective devices 08; 13; 14; 16; 23 has progressed in comparison with each other.

In the case of the transport cylinder 08, such a normalized path unit or such an angular unit of the drive guide axis corresponds for example to a section of a

Circular arc of a circumference of the transport cylinder 08. This section of the circular arc can be converted over a radius to an angle of the transport cylinder 08, so that the position-controlled first or second drive motor can send an angle-dependent position signal to the machine control, by the machine control by means of corresponding known gear ratios in a distance or preferably converted into an angular difference of the drive master. In the case of a conveyor belt 14, such a normalized path unit or such an angular difference of the drive guide axis corresponds to a distance along a transport direction of the conveyor belt 14 and can likewise be adjusted to an angular difference of the conveyor belt 14

convert driving first or second drive motor, so that also from this first or second drive motor, an angle-dependent position signal can be sent to the machine control, which converted by the machine control in a path or preferably in an angular difference of the drive becomes. The angular units of the Antriebsleitachse therefore do not necessarily refer to temporally equal distances, but always on spatially equal distances, ie normalized path units based on the transport path of the signatures 22. Only at constant transport speed of the signatures 22 means the same time intervals.

If a signature 22 is detected by the at least one sensor 21, then a first signal is sent to the machine control. Here, for example, the

Sheet leading edge of this signature 22 a rotational angle position of the signature 22 just transporting device 08; 13; 14; 16; 23 and / or associated with the second drive motor. This angular position is also assigned to an angular position of the drive master. The machine controller is informed with respect to each of the at least one signature 22 at any time after the detection of the position of this signature 22 by the at least one sensor 21 via a first number of angular units which the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 has to travel until the at least one first device 08; 13; 14; 16; 23 has reached a required rotational angle position.

The machine controller is informed of how far a transport path s of the signature 22 from the spatial position or detection position at which the signature 22 is detected by the sensor 21 to a target position. Such a target position can be arranged, for example, in a pocket 18 of the paddle wheel 16 or on a position suitable for gripping by a gripper 09 or a folding flap 12 or on a folding table of a longitudinal folding device 24 (FIG. 3). The machine control system has this information as the path length or number of normalized path units and / or as the angular difference of the drive guide axis and in particular as the second number of angle units. The machine control has in particular of the

Acquisition time to information about how far a remaining transport path of the signature 22, for example, in normalized path units, at any time to a target position, ie in particular, which angle differences of the transport participating devices 08; 13; 14; 16; 23 are necessary until the signature 22 has been transported from a current position to the destination position. In other words, this means that the machine control is informed with respect to each of the at least one signature 22 at any time after the detection of the position of this signature 22 by the at least one sensor 21 on the second number of angular units, the at least one second drive motor of the at least one second device 08; 13; 14; 16; 23 until this signature 22 has reached the target position. Such information is thus information that represents a length of a remaining transport path of this signature 22 to a destination position or from which this situation can be derived clearly

In this way, the machine controller can compare at each time point how large a first number of normalized path units still to be traversed by the signature 22 from this time to the target position and how large a second number of angular units of the Antriebsleitachse is one of the target position

corresponding device 08; 13; 14; 16; 23 from this time still up to a required angular position of this device 08; 13; 14; 16; 23 angle difference to be covered, so that this device 08; 13; 14; 16; 23 is located at the arrival of the signature 22 at the target position in the required rotational angle position. A time at which such a comparison takes place is called the time of verification. Thus, the machine controller undertakes a comparison of the first number of angular units with the second number of angular units at least one checking time after the detection of the position of the respective at least one signature 22 by the at least one sensor 21. Depending on the gear ratios of existing gears, the first number of angular units is modified with a first gear factor before comparison and / or the second number of angular units is modified with a second gear ratio before the comparison. Based on this comparison, the machine control determines at least one

Deviation signal. The deviation signal is in particular a measure of how strong at a respective signature 22 deviates the first or modified first number of angular units from the second or modified second number of angular units.

A return of angular units of the drive guide is an addition of angular units to a hitherto current angular position of the drive guide. As described above, this is linked to the addition of clock pulses to the sequence of clock pulses via the rotation speed. Relative to devices 08 involved in the transport of signatures 22; 13; 14; 16; 23 is a return of normalized

Path units and of angular units of the drive guide a movement,

for example, rotation of the corresponding device 08; 13; 14; 16; 23, which causes a movement of signatures 22 along a transport path to just such normalized path units. A normalized path unit preferably corresponds to a section of the transport path which is smaller than 1 mm.

On the basis of the at least one deviation signal and preferably by means of a

Calculation, in which the at least one deviation signal is included, at least one correction signal is determined. This correction signal influences the regulation of the rotational speed and / or the angular position of the at least one first position-controlled drive motor.

If the deviation of the first or the modified first number of angular units on the one hand and the second or the modified second number of angular units on the other hand is equal or less than a tolerance value, the deviation

Machine control preferably ensures that all involved in the transport of the respective signature 22 between a current at the time of checking the position of the respective signature 22 and the target position involved second devices 08; 13; 14; 16; 23 independent of an absolute transport speed of the respective signature 22 in synchronism with the at least one first device 08; 13; 14; 16; 23 are driven, and preferably that all devices 08; 13; 14; 16; 23, the signature 22 from this Checking time still be transported on the way to the target position, run synchronously with the drive master and / or rotate.

If this first or modified first number of angular units on the one hand and this second or modified second number of angular units on the other hand differ by at least the tolerance value, then a rotational speed and / or in particular a rotational angle position of at least one device 08; 13; 14; 16; 23, which will still transport the signature 22 on the way to the target position from this checking time and / or which corresponds to the target position and / or regulates its first and / or second drive motor. From a regulation of the angular position, it is also preferable to regulate the rotational speed of the corresponding drive motor and thus also the corresponding device 08; 13; 14; 16. Preferably, therefore, in each case the rotational angle position of the at least one first drive motor is regulated. In particular, a ratio of unit units traveled per unit time of this at least one device 08; 13; 14; 16; 23 and per unit time traveled angle units of the drive control changed.

In particular, this takes place independently of absolute rotational speeds, that is to say, for example, of unit units of angular distance traveled per unit of time

Antriebsleitachse.

This means that the machine controller controls the rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 and / or the at least one second drive motor of the at least one second device 08; 13; 14; 16; 23 so that at the latest as soon as one of the two numbers of angular units is zero, the other of the two numbers of angular units is below the tolerance value.

With regard to the determination of the at least one correction signal, a reference variable is the first number or the modified first number of still to be covered Angular units and a disturbance variable for each signature 22 individual difference of first or modified first number of angular units on the one hand and second or modified second number of angular units on the other hand is and is a manipulated variable a ratio of rotational speeds and / or rotational angular positions of at least the at least one first drive motor of the first Device 08; 13; 14; 16; 23 and the at least one second drive motor of the at least one second, the respective signature 22 from the time of checking still transporting device 08; 13; 14; 16; 23. It is also possible to use the second number or the modified second number of angular units still to be used as the reference variable.

The checking time at which this comparison of the first and second numbers is performed is in principle freely selectable between the detection of the signature 22 and the achievement of the target position. However, preference is given to such

Verification time of comparison made hired at the just one of the signature 22 directly preceding signature 22 has arrived at their destination. Thus, a period of possible influence becomes maximum. If the relevant signature 22 is the first and / or the signature 22 does not have a preceding signature 22 for other reasons, then the check time at which the comparison is made is preferably as soon as possible after the signature 22 has been acquired by the at least one sensor 21. In this case, at least one signal, for example, the at least one correction signal is determined that then serves as a setpoint and to at least one corresponding

Control unit for the rotational speed and / or the rotational angular position of at least one first and / or second drive motor of at least one device 08 involved in the transport of the signature 22; 13; 14; 16; 23 serves.

Preferably, a first check and a second check are performed. After a detection of the position of a respective at least one signature 22 by the at least one sensor 21, the machine control system has information about a remaining number of signals remaining through this respective signature 22 up to a checking position distance units to be traveled and / or a remaining number of angular units, the devices 08; 13; 14; 16; 23 still have to cover that transport this respective signature 22 along its remaining transport path to a destination position. The machine control thus also has information on distance units of the recorded signatures 22 traveled since the detection by the sensor 21 of signatures 22 and on a distance between the detection position, ie the location of detection by the sensor 21 and a checking position, expressed in angular units of the drive control axis , The first check is that the

Machine control cyclically, preferably regularly, more preferably at intervals of less than 1 ms and even more preferably as often as possible by processing this information, preferably in particular by at least partially reading a designed as a ring memory or shift register memory checks whether a detected signature 22 at the Checking position has arrived, so that in each case this residual number is checked and upon reaching a predetermined minimum value of this residual number, a third signal is sent to the machine control, the

Check time or from which the checkpoint is calculated.

As soon as the machine control concludes that a signature 22 has arrived at the check position and / or at the check time, the second check takes place. The second check then consists in that, as described above, the first and second numbers of path units and / or angle units still to be traveled are compared and corresponding consequences are drawn. The second check thus always takes place when a signature 22 has arrived at the checking position, that is to say less frequently than the first

Checking and depending on the transport speeds, for example, in intervals of about 10 ms to 200 ms. In this case, so sets a specific result of the first

Check the above-described check time, to which the numbers of travel units and angular units are compared. The information about at what point in time and preferably at which angular position of the drive guiding axis a position of a signature 22 is detected by the at least one sensor 21 is preferably stored in the memory designed as a ring memory or a shift register which is read out for the first check. In any case, the memory designed as a ring memory or as a shift register has enough memory locations in order to be able to acquire information on all the signatures 22 located between the sensor 21 and the checking position. The ring buffer preferably has enough memory locations to be able to acquire information on all the signatures 22 located between the sensor 21 and the target position. In one embodiment as a ring memory, each newly acquired signature 22 becomes one

Overwriting memory space, which until then contains information about a signature 22 already removed from the area between sensor 21 and checking position. In another embodiment as a shift register, with each detection of a further signature 22, the information about previous signatures 22 is shifted by one memory location, in which case, for example, in each step

Information about an already out of the range between sensor 21 and

Verification position remote signature 22 omitted from the last memory space. Depending on the embodiment, all memory locations or only one or more relevant memory locations can then be read out in the first check, for example, each time.

In the following, a method is described in detail in which a signature 22 of a pocket 18 of a paddle wheel 16 is supplied, but the same can be analogous to a feed to the grippers 09 of the transport cylinder 08 or the jaws 12 of the jaw cylinder 13 or a longitudinal folding blade 23rd one

Longitudinal folding device 24 transmitted. The at least one first device 03; 12; 13; 16; 23 is thus formed in this case as a paddle wheel 16. In principle, as at least one first device and also as at least one second device a

Transport cylinder 08 and / or a folding blade 08 and / or a Falzklappenzylinder 13 and / or a belt guide system 14 and / or a conveyor belt 14 and / or a paddle wheel 16 and / or a folding blade 23 a Längsfalzeinrichtung 24 are used. Preferably, the at least one first device 08 acts; 13; 14; 16; 23 based on the transport path of the at least one signature 22 after a cutting cylinder 07 on the at least one signature 22, which has separated the at least one signature 22 of a web-shaped substrate 02.

At any time after detecting a location of a signature 22 by the sensor 21, the machine controller knows the exact location of the detected signature 22 and compares, for example, at the check time, whether a first number of normalized path units necessary to reach the signature 22 at the target position is, and a second number of angular units of the electronic Antriebsleitachse, the one of the paddle wheel 16 from this time to a required

Rotational angular position of this paddle wheel 16 to be traversed angle difference corresponds to a pocket 18 of the paddle wheel 16 is in a position such that

Signature 22 at just this target position can be optimally absorbed in this pocket 18 or will be recorded is equal to or how many normalized path units and / or angular units, these numbers differ. If these numbers are the same, the transport speeds of the signature 22 along the remaining

Transport path and the rotational speed and / or the rotational angular position of the paddle wheel 16 synchronously controlled. Ie. that preferably every one of the rest

Transport path of the signature 22 to the paddle wheel 16 involved device 08; 13; 14 travels an equal number of normalized path units per unit time as the paddle wheel 16. It is also possible to use a whole of the devices 08; 13; In each case, the transport speeds of the signature 22 along the rest of the transport path and the rotational speed and / or rotational position of the paddle wheel 16 are the same so regulated that the numbers become zero at the same time or within a tolerance range. This in turn is independent of actual transport speeds and rotational speeds. As described above, this is especially for accelerated processes, for example

Startup operations or stops relevant. The first number of travel units still to be covered by the signature 22 may, for example, correspond to a distance s14-18 of 300 mm. A distance that may correspond to a sum of the first distance s14-18 and a depth s18 of the pocket 18 may then correspond, for example, to 1300 mm.

The system is independent of rotational speeds of the position-controlled first and / or second drive motors. In particular, therefore, an optimal supply of the signatures 22 in pockets 18 of the paddle wheel 16 can be ensured, even if during transport speeds of the signatures 22 change, for example, at the beginning or end of a print job in the

Printing machine, where not only other transport speeds but also other distances between signatures 22 can occur due to different production speeds. Even with a machine stop, the assignments between leading edges of the signatures 22 and angular positions of the drive guide axis are retained as well as between the angular position of the pockets 18 and angular positions of the drive guide axis. As a result, an optimal supply of the signatures 22 to the pockets 18 of the paddle wheel 16 is ensured immediately upon restart of the printing machine and in particular of the folder 01 again.

Associations of all signatures 22, which are located behind the at least one sensor 21 with respect to their transport path and which are not yet in a pocket 18 of the

Paddle wheels 16 are or were arranged, and / or all involved in the remaining transport of said signatures 22 devices 08; 13; 14 to corresponding angular positions of the drive guide are preferably stored in the designed as a ring memory or shift register memory of the machine control. In particular, at least one deviation signal is calculated and stored in a memory having a preferably fixed plurality of rewritable memory locations, preferably a ring memory or shift register. In particular, be

Deviation signals of multiple signatures 22 are stored consecutively in different memory locations of the memory. The respectively oldest angular position and thus the respectively oldest deviation signal, which is located in this memory, is then associated, for example, with a signature 22 to be deposited as the next in a pocket 18 of the paddle wheel 16. Once control and regulation has been completed with respect to this signature 22, that is, once the signature 22 has been placed in a pocket 18, the corresponding information is deleted from the memory location and control and regulation of the next signature 22 is begun. This frees up a memory space, which is then assigned the next angular position of the drive master axis defined by a first signal of the sensor 21 generated by a signature 22. A memory to be read out is then selected, depending on the procedure.

The signatures 22 are supplied to the paddle wheel 16 at relatively regular spatial intervals, so that no large changes in the rotational speed of the paddle wheel 16 are to be expected. If strongly irregular spatial distances occur, then to avoid excessive acceleration forces with respect to the rotation of the paddle wheel 16 and an optimization of a course of the

Rotation speed or the angular position of the paddle wheel 16 are made by the associated angular positions not only of the next directly, but several next signatures 22 are taken into account in corresponding calculations, for example by forming an average value.

In this way it is possible, by means of at least one and preferably exactly one sensor 21 and connected via an electronic Antriebsleitachse first and / or second position-controlled drive motors and a corresponding machine control for an optimal supply of signatures 22 to all the sensor 21 with respect to the transport path downstream devices 08, 13, 14, 16 and components 09; 12; 18 to ensure. For example, you can also use an intermediary

Conveyor belt 14 whose transport speed is controlled and regulated as described above, signatures 22 are fed to a paddle wheel 16 having a constant rotational speed, this conveyor belt 14 ensures over its different transport speeds that the signatures 22 arrive at appropriate time intervals on the impeller 16 ,

In general, signatures 22 can thus be transported along a detection path through the at least one sensor 21 along their transport path and their position along the

Transport path with a rotational speed and / or rotational angular position of at least a first device 08; 13; 14; 16; 23 and / or at least one first drive motor and with a rotational speed and / or rotational angle position of at least one second device 08; 13; 14; 16; 23 and / or link at least a second drive motor, wherein the at least one first device 08; 13; 14; 16; 23 is associated with a target position of the signatures 22 and wherein the at least one second device 08; 13; 14; 16; 23 along a transport path from a detection position of the sensor 21 to the first device 08; 13; 14; 16; 23 is arranged.

Thus, a method for controlling a rotational speed and / or a rotational angle position of at least one first position-controlled drive motor of at least one first device 08 preferably results; 13; 14; 16; 23 of the folding apparatus 01, wherein by means of the at least one sensor 21, the position of at least one signature 22 at the

Detection position is detected and wherein the first signal from this at least one sensor 21 is sent to the folding machine 01 associated machine control and wherein at least one, the at least one signature 22 between the

Detection position and the at least one first device 08; 13; 14; 16; 23 and preferably from the detection position to the first device 08; 13; 14; 16; 23 transporting second device 08; 13; 14; 16; 23 is driven by means of at least one second position-controlled drive motor and wherein the at least one first and the at least one second position-controlled drive motor are connected to the machine control and wherein a rotational angular position of the at least one first

Drive motor characterizing position signals and an angular position of the at least one second drive motor characterizing position signals respectively to the

Machine control are sent, wherein at least one of these position signals represents at least the second signal having a rotational angular position of the at least one first device 08; 13; 14; 16; 23 characterized and wherein the machine controller based on the first signal and the at least one second signal the

Rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 regulates.

Preferably, the method is characterized in that by means of

Machine control on the basis of the first signal and the at least one second signal at least one deviation signal is calculated is further preferred that at least one correction signal is determined by including the at least one deviation signal, the machine control on the basis of this at least one

Correction signal, the rotational speed and / or the rotational angular position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 regulates.

Preferably, the method is characterized in that at least one of the at least one signature assigned value 22 is stored in a, preferably a fixed plurality of rewritable memory locations having memory and that of the at least one signature 22 associated value with the first signal and / or the at least one second signal and / or the at least one deviation signal and / or the at least one correction signal is identical and / or on the first Signal and / or the at least one second signal and / or the at least one deviation signal and / or the at least one correction signal based.

Preferably, the method is characterized in that the machine control on the basis of the first signal and the at least one second signal, the

Rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 controls after the at least one sensor 21 has detected a position of at least one of the at least one signature 22 subsequent signature 22.

Preferably, the method is characterized in that a plurality of respectively assigned to a different signature 22 temporally successively in

different preferably fixed plurality of memory locations of the memory are stored and further preferred that at least one value assigned to one of the at least one signature 22 preceding signature 22 is deleted from the memory before or during the value associated with the at least one signature 22 in the memory is deposited. This memory is preferably designed as a ring memory or as a shift register memory.

Depending on whether the at least one device 08; 13; 14; 16; 23 should respond to situations of individual signatures 22 or whether general Lagetendenzen many consecutive signatures 22 to be balanced, either the at least one correction signal from each exactly one stored in the memory deviation signal is determined, this deviation signal other than a last deposited in the memory Deviation signal is, or is at least one mean value is formed from a plurality of simultaneously stored in the memory deviation signals and from this at least one mean value determines the at least one correction signal.

Depending on whether a position of each signature 22 should be included, or only a sample, for example, every second, third or general n-th signature 22 is to be considered randomly, is either after a determination of the at least one correction signal, on the basis of which the machine control the

Rotational speed and / or the rotational angle position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 regulates the position of exactly one signature 22 detected before at least one further such correction signal is determined, or after determining the at least one correction signal, on the basis of which the machine control the rotational speed and / or the rotational angular position of the at least one first drive motor of the at least one first device 08; 13; 14; 16; 23 regulates the positions of at least two signatures 22 detected before at least one further such correction signal is determined.

In one embodiment, the method is further characterized in that both the rotational speed and / or the rotational angle position of the at least one first position-controlled drive motor of the at least one first device 08; 13; 14; 16; 23 as well as a rotational speed and / or an angular position of the at least one second position-controlled drive motor of the at least one second device 08; 13; 14; 16; 23 is regulated. In general, at least one, an angular position of the at least one first position-controlled drive motor

characterizing position signal and at least one, a rotational angle position of the at least one second position-controlled drive motor characterizing position signal sent to the machine control. These can then each represent at least a second signal or together represent the at least one second signal, depending on whether only the at least one first drive motor or the at least one second

Drive motor to be controlled by the method. However, the method is particularly simple if the rotational speed and / or rotational angle position of precisely one first position-controlled drive motor of at least one and preferably exactly one first device 08; 13; 14; 16; 23 is regulated. Under an angular position of a conveyor belt 14 is a position of the conveyor belt 14 to understand, for example, a full angle to a total circulation of

Conveyor belts 14 corresponds and partial revolutions can then be assigned proportionally angles. The same applies to belt control systems 14.
