Definitions
- the invention relates to a method for folding a number of flat objects, which in particular individually follow each other, with the help of a device according to the Schwertfalztex and a device for controlling a drive of a folding blade for folding a number of flat objects, which in particular individually to each other consequences.
- a working according to the Schwertfalztex folding unit has two opposite in operation rotating, parallel with their axes of rotation folding rollers and a parallel to the Falzwalzenspalt arranged folding blade on.
- the folding sword is perpendicular in direction movable to the plane defined by the folding roller axes, the folding blade and the Falzwzwaltspalt lie in a plane which defined by the Falzwalzenachsen Plane at right angles intersects.
- the folding sword movement perpendicular to the plane of the flat object the flat object between the two folding rollers are beaten into the folding roller gap.
- the vertical, typically one-dimensional sword movement can vary will be realized.
- a drive can be used, which directly or indirectly is tapped from the main shaft of the folding machine.
- the Drive system can in various ways the necessary movement of the Execute folding blade:
- the sword movement can be cam-controlled or but be realized by means of a sliding-crank mechanism.
- the Drive with constant drive speed which is proportional to the Machine speed increases when transmitted directly from the drive shaft.
- there are different folding ratios for different ones Speeds there are different folding ratios for different ones Speeds.
- a major disadvantage of such drive systems is that with mechanical drive elements only a general, for all flat objects one Production-free uniform movement or speed profile of the Folding sword is realized. At the same time the amplitude, in other words the Position of the dead points of the movement clearly defined.
- a synchronization of the sword movement on the passage of the flat objects can clock bound, ie in forced operation with the clock frequency of the folding machine, or unblocked, in other words event-driven.
- DE 33 25 139 discloses how a folding blade control such is carried out that the flat object at the time in the Folding roller pair is hammered when its leading edge stops in the folder has reached.
- a detector element or a sensor is at one of the length of the planar Object appropriate distance set to the stop in the folder.

- the present invention is based on the object, a method for folding a Number of flat objects and a device for controlling a drive of a To propose folding blade, which have a reduced wear during operation and a high precision at higher clock frequencies with which operated the folding machines becomes possible.
- the solution combines the advantages of the clock - controlled and the event - controlled drive of the Folding knife.
- controllable single drives for example of Linear drives, pneumatic servo axes, hydraulic servo axes or the like. It is possible, by appropriate specification, desired individually to realize customizable movements of the folding sword. So it can be a direct to the Parameters of the production lot, in particular the machine, process and Material parameters, pass through the adapted speed profile of the folding blade become.
- the speed profile of the folding blade has at least two Shares on the one hand to the already described cyclic, essentially periodic Share, which is typically anharmonic, and another share, which makes it possible to celebrate the event of the individual entering the fold flat object to be considered.
- Particularly advantageous is an anharmonic Movement, which is divided into a forward and backward movement of the sword.
- anharmonic Movement which is divided into a forward and backward movement of the sword.
- the arrival time of the flat object under the Falzhist be precalculated so that the triggering time for the Speed profile of the folding sword, which either from known Velocity profiles selected or calculated for the current operation, can be determined.
- the arrival time a second, late time of the flat object with known Acceleration of the object on the way to the device for folding be calculated in advance.
- the speed profile is generally different Machine parameters dependent.
- the parameters include aspects of Suction stroke control, which depends on the sword drive.
- the necessary speed profile for a particular flat object under the Folding sword a superposition of a cyclic share and at least one further share, which is adapted to the individual flat object.
- the time course is free of intervals on which the Velocity profile is completely zero.
- Another advantage of the method and the invention Device is that the cyclic movement within the folding unit according to the invention regardless of the required cyclic movements in other folders Machine is because the cyclic movement of the folding blade in the invention Folding unit to the clock frequency of the flat objects entering this folding unit, which in particular individually follow each other, given on average and at the same time is designed individually, so that takes into account scatters around a mean phase can be.
- the method according to the invention and the Inventive device combine the advantages of a clock-bound with a event-based control.
- Another advantage of the device according to the invention is that the individual configurable minimum distance between folding blade at the reversal point and folding rollers in particular the length and / or width and / or thickness of the flat article can be adjusted.
- a dead time compensation that is a compensation the time between the signaling at the beginning of the movement and the actual beginning of the movement passes, be carried out. The dead time is down others the components of the switching time of the drive unit and the slip time of the Folding sword on.
- the Triggered movement of the folding blade can in this case by reversing the direction of rotation and / or by slowing down the movement by reversing other, special speed profile is going through.
- Advantageously switched The machine turns off to prevent unwanted stopping in an inaccessible place Machine to avoid, and so that the rolled flat object directly removed can be.
- Fig. 1 shows the schematic structure and the topological context of individual units, which the inventive device for controlling a Drive a folding blade comprises and the implementation of the invention Procedure allowed.
- On the transport device 10 is at least one area Article 12, which has a speed V, in the direction of transport A to the Inventive device introduced. He passes the position of one Detector 14 at a known distance D to a point of the means for folding, for example, to the front stop 36, after the Schwertfalztex, which by the Presence of the object generates at least one signal that is connected to the Exchange of data and / or control signals 16 to the computing unit 18 transmitted becomes. Between folding blade 34 and detector 14 in a known distance D can possibly even more modules are.
- the speed V can thereby According to the invention, either from the knowledge of machine parameters, such as clock frequency, Throughput or the like, derived or calculated, or the speed V can be measured locally with a known distance D.
- the help detector 14 detects the presence of two points of known distance, For example, the leading and trailing edge, the flat article 12 performed and the times of both events of presence are determined.
- the speed V As is known, this is calculated from the difference quotient.
- the Device in an advantageous development of the invention at least one other Detector with also known, necessarily not equal distance D as the Have detector 14 to the means for folding, so from the passage of the same Point, for example, the leading or trailing edge of the sheet-like object 12th at different times the speed with the help of the difference quotient can be calculated.
- the time of arrival of the flat object 12 at the Device for folding and thus the triggering time of the folding blade movement be calculated.
- Correction values such as those due to a Transport slippage or the like may be required, may be considered.
- the main influences on the motion of the plane Item 12 are substantially known so that with the initial conditions Distance D and velocity V with essentially known motion law the Speed profile of the flat article 12 with sufficient precision determined between the location with known distance D and the means for folding can be.
- the device for folding according to the Schwertfalztex be calculated so that a determination of the time of triggering the movement of the folding sword is possible.
- the necessary speed profile for the Falzhist 34 either calculated or stored speed profiles selected, which advantageously in a data storage unit 22, the one Connection to the exchange of data 20 to the arithmetic unit 18, are deposited.
- the arithmetic unit 18 has a Connection for exchanging data and / or control signals 24 to a human-machine interface 26, which is typically a display and an input unit includes, on.
- the machine operator can use relevant data information, such as For example, machine, process, material or correction parameters and the like, directly to the computing process.
- About the connection to the exchange of Data and / or control signals 28 is the arithmetic unit 18 with the drive unit 30 of the Folding sword connected.
- Wirkharm 32 Between the drive unit 30 and the actual folding blade 34 is a Wirkharm 32, which different characteristics, such as transmission parts, rods and may have the same.
- a typical sword drive with servomotor either has one Thrust gear or a gear rack combination on.
- the folding sword 34 performs a cyclic one-dimensional motion whose direction is denoted by B. is.
- B. is.
- the flat object 12 when he am Front stop 36 has arrived, in a direction substantially perpendicular to Transport direction on the gap between the folding rollers, one, 38, in this View is visible and the other hidden behind it lies in the paper plane, pressed.
