Furthermore, the present invention relates to a process for the preparation of a primary part an electrical linear drive with the features of the preamble of claim 9th

It is known in manufacturing printing machines, for. Example, in printing machines, to the . Processing printing material, for example, printing material (hereinafter: Arch), by means of a Transportation system to transport based on electric linear actuators.

It is also known, in in processing printing machines such. B. Web presses, a printing material to be processed (hereinafter web) by means of a transportation system based on electric linear actuators before collect actual printing process in the machine.

It is further known to combine transport systems to branch and / or and equip for this purpose with switchable points. Since the consecutive The carriage of the system often have only small distances between each other, it is necessary to provide switches with short switching times and high switching dynamics.

Known switches have the mechanically active or mechanically passive shunt be formed, that is, they include altering the roadway moving mechanical Components, z. B. rail sections, or not.

Document DE 196 21 507 Cl discloses a web-threading device for web-shaped Material with a mechanically active crossover. The device in this case has a Guide rail, in which a pulling device for pulling the web is movable on. The propulsion is generated by an electric linear drive, which consists of a stator trained as cores magnetizable material electromagnet with each question having wound coils. The cores may be connected to each other via pole plates. The linear actuator further comprises a runner on the drawbar, on which two or more Permanent magnets or closed electrically excitable coils are mounted.

The traction device can be formed as elongated link chain whose length is greater than the distance between two adjacent coils configured as drive stations.

The apparatus further comprises one or more selectable switches, each of are designed as a rotatable disc, on which in each case in different directions curved portions of the guide rail are arranged. Depending on the Rotational position of the disc, a web path be set for the entry of the train.

When switching the switch only portions of the guide rails are moved. The Drive stations remain stationary.

The turnout described only in connection with the formed as a link chain to be used traction device because in the field of soft no drive stations are to proceed, and thus present the pulling of the switch or downstream must be detected drive stations drivingly.

a transport system for sheet is known from EP 0907515 B1. In the Document is proposed in a sheet-fed offset printing machine to electrical Linear drives provide based transport system, which at the bow means arranged propulsion elements and designed as a gripper trusses sheet holding means transported from a first to a second printing unit.

They may consist of individual members of formed as link chains, the rotor of the drive forming propulsive elements of magnetic material, eg. as permanent magnets. The the stator of the drive forming drive stations contain known electromagnetic Coils, an electromagnetic traveling field for driving the propulsion elements produce.

The transport system comprises a guide device with a mechanically passive crossover on which can be formed for instance by two additional drive stations, which are arranged at the beginning of a respective branch path of the conveyor system and which are energized according to the einzuschlagenden path alternately (ie selective activation and deactivation of electromagnetic fields in parts of the transport path to Generating cornering forces), whereby the propulsion elements in one or the other path to be promoted.

The proposed solution has the problem that the proposed design of the Soft as a mechanically passive crossover, ie without moving components, namely a fast switching of the switch and an undercut arrangement which branching paths allowed, but in terms of the guidance accuracy of Propulsive elements in the field of soft compared to the rigid guide at mechanically active switches may be undesirable limited.

Furthermore, passenger transportation systems are based on known electric linear actuators, where switchable points for branching the transport paths are provided.

Such a system is described in each of JP 59-6763 A and JP 5-140903 A. The switchable points described therein are designed such that not only Guiding devices, such. As rail sections are moved, but with these together also the stator of the drive. Thus, such a system the problem massive elements are moved that to switch out or make the switch need so that rapid switching of the switch with short switching times impossible, appears. A slow switching appears in the field of passenger transport systems but acceptable as the individual features of the system large distances from one another exhibit.

Furthermore, in the field of passenger transport systems based on electrical Linear drive (z. B. the Transrapid) also known pivoting or bending points, at which both the rail sections and the stator are moved by bending.

However, this requires high actuating forces and long travel ranges are required, low to Dynamic response leads.

Finally, the exchanging is the entire section of the transport system including rails and stator in the region of the diverter possible, but also due the masses to be moved no high switching dynamics allowed.

The carriages 14 are on a return section 16 the transport system 10 led to the unit 4 back.

For ease of illustration in Figure 1, only one guide means 12 shown. However, the transport system can preferably opposite Guide means comprise on each side of the printing press, which for guiding the carriage 14 essentially follow the same web path.

Figure 1 it can be seen that the transport system comprises a switch 18, to which a the first path 20 of the guide means 12 in a second and third path 22, 24 of Guide means 12 branches. The switch is thus at a branch of the Transport path arranged.

Figure 2 shows a sectional view of the transport system 10. Here, for the simplified Illustration, only one side end portion of a carriage 14 and this end section leading guide means shown 14, of which z. B. to a side wall Press 1 or the printing unit 2 may be arranged. The car, however, can with its opposite other (not shown) side end portion also be guided in a guide means, which preferably at the opposite wall of the printing machine or the printing unit is arranged.

The guide device 12 of the transport system 10 includes two spaced apart Rails 30, 32 (which extend in the figure in the drawing plane), between which a primary part 34 is a linear electric motor arranged 36th The secondary part 38 the electric linear motor 36 comprises the formed as a runner carriage 14, a Section 38 of the carriage 14 or arranged on the carriage 14 element 38. Alternatively, forms the carriage 14, a portion 38 of the carriage 14 or arranged on the carriage 14 Element 38, the secondary part 38 of the electric linear motor 36th

The carriage 14 is supported via wheels 40, 42, 44, 46 to the rails 30, 32 in such a way from that the car both in a vertical direction 47 and in the lateral direction 48 to is guided track sections ensure that substantially no movement can execute, and toward the rail course moved (in the figure in the drawing plane) is.

In Figure 3, the transport system 10 according to the invention is illustrated in the region of the diverter.

As area of ​​the switch, the range can be understood along the Guide means 12 substantially via the branching of the guide means 12 away covers. In this case, a respective portion of the first, second or third Path 20, 22, 24, which forward the branch directly or downstream, is also are counted to the area of ​​the switch. In particular, as a region of the diverter of Region of the transport system can be understood in which the transport system, Guide means or the primary part of the electric linear drive elements comprising crossover.

In a narrower sense than can the field of Soft only the area to be understood in which, as further below explained, rails of the guide device by recesses (Alternative name: openings) which are provided in the primary part is guided, will.

Between the rails 30, 32, the primary part extends recognized 34 of the electric Linear actuator 36 and is supported on the rails, the movable (alternatively: movable, movable or vortreibbare) carriage 14 shown.

3 shows at the same time to the two possible paths 22, 24 of the carriage 14 Leaving the diverter 18. The exact position or positioning of the rails 30, 32 in Area of ​​the switch is clearly illustrated in the other figures.

As Figure 3 can be seen from the primary section 34 sets out in path direction successive winding cores 60 (alternative designation: windings, pole elements or stator) along which to carry windings (see Figure 9) are designed. In the crossover 18 at least have some hubs or Teeth 60 (completely or partially) a smaller height, such that a recess 62 in Primary part 34 is formed in which portions or segments of the rails 30, 32 are added or receivable, z. B. by arranging, pivoting and / or linearly moving or by replacing (see also Figure 4).

The recesses permit the free passage of the rails 30, 32 by the primary part 34 in the region of the diverter 18th

In Figure 4 is illustrated by arrows, as the bodies of the switch 18 by pivoting and / or linear moving segments or by exchanging segments of Rails 30 can be achieved 32nd

By common pivoting and consequently exchanging segments 300A, 300B and 302A, 302B may be between outgoing path 22 (straight direction) and leaking path 24 (branch direction) adjusted or changed. The segments 300A, 300B show in Figure 4 the position for straight guidance during the segments 302A, 302B in Figure 4, the position of curves guide show (this representation is only show the different setting options in the application are both Segment pairs made uniform, either in straight-ahead or in direction of the curve).

The respective segments 304, 306 of the two rails 30, 32 can be prepared by linear Aufund Reciprocate between two positions to be adjusted, or wherein in the lower lowered position recesses are released for the wheels of the car, so that the carriage of a curve can be followed through to path 24 while in an upper or raised position the rails in straight direction substantially without gaps So that the car ahead can be closed are routed to path 22nd

Furthermore, the segments 308, 310 from a respective bottom can in a particular be pivoted up position and / or linearly moved. In doing so the segment 308, 310 in its lower position the straight-ahead direction freely, while in its upper or she Close raised position gaps in the rails 30, 32 in the branching direction.

Other segments shown in Figure 4, the rails 30, 32, in particular in the field of Soft are stationary.

The segments described are by a segmentation of the guide device in Movement direction is formed.

In the illustrations of Figures 5 and 6 is to detect which segments in which Position to the position of the switch in the straight direction (first position of the switch) to be ordered.

In the representation of Figures 7 and 8 is to identify which segments in which Position to the position of the switch in branch-direction (second position of the switch) to be ordered.

In the first position of the switch, the segments 300A and 302A are in their respective active position, as well as segment 304. In contrast, in the second position the Soft segment 300B, 302B and 310 active in their respective position. Active Position is to be understood so that the affected parts of the segments rail history are. In a corresponding passive position (or parking position), the affected Segments not part of the rail history.

In Figures 5 and 7 are also fixed in a recess 62 of the primary part arranged guide segments 400, shown 402nd

The sectional view shown in Figure 9 by the primary part 34 allows the hubs 60 from detect magnetizable material, wherein the area of ​​the switch 18 two hubs 600, 602 relative to the height H of winding cores 604, 606 outside the range of Soft 18 less (or: reduced or reduced) height H 'have. Thereby results in a recess 62 of the height h by which the rails 30 (or 32) can run unimpeded.

The hubs 60 of the primary part 34 - both those of the height H as well as those the height H '- are preferably only up to a uniform height H "of Windings 608 (or coils) surrounded, the height H "&lt;= H 'is Windings 608th can be fixed by arranged on the winding cores 60, nose 610, whereby the Lugs 610 preferably on all winding cores 60 at the same level (essentially H ") are arranged. The tabs 610 may further of projections on the winding cores 60 are formed.

9 shows further also designed as a carriage or slide 14 Abutment 38, that the rotor of the drive, which are spaced apart by an air gap 37 from Primary part 34 is arranged to be movable. In the illustrated example the carriage 14 to Coupling at least one permanent magnet 33 (alternatively: a rotor cage a Asynchronous) arranged. Instead of the permanent magnet 33 can also magnetizable winding core and an electrically excitable coil be provided. The Windings 608, in particular three-phase windings of the primary part 34, ie the stator, With the corresponding energizing a traveling magnetic field, ie a field which is traveling along the primary part 34, to which the magnetic field of the Permanent magnet 33 coupled and by which the permanent magnet 33 and thus and the carriage 14 carried along in the movement direction 35 in known manner and is advanced.

Although not shown in Figure 9, the primary part may 34 (and in particular the Winding cores 60) consist of many layers of mutually insulated electrical sheets and form a stator lamination. The advance movement of the carriage 14, in a conventional manner by unillustrated control or regulating devices, which energized the the windings control or regulate, be influenced in the desired manner 608, ie the Cart 14 may be accelerated or decelerated z. B., constant speed, moving distance holding to another car or in register.

Primary members 340 outside the range of the switch, in particular in the paths 20, 22 and 24, may have windings 609 in a conventional manner, the substantially use full height of the hubs 620 and thus have an optimal filling factor and generate a larger magnetic flux density in the gap. In this way, in advantageously be achieved only in the field of soft high winding cores low fill factor are used.

The primary part 34 illustrated in Figure 9 may be part of a switch device, so that the in this application as used "within the range of the switch" and such can be understood that it is meant the region of the soft component, while the primary part 340 may be part of a (soft loose) path component, so that the in this application as used "outside the range of the switch" and such can be understood that it is meant the region of the track member.

The point operating unit shown in the figure 10 70 (front view) includes a Linear guide 72 (with track 73) for a mounting member 74 (alternative designation: Base plate) is disposed on which the segment 302B of the rail 32nd At a Conversion or the switching of the switch 18, the segment 302B from its active Position linearly along the linear guide (in the figure above) in its passive position be moved. This movement is illustrated by the arrow 76th It takes the linear adjustment movement substantially perpendicular to the direction of the incoming path 20 and place in the 30, 32 spanned by the two rails level.

Thereafter or simultaneously also substantially, the segment 302A from its passive Position (in figure 10 behind the mounting plate 74, not visible) linearly along a Linear guide (in the figure forward, see the movement direction 78) from its passive Position are moved to the active position. This adjustment is carried out in substantially perpendicular to the direction of the incoming path 20 and perpendicular to that of the two rails 30, 32 spanned plane.

Likewise, the segments 300A, 3 (10B (see also Figure 11) by means of Linear guides 80, are adjusted 82nd

The segments 304, 310 can by means of linear guides alternately passive in active positions and moved back.

In Figure 11, the point operating unit is shown from behind (rear view), wherein segment 300B can be seen in its passive position.

It is also possible, instead of the horizontal and vertical adjustment devices for the Segments provide also skewed oriented actuators.

In the figures 12, 13 and 14 is a simulation calculation of the magnetic flux density B shown only partially wound winding core for a relative to its height.

Figure 12 shows a detail of a simulated winding core 90 and over located, separated by an air gap 92 of winding core 90 (spaced) Permanent magnets 94 and the field lines 96 of the magnetic flux density B in this Neck. The gray values ​​used in the figure indicate the magnitude of the magnetic Flux density at B. The digits 0 and 5 indicate the position in the air gap, as described in Diagram is plotted in Figure 13 on the abscissa.

In Figure 13, a diagram is shown, in which the magnetic flux density B (in Tesla) on the position in the air gap 92 (see paragraphs 0 and 5 in Figure 12) for different free height of the hub is plotted 90th As a free height of the hub is the portion of the winding core to be understood which is not wrapped by a coil. One can clearly see that the variable (see various drawn curves), only partially wrapping the winding core only a minor influence on the magnetic Flux density B has. Further, the magnetic flux density in excess of about 3/5 of the gap region is (0 to 3) substantially constant.

In Figure 14, a diagram is shown in which the mean relative flux density (in Tesla) is applied over the space factor (in%). As "fill factor" is the percentage Proportion of the height of the wound winding core to the overall height of the winding core to understand. It can clearly be seen here that the average relative flux density with increasing fill factor to 100% converged, from about filling factor = 25% over 90% and is reached already at about 50% filling factor = about 100% of the maximum flow.
