Description

The invention relates to a cutting device with a cutting tool.

From the EP2551077A1 a cutting device is known in which connecting parts of a cutting tool are mounted so as to be linearly displaceable, so that the cutting tool can be displaced back and forth along a straight line in order to carry out cutting movements. The cutting tool is held on both sides by a guide device with two guide modules, by means of which the connecting parts of the cutting tool are guided and mounted in a linearly displaceable manner along a path. Drive modules are also provided, by means of which the cutting tool is moved along the paths. The drive modules are synchronized with one another by means of a control device, so that the cutting tool remains horizontally aligned when the cutting movements are carried out.

The cutting tool or the metal blade is connected to an ultrasonic generator via a coupling element and an energy converter. During the cutting process, ultrasonic energy is applied to the metal blade so that the cutting process can be carried out with reduced resistance.

If the metal blade is not subjected to ultrasonic energy, as is the case with conventional cutting devices, the process material to be cut is compressed more strongly during the cutting process than when using ultrasonic energy. Under the action of the cutting tool, the elastic process material is deformed, which is less when ultrasonic energy is used. The deformation of the process material can adversely affect the cut pattern. If, on the other hand, the process material is hard and possibly also brittle, it can possibly break under the action of the cutting tool.

The described problem of the deformation of the process product also requires a limitation of the clock cycles, since the forces acting increase correspondingly with increased speed of the displacement of the cutting tool.

Due to the forces acting on the process material and acting back from the process material on the cutting tool, a higher result also results Stress on the cutting tool, which leads to higher maintenance costs and an earlier replacement of the cutting tool.

The present invention is therefore based on the object of creating an improved cutting device.

In particular, a cutting device is to be created which has a simple structure and at the same time provides improved cutting results.

Any process material should advantageously be cut by means of the cutting device. Deformation, in particular compression, of the process material should be avoided. Correspondingly, cutting processes should be carried out precisely and improved sectional images achieved largely independently of the nature of the process item.

The cutting processes should be able to be carried out with higher clock cycles.

The cutting device should have a compact design and take up little space so that it can be advantageously integrated into any production process.

The cutting device should be able to be produced with reduced effort. In particular, guide devices and drive devices for the cutting tool should be constructed in a simpler and more cost-effective manner.

This object is achieved with a cutting device which has the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

The cutting device comprises a tool drive, a cutting tool with a first connection part, which is connected to a first driver, and with a second connection part, which is connected to a second driver, and a guide device, which has a first guide unit with a first guide module and a second Has guide module, by means of which the first driver along a first guide track and the second driver is held displaceably along a second guide track.

1. a) die von zugeordneten Lagervorrichtungen in einer Führungsebene je drehbar gehalten sind;
2. b) die an einer ersten Übergabeposition peripher aneinander angrenzen;
3. c) die je peripher eine nach aussen geöffnete Aufnahmeöffnung aufweisen, die zur Aufnahme des ersten Mitnehmers geeignet ist;
4. d) die vom Werkzeugantrieb mit gleicher Winkelgeschwindigkeit in entgegengesetzte Richtungen drehbar sind;
5. e) die derart angeordnet sind, dass deren Aufnahmeöffnungen nach jeder Umdrehung an der ersten Übergabeposition einander gegenüber liegen, sodass der betreffende Mitnehmer jeweils an der Übergabeposition zwischen den beiden Führungsräder alternierend von der einen in die andere Aufnahmeöffnung überführbar ist und alternierend entlang der Peripherie des ersten Führungsrads oder des zweiten Führungsrads weiter führbar ist.

According to the invention, the first and / or the second guide module has two guide wheels,

1. a) which are each rotatably held by associated storage devices in a guide plane;
2. b) which border one another peripherally at a first transfer position;
3. c) each having an outwardly open receiving opening at the periphery, which is suitable for receiving the first driver;
4. d) which can be rotated in opposite directions by the tool drive at the same angular speed;
5. e) which are arranged in such a way that their receiving openings lie opposite each other after each rotation at the first transfer position, so that the respective driver can be transferred alternately from one to the other receiving opening at the transfer position between the two guide wheels and alternately along the periphery of the first Guide wheel or the second guide wheel can be continued.

During the operation of the cutting device, for example, the first driver in the first guide module is therefore alternately guided in a guide path, first around the first guide wheel and then around the second guide wheel, which rotate synchronously in opposite directions. The resulting guideway corresponds to an eight. The first driver and thus the associated connection part of the cutting tool is thus moved back and forth in a first direction by twice the diameter of a guide wheel and in a second direction perpendicular to the first direction by the single diameter of a guide wheel during one revolution around the guide track.

During this process, the second driver in the second guide module can be moved along an identical, linear or curved guide path. The second driver can follow the movements of the first driver passively or slavishly. For example, a linear or curved guide channel is provided in the second guide module, along which the second driver can follow the movements of the first driver. The deflection of the cutting tool can be determined accordingly by dimensioning and aligning the second guide channel accordingly.

1. a) die von zugeordneten Lagervorrichtungen drehbar gehalten sind;
2. b) die an einer zweiten Übergabeposition peripher einander gegenüber liegen;
3. c) die je peripher eine nach aussen geöffnete Aufnahmeöffnung aufweisen, die zur Aufnahme des zweiten Mitnehmers geeignet ist;
4. d) die vom Werkzeugantrieb mit gleicher Winkelgeschwindigkeit in entgegengesetzte Richtungen drehbar sind;
5. e) die derart angeordnet sind, dass deren Aufnahmeöffnungen nach jeder Umdrehung an der zweiten Übergabeposition einander gegenüber liegen, sodass der zweite Mitnehmer jeweils an der zweiten Übergabeposition alternierend von deren einen in die andere Aufnahmeöffnung überführbar ist und alternierend entlang der Peripherie des ersten Führungsrads oder des zweiten Führungsrads des zweiten Führungsmoduls weiter führbar ist.

However, it is preferably provided that the second driver is also actively guided in the same way as the first driver. This will be it is provided that the second guide module also has a first guide wheel and a second guide wheel,

1. a) which are rotatably held by associated storage devices;
2. b) which lie peripherally opposite one another at a second transfer position;
3. c) each having an outwardly open receiving opening peripherally which is suitable for receiving the second driver;
4. d) which can be rotated in opposite directions by the tool drive at the same angular speed;
5. e) which are arranged in such a way that their receiving openings lie opposite each other after each rotation at the second transfer position, so that the second driver can be transferred alternately from one to the other receiving opening at the second transfer position and alternately along the periphery of the first guide wheel or the second guide wheel of the second guide module can be continued.

The first and the second guide module are thus preferably of identical design, preferably arranged within a guide plane, optionally rotated by 180 ° relative to one another and spaced apart from one another according to the length of the cutting tool.

The axes of rotation of the running wheels of the first guide module and the running wheels of the second guide module preferably define the corner points of a rectangle or a parallelogram at the points of intersection of the guide plane.

The first driver and the second driver run synchronously in spaced apart identical and identically aligned guide tracks, possibly guided in rival guide channels.

The guide wheels can be guided at high speed so that a process material can be cut with high cycle times.

During the cutting process there is a cutting movement in two directions. The cutting tool always remains aligned parallel and is cyclically downwards and downwards with a first cutting movement along its longitudinal axis moved up. At the same time, the cutting tool is moved back and forth perpendicular to it with a second cutting movement. With the first cutting movement, the cutting tool can be guided tangentially along the process item, while the cutting tool is guided simultaneously with the second cutting movement against the process item or into the process item in order to separate it. With simple rotational movements of the guide wheels, an ideal cutting movement can thus be carried out, which allows the material to be processed to be cut precisely and quickly.

The process material is separated by the first cutting movement so that the process material is not compressed by the second cutting movement. Due to the avoidance of the compression of the process material, precise cuts and precise cutting patterns result. Process goods, in particular food such as meat, bread, cheese, or other industrial goods can thus be cut optimally, i.e. extremely precisely and with high cycle times.

If the cutting tool is designed as a wire or a blade that has cutting edges on both sides, the process material can be cut from both directions by means of the wire or the blade, which doubles the cycle frequency of the cuts.

If a wire is used as the cutting tool, it is preferably rotatably mounted and driven by means of at least one tool motor. Both wire ends or connection parts of the cutting tool are preferably connected to tool motors, so that torsion of the wire is avoided and the wire can be rotated at the highest speeds. The wire can execute rotational speeds, preferably optionally or optionally adjustable by the control unit, between zero and over 1000 revolutions / s, which results in a high cutting performance. The rotating wire can be inserted into the process material with practically no resistance.

The guide device described so far has only a first guide unit which is practically aligned in a first guide plane.

To increase the performance and stability, the guide device is preferably equipped with a first guide unit and a second guide unit. The second guide unit is preferably designed as a mirror image of the first guide unit and is located opposite this in a parallel guide plane, preferably frontally. The axes of rotation of the guide wheels of the first and second guide units are preferably aligned coaxially with one another. The distance between the two guide units and thus the distance between the two guide levels is preferably selected according to the dimensions of the cutting tool and associated equipment, such as tool motors or ultrasonic transducers, which are held and guided between the two guide levels or guide units. The guide units are preferably identical and can be manufactured with minimal effort.

In this embodiment, the cutting tool is held on both connecting parts, which is why there are no bending stresses and torsions. The cutting tool can be guided powerfully without overloading.

In each of the configurations described, the guide device can be made extremely compact. The dimensions of the guide units are determined by the dimensions of the cutting tool and by the deflection of the cutting tool in said first and second directions of movement. It only takes up as much space as the cutting tool itself needs. The guide units themselves can be manufactured with a small thickness of, for example, about 1 cm to 2 cm. A more compact structure is therefore hardly possible.

The cutting device according to the invention can therefore advantageously be integrated into any processes and devices in all configurations. Due to the compact design, the cutting device can also be integrated in vending machines that cut a process item to be sold. For example, the cutting device is combined with a conveyor device that cuts bread or cakes. The conveyor device can also introduce different process goods sequentially into the cutting process, so that, for example, bread is cut first, then meat and then bread again. In this way, fresh sandwiches can be cut automatically.

The mirror-image or symmetrical structure of the guide device, which uses essentially the same device parts for all guide modules, is particularly advantageous. For example, identical Guide wheels are used, which are only to be coupled to one another in pairs in a suitable alignment.

The cutting device according to the invention can have a modular structure and can be assembled in a few simple steps.

The guide wheels can be driven in various ways. The tool drive preferably comprises a single drive motor, by means of which all guide wheels of the guide device are driven via a correspondingly designed power transmission device. The power transmission device can comprise gear wheels and / or toothed belts coupled to one another. Furthermore, a drive module can be assigned to each guide unit or to each guide module or to each guide wheel. In this case, the synchronization of all guide wheels must be ensured. For example, the positions of the guide wheels are determined by means of sensors and corrected if necessary. The drive can be done by stepper motors, which control the assigned guide wheels accordingly.

The drive of the guide wheels is particularly simple if they are designed as gear wheels and have peripheral teeth. It is sufficient to drive only one of two toothed wheels. These are automatically synchronized by the corresponding toothing of the guide wheels. In this case, the pairs of guide wheels can also be driven with little effort by a single drive motor through transmission shafts and gears.

The tool drive can therefore easily be set up in a centralized or decentralized manner.

After each revolution of the guide wheels, the drivers and the receiving openings of the guide wheels reach the associated transfer positions. At this transfer position, the receiving openings are opposed to one another, possibly with a slight gradient. Due to the moving mass, the drivers try to continue their path in a straight line at the transfer position, which runs from the first guide wheel in the direction of the adjacent guide wheel. At the same time, centrifugal forces act which cause the drivers to enter the receiving opening of one guide wheel into the receiving opening of the other guide wheel. In this way, the drivers and the associated cutting tool are automatically transferred.

The transfer of the drivers from the receiving opening of one guide wheel to the receiving opening of the other guide wheel is supported in preferred embodiments by additional guide elements that can be used individually or in combination.

In a first preferred embodiment it is provided that a preferably at least approximately V-shaped first guide collar is arranged on the receiving opening of the first guide wheel and a second, preferably at least approximately V-shaped guide collar is arranged on the receiving opening of the second guide wheel.

The first guide collar is preferably designed in such a way that it projects beyond the first guide wheel and engages in the second guide collar at the transfer position. In the transfer position, the two guide collars define a possibly self-contained transfer channel along which the associated driver is safely guided from the receiving opening of the first guide wheel to the receiving opening of the second guide wheel.

Rotatably mounted magnets can also be provided as auxiliary elements, which magnets attract or repel the drivers or magnets directly or indirectly connected to them in order to hold them in the receiving openings or to eject them therefrom.

In a preferred embodiment, the first and / or the second drivers of the first and the second guide unit are connected to one another by a first guide shaft. The guide shafts can fulfill various functions. On the one hand, the guide shafts can be used to support the drivers, which, for example, are designed as hollow cylinder elements and can rotate around the guide shafts. The guide shafts preferably protrude beyond the drivers on both sides, depending on the outside, and are connected outside the drivers with their end pieces to a guide carriage.

So that the drivers can be moved as smoothly as possible in a guide channel along the guide track, if necessary, they are rotatably mounted in preferred configurations.

In preferred embodiments, the drivers and / or the guide carriages are guided in guide plates. Preferably, each of the guide modules has a guide plate that is used to support the associated Serves guide wheels. Each guide plate preferably has a guide channel running parallel to the guide track along which the associated driver is guided. The guide channel comprises at least one channel segment which is used for direct or indirect guidance of the associated driver.

A first channel segment is preferably provided, which serves to receive an end piece of the associated driver. The drivers are thus forcibly guided parallel to the guide track in this first channel segment.

As an alternative or in addition to the first channel segment, a second channel segment is preferably provided, which is intended to accommodate an elongated and rotatably mounted guide carriage that is connected directly or indirectly to the associated driver. The guide carriage can be connected to the driver directly or indirectly, fixedly or rotatably. In contrast, the guide carriage is preferably fastened to the guide shaft which accordingly projects beyond the driver. The guide carriage is guided largely straight along the guide track in the guide channel or in the second channel segment, so that it always runs diagonally through the intersection, which is located at an assigned transfer position. In this way, the guideway is always traversed smoothly and correctly.

A third channel segment into which the guide wheels are sunk is preferably provided. The lowering of the guide wheels has the effect that drivers held in the receiving openings cannot exit the receiving openings outside the transfer position.

The connecting parts of the cutting tool can be connected to the drivers as required. Articulated connections are preferably provided. In a preferred embodiment, the first and second drivers are connected directly or indirectly, for example by means of a bearing block, to the associated first or second connection part of the cutting tool.

Any auxiliary devices can be attached to the bearing block, in particular auxiliary devices that serve measuring purposes and / or act on the cutting tool. The cutting processes can be monitored using sensors that are moved with the cutting tool.

The first and second drivers are preferably each connected to a bearing block that holds an ultrasonic transducer, which in turn is connected to the associated connection part in order to emit ultrasonic energy to the cutting tool.

Cutting devices according to the invention can advantageously be integrated into any process chains, any devices, vending machines and the like. Process material to be cut is preferably supplied by means of a conveying device in process steps which are synchronized with the cutting cycles. For each step to be carried out, the process item is pushed into a desired position beforehand. If the cutting tool has a cutting edge on both sides or if the cutting tool is a wire, the process material can be cut from both sides. After each deflection, the material to be processed is advanced according to the required slice thickness and made available for the next slicing process. The cutting tool can therefore make a cut twice with each pass through the guideway.

Each of the guide modules 11A; 11B; 12A; 12B includes a first guide wheel 111; 121 and a second guide wheel 112; 122, the pairs of guide plates 115; 125 (see Fig. 2a ) are rotatably held. The guide wheels 111, 112; 121, 122 are designed as gears and mesh with one another with their teeth. The guide plate 115 of the upper guide module 11A of the first guide unit 1A has been cut vertically in the middle.

Of each pair of cooperating guide wheels 111, 121; 112, 122 are each a driver 118; 128 (see Fig. 2a ) and circulates along the guide loop. Coaxial with each of the drivers 118; 128 is a guide carriage 119; 129 (see e.g. Figure 3c ) intended. The end pieces of the drivers 118, 128 facing the guide plates 115, 125 and the guide carriages 119, 129 are guided in a guide channel which is each in the associated guide plate 115; 125 is arranged and runs parallel to the guide loop.

It is described and shown below that each driver 118; 128 from the associated pair of guide wheels 111, 121; 112, 122 is alternately circulated along the periphery thereof, which is why the guide track has the shape of a figure eight. The cutting tool 2 is thus cyclically guided along a roller coaster which has a crossing point or a transition point T1; T2 has (see Fig. 2a ).

The guide device 1 comprises a mounting structure 10 which connects the two guide units 1A, 1B and their guide modules 11A, 11B, 12A, 12B to one another. The two guide units 1A, 1B comprise assigned structural units 10A, 10B which are connected to one another by connecting elements 10C.

The guide wheels 111, 121 are driven; 112, 122 and the cutting tool 2 by means of a tool drive 3 which has a drive motor 30 which, via a power transmission device 31, drives the guide wheels 112; 122 (see Fig. 2a ) drives which, via their toothing, the associated further guide wheel 111; 121 drive. the Power transmission device 31 comprises gearwheels which are rotatably held by gearwheel shafts and which are coupled in a form-fitting manner on the one hand to the drive motor 30 and on the other hand to the guide wheels 112, 122. The power transmission from the drive motor 30 to the guide wheels 112, 122 can also take place by drive belts, preferably a toothed belt and, if necessary, toothed wheels, as shown in FIG Fig. 9 is shown. It is also possible to drive the guide wheels 111, 121; 112, 122 by individually assigned drive motors that work synchronously.

The guide device 1 with the cutting tool 2 can be integrated into any devices and processes in order to cut a process product P. In Fig. 1 A conveying device 4 with a pushing device 41 is shown by way of example, by means of which a process item P can be guided, preferably step by step, against the cutting tool 2. The pusher device 41 comprises a conveyor motor 40, by means of which a feed slide 411 can be displaced, preferably step by step, along a feed path 412. With the feed slide 411, feed tools 413 can be displaced against the process material P. The process material P is guided by side plates 421 and displaced against the cutting tool 2, preferably step by step, according to the cutting cycles via a feed plate 42.

The cutting device 100 preferably comprises a control unit 5, by means of which the movement of the cutting tool 2 and the pushing tools 413 can be controlled. Fig. 9 shows that the position of the cutting tool 2 is detected by means of at least one sensor 50 and reported to the control unit 5. As a result, the control unit 5 sends corresponding control signals 53, 54 to the drive motor 30 and the conveyor motor 40 in order to control the advance of the process material P in accordance with the movements of the cutting tool 2. After a cutting movement has been carried out and before the start of the next cutting movement, the process item P can be advanced by a distance which corresponds to the set cutting thickness. The control unit 5 can, for example, be a conventional personal computer.

In preferred embodiments, the control unit 5 also has an alternating voltage generator, by means of which alternating voltages in the ultrasonic range are generated and applied to sound transducers 25, which are connected to connecting parts 21, 22 of the cutting tool 2. The alternating voltages are fed to piezo elements, for example, which convert the electrical vibrations into mechanical vibrations.

Fig. 1 shows the cutting device 100 in a preferred embodiment with two upper guide modules 11A, 11B and two lower guide modules 12A, 12B. The connecting parts 21, 22 (see FIG Fig. 2a ) are held and guided on both sides in this configuration. The guide device 1 can also be designed in such a way that the connection parts 21, 22 are only located on one side in a guide module 11A; 12A are performed. Furthermore, it can be provided that only one of the connection parts 21; 22 of the cutting tool 2 on one side by one or on both sides by two opposing guide modules 11A, 11B; 12A, 12B (see Figure 5c ) and the other connection part 22; 21 follows in any path. The cutting device 100 can therefore be constructed and expanded according to the needs of the user.

Fig. 2a FIG. 10 shows the cutter 100 of FIG Fig. 1 with a symbolically shown, possibly wire-shaped cutting tool 2 and the guide device 1 with the first guide unit 1A from the perspective of the second guide unit 1B, which is only provided as an option.

The end pieces or connecting parts 21, 22 of the cutting tool 2 are each connected to a driver 118, 128, which alternates in a roller coaster along the periphery of the two mutually corresponding guide wheels 111, 112; 121, 122 can be circulated, which are held by means of storage devices 7. The bearing devices 7 include bearing shafts 71 which are in central bearing openings 70 of the guide wheels 111, 112; 121, 122 are held.

• a) grenzen an Übergabepositionen T1, T2 peripher aneinander an;
• a) sind als Zahnräder ausgebildet und greifen mit Verzahnungen ineinander ein;
• c) weisen je peripher eine zumindest annähernd radial nach aussen geöffnete Aufnahmeöffnung 1110, 1120; 1210, 1220 auf, die der Aufnahme je eines Mitnehmers 118; 119 dient;
• d) sind vom Werkzeugantrieb 3 mit gleicher Winkelgeschwindigkeit in entgegengesetzte Richtungen drehbar;
• e) sind derart angeordnet, dass deren Aufnahmeöffnungen 1110, 1120; 1210, 1220, wie in Fig. 2a gezeigt, nach jeder Umdrehung an der zugeordneten Übergabeposition T1; T2 einander gegenüber liegen, sodass die Mitnehmer 118; 119 jeweils an der Übergabeposition T1; T2 alternierend von der einen in die andere Aufnahmeöffnung 1110, 1120; 1210, 1220 überführbar sind und alternierend entlang der Peripherie des ersten Führungsrads 111; 121 oder des zweiten Führungsrads 112; 122 weiter führbar sind.

The guide wheels 111, 112; 121, 122

• a) border one another peripherally at transfer positions T1, T2;
• a) are designed as gears and mesh with one another with gears;
• c) each peripherally have an at least approximately radially outwardly open receiving opening 1110, 1120; 1210, 1220, which each receive a driver 118; 119 serves;
• d) can be rotated in opposite directions by the tool drive 3 at the same angular speed;
• e) are arranged in such a way that their receiving openings 1110, 1120; 1210, 1220, as in Fig. 2a shown after each revolution at the assigned transfer position T1; T2 are opposite one another, so that the drivers 118; 119 each at the transfer position T1; T2 alternating from one to the other receiving opening 1110, 1120; 1210, 1220 can be transferred and alternately along the periphery of the first guide wheel 111; 121 or the second guide wheel 112; 122 can be continued.

In Fig. 2a The drivers 118, 128, which have just revolved around the first guide wheels 111, 121, are held in the receiving openings 1110, 1120 of the first guide wheels 111, 121 and are subsequently guided by centrifugal forces or forced into the receiving openings 1120, 1220 of the second guide wheels 112 , 122 transfer and then rotate the second guide wheels 112, 122. Even before reaching the transfer positions T1, T2, the drivers 118, 128 can move outwards so that they are thrown into the adjacent receiving openings 1120, 1220.

Figure 2b FIG. 10 shows the cutter 100 of FIG Fig. 2a after the transfer of the drivers 118, 128 to the second guide wheels 112, 122 and a further rotation of the guide wheels 111, 112 coupled to one another; 121, 122 by 90 ° in opposite directions, after which the cutting tool 2 was moved on by an eighth of the way within the closed loop. The cutting tool 2 was not only guided to the right in the direction of the second guide wheels 112, 122, but also upwards.

It can thus be seen that the connecting parts 21, 22 of the cutting tool during a cycle corresponding to the diameter of the guide wheels 111, 112; 121, 122 deflected twice downwards and upwards and corresponding to twice the diameter of the guide wheels 111, 112; 121, 122 is moved back and forth. The cutting tool 2 thus performs a tangential movement relative to the process item while it is guided through the process item. The process material is thus cut with high precision without being compressed.

Fig. 3a FIG. 10 shows the cutter 100 of FIG Fig. 1 from the front with the guide device 1 with the two guide units 1A, 1B, between which the cutting tool 2 is held in a circulating manner within the loop. The guide wheels 111, 112; 121, 122 are mounted in pairs in upper and lower guide plates 115, 125.

The process material (not shown) is conveyed via the feed plate 42 to the cutting tool 2, which is guided back and forth in front of the feed plate 42, preferably according to the entire width of the feed plate 42.

Figure 3b FIG. 10 shows the cutter 100 of FIG Fig. 3a after removing the upper and lower guide plates 115, 125 from the second guide unit 1B. On the front side, the guide carriages 119, 129 are exposed, which are guided in guide channels provided in the remote guide plates 115, 125.

Figure 3c FIG. 10 shows the cutter 100 of FIG Figure 3b without the optionally provided second guide unit 1B with a view of the cutting tool 2, the connecting parts 21, 22 of which are held by optionally provided ultrasonic transducers 25. It should be noted that the guide device 1 can also be implemented in this configuration, ie only with the first guide unit 1A. Guiding on both sides is preferred when process material is cut with great force. The effort required to cut the process item can, on the other hand, be reduced by applying ultrasonic energy to the cutting tool 2. It is shown that the drivers 118, 128 each hold a mounting body 29 on which an ultrasonic transducer 25 is mounted. Each of the ultrasonic transducers 25 is in turn connected to one of the connection parts 21, 22 of the cutting tool 2. The connection parts 21, 22 are connected, for example, to a metal cylinder which is braced with piezo elements within the ultrasonic transducer 25. By applying electrical alternating voltages in the subsonic range to the piezo elements, ultrasonic waves are generated, which are transmitted to the cutting tool 2 via the connection parts 21, 22.

Fig. 3d FIG. 10 shows the cutter 100 of FIG Figure 3c without the ultrasonic transducer 25 with a view of the drivers 118, 128 in the position of Fig. 2a , in which they are transferred from the first guide wheels 111, 121 to the second guide wheels 112, 122. Any cutting tools 2 can be connected to the drivers 118, 128. The cutting tool 2 shown by way of example is preferably used, which has a blade 200 which is provided with cutting edges 201, 202 on opposite sides. With such a cutting tool 2, possibly also with a wire-shaped cutting tool 2 (see Fig. 5d ) a cut can be made in any direction of movement from left to right and right to left.

Fig. 3e FIG. 10 shows the cutter 100 of FIG Fig. 3d without the guide wheels 111, 112; 121, 122 with a view of optionally provided guide channels B11, B12 which are provided in the guide plates 115, 125. The drivers 118, 128 and the guide carriages 119, 129 are guided in different channel segments of the guide channels B11, B12. The drivers 118, 128 can be positively guided by means of the guide channels B11, B12. The guide carriages 119, 121 ensure that the cutting tool 2 is always continued in the correct direction at the transition positions T1, T2.

Fig. 4 FIG. 10 shows the cutter 100 of FIG Fig. 1 with a view from above between the two guide units 1A, 1B, between which the cutting tool 2 is held. The guide plate 115 of the upper guide module 11B of the second guide unit 1B was raised halfway along the in Fig. 3a drawn cutting line A - A cut horizontally. Parts of the guide channel B11 are exposed in the cut-open guide plate 115. In the area of the transition position T1, the driver 118 held in the guide channel B11 and the guide carriage 119 are shown. The storage devices 7 used are also visible.

Figure 5a FIG. 10 shows the cutter 100 of FIG Fig. 1 with the moving elements of the two guide units 1A, 1B of the guide device 1 and the cutting tool 2 in the position of Fig. 2a . The cutting tool 2 is between the first and second guide wheels 111, 121; 112, 122 of the first and second guide units 1A, 1B held by drivers 118, 128 of the two guide units 1A, 1B.

Figure 5b FIG. 10 shows the cutter 100 of FIG Figure 5a with the moving elements of the first guide unit 1A of the guide device 1. As mentioned, the guide device 1 can also be operated in this configuration. It is shown that guide shafts 1181, 1281 protrude from the drivers 118, 128. The drivers 118, 119 of the two guide units 1A, 1B are designed as hollow cylinders and are rotatably held on both sides by the guide shafts 1181, 1281.

Figure 5b further shows that the first guide wheel 111; 121 with a first guide collar 1111; 1211 is provided which the first guide wheel 111; 121 protrudes and at the transfer position T1, T2 in a second guide collar 1121; 1221 engages, which is attached to the second guide wheel 112, 122. The guide collars 1111, 1211, 1121, 1122 are V-shaped and, with two guide arms, enclose the associated receiving opening 1110, 1120, 1210, 1220 of the associated guide wheel 111, 112, 121, 122. 1211; 1121, 1122, a transfer channel TC is formed in each case at the transfer position T1, T2, via which the drivers 118, 128 are controlled from one to the other receiving opening 1110, 1210; 1120, 1220 can arrive. The guide arms of the guide collars 1111, 1211, 1121, 1122 can be shaped if necessary, so that, for example, a gradient results along which the drivers 118, 128 can roll or slide according to the acting centrifugal and gravitational forces.

Figure 5c FIG. 10 shows the cutter 100 of FIG Fig. 1 with the first guide unit 1A, optionally with the second guide unit 1B, not shown, in a preferred embodiment in which only the first connection part 21 of the cutting tool 2 is circulated around the guide wheels 111, 112 of the upper guide module 11 and the second connection part 22 in the lower guide module 12A is cyclically guided back and forth in a straight or curved, vertical or inclined guide channel B12. In principle, a self-contained second guide channel B12 running, for example, along a circle or an ellipse can also be provided. In the exemplary embodiment shown, the driver 128 and the optionally provided guide carriage are guided vertically upwards and downwards.

Fig. 5d FIG. 10 shows the cutter 100 of FIG Figure 5b with the moving elements of the guide unit 1A of the guide device 1 with a wire-shaped cutting tool 2. The cutting tool 2 is rotatably mounted about its longitudinal axis and is preferably connected to and driven by electric tool motors 211, 221 at both connection parts 21, 22.

Fig. 6 FIG. 3 shows the guide device 1 with the first guide unit 1A and the tool unit 2 with the ultrasonic transducers 25 from FIG Figure 3c in exploded view.

Figure 7a FIG. 11 shows the upper guide module 11A of FIG Fig. 3d without the first guide wheel 111 with the driver 118 at the transfer point T1 between the first and second guide wheels 111, 112.

Figure 7b FIG. 11 shows the upper guide module 11A with a vertical section along the section line B - B from FIG Fig. 6 by the guide plate 115 at the position of the driver 118. It is shown that the guide carriage 119 is correctly aligned and correctly guides the driver 118 over the intersection of the guide channel B11.

The guide channel B11 comprises three channel segments B1, B2 and B3. An end piece of the driver 118 is guided in the middle channel segment B1. The guide carriage 119 is aligned and guided accordingly in the deepest channel segment B2. The guide wheels 111, 112 are sunk into the uppermost channel segment B3. This ensures that the drivers 118, 128 only move away from the guide wheels 111, 112; 121, 122 can solve.

At the transfer point T1, the middle channel segment B1 is somewhat wider, which is why the guide here essentially takes place by the guide carriage 119.

Figure 7c FIG. 11 shows the upper guide module 11A of FIG Fig. 3d shown without the first guide wheel 111 with the driver 118 moved further by a quarter turn of the second guide wheel 112. Furthermore, the driver 118 ′ is shown in a further position within the part of the guide channel B11 in the area of the first guide wheel 111. The driver 118 was moved in a circular path in a clockwise direction around the second guide wheel 112 and introduced from below into the circular path which the first guide wheel 111 revolves.

Fig. 7d FIG. 11 shows the upper guide module 11A of FIG Figure 7c with a vertical section along the section line B - B of Fig. 6 by the guide plate 115 at the position of the driver 118, which was reached after the quarter turn of the second guide wheel 112. The driver 118 is guided here with little play in the middle channel segment B2. In this position, the guide carriage 119 is aligned horizontally in the deepest channel segment B1.

Fig. 8 FIG. 4 shows one of the cutting device 1 of FIG Fig. 1 removed ultrasonic transducer 25, which on the one hand with a connection part 21; 22 of the cutting tool 2 and, on the other hand, is connected to a bearing block 29, shown with a quarter cut, which is held on both sides by drivers 118, 128. The drivers 118, 128 are supported by a guide shaft 1181; 1281 pierce, which protrudes beyond the drivers 118, 128 on both sides. the both end pieces of the guide shaft 1181; 1281 are with the guide carriage 119; 129 connected. Also shown are the guide collars 1121, 1221 which engage in one another at the transfer position T1, T2 and form a transfer channel TC. The bearing block 29, which has a bearing channel for receiving the guide shaft 1181, 1281, can be designed as desired and hold any auxiliary devices. For example, the tool motors 211, 221 of Fig. 5d mounted on such a bearing block 29.

Fig. 9 FIG. 1 shows the cutting device 1 of FIG Fig. 1 in a further preferred embodiment and a tool drive 3, which comprises a power transmission device 310 with a drive belt 310. The function of the control unit 5 has been described above.

Fig. 10 FIG. 1 shows the cutting device 1 of FIG Fig. 1 with one of the guide units 1 according to Figures 1 - 9 , in the present case with only one guide unit 1A and with a conveyor device 4 with at least one tubular feed body 42A, which is preferably funnel-shaped or comprises a funnel-shaped element. The feed body 42A can have a tube with a round, for example elliptical, oval or circular, or a polygonal, for example rectangular, square or triangular cross section. The process material P is conveyed through the feed body 42A, for example, by means of an extendable ram or piston.

Optionally, two or more feed bodies 42A, 42B are provided, which can be exchanged by means of a changing device 45 or, with their outlet opening, can be displaced alternately in front of the cutting tool 2. For example, the feed bodies 42A, 42B are slidably mounted on rails 46.
