[0083] FIG. 10 the cutting device 1 of FIG. 1 with a further exemplarily shown conveyor device 4.

[0084] FIG. 1 shows an inventive cutting device 100 in a preferred embodiment with a guiding device 1, which comprises two guiding units 1A, 1B, which serve to guide a cutting tool 2, which is held between the guiding units 1A, 1B and can be guided in vertical alignment along a guide loop. The two guiding units 1A, 1B, which are preferably mirror-inverted and aligned frontally with respect to each other, each comprise an upper guiding module 11A; 11B and a lower guiding module 12A; 12B. The guiding modules 11A, 11B; 12A, 12B are preferably identical and may be rotated by 180° in relation to each other.

[0085] Each of the guiding modules 11A; 11B; 12A; 12B comprises a first guiding wheel 111; 121 and a second guiding wheel 112; 122, which are rotatably held in pairs by guiding plates 115; 125 (see FIG. 2a). The guiding wheels 111, 112; 121, 122 are formed as toothed wheels and engage in each other with their toothing. The guiding plate 115 of the upper guiding module 11A of the first guiding unit LA has been cut vertically in the middle.

[0086] From each pair of cooperating guiding wheels 111, 121; 112, 122 a follower 118; 128 (see FIG. 2a) is held and circulated along the guiding loop. A guiding slide 119; 129 (see for example FIG. 3c) is provided coaxially aligned with each follower 118; 128. The end pieces of the followers 118, 128 which are facing the guiding plates 115, 125, and the guiding slides 119, 129 are guided in guiding channels, which are arranged in each of the related guiding plates 115; 125 and run parallel to the guiding loop.

[0087] Below it is described and shown that each follower 118; 128 is alternately circulated by the related pair of guiding wheels 111, 121; 112, 122 along their periphery, which is why the guideway comprises the shape of figure eight. The cutting tool 2 is thus cyclically guided along a figure-of-eight path comprising a crossing point or transition point T1; T2 (see FIG. 2a).

[0088] The guiding device 1 comprises a mounting structure 10 connecting the two guiding units 1A, 1B and their guiding modules 11A, 11B, 12A, 12B. The two guiding units 1A, 1B comprise associated structural units 10A, 10B which are interconnected by connecting elements 10C.

[0089] The guiding wheels 111, 121; 112, 122 and the cutting tool 2 are driven by means of a tool drive 3, which comprises a drive motor 30, which drives the guiding wheels 112; 122 (see FIG. 2a) via a force transmission device 31, which drives the associated further guiding wheel 111; 121 via their toothing. The force transmission device 31 comprises gear wheels which are rotatably held by gear wheel shafts and which are positively coupled on the one hand to the drive motor 30 and on the other hand to the guiding wheels 112, 122. The power transmission from the drive motor 30 to the guiding wheels 112, 122 can also be effected by drive belts, preferably a toothed belt and possibly toothed wheels, as shown in FIG. 9. It is also possible to drive the guiding wheels 111, 121; 112, 122 by individually assigned drive motors that operate synchronously.

[0090] The guiding device 1 with the cutting tool 2 can be integrated in any devices and processes in order to cut a process material P. FIG. 1 shows an example of a conveyor device 4 with a pushing device 41, by means of which a process material P can preferably be pushed step by step against the cutting tool 2. The pushing device 41 comprises a conveyor motor 40, by means of which a feed slide 411 can preferably be moved stepwise along a feed track 412. With the feed slide 411, pushing tools 413 are displaceable against the process material P. The process material P is guided by side plates 421 and is displaced against the cutting tool 2, preferably step by step, via a feed plate 42 in accordance with the cutting cycles.

[0091] The cutting device 100 preferably comprises a control unit 5, by means of which the movement of the cutting tool 2 and the feeding tools 413 can be controlled. FIG. 9 shows that the position of the cutting tool 2 is detected by at least one sensor 50 and reported to the control unit 5. Subsequently, the control unit 5 sends corresponding control signals 53, 54 to the drive motor 30 and the conveyor motor 40 to control the feed of the process material P according to the movements of the cutting tool 2. After performing a cutting cycle and before starting the next cutting cycle, the process material P can be advanced by a distance corresponding to the set cutting thickness. The control unit 5 can be, for example, a conventional personal computer.

[0092] In preferred embodiments, the control unit 5 also comprises 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, for example, to piezo elements which convert the electrical oscillations into mechanical vibrations.

[0093] 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. 2a) provided at both ends of the cutting tool 2 are held and guided on both sides in this embodiment. The guiding device 1 can also be designed in such a way that the connecting parts 21, 22 are only guided on one side in a guiding module 11A; 12A. Furthermore, it can be provided that only one of the connecting parts 21; 22 of the cutting tool 2 is guided on one side through one or on both sides through two guiding modules 11A, 11B; 12A, 12B lying opposite each other (see FIG. 5c) and the other connecting part 22; 21 follows in any path. The cutting device 100 can therefore be constructed and extended according to the needs of the user.

[0094] FIG. 2a shows the cutting device 100 of FIG. 1 with a symbolically shown, optionally wire-shaped cutting tool 2 and the guiding device 1 with the first guiding unit 1A from the viewpoint of the second guiding unit 1B, which is, however, only optionally provided.

[0095] The end pieces or connecting parts 21, 22 of the cutting tool 2 are each connected with a follower 118, 128, which can be circulated in a figure-of-eight path alternately along the periphery of the two mutually corresponding guiding wheels 111, 112; 121, 122, which are held by means of bearing devices 7. The bearing devices 7 comprise bearing shafts 71 which are held in central bearing openings 70 of the guiding wheels 111, 112; 121, 122.

[0096] The guiding wheels 111, 112; 121, 122 [0097] a) are peripherally adjacent to each other at transfer positions T1, T2; [0098] b) are designed as toothed wheels and engage in one another with toothing; [0099] c) each peripherally comprise a receiving opening 1110, 1120; 1210, 1220 which is open at least approximately radially outwards and serves to receive a follower 118; 119; [0100] d) are rotatable by the tool drive 3 with the same angular velocity in opposite directions; [0101] e) are arranged in such a way that their receiving openings 1110, 1120; 1210, 1220, as shown in FIG. 2a, lie opposite each other after each revolution at the related transfer position T1; T2, so that the followers 118; 119 can be transferred alternately from one receiving opening 1110, 1120; 1210, 1220 to the other at the transfer position T1; T2 and can be guided further alternately along the periphery of the first guiding wheel 111; 121 or of the second guiding wheel 112; 122.

[0102] In FIG. 2a, the followers 118, 128, which have just passed around the first guiding wheels 111, 121, are held in the receiving openings 1110, 1120 of the first guiding wheels 111, 121 and are subsequently transferred by centrifugal forces or guided by force into the receiving openings 1120, 1220 of the second guiding wheels 112, 122 and subsequently pass around the second guiding wheels 112, 122. Even before reaching the transfer positions T1, T2, the followers 118, 128 can move outwards so that they are thrown into the adjacent receiving openings 1120, 1220.

[0103] FIG. 2b shows the cutting device 100 of FIG. 2a after the transfer of the follower 118, 128 to the second guiding wheels 112, 122 and a further rotation of the coupled guiding wheels 111, 112; 121, 122 by 90° in opposite directions, after which the cutting tool 2 was moved one 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 guiding wheels 112, 122, but also upwards.

[0104] It is therefore visible that the connecting parts 21, 22 of the cutting tool are deflected downwards and upwards twice during a cycle according to the diameter of the guiding wheels 111, 112; 121, 122 and moved back and forth according to twice the diameter of the guiding wheels 111, 112; 121, 122. The cutting tool 2 thus performs a tangential movement relative to the process material while it is guided through the process material. The process material is thus cut with high precision without being compressed.

[0105] FIG. 3a shows the cutting device 100 of FIG. 1 from the front side with the guiding device 1 with the two guiding units 1A, 1B, between which the cutting tool 2 is held circulatable within the loop. The guiding wheels 111, 112; 121, 122 are mounted in pairs in upper and lower guiding plates 115, 125.

[0106] The process material (not shown) is conveyed via the feed plate 42 to the cutting tool 2, which is cyclically guided back and forth in front of the feed plate 42, preferably corresponding to the entire width of the feed plate 42.

[0107] FIG. 3b shows the cutting device 100 of FIG. 3a after removal of the upper and lower guiding plates 115, 125 from the second guiding unit 1B. The guiding slides 119, 129 are exposed at the front and are guided in guide channels provided in the removed guiding plates 115, 125.

[0108] FIG. 3c shows the cutting device 100 of FIG. 3b without the optionally provided second guiding unit 1B, looking at the cutting tool 2 whose connecting parts 21, 22 are held by optionally provided ultrasonic transducers 25. It should be noted that the guiding device 1 can also be realised in this configuration, i.e. only with the first guiding unit 1A. The double-sided guiding is preferred when process material is cut with high force. The force required to cut the process material, on the other hand, can be reduced by applying ultrasonic energy to the cutting tool 2.

[0109] It is shown that the followers 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 with a connecting part 21, 22 of the cutting tool 2. The connecting parts 21, 22 are connected, for example, with a metal cylinder, which is braced inside the ultrasonic transducer 25 with piezo elements. 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 connecting parts 21, 22.

[0110] FIG. 3d shows the cutting device 100 of FIG. 3c without the ultrasonic transducer 25 looking at the followers 118, 128 in the position of FIG. 2a, in which they are transferred from the first guiding wheels 111, 121 to the second guiding wheels 112, 122. Any cutting tools 2 can be connected to the followers 118, 128. Preferably, the exemplarily shown cutting tool 2 is used, which comprises 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 from right to left.

[0111] FIG. 3e shows the cutting device 100 of FIG. 3d without the guiding wheels 111, 112; 121, 122 looking at optionally provided guiding channels B11, B12 provided in the guiding plates 115, 125. The followers 118, 128 and the guiding slides 119, 129 are guided in different channel segments of the guiding channels B11, B12. By means of the guiding channels B11, B12 the followers 118, 128 can be positively guided. The guiding slide 119, 121 ensure that the cutting tool 2 is always guided in the correct direction at the transition positions T1, T2.

[0112] FIG. 4 shows the cutting device 100 of FIG. 1 with a view from above between the two guiding units 1A, 1B, between which the cutting tool 2 is held. The guiding plate 115 of the upper guiding module 11B of the second guiding unit 1B has been cut horizontally at half height along the cutting line A-A shown in FIG. 3a. In the cut guiding plate 115, parts of the guiding channel B11 are exposed. In the area of the transition position T1, the follower 118 and the guiding slide 119 held in the guiding channel B11 are shown. Furthermore, the inserted bearing devices 7 are visible.

[0113] FIG. 5a shows the cutting device 100 of FIG. 1 with the moving elements the two guiding units 1A, 1B of the guiding device 1 and the cutting tool 2 in the position of FIG. 2a. The cutting tool 2 is held between the first and second guide wheels 111, 121; 112, 122 of the first and second guiding unit 1A, 1B by followers 118, 128 of the two guiding units 1A, 1B.

[0114] FIG. 5b shows the cutting device 100 of FIG. 5a with the moving elements of the first guiding unit 1A of the guiding device 1. As mentioned, the guiding device 1 can also be operated in this configuration. It is shown that guiding shafts 1181, 1281 protrude from the followers 118, 128. The followers 118, 119 of the two guiding units 1A, 1B are hollow cylindrical and rotatably held on both sides by the guiding shafts 1181, 1281.

[0115] FIG. 5b shows further that the first guiding wheel 111; 121 is provided with a first guiding collar 1111; 1211, which projects beyond the first guiding wheel 111; 121 and engages at the transfer position T1, T2 in a second guiding collar 1121; 1221, which is attached to the second guiding wheel 112, 122. The guiding collars 1111, 1211, 1121, 1122 are V-shaped and enclose with two guiding arms the associated receiving opening 1110, 1120, 1210, 1220 of the related guiding wheel 111, 112, 121, 122. Through the mutual engagement of the guiding collars 1111, 1211; 1121, 1122, a transfer channel TC is formed at the transfer position T1, T2, through which the followers 118, 128 can pass from one to the other receiving opening 1110, 1210; 1120, 1220 in a controlled manner. The guiding arms of the guiding collar 1111, 1211, 1121, 1122 can be shaped as required, so that, for example, a gradient results, along which the followers 118, 128 can roll or slide in accordance with the centrifugal forces and gravitational forces acting on them.

[0116] FIG. 5c shows the cutting device 100 of FIG. 1 with the first guiding unit 1A, optionally with the not shown second guiding unit 1B in a preferred embodiment, in which only the first connecting part 21 of the cutting tool 2 is circulated around the guiding wheels 111, 112 of the upper guiding module 11 and the second connecting part 22 in the lower guiding module 12A is cyclically guided back and forth in a straight or curved, vertical or inclined guiding channel B12. In principle, a self-contained second guiding channel B12, for example running along a circle or an ellipse, can also be provided. In the example shown, the follower 128 and the optionally provided guiding slide are guided vertically upwards and downwards.

[0117] FIG. 5d shows the cutting device 100 of FIG. 5b with the moving elements of the guiding unit 1A of the guiding device 1 with a wire-shaped cutting tool 2. The cutting tool 2 is mounted rotatably about its longitudinal axis and is preferably connected to and driven by electric tool motors 211, 221 at both connecting parts 21, 22.

[0118] FIG. 6 shows an exploded view of the guiding device 1 with the first guiding unit 1A and the tool unit 2 with the ultrasonic transducers 25 of FIG. 3c.

[0119] FIG. 7a shows the upper guiding module 11A of FIG. 3d without the first guiding wheel 111 with the follower 118 at the transfer point T1 between the first and second guiding wheel 111, 112.

[0120] FIG. 7b shows the upper guiding module 11A with a vertical section along the intersection line B-B of FIG. 6 through the guiding plate 115 at the position of the follower 118. It is shown that the guiding slide 119 is correctly aligned and guides the follower 118 correctly over the intersection of the guiding channel B11.

[0121] The guiding channel B11 comprises three channel segments B1, B2 and B3. In the middle channel segment B1 an end piece of the follower 118 is guided. In the lowest channel segment B2 the guiding slide 119 is aligned and guided accordingly. In the uppermost channel segment B3 the guiding wheels 111, 112 are countersunk. This ensures that the follower 118, 128 can only detach from the guiding wheels 111, 112; 121, 122 at the transfer positions T1, T2.

[0122] At the transfer point T1, the middle channel segment B1 is somewhat wider, which is why the guiding here is essentially done by the guiding slide 119.

[0123] FIG. 7c shows the upper guiding module 11A of FIG. 3d without the first guiding wheel 111 with the follower 118 moved further by a quarter turn of the second guiding wheel 112. Furthermore, the follower 118′ is shown at a further position within the part of the guiding channel B11 in the area of the first guiding wheel 111. The follower 118 has been moved in a clockwise circular path around the second guiding wheel 112 and inserted from below into the circular path around the first guiding wheel 111.

[0124] FIG. 7d shows the upper guiding module 11A of FIG. 7c with a vertical section along the section line B-B of FIG. 6 through the guiding plate 115 at the position of the follower 118, which was reached after the quarter turn of the second guiding wheel 112. The follower 118 is guided here in the middle channel segment B2 with little play. The guiding slide 119 is horizontally aligned in this position in the lowest channel segment B1.

[0125] FIG. 8 shows an ultrasonic transducer 25 taken from the cutting device 1 of FIG. 1, which is connected on the one hand to a connecting part 21; 22 of the cutting tool 2 and on the other hand to a bearing block 29 shown with a quarter section, which is held on both sides by followers 118, 128.

[0126] The followers 118, 128 are penetrated by a guiding shaft 1181; 1281, which projects beyond the followers 118, 128 on both sides. The two end pieces of the guiding shaft 1181; 1281 are connected to the guiding slides 119; 129. Also shown are the guiding collars 1121, 1221 which engage with each other at the transfer position T1, T2 and form a transfer channel TC. The bearing block 29, which comprises a bearing channel for receiving the guiding shaft 1181, 1281, can be of any shape and can hold any auxiliary devices. For example, the tool motors 211, 221 of FIG. 5d are mounted on such a bearing block 29.

[0127] FIG. 9 shows the cutting device 1 of FIG. 1 in a further preferred embodiment and a tool drive 3, which comprises a force transmission device 310 with a drive belts 310. The function of the control unit 5 has been described above.

[0128] FIG. 10 shows the cutting device 1 of FIG. 1 with one of the guiding units 1 according to the FIGS. 1-9, in this case with only one guiding unit 1A and with a conveyor device 4 with at least one tubular feeding body 42A, which is preferably funnel-shaped or comprises a funnel-shaped element. The feeding body 42A can comprise 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 feeding body 42A, for example by means of an extendable plunger or piston.

[0129] Optionally, two or more feeding bodies 42A, 42B are provided, which can be exchanged by means of a changeover device 45, or can be moved with their outlet opening alternately in front of the cutting tool 2. For example, the feeding bodies 42A, 42B are slidably mounted on rails 46.
