Definitions

  • the invention relates to a cutting device with a cutting tool.
  • a cutting device 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.
  • ultrasonic energy is applied to the metal blade so that the cutting process can be carried out with reduced resistance.
  • 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 of ultrasonic energy is less.
  • 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.
  • the present invention is therefore based on the object of creating an improved cutting device.
  • 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.
  • guide devices and drive devices for the cutting tool should be constructed in a simpler and more cost-effective manner.
  • 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.
  • the first and / or the second guide module has two guide wheels, a) which are each rotatably held by associated storage devices in a guide plane; b) which border one another peripherally at a first transfer position; c) each having an outwardly open receiving opening at the periphery, which is suitable for receiving the first driver; d) which can be rotated in opposite directions by the tool drive at the same angular speed; 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.
  • 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.
  • 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.
  • 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.
  • the second driver is also actively guided in the same way as the first driver.
  • the second guide module also has a first guide wheel and a second guide wheel, a) which are rotatably supported by associated bearing devices; b) which lie peripherally opposite one another at a second transfer position; c) each having an outwardly open receiving opening peripherally which is suitable for receiving the second driver; d) which can be rotated in opposite directions by the tool drive at the same angular speed; 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.
  • the cutting process there is a cutting movement in two directions.
  • the cutting tool always remains aligned parallel and is shifted cyclically upwards and downwards along its longitudinal axis with a first cutting movement.
  • the cutting tool comes with a second cutting movement moved back and forth perpendicular to it.
  • 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.
  • 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.
  • 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.
  • 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.
  • the guide device is preferably equipped with a first guide unit and a second guide unit.
  • the second guide unit is preferably designed to be a mirror image of the first guide unit this is preferably frontally opposite in a parallel guide plane.
  • 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.
  • 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.
  • 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.
  • identical guide wheels can be used, which only need 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.
  • 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.
  • the drivers and the receiving openings of the guide wheels reach the associated transfer positions.
  • the receiving openings are opposed to each other with a slight gradient, if necessary. Due to the moving mass, the drivers at the transfer position try to continue their path in a straight line that 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 preferably carried out Refinements supported by additional guide elements that can be used individually or in combination.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the drivers and / or the guide carriages are guided in guide plates.
  • Each of the guide modules preferably has a guide plate which serves to support the associated 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.
  • 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 directly or indirectly, fixedly or rotatably connected to the driver.
  • the guide carriage is attached to the guide shaft, which protrudes over the driver accordingly.
  • the guide carriage is guided largely straight along the guide track, so that it always passes diagonally through the intersection, which is located at an assigned transfer position. In this way, the guide track is always smoothly and correctly traversed.
  • 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.
  • 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 each connected to a bearing block that holds an ultrasonic transducer, which is in turn connected to the associated connection part in order to deliver ultrasonic energy to the cutting tool.
  • Cutting devices 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 moved forward according to the desired section thickness and for the next one
  • the cutting tool can therefore make a cut twice with each pass through the guideway.
