Definitions

  • the invention relates to a device for cutting a process material, in particular of foods such as meat, cheese, vegetables, bread or pasta.
  • cutting devices e.g. Provided devices with rotating round cutting discs, which are performed at high clock rates against the products to perform the necessary cuts.
  • Such devices are expensive to manufacture, in operation and in maintenance. Due to the rotation of the cutting discs, which have to be reground on a regular basis, a massive effect on the process material takes place, so that particles are released and thrown away, resulting in contamination of the device.
  • the cutting discs and the parameters for their operation are each adapted to the product to be processed, whereby the application is limited or an individual control is provided. If, for example, soft bread is to be cut, then high speeds are required so that it is not compressed when applying a cut. However, if products with different properties are to be processed at the same time, an individual adaptation is hardly possible.
  • cutting devices with rotating cutting disks together with the drive devices take up a great deal of space, so that with regard to the means used, including the required premises, a low efficiency results.
  • special requirements for the cutting unit result in products with large dimensions. If necessary, the cutting disc must be guided along a path to perform the desired cut in the required length.
  • a cutting device in which a knife is connected via a coupling element and an energy converter with an ultrasonic generator. The knife is held on both sides and is moved upwards and downwards perpendicular to its orientation in order to cut a process material.
  • This advantageous cutting device with the associated drive device is designed relatively complex and still takes a relatively large amount of space.
  • the Drive device by means of the knife in two directions, to move up and down, requires a relatively high control effort. If particularly high clock cycles are to be realized, the demands placed on the drive and control device increase disproportionately. Note also the energy requirements of these devices, especially when high clock cycles are realized. It should also be noted that the cutting tools can not perform any cutting work during the return movement, which is why only 50% of the cutting cycle can be used.
  • a device for cutting food with ultrasound-excited cutting tools which are pivotable, thus horizontally and vertically adjustable to Schneidgut.
  • the transport and cutting of the material to be cut takes place on both sides of the stationary held cutting tool.
  • This device thus uses the advantageous properties of ultrasonically excited cutting tools and leads them to the cut material.
  • the kinetic energy required for the cutting process thus takes place by the supplied cutting material and not by the tilted in a desired position and held stationary there cutting tool.
  • the throughput of the material to be cut is thus limited. Furthermore, unsatisfactory cutting results can occur, especially at high feed rates of the material to be cut.
  • a device for cutting cakes which holds an ultrasonically excited knife above a conveyor belt.
  • the knife is slidable and rotatable and can be lowered in a selected rotational position on the conveyor to make a cake in Split cake segments.
  • This cutting device is therefore geared to a specific application and requires a suitably designed storage and drive device, which takes up much space due to the possible movements of the knife.
  • This device differs from the device of EP1935592A1 in that the cutting tool can not only be turned into a desired position, but can also be guided against the material to be cut in order to divide it.
  • the US6070509A discloses a device for cutting food products with a positioning device for an ultrasonic knife, which is mounted above a conveyor belt and can be guided against the conveyed on the conveyor belt food products.
  • the positioning device makes it possible to move the knife along two axes in the cutting positions.
  • the US2006260451A1 discloses another apparatus for cutting food products with a robotic arm that can selectively align an ultrasonic knife along one of several axes and cut a food product along a straight or curved line.
  • the present invention is therefore based on the object to provide an improved device for cutting process material, in particular food.
  • a cutting device is to be specified, which can be of compact construction and takes up only a small amount of space, so that it can be advantageously integrated into any production processes and production processes.
  • the cutting device should be able to be operated with high efficiency and in particular in the range of high clock cycles with low power consumption.
  • the cutting device should be simple and can be maintained with little effort. On the blade or on the blade of the cutting device no signs of wear should occur even after prolonged use.
  • the process material should be able to be cut with high precision and high clock rates.
  • the cut products, in particular food slices should have flat cut surfaces and uniform thicknesses. The precision should be maintained even when the strength properties of the supplied food or parallel supplied food units changes or when the cuttings are conveyed at a higher speed.
  • the inventive cutting device should also be used advantageously in conjunction with extruders, which deliver a process material, in particular food, which is to be cut into individual parts.
  • the device which serves to cut a process material or cutting material, in particular a food, comprises at least one cutting tool in the form of a blade which is connected on the one hand to a drive device and on the other hand via a coupling element and an energy converter with an ultrasonic generator.
  • the coupling element and the energy converter are kept rotatable so that the blade which can be acted upon by ultrasound energy is rotatable.
  • the coupling of the ultrasonic energy allows the blade to cut the process material with little energy and virtually no effort.
  • the surface waves occurring on the blade separate the structure of the process material before the blade penetrates deeper into the process material. This allows a rapid penetration of the blade, without deformations occur in the process material.
  • the energy required for the division of the process material is therefore made available exclusively by the cutting device, which is why the process material can be conveyed at high speed.
  • the cut is therefore not made by the movement of the process material relative to a stationary blade, but by the movement of the blade of the inventive cutting device relative to the fully or largely stationary process material.
  • the rotation speed of the blade can be selected in a wide range. In particular, for hard products, a rotational speed can be selected which is lower than the rotational speed of the round cutting discs. For softer products, the rotational speed can be chosen in a much higher range. Deep rotational speeds for hard or viscous products are for example in the range of 1-10 Rotations or 1-10 rotations by 360 ° of the blade per minute. High speeds of rotation for soft or soft liquids are for example in the range of a few hundred or a thousand revolutions per minute.
  • the process material can therefore be processed or cut by the blade according to the properties of the process material.
  • Process material can be passed through the area where the blade is rotated. It is therefore not necessary to guide the blade back and forth.
  • the rotatable blade device is typically stationary and therefore simple in construction and requires less space.
  • the blade instead of moving the blade back and forth to cut the process material, it is rotated in a plane that is perpendicular to the drive axis. Therefore, the blade does not have to be braked and accelerated again, but can be continuously rotated in the same direction without energy losses.
  • the control of the working cycles of the knife can thus be done in a simple manner by controlling a drive motor.
  • the maximum operating frequency is therefore not determined by the drive device, but by the maximum cutting speed with which the blade can be passed through the process material. Since this maximum cutting speed is very high in the inventive application of ultrasonic energy, very high clock cycles can be achieved.
  • the application of ultrasonic energy for example, with an operating frequency of 35 kHz gives the inventively designed knife particularly advantageous properties.
  • the ultrasonic energy is preferably over the large Side surfaces of the blade back transversely to the cutting direction of the knife coupled into the blade.
  • a blade facing the end of the coupling element is preferably perpendicular to the blade.
  • elastic waves result within and / or on the surface of the blade, which intensify towards the cutting edge.
  • Suitable waves result in a curved or curved configuration of the coupling element, which is preferably designed U-shaped.
  • the blade can only be provided with a cutting edge on one side or on opposite sides.
  • the cutting device is designed such that the blade can be rotated in both directions. This doubles the amount of time a blade can be operated before it has to be re-ground. Also possible is the use of two or more blades, which are held by means of separate or interconnected coupling elements.
  • the coupling element is preferably held by a drive shaft or rotor shaft.
  • the drive shaft facing end portion of the coupling element is aligned coaxially with the drive shaft.
  • the coupling element is integrated in the drive shaft.
  • the drive shaft may be formed as a hollow shaft having an opening which is suitable for receiving the coupling element.
  • the coupling element may be fixed within the hollow shaft by sliding blocks, adhesive or the like.
  • the drive shaft is mounted on at least one bearing element and connected directly or indirectly via drive elements, such as gears and timing belt, with a drive unit, such as an electric motor.
  • the drive shaft further carries the energy converter or the energy converter and the ultrasonic generator.
  • the energy converter connected to the coupling element for example a piezoelectric element, is rotated together with the drive shaft.
  • Only in preferred embodiments of the ultrasonic generator is also connected to the drive shaft and kept rotatable.
  • Energy and / or control signals can be fed to the energy converter and / or the ultrasound generator or a control unit connected thereto and likewise rotatably held via an electrical coupling unit.
  • Control signals can also be transmitted via a radio interface, for example according to the Bluetooth method. Also possible is the optical transmission of control signals.
  • electrical energy and / or electrical control signals are transmitted by galvanic coupling or by inductive coupling.
  • the galvanic coupling takes place for example via rotating contact rings, which are connected to the drive shaft, and stationary sliding contacts.
  • the inductive coupling takes place by means of coils, via which alternating voltages are inductively transferable.
