Definitions
- the invention relates to a slicer, in particular for cutting foodstuffs, with a machine housing and a circuit mounted therein and "driven by an electric motor”.
- the cutting edge of the circular knife is usually largely covered on the circumference and on the end face opposite the knife bearing, and a slide which can be pushed back and forth parallel to the circular knife and is provided with a material to be cut to convey the material to be cut during the cutting process.
- the drive motor is arranged axially parallel to the overlying circular knife bearing and is non-positively connected to this by means of a belt drive designed as a reduction gear.
- DE 32 18 768 AI describes a household cutting machine with a drive block for the separately mounted circular knife, the drive pinion of the drive block in one with the Circular knife engages firmly connected ring gear.
- Drive pinion and ring gear form a reduction gear.
- a disadvantage of the previously known slicing slicers is the relatively large outlay in the maintenance of the drive and the frequency of the necessary maintenance work thereon.
- the bearing elements of the circular knife in particular require maintenance.
- the invention is based on the object of making the slicing machine described above more service-friendly.
- This object is achieved in that the circular knife on its bearing axis by means of a drive motor mounted on the same bearing shaft directly, i.e. is driven without an additional reduction gear.
- the drive motor is preferably a brushless, electronically commutated direct current motor or three-phase motor with an electronic regulator.
- the compact drive / knife unit can be hermetically sealed by attaching additional seals on both sides of the motor flange and towards the rotating circular knife and is therefore suitable for the rough environmental influences even in wet areas.
- the knife area which because of the direct contact with the food to be cut is part of the main contamination area of the machine, is easy to clean due to the advantageous design of the seals and the now possible avoidance of poorly accessible corners.
- the knife cover lying on the cutting material feed side of the circular knife is preferably for cleaning over a Detachable rotary knob and easily removable. This means that all hygiene requirements are met.
- the frictional torque of the drive / knife unit is significantly reduced, the efficiency of the drive is increased and thus the energy consumption is lower.
- the radial load on the rotary bearing elements of the drive / knife unit is reduced by the omission of the gear radial force and thus has a favorable effect on the service life of the bearing elements.
- the running behavior of the machine is improved by the elimination of the gearbox and leads to a reduction in running noise.
- the housing structure of the cutting machine can be designed more optimally. Overall, the space requirement is less and allows a flatter design.
- the known machine design with an inclined knife level and gravity feed for cut material can also be carried out advantageously.
- Short peak loads do not generate a breakdown torque (device blocking), but are compensated for by a short-term higher current consumption of the motor.
- the heating of the machine during operation is also kept very low, and therefore fans or ventilation slots for heat dissipation are not necessary.
- the heat transfer to the sensitive material to be cut via the circular knife and the machine housing in the disc storage area is very low because the total power loss is low due to the low-loss electronic control.
- the adjustment range of the cutting speed by means of the speed setpoint adjuster in adaptation to the different types of food such as sausage, meat, cheese, fish, is approximately between 140 and 300 m / min.
- FIG. 1 is a front view of a slicing machine according to the invention seen from the operating direction
- FIG. 2 shows a front view of a drive / knife unit according to the invention with a partial section through its central axis
- FIG. 3 shows a side view according to FIG. 2 from the direction of the arrow “X”.
- FIG. 1 shows a slicer 1, which comprises a machine housing 2 with a cover 3 which can be detached at a parting plane 34 for mounting and dismounting a complete drive / knife unit 4, in which a driven circular knife 5 is rotatably mounted.
- a stop plate 7 running parallel to the cutting plane of the circular knife 5 is arranged so as to be adjustable to the cutting plane for the known purpose of adjusting the disk thickness.
- a carriage 8 for receiving a material to be cut, not shown, can be pushed back and forth along the circular knife 5, parallel to the cutting plane. The material to be cut is fed to the rotating circular knife 5 lying on the carriage 8 and cut into slices adjacent to the stop plate 7.
- the cutting plane 9 of the circular knife 5 can be perpendicular to the footprint of the cutting machine 1, as shown in FIG. 1, or can be arranged at a certain angle to the vertical (bevel cutter).
- the drive / knife unit 4 is shown in detail in FIG. It is attached to the machine housing 2 by means of a motor foot 10 attached.
- a drive motor 11 and the circular knife 5 are mounted on a common bearing shaft 12.
- the drive motor 11 is constructed in a known manner and, in the present exemplary embodiment, includes a rotor 13 fixedly connected to the bearing shaft 12, a stator 15 connected to the fixed outer jacket 14 of the motor, two end shields 16, 17 with axially secured therein Ball bearings 18, 18 ', which are preferably designed with sealing washers.
- the speed setpoint generator 33 can be designed as a step switch or potentiometer. In a more convenient version of the device, the setpoint can instead be called up by a higher-level controller (CPU) with article data memory, article-specifically.
- CPU higher-level controller
- a flange 19 for fastening the circular knife 5 is formed on the bearing shaft 12.
- the circular knife 5 is enclosed in a ring on its circumference by a knife protection ring 20, with the exception of the cutting area 6.
- the hub 21 of the spoke protection ring-shaped knife guard ring 20 is firmly connected to the end shield 17 of the motor 11.
- An intermediate elastic seal 22 seals the interior of the drive motor 11 and the interior of the machine housing 2 with cover 3 against dirt and moisture.
- On the other side of the hub 21 there is also an elastic lip seal 23, the lip 24 of which resiliently abuts the circular knife 5. On the one hand, it protects against the ingress of dirt and moisture into the mounting of the drive / knife unit 4 and, on the other hand, it makes cleaning this area easier.
- a knife cover 25 is attached with its outer surface flush with the cutting plane 9 of the circular knife 5 and forms the stop for the material to be cut (not shown) while the carriage 8 is moved along the cutting plane 9.
- the knife cover 25 protects the material to be cut and the operator against contact with the rotating circular knife 5.
- the knife cover 25 is detachably and removably attached.
- the attachment takes place via a rotary handle 26 with a threaded bolt 27 fixed therein, which is guided through the bearing shaft 12 of the motor, which is designed as a hollow shaft according to the invention.
- the threaded bolt 27 is enveloped by a further, fixed hollow shaft 28, which is mounted in a bushing 29 to the rotating bearing shaft 12.
- the knife cover 25 is positively fixed against twisting in the hollow shaft 28 by means of a peg-shaped anti-rotation lock 30, axially centered and clamped via the threaded bolt 27.
- the hollow axis 28 with the end shield 16 is axially adjustable by means of a threaded connection.
- the knife cover 25 can thus be adjusted to the cutting plane 9 of the knife 5.
- the setting is fixed by a lock nut 31. This setting is retained when the knife cover 25 is loosened for cleaning.
- An elastic lip seal 32 attached to the lock nut 31 protects the interior of the machine housing 2 and thus also the drive / knife unit 4 against the ingress of dirt and moisture.
