It is an object of the invention to provide an improved cutting device.

This object is achieved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

According to claim 1, a cutting device for cutting food clippings is provided in helical (helical / helical) strips. As for clippings or cutting food vegetables and fruits can be used, such as potatoes, radish, cucumbers, carrots, apples, etc. The cutting device has a base body (base frame), on which a holding device and a bearing plate are mounted. The holding device has a retaining element and the abutment plate has an outlet opening for cut foods (strips) or cut clippings on. A blade for cutting the cuttings is integrally formed with the abutment plate or, alternatively, the abutment plate is adapted to receive a (preferably interchangeable or replaceable) blade. A drive device with a motor is designed to drive the holding element in rotation about a main axis of the cutting device. The major axis is preferably oriented vertically or substantially vertically. Alternatively, the major axis is oriented at an angle to the vertical, in particular, the major axis is oriented horizontally or substantially horizontally.

In the use of the cutter, clippings (e.g., a potato) are picked up and held (clamped) between the abutment surface of the abutment plate and the holding member. By means of a feed device of the cutting device, the holding element and / or the abutment plate is displaced / moved along the main axis. For example, the feed device comprises a manual drive, a gravity-actuated drive or a drive operated by gravity, an electric drive, a pneumatic drive and / or a hydraulic drive for moving between the start position (S) and the end position (E). The holding element is movable by means of the feed device between a starting position in which the cut material can be inserted / inserted into the cutting device, and an end position in which a cutting operation is completed. Alternatively or additionally, the contact plate can be moved by means of the feed device. In an embodiment, the feed device has a lever arrangement with a manually operable lever for moving between the start position and the end position.

During the cutting process, the cut material is delivered by means of the feed device of a arranged on the contact plate blade. By moving the cutting stock held in the cutter along the major axis and simultaneously rotating about the major axis by rotating the holding member, the cut material passes over the blade in the abutment plate and is cut into helical strips by the blade.

The cutting device has a counter-element, which is arranged on the contact plate (contact surface) and / or is formed integrally with the contact plate. The counter-cam is aligned axially with respect to the main axis and arranged in the direction of the main axis opposite to the holding element, so that the cut material can be held between the holding element and the counter-element. By means of the counterorn on the Anlageplatte is the food clippings before and during a cutting process secured against slipping sideways.

Preferably, the holding element has a receiving opening for the counter-element, wherein the counter-element is at least partially positioned in the receiving opening in the / an end position. The counter-element can engage in the end opening in the receiving opening, so that both serve as a stop for the end position and in the end position, the holding element by means of the counter-member spaced from the contact plate and / or the blade (or blade of the blade) is held. Preferably, however, in the end position, a clearance is provided between the counter-tooth and the receiving opening, so that no abrasion occurs.

Preferably, the feed device has an end stop element, so that in the end position the counter-element is spaced from the inner surface of the receiving opening and / or the holding element (or its projecting pins) are held at a distance from the abutment plate and / or the blade. The end stop member acts as a spacer between the retainer and abutment plate at the end of a cutting operation (or in the end position), thereby preventing damage to the blade and / or the abutment plate by contact of the (rotating) retainer with the blade / plate. For example, by means of the end stop element, a distance between the holding element and the abutment plate / blade of 5 mm to 15 mm is provided, alternatively from 5 mm to 10 mm.

In an embodiment, the abutment plate or a contact surface of the abutment plate and / or a cutting edge of a blade mounted on the abutment plate are arranged perpendicularly or substantially perpendicular to the main axis. Alternatively, a cutting edge of the blade is arranged at an angle smaller than 90 ° to the main axis.
Preferably, the abutment surface of the abutment plate has a plurality of concentric circular grooves and / or grooves with respect to the major axis. The concentric grooves reduce the friction of the (rotating) cuttings during a cutting process. In addition, the grooves guide the clippings in the direction of rotation about the major axis.

The abutment plate is preferably mounted on the base body by means of a detachable fixing device, in particular by means of a fixing device that can be released without tools or that can be released manually. That is, the contact plate is detachably mounted on the base body, and in particular without tools from the cutting device can be removed. The support plate can therefore eg for cleaning or maintenance simply from the Cutting device can be removed. For example, the fixing device has two opposite rails which are mounted on the base body. In an embodiment, the rails have grooves into which the contact plate can be inserted.

In an embodiment, the contact plate or the contact surface has a depression or recess for receiving a blade, in particular for the positive reception of a blade. The indentation stabilizes the blade mechanically and additionally helps to position a (exchangeable / replaceable) blade. Preferably, the recess is formed so that at least one blade back of the blade or the side of the blade, which is opposite to the cutting edge, rests against one side of the recess. The recess thus provides a stop for the blade during attachment of the blade and also prevents slippage of the blade in the rotational / cutting direction during a cutting operation. Preferably, the recess is configured so that a blade is inserted into the recess and then fastened with fastening means, such as a screw. Screws can be fastened. Alternatively, the recess is formed as a pocket, in which a blade can be inserted positively, so that a blade of the blade protrudes from the pocket and the contact surface.

Preferably, a base of the recess on which rests a (fixed) blade at an angle to the contact surface, so that a recorded in the recess blade protrudes at an angle from the contact surface. The bearing plate thus has an inclined recess for the blade. Et al the inclination of the recess determines the cutting angle of the blade and / or the cutting thickness for a clippings. In particular, different cutting thicknesses can be provided by using blades with different blade thicknesses with the same contact plate or recess. The amount of the angle between the base of the recess and the contact surface of the contact plate can be between 10 ° and 20 °, preferably between 10 ° and 15 °, more preferably between 5 ° and 10 °. Alternatively or additionally, the cutting thickness of the crop is determined by the depth of the blade, i. The dimension of the blade from the cutting edge perpendicular to the cutting edge to the back of the blade.

The motor of the drive device is preferably an AC motor, so that the motor can for example be connected directly to the power supply (230 V) or no transformer / power supply is necessary. Preferably, the engine has a transmission, wherein the transmission provides a transmission ratio (= ratio of input speed to output speed) of greater than one or the transmission, a reduction gear is. Thus, the transmission provides a low gear ratio (reduction), so that a higher torque is provided for the cutting device or a cutting operation. Preferably, the engine and the transmission are integrated in block construction

The engine has advantageous (with or without gear) a torque between 1 Nm and 5 Nm, preferably between 1.5 Nm and 4 Nm, more preferably between 2 Nm and 3 Nm. The torque corresponds to the quotient of power and speed. Alternatively, the engine or the engine with gear on the support member has a torque between 1 Nm and 5 Nm, preferably between 1.5 Nm and 4 Nm, more preferably between 2 Nm and 3 Nm.

In an embodiment, the cutting device has at least one limit switch, wherein by means of the at least one limit switch, the drive device and / or the feed device on reaching the end position, the start position and / or a rest position of the holding element is switched off. The one or more limit switches thus provide a safe shutdown of the motor of the drive device and additionally or alternatively the feed device, so that the risk of injury to users is reduced.

The cutting device preferably has a control unit, wherein the rotational speed of the motor is controllable by means of a control element connected to the control unit. Preferably, the rotational speed is infinitely variable and / or the motor has a soft start, in particular a controlled by the control unit soft start.

By means of the control element or the speed controller or adjusting element, the engine speed can be adapted to the consistency of the crop. For example, with soft vegetables (even older potatoes, for example), there is a risk that the vegetables will crack at too high rotational speeds and thus no continuous / uninterrupted vegetable spirals can be cut. The control element or speed controller may be e.g. be operable with the foot or be designed as a footswitch / pedal, so that a user has both hands free when using the cutting device. Alternatively, a (hand) controller can be provided.

A soft-start motor prevents excessive torque or acceleration when the motor starts up, causing the (clamped) Cuttings could tear. In addition, it is ensured that in the initial phase of a cutting process, the clippings are only slowly rotated until a flat cut surface has formed on the clippings, which rests securely on the contact plate. The motor is preferably equipped with soft start and with a speed controller.

The cutting device preferably has a control element connected to the switching element for switching on / off of the motor, in particular designed as a pedal switching element. Preferably, in each case a first switching element for switching on and a second switching element for switching off the motor, particularly preferably an additional emergency stop switch.

Preferably, the cutting device has a console for mounting the motor or the motor with gear, wherein the console is mounted on the base body via a linear guide and by means of the feed device is movable parallel to the main axis. Advantageously, the holding element or the holding device and / or the feed device are also mounted on the movable console. Particularly preferably, the motor, the gear, the holding device, the feed device and / or the console are at least partially enclosed by a housing of the cutting device, so that a hygienic processing / cutting of food is possible.

Preferably, the above-described cutting device has a safety and splash protection unit mounted on the main body with at least one front wall, a rear wall and the front and rear wall connecting side walls, wherein the (front / rear / side) walls a working area between the support plate and laterally surround the holding element or at least partially enclose the side, and wherein the splash guard unit in particular has a passage opening for the holding element or the walls enclose a passage opening. The working area is the space that lies between the contact surface of the contact plate and the start position / end position of the holding element or the space in which, when used, cut material is clamped between the contact plate and the holding element. The front / front wall faces the operating personnel and the rear / rear wall faces the front / front wall. The safety and splash guard protects a user from splashes or loose clippings, and additionally prevents a user from touching the sharp or rotating parts of the cutter during the cutting process.

The splash guard unit can at least partially surround the bearing plate and / or the rails laterally, in particular enclosing in a form-fitting manner. Thus, the splash guard unit encloses the area or the plane in which the cutting process takes place and can thus optimally protect / shield the environment from unwanted spatters or loose clippings.
Preferably, the splash guard unit is releasably attached to the base body, attached to the contact plate and / or on the rails, in particular releasably secured without tools. For example, the splash guard unit may be designed so that it can be plugged onto the contact plate. By this configuration, the cleaning of the splash guard unit is facilitated, for example, the (removed) splash guard can be cleaned in a dishwasher.

The splash guard unit preferably has at least two support elements which are mounted and / or rest on the contact plate and / or on the rails when the splash guard unit is used.

Preferably, the splash guard unit is integrally formed, and / or the splash guard unit is at least partially made of plastic, in particular a transparent plastic, or metal, in particular stainless steel formed. More preferably, the splash guard unit is formed of easily cleaned materials, such as e.g. PMMA or acrylic glass, which can also be cleaned in a dishwasher.

Preferably, at least the side walls of the splash guard unit taper in the direction of the main axis from the contact plate to the retaining element, so that the cross-section of one or the through-opening of the splash guard unit decreases along the main axis in the direction of the retaining element. As a result of this configuration, an overhead opening or opening pointing toward the holding element is reduced, so that the splash guard unit better shields or protects the environment from splashes.

According to a preferred embodiment, a blade set is provided for a cutting device as described above, wherein the blade set has at least two blades with different blade thicknesses. The blade of the blade is the part that carries the edge of the blade.

Fig. 1 shows a schematic not to scale side view of a cutting device 2a for cutting foods such as fruits and vegetables, such as potatoes, radish, apples, etc. in helical strips according to a first embodiment.

The cutting device 2a has a base body 4 or a base frame on which a bearing plate 14, a holding device 6 with a holding element 8 and a drive device 10 with a motor 12 are mounted. By means of the drive device 10, the holding element 8 can be driven to rotate about a main axis A. So that the cut material 46 is held securely during a cutting operation by means of the holding element 8, the holding element 8 has a plurality of mandrels 52 which, when used, cut into a cut material 46.

The drive device 10 with the motor 12 and the holding device 6 are mounted on a console (not shown). The console is mounted on the base body 4 by means of a feed device 22a and a linear guide 44 movable parallel to the main axis A. In the in Fig. 1 illustrated embodiment, the feed device 22a an electric drive (not shown) and is also mounted on the console. By means of the feed device 22a are the console or the Retaining element 8 along the main axis A movable and a food to be cut or cut 46 ( Fig. 2a ) can be clamped and held between the support member 8 and the abutment plate 14. Preferably, the motor 12 of the drive device 10 and / or the feed device 22a are controlled by a control unit 13, wherein the control unit 13 turns on and off the motor and advantageously determines its speed and / or controls the feed and the retraction of the feed device 22a.

Alternatively, the feed device 22a may be a manual drive ( Fig. 2a, 2b ), a pneumatic drive or hydraulic drive to move the console. The drive device 10, the feed device 22a and / or the console are at least partially enclosed by a housing 40 of the cutting device 2a, so that a hygienic processing / cutting of food is possible. At the in Fig. 2a / 2b shown manual drive means of the lever can be sufficient depending on the strength of the cuttings, the weight of the drive and the holding device 8 to lower the holding means gravity, so that the operator for cutting the lever 50 does not have to operate.

As in the plan view and side view of Fig. 3a and 3b and the side sectional views of Fig. 4a-c along the line BB in Fig. 3a shown schematically and not to scale, the abutment plate 14 has an outlet opening 42, via which a blade 18a is fixed with a cutting edge 20a or can be fixed, for example by means of screws 56, 56 '. For the sake of clarity, the blade 18a in the Fig. 1 . 2a, 2b not shown.

The Fig. 2a and 2b show a cutting device 2b according to a second embodiment. The difference to the in Fig. 1 shown and described first embodiment is a manually operated feed device 22b. The manual drive is provided by a lever assembly having a manually operable lever 50. All other elements and features of the above and below with respect to Fig. 1 . Fig. 3a-b and Fig. 4a-c described cutting device 2a according to the elements and features of the cutting device 2b.

The following is based on Fig. 2a and 2b a cutting process for producing helical (food) strips 48 is described by way of example. In Fig. 2a the cutting device 2b is shown in a starting position S, in which the cut material 46 between the holding member 8 and a contact surface 16 of the abutment plate 14 is fixed or is trapped. For this purpose, the holding element 8 is moved by means of the feed device 22b down in the direction of the contact plate 14 / abutment surface 16 until the holding element 8 abuts against the top of the cuttings 46 (start position S). The lever arrangement of the feed device 22b is mounted on the console and the base body 4 accordingly, so that by pulling down the lever 50, the mounted on the linear guide 44 bracket and the support member 8 are also moved down. Subsequently, the drive device 10 is activated, so that the holding element 8 rotates with the cut material 46 about the main axis A. By the simultaneous movement of the holding element 8 along the main axis A in the direction of the contact plate 14, the cut material 46 of the blade 18 a is delivered and in helical strips 48 (FIG. Fig. 2b ) cut, which can be collected in a container 54 below the outlet opening 42.

The lower end of the linear guide 44 is connected to an H-shaped stand 45, which carries the cutting device. Between the front legs of the base of the container 54 can be placed on a work surface, so that even tall containers can be placed.

In the end position E of the cutting device 2b / of the holding element 8, the cutting operation is completed and the drive device 10 can be deactivated again or the motor 12 can be switched off. In the end position E, the path of the console or of the housing 40 is limited by a stop element 58, which is arranged on the linear guide so that between abutment plate 14 and blade 18 a, b and holding element 8 is maintained sufficient distance to a mutual contact or to avoid damage. On the stop element 58, for example, the Endabschalter for the motor 12 and / or the feed device 22 may be provided a. The drive device 10 (and possibly the feed device 22a (if they are as in Fig. 1 shown having an electric drive) can be activated / deactivated, for example by means of a manually operable switch (eg footswitch). Alternatively, the cutting device 2 may have one or more end bearing switches which deactivate the drive device 10 and feed device 22a when the end position E is reached.

As in Fig. 1 . 2a and 2b a counter-tooth 24 is arranged on the contact plate 14 or contact surface 16 which is aligned axially with respect to the main axis A and lies opposite the holding element 8. When using the cutting device 2a, 2b, the counter punch 24 pierces the cut material 46 and fixes it against slipping sideways during a cutting operation.

In addition, concentric circular grooves or grooves 28, 28 'are formed in the contact surface 16 around the counter-tooth 24 or the main axis A, which reduce the friction between the cut material 46 and the contact surface 16 during a cutting operation and at the same time provide an additional guide for the (rotating) Provide clippings 46.

In the in Fig. 1 . 2a and 2b illustrated embodiments, the retaining element 8 has a receiving opening 26 for the counter-24, which protrudes partially into the receiving opening in the end position E. In an embodiment (for example, as an alternative to the end abutment element 58), the counter-element 24 (and the receiving opening 26) is configured such that upon reaching the end position the counter-element 24 abuts the receiving opening 26 and the holding element 8 (in particular the pins 52) is spaced from the abutment plate 14 and stops at the blade 18a. The counter-element 24 thus provides a stop for the retaining element 8, so that damage to the blade 18 a / the bearing plate 14 is prevented by the rotating retaining element 8.

As in Fig. 3a and 3b illustrated the abutment plate 14 can be removably mounted on the base body 4. For this purpose, two opposing rails 30a, 30b and a support 32 are fixed to the base body 4, so that two opposing grooves are provided, into which the contact plate 14 can be inserted. In this way, the abutment plate 14 can be easily removed and replaced without tools, eg to clean the plate 14 and to change the blade 18a.

Fig. 4a-c show a sectional partial view of the contact plate 14 of Fig. 3 along the line BB. In Fig. 4a the abutment plate 14 is shown without inserted blade 18a. The abutment plate 14 has a recess 34 with a base 36 on which a blade of the blade 18a rests, and a perpendicular or substantially perpendicular to the base surface abutment side 38 on which a blade back of the blade 18 abuts a ( Fig. 4b ). The base surface 36 is arranged at an angle α to the contact surface 16 or the base surface 36 is inclined relative to the contact surface 16. As a result, the blade 18a accommodated in the recess 34 is likewise inclined at an angle α to the contact surface 16 (FIG. Fig. 4b ). The distance between the cutting edge 20a of the blade 18a and the abutment surface 16 determines the cutting thickness x of the blade 18a and the thickness (thickness) of the helical strips cut by this blade 18a. By using a blade 18b with a larger blade thickness b '( Fig. 4c ), the distance between the cutting edge 20b and the abutment surface 16 increases at the same time, ie the cutting thickness x 'of the cutting device 2a, 2b increases. Conversely, can be through using the blade 18a of lesser blade thickness b reduces the cutting thickness x. In this way, the cutting thickness x, x 'can be adjusted or a desired cutting thickness x, x' adjusted by simply changing the blade 18a, 18b.

Alternatively or additionally, the cutting thickness x, x 'can be changed by blades 18a, b having different depths T (cf. Fig. 4c ) are used. The greater the depth (distance between cutting edge 20a, b and blade back (abuts eg on stop side 38)), the further the cutting edge projects beyond the length W of the base surface and the greater the cutting thickness x, x '.

Fig. 5a-d show various views of a safety and splash guard unit 60 for the cutting devices 2a, 2b described above. The splash guard unit 60 protects a user from splashes or releasing portions of the cuttings 46 during a cutting operation. In addition, the splash guard unit 60 prevents a user from coming in contact with sharp or rotating parts of the cutter 2a, 2b during a cutting operation.

Fig. 5a 11 shows a perspective view of the splash guard unit 60 having a front wall 62a, a rear wall 62b, and two side walls 64a, 64b connecting the front wall 62a and rear wall 62b. The walls enclose a passage opening 70 of the splash protection unit 60, in which, when using the splash protection unit 60, the working area of the cutting device 2a, 2b is arranged. The working area lies between the bearing plate 14 and the holding element 8, ie in the area in which clippings 46 are clamped and cut.

Fig. 5b shows a top view of the splash guard unit 60, Fig. 5c a sectional front view along the line AA in Fig. 5b, and Fig. 5d a sectional side view along the line BB in Fig. 5c , In Fig. 5c is exemplified the position of the splash guard unit 60 when used on the contact plate 14 with the rails 30a, 30b. The splash protection unit 60 has, along the side walls 64a, 64b, in each case a continuous support element 68a, 68b which, in use, rest on the rails 30a, 30b and thus hold the splash protection unit 60 on the cutting device 2a, 2b. As an alternative to the continuous support elements 68a, 68b, individual (short) support elements (not shown) may be provided, for example one support on each inner corner of the walls of the splash guard unit 60.

The walls of the splash guard unit 60 are designed so that they surround the contact plate 14 and the rails 30a, 30b (positive fit). As a result, lateral slipping of the splash guard unit 60 is prevented. The splash guard unit 60 can simply be plugged onto the contact plate 14 or the cutting device 2a, 2b and removed again for cleaning without tools.

In comparison with the front wall 62a, the side walls 64a, 64b are extended upward and have a shielding surface 66a, 66b which is inclined inwards or towards the axis A. As a result, the cross-section of the passage opening 70 decreases upward (in the direction of the retaining element 8), so that a user is very well protected during a cutting process. In the rear wall 62b, a recess 72 is provided, so that when removing the splash guard unit 60 from the cutting device 2a, 2b, the rear wall 62b does not hang on the holding element 8, so that the splash guard unit 60 is easily removed.

Preferably, the splash guard unit 60 is formed of an easy-to-clean plastic such as acrylic glass, in particular integrally formed. A transparent material for the splash protection unit 60 also ensures that a user has the rotating cut material 46 in view during a cutting process.
