Description

The invention relates to an electrically operated disc cutting machine for cutting slices of, in particular, strand-like material to be cut, preferably food, with a cutting device comprising a circular blade rotating in a cutting plane about a rotation axis perpendicular to the cutting plane and driven by a knife motor, with a carriage having a slide plate in a carriage plane perpendicular to the cutting plane and carries at least one carriage wall which protrudes from the carriage plane, and with a Schneidguthalter having a support for receiving the cutting material to be cut and which is adapted to the cut material at an angle α <90 ° relative to Bring cutting plane to the circular knife.

Such a slicing machine is known from the US-A 2,187,312 ,

Such disk cutting machines allow a diagonal cut of the material to be cut. The material to be cut can be separated at an angle α at an angle of approximately 45 ° to the longitudinal direction of the material to be cut. In the case of a strand-shaped or cylindrical material to be cut, oval disks can thus be cut on such a disk cutting machine, which have a larger area than approximately circular disks.

The material to be cut could in principle be cut obliquely even without Schneidguthalter by the cutting material is placed according to obliquely on the carriage plate or held obliquely. However, this results in very high injury risks for the user of a slicing machine.

In the cited in the above US-A 2,187,312 described slicing machine is designed as an attachment Schneidguthalter with a screw clamp attached to the carriage plate. The support of the Schneidguthalters can be tilted by means of a crank mechanism against the horizontal, so that it forms an obliquely downwardly extending support surface for the cutting material.

The disadvantage of this solution is that the use of the Schneidguthalters described therein is limited to only a few types of disc cutting machines. For example, already For lack of open space often the screw clamp not fixed as intended on the carriage plate.

Object of the invention is in contrast to improve a generic disc cutting machine cost and readily available with technical means available, in particular to provide a reproducible, reliable and versatile applicable, obliquely cutting electrically powered disc cutting machine.

This object is achieved in a technically particularly simple and surprisingly effective manner by a generic electrically operated disc cutting machine, wherein the Schneidguthalter has a fastening device for accurately fitting the Schneidguthalters on the carriage wall, wherein the fastening device is designed so that the Schneidguthalter in a defined, reproducible Position can be fixed relative to the carriage wall.

In order for the Schneidguthalter can be fixed with the required accuracy and reproducibility on the side wall of the disc cutting machine. A certain geometric configuration of the carriage plate is not required. The sliced product holder can essentially be fixed to any existing slicing machine, provided that the sled has a sled wall. Thus, due to the modularity of the disc cutting machine according to the invention, almost any existing disc cutting machine can easily be retrofitted or converted into a disc cutting machine according to the invention. On a more extensive Adjustment of the slicing machine before attaching the Schneidguthalters can thus be dispensed with as a rule.

In a particularly preferred class of embodiments of the fastening device according to the invention, the design thereof can be selected so that a reversible, with respect to the relative position of Schneidguthalter and carriage wall in the operating state reproducible attachment of Schneidguthalters on the carriage wall and a disassembly of the Schneidguthalters is made possible by the carriage wall. Thus, especially in the field of food processing particularly high hygiene requirements can be relatively easily met, as the installation and removal of Schneidguthalters designed particularly easy and reversible. Thus, for example, the uninstalled Schneidguthalter separately from the other disc cutting machine, for example, in a dishwasher, cleaned and / or disinfected, which significantly facilitates compliance with the high hygiene requirements.

In particular, it can be provided in advantageous developments that the fastening device is designed so that it allows attachment of the Schneidguthalters in different, selectable relative positions of Schneidguthalter and carriage wall, so that different angles can be adjusted, under which the cut material obliquely to the axis of rotation of the circular blade can be brought. Thus, the angle at which the slice cut is made, and thus adjust the shape and size of the cut slices.

Also, in further developments, the fastening device a clamping portion for reversible and reproducible attachment, in particular via a press connection by means of a clamping screw, preferably a thumbscrew. By means of this clamping screw thus the fastening device together with the remaining Schneidguthalter on the carriage wall by pressing the clamping portion, in particular by tightening the clamping screw, can be determined easily and functionally accurate.

The installation and / or uninstalling in embodiments of the invention is particularly simple, in which the cutting material holder can be fastened to the carriage wall without tools. For this purpose, for example, the above-mentioned clamping screw having an actuating head.

In a particularly advantageous embodiment, the material to be cut, in particular the support for receiving the material to be cut, one or more means for fixing the material to be cut relative to the support of the material to be cut, for example in the form of one or more counter-holder on. Thus, the material to be cut in the Schneidguthalter be held securely.

This can be very important, especially with a diagonal cutter. An oblique cutter -compared with a vertical cutter-also cuts a disk from the inside at a right angle from the material to be cut. The axis of rotation of his circular blade and thus also his slide plate are tilted to the horizontal but in contrast to the vertical cutter. Now, if a slicer is mounted on a slant cutter - and thus potentially further increases the inclination of the material to be sliced against the horizontal - then overfilling of the sliced material can be prevented by the means for fixing. Safety at work can be further reduced Significantly improve that for a diagonal cut the material to be cut no longer needs to be held manually or a user is not "seduced" to hold the material to be cut by hand.

Often, the carriage has a plurality of carriage walls, in particular a slide front wall located in the direction of thrust forward and a slide rear wall located in the direction of pushing. Then, the fastening device for the purpose of a snug fit the Schneidguthalters be attached to a arranged in the cutting direction behind the axis of rotation slide rear wall. Thus, essentially only compressive forces are to be dissipated via the fastening device into the carriage wall during the slice cut, instead of tensile forces.

The lateral hold of a typical strand-like material to be cut can be improved by the support of the Schneidguthalters for receiving the cut material to be cut channel-shaped, in particular with a U-shaped or V-shaped cross section is formed.

The Schneidguthalter or at least its support for receiving the cutting material to be cut can be made in a particularly simple and inexpensive embodiments of the invention of molded sheet metal.

In particular, the cutting material holder or at least its support can be integrally formed in preferred developments of these embodiments.

In a particularly preferred embodiment, the fastening device is rigidly connected to the other Schneidguthalter, in particular with the support.

Alternatively or additionally, in other embodiments, the support for receiving the material to be cut can have at least one movable wall section which is adjustable, in particular tiltable and / or displaceable. Then the support can be adapted to the geometry of the material to be cut.

In particular, in preferred developments of the movable wall portion may be designed so that the geometry of the support can be adapted in each case to the cross section of the cutting material currently being cut.

A further improvement can be achieved by embodiments of the invention in which the cutting material holder has a fixing device for fixing an element of the carriage, in particular a rest holder. In fact, typically, the carriage usually has further elements, such as a food holder, which are not absolutely necessary or at least not used when the material to be cut is used. By means of the fixing device, these further elements can be fixed so that they do not hinder the operation of the disc cutting machine with the Schneidguthalter.

For this, it may be provided in further developments that the remainder holder can be fixed when he is in a certain position on a rail for shifting the food holder. This can be particularly by a corresponding embodiment of the Reach the fixing device. The fixing device may, for example, have a tensioning arm, by means of which the residue holder can be held in a desired position.

The slicing machine according to the invention can be designed as a vertical cutter or as an oblique cutter. It is conceivable, in particular, that both vertical and oblique cutters can be equipped and used with the above-described embodiments of Schneidguthaltern, even if a particular embodiment of a Schneidguthalters should be described (or useful) only in connection with a type of disc cutting machine ,

Since the cutting material holder according to the invention, as explained above, can be used in a large number of slicing machines, it is even conceivable to use the sliced product holder detached from a specific slicing machine. For example, the Schneidguthalter can be used as - in particular modular- accessory and / or as a retrofit.

In a further class of embodiments of the invention, the cutting material holder can alternatively or additionally be aligned at an angle β in a plane perpendicular to the cutting plane E, in a vertical cutter thus in an at least substantially horizontal plane. As a result, an oblique gate of the material to be cut can also be effected by tilting relative to the circular blade, for example in the at least substantially horizontal plane. For this purpose, for example, an adjustable and / or adjustable joint may be provided on the fastening device, with which the support is rotatable relative to the fastening device in the at least substantially horizontal plane.

To fulfill the hygiene requirements may further be provided that the material to be cut comes into contact only with flat or at least substantially flat surfaces, in particular the Schneidguthalters. Other surfaces and / or other elements such as screws, gaps, etc. may, preferably already structurally, be configured or positioned away from the intended location of the cutting material.

Further features and advantages of the invention will become apparent from the following detailed description of an embodiment of the invention with reference to the figures of the drawing, which show details essential to the invention, and from the claims. The individual features may be implemented individually for themselves or for a plurality of combinations in variants of the invention.

In the schematic drawing embodiments of the invention are shown, which are explained in more detail in the following description.

For easier understanding of the invention, in the following, as far as possible, corresponding reference numerals are used for corresponding elements, wherein elements of alternative embodiments are marked with an apostrophe.

The Fig. 1 shows a first embodiment of an electrically operated disc cutting machine 10 according to the invention for

Cutting off slices of, in particular, strand-like material to be cut, preferably food. The slicing machine 10 is formed in this embodiment as a vertical cutter.

It is equipped with a cutting device 12 which comprises a circular blade 16 rotating in a cutting plane E about a rotation axis X perpendicular to the cutting plane E and driven by a blade motor 14 . The slice cut and in particular the knife motor 14 are controlled and monitored by means of an input and control unit 18 .

Furthermore, the disc cutting machine 10 has a carriage 20 which carries a carriage plate 22 in a carriage plane S perpendicular to the cutting plane E and at least one carriage wall 24 , which protrudes from the carriage plane E, and a Schneidguthalter 26, a support 28 with bearing side surfaces 29 for receiving of the cutting material to be cut and which is designed to bring the material to be cut at an angle α <90 ° relative to the cutting plane E to the circular blade 16.

The item to be cut 26 has a fastening device 30 for accurately fitting the Schneidguthalters 26 on the carriage wall 24.

For slicing the carriage 20 is moved along a cutting direction R. Thus forms the carriage wall 24, at which the Schneidguthalter 26 according to the Fig. 1 is fixed, viewed in the cutting direction R, a carriage rear wall of the carriage 20th
The Figures 2 and 3 show perspective views of the carriage 20 with the arranged on the carriage wall 24th Slicer 26 of the Fig. 1 , Fig. 3 13 illustrates the carriage 20 in a perspective view from the circular blade 16 (see FIG Fig. 1 ) seen from. It shows Fig. 3 for illustrative purposes, only a portion of the carriage wall 24th

The fastening device 30 has a clamping section 32 with a clamping screw 34 configured as a knurled screw.

By means of the clamping screw 34, the item to be cut 26 can be reversibly and reproducibly attached to the carriage wall 24, in particular by means of a press connection clamped to this, are. For this purpose, a corresponding actuation or rotation of an actuating head 36 of the clamping screw 34 is sufficient. The cutting material holder 26 can thus be attached to the carriage wall 24 without tools.

The fastening device 30 can thus be reversibly released from the carriage wall 24 by means of the clamping screw 34 and fixed thereto. In particular, the fastening device 30 can be fixed at defined, reproducible positions relative to the carriage wall 24. In particular, the defined, reproducible position relative to the carriage wall 24 is a position at which the carriage wall 24 forms an engagement protection, which rises vertically from the carriage wall 24. This vertical elevation of the carriage wall also serves as a vertical stop for the fastening device 30.

As can be easily seen, the angle α, ie the inclination angle of the support 28 and thus also the cutting angle, can be separated under the discs from the material to be cut, can be adjusted by the depending on the desired inclination of the support 28 the Fixing device 30 is fixed at different positions of the carriage wall 24.

In particular, based on Figure 3 It can be seen that the cutting material holder 26 is arranged flush with the knife-side edge of the carriage 20. For this purpose, the support side surfaces 29 are bevelled in accordance with the angle α or, for these typically expected values, with respect to a support bottom 38 of the support 28.

Fig. 4 represents the Schneidguthalter 26 of Fig.1 in perspective in a view from below.

It can be seen first that its support 28 is formed as a sheet, in particular as a sheet metal. The support 28 is shaped like a channel. Their channel-shaped, in particular U-shaped, cross-section is produced by means of press-forming. The distance and the lateral inclination angle of the two side surfaces 29 of the support 28 are tuned to typically expected dimensions of the material to be cut.

The fastening device 30 is rigidly connected to the remaining Schneidguthalter 26. Overall, the Schneidguthalter 26 is thus formed in one piece.

Furthermore, the fastening device 30 has fastening recesses 40 formed as slots in the region of its clamping section 32, which provide an accurately fitting attachment of the material holder 26 to the carriage wall 24 (see FIG Fig. 1 ) enable.

Fig. 5 shows a perspective view of another embodiment of the disc cutting machine according to the invention 10 ' with a carriage 20', on whose carriage wall 24 ' a Schneidguthalter 26' is installed. Also, the carriage 20 'has a carriage plate 22' .

The slicing machine 10 'and in particular its sliced product holder 26' largely corresponds to the slicing machine 10 Fig. 1 so that only particularities and differences of this embodiment are described below.

The slicing machine 10 'is designed as an oblique cutter. Your slide 20 'has in contrast to the carriage 20 from Fig. 1 a rest holder 42 'disposed on a carriage front wall 44' of the carriage 20 '.

The Schneidguthalter 26 'has an element holder 46' on. This comprises a length-adjustable, in particular telescopic, Elementehalterarm 48 '. The element holder 46 'forms a fixing device for fixing the rest holder 42'. It fixes the remainder holder 42 'when mounted Schneidguthalter 26' in a specific, predetermined rest position, in this embodiment, in particular, substantially vertically erect. In particular, the element holder 46 'supports the residue holder 42' via its element holder arm 48 'on the carriage wall 24'.

The element holder 46 'can be adapted to different disc cutting machines by changing the length of the element holder arm 48'.

Fig. 6 shows the carriage 20 'with the Schneidguthalter 26' in a perspective side view overlooking the circular blade of the disc cutting machine 10 'from Fig. 5 ,

It can be seen that the carriage 20 'has a rail 50' , on which the rest holder 42 'is slidably disposed. Thus, the rest holder 42 'can be moved into a position suitable for fixing by the element holder 46'.

Finally, the show FIGS. 7 and 8 the slicer 26 'of the embodiment of the slicing machine 10' according to the Fig. 5 as a perspective side view (see Fig. 7 ) as well as a perspective view from above (see Fig. 8 ).

In particular, based on Fig. 7 it can be seen that the support 28 ' of Schneidguthalters 26' has two bearing side surfaces 29 ' , one of which is formed as a movable wall portion 52' . By means of a designed as a fixable hinge wall adjustment 54 ' , the movable wall portion 52' tiltable and thus formed adjustable. The geometry of the support 28 'can thus be adapted to the particular cutting material to be cut, in particular its cross-section.

By side surface passage openings 56 ' also grip counter-holder 58' through one of the support side surfaces 29 ' therethrough . Via a hinge, the counter-holders 58 'can be tilted about an axis G parallel to the support base of the support 28'. Thus, the counter-holder 58 'cutting material to be cut in the support 28' and relative to the carriage plate 22 '(see Fig. 5 ). The anvils can also be pushed up and down in the side surface passage openings. This is done by the handle on the back (in the in the embodiment of Fig. 5 the axis G 'is located) moves accordingly.
