Description :

The invention relates to an electrically operated

Slicing machine for cutting slices

in particular strandformigem cutting material, preferably food, with a cutting device comprising a stored in a machine housing, rotating in a generally vertical cutting plane circular blade, and with a substantially planar

Platen with support surface for laying the cutting material carrying carriage, which along a slide foot along a rigid with the

Machine housing connected slide parallel to the cutting plane and parallel to the plane of the support plate is linearly movable, wherein the support plate of the carriage for cleaning purposes

at least 90 ° away from its working position away from the circular knife

is pivotally mounted. Such a slicing machine is known, for example, from DE-A 1 782 009.

The cutting material, especially in automatically operated

Sliced food slicing machines, such as sausages, ham, salmon, cheese, etc., are moved by means of an adjusting device against the cutting device, usually in the direction perpendicular to the cutting plane, in which usually one or more rotating circular knives circulate to cut off slices of conveyed sliced material , The drive of the cutting device is made by an electric motor, which protects against splashing water and pollution and for mechanical protection against external interference from

Machine housing is completely enclosed.

Now to the desired disc by the rotating blade from

Cutting material to be cut off, the material to be cut on the

Placed surface of the support plate lying by means of a carriage parallel to the cutting plane and moved toward the rotating knife blade until the rotating knife has cut through the cutting material completely and cut off the disc from the material to be cut. Usually, the support plate is rigidly connected to a carriage foot, which leads from the support plate down and is movably supported on a slide rail, which in turn is rigidly connected to the machine housing.

Such a construction is described for example in DE 200 20 065 Ul. The slide foot is supported here with an outer slide guide from above on the slide, wherein for receiving the torques occurring also sliding surfaces on the

Machine housing are provided, on which the slide foot is slidably mounted from above. For the purpose of cleaning the platen - which is especially useful for slicing machines in food use

hygienic reasons is essential and therefore must be done frequently in regular, relatively short intervals - a mechanism is required by means of which the support plate can be moved out of the cutting area of the circular blade and placed as possible in a tilted cleaning position.

DE 103 07 084 AI describes a disc cutting machine, in which the support plate is guided parallel to the cutting plane and parallel to the plane of the support plate linearly movable, wherein the support plate of the

Slides can be tilted to obtain a stable support for smaller diameters of the slices to be cut. However, for geometric reasons, a tilting of the support plate is only possible here at most by an acute angle relative to the plane of the plate in its working position in the cutting operation. Therefore, handling is cumbersome and a thorough cleaning of the support plate in this pivoted position very difficult, if not impossible, at least not provided.

In contrast, the above-cited DE-A 1 782 009 shows a

generic disc cutting machine with a

Movement mechanism that allows the platen in one

Cleaning position by more than 90 ° from its working position of

Circle knife away to pivot about an axis parallel to the direction of travel of the carriage axis, so that the plate can be cleaned easier and more thorough. However, the pivoting of the support plate takes place in a room area next to the

Slicer in which the load with

Cutting material takes place. There then inevitably constantly free space be held, what the total effective footprint of the

Machine at the site increased significantly.

Object of the present invention is in contrast, a

generic disc cutting machine with the above

described features cost and with little technical effort to improve that the machine needs no additional space on their load side with the most compact design and optimal safety, which must be kept permanently for the required cleaning work, with the handling further improved and safety additionally increased.

According to the invention, this object is achieved in a surprisingly simple and effective manner in that the support plate of the carriage in a driven out of the working position along the slide out end position or cleaning position of the carriage about a pivot axis, the pivot angle φ between 60 ° and 90 ° hits the cutting plane, is pivotally mounted, wherein the support plate is mechanically locked in all other positions, including the working position against pivoting.

The geometric choice of the final position or cleaning position of the carriage at the end of the linear path allows easy access from virtually all sides to the platen, due to the inventively provided locking in all other

Operating positions the necessary safeguard against unintentional pivoting is achieved. In this way, with cost-effective means of design effort in the production of

Slicing machine significantly reduced due to the It can no longer be kept permanently free in the area of the loading side of the machine, so that the machine can be used very space-saving even in confined spaces.

Advantageous in handling and operation are embodiments of the slicing machine according to the invention, which

characterized in that the pivot axis angle φ between 70 ° and 85 °, preferably between 72 ° and 82 °. The slide can be at forward tilted pivot axis of the usual

Swiveled away the stop plate for cutting thickness adjustment and tilted around the horizontal in order to gain even more space for cleaning the carriage.

A class of advantageous embodiments of the disc cutting machine according to the invention is characterized in that the

Support plate of the carriage is mounted on a pivot shaft through which the pivoting about the pivot axis. In particular, it can be provided that the pivot shaft a

Locking device having the pivot shaft in

Dependence on the linearly moved position of the carriage

Pivoting releases or locks.

An alternative or additional safeguard against unwanted

Pivoting the platen provide embodiments in which the backup is done twice. The locking device comprises as the first securing device a locking of the pivot axis by being mechanically locked against rotation. As a result, an effective barrier of the carriage is achieved against pivoting. Especially can be provided that with the first fuse an improved accident protection is achieved by the pivot axis is only released when the circular blade is safely covered or in a cleaning position. The locking device comprises as a second

Securing device a support pin, with which the

pivotable part of the carriage during a linear

Traversing movement of the carriage along the slide rail or sliding axis against a surface of the machine housing slidably supported, said surface is geometrically designed so that the support pin gets out of contact with the surface only in the end position of the carriage. This ensures that the platen can only be pivoted at an end position.

Particularly preferred embodiments of the invention, in which Schlittenfuß is constructed in two parts, which enormously increases the number of design options for the design of the carriage.

In particular, it can be provided that the two parts of

Carriage foot are rotatably mounted to each other. In this case, an inner part of the carriage foot which is arranged towards the machine housing is firmly connected to the machine housing and the second part of the carriage foot, which is remote from the machine housing, is firmly connected to the carriage or the support surface. The second or outer part of the carriage foot is rotatably connected to the pivot axis. By blocking the pivot axis is achieved so that pivoting of the carriage or the support plate is effectively prevented.

Very particularly advantageous developments of these embodiments are characterized in that the two parts of the slide foot adjoin one another via an obliquely at an angle α = 90 ° - φ to the cutting plane extending surface and relative to each other around a Axis perpendicular to this surface, namely the pivot axis

are pivotable. This inclined surface acts during the entire pivoting movement as a guide surface for the parts of the carriage foot to be pivoted.

In further particularly preferred embodiments of the

Slicer according to the invention is a

Provided locking bolt with which the pivotable part of the carriage is additionally locked against pivoting. In the normal load case, this additional locking bolt absorbs a large part of the torque which is produced during an attempt to pivot the blocked carriage. Even with this simple measure, a considerable increase in reliability is achieved.

Advantageous developments of these embodiments are characterized in that the locking bolt is loaded with a compression spring or lockable by a thread, which causes a further increase in safety during operation and in particular the handling.

In an alternative class of embodiments of the invention, the support plate of the carriage is also mounted on a pivot shaft through which the pivoting about the pivot axis, but the pivot shaft is constructed in two or more parts, so that the pivot shaft is not the entire linear travel of the carriage must join on the slide. Rather, only the short front part of the carriage is moved, whereby a larger construction space is released below the platen, where else the relatively bulky pivot shaft would have to be moved. This liberated space can be used, for example, for the accommodation of elements of the drive electronics, which is an overall considerable more compact construction of the invention

Slicing machine allows.

In a preferred and easily produced development of this class of embodiments, the split pivot shaft on a coupling portion which engages with a pin or a spring in the end position of the carriage in a recess or groove and thus an otherwise rotationally fixed connection for rotating the pivot shaft and thus for pivoting the support plate releases.

In practice, also proves a further development, which can be realized in both classes of the embodiments described above and which is characterized in that a stop plate is provided for cutting thickness adjustment, which is linearly displaceable perpendicular to the cutting plane, and that the stop plate, the pivot shaft only in a linearly moved position of the carriage for pivoting releases, in which the disc cutting machine a

Schnittstärkeneinsteilung has less than zero. In this position, the stop plate hides the circular blade in the cutting plane on the front side towards the operator geometrically, which contributes significantly to passive accident protection.

Preferably, the support plate in the support surface for the

Cut a juice groove to drain liquid. This juice groove prevents the uncontrolled leakage of meat juice from the support surface while cutting sausage or meat products by catching the juice and drains defined and thus increases the hygiene when using the slicer in the food sector. A further advantageous embodiment of the invention

Slicing machine is characterized by having a

Compression spring is provided, and that the carriage only after overpressure of the compression spring on the sliding axis or slide linearly in the

End position can be moved, in which then a pivoting of the pivotable part of the carriage about the pivot axis is possible. Due to the counterpressure of the compression spring to be overcome only reaching the end position, in which a tilting of the support plate is possible at all, mechanically difficult, creating a

additional security against unintentional pivoting of the support plate is achieved.

The slicing machine according to the invention can be used both as

Vertical cutter as well as in the form of an inclined cutter to be executed.

Further features and advantages of the invention will become apparent from the following detailed description of exemplary embodiments of the invention with reference to the figures of the drawing, which shows erfindungswesentiiche details, 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. a schematic, partially transparent plan view of an embodiment of the invention

In the figures of the drawing are details of two embodiments (with one-piece pivot shaft in Figs. 1 and 2a to 2d or with two-part pivot shaft in Figs. 3a to 3d of the invention, electrically operated, usually automatic

Slicing machine 10; 30 for cutting slices of particular stranded cutting material, preferably food, represented.

The slicing machine 10; 30 has one each

Cutting device, which in a machine housing 11

rotatably mounted, rotating in a cutting plane E

Circular knife 12 includes. Next belongs to

Slicing machine 10; 30 a substantially flat

Platen 13 with support surface for laying the Schneideguts, which is supported by a carriage 14, softer on a

Carriage foot 14a along a rigidly connected to the machine housing 11 slide rail or sliding axis 15 parallel to

Cutting plane E out and parallel to the plane A of the support plate 13 is linearly movable, wherein the support plate 13 of the carriage 14 by at least 90 ° from its working position of the circular blade 12 away is pivotally mounted.

As can be seen in the upper part of Fig. 1, the support plate 13 is in the illustrated vertical cutting machine 10 in the working position of a horizontal position in which they, for example via a

Screw, rigidly attached to the carriage 14. In the lower part of Fig. 1 and in Figs. 2a and 3a, this attachment is in each case solved and the support plate 13 - usually to cleaning or

Maintenance purposes - tilted about a horizontal pivot axis s relative to the carriage 14.

Alternatively, however, the slicing machine according to the invention can also - not shown in the drawing

Embodiments - be designed as a slanted cutting machine with a different Verkippwinkel, where there is also the possibility of pivoting the support plate.

According to the invention, the support plate 13 of the carriage 14 in an out of the working position along the slide rail 15 linearly driven out end position of the carriage 14 about the pivot axis s, which at a Verschwenkachsenwinkel φ between 60 ° and 90 ° to the

Cutting plane E applies, pivotally mounted, wherein the support plate 13 is locked in all other positions, including the working position against pivoting. The Verschwenkachsenwinkel φ may in particular be between 70 ° and 85 °, preferably between 72 ° and 82 °.

As a rule, slide foot 14a will be constructed in two parts. Of the

Carriage foot has an inner part 14b facing the machine housing and an outer part 14c facing away from the machine housing on. The two parts 14b and 14c of the slide foot 14a adjoin one another via an obliquely at an angle α = 90 ° - φ to the cutting plane E extending surface F and are relative to each other about the pivot axis s perpendicular to the surface F pivoted. Besides, usually one will - not in the drawing itself

shown - compression spring be arranged so that the carriage 14 can be moved linearly in the end position only after overpressure of this compression spring on the slide rail 15, in which then a pivoting of the pivotable part of the carriage 14 about the pivot axis s is possible.

By means of a support pin 16, the pivotable part of the carriage 14 is supported during the entire linear movement of the

Carriage 14 on the slide rail 15 against a surface B of the

Machine housing 11 slidably, said surface B is geometrically designed so that the support pin 16 only in the final position of the

Schlitten 14 out of contact with the surface B device to a

To release pivoting of the support plate 13. This can be seen particularly well in FIGS. 2a to 2c and 3a to 3c.

Furthermore, a locking bolt 17 is provided, with which the pivotable part of the carriage 14 can be locked against pivoting. Not shown in the drawing

Embodiments in which the locking bolt 17 is loaded with a compression spring or can be fixed by a thread.

The embodiment shown in Figs. 1 and 2a to 2d is characterized in that the support plate 13 of the carriage 14 on a

one-piece pivot shaft 18 is supported, through which the

Pivoting about the pivot axis s occurs, and that the Pivoting shaft 18 has a locking device which releases the pivot shaft 18 in response to the position of a stop plate 19 for pivoting or locked.

In contrast, an embodiment of the invention is shown in Figs. 3a to 3d, in which the support plate 13 of the carriage 14 is mounted on a two-part pivot shaft 38, through which the pivoting about the pivot axis s. Not specifically shown are possible embodiments in which the pivot shaft comprises more than two parts. The two-part pivot shaft 38 has a coupling portion 38 a, which engages with a pin or a spring in the end position of the carriage 14 in a recess or groove and thus an otherwise rotationally fixed connection for rotating the

Pivot shaft 38 releases.

Next is a stop plate 19 for cutting thickness adjustment

provided, which is linearly displaceable perpendicular to the cutting plane E, wherein the stop plate 19, the pivot shaft 18; 38 only in a linearly moved position of the carriage 14 geometrically releases for pivoting, in which the disc cutting machine 10; 30 one

Cutting thickness setting is less than zero, so that the

Stop plate 19, the circular blade 12 in the cutting plane E front side to the operator out geometrically.

For this purpose, the pivot shaft 18 has a cam 181 which cooperates directly with the stop plate 19. The stop plate 19 is supported in the interior of the machine housing on a guide. About one

Knob 191, the stop plate 19 can be moved linearly perpendicular to the cutting plane to a cutting gap between the

Adjust cutting blade 12 and the stop plate 19, whose width corresponds to a desired slice thickness. The cam 181 is fixedly connected to the pivot shaft 18 and protrudes at the end thereof at a right angle from the longitudinal axis of the pivot shaft 18 from the side. In the position of the stop plate 19 shown in FIGS. 3a and 3b, which corresponds to a cutting thickness setting greater than zero, ie at which the cutting edge of the circular blade 12 is exposed, the cam 181 comes into direct contact with the stop plate 19 or a holder of the stop plate 19th and thereby blocks a pivoting of the pivot shaft 18. Only when the stop plate 19 is moved in front of the cutting edge of the circular blade 12, ie at a slice thickness setting less than or equal to zero, as shown in FIGS. 2c and 2d, the stop plate 19 releases the cam 181 and the pivot shaft 18 can be rotated.

The stop plate 19 is actuable bar via an adjusting device by means of a knob 191, wherein the passage area of this

Device 18 through the machine housing 11 at least

is sealed splash-tight. For this purpose - in the drawing only schematically illustrated - sealing elements D may be provided.

Not specifically shown in the drawing are embodiments in which the support plate 13 has a juice groove for draining liquid in the support surface for the cutting material.
