Description

Slicing machine with external

Sled guide and knife lock

The invention relates to an electrically operated disc cutting machine for cutting slices of, in particular, stranded cutting material, preferably food, with a

Cutting device, which comprises a mounted in a machine housing, rotating in a cutting plane circular blade, and with a substantially flat support plate bearing surface for laying the cutting load carrying carriage, which guided parallel to the cutting plane via a slide foot along a rigidly connected to the machine housing slide rail parallel to the plane of the support plate, as well as with a device for cutting thickness adjustment of Schneideguts comprising a stop plate, wherein the Schlittenfuß via a first push rod, which cooperates with a control disc which is adapted to adjust the stop plate, for a tilting movement of the

Schlittenfußes can be locked or released. Such disk cutting machines are known, for example, from EP 0 823 314 A1 or WO 96/05952 A1.

The Schneideg ut, especially in automatically operated disc cutting machines for rope-shaped foods, such as sausages, ham, salmon, cheese, etc., is moved by means of a Zuseteileinrichtung against the cutting device, usually in the direction perpendicular to the cutting plane, in which usually one or more rotate rotating circular knives to cut off slices from the conveyed material. The drive of the cutting device is carried out by an electric motor, the protection against splashing water and Schmutzutzg and mechanical protection against external interference from

Machine housing is completely enclosed. In order to be able to separate the desired disc by the rotating blade cut material, the cutting material lying on the support surface of the platen is moved by means of a carriage parallel to the cutting plane and moved towards the rotating knife blade until the rotating knife Sch enidegut completely cut through and the disc cut off from the material to be cut. Usually, the support plate is rigidly connected to a carriage foot which leads from the support plate to nten and movably supported on a slide rail, which in turn is rigidly connected to the machine housing,

Such a construc tion is described for example in DE 200 20 065 U l. The carriage base is supported here with an outside slide guide from above on the slide, wherein the Aufna hme occurring torques also sliding surfaces on the Machine housing are provided, on which the slide foot is slidably mounted from above.

A two-point storage is in DE 201 18 836 Ul

described slicer with internal

Carriage guide provided, wherein the slide foot in turn supported on a slide and in addition via a roller - again from above - on a rigidly connected to the machine housing running rail.

A three-point bearing of the carriage foot via a slide rail and two roller-shaped support elements is shown in the cited EP 0 823 314 AI. However, the carriage guide is located here outside the machine housing freely lying and thus extremely susceptible to dirt and not really suitable for a hygienic as delicate use as in the food industry.

In contrast, the WO mentioned in the einga ngs cited offers

96/05952 AI described slicing machine improved cleaning options and simplified maintenance.

In such professionally used disc cutting machines, it is also necessary to dump the carriage for cleaning purposes. For safety reasons, this must only be done with the stop plate provided if the cutting force is set to Nu ll. In WO 96/05952 AI a knife protection lock is shown, which in fact only allows unfolding of the carriage when the set cutting thickness is less than zero. However, this construction does not allow absolute splash protection. Object of the present invention is in contrast, a generic disc cutting machine of the beginning

described type cost and with simple technical means to improve that the machine if possible

Compact design and optimum work safety thanks to a secure blade protection lock also enables a high splash water protection of the housing, increases hygiene in the operation of the machine and further improves the handling during cleaning and especially the protection to the cutting area.

According to the invention, this object is achieved in an equally surprisingly simple and effective manner in that the first

Push rod acts on a locking disc, which rotates on the

Sliding rail is mounted and has a control contour, which cooperates via a second push rod with the control disk for releasing or blocking a rotational movement of the locking disc and thus a tilting movement of the carriage foot that the

Machine housing has an at least partially extending between the support plate and carriage foot partition, which on their the

Platen facing away from a guide space partially encloses, in which the slide rail is arranged, and that the second push rod engages through the partition wall.

In this way, a cost S pritzwassersch utz of the housing is possible with cost-effective means and a spatial

Separation of the guide elements of the carriage from the drip area of the cutting material to be processed - such as from dripping meat juice - and on the other hand, a separation of the food area of

Components with bearing grease or increased residues of abrasion alone ensured by the geometry of the arrangement. Furthermore Simplified maintenance and cleaning of this particularly dirt-prone area below the platen is possible. The outside slide guide is easily accessible and therefore easy to keep clean so that contamination influences on the quality of the cutting material to be processed can be minimized or - with careful operation - even eliminated.

The slicing machine according to the invention can be designed both as a vertical cutter and in the form of a slanted cutter.

Particularly preferred is an embodiment of the disc cutting machine according to the invention, in which the second push rod is designed as a spring-loaded bolt, which, preferably

splash-proof, is guided by the partition and transmits the movement of the locking disc on the control disc, whereby an automatic tracking is enabled.

movable and it is a barrier rib on the machine housing

provided, which cooperates in a certain angular position of the locking disc to the slide with a profile of the machine housing such that a pivoting of the carriage only in a certain axial position of the carriage relative to the slide rail, in particular in an end position, is possible. A particularly smooth storage results when the

Locking disc via a slide bush is rotatably mounted and axially displaceable on the slide rail. Tilting the locking disc can be effectively prevented. The profile can - depending on the specific purpose of the machine - integrally formed, cast, glued or screwed in further developments of this class of embodiments on the machine housing. In particular, a screw allows easy replacement of the profile. In practice, a third class of embodiments of the disc cutting machine according to the invention, in which a pivotally mounted locking strip is provided, which is arranged such that it transmits the movement of the locking disc on the second push rod. In particular, it is provided that the locking strip extends parallel to the slide over a distance corresponding to the travel of the carriage, which allows a swinging the whole line, In a further advantageous embodiment of the disc cutting machine according to the invention, the slide rail at its two opposite end faces respectively stored or attached in an end wall of the machine housing, and the two end walls of the partition cover the enclosed guide space on both sides of the front side. On the one hand, this combination of measures ensures optimum absorption of the torques acting on the two partition wall sections and, on the other hand, further enhances hygiene by minimizing the effects of contamination. A particularly preferred class of embodiments of the invention is characterized in that the carriage base is movably supported by at least two support members against the machine housing, and that the at least two support elements are slidably received within the guide space and supported against the partition, wherein the first support member in an operating state of the disc cutting machine on the side facing away from the carriage of a first partition wall portion of the partition, which extends below the platen parallel to the plane of the support plate, a bottom supports, and that the partition wall has a second partition wall portion, the angled relative to the first partition wall portion extends straight or obliquely downwards, wherein the second support element is laterally supported against the second partition wall portion. A particularly compact construction of the slidable foot allows, in particular, the two-part construction and the geometrical arrangement of the partition wall.
