Description

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 comprising a mounted in a machine housing, rotating in a cutting plane circular blade, and with a substantially flat support plate with support surface for laying the Schneideguts carrying carriage, which is guided parallel to the cutting plane along a slide foot along a rigidly connected to the machine housing slide rail and parallel to the plane of the platen, and with a device for cutting thickness adjustment of Schneideguts comprising a stop plate, the Schlittenfuß via a first push rod , which cooperates with a control disk, which is designed for adjusting the stop plate, can be locked or released for a tilting movement of the carriage foot.

Such disk cutting machines are known, for example from the EP 0 823 314 A1 or the WO 96/05952 A1 or the DE 4429628 A1 ,

The material to be cut, in particular in automatically operated slicing machines for rope-shaped foods, such as sausages, ham, salmon, cheese, etc., is moved by means of a delivery device against the cutting device, usually in the direction perpendicular to the cutting plane, in which usually rotate one or more rotating circular blade to cut off slices of conveyed material. The drive of the cutting device is carried out by an electric motor, which is completely enclosed to protect against splashing water and pollution and for mechanical protection against external interference from the machine housing.

In order to be able to separate the desired disc from the material to be cut by the rotating blade, the material to be cut on the support surface of the support plate is moved by means of a carriage parallel to the cutting plane and moved towards the rotating knife blade until the rotating blade completely cut through the cutting material and the disc from Cutting material has cut off. 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 for example in the DE 200 20 065 U1 described. 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.

A two-point storage is at the in DE 201 18 836 U1 described slicing machine provided with internal slide guide, wherein the slide foot in turn on a slide rail and additionally via a roller - again from above - supported 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 in the cited above EP 0 823 314 A1 shown. 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, offers in the also cited above WO 96/05952 A1 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 closed when the cutting thickness is set below zero. In the WO 96/05952 A1 a knife guard lock is shown, which in fact only allows the carriage to fold out 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 to improve a generic disc cutting machine of the type described above cost and with simple technical means to the extent that the machine with the most compact design and optimal safety through a safe blade protection lock and a high splash protection of the housing allows hygiene increases in the operation of the machine and the handling during cleaning and in particular the protection of the cutting area is further improved.

According to the invention this object is achieved in a surprisingly simple as well as effective manner in that the first push rod acts on a locking disc which is rotatably mounted on the slide and has a control contour, which via a second push rod with the control disc for releasing or blocking a Rotary movement of the locking disc and thus a tilting movement of the carriage foot cooperates, that the machine housing has an at least partially extending between the support plate and Schlittenfuß partition that partially surrounds a guide space on its side facing away from the support plate, in which the slide is arranged, and that the second push rod through the partition engages through.

In this way, with cost-effective means extensive splash protection of the housing allows 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 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 formed as a spring-loaded bolt, which is preferably splash-proof, passed through the partition and transmits the movement of the locking disc on the control disc, whereby an automatic tracking is possible.

A particularly smooth bearing results when the locking disc is rotatably mounted on a sliding bush 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 bar extends parallel to the slide rail 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 is mounted or fixed at its two opposite end faces in each case 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 elements 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 element 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 support plate parallel to the plane of the support plate, supported from below, and that the partition wall has a second partition wall section, 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 design of the carriage foot allow in particular the two-part construction and the geometric arrangement of the partition. The geometry of the support by up against the first partition wall portion and to the side against the second partition wall section provides in conjunction with the third Abstütztort on the slide a stable three-point mounting with optimum balance of forces and torques especially in relation to the operating condition tilted maintenance position of the support plate safely.
