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 which comprises a mounted in a machine housing, rotating in a cutting plane circular blade with an enclosed by a tower-shaped portion of the machine housing electric motor for driving the Cutting device, wherein the tower-shaped portion is arranged on the side facing away from the cutting edge with respect to the cutting edge facing away from the cutting edge, and with a storage area which remains free for cut slices of the cutting material.

Such disk cutting machines are known, for example from the DE 10 2009 060 465 A1 ,

The cut material, in particular in automatically operated slicing machines for rope-shaped foods, such as sausages, ham, salmon, cheese, etc., is moved by means of a feed device on a feed surface against the cutting device, usually in the direction perpendicular to the cutting plane, in which usually one or more rotating blades rotate 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.

The DE 10 2009 060 465 A1 describes a generic electrically powered disc cutting machine with the features defined above, comprising a drive tower and a base plate on which the drive housing is mounted freely supporting at least one in the vertical direction extended support column. Compared to other known from the prior art disc cutting machines, such as those in the DE 103 17 319 A1 or the AT 385939 B are described, the slicing machine according to the DE 10 2009 060 465 A1 characterized by an embodiment of the support column such that below the cutting device between the drive housing and the base plate, a gap remaining in the horizontal direction remains free, in which at least one accessory device for the further processing of cut off Scheidegut is arranged, wherein a connection of the accessory device is received in the drive housing , As a result, the machine has a particularly compact design and enables easy conversion to different operating modes, with accessories needed for this purpose being able to be accommodated in the same housing as the drive.

The in the DE 10 2009 060 465 A1 described slicing machine has a plurality of openings in order to support additional units for the storage area - for example, a conveyor belt. However, these additional units can be subjected in the known arrangement, however, due to the limited and sometimes difficult accessibility of the components on and around the drive tower only with relatively high effort thorough cleaning, which, however, just in the processing of food such as sausage, meat, fish or cheese quite is often required.

Object of the present invention is in contrast, in a generic professional slicing machine of the type described above cost and with simple technical means to improve the ability to clean the components noticeable while providing a universally usable storage area.

According to the invention, this object is achieved in an equally simple and effective manner in that the machine housing has an opening in the region of the tower-shaped section through which a central storage system carrier suspended in the machine housing engages in the storage area, which opening is designed to be different mechanical storage components for receiving cut slices of Schneideguts, such as a storage table, a receiving plate, a turntable, a transport table or a conveyor belt in the storage area can wear.

According to the invention, therefore, the use of a system carrier is proposed, which receives different - especially electrically driven - components for further transport or processing of the cut slices of Schneideguts and is attached hanging on the drive tower or in the drive tower.

Very particularly preferred embodiments of the disc cutting machine according to the invention are characterized in that the central storage system carrier suspended in the machine housing is arranged to float freely via a holding arm. In particular, only a single support arm is provided, so that only a single opening for attachment of the central storage system support is needed. Hanging system support means in particular that the system carrier is suspended freely suspended and refers to the Storage area. A suspended suspension may also include embodiments of a support arm over which the central storage system support is freely suspended in the storage area, wherein the support arm is folded one or more times and supported in the machine housing above or laterally or below the storage area.

In further particularly advantageous embodiments of the storage system carrier is adjustable via a lifting drive in its vertical height position. This allows constant drop heights of the slices of the cut material to be cut, which in turn improves the quality of the achieved cutting result.

In order to reliably prevent the ingress of dirt or spray into the motor tower, particularly preferred developments are characterized in that the storage system carrier extends vertically downwardly through an opening of the machine housing, and that a sealing device is provided, which in the vertically lowest Position of the linear actuator, so in the preferred cleaning position, the opening of the machine housing seals to the outside.

Also advantageous are embodiments of the disc cutting machine according to the invention, in which the central storage system carrier - for example for cleaning or maintenance purposes - is detachably suspended in the machine housing. In particular, it is provided that the storage system carrier in a simple manner, preferably without tools by hand, is removable.

Particularly preferred embodiments of the disc cutting machine according to the invention are characterized in that at least one of the storage components designed to be movable and directly or indirectly driven electrically.

In advantageous developments of these embodiments, an electric drive for horizontal adjustment of a load plate is provided, which in particular allows the generation of 2-dimensional figures of the stored on the load plate Schneidegut discs. The electrical supply of the drive of the load plate is in variants of these developments quite simply via a suspension - in particular on a weighing - out.

The drive device for driving the storage components is arranged in a particularly preferred compact developments of these embodiments in a cavity of the central storage system carrier.

Preferably, a plurality of mutually exchangeable storage system support for different mechanical storage components or different groups of mechanical storage components are provided, whereby the variable usability of the disc cutting machine according to the invention is further increased.

In this case, a first class of developments of these embodiments is particularly advantageous in which the central storage system carrier is designed so that it can accommodate either a turntable or a transport table.

These developments can be further improved by the fact that a drive device is provided, which comprises a pivot pin for rotating the turntable and a transport rod for moving the transport table.

The turntable and / or the transport table and / or the conveyor belt may be designed to be removable for assembly, maintenance or cleaning purposes.

Another class of advantageous developments of these embodiments of the disc cutting machine according to the invention is characterized in that the design of the central storage system carrier allows the inclusion of a conveyor belt.

In particularly preferred variants, a drive device is provided, which comprises a PTO shaft for moving the conveyor belt.

Also advantageous are developments in which the drive device is arranged to drive the storage components in the tower-shaped portion of the machine housing and drives a gear via a pivot and / or a transport rod and / or a PTO.

In order to determine the weight of the cut material to be cut - if possible "online" while the cutting process is running - known food slicing machines already have integrated weighing devices. So are so-called "Slicer" with built-in scales in DE 10 2008 038 063 A1 or in DE 21 49 209 A described. However, such simple slicers are designed only for "smaller" applications and in particular not for professional use, such as in a sausage factory, and therefore have neither a "motor tower" nor a movable slide on. In contrast, in a class of preferred embodiments of the invention, a weighing cell with weighing sensor is within the tower-shaped portion of the electric motor enclosing the Machine housing arranged at a vertical height of the cutting device.

This geometry according to the invention significantly saves height of the engine tower and the entire device can be made significantly more compact. In addition - without additional measures - solely by the proposed arrangement of the weighing device at the same level with the cutting device - ie above the storage area for cutting material - the hygiene conditions significantly improved because no cutting material particles pollute the weighing more. Of course, this also automatically improves the operational safety and the ease of maintenance of the device.

Particularly user-friendly developments of these embodiments, in which the weighing sensor is adjustable via a lifting drive in its vertical height position to compensate for the stack height of Schneidausut. The lifting drive can be moved here, for example via a worm drive with a lifting spindle from the electric motor.

Particularly preferred due to their simple structure are variants of these embodiments, in which the central storage system carrier is suspended via a holding arm on a load cell in the machine housing.

Alternatively, other practical and very compact variants of the central storage system carrier having a support arm, on which a load cell is arranged.

In an advantageous embodiment it can be provided that the weight of the empty storage system carrier is detected via the weighing cell. About the empty weight of the storage system carrier arranged on the system tray components can be detected automatically. For this purpose, an evaluation device may be provided which has different tare weight classes, each tare weight class being assigned a corresponding component, in particular a turntable or conveyor belt or delivery table. The evaluation device selects the corresponding component via the tare weight class and can automatically activate or activate a drive device necessary for the respective component.

For operation of the disc cutting machine without scale, the weighing transducer can be replaced with a solid rod. In this way, the slicing machine according to the invention can be easily and easily converted to such a simple embodiment without effort.

In a class of further developments, the weighing transducer comprises an exchangeable bending rod. This can be easily replaced for service purposes, for the realization of different sensitivity levels of the weighing device and for operation in different accuracy classes.

An inexpensive alternative to this class of developments provide further developments in which the load cell is designed as a strain gauge cell with strain gauges.

Another class of further training is characterized by the fact that the load cell is designed as a string vibration measuring cell, whereby a particularly high accuracy of the weighing results can be achieved.

In order to increase the reliability and reduce the susceptibility to interference, in preferred variants, an electronic filter device is provided for eliminating any mechanical or electrical interfering signals acting on the measuring signal of the weighing device.

Finally, particularly advantageous developments of the above embodiments are characterized in that the electronic filter device is electrically connected to a control device for a stripper and / or a chain frame and / or to a carriage travel sensor and / or to a rotational speed control for the electric motor. The interaction of the electronic filter device with potential mechanical or electrical interference sources within the disc cutting machine according to the invention results in a harmonious and uniform overall electronics in terms of increased reliability.
