Description

The invention relates to a device and a method of cutting a food to be cut with at least one flat surface, especially a fish or a fish fillet, with a feed device for conveying the food to be cut a cutting ramp and a cutting knife which is rotating on a support component is arranged to rotate the cutting knife while rotating carrier component around the axis of rotation repeatedly past the cutting ramp move so that when A disc moves the cutting knife past the cutting ramp with the help of the cutting knife of the food to be cut can be cut off.

An apparatus and method for cutting are, for example, from publication WO 02/064332 known. To separate a slice from the food to be cut, becomes a cutting knife, which on the one hand due to its arrangement on a rotating support component about an axis of rotation of the carrier component and on the other hand rotates about its own axis of rotation on the cutting ramp moved past so that a Cut across the length of the fish to be cut. The cut at Separation of the disc from the material to be cut starts on one of the non-flat sides of the material to be cut. With such cutting devices, for example when cutting fish fillet slices with a predetermined size and defined Weight cut off. A satisfactory one in this regard Must get cutting result the fish fillets are fed to the cutting process in a frozen state, so that Cuttings have sufficient strength. If the ones to be cut Fish / fish fillets not at a sufficiently low temperature be held, leads this to the fact that Cutting material to be cut in edge areas where the cut starts to separate the disc, compressed by the cutting knife or is squeezed. Cutting non-frozen fish / fish fillet, for what in Due to the increased consumption of fresh produce, there is an increasing need exists, is not possible using the known cutting device.

From the publication EP 1 048 417 A1 A device for cutting food is known in which a cutting knife performs a repetitive, linear forward and backward movement in a direction parallel to the feed direction, in which the food to be cut is conveyed into the area of the cutting ramp with the aid of the feed device. As a result of the repetitive linear movement, the cutting knife is repeatedly guided past the cutting ramp in order to separate slices from the food. With the aid of the provided linear movement of the cutting knife parallel to the feed direction of the food to the cutting ramp realized with the feed device, it is possible to carry out a cut in a longitudinal direction of the food when cutting off a slice of the food to be cut. However, the provision of the repetitive linear movement of the cutting knife has disadvantageous consequences for the design of the cutting device. Compared to cutting knives on rotating carrier components, the design effort is considerably higher, since the acceleration forces occurring during the repetitive linear movement of the cutting knife have to be absorbed by the device construction. Overall, the number of cutting operations per unit of time is limited due to these design restrictions.

The object of the invention is a Device and a method for cutting a to be cut Food with at least one flat surface, in particular a fish or a fish fillet of the type mentioned at the beginning specify where the disadvantages of the prior art are overcome are, in particular the possibility to Slicing food that is not frozen have a low cut resistance with a high cutting sequence be made possible.

In the case of the essentially flat foodstuff to be cut, this prevents the foodstuff to be cut from being squeezed in the outer regions when the cutting knife is attacked and slices with an uneven thickness being produced. With the help of the new device and the new method, slices of any thickness can be cut with the same quality. The use of the cutting knife on the rotating support member enables a high cutting sequence without the increased design effort that must be used, as is necessary to compensate for acceleration forces in the cutting device known from the prior art, which a repe ting, linear forward and backward movement of the cutting knife uses.

An expedient embodiment of the invention can provide that on the rotating support component at least one further cutting knife is arranged around the at least one another cutting knife to cut another slice of the food to be cut while rotating the rotating one carrier component to repeatedly move past the cutting ramp, at least that another cutting knife on the rotating carrier component is arranged so that at Moving the at least one further cutting knife past the Cutting ramp for cutting the further disk from the to cutting food a cut is feasible in the area of at least one flat surface of the food to be cut.

The discharge device can consist of several conveyor elements put together. For example, the cut disk can first be opened a conveyor roller fall to a conveyor belt promoted to become.

The most exact transfer possible the force of the cutting knife / the at least one further cutting knife for hurling the cut disc onto the discharge device is at an appropriate training the invention achieved in that the rotating support member with the cutting knife / the at least one further cutting knife and the cutting ramp are arranged so that the cutting knife / at least one other cutting knife on the cut disc / die another cut disc transferred Force essentially along a direction of movement of the material to be cut Food when moving the food to be cut over the Cutting ramp works.

A space-saving design of the Device for cutting is in an advantageous embodiment the invention achieved in that a conveying direction of the feed device at Promote of the food to be cut and a conveying direction of the discharge device to promote the cut disk substantially parallel to each other run.

The cutting ramp and are useful the cutting knife / the at least one additional cutting knife on the rotating support member relocatable relative to each other to set a cutting angle to be able to. This way it is possible dependent on from the specific training of the flat food to be cut a desired one Choose the shape of the cut disc.

A flexible use for different foods Device is thereby in a preferred embodiment of the invention created that Cutting knife and / or the at least one other cutting knife solvable on the rotating support member are attached. This also enables replace the cutting blades for replacement or maintenance.

An optimized cutting result can can be achieved in that the rotating support member with the cutting knife and / or the at least one further cutting knife and the cutting ramp are formed to move the cutting knife past and / or the at least one further cutting knife on the cutting ramp for Cut the slice off the food to be cut Make cut, which is essentially in a longitudinal direction of the food becomes.

To prevent the cutting knife from entering To facilitate the food to be cut, an expedient embodiment of the invention can provide that a cutting plane in which the cutting knife and / or the at least one further cutting knife move as it moves past the cutting ramp, and a movement plane in which the food to be cut moves moved over the cutting ramp, are formed at a small angle to each other. The small angle is preferably in a range from a few degrees to about 45 degrees.
