DESCRIPTION:
BRIEF SUMMARY
The invention concerns a cutting device.
Unlike the cut product that in the conventional cutting machines is obtained in the shape of discs, there is obtained, when using a cutting device of this kind, a cohesive end product coiled to form a helical surface.
In order to be able to offer in a manner suitable for eating, for example radishes such as are sold in beer gardens and guest houses, it is necessary even today to use a radish cutter with a crank handle. There are also known radish cutters driven by a motor. In such a cutter the rotation of the radish by means of the crank handle is eliminated. The axis of rotation in this radish cutter is horizontal the same as in the radish cutter with a crank handle. To be able correctly to use the already known radish cutter, both hands are required during the cutting operation. With one hand the motor and the cam are pushed along a guide horizontally in a direction toward a threaded spindle and a blade. With the same hand the starting push-button is pressed as long as the motor has to run. With the other hand the curled radish coils that move away from the blade are advanced and guided into a receptacle. Thus, the manipulation of this apparatus is relatively complicated.
DE-OS No. 31 39 413 refers to a substantially improved automatic radish cutter. An electromotor is movable in a vertical guide and drives a cam for transmitting the rotary motion to a radish. Opposite to the cam is provided a threaded spindle on which the radish is vertically slipped. The cam is then superimposed on the upper end of the radish. Due to the driving via a cam, the radish is threaded on the threaded spindle and cut in the shape of spirals by a blade that stands radially with respect to the threaded spindle. Here the ascent of the threaded spindle determines the cutting gauge. If the radish is warped or has not been centrally slipped on the threaded spindle, disturbances in the operation of said radish cutter can of course occur. The radish then, after a few revolutions, ceases to be clamped between cam and blade. Thereby the motor with the cam suddenly sinks on the guide. This can result in damages to the cutting device, to the cam and to the threaded spindle. In addition, most of the time the radish can no longer be used.
The present invention is based on the problem of providing a cutting device of the kind in question that is of simple construction, easy to use, and whereby it is ensured that the item to be cut be firmly clamped during the cutting operation.
According to the present invention this problem is solved by the features stated in the characteristic part of claim 1.
Accordingly, the support for the item to be cut is provided with a funnel-shaped depression in the axis of rotation for the purpose of centering the item to be cut and with a recess for the blade, which recess starts from the passage point of the axis of rotation and extends substantially radially. The cutting edge of the blade at the same time projects above the tapered surface and defines an aperture through which the helically cut product can be discharged.
The item to be cut advances in the direction toward the blade by virtue of a weight such as the electromotor itself or a separate weight that holds the item to be cut with a cam so that the blade works into the item to be cut.
Here either the item to be cut can itself be rotated or the blade is rotated against the item that does not then rotate.
The distance by which the cutting edge of the blade projects above the tapered surface corresponds to the cutting gauge and thus to the advance per revolution.
The support, by virtue of its funnel-shaped construction, has an auto centering action for the item to be cut. In addition, the insertion of the item into the cutting device is substantially simpler since the item must be introduced into the funnel-shaped support only by one end and the other end must be connected with the weight. Hereby the item to be cut is pressed into the funnel and fed to the blade, which cuts the item in the form of a helical coil.
