DE10102095A1 - Rotary slicing machine for fruit and vegetables comprises series of knives attached to rotary shaft, draw-cutting slices cleanly at differing depths from even soft fruit - Google Patents

Abstract

The knives (1) are attached to the shaft (2) for rotary movement when cutting the fruit (3).

Description

It is known to slice fruit and vegetables by means of punches, turntables with 1 or more knives, Planing, pass-through grids.

All of these devices have a second operation necessary to do this in a separate step beforehand peeled and pitted fruit in slices to cut. These immediately fall apart and change color through atmospheric oxygen and environmental influences.

There is no pulling cut when punching and throwing through reached, the cut surfaces do not become smooth and brown fast.

With all techniques, the fruit is not centered and can turn around. The slices are unevenly thick and the core hole is not in the middle. The work is done by hand dangerous, the machines complex and expensive. Short fruit is difficult to edit.

Devices such. B. Utility model G 88 05 763.1 A 23 N shows a technique which produces a fruit spiral must be divided into slices to make the Disks are not closed.  

The invention specified in protection claim 1 is Problem to avoid additional operations, to increase the cut quality and slice quality of the fruit to protect against tanning, to increase the variety of products.

This problem is solved by the in claim 1 listed features solved.

The advantages achieved with the invention exist especially in that by the rotating or pushing movement the knife the rotating fruit at the same time with others Processing steps such as B. peeling can be processed. There is no need for a second operation, which saves not only time, but increases hygiene since the fruit after not peeling must also be touched and not the discs fall apart. Due to the small surface area up to a lower germ load for further processing and browning of the panes is avoided.

By holding / driving the fruit in the core join crunchy fruit no impressions.

By moving the knives, very thin ones can also be made Cut slices because there are only a few knives at a time in the fruit and the clamping pressure are low. By moving the knife will achieve better power transmission there the slice lying further to the fruit intake still is cut less deeply than the more distant one.

The training according to claim 2 saves that sorting out clippings that are too long. With longer knives at the outer end of a knife set is for the machine cut clippings that are too long can fall off without them Clogging machine.

The training according to claim 3 enables easiest white the cutting thickness by changing tools to change.

The training according to claim 4 enables both the attachment to different types of machines, and makes it possible the user to adjust how easily the cut Have the disks separated.

The training according to claim 5 allows continuously working machines swiveling the next clippings.  

The training according to claim 6 prevents Wrap shells in the knife set.

The training according to claim 7 enables cultivation the device to any machine by the operator without electrical modifications and time-consuming Safety measures. In comparison to operating one Disc cutter with separate motor no complex Position queries and stepper motors necessary.

An embodiment is shown in the drawing and described in more detail below.

Show it:

Sketch 1 a disc cutting device with rotatable arranged knives.

Sketch 2 shows a disc cutter with a straight line movable knives.

Sketch 3 is a side view of the disk cutting device coupled with a belt drive, for example with the eccentric drive of the peeling knife.

The fruit ( 1 ) is cut by the knives ( 3 ) during a rotating movement of the fruit (e.g. peeling drive) up to the fruit intake ( 4 ). Here a knife ( 2 ) cuts through which is longer before the fruit intake.

The knives can be fed ( 5 ) in a straight line (sketch 2) or in a round line (sketch 1). The knives cut the fruit one after the other from the side facing away from the fruit intake, so that the cutting force is not only transferred from the center piece (slug) but is also transferred directly from the fruit intake via the slices, which are still less deeply cut (sketch 3), the fruit does not break off.

Sketch 3 shows a simple solution for driving the knife set z. B. via toothed belt ( 6 ) from an existing eccentric disc ( 7 ).

A height adjustment option for the knives ( 8 ) ensures that the knife set is compatible with different machines and that the discs hold together even more if desired.

The slices are only separated after the slice ( 9 ) has been cut out, but remain stuck together due to the juice and do not tan.

When there is a gap in the knife set ( 10 ), the next apple in automatic machines can swivel into the working plane.

By resetting the knife set against the cutting direction ( 5 ), the back and forth movement ensures that no peels can wrap around the knives in peeling machines. This is also due to the coupling z. B. achieved by toothed belt ( 6 ).
