Abstract

PURPOSE: To cut a product at a high speed in a low load by forming a cutter so that the periphery of the circumferential part continuously increases up to a maximum value by starting from a minimum value in the vicinity of a hub. CONSTITUTION: A cutter 3 is fixed to a driving shaft 1 through the hub part 2. A radius of this cutter 3 continuously increases on the periphery of the circumferential part up to a maximum value by starting from a minumum value in the vicinity of the hub part 2, so that various diameters related to this maximum cutter diameter and a minumum cutter diameter are arranged in a single radial plane. The cutter 3 is desirably composed of an elastically deformable metallic disc with a slender groove cut in the radial direction in a place of transferring to a minimum diameter from a maximum diameter. Therefore, when clamped by a clamping inclined face on the hub 2 according to a required offset of the cutter 3, the cutter 3 becomes the final shape, so that the cutting blade 4 expands in a spiral shape. A product passing through a product passing area 5 of the cutter 3 formed in this way, is cut at a high speed in a low load.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cutting device for food products, in particular for cutting sausages, hard sausages, smoked sausages, fatty meats, bacon, meat, cheese, etc. This invention relates to a cutting device and consists of a product feeding device having a guide path extending into the cutting surface and a rotatably driven knife which periodically passes through the cutting surface.

BACKGROUND OF THE INVENTION Sliced product cutting devices, also called "slicers", are generally known and consist essentially of a blade that rotates in the manner of a planetary wheel and makes a cut each time it passes a cutting surface. During cutting, the product feed is usually
Advancement of the product is carried out intermittently, ie at intervals between two successive cuts.

It is recognized that a high cutting sequence can be obtained with this type of slicer, however, ensuring trouble-free operation and as a result of the planetary rotation movement of the cutter
A relatively complex device construction is required in order to be able to absorb the considerable forces that occur during the cutting procedure.

OBJECT OF THE INVENTION The object of the invention is to provide a sliced product cutting device of the kind named in the opening, in which high-speed cutting is achieved with a low product load and at the same time forces generated in the cutting unit. can be lowered, which allows for relatively low equipment costs.
It is to be structured in such a way that it is possible to construct an uncomplicated device.

[Constitution of the Invention] This object is such that the cutter is fixedly attached to a drive shaft that is reliably supported in the device via a hub part, and the diameter of the drive shaft is equal to the continuous axis of the cutting blade. According to the present invention, the outer circumference increases continuously from the minimum value to the maximum value at the same time as the displacement in the direction, and the passing area of the product is determined by the difference between the maximum radius and the minimum radius of the cutter. It is achieved based on

As a result of the special layout of the cutter, it is possible to achieve high-speed cutting while continuously feeding the product, and thereby the cutter strikes the product in such a way that it strikes as in the case of a conventional slicer. Rather, the product is kept under very low loads, as it is effectively screwed in by itself, and thereby in a very uniform manner with each revolution. The purpose is to separate the slices that are It is important to note that this spiral cutting process does not create any rubbing stains on the product.

The cutter of this invention preferably has a structure similar to the disc-shaped cutter of a conventional slicer, and has a hollow "throat" on the back side adjacent to the cutting blade. During this process, virtually only the tip of the cutting blade comes into contact with the product. Through the matched layout of the blade shapes, cutting is effectively performed over an angle of at least 280°, which provides a sufficiently large product passage area. A particular slice thickness can be preset by the cutter blade set (cutting blade offset). The slice thickness depends on the product to be cut and ranges from 1.5 mm to 2.5 mm, for example.

The cutter used according to the invention has an elastically deformable flat disk and an inclined clamping surface that widens according to the required offset of the cutter for clamping the inner ring end of the cutter. It is particularly advantageous if the hub part has a clamping ramp.

As a result of this idea, it is possible to first create a cutting tool in the form of a flat disc, already with the required circumferential contour, and then machine the cutting edge area in a predetermined manner, since the cutting tool offset or axial displacement of the cutting blade to accommodate the spiral of the cutting blade,
As a result, the outer circumference is first obtained and then firmly preset by fixing this cutter on the correspondingly shaped slope of the hub part.

This embodiment simplifies the manufacture of the cutter provided according to the invention in a quite decisive way, and furthermore this embodiment does not pose any difficulties through the selection of the corresponding clamping ramps. This makes it possible to supply different cutter offsets without any problems. It also simplifies resharpening of the knife, since for the latter purpose, the knife can simply be removed from the hub and then resharpened in the flat position. By using the device of the present invention, “
As a result of "pull" cutting, it is always possible to obtain a clean cut surface without any rubbing dirt, and this is true even when cutting at high speeds and when cutting products that are prone to interlayer formation. is always obtained. Even if a defect appears on the cutter, it always appears in the same position based on the cutting principle, and this defect does not pose a danger in itself.

It is important that all the above-mentioned advantages are obtained with a device which has extremely simple constructional features and does not require excessively robust mechanical construction.

[Example] A cutter 3 is securely tightened and fixed to a drive shaft l. This cutter is fixedly supported on the machine side by a hub portion 2 that is relatively fixed to the shaft. There is. The knife 3 has a cutting blade 4 on its outer periphery, and on the back side, the periphery adjacent to the cutting blade has a hollow "throat shape" so that during the cutting process there is no cutting edge. Only blade 4 works effectively.

The radius of the cutting tool 3 starts from a minimum value near the hub and increases continuously around the circumference up to a maximum value, and the various diameters associated with the maximum cutting tool diameter and the minimum cutting tool diameter lie within one radial plane ( (at the 9 o'clock position in FIG. 1).

Preferably, the cutter is made from an elastically deformable metal disk cut with a radially elongated groove at the transition from the largest diameter to the smallest diameter. To this end, according to the required offset of the cutter 3, the cutter assumes its final shape when clamped onto the clamping ramp on the hub part 2, and the cutter is fixed in such a way that the cutting blades 4 are spread out in a helical manner.

Embodiments of the cutter of the present invention, despite the inherent complex and special shape of the cutter mounting condition, allow for a very simple manufacture of the cutter and, after removal of the cutter from the hub, a simple and quick installation. This makes it possible to resharpen the blade.

FIG. 2 shows further details of the mechanical arrangement. From the drawing it can be seen that the drive shaft l rotating in the direction of the arrow 6 in the figure is an axis projecting through the axial assembly of the inner clamping ramp 9, the cutter 3 and the outer clamping ramp 12. It has a fixed shoulder part 7 with a "dowel" 8 extending in the direction, so that these components are positively arranged in the circumferential direction. This assembly is Natsuto IO
This nut IO can be screwed onto the threaded part 11 at the end of the drive shaft. That is, the nut 10 clamps and tightens the inner and outer ramp and cutter assemblies against the annular shoulder portion 8.

Inner and outer clamping ramps 9 and 2 ramps 1
2 and 13 appear to be in the form of a spiral of exactly one revolution, and the offset 14 between the start and end of each ramp determines the thickness of the cut.

Figure 2 also illustrates the length of the hard sausage 15 supported on the guide 16, and this guide! 6 is 1
The limit of the guide passage extending in the direction of 7 is determined.

The guide 16 has a shoulder part (the shoulder part is not shown, but exists on the plane of the drawing), and this guide 16 has a movement that tries to fly out of the plane of FIG. In other words, the sausage 15 is held against the pores generated by the rotation of the cutter. The pusher plate 18 holds down the end of the sausage and also has a screw part 19, which screw part I9
meshes with a rotary drive ball inside the electric feed device 20 (this ball is not shown), so that the food product can be fed continuously along the guide 16 in the direction 17. It should be noted that the direction 17 forms an acute angle α with the axial direction 21 of the drive shaft l. This angle α
It is desirable that it be changed during use.

Finally, FIG. 3 shows the cutting blade 4 of the knife 3 and in particular the hollow "throat" 22 on the back side of the knife.

The choice of different disc thicknesses is advantageous in order to make the pitch of the fixed clamping ramp variable, so that the disc thickness can be changed in the current working procedure. be.

In this case, the adjustment takes place via the individual ramp parts, which are replaceable relative to each other and are connected to each other via control elements (not shown). There is.
