Description

object The invention relates to a method and a device for continuous Cutting cheese strips.

The Invention is not limited to the cutting of cheese strips, with the goal, from the cheese bands corresponding cheese slices to cut, but it can without any problems, with cheese racks comparable materials, such as e.g. Tracks out Marzipan, from plasticine, chewing gum and the like. More.

So far it was not known, continuous cheese strips using a cutting wire to cut. It was only known, a continuously produced cheese tape in Transport direction (longitudinal direction) through mitlaufende, round knives to cut, or over longitudinal knife, which called a Guillotine cut performed.

One Disadvantage of cutting by means of the known, running knives is, that you in no time Pollute time and deal with the cut cheese particles accomplish, resulting in significant hygiene and cleaning problems led. The disadvantage of cutting by means of the mentioned guillotine knives is that these Knife can only cut to a relatively narrow limited length.

With the publication US 4,111,087 there is disclosed a cheese packaging apparatus having a cheese slicer which is operative when a cheese loaf is accurately positioned at an input position, the cheese slicer being adapted to function when a final assembly on which the sliced cheese is placed is accurate is positioned. The cheese slicer has a vertical harp and is adapted to carry out a vertical movement which moves the cheese loaf from a roll conveyor through the vertical harp and cuts the loaf. The rollers have a rotating inner part which causes an outer part to rotate when the torque between the two parts is below a certain size enclosed in the conveyor belt guide leading to the cutting device.

These Invention has the disadvantage that the cheese loaf is not on both sides of the Cutting device supplied and removed is and has a relatively high contamination of the cutting wires.

With the publication DE 298 01 163 U1 discloses a device for food comminution, which comprises at least one conveyor belt, which is guided around a driven roller and a guide roller, which are biased away from each other, wherein a roller arranged between the cylinder arrangement between a clamping and a release position is switchable.

This The invention is not apparent that the two arranged to each other Conveyor belts different Have conveyor speeds.

With the US 4,646,602 For example, there is disclosed a cheese slicer for crushing a block of cheese in three perpendicular directions, comprising a frame, a carriage mounted in a straight line within the frame, a stationary knife having a plurality of fixed cutting wires, such cutting wires extending across the region in which the carriage is moving, and a pivotable knife having a plurality of cutting wires fixed therein, pivotable through the travel area of the carriage, together with a quick changeable cutting wire attachment system and various security devices.

These The invention has the disadvantage that the cheese does not continuously feed the cutting wires dissipated can be.

Of the Invention is based on the object, a method and a after developing the device working so that it is possible, a sheet of cheese continuously in the longitudinal direction (Transport direction) in individual, adjacent cheese strips to cut and the cutting device relatively free of cheese particles to keep.

These The object is achieved by the in the independent ones claims specified characteristics solved.

essential Feature of the method according to the invention is that one continuously transported in the transport direction cheese web, which may also be multi-layered, by an approximately vertical Direction to the transport direction arranged cutting device is performed, which cutting device of one or more parallel to each other arranged Scheiddrähten consists.

With the given technical teaching so there is the significant advantage that you can now work in continuous (continuous) operation, ie the inventive method works continuously and takes over from the production machine there - possibly multi-layered - Cheese path and cuts the longitudinally into individual juxtaposed cheese strips.

advantage in the method according to the invention is that no Waste arises because the cutting wire used intersperses cheese tape and the upgrading of the cutting wire residues are again in Area of the dividing line downstream the cutting wire with the cheese strip united, so that the Material encloses the cutting wire, so to speak, and no cutting waste arises. Downstream of the Cutting wire, however, creates the desired separation cut (parting line).

advantageous Embodiments and development of the invention are specified in the dependent claims.

The used cutting device comprises one of several parallel arranged wires "cutting harp", wherein the individual cutting wires in parallel and at a mutual distance under spring tension individually are wound up on rolls. So that means the top and bottom End of each cutting wire is on a single, separately arranged Roll wound up and is curious that one or both roles under corresponding spring action in the pulling direction of the cutting wire respectively be biased against each other.

By The use of a variety of cutting wires can make very fine cheese strips be cut, as in a special training one Cheese bar arrangement be generated.

In a development of the method, it may be provided that the in dense distance adjacent cheese strips spread in the following which is achieved by a spreading device arranged after the cutting device becomes. This will take the cheese strips a greater distance one another and form spaces between them. This facilitates Handling the packaging of the individual cheese strips.

In a preferred embodiment of the process, a multilayer cheese web is cut, i. the sheet of cheese does not consist of a single layer, but there are several layers on top of each other arranged. The layers lie on each other without gaps and form such a multi-layer cheese strip, those with the inventive method now continuously in the transport direction (in the longitudinal direction) is cut. In this preferred embodiment, e.g. cut a 6-ply cheese strip, where two parallel cheese bars form by a dividing line (each conditioned by a cutting wire) from each other are separated.

To cutting the cheese strip longitudinal goes through the divided into individual cheese strips sheet of cheese a cross-cutting device, with the individual cheese bars defined length of the cheese railway cut and subsequently fed to a packaging machine.

Of the Users can now open the appropriate packaging for this cheese bar arrangement and the whole in pairs arranged cheese bars or only one or the other cheese jar. Every cheese bar then consists of layers one above the other arranged cheese strips, which can be consumed either individually or together immediately.

conditioned by the fact that no Waste when cutting the cheese strip arises, also accounts for corresponding cleaning operations on the cutting device. To have to only the transport rollers and the like at certain intervals getting cleaned. However, the cutting device itself is subject virtually no wear and tear does not pollute either.

A Apparatus for exercising of the method is preferably that one upstream of the Cutting device the cheese strip into the conveyor gap receives from two opposing conveyor belts, which conveyor belts accordingly the cheese strip of border on top and bottom and protect against posing and discarding. Both Conveyor belts (the upper and lower conveyor belt) to lead the cheese railway the subsequent cutter.

in this connection It is preferred, although at the outlet side of the cutter an identical conveyor belt arrangement, consisting of an upper and the lower conveyor belt is present, so that too the cut cheese strip in the conveying gap between taken up the upper and lower conveyor belt becomes.

The Use of an inlet-side and an outlet-side conveyor belt pair has the advantage that the Material web completely against revaluation, warping and discarding protected is and controls the at the end of the inlet side conveyor belt pair arranged cutting device is supplied.

In narrow distance behind the cutter then begins the outlet side arranged conveyor belt pair, which receives the cut strips and a spreader supplies.

This spreader consists essentially of a support table on which the closely spaced and by the respective separation cut separate double cheese bars are arranged side by side lying. The cheese bars are subsequently spread so that each a double cheese bar, formed from two adjacent by a distance separate bars.

in the The following is the invention with reference to only one embodiment illustrative drawings closer explained.

It demonstrate:

1 : schematized in perspective front view the representation of a Doppelkäseiegel;

2 : schematic side view of the cutting device with inlet and outlet side conveyor belt;

3 : the side view of the cutting device;

4 : the top view of the spreader;

5 : the side view of the spreading device;

6 : Schematisiert in plan view of the cutting process in the range of a cheese strip;

In 1 is schematized a sliced double cheese bar 1 illustrated how it is fed to a subsequent packaging machine. In the illustrated embodiment, the double cheese bar 1 from two adjacent cheese bars 2 . 3 , where the two cheese bars by a dividing line 5 (Separation cut) are separated, but stick together.

Every cheese bar 2 . 3 has an equal number of superimposed layers of cheese strips 4 on.

Once the double cheese bar 1 can be removed from a package in the form shown there, each cheese can 2 . 3 be separated from each other and either consumed in one piece, or it may also be from each cheese jar 2 . 3 the corresponding cheese strips 4 peeled and consumed individually.

The 1 indicates, moreover, with dashed lines that the web 6 ' from several adjacent double cheese bars 1 . 1' etc., as based on the 4 will be explained below.

In the following description, it is therefore assumed that a multilayered cheese web 6 is cut, as exemplified in 2 is shown. This multi-layer cheese strip 6 consisting of individual superimposed layers of cheese strips 4 is, is by means of a transport device in the arrow direction 7 the cutting device 15 fed and discharged again.

The cutting device 15 is in the space 19 between the inlet-side transport device 9 . 10 and the outlet side transport device 20 . 21 arranged.

Upstream and downstream of the cutter 15 If the transport device consists of a conveyor belt pair 9 . 10 , which consists of an upper 10 and a lower conveyor belt 9 consists. Each conveyor has a relatively larger upstream idler 12 , and a relatively smaller formed downstream and near the cutter 15 located pulley 13 , Between the pulleys 12 . 13 is a continuous, uninterrupted conveyor belt arranged, which z. B. from a coated textile material, a plastic material or the like. There is.

The downstream pulley 13 , next to the cutting device 15 is arranged, has a relatively small diameter to the two conveyor belt pairs 9 . 10 and 20 . 21 as close as possible to the cutting device 15 to be able to approach.

The multi-layered cheese railway 6 gets into the conveyor gap 8th between the two conveyor belts 9 . 10 recorded, each conveyor belt respectively in the conveying direction 11 is driven.

Advantageously, the conveying speed of the upper conveyor belt deviates 10 from the conveying speed of the lower conveyor belt 9 something off, what about the consistency of the multilayer cheese rink 6 depends. With a relatively hard material web, the upper conveyor belt runs 10 with about 1% higher speed than the lower conveyor belt. This leads to appropriate utilization of the material web in the conveying gap 8th can be avoided and the web completely flat and without distortion of the cutter 15 is supplied.

The contact force between the upper and lower conveyor belt 9 . 10 can otherwise by a piston-cylinder arrangement 14 be set, which, for example, the upper conveyor belt 10 against the lower conveyor belt 9 biases.

The material web, which the inlet side arranged conveyor belt pair 9 . 10 leaves, according to 3 now through the cutting device, gebil det by a series of preferably perpendicular to the conveyor belts arranged cutting wires 26 , through.

The cutting device comprises a plurality of mutually parallel cutting wires 26 and consists of a bearing plate 22 , which cross transverse struts 23 with a front bearing plate 24 connected is. At the front bearing plate 24 this is a handle 25 arranged. The entire cutter can therefore be retracted as an upright drawer in the arrangement and indeed in the space 19 between the two conveyor belts 9 . 10 respectively. 20 . 21 , It is therefore easily replaceable, because it can be pulled out like a drawer, if there is a disturbance in the field of cutting wires 26 comes.

Every cutting wire 26 is on two assigned roles 16 . 16a biased ( 2 ), where, for example, the upper roll 16 by means of spring force against the lower roller 16a in the direction of the arrow 17 is biased.

There may also be a breakage control for each cutting wire, for example in the upper roll 16 a mark 18 is present, whose rotation in the arrow direction 17 and in the opposite direction is monitored by a corresponding sensor. Tear a cutting wire, then the mark twists 18 for a certain way, for example in the direction of the arrow 17 and this is detected by the sensor and the assembly is shut down.

Otherwise, the cutting plane 47 , which by the parallel arrangement of the individual cutting wires 26 is formed in the arrow directions 45 be pivoted, so that the material web 6 the cutting device does not go through exactly at right angles. It can, for. B. the cutting plane are pivoted in the range of 90 ° by about 10 ° obliquely forward or backward; this depends on the speed of the material web and on the consistency of the material web.

In 6 is such a cutting process using a single cutting wire 26 shown. The cheese sheet, exemplified in the form of individual fibers for illustrative purposes, becomes the cutting wire 26 fed. The cut web flows around the cutting wire 26 and unites again - slightly together - in the area of a dividing line 5 , where no waste is produced during cutting.

For the downstream pair of conveyor belts 20 . 21 The same description applies as for the inlet-side conveyor belt pair 9 . 10 was given. Again, a corresponding piston-cylinder arrangement is present and the conveyor belts 20 . 21 may optionally be at different speeds in each case in the direction of arrows 11 are driven.

The aforementioned spreader 27 into which the multilayer, cut material web 6 ' enters, is in 4 shown in plan view. A cut and separated double cheese bar 1 is in 1 indicated. The spreader device makes the double cheese bars 1 . 1' each separated, ie there are always two cheese bars 2 . 3 in bond and by a dividing line 5 separated from each other, together and are also packed together.

According to 5 the spreading device comprises a support table 31 , starting from the down frame struts 43 are arranged, which in a transverse thereto extending bearing plate 44 at which end the engine is hanging 36 is arranged. The entire material web to be spread 6 ' lies on a variety of driven in the transport direction transport rollers 40 on. In 5 is shown that a motor 36 over his drive wheel 37 a drive belt 38 drives, the corresponding pulley 39 all transport roles 40 synchronously and simultaneously drives.

In 4 is the arrangement of two adjacent transport rollers 40 indicated by dashed lines, although a plurality of parallel transport rollers (eg, a number of 30 rollers) are juxtaposed over the entire spreading surface of the spreader 27 are arranged distributed.

The separation of the material web 6 ' in single double cheese bars 1 . 1' takes place in the region of the spreading edge 46 between the individual double cheese bars 1 . 1' ,

The spreading of the material web 6 ' takes place in accordance with 4 and 5 in that the individual Doppelkäseriegel 1 . 1' the cut material web laterally on boundary rollers 28 pass by, the limiting rollers are not driven.

The single double cheese bars 1 be downstream on pivot pins 32 . 33 passed, wherein the distance between the pivot pins now the final distance between the Doppelkäseiegeln 1 Are defined. Between the single double cheese bars 1 So results on the outlet side of the web 6 '' one space each 29 , The pivot pins 32 . 33 are rotatable on a retaining plate 41 held, which in turn by a piston-cylinder arrangement 42 raised and lowered in the direction of the material web 6 . 6 '' and in the opposite direction are movable.

In this case, the spreading is otherwise mirror-symmetrical with respect to a longitudinal center line 30 passing through the spreader 27 runs in the longitudinal direction.

After leaving the spreader 27 becomes the spread material web 6 '' by a cross cutter 34 passed, which from the individual Doppelkäseiegeln corresponding pieces of a length of z. B. 100 mm.

These cut pieces are fed to a packaging machine and packaged there in juxtaposed packages, so that in each packaging wrapper a Doppelkäseriegel 1 . 1' is available.
