Abstract

In order not to adversely affect the interlayer belt (100) during feeding in the case of portions (P) with an interleaf (101) between the individual slices (S), it is driven according to the invention by transport elements (32.1, 32.2) which, with a large Contact surface on the interlayer tape (100).

Description

field of use

The invention relates to so-called slicers, with which strands or sticks of an only slightly compressible product such as sausage or cheese are cut into slices very quickly in the food industry, typically with a time interval of less than 0.3 seconds between the cutting processes.

Technical background

Since these strands can be produced with a cross-section that is dimensionally stable and dimensionally stable over their length, that is to say essentially constant, they are called product calibres.

In this case, several product sizes lying next to one another are usually cut open at the same time, in that the same knife, which moves in a transverse direction to the longitudinal direction of the product size, cuts off a slice from each product size during a separation process.

The product calibres are pushed forward by a feed conveyor in the direction of the knife, for which the feed conveyor is usually directed downwards at an angle, and each guided through the product openings of a so-called cutting goggle, at the front end of which the protruding part of the product caliber is located is separated from the knife as a disc immediately in front of the cutting glasses.

As a rule, the slices fall onto a conveyor, by means of which they are transported away for further processing.

Often, individual slices should not be transported away on the conveyor, but rather several, at least partially overlapping slices as a portion, e.g. partially overlapping in the form of a so-called shingled portion or completely overlapping in the form of a stack of aligned slices, which is why this is usually the case designed as a conveyor belt discharge conveyor is then often called a positioning belt.

Since, depending on the type of product, slices stick together so tightly, e.g. with cheese, that they cannot be detached from each other without being damaged, an intermediate layer, the interleaver, is automatically created from a sheet of paper when placed between two slices or foil inserted automatically in between.

For this purpose, an interlayer tape coming from below is fed with the free front end through a narrow slot in front of the lower edge of the through opening of the cutting glasses until the free front end of the interlayer tape is at or above the upper edge of the through opening and then the front end Area separated as an interlayer sheet.

This can be done together with the cutting of the next slice and by the same knife, or separately by a special interlayer knife, in particular before or while the product size is pushed forward through the cutting glasses for the cutting of the next slice.

The interlayer sheet then falls together with the next severed slice onto the previous slice already on the portioning belt.

The interlayer tape is usually transported in that several transport units are arranged one behind the other in its transport direction between the supply roll and the ejection point.

It is for example from the WO 03/037578 A1 known that the last transport unit in the transport direction before the ejection point consists only of two counteracting, drivable transport rollers that clamp the stationary interlayer tape between them immediately before the slot after each disc has been separated and accelerate and very quickly have to eject from the slot, which is why the intermediate layer tape usually also forms a buffer loop between this last transport unit and the supply roll.

However, the strong acceleration of the interlayer belt from standstill by such a pair of transport rollers often leads to damage or deformation of the interlayer, for example to streaks in the film in the case of a transparent film as an intermediate layer.

Further upstream on the intermediate layer belt, a transport unit consisting of two transport belts acting against one another is also known, since there are no cramped spaces there, as the cited document shows.

It is also from the DE 102011103447 A1 already known to design the last transport unit in the form of a transport belt, which holds the interlayer belt against a fixed, stationary counter bearing and transports it, but this is due to the sliding friction then existing between the interlayer belt and the stationary Counter-bearing also carries the risk of damage to the interlayer tape.

Presentation of the invention

Technical task

It is therefore the object of the invention to create a slicer and, in particular, an intermediate layer unit for this purpose, as well as a method that can be used in this connection, with which this problem is minimized or completely eliminated.

Solution of the task

This object is achieved by the features of claims 1 and 10. Advantageous embodiments emerge from the subclaims.

With regard to the slicer, the problem of introducing an intermediate layer between the deposited slices of a portion is solved in that the intermediate layer drive for driving the intermediate layer belt as the last drive unit in the feed direction comprises a pair of transport elements moving with the intermediate layer belt, which on are arranged opposite sides of the interlayer tape and hold the tape between them and take them.

The essential thing here is that these two transport elements rest against the intermediate layer belt with a large contact area. In contrast to two transport rollers, of which at least one is driven and which clamp and transport the interlayer tape between them and in which there is a theoretically only linear contact surface along the respective surface line of the transport roller, which is of course due to the material elasticity of the surface of the transport roller as well as the resilience of the interlayer tape, albeit very thin, is actually strip-shaped, but still represents a very small contact area.

A large contact area is therefore understood to mean that it is at least 1 cm long in the feed direction of the interlayer tape, better at least 2 cm, better at least 3 cm long. The contact surface preferably extends over the entire width of the intermediate layer tape, but at least over at least 30% of its width, better at least 50% of its width, better at least 80% of its width.

The contact area preferably has a size of at least 15%, better at least 30%, better at least 50%, better at least 70% of the area of an interlayer sheet to be separated from the interlayer tape.

Due to this large contact surface, the contact pressure between the contact surface and the interlayer tape can be kept relatively low for a force-fit entrainment of the interlayer tape through the contact surface Deformation such as folds in the interlayer tape occurs, much less than with the much smaller transport surfaces that have been customary up to now.

The large contact surfaces are preferably implemented with the help of two endless, revolving conveyor belts, each arranged on one side of the interlayer belt, as transport elements, which are driven synchronously in the strand adjacent to the conveyor belt and the interlayer belt to be transported Hold it clamped between you and transport it synchronously with this respective strand, i.e. by means of a force-fit system.

Each of the two endless conveyor belts is guided over at least two belt rollers, one of which is arranged in the feed direction near the free end of the interlayer belt, in particular near the slot through which the interlayer belt exits with its free end, while the other belt roller is further spaced therefrom. The two belt rollers remote from the slot or from the end are preferably the driven rollers and are in particular driven by the same motor, since there is less space there than on the front belt rollers. There is thus sufficient space for a mechanical coupling of the belt rollers, and these driven belt rollers can also have a relatively large diameter.

For the same reason, the front, near-end or near-slot belt rollers can have a smaller effective diameter with which they rest on the conveyor belt than the other two belt rollers.

The conveyor belts on the side facing the intermediate layer belt are preferably made of a material with high static friction, such as silicone, in order to avoid slippage.

The intermediate layer drive is preferably designed so that the conveyor belts can be pulled off the belt rollers quickly and easily, preferably without tools and in less than 30 seconds, for example by the known pivoting of the front and / or rear belt rollers to a lower level mutual distance, so that the conveyor belt is then easily pulled off in the axial direction of the belt rollers can be. This makes it easier to clean and replace the conveyor belts.

Instead of always moving contact surfaces in the same direction, the feed direction, solutions with contact surfaces moving in an oscillating manner are also implemented using finite transport plates as transport elements.

Such transport plates can be moved back and forth in the feed direction, and transversely to the plane of the interlayer tape away from this and towards this up to the clamping of the interlayer tape between the transport plates, these movements preferably always synchronous with respect to the both transport plates.

In the clamped state of the interlayer belt, i.e. transport plates with force against each other with the interlayer belt in between, these are moved synchronously in the feed direction, then lift off the interlayer belt and move back by the same step length in the lifted state, to be placed again against the interlayer tape, etc.

Here, too, the transport plates are preferably easily and quickly detachable from the plate drive, usually a lever linkage with a connecting rod, attached for cleaning and replacement purposes.

Here, too, both transport plates are preferably driven jointly by the same motor by means of a corresponding gearbox, on the one hand to keep the structural effort within limits and, above all, to avoid electrical synchronization of two drive motors, which can be solved mechanically more reliably.

With regard to the method for inserting an intermediate layer in a slicer between the slices of a portion, the existing object is achieved in that the intermediate layer belt from the last or only drive unit in the feed direction over a large area between two transport elements running with the intermediate layer belt, in particular frictionally , is held, in particular by means of transport elements and contact surfaces with dimensions as described above.

the 1a , 1b show different perspective views of a slicer 1 for cutting several product sizes at the same time K side by side and filing in shingled portions P. from several slices each S. with a general direction of travel 10 * through the slicer 1 right to left as well 1c a side view of this slicer 1 .

1d shows a vertical section through such a slicer - simplified by omitting details that are less important for the invention 1 longitudinal 10 , the direction in which the caliber is fed K to the cutting unit 7th and thus the longitudinal direction the one in the slicer 1 lying caliber K , so with the same viewing direction as 1c .

It can be seen that the basic structure of a slicer 1 according to the prior art is that a cutting unit 7th with a rotating sickle knife 3 several, in this case four, across the feed direction 10 adjacent product caliber K from a feed unit 20th are fed from the front ends of the rotating sickle knife 3 one disc at a time S. separates.

For this purpose, the feed unit includes 20th a feeder 4th in the form of an endless, revolving feed belt 4th , whose upper run at least in the feed direction 10 as well as being drivable against this, the width of this feed conveyor 4th adjacent calibers K sometimes not on the infeed belt 4th rest themselves, but on crossbars 15th across the width of the infeed conveyor 4th running and in the feed direction 10 spaced on the infeed belt 4th are arranged and the upper sides of the support surface 15 'for the individual calibers K represent.

The tops of the cross bars 15th have mutually aligned elevations with depressions in between for each of the calibers to be placed K , in this case four to ensure adequate lateral guidance.

The caliber K can also be placed directly on top of the feeder 4th rest by the elevations protruding upwards from this upper side as a lateral guide for the caliber, without the transverse webs 15th are present or in any case without them over the top of the feeder 4th protrude.

A height sensor can be used 19th the height, i.e. thickness, of the individual product caliber K in the second transverse direction 12th , i.e. perpendicular to the support surface of the feed belt 4th , measures, which is relevant for an automated control of the cutting and depositing process.

For cutting the product caliber K is the feeder 4th in the in the 1a - e shown inclined position with the low-lying cutting-side, front end and high, rear end, from which it is about one in its width direction, the first transverse direction 11 , extending pivot axis 20 ', which is located in the vicinity of the cutting unit 7th is located, can be folded down into an approximately horizontal loading position.

The rear end of one in the feed unit 20th lying caliber K - see in 1d the first caliber K1 of the four calibers lying one behind the other in this viewing direction - is each from a gripper 14a - d form-fitting with the help of gripper claws 16 held. This with regard to the position of the gripper claws 16 activatable and deactivatable gripper 14a - 14d are on a common gripper unit 13th attached, which along a rod-shaped gripper guide 18th in the feed direction 10 can be tracked.

• Denn für das Aufschneiden werden die vorderen Enden der Kaliber K jeweils durch eine für jedes Kaliber vorhandene sogenannte Brillenöffnung 6a - d geführt, die in einer plattenförmigen Schneidbrille 5 ausgebildet sind, die Bestandteil der Schneideinheit 7 ist, indem unmittelbar vor der vorderen, schräg nach unten weisenden Stirnfläche der Schneidbrille 5 die Schneidebene 3" verläuft, in der das Sichelmesser 3 mit seiner Schneidkante 3a rotiert und damit den Überstand der Kaliber K aus der Schneidbrille 5 als Scheibe S abtrennt. Die Schneidebene 3" verläuft lotrecht zum Obertrum des Zuförderers 4 und/oder wird von den beiden Querrichtungen 11, 12 aufgespannt.

Both the feed of the gripper unit 13th as well as the feeder 4th controllable drivable, but the specific feed speed of the caliber K by a so-called upper and lower product guide 8th , 9 is effected on the top and bottom of the caliber to be sliced K at their front end regions near the cutting unit 7th attack:

• Because the front ends of the caliber K each through a so-called eyeglass opening available for each caliber 6a - d out that in a plate-shaped cutting glasses 5 are formed, which are part of the cutting unit 7th is by placing immediately in front of the front, obliquely downward-facing end face of the cutting glasses 5 the cutting plane 3 " runs in which the sickle knife 3 with its cutting edge 3a rotates and thus the excess of the caliber K out of the cutting glasses 5 as a disc S. separates. The cutting plane 3 " runs perpendicular to the upper run of the feeder 4th and / or is from the two transverse directions 11 , 12th stretched.

The inner circumference of the eyeglass openings is used here 6a - d the cutting edge 3a of the knife 3 as a shearbar.

The glasses openings 6a - d the interchangeable cutting glasses 5 are about the cross-sectional shape and size of the caliber to be cut K adapted, since their cross-sectional size is subject to production-related fluctuations, the cross-section of the glasses openings is 6a - d usually slightly larger than the cross-section of the caliber to be cut K .

In order to still achieve a good cutting result, and parameters such as the tracking force of the caliber K on the inner peripheral surface of the eyeglass opening 6a - Being able to control d and other parameters is the lower as well as the upper, each designed as a conveyor belt, product guidance 8th , 9 present, of which the lower product guide 9 with its upper run and the upper product guide 8th with the lower run of the corresponding conveyor belt on the bottom or top of the caliber K fit firmly.

As both product guides 8th , 9 can be driven in a controlled manner, in particular independently from each other, they determine the - continuous or clocked - feed speed of the calibres K through the cutting glasses 5 . Preferably the two product guides are 8th , 9 in the first transverse direction 11 separately for each caliber K available and controllable.

In addition, there is at least the upper product guide 8th in the second transverse direction 12th - the perpendicular to the surface of the upper run of the feeder folded up into the slicing position 4th runs - can be moved to adjust to the height H of the caliber K in this direction. Furthermore, at least one of the product tours 8th , 9 around one of their pulleys 8a , 8b , 9a , 9b be designed to be pivotable to the direction of the caliber K to be able to change adjacent dreams of their conveyor belt to a limited extent.

The corresponding to the inclination of the feed unit 20th and cutting unit 7th Panes that are inclined in the room when separated S. fall on one below the cutting glasses 5 beginning and in the direction of passage 10 * running discharge unit 17th which in this case out in the direction of passage 10 * several with their upper strands approximately aligned one behind the other discharge conveyors 17a , b , c exists, one of which can also be designed as a weighing unit.

Below the feed unit 20th there is also an approximately horizontally running residue conveyor 21 also in the form of an endlessly revolving conveyor belt, the front end of which is below the cutting glasses 5 and immediately below or behind the discharge unit 17th begins and with its upper run leftovers falling on it from there against the direction of flow 10 * transported to the rear.

For this purpose, at least the one in the direction of passage 10 * first conveyor 17a with its upper run opposite to the direction of travel 10 * be driven so that any remaining piece, for example, that falls on it can be transported to the rear and onto the lower-lying leftover conveyor 21 falls.

After being cut, the panes fall S. either directly to this conveyor 17a-c , as in 1d shown, or on a packaging element resting on it V like a cardboard carrier or a flat plastic tray, as in the enlarged view of the 1e evident.

1e shows, on the one hand, that the lower end of the disc when it is cut off S. after detaching from the caliber K essentially without movement in the direction of passage 10 * falls vertically down, and the top of the disc S. - which is separated in time beforehand, thereby making an arc around the lower end, the disc S. so tilts down and if possible should be in an approximately horizontal, level position when it is on the discharge unit 17th hits.

If slices S. not individually and in the direction of passage 10 * spaced from each other on the discharge unit 17th but fall as shown by appropriate control of the discharge unit 17th servings there P. form in which the disks S. touch, for example stacked or the in 1e and 2 , 3 Shingled portions shown P. , it is known in the case of strongly adhering materials of the product caliber K automatically one interleaf each time 101 between the individual panes S. of the portions P. to lay, for which a layer pad unit 30th to slicers 1 is available.

The interlayer unit 30th initially includes a supply spool 39 from which the liner tape 100 is peeled off from the individual interleaves 101 can be separated for intermediate insertion.

To this end, according to 1e the liner tape 100 through a slot 35 in the cutting glasses 5 out, which are each just below the corresponding glasses opening 6a to d, as in 1g shown, and which extends at least over the entire length in the 1st transverse direction 11 measured width of the glasses opening 6a to 6d each extends, and - just like the interlayer tape 100 - is preferably wider in this direction than the product caliber K .

The slot can either be a straight slot 35 can be - as shown in the left half - or a curved slot - as shown in the right half - regardless of whether the glasses opening 6a - d is curved in the lower part - as with the outer eyeglass openings 6a , b shown - or a rectangular spectacle opening with a straight lower edge - as shown in the case of the spectacle openings 6b, c - because the curvature of the slot 35 and thus the interlayer tape to be fed through it 100 should the tape 100 stabilize due to the curvature transversely to its direction.

The slot 35 preferably does not run in the feed direction 10 , but at an angle to this, so with a side view of the 1e, f Inclination between the feed direction 10 and the 2nd cross direction 12th so that the front end of the interlayer tape 100 horizontally or diagonally upwards out of the slot 35 exits and is in front of the downward facing front of the next disc to be separated S. pushes.

It is approached or even applied to this by the air flow from a compressed air nozzle 40 who are in front of the cutting glasses 5 and usually a little below the slit 35 is located, and the air flow against the underside of the front end region of the interlayer tape 100 is directed so that the interlayer tape 100 preferably already during the cutting process of the pane S. on the downward facing front side.

After the knife 3 the disc S. completely of the caliber K has separated, it moves a little further down to over the slot 35 out, and thereby separates from the interlayer tape 100 the front end area as an interleaf 101 from which by the on the discharge unit 17th falling disc S. with is pressed down on the portions P. and there between two successive discs S. comes to rest.

According to 1f can feed the interlayer tape 100 instead of through a slot 35 also below the lower end of the cutting glasses 5 take place, but then there is no abutment for separating the interleaf 101 through the knife 3 .

As the interlayer tape 100 when cutting off an interleaf 101 The interlayer tape must not be pushed forward 100 between the individual separation processes are always accelerated and decelerated very quickly, which is achieved by the interlayer drive 31 takes place, which in known solutions according to the 1e , 1f from a pair of transport rollers 32.1 , 32.2 consists, which are driven in a controlled manner and between them the interlayer belt 100 Hold clamped and in the feed direction 31 ' also shortly thereafter the following slot 35 or the cutting glasses 5 support financially.

Due to the small contact area of these two transport rollers 32.1 , 32.2 and the high acceleration, however, can easily lead to folds or stretching and streaking of the interlayer tape, which is often made of a transparent plastic film 100 come.

the 2a, b show - in 2a with slot 35 , in 2 B with feed below the cutting glasses 5 - one across from the 1e, f first solution according to the invention, in which the contact surface 32a of the transport element compared to the transported interlayer tape 100 is enlarged in that it is a pair of both sides of the interlayer tape 100 adjacent conveyor belts 32.1 , 32.2 acts.

Due to the larger contact area 32a , so greater length of the contact area 32a in the feed direction 31 ' is the risk of damage to the interlayer tape 100 significantly less when accelerating.

The transport elements, here the conveyor belts, are also used in this solution 32.1 , 32.2 , as close as possible to the slot 35 positioned to avoid warpage of the liner tape 100 to avoid in between.

The belt rollers close to the slot are used for this purpose 33.1 over which the respective conveyor belt 32.1 , 32.2 running around, equipped with the smallest possible diameter.

According to the invention, the slot-remote belt rollers 33.2 on the other hand, with a significantly larger, ideally at least twice, diameter selected, whereby the contact surface 32a this belt roller 33.2 compared to the interlayer tape 100 gets bigger. This plays in spite of the conveyor belt in between 32.1 , 32.2 a positive role, because the greatest contact pressure on the interlayer tape 100 lies in the area of the belt rollers 33.1 , 33.2 before, while in the area in between the contact force of the conveyor belt 32.1 , 32.2 compared to the interlayer tape 100 is always a little lower.

the 3a, b show - in 3a with slot 35 , in 3b with feed below the cutting glasses 5 - one across from the 1e, f second solution according to the invention, in which the contact surface 32a of the transport element compared to the transported interlayer tape 100 is enlarged in that the transport elements are a pair of transport plates 34.1 , 34.2 , acts that the liner tape 100 Transport it forward step by step by placing the interlayer tape in a clamping position 100 keep clamped between you and with you in the feed direction 31 ' take with you firmly.

Then lift the transport plates 34.1 , 34.2 from the liner tape 100 move against the feed direction 31 ' backwards and begin the next transport step by completing the same closed orbit again.

For this purpose, the transport plates 34.1 , 34.2 for example, as shown, in each case by a lever mechanism 37 driven, which has a crank and a connecting rod attached to it 38 includes, the other end with the corresponding transport plates 34.1 , 34.2 is articulated.

The transport plates 34.1 , 34.2 can be guided in their orbit by means of link guides, or the lever mechanism 37 includes - which is not shown - instead of a single connecting rod 38 per transport plate 34.1 , 34.2 two spaced connecting rods 38 so that the transport plate 34.1 , 34.2 is guided in its orbit by a parallelogram square, the transport plate 34.1 , 34.2 always in a layer parallel to the interlayer tape 100 lies.
