Abstract

A product caliber (K) can be cut up to a remnant piece (KR) until either there is no longer a complete cross-section of the product caliber (K) and / or in the case of a product that is held in a form-fitting manner by means of gripper claws (16). Caliber (K) there is a risk of the knife (3) colliding with the gripper claws (16), because after deactivating the gripper (14), in particular the loosening of the gripper claws (16) from the remnant (KR), sometimes the remnant (KR) nevertheless remains adhering to the base body (14.1) of the gripper (14) and does not fall down as planned immediately after deactivating the gripper (14), according to the invention the remaining piece (KR) is released from the deactivated gripper (14) by means of a form fit is pushed away from the gripper (14) by a separate push-off ram (25).

Description

I. Field of application

The invention relates to slicing machines, in particular so-called slicers, with which strands of an only slightly compressible product such as sausage or cheese are cut into slices in the food industry.

II. 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 calibres are usually cut open next to one another at the same time by cutting off a slice in one pass from the same knife, which moves in a transverse direction to the longitudinal direction of the product caliber.

The product calibres are pushed forward by a feed conveyor in the direction of the knife, usually on a downwardly inclined feed conveyor, 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 from the knife is cut off 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.

During the slicing, the product calibres are mostly held by a gripper at their rear end facing away from the cutting goggles in a non-positive or positive manner, which for this purpose is provided, for example, with corresponding gripper claws that can be retracted into the caliber transversely to the feed direction.

After the one or more product calibres have been cut from an initial length to a minimum final length, before reloading the slicer with new product calibres it is first necessary to remove the remaining pieces on the grippers after cutting.

In principle, it can be sufficient to open the gripper so that the claws of the gripper holding the remainder of the product caliber releases the remainder. However, if the product caliber is the initially mentioned food such as sausage or cheese, it can happen that the remnant piece sticks to the base body of the gripper even after the claws have been opened.

To counter this problem, repelling devices have already been proposed in the prior art, in which the remnant piece is removed from the gripper by means of a pusher. If such a push-off device is, for example, a pneumatically actuated push-off device, a corresponding pneumatic cylinder must be provided on the gripper for this purpose, which requires a complex design of the gripper.

Furthermore, such pneumatic cylinders, as additional moving parts, represent an additional risk of failure and must be maintained with care, since even the smallest amounts of lubricant escaping from the pneumatic cylinder or unclean, in particular oiled, compressed air can contaminate the food to be processed.

III. Presentation of the invention

a) Technical task

It is therefore the object of the invention to provide a method and a slicing machine, in particular a slicer, which enables a remnant piece of a product caliber to be easily removed from a gripper and thereby has a high level of process reliability.

b) Solution of the task

This object is achieved by the features of claims 1 and 9. Advantageous embodiments emerge from the subclaims.

With regard to the procedure for detaching a remnant piece from a gripper after a product caliber has been cut open, this object is achieved in that the remnant piece still adhering to the gripper is moved backwards from the deactivated, i.e. in particular opened, and with the remnant piece in a direction opposite to the feed direction Gripper is pushed away in a direction transverse to the feed direction and detached.

This active and in particular form-fitting pushing away the remnant piece is reliably removed from the gripper, and if this takes place while the gripper is moving backwards, there is no loss of time that reduces the efficiency of the slicing machine.

If the pushing away in the direction of a support plane takes place on which the at least one If the product caliber rests during the slicing, in particular perpendicular to the support plane in the so-called second transverse direction, the remnant piece is accelerated in a defined manner in the direction in which it can fall, so that the impact area in which the remnant piece is supposed to hit is relative is small, which makes further handling easier.

The remnant piece is preferably only actively detached from the gripper when the gripper, in particular including the caliber remainder piece, is so far back measured in the feed direction that the falling remnant piece is no longer with the product guide that guides the product caliber during the slicing , can collide or can fall on the product guide, because this would require a subsequent removal of the remaining piece from the product guide and thus a separate work step.

The release position of the gripper is preferably located behind the rear end of the product guide, in particular behind the rear end of the lower product guide, in order to ensure this.

The remnant piece is preferably pushed away when the gripper is stationary, giving the gripper a defined release position in the feed direction, which facilitates the exact positioning and effective direction of a push-off device by means of which the pushing away is carried out.

The movements of such a push-off device, in particular its movement or pivoting, are preferably carried out independently of the movements of other components of the slicing machine, in particular independently of the movement of their product guide, so that these components move in a high manner Efficiency of the machine can perform at any point in time and preferably independently of the time of the movements of the push-off device.

To remove the remnant from the machine, the remnant loosened by the gripper is dropped onto a discharge device, in particular a remnant conveyor or a remnant chute, so that it no longer hampers further operations within the slicing machine.

Either the remnant piece is dropped directly onto the discharge device, which means that in particular the discharge device is arranged above the feed conveyor for the product sizes to be cut, or the leftover piece is dropped past the front end of the feed conveyor onto a discharge device arranged below, for which purpose if necessary first a gap has to be created between the front end of the feed conveyor and the product guide, for example by pivoting up the lower product guide.

This is the fastest way to remove the remaining pieces from the slicing machine.

The remainder can, however, first of all also be dropped onto the feed conveyor and then the latter can be driven in such a way that the remainder is thrown over its end onto the discharge device arranged below.

This takes longer, but gives greater freedom with regard to the detachment position of the gripper in the feed direction.

With regard to the slicing machine, in particular a slicer, this includes generic components, namely on the one hand a cutting unit with an in particular rotating, plate-shaped knife, usually a sickle knife, and on the other hand a feed unit for feeding the at least one, mostly several side by side in the first transverse direction lying, product calibers with their front ends to the cutting unit.

In this case, the feed unit comprises, on the one hand, one gripper for each product caliber, which holds the product caliber at its rear end, preferably in a form-fitting manner, for example by having gripper claws that are movable, in particular pivotable, relative to the base body of the gripper and that are used to activate of the gripper into the rear end of the product caliber can be pivoted into their activated position.

The feed unit can furthermore have a product guide at the front end, i.e. near the cutting unit - in particular immediately behind the back of a pair of cutting glasses, through whose at least one glasses opening the caliber to be cut is passed - usually consisting of an upper and lower product guide, which are located on the top or bottom . The underside of the product caliber is in contact.

The product guides are preferably in each case endless guide belts rotating around two deflecting rollers, which can be driven at least synchronously with one another, in particular can be driven independently of one another.

At least one of the product guides, in particular guide belts, preferably both, can be displaceable in the direction of the second transverse direction, in particular independently of one another.

The lower product guide, in particular the lower guide belt, is preferably pivotable about a pivot axis running in the first transverse direction, so that the lower product guide can be pivoted into the path of movement of the caliber and can also serve as a stop for the front end of a product caliber, which then - in the case of a guide belt as a product guide - presses against the contact strand of the guide belt with its end face.

The existing object is achieved with regard to the slicing machine according to the invention in that the machine has a push-off device for, in particular form-fitting, pushing away the remnant piece from the gripper and the control of the machine is designed and able to carry out the method described above.

The push-off device is preferably arranged above the support plane on which the at least one product caliber rests when it is sliced. The deactivated push-off device does not interfere with the slicing process, at least if the deactivated push-off device is located outside the path of movement of the product gauges and the feed unit during slicing.

The push-off device preferably comprises a push-off ram which can be moved transversely, in particular orthogonally, in the direction of the support plane and away from it and / or around a pivot axis running particularly transversely, in particular orthogonally, to the feed direction. This can be achieved through very simple mechanical constructions.

The push-off ram can preferably be moved in a controlled manner independently of the product guidance, which enables greater freedom of design in the sequence of movements of the individual components of the machine.

The push-off ram can, however, also be attached to the product guide and can only be moved together with it, which does not offer this advantage, but represents a very simple drive for the push-off ram.

The removal device is in particular a remnant conveyor or a remnant chute, which is arranged and dimensioned so that it can quickly remove remnants released by the gripper from the slicing machine in order not to delay the slicing of the next caliber.

The discharge device can be arranged above the feed conveyor and protrude into the area vertically under the push-off device, in particular under the extended front end of the push-off ram. Then the force of gravity can be used to transport the remnant piece to the discharge device and it is avoided that the remnant piece reaches the feed conveyor and has to be removed from it first.

The discharge device can, however, also be arranged below the feed conveyor and protrude into the area vertically below the front end of the feed conveyor in order to discard residual pieces that have fallen onto the feed conveyor via its front end onto the discharge device.

This has the advantage that no discharge device has to be provided above the feed conveyor, which then must not collide with the feed conveyor in the folded-up cutting position. This can make it difficult to transport the residual pieces to the rear end of the machine and possibly force them to be transported away in the transverse direction, that is to say to one of the sides of the machine - viewed in the feed direction.

Embodiments according to the invention are described in more detail below by way of example. Show it:

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 placing in shingled portions P each made of several slices S. with a general horizontal flow direction 10 * of the food to be sliced through the slicer 1 from right to left. 1c shows a side view of this slicer 1 .

2a 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 of 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 comprises 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 tops of the four bearing surfaces 15 ' for each caliber K represent, of which one can only be partially seen in the perspective views.

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 - c as 2a shown inclined position with the low-lying cutting-side, front end and high, rear end - the slicing position - from which it is about one in its width direction, the first transverse direction 11 , running swivel axis 4 ' that are near the cutting unit 7th can be folded down into an in 2 B shown approximately horizontal loading position. In this loaded position, new product calibres K on the feeder 4th while the rest KR of the previous caliber K still on the gripper 14th as well as between the upper and lower product guides 8th , 9 held, cut open.

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 grippers 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 - d and to control other parameters is the lower and 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.

• - Vorschubgeschwindigkeit der Kaliber K durch die Schneidbrille 5. Vorzugsweise sind die beiden Produktführungen 8, 9 in der ersten Querrichtung 11 separat für jedes Kaliber K vorhanden und separat ansteuerbar.

As both product guides 8th , 9 can be driven in a controlled manner, in particular independently of one another, they determine the - continuous or clocked

• - feed speed of the caliber 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 separately 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 - displaceable to adapt 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 2a shown, or on a packaging element resting on it, such as a cardboard carrier or a flat plastic tray.

Below the feed unit 20th there is also an approximately horizontally running remnant 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 * are driven so that a remaining caliber, for example, falling on it KR can be transported to the rear and onto the lower-lying remnant conveyor 21 falls.

To a leftover piece KR of a product caliber K which cannot be cut open any further and which despite the deactivated gripper, ie in particular opened gripper claws that have been moved out of the remaining piece 16 , but on the gripper, i.e. its main body 14.1 , sticks, reliably peeled off and transported away, show the following 3 - 5 different approaches.

What they all have in common is a pressure ram 25th that is present in the second transverse direction 12th , i.e. on the filing level 4 " as in 1a and 2a is drawn, can be moved back and forth and with its front free end, that is, its contact surface, at least up to the movement path of one on the gripper 14th remaining piece KR can be moved in to the remnant piece KR from the gripper 14th to push away.

The trigger ram 25th is measured in the feed direction 10 behind the rear end of the upper product guide 8th and thus overall behind the product guide 8th , 9 arranged as the upper product guide 8th extends further back than the lower product guide 9 .

In the 3 shows 3a the situation with the leftover piece that can no longer be cut open KR , which is still in the cutting position, i.e. on or in the cutting glasses 5 held by the gripper 14th who have the claw-claws 16 in the leftover piece KR has extended into it and thereby the remaining piece KR still holds.

3b shows - only for the gripper 14th alone - like the leftover piece KR despite being completely withdrawn from it, behind the contact plane between the remnants KR and base body 14.1 located, deactivated gripper claws 16 still on the front surface of the base body 14.1 of the gripper 14th can adhere.

The two scrapers 23 which are inclined to the contact surface of the base body 14.1 of the gripper 14th towards the remnant KR extend, are only on the outside of its back, and are perhaps as shown slightly impressed in its surface, because by these wipers 23 run the gripper claws in the forward pivoted, activated state 16 so that these contaminants adhering to it on the wiper when it is withdrawn 23 get stripped. The scrapers 23 possibly also increase the adhesion of the remaining piece KR on the gripper 14th .

From the in 3a shown end position of the gripper 14th , at the end of the slicing of the product caliber K , this is opposite to the feed direction 10 Move back until the deactivated gripper 14th - as in 3b shown enlarged separately - in the feed direction 10 measured so far behind the rear end of the upper product guide facing away from the glasses 8th that it is still on the open gripper 14th adhering remnants KR in the movement path of the push-off ram, which is still withdrawn upwards 25th is located.

Then according to 3c by driving down in the second transverse direction 12th , i.e. on the filing level 4 " to, the pressure ram 25th against the upward facing surface of the remnant piece KR pushing it away from the front surface of the gripper 14th push away.

This is preferably done when the gripper is at a standstill 14th , however, with appropriately precise control of the motion sequences, it can also be used while the gripper is retracting 14th be performed.

As the feeder 4th in the direction of passage 10 * usually even below the upper product guide 8th extends into it, the detached remnant then falls KR onto the feed conveyor, which is usually already folded down into the horizontal loading position at this point in time 4th , as in 3d shown, so that this must be driven in such a way that its upper run is in the direction of passage 10 * moves and thereby the remnant piece lying on it KR sheds over its front end.

In order to keep a sufficiently large gap between the lower product guide 9 and the front end of the feeder 4th to create, so the leftover piece KR except for the one under the feeder 4th arranged remnant conveyor 21 can fall - which may transport it to the rear and there in a waste container 23 throws off as he does in 2a is shown - must according to 3e usually the lower product guide beforehand 9 around your glasses-side pulley 9a be pivoted around in this viewing direction counterclockwise, so that the lower product guide 9 at least stands vertically or, better, with its strand pointing forwards on the back of the cutting glasses 5 is applied or runs approximately parallel to this.

The gripper 14th can be before reaching the position in which the remaining piece adhering to it KR from the trigger 25th is pushed away, open, but preferably only when between the lower product guide 9 and the front end of the feed belt 4th there is a sufficiently large gap through which this may occur immediately after opening the gripper 14th falling or at the latest the actively detached caliber remnant KR can fall through.

Therefore the lower product guide should 9 be folded up as early as possible, i.e. as soon as the remaining piece KR from the gripper 14th behind the end of the lower product guide 9 is withdrawn, i.e. shortly after leaving the in 3a illustrated end position of the separation.

the 4a, b , 5a, b show procedures in which the remnant KR - after pushing away from the front surface 14.1 by means of the pressure ram 25th as with the 3a until 3c described - on a scrap conveyor 21 falls below the detachment position of the front surface of the base body 14.1 of the gripper 14th is arranged, but above the feed conveyor 4th , at least when it is in the folded-down loading position in these figures.

The scrap conveyor 21 can on the base frame 2 be attached to the machine, in particular between an activated position in which it is under the front surface of the gripper 14th is located, and a deactivated position in which it is not in particular with the feeder folded up into the slicing position 4th collided, be relocatable.

The scrap conveyor 21 can also be attached to the frame of the feeder 4th be attached and with this with pivoting between the slicing position and the loading position of the feeder 4th .

In 4a the remnant conveyor runs 21 in the direction of the figure, and can do this in 4b The remnants of the caliber shown falling on it KR in or against the viewing direction, i.e. at least in the first transverse direction 11 remove from the machine.

In the 5a, b the remnant conveyor extends 21 parallel to the feed conveyor 4th , but above the feed conveyor 4th , and extends with its front end to below the front surface of the base body 14.1 of the gripper located in the release position 14th into it, so that according to 5b Remnants falling on it KR against the direction of flow 10 * can be removed from the rear of the machine.

Preferably, there either remains a sufficient vertical distance between the remnant conveyor 21 and the upper run of the feeder 4th so that a new product caliber K in between can already enter, or the remnant conveyor 21 extends only so far back that in the rear end area of the feeder 4th there is still enough length left so that a new product caliber K can be placed.

In particular, the scrap conveyor is 21 on the support frame of the feeder 4th attached and pivotable with this between its slicing position and its loading position.

In the 5a, b is also a plunger attachment 24 shown, by means of the push-off ram 25th on the upper product guide 8th , so their in the second transverse direction 12th movable day frame, can be attached when the push-off ram 25th only together with the upper product guide 8th in the second transverse direction 12th should be able to move.

Such an attachment is also in the designs of the machine according to 3 and 4th possible.

In the 6a, b is the scrap conveyor 21 , its transport direction in this case, but not necessarily, in and against the horizontal direction of passage 10 * runs so far above that it is still above the upper end of the feeder 4th when it is in the swiveled-up slicing position.

The gripper guide 18th extends against the feed direction 10 so far back over the rear end of the feeder 4th addition to that, the grapple 14th can move backwards until the caliber remnant held on it KR so far above the rear, upper end of the feeder pivoted up into the slicing position 4th is that there is enough space in between in the height to bring in the remnant conveyor 21 is available.

The gripper is in this release position 14th usually in the horizontal direction 10 * behind the rear end of the feeder 4th .

The scrap conveyor 21 is preferably not on the support frame of the feeder 4th attached, but stationary on the base frame of the machine and extends with its front end to the rear end of the feeder 4th or slightly more.

The scrap conveyor 21 leads the according to 6b Remnants falling on it KR , preferably against the direction of flow 10 * , to the back and usually throws them into a waste container 22nd away.
