Definitions

  • the invention relates to a device for slicing food products, in particular high-performance slicers, with a product feed that comprises at least one conveyor device with which at least one product can be fed to a cutting plane in which at least one cutting knife, in particular rotating and / or rotating, moves ,
  • the cutting knife can be, for example, a sickle knife, an orbital knife or a circular knife.
  • a food product with a defined speed profile is conveyed to a rotating knife.
  • the knife cuts slices from the food product.
  • the slice thickness is defined by the feed speed of the food product relative to the speed of the cutting knife, which can be several hundred to several thousand revolutions per minute.
  • Traction systems i.e. the product is conveyed by one or more driven rollers or belts.
  • a product can ideally be transported without slippage.
  • two parallel conveyor belts, in particular below and above the product, between which the product is guided can be provided for each product.
  • an upper hold-down system can be provided, which presses the product onto the lower conveyor belt.
  • the hold-down system in particular has the task of stabilizing the product when the cutting knife enters and exits.
  • a plurality of food products, in particular arranged next to one another, can also be fed to a cutting plane at the same time. There the food products can be cut open by a common cutting knife or by several individual cutting knives.
  • the product feed can, for example, be controlled individually for each track.
  • each track can be equipped with its own conveyor, in particular an endless belt conveyor and / or a product holder.
  • a common conveying device can be provided for all tracks in a more cost-effective embodiment.
  • Several products arranged next to each other are fed to the cutting plane using a common product feed.
  • all product holders are only moved together, i.e. all product holders engaging at the rear end of the product are always in the same position with regard to the conveying direction.
  • the products are moved in all tracks together using the endless belt conveyor and / or the product holder.
  • the product feed and thus also the product holder are in practice mostly inclined, in particular at a feed angle of 30 ° to 80 ° with respect to the horizontal.
  • a slide can be provided which prevents the end piece from reaching the cutting plane.
  • a hold-down device for the food product and, on the other hand, a slide that prevent a product end piece from reaching the cutting plane are therefore necessary for an optimal cutting result.
  • Such a slide can also act as a stop when a new product is inserted into the slicing device manually or automatically.
  • the slide prevents movement of the product to the cutting plane if the product holder engages the rear end of the product while preparing for the cutting process.
  • a slide is particularly advantageous when several food products are to be cut open, since the slide can then serve as a stop for all products at the same time. If, however, what happens regularly in practice, the products are of different lengths and are acted upon at their rear ends by a product feed that can only be moved as a whole, ie cannot be operated individually, then between the slide and individual product holders Product feeder products of different lengths jammed. A longer food product is compressed more than a shorter food product. This can be undesirable Deformation or even damage to the products that must be avoided.
  • Such product impairments can occur not only on multi-track, but also on such slicers that only cut one product at a time, if, for example, due to the product consistency when preparing the cutting process, a product holder has to apply a relatively high force to the rear end of the product in order to achieve a sufficient level to ensure a firm hold.
  • the product holders are usually pulled back after they have come into engagement with the products before the slide is opened. This movement of the product feed in the opposite direction slows down the cutting process and thus reduces the overall product throughput that can be achieved.
  • a hold-down device that presses the product against a lower product support
  • a pressing device can be provided that presses the product against a lateral product system.
  • a slicing device In order to avoid the above-mentioned problems, a slicing device must consequently be able to perform a plurality of functions that are partially independent of one another and partially interrelated, so that an optimal cutting result and the highest possible cutting performance can be achieved. Such requirements are placed both on devices with which only one product can be cut at a time and on devices which are capable of multi-track operation. Also, at least with regard to some requirements, it does not matter how the product feeder attacks the product.
  • the product feed can For example, have one or more product holders which are designed, for example, as product grippers provided with claws or as pure sliders. In addition, it is common, but not essential, for the product feed to engage at the rear end of the product. The product feed can, for example, also attack the rear area of the product from the side or from the side.
  • the slicing device further comprises at least one work unit for at least temporarily handling the product, which is effective in a locked position as a stop for the front end of the product, the work unit located in the locked position being resilient to a force applied in the conveying direction.
  • the work unit is thus in particular not rigid. This can be done, for example, by means of an elastic and / or flexible material, e.g. a rubber or plastic material can be realized. Alternatively or additionally, spring systems or pneumatic and / or hydraulic systems are conceivable, for example.
  • the work unit can yield evenly or can be gradually adjusted to different positions, particularly depending on the applied force.
  • the compliance behavior can in particular be adjustable, e.g. through the choice of material, the choice of the spring used or an adjustment or control or regulation of the pneumatic and / or hydraulic system. This makes it possible to regulate whether or to what extent the work unit yields depending on an acting force.
  • the work unit located in the locked position can be moved in the conveying direction by a force that exceeds a threshold value and is applied in the conveying direction with a component, in particular against the action of a holding force.
  • the path for the product is at least partially cleared in the conveying direction.
  • spring systems or pneumatic and / or hydraulic systems are conceivable.
  • the work unit can move evenly or in stages - in particular depending on the applied force - can be adjusted to different positions.
  • the threshold value and / or the holding force are particularly adjustable. This can e.g. the resistance to be determined, which is opposed to a product. If the pressure is sufficiently high, the blocking position is at least partially or temporarily released and the work unit at least partially clears the way for the product.
  • the product feed is designed to be multi-lane in order to cut open several products at the same time.
  • the work unit can be operated individually for each track.
  • the working unit for each track comprises an adjustable holding section, which in a blocking position performs a blocking function for the product, the holding sections being operable independently of one another.
  • the holding sections being operable independently of one another.
  • the threshold value and / or the holding force can be set individually for each track.
  • These values are preferably chosen to be approximately the same.
  • the holding section gives way sooner or later and thus at least partially or a little way for the product in the direction of the cutting plane.
  • the work unit is designed to be multifunctional, the work unit being adjustable into a pressing position, in which the work unit presses the product that is movable in the conveying direction against a lower product support and / or a lateral product support, and into the locked position, in which the work unit counteracts movement of the product in the conveying direction.
  • the work unit When pressed, the work unit can act as a hold-down for the product.
  • the product can be clamped between the lower product support, in particular a conveyor belt, a roller conveyor or an immovable surface with a low coefficient of static friction, and the work unit.
  • the product in the pressing position, can also be pressed against a lateral product system, for example a side wall, in particular a conveyor belt, a roller conveyor or an immovable surface with a low coefficient of static friction.
  • a lateral product system for example a side wall, in particular a conveyor belt, a roller conveyor or an immovable surface with a low coefficient of static friction.
  • the product is thereby stabilized, in particular when the cutting knife enters and exits.
  • the products can be cut into even slices.
  • the work unit counteracts movement of the product in the conveying direction, i.e. in particular, the path to the cutting knife is blocked for the product.
  • the work unit thus fulfills a double function and can thus take over those functions which, in known slicers, are performed by two structurally separate and separately operated devices, namely a product hold-down device on the one hand and a slide valve on the other hand.
  • This double function means that only one device is required, which can save costs.
  • the construction of the slicer is also particularly simple. This also reduces maintenance work.
  • the work unit can be passive or active.
  • a passive work unit can comprise, for example, a bent sheet metal part or a non-driven roller conveyor.
  • an active work unit for example, a belt belt or driven rollers can be provided.
  • the conveying of the product along and / or against the conveying direction can be supported in the pressing position of the work unit.
  • the elimination of an end piece, for example, can also be actively supported in the locked position.
  • the pressing position can also be a traction or conveying position, since the work unit at least supports the conveying of the product.
  • the work unit located in the locked position is effective, depending on the operating situation, as a stop for the front end of the product or as a deflector for a product end piece to be removed.
  • the stop can prevent the product holder from engaging safely, e.g. guaranteed in the rear end of the product.
  • the product is not yet pushed along the conveying direction to the cutting plane due to the stop.
  • the working unit in the locked position can also act as a deflector for a product end piece to be removed.
  • the locking position prevents the product end piece from falling into the cutting plane when it is disengaged from the product holder. Otherwise, this could lead, for example, to undesired chips and contamination of the slicing device.
  • the end piece When rejecting, i.e. Removing the end piece from the product feed, the end piece can, for example, be transported down into a shaft or laterally out of the conveying path.
  • the working unit can have a surface that runs vertically or obliquely to the product support in order to discharge the product end piece. In this way, a targeted slipping or sliding or disposal of the end piece is ensured.
  • the work unit can act passively as a deflector. It is also conceivable to actively design the work unit, for example by means of a driven belt, which actively supports the removal of the end piece. This enables a particularly reliable and quick release of the product feed.
  • the movement of the work unit is at least part of an adjustment movement of the work unit into the pressing position.
  • the work unit is thus at least partially adjusted to the pressing position by the applied force.
  • the movement due to the threshold being exceeded thus forms in particular the beginning of the movement for adjusting the work unit from the locked position to the pressing position. This saves valuable time.
  • the working unit can be adjusted directly from the blocking position into the pressing position and vice versa.
  • no intermediate positions are provided.
  • the working unit can be adjusted starting from the blocking position without a movement component directed against the conveying direction.
  • the work unit can be pivoted with a component in the conveying direction into a position that clears the way for the product. In this way, the product does not first have to be moved against the product feed direction, for example with the aid of the product holder, so that the work unit can be adjusted.
  • Such an adjustment of the work unit for example in the conveying direction or perpendicularly from the conveying direction or a lateral movement out of the conveying path, is particularly advantageous.
  • the working speed of the slicing device can be increased in this way since the product conveyance does not have to be interrupted and it is also not necessary to release the product before the conveying path is released withdraw by means of a product holder, ie to move against the conveying direction.
  • an adjustment movement of the work unit comprises a swivel movement.
  • the working unit can in particular comprise at least one joint or hinge.
  • the working unit comprises at least one adjustable holding section, which in the pressing position performs a pressing function and in the blocking position a blocking function for the product.
  • the holding section can be used as a passive element, e.g. as a bent sheet metal part or as a non-driven roller conveyor, or as an active conveyor element, e.g. be designed as a belt belt or driven roller conveyor.
  • the holding section has in particular an at least substantially flat holding surface facing the product, which preferably runs at least approximately parallel to the conveying direction in the pressing position and at least approximately perpendicular to the conveying direction in the blocking position. In this way, the largest possible contact area with the product can be made available both in the pressing position and in the blocking position.
  • the holding section can also have a different geometric shape.
  • the holding surface can press the product from above onto a lower product support or from the side against a product system.
  • the position of the work unit in particular the distance of the work unit from the lower product support and / or from the lateral product installation, can be changed.
  • the work unit can be adjusted to the diameter of the product, for example.
  • the position can be changed manually, for example by means of adjusting screws, or automatically, for example by means of an electrical, electromagnetic, hydraulic and / or pneumatic drive.
  • an adjustment movement of the work unit and a movement for changing the position of the work unit are independent of one another.
  • the height of the work unit and / or the lateral position of the work unit can be changed independently of the adjustment movement between the pressing position and the blocking position.
  • a separate drive is provided for each of these two movements.
  • the work unit is thus particularly variable and can be adapted with high precision to the respective circumstances, in particular to the product to be cut. Thanks to the independent drives, the product can be handled safely and in a controlled manner, which in particular leads to an exact guidance of the product and a good cutting result.
  • an adjustment movement of the work unit and a movement for changing the position of the work unit are positively coupled to one another.
  • a link guide can be provided.
  • the adjusting movement can in particular comprise a curved section in order to additionally transfer the working unit from the pressing position into the blocking position and vice versa when the position of the working unit changes.
  • various movements are carried out based on a single excitation movement.
  • Such an excitation movement can be implemented, for example, with only a single drive, which can save costs.
  • the working unit comprises a base and on the base a holding section for the product, the position of the base being changeable and the holding section being adjustable.
  • the holding section is in particular articulated to the base and can in this way by a pressing position can be adjusted into a blocking position, for example by pivoting.

  • the height and / or the lateral distance of the base relative to the product can thus be carried out independently of the adjustment movement of the holding section from the pressing position and the blocking position or vice versa. This ensures a particularly precise adaptation of the work unit to the product.
  • a movement for changing the position of the base and an adjusting movement of the holding section can be derived from a single movement of the work unit, in particular the movement of the work unit being effected by means of a single drive. This is done, for example, with the aid of a backdrop guide.

  • Each holding element 20 is assigned its own pivoting drive 26, which comprises a piston / cylinder arrangement which is articulated at one end to the base 18 and at the other end to the respective holding element 20, the holding elements 20 each being articulated with the base 18 are connected, specifically on a pivot axis spaced from the engagement axis of the piston / cylinder arrangement, so that a change in length of the piston / cylinder arrangement generates a pivoting movement of the holding element 20 in question.
  • a locking position of the holding elements 20 is in Fig. 2 shown.
  • the holding elements 20 are oriented perpendicular to the front conveyor 11 and form a lock for the product end pieces 30.
  • the holding elements 20 serve as hold-downs for the products 12.
  • the products 12 are held by the gripper 28 and conveyed to the sickle knife 14 by means of the endless conveyor belt 10, the front conveyor 11 and the belt belts 22 until the products 12 are almost completely cut open. If only the product end pieces 30 are left (see Fig. 2 ), these are pulled back against the conveying direction F by means of the grippers 28.
  • the height adjustment drive 24 moves the base 18 upwards along the height adjustment direction H, while the pivoting drive 26 pivots the holding elements 20 out of the pressing position into the blocking position.
  • the holding elements 20 thus form a lock for the product end pieces 30.
  • These end pieces 30 can therefore be used despite the inclined position of the product support do not fall into the cutting plane S when the grippers 28 are disengaged from the end pieces 30 to release the end pieces 30.
  • the holding elements 20 consequently serve as deflectors for the end pieces 30, which ensures that the end pieces 30 do not come forward, but rather through an opening in the support plane that is temporarily released for this purpose fall below, for example in a shaft, not shown.
  • the band straps 22 of the holding elements 20 which are active during the cutting operation can remain activated or be reactivated.
  • Fig. 2 shows, with this slicer the product feed remains inclined, with a loading device comprising the conveyor 10 from an essentially horizontal loading position according to FIG Fig. 2 , in which the products 12 to be cut are brought into the inclined cutting position according to Fig. 1 is pivoted.
  • this configuration is not mandatory and can be modified within the scope of the invention.
  • Fig. 3 10 is a perspective view of the slicer of FIG Fig. 1 shown with four newly loaded products 12, which are fed to the cutting knife 14 by the common endless conveyor belt 10 and the front conveyor 11.
  • the grippers 28 attached to a common carrier 32 cannot be moved individually by the track, but only together along or against the conveying direction F by the driven carrier 32.
  • Each track is assigned its own holding element 20, which in each case comprises a separate pivot drive 26.
  • the height adjustment is common Height adjustment drive 24 is provided, which can move the base 18 together with the holding elements 20 along the height adjustment direction H.
  • the holding elements 20 are designed to be flexible independently of one another, so that they can yield to the products 12 from a certain force, i.e. a product 12 pressed by means of the product holder 28 against the holding element 20 assigned to it, the path in the conveying direction F will be cleared as soon as the force exceeds a predetermined level.
  • the products 12 can be relieved individually if this is necessary due to a different length of the products 12, as will be explained in more detail below.
  • FIG. 4 and 5 This situation is in Fig. 4 and 5 shown.
  • the holding elements 20, which are assigned to longer products 12, are deflected in the conveying direction F and are thus already pivoted a little way from the original blocking position in the direction of the pressing position, but without completely clearing the way for the products 12, so that a holding force is still effective , with which the deflected holding elements 20 continue to oppose the products 12 in question in order to ensure that the product holders 28 engage as intended.
  • the individual resilience of the holding elements 20 is realized by the pneumatic devices of the pivoting drives 26 which act in the manner of a spring and are independent of one another.
  • the resilience behavior of the holding elements 20 can be adjusted on the pneumatic swivel drives 26 or in another way. The adjustment is made in such a way that the products 12 are opposed to a sufficiently large force on the one hand so that the grippers 28 can engage in the rear end 30 of the product, while on the other hand the holding elements 20 give way before the products 12 are compressed too much.
  • the holding elements 20 can be pivoted further from the locked position into the pressing position by means of the pivoting drives 26 ( Fig. 6 ).
  • the holding elements 20 are in constant contact with the products 12.
  • the base 18 is moved downwards by means of the height adjustment drive 24.
  • the products 12 are conveyed in the conveying direction F to the cutting plane S with the aid of the endless conveyor belt 10, the front conveyor 11 and the gripper 28.
  • While the holding elements 20 can yield independently or are deflected independently of one another and thus as a function of the respective product 12 or of the force applied via the product 12, the subsequent adjustment to the pressing position takes place to initiate the cutting operation (and later also the resetting from the pressing position into the blocking position) for all holding elements 20 together. Consequently, only a single common active drive is required for the individual pivot drives 26 of the holding elements 20. According to the invention, however, it is not excluded that everyone Swivel drive 26 can be controlled separately and operated independently of the other swivel drives 26, so that the holding elements 20 not only yield individually, but can also be individually adjusted as desired.
  • blocking elements become hold-down devices, so to speak, each time by a simple swiveling movement.
  • the holding elements 20 are in the pressing position, the products 12 are conveyed further along the conveying direction F until they reach the cutting plane and the slicing operation begins (cf. Fig. 1 ).
  • the work unit 16 is thus multifunctional and serves as a product stop during the preparation of the slicing operation, as a product hold-down device during the slicing and as an end piece deflector at the end of the slicing process, and in addition, in the case of an active configuration, the work unit 16 also fulfills a conveying function with the hold-down function in order to achieve this or to transport each product 12 to the cutting plane S, together with the active front conveyor 11, which can alternatively also be passive and can only serve as a product support.
