Definitions

  • the invention relates to a device for slicing food products, in particular high-performance slicers, with a product feed comprising at least one conveying device, with which at least one product can be fed to a cutting plane, in which at least one cutting blade, in particular rotating and / or circulating, moving.
  • the cutting knife may be, for example, a sickle knife, an orbital knife or a circular knife.
  • a food product having a defined velocity profile is conveyed to a rotating knife.
  • the knife cuts slices off the food product.
  • the slice thickness is defined by the feed rate 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 are used, for example, ie the product is conveyed by one or more driven rollers or belts.
  • a product can thus ideally be transported without slippage.
  • two parallel conveyor belts in particular below and above the product, can be provided for each product, between which the product is guided.
  • an upper hold-down system can be provided which presses the product onto the lower conveyor belt.
  • the hold-down system has the particular task of stabilizing the product when entering and leaving the cutting blade.
  • the product supply can be controlled, for example track individual.
  • a common conveyor for all tracks can be provided.
  • Several juxtaposed products are fed to the cutting plane by means of a common product feed.
  • all product holders are only moved together, ie all product holders engaging each at the rear end of the product are always in the same position with respect to the conveying direction.
  • the products are moved in all tracks together using the endless belt conveyor and / or the product holder.
  • the end of the food product located on the product holder must be eliminated.
  • the product feed and thus also the product holder is usually tilted in practice, in particular at a feed angle of 30 ° to 80 ° relative to the horizontal.
  • a slider may be provided, which prevents the tail from reaching the cutting plane.
  • a hold-down device for the food product and, on the other hand, a slide which, on the one hand, prevents a product end piece from entering the cutting plane are therefore necessary on the one hand for an optimum cutting result.
  • Such a slide can also act as a stop when a new product is inserted manually or automatically into the slicing device.
  • the slider prevents movement of the product to the cutting plane when the product holder engages the rear end of the product during the preparation of the cutting operation.
  • a slider is particularly advantageous if several food products to be cut, because then the slide can serve as a stop for all products at the same time. If, however, what happens regularly in practice, the products have a different length and be acted upon at their rear ends by a product feeder, which moves only as a whole, ie can not be operated track individual, then products of different lengths are clamped between the slide and eg individual product holders of the product feeder. A longer food product is more compressed than a shorter food product. This can lead to undesirable deformations or even inevitable damage to the products.
  • Such product impairments can occur not only on multi-lane but also on slitters that cut only one product at a time, for example, because of product consistency in the preparation of the cutting operation, a product holder must apply a relatively high force to the rear end of the product to provide sufficient to ensure firm hold.
  • the product holders In order for the products to relax before the actual cutting process begins, the product holders, once engaged with the products, are usually withdrawn before the pusher is opened. This movement of the product feed counter to the conveying direction slows down the cutting process and thus reduces overall the achievable product throughput.
  • a hold-down which presses the product against a lower product support
  • a pressing device which presses the product against a lateral product system
  • a slicing apparatus must have a plurality of partially independent ones and partially perform interrelated functions, so that an optimal cutting result and the highest possible cutting performance can be achieved.
  • Such requirements are placed on both devices that can only cut a product at a time, as well as on devices that are capable of a multi-lane operation.
  • the product supply may, for example, have one or more product holders which are designed, for example, as product claws provided with claws or as pure slides.
  • the product feeder to engage the rear end of the product.
  • the product feeder can also attack, for example, laterally or from the side at the rear of the product.
  • the slicing device comprises at least one multifunctional working unit for at least temporary handling of the product, the working unit being adjustable into a pressing position in which the working unit presses the product movable in the conveying direction against a lower product support and / or a lateral product contact, and into a blocking position is, wherein the working unit, starting from the blocking position with a component in the conveying direction in a path for the product releasing position is pivotable.
  • the working unit can act as a hold-down for the product in the pressing position.
  • 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 static friction coefficient, and the working unit.
  • the product in the pressing position, can also be pressed against a lateral product installation, for example a side wall, in particular a conveyor belt, a roller conveyor or an immovable surface with a low static friction coefficient.
  • a lateral product installation for example a side wall, in particular a conveyor belt, a roller conveyor or an immovable surface with a low static friction coefficient.
  • the product is thereby stabilized, in particular during the entry and exit of the cutting blade.
  • the product is thereby stabilized, in particular during the entry and exit of the cutting blade.
  • e.g. allows slicing the products into even slices.
  • the working unit counteracts a movement of the product in the conveying direction, ie in particular the path to the cutting blade is blocked for the product.
  • the working unit according to the invention thus fulfills a dual function and can thus assume those functions which are fulfilled in known slicers by two structurally separate and separately operated devices, namely a product holder on the one hand and a slider on the other hand.
  • the work unit may be passive or active.
  • a passive unit of work may e.g. a sheet metal bending part or a non-driven roller conveyor include.
  • an active working unit for example, a belt or driven rollers may be provided.
  • the conveying of the product along and / or against the conveying direction in the pressing position of the working unit can be supported.
  • the blocking position e.g. the termination of an end piece is actively supported.
  • the pressing position can simultaneously be a traction or conveying position, since the working unit at least supports the conveying of the product.
  • the working unit located in the blocking position is effective as a stop for the front end of the product or as a deflector for a product end to be rejected, depending on the operating situation.
  • the working unit in the blocking position can also be effective as a deflector for a product end to be rejected.
  • the locking position prevents the product end from falling into the cutting plane when it is disengaged from the product holder. Otherwise, this could, for example, lead to unwanted chips and impurities of the slicing device.
  • the tail When rejecting, i. Removing the end piece from the product feeder, the tail can be transported, for example, down into a shaft or laterally out of the conveyor.
  • the working unit can have a surface running vertically or obliquely to the product support in order to discharge the product end piece. In this way, a targeted slipping or slipping or disposal of the tail is ensured.
  • the work unit can passively act as a deflector. It is also conceivable to actively form the working unit, for example by means of a driven belt belt, whereby the separation of the tail is actively supported. This allows a particularly reliable and fast release of the product feeder.
  • the working unit located in the blocking position is made yielding with respect to a force applied in the conveying direction.
  • the working unit is thus not rigid in particular. This can be achieved, for example, by an elastic and / or flexible material, e.g. a rubber or plastic material can be realized. Alternatively or additionally, for example, spring systems or pneumatic and / or hydraulic systems are conceivable.
  • the working unit can yield evenly or in stages - especially in dependence on the applied force - be adjusted in different positions.
  • the compliance behavior may in particular be adjustable, e.g. by 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 can be used to regulate whether or how much the working unit gives way depending on an acting force.
  • the working unit located in the blocking position is movable by a force exceeding a threshold, applied in the conveying direction with a component in the conveying direction, in particular against the action of a holding force. From a certain force thus the way for the product is released at least a little way in the conveying direction.
  • a force exceeding a threshold For example, spring systems or pneumatic and / or hydraulic systems are conceivable.
  • the work unit can be moved evenly or gradually - in particular depending on the applied force - be adjusted in different positions.
  • the threshold value and / or the holding force are in particular adjustable. Thereby, 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 working unit at least partially clears the way for the product.
  • the movement of the working unit is at least a part of an adjusting movement of the working unit into the pressing position.
  • the applied force thus at least partially displaces the working unit into the pressing position.
  • the movement due to the threshold crossing thus forms in particular already the beginning of the movement for adjusting the working unit from the blocking position to the pressing position. This saves valuable time.
  • the working unit is adjustable from the blocking position directly into the pressing position and vice versa. There are thus, for example, no intermediate positions provided. Alternatively, however, it is also conceivable to first transfer the working unit from the blocking position into an intermediate position. In this intermediate position, for example, another function could be performed. Only after this intermediate position, the working unit would be adjusted in the Andrückwolf. In both cases, the working unit may be permanently in contact with the product during the adjustment movement.
  • the working unit is adjustable without a movement component directed counter to the conveying direction and can be pivoted with a component in the conveying direction into a position releasing the path for the product.
  • the product does not have to be moved in this way first, for example, by means of the product holder in the opposite direction of the product feed, so that the working unit can be adjusted.
  • Such adjustment of the working unit e.g. in the conveying direction or perpendicular from the conveying direction or a lateral movement out of the conveying path is particularly advantageous.
  • the speed of operation of the slicing apparatus can be increased in this way, since the product delivery need not be interrupted and it is not necessary to retract the product by means of a product holder before releasing the conveying path, i. to move against the conveying direction.
  • an adjusting movement of the working unit comprises a pivoting movement.
  • the working unit may comprise at least one joint or hinge.
  • the working unit comprises at least one adjustable holding section, which exerts a pressing function in the pressing position and a blocking function for the product in the blocking position.
  • the holding section can be used as a passive element, e.g. as a sheet metal bent part or as a non-driven roller conveyor, or as an active conveying element, e.g. be designed as a belt or driven roller conveyor.
  • the holding section has, in particular, an at least substantially planar holding surface facing the product, which preferably extends 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 surface with the product can be made available both in the pressing position and in the blocking position.
  • the holding portion may 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 installation.
  • the position of the working unit in particular the distance of the working unit from the lower product support and / or from the lateral product installation, can be changed.
  • the working unit can be set, for example, to the diameter of the product.
  • the position change can be done manually, for example by means of screws, or automatically, for example by means of an electric, electromagnetic, hydraulic and / or pneumatic drive.
  • an adjusting movement of the working unit and a movement for changing the position of the working unit independent from each other.
  • the height of the working unit and / or the lateral position of the working unit can be changed independently of the adjusting movement between the pressing position and the blocking position.
  • a separate drive is provided for each of these two movements.
  • the working unit is thus particularly variable and with high precision to the particular circumstances, in particular to be sliced product customizable. Thanks to the independent drives, the product can be handled safely and in a controlled manner, which in particular leads to exact guidance of the product and a good cutting result.
  • an adjusting movement of the working unit and a movement for changing the position of the working unit are positively coupled with each other.
  • a slotted guide can be provided.
  • the adjusting movement may 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. In this way, various movements are performed due to a single exciter movement. Such excitation movement can be realized for example with only a single drive, which costs can be saved.
  • the working unit comprises a base and at the base a holding portion for the product, wherein the position of the base is variable and the holding portion is adjustable.
  • the holding portion is in particular hingedly connected to the base and can be adjusted in this way from a pressing position into a blocking position, for example by pivoting.
  • the height and / or the lateral distance of the base can be adjusted relative to the product.
  • the holding section is movable relative to the base.
  • the holding portion e.g. be pivoted relative to the base by means of a joint.
  • a movement of the base for changing the position and an adjusting movement of the holding portion are independent of each other and in particular effected by means of separate drives.
  • the height and / or the lateral distance of the base relative to the product can thus be carried out independently of the adjusting movement of the holding section from the pressing position and the blocking position or vice versa. This ensures a particularly precise adjustment of the working unit to the product.
  • a movement for changing the position of the base and an adjusting movement of the holding portion are derivable from a single movement of the working unit, in particular, the movement of the working unit is effected by means of a single drive.
  • a single drive for example, a slotted guide.
  • the adjusting movement may comprise a curved section. In this way, for example, a single drive for both adjustment movements may be sufficient. This leads to a significant cost reduction.

In this way, all tracks can be blocked independently of each other, for example. Also, the compliance or threshold of the unit of work can be customized for each track and product.
  • the holding portions are attached to a common base of the working unit and independently adjustable relative to the base. This allows flexible adaptation. On the common basis all holding sections and thus all tracks are centrally influenced.
  • the position of the base in particular its distance from the lower product support and / or from the lateral product installation, can be changed.
