Definitions

  • the invention relates to a conveyor system for conveying goods, in particular for conveying food products (e.g. stacks or shingles with several slices of cheese, sausage or salami).
  • food products e.g. stacks or shingles with several slices of cheese, sausage or salami.
  • Food processing devices are known from the prior art which cut food products (e.g. pieces of meat, pieces of cheese or sticks of salami) by means of a cutting device into slices which are then placed on a conveyor belt and transported away.
  • food products e.g. pieces of meat, pieces of cheese or sticks of salami
  • discontinuous conveyor instead of a conveyor belt (continuous conveyor) for conveying away the stack of discs, which has several conveyor goods carriers (“mover", “shuttle"), which can accommodate the stack of discs and then in the loaded state be moved along a conveyor path.
  • conveyor goods carriers usually used to convey the stack of discs.
  • acceleration forces or braking forces act on the stack of slices on the conveyed goods carrier, which in extreme cases can lead to the food products slipping off the conveyed goods carrier.
  • the invention is therefore based on the object of creating a correspondingly improved conveyor system.
  • the conveyor system according to the invention is generally suitable for conveying conveyed goods. Preference, however, the conveyor system according to the invention is used for conveying food products, such as stacks or shingles, which consist of several slices of cheese or meat. here it should be noted, however, that a portion can also consist of just a single slice.
  • the conveyor system according to the invention in accordance with the prior art described above, has at least one conveyed goods carrier, which is also referred to as a “mover” or “shuttle” in accordance with the usual technical terminology and is used to hold the food products.
  • a conveyed goods carrier which is also referred to as a “mover” or “shuttle” in accordance with the usual technical terminology and is used to hold the food products.
  • stacks of slices comprising several slices of cheese or sausage can be placed on such a carrier.
  • the conveyor system according to the invention in accordance with the prior art described at the outset, also has a drive system in order to convey the conveyed item carrier discontinuously within a conveying surface along a conveying path.
  • Such conveyor systems consisting of a drive system and at least one conveyed goods carrier can have a fixed conveying path that cannot be changed without a mechanical adaptation, so that the individual conveyed goods carriers are moved more or less on rails.
  • a conveyor system (drive system and conveyed goods carrier) is used in which the conveying path can be freely programmed within a conveying surface, without mechanical adjustments.
  • a conveyor system is marketed by the German company Beckhoff Automation GmbFI under the product name "XPIanar”.
  • the conveyed goods carrier is always aligned parallel to the surface of the conveyor.
  • the consequence of this is that the acceleration forces or braking forces that occur during operation act parallel to the bearing surface of the conveyed goods carrier and, in extreme cases, can cause the food products to slide off the conveyed goods carrier.
  • the conveyor system according to the invention is now distinguished from the prior art in that the drive system can angle the conveyed goods carrier to the conveying surface in order to avoid slipping of the conveyed goods from the receiving surface of the conveyed goods carrier, as will be described in detail below.
  • the conveying surface is aligned essentially horizontally, in particular with an angular deviation from the horizontal of less than 10°, 5° or 2°.
  • the conveying surface is essentially is aligned vertically, in particular with an angular deviation from the vertical of less than 10°, 5° or 2°.
  • the conveying surface is directed obliquely.
  • the conveyor system according to the invention preferably comprises a transfer conveyor, which serves to deposit the food products on the conveyed goods carrier or to remove them from the conveyed goods carrier.
  • a transfer conveyor which serves to deposit the food products on the conveyed goods carrier or to remove them from the conveyed goods carrier.
  • Such transfer conveyors are known per se from the prior art and are described, for example, in German patent application DE 10 2020 105 678.8, so that the content of this earlier patent application of the present description with regard to the structure and functioning of the transfer conveyor is fully applicable is attributable.
  • the transfer conveyor is a continuous conveyor, such as a conveyor belt.
  • the transfer conveyor is preferably arranged above the horizontal conveying surface and can be pivoted vertically.
  • the transfer conveyor is preferably pivoted down onto the conveyed goods carrier located underneath, so that a food product can be conveyed away from the conveyed goods carrier or placed on the conveyed goods carrier.
  • the transfer conveyor is preferably pivoted into a raised passing position, in which the conveyed item carrier can pass the transfer conveyor. This makes sense so that the transfer conveyor does not impede the free mobility of the conveyed item carriers in the conveying surface in the passing position.
  • the transfer conveyor preferably has several parallel narrow conveyor belts, which can also be referred to as knife conveyors or finger conveyors, and can dip into corresponding elongated, parallel depressions in the support surface of the conveyed goods carrier in order to transfer the goods placed on the conveyed goods carrier To reach under and convey food product, as described in the aforementioned German patent application DE 10 2020 105 678.8.
  • the conveyor system according to the invention preferably has a control device which controls the drive system and one of the following states of motion can adjust.
  • control device can control a conveyed goods carrier in such a way that it assumes a loading state in which the conveyed goods carrier is stationary or moves at only a low conveying speed in order to enable the conveyed goods carrier to be loaded with one of the food products.
  • the loading state of the conveyed goods carrier is positioned under the associated transfer conveyor so that the transfer conveyor can store the conveyed goods on the För dergutlini.
  • control device can control a conveyed goods carrier in such a way that it assumes a discharge state in which the conveyed goods carrier also stands still or only moves at a low conveyor speed in order to enable the conveyed goods carrier to be discharged.
  • the conveyed goods carrier In the unloading state, the conveyed goods carrier is positioned under the associated transfer conveyor so that the transfer conveyor can remove the conveyed goods from the conveyed goods carrier.
  • control device can control the conveyed item carrier in such a way that it assumes an acceleration state in which it is accelerated within the conveying surface along the conveying path.
  • control device can also control a conveyed-goods carrier in such a way that it assumes a braking state in which the conveyed-goods carrier is braked along the conveying path.
  • control device preferably controls not only the drive system, but also the transfer conveyor.
  • the control device controls the transfer conveyor in the loading state and in the unloading state in such a way that the transfer conveyor is lowered so that a food product can be deposited or removed from the conveyed goods carrier. Otherwise, the control device controls the transfer conveyor in such a way that it is raised into a passing position in order not to impede the free mobility of the conveyed item carriers within the conveying surface.
  • the angle adjustment of the loading and unloading conveyor can optionally also be adjusted manually
  • the control device also controls the conveyed item carrier in such a way that it is angled relative to the conveying surface in order to facilitate product placement or product removal from the conveyed item carrier.
  • the goods carrier is preferably tilted forward in the conveying direction.
  • the conveyed-goods carrier is preferably tilted backwards, counter to the conveying direction.
  • the angling of the conveyed-goods carrier relative to the conveying surface is intended to prevent the food products from slipping off the conveyed-goods carrier due to the inertial forces acting during operation.
  • the conveyed-goods carrier In the accelerated state, the conveyed-goods carrier is therefore preferably tilted forward in the direction of movement of the conveyed-goods carrier.
  • the conveyed-goods carrier In the braking state, on the other hand, the conveyed-goods carrier is preferably tilted backwards, counter to the direction of movement of the conveyed-goods carrier. In this way, the food products can be prevented from sliding down from the conveyed goods carrier, largely independently of the braking forces or acceleration forces that occur.
  • the tilting angle of the conveyed goods carrier is adapted to the inertial forces that occur in such a way that the resultant of the inertial force on the one hand and the gravitational force on the other hand is always aligned at right angles to the bearing surface of the conveyed goods carrier.
  • the magnetic levitation system can be used as the drive system, which is available under the product name "XPIanar" from the German company Beckhoff Automation GmbFI. It should also be mentioned that the drive system preferably works without physical contact between It should also be mentioned that the drive system is preferably a magnetic levitation system, so that the carrier levitates at a distance above the conveying surface.
  • the drive system preferably has a plurality of modules which adjoin one another and together form the conveying surface.
  • the modules of the drive system are therefore preferably each rectangular, so that the modules can be put together to form the conveying surface without any gaps. Alternatively, however, there is also the possibility that there is a small distance between the individual modules of the drive system.
  • the conveying path is preferably freely programmable within the conveying surface and Although without mechanical adjustments, so that the conveyed goods carrier is not tied to a fixed, predetermined conveying path.
  • the conveyed goods carrier can have several parallel and elongated depressions on its upper side, into which - as already briefly mentioned above - the individual knife conveyors or finger conveyor belts of the transfer conveyor can dip in order to To reach under conveyed goods carrier lying food product and promote ab.
  • the depressions in the conveyed goods carrier are preferably wider than the individual conveyor belts (finger conveyors or knife conveyor belts) of the transfer conveyor, so that the individual conveyor belts of the transfer conveyor can dip into the elongated depressions in the conveyed goods carrier.
  • the gap between the immediately adjacent conveyor belts of the trans fer considereders is therefore preferably larger than the distance between the immediately neigh th depressions in the conveyed goods carrier.
  • the conveyed goods carrier can have a large number of pins on its upper side, which are arranged in a matrix in pin rows and pin columns, with the immediately adjacent pin rows and also the immediately adjacent pin columns each enclosing one of the depressions already mentioned above, into which the finger conveyors or knife conveyor of the transfer conveyor.
