Definitions

  • the invention relates to a device for weight-controlled assembly of products into a lot, comprising a feed element for feeding a plurality of unsorted products, a device for separating the products, a discharge element for discharging the separated products and a weighing device. Further, the invention is concerned with a method for weight controlled assembly of products into a lot, comprising the steps of: feeding a plurality of unsorted products, separating the products, weighing the individual products, and assembling a lot.

  • packaging lots must meet different requirements. These requirements include, in particular, the achievement of a target or
  • the total weight of the packaging content should be, for example, 300g.
  • the fillets that come out of processing each weigh about 50 g, so that for a packaging between, amaschineslos usually six of these fish fillets must be put together.
  • the weights of fish fillets vary. Some weigh more, some less than 50g. Simply putting together each lot of packaging by number of units would therefore possibly lead either to a failure to meet the minimum weight or to overfilling the packaging.
  • the fish fillets are weighed and from a pool of several fish fillets the six fish fillets are selected which on the one hand reach the minimum weight and on the other hand an overfill above minimize the minimum weight.
  • the products are separated from a disordered or unsorted mixture.
  • the separation can be done manually or by means of suitable handling devices.
  • the supplied on a feeding element products are removed by means of a gripper or by means of suction nozzles from the feed and stored at another position on a discharge conveyor, on the discharge conveyor the products are then separated from a previously disordered / unsorted product stream.
  • the products are then weighed prior to assembly into a packaging lot.
  • the products are fed to a balance. After weighing the individual products, they are put together to form the packaging lot with a defined weight. Feeding to the scale and assembling the lot can be done manually.
  • the separated products can also be sequentially automatically fed to a balance and directly to a packaging lot.
  • this known device or the corresponding method has the disadvantage that ultimately only the last still to be awarded position of a lot to optimize the total weight is available, since the other positions of a lot are already determined by already selected and associated products. Furthermore, it may be that a fish fillet, which is not assigned to any of the lots to be filled, a multiple Circulation takes place, which limits the performance of the device and thus reduces the efficiency.

  • short transport routes are realized, which transport the Protect the product and minimize transport errors.
  • Due to the mobility of the holding element search movements are possible on the feeding.
  • the holding element scans the area of the feed element immediately in front of the associated container, thereby ensuring a reliable pick-up of the product independent of the position of the product on the feed element.
  • all holding elements, containers, elements for weighing the products and buffer are separately controllable. This makes it possible to put together an optimal lot from a large number of different products before it is fed to a packaging or a further production step.
  • the object is achieved by a method with the above-mentioned steps in that the separation of the products and the feeding of the separated products to a weighing device takes place automatically, several individual products being buffered separately and in knowledge of the individual weights programmatically to a lot be assembled with an optimal weight combination.
  • the parallel caching of several products of known weight, the assembly of lots is improved because all positions of a lot to the final occupancy are freely selectable, so that an optimal weight combination can be achieved. Automation leads to a reduction in manual effort, which in turn leads to cost savings.
