Semi-automatic weighing system

Equipment designed for semi-automatic weighing of fish batches that are being conveyed continuously.

This is a weighing system suitable for packaging operations in boxes, bags or trays.

The weighing system consists of two scales that weigh batches alternately and discontinuously.

It functions as follows:

  • Scale number 1 of the equipment automatically weighs a batch, whose weight is preset within a predetermined range.
  • After the automatic weighing of the batch, the operator can manually adjust the weight of the batch more accurately (if necessary), and then remove the container with the batch of fish, leaving scale no. 1 free to weigh the next batch
  • Scale number 2 of the equipment automatically weighs another batch, whose weight is also preset within a predetermined range.
  • After this, the operator can manually adjust the weight of the batch on scale Nº 2, and then remove the container with the batch of fish, leaving the scale free to weigh the next batch.

Product conveyor to the weighing system

  • Main loading conveyor of the weighing system with pneumatic arms and unloading mouths at its end.
  • Plastic modular belt conveyor by the Intralox brand (FDA and USDA approved).
  • Belt sliding profiles in plastic approved for use in contact with food.
  • Driven by an electric motor reducer with hollow axle with no mechanical transmissions, directly coupled to the traction axle with its corresponding reaction arm and protective  flexible coupling.
  • Variable conveyor speed by means of a frequency variator.
  • Fairing on the rotating elements with a protective casing, built-in AISI-316 quality stainless steel.
  • Squared section stainless steel shafts, with fretworked sprockets on them and mounted on polyamide bearings with ball bearings and seals.
  • Pneumatically driven product diverters, to direct the product to the weighing systems.
  • Flanged and screwed legs on resistant and stable supports, with spherical feet adjustable in height for correct levelling.
  • Open structure, built with plate and profiles in stainless steel quality AISI-316.
