Definitions

  • the invention relates to a device for turning fish fillets, comprising a feeding element for feeding the fish fillets in the area of a turning station, the turning station itself and a discharge for discharging the turned fish fillets, wherein the turning station for turning the fish fillets about the longitudinal axis and one perpendicular to the longitudinal axis extending axis is formed and set up.
  • Such devices are used in the food industry and especially in the fish processing industry.
  • the devices turn the products around one or two axes in order to optimally position and align the products for the subsequent processing steps.
  • the reasons for the turn can be manifold.
  • products can be rotated correspondingly about their longitudinal axis in order to remove unwanted product areas which point in the direction away from the feed belt before turning, in the subsequent step from below, ie from the feed element facing side, or vice versa.
  • the desired direction of travel that is, the side with which the product is leading, may vary for reasons of product geometry, accessibility to machining tools, or other reasons, such that the product must be appropriately rotated about an axis perpendicular to the longitudinal axis.
  • the skin side is down and the fish fillets are fed head-on forward.
  • the turning can also be necessary for other products, such as chicken fillets or the like, ie in particular soft products, for example to bring a fat side from top to bottom or a narrow product area from the forward current position to a trailing position.
  • an aid is used with the fish fillets on the basis of the above-mentioned example, so that the fish fillets fall directly onto the skin side after separation from the midbone, so that only turning about the axis perpendicular to the longitudinal axis is required to remove the fish fillets to change their direction tail in advance in head.
  • these aids are unreliable, so that errors often occur, which disturbs the turning process.
  • devices or devices for turning in use which are designed to turn the products about a single axis, ie either about the longitudinal axis or about the axis perpendicular to the longitudinal axis and set up.
  • For turning around the longitudinal axis for example DE 40 22 461 C2 is mentioned here.
  • a disadvantage of such devices however, that for each turning operation, so turning around the longitudinal axis on the one hand and the turning about the axis perpendicular to the longitudinal axis on the other hand, separate turning elements are provided. This increases the
  • Transport direction swiveling For example, if a product is on the meat side on the lower conveyor belt, the transport unit is rotated 180 ° so that the product falls on the top and bottom conveyor belts, with the skin side down. At the same time, the rotation through 180 ° causes the direction of travel from tail side ahead in head side.
  • This known solution is very complex with a plurality of moving parts and requires on the one hand a very large amount of space. On the other hand, the positioning of the products on the discharge element is not optimal.
  • the turning station comprises a turning drum, which is arranged in the transport direction T of the fish fillets between the feed and the Ab representativeelement, which defined by the Ab representativeelement
  • Planning the products Per perforation is understood to mean any type of passages, for example bores, slots or the like, which allow the products to be sucked onto the lateral surface of the turning drum.
  • Feeding be turned or carried away on the Ab contributingelement.
  • a preferred embodiment is characterized in that the discharge element, which is likewise designed as a belt conveyor, is arranged below the turning drum. This ensures that the falling off of the turning drum fish fillets "land" reliably on the discharge.
  • At least one roller is disposed between the turning drum and the discharge element, which is spaced both to the turning drum and to the discharge element.
  • a preferred embodiment of the invention is characterized in that a roller element is arranged as a guide element between the feed element and the turning drum.
  • a roller element is arranged as a scraper element in the region of the roller.
  • the roller is arranged and arranged such that the fish fillets are guided about 270 ° around the turning drum.
  • This means that the roller is arranged offset from the vertical center axis A greater than 180 ° and less than 270 °.
  • This wiper element ensures that the fish fillets reliably detach from the turning drum and fall over the roller onto the discharge element.
  • Fig. 1 is a schematic representation of a turning station according to the invention.
  • the turning station or device shown is used for turning fish fillets in fish processing plants.
  • the turning station can also be operated as a single unit, even for other products.
  • the apparatus 10 shown schematically in FIG. 1 and only partially, comprises a feed element 11 for feeding fish fillets (also referred to below as product) 12 into the area of a turning station 13, the turning station 13 and a discharge element 14 for conveying the turned products 12 .
  • the Zuflihrelement 1 1 and the discharge element 14 are formed in the embodiment shown as a belt conveyor, wherein the conveyor belt 15 and 16 is guided around deflecting and / or drive rollers 17 and 18 respectively. Both the feed element 1 1 and the discharge element 14 may be formed in another known manner, for example as a chute or the like.
  • the turning station 13 is arranged between the feed element 1 1 and the discharge element 14 such that the products 12 can be reliably transferred.
  • the turning station 13 virtually establishes the connection between the feed element 11 and the discharge element 14.

  • the removal element 14 is arranged with reference to the product flow behind the turning drum 19. This means that the products 12 are first fed to the turning station 13 after the feed element 11, in order then to be passed on to the discharge element 14.
