Abstract

The feed for the first trimming etc. station consists of a number of pairs of opposed vertical flexible belts spaced apart and the fish is fed to a position above them between a pair of horizontal tilted belts forming a trough. The rollers on which these belts are running are mounted on shaft which can be rocked from a closed trough position to an open base form, bearings at the lower ends being mounted on axially parallel bars attached via linkages to linear actuators. These same actuators operate through the linkages a number of pairs of bell cranks whose lower ends move inwards as the trough opens to form an intermediate catching frame immediately above the entry to the vertical belt conveyor the lengths of the arms being such that the frame is at any desired angle to the horizontal in the axial direction. Smooth transfer of the fish to the vertical conveyor in the desired attitude. Automatic, the operation of the actuators is initiated by the head of the fish striking a switch lever mechanism so opening the trough at the correct instant and the control system closing the trough and opening the lower levers also automatically.

Description

Fish input device, especially for larger fish.

The invention relates to a fish input device, in particular for larger fish for feeding fish processing systems.

Decisive for the quality processing of fish of different kinds Dimensions is their orderly input. There are a number of facilities for this known, one of which consists of a channel-like, swiveling fish support, in the area of which a pair of grippers and a controlled headrest are arranged. The pair of grippers is brought up to the fish via a rotatable control disc. At the same time as the fish is adjusted, the head support is adjusted. Devices of similar design have an arched fish rest Trough with a trapezoidal cross-section.

In another device for loading fish processing machines the fish is fed to a fish collector over several straightening stretches. This exists from a funnel-shaped container and an oval tube, which is used during the fish removal is vibrated. There is a spring-loaded driver at the end of the tube.

With the support of the carrier, the fish are picked up individually and placed in open bowls.

The feed speed has a channel-like design Fish pad and the arched tub, due to the different Mucus content and the different scale structure of the fish irregularities on, whereby the throughput is reduced. The fish collector is only for Suitable for fish of a certain thickness. The purpose of the invention is to remove it these defects are caused by a mechanical one that is independent of the external condition of the table Feed.

The invention is based on the support, one of the fish feeder to develop dependent fish input, whose movement mechanisms for the opening and closing both the centering and the transition of the fish in take on a vertical transport system.

According to the invention there is a separately driven one above the fish input Band pair, which forms a trough open at the top. It is pivoted, is operated via lifting elements and is connected to movement mechanisms0 The movement mechanisms are mounted and designed in such a way that they are in the open position of the band pair form an inclined intermediate support. To open and close the fish input Pneumatic drives are available as lifting elements, which are driven by an adjustable Head stop can be triggered via a switch.

The movement mechanisms are made up of several, articulately connected to one another Assembled levers and connecting links and pivot axes to the pair of belts connected.

They run between the belt pairs of a vertical transport system.

Furthermore, the movement mechanisms along the fish input arranged opposite one another or offset from one another. Their side levers are advantageously roughened in the lower area or have sharp edges.

The fish arrives at the same distance, regardless of the external shadow into the fish input, whereby a specified throughput is guaranteed. The opening and closing process takes place depending on the fish supply.

Fish of various species and diets can eat without change the floating position can be transferred to a vertical transport system.

The invention is explained in more detail by means of an exemplary embodiment with drawings explained. They show: FIG. 1: a schematic longitudinal section of the fish input Representation, Fig. 2: a section A-A of Fig. 1 in the closed position of the fish input, Fig. 3: a section A-A of Fig. 1 in the open position of the fish input and closed position the intermediate edition.

Two separately driven conveyor belts run above the fish feeder 1; 1 ', which in the closed position form an upwardly open trough. The conveyor belts 1; 1 'are about pivot axes 2; 2 'with a lever system underneath tied together. The lever system comprises a plurality of connecting levers 3 and side levers 4; 4 '. the latter are arranged in pairs opposite one another and on supports 5; 5 'rotatably attached. They run between the pairs of bands that form the fish input 6; 7; 8 of a vertical transport system.

Furthermore, the connecting lever 3 by connecting members 9 to the Pivot axes 2; 2l of the conveyor belts 1; 1 'connected. Connect in the upper part separate and rotatably mounted axes 10; 10 'the drive rollers 11 and pulleys 12 of the two conveyor belts 1; flta The fish 13 arrives at the same distance over feed belts 14 onto the conveyor belts 1; 1'. the Conveyor belts 1; 1 'take over the introduced fish 13 and move it above the fish input to an adjustable head stop 15. Touches the head of the Fish 13 the head stop 15, so a switch, not shown the pneumatic drives are actuated and their pistons 16; 16 'briefly on and aiis

When retracting the piston 16; 16, the conveyor belts 1; 1' about their axes 10; 10 pivoted outwards, with the between the conveyor belts 1; 1 'lying fish 13 falls down. At the same time, by swiveling in the Side lever 4; 4 ′ an inclined intermediate support 17 is formed which centers the fish 13 receives, the pistons 16; 16 'extended again, the intermediate support opens 17 and the conveyor belts 1; 1 'take their starting position again a. The fish 13 slides along the side lever 4; 4t in the vertical transport system, where he of the band pairs 6; 7; 8 detected and transported to the processing tools will.

Depending on the size of the fish 13 to be processed, the head stop 15 can be moved.

Instead of the pneumatic drives, hydraulic or electric drives are used.
