[0045] Further preferred and/or suitable features and embodiments of the invention arise from the sub-claims and the description. Particularly preferred embodiments are explained in more detail with reference to the enclosed drawings. To avoid repetition, the method according to the invention is explained in more detail below together with the fish feed-in device according to the invention. The drawings show:

[0047] FIG. 2 a perspective view of the transverse conveyor according to the invention with a transfer device,

[0048] FIG. 3 a partial extract of the fish feed-in device shown in FIG. 1,

[0050] FIG. 5 a perspective, detail view of the transverse conveyor and a transfer device,

[0051] FIG. 6 the detail view shown in FIG. 5 from a rear perspective, and

[0052] FIG. 7 the detail view shown in FIGS. 5 and 6 in a view from below.

[0053] FIG. 1 shows a perspective view of a fish feed-in device 10 according to the invention. As an example, the fish feed-in device 10 is configured with three feeder devices 11 and eight longitudinal conveyors 12. By means of the longitudinal conveyors 12, fish 13 (not shown in FIG. 1) are guided to several fish-processing devices. The fish-processing devices, for example slaughtering and/or gutting machines, are not shown in the drawing for reasons of clarity. The number of fish feed-in devices 10 shown, and the number of longitudinal conveyors 12, is evidently not restricted to the number shown in FIG. 1 but purely exemplary. As explained initially, one essential advantage of the present invention is that the number of feeder devices 11 and the number of longitudinal conveyors 12 and fish-processing machines connected thereto, may be configured arbitrarily according to application.

[0054] The fish feed-in device 10 according to the invention comprises a transverse conveyor 14 which is configured to convey the fish 13 transversely to their head-tail orientation in the transverse conveying direction 15. The head-tail orientation is based on a theoretical axis running from the head to the tail of the fish 13. The fish 13 are conveyed by means of the transverse conveyor 14 transversely to this axis in the transverse conveying direction 15. The transverse conveying direction 15 and said axis here form a right angle or approximately a right angle. The orientation of the fish 13, i.e. the direction in which the head of the fish 13 is pointing, is in principle arbitrary. Preferably however, the fish are oriented on the transverse conveyor 14 such that they are then conveyed tail first by means of the longitudinal conveyor 12.

[0055] FIG. 2, which shows a perspective view of the transverse conveyor 14 according to the invention with just one transfer device 16, reveals that the transverse conveyor 14 comprises a plurality of receptacles 17 each configured to receive an individual fish 13. The length of the receptacles 17 is greater than the greatest length of the fish 13. Preferably, the receptacles 17 have edge elements 18 which protrude upward relative to the bottom of the receptacles 17, so that the fish 13 are conveyed securely by the receptacles 17 in the transverse conveying direction 15. Furthermore preferably, the bottom is formed inclined towards the middle of the receptacles 17, so that the fish 13 are automatically centred in the receptacles 17 under the effect of gravity. The transverse conveyor 14 has a drive unit 19 which is configured so as to be controllable and comprises for example one or more controllable servomotor drives.

[0056] As shown as an example in FIG. 1, the fish feed-in device 10 according to the invention comprises at least one feeder device 11 configured to supply fish 13 to the receptacles 17 of the transverse conveyor 14. The fish 13 are preferably transferred to the feeder devices 11 manually by operators, and said feeder devices 11 then fully automatically feed the fish 13 into the receptacles 17 of the transverse conveyor 14. The feed devices 11 and the receptacles 17 are configured such that each of the receptacles 17 can be supplied with one of the fish 13.

[0057] Furthermore, the fish feed-in device 10 according to the invention comprises several transfer devices 16 which are configured for selective transfer of the fish from the transverse conveyor 14 to the respective longitudinal conveyor 12 arranged upstream of the fish-processing devices.

[0058] By means of a control device (not shown in the drawing), the at least one feeder device 11, the transfer devices 16 and the conveying speed of the transverse conveyor 14 are controlled on the basis of at least one predefined distribution specification. In other words, the control device is designed and configured to control or regulate the above-mentioned components.

[0059] Preferably, the feeder device 11 shown as an example in FIG. 4 comprises at least one clocking flap element which is movable under control. This is configured to control, by means of a clocking control signal generated by the control device, the infeed of fish 13 to one of the receptacles 17 at a preselected output time. In other words, the control device is designed and configured such that one of the fish 13 is transferred to the respective receptacle 17 passing the clocking flap element 20 by means of the clocking flap element 20, insofar as the infeed of fish 13 is provided according to the predefined distribution specification, so that the receptacle 17 is supplied with one single one of the fish 13.

[0060] Advantageously, the feeder device 11 comprises a guide plane 21 which is arranged inclined such that under the effect of gravity, the fish 13 automatically come to lie in a first retaining area 22 in front of the clocking flap element 20 when the latter is in its closed position, and automatically move in the direction of the transverse conveyor 14 into the respective receptacle 17 when the clocking flap element 20 is in an open position. In FIG. 4, the docking flap element 20 is shown in the closed position.

[0061] According to an advantageous development of the invention, the feeder device 11 comprises a storage flap element 23 which is movable under control. The storage flap element 23 together with the clocking flap element 20 forms a flap cascade 24. The fish 13 are brought via the guide plane 21 into a waiting area 25 in front of the storage flap element 23. When the storage flap element 23 is in an open position, the respective fish 13 moves under the effect of gravity into the first retaining area 22 and comes to rest in front of the clocking flap element 20 which is in the closed position, until this moves into the open position and the fish 13 enters the respective receptacle 17 as described above.

[0062] Advantageously, the control device is configured to control the flap cascade 24 such that when the clocking flap element 20 moves from the open position to the closed position, the storage flap element 23 moves from the closed position to the open position, and vice versa. The control device is consequently configured, in knowledge of the inertia behaviour of the fish 13, to take account of the delays occurring such that the opening process of the storage flap element 23 begins for example even while the clocking flap element 20 is still in the open position. It is however ensured that the clocking flap element 20 is already in the closed position or has already closed so far that the respective fish 13 comes to rest in the first retaining area 22. In this way, it is ensured that the fish 13 stops temporarily at least in the first retaining area 22.

[0063] According to a preferred embodiment of the invention, a sensor means 26 for fish detection is arranged in the region of the storage flap element 23. The sensor means is configured and designed to detect the presence of a fish 13 in the waiting area 25 in front of the storage flap element 23, and report this to the control device.

[0064] Advantageously, several of the feeder devices 11 are arranged next to and offset to each other in the transverse conveying direction 15 by at least a width of the receptacle 17. The number of feeder devices 11 arranged offset can be selected freely depending on need. As shown as an example in FIG. 4, the fish feed-in device 10 according to the invention may comprise four of the feeder devices 11. The feeder devices 11 are preferably arranged each offset by the width of a receptacle 17, so that successive receptacles 17 can be supplied without interruption.

[0065] The receptacles 17 of the transverse conveyor 14 preferably form a circulating conveyor. The receptacles 17 forming the transverse conveyor 14 are each guided via at least two drive wheels 27, each driven by the drive unit 19. Particularly preferably, each of the receptacles 17 is configured so as to be pivotable about a transverse axis 33. In other words, the receptacles 17 and the transverse conveyor 14 are configured such that the receptacles 17 can be tilted by means of the control device. Due to the oblique position of the receptacle 17, the fish 13 present in the respective receptacle 17 therefore slides out under the effect of gravity and is guided onto the respective longitudinal conveyor 12 in the region of the transfer devices 16.

[0066] FIG. 5 shows in detail, in a perspective view, the transverse conveyor 14 and one of the transfer devices 16. The transfer devices 16 each comprise an ejecting diverter 28 which is designed and configured to pivot the respective receptacle 17 from a fish transport position into a fish ejection position by means of a transfer control signal generated by the control device. The fish ejection position corresponds to the oblique position described above of the respective receptacle 17, wherein the drawing only shows the fish transport position.

[0067] A preferred development is characterised in that the ejecting diverter 28 comprises a pivot guide 29 which is configured so as to be controllable by means of the transfer control signal. The pivot guide 29 comprises pivot elements 30. In the fish transport position, as shown in FIGS. 4 and 5, the pivot element 30 is oriented such that the receptacles 17 are guided in the transverse conveying direction 15. If the pivot element 30 is pivoted by means of the transfer control signal into a lower position (not shown in the drawing), the rear part of the receptacle 17 relative to the transverse conveying direction 15 is tilted about the transverse axis 33, in that the rear part of the receptacle 17 is guided via the pivot element 30 and the deflection guide 31 such that the respective receptacle 17 is brought into the fish ejection position.

[0068] Preferably, the transfer devices each comprise guiding means 32 in the region of the ejecting diverter 28, which means are configured to transfer the fish 13 from the receptacles 17 in the fish ejection position onto the respective longitudinal conveyor 12 under the effect of gravity.

[0069] FIGS. 6 and 7 also show the detail view shown in FIG. 5 from a rear perspective and in a view from below respectively.

[0070] According to a further advantageous embodiment of the invention, it is provided that the transfer devices 16 each comprise fish occupation sensors (not shown in the drawing). The fish occupation sensors are configured to report to the control device whether the respective longitudinal conveyor 12 is occupied by a fish 13 or is free in the region of the transfer device 16.

[0071] Preferably, the control device is configured, on the supply of fish 13 to the receptacle 17, to assign said receptacle 17 to one of the fish-processing machines on the basis of the predefined distribution specification, and to determine an allocation specification. Furthermore, the control device is in particular configured to determine the positions of the receptacles 17 and determine the respective output times on the basis of the allocation specification and the determined positions of the receptacles 17. The positions may be determined for example by a reference sensor which detects when a receptacle 17 passes a reference position. Since the control device is also configured to predefine and set the conveying speed of the transverse conveyor 14, it is furthermore preferably configured to determine the positions of the receptacles 17 on the basis of the position signals supplied by the reference sensor and the conveying speed.

[0072] Advantageously, the control device is configured to determine the take-up performance of the fish-processing machines and/or the occupation states of the transfer devices 16, and from this determine an actual take-up performance for each fish-processing device.

[0073] According to a further preferred embodiment of the invention, the control device comprises a comparison unit which is adapted to compare the actual take-up performance of each fish-processing device with a predefined nominal take-up performance assigned to the respective fish-processing device, and if at least one of the actual take-up performances falls below the respective assigned nominal take-up performance, to adapt the predefined distribution specification such that the respective nominal take-up performance is at least temporarily reduced.

[0074] Preferably, the control unit is furthermore configured to determine a total actual take-up performance as a sum of the actual take-up performances of the fish-processing machines, and to control the conveying speed of the transverse conveyor 14 such that the receptacles 17 are supplied without interruption.
