Abstract

A fish feed-in device (1) for feeding fish (9) to a fish processing device (7) comprises a delivery conveying means (3) which is equipped with a controllable positioning drive (35) and a controllable conveying drive (36). The delivery conveying means (3) can be moved by the controllable positioning drive (35) into a first state (301) released by the fish (9) in a deposit space (11), into a second state (302) for grasping, centered holding and conveying of the fish (9) accessing said fish in the deposit space (11) and, in cooperation with the controllable conveying drive (36), into a third state (303) which releases the fish (9) after conveying at a fish delivery point (42) which is defined by a controlled delivery time with associated controlled fish delivery speed.

First claim

The invention claimed is:

1. A fish feed-in device, configured for the automatic serial receipt and delivery of fish for feeding the fish to a fish processing device, comprising a deposit space receiving each fish in the longitudinal position, a delivery conveying means, which grasps and holds the fish in said longitudinal position, with which the fish can be conveyed for successive delivery in the longitudinal position in a delivery conveying direction corresponding to the longitudinal position,
characterized in that the delivery conveying means is arranged and designed for immediate access to a fish located in the deposit space and is configured with a controllable positioning drive and a controllable conveying drive, which are controllable with at least one conveying control signal that is definitive for feeding the fish in an adjusted manner to a conveying facility of a fish processing device, wherein the delivery conveying means can be moved by the controllable positioning drive into a first state released by the fish in the deposit space, into a grasping second state for grasping, centred holding and conveying of the fish in the deposit space and, in cooperation with the controllable conveying drive, into a third state which releases the fish, after conveying, at a fish delivery point which is defined by a controlled delivery time with associated controlled fish delivery speed.

2. The fish feed-in device according to claim 1 , characterized in that the positioning drive and the conveying drive of the fish feed-in device are connected to an electrical control means, which can be actuated by at least one said conveying control signal and which controls the discharge speed and the discharge time of each fish.

3. The fish feed-in device according to claim 1 , characterized in that the fish delivery point is determined by a delivery conveying path which starts at a reference point that is assigned to a uniform fish position and ends with a defined conveying length at the fish delivery point.

4. The fish feed-in device according to claim 3 , characterized in that a position sensor means is assigned to the reference point, which position sensor means determines the position of a defined body point common to all fish for each fish and generates a corresponding said conveying control signal.

5. The fish feed-in device according to claim 4 , characterized in that the position sensor means is configured for detecting uniform access points of the fish which are assigned to the common body points, said access points being graspable with a processing conveying means of a fish processing device.

6. The fish feed-in device according to claim 1 , characterized in that the delivery conveying means has two conveying elements which are formed by a pair of flank conveyors, which are adjustable in distance by the positioning drive and can be moved apart into an opening distance transverse to the fish conveying direction to establish the first state and the third state and can be moved towards each other into a closing distance transverse to the fish conveying direction to establish the second state, wherein in the second state they come to rest against the flanks of a fish in such a manner that the fish come to lie in a position with an upright fish symmetry plane.

7. The fish feed-in device according to claim 1 , characterized in that the deposit space has a deposit means which is formed by a collecting means with a resting point which receives a single fish at which the fish comes to rest during the first state and also on establishing and reaching the second state of the delivery conveying means.

8. The fish feed-in device according to claim 1 , characterized in that the deposit space has a profile adapted to a cross-sectional profile of the fish, by which the fish can be placed in a centred position with an upright fish symmetry plane.

9. The fish feed-in device according to claim 1 , characterized in that the delivery conveying means has a support conveying element arranged along it which supports and orients the fish during delivery conveying.

10. The fish feed-in device according to claim 1 , characterized in that the fish feed-in device has a guiding device which orients the fish for delivery and during delivery.

11. The fish feed-in device according to claim 10 , characterized in that the guiding device is formed by a sliding guide rail.

12. The fish feed-in device according to claim 10 , characterized in that the guide device has an upper guiding device which is formed by two mutually opposing sliding guide walls.

13. The fish feed-in device according to claim 10 , characterized in that the guide device is designed with a discharge mechanism which delivers the fish before or at the fish delivery point, controlled by the fish feed-in device in the event of an operational malfunction.

14. The fish feed-in device according to claim 1 , characterized in that the fish feed-in device has a transfer section which protrudes freely on the delivery conveying means.

15. The fish feed-in device according to claim 1 , characterized in that the fish feed-in device is connected to a controllable loading device which is designed for serially conveying fish into the deposit space.

16. The fish feed-in device according to claim 1 , characterized in that the fish feed-in device, for loading the deposit space with fish, has a loading means which is formed by a load conveyor that opens into the deposit space and is configured in such a manner that the fish conveyed up to it for loading can be conveyed into the deposit space individually and successively with a direction-oriented longitudinal position.

17. A fish transfer system, configured for serially transferring fish to a fish processing device, comprising a fish feed-in device and a processing conveying means, which serially transfers the fish from the fish feed-in device at a fish receiving point, said processing conveying means having fish carrier elements spaced along a processing conveying path, said carrier elements each being configured at the fish receiving point for receiving, and along the processing conveying path for transporting a fish, wherein a fish delivery point of the fish feed-in device is assigned to the fish receiving point, characterized in that the fish feed-in device is formed by the fish feed-in device equipped with the delivery conveying means according to claim 1 .

18. The fish transfer system according to claim 17 , characterized in that the electrical control means is configured in such a way that the at least one conveying control signal detects the speed of the fish carrier elements as well as their chronological passing of the fish receiving points.

19. The fish transfer system according to claim 18 , characterized in that a receiving sensor means connected to the electrical control device is arranged at the fish receiving point, said sensor observing the fish transfer and transmitting a corresponding fault control signal in the event of a malfunction.

20. The fish transfer system according to claim 18 , characterized in that a discharge means connected to the electrical control device is arranged on the processing conveying means, said discharge means discharging a fish which is conveyed by the processing conveying means but is in the wrong position.

21. The fish transfer system according to claim 17 , characterized in that the electrical control means is configured in such a manner that the fish delivery speed at the fish delivery point is correlated with the
