IN-FEEDING AND OBJECT RELEASE APPARATUS

Abstract

The present invention relates to a method and a device for individual feeding of fish into a processing line. Such method and device may, for instance, be used for receiving, gilling and gutting freshly caught fish in a processing line on board a fishing vessel. For instance, the in-feeding apparatus and method may be used to increase the value of the fish by speeding up the time until the fish is chilled for storing.

8. The apparatus according to claim 1, the object receiver has a sensor above or in one of the sides of the chamber.

9. A method for feeding objects to a process line, the method comprising: feeding a objects in an object receiver, detecting the object by a sensing means in object receiver, determining an object space on a v-shaped conveyor consisting of two individual continuous conveyor belts by a computing means, releasing the object from the object receiver by a releasing means onto the v-shaped conveyor, the conveyor belts of said v-shaped conveyor further comprising slide resisting means on the surface of the belt to prevent the object from sliding as they are released onto a moving v-shaped conveyor belt, and releasing the objects from the v-shaped conveyor by dropping the object from the out-feed end. to feed objects from the apparatus to a process line, one object at the time, at high speed.

10. The method according to claim 9, wherein the objects are feed from the apparatus to a process line, one object at the time.

11. The method according to claim 9, wherein the step of releasing the objects from the v-shaped conveyor comprises dropping the object in a relatively horizontal position from the out-feed end by means of one of the two belts forming the v-shaped conveyor being longer than the other belt.

12. The method according to claim 9, further comprising the step of pre-processing objects at one or more working stations.

13. The method according to claim 12, further comprising the step of a worker releasing the object into the object receiver, said object receiver is positioned below each of the one or more workstations.

14. The method according to claim 9, wherein the computing means assigns a next free object space to the nearest object in an object receiver.

15. The method according to claim 14, wherein the computing means calculates and assigns free object spaces to items in the one or more workstations to minimize the number of free object spaces at any time on the v-shaped conveyor belt.

16. The method according to claim 9, wherein a sensor above or in one of the sides of the object receiver detects the presence of a fish being placed in the object receiver by the worker.

17. The method according to claim 9, wherein the object is whole fish.

18. The method according to claim 12, wherein the pre-processing step refers to one or more of sorting, slaughtering, gilling, gutting whole fish.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention will become more fully understood from the detailed description given hereinafter and the accompanying drawings which are given by way of illustration only, and thus, are not limitative of the present invention, and wherein:

[0033] FIG. 1 is a side view and a cross section of the apparatus of the present invention,

[0034] FIG. 2 is a top view of the apparatus of the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0035] FIG. 1 shows a side view and a cross section of the apparatus of the present invention. It is an apparatus for feeding objects such as fish onto to a process line. The figure shows an embodiment of a worker 1 at a workstation 2. When the worker 1 has finished processing the fish 3, such as gilling and/or gutting the fish the worker releases the object into an object receiver 4. The object receiver is a chamber below the work station and it has a sensor 8 above or in one of the sides of the chamber to detect the presence of an object/fish being placed in the object receiver by the worker 1. In FIG. 1A, an object/fish 3 is shown on the workstation 2 and in the object receiver 4. The object receiver further comprises a releasing means for releasing objects from the object receiver. In the embodiment shown in FIG. 1, the bottom of the chamber is a plate 5 and a piston 6 behind the plate 5 pushes the plate and thereby the object out of the chamber and onto a v-shaped conveyor belt 7. In FIG. 1B, the object has been released from the object receiver 4 and onto the v-shaped conveyor belt 7. The v-shaped conveyor consists of two individual continuous conveyor belts 7a and 7b. The two individual continuous conveyor belts of the v-shaped conveyor 7 have slide resisting means on the surface of the belts. This is a rough material implemented on the surface or the surface is made from such a material in order for the determined item space on the moving belt to catch the fish as it is released onto the belt and carry the fish away from the object receiver without the fish sliding over to other item spaces. One of the two belts forming the v-shaped conveyor is longer than the other belt at the out feed end of the belt (not shown in the drawing). A computer calculates and determines empty and full item spaces on the v-shaped conveyor belt. Therefore, when a fish has been released onto an object receiver, it is kept there until the computer has assigned the next free object space on the v-shaped conveyor belt to the fish and when that free space is positioned below the object receiver the object is released from the object receiver and onto the belt.

[0036] FIG. 2 shows a top view of the apparatus of the present invention. The figure shows an embodiment of workers 1 at seven workstations 2. When the worker 1 has finished processing the fish 3, such as gilling and/or gutting the fish the worker releases the object into an object receiver (not shown in the drawing). The object receiver is a chamber below the work station and it has a sensor (not shown in the drawing). A continuous transport and distribution conveyor 9 is implemented for transporting objects to workstations is shown consisting of two belts running in opposite directions. The arrows indicate the direction of transport and diverting means 10 divert the items between the conveyor belts for circulating the fish until a worker 1 picks up a fish for processing. The v-shaped conveyor belt 7 is positioned under the continuous transport and distribution conveyor 10 and only the longer belt 7b of the v-shaped conveyor belt 7 is shown at the out-feed end of the belt extending over the take-away conveyor belt 11.
