Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention provides a method for transporting flat fish and for guiding the flat fish while keeping them aligned, regardless of the size of the fish. , and an apparatus for carrying out the method.

[Prior art]

A method of this kind is described in British Patent Specification No. 928733.
Disclosed in the issue. According to this method, flat fish are aligned by orienting their contours. To this end, the device has a centering mechanism with four centering pins and one head guide that are adjustable and controllable relative to each other. The device is controlled in such a way that the engagement of the detection elements with the external contours of the fish to be treated takes place independently of the size of the fish, provided that the fish are of the same species. Separation of the head and abdominal cavity is performed at the position obtained by contact with the detection element.

A wide variety of flat fish are commonly caught in relatively narrow areas,
It is especially caught in the waters of the northern hemisphere. In conjunction with the high throughput of modern no-treatment machines, there is a demand for universal no-treatment machines capable of processing multiple species of fish in terms of processing economy. Such universal fish treatment cannot be achieved with conventional centering methods, or at least can only be achieved with costly modifications. This is because an integrated control of the centering elements is carried out with the aid of a gear wheel 1, which has to be adapted to the special conditions of the contour of one type of flat fish.

Accordingly, there is a need for a method and apparatus that allows flat fish to be aligned and guided largely independent of fish type and size.

[Summary of the invention]

The present invention provides a device for aligning flat fish independently of the size of the fish and for transporting and guiding the flat fish in alignment.

Its key advantage is that it takes advantage of anatomical features common to all flatfish species for precise alignment and positioning without the need for any readjustment or replacement of mechanical elements. This is particularly the case. By taking advantage of the anatomical features of the flat fish, we have developed techniques such as traps to open the kidneys for blood removal, evisceration, and instruments used to precisely dispose of the abdominal cavity. An advantage is also obtained that the alignment is based on features found directly in the vicinity of the operating range.

In a particularly preferred example for the feed function.

A gripping rail is disposed within the support surface and is provided with a gripping edge extending upwardly beyond the support surface.

The same objective is achieved in a further preferred embodiment in which the presser edge of the presser element is formed as a gripping edge of a gill flap gripper. In this case, a guide rail can be provided which is arranged in the same plane as the gripping edge and which can be moved over the flat fish against the force of the spring and which reaches the processing position of the fish.

To counter the risk of twisting the fish due to contact with parts other than the fish's center of gravity while the fish is being carried in a direction perpendicular to its longitudinal axis, the fish-carrying element must be It has a support plate that contacts the hind flank of the fish. That's it υ
, so that the torque that can occur while transporting fish is absorbed.

Besides the line contact of the edge of the fish shoulder girdle arc and the presser edge of the presser element along the gill lid, the flat fish rump will be further supported.

According to a further advantageous embodiment of the invention, the carrying element has two carrying strips. Each strip has a holding edge adapted to the cross-sectional profile of a medium-sized flat fish fed in a direction perpendicular to the longitudinal axis for processing and against the force of a spring. Can be placed on flat fish at the same time.

therefore.

This is advantageous because it is possible to stabilize the position of flattened fish that are being transported laterally.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to one drawing.

In the drawing, a feed section 1 is installed inside a fish processing machine. The feeding section 1 has a support surface 2 for supporting a flat fish 3. A gripping rail 5 is arranged in the support surface. This gripping rail 5 extends in the longitudinal direction of the fish processing machine to a processing section (not shown). The gripping rail 5 has a gripping edge 6. This gripping edge 6 is formed by slightly bending upwards a part of the support surface 2 and extends upwardly beyond the support surface 2 . A holding element 7 is provided above the support surface 2 and is held down by the force of a spring 9.

This holding element T can be pivoted about an axis 8 which is fixed to a frame (not shown). The presser element T has a presser edge 10 . This presser edge 10 is brought into contact with the flat fish 3 and extends parallel to the gripping rail 5. Presser foot edge 1
0 can move in a plane approximately perpendicular to the support surface 2,
A flat fish is encountered just behind the grip edge 6. The presser edge 10 is shaped to suit the cross-section of a flat fish to be processed of medium dimensions.

The device also has a mechanism 11 for carrying the flat fish 3.

The mechanism 11 includes a ride element 12 having a ride edge 13 . The riding edge 13 is brought into contact with the flat fish. The rest edge 13 is formed approximately corresponding to the presser edge 10 of the presser element T and extends approximately parallel to the gripping rail 5. The resting element 12 is in a plane extending in front of the presser edge 10 of the presser element T.

The support surface 2 is guided along a movement path 14 by a suitable mechanism that describes a vertical rectangle. Rectangular motion path 14
The upper side represents the return motion vector of the mounting element 12 in the lifted position, the instantaneous side represents the downward movement vector of the mounting element 12 onto the flat fish, and the lower side represents the carrying motion vector of the mounting element 12. represents. The motion vector is determined by the ride element 12 at the end position (not shown) of the processing section.
approaches the release motion vector. A support plate 15 extending substantially parallel to the support surface 2 is arranged on the rear part of the one-seat edge 13.

In the embodiment shown in FIG. 2, the gripping edge 6 is moved away from the support surface 2 to the presser edge 10 of the presser element 7. The gripping edge 6 is designated here by the reference numeral 16. In this embodiment, a guide rail (not shown), which is arranged flush with the gripping edge 16, can be moved to the treatment section against the force of a spring.

Next, the operation of this device will be explained. The flat fish 3 to be processed is placed on the support surface 2 in front of the gripping edge 6 in any suitable manner, for example by hand, and is placed on the support surface 2 in front of the gripping edge 6 of the gripping rail 5.
Be sure to grasp the back of the gill 4 edge of the shoulder girdle arc first.

It is moved according to the vector sequence 17 shown in FIG. The flat fish 3 then reaches under the holding element 7. Due to the shape of the presser edge 10 and the edge support of the shoulder girdle arc on the gripping edge 6, the flat fish 3 is held in a position determined with reference to the position and orientation of its longitudinal axis. Ru. In this position, the flat fish 3 is lifted up by the mounting element 12 which has been lowered onto the fish 3 and is carried away from the area of the holding element 7. Stabilization of the position of the flat fish 3 and the support plate 15 located on the mounting element 12
A reliable loading function is achieved.

The support plate 15 supports the rear flank of the fish 3.

The flat fish 3 are released in the processing position because the mounting element is controlled to lift the mounting element in the processing position and release the fish.

In a second embodiment of the apparatus shown in FIG.
In order to feed the flat fish 3, the nose is pushed toward the top side of the holding element I in the longitudinal direction of the fish.

The hold-down element 7 is lifted against the force of a spring (not shown). This action continues until the shoulder girdle arc of the gills passes past the gripping edge 16. By then retracting the gripping edges 16, the gripping edges 16 position the flat fish 3 with respect to the position of the fish edges by gripping their fish edges. Due to the gripping edge 16 being adapted to the cross-sectional shape of the flat fish 3, the position of the longitudinal axis of the fish 3 is likewise fixed. The fish are then transported as described with reference to FIG.

The mounting element 12 can take various forms.

In other words, a second ride strip can be provided in conjunction with the ride element 12 that has been described so far. The belt grips the widest part of the flat fish and one part of the fish, bringing it together. The mounting edge 13 can also be provided with nails.
