SU96721A1 - Device for orienting the flow of fish heads forward - Google Patents

Description

The subject of the invention is a device for orienting the flow of fish heads forward for sorting, laying and similar machines.

At present, the orientation of the flow of fish in the canning industry, in the sorting, laying and filing devices is carried out manually.

The described device is intended to ensure a continuous process of orientation of the fish.

A feature of the device is that it is made in the form of a vertical corrugated cone, the continuation of each corrugation of which is a system of guide plates, on each of which the interleaving with the fish shines through two beams of light acting and the cathodes of two successive photoelectric cells, in the case of incorrectly oriented fish transmitting impulse to the executive relay, dropping the fish from the main plates to the overturning inclined plates.

FIG. 1 shows a view of a corrugated cone device; on

FIG. 2 shows a guide plate, a light source and a photo relay; in fig. 3 - system p / shstin device.

The device includes a vertical corrugated cone /, a fish pump mounted on the outlet and a diffuser 2, main guiding plates 3 made with bend 4 and protrusions 5 h of fish snuggling along this section of the plate, turning the inclined plates 6, additional plates 7, having the form of an obtuse angle, two light sources 8, two photo relays 9, and an executive relay (not shown in the drawing).

The fish from the fish pump enters a vertically positioned diffuser 2, on which a corrugated cone is fastened, orienting the irregular stream of fish to a number of precisely directed streams.

Along the corrugated cone, the fish evenly slide to its periphery, from where they fall on the main guide plates 3, which are a continuation of each corrugation of the cone 1.

At each main part of the fish, two rays of light are exposed to light, acting on the cathodes of the photocells.

In order to detect an incorrectly running fish, it is used that the head part of the fish within one species is always a fraction of the tail fin and, moreover, the tail fin in the overwhelming majority of fish is more transparent than the head part. If the fish goes correctly, i.e. with the head forward, the executive relay, Bypo.lnenp0e in the form of a plate which clashes the fish, driven by ot of the solenoid, is not Wed, and the fish will pass, go ahead. .

In the TBM case, if the fish goes XBOctdsbiM with a fin forward, the photo relay 9 is triggered and the executive relay resets the fish and the inclined tilting plate 6, where the fish turns over, follows the head forward along the additional plate 7 and joins the common flow.

The working beam of light rays illuminating the cathode of the first photo-element is directed perpendicularly to the movement of the fish. A tuft of pffe rays of the caudal fin, but significantly narrower than the head of the smallest fish.

Thanks to this selection of the niHpnny and the direction of the light guide, as well as the shape of the plate 3, it ensures that the fish’s head fits snugly, when the fish heads pass forward, the light beam is obstructed and the photo relay works, and when the tail moves forward, the light beam or not at all , or partially obscured, and the photo relay does not work.

The working beam of light illuminating the cathode of the second photocell is normally directed to the slip plane directly behind the protrusion 5 of the plate 3 in such a way that it is obstructed as soon as the fish passes the protrusion 5, regardless of whether the fish moves with the head or tail forward.

The first photo relay controls the operation of the second photo relay. The second photo relay controls the operation of the executive relay. When triggered

The first photorelay breaks the relay circuit (apode) of the second photorelay and the last one cannot work, despite the light-beam barrier.

If, by the first photo relay, the object is blocked by the light beam of the second photo relay, then the second photo relay will work; the associated executive pe. te will also work. When the fish head moves, the first photorelay is triggered, but i: e the second actuator operates and the actuating relay controlled by it and the fish continue to slide forward unimpeded, i.e. it changes direction);:.

When the fish moves forward with the tail, the first relay does not work, but the second relay triggers and the executive relay n which is controlled by it is pushed by the plate of the executive relay and dropped onto the inverting plate, due to the reverse bias it changes the direction of movement and the head; and tastine is sent to the common outgoing stream.
