It comes out.

[Prior art]

What is important in the production of underground canned fish, especially cooked fish, is to minimize the error in the weight of the fish packed in the can. This is done by cutting out fish parts of uniform length with dimensions suitable for canning, by separating the head and tail. In terms of weight, this can be done by intuitively lumping fish of different sizes together. Pack pieces of fish that are at least approximately the same size together to improve the appearance of canned goods when opened. For this reason, and in order to adjust the desired content of the fish, by pre-sorting the fish according to dimensional divisions, it is possible to obtain canned contents of uniform length and with a small weight error. . When processing all fish of different sizes, the weight error can be kept approximately constant by changing at least one of the fillet length and packing form.

A device having the above-mentioned characteristics is disclosed in Spanish utility model application A, 250008 (6). In that device, fish placed in a trough of the desired mass are guided by a cutting mechanism. This cutting mechanism has two round knives. The cutters fit into slots between the gutter elements. A suction device-like evisceration device is provided downstream of the cutting @ structure. The suction device has two suction heads. Their suction heads are placed in the cutting plane of the round knife. The suction head enters into functional relationship with the decapitated surface of the local piece of fish.

If adjustments were to be made for fish of different dimensions, it would be very time consuming to adjust to the desired weight, and such adjustments could only be made when the device was stopped; That would be a disadvantage. Moreover, if one gutter is not occupied, it is unavoidable that the corresponding can, which is advanced in time with the gutter, can remain empty. This is particularly disadvantageous for machines that are coupled to each other - for example, a continuously operating unit that processes the contents of a can and a subsequent unit that fills the can and seals the can. .

[Summary of the Invention 1] Due to the need for rapid processing of fish, which is particularly important in tropical or subtropical regions to maintain freshness, the main object of the present invention is to process fillets of the butt of fish. To provide an entire device which can efficiently put fish into a can and maintain a predetermined packing pattern when the fish is packed into the can.

Another object of the present invention is to make it possible to easily adjust the length of local fillets without stopping operation. Yet another object of the invention is to improve the efficiency of downstream evisceration devices.

In a device of the type mentioned in the introduction to the description, on the base of each shelf element there is provided a base plate which forms the entire supporting surface for the fish and is adjustable in height, and in which the actuating element is arranged in the area of the feed V. 9, the actuating element is actuated in time with the forward movement of the inner element and enters into a functional relationship with the base plate 9, the blade of the cutting mechanism and the suction head centrally adjusting the spacing between them. configured to be adjustable by a mechanism;
A signal transmitter monitoring the filling of each inner element ensures that the can is delivered to the loading position by a loading machine which can be operated in time synchronization with the forward movement of the inner element;
This is accomplished in a device that processes fish and places it in cans.

The base plate is preferably constructed so that it can be elastically moved up and down by the force of the spring so that the fish is fixed in a given position while the fish is continuously moved during treatment 2. It's advantageous. Such fixing of the fish in a given position can be achieved by providing at least a very large belt covering these shelf elements in the bending area occupied by the inner side elements of the central conveyor section, which belt This can be accomplished in another preferred embodiment of the invention in which the central conveyor section is configured to be continuously rotationally driven to rotate synchronously with the central conveyor section or to rotate freely with the central conveyor section.

A pair of gripping elements surrounding the inner side element are provided in the region of the feed part in order to positively eject the butt contained in the trough from the trough. In this connection, the portions of a pair of gripping elements surrounding the entire inner gutter element may be formed into a roof-like shape that is symmetrical with respect to the lateral center of the shelf elements, or the portions of the gripping elements may be formed in a manner that is consistent with the movement of the inner side elements in time. in tune with
It would be convenient to configure it so that it is moved in the direction of releasing the grip.

In order to thus grasp the abdominal contents of the fish sucked into the suction opening and extract the contents from the abdominal cavity, the suction head is positioned within the level of the decapitation surface. Particularly advantageous cleaning effects can be achieved by means of effective means arranged behind the suction openings. This allows all internal organs protruding from the abdominal cavity to be safely extracted.

A particularly effective function is a rotating body that can be driven to rotate,
This is achieved by a means for grasping and extracting the internal organs, which comprises a clamping surface which is associated with the circumferential surface of the rotating body at a short distance from the circumferential surface. In that measure, the rotating body is preferably configured as a vane roller with different axial positions. Its axis can be approximately parallel or perpendicular to the conveying half plane.

A very simple solution can be achieved if the drive of the rotating body or vane roller is carried out by contacting the central conveyor section carrying the inner side elements. In this embodiment, it is advantageous if the suction heads are arranged offset from one another, and in particular it is advantageous if the suction heads are provided with shutters for closing the suction heads. The shutter can be configured to be actuated by the fish. With this configuration, vacuum can be concentrated on each suction head.

In accordance with a preferred embodiment of the loading mechanism, the can loading mechanism is controlled by a cam, the cam being driven in time synchronization with the forward motion of the gutter, to feed the can into the horizontal loading position. The loading mechanism is controlled and a locking mechanism is provided between the cam and the loading mechanism, which locking mechanism can be actuated by the positioning element and can be controlled in dependence on the switch signal of the signal transmitter.

To optimize the circuit arrangement, the signal transmitter can be located upstream of the feed section by the same number of troughs as the number of empty cans provided between the feed section and the feed section.

In order to completely prevent cans from reaching the feeder in an incorrect position, e.g. with the opening facing downwards, a monitoring device for controlling the position of the can path (C) in front of the feeder should be provided. I can do it.

It is arranged below the section 19. The can conveyor conveys cans or cans of canned goods to the central conveyor section 2 in such a way that for every internal gutter element 4 of the central conveyor section 2, cans 24 that remain stationary in time are associated with those gutter elements 4. Carry in sync with part 2. A cam disk 26 that moves in synchronization with the bending wheel T is fixed to the shaft 25 of the bending wheel T. The circumference 27 of the disc 26 is formed approximately in the shape of a chain tooth, corresponding to the pitch of the internal gutter element 4 . A rotor blade 28 for actuating the flap 22 is on the one hand in a functional relationship with this cam disk 26 and on the other hand with an actuating element 29 in the form of a lever with two arms. One end of the actuating element 29 is provided with a cam follower 31 and the other end is provided with a runner-like shoe. The cam follower is pressed against the cam disk 26 by a spring 30. The shoe can be rotated into the path of the tappet head 15 of the guide tappet 14 in the region of the feed section 18 . A gripping mechanism 33 is provided in the area of the feeding section 18 (FIG. 2)

The gripping element 34 is roof-shaped and forms an overlapping part 35 above the internal gutter element 4 . The gripping element 34 is connected to its shoe 32 in accordance with the actuating element 29 via an executable mechanism 36.

Refer now to FIG. The round blades 12 of the cutting machine 11 are guided so as to be movable relative to each other on a common shaft 37 and are driven by an electric motor 38. Both sides of the internal trough element 4, which is guided separately between the bending rings 7 and 8, abut the suction head 40 of the evisceration device. A slot-like suction opening 41 of the suction head is associated with the open front edge of the internal gutter element 4. The suction head 40 is adjustable in the longitudinal direction of the internal trough element 4 by means of a spindle 42 which is provided with a suitably configured left-right thread.

They face each other at a short distance from the 0 circumference. The shaft 45 of the vane roller 46 extends from the underside of the housing 47,
It contacts the drive wheel 49. The drive wheel 49 is in the form of a spring wheel or stub tooth, with corresponding teeth 50 on the underside of the internal gutter element 4.
Engage with each other.

A supply section (FIG. 5) is provided at the periphery of the can conveyor 230. In this supply section, the cans 24 are moved from the can path 52 to the can conveyor 23 in a timed manner.

This supply section has a loading mechanism 53. This loading mechanism 53
is pivotally connected to one end of a two-armed lever 54. A cam follower 55 is fixed to the other arm of the lever 54. This cam follower is under the force of spring 56! , is pressed against Sicum 5γ.

This cam is driven in synchronization with the gutter 6. The free end 58 of the lever arm, to which the cam follower 55 is fixed, extends above the cam follower. A locking mechanism is constituted by a receiver 60 actuatable by a positioning or setting element 59 arranged in the pivot path of its free end 58 . A signal transmitter 61 is associated with the positioning element 59. This signal transmitter is provided in the area of the central conveyor section 2.

The can path 52 can be formed by a belt conveyor 62. Two proximity switches 63 are arranged below the lower extension of the belt conveyor 62 and spaced apart by the same distance as the cans 24 so as to be exposed to the bottom of the cans 24.

Next, the operation of this device will be explained.

The fish fed into the gutter 6 is first guided to the cutting mechanism 11. When feeding fish into the trough, the cutting mechanism 11 cuts the head and tail of the fish located in the internal trough element 4 so as to feed three or four fish preferably in mutually alternating positions. Separate the local parts of the fish. The head and the tail part include an outer conveyor part 1 holding an outer tank element 5,
3 is immediately bent and guided to the rainbow waste container, while the local fillet is guided to the evisceration device. The evisceration is carried out by the action of low pressure during the passage of the severed side through the head of the local fillet. Due to its low pressure, the abdominal cavity of 6 fish is sucked by the suction head 40
is charged by the cut surface of the head pressed against the suction opening 41 of the head. The parts of the internal organs that are fixed within the abdominal cavity by ligaments are connected to the housing 4 of each suction head 40.
It is grasped by the pry-like gripping action of the vane roller 46 located within the cutter 7, and is safely extracted from the abdominal cavity by the action of the rotation of the vane roller 46 and the forward movement of the local fillet 64. The weight of the shredded fish parts placed in the cans thus obtained is influenced by the rotation of the left-right threaded spindle 420 during operation of the device. By turning the left-right spindle 42, the distance between the suction heads 40 is changed relative to the distance between the round knives, so that the length of the local fillet can be changed.

In order to save energy and reduce noise, the suction opening 41 of each suction head 40 can be provided with a cover plate configured as a raised L.

The local fillet 64 is directed downstream of the central conveyor section 2 into the area of the bending ring 7 . While being carried, the local fillet 64 moves under the flap 22. This flap 2
2 is rhythmically raised and lowered in synchronization with the inner tank element 4, and the pace plate 13 is moved under the action of the force of the springs 16.
Due to this movement, the packed mass, ie the local fillet packed into each gutter element, is equalized to a uniform level. The measured mass is kept at that level by the subsequent cover plate 20. When the mass to be stuffed reaches the feed section 18, it is moved against the part 35 of the holding and gripping machine 33 surrounding the inner tank element 4 and the spring 16, which can be biased, against the force of gravity. is retained. This action is cascaded until the actuating thread 29 is actuated by the cam disk 26 and forces the tappet head 15 of the guide tappet 14 down with its shoe 32. The actuating element 29 is connected to the gripping mechanism 33 via an expansion mechanism 36, so that the gripping elements 34 are gradually expanded and the stuffing mass is released. In this operation, the rate of descent of the actuating element 29 is synchronized so that the pace plate 5 safely contacts the filling mass.

In place of the cover guide 20, a large belt cover can be used to cover the opening of the inner tank element 4; this also avoids stress on the local fillet 64 of the fish due to friction.

In this way, maintaining the filling pattern in the inner tank element 4, the local fillets 64 reach the can 24 held in the feeder 18 in synchronization with the rhythm of the movement of the gutter element 4. In this device, cans are fed by a can conveyor 23 fed with =24 from a can path 54. The cans 24 are supplied by the can conveyor 23 by a mechanism provided in the supply section 51. The operation of this mechanism is monitored by a signal transmitter 61. The signal transmitter 61 is the can 24
into the path of the can conveyor 23. Signal transmitter 61
When registering an empty trough, no actuation signal of the positioning element 59 occurs, so that the loading mechanism 53 remains strongly held in the retracted position by the receiver 60. When the trough element 4 filled with fish passes close to the signal transmitter 61 , the positioning element 59 is placed in the raised position of the cam 57 such that the free end 58 of the lever 54 is released by retraction of the receiver 60 . At the same time that the part facing the cam follower 55 receives an actuation signal. This means that the force of spring 56, c
, b The cam follower 55 can follow the cam 5γ, and the loading mechanism 53
The can path 52 is provided with a belt conveyor 62 for carrying the cans 24 at least slightly upstream of the feeding section 51. The cans reach the conveyor by the action of gravity. can.

In the belt conveyor, each can standing upright for loading can be gripped by a lateral leaf spring, thereby preventing impact pressure from subsequent cans. During the loading process, the leaf spring is displaced by the can to be loaded and bounced back behind the can into the path of the next can so that it can hold the next can.

The signal transmitter can be configured as a contactless sensor, for example an optical sensor, or a mechanically operated sensor.

Monitoring of the position of the can 24 in the can path 52 can be carried out by two proximity switches 63, which are separated by the same distance as the pinch of the can and connected in series with each other, at the bottom of the can. It can be operated well. A change in the signal caused by a mispositioned can can be used to activate a removal mechanism that removes the can.

Proximity switches 63 can be connected so that a change in the signal caused by the lack of can supply can be used by both proximity switches 63 as a signal for the lack of can supply.
