Description

[Detailed Description of the Invention] This invention relates to an automatic fish cooking machine, specifically, to a fish cutting device in an automatic fish cooking machine that automatically processes fish at high speed.

The head and tail of the fish to be canned are removed, and then the meat is cut into several pieces to fit the size of the can. A device for cutting this fish body is a fish body cutting device.

Conventionally, in automatic fish cooking machines, cutting of fish bodies has been carried out while being conveyed by a conveyor. The conveyor is provided with a large number of holding parts that hold fish bodies with tails in a direction perpendicular to the direction of movement of the conveyor. Near the rotating trajectory of the conveyor, there is a fish head alignment mechanism for aligning the fish body, a head removal mechanism for removing the head of the fish body, and a head removal mechanism for pulling out the internal organs from the decapitated fish body. A visceral removal mechanism, a tail cutting mechanism for cutting off the tail of a fish, and a fish cutting device for cutting the fish into a plurality of pieces of fish meat are each disposed. This fish body cutting device is comprised of a cutter that enters into the rotating locus of the conveyor and cuts the fish body, and a cutter entry groove that is formed in the holding portion parallel to the rotating direction of the conveyor. Further, a plurality of cutters are arranged in a row according to the required size of fish meat. In other words, the cutter entry grooves formed in the holding portion are also provided in accordance with the number of cutters provided. The cutter is placed on the holding section, and cuts the fish body from which the head, internal organs, and tail have been removed, leaving only the edible parts, into a plurality of pieces of fish meat.

By the way, the structure required for cutting a fish body to a certain length is that the fish body does not move randomly when cutting the fish body with a cutter, that the fish body does not move randomly due to the vibration of the conveyor, and that it is possible to cut the fish body into various sizes. That's true.

As mentioned above, the conventional device has a problem in that the cutting dimensions of the fish cannot be easily changed because the cutter entry groove into which the cutter enters is provided parallel to the traveling direction of the conveyor. The cutting dimensions of the fish body vary depending on the type of can. Furthermore, even if the fish is of the same species, there are differences in the size of the fish body itself, and there are fish bodies that are large enough to be cut into only two pieces of fish meat, and fish bodies that are large enough to be cut into three fish pieces. If the cutter mechanism cannot easily change the cutting dimensions, even if the fish body is large enough to be cut into three parts, it will be cut into two parts, resulting in a poor yield of fish meat. Further, the cut surface of the fish body must be perpendicular to the longitudinal direction of the fish body. In other words, it is necessary to prevent the fish body from moving erratically during cutting. In order to prevent the fish placed on the holding part of the conveyor from moving unintentionally, it is sufficient to hold the fish so that it does not move at the cutting position, but since there are many holding parts arranged along the entire length of the conveyor. , the disadvantage is that the structure is complicated. Furthermore, in the step of cutting off the head, internal organs, and tail of the fish, it is necessary to move the fish in the longitudinal direction of the fish, that is, in a direction perpendicular to the moving direction of the conveyor. Therefore, the structure of the holding part must not obstruct the necessary movement of the fish body, but in conventional fish body cutting devices, it is necessary to have a structure that prevents the fish body from moving inadvertently and does not hinder the necessary movement of the fish body. Adopting this has the disadvantage of making the structure even more complex.

The present invention has been developed to solve the various problems mentioned above, and has a structure that can cope with the cutting of fish bodies of various sizes, does not impede the movement necessary for processing the fish body, and can prevent the movement of the fish body inadvertently. To provide a fish body cutting device for an automatic fish cooking machine capable of easily and stably cutting fish bodies.

The present invention is characterized in that the process of cutting the fish body, which contains only the edible part, is carried out at a position separated from the fish conveyance path by the conveyor. In this invention, a star-shaped rotating body is placed at the end of the conveyor that conveys the fish body, which has only edible parts, and the fish body is held in the fish body holding groove formed in this star-shaped rotating body so that it does not move accidentally. The structure is such that it is cut into a plurality of pieces at the same time.

Hereinafter, the present invention will be explained in detail with reference to an illustrated embodiment.

In FIG. 1, reference numeral 1 indicates a conveyor. The conveyor 1 is wound around a driving wheel 2 and a driven wheel 3. The drive wheel 2 and the driven wheel 3 are rotatably supported by a support member (not shown). of the shaft 4 of the drive wheel 2;
Two sprockets 6 and 7 are fixed to one end 5, and a sprocket 9 is fixed to the other end 8. A chain 13 is wound around the sprocket 9 and a sprocket 12 fixed to an output shaft 11 of a drive motor 10. A large number of trays 14 are arranged and fixed on the outer peripheral surface of the conveyor 1 as a holding section for holding fish bodies. This tray 14
The fish body F is placed in a direction perpendicular to the traveling direction a of the conveyor 1, and has a length sufficient to place the longest fish body to be processed and a shallow U-shaped cross section. .

Near the upper part of the conveyor 1, there is a fish head arrangement mechanism 15, a head removal mechanism 16, and a visceral removal mechanism 1.
7. A tail section cutting mechanism 18 and a fish body positioning mechanism 19 are respectively arranged along the traveling direction of the conveyor.

On one side of the conveyor 1, an auxiliary conveyor 20 for conveying the heads of fish bodies is provided in parallel with the conveyor 1. The auxiliary conveyor 20 has a driven wheel 3
It is wound around a wheel 21 disposed near the head removal mechanism 16 and a wheel 22 disposed between the head removal mechanism 16 and the viscera removal mechanism 17 . wheel 2
A sprocket 24 is fixed to the shaft 23 of No. 2, and this sprocket 24 and the sprocket 6
A chain 25 is wound between.
The auxiliary conveyor 20 is provided with auxiliary trays 26 at the same pitch as the trays 14. Drive motor 1
When 0 rotates, conveyor 1 and auxiliary conveyor 2
0 is rotated in the direction of arrow a at the same speed.

The fish head alignment mechanism 15 is a mechanism that automatically sets the position at which the fish head is cut according to the size of the fish. This mechanism 15 is known from Japanese Utility Model Publication No. 57-45826.

The head cutting mechanism 16 has a cutter 27 that cuts off the head of the fish body, and this cutter 27 has a cutter 27 that cuts the head of the fish.
It has entered the gap between the conveyor 1 and the auxiliary conveyor 20. The viscera removal mechanism 17 includes a guide plate 28 that abuts the cut surface of the decapitated fish body, and a suction tube 30 that faces an opening 29 formed in this plate and is connected to a suction device (not shown). The entrails of the fish are removed using vacuum suction. The tail removal mechanism 18 includes a rotating body 31 that moves the fish body Fa from which the internal organs have been removed to the other side edge of the conveyor 1;
Tray 1 that regulates the tail of the fish being moved
4 to form a wedge-shaped space, and a cutter 33 for cutting the tail. This cutter 33 and the cutter 27 have pulleys 36 and 37 fixed to shafts 34 and 35, respectively, connected to each other by a belt 38, and are rotated in the direction of the arrow by a drive source (not shown). The fish body positioning device 19 includes a rotary body 39 that moves the fish body, which was displaced to the other side edge of the conveyor 1 during the tail removal, to the one side edge of the conveyor again, and an edible fish body that is moved by the rotating body 39. Fish body with only part Fb
It consists of an abutting plate 40 that abuts against. In addition, in FIG. 1, the conveyor 1 and the tray 14
are partially omitted to avoid complicating the figure.

A guide plate 41 is arranged around the portion of the conveyor 1 that is wrapped around the drive wheel 2 and is curved along this portion. This guide board 41
cooperates with the tray 14 to clamp and transport the edible portion only and the fish body Fb to the end position of the winding portion of the conveyor 1. In other words, in the moving direction of the conveyor 1, the terminal edge of the guide plate 41 can be said to be the terminal end of the fish body conveyance by the conveyor.

A fish body cutting device 4 is located below this fish body conveyance terminal part.
2 are arranged. This device 42 consists of a star-shaped rotating body 43, a fish guide member 44, a cutter mechanism 45, and a drive means 46.

In FIGS. 1 to 4, the star-shaped rotating body 43
is made of synthetic resin, for example, and flanges 48, 48 are fixed to both ends of the rotation center hole 47. A support shaft 49 is inserted through the rotation center hole 47, and each flange 48 is fixed to the support shaft. The support shaft 49 is connected to the drive wheel 2
It is rotatably supported by a support member (not shown) in parallel with the axis of the
0 is fixed. Between the sprocket 50 and the sprocket 7, a chain 51 is wound in an intersecting manner. A fish body holding groove 52 is formed on the circumferential surface of the star-shaped rotating body 43 along its axis. The bottom portion 52a of this fish body holding groove 52 is inclined in the longitudinal direction. That is, the fish body holding groove 52 gradually becomes deeper from the right end to the left end in FIG. Also, this groove 52
The width gradually increases from the right end to the left end. In addition, the fish body holding groove 52 is shown in FIGS. 3 and 4.
As you can clearly see from the figure, the rotation axis (support shaft 49)
It is formed so as to exhibit a cross-sectional shape that gradually becomes narrower toward the end. That is, the groove is tapered in the depth direction. Such a fish body holding groove 52
The shape corresponds approximately to the shape of a fish body.
In other words, the fish body, which has only edible parts, has a shape where the head is separated and the fish body tapers toward the tail. The fish body holding groove 52 has a length sufficient to hold the maximum length of the fish body with only the edible part.

A plurality of circumferential grooves 53 are formed in the star-shaped rotary body 43 in its circumferential direction so as to be orthogonal to the fish body holding grooves 52. Note that FIG. 1 shows an example in which three circumferential grooves 53 are formed, and FIG. 2 shows an example in which six circumferential grooves 53 are formed, but this difference will be described later. Each circumferential groove 5
3 is deeper than the deepest part of the fish body holding groove 52. A cutter enters this circumferential groove 53.

The cutter mechanism 45 includes a disc-shaped cutter 54 that enters the circumferential groove 53, a shaft 55 that supports the cutter 54, and a drive source (not shown) that rotationally drives this shaft. cutter 54
The cutting edge is located further toward the axis than the bottom 52a of the fish body holding groove 52. Note that three cutters 54 are shown in FIG. 1 and two cutters 54 are shown in FIG. 2, but this point will be described later.

The circumferential groove 53 and the cutter 54 entering it
The number of fish and the pitch at which they are arranged are determined by various factors such as the length of the fish body based on the fish species and the number of pieces of fish meat to be cut into the fish body. In Figure 1,
Since the three cutters 54 are respectively inserted into the three circumferential grooves 53, the maximum length of the fish is cut into four pieces of fish meat. Incidentally, the length of the fish body differs depending on the type of fish or even for the same type of fish, and the desired length of the fish meat varies depending on the type of canned food. Therefore, if the number of cutters is fixed, the types of fish and the length of fish meat that can be processed are fixed. Therefore, as shown in FIG. 2, a large number of circumferential grooves are formed, and a cutter 54 is provided so as to be movable in the axial direction with respect to a shaft 55. Then, by selecting the number of cutters according to the fish species and desired length of fish meat, entering the cutters into the selected circumferential grooves, and fixing them to the shaft 55, it is possible to cut multiple fish species and cut them. You will be able to handle the length. In other words, fish meat can be cut with the highest yield.

The fish guide member 44 surrounds a part of the outer periphery of the star-shaped rotating body 43. One side edge of the fish body guide member 44 is connected to the upper end of the star-shaped rotating body 43 and the fish body receiving portion 5.
6, and the other side edge 57 forms a fish body discharge part 58 which is spaced apart from the rotating body and inclined. A slit 59 into which a cutter 54 enters is formed in the fish guide member 44 . Hereinafter, the position where the star-shaped rotating body 43 and the cutter 54 intersect is a fish body cutting position 60.
(See Figure 3). This fish body guide member 44 cooperates with the fish body holding groove 52 to hold and guide the fish body Fb, which has only the edible part. Moreover, both side parts 61 and 62 of this member 44 are bent,
As shown in Figure 1 and Figure 2, one each,
It is close to both end faces of the star-shaped rotating body 43. Because the fish body holding groove 52 is inclined, the groove 52
The fish that are fed into this area tend to move towards the left end in Figure 2. Therefore, when this is brought into contact with the side part 62 of the guide member, the side part 62 can be used as a reference surface for cutting the fish body. It goes without saying that the side portion 62 serving as the reference plane may be provided separately from the fish guide member 44. In addition, the fish body guide member 4
4 so as to be movable toward and away from the star-shaped rotating body 43, it is advantageous that, together with the tapered cross-sectional shape of the fish body holding groove 52, it is possible to handle fish body holding that suppresses the movement of fish bodies with different body circumferences. be.

In the illustrated embodiment, the drive means 46 is driven by a sprocket 7 that is substantially integral with the drive wheel 2 that drives the conveyor 1. The number of teeth of each sprocket 7, 50 is set so that the moving speed of the star-shaped rotating body 43 is synchronized with the moving speed of the conveyor 1. In other words, the relative moving speeds of the tray 14 and the fish body holding groove 52 are equal. Further, the driving means 46 rotationally drives the star-shaped rotating body 43 in the direction of the illustrated arrow. That is, the fish body Fb released from the tray 14 and the guide plate 41 is
The fish falls in a parabolic curve, and the star-shaped rotating body 43 rotates in the same direction as the moving direction of the fish. It goes without saying that the star-shaped rotating body 43 may be driven by a drive source different from the drive source of the conveyor 1.

The operation of the present invention constructed as above will be explained based on FIG. 1.

First, the number and position of the cutters 54 are set according to the required length and number of pieces of meat. When the power is turned on, conveyor 1 and auxiliary conveyor 20
and the star-shaped rotating body 43 rotate in the directions indicated by the arrows, and the cutters and the rotating bodies also rotate in the directions indicated by the arrows. Furthermore, the viscera removal mechanism 17 also starts operating. At the fish placement position 63, individual fish are placed on each tray 14 manually or by an automatic fish alignment machine. At this time,
The fish F are arranged so that the heads are on the front side in the figure, and the heads are positioned on the auxiliary tray 26. When the fish F reaches the fish head alignment mechanism 15 by the rotating conveyor 1, the body thickness of the fish is measured, and the position of the fish is adjusted in the direction of movement of the conveyor 1 according to the measured value. be moved in the orthogonal direction. This determines the cutting site of the head. The arranged fish body is the head removal mechanism 16
When it reaches the part, the cutter 27 cuts off its head. The severed head is placed in the auxiliary tray 2.
6 and is ejected from the tray as it rotates downwardly along wheels 22. The fish body from which the head has been removed is moved so that its cut surface comes into contact with or very close to the guide plate 28 . When the cut surface of the fish body faces the opening 29, the internal organs are suctioned and removed by the suction tube 30. The fish body Fa from which internal organs have been removed is rotated by the rotating body 31.
The tray 14 is moved to the other side and its tail is cut off by the cutter 33. After the tail cutting process has been completed, the fish body Fb, which has only an edible part, is moved again to one side of the tray 14 by the rotating body 39, and the cut surface of the head is brought into contact with the abutting plate 40. Transported while moving. The abutting against this abutting plate 40 is a preliminary step for cutting into a predetermined size in the next cutting step.

In this way, when the conveyor 1 rotates along the drive wheel 2, the fish body Fb that is transported with the head cut surface positioned on the cutting reference plane is placed on the tray 14.
and a guide plate 41. After passing the lower edge of the guide plate 41, the fish body Fb is released from the tray 14 and falls. At this time, the fish body Fb falls while drawing a parabolic curve, but this fish body
The fish body holding groove 52 of the star-shaped rotating body 43 receives it.
Even if the fish body Fb that falls into the fish body holding groove 52 is separated from the cutting reference plane regulated by the abutting plate 40, this fish body will continue along the slope of the fish body holding groove 52. It slides toward the side 62 (see Figure 2) and automatically returns to its reference position. When the fish holding groove 52 that has received the fish rotates to face the fish guide member 44, the fish is held between the groove and the guide member 44 and moves as the star-shaped rotating body 43 rotates. Then, when this fish body Fb moves to the fish body cutting position 60 (see Fig. 3),
This fish body is cut into four pieces of fish meat Fc by cutters 54 in the illustrated example. The cut fish meat Fc reaches the fish body discharge section 58 and is released from the star-shaped rotating body. This fish meat Fc is transported to the next step by means not shown.

As described above, according to the fish body cutting device of the present invention, the fish body is shredded at a position separate from the step of processing the fish body into only edible parts, so that the position of the fish body during cutting is stable. Therefore, there is no variation in the length of the cut pieces of meat Fc. Also,
By holding the fish body with a star-shaped rotary body and cutting it, it is possible to construct a device that suppresses the movement of the fish body during cutting very easily. When changing the cut length of a fish body, it is a simple task of changing the position of the cutter 54, so it is possible to process many types of fish or fish with different body lengths even if they are the same species. By setting the rotating direction of the star-shaped rotating body in the same direction as the parabolic curve drawn by the fish body Fb released from the tray 14, the falling fish can be smoothly received into the fish body holding groove 52. The fish body no longer moves erratically when giving and receiving.
