2. Description of the Related Art Opening and opening a eel to cut live eel for broiling requires a high degree of skill, and it is desired to mechanize this operation.

[0003] Conventionally, as an eel back opening and belly opening apparatus, there is an apparatus disclosed in Japanese Patent Publication No. 57-1975. In this apparatus, as shown in FIGS. 12A and 12B, a pair of left and right long holding belts 94, 94 are arranged in the length direction of the central portion of the machine frame 91, and the center of the facing surfaces of these holding belts is provided at the center. An insertion hopper 96, a horizontal support member 97, a cutter 98, and a pair of left and right V-shaped cutters 99, 99 are sequentially arranged from the transport start end side to the end side.

In such a device, when eel put into a suspended state by electric shock or cooling at 10 ° C. or less is inserted into the inclined hopper 96 with its back or abdomen directed downward, the eel is pinched when it reaches the horizontal support member 97. Belt 9
4 and 94 and the horizontal support member 9
While being kept horizontal by 7, the cutter 98 cuts the entire length from the center of the lower part of the eel to the center of the lower end of the spine.

[0005] Further, the eel is transported toward the transporting end, and V-shaped cutters 99, 99 apply V-shaped cutters from above the spine.
The spine is cut off along the inside of the lower two-sided flesh that has been expanded in a letter shape.

[0006] The spine of the eel thus cut off falls down and is housed in a storage case (not shown), and the cut eel is discharged from the trailing end of the holding belt to a chute (not shown).

[0007]

The above-described apparatus is large in size, and has a problem that a large mounting space is required because the holding belts 94 and 94 are linearly developed on a plane.

In addition, such a large-sized device is expensive and has a high running cost. In particular, it is costly to introduce such a device in a retail store or a mass retail store that sells eel to consumers. Was not worth it.

Further, in order to move the eel in a straight line while being pinched by the pinching belts 94, 94, the eel must be strongly pinched in order to make an accurate incision. However, there is also a problem that the meat quality is inevitably reduced due to the compression.

Further, depending on the size and shape of the eel, adjustment of the spacing between the sandwiching belts 94, 94 and the like is required, and there is a problem that the operation becomes complicated.

Therefore, the present applicant has previously invented an apparatus capable of solving the above problem (Japanese Patent Application No. Hei 6-327183).
This device is an eel incision device that incises a live eel for broiling, separates its bones and internal organs, and discharges it as a back-opened eel with a head.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An apparatus according to a preferred embodiment of the present invention will be described with reference to FIGS.

This apparatus is an eel incision apparatus for incising a live eel for broiling, separating the spine and the internal part of the eel, and discharging the eel as a headed eel body with the back open.

As shown in FIGS. 1, 2 (a) and 2 (b), the present apparatus removes live eel through a supply pipe mechanism 20 for eel onto a part of the upper peripheral surface of the rotary drum 30. The eel is supplied in the tangential direction, and the eel's head and body are successively clamped by a large number of clamping blocks attached to the rotating drum, and the eel is held in an arc shape along the outer circumference of the rotating drum while the rotating drum rotates. While the eel is being transported in the circumferential direction, the eel body cutting cutters 100a and 100b arranged on the peripheral edge of the rotating drum sandwich the eel's spine, cut into the torso from the back and make an incision. Insert the cutters 300a and 300b to separate the spine and the internal organs, and when the eel moves below the rotating drum, release the jaws of the jaw block in order to discharge the eel body with the head open in the back state. From shoot 5 In which it was to be out.

More specifically, the present apparatus comprises a gantry 1, a fixed frame 2 attached to the gantry 1, a main shaft 31 provided between the fixed frames 2, and a rotating drum 30 mounted on the main shaft 31. The drive motor 3 and the control panel 4 are provided on the fixed frame.

As shown in FIGS. 1 (a), 1 (b) and 2, a large number of clamping blocks 60 are disposed on the outer periphery of the rotary drum 30 and a plurality of cam plates 110a, 110b, 310 and 39 are mounted concentrically with the main shaft 31, and these cam plates are used to cut the torso incisors 100a and 100b, the bone-incorporated separation cutters 300a and 300b,
Oscillate according to the rotation angle of the rotating drum 30.

The rotating drum 30 has a belt wheel 3
A belt 35 for transmitting the rotational force from the drive motor 3 is wound around this belt wheel 34. When the drive motor 3 is rotated by operating the control panel 4, the belt 35 The rotating drum 30 is configured to rotate via the.

First, a supply mechanism for supplying raw eel in a tangential direction above the rotating drum 30 will be described.
As shown in FIGS. 3A to 3C, the supply mechanism includes a supply chute 10 and a supply pipe mechanism 20, and the end of the supply chute 10 is located at the start end of the supply pipe 21 and the end of the supply pipe 21 rotates. It is provided so as to be located at the upper end of the drum 30.

The supply chute 10 supplies raw eel to a supply pipe 21.
And gradually narrows as it approaches the connection end with the supply pipe 21 and is inclined downward. The eel placed in the supply chute 10 enters the narrow supply pipe 21 from its tip and gradually becomes linear.

The supply pipe mechanism 20 is composed of two supply pipes 21, 21 divided in the horizontal direction, and an opening / closing mechanism for opening and closing the supply pipes 21, 21. Eel enters between the two supply pipes 21, 21. Then, when the eel moves forward to a predetermined position, the supply pipe is closed and the eel is held in a straight line. When the supply pipe is closed, vertically facing slits 21a and 21b are formed in the longitudinal direction, and the upper fin and the lower abdomen of the eel are inserted between the upper and lower slits, so that the upper and lower sides of the eel can be inserted. I keep my posture right.

As shown in FIGS. 3A and 3B, the opening and closing mechanism is supported by a swing block 22 which is rotatably supported on a fixed frame 2 erected on a gantry 1 in a vertical plane. Board 23
Is attached. The support plate 23 is provided with two divided supply pipes 21, 21 and inverted L-shaped bases 21 c, 2.
Horizontal T-shaped swing levers 24, 24 supported via
The lower end of each swing lever is pivotally attached to the upper end of a sliding link 24a, and the lower end of the sliding link 24a extends along a guide slot 23a formed in the support plate 23. The guide pin 25 and the shaft 26 that supports the swing levers 24, 24 are connected via a tension spring 27 so that the supply pipes 21, 21 are always closed. It is energizing.

One end of a wire 28 is attached to an end of the guide pin 25 to which the tension spring 27 is attached. The other end of the wire 28 is shown in FIG.
In conjunction with the operation of the perforation lever 40 in (b), the supply pipes 21 are closed by operating the perforation lever 40.

[0042] Then, in a state where raw eel is not supplied,
The wire 28 is pulled to the other end, the tension spring 27 is extended, and the guide pin 25 is guided by the guide elongated hole 23a to move downward, and the swing levers 24, 24 are rotated to supply the supply pipes 21, 21. Is open.

On the other hand, when the raw eel is supplied and the wire 28 is extended by operating the perforated lever described later, the tension spring 2
7 contracts, the guide pin 25 moves upward, and the supply pipe 21 is elastically closed. In this state, the variation in thickness of the raw eel can be absorbed by the tension spring 27 and the raw eel can be held so that it cannot move by itself.

As shown in FIG. 4 (a), a plurality of rubber bands 29, 29, 29 are arranged on the outer periphery of the supply pipe 21 to assist the supply pipe in elastically closing and to provide raw eel. Absorption and holding of variations in thickness can be performed more reliably. In this case, it is desirable that a cushion material such as rubber is adhered to the inner surface of the supply pipe so that the body of the raw eel is not damaged by the supply pipe being too closed. In this state, as shown in the vertical cross-sectional view of FIG. 4B, the dorsal fin projects from the upper slit 21a and the lower slit 2
1b, the lower end of the abdomen protrudes slightly, and the head and neck protrude from the front end of the supply pipe 21.

When the supply pipe 21 is closed, the foremost block of the plurality of holding blocks 60 disposed on the peripheral portion of the rotary drum is positioned on the extension of the supply pipe and stands by. . At the front end of this state-of-the-art clamping block, there is provided a head stopper 41 extending in a direction traversing the periphery of the rotating drum. Raw eel enters the supply pipe and advances, and the head of the eel is moved to the head stopper. The supply pipe is closed as described above.

After the supply pipe is closed in this manner, a needle is inserted into the head of the raw eel, so-called perforation, in order to fix the head of the raw eel to the cutting-edge holding block. For this reason, a piercing needle protrudes inward from the inner surface of the state-of-the-art holding block, and the holding block can be freely opened and closed in the radial direction of the body of the eel.

Here, the holding block 60 and its opening / closing mechanism will be described with reference to FIG. The holding block 60 has a pair of L-shaped cross-sections 60a, 60a disposed on the periphery of the drum 30 so as to face each other, and the lower surfaces of these holding pieces are attached along the outer peripheral side of the rotary drum. It is slidably mounted on the receiving plate 32. An upper surface of the receiving plate 32 is formed with a concave portion 32a having an arc-shaped cross section along the longitudinal direction thereof, and the concave portion is for storing and stably holding the lower trunk of the eel.

Mounting plates 45, 45 are attached to the outer surfaces of the holding pieces 60a, 60a, respectively.
5a and 45a, which are rotatably attached to upper free ends of holding levers 44 and 44 having a U-shaped curved portion. The lower arm portion of the holding lever is pivotally connected to a flange projecting outward from the rotary drum 30 by shafts 43, 43, and the central portion of the holding lever is urged by a tension spring 42 in a direction approaching each other. Gear teeth 44a are formed at the free ends of the lower arms of the holding levers 44, 44, and the gear teeth 44a, 44a mesh with each other. A driven roller 47 is rotatably attached to the lower outer side of one of the holding levers 44, that is, the holding lever 44 on the side close to the fixed frame 2.
7 is a fixed cam 3 attached to the side of the fixed frame 2
8 rolls on the cam surface. In the position where the cam surface of the fixed cam 38 protrudes toward the rotary drum, as shown in FIG. 5A, the lower portion of the one holding lever 44 is pushed toward the rotary drum 30 so that the shaft 43 is centered. The upper part swings toward the fixed frame 2 side. On the other hand, the other holding lever 44 has the gear teeth 44a, 44
Due to the engagement of a, the upper portion swings toward the rotary drum side against the tension spring 42. Thereby, both holding pieces 60a,
60a move in a direction to isolate each other. On the other hand, when the cam surface of the fixed cam 38 is recessed toward the fixed frame 2, the holding levers 44, 44 are rotated in the direction approaching each other by the tension spring, and the upper end The holding pieces 60a, 60a move so as to hold the eel. In the present embodiment, thirteen holding blocks 60 having the same configuration as those described above are provided close to each other and over substantially half the circumference of the rotary drum. The cam surface of the fixed cam 38 for opening and closing the holding block is closed when each of the holding blocks 60 passes through the distal end of the supply pipe 21, and expands when reaching above a discharge chute 5 described later. It is formed to open. In addition, the above-mentioned holding piece 6
The receiving plate 32 located on the lower surface of the rotary drums 0a and 60a extends continuously in the circumferential direction of the rotary drum along the direction in which the holding blocks 60 are provided.

Of the above-mentioned holding blocks 60, piercing needles 46, 46 are provided on the lower inner surfaces of the opposing holding pieces 60a, 60a of the leading-end holding block, and these holding pieces are used to hold other holding pieces following the back. It is configured to move in the opening and closing direction larger than the holding piece of the block, so that when the eel enters the holding block, the puncture needle does not hinder the entry.

As described above, in order to enable a large opening and closing operation of the state-of-the-art clamping block, a sliding rod 48 is provided through the fixed frame 2 and the fixed cam 38 as shown in FIG. When the sliding rod 48 is in the projecting position, it projects inwardly from the cam surface of the fixed cam 38 and presses the driven roller 47 at the lower end of the holding lever inward. Opening is greater than with the cam surface. The outer end of the sliding rod 48 is shown in FIG.
As shown in (b), one end of a U-shaped lever 49 pivotally attached to a flange 2a fixed to the fixed frame 2 is resiliently pressed by the compression force of a compression spring 49a, and the other end of the lever connects a link 49b. It is pivotally connected to the base of the perforating lever 40 through the intermediary. The tip of the perforation lever 40 is attached to a shaft 52c of a bearing block attached to the fixed frame 2 so as to rotate together with the shaft 52c.

With the above structure, when the perforating lever 40 is turned in the direction of the arrow in FIG. 5B, the dog-shaped lever 49 is turned counterclockwise via the link 49b, and is slid accordingly. The rod 48 moves outward from the fixed frame 2 by the action of the spring 49a, and the inner end of the sliding rod moves so as to be flush with the cam surface of the fixed cam 38. Since the driven roller 47 is in pressure contact with the inner end of the sliding rod, the driven roller 47 moves on the same plane as the cam surface with the movement of the sliding rod 48, and the driven roller 47 is attached. The holding lever 44 and the other holding lever opposing the holding lever 44 mutually rotate in the direction of holding the eel by the action of the spring 42. At this time, a piercing needle attached to the state-of-the-art clamping block pierces the eel's head from both sides, perforates the eel's head, and fixes it to the state-of-the-art clamping block.

By perforating the head of the eel body as described above, the raw eel can be prevented from moving on its own, and the eel body placed on the receiving plate 32 can be rotated by the rotating drum 30.
When performing the incision separation work to be described later by rotating the incision separation work described later, a stable incision separation work can be performed without causing a position shift.

Further, in the above embodiment of the present invention, the neck is cut after the perforation of the head of the eel. FIGS. 2 and 5 show a mechanism for cutting the neck.
As shown in (a) and (b), the fixed frame 2
A cutter 50 for cutting the neck is provided above the cutting block, and the cutter is rotatably provided through a gap between the leading-edge clamping block 60 and the subsequent second clamping block. That is, the cutter 50 is fixed to one end of a shaft 51b rotatably supported by a bracket 51a protruding above the rotary drum 30 from the fixed frame 2, and this shaft 51b
A pinion 51c is attached to the other end of the fixed frame 2 so as to rotate integrally with the pinion 51c.

The other end of b is a shaft 52c that rotates together with the perforation lever 40.
It is stuck to. One end of the wire 28 is fixed to the center of the link 52b.

With the above configuration, when the perforating lever 40 is rotated as shown in FIG. 5B, the rack 52 slides along the guide frame 52a in the direction of the arrow via the link 52b and meshes with the rack. The pinion 51c rotates about half a turn, and the cutter 50 that rotates integrally with the pinion is shown in FIG.
Then, the neck of the raw eel located between the earliest clamping block and the subsequent second clamping block is cut off as shown by the dotted line in FIG. At this time, as is apparent from FIG.
A concave portion 32a is formed on the receiving plate 32, and a part of the neck portion of the eel is located here, so that the cutter does not cut at least this portion, so the lower end portion of the eel is left. Beheaded in state. In this way, the cutting and perforation of the neck of the eel are performed by the rotation of one perforation lever 40.

One end of the wire 28 connected to the supply pipe 21 is attached to the link 52b which swings by the rotation of the perforation lever 40, and the link 52b swings by the rotation of the perforation lever 40 in the direction of the arrow. When moved, the wire 28 is extended, and the supply pipes 21, 21 are closed via the swing levers 24, 24a as described above.

In the above-described embodiment, an example in which the perforating lever is manually rotated is shown. However, the raw eel enters the supply pipe and advances, and the head of the eel hits the head stopper 41. It is also possible to detect the contact and automatically rotate the perforation lever as shown by the arrow in the figure.

The eel perforated and cut at the neck as described above is forcibly pulled out of the supply pipe 21 with the rotation of the rotary drum 30, and sequentially enters into the second and subsequent holding blocks, whereby the torso is formed. While rotating while being sequentially held, it reaches the position facing the cutter for cutting the eel trunk.
