Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fish processing device, and more particularly to a device for splitting a fish into pieces or cutting the fish into three pieces.

BACKGROUND ART FIG. 8 is a schematic side view of a conventional three-fish unloading device, and FIG. 9 is a front view of the rotary blade 3. In order to cut the fish body 1 into three pieces, the fish body 1 from which the head and internal organs have been removed in advance is held and conveyed by a pair of conveyor belts 2 with its back facing up, and the fish body 1 is cut into three pieces by a pair of rotating blades 3. Cut into fillet and back bone, 3
It was sold in bulk.

As shown in FIG. 9, the pair of rotary blades 3 are
Each has a rotating shaft 3a, and is rotationally driven around the axis of the rotating shaft 3a. Each rotating shaft 3a is provided to be inclined with respect to the horizontal plane, so that the peripheral edge of the rotating blade 3 is provided close to each other, for example near the upper part in the vertical direction, and has a substantially inverted V shape with an angle θ1 expanded. arranged in a letter shape. Of the fish body 1 cut by such a pair of rotary blades 3, the back bone comes into contact with a guide member 5 arranged very close to the rotary blade 3 on the downstream side of the conveyance direction 4 with respect to the rotary blade 3. , and had fallen below the guide member 5.

In such a device for unloading three fish bodies, the guide member 5 is provided close to the rotary blade 3, and the backbone abuts against the guide member 5, making it possible to smoothly unload three fish bodies 1. I couldn't do it.

Another prior art technique for solving such problems is shown in FIG. The guide member 6 provided near the downstream side of the rotary blade 3 in the conveying direction 4 has a width.
A guide groove 6a having W1 is provided. This allows the backbone to fall smoothly below the guide member 6 without hitting the guide groove 6a.

The three-piece unloading device provided with such a guide member 6 can be used only when the fish body 1 is unloaded into three pieces. Therefore, when the fish body 1 is opened, it is possible to use the three-piece unloading device shown in FIG. 11. As shown in the figure, the rotary blades 3 separate from each other near the tail of the fish body 1, making it impossible to cut the midbone. Problems arise in that the tail remains connected nearby or the tail becomes separated from the fillet.

FIG. 12 is a perspective view of the vicinity of the guide member 7 of a conventional fish body opening device. The guide member 7 is provided with a pair of rotary blades 3 as in each of the prior art described above, and when the rotary blades 3 cut the fish body 1 into the fillet and back bone, the guide member 7 is clamped. The portions 7a prevent the mutually adjacent portions of the rotary blade 3 from separating as shown in FIG. 11. Therefore, the fillet and the backbone are reliably cut near the tail of the fish body 1, and a fillet with the tail remaining in the fillet can be formed.

In such conventional technology, the guide member 7 is not provided with a guide groove, and therefore the backbone ends up hitting as described above, causing the backbone to fall smoothly below the guide member 7. I couldn't do it. Furthermore, each conventional example has a fixed purpose and lacks convenience.

Problems to be solved by the invention The purpose of the invention is to solve the above-mentioned problems, to make it possible to unload and open three pieces of fish with one device, and to improve the processing efficiency of fish. An object of the present invention is to provide a fish processing device.

Means for Solving the Problems The present invention provides a pair of blades each facing upstream in the transport direction of a fish whose head and internal organs have been removed and which is transported with its back up, and each blade is a pair of blades that are close to each other at their upper apex. a cutter, a guide member that guides the part of the fish processed by the cutter and includes a clamping part and a guide part, and a pressing member that presses the back of the fish processed by the cutter. , the holding part has a cross section perpendicular to the longitudinal direction roughly formed in an inverted V shape, and an inverted V-shaped end face is vertically disposed from the upper apex of the cutter to support each blade of the cutter. the guide part is connected to the clamping part, the inner circumferential surface of the connecting part is open to receive the processed fish body, the back part is closed, and the inner circumferential surface of the back part is closed. is formed to have an arcuate cross-section and is open at the lower surface, and the pressing member is capable of adjusting the distance l1 in the vertical direction between the back of the fish to be transported and the proximal portion of each blade of the cutter. This is a device for removing and opening three pieces of fish.

Effect According to the present invention, the blades of the pair of cutters face the upstream side in the transport direction of the fish body, and the blades are provided close to each other at the upper vertex. The part of the fish body processed by this cutter is guided by a guide member. The guide member includes a holding part that holds the cutter in the vicinity of a position close to the cutter blade, and a guide part that is integrally formed with the holding part and guides the fish body part. The holding portion prevents the blades of the cutter from separating at positions close to each other, thereby making it possible to reliably perform the desired treatment on the fish body part. Furthermore, the guide section allows the fish body part to be smoothly guided. Therefore, the working efficiency of fish processing can be improved.

Also, while pressing the back of the fish to be processed by the cutter with a pressing member, the vertical distance l1 between the back of the fish and the proximal part of the cutter is adjusted.
Process the fish so that it is cut into three pieces or opened.

Embodiment FIG. 1 shows a fish processing device 1 according to an embodiment of the present invention.
FIG. 2 is a schematic side view of 0, and FIG. 2 is a plan view thereof. Referring to FIGS. 1 and 2, the fish processing device 10 includes a pair of conveyor belts 13a and 13 for conveying the fish body 11 along the conveyance direction 12.
It has b. The conveyor belts 13a, 13b are each guided by a plurality of pairs of rollers 14. The fish body 11 from which the head and internal organs have been removed is transported along the transport direction 12 with the back facing up and the head at the front by the pair of transport belts 13a and 13b. A pair of rotary blades 15a, 15b, which are cutters, are disposed midway in the conveyance direction 12 of the conveyor belts 13a, 13b.

The rotary blades 15a, 15b are arranged to face each other, have a generally disk shape, and have rotating shafts 16a, 16b, respectively. Rotating shaft 16a, 1
6b are provided at an angle with respect to the horizontal direction, and thereby the rotary blades 15a, 15b
For example, at the vertically upper vertex, the rotary blade 15
The peripheral edges of the blades a and 15b are very close to or in contact with each other, and the rotary blade 15 is
a and 15b are provided apart from each other, and are arranged in an inverted V-shape expanded by a rough angle θ2 as in the conventional case. The fish body 11, which has been conveyed by the pair of rotary blades 15a and 15b while being held between the conveyor belts 13a and 13b, is transferred to the fillet 11a and the backbone 11.
It is cut into b.

A guide member 16 is arranged near the downstream side of the rotary blades 15a, 15b in the conveying direction 12. With this guide member 16, the fillet 11a and back bone 1 of the fish body 11 cut by the rotary blades 15a and 15b are
1b are separated. The fillet 11a is sent to the downstream side in the conveying direction 12 roughly along the outer peripheral surface of the guide member 16, and the backbone 11b is dropped below the guide member 16 along the inner peripheral surface of the internal member.

A roughly plate-shaped pressing member 20 is arranged close to the guide member 16 on the upstream side of the pair of rotary blades 15a, 15b in the conveyance direction 12. The pressing member 20 is
It can move up and down along the vertical direction of the conveyance direction 12. As a result, the conveyor belts 13a, 13b
The rotary blade 1 of the fish body 11 that has been conveyed while being held by the
It becomes possible to adjust the vertical position with respect to 5a and 15b. As a result, the position of the pressing member 20 is determined in accordance with the purpose of processing the fish body processing apparatus 10 of this embodiment for removing or opening three fish bodies 11. Therefore, the fish body 11 is the rotary blade 15
The position when abutting against a and 15b is determined.

3 is a side view of the vicinity of the guide member 16, FIG. 4 is a front view of the vicinity of the guide member 16, and FIG. 5 is a schematic perspective view of the guide member 16. Referring to FIGS. 3 to 5, the guide member 16 is roughly composed of a holding part 17 and a guide part 18. The clamping portion 17 has a cross section perpendicular to its longitudinal direction that is roughly formed in an inverted V shape, and the end face of this inverted V shape is vertically extended from the upper apex of the pair of rotary blades 15a and 15b. The rotary blades 15a and 15b are arranged so as to sandwich the rotary blades 15a and 15b. As a result, the pair of rotary blades 15a, 15b are kept close to each other, and for example, when the backbone 11b of the fish body 11 is cut by the rotary blades 15a, 15b near the tail of the fish body 11, the rotary blades 15a, 15b are prevented from separating from each other, and the back bone 11b can be reliably cut.

The guide part 18 of the guide member 16 is connected to the downstream side of the holding part 17 in the transport direction 12, and the connected part is connected to the rotary blade 15 so that the processed fish body bones enter therein.
It opens facing a and 15b. A back surface portion 18a that closes the guide portion 18 on the downstream side in the conveyance direction is arranged so as to extend from the inner circumferential surface 17a of the holding portion 17 so as to have an arcuate cross section. The lower surface of the guide portion 18 expands and becomes open as it goes downward in the vertical direction. As a result, the fish body 1 cut by the rotary blades 15a and 15b
Of the fillet 11a and the backbone 11b of 1, the backbone 11
b can be smoothly dropped below the guide member 16 along the inner circumferential surface of the back surface portion 18a of the guide portion 18. At this time, the dimension W2 of the guide part 18 is formed relatively large, and the length from the end face of the clamping part 17 to the back surface part 18a (the total length in the longitudinal direction of the guide member 16) is equal to the length of the middle bone of the fish to be processed. If the lengths are approximately equal, the backbone 11b can fall smoothly below the guide member 16 without being caught by the guide portion 18.

FIG. 6 is a schematic cross-sectional view showing the process of opening the fish body 11. The steps for opening the fish body 11 will be described with reference to FIGS. 1 and 2. When opening the fish body 11, conventionally the fish body 11 is opened with the tail attached to the fillet part 11a.
Consumers want to cut and separate the
In view of this, first, the fish body 11 that has been conveyed along the conveyance direction 12 while being held between the conveyor belts 13a and 13b is cut by a pair of rotary blades 15a and 15b, as shown in FIG. is started.

At this time, the dimension l1 from the contact part of the rotary blades 15a, 15b to the pressing member 20 is determined in advance, and the fillet 11a of the fish body 11 is determined by this dimension l1.
This prevents the blades from being cut and separated by the rotary blades 15a and 15b. Also, the rotary blades 15a, 15
The pressing member 20 prevents the fish body 11 from moving away in the radial direction of the rotary blades 15a, 15b due to the centrifugal force caused by the rotation of the rotary blades 15a, 15b. Therefore, the back of the fish 11 can be uniformly connected from the vicinity of the head to the vicinity of the tail of the fish 11 with the dimension l1.

Furthermore, the midbone 11b is located approximately at the center of the fish body 11, and near the start of cutting the fish body 11, the midbone 11b
The dimension l2 from 1b to the pressing member 20 is a relatively large value, so the rotary blades 15a,
The fillet 11 is cut by cutting the fish body 11 with the cutter 15b.
a and the backbone 11b can be reliably separated.

As the fish body 11 is further conveyed downstream in the conveyance direction 12 by the conveyor belts 13a and 13b, the body of the fish body 11 becomes smaller as shown in FIG. The dimension l3 from 20 to the backbone 11b also gradually becomes smaller.

Further, as shown in FIG. 6 and 3, when cutting near the tail of the fish body 11 is performed, the dimension l4 from the backbone 11b to the pressing member 20 becomes smaller than the dimension l1. Therefore, the backbone 11b is the rotary blade 15.
It passes through the contact portion between a and 15b, and the backbone 11b is cut. At this time, the middle bone 11b
are relatively hard and the rotary blades 15a, 15b are relatively thin, so although the rotary blades 15a, 15b tend to separate from each other,
Since the rotary blades 15a and 15b are vertically sandwiched from the upper apex portions near the rotary blades 15a and 15b, the rotary blades 15a and 15b do not separate from each other, and therefore the backbone 11b is It becomes possible to cut reliably.

In this way, from the pressing member 20 to the rotary blades 15a, 1
By predetermining the dimension l1 to the proximal portion of 5b, it becomes possible to open the fish body 11. Further, by further reducing the dimension l1, and therefore by changing the relative position between the vertical position of the fish body 11 and the contact position of the rotary blades 15a and 15b, the dimension l1 can be reduced to 0. By bringing the fish body 11 closer to the fillet 11a,
The backbone 11b with the tail attached can be cut and separated into what is called a three-piece cut.

In this way, in the fish body processing apparatus 10 of this embodiment, by changing the vertical position of the pressing member 20, the fish body 11 and the rotary blade 15a,
The relative positional relationship with 15b can be changed. This makes it possible to open the fish body 11 or to open three fish bodies. Therefore, fish body 1
There is no need to separately provide a device exclusively for unloading three pieces of fish 11 or a device exclusively for opening the fish body 11.

FIG. 7 shows a guide member 21 of another embodiment of the present invention.
It is a side view of the vicinity. The guide member 21 has a roughly semicircular side surface and includes a holding part 22 and a guide part 23 . The clamping portion 22 is provided to surround the rotary blades 15a and 15b similarly to the above embodiment.

The guide portion 23 of the guide member 21 is connected to the clamping portion 22 and has a guide surface 23a. This guide surface 23a can be formed more smoothly on the inner circumferential surface 22a of the holding portion 22 than the guide member 16 in the above-described embodiment.
It is installed in series from Therefore, even more
It becomes possible for the backbone 11b to fall below the guide member 21 without hitting the guide surface 23a, and it is possible to expect the same effect as in the above embodiment.

Effects As described above, according to the present invention, a guide member is provided in a pair of cutters in which the blades are provided so that their upper apexes are in contact with each other. This guide member is
It has a clamping part that clamps each of the blades at a contact position, and a guide part that guides the part of the fish processed by the cutter and is integrally formed with the clamping part.
This clamping part is configured such that the inverted V-shaped end face in the longitudinal direction is vertically disposed from the upper apex of the cutter and clamps each blade of the cutter, so that when cutting the middle bone of the cutter, it is most closely aligned with the cutter. Since the upper apex of the cutter, which is subject to stress, can be held between the longitudinal end surfaces of the clamping part, when cutting hard parts such as the middle bones of fish, the cutter can be reliably cut without moving away from the left and right, and it is also possible to cut small diameter Since even a small cutter can reliably cut the backbone, the cutter can be made smaller to save space and reduce costs.

Further, among the fish bodies processed by the cutter, the backbone can be reliably dropped below the guide member by the guide portion of the guide member, and work efficiency can be improved. Furthermore, a pressing member is provided to press the back of the fish being transported with its back up, and this pressing member is used to measure the distance in the vertical direction between the back of the fish being transported and the proximal portion of each blade of the cutter.
Since l1 can be adjusted, the above distance l1 is
It also has the unique effect of being able to set the distance to take out three fish bodies and open them, so that one device can be used for both taking out three fish bodies and opening them.
