Description

  The present invention relates to a device for aligning the dorso-ventral direction of fish, particularly saury, in a certain direction.

  Conventionally, when a fish body whose head is directed in the transport direction by an oscillator or the like is carried on the conveyor and the head cutting process or the laparotomy process is performed, the dorso-ventral direction of all the fish bodies is directed to a certain direction. It is necessary to make these processes possible.

  As an apparatus for aligning the dorsal abdominal direction, for example, as described in Patent Document 1, the width between the vertical wall plates on both sides is gradually narrowed toward the conveyance direction, and the fish body is raised from the lying state. A first passage that is in communication with the first passage, and the two vertical wall plates are gradually inclined to one side, whereby the standing fish body is inclined so that its back portion is directed in a certain direction. A device has been developed that includes a passage and a rotating brush that forcibly feeds fish from the first passage to the second passage on the first passage.

  The cross-sectional shape of fish, especially saury, is thicker on the back side and the abdomen has a thin inverted triangle. Therefore, if it is supplied into the first passage in this state, the back and abdomen are pressed against the opposing wall surfaces of the both vertical wall plates while passing through the first passage, and then gradually compressed. With the abdomen received on the inner surface of the lower end of one vertical wall board as a fulcrum, the back part received on the inner side of the other vertical wall board is lifted upward at a position above this abdomen and is in an upright state After that, it enters the second passage and inclines in the inclination direction of the vertical wall plates on both sides of the second passage, so that the dorsal-abdominal direction of all fish bodies (saury) is directed to a certain direction.

Japanese Patent Publication No. 2-57892

  However, according to such a fish body dorsal and ventral direction aligning device, regardless of the size of the fish body, that is, the width between the dorsal belly, the width between the vertical wall plates on both sides of the first and second passages is as follows. Since it does not fluctuate, it is necessary not only to set the entrance width of the first passage to a width that can accept the largest fish body, but also to the opposite wall surfaces of the vertical wall plates on both sides of the first passage as well as the smaller fish body. The distance until the back and abdomen comes into contact with each other becomes longer, and the entire apparatus becomes larger. In addition, when the passage width of the first passage is abruptly narrowed toward the second passage so that the fish body stands up for a short distance, the dorsal belly that presses against the vertical wall plates on both sides thereof. This increases the frictional resistance of the rotating brush and makes it difficult to pass through the passage despite the feeding force of the rotating brush.

  Furthermore, the dorsal belly portion of the fish that abuts the opposing wall surfaces of the vertical wall plates on both sides of the first passage is only the portion having the largest width dimension (fish body height) between the dorsal belly. A large clamping force is required to stand the whole fish body, and the frictional resistance between the opposing wall surface of the passage and the back of the fish body further increases, coupled with the frictional resistance of the fish sliding in the first and second passages. There is a problem that the process of aligning the direction of the stomach direction cannot be performed smoothly.

  The present invention has been made in view of such problems, and the object of the present invention is to squeeze the dorsal belly portion from the head to the tail, regardless of the size of the fish, and instantly An object of the present invention is to provide an apparatus for aligning the dorso-ventral direction of fish that can reliably and efficiently direct the dorso-ventral direction of all fishes in a certain direction.

  In order to achieve the above object, the fish body dorsal and ventral direction aligning device according to the present invention has an upper half portion formed on an outwardly inclined peripheral surface inclined in the diameter-expanding direction toward the upper end as described in claim 1. And a pair of left and right dorsal and abdominal direction fish sandwiching rollers comprising a roller formed on an inwardly inclined circumferential surface whose upper half is inclined in the diameter-reducing direction toward the upper end. The fish passing through the body is arranged so that it can be clamped from both sides, the interval between these fish clamping rollers can be expanded and contracted, and is biased in the direction of approaching each other by a spring force. It has a structure in which a feeding means for feeding the fish body is provided between the fish body pressure rollers through the conveyance path.

  In the fish body dorsal and ventral direction aligning device configured as described above, the invention according to claim 2 is characterized in that the pair of left and right arms are attached to the distal ends of the left and right arms whose base end portions are supported so as to be reciprocally turnable on both sides of the fish transport passage. The fish body pressure rollers are rotatably supported by supporting shafts, and the supporting shafts are connected by a tension spring.

  Further, the invention according to claim 3 is a rotating brush driven by a motor as fish feeding means between the fish pinching rollers, and the tip of the brush on the lower peripheral side is inserted into the fish carrying passage. And it is configured to rotate in the feeding direction of the fish body.

  According to the first aspect of the present invention, since the pair of left and right fish sandwiching rollers are biased toward each other by the spring, regardless of the size of the fish, the width dimension between the dorsal belly of the fish is further increased. Despite the change in the length direction, when the fish lying in a state lying between these pinching rollers is fed by the feeding means, the width dimension between the dorsal belly over the entire length from the head to the tail The pressure between the rollers can be continuously reduced by expanding or reducing the width between the rollers in accordance with the change of the pressure. At that time, first, the head is clamped by the clamping roller and starts to stand up, and the head standing operation is transmitted to the body part following the head to start standing up, When the head side starts to stand up, the inclination angle of the line connecting the vertices between the back and abdomen (hereinafter referred to as the center line) with respect to the horizontal plane increases, and the body part passes through the pinching roller, so that the pinching force is relatively small. Therefore, since the width between the dorsal belly is larger on the body part side than the head part, the space between the pressure rollers for clamping the body part is widened, and accordingly, between these rollers. The spring force urging in the narrowing direction increases, so that the clamping force to be raised becomes large and the body portion can be instantly and reliably raised when passing between the clamping rollers.

  In addition, the pinching of the fish by the pinching rollers is performed while these pinching rollers are automatically rotated in the direction of travel according to the progress of the fish, so there is almost no frictional resistance against the fish and the fish is smooth. In addition, it is possible to reliably stand up within an extremely short traveling distance while passing quickly.

  Further, in the pair of left and right pressing rollers, the upper half of one roller is formed on an outwardly inclined peripheral surface inclined in the diameter increasing direction toward the upper end, and the upper half of the other roller is contracted toward the upper end. Since it is formed on an inwardly inclined peripheral surface that is inclined in the radial direction, when the fish stands as described above, both side surfaces of the back portion are sandwiched between the upper half portions of these rollers, The center line of the fish body is inclined in the inclination direction of these inclined surfaces by the outward inclined peripheral surface and the inward inclined peripheral surface of the other roller, and in this state, it passes between the pinching rollers instantaneously. All fishes fed between the pressure rollers can be laid in that direction sequentially and reliably and efficiently with their backs in the inclined direction.

  According to the second aspect of the present invention, the pair of left and right fish sandwiching rollers are respectively supported on the distal ends of the left and right arms, whose base ends are supported so as to be reciprocally turnable on both sides of the fish transport path. Since these support shafts are connected to each other by a tension spring, the pair of left and right fish sandwiching rollers can be accurately arranged at predetermined positions on the fish transport passage with a simple structure. In addition, it is possible to accurately and quickly align the dorsal abdominal direction by applying a uniform clamping force from the head to the tail on both sides of the fish passing between these clamping rollers.

  According to a third aspect of the present invention, the fish feeding means between the fish sandwiching rollers comprises a rotating brush that is driven to rotate by a motor, and the tip of the lower peripheral side brush is placed in the fish carrying path. Since it is configured to be inserted and rotated in the feeding direction of the fish body, the fish body is sequentially inserted between the pair of left and right pressure rollers from the fish body conveyance passage one after another at a high speed. In addition to being able to feed by rotational force, it can pass between the pressing rollers instantly and the direction of the dorsal belly can be directed to a certain direction, enabling high-speed processing of 150 animals / minute or more. Automatic processing line can be achieved.

(A)-(D) is the front view which cut through a part which shows the alignment processing state of the saury of the saury which turned the back part side to the other pinching roller side.

  Next, a specific embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, reference numeral 1 denotes a conveyance passage having a width through which a lying saury F can pass, and the width between the backs of the saury F The side wall plates 1b and 1b of a certain height are integrally erected on both sides of the horizontal bottom plate 1a which is wider than the height of the saury, and is formed into a straight bowl shape with a U-shaped cross section. Both side wall plates 1b, 1b in the middle of the length direction of the passage 1 are excised, and the both sides excised portions 1c, 1c are formed in the introduction passage 1A on the upstream side and in the outlet passage 1B on the downstream side, and both sides are excised. A pair of left and right anti-abdominal direction sammer pinching rollers 2 and 3 for pinching the saury F passing through the conveying passage 1 through the portions 1c and 1c from both sides are provided.

  As shown in FIGS. 4 and 5, the pair of nipping rollers 2 and 3 are formed such that the lower half portion of the circular outer circumferential surface is formed on the vertical circumferential surfaces 2 a and 3 a, and one of the nipping rollers The upper half of 2 is formed as an outwardly inclined peripheral surface 2b inclined in the diameter increasing direction from the upper end of the vertical peripheral surface 2a toward the upper end of the pressing roller 2, and the upper half of the other pressing roller 3 is formed. Are formed on an inwardly inclined peripheral surface 3b inclined in a diameter-reducing direction from the upper end of the vertical peripheral surface 2b toward the upper end of the pressure roller 3, and the inner and outer inclined peripheral surfaces 2b and 3b are parallel to each other. Further, the height (length) of the pinching rollers 2 and 3 is such that when the sammer F is pinched by the pinching rollers 2 and 3 to stand, The abdomen f1 is formed at a height at which the abdomen f1 is located on the lower half side and the back part f2 is located on the upper half side.

  The pair of pinching rollers 2 and 3 is rotatably supported at the center of rotation by vertical shafts 4 and 5 and these shafts 4 project upward from the upper ends of the pinching rollers 2 and 3. The upper end of 5 is connected and supported in a suspended state by the distal ends of a pair of left and right arms 6 and 7. Further, the base end portions of the pair of left and right arms 6 and 7 are arranged horizontally on the bearings 8 and 9 on the both sides of the transport passage 1 on the side of the introduction passage 1A with a certain distance from the introduction passage 1A. The pair of left and right pressing rollers 2 and 3 supported at the ends of these arms 6 and 7 are pivotally attached to the arms 6 and 7 so that the cut portions 1c of the side wall plates 1b and 1b in the transport passage 1 are provided. , 1c facing the conveyance path, and the space between the opposed peripheral surfaces is disposed at the central portion in the width direction of the conveyance path 1 so as to be freely expandable and contractable. The ends of a tension spring 10 made of a coil spring are connected to the upper ends of the springs 5, respectively, and the space between the pressure rollers 2 and 3 is constantly reduced by the tensile force of the spring 10, that is, the pressure rollers 2, 3 Are biased in the direction of approaching each other.

  Above the introduction passage 1A in the transport passage 1, a rotating brush 11 is provided which has a large number of brushes 11b of a certain length radially projecting on the outer peripheral surface of the disk 11a. The tip of the brush 11b is inserted into the introduction passage 1A, and the tip is brought close to the bottom surface of the introduction passage 1A. A rotating shaft 12 perpendicular to the length direction of the conveying path 1 is passed through the center of the disk 11a of the rotating brush 11 so that the disk 11a is fixed to the rotating shaft 12 integrally. The base end is connected to a drive motor 13 installed on one side of the introduction passage 1A, and the tip is rotatably supported by a bearing body 17 fixed to the other side of the introduction passage 1A. Then, the lower peripheral side inserted into the introduction passage 1A of the rotating brush 11 is rotated toward the pair of pressure rollers 2 and 3 by the drive motor 13, and the sammer F supplied to the introduction passage 1A is rotated. It is configured to feed between the pair of nipping rollers 2 and 3.

  On the downstream side of the pair of nipping rollers 2 and 3 above the entrance side of the lead-out passage 1B, a frustoconical auxiliary guide roller 14 that is close to the nipping rollers 2 and 3 is the same as the rotating brush 11 A shaft 18 is rotatably supported in the direction. The auxiliary guide roller 14 has a large diameter at one end of the outer peripheral surface facing one of the nipping rollers 2 whose upper half is formed on the outward inclined peripheral surface 2b, and the upper half is the inward inclined peripheral surface 3b. Is formed on an inclined outer peripheral surface that gradually decreases in diameter toward the outer peripheral surface facing the other nipping roller 3 formed on the back side, and the back portion f2 is formed on the inward inclined peripheral surface 3b side of the other nipping roller 3. The back portion f2 of the saury F that passes between the pressure rollers 2 and 3 while being inclined toward the surface is configured to be actively tilted in the inclined direction on the inclined outer peripheral surface thereof.

  The fish body (Saury F) dorsal and abdominal direction aligning device configured as described above includes, for example, a Saury feeding inclined passage 15 from an oscillator (not shown) that aligns all the heads of the Saury F so as to be all the heads. For the head cutting process, etc., in which the inlet of the introduction passage 1A of the conveyance passage 1 is in communication with the downwardly inclined end and the outlet of the lead-out passage 1B of the conveyance passage 1 operates in a direction perpendicular to the outlet. It is installed in a state where it faces over one side edge of the conveyor 16.

  The saury F fed into the introduction passage 1A of the transport passage 1 in a recumbent state with the head facing the leading side (conveyance side) through the inclined passage 15 from the oscillator side is oriented on one side or the other side It is in a state towards the direction. Further, as shown in FIG. 6, the fish body, particularly saury F, has an inverted triangular cross-sectional shape that is thick at the back f2 side and thin at the abdomen f1 side at both the head f3 and the trunk. Therefore, in the recumbent state, a center line Y (shown in FIG. 5) connecting the apexes of the back part f2 and the abdomen is inclined obliquely upward from the abdomen f1 toward the back part f2.

  In this way, when the saury F in the lying state in which the direction of the dorsal belly direction is indefinite is supplied into the introduction passage 1A of the conveyance passage 1, the introduction passage 1A in the position near the rear of the pair of left and right pressing rollers 2 and 3 The sammer F is fed between the pinching rollers 2 and 3 by the rotational force of the rotating brush 11 disposed above. The rotating brush 11 is rotated at a high speed by a drive motor 13, and the sammer F supplied to the introduction passage 1A of the conveying passage 1 is quickly sent between the pressure rollers 2 and 3 one after another and the pressure roller 2 by the rotational force. Pass between three.

  At this time, a saury F is interposed between the pressing rollers 2 and 3 from the head side with the back portion f2 facing the one pressing roller 2 side, the upper half of which is formed on the outward inclined peripheral surface 2b. When the head f3 is fed, when the head f3 passes between the pressure rollers 2 and 3, as shown in FIG. The head f3 is clamped by the vertical peripheral surfaces 2a and 3a of the lower half thereof by the elastic force of the tension spring 10 while being spread against the tension. Then, the top side of the head f3 which is in pressure contact with the lower half vertical peripheral surface 2a of one of the pressure rollers 2 is pressed against the vertical peripheral surface 3a of the lower half of the other pressure roller 3 by this clamping pressure. As shown in FIG. 7 (b), standing is started along the vertical peripheral surface 2a with the thin-walled jaw side as a fulcrum.

  That is, since the center line Y of the head is inclined obliquely upward from the other pinching roller 3 side toward the one pinching roller 2, the jaw is formed by the lower end of the vertical peripheral surface 3a of the other pinching roller 3. Is pressed against the bottom surface of the conveying path 1 so as to be drawn toward the one pressing roller 2 side, and the head is moved by the intermediate portion of the vertical circumferential surface 2a of the one pressing roller 2 in the height direction. While lifting the top of the part, the head is moved so as to be drawn toward the other pressing roller 3 side.

  This standing force, which is the lifting force of the head, is transmitted also to the trunk part continuous from the head f3, and when the trunk part passes between the pinching rollers 2 and 3, as shown in FIG. From the standing angle of the head f3, the head is further raised in the vertical direction. That is, the back portion f2 and the abdominal portion f1 are pinched by the pair of pinching rollers 2 and 3 that move in the direction of being pulled toward each other toward the central portion in the width direction of the conveyance path 1 by the force of the tension spring 10. However, the inclination angle of the center line Y is further increased. Specifically, the other nipping roller 3 that receives the abdomen f1 moves toward the one nipping roller 2 while pushing the abdomen f1 along the bottom surface of the conveyance path 1 to the one nipping roller 2 side. One pressing roller 2 that receives the portion f3 moves toward the other pressing roller 2 while the lower portion f2 is received at the lower end of the other pressing roller 2 with the back portion f2 as a fulcrum. The nipping roller 2 is lifted while sliding from the upper end of the vertical circumferential surface 2a to the outward inclined circumferential surface 2b of the upper half.

  When the space between the pinching rollers 2 and 3 is narrowed by the pulling force of the tension spring 10 and the saury F is further pinched from the vertically standing state, as shown in FIG. The upper half of one side surface of the pressure roller 2 is pressed against the outwardly inclined peripheral surface 2b of the pressure roller, and the back portion f2 is lifted from the vertically standing state by the pressing force from the outwardly inclined peripheral surface 2b. The other side surface of the body portion facing the other pressure roller 3 is pushed toward the other pressure roller 3 side and is received by the inwardly inclined peripheral surface 3b of the other pressure roller 3 so as to be centered. The line Y is inclined toward the other pinching roller 3 from the lower end of the abdomen f1 toward the top of the back portion f2, and in this state, the sammer F is passed between the pinching rollers 2 and 3 while being pinched to the tail.

  The pinching of the saury F by the pinching rollers 2 and 3 is performed while rotating the pinching rollers 2 and 3 by the sliding contact force when the sammer F passes with respect to the outer peripheral surfaces of the pinching rollers 2 and 3. Therefore, almost no frictional resistance is generated between the saury F and the pinching rollers 2 and 3, and the sammer F can be passed smoothly while standing. Further, the sammer F is erected so as to be instantaneously passed between the pressure rollers 2 and 3 by the rotational force of the rotary brush 11 and inclined toward the inwardly inclined circumferential surface 3b of the other pressure roller 3. The sent saury F can be quickly processed one after another.

  The sammer F fed from between the pair of pressure rollers 2 and 3 in a state where the back portion f2 is received by the inwardly inclined circumferential surface 3b of the other pressure roller 3 is It passes through the lower peripheral surface of the auxiliary guide roller 14 disposed above the outlet-side outlet passage 1B while making one side of the back portion f2 slidably contact it. The auxiliary guide roller 14 is formed on an inclined peripheral surface having a gradually decreasing diameter from the one pressing roller 2 side having the outward inclined peripheral surface 2b toward the other pressing roller 3 having the inward inclined peripheral surface 3b. Therefore, the inclined circumferential surface presses one side surface of the back portion f2 facing the one sandwiching roller 2 in the saury F inclined to the inwardly inclined circumferential surface 3b side of the other sandwiching roller 3. The saury F is forcibly pushed down so that its back portion f2 faces the other side wall plate 1b side of the lead-out passage 1B, and the abdomen f1 is placed on its side facing the one side wall plate 1a side of the lead-out passage 1B from the lead-out passage 1B. Discharge onto conveyor 16.

  On the other hand, the state where the upper half of the back f2 side opposite to the above from the oscillator side through the inclined passage 15 is directed to the other pressing roller 3 side formed on the inwardly inclined peripheral surface 3b, that is, the center line When the sammer F is fed from the head side between the pressing rollers 2 and 3 while Y is inclined obliquely upward from the one pressing roller 2 side toward the other pressing roller 3, When passing between the nipping rollers 2 and 3 from the f3 side, as shown in FIG. 8 (a), they are nipped by the lower half portions of these nipping rollers 2 and 3 which are attracted to each other by the tension spring 10. The inclination angle of the center line Y increases as the distance between the pressing rollers 2 and 3 is reduced by the spring force. That is, while the jaw (abdomen f1) is received by the lower end of the lower half of one of the pressure rollers 2, it is pushed toward the center along the bottom surface of the conveyance path 1 and the other pressure roller 3 The head f3 (back part f2) received by the vertical peripheral surface 3a of the lower half part of the pinching roller 3 as shown in FIGS. 8 (b) and (c) with the jaw part (abdomen f1) as a fulcrum. The vertical peripheral surface 3a is lifted while being in sliding contact with the inwardly inclined peripheral surface 3b.

  When the back portion f2 reaches the inward inclined peripheral surface 3b of the pressure roller 3 and comes into contact with the inward inclined peripheral surface 3b, as shown in FIG. In the same manner as the standing posture shown in FIG. 7 (d) in which the back portion f2 is erected from the state in which the back part f2 faces toward the one pressure roller 2 without standing up to the vertical state, the inwardly inclined circumferential surface. The both sides of the back part f2 are clamped by the outward inclined peripheral surface 2b and the inward inclined peripheral surface 3b of the pressing rollers 2 and 3 at substantially the same inclination angle as 3b. Passing between the pressure roller 2 and 3 while rotating.

  In this way, the saury F fed from between the pair of the pressing rollers 2 and 3 in a state where the back portion f2 is received by the inward inclined peripheral surface 3b of the other pressing roller 3 is as described above. One side surface of the back portion f2 of the sammer F that is inclined toward the inwardly inclined circumferential surface 3b side of the other pinching roller 3 by the inclined circumferential surface of the auxiliary guide roller 14 is opposed to one side. Press and forcibly push down so that the back portion f2 faces the other side wall plate 1b side of the lead-out passage 1B, and put the abdomen f1 in a lying state toward the one side wall plate 1a side of the lead-out passage 1B. 16 is discharged on top. Accordingly, even if the direction of the dorsal abdominal portion of the saury F sequentially supplied from the tail oscillator side is directed to the left or right direction, the pair of left and right pressing rollers 2 and 3 are all directed to the same direction. Can be processed.

  Instead of the auxiliary guide roller 14, a pressing guide plate that presses the upwardly inclined side surface of the back portion f2 of the saury F passing between the pinching rollers 2 and 3 on the entrance side of the outlet passage 1B is forcibly used. You can push it down. The pressing plate is formed so that the height of the lower surface that presses the back portion f2 of the saury F gradually decreases toward the downstream side, and is formed so as to push down the saury F on its lower surface.

  When such an auxiliary guide roller 14 or a pressing guide plate is used, the saury F that has passed between the pinching rollers 2 and 3 can be laid down in a short distance with its back f2 oriented in a certain direction. Although it can be supplied directly from the outlet passage 1B to the conveyor 16 for head processing without the need for conveying force, the rotational force of the rotating brush 11 can be obtained without using the auxiliary guide roller 14 or the pressing guide plate. Accordingly, the saury F can be sent between the pressure rollers 2 and 3 and passed through to slide down on the lead-out passage 1B to the downside state. The device for aligning the dorso-ventral direction of the fish body of the present invention is not limited to saury F, and if the fish body has a wide back part f2 and a narrow abdomen f1, the dorso-ventral direction can be all directed in a certain direction.
