Description

The present invention relates to a device and method for automatically opening a sarcolemma ovary membrane that can automatically open (split) the ovarian membrane of a muscular covering (enveloping) a large number of eggs of salmonids.
In the present specification, the term “muscle” refers to a state in which a large number of fish eggs are covered with an ovarian membrane. For example, a typical example is a state in which a large number of fish grains such as salmon and sea bream are wrapped in an ovarian membrane. And are all covered within the scope of the present invention.

A “muscle” covers a large number of fish eggs by ovarian membranes such as muscles (stripe), and the fish eggs from which the ovarian membrane is removed and separated one by one is called a salmon roe or rose.
Conventionally, fish eggs such as salmon rosa have been separated into individual pieces by hand as shown in the following (1) and (2).
(1) "Opening work"
Move each muscle to the workbench, hold the muscle with one hand, and open (split) the ovarian membrane with a knife.
(2) “Hand-grip work”
Next, a large number of fish eggs adhering to the opened (split) ovarian membrane are hand-picked and separated into individual pieces (hand-grip work).

  Such an operator's own opening and hand-grip work requires considerable skill. Therefore, since the number of people who perform such work is limited, the fatigue level of full-time workers is considerable. Also, workers are working with gloves to make it difficult to slip, but such fish eggs are quite oily, and there is a problem that this oil entering from the gaps of work gloves causes rough hands It was the biggest trouble that nobody had. Furthermore, since it was performed manually as described above, it cannot cope with HACCP (Hazard Analysis Critical Control Point) in hygiene management. Also, if you use rubber gloves instead of gloves, you will not touch the hands of the workers directly, but even this is not good for hygiene because it does not change to manual work, but recently from gloves made of vinyl chloride resin Since the problem that environmental hormones were detected also occurred, such manual work was not preferable for food hygiene and HACCP compliance.

  Therefore, in order to eliminate such problems and problems, the applicant of the present application is used in the fish egg continuous separation device disclosed in Patent Document 1 and the fish egg continuous separation device disclosed in Patent Document 2. A fish egg slicing device is provided. By providing such a device, the operator's manual grind work, that is, the fish egg grain separation work (pretreatment process) in which the worker grabs by hand and separates the egg grains from the ovarian membrane one by one is mechanized. In addition to solving the above-described problems, it was possible to obtain further excellent effects.

However, even if the problem at the stage of manual massage can be resolved, the same problem has occurred because the work of opening the ovarian membrane of the muscles one by one (the opening of the muscles) still relies on the worker's manual work. There were still issues that had not been resolved.
In other words, in order to open the ovarian membrane with a blade without damaging (smashing) the fish egg grains, it was necessary to rely on the manual work of skilled workers.
In particular, in the case of relatively expensive fish eggs such as salmon roe, the most important issue is to separate them one by one with a good yield. The problem remains whether the ovarian membrane can be opened automatically without damaging (smashing) the skin.
Accordingly, the applicant of the present application has conducted various studies on how to open the ovarian membrane continuously and automatically with a high yield, and as a result, the automatic opening device of the present invention has been completed.

  In the present embodiment, the conveyance unit 9 includes a flat belt receiving surface 2 provided above the gantry 1 and a first belt belt 12 provided on the gantry 1 near one end of the belt receiving surface 2. The drive pulley 10, the first driven pulley 11 for the conveyor belt 12 provided on the gantry 1 near the other end side, and the endless shape (ring-shaped) across the first drive pulley 10 and the first driven pulley 11. And a plurality of conveyor belts 12 that run in a predetermined direction (conveying direction indicated by an arrow 200 in FIGS. 1 to 7). In this embodiment, as shown in FIG. 2, five conveyor belts 12 are stretched.

The belt receiving surface 2 is a flat long stainless steel plate that slidably receives the back surface 16 side of the conveyor belt 12, and is detachably provided above the gantry 1.
The belt receiving surface 2 is provided with a large number of drain holes 3 (holes penetrating in the vertical direction of the plate) throughout the predetermined arrangement, and an area at one end of the belt receiving surface 2 in the plate length direction ( In a predetermined position between the right input region 4) in FIG. 1 and FIG. 2 and the other end region (left discharge region 6 in FIG. 1 and FIG. 2), a long hole is formed in the vertical direction (vertical direction). A penetrating opening 17 is formed (see FIGS. 3 to 8).
Various specifications such as the hole shape and hole diameter of the drain hole 3 and the interval (pitch) between the holes can be changed in design.
The belt receiving surface 2 is preferably designed so that there is no unevenness due to the edge of the drainage hole 3 or the like so that the frictional resistance is as low as possible because the back surface 16 side of the rotating conveyor belt 12 contacts.

  The first drive pulley 10 and the first driven pulley 11 are rotatably supported on the gantry 1, respectively. The first drive pulley 10 receives power from a drive source (motor) (not shown). It rotates in a predetermined direction.

In this embodiment, the length of the conveyor belt 12 is placed on the surface 15 of each conveyor belt 12. A guide wall 18 is disposed over a predetermined region in the vertical direction (the same direction as the transport direction 200).

The transport belt 12 is a belt for transporting food, and is preferably surface-treated so that the streaks 100 to be transported do not slip.
For example, in the present embodiment, a not-shown recess (a recess continuous over the left and right edges) and a protrusion (a protrusion continuous over the left and right edges) are the same as the belt length direction (conveying direction 200). Synthetic resin belts are used which are formed in an uneven surface shape alternately arranged over the direction).
It should be noted that the design of the belt surface 15 can be changed within the scope of the present invention, such as a belt-like surface formed on the belt surface 15 and a belt surface 15 formed with a number of intermittent recesses and protrusions.
Further, the design of the conveyor belt 12 can be arbitrarily changed, such as rubber or synthetic resin, and is not particularly excluded from being made of metal and is within the scope of the present invention.

The guide wall 18 is a member that divides the plurality of transport regions 8 side by side so as to guide the plurality of struts 100 in parallel so that they can be transported separately. 24 and the conveying area 8 of the strut 100 are formed so as to be surely guided to the film dividing part 30.
In the present embodiment, a plurality of long members 19 formed in a substantially inverted V shape (also referred to as a trapezoidal shape) in a cross-sectional view are arranged side by side at predetermined intervals, and are adjacent to each other. Respective inclined wall surfaces 20 of the corresponding long members 19 function as guide walls 18 (see FIG. 8).
Moreover, in this embodiment, it has the spanning member 23 spanned so that it might orthogonally cross each long member 19 on the upper surface of each long member 19, and it was formed integrally. 23 is detachably attached to the gantry 1.

The entire length of the long member 19 is determined by a position a predetermined distance away from the end on the loading region 4 side in the transport direction 200 and a midway position of the pressing portion 47 (for example, the second driving pulley 49 for the pressing portion). To the nearest position). The overall length of the long member 19 is not limited to the specification of the present embodiment. If it has a length that can guide the muscle 100 from the loading region 4 where the muscle 100 is placed on the device to the film splitting portion 30 that splits the muscle 100, the length is further increased. It may be a thing. For example, even a length extending from the input area 4 to the discharge area 6 is within the scope of the present invention.
In addition, each long member 19 constituting the guide wall 18 has a lower end (expansion side end portion) 21 disposed with a slight gap from the surface 15 of the conveyor belt 12 or a conveyor belt. 12 are arranged so as to make slight contact with the surface 15.
The distance between the lower end (end portion on the expansion side) 21 of the long member 19 formed in a substantially inverted V shape (also referred to as a trapezoidal shape) in a cross-sectional view is the same as that of the long belt 19. When positioned on the surface 15 and on the center line in the direction orthogonal to the width direction of the belt along the conveyance direction 200, the conveyance belt 12 is provided on both sides of the lower end (expansion side end) 21 of the long member 19. Is a width that remains with a predetermined width (the interval between the end portions on the expansion side is 22 and the width of the belt remaining on both sides of the lower end 21 is 12a).

Therefore, in this embodiment, a substantially V-shaped region in a sectional view partitioned by the opposing inclined wall surfaces 20 of the adjacent guide walls 18 functions as the conveying region 8 of the muscle 100 (see FIG. 1 and FIG. 1). 8), the opening 17 of the belt receiving surface 2 facing from a predetermined distance 13 (gap) between the adjacent conveyor belts 12 functions as an opening area in the conveyance area 8 (FIG. 3). -Refer to FIG. 8.) The upper surfaces of the adjacent conveyor belts 12 positioned in the conveyance area 8 delimited by the adjacent guide walls 18 function as the conveying surfaces 14 of the streaks 100 (FIG. 1).

That is, the blade portions 46 projecting from the inclined opposing sides of the blade pressing surface 35 and the blade pressing plate portion 40 are the inclined opposing sides of the blade pressing surface 35 and the blade pressing plate portion 40. It projects with the same inclination angle.
In the present embodiment, the blade portion 46 is described with a single blade, but even a double blade is within the scope of the present invention.

In the present embodiment, the membrane piercing portion 41 and the membrane splitting blade 44 have been described with the integral membrane splitting portion 30 provided in the main body portion 31, but the present invention is not construed as being limited thereto. Absent.
For example, the structure may be such that the membrane piercing portion 41 and the membrane splitting blade 44 are formed as separate members and attached to the gantry 1. Even when configured as a separate member in this way, the membrane piercing portion 41 is provided on the upstream side (injection region 4 side) in the transport direction 200, and the membrane cutting blade 44 is provided in the downstream side (discharge region 6 side). Shall be provided.
Further, the film split blade 44 provided as a separate member can be formed in any other shape such as a round blade within the scope of the present invention. It is also within the scope of the present invention to employ a rotary blade.

  In the present embodiment, a pressing unit 47 is provided that is disposed above the transport unit 9 and presses the string 100 transported by the transport unit 9 against the transport unit 9 side.

  In this embodiment, as shown in FIGS. 1 to 8, the pressing portion 47 acts to press the muscle 100 toward the conveying belt 12 at least above the opening area provided in the conveying portion 9. The second driving pulley 49 and the second driven pulley 50 for the pressing portion disposed at predetermined intervals, and a plurality of endless bridges spanning the second driving pulley 49 and the second driven pulley 50 And a plurality of belt pressing portions 52 that press the respective pressing belts 51 in the direction of the conveying belt 12. In the gantry 1, pressing that is detachably disposed above the conveying portion 9. Each of the unit main bodies 48 is provided.

The belt pressing unit 52 includes a first pressing roller 53 disposed near the second driven pulley 50, a third pressing roller 55 disposed near the second drive pulley 49, and the first pressing roller 53. It is comprised by the 2nd pressing roller 54 distribute | arranged at equal intervals between the pressing roller 53 and the 3rd pressing roller 55 (refer FIG. 1, FIG. 2).
The first pressing roller 53, the second pressing roller 54, and the third pressing roller 55 are moved up and down so that they can be lowered by their own weights toward the transport belt 12 and the presser belt 51 can be pressed toward the transport belt 12.

Direction).
That is, in this embodiment, the reason for adopting the configuration including the two presser belts 51 and 51 with a predetermined interval as described above is that the presser belt 51 is moved in the direction of the transport belt 12 (transported) by the belt pressing unit 52. This is to prevent the presser belt 51 from coming into contact with the film splitting portion 30 and damaging it when pressed in the direction of the surface 14) (damage of the presser belt 51 or damage to the film splitting portion 30).
In the present embodiment, a single belt pressing portion 52 is employed for the two presser belts 51, 51 to press the two presser belts 51, 51 simultaneously. , 51 can be provided with individual belt pressing portions 52 within the scope of the present invention.
Even if the presser belt 51 is set so as not to contact the membrane split portion 30, the presser belt 51 can be used as a single transport surface if the strut 100 can be sufficiently pressed in the direction of the transport belt 12 (the transport surface 14 direction). A single belt (a single belt having a width approximately equal to the total width when the two presser belts 51 and 51 are provided) may be employed for the belt 14.
In the present embodiment, the pressing portion 47 is provided as described above. However, in the present invention, the arrangement of the pressing portion 47 is arbitrary, and even if the pressing portion 47 is not provided, the operational effects of the present invention are achieved. It can be fully demonstrated.

  In this embodiment, since it is comprised as mentioned above, there exist the following effects.

[Input process (stitch transport process)]
First, the muscle 100 that is the target of film splitting of the ovarian membrane 101 is placed (loaded) on the transport surface 14 of the transport region 8 formed between the opposing inclined wall surfaces 20 of the adjacent guide walls 18. . The streak 100 placed on the transport surface 14 is transported from the input region 4 to the discharge region 6 by the transport belt 12 (conveyed in the transport direction 200). See FIGS. 1-3.

[Ovary membrane suction process]
Next, the streak 100 conveyed by the conveying belt 12 reaches a lower region of the pressing portion 47 and enters between the pressing belt 51 of the pressing portion 47 and the conveying belt 12.
Then, immediately below the first pressing roller 53, the ovarian membrane 101 is sucked downward of the transport surface 14 by the suction port 28 of the membrane sucking unit 24 arranged immediately below the first pressing roller 53. . See FIG.

[Ovarian membrane splitting process, muscle pressing process]
The muscle 100 is transported in a state where the ovarian membrane 101 is sucked into the suction port 28 by the membrane sucking step, and reaches the membrane splitting portion 30.
The muscle 100 that has reached the membrane splitting portion 30 is conveyed while the ovarian membrane 101 is first sucked into the suction port 28 and is pressed toward the conveying surface 14 by the first pressing roller 53 of the pressing portion 47. The membrane piercing portion 41 of the membrane splitting portion 30 disposed near the discharge area 6 pierces the ovarian membrane 101.
At this time, the muscle 100 is pressed in the direction of the transport surface 14 by the first pressing roller 53, but the first pressing roller 53 is only lowered in the direction of the transport surface 14 by its own weight, and rotates in the vertical direction. Since it can be operated (up and down), the brace 100 can be appropriately moved upward by the brace 100 when passing below the first pressing roller 53. Therefore, since an excessive pressing force does not act on the passing muscle 100, there is no possibility that the fish egg particle 102 will be crushed.
In addition, when the membrane piercing portion 41 hits the ovarian membrane 101 of the muscle 100, the muscle 100 may try to escape, but because it is pressed with a predetermined pressure by the first pressing roller 53 (the muscle 100 Each side surface is guarded by the guide wall 18.), And the membrane piercing portion 41 acts so as to surely pierce while suppressing escape of the muscle 100.
The muscle 100 is transported while the membrane piercing portion 41 penetrates the ovarian membrane 101 and is inserted into the muscle 100 and reaches the membrane cutting blade 44 of the membrane splitting portion 30. Then, the lower surface of the ovarian membrane 101 (the surface in contact with the transport surface 14) is continuously cracked (cut open) along the transport direction 200 by the film splitting blade 44. See FIGS. 5-6.

[Discharge process]
