The separating stage is one stage, or a plurality of stages are formed by arranging large-sized upper and small-sized sorting stages in the vertical direction of the frame, The moving rolls of each unit of the sorting stage are linked to one ball screw via a gear mechanism, and the gap between the corresponding fixed roll can be enlarged or shortened, and the ball screw is connected to the other gear. This invention relates to a fish sorting device that is linked to an adjustment drive device via a mechanism, and further, the adjustment drive device is electrically connected to a setting device that adjusts a predetermined gap.

<Prior art> As is well known, protein sources are extremely important for the healthy lives of the people, and fishing from the vast ocean is extremely important as a source of protein. Storage is industrially useful in many ways.

The large fishing boats used for deep-sea fishing not only transport and store fish on land, but also have facilities for freezing and predetermined processing on board.

Therefore, the obtained fish bodies are usually sorted by size before or after freezing for later processing, storage, or use. Fish sorting equipment is installed inside the fishing boat.

Generally, the fish species sorting device has a plurality of rolls arranged horizontally and installed diagonally, and fish bodies are randomly supplied from an upper chute, passing between the rotating rolls and passing through the gap between the rolls. Sorting is carried out by the falling action, and the small size that falls between the rolls and the ones that do not pass but descend on the rolls as they are 'ot□, ]01. . 1. More work 1. -3°□, 10-rules are provided to sort into a plurality of sizes.

However, when sorting fish, it is necessary to sort them by size, so 1.
In order to change the criteria for sorting depending on the size of fish using the standard sorting device, it is necessary to adjust the gap between the sorting rolls.

As a mechanism for adjusting the sorting gap, a gear mechanism or the like is used to adjust the gap at the installation position of each roll with respect to the bearing.

However, in the prior art, in order to make stepless adjustment of the gap, a handle was provided for each sorting stage or each roll, and the gap was manually adjusted.

Not only does it have some minor drawbacks, but it also has the inconvenience of requiring a high degree of skill to make adjustments according to the settings, and is not versatile.Furthermore, it takes a long time and is inefficient. Ta.

Moreover, it also has a decisive drawback in that if some rolls are forgotten to be adjusted or an unexpected sorting stage is forgotten, the sorting work cannot be carried out.

The purpose of this invention is to solve the technical problem of the handling and function of the roll gap adjustment type fish sorting device based on the above-mentioned conventional technology, and to solve the problem in the handling and function of the roll gap adjustment type fish body sorting device based on the above-mentioned conventional technology. The sorting rolls on each stage are set at the desired gap, making operation extremely easy, and also allowing quick gap adjustment, requiring little maintenance, and improving durability. The purpose of this invention is to provide an excellent fish body sorting device that is useful in the field of fish processing applications.

Means/Operation for Solving the Problems> In order to solve the above-mentioned problems, the structure of the present invention, which is summarized in the above-mentioned claims, consists of one stage from the top to the bottom of the device frame. For example, a plurality of sorting stages are provided, and a chute is provided obliquely to one or the uppermost sorting stage.

If a group of fish of a predetermined type, such as flounder, is supplied randomly,
The movable roll moves laterally with respect to the fixed roll provided on each frame of the horizontally installed multiple units of the sorting stage of the stage, through the guide provided on the frame, and therefore the movable roll moves with respect to the obliquely installed fixed roll. is moved laterally to a predetermined setting to the set sorting gap, and when adjusting the sorting gap, when a dial or the like is manually set to the predetermined setting gap on the controller, the reset setting gap for the current gap is digitally displayed. The operator learns the reset gap relative to the current gap, and the controller's arithmetic unit calculates the difference and rotates the motor of the predetermined drive device by a corresponding amount, thereby adjusting the ball connected to the gear device. As the screw rotates a predetermined amount of time, the bearing of the moving roll moves in a predetermined manner along the guide via a gear mechanism, and the gap between the moving roll and the fixed roll increases or decreases in a predetermined manner, and the fixed roll The sorting gap is set between the two sorting stages, and there is one sorting stage, or a predetermined plurality of stages from the top stage to the bottom stage, and each sorting stage is fixed in the same way as the above-mentioned top stage. The sorting gap is carried out for each horizontally installed unit of rollers and moving rolls, and the fish bodies fed from the diagonal chute above the uppermost sorting stage are passed through the vertically combined sorting stage by an oblique descent process. A technical measure has been taken in which the materials are sequentially sorted from the gaps between the tubes and transferred to the next step.

<Embodiment - Configuration> Next, one embodiment of the present invention will be described below based on the drawings.

Sub-frames 9.9.9 are horizontally installed on the front and rear frames 3, with a predetermined height difference forming the above-mentioned angle, and also serve as guides.

In each sorting stage 5.6.7, a fixed roll 10 and a moving roll 11 for fish sorting are installed together, making one unit, and a plurality of units are installed horizontally (in this embodiment, 3 units).

The fixed roll 10 and the movable roll 11 of each unit have the same set phase in the front-rear direction, but in each of the upper, middle, and lower sorting stages, as shown in FIG. It is set to come forward.

Thus, the bearing 13 of each rotation 12 of each fixed roll 10 is
As shown in the lower part of FIG. 2, each of the fixed rolls 10 is fixed to the sub-frame 9, which also serves as a guide, at a predetermined distance from each other by means such as welding. Although it is rotatable with respect to the bearing 13, it is fixed in position with respect to the device frame 3.

On the other hand, a bearing 14 that pivotally supports the rotating shaft 12 of the moving roll 11
As will be described later, as shown in FIG. 2.3, the guide/subframe 9 is engaged with the guide and subframe 9 so as to be movable left and right so as not to tilt with respect to the guide surface of the subframe. The moving roll 11 has a fish sorting gap that can be expanded or contracted with respect to the fixed roll 10.

Therefore, in FIG. 2, for convenience of illustration, the laterally movable bearings 14, 14, . . . are shown in the uppermost stage, and the fixed shafts 13, 13, .

Then, as shown in Fig. 1.2.3, each fixed roll 10
A pulley 15 is fixed to one end of the rotating shaft 12 of the moving roll 11 at the tip protruding from the bearing 13.14, and the rotating shaft is inserted into a bearing 16 fixed to the frame 3. V-belt 1 between each pulley 18 of 17
9 is each pulley 15 of each fixed roll 10 and moving roller 11
In between, zelkova is hung in a zigzag pattern.

The rotating shaft 17 is connected to a drive motor 22 edged on a bracket 21 provided on the frame 3 via a predetermined reduction gear device 20, so as to revolve around the belt 19.

Therefore, when the bearing 14 of each moving roll 11 moves horizontally, the V-belt 1 generated by the horizontal movement of the pulley 15
9 is kept in tension by tension pulleys 25 provided on three brackets 23 provided on the frame 3 via tension springs 24.

Note that 25', 25', etc. are idle booleans.

Then, as shown in FIG. 2, by engaging the belt pulley, the fixed roll 10 and the moving roll 11 are rotated in opposite directions, that is, outwardly, and are fed or dropped between them. The fish bodies are not sandwiched and forced to fall to the bottom, but the fish bodies are sorted only from the gap between the two, falling freely, and being supplied to the next sorting stage below. There is.

Therefore, as described above, the chute 8 is provided below the lowest sorting stage.

Further, although the manner in which the belt pulley rotates the fixed roll 10 and the movable roll 11 in mutually opposite directions is shown only in the middle row in FIG. 2, it is of course provided similarly in the upper and lower rows. It is about.

Therefore, in FIG. 2, for convenience of illustration, only the middle part is shown.

The horizontal movement of the bearing 14 with respect to each moving roll 11, that is, the gap between the moving roll 11 and the fixed roll 10 is as shown in FIG. A rack 28 is formed at the lower end of the rack 28, and as shown in FIG. The ball screw 30 is engaged with the worm 31 of each set span of the ball screw 30.
The @ gap can be expanded and contracted according to the normal rotation and reverse rotation of 0.

The lowermost sorting stage 7, which has a wide gap, is only shown narrowly for the sake of illustration.

The horizontal movement of the bearing 14 of the moving roll 11 is as shown in FIG. As shown in FIG. 1, a rotating shaft is pivoted back and forth at the same tilt angle as each movable roll 11 by a bearing 35 which is integrally installed under the sub-frame 9 via a bearing 35. The bevel gear 31 provided at both ends of the rotating shaft 36 engages with the bevel gear 38 provided at one end of the ball screw 30 to rotate the ball screw 30 in the forward and reverse directions. It is designed to rotate forward and backward.

Therefore, the ball screw 30 is rotated in the forward and reverse directions by a predetermined number of pulses of the pulse motor 33, and the rack 28 moves the bearing 14 back and forth through the bracket 27 via the worm 31, and the movable roll 11 relative to the fixed roll 10. The gap can be expanded or contracted.

Then, each unit at each sorting stage is
11 The gap expanding/reducing mechanism between the moving roll 11 and the fixed roll 10 is shown only in the upper sorting stage 5 in FIG. 2, but it goes without saying that it is similarly installed in the middle and lower stages 6.7. .

A controller 39 as shown in FIG. 4 is provided at a predetermined position for each sorting stage 5.6.1, and a controller 39 as shown in FIG. A digital display section 40 for the gap, and a digital display 11141 for the expansion/contraction gap to be set next are provided so as to be visible, and the operating lamps 4 of the respective red lamps are provided below.
2.43 is provided to indicate that it is operating normally, and a set dial 44 with a gap of 1 m is provided at the lower right end for new reset.
A count is displayed using the numbers set on the reset digital display 1I141, and a set operation button 45 is provided on the left side thereof.

The current gap digital display [940] is connected to the recording circuit 46 provided inside the controller, the reset digital display section 41 is connected to the setting circuit 41, and the recording circuit 46 and the setting circuit 47 are connected to the pulse motor 33. At the same time, when the reset dial 44 is electrically connected to the central processing unit 48 and the set button 45 is pressed, the central processing unit 48 calculates the difference between the recording circuit 46 and the setting circuit 47 and sets the pulse motor. 33, a pulse signal corresponding to the difference is sent to the ball screw 30 and the worm, that is, the worm 31 is given a rotational speed equal to the gap amount to be reset, and the bearing 14 of the moving roll 11 is moved left and right. The set sorting gap of the moving roll 11 with respect to the fixed roll 10 is determined, the digital count of the lower reset digital display part 41 is transferred to the digital display part of the controller 39, and the count number of the lower digital display part 41 is erased. There is.

It goes without saying that depending on the design, it is easy to combine the controllers 39 for each sorting stage shown in FIG. 4 into one.

<Embodiment - Effect> In the above configuration, the fish to be processed in the fishing boat, that is,
For example, when the processing of flatfish, etc. is determined for each size, the large, medium, and small sizes are determined in advance, and the reset dial 44 of each controller 39 is rotated according to the determination. Once decided, setting circuit 4
7, the thickness of the reset digital display section 41 is set to al.
It is digitally displayed in l units, and the lamp 43 lights up in red to indicate that the regular reset is operating normally.Then, by pressing the reset button 45, the central processing unit 48 is activated and the The gap difference between the fixed roll 10 and the moving roll 11 in the state before adjustment is calculated, and the number of pulses equal to the gap adjustment amount to be reset is applied to the pulse motor 33 (naturally). +- pulse number) is sent to the pulse motor 33.
By rotating forward and backward by a predetermined number of pulses, the rotating shaft 36 is rotated forward and backward via the gear mechanism 34, and the ball screw 30 is rotated via the bevel gear 38 at the end thereof. Therefore, each of the worms 31 moves the bearing 14 left and right along the guide of the subframe 9 of the roller 26 via the rack 28 of the bracket 27 with which each worm 31 engages, so that the rotating shaft 12 The moving roll 11 is expanded or contracted by a predetermined amount through the , and the newly adjusted sorting gap is reset.

At the same time, the digital number on the lower digital display part 41 of the controller 39 is replaced by the upper digital display part 40, and the lower part disappears.

Such sorting gap adjustment is not only performed simultaneously for each unit in one stage, but also by adjusting the corresponding sorting stage glue set dial 4 in each sorting stage 5.6.7.
The amount of movement of the movable roll 11 relative to the fixed roll 10 is automatically given in accordance with the reset amount by 4, and the sorting gap for each sorting stage is adjusted and reset.

Therefore, when a school of fish such as flounder is randomly supplied to the chute 4 on the top stage, the chute 4 slides down along the set inclination angle from the ■-shaped supply groove to the chute 4 on the top stage. Items that fall freely from the gap between the fixed roll 10 and the moving roll 11 of the size and cannot fall are
The flounder slides forward down the groove and is fed to the next stage of processing as large flounder through the chute 49 facing the tip of each roller.

The sorted flounder group that falls freely from between the fixed roll 10 and the moving roll 11 is fed between each fixed roll 10 and the moving roll 11 of the lower middle sorting stage. Those larger than the sorting gap are transported forward along the slope while being transferred between the rollers without falling through the set sorting gap between the fixed roll 10 and the moving roll 11, and are treated as medium-sized flounder as described above. It is fed to the next step via the chute 49 in a predetermined manner.

The fixed rolls 10 of each unit of the middle sorting stage are
Is the flounder falling from between the moving roll 11 and the bottom sorting stage? Fixed roll 10 and moving roll 11 of each unit
However, those larger than the set sorting gap between the two are transferred and forwarded without falling through the gap, as described above, and sent to the next process from the chute 49 as small-sized flounders. The flounder that falls from between the fixed roll 10 and the moving roll 11 of each unit and is sorted is collected at a predetermined value from a chute 8 as the smallest size flounder and is sent to the set next processing step. go.

By continuing this process in this manner, the sorting of the relevant type of flounder by size is automatically performed.

After the sorting is completed, in order to carry out the next type of fish or the next size-based sorting of the same type of fish, the fixed rolls 10 and movable rolls 11 of each unit for each sorting stage are changed as described above. The reset dial 44 of the controller 39 is reset to adjust the sorting gap according to a predetermined gap table for each size of sorting clothes (not shown), and the fixed rolls 10 of each unit of each sorting stage are newly determined in the same way as described above. What is necessary is to reset the sorting gap of the transfer@0-rule 11.

It goes without saying that the embodiments of the present invention are not limited to the above-mentioned embodiments. For example, a controller may be provided with buttons for each type of fish, or buttons for each type, and buttons for each size, and these buttons may be pressed. Various modes can be adopted to automatically control each type and size of fish by operation.

Further, the present invention can be applied not only as an internal device of a large fishing boat for deep-sea fishing, as in the above-mentioned embodiment, but also as a fixing device for a land-based Canadian nibrant.

<Effects of the Invention> As described above, according to the present invention, the device for sorting out fish such as flatfish can basically be reset by simply resetting the size of the fish to be reset, without using any manual work. The gap between the fixed roll and the moving roll is automatically adjusted, which not only has the excellent effect of accurately sorting the randomly supplied fish groups by size, but also makes the work easier. Anyone can do it without any skill, there is no operational error in the entire device, there is no breakdown, and it has excellent durability.

In addition, because there are few failures and excellent formability,
This has the excellent effect of reducing not only the initial cost but also the running cost.

In addition, since the sorting by the sorting device is performed accurately in this way, there is also the advantage in terms of processing that the next stage of processing etc. can be carried out more accurately.

Therefore, a plurality of sorting stages are provided in the vertical direction of the device, and a plurality of units are provided in the horizontal direction with fixed rolls and moving rolls of 11 nits in each sorting stage, and each moving roll is connected to a drive device. Since the screws are operated simultaneously and all at once, by providing such a system in each sorting stage, the sorting gap for each sorting stage can be set freely, so that it can be adjusted according to the size of the fish. This provides an excellent effect of providing flexibility in sorting.

Furthermore, since the drive device for the ball screw is electrically connected to the controller, an excellent effect is achieved in that the responsiveness of operation accuracy and control accuracy is extremely high.

Therefore, according to the present invention, it is possible to flexibly sort multiple species of fish by size using a single fish sorting device, and it can also be used not only for deep-sea fishing boats but also for land-based cannibals. It has the flexibility to be used. 11
