Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides the following features:
The present invention relates to an automatic fresh fish sorting machine that sorts the size of fish that slides down on it, and particularly relates to an opening/closing device for adjusting the interval between rotating rollers.

[Prior Art] A conventional sorting roller spacing adjustment device for this type of automatic fresh fish sorting machine is, for example, the one previously filed by the present applicant and described in Japanese Patent Publication No. 39037/1983. There is something.

In this case, the bearing case of the rotating roller is fixed to a sliding block, a bolt passing through a sliding groove is screwed into the lower side of the sliding block, and a circular hole is provided on the side of the sliding block. , an externally threaded sleeve and an internally threaded sleeve are connected and fitted into this, the external threaded sleeve is provided with hexagonal holes, and a hexagonal shaft having a handle is fitted into each hexagonal hole.

[Problems to be Solved by the Invention] However, in the above conventional sorting roller spacing adjustment device of the automatic fresh fish sorting machine, the outer threaded portion of the outer threaded sleeve is screwed into the inner threaded portion of the adjacent inner threaded sleeve. The structure was such that a large number of internal and external threaded sleeves were connected alternately, and a hexagonal shaft was passed through the hexagonal hole of each connected external threaded sleeve. Pull out the hexagonal shaft to the hexagonal hole of the external threaded sleeve that screws into the internal threaded sleeve of the sliding block that supports the rotating roller you are trying to rotate, and hold the threaded part of the external threaded sleeve that has come off the hexagonal shaft with pliers. ,
The sliding block was adjusted by turning a hexagonal shaft, and the structure was such that a spanner could not be used on the externally threaded sleeve. In this case, since the tip of the hexagonal shaft is not visible, the operator must be highly skilled in order to align the tip with the desired hexagonal hole.
This work requires two people, one for positioning and the other for rotating the sleeve, which poses a problem in that the adjustment work requires time and many hands.

In addition, since the spacing between adjacent sliding blocks is narrow and the adjustment screw cannot be used to widen the opening/closing distance, when sorting the size of landed fish, it is necessary to use screws with the length of the roller spacing for small fish. There was a problem in that it was necessary to manufacture screws of about 5 different lengths, such as screws with the length of the roller spacing for medium-sized fish and screws with the length of the roller spacing for large fish. .

Furthermore, since the amount of movement of the sliding block relative to the amount of rotation of the externally threaded sleeve is determined by the pitch of the internal and external threaded parts that screw together, there is the problem that fine adjustment of the roller spacing cannot be made precisely. Ta.

The present invention has been made in view of such conventional problems, and it is possible to finely adjust the spacing between the rollers while penetrating the square shaft, and by opening and closing the sliding block in two stages, the above-mentioned problem can be solved. The purpose is to solve problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a fresh fish automatic system that sorts the size of fish that slides over the gaps between an appropriate number of rotating rollers installed at an angle on the machine body. In the sorting machine, bearings that rotatably support at least one end of the rotating rollers are individually fixed to an appropriate number of sliding blocks attached to the body so as to be movable in a direction intersecting the axial direction of the rotating rollers. Each sliding block is provided with a screw hole extending in the above-mentioned cross direction with a right-hand thread on one side and a left-hand thread on the other side, and flanges are provided at the outer ends of both sides of the screw hole. A first threaded sleeve and a second threaded sleeve each having an internal thread wound in the same direction on the inside thereof are screwed together, and a square hole passes through the shaft center portion of the internal thread of both threaded sleeves. The square hole sleeves are screwed together to connect adjacent sliding blocks, and square shafts with handles are fitted into the square holes of all the square hole sleeves, and the first screw sleeve and the second screw sleeve are connected.

In addition, 40 shown in FIG. 6 is a conveyor device that supplies landed fish to this device, and the supply section 4
The fish supplied at No. 1 is transported in the direction of arrow A and introduced into this device.

The apparatus having the above configuration is assembled, for example, in the following order.

First, place the required number of sliding blocks 9 on a suitable table, and tighten the third external screw 25 of the square hole sleeve 24.
from the flange 20a side of the first threaded sleeve 20 to the third internal thread 18, and also the fourth external thread 2
6 to the fourth internal thread 19 from the flange 22a side of the second threaded sleeve 22, turn the square hole sleeve 24 and screw the shaft portions 24b, 24c on both sides into each threaded sleeve 20, 22, and then screw both threaded sleeves together. The flanges 20a, 22a of 20, 22 are brought close together so as to be aligned with the central flange 24a.

Next, turn each threaded sleeve 20 to cut out the notches 20 provided in the flanges 20a and 22a.
b, 22b to the flange 24a of the square hole sleeve 24
Align with the long grooves 29 provided in the section, wrap the band 28b around both flanges 20a and 22a while aligning the teeth 28a with the six long grooves 29, and tie the connecting pieces at both ends to fix the toothed ring 28. .

After that, the two sliding blocks 9 are placed on the slide rail 10, and the first external thread 21 of the first threaded sleeve 20 of the previously assembled sleeve assembly is screwed into the first external thread 21 of the first threaded sleeve 20 of the previously assembled sleeve assembly. At the same time, the second external thread 23 of the second threaded sleeve 22 is screwed into the second internal thread 17 of the other sliding block 9, thereby connecting the two sliding blocks. Connect 9. In this case, a short hexagonal bar may be inserted into the hexagonal hole of the square-hole sleeve 24 and used as an assembly tool to rotate the sleeve assembly.

This connection operation is repeated to connect the number of sliding blocks 9 corresponding to the rotating rollers 5 to be used.
In this case, the gap between adjacent sliding blocks 9 is temporarily set to a predetermined value. In this embodiment, the first external thread 21 provided on the outer peripheral surface of the first threaded sleeve 20 is a right-handed thread, and the second external thread 23 provided on the outer peripheral surface of the second threaded sleeve 22 is a left-handed thread. Therefore, by turning the sleeve assembly, the threaded sleeves 20, 22 on both sides can be threaded into the adjacent sliding blocks 9 simultaneously and easily.

After all the sliding blocks 9 are connected in this way, the guide protrusions 12 provided on the lower surface of each sliding block 9 are engaged with the guide holes 11, respectively. and,
Fixing bolts 13 are screwed together from below, and each sliding block 9 is temporarily tightened through washers 14.

Subsequently, the hexagonal shaft 30 is inserted into the sliding block group from the outside of the tilting table 3, passes through all the square hole sleeves 22, and the hexagonal shaft 30 is attached to the tilting table 3. Then, turn the handle 33 left and right to loosen all square hole sleeves 24 and threaded sleeves 20, 22, and then tighten the fixing bolts 13 to fully tighten each sliding block 9.

Next, the bearing part 4 is fitted onto the support shaft part 8 of each sliding block 9, and the rotating roller 5 is assembled by spanning between the bearing parts 4, which form a pair in the inclination direction. and,
A gauge is inserted between adjacent rotating rollers 5 to measure the gap between the rollers.

As a result of the measurement, if the clearance between the rollers is not within the predetermined range, the sliding block 9 to be moved
Slightly loosen the fixing bolt 13, remove the toothed ring 28, and remove one threaded sleeve 20 (or 22).
Finely adjust the gap by turning the flange 20a (or 22a) by hand or with a spanner with a pin. After the roller gaps of all the rotating rollers 5 have been adjusted, the toothed ring 28 is attached again to fix both the threaded sleeves 20 and 22.

In this case, the first and second internal and external screws 16, 21
And the pitch of 17, 23 is set to 16 threads/1 inch, and the third and fourth internal and external screws 18, 25
If the pitches of the rollers 19 and 26 are, for example, 22 threads/1 inch, the difference in pitch is 0.43 mm, so the gap between the rollers can be adjusted by 0.43 mm with one rotation of the square hole sleeve 24. Therefore, by rotating the square hole sleeve 20 by 1/6 turn, the roller gap can be adjusted as fine as 0.07 mm.

On the other hand, the opening/closing operations of the first stage and the second stage, which widen and close the interval between the rotating rollers 5, are performed as follows.

The opening/closing operation of the first stage is performed when small fish are to be sorted, and the first threaded sleeve 20, second threaded sleeve 22, and square hole sleeve 24 are integrated in the rotational direction by the toothed ring 28. In this state, hold the handle 33 and rotate the hexagonal shaft 30. Both threaded sleeves 20, 22 and the square hole sleeve 24 are integrated in the rotational direction by the teeth 28a of the toothed ring 28, but can be moved relative to each other in the axial direction. Since the first threaded sleeve 20 has a right-handed thread and the second threaded sleeve 22 has a left-handed thread, when the hexagonal shaft 30 is rotated one turn to the right, the pitch of the first internal and external threads 16 and 21 changes. Both threaded sleeves 20, 22 are separated by a length equal to the pitch of the second inner and outer threads 17, 23, and the distance between adjacent rotary rollers 5 is widened by the amount of movement.

The opening/closing operation of the second stage is performed when large fish are to be selected. , 22 are fixed to each sliding block 9 with a locking screw 34, and with the toothed ring 28 removed, the hexagonal shaft 30 is rotated, for example, one turn to the right using the handle 33. Then, due to the rotation of the square hole sleeve 24, the first and second screw sleeves 20, 22 are relatively pushed open, and the third screw sleeve 24 is rotated.
Both threaded sleeves 20 and 22 are further separated by a length equal to the pitch of the fourth inner and outer threads 18 and 25 plus the pitch of the fourth inner and outer threads 19 and 26, and the distance between adjacent rotating rollers 5 becomes wider by the amount of movement. Become.

The opening and closing operations of the first stage and second stage described above can be performed simultaneously for all rotating rollers 5. Furthermore, when the hexagonal shaft 30 is rotated to the left, the distance between adjacent rotary rollers 5 becomes narrower, contrary to what has been described above.

By opening and closing the first or second stage in this way, it is possible to sort out a wide range of fish from large to small fish, and by making the above-mentioned fine adjustments, Therefore, it is possible to accurately sort out the size of fish of the same species. Moreover, the fine adjustment of the roller gap and the opening/closing operations described above can be easily performed by a single operator of the apparatus.

In the above embodiment, both ends of the rotating roller 5 are supported on the inclined table 3 via the bearing part 4 and the sliding block 9, but the present invention is not limited to this. The bearing part 4
It may be supported by the sliding block 9.

In addition, in the above embodiment, an example was explained in which a hexagonal shaft was used as the square shaft, but of course, a square shaft, a triangular shaft, an octagonal shaft, and other polygonal shafts may be used.
It is also possible to employ a shaft having a round shaft provided with a flat surface extending in the axial direction. Further, although the first and third internal and external threads are right-handed threads and the second and fourth internal and external threads are left-handed threads, it is of course possible to use an opposite thread structure.

[Effects of the Invention] As explained above, according to the present invention, the bearing portion that supports one end of the rotating roller is fixed to a sliding block movably attached to the machine body, and Screw the first and second threaded sleeves into the threaded holes having right-hand and left-hand threads, thread the square-hole sleeves into the adjacent threaded sleeves, connect the adjacent sliding blocks, and connect all the square-hole sleeves. A square shaft is inserted into the square hole, and the spacing between the rotating rollers can be adjusted in multiple stages according to the attachment and detachment of the toothed ring. Therefore, by rotating the first or second threaded sleeve with the toothed ring removed, the interval between the rotating rollers can be precisely and easily fine-adjusted. , opening and closing the intervals between all rotating rollers simultaneously and equally over a wide range by the first stage opening/closing operation of rotating the square shaft with the second threaded sleeve and the square hole sleeve integrated in the rotational direction; Furthermore, by removing the toothed ring and rotating the square shaft with the first and second threaded sleeves fixed to the sliding block, the second stage opening/closing operation widens the spacing between all the rotating rollers. Can be opened and closed at the same time.

Therefore, there is no need to prepare a large number of screw shafts of different lengths in advance, as is the case with conventional methods, and this device alone has the advantage of being able to sort fish by size over a wide range from small to large fish. is obtained.
Moreover, there is no need to perform the troublesome work of putting in and taking out the square shaft like in conventional devices, and by appropriately rotating the threaded sleeve or the square shaft, fine adjustment of the spacing between rotating rollers and opening/closing operations can be easily performed. Moreover, it is possible to provide an apparatus that can perform the process with high precision.
