Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for horizontally aligning and discharging fish supplied on a conveyor.

[0002]

2. Description of the Related Art When storing harvested fish in a fish box for transportation or the like, the storage rate should be improved, and the fish should be aligned in the direction of the fish so that it does not take time to remove them from the box.
Need to be aligned and stored.

As described above, in order to store the fish bodies in the fish box in the same direction, it is necessary to arrange the fish bodies in the same direction on the conveyor for transferring the fish bodies to the fish box. No. 59-82042, in which fish bodies are fed from the upper end of a slanted plastic net so that the heads are first aligned and dropped;
As shown in No. 62, a vibrating conveyor is used to send it out toward the head due to the difference in the weight of the head and tail.
Like No. 584, the rotating rollers with blades are juxtaposed in the hopper, and one fish body is inserted between the blades to drop from between the rotating roller and the inner wall of the hopper. Feeding on.

The applicant of the present invention previously filed Japanese Patent Application No. 4-6913.
As proposed in No. 2, the fish bodies that are discharged in the same direction in the hopper are received on the conveyor and sent, and are further fed to the sending conveyor through the fish body aligning device composed of the impeller. There are things that can be done in multiple stages.

Further, in Japanese Patent Application No. 4-235401, fish bodies supplied from a hopper or a pumping conveyor in irregular directions are aligned on the lengthwise direction of the fish bodies through a fish body direction aligning device, and are transferred onto a transfer conveyor. It is shown that the feeding conveyor is provided with lateral partition plates at appropriate intervals on the transfer conveyor, and one or several fish bodies are laterally housed and transferred between the partition plates.

[0006]

However, in order to align and feed the fish on the transfer conveyor, a fish aligning device using a net, a vibration device, or the like, or a fish aligning device configured in multiple stages is provided. Not only does the transfer device become large in size and the device becomes complicated, but even if the fish is dropped onto the conveyor via the fish body direction alignment device, the posture will change due to the distance at the time of dropping and the conveyor speed. It was volatile and resulted in fish falling on the transfer conveyor in irregular directions, which had to be monitored and corrected manually. Even if a transfer conveyor equipped with a partition plate is used, some of them may be supplied over the partition plate depending on the amount at the time of supply and the state of the fish body, so that reliable alignment was not performed.

[0007]

As described above, the present invention provides an aligning and transferring apparatus in which partition plates are provided on a transfer conveyor at appropriate intervals and fish bodies are laterally accommodated between the partition plates.
A roller that can freely rotate is provided above the partition plate so that the fish can fall between the partition plates when the roller rotates.

Further, the fish body on the partition plate is slid off by providing an inclined portion of the conveyor in the middle of the transfer path of the transfer conveyor or at the discharge part.

Further, if necessary, it is provided with a direction correcting plate which is provided obliquely from both side edges of the transfer conveyor at an appropriate angle and whose lower edge is in contact with the roller of the partition plate.

[0009]

Therefore, the fish supplied to the transfer conveyor are stored between the partition plates and sent in the same direction, but do not fall between the partition plates when they are supplied, so that they straddle the partition plates. As the conveyor moves, the supplied fish are dropped between the partition plates by the rollers rotating toward the heavier side due to the difference in weight on both sides of the partition plate.

A fish body which is soft and hangs down on both sides of the partition plate, or which does not fall while being held on the roller across two partition plates, changes in the transfer speed when the slope portion is changed or is held. When the condition becomes slanted, the roller is rotated and stored between the partition plates.

If the direction correcting plate is provided obliquely in contact with the roller, the fish body held and sent on the roller hits the direction correcting plate and changes its posture laterally along the inclination of the direction correcting plate. At the same time, due to the movement of the conveyor, the roller rotates in the direction opposite to the feed direction due to the friction with the direction correcting plate, and the fish on the roller is moved backward and dropped from above the partition plate to between the partition plates.

[0030]

As described above, according to the present invention, since the transfer conveyor is provided with the lateral partition plates at appropriate intervals, and the roller that freely rotates in the transfer direction is provided on the upper part of the partition plate, the transfer is performed. Even if the fish supplied to the conveyor do not enter between the partition plates and there is a fish that is sent over the partition plates, the rollers freely rotate on the heavy side of the fish while the transfer conveyor is moving, Can be slid and dropped between the partition plates to align the directions.

Further, by providing an inclined portion in the middle of the transfer path of the transfer conveyor or on the discharge side, even if there is a fish body which is not dropped from the partition plate and is held on the roller during the movement of the transfer conveyor, When moving to the sloping part, the moving distance of the roller on the top of the partition plate changes and the moving speed changes, the inertia surely drops the fish body, and the tilt changes the direction of the partition plate to make the fish body slippery It can be dropped between the boards, and it is stored horizontally between the partition boards.

Therefore, it is not necessary to completely align the directions of the fish bodies and supply the fish to the transfer conveyor, and the fish can be housed between the partition plates during the transfer of the transfer conveyor to align the directions.
Before supplying to the transfer conveyor, a complicated aligning device is installed to match the direction of the fish with the direction of the partition plate, and the number of manual corrections on the transfer conveyor is eliminated, simplifying the supply device to the transfer conveyor. Therefore, the fish bodies on the transfer conveyor can be reliably housed between the partition plates, and the fish bodies can be favorably aligned.

Further, since the direction correcting plate is provided in an oblique direction from both sides of the transfer conveyor at an appropriate angle and the lower edge of the direction correcting plate is brought into contact with the roller, the fish body held on the roller and fed is While changing the posture along the direction correction plate, the roller automatically rotates in the opposite direction to the feeding direction as the conveyor moves, so the fish on the roller can be reliably dropped between the partition plates. The effect that the fish bodies can be effectively aligned is obtained.
