Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to a device for removing a locking pin from a rope for suspension of cultured scallops with a locking pin after use for the purpose of reuse.

(Prior Art) In cultivating scallops, the term "ear ears" is used to
As shown in the figure, locking pins are usually attached to a rope of 10 to 20 m at intervals of about 15 cm, and young scallops are lowered on the locking pins and suspended in the sea for aquaculture.

The rope will be reused after the aquaculture is finished and the adult shellfish are collected, but the remaining locking pins must be removed at that time. Conventionally, the work for removing the locking pin has been performed manually.

It is common to remove about 200,000 to 500,000 locking pins per fisherman, but the labor and time required for this are extremely large.

In order to deal with this, a locking pin removing device has been devised, but the locking pin cannot be completely removed, and the locking pin is often cut and remains. The work performance was not good.

(Problems to be Solved by the Invention) Problems to be solved by the present invention include a locking pin that has a simple structure, is easy to handle and adjust, and can perform the locking pin removal work quickly and reliably. An object of the present invention is to provide a locking pin removing device for an attached rope.

(Means for Solving the Problems) The gist of the present invention which has solved the above problems is as follows: 1) A plurality of circles of gears or the like are provided at a lower position of a rope with a locking pin that applies a predetermined tension and conveys in the longitudinal direction. Two parallel rotary shafts with plate-shaped rotating bodies attached at predetermined intervals are arranged so as to form a right angle with the conveying direction of the rope with locking pins, and a motor for rotating the rotary shafts is provided. The mechanism is such that the outer circumferences of the disk-shaped rotating bodies of the rotating shaft intersect and rotate, and it is detected that the locking pin of the rope with the same locking pin is caught at the intersection of the outer circumferences of the same disk-shaped rotating body. A locking pin removing device for a rope with a locking pin, characterized in that it is provided with a detecting means, and a temporary stopping means for temporarily stopping the rotation of the motor for a predetermined time in response to a bite detection signal of the detecting means.

2) At least one of the two rotary shafts is allowed to be finely movable in the direction perpendicular to the conveying direction of the rope with the locking pin,
2. A locking pin removing device for a rope with a locking pin according to claim 1, wherein a sensor for detecting a slight movement of the rotary shaft is provided, and the detection signal is constituted by the detection signal as a biting detection signal.

3) A scraper for removing inclusions between the disc-shaped rotating bodies is attached near the outer circumference of the disc-shaped rotating bodies, and the rope with the locking pin is locked according to claim 1 or 2. Pin remover.

(Operation) In the locking pin removing device of the present invention, the lower part of the locking pin is temporarily sandwiched at the portion where the outer peripheries of the disk-shaped rotating bodies provided below the rope with the locking pin conveyed at a constant speed intersect. Hold and
During that time, the rope with the locking pin is transported,
The locking pin can be pulled out from the rope.

When the lower part of the locking pin of the rope with a locking pin that is transported at a constant speed bites into the intersection of the outer circumferences of the disk-shaped rotating body, the detection means operates, and the temporary stop means is activated by the biting detection signal. When the motor is actuated and the rotation of the motor is stopped, the rotary shaft of the disk-shaped rotating body is stopped for a predetermined time and held below the locking pin. During that time, the rope with the locking pin is moving in the longitudinal direction, so that the lower part of the locking pin is fixed and the rope with the locking pin is pulled, and the locking pin is removed from the rope. be able to.

When the locking pin comes off, the disk-shaped rotary body starts to rotate again and prepares for the next locking pin. After that, the same operation is repeated.

Since the length of the locking pin is almost constant and the conveying speed of the rope with the locking pin is also constant, the length of the suspension time of the rotating shaft of the disk-shaped rotating body should be fixed by a timer. Thus, the work for removing the locking pin can be automatically performed.

The intersection of the outer circumferences of the disk-shaped rotating body has a certain range, and if the rotation axis of the disk-shaped rotating body is temporarily stopped while the locking pin is engaged within this range. Since it is good, even if there is some error in the timing of the temporary stop, the work for removing the locking pin can be performed without mistake. In addition, it is easy to adjust the timing of the temporary stop.

The lower part of the locking pin is bite and held at the intersection of the outer circumferences of the disk-shaped rotating body, so the holding state is soft and reliable, and removal work can be done without cutting the locking pin. It can be carried out.

As the detecting means of the present invention, there is also one in which at least one of the two rotary shafts is allowed to be finely movable, and the fine motion of the rotary shafts is detected by a sensor to temporarily stop the rotation of the rotary shafts. When the lower part of the locking pin bites at the intersection of the outer peripheries of the disk-shaped rotary bodies attached to the two rotary shafts, the disk-shaped rotary body makes a fine movement, and the fine movement of the rotary shaft corresponding to the same is performed. The rotation of the rotary shaft is temporarily stopped by sensing with a sensor, and the lower part of the locking pin is sandwiched and temporarily held.

In the locking pin removing device of the rope with the locking pin of the present invention, a scraper is provided between the disk-shaped rotating bodies to remove inclusions such as locking pins. This is to prevent the locking pin after being pulled out from interposing between the disk-shaped rotating bodies and causing a trouble or the like.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

It is explanatory drawing which shows the use condition of a rope with a locking pin.

In the present embodiment, two parallel rotating shafts 4, each having a plurality of gears 2, 3 attached at predetermined intervals, are provided below the rope 1 with a locking pin for imparting a predetermined tension to convey the rope 1 in the longitudinal direction. 5 is arranged so as to form a right angle with the conveying direction of the rope 1 with a locking pin, and the outer circumferences of the gears 2 and 3 of the respective rotation shafts 4 and 5 are rotated so that they rotate. The rotating shafts 4 and 5 are each driven by a motor 6.

When the locking pin 7 of the rope 1 with the locking pin engages with the intersection 8 between the outer circumferences of the gears 2 and 3, the rotary shaft 4 moves slightly together with the gear 2. The fine movement of the rotary shaft 4 is expanded by the lever 9, and the rotation of the motor 6 is temporarily stopped for a predetermined period of time by being detected by the sensor 10 to temporarily stop the rotary shafts 4,5 and the gears 2, 3.
