Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves transporting a paper-formed seaweed cage that has been made and dewatered by a conveyor, and lifting the paper-formed seaweed cage that has been lifted from the conveyor by a pushing-up device at the forward end of the conveyor, and grips the lifted paper-formed seaweed cage. The present invention relates to a method for positioning a sheet-formed seaweed cage when it is attached to a mounting frame of a dryer using a device.

Conventionally, when inserting the nori basket onto the paper frame of a nori paper machine, the method of positioning the nori cage has been to arrange the conveyance roller with a slight inclination in the front and back of the conveyance direction, or to tilt it in the vertical direction. A spiral convex strip is provided on the outer circumferential surface of the conveyor roller, and the seaweed cages supplied on the roller conveyor are moved diagonally to one side, and come into contact with a guide plate installed on the side to move the seaweed cages in the width direction. A widely known method is to perform positioning and to position the front end in the front-rear direction by abutting the front end against a stopper at the forward end.

However, in this method of positioning the seaweed cage, the position in the front and back direction is constant, but the position in the width direction changes depending on the length and shape of the knitting yarn ends that protrude to the outside of both edge rods of the seaweed cage. It cannot be made constant.

However, when installing the paper-formed seaweed cage that has been made into a dryer, if the positioning method in which the position in the width direction is not determined as described above is adopted, when the paper-formed seaweed cage is gripped by the cage gripping device, the This method cannot be used because there is a risk of interference between the device and the seaweed and damage to the seaweed.

In order to eliminate the drawbacks of the above-mentioned method of positioning a seaweed cage, the present invention transports the formed seaweed cage after papermaking on a conveyor, and positions it in the front-rear direction by abutting the front end against a stopper at the forward end of the conveyor. Next, the sheet-formed seaweed cage is lifted from the conveyor by a lifting device that can be raised and lowered, and when it is lifted, the edge rod on one side of the sheet-formed seaweed screen is placed on one side of the conveyor, avoiding the knitting yarn end of the screen. By lifting the formed nori seaweed cage while contacting the sloped surface of the guide member, the sheet-formed nori cage is slid in the width direction on the pushing up device to position it in the width direction, and facing the cage gripping device above the pushing up device. This is a method of accurately positioning the paper-formed seaweed cage at a predetermined position. Alternatively, the paper-formed seaweed cage is conveyed while being pulled to one side on a roller conveyor, and once the paper-formed seaweed cage is positioned in the width direction, Next, the paper-formed seaweed cage is positioned at its forward end in the front-rear direction and then in the width direction in the same manner as in the method described above, to determine the front-back and width-direction positions of the paper or seaweed cage with respect to the cage gripping device. It is an object of the present invention to provide a method for positioning a sheet-formed seaweed cage that does not damage the sheet-formed seaweed on the sheet-formed seaweed screen by a screen-gripping device by keeping the position constant at all times.
