When gripping the nori sheet 8, the movement position of the nori sheet gripping device A is regulated by pressing against the upper surface of the nori sheet 8.

The present embodiment is constructed as described above, and its effects will be explained next.

When the nori gripping device A is moved downward toward the nori gripping position 8 by the swinging of the supporting arms 1 and la, the roller 45a of the engaging arm 45 first engages with the actuating plate 47 and the lower finger Board 41
is swung clockwise in FIG. 3 and moved to a position where it does not interfere with the seaweed 8 to be gripped.

Thereafter, the chopstick detection lever 36 comes into contact with the top surface of the end of the seaweed cover 8 and is rotated slightly clockwise in FIG. . Therefore, the pair of gripping arms 16, 16e are connected to the spring 1.
8 and 18e, the circular drum 31 is rotated clockwise in FIG.
Usually, the gripping claws 19, 19e on the side closer to the center of the commotion, as shown in FIG. In this case, the gripping arm 16
, 16e is caused by the element 34 accompanying the rotation of the circular drum 31.
Since the amount of unwinding of a and 34ae is the same, the unwinding is performed in perfect synchronization. Therefore, the gripping claws 19, 19e of the left and right gripping arms 16, 16e can be inserted into the seaweed shell 8 at the same time, and the horizontal movement of the seaweed shell 8 when the gripping claws 19, 19e are inserted can be prevented. It is possible to stabilize the gripping position of the seaweed, and when gripping the seaweed 8 to which the seaweed is attached (hereinafter referred to as seaweed attachment), damage to the seaweed can be prevented. Furthermore, even if one of the gripping arms is stopped midway through the movement of the gripping arms 16 and 16e, the other gripping arm can be rotated to a position where the circular drum 31 is regulated by the stopper 38. It will be carried out thereafter. Therefore, even if the distances of the gripping arms 16, 16e to the seaweed cover 8 are different, both gripping arms 16,
The gripping claws 19, 19e of the nori sheet 16e can be pressed against the seaweed sheet 8, and mistakes in gripping the seaweed sheet 8 can be prevented. In addition, after the swinging of the gripping arms 16, 16e hits the seaweed cover 8 and is stopped, the elements 34a, 34ae are also pulled by the springs 25, 25e to absorb the twisting and do not sag downward. Therefore, when grasping the seaweed charge, the elements 34a, 34a
It is possible to eliminate the possibility that e may drip onto the seaweed and damage the seaweed. Thereafter, the plate 49 of the nori tube gripping device A is pressed against the nori tube 8, and then the nori tube gripping device A is raised by the swinging of the supporting arms 1, la, and the gripping claws 19, At 19e, the end of the nori chopsticks 8 held tightly is raised.

The above is due to the transfer of the gripping arms 16, 16e to the gripping claws 19, 1.
This is an operation when the 9e gets between the bamboo pieces 8a of the seaweed piece 8, but ``at least one of the gripping claws 19, 19e hits the piece of seaweed piece 8a or the striped thread 8b of the seaweed piece 8, causing a gripping error. In this case, the gripping of the seaweed 8 is carried out as follows, but if the gripping claws 19, 19e of both gripping arms 16, 16e
This will be explained assuming that a gripping error has occurred. That is, when the nori tube gripping device A is pressed against the nori pipe 8 and then raised,
As the gripping arms 16 and 16e move upward, the spring 18
, 18e, and the gripping claws 20, 20e, which are far from the center of the key movement, finally reach the nori cover 8 as shown in FIG.
It enters between the bamboo leaves 8a and grips the seaweed 8 under tension. In this case, the gripping claws 19, 19e and the gripping claws 20, 20e are displaced to some extent in a direction perpendicular to the turbulent surfaces of the gripping arms 16, 16e, so as shown in FIG. When the gripping claws 19, 19e on the sides hit the knitting yarn 8b of the seaweed fabric 8 and cause a gripping error, the gripping nails 20, 20e on the side far from the concentration center will not hit the knitting yarn 8b and cause a gripping error. Next, after gripping the nori roll 8 as described above, the nori gripping device A is raised toward the open position by swinging of the support arms 1, la.

Then, as the seaweed gripping device A rises, one end of the seaweed grip 8 is first raised, and then the rocking hold of the lower fingerboard 41 by the operating plate 47 is released, and the lower fingerboard 41 is moved by the spring 4.
4, it is swung counterclockwise in FIG. As a result, the tip of the lower fingerboard 41 supports the lower surface of the nori tube 8 held by the gripping arms 16 and 16e, supporting the nori tube 8 in a cantilevered state. Thereafter, the return arm 39 of the support shaft 4 engages with the pin 40 to rotate the circular drum 31 against the elasticity of the springs 18 and 18e, and finally the locking piece 37 is attached to the engagement step 32 of the cam 30. is engaged. As a result, the gripping arms 16, 16
e is returned to the standby position and releases the grip on the nori 8, but the nori 8 still holds the gripping arms 16, 16e.
and the lower fingerboard 41 in a cantilevered manner.
When the seaweed gripping device A is moved to the tube opening position, the roller 45a of the engaging arm 45 engages with the operating plate 48, and the lower finger plate 41 is swung clockwise in FIG. The seaweed 8 is supplied falling onto a roller conveyor 50.
Thereafter, the seaweed gripping device A is again moved to the tube gripping position, and the above operations are repeated to automatically feed the seaweed 8 one sheet at a time. In the above embodiment, the case is shown in which the device is applied to a device for gripping the seaweed sheet 8 in a cantilevered state, but it is also possible to implement it in a device that grips the seaweed sheet 8 in a state in which it is held at both ends. In this case, for example, the lower fingerboard 41 may be omitted and two or more pairs of gripping arms may be provided instead.

Further, the reciprocating movement of the nori tube gripping device A may be performed by an appropriate device. Further, the present application is not limited to the configuration of the locking means and the releasing means, and any structure that achieves the purpose is sufficient.

Furthermore, the shapes of the gripping arms and gripping claws are not limited, and can be changed as appropriate. For example, changing the gripping arm to two arms and attaching a gripping claw to each arm, or changing the gripping claws to U. You may change it to a letter-shaped wire. As described above, in the present invention, the gripping arm is provided with two gripping claws at different distances from the center of commotion, and when a commotion occurs, the gripping claw on the side closer to the center of motion is replaced by the gripping claw on the far side. Since they are attached at different phases in the commotion direction so that they are more advanced, even if the gripping claw on the side closer to the commotion center of the gripping arm makes a gripping error when gripping the nori, the gripping claw on the side far from the commotion center will be able to grasp it. The claws can grip the nori sheet, which has the effect of reliably gripping the nori sheet.

In addition, since the above two gripping claws were installed by being displaced in a direction perpendicular to the coagulation surface of the gripping arm, the gripping claw on the side of the gripping arm closer to the center of the gutter hit the knitting yarn of the nori chopsticks, causing a gripping error. In this case, it is possible to prevent the gripping claws on the side far from the center of the commotion from hitting the seaweed yellow knitting yarn again, which has the advantage of reducing the possibility of gripping errors.
