DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pair of gripping arms having gripping claws and disposed oppositely so as to move downwardly and outwardly, a locking means for locking the movement of the gripping arms, and and a release means for detecting the lock and releasing the lock of the locking means, and when the gripping arm slides, the gripping claws enter between the birch materials of the nori sheet and grip the nori sheet under tension. This is related to improvements.

Hitherto, as this type of laver gripping device, there has been known a device in which a pair of left and right gripping arms are connected to a rotating member of a locking means by a link, so that both gripping arms always move and return at the same time. However, in such a device, if one gripping arm hits the nori before the other and the disturbance is stopped, the other gripping arm still hits the nori. I made a bale,
Despite this, there was a drawback that the movement of the gripping arm was stopped, resulting in a mistake in gripping the nori tube.

In addition, in the device described above, since the pair of gripping arms are connected to the rotating member by a link, it is not possible to move both gripping arms symmetrically, leading to errors in gripping the seaweed. It was easy. Therefore, in view of the above drawbacks of the conventional device, it is an object of the present invention to eliminate this problem, and it is possible to make the pair of left and right gripping arms symmetrically vibrate, and moreover, it is possible to move both gripping arms to the seaweed container. It is an object of the present invention to provide a laver gripping device that can reliably shake the seaweed until the seaweed is lifted.

Next, embodiments of the present invention will be described in detail based on the drawings.

Next, 41 is a lower finger plate for supporting the lower side of the end of the seaweed tube 8, and a shaft 42 rotatably bridged over the side plates 9a and 9b of the frame body 9.
The left and right sides are struggling against each other. This lower plate 41 is the back plate 9c
The engaging arm 45 fixed to the shaft 42 is biased counterclockwise in FIG. 3 by a spring 44 stretched between the shaft 42 and the stopper 46 shielded from the side plate 9a. At this time, the tip of the lower fingerboard 41 is located to the right in FIG. 3 of the gripping position of the nori 8 by the gripping claws 19, 20, 19e, and 20e, at approximately the same height as the parentheses. It is designed to be. Reference numeral 47 denotes an operating plate that receives the roller 45a of the engaging arm 45 and holds the lower fingerboard 41 swinging clockwise against the spring 44 when the nori gripping device A is moved to the chopstick gripping position. , when the nori tube gripping device A is raised to a certain extent, this lower fingerboard 4

When gripping the nori sheet holding device A, the moving position of the nori sheet gripping device A is regulated by bringing it into contact with 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 chopsticks A is moved downward toward the nori chopsticks 8 at the nori gripping position by the swinging of the support arms 1 and la, the roller 45a of the engaging arm 45 first engages 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 cover detection lever 36 comes into contact with the upper 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.
Normally, the gripping claws 19, 19e on the side closer to the center of the disturbance of the nori pipes 6, 16e enter between the bamboo pieces 8a of the nori tube 8 and grip the nori pipe 8 under tension. In this case, the gripping arm 16
, 16e is due to 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 to prevent damage to the sand seaweed when gripping the seaweed 8 to which the seaweed is attached (hereinafter referred to as seaweed attachment). Further, even if the positive movement of one gripping arm is stopped midway through the movement of the gripping arms 16, 16e, the positive movement of the other gripping arm can be rotated to a position where the circular drum 31 is regulated by the stopper 38. Because it is, it will be done afterwards. 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 16e can be pressed against the seaweed tube 8, and mistakes in gripping the seaweed tube 8 can be prevented. Further, after the base motion of the gripping arms 16, 16e hits the seaweed cover 8 and is stopped, the elements 34a, 34ae are pulled by the springs 25, 25e to absorb the sag 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 sand seaweed and damage the sand seaweed. Thereafter, the plate 49 of the seaweed gripping device A is pressed against the seaweed 8, and the gripping device A is raised by the swinging of the support arms 1, la, and the gripping claws 19, 19e also lifts the end of the gripped seaweed 8.

The above is due to the movement of the gripping arms 16, 16e, and the gripping claws 19,1
This is the operation when the gripping claw 9e gets between the seaweed material 8a of the seaweed tube 8, and at least one of the gripping claws 19, 19e comes into contact with the seaweed material 8a of the seaweed tube 8 or the knitting yarn 8b, 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,
This will be explained assuming that a gripping error has occurred. That is, when the seaweed holding device A is pressed against the seaweed 8 and then raised,
As the gripping arms 16 and 16e move upward, the spring 18
, 18e further swings, and finally the gripping claws 20, 20e on the side far from the center of rope movement enter between the bamboo pieces 8a of the nori 8, as shown in FIG. 5, and grip the nori 8 under tension. . In this case, the gripping claws 19, 19e and the gripping claws 20, 20e
Since the gripping arms 16 and 16e are displaced to some extent in the direction perpendicular to the sliding surfaces, the gripping claws 19719e on the side closer to the center of the gripping movement grip the striped thread 8b of the nori chopsticks 8, as shown in FIG.
When the knitting yarn 8b hits the knitting yarn 8b, the gripping claws 20, 20e on the side far from the commotion center will not hit the knitting yarn 8b and cause a gripping error. Next, after gripping the nori sheet 8 as described above, the nori sheet gripping device A is raised toward the chopstick release position by the swinging of the supporting 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 sheet 8 held by the gripping arms 16 and 16e, supporting the nori sheet 8 in a cantilevered state. After that, Shido 4's return arm 39 pin 401
This engagement causes the circular drum 31 to rotate against the elasticity of the springs 18, 18e, and finally the engagement step portion 32 of the cam 30
The locking piece 37 engages with. As a result, the gripping arms 16,1
6e is returned to the standby position and releases the grip on the nori 8, but the nori 8 still holds the gripping arms 16, 16.
e and the lower fingerboard 41 in a cantilevered manner. Then, when the nori tube gripping device A is moved to the tube opening position, the engaging arm 45. The roller 45a engages with the operating plate 48, and the lower finger plate 41 is swung clockwise in FIG. 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 tubes one by one. FIG. 7 shows a different embodiment of the present application, in which two levers 53 and 54 are provided on the frame 9V as rotating members, and which rotate synchronously and in opposite directions by meshing gears 51 and 52. The other lever 54 is connected to the gripping arm m6V of the gripping arm m6V by links 55 and 56 as connecting members to the other gripping arm 16eV, and the sliding movement of the gripping arms 16V and 16eV due to the springs 18V and 18eV is restricted. In this case, the links 55 and 56 are connected through the elongated holes 57 and 58 so that the gripping arms 16V and 16eV move reliably until they touch the seaweed.

Note that the locking means is omitted in this embodiment.Furthermore, blanks may be used in place of the links 55 and 56 in this embodiment.FIG. 8 shows that when a blank 34W is used as the connecting member, The raw 34W when the whisker movement of the arm 16W is caught
Attach a spring piece 59 to the frame 9W to prevent it from sagging.
This spring piece 59 is also adapted to lift up the rope 34W, and parts that are the same or equivalent to those in the first embodiment are given the same reference numerals and the letter W, and redundant explanation will be omitted.

Although the above embodiment shows the case where the nori pipe is held in a cantilevered state, it is also possible to hold the nori tube in a cantilevered manner, but it is also possible to do so when the nori tube is held in a cantilevered state.In this case, for example, the lower fingerboard may be omitted. Instead, two or more pairs of gripping arms may be provided.

Further, the means for moving the nori chopstick gripping device may be any suitable means, and is not limited to the above embodiment. As described above, in the present invention, the movements of the pair of gripping arms are performed in synchronization, so that when gripping a piece of seaweed, both gripping arms can be simultaneously released. This has the advantage of being able to grip the nori at the correct gripping position and reducing gripping errors.

In addition, even if both gripping arms are made to move in synchronization as described above, when the locking piece of the spreading member is released, each gripping arm moves in unison with the other gripping arm. Since the commotion is made to occur regardless of the amount of turbulence of the gripping arms, even if both gripping arms do not touch the nori at the same time when gripping the nori, both gripping arms will remain locked until they come into contact with the nori. It has the effect of being able to grip the yellow seaweed.
