The gripping claw 43 is pivotally supported on a support shaft 44 attached to the claw frame 35, and is biased to slide outward by a gripping spring 45 stretched between it and the allowable piece 37. In the standby position shown in the figure, the gripping claw 43 is attached to the allowable piece 37.
The tension of the return spring 40 is controlled by contacting the stopper 41 of the gripping claw 43, and the tension of the return spring 40 is controlled by the stopper 46 provided on the tip end claw 43a of the gripping claw 43 coming into contact with the claw sliding movement regulating shaft 36, thereby regulating the claw sliding movement. The member 33 and the gripping claw 43 appear to be integrated and maintain the standby state shown in FIG. It faces the pressing surface 35a with an appropriate distance H therebetween.

Reference numeral 47 denotes a pawl return member pivotally attached to the support shaft 44 so as to correspond to the above-mentioned locking piece 39. The pawl return member 47 has a push-up surface 48 and a return-preventing protrusion 49, and is biased by a spring 50. In the machine position, the open surface 49a of the return prevention protrusion 49 and the locking piece 39 of the pawl sliding restriction member 33 are in contact with each other, and the push-up surface 48 is located inside the pressing surface 35a of the pawl frame 35.

As described above, the main arm 52 is attached to the attachment arm 34, which has the claw devices 51 opposite to each other at both ends, so that the attachment arm 34 can freely move.

The tip of the main arm 52 is made to protrude from the hole 53 made in the mounting arm 34, and the bracket 54 and the main arm 52 are pivotally connected so that the main arm 52 is held between the bracket 54 provided on the mounting arm 34, and the main arm 52 is made to protrude. A stopper 55 and a leaf spring 56 are fixed to the tip of the main arm 52 by a screw 57.

58 is a distance color.

Therefore, the mounting arm 34 is movably and elastically attached to the main arm 52 until the mounting arm 34 comes into contact with the stopper 55.

As described above, the main arm 52 holds the two adjacent mounting frames 9A and 9 of the support frame 9 by one gripping means 16.
In order to insert the cages 17 alternately into the main shafts 17, the main shafts 17 are arranged so as to correspond to the vertical bars 9c of the adjacent mounting frames 9A and 9B.
Attached to 2.

The cage 17 positioned by the conveyance roller 19 is pushed up by the lifting device 2
Due to the push-up operation of step 1, the transport roller 19 is moved on the screen receiving plate 30.
The gripping means 1 waiting at the gripping position 16A after being picked up from the
In the middle of the push-up, the screen 17 on the screen receiving plate 30 hits the pressing surface 35a of the claw frame 35 and is pressed.

However, the lifting device 21 continues to rise, but the cannula 2
7 is restrained from rising by the pressing surface 35a, the core shaft 26 rises while pressing the spring 28, and the nut 29 at the top hits the rotating piece 42 and pushes it up, and the return spring 4
0, push the pawl sliding movement regulating member 33 counterclockwise in FIG. 6, and when the core shaft 26 reaches the highest end,
The state will be as shown in the figure.

That is, the locking piece 39, which was in contact with the open surface 49a of the return inhibiting protrusion 49 in the standby position by being pushed around as described above, engages with the return inhibiting protrusion 49 and controls the spring force of the return spring 40. Then, the claw sliding movement regulating member 33 is maintained in the state shown in FIG.

On the other hand, the gripping claw 43 is released from contact with the stopper 41 as the pawl sliding movement regulating member 33 is rotated as described above, so that the gripping claw 43 is pushed outward by the spring force of the gripping spring 45. During the sliding movement (rotating counterclockwise in FIG. 6), the tip claw portion 43a enters between the cage rods 17a of the cage 17 and grips the cage 17.

As a matter of course, when the gripping claw 43 rotates in this manner, the contact between the stopper 46 and the claw sliding motion regulating shaft 36 is also released, so that the claw sliding motion regulating member 33, which has been constructed as an integral structure up to now, can be removed. Direct connection with the gripping claws 43 is severed, and the gripping claws 43 can operate independently.

As described above, the gripping of the screen 17 according to the present application is first performed by slowly, as the claw sliding movement regulating member 33 rotates, by entering between the screen rods 17a in a so-called "gradual" state, and then gripping the screen 17 with the stopper 41.
When the gripping claws 43 are released from contact with each other, the entire tip claw portion 43a instantly and reliably enters with a strong force due to the spring force of the gripping spring 45 to firmly grip the cage 17.

At this time, since the cage 17 is pressed between the push-up surface 35a and the cage receiving plate 30, it is somewhat influenced by the spring force of the gripping spring 45 as it is gripped, but no complete tension is applied.

When the secure gripping is completed in this way, the push-up device 21 descends and the pressure on the screen 17 between the pressing surface 35a and the screen receiving plate 30 is released, and the gripping claws 43 are further moved by the spring force of the gripping spring 45. It slides slightly outward, applying appropriate tension to the gripped screen 17 (Fig. 7).

As is clear from the above, the cage 17 in the gripping method of the present invention
The gripping process is divided into three stages, and there is no sudden gripping that applies tension to the screen 17, so not only can the screen be gripped reliably, but the seaweed spread on the screen 17 will not be damaged. .

In this embodiment, a rotating piece 42 is provided at one end of the claw sliding movement regulating shaft 36 that is pivotally connected to the claw frame 35, and the rotating piece 42 is pushed up. The object of the present invention can also be achieved by directly pushing up the allowable piece 37.

Further, in the embodiment, the stopper 46 attached to the gripping claw 43 is made to contact the claw sliding movement regulating shaft 36, but this is not limited to the embodiment. 43 may be applied, and in short, the configuration shape is not limited as long as the condition shown in FIG. 3 is satisfied in the standby position.

After gripping the screen 17 as described above, the gripping means 16 swings as described above to insert the gripped screen 17 into the support frame 9, but the details are not directly related to the present application and will therefore be omitted.

Next, another embodiment of the gripping method of the present invention will be described with reference to FIG. 8.

In FIG. 8, 133 is a claw sliding movement regulating member, and the main arm 152
At the lower end of the sleeve 142, which is loosely fitted into

Reference numeral 140 is pressed between the mantle tube 142 and the main arm 152 and springs back, and the spring force of the return spring 140 forces the pawl sliding movement regulating member 13 downward in the drawing, and it is in the standby position as shown in FIG. As shown by the imaginary line, the gripping spring 1 comes into contact with the upper surface 134a of the mounting arm 134 attached to the lower end of the main arm 152.
The spring force of 40 is controlled.

The gripping claws 143 are pivotally connected to the tip of a claw arm 143b that is pivotally connected to the mounting arm 134, and a gripping spring 145 is stretched between the two gripping claws 143 to urge each of the gripping claws 143 to slide outward. ing.

The rear end of the gripping claw 143 is attached to the stopper 141.
In the standby position, the stopper 141 of the pawl sliding restriction member 133 pushes the rear end of the gripping pawl 143 to position the gripping pawl 143 as shown by the imaginary line in FIG. While controlling the spring force, the tip claw portion 143a faces the pressing surface 135a of the claw frame 135 at an appropriate distance.

Reference numeral 147 denotes a claw return member, which is pivotally attached to the claw frame 135 by a pivot 136A so as to correspond to the hanging claw 9D of the support frame 9 of the dryer, and its tip head is bent into a semicircular shape to form a locking portion 149. The lower end portion is a push-up surface 148.

Reference numeral 150 denotes a biasing spring for the claw return member 147, which urges the claw return member 147 to rotate clockwise in FIG. It is in contact with the locking surface 136a on the upper surface.

As a matter of course, the upper surfaces of the mounting arm 134 and the claw arm 143b in the range in which the claw return member 147 rotates are notched.

Further, the tip of the core shaft 126 of the lifting device 121 used in this embodiment is bent as shown in FIG. 8 so that it interferes with the allowable piece 13γ during the upward movement.

When the screen 17 is positioned on the conveying roller 19 as described above, the pushing up device 121 moves up, takes over the screen 17 with the screen receiving plate 130, and lifts the screen 17 with the pressing surface 135a.
As in the first embodiment, the sleeve 127 rises until it is clamped, and once it is clamped, the rise of the sleeve 127 is stopped and only the core shaft 126 continues to rise thereafter.

The core shaft 126 interferes with the allowable piece 137 during its rise, and as it rises, the claw sliding movement regulating member 133 rises to a predetermined position shown by the solid line in FIG.

When the pawl sliding movement regulating member 133 rises as described above, the gripping pawl 14 whose spring force has been restrained by the stopper 141 until now
3 is opened and rotated as shown by the solid line in FIG.

Further, when the pawl sliding restriction member 133 rises as described above, the pawl return member 147 is pulled by the biasing spring 150 and stands upright as shown by the solid line in FIG. contact in a state.

When the gripping claw 143 grips the cage 17, the push-up device 121 returns to the standby position and the push-up of the allowable piece 137 by the core shaft 126 is released, but the claw sliding restriction plate 136 comes into contact with the claw return member 147 as described above. Since it is, the return is 140
The spring force is suppressed and the claw sliding restriction member 133 remains in the pushed-up position, and the cage 17 is released from being held between the cage receiving plate 130 and the pressing surface 135a.
3 operates in three stages in the same manner as described in the first embodiment and securely grips with appropriate tension.

As described above, in the present invention, the screen 17 positioned on the conveying roller 19 is pushed up by the push-up device 21, and the screen 17 is gripped by a three-step operation in conjunction with the pushing-up operation, so that the screen 17 can be gripped with certainty. Rather, it is a useful invention that can apply an appropriate tension to the gripped screen 17 without damaging the seaweed spread on the screen 17.
