A horizontal rod 34, which forms an engaging portion 34b so as to swing slightly together, is fixed to the center of a support shaft 36 that is pivoted to a bearing plate 35 fixed to the lower side of the tip of the bracket 113a. Hooks 2 are hung on both sides of the cylindrical body 200 at both ends of the support shaft 36 to which the rod 34 is fixed.
Push-down arms 3γ and 37 are respectively fixedly attached to the upper portions of the bent portions 23a and 23a of No. 3 at a predetermined interval, and the push-down rods 3
7, 37 and the horizontal rod 34 are held at the standby position shown in the figure, with a stopper 34a provided at the upper part of the horizontal rod 34 abutting against a bearing plate 35 due to their own weight.

Further, above the seaweed cage 11 lifted from the roller conveyor 3 at the forward end position by the above-mentioned lifting device 12, a cage gripping device 40 is disposed facing the roller conveyor 3 at an appropriate distance. Although the screen gripping device 40 is configured to automatically insert the gripped seaweed screen into a support frame of a dryer (not shown), only the screen gripping device 40 directly related to the present invention will be described below.

40 is a roller conveyor 3 as shown in FIGS. 1 and 2.
At the lower end of the vertically supported main arm 41, a nori tube gripping device is placed at an appropriate interval above the nori tube 11 so as to face the nori tube 11 which has reached its forward end position. A horizontal arm 4 having an approximately inverted U-shaped cross section and having an appropriate length corresponding to

Horizontal pressing surfaces 42a projecting downward are formed at both ends of this horizontal arm 42, and the nori basin 11 lifted by the lifting device 12 is pressed against the front and rear lifting plates 11 at the rising end thereof.
7 and 18 to be elastically clamped.

As shown in FIG. 2, this horizontal arm 42 is provided with left and right gripping portions 43A and 43B facing each other at a predetermined interval related to the width of the seaweed cage 11 to be gripped.

These opposing left and right grips 43A and 43B are located on both sides of left and right regulation shafts 44 and 44, respectively, which are pivotally connected to the horizontal arm 42.
Front and rear regulation pieces 46 with downward stoppers 45 protruding from them.
. . . are fixed respectively, and each regulating piece 46 . . .
A tension spring 47 is provided between the horizontal arm 42 and the horizontal arm 42.
are tensioned to bias each regulating piece 46 downward.

Further, left and right support shafts 4B and 48 are pivotally attached to both ends of the horizontal arm 42 located between the left and right regulation shafts 44, 44 and the stopper 45 of the regulation piece 46, respectively.
Gripping claws 49 facing the lower side of the regulating pieces 46 are fixed to both sides of the control piece 8, respectively.

A tension spring 50 is stretched between the outer end 49a and the regulating piece 46 of the gripping claw 49, and in the standby position shown in FIG.
are in contact with each other, and the tension of the tension spring 4T urges the outside of the gripping claws 49 that are in contact with each other downward.

As a result, the inner tip 49b of the gripping claw 49 is urged upward and comes into contact with the boss of the regulating piece 46, and the grasping claw 49, which has the claw portion 49C in contact with the regulating piece 46 and the lower inner side thereof, is moved upward as shown in FIG. It is maintained in the standby position shown in the figure.

Further, a rotary piece 5L51 corresponding to the guide pin 16 of the pushing-up device 12 described above is fixed to one shaft end of the left and right regulating shafts 44, 44, and the regulating shafts 44, 44
A locking piece 52 52 protruding from a notch 42 b opened on the upper surface of the horizontal arm 42 is fixed to the center of the horizontal arm 42 .
2, 52, and a return piece 54 that releases the engagement are integrally formed.
They are each pivoted at an angle of 8° 48 and biased downward by a torsion spring 56.

Therefore, in the standby position shown in FIG. 2, the locking/disengaging member 55 has the lower surface of the stop protrusion 53 in contact with the tip of the locking piece 52, and its return piece 54 is located above the suppressing surface 42a of the horizontal arm 42. Retained.

In the automatic cage hanging machine configured as described above, the sea cage 11 is supplied onto the roller conveyor 3 by an appropriate cage supply device (not shown), and as the transport roller 2 rotates, the first cage
It is conveyed from right to left in the figure, and at the forward end, the front end 11a abuts the front stopper 14 to be positioned in the front-rear direction.

Following this, the crank 30 of the lifting device 12 further rotates counterclockwise from the position shown in FIG.
pushes up the plate cam 28 on the pivot 25 and rotates the pivot 25 clockwise in the figure.

As the pivot 250 rotates, the swing arm 26 and the push rod 14 engaged therewith begin to rise from the lowest position (FIG. 1).

As the push-up rod 14 rises, the upper plate 15 fixed to its upper end, the front and rear push-up plates 17 and 18 elastically held on the upper plate 15, the press plates 1γ and 18, and the engaging arm 21a, 21
The cylindrical body 20 that is engaged or integrally constructed through the cylindrical body 20 rises, and the hook 23 that is vertically disposed on the cylindrical body 20 also rises at the same time.

Therefore, the seaweed cage 11 that was waiting at the forward end position of the roller conveyor 3 is placed on the front and rear push-up plates 17 and 18 provided on the top of the push-up device 12, and the cage gripping device 40 that is waiting above is pushed towards.

FIG. 4a shows the state of the nori cage 11 in its rising process and the grip part 43B on one side of the cage gripping device 40 waiting above the nori cage 11, and the nori cage 11 is at the rising end shown in FIG. When the guide pin 16 of the push-up device 12 approaches the rotating piece 5,
1, and the regulating piece 46 that was in the standby position (Fig. 4 a)
is rotated counterclockwise in the figure, and in conjunction with this, the gripping claw 49 on the support shaft 48 is also rotated in the counterclockwise direction in the figure.

As a result, the tip of the claw portion 49C of the gripping claw 49 moves downward from the standby position and comes into contact with the rising seaweed basin 11.

Although the gripping claw 49 is prevented from rotating toward the seaweed cage 11 by the contact, the rotating piece 51, the regulating piece 46, and the locking piece 52 continue to rotate counterclockwise in the figure. , locking piece 5
2 engages with the stop protrusion 53 of the detachable member 55, and the stopper 45 of the regulation piece 46 that was in contact with it separates from the grip claw 49.

For this reason, the gripping claw 49 holds the seaweed cage 1 under the tension of the tension spring 50.
It is urged toward the first side and is able to swing around the support shaft 48.

On the other hand, as shown in FIG. 5, the hook 23, which is rising together with the pusher rod 14, engages with the tip of the pusher arm 3γ that is waiting upward as it rises, and lifts the pusher arm 3γ so that the stacker 34 When turned clockwise in the figure, the stopper 34a of the stacking rod 34 is separated from the bearing plate 35, and at the same time, the engaging portion 34b at the lower end is displaced into the path 33a of the trochanter 33 attached to the swing arm 26. I'll come.

Then, the trochanter 33 of the swinging arm 26 approaching the rising end,
Engaging portion 34b at the lower end of the mallet 34 facing into the path 33a
Rotate the stacking rod 34 counterclockwise in the figure.

For this reason, the hook 23, the cylindrical body 20, and the front and rear push-up plates 17 and 18, which are rising, are pushed down slightly against the elasticity of the coil spring 190, and are placed on the push-up plates 11°18 and rise. The seaweed cage 11 also moves slightly downward within the swingable gripping area of the gripping claws 49 of the cage gripping device 40.

When the gripping claw 49, which is biased toward the seaweed cage 11 side, rotates around the spindle 48 following the downward movement of which seaweed cage 110, the claw portion 49c that was in contact with the seaweed cage 11 is now in contact with the seaweed cage 11. Tribute 1
It slides on the circumferential surface of 1a to change its contact position.

For this reason, for example, as shown in FIG. 4, even if the claw portion 49c does not directly enter the valley between the tribute rods 11a and abuts near the top of the tribute rod 11a at the time of first contact, the claw portion 49c As shown in Figure 4C, due to the above displacement action, the contribution 1 is ensured.
It enters the valley between 1a.

Then, when the trochanter 33 gets over the engaging portion 34b of the stacking rod 34, the stacking rod 34 is returned by the elasticity of the coil spring 190, the front and rear push-up plates 17, 18 also return upward, and the swinging arm 26 reaches the rising end. reach

Therefore, the seaweed cage 11 that has moved slightly downward within the gripping area of the gripping claws 49 rises again and the claw portion 49c of the gripping claw 49, which has entered the valley between the tribute rods 11a, is reliably penetrated between the tribute rods 11a. At the same time, it is elastically held between the pressing surface 42a of the horizontal arm 42 and the pushing plates 1γ and 18 at the rising end (Fig. 4d)
).

The action of the above-mentioned gripping portion is as follows:
Although this has been explained, the gripping portions 43A on the opposite side are also held at the same time in a direction symmetrical to the above, and the claw portions 49c, 49c of the left and right gripping claws 49, 49, which are oppositely provided, hold the tribute on both sides of the seaweed basin 11. 11a, respectively.

Next, when the push-up device 12 begins to descend from the rising end,
The seaweed basin 11, which was held between the push-up plates 1γ and 18 and the pressing surface 42a, also follows and descends, but at this time, the claw portions 49c are formed between the tribute rods 11a on both sides thereof.

The left and right gripping claws 49, 49, which have penetrated through the holes 49e, respectively, rotate outward to tightly grip the seaweed basin 11 (FIG. 4e).

Therefore, when only the push-down device 12 continues to descend further, it returns to the lowest position and waits.

In this way, the seaweed cage 11, which is tension-held by the left and right gripping claws 49, 49 provided oppositely to the cage gripping device 40, is then inserted into the mounting frame of the dryer (not shown) by appropriate means and emptied. The screen gripping device 40 returns to the standby position again, but at the time of this insertion, the return piece of the locking/disengaging member 55 of the screen gripping device 40 is pushed upward in the figure by the claw of the mounting frame (not shown). , the engagement between the locking piece 52 and the stop projection 53 is released, and the gripping portions 43A, 43B return to the standby position shown in FIG. 2.

Thereafter, the above-described operations are repeated to sequentially insert the supplied seaweed cages into desired dryers.

It should be noted that the present invention is not limited to the embodiments shown in the above embodiments, and in short, the present invention is not limited to the embodiments shown in the above embodiments. Any form is acceptable as long as it can be moved slightly up and down within the gripping area.

As described above, the present invention lifts the seaweed cages supplied onto a suitable conveyor from the conveyor at its advancing end, and uses the swingable gripping claws installed opposite to the cage gripping device waiting above the conveyor. By slightly moving up and down within the gripping area, the claws of the opposing swingable gripping claws slide on the circumferential surface of the tributary rods of the nori cage that they are in contact with, entering between the tributary rods and removing the lifted nori. Since the screen is gripped, no gripping errors occur, and the nori screen can be reliably gripped by the screen gripping device, and damage to the sho nori and nori screen due to gripping errors is completely eliminated.
It has the characteristics of improving operational efficiency and promoting labor saving.
