DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver bundle bending apparatus for bending a laver bundle in which sheet-like dry laver is laminated.

[0002]

2. Description of the Related Art A predetermined number of sheets (usually 10 sheets) of laver sheets are laminated to form a laver bundle, and the laver bundle is folded in two and bound by a tape to be marketed. Will be shipped. Therefore, the present inventor has previously proposed various seaweed bundle bending apparatuses (Japanese Patent Publication Nos. 59-45341, 59-45342, 61-36901, 61-36901).
902).

[0003] In these laver bundle bending apparatuses, a laver bundle conveyed by a conveyor is pushed up from below by a plate-like push-up member and press-fitted between blade plates projecting at a pitch in an endless band. Is folded in two, and the laver bundle pressed between the blade plates is pushed out by a pushing member toward a binding device in a later process, and is widely used today by laver producers. .

[0004]

When the seaweed bundle on the conveyor is pushed up and folded between the slats by a push-up member, it is desirable to make both sides of the seaweed bundle neatly aligned. This will hinder the sending of the seaweed bundles to the subsequent process and bundling work.
By the way, there is considerable (about 1 to 2 cm) variation in the width of the dried laver produced by the apparatus for producing dried laver. This variation is mainly caused by variation in quality of raw laver which is a raw material of dry laver. Therefore, when a laver bundle folding mechanism is provided with a laver bundle aligning mechanism, it is necessary to cope with variations in the width dimension of the dried laver so that the laver can be finely aligned even if the width dimension varies.

Accordingly, an object of the present invention is to provide a seaweed bundle folding apparatus having an alignment mechanism capable of aligning both sides of a seaweed bundle neatly even when the width of the dried seaweed varies.

[0006]

According to the present invention, a plurality of blades, which are provided at a pitch on an endless belt adjusted to a rotating wheel and are provided with a pitch, and a laver bundle formed by laminating a predetermined number of dry laver are formed on a blade. Seaweed bundle bending comprising a conveyor for conveying the seaweed below, an alignment mechanism for aligning both sides of the seaweed bundle that has been conveyed, and a push-up member that pushes the seaweed bundle from below and bends and press-fits it between the blade plates. In the apparatus, the alignment mechanism rotates a pair of left and right alignment members erected on both sides of a laver bundle conveyed by the conveyor to a position above the push-up member, a rotation axis of the alignment member, and a rotation axis. By rotating the aligning member, the aligning member is pressed against both sides of the laver bundle, a pair of left and right members connected to the rotating shafts of the pair of left and right aligning members, and the members are connected to each other. The spring and the spring A stopper for defining an inward rotation limit of the member due to the spring force, and this stopper is a screw rod, and the horizontal position of the stopper is adjusted by the screwing amount to close the alignment member inward. The size of the interval can be adjusted.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of the laver folding apparatus, FIG. 2 is a front view of the same, FIG. 3 is a side view of a swing drive mechanism, and FIG. 4 is a front view of a swing minimum interval defining mechanism.

First, the overall structure of the nori bundle bending device will be described. In FIG. 1, an endless belt 2 is horizontally adjusted on a rotating wheel 1. The rotating wheel 1 is preferably a sprocket, and the endless belt 2 is preferably an endless chain. A large number of blades 3 project from the endless belt 2 at a pitch. Driven by a drive unit (not shown) such as a motor, the endless belt 2 is pitch-rotated along the rotating wheel 1 in the direction of arrow a, whereby the blade plate 3 is also pitch-rotated in the same direction. Reference numeral 4 denotes a laver bundle press-in guide roller provided opposite to the laver bundle press-in position.

In FIG. 1, a conveyor 5 is provided below the blade plate 3. This conveyor 5 is a belt conveyor. A predetermined number of sheet-shaped dry laver (usually 10)
The stacked laver bundle 10 is conveyed by the conveyor 5 in the direction of the arrow b, and hits the stopper 4 provided in front of the conveyor 5 and stops.

A plate-like push-up member 11 is disposed in an upright position below the laver bundle 10 stopped by hitting the stopper 4 (see also FIG. 2). The lower rear portion of the push-up member 11 is connected to a guide ring 12, and the guide ring 12 is slidably mounted on an upright guide rod 13. When the up-down movement mechanism (not shown) is driven, the push-up member 11 performs up-down movement.

Next, an alignment mechanism for aligning both sides of the laver bundle 10 on the conveyor 5 will be described. In FIGS. 1 and 2, a pair of left and right alignment members 20 are provided upright on both sides of the push-up member 11 so as to sandwich the laver bundle 10 on the conveyor 5 from the left and right. The alignment member 20 is formed of an elongated plate, and the lower end thereof is attached to the rotating shaft 21.
Reference numeral 22 denotes a bearing for the rotating shaft 21.

A short arm 23 extending horizontally horizontally is connected to the rotating shaft 21, and a pin 24 is provided upright at the tip of the arm 23 (see also FIG. 3). A presser 25 is provided above the pin 24. The pressing element 25 is attached to a rotating shaft 26. The rotating shaft 26 includes a rod 27,
28, a hinge 29 and the like. When the link mechanism is driven by being driven by a drive unit (not shown) such as a motor, the presser 25 swings up and down about the rotation shaft 26 (arrow c) and presses the head of the pin 24.

Next, an urging mechanism for urging the alignment member 20 inward (in a direction of pressing against the side surface of the laver bundle 10) will be described. 1 and 4, a pair of left and right rotation shafts 21 is shown.
An arm-shaped member 30 is provided upright and protruding from the distal end of the arm. In FIG. 4, a pair of left and right members 30 and 30 are connected by a spring 31. The spring 31 urges inward (the direction in which the members 30 attract each other).

In FIG. 4, reference numeral 32 denotes a stopper,
The inward rotation limit of the member 30 is defined. Stopper 32
Consists of a threaded rod and is screwed into the nut 33. The nut 33 is mounted on a bracket 34. Therefore, when the stopper 32 is turned, the stopper 32 moves horizontally in the longitudinal direction, and the position in the horizontal direction is adjusted. By adjusting the horizontal position of the stopper 32, the member 3
0 and the size of the interval W when the member 30 is closed can be adjusted.

Next, the swinging operation of the alignment member 20 will be described. In FIG. 2, the pressing element 25 rotates downward to
4, the rotating shaft 21 rotates in the direction of arrow e against the spring force of the spring 31, whereby the alignment member 20 rotates in the outward opening direction (arrow f), and likewise. The member 30 also rotates in a direction to open outward (arrow g) (see FIG. 4). 2 and 4, the alignment members 20 and 30 indicated by chain lines are in an open state. When the alignment member 20 is opened and the interval therebetween is large, the seaweed bundle 10 is conveyed by the conveyor 5 to a position above the push-up member 11.

Next, the pressing element 25 is rotated upward and the pins 24 are rotated.
4 is released, the member 30 rotates inwardly h by the spring force of the spring 31 in FIG.
Stop after hitting 2. Accordingly, the rotating shaft 21 also rotates in the opposite direction (arrow i), and the alignment member 20 also rotates inward (arrow j). The alignment member and the member 30 indicated by solid lines in FIGS. 2 and 4 show a closed state in this manner. By closing the alignment member 20 in this manner, the alignment member 20 presses against both sides of the laver bundle 10 on the conveyor 5 and aligns both sides of the laver bundle 10.

The width of the dried seaweed produced by the dried seaweed manufacturing apparatus varies considerably (about 1 to 2 cm). Therefore, the distance W '(FIG. 2) between the alignment members 20 is changed according to the variation of the width. It is desirable to adjust. Here, since the alignment member 20 and the member 30 are attached to the same rotating shaft 21, the interval W ′ between the alignment members 20 when closed is equal to the interval W between the members 30. Therefore, by adjusting the position of the stopper 32 in the horizontal direction, the position at which the member 30 closes in the direction of the arrow h is adjusted, whereby the interval W ′ between the alignment members 20 can be adjusted according to the width of the dried seaweed.

As described above, when the pressing element 25 swings up and down about the rotation shaft 26 to push and release the pin 24, the aligning member 20 swings in the directions of arrows f and j. As a result, both sides of the laver bundle 10 on the conveyor 5 are hit, and both sides are aligned. If the both sides are not aligned, the laver bundle 10 cannot be correctly sent to the subsequent process and bound.

The laver bundling apparatus has the above-described configuration, and the entire operation will be described next. In FIG. 1, a predetermined number of laver bundles 10 are carried by a conveyor 5 to a position above a push-up member 11. At this time, the alignment member 20 is rotated in the direction of arrow f in FIG. 2 and retreats sideways so as not to hinder the loading of the laver bundle 10. Next, the alignment member 20 is closed in the direction of arrow j (FIG. 2), and is pressed against both sides of the laver bundle 10 to align both sides, and the push-up member 11 is raised (arrow N in FIG. 1), and the laver bundle is raised. Push up 10. Since the push-up member 11 pushes up the center of the laver bundle 10, the pushed-up laver bundle 10 is folded into
And press-fitted between the blades 3 to be completely folded in two. Next, the push-up member 11 shifts to a lowering operation.

In FIG. 1, the endless belt 2 rotates at a pitch every time the laver bundle 10 is press-fitted between the slats 3,
Thereby, the folded seaweed bundle 1 is placed between the blades 3.
0 will be lined up. When the number of the seaweed bundles 10 folded between the slats 3 reaches a predetermined number (generally, 10 bunches), the seaweed bundles 10 are pushed out from between the slats 3 by means not shown in the drawing, and the next bundling process is performed. Transport to

By the way, there is a demand for an increase in the processing capacity of the laver bundle bending apparatus. Therefore, the present apparatus aims to increase the processing capacity as described below. In FIG. 2, the push-up member 11 moves up and down between a bottom dead center A shown by a solid line and a top dead center B shown by a chain line. The laver bundle 10 is intermittently sent above the lifting member 11.

Therefore, in the present apparatus, the push-up member 11 rises to the top dead center B, presses the laver bundle 10 into the blade plate 3 while pressing it in, and then moves to the descending operation to reach the bottom dead center A. The aligning member 20 is closed inward (when it has descended to the intermediate position C indicated by the broken line) to align both sides of the laver bundle 10. When the push-up member 11 reaches the bottom dead center A, the operation of aligning the laver bundle 10 is completely terminated. In this way, the push-up member 11 that has reached the bottom dead center A can be immediately shifted to the ascending operation, and the loss time of the operation of the push-up member 11 can be eliminated. As described above, by performing the up-down operation of the push-up member 11 and the swinging operation of the alignment member 20, it is possible to eliminate the loss time of the operation of the push-up member and to increase the processing capacity.

[0023]

According to the present invention, the interval when the aligning member is closed inward can be adjusted in accordance with the width of the dried laver produced by the apparatus for producing dried laver, so that the variation of the width of the dried laver is reduced. Even if there is, both sides of the laver bundle conveyed to the upper side of the lifting member by the conveyor can be neatly aligned and folded by the alignment member.
