By the way, since the above-mentioned conventional device repeatedly adsorbs the nori seaweed by air at the adsorption part, when the nori seaweed is adsorbed, the nori seaweed powder (small pieces of the nori seaweed, fine powder) is also taken together with the nori seaweed. I will inhale. Therefore, a filter is provided in front of the blower in the air suction path so that the nori powder is not sucked into the blower by the filter.

However, in the above configuration, nori powder accumulates on the filter, which reduces the suction force, so that maintenance such as periodic cleaning of the filter is required.

In addition, there is also a problem that fine seaweed powder passing through the filter is sucked into the blower, resulting in a decrease in suction power.

Further, in order to press the square nori in the conventional nori stocker forward, the driving force of a motor or the like is used (for example, Patent Document 2), but the device becomes complicated and large, so that the pressing is simpler. A mechanism was desired.

The present invention has been made in view of the above-mentioned conventional problems, and by providing a cyclone type seaweed powder separator in the air suction path of the square seaweed, the suction power can be reduced by centrifuging the air and the seaweed powder. The purpose is to provide a seaweed supply device that is easy to maintain.

Another object of the present invention is to provide a seaweed supply device that simplifies the entire device by using a pressing mechanism for square seaweed that does not require power such as a motor.

In order to achieve the above object, the present invention
First, the seaweed adsorption part moves to the seaweed adsorption position and adsorbs the square seaweed of the seaweed stocker, and when the seaweed adsorption part returns to the seaweed supply position, the adsorption is released and the square seaweed is released one by one. In the seaweed supply device that supplies seaweed from the seaweed supply position to the seaweed winding portion, when the seaweed adsorption part is at the seaweed adsorption position, the air suction path configured from the seaweed adsorption port to the air exhaust port of the seaweed adsorption part. A blower is provided in the subsequent stage, a cyclone type seaweed powder separator is provided in the air suction path between the blower and the seaweed suction port, and the air adsorbing the square seaweed is the cyclone by the suction operation of the blower. The seaweed powder is introduced into the separator from the circumferential direction of the type seaweed powder separator and rotated in a spiral shape to centrifuge the seaweed powder, and the air after the seaweed powder is centrifugally separated is the cyclone type seaweed powder separator. It is configured to be discharged from the air exhaust port by the blower through the upper opening of the inside, and the blower is provided on the upper opening of the cyclone type seaweed powder separator.

It is composed of a rear link mechanism, and a weight for rotationally supporting the front link in a direction of pushing it forward is installed on a fixed rotation shaft at the lower end of the rear link mechanism. It is configured by the seaweed supply device according to any one of 3 .

The front side link can be configured by, for example, a long link (24). The rear link mechanism is composed of, for example, a parallel link composed of a long link (23), an intermediate link (26), a short link (25), a long link (24), a rotary support shaft (26b, 24a, 26a, 25a) and the like. Can be configured. With this configuration, the entire device can be simplified because the pressing mechanism for pushing the square seaweed in the seaweed stocker forward does not require power.

According to the present invention, air that sucks square nori and contains nori powder is introduced into a cyclone-type nori powder separator in the air suction path, and the air rotates in a spiral shape in the separator to cause nori powder. Is centrifugally separated, and the separated seaweed powder is accumulated on the bottom surface of the cyclone type seaweed powder separator, and the air without seaweed powder is discharged from the air outlet through the blower from the upper opening of the cyclone type seaweed powder separator. Therefore, it is not necessary to provide a filter for recovering the seaweed powder, the maintainability can be improved, and the deterioration of the blower performance due to the clogging of the filter can be suppressed.

In addition, the suction force due to the large static pressure of the blower can be applied to the cyclone type seaweed powder separator, and air and seaweed powder can be efficiently separated.

Further, the separated seaweed powder is accumulated on the bottom surface of the casing below the seaweed powder separation disk, and the backflow to the upper part of the casing is suppressed, so that the seaweed powder can be reliably separated from the air.

Further, for the accumulated seaweed powder, it is only necessary to remove the cyclone type seaweed powder separator from the centrifugal blower and the seaweed powder separation disk from the casing to exhaust the seaweed powder accumulated at the bottom of the casing. In addition to improving maintainability, since no filter is used, there is no need to clean the filter, nori powder is accumulated in the filter, and the suction power does not decrease.

Further, the air obtained by centrifuging the seaweed powder is sucked upward through the upper opening through the mesh plate from the air introduction opening of the upper surface opening small diameter cylindrical portion, so that the air containing the seaweed powder is tentatively. However, even if it is introduced into the opening for introducing air, the suction of the seaweed powder is blocked by the mesh plate, so that the seaweed powder is not sucked into the blower and the suction performance is not deteriorated.

Further, the inside of the casing can be divided into a storage space below the disk and a separation space above the disk by the seaweed powder separation disk, and the seaweed powder once dropped below the seaweed powder separation disk. The backflow to the separation space can be reliably prevented, and the seaweed powder can be efficiently centrifuged.

Further, since the pressing mechanism for pushing the square seaweed in the seaweed stocker forward does not require power, the entire device can be simplified.

The upper surface of the centrifugal suction machine 42 as a blower is fixed to the rear position of the central space 38 on the back surface side of the machine frame 5 (see FIG. 4). The centrifugal suction machine 42 is a blower (centrifugal blower) having a cylindrical fan such as a sirocco fan or a turbo fan, and sucks air in the vertical direction from below the center thereof (direction of arrow H in FIG. 4). Air is discharged from the exhaust port 42a in the rear direction (FIG. 7, arrow I direction). The central portion of the fan on the lower surface of the centrifugal suction machine 42 communicates with the central circular opening 40d'of the cyclone type seaweed powder separator 40.

The upper edge of the rectangular housing 52 surrounding the centrifugal suction machine 42 is fixed to the back surface of the machine frame 5 around the centrifugal suction machine 42 (see FIG. 8), and is attached to the bottom surface of the housing 52. Is formed with an opening 52a communicating with the central circular opening 40d'of the cyclone type seaweed powder separator 40. The cyclone type seaweed powder separator 40 is detachably fixed to the back surface of the housing 52 so that the central circular opening 40d'is connected to the opening 52a so as to coincide with the opening 52a.

In the housing 52, a plurality of air exhaust ports 52b are provided in the direction of the exhaust port 42a of the centrifugal suction machine 42 inside (see FIG. 8), and the air from the centrifugal suction machine 42 is the air from the centrifugal suction machine 42. It is configured to be discharged rearward from a plurality of air exhaust ports 52b.

The cyclone-type seaweed powder separator 40 having such a configuration is detachably fixed to the central space 38 and the back surface of the housing 52. In the detachable structure, an engaging claw may be provided at the upper end portion of the casing 40b, and an engaging hole may be provided at a corresponding position between the central space portion 38 and the lower surface of the housing 52, or the back surface of the housing 52 may be provided. It is also possible to provide two rails, provide a protrusion that engages with the rail at the upper end of the casing 40b, and engage and mount the casing 40b on the lower surface of the housing 52 while sliding the casing 40b from the rear surface side of the housing 52. can.

Alternatively, the machine frame 5 itself is centered on the axis along the short side direction of the rear end portion of the machine frame 5, and the seaweed stocker 16, the air duct 37, and the casing 52 are all in the arrow L direction (see FIG. 4). ), On the other hand, the cyclone type seaweed powder separator 40 is placed on the mounting portion 3a on the machine frame 3 on the lower surface of the machine frame 5 as shown in FIG. When the machine frame 5 is rotated in the direction opposite to the arrow L direction and returned to the original position, the opening 52a of the housing 52 and the central circular opening 40d'of the casing 40b are formed. The connection port 39 of the central space portion 38 and the connection port 40c'of the connection space portion 40c of the casing 40b can be configured to be connected in a sealed state. With this configuration, the machine frame 5 can be opened in the direction of the arrow L, and then the cyclone type seaweed powder separator 40 can be easily taken out from the above-mentioned placing portion 3a. In any case, the cyclone-type seaweed powder separator 40 is configured to be easily removable from the machine frame 5, and when the seaweed powder accumulated in the cyclone-type seaweed powder separator 40 is discarded, the above-mentioned After opening the lid 40d, the seaweed powder separation disk 50 is removed from the casing 40b, the casing 40b is inverted, and the seaweed powder accumulated on the bottom surface of the casing 40b is easily discarded in a trash box or the like. It is configured to be able to.

Since the present invention is configured as described above, the operation of the seaweed supply device of the present invention will be described below.
As shown in FIG. 3, it is assumed that a plurality of square seaweed N are vertically stored in the seaweed stocker 16. Therefore, the square seaweed N in the stocker 16 is stored in the stocker 16 with a predetermined thickness from the rearmost portion N1 to the frontmost portion N2. Then, the pressing portion 19a comes into contact with the square seaweed N of the rearmost portion N1 due to the urging force of the engaging piece 29 by the weight 28 of the pressing mechanism 20 in the direction of the arrow G, and the entire square seaweed N is pressed forward. With the seaweed end locking pieces 18 and 18 in contact with both ends of the square seaweed N of the front portion N2, the entire square seaweed N stands still in a state of being urged forward on the seaweed stocker 16. There is.

Further, it is assumed that the seaweed adsorbing portion 30 is located at the seaweed supply position X2 in FIG. In this state, when the centrifugal suction machine 42 is driven to start and continue the air suction operation, the suction operation in the arrow H direction toward the center of the centrifugal suction machine 42 is performed, so that the upper surface of the machine frame 5 is used. External air is sucked into the air ducts 37 and 37 from the two air suction ports 35 and 35, and the air reaches the connecting space 40c from the central space 38 through the connecting ports 39 and 40c', and is further cyclone type. It is introduced from the air inlet 40a of the seaweed powder separator 40 into the inside of the casing 40b of the separator 40 from the circumferential direction, and while rotating in a spiral shape (FIG. 7, arrow q1 direction) in the separation space K1, the center. The centrifugal suction machine 42 is sucked upward along the central axis M of the casing 40b through the mesh plate 45'between the openings 48 and 49 of the small diameter cylinders 43 and 44 having the upper surface opening of the portion, and is sucked upward from the central circular opening 40d'. It is sucked into the center of the sirocco fan and discharged in a direction perpendicular to the central axis, is exhausted into the housing 52 from the exhaust port 42a of the centrifugal suction device 42, and is further discharged from the air exhaust port 52b on the rear surface of the housing 52 to the outside. Is exhausted to. By driving the centrifugal suction machine 42 in this way, an air suction path from the air suction ports 35 and 35 to the air exhaust port 52b of the housing 52 is formed.

After that, when the drive motor M1 of the seaweed adsorption unit 30 is driven, the pulley 31a of the drive motor M1 rotates, whereby the seaweed adsorption unit 30 is moved to the seaweed supply position X2 and the seaweed adsorption position X1 by the crank mechanism 31. In between, the reciprocating motion is started.

In the reciprocating motion, when the seaweed adsorption portion 30 recedes to reach the seaweed adsorption position X1, the seaweed adsorption port 33 comes into contact with the plate surface of the square seaweed N in the front row of the seaweed stocker 16. When the seaweed adsorption portion 30 is located at the seaweed adsorption position X1, the two connecting ports 34, 34 on the bottom surface of the seaweed adsorption portion 30 are located on the two air suction ports 35, 335, so that the air suction ports are located. The air suction action by the 35 and 35 extends to the inside of the seaweed adsorption unit 30, and air is sucked from the plurality of seaweed adsorption ports 33 on the rear surface of the seaweed adsorption unit 30 toward the inside of the adsorption unit 30.

Therefore, one of the square seaweed N in the front row is sucked by the seaweed adsorption port 33 of the seaweed adsorption unit 30, and the one square seaweed N is adsorbed by the seaweed adsorption unit 30, and the seaweed is adsorbed in the adsorbed state. The portion 30 advances to the seaweed supply position X2. Then, since the two connecting ports 34, 34 of the seaweed suction portion 30 are separated from the air suction ports 35, 35, the air suction action by the seaweed suction port 33 is released, and the seaweed suction portion 30 is adsorbed. The square seaweed N that has been used falls downward while being guided by the seaweed drop guide 10, and is supplied to a predetermined position of the intermittent rotating rice ball transport disk 9.

After that, the rice ball R is attached to the square seaweed N that has fallen due to the intermittent rotation of the intermittent rotation rice ball transport disk 9, and the square seaweed N is wound around the rice ball R by the seaweed winding portion 11 of the next stage. Gunkanmaki R'is formed.

The retreat-advancing operation of the seaweed adsorbing portion 30 is repeated, and when retreating, one of the square seaweed N in the front row of the seaweed stocker 16 is adsorbed, and when adsorbing, the adsorption is similarly released and the square seaweed N is intermittent downward. The operation of being dropped and supplied to the rotating rice ball transport disk 9 is repeated and continuously performed. Then, when the square seaweed N is adsorbed by the seaweed suction port 33 in the process in which the seaweed suction unit 30 repeatedly adsorbs the square seaweed N, it is present on the surface of the square seaweed N from the seaweed suction port 33. Nori seaweed powder is also sucked together with the sucked air.

Therefore, the air containing the seaweed powder is sucked into the seaweed adsorbing portion 30 from the seaweed adsorption port 33, and the air is drawn from the two connecting ports 34 and 34 of the seaweed adsorbing portion 30 to the air suction ports 35, respectively. It is sucked into each air duct 37, 37 through 35, passes through the central space 38, enters the connecting space 40c from the connecting port 39, 40c', and further enters the connecting space 40c from the air introducing part 40a in the cyclone type seaweed powder separator 40. Input from the circumferential direction into the separation space K1.

Then, the suction air containing the seaweed powder is separated around the upper surface opening small diameter cylinder 43 (around the central axis M) in the casing 40b as shown in FIG. 7 in the cyclone type seaweed powder separator 40. It rotates in a spiral shape (in the same direction in the direction of arrow q1) in the space K1, and by this rotation, the solid seaweed powder is separated from the air by centrifugal force and is blown in the inner peripheral direction of the casing 40b, in the direction of arrow q1. While rotating in the same direction as the air flow, it falls in the casing 40b due to its own weight, and falls from the notches 51 and 51 of the seaweed separation disk 50 into the accumulation space K2 below the disk 50 and is accumulated. go.

The seaweed powder that has fallen into the accumulation space K2 has the seaweed separation disk 50 above it, and the accumulation space K2 is separated from the separation space K1 by the disk 50, so that the inside of the accumulation space K2. The seaweed powder is accumulated and accumulated in the accumulation space K2 without the seaweed powder flowing back into the separation space K1 again.

Therefore, the air in the separation space K1 in which seaweed powder does not exist is intermediate from the openings 48 and 49 of the upper surface opening small diameter cylinders 43 and 44 due to the continuous suction force in the central axis M direction of the centrifugal suction machine 42. The small-diameter cylinder 44 is sucked inward (direction of arrow q2 in FIG. 7) and is sucked upward along the central axis M of the cyclone-type seaweed powder separator 40, and is sucked upward along the central axis M of the cyclone-type seaweed powder separator 40. The powder separator 40 is sucked into the center of a fan (for example, a sirocco fan) in the centrifugal suction machine 42 from the central circular opening 40d', and is discharged from the exhaust port 42a of the centrifugal suction machine 42 by the fan, and further, a casing. It is exhausted to the outside from the air exhaust port 52b of the body 52.

Even if the seaweed powder is sucked into the opening 48 together with the air, since the mesh plate 45'is provided in the opening 48, the seaweed powder is sucked into the upper surface opening small diameter cylinder 43. Nori seaweed powder is separated in the direction of the inner peripheral surface of the casing by centrifugal force on the swirling air flow, and is finally collected and accumulated in the accumulation space K2.

In this way, the seaweed powder that has reached the cyclone type seaweed powder separator 40 through the air path is surely separated from the air by the separator 40, and is contained in the accumulation space K2 below the seaweed powder separation disk 50. It will be accumulated.

The suction operation is continued, and after the seaweed powder is accumulated in the accumulation space K2 of the casing 40b, the casing 40b of the cyclone type seaweed powder separator 40 is removed from the housing 52 and the central space 38. The lid 40d is removed from the casing 40b together with the top opening small diameter cylindrical portions 43 and 44, the protrusion 53a is pinched by hand, the seaweed powder separation disk 50 is removed from the casing 40b, and the seaweed accumulated on the bottom surface of the casing 40b. The powder may be discarded in a trash box or the like.

Therefore, unlike the conventional case, it is not necessary to clean the filter and the like, and the nori powder is not clogged in the centrifugal suction machine 42 to reduce the suction power.

In the above embodiment, the case where the seaweed powder separation disk 50 is provided at the bottom of the cyclonic type seaweed powder separator 40 has been described, but even if the seaweed powder separation disk 50 is not installed, air and seaweed powder can be generated in the casing 40b. Since the seaweed powder is separated by centrifugation and similarly accumulated at the bottom of the casing, it is not necessary to perform maintenance such as cleaning the filter as in the conventional apparatus, and a sufficient effect such as improvement of maintenance can be obtained. Of course, by installing the seaweed powder separation disk 50, it is possible to prevent the backflow of the seaweed powder, and it is possible to perform more reliable separation of the seaweed powder.

As described above, according to the present invention, the air containing the seaweed powder by sucking the square seaweed N is introduced into the cyclone type seaweed powder separator 40 in the air suction path, and the air swirls in the separator 40. The seaweed powder is centrifugally separated by rotating in a shape, and the separated seaweed powder is accumulated on the bottom surface 40e of the cyclone type seaweed powder separator 40, and the air containing no seaweed powder is opened above the cyclone type seaweed powder separator 40. Since the air is discharged from the air discharge port 52b through the centrifugal suction machine 42 from the portion, it is not necessary to provide a filter for collecting seaweed powder, which can improve maintainability and the centrifugal suction machine due to clogging of the filter. Performance degradation can be suppressed.

Further, the suction force due to the large static pressure of the centrifugal suction machine 42 can be applied to the cyclone type seaweed powder separator 40, and air and seaweed powder can be efficiently separated.

Further, the separated seaweed powder is accumulated in the bottom surface 40e of the casing 40b from the notch 51 of the seaweed powder separation disk 50, and the backflow to the upper part of the casing 40b is suppressed, so that the seaweed powder is surely separated from the air. Can be done.

Further, for the accumulated seaweed powder, the cyclone type seaweed powder separator 40 is removed from the seaweed supply device 1, and the seaweed powder separation disk 50 is removed from the casing 40b, and the seaweed powder accumulated in the bottom portion 40e in the casing 40b is removed. Since it is only necessary to exhaust the air, maintainability can be improved, and since the filter is not used, there is no need to clean the filter, nori powder is accumulated in the filter, and the suction power is not reduced.

Further, the air obtained by centrifuging the seaweed powder is sucked upward from the air introduction opening 48 of the upper surface opening small diameter cylindrical portion 43 through the mesh plate 45'through the upper opening, so that the seaweed is temporarily separated. Even if the air containing the powder is introduced into the air introduction opening 48, the suction of the seaweed powder is blocked by the mesh plate 45', so that the seaweed powder is sucked into the centrifugal suction machine 42 and the suction performance is deteriorated. There is no.

Further, the inside of the casing 40b can be divided into a storage space K2 below the disk and a separation space K1 above the disk by the seaweed powder separation disk 50, and once dropped below the seaweed powder separation disk 50. It is possible to reliably prevent the backflow of the seaweed powder into the separation space K1 and efficiently centrifuge the seaweed powder.

Further, since the pressing mechanism for pushing the square seaweed N in the seaweed stocker 16 forward does not require power, the entire device can be simplified.

According to the present invention, in a seaweed supply device that sucks square seaweed by air, the seaweed powder and air can be centrifugally separated by a cyclone type seaweed powder separator, so that maintenance such as frequent filter cleaning is not required. It is possible to provide a high-performance seaweed supply device that does not deteriorate the suction performance due to clogging of the filter.
