[Configuration of laver machine]
First, a configuration of a laver making apparatus including a part of a laver forming apparatus according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a side view schematically showing a configuration of a laver making apparatus including a part of a laver forming apparatus according to one embodiment of the present invention, and FIG. 2 is a paper making up a component of the laver making apparatus. FIG. 3 is a perspective view showing the shape and arrangement relationship of the rolling roller and the material return roller, and FIG. 3 is the shape and arrangement relationship of the paper making / molding driving roller and the molding roller, which are constituent members of the laver forming apparatus in one embodiment of the present invention. (The paper making / molding drive roller is also a component of the seaweed paper making device).

As shown in FIG. 1, the laver machine 1 including a part of the laver forming device 17 (see FIG. 4) of the present embodiment includes four rollers 2 to 5 and four rollers 2 to 5. A conveying belt 6 stretched. The conveyance belt 6 is made of a water-permeable wire felt (conveyance wire felt belt). That is, the conveyance belt 6 has a water falling function that allows only water contained in the laver material 9 to pass therethrough and allows the water to fall without allowing the laver to pass therethrough. According to such a configuration, the falling water speed can be changed by selecting the size of the mesh of the conveyor belt 6 according to the size and shape of the laver contained in the laver material 9, so that the traditional paper-drawing method is used. It is possible to mechanically provide “paper making” in
Of the four rollers 2 to 5, the upper left roller 2 in FIG. 1 is a paper making roller (first roller). The upper right roller 3 in FIG. 1 is a papermaking / molding driving roller (second roller), and the papermaking / molding driving roller 3 is driven to rotate so that the conveying belt 6 continues in the clockwise direction in FIG. It can be moved (see white arrow ⇒ in FIG. 1). The conveying belt 6 is maintained in a substantially horizontal state between the papermaking roller 2 and the papermaking / molding driving roller 3, and a papermaking process is performed in the portion maintained in this horizontal state.

  A raw material homogenizing tank 7 for homogenizing the laver raw material 9 is arranged diagonally in front of the paper making roller 2, and the raw material is supplied to the bottom of the raw material homogenizing tank 7 with the rear obliquely downward. A nozzle 8 is connected. The nori raw material 9 is continuously supplied from the raw material homogenizing tank 7 through the raw material supply nozzle 8 onto the conveying belt 6 (see the black arrow in FIG. 1), and the nori raw material supplied onto the conveying belt 6 is supplied. 9 is continuously conveyed by the conveyance belt 6.

Since the conveyor belt 6 has a felt structure, water can be naturally dropped (naturally dropped) in the same manner as a slat.
In this case, the natural falling time of water can be arbitrarily set by selecting the coarse density of the felt network structure. That is, the conveyor belt 6 made of wire felt is a part of the “moving paper box”. If the natural fall speed at which water falls from the nori raw material 9 through the felt is set appropriately, the conveyor belt 6 can hold the raw water and move while gently dropping the raw water. The direction of supply of the laver material 9 (black arrow in FIG. 1) is the same as the direction of movement of the conveyor belt 6 (see white arrow in FIG. 1), and the water falling time is controlled. Therefore, the strength of the supply flow of the seaweed raw material 9 is also attenuated, and the “moving paper box” becomes a “stationary paper box” and realizes a state like “hand paper”. Can do.

  On the left and right sides of the conveying belt 6, a horizontally-long rectangular paper-making guide plate 10 is located at the front portion (between the paper-making roller 2 and paper-making dewatering rollers 13 a and 13 b described later) of the laver paper-making device 1. Are installed. If a pair of left and right paper making guide plates 10 are installed in this way, the water height (water retaining height) necessary for “paper making” by the conveying belt 6 can be maintained, and the width of the laver can be reduced. Can be molded to standard values.

  As shown in FIGS. 1, 2 (a), and 3 (a), each of the paper making roller 2 and the paper making / forming drive roller 3 is formed in an array having a small diameter at the center. As shown in FIGS. 1, 2 (b), and 3 (b), the conveying belt 6 is stretched around the small diameter portions of the paper making roller 2 and the paper making / molding driving roller 3. Here, the lengths of the small diameter portions of the paper making roller 2 and the paper making / molding driving roller 3 and the width of the conveying belt 6 are in conformity with the standard value of the width of one laver.

As described above, the paper making roller 2 and the paper making / molding drive roller 3 are formed in an array shape with a small central portion (the central portion is formed in a concave shape), and the seaweed material conforming to the seaweed standard 9 can be formed (having a width forming function for forming the width of the seaweed raw material 9), and the depth for maintaining the amount of water retained as a paper box can be maintained.
The water retention height is substantially the same height as the depth of the central portion (concave portion) of the paper making roller 2. Therefore, the nori raw material 9 after the nori raw material 9 is introduced can be suspended in a stationary state, and the effect of making the density distribution state of the nori raw material 9 uniform until the end of falling water can be obtained. As a result, the state of “the uneven distribution state of the density of the seaweed” that evaluates the quality of the dried nori that is the product is made uniform, and the quality of the product can be improved.
Increasing the production amount of dried laver can be easily dealt with by increasing the moving speed of the conveying belt 6. By stretching the small portion of the molding drive roller 3, it is possible to prevent meandering of the conveying belt 6 that physically occurs in such a case.
Further, if the pair of left and right papermaking guide plates 10 are installed on the left and right sides of the conveying belt 6 as described above, the stability of movement of the conveying belt 6 can be supplemented.

  As shown in FIG. 1 and FIG. 2B, the material return roller 11 is installed in a state where the material returning roller 11 is inserted into the central portion (concave portion) of the paper making roller 2 at an obliquely upper front of the small diameter portion of the paper making roller 2. The raw material return roller 11 is rotatable in the direction opposite to the rotation direction of the paper making roller 2. According to this configuration, the nori raw material 9 put on the conveying belt 6 can be returned to the paper making unit without being dropped outside by the raw material return roller 11 installed on the supply side of the conveying belt 6. Therefore, it is possible to mechanically provide “paper making” with less raw material loss. As a result, the production efficiency of dried nori can be increased by efficiently using the nori raw material.

As shown in FIG. 1, at the rear part of the laver making device 1 (near the position where the natural falling of the laver raw material 9 is completed), the two dewatering rollers 13a are in contact with the upper surface of the conveying belt 6. , 13b are installed. Here, the paper making and dewatering rollers 13a and 13b are formed with sponge at the outer peripheral portion (sponge roller), thereby uniformizing the compressive force applied to the surface of the laver raw material 9 and evenly finishing the surface. It becomes possible to do. Since the paper making and dewatering rollers 13a and 13b are sponge rollers as described above, they have a dewatering function of applying a slight pressure to the laver raw material 9. According to such a configuration, it is possible to perform preliminary molding for stabilizing molding quality and facilitating molding in the length direction.
In addition, it is possible to improve the quality of the dried seaweed by installing a plurality of stages of dewatering rollers 13a and 13b as described above and performing careful dewatering to sequentially increase the dewatering pressure.

  Sliding plates 14a and 14b, which are located on the back surface of the conveying belt 6 and receive the pressure of the paper dewatering rollers 13a and 13b, are respectively installed below the paper dewatering rollers 13a and 13b. Furthermore, dewatering vacuum chambers 15a and 15b are installed below the paper making and dewatering rollers 13a and 13b, respectively, behind the sliding plates 14a and 14b on the back surface of the conveying belt 6. The raw material 9 can be efficiently dehydrated.

On the left and right sides of the conveying belt 6, a horizontally-long rectangular auxiliary molding guide plate 16 located at the rear of the laver machine 1 (between the paper-making dewatering rollers 13 a and 13 b and the paper-making and molding driving roller 3). Are installed. If the pair of left and right forming auxiliary guide plates 16 are installed in this way, the shape change of the laver due to the compression of the paper making and dewatering rollers 13a and 13b can be suppressed to the standard value.
Further, if a pair of left and right molding auxiliary guide plates 16 are installed on both the left and right sides of the conveyor belt 6, the stability of the movement of the conveyor belt 6 can be supplemented.

  As described above, the function of the traditional paper box is added to the conveyor belt 6.

[Configuration of seaweed molding equipment]
Next, the configuration of the laver forming apparatus according to one embodiment of the present invention will be described with reference to FIGS.

  FIG. 4 is a side view schematically showing a configuration of a laver forming apparatus according to an embodiment of the present invention, and FIG. 5 is a flowchart showing a laver forming operation by the laver forming apparatus.

The seaweed molding process is a process of setting the shape of the seaweed to the standard value. Here, as shown in FIG. 5, in the paper making / molding process, a molding (seaweed width) process in which the width of the laver is sent out as a standard value, and a molding (seaweed) in which the length of the seaweed is standardized. The portion surrounded by a broken line in FIG. 5 is a molding part.
Hereinafter, a specific configuration of the molding unit (laver molding device) will be described.

As shown in FIGS. 1 and 4, the laver forming apparatus 17 of the present embodiment includes a paper making / molding driving roller 3 (second roller) installed on the carry-out side of the conveying belt 6 as a constituent member. ing.
As described above, the length of the small-diameter portion of the paper making / molding drive roller 3 matches the standard value of the width of one laver. That is, the paper making / molding drive roller 3 has a width molding function of molding the width of the laver raw material 9 by passing the small diameter portion. As a result, it is possible to mechanically provide “molding” that generates a laver width that conforms to the quality standard value of the laver and moves while maintaining the molding quality during continuous molding.

As shown in FIGS. 1, 3 (b), and 4, a molding roller 12 (third roller) is located behind and obliquely above the small diameter portion of the paper making / molding drive roller 3. Is placed in the vicinity of the papermaking / molding drive roller 3 in a state of being inserted into the central portion (concave portion) of the paper, and the molding roller 12 is in a direction opposite to the rotation direction of the papermaking / molding drive roller 3. It can be rotated.
As described above, the molding roller 12 is disposed in the vicinity of the papermaking / molding drive roller 3 in a state where the molding roller 12 is inserted into the central portion (concave portion) of the papermaking / molding driving roller 3. That is, the paper making / molding driving roller 3 and the molding roller 12 have a thickness molding function of molding the thickness of the laver raw material 9 by passing through a gap between them. Thus, it is possible to mechanically provide “molding” that generates a thickness of laver that conforms to the quality standard value of laver and moves while maintaining the molding quality during continuous molding.
Here, the arrangement position of the molding roller 12 is movable so that the gap between the paper making / molding driving roller 3 and the small diameter portion can be adjusted. And according to this structure, the clearance gap between the small diameter part of the paper making and the shaping | molding drive roller 3 and the shaping | molding roller 12 can be set to the gap | interval which can obtain the laver of arbitrary thickness. In this case, the thickness of the laver raw material 9 that has passed through the gap between the small diameter portion of the paper making / molding drive roller 3 and the molding roller 12 is equal to the set gap, so that the total thickness per laver is constant. It becomes. And since the whole nori raw material 9 is equalized in this way, it becomes possible to control to the continuous nori whose raw material amount is constant.

As described above, the molding roller 12 is disposed in the vicinity of the papermaking / molding driving roller 3 in a state where it is inserted into the central portion (recessed portion) of the papermaking / molding driving roller 3. Between the small diameter part of the drive roller 3 and the molding roller 12, a space (retention space) 18 in which the supplied laver raw material 9 can be temporarily retained is formed (see FIG. 3B). ). That is, the paper making / molding driving roller 3 and the molding roller 12 have a raw material temporary retention function for temporarily retaining the laver raw material 9. According to such a configuration, the excessive laver material 9 is automatically retained in the retention space 18, and an amount of the laver material 9 corresponding to the gap between the small diameter portion of the paper making and molding drive roller 3 and the molding roller 12, It can be made to flow into the gap. As a result, it is possible to obtain dried laver that always maintains a constant quality. That is, according to such a configuration, it is possible to mechanically provide “molding” that moves while maintaining molding quality such as the thickness of laver during continuous molding.
If the quality of the seaweed raw material 9 to be supplied is constant, the arrangement position of the molding roller 12 is moved to increase the gap between the small diameter portion of the paper making / molding driving roller 3 and the molding roller 12. By adjusting so, the supplied nori raw material 9 can be smoothly passed as it is.

  As shown in FIGS. 1 and 4, the back surface of the conveying belt 6 is positioned near the papermaking / molding driving roller 3 between the papermaking / molding driving roller 3 and the roller 4 to generate high-frequency vibrations. A raw material separation diaphragm 19 is installed. According to this configuration, the laver raw material 9 that has passed through the gap between the small diameter portion of the paper making / molding drive roller 3 and the molding roller 12 is peeled off from the conveying belt 6 by the fine high-frequency vibration of the raw material separation diaphragm 19. It becomes possible to separate. That is, the raw material separating diaphragm 19 has a raw material separating function for separating the molded laver raw material 9 from the conveying belt 6. The laver raw material 9 separated from the conveying belt 6 is continuously supplied onto a vibration conveying shooter 20 described later by its own weight.

As shown in FIG. 4, a vibration conveying shooter 20 that generates high-frequency vibration is installed below the paper making / molding driving roller 3. According to such a configuration, the laver raw material 9 that has passed through the gap between the small diameter portion of the paper making / molding driving roller 3 and the molding roller 12 by the fine high frequency vibration of the vibration conveying shooter 20 is maintained while maintaining the quality. It becomes possible to convey easily on the snowboard belt 21 of a process. This is because the fine high-frequency vibration reduces the friction coefficient of the vibration conveyance shooter 20 and applies a vibration force in the direction in which the laver material 9 moves.
Thus, the vibration conveyance shooter 20 has a conveyance function for conveying the molded laver raw material 9 onto the next-stage slatted belt 21. Here, the snowboard belt 21 is disposed below and behind the conveyor belt 6, and therefore, the vibration conveyance shooter 20 is disposed so as to be inclined downward toward the rear. And the moving speed of the laver raw material 9 can be made into the speed below a free fall speed by the inclination of the vibration conveyance shooter 20.
The vibration conveying shooter 20 can arbitrarily change the direction of inclination about the support shaft 20a (see arrows A and B in FIG. 4). According to such a configuration, the vibration conveyance shooter 20 is disposed so as to be inclined downward (toward the conveyance belt 6 side from the snowboard belt 21 side) at the time of starting the equipment and adjusting the equipment. It becomes possible to circulate the seaweed raw material 9 that has become unnecessary without being discarded.

  As shown in FIGS. 1 and 4, a cleaning spray 22 is provided on the back surface of the conveying belt 6 so as to be positioned near the roller 4 between the paper making / molding driving roller 3 and the roller 4. Thereby, the conveying belt 6 from which the laver material 9 is separated is cleaned by the cleaning spray 22 and returned to the paper making process.

As shown in FIG. 4, one molding cutter 23 is installed at a position opposite to the surface of the vibration conveyance shooter 20, and the molding cutter 23 is configured to be movable in a direction parallel to the vibration conveyance shooter 20. (See double arrow C in FIG. 4). The molding cutter 23 moves the nori raw material 9 that has passed through the gap between the small diameter portion of the paper making / molding drive roller 3 and the molding roller 12 and separated from the conveying belt 6 to the upper portion of the vibration conveying shooter 20. It can be cut at an arbitrary position such as immediately before, on the vibration conveyance shooter 20, or immediately after the lower portion of the vibration conveyance shooter 20. That is, the molding cutter 23 is configured so that the installation position can be freely changed, and has a length molding function of cutting the molded nori raw material 9 into a predetermined length.
The molded cutter 23 preferably has a rapid cutting function for rapidly cutting the nori raw material 9 at an arbitrary position. According to such a preferable configuration, it is possible to arbitrarily set the molding length of the laver raw material 9 and maintain the molding quality in the length direction. Moreover, since the nori raw material 9 can be cut | disconnected rapidly, without heating and deform | transforming, it becomes possible to maintain the quality of nori. Here, an ultrasonic cutter is used as the molding cutter 23. If an ultrasonic cutter is used, the laver raw material 9 can be quickly cut by ultrasonic vibration without being heated and deformed.

  As described above, a molding function is added to the carry-out side of the conveyor belt 6.

  1 and 4, reference numeral 24 indicates a vibration preventing roller, and reference numerals 25 and 26 indicate a snovel belt roller.

[Cutting position of seaweed material]
Next, the cutting position of the laver raw material in the laver molding apparatus of this Embodiment is demonstrated.

As shown in FIG. 5, the position (cutting position) at which the nori raw material 9 is cut is a place of timing that satisfies the standard value (length in the moving direction of the belt) L of one laver. The standard value L in the length direction of one laver is 190 mm determined in the industry.
Further, as shown in FIG. 5, the peripheral surface speed (moving speed of the conveying belt 6) of the small-diameter portion of the paper making / molding driving roller 3 is V, and the moving speed of the next-stage stool belt 21 is Vs. The interval between the nori raw material 9 on the snowboard belt 21 is Lg.

If the elapsed time from an arbitrary cutting time to the next cutting time is t, the travel distance Vs × t of the snoco belt 21 at the elapsed time t is L + Lg.
L + Lg = Vs × t (formula a)
Holds.
Similarly, since the rotation distance (movement distance of the conveying belt 6) V × t of the peripheral surface of the small diameter portion of the paper making / molding driving roller 3 at the elapsed time t is L,
L = V × t (formula b)
Holds.
From the above (formula a),
t = (L + Lg) / Vs (formula c)
From the above (formula b),
t = L / V (formula d)
Here, when Vs is a reference speed and the speed ratio S is defined as S = V / Vs, from the above (formula c) and (formula d),
S = L / (L + Lg) (Formula e)
Is guided.
When the above (formula e) is transformed,
V = L / (L + Lg) × Vs (Formula f)

Since L is constant at the standard value (190 mm) in the laver length direction, the above (formula f) is obtained on the snowboard belt 21 of the laver material 9 from which the set value of the moving speed V of the conveying belt 6 is cut. This is determined by the interval Lg.
Therefore, the papermaking / molding drive roller 3 is rotated (speed determining function) so that the peripheral surface speed (moving speed of the conveying belt 6) of the small diameter portion of the papermaking / molding drive roller 3 becomes V, and the nori raw material If the position of 9 is detected and cut by a sensor, the cut laver material 9 can be set on the slatted belt 21 at a predetermined interval Lg.
The interval Lg of the cut nori raw material 9 on the snovel belt 21 can be changed by changing the speed ratio S = V / Vs.
The molding speed of the seaweed length is affected by changes in the production speed of the dewatering section and the drying section, which are the subsequent production processes, but the peripheral speed of the small diameter portion of the paper making / molding drive roller 3 (conveying belt) 6) (moving speed 6) V and the moving speed Vs of the next-stage snowboard belt 21 can be appropriately changed.

  In the laver making apparatus 1 and the laver forming apparatus 17, the making / molding driving roller 3, the raw material returning roller 11 and the forming roller 12 are rotationally driven in synchronization by touching an operation panel (not shown). Has been. The raw material homogenizing tank 7 is also configured to start supplying the laver raw material 9 onto the conveying belt 6 by touching the operation panel. Further, the raw material separating diaphragm 19, the vibration conveying shooter 20, the slatted belt 21, the cleaning spray 22, and the molding cutter 23 are configured to start operations by touching the operation panel.

[Operation of seaweed molding equipment]
Next, the operation of the seaweed molding apparatus 17 of the present embodiment will be described.

  When the operation panel of the seaweed molding device 17 is touch-operated, the paper making / molding driving roller 3 is rotationally driven, and the conveying belt 6 starts to move in the direction of the white arrow ⇒ in FIGS. At this time, the paper making roller 2 also rotates in the same direction as the paper making / molding driving roller 3. In synchronism with the rotation of the paper making / molding driving roller 3, the material return roller 11 and the molding roller 12 rotate in the opposite direction to the direction of rotation of the paper making roller 2 and the paper making / molding driving roller 3, respectively. start. In addition, when the operation panel of the seaweed molding apparatus 17 is touch-operated, the raw material separation diaphragm 19, the vibration conveyance shooter 20, the slat belt 21, the cleaning spray 22, and the molding cutter 23 start their respective operations.

  Further, when the operation panel of the laver machine 1 is touch-operated, the raw material homogenizing tank 7 starts supplying the laver raw material 9 onto the conveyor belt 6. Thereby, the laver raw material 9 is continuously supplied onto the conveying belt 6 through the raw material supply nozzle 8. The laver material 9 supplied onto the conveyor belt 6 is continuously conveyed by the conveyor belt 6.

  The nori raw material 9 supplied onto the conveyor belt 6 is subjected to a paper making process until it reaches the two paper making and dewatering rollers 13a and 13b. The dehydration process is performed by the sliding plates 14a and 14b and the vacuum chambers 15a and 15b for dehydration.

  The nori raw material 9 after the dehydration process passes between the paper making / molding driving roller 3 and the molding roller 12. In this case, the nori raw material 9 is molded to the standard value of the width of one laver by passing through the small diameter portion of the paper making / molding drive roller 3. In this case, the laver material 9 is molded to a predetermined thickness by passing through a gap between the small diameter portion of the paper making / molding drive roller 3 and the molding roller 12.

  The nori raw material 9 that has passed between the paper making / molding driving roller 3 and the molding roller 12 is separated from the conveying belt 6 by the minute high-frequency vibration of the raw material separating diaphragm 19. The nori raw material 9 separated from the conveying belt 6 is cut by a molding cutter (ultrasonic cutter) 23 at a position immediately before moving to the upper portion of the vibration conveying shooter 20. The nori raw material 9 that has been cut and molded to the standard value is conveyed onto the next-stage slatted belt 21 via the vibration conveying shooter 20. The conveyor belt 6 from which the nori material 9 is separated is cleaned by the cleaning spray 22 and returns to the paper making process.

The seaweed raw material 9 conveyed on the snoco belt 21 is conveyed to the “dehydration step” before drying.
As described above, an efficient laver molding operation that does not cause a stop time is performed.

  In the above embodiment, the case where the conveying belt 6 is stretched around the four rollers 2 to 5 has been described as an example. However, the configuration is not necessarily limited to such a configuration. The conveyance belt may be stretched between at least two front and rear rollers.

  Moreover, in the said embodiment, although the case where the conveyance belt 6 consisted of wire felt was mentioned as an example, it demonstrated, It is not necessarily limited to such a structure. The transport belt only needs to have a water-falling function that allows only water contained in the seaweed raw material to pass through and allows water to fall without allowing the seaweed to pass through.

Moreover, in the said embodiment, although demonstrated taking the case where the one shaping | molding cutter 23 was installed as an example, it is not necessarily limited to such a structure. The number of molding cutters may be two or more.
Moreover, in the said embodiment, although the case where the shaping | molding cutter 23 consists of an ultrasonic cutter was mentioned as an example, it demonstrated and it was not necessarily limited to such a structure. A normal cutting blade can also be used as the molding cutter.

In the above embodiment, the length of the small diameter portion of the paper making / molding drive roller 3 (the width of the conveying belt 6) matches the standard value of the width of one laver. However, the present invention is not necessarily limited to such a configuration. As shown in FIG. 6, it is also possible to use a paper making / molding drive roller 27 in which the length of the small diameter portion (the width of the conveying belt) is the sum of the widths of a plurality of standard seaweeds.
In this case, as the molding cutter, as shown in FIG. 6, the molded laver raw material 29 is cut in the length direction (having a width molding cut function), and one or a plurality of first molding cutters 30 and molding One or a plurality of second molding cutters 31 that cut the laver raw material 29 in the width direction (having a length molding cut function) are used.
And according to this structure, the laver raw material 29 in which the whole width and thickness were adjusted by the paper making / molding drive roller 27 and the molding roller 28 is molded and cut into the width of each sheet by the first molding cutter 30. In addition, a plurality of sheets of standard seaweed can be formed by cutting the sheet into lengths for each sheet by the second molding cutter 31. As a result, a large number of laver can be simultaneously and continuously molded.
It is preferable that the 1st and 2nd shaping | molding cutters 30 and 31 have a rapid cutting function which cuts the nori raw material 29 rapidly in arbitrary positions. Here, ultrasonic cutters are used as the first and second molding cutters 30 and 31.
