Japanese Patent Publication No. 3-39939

  Most of the seaweed producers are from the collection of seaweed to the production of dry seaweed, and the fishing factories near islands and large cities have limited production facilities due to land and financial constraints. On the other hand, laver drying devices are becoming larger in order to increase the production of laver. Therefore, for example, when laver is transported from the laver drying device with the front side facing up, the reversing device cannot be used to change the direction, and the front side is transported as it is and sorted by the foreign material shape sorter. Later, it will be arranged to turn about 90 degrees. However, when a new production line that introduces a large-sized laver drying device or a large-sized laver drying device is replaced and adapted to the carry-out amount, as shown by the one-dot chain line in FIG. Since the width is large and the width W of the production plant is narrow, the conventional layout is full just by placing a long foreign matter shape sorting device, and the undried detection device and the laver stain removal device in the previous process of the foreign matter shape sorting device are installed. There has been a problem that there is no place to install, and it becomes impossible to fit within the width W of the building wall.

  As described above, in an existing small building, when trying to introduce a large-sized laver drying apparatus, the arrangement of the laver drying apparatus and the next process apparatus is hindered.

  Thus, the present invention provides a dry seaweed dry laver direction change conveyor that can reduce the width direction of the laver production line, redirect the dry seaweed, and a dry seaweed production line that incorporates this conveyor to reduce the line width. .

  In the dry laver direction change conveyor of the present invention, an endless arc-shaped transport belt that changes the transport direction of dry laver is supported movably by conical rollers disposed at both ends of the transport belt, and the transport belt sucks dry laver. A plurality of air suction holes to be held in the transport direction, and a suction duct for sucking air from the air suction holes connected to the suction fan by a pipe between the conical rollers on the back surface of the transport belt. It is arranged.

  The piping may be provided with a suction force adjusting hole for adjusting the air suction force according to the degree of opening and closing of the lid. Further, a conveyor with a standing belt is disposed on the dry seaweed carrying side and dry seaweed unloading side of the endless arc-shaped conveying belt, and the standing belt has a standing belt opposed to each of both sides of the horizontal conveyor. Can be formed so as to widen toward the carry-in side of the dry seaweed and then in parallel to the carry-out side.

  Further, according to the present invention, the dried laver transported from the laver drying device with the front side up is sequentially conveyed to the undried detection device, the laver soil removal device, the foreign matter shape sorting device, the irregular discharge device, the folding device, and the binding device. In the dry seaweed production line in which the dried seaweed bundle is carried out, the dry seaweed direction changing conveyor is connected to the carry-out conveyor of the seaweed drying apparatus.

  In the dry seaweed direction change conveyor of the present invention, the dry seaweed is held on the transport belt by suction force, so that it can be redirected without being ejected outward from the conveyor by centrifugal force even when transported at a high speed.

  Moreover, in the dry laver production line of the present invention, since the width of the line can be reduced by incorporating a dry laver direction change conveyor, it has become possible to place it in a place that could not be placed in the conventional dry laver production line by increasing the size of the laver drying device. .

  FIG. 1 is a layout diagram of a laver production process to which the dry laver direction change conveyor of the present invention is applied.

  In FIG. 1, the dried laver unloaded from the laver drying device 1 by the unloading conveyor 1 a with the front side facing up is transported while the dried laver facing obliquely is aligned in the conveying direction by the conveyor 2 with the standing belt, and then the dried laver direction changing conveyor 3. It is transported while being turned about 90 degrees, and the dried seaweed that is turned diagonally by the conveyor 2 with the vertical belt is transported in the transport direction, transported to the next transport belt, transported, and undried The dried seaweed bundle is carried out by sequentially transporting it to the detection device 4, the laver dirt removing device 5, the foreign matter shape sorting device 6, the irregular discharge device 7, the folding device 8, and the binding device 9. In the present invention, by applying the dry seaweed direction changing conveyor 3, the dry seaweed production line can be controlled within the width W of the building where the conventional dry seaweed production line is arranged even if the laver drying apparatus 1 is enlarged. It becomes possible.

  2A and 2B show a dry laver direction change conveyor 3 according to the present invention, where FIG. 2A is a plan view, FIG. 2B is a side view, and FIG.

  In FIG. 2, an endless arc-shaped conveyor belt 10 having a fan-shaped center angle of about 90 degrees is supported on a dry laver direction change conveyor 3 movably by conical rollers 11 disposed at both ends of the conveyor belt 10. Has been. The outer circumferential side of the conveyor belt 10 is moved faster than the inner circumferential side by the conical roller 11 to change the direction of the conveying direction while conveying the dried laver.

  The speed of the conveying belt 10 of the dry seaweed direction change conveyor 3 is increased in the amount of dry seaweed (about 6000 to 10,000 sheets / hour) due to the increase in the size of the laver drying apparatus. 3 must be set to a high speed of 0.6 to 1 m / second by the variable speed motor 10a. However, when the dried seaweed unloaded from the laver drying device is placed on the arcuate conveyor belt 10 that moves at the above-mentioned high speed, the dried seaweed is light (about 3 g) and is therefore blown outward by centrifugal force. Cannot be transported to.

  Therefore, in order to prevent the dried seaweed from being blown outside by centrifugal force, the present invention sucks the dried seaweed as means for holding the dried seaweed on the transport belt 10 of the dry seaweed direction change conveyor 3 and holds the air on the transport belt. A suction hole 12 is formed. The air suction holes 12 formed in the transport belt are formed at equal intervals along the transport direction on the center line of the transport belt.

  A suction duct 13 for sucking dry laver from the air suction hole 12 is provided between the conical rollers 11 on both sides on the back surface of the transport belt 10, and a suction fan (not shown) is provided in the suction duct 13 by a pipe 14. Connected and sucked. In the middle of the pipe 14, a suction force adjustment hole 16 that adjusts the air suction force according to the degree of opening and closing of the lid 15 is formed.

  The air suction holes 12 provided in the transport belt 10 are transported while adsorbing dry nori. Since the adsorbing force does not act on the dry nori on the conical rollers 11 on both sides, the dry nori is easily carried in or out on the carry-in side and the carry-out side of the dry nori direction changing conveyor 3.
