Description

[Detailed description of the invention]

(a) Industrial Application Field The present invention relates to a method for producing seaweed. (b) Conventional technology Conventionally, nori manufacturing methods have involved circulating and transporting the seaweed cages in a conveying chain that circulates in the order of a slicing section, a dewatering section, a drying section, and a stripping section. There is now an automatic seaweed production method that automatically produces seaweed. (c) Problems to be solved by the invention However, since the quality of ingested raw seaweed deteriorates in a short period of time, it has been desired to improve the production speed, but conventional methods have an upper limit to the production speed. It was not possible to increase the manufacturing speed beyond that. The reason for this is that among the above steps, the papermaking process in particular relies on the flow of the papermaking water in which the nori dough is suspended before papermaking, and it is difficult to shorten the time required for this process. Moreover, the quality of the papermaking process has a decisive influence on the quality of the product nori. (d) Means for Solving the Problems In the present invention, a plurality of papermaking mechanisms arranged in front and back along the traveling direction of the conveyance chain simultaneously perform a papermaking operation on a plurality of cage frames. When transporting a plurality of front and rear screen frames that have been subjected to paper-making operations at the same time to the drying room, the drying chamber chain is intermittently conveyed the same number of times as the number of the front and rear paper-making mechanisms. To provide a seaweed manufacturing method characterized in that the cage frames are carried one by one into a drying room. (E) Effect In this invention, as described above, each of the above steps is simultaneously performed on the same number of seaweed cages as the number of sheets arranged, using a plurality of paper-making mechanisms arranged in series in the conveying direction, one after the other. Then, the conveyance chain is operated to transfer the screen from the conveyance chain to the drying room chain, and at this time, the drying chain is intermittently conveyed the same number of times as the number of paper-making mechanisms in front and behind it. By transporting multiple frames into the drying room one frame at a time, the papermaking process and intermittent conveyance operation were performed alternately, but this is now possible.
The time required for the papermaking process can be reduced by the number of times minus 1 from the number of sheets listed above, and the overall nori production speed is improved while ensuring sufficient time for each process of papermaking, dewatering, and peeling, which affect the quality of the product nori. It is something that can be done. (f) Effects According to the present invention, since a plurality of paper-making mechanisms are provided, a plurality of pieces of seaweed paper can be made in one paper-making operation, and therefore the time can be reduced by the number of pieces compared to the conventional method. Next, the operation of the drying chamber chain, which transports the seaweed produced in multiple pieces at the same time to the drying room and dries it, performs an intermittent conveyance operation the same number of times as the number of paper-making mechanisms, and then transports the seaweed produced in multiple pieces at the same time into a drying room. can be carried into the drying room one by one, which has the effect of increasing the production speed of seaweed. (G) Embodiments The embodiments of the present invention will be explained in detail based on the drawings.
A shows a seaweed production device, in which an endless conveyance chain 1 is suspended on the upper and lower stages of the device A, and the chain 1 is rotated to convey a cage frame with a seaweed cage stretched therein; In the upper stage, according to the conveying direction of the chain 1, from the right side to the left side, there are a paper making section 2,
The suction dehydration section 3 and the press dehydration section 4 are arranged in the above order, and the upper and lower drying chamber chains 7' and 7 have a cage frame suspended from the left end of the upper section to the upper and lower sections of the drying chamber 6 via the delivery section 5. The frame frame is passed to the upper stage side of the drying chamber 6, and the frame frame, which has gone around the upper and lower stages in the drying chamber 6 by the rotation of the same chain 7', is transferred to the conveyor chain 1 again.
The paper is transferred to the lower stage of the device A, and returns to the starting point, the paper-making section 2, via the stripping section 8 on the left side of the lower stage of the device A, in a cyclical operation. Seaweed is pasted onto the paper sheet 10 in the paper cutting section 2, and thereafter, while passing through the above-mentioned sections 3, 4, 5, 6, and 8, the product is subjected to processes at each section to produce a product nori. Next, to explain each part in detail, the paper cutting part 2 is as follows.
It consists of a papermaking frame 11 that moves up and down in synchronization with the intermittent operation of the conveyor chain 1, and a papermaking water supply mechanism 12 in which the seaweed dough is suspended. It is brought into contact with the upper surface of the basin 10 and the paper-making water supply fabric is made on the upper surface of the basin 10. Two such paper-making mechanisms 13 are installed in parallel, one behind the other in the conveying direction of the conveying chain 1. The two papermaking mechanisms 13 are operating simultaneously. In the suction dehydration 3, the upper surface of the suction box 14, which operates vertically, is brought into contact with the lower surface of the screen 10, and the vacuum inside the suction box 10 sucks and dehydrates the water from the paper-made seaweed. Like section 2, they are arranged in two rows, front and rear. The press dewatering section 4 presses the cage 10 to which the paper-made nori has adhered from above and below using a sponge water-absorbing part 16 that operates up and down, press-dehydrates the paper-made nori, and smooths the surface of the paper-made nori to produce product nori. It has the effect of increasing the gloss. Two press dewatering mechanisms 17 are also arranged in series. This press dewatering mechanism 17 has four dehydrating mechanisms 17 in total, two in the front and two in the front, and two more in total. The delivery section 5 has a vertical protruding section 1 which causes the conveying chain 1 to bend and travel in a substantially W-shape, and which protrudes leftward.
8, 19 and the right sides of the upper and lower drying chamber chains 7', 7'' that constitute the drying chamber chain 7, respectively, and the mechanism frame 9 is
The transfer operation is performed by a push-up roller 20 operating in synchronization with the conveyance chain 1 and the upper and lower drying chamber chains 7', 7'', and first to fourth guide plates 21, 22, which support the cage frame 9 from below during transfer. 23, 24,
This is performed by upper and lower folding guide plates 25, 26 and an auxiliary guide plate 27 for folding the screen frame 9,
The cage frame 9 passed to the upper drying room chain 7' is held in an upright state by the support frame 28 provided on the upper drying room chain 7', and the rotation of the chain 7' moves the cage frame 9 to the back left side of the drying room 6. It is conveyed to the drying chamber 6, turned around at the same back, and returned to the right entrance of the drying chamber 6, where it is passed to the lower drying chain 7'' via the delivery section 5, and conveyed inside the drying chamber 6 in the same manner as described above, and returned to the drying chamber 6. The paper-made seaweed that has reached the entrance and adhered to the screen 10 of the screen frame 9 evaporates moisture and dries as it passes through the upper and lower stages of the drying room once or twice, as described above, and is transported from here. The screen frame 9 that has climbed over the chain 1 enters the stripping section 8 on the left side of the lower stage of the device A. The stripping section 8 is opened by the operation of the upper and lower stripping rods 29 and 30 arranged in two rows on the left side of the section. The rear part of the dried seaweed that has adhered to the screen 10 is peeled off, and then the front part of the dried seaweed is peeled off by the operation of the front and rear peeling rods 32 and 32' arranged in two rows on the right side. The seaweed is completely stripped off and discharged to the outside of the apparatus A by a lower discharge conveyor 35.The stripping mechanism 31 is connected to the upper and lower rear stripping rods 2.
9, 30, front and rear stripping rods 32, 32', and main stripping rod 33 constitute a set of mechanisms. The operations of the conveyance chain 1, the upper and lower drying chamber chains 7, 7', and each part described above are all performed by transmitting power from a single main motor 36 through various interlocking mechanisms described below. , various interlocking mechanisms include a first chain 37 extending to the right from the main motor 36, a second chain 38 extending upward from the right end of the chain 37 and transmitting power to the suction dewatering section 3 and press dewatering section 4; Water absorption and dehydration section 3
A third chain 39 for transmitting power from the main motor 36 to the papermaking section 2, a fourth chain 40 for simultaneously operating the front and rear press dewatering mechanisms 17, and a fourth chain 40 extending to the left from the main motor 36. 5th chain 4
1. The conveyance chain 1 is driven by intermittently driving the seventh chain 44 through an intermittent drive mechanism 43 connected to the sixth chain 42 and the fifth chain 41 from the right end of the main chain 41 to the stripping section 8. . Further, power is transmitted to the delivery section drive mechanism 46 via an eighth chain 45 extending leftward from the left end of the fifth chain 41. Among the interlocking mechanisms, especially the intermittent drive mechanism 43
A rotary crank 47 connected to the left end of the fifth chain 41 causes a connecting rod 48 to reciprocate left and right, and the connecting rod 48 operates an inner and outer ratchet 49,
A swinging crank 52 pivotally supported on a ratchet shaft 51 having a ratchet 50 pivoted thereon swings back and forth, and a ratchet pawl 53 pivotally connected to the crank 52 and each ratchet wheel 4
The seventh chain 44 is made to rotate intermittently through engagement with the engagement teeth 9 and 50, and in particular, the outer shape of the inner ratchet wheel 49 interlockingly connected to the upper and lower drying chamber chains 7' and 7'' is is slightly larger than the external shape of the outer ratchet wheel 50, and the notch of the engaging teeth of the inner ratchet wheel 49 is larger than the deep and shallow engaging teeth 5.
4 and 55 are cut alternately, when the ratchet pawl 53 engages with the shallow engagement tooth 55, the outer ratchet wheel 50, which is interlocked with the conveyance chain 1, is not driven and only the inner ratchet wheel 49 is cut in one pitch. When the feed operation is performed (Fig. 3) and the ratchet pawl 53 engages with the deep engagement tooth 54, the inner and outer ratchet wheels 49,
50 The same pawl 53 engages with both engaging teeth, and the same car 4
9 and 50 operate to feed one pitch at the same time. (Figure 4). Therefore, the conveyance chain 1 operates once while the upper and lower drying chamber chains 7', 7'' operate twice.The inner and outer ratchet wheels 49, 50, the ratchet claws 53, the connecting rod 48, and the rotating crank 47 are driven intermittently. Another set of mechanisms 43 is arranged with a phase difference of 1 pitch, and by composing the operations of both intermittent drive mechanisms 43, intermittent operation is ensured. Each part is operated at the timing shown in the figure, and the relationship between the operation of each part and time is reduced. (a): Conveyance chain (b): Upper and lower drying chamber chains 7', 7'' (c): Push-up roller 20 of the delivery section 5 (d): Paper making frame 11 of the paper making section 2 (e): Water absorption pad 16 of the dewatering section 4 (f): Upper and lower rear stripping rods 29, 30 of the stripping section 8 (g) : Front stripping rod 32' of stripping section 8 (h): Main stripping rod 33 of stripping section 8 As shown in the figure, sufficient time is given to each process of paper cutting, suction dewatering, press dewatering, and stripping. , it can be seen that the two consecutive transfers and the delivery between the chains are done in a short time, and it can be seen that the manufacturing speed of the apparatus A as a whole is increased. In the present embodiment, each part has been explained as an example in which there are two sets in the front and rear, but a structure in which each part has three sets in the front and back or a plurality of sets in the front and back is also established by designing the intermittent drive mechanism. In addition, numeral 56 in the figure indicates a seaweed holding roller.
