Description

[Detailed description of the invention]

(a) Industrial application field This invention relates to a seaweed manufacturing device. (b) Conventional technology Conventionally, nori production equipment has a conveyor chain that circulates in the order of a slicing section, a dewatering section, a drying section, and a stripping section. There was an automatic seaweed production device that automatically produced seaweed. (c) Problems to be solved by the invention However, since the quality of collected raw seaweed deteriorates in a short period of time, it has been desired to improve the production speed, but there is an upper limit to the production speed with conventional equipment. It was not possible to increase the production speed any further. 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 this invention, a paper cutting section, a press dehydration section, and a stripping section that operate in synchronization with an endless conveyance chain that intermittently conveys the screen frames, are provided in the conveyance direction of the same chain. A drying chamber chain is installed at the end of the chain to operate synchronously, and the papermaking section is composed of a plurality of papermaking mechanisms. All the operations are configured to operate intermittently in synchronization at the same time, and the conveyance chain is intermittently conveyed the same number of times as the number of multiple papermaking mechanisms during the papermaking stop after one papermaking operation in the papermaking section. It is an object of the present invention to provide a seaweed manufacturing apparatus which is configured so that, as the conveyance chain performs the intermittent conveyance operation, the drying chamber chain also performs the intermittent conveyance operation the same number of times. (E) Effect In this invention, as described above, each of the above processes is performed simultaneously 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, and then The intermittent conveyance operation of the conveyance chain for transferring the bamboo baskets from the conveyance chain to the drying room chain is performed continuously for the same number of papermaking mechanisms as mentioned above, so that the transfer of the bamboo baskets is possible. In the present invention, the drying process can be carried out dynamically in a short time while the conveyance chain is moving, and the drying time can be ensured by extending the drying chamber or by configuring the conveyance path in two upper and lower stages. The paper-making process is performed simultaneously on multiple paper-making frames, and the conveyor chain performs intermittent conveying operations several times in succession during the subsequent paper-making stop time, which is different from the conventional paper-making process. The paper-making process time, which used to be carried out alternately with the conveyance operation, can be omitted by the number of times minus 1 from the number of sheets mentioned above, and the time required for each process of paper-making, dewatering, and peeling, which affect the quality of the product nori, can be reduced. It is possible to improve the overall seaweed production speed while ensuring a sufficient amount of seaweed. (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. Then, the operation of the drying chamber chain, which transports a plurality of pieces of seaweed simultaneously into the drying chamber and dries them, is the same intermittent conveying operation as the conveying chain in the sheeting section.Moreover, the conveying chain Since the intermittent conveyance operation is performed the same number of times as the number of paper-making mechanisms while the paper-making mechanism is stopping, multiple pieces of seaweed that are made at the same time can be carried into the drying chamber one by one, making it easier to dry than before. This has the effect of increasing the manufacturing speed by using the chamber loading mechanism as is. (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 end and lower section 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 made a round trip to 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 delivered to the lower stage and returns to the starting point, the stripping section 2, via the stripping section 8 on the left side of the lower section 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. The suction dehydration unit 3 is designed to bring the upper surface of a suction box 14 that moves vertically into contact with the lower surface of the screen 10, and to suck and dehydrate water from the paper-made seaweed using the vacuum inside the suction box 10. Like the opening part 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 ends of the upper and lower drying chamber chains 7', 7'' that constitute the drying chamber chain 7, respectively, and the transfer operation of the screen frame 9 is carried out by the conveyance chain. 1 and upper and lower drying chamber chains 7', 7'' and a push-up roller 2 that operates synchronously.
0 and the first to fourth guide plates 21, 22, 23, 24 for supporting the screen frame 9 during delivery from below, and the upper and lower folding guide plates 2 for folding the screen frame 9.
5, 26 and the auxiliary guide plate 27, and the cage frame 9 passed to the upper drying room chain 7' is maintained in an upright state by the support frame 28 provided on the chain 7'. By the rotation of 7', it is transported to the back left side of the drying chamber 6, turned back 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 is carried out in the same manner as described above. The paper-made nori adhering to the screen 10 of the screen frame 9 that has been transported through the drying chamber 6 and has reached the entrance of the drying chamber 6 again loses moisture while going around the upper and lower stages of the drying chamber once and twice. has evaporated and dried, and the cage frame 9 transferred to the conveyance chain 1 enters the stripping section 8 on the left side of the lower stage of the apparatus A. The stripping section 8 is arranged in two rows, front and rear, on the left side of the same section. The upper and lower rear stripping rods 29 and 30 are activated to peel off the rear part of the dried seaweed that has adhered to the screen 10, and then the front and rear peeling rods 32 and 32' arranged in two rows on the right side are activated to remove the dried seaweed. The front part is peeled off, the seaweed is completely peeled off using a suction roller 34, and the seaweed is discharged from the apparatus A by a lower discharge conveyor 35.The peeling mechanism 31 is connected to the upper and lower rear peeling rods 2.
9, 30, the front and rear stripping rods 32, 32', and the 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 which is interlocked with the sixth chain 42 and the fifth chain 41 from the right end of the 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 the connecting rod 48 to reciprocate from side to side, and the connecting rod 48 rotates the inner and outer ratchet wheels 4.
A swinging crank 52, which is supported by a ratchet shaft 51 which supports the cranks 9 and 50, is swung back and forth.
The seventh chain 44 is caused to rotate intermittently through the engagement between the ratchet pawl 53 pivotally connected to the second chain and the engaging teeth of the respective ratchet wheels 49 and 50.
In particular, the external shape of the inner ratchet wheel 49 interlocked with the upper and lower drying chamber chains 7' and 7'' is the outer ratchet wheel 50.
The notch of the engagement blade of the inner ratchet wheel 49 is slightly larger than the outer shape of the engagement tooth 5.
4 and 55 are cut alternately, when the ratchet pawl 53 engages with the shallow engagement tooth 55, the outer ratchet wheel 50 connected to the conveyor chain 1 is not driven and only the inner ratchet wheel 49 is driven one pitch. When the feed operation is performed (Fig. 3) and the ratchet claw 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 (Fig. 4). Therefore, the conveying 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 rotary 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 , and the relationship between the operation of each part and time is shown. a is the conveyance chain 1 b is the upper and lower drying chamber chains 7', 7'' c is the delivery section 5 push-up roller 20 d is the paper making frame 11 of the paper making section 2; e is the water absorption part 16 of the dewatering section 4; f is the upper and lower rear stripping rods 29, 30 of the stripping section 8; The stripping rod 32'h is the main stripping rod 33 of the stripping section 8. As shown in the figure, sufficient time is given to each process of paper cutting, suction dehydration, press dehydration, and stripping, and two consecutive transfer and chain operations are performed. It can be seen that the delivery between the parts is 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, an example in which each part has two sets in the front and rear has been described, but a structure in which each part has three sets in the front and back or a plurality of sets can also be realized depending on the design of the intermittent drive mechanism. In addition, numeral 56 in the figure indicates a seaweed holding roller.
