PURPOSE:To enable the circulation of an endless screen at a constant speed, by placing clamping rollers above driving rollers, and contacting the clamping roller to the surface of an endless screen circulating along the driving rollers. CONSTITUTION:Driving rollers 7 driven by the motor M are placed in parallel at the upper part of the drying chamber, and guide rollers 8 are placed in parallel at the lower part of the chamber 5. The endless screen to which laver sheet is attached is circulated in a zigzag pattern along the rollers 7, 8. Clamping rollers 10 is placed above the driving rollers 7, and are made to contact with the surface of the endless screen 2 circulating along the rollers 7. As a result, the endless screen 2 is circulated in the drying chamber 5 at a constant speed without causing the breakage and shrinkage of the laver sheet 11 attached to the screen 2 by the twisting of the screen 2. Furthermore, the damage of the screen 2 is suppressed even after the operation for a long period. There are various other advantages such as simple structure, easiness of production and maintenance, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seaweed drying device for an endless front type seaweed manufacturing machine, and more particularly to a device for conveying the endless front in a waveform within a drying chamber.

When drying the seaweed by conveying the endless front on which the seaweed is spread in a waveform in a drying chamber, various requirements are required of the conveying device for the endless front. In other words, (1) the endless front runs stably at a predetermined speed, (2) the endless front does not twist due to a speed difference on both sides of the endless front, and (3) the endless front does not twist even after long-term operation. (4) The structure is simple and easy to manufacture and maintain.

All of the above requirements are important. For example, if the endless front does not run at the specified speed or twists, the seaweed spread on the endless front may tear or shrink, and unnecessary Loads are applied locally, causing problems such as damage or damage to the endless front. Therefore, the present invention has been made for the purpose of providing a seaweed drying apparatus equipped with a novel endless transport means that meets the above requirements, and in which drive rollers are arranged in parallel at the upper part of the drying chamber, and the rollers are When adjusting the endless front on which the seaweed is spread and transporting the endless front by the roller, a nipping roller is provided above the roller and comes into contact with the surface of the endless front that circulates along the roller. In this way, the endless front is conveyed at a constant speed by the driving roller and the clamping roller.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of the endless front type seaweed manufacturing machine according to the present invention, in which numeral 1 denotes an endless chainer that engages an endless front 2 and conveys the endless front 2, a paper cutting section 3, a dewatering section 4 After passing through, it enters the drying chamber 5, and the front part of the drying chamber 5 is connected to the sprockets 81 to S5.
After traveling in a wave pattern along the drying chamber 5, it goes around the sprocket S6 disposed at the bottom of the drying chamber 5, and then around the sprocket S7 disposed at the rear bottom of the drying chamber 5, and then returns to the papermaking section 3 again. .

Reference numeral 7 indicates a number of cylindrical drive rollers arranged in parallel at the upper part of the drying chamber 5 behind the rotary wheel 6, and reference numeral 8 indicates a number of endless front rollers 2 arranged in parallel at the lower part of the drying chamber 5 corresponding to each drive roller. It is a guide roller that guides the downward bending part, and the endless front 2 separates from the endless chino 1 while going around the frontmost guide roller 8.
Thereafter, it travels in the drying chamber 5 in a wave pattern while rotating around each roller 7.8. Each driving roller 7 is driven and rotated by a motor M via an endless chino or sprocket S (fourth
(See also figure).

Reference numeral 10 denotes a nipping roller which is rotatably arranged around a rotating shaft 24 above each of the driving roller luffs, and its circumferential surface abuts the upper surface of the endless front 2 that rotates along the driving roller luff. It rotates together with the driving roller 7 and conveys the endless front 2 at a constant speed. In other words, this kind of endless front 2 is formed by weaving together thin rods made of a highly slippery material such as synthetic resin. Therefore, if the above-mentioned clamping roller 10 were not provided, the back side of the endless front 2 would be Although it will slip on the circumferential surface of the driving roller 7, making it difficult for the driving roller luff to convey the endless front 2 at a constant speed, the nipping roller 10 is arranged as described above, and both rollers 7. If the circumferential surface of the endless front 2 is brought into contact with both the front and back sides of the endless front 2 and both rollers 7 and 10 are rotated, the endless front 2 will be reliably conveyed at a constant speed.
The seaweed 11 spread on the endless front 2 will not be torn or shrunk as it is twisted as shown by the chain line in Figure 2. 22
is the rotation axis of the driving roller.

14.14 is a pulley consisting of a sprocket coaxially attached to the rotating shaft 17 above the roller 8,
On said pulley 14.14 there is a belt 15.15 made of chino.
One end of the chino 15.15 is attached to a ring-shaped bearing 13.13 loosely fitted on both sides of the rotating shaft 12 of each roller 8, and a weight 16 is attached to the other end. .1
6 is attached. That is, each roller 8 is suspended at its both ends by a pulley 14, a chino 15.15, and a weight 16.16.
The weight of 6.16 is slightly lighter than the weight of each roller 8, and therefore each roller 8 is lightly placed on the downward bending part of the endless front 2 so as to be able to rise and fall freely. The reason why each roller is lightly placed on the lower bent portion of the endless front 2 so as to be able to rise and fall freely is as follows. That is, the seaweed 11 spread on the endless front 2 gradually shrinks as drying progresses, and the endless front 2 also contracts accordingly, but when the endless front 2 contracts, it is placed on the downward bending part of the endless front 2. The roller 8 is raised (see dashed lines in FIGS. 2 and 3). If the roller 8 is raised as the seaweed 11 shrinks and the tension of the endless front 2 is loosened in this manner, the drying shrinkage of the seaweed 11 is allowed and the seaweed 11 will not be torn. Further, if the roller 8 is suspended by a weight 16, 16, the sensitivity of raising and lowering the roller 8 will be improved, and even if the endless front 2 is slightly compressed, the roller 8 will rise sensitively.

Furthermore, if the sprockets 14.14 are mounted coaxially as described above, both sprockets 14.14 always rotate by the same amount, so that the roller 8 can rise and fall straight without tilting to the left or right. That is, in FIG. 2, for example, if the amount of drying shrinkage on the right side of the seaweed 11 is larger than that on the right side, the roller 8 will be tilted as shown by the dotted line, and the endless front 2 will be twisted, causing the drying shrinkage on the right side of the seaweed 11 to be twisted. Not only does the seaweed 11 get damaged, but it also interferes with the constant speed running of the endless front 2, but since this device is configured as described above, the rollers 8 move up and down horizontally without tilting, so this problem does not occur. do not have.

In FIG. 5, reference numeral 20 denotes a guide member disposed on the side of each guide roller 8, and the end of the rotating shaft 12 of each roller 8 is fitted into the guide hole 21 of the guide member 20. guide you up and down in a straight line. 18 is a peeling roller arranged at the rear of the drying chamber 5, 19 is a winding roller, and the endless tube 2 after drying is carried out at the exit 2 at the rear of the drying chamber 5.
5, the nori 11 is peeled off when it goes around the peeling roller 18, and is wound up on the take-up roller 19, and the endless tube further goes around the roller 23, and then when it goes around the sprocket S5, it is It is reattached to the endless chino 1 and returns to the paper making section 3.

This device has the above-mentioned configuration, and the endless tube 2 runs in a wave pattern along each roller 7.8 to dry the seaweed 11 spread on the endless tube 2. .10
Since the endless tube 2 is held between the rollers 7 and 10 and conveyed by the rotation of both rollers 7 and 10, the traveling speed of the endless tube 2 is stable and the endless tube 2 is conveyed at a constant speed. Moreover, the endless tube 2 will not be twisted while the endless tube 2 is running, and the endless tube 2 will not be damaged due to local loads being applied to the endless tube 2.

FIG. 6 shows another embodiment of the present invention, in which a sheet 26 having a large surface roughness, such as linen cloth, felt, rubber, etc., is attached to the circumferential surface of the driving rollerf;
Endless tube 2 is secured by ensuring frictional resistance between the back surface of endless tube 2 and
It is designed to transport more reliably.

FIG. 7 shows still another embodiment of the present invention,
The circumferential surface 7a of the drive roller 7 is roughened to have an uneven surface.

By making the peripheral surface 7a of the roller 7 rough in this manner, frictional resistance is ensured between the roller 7 and the back surface of the endless tube 2, and the endless tube 2 is conveyed more reliably.

FIG. 8 shows still another embodiment of the present invention,
Three clamping rollers 30a are mounted on the upper part of the driving roller rough.
, 30b, and 30C are arranged, and each roller 30a to
30c is in contact with the non-spreading surface of the nori 1111 of the endless tube 2.

31 is a rotation axis.

As is clear from the above embodiments, various design changes are possible for the driving roller and clamping roller according to the present invention, and the key is to ensure mechanical resistance and frictional resistance between them and the endless tube 2. , any material may be used as long as it can transport the endless tube 2 reliably.

As explained above, the seaweed drying device of the endless tube type seaweed manufacturing machine according to the present invention has the driving rollers 7 driven by the power unit M installed in parallel in the upper part of the drying chamber 5, and the driving rollers 7 in the lower part of the drying chamber 5. Guide rollers 8 are arranged in parallel, and an endless tube 2 on which seaweed 11 is spread is run in a corrugated manner along the drive roller 7 and the guide roller 8. Since the clamping rollers 10 are arranged to come into contact with the surface of the endless tube 2 as it rotates along the path, the endless tube 2 runs at a constant speed in the drying chamber 5 and 1, and at the same time, the endless tube 2 is not twisted. The seaweed 11 spread on the endless tube 2 does not tear or shrink, and furthermore, even after long-term operation, the endless tube 2
It has various effects such as being less painful, having a simple structure, and being easy to manufacture and maintain.
