Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing mechanism in a steam heat treatment apparatus for a rope, and more particularly, to a sealing mechanism for a rope steam heat treatment apparatus, and more particularly, an opening for introducing or leading out a rope into a sealed container filled with steam in order to heat treat the rope. This invention relates to a sealing mechanism for preventing steam leakage.

Conventionally, ropes have been heat-treated by so-called dielectric heating, in which a high-frequency electric field is applied after twisting strands and forming a rope.

The purpose of heat treatment is to eliminate the repulsive force caused by the twisting inside the rope, prevent it from losing its shape and kinging, increase its flexibility, and suppress changes over time.
The principle is that by heating the rope to a temperature slightly below the softening point of the rope, the direction of the molecular arrangement is corrected in the direction of twist, and the twisted state is the natural state for the rope's molecular arrangement. After making it so that it becomes , it is cooled and fixed in that state to eliminate the repulsive force. "King" means that the strands that make up the rope are twisted by the repulsive force caused by twisting due to rapid expansion and contraction of the rope.

However, although dielectric heating is very effective in generating heat for materials such as nylon, which has a relatively large loss coefficient, it generates almost no heat for materials with very low loss coefficients, such as polyolefin materials. Because they did not do so, they were not effective. For this reason, attempts have been made to add water with a very large loss of 4 to polyolefin materials, heat the water by dielectric heating, and use the heated water to heat the rope. multiply! It was extremely difficult to raise the pressure between the poles above atmospheric pressure. The part that guides the rope between the electrodes,
This is because, after the heat treatment, the portion that guides the rope to the outside between the electrodes must be opened. Therefore, the water temperature is also 1
The temperature of 100°C, which can be raised to 00°C or higher, is far below the softening point of polyolefin materials such as polypropylene, so the effect of heat treatment could hardly be expected. Furthermore, uniform heat treatment could not be expected due to uneven adhesion of water.

This rope steam heat treatment equipment was developed to eliminate the drawbacks of conventional heat treatment equipment that uses dielectric heating, and by using steam, uniform and effective rope heat treatment can be achieved. It is possible.

In this rope steam heat treatment apparatus, in order to introduce or lead out the rope into a sealed container filled with steam,
The opening must be sealed and the seal must not damage the surface of the running rope.

The present invention has been made in view of the above points, and it is an object of the present invention to economically provide a sealing mechanism that can seal a rope without damaging it using a simple mechanism.

That is, as shown in FIG. 1, the sealing mechanism in the rope steam heat treatment apparatus according to the present invention includes a pair of rotatable rolls (1) (1) each having a sealing mechanism for the rope running around the entire circumference of the roll (1). grooves (2) are provided symmetrically, and both rolls (1
) (1) A rope running space (81) having the same outer diameter as the rope is formed at the contact position of both nip tab grooves (2) (2), and the rope is passed through this rope running space (S). , the rope comes into close contact with both grooves (2) (2), and the roll (,
1) Since (1) slides and rotates following the movement of the rope, it does not damage the rope, and moreover, the rope tightly closes the rope running space (Sl).

Therefore, as shown in Fig. 2, a rope (aluminum introduction or outlet opening (2)
The pair of rolls (1) are provided in each of the α holes, the introduction or extraction opening (2) α groove is sealed, and the rope (Al is introduced or extracted through each rope running space (Sl), This prevents the enclosed steam from leaking.

Note that the steam heat treatment of the rope (Al) may be carried out by incorporating a steam heat treatment device into the final stage of the manufacturing process of the rope (A), or it may be set in the steam heat treatment device again after manufacturing the rope (A). It is okay to do so.

Next, the sealing mechanism in the rope steam heat treatment apparatus according to the present invention will be explained based on the embodiment shown in FIGS. 8 to 6.

As shown in FIG. 8, the steam heat treatment device αQ incorporated in the final stage of the rope manufacturing process is a sealed die Qη.

Rope introduction opening (a), rope lead-out opening (to)
and a steam supply section (not shown).The rope introduction opening (6) and the rope outlet opening (α) are the same except that the running direction of the rope (Al) is different. The sealing mechanism will be explained based on the rope lead-out opening 0 shown in FIGS. 4 to 6.

The outlet opening 03, which is removably fixed to one end of the sealed container Ql), is formed into a rectangular cylinder and communicates with the sealed container αυ.

On the other hand, at the center of the roll (1) formed in a cylindrical body in the generatrix direction, a rope running groove (2) having a semicircular cross section is formed in an annular shape over the entire circumference.

These rolls form a pair and are removably pivoted to the frame body (3) in a parallel and closely spaced state, and are also attached to the outlet opening (2), and both rolls (1) (1)
The sealed container
pThe inside and outside are communicated.

Moreover, since the lead-out opening Q1 is sealed by both rolls (l bar 1), the tip corner tube part of the lead-out opening a3 has two pairs of facing faces (141Qf9), one of which faces α→ is chevron-shaped. The roll (1) and the roll (1) fit into the concave part formed by the roll (1), and the other opposing surface Qυ contacts both rolls (1) and (1) parallel to each other, and the roll (1) ) are respectively provided on the other opposing surface Q to fit into the grooves (2).

The material of these rolls (1) is heat resistant (to withstand steam temperature) and wear resistant (to slide with the opening).
For example, a hard silicone rubber foam can be considered.

Similarly, the introduction opening (2), which is removably fixed to the other end of the sealed container, is also formed into a rectangular cylindrical body, communicates with the sealed container aυ, and is pivoted to the frame (3). A pair of rolls (1) (1) are attached to the introduction opening (b), sealing the introduction opening (6), and the grooves (2) (2) of both rolls (1) (1) Rope running space formed fs)
The inside of the sealed container αυ communicates with the outside through.

As described above, the sealed container 0■ is connected to the outside only through the rope running space (Sl(S)) at the introduction opening (2) and the outlet opening 01. The rope (through the rope running space (Sl) into the sealed container ap
A) is inserted, and when the rope (Al) is taken out through the rope running space (S) of the lead-out opening (2), both rope running spaces + 5lfS are sealed tightly by the rope (A). Become.

Moreover, when the rope [A] is run, both openings (2) α
Each roll of cucumber (1) (1) has both openings (2)
(to) and rotate in sliding contact with each other, so both rope running spaces (Sl (Sl) are allowed.

Therefore, when steam is supplied to the sealed container (b) and the rope (Al is run) for heat treatment, the steam does not leak from the rope (N introduction or outlet openings (a) and (2)). Moreover, the rope (Al) will not be damaged.

Furthermore, when both the openings (6) and (2) are made into removable cylinders, it becomes easy to modify and attach the container to an existing sealed container.

Furthermore, when a pair of rolls is detachably formed, a roll (1) having a groove (2) for running the rope that matches the diameter of the rope is formed.
It is very convenient to change the loft to a rope with a different diameter.

By the way, with the normal sealing mechanism that uses a labyrinth, it takes time to set the rope and the labyrinth itself is expensive, so changing the loft to a rope of a different diameter takes time and the setup is expensive. There's a problem.

In the above example, a pair of rolls (L) (1) which are pivoted to the frame (3) from the outside are brought into close contact with the tips of both openings (2). As shown, a pair of rolls (1) are inserted into the cylinder at the tip of both openings (LXl (2)
The same effect as described above can be obtained even if both rolls (1) (1) are opened on both sides and removably directly attached to the opening (Ll (2)).

As mentioned above, the sealing mechanism in the rope steam heat treatment apparatus according to the present invention is such that the rope (in the rope steam heat treatment apparatus C1l for heat treating Al, the rope length) is introduced by passing through the sealed container αυ filled with steam. Alternatively, a pair of rotatable rolls (1
) (1) and grooves (2) for running the rope around the entire circumference of the roll (1).
(1) Forming a rope running space (S) in the nip between
The rope (A) is introduced or led out through this rope running space (S), so the rope is not damaged.
It can be easily sealed and can be provided economically.

Moreover, the introduction or exit opening (2) of the rope fAl←
Forming the cucumber into a removable cylindrical body allows it to be easily attached to an existing sealed container αV, which is convenient.

In addition, the pair of rolls (1) and (1) are removably formed, making it easy to change lots to heat treatment for ropes of different diameters.
It's even more convenient.

In the illustrated example, one pair of rolls is provided for each opening, but if multiple pairs of rolls are provided for each opening, the sealing performance will be even higher, and it can also be used in cases where high sealing performance is required. .

In addition, in order to ensure high sealing performance, when a pair of rolls is brought into close contact with each opening, each roll should be provided with a rotation mechanism that is linked to the rope running, so that the rolls do not rotate due to the rope running.
