DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a side plate of the cabinet, and a tapered first wire guide member 2 is attached to the side plate 1. A box 3 is provided outside the side plate 1 so as to surround the first wire guide member 2, and a lid 3 </ b> A is placed on the upper end of the box 3. A second wire guide member 4 is attached to the box 3 at a position corresponding to the first wire guide member 2.
Further, a seal mechanism 10 is provided at an intermediate position between the first wire guide member 2 and the second wire guide member 4 inside the box 3, and the seal mechanism 10 is configured as follows. Yes.
[0008]
This will be described below with reference to FIGS. In other words, a receiving case 11 having a V-shaped cross section (the angle formed by the left and right slopes in the example of FIGS. 2 and 3 is 90 degrees) is fixedly disposed at the lower part of the passage position of the wire. With respect to the case 11, a regular rectangular partition plate 12 provided with a through hole 12 </ b> A (see FIG. 4) in the center is brought into contact with the inner surface of the receiving case 11 and the upper half is turned upside down V The five brush insertion spaces 13 and 13 are defined by projecting in a letter shape and standing upright at an appropriate interval in the wire traveling direction (see FIGS. 1 and 4).
Further, on the inclined surface of the receiving case 11 corresponding to each brush insertion space 13, 13, shot punching holes 14, 14 are respectively drilled (see FIGS. 2 and 3).
[0009]
Four fiber brush bodies 15 and 15 having the following configuration are inserted into the brush insertion spaces 13 and 13 alternately and loosely inserted so that the fiber directions intersect from the upper left and right inclined openings of the brush insertion spaces 13 and 13. The fiber brush bodies 15 and 15 can move slightly back and forth.
That is, the fiber brush body 15 is formed in a regular square shape similar to the partition plate 12 and has a configuration in which a notch 16 extending from the center of the upper slope to the center is inserted. By alternately inserting the fiber brush bodies 15 and 15 into the brush insertion spaces 13 and 13 so that the fiber directions intersect with each other, the notches 16 and 16 also intersect with each other.
[0010]
Further, a lid 17 having an inverted V-shaped cross-section is provided above the receiving case 11 into which the fiber brush bodies 15 and 15 are loosely inserted and has a slight gap between the fiber brush bodies 15 and 15. A handle 18 is attached to the lid 17.
[0011]
Elastic bodies (for example, rubber plates) 19 and 19 are attached to the inner slope of the lid 17 and the inner slope of the receiving case 11 corresponding to the brush insertion spaces 13 and 13. Further, in the elastic body 19 attached to the inner slope of the receiving case 11 corresponding to the brush insertion spaces 13, 13, the positions corresponding to the shot holes 14, 14 Holes of the same diameter are drilled.
Furthermore, the elastic bodies 19 and 19 are not indispensable and may be selectively employed. However, by adopting the elastic bodies 19 and 19, an effect of preventing noise of the seal mechanism 10 during the blasting process can be obtained.
[0012]
In this configuration, the wire is inserted into the cabinet through the second wire guide member 4, the seal mechanism 10, and the first wire guide member 2 in this order from the direction of the arrow in FIG. I will project.
At this time, a part of the shot scattered in the cabinet 1 passes through the hole of the first wire guide member 2 and tries to jump out of the box 3 from the second wire guide member 4. 10 prevents the box 3 from jumping out. That is, the shot that has passed through the hole of the first wire guide member 2 collides with the right end partition plate 12 or the fiber brush body 15 in FIG. 1 and falls and is collected in the cabinet 1. The shot that has passed through the rightmost fiber brush body 15 collides with the next partition plate 12 or fiber brush body 15 and falls. Since this action is performed sequentially, the shots are reliably prevented from jumping out of the box 3.
The shots that have entered the brush insertion spaces 13 and 13 fall from the shot holes 14 and 14 and are collected in the cabinet 1.
[0013]
When processing another wire rod having a greatly different wire diameter, the lid 3A of the box 3 is removed, the lid 17 of the seal mechanism 10 is removed, and the fiber brush bodies 15, 15 are replaced with the desired fiber brush bodies 15, After the replacement, the cover 17 is covered and the cover 3A of the box 3 is simply covered, and the fiber brushes 15 and 15 can be replaced easily.
[0014]
Furthermore, since the fiber brush bodies 15 and 15 have a margin to be able to move slightly back and forth and upward in the brush insertion spaces 13 and 13, the fiber brushes 15 and 15 are not forcibly pushed and bent, and are not easily wrinkled. Therefore, the wrinkles of the fiber brush bodies 15 and 15 can be reduced.
[0015]
In addition, in the said Example, although the seal mechanism 10 is mounted | worn with the wire rod carrying-in port, the same effect is acquired even if it mounts | wears with a wire rod carrying-out port.
[0016]
Moreover, in the said Example, although the brush insertion spaces 13 and 13 were four places and the fiber brush bodies 15 and 15 were four bodies, it is not limited to this, The brush insertion spaces 13 and 13 are two or more places, The fiber brush bodies 15 and 15 should just be 2 or more.
[0017]
Further, a plurality of sets of the seal mechanisms 10 may be arranged in series at intervals.
The sealing property is improved as the number of the fiber brush bodies 15 and 15 is increased.
[0018]
Furthermore, in the said Example, although the partition plate 12 and the fiber brush body 15 are made into the regular square shape, it is not limited to this, For example, you may have a rhombus shape. The angle formed by the left and right slopes of the receiving case 11 is not limited to 90 degrees, and may be an angle corresponding to the rhombus shape.
