Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cushioning member for an aluminum-based extruded profile carrier, and generally relates to a cushioning member detachably attached to a carrier component such as each slat in the carrier. .

(Prior Art) In the extrusion processing of aluminum or its alloy, a heated billet is flow-formed from an extrusion tool by pressurization, and the extruded profile extruded from the extrusion tool is conveyed to a post-processing facility in a heated state. It is necessary to send it to a heat treatment furnace or the like. Therefore, aluminum processing plants are equipped with conveyors such as drive conveyors, walking beam coolers, and line-out tables, and lifting machines to move the extruded profile. In these transport machines, about 300
Hot extruded profiles of ~ 500 ° C are in direct contact with conveying components such as slats, for example in drive conveyors the extruded profiles are in direct contact with the surface of each slat. Since this slat is made of a heat-resistant metal, the surface of the extruded profile is easily damaged when it comes into contact with the extruded profile in the heated state. For this reason, conventionally, a cushioning material such as asbestos sheet or graphite is laminated on the surface of each slat. Recently, a heat-resistant web of aramid fiber is formed into a felt shape, and this felt sheet is bolted onto a slat or attached to the surface of the slat via a double-sided adhesive tape.

(Problems to be solved by the invention) When asbestos or graphite is used as a cushioning material, the flexibility is extremely low and the surface of the extruded profile is easily damaged, and dust scatters to deteriorate the working environment. On the other hand, the felt sheet has high flexibility and hardly damages the extruded shape member, but has relatively low heat resistance, and when it is continuously used at a temperature close to 500 ° C., it is blackened and worn, and the sheet often needs to be replaced. To do. At this time, if the felt sheet is bolted onto the slats, at least two bolts must be attached / detached with one slat for replacement, and one transport machine has several hundred slats. Replacing alone requires a large number of personnel and working days. Further, when the felt sheet is attached to the slat surface with the double-sided adhesive tape, it is necessary to completely peel off the remaining tape adhesive piece from the slat surface after the sheet is detached from the slat, and this peeling work is very difficult. If it is bothersome and the peeling work is rough, a difference in height will occur in the felt sheet after replacement, and the surface of the extruded profile will be damaged.

(Means for solving the problem) The present inventor has studied the attachment method of the heat-resistant cushioning member used in the carrier, and as a result, fixes a long holding plate on the back surface of the felt material and conveys slats and the like. By installing locking members on both ends of the part,
It was found that the highly flexible cushioning member can be easily attached to and detached from the slats of the carrier.

As shown in FIG. 2, a cushioning member 1 according to the present invention comprises a felt material 2 in which a web of heat resistant fibers is integrated into a sheet shape by needle punching, and the felt material generally has a thickness of about 10 to 12 mm. It is a flat rectangular parallelepiped or a diamond. The heat-resistant fiber used for the felt material 2 is, for example, aramid fiber alone or a blend of aramid fiber and carbon-based fiber, and the aramid fiber is para-phenylene terephthalamide fiber or meta-phenylene isophthalamide fiber. The former is preferable from the point of view, and the latter can be used at relatively low temperature. The carbon-based fibers used in combination include flame-resistant fibers having relatively low heat resistance and the like, and the content and quality may be appropriately selected according to the place of use. Punching during needling requires the penetration of a large number of needles in order to integrate a considerably thick web into a sheet.

A holding plate 3 having the same width is usually fixed to the back surface of the felt material 2, and this fixing is performed with an adhesive or a double-sided adhesive tape. The holding plate 3 is made of metal or plastic, and is preferably made of elastic spring steel or plastic that can be easily curved together with the felt material 2. Both ends of the holding plate 3 are made to project in the longitudinal direction from both end faces 4 of the felt material 2. On the other hand, in the transporting machine, locking members 8 are respectively installed at upper end portions 7 of both ends of the transporting component such as each slat 6, and both end portions of the holding plate 3, that is, the protruding portions 5 are detachably attached to the locking members. This locking member may be a metal fitting as shown in FIG. 2 or 3, or a round head pin (FIG. 4) or a clip (FIG. 6).

The cushioning member 1 of this invention is about 300
It can be attached to a carrier of the extruded profile 9 at ˜500 ° C. or a carrier used for the extruded profile after cooling. A drive conveyor, a walking beam cooling table, a line-out table, etc. can be exemplified as this type of carrier, and the felt material 2 may be cut according to the planar shape of the carrier parts such as the slats 6 to be applied. The aluminum-based extruded profile includes, in addition to pure aluminum and an alloy containing aluminum as a main component, a profile of an alloy containing a small amount of aluminum or having an extrusion temperature similar to those of these alloys.

(Operation) When the cushioning member 1 of the present invention is used, the extruded shape member 9 in a high temperature heated state is hardly contacted with the surface of the felt material 2 of heat resistant fiber and damaged. When exchanging the cushioning member 1, it suffices to fit the projecting portion 5 of the holding plate 3 fixed to the back surface of the felt material 2 into a locking member installed in a transport component such as each slat 6 in the transport machine. The cushioning member can be easily attached to and detached from the surface of the conveying component, and the cushioning member 1 is held by the slats 6 even when it is reversed.

(Embodiment) To explain the present invention with reference to the drawings, an aluminum-based extruded shape member 9 is heated in a heating condition as shown in FIG. Contact each slat 6 of. The felt material 2 used in this invention is, for example, aramid fiber and carbon fiber are uniformly mixed and integrated by needle punching to have a weight of 4000 g / m ₂ and a thickness of about 12 mm, and cut into a width of 50 mm and a length of 500 mm. To do. The holding plate 3 is made of spring steel having a thickness of 1 mm, and is adhered to the back surface of the felt material 2 with, for example, an epoxy resin so that both ends are projected by 15 mm. On the other hand, at the upper end portions 7 of both ends of the slat 6, the flat peripheral surfaces of the locking members 8 made of sheet metal are welded to the slat surface. The opening 11 of the locking member 8 has an inverted L-shape in longitudinal section, and the distance between the inner and rear walls of both openings is substantially equal to the length of the holding plate 3, and the cross section of the opening is opposite. The U-shape prevents the retaining plate 3 from shifting laterally. The buffer member 1 is fixed to the surface of the slat 6 by bending it like the one-dot chain line in FIG. 2 at the time of mounting and fitting both protrusions 5 into the locking member 8. After the fixing, the endless drive conveyor 10 is rotated, and the buffer member 1 does not fall off even if the slat 6 is reversed when returning. When the felt material 2 of the cushioning member 1 is worn out and needs to be replaced, it can be easily curved and detached from the locking member 8 by pulling it upward while holding the center of the cushioning member.

In the modification of FIG. 3, the locking member 12 has an inverted U-shape,
Both lower ends thereof are bolted to the upper side wall of the slat 13. If desired, a through hole 1 may be provided in the center of the locking member 12.
4 is provided, and after the cushioning member 15 is attached, the split pin 16 is formed in the hole 14 and the through hole of the holding plate protrusion 17 (not shown).
To insert. The split pin 16 does not have to be used as long as it is a transporting machine in which the rolling motion of the cushioning member 15 does not occur. Fourth
In the figure, the holding plate 22 of the buffer member 21 is a thin plastic sheet, and a long groove 24 is provided at the side end of the projecting portion 23 of the holding plate. On the other hand, round head pins 26, which are locking members, are vertically screwed into the screw holes on the surfaces of both ends of the slat 25, and the distance between the pins 26 is substantially equal to the distance between the inner rear walls of the long grooves 24, 24. Further, in FIG. 5, the locking member 31
Is hinged to a support plate 33 that is bolted to the upper end wall of the slat 32, and rises to the position indicated by the alternate long and short dash line by a spring (not shown). By this start-up, the cushioning member 3
Replacing 4 is easy, and an appropriate stopper (not shown) may be attached to the locking member 31 so that the buffer member does not come off due to impact. In FIG. 6, spring type clips 42 are installed as locking members at both ends of the slat 41. In this case, the cushioning member 43 may have the same shape as in FIG.

(Effect of the Invention) In the cushioning member according to the present invention, since the felt material is not hard like asbestos and graphite, the surface of the extruded shape member is not damaged, and the scattering of dust does not deteriorate the working environment. The felt material used in this invention is flexible and has relatively high heat resistance. The cushioning member of the present invention can be easily attached to and detached from the surface of an appropriate conveying component simply by fitting the protruding portion of the holding plate on the back surface of the felt material to the locking member such as each slat, and therefore the replacement thereof is easy. With the cushioning member of this invention, even if there are hundreds of slats in one carrier, this replacement can be done with a very small number of personnel in a short time, and it can be bonded when detached from the slats like double-sided adhesive tape. There is no need to remove the dust from the slat surface. In this invention, since the holding plate is continuously fixed to the felt material at the manufacturing site of the cushioning member, the work efficiency is higher than that of the case where the felt sheet is bonded to the surface of the conveying component one by one at the processing site of the aluminum-based extruded shape material. Remarkably excellent.
