[Prior Art] Conventionally, molten aluminum is used at the rear equipment of an aluminum extrusion press, specifically at a cooling table that cools the molded product and transfers it to the next process after extruding the molten aluminum. After extrusion, the temperature is 400℃.
As a cooling table belt for transferring aluminum molded products to the next process while cooling them at temperatures between 650°C and 650°C, a felt member (cushion) made of a mixture of carbon fiber and aromatic polyamide fiber is attached to the back side of the flat belt member. A belt with felt is used, in which members (members) are bonded together (see, for example, Japanese Patent Laid-Open No. 2-154833).

0003

[Problems to be Solved by the Invention] By the way, the temperature of the aluminum molded product, which is the object to be transported by the felt belt, is quite high as described above, so if the length of the aluminum molded product is long (for example, 50 m), Aluminum molded products have a problem in that during transportation, a difference in cooling rate occurs in the longitudinal direction, resulting in a temperature difference, which causes a difference in thermal contraction in the longitudinal direction, causing warpage in the aluminum molded product.

An object of the present invention is to provide a felt belt that can suppress warping in the longitudinal direction of the transported object due to the difference in thermal shrinkage when transporting a long transported object at high temperatures. purpose.

[0005]

[Means for Solving the Problem] The invention as claimed in claim 1 is characterized in that a sheet-like heat-resistant felt member is disposed on the back side of an endless power transmission belt member over the entire circumference of the belt, and the belt can be used for a long time at high temperatures. Assuming that the belt is a felt belt that conveys a conveyed object of approximately 100 mm in diameter, a metal member having a predetermined height and disposed on the back side of the felt member at a predetermined interval in the longitudinal direction of the belt is engaged with the power transmission belt member. and an attachment member for removably attaching the metal member to the power transmission belt member.

The invention according to claim 2 further includes a cover member made of the same material as the felt member and covering the metal member.

[0007]

[Operation] According to the invention of claim 1, the felt belt is configured such that a long conveyed object at a high temperature such as an aluminum molded product is positioned between the metal members, and the longitudinal direction of the conveyed object is conveyed. Even if the transported object tries to warp or deform in the front-rear direction in the horizontal plane due to the difference in thermal contraction due to cooling during transport, the transported object will not move forward or backward. In contact with the metal member located,
Deformation is regulated, and the occurrence of warping of the transported object during transport is suppressed.

According to the second aspect of the invention, since the metal member is covered with the cover member, direct contact between the high-temperature conveyed object and the metal member is avoided.

[0009]

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

In FIG. 1 showing the overall configuration, reference numeral 1 denotes a felt belt for conveying a conveyed object W such as a long aluminum molded product at high temperature, and a metal block member 2 having a predetermined height is attached to the back side of the felt belt. , are removably disposed by attachment members 3 at predetermined intervals in the longitudinal direction of the belt.

The felt belt 1 has carbon fibers and aromatic polyamide fibers, for example, on the back side of the toothed belt member 4, which has teeth portions 4a and tooth valley portions 4b arranged alternately over the entire circumference of the belt. A felt member 5 made of a sheet-like heat-resistant felt material with a thickness of 4 mm to 16 mm is bonded with an adhesive.

Further, the periphery of the block member 2 is covered with a cover member 6 made of the same material as the felt member 5 to prevent the objects to be transported from coming into direct contact with the block member 2. Both ends of the cover member 6 are connected to the block member 2
and the felt member 5, and the mounting member 3
By attaching the block member 2, it is clamped and fixed.

The block member 2 has a width approximately comparable to the belt width, is made of, for example, an aluminum alloy, and has a substantially semicircular cross section with a curved surface 2d on the upper surface, as shown in FIGS. 2 to 4. An upper part 2a with a shape and a lower part 2 with a rectangular cross section
b, and screw holes 2c, 2c are screwed into the upper and lower sides of these.

The mounting member 3 is made of, for example, an iron plate, and as shown in FIGS. 5 to 7, it approximately corresponds in length to the tooth valley portion 4a of the toothed belt member 4 and is engaged with the tooth valley portion 4a. a connecting board portion 3a; a side plate portion 3b extending upward from both ends of the connecting board portion 3a and having a width three times or more that of the connecting board portion 3a;
3b, and a long hole 3 in the vertical direction is formed in the side plate parts 3b, 3b.
c, 3c are formed.

Then, the mounting members 3 are applied to the toothed belt member 4 at predetermined intervals, the block member 2 is placed on the felt member 5 in a corresponding manner, and then the bolts 7,
7 through the elongated hole 3c and fastening both members 4 and 5, the block member 2 is removably attached to the felt belt 1, and the toothed belt member 4 and the felt member 5 are not separated. are connected like this.

A method of conveying a long object W to be conveyed at high temperature, such as an aluminum molded product, using the felt belt 1 will be explained.

As shown in FIG. 8, during conveyance, the conveyed object W is placed between the block members 2 and 2 of each felt belt 1, in which a plurality of felt belts (for example, about 40 felt belts at a pitch of 1200 mm) are arranged in parallel. The object W to be transported is placed so that the longitudinal direction thereof is perpendicular to the transport direction, and is transported in that state.

[0018] Therefore, the transported object W is cooled during transport, and since it is long, a difference in heat shrinkage occurs, which tends to cause an arch-shaped warp in the front and back direction in the horizontal plane. Since the transported object W is placed between the block members 2, 2, when the transported object W is warped, the transported object W comes into contact with either the front or rear block members 2, 2, and Warping of the transported object W is suppressed, and occurrence of warping of the transported object W is regulated.

Furthermore, since the block member 2 is removable, the cover member 6 can be easily replaced by removing the block member 2.

Further, since the block member 2 supporting the object to be transported is covered with the cover member 6, direct contact between the object to be transported and the cover member 6 is avoided, and the object to be transported is covered with the cover member 6. There is no risk of damage due to contact with 2. Furthermore, since the cover member 6 is made of a heat-resistant felt material, the block member 2 is protected from heat.

[0021] In the above embodiment, the felt belt 1 in which the felt member 5 is bonded to the toothed belt member 4 is explained, but it is also applicable to the case where the felt member 5 is not bonded and is simply laminated. can do. In that case, the toothed belt member 4 and the felt member 5 are connected by connecting the block member 2 and the mounting member 3, and when the felt member 5 is worn out, the felt member can be removed by removing the block member 2. 5 can be easily replaced.

[0022] Furthermore, the present invention can also be applied to a structure in which a flat belt member is used instead of the toothed belt member 4. In that case, as shown in FIG. 9, recesses 12a in the belt width direction are formed in the flat belt member 12 of the felt belt 11 at predetermined intervals over the entire circumference of the belt, and the mounting member 3 is inserted into the recesses 12a. The connecting board portions 3a are engaged with each other.

[0023]

[Effects of the Invention] As described above, the invention as claimed in claim 1 is characterized in that a long object to be transported at a high temperature such as an aluminum molded product is placed between metal members and transported, so that the object to be transported is Even if the transported object tries to warp in the front-rear direction in the horizontal plane due to the difference in thermal contraction, the transported object contacts the metal member and the warp is suppressed by the metal member, and the occurrence of warpage of the transported object during transport is suppressed. Ru.

According to the second aspect of the invention, the cover member made of the same material as the felt member avoids direct contact between the metal member and the object to be transported, so that the object to be transported is not damaged by the metal member. The metal parts are protected from heat.
