炭素繊維の製造費の上昇の一因となる。 Conventionally, when processing pitch yarn to produce carbon fiber, as shown in FIG. A tray 5 consisting of a frame 3 and a rod 4 placed on the frame 3 is used, and the rod 4 of the tray 5 is
The pitch yarn bundle 6 is suspended from the tray 5, and the pitch yarn bundle 6 is carried into the infusibility furnace and the firing furnace together with the tray 5. Then, when carrying the tray 5 into the furnace, the base 1 of the tray 5 to be carried is pressed against the base 1 of the preceding tray 5 located in the furnace, and a new tray shaped like a bead is pressed. 5 is carried into the furnace, the preceding tray 5 in the furnace is moved to the furnace exit side, and the tray 5 located on the furnace exit side is carried out of the furnace. By the way, when carrying a new tray 5 into the furnace in this way, if you try to simultaneously move a large number of preceding trays arranged in series in the furnace, the base 1
must apply an extremely large amount of force. In addition, the temperature is 100℃ to 400℃ in the infusibility furnace and 800℃ in the firing furnace.
To process pitch yarn bundles at temperatures ranging from ℃ to 900℃,
The tray 5 itself, including the base 1, must be made of heat-resistant steel. Therefore, in conventional trays, a thick base 1 is used to withstand high temperatures and the force of moving a large number of trays, and it has a considerable weight, making it difficult to transport the trays. It requires an extremely large power source. Moreover, when the tray 5 is used, the base 1 obstructs a uniform gas flow in the furnace, making it difficult to uniformly perform the chemical and thermal treatment on the pitch yarns. However, if such a large number of openings 7 are to be formed in the base 1, thicker material must be used to maintain strength, which increases the manufacturing cost of the base 1. ,
This contributes to the increase in the manufacturing cost of carbon fiber.

くない。 In FIGS. 2 and 3 showing the principle of the present invention, both furnace walls 2
Support members 24 and 25 are attached above 2 and 23, and long movable members 26 and 27 are placed on the support members 24 and 25, respectively. A large number of support members 24 and 25 are provided along the transfer direction A, and the movable members 26 and 27 move in the A direction while being guided by grooves 28 formed in the support members 24 and 25. Recesses 29 are formed at approximately equal intervals on the upper surface of each of the movable members 26 and 27, one end of each of which is positioned within the recesses 29, and a rod 30 serving as a member for suspending a pitch thread is attached to the movable member. It is supported by being bridged between 26 and 27. A pitch yarn bundle 31 is continuously suspended from the rod 30. The interval between the recesses 29 on the upper surfaces of the movable members 26 and 27 is determined by the diameter of the rod 30 to maintain its designed strength and the diameter of the pitch yarn bundle 31 suspended therefrom.
The distance plus the thickness of . If the distance between the rods 30 is too large, the packing density of the pitch yarn bundle 31 will decrease and sufficient processing capacity will not be obtained, which is not preferable.

する。 The lengths of the movable members 26 and 27 are the rod 30 and the rod 30.
It has sufficient bending strength against the entire weight of the yarn bundle 31 suspended in the yarn bundle 31, and has sufficient buckling strength against the load caused by the pile-up conveyance during the series movement of the movable members, which will be described later. , and is determined to facilitate operation when suspending the pitch yarn bundle 31 from the rod 30. Assuming that the movable members 26 and 27 are subsequent movable members, the movable members 26 and 27 are arranged in series with the preceding movable members 32 and 33 and carried into the interior 21, and each of the movable members 26 and 27 is The tips 34, 35 abut the rear ends 36, 37 of the preceding movable members 32, 33, respectively. Therefore, when the movable members 26, 27 are moved in the A direction, the movable members 32, 33 are pushed by the movable members 26, 27 and are also moved in the A direction. During movement, each movable member slides on support members 24, 25 which have means for reducing sliding resistance, for example, means for making line contact with the movable member at desired positions, as required.
このように形成されたピツチ糸搬送装置３８に
おいては、比較的重量が大きい基台を除去し得る

尚、可動部材２６，２７の炉内部２１への搬入
は、人手によつて行つてもよく、また電動機を用
いて機械的に行つてもよい。 In the pitch yarn conveying device 38 formed in this way, since the relatively heavy base can be removed, it is possible to carry the yarn into the interior 21 one after another with a small amount of power. Since the members can be moved to the discharge side at the same time, and in addition, a uniform gas flow can be generated between the pitch yarn bundles,
Uniform chemical and thermal treatments can be applied to pitch yarn.
The movable members 26 and 27 may be carried into the furnace interior 21 manually or mechanically using an electric motor.
ところで、装置３８では、搬送に際して一対の
可動部材２６，２７の移動量が異なり、棒３０が
可動部材２６，２７に対して斜交してピツチ糸束
間に所定の間隔が得られなくなるおそれが生じ
る。 By the way, in the device 38, the amount of movement of the pair of movable members 26, 27 is different during conveyance, and there is a risk that the rod 30 will cross obliquely with respect to the movable members 26, 27, making it impossible to obtain a predetermined interval between the pitch yarn bundles. arise.

有する。 Furthermore, in the device of the present invention, since the pitch thread is suspended on the pitch thread suspension member mounted on a pair of movable members connected by a U-shaped connecting member, the pitch thread is suspended in the furnace. It can be suspended on a pitch string hanging member outside, and
A movable member is placed on the upper part of both side walls of the furnace, and rollers are provided on which the movable member can be moved. A pair of movable members can be introduced into the furnace, and the movable member on which the pitch thread is mounted is moved within the furnace by colliding movement with the preceding movable member,
This movable member can be moved out of the furnace by a subsequent movable member. Therefore, the device of the present invention does not need to provide a means for circulating the pitch thread hanging member in the furnace, and has the advantage that providing such a means does not cause difficulties in maintenance and operation. In addition, since rollers such as nip rollers are not used to supply the pitch thread to the pitch thread suspension member and to take out the pitch thread from the pitch thread suspension member, roller transport is not possible. It has the advantage that even weak pitch yarns can be heat treated.
