(後述の実施例参照)。2. Description of the Related Art For example, a ductile cast iron pipe (straight pipe) manufactured by centrifugal casting is commercialized through an annealing process under predetermined conditions after casting. In the annealing, usually, in a rollover type continuous heating annealing furnace, cast iron pipes are arranged in parallel at a constant pitch on a plurality of skid rails laid with a gentle ascending gradient in the transport direction, and the receiving end face is furnace wall. In a state where they are aligned on a line keeping a predetermined distance from, while pressing and rolling two places of each tube with claws protruding at a fixed pitch from an endless double conveyor parallel to the skid rail, at a predetermined speed It is carried out by passing through an annealing furnace (see Examples described later).

ゆる蛇行の状態が現出する。At this time, the cast iron pipe is transported while rotating on the skid rail. However, the cast iron pipe in an as-cast state is not always a perfect circle and has a slight bending in the length direction. During this, the end of the cast iron pipe comes in and out, and a so-called meandering state appears.

It could lead to an accident that could result in For this reason, side pushers are installed at several places on both sides of the furnace, and the press rods are used to press the end face (receiving side or insertion side) of the cast iron pipe to correct the position.

4m for 5mm pipe and 100mm diameter pipe, 150m diameter
m is 5m, and the diameter is 100mm for gas pipe.
The above is 5 m. If these 4m pipes and 5m pipes are separately annealed in a single lot, there is no problem. However, if it corresponds to each product supplied from a plurality of casting machines, and if the annealing furnace is used effectively, Annealing of mixed lots of 4m pipe and 5m pipe is inevitable.

行現象を防止している。In the case where the 4m pipe and the 5m pipe are mixed, if the receiving ends are aligned, 1m enters and exits at the insertion end, but conventionally, it is necessary to correct the position of either pipe having the same stroke and a pipe length difference of 1m. There is no effective side pusher that can be applied, and the worker pushes or pulls the pipe with a hook or the like while visually checking the position of the receiving end from the manhole provided on the furnace wall, By correcting the position, the meandering phenomenon is prevented.
【0007】この焼鈍炉は高温下にあり、その高温下で

改善が望まれている。This annealing furnace is under a high temperature, and the position correction of the cast iron pipe by the operator under the high temperature is a severe operation.
Improvement is desired.

る。Here, a length detecting means for a cast iron pipe is provided,
A side pusher mechanism that detects the length of each tube and selects and presses a stroke according to the detected length is conceivable, but it requires operation of a large-scale facility and a furnace exposed to high temperatures. However, there is also a problem in terms of maintenance.

きるサイドプッシャーを提供することを課題とする。In view of the above, the present invention provides a roll-type continuous heating furnace in which a plurality of pipes having different lengths, such as a 4 m pipe and a 5 m pipe, are conveyed in a mixed manner, without using a length detecting means. It is an object of the present invention to provide a side pusher that can accurately correct the position of any tube with the same stroke.

移動エリアから退去するようにしたのである。In order to solve the above-mentioned problems, the present invention focuses on the fact that the shortest pipe requires the longest pressing stroke, and the progress of the side pusher pressing rod is determined. The shortest tube is pressed to correct the stroke, and a fixed stroke is applied.A plate for pressing each end of the tube with a different length is attached to the pressing rod, and the pressing plate is applied to the tube end only for the tube in charge of itself. They came in contact with each other and moved out of the moving area.

The shift detection may be performed by a person or a sensor. In the course of the pressing rod, each pressing plate corrects the position by pressing the pipe end only for the pipe of the length that it is responsible for. For this reason, even if tubes of different lengths are moving together, the position of the tubes corresponding to them is corrected by one stroke of the pressing rod.

る。DESCRIPTION OF THE PREFERRED EMBODIMENTS The above-mentioned embodiment of mounting each pressing plate on a pressing rod is such that each pressing plate is positioned at a different length interval of a pipe having a different length in the axial direction of the pressing rod. When the rod advances the above-mentioned constant stroke, a pressing plate abutting on the side surface of each pipe moving in parallel is attached to the pressing rod so as to be rotatable around its axis. It is possible to adopt a configuration in which, when it is in contact with the end and is in contact with the tube side surface, it is pushed to rotate and retreat.

い。According to this structure, each pressing plate rotates and retreats in accordance with the movement of the tube by contacting the tube not in charge of itself with the side of the tube, so that there is no obstacle to the movement of the tube.
If the pipe has passed, it returns to a state where its own weight can press its own pipe end. The retreat of the pressing plate by this configuration is mechanical, the structure is simple, and there are few failures.
