Conventional pipe insertion devices using mechanical force into heat exchangers have been limited to pipes up to about 10 meters in length. There are two types of tube feeding devices: a method in which a cylinder or an endless chain is used to push the rear end of the tube, and a tube feed roller is used to feed the tube.

方を動かすこととなり、大規模な装置となる。 Applying the former method to long pipes on the order of 30 meters may cause the pipe to buckle, while using the latter increases the possibility of dents and other damage caused by pinching the pipe. In particular, when feeding tubes loaded on a pallet or the like, it is necessary to increase the pressing force of the tube feeding rollers to overcome the frictional resistance between the tubes, resulting in an increase in dents and the like. In addition, since the conventional tube feed mechanism and tube support are installed integrally on a common pedestal, alignment of the tube plate hole of the heat exchanger and the tube axis, which requires high precision, can be done by using the heat exchanger or the common pedestal. This results in a large-scale device.

7 and the axis of the tube 1 are roughly aligned within the flexibility of the tube 1. In addition, in order to reduce the frictional resistance when drawing out the tubes, the pallet 21 is tilted as required as will be described later. Here, the guide hardware 6 is inserted into the tip of the tube.

引出しは容易である。(4) The holding roller 8 of the tube feed roller 7 is lowered by the holding cylinder 9 to the position shown by the chain line, and the pipe is sandwiched between the holding roller 8 and the drive roller 10 (see FIG. 2). Next, by starting the roller drive motor 11, the guide metal fitting 6 at the tip of the tube 1 passes through each tube hole 5 of the tube plate 3 and the baffle plate 4 one after another, and the tube insertion progresses. At this time, since the tubes 1 on the pallet 21 side are placed on the bottom plate 20, there is no resistance due to wedge-like interference with the lower tubes, and the tubes can be easily pulled out.
管長の大部分が管孔５に入り、管１の後端が
管送りローラ７を通過し終る少し手前の位置で
駆動モータを停止させる。次に抑えローラ８を
始動前の位置に後退させる。 The drive motor is stopped at a position slightly before most of the pipe length enters the pipe hole 5 and the rear end of the pipe 1 passes through the pipe feed roller 7. Next, the holding roller 8 is moved back to the position before starting.
(5) 進退シリンダ１６によりシリンダ１４を実線

（第３図参照）。(5) The cylinder 14 is advanced to the position shown by the solid line, that is, to the rear of the pipe 1, by the advancing/retracting cylinder 16 (see FIG. 3).
次に、押込みシリンダ１４のプツシユロツド
１５を前進させ、管１の残り部分を押込み、管
末端長さ１ａは一定に揃えられる（第４図参
照）。 Next, the push rod 15 of the push cylinder 14 is advanced to push in the remaining portion of the tube 1, so that the tube end length 1a is made constant (see FIG. 4).
(6) プツシユロツド１５を引込め、特に管リヤー
プツシヤ１４を進退シリンダ１６により始動前

まの状態にしておく。（第２図参照）。(6) Retract the push rod 15, and in particular, move the pipe rear pusher 14 back to the position before starting by using the advancing/retracting cylinder 16, and leave it in that state until the next pipe is inserted. (See Figure 2).
なお、管孔５と管１との軸心合せが終つた後、
送りローラ７により管１をはさんでから管リヤー
プツシヤ１４の後退までの過程（第２図〜第４図

容易である。 In addition, after the axis alignment of the tube hole 5 and the tube 1 is completed,
It is easy to automatically control the process from the time when the tube 1 is pinched by the feed rollers 7 to the retreat of the tube lifter 14 (see FIGS. 2 to 4) in a sequential manner.
また、パレツト２１に納められた１段分の管１
をそう入し尽した場合は、敷板２０を取除くだけ
で次の１段分を直ちに管そう入に供することがで
きる。 In addition, one stage of pipes 1 stored in the pallet 21
When the pipe is completely filled, simply by removing the bottom plate 20, the next stage can be immediately used for pipe insertion.
次に、パレツト２１を管軸方向に傾斜させる効
果について第６図（抵抗値−管移動距離曲線）に
より説明する。 Next, the effect of tilting the pallet 21 in the tube axis direction will be explained with reference to FIG. 6 (resistance value vs. tube movement distance curve).
管そう入推力は多数の管板３、邪ま板４の管孔
５に管１を通すのに必要な推力F1と管１をパレ
ツト２１から引出すのに要する推力F2との合成
であるから、送りローラ７に必要な推力を最小に
するには、推力F2ならびに推力F1を小さくすれ
ばよい。 The input thrust for the tube is the combination of the thrust force F 1 required to pass the tube 1 through the tube holes 5 of the numerous tube sheets 3 and baffle plates 4 and the thrust force F 2 required to pull the tube 1 out of the pallet 21. Therefore, in order to minimize the thrust force required for the feed roller 7, the thrust force F 2 and the thrust force F 1 may be made small.
ここで、推力F1は管１が貫通すべき管孔の数
に比例して増加するが、推力F2はパレツト２１
上の敷板２０と管１との摩擦抵抗を減らせばそれ
だけ小さくすることができるものである。 Here, the thrust force F 1 increases in proportion to the number of pipe holes that the tube 1 must penetrate, but the thrust force F 2
The frictional resistance between the upper floor plate 20 and the pipe 1 can be reduced accordingly.
従つて、パレツト２１を傾斜させることによる
効果は大であることが容易に分る。このようにし
て、推力F2を小さくすれば、管送りローラ７の
管１をはさむ力も必要最小限にすることができ、
管をはさむことによつて圧痕やその他の損傷の生
ずる可能性を大幅に減ずることができる。本考案
の管そう入装置は長尺管を対象としているが短尺
管に適用できることはいうまでもない。 Therefore, it is easy to see that the effect of tilting the pallet 21 is great. In this way, by reducing the thrust F2 , the force of the tube feeding roller 7 to pinch the tube 1 can also be minimized.
By pinching the tube, the potential for dents and other damage can be greatly reduced. Although the pipe inserting device of the present invention is intended for long pipes, it goes without saying that it can also be applied to short pipes.

As mentioned above, the present invention comprises a pipe loading head installed on a pipe loading head frame, a pallet suspension stand placed behind it, and a pallet for loading pipes suspended on the pallet suspension stand. The pallet for loading the pipe can be moved vertically and horizontally with respect to the pipe axis and tilted at any angle in the direction of the pipe axis by means of a positioning mechanism such as a hoist installed on the pallet suspension stand. By stacking the tubes in multiple tiers with floor plates in the pallet, the possibility of indentation or other damage when feeding the tubes using tube feed rollers is greatly reduced.
