Four first heads 1 are provided radially around the fulcrum shaft 3, and are rotated by 90 ° each around the fulcrum shaft 3, and are held by guide pins 13 in a transport container 14 flowing on a conveyor 18. The tubes 4 are sequentially supplied just above 12. At this time, the transport container 14 is positioned by a stopper (not shown) so that the condenser 12 is located below the first head 1.
The guide plate 15 also serves as a stopper for the transport container 14. The second positioning head 11 is attached to a lever 16 and opens and closes around a support shaft 17 by opening and closing an air cylinder 24 to position the capacitor 12. Entire conveyor (lever 16, conveyor 18, belt 19, frames 20, 25, slide shaft
26) is moved up and down by a ball screw 27 which is rotated by a motor 28, and is inserted into the condenser 12 having a different length depending on the kind so that the tube 4 does not bite between the insertion plate 5 and the first head 1 when the tube is inserted. In order to set the distance, the height of the conveyor 18 is adjusted so that the distance a between the upper surface of the condenser 12 and the first head 1 is constant. The insertion plate 5 is moved up and down by an air cylinder 9,
Insert the tube 4 into the condenser 12. Height adjustment screw 6
Is for adjusting the insertion distance of the insertion plate 5.

FIG. 6 shows the operation sequence of tube insertion by this device. First, as shown in FIG. 6 (a), the condenser 12 is held coaxially with the first head 1 by the second positioning head 11, and the insertion plate 5 connects the tube 4 to the upper surface of the second positioning head 11. (The first stage). Next, as shown in FIG. 6 (b), the second positioning head 11 is opened, and thereafter, as shown in FIG. 6 (c), the insertion plate 5 is lowered and the tube 4 is completely removed from the condenser 12 (Second stage). In this way, tube insertion is performed by the two-stage operation of the insertion plate 5.

SUMMARY OF THE INVENTION In the above-described conventional technology, the second head 11 holds the capacitor 12 at the time of the first stage of insertion, so the insertion is stopped once, the second head is released, and then the insertion is performed again. Must be performed, the operation becomes complicated, and the speed is increased. Further, as shown in FIG. 5, the positioning head 11 is fixed to the whole conveyor, and its position is always the same with respect to the transport container 14. Therefore, as shown in FIG. 7 (a), in the case of the condenser 12 having a high height, the motor 28 is used to keep the distance a between the first head 1 and the upper surface of the condenser 12 constant.
When the entire conveyor is lowered, the positioning head 11 is positioned below the condenser 12, so that the positioning of the condenser 12 becomes unstable, and the condenser 12 is easily inclined and the insertion of the tube 4 becomes unstable. Also,
When the height of the condenser 12 is low as shown in FIG. 7 (b), the entire conveyor is similarly driven by the motor 28 so that the distance a between the first head 1 and the upper surface of the condenser 12 is constant. Since the positioning head 11 is positioned above the capacitor 12 to raise the position, the positioning of the capacitor 12 is stabilized, so that the insertion can be performed. As described above, it is necessary to replace the positioning head 11 and the lever 16 with the height of the capacitor 12. If the upper end of the capacitor 12 is always positioned as shown in FIG. 8 by replacing the second positioning head 11 and the lever 16, the positional stability of the capacitor 12 is improved. In the case where the height of the capacitor 12 is high as shown in FIG. 8A and the case where the height of the capacitor 12 is low as shown in FIG. And the distance d in the second stage of insertion are different, and it is necessary to switch the distance c in the first stage of insertion and the distance d in the second stage of insertion using the height adjusting screw 6 according to the height of the capacitor 12. Therefore, an object of the present invention is to provide a hollow body insertion device that solves the above-mentioned disadvantages.

Means for Solving the Problems And in order to achieve the above object, the present invention provides a first head for holding a hollow body having a predetermined dimension, and a first head for holding the hollow body held by the first head. Insertion means for detaching from the head and covering the object with a predetermined object; conveying means for supplying the object under the first head; adjusting means for adjusting the height of the conveying means; A second head that is disposed at a fixed distance from the head and positions the object with respect to the first head; and causes the object that is positioned by the second head to contact the first head. Lifting means, and positioning the object conveyed under the first head by the conveying means with respect to the first head by the second head, and then releasing the second head to move the object to the first head by the lifting means. Contact the head of the first, then the first The hollow body insertion device is characterized in that the hollow body held by the head is detached from the first head by an insertion means and covered on an object.

In the above configuration, since the object conveyed under the first head by the conveying means is positioned with respect to the first head by the second head, when the object is brought into contact with the first head by the lifting means later, , The object comes into contact with the first head positioned at a predetermined position,
As a result, when the hollow body held by the first head is detached from the first head by the insertion means and covered with the object, the work is performed smoothly.

Also, by setting the distance of the second head to the first head to be constant and providing an adjusting means for adjusting the height of the conveying means, even when the height of the object is changed,
