The supply unit 10 is provided on one side of the apparatus of the present embodiment and is configured to supply the tube T supplied by the tube supply apparatus (not shown) separately provided to the support unit 20.

The supply unit 10 may be configured in various ways, but in this embodiment, a configuration capable of supplying the tubes T one by one is applied. As an example, the supply unit 10 includes a guide 11, a stopper 12, and a cylinder 13 so as to stably supply the tubes T one by one.

FIG. 3 is an operation state diagram of the tube supply unit for stopping the tube so as to supply the tubes continuously fed one by one, and FIG. 4 is an operation state diagram of the tube supply unit in the state of supplying one tube.

Referring to these drawings, the guide 11 is formed as an inclined cylinder which is formed to be inclined downward toward the support 20. Therefore, the tube T supply before the guide 11 is pushed by the pushing force by a belt conveyor (not shown) or other devices (not shown), and the tube T is fed downward through the guide 11. At this time, the inner surface of the guide 11 and the outer surface of the tube (T) is a friction force to the extent that does not interfere with the progress of the tube (T).

The smaller the frictional force, the faster the tube T escapes from the guide 11 and the faster the tube T can be fed.

The stopper 12 is mounted to the front of the guide 11 as a hinge 14 has a structure that can rotate around the hinge (14). In addition, the stopper 12 has a vertical portion 12a facing the front of the guide 11 and a horizontal portion 12b connected at right angles thereto.

The support plates 21 are configured to support the tube T or feed the insert 50 as necessary. To this end, the elastic members 22 apply elastic force to the support plates 21 to maintain the horizontal portions 21a of the support plates 21 in a horizontal state.

At this time, in order to prevent the support plates 21 from being rotated beyond the horizontal state and to prevent the tube T from being rotated outward, the stoppers 24 are provided on the horizontal parts 21a as an example.

In addition, when the support plate 21 lowers the tube T to the inserting portion 50 by the operation of the lowering portion 40, the inclined portions of both sides are opened to both sides while overcoming the elastic force of the elastic members 22. The lowering of the tube T is possible between 21b.

In addition, the support 20 includes a vertical plate 25 opposite the supply 10 of the support plates 21. The vertical plate 25 stops the tube T supplied by sliding over the supporting plates 21 so as not to exceed a predetermined range on the supporting plates 21.

The lower part 40 includes a lower-adsorption block 41 provided above the support part 20, and a cylinder 42 provided in a vertical direction and elastically acting thereon.

The down-suction block 41 has a circular groove 41a corresponding to the circular outer circumferential surface of the tube T on its lower surface. The circular groove 41a makes it possible to stably lower the tube T by widening the contact area between the drop-adsorbing block 41 and the tube T when the tube T is lowered.

In addition, the down-suction block 41 is provided with a plurality of vacuum holes 41b to exert a negative pressure on the tube T in close contact with the circular groove 41a. The negative pressure applied from the outside is applied or deactivated to the vacuum holes 41b.

That is, the lower-adsorption block 41 applies negative pressure to the vacuum holes 41b when the tube T lowers so that the tube T does not rotate during the lowering (process between FIGS. 8 and 8 to 9), When the lowering is completed (Fig. 9), the negative pressure acting on the vacuum holes 41b is released to prevent the negative pressure from acting on the tube T so that the pressure is smoothly separated from the tube T during the rising (Fig. 9 to Fig. 8). .

Further, the down-suction block 41 is provided with an inclined surface 41c at the bottom thereof toward the supply portion 10 side. This inclined surface 41c prevents mutual interference between the tube T and the down-suction block 41 when the tube T is supplied between the down-suction block 41 and the support 20.
