As shown in FIGS. 1, 3, and 4, the tube alignment supply unit 1100 is provided with a first frame 1110 and a plurality of tubes cut to a predetermined length by being installed on the first frame 1110. The fast feeder 1120 is a supply device (1) is aligned and sequentially supplied, and the fast feeder 1120 and the tube feeder 1200 to supply the tube is aligned and supplied from the fast feeder 1120 It includes a tube guide 1130 is installed in the second frame 1210 which will be described later of the tube chamfer 1200, the width is adjustable.

The tube guide 1130 is directly mounted to the fast feeder 1120 to be adjusted according to the length of the tube 1 and the first tube guide 1131 and the second frame 1210 is installed on the Like the first tube guide 1131, the second tube guide 1132 is configured to be adjustable according to the length of the tube 1.

Here, the second tube guide 1132 includes a support member 1132a fixed to the second frame 1210, an inclined member 1132b having a constant width fixed to and supported by the support member 1132a, and It includes a tube guide member (1132c) is configured to be adjustable in width on top of the inclined member (1132b) and guide the tube (1) without being separated.

Of course, the first tube guide 1131 and the second tube guide 1132 may be integrally formed.

And the tube chamfering portion 1200 is, as shown in Figure 1, the second frame 1210 and the second frame 1210 installed in a constant width and height, is installed in the second frame 1210 to align the tube at regular intervals to transfer And a tube chamfering unit 1230 installed in the second frame 1210 to automatically chamfer both ends of the tube being transported by the tube transfer unit 1220.

The tube transfer part 1220 is provided on a speed regulating motor 1221 installed in the second frame 1210, a power transmission first chain gear 1221a and a second frame 1210 installed in the speed regulating motor. A chain 1223 which transmits rotational force to the installed power transmission second chain gear 1222, a housing 1224 installed in the second frame 1210 to support the power transmission second chain gear 1222, and A rotation shaft 1225 connected to the power transmission second chain gear 1222 while being supported and rotated by the housing 1224, and a first tube feed chain gear 1226 fixed to rotate synchronously with the rotation shaft 1225; A second tube transfer chain gear 1227 installed at a predetermined distance from the first tube transfer chain gear 1226 in the second frame, the first tube transfer chain gear 1226 and the second tube transfer chain gear 1227 ) And a plurality of transfer blocks 1228a for conveying the tube 1 at regular intervals, Consists of a chain transfer eojin tube 1228 and the tube traverse chain 1228 tube (1) has a top and bottom to prevent the escape when chamfered tube adjustment device 1229 is conveyed by the.

Here, the second frame 1210 is provided with a drop guide member 1211 for guiding the tube which is transferred to the tube transfer chain 1228 and falling to the outer loading portion 1300 (product receiving container).

Therefore, when the speed regulating motor 1221 rotates, the rotational force is transmitted to the rotation shaft 1225 by the chain 1223, and the rotational force of the rotation shaft is transmitted to the first tube transfer chain gear 1226, so that the tube transfer chain 1228 is rotated. ) Rotates to feed the tube.
