A contact piece located between the inlet and the outer circumferential shaft is integrally formed at the inner end of the central shaft, and the contact piece is moved when the tube front end portion is in contact with the contact piece, and the contact piece is elastically provided at the inlet and outlet side by a spring. The large diameter portion having a larger diameter portion than the central axis is formed at the inner end of the outer circumferential shaft, the large diameter portion fixes the inlet and outlet on the outer circumference thereof, and the diameter of the large diameter portion is larger than the inner diameter of the inlet and outlet. In addition, the sensing means comprises a photosensor to complete the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 2 is a side view showing a part of the present invention in a cross-sectional state, and FIG. 3 is a front view of the main portion of the tube in an aligned state, and the outside of the frame 110 together with the guide surface 120 horizontally installed inside the frame 110. It comprises an entrance and exit means for entering and exiting the tube 130, a moving means for aligning the provided tube 130, a rotation means and a sensing means. The moving means is the upper and lower guide rods 220 and 221 fixed to the left and right walls 210 and 211 of the frame 110 and the straight cylinder 230 fixed to the intermediate position of both guide rods 220 and 221. And a body 260 having upper and lower guide holes 250 fixed to the cylinder rod 240 of the straight cylinder 230.

The rotating means is fixed to the body 260 and the rotary cylinder 320 having a timing belt pulley 310, the shaft 350 is attached to the body 260 and the inlet and outlet 330 and the timing belt pulley 340 is installed at both ends. ), And a timing belt 360 connecting the two puries 310 and 340. The sensing means is installed near the rear end of the shaft 350.

The straight cylinder 230 constituting the moving means is horizontally installed on the fixed block 231 fixed at right angles to the left wall 210, and a fixed bolt for fixing one end of the tension spring 232 to the lower of the fixed block 231. 233 is fixed, and the other end of the tension spring 232 is fixed to the body 260.

The shaft 350 constituting the rotation means has a conical outer circumference 351 for fixing the inlet and outlet 330 and the timing belt pulley 340 at both ends, and a center united to be movable in the longitudinal direction within the outer circumference 351. Shaft 352. The front part of the outer circumference 351 is bent to have a large diameter to form a large diameter part 355 to form a space, and the front part of the central axis 352 is movable in the large diameter part 355 having the space. And a head-shaped contact piece 353 is elastically coupled to the outer circumferential shaft 351 and the spring 354 is formed. In front of the large diameter portion 355, the tube 130 is rotatable and the entrance and exit 330 having an inner diameter 332 of a diameter smaller than the large diameter portion 355 is fixed. The front surface of the inlet and outlet 330 forms a tapered surface, and the contact piece 353 is in contact with the inner surface of the inlet and outlet 330 due to the difference in diameter between the inner diameter 332 and the large diameter portion 355. In addition, a stop block 331 protruding toward the inner diameter 332 is formed at an upper end of the inlet and outlet 330 to be in contact with the contact piece 353. In this case, the stop block 331 may protrude toward the inner diameter 332 at the lower end of the entrance and exit 330. The photo sensor 400 as a sensing means is configured to operate.

When using the present invention configured as described above, when the tube 130 is supplied through an entry and exit device 140 installed in a loading unit or an unloading unit such as a handler or a marking machine, the arrow “C” and the guide surface 120 are supplied. The tube 130 approaches the inlet and outlet 330 as well. At this time, the body 260 is a state in which the cylinder 230 is operated and the cylinder rod 240 is extended, so that the body 260 is in a standby state at the position "A", and at the same time as the tube 130 is supplied, a control signal (not shown). By the operation of the straight cylinder 230 is stopped by the cylinder rod 240 is returned to its original position, the body 260 is in the "B" position. The cylinder rod 240 is in the original position because the body 260 is pulled by the main force of the tension spring 232.

When the body 260 is moved to the "B" position, the rotary cylinder 320 starts to rotate at a predetermined angle according to another control signal (not shown). Accordingly, the timing belt pulleys 310 and 340 and the timing belt are rotated. The shaft 350 is rotated through the 360. For example, when the rotary cylinder 320 rotates by 180 degrees, the shaft 350 rotates by 360 degrees. As the shaft 350 rotates, the entrance and exit 330 also rotates and the stop block 331 also rotates. At this time, when the front end of the tube 130 supplied in the "C" direction touches the inlet and outlet 330, the front end of the inlet and outlet 330 is tapered and the inner diameter 332 is formed in the center, the end of the tube 130 The inner diameter 332 of the entrance and exit port 330 is rotated. The tube 130 that enters the inner diameter 332 is positioned at the tip of the inner diameter 332 by the guide surface 120, and at the moment when the stop block 321 coincides with the groove at the center of the bottom surface of the tube 130. Positioned and aligned as shown in FIG. 3, the tip of the tube 130 pushes the contact piece 353 through the stop block 331 by the tension of the tension spring 232. The contact piece 363 is in contact with the stop block 331 by the spring 354, the spring 354 is compressed when the tip of the tube 130 pushes the contact piece 353, and accordingly the central axis 352 Pushed behind this. At this time, the central axis 352 is pushed back because it is only movably in the longitudinal direction in the outer circumferential axis 351. When the central axis 352 is pushed back, the photosensor 400 is operated and the rotary cylinder 320 is operated to be the same as the initial position. At the same time, the straight cylinder 230 is operated again to extend the cylinder rod 240. And, while moving the body 260 to the "A" position, the rotary cylinder 320 is operated to be in the initial state located on the top of the stop block 31.

At the same time, the tube 130 aligned is discharged through the entry and exit device 140 to finish the alignment of the tube, and then another tube is provided to continue the alignment as described above. In the alignment process, even when the initial position and the final position of the stop block 331 protrude toward the inner diameter from the upper end of the entrance and exit 330 as shown in FIGS. 2 and 3, the alignment is performed as shown in FIG. When the state protrudes toward the inner diameter from the bottom of 330 is to be aligned as shown in FIG.

The tension spring 232 provides a tension force to move the body 260 to the "B" position, and also stop the tube 130 to be supplied and at the same time the elastic force of the spring 354 applied to the contact piece 353 It provides a tension force to operate the photosensor 400 by overcoming and push back, select the end of the tube 130 has a tension enough to not be damaged by the stop block 331 do. The driving control signals of the cylinders 240 and 320, the photosensor 400 and the entry / exit device 140 used in the present invention are technologies that can be easily controlled by those skilled in the art, and thus detailed descriptions thereof are omitted.

As described above, the present invention comprises a cylinder rod, a body which is moved left and right according to the operation of the cylinder rod, a rotating means fixed to the body and a sensing means, and an entrance and exit means for entering and exiting a tube. The tube supplied to the guide surface through the contact with the tube by the left and right movement of the body by the cylinder, the tube is aligned by the stop block and the aligned tube is confirmed by the photosensor and then the tube is discharged, Automatically aligns the product in the desired direction, improving the productivity of IC products and improving the work efficiency.
