5 to 10, the housing 60 having the movable rod 64 is firmly installed on the upper part of the table 9, and the stepped connection is formed on the upper part of the housing 60. As shown in FIGS. A bracket 62 is installed so that the lower ends of the pair of arms 61 are hinged to both ends of the lower side of the connecting bracket 62.

Lower rods 73 of the deployment means 70 are hinged to both upper ends of the connection brackets 62 installed on the housing 60, and the upper rods 72 of the deployment means 70 are both sides. The hinge 61 is formed inside the arm 61.

The upper rod 72 and the lower rod 73 of the deployment means 70 are integrally formed by the connector 71, and the movable rod 74 is hinged between the connector 71 and the upper end of the movable rod 64. As the movable rod 64 is elevated, the pair of arms 61 are expanded or folded by the deployment means 70.

The moving rod 64 installed in the longitudinal direction of the housing 60 is lifted by a drive link 21 operated by a cam 14 of the drive shaft 13, which will be described in more detail. The upper support bracket 20 is installed on the lower surface of the) so that the upper end of the drive link 21 forms a hinge coupling by the drive hinge shaft 18, and the lower support bracket 30 is installed on the upper surface of the support plate 15. The central portion of the driven link 31 is hinged by the driven hinge shaft 19.

In the drive link 21, a drive roller 22 contacting the cam 14 of the drive shaft 13 is installed between the upper and lower ends of the drive link 21, so that the drive link is driven by the cam 14 of the drive shaft 13. 21 is moved clockwise.

As described above, between the lower end of the drive link 21 and the lower end of the driven link 31, which are moved clockwise in the drawing by the cam 14 of the drive shaft 13, the pivot bolts 51 and 52 and the hexagon are moved to both sides. A straight rod 50 made of a rod 53 is installed so that the driving force of the driving link 21 is transmitted to the driven link 31 so that the driven link 31 also moves clockwise.

The upper end of the driven link 31 is provided with a "c" shaped bracket 32 provided with a pair of rollers 33 inward, and the roller 33 of the "c" shaped bracket 32 is a housing ( The hook bracket 63 is installed at the lower end of the movable rod 64 which is installed and lifted at 60, and is coupled to the hook bracket 63 of the movable rod 64, so that the driven link 31 is actuated. The movable rod 64 of the 60 is elevated, and as the movable rod 64 is elevated, the deployment means 70 provided between the upper end of the movable rod 64 and the stepped connection bracket 62 installed on the upper portion of the housing 60. ), The pair of arms 61 are extended or folded.

That is, when the drive shaft 13 is rotated so that the drive roller 22 of the drive link 21 deviates from the cam 14, the drive tension is installed at the lower end of the drive link 21 and the lower end of the driven link 31. The driving link 21 and the driven link 31 are moved counterclockwise in the drawing by the tension of the spring 24 and the driven tension spring 34.

At this time, since the roller 33 of the “c” shaped bracket 32 of the driven link 31 is hung on the hook bracket 63 installed at the lower end of the movable rod 64, the movable rod 64 is moved as shown by an arrow. The connecting rod 71 of which the movable rod 74 of the deployment means 70 in which the upper end and the one end of the movable rod 64 hinge-engages together becomes the upper and lower rods 72 and 73 to move.

The other arm 61 forming a vertical state is a state in which the glass tube 11 is supplied to the heating exhaust device 5 in a vertical state (see Example 6).

When the drive shaft 13 is rotated in the above state and the cam 14 pushes the drive roller 22 of the drive link 21, the drive link 21 is hinged to the upper support bracket 20 at the upper end thereof. Therefore, the lower end of the drive link 21 is moved to the left side (clockwise) in the drawing, and the driven link 31 is driven by a straight rod 50 pivotally coupled to the lower end of the drive link 21. ) As the rotation axis is moved in the same manner as the drive link 21, the "c" shaped bracket 32 of the driven link 31 is to push the moving rod (64).

When the movable rod 64 exits from the housing 60 to the upper portion, that is, the movable rod 64 is moved upward, the pair of arms 61 which are extended at right angles are folded in the same direction as the movable rod 64. At this time, the driven link 31 which pushes the movable rod 64 operates the motion detection sensor 42 installed in the vertical bracket 40 to rotate the rotation means 80 by the electric signal generated from the motion detection sensor 42. By actuating the expansion and contraction cylinder 83 of the regenerative gear 82 is a linear movement.

At this time, since the pinion gear 81 installed at the lower end of the housing 60 including the deployment means 70 is engaged with the leg gear 82, the housing 60 is rotated as the leg gear 82 linearly moves. A damper (not shown in the figure) is installed on the side of the recreation gear 82 to control the movement distance of the recreation gear 82 such that the housing 60 is rotated 180 degrees. The arm 61 on which the existing glass tube 11 is mounted is rotated to the heating exhaust device 5 side, and the arm 61 which supplied the glass tube 11 to the heating exhaust device 5 is rotated to the conveying conveyor a side. (See example 7).

Here, the lifting distance of the moving rod 64 is adjusted by the length of the straight rod 50 installed between the lower end of the drive link 21 and the lower end of the driven link 31, which will be described, the straight rod 50 When the hexagonal bar 53 is rotated in the clockwise direction, both ends of the pivot bolts 51 and 52 are tightened with the hexagonal bar 53 and the length of the movable bar 64 is shortened because the length thereof is shortened. On the contrary, when the hexagon bar 53 is rotated counterclockwise, the pivot bolts 51 and 52 at both ends thereof come out of the hexagon bar 53 so that the length of the movable rod 64 is increased. It will be longer.

As described above, by adjusting the lifting distance of the moving rod 64 according to the length of the straight rod 50, a pair of arms 61 hinged to the upper part of the housing 60 can be adjusted to rotate 45 °. The pair of arms 61 is to form a right angle to transfer the glass tube 11 of the horizontal state mounted on the conveying conveyor (a) in a vertical state.

 As described above, the present invention is illustrated in FIGS. 5 to 10, while the driving link 21 and the driven link 31 are operated by the cam 14 of the drive shaft 13 while the moving rod of the housing 60 is operated. (64) to operate the deployment means 70 and the rotating means (80) installed on the pair of arms (61) interlocked, one arm (61) while the deployed pair of arms (61) moves 45 ° The clamping part 12 of the ()) attaches the glass tube 11 mounted on the conveying conveyor (a), and at the same time, the other arm 61 attaches the glass tube 11 to the heating exhaust device 5. By supplying, the conveying time of the glass tube 11 can be reduced to 1/2 to improve workability, and the glass tube conveyed by absorbing the vibration of the driven link 31 by the damper 41 installed on the vertical bracket 40. (11) of the cold cathode fluorescent lamp produced by minimizing the vibration to improve the reliability of the work, and can transport the longer glass tube It is effective to diversify the standard.
