Abstract

PURPOSE:To form a cutout in long material positively so as to improve the cutting accuracy of the long material by providing grip mechanism for gripping the long material, and a cutout part forming blade formed to be approaching/ separating freely in relation to the gripped long material. CONSTITUTION:A glass tube G is positioned below the rotary blade 413 of cutout part forming mechanism 40 by carry-in mechanism 20, and a rotating cylinder 404 is operated to rotate a rotary shaft 402 by 180 deg.. Holding rollers 407 in contact with the narrow width part of a holding cam 406 is thereby brought into contact with the wide width part of the holding cam 406, and holding claws 409 are narrowed at the upper end parts thereof against an opening spring 410, so that the glass tube G is held between the V-grooves of holding parts 411. In this state, a cylinder 428 is operated to rotate a horizontal shaft 425, and also an elevating cam 424 is rotated to lower an elevating body 415. The rotary blade 413 rotated by a motor 419 is lowered to form a cutout in the glass tube G. When the above-mentioned device is moved in the reverse direction, the glass tube G is placed in the free state and carried by cutting mechanism 10 so as to be subjected to cutting.

In this state, the cylinder 428 is operated to rotate the horizontal shaft 425 via the rack 427 and the pinion 426, and the lift cam 424 mounted on the horizontal shaft 425 is rotated, whereby the cam follower 42 is rotated.
3, upper plate 422, lifting shaft 421, lifting body 415
To lower. At this time, by driving the motor 419, the rotary blade 413 rotated via the pulley 418, the belt 417, the pulley 416, and the support shaft 414.
Moves down to form a notch in the upper part of the glass tube G below the rotary blade 413. Then, by the rotation of the elevating cam 424, the cam follower 423, the upper plate 422, the elevating shaft 421, the elevating body 415, and the rotary blade 413 supported by the support shaft 414 are raised by the urging force of the vibration absorbing spring 429. Return to the original standby position. Subsequently, the piston rod 405 of the rotating cylinder 404 is operated to rotate the rotary shaft 402 through 180 ° via the connecting rod 403, and the pair of gripping rollers 407 that have been in contact with the wide portion of the gripping cam 406 until now are moved. The holding cam 406 is brought into contact with the narrow portion. As a result, the pair of gripping claws 409 have their upper ends expanded by the biasing force of the opening spring 410, and the glass tube G held by the pair of gripping portions 411 becomes free.

In this case, both the elastic bodies 106, 108 are attracted to the upper and lower molds 101, 102 by the vacuum suction means 113 via the respective suction holes 112, and the elastic bodies 106, 108 are integrally formed. Since the formed protrusion 110 is fitted in the holes provided in the upper and lower molds 101 and 102, both elastic bodies 106 and 108 are fixed to the predetermined positions of the upper and lower molds 101 and 102 and are not displaced. In this state, the driving mechanism 103 simultaneously closes the upper and lower molds 101 and 102 to bring both elastic bodies 106 and 108 into contact with the outer periphery of the glass tube G, and the vacuum suction means 113 causes the upper and lower elastic bodies 106 and 108 to move up and down. The attraction to the molds 101 and 102 is released. Then, as the pressurization and compression by the upper and lower molds 101, 102 to the elastic bodies 106, 108 becomes stronger, the elastic bodies 10 in which the predetermined gap e has been formed so far are formed.
After the divided surfaces of 6, 108 come into contact with each other, the deformed elastic bodies 106, 108 enter into the notch 109 formed in the side portion of each divided surface and the outer peripheral surface, and the upper and lower molds 101, 1
Both elastic bodies 106 and 108 are filled in 02 without a gap,

At this time, since the elastic bodies 106 and 108 are made of silicon rubber and the surface roughness of the inner surfaces of the elastic bodies 106 and 108 is set to 1.5 S or less, the elastic bodies 106 and 108 have the same surface roughness. The adhesiveness (sticking) to the glass tube G is good, and the glass tube G is pulled left and right smoothly following the expansion of the elastic bodies 106 and 108 in the left-right direction. Also, the elastic bodies 106, 108 of the upper and lower molds 101, 102
Since the surface roughness of the contact surface with is set to 6S or less,
The elastic bodies 106, 108 can slide well in the upper and lower molds 101, 102 and can extend to the left and right.
The inner surface of 02 does not interfere with the movement of the elastic bodies 106 and 108. Further, since the upper and lower molds 101 and 102 are pressed against the elastic bodies 106 and 108 simultaneously from above and below, the deformation amounts of the elastic bodies 106 and 108 are the same and the axis of the glass tube G is always maintained at a constant height. Therefore, it is not necessary to move the loading mechanism 20 and the guide mechanism 30 in the vertical direction at the same time when the upper and lower dies 101 and 102 are compressed and compressed.
