Additionally, this glass pipe is used for elements such as reed switches and mercury switches, or for lamp strobes, temperature fuses, and the like. This glass pipe has a diameter of 4 mm ~ 2511 + 111 z length 10
A long pipe of about 0.00 to 1300 seconds is cut into lengths of 5 seconds to 40 inches (manufactured).

うな切断装置を用いて切断する方法が知られている。By the way, when trying to cut a large quantity of such glass pipes, since glass pipes are hard and brittle, if you try to bundle a large number of pipes and cut them all at once, it is likely that chips will occur during cutting, and it will be difficult to transport the pipes. , the fixed size is terrible. Conventionally, the methods for cutting a large number of hard and brittle pipes include hardening with resin as shown in Figure 8, and
A method of fixing with a shrinkable tube as shown in the figure, or a method of cutting using a cutting device as shown in Japanese Utility Model No. 119445/1982 are known.

The glass pipe P embedded in the resin R is ri17-i

After bundling several pieces of wood, 19 wood, etc., into a stable polygonal shape when bundled, these glass pipes P are inserted into a heat-shrinkable tube, and hot air is blown onto the heat-shrinkable tube. F is contracted, bundled into a polygonal shape and fixed, and this fixed glass pipe 1] is cut with a grinder 6 or the like.

、切り込み速度を早くできないという問題点があった。In addition, in the method of fixing the glass pipe P with a heat-shrinkable duplex and cutting it, vibration is likely to occur because the fixation is incomplete, and there is a gap between the adjacent glass pipes P, so it is difficult to cut the glass pipe P. Chips tend to occur at the edges. Therefore, there was a problem that the cutting speed could not be increased.

is stored and the two belts 10.12 are wrapped around and held.
Rotate the feeder drum 10 drum 2.3
At the same time, the thin blade grindstone 13 is rotated by the spindle 14. In this case, the outer diameter of the feeder drum 1 is larger than the outer diameter of the thin blade grindstone 13,
And the rotational axis m of the thin blade grindstone 13 is the same as the feeder drum 10.
It is set eccentrically from the axis J by a predetermined amount. As a result, as shown in FIG. 7, the rotating thin blade grindstone 13 is
The plurality of glass pipes 1 stored in both VtMs 2a and 3a of the feeder drum 1 gradually approach while drawing an arcuate trajectory, and successively contact the outer peripheral cutting edge of the thin-blade grindstone 13, and the cutting process is completed. It started for 1m and was finally cut off. At this time, the glass pipe P has two belts 10.1
2 is firmly pressed against the feeder drum 1, and the feeding of the glass pipe P relative to the thin-blade grindstone 13 is circular, so that the cutting angle of the thin-blade grindstone 13 to the glass pipe 1) is gentle. Therefore, the glass pipe P can be cut smoothly and reliably, and no chips will occur on the cut surface.

■The belt 1 is held between the groove 3a and the belt 12.
2 is released at the position where it separates from the lower drum 3, falls downward under its own weight, and is recovered. On the other hand, the remaining part of the glass pipe P is held between the groove 2a of the upper drum 2 and the belt 10, and as the belt 10 leaves the upper drum 2 and moves toward C, it follows the inclination of the upper drum 2.
lll along groove 28! The drum moves downwardly, crossing the gap between both drums 2 and 3, and descending along the groove 3a of the lower drum 3. Then, the lower end surface of the glass pipe P is connected to the stopper 1.
5 (in the case of Figures 3 and 4), or stopper 16
(In the case of FIGS. 5 and 6) The glass pipe P is positioned by each belt 10. It is firmly fixed by being pressed against 2a and 3a. In this state J3, the glass pipe P comes into contact with the thin blade grindstone 13 and is cut in the same way as described above.

を防止できる。As explained above, the present invention provides a cylindrical feeder drum having a concave portion on the outer periphery for storing the workpiece, and a rigid material between the two belts wound around the feeder drum. The belt is provided with a rotation mechanism that holds the feeder drum and the belt and rotates them in synchrony, and a cutting blade for cutting the rigid material is arranged between both belts. The rotation mechanism rotates the feeder drum and the two belts in synchronization, and the cutting blade cuts the workpiece while holding the workpiece between the belts and the feeder drum. Then, one of the belts is removed from the feeder drum to take out the product or cut end, and the remaining stiffened material is held between the other belt and the feeder drum in preparation for the next cutting. It is possible to efficiently cut long workpiece materials, and it is possible to easily separate the cut product or cutting edge from the rigid material, making the cutting process easier, and also prevents chips from occurring in the cut section. It can be prevented.
