Abstract

PURPOSE:To prevent rolling of a bulb thereby improve the working efficiency, by setting the time required for single intermittent operaton of a circular table which rotates intermittently while suspending a linear bulb in the specific range of the inherent vibration of bulb. CONSTITUTION:A rotary spider 2 holding the upper ends of many linear bulbs 8 with chucks 7 is rotated intermittently by a drive mechanism 3 containing a motor 4. Then the bulb 8 is passed through a heating furnace 9 to soften thereafter a supporting rod 14 is operated to support the lower end of the bulb 8 and moved to the position of a molder 10 to wind the bulb 8 around a drum 11. Assuming the moving time required for single intermittent operation of the rptary spider 2 is t1 while the inherent vibration of the bulb 8 is fn, it is set in the range of 9.88fn<=t1<=12.56fn. Consequently the lost time due to the rolling of the bulb 8 is prevented resulting in improvement of productionability.

By the way, in the manufacturing equipment of the groove formation indicated by L, when the above-mentioned valve is transported in a continuous manner, when the intermittent rotation speed of the circular groove indicated by h is increased by 01, the above-mentioned valve swings greatly at the large stop position. Therefore, when supporting the lower end of the valve with the support rod, it is necessary to wait until the swinging has subsided. Therefore, even if the intermittent rotational speed of the circular table is increased unnecessarily, the time required for swinging the valves will be greatly reduced, and this will be a major hindrance to improving productivity. Therefore, in order to improve productivity, it is necessary to set the intermittent rotation speed l of the circular table to the fastest value within the range that does not cause the valve to swing, but this setting may vary depending on the length of the valve. However, it is difficult to set the intermittent rotation speed.

The intermittent rotation speed ω of the rotary spider 2 can be increased to the maximum within the range where the lower end of the valve 8 can be quickly supported by the support 4Si14 and the next intermittent feed can be started.

この結果、実際のトメ動効串が筒まり、生産性の同上を

As a result, a skewer with actual toe movement effect is formed, and productivity can be improved.

Further, the natural frequency fn of the valve 8 is f
Since n = 3 Jf/21, this is a function of the director e of the valve 8. Therefore, even if the length e of the valve 8 is different, the travel time t1 of the rotating spider 2, that is, the optimum intermittent rotation speed can be easily determined based on the length e, and the intermittent rotation speed can be adjusted easily and accurately. It depends on what you do.

Note that this light cut is not only applied to the fissure image 1d shown in Figure 1, but the point is that the bulb 8 is intermittently transported in a holding position, and during this transportation process, this valve is After the valve 8 is heated and softened, the lower end of the valve 8 is further supported by the support rod 14 and can be applied to all manufacturing apparatuses in which intermittent conveyance is carried out.
