摘要

摘要:介绍了一种自动吸烟机及改进后的相关设备。自动部分包括一个“串切断”技术,可以立即准确地停止香烟的雾化动作。这是通过一个电子序列来实现的,该序列使三通电磁阀失效,并将烟雾排到注射器处的空气中。螺线管失活是通过使用微动开关和继电器实现的。一个自动计数装置记录了每个端口上香烟的数量。计数器由一个信号发生器以每秒5个脉冲的速度脉冲。发电机由一个2秒凸轮和微型开关激活,连接到4秒凸轮上,使吸烟机循环。恒定的喷射器体积和喷射器持续时间是通过使用单独的注射器偏心凸轮,允许精确的体积调整在每个端口和电磁阀,作为进气和排气阀,并提供积极的行动。电磁阀由2秒凸轮和微动开关激活,与注射器的向下冲程同步。通过机器的变速控制齿轮驱动电机精确获得2.0 AA±0.2秒的抽气。这一特点产生了一个稳定的体积和持续时间,无论香烟的阻力。通过本文中描述的自动化发展,以前在O'Keeffe和Lieser机器上获得的精度水平降低了三分之一。

The Design of an Automated Syringe-Type Smoking Machine
Abstract An automated smoking machine, and improved associated equipment, has been described. The automatic portion consists of a "string cut-off" technique which instantly and accurately stops the puffing action on cigarettes. This is achieved by an electronic sequence that deactivates three-way solenoid valves and vents the smoking train to the air at the syringe. Solenoid deactivation is achieved through the use of microswitches and relays. An automatic puff-counting unit records the number of puffs taken on the cigarettes on each port. The counters are pulsed by a signal generator set for 5 pulses per second. The generator is activated by a 2-second cam and microswitch attached to the 4-second cam that cycles the smoking machine. Constant puff volume and puff duration are maintained by use of individual syringe eccentric cams that allow precise volume adjustment on each port and solenoid valves that serve as intake and exhaust valves and provide positive action. The solenoid valves are activated by the 2-second cam and microswitch that is synchronized with the puffing downstroke of the syringe. The 2.0 AA± 0.2-second puff is precisely obtained through the machine's variable speed controlled gear driven electric motor. This feature yields a stable volume and duration regardless of the resistance of the cigarettes. The level of precision obtained previously on the O'Keeffe and Lieser machine was reduced by one-third by the automation developments described in this paper.
