单箱多工位烟丝装箱系统缓存装置的设计

Design of Buffer Device in Single-case Multi-station Cut Tobacco Case Filling System

为解决单箱多工位烟丝装箱能力与膨胀烟丝生产线的小流量生产能力不匹配等问题,在装箱系统的纵向和横向往复铺料皮带输送机之间设计增加一个缓存装置。该装置主要由储料槽和皮带输送机组成,在系统正常装箱时,缓存装置作为烟丝通道使用;系统换箱时,皮带输送机上的烟丝暂存在缓存装置上;系统换箱完成时,缓存装置上的烟丝与纵向皮带输送机上的烟丝一起进入横向皮带输送机,进行装箱;当缓存装置上的烟丝完成装箱时,系统回到初始状态。结果表明:改进后的单箱两工位烟丝装箱系统,利用缓存装置实现了单箱单工位装箱,设备结构简单,运行稳定,与两工位装箱系统相比,占地面积减少了50%,设备投资成本减少了50%,在装箱数量均为7箱/h条件下,设备利用率提高了一倍,满足了膨胀烟丝生产线连续装箱的生产需求。

To match the capacity of single-case multi-station cut tobacco case filling system with that of tobacco expansion system, a buffer device was installed between the longitudinal and transverse reciprocating tobacco spreading belt conveyors in the case filling system. The device was mainly composed of a cut tobacco storing trough and a belt conveyor. When case filling was in operation, the buffer device worked as a tobacco passage; the tobacco on the belt conveyor was temporarily stored in the buffer device when the case filling was completed; the tobacco in the buffer device and that on the longitudinal belt conveyor was directed to the horizontal belt conveyor until the filled case was removed and an empty case was in place, then started a filling cycle again. The results showed that case filling of single-case single-station was realized via a buffer device, the new system was simple in structure and smooth in running. Comparing with the original one, new system had the same output of 7 case/hour, but cut the site area and capital investment by 50%.
