Description

  The present invention relates to a picking stand for dry leaf tobacco, and in particular, after removing the tobacco from the dryer, confirming the alignment of the dry leaf, removing defective dry leaves and simultaneously removing foreign matter such as vinyl pieces and thread pieces. The present invention relates to a foreign matter mixing type picking table used at the time of picking work including.

  Conventionally, leaf tobacco is dried by holding a large number of leaves in a needle rack after harvesting, or knitting a leaf with a sewing machine and attaching it to a hanger, and suspending the needle rack or hanger together with a dryer. At this time, in many cases, vinyl pieces and weeds that are commonly called mulch mixed at the time of harvesting, yarn pieces mixed at the time of sewing machine leaf knitting, and the like are simultaneously dried. And after all the drying process is finished, take it out of the dryer and check if the dry leaves are in good order, pull out the problematic leaves and the conspicuous leaves to make the quality even more, vinyl pieces, yarn pieces, weeds, etc. Inspect and remove foreign substances, and pack and store in a compression packing machine after compression packing. In this way, the work of extracting the problematic leaves and the conspicuous leaves to make the quality uniform is called picking, and this work is performed manually on the picking table.

  However, even in a small drying facility, the amount of dry leaves to be processed at one time is 32 for needle racks, 60 for hangers, and 140 to 180 for dry leaves in a common drying area. There is a problem in that it takes time and time, and an accident occurs in which foreign matters such as vinyl pieces, yarn pieces and weeds are mixed in dry leaves.

  In order to solve the above-described problems, a leaf tobacco dry leaf picking table in which a power-driven yarn take-up device is integrally attached to a picking table body has been proposed (see Patent Document 1).
