【発明の名称】梱包機におけるバンド供給・引締方法及び装置
Document Type and Number:
Japanese Patent JP2857280
Kind Code:
B2
Abstract:
A band feeding and tightening apparatus for a packing machine capable of effectively preventing jamming of a band in band passages during feeding and tightening of the band. A feed touch roller is pressedly contacted through the band with a feed roller rotated at a high speed, to thereby feed the band to a package. When a distal end of the band is gripped, a return touch roller is pressedly contacted through the band with a return roller rotated at a high speed, to thereby draw back the band, resulting in the band being wound around the package. Then, a tension touch roller is pressedly contacted through the band with a tension roller, to thereby tighten the band. Subsequently, an overlapped portion of the band is bonded by welding and a portion of the band wound around the package is cut from the remaining part of the band. A movable guide plate is moved in association with pressing of the feed touch roller to reduce a gap of a feed chute. Also, a tension chute of an arc-like shape is moved in a chord direction of the arc in association with pressing of the tension touch roller, so that a gap of a portion of the tension chute communicating with the return chute is enlarged and that communicating with the feed chute is reduced. Thus, the gap of each of the chutes is varied when feeding and tightening of the band are carried out, to thereby ensure that the band is always delivered from the chute of which the gap is reduced to the chute of which the gap is enlarged to substantially prevent jamming of the band in the band passages.
