Conveyance apparatus

摘要

A conveyance apparatus aligns conveyed packaging bags. In the conveyance apparatus, a thickness measurement part measures the thickness of a packaging bag. A controller infers that the width of the packaging bag has decreased when the thickness of the packaging bag is greater than a reference thickness, and the controller causes a first guide member to move so as to approach a second guide member via a guide drive part. In addition, the controller infers that the width of the packaging bag has increased when the thickness of the packaging bag is less than the reference value, and the controller causes the first guide member to move so as to be distanced from the second guide member via the guide drive part.

1. A conveyance apparatus for adjusting a lateral position of each of a plurality of bags while conveying the plurality of bags, each of the plurality of bags having its own vertical length, horizontal width, and thickness, the conveyance apparatus comprising:
a conveyor having a horizontal conveyance surface configured to move in a conveying direction; guide members located above the conveyor configure to make contact with opposite lateral side parts of each of the plurality of bags in the lateral direction and changing the lateral position of each of the plurality of bags in the lateral direction perpendicular to the conveying direction of the conveyor; a thickness measurement part located upstream in the conveying direction relative to the guide members for measuring the thickness of each of the plurality of bags; and a controller for causing the guide members to move in the lateral direction relative to each of the plurality of bags in response to measurement of the thickness of each of the plurality of bags such that the plurality of bags are moved by the guide members to a linearly aligned orientation downstream of the guide members in the conveying direction, and wherein the controller includes memory storing a correlation map that includes data corresponding to movement amounts of the guide members correlated with the measured thickness of the plurality of bags.
