A combination weighing device () performs combination weighing of at least two different articles, weighing hoppers () and booster hoppers () are divided into at least two groups on the basis of types of the articles, a controller () sets each of the groups to either a first mode or a second mode, in the group set to the first mode, the articles retained in the weighing hopper () are discharged to a receiver () via the booster hopper (), and in the group set to the second mode, the articles retained in the weighing hopper () are discharged to either the booster hopper () or the receiver ().

Combination weighing device with multiple hoppers and modes

A bag-making and packaging apparatus creates one product per cycle by packaging articles in a bag made from a film. The bag-making and packaging apparatus includes a longitudinal sealing mechanism, a guide, an article sensor, a transverse sealing mechanism, a cutting mechanism, and a prediction unit. The guide guides the articles which fall from above into a film tube. The transverse sealing mechanism forms a transversely sealed part in the film tube with each cycle. The cutting mechanism cuts the film tube in the transversely sealed part with each cycle. The prediction unit predicts whether or not jamming of the articles could occur in the transverse sealing mechanism on the basis of an output of the article sensor with each cycle. When the prediction unit has predicted that the jamming could occur in a certain cycle, the cutting mechanism does not cut the film tube in the certain cycle.
