Abstract:
A packaging device is configured to implement a packing method that prevents a bridge from being generated inside a chute which supplies goods into a bag with a tube shape. In the packing method, goods dropped from above are accommodated in a chute with a funnel shape. The chute is then lowered while accelerating in a state where a discharge opening of the chute is open, and subsequently movement of the chute is suddenly reversed and the chute is raised so that the goods collected in the chute are discharged into a bag with a tube shape while being accelerated. The packaging device is provided with a cylinder which packs dropped goods into the bag with a tube shape, and the chute is raised and lowered in the cylinder.
Abstract:
A bag making and packaging machine is provided with a feed mechanism, a roll holding portion, a printing mechanism, a former, a longitudinal seal mechanism, a transverse seal mechanism, a cutting mechanism, a first sensor, and a second sensor. The printing mechanism prints information on a film. The former causes the two longitudinal sides of the film to become overlapped. The longitudinal seal mechanism bonds the two longitudinal sides and makes a film tube. The transverse seal mechanism sandwiches and bonds the film tube and makes a transverse seal portion. The cutting mechanism cuts the film tube at the transverse seal portion. The first sensor detects a mark on the film for identifying a cutting position for cutting the film tube. The second sensor detects a mark for specifying a printing position of the film where predetermined information is to be printed.
Abstract:
A bag-making packaging machine includes a bag-producing part, a bag receiving part, and a bottom forming part. The bag-producing part is configured and arranged to transversely seal a tubular packaging material to produce a bag having a top seal part and a bottom seal part formed above and below a product-enclosing main body of the bag. The bag receiving part is configured and arranged to receive and hold the bottom seal part and a part of the main body of the bag, which has been dropped from the bag-producing part. The bottom-forming part is configured and arranged to deform the bag in contact with the bag receiving part to form a bottom portion of the bag into a prescribed shape.
