1. Technical Field
The present invention relates to a bagging apparatus for feeding an article to be bagged into a bag opened by a bag opening means, thereby bagging the article.
2. Description of the Prior Art
A bagging apparatus constructed such that an article to be bagged is fed into a bag opened by a bag opening means, has been already proposed.
For instance, the apparatus which applicant proposed (Japanese Patent Application No. 130,836/1991) is shown in FIG. 10. In this apparatus, a plastic bag conveyed is opened by a suction opening means 15 as disclosed, for instance, in Japanese Patent Publication No. 39,929/1989. Then, a bellows plate 23 is caused to pass into the plastic bag opened, and it inflates the bag in the form of a streamer. By putting a chuck 30 into the plastic bag, the bag is held expanded to the maximum degree by the chuck 30.
Into the plastic bag whose opening has been expanded as mentioned above, an article to be bagged is fed by a pushing means 33 which moves attached on a chain 32. However, this apparatus of the prior art is somewhat complicated in structure and lacks durability because it has a plurality of the pushing means 33 attached on the chain 32.
