Abstract

A bagmaking and packaging apparatus forms a sheet-form film into a tubular shape around a tube, which tubular film is transversely sealed after product is introduced therein. The bagmaking and packaging apparatus includes multiple upright support posts that form a frame. The support posts include a first support post group disposed on one side in the left and right direction and a second support post group disposed on the other side. A first support post disposed foremost in the first support post group extends from a low position to a position higher than the transverse sealing mechanism and is disposed forward of a center O of the tube. A second support post disposed foremost in the second support post group extends from a low position to a position higher than the transverse sealing mechanism and is disposed rearward of the center of the tube.

First claim

The invention claimed is:

1. A bagmaking and packaging apparatus comprising
a film supply unit disposed in a rear portion of the apparatus and configured to supply sheet-form film;
a former mechanism including a former and a tube and being disposed forward of the film supply unit, the former mechanism configured to form in a tubular shape the sheet-form film supplied from the film supply unit,
a transverse sealing mechanism configured to transversely seal the tubular film in which a product being supplied from above; and
a plurality of upright support posts that form a frame that surrounds at least part of each of the film supply unit, the former mechanism, and the transverse sealing mechanism,
wherein the support posts include a first support post group including a plurality of the support posts disposed on one lateral side of the bagmaking and packaging apparatus in a left and right direction; and a second support post group including a plurality of the support posts disposed on the other lateral side in the left and right direction,
a first support post disposed foremost among the support posts of the first support post group extends from a low position to a position higher than the transverse sealing mechanism and, when viewed from above, is disposed forward of a center of the tube, and
a second support post disposed foremost among the support posts of the second support post group extends from a low position to a position higher than the transverse sealing mechanism and, when viewed from above, is disposed rearward of the center of the tube.

2. The bagmaking and packaging apparatus of claim 1 , wherein the first support post is disposed forward of the tube.

3. The bagmaking and packaging apparatus of claim 1 , wherein the second support post is disposed rearward of the tube.

4. The bagmaking and packaging apparatus of claim 1 , wherein the first support post supports a member disposed above the former mechanism.

5. The bagmaking and packaging apparatus claim 1 , further comprising a cover that is configured to cover at least a front side of the former mechanism, wherein the first support post supports the cover.

6. The bagmaking and packaging apparatus of claim 1 , wherein the first support post supports a movable member.
