Description

In order to overcome the above-mentioned problems and achieve the intended object, a horizontal bag making and filling machine according to the invention of claim 1 is provided:
A pair of seal bodies that move vertically opposite to each other to obtain a package by performing transverse sealing and cutting on the tubular film before and after in the conveyance direction of the article in the tubular film,
A carry-out conveyor disposed on the downstream side of the seal body;
When the side seal is applied with the seal body to form the ear portion before and after the package body, a brazing means for giving a crease to the ear portion;
A rear-ear folding body that moves up and down so as to advance and retreat to an operating position in the conveyance path of the article between the pair of seal bodies and the upstream end of the carry-out conveyor;
A front ear folding body that moves up and down so as to advance and retreat to the operation position in the conveyance path of the article on the downstream side of the operation position of the rear ear folding body by an interval between the front and rear ear portions in one package .
The front and rear ear folding body, characterized in that the ear portions of the front and rear of the front SL operating position to be advanced sealed immediately after the package was configured to bend from the crease.

In the invention according to claim 2, the pair of seal bodies are configured to move to the upstream side after being separated from each other after moving to the downstream side in a state of sandwiching the tubular film,
The rear-ear folding body that folds the rear-side ear portion of the package is configured to advance to the operating position immediately after both seal bodies release the film and move to the downstream side.

In the invention according to claim 3, the cylindrical film has a vertical seal portion formed on the upper surface side, and the front and rear ear folds are advanced from the lower side to the operating position so that the front and rear ear portions are bent upward. It is characterized by comprising.

The invention according to claim 4 is characterized in that the distance between the front and rear ear folds is adjustable.

The invention according to claim 5 is characterized in that the timing at which the front and rear ear folds advance to the operating position is variable.

According to the invention of claim 1, since it is configured such that the bend Ri folded ears before and after a state sandwiching the package from the back and forth around the ear folding body spaced intervals worth of front and rear ear portion, the ear portion It is not necessary to separately provide a member for restricting the package from moving back and forth during the folding, and the configuration can be simplified. Also, before the ears heated and softened by the sealing body regain their initial restoring force, the ears can be folded with the crease portion as a base point, and the front and rear ears are kept folded. A package is obtained. That is, even when a firm material is used as the film, it is possible to manufacture a package that maintains the state in which the ear portion is securely bent.
According to the invention which concerns on Claim 2, the ear | edge part bent by the rear ear | edge folding body immediately after completion | finish of the heating to the film by a sealing body can be hold | maintained in a bending state until temperature falls, The bending state of an ear | edge part Is reliably maintained.
According to the invention which concerns on Claim 3, since an ear | edge part is bend | folded to the surface side in which the vertical seal part in the package was formed, the appearance of the opposite surface side can be made favorable.
According to the invention which concerns on Claim 4, it can respond easily to the size change of a package.
According to the invention which concerns on Claim 5, according to the difference in the length of the front-and-rear ear | edge part, each ear | edge part can be bent at the optimal timing.
