Abstract

A bag making and packaging machine forms a first transverse seal portion in a packaging material formed in a tubular shape, fills the packaging material with articles, thereafter further forms a second transverse seal portion to make a bag, and allows the bag to fall, and is equipped with a vibrating mechanism. The first transverse seal portion is formed in a direction perpendicular to a conveyance direction of the packaging material. The vibrating mechanism tilts the packaging material to an outer side of a fall path of the bag and vibrates the packaging material after the packaging material has been filled with the articles and before the second transverse seal portion is formed.

First claim

The invention claimed is:

1. A bag making and packaging machine comprising:
a conveyance mechanism for conveying a packaging material in a conveyance direction, the conveyance direction extending vertically downward below the conveyance mechanism defining a fall path of the packaging material that coincides with the conveyance direction, the fall path being further defined as a path along which the packaging material moves vertically downward in the conveyance direction;
a tube formation mechanism for forming the packaging material into a tubular shape;
a transverse seal formation mechanism for forming a first transverse seal portion at the packaging material before the packaging material is filled with articles, and forming a second transverse seal portion in the packaging material after the packaging material is filled with the articles, thereby forming a bag, and
a vibrating mechanism including:
a pushing member for pushing the packaging material, and
a vibration applying member for applying vibration to the packaging material;
the vibrating mechanism is movable between two arrangements whereby
a first arrangement includes the pushing member pushing the packaging material in a direction transverse to the conveyance direction such that the packaging material is at least partially pushed out of the fall path, and the vibration applying member applies vibration to the packaging material; and
a second arrangement includes the pushing member being moved away from the packaging material, with the packaging material being spaced apart from the vibration applying member, allowing the bag to fall freely down the fall path.

2. The bag making and packaging machine according to claim 1 , further comprising
a longitudinal sealing mechanism that forms the packaging material into a tubular shape by heat-sealing both width direction sides of the packaging material and
the transverse seal formation mechanism heat sealing the tubular packaging material in a direction transverse to the conveyance direction of the packaging material.

3. The bag making and packaging machine according to claim 1 , wherein
the vibrating mechanism includes
a rotating brush that is located on a first side of the fall path and
a pushing member that is located on a second side of the fall path opposite the first side and
the pushing member is configured to move the packaging material in the horizontal direction toward the rotating brush and into contact with the rotating brush.

4. The bag making and packaging machine according to claim 3 , wherein
the pushing member has a contact section that contacts the packaging material,
the contact section contacts the packaging material at a location adjacent to the first transverse seal portion and tilts the packaging material adjacent to the first transverse seal portion toward the first position prior to the second transverse seal portion being formed, and
the rotating brush contacts and imparts vibration to the packaging material adjacent to the first transverse seal portion.

5. The bag making and packaging machine according to claim 3 , wherein the rotating brush has first sections including bristles of a first length and second sections including bristles of a second length longer than the first length.

6. The bag making and packaging machine according to claim 3 , wherein the rotating brush rotates in a direction such that contact with the packaging material is in a direction opposite to the conveyance direction.

7. The bag making and packaging machine according to claim 2 , wherein the vibrating mechanism includes
a rotating brush that is located in a first position located on a first side of the fall path and
a pushing member that is located in a second position located on a second side of the fall path opposite the first position and
the pushing member moves the packaging material in the horizontal direction toward the rotating brush and into contact with the rotating brush.

8. The bag making and packaging machine according to claim 7 , wherein
the pushing member has a contact section that contacts the packaging material,
the contact section contacts the packaging material at a location adjacent to the first transverse seal portion and tilts the packaging material adjacent to the first transverse seal portion toward the first position prior to the second transverse seal portion being formed, and
the rotating brush contacts and imparts vibration to the packaging material adjacent to the first transverse seal portion.

9. The bag making and packaging machine according to claim 4 , wherein the rotating brush has first sections including bristles of a first length and second sections including bristles of a second length longer than the first length.

10. The bag making and packaging machine according to claim 4 , wherein the rotating brush rotates in a direction such that contact with the packaging material is in a direction opposite to the conveyance direction.

11. The bag making and packaging machine according to claim 5 , wherein the rotating brush rotates in a direction such that contact with the packaging material is in a direction opposite to the conveyance direction.

12. A bag making and packaging machine comprising
a conveyance mechanism for conveying a packaging material in a conveyance direction, the conveyance direction extending vertically downward below the conveyance mechanism defining a fall path of the packaging material that coincides with the conveyance direction, the fall path being further defined as a path along which the packaging material moves vertically downward in the conveyance direction;
a transverse seal formation mechanism configured to form a first transverse seal portion in the packaging material, the first transverse seal portion being transverse to conveyance direction of the packaging material, and
a vibrating mechanism located downstream from the transverse seal formation mechanism relative to the conveyance direction of the packaging material, the vibrating mechanism including:
a pushing member for pushing the packaging material, and
a vibration applying member for applying vibration to the packaging material;
the vibrating mechanism is movable between two arrangements whereby
a first arrangement includes the pushing member pushing the packaging material in a direction transverse to the conveyance direction such that the packaging material is at least partially pushed out of the fall path, and the vibration applying member applies vibration to the packaging material; and
a second arrangement includes the pushing member being moved away from the packaging material, with the packaging material being spaced apart from the vibration applying member, allowing the bag to fall freely down the fall path being.

13. The bag making and packaging machine according to claim 12 , further comprising
a longitudinal sealing mechanism that forms the packaging material into a tubular shape by heat-sealing both width direction sides of the packaging material and
the transverse seal formation sealing mechanism heat sealing the tubular packaging material forming a sealed place and further includes a cutting mechanism that cuts the sealed place to form the first transverse seal portion of a first bag and the second transverse seal portion of a second bag.

14. The bag making and packaging machine according to claim 12 , wherein
the vibrating applying member is a rotating brush that is located on a first side of the fall path and
the pushing member is located on a second side of the fall path opposite the first side and
the pushing member is configured to move the packa
