Description

DETAILED DESCRIPTION OF THE INVENTION Purpose of the Invention (Field of Industrial Application) The present invention relates to a packaging machine for fresh food that wraps an item by folding a packaging film, which is spread over a packaging section by a conveying device, onto the item. This invention relates to a supply receiving device that is lifted toward a packaging film of a packaging section with an article loaded thereon transferred by an article supply device.

(Prior art and problems to be solved by the invention) The applicant has developed this type of packaging machine under Japanese Patent Publication No. 2-4445.
The invention has already been provided as the invention described in No. In this packaging machine, a supply pedestal device moves up and down between the article supply device and the packaging section, and the supply pedestal device rises with the article transferred from the article supply device placed thereon.
This product pushes up the packaging film stretched in the packaging section, and the packaging film is first folded from three directions by the rear folding member and both left and right folding members below the product, and then the product in the middle of packaging is carried out by the conveyor belt. At this time, the front folding member in a fixed state folds the packaging film from the front as well, thereby completing the folding operation of the packaging film onto the item. As shown in FIG. 5, the supply receiving device 21 of this packaging machine includes a central placing member 24A and a plurality of placing members 2 disposed behind it.
4B is rotatable in the direction of the arrow B, and mounting members 25 and 26 disposed on both left and right sides of the central mounting member 24A are rotatable in the directions of the arrows A1 and A2, respectively. The reason why each of the mounting members 24A, 24B, 25, and 26 is made rotatable is that the packaging film can be placed on the item by the rear folding member and the left and right folding members in B and A in FIG.
1. When folding in the direction of the A2 arrow, each mounting member 24
This is because the folding members A, 24B, 25, and 26 are tilted to enable the folding operation of the packaging film on the underside of the article. However,
If the rear folding member collides with the left and right placing members 25 and 26, or if both the left and right folding members collide with the rear placing member 24B, the movement of the folding member is blocked and the folding operation cannot be performed. For,
Rear mounting member 24B and left and right mounting members 2
5 and 26, a movement-permissible space S was absolutely necessary. Therefore, the supplies pedestal device 21
When the item rises and pushes up the packaging film of the packaging section, the lower corner of the item corresponding to the movement permissible space S becomes vacant, and the pushing force of the item against the packaging film pushes up both corners of the tray of the item. In some cases, the folding member was bent toward the movement permissible space S, and the folding member collided with the bent portion, causing damage to the tray. Moreover, since the movement permissible space S is absolutely necessary, the mounting members 24B, 25, 26 are
The number of mounting members 24B, 25, 26 is reduced.
In some cases, the stability of the items placed on top of the container deteriorated.
