[Problem that the idea aims to solve]

In the former case of the above conventional technology, the opening of the film wrapping the product is Because it is located on the side of the film opening device and film feeding chain, Due to location constraints, tall items cannot be packaged in an upright position. There was a problem. Furthermore, the conventional packaging equipment mentioned above cannot be packaged while standing upright; Used for film packaging of products that cannot be folded or that cannot be wrapped if folded. The problem was that I couldn't do it. Moreover, the film feeder that feeds out the bi-folded film The base end of the unloading chain is connected to the film roller between the product conveyance belt and the product unloading belt. It cannot be placed on the side of the belt, that is, in a position that overlaps with the product conveyance belt. There are structural constraints that prevent the film from being fed out during film feeding. There is a problem in that cracks are likely to occur at the welded corners. This is a product conveyor belt The two-fold film is fed out in parallel with the product conveyor belt in between. Due to the structure, the film feeding device cannot cut into the film in the area where the It is from. Therefore, the cut ends of the welded film should be rolled up. It must be pulled with a pull-out chain, and in order to prevent cracks at the corners of the welded part, a filter is applied. It is necessary to keep the tension on the arm to a minimum. Therefore, the film may not come into contact with the equipment. The film must be fed out without touching the film, and the feeding angle of the film is limited. The disadvantage is that the amount of film required for packaging increases and the bag manufacturing size increases. There was a point.

[0005] Also, in the latter case of the above conventional technology, only bags of a certain fixed size are used. Moreover, if you package a box-shaped product to the desired size according to the product, Although it can be said that it is not a device, it is not versatile.

[0006] This idea was made in view of the problems of the conventional technology mentioned above. Tall products can be reliably packaged while standing upright, using less space. An object of the present invention is to provide a packaging device that can efficiently package products at a speed.

[0007]

[Means to solve the problem]

This idea consists of a product conveyor belt that sends products in, and a product delivery bell that sends products out. In a packaging device that wraps products using a bi-fold film, this The film openings face each other at almost right angles to the belt surface across the product conveyance belt. A device is installed on the film feeding side of this film opening device to handle the above products. Feeds the film in the film traveling direction from above the conveyor belt to the product unloading belt. A device is installed, and an upper The sealing device that cuts and welds the opening of the film is attached to the bell of the product delivery belt mentioned above. This is a packaging device installed in a plane that is approximately perpendicular to the top surface and parallel to the product delivery direction.

[0008]

[Effect]

The packaging device of this invention connects the film opening device almost directly to the product conveyance belt. The film feeding device was installed at the corner and was placed above the product conveyance belt, making it very high. Even tall products can be reliably and neatly wrapped in film while standing upright. The film can be fed out reliably and the bag making size can be reduced. .
