DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging apparatus for successively packaging objects to be packaged in a film while forming the film into a cylindrical shape.

[0002]

2. Description of the Related Art The following automatic packaging apparatus is currently used.

[0003] A film continuously wound in a roll shape is drawn out from a supply unit, and the heat-sealable band-like film drawn out is folded into two in a state of being opened at an upper part, and is conveyed forward by a conveying guide unit. A transport device for transporting the two-folded film is provided, and an opening guide unit for transporting the two-folded film while holding the upper left and right edges of the two-folded film at a predetermined length is provided as a feeding unit, A horizontal sealing device is provided at a predetermined interval from the input section into the film at a predetermined interval, and the upper opening of the film containing the package is closed by polymerization sealing to form a tubular film, and A vertical sealing device for heat-sealing the portion between the objects to be packaged of the tubular film intermittently conveyed by the device, and cutting between the vertical sealing portions It has a configuration provided with a cutting device to separate the objects to be packaged containing packaging bag conveying side connection of the tubular film on the transfer terminal end of the conveying device.

[0004] Further, the articles to be packaged are sequentially placed on the opening guide section of the input section by hand, or the discharge end of a supply device such as a conveyor device faces above the opening guide section.
A configuration is adopted in which the articles to be packaged are automatically dropped and placed on the opening guide section and then thrown in, and the article to be packaged (placed on the opening guide section) is transported together with the folded film. Each of the above-described processes is applied to form a bag.

However, the articles to be packaged are manually supplied in accordance with the intermittent transport of the film so that the articles to be transported are spaced at a predetermined interval, or the supply timing of the supply device is synchronized with the intermittent transport of the transport apparatus. Even if it does in this way, the interval of the to-be-packaged products will vary, and the vertical sealing position and the cutting position will not always be located between the to-be-packaged products, and will be biased to either side, causing trouble in the bag making process. There is a risk.

Therefore, conventionally, a shutter plate for preventing the transport of the packaged object is provided at the loading position so as to be openable and closable so that the shutter plate can be used as a guide when the loading and loading operation is performed, or function as a positioning plate. The package is transported together with the film by opening the shutter plate, and the shutter is opened to control the transport of the film and the opening and closing of the shutter so that the package is transported at regular intervals. Some are configured to be performed.

[0007]

However, if the shutter plate is simply opened and closed as in the prior art, there is a case where a positional shift occurs when the packaged object is supplied to the input section based on the shutter plate. Due to this positional deviation, the interval between the articles to be packaged is not always constant, so that the articles to be packaged may be bitten in the bag making process by the vertical sealing device or the cutting device on the transport side.

According to the present invention, the structure of the shutter plate is further improved, the positioning accuracy is drastically improved by a simple method, the objects to be packaged are always kept at a constant interval, and the bag making process is performed well. It is intended to provide an extremely innovative packaging device.

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

The transport of the package 3 is blocked by the positioning shutter plate 15 (or is in a closed state that can be blocked), and the package 3 is transported by retracting the positioning shutter body 15 upward. Conveyed together.

The positioning shutter body 15 moves toward the transport side with the hanging shutter closed, and pushes the package 3 back toward the transport side by this movement, and always positions the package 3 at a predetermined position. Can be set.

That is, for example, when the shutter body 15 is placed at the loading position by hand, after the shutter body 15 is positioned and placed using the shutter body 15 as a guide, the shutter body 15 once moves slightly toward the transport side,
As a result, the packaged object 3 is slightly pushed back, and is always positioned and set at a predetermined start position in a state where the packaged object 3 surely hits the shutter body 15. At this position, the shutter body 15 retreats (opens) upward, and the conveyance is started (restarted).

Also, in the automatic supply by the supply device 16, the shutter body 15 may be closed, but even if the packaged object 3 is open and slightly conveyed more than the start position (positioning position), the shutter body 15 may be closed. When the body 15 is closed and slightly returns to the transport side as described above, the packaged object 3 is pushed back, and is always positioned and set at a predetermined position.

Therefore, the package 3 always loaded can be positioned and set at a fixed position by the return position of the shutter body 15.
Since the positioning is performed by pushing back slightly at 15, the packaged object 3 always comes into contact with the positioning shutter body 15, and the positioning shutter body 15 and the packaged article 3 do not remain separated from each other. Biting or the like hardly occurs in the processing or cutting processing, and the positioning accuracy is dramatically improved.
