Description

  In the present invention, the contents of detergents, cosmetics, seasonings, pharmaceuticals, etc. are to be packaged, and this is formed into a packaging bag (bag-like container) or synthetic resin formed by overlaying synthetic resin films. The present invention relates to a filling apparatus suitable for filling a packaging bag formed by laminating films of aluminum and foil such as aluminum.

  In recent years, packaging bags have been used as containers for filling and packaging contents for refilling from the viewpoint of effective use of resources and reduction of garbage.

  The packaging bag is filled with the contents, and the so-called heat sealing method is adopted in which the filling port is heat-sealed and sealed, and is provided at the filling port when the filled package is poured out. The container is opened by tearing off the picked portion.

  Conventionally, when filling this type of bag with the contents, the contents stored in advance in the tank are continuously transferred by a pump connected thereto and filled through a filling nozzle provided at the end of the conveying path. Yes.

  By the way, when the contents are transferred by the pump, it is inevitable that air is mixed in the contents, and if this is present in the transfer path, the contents flow along the transfer path together with the contents to be transferred. As a result of filling the packaging bag with air mixed, it is often found that the quantity is insufficient, and in this case, there is a problem that the product cannot be shipped as a product.

  For this reason, usually, when the filling facility is started or periodically, the contents are sent into the transport path, and the air is pushed out together with the contents from the filling nozzle to extract the air.

  However, this air evacuation work inevitably causes leakage of the packaged goods that leads to product loss, and it also takes time and effort, which also has an impact on productivity. It was sought after.

  As a prior art regarding this point, Patent Document 1 discloses, as a filling device for an article to be packaged, a tank that accommodates the article to be packaged and an automatic packaging machine that are connected by a supply path. There is a packing filling device for automatic packaging machines in which a filling pump is provided on each side of the machine, and the pump on the tank side is a relatively large capacity pump, while the pump on the automatic packaging machine side is a relatively small capacity. It is disclosed.

It is the figure which showed other embodiment of the filling apparatus of the to-be-packaged goods according to this invention in the cross section of the principal part.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a diagram schematically showing an embodiment of an apparatus for filling a package according to the present invention.

  Reference numeral 1 in FIG. 1 is a tank (hopper) for storing the article to be packaged, 2 is a pump for transferring the article to be packaged in the tank 1 (a pump that can intermittently feed the article to be packaged, etc.) 3 is a filling nozzle for filling a bag-like container with an article to be packaged, 4 is a path that connects the tank 1 and the pump 2, and 5 is a conveyance that connects the pump 2 and the filling nozzle 3. It is a route. The conveyance path 5 is composed of a plurality of pipes connected through a flange.

  Reference numeral 6 denotes a T-shaped tube (cheese) disposed in the middle of the transport path 5. The cheese 6 is composed of a vertical tube 6a and a horizontal tube 6b that is connected at a substantially central portion in the longitudinal direction of the vertical tube 6a.

  As shown in FIG. 2, the vertical pipe 6 a of the cheese 6 forms a vertical passage through which an article to be packaged flows from below to above (from below to above in the figure) ( An upward flow is formed), and a trapping area P for trapping air mixed in the package is provided at the upper part thereof.

  Similarly, as shown in FIG. 2, the cross-section 6b of cheese 6 has an entrance-side opening M (opened upward in this example) that opens in any direction from sideways to upward. And a tube body 7 for changing the flow direction of the packaged object in the vertical tube 6a. The tube body 7 is used to change the flow direction of the packaged object. A deflection path for changing is formed.

  Here, in this example, the tubular body 7 is shown as a separate body from the lateral tube 6b, but may be formed integrally with the lateral tube 6b.

  8 is a short pipe connected to the upper part of the vertical pipe 6a of the cheese 6, 9 is an air release valve (a ball valve or the like is applied) connected to the short pipe 8, and 10 is a bag for filling an object to be packaged. Shaped container (packaging bag).

  As the bag-like container 10, a long film-like sheet is overlapped to form a vertical seal portion at both width ends, a horizontal seal portion is formed at the lower end, and each is bonded, and a filling nozzle is formed from the upper open end. After being inserted and filled with an article to be packaged, a lateral seal portion is formed at the upper end portion and sealed by heat sealing.

  Although not shown in the drawing, the filling device described above is provided with a stacking unit for stacking films and a vertical seal at both width ends of the stacked films in order to form a bag-like container 10 (bag making). A vertical seal forming part to be formed, a horizontal seal forming part for forming a horizontal seal on the top and bottom of one container, and a cutting part for separating the continuous containers 10 one by one or for each plurality of bags are provided. In addition, a control device for controlling the pump 2 and the filling nozzle 3 is provided so that a predetermined amount of an object to be packaged can be filled in the container 10, so that the object can be continuously filled. ing.

  Here, the overlapping part is a part where one long laminated film that is fed out from a single film roll and folded in two at the center in the width direction is overlapped. The vertical seal forming part that follows the part is a part that heats and seals both ends of the laminated film in the width direction continuously along the longitudinal direction to form the laminated film into a cylindrical shape.

  Then, in the horizontal seal forming part, the laminated film filled with the package is heat-sealed over the entire width by the horizontal seal roll while pulling left and right at both ends in the width direction to form the horizontal seal part. A bag filled and sealed with a package is continuously formed, and is cut at a horizontal seal portion or a vertical seal portion at a cutting portion following the horizontal seal formation portion, and divided into one bag or a plurality of bags. The

  In such a filling apparatus, even if air is mixed in the article to be packaged that passes through the conveyance path 5, the air is collected in the collection area P provided at the upper portion of the vertical passage as shown in FIG. Further, since the articles to be packaged in the vertical path P are directed to the filling nozzle 3 through the entrance opening M opened upward, air to the articles to be packaged through the deflection path Are not mixed, and the container 10 is filled with a predetermined amount of an object to be packaged.

  In particular, when submerged seal filling is performed in which the container 10 is filled with an object to be packaged and then heat-sealing is performed while the object to be packed filled with the horizontal seal roll is squeezed, the amount of air present in the container 10 is reduced. Since it is extremely reduced, the effect of preventing oxidation (degeneration), the effect of suppressing the generation of soot, and the like are further enhanced, and the packaging object can be stored for a long time.

  In applying the filling device by applying the filling device according to the present invention, first, the pump 2 is started with the air release valve 9 opened. Thereby, since the pressure in the supply path 5 is released, the packaged material does not flow to the filling nozzle 3 side even when the pump 2 is activated, and the longitudinal tube 6a of the cheese 6 does not flow. The liquid level increases at.

  When the air release valve 9 is closed when this level is higher than the air release valve 9, the pressure in the feed path 5 increases, and the filling object can be filled by the filling nozzle 3. .

  In order to remove the air collected in the collection area P, the air level valve 9 may be opened by opening the atmosphere release valve 9 and starting the pump 2 when the apparatus is stopped. Is placed above the air release valve 9 to remove all of the collected air.

  Regarding the air removal operation, since the collection area P is provided separately, the number of operations can be reduced as compared with the conventional method, and the discharge amount (leakage amount) of the packaged goods that leads to product loss is extremely high. There are advantages that can be reduced.

  FIG. 3 shows a flow speed reduction mechanism (for example, a reducer whose pipe diameter is different between the inlet side and the outlet side) 11 on the inlet side of the cheese 6, and the lower end of the short pipe 8 has a larger diameter and an upper end. It is the figure which showed other embodiment of the filling apparatus according to this invention which applied the pipe of the different diameter type which made small diameter.

  In the filling device having such a configuration, since the circulation speed of the article to be packaged in the vertical pipe 6a can be reduced by the circulation speed reduction mechanism 11, it is avoided that air is caught in the article to be packaged toward the deflection path. Stable quantitative filling of packages is possible.

  For example, as shown in FIG. 4, the tubular body 7 forming the deflection path can be inclined so that its exit end N is lower than the entrance opening M. The prevention effect can be further enhanced.

  Further, FIG. 5 shows still another embodiment of the filling device for a package according to the present invention.

  In this example, a vertical passage is constituted by an inner tube 12 having an outflow opening h for an object to be packaged at an upper end and an outer tube 13 having a concentric double arrangement surrounding the inner tube 12. While the lower end is connected to the transport path 5, the outer tube 13 is provided with a horizontal tube 13 a that forms a deflection passage in the peripheral wall below the outflow opening h.

  Even in the filling device having such a configuration, the air mixed in the article to be packaged is collected in the collection area P formed in the upper part thereof.

  Further, the article to be packaged is decelerated when it comes out of the outflow opening h, and reaches the entrance side opening M of the horizontal pipe 13a through the narrow annular passage 14 formed between the inner pipe 12 and the outer pipe 13. Therefore, there is no concern that air is caught in the package, and this also enables the quantitative filling of the package.

  In the filling device having the configuration as shown in FIG. 5, the effect of preventing air entrainment can be enhanced by making the exit end of the horizontal tube 13 a forming the deflection passage lower than the entrance opening M.

  The entrance side openings M and h of the deflection passage are shown as examples of those that are opened upward and those that are opened sideways from the viewpoint of reliably preventing the intrusion of air. h can be appropriately set in an arbitrary direction from the horizontal direction to the upward direction, and this point is not particularly limited.

  According to the present invention, air that is unavoidable to be mixed in the package can be effectively removed in the feeding process, so that the quantitative filling that can fill the package with a specified amount is possible. It becomes possible.

  Further, according to the present invention, it is possible to reduce the number of operations for removing air, and it is possible to minimize leakage of the packaged goods that leads to product loss, so that filling with a high yield can be performed.
