  FIG. 1 is a cross-sectional view showing a partial configuration of a general packaging apparatus. The packaging apparatus includes a transport mechanism 60 that transports the box material 10 in a predetermined transport direction, and an article on the box material 10 that is transported by the transport mechanism 60 by pressing the article 20 from the first side of the transport mechanism 60. 20, a rail 62 disposed on the first side of the transport mechanism 60, a rail 64 disposed on the second side of the transport mechanism 60, and the inner surface of the box 10 by the filling mechanism 70. And a guide mechanism 80 arranged on the second side of the conveyance mechanism 60 and for guiding the box material 10.

  The guide mechanism 80 includes two guide bars. Due to the presence of the guide mechanism 80, the box material 10 is accompanied by the ruled line (bending line) of the box material 10 along with the conveyance by the conveyance mechanism 60, and the original folding direction (the direction in which the box material 10 is folded when being box-shaped). It is bent in the opposite direction. At this time, the ruled lines of the box material 10 are bent so that the rails 64 coincide with the ruled lines.

  In the packaging device having the configuration as shown in FIG. 1, when the type (specification or characteristic) of the box material 10 is changed by changing the manufacturer of the box material 10 or the like, the strength and ruled line of the box material 10 are changed. The strength of the box member 10 may be lowered due to a change in strength or a change in ruled line structure. Moreover, when the packaging apparatus which has such a structure is used over a long period of time, the rail 64 will be worn out and it will become difficult to position the box material 10 correctly. Therefore, a molding defect of the box material 10 may occur.

  The present invention has been made on the basis of the above problem recognition. For example, the necessary positioning accuracy is ensured regardless of the type of the box material and / or the deterioration of the positioning accuracy is prevented. For the purpose.

  A packaging device according to the present invention is configured to wrap an article with a box material while forming a plate-like box material into a box shape, and a transport mechanism that transports the box material in a transport direction; A filling mechanism for filling the article onto the inner surface of the box material being conveyed by the conveyance mechanism by pushing the article from one side; a region where the article is filled on the inner surface of the box material by the filling mechanism; and And a guide member that is disposed on the second side of the transport mechanism and guides the box material. The guide member has a guide surface with which an end portion of the outer flap of the box material abuts when the filling mechanism fills an inner surface of the box material, and the end portion of the outer flap is the guide portion. The box material is positioned by being brought into contact with the surface.

  According to a preferred embodiment of the present invention, the packaging device may further include a position adjustment mechanism that adjusts the position of the guide member.

  According to the present invention, for example, it is possible to ensure necessary positioning accuracy regardless of the type of box material and / or to prevent a decrease in positioning accuracy.

  In the following, an embodiment which is considered to be the best for carrying out the present invention will be described.

  FIG. 2 is a diagram schematically showing the configuration of the packaging device according to the preferred embodiment of the present invention. The packaging device 100 according to a preferred embodiment of the present invention wraps an article 20 such as a beer can or a beverage can while bending a plate-like box material (carton material) 10 into a box shape. In the example shown in FIG. 2, the article 20 is a can product such as a beer can or a beverage can. For example, an assembly of 4 × 6 pieces can be packaged by the box material 10. In the so-called multi-pack product, typically, an assembly of four multi-packs each packaged in units of 2 × 3 can be packaged by the box material 10.

  In the packaging of the article 20, the box material 10 is taken out one by one from the box material group 10 </ b> S composed of a plurality of box materials 10 stacked in a plate state, and, for example, in the A region, two sides of the trunk portion (main body portion) Is folded and placed on the conveyance path of the conveyance mechanism (conveyor) 60. Thereafter, the box material 10 is processed while being transported in the transport direction by the transport mechanism 60.

  Next, in the area B, the inner flap 1 on the guide member 90 side is bent by about 90 degrees, the article 20 is filled on the inner surface of the box material 10 by the filling mechanism 70, and then the inner flap 2 on the filling mechanism 70 side. Is also bent about 90 degrees.

  FIG. 3 is a schematic cross-sectional view of the packaging device in region B of FIG. The filling mechanism 70 pushes the article 20 from the first side (the −y direction side) of the transport mechanism 60 toward the transport path of the transport mechanism 60, so that the filling mechanism 70 is on the inner surface of the box material 10 being transported by the transport mechanism 60. The article 20 is filled. The guide member 90 is disposed in a region (B region) where the article 20 is filled on the inner surface of the box material 10 by the filling mechanism 70 and on the second side (+ y direction side) of the transport mechanism 60. To guide. When the filling mechanism 70 fills the article 20 on the inner surface of the box material 10, the guide member 90 is brought into contact with the end of the outer flap 2 of the box material 10 by the frictional force between the article 20 and the box material 10. The box material 10 is positioned by having a guide surface 90g and the end of the outer flap 2 abutting against the guide surface 90g.

  According to such a positioning mechanism, the problem that the positioning accuracy decreases with the wear of the rail 64 is solved. Here, the guide surface 90g of the guide member 90 can also be worn, but the guide surface 90g is a simple one that positions the box material 10 by contacting the end of the outer flap 2 of the box material 10 against the guide surface 90g. Positioning means. Therefore, when the guide surface 90g is worn, the guide member 90 may be simply moved by the amount of wear. For this purpose, the packaging device preferably includes a position adjustment mechanism 95 that adjusts the position of the guide member 90.

  The box material 10 that has passed through the B region is then provided with glue in place on the outer surface of the folded inner flap 1 in the C region. For example, the glue is sprayed from the glue jet nozzle 30 to a suitable place on the inner flap 1.

  Next, in the flap folded region 40r including the D region and the E region, the box material 10 is formed into a quadrangular cylindrical shape by bending the remaining one side of the body portion (main body portion) by about 90 degrees and The outer flap 2 is bent in the vertical direction.

  Next, the box material 10 in which the article is packaged is conveyed further downstream through the flap pressing area 50r. At this time, the outer flap 2 is securely glued to the inner flap 1 while the outer flap 2 is pressed against the inner flap 1 so that the box material 10 becomes a complete box.

It is sectional drawing which shows the partial structure of a general packaging apparatus. It is a figure which shows typically the structure of the packaging apparatus of suitable embodiment of this invention. It is typical sectional drawing of the packaging apparatus in the B area | region of FIG.
