The product is sequentially extended from the front end portion of the product conveyance path by the number of product filling rows, and a product accumulation path for the number of filling rows is provided orthogonally to the inside of the front end portion of each product conveyance path, On the opposite side of each product conveyance path across each product conveyance path, the number of products in the filled row supplied to the tip of each product conveyance path is supplied to the respective product accumulation path. A batch supply section is provided, and a packaging material conveyance path is provided orthogonal to the leading end of the respective product stacking path, and from the leading end of the respective product stacking path to above the packaging material transport path In the above In the packaging material supplied to the transport path after adsorbing to the one-stage product supplied to the front end of the collection path of each product, transferring it above the transport path of the packaging material, and releasing the suction A product filling section for filling each is provided (claim 1).

  In the present invention, products are transported in parallel by a plurality of product transport paths, and a number of filled rows of products are collectively supplied from the respective product transport paths to a plurality of product stacking paths. Note that the number of products in the number of filling rows (minutes) refers to the number of products in a column or row that are filled in a row in the packaging material.

  The product conveyance path is not limited to two rows, and may be three or more rows. In that case, the product accumulation path is provided corresponding to the number of rows of the product conveyance paths. In the present invention, in each of the product transport paths, the front end portion of the outer product transport path is extended by the number of filled rows of the products from the front end portion of the product transport path positioned inside thereof.

  In other words, when the product conveyance path is provided in three rows in parallel, the front end portion of the inner intermediate product conveyance path is the same as the number of filled rows of the products, rather than the front end portion of the outermost product conveyance path. Further, the front end portion of the innermost product conveyance path is configured to be shorter than the front end portion of the intermediate product conveyance path by the number of filled rows of the products.

  When the product conveyance paths are provided in three rows in parallel, the products can be packaged in three layers in the packaging material. However, it is also possible to stack products in packaging materials using the same device. That is, a product conveyance path and a product accumulation path for two rows may be used.

  According to the present invention, unlike Patent Document 1, it is not necessary to distribute the products conveyed in one row from the manufacturing process on the wide conveyor and accumulate them in an appropriate number and an appropriate number. Therefore, automatic stacking packaging can be speeded up, and the apparatus is further simplified.

  One embodiment of the present invention is characterized in that a product alternating inversion device is provided in the middle of each product stacking path (claim 2). This product alternating inversion device is already known in Japanese Patent Application Laid-Open No. 2001-2023. By providing the product alternating inversion device in this way, the product accumulation space can be reduced, and therefore packaging materials can be saved, Furthermore, the space efficiency during storage and transportation is improved, and an economical effect can be obtained. In addition, in the packaging form that does not require the product alternating inversion device, the product alternating inversion device may be retracted upward.

  One embodiment of the present invention is characterized in that a product belt under the respective product alternating inversion devices is a non-slip conveyor belt (claim 3). The slippery conveyor belt in one embodiment of the present invention means to negate a slippery conveyor belt, and may be a general commodity transport conveyor belt. According to this embodiment, the products are alternately inverted upside down very smoothly.

  One embodiment of the present invention is characterized in that the front end portion of each product stacking path is a conveyor belt capable of independently driving and controlling the mounting width of the product in the number of packed rows. 4). According to this embodiment, it is possible to accurately perform the adsorption of the products corresponding to the number of packed rows supplied to the leading ends of the respective product accumulation paths in a state where the transfer of the products is temporarily stopped. .

  One embodiment of the present invention is characterized in that the packaging material is a corrugated cardboard sheet in the middle of the forming process (claim 5). According to this embodiment, automatic automatic supply and automatic stacking of goods to the cardboard case can be performed in synchronization with the molding process of the cardboard case.

  That is, it is difficult to automatically supply and automatically stack products in the corrugated cardboard case because the opening space is limited.

  Therefore, in addition to the lid flaps, the side flaps, and further, the products accumulated on the bottom flap of the corrugated cardboard sheet in the middle of the molding with the open end flaps, etc. are automatically supplied and stacked, and thereafter A packaging device for forming into a cardboard case in the conveyance process is suitable (for example, see Japanese Patent Publication No. 54-43955).

  One embodiment of the present invention is characterized in that the conveyance path of the packaging material is intermittently driven (Claim 6). According to this embodiment, it is possible to easily synchronize the transport of the packaging material and the filling timing of the product with respect to the packaging material.

  The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a schematic plan view of an automatic stacking packaging apparatus according to the present invention, FIG. 2 is a side view of the product conveyance path portion of FIG. 1, and FIG. 3 is a partially omitted arrow view taken along line XX of FIG. 4 is a view taken along the line Y-Y in FIG. 1, FIG. 5 is a view taken along the line ZZ in FIG. 1, FIG. 6 is a perspective view of the product inversion device, and FIG.
