  For this type of logistics reel, the product name, product number, specifications such as length and width, factory name, manufacturer name, and other detailed information of the long product to be wound are printed on the label or sticker and the flange. Often attached to the outer surface of. In particular, in the case of physical distribution reels used in electronic component mounting processes, the amount of information described on labels and stickers (hereinafter referred to as “printed matter”) is extremely large, and therefore, they are described. Therefore, the printed material becomes larger. In particular, in recent years, cases in which a plurality of printed materials are pasted or various information are written together with barcodes are increasing, and accordingly, the pasting area of the printed materials tends to be further increased.

  Under such circumstances, it is required to secure a wide flat surface on which the large printed matter can be attached to the flange of the logistics reel. However, if an attempt is made to form such a wide flat surface, the amount of resin required for forming the flange increases accordingly, resulting in an increase in cost and weight. Therefore, the present invention provides a distribution reel structure suitable for securing the necessary rigidity while saving the amount of resin required for forming the flange when forming a wide flat surface on which the printed matter is to be attached to the flange. It is to provide.

  The configuration for solving the above-described problems will be described using the reference numerals used in the drawings showing the embodiment. The physical distribution reel of the present invention includes a core (2) around which a long object is wound, and the core (2). A pair of disk-shaped flanges (3) and (3) provided at both ends of the flange (3), and an injection molded logistics reel (4) and other printed matter affixed to the outer surface of the flange (3) ( 1) or at least one of the pair of flanges (3), (3) is provided with a plurality of window openings (31), and the flanges (3) excluding the window openings (31) (3) ) In a distribution reel (1) made of injection molding in which a label (4) other printed matter is attached to a partial region of the outer surface, the outer surface of the attached region of the printed matter is formed flat, while the attached region of the printed matter The thickness of the flange (3) is approximately the same on the inner surface of Thinned-out part to reduce a thickness of (38), characterized in that it is formed over the majority of the attaching area.

  In order to attach a large printed matter to the flange (3) of the physical distribution reel (1), a flat surface having no irregularities corresponding to the size must be ensured. In the physical distribution reel (1) in which the flange (3) does not have a window opening (31), the entire surface of the flange (3) serves as a print application region. In many logistics reels (1), a plurality of window openings (31) are formed, and a plurality of spokes extending from the core (2) side toward the outer peripheral side are provided between them. Among these spokes, the outer surface of the spoke having a particularly large area is a sticking area for the printed matter.

  In other words, the “printed region” in the present invention means a substantially unitary region provided on the side surface of the flange (3), such as the outer surface of the spoke having the largest area to be found. However, the pasting area is not strictly defined, and slightly changes depending on the form of the window opening (31) formed in the flange (3) and the shape of the printed matter to be pasted.

  When reinforcing ribs (34) and (35) are formed on the outermost peripheral edge of the flange (3) and the peripheral edge of the window opening (31), the ribs (34) and (35) are formed. The inner area excluding “” is defined as the printed application area. And the rib and other unevenness | corrugation which becomes obstructive of printed matter sticking are not provided in the inside of this sticking area | region, but the outer surface is formed flat.

  Here, if the thickness of the entire flange (3) is increased in order to ensure the rigidity of the region where the rib is not formed, the amount of resin is greatly increased by the amount of the area that is found in the region, resulting in an increase in cost. It will be. Therefore, the present invention realizes a reduction in the amount of resin and a reduction in weight while ensuring the necessary rigidity by forming a meat stealing portion (38) on the back side of the majority of the pasting area of the printed matter. is there.

  If the meat stealing portion (38) is formed over at least the majority of the pasting region of the printed matter, the effect of reducing the amount of resin is increased by the amount of the area found in the region. The meat stealing portion (38) may be a group of regions, or may be divided into a plurality of appropriate regions (sections) having a radial shape or a concentric shape. The portion that remains thick has the effect of improving the rigidity of the flange (3) in cooperation with reinforcing ribs (34), (35), etc. formed on the outer surface of the flange (3). The arrangement of the thick part is preferably designed in consideration of the structural balance in consideration of the shape of the window opening (31) and the like.

  According to this configuration in which the meat stealing portion (38) is partially formed on the inner surface of the flange (3), the facing distance (minimum dimension of the inner method) between the flanges (3) and (3) is unchanged. Therefore, there is no hindrance to winding and feeding of a long object, and it is not necessary to change the dimensional standard related to winding.

  Further, as a secondary effect, by forming the meat stealing portion (38) on the inner surface of the flange (3), contact friction between the flange (3) and the long object is reduced at least at that location. Thereby, the pain of the long object by friction, generation | occurrence | production of fine abrasion waste, etc. can also be reduced.

  The physical distribution reel of the present invention configured as described above can ensure the rigidity of the flange while saving the amount of resin required for molding by forming a meat stealing portion on the back surface of the printed material pasting area on the flange. it can. Further, by reducing the basis weight (weight per product unit), it is possible to economically manufacture a physical distribution reel suitable for attaching a large printed matter, and the productivity is improved.
