[0013] First, with reference to FIGS. 1 to 3, an embodiment of the packaging pack molding apparatus of the present invention will be described. The molding and packaging apparatus is composed of a tray molding apparatus 10 shown in FIG. 1 and a mount board attaching apparatus 50 shown in FIG. 3. The tray molding apparatus 10 will be described as Example 1. FIG. 1 shows the tray molding apparatus 10 according to Example 1. FIG. 1(A) shows the configuration of the tray molding apparatus 10, and FIGS. 1(B) to 1(D) show the cross-sectional states in the main operations viewed in the arrow direction along the line #1-#1 in the same figure.

[0014] In these figures, the tray molding apparatus 10 includes a lower jig 100 and a molding upper jig 200. The lower jig 100 has a setting table 120 provided on the upper surface of a box-shaped housing 110, and a receiving base 130 is provided below it. Inside the housing 110, support columns 112 are provided at the four corners, and these support columns 112 penetrate the receiving base 130. Each support column 112 is provided with a support spring 114, and by these, the receiving base 130 is supported so as to be vertically movable.

[0015] The setting table 120 is provided with a recess 122 for molding a tray (product storage part) of the packaging pack substantially at the center. At the four corners of the recess 122, positioning pins 124 for positioning with the molding upper jig 200 and a mounting upper jig 300 described later are respectively provided. Also, positioning pins 126 for positioning with the molding upper jig 200 to the mounting upper jig 300 are provided at positions away from the recess 122.

[0016] The receiving base 130 provided below the setting table 120 has a larger area than the recess 122, and lifting pins 132 are provided to mold the standing part of the tray side paper 20 and to enable good positioning without the mount board 60 coming into contact with the pasting part 30 of the tray side paper 20 described later. In the illustrated example, they are respectively provided at positions corresponding to the four corners of the recess 122. As shown in FIG. 1(B), these lifting pins 132 penetrate the setting table 120 and protrude, and move up and down together with the receiving base 130.

[0017] Next, the molding jig 200 is provided with a convex portion 202 that enters the concave portion 122 of the set base 120 described above to perform molding, and positioning holes 204 and 206 through which the positioning pins 124 and 126 of the set base 120 penetrate are provided respectively.

[0018] The molding paper of this embodiment is composed of a tray-side paper that forms the product storage portion of the packaging pack and a lid-side paper that covers the product storage portion. Among these, as shown in FIG. 1(A), the tray-side paper 20 is provided with standing portions 24 and 26 on each side of the rectangular bottom portion 22, and standing portions 28 are provided on the side surfaces of the standing portions 26 on the short side. Further, adhesive portions 30 are provided on each side of the standing portions 24 and 26. The standing portions 24 and 26 form the side surfaces of the product storage portion, and the standing portions 28 are provided to ensure the strength of the corners. The adhesive portion 30 is for attaching the lid-side paper. Folding lines for folding are appropriately provided at the boundaries of these portions.

[0019] Next, referring also to FIG. 2, the operation of tray molding according to this embodiment will be described. First, the tray-side paper 20 in FIG. 2(A) is placed on the concave portion 122 in alignment with the positioning pin 124 of the lower jig 100. In this state, as shown in FIG. 1(B), the standing portion 28 is located on the lifting pin 132.

[0020] Next, the molding upper jig 200 is positioned with respect to the lower jig 100 such that the positioning pins 124 and 126 enter the positioning holes 204 and 206 respectively. Then, when the molding upper jig 200 is pushed into the lower jig 100, first, the standing portions 28 at the four corners stand up by the lifting pins 132 as shown in FIG. 2(B). Then, when the molding upper jig 200 is pushed in further, the convex portion 202 of the molding upper jig 200 enters the concave portion 122 of the lower jig 100, and the lifting pins 132 are pushed by the molding upper jig 200, and the receiving base 130 descends toward the housing 110 side against the support spring 114.

[0021] Furthermore, when the forming jig 200 is pushed in further, the standing portions 24 and 26 on the four sides of the tray-side paper 20 stand up along the concave portions 122. At this time, the standing portions 28 at both ends of the short-side standing portion 26 enter inside the long-side standing portion 24 (see Fig. 2(C)). Furthermore, when the forming jig 200 is pushed in further, the pasted portion 30 is bent outward along the side surface of the convex portion 202 of the forming jig 200 as shown in Fig. 1(C). After that, when the forming jig 200 is removed, the support spring 114 extends and the receiving base 130 rises, resulting in the state shown in Fig. 1(D). Through the above operations, the forming of the tray-side paper 20 is performed (see Fig. 2(D)).

Embodiment

[0022] Next, with reference to Fig. 3, an embodiment 2 of the mount board attaching device 50 for attaching a mount board to the above-described tray will be described. Fig. (A) of the same figure shows the configuration of the mount board attaching device 50, and Figs. (B) to (D) of the same figure show the cross-sectional states in the main operations when viewed in the arrow direction along the #3 - #3 line of the same figure. In these figures, the mount board attaching device 50 includes the lower jig 100 shown in Fig. 1 and the attaching upper jig 300.

[0023] The attaching upper jig 300 is provided with a frame-shaped convex portion 302 with a heater for thermocompression bonding a mount board 60 serving as a lid around the concave portion 122 of the above-described set base 120, and positioning holes 304 and 306 through which the positioning pins 124 and 126 of the set base 120 penetrate are respectively provided. The mount board 60 is also provided with a positioning hole 62 through which the positioning pin 126 penetrates. In addition, on the long-side of the attaching upper jig 300, four positioning legs 308 are provided so as to oppose each other. These positioning legs 308 are for positioning the attaching upper jig 300 with respect to the lower jig 100 when attaching the mount board.

[0024] Next, the operation of this embodiment will be described. The tray 40 formed by molding the tray-side paper 20 according to the above-described Embodiment 1 is within the concave portion 122 of the lower jig 100. In this state, while the product 52 is put into the tray 40, the base paper 60 is placed on the tray 40 so as to be inside the positioning pins 124. At this time, the positioning holes 62 of the base paper 60 are longitudinally positioned so that the positioning pins 126 of the setting base 120 penetrate therethrough. In this state, the base paper 60 is placed on the elevating pins 132 of the jig 100 at appropriate intervals (see Fig. 3(B)). By taking intervals with the elevating pins 132, the base paper 60 can be properly positioned without directly contacting the pasting portion 30 of the tray 40.

[0025] Next, with respect to the lower jig 100, the mounting upper jig 300 is placed on the lower jig 100 using the positioning holes 304, 306 and the positioning legs 308, and its convex portion 302 is pressed so as to heat and crimp the pasting portion 30 of the tray 40. Then, the receiving base 130 descends toward the housing 110 against the support spring 114. The elevating pins 132 also descend, and the base paper 60 is heat-crimped to the tray 40 on four sides (see Fig. 3(C)).

[0026] After that, when the mounting upper jig 300 is removed, the product 52 is stored in the tray 40, and the packaging pack 70 covered with the base paper 60 is completed (see Fig. 3(D)). The positioning holes 62 of the base paper 60 can be used when the packaged pack 70 is suspended and displayed on a product shelf (not shown).

[0027] As described above, according to this embodiment, a. Since all of the tray 40 and the base paper 60 of the packaged pack 70 are made of paper, plastic is not used, and the environmental load is affected. b. Since the common lower jig 100 is used by the tray molding device 10 and the base paper mounting device 50, the work can be efficiently performed.

Embodiment

[0028] Next, referring to FIGS. 4 and 5, Example 3 of the present invention will be described. In this example, a plurality of the lower jigs 100 described above are arranged on a table in a circular shape, and the molding upper jig 200 and the mounting upper jig 300 are combined therewith, and the table is rotated so that packaging work can be efficiently performed. FIG. 4 shows a molding and packaging apparatus 500 of this example. On a work table 502, apparatuses for each process of a tray paper input unit 510, a tray molding unit 512, a product input unit 514, a mount paper input unit 516, a mount paper crimping unit 518, and a packaged pack take-out unit 520 are arranged side by side. The operations of these apparatuses are as shown in Examples 1 and 2 described above. FIGS. 5(A) to (F) briefly show the operations of the respective apparatuses 510 to 520.

[0029] <Other Embodiments> The present invention has numerous embodiments and can be variously modified based on the above disclosure. For example, the following are also included. (1) The shapes and dimensions shown in the above examples are merely examples, and the design can be changed so as to achieve the same effects. There may be a plurality of trays 40 in one packaging pack. (2) In the above example, the standing portions 28 are provided at the four corners of the tray 40 to improve the strength. However, if the standing portions 28 are unnecessary, they may be omitted. (3) In the above example, the mount paper 60 is adhered at the gluing portions 30 on the four sides of the tray 40. However, the area for gluing can be appropriately set. For example, in one gluing portion 30, spot gluing may be performed at three portions of both ends and the center. (4) The content and handling instructions of the product may be displayed on the tray-side paper 20 or the mount paper 60. (5) Windows may be provided in the tray 40 or the mount paper 60 so that the contents can be seen.

Industrial Applicability

[0030] According to the present invention, since paper is used for the tray and the mount board instead of plastic, adverse effects on the environment can be reduced. Also, since a common lower jig is used for the tray forming device and the mount board attaching device, the working efficiency can be improved by performing tray forming and mount board crimping simultaneously, which is suitable for packaging the formed products of the tray.
