It is a figure which shows the effect | action of the assembly apparatus of a cool box.

  Hereinafter, an apparatus for assembling a cool box according to the present invention will be described with reference to the illustrated embodiments. 1 and 2 show a cool box assembled by an assembling apparatus according to an embodiment of the present invention. FIG. 1 shows the cool box in a folded state, where reference numeral (a) is a view of the cool box viewed from above, symbol (b) is a view of the cool box viewed from the front, that is, from the opening side, and symbol (c) is cool. It is the figure which looked at the box from the side. FIG. 2 shows the cool box in an assembled state, wherein reference numeral (a) is a view of the cool box viewed from an opening, and reference numeral (b) is a view of the cool box viewed from the side.

  The cool box has first and second side plates 11 and 12, a pair of rotating side plates 13, a bottom plate 14, and a lid 15. In the folded state, the lid 15 is located at the top, and the second side plate 12 is located at the bottom. The first side plate 11 is below the lid 15, and a pair of rotating side plates 13 and a bottom plate 14 are sandwiched between the first side plate 11 and the second side plate 12. The bottom plate 14 is located immediately below the first side plate 11, and the pair of rotating side plates 13 are between the bottom plate 14 and the second side plate 12. That is, the cool box in the folded state is folded such that the bottom plate 14 and the rotating side plate 13 overlap with the first side plate 11, and the second side plate 12 is folded so as to overlap with the rotating side plate 13.

  The first and second side plates 11, 12 are provided in parallel, and can be relatively displaced in the enlargement / reduction direction. In the first side plate 11, a thin plate 17 extending along the first edge 16 is fixed to a pair of opposing first edges 16, and a rotating side plate 13 is pivotally attached to each thin plate 17. That is, the rotation side plate 13 is rotatably connected to the vicinity of the pair of first edge portions 16 facing each other in the first side plate 11.

  The bottom plate 14 is rotatably connected to the second edge 18 located between the pair of first edges 16 in the first side plate 11. As understood from FIG. 1C, the thickness of the bottom plate 14 is smaller than the difference D between the width of the thin plate 17 and the thickness of the first side plate 11. Therefore, the bottom plate 14 is inclined in the folded state, and a gap G is formed between the tip of the bottom plate 14 and the lower surface of the first side plate 11 on the opening 23 side. On the other hand, the lid 15 is rotatably connected to the first side plate 11 near the third edge 19 located on the opposite side to the second edge 18.

  The folded state of the cool box is maintained by the belt-shaped hook-and-loop fastener (connecting member) 20. The hook-and-loop fastener 20 is provided on the third edge 19 side, one end is fixed to the outer surface of the first side plate 11, and the other end is detachably adhered to the outer surface of the second side plate 12. That is, the folded state is maintained by fixing both ends of the hook-and-loop fastener 20 to the outer surfaces of the first and second side plates 11 and 12. Note that a handle 21 is attached to the outer surface of the second side plate 12.

  In the operation of assembling the cool box, first, the end of the hook-and-loop fastener 20 is separated from the second side plate 12. As a result, the second side plate 12 descends by its own weight relative to the first side plate 11, and the pair of rotating side plates 13 also rotate downward by their own weight (broken line B1 in FIG. 2A). At this time, if the turning side plate 13 is perpendicular to the first side plate 11, the bottom plate 14 also turns downward by its own weight (broken line B2 in FIG. 2B), but usually, the turning side plate 13 is in a vertical state. And stop at an inclined half-open state. Therefore, the bottom plate 14 cannot rotate sufficiently downward, and is locked to the rotation side plate 13 to be in an inclined state. In the present embodiment, the opening means (not shown) expands the rotating side plate 13 and presses the bottom plate 14 so that the bottom plate 14 and the rotating side plate 13 are perpendicular to the first side plate 11 as described later. Determined.

  In the cool box assembled in this manner, the pair of rotating side plates 13 and the bottom plate 14 are set to be perpendicular to the first and second side plates 11 and 12, and have a box shape. The outer surfaces of the cool box, that is, the outer surfaces of the first and second side plates 11 and 12, the pair of rotating side plates 13 and the bottom plate 14 are covered with a protective sheet 22. The protection sheet 22 is a relatively flexible heat insulating material sheet. In the folded state, the protection sheet 22 is folded inward, and a part thereof is sandwiched between the second side plate 12 and the rotation side plate 13 (see FIG. 1B).

The assembling apparatus of the cool box 10 will be described with reference to FIGS.
The frame 30 is provided with various mechanisms for changing the cool box 10 from the folded state to the assembled state. On the side of the frame 30, there is provided a support base 31 for supporting the cold storage boxes 10 stacked in a plurality of stages (five in FIG. 3) in a folded state, and between the frame 30 and the support base 31.

The cool boxes are stacked on the support table 31 such that the openings 23 face the gripping claws 37 and 38. First, the first air cylinder 35 is driven, and the gripping claws 37 and 38 and the connection release mechanism 39 move forward and approach the cold storage box 10 at the uppermost stage (reference numeral (a)). At this time, the upper gripping claw 37 is located on the lid 15 of the cool box 10, and the lower gripping claw 38 is located in the lower gap G of the first side plate 11. On the other hand, the connection release mechanism 39 is inclined downward, and the release member 47 (FIG. 5) is at a position away from the cool box 10.

  Next, as shown by the reference numeral (b), the upper gripping claw 37 is rotated downward, and the first side plate 11 and the lid 15 are gripped by the upper gripping claw 37 and the upper gripping claw 38. Immediately after this, the gripping claws 37, 38 are displaced upward, and the gripping claws 37, 38 and the connection release mechanism 39 are retracted. As a result, the portion on the opening 23 side of the uppermost cold storage box 10 protrudes from the lower cold storage box.

  Then, as shown by reference numeral (c), the connection release mechanism 39 rotates upward, the motor 45 is driven, and the release member 47 (FIG. 5) swings. The release member 47 engages with the hook-and-loop fastener 20, peels off the end of the hook-and-loop fastener 20 from the second side plate 12, and then returns to a position where it does not interfere with the cool box 10.

  Thereafter, as shown by reference numeral (d), the gripping claws 37 and 38 and the connection release mechanism 39 are retracted, and the connection release mechanism 39 is rotated downward. By the retreat of the gripping claws 37, 38, the cool box 10 is separated from the other cool boxes, and the second side plate 12 is released from the cool box below and descends by its own weight. Thereafter, the opening member 51 advances and approaches the opening 23 of the cool box 10.

  Next, as shown in symbols (e) and (f), the second side plate 12 descends relatively to the first side plate 11 while the gripping claws 37 and 38 descend. Along with this, the pair of rotating side plates 13 also rotate downward by their own weight, and the bottom plate 14 gradually rotates downward while engaging with the rotating side plate 13. On the other hand, the opening member 51 advances and enters the cool box 10 from the opening 23 in the half-open state, and the engagement surface 53 spreads the rotating side plate 13 to both sides. Then, the pressing is performed so that the contact surface 52 comes into contact with the bottom plate 14 and is perpendicular to the first and second side plates 11 and 12 (symbol (g)).

  As described above, in the present embodiment, the holding members 37 and 38 hold the first side plate 11 and the lid 15, and the opening member 51 enters from the opening 23 of the cold insulation box 10 where the second side plate 12 is lowered and spread. Then, the bottom plate 14 and the rotation side plate 13 are opened from the half-open state to the fully-open state by contacting the bottom plate 14. Thereby, the first and second side plates 11 and 12, the pair of rotating side plates 13 and the bottom plate 14 are formed into a predetermined box shape, and the cool box is mounted on the mounting table 32 with the opening 23 directed sideways. Is placed.

  Therefore, according to the present embodiment, the cold storage box in the folded state can be automatically assembled into a box shape without manual intervention.

  In the above embodiment, the uppermost cold box is taken out by the gripping claws 37, 38. However, the present invention is not limited to this. For example, the lower cold box may be taken out. Applicable. In this case, it is necessary to displace another cold storage box stacked above the lowest cold storage box in the removal operation of the lowest cold storage box. May be held.

Further, instead of pressing the bottom plate 14, the bottom plate 14 may be released by grasping and swinging.
Further, the disconnection means may be configured to move linearly, or the cool box may be moved while fixing the disconnection means.

  Further, in the above embodiment, the hook-and-loop fastener 20 for maintaining the folded state of the cool box has a band shape, one end of which is fixed to the outer surface of the first side plate 11, and the other end is detachably adhered to the outer surface of the second side plate 12. However, it may be provided on the outer surface of the protection sheet 22 instead. In this case, the protection sheet 22 is formed so as to be bent inward along a straight line (bent curve) parallel to the side plates 11 and 12 so as to be bent inward at an intermediate position between the first side plate 11 and the second side plate 12. The hook-and-loop fastener is provided adjacent to the folding line. That is, in the folded state, the hook-and-loop fastener adheres and the bent state of the protection sheet 22 is maintained, and the hook-and-loop fasteners are separated from each other by forcibly separating the first side plate 11 and the second side plate 12. Therefore, the connection release mechanism may be configured to insert a plate-like member between the first side plate 11 and the second side plate 12, or may be configured to press the second side plate 12 to separate it from the first side plate 11.
