  The present invention relates to a loading / unloading apparatus, and more particularly, to a loading / unloading apparatus capable of efficiently storing and loading / unloading articles wound in a roll shape.

  Raw materials such as industrial films such as polyester film and polyolefin film, and paper such as high-quality paper and processed paper are wound in a roll shape using a substantially cylindrical core material and stored in a warehouse. The raw material wound in such a roll shape is formed by, for example, applying and forming an adhesive or the like on one side of the film, sticking a release sheet, and then dividing into a plurality of wound bodies using a slitter or the like. Secondary processing such as is generally adopted. In addition, some of them are wound in a roll shape and stored in a warehouse in the same manner as the original fabric before being subjected to adhesive processing and subjected to secondary processing such as slitting.

  Therefore, the roll-shaped article in the original fabric state has a large roll width and winding diameter, and a very heavy weight. Therefore, when such articles are held in stock, it is usual to use a loading / unloading apparatus including a large rack apparatus composed of a three-dimensional frame structure provided in a factory.

  For example, Patent Document 1 discloses the entry / exit device. The loading / unloading device shown in the document includes a rack device that supports an article wound in a roll shape on the outer peripheral side of a core material, and a crane that loads and removes the article with respect to the rack device. Yes. The article is provided with a length having both ends of the core member extending from both ends in the width direction of the roll, and the rack device includes a pair of support members that respectively support the extensions. It has a configuration with.

  Next, the unloading operation by the loading / unloading apparatus 10 according to the present embodiment will be described.

  Here, for convenience of explanation, it is assumed that the loader 12 stands by with the position shown in FIG. 1 as the initial position, and the lifting body 32 of the loader 12 is at the lower limit. In addition, the entrance / exit lifter 14 is assumed to be at a height where the front receiving arm 77 and the rear receiving arm 78 can receive the article W from the loader 12.

  When the article W to be delivered is instructed via the control device, the control device specifies the address of the article W, and a drive signal corresponding to the address is given to the loader 12. Then, in the loader 12, the pinion P rotates through the motor M and rolls along the rack R, and the loader 12 moves along the guide rails 13 and 13 to the side position corresponding to the position of the article W. Will stop. At this time, the elevating body 32 is simultaneously raised to a height position where the article W is received and stopped (see FIG. 3).

  Next, the slider 33 is operated, and the transfer arm 34 moves forward toward the core material 29 of the article W and enters the core material 29. In this state, when the transfer arm 34 enters the core material 29, the dish-like recess 72A of the auxiliary arm 72 is positioned directly below the front support 27, where the lifting body 32 is placed in place. By raising the fixed amount, the article W is supported by the transfer arm 34 and the front support 27 is supported by the auxiliary arm 72 (see FIG. 5).

  Then, after the slider 33 is retracted and the article W is completely extracted from the rack device 11, the loader 12 returns to the initial position.

  When the loader 12 returns to the initial position, the slider 33 is actuated again to move to the loading / unloading lifter 14 side, and the rear extension 29B of the core material 29 is positioned above the rear receiving arm 78 and the front support 27 Is positioned above the front support arm 77, the elevating body 33 descends and the article W is placed on the loading / unloading lifter 14, and then the slider 33 moves backward to return the loader 12 to the initial position again. (See FIG. 6).

  Next, the entry / exit lifter 14 that has received the article W operates the elevating cylinder 80 to lower the portal frame 75, and places the article on a traveling body (not shown) that is waiting in advance below the portal frame 75. Thus, the article on the traveling body can be conveyed. In addition, the goods W are received by performing the above-described operations in reverse.

  Therefore, according to such an embodiment, since the transfer arm 34 is inserted into the core member 29 and the front support 27 is supported by the auxiliary arm 72, one end side of the article W is placed on the rack device. The storage form in which the other end side is positioned at the rear portion of the rack device 11 while being positioned at the front portion of the rack 11 can be employed. Therefore, it is possible to dramatically improve the storage efficiency compared to the case where the article is stored in a direction that crosses the forward / backward direction of the transfer arm 34. In addition, a design that facilitates preventing mutual interference of members when the article W is put in and out is possible. Further, since the articles W can be extracted with the amount of movement of the transfer arm 34 being within a range substantially smaller than the diameter of the roll, the articles W in each stage when the articles W are stored in the upper and lower stages Space can be minimized, and storage efficiency can be improved from this point.
