Description

  The present invention improves the material storage and storage device in a warehouse or the like, specifically, not only can the storage rate of the storage rack be improved, but also allows the material to be taken into and out of the storage rack efficiently and stably. In addition, the present invention relates to an overhead-type transport storage device that can easily perform maintenance, management, repair, and the like of a storage shelf, and an automatic storage / removal-type material storage using the same.

  As is well known, as a storage method in a material warehouse, a method of simply stacking and storing materials has been known for a long time, but under such a storage method, loading and unloading of materials can be done with a forklift or a hanging hook. Since it is necessary to carry out using an overhead crane or the like, it is difficult to efficiently store and take out materials due to an increase in human work.

  Therefore, conventionally, it is provided in storage shelves arranged side by side in the warehouse, travel rails installed above the storage shelves, parent carts that travel on the travel rails, slave carts that traverse the master cart, and slave carts. An overhead crane type stacker crane has been developed that can automatically store and take out materials using a box-shaped lifting guide and a transfer device mounted on the lifting guide (see Patent Document 1).

  However, with the conventional stacker crane described above, since the child carriage and the lifting guide are integrally provided, when the transfer device mounted on the lifting guide is moved between the storage shelves in different rows, the parent carriage is purposely stored. After taking out to the outside of the shelf, it was necessary to move the child cart and return the parent cart to the storage shelf again. For this reason, the material storage / removal work tends to be inefficient.

  In addition, conventionally, there is also known that the transfer device is hung with a wire below the child carriage and the length of the wire is adjusted so that the transfer device can be raised and lowered (Patent Literature). With regard to this technology, there was a risk that the transfer device hung with the wire would sway back and forth and left and right when the main and sub-carts were started and stopped, making the transportation unstable and the material falling.

  On the other hand, conventionally, a connecting frame that horizontally connects each stage of the traveling rail and the adjacent storage shelves on which the main carriage moves is provided at a predetermined interval, and a transfer device is provided at a position between the traveling rail and the fixed shelf of the connecting frame. A transport and storage device has also been developed in which guide columns for raising and lowering are fixed and the transfer device can move on the guide columns (see Patent Document 3).

  However, with regard to the above prior art, it is necessary to provide a large number of traveling rails, connecting frames, and guide posts, so that the equipment cost is likely to be high, and the traveling rails and guide posts are fixed even when the materials to be stored are changed. Since it was necessary to change the design along with the shelves, the cost burden was large. In addition, due to the large number of connecting frames and guide columns, it is difficult for people to enter the space between the fixed shelves, which makes it difficult to maintain and manage the fixed shelves.

  Furthermore, with regard to the above prior art, it was necessary to make the horizontal width (width between the vertical frames) of each storage section provided by dividing the width of the fixed shelf coincide with the width of the guide column. Even if it is small, it is difficult to reduce the lifting device below a certain size, and as a result, the lateral width of each storage unit must be determined according to the size of the lifting device.

  For this reason, the width of each storage section of the fixed shelf is considerably larger than the width of the material, resulting in an excessive space, and there is a problem that the storage rate of the fixed shelf decreases (for example, storage is performed with both ends supported). In the case of the roll material to be used, it is necessary to carry out and arrange the support member from both sides of each storage part to the inside, so that the storage space is reduced by the amount taken out).

JP-A-5-43018 JP 2000-203703 A Japanese Patent No. 2896475
