Description

  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 apparatus shown in the document includes a rack device that supports a roll-shaped article and a crane that loads and removes the article with respect to the rack apparatus. The roll-shaped article is provided in such a length that both end portions of the core member protrude from both ends in the width direction of the roll, and the rack device includes a pair of support members that respectively support the protruding portions of the core member. It has been adopted. On the other hand, the crane includes a slide provided so as to be able to advance and retreat with respect to the position of the support member, and an article receiver provided on the slide, and raises and lowers the article receiver so as not to interfere with the support member. As a result, the article can be taken out while supporting both ends of the core material supported by the support member, while the article can be stored in the rack device by performing the opposite operation.

JP-A-9-118404

However, in the loading / unloading apparatus described in Patent Document 1, the support member is configured to support the protruding portion of the core material in a state in which the core material is protruded from both ends of the article. There is an inconvenience that the storage volume is reduced according to the length.
The apparatus of Patent Document 1 cannot be applied to an article that uses a core material that fits within the width of a strip material such as film or paper, and has a longer axis size than the width of the strip material. If the core material is required and the length does not have a certain standard, it cannot be applied. This is because the article is supported on both sides when the article is put in and out.
Moreover, in such a loading / unloading device based on such a dual-supported structure, a pair of members that support the core material must be arranged, which causes a complicated structure of the device.

[Object of invention]
The present invention has been devised by paying attention to such inconveniences, and its purpose is not to use a core material that is longer than the roll width, and to efficiently use the space. An object of the present invention is to provide a loading / unloading apparatus capable of achieving simplification of the structure of each part of the apparatus.

In order to achieve the above object, the present invention provides a loading / unloading system including a rack device that stores a roll-shaped article having a cylindrical space at the center, and a loader that loads and removes the article with respect to the rack device. In the device
The rack device includes a support arm that extends into the cylindrical space to keep the article in a storage position and supports the article in a cantilever state, while the loader advances and retreats with respect to the article storage position. A possible slider, and a transfer arm that is supported by the slider in a cantilevered posture and provided so as to be able to advance and retreat with respect to the cylindrical space without interfering with the support arm,
The transfer arm extends in the horizontal direction, the opposite end of the transfer arm to the free end is fixed to the slider, is provided with a shape having a substantially U-shaped groove, and a plurality of elastic members are attached to the upper edge. Configured,
By adopting a configuration in which the transfer arm and the support arm are moved relative to each other, an article can be provided in and out of the storage position.

Furthermore, the present invention stores a roll-shaped article having a cylindrical space in the center, and is laid on a floor surface between a pair of rack devices oriented in the direction in which the loading / unloading side faces each other. A guide rail and a loader provided to be movable along the guide rail,
Each of the rack devices includes a plurality of support arms that support the article in a cantilevered posture with the axial direction one end side of the article facing the opposite rack apparatus side at predetermined intervals in the vertical and horizontal directions,
The loader includes a loader body that is movable along the guide rail, a lifting body that can be moved up and down on the loader body, a rotating body that is rotatably supported by the lifting body in a plane, and the rotation A slider which is supported by the body and provided so as to be able to advance and retreat with respect to the article,
The slider includes a transfer arm that can move back and forth without interfering with the support arm with respect to the cylindrical space,
The transfer arm extends in the horizontal direction, is supported by the slider in a cantilevered manner , is fixed to the slider on the opposite side of the free end, is provided with a shape having a substantially U-shaped groove, and has an upper end edge. A plurality of elastic members are attached and configured.
By positioning each arm in the cylindrical space so that either one of the transfer arm or the support arm receives the other and moving each arm in the vertical direction, the article is supported by the support arm. It is configured such that it can be transferred to the arm or removed from the support arm.

  According to the present invention, since the support arm in the rack device is configured to support a roll-shaped article in a cantilever state, the article can be supported if there is a cylindrical space in the center of the article. It is possible to eliminate the need to use a core material having a length that protrudes outward from both ends in the width direction of the article, and the storage efficiency can be improved correspondingly. And since it is the structure which should just form a fixed cylindrical space in the center of a roll, the application to the articles wound by roll shape without using a core material is not prevented.

  Further, the support arm and the transfer arm can adopt a configuration that can be simultaneously positioned in the cylindrical space of the article so that one of the support arm and the transfer arm overlap each other in a state of receiving the other. For example, when the transfer arm has a U-shaped cross-sectional shape, the support arm can be designed as a shaft-like member that can be positioned inside the U-shape, and can receive an article or The delivery structure can be made extremely simple. In this case, when the transfer arm moves to a position for receiving the support arm while the support arm is supporting the article, the transfer arm is supported by the transfer arm by slightly raising the transfer arm. It can be changed. Therefore, in this state, the article can be easily taken out from the storage position by retracting the transfer arm.

  Thus, according to the present invention, the transfer arm can be moved relative to the support arm in the axial direction, and an article can be taken in and out if there is a space that can be moved slightly in the vertical direction. it can. Therefore, a large number of articles can be stored in the rack apparatus in a state of being close to each other, and articles can be taken in and out as long as a space allowing the relative movement is secured in the cylindrical space. It is possible to realize the maximum use of the storage space for the articles.
