DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article transfer position for each of a plurality of article holders positioned in parallel in the vertical and horizontal directions, and for transferring articles between the article holder and the self. The present invention relates to an article storage facility in which an article transfer device for loading is vertically operable and supported by the horizontally long elevating frame so as to move in the lateral direction.

[0002]

2. Description of the Related Art Such an article storage facility has a structure in which an article holding unit arranged in a state of being arranged in a vertical direction and a lateral direction is arranged.
Articles are transferred by an article transfer device, and articles can be taken in and out of each article holding unit.
In addition, since the article holding units are arranged in a state of being arranged in the up-down direction and the horizontal direction, in order for the article transferring apparatus to transfer the articles to and from the article holding unit, the article transferring apparatus is required to store the articles. The part transfer device is moved to the article transfer position with respect to each article holding unit by moving the apparatus vertically by supporting the unit in a laterally long elevating frame that is arranged side by side and moving the elevating frame up and down. Let it.

[0003] In the configuration in which the article is transferred to and from the article holding unit by the article transferring apparatus and the article is conveyed,
For example, when compared with a configuration in which articles are transferred and transported by a so-called stacker crane, especially when the length of the article holding portions in the horizontal direction is long, the entire traveling body having the lifting mechanism is provided by the stacker crane. Need to be moved, so that the weight of the moving part becomes large.On the other hand, by adopting a structure in which the article transfer device is supported and moved by the lifting frame, the weight of the part that is It can be small and can be moved at high speed. By the way, the elevating frame supporting the article transfer device as described above conventionally forms a main body portion for supporting the article transfer device movably in the lateral direction with a long and single component member. Was common.

[0004]

However, in the above-mentioned conventional configuration, it is necessary to form the above-mentioned single component member to have a strength necessary for supporting the article transfer device and to be long. In addition, there has been an inconvenience that the manufacturing cost increases due to an increase in the size of the manufacturing apparatus. In order to avoid such inconveniences, it is conceivable to form a lifting frame by connecting relatively short components, but since the strength of the connecting portion tends to be insufficient, the lifting operation of the lifting frame is performed. In addition, there is a possibility that the moving operation of the article transfer device becomes unstable, and conversely, if the strength of the connecting portion is increased, the structure of the lifting frame becomes complicated, which leads to an increase in manufacturing cost. The present invention has been made in view of the above circumstances, and has as its object to reduce manufacturing costs as much as possible while ensuring high-speed and stable operation of an article storage facility.

[0005]

According to the first aspect of the present invention, a long elevating frame supporting the article transfer device is connected to a plurality of divided frame portions along the longitudinal direction. When the elevating frame is operated to move up and down, the operating force of the elevating drive means is applied to the connecting portion of the frame portion and the portion separated therefrom to move up and down. Therefore, the force applied to the connecting portion of the frame portion is reduced by the load of the lifting frame itself, the load of the article transfer device supported by the lifting frame, and the like, so that the durability of the lifting frame is improved and the lifting frame is improved. And the stability of the moving operation of the article transfer device can be improved, and the manufacturing cost can be reduced as much as possible while ensuring the high-speed and stable operation of the article storage facility.

According to the second aspect of the present invention, a plurality of elevating guide columns are erected on the ground side so as to guide the elevating frame up and down freely. Is provided with an article storage shelf provided in the article holding unit. Therefore, it is possible to suppress the lifting guide pillars from protruding in the lateral movement path of the article transfer device, and it is possible that the degree of freedom of design of the article transfer device is limited by the presence of the lifting guide pillars. This can be avoided, and can be advantageous in terms of implementation. In addition, since both ends of the lifting frame and the connecting portion of the adjacent frame portion are guided by the lifting guide columns, the lifting operation force and the force for the lifting guide are concentrated on the connecting portion of the frame portion. In addition, the operation of the article storage facility can be further stabilized.

[0007] Further, by providing the structure of the third aspect, an urging force acts upward on the connection between both ends of the lifting frame and the adjacent frame portion by the balance weight. Therefore, the driving force required for raising and lowering the lifting frame is reduced, and the mechanism for raising and lowering the lifting frame can be simplified.

In addition, with the above configuration, the lifting frame is raised and lowered by the lifting and lowering operation of the lifting operation body connected to the connecting portion of the frame portion by the driving device. As the elevating frame moves up and down, the rotary articulation body provided at a location close to the connection point of the elevating operation body rotates due to relative movement with the occluded body installed along the elevating path of the elevating frame. Then, the rotating bite body, which is interlocked and connected so as to rotate integrally with the rotary bite body, rotates, and moves relative to the bite body with which the rotary bite bites. As a result, the elevating operation force is transmitted to a position distant in the longitudinal direction of the elevating frame from the connection point of the elevating operation body. , The change in the posture of the lifting frame with time can be reduced, and the lifting frame can be maintained in the proper posture over a long period of use.

Further, by providing the structure according to claim 5, a balance weight for urging the lifting frame upward is connected to a plurality of positions in the longitudinal direction of the lifting frame.
The load on the lifting / lowering driving means can be reduced in a well-balanced manner in the longitudinal direction of the lifting / lowering frame, so that the structure of the lifting / lowering driving means can be simplified and the lifting / lowering operation of the lifting / lowering frame can be further stabilized.

[0010] With the above construction, the rotating endless body connected to the elevating frame is driven by the driving device to wind up and down the elevating frame. A balance weight for urging the frame upward is attached to the rotating endless body. Therefore, the configuration for providing the balance weight and the configuration for operating the lifting frame up and down can be shared, and the configuration can be simplified. Moreover, the balance weight attached to the rotating endless body as a lifting / lowering operation body is a part of a plurality of ones, but the remaining balance weights are also attached to the rotating endless body for supporting the balance weight, thereby supporting a plurality of balance weights. The configuration is unified, and the configuration can be simplified also in this regard.

[0011] With the above structure, when the lifting frame is moved up and down by a driving force acting on the connecting portion of the lifting frame with the lifting operation body, the pinion is interlocked via the rotating shaft. In this state, it rotates due to relative displacement with the rack. Therefore, the pinion is accurately rotated by the elevating movement of the elevating frame, and its driving force is accurately transmitted to the other pinions via the rotating shaft, and the elevating frame moves up and down smoothly while maintaining the proper posture, It is possible to suppress a temporal change in the posture of the lifting frame. Thus, the labor required for facility management can be reduced while simplifying the configuration as much as possible.

In addition, by providing the above structure, a timing belt is connected to the lifting frame as a rotating endless body, and the lifting belt is driven up and down, and the driving force is accurately transmitted to the driving device to the lifting frame. . A fixed tension pulley is provided on the portion of the endless rotating body constituted by the timing belt that is on the tension side due to the load of the lifting frame, and the portion on the loose side is elastically pressed against the rotating endless body. A biased movable tension pulley is provided. In other words, the necessary tension is applied on the tension side to properly transmit the lifting drive force of the lifting frame, and on the loose side, an appropriate tension is maintained by the movable tension pulley to absorb the elongation of the timing belt. Thus, the driving of the lifting frame by the driving device can be accurately performed.

[0013] Further, by providing the configuration according to the ninth aspect, the article transfer device supported in the elevating frame so as to be movable in the lateral direction can be a timing belt for lateral movement wound in the lateral direction of the article storage shelf. And is driven in a lateral direction by a winding drive of a lateral movement timing belt by a lateral drive motor. Accordingly, the driving force of the lateral drive motor is reliably transmitted by the lateral timing belt, and the lateral movement of the article transfer device can be accurately performed even in the vertically long lifting frame. .

According to the tenth aspect of the present invention, the lateral movement of the article transfer device is driven by the winding drive of the lateral timing belt as described above. The lateral movement timing belt is tensioned by a pulley which is urged toward the tension side by an air cylinder. In other words, the timing belt for lateral movement becomes longer as the lifting frame is longer in the horizontal direction, so the tension that needs to be applied to the timing belt for lateral movement also becomes larger, but this tension is attached to the air cylinder. By applying the force, it is possible to reduce the size of the apparatus while securely applying the tension, as compared with a case where the tension is applied by a normal urging means such as a spring.

In addition, with the configuration according to the eleventh aspect, the article transfer device is supported by the lifting frame in the suspended state and guided for traveling. The lifting frame is provided with a rotatable articulated body and a mechanism for interlockingly connecting the rotatable articulated body with an articulated body provided in the elevating path of the elevating frame, and further, for operating the elevating frame vertically Are connected. Therefore, due to the existence of the rotary bite, the structure for movably supporting the article transfer device on the lifting frame is limited. In such a case, by allowing the article transfer device to be guided while being suspended from the lifting frame, it is possible to stably support the article transfer device while avoiding interference with many objects. It can be easy,
This can be advantageous in terms of practical production.
