[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. As a configuration for raising and lowering the lifting frame, a configuration in which both ends in the longitudinal direction of the lifting frame are suspended and supported by a pair of wires and the pair of wires are collectively wound and driven has been considered. .

[0003]

However, in the above-described conventional configuration, the lifting frame may be tilted from an appropriate posture due to a difference in wire extension between the pair of wires, and the tilt is corrected. Maintenance work is required, and the management of the equipment requires time and effort.
Also, in order to make such maintenance work unnecessary, the above-mentioned pair of wires can be separately wound and driven, and a sensor for detecting the height of both ends in the longitudinal direction of the lifting frame, A configuration in which a pair of wires are separately wound and driven so that the heights of both ends in the longitudinal direction of the elevating frame maintain a predetermined height is also conceivable, but a complicated mechanism is required and the manufacturing cost is increased. There are inconveniences. The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the labor required for facility management while simplifying the configuration as much as possible.

[0004]

According to the first aspect of the present invention, the lifting frame is raised and lowered by the lifting and lowering operation of a lifting and lowering operation body connected to a specific portion thereof by a driving device. The lifting frame is provided with a rotary bite body that is interlockingly connected so as to rotate integrally with each other at a position adjacent to the connection position of the lifting operation body and at a position separated from the position in the longitudinal direction of the lifting frame. The occlusal object that can be engaged with each of these rotary articulation bodies is installed along the elevating path of, and the elevating drive force acts on the connection point of the elevating frame with the elevating operation body, and the elevating frame moves up and down When moved, the rotary bite rotates in a linked state due to relative displacement with the bite. That is, even if a vertical driving force is applied to the vertical frame with respect to the vertical frame in response to a request to reduce the number of installed driving devices, the vertical driving force is transmitted by the interlocking of the rotating bite, and the vertical driving force is transmitted. As the frame moves up and down smoothly while maintaining the proper posture, and the rotating bite is interlockingly connected so as to rotate integrally, this interlocking state changes over time as compared with, for example, hanging support by a cord-like body. Since the number can be reduced, it is possible to suppress the temporal change of the posture of the lifting frame. Thus, the labor required for facility management can be reduced while simplifying the configuration as much as possible.

[0005] Further, by providing the structure according to the second aspect, the lifting drive force from the lifting operation body acts on one end of the lifting frame, and the structure of the driving device for raising and lowering the lifting operation body. Simplification can be achieved. However, an extremely biased driving force acts in the longitudinal direction of the lifting frame,
Even in this case, the rotary occlusion bodies arranged at both ends of the lifting frame are interlocked, the lifting driving force is transmitted, and the lifting frame moves up and down smoothly while maintaining the proper posture, and the rotary bite body is Since the interlocking connection is made so as to rotate integrally, the interlocking state can have little change with time, so that the change of the attitude of the lifting frame with time can be suppressed. Thus, the labor required for facility management can be reduced while simplifying the configuration as much as possible.

In addition, with the above-described structure, a plurality of lifting operation bodies are connected to the lifting frame, and the lifting operation is performed at a plurality of positions in the longitudinal direction. In this case, in correspondence with each of the plurality of lifting operation bodies, a set of rotary bite bodies that are linked and connected so as to rotate integrally is provided, and the lifting frame maintains an appropriate posture for each pair. Works. Therefore, the lifting drive force is applied to the lifting frame in a distributed manner, and the proper posture of the lifting frame is maintained by a set of a plurality of rotary occluding bodies. You can avoid overloading your body,
The lifting frame can be smoothly raised and lowered while simplifying the configuration.

Further, by providing the above structure, an upward force is applied to the lifting frame by the balance weight, so that the load applied to the driving device via the lifting operation body is reduced and the rotation is reduced. The load of the lift frame acting as a load on the integral rotation of the bite body is also reduced. Thus, it is possible to smoothly perform the lifting operation of the lifting frame while reducing the size of the driving device and the like.

In addition, by providing the structure according to the fifth aspect of the present invention, the lifting frame is moved up and down by driving the rotating endless body connected to the lifting frame by a driving device. 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.

According to the sixth aspect of the present invention, a plurality of elevating guide columns are erected on the ground side to guide the elevating frame up and down freely. Is provided with an article holding section. 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.

[0010] With the above structure, when a lifting drive force acts on the connecting portion of the lifting frame with the lifting operation body and the lifting frame moves up and down, 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.

[0011] Further, with the structure of the eighth aspect, 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.

According to the ninth aspect of the present invention, there is provided an article transfer device supported on a lifting frame so as to be movable in a lateral direction, a timing belt for lateral movement wound in a lateral direction of an 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.
