Description

  The present invention includes a lifting guide mast having a rectangular shape as viewed in the height direction provided along the height direction, and a pair of lifting side surfaces which are side surfaces arranged in the first direction and facing in opposite directions in the lifting guide mast. A pair of elevating bodies guided so as to be able to move up and down along, and the elevating guide mast is arranged at each of the rectangular corners and has four struts extending along the height direction. A pair of struts that connect adjacent struts to each other, and among the strut members, the pair of struts arranged in a second direction orthogonal to the first direction in the height direction view. The second strut member connecting between the second direction strut groups is a long member that connects portions of the same height in each strut constituting the second direction strut set and A plurality are provided apart from each other in the height direction. A transfer device for transferring an article to and from a transfer target position by moving an article support portion supporting an article to be transferred in a third direction different from the first direction in the height direction. The present invention relates to an article conveyance device provided.

As such an article transport device, the applicant, in Japanese Patent Application No. 2014-178314 (hereinafter referred to as a prior application), between each column of the first direction column set which is a pair of columns arranged in the first direction. It has been proposed that a member between struts to be connected is provided with a skewed portion connecting portions of different heights of a pair of struts constituting the first direction strut set in a posture inclined with respect to the height direction. The article transport apparatus according to the prior application is configured such that the article support portion is configured to be able to move in and out in a third direction different from the first direction in the height direction view, and is adjacent to the article support portion in the third direction. Articles are transferred to and from the target location.
Moreover, the article conveying apparatus according to the above prior application is provided with the skewed portion as described above, thereby suppressing the deformation of the lifting guide mast due to the force along the first direction.

However, even if the above-mentioned skewed portion is provided, the strength of the lifting guide mast in the first direction is greatly improved, but the strength of the lifting guide mast in the second direction is not improved as much as the strength in the first direction. . Therefore, when the article support part is moved in and out along the third direction, a moment along the circumferential direction is generated in the lifting guide mast in the height direction view, and the torsional deformation of the lifting guide mast in the height direction view is generated. It was easy to occur.
In addition, since the moment as described above changes depending on whether or not the article support part supports the article, the case of actual load (that is, the case where the article is wholesaled to the transfer target portion) and the case of empty load (that is, transfer) The magnitude of torsional deformation differs in the case of picking up an article from the target location. For this reason, there is a case where the protruding position of the article support section is displaced between the case where the article is wholesaled from the article support section and the case where the article support section picks up the article, which may hinder the transfer of the article.

  In view of this, an article transporting device is desired in which the torsional deformation of the lifting guide mast due to the withdrawal / withdrawal of the article support portion is unlikely to occur.

The article conveying device according to the present invention is provided along the height direction, and is a rectangular lifting guide mast that is rectangular in the height direction view, and a side surface that is aligned in the first direction and faces the opposite direction in the lifting guide mast. A pair of lifting bodies guided so as to be movable up and down along each of the pair of lifting side surfaces,
The elevating guide mast is arranged at each of the corners of the rectangular shape and extends along the height direction, and the struts that mutually connect adjacent struts among the four struts And connecting between the columns of the second-direction column set, which is a pair of columns arranged in the second direction orthogonal to the first direction in the height direction view among the members between the columns. A plurality of second strut members are provided with long members that connect portions of the same height in each strut constituting the second direction strut set and spaced apart in the height direction; The lifting and lowering body moves the article supporting portion that supports the article to be transferred in a third direction different from the first direction when viewed in the height direction to transfer the article to and from the place to be transferred. A transfer device for loading,
When viewed in the height direction, between the second strut members for each of the two second-direction strut groups arranged in the first direction, portions of different heights in the struts arranged in the second direction A second skew member is provided to connect the second skew member, and the second skew member and the second strut member are spaced apart in the first direction .

That is, the transfer device transfers the article to and from the transfer target location in a form in which the article support unit that supports the article is moved in and out in a third direction different from the first direction when viewed in the height direction. . For this reason, a moment along the circumferential direction is generated in the lifting guide mast in the height direction, and a force that causes torsional deformation is applied to the lifting guide mast.
According to this characteristic configuration, since the columns arranged in the second direction are connected at different heights, the strength against the force that causes torsional deformation in the lifting guide mast is improved, and twisting deformation hardly occurs in the lifting guide mast. .

  Therefore, according to this characteristic configuration, it is possible to provide an article transporting device in which the torsional deformation of the lifting guide mast accompanying the withdrawal / withdrawal of the article support portion hardly occurs.

Moreover , the member between 2nd support | pillars can be comprised so that the operator who performs the maintenance operation | work of an articles | goods conveying apparatus may also serve as the horizontal rail of the ladder which can be raised / lowered. By configuring in this way, for example, it is possible to reduce the number of members constituting the lifting guide mast, compared to the case where a ladder is attached as a separate body outside the outer side surface of the lifting guide mast, simplifying the configuration and weight Can be reduced in weight.
In such a configuration, by providing the second skew member and the second strut member spaced apart in the first direction, the operator can grasp the second strut member as a horizontal rail of the ladder, When a foot is put on the member between the second support columns, a situation where the second skew member and the operator's limb interfere with each other can be suppressed, and the worker can easily work.

  In the article conveying apparatus according to the present invention, it is preferable that the second skew member is composed of a pair of long members that are separated in the first direction.

  That is, in the second oblique member, it is the portion adjacent to the pair of lifting side surfaces in the lifting guide mast that contributes to the suppression of torsional deformation of the lifting guide mast as viewed in the height direction. When the portion separated from each of the lifting side surfaces (that is, the portion close to the midpoint of the pair of lifting side surfaces in the first direction) contributes little to the suppression of torsional deformation when the lifting guide mast is viewed in the height direction. Conceivable. Therefore, the second skew member is configured as a long member, and is disposed in a state of being spaced apart in the first direction by being close to each of the pair of lifting side surfaces, thereby twisting the lifting guide mast in the height direction. It is possible to reduce the weight by eliminating a portion that does not contribute to the suppression of deformation.

  In the article transporting apparatus according to the present invention, the first strut member connecting between the struts of the first direction strut group, which is a pair of struts arranged in the first direction, among the strut members, It is preferable that a skewed portion connecting portions of different heights of the columns arranged in the first direction in a posture inclined with respect to the height direction is provided.

That is, the force of the direction displaced in the direction along a 1st direction may act about a pair of support | pillar in a 1st direction support | pillar group.
According to this characteristic configuration, since the first inter-strut member connecting the struts of the first direction strut group is provided with the skew portion, the force in the first direction is applied as described above. Deformation of the lifting guide mast can be suppressed.

In the article transporting apparatus according to the present invention, the lifting guide mast is a portion of the four struts having the same height in a state where the relative positional relationship of the four struts in the height direction view is constant. It has a shape maintenance frame that connects each other,
It is preferable that the second oblique member is configured to connect portions adjacent to the side surfaces facing in the second direction in the shape maintaining frames adjacent in the height direction.

That is, since the relative position in the height direction of the four columns in the lifting guide mast is maintained by the shape maintaining frame, the lifting guide mast in which the four columns are separated from each other or approach each other. Can be suppressed.
In addition, by connecting the shape maintaining frames adjacent to each other with the second skew member, it is not necessary to separately provide a member for connecting the second skew member to the support column, thereby simplifying the configuration. Can do.

  In the article conveying apparatus according to the present invention, the second skew members adjacent in the vertical direction are provided such that the directions inclined from the height direction to the second direction are opposite to each other. It is preferable.

  That is, when the second oblique members adjacent to each other in the vertical direction are arranged so that the directions inclined from the height direction to the second direction are the same, the lifting guide mast is twisted as viewed in the height direction. The direction of the second skew member is aligned with the direction of the force that causes the deformation. On the other hand, the direction of the force that causes the torsional deformation is considered to change depending on the environment such as the movement of the article support part and is not always a constant direction. It is also conceivable that the second oblique member is in an arrangement state in which it is difficult to generate a resistance against the force.

  According to this characteristic configuration, adjacent ones of the second skew members in the vertical direction are arranged so that the directions inclined from the height direction to the second direction are opposite to each other, and thus torsional deformation occurs. No matter how the direction of the force causing the change occurs, any of the second oblique members having different inclination directions is likely to generate a resistance against the force causing the torsional deformation. Can be expected.

  In the article transport device according to the present invention, the elevating guide mast is provided in a traveling carriage that travels along a travel route along the first direction, and a storage unit that stores the article serves as the transfer target portion. A plurality of the carriages are provided side by side in the traveling direction and the height direction of the traveling carriage, and the third direction and the second direction are the same direction, and the article support portion protrudes in the second direction. It is preferable that the article is configured to be retracted and transferred to and from the storage unit.

  In other words, the article support portion moves in and out along a second direction perpendicular to the first direction as viewed in the height direction so as to transfer the article to and from a storage portion provided on the side of the travel route of the traveling carriage. Moving. At this time, a moment around the lifting guide mast is generated, and a force that causes twisting of the lifting guide mast is applied. Further, in the case where the storage units are provided on both sides of the travel route, the transfer devices of the pair of lifting bodies simultaneously eject the article support units from the side storage units having different travel routes. When retracted, it is conceivable that the magnitude of the force generated by the moment to cause the lifting guide mast to twist is increased. Even in such a case, since the second skew member suppresses the force that causes the twist in the lifting guide mast, the situation in which the twisting deformation occurs in the lifting guide mast can be appropriately suppressed.
