Description

  The present invention relates to a traveling carriage that travels along a traveling route, an elevating guide mast that is fixed to the traveling carriage and is erected along a height direction, and an article conveyance that moves up and down as guided by the elevating guide mast. An elevating body, and the elevating guide mast includes a columnar portion having a polygonal columnar outer shape, and the columnar portion is disposed in each of the corners of the polygonal shape as viewed in the height direction and extends along the height direction. The present invention relates to an article transporting apparatus including a plurality of struts extending and a connecting portion that connects a pair of adjacent struts among the plurality of struts.

  As such an article conveyance device, Japanese Patent Application Laid-Open No. 2003-267516 (Patent Document 1) describes a device provided with a lifting guide mast formed of a cylindrical body having a polygonal outer shape. In such a lifting guide mast, a force along the direction in which the traveling direction of the traveling carriage extends (hereinafter referred to as a traveling direction load) acts as the traveling carriage travels. For this reason, it is necessary to increase the strength of the side surface (hereinafter referred to as the traveling direction side surface) extending along the traveling direction of the traveling carriage in the cylindrical lifting guide mast with respect to the traveling direction load. As a countermeasure, it is conceivable to increase the thickness of the plate-like body constituting the traveling direction side surface. However, when such a configuration is adopted, there arises a problem that the weight of the lifting guide mast becomes heavy. This problem is conspicuous when forming a high elevation guide mast.

  Therefore, as in Japanese Patent Application Laid-Open No. 2009-113907 (Patent Document 2), the elevating guide mast is configured to include a plurality of support columns and a connecting member that connects adjacent columns among the support columns. Has been proposed. In order to increase the strength of the lifting guide mast with respect to the traveling direction load, the lifting guide mast in the article conveying device of Patent Document 2 serves as a connecting portion that connects a pair of supporting columns that constitute the side surface in the traveling direction. A plurality of elongated skew members that connect between different heights of one and the other of the pair of struts are attached between them. Further, the oblique members adjacent to each other in the vertical direction are attached so as to have different postures, either an inclined posture in which one side of the column is a high position or an inclined posture in which the other side of the column is a high position.

  However, since the lifting guide mast in the article conveying apparatus of Patent Document 2 has a configuration in which a plurality of skew members are separately attached between a pair of support columns constituting the traveling direction side surface, the strength against the traveling direction load is strong. The manufacture of the lifting guide mast has been complicated.

  Therefore, it has been desired to realize an article conveying apparatus including an elevating guide mast that has high strength against a load in the traveling direction while suppressing complication of production work.

In order to solve the above problems, an article transporting apparatus according to the present invention includes a traveling carriage that travels along a traveling route, a lifting guide mast that is fixed to the traveling carriage and is erected along a height direction, and the lifting guide. A lifting / lowering body for conveying articles that is guided by the mast, and the lifting / lowering guiding mast includes a columnar portion having a polygonal columnar outer shape, and the columnar portion has a polygonal corner when viewed in the height direction. An article conveying apparatus comprising: a plurality of struts arranged in each of the sections and extending along a height direction; and a connecting portion that couples a pair of adjacent struts among the plurality of struts. ,
Of the side surfaces of the columnar portion, a side surface extending along the traveling direction of the traveling carriage is a traveling direction side surface, and the connecting portion provided between a pair of support columns forming the traveling direction side surface is connected in the traveling direction. The travel direction connecting portion includes a plate-like body extending along the side surface in the travel direction and a pair of side edges extending along the height direction on both sides of the plate-like body in the travel direction. A fixing portion that fixes each of the portions to a corresponding strut of the pair of struts, and the plate-like body has a portion protruding in the thickness direction of the plate-like body. A protrusion extending in a belt shape along the surface, and the protrusion is arranged in a polygonal line that meanders alternately between the different heights of one of the pair of struts and the other. It is characterized by that.

  The traveling direction coupling portion that couples the pair of support columns arranged in the traveling direction has a plate-like body, and the pair of side edge portions of the plate-like body are fixed to the pair of support columns by the fixing portion. A pair of struts are connected by a plate-like body. And in the plate-like body, the protruding portion extending in a strip shape along the plate surface in the portion protruding in the thickness direction of the plate-like body is a portion of a portion having a different height between one of the pair of struts and the other. Since it is arranged in the form of a polygonal line that meanders alternately, the strength against the force in the direction along the ridges in the plate-like body is improved, and the portions of the pair of struts are alternately located at different heights. As in the case where the diagonal member connected to the fixed member is provided, the strength against the traveling direction load can be increased.

Since a plurality of protrusions can be formed on a single plate-like body, the number of members attached to each of the pair of struts as compared to the case of attaching a plurality of diagonal members to each of the pair of struts separately Can be reduced. For this reason, the operation | work which manufactures a raising / lowering guide mast can be simplified.
Therefore, it is possible to realize an article conveying apparatus including a lifting guide mast having a strong strength against a traveling direction load while suppressing complication of production work.

  In the article transporting apparatus according to the present invention, the plate-like body forms an opening penetrating the plate-like body in the thickness direction in a non-existing region where the protruding portion does not exist. It is preferable to provide.

  That is, even if an opening that penetrates the plate-like body in the thickness direction is formed in a non-existing region where the protruding portion does not exist, the presence of the protruding portion ensures the strength against the traveling direction load. be able to. Therefore, by forming the opening forming portion in the non-existing region, it is possible to provide a traveling direction connecting portion that is as light as possible while providing strength against the traveling direction load.

  In the article conveying apparatus according to the present invention, it is preferable that the traveling direction connecting portion is configured by arranging a plurality of the plate-like bodies in the height direction of the pair of support columns.

  That is, when the traveling direction connecting portion is configured by one plate-like body in the height direction of the pair of support columns, the plate-like body extending over the entire height at which the traveling direction connecting portion is required in the height direction of the pair of support columns. For this reason, the plate-like body becomes large, and it becomes difficult to manufacture, transport, and attach the plate-like body. On the other hand, according to this characteristic configuration, the plate-like body can be made shorter than the total height of the height where the traveling direction connecting portion is required, so that the plate-like body can be downsized. The production, transportation and mounting of the plate-like body are facilitated.

  In the article conveying apparatus according to the present invention, each of the pair of side edge portions of the plate-like body includes a pair of end surfaces extending along a plane orthogonal to the traveling direction, The first support column that is one of the first support columns includes a first contact surface that extends along the height direction and contacts a first end surface that is one of the end surfaces of the plate-like body, and the pair of support columns The second support column, which is the other of the two, has a second contact surface that extends along the height direction and contacts the second end surface that is the other of the end surfaces of the plate-like body. Is preferred.

  That is, as the traveling carriage travels, a force that is displaced in a direction along the direction extending in the traveling direction may act on the plate-like body in a direction extending in the traveling direction. At this time, the movement of the plate-shaped body in the direction in which the plate-shaped body and the first support column approach each other is caused by the first contact surface formed on the first support column and the first end surface of the plate-shaped body contacting each other. It is suppressed. Further, the movement of the plate-like body in the direction in which the plate-like body and the second support column approach each other is suppressed by the contact between the second contact surface formed on the second support column and the second end surface of the plate-like body. Is done. Thus, the displacement of the plate-like body with respect to the pair of support columns in the direction along the direction extending in the traveling direction can be appropriately suppressed.

In the article conveying apparatus according to the present invention, the first support column includes a first side edge contact surface that contacts a surface in the first thickness direction, which is one side of the side edge in the thickness direction. And the first contact surface is formed on a first contact surface forming portion that protrudes from the first side edge contact surface to the thickness second direction side opposite to the thickness first direction side. A direction that is formed and further toward the second strut side toward the second strut side with respect to the second strut side than the first abutment face forming portion at the first side edge abutment surface. A first inclined surface that is inclined so as to extend along the height direction,
The second support column includes a second side edge contact surface that contacts the surface of the side edge portion on the thickness first direction side, and the thickness of the second support column is increased from the second side edge contact surface. The second abutment surface is formed in a second abutment surface forming portion that protrudes in the two-direction side, and further, the first strut is more than the second abutment surface formation portion in the second side edge abutment surface. It is preferable that the 2nd inclined surface which inclines in the direction which goes to the said thickness 2nd direction side toward the said 1st support | pillar side is formed so that it may extend along a height direction.

  That is, in a state in which the plate-like body is attached to the pair of columns, the plate-like body is in contact with the first contact surface and the first end surface of the plate-like body, and the second inclined surface and the plate of the second column. The movement of the first support column and the second support column toward the first support column in the arrangement direction of the first support column and the second support column is suppressed by the contact with the surface along the second inclined surface of the cylindrical body. Further, in a state where the plate-like body is attached to the pair of support columns, the plate-like body is in contact with the second contact surface and the second end surface of the plate-like body, and the first inclined surface and the plate of the first support column. Due to the contact with the surface along the first inclined surface of the cylindrical body, the movement of the first support column and the second support column to the second support column side is suppressed. Thus, a plate-like body can be attached to the first support column and the second support column in a state where the position is fixed.
