Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluidized shelf applied when a load is supplied from one side and taken out from the other side in, for example, an assembly line of a factory or a warehouse, and in particular, an upper surface of an inclined shelf member. The present invention relates to a fluidized shelf in which a load is made to flow along the slope by its own weight.

[0002]

2. Description of the Related Art In general, a fluidized shelf of this type supports a plurality of stages of shelf members whose upper surface is a sliding surface by a large number of rollers or the like on a plurality of columns of a support frame arranged at intervals with a constant inclination angle. It has been configured.

Such a fluidized shelf can be constructed relatively easily by using an angle member and the like, and the effective utilization of the installation space is high, and the load supplied from the upper side of the shelf member is high. It can be moved to the lower side by its own weight and can be stored in a densely aligned state without gaps, and can be easily taken out from the lower side as needed, so it can be used for a wide range, such as storing a large number of the same type of items or compartments of different types of items. It's being used.

[0004]

By the way, in the conventional fluidized shelves, it is difficult to cope with a change in the required yield and a change in the installation location of the fluidized shelves. That is, a fluidized shelf is generally
From the viewpoint of effective use of constituent materials and improvement of storage efficiency,
The shelf member is composed of, for example, a rectangular frame-shaped shelf frame and a large number of vertical rails with rollers arranged in parallel along the inclination direction of the shelf frame. Then, in consideration of convenience of installation, etc., a plurality of notches formed at the lower edges of both side frame portions along the direction orthogonal to the inclination direction are detachably hooked to the support pins protruding from the columns, respectively. It has been configured.

In such a structure, for example, when the length of the shelf member in the inclined direction is increased in order to increase the required yield, the vertical frame portion of the shelf frame is bent, and the notch formed at the lower end edge thereof and this are formed. Between the support pin that locks, the gap is generated especially on the upper end side, and the locking state becomes uneven,
This may cause rattling of the shelf member.

Therefore, for example, Japanese Utility Model Publication No. 60-38580
As described in the publication, various dimensions such as improving the depth and width of the notch of the shelf frame to give a certain degree of freedom to the latching portion to stabilize the shelf frame support, etc. Technical improvements have been made.

However, the use range of the fluidized frame is wide as described above, and various types of fluidized shelves, such as a large size or a small size, can be used in accordance with changes in the size and yield of the articles to be accommodated, the use, the installation space and the like. In many cases, it is necessary to change the size to use it, but so far, only the measures for larger size have been taken as described above, and the depth of the fluidized shelf considering the miniaturization etc. Changes are not always adequately addressed.

The present invention has been made in view of such circumstances, and an object thereof is to flexibly adjust the depth of the shelf member in response to a change in required yield, a change in installation location of a fluidized shelf, or the like. It is to provide a changeable articulated flow rack.

Another object of the present invention is to make it possible to easily and smoothly connect and separate the shelf members when changing the depth of the fluidized shelves, and to connect a plurality of shelves at the time of connection. To make it possible to stably support the shelf members on the columns without rattling, and to prevent shifting in the vertical direction and the lateral direction so that the connecting portions of the shelf members are smooth without steps. Or, even if there is a slight dimensional variation in parts manufacturing in a configuration having several sub-tiered shelf members, unevenness in the tilt direction due to that can be absorbed independently for each step and there is no problem in using each step. Is to be able to do it.

[0010]

In order to achieve the above-mentioned object, the invention of claim 1 supports a shelf member whose upper surface is a sliding surface at a fixed inclination angle on a plurality of columns arranged at intervals. In the fluidized shelf in which the load is placed on the shelf member so that the load can flow by its own weight, the shelf member has a connecting structure in which a plurality of shelf member elements are butted so as to be contactable and separable along the inclination direction, and It is characterized in that at least two locations on both sides of the shelf member element along at least the slanting direction are detachably supported by the column respectively.

According to a second aspect of the present invention, in the fluidized shelf according to the first aspect, each of the shelf member elements has at least two notches formed at lower edges along the inclination direction of both side portions on a support pin protruding from a column. One notch at the same height position on both sides of the shelf member element located at the lowermost end of the shelf member element is hooked at a fixed position in the inclination direction with respect to the support fitting. In addition to the narrow notch, the other notch of the same element is a wide notch which has a certain degree of freedom in the inclination direction and is hooked to the support fitting, and is provided on the upper side other than the same element. The notches of the other shelf member elements located are all wide notches having a certain degree of freedom in the inclination direction and hooked on the support fitting.

According to a third aspect of the present invention, in the fluidized shelf of the first or second aspect, among the pair of shelf member elements connected to each other along the inclination direction, the upper end of the shelf member element located in the lower direction in the inclination direction. The edge portion and the lower end edge portion in the inclined direction of the shelf member element located on the upper side are a concave portion having an acute-angled cross-section opened in the up-down direction provided on either one of them and a corresponding convex portion provided on the other. It is characterized in that the upper and lower surfaces are aligned and connected by fitting with the parts.

According to a fourth aspect of the present invention, in the fluidized shelf according to any one of the first to third aspects, the shelf located at the lower side of the pair of shelf member elements connected to each other along the inclination direction. One of the upper end edge in the inclination direction of the member element and the lower end edge in the inclination direction of the shelf member element located on the upper side has a guide piece that expands outward at a constant angle from both side edges orthogonal to the inclination direction. However, by guiding the other shelf member to the inside of this guide piece, both shelf member elements are connected with their side edges orthogonal to the tilt direction aligned.

[0014]

According to the first aspect of the present invention, when the required yield is increased, a plurality of shelf member elements are butt-connected along the tilt direction, whereby the depth dimension along the tilt direction can be enlarged. Further, when the required yield is reduced or when the space at the installation location of the fluidized shelf is small, by separating the connected shelf members, the depth dimension along the inclination direction can be reduced. Therefore, it is possible to flexibly change the depth of the shelf member in response to a change in the required yield, a change in the installation location of the fluidized shelf, or the like.

Further, each shelf member element is detachably supported at at least two positions on both sides along a direction orthogonal to the inclination direction so that each shelf member is detachably supported at the time of expanding and contracting the depth dimension. In any of the above, it can be made stable, and the switching operation can be easily performed.

According to the second aspect of the present invention, the shelf member element located at the lowermost end is hooked on the support fitting through the narrow cutout at a fixed position in the inclination direction, and the other wide cutouts correspond. It is possible to hang it on the supporting metal fitting having a degree of freedom along the inclination direction. Further, the other shelf member elements located on the upper side have a certain degree of freedom by means of all the wide cutouts and are respectively hooked on the support fittings, so that the shelf member element at the lowermost end previously installed at a fixed position is removed. As a reference, the lower shelving member elements can be sequentially butted and connected. In this case, the degree of freedom of the notch of the other shelf member element located on the upper side is preferably set such that the upper end of the notch matches the position of the support fitting when the shelf member element on the lower side is abutted. . With such a configuration, when connecting the shelf member elements to increase the depth dimension along the inclination direction, the shelf member located on the upper side is fixedly mounted along the inclination direction with reference to the shelf member located on the lower side. It is possible to stably and smoothly support the plurality of shelf members in a good continuous state and to stably support them on the column without rattling. On the contrary, the work for separating can also be easily and smoothly performed with a certain degree of freedom along the inclination direction.

According to the third aspect of the present invention, the upper end edge of the shelf member element located on the lower side in the inclined direction and the lower end edge part of the shelf member element located on the upper side in the inclined direction are opened in the vertical direction. By fitting a concave portion having a shape and a corresponding convex portion, the upper and lower surfaces can be aligned and connected.
Therefore, it is possible to prevent the vertical displacement and to make the connecting portion between the shelf members smooth without a step. In addition, even if there is a slight dimensional variation in component manufacturing in a configuration having several sub-tiers of shelf members, the uneven portions can be individually fitted to each tier, which causes variations in dimensions. The unevenness in the tilting direction can be absorbed independently for each stage, and the use of each stage can be performed without trouble.

According to the fourth aspect of the present invention, the upper end edge in the tilt direction of the shelf member element located on the lower side and the lower end edge in the tilt direction of the shelf member element located on the upper side are both side edges orthogonal to the tilt direction. It is possible to connect the side edges, which are orthogonal to the tilt direction, through the guide pieces that expand outward at a constant angle. Therefore, it is possible to prevent the lateral displacement and to connect the shelf members to each other smoothly and continuously even in a plan view, and to perform the stable operation without rattling.
