Japanese Utility Model Laid-Open No. 6-32328

By the way, in the container described in Patent Document 1, the lower surface side of the leg portion is rib-shaped, and the contact area is relatively small. For this reason, for example, when the container of Patent Document 1 is conveyed by a chain conveyor or a roller conveyor, the lower surface of the legs and the conveyor are not properly engaged, which may cause problems such as idle rotation of the conveyor. In addition, there is concern that the lower surface side of the leg may be easily worn. Furthermore, since the area of the lower surface of the leg is small, there is a high possibility that the wear of the lower surface of the leg will have a relatively large effect on the installation surface such as the floor of the container and the installation state on the conveyor. There is also a concern that the container may rattle when installed, and problems such as idling and bending of the container in the conveying direction may easily occur when the container is conveyed on the conveyer.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems exemplified above, and an object of the present invention is to provide a container having legs, which can improve the efficiency of conveying by a conveyor. be.

Hereinafter, each means suitable for solving the above problems will be described separately. It should be noted that actions and effects specific to the corresponding means will be added as necessary.

Means 1. 1. A container having a substantially rectangular bottom wall-constituting portion in a plan view and side wall portions extending upward from respective side portions of the bottom wall-constituting portion, and capable of accommodating articles in an inner storage space. ,
The bottom wall forming portion includes a bottom wall portion forming a bottom surface of the accommodation space and a leg portion projecting downward from a lower surface of the bottom wall portion,
The leg portion is configured as a leg portion main body integrally formed with the bottom wall portion, and as a separate body from the leg portion main body, and is attached to the leg portion main body so that the container is placed on the installation surface. A grounding member that is grounded on the installation surface when installed,
The leg main body is provided with a mounting portion to which the grounding member is mounted,
The grounding member has an engaging portion that is disposed on the front side in the mounting direction of the grounding member to the mounting portion and faces and abuts or approaches the locked portion provided on the mounting portion. prepared,
When the grounding member is viewed from below, it is provided so as to correspond to an end of the grounding member opposite to the end on which the locking portion is provided, and protrudes from the grounding member so as to extend from the mounting portion. It has a pressing part that is pressed against the inner surface ,
A stacking convex portion projecting upward is provided on the upper surface side of each corner portion where the side wall portions are connected to each other,
The leg main body is
Equipped with four outer wall portions extending in a direction substantially parallel to each side portion of the bottom wall-constituting portion, and having a substantially tubular shape opening downward,
a substantially L-shaped partition wall portion connected at both ends to inner surfaces of two of the four outer wall portions facing the outer peripheral side of the bottom wall portion;
With the partition wall as a boundary, a stacking concave portion is provided on the corner portion side of the bottom wall portion, and the mounting portion is provided on the central portion side of the bottom wall portion,
When the containers are stacked together, the stacking protrusion of the lower container is inserted into the stacking recess of the upper container,
The grounding member has a member grounding surface that is grounded on the installation surface when the container is installed on the installation surface,
A container according to claim 1, wherein the member contact surface is substantially L-shaped along two inner side surfaces of the leg main body when viewed from below.

According to Means 1, by attaching the grounding member to the leg main body, it is possible to ensure a relatively large area of the grounding surface of the leg that is in contact with the installation surface on which the container is installed. As a result, even when the container is conveyed by a chain conveyor or a roller conveyor, the grounding (contact) area with the conveyor is increased, and the grounding surface of the leg and the conveyor can be well engaged. . Therefore, it is possible to avoid situations such as idling of the conveyor, and to improve the efficiency of conveying by the conveyor.

In addition, compared to the case where the entire ground contact surface of the leg has a rib shape, it is possible to make the contact surface less likely to wear, and even if the contact surface (contact member) is partially worn, the contact surface (contact member) At other parts of the belt, it is possible to secure a contact area with the conveyor or the like, and to reduce the influence of wear. As a result, the contact surface wears down, and the contact area with the installation surface such as the floor and the conveyor becomes smaller, and when installed on the installation surface, rattling occurs. It is possible to prevent the occurrence of a situation such as bending of the conveying direction of the sheet.

Furthermore, the lower surface of the leg body to which the grounding member is attached may be rib-shaped. In this case, the mold structure forms the leg body while ensuring the compressive strength of the leg body in the vertical direction. complication can be suppressed. In addition, since the grounding member is a separate member from the leg main body and is a dedicated member for the leg, it is possible to relatively easily increase the accuracy of the shape. Therefore, it is possible to avoid a situation in which the conveying efficiency of the conveyor is lowered due to the distortion of the ground contact surfaces (ground contact members) of the legs. In addition, the grounding member can be relatively easily replaced with a new one according to deterioration or with a different type according to the application. Therefore, it is possible to avoid exchanging the entire container just because a problem occurs on the bottom side of the leg, or preparing multiple types of containers just to change the shape of the bottom side of the leg. , versatility and convenience can be improved, cost can be reduced, space can be saved during storage, and the like. By providing the legs, it becomes possible to lift the container by inserting a fork such as a forklift under the bottom wall portion of the bottom wall forming portion.

In addition, it is possible to prevent the grounding member from falling off from the mounting portion, and to improve mounting workability, etc., compared to the case where the grounding member is mounted to the mounting portion with screws or the like.

Further, the grounding member and the mounting portion are pressed against each other at the pressing portion, so that the grounding member attached to the mounting portion can be prevented from rattling. In particular, since the pressing portion is provided corresponding to the side portion of the grounding member opposite to the side portion side where the locking portion is provided, the locked state of the locking portion with the locked portion Displacement to the side where the contact is released can be prevented, and drop-off of the grounding member from the mounting portion can be more reliably prevented. In addition, compared to the case where the number of locking portions and locked portions is increased in place of the pressing portion, the structure of the grounding member and the mounting portion (molding mold) can be prevented from being complicated, and the grounding can be prevented. The mounting state of the member can be stabilized.

Furthermore , when the container is placed on the conveyor in a direction in which a predetermined side portion of the bottom wall-constituting portion is parallel to the conveying direction of the conveyor, and when the container is placed on the conveyor in the direction of paralleling the predetermined side portion of the bottom wall-constituting portion ( The longitudinal width of a member such as a roller of a roller conveyor that is in direct contact with a workpiece and feeds the workpiece in both cases where the container is placed on the conveyor with the side part extending in the direction parallel to the conveying direction of the conveyor. It is possible to ensure the width of the grounding member (member grounding surface) in the direction crossing the direction. Therefore, depending on the orientation of the container to be placed on the conveyor, the contact between the conveyor and the contact surface of the grounding member may become poor, and the effect of improving the conveying efficiency of the conveyor may not be achieved. can be avoided.

As described in detail above, according to this embodiment, by attaching the grounding member 31 to the lower surface side of the leg body 10a (corner post body 101a), the leg is grounded to the installation surface on which the container 1 is installed. A relatively large area can be secured for the contact surface of the portion 10 (in this example, the lower edge of the leg body 10a and the lower surface of the contact member 31). As a result, even when the container 1 is conveyed by a chain conveyor or a roller conveyor, the grounding (contact) area with the conveyor is increased, and the contact between the grounding surface of the legs 10 and the conveyor is improved. can be done. Therefore, it is possible to avoid situations such as idling of the conveyor, and to improve the efficiency of conveying by the conveyor.

In addition, compared to the case where the entire ground contact surface of the leg portion 10 has a rib shape, the ground contact surface can be made less likely to wear, and even if a part of the ground contact surface (ground contact member 31) is worn, the ground contact surface (ground contact member 31) can be Other portions of the member 31) can ensure a contact area with the conveyor or the like, and can reduce the influence of wear. As a result, the ground contact surface wears out, and the installation surface and the contact area to the conveyor become smaller, causing rattling when installed on the installation surface. It is possible to prevent the occurrence of a situation such as bending.

Further, the lower surface side of the leg body 10a (corner post body 101a) to which the grounding member 31 is attached can be formed in a rib shape, thereby securing the compressive strength of the leg body 10a in the vertical direction while allowing the leg body 10a to move. It is possible to suppress complication of the mold structure to be formed. In addition, since the grounding member 31 is a separate member from the leg main body 10a and is a dedicated member for the leg 10, it is possible to relatively easily increase the accuracy of the shape. Therefore, it is possible to avoid a situation in which the conveying efficiency of the conveyor is lowered due to distortion of the ground contact surface (ground contact member 31) of the leg portion 10 or the like. In addition, the grounding member 31 can be relatively easily replaced with a new one according to deterioration or with a different type according to the application. Therefore, it is not necessary to replace the entire container 1 when a problem occurs on the lower surface side of the leg portion 10, or to prepare a plurality of types of containers 1 simply to change the shape of the lower surface side of the leg portion 10. Therefore, it is possible to improve versatility and convenience, reduce costs, and save space during storage.

Further, the grounding member 31 has a locking portion 35 that is locked to a locked portion 44 provided on the mounting portion 41 . Therefore, it is possible to prevent the grounding member 31 from falling off from the mounting portion 41, and to improve mounting workability, etc., compared to the case where the grounding member 31 is mounted to the mounting portion 41 with screws or the like. . In addition, the grounding member 31 has a pressing portion 36 protruding outward from the outer surface of the positioning piece portion 33 , and the pressing portion 36 is pressed against the inner surface of the mounting portion 41 when the grounding member 31 is attached to the mounting portion 41 . It is designed to be Therefore, the grounding member 31 and the mounting portion 41 are brought into pressure contact with each other at the pressing portion 36, so that the grounding member 31 attached to the mounting portion 41 can be prevented from rattling. In particular, since the pressing portion 36 is provided on the outer surface side of the positioning piece portion 33 facing the positioning piece portion 33 on which the locking portion 35 is provided in the grounding member 31, the locked portion of the locking portion 35 Displacement to the side where the locked state with 44 is released can be prevented, and falling off of the grounding member 31 from the mounting portion 41 can be prevented more reliably. In addition, compared to the case where the numbers of the locking portions 35 and the locked portions 44 are increased instead of the pressing portions 36, the structure of the grounding member 31 and the mounting portion 41 (molding die) is not complicated. It is possible to stabilize the mounting state of the grounding member 31 while restraining it.

In addition, the lower surface of the base plate portion 32 of the grounding member 31 extends along two inner side surfaces of the corner post main body 101a (a side portion extending along the longitudinal width direction of the container 1 and a side portion extending along the lateral width direction of the container 1). It has a substantially L-shape including a side portion extending along the edge. Therefore, when the container 1 is placed on the conveyor with the long side of the bottom wall-constituting portion 5 (bottom wall 9) parallel to the conveying direction of the conveyor, and when the short side of the bottom wall-constituting portion 5 is In both cases where the container 1 is placed on the conveyor in a direction parallel to the conveying direction of the conveyor, the longitudinal width direction of a member such as a roller of a roller conveyor or a chain of a chain conveyor that directly contacts the work to send the work. The width of the grounding member 31 in the direction intersecting with the Therefore, depending on the direction of the container 1 to be placed on the conveyor, the contact between the conveyor and the lower surface of the grounding member 31 may become poor, and the effect of improving the conveying efficiency of the conveyor may not be obtained. can be avoided.
