[0006]
Means for Solving the Invention
The present inventors have conducted intensive research on loading means for storing, dispensing, transporting, and handling ammunition in order to solve the above-mentioned problems, and as a result, by examining the shape and material of a pallet for an ammunition case, the object has been achieved. It has been found that this is achieved and the present invention has been made.
[0007]
That is, the present invention has the following aspects.
(1) A pallet on which a plurality of ammunition cases are stacked. The pallet on which a plurality of ammunition cases are mounted can be stacked via an ammunition case. A pallet for an ammunition case, comprising:
(2) The depth of the ammunition case groove has grooves of the same depth on the back and the front, respectively, and the arrangement of the grooves is the same shape on the back and the front, or the grooves are provided alternately, The depth of the groove is less than half of the maximum outer diameter of the ammunition case, and 1/15 or more of the maximum outer diameter. The thickness dimension of the pallet is less than twice the maximum outer diameter of the ammunition case, and is larger than the depth of the groove. The pallet for an ammunition case according to (1), wherein the pallet is thick.
(3) The pallet for an ammunition case according to (1) or (2), wherein the pallet is made of a material having a specific gravity in a range of 0.50 to 3.00.
(4) The pallet for an ammunition case according to any one of the above (1) to (3), wherein the pallet has a flat surface on a part of the front and back sides.
[0008]
Embodiments of the present invention will be described in more detail.
The material of the pallet for the ammunition case of the present invention is preferably a material having a specific gravity of 0.50 to 3.00 because the pallet is placed in a storage or the like, a plurality of ammunition is placed, and the pallet is handled by a human hand. More preferably, a material containing a conductive or antistatic material and having excellent durability is preferable. When the specific gravity of the material of the pallet is less than 0.50, it is difficult to mount a plurality of ammunition cases because of lack of durability, and when the specific gravity is more than 3.00, the weight of the pallet body increases, which is preferable. Absent. Specific examples of pallet materials include resin materials such as polypropylene, aluminum, wood, and fiber. Preferably, it is better to be made of resin which is easy to mold. More preferably, it is better to be conductive.
[0009]
The shape of the ammunition case groove provided on the pallet is adapted to the shape of the ammunition case, and a plurality of grooves are provided for mounting a plurality of cases. In order to efficiently store the grooves, it is preferable that the grooves are arranged at a position where there is no gap when a plurality of ammunition cases are placed on the pallet. It is preferable that the back and front of the pallet have the same shape or that the back and front grooves are provided alternately. The fact that the back and front of the pallet have the same shape means that when the pallet in the state of FIG. 2 is turned over around the line A, the shape becomes the same before and after returning. The fact that the grooves are alternately arranged on the back and the front means that the arrangement of the grooves is alternately arranged on the back and the front when the pallet is viewed as shown in FIG. The projecting portion of the ammunition case refers to the circular portion itself when it is cylindrical, and the cylindrical shape is the most common shape of the projecting portion of the ammunition case. The depth of the groove for the ammunition case is preferably not more than half of the maximum outer diameter of the ammunition case and not less than 1/15 of the maximum outer diameter. The depth of the groove for the ammunition case shown in FIG. 1 is not more than half of the maximum outer diameter of the ammunition case and is not less than 1/15 of the maximum outer diameter. The maximum outer diameter of the ammunition case refers to the dimension of B in FIG. However, the maximum outer diameter in the case of the ammunition case having the reinforcing ring 9 in FIG. 6 refers to a portion excluding the reinforcing ring. If the depth of the groove for the ammunition case is more than half of the maximum outer diameter, when multiple pallets carrying the ammunition case are stacked, a gap may be created between the ammunition case and the pallet, which may result in poor stability. If the diameter is smaller than 1/15 of the maximum outer diameter, the ammunition case may become unstable when the ammunition case is placed on a pallet due to the shallow groove. In addition, when placing an ammunition case having a reinforcing ring on a pallet, it is necessary to provide a groove for a reinforcing ring indicated by reference numeral 4 in FIG. 2, and the groove is such that the reinforcing rings contact each other when the pallet is stacked. However, it is desirable because it takes up less space for storage. For this reason, the groove for the reinforcing ring may penetrate.
[0010]
Further, the length of the pallet for the ammunition case shown in FIG. Longer lengths can take up space for storage and transportation. It is preferable that the width of the pallet for an ammunition case shown in FIG. 2 be made as close as possible to a size obtained by adding the maximum outer diameter of the ammunition case to the number of pallets. In addition, when storing an ammunition case using an ammunition pallet as shown in FIGS. 4 and 5, a bottom pallet having a structure that can be transported by a forklift or the like as shown by reference numeral 6 in FIG. 4 is separately prepared. It is preferable to load the ammunition case. Fixing with a belt or the like is a more preferable method. As shown in FIG. 1, the thickness of the pallet is desirably not more than twice the maximum outer diameter of the ammunition case and is larger than the depth dimension of the groove for the ammunition case. However, in the case of an ammunition case having a reinforcing ring, the maximum outer diameter means a portion excluding the reinforcing ring. If the thickness of the pallet is larger than twice the maximum outer diameter of the ammunition case, the weight of the pallet increases, and when stacking using the pallet, it becomes impossible to stack efficiently, and the depth of the groove for the ammunition case If the thickness is smaller than the dimension, there is a possibility that the depth of the groove necessary for stably mounting the ammunition case cannot be obtained.
[0011]
When a roller conveyor or the like is used for taking in and out of a storage or the like, it is preferable that a contact surface with the conveyor is flat in order to stably transport a pallet on which a plurality of ammunition cases are placed. The depth to the flat surface shown in FIG. 3 is preferably shallow to ensure the strength of the pallet body. Therefore, the depth is preferably the same as the depth of the groove. Also, the width must be equal to or greater than the width of the conveyor or the like to be used.
As the method of molding the pallet, any method may be used, but for example, in the case of resin, fiber, aluminum, it is desirable to mold by integral molding using a mold in consideration of strength and weight reduction. .
