る。Further, studies have been made to automatically supply a bullet and a propellant charge to a gun by a mechanical device for the purpose of improving the shooting speed of the gun and reducing the number of operating personnel.
As a propellant charge suitable for this purpose, there is a modular propellant charge consisting of a plurality of basic units. Modularized propellant charge is prepared by connecting multiple modules required for shooting at maximum shooting distance in advance, and mechanically separating and loading into the number of modules according to the target shooting distance at the time of shooting. To do. A burn-out container is essential in making this modular propellant charge, and the way in which it can be connected is a problem. Regarding the method of connecting the burnable container, Japanese Patent Laid-Open No. 2-500772 discloses that
As shown in FIG. 7, it is possible to connect the propellant charges 71, 72 modularized by using the plug-type connecting member 73, and in Japanese Patent Laid-Open No. 4-347500, modularization is performed as shown in FIG. The launch charge 81, 82 is connected to the connecting portion 8 respectively.
An invention has been disclosed in which the modules are integrated in the medicine chamber by providing 5,86 to enable simultaneous ignition.

Since kraft pulp and synthetic resin are used as the main raw materials, they are more fragile than metal materials, and their dimensions are easily affected by climate and environmental changes such as humidity, and the manufacturing environment and manufacturing process time are strictly controlled. However, it is very difficult to improve the dimensional accuracy. In the method of connecting a modularized propellant charge by using the above-mentioned plug-type connecting member or by providing a connecting portion at one end of the burnable container, the connecting force of the connecting portion is a ring-shaped female portion and a reduced diameter. Since it is determined by the fit and frictional resistance of the male part, it is impossible to make all modules have a constant binding force.

性容器が破壊するといった問題があった。(Mechanical Device Separation) A method for mechanically separating a modularized propellant charge is performed by pressing the outer periphery of the burnable container so as to be sandwiched by the serrated clamp jaws of the separating device.
A general method is to pull out in the long axis direction. If the coupling force of the modules is not constant, the separating force of the module and the pressing force of the clamp claws must be set so that the module having the highest coupling force can be separated. In this way, when the separation force of the module and the pressing force of the clamp claw are set to a large value, the burnable container becomes deformed and cannot be separated. There was a problem of destruction.

となる問題があった。(Handling by Human Power) When the mechanical device for separating the modules fails, it is necessary to have operability so that the modules can be rearranged manually and supplied to the fire gun. Therefore, when supplying the propellant charge to the gun by human power, even if both ends of the connected module are supported, it is necessary to have a binding force that does not cause the module to separate due to deflection of the center of the propellant charge due to its own weight. . Furthermore, since it is difficult to manually pull out the connected modules in the long-axis direction to separate them, a method of applying a force in the short-axis direction to the modules to be separated and breaking the joint portion is taken. . If the connecting force is such that the both ends of the connected modules are not separated even if they are supported, the connecting part of the burnable container will be deformed or damaged during the above-mentioned manual separation, and it will be difficult to connect again. There was a problem that became.

とである。(Exhaustibility) It is required that an exhaustible container does not generate unburned residue when used in a gun (exhaustible).
With modularized propellant charge, there should be no unburned residue from the number of modules at maximum range to one module. Considering mechanical separation and handling by human power, it is necessary to make the burnable container strong, but when such a strong burnable container is used with a fire gun, especially when used in one module. Had a problem such as an unburned residue. An object of the present invention is to provide a burnable container which can be reliably separated when using a mechanical separating means and which can be easily handled by human power.

の力に対する強度も向上させる。Although the position of the projection 18 on the reduced diameter end portion 15 is not specified, it is practically desirable to provide the central portion of the reduced diameter end portion 15 at a position that divides it into three or four equal parts.
Further, the shape of the protrusion 18 can be any shape such as a circle or a quadrangle. The thicknesses of the burnable case 12 and the burnable cap 13 are usually appropriately determined in consideration of two factors, that is, burnout when the burnable container is used in a fire gun and strength to withstand impact such as dropping, but are preferable. The range is 1/150 to 1/50 of the outer diameter of the cylindrical portion of the burnable case 12.
When the thickness of the burnable case and the burnable cap is less than 1/150 of the outer diameter of the cylindrical portion of the burnable case, the strength of the modular explosive charge is poor even if the dimensional accuracy is increased, On the other hand, when the thickness exceeds 1/50, unburned residue occurs when used in a gun. In FIG. 1, the burnout container 11 is provided with a clamp groove 1 if necessary.
4 can be attached. The clamp groove 14 is not necessarily provided, but when the clamp claw of the separating device is hooked on the clamp groove, the clamp groove 14 is provided along the circumference of the burnable case 12 to provide an effective structure. The clamp groove 14 can be arranged at an arbitrary position on the outer surface of the burnable case 12. However, by providing the clamp groove 14 at a fixed position of the burnable cap 13, the volume and shape of the accommodating portion 17 for propellant etc. can be reduced. There is an advantage that it can be kept constant. or,
The clamp groove 14 does not need to be arranged all around the circumference of the burnable case 12, but it is preferable that the clamp groove 14 be provided all around in order for the clamp claw to be engaged at any position. Further, the shape of the clamp groove 14 can be made to correspond to the shape of the clamp claw, such as a semicircular cross section or a trapezoid.
Further, the clamp groove 14 also improves the strength of the burnable case 12 against a force in the minor axis direction.

合は使用する火砲の要求とする性能から適宜選ばれる。The composition of the burnable container used in the present invention is composed mainly of nitrocellulose, kraft pulp and synthetic resin. The preferred composition of the burnout container for use in field gun propellant charge is 40 to 8 parts by weight nitrocellulose.
It is desirable that the kraft pulp is 0%, the synthetic resin is 5 to 15% by weight, and the other portion is kraft pulp, and further, the weight ratio of nitrocellulose to kraft pulp is desirably 1 to 4. If the ratio of nitrocellulose to kraft pulp is high, the mechanical strength will decrease,
It is necessary to add a large amount of synthetic resin. On the other hand, if the ratio of nitrocellulose to kraft pulp is low, unburned residue will occur when used in a gun, so it is necessary to reduce the amount of synthetic resin. In addition, ethyl centrallite or diphenylamine may be added as a stabilizer for suppressing spontaneous decomposition of nitrocellulose. The blending ratio of these is appropriately selected from the performance required by the fire gun to be used.

From the separation test in the long axis direction, the average value of the separating force was 11 kgf / cm 2 for Comparative Example 1, 13 kgf / cm 2 for Comparative Example 2 , and 46 kgf / c for Example 1.
m 2 , Example 2 was 54 kgf / cm 2 , Example 3 was 30
It was kgf / cm 2 . Examples 1, 2, and 3 are comparative examples 1
Or, it was found to have a separating power of 3 to 5 times that of 2.
The burnout container used was loaded with propellant to give the same weight as the gunpowder charge, and the weight of each module was 2.4 kg. This burnout container is intended to be used by connecting 6 modules. In this case, when 6 modules are placed in a state of being connected in the vertical direction and one module at the upper end is lifted, The weight of the remaining five modules, 12.0 kg, acts on the joint directly below the module. Usually, the propellant charge is often handled in such a manner, but in Comparative Examples 1 and 2, it can be seen that separation occurs even with this handling. On the other hand, in Examples 1, 2, and 3, the level is such that they are not separated by this handling.

Example 2 is 37 kgf / cm 2 , Example 3 is 31 kgf
Was / cm 2 . It was confirmed that when a force in the short axis direction was applied to the burnable containers of Examples 1, 2 and 3, the separation could be performed with a force equal to or less than that in the case of applying a force in the long axis direction. . Furthermore, the separation force when a force in the short axis direction is applied to Examples 1, 2, and 3 is 1.2 to 1.4 times the separation force of Comparative Examples 1 and 2, and the force in the long axis direction is increased. It is smaller than the ratio when added. In Example 2, the separation force was 1.4 times that of Comparative Example 1,
It was the maximum compared with other examples. However, when the present inventors applied a force in the short axis direction for the purpose of splitting the propellant charge coupled by human power, even the module of Example 2 could be separated, and the ring-shaped end No part was damaged.

Since a means to be fitted to the part is provided and connected, a stable and high binding force can be obtained without strictly controlling the wall thickness of the burnable case, thus simplifying the process of manufacturing the burnable container. be able to. Further, since the burnable container of the present invention can obtain a stable and high binding force, there is no fear of non-separation in the separating operation by the mechanical device which has been a concern in the past, and handling such as human transportation and loading. , Can be easily connected and disconnected, and the reliability of the fire system can be increased. Further, the modularized propellant charge using the burnable container of the present invention has different separating force by the mechanical device depending on the size and arrangement of the fitting structure of the joint portion, and therefore, the optimum propellant suitable for the fire system is adopted. be able to. Further, in the conventional burn-out container, it is necessary to make the burn-out container thicker or harder in order to increase the handling ability by human power. In this case, when one modularized propellant charge is used, Although there was a problem of unburned residue, since the burnable container of the present invention has a stable and high binding force, it is possible to use thinner or fragile things than before, and there is no fear of unburned residue. .
