Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a device for loading a plurality of bullets into a model gun magazine.

Model gun magazines can be loaded with multiple bullets. The bullets loaded in the magazine are elastically pushed out by a spring. In order to push out the bullets one by one with a spring, the magazines are lined up in a row and stored. Magazines of this structure require the bullets to be forced in. This is because it is necessary to compress the spring of the magazine when pushing the bullet. Therefore, there is a drawback that it takes a lot of time to load the bullet. To load the magazine into the magazine without using the bullet loader, it is necessary to push the bullets one by one to compress the spring. This method has the drawback that loading is extremely time-consuming. To overcome this drawback, ammunition loading devices have been developed. The bullet loading device currently in use has a mechanism in which a push-rod is inserted through a cylindrical casing. This bullet loading device is used in the following conditions. Insert the bullet into the casing while pulling the push rod. In this state, the casing is loaded with a plurality of bullets arranged in a line. In order to push the bullets from the casing into the magazine, the open end of the casing of the bullet loading device is brought into contact with the bullet filling hole of the magazine. In this state, the push rod is pushed into the cylindrical casing to forcibly push out the internal bullet and push it into the magazine.

[Problems to be solved by the device]

The bullet loading device of this structure has a feature that it can be loaded faster than loading the bullets one by one by hand. However, the bullet loading device having this structure has a drawback that it takes a lot of time to insert a bullet into the tubular casing. As described above, since it takes time and effort to load the magazines, a plurality of magazines are used together with the model gun. That is, when loading a bullet, a plurality of magazines are loaded together, and when a model gun is used, another magazine is loaded into the model gun and used each time a bullet in the magazine is fired. You don't have to use multiple magazines for a single model gun if you can load magazines easily and quickly. This is because each time a bullet is fired from the magazine, it can be loaded in a short time. The present inventor has developed a device for loading bullets in a magazine by arranging bullets in a row with a motor, in order to solve this drawback. This device has the feature that it can be loaded into a magazine very easily. However, there is a drawback that after the loading of the magazine is completed, an unreasonable force is applied to the drive unit for loading the bullet, which may cause a failure, or the bullet may leak out from the connecting portion between the magazine and the bullet loading device. It was The reason is that the motor is not stopped after the magazine has been loaded. After the bullet has been loaded into the magazine, if the motor rotates to force the bullet into the magazine, the bullet cannot be pushed out, so a strong force acts on the gears and parts that push out the bullet, causing damage to them. Becomes In particular, the mechanism in which a large number of bullets are arranged in a row and pushed into the magazine cannot be smoothly loaded into the magazine unless it is pushed out with a considerably strong force. Therefore, a strong torque is required for the motor. A large-torque motor has a characteristic that when it is stopped, a stronger rotating torque becomes stronger. This is because a brushed DC motor is used for this type of application. The DC motor has a torque curve in which the torque increases as the rotation speed decreases. This characteristic has the effect of smoothly pushing out bullets in normal use. This is because when the bullets become clogged and are difficult to push out, the torque of the motor increases and the bullets are pushed out with a stronger force. However, after the bullet has been loaded into the magazine, the stronger the motor pushes the bullet, the more unreasonable force acts on the drive mechanism that pushes out the bullet. For this reason, there is a drawback that the drive mechanism is damaged and is likely to fail. If the bullet loading device is removed from the magazine so that the drive mechanism is not overloaded, bullets will leak to the outside one after another from between the bullet loading device and the magazine. The bullet loading device of the model gun of the present invention was developed to further solve this drawback, and the important purpose of the present invention is to stop the rotation of the motor when the magazine is loaded, It is an object of the present invention to provide a bullet loading device for a model gun in which an excessive force does not act on a mechanism for loading a bullet and a bullet does not leak outside.

(G) The magazine contact portion of the movable piece 11A is arranged so as to be movable in the axial direction of the extrusion path 6. (H) When the magazine has been loaded and the casing is pressed by the magazine and separated from Tsugajin, the movable piece 11A that comes into contact with the magazine moves and the limit switch 11 is turned off to stop the power supply to the motor 3. Is configured.

[Operation effect]

The state in which the bullet loading device of the model gun of the present invention supplies bullets to the magazine will be described with reference to FIG. 1 showing a preferred embodiment of the present invention. The bullet loading device shown in the figure loads bullets into the magazine in the following states. The storage chamber 4 of the casing 1 is filled with a large number of bullets. It is not necessary to insert the bullets placed here side by side, nor to push them in. It can be inserted by opening and closing the opening / closing lid 8. The tip of the extrusion path 6 is connected to the bullet feed hole of the magazine M so that the bullet can be pushed into the magazine M from the bullet loading device, and the bullet loading device is pressed against the magazine M. When the bullet loading device approaches the magazine M, the movable piece 11A of the limit switch 11 is pushed to be turned on. The motor 3 rotates to drive the forced extrusion member 2. The forced pushing member pushes the bullets in a line and pushes them out from the pushing path 6. The bullets pushed out from the tip of the extrusion path 6 are the magazines M
Are supplied side by side. When the loading of the magazine M is completed, the bullet cannot be pushed out of the extrusion path 6. With the bullet unable to be pushed out,
When the forced pushing member further pushes out the bullet, the casing of the bullet loading device is pushed in the direction away from the magazine M by the reaction of pushing the bullet. When the magazine loading device is pushed in the direction in which the magazine M moves away, the movable piece of the limit switch 11 that contacts the magazine M
11A moves. When the movable piece 11A moves, this moves the limit switch 11 from the ON state to the OFF state. The rotation of the motor 3 is stopped and the bullet loading is stopped. In this state, the bullet loading device that can feed bullets to the magazine,
The tip of the extrusion path can be applied to the bullet feed hole of the magazine M, and the motor can be rotated to load the magazine. For this reason, the bullet loading device of the present invention has a feature that it can be easily and easily loaded in a magazine in a short time. Furthermore, in the bullet loading device of the model gun of the present invention, the motor automatically stops when the magazine has been loaded. Therefore, after the bullet is loaded, a strong force does not act on the mechanism for pushing the bullet, and the failure of the drive mechanism for pushing the bullet can be minimized. Furthermore, since the bullet loading device of the present invention does not need to remove the bullet loading device from the magazine even after the loading of the magazine is completed, it is possible to prevent bullets from leaking to the outside from the magazine of the magazine and the bullet loading device. . Therefore, the model gun bullet loading device of the present invention has a feature that it can be easily and conveniently used and can be loaded in a magazine in a short time.

[Preferred embodiment]

An embodiment of the present invention will be described below with reference to the drawings. However, the embodiments described below exemplify a bullet loading device of a model gun for embodying the technical idea of the present invention, and the bullet loading device of the present invention is composed of materials, shapes, structures of components, The arrangement is not specific to the structure below. The ammunition loading device of the present invention is subject to various modifications within the scope of the claims for utility model registration. Further, in this specification, in order to facilitate understanding of the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiment are
It is added to the members shown in "Column for request for utility model registration", "Column for means for solving conventional problems", and "Column for action and effect". However, the members shown in the scope of claims for utility model registration are by no means limited to the members of the embodiment. The model gun bullet loading device shown in FIGS. 1 to 3 includes a casing 1, a forced pushing member 2, and a motor 3. However, FIG. 3 shows the main part of the apparatus shown in FIG. The casing 1 is entirely made of synthetic resin. The casing 1 is formed by fixing two separately molded case pieces to each other and fixing them therein, and a rotation path 5 in which a storage chamber 4 for storing a large number of bullets and a forced extrusion member 2 are rotatably arranged. And an extrusion path 6 for arranging and sending bullets. The storage chamber 4 has a volume capable of storing a large number of bullets, for example, several tens to several hundreds of bullets. As shown in the sectional view of FIG. 2, the width d of the lower portion of the storage chamber 4 is adjusted to be slightly larger than the diameter of the bullet and smaller than twice the diameter of the bullet. This is because the bullets are stored in a single plane as shown in the sectional view of FIG. The bullets stored in a single plane have the advantage that they can be smoothly fed to the rotating path without forming a bridge. As shown in FIG. 1, an opening / closing lid 8 for supplying bullets is provided at the opening of the storage chamber 4. The bullets stored in the storage chamber 4 are lined up one row and sent to the rotary path 5. Therefore, as shown in FIG. 1, the bottom of the storage chamber 4 is formed in a downward tapered shape. The rotating path 5 is provided so as to be connected to the bottom of the storage chamber 4. The rotating path 5 arranges the bullets in one line by the rotating forced pushing member 2 and transfers the bullets to the pushing path 6. In order to transfer the bullets arranged in a line by the forced pushing member 2 rotating in the rotating path, the rotating path 5
Has an arc shape. The width of the rotary path 5 is equal to the width of the storage chamber 4, and the inner diameter is adjusted to a length that allows bullets to be transferred between the teeth of the forced extrusion member 2. The rotating path 5 pushes the bullet taken in from the storage chamber 4 to the extrusion path 6 without returning it to the storage chamber 4. In other words,
A partition wall 7 is provided in a part of the arc-shaped rotation path 5 to partition the extrusion path 6 and the storage chamber 4. The partition wall 7 is provided in the rotating path 5 at the boundary with the extrusion path 6. In the portion of the rotary path where the partition wall 7 is provided, the forced extruding member 2 can rotate so that the bullet cannot pass therethrough, but the width that the bullet cannot pass, that is, the thickness of the forced extruding member 2 is 0.1 to several mm. Wide and narrower than the diameter of the bullet. The extrusion path 6 is supplied with bullets from the rotation path 5. Therefore, the extrusion path 6 is connected to the discharge side of the rotary path 5 and is connected to the storage chamber 4 via the rotary path 5. The push-out path 6 has such a thickness that the bullets can be lined up and transferred so that the bullets can be fed to the magazine M one by one, in other words,
It is made 0.2 to a few mm larger than the outer diameter of the bullet. A nozzle capable of smoothly pushing the bullet into the magazine M is provided at the tip of the extrusion path 6. The forced pushing member 2 rotates in the rotation path 5 to transfer the bullets arranged side by side on the outer circumference. Therefore, the forced extrusion member 2 is formed in a gear shape having teeth on the outer circumference. The teeth of the forced extruding member 2 are adjusted to have an interval such that a bullet can be inserted and transferred. The distance between the teeth is 0.2 to a few meters, for example 0.2 to a few m
m big. The forced pushing member 2 is rotated by a motor 3 via a reduction gear (not shown). Therefore, the rotating shaft 9 is fixed to the center of the forced pushing member 2, and the rotating shaft 9 is connected to the output shaft of the motor 3. The motor 3 rotates the forced extrusion member 2 in the direction indicated by the arrow in the figure. The forced pushing member 2 rotated in this direction sends the bullet in the storage chamber 4 from the rotation path to the pushing path 6. The forcible pushing member 2 arranges the bullets one by one and forcibly pushes them one after another. When the magazine M is loaded with bullets, the extrusion path 6
Bullets are no longer pushed out from. In this state, the forced extrusion member 2 cannot rotate. By utilizing this, the motor 3 can be automatically stopped when the magazine M is completely loaded with bullets. To realize this, the limit switch 11 is fixed to the casing. The limit switch 11 is fixed near the extrusion path 6. The limit switch 11 includes a movable piece 11A that switches between on and off states. When the movable piece 11A is pushed in,
The limit switch 11 is turned on and turned off when the movable piece 11A is pushed out. The movable piece 11A of the limit switch 11 contacts the bullet loading device. When the movable piece 11A is moved by the magazine M, the limit switch 11 detects the distance between the magazine M and the bullet loading device. Once the magazine M has been loaded,
When the distance between the bullet loading device and the magazine M becomes wider, the limit switch 11 is switched from the on state to the off state. Therefore, the limit switch 11 allows the movable piece 11A to move in the direction in which the bullet is pushed out of the extrusion path 6.
It is fixed to the casing. The bullet loading device of FIG.
The magazine is loaded by pushing the bullet upward. Therefore, the limit switch 11 is fixed to the casing so that the movable piece 11A can move up and down. Further, the movable piece 11A is pushed in a posture in which the bullet loading device is pressed against the magazine M to load the bullets, the limit switch 11 is turned on, the loading is completed, and the space between the magazine M and the bullet loading device is completed. When it becomes wider, it is pushed out of the limit switch 11 and switched to the off state. Therefore, the movable piece 11A is adjusted to have a length in which the movable piece 11A is brought into contact with and pushed in the magazine M in a state in which the extrusion path 6 is set in the magazine M. The movable piece 11A of the limit switch 11 shown in FIG. 1 is composed of one rod. However, the movable piece of this invention is not specific to this structure. Although not shown, it is needless to say that a link mechanism that connects a plurality of rods can be used as the movable piece. Further, in the bullet loading device of FIG. 1, the movable piece is brought into direct contact with the magazine M, but the movable piece does not necessarily have to come into direct contact with the magazine M. For example, it is also possible to contact the magazine M via a flexible sheet or the like. The movable piece 11A of the limit switch 11 shown in FIG. 1 is elastically pushed out by a spring (not shown). Therefore, the movable piece 11A is turned on only when the movable piece 11A is pushed. 1 to 3, the forced pushing member is formed in a gear shape. However, this device does not specify the forced extrusion member to the mechanism shown in the above figures. As the forced pushing member, it is possible to use a mechanism having all the mechanisms capable of arranging and pushing the bullets from the storage chamber 4 to the pushing path 6 in a line. The forced extrusion member 2 shown in FIGS. 4 and 5 is composed of an extrusion cylinder 2A driven by a cylinder 2C and a stopper 2B. In this forced extrusion member 2, an extrusion cylinder 2A and a stopper 2B are reciprocated by a cylinder 2C in synchronization with each other. The extruding cylinder 2A has a cylindrical shape with an opening at the upper end and the left side in the drawing. Stop
2B is arranged in the middle of the extrusion path 6 and is arranged so that it can freely move in and out of the extrusion path 6. The forced pushing member pushes the bullet through the pushing path 6 in the following state. As shown in FIG. 4, when the push-out cylinder 2A descends, bullets flow from the storage chamber 4 into the push-out cylinder 2A. At this time, the stopper 2B is pushed into the extrusion passage 6 to prevent the backward flow of the bullets in the extrusion passage 6. As shown in FIG. 5, the push-out cylinder 2A moves up to push the bullet out of the push-out path 6. At this time, the stopper 2B is pulled out of the extrusion passage 6 so that the bullet can freely pass through the extrusion passage 6. Further, when the push-out cylinder 2A rises, the push-out cylinder 2A closes the passage with the storage chamber 4. After the push-out cylinder 2A has moved to the upper end, the stopper 2B is inserted into the push-out path 6 as shown by the chain line in FIG. With the stopper 2B stopping the backward flow of the bullet, the push-out cylinder 2A descends and fills the bullet there. The forced extruding member of this structure repeats this operation to arrange the bullets in the storage chamber 4 in one line and push them out from the extruding path 6.
