Description

Technical Field

[0002] The present invention relates to a magazine automatic loading device, specifically to a device capable of automatically completing the receiving, storing, separating, diverting, and loading of projectile particles, belonging to the technical field of automation equipment, and is particularly applicable to fields such as military equipment, industrial automation production lines, and civilian equipment. Background Art

[0004] In current military training, the ammunition control during live ammunition shooting has always been an important part of military management. Moreover, with the deepening of modern live ammunition training, the demand for automated loading control equipment such as automatic ammunition feeding, quantity counting, and magazine automatic loading in the ammunition control process has gradually emerged. Specifically, it is manifested as the automation of comprehensive management such as receiving ammunition, disassembling and assembling ammunition, distributing ammunition, using ammunition, and recycling ammunition. During live ammunition training, training personnel will each receive the corresponding number of bullets, and then they need to load the bullets into the magazine by themselves. When loading the last bullet, it is quite laborious. And when the magazine needs to be replaced during training, the loading of the magazine is a time-consuming and laborious operation. Currently, the actual loading of magazines is still through pure manual operation, and the purpose of designing the magazine automatic loading device is to achieve the automation of receiving ammunition, disassembling and assembling ammunition, and distributing ammunition, reduce the training intensity of training personnel, and improve the training efficiency at the same time. And before the design of magazine automatic loading, some people designed equipment to assist in loading bullets into the magazine in order to reduce the training intensity of training personnel, and it has been widely used in subsequent training. Later, many experts or enterprises have studied or applied the automatic loading system of magazines. Due to the particularity of bullets, clamping by electrical equipment will bring potential safety hazards, and the power demand cannot be met in the wild. The automatic bullet loading system based on friction transmission and spiral transmission enables the entire process of bullet loading into the magazine from disorder to be completed automatically, eliminating the manual sorting link and improving the loading efficiency. However, its mechanical structure is complex, the system volume is large; there are multiple power links, resulting in low clamping reliability, easy damage to the equipment, inconvenient operation, etc. The present invention aims to solve at least one of the technical problems in the related technologies to some extent. For this reason, the main object of the present invention is to provide a convenient mechanical magazine automatic loading system to solve the problems in the prior art such as potential safety hazards caused by clamping with electrical equipment, inability to meet power demand in the wild, complex mechanical structure, large system volume, low clamping reliability caused by multiple moving links, easy damage to the equipment, and inconvenient operation. Summary of the Invention

[0006] Known magazine automatic loading devices typically have exposed operating devices, and there is room for improvement in effectively housing the operating mechanism in a compact housing, improving such operating mechanisms, and improving ergonomics in operation. The following U.S. patents and publications disclose electronic magazine automatic loading devices: 4949495; 9612070; 9719741 and 2016 / 0305727. These references are incorporated by reference for all purposes.

[0007] A motorized magazine automatic loading device for loading ammunition into a magazine includes a housing (1), a projectile particle receiver (2), a storage separation mechanism (3), a diverting mechanism (4), and a loading mechanism (5). A rotary lifting blade (304) is rotatable about a rotational axis inclined at an angle of 7.125 degrees to the horizontal. The loading mechanism (5) includes a magazine receiver for the magazine to be loaded and an eccentric guide rod mechanism for pressing the ammunition into the magazine. All are supported by the housing (1) and substantially housed therein. The optimal ergonomic arrangement of the components and the housing construction provides a minimum footprint, reduced volume dimensions, easily accessible controls for the user, easy ammunition loading, easy insertion and removal of the magazine, high stability, and easy transport. The control circuit (109) includes jamming adjustment means.

[0008] The opening thickness of the chute is generally slightly larger than the maximum diameter of the ammunition. The upper part of the chute has opposing restricting structures that narrow the thickness of the chute on each side of the chute but not in the middle of the upper part. The restricting structures are sized such that the front end of the ammunition is allowed to fall downward due to the reduced diameter at the front end, but the rear end of the ammunition is prevented from passing through the restricting structure due to the increased diameter at the rear end. As the front end falls, the ammunition rotates such that the rear end is upward from the front end, and the rear end becomes more centered in the upper part without the restricting structure, thereby allowing the ammunition to first drop the front end, i.e., the tip. Then, the shape of the chute narrows and sweeps horizontally, forcing each ammunition to rotate as they travel downward along the chute to a horizontal orientation, and then they drop downward into a stack in the accumulator section. The accumulator has a singulation outlet slot located below the stack. A series of individual ammunitions are fed one by one through the singulation outlet slot and into the ammunition receiving area of the loading mechanism (5).

[0009] The main body of the loading mechanism (5) is an eccentric cam guide rod mechanism with reciprocating motion. It includes a motor having a drive shaft and an eccentric cam guide rod member fixed to the drive shaft. The eccentric cam guide rod member is received in an eccentric cam guide rod follower cavity defined by a pusher of the pusher mechanism. The eccentric cam member is eccentrically shaped such that rotation of the drive shaft causes the pusher to oscillate in a first direction away from the magazine and a second direction toward the magazine as the eccentric cam member rotates in the eccentric cam follower cavity. As the pusher oscillates, the guide rod in the eccentric cam guide rod mechanism pushes a series of individual ammunitions one by one from the lowest ammunition receiving area in a horizontal direction transverse to the stack into the magazine fixed in the magazine receiver. When the guide rod retracts, the magazine holds the ammunitions, and when the plunger retracts through the stack, the next cartridge in the stack falls to the lowest ammunition receiving area.

[0010] Features and advantages of the embodiment are a device that monitors the current drawn by one or more motors of a loading device, such as a stepper motor for separating lifting blades or a general motor for a pushing mechanism. If the current drawn by a motor is greater than a preselected threshold (such as caused by jamming), then the current flowing to the motor is cut off, or the motor is reversed for a few seconds, such as three seconds. If the separating lifting blades cannot rotate properly, the separating lifting blades can be reversed again. After a predetermined number of reversals, the system will malfunction and the motor may be disconnected. The device can prevent damage to the loading device, for example, in case of jamming.

[0011] Features and advantages of the embodiment are a motorized magazine automatic loading device having a housing that houses all power mechanisms, excluding contact of the user or bystander with the mechanism, the housing effectively supports the mechanism and provides a chassis for supporting the mechanism, and the housing provides the uppermost user interface.

[0012] Features and advantages of the embodiment are an intuitive and easy-to-operate motorized magazine automatic loading device. The folding chute opens on one side of the device to receive ammunitions, the magazine receiver is located on the rear wall of the device and has a blocking cover plate for fixing the magazine therein. And the control panel and display are on the tilted front side at the top of the loader, tilted and facing the operator.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings, but it is not intended to limit the present invention.

[0027] Reference Figure 1 and Figure 5 shows a magazine automatic loading device for loading ammunition into a magazine. The loader generally includes a housing (1), a collapsible chute (201), a storage cylinder (301), a bullet separating partition (302), a rotating lifting blade (304), a control circuit (109) including a user interface, a slideway (404), and a loading mechanism (5) including an eccentric cam guide rod mechanism and a magazine receiver.

[0028] Reference Figure 1 In the housing (1) of the magazine automatic loading device, there are a housing body (101), a housing top cover (102), a housing inclined surface (103), a housing front side surface (105), and a housing bottom plate (106), and the housing defines the interior of the housing.

[0029] Referring to Figure 5 the rotating lifting blade (304) is used to sequentially receive and lift in a continuous flow batches of disordered ammunition placed at the inner bottom of the storage cylinder.

[0030] Referring to Figure 5 the rotating lifting blade (304) operates as follows. Batches of disordered ammunition are placed in the storage cylinder. The lower half of the storage cylinder is internally connected to and supports the rotating lifting blade (304), which can rotate around a rotation axis inclined at an angle of 7.125 with the horizontal, and can lift the ammunition to the outlet slot (311). In an embodiment, after the batches of disordered ammunition enter the interior of the storage cylinder (301), the rotating lifting blade (304) sequentially lifts the ammunition. However, there is no orientation with respect to the two ways of pointing to the front end and the rear end. Each ammunition is lifted to the bottom outlet slot (311) of the raised cylinder in or supported by the housing. In an embodiment, the outlet slot (311) is defined by an opening in the storage cylinder (301). When each ammunition aligns with the outlet slot (311), the ammunition rolls or drops out and enters the slideway (404).

[0031] Referring to Figure 4, in an embodiment, a series of individual ammunitions are fed one by one through an outlet slot (311) at the bottom of a storage cylinder and into a loading mechanism (5). In an embodiment, the loading mechanism (5) includes a common DC motor (501) that provides power. An eccentric member is received in an eccentric follower defined by the common DC motor (501) of the loading mechanism (5). The shape of the eccentric member is such that when the drive shaft connection disk of the eccentric wheel member rotates, the guide rod (504) oscillates in a first direction and a second direction towards the magazine interface (505) of the magazine interface (505). When the guide rod (504) oscillates, a series of individual ammunitions are fed one by one through a single outlet slot (311). The guide rod (504) of the eccentric loading mechanism pushes a series of individual ammunitions one by one into the captured magazine in a direction transverse to the stack, and the ammunitions are accommodated therein.

[0032] Referring to Figure 4 , in an embodiment, the loading eccentric mechanism of the magazine automatic loading device further includes a chute photoelectric sensor (401) for detecting the progress of loading completion. In an embodiment, the chute photoelectric sensor (401) is positioned by the magazine interface (505).

[0033] Referring to Figure 3 , the magazine automatic loading device further includes a chute state detector chute detection piezoelectric sheet (203) for determining whether there are bullets remaining at the foldable chute (201). In an embodiment, the foldable chute (201) is connected to the foldable chute support (202) through an opening slot inside the foldable chute support, so that the foldable chute (201) has two different states in idle and working, and it extends into the storage cylinder (301). In an embodiment, the chute state detector is supported by the foldable chute support (202). In an embodiment, the chute state detector is a chute detection piezoelectric sheet (203) of 140mm * 12mm. In an embodiment, when the foldable chute (201) is in the working state and has bullets, the chute detection piezoelectric sheet (203) in the chute will generate a piezoelectric effect to generate an electrical signal, and the state of the chute is determined by feeding back the generated electrical signal through the piezoelectric sheet.

[0034] Referring to Figure 5, the magazine automatic loading device may further include a photoelectric sensor (310) at the bottom of the storage cylinder (301). In an embodiment, the photoelectric sensor (310) at the bottom of the storage cylinder provides a signal from which the approximate number of bullets in the bottom of the storage cylinder can be inferred. In an embodiment, when there are sufficient bullets at the bottom of the storage cylinder, the detected photoelectric sensor (310) provides a signal in response to the light reflected by the indicator. The reception of the signal can be timed by a processor in the control circuit (109), so as to provide a basis for the working state of the long-stroke electromagnet (303). In an embodiment, the photoelectric sensor (310) at the bottom of the storage cylinder (301) can be supported by the barrel of the storage cylinder (301), such as the photoelectric sensor support (309) on the barrel.

[0035] Refer to Figure 4 and 7 , in an embodiment, the loading eccentric wheel mechanism of the loading mechanism (5) may further include an ammunition detector for detecting the presence of ammunition in the ammunition receiving area, which is the lowest ammunition position. In an embodiment, the ammunition detector is operably coupled to the control circuit (109), and the control circuit (109) includes one or more processors and a non-transitory computer-readable medium storing one or more instruction sets. The one or more instruction sets include instructions configured to be executed by the one or more processors, so that the control circuit (109) determines the presence of ammunition in the ammunition receiving area based on the signal from the ammunition detector. The lack of ammunition may prevent the operation of the pusher mechanism.

[0036] Refer to Figure 3 , in an embodiment, the magazine automatic loading device includes a foldable chute detector photoelectric sensor (204) for determining whether there is ammunition in the chute. In an embodiment, the foldable chute detector is operably coupled to the control circuit (109), and the control circuit (109) includes one or more processors and a non-transitory computer-readable medium storing one or more instruction sets. The one or more instruction sets include instructions configured to be executed by the one or more processors, so that the control circuit (109) determines whether there is ammunition in the foldable chute (201) based on the signal from the photoelectric sensor (204), in order to better control the operation of the anti-jamming roller (206).

[0037] Refer to Figure 4 and 6, in an embodiment, the loading eccentric wheel mechanism of the magazine automatic loading device further includes a magazine interface (505), a magazine fixing piece (506); and a right-angle photoelectric sensor (406) for detecting the presence of a magazine in the magazine interface (505). In an embodiment, the right-angle photoelectric sensor (406) is supported by a right-angle photoelectric sensor support (407). In an embodiment, the magazine detector includes a magazine detection piezoelectric piece (405) that operates based on the piezoelectric effect. In an embodiment, the magazine detection piezoelectric piece (405) is placed in the receiving cavity of the magazine interface (505). In an embodiment, when the magazine is connected to the magazine interface (505), the magazine detection piezoelectric piece (405) provides a piezoelectric signal generated in response to the action of the magazine.

[0038] Refer to Figure 5 , the magazine automatic loading device may further include a working state detector for detecting the working state of the long-stroke electromagnet (303) in the closed position of the long-stroke electromagnet. In an embodiment, the long-stroke electromagnet (303) is fixed inside the storage cylinder (301) by bolts. In an embodiment, when the photoelectric sensor (310) provides a signal in response to the light reflected from the ammunition at the bottom of the cylinder, the long-stroke electromagnet (303) is in its closed state. Conversely, when the number of bullets at the bottom of the storage cylinder (301) is insufficient, the photoelectric sensor (310) does not receive the signal of the light reflected from the ammunition at the bottom of the cylinder, thereby causing the long-stroke electromagnet (303) to start changing from the closed state to the working state.
