Description

Technical Field

[0001] The invention relates to the technical field of bullet production equipment, and in particular to a bullet weighing device and a bullet weighing classification system. Background Art

[0002] To ensure the accuracy of bullets, during the bullet production process, the weight of individual bullets needs to be weighed and the bullets need to be screened to ensure the overall quality of the bullets.

[0003] The main body of a bullet is generally cylindrical in structure and the head is conical in structure. It is easy to roll when placed flat, making it difficult to accurately weigh it using weighing equipment. In addition, when materials are sent to the weighing equipment through an automatic conveying mechanism, it is easy to convey multiple materials to the weighing pan of the weighing equipment at one time, making it impossible to complete the weighing normally.

[0004] To this end, the Chinese invention patent with patent number CN202221504380.9, named Bullet Weighing and Screening Device, adopts a turntable structure for weighing, a bullet accommodating port is set on the rotating circular plate, and a weighing sensor block is configured, which is automatically fed vertically from the feed pipe to the bullet accommodating port for weighing. Although this method can meet the needs of individual weighing of bullets, it is very easy for the head of the bullet to fall downward into the bullet accommodating port (the bullet is fed in upside down), resulting in failure to weigh. Usually, special personnel are required to correct it. In addition, a primer is provided at the bottom of the bullet. When the bottom of the bullet falls into the bullet accommodating port, it is also dangerous. When the bullet is arranged in the feed pipe, the head of the bullet will also be against the bottom of the bullet, which is also dangerous.

[0046] Reference below Figures 1 to 11 A bullet weighing device and a bullet weighing classification system according to an embodiment of the present invention are described.

[0047] like Figure 7 , Fig.10As shown, the bullet weighing device according to the embodiment of the present invention includes a sorting device 200 and a weighing mechanism 300, the sorting device 200 includes a sorting rotation driving unit 210 and a sorting roller 220 that can be driven to rotate by the sorting rotation driving unit 210, the sorting roller 220 is provided with at least one receiving trough 221 that can only receive a single bullet 900 horizontally, the receiving trough 221 can rotate with the sorting roller 220 to a sorting receiving position that can provide the bullet 900 horizontally to enter the receiving trough 221, and the receiving trough 221 can rotate with the sorting roller 220 to a sorting receiving position that can provide the bullet 900 horizontally to enter the receiving trough 221, and the receiving trough 221 can rotate with the sorting roller 220. Rotate to the sorting and discharging station for pouring the bullets 900 from the receiving trough 221; the weighing mechanism 300 includes a receiving piece 310, a weighing drive unit 320 and a weighing sensor 330, the receiving piece 310 is provided with a weighing trough 311 capable of receiving the bullets 900 poured out from the receiving trough 221, the weighing sensor 330 can weigh the bullets 900 in the weighing trough 311, the weighing drive unit 320 is connected to the receiving piece 310 and can drive the receiving piece 310 to move to pour the bullets 900 out of the weighing trough 311.

[0048] During operation, the receiving trough 221 is at the sorting receiving station, and a single bullet 900 is horizontally fed into the receiving trough 221 from a bullet conveying device or an input channel, and the sorting rotation drive unit 210 drives the sorting roller 220 to rotate, so that the receiving trough 221 rotates to the sorting discharging station, and a single bullet 900 is poured out and enters the weighing trough 311. The weighing sensor 330 weighs the bullet 900 in the weighing trough 311. After the weighing is completed, the bullet 900 is poured out from the weighing trough 311, thereby completing the weighing of the single bullet. Due to the sorting by the sorting device 200, it is guaranteed that only one bullet falls into the weighing trough 311 each time, the weighing reliability is high, and the bullets can be horizontally transferred and weighed, with high safety.

[0049] Specifically, the bullet weighing device is equipped with a control module, and the sorting rotation drive unit 210, the weighing drive unit 320 and the weighing sensor 330 are all connected to the control module. The control module cooperates with the set sensor to control the actions of the sorting rotation drive unit 210 and the weighing drive unit 320, thereby realizing continuous weighing operations, so that the bullet weighing device has higher working efficiency.

[0050] It should be noted that, in some embodiments of the present invention, the bullet 900 being placed horizontally or rolling means that the outer peripheral surface of the bullet 900 is in contact with the supporting surface, and the length direction of the bullet 900 is roughly flush with the supporting surface.

[0051] like Fig.11 As shown, in some embodiments of the present invention, the opening of the receiving trough 221 at the sorting and receiving station faces upward to facilitate receiving the bullets 900, and the opening of the receiving trough 221 at the sorting and discharging station faces downward to facilitate pouring out the bullets 900.

[0052] like Figure 7 , Fig.10 As shown, in some embodiments of the present invention, the bullet weighing device also includes an input channel 110, which is inclined and can allow the bullet 900 to roll down. The sorting roller 220 is located at the outlet of the input channel 110. By configuring the inclined input channel 110, the bullet 900 can automatically roll down to the receiving trough 221 of the sorting roller 220 by its own weight.

[0053] It can be understood that in some embodiments of the present invention, the receiving trough 221 of the sorting roller 220 can also be directly arranged to dock with the outlet of a bullet conveying device such as a conveyor belt mechanism, a vibrating feed tray, etc., so as to realize the function of feeding the bullets into the receiving trough 221.

[0054] In some embodiments of the present invention, the receiving trough 221 is arranged on the circumferential surface of the sorting roller 220, and the opening width of the receiving trough 221 is larger than the outer diameter of the bullet 900 and smaller than twice the outer diameter of the bullet 900 to ensure that the receiving trough 221 can only receive a single bullet at a time.

[0055] like Fig.11 As shown, in some embodiments of the present invention, one side of the opening of the material receiving trough 221 is connected to the outer circumferential surface 220a of the sorting roller 220, and the other side of the opening of the material trough 221 extends along the rotation direction of the sorting roller 220 to form an extension surface 222, and the minimum distance D from the extension surface 222 to the opposite side of the opening of the material receiving trough 221 is greater than the outer diameter of the bullet 900 and less than twice the outer diameter of the bullet 900.

[0056] Specifically, the opening of the trough 221 faces the rotation direction of the sorting roller 220 to facilitate receiving the bullet 900, and the minimum distance D is 1.05 times to 1.4 times the outer diameter of the bullet 900 to ensure that the bullet 900 can smoothly enter the trough 221.

[0057] In some embodiments of the present invention, the distance from the midpoint of the minimum distance D from the extension surface 222 to the opposite side of the opening of the receiving trough 221 to the outer circumferential surface 220a of the sorting roller 220 is greater than 0.5 times the outer diameter of the bullet 900 and less than the outer diameter of the bullet 900, so as to reduce the occurrence of the next bullet being taken away by the receiving trough 221.

[0058] Specifically, one side of the opening of the receiving trough 221 is connected to the outer circumferential surface 220a of the sorting roller 220, but has a set transition distance with the outer circumferential surface 220a of the sorting roller 220 (to avoid forming a sharp angle), and the distance from the midpoint of the minimum distance D from the extended surface 222 to the opposite side of the opening of the receiving trough 221 to the outer circumferential surface 220a of the sorting roller 220 is greater than 0.5 times the outer diameter of the bullet 900 and less than the outer diameter of the bullet 900, that is, the transition distance is less than 0.5 times the outer diameter of the bullet 900, even if the next bullet partially enters the opening of the receiving trough 221, only less than half of the bullet enters the opening of the receiving trough 221, and when the sorting roller 220 rotates (such as Fig.11 The next bullet will be automatically pushed back to the input channel 110 (clockwise rotation), thereby preventing the next bullet from being taken away, and ensuring that the sorting device 200 only delivers one bullet at a time.

[0059] like Fig.11 As shown, in some embodiments of the present invention, the extension surface 222 is a curved surface, and the extension surface 222 protrudes toward the outside of the sorting roller 220 to reduce the occurrence of the bullet 900 staying on the extension surface 222.

[0060] Specifically, by protruding the extension surface 222 toward the outside of the sorting roller 220, the distance from the extension surface 222 to the outer peripheral surface of the sorting roller 220 is reduced, thereby reducing the occurrence of bullets 900 staying at the extension surface 222 and reducing the occurrence of two bullets being taken away at one time.

[0061] like Fig.11 As shown, in some embodiments of the present invention, the distance from the extension surface 222 to the outer peripheral surface of the sorting roller 220 gradually decreases along the rotation direction of the sorting roller 220 to reduce the occurrence of two bullets being taken away at one time.

[0062] like Fig.11 As shown, in some embodiments of the present invention, the receiving trough 221 rotates with the sorting roller 220 to a sorting receiving station where the bullet 900 can enter the receiving trough 221 horizontally. At this time, the receiving trough 221 is lower than the horizontal line 220b where the axis of the sorting roller 220 is located, that is, the outlet of the input channel 110 is lower than the horizontal line 220b. Even if the next bullet 900a is stacked on the bullet 900 in the receiving trough 221, the center of gravity of the bullet 900a is located outside the contact point with the bullet 900 in the receiving trough 221. When the sorting roller 220 rotates clockwise, the bullet 900a will still automatically fall back to the input channel 110, thereby reducing the situation where the receiving trough 221 takes away two bullets at a time.

[0063] like Fig.11As shown, in some embodiments of the present invention, the above structure can cooperate with the convex extension surface 222 so that the center of gravity of the stacked bullets 900a is more outward, and the stacked bullets 900a are easier to fall.

[0064] like Figure 8 , Fig.10 , Fig.11 As shown, in some embodiments of the present invention, three material receiving troughs 221 are arranged and are circumferentially spaced apart on the periphery of the sorting roller 220. The sorting rotation drive unit 210 is a servo motor or a stepper motor, etc., which can cooperate with the sensor to accurately control the position of the material receiving trough 221 to realize accurate material discharging and receiving functions, and can cooperate with the control module to realize continuous material receiving and discharging operations. The three material receiving troughs 221 can continuously perform material receiving and unloading operations in sequence to improve the efficiency of weighing.

[0065] It can be understood that, in some embodiments of the present invention, the receiving trough 221 can be set to one, two, four or more, which will not be described in detail here.

[0066] like Figures 1 to 3 As shown, in some embodiments of the present invention, the bullet weighing device also includes a bullet conveying device 400, and the bullet conveying device 400 can deliver the bullet 900 to the input channel 110 to achieve automatic delivery of the bullet 900 and improve work efficiency.

[0067] like Figure 4 As shown, in some embodiments of the present invention, the bullet conveying device 400 includes a conveyor belt 410 that can be used to horizontally place bullets 900 and a conveyor belt driving unit 420 that can drive the conveyor belt 410 to move. A feed side push mechanism 430 is arranged on the side of the position of the conveyor belt 410 corresponding to the input channel 110. The feed side push mechanism 430 can push the bullets 900 on the conveyor belt 410 laterally to the input channel 110, thereby realizing the continuous feeding of the bullets 900.

[0068] Specifically, the bullets 900 on the conveyor belt 410 can be placed through a vibrating plate, a barrel or manually. The conveyor belt 410 is equipped with a sensor such as an infrared sensor to determine the position of the bullets 900 on the conveyor belt 410, and cooperate with the control module to control the action of the feed side push mechanism 430 to achieve continuous feeding of the bullets 900.

[0069] Of course, in the specific implementation process, the bullet conveying device 400 can also adopt a chain conveying mechanism, etc.

[0070] like Figure 4 As shown, in some embodiments of the present invention, the conveyor belt driving unit 420 includes two pulleys arranged on the conveyor frame and a motor capable of driving the pulleys to roll, thereby realizing the conveyance of the bullets 900.

[0071] like Figure 4 As shown, in some embodiments of the present invention, the feed side push mechanism 430 is a cylinder push mechanism. Of course, in a specific process, the feed side push mechanism 430 can also use a linear drive mechanism such as an electric cylinder, an oil cylinder, a spur rack mechanism, etc. to realize the lateral pushing of the bullets 900 on the conveyor belt 410.

[0072] like Figure 7 , Fig.10 As shown, in some embodiments of the present invention, the bullet weighing device also includes a connecting channel 120, which is inclined and located between the sorting device 200 and the weighing mechanism 300. The bullets 900 poured out from the receiving trough 221 fall into the connecting channel 120, and the weighing trough 311 corresponds to the outlet of the connecting channel 120. The bullet transportation between the sorting device 200 and the weighing mechanism 300 is realized through the connecting channel 120, thereby realizing continuous weighing operation.

[0073] Of course, in the specific implementation process, the connecting channel 120 may not be configured, and the weighing trough 311 may be set to correspond to the receiving trough 221 at the sorting and discharging station, and the bullets 900 in the receiving trough 221 may be directly poured into the weighing trough 311.

[0074] like Fig. 9 , Fig.10 As shown, in some embodiments of the present invention, the bottom of the weighing trough 311 is a V-shaped structure to facilitate the stable placement of the lying bullet 900 and improve the weighing accuracy.

[0075] like Figure 7 , Fig. 9 As shown, in some embodiments of the present invention, the material receiving member 310 is a rotating member, and the material receiving member 310 is provided with at least one weighing slot 311. The weighing drive unit 320 can drive the material receiving member 310 to rotate, and by rotating the material receiving member 310, the weighing slot 311 can be rotated to a position for receiving and dumping the bullets 900.

[0076] Specifically, the weighing drive unit 320 is a stepper motor or a servo motor, which can cooperate with the sensor to accurately control the position of the weighing slot 311 to achieve accurate material discharging and receiving functions, and can cooperate with the control module to achieve continuous material receiving and discharging operations to improve the efficiency of weighing.

[0077] like Fig. 9 , Fig.10 As shown, in some embodiments of the present invention, the material receiving piece 310 is equipped with four weighing slots 311, and the four weighing slots 311 are distributed in sequence at the circumferential positions of the material receiving piece 310. By controlling the rotation position of the material receiving piece 310, functions such as receiving bullets, weighing bullets, and dumping bullets are realized, and the four weighing slots 311 can be cyclically weighed in sequence, which greatly improves the weighing efficiency.

[0078] It can be understood that, in some embodiments of the present invention, the material receiving member 310 may be provided with one, two, three, five or more weighing slots 311, which will not be described in detail herein.

[0079] like Fig. 9 , Fig.10 As shown, in some embodiments of the present invention, the weighing sensor 330 is arranged at the bottom of the weighing drive unit 320, and is capable of weighing the docking material 310 and the weighing drive unit 320, that is, by weighing the docking material 310 and the weighing drive unit 320 as a whole, the weight of a single bullet 900 can be obtained by calculating the increased weight.

[0080] Specifically, Fig. 9 As shown, the weighing drive unit 320 is installed to the weighing sensor 330 through a bracket, and the material receiving piece 310 is connected to the output shaft of the weighing drive unit 320. When the bullet falls into the weighing slot 311, the weighing sensor 330 can obtain the overall weight of the material receiving piece 310, the weighing drive unit 320 and the bullet at this time, and cooperate with the control module to deduct the initial weight of the material receiving piece 310 and the weighing drive unit 320 to obtain the weight of a single bullet.

[0081] It can be understood that, in some embodiments of the present invention, the weighing sensor 330 may also be disposed in the weighing slot 311 to directly weigh the bullets that fall into the weighing slot 311 .

[0082] Reference Figures 1 to 3 According to the second aspect of the present invention, the bullet weighing and sorting system comprises: at least one bullet weighing device 800 according to any one of the first aspect of the present invention and a bullet output device 500 connected to the bullet weighing device 800, the bullet output device 500 can receive the bullets 900 poured out from the weighing trough 311 and can drive the bullets 900 to move, at least one discharge side pushing mechanism 510 is arranged on one side of the bullet output device 500, and a classification receiving assembly is arranged on the other side of the bullet output device 500, the discharge side pushing mechanism 510 can push the bullets 900 of the bullet output device 500 laterally to the classification receiving assembly to meet the weighing, classification and screening requirements of the bullets.

[0083] Specifically, the control module can record the weight of each bullet and cooperate with the sensor to mark the output of the bullet continuously. When the bullet of the set weight is delivered to the discharging side pushing mechanism 510, the discharging side pushing mechanism 510 is actuated to push the bullet laterally out of the discharging side pushing mechanism 510. The bullet can then fall into the set classification receiving component, thereby completing the weighing and screening of the bullet.

[0084] like Figures 1 to 3As shown, in some embodiments of the present invention, the classification material receiving component includes a classification hopper 610 and a classification material receiving tray 620 corresponding to the classification hopper 610. The classification hopper 610 is arranged on the opposite side of the discharge side pushing mechanism 510, and the classification material receiving tray 620 is arranged below the classification hopper 610, thereby satisfying the function of receiving materials.

[0085] It can be understood that in some embodiments of the present invention, a material conveying line can also be set under the classification hopper 610 to directly deliver bullets of corresponding specifications to the set process.

[0086] In some embodiments of the present invention, the discharging side push mechanism 510 and the classification and receiving components are configured in multiple groups to meet the classification and screening of bullets of various specifications.

[0087] like Figure 3 , Figure 7 , Fig.10 As shown, in some embodiments of the present invention, an output channel 130 is provided between the bullet output device 500 and the weighing mechanism 300, and the output channel 130 is inclined, and the bullets 900 poured out from the weighing slot 311 fall into the output channel 130, and the outlet of the output channel 130 corresponds to the inlet of the bullet output device 500, so as to realize the automatic delivery of the bullet, and improve the position accuracy of the bullet when it is delivered, which is convenient for screening.

[0088] It is understandable that in some embodiments of the present invention, the output channel 130 may not be configured, and the pouring position of the weighing tank 311 may correspond to the bullet output device 500, and the weighed bullets may be directly poured into the bullet output device 500.

[0090] like Figure 5 As shown, in some embodiments of the present invention, the bullet output device 500 is a chain conveying mechanism, which includes a chain 520 and a chain driving unit 530 capable of driving the chain 520 to move. The bullet 900 can fall onto the top of the chain 520 to realize the conveyance of the bullet 900. By conveying the bullet 900 through the chain conveying mechanism, the conveying position accuracy of the bullet 900 can be improved, so that the discharging side push mechanism 510 can accurately push out the bullet.

[0091] Specifically, the chain drive unit 530 includes a motor and a sprocket arranged on the output frame 540. The chain 520 is formed by connecting a plurality of chain links. The concave structure on the chain 520 is conducive to positioning the bullet, reducing the occurrence of rolling and displacement of the bullet, and improving the delivery accuracy of the bullet.
