Description
본 발명은 총탄(銃彈)의 탄피(彈皮)를 제조하는 과정에서 탄피의 입구 부분에 변형이 발생한 것을 자동 연속으로 검사하고 이를 분류/선별하는 장치에 관한 것이다.The present invention relates to a device for automatically and continuously inspecting for deformation at the entrance of a bullet shell during the process of manufacturing the bullet shell and classifying/selecting the same.
주지된 바와 같이 총탄은 탄피와 탄두 그리고 화약, 뇌관 등으로 구성되는데, 탄피의 내부에 화약을 채우고 입구에 탄두를 결합하여 완성된다.As is well known, a bullet is composed of a cartridge case, a bullet, gunpowder, a primer, etc., and is completed by filling gunpowder inside the cartridge case and attaching the bullet to the opening.
이러한 탄피는 통상 자동화 시스템에 의해 생산되는데 간혹 탄피의 입구의 일부분이 찌그러지거나 길이가 불량 성형되는 경우가 있어, 불량 탄피가 다음의 공정이나 자동 이송 과정에서 정확한 장착이나 결합, 이동이 불가능하여 자동생산 라인에 적체가 발생하므로 공정 전체가 중단되는 문제로 이어지며, 탄두의 조립에도 문제가 발생하므로 전체적인 총탄의 생산에 막대한 차질을 빚거나 불량 탄환을 생산하게 되는 문제로 이어졌던 것이다.These cartridges are usually produced by an automated system, but occasionally a part of the cartridge entrance may be distorted or the length may be improperly formed. As a result, the defective cartridges cannot be correctly installed, combined, or moved during the next process or automated transport process, causing a backlog in the automated production line, which in turn causes the entire process to stop. In addition, problems may also occur with the assembly of the bullets, which can cause significant disruption to the overall production of bullets or lead to the production of defective bullets.
이러한 탄피의 검사는 종래 수작업으로 이루어졌는데, 시각에 의존한 검사로는 정확한 불량 선별이 어려웠고, 이에 따라 자동으로 신속하고 정확한 검사기 이루어지도록 하는 기술이 필요하였다.Inspection of these cartridges was previously done manually, but it was difficult to accurately select defective cartridges through inspection based on visual inspection. Accordingly, technology was needed to enable automatic, rapid, and accurate inspection.
상기 문제점과 필요성에 의해 안출된 본 발명은 탄피를 자동으로 공급하여 한 개씩 회전이동하는 중에 자동으로 탄피 입구의 내외경과 전체 높이의 불량을 감지하여 불량과 정품을 선별할 수 있도록 함으로써 불량 탄피의 선별을 정확하고 신속하게 이룩할 수 있도록 하려는 것으로, 이에 따른 총탄 생산의 생산성과 효율성을 기하는 것을 목적으로 한다.The present invention, which was conceived due to the above problems and necessity, automatically detects defects in the inner and outer diameters and the overall height of the cartridge inlet while cartridges are automatically supplied and rotated one by one, thereby enabling the sorting of defective cartridges to be accurately and quickly accomplished, thereby improving the productivity and efficiency of bullet production.
상기 목적을 달성하기 위한 본 발명은, 공급피더를 이용하여 원판형 회전 테이블에 일정한 각도 상의 외주면에 탄피가 세워진 상태로 인입되도록 다수의 검사홈을 구성하여 공급피더에 의하여 탄피가 연속 자동으로 공급되도록 하고, 회전 테이블에 의해 이동하는 탄피의 상부에 회전 테이블과 함께 회전하면서 탄피를 검사하는 검사헤드를 설치하되, 검사헤드의 저면에는 탄피의 외경 및 높이를 검사하기 위하여 탄피의 정상 외경와 동일한 내경을 갖는 검사내면을 구성하고, 검사헤드가 최대 하강하였을 때 탄피의 정상높이와 일치하는 검사상면을 구성하며, 검사헤드의 내부에는 정상적인 탄피의 내경과 동일한 외경을 갖는 검사핀을 설치한 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that a plurality of inspection grooves are formed so that a cartridge case is introduced in a state where the cartridge case is erected on an outer surface at a predetermined angle on a disk-shaped rotary table using a supply feeder, so that the cartridge case is continuously and automatically supplied by the supply feeder, and an inspection head is installed on the upper part of the cartridge case moving by the rotary table while rotating together with the rotary table to inspect the cartridge case, wherein an inspection inner surface having an inner diameter identical to the normal outer diameter of the cartridge case is formed on the lower surface of the inspection head in order to inspect the outer diameter and height of the cartridge case, and an inspection upper surface matching the normal height of the cartridge case when the inspection head is lowered to the maximum is formed, and an inspection pin having an outer diameter identical to the inner diameter of a normal cartridge case is installed inside the inspection head.
또한, 상기 검사헤드를 구비하는 검사유닛은 회전 테이블의 검사홈 숫자와 같으면서 동일한 위치에 설치하고, 회전 테이블의 상부에 고정된 원통캠의 캠홈을 따라 승강하도록 검사유닛의 일측에는 캠홈에 삽입되어 승강하는 캠롤러가 측면에 설치되어 승강작용을 하는 캠승강판을 구성하였으며, 캠승강판 상부에는 검사작동시 탄피를 눌러주기 위한 누름핀이 검사유닛의 중앙을 관통하여 설치되며, 캠승강판의 중단에는 검사헤드를 작동시키기 위한 검사작동관을 구성함을 특징으로 한다.In addition, the inspection unit equipped with the inspection head is installed at the same position as the number of inspection grooves of the rotary table, and is configured with a cam roller installed on the side of the inspection unit to be inserted into the cam groove and to be elevated along the cam groove of the cylindrical cam fixed to the upper part of the rotary table, and a cam elevation plate that performs an elevation operation is configured, and a press pin for pressing a cartridge case during inspection operation is installed through the center of the inspection unit on the upper part of the cam elevation plate, and an inspection operation pipe for operating the inspection head is configured in the middle of the cam elevation plate.
아울러 검사유닛의 검사작동으로 탄피의 입구에 불량이 발생한 것을 감지하도록 측정유닛을 설치하여 자동으로 불량을 판단하도록 하였다.In addition, a measuring unit was installed to detect defects at the entrance of the cartridge case during the inspection operation of the inspection unit and automatically determine the defects.
상기와 같은 본 발명에 의하면 탄피가 공급되어 회전 테이블에서 이동하는 중에 탄피의 입구 내경과 외경 및 높이를 한꺼번에 검사하여 정상품과 불량품을 신속하고 정확하게 선별할 수 있게 되므로 불량품 생산을 효과적으로 방지할 수 있으며, 총탄의 생산성을 높일 수 있는 장점이 있다.According to the present invention as described above, the inner diameter and outer diameter and height of the cartridge inlet can be inspected simultaneously while the cartridge is supplied and moves on a rotary table, thereby enabling normal products and defective products to be quickly and accurately sorted out, thereby effectively preventing the production of defective products and having the advantage of increasing the productivity of bullets.
아울러 상기와 같은 검사 과정에서 탄피 입구의 미세한 불량이 자동으로 교정되는 효과도 얻을 수 있다.In addition, the inspection process described above can also have the effect of automatically correcting minor defects in the cartridge entrance.

이하, 본 발명에 의한 "탄피 결함 검사 및 분류장치"에 대하여 구성을 상세히 설명하고자 하는바, 이러한 구성의 설명은 본 발명을 구현하기 위한 실시 예를 기준으로 한 것으로서, 본 발명이 추구하는 기술적 사상을 본 문서에 기재된 실시 예에 기재된 형태로 한정하려는 것이 아니며, 본 발명의 실시 예의 다양한 변경(modifications), 균등물(equivalents) 및/또는 대체물(alternatives)을 포함하는 것으로 이해되어야 할 것이다.Hereinafter, the configuration of the "cartridge defect inspection and classification device" according to the present invention will be described in detail. The description of the configuration is based on an embodiment for implementing the present invention, and is not intended to limit the technical idea pursued by the present invention to the form described in the embodiment described in this document, and should be understood to include various modifications, equivalents, and/or alternatives of the embodiment of the present invention.
아울러, 본 발명의 실시 예를 설명하면서 본 발명의 구성에 따른 작용 효과를 명시적으로 기재하여 설명하지 않았을지라도, 해당 구성에 의해 예측 가능한 효과 또한 인정되어야 함은 당연하다.In addition, even if the operational effects according to the configuration of the present invention are not explicitly described and explained while describing the embodiments of the present invention, it is natural that the effects that can be predicted by the configuration should also be acknowledged.
본 발명에 의한 검사 및 분류장치는 크게 탄피(1)가 한 개씩 고정되어 회전하면서 검사가 이루어지도록 하는 회전 이송부(10)와, 상기 회전 이송부(10)의 상부에 설치되어 회전 이송부(10)와 동시에 회전하면서 검사를 진행하는 검사장치부(20), 그리고 회전 이송부(10)에 탄피(1)를 정렬하여 공급하는 공급피더(30)로 이루어진다.The inspection and classification device according to the present invention is largely composed of a rotating transport unit (10) in which cartridges (1) are fixed one by one and rotated to perform inspection, an inspection device unit (20) installed on the upper portion of the rotating transport unit (10) to perform inspection while rotating simultaneously with the rotating transport unit (10), and a supply feeder (30) that aligns and supplies cartridges (1) to the rotating transport unit (10).
회전 이송부(10)는 원판형의 회전 테이블(11)에 일정한 각도 상의 외주면에 탄피(1)가 세워진 상태로 인입되도록 다수의 검사홈(11-1)이 구성되어 하부의 구동모터(M)에 의해 회전하도록 구성되고 있고, 회전 테이블(11)의 저면과 측면 일부를 감싸면서 고정된 상태로 회전 테이블(11)의 회전을 가이드하도록 구성된 회전 가이드(12)가 구성되는데, 이러한 회전 가이드(12)에는 공급피더(30)가 연결되어 탄피(1)가 하나씩 유입되도록 하는 유입통로(12-1)가 형성되어 있고 검사가 완료되어 정상품으로 판단된 탄피(1)가 배출되는 부분에는 하부로 배출구멍(12-2)을 형성하였으며, 배출구멍(12-2)을 통과한 부분으로부터는 회전 테이블(11)의 측면을 감싸는 부분이 삭제되어 불량품이 배출될 수 있도록 하였다.The rotary transport unit (10) is configured to have a plurality of inspection grooves (11-1) configured to allow cartridges (1) to be introduced in a standing state on the outer surface of a disc-shaped rotary table (11) at a certain angle and to rotate by a driving motor (M) at the bottom, and a rotary guide (12) configured to guide the rotation of the rotary table (11) in a fixed state while surrounding the bottom and a part of the side of the rotary table (11) is configured, and a supply feeder (30) is connected to this rotary guide (12) and an inlet passage (12-1) is formed through which cartridges (1) are introduced one by one, and a discharge hole (12-2) is formed at the bottom where cartridges (1) that have been inspected and judged to be normal are discharged, and a part that surrounds the side of the rotary table (11) is removed from the part that has passed through the discharge hole (12-2) so that defective products can be discharged.
배출구멍(12-2)의 하부에는 평상시에 개방되어 있다가 검사장치부(20)의 작동에 의해 불량이라고 판단된 탄피(1)가 이동할 경우 차단작용을 하여 배출구멍(12-2)으로 배출되지 않도록 하는 차단판(13)이 구비되는데, 차단 실린더(13-1)에 의해 작동하여 배출구멍(12-2)의 하부를 막아주는 것이다.A blocking plate (13) is provided at the bottom of the discharge hole (12-2) to block a cartridge case (1) that is determined to be defective by the operation of the inspection device (20) when it moves, thereby preventing it from being discharged through the discharge hole (12-2). This plate is operated by a blocking cylinder (13-1) to block the bottom of the discharge hole (12-2).
배출구멍(12-2)의 상부에는 탄피(1)의 배출이 원활하도록 정상품이 통과할 때만 작용하는 공기분사구(13-2)가 설치된다.An air jet (13-2) is installed at the top of the discharge hole (12-2) to ensure smooth discharge of the cartridge case (1) only when a normal product passes through.
배출구멍(12-2)이 경과한 위치이면서 회전 가이드(12)가 회전 테이블(11)의 측면을 감싸지 않은 부분의 회전 테이블(11) 상부에는 회전 테이블(11)의 중심으로부터 검사홈(11-1) 안쪽에서 시작하여 점차 바깥 방향으로 휘어지는 형태의 불량 배출 가이드(14)를 설치하였는데, 검사에서 불량으로 판단된 탄피(1)가 회전 테이블(11)에 의해 회전하다가 불량 배출 가이드(14)에 마찰되면서 점차 외부 방향으로 밀려나면서 불량수집통으로 배출되도록 한 것이다.A defective discharge guide (14) that starts from the inside of the inspection groove (11-1) from the center of the rotary table (11) and gradually curves outward is installed on the upper part of the rotary table (11) at a position where the discharge hole (12-2) has passed and where the rotary guide (12) does not wrap around the side of the rotary table (11). This is so that a cartridge case (1) judged to be defective in the inspection is rotated by the rotary table (11) and is gradually pushed outward as it rubs against the defective discharge guide (14) and is discharged into a defective collection container.
상기 회전 테이블(11)의 상부에는 회전 테이블(11)과 같이 회전을 하면서 검사작용을 하는 검사장치부(20)가 구성되는데, 회전 테이블(11)과 동시에 회전하는 주축(11-2)에 연결된 회전 지지대(15)에 의해 회전하는 검사유닛(20') 및 검사유닛(20')의 일측 위치에 고정되어 검사유닛(20')의 작동상태를 감지하여 정상 여부를 판단하는 측정유닛(20")으로 구성된다.On the upper part of the above rotary table (11), an inspection device (20) that performs an inspection operation while rotating like the rotary table (11) is configured, and is composed of an inspection unit (20') that rotates by a rotary support (15) connected to a main shaft (11-2) that rotates simultaneously with the rotary table (11), and a measuring unit (20") that is fixed to one side of the inspection unit (20') and detects the operating status of the inspection unit (20') to determine whether it is normal.
검사유닛(20')은 회전 테이블(11)의 검사홈(11-1) 숫자와 같으면서 동일한 위치에 설치되고 검사유닛(20')의 검사헤드(21)가 승강을 하면서 하강시 검사가 이루어지며, 충분한 하강이 이루어지지 않거나 과도한 하강이 이루어지면 불량으로 판정되도록 한 것이다.The inspection unit (20') is installed in the same position as the number of inspection grooves (11-1) of the rotary table (11), and inspection is performed when the inspection head (21) of the inspection unit (20') is raised and lowered. If the lowering is not sufficient or excessive, it is judged as defective.
상기 모든 검사유닛(20')은 회전 테이블(11)의 상부에 캠지지대(16-1)에 의해 고정된 원통캠(16)의 캠홈(16-2)을 따라 승강하는데, 검사유닛(20')의 일측에는 캠홈(16-2)에 삽입되어 승강하는 캠롤러(22)가 측면에 설치되어 승강작용을 하는 캠승강판(22-1)이 구성되고, 캠승강판(22-1) 상부에는 검사작동시 탄피(1)를 눌러주기 위한 누름핀(24)이 검사유닛(20')의 검사작동관(25) 중앙을 관통하여 설치되며, 과도한 하강이 방지되면서 누름핀(24)이 탄성을 갖도록 핀스프링(24-1)에 지지되도록 설치된다.All of the above inspection units (20') are raised and lowered along the cam groove (16-2) of the cylindrical cam (16) fixed to the upper part of the rotary table (11) by the cam support (16-1). On one side of the inspection unit (20'), a cam lifting plate (22-1) is formed, which has a cam roller (22) installed on the side to be raised and lowered by being inserted into the cam groove (16-2) and performs an raising and lowering operation. On the upper part of the cam lifting plate (22-1), a push pin (24) for pressing the cartridge case (1) during inspection operation is installed through the center of the inspection operation tube (25) of the inspection unit (20'), and is installed so that the push pin (24) is supported by a pin spring (24-1) so that it has elasticity while preventing excessive lowering.
또한, 캠승강판(22-1)의 중단에는 검사헤드(21)를 작동시키기 위한 검사작동관(25)을 연결설치하였으며, 검사작동관(25)의 내부에는 상기한 누름핀(24)이 통과하여 검사작동 전의 위치에서는 누름핀(24)이 검사헤드(21)보다 아래로 돌출된 상태가 되도록 조립되는 것이다. 검사작동관(25)의 외부에는 검사스프링(25-1)을 설치하여 검사작동관(25)이 하강시 탄성을 가하도록 하였으며, 불량 탄피에 의하여 충분히 하강하지 않을 경우 검사스프링(25-1)이 압축되면서 하강하지 않는 높이를 수용하게 된다.In addition, an inspection operation pipe (25) for operating the inspection head (21) is connected and installed at the stop of the cam lifting plate (22-1), and the above-mentioned push pin (24) passes through the inside of the inspection operation pipe (25) so that the push pin (24) protrudes lower than the inspection head (21) before the inspection operation. An inspection spring (25-1) is installed on the outside of the inspection operation pipe (25) so that the inspection operation pipe (25) applies elasticity when lowered, and when it does not descend sufficiently due to a defective cartridge case, the inspection spring (25-1) is compressed to accommodate the height at which it does not descend.
상기 검사작동관(25)의 하단에는 검사헤드(21)가 설치되는데, 검사헤드(21)의 저면에는 탄피(1)의 외경 및 높이를 검사하기 위하여 탄피(1)의 정상 외경와 동일한 내경을 갖는 검사내면(21-1)을 구성하고, 검사헤드(21)가 최대 하강하였을 때 탄피(1)의 정상높이와 일치하는 검사상면(21-2)을 구성하였다.An inspection head (21) is installed at the bottom of the above inspection operation tube (25). In order to inspect the outer diameter and height of the cartridge (1), an inspection inner surface (21-1) having the same inner diameter as the normal outer diameter of the cartridge (1) is formed on the bottom surface of the inspection head (21), and an inspection upper surface (21-2) is formed that matches the normal height of the cartridge (1) when the inspection head (21) is lowered to the maximum.
그리고 검사헤드(21)의 내부에는 검사핀(21-3)을 결합하였는데, 검사핀(21-3)의 외경은 정상적인 탄피(1)의 내경과 동일한 것이며, 상기 검사내면(21-1)의 입구와 검사핀(21-3)의 선단부에는 경사면을 형성하여 탄피(1)의 내외부로 잘 유입되도록 하였다.And, an inspection pin (21-3) is combined inside the inspection head (21). The outer diameter of the inspection pin (21-3) is the same as the inner diameter of a normal cartridge case (1), and an inclined surface is formed at the entrance of the inspection inner surface (21-1) and the tip of the inspection pin (21-3) to ensure proper introduction into the inside and outside of the cartridge case (1).
상기 검사유닛(20')의 상부 일측에는 검사작동관(25)과 일체화되어 검사작동관(25)과 함께 승강하도록 감지블록(26)를 설치하였으며, 검사유닛(20')의 외부 일측 위치, 즉 캠홈(16-2)에 의해 검사유닛(20')이 최대 하강하는 위치에 고정되는 측정유닛(20")은 상기 감지블록(26)이 이동하다가 감지블록(26)이 정상적인 높이를 위아래로 벗어나면 그 차이를 감지하여 불량을 판단하도록 하였는데, 승강대(27)의 일측에 구성되어 감지블록(26)의 저면에 밀착되는 감지롤러(28)를 설치하였고 승강대(27)의 저부에는 하강시 스프링에 의해 탄성을 받아 복귀가능하도록 하면서 승강대(27)가 하강하는 정도를 정밀하게 측정하는 인디게이터(29)를 설치한 것이다.On the upper side of the above inspection unit (20'), a detection block (26) is installed so as to be integrated with the inspection operation pipe (25) and to be raised and lowered together with the inspection operation pipe (25). A measuring unit (20"), which is fixed to an external side of the inspection unit (20'), that is, a position where the inspection unit (20') descends the most, is configured to detect the difference between the detection block (26) and the normal height when the detection block (26) moves and to determine a defect. A detection roller (28) is installed on one side of the elevator (27) and is in close contact with the bottom surface of the detection block (26). An indicator (29) is installed on the bottom of the elevator (27) so as to be able to return by receiving elasticity from a spring when lowered, and to precisely measure the degree to which the elevator (27) descends.
상기와 같이 구성된 본 발명의 작용에 대하여 살펴본다.Let us examine the operation of the present invention configured as described above.
회전 테이블(11)과 검사유닛(20')이 구동모터(M)의 힘과 주축(11-2)의 회전으로 회전을 하고 있는 상태에서 공급피더(30)에 의해 정렬된 상태로 공급되는 탄피(1)가 회전 테이블(11)의 검사홈(11-1)에 하나씩 유입된다.While the rotary table (11) and the inspection unit (20') are rotating by the power of the driving motor (M) and the rotation of the main shaft (11-2), the cartridges (1) supplied in an aligned state by the supply feeder (30) are fed one by one into the inspection groove (11-1) of the rotary table (11).
검사홈(11-1)에 안착된 탄피(1)가 회전 테이블(11)의 회전에 의해 이동을 하고 있는 상태에서 캠홈(16-2)에 의해 검사유닛(20')이 하강하는데, 고정된 원통캠(16)의 외면에 형성된 캠홈(16-2)을 따라 캠롤러(22)가 승강을 하면서 이동을 하고, 캠롤러(22)의 승강에 따라 캠승강판(22-1)에 의해 설치된 검사유닛(20')이 승강을 하면서 검사작동을 시작하게 되는데, 검사헤드(21)보다 아래로 돌출된 누름핀(24)이 먼저 탄피(1)의 내부 바닥에 닿으면서 탄피(1)가 움직이지 못하도록 눌러주게 되고 이때 핀스프링(24-1)이 압축되면서 강한 고정력을 부여한다. While the cartridge case (1) settled in the inspection home (11-1) is moving by the rotation of the turntable (11), the inspection unit (20') is lowered by the cam home (16-2), the cam roller (22) moves up and down along the cam home (16-2) formed on the outer surface of the fixed cylindrical cam (16), and as the cam roller (22) is raised and lowered, the inspection unit (20') installed by the cam lifting plate (22-1) starts the inspection operation by raising and lowering. The push pin (24) protruding below the inspection head (21) first touches the inner bottom of the cartridge case (1) to press the cartridge case (1) so that it does not move, and at this time, the pin spring (24-1) is compressed to provide a strong fixing force.
검사유닛(20')이 조금 더 하강을 하면 검사헤드(21)가 탄피(1)를 향해 하강하는데, 검사헤드(21)의 검사내면(21-1)이 탄피(1)의 외경을 감싸면서 하강을 하고 동시에 검사핀(21-3)의 외경이 탄피(1)의 내경에 꼭 맞게 유입되며, 검사헤드(21)의 검사상면(21-2)은 탄피의 상면에 밀착된다.When the inspection unit (20') descends a little more, the inspection head (21) descends toward the cartridge case (1), and the inspection inner surface (21-1) of the inspection head (21) descends while surrounding the outer diameter of the cartridge case (1), and at the same time, the outer diameter of the inspection pin (21-3) is inserted so as to fit the inner diameter of the cartridge case (1), and the inspection upper surface (21-2) of the inspection head (21) is in close contact with the upper surface of the cartridge case.
이러한 과정에서 탄피의 외경 또는 내경이 설계된 치수에 맞지 않게 생산되었거나, 성형과정이나 이송중 찌그러지는 등의 문제가 발생한 경우에는 검사헤드(21) 또는 검사핀(21-3)이 걸리게 되므로 검사작동관(25) 전체가 충분한 하강이 이루어지지 못할 것이며, 탄피의 길이가 과도하게 길거나 찌그러져 돌출된 경우에도 마찬가지로 하강이 불충분할 것이다.In this process, if the outer or inner diameter of the cartridge is not produced to the designed dimensions, or if a problem occurs, such as being crushed during the molding process or transport, the inspection head (21) or the inspection pin (21-3) will become caught, and the entire inspection operating tube (25) will not descend sufficiently. In addition, if the length of the cartridge is excessively long or is crushed and protrudes, the descent will also be insufficient.
상기와 같이 검사작동관(25)의 하강이 불충분 상태 또는 충분한 하강이 이루어진 상태로 검사유닛(20')이 회전을 이어가게 되면, 감지블록(26)이 측정유닛(20")의 감지롤러(28)를 터치하는 작용을 하는데, 이때 감지롤러(28)의 하강 정도에 따라 인디케이터(29)가 정상품과 불량품을 구분하게 되는 것이다.As described above, when the inspection unit (20') continues to rotate with the lowering of the inspection operation tube (25) insufficient or sufficient, the detection block (26) acts to touch the detection roller (28) of the measuring unit (20"), and at this time, the indicator (29) distinguishes between normal and defective products depending on the degree of lowering of the detection roller (28).
인디게이터(29)가 정상으로 판단할 경우 회전 가이드(12)의 저면에 형성된 배출구멍(12-2)이 차단판에 의해 막혀있지 않게 되므로 정상품인 탄피가 배출구멍(12-2)으로 배출되어 다음의 공정으로 공급되는 것이며, 인디게이터(29)가 불량으로 판단한 경우 차단 실린더(13-1)가 작동하여 차단판(13)이 배출구멍(12-2)을 막게 되므로 탄피는 배출구멍(12-2)으로 배출되지 않고 계속 이동하게 되고, 불량 배출가이드(14)에 의해 검사홈(11-1)을 서서히 이탈하면서 불량품 배출통으로 배출되는 것이다.If the indicator (29) determines that it is normal, the discharge hole (12-2) formed on the bottom surface of the rotary guide (12) is not blocked by the blocking plate, so the normal cartridge is discharged through the discharge hole (12-2) and supplied to the next process. If the indicator (29) determines that it is defective, the blocking cylinder (13-1) operates so that the blocking plate (13) blocks the discharge hole (12-2), so the cartridge is not discharged through the discharge hole (12-2) but continues to move, and is discharged into the defective cartridge discharge container while slowly leaving the inspection groove (11-1) by the defective discharge guide (14).
본 발명은 이상과 같은 작용으로 입구 부분에 불량이 발생한 탄피를 효율적으로 선별하게 되는 것이며, 불량 총탄을 생산하는 확률을 완벽히 낮추면서 생산능률을 향상시킬 수 있는 것이다.The present invention efficiently selects cartridges with defects in the inlet portion through the above-described operation, and can improve production efficiency while completely reducing the probability of producing defective bullets.
