본 발명은 제품포장용필름을 일정량씩 순차적으로 송출할 수 있도록 한 필름자동송출장치에 관한 것이다.The present invention relates to an automatic film dispensing device that can sequentially send a film for product packaging by a predetermined amount.

종래에는 필름을 일정량씩 순차적으로 송출할 때 필림이 권취된 로울러의 회전수를 제어하여 필림을 송출함으로서 로울러에 권취된 필림의 외경이 사용량에 따라 점차적으로 줄어들므로서 필림이 권취된 로울러의 회전수와 필림이 풀리는 양이 일정하지 못하여 로울러와 연결된 모터의 제어에 의한 필림 송출 어려움이 있었으며 특히 일정량씩 절단을 요하는 공정에서는 일정길이 이상 또는 이하로 송출하는 경우가 발생되는 불량품이 다량 발생하곤 하였다.Conventionally, when the film is sequentially sent out by a predetermined amount, the number of rotations of the rollers on which the film is wound is reduced by controlling the rotation speed of the rollers on which the film is wound so that the outer diameter of the film wound on the roller gradually decreases according to the usage amount. Since the amount of unwinding and film was not constant, film delivery was difficult due to the control of the motor connected to the roller. Especially, in a process requiring a certain amount of cutting, a large amount of defective products that occurred when a certain length or more was sent out were generated.

따라서 본 발명은 상기한 문제점을 해소하기 위하여 안출한 것으로서 그 목적으로는 로울러에 권취된 제품포장용 필림의 외경과 관계없이 항상 일정량의 필림을 공급할 수 있도록 한 이하 첨부된 도면에 따라 그 구성을 상세히 설명하면 다음과 같다.Therefore, the present invention has been made in order to solve the above problems, the purpose of the present invention will be described in detail according to the accompanying drawings so as to always supply a certain amount of film regardless of the outer diameter of the product packaging film wound on the roller. Is as follows.

모터(1) 축과 제품포장용필림(3)이 권취된 필림로울러(2)축을 벨트(1')로 연결하고, 이송로울러(8)와 (8') 및 (8＂) 사이에 리미트스위치(5)를 하부측에 부착시킨 렉기어(4)와 (4')를 입설시켜 상하이송로울러(6)의 양단에 부착된 원형기어(7)(7')를 상기 렉기어(4)(4')에 각각 치합시키고 일측에 상승로울러(10)(10')와 (11)(11')를 상하2단으로 형성하되, 상승로울러(10)의 축과 타이머(15)가 부착된 모터(9)의 축을 벨트(9')로 연결하며 상기 상승로울러(11)(11')의 상부에 벌림기(12)와 벨트(14) (14')로 연결된 벌림로울러(13)(13')형성하고, 벌림기 상단부측에 핀거(16)(16') 형성시킨 제품포장용 필림자동송출장치이다.The motor (1) shaft and the film roller (2) shaft on which the product packaging film (3) is wound are connected with the belt (1 '), and the limit switch (8) between the feed rollers (8) and (8') and (8 ＂) 5) The gears 4 and 4 'attached to the lower side are placed in the circular gears 7 and 7' attached to both ends of the Shanghai Song roller 6, respectively. ') And the up rollers 10, 10' and (11), 11 'are formed in two stages up and down on one side, respectively, the shaft of the up roller 10 and the motor having the timer 15 attached thereto ( 9) connecting the shaft of the belt 9 'to the top of the lift rollers 11 and 11' and the open rollers 12 and 13 'connected to the belts 14 and 14'. And an automatic film feeder for product packaging formed with pingers 16 and 16 'formed on the upper end of the separator.

이와 같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다. 타이머(15)에 의해 모터(9)를 동작시키면 상승로울러(10)(10')와 (11)(11') 및 벌림(13)(13')의 회전으로 필림이 벌림기(12)와 벌림로울러(13)(13')의 마찰력에 의해 벌린상태로 상승 이송하게 되는데, 이때 제품포장용 필림(3)이 인장력을 받게 되고 이 인장력에 의해 입설된 렉기어(4)(4')에 치합된 상하이송로울러(6)가 상승하게 되며, 원하는 길이 만큼 필림(3)이 벌림기(12)로부터 취출되면 타이머(15)에 의해 모터(9)를 정지시키게 되고 필림(3)의 인장력을 받아 상승하던 상하이송로울러(6)도 정지하게 된다.Referring to the operation and effects of the present invention configured as described above are as follows. When the motor 9 is operated by the timer 15, the film is rotated by the rotation of the lift rollers 10, 10 'and 11, 11' and the opener 13 and 13 '. It is conveyed upwardly by the frictional force of the opening rollers (13) and (13 '). At this time, the product packaging film (3) is subjected to a tensile force and is engaged with the rack gear (4) (4') which is placed by this tensioning force. The Shanghai Song Roller 6 is raised, and the film 3 is taken out of the opener 12 by the desired length to stop the motor 9 by the timer 15 and receives the tension force of the film 3. The rising Shanghai Song Roller (6) will also stop.

또 취출된 필림(3)은 핀거(16)에 의해 상부로 이송되어 제품포장용 필림(3) 하부가 히터에 의해 접합되고 히터 및 커터(도시하지 않았음)에 의해 접합후 절단하게 된다.The taken-out film 3 is transferred to the upper portion by the pinger 16 so that the lower portion of the product packaging film 3 is joined by a heater and cut after joining by a heater and a cutter (not shown).

필림이 절단되면 모터(1)가 작동하여 필름을 송출하게 되는데 자중에 의해 상하이송로울러 (6)가 다시 하강하게 되고 하한점에 이르게 되면 렉기어(4)의 하부에 부착된 리미트스위치(5)가 동작되어 모터(1)를 정지시켜 필림로울러(2)의 회전을 멈추게 하는 것이다. 그러므로 모터(9)에 부착된 타이머(15)의 조절로 원하는 만큼의 필림을 항상 일정하게 취출할 수 있도록 된 것이다.When the film is cut, the motor (1) is operated to feed the film. Due to its own weight, the Shanghai Song roller (6) is lowered again, and when the lower limit is reached, the limit switch (5) attached to the lower portion of the rake gear (4). Is operated to stop the motor (1) to stop the rotation of the film roller (2). Therefore, by adjusting the timer 15 attached to the motor 9, it is possible to constantly take out the film as much as desired.

상술한 바와 같이 본 발명은 일정량의 필림을 순차적으로 공급하므로서 원하는 만큼의 필림을 항상 일정하게 반복 공급하여 취출할 수 있도록 한 매우 유익한 발명인 것이다.As described above, the present invention is a very advantageous invention in which a certain amount of film can be sequentially supplied, and thus a desired amount of film can be constantly fed and repeatedly taken out.

Claims
