Abstract

The present invention provides a lamination device for a corrugated cardboard box, capable of maximizing productivity and improving quality of a corrugated cardboard box by improving a structure of a corrugated cardboard feeder device. A transfer unit forming the feeder device is individually installed in an upper guide and a lower guide of the corrugated cardboard lamination device. A hanging unit is installed on both sides of a support forming the transfer unit to supply outer paper and corrugated cardboard to a feeding roller. The hanging unit enters a hanging unit guiding groove formed on both sides of a guiding roller. The support is installed in a sliding member reciprocating by being installed in a screw forming a ball screw to reciprocate between the guiding roller and the feeding roller. One side of the screw is connected to a driven shaft installed in a bevel gear box. A time belt pulley is installed in a driving shaft for driving the driven shaft and is operated by a servo motor by being connected by a time belt. According to the present invention, a rotation force of the servo motor is changed into a linear motion by the ball screw in order for the support to reciprocate to rapidly and accurately laminate the outer paper and the corrugated cardboard. Therefore, the lamination device for a corrugated cardboard box can improve the quality and maximize productivity. The support forming the transfer unit is operated by the servo motor and the ball screw, so the durability and accuracy are remarkably improved. Therefore, the lamination device for a corrugated cardboard box can maintain the accuracy even if the lamination device is used for a long time.

Description

급지장치가 개선된 골판지 박스용 합지기{Conjunction for corrugated cardboard box that feeder improves acquaintance}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a corrugated cardboard box feeder improves acquaintance,

본 발명은 급지장치가 골판지 박스용 합지기에 관한 것으로서, 더욱 상세하게는 골판지 박스를 제조하는 과정에서 골판지에 외피지를 합지하기 위하여 골판지와 외피지를 한장씩 합지용 롤러에 공급할 때, 좀 더 신속하고 정확하게 공급할 수 있도록 급지장치가 개선된 골판지 박스용 골판지 합지기에 관한 것이다.The present invention relates to a paper feeder for a corrugated cardboard box, and more particularly, to a paper feeder for corrugated cardboard box, more particularly, The present invention relates to a corrugated cardboard frame assembly for a corrugated cardboard box.

주지하는 바와 같이 박스용 골판지 박스를 구성하는 박스용 골판지는 표면에 그림과 상호 등을 인쇄할 수 없거나 매우 어렵기 때문에 그림과 상호 등이 인쇄된 외피지를 골판지의 표면에 접착하여 박스용 골판지가 제조된다.As it is known, since the corrugated board for box constituting the corrugated box for box can not print pictures or mutual information on the surface or is very difficult, the corrugated cardboard for box is adhered to the surface of corrugated cardboard do.

상기와 같이 박스용 골판지의 표면에 그림과 상호 등이 인쇄된 외피지를 접착하기 위한 골판지 박스용 합지기의 종래 구성을 살펴보면, 골판지 박스용 합지기의 상부에 외피지를 공급하기 위한 외피지 급지장치와, 하부에 골판지를 공급하기 위한 골판지 급지장치가 구성되어 있고, 상기 외피지 급지장치와 골판지 급지장치의 일측에 외피지와 골판지가 만나는 지점에 접착제 도포용 풀통과 그 앞쪽에 합지용 롤러가 설치되어 있다.The corrugated cardboard box assembly according to the present invention comprises a corrugated cardboard box assembly for corrugated cardboard boxes and a corrugated cardboard box assembly for corrugated cardboard boxes, And a corrugated cardboard feeder for feeding corrugated cardboard at a lower portion thereof is provided at one side of the outer paper feeder and the corrugated cardboard paper feeder at a point where the corrugated paperboard and the outer paper meet, have.

그런데, 상기한 외피지 급지장치와 골판지 급지장치를 구성하는 걸림구가 체인에 소정의 간격으로 고정되어 있고, 상기 걸림구가 고정된 체인이 체인기어에 의해서 구동되도록 구성되어 있기 때문에 속도가 매우 느려질 수밖에 없어 골판지 박스를 생산하는 능력이 크게 떨어지는 단점이 있다.However, since the above-described external-fatigue feeding device and the corrugated cardboard feeder are fixed at predetermined intervals on the chain, and the chain to which the above-mentioned retention hole is fixed is driven by the chain gear, the speed is very slow There is a drawback that the ability to produce corrugated cardboard boxes is greatly reduced.

또한, 걸림구가 체인 및 체인기어에 의해서 구동되면 소음과 진동이 많이 발생하여 작업환경이 나쁘게 되고, 특히 체인구동은 정확성이 떨어지기 때문에 외피지와 골판지가 정확한 지점에 공급되고 접착되지 않는 관계로 골판지 박스 불량이 많이 발생할 뿐만 아니라 품질이 떨어지는 단점이 있다.In addition, when the stopper is driven by the chain and the chain gear, noise and vibration are generated and the working environment is deteriorated. Especially, since the chain drive is not accurate, the outer oil and the corrugated cardboard are supplied to the correct spot and not bonded There are disadvantages that corrugated board boxes are not only defective but also quality is low.

상기한 단점을 해결하기 위하여 수시로 체인 상태를 점검하고 수리를 해야하는 관계로 골판지 박스용 골판지 합지기를 가동을 중지해야하기 때문에 그에 따른 생산성도 크게 떨어지는 등, 종래 골판지 박스용 골판지 합지기는 구조적으로 많은 문제가 있다.In order to solve the above-mentioned disadvantages, since the chain condition must be checked and repaired from time to time, the corrugated cardboard joiner for corrugated cardboard boxes must be shut down, resulting in a significant decrease in productivity. have.
