Description

本発明は、液晶表示装置等の表示パネルやカラーフィルタ基板あるいは加工前のガラス基板等の板状体の、輸送するために緩衝材である合紙を介して複数枚多段積重された積層体の状態から、合紙を取り除く合紙除去装置、ならびに、この合紙除去装置を用いて合紙を取り除いて板状体を取り出す開梱装置及び開梱方法に関する。   The present invention relates to a laminated body in which a plurality of plate-like bodies such as a liquid crystal display device or the like, a color filter substrate, or a glass substrate before processing are stacked in a plurality of stages via interleaving paper as a buffer material for transportation. The present invention relates to a slip sheet removing device that removes slip sheets, and an unpacking device and a unpacking method for removing slip sheets using this slip sheet removing device and taking out a plate-like body.

液晶表示装置等の表示パネル等は、一般に、相互に対向して配置されたカラーフィルタ基板と素子基板との間に液晶を封入して構成される。このようなカラーフィルタ基板や素子基板、あるいはそのベースとしての(素)ガラス基板や電極等が形成された状態のガラス基板の半製品を輸送する場合には、従来、ガラス基板をその側縁部で保持する収納ボックス内に入れ多段積載させて輸送する。   A display panel or the like such as a liquid crystal display device is generally configured by enclosing liquid crystal between a color filter substrate and an element substrate that are arranged to face each other. When transporting such a color filter substrate or element substrate, or a semi-finished glass substrate on which a (raw) glass substrate or electrode as a base is formed, the glass substrate is conventionally used as a side edge portion. In the storage box held by, transport in multiple stages.

近年、各種の表示パネルには、0.7mm以下の薄さのガラス基板が使用されるようになっている。また、特に、大型液晶テレビの普及に伴い、使用されるガラス基板は、最近では第6世代(1500mm×1800mm)、第8世代(2160mm×2460mm)、あるいは第10世代(2850mm×3050mm)と呼ばれる様に年々大型化している。   In recent years, a glass substrate having a thickness of 0.7 mm or less has been used for various display panels. In particular, with the widespread use of large LCD TVs, the glass substrates used are recently called the 6th generation (1500 mm × 1800 mm), the 8th generation (2160 mm × 2460 mm), or the 10th generation (2850 mm × 3050 mm). The size is increasing year by year.

このような大型で薄いガラス基板は撓み易いため、ガラス基板収納ボックス内に複数枚のガラス基板が収納されていると、輸送時に各ガラス基板が撓んで隣接するガラス基板同士が接触することによって破損するおそれがある。このために、ガラス基板収納ボックス内のガラス基板同士が接触しないように、100mm以上の間隔をあけて保持する必要があり、更に基板取り出し用吸着パッドの挿入間隔も必要なために、ガラス基板の収納枚数を増やせない問題があり、輸送効率が悪く、輸送費用が高くなる問題があった。   Since such a large and thin glass substrate is easily bent, if a plurality of glass substrates are stored in the glass substrate storage box, each glass substrate is bent at the time of transportation and damaged due to contact between adjacent glass substrates. There is a risk. For this purpose, it is necessary to hold the glass substrates in the glass substrate storage box at intervals of 100 mm or more so that the glass substrates do not come into contact with each other. There is a problem that the number of stored sheets cannot be increased, and there is a problem that transportation efficiency is poor and transportation cost is high.

そこで、上記したガラス基板の大型化にともない、より搬送効率が高く、かつ安定に基板を輸送する方式として、合紙と基板を交互に積み重ねて積層体とする方法が知られている。この方式において、積層体を開梱する際には、合紙と基板を分離する機能を備えた、適切な開梱装置を用いる必要がある。   Therefore, as the glass substrate is increased in size, as a method of transporting the substrate with higher transport efficiency and stability, a method of stacking interleaving papers and substrates alternately to form a laminate is known. In this method, when unpacking the laminated body, it is necessary to use an appropriate unpacking device having a function of separating the slip sheet and the substrate.

合紙を除去し、積層体を開梱する方法として、特許文献1には、合紙を介してパネルが積層状に積み重ねられたパネル積層体から合紙を取り除くに際し、最上層のパネルの上面に重ね合わされる合紙に吸着パッドを吸着させ、次いでその合紙に吸着させた吸着パッドをその合紙の紙面内側方向に移動させてその合紙を歪ませ、その合紙と最上層のパネルとの密着状態を解除する合紙除去装置で、吸着パッドにはシリンダおよび真空ポンプが配管を介してつなげられており、合紙を真空吸着した状態で、積層体から除去する技術が開示されている。また、特許文献2には、アームと、アームの先端部に係合されたヘッドと、そのヘッドが板状体に接近もしくは離れる方向に移動させる移動機構を備え、このヘッドが合紙を狭持する機構を有する合紙除去装置が開示されている。狭持機構部を合紙に押し当てた状態で、狭持部を摺動させて合紙を挟み込み、積層体から除去する。   As a method for removing the interleaf and unpacking the laminated body, Patent Document 1 discloses that when removing the interleaf from the panel laminated body in which the panels are stacked in a laminated manner via the interleaving paper, Adsorb the suction pad to the interleaving paper superimposed on the paper, and then move the suction pad adsorbed to the interleaving paper toward the inner side of the interleaving paper to distort the interleaving paper. A slip sheet removing device that releases a close contact state with a cylinder, and a vacuum pump is connected to the suction pad through a pipe, and a technique for removing the slip sheet from the laminated body in a vacuum sucked state is disclosed. Yes. Further, Patent Document 2 includes an arm, a head engaged with the tip of the arm, and a moving mechanism that moves the head in a direction approaching or leaving the plate-like body. A slip sheet removing apparatus having a mechanism for performing the above is disclosed. In a state where the holding mechanism portion is pressed against the interleaving paper, the sandwiching portion is slid to sandwich the interleaving paper and removed from the laminate.

しかしながら、前記特許文献1の、合紙を吸着する方法では、合紙として不織布や織物のように、隙間が多く容易に空気が透過するものを用いた場合には、吸着できないため積層体より除去できない問題がある。また、前記特許文献2の、合紙を狭持する方法では、挟み込みを行う際に、狭持部を積層体に押し当てる必要があるため基板に傷がつく可能性がある問題があった。   However, in the method of adsorbing interleaving paper in Patent Document 1, when interleaving paper having a large gap and easily allowing air to pass through is used as the interleaving paper, it cannot be adsorbed and removed from the laminate. There is a problem that cannot be done. Further, in the method of sandwiching the slip sheet of Patent Document 2, it is necessary to press the sandwiching part against the laminated body when sandwiching, and there is a problem that the substrate may be damaged.
