製品を１個１個に分離させる分離装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for separating a synthetic resin molded product, and more particularly, to a sheet formed in a state where a number of products are partially connected in a grid pattern. The present invention relates to a separating device for separating the above products from a synthetic resin molded article into individual products.
＜従来の技術＞ 従来、上記シート状合成樹脂成形品を個々の製品に分

としての１個の製品が、上下に多数積み重ねられた状態
を合成樹脂成形品列（又は成形品列）という。However, performing this task manually was inefficient and inefficient. Therefore, a separation device has been provided which can separate the sheet-like synthetic resin molded articles at a time in a state of being stacked in large numbers. In the following description, a state in which one product as a finished product is vertically stacked in a large number is referred to as a synthetic resin molded product row (or a molded product row).

うになっている。As disclosed in, for example, Japanese Patent Application Laid-Open No. Sho 62-148196, the conventional separating device includes a conveying device that conveys a large number of sheet-shaped synthetic resin molded products in a stacked state, and a front end in a conveying direction of the conveying device. And a rectangular frame provided on the side and capable of simultaneously holding a plurality of rows of synthetic resin molded products arranged in a horizontal direction from above and below. The square frame is provided with a support portion for holding the row of molded products, and the lower end thereof is pivotally supported by a single support shaft orthogonal to the transport direction. It falls down while holding the resin molded product.

形後、数分以内に製品へ分離するような場合、上記合成
樹脂成形品が未だ余熱のある状態で完全に冷却していな
いので、殊更潰れ易いという問題点がある。<Problems to be Solved by the Invention> However, in the separation device, since the support portion in the square-shaped frame sandwiches the synthetic resin molded product row from above and below, a strong force for shearing is applied to the molded product. There is a drawback that the yield is lowered due to deformation or crushing of several upper sheets. In particular, when the sheet-like synthetic resin molded product is separated into products within a few minutes after molding, the synthetic resin molded product is not yet completely cooled in a state where there is residual heat, so that it is particularly easily crushed. There is.
また、載置台上に供給された成形品列を分離する押圧
板も、積み重なった成形品列の上方または下方の一方側
から押圧するので、このときにも成形品がさらに変形し
たりつぶれてしまったりするという欠点もある。Also, the pressing plate for separating the row of molded articles supplied on the mounting table is pressed from above or below one of the stacked rows of molded articles, so that the molded articles are further deformed or crushed. There is also the disadvantage of rolling.

り返して合成樹脂成形品列を分離搬送するので、１回の
分離作業にかなりの時間を要し、作業効率を向上させる
ことができないため、コストアップの要因になっている
という問題点がある。Furthermore, since the above-mentioned square frame repeatedly separates and conveys the synthetic resin molded product line by repeating the upright state and the laid-down state, it takes a considerable amount of time for one separation operation, and the operation efficiency cannot be improved. However, there is a problem that the cost is increased.
