2. Description of the Related Art The present applicant has previously filed Japanese Patent Application Laid-Open No. 62-1481.
In No. 97, a large number of molded products to be cut, such as trays, are formed on a single thermoplastic foam synthetic resin sheet by forming discontinuous cuts between the individual molded products to form a grid-like structure. Disclosed is an apparatus for separating foamed synthetic resin molded products by stacking cut molded product sheets and separating them into individual molded products. In this separating device, the molded product sheets to be cut are stacked, and the stack of the molded product sheets to be cut is stacked one line before the stacked cutting product line at the tip in the direction orthogonal to the transfer direction by the transfer means. By pressing one side surface of the row of molded products to be cut by the pressing means, this is pressed against the side plate provided on the machine body on the other side of the side surface, and as a result, the tip end is stacked in a state of being sandwiched from both sides. By pressing the other side surface of the row of molded products to be cut by the separating means, the cutting-corresponding portion between the row of molded articles stacked at the tip and the row of stacked stacked molded articles one row before the row is cut in the thickness direction. By relatively shifting to, the connecting portion between the cuts is cut, and the row of to-be-cut to-be-cut products to be stacked at this tip is separated from the other to-be-cut row of to-be-cut products.

[0003]

Such a separation device has the following problems.
Sheets of molded products to be cut can be stacked and mechanically separated into individual molded products, which enables post-processing in accordance with the molding cycle of molded products such as trays, which is industrially possible. Has received great attention. However, a large load is placed on the separation because it simultaneously cuts all the connecting parts between the cut-corresponding cuts between the row of molded products to be stacked at the tip and the row of molded products to be stacked one row before this. I need power. Also, if the load required for separation is not sufficiently large, the continuous skin layer on the surface of the molded product sheet to be cut at the connecting portion between the cuts of the corresponding cut portion will stretch, and the surface of the molded product will not be reliably cut. In some cases, the peeling phenomenon of the skin layer may appear. For this reason, it is conceivable to shorten the connecting portion between the cuts provided in the molded product sheet to be cut, but when this cut is provided by punching, the peripheral edge is trimmed at the same time, and then the corners of the molded product are chamfered. Therefore, when considering a series of processes in which the corresponding parts are punched out, further stacked and transferred to the separating device, this processing state where the connected part between the cuts may be cut during the process and the molded product may separate. Is not always preferable.

In order to solve these problems, the device for separating foamed synthetic resin molded articles according to the present invention is designed to reduce the load force required for the separation as much as possible and to separate the skin layer from the surface of the molded article. The purpose is to reduce the appearance of phenomena.

It can be separated into a row of molded articles to be cut or molded articles, and after-treatment that is compatible with the molding cycle of molded articles such as trays is possible, and since there is no need to use a blade in particular, maintenance is easy, Moreover, because it has a take-out means,
These can be taken out easily, and the taken-out products can be stacked to facilitate the packaging work.

In addition, the stacked cut-out molded product sheet or the cut-out molded product line is placed on a mounting table, and the stacked cut-out molded product line at the tip in the direction orthogonal to the transfer direction by these transfer means or When separating a molded product to be cut from other stacked molded product rows or a molded product to be cut, forcibly insert a plate-shaped separating member into the cut-corresponding portion between these stacked products. Then, spread the connecting part between the cuts in this cut corresponding part through this cut,
Since the cutting is sequentially performed from the side closer to the separation member over time, the load force required for the separation can be made as small as possible. Further, since the cutting force can be effectively applied to the end of the connecting portion between the cuts through the end of the cut,
The peeling phenomenon of the skin layer is less likely to appear on the surface of the molded product.
