Conventionally, a Thomson blade was used to separate an object to be cut, such as a tray, into individual molded products from a sheet of molded products to be cut, which was formed by connecting a sheet of foamed synthetic resin in a grid pattern. After making continuous cuts, they were manually cut and separated.

[Problem that the invention seeks to solve]

However, after making discontinuous cuts in the molded product sheet to be cut with a Thomson blade, manually cutting and separating the molded products into individual molded products is not only extremely troublesome, but also has the problem of poor work efficiency. Ta.

In addition, the Thomson blade does not make discontinuous cuts,
Direct cutting could be considered, but in this case, a new problem arose: the individual molded products would fall apart after cutting and separation, and it would be troublesome to organize and package them afterwards.

The present invention has been made to solve these conventional problems, and it is possible to quickly cut individual pieces by stacking sheets of molded products to be cut, which are formed by connecting a large number of objects to be cut, such as trays, in a grid pattern. The purpose is to cut and separate molded products and to make packaging work after cutting and separation extremely easy.

[Means for solving problems]

In order to achieve such an object, the present invention provides a method for separating a sheet of molded products to be cut into individual molded products, which is formed by connecting objects to be cut, such as trays, in a grid pattern on the surface of a sheet made of foamed synthetic resin. In the separating device; the main body is provided with a base set to a size so as to place the molded product sheets to be cut in a stacked state;

We are trying to provide the equipment.

[Effect]

Using such a separation device, a sheet of molded products to be cut, which is formed by connecting objects to be cut, such as trays, in a square pattern on the surface of a sheet made of foamed synthetic resin, is cut and separated into individual molded products. When the square-shaped frame is erected and the abutment plate is positioned on the opposite side of the base of the square-shaped frame, it is possible to pass between the support parts provided on the upper and lower inner surfaces of the square-shaped frame. Stack sheets of molded products to be cut at a height, place them on the base either automatically or manually using appropriate transportation means, and drive the drive source of the pressing part that can move from one end of the base to the other end. Then, the pressing section presses the stacked sheets of molded products to be cut toward the other end of the base until the row of cut molded products at the tip contacts or comes close to the contact plate. When the row of molded products to be cut comes into contact with the contact plate or is close to the contact plate, the cylinder is driven from above to the row of molded products to be cut that is in front of the row of molded products to be cut at the tip of the stacked molded product sheets to be cut. At the very least, the other end of the base is pressed by the pressing part in front of it, and the row of molded products to be cut at the tip is driven from above and below by driving means such as cylinders through supporting parts provided on the upper and lower inner surfaces of the rectangle-shaped frame. It is moved up or down while being held, and the row of molded products to be cut at the tip is cut and separated from the others.

However, the contact plate is then moved out of the rotation range of the square frame, and the square frame, which is holding the row of molded products to be cut, is connected to an arm extending downward from the lower end of the frame. By driving the cylinder, the cylinder is rotated toward the side opposite to the base, and at the end of rotation, the clamping is released by the driving means such as the cylinder of the upper and lower support parts of the rectangle-shaped frame, and the cut pieces are separated. All you have to do is take out the molded product row.

When the molded products taken out in this way are still in a parallel state, they are further cut and separated by another separating device, and are then placed in a stacked state by a packaging device or by hand. The packaging is done according to the operation, and when the individual molded products are stacked, they are packaged as they are.

Furthermore, by returning the square-shaped frame and the contact plate to their original positions and repeating the above operations,
The sheets of molded products to be cut can be cut and separated into rows of molded products or individual molded products.
