Description

[Detailed description of the invention] This invention relates to a cutting device for foamed resin, which is capable of cutting the curved shapes of various articles and heat-cutting the foamed resin along the shape. When forming a packaging material for a product, the foamed resin of the packaging material can be heat-cut at the same time as the shape of the product is molded.

Conventionally, in order to form packaging materials, consignment materials, etc. made of synthetic resin foam etc. for various products to suit the overall or partial shape of each product, it has been necessary to measure each product and mold it. etc., and are formed by molding or by heat cutting from block-shaped or plate-shaped foamed resin after measurement, for shapes that are extremely difficult to measure, such as articles with many curved parts, etc. In addition, the larger the shape of the article, the more troublesome it is to accurately measure it, and it is difficult to form it into a desired shape.

Therefore, in this invention, we have solved the above-mentioned drawbacks and inconveniences of the conventional technology, and created a device that can perform heat cutting at the same time as making a mold.The structure is such that a fixed frame with a shape that can be placed on it has a movable structure. a first slider is provided, a moving frame that moves together with the first slider is connected to the first slider, and the moving frame is further equipped with a second slider that is movable in a direction perpendicular to the first slider; A cutter holding member is attached to the second slider, and a rod-shaped mold-cutting cutter having one end as a molding cutter and the other end as a heat cutter is attached to the holding member so as to be movable up and down with respect to the fixed frame mounting surface. The present invention is characterized in that the shape of the object to be molded can be heat-cut from the foamed resin using a heat cutter while the object to be molded is brought into contact with the object to be molded.

Next, embodiments of this invention will be illustrated below with reference to the drawings.

1 and 1' are parallel fixed frames assembled into a shape that can be placed, 2 and 2' are fixed frames 1,
1' is a slide groove formed, 3, 3' is a first slider equipped to be able to move in the A-A' direction along the slide grooves 2, 2', and 4, 4' are first sliders. This is a locking member that is activated when it is desired to prevent movement of the parts 3 and 3'.

Reference numeral 5 denotes a moving frame connected to the first sliders 3 and 3', which has a frame shape as shown in FIG. As shown in FIG.
The slide groove 6, 6' or 6'' is equipped with a second slider 7, 7' or 7'' which can move in the direction B-B' perpendicular to the first slider 3, 3'. 8, 8' or 8'' indicates the locking member of the second slider.

Further, 9 is a holding member for a heat cutter, which is attached to the second slider 7, 7' or 7'', and 10 is a mold-making cutter, which is attached to the mounting surface of the fixed frame 1, 1'. The cutter 1 is provided so as to be movable in the vertical direction of C'.
0 has a rod shape and one end (lower side in the figure)
is formed as a mold material 11, and the other end (upper side in the figure) is formed as a heat cutter 12, and there is usually a heat insulating part 1 between the two materials.
It is preferable to form 3. 14 is a lock member for the cutter.

Note that the shape of the cutter 10 can be implemented in various ways as shown in the figure, and the mold cutter 11 is equipped with a roller 15 at the tip to facilitate guide of the shape.
It is also possible to form a roller 16 on the heat cutter 12 (see FIG. 6). Furthermore, within the holding member 9 for the heat cutter, as shown in FIG. 4, it is necessary that the parts 17 and 18 that hold the mold-making cutter 10 can freely move up and down.
Various known sliding mechanisms such as an interior slider can be employed.

When using the above-mentioned cutting device to simultaneously heat cut the foamed resin while making a mold, if the A-A' direction is the horizontal direction, the other B-
The B' direction is the vertical direction, the horizontal direction is the sliding grooves 2, 2' of the fixed frames 1, 1' and the first sliders 3, 3', and the vertical direction is the sliding grooves 6 of the movable frame 5 or 5'. , 6' or 6'' and the second slider 7, 7' or 7''. If the horizontal direction of the A-A' direction is the reference direction, the second slider 7, 7', 7'', moving the moving frame 5 or 5' and moving the holding member 9 in the lateral direction, aligning the shape of the object to be molded with the mold material 11, which is one end of the rod-shaped cutter 10, while cutting the other end. Using the heat cutter 12, the foamed resin Y installed on the upper side can be heat-cut into the same shape as the object to be molded. 9
When the position of the cutter 10 is shifted vertically in the B-B' direction and the cutter 10 is moved in the A-A' direction as before,
It can perform molding and heat cutting at the same time at a position shifted in the vertical direction (for example, see Fig. 7), and can easily respond to both vertical and horizontal irregularities, and can also heat cut a large area. This can be done on foamed resin in the same shape as the material to be molded, which is extremely convenient, and allows packaging materials and other shapes made of foamed resin to be provided in a state that is compatible with the shape of the material to be molded, which is the material to be packaged.

In addition, since the foamed resin Y to be cut is light, it is preferable that the lower side of the mold cutting cutter 10 is formed with the mold cutting material 11 and the upper side formed with the heat cutter 12, but it is also possible to carry out the process by installing it in the opposite direction. It is possible.

As described above, this devised device can easily heat-cut even complex curved shapes, and in particular, the holding member is equipped with a bar-shaped mold-cutting cutter with one end formed as a molding material and the other end as a heat cutter. Because it is equipped with a mold, it is possible to accurately heat-cut the shape of the object to be molded from the foamed resin, even if it has a complex shape with irregular uneven surfaces, and is suitable for heat-cutting that is adapted to the shape lines of various articles. This is an extremely convenient device for providing packaging materials and the like that correspond to the shape of the article.
