Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a molding method for molding complex-shaped chewing gum from a plate-shaped gum sheet obtained by a conventional method.

(2) Prior art Chewing gum obtained by conventional methods has flexibility, and its shaping methods include rolling the chewing gum and cutting it into a predetermined shape using a cutter, and rolling and cutting a gum sheet. There are known methods in which the gum is formed into small pieces using a roller, etc., and a method in which rope-shaped gum is pressure-molded and formed into a predetermined shape.

However, in such known methods, only relatively simple shapes such as rectangles can be obtained.
In addition, as shown in Special Publication No. 50-2743,
There is also a method of sugar-coating gum chips, mixing them with other powders, pressurizing them with a rotary press, etc., and pressing the materials together to obtain a desired shape, but this method involves many steps and is not efficient. Moreover, there are many difficulties in manufacturing conditions in terms of preventing adhesion during the pressing process, and the shapes that can be obtained are limited to relatively simple shapes such as cylinders and quadrangular prisms.

Furthermore, as shown in Utility Model Publication No. 50-228, a gum with perforated lines attached to a rectangular gum was considered, but the overall shape of this gum was a strip-like one, and the present invention However, the problem is different from producing gum products with various desired shapes.

Furthermore, as seen in Japanese Utility Model Publication No. 54-16152, an appropriate uneven pattern is arranged on the upper surface of the inside of the hollow which has a sharp edge on the outer periphery, and the inner peripheral surface of the hollow has a bottom opening with a draft angle. However, in order to use such a confectionery press-cutting mold for processing sticky and solid products with a large proportion of powder, such as chewing gum, it is necessary to
Since a considerable amount of pressure is required, there is a problem in that a force is applied to the portion having a draft angle to push the press-cut die outward, causing easy breakage of the press-cut die. In addition, when the punching mold is released from the processed chewing gum, an impact must be applied, which is labor-intensive and unreasonable in terms of production. This tends to lead to problems and is not of practical use.

As described above, the conventional technology has the disadvantage that it is difficult to obtain chewing gum with a complex shape.

(3) Purpose of the Invention The present invention was invented in order to solve the above-mentioned drawbacks of the prior art, and provides a molding method that can easily mold chewing gum into complex shapes such as those of vehicles and animals. It's about getting.

(4) Structure and Effects The present invention provides the following features: (a) A cutting blade of a punching die having a cutting edge portion formed in a predetermined shape is caused to cut at high speed on the surface of a gum sheet on a base that is conveyed at a constant speed. (b) At an internal position of the cutting blade of the punching die, forming a pressing-type patterned blade that forms an uneven shape on the chewing gum that is cut into a predetermined shape by the cutting blade while the cutting blade is acting on the chewing gum. (c) disposing an elastic material on the contact surface side of the gum sheet around the cutting blade and the pattern blade; and (d) making the pattern blade holder separate from the cutting blade support. This chewing gum molding method involves molding chewing gum into a desired shape from a gum sheet consisting of four main parts, which are constructed independently and an elastic body is interposed on the back side of the above-mentioned holder, so it is extremely complex and precise. This led to the creation of chewing gum with a specific shape.

That is, the elastic material is placed on the contact surface side of the gum sheet around the cutting blade and the patterned blade. In other words, the cutting blade and the patterned blade are formed in a shape that is embedded in the elastic material. The gum sheet and the chewing gum molded from it can be smoothly separated from the cutting blade and pattern blade, and the chewing gum has a precision molding effect.In addition, since the gum sheet deforms very little, the next molding can be carried out on the traces of the previous molding. Since it can be done in close proximity, it is possible to reduce the amount of chips produced in the past. Furthermore, by configuring the pattern blade holder separately from the cutting blade support and attaching an elastic body to the back surface of the cutting blade support to change its elastic modulus, subtle irregularities can be created on the chewing gum. can be formed.

(5) Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1-1 are plan views of chewing gum obtained by the method of the present invention, and a molding apparatus as shown in FIG. 2 is used to obtain such molded products. In FIG. 2, 1 is a base that moves at a constant speed, and an elastic sheet 1 is placed on the base 1.
The gum sheet 2 is placed through a. On the other hand, above the base 1, a support 3 is arranged parallel to the base 1, and a cutting blade 4 is fixedly installed in a hole formed in the support 3. As the cutting blade 4, a blade formed in a desired shape as shown in FIG. 1 is selected. The cutting edge may be a single-edged type or a double-edged type as shown in FIG. Inside the cutting blade 4, a patterned blade 6 formed of convex portions for forming cuts, grooves, and recesses on the surface of the chewing gum 5 is disposed, and the patterned blade 6 does not necessarily have to be a blade. , sometimes just a protrusion. This patterned blade 6 is implanted in a holding body 7. This holder 7 is disposed so as to be movable in the depth direction of the cutting blade 4, and an elastic body 8 is provided on the back of the holder 7. On the outside and inside of the cutting blade 4, resilient materials 9a and 9b made of hard sponge or the like are provided on the support 3.
and is attached to the holding body 7. Bullet material 9a
is formed at almost the same height as the cutting blade 4, and the other resilient material 9b is formed at almost the same height as the patterned blade 6. As a result, the cutting blade 4 and the patterned blade 6 are It is embedded in the resilient materials 9a and 9b.

3a is a back plate that is integrated with the holder 3 that supports the elastic body 8, and by changing the elastic force of the elastic body 8, the patterning can be varied. In order to mold chewing gum using the molding device configured as described above, as shown in FIG. In the pattern blade 4
The cutting/separating action is performed by moving the side or the base 1 side at high speed as shown by the arrow and applying pressure. This cutting and the forming of the pattern following the cutting are done instantaneously, but during this process, the gum sheet 2
is firmly held by the elastic materials 9a, 9b and the base 1 while compressing the elastic materials 9a, 9b, and at the same time the cutting blade 4 and the pattern blade 6 act on the gum sheet 2. After the cutting blade 4 reaches the bottom dead center, it is pulled out from the gum sheet 2, but at this time, the explosive materials 9a and 9b are
This prevents the gum from adhering to the cutting blade 4, which prevents the molded gum from deforming and sharpens the shape of the molded product. 4 and pattern blade 6 can be smoothly separated.

After the chewing gum is formed, the base 1 is moved laterally again to prepare for the next cutting, but the chewing gum 5
is sharply cut off from the gum sheet 2 and there is little deformation, so it is possible to cut very close to the previous cutting mark, and good results can be obtained in terms of yield.
