Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an automatic molding method for wrapped products and a material feeding device used for the method.

<Conventional technology and its problems> Conventionally, automatic wrapping machines used for forming manju buns, daifuku mochi, etc. have two paths: one for sending out the filling for the inner filling, and one for sending out the dough for the outer layer. , are installed separately and independently in terms of their internal and external positions, and the two materials merge, so to speak, only at the exits of both passages.

Therefore, the mechanism of the wrapping machine is extremely complicated.
Not only when large-scale production of the same product is carried out, but also when small- to medium-volume production of a wide variety of products is carried out, frequent cleaning work is required due to changes in the product. It is difficult to carry out the cleaning simply and efficiently, and also because the above-mentioned materials tend to adhere and remain in a clogged state, it is impossible to obtain a complete cleaning effect.

In addition, since both the inner and outer materials are distributed separately, it is not possible to stably form the desired complete filled product from the beginning of the machine's operation, and during test runs, This results in a large amount of wasted material for the outer skin. and,
In order to prevent this, it is necessary to introduce both materials at the right time according to their feeding action, which is extremely troublesome.

Moreover, since the feeding action of the material is performed by an extrusion screw, etc., forced pulling force (kneading force) and kneading force are repeatedly applied to the dough material of the outer cover. As a result, there is a problem in that the outer skin is damaged and the commercial value (particularly the appearance and taste) of the wrapped product is deteriorated.

<Means for Solving the Problems> With the purpose of solving the above problems, the present invention provides an automatic forming method for the wrapped product, which uses a plurality of feeders that are driven to rotate around a horizontal axis. The overall funnel-shaped hopper is divided by rollers, and the peripheral speed of the feed roller is changed to gradually increase as it goes to the lower exit of the hopper, and the desired package is delivered into the hopper. A large lump of bean paste is introduced, and the coarse lump is forcibly fed out from the lower outlet of the hopper in the form of a continuous bar by a feed roller. As a wrapped product,
It is characterized by being wrapped into a nearly spherical shape and divided into regular size pieces.

In addition, as a material feeding device for automatic molding of the stuffed products, a plurality of feeding rollers that are driven to rotate around a horizontal axis are arranged in parallel in several layers stacked above and below, thereby creating an overall funnel-shaped structure. In addition to forming sections as a hopper, the circumferential speed of the feed roller is set to gradually increase as it goes to the lower exit of the hopper, and the large lumps of the target packed product fed into the hopper are The first feature is that it is configured so that it can be forcibly fed out as a continuous rod-like form from the lower outlet of the hopper, and furthermore, a falling guide tube is connected in communication with the lower outlet of the hopper as described above. The guide tube is divided into sections by a plurality of other feed rollers that are all driven to rotate around the horizontal axis in the same direction as the feed roller, and are installed in parallel in several stacked layers above and below. The second aspect of the present invention is that the large lumps of the target stuffed product put into the hopper are forcibly sent out from the hopper through the falling guide tube and from the lower outlet of the guide tube in the form of a continuous rod. This is the characteristic of

<Example> Hereinafter, the details of the present invention will be explained based on the drawings. In FIGS. 1 and 2, which schematically show the automatic molding machine for the filled product, H is a hopper that receives the material M, A plurality of feed rollers 11 (total 20 in the example shown), which are driven to rotate around a horizontal axis in the direction of arrow P, are installed in parallel in a stacked state in several stages above and below, thereby partitioning into an overall funnel shape. It is formed.

That is, for example, a set of five feed rollers 11 are pivotally supported in a stacked horizontal structure in several parallel stages to form unit wall surfaces for partitioning the hopper H, and such unit wall surfaces are arranged in pairs facing each other to form a total of four rollers. Each hopper H is defined as having a rectangular opening in plan view and tapering smoothly toward the bottom.

In that case, in the partitioned form shown in FIG. 2, a plurality of feed rollers 11 having the same length are used, each of which is supported in a so-called cantilever state by a bearing 12 only at one end, and such feed rollers 11 are The above-mentioned unit wall surface consisting of a set of five rollers 11 is made to alternately intersect as if it were reminiscent of a swastika shape to form a hopper H, but instead of this, as shown in the modified example of FIG. A plurality of feed rollers 11 are used, which are longer as they are in the lower position and shorter as they are in the lower position, and each of them is supported in a so-called double-supported state by a pair of common bearings 12 at both ends. It is also possible to divide a unit wall consisting of a set of five feed rollers 11 into a hopper H by intersecting each other so that the bearings 12 are located at the corners.

13 is a motor for rotationally driving each feed roller 11, S1 is a large-diameter upper entrance of the hopper H, and S
Reference numeral 2 denotes a lower outlet having a small diameter, but its opening shape is not limited to the rectangular shape in plan view as shown in the figure. The feed roller 11 may have a concave or convex surface, for example, and it is possible to form the opening shape from a plurality of rollers. In any case, the funnel shape of the hopper H provides the material M with smooth spreadability during its feeding action.

A plurality of feed rollers 11 in the above laminated state
are all driven to rotate in the direction of the arrow P shown in the figure so that they can feed the material M received in the hopper H downward, and are also kept in a parallel state to prevent frictional contact between adjacent ones. Arranged. However, it goes without saying that the mutual gap is set to be extremely small so that the material M does not leak out.

Moreover, as is clear from FIG. 1, the thickness (diameter dimension) of the plurality of feed rollers 11 increases as they move downward, such that the ones at the upper stage are thinner and the ones at the lower stage are thicker. The feed roller 1 is changed so that it gradually becomes thicker.
1 is rotated at a uniform speed,
The circumferential speed of the roller 11 is configured to increase in stages as it moves toward the lower outlet S2 of the hopper H. Therefore, the material M in the hopper H is forced to be sent downward by the feed roller 11.

In the case of the present invention, the input material M is a large coarse lump B of the target stuffed product A. In other words, a large lump B is hand-prepared in which the filling of the inner member M1 is temporarily wrapped in the viscous dough of the outer shell M2, like a snowman, and this is directly poured into the hopper H from the upper entrance S1. . Therefore, the large rough lump B comes into direct frictional contact with the surface of the feed roller 11 on the fabric surface of the outer skin M2, and together with the overall funnel shape of the hopper H, the large lump B is smoothly rolled by the roller 11. While being spread, it becomes a continuous semi-finished filling product C in the form of a rod and is sent downward together with the inner member M1. It goes without saying that the size of the coarse lump B corresponds to the unit processing amount per one time.

When changing the peripheral speed of the feed roller 11,
In FIG. 1, the thickness of the rollers 11 is varied, but instead, as shown in the modified example of FIG. The rotational speed may be set so that the rotation speed of the lower position is sequentially faster than that of the upper position.

Further, reference numeral 14 designates a pair of left and right rotating cutters facing the lower outlet S2 of the hopper H, which are rotated in the same direction and at the same speed by a driving motor 15 via a transmission body 16. It is becoming more and more common. 17 is each cutter 1
It is a spiral blade provided on the circumferential surface of 4, and both upper and lower surfaces for generating this are set as guide step surfaces 18 and 19 for receiving the material M. Furthermore, the spiral blades 17 are opposed to each other in such a manner that their heights are the same between the two cutters 14, so that the semi-finished filling product C in the form of a rod sent out from the lower outlet S2 of the hopper H is processed. In order to complete the desired small-sized wrapped product A, it is possible to automatically wrap it into a substantially spherical shape and cut it into regular size pieces.

Reference numeral 20 denotes a material receiving tray that takes part in the enveloping and dividing action, and is placed directly below the two rotary cutters 14 facing the opposing gap. This is attached to the upper end of the column 21 which can be raised and lowered, and its raising and lowering action allows the gap with the guide stepped surface 19 to be adjusted in size. This serves to preliminarily change the size of the intended spherical shape of the stuffed product A. or,
The tray 20 is also adapted to be rotated in a direction opposite to the cutter 14.

Then, the semi-finished stuffed stuffed product C fed out from the hopper H in a continuous rod-like shape is wrapped into a substantially spherical shape by a pair of rotating cutters while its lower end is supported by the receiving tray 20, and at the same time, it is cut into a fixed size. The product is cut into small pieces to be completed into a small packaged product A, which is then transferred onto a conveyor 23 by an ejector 22 and sent out of the machine. It should be noted that a mechanism other than that shown in the drawings may be used as the mechanism for carrying out the above-mentioned enveloping/separating action.

Next, FIGS. 5 and 6 show various modified embodiments of the material feeding device corresponding to FIGS.
A drop guide tube G is installed in communication with this.

That is, the drop guide cylinder G is a hollow cylinder with an opening diameter substantially equal to that of the lower outlet S2 of the hopper H, and also rotates around the horizontal axis in the same direction as the hopper defining roller 11. The partitions are formed by arranging a plurality of other driven feed rollers 24 in parallel with the hopper defining roller 11 in a stacked state of several layers above and below. S3 and S4 indicate the upper inlet and lower outlet of the drop guiding tube G.

In the basic embodiment shown in FIGS. 1 and 2, the hopper H
When a bar-shaped semi-finished stuffed product C is sent out from the lower outlet S2 of
Where there is a risk of the product being subjected to a reaction that expands in the left and right directions, the falling guide cylinder G is installed in order to effectively prevent this and to provide a restraining effect on the wrapped product C, so to speak. . From that meaning,
The opening diameter of the guide tube G is the lower outlet S2 of the hopper H.
is determined to be substantially the same as that of

In that case, a plurality of the feed rollers 24 for defining the drop guide tube G may have the same thickness, and the feed rollers 24 for defining the hopper may have the same thickness.
Similarly to 1, it is possible to make the lower position thicker than the upper position and change the circumferential speed. Furthermore, if the thickness is the same, the circumferential speed may or may not be changed. In any case, according to both of the modified embodiments in which the drop guide tube G is installed, the large coarse lump B thrown into the hopper H is once sent from the hopper H into the drop guide tube G by the feed roller 11. Then, by the defining feed roller 24 of the guide tube G, it is sent out from the lower outlet S4 of the guide tube G as a continuous semi-finished packaged product C in the form of a rod, and then it is wrapped into a substantially spherical shape. At the same time, it is cut into pieces of fixed size, and the desired small-sized wrapped product A is completed.

The other configurations and functions of the modified embodiment described above are substantially the same as those of the basic embodiment shown in FIGS. 1 and 2, so the corresponding symbols with those in FIGS. 1 and 2 are written in FIGS. The detailed explanation will be omitted.

<Effects of the Invention> As described above, in the automatic forming method for the wrapped product A according to the present invention, the overall funnel is The hopper H of the mold is divided into sections, and the circumferential speed of the roller 11 is changed to gradually increase as it goes to the lower outlet S2 of the hopper H, and the large-sized stuffed product A is transferred into the hopper H. The coarse lump B is introduced, and the large coarse lump B is conveyed from the lower outlet S2 of the hopper H by the feed roller 11.
It is forcibly fed out as a continuous rod-shaped product, and then wrapped into an approximately spherical shape and cut into pieces to a fixed size so that a semi-finished wrapped product C in a bar-like shape becomes a small-sized wrapped product A. Therefore, there is an effect that the problems of the prior art mentioned at the beginning can be solved.

In other words, by simply feeding the large lump B into the hopper H without distinguishing between the inner member M1 and the outer shell M2, the desired small, almost spherical filled product A can be formed automatically and reliably and efficiently. It is extremely easy to work with. In addition, since the large rough lump B of the intended stuffed product A is fed in, a large amount of material M is not wasted during test operation of the molding machine, and furthermore, only the inner material M1 is used as an extrusion screw, etc. Since there is no problem of adhesion to the material, cleaning can be done easily, and therefore it is particularly useful for small- to medium-volume production of a wide variety of products that requires frequent material changes.

Further, the material M is forcibly sent out as a semi-finished filling product C in the form of a rod from the hopper H or the falling guide cylinder G, and the outer skin M2 comes into frictional contact with the circular surfaces of the rotating feed rollers 11 and 24. Therefore, it is not repeatedly subjected to the kneading force and kneading force as in extrusion screws, and is not actively subjected to it. Therefore, damage to the outer skin M2 is effectively prevented, and the wrapped product A is rich in commercial value. This means that it will be possible to manufacture
