There are openings 58, 58 through which the pivots 56, 56 passing through the above-mentioned points 50 (having the axis extending in the front-rear direction as viewed in FIG. 1, that is, the direction perpendicular to the plane of the drawing as the central axis) are passed. Side wall 5
2, 54 are slightly separated from the outer diameter of the cylindrical member 18 of the content extrusion device 20, and the pivots 56, 56 are fixed to diametrically opposite positions of the outer surface of the cylindrical member 18. . Side wall
54 has a right extending portion 60 (as viewed in FIG. 1) with a pivot hole 62 at its right end. And
A cylindrical member is provided in the pivot hole 62 by a driving device described later.
A lower end of a connecting link 66 pivotally attached to a movable barrel 64 that is vertically moved around 18 is pivotally attached, and the blade 40 is pivoted about a pivot shaft 56 by vertically moving the movable barrel,
The above-mentioned contents passing parts 40 ', 42', 44 ', 46' are opened and closed.
The opening 70 provided in the side wall is for passing the blades 44 and 46 set so as to be orthogonal to the blade 40.

The blade 42 has substantially the same form as the blade 40, but the radius of the bottom surface centered on the point 50 is slightly smaller than the radius of the upper side surface centered on the same point of the blade 40, and the side wall 66 thereof. The spacing between the outer surfaces of 68 is the side wall 52 of the blade 40,
The distance between the inner surfaces of 54 is made smaller, so that the blade 42 can be set inside the blade 40 as shown in FIG. 1, and the pivot hole 71 for connecting to the movable cylinder 64 is It is provided on the left side opposite to the blade 40. A hole 72 in the upper center of the side wall 66 is adapted to receive the same pivot 56 as the blade 40, and thus the movable barrel.
With the vertical movement of 64, the blade 42 is pivoted around the pivot 56 in the direction opposite to the blade 40. The opening 74 provided in the side walls 66 and 68 is formed by the blade 40.
Like the openings 70 in the side walls of the blades, they are for the blades 44, 46 to pass through.

The blade 44 is superposed on the blade 42 as shown in FIG. 1, and is moved in a direction perpendicular to the blade 42 (a front-back direction as viewed in FIG. 1, that is, a direction perpendicular to the plane of the drawing). As shown in FIGS. 6A to 6C, the blade 44 has a vertical side wall at the center of its both side edges (left and right edges in FIG. 1).
78, 80, and a pivot (not shown) having an axis extending horizontally in the left and right directions (see FIG. 1) passing through the point 50 at the upper ends of both side walls (not shown). ) Is formed in the cylindrical member 18, and the pivots inserted in the holes 82 are attached to the left and right side walls (as viewed in FIG. 1) of the cylindrical member 18. Further, the left side wall 80 is provided with an extension portion 84 extending rearward (in the direction of the back surface of the paper of FIG. 1), and at the end thereof, the connecting link 66 pivotally attached to the movable cylinder 64 and the connecting link 66. A pivot hole 86 for pivotally attaching the lower end of a similar connecting link (not shown) is provided, and the movable cylinder 64 is provided.
The vertical movement of the blade causes the blade 44 to pivot about the pivot axis received in the hole 82.

The blade 46 has almost the same shape as the blade 44, but has a small size so that it can be placed on the blade 44, and a connecting link similar to the connecting link 66 connected to the movable cylinder 64. The difference is that a pivot hole 84 for pivotally attaching the lower end of the blade (not shown) is provided in an extension portion 86 extending to the side opposite to the blade 44 (front side in the plane of FIG. 1). The holes 88 provided on both side walls of the blade 46 are holes of the blade 44.
It is adapted to receive the same axis as the axis received by 82, and thus the movable barrel 64 moves up and down to move in a direction perpendicular to the blades 40 and 42 and in a direction opposite to the blade 44. .

As can be seen from the above, the blades 40, 42, 44 and 46 are movable cylinders 64.
With the vertical movement of the same, they are simultaneously moved in the directions separated by an angular interval of about 90 ° and moved between the closed position and the open position.

It has been mentioned above that the blades 32, 34, 36, 38 of the first cutting device 22 are moved in the horizontal plane at a distance of about 90 ° from each other, but these blades are also similar to the blades of the second cutting device. A connecting link 96 as shown in FIG. 3 is attached to a movable cylinder 94 provided around a column 92 of the double ball pedestal 90 (FIG. 1).
(The blade 32 and its connecting link 96 are only shown in FIG. 3) and the movable cylinder 94 moves up and down to perform the above-mentioned movement.

Next, a drive system for driving the above-mentioned device will be described with reference to FIG.

In the figure, reference numeral 100 denotes a cam wheel, which is driven at a constant speed in the arrow direction by a motor (not shown). A first bell crank 102, a second bell crank 104 and a driven wheel 106 are engaged with the cam wheel 100.

The first bell crank 102 swings about its pivot 108 by a cam contour curved surface (not shown) on the surface of a cam ring (not shown), and the movable barrel of the second cutting device 24 connected to one end thereof.
It is designed to move up and down 64.

The second bell crank 104 also swings around its pivot 110 by a cam contour curved surface (not shown) of the cam wheel 100, which is different from the above, and the movable cylinder of the first cutting device 22 connected to one end thereof. 94
It is designed to move up and down.

The driven wheel 106 has, as shown in FIG. 8, six rotary wheels 112 provided on the lower surface thereof at equal intervals (60 °), and is provided in a cam groove 114 provided in the cam wheel 100 shown as an exploded view. When the cam wheel 100 is engaged, the cam wheel 100 is rotated by 120 ° for each rotation. The driven wheel 106 has a rotation transmission shaft 116 (FIG. 3) fixed to the center of the upper surface thereof, and a sprocket 120 provided at the upper end thereof. The sprocket 120 is connected by an endless chain 122 to a sprocket 122 fixed to the shaft upper end of the screw of the content material supply pump 28.

As can be seen from the above, the first and second cutting devices 22, 24 and the pump 28 are driven by one drive source via the cam wheel 100.

9A to 9C show the displacement of each blade of the first and second cutting devices and the rotation of the screw of the pump 28 (vertical axis) with respect to the rotation angle of the cam wheel 100 (horizontal axis). First, the displacement of the blade of the second cutting device will be described.

The blade of the second cutting device is shown in the "open position" from FIG. 10B as shown in FIG. 10A with all of the contents threaded portions 40 ', 42', 44 ', 46' aligned and overlapping, as described above. By moving in each direction, the overlapping of the contents passing parts is reduced and the opening A is made smaller, so that the contents passing parts 40 ', 42', 44 ', 4'as shown in FIG. 10C.
It is in a "closed position" where there is no 6'overlap,
On the contrary, it is moved to the "open position".
In FIG. 9B, the blades 40, 42, 44, 46 are in the “closed position” when the rotation angle of the cam wheel 100 is between 60 ° and 150 °, and the opening A is generated as the rotation angle increases from 150 °. It becomes the "open position" at ° and further becomes the "closed position" when it reaches the angular position of 60 ° through 360 ° (0 °). The displacement of the blade up to 150 ° -270 ° -360 ° (0 °) -60 ° is approximately a cosine curve.

The rotation of the screw of the pump 28, which pushes out the contents of the material through the opening A, causes the displacement as shown in FIG. 9A. That is, when the rotation angle of the cam wheel is 60 ° to 150 °, the rotation is zero, and when it is 150 ° to 270 °, the rotation speed increases to 270 °.
It rotates at a reduced speed in the range of 360 ° (0 °) to 60 °. This speed change corresponds to an increase or decrease in the area of the opening A. The relationship between the feeding of the internal material by the rotation of the screw and the displacement of the blades 40, 42, 44, 46 of the second cutting device is such that the material passed through the opening A is in a state close to a sphere. To be done. The relationship between the feed amount (speed) of the pump and the opening / closing area of the valve is completely synchronized, and the increase / decrease change is a theoretical curve (for example, a modified sin curve).

FIG. 9C shows the displacement amount of the blades 32, 34, 36, 38 of the first cutting device. The blades 40, 42, 44, 46 are in the open position even when the blades are in the closed position from 60 ° to 150 °. It is said that the back side (upper side) of the extruded and separated contents should also be wrapped with the outer skin, and at the end of 165 °, it should be in the closed position and the double-ball food consisting of the inner and outer skin should be separated. It has become.

Effects of the Invention The device according to the present invention is configured as described above,
A vertical plane including the first and second horizontal axes, which are the pivot axes of the four blades, by properly controlling the four blades set at intervals of 90 degrees with respect to each other in relation to the content supply amount by the pump. The inner cross section can be circular, and the shape of the entire molded content can be made to be quite spherical. Therefore, it is possible to achieve the intended purpose described above, especially in the case of a product having a thin outer skin, it is possible to make the product close to a spherical shape as a whole due to the influence of the spherical contents, It is useful.

Incidentally, in the above-mentioned embodiment, the contents passing portions 40 ', 42', 4
Although 4'and 46 'are shown as circular openings, it is not limited thereto, and, for example, when they are in the intermediate position between the open position and the closed position, the contents of those threading portions forming the openings A are It is also possible to make notches having only arcuate edges.
