【Example】

The present invention will be explained based on one embodiment. The inner packaging material 1 is supplied to the inside through the material supply port 4 communicating with the side wall of the inner cylinder 3 by the material supply device 2. It is supplied between the cylinder 3 and the center cylinder 5. In addition, the outer skin material 6 is a material provided on the side wall of the outer cylinder 7. It is supplied between the outer cylinder 7 and the inner cylinder 4 through the supply port 8 . These outer cylinder 7, inner cylinder 3, and center cylinder 5 are arranged concentrically, and the lower end 9 of the outer cylinder is at the lowest point. The lower end 10 of the inner cylinder is provided inside the bell, and the lower end 10 of the inner cylinder and the lower end 9 of the outer cylinder are provided with a tape. It is in a flat state. The center cylinder 5 is located at the center of the inner cylinder 4, and the lower end 11 of the center cylinder is the lower end 10 of the inner cylinder in FIG. It is located at the middle position of the lower end 9 of the outer cylinder, but depending on the nature of the product being manufactured, it may be placed at the same position as the lower end 10 of the inner cylinder. It may be located at the same level as or higher than that, or at the same level as or lower than the lower end 9 of the outer cylinder. Ru. In this way, the annular gap formed by the lower end 9 of the outer cylinder, the lower end 10 of the inner cylinder, and the lower end 11 of the central cylinder The raw material is discharged, and a concentric rod-shaped dough is formed such that the outer skin material 6 covers the inner packaging material 1. be done.

[0007] The cutting device 12 cuts the rod-shaped dough into a predetermined size, and FIG. A square piece 13 having a thickness a constitutes the main part of the cutting device 12, and 14 and 15 are square pieces. The sliding surface between the piece 13 and the adjacent square pieces 13' and 13" is shown. The sliding surface 14 has an upper surface 141 , a middle surface 142 , and a lower surface 143 on the entire length of one side of the square piece 13 . form a convex surface. Furthermore, the sliding surface 15 has an upper surface 151, a middle surface 152, and a lower surface 153 to form a concave surface. The convex sliding surface 14 of this one square piece 13 and the concave sliding surface 15' of the adjacent square piece 13' are engage. As shown in Figure 3, three or more rectangular pieces of the same shape are assembled, and the center of this assembly 16 is A box 17 is formed in the box, and the sliding movement of these opens and closes the box. In this embodiment, the square piece 13 will be explained using six assemblies 16, but the number is limited to six. The enclosure can be formed by assembling three or more pieces, and is practical. Generally speaking, 4 to 12 pieces is appropriate. The enclosure 17 is surrounded by a sliding surface 14, which allows the rod-shaped material to pass through this enclosure. This is the surface that presses against the fabric, and its cross section forms a convex shape in the axial direction of this rod-shaped fabric. 18 in Figure 5 is a continuous rod-shaped dough that is fed through the box 17; The surface forms a concentric circle with the inner wrapping material 1 and the outer covering material 6, and the solid material 32 is supplied to the center of the inner wrapping material 6. has been done. 5 to 7, the square piece 13 is slid in the direction of the arrow by a drive mechanism not shown, Box 17 shows the open/closed state. The rectangular piece 13 slides in the direction of the arrow, the box 17 becomes smaller, and eventually it becomes smaller as shown in FIG. Each tangent line 1421 gathers in one place and the box disappears, and at this time the box is surrounded by tangent lines 1411 and 1431. dents 191 are formed on the top and bottom, but as the sliding progresses further, the dents 191 disappear as shown in Figure 7. The intersection points 1412 (top surface) and 1432 (bottom surface) come together to form only a flat surface. If you move the square piece in the opposite direction of the arrow, box 17 will appear.

[0008] Next, to explain the solid material supply section, the center cylinder 5 is inserted into the inner cylinder 3 from above the inner cylinder 3. It is inserted toward the lower end 7 of the outer cylinder through the axis of the outer cylinder. Above the center cylinder 5 is an air cylinder 21, a rod 22, which is attached to the tip of the rod 22. A pushing mechanism consisting of a pusher 23 is provided, which controls the operation of the air cylinder 21. As the rod 22 moves in and out, the pusher 23 moves up and down in the center cylinder 5. When the base 25 is attached to the frame 24, the hole 51 made in the base is connected to the center cylinder 5. I try to make it fit. A rotating plate 26 is rotatably fitted into the base 25. Holes 27 are provided in the rotary plate 26 at predetermined intervals, and as the rotary plate 26 rotates, the holes 27 are connected to the base holes 51. The holes 27 are made to match each other. Further, cams 28 are fixedly provided on the upper surface of the rotary plate 26 in correspondence with the number of holes. An air cylinder 29 is provided in the center of the base 25, and the rod 30 of the air cylinder 29 protrude alternately from both ends of the cylinder 29 toward the cam 28. FIG. 13 is a top view of the solid material supply section. ' is attached, and each time the rod 30 protrudes front and back alternately, the roller 31 or 31' is attached. The rotary plate 26 rotates one pitch at a time in contact with the cam 28, and the hole 27 sequentially aligns with the center cylinder 5. It is now possible to

[0009] A solid object 32 such as a chestnut is placed in the hole 27 manually or by a placing device (not shown). When the air cylinder 29 is actuated, the solid material 32 is moved every pitch of the rotary plate 26. It is then thrown into the center cylinder 5. At this time, the one-pitch rotation of the rotating plate 26 and the one-time movement of the air cylinders 21 and 29 are the same. It is performed in synchronization with one cycle (one cutting) of the cutting device 12. The operational flow of the embodiment of the present invention is shown below. Timer receives signal from cutting device ↓ Timer sends activation signal to air cylinder 29 ↓ Air cylinder 29 operates ↓ Air cylinder 29 stops ↓ Air cylinder 21 operates downward. ↓ Air cylinder 21 operates to rise. ↓ end

[Effect]

To explain the operation of the present invention, the continuous rod-shaped dough 18 into which the solid material 32 is inserted from the solid material supply section is cut by a cutting device that operates in synchronization with the insertion operation of the solid material 32. A complete enveloping cut is performed without exposing the inner enveloping material. When cutting the rod-shaped dough 18, the pusher 23 continuously supplies the solid material 32 as shown in FIG. When the thickness a ₁ of the generatrix contact surface of the convex sliding surface 14 of the square piece 13 contacts the rod-shaped fabric and the outer skin is guided in the direction of the axis of the rod while keeping a ₁ unchanged, the thickness within the inner packaging material remains unchanged. Solid objects that are lined up next to each other can also be separated and moved up and down to perform enveloping and cutting.

[0011]Furthermore, according to this configuration, unlike the products produced by the conventional wrapping cutting device shown in FIGS. 11 and 12, the cut surface may have flower pattern-like folds or solid matter may be exposed. This is not the case, and the effect of cutting smoothly is created. To make it easier to understand, the action and effect are as shown in FIG _. 8, taking as an example a rod-shaped fabric made of an inner wrapping material and an outer skin material. As shown in FIG _. It moves to the center of the enclosure 17, and the outer cover 6 moves to the center, and the inner wrapping material 1 flows in the direction of the arrow m. When the tangent lines 1421 come together, the moved fabric is separated above and below the tangent line 1421 to become upper and lower fabrics, which can completely cover the inner wrapping material 1. At this time, when the upper surface 141 and the lower surface 143 forming the non-acute convex sliding surface 14 enter the axis of the cloth 18, the upper surface 141 and the lower surface 143 move the cloth by a predetermined amount to the center and also move the cloth from the circumferential direction. Since the constriction formed by pressing has a reduced surface area, it can be cut without thinning the outer skin 6 or exposing the inner packaging material 1. In addition, since the concave sliding surface 15' engages with the convex sliding surface 14, the annular surface surrounded by the upper surfaces 14 1 and 143 around the enclosure 17 has no grooves or steps and will not pinch the fabric. Smooth enveloping cuts are made, and there are no flower-like folds on the cut surface. Furthermore, even if scraps of fabric adhere to the sliding surface 15 when cutting the fabric, the tangents 1411, 1421, 1431, which are the tangents of the convex sliding surface and the concave sliding surface, are in sliding contact 141, 14 2, 143 surface can be traced and the residue removed, and the fabric will not stick when cutting the wrapping. In the conventional enveloping cutting device shown in Figs. 11 and 12, steps 50 are formed on both the upper and lower sides at the abutting part of the sliding surface, so the thin part of the outer skin of the flower-shaped pleats that occur due to this when cutting the fabric. There are cases where solid matter is exposed, but this does not occur in the present invention.

0012 A new effect of this invention is that the box is closed when and after the tangent lines 1421 gather. Since this is a two-step closure of a set of intersection points 1412 that occur immediately, it is difficult to cut a highly elastic fabric. Even if the fabric cannot be completely cut by cutting along the tangent line 1421, the The fabric can be completely separated into upper and lower parts by cutting at the intersection point 1412. In addition, in the process from 1421 to 1412, the contact surface forced the outer skin material 6 to the center (top). can be induced to In addition to the convex sliding surface 14 and the concave sliding surface 15, the square piece in this embodiment has a housing 52. A missing portion 55 may be provided at the joint between the convex sliding surface 14 and the outer sliding surface 54 that slides on the inner surface 53 of the 5 to 7 and 8A to D. The motion is as if a depression 191 disappears. As another example, the square piece shown in FIGS. 4 and 9 has an arcuate sliding surface. In this case as well, the same effect as described above was confirmed.

[0013] Also, since the material supply port is provided on the side wall of the inner cylinder, the structure is much more significant than the conventional example shown in Figure 14. This simplifies the process, making disassembly and assembly easy. Because the distance has been significantly shortened, the delivery pressure in the supply path is reduced, resulting in a low discharge volume. There is no longer any sign of it dropping.

[0014]

[Effect of the idea]

As explained above, the present invention prevents wrapping and cutting even when solid materials are continuously fed. When wrapping, it is possible to securely encapsulate solid objects one by one, and it is possible to wrap relatively large solid objects. It became possible to mold products with shapes. Furthermore, since the cut surface of the envelope is smooth, There is no need for the post-process of smoothing the surface of the product, which has flower-like pleats as in the past. This made it possible to significantly streamline production.
