[Modes for carrying out the invention]

[0016] An embodiment of the rolled food manufacturing apparatus according to the present invention will be described in detail below with reference to the drawings. In the following description, when the directions of up, down, left, and right are indicated, they refer to the up, down, left, and right directions as viewed from the front as shown in the illustration.

[0017] <Description of the rolled food manufacturing machine> As shown in Figure 1, the rolled food manufacturing apparatus 1 has an endless belt conveyor 2 that is horizontally elongated in plan view and extends in the left-right direction, as shown in Figure 2. As shown in Figure 2, this endless belt conveyor 2 is installed with a pair of belts spaced apart in the vertical direction. Also as shown in Figure 2, a pair of rotating plates 3 that sandwich the endless belt conveyor 2 are provided at the left end 2a of this endless belt conveyor 2, and a vertically elongated rectangular rotating shaft 4 is attached so as to penetrate the axial direction of this pair of rotating plates 3. As shown in Figure 2, a first drive gear 5 is attached to the upper end of this rotating shaft 4, and this first drive gear 5 meshes with a second drive gear 6a that is attached to a first rotating mechanism 6. As shown in Figure 1, a rotating belt B1 is attached to this first rotating mechanism 6, and a second rotating mechanism 7 is attached to this rotating belt B1. Furthermore, as shown in Figure 1, a rotating belt B2 is attached to this second rotating mechanism 7, and a motor M is attached to this rotating belt B2. As a result, when the motor M is driven to rotate, the second rotating mechanism 7 rotates via the rotating belt B2, and further, the first rotating mechanism 6 rotates via the rotating belt B1. Thus, as the first rotating mechanism 6 rotates, the second drive gear 6a rotates, and the first drive gear 5, which is meshed with the second drive gear 6a, rotates. As a result, the rotating shaft 4 and the pair of rotating plates 3 rotate, and consequently, the endless belt conveyor 2 moves in the direction of arrow Y1 shown in Figure 2. As shown in Figure 1, a driven wheel 8 that rotates in conjunction with the movement of the endless belt conveyor 2 is provided on the right side of the diagram, and the endless belt conveyor 2 is stretched between this driven wheel 8 and the first drive gear 5. Therefore, the endless belt conveyor 2 moves in a loop between the driven wheel 8 and the first drive gear 5.

[0018] Thus, a vertically long rectangular roll food skin MK as shown in Fig. 5(a) baked by a baking drum (not shown) is conveyed to such an endless belt conveyor 2. Then, the roll food skin MK conveyed to the endless belt conveyor 2 is conveyed in the direction of arrow Y1 shown in Fig. 2 by the endless belt conveyor 2.

[0019] Incidentally, as shown in Fig. 3(a), a pair of guide portions 9 are provided on both the left and right end sides of the endless belt conveyor 2. As shown in Fig. 3(a), this guide portion 9 is formed in a half-divided shape and is provided upright so as to surround both the left and right ends of the endless belt conveyor 2. Then, as shown in Fig. 3(a), this guide portion 9 is provided on both the left and right end sides of the endless belt conveyor 2 so as to be in a flaring shape at the position on the left end portion 2a side of the endless belt conveyor 2. However, as it advances in the direction of arrow Y1 shown in Fig. 2, as shown in Fig. 3(b), it is provided on both the left and right end sides of the endless belt conveyor 2 so as to be in a narrowing shape. Further, as shown in Fig. 1, a tool supply mechanism 10 for supplying tools G such as raw meat and dried goods at regular intervals is arranged above the left end portion 2a side of the endless belt conveyor 2 of this guide portion 9. Since this tool supply mechanism 10 has a conventionally well-known structure, the description thereof is omitted.

[0020] Thus, when the skin MK for rolled food shown in Fig. 5(a) is conveyed in the direction of arrow Y1 shown in Fig. 2 by the endless belt conveyor 2, as shown in Fig. 5(b), the ingredients G are supplied at predetermined intervals by the ingredient supply mechanism 10. Further, when the skin MK for rolled food is conveyed to the endless belt conveyor 2, the left end MKa and the right end MKb (see Fig. 5(b)) of the skin MK for rolled food come into contact with the inner peripheral surface 9a of the guide portion 9 shown in Fig. 3. At this time, as the guide portion 9 advances in the direction of arrow Y1 shown in Fig. 2 and is in a narrowing shape as shown in Fig. 3(b), as the skin MK for rolled food is conveyed in the direction of arrow Y1 shown in Fig. 2, the left end MKa and the right end MKb of the skin MK for rolled food are bent inward (in the direction of the axis O shown in Fig. 5(b)) of the skin MK for rolled food by the pair of guide portions 9. As a result, the skin MK for rolled food assumes the state shown in Fig. 5(c). The angle at which the left end MKa and the right end MKb of the skin MK for rolled food are bent inward (in the direction of the axis O shown in Fig. 5(b)) of the skin MK for rolled food by the pair of guide portions 9 is 150° to 180°.

[0021] On the other hand, to the right of the driven wheel 8 shown in Figure 1, as shown in Figure 2, a pair of tension transfer rollers 11 are positioned at the left end MKc on the left end MKa side of the rolled food wrapper MK shown in Figure 5(c), and at the right end MKd on the right end MKb side of the rolled food wrapper MK shown in Figure 5(c). As shown in Figure 4, these tension transfer rollers 11 consist of an upper gear 11a located at the top of the diagram and a lower gear 11b located at the bottom of the diagram. As the upper gear 11a and the lower gear 11b rotate, the rolled food wrapper MK, which is in the state shown in Figure 5(c), is pulled between the upper gear 11a and the lower gear 11b, as shown in Figure 4. In this case, as shown in Figure 4, the outer surface 11a1 of the upper gear 11a is formed in an uneven shape, and the outer surface 11b1 of the lower gear 11b is also formed in an uneven shape. Therefore, as shown in Figure 4, when the rolled food wrapper MK is pulled in, the outer surface 11a1 of the upper gear 11a and the outer surface 11b1 of the lower gear 11b mesh together, and as shown in Figure 5(d), a continuously uneven winding line MKe is engraved on both ends of the left end MKc and the right end MKd.

[0022] On the other hand, as shown in Figure 4, a concave recess 11a2 is formed inward on a part of the outer circumferential surface 11a1 of the upper gear 11a, and a concave recess 11b2 is formed inward on a part of the outer circumferential surface 11b1 of the lower gear 11b. This reduces the situation in which the filling G supplied to the rolled food wrapper MK is crushed due to the meshing of the upper gear 11a and the lower gear 11b. In other words, as shown in Figure 4, the outer circumferential surface 11a1 of the upper gear 11a is formed in an uneven shape, and the outer circumferential surface 11b1 of the lower gear 11b is formed in an uneven shape, so when the outer circumferential surface 11a1 of the upper gear 11a and the outer circumferential surface 11b1 of the lower gear 11b mesh, the filling G supplied to the rolled food wrapper MK is crushed due to the meshing. Therefore, in this embodiment, since the ingredient supply mechanism 10 supplies the ingredient G at regular intervals, a recessed groove 11a2 and a recessed groove 11b2 are formed so that a part of the outer circumferential surface 11a1 of the upper gear 11a and a part of the outer circumferential surface 11b1 of the lower gear 11b do not mesh with each other. This reduces the situation in which the ingredient G supplied to the wrapper MK for rolled food is crushed due to the meshing of the upper gear 11a and the lower gear 11b.

[0023] Incidentally, as shown in Figure 2, a vertically elongated rectangular rotating shaft 12 is attached to the pair of tension transfer rollers 11 configured as described above, so as to penetrate the axial direction of the pair of tension transfer rollers 11. This rotating shaft 12 is attached to the upper gear 11a and the lower gear 11b, respectively, as shown in Figure 4.

[0024] As shown in Figure 1, a third rotation mechanism 13 and a fourth rotation mechanism 14 are attached to this rotating shaft 12, and these three mechanisms mesh together. The third rotation mechanism 13 is attached to the rotating shaft 12 on the upper gear 11a side, and the fourth rotation mechanism 14 is attached to the rotating shaft 12 on the lower gear 11b side.

[0025] On the other hand, as shown in Figure 1, a rotating belt B3 is attached to the fourth rotating mechanism 14, and this rotating belt B3 is attached to a gear Ma which is attached to the motor M. As a result, when the motor M is driven to rotate, the gear Ma rotates, and the fourth rotating mechanism 14 rotates via the rotating belt B3. Furthermore, the third rotating mechanism 13, which is meshed with the fourth rotating mechanism 14, also rotates. As a result, the rotating shaft 12 on the upper gear 11a side and the rotating shaft 12 on the lower gear 11b side rotate, respectively, so that the upper gear 11a and the lower gear 12a shown in Figure 4 rotate, respectively.

[0026] Incidentally, as shown in Figure 2, a vertically elongated rectangular cutting section 15 is provided on the right side of the tension transfer roller 11 in a plan view. When the rolled food wrapper MK in the state shown in Figure 5(d) is discharged from the tension transfer roller 11, this cutting section 15 cuts the rolled food wrapper MK at regular intervals, as shown in Figure 5(e). Note that a pair of these cutting sections 15 are provided in the vertical direction, and as this pair of cutting sections 15 rotates, the rolled food wrapper MK is cut at regular intervals, as shown in Figure 5(e).

[0027] On the other hand, each of these cutting sections 15 is fitted with a rotating shaft 16 as shown in Figure 2, and a fifth rotating mechanism 17 and a sixth rotating mechanism 18 are attached to these rotating shafts 16, respectively, as shown in Figure 1. The fifth rotating mechanism 17 and the sixth rotating mechanism 18 are meshed together.

[0028] On the other hand, as shown in Figure 1, the sixth rotating mechanism 18 is engaged with the seventh rotating mechanism 19, and a rotating belt B4 is attached to the seventh rotating mechanism 19. This rotating belt B4 is attached to the motor M. As a result, when the motor M is driven to rotate, the seventh rotating mechanism 19 rotates via the rotating belt B4. Furthermore, the sixth rotating mechanism 18, which is engaged with the seventh rotating mechanism 19, rotates, and the fifth rotating mechanism 17, which is engaged with the sixth rotating mechanism 18, also rotates. As a result, these rotating shafts 16 each rotate, and the pair of cutting sections 15 rotate.

[0029] Thus, as shown in Figure 5(e), the rolled food wrapper MK is cut S1 at regular intervals by the pair of cutting sections 15 described above, and small pieces MKA of the rolled food wrapper are formed.

[0030] Incidentally, these rolled food peel pieces MKA are transported to a net conveyor NC, which has a convex portion Ca formed on its surface, located to the right of the cutting portion 15 shown in Figure 2, as shown in Figure 6. This net conveyor NC is equipped with a belt conveyor C, as shown in Figure 6(a), and a mesh-like net NCa that can move up and down is positioned above the belt conveyor C. Therefore, when a rolled food peel piece MKA, as shown in Figure 5(e), is transported by the belt conveyor C in the direction of arrow Y1 shown in Figure 6(b), passing between the belt conveyor C and the net NCa, one end surface of the rolled food peel piece MKA (the upper end surface shown in Figure 5(e)) is rolled up by the net NCa, as the net NCa is movable up and down. In this process, the rolled food peel pieces MKA have continuously embossed winding lines MKe, as shown in Figure 5(e), and are wound up along these winding lines MKe, as shown in Figure 6(b) (see also Figure 5(f)). Furthermore, when the wound-up rolled food peel pieces MKA are further conveyed in the direction of arrow Y1 shown in Figure 6(b), they are wound up even further by the net NCa, as shown in Figure 6(c). In this process, the rolled food peel pieces MKA have continuously embossed winding lines MKe, as shown in Figure 5(f), and are wound up along these winding lines MKe in the direction of arrow Y2 shown in Figure 5(f).

[0031] Thus, by repeatedly performing this operation, the food wrapper MK for rolled foods is rolled up, and various types of rolled foods are manufactured as a result.

[0032] Therefore, according to this embodiment, the rolled food wrapper MK is folded by a pair of guide parts 9, and the folded rolled food wrapper MK is engraved with uneven winding lines MKe by the upper gear 11a and the lower gear 11b to facilitate winding, thus eliminating the need for the complex and large-scale equipment of the past.

[0033] Therefore, according to this embodiment, various types of rolled food products can be automatically manufactured easily and simply without the need for complex and large-scale equipment.

[0034] <Explanation of variations> It should be noted that the shapes and other features shown in this embodiment are merely examples, and various modifications and changes are possible within the scope of the gist of the present invention as described in the claims. For example, in this embodiment, an example is shown in which the uneven winding wire MKe is engraved by the upper gear 11a and the lower gear 11b, but it is not limited to this, and any method that can engrave the uneven winding wire is acceptable. However, it is preferable to engrave the uneven winding wire MKe by the upper gear 11a and the lower gear 11b as in this embodiment. This is because the configuration is simple and it is possible to accurately draw out the rolled food wrapper MK to a fixed length.

[0035] Furthermore, in this embodiment, an example is shown in which a concave recess 11a2 is formed on a part of the outer circumferential surface 11a1 of the upper gear 11a, and a concave recess 11b2 is formed on a part of the outer circumferential surface 11b1 of the lower gear 11b. However, the embodiment is not limited to this, and if unnecessary, the recess may not be formed. Moreover, the concave recess 11a2 may be formed only on the upper gear 11a, or the concave recess 11b2 may be formed only on the lower gear 11b.

[0036] Furthermore, in this embodiment, the shape of the food wrapper MK for rolled foods is exemplified as rectangular, but it is not limited to this, and any shape such as T-shaped or circular is acceptable.

[0037] Furthermore, in this embodiment, an example is shown in which a continuous embossed winding line MKe is engraved only on both ends of the folded rolled food wrapper MK. However, the invention is not limited to this, and the continuous embossed winding line MKe may be engraved on the entire folded rolled food wrapper MK, including both ends.

[0038] Furthermore, in this embodiment, although not shown, a sprayer capable of spraying adhesive onto the rolled food peel pieces MKA may be installed between the pair of cutting sections 15 and a belt conveyor (not shown) whose surface is formed in an uneven shape, in order to make it easier to roll up the rolled food peel pieces MKA.
