Description

This invention relates to a food processing apparatus for automatically producing various types of rolled foods, such as spring rolls.

A conventional rolled food manufacturing apparatus is known, for example, the one described in Patent Document 1. This apparatus works by using the belt's running force to pull up the leading edge of the food wrapper as it contacts the belt surface after the filling is supplied, while simultaneously rotating the endless belt towards the upper surface of the conveyor. During this rotation, the food wrapper and filling are held between the endless belt and the conveyor, and the food wrapper is rapidly wound around the filling using the reverse running force between the endless belt and the conveyor to form a rolled food.

Below, an embodiment of the rolled food manufacturing apparatus according to the present invention will be specifically described 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.

<Explanation 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 conveyors 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.

Thus, the rolled food wrappers MK, which have been fired in a firing drum (not shown) as shown in Figure 5(a), are transported to the endless belt conveyor 2. The rolled food wrappers MK transported to the endless belt conveyor 2 are then carried by the endless belt conveyor 2 in the direction of arrow Y1 shown in Figure 2.

As shown in Figure 3(a), a pair of guide sections 9 are provided on both the left and right ends of the endless belt conveyor 2. These guide sections 9 are formed in a halved shape, as shown in Figure 3(a), and are positioned upright to surround both the left and right ends of the endless belt conveyor 2. Furthermore, as shown in Figure 3(a), the guide sections 9 are positioned on both the left and right ends of the endless belt conveyor 2 in a flared shape at the left end 2a, but as the direction of arrow Y1 shown in Figure 2 progresses, they become tapered at the end, as shown in Figure 3(b). Additionally, as shown in Figure 1, a bait supply mechanism 10 is positioned at the upper part of the guide section 9 on the left end 2a side of the endless belt conveyor 2, supplying bait G such as raw meat or dried goods at regular intervals. Note that this bait supply mechanism 10 has a conventionally known structure, so its explanation is omitted.

Thus, when the rolled food wrapper MK shown in Figure 5(a) is conveyed by the endless belt conveyor 2 in the direction of arrow Y1 shown in Figure 2, the ingredients G are supplied at predetermined intervals by the ingredient supply mechanism 10, as shown in Figure 5(b). Furthermore, when the rolled food wrapper MK is conveyed by the endless belt conveyor 2, the left end MKa and the right end MKb (see Figure 5(b)) of the rolled food wrapper MK come into contact with the inner circumferential surface 9a of the guide portion 9 shown in Figure 3. At this time, as the guide portion 9 moves in the direction of arrow Y1 shown in Figure 2, it becomes tapered, as shown in Figure 3(b). Therefore, as the rolled food wrapper MK is conveyed in the direction of arrow Y1 shown in Figure 2, the left end MKa and the right end MKb of the rolled food wrapper MK are bent inward (in the direction of axis O shown in Figure 5(b)) by the pair of guide portions 9. As a result, the rolled food wrapper MK will be in the state shown in Figure 5(c). The angle at which the left end MKa and the right end MKb of the rolled food wrapper MK are bent inward (in the direction of axis O shown in Figure 5(b)) by the pair of guide portions 9 is 150° to 180°.

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 illustration and a lower gear 11b located at the bottom of the illustration. 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 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 also formed in an uneven shape. Therefore, as shown in Figure 4, when the rolled food wrapper MK is retracted, the outer circumferential surface 11a1 of the upper gear 11a and the outer circumferential surface 11b1 of the lower gear 11b mesh together, resulting in a continuous uneven winding line MKe being engraved on both ends of the left end MKc and the right end MKd, as shown in Figure 5(d).

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. That is, 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 portion of the outer circumferential surface 11a1 of the upper gear 11a and a portion of the outer circumferential surface 11b1 of the lower gear 11b do not mesh with each other. This reduces the risk of the ingredient G supplied to the rolled food wrapper MK being crushed due to the meshing of the upper gear 11a and the lower gear 11b.

Incidentally, the pair of tension transfer rollers 11 configured as described above have a vertically elongated rectangular rotating shaft 12 attached to them, as shown in Figure 2, 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.

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 two 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.

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 gear Ma, which is attached to motor M. Therefore, when motor M is driven to rotate, 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, causing the upper gear 11a and lower gear 12a shown in Figure 4 to rotate.

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, as 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). A pair of these cutting sections 15 are provided in the vertical direction, and the rotation of this pair of cutting sections 15 causes the rolled food wrapper MK to be cut at regular intervals, as shown in Figure 5(e).

On the other hand, each of these cutting sections 15 is fitted with a rotating shaft 16, as shown in Figure 2. 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.

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. Therefore, 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 rotate, causing the pair of cutting sections 15 to rotate.

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, forming small pieces MKA of the rolled food wrapper.

Incidentally, these rolled food peel pieces MKA are transported to a net conveyor NC, which is located to the right of the cut section 15 shown in Figure 2, and has a protruding portion Ca formed on its surface, 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). Therefore, they are wound 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 transported in the direction of arrow Y1 shown in Figure 6(b), they are wound again by the net NCa, as shown in Figure 6(c). Note that, in this process, the rolled food peel pieces MKA have continuously embossed winding lines MKe, as shown in Figure 5(f). Therefore, they are wound along these winding lines MKe, in the direction of arrow Y2 shown in Figure 5(f).

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.

Therefore, according to this embodiment, the food wrapper MK is folded by a pair of guide sections 9, and the upper gear 11a and lower gear 11b simply engrave a raised winding line MKe onto both ends of the folded food wrapper MK to facilitate winding. Thus, complex and large-scale devices like those used in the past are unnecessary.

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.

<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 an uneven winding wire MKe is engraved using an upper gear 11a and a lower gear 11b, but it is not limited to this, and any method that can engrave an uneven winding wire is acceptable. However, it is preferable to engrave the uneven winding wire MKe using an upper gear 11a and a 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.

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; 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.

Furthermore, while a rectangular shape was used as an example for the food wrapper MK in this embodiment, it is not limited to this shape; any shape, such as T-shape or circular, is acceptable.

Furthermore, while this embodiment shows an example where the continuously embossed winding lines MKe are engraved only on both ends of the folded rolled food wrapper MK, it is not limited to this; the continuously embossed winding lines MKe may be engraved on the entire folded rolled food wrapper MK, including both ends.

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) with an uneven surface, in order to make it easier to roll up the rolled food peel pieces (MKA).
