The forming apparatus disclosed in Patent Documents 1 and 2 is an apparatus that folds and forms the outer skin material (dough) placed on the pair of enveloping plywood plates (plate materials) by folding the pair of enveloping plywood plates (plate materials). However, if the fabric piece is placed on the wrapping plate at a position shifted from the desired position, there is a problem in that the fabric piece cannot be folded at the desired folding position. Furthermore, although it is possible to mold kashiwamochi into a predetermined shape, there is a problem in that the shape cannot be changed arbitrarily.

The molding device disclosed in Patent Document 3 describes that a pair of sealing members adjust the position of the outer skin material placed on the receiving member, but the sealing members do not touch the edge of the outer skin material. Since the folded food product is pushed from both sides, the outer skin material may be bent or otherwise deformed, making it impossible to reliably adjust the position, and the sealing portions may not be aligned, resulting in a problem in which the appearance of the folded food product is spoiled.
In addition, since the pushing member that supplies the inner material to the outer skin material is equipped with a push bar, there is a problem that the placement position of the inner material cannot be adjusted with respect to the lowered position of the edge of the outer skin material that is folded in half. be. For example, when pushing the pushing member (pushing bar) deeply into the receiving member, the sealed portion of the outer skin material becomes wider (longer), causing the problem that the inner material is biased toward the bottom of the food. On the other hand, when the pushing member is pushed in shallowly, the sealed portion of the outer skin material becomes narrower (shorter), resulting in a problem that a substantially semicircular appearance such as a cream bun cannot be formed. In other words, it is not possible to adjust the range (length) of the sealed portion of the outer skin material formed around the inner material.

The conventional forming apparatus disclosed in Patent Document 4 does not have a device to correct the positional deviation of the outer skin material transferred onto the placement surface of the packaging unit, so there is a problem that the sealed parts of the folded food are not aligned. There is. In addition, a protrusion is provided on the pressing surface of the pressing member, and after placing the outer covering material on the wrapping unit, the pressing member presses both ends of the outer covering material against the wrapping unit, and creases are formed at both ends of the outer covering material. A groove is formed. However, since the protrusion is integrally formed on the pressing member, it is possible to form a sweet bread in a predetermined shape, but there is a problem in that the shape cannot be changed arbitrarily.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a folded food product forming apparatus that can align an outer skin material to a required folding position with respect to a wrapping unit. Furthermore, the present invention provides a folded food forming device that can adjust the range (length) of the sealed part of the outer skin material formed around the inner material, and is capable of forming various folded foods with different appearances.

Each support shaft 25A (25AW, 25AZ) is rotatably supported by each bearing 25B (25BW, 25BZ). Further, as will be described later, the bearing 25B is provided so as to be able to reciprocate in the X direction.

The drive mechanism 25 includes two sets each of slide mechanisms 26 (26A, 26B), link mechanisms 27 (27A, 27B), and clutch mechanisms 28 (28A, 28B), which are arranged so as to be point symmetrical in plan view. has been done. The slide mechanism 26, the link mechanism 27, and the clutch mechanism 28 are connected to each other. , 24Z) to approach and leave.

One slide mechanism 26A shown on the front side in the Y direction in FIG. 3 includes a swing arm 26C, a shaft 26D, a block 26E, and a drive shaft 26G. The drive shaft 26G is detachably connected to one drive shaft 7C that stands up from the base portion 7B of the base 7A. The swing arm 26C is connected to the drive shaft 26G and is provided to be able to swing horizontally. The shaft 26D is supported slidably in the X direction on the upper surface of the base housing 13A, is connected to the swing arm 26C, and reciprocates. The block 26E is integrally fixed to the shaft 26D, and a groove 26F is vertically carved on the side surface of the shaft 26D opposite to the mounting surface.
The other slide mechanism 26B is configured similarly to the slide mechanism 26A, and is connected to the other drive shaft 7C.

The arm 27C is integrally attached to the shaft end of a shaft 27D that is rotatably supported by the clutch mechanism 28A, and has a cam follower 27G on one end. The cam follower 27G is slidably fitted into the groove 26F of the block 26E. One end of a link plate 27F is connected to the other end of the arm 27C. An arm 27E attached to a support shaft 25AW of each wrapping plate 24W is connected to the other end and the intermediate position of the link plate 27F.

In the shaft 27J of the link mechanism 27B, the base end of the arm 27K is integrally attached to one shaft end shown on the front side. One end of a link plate 27L is connected to the other end of the arm 27K. An arm 27M attached to a support shaft 25AZ of each packaging plate 24Z is connected to the other end and the intermediate position of the link plate 27L. The back side link mechanism 27A and the link mechanism 27B are configured point-symmetrically with the front side link mechanism 27B and the link mechanism 27A, respectively, and are connected to the wrapping plate 24W and the wrapping plate 24Z.

Clutch mechanisms 28A and 28B support shaft 27D of link mechanism 27A and shaft 27J of link mechanism 27B, respectively. The clutch mechanisms 28A and 28B are mechanisms that respectively switch between a state in which the shafts 27D and 27J are fixed and rotation is stopped, and a state in which the shafts 27D and 27J are released and rotation is possible. The clutch mechanism 28 includes an engaging member operated by a drive means such as an actuator, but since this is a known technique, detailed explanation will be omitted.

Further, the clutch mechanism 28A is connected to the bearing 25BW by a joint 28C, and is provided so as to be able to reciprocate in the X direction together with the wrapping plate 24W. The other clutch mechanism 28B has the same configuration as the clutch mechanism 28A, is connected to the bearing 25BZ by a joint 28D, and is provided so as to be able to reciprocate in the X direction together with the wrapping plate 24Z. Therefore, when the slide mechanism 26 reciprocates, in a state where the shafts 27D and 27J are fixed to the clutch mechanism 28 and the link mechanism 27 cannot swing, the pair of covering plates 24 (24W, 24Z) move as the clutch mechanism 28 moves. ) reciprocate in the horizontal direction as they approach and move away from each other. In addition, when the shafts 27D and 27J are not fixed to the clutch mechanism 28 and the link mechanism 27 is swingable, the pair of wrapping plates 24 (24W, 24Z) swing as the link mechanism 27 reciprocates.

The extension device 18 includes a pair of extension members 18A in the width direction, an actuator 18B that raises and lowers the extension members 18A, and a frame mechanism 18C that connects the extension members 18A and the actuator 18B.

The plate-shaped extension member 18A is arranged between the positioning members 16A on both sides of the presser member 15B, and moves up and down guided by a vertical groove 15S provided in the vertical direction on the outer periphery of the presser member 15B. The lower end of the extension member 18A is rounded on the inside (on the side of the holding member 15B), and extends horizontally in the width direction continuously toward the outside (see FIG. 11).
The lower part 18D of the extension member 18A is formed to have a width narrower than the interval between these partitions so that it can be inserted between the partition 24JW of the enveloping plywood 24W and the partition 24JZ of the enveloping plywood 24Z. Further, the lower portion 18D is formed with an inclined surface 18E so that the thickness becomes thinner toward the tip (see FIGS. 11 and 20). Thereby, the extension member 18A can be raised without the outer skin material D sticking to the lower part 18D after the extension step described later. However, depending on the properties of the outer skin material D, the thickness of the extension member 18A may be constant.
The actuator 18B is, for example, a fluid pressure cylinder, and can change the stroke of the slide rod as desired. The frame mechanism 18C connects the upper end of the slide rod of the actuator 18B and the upper end of the extension member 18A.

The extension member 18A moves up and down relative to the holding member 15B as the elevating frame 15A moves up and down, and also moves up and down with respect to the holding member 15B through the operation of the actuator 18B. The lifting stop position of the extension member 18A relative to the holding member 15B is adjustable, but here it is set to a position where the lower end of the extending member 18A matches the lower end of the protruding strip 15D of the holding member 15B. The lowering stop position of the extension member 18A relative to the lowered pressing member 15B can be adjusted, but here, the lower end of the extension member 18A enters the gap 23B of the wrapping plate 24 in the open state, and the lower end of the extension member 18A reaches the end 24B of the wrapping plate 24. It is set at a position that coincides with the lowermost small protrusion 24H that protrudes from.

The support device 17 is disposed below the packaging device 13, supports the outer skin material D, and further conveys the folded food product P to a carry-out conveyor 19, which will be described later. The support device 17 includes two belt conveyors 17A corresponding to each packaging unit 23 and a conveyor 17B between the belt conveyors 17A. The vertical position and vertical speed of the belt conveyor 17A, as well as the driving timing and driving speed of the belt conveyor 17A and the transport conveyor 17B are adjustable and controlled by a control device 21. The carry-out conveyor 19 is a belt conveyor connected to the downstream side of the support device 17, and is a device that receives the folded food product P from the support device 17 and further carries it out to the downstream side. When a contact member (not shown) such as a roller is provided above the carry-out conveyor 19, the folded food P is conveyed in a horizontally laid state (see FIG. 2).

Next, with reference to FIGS. 1 to 16, a process of forming the folded food product P using the forming apparatus 1 according to the first embodiment of the present invention will be described. As described above, the flat skin material D rolled from the adjusted dough ball DD is molded into a circular shape by the skin material forming device 4, having a linear protuberance DS along the width direction on its upper surface. be done. The conveyance of the outer skin material D is temporarily stopped below the nozzle 5E of the inner material supply device 5, and the required amount of inner material F is discharged from the inner material supply device 5 to the center of the outer skin material D. installation process). The outer skin material D on which the inner material F is placed is transported from the transport conveyor 5A to the supply conveyor 11 of the folding and forming device 7 (see FIGS. 1 and 2).

The wrapping unit 23 of the wrapping device 13 is waiting with the pair of wrapping plates 24 (24W, 24Z) opened and separated from each other. Further, the elevating frame 15A is stopped at the raised position together with the positioning member 16A, the pressing member 15B, and the extension member 18A. The positioning member 16A is in a lowered position relative to the pressing member 15B as the lifting actuator 16B moves forward. Further, the approach/separation actuator 16C moves forward, and the pair of positioning members 16A are separated. The elevating actuator 18B moves forward and the extension member 18A is at a raised position relative to the pressing member 15B. This state is called the initial state (see FIGS. 3 to 5).

The distal end portion 11A of the supply conveyor 11 is at a standby position where it is shrunk toward the upstream side in the X direction within the range of reciprocating movement. When the sensor 11B senses the outer skin material D being conveyed, the tip portion 11A moves downstream along the X direction. The distal end portion 11A stops moving at the advanced position where it extends so as to cover the upper part of the packaging unit 23. Then, the supply conveyor 11 stops conveying the outer covering material D at a position where the center LD of the outer covering material D coincides with the center 23AO of the opening 23A of the packaging unit 23W in plan view (see FIG. 5). Specifically, two outer covering materials D are placed on the tip portion 11A apart from each other along the X direction.

Next, the tip 11A retreats at once, and the downstream outer skin material D placed on the tip 11A is transferred onto the placement surface 24C of the pair of packaging plates 24 of the downstream packaging unit 23W. Ru. Subsequently, the supply conveyor 11 stops conveying the outer covering material D at a position where the center LD of the upstream outer covering material D coincides with the center 23AO of the opening 23A of the upstream packaging unit 23Z. Next, the tip 11A retreats all at once, and the upstream skin material D placed on the tip 11A is transferred onto the placement surface 24C of the pair of packaging plates 24 of the upstream packaging unit 23Z. be done. At this time, the outer skin material D enters into the opposing inclined surface 24F due to the weight and fall of the inner material F, and becomes depressed. Further, the peripheral edge portions DB of the skin material D located on the curved surfaces 24G on both sides in the width direction and the gap 23B (here, including the edge portions on both sides of the raised portion DS) slightly enter the gap 23B and become depressed. (Placement process, see Figure 6).

When the distal end portion 11A retreats to the standby position at the upstream end, the positioning member 16A, the pressing member 15B, and the extension member 18A descend toward the packaging unit 23 due to the lowering of the elevating frame 15A. A pair of positioning members 16A separated from each other descend to the mounting outer circumferential surface 24D of the packaging plate 24, and are arranged on the upstream and downstream sides of the outer covering material D in the X direction (see FIG. 7).

The actuator 16C moves back, the pair of positioning members 16A approach each other, surround the outer skin D, and the inner surface 16AS presses the outer periphery of the outer skin D toward the center to position the outer shape of the outer skin D. It is molded along the inner surface 16AS of the mating member 16A. Further, the center LD of the outer skin material D is aligned with the center 23AO of the opening 23A of the packaging unit 23. At this time, the alignment member 16A slightly pushes the outer skin material D onto the inclined surface 24F (alignment step, see FIG. 8).

Further, as the elevating frame 15A descends, the pressing member 15B and the extension member 18A descend. At this time, as the lifting actuator 16C moves back, the positioning member 16A remains on the mounting outer circumferential surface 24D of the wrapping plate 24, and the pressing member 15B moves against the positioning member 16A and the wrapping unit 23. descend. The pressing member 15B descends without contacting the inner material F, and the semicircular pressing surface 15C on the lower surface of the pressing member 15B presses the peripheral edge DA of the outer skin material D against the placement outer peripheral surface 24D of the packaging plate 24.

Further, each protruding portion 15D of the pressing member 15B presses the peripheral end portion DB, which is a part of the peripheral portion DA, against each curved surface 24G of the pair of envelope plates 24 (24W, 24Z) in a separated state. The center of the peripheral edge portion DB is pushed into the gap 23B by the protruding portion 15D. The peripheral edge portion DB is folded in two along the shapes of the protruding portion 15D and the curved surface 24G. The outer shape of the peripheral edge DA of the outer skin material D is formed into a circular shape along the inner surface 16AS of the alignment member 16A (see pressing step, FIG. 9).

Compressed air A2 is supplied from the compressor 30 to the internal space 15E of the holding member 15B for the required time T, and acts to increase the air pressure in the internal space 15E. The central portion of the outer skin material D expands (indents) downward along the slope 24F due to the air pressure of the compressed air A2 through the inner material F, and finally passes through the opening 23A of the packaging unit 23 and expands downward, forming a bowl. The inner material F is arranged inside the bowl-shaped outer skin material D.

The belt conveyor 17A is on standby below the packaging device 13 at a required interval from the packaging board 24. The upper surface of the belt conveyor 17A supports the bottom of the outer skin material D that expands downward, thereby preventing the outer skin material D from being deformed more than necessary, stabilizing the shape of the outer skin material D, and improving the shape of the outer skin material D. The position of the head FT of the inner material F with respect to the peripheral portion DA is determined (bowl-shaped forming step, inner material arrangement step, support step, see FIG. 10).

The fabric of the raised portion DS formed on the outer skin material D is stretched thinly through a pressing process, a bowl-shaped forming process, and a supporting process. However, by providing the outer covering material D in advance with a thick portion of the fabric, it is possible to prevent the fabric thickness at the bottom of the formed folded product P from becoming excessively thin.

The lifting actuator 18B moves back, and the pair of extension members 18A are guided by the vertical grooves 15S of the holding member 15B and move between the pair of wrapping plates 24 to the set position (here, a small protrusion on the lower side of the wrapping plate 24Z). 24HZ), and pushes the peripheral end DB of the outer skin material D downward. The turned portion where the peripheral edge portion DB of the outer skin material D is folded in half is lowered relative to the head portion FT of the inner material F. By providing a non-horizontal inclined portion such as an R chamfer on the inside of the lower end of the extension member 18A, it is possible to suppress the outer skin material D from being pushed out to the outside (here, in the width direction). In addition, since the peripheral edge portion DB is covered with a pair of partitions 24J (24JW, 24JZ) on the sides in the width direction, it is prevented from stretching in the width direction, and the appearance of the folded food P can be adjusted ( extension process, see Figure 11).

The actuator 16C moves forward, and the pair of positioning members 16A separates from each other and from the pressing member 15B and the outer covering material D (see FIG. 12). The lifting actuator 18B moves forward, and the pair of extension members 18A rises and returns to the lifting stop position relative to the pressing member 15B. When the extension member 18A rises, the small protrusions 24H of the enveloping plate 24 engage with the skin material D (here, the peripheral end DB) extended within the gap 23B, and the skin material D contracts upward. (See Figure 13). Further, as described above, since the lower part 18D of the extension member 18A is formed with the inclined surface 18E so that the thickness becomes thinner toward the tip, the outer skin material D is extended when the extension member 18A is raised. It adheres to the member 18A and prevents the return portion from being pulled upward and contracted (see FIG. 20).

The elevating frame 15A rises together with the positioning member 16A, the pressing member 15B, and the extension member 18A, and each member returns to its initial position. The drive shaft 26G swings (forward movement) counterclockwise in plan view, and the slide mechanism 26 starts moving forward. At this time, the clutch mechanisms 28A and 28B fix the shafts 27D and 27J, respectively, and approach each other. The pair of envelope ply plates 24 (24W, 24Z) that had been separated move toward each other, and the gap 23B formed between each envelope ply plate 24 narrows. The peripheral end portion DB located in the gap 23B is compressed between the end portions 24B of each wrapping plate 24 and flattened. The peripheral edge portion DB where the skin material D overlaps is reliably sealed and becomes the end sealing portion DR of the folded food product P. Furthermore, a new groove DZ is formed at the upper end of the end sealing portion DR (squeezing step, see FIG. 14).

After the pinching process is completed, the clutch mechanisms 28A and 28B release the shafts 27D and 27J, respectively, and the link mechanism 27 starts swinging (forward movement). Each packaging plate 24W, 24Z swings to close, and the peripheral edge DA of the outer skin material D (downstream peripheral edge DAW and upstream peripheral edge DAZ, see FIG. 14) are folded and overlapped, and the facing mounting surfaces 24C (gap 23C), and the folded food product P is formed. In the folded food product P, there is no leakage of the inner material F from the outer skin material D, and the arc-shaped sealing portion DF where the peripheral portions DA overlap is reliably sealed (see sealing step, FIG. 15).

After the sealing process is completed, the drive shaft 26G swings clockwise (backward movement) and the slide mechanism 26 starts to move back. At this time, the clutch mechanisms 28A and 28B fix the shafts 27D and 27J, respectively, and separate from each other. The folded food product P is released from the packaging unit 23 by separating the packaging plates 24W and 24Z (release process, see FIG. 16). The folded food product P descends together with the belt conveyor 17A, is transferred to the carry-out conveyor 19 at the lower end position, and is further carried out to a secondary forming device, a heat treatment device, etc. (carry-out step).

Thereafter, the clutch mechanisms 28A and 28B release the shafts 27D and 27J, respectively, and switch to a freely rotatable state, the link mechanisms 27A and 27B swing in the opposite direction (backward movement), and the pair of wrapping plates 24W and 24Z Swinging in the opening direction, the two packaging units 23W and 23Z return to the open state (initial state) (see FIG. 5).

In the above description, the folded food product P was formed from the skin material D having the raised portion DS. The thickness of the raised portion DS becomes thinner in a bowl-shaped forming step in which the central portion of the outer skin material D is expanded and in an extension step in which the peripheral edge portion DB of the outer skin material D is stretched. However, by forming the raised portion DS thicker than other parts of the outer skin material D in advance, in the final product after firing or evaporation, the bottom part of the product is prevented from becoming excessively thin, and the inner material F This can solve problems such as leakage and poor texture of the product.

In the first embodiment described above, the folded food product P is formed using the positioning device 16 and the extension device 18 together with the pressing device 15. Here, the effects of the positioning device 16 and/or the extension device 18 will be explained starting from the shape of the folded food product P.

FIG. 17 is a perspective view showing the folded food P laid down on its side. The figure (a) shows a folded food product P formed using only the pressing device 15 without using the alignment device 16 and the extension device 18. The figure (b) shows a folded food product P formed using the pressing device 15 and the extension device 18 without using the positioning device 16. FIG. 18 is a perspective view showing the folded food P laid down on its side. The figure (a) shows a folded food product P formed using the positioning device 16 and the pressing device 15 without using the extension device 18. The figure (b) shows a folded food product P formed using a pressing device 15, a positioning device 16, and an extension device 18.

By comparing FIG. 17 and FIG. 18, it is possible to understand the effect of molding depending on whether or not the positioning device 16 is used. When the alignment device 16 is not used, the outer skin material D supplied to the packaging unit 23 has an outer shape formed by the outer skin material molding device 4. Therefore, the width of the overlapping peripheral edge portion DA is relatively wide and sealed. Furthermore, if the positioning device 16 is not used, the position may shift with respect to the wrapping unit 23. The overlap of the folded peripheral edges DA is not uniform, and one side is irregularly shifted from the other, resulting in a problem that the quality of the folded food product P and furthermore the final product is degraded. Therefore, by using the alignment device, the above problem can be solved and the folded food product P can be stably formed.

Next, in FIGS. 17 and 18, by comparing FIGS. 17A and 18B, it is possible to understand the effect of molding depending on whether or not the extension device 18 is used. The folded food product P shown in the figure (a) is formed into a pressing process (FIG. 14) after the bowl-shaped forming process (see FIG. 11) without passing through the extension process (see FIG. 13). On the other hand, in the drawing (b), in the extension process, the turned portion in which the peripheral edge portion DB of the outer skin material D is folded in half is pushed down against the head FT of the inner material F arranged inside the outer skin material D. The position of the end sealing part DR of the folded food P shown in FIG. ing. Further, as described above, the lowering stop position of the extension member 18A in the extension process is adjustable, and the range (length) of the sealing part DF of the outer skin material D formed around the inner material F is adjusted. be able to. Therefore, various folded foods P having different appearances can be formed.

FIG. 19 is a perspective view showing the folded food product P. For example, it is a curry bread in which the outer material D is the dough and the inner material F is the curry filling. The folded food product P formed by the forming device 1 is placed on a top plate or the like with the sealed portion DF facing upward without being turned sideways. By molding the range (length) of the sealing part DF of the outer skin material D around the inner material F to be relatively long, it is possible to easily mold it into an oval spherical shape as shown in FIG.

Although the description of the folded food product P forming apparatus 1 according to the embodiment of the present invention is generally as described above, it is not limited thereto, and various changes can be made within the scope of the claims. In the above description, it has been explained that the packaging boards 24W and 24Z are provided with the partitions 24JW and 24JZ, respectively, but one of the packaging boards 24 is provided with continuous partitions at both ends 24B in the width direction, and the other part is provided between the pair of partitions. The wrapping unit 23 may be configured so that the ends 24B on both sides of the wrapping plate 24 can be inserted therein. By raising and lowering the extension member 18A between the pair of partitions and between the opposing ends 24B, the outer skin material D is prevented from stretching in the width direction, and the folded food product P of a predetermined width can be formed. Can be done.

Furthermore, although the description has been made so that the outer skin material D is molded into a circular shape, it is also possible to mold it into a polygonal shape, an elliptical shape, etc. by changing the shapes of the outer skin material molding device 4 and the positioning device 16. Furthermore, by changing the arrangement of the positioning device 16 with respect to the wrapping unit 23, it is possible to shift the placement position of the outer skin material D relative to the opening 23A to a desired position, and the peripheral edge of the folded outer skin material D can be shifted to a desired position. It is also possible to adjust the overlap of the peripheral edge portions DA so as to form a folded food product P in which the overlap of the DA is slightly shifted.
Furthermore, the pair of positioning members 16A can be a combination of positioning members 16A whose inner surfaces 16AS have different shapes, and the folded food product P in which the overlap of the peripheral edge DA of the folded outer skin material D is shifted can be formed. It is also possible to mold it.

In the above description, the bowl-shaped forming device is configured as an air pressure raising device that increases the air pressure in the internal space 15E of the pressing member 15B. However, for example, as shown in FIGS. 11 to 13 of Patent Document 4, there is a nozzle that supplies the inner material F to the outer skin material D so as to form the outer skin material D into a bowl shape with the discharge pressure of the inner material F, The inner material supplying device may include a feeding device that supplies the material F. Further, for example, the outer skin material D is formed into a bowl shape by being arranged movably inside a pressing member as shown in FIGS. 14 to 17 of Patent Document 4 and pushing the outer skin material D downward from the opening of the wrapping unit. The pushing device may include a pushing member that supplies the inner material F from the pushing member and a feeding device that supplies the inner material F to the pushing member so as to arrange the inner material F on the outer skin material D. In either device, the inner material F can be placed on the outer skin material D.

Moreover, although it has been described that the end portion 24B of the envelope plate 24 is provided with the small protrusion 24H, for example, a concave dimple such as a small spherical depression may be provided on the surface of the end portion 24B. By engaging with the outer skin material D (peripheral edge portion DB in the above description) that is stretched between the outer skin members D, the outer skin material D can be prevented from shrinking upward. Furthermore, the small protrusions 24H and/or dimples may be formed on at least one of the opposing ends 24B.
