In the configuration described in Patent Document 1, when the other plate is reversed and folded over to one plate, the main plate has no gap on the facing surface, and a recess is formed with respect to the capacity of the folded food. When the capacity of the space to be used is small, there is a problem that the inner material leaks from between the folded dough and the peripheral portions do not seal. Furthermore, when the other plate returns to its original position, there is a problem that the dough adheres to the plate and the sealing portion opens again.

In the configuration described in Patent Document 2, the outer material is recessed in the concave portion of the pallet using a pressing device, and the inner material is supplied from the inner material supply device to the recess of the outer material. Such a pressing device complicates the structure of the entire device.

Further, in the conventional apparatus, when one pallet is rotated from the horizontal state to the upper side of the other pallet and the joint surface of the pallet is separated and the lower part is opened, the outer skin material and the folded food fall from this opening. There was a problem. Therefore, in the conventional apparatus, the inner material cannot be placed at the center of the outer skin material, and the inner material is unevenly distributed on the upper surface of the outer skin material. However, if the inner material is unevenly distributed with respect to the outer skin material, it will be easy to leak the inner material, so it is necessary to prepare a wide peripheral portion of the outer skin material on which the inner material is not placed. I couldn't do much.

An object of the present invention is to provide a method for forming a folded food and a forming apparatus for the folded food that can be stably folded without causing the above problems.

The present invention is for solving the above-described problem, and is a method for forming a folded food product in which a flat outer skin material is folded and an inner material is wrapped, and a pair of pallets including a lower mold and an upper mold arranged to face each other. When folding the outer skin material on which the inner material is placed, the center portion of the outer skin material is supported by the placement portion protruding from the opposing surface side of the lower die above the concave portion of the upper die.

A folded food molding apparatus 1 according to an embodiment of the present invention will be described with reference to FIGS. Here, the explanation will be made on the assumption that the folded food P, which is a confectionery bread that wraps the outer material D of the bread dough and wraps the inner material F of the cream inside, is formed. The molding apparatus 1 is attached to the base 3 and is disposed between a supply conveyor 5 that supplies the outer skin material D to the molding apparatus 1 and a carry-out conveyor 7 that carries out the folded food P. The supply conveyor 5 is a sliding conveyor provided with a downstream end portion 5 </ b> A that can be advanced and retracted above the molding apparatus 1. Here, the direction in which the supply conveyor 5 transports the outer skin material D will be described as the transport direction Y. Further, the carry-out conveyor 7 has an upstream end portion 7 </ b> A disposed on the downstream side of the forming apparatus 1.

The molding apparatus 1 includes a pair of an upper pallet 11 disposed on the upstream side of the transport on the upper surface of the base plate 9 and a lower pallet 31 disposed on the downstream side thereof. In this description, the upper pallet 11 and the lower pallet 31 may be collectively referred to as a pallet. The upper pallet 11 includes an upper swing bracket 13, a pedestal 15, and an upper mold 17. The upper swing bracket 13 is formed in a U-shape, and includes a bottom plate 13A lying horizontally and side plates 13B and 13C bent upward (upper side in FIG. 2) at both ends (upper and lower ends in FIG. 1). ing. Further, the upper mold 17 is attached to the upper surface of the bottom plate 13A via the pedestal 15.

On the upper surface of the base plate 9, fulcrum plates 19 and 21 disposed on both sides of the upper swing bracket 13 are attached. Support shafts 23 and 25 are attached to the side plates 13B and 13C, which are both end faces of the upper swing bracket 13, and are rotatably supported by fulcrum plates 19 and 21 via bearings, respectively. Further, a rotary actuator 27 is connected to the support shaft 23, and the upper pallet 11 is swingably provided by the rotational drive of the actuator 27.

The lower pallet 31 includes a lower swing bracket 33, a pedestal 15, and a lower mold 35. The lower swing bracket 33 includes a bottom plate 33A and side plates 33B and 33C bent upward at both ends thereof. Further, the lower die 35 is attached to the upper surface of the bottom plate 33A via the pedestal 15.

Support shafts 37 and 39 are attached to the side plates 33B and 33C, which are both end faces of the lower swing bracket 33, and are rotatably supported on the fulcrum plates 19 and 21 via bearings, respectively. Further, a rotary actuator 41 is connected to the support shaft 37, and the lower pallet 31 is swingably provided by the rotational drive of the actuator 41.

The upper mold 17 and the lower mold 35 are arranged in pairs along the transport direction Y with a slight gap therebetween. Here, a virtual surface passing through an intermediate position where the upper mold 17 and the lower mold 35 face each other is referred to as a bonding surface, and the opposite side surfaces are referred to as opposed surfaces 17A and 35A, respectively.

The upper mold 17 has a curved recess 43 extending from the opposing surface 17A to the upper surface 17B. Further, the upper surface 17B is provided with a plurality of small holes 45 along the edge 43A of the recess 43 on the outer side. These small holes 45 communicate with a passage 46 formed in an arc shape in the upper mold 17. Further, the passage 46 communicates with a duct 61 below the base plate 9 through a pipe, and the duct 61 communicates with an intake / exhaust device such as a blower (not shown).

The lower die 35 is formed with a mounting portion 47 that protrudes upward from the concave portion 43 of the upper die 17 facing the lower die 35. Further, a curved concave portion 49 is formed on the upper surface 35B of the lower die 35 from the front end side of the placement portion 47 to the main body portion of the lower die 35 with the opposing surface 35A as a central position. Further, the upper surface 35B is provided with a plurality of small holes 51 which are outside the edge portion 49A of the concave portion 49 and symmetrical with the small holes 45 of the upper mold 17 with the joint surface as the center. These small holes 51 communicate with a passage 52 formed in an arc shape in the lower mold 35, and are communicated with an intake / exhaust device via a pipe and a duct 61 like the small holes 45. Therefore, the small hole 45 and the small hole 51 function as an intake port and an exhaust port.

The swing mechanism of the upper pallet 11 will be described. As described above, the upper pallet 11 is provided so as to be swingable about the support shafts 23 and 25. The rotation centers of the support shafts 23 and 25 are arranged at a height slightly above the upper surface 17B of the upper mold 17 on the joint surface. Therefore, when the actuator 27 is operated to rotate the upper pallet 11 in the horizontal state 180 degrees above the lower pallet 31, the upper die 17 is reversed and a gap is formed between the upper surface 17B and the upper surface 35B facing each other. Further, the recess 43 of the upper mold 17 covers the recess 49 of the lower mold 35.

The swing mechanism of the lower pallet 31 will be described. As described above, the lower pallet 31 is provided so as to be swingable about the support shafts 37 and 39. The rotation centers of the support shafts 37 and 39 are arranged at the center height of the lower pallet 31 on the downstream side surface of the lower mold 35. Therefore, when the actuator 41 is operated and the lower pallet 31 in the horizontal state is rotated 180 degrees downstream, the lower die 35 is reversed and the upper surface 35B is opposed to the conveying surface of the carry-out conveyor 7.

Next, the forming process of the folded food P will be described. Here, a description will be given of a case where the supply material 5 is supplied to the molding apparatus 1 with the inner material F placed in the center of the flat outer skin material D. In addition, the state shown in FIG. The outer skin material D on which the inner material F is placed is horizontally conveyed by the supply conveyor 5 and conveyed above the opposing upper pallet 11 and the lower pallet 31, and the center of the outer skin material P and the upper die 17 and the lower die 35. It is temporarily stopped at a position where the joint surface that is the center position coincides (see FIG. 5A).

The downstream end 5A of the supply conveyor 5 moves backward without moving the conveying surface, and the outer shell material D falls and is supplied to the molding apparatus 1 in the initial state. The central portion of the outer skin material D is supported by the concave portion 49 of the lower die 35, and the peripheral edge portion of the outer skin material D is supported by the upper surface 17B of the upper die 17 and the upper surface 35B of the lower die 35 (see FIG. 5B).

The intake / exhaust device performs an intake operation and sucks the peripheral edge portion of the outer skin material D from the small hole 45 and the small hole 51. Then, the actuator 27 is operated to rotate the upper mold 17 above the lower mold 35. When the upper die 17 starts to rotate, the upper die 17 and the lower die 35 facing each other are separated, and the concave portion 43 is opened downward. However, since the lower die 35 is provided with the mounting portion 47 that protrudes toward the upper die 17, the center portion of the outer skin material P and the inner material F can be supported. Therefore, the outer skin material P does not slide off from the pallet (see FIG. 5C).

Further, the upper die 17 rotates and reversely moves upwardly from the lower die 35. The outer skin material D is folded so as to wrap the inner material F, and the folded food P is formed (see FIG. 5D). In this folding process, since the peripheral edge of the outer skin material D is sucked from the small holes 45 and 51, the peripheral edges overlap each other without being displaced from the upper mold 17 and the lower mold 35, and the upper mold 17 and The pressure is sandwiched between the lower molds 35. Further, the cloth at the center of the outer skin material D extends around the inner material F and covers the inner material F. Therefore, the peripheral part of the folded food P is sealed and the inner material F does not leak out.

Then, the air intake / exhaust device performs an exhaust operation to discharge air from the small holes 45 and 51 to the outer skin material D side, and the upper pallet 11 returns to the original position (see FIG. 5E). At this time, even if the outer skin material D and the upper die 17 adhere to each other, the outer skin material D is peeled from the upper die 17 by the exhaust from the small holes 45. Therefore, it does not cause the outer skin material D in which the upper mold 17 is folded, and the problem that the sealed portion of the folded food P is opened does not occur. The abdomen of the folded food P protrudes from the position of the joint surface 35A of the lower mold 35 to the upper mold 17 side. However, since the mounting portion 47 is provided so as to protrude above the concave portion 43 of the upper mold 17, even if the upper mold 17 moves backward and does not hold the folded food P, the folded food P is still in the lower mold. No sliding down from 35.

When the upper pallet 11 moves backward, the lower pallet 31 rotates 180 degrees around the support shafts 37 and 39 toward the carry-out conveyor 7 (see FIG. 5F). The folded food P is inverted and discharged from the lower mold 35 and transferred to the transport surface of the carry-out conveyor 7. The lower pallet 31 is moved back to the original position and returned to the initial position facing the upper pallet 11.

In the molding apparatus 1 according to the embodiment of the present invention, since the inner material F can be placed at the center of the outer skin material D as described above, the amount of the inner material F relative to the outer skin material D can be increased. In addition, the lower die 35 includes a mounting portion 47 that protrudes from the main body portion toward the upper die 17 that faces the lower die 35, and can support the central portion of the outer skin material D or the abdomen of the folded food P. The outer shell material D and the folded food P can be prevented from sliding off from the pallet at the time of folding molding, so that reliable folding molding can be performed stably and the conventional problems can be solved.

The description of the apparatus 1 for forming a food dough piece according to the embodiment of the present invention is generally as described above. However, the present invention is not limited to this, and various modifications can be made within the scope of the claims. For example, when the upper mold 17 and the lower mold 35 are provided with the small holes 45 and the small holes 51, which are the intake and exhaust ports, respectively, when the position of the outer skin material D on the lower mold 35 does not shift, Only the mold 17 may be provided with the small holes 45 so that the outer skin material D is sucked and peeled off. In addition, although it has been described that intake and exhaust are performed from the small holes, only intake when the outer skin material D is folded may be performed. Furthermore, folding can be performed without providing a hole in the mold due to the adhesiveness between the mold and the outer skin material D.

In the above description, the upper pallet 11 and the lower pallet 31 in the horizontal state are provided to rotate in the same direction. However, the lower pallet 31 is provided to rotate 90 degrees in the direction opposite to the upper pallet 11, and the folded food. It is also possible to discharge P below the pallet. In this case, the carry-out conveyor 7 may be disposed below the molding apparatus 1 and wrapped in the base plate 9 so that the food P can pass therethrough.
