Description

  The present invention relates to a food wrapping method and apparatus, and more particularly, food wrapping capable of reliably wrapping and forming inner materials such as rice cakes, cooked meat and vegetables with outer skin materials such as bread dough and bun dough The present invention relates to a molding method and a food wrapping and molding apparatus used therefor.

  Conventionally, as a technology related to food molding that wraps the inner material such as rice cake, cooked meat, vegetables, etc. with outer skin materials such as bread dough and bun dough, the inner material is made into a rod shape and the outer skin material is cylindrical It is formed continuously, and this is narrowed down by an opening / closing operation of a shutter mechanism to be molded and cut (see, for example, Patent Document 1). However, when fermenting dough such as bread dough is used as the skin material, excessive pressure or twisting is applied to the dough when it is formed into a cylindrical shape, so that the dough does not swell sufficiently after forming and cutting, and the skin material is elastic. There is a difficulty that it becomes a hard food with poor properties, and the molding process is done manually.

There has also been proposed a method of forming a food from a sheet-like skin material while avoiding such tubular formation of the skin material. For example, Patent Document 2 describes that dough and straw are put in a cup and the dough is sealed by a sealing gate. In Patent Document 3, an outer packaging material is formed in a bowl shape along the inner wall surface of a cup-shaped female mold whose upper surface is open, and after the inner material is supplied into the outer packaging material formed in the bowl shape, It is described that the upper edge of the material is squeezed with a shutter composed of a plurality of shutter pieces to seal the upper edge of the outer packaging material and wrap the inner material. When the outer wrapping material is squeezed and sealed with the shutter piece, a plug is disposed in the female opening so as to prevent the squeezed outer wrapping material from protruding above the shutter piece.

  In this way, when forming from a sheet-like skin material, foodstuffs such as bread dough have flexibility, and the shape of the skin material is not constant, and it may be an elliptical shape that varies slightly one by one. In addition, since it has adhesiveness, it is necessary to consider that it cannot be accurately placed at the molding position due to misalignment during conveyance. In the conventional food molding method described above, when the outer skin material is elliptical or when the outer skin material is supplied to a position deviated from the molding position, it is likely that the outer skin material cannot be sealed. If the piece is not placed on the periphery of the cup, the edge of the dough piece falls in the subsequent process, and sealing becomes impossible. In order to avoid this, it is conceivable to enlarge the fabric piece, but in this case, the amount of the fabric piece increases, so that the fabric piece may protrude above the sealing gate when the sealing gate is closed. There is. The same thing can be said in Patent Document 3, and the plug prevents the outer skin material from protruding. However, the number of processes increases because the plug is arranged in the female mold, and the process such as moving the female mold on which the outer skin material is placed is performed. In addition, there is a problem that the entire apparatus is enlarged due to the necessity of arranging a large number of female molds, and the apparatus mechanism is complicated.

  The present invention was made in view of the above-mentioned difficulties in the conventional food molding method, and even when there is a variation in the shape or displacement of the outer shell material, the outer shell material can be reliably used at the time of sealing. It is an object of the present invention to provide a wrapping molding method and a wrapping molding apparatus having a simple configuration capable of wrapping and molding an inner material.

  The method for wrapping and forming a food according to the present invention is a method in which a sheet-shaped outer covering material is supplied onto a receiving member in a state in which a shutter composed of a plurality of shutter pieces disposed above the receiving member is opened, and the shutter piece is closed. To adjust the position of the outer skin material so that the outer skin material fits in the specified position, and lowers the presser member together with the pushing member and presses the presser member against the edge of the outer skin material to receive the outer skin material on the receiving member. The pressing member is further lowered to enter the opening of the receiving member, the central portion of the outer shell material is pushed into the opening to form the outer shell material in a bowl shape, and the outer shell material is supported by the support member and pushed in. The inner material is supplied through the member, the inner material is arranged on the outer skin material, and the shutter is closed while the outer skin material is supported by the support member, thereby collecting the peripheral portion of the outer skin material so as to wrap the inner material. Sealed and lowers the support member, characterized in that for conveying the molded article.

  The food wrapping and forming apparatus according to the present invention includes a receiving member in which an opening is formed in a central portion and a sheet-like outer skin material is placed, and a plurality of shutter pieces disposed above the receiving member. The shutter is provided, and the shutter piece is moved in the closing direction to reduce the opening area thereof, adjust the position so that the outer skin material fits in a predetermined position, and close the shutter to operate the peripheral portion of the outer skin material. Shutter driving means that collects and seals in a wrapping manner, and lowers the pushing member to enter the opening of the receiving member to push the central part of the outer skin material into the opening to form the outer skin material like a bowl and through the pushing member The outer skin material forming means for supplying the inner material into the outer skin material, and the presser member that is provided on the outer skin material forming means and pressed against the edge of the outer skin material to receive the outer skin material on the member And holding means disposed below the receiving member and supporting means for raising the support member to support the outer skin formed in a bowl shape and lowering the support member to convey the molded product. It is characterized by that.

  According to the food wrapping and forming method and apparatus therefor according to the present invention, if the opening area is reduced by operating the shutter piece in the closing direction of the shutter, the outer skin material F is set in accordance with the reduced opening state. The position of the outer skin material F can be adjusted so that the outer skin material F is in a predetermined position. As a result, variations in the shape and position displacement of the skin material are corrected in advance, and a more reliable molding process can be performed.

  In addition, since the edge of the outer skin material is held by the pressing member when the outer skin material is formed in a bowl shape, even if the outer skin material is a foodstuff rich in elasticity such as bread dough, the outer edge of the outer skin material is stretched around the edge of the outer skin material. Even if the shape and size of the outer skin material varies somewhat or there is a positional shift, the outer skin material can be surely formed into a bowl shape. At this time, if the outer skin material is supported by the support member, it is possible to prevent the outer skin material from extending downward more than necessary.

  In addition, since the inner material is supplied through the pushing member, it is possible to prevent the outer skin material from contracting as the pushing member rises, and to efficiently form the outer skin material and supply the inner material in a short time. Can be performed. At this time, since the outer skin material is supported by the support member, it is possible to prevent the outer skin material from being unnecessarily stretched due to the discharge of the inner material, and the inner material can be reliably disposed inside the outer skin material.

  In addition, since the outer skin material is supplied onto the receiving member provided below the shutter, the outer skin material can be placed more stably, and the outer skin material can be reliably secured by the receiving member and the holding member of the holding means. In addition, by pressing the pushing member into the opening of the receiving member, it becomes possible to form the outer skin material using the opening of the receiving member.

  Further, since the outer skin material is supplied onto the receiving member provided below the shutter, the position of the outer skin material on the receiving member can be adjusted by the closing operation of the shutter, and the apparatus configuration can be greatly simplified. it can.

  Hereinafter, the food wrapping and forming process by the food wrapping and forming apparatus of the first reference example will be described with reference to FIGS. In this example, bread dough is used as the outer skin material F, and cocoon is used as the inner material G.

  First, as shown in FIG. 8C, the sheet-like skin material F is supplied onto the shutter piece 10 of the shutter 1 with the shutter 1 and the auxiliary shutter 2 opened. At this time, in order to place the outer skin material F more stably, the outer skin material F may be supplied onto the shutter piece 10 with the lower shutter 1 closed. Then, after placing the outer skin material F on the shutter piece 10, if the opening area is reduced by operating the shutter piece 20 of the auxiliary shutter 2 in the closing direction, the outer skin material F is adapted to the reduced opening state. The outer skin material F can be set and the position of the outer skin material F can be adjusted so that the outer skin material F is in a predetermined position. As a result, variations in the shape and position displacement of the skin material are corrected in advance, and a more reliable molding process can be performed.

  Next, as shown in FIG. 9 (c), the edge of the outer skin material F is held on the shutter piece 10 by the pressing member 50 of the holding means 5 by lowering the pushing member 30 of the upper skin material forming means 3. To do. That is, the holding means 5 is lowered together with the pushing member 30 to bring the holding member 50 into contact with the edge of the outer skin material F, and the holding means 5 is further lowered to narrow the gap between the holding member 50 and the stay 52. The coil spring 53 is compressed, and the holding member 50 is pressed against the edge of the outer skin material F using the elastic force of the coil spring 53 to hold the outer skin material F on the shutter piece 10.

  Then, as shown in FIG. 10 (c), with the holding member 50 holding the edge of the outer skin material F, the pushing member 30 is further lowered to cause the pushing member 30 to enter the opening of the shutter 1, By pressing the central portion of the sheet-like outer skin material F into the opening of the shutter 1, the outer skin material F is formed in a bowl shape. In this way, when the outer skin material F is formed in a bowl shape, the edge of the outer skin material F is held by the holding means 5, so even if the outer skin material F is a foodstuff rich in elasticity such as bread dough, It can be formed in a bowl shape while extending the periphery of the edge, and even if the shape and size of the outer skin material is somewhat varied or misaligned, the outer skin material can be reliably formed in a bowl shape. At this time, if the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material from extending downward more than necessary.

  Next, as shown in FIG. 11 (c), the inner member G is discharged by raising the valve 40 in the pushing member 30 while raising the pushing member 30 to open the discharge hole, and the outer skin formed in a bowl shape. The inner material G is disposed inside the material F. Then, when a predetermined amount of the inner material G is discharged, the valve 40 is lowered to close the discharge hole. Thus, since the inner member G is supplied through the pushing member 30 at the same time that the pushing member 30 is raised, it is possible to prevent the outer skin material F made of bread dough from contracting as the pushing member 30 rises. At the same time, it is possible to efficiently form the outer skin material F and supply the inner material G in a short time. At this time, since the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material F from being unnecessarily stretched due to the discharge of the inner material G, and the inner material G is securely attached to the inner side of the outer skin material F. Can be arranged.

  Next, as shown in FIG. 12 (c), the push-in member 30 is further raised to separate the presser member 50 from the edge of the outer skin material F, and the auxiliary shutter 2 is closed as shown in FIG. 13 (c). The edge of the skin material F on the shutter piece 10 is pushed by the shutter piece 20 and the support member 60 is lowered while operating to place the edge of the skin material F on the side surface of the shutter piece 10. The above is the arrangement process of arranging the inner material G on the outer skin material F.

  Then, as a sealing process by the shutter 1, as shown in FIGS. 14 (c) and 15 (c), each shutter piece 10 is operated by closing the shutter 1 with the outer skin material F supported by the support member 60. The peripheral edge portion of the outer skin material F is collected and sealed so as to wrap the inner material at the rear end portion 10c of the side surface of the shutter, and the rear end portions 10c of the shutter pieces 10 are completely closed as shown in FIG. 16 (c). By doing so, a molded product H in which the inner material G is wrapped with the outer skin material F is obtained. Thereafter, the support member 60 that supports the molded product H is lowered to place the molded product H on the belt, and the belt conveyor 63 is driven to convey the molded product H to the belt.

  In this way, the peripheral edge portion of the outer skin material is sealed by the rear edge portion 10c that is closed later than the front edge portion 10a of each shutter piece 10, and therefore, as shown in FIGS. 14 (c) and 15 (c). As described above, it is possible to seal the peripheral edge portion of the outer skin material F with the rear edge portion 10c in a state where the front edge portions 10a or the inclined surface portions 10b of the shutter piece 10 are closed. Even if there is a deviation and the amount of fabric at the peripheral edge of the outer skin material varies slightly, the outer skin material does not protrude above the shutter 1 at the time of sealing, and the inner material can be reliably wrapped and molded with the outer skin material. is there.

  As shown in FIG. 14 (c), the peripheral edge portion of the outer skin material F is collected mainly at the rear edge portion 10c of the shutter piece 10, and the collected peripheral edge portion is sealed with the rear edge portion 10c as it is. (See FIG. 15 (c)), for example, the peripheral portion of the shell-shaped outer skin material is collected by the front edge portion 10a of the shutter piece 10, and then the collected peripheral portion is sealed by the rear edge portion 10c. You may do it. When sealing at least the peripheral edge portion of the outer skin material with the rear edge portion 10c, if the front edge portions 10a or the inclined surface portions 10b are closed, it is possible to prevent the outer skin material from protruding. In the stage before wearing, the front edge portions 10a of the shutter piece 10 may be opened, or the front edge portion 10a and the outer skin material F may be in contact with each other.

  Further, as shown in FIG. 16C, the molded product H is obtained by closing the shutter 1 until the rear end portions 10c of the shutter pieces 10 are completely closed, but the rear end portion 10c is not necessarily obtained. It is not necessary to close the shutter 1 until the two are completely closed. If the edge of the outer shell material is sealed, for example, the closing operation of the shutter 1 is finished at the stage of FIG. You may make it obtain goods. This makes it possible to obtain a molded product with relatively little fabric damage at the sealed portion.

  In addition, after the outer skin material is formed in a bowl shape, the inner material G is disposed inside the outer skin material F. For example, in the state where the inner material G is placed on the outer skin material F in advance, the outer skin material F is disposed. The material F may be supplied onto the shutter piece 10 of the shutter 1, and the outer material F may be pressed into the opening of the shutter 1 together with the inner material G by the pushing member 30, so that the outer material F is formed in a bowl shape. Further, as the support means 6 for supporting the outer skin material F and the molded product H, the support member 60 is formed in a plate shape so that the belt of the belt conveyor 63 is moved up and down, but the belt conveyor itself is moved up and down. Also good.

  Further, as shown in FIGS. 17 to 19, a receiving member 7 made of a thin plate for receiving the outer skin material F is sandwiched between the shutter 1 and the auxiliary shutter 2, and as shown in FIG. If the circular opening 70 is opened at the center of the outer shell material F, the outer skin material F can be more stably placed on the receiving member 7 (see FIG. 17), and the receiving member 7 and the holding means 5 The outer cover material F can be securely held by the holding member 50 (see FIG. 18), and the pushing member 30 is advanced into the opening 70 of the receiving member 7 so that the opening 70 of the receiving member 7 is opened. It is also possible to form the outer skin material F in the form of a bowl using (see FIG. 19).

  Further, as shown in FIGS. 21 to 24, the auxiliary shutter for adjusting the position of the skin material supplied onto the shutter piece 10 and the holding means for holding the edge of the skin material on the shutter piece 10 are omitted. This also makes it possible to simplify the apparatus configuration and the molding process. In this case, as shown in FIGS. 22 and 23, if the edge portion of the outer shell material that is pushed in by the pushing member 30 is supported by the front edge portion 10a of the shutter piece 10, the outer skin material F It is possible to prevent the edge portion of the body from falling outside. Thereafter, as shown in FIGS. 23 and 24, if the support member 60 is lowered in accordance with the closing operation of the shutter 1, the edge portion of the outer covering material can be sealed by the rear edge portion 10c of the shutter piece 10. .

Press and hold the edge of the outer skin material.

  Also, in FIG. 25, what is indicated by reference numeral 6 is a belt conveyor disposed below the skin material forming means 3, which is a molded product H separated from the retracting member 34 of the skin material forming means 3 after being molded. Is conveyed by belt (see Fig. 33).

  Hereinafter, the food wrapping molding process by the food wrapping molding apparatus of the second reference example will be described with reference to FIGS.

  First, as shown in FIG. 26, with the auxiliary shutter 2 opened, a sheet-like outer skin material F is placed on the shutter piece 10 of the shutter 1. On the outer skin material F, an inner material G is arranged in advance by an inner material supply means (not shown). At this time, the retracting member 34 of the outer skin material forming means 3 is raised to enter the opening of the shutter 1 in advance, and the outer skin material F is supplied onto the retracting member 34 and the shutter piece 10 of the shutter 1. By doing so, the outer skin material F can be placed more stably. As in the first reference example, after the outer skin material F is placed on the shutter piece 10 of the shutter 1, the shutter piece 20 of the auxiliary shutter 2 is operated in the closing direction to reduce the opening area. The outer skin material F can be set in accordance with the opened state, and the position of the outer skin material F can be adjusted so that the outer skin material F is in a predetermined position. As a result, variations in the shape and position displacement of the outer skin material are corrected in advance, and a more reliable molding process can be performed.

  Next, as shown in FIG. 27, the air is sucked from the air holes 34a of the retracting member 34 of the skin material forming means 3 and the lower surface of the central portion of the skin material F is adsorbed. Then, the upper holding means 5 is lowered and the edge of the outer skin material F is held on the shutter piece 10 of the shutter 1 by the pressing member 55. That is, the holding means 5 is lowered to bring the holding member 55 into contact with the edge portion of the outer skin material F, and the holding means 5 is further lowered to narrow the gap between the holding member 55 and the stay 57 and to move the coil spring 58. The pressing member 55 is pressed against the edge of the outer skin material F using the elastic force of the coil spring 58 and the outer skin material F is pressed and held on the shutter piece 10.

  Next, as shown in FIG. 28, the outer skin material forming means 3 is lowered while the center lower surface of the outer skin material F is attracted and held by the retracting member 34 while the edge of the outer skin material F is pressed and held by the presser member 55. Then, the retracting member 34 is retracted from the opening of the shutter 1, and the outer skin material F is drawn into the opening of the shutter 1 to form the outer skin material F in a bowl shape. At this time, the inner material G supplied in advance on the outer skin material F descends together with the central portion of the outer skin material F along with the eaves-like formation of the outer skin material, and is arranged inside the outer skin material F formed in the eaves-like shape. . In this way, when the outer skin material F is formed in a bowl shape, the edge of the outer skin material F is held by the holding means 5, so even if the outer skin material F is a foodstuff rich in elasticity such as bread dough, It can be formed in a bowl shape while extending the periphery of the edge, and even if the shape and size of the outer skin material is somewhat varied or misaligned, the outer skin material can be reliably formed in a bowl shape.

  Next, as shown in FIG. 29, the holding means 5 is raised, the pressing member 55 is separated from the edge of the outer skin material F, and the outer skin material forming means 3 is further lowered, whereby the hook-like outer skin material F is formed. The edge is positioned on the side surface of the shutter piece 10. The above is the arrangement process of arranging the inner material G on the outer skin material F.

  Then, as shown in FIGS. 30 and 31, the outer cover material F is attracted and held by the pull-in member 34, and the shutter 1 is closed as a sealing step, whereby the outer cover material is formed at the rear end portion 10c of the side surface of each shutter piece 10. The peripheral edge portion of F is collected and sealed so as to wrap the inner material, and the inner material G is wrapped with the outer skin material F by completely closing the rear end portions 10c of the shutter pieces 10 as shown in FIG. A molded product H is obtained. Thereafter, as shown in FIG. 33, while the molded product H is sucked and held by the retracting member 34, the tip of the retracting member 34 is inverted from upward to downward, and the molded product H is ejected from the retracting member 34 by blowing air from the air holes 34a. The product H is separated and placed on the conveyor 6, and the molded product H is conveyed by a belt.

  Thus, since the peripheral edge of the outer cover material is sealed by the rear edge 10c that is closed later than the front edge 10a of each shutter piece 10, as shown in FIGS. 30 and 31, the shutter piece 10 It is possible to seal the peripheral edge portion of the outer skin material F with the rear edge portion 10c in a state where the front edge portions 10a or the inclined surface portions 10b are closed, and the outer skin material has variation in shape and displacement, Even if the amount of the cloth at the peripheral edge of the outer skin material is slightly changed, the outer skin material does not protrude above the shutter 1 at the time of sealing, and the inner material can be surely wrapped and molded with the outer skin material.

  Further, the central portion of the outer skin material F is held by the retracting member 34 of the outer skin material forming means 3 that has entered the opening of the shutter 1, and the sheet-like outer skin can be simply retracted from the shutter opening. Since the material F can be formed in a bowl shape, it can be formed in a bowl shape with almost no damage to the outer skin material F, and a high-quality molded product can be obtained. Moreover, since the outer skin material F can be formed in a bowl shape without contacting the outer skin material forming means 3 and the inner material G on the outer skin material F, the inner material G adheres to the outer skin material forming means 3 and the inner material is filled. There is no risk of quantification being impaired or sanitary problems.

  Further, since the outer shell material F is held by adsorbing by the pull-in member 34 of the outer shell material forming means 3 and the molded product H is released by the blown air from the pull-in member 34, the molded product H is conveyed reliably and quickly. 6 is possible, and more stable high-speed operation is possible.

  In addition, the inner material G is previously disposed on the outer skin material F, and then the outer skin material is formed in a hook shape, but of course, the present invention is not limited to this, and after the outer skin material F is formed in a hook shape, The inner material G may be arranged inside the outer skin material F formed in a bowl shape.

  Further, as shown in FIGS. 34 to 38, as in the above-described modified examples (see FIGS. 21 to 24), the auxiliary shutter for adjusting the position of the outer skin material and the holding means for holding the edge of the outer skin material. May be simplified to simplify the device configuration and the molding process. In this case, as shown in FIGS. 35 and 36, the closing operation of the shutter 1 may be started while the retracting member 34 of the outer skin material forming means 3 is lowered to form the outer skin material F in a bowl shape. This makes it possible to move the shutter piece 10 along the inner material G when viewed with the inner material G as a reference. Thus, the inner material G can be wrapped and molded more smoothly.

  Further, as shown in FIGS. 34 to 37, a receiving member 7 made of a thin plate for receiving the outer skin material F is disposed above the shutter 1, and a circular shape is formed at the center of the receiving member 7 as shown in FIG. If the opening 70 is opened, the outer skin material F can be more stably placed on the receiving member 7 (see FIG. 34), and the outer skin material F is drawn into the opening 70 of the receiving member 7. Thus, the outer skin material F can be formed into a hook shape using the opening 70 (see FIG. 35).

[Embodiment]
With reference to FIGS. 39 to 47, the food wrapping and molding process of the food wrapping and molding apparatus of the present embodiment and the same apparatus will be described. 39 is a partial sectional front view of the food wrapping and forming apparatus, and FIGS. 40 to 47 are schematic side views of the food wrapping and forming process by the apparatus.

  In the food wrapping and forming apparatus, a receiving member 8 for receiving the outer skin material F is disposed below the shutter 1, and the auxiliary shutter for adjusting the position of the outer skin material and the shutter driving means of the auxiliary shutter are omitted. The main feature is that the configuration is simplified, and the other configurations are substantially the same as those of the first reference example described above.

  39 and 40, the receiving member 8 is fixed below the shutter piece 10 of the shutter 1, and a circular opening 80 is formed at the center thereof. Hereinafter, the food wrapping and forming process by the food wrapping and forming apparatus will be described with reference to FIGS.

  First, as shown in FIG. 40, the sheet-like outer skin material F is supplied onto the receiving member 8 with the shutter 1 opened. At this time, by operating the shutter piece 10 of the shutter 1 in the closing direction to reduce the opening area, the outer skin material F can be set in accordance with the reduced opening state, and the outer skin material F is placed in a predetermined position. Thus, the position adjustment of the outer skin material F can be performed. As a result, variations in the shape and position displacement of the skin material are corrected in advance, and a more reliable molding process can be performed.

  Next, as shown in FIG. 41, the pushing member 30 of the upper skin material forming means 3 is lowered to hold the edge of the skin material F on the receiving member 8 by the pressing member 50 of the holding means 5. That is, the holding means 5 is lowered together with the pushing member 30 to bring the holding member 50 into contact with the edge of the outer skin material F, and the holding means 5 is further lowered to narrow the gap between the holding member 50 and the stay 52. The coil spring 53 is compressed, and the holding member 50 is pressed against the edge of the outer skin material F by using the elastic force of the coil spring 53 to hold the outer skin material F on the receiving member 8.

  Then, as shown in FIG. 42, with the holding member 50 holding the edge portion of the outer skin material F, the pressing member 30 is further lowered to cause the pressing member 30 to enter the opening 80 of the receiving member 8, and the sheet The outer skin material F is formed in a bowl shape by pushing the central portion of the outer skin material F into the opening 80 of the member 8. In this way, since the edge of the skin material F is held by the holding means 5 when the skin material F is formed in a bowl shape, even if the skin material F is an elastic food material such as bread dough, the edge of the skin material F It can be formed into a bowl shape while extending the periphery of the part, and even if the shape and size of the outer skin material is somewhat varied or misaligned, the outer skin material can be reliably formed into a bowl shape. At this time, if the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material from extending downward more than necessary.

  Next, as shown in FIG. 43, while the pushing member 30 is raised, the valve 40 in the pushing member 30 is raised to open the discharge hole, thereby discharging the inner material G. The inner material G is arranged inside. Then, when a predetermined amount of the inner material G is discharged, the valve 40 is lowered to close the discharge hole. Thus, since the inner member G is supplied through the pushing member 30 at the same time that the pushing member 30 is raised, it is possible to prevent the outer skin material F made of bread dough from contracting as the pushing member 30 rises. At the same time, it is possible to efficiently form the outer skin material F and supply the inner material G in a short time. At this time, since the outer skin material F is supported by the support member 60, it is possible to prevent the outer skin material F from being unnecessarily stretched due to the discharge of the inner material G, and the inner material G is reliably placed inside the outer skin material F. Can be arranged.

  Next, as shown in FIG. 44, the push-in member 30 is further raised to separate the presser member 50 from the edge of the outer skin material F. The above is the arrangement process of arranging the inner material G on the outer skin material F.

  Then, as a sealing step by the shutter 1, as shown in FIGS. 45 and 46, the shutter 1 is closed in a state where the outer skin material F is supported by the support member 60, thereby rear end portions of the side surfaces of the shutter pieces 10. The outer peripheral material F is gathered and sealed so as to wrap the inner material at 10c, and the inner end G of the outer shell material F is closed by completely closing the rear end portions 10c of the shutter pieces 10 as shown in FIG. To obtain a molded product H enclosing Thereafter, the support member 60 that supports the molded product H is lowered to place the molded product H on the belt, and the belt conveyor 63 is driven to convey the molded product H to the belt.

  As described above, since the peripheral edge portion of the outer skin material is sealed by the rear edge portion 10c that is closed later than the front edge portion 10a of each shutter piece 10, as shown in FIGS. 45 and 46, the shutter piece 10 It is possible to seal the peripheral edge portion of the outer skin material F with the rear edge portion 10c in a state where the front edge portions 10a or the inclined surface portions 10b are closed, and the outer skin material has variation in shape and displacement, Even if the amount of the cloth at the peripheral edge of the outer skin material is slightly changed, the outer skin material does not protrude above the shutter 1 at the time of sealing, and the inner material can be surely wrapped and molded with the outer skin material.

  Further, since the outer skin material F is supplied onto the receiving member 8 provided below the shutter 1, the outer skin material F can be placed more stably (see FIG. 40). The outer skin material F can be reliably pressed and held by the holding member 50 of the holding means 5 (see FIG. 41), and the pushing member 30 is advanced into the opening 80 of the receiving member 8 so that the receiving member 8 It is also possible to form the outer skin material F in a hook shape using the opening 80 (see FIG. 42).

  Further, since the outer skin material F is supplied onto the receiving member 8 provided below the shutter 1, the position of the outer skin material F on the receiving member 8 can be adjusted by the closing operation of the shutter 1, and the apparatus configuration can be adjusted. It can be greatly simplified.

[Third reference example]
With reference to FIGS. 48 to 56, the food wrapping and molding process of the third embodiment will be described. 48 is a partial sectional front view of the food wrapping and forming apparatus, and FIGS. 49 to 56 are schematic side views of the food wrapping and forming process by the apparatus.

  As in the second reference example described above, the food wrapping and forming apparatus uses the outer skin material F as an opening instead of the pushing member 30 in the first reference example, as the outer skin material forming means 3 for forming the outer skin material F in a bowl shape. A pull-in member 34 that forms a bowl shape by being pulled in is employed, and, similarly to the above-described embodiment, a receiving member 8 for receiving the outer skin material F is disposed below the shutter 1 to assist in adjusting the position of the outer skin material. The main feature is that the apparatus configuration is simplified by omitting the shutter and the shutter driving means of the auxiliary shutter. Hereinafter, the food wrapping and forming process by the food wrapping and forming apparatus will be described with reference to FIGS. 49 to 56.

  First, as shown in FIG. 49, a sheet-like outer skin material F is placed on the receiving member 8 with the shutter 1 opened. On the outer skin material F, an inner material G is arranged in advance by an inner material supply means (not shown). At this time, the retracting member 34 of the outer skin material forming means 3 is raised to enter the opening 80 of the receiving member 8 in advance, and the outer skin material F is supplied onto the retracting member 34 and the receiving member 8. By doing so, the outer skin material F can be placed more stably. Then, when the shutter piece 10 of the shutter 1 is operated in the closing direction to reduce the opening area, the outer skin material F can be set in accordance with the reduced opening state so that the outer skin material F is placed in a predetermined position. In addition, the position of the outer skin material F can be adjusted. As a result, variations in the shape and position displacement of the skin material are corrected in advance, and a more reliable molding process can be performed.

  Next, as shown in FIG. 50, air is sucked from the air holes 34a of the retracting member 34 of the skin material forming means 3 and the lower surface of the central portion of the skin material F is adsorbed. Then, the upper holding means 5 is lowered and the edge of the outer skin material F is received and held on the member 8 by the pressing member 55. That is, the holding means 5 is lowered to bring the holding member 55 into contact with the edge portion of the outer skin material F, and the holding means 5 is further lowered to narrow the gap between the holding member 55 and the stay 57 and to move the coil spring 58. The holding member 55 is pressed against the edge of the outer skin material F by using the elastic force of the coil spring 58 and is held on the receiving member 8 by receiving the outer skin material F.

  Next, as shown in FIG. 51, the outer skin material forming means 3 is lowered while the center lower surface of the outer skin material F is attracted and held by the pulling member 34 while the edge of the outer skin material F is pressed and held by the presser member 55. Then, the retracting member 34 is withdrawn from the opening 80 of the receiving member 8, and the outer skin material F is drawn into the opening 80 of the receiving member 8 to form the outer covering material F in a bowl shape. At this time, the inner material G supplied in advance on the outer skin material F descends together with the central portion of the outer skin material F along with the eaves-like formation of the outer skin material, and is arranged inside the outer skin material F formed in the eaves-like shape. . In this way, when the outer skin material F is formed in a bowl shape, the edge of the outer skin material F is held by the holding means 5, so even if the outer skin material F is an elastic food such as bread dough, the edge of the outer skin material F It can be formed into a bowl shape while extending the periphery of the part, and even if the shape and size of the outer skin material is somewhat varied or misaligned, the outer skin material can be reliably formed into a bowl shape.

  Next, as shown in FIG. 52, the holding means 5 is raised and the presser member 55 is separated from the edge of the outer skin material F. The above is the arrangement process of arranging the inner material G on the outer skin material F.

  Then, as shown in FIGS. 53 and 54, the outer shell material F is attracted and held by the pull-in member 34, and the shutter 1 is closed as a sealing process, whereby the outer shell material is formed at the rear end portion 10c of the side surface of each shutter piece 10. The peripheral portion of F is collected and sealed so as to wrap the inner material, and the inner material G is wrapped with the outer skin material F by completely closing the rear end portions 10c of the shutter pieces 10 as shown in FIG. A molded product H is obtained. Thereafter, as shown in FIG. 56, while the molded product H is sucked and held by the retracting member 34, the tip of the retracting member 34 is inverted from the upward direction to the downward direction, and the molded product H is ejected from the retracting member 34 by blowing air from the air holes 34a. The product H is separated and placed on the conveyor 6, and the molded product H is conveyed by a belt.

  Thus, since the peripheral edge of the outer cover material is sealed by the rear edge 10c that is closed later than the front edge 10a of each shutter piece 10, as shown in FIGS. 53 and 54, the shutter piece 10 It is possible to seal the peripheral edge portion of the outer skin material F with the rear edge portion 10c in a state where the front edge portions 10a or the inclined surface portions 10b are closed, and the outer skin material has variation in shape and displacement, Even if the amount of the cloth at the peripheral edge of the outer skin material is slightly changed, the outer skin material does not protrude above the shutter 1 at the time of sealing, and the inner material can be surely wrapped and molded with the outer skin material.

  The central portion of the outer skin material F is held by the retracting member 34 of the outer skin material forming means 3 that has entered the opening 80 of the receiving member 8, and the retracting member 34 is retreated from the circular opening 80 of the receiving member 8. The sheet-like outer skin material F can be easily and reliably formed into a hook-like shape simply by making it possible to form a hook-like shape with almost no damage to the outer skin material F, resulting in a high-quality molded product. Obtainable. Moreover, since the outer skin material F can be formed in a bowl shape without contacting the outer skin material forming means 3 and the inner material G on the outer skin material F, the inner material G adheres to the outer skin material forming means 3 and the inner material is filled. There is no risk of quantification being impaired or sanitary problems.

  Further, since the outer shell material F is held by adsorbing by the pull-in member 34 of the outer shell material forming means 3 and the molded product H is released by the blown air from the pull-in member 34, the molded product H is conveyed reliably and quickly. 6 is possible, and more stable high-speed operation is possible.

  Further, since the outer skin material F is supplied onto the receiving member 8 provided below the shutter 1, the outer skin material F can be placed more stably (see FIG. 49). The outer skin material F can be securely held by the holding member 50 of the holding means 5 (see FIG. 50).

  Further, since the outer skin material F is supplied onto the receiving member 8 provided below the shutter 1, the position of the outer skin material F on the receiving member 8 can be adjusted by the closing operation of the shutter 1, and the first described above. It is not necessary to provide an auxiliary shutter and shutter driving means for the auxiliary shutter in one embodiment, and the apparatus configuration can be greatly simplified.

  In addition, the inner material G is previously disposed on the outer skin material F, and then the outer skin material is formed in a hook shape, but of course, the present invention is not limited to this, and after the outer skin material F is formed in a hook shape, The inner material G may be arranged inside the outer skin material F formed in a bowl shape.

  In the above embodiment, four shutter pieces 10 that reciprocally swing around the drive shaft are used as the shutter 1, but the front edge portion that is closed first by the closing operation of the shutter on the side surface of each shutter piece and the shutter piece 10. The number and shape of the shutter pieces are not particularly limited as long as a rear edge portion that is closed later than the front edge portion is formed and the outer skin material can be sealed at the rear edge portion. For example, as shown in FIG. 57, front and rear edge portions 15a and 15c are provided on the side surfaces of six shutter pieces 15, and the shutter pieces 15 are opened and closed by sliding linearly in the direction of the arrows. As shown in FIGS. 58 (a) and 58 (b), a front edge portion 16a and a rear edge portion 16c are provided on the side surfaces of the six shutter pieces 16, respectively. Using a shutter mechanism that opens and closes by swinging while linearly moving in accordance with the rotational movement in the direction of the arrow, using a shutter mechanism that opens and closes by rotating each shutter piece continuously, and various shutter mechanisms Can be adopted.
