[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food wrapping and forming apparatus, and more particularly to a food wrapping and forming apparatus 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. is there.
[0002]
[Prior art]
Conventionally, as a technology related to food molding that wraps the inner material such as rice cake, cooked meat and vegetables 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 made into a cylindrical shape continuously It is formed in a conventional manner, and this is squeezed and cut by opening / closing operation of a shutter mechanism (for example, Japanese Utility Model Publication No. 63-29433). However, when fermenting dough such as bread dough is used as the skin material, excessive pressure or twisting is applied to the dough when forming the tube, so 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.
[0003]
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, in Japanese Patent Laid-Open No. 2000-50854, 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 the inner material is supplied into the outer packaging material formed in this bowl shape. After that, it is described that the upper edge portion of the outer packaging material is squeezed with a shutter composed of a plurality of shutter pieces to seal the upper edge portion of the outer packaging material and wrap and mold the inner material.
[0004]
[Problems to be solved by the invention]
However, in this conventional food molding method, since wrapping molding is performed using a cup-shaped female mold, a molded food having a size corresponding to the cup-shaped female mold can be obtained. Molded foods larger than the volume of the female mold cannot be obtained, and when the sheet-like skin material is supplied to the upper surface of the female mold, if the skin material falls into the female mold, the subsequent process is performed. Since it becomes impossible to seal the outer skin material well, adjustments and changes related to the size, thickness, etc. of the sheet-like outer skin material to be supplied, and characteristics such as flexibility, adhesiveness, etc. were limited to a narrow range. However, there is a problem that it is not possible to sufficiently respond to requests for changing the size of the molded food or changing the ratio of the outer shell material to the inner material of the molded food.
[0005]
The present invention was made in view of the above-mentioned difficulties in conventional food molding technology, and the shape, thickness and other shapes of the skin material, and the properties such as flexibility and adhesiveness change. However, this outer skin material can be stably supplied to the molding part, the inner material can be securely wrapped and molded with the outer skin material, the size of the molded food can be changed, and the ratio between the outer skin material and the inner material can be changed.

[0019]
Hereinafter, the food wrapping and forming process by the food wrapping and forming apparatus of the first embodiment will be described with reference to FIGS. In the present embodiment, an example in which bread dough is used as the outer skin material F and straw is used as the inner material G will be described.
[0020]
First, as shown in FIG. 5, the sheet-like outer skin material F is supplied to the upper surface of the receiving member 2 with the shutter 1 opened. The shape of the outer skin material F is extended by a roller and has an elliptical shape. At this time, since the guide 3 is disposed on the inner peripheral edge of the opening 20 of the receiving member 2, there is no fear that the supplied sheet-like outer skin material F falls into the opening 20, and the outer skin material F is stably provided. The receiving member 2 can be supplied and placed. Then, after placing the outer skin material F on the receiving member 2, if the opening area is reduced by operating the shutter piece 10 of the shutter 1 in the closing direction, 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 shift of the outer skin material are corrected in advance, and a more reliable molding process can be performed.
[0021]
Next, as shown in FIG. 6, the edge of the outer skin material F is held on the member 2 by the pressing member 60 of the holding means 6 by lowering the pressing member 40 of the upper pressing means 4. That is, the holding means 6 is lowered together with the pushing member 40 to bring the holding member 60 into contact with the edge of the outer skin material F, and the holding means 6 is further lowered to narrow the gap between the holding member 60 and the stay 62. The coil spring 63 is compressed, and the holding member 60 is pressed against the edge of the outer skin material F using the elastic force of the coil spring 63 to hold the outer skin material F on the receiving member 2.
[0022]
Then, as shown in FIG. 7, with the holding member 60 holding the edge portion of the outer skin material F, the pressing member 40 is further lowered to cause the pressing member 40 to enter the opening 20 of the member 2, and 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 20 of the member 2. As described above, in this embodiment, when the outer skin material F is formed in a bowl shape, since the edge of the outer skin material F is held by the holding means 6, even if the outer skin material F is an elastic food material such as bread dough, It can be formed in a bowl shape while extending around the edge of the outer skin material F. Even if the shape and size of the outer skin material varies or is misaligned, the outer skin material is reliably formed in a bowl shape. be able to. Further, when the outer skin material is formed in a bowl shape, the elastically deformable guide 3 is bent downward by the lowering of the pushing member 40 and can support the side surface of the outer skin material F formed in the hook shape by its elastic repulsive force. At this time, if the outer skin material F is supported by the support member 70, the outer skin material can be prevented from extending more than necessary.
[0023]
Next, as shown in FIG. 8, the valve 50 in the push-in member 40 is raised while the push-in member 40 is lifted to open the discharge hole, thereby discharging the inner material G, and the inner side of the outer skin material F formed in a bowl shape. The inner material G is disposed on the surface. Then, when a predetermined amount of the inner material G is discharged, the valve 50 is lowered to close the discharge hole. As described above, in this embodiment, the pushing member 40 is raised and the inner material G is supplied through the pushing member 40, and the side surface of the outer skin material F is supported by the elastic repulsive force of the guide 3 which is bent and deformed. Therefore, it is possible to prevent the outer skin material F made of bread dough from contracting as the push-in member 40 is raised, and to efficiently form the outer skin material F and supply the inner material G in a short time. Is possible. At this time, the outer skin material F is supported by the support member 70, and the side surface of the outer skin material F is supported by the guide 3, so that the outer skin material F is prevented from being unnecessarily stretched by the discharge of the inner material G. The inner material G can be reliably disposed inside the outer skin material F.
[0024]
Next, as shown in FIG. 9, the push-in member 40 is further raised to separate the presser member 60 from the edge of the outer skin material F. Then, as shown in FIGS. 10 and 11, by closing the shutter 1, the peripheral portions of the outer skin material F on the receiving member 2 are collected so as to wrap the inner material G, and the peripheral portions of the collected outer skin material F are collected. By sealing, a molded product H in which the inner material G is wrapped with the outer skin material F is obtained. Thereafter, the shutter 1 is opened, the support member 70 that supports the molded product H is lowered, the molded product H is placed on the belt, the belt conveyor 73 is driven, and the molded product H is conveyed by the belt.
[0025]
As described above, according to the present embodiment, when the sheet-like outer skin material F is supplied to the upper surface of the receiving member 2, the guide 3 disposed on the inner peripheral edge of the opening 20 of the receiving member 2 stabilizes the outer skin material F. For example, even if the size or thickness of the sheet-like skin material to be supplied is changed for changing the size of the molded product H or changing the ratio between the skin material F and the inner material G, this sheet-like skin There is no fear that the material falls into the opening 20 of the receiving member 2, and the enveloping can be reliably performed in the subsequent steps.
[0026]
Further, according to the present embodiment, the guide 3 disposed in the opening 20 of the receiving member 2 is elastically deformed, and therefore, as shown in FIG. When supplied, the outer diameter of the swelled skin material F can be allowed to be larger than the diameter of the opening 20 of the receiving member 2, and the size of the molded product H is limited to the diameter of the opening 20 of the receiving member 2. Without limitation, the size of the molded product H can be changed as appropriate.
[0027]
In the present embodiment, the inner material G is disposed inside the outer skin material F after the outer skin material is formed in a bowl shape. For example, the inner material G is previously placed on the outer skin material F. In this state, the outer skin material F is supplied onto the receiving member 2, and the outer skin material F is pushed into the opening of the shutter 1 together with the inner material G by the pushing member 40, so that the outer skin material F is formed in a bowl shape. . Thus, even if the inner material G is previously placed on the outer skin material F and supplied onto the receiving member 2, the guide 3 is disposed on the inner peripheral edge of the opening 20, so that the outer skin material is stabilized. Can be placed.
[0028]
In the present embodiment, the guide 3 made of a thin plate material having a circular hole 30 in the center is used. However, the present invention is of course not limited to this. For example, the guide 3 is formed in the circular hole 30 of the guide 3. Radial cuts can be formed, or the guide 3 can be made thinner as the thickness of the guide 3 increases, and various design changes can be made in consideration of the elastic repulsive force of the guide 3 and the like. In this way, by appropriately selecting the guide 3 having an appropriate elastic repulsive force, for example, when collecting and sealing the peripheral portion of the outer skin material with the shutter 1, the elastic repulsive force of the guide 3 is used. It is also possible to collect the peripheral edge portion of the outer skin material, which makes it possible to more reliably enclose and form the food.
[0029]
Furthermore, in this embodiment, the edge of the outer skin material F is received on the member 2 by the holding means 6 and the outer skin material F is formed in a bowl shape. However, as shown in FIGS. It is also possible to omit the holding means, which can simplify the apparatus configuration and the molding process. In this embodiment, the support means 7 for supporting the outer skin material F and the molded product H is configured such that the support member 70 is plate-shaped and the belt of the belt conveyor 73 is moved up and down. You may make it move.
[0030]

[0032]
As shown in FIG. 16, the retracting means 8 of the present embodiment includes a tubular retracting member 81 whose base side is supported by a stay 82 fixed to an elevator base 83 and whose distal end is bent at a right angle, and the distal end of the retracting member 81 is A pinion-rack mechanism 84 for rotating the base of the retracting member 81 for rotation, an air cylinder (not shown) for linearly reciprocating the rack of the pinion-rack mechanism 84, and for raising and lowering the elevator table 83 up and down The feed screw mechanism 85 and a motor 86 for driving the male screw of the feed screw mechanism 85 are configured. By controlling the rotation direction, rotation angle, etc. of the motor 86, the tip of the pull-in member 81 is moved up and down appropriately, and the pinion-rack mechanism 84 is driven by an air cylinder so that the tip of the pull-in member 81 is turned upward from time to time. Flip downward.
[0033]
Further, as shown in FIG. 17, the retracting member 81 of the retracting means 8 has a plurality of vent holes 80, 80,... At the tip, and an intake / exhaust device (not shown) is connected to the base end.

By lowering the stay 62, the holding member 60 The edge of the outer skin material on the receiving member 2 is pressed and held.
[0035]
Further, in FIG. 16, what is indicated by reference numeral 7 is a belt conveyor disposed below the drawing-in means 8, and conveys the molded product H separated from the drawing-in member 81 of the drawing-in means 8 by belt forming. (See Figure 23).
[0036]
Hereinafter, the food wrapping molding process by the food wrapping molding apparatus of the second embodiment will be described with reference to FIGS.
[0037]
First, as shown in FIG. 17, the receiving member 2 and the drawing member 81 are opened in a state where the shutter 1 is opened and the drawing member 81 of the drawing means 8 is lifted and entered into the opening 20 of the receiving member 2 in advance. A sheet-like skin material F is placed on top. The shape of the outer skin material F is elongated by a roller and has an elliptical shape, and the inner material G is arranged on the outer skin material F in advance by an inner material supply means (not shown). Thus, in this embodiment, since the outer skin material F can be placed on the receiving member 2 and the retracting member 81, the supplied sheet-like outer skin material F may fall into the opening 20 of the receiving member 2. Therefore, the outer skin material F can be supplied and placed stably. As in the first embodiment, after the skin material F is supplied and placed, the shutter material 10 of the shutter 1 is operated in the closing direction to reduce the opening area, so that the skin material is adapted to the reduced opening state. 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 positional deviation of the skin material are corrected in advance, and a more reliable molding process can be performed.
[0038]
Next, as shown in FIG. 18, air is sucked from the vent hole 80 of the retracting member 81 of the retracting means 8 and the lower surface of the central portion of the outer skin material F is adsorbed. Then, the upper holding means 6 is lowered and the holding member 60 holds the edge portion of the outer skin material F on the member 2. That is, the holding means 6 is lowered to bring the holding member 60 into contact with the edge portion of the outer skin material F, and the holding means 6 is further lowered to narrow the gap between the holding member 60 and the stay 62 and to move the coil spring 63. The pressing member 60 is pressed against the edge of the outer skin material F by using the elastic force of the coil spring 63 and the outer skin material F is received and held by the member 2.
[0039]
Next, as shown in FIG. 19, with the holding member 60 holding the edge of the outer skin material F, the lower surface of the outer skin material F is attracted and held by the pulling member 81, and the drawing means 8 is lowered and drawn. The member 81 is retracted from the opening 20 of the member 2 and the outer skin material F is drawn into the opening 20 of the member 2 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. . Thus, also in this embodiment, since the edge part of the outer skin material F is hold | maintained by the holding means 6 when forming the outer skin material F in bowl shape, even if the outer skin material F is a foodstuff rich in elasticity, such as bread dough, It can be formed into a bowl shape while stretching the periphery of the outer edge of the outer skin material F. Even if the shape and size of the outer skin material varies or is misaligned, the outer skin material is reliably formed into a bowl shape. can do.
[0040]
Next, as shown in FIG. 20, the holding means 6 is raised and the pressing member 60 is separated from the edge of the outer skin material F. Then, as shown in FIG. 20 and FIG. 21, the peripheral portion of the outer skin material F on the receiving member 2 is collected so as to wrap the inner material G by closing the shutter 1, and the peripheral edge portion of the collected outer skin material F is collected. Sealing is performed and the shutter 1 is completely closed as shown in FIG. 22 to obtain a molded product H in which the inner material G is wrapped with the outer skin material F. Thereafter, as shown in FIG. 23, while the molded product H is sucked and held by the retracting member 81, the leading end of the retracting member 81 is inverted from upward to downward, and the molded product H is blown from the air holes 80 to thereby draw the molded product H. The molded product H is placed on the conveyor 7 and conveyed by a belt.
[0041]
As described above, according to the present embodiment, when the outer skin material F is supplied, the retracting member 81 that has previously entered the opening 20 of the receiving member 2 stably supports the outer skin material F. Even if the size or thickness of the sheet-like outer shell material to be supplied is changed for changing the size of H or changing the ratio of the outer shell material F and the inner material G, the sheet-like outer skin material will still open the opening 20 of the receiving member 2. Therefore, it is possible to reliably perform the wrapping molding in the subsequent steps.
[0042]
Further, according to the present embodiment, as shown in FIG. 21, when the outer skin material is sealed, the outer diameter of the expanded outer skin material F can be allowed to be larger than the diameter of the opening 20 of the receiving member 2. The size of the molded product H is not limited to the diameter of the opening 20 of the receiving member 2, and the size of the molded product H can be changed as appropriate.
[0043]
Further, according to the present embodiment, the central portion of the outer skin material F is held by the retracting member 81 of the retracting means 8 that has entered the opening of the shutter 1, and the retracting member 81 is retracted from the opening 20 of the member 2. Since the sheet-like outer skin material F can be easily formed into a hook shape simply by making it, the hook-like shape can be formed almost without damaging 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 bringing the pulling means 8 into contact with the inner material G on the outer skin material F, the filling quantitativeness of the inner material is impaired, or a sanitary problem is caused. There is no fear.
[0044]
Further, according to the present embodiment, the outer cover material F is held by being attracted by the retracting member 81 of the retracting means 8, and the molded product H is released by the air blown from the retracting member 81. It can be transferred to the conveyor 7 reliably and quickly, and more stable high-speed operation is possible.
[0045]
In this embodiment, the inner material G is arranged on the outer skin material F in advance, and then the outer skin material is formed in a bowl shape. However, the present invention is not limited to this, and the outer skin material F is After forming the inner shape, the inner material G may be arranged inside the outer skin material F formed in a bowl shape.
[0046]
Further, in this embodiment, the edge of the outer skin material F is held on the member 2 by the holding means 6 and the outer skin material F is formed in a bowl shape. However, as shown in FIGS. It is also possible to omit the means, which can simplify the apparatus configuration and the molding process.
[0047]
The specific examples of the food wrapping and forming apparatus of the present invention have been described above with the first embodiment and the second embodiment, but the present invention is of course not limited to these embodiments, and is within the scope of the claims. Various design changes are possible.
[0048]
For example, in the above-described embodiment, four shutter pieces 10 that reciprocally swing around the drive shaft are used as the shutter 1, but if the outer skin material can be sealed, the number of shutter pieces, The shape is not particularly limited. For example, as shown in FIG. 28, a shutter mechanism that opens and closes when the six shutter pieces 15 slide linearly in the direction of the arrows can be used. Alternatively, as shown in FIGS. A shutter mechanism that opens and closes when the single shutter piece 16 swings while linearly moving in accordance with the rotational movement of the action pin 17 in the direction of the arrow, or a shutter mechanism that opens and closes as each shutter piece rotates continuously Or various shutter mechanisms can be employed.
