  When rolling into a thin circular plate like pizza dough, it is ideal to form a dough divided into a predetermined amount into a round shape and roll it radially from the center, but in reality they are orthogonal to each other It is common to roll in two directions. In particular, in the case of a highly viscous dough such as pizza dough, rolling in only one direction causes the rolling to work unevenly, so that the rolled portion shrinks when the dough is baked and the shape collapses.

  FIG. 21 is an explanatory view showing an example of a conventional process for rolling in two directions orthogonal to each other. In this example, rolling is performed using two rolling rollers 100 and 101. The dough A, which has been divided into a predetermined amount and rounded, is rolled by the rolling roller 100 so as to be stretched in the conveying direction (fabric B), rotated 90 degrees by the direction rotating conveyor (dough C), and rolled by the rolling roller 101. Rolled to be stretched (Dough D). Thus, it rolls to a circular thin plate shape by rolling in two directions orthogonal to each other using two rolling rollers.

  FIG. 22 is an explanatory view showing another example of the conventional process. In this example, rolling is performed using rolling mechanisms 102 and 103 in which a plurality of rod-shaped rolling members as shown in Patent Document 1 are arranged in parallel. Also in this example, after the dough A is rolled in the transport direction by the rolling mechanism 102 (the dough B), it is transported to the belt conveyor whose direction of the transport direction is changed by 90 degrees (the dough C) and rolled by the rolling mechanism 103 and orthogonal to each other. Rolling in two directions.

  As described above, in a rolling mechanism using a rolling roller or a pressing member conventionally used for rolling, when rolling into a circular thin plate, there are two apparatuses for rolling in two directions orthogonal to each other. It is necessary to install a transport mechanism for rotating the dough. Therefore, the equipment for rolling becomes complicated, and the necessary space and cost burden must be increased.

  In addition, although the entire dough A is pressed and rolled at once with a pressing plate, shrinkage of the dough is unavoidable after rolling, and the shape of the dough tends to collapse.

  Therefore, an object of the present invention is to provide a dough rolling apparatus capable of stably rolling a dough into a thin plate shape with a compact apparatus configuration.

The dough rolling apparatus according to the present invention includes a conveying means for conveying the dough divided into a predetermined amount, and an action line set in a direction shifted by a predetermined angle with respect to the dough conveying direction. A first rolling means having a plurality of first rolling members to be pressed and a plurality of second rolling members which are respectively disposed between the first rolling members and press the dough along the action line. Two rolling means, and a drive means for alternately rolling the first rolling means and the second rolling means, and the working area where the rolling action is performed by the first and second rolling members is substantially rectangular. It is formed and the conveyance path | route of the said cloth | dough is set along the diagonal of the said rectangle . Further, the first and second rolling members roll the dough in a direction along the first rolling surface and / or the action line formed so as to roll the dough in a direction substantially orthogonal to the action line. It has the 2nd rolling surface formed so that it may do. Furthermore, at least one of the first and second rolling members is characterized in that the first rolling surface is formed on the entire pressing surface. Further, at least one of the first and second rolling members is characterized in that the first rolling surface is formed on at least one surface of the plurality of protrusions arranged along the action line. And Further, at least one of the first and second rolling members is characterized in that the second rolling surface is formed on at least one surface of a plurality of protrusions arranged along the action line. And Further, the first rolling surface is a columnar curved surface formed along the action line, and the second rolling surface is a columnar curved surface formed along a direction substantially perpendicular to the action line. Features.

  By having the above configuration, the same portion of the dough is alternately rolled a plurality of times by the first rolling member and the second rolling member while conveying the dough, so that a sufficient rolling action is given to the dough Shrinkage after rolling is suppressed. Therefore, the rolled shape is maintained without breaking even when the dough is fired.

  Moreover, since it is such a simple apparatus structure, it is not necessary to provide two rolling apparatuses like the prior art shown in FIG.21 and FIG.22, and additional facilities, such as a direction change conveyor, are unnecessary, and it is in a process. The necessary lines can be shortened, and the apparatus can be made more compact than in the past.

  Then, by setting the action line in a direction shifted by a predetermined angle with respect to the conveyance direction of the dough, the rolling direction of the first rolling member and the second rolling member is shifted from the conveyance direction with respect to the dough being conveyed. A uniform rolling operation is performed. For example, in the case of circular dough, the rolling direction is the same when rolling in the direction perpendicular to the working line and the direction along the working line by shifting the working line by approximately 45 degrees with respect to the conveying direction. It is shifted by 45 degrees with respect to the conveyance direction, and the influence of the conveyance of the dough is almost equal and extends in both rolling directions, so that a uniform rolling operation can be realized. Further, if the shift angle can be finely adjusted while checking the shape of the dough after rolling, the shape of the dough can be finely adjusted.

  In addition, the working area where the rolling operation is performed by the first and second rolling members is formed in a substantially rectangular shape, and the dough rolling is performed from the corner of the working area by setting the conveying path of the dough along the diagonal of the rectangle. The operation starts, and the rolling range is gradually expanded according to the conveyance movement of the dough, so that the dough can be smoothly rolled.

  Further, the first and second rolling members are formed so as to roll the dough in a direction along the first rolling surface and / or the action line formed so as to roll the dough in a direction substantially orthogonal to the action line. By having the second rolling surface, rolling is performed in two directions orthogonal to each other, so that the portion is rolled so as to expand substantially uniformly, and the thin plate is formed so as to uniformly expand the entire dough. It can be rolled into a shape. Therefore, if the dough before rolling is formed in a circle, it becomes possible to roll into a thin plate-like dough having substantially the same circular shape and a substantially uniform thickness, which is suitable for rolling pizza dough, etc. .

  Then, at least one of the first and second rolling members is formed on the entire pressing surface, or the first rolling surface is formed on at least one surface of the plurality of protrusions arranged along the action line. By forming the rolling surface or the second rolling surface, the pressing surfaces of the first and second rolling members can be appropriately combined with the first rolling surface and the second rolling surface according to characteristics such as the hardness of the dough. It can comprise and can set so that the optimal rolling effect may be exhibited.

  Further, the first rolling surface is formed into a columnar curved surface along the action line, and the second rolling surface is formed into a columnar curved surface along a direction substantially orthogonal to the action line, so that the rolling operation of each rolling surface is uniform. A pressing force can be applied to the dough.

Bearing bodies 46 and 47 project horizontally from the housing 45 of the drive mechanism 4, and support shafts 50 a and 60 a are inserted into the bearing holes bored in the bearing body 46 so as to be vertically movable. The support shafts 50b and 60b are inserted into the bearing holes formed in the bearing body 47 so as to be movable up and down.

  A pair of support shafts 50a and 50b is horizontally attached with a connecting bar 51 for connecting and fixing the two, and a pair of support shafts 60a and 60b is attached with a connecting bar 61 for connecting and fixing both horizontally.

Thus, when the attachment position 53a is located at the top, the attachment position 63a is located at the bottom. Therefore, when the support shafts 50a and 50b are raised, the support shafts 60a and 60b are lowered, and when the support shafts 50a and 50b are lowered, the support shafts 60a and 60b are raised, and the two support shafts are alternately moved up and down. To do.

  3 shows a perspective view of the first rolling mechanism 5 and the second rolling mechanism 6, FIG. 4 is an exploded perspective view of the first rolling mechanism 5, and FIG. 5 is an exploded perspective view of the second rolling mechanism 6. Is shown.

  A rod-like support member 54 disposed along the conveyance direction D of the fabric f is fixed to the lower ends of the pair of support shafts 50a and 50b. Further, a rod-like support member 64 disposed along the conveyance direction D of the fabric f is fixed to the lower ends of the pair of support shafts 60a and 60b.

  As shown in FIG. 4, three rectangular support plates 55 a to 55 c are suspended from the lower surface of the support member 54 at equal intervals in an oblique direction shifted by a predetermined angle with respect to the transport direction D. And the mounting members 56a-56c of L-shaped cross section are being fixed to the lower part of each support plate with the screw | thread etc. FIG. Each mounting member is fixed to each support plate so that its longitudinal direction matches the mounting direction of each support plate. Further, as will be described later, the support plate 55a is positioned at the upstream end position in the transport direction D of the mounting member 56a, and the support plate 55b is mounted on the mounting member so that the mounting members 56a to 56c are aligned in the operation region. The support plate 55c is attached to the downstream end position of the mounting member 56c in the transport direction D at the center position of 56b.

  The first rolling members 57a to 57c are fixed to the lower surfaces of the mounting members 56a to 56c with screws or the like with their upper surfaces in close contact with each other. Each first rolling member is formed in the same shape, and the upper surface is formed in a plane and the lower surface is formed in a curved surface. FIG. 6 shows a side view of the first rolled member (FIG. 6 (a)) and an E-EA cross-sectional view (FIG. 6 (b)). In addition, the first rolling surface P1 is formed in a curved shape of an axial semicircular column along the longitudinal direction.

  As shown in FIG. 5, the second rolling mechanism 6 also has the same configuration as that of the first rolling mechanism 5, and three support plates 65 a to 65 c are suspended at equal intervals on the lower surface of the support member 64. Mounting members 66a to 66c having an L-shaped cross section are fixed to each support plate. And the 2nd rolling members 67a-67c are being fixed to the lower surface of each mounting member. The attachment of each member is the same as that of the first rolling mechanism 5.

  FIG. 7 shows a side view (FIG. 7A) and a front view (FIG. 7B) of the second rolling member. The second rolling members 67 a to 67 c are rod-shaped and the upper surface is formed in a plane. A plurality of protrusions 68 are formed in the lower part. The lower surface of each protrusion 68 is formed in the curved surface shape of the semicircular column in the axial direction along the direction in which the second rolling surface P2 is substantially orthogonal to the longitudinal direction. The curvature of the curved surface of the second pressure contact surface P2 is set to be the same as that of the first pressure contact surface P1.

  And as shown in FIG. 3, the 1st rolling mechanism 5 and the 2nd rolling mechanism 6 are combined and arrange | positioned so that the 2nd rolling members 67a-67c may be arrange | positioned between the 1st rolling members 57a-57c, respectively. Has been.

  In the example described above, the first rolling surface P1 of the first rolling member 57 and the second rolling surface P2 of each protrusion 68 of the second rolling member 67 are formed in a semi-cylindrical curved surface, as shown in FIG. As described above, the curvature of the rolled surface may be reduced, or the rolled surface may be a combination of the flat surface H and the curved surface R, and is not particularly limited. What is necessary is just to change suitably about the shape of a rolling surface according to characteristics, such as hardness of dough.

  For example, when the dough is soft and matured, it is easy to stretch, so it is better to roll on a rolling surface with a large curvature such as a semi-cylindrical curved surface. In addition, when the dough is not matured and the dough is hard, it is possible to reduce the curvature of the rolled surface as shown in FIG. 8 (a) or to the central area of the rolled surface as shown in FIG. 8 (b). What formed the plane H is good to use. In addition, when the dough is hard with little moisture, or when it is hardened by cooling, it is preferable to use a material in which the width of the plane H as shown in FIG.

  Next, operations of the first rolling mechanism 5 and the second rolling mechanism 6 will be described. When the motor 40 of the drive mechanism 4 is rotationally driven, as described above, the rotary disc 43 and the rotary disc 44 rotate in synchronization with each other, and the crankshaft bodies 53 and 63 move up and down. Therefore, as shown in FIG. 3, the first rolling mechanism 5 is lowered and the second rolling mechanism 6 is raised from the state where the first rolling mechanism 5 is raised and the second rolling mechanism 6 is lowered. The second rolling member 67 is in a state of being parallel (see FIG. 9), and the first rolling mechanism 5 is lowered and the second rolling mechanism 6 is raised (see FIG. 10). Behaves like you are.

  The heights of both rolling mechanisms are adjusted so that the distance between the rolling surfaces of the first rolling member and the second rolling member and the belt conveyor 3 when both rolling mechanisms are lowered is constant. What is necessary is just to adjust the height of both rolling mechanisms by providing the mechanism which adjusts the position of the drive mechanism 4 with respect to the base frame 2, for example.

  In this way, both rolling mechanisms move up and down and perform rolling operations alternately on the material f to be conveyed. FIG. 11 is an explanatory diagram regarding the rolling operation of both rolling mechanisms. In FIG. 11, the state which looked at the 1st rolling members 57a-57c and the 2nd rolling members 67a-67c from the upper direction is shown, and the arrow written in each rolling member is the 1st rolling surface P1 and the 2nd rolling surface. The rolling direction of the dough of P2 is shown.

  When the axial direction XX, which is the longitudinal direction of the pressing surface with respect to the dough of the first rolling member, is the action line, the action line XX is parallel to the transport direction D and passes through the center line YY passing through the center of the dough f. On the other hand, it is set in an oblique direction by an angle θ. And the action area | region S where the rolling operation | movement of a 1st rolling member and a 2nd rolling member is performed becomes a rectangular shape, The diagonal is set so that it may correspond with the centerline YY substantially.

  Since the 1st rolling surface P1 is formed in the semi-cylindrical curved surface of the axial direction along action line XX, material | dough will be rolled in the direction substantially orthogonal to action line XX. . Then, as shown by the arrows, the dough is rolled so as to be extruded toward both sides in the axial direction. On the other hand, since the 2nd rolling surface P2 formed in each projection part 68 is formed in the semi-cylindrical curved surface of the axial direction substantially orthogonal to the action line XX, the dough is rolled along the action line XX. To come. And as shown by the arrow, a dough is rolled so that it may extrude | push toward the both sides of the axial direction of each 2nd rolling surface P2.

  When the dough f is conveyed and enters the action area S at the position indicated by the dotted line, first, the first rolling member 57a located at the head of the diagonal line of the action area S presses the dough f and the first rolling surface P1 makes an arrow. Roll in direction. Next, the part rolled by the first rolling member 57a is pressed by the second rolling member 67a and rolled in the arrow direction by the second rolling surface P2. When the dough f is conveyed in this way, the first rolling surface P1 and the second rolling surface P2 are alternately rolled on each portion of the dough f, and are repeatedly rolled in two directions orthogonal to each other. Rolled almost uniformly in each direction. In this example, since the 1st rolling surface P1 and the 2nd rolling surface P2 are the same curved surface shape, since the same rolling effect | action is performed with respect to material | dough, it can roll more uniformly.

  In addition, by setting the action line in a diagonal direction by a predetermined angle, it is possible to suppress the influence of the dough f being conveyed when the first rolling member and the second rolling member are pressed. For example, if the angle θ is set to 45 degrees, the rolling directions of the first rolling surface P1 and the second rolling surface P2 are both shifted by 45 degrees with respect to the conveyance direction of the dough f, and the influence of the conveyance is the same. As a result, rolling in each direction is performed uniformly. actually,

  As described above, by setting the action line in a direction oblique to the conveyance direction by a predetermined angle, the dough f is rolled from the corner at the tip of the diagonal line, and the width gradually increases as the dough f is conveyed. Thus, the circular dough f can be rolled almost uniformly without breaking the shape, and the dough F can be rolled into a circular thin plate.

  FIG. 12 is an explanatory diagram showing an adjustment method when adjusting the positions of the first rolling member and the second rolling member. By moving the action area S so that the center line TT of the action area S defined by both rolling members rotates clockwise or counterclockwise, the rolling direction of both rolling members is rotated and adjusted. Therefore, it can be set to perform an optimum rolling operation. The movement of the action area S can be realized, for example, by rotating the first rolling mechanism 5 and the second rolling mechanism 6 together with the drive mechanism 4. In particular, even when the rolling direction of each of the first rolling surface P1 and the second rolling surface P2 is not uniform due to a mechanical error, the position is adjusted to adjust the angle θ of the action line XX and the optimum rolling direction. Can be set.

  Using the dough rolling apparatus described above, a dough that has been divided and formed into a truncated shape having a diameter of about 130 mm and a height of about 50 mm is rolled into a substantially circular and thin plate-like dough having a diameter of about 230 mm and a thickness of about 3 mm. We were able to. Moreover, it was possible to adjust the thickness after rolling to 3 mm to 7 mm by adjusting the space | interval between a rolling member and a belt conveyor.

  Moreover, in the example mentioned above, the 1st rolling surface P1 is formed in the whole surface of a 1st rolling member, and the 2nd rolling surface P2 is made into 2nd as a combination of the 1st rolling surface P1 and the 2nd rolling surface P2 in the action area | region S. Although it forms on each protrusion part of a rolling member, various combinations are possible for the combination of such 1st rolling surface P1 and 2nd rolling surface P2, and it chooses variously according to the characteristic of the material to be rolled. Can do.

  For example, in FIG. 13, two types of rolling members PA and PB are used as the rolling members (see FIG. 13A). In the rolling member PA, the first rolling surface P1 is formed for each projection, and in the rolling member PB, the second rolling surface P2 is formed for each projection. The lengths in the longitudinal direction of the protrusions of both rolled members are set to be the same.

  Then, the rolling members PA and PB are alternately arranged (see FIG. 13 (b)), and the action line is set in a diagonal direction with respect to the transport direction D as shown in FIG. 13 (c). Thus, uniform rolling operation can be performed by arranging the 1st rolling surface P1 and the 2nd rolling surface P2 alternately as the same shape.

  FIG. 14 shows a modification of FIG. 13, and a rolled member PA ′ in which one corner R of the rolled member PA is formed round is added (see FIG. 14A). The rolling members PA ′ are arranged on the most upstream side with respect to the conveying direction D (see FIG. 14B), and as shown in FIG. To be placed. The round corner portion R presses the dough first, so that the rolling operation can be performed so as not to damage the dough compared to the rounded corner portion.

  FIG. 15 shows a modified example of FIG. 13, using the rolling members PA and PB as in the case of FIG. 13 (see FIG. 15A), and alternately arranging the rolling members PA and PB. They are shifted in the longitudinal direction one by one (see FIG. 15B). And the inclination of the action line of rolling member PA and PB is made small with respect to the conveyance direction D (refer FIG.15 (c)). Therefore, it is useful when rolling a dough so that it may become long in the conveyance direction. In addition to this, as shown in FIG. 16, only two of the rolled members can be arranged shifted in the longitudinal direction as shown in FIG. 16, and the rolling members can be arranged in accordance with the shape of the material to be rolled. May be set as appropriate.

  FIG. 17 shows an example in which a rolling member PC having another shape is used. The rolling member PC has a plurality of protrusions formed in the same manner as the rolling members PA and PB, but the first rolling surface P1 and the second rolling surface P2 are alternately formed on each protrusion. FIG. 18 shows a front view (FIG. 18A), a FF sectional view (FIG. 18B), and a GG sectional view (FIG. 18C) of the rolling member PC. The 1st rolling surface P1 and the 2nd rolling surface P2 are formed in the same semi-cylindrical curved surface, the axial direction of the 1st rolling surface P1 is set to the longitudinal direction of the rolling member PC, and 2nd rolling The axial direction of the surface P2 is set to a direction orthogonal to the longitudinal direction.

  Then, as shown in FIG. 17B, if the rolling members PC are arranged so as to form a rectangular action region, as shown in FIG. 17C, the first rolling surface P1 and the second rolling surface P2 is arranged alternately throughout the working area. Therefore, compared with the case of FIG.13 and FIG.14, although the 1st rolling surface P1 and the 2nd rolling surface P2 are respectively arranged in 1 row, the arrangement direction is a direction orthogonal to an action line. In this example, a rolling member PC 'in which one corner R of the rolling member PC is formed round is added.

  19 and 20 show another example using the rolling member PC. In the example of FIG. 19, as shown in FIG. 19A, every other rolling member PC is arranged with its longitudinal direction reversed. Therefore, as shown in FIG. 19B, the first rolling surface P1 and the second rolling surface P2 are set so as to be alternately arranged in a direction orthogonal to the longitudinal direction of the rolling member PC. Further, as in the example of FIG. 20, only some of the rolling members PC may be arranged in the same direction, and various arrangements of the rolling members PC may be considered other than this.

  The rolling members described above are appropriately combined, and the arrangement and size of the first rolling surface P1 and the second rolling surface P2 can be finely set in accordance with the characteristics of the material to be rolled.

  In addition, although the columnar curved surface was illustrated and demonstrated about the 1st rolling surface P1 and the 2nd rolling surface P2, shapes other than columnar curved surfaces, such as a hemispherical curved surface, may be used. Moreover, what is necessary is just to set suitably the shape and magnitude | size of the projection part formed in a rolling member, and the space | interval between projection parts as needed based on the shape of a rolling surface, the rolling characteristic of a dough, etc.

  In addition to the pizza dough and bread dough described above, the dough rolling apparatus according to the present invention can roll dough made of various materials such as dough using wheat flour (weak flour or strong flour) or dough obtained by mixing rice flour with flour. It can be applied to a wide range of uses.
