Description

  The present invention relates to a dough sheet forming apparatus for forming an inner material such as cream, jam, rice cake or minced meat by folding it with a thin dough sheet.

  2. Description of the Related Art Conventionally, foods formed by wrapping the above-described inner material such as cream with a thin dough sheet have been developed, and the present inventors are proceeding with development of such food forming apparatuses. For example, in Patent Document 1, a pallet conveyor in which a large number of pallets with lever operation openings are arranged is installed, a flexible mat is fixed to each pallet so as to cover the lever operation openings of the pallets, and the tongue lever is attached to the lever. A forming apparatus is described in which a thin dough sheet protruding from an operating port and on which an inner material is placed is bent together with a flexible mat, and a food that encloses the inner material with the dough sheet F by using such a forming apparatus is described. Is described as being able to be molded. In FIGS. 10 to 13, when the corners of the rectangular dough sheet are folded so as to overlap each other above the inner material, the four corners of the dough sheet are gathered to the center. When bending and forming so that the opposite corners overlap each other, when forming the four corners of the fabric sheet in close contact with the upper surface of the inner material so as to be folded toward the center, In this case, the two sides are formed so as to overlap each other.

Further, in Patent Document 2, in the molding apparatus described in Patent Document 1, members such as a balance lever, a press rod, a stop lever, and a press lever are used so that the inner material wrapped with the fabric sheet does not move when the fabric sheet is bent. The point which tried to press down the cloth sheet | seat and inner material which were bent in this is described. Patent Document 2 describes a specific example in which a rectangular dough sheet is formed into four folds. However, as shown in FIG. 33, the dough is formed into three folds so that two opposing sides overlap each other. It is described that it can be formed in two so that two sides overlap.

  In the above-described forming apparatus so far, four lever operating ports formed on the pallet are provided along the diagonal line of the dough sheet, and therefore suitable for quadruple folding where the corner of the dough sheet is bent toward the center. However, since the folding position by the tong lever is fixed, it is necessary to change the arrangement of the flexible mat and the fabric sheet according to it, from the viewpoint of practical use. However, there is a drawback that it can be used only for four-fold.

  Then, this invention aims at providing the shaping | molding apparatus which can shape | mold a dough sheet by various folding methods, without changing the position of the forming sheet and dough sheet arrange | positioned on a pallet. .

  The dough sheet forming apparatus according to the present invention includes a plurality of pallets arranged in the transport direction of the transport conveyor and formed with a plurality of long holes, and a molding made of a flexible material and placed on the upper surface of the pallet. A mat, and a lever driving means that is disposed below the pallet and moves up and down so that the tongue lever is inserted and protruded into the elongated hole, and the tongue lever protrudes from the elongated hole and is molded. In a dough sheet forming apparatus for forming a dough sheet placed on the forming mat by bending the mat so as to be folded, the dough sheet forming apparatus includes width setting means for setting a bending width of the forming mat by the tongue lever. It is characterized by. Further, the forming mat is partially fixed on the pallet so that a rectangular dough sheet disposed on the upper surface thereof is set to a bending width that can be bent along a diagonal line, and the width setting means Is characterized in that the bending width is set small by partially pressing the molding mat against the pallet so that the corner of the rectangular fabric sheet can be bent toward the center. Furthermore, the molding mat is partially fixed on the pallet at a position corresponding to one of the two regions defined by the diagonal line in the central portion of the rectangular dough sheet disposed on the upper surface thereof. It is characterized by that. Further, the pallet has four elongated holes formed along diagonal lines from the center of the rectangular dough sheet disposed on the forming mat to the four corners, and further, the center of the dough sheet Two elongated holes are formed along a perpendicular line extending from two to two opposite sides.

  Since the present invention has a configuration as described above and is provided with a width setting means for setting a bending width by the tongue lever of the forming mat, the bending width of the forming mat is changed according to how the dough sheet is folded. Therefore, another folding method can be performed without changing the arrangement of the forming mat and the dough sheet.

  Specifically, if the forming mat is partially fixed on the pallet so that the rectangular dough sheet placed on the upper surface of the forming mat is set to a bending width that can be bent along a diagonal line, As shown in FIG. 33 (a), the dough sheet can be formed into a triangular fold that is folded along a diagonal line, and as a width setting means, the corner of the rectangular dough sheet can be bent toward the center. Further, by using means for partially pressing the molding mat against the pallet and setting the bending width to be small, it is possible to form the conventional four-fold (see FIG. 33B). And when fixing a shaping | molding mat on a pallet, it is partially in the position corresponding to one area | region of the two area | regions demarcated by the diagonal line in the center part of the rectangular-shaped dough sheet arrange | positioned on the upper surface of a shaping | molding mat. If it fixes to, the bending | flexion operation | movement which bends a cloth sheet | seat along a diagonal can be performed stably.

  Further, as a plurality of long holes formed in the pallet, four long holes are formed along diagonal lines from the center of the rectangular dough sheet arranged on the forming mat to the four corners, and the center of the dough sheet is formed. If two long holes are formed along the perpendicular to the two opposite sides, the tong lever protrudes from the long hole formed along the diagonal line of the fabric sheet, and can be molded by triangular and quadruple folds. When the tongue lever protrudes from the long hole formed along the vertical line, as shown in FIG. 33 (c), the operation is performed by folding in three so that the two opposite sides are folded on the upper surface of the inner material. Can be performed.

  And, since these molding operations can be performed without changing the arrangement of the molding mat and the dough sheet, a molding apparatus that can handle various molding operations that could only be molded with a dedicated machine until now is put to practical use. Can be

  Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is an overall configuration diagram relating to the dough sheet forming apparatus 1. In the molding apparatus 1, an endless transfer conveyor 3 is stretched by a transfer roller 4 in a machine frame base 2, and the transfer roller 4 is driven to rotate by a drive motor 5. It is designed to be conveyed. A large number of rectangular pallets 6 in a plan view are arranged and fixed on the conveyor 3 along the conveying direction.

  FIG. 2 is a plan view (FIG. 2A) and a TT cross-sectional view (FIG. 2B) relating to a single pallet 6 portion. Is fixed. 3 is an exploded perspective view showing a mounting state of the molding mat 7 to the pallet 6. FIG. 4 is a plan view of the pallet 6. FIG. 5 is a plan view of the molding mat 7. FIG. a)), side view (FIG. 5B), and bottom view (FIG. 5C).

  The pallet 6 is formed of a thick metal or resin plate-like body, and includes a mounting portion 6a and a mounting portion 6b having approximately the same size as the molding mat 7, and the mounting portion 6a has a diagonal line S1 of the molding mat 7. And four long holes 60 to 63 are formed along S2. Further, two long holes 64 and 65 are formed along a perpendicular line T extending toward two opposite sides from the center of the molding mat 7 (intersection of the diagonal lines S1 and S2). These six long holes 60 to 65 are formed to have a predetermined width and penetrate the pallet 6. An attachment hole 66a for inserting the screw rod 74a of the molding mat 7 and a nut relief hole 66b for inserting the nut 76b are formed through the central portion surrounded by the long holes. A screw hole 67 for attaching to the conveyor 3 is formed in the attaching portion 6b. After the pallet 6 is arranged at a predetermined position of the conveyor 3, the screw is inserted into the screw hole and fixed.

  The molding mat 7 includes a thin plate-like mat body 70 made of a flexible resin material, and can be easily bent so as to be bent toward the upper surface, and can be quickly restored from the bent state to the original state. It has a restoration characteristic to do. On the bottom surface of the mat body 70, four guide portions 71 are provided from the four corner portions toward the center along the diagonal lines S1 and S2, and each guide portion 71 is formed by a pair of linear protrusions. ing. A pair of metal mounting plates 73a and 73b arranged opposite to both sides of the diagonal line S1 are disposed in the center portion surrounded by the guide portion 71.

  A pair of long screw rods 74a project from the bottom surface of the mounting plate 73a, and are inserted into holes formed in the mat body 70 so as to project toward the bottom surface side of the mat body. The fixing plate 75a is fitted into the protruding pair of screw rods 74a and is pressed against the bottom surface of the mat body 70. The screw rod 74a is inserted into the mounting hole 66a of the pallet 6 and is fastened and fixed by the nut 76a. Thus, the mounting plate 73a and the fixing plate 75a are pressed and fixed to the upper surface side and the lower surface side of the mat body 70, respectively.

  The mounting plate 73a is formed in a trapezoidal shape in which a part of a rectangle is cut, two sides corresponding to the upper base and the lower base are set along the diagonal line S1, and the side corresponding to the height is the diagonal line S2. It is set along. The remaining sides are set so as to be orthogonal to the perpendicular line T. The fixed plate 75a is formed in a rectangular shape having substantially the same width and the same length as the mounting plate 73a.

  Therefore, the mounting plate 73a and the fixing plate 75a are disposed in one region defined by the diagonal line S1 at the center of the mat body 70, and the mat body 70 is sandwiched and fixed between the plates. . Therefore, when the screw rod 74a is inserted into the mounting hole 66 of the pallet 6 and fastened and fixed by the nut 76a, the forming mat 7 is bent with respect to each side of the mounting plate 73a. For example, when the molding mat 7 is bent so as to lift up the corners, the bending operation is performed from the upper to the lower and bottom sides of the mounting plate 73a to the corners corresponding to the height. When the side of the forming mat 7 facing the side perpendicular to the perpendicular line T is bent so as to be lifted, a bending operation is performed between the side of the mounting plate 73a and the side of the forming mat 7. To be done.

  The mounting plate 73b is provided with a pair of short screw rods 74b. A fixing plate 75b is fixed to the screw rod 74b protruding to the bottom surface side of the mat body 70 by a nut 76b. The mounting plate 73b and the fixing plate 75b are disposed in the other region defined by the diagonal line S1 at the center of the mat body 70, and the mat body 70 is sandwiched and fixed between the plates. . The mounting plate 73b and the fixed plate 75b are formed in the same shape as the mounting plate 73a and the fixed plate 75a. When the forming mat 7 is fixed to the pallet 6 with the screw rod 74a, the nut 76b is received in the nut relief hole 66b of the pallet 6.

  In the mounting plate 73b, the nut 76b moves up and down through the nut relief hole 66b when the forming mat 7 is bent at the fold line along the diagonal line S1, but the forming mat 7 is moved along the diagonal line S1. When folded so as to overlap with the fold, it is possible to realize a bent state in which the mounting plate 73b is bent round without being bent deeply along the diagonal line S1. .

  As will be described later, since the dough sheet is cut into a square shape having substantially the same size as the forming mat 7 and disposed on the forming mat 7, the diagonal lines S1 and S2 described above coincide with the diagonal line of the dough sheet, Similarly, the perpendicular line T matches the perpendicular line from the center of the dough sheet toward two opposite sides. Even if the size of the dough sheet is cut into a square shape smaller than that of the molding mat 7, it is the same as long as the dough sheet is arranged so as to substantially match the center of the molding mat 7.

  As shown in FIG. 1, the conveyor 3 is set so as to convey the pallet 6 in a substantially horizontal state in the upper part of the machine base 2, and intermittently conveys the pallet 6 by the length in the conveying direction. To be controlled.

  On the upstream side in the conveyance direction of the row of pallets 6 arranged in the conveyance direction, a conveyance belt 8 that conveys the thinly stretched dough sheet F, and the dough sheet F that is conveyed in a belt shape corresponding to the width of the pallet 6. A circular cutter 9 to be cut is disposed, and both sides of the dough sheet F are cut and formed into a belt shape by rotating the circular cutter 9 while the dough sheet F is conveyed by the conveying belt 8. The cut strip-shaped dough sheet F is conveyed and placed on the forming mat 7 attached to the upper surface of the pallet 6 in synchronization with the conveyance of the pallet row.

  The dough sheet F placed on the pallet row is transported together with the pallet 6, and the dough is formed by pressing a hole forming member 10 provided with a plurality of projections for forming a gas venting hole by a driving means (not shown). After forming a plurality of holes on the surface of the sheet F, the cutter 11 is moved up and down by a driving means (not shown) to cut the dough sheet F by the length of the forming mat 7 in the conveying direction. The cut dough sheet F is formed in substantially the same square shape as the forming mat 7 and is conveyed while being placed on each forming mat 7.

  Above the rectangular dough sheet F transported by each pallet 6, a water coating brush 12 that gives moisture to the upper surface of the dough sheet F, a hopper 13 filled with the inside material, and an inside material supplied from the hopper 13 are shown. A nozzle 14 for discharging and a divider 15 for dividing the discharged inner material by a predetermined amount are provided. For example, the divider 15 is moved so as to traverse the rod-shaped inner material discharged using a thin wire rod, and cuts and divides it by a predetermined amount. The divided inner material is disposed at a predetermined position on the upper surface of the dough sheet F to be conveyed.

  A plurality of tong lever driving mechanisms 20 are arranged below the row of pallets 6, and various pressing mechanisms 30 are arranged on the upper side so as to face the tong lever driving mechanism 20 in accordance with the folding method.

  FIG. 6 shows a schematic configuration diagram of the tong lever driving mechanism 20. In this example, when there are two pallet rows in the transport direction, the tongue levers are protruded from the same pallet in each row. It is set to operate. FIG. 6A is a configuration diagram illustrating an operating state in which the tongue levers 200a and 200b are raised, and FIG. 6B is a configuration diagram illustrating a standby state in which the tongue levers 200a and 200b are lowered.

  The tongue lever drive mechanism 20 includes a cam 22 fixed to a drive shaft 21 to which a drive force is transmitted from the drive motor 5, and a cam groove 22 a formed in the cam 22 is rotatable with respect to the drive lever 24. The attached cam roller 23 is inserted. The drive lever 24 is pivotally supported at one end portion 24a so that the cam roller 23 moves up and down following the cam groove 22a by the rotation of the cam 22, so that the drive lever 24 rotates in the vertical direction. One end of a connecting member 25a is rotatably attached to the other end of the drive lever 24, and one end of an L-shaped connecting member 25b is rotatably attached to the other end of the connecting member 25a. ing. The connecting member 25b is pivotally supported by the frame 27 at the bent portion, and reciprocally swings in the left-right direction in conjunction with the vertical turning operation of the drive lever 24. One end portion of the connecting member 25c is rotatably attached to the other end portion of the connecting member 25b, and operating levers 26a and 26b are arranged in the vertical direction on the other end portion of the connecting member 25c. . And the lower end part of the operation lever 26a arrange | positioned at the upper part and the upper end part of the operation lever 26b arrange | positioned at the lower part are rotatably attached to the other end part of the connection member 25c coaxially. The upper end portion of the operating lever 26 a is rotatably attached to the bottom surface of the operating table 201, and the lower end portion of the operating lever 26 b is rotatably attached to the frame 27. Accordingly, when the connecting member 25b reciprocally swings in the left-right direction in conjunction with the turning operation of the drive lever 24, the connecting member 25c moves forward and backward in the left-right direction, and in conjunction with the forward-backward movement of the connecting member 25c. The operation levers 26a and 26b operate from a state in which the operation levers 26a and 26b extend in the up-down direction to a bent state. Therefore, the operating table 201 moves up and down.

  The operation table 201 is supported by a pair of left and right support portions 202a and 202b. In FIG. 6, a portion of the support portion 202a is shown in a partial cross-sectional view. The support 202a includes a cylindrical actuating member 203a inserted in a hole formed in the actuating table 201 and an actuating rod 204a slidably inserted into the actuating member 203a.

  A flange portion 205 a is formed on the outer periphery of the upper portion of the operating member 203 a, and the lower surface of the flange portion 205 a is in contact with the upper surface of the operating table 201. The lower part of the actuating member 203 a is accommodated in a support cylinder part 27 a erected on the frame 27. The upper end of the actuating rod 204a is fixed to the lower surface of the support base 206, and a mounting hole is formed in the lower portion thereof in the axial direction, and the coil spring is erected on the mounting portion 27b of the frame 27 in the mounting hole. 28 is accommodated. Further, a ring-shaped stopper 207a is attached to the lower end portion of the actuating rod 204a, and when the actuating rod 204a rises, the stopper 207a comes into contact with the lower end of the support cylinder portion 27a so as to limit further elevation. It has become. A coil spring 29 is disposed between the upper surface of the flange portion 205a of the operating member 203a and the lower surface of the support base 206a so as to surround the operating rod 204a. The coil spring 28 constantly urges the operating rod 204a upward, and the coil spring 29 urges the flange portion 205a and the support base 206 to be separated from each other, and the urging force of the coil spring 29 is applied to the coil spring 28. It is set to be larger than the power.

  Although the support portion 202a has been described above, the support portion 202b has the same configuration. The operation table 201 and the support table 206 are supported by the support portions 202a and 202b.

  As the operating mechanism of the tongue levers 200a and 200b, the lifting rods 208a and 208b attached through the operating base 201 and the support base 206, and the support bars 209a and 210a protruding in the left-right direction at the tip ends of the lifting rods 208a and 208b. In addition, actuating links 212a and 212b having lower ends rotatably attached to the front ends of 209b and 210b and support bars 209a and 209b are disposed. The upper ends of the operation links 212a and 212b are rotatably attached to one end portions of the operation bars 213a and 213b, respectively, and the other end portions of the operation bars 213a and 213b are supported on the upper surface of the support base 206. The projections 206a and 206b are pivotally attached to the tops. The tongue levers 200a and 200b are erected with their lower ends fixed to the one ends of the operating bars 213a and 213b, respectively. Balance levers 211a and 211b are erected at the front ends of the support bars 210a and 210b.

  The lower parts of the lifting rods 208a and 208b are fixed so as to pass through the operation base 201, and the upper part thereof is slidably attached through the support base 206. Therefore, when the operating table 201 moves up and down, the lifting rods 208a and 208b move up and down. Further, the support table 206 is applied with a biasing force to the operation table 201 by the coil spring 29 and is brought into pressure contact with the support bars 209 a and 210 a and 209 b and 210 b, and moves up and down together with the operation table 201. However, when the support base 206 is raised to a predetermined height, the rise is restricted by the stopper 207a at the lower end of the operating rod 204a fixed to the lower surface of the support base 206. When the operating base 201 further rises in a state where the raising of the support base 206 is restricted, the lifting rods 208a and 208b rise while the coil spring 29 is compressed. For this reason, the support bars 209a and 210a and 209b and 210b are raised, and the end portions of the operation bars 213a and 213b and the balance levers 211a and 211b are raised. At this time, the other end portions of the operation bars 213a and 213b are attached to the support protrusions 206a and 206b of the support base 206, which is restricted from rising, so that the one end side is rotated upward as it rises. Thus, the tongue levers 200a and 200b perform a rotating operation.

  FIG. 7 is an explanatory view showing a series of operation processes of the tongue lever 200a. At the stage where the operating table 201 is lowered, the tongue lever 200a is also lowered to enter a standby state (FIG. 7 (a)). In the standby state, the operating base 201 and the support base 206 are energized by the coil spring 29 so that the interval is widened, the lifting rod 208a is also lowered, and the tongue lever 200a is tilted.

  When the operating base 201 is raised, the whole operating base 201 and the support base 206 are lifted with the coil spring 29 being urged, and the tongue lever 200a is also lifted in an inclined state so that the operating claw at the tip thereof is upward. Protruding. Similarly, the balance lever 211a is also raised. FIG. 7B shows a case where the support platform 206 is raised until the rise is restricted.

  When the operating base 201 is further raised in a state where the support base 206 is restricted to be lifted, only the operating base 201 is lifted while compressing the coil spring 29, and the lifting rod 208a is lifted so as to come out of the support base 206. Therefore, it will be in the operation state which rotates from the state in which the operation claw of the tongue lever 200a inclined (FIG.7 (c)). At that time, the balance lever 211a further moves up.

  When the actuating table 201 rises to the highest position and starts to descend, only the actuating table 201 is lowered so that the compressed state of the coil spring 29 is released, so that the lifting rod 208a is lowered with respect to the support table 206. Then, the tongue lever 200a is tilted again (FIG. 7D). When the elevating rod 208a is lowered and the support bars 209a and 210a are brought into contact with the support base 206, the operating base 201 and the support base 206 are further lowered integrally by the biasing force of the coil spring 29, and the tongue lever 200a is lowered. Thus, the standby state is set (FIG. 7E).

  The presser mechanism 30 may be provided with various mechanisms depending on how the dough sheet F is folded. For example, FIG. 8 is a configuration diagram relating to the arrangement of the presser mechanisms in the case of quadruple folding shown in FIG. In this case, in order to fold the four corners of the dough sheet toward the center, four tong lever driving mechanisms 20A to 20D are arranged in the transport direction.

  As the presser mechanism, the upper fabric presser mechanism 300 that presses the folded fabric sheet placed on the upper surface of the inner material, the lower fabric presser mechanism 310 that presses the folded fabric fold, and the molding mat 7 are pressed to form. A mat presser mechanism 320 for setting the bending width of the mat is arranged.

  The upper fabric presser mechanism 300 fixes presser members 301 and 302 each having a disc-like presser plate to both ends of a support bar 304 fixed to the lower end portion of the drive rod 303, and drives the air cylinder 305 to press the presser member 301 and 302 is moved up and down. The holding members 301 and 302 are moved down to press the upper surface of the inner material with a disk-shaped pressing surface, thereby preventing the dough sheet placed on the upper surface from being detached from the inner material. .

  The lower material presser mechanism 310 has a support member 313 that supports the bar-like presser members 311 and 312 substantially horizontally attached to a drive rod of the air cylinder 314, and drives the air cylinder 314 to move the presser members 311 and 312 up and down. The presser members 311 and 312 act so as to press-contact the fold portion of the fabric sheet folded downward and linearly, so that the subsequent fabric folding can be finished finely.

  The mat presser mechanism 320 has a support member 323 that supports rod-like presser members 321 and 322 so as to be substantially vertical, and is attached to a drive rod of the air cylinder 324, and the air cylinder 324 is driven to move the presser members 321 and 322 up and down. Move. The holding members 321 and 322 descend and press the forming mat against the pallet at a predetermined position corresponding to the bending width of the forming mat to set the bending width.

  Also in the case of bi-folding, which will be described later, since the bending operation is performed so that one corner of the forming mat is bent along the diagonal line, it is necessary to set the bending width in the case of bi-folding and the bending width in the case of quadruple folding. However, by providing the mat presser mechanism 320 as a width setting means for setting the bending width, both molding operations can be easily performed with a single molding apparatus.

  FIG. 9 is a configuration diagram relating to the arrangement of the presser mechanism in the case of tri-folding (contract folding) shown in FIG. In this case, two tong lever drive mechanisms 20E and 20F are arranged in the transport direction in order to fold two opposing sides of the dough sheet toward the center.

  As the presser mechanism, an upper fabric presser mechanism 330 that presses the fabric sheet that is folded and placed on the upper surface of the inner material, and a lower fabric presser mechanism 340 that presses the folded folds of the folded fabric are arranged.

  The upper fabric pressing mechanism 330 attaches a support member 332 that supports a pressing member 331 having a rectangular pressing plate to a drive rod of the air cylinder 333, and drives the air cylinder 333 to move the pressing member 331 up and down. The pressing member 331 descends and acts to press-contact the upper surface of the inner material with a rectangular pressing surface, thereby preventing the dough sheet placed on the upper surface from being detached from the inner material.

  The lower material presser mechanism 340 attaches a support member 343 that supports the bar-like presser members 341 and 342 substantially horizontally to the drive rod of the air cylinder 344, and drives the air cylinder 344 to move the presser members 341 and 342 up and down. The holding members 341 and 342 can be finished so as to wrap the entire inner material in a state of being in close contact with the dough sheet by acting so that both ends of the dough sheet folded down and linearly press-contact with each other. .

  FIG. 10 is a configuration diagram relating to the arrangement of the presser mechanism in the case of the double fold (triangular fold) shown in FIG. In this case, one tong lever drive mechanism 20G is arranged to fold the dough sheet along the diagonal line. The tongue lever drive mechanism 20G has a long balance lever, and when the tongue lever is raised and protrudes from the long hole of the pallet, the balance lever protrudes simultaneously from the opposed long hole.

  The presser mechanism includes a lower fabric presser mechanism 350 that presses the three corners of the fabric sheet against the forming mat, a swing arm mechanism 360 that tilts the folded fabric sheet in a predetermined direction, and an inner material covered with the fabric sheet. An upper fabric presser mechanism 370 that presses the upper surface of the fabric sheet and a lower fabric presser mechanism 380 that presses two adjacent sides of the fabric sheet are arranged.

  The lower fabric presser mechanism 350 is provided with a support member 354 that supports and supports the presser members 351 to 353 at positions facing the three corners of the fabric sheet, and drives the air cylinder 355. The pressing members 351 to 353 are moved up and down. The holding members 351 to 353 are lowered so that the three corners of the dough sheet are brought into pressure contact with the forming mat by the rectangular pressing surface so that the corners of the dough are folded during the folding operation by the tongue lever. Prevent inadvertent movement.

  The swing arm mechanism 360 attaches an arm member 361 attached downward to a drive rod of the air cylinder 362, and drives the air cylinder 362 to swing the arm member 361 left and right. The arm member 361 acts to bend the dough sheet in a predetermined direction by further bending the forming mat bent by the tong lever by swinging left and right.

  The upper fabric presser mechanism 370 attaches a support member 372 that supports a presser member 371 having a rectangular press plate to the drive rod of the air cylinder 373 and drives the air cylinder 373 to move the presser member 371 up and down.
