  Hereinafter, a system configuration for manufacturing a food product (product) having a configuration in which an inner packaging material (inner material) is wrapped with a skin material made of food dough such as bread dough will be schematically shown in FIG. As shown conceptually, they are lined up.

  A food dough supply apparatus 1 is provided on the upstream side of the food production line. The food dough supply device 1 forms food dough such as bread dough into a continuous food dough, measures the continuous food dough, cuts it into a predetermined weight of food dough piece P1, and supplies it to the downstream side. It is what makes. This type of food dough supply apparatus 1 is, for example, as described in Japanese Patent Application Laid-Open No. 2001-78651 and has a known configuration, and thus detailed description of the food dough supply apparatus 1 is omitted. To do. In addition, the case where the food dough piece P1 is supplied in two rows from the food dough supply apparatus 1 is illustrated. In this case, the food dough is divided into two by a disc-shaped cutter. However, the supply of the food dough piece P1 may be one row or a plurality of rows of two or more rows.

  Arrangement conveyor 3 is arranged on the downstream side of food dough supply device 1, and dough spheroidizing device 5 for spheroidizing food dough piece P <b> 1 is arranged on the downstream side of arrangement conveyor 3. . The arrange conveyor 3 serves to align the positions and rows of the plurality of rows of the food dough pieces P1 supplied from the food dough supply device 1.

  That is, the arrangement conveyor 3 is configured to be capable of individually driving a plurality of belt conveyors 3A and 3B with respect to the number of rows of food dough pieces P1 supplied from the food dough supply apparatus 1. As a configuration for aligning the positions of the food dough pieces P1, when the food dough pieces P1 on the belt conveyors 3A and 3B are individually detected by sensors (not shown) arranged at predetermined positions, the belt conveyors 3A and 3B are detected. The food dough piece P1 can be aligned at a predetermined position by individually stopping. Note that the column is aligned upstream.

  As described above, after the food dough pieces P1 on the belt conveyors 3A and 3B are aligned at a predetermined position, the respective belt conveyors 3A and 3B are synchronously rotated and transported (transferred), whereby a plurality of food dough pieces are obtained. The P1 can be supplied (carried in) to the dough spheroidizing device 5 in a state where the P1s are aligned (a state in which the positions in the transport direction are substantially coincident).

  As shown in FIGS. 2 and 3, the dough spheroidizing device 5 is for spheronizing the rectangular food dough piece P1 supplied from the food dough supplying device 1, and is arranged as described above. 3 is provided with a conveyor belt conveyor 7 for receiving the food dough piece P1 from 3 and transporting (transferring) it to the downstream side. The conveyor belt conveyor 7 has a wide configuration so as to correspond to the belt conveyors 3A and 3B, and is made of an appropriate material such as rubber or resin. While maintaining a relatively large friction with the piece P1, fine irregularities are formed to prevent adhesion. The unevenness is formed, for example, by intersecting a large number of thin grooves or protrusions. That is, by providing fine irregularities on the surface of the conveyor belt conveyor 7, the contact area between the food dough piece P1 and the conveyor belt conveyor 7 can be halved, and adhesion can be effectively prevented.

  A movable plate 9 extending so as to straddle the conveyor belt conveyor 7 is disposed near the center of the conveyor belt conveyor 7 in the conveyance direction (arrow A direction) and above the conveyor belt conveyor 7. Both end portions of the movable plate 9 are rotatably supported by an eccentric shaft 13 attached to an upper end portion of a rotating shaft 11 that is provided on both sides of the conveyor belt conveyor 7 so as to be rotatable. One rotary shaft 11 is appropriately interlocked with a motor M1 such as a servo motor.

  A vertically moving actuator 15 such as an air cylinder is attached to a substantially central portion of the movable plate 9 in the longitudinal direction, and a vertically moving member 17 such as a piston rod provided on the vertically moving actuator 15 so as to freely move up and down. A support plate 19 is attached to the lower end of the plate. A plurality of molding cups 21 are provided on the lower surface of the support plate 19 corresponding to the rows of the food dough pieces P1 so as to cover the food dough pieces P1 on the conveyor belt conveyor 7 from above. .

  Each molding cup 21 is provided with a pressing pad 23 that can press the food dough piece P1 to be spheroidized from above, so that it can move up and down. The lower limit position of the pressing pad 23 is regulated by a nut screwed to the upper end portion of the vertical rod 23 </ b> R provided on the upper portion of the pressing pad 23 being in contact with the upper surface of the support plate 19 or the molding cup 21. Yes. The pad 23 is always pressed and urged downward by an elastic member such as a coil spring elastically mounted between the pad 23 and the ceiling of the support plate 19 or the molding cup 21.

  Further, the dough spheroidizing device 5 is provided with a motor M2 for driving the conveyor belt conveyor 7, and an origin position detection sensor 25 for detecting the origin position of the rotating shaft 11 is appropriately fixed. Provided in the department. Further, a control device 27 for controlling the operations of the motors M1, M2 and the vertical movement actuator 15 is provided, and the rotational speed and the rotation time of the motors M1, M2 are set and inputted, and the dough spheroidization is performed. An operation panel 29 including a drive and stop switch for the device 5 is provided.

  With the above-described configuration, the food dough piece P1 that is intermittently driven under the control of the control device 27 and is carried from the arrange conveyor 3 onto the conveyor belt conveyor 7 is positioned below each molding cup 21. When this happens, the operation of the conveyor belt conveyor 7 is stopped. Thereafter, the vertical movement actuator 15 is actuated to lower the support plate 19, and the food dough pieces P <b> 1 on the conveyor belt conveyor 7 are covered from above by the molding cups 21. When the motor M1 is driven to rotate the rotating shaft 11, the movable plate 9 rotates eccentrically while keeping the longitudinal direction constant.

  When the movable plate 9 is eccentrically rotated as described above, the molding cups 21 are also eccentrically rotated at the same time, and the contact position between the inner surface of each molding cup 21 and the food dough piece P1 is changed sequentially, and the food dough piece P1 is passed along the meridian direction. The food dough piece P1 is spheroidized (the food dough piece P1 is rounded) while applying a tensile stress to.

  That is, the food dough P1 is formed in a spherical shape while rotating (revolving) about a substantially vertical axis and rotating eccentrically (revolving) by being rotated by the eccentric rotation of the molding cup 21.

  At this time, since the upper part of the food dough piece P1 is pressed by the pad 23, the food dough piece P1 is not turned upside down, and is spheroidized by frictional contact between the conveyor belt conveyor 7 and the food dough piece P1. The surface of the food dough will be spheroidized while being pulled. That is, stress (tensile) in the meridian direction is applied to the spherical body surface. At this time, wrinkles are formed on the lower surface of the food dough piece P1, but spheroidization by applying stress in the meridian direction is effectively performed.

  When the rotation of the motor M1 is continued for a predetermined time and the food dough piece P1 is spheroidized, the driving of the motor M1 is stopped under the control of the control device 27, and the motor M1 is slightly reversely rotated. . At this time, the origin detection sensor 25 detects the origin position of the rotating shaft 11 (for example, the eccentric shaft or the origin position of the rotary encoder provided in the motor M1 or the dog provided on the rotating shaft 11). It is desirable to rotate M1 back to the original position.

  As described above, the molded cup 21 is eccentrically rotated to spheroidize the food dough piece P1 in the molded cup 21, and then the molded cup 21 is slightly rotated in the reverse direction to make the food spherical with the inner surface of the molded cup 21. The dough is slightly separated from the dough, and adhesion when the molding cup 21 is raised can be prevented. Moreover, by stopping the rotating shaft 11 at the origin position by reverse rotation, each molding cup 21 can always be stopped at a fixed position, and when the next food dough piece P1 is started to be spheroidized, Is something that can be started.

  As described above, the height method of the food dough P2 spheroidized by eccentrically rotating the molding cup 21 is substantially constant, and the wrinkle portion caused by the frictional contact with the conveyor belt conveyor 7 is the same as that of the food dough P2. It is located on the lower surface.

  The spheroidized food dough P2 as described above is then transferred to the flattening device 31 (see FIG. 4) and flattened into a disk shape. When flattening the food dough P2, when the food dough P2 is spheroidized, a disk in which the vicinity of the rotation center of the food dough P2 (around the vertical axis passing through the top of the food dough P2) is located at the center It is desirable to flatten the shape. By flattening the food dough P2 as described above, the direction of the tensile stress imparted to the food dough P2 is preferably the radial direction (radial direction) of the food dough P4 when flattened in a disk shape. is there.

  As described above, the spheroidized food dough P2 is flattened into a disk shape as described above, and the food dough P2 is flat on the conveyor belt conveyor 7 or on the conveyor downstream of the conveyor 7. Therefore, it is possible to adopt a configuration in which crushing is performed from above. However, it is desirable that the food dough adheres to the conveyor belt conveyor 7 and that the wrinkle portion of the lower surface of the food dough P2 is the upper surface (in order to improve the appearance of the product, the wrinkle portion is desirably the upper surface. However, it is not always necessary to be on the upper surface), and in consideration of productivity improvement, the food dough P2 is supplied between the rotating pair of pressing rollers and is flattened into a disk shape. Is desirable.

  Therefore, as shown in FIGS. 1 and 4, the flattening device 31 includes a pair of upper and lower pressing rollers 33 (upper side) that are rotated by a motor (not shown) to crush and flatten the food dough P2. (Only the pressing roller is shown) is rotatably provided. The interval between the pair of pressing rollers 33 is configured to be adjustable so that the thickness when flattened can be adjusted, and the food dough is placed between the pressing rollers 33 on the upstream side of the pressing roller 33. A supply conveyor 35 for supplying is disposed, and an unloading conveyor 37 for unloading the food dough flattened in a disk shape is disposed on the downstream side.

  By the way, when the spheroidized food dough is supplied between the pair of pressing rollers 33 and flattened, the food dough tends to be stretched in the supply direction with respect to the pressing roller 33, and the flattened food dough is formed in an oval shape. Tend to be. Therefore, the spherical food dough P2 before being supplied to the pressing roller 33 is preliminarily formed into an oval shape so that the spheroidized food dough has a disk shape when flattened by the pressing roller 33. Is formed between the dough spheroidizing device 5 and the flattening device 31, and the short diameter direction of the oblong food dough is supplied to the pressing roller 33. The direction changing means 41 for changing the directionality of the food dough is provided so as to be in the direction to do.

  More specifically, on the downstream side of the dough spheroidizing device 5, a transport conveyor 43 that transports the spherical food dough P <b> 2 after the spheronization process (rounding process) is connected to the transport belt conveyor 7. It is provided. Above the transport conveyor 43, a pair of lifting belts 45 for regulating the both sides of the spherical food dough P2 transferred from the transport belt conveyor 7 in the transport direction to form an oval shape long in the transport direction. Are rotatably provided. A regulating roller 47 that regulates the thickness of the food dough is rotatably provided slightly downstream of the lifting belt 45.

  As shown in FIG. 4, the direction changing means 41 has a configuration in which the transport direction of the transport conveyor 43 and the transfer (transport) direction of the supply conveyor 35 intersect so as to be orthogonal to each other. The food dough is transferred onto the supply conveyor 35. When the transport conveyor 43 and the supply conveyor 35 are arranged in a straight line, a swiveling means such as a swivel table that can be swiveled horizontally is disposed between the transport conveyor 43 and the supply conveyor 35 for transport. After the food dough is carried from the conveyor 43 onto the swiveling means, the food dough is carried out onto the supply conveyor 35 after the swiveling means is turned 90 °, whereby the direction of the food dough is 90 °. It is also possible to adopt a configuration for conversion.

  As a means for making an oval shape instead of the lifting belt, an oval shape can be formed on the supply conveyor 35. In other words, the food dough transferred to the supply conveyor can be clamped by pressing plates from both sides in the conveying direction to form an oval shape.

  With the above configuration, the spherical food dough P2 transferred from the dough spheroidizing device 5 onto the transport conveyor 43 is introduced between the pair of lifting belts 45 when transported (transported) downstream by the transport conveyor 43. Then, both sides in the transfer direction are restricted by pressing, so that an oval shape that is long in the transfer direction is formed. The thickness is regulated to be substantially constant by passing under the regulation roller 47. That is, the food dough P3 that has passed between the pair of lifting belts 45 and the lower side of the regulation roller 47 is formed in an oval shape in which the transport direction by the transport conveyor 43 has a long diameter.

  The food dough P3 transferred from the transport conveyor 43 onto the supply conveyor 35 is arranged so that the transfer direction of the supply conveyor 35 coincides with the minor axis direction of the food dough P3, in other words, with respect to the transfer direction. The food dough P3 is placed so that the major axis direction of the food dough P3 is orthogonal.

  Therefore, the oval food dough P3 formed in the oval shaper 33 is supplied between the pair of pressing rollers 33 after the transfer direction is changed by 90 °. When the food dough P3 is sandwiched between the pair of pressing rollers 33, in order to prevent the food dough P3 from being displaced so as to be inclined with respect to the transfer direction, for example, an upstream position close to the pressing roller 33 is provided. A regulating roller 49 that presses the food dough P3 between the food conveyor P3 and the supply conveyor 35 is rotatably provided. On the outer peripheral surface of the regulating roller 49, protrusions for effectively preventing the displacement of the food dough P3, for example, annular protrusions 49A are provided at appropriate intervals.

  With the above configuration, when the food dough P3 is flattened by the pair of pressing rollers 33, the food dough P3 is supplied to the pressing roller 33 in a state in which the displacement is restricted by the restriction roller 49. The dough P3 is flattened in a state where the minor axis direction of the dough P3 and the supply direction substantially coincide with each other. Therefore, when the food dough P3 is flattened, if the food dough P3 is extended in the transfer direction, the short diameter is increased, and the flattened food dough P4 is substantially circular.

  By the way, since the inner packaging material (inner material) is supplied onto the food dough P4 flattened into a disk shape, and the inner material is wrapped, the food (product) is manufactured. The crease formed on the lower surface of the spherical food dough P2 when the rectangular food dough P1 is spheroidized is located on the lower surface of the flattened food dough P4. Therefore, when a product (food) is manufactured as described above, the wrinkle portion is located outside the product, which is not desirable for improving the appearance.

  Therefore, it is desirable to provide an upside down means for turning the food dough upside down before supplying the inner material onto the food dough P4 so that the wrinkle portion is inside the product. As the upside down means, the food dough P3 is transferred from the dough spheroidizing device 5 onto the conveying conveyor 43 of the oval shaping device 39, and the food dough P3 is transferred from the conveying conveyor 43 onto the supply conveyor 35. It can be provided at a desired location such as a location before the inner material is supplied onto the transfer material or the food dough P4 flattened into a circular shape.

  For example, when the flattened food dough P4 is turned upside down, the food dough P4 is transferred into a reversing conveyor provided with a clamp conveyor (not shown) opposed to the top and bottom, and the food dough P4 is moved by the upper and lower clamp conveyors. The food dough P4 can be turned upside down by adopting a configuration in which the food dough P4 is fed out after being turned upside down in the sandwiched state. The rotation center of the reversing conveyor is an axis parallel to the transfer direction of the food dough P4, so that the rotation direction of the clamp conveyor is kept constant and the food dough P4 is turned upside down while being transferred. It can be done.

  In addition, when transferring the food dough P2 from the dough spheroidizing device 5 onto the conveying conveyor 43 of the oval shaping device 39, or when transferring the food dough P3 from the conveying conveyor 43 onto the supply conveyor 35, the food dough As a configuration for reversing the top and bottom of P2 or P3, the configuration of a reversing conveyor as described above can be employed. Moreover, it can be set as the structure reversed at the time of fall using a head. The upside down means only needs to be turned upside down so that the above-mentioned wrinkle portion is on the upper side, and may be provided at one place as appropriate.

  The disk-shaped food dough P4 flattened in the flattening device 31 is transferred to the food production device 51 (see FIGS. 1 and 5), and is supplied onto the food dough P4 in the food production device 51. After being sealed so as to wrap the inner material, it is placed on a transport conveyor as an example of a food receiving member and transported to the next process so that the sealed portion is on the lower side.

  As shown in FIG. 5, the food manufacturing apparatus 51 includes a frame body frame 53. A plurality of sprockets 55 rotatably provided on the frame body frame 53 includes a pair of front and rear endless chains 57 (see FIG. 6). ). A plurality of rectangular support frames 59 are arranged at equal intervals between the pair of endless chains 57, and both front and rear ends of each support frame 59 are supported by the endless chains 57. In other words, the support frame 59 is provided in an endless chain shape.

  The upper side of the endless chain 57 is provided so as to run horizontally in the left-right direction (left-right direction in FIGS. 5 and 6), and the chain guide 61 provided horizontally on the frame 53 (see FIG. 8). Is supported in a state in which the downward deflection is restricted. Further, rollers 59R are rotatably provided on both front and rear sides of the support frame 59. The rollers 59R are supported so as to be movable along guide rails 60 provided on the frame body frame 53.

  Inside the support frame 59, a pair of left and right pallets 65 </ b> A and 65 </ b> B in which semicircular concave portions are formed at positions facing each other so as to have a circular hole 63 in the joint portion are arranged to be openable and closable. The roller support members 67 provided at both front and rear ends of each of the pallets 65A and 65B are provided so as to get over the upper side of the support frame 59 when the support frame 59 is positioned on the upper side. A roller 69 is provided at the outer end of the member 67.

  The pair of pallets 65A and 65B are supported by the support frame 59 so that their joints can be opened and closed upward when the support frame 59 is positioned on the upper side. The pallets 65A and 65B The hole 63 provided in the joint is formed in a tapered shape so that the lower diameter is larger than the upper diameter. When the food dough is supplied into the hole 63, an endless support belt 71 (see FIG. 5) as an example of a support member for supporting the food dough from below is provided on the upper side of the support frame 59. It is provided below the horizontal moving part of the movably. The support belt 71 is provided so as to move in the same direction in synchronization with the movement of the support frame 59.

  At a position corresponding to the downstream end (left end in FIG. 5) of the support belt 71, a rotating body 73 that rotates in the same direction in synchronization with the rotation of the endless chain 57 is rotatably provided. A support base 75 as a support member for supporting the food dough in the hole 63 instead of the support belt 71 is provided on the outer periphery of 73 corresponding to the pitch of the holes 63 in the transfer direction. The support base 75 supports the food in the hole 63 so as not to fall inward when the support frame 59 is gradually moved from the upper side to the lower side by the rotation of the endless chain 57.

  On the outside of the support frame 59 that moves from the upper side to the lower side along the outer periphery of the rotating body 73, an arcuate guide rail 77 that guides the roller 69 provided in each of the pallets 65A and 65B from the outside is provided. It has been. Therefore, each pallet 65A, 65B is held in a closed state without being opened by a centrifugal force or the like. A pair of open / close guide rails 81A and 81B is provided between the lower side of the guide rail 77 and the lower guide rail 79 provided in the frame body frame 53 so as to be opened and closed downward. The open / close guide rails 81A and 81B are opened and closed by an appropriate actuator (not shown) such as a fluid pressure cylinder or a link mechanism.

  Therefore, when the rollers 69 provided on the pallets 65A and 65B come to the positions of the open / close guide rails 81A and 81B and are in an upside down state, the open / close guide rails 81A and 81B are shown in FIG. When the pallets 65A and 65B are opened downward, the pallets 65A and 65B are opened downward. Therefore, the product (food) in the hole 63 provided at the joint of the pallets 65A and 65B is dropped upside down and placed on the transport conveyor 83 serving as a receiving member disposed on the lower side. .

  In order to arrange and supply the food dough P4 formed in a disk shape by the flattening device 31 to a position corresponding to the hole 63 provided in the joint portion of the pallets 65A and 65B, the arrange conveyor 85 (FIG. 5).

A plurality of laterally moving conveyors 87 are provided corresponding to the number of rows of food dough P3 carried out from the flattening device 31 (two rows in this example).

  Each of the laterally moving conveyors 87 is individually laterally moved (moving in the front-rear direction and the direction orthogonal to the conveying direction) by the operation of an appropriate actuator. The lateral movement of each lateral movement conveyor 87 is performed as follows. That is, the width dimension in the front-rear direction (width direction) of each food dough P4 is detected by each width sensor 89 provided above the carry-out conveyor 37, and the center position in the width direction of each food dough P4 is calculated by the control device 91. Is done. Thereafter, each control unit 91 receives each food dough P4 and transports the food dough P4 to a position where the center position of each food dough P4 coincides with the center position of the hole 63 provided at the joint of the pallets 65A and 65B. It is moved horizontally under the control of.

  A standby alignment conveyor 93 is provided on the downstream side of each laterally moving conveyor 87. The standby alignment conveyor 93 is temporarily in a standby state in a state where each food dough P3 is transferred from each lateral movement conveyor 87. The food doughs P4 transferred onto the standby alignment conveyor 93 are positioned in a state corresponding to the holes 63 of the pallets 65A and 65B, and the food doughs P4 are aligned in the transfer direction.

  As described above, when the food dough P4 is aligned on the standby alignment conveyor 93 and is in the standby state, the endless chain 57 is transferred to the downstream transfer conveyor 95 with the intermittent movement and timing. The transfer conveyor 95 covers the hole 63 at the joint portion of the pallets 65A and 65B, and is placed and supplied so that the center of the hole 63 and the center of the food dough P4 substantially coincide with each other.

  As described above, after the food dough P4 is placed on the pallets 65A and 65B, when the food dough P4 is positioned at the position of the contour shaping device 97 by intermittent movement, the outer shape of the food dough P4 is shaped into a more accurate circle. At the same time, the food dough P4 is positioned so that the center position of the food dough P4 and the center position of the hole 63 coincide more accurately.

  As shown in FIGS. 8 and 9, the external shaper 97 is provided with a lifting frame 99 that is long in the front-rear direction (left-right direction in FIG. 8) above the pallets 65A and 65B on the upper side. The elevating frame 99 is moved up and down by an appropriate elevating actuator (not shown) such as a cam mechanism or a fluid pressure cylinder, and the pallet 65A, which is stopped on the lower surface of the elevating frame 99, Circular shaping mechanisms 101 are provided at positions corresponding to the holes 63 provided in the joint portion of 65B.

  As shown in FIG. 9, the circular shaping mechanism 101 includes a plurality of regulating members 105 that are moved in the radial direction by an appropriate actuator 103 such as a fluid pressure cylinder. Each regulating member 105 is provided with an arc-shaped regulating surface 105F for forming the outer peripheral edge of the food dough P4 into a more accurate circle. The restricting members 105 are provided so as to be close to each other up to a position where the end portions of the adjacent restricting members 105 come into contact with each other or a position slightly separated when moving in the radial inward direction and approaching each other.

  Then, as shown in FIG. 10, in order to prevent the food dough P4 from protruding from between the regulating members 105 to the outside, the flexible projection preventing member 107 having one end fixed to the regulating member 105 is used. The end side (free end side) is slidably in contact with the restriction surface 105F of the adjacent restriction member 105. The protrusion preventing member 107 is made of a belt-shaped resin, and a fine uneven portion is formed on the inner surface (contact surface) that contacts the food dough P4 in order to prevent the food dough P4 from sticking. .

  With the above configuration, at the position of the external shaper 97, when the elevating frame 99 is lowered and the regulating members 105 and the like are in contact with the upper surfaces of the pallets 65A and 65B, the actuators 103 are actuated to operate the regulating members. When the member 105 is moved radially inward and moved closer to each other, the outer peripheral edge of the food dough P4 surrounded by the restricting members 105 and the protrusion preventing member 107 is pressed and gradually shaped into an accurate circular shape. And the center position of the food dough P4 and the center position of the hole 63 are positioned more accurately. At this time, since the food dough P4 is gradually reduced in diameter, a portion corresponding to the hole 63 enters into the hole 63 by its own weight, and a dent is generated.

  As described above, after the outer shape shaping device 97 shapes the outer shape of the food dough P4 into a more accurate circle and is positioned so that the center of the hole 63 and the center of the food dough P4 coincide, It is conveyed and positioned at a position corresponding to the inner packaging material supply device 109 that supplies the inner packaging material (inner material) by intermittent operation. The inner packaging material supply device 109 is moved up and down by the operation of a vertical movement mechanism 111 such as a cam mechanism or a fluid pressure cylinder, and serves to supply an appropriate amount of inner material into the depression formed in the food dough P4. It is. When supplying the inner material, it is desirable to press the peripheral portion of the food dough P4 against the pallets 65A and 65B. In addition, since a well-known structure can be employ | adopted as the inner packaging material supply apparatus 109, the description about a more detail is abbreviate | omitted.

  As described above, the food dough P4 after the inner material is supplied by the inner packaging material supply device 109 is then positioned at a position corresponding to the envelope forming device 113, and the food dough is placed on the upper side of the inner packaging material so as to wrap the inner packaging material. The dough P4 is sealed. This foreskin forming apparatus 113 includes an elevating frame 117 (see FIGS. 11 and 12) that is moved up and down by an appropriate vertical moving mechanism 115 (see FIG. 5), and the elevating frame 117 is located at a position corresponding to the hole 63. Includes a shutter mechanism 119.

  The shutter mechanism 119 includes a housing 121 attached to the elevating frame 117, and a ring gear 123 is rotatably mounted in the housing 121. Around the ring gear 123, a plurality of pinion gears 125 meshing with the ring gear 123 are rotatably provided. The rotating shaft 127 integral with the pinion gear 125 has shutter pieces 129, respectively. Is integrally provided. Each of the shutter pieces 129 is configured to reduce the diameter of the region surrounded by each of the shutter pieces 129 by swinging while maintaining a state in which the tip portion is in contact with the side surface of the adjacent shutter piece 129. .

  In order to rotate the ring gear 123, a lever 131 is attached to the rotation shaft of the pinion gear 125A, and a connecting rod 135 reciprocated by the rotation of the motor 133 is pivotally supported at the tip of the lever 131. It is connected. The lever 137 provided in the adjacent shutter mechanism 119 and the lever 131 are pivotally connected via a connecting rod 139.

  Therefore, when the motor 133 is driven to rotate and the connecting rod 135 is reciprocated, the pinion gear 125A is reciprocated and the ring gear 123 is reciprocated. When the ring gear 123 is reciprocally rotated, each pinion gear 125 is reciprocated, the shutter piece 129 is reciprocated, and the space in the area surrounded by each shutter piece 129 is reduced in diameter. Therefore, when the peripheral part of the food dough P4 enclosing the inner material is collected and positioned in the upper part in the region, the collected peripheral part of the food dough P4 is pressed against the central part and sealed. . The protrusion formed at the time of sealing is pressed by a pressing member 117A (see FIG. 5) provided in the lifting frame 117 at a position moved to the downstream side by one step.

  In the above configuration, the operation of the overall configuration will be described with reference to FIGS. 1 and 13 schematically and conceptually showing the overall configuration.

  When the food dough piece P1 is supplied from the food dough supply device 1 to the dough spheroidizing device 5, the rectangular food dough piece P1 is spheroidized (rounded) in the molding cup 21 as described above. The spheroidized food dough P2 is formed into an oval food dough P3 in the oval shaper 39 and transferred onto the supply conveyor 35, whereby the direction of transfer of the food dough P3 is changed. Converted.

  The food dough P3 is flattened by the flattening device 31 into a disk-shaped food dough P4. At this time, the direction of the tensile stress applied to the food dough P2 in the dough spheroidizing device 5 is flattened so as to be the radial direction in the food dough P4 as described above. The food dough P4 is placed at a position corresponding to the hole 63 of the pallets 65A and 65B as described above. In FIG. 13, the standby alignment conveyor 93 and the lateral movement conveyor 87 are shown in an integrated manner.

  The food dough P4 placed on the pallets 65A and 65B has been turned upside down by the upside down means disposed at an appropriate position as described above. The food dough P4 is positioned so that the outer shape is formed into a more accurate circular shape at the position of the outer shape shaping device 97, and the center of the hole 63 and the center of the food dough P4 coincide. Then, the supply of the inner packaging material (inner material) is received at the position of the inner packaging material supply device 109, and then it is transferred to the position of the envelope forming apparatus 113, and sealed with the food dough P4 so as to wrap the inner material. At this time, since the food dough P4 is positioned so that the center position of the food dough P4 coincides with the center position of the hole 63, the food dough P4 is given a tensile stress in the radial direction. The parts are converged almost uniformly on the upper side of the inner material and sealed by the shutter mechanism.

  When the food dough P4 is sealed as described above, the food dough P4 is stretched in the direction of the tensile stress, so that the food dough P4 can be smoothly and uniformly stretched. It can stop well. As described above, when the inner material is wrapped by the food dough P4, the sealing portion is on the upper side, and the protrusion P is formed on the upper portion of the product (food). The protrusion P is pressed by a pressing member 117A provided on the lifting frame 117 in the foreskin forming apparatus 113.

  Thereafter, the product is transferred to the lower side, and the pallets 65A and 65B are opened, so that the product is turned upside down and placed on the transfer conveyor 83 and transferred to the next process.

  By the way, conventional bread production requires a dough recovery process (intermediate fermentation equipment / overhead puller) in which the conveyor is routed after the dough is divided and rounded. Will disappear. In addition, in intermediate fermentation, the rounded dough is processed by being placed randomly on the conveyor in the up / down / left / right directions, so the direction of stress of the dough cannot be grasped, and the quality of the dough is not stable.

  However, in this example, as understood from the above description, when the food dough piece is spheroidized, it is spheroidized by applying a tensile stress in the meridian direction of the spheroid, and it continues without rest. When flattened, the tensile stress is in the radial direction (radial direction). And when wrapping the inner material supplied to the center, the cloth is stretched in the tensile stress direction. That is, the foreskin-formed dough has a uniform stress in the meridian direction (there is tension), so that it is balanced as a spherical body, and the epidermis is smooth and has no irregularities as the final product after final fermentation and firing. It can be made into a shape without distortion.

  Therefore, this example can have an excellent effect as compared with the conventional example.
