It is provided with four guide plates 51 (a total of eight) fixed to the moving plate 49. The swing arm 47 is interlocked with the drive shaft 40 via a power transmission mechanism (not shown) such as a link mechanism provided in the base housing 41. Therefore, the guide plates 51 facing each other approach and separate from each other as the swing arms 47 swing in synchronization.

The pair of plywood 44s are provided with a support shaft 44B and a support shaft 44C on both side surfaces 44A orthogonal to the longitudinal direction (left-right direction in FIG. 1). The two pairs of support shafts 44B provided on the opposite sides (upper and lower center sides in FIG. 2) of the pair of plywood 44s are rotatably pivotally supported and connected to the connecting member 42 attached to the base housing 41.

It is fitted freely. Therefore, when the opposing guide plates 51 approach and separate from each other, the outside of the plywood 44 swings around the support shaft 44B.

Here, when the opposing guide plates 51 are separated from each other, a pair of plywood 44s are arranged in a substantially V shape, and the mounting surface 44D of the plywood 44 is oriented upward. The mounting surface 44D of the plywood 44 is arranged along the vertical direction when the opposing guide plates 51 are close to each other, which is referred to as the open state of the plywood 43, and the mounting surface of the pair of plywood 44 is arranged. The state in which the 44Ds face each other is referred to as a closed state of the inclusion unit 43.

Further, the plywood 44 is provided with a recess 44E on a side surface facing the plywood 44 that is orthogonal to and faces the side surface 44A. When the encapsulation unit 43 is in the open state, the opposing recesses 44E form an oval opening 43A in the center of the encapsulation unit 43 composed of a pair of encapsulation plates 44. Further, an inclined surface 44F is formed from the mounting surface 44D to the recess 44E.

The pressing device 27 is arranged above the inclusion device 25. The pressing device 27 includes a pressing member 63 and a pressing device 65 corresponding to each inclusion unit 43 on an elevating frame 28 that can be raised and lowered. The elevating frame 28 is provided inside the base 39 so as to be elevated by a known elevating mechanism interlocked with a driving means such as a servomotor.

The pressing member 63 is attached to the lower surface of the elevating frame 28. The pressing member 63 has a cup shape with an opening 63A below, and includes an annular peripheral wall 63B and a ceiling portion 63C that closes the upper portion of the peripheral wall 63B. Further, a pressing surface 63D inclined in a V shape is formed on the lower end surface of the pressing member 63. One inclined pressing surface 63DA and the other inclined pressing surface 63DB of the pressing surface 63D are formed so as to be parallel to the mounting surface 44D of each encapsulating plate 44 when the encapsulation unit 43 is in the open state. Further, at the lowermost end of the pressing member 63, a ridge portion 63E protruding from the left and right inclined pressing surfaces is formed.

The pressing member 63 is provided with two through holes 63F penetrating the peripheral wall 63B, and the pipe joint 64 is screwed into the pressing member 63. By communicating the compressor 61 with the pipe joint 64, the compressed air A2 is sent out to the hollow internal space 63S of the holding member 63. In this case, a compressed air supply device such as a compressor 61 is a device for increasing the air pressure in the internal space 63S of the pressing member 63 to raise the air pressure, and is a bowl-shaped forming device for forming the outer skin material D in a bowl shape together with the pressing member 63.

The pushing member 68 moves up and down inside the holding member 63 by operating the actuator 67 (see FIG. 4).

The support device 29 is a belt conveyor that is arranged below the inclusion device 25, supports the exodermis material D, and further conveys the packaged food P to the carry-out conveyor 31, which will be described later. The support device 29 is intermittently driven by the endless conveyor belt 29A being hung around a plurality of rollers. The support device 29 is provided so as to be able to move up and down independently of the pressing device 27 by interlocking with a drive means such as a servomotor. The elevating position and elevating speed of the support device 29, and the driving timing and driving speed of the belt conveyor 29A are adjustable and controlled.

The carry-out conveyor 31 is a belt conveyor continuously provided on the downstream side of the support device 29 that has descended to the descending end position. The carry-out conveyor 31 is a device that receives the packaged food P from the support device 29 and further carries it out to the downstream side.

Next, the molding process of the packaged food P by the molding apparatus 1 according to the first embodiment of the present invention will be described with reference to FIGS. 4 to 9. The side views shown in FIGS. 4 to 9 are explanatory views conceptually showing the central portion of one of the inclusion units 43 as viewed from the downstream side of the transport. The dough ball DB is divided into a required weight from a mass of food dough, rolled and molded, and then laid indoors for a required time to be adjusted. The dough ball DB is spread by the spreading device 101, and the exodermis material D is formed in a circular and flat shape. For the outer skin material D, the width W of the outer skin material D is measured by the aligning device 103 arranged between the spreading device 101 and the inner material supply device 3, and the center position in the width direction is the discharge port 17 of the nozzle 15. After being aligned so as to match the lower position, the material is supplied to the belt conveyor 7 of the inner material supply device 3. The belt conveyor 7 aligns the outer skin material D at a position where the center of the length L of the outer skin material D coincides with the center of the discharge port 17 based on the command from the control device 33, and temporarily stops the belt conveyor 7.

When the transportation of the outer skin material D is stopped, the nozzle 15 descends to a required position, the feeding device 11 feeds the inner material F into the nozzle 15, and the on-off valve descends in the nozzle 15 from the discharge port 17. The required amount of inner material F is discharged. Then, as the nozzle member 15 rises, the on-off valve rises in the nozzle 15. At this time, compressed air A1 is ejected from the air outlet of the on-off valve. The inner material F is separated from the nozzle 15 and placed on the upper surface of the outer skin material D (inner material mounting step). The outer skin material D on which the inner material F is placed is conveyed by the belt conveyor 7 to the supply conveyor 23 of the bi-fold forming apparatus 5.

The tip end 35 of the supply conveyor 23 is in a standby position that contracts upstream in the range of reciprocating movement. When the outer skin material D is detected by the sensor 37, the tip portion 35 moves to the downstream side along the transport direction R. This moving speed is set to be the same as or slightly faster than the carrying speed of the supply conveyor 23. The tip portion 35 stops moving at an advancing position extending so as to cover the upper part of the inclusion unit 43 arranged on the downstream side. Then, at a position where the center of the outer skin material D coincides with the center of the opening 43A of the inclusion unit 43, the belt conveyor 7 and the supply conveyor 23 stop the transportation of the outer skin material D (see FIG. 4).

Next, the tip portion 35 retracts at a stretch, and the exodermis material D placed on the tip portion 35 is transferred to the mounting surface 44D of the wrapping plate 44 configured in the wrapping unit 43. Further, the next outer skin material D on which the inner material F is placed is transferred to the inclusion unit 43 arranged on the upstream side and in the open state. At this time, even if the inner material F falls on the plywood 44 in a state of being displaced from the center of the opening 43A of the bundling unit 43, the pair of plywood 44 is gently inclined in a substantially V shape. Therefore, the outer skin material D slides so that the inner material F fits inside the opening 44 in a plan view, and the center of the outer skin material D is aligned with the center of the opening 43A (transfer step, see FIG. 5).

When the tip portion 35 retracts to the standby position at the upstream end, the elevating frame 28 of the pressing device 27 is lowered, so that the pressing member 63 is lowered toward the inclusion unit 43. The lowering stop position of the pressing member 63 is controlled so as to be appropriately adjustable according to the thickness and hardness of the outer skin material D. The pressing surface 63D at the lower end of the pressing member 63 presses the peripheral edge DE of the outer skin material D to the plywood 44, and seals the peripheral edge DE with the plywood 44 (pressing step, see FIG. 6). Further, the ridge portion 63E formed in the center of the pressing surface 63D of the pressing member 63 forms a groove portion DF which is a crease on the upper surface of the peripheral edge portion DE of the outer skin material D. Then, compressed air A2 is supplied from the compressor 61 to the inside of the pressing member 63 for the required time T, and acts to increase the air pressure inside the pressing member 63. The outer skin material D inside the pressing surface 63D at the lower end of the pressing member 63 (inside the opening 63A of the pressing member 63) expands downward (recessed) inside the opening 43A due to the air pressure of the compressed air A2, and finally. Is formed in a bowl shape, and the inner material F is arranged in the bowl-shaped portion of the exodermis material D (bowl-shaped forming step, inner material arranging step, see FIG. 7). The intermediate position portion of the exodermis material D formed in a bowl shape is held by the inner peripheral surface and the inclined surface 44F of the opening 43A, and the lower portion of the exodermis material D bulges downward from the inclusion unit 43.

The support device 29 stands by at a required interval from the plywood 44 below the wrapping device 25. By supporting the bottom of the outer skin material D in which the upper surface of the conveyor belt 29A of the support device 29 expands downward, the outer skin material D is prevented from being deformed more than necessary, and the shape of the outer skin material D is stabilized. (Support process, see FIG. 7). At this time, the ascending / stopping position of the support device 29 determines the position of the head FT of the inner material F with respect to the peripheral edge DE of the outer skin material D held by the pressing member 63 on the mounting surface 44D of the plywood 44. Become. The position of the head FT is preferably lower than the uppermost position of the pressing member 63 on the pressing surface 63D, and the fabric on the peripheral edge of the outer skin material D that is not in contact with the inner material F is sufficient to wrap the inner material F. It is desirable that the amount is placed on the mounting surface 44D of the plywood 44 (including a part of the inclined portion 44F in this embodiment).

The pressing member 63 is raised together with the elevating frame 28, and the closing operation of the inclusion unit 43 is started. The guide plates 51 of the drive mechanism 45 approach each other, and each plywood 44 swings around the support shaft 44B, and the peripheral edge DE of the outer skin material D mounted on the mounting surface 44D of each plywood 44 is a groove DF. Fold it in half and overlap it. The mounting surfaces 44D of the pair of plywood 44 are stopped in the vertical direction, the peripheral edge DE of the outer skin material D is sealed between the mounting surfaces 44D facing each other, and the packaged food P is formed. (Seal process, see FIG. 8).

When the plywood 44 closes, the recess 44E of the plywood 44 moves upward while leveling the upper part of the inner material F via the outer skin material D, and the opposing inclined portion 44F moves to the peripheral portion DE of the outer skin material D. The shoulder PA of the packaged food P connected to the above is pressed to form a mold. Further, the wrapping plate 44 of the wrapping unit 43 in the closed state is in a state in which the recess 44E faces downward and is separated from the support device 29. The lower portion of the side portion of the packaged food P is arranged in this space, and the lower portion of the packaged food P is not sandwiched by the plywood 44. Therefore, the action of the recess 44E suppresses the formation of a gap between the inner material F and the outer skin material D, and the inner material F can be wrapped without leaking to the outside from the sealed portion of the outer skin material D. , The packaged food P is stably molded. Further, the inner material F can be pushed downward inside the packaged food P by the action of the inclined portion 44F, and the shape of the shoulder portion PA of the packaged food P can be reliably formed.

The plywood 44 is swung in the opposite direction, the bundling unit 43 is opened, and the plywood 44 releases the food P to be wrapped. The support device 29 descends to convey the packaged food P to the carry-out conveyor 31. Further, the elevating frame 28 of the pressing device 27 is lowered to the lowered position again, and the actuator 67 of the pushing device 65 is operated to lower the pushing member 68. Even when the packaged food P adheres to the plywood 44, the embedding food P can be reliably transferred to the support device 29 by pushing the packaged food P downward by the pressing member 68 ( Mold release process, see FIG. 9). Then, the packaged food P is transferred from the support device 29 to the carry-out conveyor 31, and further carried out to a secondary molding device, a heat treatment device, or the like (carry-out process).

Next, the molding apparatus 201 of the packaged food P according to the second embodiment of the present invention will be described with reference to FIGS. 10 to 14. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The molding device 201 includes a spreading device 101, an aligning device 103, and a two-fold molding device 205. The two-fold molding device 205 includes a supply conveyor 23, an inclusion device 25, a pressing device 227, a support device 29, a unloading conveyor 31, and a control device 33 for controlling each of these devices on the base 39.

The holding device 227 is arranged above the inclusion device 25. The pressing device 227 includes an elevating frame 28 that can be raised and lowered, a holding member 63 corresponding to each inclusion unit 43, and an inner material supply device 203. The inner material supply device 203 includes a discharge unit 209 for supplying the inner material F so as to be arranged on the outer skin material D, and a supply device 211 for supplying the inner material F to the discharge unit 209.

The discharge unit 209 includes a tubular nozzle 215 and a piston 217 that moves up and down inside the nozzle 215. The upper end of the piston 217 is connected to a linear actuator 67. Further, a discharge port 215A is formed at the lower end of the nozzle 215, and a supply port 215B communicating with the feeding device 211 is provided on the peripheral surface of the nozzle 215. Therefore, the discharge port 217A and the supply port 217B are opened and closed by the vertical movement of the piston 217. The discharge unit 209 intermittently discharges the required amount of the inner material F from the discharge port 215A by interlocking the feeding device 211 that intermittently feeds the inner material F with the piston 217 that opens and closes the discharge port 215A. .. Further, the piston 217 is provided with an air ejection port 217A that ejects compressed air A1 in order to separate the discharged inner material F from the nozzle 215. In this case, the inner material supply device 203 becomes a bowl-shaped forming device that forms the outer skin material D in a bowl shape by the discharge pressure for discharging the inner material F.

The pressing member 63 is integrally provided in the lower part of the nozzle 215. The pressing member 63 has a cup shape having an opening 63A at the bottom, and the lower end of the nozzle 215 is formed in the center of the ceiling portion 63C that closes the annular peripheral wall 63B. The pressing member 63 is connected to the elevating frame 28 via the nozzle 215, and the movable position of elevating and lowering is controlled so as to be adjustable.

Next, the molding process of the packaged food P by the molding apparatus 201 according to the second embodiment of the present invention will be described. The dough ball DB is spread by the spreading device 101, and the exodermis material D is formed in a circular and flat shape. The outer skin material D is conveyed to the supply conveyor 23 after the width W of the outer skin material D is measured by the alignment device 103 and the center position in the width direction is aligned with the lower position of the discharge port 215A of the nozzle 215. (See FIG. 12 (a)).

Based on the detection signal of the sensor 37, the outer skin material D is transferred to the inclusion unit 43 in the open state, which is arranged on the downstream side by the retracting operation of the tip portion 35 of the supply conveyor. Further, the next exodermis material D is transferred to the inclusion unit 43 arranged on the upstream side and in the open state. At this time, since the pair of plywood 44s are gently inclined in a substantially V shape, the outer skin material D is slightly folded in half, and the central portion of the outer skin material D is slightly in the opening 43A of the inclusion unit 43. By entering, it becomes dented (relocation process, see FIG. 12 (b)).

When the tip portion 35 retracts to the standby position at the upstream end, the elevating frame 28 of the pressing device 227 is lowered, so that the pressing member 63 is lowered toward the inclusion unit 43 and stops at the set position. The pressing surface 63D at the lower end of the pressing member 63 presses the peripheral edge DE of the outer skin material D to the plywood 44, and seals the peripheral edge DE with the plywood 44 (see the pressing step, FIG. 13A). Then, the inner material F is extruded from the nozzle 215 of the inner material supply device 203 to the central portion of the outer skin material D. The outer skin material D expands downward (dents) inside the opening 43A due to the discharge pressure of the inner material F from the nozzle 215, and is finally formed in a bowl shape, and is inside the bowl-shaped outer skin material D. The material is arranged (see bowl-shaped forming process, inner material arrangement process, FIG. 13 (b)). The intermediate position portion of the exodermis material D formed in a bowl shape is held by the inner peripheral surface of the opening 43A, and the lower portion of the exodermis material D bulges downward from the inclusion unit 43. Then, the support device 29, which stands by from the plywood 44 at a required interval, supports the bottom portion of the expanding outer skin material D (see the support process, FIG. 13B).

When the pressing device 227 rises together with the elevating frame 28, the compressed air A1 is ejected from the air ejection port 217A of the piston 217 of the inner material supply device 203 to prevent the inner material F from adhering to the nozzle 215. After the pressing member 63 is raised, the encapsulation unit 43 starts a closing operation to form the packaged food P (seal step, see FIG. 14A). The plywood 44 is swung in the opposite direction, the bundling unit 43 is opened, and the plywood 44 releases the food P to be wrapped. The support device 29 descends to convey the packaged food P to the carry-out conveyor 31 (see the mold release step, FIG. 14B). At this time, the pressing device 227 can be lowered to the lowering position again, and the compressed air A1 can be ejected from the air ejection port 217A. Even when the packaged food P adheres to the plywood 44, the compressed air A1 pushes the packaged food P downward so that the packaged food P can be reliably transferred to the support device 29. Then, the packaged food P is transferred from the support device 29 to the carry-out conveyor 31, and further carried out to a secondary molding device, a heat treatment device, or the like (carry-out process).

Next, the molding apparatus 301 of the packaged food P according to the third embodiment of the present invention will be described with reference to FIGS. 15 to 19. The same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The molding device 301 includes a spreading device 101, an alignment device 103, and a two-fold molding device 305. The two-fold molding device 305 has a configuration in which the holding device 227 of the above-mentioned two-fold molding device 205 is replaced with the holding device 327.

The pressing device 327 provided in the two-fold molding apparatus 305 includes a pressing member 63 and an inner material supply device 303 corresponding to each inclusion unit 43. The inner material supply device 303 includes a discharge unit 309 that supplies the inner material F so as to be arranged on the outer skin material D, and a supply device 211 that supplies the inner material F to the discharge unit 309. The pressing member 63 is attached to the lower surface of the elevating frame 28 and is provided so that the elevating position can be adjusted. Further, the discharge unit 309 is provided so as to move up and down together with the pressing member 63, and the raising and lowering position can be adjusted by an independent raising and lowering mechanism 316 separate from the raising and lowering frame 28.

The discharge unit 309 is provided with a tubular nozzle 315 and a valve member 317 that moves up and down inside the nozzle 315 to open and close the discharge port 315A of the nozzle 315. The upper end of the valve member 317 is connected to a linear actuator 318. Further, the valve member 317 is connected to a power transmission mechanism such as a gear train to a rotary actuator 319 and is provided so as to be rotatable in the circumferential direction.

The nozzle 315 penetrates the elevating frame 28 and the ceiling portion 63C of the pressing member 63 and reaches the inside of the pressing member 63. The nozzle member 315 moves up and down inside the pressing member 63 by operating the actuator 318. In this case, the nozzle 315 is a bowl-shaped forming device that pushes the central portion of the outer skin material D downward as a pushing device to form the outer skin material D in a bowl shape.

Next, the molding process of the packaged food P by the molding apparatus 301 according to the third embodiment of the present invention will be described. The dough ball DB is spread by the spreading device 101, and the exodermis material D is formed in a circular and flat shape. The outer skin material D is conveyed to the supply conveyor 23 after the width W of the outer skin material D is measured by the alignment device 103 and the center position in the width direction is aligned with the lower position of the discharge port 315A of the nozzle 315. (See FIG. 15 (a)).

Based on the detection signal of the sensor 37, the outer skin material D is transferred to the inclusion unit 43 arranged on the downstream side and in the open state by the retracting operation of the tip portion 35 of the supply conveyor (transfer step, FIG. 15 (b). )reference). Further, the next exodermis material D is transferred to the inclusion unit 43 arranged on the upstream side and in the open state. At this time, since the pair of plywood 44s are gently inclined in a substantially V shape, the outer skin material D is slightly folded in half, and the central portion of the outer skin material D is slightly in the opening 43A of the inclusion unit 43. It will be dented by entering.

When the tip portion 35 retracts to the standby position at the upstream end, the pressing member 63 and the nozzle 315 of the pressing device 327 are lowered at the same time. First, the pressing surface 63D at the lower end of the pressing member 63 presses the peripheral edge DE of the outer skin material D to the plywood 44, and seals the peripheral edge DE with the plywood 44 (see the pressing step, FIG. 16A). .. Then, the nozzle 315 of the inner material supply device 303 passes through the opening 43A of the inclusion unit 43 and descends to push the central portion of the outer skin material D downward from the opening 43A, and the center of the outer skin material D is formed in a bowl shape. (See bowl-shaped forming step, FIG. 16 (b)).

The nozzle 315 rises and discharges the inner material F from the discharge port 315A into the bowl-shaped outer skin material D (see bowl-shaped forming step, inner material arranging step, FIG. 17A). The lower end of the nozzle 315 temporarily stops rising near the upper end of the opening 43A, and the valve member 317 descends in the nozzle 315 to close the discharge port 317A, so that the discharge of the inner material F is completed and the outer skin is finished. The inner material F is arranged in the material D (see bowl-shaped forming step, inner material arranging step, FIGS. 17 (b) and 19 (a)). At this time, the feeding of the inner material F from the feeding device 211 is temporarily stopped. Then, the support device 29, which stands by from the plywood 44 at a required interval, supports the bottom portion of the expanding outer skin material D (see the support process, FIG. 17B).

The valve member 317 rises in the nozzle 315 by the actuator 318 while rotating in the circumferential direction by the actuator 319 (see FIG. 19 (b)), and then the nozzle 315 rises (see FIG. 19 (c)). Further, after the pressing member 63 is raised, the encapsulation unit 43 starts a closing operation to form the packaged food P (seal step, see FIG. 18A). The plywood 44 is swung in the opposite direction, the bundling unit 43 is opened, and the plywood 44 releases the food P to be wrapped. The support device 29 descends to convey the packaged food P to the carry-out conveyor 31 (see the mold release step, FIG. 18B). At this time, the pressing member 63 is lowered again, and it is possible to supply the compressed air A1 to the inside of the pressing member 63 as in the first embodiment. Even when the packaged food P adheres to the plywood 44, the compressed air A1 pushes the packaged food P downward so that the packaged food P can be reliably transferred to the support device 29. Then, the packaged food P is transferred from the support device 29 to the carry-out conveyor 31, and further carried out to a secondary molding device, a heat treatment device, or the like (carry-out process).

Next, the molding apparatus 401 of the packaged food P according to the fourth embodiment of the present invention will be described with reference to FIGS. 20 to 24. The same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. The molding device 401 replaces the bi-fold molding device 5 in the above-mentioned molding device 1 with the bi-fold molding device 405. Specifically, the encapsulation device 25 is replaced by the encapsulation device 425, and the presser device 27 is pressed by the presser device 27. It was replaced with 427.

The wrapping device 425 of the bi-fold molding device 405 includes a base housing 441 and two sets of wrapping units 443. Each set of inclusion units 443 has the same configuration. Further, the encapsulation unit 443 is composed of a pair of encapsulation plates 444 having the same shape, and the pair of encapsulation plates 444 are provided so as to be swingable and close to each other. Further, each plywood 444 is provided so as to be swingable and reciprocate in the horizontal direction with respect to the base housing 441.

The pair of plywood 444s are provided with support shafts 411 on the side of the plywood 444 facing each other on both side surfaces 444A orthogonal to the longitudinal direction (Y-axis direction of FIG. 20). The support shaft 411 is rotatably supported by the bearing 413. The bearing 413 is provided so as to reciprocate in the horizontal direction (X-axis direction in FIG. 20) orthogonal to the longitudinal direction of the plywood 444. Specifically, of the pair of plywood 444, the support shaft 411A provided on the plywood 444W located on the downstream side of the transport is pivotally supported by the bearing 413A, and the support provided on the plywood 444Z located on the upstream side of the transport. The shaft 411B is pivotally supported by the bearing 413B. Further, the plywood 444 is provided with a recess 444E on the side surface facing the plywood 444 orthogonal to and facing the side surface 444A. When the inclusion unit 443 is in the open state (see FIGS. 20 and 21 (a)), the opposing recesses 444E form an oval opening 443A in the center of the inclusion unit 443 consisting of a pair of inclusion plates 444. To do. Further, an inclined surface 444F is formed from the mounting surface 444D to the recess 444E.

The inclusion device 425 includes a drive mechanism 445 that opens and closes and approaches and separates the inclusion unit 443. The drive mechanism 445 includes a slide mechanism 406 (406A, 406B), a link mechanism 407 (407A, 407B), and a clutch mechanism 408 (408A, 408B). The slide mechanism 406 is a power transmission mechanism that operates the link mechanism 407 and causes the clutch mechanism 408 to approach and separate from each other. The link mechanism 407 swings a pair of wrapping plates 444W and 444Z, respectively, to open and close the wrapping unit 443. Further, the clutch mechanism 408 switches between the opening / closing operation and the approach / detachment operation of the inclusion unit 443. Two sets of the slide mechanism 406, the link mechanism 407, and the clutch mechanism 408 are provided so as to be point-symmetrical in a plan view. Here, the front side (front side in the Y-axis direction of FIG. 20) will be described.

One slide mechanism 406A includes a swing arm 447, a shaft 471, and a block 473. The swing arm 447 is connected to the drive shaft 40 and is provided so as to swing horizontally. The shaft 471 is slidably supported in the X-axis direction on the upper surface of the base housing 441, is connected to the swing arm 447, and reciprocates. The block 473 is integrally fixed to the shaft 471, and a groove 473M is formed in the vertical direction on the side surface opposite to the mounting surface of the shaft 471.

One link mechanism 407A includes an arm 475, a shaft 477A, two arms 479A, a link plate 481A, and a cam follower 483. The arm 475 is integrally attached to the shaft end portion of the shaft 477A rotatably supported by the clutch mechanism 408A, and has a cam follower 483 on one end side. The cam follower 483 is slidably provided in the groove 473M of the block 473. One end of the link plate 481A is connected to the other end side of the arm 475. An arm 479A attached to a support shaft 411A of each plywood 444W is connected to each of the other end and the intermediate position of the link plate 481A.

In the other link mechanism 407B, the base end portion of the arm 476 is integrally attached to the other shaft end portion of the shaft 477B. One end of the link plate 481B is connected to the other end side of the arm 476. An arm 479B attached to a support shaft 411B of each plywood 444Z is connected to each of the other end and the intermediate position of the link plate 481B.

On the other hand, the clutch mechanism 408A is a mechanism that switches between a state in which the shaft 477A is engaged with the shaft 477A to fix the shaft 477A and stop the rotation, and a state in which the shaft 477A can be rotated by not engaging with the shaft 477A. The clutch mechanism 408 includes an engaging member that is operated by a driving means such as an actuator, but since it is a known technique, detailed description thereof will be omitted. The clutch mechanism 408A is connected to the bearing 413A by a joint 485A, and is provided so as to be reciprocating in the transport direction R (X-axis direction in FIG. 20) together with the plywood 444W. The other clutch mechanism 408B is provided in the same manner as the clutch mechanism 408A, and is provided so as to be able to reciprocate integrally with the joint 485B, the bearing 413B, and the inclusion plate 444Z. The clutch mechanism 408 with the shaft 477 fixed is operated by the slide mechanism 406, and the pair of plywood 444 approaches and separates from each other.

The pressing device 427 of the bi-fold molding device 405 is arranged above the wrapping device 425. The pressing device 427 includes an elevating frame 28 and a pressing member 463 corresponding to each inclusion unit 443. The pressing member 463 is attached to the lower surface of the elevating frame 28 and has a cup shape like the pressing member 63, and a pressing surface 463D is formed on the lower end surface of the pressing member 463. The pressing surface 463D is formed so as to be parallel to the mounting surface 444D of each horizontal wrapping plate 444 when the wrapping unit 443 is in the open state. Further, a ridge portion 463E protruding from the pressing surface 463D is formed at the lowermost end of the pressing member 463. Compressed air A2 is sent from the compressor 61 to the internal space 463S of the pressing member 463 via the pipe joint 64.

Next, the molding process of the packaged food P by the molding apparatus 401 according to the fourth embodiment of the present invention will be described with reference to FIGS. 21 to 24. The schematic views shown in FIGS. 21 to 24 are explanatory views relating to one of the inclusion units 443. The outer skin material D on which the inner material F is placed on the inclusion unit 443 in the open state (initial state, see FIG. 21) is transferred from the supply conveyor 23 (transfer process), and the outer skin material D is transferred by the lowering pressing member 463. The peripheral edge DE of the above is pressed against the plywood 444 (pressing step). Then, by sending compressed air A2 to the internal space 463S of the pressing member 463 to increase the air pressure, the outer skin material D expands downward from the opening 443A of the inclusion unit 443, and the bottom portion of the outer skin material D is supported by the support device 29. The outer skin material D is formed in a bowl shape (supporting step, bowl-shaped forming step, inner material arranging step).

After that, the swing arm 447 of the slide mechanism 406 starts swinging, and the shaft 471 and the block 473 move in the X-axis direction of FIG. At this time, the clutch mechanism 408 is not engaged with the shaft 477 and makes the shaft 477 rotatable. The arm 475 swings around the shaft 477A when the cam follower 483 moves in conjunction with the block 473. Along with this, the link plate 481A and the arm 479A operate, and the plywood 444W swings in the closing direction around the shaft 411A. In synchronization with this, the link mechanism 407B operates, and the plywood 444Z swings in the closing direction around the shaft 411B (see FIG. 22). The peripheral edge DE of the outer skin material D is folded in half and overlapped, and is brought into close contact between the facing mounting surfaces 444D to form the packaged food P (sealing step, see FIG. 22).

When the inclusion unit 443 completes the closing operation, the clutch mechanism 408 engages with the shaft 477, fixes the shaft 477 in the clutch mechanism 408, and stops the swing of the arm 475. After that, the slide mechanism 406A continues to operate, and the block 473 integrally moves the cam follower 483, the arm 475, the clutch mechanism 408A, the joint 485A, the bearing 413A, the support shaft 411A, and the inclusion plate 444W in the transport direction R. At this time, the clutch mechanism 408B also operates in synchronization, and by moving the wrapping plate 444Z to the transport upstream side opposite to the transport direction R, the wrapping plate 444W and the wrapping plate 444Z are separated from each other and the distance is widened. The packaged food P is released from the encapsulation unit 443 due to the separation and its own weight of the encapsulating plates 444W and 444Z, and is reliably transferred onto the support device 29 standing by below (release step, see FIG. 23). The packaged food P is transferred from the support device 29 to the carry-out conveyor 31, and further carried out to a secondary molding device, a heat treatment device, or the like (carry-out process).

After that, the clutch mechanism 408 switches the shaft 477 to a rotatable state, the swing arm 447 swings in the opposite direction, and the two plywood 444 swings in the open direction (see FIG. 24). After that, the clutch mechanism 408 switches the shaft 477 to the stopped rotation state, the two plywood 444 approach each other, and return to the open state (initial state).

In the above embodiment, the opening / closing operation of the wrapping unit 443 and the approaching / separating operation of the pair of wrapping plates 444 are described as a configuration in which the clutch mechanism 408 is provided and one driving means is used. It is also possible to use another drive means. In this case, the clutch mechanism 408 becomes unnecessary.

Further, in the above embodiment, the pair of plywood 444s are described as having both approaching and separating operations, but it is also possible that only one of the pair of plywoods 444 performs the approaching and separating operations.

As can be understood from the above description, according to the present invention, when the encapsulation unit 43 (443) composed of a pair of encapsulation plates 44 (444) is in the open state, the outer skin material D is used by the pressing member 63 (463). The peripheral portion DE of the above is pressed against the plywood 44 (444), and the bowl-shaped forming device (compressed air supply device in the pressing device 27, the inner material supply device 203 in the pressing device 227, the nozzle 315 which is the pushing device in the pressing device 327, and the pressing device). The compressed air supply device in the device 427) can extend the vicinity of the center of the outer skin material D downward from the opening 43A (443A) of the inclusion unit 43 (443) to form the outer skin material D in a bowl shape. Then, by closing the inclusion unit 43 (443), the peripheral edge DE of the outer skin material D on which the inner material F is arranged is folded in half and sealed between the facing mounting surfaces 44D (444D). .. At this time, the recess 44E (444E) forming the opening 43A (443A) suppresses the formation of a gap between the inner material F and the outer skin material D, and the inner material F is outside the sealing portion of the outer skin material D. It can be wrapped without leaking to the direction, and the packaged food P can be stably molded. Further, the inner material F can be pushed downward inside the packaged food P by the action of the inclined portion 44F (444F), and the shape of the shoulder portion PA of the packaged food P can be reliably formed.

In the first to third embodiments, three means for arranging the inner material F on the outer skin material D have been described, but depending on the physical characteristics of the inner material F and the amount of supply of the inner material F to the outer skin material D, etc. It may be selected as appropriate.

The description of the molding apparatus for the packaged food P according to the embodiment of the present invention is generally as described above, but the present invention is not limited to this, and various modifications can be made within the scope of claims. In the above description, the holding device 27, 227, 327, 427 and the support device 29 are provided so as to be able to move up and down so as to approach and separate from the inclusion device 25 (425) without raising and lowering the inclusion device 25 (425). , These are relative ones, and any device may be fixed and the other device may be raised or lowered.

Further, in the pair of plywood 44 constituting the inclusion unit 43, the inside facing each other is fixed as a swinging center, and the outside is swiveled up and down to swing the plywood. It is also possible to open and close the inclusion unit by moving it up and down and moving the outside in the horizontal direction so as to approach and separate from each other.

Further, in the molding apparatus 1 (401) according to the first and fourth embodiments, the air pressure of the internal space 63S (463S) is supplied by supplying the compressed air A2 to the internal space 63S (463S) of the pressing member 63 (463). However, for example, it is possible to increase the air pressure in the internal space by lowering the relatively elevating piston member provided inside the pressing member 63 (463). In this case, the piston member is an air pressure raising device, and together with the pressing member 63 (463), is a bowl-shaped forming device that forms the exodermis material D in a bowl shape.

Further, in the first to third embodiments, the encapsulation unit 43 is in an open state by inclining a pair of encapsulation plates 44 in a V shape, but a state in which the mounting surface 44D of the encapsulation plate 44 is arranged horizontally. It is also possible to form the pressing surface at the lower end of the pressing member 63 on a flat surface correspondingly to the open state. Even in such a case, the peripheral portion DE of the outer skin material D can be pressed against the mounting surface 44D by the pressing member. Further, in such a case, the position of the head FT of the inner material F arranged in the central portion of the bowl-shaped outer skin material D is the same as the mounting surface 44D, or from the mounting surface 44D. It is better to place it low, and it is possible to prevent the inner material F from leaking from the packaged food P at the time of subsequent sealing. Further, in the fourth embodiment, in the wrapping unit 443, the pair of wrapping plates 444 are opened in the horizontal state, but the mounting surface 444D of the wrapping plate 444 is tilted in a V shape to be opened. It is also possible to form the pressing surface of the pressing member 463 in a V shape corresponding to the above.

Further, by making the shape of the inner material F placed on the outer skin material D, for example, an oval shape (bale shape) so as to correspond to the shape of the opening 43A (443A), the outer skin material D and the inner material D are formed at the time of folding in half. No voids are formed between the materials F.
