Note that the vertical movement actuator 69 can be omitted by replacing the vertical movement actuator 63 with an actuator that can move up and down further and controlling the vertical movement position of the lifting member.

  As understood from the above-described configuration, the disk 41 is rotated when the pusher 55 is positioned above the disk container 37 as shown in FIG.

  The inner packaging material feeding means 29 is detachably provided on a support frame 71 provided integrally on the front surface of the frame main body 15. More specifically, the inner packaging material feeding means 29 includes a pair of screw conveyors 75 that are rotated by a motor 73 attached to the support frame 71 at the bottom of the inner packaging material hopper 77 so as to be freely rotatable. The inner packaging material hopper 77 is detachably attached to the support frame 71 together with the screw conveyor 75. A metering pump 79 is detachably attached to the front end portion (left end portion in FIGS. 1 and 2) of the inner packaging material hopper 77.

  The metering pump 79 serves to feed a fixed amount of the inner packaging material 5 to the inner packaging material supply nozzle 27, and includes a casing 81 that can be attached to and detached from the inner packaging material hopper 77. As shown in FIG. 5, an opening 81 </ b> A communicating with the inner packaging material hopper 77 is provided in a horizontal direction at the side of the casing 81. In addition, a vertical opening 81 </ b> B is provided in the upper portion of the casing 81. Furthermore, a discharge port 81C is provided on the opposite side of the opening 81A of the casing 81, and a connection pipe 83 that can be connected to the connection pipe 47P in the inner packaging material supply nozzle 27 is provided in the discharge port 81C.

  A rotor 85 is housed in the casing 81 so as to be reciprocally rotatable. The rotor 85 is rotated forward and backward by an appropriate actuator (not shown) such as a motor or a link mechanism. The rotor 85 has a groove-shaped communication path 85A and a cut-off surface as it is on the outer peripheral surface. 85B. As shown in FIG. 5, the communication path 85A rotates the rotor 85 so that the opening 81A and the opening 81B communicate with each other and the opening 81B and the discharge port 81C communicate with each other. It is to be switched. When the opening 81A and the opening 81B are in communication with each other, the blocking surface 85B blocks the communication between the discharge port 81C and the communication between the opening 81B and the discharge port 81C as shown in FIG. In this state, the communication of the opening 81A is blocked.

  A cylinder 87 communicating with the opening 81 </ b> B is provided upright on the casing 81, and a piston 87 </ b> P is fitted in the cylinder 87 so as to be movable up and down. The piston 87P is moved up and down by an appropriate vertical movement actuator 89 (see FIG. 1) such as a fluid pressure cylinder or a ball screw mechanism mounted on the front surface of the frame body 15.

  With the above configuration, when the openings 81A and 81B are in communication with each other, the screw conveyor 75 is rotated to feed the inner packaging material 5 in the inner packaging material hopper 77 to the metering pump 79 and the piston 87P in the cylinder 87. Is lifted, the openings 81A and 81B of the casing 81, the communication passage 85A of the rotor 85, and the lower side of the piston 87P in the cylinder 87 are filled with a plastic inner packaging material 5 such as, for example. Thereafter, the rotation of the screw conveyor 75 is stopped, and the rotor 85 is rotated to connect the opening 81B and the discharge port 81C. When the piston 87P is lowered, the inner packaging material 5 filled in the communication passage 85A is pushed out to the discharge port 81C by the inner packaging material 5 in the cylinder 87 and fed to the inner packaging material supply nozzle 27. Become.

  At this time, the feeding amount of the inner packaging material 5 fed to the inner packaging material supply nozzle 27 is defined by the descending amount (lowering position) of the piston 87P from the ascending position. Therefore, a constant amount of the inner packaging material 5 can be always fed to the inner packaging material supply nozzle 27 by keeping the rising position and the lowering position of the piston 87P constant. Further, the feed amount of the inner packaging material 5 can be controlled by controlling the lowered position of the piston 87P and / or the raised position of the piston 87P.

  Further, in the above configuration, the inner packaging material 5 is sucked into the cylinder 87 by raising the piston 87P in the cylinder 87, and the inner packaging material 5 is discharged from the cylinder 87 by lowering the piston 87P. When discharging (feeding) a large fixed amount of the inner packaging material 5, it is possible to discharge the inner packaging material 5 in an accurate amount at a high speed. Therefore, in the production of the encapsulated food 9, the production efficiency can be improved and the product can be stabilized.

  In the lower position of the mounting plate 19, when the packaged food 9 is manufactured, the lifting support means 91 that supports the packaged food 9 descending from the opening 19 </ b> H of the mounting plate 19 from below is moved up and down. It is provided freely. And the carrying-out conveyor 93 which carries out the foodstuff 9 to the next process is provided adjacent to this raising / lowering support means 91. As shown in FIG. In addition, since the structure of the said raising / lowering support means 91 and the said carry-out conveyor 93 is well-known, for example, as described in the said patent document 1, the more detailed description about the said raising / lowering support means 91 and the carry-out conveyor 93 is given. Omitted.

  In the configuration as described above, when the outer skin material 3 formed in a flat disk shape is placed on the traveling stock conveyor 25, the outer skin material 3 is transported in the direction of the transport conveyor 23 and detected by the optical sensor. However, in the initial stage, since the outer skin material 3 does not exist on the transport conveyor 23, it is transferred onto the transport conveyor 23 as it is. Then, the outer skin material 3 on the conveyor 23 is placed on the placement plate 19.

  When the skin material 3 is placed on the placement plate 19, the plurality of shutter pieces 21 </ b> S (see FIG. 6) in the shutter device 21 are closed, and the skin material is placed at the center of the opening 19 </ b> H of the placement plate 19. Centering is performed to align the center of the three. At this time, the central portion of the outer skin material 3 enters the opening 19H and is recessed to form a concave portion 3A, and the lower portion of the central portion of the outer skin material 3 rises to the lifting support means 91. (See (1) and (2) in FIG. 6). When the next skin material 3 is placed on the stock conveyor 25 and this skin material 3 is detected by the optical sensor, the travel of the stock conveyor 25 is stopped and enters a standby state. Further, the pusher 55 shown in (1) of FIG. 6 is in a state of being stopped at the lowest position. That is, the elevating member 65 of the vertical movement actuator 63 is lowered to the lower end, and further, the rod clamp 67 provided in the vertical movement actuator 69 is lowered to the lower end.

  As described above, when the outer cover material 3 is centered with respect to the opening 19 </ b> H of the placement plate 19, the placement plate 19, the shutter device 21, and the lifting support means 91 are relatively positioned with respect to the inner packaging material supply nozzle 27. Be raised. Then, the peripheral edge 3B of the outer skin material 3 is pressed and fixed to the placement plate 19 by the dough pressing member 51 (simulated in FIG. 6) provided in the inner packaging material supply nozzle 27 (see FIG. 6). (See (3)). As described above, after the outer peripheral edge 3 </ b> B of the outer skin material 3 is pressed and fixed, the vertical movement actuator 69 is operated to raise the rod clamp 67 with respect to the elevating member 65. The pusher 55 provided to be freely movable up and down is opened, the opening 49H of the nozzle 49 is opened, and the inner packaging material 5 is supplied to the concave portion 3A of the outer skin material 3 (see (3) in FIG. 6). At this time, the elevating support means 91 is gradually lowered as the outer covering material 3 is gradually expanded by the supply of the inner packaging material 5 (see (3) and (4) in FIG. 6).

  Then, the piston 87P of the metering pump 79 is lowered to feed a predetermined amount of the inner packaging material 5, and then the pusher 55 is lowered to close the opening 49H of the nozzle 49 (FIG. 6). (Refer to (4)). At the same time, the rotor 85 in the metering pump 79 is reversely rotated to stop feeding the inner packaging material 5. Then, the inner packaging material 5 is filled again into the cylinder 87 of the metering pump 79. As described above, in the state where the opening 49H of the nozzle 49 is closed by the pusher 55 and the feeding of the inner packaging material 5 from the metering pump 79 to the inner packaging material supply nozzle 27 is stopped, the pusher is actuated by the operation of the vertical movement actuator 69. It is lowered slightly until 55 is lowered, and is inserted into the inner packaging material 5 (see (4) in FIG. 6).

  Thereafter, when the vertical movement actuator 63 and the vertical movement actuator 69 are operated to raise the pusher 55 to a position higher than the disk 41 in the solid material supply means 31, a recess 5C is formed in the inner packaging material 5 (FIG. 6 (5)). At this time, the concave portion 59 is formed on the lower surface of the pusher 55, and air is ejected from the air outlet 59H, thereby preventing the inner packaging material 5 from adhering to the lower surface of the pusher 55. Then, when the disk 41 in the solid material supply means 31 is rotated, the accommodation hole 43 in the disk 41 is positioned above the inner packaging material supply nozzle 27, so that the solid material 7 accommodated in the accommodation hole 43 is removed. It is dropped and supplied into the recess 5C of the inner packaging material 5 (see (5) in FIG. 6).

  As described above, after the solid material 7 is dropped and supplied into the recess 5C, when the pusher 55 is lowered by operating the vertical movement actuator 63 and the vertical movement actuator 69, the pusher 55 has dropped the solid material 7. It passes through the accommodation hole 43 and is inserted into the inner packaging material supply nozzle 27. And it protrudes downward again from the opening part 49H of the nozzle 49 with which the inner packaging material supply nozzle 27 was equipped, and the said solid substance 7 in the said recessed part 5C is press-immersed in the inner packaging material 5 ((6) of FIG. 6). reference).

  As described above, after the solid material 7 is pressed into the inner packaging material 5 by the pusher 55, the mounting plate 19, the shutter device 21 and the lifting support means 91 are lowered while maintaining the vertical distance therebetween, and the dough The pressing member 51 is separated from the outer peripheral edge 3B of the outer packaging material 3, and the pusher 55 is separated from the inner packaging material 5 (see (7) in FIG. 6). Further, the mounting plate 19, the shutter device 21, and the elevating support means 91 are lowered, and each shutter piece 21 </ b> S in the shutter device 21 is closed, so that the peripheral portion 3 </ b> B of the outer skin material 3 is converged to the central portion. Then, the encapsulated food 9 is manufactured (see (8) in FIG. 6).

  By the way, when the recess 5C is formed in the inner packaging material 5 by the pusher 55, when the depth of the recess 5C is sufficiently deep and the solid material 7 can be wrapped with the inner packaging material 5, the solid material 7 is removed with the pusher 55. It is also possible to omit pressing and immersing into the inner packaging material 5. In addition, as shown in FIG. 12 of Patent Document 1, a shutter piece 21S for sealing the peripheral edge portion 3B of the outer skin material 3 is provided on the lower side of the mounting plate 19 described above. It is also possible.

  Further, as described above, when the solid material 7 in the concave portion 5C of the inner packaging material 5 is pressed into the inner packaging material 5 by the pusher 55, the solid material 3 is sealed when the peripheral portion 3B of the outer skin material 3 is sealed. When 7 is not sufficiently wrapped by the inner packaging material 5, it is desirable to do the following.

  That is, the process up to (6) in FIG. 6 is made the same. Then, the solid material 7 is pressed into and submerged into the inner packaging material 5 by the pusher 55 (see (1) in FIG. 7, the same step as (6) in FIG. 6), and when the pusher 55 is raised, the inner packaging material supply nozzle By discharging and supplying the inner packaging material 5 again from 27, the solid material 7 is reliably embedded in the inner packaging material 5 (see (2) in FIG. 7). Thereafter, the pusher 55 is slightly lowered to close the opening of the nozzle 49 (see (3) in FIG. 7).

  Then, the mounting plate 19, the shutter device 21, and the lifting support means 91 are lowered (see (4) in FIG. 7), and each shutter piece 21 </ b> S in the shutter device 21 is closed, whereby the peripheral portion of the outer skin material 3. 3B is gathered together at the center and closed (sealed) (see (5) in FIG. 7). In this case, since the inner packaging material 5 is supplied in two steps, the supply amount of the first and second inner packaging materials 5 is suppressed to be small, and the amount of the inner packaging material 5 is reduced as a whole. It is desirable to control the amount to be constant.

  As understood from the above description, since the solid 7 is dropped and supplied into the recess 5C formed in the inner packaging material 5 and the solid material 7 is wrapped with the inner packaging material 5, the solid material 7 is, for example, marshmallow. Even in the case of a relatively soft lump like the above, it can be wrapped with the inner packaging material 5 without breaking the outer shape of the solid material 7.

  Further, since the solid material 7 in the concave portion 5C is pressed into the inner packaging material 5 with the pusher 55, the solid material 7 can be reliably buried in the inner packaging material 5, and the inner packaging material 5 The solid material 7 can be easily wrapped.

  Furthermore, after the solid material 7 is dropped and supplied into the recess 5C of the inner packaging material 5, the inner packaging material 5 is further supplied and replenished on the upper side of the solid material 7, so that the solid material 7 is more reliably wrapped with the inner packaging material 5. It is something that can be done.

  By the way, the present invention is not limited to the above-described embodiments, and can be implemented in other forms by making appropriate changes. That is, in the embodiment, the case where the solid material 7 is supplied and dropped from the upper end portion of the inner packaging material supply nozzle 27 has been described. However, as indicated by an imaginary line in (5) of FIG. 6, a communication pipe 95 communicating with the vicinity of the lower end portion in the inner cylinder 53 of the inner packaging material supply nozzle 27 is provided, and the solid material 7 is removed via the communication pipe 95. It is also possible to adopt a configuration in which it is dropped.

  By configuring as described above, the pusher 55 may be raised to a position higher than the connection portion with the communication pipe 95 without pulling the pusher 55 upward from the inner packaging material supply nozzle 27. The overall configuration can be lowered.

  Further, in the above description, it has been described that when the outer skin material 3 is placed on the outer skin material support member (mounting plate) 19, the concave portion 3 </ b> A is formed in the central portion of the outer skin material 3 by its own weight. However, it is also possible to hold the pusher 55 protruding from the opening 49H of the nozzle 49 and press the outer skin material 3 in this state to form the recess 3A in the central portion of the outer skin material 3.

  Further, in the above description, the case where the dough pressing member 51 is integrally provided on the outer peripheral side of the inner packaging material supply nozzle 27 is exemplified. However, as shown in, for example, Japanese Patent Application Laid-Open No. 2009-278936, the inner packaging material supply nozzle It is also possible to adopt a configuration in which the fabric pressing member 51 moves up and down separately with respect to 27.

  The packaged food manufacturing apparatus 1 according to the embodiment has the outer cover material 3 in the same manner as in Patent Document 1 by replacing the inner package material supply nozzle 27 with a separate inner package material supply nozzle 27A (see FIG. 8). It is possible to manufacture a food package having a configuration in which the inner packaging material 5 is wrapped.

  In order to detach and replace the inner packaging material supply nozzle 27 and a separate inner packaging material supply nozzle 27A, a circumferential groove 47G (see FIGS. 3 and 4) is provided near the lower end portion of the outer cylinder 47 in the inner packaging material supply nozzle 27. It is formed. A support bracket 97 (see FIG. 1) having a semicircular recess (not shown) that engages with the circumferential groove 47G at the tip is integrally attached to the support frame 71. A clamp 99 having a semicircular recess (not shown) corresponding to the recess of the support bracket 97 is attached to the tip of the support bracket 97 by a fixture (not shown) such as a bolt. is there.

  Therefore, in a state where the circumferential groove 47G of the outer cylinder 47 is engaged with the recess of the support bracket 97 and the recess of the clamp 99 is engaged with the circumferential groove 47G, the clamp 99 is attached to the support bracket by a fixture. The outer cylinder 47 of the inner packaging material supply nozzle 27 is supported by the support bracket 97 by being fastened and fixed to the front end portion of 97. Therefore, by removing the fixture 34 from the bracket 33, the solid material supply means 31 can be removed from the bracket 33 and the inner packaging material supply nozzle 27. Further, the clamp 99 is loosened and the clamp 99 is released. Since the inner packaging material supply nozzle 27 can be removed from the support bracket 97 by detaching, the solid material supply means 31 and the inner packaging material supply nozzle 27 which are unitized are sequentially or integrally removed from the frame main body 15. It is something that can be done.

  The separate inner packaging material supply nozzle 27A includes an outer cylinder 47A corresponding to the outer cylinder 47, and the outer cylinder 47A has a peripheral groove 47GA corresponding to the peripheral groove 47G, as shown in FIG. And a connection pipe 47PA corresponding to the connection pipe 47P. A lower portion of the outer cylinder 47A is provided with a nozzle 49A and a fabric pressing member 51.

  Further, in the outer cylinder 47A, a lower elevating rod 57L integrated with a pipe-like upper elevating rod 57U penetrating the plug member 101 provided in the upper part is provided, and the lower elevating rod 57L A valve member 103 corresponding to the pusher 55 is provided at the lower end. The valve member 103 opens and closes the opening 49AH in the nozzle 49A, and the valve member 103 is provided with an air outlet 103H that ejects air downward.

  In order to move the elevating rods 57U and 57L up and down, a vertical movement actuator 105 such as a fluid pressure cylinder is provided above the outer cylinder 47A, and a piston rod that is moved up and down by the vertical movement actuator 105 is provided. For example, the vertical actuator 107 and the lifting rod 57U are connected by a dovetail structure. Therefore, the opening / closing operation of the opening 49AH in the nozzle 49A is performed by moving the valve member 103 up and down by the vertical movement actuator 105.

  Instead of the inner packaging material supply nozzle 27, the peripheral groove 47GA of the outer cylinder 47A in a separate inner packaging material supply nozzle 27A is engaged with the concave portion of the support bracket 97, and the concave portion of the clamp 99 is engaged with the circumferential groove 47GA. To do. Further, the clamp member 99 is fastened and fixed to the support bracket 97 by a fixture, whereby the separate inner packaging material supply nozzle 27A can be supported by the support bracket 97. Therefore, by connecting the connecting pipe 47PA to the metering pump 79, the inner packaging material 5 can be fed from the metering pump 79 to the inner packaging material supply nozzle 27A.

  As understood from the above description, the encapsulated food manufacturing apparatus 1 manufactures a triple structure encapsulated food 9 having a solid 7 and a double structure encapsulated food that does not have the solid 7. It is something that can be done.

  In addition, when manufacturing the double-wrapped food without solids, the solid supply means 31 is held in a resting state (stopped state), and the pusher 55 is opened and closed to open and close the nozzle 49. It is also possible to use the inner packaging material supply nozzle 27 as a valve and to supply only the inner packaging material 5.
